Sewing System Base for Robot Arm Positional Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sewing systems with a robot arm, positional deviations occur between the sewing machine and the robot arm when the system is moved or rearranged, necessitating repeated teaching operations to set the target positions accurately.
Innovation Solution
The sewing system fixes the sewing machine and robot arm to a base, using a clamp jig held by the robot arm and a conveyor device to maintain the relative positional relationship, reducing the need for repeated teaching operations by keeping the target position set once the system is moved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sewing machine and robot arm are independently provided, then the system has flexibility in arrangement, but positional deviation occurs when the system is moved or rearranged
Solution Approach 1:
The sewing machine and robot arm are merged into a single integrated unit by fixing both to a common base. This ensures that when the system is moved or rearranged, the relative positional relationship between the sewing machine and robot arm remains constant, eliminating the need for repeated teaching operations while maintaining flexibility through the movable base with wheels.
2Loss of time
If the sewing machine and robot arm are fixedly supported at fixed positions, then teaching operation is reduced, but the system becomes harder to relocate
Solution Approach 1:
Both the sewing machine and robot arm are fixedly supported to the same base, creating a relocatable integrated system. The base itself is equipped with wheels, allowing the entire system to be easily moved to different locations while maintaining the fixed relative positions of its components, thus reducing teaching operation time while preserving relocatability.
Solution Approach 2:
The base serves as an intermediary platform that provides both stability for fixed positioning and mobility through integrated wheels. This mediator allows the system to achieve both contradictory requirements: fixed relative positioning for reduced teaching operations and ease of relocation for adaptability.

AI summary
According to the sewing system of the present embodiment, the sewing machine and the robot arm are fixedly supported at the fixed positions by the base. Therefore, when a target position of the robot arm for the sewing operation is set once, a relative positional relation between the robot arm and the sewing machine is kept by the base even though the sewing system is entirely moved. Therefore, it is not necessary to again perform a setting operation of the target position for the sewing operation, so that the burdens on the teaching operation and the other setting operations are reduced.
