Next, the usage method and operation (function) of the bag breaking device 1 and the separator 50 according to this embodiment will be described with reference to the drawings.

First, when an operation switch (not shown) is turned on, the first drive unit 3, the second drive unit 7, and the separator drive unit 72 are turned on.
Works. In this case, as shown in FIG. 5, the drive motor 21 of the first drive unit 3 alternately repeats the forward rotation operation and the reverse rotation operation at a preset time interval, and the drive motor 17 of the second drive unit 7 is , Forward rotation operation, ie, forward rotation only in the transfer direction.

Then, as shown in FIG. 2, the object M to be treated, which contains the garbage A ...
If it is put into the cutter housing 2 as it is, the object M to be processed falls onto the cutter unit 2 in the upper housing portion 9u. As a result, the object M is processed into a plurality of rotating disc-shaped blades 5

The inclinations of the disk-shaped blades 5 adjacent to each other are inclined by about 20 °, and the inclinations of the adjacent disk-shaped blades 5 are alternately opposite with respect to the axial direction. Further, the forward rotation and the reverse rotation are repeated alternately. The object M is quickly and surely broken.

On the other hand, the bag-breaking material Mm that has been crushed into small bags falls on the transfer unit 6 disposed below the cutter unit 2. As a result, the bag-breaking material Mm is transferred in the axial direction by the rotating transfer screw 8. When it reaches the discharge port 10, it falls from the discharge port 10. At this time, the discharge port 10 faces the supply port 51 of the separator 50, and
Since it is communicated with the inside of the drum, the bag-breaking material Mm is accommodated in the drum 52 from the outlet 10 as it is.

Inside the drum 52, the above-mentioned impeller wheel 58 is rotated at a rotational speed of about 600 [rpm], as shown in FIG.
Since it rotates in the direction of the middle arrow X, wind is generated inside the drum 52. In this case, the outside air is taken in through the air intake port 57, flows in the spiral direction by the straightening action of the straightening vanes 66, and is mainly discharged from the package dust discharge port 54 to the outside.

As a result, the bag-breaking material Mm supplied to the inside of the drum 52 is crushed by the rotating impeller wheel 58, and the relatively lightweight packaging dust As rides on the wind and is discharged from the packaging dust discharge port 54. . The discharged packaging waste As is collected by a collection container (not shown). On the other hand, food waste Aw that is relatively heavy and finely crushed
Are discharged (extruded) to the outside from the garbage discharge port 56 by the impeller rubber 62 provided at the tip of the rotating impeller 60. The discharged garbage Aw is collected by a collection container (not shown) arranged below the garbage discharge port 56. At this time, by arranging a plurality of collection containers side by side in the axial direction of the drum 52, it is possible to separate raw garbage that is easily separated from raw garbage that is difficult to separate.

According to the bag breaking apparatus 1 according to the present embodiment, the raw material A is housed in the bag B such as a relatively large vinyl bag and cannot be directly put into the separator 50. However, since the bag can be quickly and surely ruptured, the processing can be performed even with the relatively small separator 50, and as a result, the versatility of the separator 50 can be improved. In addition, the bag breaking device 1 includes a mounting portion 12 that is mounted on the supply port 51 of the separator 50.
As shown in FIG. 6, the existing separator 100 has been installed.
Can also be retrofitted. That is, as shown in the figure, the existing hopper 101 provided in the separator 100 may be removed and the bag breaking device 1 may be attached instead. On the other hand, the separator 100 is used as the separator body, and the bag breaking device 1 and the hopper 10 are connected.
If 1 can be selectively mounted as an option, the convenience can be further increased.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The detailed configuration, shape, material, parts, quantity, etc. can be arbitrarily changed, added, or deleted without departing from the scope of the present invention. For example, it does not matter whether the raw garbage A ... Is food. The bag breaking device 1 may be used as a single bag breaking device 1 by being supported by a plurality of legs. In this case, a container for hand-holding or a belt conveyor for automatic transportation can be arranged below the discharge port 10 and can be indirectly supplied to the separator 50 (100). further,
Although the first drive unit 3 and the second drive unit 7 are configured independently of each other, a single shared drive motor may be used and the rotation direction may be switched by a clutch or the like. On the other hand, the air intake port 57 can be changed to an auxiliary input port for inputting a small object to be processed, if necessary. Further, the separator 50 (100) and the bag breaking device 1 may of course be integrally manufactured from the beginning.
