Description

[Technical field]

[0001] This invention relates to a compression and cutting device that compresses and reduces the volume of recyclable waste such as waste plastic and paper, and cuts them. [Background technology]

[0002] Efforts are being made to recycle waste generated from homes and factories into new resources. For example, collected waste plastic is washed and separated, then crushed or compressed, stored, and shipped as fuel for power generation facilities and waste incineration facilities, or as a raw material for cement. It is also processed into pellets and shipped as a raw material for recycled plastic products such as new electric wire coatings, home appliance bodies, and sheet films.

[0003] Known devices for compressing waste plastics are disclosed in Japanese Patent Application Laid-Open Nos. 55-150323, 59-185624, 7-315327, and 2002-321096. In these devices, waste plastics are put into a hopper, and the waste plastics in the compression chamber are compressed with a pressure plate to reduce the volume. The waste plastics compressed into blocks are bound with tape or PP bands, or the surface layer is heated and melted to maintain the compressed shape. [Prior art documents] [Patent documents]

BEST MODE FOR CARRYING OUT THEINVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In Fig. 1, reference symbol S denotes a compression cutting device.

[0015] The compression and cutting device S is a device that compresses, cuts, and roughly crushes recyclable waste such as plastics and paper. As shown in Figures 1 to 3, its basic configuration includes a device main body 10, an upper hopper 20, a pressure plate 30 with a cylinder 31, and a cutting processing section 40.

[0016] The device main body 10 has a box-shaped casing 11 that is long from front to back, and a compression treatment chamber 12 for compressing waste h (see FIG. 5) is provided in an internal front chamber of the casing 11. An opening (communication port) 13 that opens into the compression treatment chamber 12 is provided on the top surface of the casing 11. An opening (discharge port) 14 that opens into the compression treatment chamber 12 is provided on the front surface of the casing 11.

[0017] The upper hopper 20 is for loading waste from above and has an inlet 21 at the top. Waste h (see Figure 5) loaded into the inlet 21 falls through the opening 13 into the compression treatment chamber 12 and accumulates therein.

[0018] The pressing plate 30 advances within the compression chamber 12 by forward movement due to the operation of the cylinder 31, compressing the waste h within the compression chamber 12 and at the same time pushing out the compressed waste hc (hereinafter referred to as compressed waste hc) to the cutting processing section 40 arranged at the opening 14 facing the pressing plate 20 (see FIG. 6). The pressing plate 30 is arranged in the rear chamber of the casing 11 facing the compression chamber 12, and advances within the compression chamber 12 from the return position to the position of the opening 14 by the operation of the cylinder 31, and also retreats from the advance position to the initial return position.

[0019] The cutting processing unit 40 cuts and separates the compressed waste hc in the compression processing chamber 12 in the vertical and horizontal directions by working in cooperation with the pressing plate 30 which moves forward within the compression processing chamber 12. As the pressing plate 30 moves forward, the compressed waste hc pushed out from the opening 14 on the front of the casing 11 is cut and divided into a number of divided bodies hc1 and discharged to the outside (see Figure 6).

[0020] In the illustrated example, the cutting processing section 40 is composed of a frame 41 attached around the opening 14 of the casing 11, and a plurality of cutter members 42h, 42v (four in the illustrated example) attached in a lattice pattern to the frame 41. Two cutter members 42h are arranged horizontally to the opening 14 and parallel to each other, and the remaining two cutter members 42v are arranged vertically to the opening 14 and parallel to each other.

[0021] The cutter members 42h, 42v are made of plate-like members and are provided with an acute-angled portion, i.e., a blade portion 42a having an acute cross-section, on the side facing the pressing plate 30. The frame 41 and the cutter members 42h, 42v are all made of metal such as iron or steel.

[0022] The number and arrangement of the cutter members 42 in the cutting processing section 40 are not limited to the illustrated example. One or many cutter members may be arranged only in the horizontal direction relative to the opening 14, one or many cutter members may be arranged only in the vertical direction, or one or many cutter members may be arranged in a lattice pattern in both the horizontal and vertical directions. This may be determined appropriately depending on the type of waste to be fed and the compression capacity of the cylinder 31.

[0023] A horizontal closing plate 32 extending rearward is attached and supported on the upper surface of the pressure plate 30. This horizontal closing plate 32 closes the opening (communication port) 12 between the upper hopper 20 and the compression treatment chamber 12 when the pressure plate 30 moves forward, and completely closes the opening 12 when the pressure plate 30 moves forward to the maximum extent, thereby preventing waste fed into the hopper 20 from falling into the rear chamber of the casing 11.

[0024] Typical examples of waste materials fed into the hopper 20 include, but are not limited to, waste plastics made of soft or hard plastics, and paper such as cardboard. Soft plastics include vinyl sheets, packaging films, agricultural films, and flexible containers. Hard plastics include PET bottles, pallets, vinyl pipes, and plastic parts used in the bodies of home appliances and automotive parts. Paper includes the above-mentioned cardboard, paper cartons, newspapers, and magazines.

[0025] Next, a method for compressing and cutting the collected waste plastic using the compression and cutting device S having the above-mentioned configuration will be described below with reference to Figs. 5 and 6, including the steps up to processing into pellets as an example.

[0026] First, as shown in FIG. 5(A), collected waste plastic (waste material) h is sequentially fed into the upper hopper 20 of the compression and cutting device S, and when the compression processing chamber 12 is filled with waste plastic h as shown in FIG. 5(B), the cylinder 31 is actuated to advance the pressure plate 30 in the rear chamber toward the compression processing chamber 12 in the front chamber.

[0027] As shown in Fig. 6(A), as the pressing plate 30 advances, the waste plastic in the compression chamber 12 is compressed to become compressed waste plastic hc (compressed waste), which is then pushed into the cutting processing section 40 through the opening 14. When the pressing plate 30 advances further, as shown in Fig. 6(B), the compressed waste plastic hc is cut by the blades 42a of the cutter members 42h, 42v arranged in a lattice pattern in the cutting processing section 40 so as to be separated in the vertical and horizontal directions, and is subdivided into a large number of divided bodies hc1 and roughly crushed.

[0028] The roughly crushed compressed waste plastic division bodies hc1 are discharged onto the belt conveyor 50 in front of the device main body 10, and are transported on the Belco conveyor 50 to the subsequent process.

[0029] Next, the pressing plate 30 is moved back to its original position by the operation of the cylinder 31, and the waste plastics h put into the upper hopper 20 fall into the compression chamber 12 as shown in Fig. 5(A). When the compression chamber 12 is filled with the waste plastics h, the pressing plate 30 is again moved forward toward the compression chamber 12 as shown in Fig. 6(A), compressing the waste plastics h in the compression chamber 12 and pushing the compressed waste plastics hc into the cutting processing section 40 from the opening 14, where they are cut and roughly crushed by the cutter members 42 and discharged onto the belt conveyor 50.

[0030] At this time, even if the preceding compressed waste plastic hc has a portion that has not been divided (especially the rear end portion of the compressed waste plastic hc), the following compressed waste plastic hc presses that portion against each cutter member 42h, 42c of the cutting processing section 40, so that that portion is reliably cut.

[0031] The compressed waste plastic fragments transported to the post-process are secondarily crushed and pulverized by a crusher / grinding machine, then washed, sorted, and processed into pellets.

[0032] According to the compression cutting device S of this embodiment, the waste plastic fed from the upper hopper 20 into the compression processing chamber 12 is compressed by the pressure plate 30 operated by the cylinder 31, and then cut as is by the lattice-shaped cutter members 42h, 42v of the front compression processing section 40, so that roughly crushed waste plastic divided bodies can be efficiently obtained from the compressed waste plastic.

[0033] In addition, according to the compression cutting device S of this embodiment, the collected waste plastic can be compressed and cut, and then roughly crushed efficiently, so that the subsequent processing steps for recycling can be carried out efficiently, and recycled pellets, etc. can be produced efficiently and at low cost.

[0034] Waste that can be roughly crushed by the compression and cutting device S of this embodiment is not limited to waste plastic. Paper such as cardboard and paper cartons can also be efficiently roughly crushed by compressing and cutting, and the subsequent post-process for recycling such as secondary crushing and melting can be efficiently advanced. Materials that can be compressed and cut include wood, for example, waste wood generated by demolishing houses, and metals that can be cut by the cutter unit 40, for example, waste metals such as aluminum materials, which can be efficiently roughly crushed.

[0035] As explained above, the compression and cutting device of the present invention can efficiently compress and cut waste plastics, paper, wood, metals, and other household and industrial waste discharged from homes and factories, and roughly crush them, allowing the downstream recycling process to be carried out efficiently.The present invention can greatly contribute to the effective use of resources and the realization of a circular society.
