Segmented Tool Arm for Tire Mounting Machine Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assembling-disassembling machines face issues with tool displacement causing unbalance and requiring significant space, leading to increased production costs and limited operator workspace, as well as slow and labor-intensive tool movement.
Innovation Solution
The machine incorporates rotating and sliding support means between the upright and tool-carrying arm, allowing the tool to be shifted and angularly displaced between working and rest positions with minimal effort, without causing machine unbalance or requiring additional space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upright is rotated about its vertical axis to move the tool from working to rest position, then the tool can be displaced away from the working area, but lateral protection is required which increases production costs
Solution Approach 1:
The tool-carrying arm is segmented into a fixed part on the upright and a movable tool portion that can be independently rotated and displaced. This allows the tool to be moved away from the working area without requiring protection for the entire upright structure, reducing the complexity and cost of protective measures.
Solution Approach 2:
The tool is extracted from the upright structure through a detachable connection mechanism. The tool-carrying arm can be completely removed or displaced laterally from the upright, eliminating the need for lateral protection of the upright itself while still allowing tool operation.
2Ease of operation
If the upright is inclined rearwards after being partly rotated about a horizontal axis, then the tool can be moved to rest position, but a large area behind the machine must be provided which increases costs
Solution Approach 1:
Instead of moving the tool in a single horizontal dimension by rotating the entire upright, the solution uses a two-dimensional movement: first rotating the tool-carrying arm about a vertical axis, then displacing it horizontally. This compact movement pattern requires minimal space behind the machine while achieving the same tool repositioning.
3Ease of operation
If the upright with tool-carrying arm is rotated to move the tool, then the tool can be displaced, but a relatively large weight must be displaced causing substantial unbalance in the machine
Solution Approach 1:
The system is segmented into a heavy fixed upright and a lighter movable tool-carrying arm. By rotating only the arm portion rather than the entire upright, the weight to be displaced is minimized, reducing unbalance forces while maintaining tool displacement capability.
4Ease of operation
If the upright is rotated to move the tool between working and rest positions, then the tool can be repositioned, but the times for tool opening are relatively long since the weight is heavy and slow opening is required to prevent machine overturning
Solution Approach 1:
The tool-carrying arm is segmented as a separate movable component with significantly less weight than the full upright. This allows rapid rotation and repositioning of the tool without the safety concerns of displacing heavy upright mass, thereby increasing tool opening speed and productivity.
5Ease of operation
If the tool is displaced away from working position by rotating the upright, then the tool is outside operator area, but the working area available for operator is limited even after upright has been overturned rearwards
Solution Approach 1:
The tool is moved out of the operator's vertical working space by rotating it upward about a horizontal axis after initial lateral displacement. This three-dimensional repositioning completely removes the tool from the operator's two-dimensional working plane, maximizing available working area while maintaining safety.

AI summary
The present invention relates to an assembling-disassembling machine provided with a base, a rotating support device (4) for a wheel rim or tyred wheel, an upright or column element (2) extending upwards from the base, and at least one mounting/dismounting tool (6) supported by the upright or column element (2) and mounted on one end of a tool carrying arm (5) in order to transversely extend from the upright element (2). The assembling-disassembling machine also comprises rotating and shifting support means located between the upright or column element (2) and the tool-carrying arm (5) at an upper level with respect to the rotating support device (4), whereby said tool-carrying arm (5) can be rotated and shifted with respect to the upright or column element (2) between a working position, in which the tool (6) is close to the rotating support device (4) and at least one rest position far from the rotating support device (4).
