Swivel Fork Bobbin Transfer Mechanism for Textile Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bobbin changing devices are mechanically complex and require long travel distances, resulting in significant downtime and productivity loss for processing devices due to the time spent without a bobbin on the winding station.
Innovation Solution
A bobbin changing device featuring a swivel fork with coil receiving spaces that allows for efficient transfer and alignment of bobbins using a pivoting fork, eliminating the need for complex gripper units and transverse chain conveyors, enabling shorter travel distances and faster bobbin changing times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional bobbin changing devices with gripper units and transverse chain conveyors are used, then bobbins can be transferred between conveyor and processing device, but the mechanical complexity increases and travel distances become long
Solution Approach 1:
The bobbin changing device is segmented into a conveyor device with conveyor belts for transporting bobbins and a separate swivel fork for transferring bobbins to and from the processing device. This segmentation eliminates the need for complex integrated gripper units and transverse chain conveyors, reducing mechanical complexity while maintaining efficient bobbin changing operations
Solution Approach 2:
Instead of using a transverse chain conveyor that moves perpendicular to the conveyor belts, the invention uses a swivel fork that pivots on a vertical axis to transfer bobbins. This inverted approach simplifies the mechanical structure by replacing complex chain mechanisms with a straightforward pivoting fork design, reducing both complexity and travel distance
2Productivity
If conventional bobbin changing devices with long travel distances are used, then bobbins can be transferred between conveyor and processing device, but downtime increases and productivity decreases
Solution Approach 1:
The swivel fork is positioned adjacent to the processing device and can quickly pivot to align with either the conveyor device or the processing device. This preliminary positioning eliminates long travel distances and allows for rapid bobbin transfer, significantly reducing downtime and increasing productivity
Solution Approach 2:
The swivel fork employs a quick-pivoting mechanism that allows dynamic adjustment of its position between the conveyor device and the processing device. This dynamic capability enables rapid bobbin changing by minimizing the time the processing device remains without a bobbin, thereby reducing downtime and improving productivity

AI summary
The invention relates to a bobbin changing device (1) for feeding bobbins to and/or removing bobbins from a processing system (40) which can wind a strand-like material onto a bobbin and/or from a bobbin, wherein the bobbin changing device (1) has at least one conveyor system (30) which comprises, for example, two conveyor belts (31, 32), and a swivel fork (10). At least one bobbin receiving site (21, 22) on which a bobbin can be placed is formed on the swivel fork (10). By lifting, lowering and/or swivelling the swivel fork (10) in a specific sequence and repeating same, bobbins can be fed to the processing system (40) and the conveyor system (30) and/or removed therefrom and in this way a bobbin change can be carried out. The conveyor system (30) and the movement area of the swivel fork (10) may be at least partially interpenetrating.
