Debeading Machine with Automated Cord Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing debeading machines for heavy duty tires are unsafe and tiring for operators due to the high weight and dimensions of the tires, requiring improved safety and reduced operator effort during the debeading process.
Innovation Solution
A debeading machine with a frame, support means for the tire, a hook for extracting the metal cord, and a movable element that detaches the cord from the hook, along with clamping means to secure the sidewall against a supporting plate, allowing for safe and efficient extraction of the metal heel reinforcement cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of the steel cord from the hook is performed by the operator, then the cord can be extracted from the tire, but the operator is exposed to safety risks and experiences fatigue due to the high weight and dimensions of the cord
Solution Approach 1:
The system performs self-service by automatically detaching the cord from the hook through the movable element, eliminating the need for operator intervention in the cord removal process. The movable element automatically engages with the hook and detaches the cord when the hook is in the extraction position, making the system serve itself rather than requiring human operation.
Solution Approach 2:
The movable element acts as an intermediary between the hook and the cord detachment process. Instead of the operator directly handling the heavy cord, the movable element mediates the detachment by engaging with the hook and automatically releasing the cord, thereby protecting the operator from direct contact with the hazardous heavy object.
2Productivity
If the hook is used to extract the steel cord from the tire sidewall, then the cord can be removed from the tire structure, but the high pulling forces required create safety risks for the operator
Solution Approach 1:
The invention extracts the dangerous function of cord detachment from the operator's manual action and transfers it to the automated movable element. By taking out the hazardous operation of removing the cord from the hook and assigning it to the automated system, the operator is removed from the zone of high forces and potential harm.
Solution Approach 2:
The movable element serves as an intermediary that handles the high forces required for cord extraction. It engages with the hook and performs the forceful detachment operation, acting as a buffer between the high-force extraction process and the operator, thereby eliminating direct operator exposure to harmful forces.
3Reliability
If the operator manually handles the extracted cord, then the cord can be disposed of separately, but the process becomes tiring and time-consuming
Solution Approach 1:
The system performs self-service in the complete cord removal and disposal process. The movable element automatically detaches the cord from the hook and directs it to the disposal zone, eliminating the need for operator time and effort in handling the cord after extraction. The system serves itself by completing the entire cord removal sequence without human intervention.
