ABSTRACT:
A loader (10) for a forming machine (12) is disclosed as including a horizontally elongated transfer beam (46) supported by a linkage (52) and moved by a dual output cam unit (62). A first output (64) of the cam unit (62) is connected to an intermediate portion (50) of the beam (46) and a second output (66) thereof is connected to the linkage (52) to cooperatively move the beam (46) vertically and horizontally in a closed path such that workpieces (30) are moved into alignment with a work station (22) of the machine (12) for forming and out of alignment therewith after the forming is completed. The cam unit (62) has first and second cams (68,72) that move associated first and second followers (200,224) to move the first and second outputs (64,66) which respectively actuate horizontal and vertical movement of the transfer beam (46). A vertical slide connector (210) connects the first follower (200) with an intermediate portion (50) of the transfer beam (46), and an actuating link (92) connects the second follower (224) with one end lever (78) of the linkage (52) to actuate the vertical transfer beam movement. A connecting link (88) of the linkage (52) connects the one end lever (78) with another end lever (80) to provide coordinated support of the opposite ends (48) of the transfer beam through roller slide connections (86) that allow the transfer beam (46) to move horizontally under the impetus of the first output (64) of the cam unit (62).
