Abstract

A component mounting machine performs a mounting operation of mounting an electronic component to a board. The component mounting machine includes: multiple related operation devices each including an electrically-operated section configured to perform a related operation that is an operation related to the mounting operation, and an output section configured to output an operation signal representing a state of the electrically-operated section that is operating; and circuitry configured to limit the quantity of the related operation devices for which the electrically-operated section is in an operating state to a specified quantity or fewer based on whether there is presence of the operation signal of the multiple related operation devices.

First claim

The invention claimed is:

1. A component mounting machine configured to perform a mounting operation of mounting an electronic component to a board, the component mounting machine comprising:
multiple related operation devices each including an electrically-operated section configured to perform a related operation that is an operation related to the mounting operation, and an output section configured to output an operation signal representing a state of the electrically-operated section that is operating; and
circuitry configured to
count a signal quantity of the operation signals being output from all of the related operation devices,
compare the signal quantity of the operating signals to a predetermined value,
when the signal quantity of the operating signals is greater than or equal to the predetermined value, output an interlock signal to the related operation devices in a stopped state to prohibit the related operations in the stopped state from transition to an operating state, and
when the signal quantity of the operating signals is less than the predetermined value and the interlock signal is being output to the related operation devices in the stopped state, determine a release target among the related operation devices in the stopped state to which the interlock signal is being output, and cancel the interlock signal to the release target to allow the release target to transition to the operating state, wherein the related operation devices comprise
a feeder device configured to perform a supply operation of the electronic components using carder tape,
a pallet device configured to perform a supply operation of the electronic components using a pallet on which a tray or a dicing sheet is loaded,
a dip device configured to perform a supply operation of adhesive material or solder paste, and
a defective component collection device configured to perform a collection operation of collecting the electronic components that have been determined as defective.

2. The component mounting machine according to claim 1 , wherein the circuitry is further configured to
acquire information of an order in which the multiple related operation devices will operate from a mounting control section configured to control the mounting operation, and
determine the release target for the interlock signal from the related operation devices that are in the stopped state, in accordance with the acquired order.

3. The component mounting machine according to claim 1 , wherein the circuitry is further configured to
memorize a history of the operating states of the multiple related operation devices, and
determine the release target for the interlock signal from the related operation devices that are in the stopped state, in an order based on which is newest of the history of the operating states from among the related operation devices that are in the stopped state.

4. The component mounting machine according to claim 1 , wherein the related operation device includes a reservation output section configured to output a reservation signal for reserving transition to the operating state in a case in which an operation request for transitioning to the operating state occurs while the interlock signal is being received in the stopped state, and
wherein the circuitry is further configured to determine the release target for the interlock signal from the related operation devices that are in the stopped state in accordance with an order in which the reservation signals are received.

5. The component mounting machine according to claim 1 , wherein the circuitry is further configured to
hold information of an order associated in advance with the multiple related operation devices, and
determine, as a current release target for the interlock signal, the related operation device that is in the stopped state that is subsequent in the order to the related operation device for which the interlock signal was just previously canceled.

6. The component mounting machine according to claim 1 , wherein the circuitry is further configured to determine the release target for the interlock signal at random from the related operation devices that are in the stopped state.
