Transfer Apparatus Peeling Stability via Tangent Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer apparatuses experience instability in the posture of recording media after peeling off transfer films, leading to transfer failures due to the intermediate transfer film pulling the card front end, causing uneven peeling and image quality degradation.
Innovation Solution
A transfer apparatus with a support member that stabilizes the recording medium post-peeling, featuring a peeling member and support member held by a common bracket, ensuring the peeling member contacts the recording medium at a specific tangent line relative to the transfer member, and the support member at another tangent line, maintaining a stable peeling position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peeling member and transport rollers are spaced apart, then the peeling action can be performed, but the card posture becomes unstable after peeling
Solution Approach 1:
A support member is introduced as an intermediary element between the peeling member and the transport rollers. This support member provides temporary support to the card after peeling, preventing posture instability without interfering with the peeling action itself. The support member acts as a mediator that bridges the gap between the peeling operation and the transport operation.
Solution Approach 2:
The support member is positioned specifically at the location where the card requires support after peeling, rather than providing uniform support throughout the entire transport path. This localized support approach addresses the specific problem of posture instability at the critical post-peeling moment while maintaining the effectiveness of the peeling action.
2Reliability
If the intermediate transfer film pulls the card front end during peeling, then peeling can occur, but the peeling position becomes unstable and transfer failures occur
Solution Approach 1:
The support member is positioned in advance at the location where the card will be after peeling. By having this support ready beforehand, the system prevents the card from adopting unstable postures that would lead to incorrect peeling positions. This preliminary preparation counteracts the destabilizing effect of the transfer film pulling on the card.
3Reliability
If the card rear end is raised upward during peeling, then peeling can proceed, but premature peeling occurs before the card reaches the peeling member
Solution Approach 1:
The support member serves as an intermediary that stabilizes the card posture during the peeling process. By providing support at the appropriate location, it prevents the card rear end from rising upward and causing premature peeling, while still allowing the peeling process to occur at the correct position.

Function Achieved in This Case
This configuration stabilizes the recording medium's posture post-peeling, prevents premature peeling of the transfer film, and ensures a stable peeling position, reducing transfer failures and maintaining image quality.

AI summary
A transfer apparatus for heating a recording medium and a transfer film with a transfer member and a transfer platen transferring an image includes a transfer film transport member, a recording medium transport member, a peeling member peeling off the transfer film, a support member supporting the transfer surface of the recording medium, and a bracket. A recording medium contact point of the peeling member is set in the same position as a first tangent passing through a recording medium contact point of the transfer member and a contact of the recording medium of a transport member and a recording medium contact point of the support member is set in the same position as a second tangent passing through the recording medium contact point of the transfer member and the recording medium contact point of the peeling member or on the transfer platen side relative to the second tangent.
