Description

TECHNICAL FIELD

[0001] The present application belongs to the field of producing and manufacturing of jackets, and particularly relates to a continuous sewing assembly line processing device for producing a jacket template. BACKGROUND

[0002] In the continuous sewing assembly line processing for producing a jacket template, the traditional device has many technical defects, which are as follows:

[0003] Low positioning and conveying precision of the template: the traditional assembly line uses fixed guide rails to convey the template, and only uses a single direction limiting structure for positioning, which cannot dynamically adjust according to different sizes and shapes of the jacket template. When the template has a slight deviation during the conveying process, there is no real-time correction mechanism, which leads to a large deviation between the needle position and the preset stitch of the template in the subsequent sewing process, and finally causes the problems of sewing misalignment and uneven stitches, which seriously affects the waterproof performance and appearance quality of the jacket, and requires manual correction, increasing the production cost and working hours.

[0004] Sewing parameters cannot be self-adaptively adjusted: the parameters such as stitch density and presser foot pressure of the traditional sewing device need to be manually preset, and are fixed throughout the process. Due to the differences in the thickness and material (such as waterproof coated cloth and fleece cloth) of the jacket fabric, the fixed parameters cannot adapt to the characteristics of different fabrics - for thick fabric, fixed stitch density will cause the stitches to be too sparse and the seams to be not firm; for thin fabric, fixed presser foot pressure will cause the fabric to be crushed and damaged, and the parameters also cannot be adjusted according to the needs of different sewing areas (such as cuffs and collars) on the template, leading to poor consistency of the sewing quality.

[0005] Quality monitoring is lagging and has no closed-loop feedback: the quality detection of the traditional assembly line is mostly manual sampling inspection after all the sewing processes are completed, which cannot obtain quality data in real time during the sewing process. If quality problems are detected, a large number of unqualified products have been produced, and the problem source (such as positioning deviation and improper parameters) cannot be traced, and the parameters cannot be corrected in time in the positioning and conveying and sewing processes of the previous sequence, which leads to a high unqualified rate and difficult improvement of production efficiency, and the subjectivity of manual detection is strong, and the detection result has a large error;

[0064] Working principle and usage process of this invention:

[0065] Feeding and Positioning Stage: The template for the jacket is placed on the conveyor belt 23 of the closed-loop conveyor unit 2. The first control unit 8 starts the conveyor drive motor 24, and the drive roller 21 drives the conveyor belt 23 to rotate. The template is conveyed to the sewing area along with the belt. When the template reaches the first adjustable positioning component 3, the first control unit 8 controls the positioning drive component 34 to move the lateral adjustment component 32 and the longitudinal adjustment component 33 according to the preset template size data. The template is initially positioned laterally and longitudinally. At the same time, the tension adjustment cylinder 26 adjusts the position of the tension roller 25 under the control of the first control unit 8 to maintain the constant tension of the conveyor belt 23 and prevent the template from shifting. When the template continues to be conveyed to the second adjustable positioning component 3, a second positioning calibration is performed to ensure that the relative position deviation between the template and the sewing execution unit 5 is ≤ ±0.1 mm.

[0066] Feature acquisition and parameter calculation stage: After the template is positioned, it enters the working range of the intelligent adaptive sewing parameter module. The image acquisition camera 41 of the template feature acquisition unit 4 captures the template image and obtains the template outline and sewing area position data. The thickness sensor 42 contacts the template fabric and collects the fabric thickness.

If a thread breakage is detected, a signal is immediately sent to the second control unit 9. The second control unit 9 controls the sewing machine head 51 to stop. The machine is restarted after the sewing thread is manually replaced, ensuring that the sewing process is continuous and stable.

[0068] Quality Inspection and Feedback Correction Stage: The sewn template enters the inspection range of the full-process quality closed-loop feedback module along the conveyor belt 23. The appearance inspection camera 62 of the quality inspection unit 6 captures images of the sewing stitches, and the stitch deviation value is calculated through image recognition algorithms. Tensile sensor 61 clamps the template joint to detect the tensile strength of the joint. At the same time, the number of thread defects was counted.
