Description

  The present invention relates to a configuration in which bags are continuously reduced and compressed to recycle used paper such as office paper, newspaper, magazines, and recycled paper.

Volumetric molded products that have been reduced in volume by compressing and deforming waste such as PET bottles and trays are used to prevent the molding from collapsing during transportation, spilling out parts that could not be integrated, and odors from waste. It is effective to pack the waste volume-reduced molded product. A waste plastic container packing device (Patent Document 1) is known as a device for reducing the volume of waste and packing it.
Further, there is known a processing apparatus (Patent Document 2) that processes a paper container whose expiration date has passed in a supermarket or the like, disassembles the contents and the pack or the packaging material, and extrudes and solidifies the pack and the packaging material.
Japanese Patent No. 3307628 Japanese Patent No. 2774468

The volume reduction method in Patent Document 1 described above is a method in which waste is compressed and deformed for each packing unit by a reciprocating compression device, transported to a bagging position and packed, and the device becomes complicated and large. The compression part needs to be composed of a robust member, and there is a problem that it becomes a large-sized device and the manufacturing cost increases.
In addition, the screw press method for reducing the volume by rotating the spiral body in Patent Document 2 has a relatively simple structure, but when a shredder piece of used paper or office paper is inserted, it is compressed in a cylindrical casing and the casing There was a problem that the outer periphery of the molded product was completely solidified by the frictional force with the inner wall and partially baked to make it unsuitable for production by a recycling factory or the like. Moreover, even if a storage bag for mobile transportation is simply attached to the discharge port of the cylindrical casing, uniform storage cannot be performed, or the inlet portion may be damaged if a pressing force is applied forcibly.

  In order to solve the above-mentioned problems, a storage connected by an input port, a conveying screw body, a cylindrical housing, a delivery port at the end of the cylindrical housing, and a mounting device having a support member that supports a storage bag at the delivery port. In a volume reduction device for waste paper or the like comprising a bag, the support member has a hole cross section substantially the same as the cross section of the cylindrical housing hole, the inlet portion of the storage bag is inserted into the inner surface, and the outer peripheral edge of the inlet portion is supported Thus, a volume reduction device for used paper or the like, which is characterized by being attached and detached, is provided.

  Further, in the volume reduction device for used paper or the like according to claim 1, the base portion of the support member also serves as a cylindrical housing, and a guide member whose end edge is widened is formed.

Since the storage bag mounting member is configured as described above, the pressing force of the screw body is applied to the entire inner wall of the support member near the entrance of the storage bag while the used paper is subjected to appropriate compression and adhesion in the cylindrical housing portion. Since it guides smoothly while receiving, the bag is filled uniformly. And when removing a storage bag, a volume-reducing material will not spill, if it draws on the inner wall of a support member.
In addition, since the compressed member is dispersed and thrown into the four sides by the diverging guide member, there is no extreme pressing force or biased back pressure on the bag inlet and shoulder, so the bag inlet is damaged. There is nothing to do.

  The configuration will be described below based on the drawings in which the present invention is implemented. FIG. 1 is a side external view of the present invention, FIG. 2 is a cross-sectional view in which a part of FIG. 1 is omitted, FIG. 3 is a front view of FIG. FIG. 5 is a side view of the storage bag attached with the attachment member, FIG. 6 is a front view of the attachment member attached, FIG. 7 is a view of the attachment member removed, and FIG. 9 is a side view showing another embodiment of the mounting member, FIG. 10 is a side view with the mounting member of FIG. 9 removed, FIG. 11 is a front view of FIG. 9, and FIG. 12 is a perspective view of the guide member. Is shown.

  1-3, A indicates a shredder, which has a conventionally known configuration. In this embodiment, the shredder is used for shredding used paper such as office paper, magazines, and newspapers, and has 11 crushing blades and 12 input conveyors. A crushing chamber 1 is provided. B denotes a volume reduction device, which is arranged in the lower part of the crushing chamber 1 so that a piece of paper shredded by the crushing blade 11 is guided to the inlet 8 of the volume reduction device and dropped. The volume reducing device B arranges the conveying screw body 6 along the receiving rod 2 in the horizontal direction.

  The conveying screw body 6 is rotated by the drive motor 3. Reference numeral 7 denotes a cylindrical housing, which is provided on the outer wall surface 18 of the receiving rod 2 and has a hole cross section through which the conveying screw body 6 can rotate. A storage bag 5 is connected to the delivery port side of the cylindrical housing 7. C denotes a mounting device for the storage bag 5 and includes a support member 17 and a lock lever 15 for fixing the support member 17. Reference numeral 13 denotes a guide member, which forms a part of the support member 17 and has a trumpet shape that spreads outward and is connected to the side surface of the cylindrical housing 7 described above.

  In the present embodiment, the cylindrical housing 7 and the guide member 13 constitute a support member 17. Reference numeral 9 denotes a frame for supporting the volume reduction device B, and the support wheels of 10 casters. In particular, in FIG. 2, the distal end portion of the conveying screw body 6 penetrates the outer wall surface 18 and projects partway through the cylindrical housing 7, and is configured to be somewhat shorter than the guide material 13.

  Next, the storage bag mounting device C will be described with reference to FIGS. The support member 17 is provided with a cylindrical housing 7 having the same hole along the rotational outer periphery of the conveying screw body 6 and a guide member 13 that spreads outward toward the outside. An annular flange is provided inside the cylindrical housing. 19 is fixed. Reference numeral 14 denotes a lateral pin, and a pair is provided toward the outside of the cylindrical housing 7. Reference numeral 15 denotes a lock lever which is fixed by operating the hook-shaped hook 16 to engage the lateral pin 14 of the support member 17. When detaching, the lock lever 15 is operated to release the hook 16 from the lateral pin 14 and the support member 17 is removed.

  FIG. 7 shows a state in which the support member 17 is detached from the outer wall surface 18 on the receiving rod 2 side. FIG. 8 shows that the inlet portion of the storage bag 5 is inserted inside the detached support member 17, the front end is brought into contact with the outer wall surface 18 of the flange 19, and the hook 16 is operated by operating the lock lever 15. After the hook 16 is read by the lock lever 15 again after being engaged with the lateral pin 14, it is fixed.

  Furthermore, another embodiment of the attachment device C will be described with reference to FIGS. FIG. 9 shows a state in which the mounting member C of another embodiment is fixed, and two notches 20 are formed on the flange 19 of the support member 13. On the other hand, sliding hooks 21 are provided on the outer wall surface 18 side so as to protrude in two places in the vertical direction, and correspond to the notches 20 on the flange 19 side. Accordingly, when the support member 17 is attached to the outer wall surface 18 and the notch 20 of the flange 19 is released in close contact with the sliding hook 21 and is closely contacted with each other as shown in FIGS. Bonded together.

  Next, the operation of the volume reduction device of this embodiment will be described mainly with reference to FIG. When used office paper, unnecessary magazines, waste paper, and the like are placed on the input conveyor 12 of the shredder A and sent, the paper is cut into narrow pieces by the crushing blade 11. The cut pieces are put into the loading port 8 of the volume reducing device B and fall to the conveying screw body 6. The conveying screw body 6 covered with the receiving rod 2 is compressed while rotating and moving the strip.

  The strip is appropriately compressed toward the inlet portion of the storage bag 5 connected to the delivery port of the cylindrical housing 7 portion, is pushed in close contact, and is further filled into the storage bag 5 via the guide material 13. At this time, since the inlet portion of the storage bag 5 is located inside the support member 17, the pushing force at the tip of the conveying screw body 6 is positioned outside the bag inlet portion, while the inner wall of the guide member 13 is Receive directly. Then, when the storage bag is filled with predetermined strips, the load current of the drive motor 3 is detected and the rotation is automatically stopped.

  Since the guide member 13 has a trumpet shape spreading toward the end, the compressed strips to be fed are smoothly accumulated while being distributed over the entire periphery. Accordingly, the storage bag is uniformly diffused and filled, and there is no longer a problem that the extreme pushing force is concentrated on the entrance portion or the shoulder portion to cause damage.

  Further, since the tip of the conveying screw body 6 protrudes inside the support member 17 so as to overlap in a side view, even when the supporting member 17 supporting the inlet portion of the storage bag 5 is detached, the conveying screw body 6 The tip blades act as a lid and there are few spills on the surface.

  In the present embodiment, the conveying screw body is installed in the horizontal direction. However, even if the conveying screw body is installed in the vertical direction and the storage bag is arranged at the lower part, the same effect is exhibited.
