Description

The invention relates to packaging technology and can be used primarily in the metallurgical industry for wrapping rolled steel packages.

The aim of the invention is to improve the reliability of the device by ensuring uniform compression of the branches of the wire before twisting, which is achieved by making one of the jaws of the pliers rotatable in the plane of compression.

FIG. 1 shows a device for wrapping wire packs in their initial position, general view; in fig. 2 - the same, 110 wrapping the package of the rolled stock, before starting to twist the ends of the wire into the knot; in fig. 3 shows the node I in FIG. 2; on f | ig. 4 shows section A-A in FIG. 2; in fig. 5 is a section BB in FIG. four; in fig. 6 and 7 are diagrams of the clamping of the branches of the wire with jaw pliers when changing the diameter of the wire.

The device for wrapping wire packs contains a frame 1 with a groove 2 and rollers 3, a gear rotor 4 of a C-shaped form with a cat 5 for wire 6 and tension rollers 7, a clip 8 for the end of the wire and a carriage 9, on

locks are folded. The carriage 9 rises to the working position, and the crossed branches 26 and 27 of the wire 6 are clamped with jaws 18 and 20 (Fig. 2).

5 The nominal location of the projection of the crossing point must coincide with the plane passing through the axis of rotation of the twisting head 10. In fact, this point deviates from the nominal location within the tolerance (Fig. 3),

10 and the branches 26 and 27 of the wire 6 intersect with the side edges of the jaws 18 and 20 at distances x and 6 from the axis of the hinge 17.

If both jaws are integral with the ticks levers 15 and 16, then when changing the wire diameter to one side or increasing from a certain average value, only one of the branches is clamped, since the working surfaces of the jaws are in this case angles of P or V to each other (Fig. 6 and 7).

20 In the device according to the invention, the sponge 18, turning relative to the axis 19 within the angle a, is self-adjusting according to the actual position of the legs 26 and 27 of the wire 6, and the clamping force is distributed to both branches of the wire. In the free sos | A sponge 18 torsion head is installed; it takes an arbitrary 30

10; 1l of wire, and a blade mechanism. The rotor 4 is rotated from the drive 12 through two bevel gears (not shown) and two qi, Lindrical gears 13

The carriage 9 is installed with the possibility of vertical movement in the direction of the lower 14 with the help of a drive (not shown). Twisting head 10 contains pincers consisting of two levers 15 and 16 interconnected by a hinge 17. Sponge 18 is freely mounted on axis 19. which is fixed to lever 15 perpendicular to H1 17. Second sponge 20 is integral with lever 16 .

On the surface of the lever 15, two supporting bevels 2 and 22, which cooperate with the plane 23 of the jaw 18, are made on the side of the swiveling jaw 18. In the head 10 clamped branches 26 and 27 of the wire 6.

The wire wrapping apparatus for rolling the packages works as follows.

Rental by piece or bundle is loaded into the groove 2 of frame 1 and a special device (not shown) is formed into a package 25 of circular cross section. An open wire rg wire 6, the margin of which is located on the coil 5, passes through the maze of tension rollers 7 and its end is held by the clamp 8 (Fig. 1).

After turning on the drive 12, the rotor 4 is 1 set to a predetermined number of 1 revolutions, 55 corresponding to the number of turns of the wire Ei bounding across the wire. After the rotor stops, the initial and final branches are in relation to the lever 15 within the angle a, which is determined by the interaction of the bevels 21 and 22 of the lever 15 with the plane 23 of the jaw 18.

After clamping the branches of the wire with the pliers of the twisting head, the clamp 8 releases the end of the wire, and the knife mechanism 11 cuts the second branch of the wire / yuki section of the wire from the coil. Next, the drive 24 is turned on and the jaws 18 and 20 twist the ends of the binding wire over the knot. Then the knife mechanism and the tongs of the torsion head are opened, and the carriage 9 is lowered to its original position. The rolled-up rolled bag 25 is removed in a known manner, for example, a colored bottle.

By reversing the rotor 4, the cut end of the wire extending from the labyrinth of the tension rollers 7 is inserted into the clamp 8 and fixed in it. The rotor 4 returns to its original position (Fig. 1), after which all the mechanisms of the device are in a state of readiness to perform the next binding cycle.

The distribution of efforts to clamp the binding wire with flares on both branches twisted into a knot allows simplifying the design and increasing the reliability of the operation of the twisting head.
