The position is higher than the pressing pin 10b. Therefore, the pins (hereinafter, referred to as interference pins) on the load concentration portion on the boundary line between the product and the waste or near the cutting line among the pressing pins 10a are removed.

When the interference pin is removed in this manner, the pressing pin 10a lowers the upper substrate 18 and returns to the upper pressing pin holding hole 20, and inserts the upper locking pin into the through hole 40 to lock the upper substrate 18. Then, the die-cut paperboards 30 stacked to an appropriate thickness are positioned on the raised lower support plate 26 and pressed, whereby the pressing pins 10 supported on the upper substrate 18 are pressed.
“a” serves as a die, and the pressing pins 10 b held on the lower substrate 16 act as a punch, and can separate the product part 32 and the waste part 34 of the die-cut paperboard 30. Then, after the separation of the product and the debris is completed, the extracted interference pin is returned to the original position, and another type of product part and waste part are separated.

As described above, the operation of removing the interference pin according to the shape of the product part and returning the interference pin to the original position requires several tens of interference pins depending on the shape of the product part, and thus requires time and labor. It was a task, and it was desired to improve the task of removing the interference pin and returning it to its original position.
