Title:
PUNCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/024488
Kind Code:
A1
Abstract:
With conventional punching devices, there has been a problem that roll elements made of paper are required in order to convey the workpiece, thereby making it difficult to reduce manufacturing costs. This punching device 10 principally comprises: a conveyance mechanism 13 for shifting a workpiece 11 on the upper surface of a carrying section 12 in a feeding direction; a die set 14 for supporting the conveyance mechanism 13; a punch mechanism 15 provided above the conveyance mechanism 13 for punching a punch hole 51 into the workpiece 11; and a controller 16 for controlling operation of the punching device 10. The conveyance mechanism 13 is provided with a first feeding unit 13A and a second feeding unit 13B for intermittently feeding the workpiece 11. Due to this configuration, the workpiece 11 can travel on the upper surface of the carrying section 12 without the use of paper roll elements for conveyance, and as a result, manufacturing cost are considerably reduced.
