Sectional Warp Beam Clip for Thread Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for combining partial warp beams to form a warp beam are laborious and time-consuming, often resulting in threads being subjected to lateral tensile forces, which reduces the usable length and requires significant operator effort.
Innovation Solution
A sectional warp beam with a clip and fastening device that allows for secure grasping and fixing of threads across their width, eliminating the need for bundle formation and minimizing transverse forces, combined with a transport device that conveys the clip with the thread bundle to the assembly device, reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If threads are manually bundled and pulled from the partial warp beam, then the thread sheet can be transferred to the assembly device, but lateral tensile forces are applied to the threads and significant manual effort is required
Solution Approach 1:
A clip is introduced as an intermediary device between the operator and the thread sheet. The clip grasps the entire width of the thread sheet and is attached to the partial warp beam, allowing the operator to pull the clip rather than directly handling the threads. This intermediary mechanism distributes the pulling force and eliminates the need for manual bundling, significantly reducing lateral tensile forces on individual threads while maintaining ease of operation.
2Reliability
If the clip is attached to the partial warp beam with a fastening device, then the clip remains secured during handling and transport, but the fastening device must be released at the assembly device
Solution Approach 1:
The fastening device is segmented into two functional parts: a fastening mechanism that secures the clip to the partial warp beam during handling and transport, and a release mechanism that operates at the assembly device. This segmentation allows the system to maintain reliable clip securing during critical phases while enabling easy release when needed, without requiring an overly complex integrated system throughout the entire process.
3Reliability
If the clip length is extended to clamp between side plates, then the clip can be securely fixed to the partial warp beam, but the clip must be compact when not in use
Solution Approach 1:
The clip incorporates a telescopic or extendable structure that allows it to dynamically change its length. When the clip needs to be secured to the partial warp beam between the side plates, it extends to the required length for reliable fixation. When not in use or during transport, the clip retracts to a compact form, minimizing its volume and preventing interference with handling operations. This dynamic adaptability resolves the contradiction between fixation reliability and storage compactness.
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
Facilitates efficient preparation and handling of thread sheets by eliminating lateral stresses and reducing manual labor, allowing for seamless integration into the assembly process without interfering with the partial warp beam's handling.
Implementation Method 1
The spring arrangement can be prestressed, for example, in the longitudinal direction of the clip, that is to say in the width direction of the sheet of threads of the partial warp beam. When the clip is to be fastened in the partial warp beam, it is compressed somewhat in its longitudinal direction, placed between the side plates and then relaxed. The clip is thus fixed with sufficient certainty in the partial warp beam.
Implementation Method 2
The clip is preferably provided at each of its two ends with an end piece made of a rubber-elastic material. Such an end piece increases the friction between the clip and the side plates without requiring any major effort.
