Flow Line Counter Incorporating Programmed Reversal Circuitry
US Patent:
4081661, Mar 28, 1978
Filed:
Sep 13, 1976
Appl. No.:
5/722384
Inventors:
John R. Durbin - Kirkwood MO
International Classification:
G06M 700, G06M 314
US Classification:
235 92EV
Abstract:
For counting objects moving along a line of flow in a forward or reverse direction, a system utilizes upstream and downstream sensors and a logic subsystem to provide pulse signals to a counter. The logic subsystem produces an upcount or downcount signal only after a sequence of system states is consecutively achieved. Before a count signal is produced an intervening state-confirming signal is required. When such confirming signal is followed by a count-producing signal the logic subsystem automatically resets to a reverse flow condition. Thus, neither vibrations nor reversal of object flow at any point will cause a false count.
