An opening / closing door 8 that is opened and closed around one side (the right side in FIG. 2) is attached.

The collection container 5 is in the form of a rectangular box having an open upper surface, a collection bag 9 that can be in close contact with the inner surface thereof, and an angle-shaped member attached to the outer peripheral surface below the opening of the collection container 5. The opening portion 9a is folded and locked by the stopper member 5a, and is configured not to be drawn into the collection container 5 by compression. Further, a cover sheet that covers the opening may be attached to the collection container 5. Also, on the surface of the collection container 5,
Titanium oxide powder for deodorization is applied.

The positioning means 6 includes, for example, a guide rail 6b for guiding in and out, a positioning pin 6a which can be inserted into and removed from the pin holes of the bracket 5b of the collection container 5 and the bracket 6c of the apparatus main body 1, and a floating prevention (not shown). And a member. Further, a display device 10 such as a lamp, a box-type operation panel 11, and a waste plastic material inlet 12 are formed in the front of the machine room 3. An opening / closing lid 13 whose upper side is swingably supported via a hinge and is urged to close / close by a spring or its own weight hangs down from the input port 12, and the opening / closing lid 13 has the opening / closing lid 13 in a closed position. A lid lock device 15 for restricting the opening movement is provided. Then, the opening / closing lid 13, an inclined plate 14 a that also serves as an outer plate that inclines downward and downward, and a partition plate 14 b disposed at the front of the partition plate 2 are inserted into the rear side of the insertion port 12. A charging passage 14 for guiding the waste plastic material to the collection container 5 is formed. In addition, a dedicated loading plate 17 having a dedicated loading port 17a such as a PET bottle may be provided in front of the loading port 12, and as shown in FIGS. The shape of 17a can be changed.

The compression chamber 4 has guide rods 2 at four corners.
2 is provided with a pressing member 21 supported on the partition plate 2 via a guide cylinder 23 so as to be able to move up and down.
1 is formed in a size and a shape that can be pushed into the collection container 5 from the upper opening. At the upper part of the compression chamber 4, a pressure member drop prevention device 25 is provided, and a full detection sensor 16 including a light emitting and receiving device is provided. The fullness detection sensor 16 detects that the waste plastic material charged into the compression chamber 4 is full and interrupts the optical axis, and outputs it to the control device 35 to output a full display lamp or a full warning buzzer. Is configured to operate.

Further, a compression driving device 24 for driving the pressure member 21 up and down is disposed in the machine room 3. The compression driving device 24 is attached to the partition plate 2 and the piston rod 24c is connected to the pressure member. A plurality (a pair in the figure) of compression air cylinders 24a connected to the compressor 21 and an air pump unit 24b for supplying compressed air to these cylinders are provided. As shown in FIG. 4, the compression air cylinder 24a has a built-in stroke sensor 26. When the descending stroke is reduced to a predetermined value or less and reaches a predetermined compression ratio by operating air of a predetermined pressure, a compression operation is performed. Is completed.

When the stroke of “a” becomes smaller than a predetermined value and the stroke sensor 26 detects this, the control device 35 activates a compression end indicator lamp and a buzzer of the display device 10.

5. When the operator presses the loading / unloading operation button on the operation panel 11 or opens the opening / closing door 8, the built-in safety device is activated, and the lowering of the pressurizing member 21 due to malfunction is prevented. Then, the collection container 5 filled with the waste plastic material is taken out from the compression chamber 4, and is replaced with an empty collection container 5. The taken-out collection container 5 is transported to a processing plant, where the waste plastic material is taken out of the collection container 5 together with the collection bag 9 and processed.

Next, a case where the operation of the waste plastic volume reducing device is automated will be described. 1. The collection container 5 to which the collection bag 9 is attached is carried into the compression chamber 4 through the outlet 7 and is positioned by the positioning means 6. 2. When a user inputs waste plastic material such as a used plastic bottle from the input port 12, the input passage 14
Is charged into the collection container 5 via the

4. The opening operation of the worker opening the door 8 is detected by a sensor, and the built-in safety device prevents the pressing member 21 from lowering due to malfunction. Further, the collection container 5 is taken out from the compression chamber 4 and replaced with an empty collection container 5. According to the above embodiment, the compression driving device 2 is
Since the pressure member 21 is pushed into the collection container 5 by 4 to compress and reduce the volume of the waste plastic material, the compressed waste plastic material is taken out integrally with the collection container 5 and transported to the processing plant. The waste plastic material after volume reduction can be easily handled. In addition, it can be easily taken out from the collection container 5 by the collection bag 9.

Further, since the opening / closing lid 13 is locked by the lid locking device 15 while the pressing member 21 is descending, it is possible to prevent a user from injecting waste plastic material by mistake. Further, since the pressing member 21 is fixed at the raised position by the pressing member drop prevention device 25, it is possible to prevent the pressing member 21 from being erroneously lowered during the operation of taking out and taking in the collection container 5.
