Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for orienting sleeves in textile machines are limited, as they can only handle conical sleeves and require complex mechanisms to orient non-conical sleeves, which complicates the automatic exchange of sleeves in textile machines.
Innovation Solution
A method and device that rotate sleeves by 90° transversely to their axis using a transport device, where one side of the sleeve contacts the transport device while the other side is either stationary or moved more slowly, generating torque for rotation, allowing for easy orientation of non-conical sleeves with minimal effort and space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods using two conveyor belts and conical sleeves are used, then conical sleeves can be oriented horizontally, but the method cannot be applied to non-conical sleeves and requires complex mechanisms
Solution Approach 1:
The transport device is designed to handle both conical and non-conical sleeves through a universal mechanism. By using a single transport device that can rotate sleeves of any shape through differential movement, the system eliminates the need for separate mechanisms for different sleeve types, thereby achieving versatility without increasing complexity
Solution Approach 2:
The invention extracts the essential function of sleeve orientation from the complex two-conveyor-belt system and implements it through a single transport device with rotational capability. This simplifies the overall system by removing unnecessary components while maintaining the core functionality of orienting various sleeve types
2Manufacturing precision
If complex mechanisms with multiple conveyor belts and reversing elements are used, then tube orientation can be achieved, but the device complexity and space requirements increase
Solution Approach 1:
The invention merges the functions of multiple conveyor belts, reversing elements, and orientation mechanisms into a single integrated transport device. This transport device simultaneously performs transport, rotation, and orientation functions, reducing the number of components while maintaining precise orientation control through differential movement of the first and second sides
3Ease of operation
If multiple transport devices are used to rotate and transport tubes, then proper orientation is achieved, but the space requirements and device complexity increase
Solution Approach 1:
The single transport device is designed to perform multiple functions including transport, rotation, and orientation of sleeves. By integrating these functions into one device rather than using separate mechanisms, the system achieves ease of operation while minimizing the space required for the overall mechanism

AI summary
The invention relates to a method and an apparatus (3) for rotating a tube (4) for packages of a textile machine (1). In the method, the tube (4) is removed from a tube magazine (6) in a manner oriented in a first direction (10), rotated substantially through 90° transversely to its tube axis into a second direction (12), and transported onward in the second direction (12) by a transporting device (11). According to the invention, a first side (12) of the tube (4) comes into contact with a transporting device (11) that is moved in the second direction (12) transversely to the first direction (10). In the process, the transporting device (11) moves this first side (12) transversely to the tube axis. At the same time, relative to the first side (13), a second side (14) of the tube (4) is not moved or is moved at least slower transversely to the tube axis, such that the tube (4) executes a rotation transversely to the tube axis. The apparatus (3) according to the invention is designed to carry out the method.
