Title:
BRAKE CONTROL APPRATUS AND SUBSTRATE PRODUCTION LINE
Document Type and Number:
WIPO Patent Application WO/2021/240697
Kind Code:
A1
Abstract:
This brake control apparatus is provided with an electric motor, a power supply device, a plurality of electric circuits, a brake device, and a restriction device. The electric motor moves an article conveyance device that conveys an article to a predetermined substrate work machine in a substrate production line where a plurality of the substrate work machines for performing predetermined substrate work on a substrate are disposed in a line. The power supply device supplies driving power of the electric motor. The plurality of electric circuits transmit driving power from the power supply device to the electric motor. The brake device, when stopping the electric motor, generates braking force in the electric motor by consuming regenerative energy of the electric motor among the plurality of electric circuits. The restriction device restricts generation of braking force by switching from a closed circuit state in which target electric circuits of the plurality of electric circuits between the electric motor and the brake device after the electric motor has been stopped are closed to an opened circuit state in which the target electric circuits are opened.
