Solution Overview
Problem
Conventional sewing devices require multiple machines and significant space to perform a variety of sewing patterns, leading to increased costs and inefficiencies in both two-dimensional and three-dimensional sewing tasks.
Innovation Solution
A dual-arm robot system integrated with a sewing machine, camera, image processing, and command transmission, allowing for precise alignment and movement control of sewing arms to execute different sewing patterns, including fixed position, fixed length, corrected, and jig-based sewing, using program control and image processing for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple specialized sewing devices are used to carry out different sewing patterns, then sewing precision for specific patterns is improved, but device complexity and installation space increase
Solution Approach 1:
The sewing device incorporates multiple sewing mechanisms (first sewing mechanism for first sewing pattern, second sewing mechanism for second sewing pattern) within a single integrated system. The program control means coordinates these mechanisms to execute different sewing patterns as needed, allowing one device to perform multiple functions that previously required separate specialized machines.
2Manufacturing precision
If multiple specialized sewing devices are used to carry out different sewing patterns, then sewing precision for specific patterns is improved, but installation space increases
Solution Approach 1:
The invention merges multiple specialized sewing devices into a single integrated sewing device. The first sewing mechanism and second sewing mechanism are combined within one device structure, sharing common components such as the program control means, camera, and support structure, thereby reducing the total installation space required compared to having separate dedicated machines for each sewing pattern.
3Manufacturing precision
If multiple specialized sewing devices are used, then specific sewing tasks can be performed accurately, but equipment cost increases
Solution Approach 1:
By designing a universal sewing device that can execute multiple sewing patterns through program control, the invention eliminates the need to purchase and maintain multiple separate specialized machines. The program control means stores and executes different sewing patterns (first sewing pattern, second sewing pattern), allowing the same hardware to deliver specialized sewing accuracy for different tasks without requiring duplicate equipment investments.
4Adaptability or versatility
If manual sewing work is performed by skilled workers, then various sewing patterns can be achieved with flexibility, but productivity decreases
Solution Approach 1:
The invention replaces manual sewing operations with an automated sewing device controlled by a program control means. The camera captures sewing portion information, the image processing portion analyzes this data, and the program control means automatically selects and executes the appropriate sewing pattern from stored programs. This automation maintains the versatility of handling different sewing patterns while dramatically increasing productivity by eliminating manual labor constraints.
5Productivity
If automated sewing device is used, then productivity is improved, but adaptability to different sewing patterns decreases
Solution Approach 1:
The sewing device incorporates dynamic adaptability through its control system. The program control means can selectively activate different sewing mechanisms (first sewing mechanism, second sewing mechanism) based on the specific sewing task requirements. The camera and image processing portion dynamically adjust to capture and analyze different sewing portion information, allowing the automated system to adapt its operation to various sewing patterns while maintaining high productivity.

AI summary
The invention provides a sewing device which can precisely and evenly carry out a great variety of sewing works further with a good productivity. The sewing device has a sewing machine (2), and a dual-arm robot (7) having a first arm (5) and a second arm (6) which can operate an object to be sewn (4) supplied to a sewing motion portion (3) of the sewing machine. The duel-arm robot is provided with a camera which can image the sewing motion portion. Further, the sewing device is provided with an image processing portion which processes an image information acquired by the camera, and a command transmitting portion which transmits commands to an arm control portion controlling the first arm and the second arm on the basis of a processing result of the image processing portion.
