[0046] <Sliding door structure>

[0047] The sliding door structure 200 is located behind the rotating blade 61B and the useless object storage part 11 in the Y direction. The sliding door structure 200 includes: a sliding door 20 configured to be able to reciprocate linearly in the X direction; a centrally convex guide rail 23 located in front of the sliding door 20 in the Y direction and configured to enable the sliding door 20 to reciprocate linearly in the X direction; a centrally concave roller 25 located in front of the sliding door 20 in the Y direction; a connecting member 24 connecting the sliding door 20 and the roller 25; a bottom member 26 having a bottom surface extending in the X direction below the sliding door 20 in the Z direction; and a guide rail cover 21 configured to cover the guide rail 23. The guide rail cover 21 includes: an upper surface 21a covering the upper part of the guide rail 23 in the Z direction; and a side surface 21b covering the front part of the guide rail 23 in the Y direction.

[0050] Figure 4A schematic perspective view of the sliding door structure 200 viewed from the inside of the cutting device 100 according to the embodiment is shown. Figure 5 Show Figure 4 The partial perspective view of the sliding door structure 200 is shown in FIG. Figure 4 and Figure 5 As shown, the sliding door structure 200 includes: a waste removing member 28 configured to remove waste on the guide rail cover 21; and a holding member 27 configured to hold the waste removing member 28 by making at least a portion of the waste removing member 28 contact the upper surface 21a of the guide rail cover 21. In this embodiment, the holding member 27 is a guide cover receiving member configured to receive the guide rail cover 21, and the waste removing member 28 is configured to block at least a portion of the gap between the guide rail cover 21 and the guide cover receiving portion as an example of the holding member 27. At the end of the sliding door structure 200, the holding member 27 is provided above the upper surface 21a of the received guide rail cover 21 with a gap from the guide rail cover 21. Thus, the holding member 27 is configured to receive the guide rail cover 21 mounted on the sliding door 20 when the sliding door 20 is moved in the X direction to open the sliding door 20. In addition, one end of the waste removing member 28 in the Z direction, that is, the upper end, is fixed to the holding member 27, and the other end of the waste removing member 28 in the Z direction, that is, the lower end, is open. Figure 5 As shown, a portion of the guide rail 23 is received in the retaining member 27 .

[0051] <Mechanism of action of the cutting device>

[0052] Figure 6 A schematic plan view showing an example of a cutting object W cut by the cutting mechanism of the cutting device 100 according to the embodiment. Figure 6 The cut object W shown is Figure 3 The rotary blade 61B as the cutting mechanism shown in the figure is cut to produce a plurality of products P and their scraps S. Here, the scraps S are cut by themselves. Figure 3 The liquid ejected from the second nozzle 32 as the scattering mechanism is scattered to the rear of the rotating blade 61B in the Y direction. Figure 2 The second protective cover 10B shown is indirectly housed in the useless-object storage portion 11 , or is directly housed in the useless-object storage portion 11 .

[0053] However, a part of the scraps S scattered to the rear of the rotary blade 61B in the Y direction may not be accommodated in the waste storage portion 11 but may accumulate on the Figure 2On the guide rail cover 21 of the sliding door structure 200 shown. When the sliding door 20 is opened in a state where the scraps S are accumulated on the guide rail cover 21, the scraps S accumulated on the guide rail cover 21 are also accommodated in the retaining member 27 together with the guide rail cover 21. If useless materials, i.e., scraps S, are accumulated on the retaining member 27, the movement of the sliding door 20 will be hindered. In addition, sometimes at least a part of the scraps S accumulated inside the retaining member 27 collapses and falls onto the guide rail 23 inside the retaining member 27. In this case, when the sliding door 20 is temporarily closed and opened again afterwards, the movement of the sliding door 20 may be hindered by the scraps S on the guide rail 23 inside the retaining member 27.

[0054] The cutting device 100 of the embodiment includes a waste material removing member 28, and the waste material removing member 28 is held by the holding member 27 in a manner that at least a portion of the waste material removing member 28 contacts the upper surface 21a of the guide rail cover 21. Therefore, even when the sliding door 20 is opened in a state where the scraps S are accumulated on the guide rail cover 21, the waste material removing member 28 can suppress the scraps S accumulated on the guide rail cover 21 from entering the inside of the holding member 27. Therefore, in the cutting device 100 of the embodiment, compared with the previous cutting device, it is possible to suppress the situation in which the movement of the sliding door is hindered by the accumulation of scraps scattered when the cutting object is cut.

[0055] Figure 7 A schematic plan view showing a preferred example of the waste removal member 28. Figure 7 As shown in FIG. 1 , the waste removing member 28 is configured to extend in a direction inclined in a manner extending from the rear to the front in the Y direction. In this case, when the sliding door 20 is opened and the guide rail cover 21 is accommodated in the holding member 27, the scraps S accumulated on the guide rail cover 21 can be moved to the left side of the guide rail cover 21 by the waste removing member 28. Figure 7 The waste material is moved in the direction of the arrow shown and stored in the waste storage portion 11.

[0056] Figure 8 A schematic side view showing a preferred example of the waste removal member 28 and the guide rail cover 21. Figure 8 As shown, the upper surface of the guide rail cover 21 and / or the waste removing member 28 is configured to extend in a manner that is inclined downward in the Z direction relative to the Y direction toward the waste storage portion 11 (that is, inclined from the sliding door 20 side toward the inner lower part of the cutting device 100). In this case, when the guide rail cover 21 is accommodated in the holding member 27, the scraps S accumulated on the guide rail cover 21 can also be moved to the left by the waste removing member 28. Figure 7 The waste material is moved in the direction of the arrow shown and stored in the waste storage portion 11.

[0057] The material of the waste removal member 28 is not particularly limited as long as it is a material that can block the scraps S located on the guide rail cover 21 when the sliding door 20 is opened, and prevent the scraps S from entering the opposite side separated by the waste removal member 28 (in the present embodiment, since the retaining member 27 is a guide rail cover receiving member, it is the side of the sliding door 20 that moves when the sliding door 20 is opened in the space separated by the waste removal member 28). Fig. 9 A schematic partial side view of a preferred example of the waste removal member 28 is shown. Fig. 9 As shown, it is preferred that the waste removing member 28 is arranged in contact with the upper surface 21a of the guide rail cover 21, and is configured so that the lower end of the waste removing member 28 in the downward direction of the Z direction is oriented in the X direction so as to face the scraps S accumulated on the guide rail cover 21 through the guide rail cover 21. In this case, since the lower end of the waste removing member 28 can be prevented from being oriented toward the holding member 27 by the guide rail cover 21, it is possible to further suppress the scraps S accumulated on the guide rail cover 21 from entering the interior of the holding member 27. In order to set such a structure, it is preferred that the waste removing member 28 includes a flexible material or an elastomeric material, and as such a material, rubber or a brush can be cited, and a brush is particularly preferred.

[0058] <Second embodiment>

[0059] In the second embodiment, a case where the holding member 27 is not configured as a rail cover accommodating member capable of accommodating the rail cover 21 will be described. Fig.10 Shows a single side in the X direction ( Fig.10 A schematic perspective view of a sliding door structure of a cutting device of a reference example not having a guide rail cover housing member. Fig.10 In the cutting device of the reference example shown in the figure, due to the reasons described above, scraps S, which are an example of useless materials, may sometimes accumulate on the guide rail cover 21. Fig.10 In the case of the sliding door 20 shown, for example Fig.11 As shown in the schematic stereogram of , sometimes the scraps S accumulated on the guide rail cover 21 will fall onto the guide rail 23 on the travel direction side of the sliding door 20. In this case, sometimes the movement of the sliding door 20 is hindered by the scraps S on the guide rail 23 on the travel direction side of the guide rail cover 21.

[0060] So, for example Fig.12 As shown in the schematic perspective view of the second embodiment, the cutting device of the second embodiment includes a holding member 27 such as a bracket for fixing, which is not configured to accommodate the guide rail cover 21 but can hold the useless material removing member 28. In the cutting device of the second embodiment, even if the scrap S, which is an example of useless material, is accumulated on the guide rail cover 21, for example, Fig.13 As shown in the schematic stereoscopic diagram of , the scraps S accumulated on the guide rail cover 21 can also be blocked by the waste removal member 28 that is fixed by the holding member 27 and held, and the scraps S can be accommodated in the waste storage portion 11. In addition, the holding member 27 of the second embodiment has a surface extending rearward in the Y direction in order to fix the waste removal member 28 above the holding member 27, and a gap of a degree that allows the guide rail cover 21 to pass is provided below the surface extending rearward in the Y direction. In addition, in the second embodiment, the holding member 27 has a surface extending in the X direction, a part of the side of which is joined to the front side in the Y direction of the surface extending rearward in the Y direction, and the lower end of the surface extending in the X direction is fixed to a part of the sliding door structure 200.

[0061] In addition, in the cutting device of the second embodiment, from the viewpoint of preventing useless materials such as scraps accumulated on the guide rail cover 21 from falling onto the guide rail 23 located in the travel direction of the sliding door 20 (the direction in which the sliding door opens) when the sliding door 20 is opened, the retaining member 27 is preferably arranged above the guide rail cover 21 and near the side of the position (sliding start position) where the sliding door 20 starts to slide when the sliding door 20 is opened.

[0062] In addition, in the cutting device of the second embodiment, it is also preferred that a part or all of the lower end of the waste removing member 28 is arranged to contact the upper surface 21a of the guide rail cover 21. In this case, when the sliding door 20 is opened, waste materials such as scraps S accumulated on the guide rail cover 21 can be prevented from passing through the waste removing member 28 in the direction of travel of the sliding door 20.
