BACKGROUND OF THE INVENTION

A device for banding a tape of rolled coils, for example a wire, comprising a carousel with mandrels and binding mechanisms, a device for feeding the tape, a cutting mechanism and a compactor are known.

The proposed device increases the binding tightness.

This is achieved by the fact that longitudinal grooves for the tape are formed in the inserts, and on the front sides of the mandrels there are pivoting L-shaped levers having similar flumes and clamps LT, L, from power cylinders. On this side, the levers on one side of the mandrel are located on a compactor, movable but directed from the power cylinder.

To improve the reliability of operation, the gutters are provided with under-grip straps.

To stop the belt, the compactor has a belt feed switch.

FIG. 1 shows the proposed device, side view; in fig. 2 is a sectional view in FIG. one.

The device contains a carousel 1 with onrapkamn 2 and the bounding mechanisms, a device for feeding the tape 3 in the form of regular and feed rollers 4 located on the frame 5, an uncoiler 6, mechapism with

iodine m. 7 and non-fixed 8 knives n compactor 9.

In the mandrels 2, longitudinal grooves 10 for the tape 3 are formed, and on the front sides of the mandrels, rotary L-shaped levers 11 are installed, accommodating the grooves similar to the mandrels and the clamps 12, driven from the power cylinders. In this case, the levers 11 on the one side of the mandrel 2 are located on the press, which is displaced along the guides 13 from the power box 14. The latter is located on the non-supporting frame 15.

To improve the reliability of operation, the gutters are equipped with safety straps 16, and

pressure switch 9 for stopping the belt 3 - by the belt feed limit switch 17.

The carousel 1 is mounted on the axis 18 of the fixed column 19 and rotates from the actuator 20. The levers AND are driven from the power cylinders 21 through the toothed sector 22 and gear 23. The welding heads 24 are mounted on the frame 15. Covered in the arms, the arms 25 are placed on the pressure gun 9 and driven power cylinders 26. The power cylinders 27 control the iOT strips 16, and the power C 1 cylinder 28 - electrodes with electrodes 29.

Nofiber riots are fed to the mandrel 2 devices. The actuator 20 is turned on, the card 1 rotates on the axis 18, and the driver 2 with the bumps is set to the position for tying the buits when the grooves 10 of the mandrel 2 are co-opted with the grooves of the levers 11 mounted on the fixed frame 5 and the grooves of the levers 25 on the press 9 The power cylinder 14 operates, and the compactor 9, moving along the guides 13, compresses the riots on the mandrel 2. The drive of the rollers 4 is turned on, and the binding band 3 is fed straight through the grooves of the levers 11, the mandrel 2 and the levers 25 until it touches limit switch 17, which gives impetus to the rest The drive of the feed rollers 4. The clips 12 clamp the ends of the tape 3 at the ends of the levers 11 and 25, and the tape 3 is cut off by the knives 8 and 7. The cylinders 27 installed on the welding heads 24 (Fig. 2) work, and the rods extend the copper contact strips 16. After that, the cylinders 30 move the welding heads 24 until the strips 16 come into contact with the riots. Then the lever 25 is rotated by the cylinder 26, pulled around the riot by a tape 3, placing its free end on the bar 16, and the cylinder 21 rotates the lever 11, which is wrapping the tape 3 on the other side, laying the second end of the tape overlapped on the first. The cylinder 28, the extension of the brush, rotates the electrode holder with the electrodes 29; the latter, pressing the ends of the tape 3 to the contact bar 16, turn on the welding heads 24, and the tape 3 is welded. After welding, the strip 16 is removed from under the tape 3, the welding heads 24 and the compactor 9 are retracted to their original position. The mandrel 2 rotates to the unloading position, and the next one takes its place, and the mandrel with ribs for tying. The bundle of riots is removed from the mandrel by an inclined lifting conveyor (not shown). The subject of the invention. A device for tying a ribbon of a roll, for example a wire, comprising a carousel with mandrels and banding mechanisms, a device for feeding the tape, a cutting mechanism and a press, characterized in that, in order to increase the density of the binding, longitudinal troughs for the tape, and on the front sides of the mandrels, rotary L-shaped levers are installed, having similar mandrels, troughs and clamps for the tape, driven by power cylinders, with levers on one side of the mandrel located on the The ssovatel, moving along the guides from the power cylinder. 2. The device according to claim 1, characterized in that, for the purpose of new reliability of operation, the chutes are provided with spring-loaded slats. 3. The device according to claim 1, characterized in that, in order to stop the belt, the compactor is provided with a belt feed limit switch.
