Abstract

It is an object of the present invention to provide a component management system or the like that can accurately predict component exhaustion in a component mounting device that performs work at a line. Specifying section updates the time table based on the arrival time point or the unloading time point in each of component mounting devices. Arrival predicting section predicts the arrival time point in each component mounting device based on the time table and updates a prediction table. Since component-exhaustion predicting section acquires the arrival time point of a circuit board for which a component will be exhausted from the prediction table and calculates a component exhaustion time point, it is possible to predict the component exhaustion time point with high accuracy. An operator can perform a replenishment work based on the component exhaustion time point.

Claims

1-10. -10. (canceled)

11. A component management system for managing component mounting on a board in a component mounting line in which multiple work devices, including at least one component mounting device, are arranged in a line, the component management system comprising:

a specifying section configured to specify a location of each board at the component mounting line;

an arrival predicting section configured to predict an arrival time point of each board at a target device based on the location specified by the specifying section, the target device being defined as one of the component mounting devices;

a component-exhaustion predicting section configured to calculate the number of boards to be mountable based on the number of remaining components and the number of components to be mounted per board in the target device, and configured to predict a component exhaustion time point, at which the component is exhausted in the target device, based on the number of boards and the arrival time point, and

a notification section configured to report the component exhaustion time point or a component supply time point based on the component exhaustion time point.

12. The component management system according to claim 11, further comprising:

a replenishment time point calculating section configured to calculate a component replenishment time point, which is a start time limit of component replenishment, based on the component exhaustion time point and a replenishment time period required for the component replenishment.

13. The component management system according to claim 11, wherein

the specifying section specifies the location by acquiring the arrival time point or an unloading time point of the board at each of the working devices.

14. The component management system according to claim 13, wherein

the arrival predicting section predicts the arrival time point based on the arrival time point or the unloading time point, a work time period of each of upstream devices located upstream of the target device, and a conveyance time period required for the board to be conveyed from the upstream device to the target device.

15. The component management system according to claim 13, wherein

when mounting work of the upstream device is interrupted, the arrival predicting section predicts an arrival time point of a board after a board already unloaded from the interrupted device based on a current time point, the work time of the interrupted device and the work time of each of the upstream devices on the component mounting line from the interrupted device to the target device, and the conveyance time from the interrupted device to the target device.

16. The component management system according to claim 11,

wherein the notification section reports that the component exhaustion time point may be delayed when mounting of the upstream device is interrupted.

17. The component management system according to claim 16, wherein

the notification section reports an elapsed time period from the interruption when mounting of the upstream device is interrupted.

18. The component management system according to claim 11, wherein

when the component mounting device in the component mounting line includes multiple component mounting devices, the notification section reports the component exhaustion time point or the component supply time point in an order of earlier time point based on the arrival time point predicted by the arrival predicting section for each of the component mounting devices.

19. The component mounting device which is managed by the component management system according to claim 11, comprising:

a device notification section configured to report the component exhaustion time point or the component supply time point.

20. A component management method for managing component mounting on a board in a component mounting line in which multiple work devices, including at least one component mounting device, are arranged in a line, the method comprising:

a specifying step of specifying a location of each board at the component mounting line;

an arrival predicting step of predicting an arrival time point of each board in a target device, which is one of the component mounting devices, based on the location specified by the specifying step;

a component-exhaustion predicting step of calculating the number of boards that can be mounted based on the number of components remaining and the number of components to be mounted per board in the target device, and predicting a component exhaustion time point, at which the component is exhausted in the target device, based on the number of boards and the arrival time point; and

a notifying step of reporting the component exhaustion time point or a component supply time point based on the component exhaustion time point.
