Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for bonding rubber strips around non-linear cylinder-like wound bodies require large space and complex gyrating mechanisms, leading to inefficiencies and safety concerns due to limited working space and potential collisions.
Innovation Solution
A bonding device with a rotatably guided transporting conveyor and a pressing conveyor, featuring a straight-line transporting surface centerline and tiltable guiding rollers, allows for accurate application of rubber strips without deformation and reduces the device's spatial requirements by eliminating unnecessary gyrating motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transporting conveyor gyrates around the shaft center in the perpendicular Z-axis direction to follow the non-linear cylinder-like profile, then the rubber strip can be accurately applied without deformation, but the device occupies large space and limits worker working space
Solution Approach 1:
The transporting conveyor is segmented into multiple independent guiding rollers (first through fourth guiding rollers) that can be individually tilted around the transporting surface width centerline. This segmentation allows each roller to independently adjust to the non-linear cylinder-like profile while maintaining a compact overall structure, eliminating the need for large-space gyrating motion.
Solution Approach 2:
The guiding rollers are made tiltable around the transporting surface width centerline, allowing dynamic adjustment of the transporting surface orientation to match the non-linear profile. This dynamic adaptation enables accurate rubber strip application without requiring the entire conveyor to gyrate in a large perpendicular space.
2Manufacturing precision
If the transporting conveyor gyrates around the shaft center to follow the wound body profile, then accurate rubber strip application is achieved, but the working space of workers is limited due to collision risk
Solution Approach 1:
The conveyor structure is divided into multiple independent guiding rollers that can be individually tilted, replacing the monolithic gyrating conveyor. This segmentation creates a compact configuration that reduces the gyration radius and eliminates collision risks with workers while maintaining profile-following capability.
Solution Approach 2:
Instead of gyrating around the shaft center (Z-axis rotation), the invention tilts the guiding rollers around the transporting surface width centerline (lateral tilting). This dimensional change in the tilting axis allows the conveyor to adapt to the non-linear profile without occupying perpendicular space that would limit worker access.
3Manufacturing precision
If the transporting surface forms a twistable twisting structure to follow the non-linear profile, then accurate rubber strip application is achieved, but the device complexity increases
Solution Approach 1:
The complex twisting surface is achieved by segmenting the conveyor into multiple independent guiding rollers that can be individually tilted. Each roller simply performs a basic tilting motion around the transporting surface width centerline, avoiding the need for complex integrated mechanisms while collectively creating the required twisting surface profile.

AI summary
A rubber strip is bonded with high accuracy to the surface of a non-linear cylinder-like wound body. The space occupied by the device is reduced. Provided is a transporting conveyor having a transporting belt guided rotatably by guiding rollers. A transporting surface of the transporting belt is provided with a transporting surface width centerline extending in a straight line over the entire length thereof. The guiding rollers are distributed into forward-side guiding rollers and backward-side guiding rollers in the transporting direction. Since the forward-side guiding roller is held tiltibly around the transporting surface width centerline, the transporting surface forms a twistable twisting transporting surface portion between a forward-side transporting surface portion supported by the forward-side guiding roller and a forward-side transporting surface portion supported by the backward-side guiding roller.
