Description

one

The invention relates to packaging equipment and can be used for wrapping rolls, for example, metal tape.

A similar device is known, comprising inclined guides for feeding coils, supporting and supporting swiveling take-up rollers, a device for feeding binder material and a wrapping mechanism.

The aim of the invention is the possibility of packing rolls of various diameters. This is achieved in that the device is provided with a key lock mounted on an inclined guide, the keys of which are separated from the reference roller. The keys can be spring-loaded, while the protruding part of them has bevels in the rolling direction of the roll.

FIG. 1 schematically shows the proposed device; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - view along arrow B; in fig. 4 - key lock in conjunction with the coiled roll.

The coil tying device comprises inclined guides 1 for feeding the coils; an anvil 2 holding the roll before feeding it into the area of the tie; supporting and supporting swivel take-up rollers 3; attachment 4 for feeding the binding material; fixed-wiring 5 and folding 6 that guide the binding material around the cross-section of the bound roll; an uncoiler 7, on which is a roll of strapping tape; a binding mechanism that includes a clamp 8 of the front end of the tie material, a clamp 9 of the rear end of the tie material, a knife 10 for cutting the binding material and two electrodes

11 with welding equipment carrying out one-sided contact welding of the binding material wrapped around the section of the bound coil; keyboard lock 12, locking coiled rolls in

receiving pivot rollers 3 and consisting of the required number of spring-loaded key 13, having -crosses on a length protruding beyond the guides, in the rolling direction of the knitted roll; key

a retainer 12 is mounted on a non-sliding wall 14 of inclined guides 1, the other wall 15 of which is movable. Therefore, the width of the wrapped coils may vary within wide limits.

The coil tying device operates as follows. The wrapped roll is on the stop 2 in the inclined guides 1, the cable G is disconnected, the take-up swivel rollers 3 are rotated on the axis so that the support roller is recessed by the RHP roll roll plane, and the reference roll is LIFTED. When the device is in operation, the stop 2, which is held in place by the saddle, is lowered and the latter spontaneously rolls in the direction of the roller to the normal roller. Meeting the keyboard lock 12 on its way, the tied roll acts on the windowed ends of the spring-loaded key 13 and alternately depresses them. As the roll section is released, the keys 13 return to the initial position under the action of springs, thereby locking the roll in the receiving swivel rollers 3, which then turn with the associated roll into a horizontal position, while the axes of the stationary 5 and the flip 6 wires combine . The folding wiring 6 is closed and the device 4 sets the binding material into the combined wiring. Then, successively, the clamp 8 clamps the front end of the strapping material, device 4, reversing it, wraps it around the cross-section of the knotted roll, the clamp 9 clamps the back end of the bonding material, the knife 10 cuts the strapping material and the electrodes 11 perform one-sided resistance welding. After that, the clamps 8 and 9, the knife 10 and the electrodes 11 at the same time tap t-to its original position. One viscosity is ready. For the next viscosity, the take-up swivel rollers 3 rotate the rotating coil around the desired angle (set depending on the number of voices on the roll), and the wrapping operations are repeated. After the last spin is completed, the rollers 3, turning, release the bound roll and return to their original position. The subject of the invention 1. A device for wrapping coils, for example, a metal tape, comprising inclined guides for feeding coils, supporting and supporting swiveling take-up rollers, a device for feeding obvzochnogo material and a bracing mechanism, characterized in that, for the purpose of packing coils of various diameters, it is provided with a key lock mounted on an inclined guide, the keys of which are spaced from the support roller. 2. A device according to claim 1, characterized in that the keys are spring-loaded, while the protruding part of the guide has bevels in the rolling direction of the roll.
