Abstract

(57) [Abstract] [Purpose] To provide a holding device for an NC router that facilitates positioning of a warped waste wood plate or a wood processing plate on a suction table. [Structure] A lower end of a U-shaped support frame 17 is fixed to a support base 1, a cylinder 20 and a guide 21 are attached to the support frame 17, and a presser foot 22 is attached to the cylinder 20 and the guide 21. When the scrap plate 13 having a warp is placed on the suction table 9, the scrap plate 13 is difficult to be sucked on the suction table 9, so the suction table 9 moves to the position below the pressing device. By pressing the top of 13 with the presser 22, the scrap plate 13 can be easily positioned on the suction table 9. Further, when the wood processing board 14 is placed on the waste board 13, if the wood processing board 14 is warped, the wood processing board 14 is also unlikely to be adsorbed on the waste board 13, and therefore the adsorption table 9 is used. The wood working plate 14 is easily moved by pressing the wood working plate 14 by pressing the wood working plate 14 under the pressing device.
Can be positioned on top.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressing device for an NC router that presses a warped scrapboard or a wood processing plate placed on a suction table against a suction table.

[0002]

[Prior art]

 When processing a wood processing board with an NC router, first, a scrap board is placed and positioned on a suction table, and then the wood processing board is positioned on this scrap board.

[0003]

[Problems to be solved by the device]

 Generally, if there is no warp in the scrapboard and the processed wood plate, the positioning on the suction table can be easily performed, but since the scrapboard and the processed wood plate are usually not flat, there is almost no warp. When the scrapboard is placed on the suction table, it is not immediately adsorbed.If it is not adsorbed, it is adsorbed by holding it down manually. If it is not adsorbed when placed, it is adsorbed by holding it down manually, so there is a problem that it takes time to position the scrapboard and the wood processing board.

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. It had to be done, but it had the drawback of being very time consuming.

[0005]

[Means for Solving the Problems]

 According to the present invention, one or a plurality of heads provided with a spindle motor in which a tool such as a drill or a cutter is attached to a rotary shaft is mounted on a head structure that is moved by a rail of a support, and the head structure and suction head In an NC router in which a table is moved on a rail to process a wood working plate positioned on a suction table or a scrapboard, the NC router is fixed to the above-mentioned support base and is attached to the support frame. And a plurality of pressing plates or rollers that are moved up and down by the driving of the pressing cylinders.

[0006]

[Action]

 In the present invention, when a warped waste plate or a wood working plate is placed on the suction table, the suction table moves and the warped portion of the waste plate or the wood processed plate is pressed by the pressing plate or the pressing roller. Move down.

Then, the press plate or the press roller is lowered by the press cylinder, and the press plate or the press roller presses the scrap plate or the wood processing plate onto the scrap plate or the wood processing plate to adsorb onto the suction table. To be done.

【Example】

 1, 2 and 3 are a front view, a plan view and a side view of an NC router according to an embodiment of the present invention, in which a rail 2 is mounted on a support 1 and a head structure 3 is mounted on the rail 2. It is supported to move left and right.

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. .

A tool changing device 5 and a tool magazine 6 are mounted on the side of the head 4, a large number of tools 7 are mounted on the tool magazine 6, and safety fences 10 are mounted on both sides of the head 4. .

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 in front of and behind the head 4.

Further, 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 scrapboard 13 and the wood processing board 14 are positioned.

A duct 15 is attached to the upper part 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 portion of the head 4 and is configured to suck chips and dust on the table 9.

In addition, as shown in FIGS. 2, 3 and 4, the lower end of the U-shaped support frame 17 is fixed to the support base 1 in front of the head 4, and the support frame 17 is provided as shown in FIG. The support portions 18, 19 are fixed to the support portions 18, 19, and a plurality of cylinders 20 and guides 21 are fixed to the support portions 18, 19, respectively, and a presser 22 is attached to the lower ends of the cylinders 20 and guides 21.

In the presser dust collecting apparatus of the present embodiment configured as described above, first, as shown in FIG. 1, the scraping plate 13 having suction holes corresponding to the size of the wood working plate 14 of the suction table 9 is provided. When it is placed on the upper side, 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 warps and is not sucked by the suction table 9, the suction table 9 moves, the cylinder 20 operates and the presser foot 22 is lowered, and the scrap plate 13 is sequentially pushed and sucked. Adsorb to the table 9.

After the waste plate 13 is placed on the suction table 9 in this manner, the wood processing plate 14 is placed on the waste 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, similarly, the adsorption table 9 is moved, and the presser 22 is lowered by the cylinder 20 to sequentially press the wood processing plates 14 in sequence. The wood processing board is placed on the scrap board and adsorbed.

In the present embodiment, when the scrap plate 13 and the wood processing plate 14 are warped in this way, the cylinder 20 is operated to move the presser foot 22 downward to press the scrap plate 13 and the wood processing plate 14. Even if there is a warp, it can be adsorbed on the adsorption table 9, so that the work efficiency is improved.

Although the presser foot 22 is attached to the lower ends of the cylinder 20 and the guide 21 in the above description of the embodiment, a presser roller may be attached instead of the presser foot 22.

When this pressing roller is used, the suction table 9 is moved when the scrapboard 13 placed on the suction table 9 or the wood processing board 14 placed on the scrapboard 13 is warped. Meanwhile, when the cylinder 20 is operated and the presser roller is lowered, the scrap plate 13 or the wood processing plate 14 is moved in contact with the press roller, so that the scrap plate 13 and the wood processing plate 14 can be pressed smoothly. It can be carried out.

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

[0022]

[Effect of device]

 As described above, the NC router pressing device of the present invention can eliminate the warp of the scrapboard and the wood processing plate when they are warped, and can adsorb them on the suction table, thus improving the work efficiency. There is an advantage that it can be improved.
