Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a blank material conveying device which can convey a blank material whether it is a magnetic blank material or a non-magnetic blank material.

[Prior Art] From a stack in which many blanks such as steel plates are stacked,
As a device for taking out blank materials one by one and supplying them to the press, a blank material conveying device as shown in FIG. 3 is generally used.

The blank material conveying device conveys the stack b sent by the skid pallet a to the lower side of the vacuum device e after removing oil and the like by the air nozzle c and washing the stack b from the stack b to the vacuum cup f of the vacuum device e. The blank material g is adsorbed on the magnet conveyor h ′ as a magnetic blank material transporting device h driven by a motor p, and further transported, and a cleaning is provided with a feed roll j driven by a motor i and a brush roll k. After being sent to the apparatus m and cleaned by the cleaning apparatus m, it is sent to a press (not shown) via the supply conveyor n.

In the figure, q is a magnet of the magnet conveyor h '.

[Problems to be Solved by the Invention] However, in the above-mentioned blank material conveying device,
When the blank material g is a magnetic material such as a steel plate, the magnet conveyor h ′ can attract and convey the blank material g to the magnet q via a belt, but when the blank material g is a non-magnetic material such as aluminum. Since the magnet q cannot be attracted to the magnet, it is impossible to convey the non-magnetic blank material using the magnet conveyor h '.

Therefore, conventionally, when pressing a non-magnetic blank material, the non-magnetic blank material is manually taken out from the stack b and fed to the cleaning device m, which hinders automation of the blank material conveying device and causes the operation. Besides increasing the cost, it is not preferable in terms of safety.

In addition, to automatically convey non-magnetic blank materials,
It is conceivable to separately install the non-magnetic blank material conveying device adjacent to the device shown in FIG. 3 as a dedicated line, but there is a problem that the equipment becomes large and uneconomical.
