Description

Machines for baling and wrapping bundles of metal in three or four places are known.

Also known machines for rolling rolled products with simultaneous hanging tags. Such machines contain double-turn wiring, a drive and a mortar-cutting mechanism.

The proposed machine is different in that. that in one of the channels of the double-turn wiring, the reversible feed rollers were cut, and the ends of the wire were clamped with two hammer-shaped levers driven by pneumatic cylinders. This provides a consistent feed and tightening of the binding wire.

FIG. 1 shows the kinematic scheme of the proposed machine; in fig. 2 - in a die cutting head.

The bundle to be rolled rolled is delivered by a bridge crane to the bottom of the pocket, where four machines are installed to cover the required distance between the ties.

The wrapping wire riot is on the adaptive device / which is equipped with a brake 2, preventing them from breaking up the wire in the riot when the feeding mechanism is stopped. The wire from the riot is driven by the driving rollers 3 but to the first channel 4 of double-wiring, the wire is pressed to the driving rollers 3 by the idle rollers 5 and the spring b through the lever system. The rollers are driven all the way from the electric motor 7 through a gearbox and a parasitic gear. At the end of the nerve coil of the wire, pnevmilders 5n are turned on by means of the mechanism 9, idle rollers 10 are inserted into the bypass wiring. These rollers attach the wire to the drive rollers 11, which feed it into the second channel 12 of the double-core

wiring. The rollers // are driven by an electric motor 7.

At the end of the second turn, the front end of the wire enters the groove in the die head / 5 and is clamped by the lever 14 (see

fng 2). At the same time, motor 7 is reversed and wire wrapping starts around the bundle of rolled metal.

The rollers // tighten the second turn, and the rollers 3 transfer the excess wire to the bung.

When the second turn is wrapped around the pack, the load on the motor 7 increases, and it stops, remaining under current.

The motor control shaft has a speed control relay (not shown in the drawing),

which sends a signal to the output of the idle rollers 10 from the bypass wiring. The motor picks up speed, the second coil is pulled up and the nerve coil is tightened with rollers 3.
