Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is directed to an NC router which presses a warped discarded or processed wood plate placed on a suction table against a suction table and removes chips on the suction table. The present invention relates to a dust collector.

[0002]

2. Description of the Related Art When processing a wood-processed board with an NC router, first, a discarded board is placed on a suction table and positioned, and then the wood-processed board is positioned on the discarded board. At this time, chips are scattered on the suction table or the discarded plate, so that the chips are collected by a dust collector provided in the head.

[0003]

[0005] In the processing of wood, although there is no warpage in the discarded and wood-processed boards, positioning on the suction table can be easily performed. Since there is no flat thing and it is almost warped, the discarded plate is not immediately sucked even if it is placed on the suction table, and if it is not sucked, it is sucked by pressing it by hand, However, even if a wood-processed board is not adsorbed when it is placed on a discarded plate, it takes time to position the discarded board and the wood-processed board because it is adsorbed by being pressed by hand. Was.

[0004] In addition, in the case of a woodworking board having a very large warp, if the woodworking board is not adsorbed on a suction table even by manual operation, the woodworking board must be removed and the next woodworking board must be placed. However, there is a disadvantage that the operation takes a very long time.

[0005] Further, since chips generated when processing wood are not scattered only near the head, but are scattered widely on the table, they may be scattered on the table. When positioning on a board,
Chips may be clogged in the suction holes of the table or trash plate, making it impossible to position the wood-processed plate. Also, chips may create a gap between the table and the trash plate or between the trash plate and the wood-processed plate. There is a disadvantage that the plate cannot be positioned in some cases.

[0006]

According to the present invention, one or a plurality of heads provided with a spindle motor having a tool such as a drill or a cutter mounted on a rotary shaft are mounted on a head structure moved by rails of a support base. Then, in the NC router in which the head structure and the suction table are moved on orthogonal rails to process a wood-processed plate positioned on the suction table or the discarded plate, the front surface of the head structure is provided.

[0007]

According to the present invention, when a warped discarded or wood-processed board is placed on a suction table, the suction table moves and a warped portion of the discarded or wood-processed board is held down by a presser plate or presser. Move below the rollers.

Then, the holding plate or the holding roller is lowered by the holding cylinder, and the holding plate or the holding plate is pressed by the holding plate or the holding roller so that the waste plate or the working plate is attracted to the suction table. You.

Next, when the processing is completed, the wood processing board is removed from the table, and then the table is moved, and at the same time, the apparatus is operated to remove the scrap and the chips on the table by the dust collecting apparatus. After collecting the dust, the next work board is positioned on the table.
