DEVICE WHICH RECOGNIZES AND COUNTS CASTINGS IN CONVERGING PROCESSING CYCLE Russian patent published in 1998 - IPC

FIELD: computer engineering. SUBSTANCE: device has detectors, counters, XOR gate, NOT gates, AND gates. Outputs of one group of AND gates are connected to corresponding counters. In addition device has two flip-flops which central inputs are connected to corresponding AND gates, which second input is connected to inverting output of another flip-flop. Second input of first AND gate is connected to first NOT gate. Second input of second AND gate is connected to second NOT gate. Detectors provide detection of casting. First detector is located on one side of carriage unload and is connected to first NOT gate. Second detector is located on another side and is connected to second NOT gate. Third detector is located after carriage unload in center of processing cycle which corresponds to first detector and is connected to third NOT gate. Fourth detector is connected to fourth NOT gate. Outputs of two first detectors are connected to reset inputs of flip-flops through AND gate. Inputs of XOR gate are connected to outputs of two latter NOT gates. Outputs of first NOT gate and XOR gate are connected through AND gate to inputs of two AND gates for recognition of pairs of branches. One inputs of AND gates are connected to third NOT gate for odd numbers in counters and to fourth NOT gate for even numbers in counters. Other inputs of AND gates are joined in pairs and connected to inputs of AND gates for recognition of pairs of branches. EFFECT: possibility to search manufacturing source for each casting and count castings independently in branches. 2 dwg
