SHUTTLE CONVEYOR, CIRCUIT-SUBSTRATE WORKING MACHINE, AND CIRCUIT-SUBSTRATE WORKING SYSTEM

摘要

Utility of a circuit-substrate working machine including a substrate conveyor device and a shuttle conveyor designed to shift a circuit substrate in a direction intersecting a conveying direction is improved. Based on transmission of a deliverable-state advance notification signal for one of conveyor lanes of an upstream printer, a movable conveyor lane of an intermediate shuttle conveyor is moved to a position continuous to the one conveyor lane. The circuit substrate is delivered to the movable conveyor lane in a state in which the movable conveyor lane is located at a circuit-substrate receiving position, a receivable-state advance notification signal is produced for a receiving lane for receiving the circuit substrate supplied from one of conveyor lanes of a downstream printer which has transmitted a deliverable-state advance notification signal, and a receivable-state signal and a deliverable-state signal are obtained. The circuit substrate is then delivered to the receiving lane.
