Solution Overview
Problem
Existing cable processing machines face challenges in efficiently handling long cable sections, leading to increased processing time and mechanical inefficiencies, particularly with swivel machines and transfer machines that require lengthy cable trays and serial processing.
Innovation Solution
A cable processing machine with a winder and laying unit that forms a coil with a controlled motor and belt drive, allowing parallel processing of cable ends and simultaneous winding, cutting, and tying, reducing the overall processing time by integrating the winder and laying unit as an integral part of the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate winding devices are used downstream of the cable processing machine, then cable sections can be wound into coils, but the cycle time or total processing time increases due to serial processing
Solution Approach 1:
The patent combines the winding device and laying unit with the cable processing machine into a single integrated system. The winding device is positioned between the cutting/stripping unit and the second swivel arm, allowing cable sections to be wound into coils and processed simultaneously within one machine cycle, eliminating the time loss associated with separate downstream winding operations
Solution Approach 2:
The integrated design enables continuous processing where the cable is fed through cutting, stripping, winding, and laying operations without interruption. The winder and laying unit operate concurrently with the processing stations, maintaining continuous useful action throughout the entire cable section transformation process
2Ease of operation
If cable processing machines use swivel arms with cable trays as long as the cable section, then cable ends can be processed, but the machine becomes lengthy and mechanically inefficient
Solution Approach 1:
The patent transitions from linear cable tray arrangements to a compact integrated structure where the winder and laying unit operate in a different spatial configuration. The cable section is wound into a coil format, allowing processing to occur in a compact footprint rather than requiring a linear tray as long as the cable section itself
Solution Approach 2:
The swivel arms maintain their pivoting capability for cable end processing, but the overall system uses dynamic coil winding and laying operations to accommodate long cable sections without requiring proportionally long fixed structures. The machine adapts its configuration during operation rather than requiring static lengthy components
3Productivity
If transfer machines use linearly movable transport units, then cable sections can be transported, but multiple loop-shaped cables lying on top of each other cause high cable tensile forces during rapid transport
Solution Approach 1:
The patent winds the cable section into a coil configuration with controlled curvature radius, eliminating the loop-shaped arrangements that cause cables to lie on top of each other. The coil structure distributes mechanical stresses evenly and allows rapid transport without generating excessive tensile forces, as the curved configuration naturally accommodates movement dynamics

AI summary
In this swiveling cable processing machine (10), a winder (17) is arranged between a cutting/stripping unit (18) and a second swivel arm (19). The cable section processed at the leading cable end is wound onto a winding disc of the winder (17). After processing, the leading cable end of the cable section is gripped by the winder (17). A belt drive (11) then advances the cable (13) by the desired length of the cable section, and the winder simultaneously winds the advanced cable into a coil. After the winding process, a linearly movable discharge unit (23) grips the coil, and the winder disc releases the coil. After processing the trailing cable end, the discharge unit (23) continues moving in the cable feed direction to the discharge point (24). During the processing of the trailing cable end and on the movement to the discharge point (24), the coil is bundled.
