The work of removing the above-mentioned binding members is mainly done by
This is done just before feeding into the pulper.
It consists of the work of cutting the binding members and the work of collecting the binding members for separate disposal. Conventionally, a worker cuts each binding member such as a wire using a tool, resulting in extremely low work efficiency. Moreover, since the binding members spread around the package and fall, it takes time to pick them up. Furthermore, there is a problem in that the binding member may bounce during the cutting or collecting operation, requiring constant attention during the operation.
ところで、特開昭51−149148号公報には、梱包
体を結束している結束部材が切断された後に、そ
れを叉状爪体によつて巻き取り、除去できるよう
にした方法が記載されている。 By the way, Japanese Unexamined Patent Publication No. 149148/1983 describes a method in which, after the binding member binding the packages is cut, it can be removed by winding it up with a forked claw. There is.

て挿入するようにしている。そして、叉状爪体を
回転させて、マグネツトに吸着された結束部材を
巻き取り、塊状にまとめて廃棄することができる
ようになつている。 In this method, the package is cut from below with a cutter, and at the upper part opposite to the cutting, the top surface of the binding member is attracted by two spaced apart side-by-side magnets, and the binding member is removed. After the magnet is lifted away from the package, the fork-shaped claw body is inserted into a part of the binding member between the magnets by advancing in the horizontal direction. By rotating the prongs, the binding member attracted to the magnet can be wound up and disposed of in a lump.

とができない欠点がある。 However, when the binding member is separated from the package, it relies on the attraction force of the magnet, so there is a problem that the upward movement and tension state of the binding member become unstable. That is, a situation may occur in which the protruding position of the fork-like claw body to be inserted thereafter does not match the position of the binding member, and there is a possibility that the binding member may not be reliably wound up. Not only that, when the binding member is held between the tips of the fork-like claws formed in two prongs, if the two claws are in the upper and lower positions, the binding member cannot pass through, but the rotation of the member is stopped. There is a drawback that the posture of the prongs cannot always be reproduced.

うになつている。 By the way, the operation of the lifting cylinder 11, the cutting cylinder 13, and the pushing cylinder 16 is started and stopped when the movable parts of the package 2 and each device are moved to predetermined positions by a limit switch or a pressure switch (not shown). , and an abnormal rise in pressure in the hydraulic circuit, the respective electromagnetic switching valves are opened and closed automatically. An example of the hydraulic circuit is shown in FIG. To explain the operation of the lifting cylinder 11 as an example, the hydraulic oil from the pump 30 is transferred to the electromagnetic switching valve 3.
It passes through the first port 31a of 1A, extends the lifting cylinder 11, and raises the pronged claw body 10. When passing through the second port 31b, it is contracted and the fork-like claw body 10 is lowered to be inserted into the binding member 4. The cutting cylinder 13, the pushing cylinder 16, and the rotary motor 12 operate in the same manner. In such a circuit, the cutting cylinder 1
Pressure switches 32m and 32n are installed in the oil passages on the extension side between the cylinder 3 and the push cylinder 16. This is because if the package 2 becomes immobile for some reason, a large force will act between the package 2 and the package 2, so it is necessary to prevent cutting or pushing due to excessive force. Therefore, the pressure switch 32
With the operation of m and 32n, the electromagnetic switching valves 31B and 31C
is returning to neutrality. Further, the following considerations have been made to the circuit of the rotary motor 12. Although it is possible to wind up the binding member 4 by the forked claw body 10 by rotation in any direction, in this example, the first port 31 of the electromagnetic switching valve 31D
It is said that this is when it passes through e. At this time, the hydraulic oil supply path 33 is not provided with a throttle, so a large amount of hydraulic oil flows and the rotary motor 12 is driven at high speed. On the other hand, a throttle 35 is interposed in the hydraulic oil supply path 34 passing through the second port 31f, and the amount of hydraulic oil is suppressed. Therefore, the rotary motor 12 is driven slowly, and the position of the prong 10 is adjusted by slow rotation in the opposite direction.
At that time, if the electromagnetic switching valve 31D is returned to the neutral port by a signal from the rotation stop control device 29, the rotary motor 12 can be stopped immediately. Note that a check valve 36 is attached to the throttle 35 so that the flow of hydraulic oil during high-speed rotation is not obstructed.

Although the binding member 4 falls apart around the package 2,
On the winding device 6 side, the binding member 4 is supported by the roller 17 of the guide body 18, and crossing of the binding member 4 during winding by the forked claw body 10 is avoided. The extension of the cutting cylinder 13 is stopped, and the advancing of the cutting blade 9 is stopped.As the pushing pad 15 is moved back due to the contraction of the pushing cylinder 16, the cutting blade 9 is also moved back due to the contraction of the cutting cylinder 13. Simultaneously with the retraction of the cutting blade 9, the rotary motor 12 of the winding device 6 is rotated with a large amount of hydraulic oil via the first port 31e of the electromagnetic switching valve 31D, and the prongs 10 wind the binding member 4 at high speed. take. After being rotated for a predetermined period of time, the pronged claw body 1
0 is stopped when the electromagnetic switching valve 31D returns to neutral.
Since the binding member 4 is wound up while being guided by the roller 17 of the guide body 18, the binding member 4 is prevented from bouncing or becoming entangled. Finally, the lifting cylinder 11
extends and the fork-shaped claw body 10 is raised, and when the completion of the raising by the limit switch is detected, it is stopped there. In addition, at that time, the fork-shaped claw body 10 is installed in the auxiliary frame 37 attached to the winding support 23.

自動的に進めることができる。 In response to a signal from the limit switch that stops the raising of the pronged claw body 10, the electromagnetic switching valve 31D is set to the second port 31f. The rotary motor 12 begins to rotate slowly, and the rotational position of the pronged claw body 10 is changed. The rotation stop position detection device 27 detects the interruption of light by the protrusion 27a of the prong 10, and the rotation stop control device 29 outputs a neutral return command signal for the electromagnetic switching valve 31D. Since the forked claw body 10 rotates slowly, it immediately stops when the hydraulic oil is cut off, and the claw 10a can be placed in a position where it can be inserted into the binding member 4 of the package 2. By such an operation, the fork-shaped claw body 10 can be reliably inserted into the member 4 when unpacking the next packaged body 2. Therefore, there is no need for the operator to change the rotational position of the pronged claw body 10, and the unpacking work can proceed mechanically and automatically.
