Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction table of an NC router that does not require a scrap plate (suction jig plate).

[0002]

2. Description of the Related Art In a conventional NC router, as shown in FIGS. 9, 10 and 11, a rail 2 is attached to a frame 1, and a head structure 3 is moved to the left and right in FIG. Supported by the head structure 3 and a plurality of heads 4
(Four in the figure) are mounted, a motor is mounted on each of these heads 4, and a processing tool 5 such as a drill or a cutter is mounted on the rotating shaft of the motor. On the table frame 6 at the bottom of the rail 7
Is mounted, and the suction table 8 is configured to move back and forth on the rail 7 in a direction orthogonal to the moving direction of the head structure 3.

In the NC router configured as described above, the suction table 8 is instructed by a command from a separately provided control device.
Set a scrapboard on the top of the woodworking material, and move the head structure 3 on the upper part of the woodworking material positioned on the wasteboard and connect it to the rotary shaft of the motor of each head 4. The processing tool 5 is configured to rotate and sequentially descend with the motor to process a wood product.

[0004]

However, in the NC router thus constructed, suction holes are formed over the entire surface of the board on the upper surface of the suction table 8, and the suction holes are connected to the blower through the duct. If the plate to be processed is placed on the board of the suction table 8 and processed, the board of the suction table 8 may also be scraped when the plate to be processed is processed. I'm using it.

By the way, this scrap plate covers the entire surface of the suction table 8, and since the scrap plate has suction holes corresponding to the shape of the plate to be processed, only the kind of the plate to be processed is scrap plate. However, there is a disadvantage in that a shelf or a place for storing such a wasteboard is required.

[0006]

According to the present invention, there is provided a head structure having one or a plurality of heads each provided with a motor having a rotary shaft on which a processing tool such as a drill or a cutter is mounted by a rail provided on a frame. Moves in the horizontal direction, and moves the suction table that sucks the plate to be processed by the table rail arranged in the direction orthogonal to the rail to the table frame arranged below the frame, in the direction orthogonal to the movement direction of the head structure. In the NC router adapted to be processed by the above-mentioned processing, a plurality of suction blocks are mounted on the suction table in parallel to the moving direction of the head structure, and hanging members are respectively mounted on the lower parts of the suction blocks, and the suction tool is passed through the processing tool. A pressing member that moves up and down by a vertical cylinder mounted on the table frame below the suction block near the position And lowering at least one suction block of the suction table to a position where it does not come into contact with the tool, and the hanging member has a bearing mounted on the lower portion thereof to operate the upper and lower cylinders mounted on the table frame. The hanging member may be lowered by a pressing member mounted on a shaft to lower the suction block, and further, air cylinders may be mounted on table bases below the plurality of suction blocks, respectively. May support the vertical movement of the suction block, or the suction block may be provided with a spring for supporting the vertical movement of the suction table on the lower table base. The member is composed of a rigid member whose lower part is bent at a right angle, and a bearing is attached to the pressing member. May be lowered drooping member, also equipped with the hanging member at substantially the center of the suction table, may be configured so as to hold the hanging member by said pressing member, further,
A main pipe is connected to the connecting pipe attached to the blower on the suction table via a flexible pipe, an air blocking member is connected to the connecting pipe, and the air blocking member is mounted on the main pipe,
The main pipe may be shut off by the air shutoff pipe by lowering the suction table.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, since the head structure moves orthogonally to the suction table, if the suction table in the portion of the head structure through which the tool is passed does not come into contact with the tool when the tool passes. Without damaging the board on the suction table with the tool, lower the suction table by the width of the part where the tool passes and separate it from the work plate, and in other parts, pick up the work plate with the suction table and position it With such a configuration, the NC program for manufacturing the scraps, the labor for manufacturing the scraps, and the place for storing the scraps are unnecessary, and the cost can be significantly reduced and the delivery time can be shortened.

When 1b is not used, it is also possible to use a waste board as usual.

In the above embodiment, the air cylinders 11a and 11b are mounted on the table plate 10 so as to raise the suction block 12, but a spring may be used instead of the air cylinder.

Further, the two hanging members 19a and 19b are mounted from the suction block 12, but the hanging members are mounted at substantially the center of the suction block 12, bearings are respectively mounted on both sides thereof, and the pressing members 21a and 21b are the hanging members. May be configured to be sandwiched between the bearing 2 and
Wheels may be used in place of 0a and 20b, and an example in which a large number of suction holes are provided in the board 14 on the upper surface of the suction table 12 is shown, but a board or suction pad made of a material with good air permeability, etc. May be used.

[0015]

As described above, in the suction table of the NC router according to the present invention, the suction table is lowered only at the tool passage position of the head of the head structure to separate from the work plate. When processing a plate, the tool does not damage the board on the upper surface of the suction block even if the tool goes below the lower surface of the work plate. It can be placed on top of it, therefore NC program for making scraps, time and effort to make scraps, and place to store scraps are not required, and it is possible to significantly reduce costs and shorten delivery time. There are advantages.
