<Mechanism of action of cutting device>
FIG. 6 shows a schematic plan view of an example of an object W to be cut by the cutting mechanism of the cutting device 100 of the embodiment. For example, the cutting object W shown in FIG. 6 is cut by a rotary blade 61B as a cutting mechanism shown in FIG. 3, and a plurality of products P and their scraps S are produced. Here, the scraps S are scattered behind the rotary blade 61B in the Y direction by the liquid ejected from the second nozzle 32 as a scattering mechanism shown in FIG. At this time, the scraps S are stored in the waste storage section 11 indirectly via the second protective cover 10B shown in FIG. 2, or directly stored in the waste storage section 11.

However, some of the scraps S scattered behind the rotary blade 61B in the Y direction may not be stored in the waste storage section 11 and may be deposited on the rail cover 21 of the sliding door structure 200 shown in FIG. . When the sliding door 20 is opened with scraps S accumulated on the rail cover 21, the scraps S accumulated on the rail cover 21 are also accommodated in the holding member 27 together with the rail cover 21. If the scraps S, which are unnecessary materials, accumulate on the holding member 27, the movement of the sliding door 20 will be obstructed. Further, at least a portion of the scraps S accumulated inside the holding member 27 may collapse and fall onto the rail 23 inside the holding member 27. In this case, when the sliding door 20 is closed once and then attempted to be opened again, the movement of the sliding door 20 may be obstructed by the scrap material S located on the rail 23 inside the holding member 27. Ta.

The cutting device 100 of the embodiment includes a waste removal member 28 held by a holding member 27 so that at least a portion thereof contacts the upper surface 21a of the rail cover 21. Therefore, even if the slide door 20 is opened with the scraps S accumulated on the rail cover 21, the scraps S accumulated on the rail cover 21 will enter the inside of the holding member 27 by the waste removal member 28. It is possible to prevent this from happening. Therefore, in the cutting device 100 of the embodiment, compared to conventional cutting devices, it is possible to suppress the movement of the sliding door from being hindered by the accumulation of scraps scattered during cutting of the object to be cut.

FIG. 7 shows a schematic plan view of a preferred example of the waste removal member 28. As shown in FIG. 7, the waste removal member 28 is configured to extend in an inclined direction from the rear to the front in the Y direction. In this case, when the slide door 20 is opened and the rail cover 21 is housed in the holding member 27, the scraps S accumulated on the rail cover 21 are removed by the waste removal member 28 as shown in the arrows shown in FIG. It becomes possible to move it in the direction and store it in the waste storage section 11.

FIG. 8 shows a schematic side view of a preferred example of the waste removal member 28 and the rail cover 21. As shown in FIG. 8, the upper surface of the rail cover 21 and/or the waste removal member 28 are inclined downward in the Z direction with respect to the Y direction toward the waste storage section 11 (that is, from the slide door 20 side The cutting device 100 is configured to extend downwardly inside the cutting device 100 so as to be inclined downward. Also in this case, when the rail cover 21 is housed in the holding member 27, the scraps S accumulated on the rail cover 21 are moved by the unnecessary material removal member 28 in the direction of the arrow shown in FIG. It becomes possible to accommodate the object in the object storage section 11.

The material of the waste removal member 28 is such that it dams the scraps S on the rail cover 21 when the slide door 20 is opened, and the material on the opposite side separated by the waste removal member 28 (in this embodiment, the holding member 27 Since it is a rail cover storage member, it is possible to prevent the scraps S from entering into the space partitioned by the waste removal member 28 (the side on which the sliding door 20 moves when the sliding door 20 is opened). There is no particular limitation as long as it is made of a material. FIG. 9 shows a schematic partial side view of a preferred example of the waste removal member 28. As shown in FIG. 9, the waste removal member 28 is arranged so as to be in contact with the upper surface 21a of the rail cover 21, and the rail cover 21 allows the lower end of the waste removal member 28 in the Z direction to be placed above the rail cover 21. It is preferable to be configured to face the scraps S accumulated in the X direction. In this case, since the lower end of the waste removal member 28 can be made difficult to face the holding member 27 by the rail cover 21, the scraps S accumulated on the rail cover 21 can be prevented from entering the inside of the holding member 27. can be further suppressed. In order to have such a structure, it is preferable that the waste removal member 28 is made of a flexible material or an elastic material, and examples of such materials include rubber and a brush, and a brush is particularly preferable. preferable.
