摘要

A power supply control device that controls consumption currents that are supplied from power supply devices in a component supply device in which multiple tape feeders are replaceably installed, the device including: a total consumption current measuring section that obtains, based on measurement, a total consumption current by adding actual consumption currents which are supplied to a plurality of tape feeders; and an overcurrent protection section that causes a specific tape feeder, which is in an operation state, to transition to a stop state or a standby state, in a case of an overcurrent state where the total consumption current exceeds an output current capacity of the power supply device. Accordingly, even though the overcurrent state occurs during setup changing work in which the multiple tape feeders can operate, the overcurrent state is rapidly canceled, and thus a protecting function is improved.

說明書

In the power supply control device 2C of the component supply device 1 according to the fourth embodiment, the power supply device 41 or 42 and the tape feeder 10 are connected to each other with the drive power supply line 35, through which a drive current is supplied to be consumed by the driving devices (the first feeding motor 131 and the second feeding motor 141) and on which the drive power switch 54 that shuts off the drive current is interposed, and the control power supply line 36 through which the control current is supplied to be consumed by the control device 17. The overcurrent protection section 24C controls the tape feeder 10 such that the tape feeder is in the standby state and the operation state through the opening and closing control of the drive power switch 54.

Accordingly, since the control devices 17 continue operating without the stop state, the tape feeders 10 has high reliability of control. In addition, there is no need to complicatedly repeat an initial process executed when the control device 17 starts up.
