Sensor-Timed Sorting Line (2D)

Parts ride a conveyor past a photoelectric sensor, and a pneumatic diverter downstream has to fire inside a narrow timing window to push each one off the line — the classic sense-schedule-actuate sequence behind real sorting and pick-reject stations. This top-down 2D simulator drives the belt, sensor beam and diverter from an actual discrete-event schedule: every part's sensor-trigger time, travel time to the actuator and the actuator's own delay and dwell are tracked explicitly, and a live strip chart plots the fire/dwell interval against each part's physical transit window so a mistimed setting shows up as a visible miss on two synchronized panels, not just a number. Tune belt speed, actuator response delay, pusher dwell time, spawn rate and simulation speed, and read live throughput and sort-accuracy off the same numbers a line engineer would tune against.
