Sweeping Workpiece Fixing Device for Sheet Metal Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical arrangements for processing metal sheets face inefficiencies in unloading processed workpieces due to separate drives for loading and unloading devices, leading to structural complexity and space inefficiencies.
Innovation Solution
A mechanical arrangement with a dual-use drive system, where the workpiece fixing device of the sweeping device is connected to the workpiece holding member of the loading device, allowing for shared movement and reduced component count, enabling efficient unloading through a sweeping mechanism that utilizes the workpiece support's movability and includes selectively activatable fixing members for secure sweeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate drives are used for loading and unloading devices, then each device can operate independently, but structural complexity increases and space efficiency decreases
Solution Approach 1:
The patent combines the drive mechanisms for the loading device (workpiece holding member) and unloading device (workpiece fixing device) into a single shared drive system. The workpiece support serves as a common moving element that carries both devices, eliminating the need for separate drives and reducing structural complexity while maintaining independent operational capability through coordinated control
2Ease of operation
If separate drives are used for loading and unloading devices, then each device can operate independently, but space efficiency decreases
Solution Approach 1:
By merging the loading and unloading devices onto a single workpiece support structure with a shared drive, the patent reduces the spatial footprint required for independent operation. The compact integrated design allows both functions to coexist in a smaller area compared to separate drive systems
3Productivity
If a sweeping mechanism is used for unloading, then unloading efficiency improves, but interference with upper processing operations may occur
Solution Approach 1:
The workpiece support is designed as a dynamic element that can move horizontally to enable the sweeping action. This movability allows the support to shift position during unloading, creating clearance between the sweeping mechanism and the upper processing area, thereby preventing interference while maintaining high unloading efficiency
4Productivity
If workpiece fixing device is moved into sweeping position, then unloading can be performed, but structural complexity increases
Solution Approach 1:
The workpiece support serves multiple functions: it supports the workpiece during processing, carries both the loading and unloading devices, and enables the sweeping motion for unloading. This multi-functionality eliminates the need for dedicated complex movement mechanisms, as the support itself performs the sweeping action through its inherent movability

AI summary
Workpieces are unloaded from a workpiece support of a sheet metal workpiece processing apparatus by positioning a blank sheet metal workpiece over a processed workpiece supported on a workpiece support, with the blank workpiece releasably held by a workpiece loader, activating a workpiece fixing device to engage an edge of the processed workpiece, and performing a relative sweeping movement between the workpiece fixing device and the workpiece support whereby the engaged processed workpiece is prevented from remaining on the workpiece support and is thereby unloaded. The workpiece fixing device is moved relative to the processed workpiece while the blank sheet metal workpiece is positioned over the processed workpiece.
