Conveyor control circuit for use at a junction of conveyors at which articles move from one conveyor to another or between a number of conveyors. Speed signals from conveyors whose speeds are dictated by conditions elsewhere in the system are summed to produce a 'net flow signal' which is preferably corrected by the addition of a signal from a sensor at the junction, whose sensitivity may be adjusted in accordance with the net flow signal so that the correction is greater when the net flow towards or away from the junction is greater. The controlled conveyor may be used to move articles to or from a reservoir device. Additional speed correction may be applied if the sensor signal is outside a range which varies in size with the net flow signal.

Production line flow control

Packet handling apparatus includes a conveyor for moving packets in line from a delivery station and a reversible accumulator for receiving batches of packets from or returning batches to the conveyor according to whether supply exceeds demand or vice versa. Gates for supplying movement of packets on the conveyor are provided at the exit from and entry to the accumulator. The conveyor section adjacent the accumulator is separately drivable so that it may be temporarily stopped to create a gap between packets for insertion of the exit gate prior to transferring a batch of packets to the accumulator. Guides may be provided upstream and downstream of the accumulator for moving packets from a flat to an upright condition and vice versa, respectively.
