An electric power supply device for supplying electric power from a supply side device to a receiver side device including a mechanism section that operates intermittently with a drive voltage and a receiver side control section that controls an operation of the mechanism section with a control voltage that is lower than the drive voltage, the electric power supply device including: a regulator section, which is provided on the receiver side device, that converts a received voltage received via an electric power supply into the control voltage; a supply voltage adjusting section, which is provided on the supply side device, that adjustably supplies the received voltage; and a supply side control section, which is provided on the supply side device, that controls the received voltage by controlling the supply voltage adjusting section.

A component mounting related system is provided with a first component mounting related apparatus, a second component mounting related apparatus, an electric power source provided in the first component mounting related apparatus, a first power transmission line provided in the first component mounting related apparatus, a power transmission connector, and a second power transmission line. The electric power source supplies an electric power for actuating the first component mounting related apparatus. The first power transmission line transmits the electric power in the first component mounting related apparatus. The power transmission connector transmits the electric power transmitted by the first power transmission line to the second component mounting related apparatus. The second power transmission line transmit, in the second component mounting related apparatus, the electric power supplied from the first component mounting related apparatus through the power transmission connector.

A soldering and de-soldering station and systems including enhanced features for the soldering heating tools and load detection functionality.

There is provided a power supply device for a work unit that supplies power to multiple work units constituting a work device as power supply targets, the device including: a first power supply line through which power supply is stopped when an emergency stop condition is satisfied and a second power supply line through which power supply is not stopped even when the emergency stop condition is satisfied, in which the first power supply line and the second power supply line can be used individually according to a difference in a safety structure of each work unit. According to this, when the emergency stop condition is satisfied, it is possible to reduce the restoration time required when the emergency stop is eliminated while guaranteeing the safety of the entire work device configured by the multiple work units.

A power supply shutoff device includes a movable section, a driving section, a power supply device, a power distribution section, an electric power supply circuit, and a supply control section. The movable section is configured to travel on a traveling path provided along a board production line in which multiple board work machines, which perform a predetermined board work on a board, are installed side by side. The driving section is provided in the movable section and configured to cause the movable section to travel by using supply electric power supplied from the board work machine with non-contact power feeding. The supply control section is configured to stop a supply of the electric power to the electric power supply circuit when drive electric power for driving the board work machine is shut off in at least one board work machine among the multiple board work machines.

In a component-mounted-board production line in which an automatic exchanging device moves along a row of multiple component mounters, each component mounter is provided with a power supplying section that supplies power wirelessly. The automatic exchanging device is provided with a power receiving section that receives electric power supplied wirelessly from the power supplying section of the component mounter that the automatic exchanging device is facing, a monitoring section that monitors whether a person or object has entered a monitoring area around the automatic exchanging device, and a safety circuit section that turns off the power supply to a motor that is the driving source of the automatic exchanging device but continues supplying power to the monitoring section and the like when the monitoring section detects that a person or object has entered the monitoring area.

In a board work system, the CPU of a board work device transmits error related information which relates to an error in a case where the error has occurred in the own device. Then, the CPU receives the error related information which relates to the error of the other board work device, and stores the received error related information in the HDD. Then, the display operation section is controlled such that information (other device error notification screen) based on the stored error related information is notified to the operator in a case where the power source of the board work device (other board work device), in which the error has occurred, is detected to be switched off.

A control device and method for supplying power to feeders inserted from multiple slots each of which includes an indicator lamp and into which the feeders are inserted, the method including a feeder insertion position indication step of turning on an indicator lamp of a slot to which the power is supplied, a feeder insertion step of inserting the feeder into the slot to which the power is supplied and of which the indicator lamp is turned on in the feeder insertion position indication step, and a power supply check step of, in a case where the feeder inserted in the feeder insertion step is a normal feeder, turning off the indicator lamp of the slot to which the power is supplied, the indicator lamp being turned on by supplying the power to the inserted feeder.

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.
