Summary of the Invention

Problems to be Solved by the Invention

[0004] Under such circumstances, there is a strong demand for a novel mechanism that can cut objects to be processed more efficiently at present.

[0005] Therefore, an object of the present invention is to provide a cutting machine capable of efficiently cutting an object to be processed.

Means for Solving the Problems

[0006] The present invention is a cutting machine for cutting an object to be processed including garbage, comprising a device main body having an accommodation space inside, and disposed on the device main body, through an inlet portion communicating with the accommodation space, the object to be processed can be input into the accommodation space, and on one side portion of the device main body, an outlet portion through which the object to be processed input into the accommodation space is discharged is formed, and the accommodation capacity space is such that the object to be processed can be input into it, and on one side portion of the device main body, an outlet portion through which the object to be processed input into the accommodation space is discharged is formed, and the accommodation capacityA movable pressing portion is provided at a position opposite the outlet portion of the space, and in the main body of the device, the receiving portion of the outlet portion capacity The cutting machine is characterized in that multiple rods are arranged in a grid pattern on the space side, through holes are formed between the rods through which the material to be processed in the storage space passes when it is pushed toward the discharge port as the pressing part moves, guide parts are provided at the intersections of the rods that are extended toward the storage space, the outer diameter of the guide parts increases from the tip to the base and the side surface serves as a guide surface, and a shredding blade is formed in the portion of the rod between adjacent guide parts, with the cutting edge facing toward the storage space, and the material to be processed pushed by the pressing part is guided toward the shredding blade by the guide surface.

[0007] In this configuration, the material to be processed, placed in the storage space, is cut to an appropriate size by the shredding blades. Furthermore, the guiding action of the guide surface formed on the side surface of the guide section guides the material to be processed to the shredding blades surrounding the guide section, significantly improving the efficiency of the cutting work. Although the sharpness of the shredding blades may vary from part to part depending on the degree of polishing during maintenance, in this invention, the guiding action of the guide section allows the material to be sequentially pushed and guided to the parts with good sharpness. Incidentally, if the shredding section consists of multiple blade members arranged in a row, and each blade member is polished individually, over many years of polishing, the shape, dimensions, and orientation of the cutting edge of each blade member will gradually differ due to the polishing process. This can lead to discontinuities such as steps forming at the boundaries between the blade members, resulting in uneven cutting of the workpiece or problems such as the workpiece getting stuck. However, the present invention has the advantage of appropriately resolving such problems because a guide section is provided at the intersection of the rod members, pushing the workpiece along the surrounding shredding section. [Effects of the Invention]

[0008] The cutting machine of the present invention has the excellent effect of being able to efficiently cut the material to be processed. [Brief explanation of the drawing]

[Figure 6] This is an explanatory diagram illustrating the third state of the cutting machine. [Modes for carrying out the invention]

[0010] The following describes in detail examples of the present invention. However, the present invention is not limited to the examples shown below, and design modifications can be made as appropriate.

[0011] As shown in Figure 1, the cutting machine 1 comprises a box-shaped device body 10 having an internal storage space S.

[0012] The top of the main body 10 of the device is provided with an input port 11 that communicates with the storage space S, allowing the materials to be processed D, such as garbage sealed in garbage bags, to be inserted into the storage space S from the outside via the input port 11.

[0013] Furthermore, one side of the main body 10 of the device, that is, one side (the left end in Figure 1), is provided with an outlet 15 through which the material to be processed D, which has been placed into the storage space S, is discharged.

[0014] In contrast, within the housing space S of the device body 10, a wall-shaped pressing portion 20 is provided that can reciprocate from the other side (right end in Figure 1) toward the discharge port 15. The pressing portion 20 is made movable laterally toward the discharge port 15 by a hydraulic cylinder 21.

[0015] Also, above the discharge port 15 of the apparatus main body 10, a guillotine blade portion 30 for cutting the workpiece D discharged from the discharge port 15 is disposed. The guillotine blade portion 30 is composed of a plate-shaped member having a blade portion formed at the lower end portion, and is configured to cut the workpiece D when descending toward the position of the discharge port 15.

[0016] Also, as shown in FIGS. 2 and 3, a plurality of crossbars 41 are arranged vertically and horizontally in the discharge port 15 to form a lattice shape, and a plurality of through holes 42 are formed between the crossbars 41. Further, on the side edge portion of the crossbar 41 on the side of the accommodation space S, a shredding blade portion 51 with a blade tip directed toward the accommodation space S is formed along the longitudinal direction of the crossbar 41. Furthermore, at each intersection portion of the crossbars 41, a conical guiding portion 55 is formed toward the accommodation space S. As shown in FIG. 3(b), the member constituting the guiding portion 55 includes a conical pointed main body portion 56, and a screw-shaped mounting portion 57 is disposed at the base end portion of the pointed main body portion 56. Then, by screwing the mounting portion 57 to the crossbar 41, the guiding portion 55 is arranged at the intersection portion.

[0017] Next, the cutting process by the cutting machine 1 will be described.

[0018] 〔First state〕 In the cutting machine 1, as shown in FIG. 4, first, the workpiece D (in a state where garbage or the like is enclosed in a garbage bag or in a state of garbage or the like) is introduced from the inlet 11 into the accommodation space S.

[0019] 〔Second state〕 Next, as shown in FIG. 5, the pressing portion 20 is operated to push the workpiece D toward the discharge port 15 side. Then, the workpiece D is finely cut by the shredding blade portion 51 and the guiding portion 55 of the crossbar 41 disposed at the discharge port 15 and continuously discharged to the outside through the through hole 42. Since the guiding portion 55 is conical and the shredding blade portion 51 is disposed around the guiding portion 55, the outer peripheral surface of the guiding portion 55 functions as a guiding surface for guiding the workpiece D toward the shredding blade portion 51 side.

[0020] [Third state] After the material to be processed D is discharged from the discharge port 15, the guillotine blade 30 is lowered to further cut the continuously discharged material to be processed D, as shown in Figure 6.

[0021] The cutting machine 1, with its shredding blade section 51 and guide section 55, can effectively cut the material to be processed D within the storage space S, dramatically improving work efficiency. Specifically, it is possible to reduce the number of workers and working time to about one-tenth of the original amount. Furthermore, it is very quiet, making it easier to select an installation location compared to conventional machines.

[0022] The embodiments described above can be modified as appropriate. For example, the shape of the guide section 55 is not limited to a conical shape, and any shape that can suitably cut the workpiece D or suitably guide the workpiece D toward the shredding blade section 51 can be preferably selected.
