Abstract: An object of the invention is to provide a zone controller and a conveyor device which facilitate identification of a defective part when a defect occurs in a distributed control type conveyor device. There is provided a zone controller (10) which is used for a conveyor device (1) in which a plurality of zone conveyors (2) are arranged in series, which manages one or a plurality of the zone conveyors (2) to control an operation thereof, and which is configured to receive a signal from a different zone controller (10) and transmit a signal to the outside.

Abstract: An article storage device for storing a plurality of pallets and having a plurality of storage compartments includes a conveyor for conveying the pallets, the conveyor being divided into a plurality of control zones corresponding to the respective storage compartments and having controllers in the respective zones. At least the controllers in the zones between the both end control zones each have a motor functioning also as an arrival detector, a RAM, and a communication circuit, the motor being for detecting a pallet being entering the home control zone, the RAM being for memorizing information indicating whether a pallet exists in the home control zone, and the communication circuit being for transmitting the information to the controller in the downstream zone. The controllers each contain a program to move up the pallet to the downstream zone so as to store the pallet.

Abstract: A motor driver for drive-controlling a brushless motor being provided with a delay circuit that detects the motor pulse. When a stop signal is inputted, a transistor is activated, which in turn activates an electric brake to brake the brushless motor, while at the same time, the motor pulse detected by the motor driver is inputted to the delay circuit. After the stop signal is inputted, the motor pulse declines, which is detected by the delay circuit to activate the electromagnetic brake. The delay circuit is provided on the driver substrate for the motor driver.
