Feeder Power Control for Static Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting apparatuses face reduced power saving effects and increased costs for countermeasures against static electricity due to continuous power supply to feeder control sections during standby periods, leading to heating and static electricity issues.
Innovation Solution
The power supply to feeders is turned OFF during standby periods exceeding operation preparation time and turned ON earlier than the standby period's end, reducing heating and static electricity, while maintaining power for feeders supplying small components to prevent position deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power is continuously supplied to the control section of the feeder during standby period, then the feeder can immediately resume operation after standby, but power consumption increases and the control section is heated causing static electricity
Solution Approach 1:
The power supply to the feeder control section is switched between ON and OFF states periodically based on the standby period duration. The control section is turned OFF during standby to save power and turned ON again before the standby period ends to ensure immediate resumption of operation, creating a periodic power supply pattern that balances energy saving with operational readiness.
2Productivity
If power is continuously supplied to the control section of the feeder during standby period, then the feeder can immediately resume operation, but the control section is heated and air around the feeder becomes dry causing static electricity
Solution Approach 1:
The power supply to the feeder control section is switched between ON and OFF states periodically based on the standby period duration. The control section is turned OFF during standby to save power and turned ON again before the standby period ends to ensure immediate resumption of operation, creating a periodic power supply pattern that balances energy saving with operational readiness.
3Loss of energy
If power is turned OFF to the feeder during standby period, then power saving effects are increased and heating is eliminated, but operation preparation time is required after power is turned ON again
Solution Approach 1:
The control section is turned ON again before the standby period officially ends, specifically at a timing that allows the operation preparation time to elapse before the feeder is needed. This preliminary action ensures that the feeder is fully ready for operation before the standby period concludes, eliminating any delay in resuming component supply.
4Loss of energy
If power is turned OFF to the feeder during standby period, then power saving effects are increased, but costs for countermeasure against static electricity increase
Solution Approach 1:
The power supply to the feeder control section is switched between ON and OFF states periodically based on the standby period duration. The control section is turned OFF during standby to save power and turned ON again before the standby period ends to ensure immediate resumption of operation, creating a periodic power supply pattern that balances energy saving with operational readiness.

AI summary
A component mounting apparatus 11 is provided with a plurality of power supply switches 31 that turn ON/OFF a power supply to each feeder 14 for each feeder 14. A control section 30 of the component mounting apparatus 11 determines a feeder standby period in which a component supply operation of each feeder 14 is stopped to be in standby during execution of a production job based on the production job and for the feeder 14 in which the feeder standby period exceeds an operation preparation time after the power supply is turned ON again (or slightly longer time than that), the power supply switch 31 is turned OFF and the power supply to the feeder 14 is turned OFF when starting of the feeder standby period, and the power supply switch 31 is turned ON and the power supply is turned ON again to the feeder 14 at timing earlier than when finishing the feeder standby period by the operation preparation time after the power supply is turned ON again (or slightly longer time than that).
