Abstract

PROBLEM TO BE SOLVED: To change only an intermediate ring when a cutting blade is not usable because of wear by providing with the cutting blade performing cutting in cooperation with one edge part of a compressing member and providing with an intermediate ring between a first inside tubular body and a second inside tubular body. SOLUTION: The waste is sent into the inside tubular body 19, compressed with the compressing member 47, further slidden in the left direction, and compressed and solidified between a gate and the compressing member. When the left edge part of the compressing member 47 passes the cutting blade 73, the waste is cut with both cooperations. The compressing member 47 is transferred in the right direction to release the compressing condition, and the gate is opened upward to push out the solidified waste from the inside tubular body 19. When wear such as making the cutting blade 73 not usable is generated, the first inside tubular body 67 and the intermediate ring 71 are taken out from an outside tubular body 15, changed with another intermediate ring 71 and incorporated into the outside tubular body 15. The intermediate ring 71 only is changed for changing the cutting blade 73, whereby cost is reduced.

TECHNICAL FIELD The present invention relates to, for example, metal chips,
The present invention relates to a waste compression / solidification device that compresses and solidifies waste such as chips and paper waste.

[0002]

2. Description of the Related Art As a conventional waste compression and solidification apparatus, there is one shown in Japanese Utility Model Laid-Open No. 7-33490, and this prior art will be briefly described below.

The waste compression and solidification device is based on a main body frame, and a hopper capable of accommodating waste is provided on the main body frame, and a carry-out port is provided on the bottom side of the hopper. . Further, an outer pipe body extending in the left-right direction is provided below the hopper in the main body frame, and the outer pipe body has an outer supply port communicating with the carry-out port. An inner tube is provided in the outer tube so as to be movable in the left-right direction by a slight amount, and the inner tube is biased to the left by a spring. The inner pipe body has an inner supply port communicating with the outer supply port, and a right side edge of the inner supply port is integrally provided with a cutting tooth for cutting with a left side edge of a compression member described later. Be prepared for.

Since waste is fed from the carry-out port of the hopper into the inner pipe through the outer supply port and the inner supply port,
Inside the hopper, a screw conveyor is provided so as to be rotatable by driving a feed motor. Further, in order to compress the waste sent into the inner tube, a compression member is provided in the inner tube so as to be slidable in the left-right direction (longitudinal direction of the tube) by the operation of the compression cylinder. Further, on the left side of the hopper, a gate that opens and closes the left opening in the inner tube is provided so as to be movable in the vertical direction by the operation of the opening and closing cylinder.

Therefore, after the waste is stored in the hopper, the screw conveyor is rotated by the drive of the feed motor, so that the waste is transferred from the hopper carry-out port to the inner pipe through the outer supply port and the inner supply port. Send in.
Before the waste is sent into the inner pipe, the gate is moved downward by the operation of the opening / closing cylinder so that the gate closes the opening on the left side of the inner pipe.

After the waste is fed into the inner pipe, the compression member is operated to slide the compression member in the left direction (direction of compression), whereby the compression member compresses the waste from the left direction, and The waste is compressed and solidified between the gate and the compression member by sliding the compression member to the left. Here, when the waste (for example, long metal chips) straddles the inner tube and the hopper (outer supply port), the compression member moves to the left and the left edge of the compression member. The waste is cut by the cooperation of the left edge of the compression member and the cutting tooth as the part passes through the cutting tooth.

After the waste is compressed and solidified, the compression cylinder is operated to move the compression member to the right to release the compression state by the compression member. Next, the gate is moved upward by the operation of the opening / closing cylinder, and the opening on the left side of the inner tube is opened by the gate. Then, by operating the compression cylinder to move the compression member to the left again, the compressed and solidified waste is extruded from the inner pipe body through the opening.

[0008]

However, if the above-mentioned operation is performed a plurality of times, the cutting teeth may be worn to the extent that they cannot be used. In this case, since the cutting teeth are formed integrally with the inner tube body, it is necessary to replace the entire inner tube body with another inner tube body, which causes a problem of high cost.

Further, since the inner pipe is movable in the left-right direction, when the waste is compressed and solidified between the gate and the compression member, the high-pressure waste causes the inner pipe to resist the biasing force of the spring. Then, the waste is compressed and solidified under the condition that it is provided with the flange by moving it to the right and entering it between the gate and the first inner tube. Therefore, even if the compressed state by the compression member is released, the flange is urged to the left by the urging force of the spring, and the flange further presses the gate to the left,
There is a problem that it is difficult to move the gate upward (opening direction).

[0010]

In order to solve the problems of the prior art as described above, in the present invention, as a first means, a hopper capable of accommodating waste is provided, and is carried to the bottom side of this hopper.

An inner pipe body having a supply port (the cross-sectional shape may be either circular or rectangular) is provided, and the waste is sent from the carry-out port of the hopper into the inner pipe body through the outer supply port and the inner supply port. Therefore, a screw conveyor for feeding is provided rotatably by the drive of the feed motor inside the hopper, and the waste fed into the inner tube is compressed, so that the inside of the inner tube (corresponding to the cross-sectional shape of the inner tube Press the compression member (in shape) An opening / closing operation device is provided that is slidable in the longitudinal direction of the tubular body by the operation of the operation device, opens and closes an opening on one side of the inner tube, and has an opening / closing operation device that moves the gate in the opening / closing direction.

Also, in the case where the constituent features of the seventh means are provided, even if the spiral-shaped waste is hooked on the hooking portion and securely entangled with the feed screw conveyor, Can be delivered into the tube.
Before the waste is sent into the inner pipe, the gate is moved in the closing direction by the operation of the opening / closing device so that the gate closes the opening on one side of the inner pipe.

After the waste has been fed into the inner pipe, the compression member is slid in one direction (the direction of compression) by the operation of the compression actuator, whereby the compression member compresses the waste from one direction, Further, by sliding the compression member in one direction, the waste is compressed and solidified between the gate and the compression member.

Next, the gate is moved in the opening direction by the operation of the opening / closing actuator, and the opening on one side of the inner tube is opened by the gate. At this time, the compressed solidified waste does not push the gate in one direction, and the movement of the gate is not hindered. Then, the compression member is moved again in one direction by the operation of the compression actuator, so that the waste solidified by compression is extruded from the inner pipe body through the opening.

By repeating the above operation a plurality of times,
A plurality of wastes that have been compressed and solidified can be extruded from the inner tube, but if the cutting teeth are worn to the extent that they cannot be used, the following operations are performed.

That is, the first inner tube is detached from the outer tube and taken out from the outer tube, and the intermediate ring is taken out from the outer tube. Then, the intermediate ring is replaced with another intermediate ring.

It is possible to suppress the entry between the first inner tube bodies 67.

After the waste is compressed and solidified, the compression cylinder 51 is actuated to move the compression member 47 to the right to release the compression state of the compression member 47. Next, the opening / closing cylinder 61 is operated to move the gate upward so that the gate 57 opens the left opening of the inner tubular body 19.

Can be reduced.

Further, by fixing the first inner tube body 67 to the left side portion of the outer tube body 15, the gate 57 is pushed leftward by the compressed and solidified waste as in the prior art. Therefore, the gate 57 can be easily moved upward to open.

Further, since the feed screw conveyor 25 can be rotated under the condition that the waste is drawn toward the carry-out port 11, it is possible to store a large amount of waste in the hopper 9. Also, the waste can be sent from the carry-out port 11 into the inner pipe body 19 through the outer supply port 17 and the inner supply port 21, and the work efficiency is improved. On the other hand, since the waste attraction state is released after the waste is once attracted to the carry-out port 11 side, clogging of the waste in the carry-out port 11 can be avoided.

Further, even spiral waste can be sent into the inner pipe body 19 under the condition that it is hooked on the hooking portion 33 and securely entangled with the feed screw conveyor 25, Work efficiency is further improved.

[0046]

As can be understood from the above description of the embodiments, according to the invention described in any one of claims 1 to 7, the cutting teeth are worn to the extent that they cannot be used.

Particularly, according to the invention of any one of claims 5 to 7, the cutting resistance is reduced by forming the cutting teeth into a continuous shape extending in the longitudinal direction of the tubular body. Therefore, the life of the cutting teeth can be improved and the cost can be further reduced.

Since the first inner tube is fixed to one side of the outer tube, the gate is not pressed in one direction by the waste solidified by compression as in the prior art. The gate can be easily moved in the opening direction.

Further, according to the invention of claim 6 or 7, since the screw conveyor for feeding can be rotated under the condition that the waste is drawn to the outlet side, a large amount of waste is discarded. Even when the product is stored in the hopper, the waste can be sufficiently sent from the carry-out port into the inner pipe through the outer supply port and the inner supply port, and the work efficiency is improved. On the other hand, since the waste attraction state is canceled after the waste is temporarily attracted to the carry-out port side, it is possible to avoid clogging of the waste in the carry-out port.

According to the seventh aspect of the present invention, even spiral waste is sent into the inner pipe body under the condition that it is hooked on the hooking portion and securely entangled with the screw conveyor for feeding. The work efficiency can be further improved.
