Abstract

A component mounting system including multiple component mounting devices to collect components from feeders set at multiple feeder holding sections and mount the components on a board, the multiple feeder holding sections being provided on each of the multiple component mounting devices to removably hold the feeders; and a feeder exchanging device to move along a line along which the multiple component mounting devices are arranged and exchange feeders with respect to each of the component mounting devices. The component mounting system acquires a type and arrangement of each of the feeders set on the multiple component mounting devices, determines whether each of the feeders is set at a predetermined appropriate position, and upon determining that there is a feeder that is not set at the appropriate position, uses the feeder exchanging device to reset the feeder that is not set at the appropriate position.

First claim

The invention claimed is:

1. A component mounting system comprising:
multiple component mounting devices configured to collect components from feeders set at multiple feeder holding sections and mount the components on a board, the multiple feeder holding sections being provided on each of the multiple component mounting devices and configured to removably hold the feeders;
a feeder exchanging robot configured to move along a line along which the multiple component mounting devices are arranged and exchange feeders with respect to each of the component mounting devices; and
a management device including circuitry configured to receive information from the multiple component mounting devices and send setup change instructions to the feeder exchanging robot, wherein
the management device is configured to
determine target feeders that are targets for operation among all the feeders set on each of the multiple component mounting devices,
acquire a current slot number in which the target feeders are set,
acquire a correct slot number of the target feeders from job information stored in memory of the management device,
determine whether each of the feeders is set at a predetermined appropriate position when the current slot number matches the appropriate slot number, and
upon determining that there is a feeder that is not set at the appropriate position, set the current slot number of the feeder that is not set at the appropriate position to an exchange source slot number, set the appropriate slot number to an exchange destination slot number, and control the feeder exchanging robot to reset the feeder that is not set at the appropriate position to the appropriate position for that feeder based on the exchange source slot number and the exchange destination slot number.

2. The component mounting system according to claim 1 , wherein
when the management device determines that there is a feeder that is not set at the appropriate position, the management device is configured to control the feeder exchange robot to reset the feeder that is not set at the appropriate position to the appropriate position for that feeder while mounting operation is not occurring at the component mounting device for that feeder.

3. The component mounting device according to claim 1 , wherein
when the management device determines that there is a feeder that is not set at the appropriate position, the management device is configured to control the feeder exchange robot to reset the feeder that is not set at the appropriate position to the appropriate position for that feeder while a board is being loaded into the component mounting device for that feeder or while a board is being unloaded from the component mounting device for that feeder.

4. The component mounting system according to claim 1 , wherein
when the management device determines that, with respect to one of the component mounting devices, there is a feeder that is set at the appropriate position and a feeder that is not set at the appropriate position, the management device is configured to control the feeder exchanging robot to reset the feeder that is not set at the appropriate position to the appropriate position for that feeder while mounting operation is being performed by collecting components from the feeder that is set at the appropriate position.

5. The component mom ting system according to claim 4 , wherein
the management device is further configured to adjust a mounting order such that mounting operation is performed by collecting components with priority from feeders set at the appropriate position.

6. The component mounting system according to claim 1 , wherein
the feeder exchanging robot includes a feeder transfer mechanism including a clamp section which clamps the feeder and a slider which moves the clamp section along a guide rail.
