Feeder Reel Holder Dynamics for Compact Tape Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional feeders require a wide interval between holder main bodies to accommodate tape fed from a reel, limiting the number of feeders that can be set on a feeder setting base due to the need for the tape to pass between upper and lower holder main bodies.
Innovation Solution
A feeder design incorporating a reel holder with a slider and tape pressing member that allows the tape to be pressed toward the feeder main body from the upper side, enabling a smaller interval between holder main bodies and allowing more feeders to be set on the base without risk of reel floating or tape entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interval between holder main bodies is increased to accommodate tape feeding, then the tape can pass between holder main bodies without entanglement, but the number of feeders that can be set on the feeder setting base is reduced
Solution Approach 1:
The patent introduces a vertical dimension by allowing the holder main body to move between upper and lower positions. The tape pressing member presses the tape from the upper side when the holder is in the upper position, and the tape passes through the holder main body when it is in the lower position. This vertical movement resolves the horizontal space conflict and enables closer spacing of feeders.
Solution Approach 2:
The holder main body is designed to be movable between upper and lower positions rather than fixed. This dynamic positioning allows the system to adapt the tape passage path based on the holder's position, enabling the tape to pass through the holder main body when needed and preventing entanglement when the holder is in the upper position.
2Device complexity
If the holder main body is fixed in position, then the structure is simple, but the tape may pass between holder main bodies requiring large intervals
Solution Approach 1:
The holder main body is designed to be movable between upper and lower positions rather than fixed. This dynamic positioning allows the system to adapt the tape passage path based on the holder's position, enabling the tape to pass through the holder main body when needed and preventing entanglement when the holder is in the upper position.
Solution Approach 2:
The patent introduces a vertical dimension by allowing the holder main body to move between upper and lower positions. The tape pressing member presses the tape from the upper side when the holder is in the upper position, and the tape passes through the holder main body when it is in the lower position. This vertical movement resolves the horizontal space conflict and enables closer spacing of feeders.
3Device complexity
If no tape pressing member is provided, then the structure is simple, but the reel may float during tape feeding
Solution Approach 1:
The tape pressing member is integrated with the slider and holder main body assembly, allowing the structure to press the tape itself during the feeding process. This self-service mechanism prevents reel floating without requiring separate external pressing devices.
Solution Approach 2:
The tape pressing member acts as an intermediary element between the tape and the reel. It applies downward pressure on the tape to prevent the reel from floating upward during the tape feeding process, stabilizing the reel position without direct mechanical contact with the reel itself.

AI summary
A feeder of the present disclosure includes a feeder main body configured to feed a tape in which a component is accommodated to a predetermined position, and a reel holder attached to an upstream side of the feeder main body in a feeding direction of the tape and configured to hold a reel on which the tape is wound, in which the reel holder includes a holder main body configured to hold the reel, a slider that is integrated with the holder main body, and a tape pressing member that is integrated with the slider and is capable of pressing the tape fed from the reel toward the feeder main body from an upper side.
