Abstract
A control arrangement for an accumulating conveyor having a plurality of zones includes an electrically-powered sensor in each zone, and a logic circuit associated with each sensor, each logic circuit comprising a first input, a second input from the sensor of its zone, a first output which sends a signal to the activator for that zone, and a second output to send a signal to the input for the next zone.
Claims6
A control system for an accumulating conveyor having a plurality of accumulation zones, and an activator for each zone, comprising:
- an electrically-powered sensor for each accumulation zone of the conveyor;
- and
- a logic circuit associated with each electrically-powered sensor, each logic circuit having control signal inputs and control signal outputs, consisting only of:
- a. a first control signal input;
- b. a second control signal input coming from the electrically-powered sensor with which that logic is associated;
- c. a first control signal output which is adapted to transmit a signal to the activator for that zone;
- and
- d. a second control signal output which is adapted to transmit a signal to the input for the next zone.

- c. a first output which is adapted to transmit a signal to the activator for that zone;
- and
- d. a second output which is adapted to transmit a signal to the input for the next zone, and further comprising an "or" function in each logic circuit, wherein said "or" function receives signals from the first and second inputs and, if there is a signal in either of the inputs, transmits a signal to the first output for that zone i order to cause the activator for that zone to operate.
