Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article volume reducer, that is, a volume reducer for compressing a volume of an article having a large volume such as a plastic bottle, and more particularly to packing an article having a compressed volume. The present invention relates to a transition plate arranged between the press chamber and the packing device so that the article can pass through when transported to the packing device.

[0002]

2. Description of the Related Art For example, a plastic container such as a PET bottle has a very large volume relative to its weight, and therefore, when the waste container is collected and recycled, the efficiency of transportation is extremely low. Therefore, it is necessary to carry it in a reduced volume. Various types of volume-reducing machines have been conventionally known, which reduce the volume of such waste plastic containers and the like, and then pack them for easy transportation.

No.), the plastic waste compression packing equipment
It has the following configuration. That is, the molding press device A
Is an insertion hole 1 for waste plastic in the upper plate 1a of the apparatus body 1.
f is perforated, and the receiving hopper 2 is arranged and fixed above it. A compression plate 5 driven by fluid cylinders 3 and 4 and a transfer plate 6 are slidably inserted in the apparatus main body 1, and the main body 1 includes a compression region 8 in which the compression plate 5 moves. It is divided into an area 9 in which the transfer plate 6 moves. In addition, the crimping and packing apparatus B has a box body 13 with both ends open.
A chuck device 14 for gripping the compressed waste plastic in the box body 13, a fluid pressure cylinder 15 for moving the chuck device 14 back and forth, a packing device 16 for crimp-packing the compressed waste plastic, and the like.

In the apparatus having the above structure, the waste plastic put into the receiving hopper 2 is supplied into the compression area 8 of the apparatus main body 1 through the insertion opening 1f. Then, the fluid pressure cylinder 3 is driven and the waste plastic is compressed by the compression plate 5. Further, at the same time when the transfer plate 6 is pushed in, the gate 7 of the carry-out port 1g is opened to move the compressed waste plastic into the box body 13. When the compressed waste plastic is sequentially pushed into the box body 13 by the transfer plate 6 and reaches the rear opening, the chuck device 14 causes the fluid pressure cylinder 15 to move.
By the above, one end of the waste plastic is pinched, and the waste plastic is retracted in synchronization with the advance of the transfer plate 6, and the waste plastic is moved into the packing device 16. At this time, the packing device 16 operates while synchronizing with the backward movement of the chuck device 14.

A second publication (Japanese Patent Laid-Open No. 7-15572)
The volume reduction apparatus for waste plastic containers described in No. 6) describes that "a passage 2 extending in the lateral direction is provided below the hopper 1, and a receiving frame 3 whose upper and lower ends are opened is moved left and right. The receiving frame 3 is connected to the first cylinder 6 of the double-acting cylinder device, and the seat 5 of the first cylinder 6 is connected to the second cylinder 4. The receiving frame 3 has a hopper extending rightward. A shutter 7 for opening and closing the mouth 1 is provided in series 1. Above the stop position A of the receiving frame 3 on the left side of the passage 2, a pusher 10 is provided to be moved up and down by a cylinder 11. Further on the left side of the passage 2. A pusher 20 is provided above the stop position B of the above to move up and down by a cylinder 21,
A pocket C for deposition is provided below it, a pusher 22 is provided to the right of the pocket C to move left and right by a cylinder 23, and a shutter 26 is moved vertically to the left of the pocket C by a cylinder 24. The packaging device 27 is provided on the left side of the packaging device 27.

In this waste plastic container volume reduction apparatus, waste plastic bottles 25 such as PET bottles loaded from the hopper 1 are stored in the receiving frame 3. Then the first
The cylinder 6 operates and the waste plastic bottle 25 in the receiving frame 3 comes to the stop position A. Next, the cylinder 11 is operated downward, and the pusher 10 moves the waste plastic bottle 25.
Is temporarily compressed and pressed. After that, the pusher 10 is further lowered to reduce the volume. Then, the second cylinder 4 is activated to move the waste plastic bottle 25 in the receiving frame 3 to the stop position B and drop the waste plastic bottle 25 in the receiving frame 3 into the pocket C. Next, the cylinder 21 is operated and the pusher 20 descends, and the waste plastic bottle 25 dropped in the pocket C is finally compressed and reduced in volume. By repeating the above operation, the stacked compressed waste plastic bottles 25 are sent to the packing device 27 and packed in a band.

[0007]

In any of the above-mentioned conventional apparatuses, waste plastic that has been compressed and reduced in volume is sent to the packing apparatus as it is, and a band or a film tape is wrapped around the packing apparatus for packing. When compressing and reducing the volume of plastic containers such as PET bottles, the body of the container is easily compressed, but the mouth is thick and hard, so it is not flatly compressed and broken into fragments. I will end up. If such fragments are brought into the packing device together with the compressed plastic, there is a problem that packaging failure may occur.

The present invention has been made to eliminate the above-mentioned drawbacks. Before sending the compressed and volume-reduced article to the packing means, foreign matters such as debris which cannot be compressed are removed to cause defective packing. It is an object of the present invention to provide a crossing plate of an article volume reducing machine capable of preventing the above.

[0009]

Means for Solving the Problems The cross plate of an article volume reducing machine according to the present invention comprises a supply means for supplying an article to a press chamber, a compression means for compressing the article supplied into the press chamber, and a compressed article. Provided in an article volume reducing machine provided with an extruding means for extruding an article through an openable / closable outlet gate provided on one side of the press chamber and a packaging means for packaging the extruded article with a binding band. The article extruded by the extruding means is disposed between the press chamber and the packing means so as to pass therethrough, and a space is provided for dropping the fragments discharged from the extruded article downward.

In the crossing plate of the article volume reducing machine, when the article supplied into the press chamber by the supplying means and compressed by the compressing means is extruded from the press chamber by the extruding means and moves toward the packing means, When passing over the transition plate, foreign matters such as debris of the hard part generated when compressed by the compression means in the press chamber fall down from the gap and are removed, so that it is not brought into the packing means. . Therefore, when the bundling is performed by the bundling means, the bundling means is not adversely affected, and there is no possibility of causing defective packaging.

As shown in FIG. 5, the transition plate 86 is in the shape of a ditch so that the debris and the like at the mouth of the plastic bottle 4 fall and are removed from the gap 86a of the drip while the bail 16 is moving. ing. A bail regulating plate 88 is arranged above the transition plate 86, and the bail 16 extruded from the press chamber 12 while banding is performed.
The upper surface of the is pressed so that it does not return from the compressed state.

Next, the operation of the article volume reducing machine 1 having the above structure will be described. First, an empty PET bottle 4 is manually inserted into the input hopper 2. In this embodiment, since the position of the input hopper 2 is low, it is possible to directly input the input hopper 2 manually without any additional input means, and the workability is very excellent. The PET bottles 4 accommodated in the input hopper 2 are sequentially conveyed to the upper main body hopper 8 by the traveling of the belt conveyor 6. When carrying the plastic bottle 4 into the main body hopper 8, the two-step shutter 10 closes the upstream introduction shutter 30 and
The entrance shutter 32 is open (state shown in FIG. 1).

When the plastic bottle 4 is carried into the main body hopper 2 and reaches the position of the supply completion detecting sensor 26, the belt conveyor 6 is stopped by a signal from the sensor 26. In this embodiment, the belt conveyor 6 stops when the plastic bottle 4 in the press chamber 12 is compressed into the main body hopper 8 in an amount compressed by one pressing step. After that, the introduction shutter 30 is opened and the bridge breaker 42 is operated by driving the geared motor 48. The plastic bottle 4 in the main body hopper 8 is connected to the supply passage 2
It is supplied into the press chamber 12 through the opening of the press chamber 12 via the nozzle 8. In this embodiment, since the introduction shutter 30 is opened and the bridge breaker 42 is rotated,
The plastic bottle 4 in the main body hopper 8 smoothly falls into the press chamber 12 without being in a bridge state, that is, in a state in which the bottles 4 are caught and entangled with each other.

After the plastic bottle 4 in the main body hopper 8 is supplied into the press chamber 12, the introduction shutter 30 is closed.
Then, the entrance shutter 32 is closed. When the plastic bottle 4 in the main body hopper 8 is supplied to the press chamber 12, the rotation of the bridge breaker 42 is also stopped. Also,
After the introduction shutter 30 is closed, the belt conveyor 6 is operated again to carry the PET bottle 4 from the lower loading hopper 2 to the upper main body hopper 8. The amount of plastic bottle 4 compressed in the press chamber 12 by one compression step
Is supplied and the inlet shutter 32 is closed, the hydraulic cylinder 14 for compressing the bottle is operated to operate the press head 5
Lower 2

When the press head 52 descends, first, the lower surface of the lower plate 58 hits the plastic bottle 4 and presses it. If the bottle 4 with the cap still attached when the plastic bottle 4 is loaded into the loading hopper 2 is crushed without smooth collapse when the press head 52 is lowered and compressed. In the apparatus of this embodiment, when there is the bottle 4 with a cap, the lower plate 58 flexes the spring 60 and relatively rises as the upper plate 54 of the press head 52 descends, and the punching pin The tip of 68 projects from the through hole 58a to the lower surface side of the lower plate 58. As a result, the bottle 4 with a cap is pierced and compressed smoothly.

Of the height detecting sensors 70, the uppermost first sensor 70a detects the ascent of the press head 52, and the lowermost fourth sensor 70d is the press head 52.
It is designed to detect the descending limit of, and while the PET bottle 4 is supplied from the main body hopper 8 into the press chamber 12,
The press head 52 is stopped at a position where the dog 72 (see FIG. 5) contacts the first sensor 70a. When the hydraulic cylinder 14 operates, the dog 72 causes the fourth sensor 7 to move.
The plastic bottle 4 is compressed by descending to a position in contact with 0d. After the completion of the first pressing step, the press head 52 again rises to a height at which the first sensor 70a is turned on. After that, the entrance shutter 32 is opened and the two-step shutter 10 returns to the state of FIG.

At the time when the first pressing step is finished, the PET bottle 4 for the next one time has already been carried into the main body hopper 8 by the belt conveyor 6, and the introduction shutter 30 is opened again to open the main body. The PET bottle 4 in the hopper 8 is supplied to the press chamber 12. Then, the same operation as described above is sequentially performed to perform the second pressing step.
After that, the same operation is repeated to perform a plurality of pressing steps. While repeating a plurality of presses, the introduction shutter 30
To open the plastic bottle 4 in the main body hopper 8 and press room 1
2 when supplied to the press chamber 12
There is a case where the inside of the supply passage 28 is stopped without entering the inside. Since such a bottle 4 is pushed back into the main body hopper 8 when the opened introduction shutter 30 is rotated in the opposite direction to be closed, the bottles 4 are bitten when the inlet shutter 32 is subsequently closed. Never.

It is confirmed by the height detecting sensor 70 that the final pressing step is performed while the pressing is repeated a plurality of times. That is, during the normal pressing process, the press head 52 moves up and down between the position where the uppermost first sensor 70a is turned on and the position where the lowermost fourth sensor 70d is turned on. As the height of the pressed bottle 4 increases, the lower position of the press head 52 increases. And press head 52
When the fourth sensor 70d does not turn on even when is lowered, the press head 52 is returned to the first sensor 70a after a certain time has passed in that state. When further pressing is performed to raise the height of the bail 16 and the press head 52 descends, the third sensor 70c third from the top does not turn on and a certain time has passed, that is, the dog 7
2 is the second sensor 70b and the third sensor 70 which are second from the top
When it is stopped during c, it is confirmed that it is the final pressing step, and the press head 52 is moved to the second sensor 7
0b is raised to a height at which it is turned on (state in FIG. 2).

When the press head 52 is lowered to compress the PET bottle 4, as described above, the lower plate 58 bends the spring 60 relative to the upper plate 54 and ascends, and the punching pin 68 is moved. Lower plate 58
It projects more downward than. Therefore, the veil 16 cannot be discharged from the press chamber 12 in this state. Therefore, after the pressing is completed, the hydraulic cylinder 14 is operated to raise the press head 52 to a height at which the second sensor 70b is turned on. Then, the lower plate 58
Is pushed down by the spring 60 and the piercing pin 68 slides out of the lower plate 58 and away from the bail 16, allowing the bail 16 to move. Further, when the press head 52 is raised to a height at which the second sensor 70b is turned on, the lower plate 58
Is located at a height slightly lower than the bail restriction plate 88 provided above the transition plate 86 outside the press chamber 12 (see FIG. 2).

When the pressing process is completed as described above, the outlet gate cylinder 76 is then actuated to raise the outlet gate 78 and open the discharge port 74 of the press chamber 12. Then, the bale pushing cylinder 18 is operated to push the bail 16 by the pushing plate 84 to the banding machine 20.
In the direction of. For example, when three bands 22 are hung on the outer periphery of the bail 16, the bail extrusion cylinder 18
By the first operation, the bail 16 is pushed out until the position ¼ from the head (right end in FIG. 2) comes to the position of the band 22 of the band hanging machine 20. Extruded bale 16
Moves on a grid-like bridge plate 86 and advances to a predetermined position. When the mouth portion of the PET bottle 4 or the broken pieces of the cap are mixed in the bail 16, the pieces are dropped and removed from the gap 86a of the drain board 86. The body of the PET bottle 4 has a thin plate shape and can be easily compressed by pressing, but since the mouth or the cap is hard, it is not compressed even when pressed and is broken into fragments. If these pieces are brought into the banding machine 20, problems such as defective packaging may occur. As a result, the banding machine 20 is free from the risk of defective packaging or the like.

After performing the first banding at the above-mentioned position, the bale pushing cylinder 18 is operated again to move the bail 16 so that the substantially center of the bail 16 comes to the position of the band 20, and the second banding is performed. . In addition, veil 1
6 is moved by 1/4 and the third banding is performed to complete the packing work. In this way, the press head 52
Lower plate 58 and bail control plate 8 outside the press chamber 12
While holding down the upper surface of the bale 16 by 8, move
Since the banding is performed, the bail 16 does not return due to the spring back, and its height becomes uniform. The bale 16 for which the packing work has been completed is completely pushed out from the press chamber 12 by the pushing cylinder 18 and discharged. After the bale 16 is discharged from the press chamber 12, the pushing plate 84 of the bale pushing cylinder 18 is retracted, and the outlet gate 78 is lowered by the outlet gate cylinder 76. Furthermore, the compression hydraulic cylinder 14
The press head 52 is raised by the operation of, and the supply of the PET bottle 4 from the main body hopper 8 into the press chamber 12 is restarted.

In the above embodiment, the case of compressing and reducing the volume of the PET bottle 4 has been described, but the present invention is not limited to the PET bottle 4, and other items such as empty cans and paper packs are compressed and reduced in volume. Needless to say, it can also be applied to packaging. Further, the transition plate 86 that supports the lower surface side of the bail 16 that is discharged from the press chamber 12 and is sent to the banding machine 20 has the shape of a sludge in the above embodiment,
The shape is not limited to the drainboard shape, and any material may be used as long as it has a space for the broken pieces and the like at the mouth of the bottle to drop.
