BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing device for an NC router which presses a warped scrapboard or a wood processing plate placed on a suction table against the suction table.

[0002]

2. Description of the Related Art When a wood processing board is processed by an NC router, first, a scrap board is placed on a suction table and positioned, and then the wood processing board is positioned on the scrap board.

[0003]

Generally, although the scrap and the wood working plate which have no warp can be easily positioned on the suction table, the scrap and the wood working plate are usually flat. Since there is no warp and there is almost no warp, the scrapboard is not immediately absorbed even when it is placed on the suction table, and if it is not absorbed, it is adsorbed by holding it down manually, and similarly, the wood processing board Also, in the case of not being adsorbed when placed on the throwing plate, there is a problem that it cannot be made unmanned because it is adsorbed by holding it down manually.

Further, in the case of a wood working plate having a very large warp, if it is not adsorbed on the adsorption table even by hand, the wood working plate should be removed and the next wood working plate should be placed. Although it must be done, there is a problem that it can not be made unmanned because there is manpower in the work.

SUMMARY OF THE INVENTION The present invention is a spindle motor in which a head structure is mounted on a slide base which is moved by a rail of a support, and a tool such as a drill or a cutter is mounted on a rotary shaft of the head structure. Mounting a head provided with, moving the head structure and the suction table on the rail,
In an NC router adapted to process a wood working plate positioned on a suction table or a scrap plate, a plurality of pressing cylinders mounted on the slide base, and a plurality of pressing members that move up and down by driving the pressing cylinders. Is provided.

[0006]

In the present invention, when a warped waste plate or a wood working plate is placed on the suction table, the suction table and the slide base move to hold the warped portion of the waste plate or the wood processed plate as a pressing member. Move below.

Then, the pressing member is lowered by the pressing cylinder, and the scraping plate or the wood working plate is sucked onto the suction table by pressing the scraping plate or the wood processing plate with the pressing member.

1 is a front view of an NC router according to an embodiment of the present invention, FIG. 2 is a front view of an NC router provided with a holding device according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. 4 is a side view of an NC router provided with a holding device of FIG. 4, and FIG. 4 is a plan view of an NC router provided with a holding device of one embodiment of the present invention, in which a rail 2 is mounted on a support 1 and a head structure is mounted on the rail 2. The slide base 3 is supported by the slide base 10 so as to move left and right in the drawing.

A head 4 is mounted on the head structure 3, a motor is mounted on each of the heads 4, and a tool such as a drill or a cutter is mounted on the rotary shaft of the motor. .

Further, a tool changing device 5 is provided on the side of the head 4.
Also, a tool magazine 6 is mounted, and a large number of tools 7 are mounted in this tool magazine 6.

Further, a rail 8 is mounted on the support base 1 below the head 4, and a suction table 9 is mounted on the rail 8 so as to move to the front and rear of the head 4.

Ruler stoppers 11 and 12 are attached to the support base 1 at two corners of the suction table 9 and separated from the suction table 9, and are placed on the suction table 9 by the ruler stoppers 11 and 12. The discard board 13 and the wood processing board 14 are positioned.

A duct 15 is attached to the upper portion of the head 4, a valve (not shown) that is opened and closed by a cylinder 16 is provided in the duct 15, and a hose (not shown) is connected to the duct 15. The lower end of this hose is provided in the vicinity of the lower part of the head 4, and is configured to suck chips and dust on the table 9.

Further, two supporting arms 17 are protruded toward the suction table 9 on the slide base 10 so as to sandwich the head 4, the tool changing device 5 and the tool magazine 6, and
Both ends of the support member 18 are fixed to the support arm 17 so as to surround the head 4, the tool changing device 5, and the tool magazine 6, and a plurality of cylinders 19 and guides 20 are attached to the support member 18, and the operation of the cylinder 19 is performed. A pressing member 21 is fixed to the shaft and the lower end of the guide 20.

In the pressing device of this embodiment having the above-described structure, first, as shown in FIG. 3, the scraping plate 13 having suction holes corresponding to the size of the wood working plate 14 is placed on the suction table 9. When it is placed, it is pressed against the ruler stoppers 11 and 12 to be positioned and adsorbed on the adsorption table 9.

At this time, when the scrap plate 13 is warped and is not sucked to the suction table 9, the suction table 9 and the slide base 10 move to move the scrap plate 13 below the pressing member 21 and operate the cylinder 19. Then, the pressing member 21 is lowered, and the scrap plate 13 is sequentially pressed to be sucked onto the suction table 9.

After the scrap plate 13 is placed on the suction table 9 in this manner, the wood processing plate 14 is placed on the scrap plate 13 and pressed against the ruler stoppers 11 and 12 to be positioned. When the wood working plate 14 warps and is not adsorbed on the scrap plate 13 on the adsorption table 9, the adsorption table 9 and the slide base 10 are similarly moved to move the wood processing plate 1
4 is moved to the lower side of the pressing member 21, and the cylinder 19 lowers the pressing member 21 to sequentially press the wood working plate 14, so that the wood working plate 14 is placed and adsorbed on the scrap plate 13.

In the present embodiment, when the scrapboard 13 and the wood processing board 14 are warped in this manner, the cylinder 19 is operated to lower the presser 21 to press the scrapboard 13 and the wood processing board 14. Therefore, the discarding board 13 and the wood processing board 14
Even if there is a warp, it can be adsorbed on the adsorption table 9, thus improving the work efficiency.

The pressing member 21 provided at the lower ends of the cylinder 19 and the guide 20 may be a plate-shaped member, or a pressing roller may be attached.

When this pressing roller is used, when the scrapboard 13 placed on the suction table 9 or the wood processing board 14 placed on the scrapboard 13 is warped, the suction table 9
When the cylinder 19 is actuated and the pressing roller is moved down while moving, the scraping plate 13 or the wood working plate 14 is moved while contacting the pressing roller, so that the scraping plate 13 and the wood working plate 14 can be pressed smoothly. It can be carried out.

Further, in the description of the above embodiment, the wood processing board 1
Although an example in which one head 4 for processing 4 is provided has been described, an NC router provided with a plurality of heads may be used, or a wood processing board 14 may be placed on the scrap board 13 to further process the wood processing board 14.
Although the example of processing the wood is shown, the wood processing plate 14 may be placed directly on the suction table 9.

[0022]

As described above, the press device for the NC router of the present invention is capable of adsorbing to the adsorption table while eliminating the warp in the scrapboard or the wood processing plate, when the warp is present. There is an advantage that the work efficiency can be improved.
