Abstract:
An apparatus for assembling a spring coil assembly, comprising:a main conveyor adapted to convey a plurality of coils in a direction of travel along a longitudinal axis; an assembler which is operable to intertwine a plurality of rows of coils into a spring coil assembly; and a transfer station configured to simultaneously move a plurality of coils, defining a row of coils, from the main conveyor into the assembler, the transfer station including: a plurality of pusher arms, each pusher arm including a gripper which is operable to grasp an individual coil located on the main conveyor; a carriage supporting the pusher arms; and an actuator for shifting the carriage in a direction substantially parallel to the longitudinal axis so that the row of coils carried by the grippers is displaced in the direction of travel of the conveyor relative to an adjacent row of coils.
