Rotating Head Tyre Mounting Machine for Operator Freedom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre mounting and dismounting machines require precise alignment and movement of multiple columns, limiting operator freedom and efficiency, especially when performing debeading, dismounting, and mounting operations on wheels of varying sizes and types.
Innovation Solution
A tyre mounting/dismounting machine with a rotating head and sliding column system, where three tools (debeader, mounting, and dismounting tools) are positioned radially and can be rotated to a fixed work position, eliminating the need for repeated alignment and allowing for flexible operation on different wheel sizes.

Engineering Contradiction Analysis
1Ease of operation
If two columns are used to support the tools, then the tools can be positioned for debeading, dismounting and mounting operations, but the operator's freedom of movement is limited and the machine structure becomes more complex
Solution Approach 1:
The patent merges the functions of two separate columns into a single column structure. The first arm supports both the upper and lower debeader tools, while the second arm supports both the dismounting and mounting tools. This consolidation reduces the number of structural columns from two to one, eliminating obstacles in the operator's workspace while maintaining all necessary tool positioning capabilities.
Solution Approach 2:
Each arm in the patent serves multiple functions: the first arm handles both debeading operations (upper and lower tools), and the second arm handles both dismounting and mounting operations. This multi-functionality allows a reduced number of columns to support all four tools, improving operator accessibility without compromising operational capability.
2Productivity
If two columns are moved to achieve correct tool positioning, then the operations can be performed, but the time required for positioning increases and productivity decreases
Solution Approach 1:
The tools are pre-positioned on their respective arms in fixed reciprocal positions before operation begins. The arms themselves are pre-configured with the tools at correct orientations. When an operation is needed, the arm simply rotates to a predetermined angular position rather than requiring complex real-time alignment of multiple columns, significantly reducing positioning time.
Solution Approach 2:
The patent employs dynamic rotation of the arms to achieve tool positioning. Instead of moving multiple columns independently to achieve alignment, the system rotates the entire arm assembly to a specific angular position where the required tool is automatically in the correct working position. This dynamic approach is faster and more efficient than static multi-column alignment.
3Ease of manufacture
If the tools are positioned on two columns, then the machine can perform all operations, but the structural complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines the tool-carrying functions into two arms instead of requiring two separate columns. Each arm integrates multiple tools (first arm: upper and lower debeaders; second arm: dismounting and mounting tools), reducing the overall structural complexity and simplifying manufacturing while maintaining full operational capability.
Solution Approach 2:
The arms are designed as universal carriers that can support and position multiple different tools. This multi-functional design reduces the total number of structural elements needed, as each arm serves multiple purposes across different operations, thereby simplifying the overall machine construction and reducing manufacturing complexity.

AI summary
A tire mounting/dismounting machine (1), comprising a base (2), rotating means (3) for supporting and blocking a wheel (100) and a column (4) associated to the base (2), a first arm (7) and a second arm (8) being slidably mounted on the column (4), an upper first debeader tool (13) and a lower second debeader tool (9) being mounted respective at free ends of each arm (7, 8). Mounted at the free end of the first arm (7) is a head (10) which is rotatable with respect to an axis (Y), from which head a mounting tool (11), a dismounting tool (12) and the first debeader tool (13) project, the tools (11, 12, 13) being mounted in reciprocal positions such that the tools (11, 12, 13) do not interfere with one another and such that by rotating the head (10) with respect to the first arm (7) a same work position can be reached for each of the tools (11, 12, 13). Means for blocking (14, 15, 16, 17) are associated to the head (10) in three different positions, a same work position for each of the tools (11, 12, 13) corresponding to each of the three different positions.
