Title:

TRANSFER FEEDER

Document Type and Number:

WIPO Patent Application WO/1994/021404

Kind Code:

A1

Abstract:

A transfer feeder comprises a pair of lift beams (9) juxtaposed to extend in a direction of work transfer, a lift mechanism (10) for vertically driving the pair of lift beams, a plurality of pairs of cross bar carriers (15) connected to the pair of lift beams to be spaced from one another in the direction of work transfer and movably mounted thereon, cross bars (16) mounted transversely between the facing cross bar carriers and provided with work suction means (19), and a feed mechanism (22) for driving the cross bar carriers in a feed direction, at least said lift mechanism being driven by a servomotor (11). With this arrangement, the lift beams are driven by the servomotor, so that the cross bars can be moved in an optional motion pattern and various motion patterns can be readily obtained. In addition, a specific cam is not necessary for each motion pattern, so that it is possible to simplify the drive mechanism.
