In many presses, blanks must be fed one by one to a lower die. In this case, the blank materials are usually stacked one on top of the other, and are gripped and fed one by one by gripping means such as a suction device. Since the blanks are stacked as described above, in some cases two blanks may be held at the same time. To detect these two images.

Conventionally, one or two sheets were measured using a plate thickness detection device such as magnetic steel.
I was trying to judge whether the number was more than one. However, this conventional method for measuring plate thickness detects the thickness by contacting the edge of the blank material, which has the disadvantage that it cannot be measured in the case of irregularly shaped blank materials.

A keyboard 8 is connected to the CPU 7 so that the operation of the CPU 7 can be changed by external operation. The CPU 7 also compares the output of the A-D converter 5 with a reference value stored in advance in the storage circuit 6.
It has a comparison section 9 that determines whether the output of the A-D converter 5 matches, exceeds, or is below a reference value, and outputs the result.
Each relay 11, 12, 13 is operated by the output of the seed via the driver 10. The relay 11 operates when there is an overload, that is, there are two or more sheets, the relay 12 operates when the blank material is normal, and the relay 13 operates when the blank material is lighter than the normal one.
