Claims13
A conveyor control apparatus, comprising:
- a rotary mechanical means for generating a first set of electrical signals, a second set of electrical signals, and a third set of electrical signals in correlation with the movement of a conveyor having a plurality of on-loading stations and a plurality of off-loading stations;
- a counting means for counting said first set of electrical signals;
- a decoding means responsive to said counting means for producing electrical outputs;
- a gate means responsive to the coincidence of said electrical outputs and said second set of electrical signals;
- said counting means and said decoding means including reset means responsive to said third set of electrical signals;
- on-loading control indicator means responsive to said gate means;
- off-loading indicator means responsive to said gate means;
- said on-loading control indicator means associated with said plurality of on-loading stations whereby each member of said plurality of on-loading stations may receive a sequence of signals by which the effective times of on-loading may be indicated in order that consignments on-loaded at such times may reach their respective ones of said off-loading stations during periods of activation of said off-loading indicator means;
- and said off-loading indicator means associated with said plurality of off-loading stations whereby each member of said plurality of off-loading stations may receive a sequence of signals by which the effective times of off-loading may be initiated.
