Machine Tool Module Sequencing for Smooth Workpiece Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine tools with movable and fixed modules, simultaneous movement of both movable modules to facing positions can cause interference, making smooth transfer of workpieces between modules challenging.
Innovation Solution
A control system with a restriction means and determination means is implemented to allow only one movable module to move to the facing position relative to the fixed module, based on the processing requirements, ensuring that the movement of the other module is restricted until the processing with the fixed module is completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If both movable modules are simultaneously moved to facing positions, then the workpiece transfer between modules can be performed, but interference occurs between the two movable modules making smooth transfer difficult
Solution Approach 1:
The control means applies preliminary anti-action by detecting when both movable modules are commanded to move to facing positions simultaneously, and actively preventing the second module from moving until the first module completes its movement. This preemptive restriction avoids the interference problem before it occurs, ensuring smooth module operation while maintaining efficient workpiece transfer capability
2Ease of operation
If only one movable module is allowed to move to facing position at a time, then interference between modules is prevented, but the complexity of the control system increases
Solution Approach 1:
The control means implements self-service by automatically detecting the movement status of movable modules and autonomously determining which module should be restricted. The system monitors itself, identifies potential conflicts, and applies appropriate restrictions without external intervention, thereby managing the increased control complexity through intelligent self-regulation rather than requiring complex external control mechanisms

AI summary
A machine tool includes a plurality of modules, and a control means for controlling operation of the modules, wherein the plurality of modules include a fixed module and two movable modules. The control means includes a restriction means for restricting the movement of the two movable modules for allowing only one of the movable modules to be moved to a facing position facing the fixed module; and a determination means for determining the movable module to be moved to the facing position. The control means is configured to control the operation of the plurality of modules so that, when the operation under cooperation of the fixed module and one of the movable modules has been completed, the restriction means releases the restriction of the movement of the other movable module to the facing position.
