Feeder Reel Exchange with Tape Rewinding and Cutoff Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automation of reel exchange operations in feeders is hindered by the need to detach and rewind tapes efficiently to maintain production efficiency, particularly when reels are reused, as existing methods do not adequately address the rewinding and cutting of tapes to prevent component loss.
Innovation Solution
A reel installation and removal device with a feeder set unit, reel transfer unit, holding section, and cutting section, controlled by a control device, facilitates rapid rewinding and cutting of tapes to ensure seamless reel detachment and attachment, minimizing component loss and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the reel is automatically detached from the feeder, then the automation of reel exchange is improved, but the tape may not be properly rewound and cut, causing component loss
Solution Approach 1:
The system performs preliminary actions by driving the feeding section to rewind the tape onto the reel and positioning the cutting section to cut the tape at the appropriate location before completing the reel detachment. This ensures the tape is properly processed before the reel is fully removed from the feeder.
2Loss of substance
If the tape is rewound and cut to a portion where component has been supplied, then component loss is prevented, but the detachment process becomes more complex
Solution Approach 1:
The feeding section serves a dual function: it not only feeds the tape during normal operation but also rewinds the tape onto the reel during detachment. This self-service capability eliminates the need for a separate rewinding mechanism, preventing component loss while avoiding additional device complexity.
3Ease of operation
If the feeder is set in the feeder set unit for detachment, then the detachment operation is simplified, but the feeding section must be driven which requires additional control
Solution Approach 1:
The feeder set unit is designed to accommodate the feeder in a configuration that enables both normal feeding operations and detachment operations. The feeding section is controlled to perform multiple functions: feeding tape during operation and rewinding tape during detachment, reducing the need for separate mechanisms and simplifying the overall detachment operation.

AI summary
A reel installation and removal device that installs and removes a reel on which a tape containing components is wound, the device including a control device configured to execute a detachment control of driving a holding section and a cutting section so that the tape is held and cut in a portion to which the component has been supplied after driving a feeding section and a rotation section so that the tape is rewound and wound around the reel, and controlling the feeder set unit and the reel transfer unit so as to detach the reel from the feeder in a state where the feeder to which the reel is attached is set in the feeder set unit.
