Abstract

There is provided a conveying device that reliably discharges only scrap when simultaneously conveying the scrap and a pressed product without sacrificing cycle time. A conveying device for use in press forming includes: a conveying part that holds a product part and a scrap part of a workpiece after a cutting process, and conveys the product part and the scrap part to a next process; a nozzle part that is provided in the conveying part, and discharges compressed fluid toward the scrap part; and a controller that performs a control to release holding of the scrap part during conveyance of the workpiece and to blow compressed fluid toward the scrap part.

First claim

What is claimed is:

1. A conveying device for use in press forming, the conveying device comprising:
a conveying part that includes respective holding parts for holding a product part and a scrap part of a workpiece after a cutting process, and conveys the product part and the scrap part to a next process;

a nozzle part that is provided separately from the holding parts in the conveying part, and discharges compressed fluid toward the scrap part; and
a controller that performs a control to release holding of the scrap part during conveyance of the workpiece and to blow the compressed fluid toward the scrap part.

2. The conveying device according to claim 1 ,
wherein the nozzle part is disposed so as to be directed toward a portion on a downstream side or an upstream side in a conveying direction of the scrap part with respect to a gravity center position of the scrap part.

3. The conveying device according to claim 1 ,
wherein the conveying part holds and conveys the scrap part at a position lower than the product part.

4. The conveying device according to claim 1 ,
wherein the nozzle part is disposed so as to be directed toward a portion on a downstream side or an upstream side in a conveying direction of the scrap part with respect to a gravity center position of the scrap part, and
the conveying part holds and conveys the scrap part at a position lower than the product part.
