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

The power supply control device 2A of the component supply device 1 according to the second embodiment operates based on the operation flow of the first embodiment illustrated in FIG. 4, and a part of operation is different therefrom. Hereinafter, an operation different from that in the first embodiment will be described, and thus the description of the same operation will be omitted. In the total consumption current measuring step S3 in FIG. 4, the total consumption current measuring section 21A of the second embodiment receives and acquires information of a total consumption current from the collective current measurement section 53.

In addition, in step S10, the overcurrent protection section 24A of the second embodiment determines, in accordance with a preset priority, the tape feeder of the tape feeders 10 which are in the operation state such that the tape feeder 10 transitions to the stop state or the standby state. In the second embodiment, since there is no individual measured values of the consumption current, it is not possible to identify the tape feeder 10 that is estimated to have a fault, and thus the identification is performed in accordance with a priority.
