Bobbin Stocker Layout for Low-Height Winding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices require additional space above the device to accommodate the movement of the stocker, leading to an increased height, which is undesirable.
Innovation Solution
The stocker is designed to move linearly between standby and supply positions, positioned on one side of a vertical plane relative to the cradle, avoiding spaces above the device, and equipped with regulatory portions to ensure bobbin transfer without interference.

Engineering Contradiction Analysis
1Ease of operation
If the stocker is moved from standby position to supply position using a rotational mechanism, then the bobbin can be supplied to the cradle, but additional space above the winding device is required, increasing the overall height
Solution Approach 1:
The patent changes the movement dimension of the stocker from vertical (rotational arc) to horizontal (linear). The stocker moves linearly along the width direction of the machine between standby and supply positions, eliminating the need for vertical clearance space and reducing overall device height while maintaining bobbin supply functionality
2Length of stationary object
If the stocker is positioned to move linearly between standby and supply positions, then the height of the winding device is reduced, but the stocker must be precisely positioned to avoid interference with other components
Solution Approach 1:
The patent divides the winding device into distinct functional zones: the stocker operates in the width direction on one side of the vertical plane, the cradle operates at the release position on the other side, and the package storage unit is positioned separately. This spatial segmentation allows linear movement without complex interference avoidance mechanisms
Solution Approach 2:
The patent introduces a vertical plane as a spatial reference and separator. The stocker is positioned on one side of this plane while the cradle and package storage unit are on the other side, using the plane as an intermediary to organize component布局 and simplify movement paths

AI summary
An object of the present invention is to suppress the increase in height of a winding device. A winding device 21 includes a cradle arm 30, a package storage unit 50 provided on one side of a vertical plane F passing an axial center of a bobbin holder 70 supported by the cradle arm 30 at a release position, a stocker 60 provided on the other side of the vertical plane F, and a movement mechanism 80 configured to move the stocker 60 between a standby position and a supply position. The movement mechanism 80 is configured to move the stocker 60 linearly between the standby position and the supply position.
