Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to adequately consider the suction state when products are cut out from a workpiece, leading to issues such as slanted or deflected products getting caught in residual workpiece material.
Innovation Solution
A control data creation device that specifies the suction state for each suction position by calculating a suction gravity center, optimizing the suction positions to minimize the distance between the suction gravity center and the product gravity center, ensuring stable product removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suction control is used without considering suction state for each position, then the control system is simple, but the product becomes slanted or deflected and gets caught in residual workpiece material
Solution Approach 1:
The invention divides the suction control into multiple discrete suction positions (first suction position, second suction position, etc.) along the transport path. Each position has its own suction force evaluation index calculated based on the product shape data and pad arrangement. This segmentation allows precise control of suction state at each position without requiring complex overall control systems.
Solution Approach 2:
The invention performs preliminary calculation of suction force evaluation indices for all suction positions before actual product transport. The control data creation device pre-processes the product shape data to determine optimal suction forces at each position, preventing product deflection and catching issues before they occur during transport.
2Reliability
If suction positions are not optimized, then the handling process is simple, but the product is caught in residual workpiece material
Solution Approach 1:
The invention introduces a feedback mechanism where the suction force evaluation index is calculated based on the product shape data and pad arrangement, then used to adjust and optimize suction positions and forces. This feedback loop ensures reliable product removal by continuously evaluating and adjusting suction parameters based on actual product geometry.
Solution Approach 2:
The invention changes the suction force parameter at different suction positions along the transport path. By varying the suction force according to the calculated evaluation indices for each position, the system ensures adequate suction to prevent product catching while maintaining ease of control through automated parameter adjustment.
3Manufacturing precision
If multiple suction positions are evaluated with indices, then the suction state is optimized, but the calculation and control complexity increases
Solution Approach 1:
The control data creation device automatically performs the evaluation and optimization of suction states at multiple positions using the product shape data and pad arrangement information. The system serves itself by autonomously calculating evaluation indices and determining optimal suction parameters without requiring external intervention or complex manual configuration.
Solution Approach 2:
The invention uses the product shape data as a digital copy or model of the actual product to perform virtual evaluation of suction states at different positions. This allows precise determination of optimal suction forces without physical testing, reducing the need for complex experimental setups while maintaining high precision.

AI summary
A control data creation device (21) includes a specifying unit configured to change suction positions at which carrying-out arms (61a, 61b) suction a product P by moving the carrying-out arms (61a, 61b) on product data so as to specify an index for evaluating a suction state for each of the suction positions, and a layout setting unit (21c) configured to create control data in which the suction position is laid out to the product P based on each index specified for each of the suction positions.
