Feeder Jam Suppression Control for Component Mounters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing feeders, when removed from a feeder table before rewinding, empty tapes can become caught between the feeder and the table, leading to jamming issues upon re-mounting, disrupting component supply.
Innovation Solution
Implementing a jam suppression control mechanism that rewinds the tape a predetermined amount and feeds it out before rewinding, along with a cutting device to minimize tape protrusion and prevent catching, ensuring proper component supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeder is removed from the feeder table before the empty tape is rewound, then the operator can exchange the feeder, but the empty tape becomes caught between the feeder and the feeder table causing jamming
Solution Approach 1:
The system performs preliminary actions by detecting feeder removal and automatically rewinding the empty tape before the feeder is fully detached. The control unit monitors feeder status and triggers the feed motor to rewind the tape in advance, preventing the tape from protruding and getting caught during the exchange operation.
Solution Approach 2:
The control unit implements feedback control by continuously monitoring the feeder's mounted state through detection units. When the feeder is detected as removed, the system automatically activates the rewind function. When the feeder is detected as remounted, the system automatically performs the cue-up operation to restore proper tape feeding, creating a closed-loop control system that prevents jamming.
2Reliability
If the empty tape is completely rewound to prevent protrusion, then tape catching is prevented, but the tape supply position is disrupted requiring additional cue-up operation
Solution Approach 1:
The system performs a preliminary cue-up operation after feeder remounting to restore the tape supply position before actual component feeding begins. The control unit automatically feeds out the tape a predetermined distance to ensure the tape is properly positioned and ready for supply, eliminating the need for manual intervention and ensuring smooth operation.
Solution Approach 2:
The system maintains continuous operational readiness by automatically performing the cue-up operation immediately after feeder remounting. This ensures the tape is continuously prepared and positioned correctly, allowing component supply to resume without interruption or loss of productivity.

AI summary
A feeder is configured to be detachably attached to a mounter body for supplying components to the mounter body. This feeder includes a motor configured to feed out a tape accommodating multiple components, and when the feeder is removed from and re-mounted on a feeder table of the mounter body, the motor is caused to be driven to rewind the tape a predetermined amount, and the motor is caused to be driven to feed out the tape to a position before the tape is rewound.
