A method for controlling an overhead transportation system has a number of travelling holders on a track which carry baskets of workpieces from one station to another under the control of a computerised system

摘要

The workpieces (11,12,13) of varying types (14,15,16) in groups (17,18,19) in baskets (20) are transported from the stations (S0-S6) by carriers (21,22,23) on a track (26) for various operations of varying duration. A computerised system (30) controls the drives (28) and lifting mechanisms (29) of the transporters to suit the various processes.
