NONJAM LEAD-ON TRACK FOR CONVEYOR SYSTEMS |
摘要 |
Jamming of article carriers on the lead-on ramp of a track causes displacement of the ramps to retracted positions and stoppage of the conveyor from which the carriers are suspended. The ramps are pivotally mounted by crank elements projecting forwardly from the track and are yieldably held in operative and retracted positions by detents.
