The invention relates to the field of packaging and can be used mainly in wire drawing shops of metal-working plants, as well as in wire and grade rolling mills for hot and cold rolling.

A device for wrapping wire coils is known, comprising a mechanism for horizontal and vertical wire feeds, in which, to increase the reliability of grip and tightening of the mechanism for twisting the ends of the wire, it is made in the form of two impellers with jaws and a hollow shaft, one impeller is fixed on the end of the hollow shaft having in the inner surface a multiple threaded thread, and the second impeller - at the end of the rod, placed inside the hollow shaft and having an external thread, and between the free ends A compression spring is located on the rods and on the hollow shaft, and on one impeller the sponges are spring-loaded 1.

However, viscous wire coils using this device, Despite tight tightening, during transportation and overloading does not guarantee that the strap turns to one side of the coil, which leads to fluffing and wire entanglement, metal loss and requires additional time. Very tight viscous increases the risk of breaking of the binding material in case of overloading, but does not completely eliminate the possibility of shifting the binding threads.

In addition, the device can only bind coils with wire and is not suitable for banding with tape.

It is also known a device for the wrapping of objects, comprising a mechanism for feeding the binding material, a cutting mechanism, a mechanism for the binding of the binding material, including a lifting-lowering fork. On

the ends of the teeth of which are formed by holes, a piercing mechanism, a table for fixing objects, a mechanism for fastening the ends of the binding material with cutting plates and a system for controlling the position of the fork 2, located below it.

However, in the known device, when the plug is retracted upwards after the task of binding material into the mechanism for fastening the ends, it is possible to pull out the binding straps of the wire. The end may fall back into the hole of the plug and be pulled out of the buckle zone, and the deflecting cam with a large bend in the end of the wire may not be sufficiently effective. Correction

this defect requires the use of manual labor to correct or skip viscous. In addition, the prior art device can bind coils only with wire and is not suitable for banding with tape. These drawbacks reduce the technological capabilities and reliability of the device.

The aim of the invention is to increase the reliability of the device for tying objects by preventing the ends of the binding material from being pulled out of the fastening mechanism during the fork lifting process.

The goal is achieved by the fact that in the device for tying objects, mainly wire coils and bundles of bars, containing a binding material, a cutting mechanism, a flexible material for binding, including a lifting-lowering fork at the ends of the teeth of which are formed openings, a firmware mechanism table for fixing

The mechanism for fastening the ends of the binding material with cutting plates and the system of controlling the fork position, the mechanism for fastening the ends of the binding material consists of a pair of driving electrodes with spring-loaded jaws in the lower part, one of which has one V-shaped the gripper, and the other two, located symmetrically to it of a similar gripper, the sponges are spring-loaded along the electrodes and their grips are reinforced in front of the working ends of the electrodes, while the electrodes with the jaws are installed with air the possibility of passage into the holes of the plug, and in the table there are slots for the teeth of the plug and sponge electrodes.

The drive of the electrodes can be made in the form of a helical gear, and the electrodes are mounted console on the drive nut.

In addition, on the top of the electrodes at the working end can be fixed visors of wear-resistant material.

To tie objects with tape material, a support plate can be fixed in the fork of the V-shaped grippers.

One of the cutting plates can be closed on one electrode, and the other on the gripping of the sponge of the other electrode.

In this case, longitudinal guides for V-shaped grippers can be made in the side walls of the slot.

I; in fig. 4 - node P in FIG. one; FIG. 5 shows the node III in FIG. 1 (electrodes are reduced); in fig. 6 is a view A of FIG. 5 (one plate not shown), option for banding; in fig. 7 - the same, option for a barring wire; in fig. 8-12 are the stages of wrapping the riot (the arrows indicate the direction of movement of the fork, after which it takes the position shown in the drawings).

A device for wrapping objects includes a feed mechanism including an unwinding device 1 (Figs. 1 and 2) for placing a binding material 2 (wire or tape), a housing 3 with idle correct rollers 4 and driven feed rollers 5 connected to a gearbox. 6, the electric motor 7 and the control unit 8.

The mechanism includes a pointed needle 9 in the form of a groove (Fig. 1 and 2) driven by a power cylinder 10. The needle 9 is rigidly attached to the outer tube 11 of the telescopic wiring, the outer tube 11 is connected to the brush of the power cylinder 10 and is held by four supporting rollers 12 The inner tube 13 is connected to the housing 3. The cutting mechanism contains a lever 14 in the form of a groove mounted in the outer pipe 11 on the axles 15 and preloaded with a plate spring 16. The cutting plates 17 and 18 with the curvilinear cutting surfaces are fixed on jbiHare 14 and pipe 11 respectively. The drive of the cutting mechanism - power cylinder, 19 is installed on the foundation by means of a cantilever support 20 above the lever 14.

The bending mechanism contains a fork 21, at both ends of the teeth of which is formed along the aperture 22, the size of each aperture is approximately 2 times larger than the cross section of the needle 9. The plug 21 is attached to the end of the shaft-shaft 23. On the surface of the shaft-shaft 23 there are two straight grooves 24 with a bend of the groove 25 and two curvilinear screw grooves 26, passing into the straight grooves 24 at the bend 25 (Fig. 3). Two rollers 27 of the yoke 28 encompassing the rod-shaft 23 along a sliding fit enter the grooves. The second end of the shaft-shaft 23 is attached to the rod of the drive 29 screw motor with the possibility of axial rotation relative to the latter. The yoke 28 and the screw motor drive 29 are mounted on a common frame 30 fixed permanently.

The bonding mechanism for the ends of the binding material (Fig. 5) contains two electrodes 31, located one opposite the other (coaxially) and facing each other with working ends. The electrodes 31 are enclosed in housings 32, fitted with protective visors 33 of wear-resistant material and mounted by means of cantilever supports on a screw mechanism 3.4, which is driven by an electric motor 35. The upper edge of the protective visors 33 is placed at the level of the supporting surface of the table 36 to level the bay 37. Clamping jaws 38 and 39 are located below the electrodes 31 in the sockets 40 of the casing 32 slidably in the direction along the electrodes.

Clamping jaws 38 and 39 are extended in front of the working ends of 41 electrodes 31, and one 38 has a V-shaped grip 42, and the other 39 has symmetrically similar two grippers 43 to it (Fig. 6 and 7). To use the bandage material in the forks of the arms of the V-shaped grippers 42 and 43, the plates are fixed and the sponges are mounted interchangeable.

Each clamping jaw 38 and 39 is preloaded with spring 44 and is secured against turning by screw 45. Clamping jaw 39 has a shank 46. The cutting plates 47 and 48 are installed with the overlapping of the cutting edges in the position of clamping the binding material with electrodes 31. In the table 36 slots 49 and guides 50 are made according to the number of places on the bay 37. The width of the guides 50 corresponds to the thickness of the ends of the arms of the V-shaped grippers 42 and 43 for the latter to freely enter the guides 50. The table 36 has an axis of rotation 51, the pressure levers 52 and drive st la (not shown).

The strapping device is equipped with contactless (e.g., type) sensors 53-58 and recording plates 59-.63 for triggering the sensors.

The device for tying objects works as follows.

In the initial state, the mechanisms of the device occupy the following position (Figs. 1 and 2): the fork 21 is raised to the extreme upper position, the needle 9 is retracted to the extreme right position, the binding material 2 is loaded into the feed rollers 5, and its front end is near cutting plates 17 and 18.

Coil 37 of the rolling profile (wire rod) is fed to the tie position on the bearing surface of the table 36 (Fig. 5). An impulse to start work is supplied either from the sensor of the presence of the bay 37 on the table 36, or by the start button from the control panel. The trimming process begins by lowering the plug 21. At the same time, the motor drive screw 29 of the screw motor moves the shaft-shaft 23 relative to the sleeve 28, the rollers 27 of which run in straight line grooves 24 and along the bend of the groove 25 from the "1 to" position 2 (Fig. 3). In position 2, the plate 59 approaches the sensor 57 (FIG. 8), the latter operates and gives a signal to turn on the screw motor drive 29 to stop the plug 21, the holes 22 of which at this moment are located at the level of the needle 9. The signal issued by the sensor 57 simultaneously The drive control signal of the needle 9 and the feed drive of the binding material 2. The power cylinder 10 moves the outer tube 11 with the needle 9 B of the support rollers 12. At the same time, the electric motor 7 through the gearbox 6 feed rollers 5 moves the connection material 2 along the inner The tube 13 at a speed equal to the speed of movement of the needle 9. The needle 9 passes through the near hole 22 of the plug 21, then pierces the bay 37, then through the second hole 22 and stops after the full output of the rod of the power cylinder 10 (this position is shown in Fig. 1) - dotted line). After stopping, the needles 9 continue to feed the binding, the material that slides along the needle channel 9, thus forgiving the bay 37 over its cross section. After reserving a length sufficient for binding, the supply of binding material 2 is stopped.

A signal for stopping the feed rollers 5 is emitted from the commander 8. The same signal is used to retract the needle 9 to its original position. When the needle 9 reaches the initial position, the sensor 58 from the plate 63 is activated and generates a signal for the action of three mechanisms: cutting, bending and clamping levers 52. At the same time, the rod of the power cylinder 19 presses

the lever 14 and rotates it on the axis x 15. The cutting plates 17 and 18 cut the binding material 2. Then the rod returns to its original position, and the lever 14 under the action of the spring 16 takes the same position. The clamping levers 52 clamp the coil 37 in two places along the sides of the viscous position and keep it from moving during viscous. The screw motor drive 29 begins to move up the shaft-shaft 23 with the plug 21 in the holder 28, the rollers 27 of which, rolling in curved vitovyh grooves 26, turn the plug 21 half of its full rotation when it reaches the extreme upper position. The length of the banding material 2 is thus transferred from the initial position (Fig. 8) to the second position (Fig. 10). At this moment, the sensor 55 is triggered from the plate 60 and generates a signal for switching the screw motor drive 29, which lowers the plug 21 to the lowest position when the holes 22 are located opposite the electrodes 31 and the jaws 38 and 39, and the ends of the binding material 2 remain in holes 22. At this point, the plate 61 approaches the sensor 56, which outputs a signal to turn on the electric motor 35. The latter actuates the screw mechanism 34 and begins to reduce the covers 32. The electrodes 31 and the jaws 38 and 39 enter the holes 22 In this case, the clamping jaws 38 and 39, with their V-grips 42 and 43 pushed forward in movement, release the ends of the binding material 2 from the holes 22. When the clamping jaws 38 and 39 approach each other, the V-shaped gripper 42 is inserted into the double V-shaped gripper 43, orient the ends of the binding material 2 against each other, and the forks of the grippers compress them. With further movement, the clamping jaws 38 and 39 compress the springs 44, and the covers 32 with the electrodes 31, while continuing to move, bring the ends of the binding material 2 together.

The binder material 22 is weighted down. Since at this time the ends of the claws are in the guides 50, they perceive part of the load from the side of the binder material on the visors 33 and the housings 32.

In this case, the protective visors 33 directly impact the knitting material and prevent premature wear of the electrodes 31. Before the working torch faces of the electrodes 31 are brought closer, the cutting edge of the cutting plate 47 is pressed onto the ends of the bonding material 2, through them to the cutting plate 48 and presses the clamping sponge 39 with the shank 46 to the bottom of the gdezd 40. After that, the detachable plates 47 and 48 cut off the ends of the braiding material 2 (Fig. 5). To the cutting stroke of the cutting plates 47 and 48, the working electrodes of the electrodes 31 compress the rollers of the binding material 2. After the required force is applied to press the electrodes 31, the electric motor 35 is switched off by automatic equipment when a certain overload current is reached, and simultaneously a signal is given to connect the welding voltage to the electrodes 31 The time delay for welding is set by p, barely time. At the end of the time control with the same time, a signal is given for the dilutions of the electrodes 31 and at the end of the dilution from the plastine 63, the sensor 58 is triggered, which gives a signal to lift the plug 21 to the initial position and retract the clamping levers 52. Limit switches (limit switches (not shown) ) clamping levers give a signal to turn the table 36 around the axis 51 at an angle of 90 ° if the bay 37 is provided in four places, or at an angle of 120 ° if such places exist. The limit switches for turning the table (not shown) automatically stop and issue a signal at the start of the binding device. These mechanisms are repeated. After the last baying, the tying device is not activated. For this, a counting number (number of turns of the table) is provided in the control circuit. The wetted bay is removed, and a new bay is placed in its place. Next, the entire wrapping cycle is repeated. Binding of coils of wire or bundles of rods using the proposed device allows the use of binding material of different profiles (for example, wire or tape). In comparison with the known in the proposed device, the mechanism for connecting the ends of the binding material is more reliable in operation. Viscous density is obtained, the appearance of the coded bay is improved (there is no twisted knot). In addition, the likelihood of bonding between the coils with the ends of the bracing material during handling operations is reduced.
