Abstract

A system including: an automatic exchanging device configured to move along the multiple component mounters arranged in a line and automatically exchange automatically exchangeable units of the component mounters; an operation monitoring device configured to monitor an operation state of the automatically exchangeable units of the component mounters and monitor whether it is necessary to exchange the automatically exchangeable units due to maintenance or a breakdown; and a management device configured to, when the operation monitoring device determines that exchange of one of the automatically exchangeable units of the component mounters is necessary due to maintenance or a breakdown, move the automatic exchanging device to the component mounter in question and cause the automatic exchanging device to perform automatic exchange of the automatically exchangeable unit of the component mounter with an exchange-use unit.

First claim

1 .- 9 . (canceled)

10 . A system for managing a component mounting line configured from multiple component mounters arranged in a line along a conveyance path of a circuit board, the component mounters producing a component-mounted board by mounting component on the circuit board, the system comprising:
an automatic exchanging device configured to move along the multiple component mounters arranged in a line and automatically exchange automatically exchangeable units of the component mounters; an operation monitoring device configured to monitor an operation state of the automatically exchangeable units of the component mounters and monitor whether it is necessary to exchange the automatically exchangeable units due to maintenance or a breakdown; and a management device configured to, when the operation monitoring device determines that exchange of one of the automatically exchangeable units of the component mounters is necessary due to maintenance or a breakdown, move the automatic exchanging device to the component mounter in question and cause the automatic exchanging device to perform automatic exchange of the automatically exchangeable unit of the component mounter with an exchange-use unit.

11 . The system for managing the component mounting line according to claim 10 , wherein
the automatically exchangeable unit is any of a feeder configured to supply components, a suction nozzle configured to pick up the component, a chuck configured to grasp the component, or a mounting head configured to hold the suction nozzle or the chuck.

12 . The system for managing the component mounting line according to claim 10 , wherein
the component mounting line is provided with a storage compartment configured to store exchange-use units to be exchanged with the automatically exchangeable units of the multiple component mounters, and the automatic exchanging device is configured to, in accordance with an instruction from the management device, receive the exchange-use unit from the storage compartment, move to the component mounter at which automatic exchange is to be performed, automatically exchange the automatically exchangeable unit of the component mounter with the exchange-use unit, and load the collected automatically exchangeable unit in the storage compartment.

13 . The system for managing component mounting line according to claim 12 , further comprising
a unit transport device configured to move to and from a work location at which an operator performs work and the storage compartment, wherein at the work location, an operator loads the exchange-use unit on the unit transport device, the unit transport device moves to the storage compartment, loads the exchange-use unit into the storage compartment, loads the exchanged automatically exchangeable unit collected in the storage compartment on the unit transport device, and returns to the work location.

14 . The system for managing the component mounting line according to claim 13 , wherein
the work location and the unit transport device are shared between multiple component mounting lines.

15 . The system for managing the component mounting line according to claim 10 , wherein
the operation monitoring device is provided on each the component mounters, and the operation monitoring device is configured to monitor at least one of a tape feeding time of a feeder that is the automatically exchangeable unit of the component mounter, a flow amount or a nozzle length of a suction nozzle that is the automatically exchangeable unit of the component mounter, or an axis movement time or valve operation time of a mounting head that is the automatically exchangeable unit of the component mounter, and to monitor whether it is necessary to exchange the automatically exchangeable units due to maintenance or a breakdown based on whether a specified value of the at least one of the tape feeding time, the flow amount, the nozzle length, the axis movement time, or the valve operation time exceeds a specified threshold.

16 . The system for managing the component mounting line according to claim 10 , wherein
the operation monitoring device is provided with a determination criteria changing section configured to allow an operator to change a determination criteria used to determine whether it is necessary to exchange the automatically exchangeable unit due to maintenance or a breakdown.

17 . The system for managing the component mounting line according to claim 10 , wherein
the operation monitoring device is configured to send, in advance, to the management device, information related to the automatically exchangeable unit for a case in which it was possible to predict a timing at which exchange of the automatically exchangeable unit of the component mounter is required due to maintenance or a breakdown, and the management device is configured to, when the information related to the exchange of the automatically exchangeable unit of the component mounter is received in advance from the operation monitoring device, as preparation for exchange of the automatically exchangeable unit, move the automatic exchanging device to or near to the component mounter.

18 . The system for managing the component mounting line according to claim 10 , wherein
each component mounter is provided with a stock section configured to temporarily accommodate the exchange-use unit and the collected automatically exchangeable unit that has been exchanged, and the management device is configured to, as preparation for exchange of the automatically exchangeable unit of each component mounter, use a period in which the automatic exchanging device is not going to perform automatic exchange of the automatically exchangeable unit to move the automatic exchanging device to each of the component mounters, accommodate the exchange-use unit in the stock section, and collect the automatically exchangeable unit that has been exchanged from the stock section.
