A work transfer conveyor (Photo 1) with an auto-pause function for three stations is discussed here as an example of LCA mechanism design. A perspective view of this LCA mechanism is second from the right, bottom row in "Typical Applications of Standard Components: 1" on the center-page spread of the "FACE-FA Mechanical Standard Components Catalog."

(1) Main components of the work transfer conveyor

This simplified automated system (LCA) for positioning and transferring incoming workpieces on a conveyor can be used as an auxiliary system for a series of operations including, for example, feeding, positioning/inspection, and pre-ejection pauses. The components of this system are as follows:

1. Flat belt driven mechanism and belt tension adjustment mechanism
2. Motor torque transmission chain mechanism
3. Work positioning mechanism
4. Work detecting and drive controlling sensor system

(2) Points in work transfer conveyor design

Some creativity has gone into the following points to realize a low-cost, assembly-, adjustment-, and maintenance-friendly LCA system:
