(54) DEVICE FOR BINDING PRODUCTS

The invention relates to product packaging and packaging equipment and can be used primarily in the metallurgical industry, for example, for tying coils of STRIPED steel on a conveyor.

A device for tying products is known, comprising a conveyor for products with two mechanisms arranged on its sides for feeding the binding element and two pivoting arms for fastening the binding element 1.

However, using such a device it is possible to pack products of only a certain size.

In order to improve the tying of rolls of various dimensions in the proposed device, the levers are fixed on the carriage moving along the conveyor, and the mechanisms for feeding the binding element are mounted on brackets turning from the counter-loads for tensioning the binding element.

FIG. I depicts the described device; in fig. 2 - view A of FIG. one; in fig. 3 - section bb FIG. one; in fig. 4 shows a sequential wrapping scheme for a roll.

The device comprises a carriage 1 moving along the conveyor, a lever 2 on which the knotter 3 with a knife is fixed, a lever 4 with a movable roller 5 mechanisms for feeding the binding element, consisting of nz cartridges 6 for pro-rolls, rollers and correct rollers 7. Cassettes 6 and the correct rollers 7 are mounted on the bracket 8, which are turned by the counter-loads 9. The levers 2 and 4 are fixed on the carriage, have the rollers 10 and turn by the hydraulic cylinders P.

The device works as follows.

In the initial position, the levers 2 and 4 are in the divorced position. The Kronschteins 8 under the action of counter-loads 9 are separated to the sides of the conveyor, thus ensuring tension on the binding wire over the conveyor (see Fig. 4, I). When moving, the roll rolls over the wire and wraps it around a part of the circle (approximately 150 °) with a pre-adjusted force (| f). This force is regulated by pressing the correct rollers 7. When the wire is pulled through the correct rollers, it is straightened, and the brackets 8 are rotated to the conveyor axis by the tension of the wire.

When the roll reaches the dressing position, it is partially covered. After that, the hydraulic cylinders 11 are turned on, and the levers 2 and 4, set in motion by these hydraulic cylinders, are wrapped around the roll with wire

and bring together the wire sections under the twist (.) At the same time, the specified wire sections fall into the knots 3., which will twist them, and the knives of the knot knots cut the twist in half (). One half of the twisted turns remain on the roll, and the other half on the wire. Thereafter, all mechanisms are diluted to their original position, and the wire is pulled over the conveyor to tie the next roll.

To tie the coils of different diameters (1300-2300 mm), the carriage 1 is made movable along the conveyor. If, when mixed, levers 2 and 4 are not parallel, then carriage I will move along the conveyor towards the roll until the levers are parallel. For pressing the rear end of the roll, a movable roller 5 serves. Rollers 10 serve to interact with the levers 2 and 4 with the wire.

The proposed roll wrapper simplifies and reduces the cost of wrapping coils and

gives an economic effect of about 20 thousand PB. in year.
