The invention of ring binders.

A device for twisting wire ties containing disc-shaped working body with a W-shaped slot for accommodating wires of the coupler and the actuator for rotation of the working body that is associated with it through the gears mounted in the housing, having in the area of the working body through the notches for charging and pass the wire tie that is larger than the slot of the working body. For ease of use by simplifying removal device with a twisted tie one of the toothed wheels placed in the zone of the grooves of the housing and the working body is installed on the end of the hub with the ability pickup and is located on the outside of the housing, bearing the working body of the gear wheel is made hollow for the passage of a rod, corresponding in shape and size to the grooves of the body [1]

Similar features analog and invention is the presence of a working body that interacts with the ends of the wire, gear sector, and also drive for rotation of the working body connected with him by sector and gear wheels.

A disadvantage of this device is the lack of its exact mechanism of stop or locking gears, bearing working in order to implement the removal of the working body with the face of the hub, because it is impossible to determine its orientation relative to the housing of the device and this makes it difficult to eat of the working body by twisting together with the device.

In addition, this device can twist the ends of the wire in the form of braids and does not allow for the twisting of the wire ends inside the ring of the harness due to the absence of the device of the working body in the form of combs.

A device for fastening a wire to a support, containing mounted on the frame correctly-feed mechanisms, the cutting mechanisms, the mechanisms of spin placed on the carriage in the guide frame and consisting of two fixed in the cheeks of the carriage covers, two drive gears and toothed sectors with slot and hole for feeding the wrapping wire located relative to the axis of rotation on the other side of the slot reels for wrapping wire rack and pinion drive and chain drive. To improve reliability by installing toothed sectors each twist mechanism in the initial position before the new work cycle it is located on the shaft with the collar slipping clutch with an asterisk and mechanisms for locking the toothed sectors, com, made on the cover, respectively podpruzhinennom finger, and drive gear mounted on the shaft of the slipping clutch and placed between the cheeks of the carriage, while the sprocket clutch has a spring-loaded sleeve and placed on the side friction, one of which is in contact with the shaft shoulder, clutch, and other spring bushing [2]

Similar features analog and invention is the presence of toothed sectors with slot included in the mechanisms of spin, as well as the locking mechanism gear sectors.

A disadvantage of this device is the complex construction of the mechanism for locking the toothed sectors, consisting of spring-loaded finger placed in the respective sector, and nests with the bevel made on the cover, respectively podpruzhinennom finger. To install the gear sector strictly in a certain position it is necessary to make the inclusion of a hydraulic cylinder drive gear sectors, resulting toothed sectors receive rotation in the opposite direction and the spring finger is in the socket cover. When this operation is performed idling involved mechanisms, which leads to excess energy. Chrome is aloki around the wire pasture fence, that the wrapping wire is the coil mounted on the carrier frame of the vehicle. Grip the ends of the tying wire is carried out through special holes in the gear sectors, where it is sent to grips feeding mechanisms. To make the twisting of the ends of the wire around the ring of the harness device cannot due to the lack of a specific mechanism to guide the ends of the wire located on a circular loom, into the holes of the toothed sectors, i.e., because of the impossibility of capturing the ends of the harness.

The closest in technical essence to the claimed is selected as a prototype device for twisting the wire knots and rings containing a means of orientation harness, mechanism twist ends of wire working bodies associated with a drive of their rotation, and the control system [3]

Similar features of the prototype and the proposed technical solution is the presence in the structures of both devices listed working bodies. The difference prototype of the invention is constructive execution mechanism twist the ends of the wire, and the control system. Significant disadvantages of the prototype should include funkcionalnogo, the described device allows to twist the ends of the wire in harness only on the outside of the ring and does not allow spin these ends inside the ring.

The basis of the invention is the task of creating such a device for twisting the ends of the wire, in which a new implementation mechanism the orientation of the threads of the loom, working bodies and mechanism for locking the toothed sectors, the rotating of the total gear provides retention harness, grip both ends of the yarn and installation of rotating sectors in the initial position, and is simultaneously twist the two ends of the wire around the body of the ring harness for both forward and reverse rotation of the sectors.

The problem is solved in that the device for a spin ends of the wire around the bundle containing the tool orientation harness, mechanism twist ends of wire working bodies associated with the actuator rotation and management system according to the invention, the tool orientation harness is made of at least three closed lap sponges mites, beveled on the end face and having one arm consisting of the United crossbar sections, through which the rotation axis ticks, and razmernostyu has an additional mechanism to twist the ends of the wire, both mechanisms are secured to the sections and made in the form of kinematically interconnected toothed sectors with a cutout for a harness and working bodies made in the form of spring-loaded die with at least two teeth, connected by rail with toothed sectors, with the locking mechanism.

In special cases the device run the teeth of the comb is tilted to the axis of its movement in such a way that between the perimeter surface of the teeth of the comb and the axis of the captured thread is formed normal.

Guides combs are placed in the center of the toothed sectors, made in the form of a tube with an inner diameter slightly larger diameter node twisting with a radial slot in the corner, not less cut gear sector and pins, connecting tube with a comb.

The mechanism for locking the toothed sectors in the form of plot threads, on the shaft of the shared gear with two tuning and one running nut, and faces running nuts in contact with the walls of the rectangle in which it is enclosed with the ability to move along the thread, and the adjustment nut is equipped with brakes.

Combs made in the form of a horseshoe with breathtaking teeth on each wire around the body of the ring harness with forward and reverse rotation of the toothed sectors.

The orientation of the strands in a tight harness and clamp them is jaws ticks mechanism orientation. The number of sponges ticks at least three dictated by the need for a secure grip and prevent slipping of the front and rear ends of the harness. Two upper and one lower lip create a small elastic juncture section of the harness, concluded between the jaws, which determines sufficiently soft and secure grip weave ends without formation of surface defects on the wire.

The closing of the jaws with overlap is necessary to prevent raspushivaniya harness during the spin ends. The bevels on the ends of the jaws are made for entry into the arc-shaped (triangular) extraction with simultaneous compression and sealing threads. Excavation sponges cover the threads, forming a harness, the shape of the cross section close to a circle or square.

Clamp mechanism orientation made in the form of articulated levers located between the cheeks of the housing. One of the levers, consisting of two connected by a crossbar sections, through which passes the axis of rotation and on which is mounted a second arm located between the sections of the first, biased by the second spring tension. This jaw design gives visacredit all, allows you to secure the axis of rotation passing through both sections of one arm, and to improve the work of the second lever from its position between the sections of the first.

The connection of the crossbar of the two sections of the lever allows you to work with two sponges as a single lever mechanism, to evenly distribute the compression force between the levers and to improve working conditions to the axis of rotation of the articulation levers.

The location of the ticks between the cheeks of the housing, i.e. in the middle of the device is dictated by their function, consisting in the capture of the harness at the intersection of the ends.

Mechanisms twist with toothed sectors are located on the outside of the sections, because the twisting of the ends of the harness is made from capture points (sponges mites) in hand.

Rotating both of the toothed sectors of the total gear reducer required for synchronous rotation, easy adjustment of the whole mechanism of the spin associated with the accuracy of the installation slots toothed sectors relative to the jaws of the mechanism of orientation. In addition, it allows rotation in both sectors mechanism in opposite directions, which stems from the construction site of slings.

Performing working is a possibility to catch the ends of the threads and make them spin around the body harness.

Install dies on fixed sectors of the guides allows rotation of the dies together with the sectors and moving them along the axis direction due to the formation of helices from the ends of the rod, on which is wound combs.

To improve the reliability of the capture of the ends of the thread chasers can have more than two teeth. With the same purpose, the teeth of the comb can be inclined to the axis of its movement along the harness in such a way that between the perimeter surface of the teeth of the comb and the axis of the captured thread is formed normal.

Location guide combs in the center of the toothed sectors and their fulfillment in the form of tubes with an inner diameter slightly larger diameter node twisting, and with a radial slot in the corner, not less cut gear sector will allow you to twist the ends of the yarn around the loom with the dense stacking of coils and with the minimum possible diameter. The amount of the latter will be affected by the number of filaments in the bundle and the inner diameter of the tube. The inner surface of the tube guide combs will produce multiple compression coils host thread, because the tube is wrapped around the body harness together with gear less cut b gear sector.

The implementation mechanism of the locking gear sector in the form of plot threads on the shaft of General conical gear with two tuning and one running nut you need to install both slots of the toothed sectors, respectively, of the common shaft gear and also in different directions, the adjustment nuts act as stops running nuts on the plot thread for forward and reverse. The contact faces running nuts with the walls of the rectangle in which it is enclosed with the ability to move along the shaft (thread), will keep the nut from rotating on the rotating shaft and to provide for its movement along the thread within the distance between the adjusting nuts. Supply adjusting nuts stoppers allows to lock them to the shaft, to prevent their movement along the shaft and to serve as stops running nuts. Using the adjustment nuts is the change in the value of mileage running nut, thus determining the number of revolutions of the toothed sectors around the body harness. If the control circuit which includes the relay of the pulse, can be attributed to the coarse adjustment mechanism speed, the locking mechanism can be attributed to the devices exact netwide horseshoe with breathtaking teeth on each end allows you to cover the body harness and implement the twisting of the ends of the yarn, the rotation of the "horseshoe" in any direction around the harness.

The analysis of the claimed device for twisting the ends of the wire indicates that the technical result achieved by carrying out the invention will be obtained by simultaneously twisting the two ends of the wire around the body of the ring harness with forward and reverse rotation of the gear sectors. The mechanism locking the toothed sectors ensures accurate installation of rotating sectors in its original position.

Device for twisting the ends of the wire around the harness 1 consists of a housing 2 (Fig. 1-10), this role is performed by the upper arm 3 of the mechanism of orientation. The mechanism Arolsen in the form of pincers. The upper lever 3 ticks, made of two connected by a crossbar 6 sections 7, attached with the axis 8 to the lower arm 9 is located between these sections. The ends of the upper and lower levers are connected by springs 10, the holding lips 11 and 12 of these levers closed up. Sponge levers, beveled at the end for entry of the harness 1, have arcuate recesses 13 and 14 to compress and hold the threads of the loom 1 from raspushivaniya. Sponge interlock levers overlap, preventing the displacement of the harness 1 vertical and horizontal axes (Fig. 1). To sections 7 housing fixed fixation devices 15 and 16, includes a toothed sectors 17 and 18 with a slot for entry of the loom. Each toothed sector engages with two parasitic gear 19 (Fig.1, 8) which engages with the toothed wheel 20. Last mounted on the common shaft 21 with a bevel gear 22. Bevel gear 22 both the fixation device is kinematically connected with the bevel gear 23 of the output shaft 24 for rotation of the working bodies connected with toothed sectors 17 and 18. On the guides 25, fixed to the end wall of the gear sector, established the working bodies of the comb 26, designed to capture the ends 4 and 5 of the thread and twist the m gear sectors springs 27. For reliable capture of the ends 4 and 5 threads harness the teeth of the comb 26 is made oblique to the axis of movement of the comb (Fig. 4-6). Circumferential surface of the teeth of the comb forms with the axis of the catch thread angle close to 90o(Fig. 6). In this case, the combs are drawn by springs 27 to the buildings fixation devices 15 and 16. For dense packing of turns of thread around the harness guides combs made in the form of tubes 28 with a radial slot, a, secured to the ends of the toothed sectors. To facilitate penetration of the harness to the center of the sector and free output node twisting radial slot, a guide tube 28 is made larger diameter node twisting and more slots b gear sector. The key 29, which is located on the surface of the tube 28, prevents cranking of the comb around the guide and yet allows it to move along the axis of the tube and compress the spring 27.

The mechanism for locking the toothed sectors in the form of plot threads on the shaft 24 total gear 23 with two tuning 28 and 29 running nuts. The verge of running nut 29 in contact with the walls of the rectangle 30, in which it is enclosed with the ability to move the thread. The adjustment nut is equipped with brakes 31 in the form VI the contacts 35 and 36 sensors speed gear sector direct and reverse action. Sector 33 is designed to interact with contacts 35 rpm sensor direct action, and the sector 34 to communicate with the contacts 36 rpm sensor reverse action. Both sectors have the ability to move around the circumference of the shaft 24 and secured therein in any angular position by means of a coupler 37. The drive device is an electric motor 38 with a safety clutch and gearbox. For winding ring harness wire through the wire 39 in the grips 40, mounted on the drum 41. Cut the yarn is made by the knife 42. In the control circuit of the device includes two relays of the counting pulses 43 and 44, containing the power supply 45, 46 and actuating relay 47, 48.

The device operates as follows. Twist the ends 4 and 5 of the wire is carried out after winding ring harness. For these purposes, used wire (wire rod) of different diameter from 3 to 8 mm, the Front end of the wire 4 is fed to the grippers 40, fixed to the drum 41. After winding harness from 3 to 14 turns the drum 41 is stopped in the position shown in Fig. 9, so that the intersection of the ends 4 and 5 on the harness was in front of the body 2 of the device for a spin ends. The latter is fed to the cross channel is kautsa, tightly covering the threads of the slots 13 and 14. After the capture of the loom, the thread is cut by the knife 42 near the wiring 39, with the formation of the end 5, and the hooks 40 are disclosed. The inclusion of the actuator 38 of the device for a spin ends is performed by the operator or the elements of automation production line of slings, while disabling it using the control circuit of the device. Torque from the actuator 38 through a safety clutch and gearbox is transmitted to the shaft 24 (turning it clockwise) and General gear 23. The gear 23 rotates two bevel gears 22 and through the shaft 21 and the gear wheel 20 transmits rotational movement to the stray gear 19 both fixation devices 15 and 16. Gear 19 rotate the toothed sectors 17 and 18 and with them working bodies - combs 26, the rotation of which is transmitted through the guide 25 or tube 28 key 29. Combs 26 perform the rotation around the body harness, while concurrently the spin of the captured ends 4 and 5 around it in different directions. Capacity helix comes from the closed jaws 11 and 12 in the side of the toothed sectors 17 and 18. The ends 4 and 5 of the thread, alternately rolling in the coils twisting, carry combs 26 along the axis of the rails and 18 around the harness 1, which pre-defined relay of the pulse and is implemented using control circuitry, and the locking mechanism. The number of coils is coordinated with the length of the ends 4 and 5, the dimensions of which are selected from those considerations that twist, set the relay of the pulse, the ends must be fully transformed into a helix. When the shaft 24 sector 33, fixed on the shaft interacts with the contact 35, transmitting pulses to the input of the relay of the pulse 43 for each rotation of the shaft 24. When the set number of pulses and therefore the number of revolutions of the shaft 24 actuates the actuating relay 47, which sends a signal to the actuator 38 to stop and the signal in the circuit of the reverse actuator 38 for switching (training) stopped the engine in reverse. Executive relay 47 also carries the command to shut off its own power supply 45 and to switch on the power supply unit 46 of the relay of the pulse 44 reverse action. In parallel with the operation of the control circuit is open and the locking mechanism. When the shaft 24 running nut 29, unable to rotate together with the shaft from contact with the rectangle 30 is moved by the thread towards the top of nastroenie account the inertia of the progress of the rotating parts of the device. The value of this path is determined in advance and adjusting nut 28 is exposed and fixed by the stopper 31 in the right place. This is the exact setup working bodies in a position in which it is possible to output node twisting of the gear sector and a new ring harness for education site.

After discharge devices twist and release the drum 41 from the harness with twisted ends are wrapped him a new ring harness. Combs 26 under the influence of spring 27 returns to its original position. Device for twisting the ends of the wire is applied to the intersection of the threads 4 and 5, and harness covers the slots 13 and 14 made on the jaws 11 and 12. After cutting the thread with a knife 42 is twist the two ends 4 and 5 around the body harness 1. The spin is in the opposite direction in comparison with the previous harness. Because at the end of the twist of the first harness was signaled in the scheme of reverse actuator 38 on the reverse, shaft 24 is rotated counterclockwise, transmitting torque to the dies 26. Chasers capture thread already other ends. Running nut 29 is moved the thread to the lower adjusting nut 28. Sector 34 communicates with the contact 36, peredavai number of revolutions of the shaft 24 actuates the actuating relay 48, which sends a signal to the actuator 38 to turn it off, and in the scheme of reverse for the preparation of a stopped motor to rotate in the opposite direction. Relay 48 also carries the command to shut off its own power supply 46 and to switch on the power supply unit 45 adjacent relay of the pulse 43 direct action. After disconnection of the electric motor 38 running nut 29 is moved to the lower adjusting nut 28 due to the inertia of the progress of the rotating parts of the device. Thus is fairly soft stop working bodies without jerks. The notches of the toothed sectors are always in the same position, at which potential output and input harness in the fixation devices 15 and 16.

According to the conducted design studies the invention in comparison with the prototype has the following advantages: the described device provides the orientation of the strands in a tight harness, keeping him at the moment twist, engagement and deformation of both ends of the yarn and the installation of a rotating toothed sectors in its original position. Due to this, the device allows you to simultaneously twist the two ends of the wire around the body of the ring harness for both forward and reverse rotation of the sectors,Revoluci around harness, containing the tool orientation harness, mechanism twist ends of wire working bodies associated with a drive of their rotation, and the control system, characterized in that the tool orientation harness is made of at least three closed lap sponges mites, beveled on the end face and having one arm consisting of the United crossbar sections, through which the rotation axis ticks, and placed on the axis of rotation between the sections of the second lever, a spring-loaded against them by spring tension, and the device has an additional mechanism to twist the ends of the wire, both mechanisms are secured to the sections and made in the form of kinematically interconnected toothed sectors with a cutout for a harness and working bodies made in the form of spring-loaded die with at least two teeth, connected by guides with toothed sectors, with the locking mechanism.
