Description

Technical Field

[0001] The utility model relates to the technical field of garment processing equipment, in particular to a positioning device for a bag-opening machine with a wide application range. Background Art

[0002] Clothes are necessities of people's life. Pockets are usually provided on both clothes and trousers. Therefore, in the process of garment processing, there is usually a bag-opening process. In the prior art, a bag-opening machine is usually used to sew the bag mouth on the garment. However, the bag-opening position of the pocket must be opened at a fixed position. In the prior art, in order to ensure the accuracy of the bag-opening position, an infrared projector is usually used to project infrared rays onto the workbench, and then the pocket is placed at the corresponding position. The defects of this positioning device of the pocket machine are as follows: First, when the staff places the pocket parts and the garment pieces, the hands of the staff will block the infrared rays, thus affecting the placement efficiency and accuracy of the pocket parts and the garment pieces; Second, when the staff places the pocket parts and the garment pieces according to the position of the infrared rays, the pocket parts and the garment pieces are prone to sliding, thus affecting the placement efficiency and accuracy; Third, if the style of the garment to be processed changes, the relative positions of the garment pieces and the pocket parts will change. Therefore, it is necessary to reposition the infrared projector or replace the fixing device, which will reduce the processing efficiency and increase the processing cost. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a positioning device for a bag-opening machine with a wide application range, which can improve the processing efficiency, improve the accuracy of the bag-opening position of the pocket, and can adapt to different sizes of garments.

[0004] Technical solution of the utility model: A positioning device for a bag-opening machine with a wide range of applications, comprising an equipment base, a sewing machine connected to the equipment base, a positioning device connected to the equipment base, a material pressing device connected to the equipment base, and a controller. The positioning device includes a first positioning block slidably connected to the equipment base, a second positioning block slidably connected to the first positioning block, a third positioning block slidably connected to the equipment base, a fourth positioning block slidably connected to the third positioning block, a fifth positioning block slidably connected to the third positioning block, a fixed block fixedly connected to the first positioning block, a first hydraulic cylinder for driving the movement of the first positioning block, a second hydraulic cylinder for driving the movement of the second positioning block, a third hydraulic cylinder for driving the movement of the third positioning block, a fourth hydraulic cylinder for driving the movement of the fourth positioning block, and a fifth hydraulic cylinder for driving the movement of the fifth positioning block. The distance between the fourth positioning block and the fifth positioning block is adapted to the width of the pocket component to be processed, and the distance between the fixed block and the second positioning block is adapted to the width of the garment fabric piece to be processed. The movement directions of the first positioning block and the third positioning block are in the X-axis direction, and the movement directions of the second positioning block, the fourth positioning block, and the fifth positioning block are in the Y-axis direction. The material pressing device includes a workbench slidably connected to the equipment base, a connecting frame fixedly connected to the workbench, a material pressing plate slidably connected to the connecting frame, a sixth hydraulic cylinder for driving the movement of the workbench, and a seventh hydraulic cylinder for driving the movement of the material pressing plate. The movement direction of the workbench is in the Y-axis direction, and the movement direction of the material pressing plate is in the vertical direction. The sewing machine is located directly above the workbench. A fixed frame, a top rod slidably connected to the fixed frame, and an eighth hydraulic cylinder for driving the movement of the top rod are further provided on the equipment base. A limiting groove is provided on the material pressing plate, and the width of the limiting groove is greater than or equal to the diameter of the top rod. The movement direction of the top rod is in the vertical direction, and the top rod is located directly above the limiting groove. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the fifth hydraulic cylinder, the sixth hydraulic cylinder, the seventh hydraulic cylinder, and the eighth hydraulic cylinder respectively.

[0005] Adopting the above technical solution, first, the controller controls the first hydraulic cylinder and the third hydraulic cylinder to drive the first positioning block and the third positioning block to move along the X-axis direction respectively, so that the distances between the first positioning block and the second positioning block and the pressing plate are adapted to the relative positions between the pocket component to be processed and the garment fabric piece. Then, the second hydraulic cylinder, the fourth hydraulic cylinder and the fifth hydraulic cylinder drive the second positioning block, the fourth positioning block and the fifth positioning block to move along the Y-axis direction respectively, so that the distance between the fixed block and the second positioning block is adapted to the width of the garment fabric piece to be processed, and the distance between the fourth positioning block and the fifth positioning block is adapted to the width of the pocket component to be processed. Then, the pocket component to be processed is first placed between the fourth positioning block and the fifth positioning block, and the edge of the pocket component is pressed against the side of the third positioning block. Then, the garment fabric piece to be processed is placed between the fixed block and the second positioning block, and at the same time, the edge of the garment fabric piece is pressed against the side of the first positioning block. Then, the controller controls the seventh hydraulic cylinder to drive the pressing plate to move vertically downward, and the pressing plate presses the pocket component and the garment fabric piece between the workbench and the pressing plate. Then, the controller controls the sixth hydraulic cylinder to drive the workbench to move along the Y-axis direction, and at the same time, the sewing machine sews the position of the pocket. In this way, the bag opening step is completed. In addition, when the pocket component and the garment fabric piece are positioned, first, the controller controls the eighth hydraulic cylinder to drive the ejector rod to move vertically downward, so that a point of the relative position between the pocket component and the garment fabric piece is fixed. Then, the controller controls the seventh hydraulic cylinder to drive the pressing plate to move vertically downward, avoiding the air flow being brought up during the downward pressing of the pressing plate, which may change the relative position between the pocket component and the garment fabric piece, and further ensuring the accuracy of the feeding position. The advantages compared with the traditional positioning device are as follows: The relative relationship between the first positioning block, the second positioning block, the third positioning block, the fourth positioning block and the fifth positioning block can be adjusted according to the sizes of the pocket component to be processed, the garment fabric, and the different pocket installation positions, greatly improving the application range of the device. There is no need for multiple sets of fixing devices to meet the processing requirements of different styles. At the same time, compared with positioning by an infrared projector, the feeding efficiency and the accuracy of the feeding position can be improved.

[0006] Further setting of the present utility model: Feeding grooves are provided on the second positioning block, the fourth positioning block and the fifth positioning block. The distance between the bottom of the feeding groove and the upper surface of the equipment base is 0.5 cm. The opening direction of the feeding groove faces the direction of the workbench. The width of the feeding groove is greater than the sum of the thicknesses of the pocket component to be processed and the garment fabric piece.

[0007] With the above technical solution, since the second positioning block, the fourth positioning block, and the fifth positioning block are all provided with material passing grooves, when the pocket component and the garment piece are positioned, the sixth hydraulic cylinder drives the workbench to move in the direction of the sewing machine, and the pocket component and the garment piece will pass through the material passing grooves, avoiding phenomena such as wire drawing and wrinkles when the pocket component and the garment piece pass through the second positioning block, the fourth positioning block, or the fifth positioning block during sewing.

[0008] A further setting of the present utility model: A rubber pad is provided at the end of the ejector rod.

[0009] With the above technical solution, since a rubber pad is provided at the end of the ejector rod, the rubber pad has a high friction coefficient and flexibility, which can prevent relative sliding between the ejector rod and the garment piece, further improving the accuracy of the feeding position of the garment piece and the pocket component. At the same time, it can prevent the ejector rod from piercing or leaving imprints on the garment piece or the pocket component, affecting the quality of the garment to be processed. A further setting of the present utility model: A plurality of anti-slip lines evenly distributed on the rubber pad are provided on the rubber pad. The anti-slip lines are circular, and the thickness of the anti-slip lines is less than 0.2 cm.

[0010] With the above technical solution, since the rubber pad is provided with anti-slip lines, the friction between the rubber pad, the ejector rod, and the garment piece can be further improved, thereby preventing relative sliding between the ejector rod and the garment piece, further improving the accuracy of the feeding position of the garment piece and the pocket component. In addition, since the thickness of the anti-slip lines is less than 0.2 cm, the problem of wrinkles appearing on the garment piece when it is pressed can be reduced. Description of the Drawings

[0014] As shown Figure 1-2 , a positioning device for a bag-opening machine with a wide application range includes an equipment base 1, a sewing machine 2 connected to the equipment base 1, a positioning device 3 connected to the equipment base 1, a material pressing device 4 connected to the equipment base 1, and a controller 5. The positioning device 3 includes a first positioning block 6 slidably connected to the equipment base 1, a second positioning block 7 slidably connected to the first positioning block 6, a third positioning block 8 slidably connected to the equipment base 1, a fourth positioning block 9 slidably connected to the third positioning block 8, a fifth positioning block 10 slidably connected to the third positioning block 8, a fixed block 11 fixedly connected to the first positioning block 6, a first hydraulic cylinder 12 for driving the movement of the first positioning block 6, a second hydraulic cylinder 13 for driving the movement of the second positioning block 7, a third hydraulic cylinder 14 for driving the movement of the third positioning block 8, a fourth hydraulic cylinder 15 for driving the movement of the fourth positioning block 9, and a fifth hydraulic cylinder 16 for driving the movement of the fifth positioning block 10. The distance between the fourth positioning block 9 and the fifth positioning block 10 is adapted to the width of the pocket component to be processed. The distance between the fixed block 11 and the second positioning block 7 is adapted to the width of the garment fabric piece to be processed. The movement directions of the first positioning block 6 and the third positioning block 8 are in the X-axis direction, and the movement directions of the second positioning block 7, the fourth positioning block 9, and the fifth positioning block 10 are in the Y-axis direction. The material pressing device 4 includes a workbench 17 slidably connected to the equipment base 1, a connecting frame 18 fixedly connected to the workbench 17, a material pressing plate 19 slidably connected to the connecting frame 18, a sixth hydraulic cylinder 20 for driving the movement of the workbench 17, and a seventh hydraulic cylinder 21 for driving the movement of the material pressing plate 19. The movement direction of the workbench 17 is in the Y-axis direction, and the movement direction of the material pressing plate 19 is in the vertical direction. The sewing machine 2 is located directly above the workbench 17. The equipment base 1 is further provided with a fixed frame 22, a top rod 23 slidably connected to the fixed frame 22, and an eighth hydraulic cylinder 24 for driving the movement of the top rod 23. The material pressing plate 19 is provided with a limiting groove 25, the width of the limiting groove 25 is greater than or equal to the diameter of the top rod 23, the movement direction of the top rod 23 is in the vertical direction, and the top rod 23 is located directly above the limiting groove 25. The controller 5 is electrically connected to the first hydraulic cylinder 12, the second hydraulic cylinder 13, the third hydraulic cylinder 14, the fourth hydraulic cylinder 15, the fifth hydraulic cylinder 16, the sixth hydraulic cylinder 20, the seventh hydraulic cylinder 21, and the eighth hydraulic cylinder 24 respectively.

[0015] First, the controller 5 controls the first hydraulic cylinder 12 and the third hydraulic cylinder 14 to drive the first positioning block 6 and the third positioning block 8 to move along the X-axis direction respectively, so that the distances between the first positioning block 6 and the second positioning block 7 and the pressing plate 19 are adapted to the relative positions between the pocket component to be processed and the garment piece. Then, the second hydraulic cylinder 13, the fourth hydraulic cylinder 15 and the fifth hydraulic cylinder 16 drive the second positioning block 7, the fourth positioning block 9 and the fifth positioning block 10 to move along the Y-axis direction respectively, so that the distance between the fixed block 11 and the second positioning block 7 is adapted to the width of the garment piece to be processed, and the distance between the fourth positioning block 9 and the fifth positioning block 10 is adapted to the width of the pocket component to be processed. Then, the pocket component to be processed is first placed between the fourth positioning block 9 and the fifth positioning block 10, and the edge of the pocket component is pressed against the side of the third positioning block 8. Then, the garment piece to be processed is placed between the fixed block 11 and the second positioning block 7, and at the same time, the edge of the garment piece is pressed against the side of the first positioning block 6. Then, the controller 5 controls the seventh hydraulic cylinder 21 to drive the pressing plate 19 to move vertically downward, and the pressing plate 19 presses the pocket component and the garment piece between the workbench 17 and the pressing plate 19. Then, the controller 5 controls the sixth hydraulic cylinder 20 to drive the workbench 17 to move along the Y-axis direction, and at the same time, the sewing machine 2 sews the position of the pocket, thus completing the bag-opening step. In addition, when the pocket component and the garment piece are positioned, the controller 5 first controls the eighth hydraulic cylinder 24 to drive the ejector rod 23 to move vertically downward, so that a point of the relative position between the pocket component and the garment piece is fixed. Then, the controller 5 controls the seventh hydraulic cylinder 21 to drive the pressing plate 19 to move vertically downward, avoiding the air flow being brought up during the downward pressing of the pressing plate 19 and causing the relative position between the pocket component and the garment piece to change, further ensuring the accuracy of the feeding position. The advantages compared with the traditional positioning device 3 are as follows: The relative relationship between the first positioning block 6, the second positioning block 7, the third positioning block 8, the fourth positioning block 9 and the fifth positioning block 10 can be adjusted according to the sizes of the pocket component to be processed, the garment fabric and the different pocket installation positions, greatly improving the applicable range of the device. There is no need for multiple sets of fixing devices to meet the processing requirements of different styles. At the same time, compared with positioning by an infrared projector, the feeding efficiency and the accuracy of the feeding position can be improved. Overflow slots 26 are provided on the second positioning block 7, the fourth positioning block 9 and the fifth positioning block 10. The distance between the bottom of the overflow slot 26 and the upper surface of the equipment base 1 is 0.5 cm. The opening direction of the overflow slot 26 faces the direction of the workbench 17. The width of the overflow slot 26 is greater than the sum of the thicknesses of the pocket component to be processed and the garment piece.

[0016] Since the second positioning block 7, the fourth positioning block 9, and the fifth positioning block 10 are all provided with material passing grooves 26, when the pocket component and the garment piece are positioned, the sixth hydraulic cylinder 20 drives the workbench 17 to move in the direction of the sewing machine 2, and the pocket component and the garment piece will pass through the material passing grooves 26, avoiding phenomena such as wire drawing and wrinkles when the pocket component and the garment piece pass through the second positioning block 7, the fourth positioning block 9, or the fifth positioning block 10 during sewing.

[0017] A rubber pad 27 is provided at the end of the ejector rod 23.

[0018] Since a rubber pad 27 is provided at the end of the ejector rod 23, and the rubber pad 27 has a high friction coefficient and flexibility, it can prevent relative sliding between the ejector rod 23 and the garment piece, further improving the accuracy of the feeding positions of the garment piece and the pocket component. At the same time, it can prevent the ejector rod 23 from piercing or leaving imprints on the garment piece or the pocket component, affecting the quality of the garment to be processed.

[0019] A plurality of anti-slip lines 28 evenly distributed on the rubber pad 27 are provided on the rubber pad 27. The anti-slip lines 28 are circular, and the thickness of the anti-slip lines 28 is less than 0.2 cm.

[0020] Since the rubber pad 27 is provided with anti-slip lines 28, the friction between the rubber pad 27, the ejector rod 23, and the garment piece can be further increased, thereby preventing relative sliding between the ejector rod 23 and the garment piece and further improving the accuracy of the feeding positions of the garment piece and the pocket component. In addition, since the thickness of the anti-slip lines 28 is less than 0.2 cm, the problem of wrinkles appearing on the garment piece when pressed by the anti-slip lines 28 can be reduced.
