Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate transfer device for transferring a substrate on an upstream device to a work table and a substrate on the table to a downstream device.

[0002]

2. Description of the Related Art As a conventional technique of this kind, there is one disclosed in Japanese Utility Model Application Laid-Open No. 63-77918 filed by the present applicant.

However, since the driving source of the feeding member is the AC motor, it cannot be dealt with when the substrate is to be conveyed in the opposite direction to the conventional one due to the work line organization.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it possible to transfer a substrate in both forward and reverse directions.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides a substrate transfer apparatus for transferring a substrate on an upstream side device onto a work table and a substrate on the table to a downstream side device, wherein A feed member having a pair of feed claws that come into contact with the rear ends of the respective substrates on the work table, a drive source that reciprocates the feed members along a guide, and a conveyance that conveys the substrates to the right by the feed claws. A storage device that stores a transport program that transports to the left in the same manner as the program, a selection device that selects a desired program from both programs stored in the storage device, and a substrate according to the program selected by the selection device. And a control device for controlling the drive source so as to convey the sheet in a predetermined direction.

[0006]

With the above configuration, the control device controls the drive source based on the program when, for example, the program for transporting the substrate to the right is selected by the selection device from the two programs stored in the storage device. The feed claws of the feed member are brought into contact with the upstream side device and the rear end of the substrate on the work table to convey the substrate rightward.

Further, when a program for transporting the substrate to the left is selected by the selecting device, the drive source is controlled based on the program so that the feed claw of the feeding member is moved to the upstream side device and the substrate on the work table. The substrate is conveyed to the left while being brought into contact with the rear end of the substrate.
