Description

Technical Field

[0001] The utility model relates to the technical field of computerized pattern sewing machines, and particularly relates to a computerized pattern sewing machine. Background Art

[0002] Trunks, bags and leather goods are widely used. In order to meet the needs of users, some patterns are usually sewn on the surface of trunks, bags and leather goods to improve the aesthetics of the products themselves. This process is completed with the help of a computerized pattern sewing machine. A computerized pattern sewing machine is a modern embroidery device that can automatically perform embroidery through a computer program. Compared with traditional manual embroidery, the computerized pattern sewing machine has the advantages of high production efficiency, high embroidery precision, and simple operation. Some computerized pattern sewing machines include an operating table, and a driving motor is connected to the operating table through an X-Y moving guide rail mechanism. When sewing patterns on the fabric of trunks, bags and leather goods, the fabric is placed below the sewing position, and then pressed down by a rectangular pressing frame to squeeze and fix the edge of the fabric, which inevitably causes relative sliding between the fabric and the operating table during the sewing process, affecting the pattern sewing effect of the device. After the fabric is fixed, the driving motor is used to drive the upper shaft to perform the needle pricking action, so as to sew patterns on the fabric of trunks, bags and leather goods. At the same time, the X-Y moving guide rail mechanism is used to adjust the position of the sewing position of the fabric of trunks, bags and leather goods. However, the structure of the rectangular pressing frame of the device is fixed, so that the device can only sew and fix patterns on the fabric of trunks, bags and leather goods within a certain size range, which needs to be improved.

The automatic material pressing mechanism 7 is cooperatively installed with the placing plate 6. The automatic material pressing mechanism 7 includes a fixed rod 71 and a camera 72. The fixed rod 71 is arranged on the upper side of the operating table 1. A camera 72 is provided at the lower left end of the fixed rod 71. The camera 72 is bidirectionally electrically connected to the PLC controller 2. The camera 72 is cooperatively installed with the placing plate 6. The automatic material pressing mechanism 7 further includes a fixed seat 73, a horizontal movement assembly 74, a third electro-hydraulic push rod 75 and a material pressing seat 76. The fixed seats 73 are evenly arranged on the upper side of the operating table 1. The upper ends of the fixed seats 73 are all provided with the third electro-hydraulic push rods 75 through the horizontal movement assembly 74.

The automatic material pressing mechanism 7 further includes pressure sensors 77. The pressure sensors 77 are all arranged on the lower sides of the material pressing seats 76. The pressure sensors 77 are bidirectionally electrically connected to the PLC controller 2. When using the device to perform pattern sewing on the leather fabric for cases and bags, first, spread the leather fabric for cases and bags on the middle of the placing plate 6. Subsequently, the PLC controller 2 starts the camera 72. The camera 72 collects the images of the placing plate 6 and the leather fabric for cases and bags placed above it and transmits them to the PLC controller 2 in the form of electrical signals. The PLC controller 2, according to the image recognition technology, determines the distribution of the leather fabric for cases and bags on the placing plate 6 by using the color difference between the two, and then determines the positions of the four corner points that need to be fixed during the pattern sewing process of the leather fabric for cases and bags. Subsequently, the PLC controller 2 controls the corresponding first electro-hydraulic push rod 741 according to the horizontal lateral distance and horizontal longitudinal distance between the initial material pressing seat 76 and the central part of the placing plate 6, so that its telescopic end indirectly drives the material pressing seat 76 to move horizontally laterally, and controls the second electro-hydraulic push rod 743 so that its telescopic end indirectly drives the material pressing seat 76 to move horizontally longitudinally, so that the material pressing seat 76 is horizontally translated to the corresponding material pressing point of the leather fabric for cases and bags.

The PLC controller 2 stops the telescopic end movement stroke of the electro-hydraulic push rod three 75 in a timely manner according to the measured pressure value, avoiding excessive pressure applied by the pressure seat 76 through the electro-hydraulic push rod three 75, which may cause extrusion damage to the case leather and luggage fabric. This device can automatically extrude and fix the corner parts of case leather and luggage fabrics of different sizes by using image recognition technology and driving elements, with convenient operation and effectively improving the applicable range of the device for pattern sewing of case leather and luggage fabrics;

[0024] Among them: it also includes a PLC controller 2. The PLC controller 2 is arranged at the left end of the operation table 1.

[0025] The working principle of a computerized pattern sewing machine provided by the utility model is as follows: The universal wheels 9 facilitate the pushing of the device to the designated position without manual lifting. When using the device to sew patterns on the fabric of leather cases and bags, first, spread the fabric of leather cases and bags on the middle of the placement board 6. Then, the PLC controller 2 starts the camera 72. The camera 72 collects the images of the placement board 6 and the fabric of leather cases and bags placed above it and transmits them to the PLC controller 2 in the form of electrical signals. According to the image recognition technology, the PLC controller 2 determines the distribution of the fabric of leather cases and bags on the placement board 6 by using the color difference between the two, and then determines the positions of the four corner points that need to be fixed during the pattern sewing process of the fabric of leather cases and bags. Subsequently, based on the horizontal lateral distance and the horizontal longitudinal distance between the initial pressure seat 76 and the central part of the placement board 6, the PLC controller 2 controls the corresponding electro-hydraulic push rod 741 so that its telescopic end indirectly drives the pressure seat 76 to move horizontally laterally, and controls the electro-hydraulic push rod 743 so that its telescopic end indirectly drives the pressure seat 76 to move horizontally longitudinally, so that the pressure seat 76 horizontally translates to the corresponding pressure point of the fabric of leather cases and bags. Then, the PLC controller 2 starts the electro-hydraulic push rod 75 so that its telescopic end drives the pressure seat 76 to move vertically downward, so as to automatically press and fix the fabric of leather cases and bags to the placement board 6 according to the actual situation. During the process of the pressure seat 76 moving vertically downward, the PLC controller 2 starts the pressure sensor 77. When the pressure seat 76 applies pressure to the upper side of the fabric of leather cases and bags, the pressure sensor 77 detects the pressure value and transmits it to the PLC controller 2 in the form of an electrical signal. The PLC controller 2 stops the moving stroke of the telescopic end of the electro-hydraulic push rod 75 in a timely manner according to the measured pressure value, so as to avoid excessive pressure applied by the pressure seat 76 through the electro-hydraulic push rod 75, which may cause extrusion damage to the fabric of leather cases and bags. After fixing the fabric of leather cases and bags, the PLC controller 2 starts the electric sewing head 5 to perform pattern sewing processing on the fabric of leather cases and bags. The PLC controller 2 controls the moving end of the linear motor 3 to adjust the horizontal position of the pattern sewing part of the electric sewing head 5, and the PLC controller 2 controls the moving end of the linear motor 4 to adjust the vertical position of the pattern sewing part of the electric sewing head 5.
