Tape Winding Apparatus with Dynamic Push Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tape winding systems face challenges in maintaining precise and aligned winding profiles at high speeds due to variations in tensile force, which adversely affect the pressing force of the push roller, leading to potential tape edge misalignment and damage.
Innovation Solution
A tape winding apparatus with a rotating device, a push roller, and a feeding direction control guide that ensures the tape-feeding direction conforms to the tangential direction of the tape roll, using a movement device to stabilize the push roller and prevent shifting, thereby maintaining alignment and precision even at high wind-up speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wind-up speed is increased to improve productivity, then the tape can be wound faster, but the variation in tensile force adversely affects the pressing force of the push roller, making it difficult to maintain precise and aligned winding profile
Solution Approach 1:
The push roller is made movable along the tape width direction through a swing arm mechanism, allowing it to dynamically adjust its position to compensate for tensile force variations and maintain optimal pressing contact with the tape roll during high-speed winding operations
Solution Approach 2:
A position control roller monitors the tape feed direction and provides feedback control to the swing arm mechanism, ensuring the push roller maintains correct positioning and pressing force despite variations in tensile force during high-speed operation
2Manufacturing precision
If the push roller is pressed against the tape roll to remove air and improve winding profile alignment, then the preciseness and alignment are improved, but the tensile force urges the push roller away from the tape roll, reducing pressing force effectiveness
Solution Approach 1:
The push roller is supported on a swing arm that allows it to move dynamically along the tape width direction, maintaining stable contact and pressing force against the tape roll despite tensile force variations that would otherwise push the roller away
Solution Approach 2:
The swing arm mechanism provides a counterbalancing support structure that opposes the tensile force tendency to push the push roller away from the tape roll, maintaining consistent pressing force for air removal and alignment

AI summary
A tape winding apparatus includes: a rotating device configured to rotate a wind-up core for winding a tape into a roll which defines a tape roll; a push roller configured to be pressed against the tape roll, the push roller contacting with and rolling on an outer periphery of the tape roll at a tape feeding position where the tape is fed onto the tape roll; a feeding direction control guide arranged upstream from the push roller as viewed in a running direction of the tape and configured to control a tape-feeding direction of the tape that is fed onto the tape roll; and a movement device configured to move at least one of the push roller and the feeding direction control guide such that the tape-feeding direction conforms with a tangential direction of the tape roll at the tape feeding position.
