Automated Workpiece Transfer Between Pallets in Horizontal Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for switching or re-clamping semi-machined workpieces in horizontal machining centers are time-consuming and laborious, particularly for large and heavy workpieces made of light metals, requiring manual intervention and reducing efficiency.
Innovation Solution
The method involves pivoting the pallet with the semi-machined workpiece to a turned transfer position where the machined side faces outwards, allowing for automatic transfer to a second pallet with a clamping apparatus, eliminating the need for manual handling and enabling quick, unmanned operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual transfer of workpiece between pallets is used, then flexibility in handling is maintained, but time consumption and labor requirements increase significantly
Solution Approach 1:
The system enables automatic self-service workpiece transfer between pallets using robotic manipulation and automated clamping mechanisms, eliminating the need for manual intervention while maintaining operational flexibility
Solution Approach 2:
Manual mechanical handling is replaced with an automated system combining robotic arms, automated clamping apparatus, and computer-controlled coordination to perform workpiece transfer operations
2Ease of manufacture
If manual transfer equipment and personnel are used, then workpiece handling is achievable, but operational complexity and labor costs increase
Solution Approach 1:
Multiple separate functions (workpiece transfer, clamping, positioning) are merged into an integrated automated system where the robotic arm and clamping apparatus work in coordinated unity, reducing the need for separate auxiliary equipment
Solution Approach 2:
The automated system is designed with universal capabilities to handle different workpiece types and sizes through programmable robotic manipulation and adjustable clamping mechanisms, eliminating the need for specialized equipment for each operation
3Adaptability or versatility
If workpiece switching is performed manually, then adaptability to different workpiece configurations is maintained, but productivity decreases
Solution Approach 1:
The system incorporates dynamic, programmable robotic manipulation that can adapt to different workpiece configurations through software control, enabling rapid reconfiguration without manual intervention and maintaining high productivity
Solution Approach 2:
The automated system changes operational parameters (robotic path, clamping force, positioning coordinates) programmatically to adapt to different workpiece types, maintaining versatility while eliminating manual setup time

AI summary
In a method for switching a workpiece, which is fixed on a pallet, after one workpiece side has been machined in a horizontal machine tool, the pallet is brought into a transfer position in which the machined side of the workpiece faces in a direction toward a pallet support, an additional pallet is provided there, and the workpiece is transferred, with the machined side first, onto a clamping apparatus of the additional pallet and is guided back into the tool with the additional pallet. In a system for switching, the pallet support has a positioning device by means of which the semi-machined workpiece can be transferred, with the machined side first, to a clamping apparatus of the additional pallet.
