Abstract

This article describes a process and mechanics for automatically loading a cartridge top and spring sub-assembly into a daisy wheel and cartridge bottom sub-assembly. (Image Omitted) Fig. 1 is an exploded view in perspective showing the cartridge bottom and daisy wheel sub-assembly. Figs. 2 and 3 are front and side views, respectively, of the mechanism for performing the loading process. The cartridge top is automatically fed from a vibratory feeder (Image Omitted) bowl (not shown) and positioned in a spring-loaded fixture directly above the leaf spring that is held in position by a gripper. Referring to Figs. 2 and 3, a pick-up head consisting of two electromagnets and a vacuum cup pushes down on the cartridge top until contact is made with the leaf spring. The electromagnets are energized, and the vacuum is turned on.
