(57) Abstract:

The invention relates to the field of textile production and used for dyeing cloths. The device contains Krasnopolskaya paths, Krasnopillya channels connected to the output gap head for applying the paint to the canvas, such as carpet. In Krasnopolskaya pipelines built tubular elements with elastic annular chamber, which is a damper with hydraulic shock, or is battery ink fluid when changing the dye, which eliminates the mixing of dyes and their pollution. Improves the quality of the painting works. 7 C.p. f-crystals, 6 ill.

The invention relates to a device for applying a liquid processing tools on the canvas.

To capture and damping of pressure fluctuations and pressure shocks in the guide liquid pipelines known placing on them the so-called accumulator pressure, connected to the pipeline through the branch. This device operates only as long as the pipeline proceeds in the same liquid. If during operation there is a change fluid, located in the branch and one is e gradual mixing with the following liquid and pollution. This problem becomes noticeable in the inlet piping to the application heads, guides liquid covering means in the form of dye solution. The relevant settings are known, for example, application Germany NN 2900712 A1 and 3315770 A1. If, for example, was first produced staining red, and then it moves on to the yellow color, it is located in the branch and on one side of the accumulator pressure of the residual amount of "dead" red paint will gradually be mixed with yellow paint and turn it into an orange.

The basis of the invention lies in the task of creating a device for influencing flowing in the supply line to the cylinder, for applying a quantity of liquid, where the change processing tools rely on its minimum possible residual quantity.

This task is solved by the inventions described in paragraph (1 formulas.

"The tubular element itself is known as the sleeve valve from the application Germany N 4031228 A1, but more similar in function as a shock absorber hydraulic shock is known from the patent Germany N 1096694 B. It performs almost the same function as already apoplectically coaxially continues its inner periphery without the need for that branch or similar spatial zones to be filled with liquid when the accumulator pressure must perform its function.

This function has two aspects.

If at the point of connection is supported by the pressure corresponding to the pressure of the flowing fluid, the bag plot remains essentially cylindrical and simply continues the pipeline with almost the same diameter. In this state, the tubular element, as is known, can serve as a damping element, because when the hydraulic shock elastically pliable bag little plot moves back and absorb hydraulic shock.

Another aspect of active influence on the course of the processing means in the supply line, in which the battery is connected with the spatial zone of greatly reduced pressure, i.e., evacuated tank. In the annular chamber due to this, there is a vacuum, so that the sleeve section in the annular chamber is inflated by receiving a part of the flowing processing means. This can be used for disabling the pump, calling for the processing means, to take part in the processing means of the down-stream AOR is Yami. If the application device interrupts the flow of the processing means and simultaneously connecting the point of connection of the annular chamber with a sparse space, the sleeve section is absorbed in the annular chamber increases due to this, its volume and removes from the gap in the input channels and cracks processing tool, resulting in its application to the canvas immediately, effectively and completely interrupted.

Constructive execution of the tubular element in its preferred form can be implemented according to the point 2 of the formula. Radial flanges limit together with the inner periphery of the tubular section, mainly rectangular cross-section of the annular space which is open towards the axis of the pipeline and closed tubular section. When creating a vacuum bag area is deformed radially outward into the annular space.

The connection of the ends of the tubular section with radial flanges suitable to implement through the clamping rings (item 3), which may be specified in point 4. Corresponding conical ring, it is advisable to pull with radial flanges by means of axial clamping screws (item 5), preseverence, located according to p. 6.

The application device may be provided, at least one shut-off valve and one flush valve for PP 7 and 8. The drawing shows examples of carrying out the invention.

In Fig. 1 and 2 is depicted passing through the axis of a longitudinal section of two structurally different forms of execution used in the invention, the tubular element.

Fig. 3 and 4 depict schematic of two important applications of the tubular element.

Fig. 5 depicts a circuit supplied by a tubular element dyeing or pattern forming device for fast color change.

Fig. 6 depicts a workflow diagram of the installation according to Fig. 5 when the so-called cutoff.

Marked on Fig. 1 overall POS. 100 tubular element is inserted into the pipeline, forming a supply line 10 to the cylinder 48 for applying a liquid processing means (Fig. 5), the ends 10',10" which have the same diameter and coaxially opposite each other, i.e. are located on the same axis A distance corresponding to the length of the tubular element 100 in the direction of the axis A. the Inner periphery of the pipe 10 continues between the ends 10', 10" by voobrajeniea surface 1 is surrounded with radial clearance by the body of G, containing coaxial to the axis A of the tubular section 2, the ends of which are welded to the radial flanges 3, 4, which form passing inside almost to an imaginary cylindrical surface 1 of the peripheral protrusions 5, 6. The inner peripheral surface 7, 8 of the radial flanges 3, 4 are tapered so that the tapered surface tapering axially inward. The angle of the cone is in this example, run about 30o.

On both ends of the tubular element 100 is provided by a conical ring 11, 12, coaxial to the axis A and having in passing through the axis of A longitudinal sectional shape of the area with radial flanges 13, 14 and axially protruding from it to the middle of the axial shelf 15, 16, the inner periphery of which lies essentially in the area of the imaginary cylindrical surface 1. The outer periphery of the axial shelves 15, 16 forms a corresponding tapered surface 17, 18, which has the same cone angle that the conical surfaces 7, 8, and located radially tightly inside them.

On the outer ends of the tapered rings 11, 12 through the seal 22 posted by mounting the nozzles 23, the inner peripheral surface 24 which lies essentially on an imaginary cylindrical surface is for other known way.

Radial shelf 13, 14 passes in front of the end face of the radial flange 3, 4. In this zone there is distributed on the periphery, the axial indicated in Fig. 1 only their middle lines tightening screws S, which pass through holes 19 in the radial shelves 13, 14 and into threaded holes 20 in the radial flanges 3, 4.

Between the inner peripheral protrusions 5, 6 pass filter section 30 of elastically pliable on the surface of a material, such as elastomer or rubber, the ends 30', 30" which are between pairs 7, 17 8, 18 cone surfaces and when tightening the clamping screws are clamped between them. The sleeve section 30 is able without effort cylindrical shape and passes essentially in the area of the cylindrical surface 1.

Between the radial flanges 3, 4 are formed, therefore, the annular chamber 25, which is radially inside limited sleeve section 30, radially outward of the inner periphery of the tubular section 2 and the axial flanges 3, 4 and 21 of the connection through which the inner space of the annular chamber 25 may be provided with zones of different pressure.

If in the annular chamber 25 is supported, with whom, 1 solid line condition and serves as a damping element to occur in the supply line 10 hydraulic shock. If annular chamber 25 through 21 connections communicates with sparse space, i.e., evacuated vessel, a sleeve section 30 is inflated thanks to its elasticity inside the annular chamber 25, as shown in Fig. 1 by the dashed line. As a result of this inside the sleeve section 30 occurs increased, which absorbed the liquid from the supply pipe 10. For example, the fluid may otkazyvatsa from the output described below in connection with Fig. 4.

It is evident from Fig. 1 also shows that inside the tubular element 100, thanks to its described implementation no significant radial clearances or other dead space, in which when changing the fluid could remain appreciable quantities. The supply line 10, in contrast, continued smoothly tubular element 100. Emptying can be carried out fully, as the smooth, continuous pipe.

Details of the tubular element 100' in Fig. 2, functionally corresponding to the parts shown in Fig. 1, are denoted by the same reference position.

Another difference is the presence of the axially external retaining ring 29, which is on the outside adjacent to the connecting sleeve 23.

In Fig. 3 schematically shows an example of application of the tubular element 100. Through the conduit 31 to the pump 33 draws from a stock processing fluid and transports it into the supply lines 10, 10' which is connected to a tubular element 100 to the left in Fig. 3. Right tubular element 100 is attached to the end 10" of the inlet pipe 10, moving on to the valve 34, which selectively connects the supply line 10 with the pipe 35 or 36. To place 21 connecting the annular chamber 25 through the pipe 37 is attached is indicated by a circle filled with compressed air zone 38, dominated by regulated pressure corresponding to the pressure in the supply line 10.

If the pump 33 for some reason creates a hydraulic shock or if the switching valve 34 hydraulic shock occurs on the other hand, the elastically pliable tubular section 30, which takes until the radially outward moreover, the pressure remains essentially unchanged. Hydraulic shock, therefore, elastically absorbed and are damped.

In Fig. 4 depicts a dyeing device, in which the pump 33 through line 31 draws from the stock (not shown) of dye solution and transports it to the supply line 10, which on the one hand attached to the tubular element 100, and the other comes out of it further. In the space 21 is connected through a branch 37 is installed switching valve 39, which can selectively connect the branch 37 through line 42 with an area of 38 adjusted pressure, or through a pipe 41 with a sparse space 40, which is continuously evacuated using a vacuum pump.

The pipeline 10 transports the dye solution on the arrow to the head 50 for applying housing 45, passing transversely across the width of the canvas. The body is made of at least one feed channel 46 in which the ends of the inlet pipe 10 and which, in turn, is directed to the output gap 48, passing transversely across the width of the canvas. The output gap 48 open ends on the surface 47 of the slide, on which the belt is transported in the direction of the arrow.

If necessary, abrupt cessation of dyeing, the pump 33 is disconnected and at the same time the valve switch 39 so that the branch 47 through conduit 41 connected with the sparse space 40. Due to this, the pressure in the annular chamber 25 drops sharply until the pressure in the thin space 40, resulting in an elastically pliable tubular section 30 is inflated up to the indicated dashed line position 32, so that the internal volume increases. The liquid required to fill the bag section 30 in position 32, is sucked from the inlet pipe 10, which is on the left side is closed by a pump 33, which absorption occurs mainly from the right in Fig. 4 part of the inlet pipeline. Located in the exit slit 48 of the dyeing solution is sucked off at this back in direction of the arrow 49, so that the output of the dye solution from the output mouth of the exit slit 48 stops abruptly. Depending on, does the valve 39 connection zone 38 is adjusted pressure or with sparse space 40, the tubular El the wives of another exemplary embodiment of the tubular element, according to the invention. We are talking about the device for applying a pattern forming means on canvas, mainly used for dyeing of carpets. A special hallmark of plants for dyeing carpets is the presence of two crashpadder tracts, and with the help of KRASNOPEREKOPSKOGO valve may quickly switch to paint one crashpadder tract to paint another crashpadder tract. There are many installed directly next to each other across the width of the canvas krasnoperekopskomi valves, actuated together or separately, so that the installation, you can also receive pattern of the carpet cloth.

Construction details KRASNOPEREKOPSKOGO valve and cooperating elements are the subject matter of the application of the FRG N 19705258.4-26, revealed the contents of which it should be invoked.

Both crashpadder tract indicated in Fig. 5 as a single unit POS. 60 and 60' attached to Krasnoperekopsk valves 80, which, as already mentioned, installed in a large number next to each other. Each of these krasnoperekopskomi valve 80 has three shown in Fig. 5 bottom left operating positions 80', 80", 80"'. Carboprost 10 to the exit slit 48, ending the pile is continuously guided by the arrow of a cloth In the carpet material. From each KRASNOPEREKOPSKOGO valve 80 to the exit slit 48 leads feed channel 46, and the output gap 48 passes across the width of the sheet and is common to all feed channels 46. Coming from a separate feed channels 46 number of dye solutions are mixed at the edges in the output gap 48 is only slightly. The width of each supplied from a separate Krasnoperekopsk valve 80 plot sheet may be 20-60 mm, and the preferred steps are, respectively, 25 and 50 mm When the width of the carpet fabric 5 m and the step 25 mm there are therefore two hundred krasnoperekopskomi valve 80.

Because both crashpadder paths 60, 60', on the one hand, and on them, and diagrams in Fig. 3,4,6 are functionally related to each other parts, they are denoted by the same reference position.

On crashpadder tract 60 pump 33 through line 31, which is equipped with a filter 51, draws from the tank 52 of the dyeing solution of the first kind, for example red, and transports it to the supply line 10, in which is installed an optional filter 53 and is about using Fig. 1-4 species. After passing through the tubular element 100 dye solution into the inlet pipe 10 in the dispenser 55, in which it is distributed through branches 56, the number of which corresponds to the number krasnoperekopskomi valve 80. Each individual branch 56 extends in a corresponding krasnoperekopskomi valve 80.

Krasnopolye tract 60' includes, as seen from Fig. 5, the same are denoted by the same reference positions of the elements, however, in order to distinguish them from crashpadder tract 60, they are partially provided with a stroke. In the vessel 52' contains a different dye solution, such as blue.

In depicted in Fig. 5 the state in which the individual krasnoperekopskomi valve 80 is in a position 80', and the valve 54 to position 1-2 (designated 1 and 2 connections are connected), transported by the pump 33 red dye solution is sent to the collector 62, and from the exit slit 48 to the canvas In not to apply any dye solution.

In order to avoid incrustations simultaneously with drawing on the canvas In red dye solution can function and right Krasnopolye tract 60', however, as is evident from Fig. 5, depicted here, the state is called to flush valve 59, selectively directing the dye solution or channel 61, or a collection of 62, the contents of which can be later reused. The flushing valve 59 also has three positions shown in Fig. 5 at the bottom right. Position 59' corresponds to the position according to Fig. 5, in which a blue dye solution is drained from the tank 52 in channel 61. In position 59" communication with the reservoir 58 is absent. In position 59"' dye solution is directed from the reservoir 58 to the collector 62.

When switching KRASNOPEREKOPSKOGO valve 80 to the position 80 blue dye solution is applied to the canvas, and the red dye solution gets into the reservoir 58.

In position 80"' all connections are locked.

Provided by the evacuated space 40 in the form of a vacuum tank, permanently maintained at a low pressure by a vacuum pump 63. The evacuated space 40 through the piping 41 is attached to the two control valves 39, 39', each of which corresponds to one of crashpadder circuits 60, 60' and which selectively connect the piping 41 through line 42 with the space 38 is adjusted pressure or through the pipe 37 with the annular chamber 25 of the tubular ale is but contributes to the spatial proximity of the individual krasnoperekopskomi valve 80 to the exit slit 48, which for this purpose are mounted in a common cylinder 50 for the application.

To demonstrate the rapid change of color in Fig. 6 depicts the process of switching valves in the implementation of the so-called "cut-off". "Cut-off" is a temporary staining of the short length of the pattern in a different color while painting the first color. I.e. canvas continuously move and paint the first color. Then switch to another color, and then again further staining the first color. The short length of the pattern is used to control the skip dyeing in a different color during subsequent dyeing the first color, so that, if necessary, we could still influence the filling of dye solution of a different color, not allowing for this downtime.

Assume for this purpose that all Krasnopillya valves 80 simultaneously switch from one dye solution to another, i.e. from one solid color dyeing to the following without obtaining the pattern due to the different actuation neighboring krasnoperekopskomi valve 80.

In Fig. 6 above shows the timeline in seconds. Shown below are included positions of the individual elements denoted by reference oloto applied In the dyeing solution from the tank 52, i.e. red, which is represented by the black strip 64 on the letter B. Shutoff valve 54 is in contrast to the position in Fig. 5, in position 2-3, so that the red dye solution could get to Krasnoperekopsk valves 80.

If necessary, the cutoff for the transition to a blue color at point 65 include pre for a few seconds, the pump 33' for the blue paint crashpadder tract 60', which sends it to the transported quantity in the collector 62, since the valve 54', in contrast to the position in Fig. 5, is first in position 1-2.

At the point 66 of the valve 54' is switched so that the blue dye solution is directed not to the collector 62, and in position 80' KRASNOPEREKOPSKOGO valve 80 in the channel 61. At the same time shut-off valve 54, which at first were connected places 2 and 3 are connected so that the red dye solution could fall in the output gap 48, switches 2-1, in which red dye solution is drained into a collection of 62. Further, simultaneously, at the point 66 of the control valve 39 is switched to position 2 to 3, in which the tubular element 100 is connected with a sparse space 40 so that the sleeve section 30 is inflated to position 32, and con is the first solution a few plays ago so almost instantly stops the flow of the red dye solution onto the canvas Century, Starting from the point 66, the canvas remains, therefore, for a short time white that marked POS. 67.

At the point 68 Krasnopillya valves 80 switch 80, so that in the output gap 48 is transported blue dye solution, which within a short period of time mixed with a red dye solution in krasnoperekopskomi valves 80, the feed channels 46 and the output gap 48, resulting in the canvas is formed In the mixed paint, denoted by the dashed cross-wise area 69. At the point 70 is peeled from the red paint Krasnopillya valves 80 are switched back to the red paint, but do not contain red dye solution, since the shutoff valve 54 remains in the position 2-1, so that the red dye solution is given before krasnoperekolsky valve 80 to the collector 62. Therefore, on the canvas In nothing is applied, which is indicated by the white box 71.

At point 72 at the same time switch Krasnopillya valves 80 in position 80 for blue dye solution, the control valve 39' is in position 2-1 for the collection of the AK on canvas applied In pure blue dye solution, that are marked with a shaded area 73. The remains of the red dye solution in krasnoperekopskomi valves 80, the feed channels 46 and the output gap 48 were washed in phase 69. The length of the section 73 if necessary, choose, in order to produce the required color definition or colorimetry. Then in the area of 75 corresponding stages happen Vice versa, so the point 74 again continues staining 76 red.

You should pay attention to the fact that from the point 66 to point 72 is just 1.2 seconds. This corresponds to the duration of the transition to another color. Accordingly, the time for the passage 75 is 1.2 seconds. When the speed of the moving web 15 m/min transit time is 1.2 seconds means a period of only 30 cm, which can be a transition from one color to another without the presence of mixed shades in the beginning of the new color. Is depicted in Fig. 6 example concerns the cutoff, in which after switching to blue 73 again there was a return to red 76. It is clear that for frequent change of color achieved at point 72 the state of the supplied components just keep it, so all the remaining length of the blade, as the sample 2, is colored red.
