Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for processing a compressed waste paper block tightening wire A. for efficiently processing the wire tightening the compressed waste paper block.

[Conventional technology]

After waste paper such as old newspapers and old magazines is collected by a collection company, it is compressed into a rectangular block by a compressor, and then tightened into a solid state with multiple wire hooks. Sent to a remanufacturer. At the recycling plant, this compressed waste paper block is crushed by a crusher, but as a pre-processing step, it is essential to remove the wires from the compressed waste paper block.

Conventionally, this wire removal work was performed manually, and the wires were cut by an operator using a cutter. However, since the wires are deeply embedded inside the compressed waste paper, the cutting operation is time-consuming, and there are also safety problems as injuries are common.

In order to solve these problems, the Special Publication Publication No. 62-2697
An automatic wire cutting device as shown in Publication No. 6 has been proposed.

This device consists of a tooth plate with pointed teeth arranged in a row, another tooth plate whose teeth are in close contact with this tooth plate and reciprocate in the longitudinal direction of this tooth plate, and both of these plates. tooth subplate teeth,
This device has a pressing mechanism that presses the tooth tips into the compressed waste paper and cuts the wire that binds the compressed waste paper.The sharp tooth tips of the toothed plate enter the compressed waste paper and then rub together to release the wire. It is designed to be cut.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional automatic wire cutting device, when processing the wire, it is necessary to advance the toothed plate into the compressed waste paper, and the depth of the wire cutting into the compressed waste paper block is considerable. Therefore, a considerable amount of pressing force must be applied to the toothed plate, which may result in incomplete cutting, and waste paper is also rubbed together with the wire during cutting, creating a large amount of debris and creating a poor work environment. There was a problem in that it significantly worsened the condition.

An object of the present invention is to eliminate the drawbacks of the conventional tightening wire processing method described above, and to partially expose the wires wedged inside the compressed waste paper block on the surface of the compressed waste paper block. To provide a method for processing compressed waste paper tightening wire, which adds a bending step of bending into an arched shape to enable smooth cutting with a cutter and also facilitates processing of the wire after cutting. .

[Means for solving problems]

The structure of the present invention for achieving the above object will be described in detail.
A folding process in which a compressed waste paper block tightened by multiple wires is bent into an arched shape on a work table consisting of a conveyor, etc., and after the bending process is completed, the wires exposed on the concave side of the compressed waste paper block are moved to a presser. It is characterized by having a wire gripping step in which the wire is gripped by a dual-purpose wire clamper, and a cutting step in which a cutter is driven into the center of the protruding side of the compressed waste paper block to cut the wire tightening the compressed waste paper block after the wire gripping step is completed. This is a method for processing compressed waste paper tightening wires, and in the folding process, the front side of the compressed waste paper block on the work table is pressed against the center of the compressed waste paper block, which also serves as a presser, and prepared on the back side of the compressed waste paper block. It can be bent into an arched shape along a certain bending guide plate.

In this manner, the compressed waste paper block is bent into an arched shape during the bending process, so that the wire is exposed in the recess formed by the bending. When the exposed wire is grabbed by a wire clamper that also serves as a pusher and the wire is slightly pulled toward the side opposite to the protruding side of the compressed waste paper block, tension is applied to the wire on the protruding side. In this state, a cutter is driven into the center of the protruding side of the compressed waste paper block to cut the wire tightening the compressed waste paper block, and on the concave side of the compressed waste paper block, the wire also serves as a pusher. Since the wire is held by the clamper, there is no fear that the wire will fly away during cutting, making it much easier to dispose of the wire after cutting.

5 is a wire clamper that also serves as a presser and is installed on one side of the compressed waste paper block l at the bending position set on the work table 3, and 5 is a hydraulic cylinder that is attached to the upper and lower ends of this wire clamper that also serves as a presser 4, respectively. Yes, when the piston loft of the hydraulic cylinder 5 expands, the wire clamper 4 that also serves as a pusher moves back away from the work table 3, and when the piston loft contracts, the wire clamper 4 that also serves as a pusher moves forward toward the work table 3. . 6
7 is a set of two fixed claws arranged side by side on the work table 3 side of the wire clamper 4 which also serves as a presser; 7 is a movable claw slidably arranged between the fixed claws 6°6; and 8 is a movable claw. A clamp cylinder built into the casing of the wire clamper 40 which also serves as a presser acts to move the movable claw 7 up and down by the expansion and contraction of the piston loft.

Reference numeral 9 denotes a bending guide member disposed opposite the wire clamper 4 which also serves as a presser; in the illustrated embodiment, the left and right guide plates are separated at the center; It is also possible to make the cutter insertion hole, which will be described later, open only in the intermediate part thereof.

14 is a moving side delivery roller, and both rollers 13
．． 14 has a structure in which the circumferential surface thereof is uneven along the longitudinal direction so that they can mesh with each other. 1
Reference numeral 5 denotes a hydraulic cylinder for moving the moving-side delivery roller 14, and 16 a guide member for the moving-side delivery roller 14. When the hydraulic cylinder 15 extends, the moving-side delivery roller 14 is guided by the guide member 16. It moves to the stationary side delivery roller 13, and the circumferential surfaces thereof mesh with each other.

Reference numeral 17 designates a fixed blade disposed near the feed rollers 13 and 14, 18 a movable blade that is moved back and forth by a hydraulic cylinder 19, and 20 a guide post for the movable blade 18.

In the embodiment shown in FIG. 9, the bending guide member 9 is fixed with a certain tapered surface.
In order to bend both wings toward the work table 3 side, a driving device such as a hydraulic cylinder may be disposed on the back surface of the left and right guide plates.

Next, an example of implementing the method of the present invention using such an apparatus will be described.

First, the compressed waste paper block 1 is placed on the work table 3 so that the width direction of the work table 3 and the stacking direction of the compressed waste paper block 1 are the same, and the compressed waste paper block 1 is placed at a bending position set on a conveyor or the like. When this point is reached, the movement of the compressed waste paper block 1 is stopped by detection by a limit switch (not shown) or the like (FIG. 1).

Next, at this stop position, the hydraulic cylinder 5 is operated to move the wire clamper 4 which also serves as a pusher in the direction of the arrow in FIG. Then, the tips of the wire clamper 4 that also serves as a pusher, that is, the tips of the fixed claw 6 and the movable claw 7, come into contact with approximately the center of one side of the compressed waste paper block 1, and when they are further advanced, they touch the opposite side of the compressed waste paper block 1. comes into contact with the folding guide member 9, and is guided by the tapered surface of the folding guide member 9, so that the entire compressed waste paper block 1 is bent into an arched shape (FIG. 2). This bending process exposes the wire 2 that has been bitten into the recess 2I of the compressed waste paper block 1. However, since the wire clamper 4 which also serves as a presser is in contact with the center of the recess 21 at a position 1ξ, the tension of the exposed wire 2 is suppressed by the wire clamper 4 which also serves as a presser. .

Next, as shown in FIG. 3, the wire clamper 4 which also serves as a pusher is slightly moved back away from the compressed waste paper block l. Then, the wire 2 under tension is also completely pulled away from the compressed waste paper block 1, and in this state, the wire 2 is gripped by the interaction between the fixed claw 6 and the movable claw 7 built into the wire clamper 4 which also serves as a presser (the third figure).

After confirming that the wire clamper 4 that also serves as a presser has clamped the wire 2, the wire clamper 4 that also serves as a presser is moved further away from the compressed waste paper block 1, and
Apply tension to the wire 2 of the 9 bending guide members (
Figure 4).

Note that the compressed waste paper block l itself has considerable gravity, and its stacking direction is the same as the width direction of the work table 3 consisting of a conveyor etc. Even when the pressing force is released, there is no fear that the compressed waste paper block l bent into an arched shape will return to its original state.

Next, in this state, the cutter hydraulic cylinder 1 is operated, and the cutter 10 is driven into the center of the protruding side 22 of the compressed waste paper block I (Fig. 5), that is, the wire 2
After electrically confirming that the wire clamper 4, which also serves as a presser and is still gripped, has stopped in the state shown in Fig. 4, the hydraulic cylinder 11 for advancing the cutter 10 is driven, and the cutter 10 is moved forward. Compressed waste paper block 1
The protruding side 22 of is driven into the center, but as mentioned above, it protrudes! Since the wire 2 at 22 is under considerable tension, it is easily cut by the entry of the cutter IO.

Note that the cutter IO is located on the protruding side 22 of the compressed waste paper block 1.
By entering the compressed waste paper block 1, the protruding part of the compressed waste paper block 1 is pushed back toward the recess 21 side, and the compressed waste paper block 1 in the folded state may return to its pre-folding state.

After confirming that the wire 2 has been cut, the piston rod of the cutter hydraulic cylinder 11 is moved back, and a wire clamper 4 that also serves as a pusher is placed near the work table 3 in order to pull out the wire 2 from the compressed waste paper block 1. Retract the feed rollers 13 and 14 to the rear position (
Figure 6). After retracting to a predetermined position, move the movable delivery roller 14 and move the fixed delivery roller 13.
The wire 2 is held down between the two rollers 13 and 14, and then the wire 2 is cut by the interaction of the fixed blade 17 and the movable blade 18 (FIG. 7).

Next, the feed rollers I3 and 14 are rotated to feed out the wire 2 by a predetermined amount, and the fixed blade 17 and the movable blade 1
8, the wire 2 is cut, and this operation is repeated thereafter to complete the processing of the wire 2 (FIG. 8).

In the method of the present invention, the wires that are deeply wedged inside the compressed waste paper block are partially exposed by bending the compressed waste paper block into an arched shape so that they can be easily clamped. By slightly pulling the clamping part, tension is applied to the opposite side of the compressed waste paper block to facilitate cutting with a cutter, and each operation is performed automatically and continuously according to a predetermined schedule. It is something that can be done.

[Effects of the Invention] Therefore, according to the method of the present invention, when cutting, there is no fear that the waste paper is rubbed together with the wire as in the conventional method, and the generation of mm can be suppressed, which has a great effect on improving the working environment. be.

Further, since the wire on the side where the cutter is driven is under tension, the cutting is performed perfectly, and problems with incomplete cutting can be prevented.

Furthermore, since the wire after cutting is in a state of being clamped by the wire clamper which also serves as a presser, subsequent processing of the wire becomes much easier.
