Suction Position Layout for Stable Product Carry-Out
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling loader devices fail to adequately consider the suction state when removing products from workpieces, leading to slanted or deflected products that can get caught in residual workpiece material.
Innovation Solution
A control data creation device that adjusts suction positions on carrying-out arms using suction pads to evaluate and optimize the suction state, ensuring stable product removal by specifying a suction gravity center and creating control data for appropriate suction positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suction control is used without considering suction state, then the control system is simple, but the product becomes slanted or deflected and gets caught in residual workpiece material
Solution Approach 1:
The control data creation device performs preliminary evaluation of suction positions before actual product removal. It calculates suction forces at multiple candidate positions and determines the optimal suction position in advance, preventing product deflection and catching issues during actual operation.
Solution Approach 2:
The system evaluates suction forces at each candidate position and uses this feedback to determine the optimal suction position. The control data creation device compares suction forces and selects the position that provides the most stable product removal, creating a closed-loop control system.
2Reliability
If suction position is not optimized, then the carrying-out operation is simple, but the product is caught in residual workpiece material
Solution Approach 1:
The control data creation device automatically evaluates multiple suction positions and selects the optimal one without requiring manual intervention. The system self-determines the best suction position by calculating and comparing suction forces, making the process autonomous and improving reliability.
Solution Approach 2:
The system changes the suction position parameter by evaluating multiple candidate positions and selecting the optimal one based on suction force calculations. This parameter optimization ensures stable product removal while the automation maintains ease of manufacture.
3Measurement precision
If multiple suction positions are evaluated, then the suction state is optimized, but the calculation time increases
Solution Approach 1:
The system evaluates suction forces at multiple candidate positions (excessive action) to ensure optimal suction state, but only selects the single best position for actual use. This partial application of extensive evaluation maintains precision while managing time loss by not implementing all evaluated positions.

AI summary
A control data creation device includes a specifying unit configured to change suction positions at which carrying-out arms suction a product P by moving the carrying-out arms 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 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.
