The processing apparatus illustrated here is for cutting an object to be processed such as a frame material to an arbitrary size by rotating a circular saw 1, and has a storage box 10. The circular saw 1 is the same as the one that has been widely used in the past. For example, the circular saw 1 has a circular thin plate shape having a large number of teeth on the outer peripheral surface.

The storage box 10 is for accommodating the circular saw 1 and accommodating the work chips generated during the cutting process. In the first embodiment, the upper wall portion 11 and the bottom wall portion 12 extending in the horizontal direction are provided, and the front wall portion 13 and the rear wall portion (peripheral wall) are provided between the upper wall portion 11 and the bottom wall portion 12. A hollow box-shaped storage box 10 having a portion) 14 and left and right side wall portions (adjacent vertical wall portions) 15 is illustrated. A front corner wall portion 16 is provided between the front wall portion 13 and the left and right side wall portions 15, respectively. The upper wall portion 11, the bottom wall portion 12, the front wall portion 13, the rear wall portion 14, the left and right side wall portions 15, and the left and right front corner wall portions 16 each have a flat plate shape, and are octahedral storage boxes. It constitutes 10. The circular saw 1 described above is arranged so that the axial center is substantially horizontal along the left and right sides, and can be rotated around the axial center by driving a drive source (not shown). Although not clearly shown in the figure, an elevating device is provided between the storage box 10 and the circular saw 1, and the circular saw 1 can be moved up and down with the axis aligned in the horizontal direction. is there.

In the first embodiment, the front wall portion 13, the rear wall portion 14, the side wall portion 15, and the front corner wall portion 16 of the storage box 10 are each composed of members forming a thin flat plate. On the other hand, in the upper wall portion 11 of the storage box 10, the upper surface portion 11a extending substantially horizontally serves as a processing table when cutting the object to be processed, and the upper wall portion 11 is made of a member having a thickness larger than that of the front wall portion 13. It is configured. A tool opening 11b is formed in a portion substantially central to the front wall portion 13. The tool opening 11b has a width larger than the plate thickness of the circular saw 1 and forms an elongated hole shape extending linearly from the front wall portion 13 to the rear wall portion 14. When the above-mentioned lifting device (not shown) is driven and the circular saw 1 moves upward with respect to the storage box 10, a part of the peripheral edge thereof is formed on the upper wall portion 11 via the tool opening 11b. Since it protrudes from the upper surface 11a, it is possible to cut the object to be processed arranged on the upper surface 11a of the upper wall portion 11.

The bottom wall portion 12 of the storage box 10 is provided so that the upper surface (inner bottom surface) 12a is substantially horizontal. Inside corner cover members 20 are provided on both sides of the bottom wall portion 12. The inside corner cover member 20 has a flat plate shape provided so as to cover an inside corner portion between the upper surface 12a of the bottom wall portion 12 and the inner surface of the left and right side wall portions 15 facing the inside of the storage box 10. The side wall portion 15 is inclined so as to gradually decrease as it approaches each other from the portion above the bottom wall portion 12. As is clear from the figure, in the inside corner cover member 20, the front edge portion of the front wall portion 13 and the front corner wall portion 16 is in contact with the inner surface facing the inside of the storage box 10 without a gap, and the rear edge portion is formed. The rear wall portion 14 is in contact with the inner surface facing the inside of the storage box 10 without a gap.

The front wall portion 13 of the storage box 10 is provided with a front opening 13a. The front opening 13a is a rectangular opening that communicates the inside and the outside of the storage box 10 and is formed from a portion slightly below the lower surface of the upper wall portion 11 to the upper surface 12a of the bottom wall portion 12. It is done. The width of the front opening 13a is set to be slightly smaller than that of the front wall portion 13.

A front door 30 is provided in the front opening 13a. The front door 30 is a rectangular flat plate member having a height substantially the same as the front opening 13a and a width larger than that of the front opening 13a. The front door 30 is attached to the front wall portion 13 in a state where it can be rotated around the hinge 31 axis along the upper and lower sides by a hinge 31 interposed between one side edge portion and the front wall portion 13. is there. As is clear from the figure, when the front door 30 is overlapped with the front surface of the front wall portion 13, the upper edge portion and the left and right side edges of the front opening 13a are obscured, while the lower end portion of the front door 30 is at the bottom. By being located above the upper surface 12a of the wall portion 12, a series of horizontally elongated holes extending in the left-right direction between the front wall portion 13 and the front door 30 are formed (hereinafter referred to as suction openings 10A). Will be secured. A suction guide member 32 is provided on the lower edge of the front door 30. The suction guide member 32 projects from the lower edge portion of the front door 30 toward the inside of the storage box 10 in a state of facing the upper surface 12a of the bottom wall portion 12. Although not explicitly shown in the drawing, the suction guide member 32 is provided so as to be arranged over the entire width of the front opening 13a when the front door 30 is overlapped with the front surface of the front wall portion 13. Reference numeral 33 in the drawing is a handle for opening and closing the front door 30.

Further, the storage box 10 is provided with a side suction auxiliary opening 10B and a duct 10D. The side suction auxiliary opening 10B is provided in a portion of the left and right side wall portions 15 above the inside corner cover member 20, and is formed so as to communicate the inside and the outside of the storage box 10. In the first embodiment, the side wall portion 15 is provided with a rectangular notch 15a, while the side cover member 40 is provided so as to cover the notch 15a, thereby forming a side suction auxiliary opening 10B in the side wall portion 15. I am trying to do it. That is, a side cover member 40 having a slightly shorter vertical dimension than the rectangular notch 15a is arranged, and a long hole is formed between the lower edge of the side cover member 40 and the notch 15a in the front-rear direction. A side suction auxiliary opening 10B is formed in each side wall portion 15 by securing a gap. A side suction guide member 50 is provided on the inner surface of the side wall portion 15 facing the inside of the storage box 10. The side suction guide member 50 extends from a portion above the side suction auxiliary opening 10B so as to gradually decrease toward the inside of the storage box 10, and the lower edge portion is for side suction. It is arranged so as to be located below the lower edge of the auxiliary opening 10B and above the upper surface of the inside corner cover member 20.

In the processing apparatus configured as described above, the processing chips generated when the object to be processed is being cut by the circular saw 1 are stored inside the storage box 10 through the tool opening 11b. The work chips stored in the storage box 10 are guided to the center of the bottom wall portion 12 by the inside corner cover member 20, and the portion that becomes the inside corner between the side wall portion 15 and the bottom wall portion 12 and the portion that becomes the entrance corner. There is no risk of depositing on the inside corner between the rear wall portion 14 and the side wall portion 15. Further, when the dust collector is driven from this state, the processing waste contained in the storage box 10 is sucked and discharged to the dust collector through the duct 10D.

Here, according to this processing apparatus, since the suction opening 10A is provided in the front wall portion 13 facing the rear wall portion 14 in which the duct 10D is provided, the inside of the storage box 10 is provided through the suction opening 10A. The work chips contained in the upper surface 12a of the bottom wall portion 12 are efficiently guided to the duct 10D by the air sucked into the bottom wall portion 12. That is, as shown in the comparative example of FIG. 7C, in the storage box 10 that does not have the suction opening 10A, the air sucked from the tool opening 11b of the upper wall portion 11 is the bottom wall portion. Since it diffuses in all directions on the upper surface 12a of the 12 and flows toward not only the rear wall portion 14 but also the side wall portion 15 and the front wall portion 13, the processing waste stored in the storage box 10 also flows toward the side wall portion 15 and the front wall portion 13. Will spread towards. As a result, the amount of processing waste sucked and discharged from the duct 10D is also reduced, and there is a concern that a large amount of processing waste may remain in the storage box 10.

On the other hand, according to the processing apparatus provided with the suction opening 10A in the front wall portion 13, most of the processing waste contained in the storage box 10 is the suction opening 10A as shown in FIG. 7A. It is guided to the rear wall portion 14 side by the air sucked from the duct 10D, and is sucked and discharged from the duct 10D. As a result, the frequency of the work of removing the processing debris remaining in the storage box 10 is reduced, so that the handling of the processing apparatus can be facilitated. In particular, according to the above-mentioned processing apparatus, since the suction guide member 32 is provided at the upper edge of the suction opening 10A, the air sucked into the inside of the storage box 10 through the suction opening 10A is the bottom wall portion. Since the guide is provided along the upper surface 12a of the twelve, it is possible to more efficiently suck and discharge the work waste from the duct 10D.

Further, in the above-mentioned processing apparatus, the side wall portion 15 is provided with the side suction auxiliary opening 10B, and the side suction guide member 50 is provided. Therefore, when the dust collector is driven, as shown in FIG. 7B, air is sucked into the storage box 10 from the side suction auxiliary opening 10B, and the sucked air is used as the side suction guide. Since the member 50 guides the inside corner cover member 20 along the upper surface of the inside corner cover member 20, there is no concern that processing dust may be accumulated on the upper surface of the inside corner cover member 20.

As a result, according to the above-mentioned processing apparatus, the processing waste is efficiently sucked and discharged from the duct 10D, and the amount of the processing waste remaining in the storage box 10 is significantly reduced. The frequency of the above becomes even lower, and it becomes possible to facilitate the handling of the processing apparatus.

In the first embodiment described above, since the side suction auxiliary opening 10B is provided in the storage box 10 in addition to the suction opening 10A, the processing waste of the storage box 10 can be sucked and collected more efficiently. However, the present invention is not limited to this, and it is sufficient if the suction opening 10A is provided only in the front wall portion 13 facing the rear wall portion 14 in which the duct 10D is provided. Further, the suction auxiliary opening to be added to the suction opening 10A in order to improve the efficiency of suction recovery does not necessarily have to be provided in the side wall portion 15, and for example, as in the second embodiment of FIG. 7 shown below, the storage box 10 It may be provided on the upper wall portion 11.
