Modular Sleeve Fitter for Rapid Retooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for fitting sleeves onto electric wires require extensive retooling, involving the exchange of many sleeve-specific machine parts or tools, leading to long changeover times and increased risk of confusion.
Innovation Solution
The device employs modular components, allowing for quick retooling by swapping sleeve-specific modules rather than individual tools, reducing confusion and shortening downtime by preparing the next lot of sleeves while fitting the current lot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If many sleeve-specific machine parts or tools are exchanged during retooling, then the device can be adapted to different sleeve types, but the retooling time increases significantly
Solution Approach 1:
The device is divided into modular components, with each sleeve type having its own dedicated module containing the necessary machine parts and tools. This segmentation allows individual modules to be quickly swapped without exchanging numerous individual parts, directly reducing retooling time while maintaining adaptability to different sleeve types.
Solution Approach 2:
Complete sleeve-specific modules are pre-assembled with all necessary machine parts and tools configured for specific sleeve types. This preliminary preparation eliminates the need to individually assemble or adjust multiple parts during retooling, enabling rapid module exchange and significantly reducing changeover time.
2Reliability
If many individual sleeve-specific parts are exchanged, then the correct parts can be selected for each sleeve type, but the risk of confusion and errors increases
Solution Approach 1:
Multiple sleeve-specific machine parts and tools are merged into single integrated modules. Each module contains all necessary components for a specific sleeve type, eliminating the need to manage and select individual parts separately. This merging reduces confusion and errors while maintaining the ability to correctly configure the device for different sleeve types.
3Adaptability or versatility
If the device is designed to handle multiple sleeve types with many adjustable parts, then versatility is improved, but the complexity of retooling and preparation increases
Solution Approach 1:
The device is segmented into standardized modular units, each designed for specific sleeve types. This segmentation simplifies the manufacturing of individual modules while maintaining overall versatility, as each module can be independently manufactured and then quickly installed without complex preparation or adjustment procedures.

AI summary
A sleeve-fitter includes a sleeve module, a fitting module, a control and a base module. The fitting module and control are part of the base module. In operation, a centering pin and a round hole cooperate when the sleeve module is in contact with the base module and the sleeve module can be separated from the base module by a lever. The sleeve module includes a sleeve container with a drum, a filling funnel with a cover, a support for accommodating sleeve-specific machine parts and/or tools, and a feeder rail arranged on a linear vibratory feeder. A drive arranged on the base module imparts rotational movement to the drum which then feeds sleeves onto the feeder rail. This sleeve-fitter results in short retooling times and therefore short downtimes.
