Automatic Rotary Table Assembly Machines — Delay and Make Right or Combine and Reject

Summary

Many automatic assembly machine manufacturers maintain the philosophy that once a machine is started it should continue indexing until a serious jam occurs. This concept is challenged and illustrations will be given of machines incorporating control systems which delay the cycle until any misfeeding station clears. This is shown to be a superior method. The ‘unjammable’ jam is recognized and the operator will be summoned. Not only are reject levels reduced but output of good components is increased.
