Title:
CONVEYOR DEVICE, ZONE CONTROLLER, MOTOR CONTROL DEVICE, AND DEVICE GROUP CONTROLLED BY MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/147011
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a conveyor device and a zone controller in which regenerative current can be effectively utilized and a stable actuation can be ensured. The interior of the zone controller (10) is divided into an actuation circuit part (21) and a power supply circuit part (22). The power supply circuit part (22) is provided with: a current input terminal (30) which is connected to the power supply and which receives power from the power supply; an earth-side terminal (31); and an auxiliary power terminal (32). The power supply circuit part (22) has a backflow prevention means (35) such as a diode, and a capacitor (36). Current flowing from the power supply device (40) through the plus-side power line (46) is fed to the actuation circuit part (21) and causes a motor (4) to rotate. Since the regenerative current is a current flowing in the reverse direction with respect to the backflow prevention means (35), the regenerative current does not return to the power supply side, and the auxiliary power terminal (32) reaches a high-potential state. When the motor (4) of an adjacent zone is driven, a regenerative current generated in the zone conveyor (2) is consumed in the adjacent zone conveyor (2).
