Knitwear Roller Winding Device Remote Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices for rollers in knitwear machines are heavy and dangerous to operate and remove, requiring manual intervention to connect and disconnect the motor from the roller, posing difficulties in installation and safety concerns.
Innovation Solution
A winding device with a rigid coupling and sliding ring mechanism, controlled by a handle and spring system, allows for remote operation to connect and disconnect from the roller shaft, featuring alignment and lifting mechanisms to facilitate easy installation and operation, and an inclinometer for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cardan shaft with telescopic shaft is used to connect the motor to the roller, then the motor can be connected to the roller shaft, but the device becomes heavy and dangerous to operate and remove
Solution Approach 1:
The patent extracts the telescopic shaft from the cardan shaft assembly, retaining only the essential cardan joints for connecting the motor to the roller. This removal of the heavy telescopic component significantly reduces the overall weight of the winding device while preserving the core functionality of motor-to-roller connection and rotation transmission.
2Ease of manufacture
If manual operation on the blocking element is required to connect/disconnect the motor from the roller, then the connection can be made, but the operator is exposed to danger and direct manual intervention is needed
Solution Approach 1:
The patent introduces a control element as an intermediary between the operator and the blocking element (sliding ring). The control element transmits the operator's input force remotely to move the sliding ring, enabling connection and disconnection operations without the operator needing to manually handle the blocking element directly, thus eliminating safety hazards while maintaining operational capability.
3Force
If the winding device is heavy, then it can transmit sufficient force, but it is difficult to install and remove
Solution Approach 1:
The patent removes the heavy telescopic shaft component from the cardan shaft assembly, significantly reducing the overall weight of the winding device. This extraction maintains the essential force transmission capability through the cardan joints while making the device much easier to install, move, and remove from the roller.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and effortless installation and operation by allowing remote control of the winding device, reducing manual labor and ensuring operator safety while maintaining efficient rotation of the roller.
Implementation Method 1
the control element 19 comprises an elastic return element 25, for example a spring, connected to the handle 19 to make it return to the starting position when it is released by the operator
Implementation Method 2
the blocking means 15 comprise a sliding ring, equipped with balls which are engaged in a groove 24 of the shaft 21

AI summary
A winding device (10) for rollers of knitwear machines is described, comprising: motor means (11); coupling means (12) rotatably connected to the motor means (11) and designed to be coupled with a shaft (21) of a roller (20) rotatable around its own axis (X'), to transmit to the roller (20) the rotation motion of the motor means; blocking means (15) designed to axially block the device (10) on the shaft (21) of the roller (20); aligning means (16) designed to align a rotation axis (X) of the coupling means (12) with the axis (X') of the shaft (21) of the roller (20), making the two axes (X and X') coincide to compensate for misalignments between the coupling means (12) and the shaft (21) of the roller (20).
