The invention relates to a holding device of a tubular shell, intended for filling viscous or granular filling, packaging machine, in particular a machine for clipping preferably sausages, which contains a filling tube for filling the tubular casing filler, such as sausages. In addition, the invention relates also to a machine for clipping.

The specified device retaining shell or braking device includes a first brake ring, which can be installed on the water pipe coaxially with it, and the inner diameter of the ring is greater than the outer diameter of the filling pipe. On the inner surface of this ring is the first braking means, along which the shell can be directed towards filling the filler against the current on the shell of the friction force.

The present invention also relates to a machine for clipping for the manufacture of products in the form of sausages, in particular sausages, with viscous or granular filler, such as sausages, which can be filled tubular casing, for example casings. Machine for clipping contains a filling tube for filling tubular casings with filler, located on the filling tube for the AU shell and holding device for attachment to the shell, which can extend in the direction of fill specified friction force directed opposite to the direction of the fill.

Usually in the production of, for example, sausage sausage beef sausage served syringe in a machine for clipping through the filling tube crimp and separating device. In a machine for clipping filler stuffed in compressed from one end of the first clip of the tubular membrane, which is then crimped to the second clip. Shell received sausages then separated from the remaining stock of the shell and thus obtained the sausage product is withdrawn from the machine for clipping.

When the filler which, in addition to the sausage meat, can also be, for example, coating or sealing composition, is fed through connected with filling machine filling pipe in compressed from one end of the tubular shell at the outlet of the filling tube is formed product in the form of sausages. Shell, the stock of which is manually or automatically pre-stretched on a filling pipe or which is formed from a flat film, folded and sealed around the filling tube for the formation of tubular form, is extracted from the water pipe under the action of the filling pressure.

In known machines for clips is of the brake ring or brake device shell is located around the outlet part of the filling pipe and includes an annular rubber flange. The brake device has the capability of elastic effects on the filling pipe, clutching her wrapper. When this occurs the force of friction at the stage of filling the regulatory pulling casings, in particular sausage, located on the filling pipe of its stock. Thus, the brake ring allows to make sausage with the required degree of filling.

Such holding or braking device described in the German patent application 102005044879. The known device includes a support bracket, which can move parallel to the axis of the filling pipe. In the support bracket can be inserted completely covering the filling pipe of the brake ring, which exerts pressure on passing between the brake ring and the filling pipe shell for impact force of friction. By means of the crank gear to the stage of filling out the brake ring can move along with the shell on the support bracket at a certain distance in the direction of pulling or in the opposite direction of the contraction. When moving the brake ring in the opposite direction fill direction is formed volume, which can come filler, thus, with continuous filling of the shell can be further increased machine performance is for solutions.

However, the known holding or braking devices have certain disadvantages. For example, initially determined by the choice of the brake ring friction force is constant at least over the next process, and during the continuous process, it cannot be changed. This change is possible only with a substantial interruption of the process. When replacing the shell to provide the same force of friction and, therefore, the same braking effect, you must either replace the brake ring brake ring with a different inner diameter or other braking performance, or change, i.e. increase or decrease, the amount of compression of the brake ring. In any case, as already mentioned, the process must be interrupted. Precise braking or impossible, or very difficult. It may also be necessary to replace the brake ring when the pressure filling or changing the magnitude of compression of the brake ring.

The present invention consists of creating a restraint shell and machine for clipping, devoid of the above disadvantages. In particular, the present invention is the creation of the restraint shell and machine is Lipovaya, allows for easier adjustment created by the restraint of the friction force in accordance with the conditions of production and/or material of the shell.

This problem is solved in the holding device, the characteristics of which are described in paragraph 1 of the claims. In the following paragraphs 2-24 claims described preferred embodiments of the invention.

In particular, the restraint of the tubular shell, intended for filling viscous or granular material in a packaging machine, in particular a machine for clipping, and preferably in a machine for clipping sausage, contains a filling tube for filling the tubular casing filler. The restraint system includes a first brake ring, which can be mounted on the filling tube coaxially with it, and its inner diameter greater than the outer diameter of the filling pipe, and on its inner surface is first braking means, along which the sheath can be moved in the direction of filling the filler against the current on the shell of the friction force. On filling the pipe can still be installed the second brake ring, on the outer surface which is located opposite the braking means. The shell can be sent between the first medium spans the PTO brake, the first brake ring and the counter means for braking the second brake ring, moreover, the second brake ring has the ability to move in the direction of fill for application to the shell specified value of the friction force by the first braking means of the first brake ring and the counter means for braking the second brake ring. Thus, regardless of the material of the shell and/or pressure filling can easily and accurately set the necessary friction force to ensure optimal braking performance.

The frictional force can be applied to the shell in different ways. For example, the shell may be in the middle between the first and second brake rings. Thus, the first braking means of the first brake ring and the second or opposite the braking means of the second brake ring form oppositely oriented areas of contact or the contact surface between which may be supplied shell. To establish the necessary friction force by moving the first brake ring in different positions on the shell may be the effect of clamping force acting on the line or surface.

In one preferred variant of the invention, the braking means of the first brake ring is first formed coaxially with him a braking surface, a conical tapering towards the attachment of the filling. Counter means braking of the second brake ring may be formed of the second coaxial with him a braking surface, a conical tapering in the direction of filling. The value of the slope of the second conical braking surfaces of the second brake ring is preferably at least approximately equal to the value of the slope of the first conical braking surface of the first brake ring. This reduces attached to the unit area of the surface force in comparison with the known solution, which, in contrast to the application of force at a point or along a line that is more gentle on the material of the shell. Similarly it is possible to manufacture the second brake ring of flexible or providermessage material so that when the braking could be formed, the site of contact of the second brake ring, which contact with the inner annular surface of the shell or the first braking surface of the first brake ring. In this case, the simplest solution is the possibility of entering into contact with the second brake ring with the inner annular surface of the casing and the first braking surface of the first brake ring only line. It is possible, in particular, at low pressure filling, when the sealing effect can be small. However, if the filling pressure is high, the flexible or elastic material of the second brake ring is compressed when moving relative to him first brake ring so that the second brake ring is formed similarly the second cone or tapered braking surface. This second braking surface interacts with the first conical braking surface of the first brake ring.

In addition to the above arrangement for the application of the friction force through the shell between the first and second brake rings, there is also the possibility of application of the friction force to the membrane through its direction by approximately Z-shaped path between the first and second brake rings. Acting on the shell friction force occurs when you change the size of the area of the membrane in contact with the corresponding surface of the brake rings. This change in size occurs as a result of changes in contact angle under which the sheath is wrapped around the relevant parts of the brake rings. Resizing mentioned section of the casing is provided solely by the movement of the first brake ring relative to the second brake ring and easily managed.

Preferably on the inner surface of the PE the first brake ring is the first deflecting section braking, forming a first braking means shell. On this part of the shell can be ignored for the formation of the first bending about Z-shaped trajectory. On the outer surface of the second brake ring may be located a second counter-deflection plot of braking, that is, the second or the oncoming vehicle braking shell. On this part of the shell can be ignored for the formation of the second bending about Z-shaped trajectory. The movement of the first brake ring may change approximately Z-shaped trajectory of the shell and, consequently, the size of the area of the shell, which is included into contact with the deflecting parts of the brake rings.

Preferably, the first brake ring contains a guide surface along which the shell passes before you get in the first deflecting section. This guide surface smoothes the envelope, folded on the filling tube for the formation of the stock shell. Thus, during retraction of the sheath prevents the formation of folds in the field of brake rings. This is important because the folds with sharp corners can cause damage to the membrane, leading manufactured products in the form of sausages in the state of worthlessness, or can cause rupture of damaged membranes, which then leads to the permanent the major downtime.

The position of the brake ring on the filling pipe depends on various factors. The first brake ring can be installed upstream from the second brake ring in the direction of fill or can be installed on the water pipe from the bottom stream from the second brake ring. However, at any location, it is important that the deflecting areas of these two brake rings were facing each other to ensure that deviations according to the invention.

The first brake ring can move in different directions. The adjustment can be made, for example, manually or by electric motor. In one preferred variant of the invention, the first brake ring is moved by the actuator. This drive unit can easily operate and ensure accurate setting of required friction force. The actuator may be electric, pneumatic or hydraulic control.

To prevent undesirable movement of the first brake ring after you install the necessary friction force must be fastened, preferably by means of locking, locking the axial position of the first brake ring.

In another preferred embodiment of the invention includes an adjusting device is to maintain a predetermined frictional force. Such a device can smooth out uneven shell, such as variation of its thickness or surface roughness, or can compensate for fluctuations in the pressure of the fill.

Preferably there is a means of sealing to prevent the ingress of filler in the cavity between the filling pipe and the stock shell.

The seal means may be formed in various ways. For example, the seal means may be a second brake ring. Thus, the "inhibitory" and "o" functions can be combined into a single node. In this case, the second brake ring made of a suitable flexible or elastic material, not only elastically deformable seals, but strong enough to effect the braking. Braking is ensured by the aforementioned clamping force produced by the movement of the first brake ring on the second brake ring and the current line or surface between two nodes regardless of external contour or geometry of the second brake ring. As already mentioned, the surface compression is provided by the elastic deformation of the second brake ring.

The seal means may also be performed separately from the second brake ring. Thus, the deceleration is Asa" and "o" function may be provided separately from each other two nodes. The seal means may be positioned below the flow in the direction of filling of the second brake ring at some distance from him. Thus, it can be prevented from entering the filler in the region between the first and second brake rings and thereby the impact on the created friction.

In addition, the outer diameter of the seal means preferably at least approximately equal to the maximum outer diameter of the second brake ring.

The design means of sealing may be different. For example, it may be in the form of edge or lip seals.

If the diameter of the edge seal can be adjusted at least within a certain range, it is possible to smooth neodinakovo diameter of the shell, for example, between different production batches.

The present invention is also solved in a machine for clipping, the characteristics of which are set out in A.25 claims. Machine for clipping to produce products in the form of sausages, in particular sausages, with viscous or granular filler, such as sausages, which can be filled tubular sheath, such as casings, contains a filling tube for filling tubular casings Napo is the diameter in the direction of filling, located on the water supply pipe shell and holding device for attachment to the shell, which can be drawn in the direction of the fill, the friction force directed opposite to the direction of filling. When the holding device is made according to any of claims 1 to 24 of the claims.

Described embodiments of the restraint system according to the invention are used in a machine for clipping according to the invention, in particular in a machine for clipping sausage products of a certain type. These machines are used for the production of sausages. The holding device according to the invention can also be used in machines for solutions, which are used for the manufacture of non-food products in the form of a sausage filler is, for example, sealant or adhesive material.

Figures 1 and 2 schematically shows a first embodiment of a restraint system according to the invention, which is used in a machine for clipping, filling tube F which is shown in the drawing. Through the filling tube F filler (not shown), in this the case, sausages, can be fed in the direction R of filling, i.e. in a horizontal direction from right to left, sausage syringe (not shown) to output FM filling pipe of the sausage product W Filling tube F has a round cross section and preferably made of stainless steel.

Stock VV tubular sheath V preferably made of polymeric material located on filling tube F coaxially with its longitudinal axis M, as shown in figures 1 and 2, and extends from the right end of the filling pipe F to the left. By zigzag laying sheath V is large enough supply of VV without using the large space required for placement. Before beginning the process of filling the supply VV shell V can be manually or automatically extended on filling tube F in the direction of the exit FM. Also during the process of filling possible continuous or periodic education reserve VV shell V of a smooth film material in the form of a pipe, which is staged in stock VV.

As shown in figures 1 and 2, the tubular sheath V from stock VV continues for filling out FM tube coaxially relative to the longitudinal axis M to the Left of the exit FM filling pipe tail part of shell V gathers in folds and is crimped CL is a dog, the blend machine for clipping so that the filler could not go out. The end of shell V forms one end of the product W in the form of a sausage, which is also referred to as "the end of sausages."

Upstream from the exit FM filling tube F, i.e. in the direction opposite to the direction R of the filling, the filling tube F is the holding device according to the invention.

The specified device contains the first brake ring 10 and the second brake ring 20. Both the first and the second brake ring 10 and 20 can be made of plastic or metal, preferably stainless steel. The first brake ring 10 is located on the filling tube F coaxially with its longitudinal axis M can move or shift relative to the filling tube F. the Specified ring contains the first braking means in the form of a through channel 12, which conically tapering or conical in the direction R of the filling. Through channel 12 is directed shell V. the Inner surface 12A of the conical end-to-end channel 12, forming a first braking means to prevent damage to the shell V is homogeneous and smooth. Diameters as the right of the inlet 12b of the through channel 12 and the left of the outlet 12C significantly exceed the outer diameter napolnitel the th pipe F.

In the area of the right of the inlet 12b of the channel 12 from its outer surface in the radial direction essentially at a 90 angle departs flange 14, cast in one piece with the ring and completely surrounding the specified inlet 12b. The flange 14 is used to move manually or by using the actuator of the first brake ring 10 in the desired position parallel to the longitudinal axis M of the water pipe F. For transmission between the first brake ring 10 and the actuator (not shown) in the flange performed a series of holes 14a, which are evenly distributed in a circular direction on the flange 14 and are essentially parallel to the longitudinal axis M

As shown in figure 1, some edges of the first brake ring 10 is bevelled to prevent damage to the pass-through shell V.

The second brake ring 20, an axial length which is less than the length of the first brake ring 10, is still on filling tube F inside the first brake ring 10.

The inner diameter of the second brake ring 20 corresponds to the outer diameter of the filling tube F. For fixed installation on filling tube F, the second brake ring 20 may be held in place, for example, a latch. The tubular sheath V, compressed clip With downstream from the exit FM filling tube F, above is about to flow from the restraint system according to the invention forms a reserve VV, from which it may be stretched during the manufacturing process and pass on filling tube F and the brake ring 20. The outer diameter of the brake ring 20 is approximately equal to the inner diameter of the tubular sheath V, which has the possibility of contact with him with little effort. As shown in figures 1 and 2, the shell V passes between the outer surface of the second brake ring 20 and the inner surface of the first brake ring 10. As will be explained in more detail hereinafter, the second brake ring 20 acts as a seal to prevent the filler into the cavity formed by the filling tube F and reserve VV shell V.

Due to the fact that, as shown in figures 1 and 2, the maximum inner diameter of the tapered through-channel 12 of the first brake ring 10 is larger than the maximum outer diameter of the second brake ring 20, the latter is located in the first brake ring 10. However, since the minimum diameter of the conical end-to-end channel 12 is less than the minimum outer diameter of the second brake ring 20, the latter cannot pass through the first brake ring 10.

The second brake ring 20 can be performed in different ways. In the embodiment of the invention shown in figure 1, it is made in the form of mangynocologist. As mentioned above, this option is used to combine functions "braking" and "seal". More specifically, the second brake ring 20 includes a counter means of braking or ledge 22 passing, as shown in figure 1, right to left tilted up, for the formation of the second or counter braking means. When this shell V passes through the outer side of this ledge. As can be seen from figure 1, the protrusion 22 is in contact with the inner annular surface 12A of the first brake ring 10. When moving the first brake ring 10 to the right, i.e. against the direction R of the filling, the protrusion 22 is unbent downwards in the direction of the longitudinal axis M of the water pipe F through the tapered internal end-to-end channel 12 or the inner annular surface 12A. Thus, the tip protrusion 22 is in contact not only with the internal annular surface 12A and the inner annular surface of the shell V passing between the first and second brake rings 10, 20, but also forms a surface through which the shell V pressed against the inner annular surface 12A of the first brake ring 10. However, the contact between the tip of the protrusion 22, the inner annular surface of the casing V and the internal annular surface 12A of the first brake ring 12 can only happen what about being on the line. If a suitable filling pressure is low, the contact line between the second brake ring 20, the first brake ring 10 and the shell V may be sufficient.

As shown in figure 2, the second brake ring 20 has a triangular cross-section of the protrusion 22, which may take the form of both a normal and a truncated triangle. In both cases, the protrusion 22 is directed radially outward. As in the embodiment, the second brake ring, shown in figure 1, the shell passes through the gap between the triangular protrusion 22 of the second brake ring 20 and the inner annular surface 12A of the first brake ring 10. If the first brake ring 10 is moved from left to right, because of the conical shape of the through channel 12 of the inner annular surface 12A of the specified channel compresses the ledge 22 of the second brake ring 20 so that it is included in the contact surface with the inner annular surface of the shell V or inner annular surface 12A of the first brake ring 12. However, if the filling pressure is small, as in the embodiment of the invention shown in figure 1, may be sufficient to contact only along the line of the triangular protrusion 22 of the brake ring 20 with the inner annular surface of the shell V or inner annular surface 12A of the first brake to Liza 10.

The material of the second brake ring 20 may be different. For the simultaneous performance of the functions of sealing and braking it must be flexible or elastically deformable and having sufficient strength to provide sufficient braking force and a sufficient sealing action during compression of the protrusion 22 or triangular protrusion 22 of the second brake ring 20 of the inner annular surface of the shell V or inner annular surface 12A of the first brake ring 10 along the line or surface.

It should be noted that the first brake ring 10 can be rotated 180 around an axis perpendicular to the longitudinal axis M. in Other words, the first brake ring 10 shown in figures 1 and 2, may be positioned so that it is in the plane of the drawing rotated 180 on these two drawings.

Before the seeding operation to set the required magnitude of the friction force or the braking device of the hold, which depends upon the pressure of the filling and/or material shell V. To embodiments of the invention, depicted in figure 1 or 2, this is implemented by shifting the brake ring 10 in the axial direction. If the first brake ring 10 is moved further in the direction of the second brake ring 20, that is opposite to the direction R fill their contact areas, i.e. in the morning annular surface 12A of the first brake ring 10 and the ledge or triangular ledge 22 of the second brake ring 20, or the elastic surface of the brake ring 20, converging with each other. This causes the pressure to the contact line or surface contact areas 12A and 22 on the shell V, which, as shown in figures 1 and 2, passes between the two locations. As a result, due to the current on the shell V pressure filling, the friction force between the shell V and brake rings 10, 20 when removing the shell V of its stock on filling tube F is increasing. Thus, increased resistance to retraction of sheath V and the friction force.

Higher resistance may be required when the retraction of the sheath material V during the filling of the sausage product W, for example, when the machine is operated at high pressure filling and retrieval performance shell V should be limited to the adjustment of the friction force. A higher frictional force can also be necessary in the case of very hard material shell V to ensure its retraction without folds.

If, on the contrary, the brake ring 10 is displaced along the axis in the direction R fill the gap between the sections 12A and 22 contact the brake rings 10, 20 and line or surface pressure between these parts is reduced. This also causes a reduction attached to the shell V of the friction force, which is preferred, for example, at the lower of galleriesjapanese or when using softer material shell V.

As can be seen from the above description of the operation of the restraint system, the sections 12A and 22 contact should preferably have the same slope. Therefore, the change in slope gradient should be applied to both the contact areas 12A, 22 equally, however, this is ensured by the implementation of the second brake ring 20 of elastic or flexible material. The change in the value of the slope of the conical surface 12A of the first brake ring 10 allows you to change the precision adjustment during installation of the friction force or braking force. If you choose a more gentle slope, to achieve the same surface pressure of the brake ring 10 must move a greater distance than in the case of steeper slope. This provides a more gradual transition, i.e. higher accuracy when installing the necessary surface pressure and, consequently, the necessary friction force or braking force. If, on the contrary, the value of the slope of the conical surfaces is increased, the accuracy of adjustment is reduced.

As shown in figures 1 and 2, the inner annular surface 12A of the conical end-to-end channel 12 is oriented so that its smaller inner diameter is directed towards R filling in the direction of exit FM filling pipe. The first brake ring 10 may also be positioned so that its lower in the morning diameter was directed towards, opposite to the direction R of the filling. In other words, in the latter case, the first brake ring 10 in the plane of the drawing (see figure 1 and 2) rotated 180. Depending on the method used to actuate the first brake ring 10 such an arrangement may be preferred. However, it should be noted that, when the brake ring 10 has excessive play due to removing the sheath V, due to the stretching of the first brake ring 10 shell in the direction R of filling, i.e. in the retarding direction, may occur braking and, therefore, to develop too strong inhibitory effect.

On figa-6C show other preferred embodiments of the restraint system according to the invention in machines for solutions according to the invention, which will be described below. Details will be described only the differences compared to the two variants of the invention shown in figures 1 and 2. Nodes that have identical structure and/or function are denoted by the same item numbers as figures 1 and 2, increased respectively by 100.

As shown in figa and 3B, machine clip includes a filling tube F a circular cross-section. As described in the above embodiment of the invention, the tubular shell V stock VV continues beyond the exit FM filling pipe coaxially with its longitudinal axis M. Exit FM filling pipe tail part of shell V gathered in folds and swaged clip With superimposed machine for clipping so that the filler could not go out.

Upstream from the exit FM filling tube F, that is, in the direction opposite to the direction R of the filling, the filling tube F is the holding device according to the invention, which contains the first brake ring 110 and the second brake ring 120. Both the first and the second brake ring 110 and 120 can be made of plastic or metal, preferably stainless steel. In addition to the restraint below the stream near the exit FM filling pipe is the means 130 of the seal, preferably made of elastomer.

The first brake ring 110 is located on the filling tube F coaxially with its longitudinal axis M can move or shift relative to the filling tube F. the Specified ring contains the first braking means in the form of a through channel 112, which conically tapering or conical in the direction R of the filling. The inner surface a tapered through channel 112 is uniform and smooth. The diameter of the left of the outlet 112b of the conical through channel 112 is considerably greater than the diameter of the filling pipe . The diameter of the right inlet s exceeds the outer diameter of the filling tube F by at least the thickness of the shell V. the magnitude of the diameter of the inlet s is such that between the first brake ring 110 and the shell V when it is pulled between him and filling tube F does not occur any retarding force of friction.

In the left hole 112b through channel 112 from its outer side in the radial direction at an angle of about 90 passes the flange 114, made in one piece with the ring and completely surrounding the specified inlet. The flange 114 is used to move manually or by using the actuator of the first brake ring 110 in the desired position parallel to the longitudinal axis M of the water pipe F. For transmission between the first brake ring 110 and the actuator (not shown) in the flange made a number of evenly distributed around the circumference of the holes a, each of which runs essentially parallel to the longitudinal axis M

In addition, upstream from the first brake ring 110 on filling tube F coaxially to the first brake ring 110 and filling the pipe F motionless installed the second brake ring 120. The second brake ring 120 in this embodiment of the invention made in the form of formatting rings. This means that the shell V Postup the maintenance of folded pleats stock VV shell, extending on this ring and thus smoothed. Formatting the ring 120 may be similarly made of plastic or metal, preferably stainless steel. Its inner diameter corresponds to the outside diameter of the filling tube F. For fixed installation formatting ring 120 may be mounted on the filling tube F by using, for example, clamps. Its outer diameter is at least not greater than the internal diameter of the tubular shell V facing downstream side formatting ring 120 in the direction of the longitudinal axis M is made annular recess 120A, which runs in the radial direction to the filling tube F. the Groove 120A passes in the axial direction from the left front edge of the formatting of the ring, facing to the first brake ring 110, the right to a depth of about one-third of the axial length of the formatting of the ring 120, i.e. in the direction opposite to the direction R of the filling. Thus, there is emerging from the formatting of the ring 120 in the axial direction outward protrusion 120b, aimed in the direction of rolling of the first brake ring 110. In the shown embodiment of the invention the outer edge of the axial protrusion 120b has a slightly larger diameter than the actual formatting ring 120, whereby the tubular sheath V, to grow Uta by formatting the ring 120, is in contact with him on a line passing through the circle around the formatting of the ring 120. Thus, when the contraction of the shell without wrinkles can be reduced to a minimum the friction between the formatting ring 120 and the tubular sheath V.

Downstream from restraint, i.e. in the direction R of the fill at the output section of the filling tube F coaxial with it still installed the o-ring 130, which forms a means of seals. In this embodiment of the invention the sealing ring 130 is made in the form of edge seal with an adjustable outer diameter. Such a sealing ring 130 is typically made of a suitable elastomer. Its inner diameter corresponds to the outside diameter of the filling tube F, and the outer diameter is approximately equal to the inner diameter of the sheath V, from which it is then in close contact. The sealing ring 130 its inner diameter is placed on the filling tube and in the radial direction acts beyond. It is inclined in the direction R of the filling. Its cross section has the shape of a parallelogram, with the side facing the filling tube F, parallel to the specified pipe. Peripheral surface of the sealing ring 130 is inclined in a direction opposite to the direction R Zap the log.

Directly in front of and behind the sealing ring 130 are adjustable ring 130A and 130b. They can be made of plastic or metal, and in the case of use in the food industry, preferably stainless steel. The inner diameter of the adjustment ring 130A located on filling tube F behind the sealing ring 130, corresponds to the outer diameter of the filling tube F. the Outer diameter of its approximately cylindrical outer surface is less than the outer diameter of the sealing ring 130. The second adjustment ring 130b is located in front of the sealing ring 130. Its inner diameter corresponds to the inner diameter of the first adjustment ring 130A. Its slightly cut on the cone outer surface inclined forward in the direction of restraint. Its maximum outer diameter is approximately equal to the outer diameter of the seal ring 130. The length of the second adjustment ring 130b in the axial direction is approximately equal to twice the axial length of the first adjustment ring 130A. In the present embodiment of the invention both adjusting rings 130A and 130b have a radial threaded holes into which are threaded set screws 130C to secure the rings in the axial direction on filling the pipe F and for adjusting the diameter of the sealing ring 130.

The tubular sheath V stretches over still installed on filling tube F formatting rings 120 and over means 130 of the seal and is served between the brake ring 110 and filling tube F. upstream from the formatting ring 220 of the tubular sheath V forms a reserve VV, and downstream from the exit FM filling tube F is crimped crimp tool, such as clips From.

As shown in figa and 3B, the first brake ring 110 can similarly move in the axial direction to the second brake or formatting ring 120 to change the resistance value of the retraction sheath V, for example, to adapt it to the selected pressure filling or type shell V.

This change of resistance to retraction of sheath V is based in this embodiment of the invention for changing the deflection shell V brake ring 110 and formatting ring 120. Shell V moves between the brake ring 110 and formatting ring 120 at approximately Z-shaped path, which runs along the outer surface of the formatting of the ring 120, then approximately radially to the filling tube F, and then in the axial direction between the filling tube F and the inner surface of the first brake ring 110. Along the path shell V passes participation is key reject or counter braking means, formed on the formatting ring 120 protrusion 120b and the first brake ring 110 of the outer edge 112d holes s. The outer edge 112d forms a first braking means of the first brake ring 110 and the protrusion 120b forms a second or counter the braking means of the second brake ring or formatting ring 120.

To increase the resistance to retraction of sheath V first brake ring 110 can be moved along the axis in the direction of the formatting of the ring 120, as shown in figa. Deviation sheath V, passing through approximately Z-shaped trajectory, increased by deflecting sections 112d and 120b brake ring 110 and the formatting of the ring 120. The increase in the variance of shell V leads to a more dense coverage of deflecting sections 112d and 120b sheath V, ie to increase the contact area of the shell V deflector sections 112d, 120b. Due to the increased contact surface sheath V deflector sections 112d and 120b increases the friction between the contact surfaces of the deflecting sections 112d and 120b brake ring 110 and the formatting of the ring 120 and the shell V, resulting in increased resistance to retraction of the sheath V.

If, on the contrary, the brake ring 110 moves away from the formatting of the ring 120, that is, as shown in figv, is shifted in the direction of filling, Velich is deviating tubular sheath V between formatting ring 120 and the brake ring 110 is reduced. This reduces the contact area of the shell V deflector sections 112d and 120b and accordingly reduces the friction between the contact surfaces of the brake and the formatting of the rings and shell V. As a consequence, decreases the resistance to contraction of the shell V.

In the described embodiments of the invention, the shell V curves between formatting ring 120 and the brake ring 110 at an angle not exceeding in each case approximately 90. However, the annular recess 120A formatting ring 120 can also be designed so that the deflecting section 112d brake ring 110 can enter the annular recess 120A. This can lead to an increase of the bending sheath V and additional increase the contact area between the shell V deflector sections 112d and 120b to further increase the resistance to contraction.

The tool 130 seals located on filling tube F downstream from restraint, made, as already mentioned, in the form of edge seal with an adjustable outer diameter. To adjust the diameter of the inclination of the edge may vary to provide the desired diameter on the outer edge of the sealing edge of the sealing ring or means 130 seals. This is achieved by changing the position of the adjusting rings 130A and 130b. As shown in figa, the slope of the edge is the means 130 of the seal is reduced by moving the adjusting rings 130A and 130b on filling tube F along an axis toward each other. This causes an increase of the outer diameter of the sealing edge of the sealing ring 130. By moving the adjustment rings 130A and 130b in the axial direction towards each other, the outer diameter edge seal 130 decreases with increasing angle of inclination of the edge seal, and its inner diameter remains unchanged. It is clear that the diameter can be adjusted only within a range, depending on the material and size of the sealing ring 130. It is also possible to move these two adjusting rings 130A and 130b on filling tube F one of them remained motionless, and the other moved in the desired direction. However, it is also possible that the diameter was changed by replacing the o-rings 130, or both replacement and adjustment rings. Depending on the required strength as the material for the adjusting rings 130A and 130b can be used a metal (preferably stainless steel) and plastics. To install the adjusting rings 130A and 130b on filling tube F may be a radial threaded holes into which can be screwed, for example, set screws 130C. However, it is also possible to install one of the adjusting rings 130A or 130b via a press fit and attach other appropriate regulating what about the ring 130b 130A or adjustable manner.

On figa and 4B shows a holding device according to the invention is the same as on figa and 3B, the description of its construction and operation are not shown. However, this restraint system is characterized by the fact that the tool 230 of the seal shown in figa and 4B variant embodiment of the invention made in the form of a lip seal. As well as edge seal 130, lip seal still installed on filling tube F downstream from restraint. The diameter of the inner cylindrical surface 230V lip seal matches the outside diameter of the filling tube F. In the radial direction of the lip seal is a ledge 230V, tilted in the direction R of the filling. The outer diameter of the lip seal is formed by an outer wall of the protrusion 230V and usually slightly exceeds the internal diameter of the shell V. Therefore, the latter is in contact with the outer diameter of the lip seal 230 under a slight tension. In contrast edging seal lip seal 130 230 has a predefined outer diameter and can be mounted on the filling tube by means of a tight fit or cure it on the filling pipe.

The restraint shown on figa essentially corresponds to the holding device shown in figa-4V. the main difference is in the orientation of the first 210 and second 220 brake ring or formatting of the rings.

The first brake ring 210 is installed coaxially filling tube F and has the same design as the first brake ring 110 shown in figa-4V. However, the first brake ring 210 is rotated 180 about an axis perpendicular to the Central axis M. This means that the conic through channel 212 of the first brake ring 210 tapers in the direction R of the filling. Because the formatting ring 220 is installed downstream from the first brake ring 210, hole 212b tapered through channel 212, which was an outlet in the embodiment of the invention according figa-4B, in this case is the inlet for sheath V, is directly adjacent to stored on filling tube F stock VV shell and smooth the folded sheath V when it is pulling from inventory VV.

As already mentioned, the formatting ring 220 is similarly mounted coaxially with the filling tube F downstream from the first brake ring 210. Compared with the formatting ring 120 shown in figa-4V, formatting ring 220 is also rotated 180 about an axis perpendicular to the Central axis M So acting in the axial direction of the edge is directed upstream opposite to the direction R of the fill.

From the described construction it is seen that the disturbances is shining areas 212d and 220b in this embodiment of the invention is also directed to each other. Starting from the stock VV sheath V, Z-shaped trajectory path extrude sheath V passes through the filling tube F between the latter and through the channel 212 by deflecting section 212d, then approximately radially away from the filling pipe F to the deflecting section 220b formatting rings 220 and on its outer circumference.

The operation of such a restraint system according to the invention is also similar to the work shown on figa-4V device. There is also a deviation sheath V is changed by moving the first brake ring 210 relative to the formatting ring 220, thereby altering the resistance to contraction of the shell.

As can be seen from tiga and 5B, the tool 130 seals coaxially installed on the water pipe downstream from the holding device. Its design and operation comply with adjustable edge seal 130 described with reference to figa and 3B.

On figa and 6C show the restraint shown on figa and 5B, in which instead of the edge seal 130 has a lip seal 230, structure and purpose of which uniquely correspond to the device and the purpose of the seal depicted in figa and 4B.

As described above, the magnitude of the holding force is set by moving in the axial direction per the CSO brake ring 10, 110, 210 relative to the second brake ring 20, 120, 220. This movement can be done manually or by a motor, for example, through a crank device or by hydraulic or pneumatic cylinders.

The first brake ring 10, 110, 210 may also have a greater width than shown on the drawings. In this case, the tapered through channel 12, 112 is made without shown protruding in the axial direction of the edges.

In addition to adjusting the displacement of the first brake ring 10, 110 can also affect the braking effect of the selection of material and, therefore, flexibility of the protruding edge of the first brake ring 10, 110.

In accordance with the above second brake ring 20, 120, 220, which can still be installed on filling tube F, and a sealing ring 30, 130, 230, which may also be still installed on filling tube F, are part of the device according to the invention. Obviously, the second brake ring 20, 120, 220 can be manufactured together with the filling tube F in the manufacture of the latter. Similarly, the sealing ring 30, 130, 230 can be installed on filling tube F in the manufacturing process of the latter. When changing the diameter of the tubular sheath V plot of the filling pipe with the holding device according to the ACLs to the invention must also be changed.

SUBSTANCE: set of invention relates to device and method of proportioning and packing. Proposed device comprises product feeder 170 with pump to allow a continuous volumetric flow, packing tube 20 connected to feeder 170 and intended for providing the stock 32 of sleeve-type package 30 that can be removed from tube 20 together with packed product. Besides proposed device comprises clamping device 150 fitted downstream of tube 20 to press filled package 30 into bundle during filling and pressing of clamping element 162 around said bundle. It has also retaining device 100 that embraces tube 20 along its edges and brake ring 110 that reciprocates parallel with the former to cause friction forces to act on package 30 in its removal. Clamping device 150 incorporates control device designed to generate squeezing and clamping force proceeding from selected portion size and continuous volumetric flow and to feed control signal to clamping device 150. Brake ring 110 is moved back on packing tube 20 towards direction of removal into position of packing volume release directly before of during squeezing and clamping. After clamping it moves forward on said tube 20 in direction of removal into working position. Product squeezed is forced into free packing volume and, after clamping, forced again into removed package 30.

EFFECT: higher efficiency of proportioner.
