Tape Ejection Guide Structure for Component Supply Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting machines, the ejection of component storing tapes is not always certain due to changes in posture within the ejection guide, especially when the preceding tape is pushed out by the succeeding tape, leading to potential misalignment and failure in ejection.
Innovation Solution
A tape ejection guide structure is implemented, featuring a guide body that directs the upper or lower surface of the component storing tape and a pair of restraining portions to prevent displacement in the tape width direction, ensuring the tape is ejected correctly and avoiding posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the preceding component storing tape is pushed out by the succeeding component storing tape in the ejection guide, then the preceding tape can be ejected, but the posture of the preceding tape may change due to inclination, causing uncertain ejection
Solution Approach 1:
The ejection guide is divided into multiple functional sections: a guide body for directing the upper or lower surface of the tape, and a pair of restraining portions connected to both end portions of the guide body. This segmentation allows the guide body to handle the ejection path while the restraining portions specifically control tape displacement in the width direction, ensuring stable posture during ejection.
Solution Approach 2:
The restraining portions act as intermediary elements between the guide body and the tape edges. These portions restrain the displacement of the tape in the width direction by contacting the side edges of the tape, preventing posture changes caused by inclination during the ejection process when the preceding tape is pushed by the succeeding tape.
2Device complexity
If the component storing tape is guided only by the guide body without restraining portions, then the structure is simpler, but the tape may displace in the width direction causing ejection failure
Solution Approach 1:
The guide structure is segmented into a guide body and separate restraining portions. This segmentation adds functionality without significantly increasing overall complexity, as the restraining portions are integrated with the guide body's end portions. The segmentation allows each component to perform its specific function: guiding the tape surface and restraining width-wise displacement.
Solution Approach 2:
The restraining portions are positioned at specific locations (connected to both end portions of the guide body) to provide localized control over tape displacement. This local quality approach ensures that tape posture is maintained at critical points where displacement would cause ejection failure, without requiring complex control mechanisms throughout the entire guide structure.

AI summary
A tape ejection guide structure (8) is a structure which guides ejection of a component storing tape (100) ejected from a tape ejection port (23) of a component supply unit (1A), and includes a guide body (81), and a pair of restraining portions (83). The guide body (81) guides an upper surface portion (100A) of the component storing tape (100) which is ejected from the tape ejection port (23) in a tape ejection direction (H2). A pair of restraining portions (83) is connected to both end portions of the guide body (81) in a tape width direction (H3) respectively, and restrains the displacement in the tape width direction (H3) of the component storing tape (100) which is ejected in a state where the upper surface (100A) is guided by the guide body (81).
