Abstract

PURPOSE:To steadily take out cut-out material by providing a defector for magnet position and a phototube for detecting an absorption error and sliding the taking out action back and forth when taking out cut-material by making a magnet absorb with a wire-cut electric discharge machine. CONSTITUTION:When a motor 6 rotates and the first dog 16b is detected with the first detector 15b, the motor 6 stops and an air cylinder 11 lowers and a magnet 4 absorbs a cut-out material 2. Thereupon if an absorption error occurs, a phototube 17 detects that it is not absorbed and by this detected signal the motor rotates reversely and returns in the original direction and stops at the second position where the second detector 15a detects the second dog 16a, that is, the position slid forth about 10 deg. from the right above so as to perform absorption work. Also if an absorption error occurs in the second position, the third detector 15c stops at the third position to detect the third dog 16c, that is, at the position slid back about 10 deg. from the right above so as to perform absorption work.

[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.

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).
