Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewing systems face challenges in maintaining productivity due to inefficiencies in feeding cloth to sewing machines, leading to potential errors and defects in sewn products, particularly in aligning and stitching clothing components like T-shirts.
Innovation Solution
A sewing system incorporating a cloth conveyor with a robot and conveying member that uses suction surfaces to hold and adjust the position of cloth components, along with a cloth position adjustment device and fine movement mechanisms, ensures precise alignment and feeding of cloth parts to sewing machines, enabling accurate stitching and preventing defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cloth feeding methods are used, then the sewing system can operate, but productivity deteriorates due to inefficiencies in feeding cloth
Solution Approach 1:
The patent replaces conventional mechanical cloth feeding mechanisms with a robot system that uses suction surfaces to hold and convey cloth components. This substitution enables more precise and efficient cloth handling, directly improving productivity by eliminating the time losses associated with traditional feeding methods
Solution Approach 2:
The patent employs suction surfaces that utilize pneumatic principles to hold and transport cloth components. The robot system uses controlled suction to grasp and move cloth accurately, replacing mechanical feeding methods and significantly reducing the time required for cloth feeding operations
2Manufacturing precision
If conventional cloth feeding methods are used, then the system can function, but manufacturing precision deteriorates due to alignment errors
Solution Approach 1:
The patent replaces imprecise mechanical feeding mechanisms with a robot system equipped with suction surfaces. This substitution provides superior control over cloth positioning and alignment, ensuring that cloth components are accurately aligned before stitching, thereby improving manufacturing precision and stitching reliability
Solution Approach 2:
The patent incorporates a detector that acquires images of cloth components and provides feedback to the control unit. The control unit processes this image data to determine precise positions and adjusts the robot's cloth handling accordingly, ensuring accurate alignment and positioning for reliable stitching operations
3Manufacturing precision
If conventional feeding methods are used, then operation is simple, but device complexity increases to achieve precise alignment
Solution Approach 1:
The patent employs a robot system that performs multiple functions: it holds cloth with suction surfaces, conveys cloth to the sewing machine, positions cloth components, and adjusts alignment. This multi-functional approach achieves precise alignment while consolidating what would otherwise require multiple separate devices into a single integrated system
Solution Approach 2:
The patent introduces a control unit as an intermediary that coordinates between the detector, robot system, and sewing machine. The control unit processes image data from the detector and translates it into precise robot movements, serving as a smart mediator that enables precise alignment through intelligent control rather than mechanical complexity

AI summary
A sewing system which includes a detector for detecting an edge of a cloth installed on an installation table, a cloth conveyor for conveying the cloth from the installation table to a sewing machine, and a controller, wherein the cloth conveyor includes a holding member that holds the cloth, and the controller includes a holding position decision portion that determines a holding position of the cloth based on detection data of the detector, and a conveyance control portion that controls the cloth conveyor such that the holding member holds the holding position. In the sewing system according to the above, it is possible to prevent deterioration in productivity of sewn products.
