Under-Table Tool Magazine for Compact Sanding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanding machines with tool magazines require additional floor space, limiting their compactness and efficiency due to the need for a clear sector to prevent interference with the operating area.
Innovation Solution
A tool magazine designed as a wheel is positioned underneath the machine table, allowing the sanding spindle to access tool holders laterally, eliminating the need for additional floor space and enabling compact sander designs with rotational capabilities for enhanced tool exchange and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool magazine is arranged next to the operating area, then tool exchange is enabled, but the floor space required increases
Solution Approach 1:
The tool magazine is relocated from a horizontal arrangement next to the operating area to a vertical arrangement underneath the machine table. This dimensional change allows the tool magazine to utilize the vertical space under the table, eliminating the need for additional horizontal floor space while maintaining tool exchange functionality through lateral projection of the exchange position.
2Object-affected harmful factors
If the tool magazine wheel shows a clear sector to coincide with the operating area, then interference is prevented, but the number of tool holders is limited
Solution Approach 1:
By moving the tool magazine to a vertical position underneath the machine table, the clear sector requirement is eliminated. The tool magazine wheel can rotate fully without interfering with the horizontal operating area, as it operates in a different spatial plane. This allows all tool holders to be utilized without needing to reserve a clear sector.
3Area of stationary object
If the tool magazine is arranged underneath the machine table, then floor space is minimized, but the operating spindle must be displaced towards the bottom
Solution Approach 1:
The operating spindle is made dynamically movable in the vertical direction through the Z-sled mechanism. The Z-sled enables the spindle to be displaced towards the bottom to access the tool magazine underneath the machine table, and then returned to its working position. This dynamic capability allows the system to adapt between processing mode and tool exchange mode.

AI summary
A sanding machine, with a machine bed, two vertical supports arranged laterally at the machine bed, with a bridge displaceable on the vertical supports in a horizontal, linear Y-axis, with an X-sled displaceable at the bridge in a horizontal, linear X-axis, with a Z-sled displaceable at the X-sled in a vertical, linear Z-axis, with an operating spindle supported at the Z-sled, particularly a sanding spindle, with a machine table and a magazine wheel comprising tool holders for sanding disks, and which is rotational about an axis parallel in reference to the Z-axis, with the operating spindle being able to remove a tool from a tool holder and place it there when this tool holder is rotated into an exchange position, with the tool magazine being arranged underneath the machine table and in the area of the exchange position.
