TRANSFER UNIT FOR TRANSFERRING PRODUCTION COMPONENT PARTS ON AUTOMATIC PRODUCTION MACHINES

摘要

A transfer unit (1) for a production machine (2), wherein component parts (3) are fed to a first station (4) at a speed vl, and products (7) are fed to a second station (5) at a speed,v2 " differing from vl; the transfer unit (1) has at least one pickup head (10; 11) operated by an actuating unit.(17) to.cyclically pick up at least one component part (3) ' at the first station (4), and to transfer it onto a relative product (7) at the second station (5); and the actuating unit (17) imparting to the pickup head (10; 11), at each cycle, a variation in speed between speeds vl and v2 by means of a mechanical transmission (19a, 19b) with a variable velocity ratio, and. an electronically regulated, variable-speed motor (18a,- 18b) connected in series to the mechanical transmission (19a, 19b).
