Reference numeral D denotes a work setting means for restricting the supply position of the work material W. Reference numeral 20 denotes a pair of bearing metals 21 provided on the left and right sides inside the table 3 and a pair of bearing metals 20.
Rearward turning arm 2 rotatably supported by
Reference numeral 2 is a long ruler plate disposed on the left and right so as to connect the free ends of the rotating arm 21. This ruler plate 22 tends to descend due to its weight. E is a cam plate-shaped passive member attached to the back surface of the ruler plate 22.

The passive member E is composed of a first passive piece 23 and a second passive piece 24, as shown in FIG.
The first passive piece 23 has low passive parts a and b at both left and right ends and a high passive part c at an intermediate part. The second passive piece 24
Has a length substantially corresponding to the high passive part c of the first passive piece 23 and forms a low passive part d over the entire length.

Numeral 25 is one lever-like switching piece disposed at one end of the second passive piece 24, which is in a tendency to hang down at all times.
The gap 25 between the first and second passive pieces 23, 24 is opened. Reference numeral 26 denotes the other lever-shaped switching piece disposed at the other end, which normally tends to rotate counterclockwise and closes the gap 25. The switching pieces 25 and 26 connect the passive portion d of the second passive piece 24 and the passive portions a and b of the first passive piece 23.

F is an operating member provided on the side of the left and right moving base 6 corresponding to the passive member E. This operating member F is a mounting stay 27 fixed to the left and right moving base 6 and a rolling member provided on the mounting stay 27. It is configured by the moving roller 28. When the rolling rollers 28 come into contact with the low passive parts a, b, d, the ruler plate 22 is projected onto the table 3. Further, when it comes into contact with the high passive portion c, the ruler plate 22 is immersed in the table 3.

The structure of the groove processing machine according to one embodiment is as described above, and the cutting process is performed as follows. In the first state, the left-right movement base 6 is at the starting end position and is on standby. Cutter 1 at this position
0 corresponds to the position where the processed material on the table 3 is not attached. The pressing plate 19 is retracted to a position above the table 3. (See Figure 2)

In this state, the processed material W is placed on the table 3.
Is supplied, and the rear end thereof is brought into contact with the ruler plate 22 for positioning. If the processed material W has a short length, it is set side by side in the left-right direction. After the setting is completed, the pressing plate 19 is moved downward to clamp the workpiece W. On the cutting head 8 side, the cutting position of the cutter 10 is set by adjusting the inclination and the front-rear adjustment.

When each of the above operations is completed, the cutter 10 is rotated and the reversible motor Ma is driven to move the left and right moving base 6 toward the other end. By this movement, the rolling roller 28 moves from the low passive portion a to the high passive portion c. Therefore, the ruler plate 22 moves down and sinks into the table 3. Therefore, the cutting process can be smoothly performed without interfering with the ruler plate 22.

The groove processing of the work material W is performed while the rolling roller 28 is engaged with the high passive portion c, and is finished. When the left-right moving base 6 reaches the other end position, the pressing plate 1
The clamped product 9 is released, and the processed product is carried out from the table 3. At the other end position, the ruler plate 22 projects above the table 3. On the other hand, the reversible motor Ma reversely rotates to move the left-right movement base 6 toward the starting end position.

During the return traveling, the rolling roller 28 is engaged with the lower passive portion d of the second passive piece 24 by the action of the switching piece 26. Therefore, the ruler plate 22 is held at the protruding position, and the next processed material W can be set at the time of this return. Immediately before reaching the starting end, the other switching piece 25 acts, and stably holds the ruler plate 22 at the protruding position.

When the cutting process is completed before the first passive piece 23 is escaped from the high passive portion c, the rolling roller 28 is returned to the starting end direction while being in contact with the high passive portion c. Will be done. Therefore, in this case, the ruler plate 22 remains immersed, and the next processed material W cannot be set immediately upon returning.

In the above-described embodiment, the cutter 10 is located on the upper surface side of the work material W and is cut.
For this reason, the ruler plate 22 is recessed downward and retracted. However, in the case where the cutter is positioned on the lower surface side of the processed material W to perform the cutting work, it is advantageous to retract the ruler plate upward.

In this case, when the cutter 10 is at the starting end position as shown in FIG.
When the ruler plate 22 is set in the projecting position by abutting on the high passive portion h in 3a, and when it is in the intermediate position, the rolling roller 2
8 is brought into contact with the lower passive portion j of the passive piece 24a and the ruler plate 22
May be designed to be set to the upper retracted position. In this case, the lower end of the ruler plate 22 is used to process the workpiece W.
Set.

Further, although the ruler plate 22 of the one embodiment can be lifted and lowered by the rotating arm 21, it may be slidably supported by a vertical linear guide (not shown).
Although not particularly described in the embodiment, when the ruler plate 22 is long and heavy, it is recommended to take measures to reduce the load on the rolling rollers 28. Well-known means such as a balance weight and a spring are used for this.

[0027]

As described above, the work set device according to the present invention can accurately perform the raising and lowering operation of the ruler plate without using a positive drive device or special electric operation means. Therefore, the excellent effect that the structure can be simplified and the cost can be reduced rationally is exhibited.
