A disadvantage of the known devices is that the dressing on it, despite the tight tightening, does not exclude the possibility of displacement of coils of binding material along the surface of the skein or bundle. This reduces binding reliability. The aim of the invention is to increase the reliability of the binding of the device for tying the coils of wire or bundles of rods by eliminating the possibility of displacement of the turns of the binding material during transport and shifting of the coils or packs. To achieve this product, the device for tying coils of wire or bundles of rods, contains a binding material, a cutting mechanism with movable and fixed blades, a flexible material, including a fork, mounted on the rod, driving it back and forth. the vertical plane, and the mechanism for fastening the ends of the binding material placed under the fork, including a rotating element, is equipped with a flashing mechanism, made in the form of a reciprocating actuator moving in the direction intersecting the direction of movement of the plug, a hollow needle mounted on a harness consisting of not less than two telescopically connected soft elements, of which the inner one is connected to the mechanism of the binding material, and the outer one - with the needle and its drive while the fork of the bending mechanism is arranged to rotate around its axis by 180 when moving in one direction, and at the ends of the teeth of the fork there are coaxially arranged openings for the passage of the needle. The drive shaft of the fork of the bending mechanism of the binding material can be placed in a sleeve fixed against rotation, with diametrically opposite grooves made on the rod, each comprising two straight sections connected by two screw sections, and in the sleeve are mounted with the possibility of movement in the grooves of the rod videos. The movable HO5S cut-off mechanism can be mounted on a spring-loaded lever. The lever and the fixed knife are installed in the cavity of the wiring element connected to the needle, and the lever is filled with a groove and is installed. It is designed to interact with the power cylinder rod, mounted above the wiring. The rotary element of the mechanism for fastening the ends of the obvzochnogo material can be made in the form of a disk with two spiral-shaped notches with pointed upper edges, and on the inner side of each end of the plug are freely mounted on axes in the vertical plane and spring-loaded stops. Fig. 1 shows a device for wrapping coils of wire or bundles of rods, a general view (the extreme positions of the moving parts of the mechanisms are indicated by a dash-dotted line); in fig. 2 is the same, the view in the glider of FIG. 3 - node I of FIG. 1, in FIG. 4 - section A-A of FIG. 1, in FIG. 5 - node II of FIG. one; FIG. 6 section bb FIG. 5, in FIG. 7, node III of FIG. 1, in FIG. 8 is a view along arrow B in FIG. 7, in FIG. 912 shows the positions of the plug and the binding material at different stages of the tie (the arrows indicate the direction of movement of the plug, after which it takes up the position shown in the drawing); FIG. Figure 13 shows a part of the rod driving the fork of the binding material. A device for tying coils of wire or bundles of rods contains a feed mechanism that has an unwinding device 1 for placing the wire 2 for a tie, a housing with idle correct rollers 4 1 and driven feed rollers 5, 1 gear 6, electric motor 7 and co. mandoapparatus 8.: The flashing mechanism contains a pointed needle 9 in the form of a gutter and a hydraulic cylinder 10. The needle .9. rigidly attached to the outer pipe 11 of the telescopic wiring, which is attached to the rod of the hydraulic cylinder 10 and held by four support rollers 12. The inner pipe 13 of the telescopic wiring is connected to the housing 3 at one end. The cutting mechanism contains a trough-shaped lever 14 installed in the pipe 11 on axis x 15 and pressed with a plate-like spring 16. Cut-off plates 17, 18 with curved cutting surfaces are fixed on the lever 14 and pipe 11, respectively. The drive of the cutting mechanism is pneumatic cylinder 19 installed on the foundation by means of a cantilever support 2 above the lever 14. The bending mechanism contains a fork 21 at the ends of the teeth of which one hole 22 is made, the dimensions of which exceed the cross section of the needle 9 approximately two times. On the inner side of the ends of the plug 21, the cams 23 are mounted on the axles x 24 with tension springs 25, 26. The plug 21 is attached to the end of the actuator stem 27. On the surface of the rod 27, there are two straight grooves 28 with a bend of 29 grooves and two curvilinear screw grooves 30, which go into straight grooves 28 at the point of bend 29. There are two rollers 31 of the sleeves 32, which span the rod 27 along a sliding fit. . The second end of the rod 27 is attached to the rod of the hydraulic cylinder 33 with the possibility of axial rotation relative to the latter. The yoke 32 and the hydraulic cylinder 33 are mounted on a common frame 34 fixed permanently. The bonding mechanism for the ends of the wire contains a disk 35 mounted on the shaft of a low-speed electric motor 36, and the command device 37i The disk has two spiral-shaped tapered notches, the upper edges of which in the narrowed part are pointed at an angle of 90-120. Wrap hank 38 is placed on the turntable (on the hell, not shown) with the axis 39 of rotation. The table has | sealing levers 40, 41. The binding device is equipped with contactless (e.g., KVN-15 type) sensors 42-46 and recording plates 47-50 for operating the sensors. The device works as follows. In the initial position, the mechanisms occupy the following position (FIG. 1, 2). The fork 21 is raised to the extreme upper position, the needle 9 is retracted to the extreme right position, the wire 2 is tucked into the roller 5, and its front end is near the cutting plates 17, -18, the coil 38 with the rolling profile (wire rod) is fed to the position for tying with the turntable. The pulse dd of the device start is received either from the sensor of the presence of a riot, or from the start button of the control panel. The wrapping process begins by lowering the plug 21. At the same time, the rod 27 moves relative to the sleeve 32, the rollers 31 of which are rolled in the straight grooves 28 and in the bend 29 from position I to position II (Fig. 3). At this point, the plate 47 approaches the sensor 42 (FIG. 9), the latter is activated and gives a signal to turn off the hydraulic cylinder 33 to stop the plug 21, the openings 2 of which at this moment are located at the needle 9. The signal issued by the sensor 42 is simultaneously a control signal driven by a needle, 9 and driven by a wire feed 2, the hydraulic cylinder 10 moves the outer tube 11 with the needle 9 in the support rollers 12, at the same time, the electric motor 7 through the gearbox .6 the feed rollers 5 moves the wire 2 along the inner tube 13 at a speed equal to To move the needle 9, the needle 9 passes through the near hole 22 of the plug 21, then pierces the coil 38, then passes through the second hole 22 and stops due to the full exit of the rod of the hydraulic cylinder 10- (this position is shown in Fig. 1 by a dash-dotted line ). After stopping, the needles 9 continue to feed the wire 2, which slides along the channel of the needle 9, thus stitching the hank 38 over its cross section. After storing a length sufficient for the tie, the tie wire is stopped. A signal for stopping the feed rollers is provided from the commander 8. The same signal is used for the length of the needle 9 to its original position. When the needle 9 reaches the initial position, the sensor 46 from the plate 50 is triggered and outputs a signal to the action of three executive mechanisms: a cutting mechanism, a bending mechanism, and sealing levers. At the same time, the pneumatic cylinder rod 19 presses on the lever 14, the cutting plates cut the wire 2, the plate 17 returns to its original position, and the lever 14 takes the same position under the action of the spring 16, the sealing arms 40, 41 compress the skein 38 in two sections and keep it from moving in the process of viscous. The hydraulic cylinder 33 begins to move up the brush - shaft 27 with a fork. C. the yoke 32, the rollers 31 of which, rolling around the curved grooves 30, unfold the plug 21 half of its full rotation when the extreme upper position is reached. The wire 2 is thus transferred from the initial position (Fig. 9) to the second position (Fig. 10). At this moment, the sensor 43 is activated from the plate 48 and gives a signal to the action of the hydraulic cylinder 33, which begins to lower the plug 21. rolls around in straight grooves 28 and with a slight turn, direct the END of the plug 21, the accessory wire and the binding wire 2 to a wide part of the turntable 35, which is automatically set to the desired position by means of the command device 37, while pulling the wire through the turns the disk 35 and the ends of the wire 2 are bent through the edges of the holes 22. Upon further movement, it pulls up, seals the bind section of the coil 38, slips through the holes 22 and releases in the lowest position of the plug 21 (Fig. 12). At the time of tension and slippage relative to the ends of the plug 21 of the wire 2, with its last action, it unfolds and lowers the cams 23, then when the cams 23 are weakened under the action of the springs 25, 26, they take the same position and the bent ends of the wire 2 come out of the holes 22 (Fig. 12) . In the lowest position of the stem 27 with the plug 21, the plate 49 is close to the sensor 44, which gives you a signal to switch the hydraulic cylinder to move the fork 21 upwards. The ends of the wire 2 remain in the tips of the rotary disk 35. When the rod 27 with the plug 21 moves upwards, the rollers 31 roll around first along the upper part of the straight grooves 28, then go to the curved grooves 30. Therefore, the plug 21 moves upward first without turning, and then turns over skein 38 half a turn and occupies the starting position. The plate 47 acts on the sensor 45, which supplies a signal for turning off the hydraulic cylinder 33 and turning on the electric motor 36 for rotating the rotary disk 35 (in FIG. 2, counterclockwise). The ends of the wire 2 are picked up by the pointed edges of the narrowed part of the cutouts and twisted. The command device 37 stops the electric motor 36, turns it on reverse and stops it in the initial position (Fig. 2). The ends of the wire 2 are released. At the moment when the rotary disk 35 stops, the command device 37 issues a signal by which the seal marks 40, 41 are retracted, and the coil 38 is turned around axis 39 at an angle of 90 if the skein link is provided in four places, or at an angle of 120 if in three places . Trailer turn switches (in hell, not shown) automatically stop and turn on the signal at the start of work of the trap device. In this case, all the actions described above by the mechanism are repeated.

FIG. 2 After completing the last setting of the coil, the tying device is not activated. Said skein is removed (e.g., by a total spread of the table), and a new skein is placed in its place. Further, the entire binding cycle is repeated as described above. Binding of coils of wire with the help of this device makes it possible to eliminate the defect arising from the creeping of coils of the binding wire and the subsequent tangling of coils. Such tangled coils of wire go to scrap. Due to the relatively high cost of wire, the use of this device provides a significant economic effect from reducing scrap.
