いという問題があった。[Problems to be Solved by the Invention] Originally, the cutting material (2) has various shapes, and when cutting out the material (1) with a wire-cut electric discharge machine as shown in Fig. 3, the cutting is performed using an initial It starts from the hole (H) and ends at the position point (A) that goes around the required shape. In this case, whether the position point (A) is directly above the lower guide (3) or
The center of gravity of the cutout (2) is not necessarily directly above the lower guide (3). Therefore, when the magnet (4) stops directly above the lower guide (3), the magnet (4) may barely cover the cutout (2), as shown in Figure 4B. In such a case, there was a problem in that no matter how much the magnet (4) was moved up and down directly above the lower guide (3), the cutout material (2) could not be attracted.

である。[Embodiment] FIG. 1 is a side view schematically showing an embodiment of the present invention, partially in cross section. In the figure, (15) is a detector for detecting the angle of the spline shaft (10), which includes a first detector (15b), a second detector (15a), and a third detector (
15c). (16) is the dog of the detector (15) attached to the shaft of the gear (8), and the first dog (18) corresponding to the detector (15) is shown in FIG.
b) Consisting of a second dog (lea) and a third dog (16c), the first dog (18b) is the first detector (15b)
The position detected by magnet (4) is exactly when the lower guide (3) is detected.
) so that it is directly above it. Also, the second dog (
lea) detected by the second detector (15a) is shifted by about 10 degrees before that, and the third dog (16c) is detected by the third detector (15a).
The angle detected by the detector (15c) is later shifted by about 10 degrees. (17) is a phototube, which is installed at the height of the lower surface of the magnet (4) by a holder (not shown). Other symbols are the same as those explained in FIG.

4図Bの状態)。Next, this effect will be explained. When the cutting work for wire cutting is completed and the cutting material (2) is supported on the lower guide (3), the motor (6) rotates and the rotational force is transferred to the gear (7).
The rotation of the gear (8) is transmitted to the spline shaft (10) via the spline bearing (9),
Rotation of the spline shaft (10) turns the rotary arm (5) and moves the magnet (4) fixed to the rotary arm (5). When the first dog (ieb) attached to the spline bearing (9) is detected by the first detector (15b), the motor (6) stops rotating and the magnet (4)
stops at the first position directly above the lower guide (3) (state shown in FIG. 4B).

下降により切抜材(2)の吸着動作を行う。Next, the air cylinder (11) descends and connects the connecting rod (12).
), connecting plate (13), bearing (14), rotating arm (5)
The magnet (4) is lowered until it comes into contact with the material (1). After this, when the air cylinder (11) rises again,
Normally, the magnet (4) attracts the cutout (2) and the cutout (2) rises together, but if an adsorption error occurs,
The magnet (4) rises without attracting the cutout (2), and the rotation of the motor (6) rotates the rotary arm (5) via the spline shaft (10). However, at the same time, a photocell (1) was installed at the height of the bottom surface of the magnet (4).
7), it is detected that the magnet (4) is not attracting the cutting material (2). This detection signal causes the motor (6>
rotates in the opposite direction again and returns to the original direction, and this time the second detector (
15a) detects the second dog (lea), that is, the magnet (4) stops at a position shifted approximately 10 degrees from directly above the lower guide (3) to the front (the state shown in Fig. 4C). ). Next, the air cylinder (11) is lowered to perform the same suction operation for the cutout material (2) as described above. If a suction error occurs at this second position as well, if the phototube (17) detects this, the motor (6) will reversely rotate and return to the original direction as before, and the third detector (15c) is the third dog (16
c), that is, the magnet (4) stops at a position shifted approximately 10 degrees backward from directly above the lower guide (3) (state shown in the fourth diagram). Therefore, the air cylinder (11) is lowered to suck the cutting material (2).

) By repeating the attraction operation while changing the position of the magnet (4), the possibility that the cutout material (2) will be attracted by the magnet (4) increases dramatically.

Although the case where the magnet (4) is rotated is shown, it is also possible to transmit the rotation of the motor (6) to a ball screw to shift the position of the magnet (4) in a linear direction.
