Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spring tube winding process is heavily dependent on worker skill for precise cord intersection angles, leading to inconsistent buffering force and product quality, and the materials often stick to the winding roller, making separation difficult and affecting the final product quality.
Innovation Solution
A spring tube winding machine with a cylindrical winding roller featuring uneven portions and discharge holes for compressed air, along with a table with reference lines for setting the correct cord intersection angles, ensures accurate cord arrangement and easy material separation by pneumatically floating the materials off the roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a worker manually stacks and winds spring tube materials on a winding roller, then the process is simple and equipment-free, but the cord intersection angle cannot be precisely controlled, leading to inconsistent buffering force and product quality
Solution Approach 1:
The patent applies preliminary action by pre-marking reference lines at the correct 45-degree angle on the table surface before the winding operation. This allows the worker to align the cord topping sheets with the reference lines, ensuring precise cord intersection angles without requiring complex measurement or adjustment mechanisms during the actual winding process.
Solution Approach 2:
The patent introduces an intermediary element - the reference line marking on the table - that mediates between the simple manual operation and the requirement for precise angle control. The reference line serves as a visual guide that translates the complex angular requirement into a simple alignment task, eliminating the need for sophisticated positioning mechanisms.
2Ease of operation
If spring tube materials are stacked and wound in close contact on a winding roller, then the cylindrical form is achieved, but the materials stick to the roller and become difficult to separate, requiring forceful pulling that varies the arranged angle and reduces product quality
Solution Approach 1:
The patent applies preliminary action by injecting compressed air into the discharge holes in the winding roller before the spring tube materials are fully wound and cooled. This pre-separation action prevents the materials from adhering strongly to the roller, making them easy to remove without forceful pulling that would distort the cord arrangement.
Solution Approach 2:
The patent uses pneumatics by incorporating a compressed air supply system with discharge holes in the winding roller. The compressed air is injected through the roller to create a pneumatic barrier between the roller surface and the spring tube materials, preventing adhesion and enabling easy separation while maintaining the precision of the cord intersection angles.

AI summary
Disclosed therein is a spring tube winding machine including: a winding roller (10) formed in a cylindrical shape to wind a first rubber sheet (T1), a first code topping paper (C1), a second code topping paper (C2) and a second rubber sheet (T2), which are the spring tube materials, in order, the winding roller (10) including an uneven portion (12) formed on the outer circumferential surface thereof, a nozzle (14) disposed at an end for injecting compressed air, and a plurality of discharge holes (16) for ejecting compressed air injected through the nozzle (14) outwardly from the inside; and a table (20) having a reference line (22) for setting a seating angle in such a fashion that the spring tube materials wound on the winding roller (10) are seated in an unfolded state and the codes (C) embedded in the first code topping paper (C1) and the second code topping paper (C2) are intersected with each other. The spring tube materials are seated at correct positions and wound on the winding roller through the reference lines marked on the table so as to be exactly arranged at the preset code intersection angle, and so, the spring tube winding machine can keep even quality of the spring tube and even buffering force. Moreover, the spring tube winding machine enables the spring tube materials to be easily removed from the winding roller after completion of the stacking and winding process because the discharge hole is formed to spray the compressed air in the outward direction from the inside.
