Abstract

A production system includes a first production line and a second production line arranged in parallel with each other, and a first feeder exchange device and a second feeder exchange device respectively provided in each production line at an interval with which the first feeder exchange device and the second feeder exchange device can pass by each other. When the production is stopped, the first feeder exchange device and the second feeder exchange device stop at intervals of a predetermined distance or more in a board conveyance direction.

First claim

The invention claimed is:

1 . A production system comprising:
a first production line including multiple component mounting machines that are arranged in a board conveyance direction, are provided with attachable and detachable sections to and from which feeders are attached and detached, and mount components supplied from the feeders mounted on the attachable and detachable sections on a board; a second production line including multiple component mounting machines that are arranged in parallel with the first production line, are provided with attachable and detachable sections so as to face the attachable and detachable sections of the first production line, and mount components supplied from feeders mounted on the attachable and detachable sections on the board; a first feeder exchange device configured to move in an alignment direction of each component mounting machine of the first production line and exchange a feeder by attaching and detaching the feeder to and from the attachable and detachable section of each component mounting machine of the first production line; and a second feeder exchange device configured to move in an alignment direction of each component mounting machine of the second production line at an interval that allows the second feeder exchange device to pass by the first feeder exchange device and exchange a feeder by attaching and detaching the feeder to and from the attachable and detachable section of each component mounting machine of the second production line, wherein when a production is stopped, the first feeder exchange device and the second feeder exchange device are stopped at an interval of a predetermined distance or more from each other in the board conveyance direction.

2 . The production system according to claim 1 ,
wherein when the production is stopped by completing a scheduled number of productions, the first feeder exchange device and the second feeder exchange device respectively move to predetermined stop positions and stop, and the stop position of the first feeder exchange device and the stop position of the second feeder exchange device are determined at positions separated from each other by the predetermined distance or more in the board conveyance direction.

3 . The production system according to claim 1 ,
wherein when the production is stopped by an occurrence of a predetermined abnormality, the first feeder exchange device and the second feeder exchange device stop when the first feeder exchange device and the second feeder exchange device are separated from each other by the predetermined distance or more in the board conveyance direction, and move to positions separated from each other by the predetermined distance or more and then stop when the first feeder exchange device and the second feeder exchange device are not separated from each other by the predetermined distance or more in the board conveyance direction.

4 . The production system according to claim 3 ,
wherein when the production is stopped by an abnormality occurring in any of the component mounting machines constituting the first production line and the second production line, the first feeder exchange device and the second feeder exchange device are separated from each other by the predetermined distance or more in the board conveyance direction, and stop at positions avoiding a vicinity of the component mounting machine in which the abnormality has occurred.

5 . The production system according to claim 1 ,
wherein when a stop instruction is issued by a predetermined operation, the first feeder exchange device and the second feeder exchange device stop at the interval of the predetermined distance or more from each other in the board conveyance direction.

6 . The production system according to claim 1 , further comprising:
an automatic conveyance device configured to load and unload feeders into and from the first production line and the second production line in a predetermined traveling route in a predetermined time zone or schedule, wherein the first feeder exchange device and the second feeder exchange device stop at positions avoiding the traveling route at a timing when the automatic conveyance device loads and unloads the feeders into and from the first production line and the second production line.

7 . A production system comprising:
a first production line including multiple component mounting machines that are arranged in a board conveyance direction, are provided with attachable and detachable sections to and from which feeders are attached and detached, and mount components supplied from the feeders mounted on the attachable and detachable sections on a board; a second production line including multiple component mounting machines that are arranged in parallel with the first production line, are provided with attachable and detachable sections so as to face the attachable and detachable sections of the first production line, and mount components supplied from feeders mounted on the attachable and detachable sections on the board; a first feeder exchange device configured to move in an alignment direction of each component mounting machine of the first production line and exchange a feeder by attaching and detaching the feeder to and from the attachable and detachable section of each component mounting machine of the first production line; a second feeder exchange device configured to move in an alignment direction of each component mounting machine of the second production line at an interval that allows the second feeder exchange device to pass by the first feeder exchange device and exchange a feeder by attaching and detaching the feeder to and from the attachable and detachable section of each component mounting machine of the second production line; and an intrusion detecting sensor configured to detect an intrusion of a person into a region which is surrounded by the first production line and the second production line, wherein when the intrusion of the person is detected by the intrusion detecting sensor, the first feeder exchange device and the second feeder exchange device stop at an interval of a predetermined distance or more from each other in the board conveyance direction.
