SU1535374A3 - Device for removing binding wire from bales - Google Patents

Abstract

The apparatus provides one or two needles (5, 6; 5', 6') carried by a needle support 7 and movable thereon substantially parallel to one of the bale faces to traverse the latter, with the path travelled by the or one needle lying close to or just under said face to reach under the baling wires holding together the bale. The wires may be wound onto the needles on rotating the latter, the wires being severed by shears 21,22. The needle support is pivotable and provided with a stop 23 so that when the winding operation is over the resultant ball of wire is stripped by retraction of the needles passed the stop. In another embodiment (Figure 2), a magnet 32 is provided to raise the wires after severing to facilitate disposing of one of the needles therebeneath. The needles are held by upper and lower chucks 33,33' so that the needles can be shifted laterally together to clamp the wires therebetween. The shears may then be omitted or shearing elements provided on the needles (Figure 3). In another embodiment (Figure 6) a single needle is provided with a lateral lug 37' which clamps the severed wires on a rotatable needle receiving plate 9' on lowering of the needle. In another embodiment (Figure 4), lugs on opposed needles clamp the severed wires. A rake 41 (Figure 5) may be provided to strip waste from the wires. <IMAGE>

Description

31

The invention relates to the field of unpacking products, in particular, to devices for removing binding wires from a bale, mainly of metal.

The aim of the invention is to increase the reliability of operation.

The installation of the pins of the device for gripping the wires with the possibility of reciprocating movement and rotational movement increases the reliability of the capture and removal of wires.

Fig. 1 shows a device for removing binding wires from a bale, general view; Fig. 2 is the same with a magnet entering a wire grip attachment; on fig.Z - go, with the execution on one of the pins pointed edge; 4 shows a sharp edge; fig.Z - the same, with the offset of the pins one relative to another; figure 6 is the same, with the nl pin mounted; 7 - the same, with one pin of the device for gripping the wire

A device for removing binding wires from a bale comprises a feed conveyor I, a cutting mechanism and a device for gripping the wire including one 2 or 3 pin. The capturing device is equipped with a noBopoia mounted stand 4 with brackets 5. The pins 2 and 3 are mounted vertically in the brackets 5 with the possibility of reciprocating movement from the drive 6 to move at least half the bale thickness in the vertical with possible interaction rot with external or kicked - wire surface. Pins 2 and 3 can be installed parallel to each other, and the device for gripping the wire can be provided with a clamp 7 installed at the bottom of the device for pins 2 and 3 and a drive 8 for transmitting rotational motion to them. The actuator 6 of the reciprocating movement of the pins 2 and 3 vertically can be made hydraulic. The cutting mechanism can be made in the form of scissors 9. The device for gripping the wire is equipped with a magnet 10, preferably permanently mounted horizontally, and the edges 9 can be

mounted on the bracket 5 of the rack 4. A device for gripping wires can be equipped with clamping chucks 11, and the pins 2 and 3 are placed in the latter to move them against one another to clamp the wire. One of the pins 2 can be installed in the upper part of the rack, and the other pin 3 at the bottom, while their free ends are placed one towards the other, and the vertical axes are coaxial or offset one relative to the other by a distance equal to the diameter of the pin. The pins 2 and 3 can be fitted with clamping jaws 12 installed at their ends to clamp the wire. One of the pins may be equipped with a pointed edge located along the pin to interact with the other pin to create the counter support. A pin 13 can be attached to the pins to remove the paper.

The device works as follows

The bales of waste paper serves feed conveyor 1 to the working section of the device. The pins 2 and 3 are positioned above the pile with the aid of a rack 4. The scissors 9 are then activated and the wire from the side of the pile opposite the pin m is cut. Then the pins 2 and 3 by means of the actuator 6 are moved inside the bale from the outer and inner sides of the wire, after the switch the actuator 8 is turned on and the winding process begins, during which the wires are wound around the pins. When supplying a gripper with clamping chucks 1, the pins clamp the wire between themselves. This is good for tying cellulose bales from which it is impossible to dig them. In this case, after cutting the wire with scissors 9, it is lifted from the surface of the bale with a magnet 10, and then pins are made and rolled up.

When using clamping chucks 11, you can not use scissors, but when the pins rotate, break the wire and reel it,

When the axes of the pins 2 and 3 are displaced, one relative to the other, the wire is also clamped between the pins and then the wire rewind.

Comb 13 dumps paper from a wire.
