Solution Overview

Problem

Existing winding machine fixing mechanisms require manual or mechanical lever actuation for fixing and releasing the winding sleeve, which limits operational efficiency and space utilization in densely arranged factory settings.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual or mechanical lever actuation is used for fixing and releasing the winding sleeve, then the fixing mechanism is simple in structure, but the operational efficiency is limited and space utilization is reduced in densely arranged factory settings

Engineering Contradiction:

Improveoperational efficiencyVSAvoidfixing mechanism structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The motion control system is pre-programmed with the sequence of operations for fixing and releasing the winding sleeve. The controller automatically executes these pre-planned actions in the correct sequence, eliminating the need for manual lever actuation and improving operational efficiency while maintaining a relatively simple mechanical structure

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The fixing mechanism is designed to automatically perform the fixing and releasing operations without requiring external manual intervention. The motion control system coordinates the actuating elements to self-regulate the clamping and releasing processes, thereby increasing productivity while keeping the device structure manageable

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual lever actuation is used for fixing and releasing the winding sleeve, then the mechanism requires less automation components, but the effort required for coupling and decoupling is high

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The manual mechanical lever actuation system is replaced with an automated motion control system that uses programmed sequences and automated actuating elements. This substitution eliminates the need for manual effort in coupling and decoupling operations while introducing electronic control components to manage the fixing mechanism

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If traditional fixing mechanisms are used, then the space requirements are larger for lever actuation, but the operational safety is reduced in densely arranged factory settings

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The manual lever actuation components are extracted or removed from the fixing mechanism design. The operational safety functions are instead implemented through automated sensors, control systems, and programmed safety sequences that require minimal physical space, allowing for compact arrangement in densely packed factory environments while maintaining or improving operational safety

Inventive Principle:

Scientific EffectSpring force: Spring

Implementation Method 3

The blades thereby slide along the grooves of the conical lateral surface of the catch, whereby these are spread apart and pressed against the inner surface of the winding sleeve. In the fixing position brought about in this way, the bobbin is frictionally secured by pressing the blades against the inner surface of the winding sleeve.

AI summary

The invention relates to a winding machine (1) with a winding machine fixing mechanism (44) for fixing a winding sleeve (4) on a winding spindle (3). The winding machine fixing mechanism (44) can be actuated by use of a motion control. By this motion-controlled actuation, the winding machine fixing mechanism (44) can be transferred from the release position into a fixing position and/or from a fixing position into a release position. During the motion control, a catch (5) is entrained by the movement of the winding sleeve (4). This catch then causes the actuation of the winding machine fixing mechanism (44).
