Abstract

This article describes a dual-function spring which facilitates robotic assembly. Spring 2, shown in both Figs. 1 and 2, is a flat rectangular shaped piece of spring steel which applies pressure to conform a sheet for printing against platen 4 in a printer. In Fig. 1, it provides feed pressure by biasing feed roll arm 6 which urges feed roll 8 against platen 4. In Fig. 2, a spring having the same configuration urges bail 10 with roller 12 against platen 4. Advantages of such a dual-purpose spring design include a greater ease of manufacturability since there are no spring loops to be hooked and thus no down time to clear tangles. The springs may be stacked for automatic assembly access, and minimum tooling changes are required for different applications.
