Description

Technical Field

[0001] This invention relates to the field of bag opening machine technology, and more specifically to a mobile bag opening machine. Background Technology

[0002] A pocket opening machine is a professional sewing device used to cut and sew pocket openings on garments. Its main body is a large flat platform equipped with a servo drive system, a laser cutting system, a slitting device, and a sewing machine head. The servo drive system precisely moves the fabric clamping mechanism on the platform. The laser cutting system achieves non-contact cutting of the fabric, resulting in clean, burr-free cuts. The slitting device separates the laser-cut fabric into the shape of the pocket opening. Finally, the sewing machine head sews the opening onto the garment, thus shaping the pocket. The slitting device is typically fixedly installed on the pocket opening machine. On the large flatbed of the machine, directly below the laser cutting system, the servo drive system moves the fabric to the position of the slitting device. The slitting device then fixes the fabric, which is then cut by the laser cutting system. After cutting, the slitting device separates the two sides of the opening in the fabric and folds the fabric at the opening. Then, in conjunction with the servo drive system, the template is moved so that the cut fabric is sewn by the sewing machine head to form a fabric with pockets. This process is highly automated, has good slitting stability, and produces consistently high-quality fabric with pockets.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: the existing slitting device is fixedly installed on a large flat plate. When in use, all steps can only be performed in a fixed position. Therefore, after laser cutting, it is necessary to wait for the slitting device to separate the fabric before the servo drive system can move the fabric to the sewing machine head for sewing. This takes a long time and affects the processing speed. Summary of the Invention

[0028] A further improvement is that the rotating gripping device includes a fixed frame whose bottom is fixedly connected to the top surface of the moving plate and a rotating column that penetrates and is movably engaged with the fixed frame. The bottom surface of the rotating column is provided with a connecting rod that is movably engaged with the end of the rotating cylinder.

[0033] After adopting the above technical solution, the beneficial effects of the present invention are as follows: In the process of using this invention, the fabric is placed on the slitting device. The top of the slitting device can move laterally along the transverse track, and it can also move back and forth via the forward moving device. The first and second transverse pulling cylinders of the slitting device body, as well as the first and second fabric pulling frames, are all mounted on a tray. Thus, during the movement of the slitting device, the first and second transverse pulling cylinders can be driven synchronously to move the first and second fabric pulling frames along the lower surfaces of the first and second placement plates. After the fabric is laser-cut, the slitting frame first descends to open the cut opening in the fabric. Then, the first and second fabric pulling frames can be used to pull open the cut position of the fabric, thereby forming a pocket opening. The step of opening the pocket can be performed simultaneously during the movement process, eliminating the need to move the fabric to a fixed position to open the pocket before proceeding to the next movement step, making the fabric pocket processing speed faster and the processing efficiency higher.

[0034] After the fabric bag is opened, the present invention uses a fabric lifting device located on one side of the separating device to fix the bag fabric placed on the template. During the opening process, the push-pull cylinder of the fabric lifting device is in the extended state, so that the fabric support plate does not directly contact the fabric. After the opening is completed, the push-pull cylinder is pulled back to retract and move the fabric support plate, which is then inserted under the template with the bag fabric for lifting. Together with the tray of the separating device, the bag fabric is clamped and fixed. Thus, when the template of the bag fabric is removed, the bag fabric is clamped, fixed and lifted, preventing the bag fabric from being pulled by the template and becoming skewed. At the same time, compared with the existing top column fixing device, the cover of the fabric support plate has a larger coverage area, which can accommodate smaller bags and has better adaptability.

[0035] This invention, after making an opening and overlapping the cloth bag with the opened fabric, allows the template for placing the bag fabric to be removed using a gripping device. During the gripping process, a rotating motor, in conjunction with a screw, causes a moving plate to move laterally on a support. Meanwhile, a rotating cylinder, in conjunction with a connecting rod, drives a rotating column to rotate, causing the placement tray loaded on the rotating column to rotate synchronously. The gripping device, along with hooks and gripping hooks that can be opened and closed by the gripping cylinder, grips the columnar protrusions on the template. The rotation then quickly separates the template from the separating device. Compared to traditional gripping devices that use servo mechanisms to drive lateral movement, this method of separating the template by rotation results in faster separation speeds, eliminates the need for complex servo transmission mechanisms, and offers a simpler structure, easier operation, and more convenient maintenance.

A first placement plate 423 and a second placement plate 422 are detachably disposed on the body 42 of the slitting device by bolts. A gap groove is formed between the first placement plate 423 and the second placement plate 422. The tray 4 The tray 421 is equipped with a first horizontal pull cylinder 429. At the end of the first horizontal pull cylinder 429 is a first fabric-pulling frame 427 located below the first placement plate 423 and slidably connected to the upper surface of the tray 421 at both ends.

At the end of the second horizontal pull cylinder 428 is a second fabric-pulling frame 432 located below the second placement plate 422 and slidably connected to the upper surface of the tray 421 at both ends. The second fabric-pulling frame 432 has the same structure as the first fabric-pulling frame 427. The first fabric-pulling frame 427 includes a fabric-pulling frame body 81 and a rising plate 82 integrally formed on both sides of the fabric-pulling frame body 81 and extending upwards, with longitudinally extending through slots.

A crossbar 34 is provided between two extension blocks 32. Two symmetrically distributed pressing devices are slidably mounted on the crossbar 34. Each pressing device includes a sliding plate 33 slidably mounted on the crossbar 34 and a pressing plate 35 detachably mounted on the side of the sliding plate 33 and extending downward. A fabric lifting device is also provided on one side of the separating device body 42, extending to the lower front side of the separating device body 42. The fabric lifting device includes a push-pull cylinder 45 fixedly connected to one side of the separating device body 42 and a push-pull cylinder 45 located at the end of the push-pull cylinder 45 and below the separating device body 42. The support plate 430, the processing table 2 is also provided with a transverse sliding slot 22, and the base 1 is provided with a gripping device 6 whose top can move laterally along the transverse sliding slot 22. The gripping device 6 includes a bracket 61 fixedly installed in the base 1 and a rotating motor 66 installed on the end of the bracket 61. The rotating shaft of the rotating motor 66 is connected to a screw 65 whose end is movably engaged with the inner wall of the bracket 61. The bracket 61 is also slidably provided with a moving plate 64 whose bottom is engaged with the outer wall of the screw 65. The upper surface of the moving plate 64 is provided with a transverse extension block 68. A rotating cylinder 69 is movably engaged on the transverse extension block 68. The moving plate 64 is also fixedly installed with a rotating gripping device 67. The rotating gripping device 67 includes a fixed frame 672 whose bottom is fixedly connected to the top surface of the moving plate 64 and a penetrating... Furthermore, a rotating column 678 is movably engaged on a fixed frame 672. The bottom surface of the rotating column 678 has a connecting rod 671 that movably engages with the end of a rotating cylinder 69. A placement tray 673 is located on the top surface of the rotating column 678. A template fixing device 676 is located on one side edge of the placement tray 673. The template fixing device 676 includes a gripping tray 71 and a hook 711 integrally formed on one side edge of the gripping tray 71. A gripping cylinder 72 is located on the gripping tray 71. A movable locking block 73 with a penetrating groove is located at the end of the gripping cylinder 72. A gripping hook 74, whose middle section movably engages with the gripping tray 71, is located on the gripping tray 71. One end of the gripping hook 74 is slidably connected to the inner wall of the penetrating groove of the movable locking block 73. During use, when forming a pocket... The fabric is placed on the slitting device 4. After the fabric is placed, it needs to be fixed by the fabric pressing device 425. The rear plate front cylinder 426 on the fabric pressing device 425 can control the overall height of the fabric pressing device 425, thereby controlling the position of the lifting plate 13. After the fabric is loaded, the fabric pressing cylinder 16 can drive the fabric pressing frame 15 to descend, so that the fabric pressing frame 15 presses on the fabric, thereby achieving the effect of fixing the fabric. The top of the slitting device 4 can move laterally along the transverse track 51 instead of being fixedly mounted on the processing table 2. The first transverse pull cylinder 429 and the second transverse pull cylinder 428, as well as the first fabric pulling frame 427 and the second fabric pulling frame 432 of the slitting device body 42 on the slitting device 4 are all mounted on the tray 421.The fabric slitting device 427 and 432 can move along with the tray 421. During the movement of the slitting device 4, the first horizontal pull cylinder 429 and the second horizontal pull cylinder 428 can be driven simultaneously to move the first fabric slitting frame 427 and the second fabric slitting frame 432 along the lower surfaces of the first and second placement plates 423 and 422. When passing the laser opening 21, the laser emitted by the laser emitter 60 can be emitted through the laser opening 21 to cut the fabric, creating an opening. After the fabric is laser-cut, the slitting frame 44 descends, causing the pressure plate 35 of the slitting frame 44 to move downwards, separating the cut fabric and opening the cut opening. Subsequently, the first horizontal pull cylinder 429, in conjunction with the second horizontal pull cylinder 428, can move the first fabric slitting frame 427 and the second fabric slitting frame 432, thereby causing the fabric slitting frame body 81 to slide along the sliding rod 83 on the rising plate 82 and the tray 421. Under the guiding action, the first fabric spreading frame 427 and the second fabric spreading frame 432 are brought close to the opening of the fabric. When they move to the position of the gap formed by the first placement plate 423 and the second placement plate 422, the fabric spreading grid 84 is no longer obstructed by the first placement plate 423 and the second placement plate 422, and thus rises and inserts into the opening of the fabric. Subsequently, the first horizontal pulling cylinder 429 and the second horizontal pulling cylinder 428 are pulled back, so that the fabric spreading grid 84 of the first fabric spreading frame 427 and the second fabric spreading frame 432 can open the cut position of the fabric, thereby forming the pocket opening. The above structure is integrated on the tray 421, rather than being fixed on the processing table 2. Therefore, the step of opening the pocket can be performed simultaneously during the moving step of the slitting device 4, without having to move the fabric to a fixed position to open the pocket first, then open the pocket, and then proceed to the next moving step, making the processing speed of the fabric pocket faster and the processing efficiency higher. Simultaneously, during the bag opening process, a bag fabric template needs to be placed at the starting position of the slitting device 4, and the bag fabric is loaded onto the template. Then, the fabric with the pocket opening moves to the position of the bag fabric template as the slitting device 4 moves. During the opening process of the slitting device 4, the push-pull cylinder 45 of the fabric lifting device is in an extended state, preventing the fabric support plate 430 from directly contacting the fabric. After the opening is completed and the slitting device 4 moves to the position of the bag fabric template, the push-pull cylinder 45 is pulled back, causing it to retract and move the fabric support plate 430. The fabric support plate 430 is then inserted under the template containing the bag fabric for lifting, working in conjunction with the tray 421 of the separating device body 42 to hold the bag... The fabric is clamped and fixed, so that when the template of the bag fabric is pulled away by the gripping device 6, the bag fabric can be clamped, fixed and lifted, so that the bag fabric will not be pulled by the template and become skewed. At the same time, compared with the existing top column fixing device, the cover plate 430 has a larger coverage area, which can accommodate smaller bag fabrics and has better adaptability. Then, the sewing template of the sewing machine head can be fed in by the gripping device 6 and the sewing template is inserted under the bag fabric and the opening fabric. At this time, the bag fabric and the opening fabric can be moved to the position of the sewing machine head 3 by the piece separating device 4 for sewing, thereby sewing and fixing the bag fabric and the opening fabric into shape, thus forming a finished fabric product with a pocket. Simultaneously, after opening the bag and overlapping it with the opened fabric, the template for placing the bag can be removed using the gripping device 6. During the gripping process, the moving plate 64 is moved laterally on the support by rotating the motor 66 in conjunction with the screw 65, while the rotating column 678 is rotated by the rotating cylinder 69 in conjunction with the connecting rod 671, thereby causing the placement tray 673 loaded on the rotating column 678 to rotate synchronously. This, combined with the hook 711 on the gripping device 6 and the gripping hook 74 which can be controlled to open and close by the gripping cylinder 72, allows the gripping cylinder to... When 72 extends, the inner end of the gripping hook 74 is pushed outward under the action of the moving block 73, which in turn causes its outer end to retract. At this time, it can work with the hook 711 to grip the columnar protrusion on the template. The thrust generated by the rotary cylinder 69 causes the template fixing device 676 to rotate, thereby quickly separating the template from the splitting device 4. Compared with the traditional servo mechanism driven transverse device, separating the template by rotation makes the separation speed faster, and there is no need to set up a complex servo transmission mechanism. The structure is simpler, the operation is easier, and the maintenance is more convenient. A forward moving device is also provided between the top surface of the slitting device 4 and the transverse track 51. The forward moving device includes a transverse connecting plate 52 that can be slidably set on the transverse track 51. The bottom surface of the transverse connecting plate 52 is provided with a forward moving track on which the slitting device 4 can slide. The rear side of the transverse connecting plate 52 is also provided with a forward pushing cylinder 53 whose end is connected to the slitting device 4. This is beneficial to enable the slitting device 4 to move back and forth by cooperating with the forward moving track through the forward pushing cylinder 53, thereby enabling it to obtain a larger range of movement on the processing table 2, thereby improving its flexibility of use. The rear panel 41 is also provided with a rear panel lifting device. The rear panel lifting device includes a rear panel rail 47 fixedly installed on the rear side of the rear panel 41 and a rear panel cylinder 48 fixedly installed on the rear side of the rear panel 41. The lower end of the rear panel cylinder 48 is provided with a thrust block 46, which facilitates the rear panel 41 to rise and fall through the rear panel cylinder 48 of the rear panel lifting device. In this way, when the bag cloth is loaded, the rear panel 41 can be lifted, so that the bag cloth will not be pushed by the slitting device body 42 and become skewed, making the processing more precise. The first placement plate 423 and the second placement plate 422 are both integrally formed with sieve teeth 431 on the corresponding edge of the interval groove. This is beneficial for the sieve teeth 431 to cooperate with the fabric grid 84 so that the opening of the fabric can be pulled more smoothly, thereby improving the effect of the fabric grid fixing 84 in opening the opening of the fabric. The upper surface of the tray 421 is also provided with trapezoidal middle lifting blocks 433 at the corresponding positions at both ends of the interval groove. This is beneficial for the first fabric pulling frame 427 and the second fabric pulling frame 432 to be lifted when they move to this position, so that the fabric pulling grid 84 can be inserted upward into the opening position of the fabric better and deeper, making the fabric opening more stable. The upper surface of the tray 421 is also provided with a rear lifting block 434 with a guide ramp, which is beneficial to the tray 421 and the rear plate 41 being lowered to lift it up and guide it onto the rear lifting block 434 when the first fabric rack 427 is retracted, so that it can be better fixed and prevent it from bulging downwards and affecting the placement of the bag fabric. The lifting plate 13 has a lifting cylinder 11 that is movably engaged on the front. The bottom end of the lifting cylinder 11 is movably engaged with the upper surface of the lower pressing plate 12. This allows the entire lower pressing plate 12 and the fabric pressing frame 15 to be lifted obliquely by retracting the lifting cylinder 11 when not in use. This provides more operating space when putting in fabric, preventing the operation space from being too small when loading large pieces of fabric, which would affect the accuracy of placement. It also makes it easier to put in fabric by expanding the operating space. The side edge of the pressing plate 12 is also provided with a pressing frame adjusting block 14 for adjusting the front and rear position of the pressing frame 15. The pressing frame adjusting block 14 is locked with a fastening screw with a handle, which makes it easy to adjust the pressing frame adjusting block 14 by loosening the fastening screw, thereby controlling the front and rear position of the pressing frame 15, so that the pressing frame 15 can be adapted to various fabrics of different sizes. The pressure plate 12 is also equipped with a buffer spring 17 whose bottom is attached to the pressure frame 15. This helps to absorb the reverse force after the pressure frame 15 descends rapidly, thereby preventing the pressure frame 15 from rebounding and bouncing, which would affect the pressure effect. The bottom surface of the lowering plate 446 is also provided with a positioning rod 449 that penetrates the lowering plate 446. The bottom end of the positioning rod 449 is fixedly connected to the top surface of the opening pressure frame 448, which helps to make the lifting trajectory of the opening pressure frame 448 straighter and avoids tilting when the second push cylinder 447 pushes the opening pressure frame 448 down. The sliding plate 33 has an integrally formed threaded hole perpendicular to the crossbar 34. A fastener 36 is engaged in the threaded hole. The fastener 36 is a stud 362. After the sliding plate 33 is installed, the end of the fastener 36 can be locked against the crossbar 34 to generate frictional resistance, thereby preventing the sliding plate 33 from sliding on the crossbar 34. This ensures the distance between the two sliding plates 33 and controls the size of the pressing opening. At the same time, when it is necessary to adjust the distance between the two sliding plates 33, the fastener 36 can be unscrewed so that its end is no longer pressed against the crossbar 34, and the position of the sliding plate 33 can be slid and adjusted, making it simpler and more convenient to adjust the distance between the pressure plates 35. A rubber block 363 is provided on the end of the stud 362 near the crossbar 34, which helps to increase the frictional resistance between the end of the stud 362 and the crossbar 34 after it is screwed in, and further prevents the sliding plate 33 from shifting laterally. A handle 361 is provided on the end of the stud 362 away from the crossbar 34, which makes it easier and less strenuous to unscrew the stud 362. The top surface of the support 61 is also provided with a guide rail plate 63 that is in contact with the bottom surface of the moving plate 64 and can slide against each other, which helps to make the moving trajectory of the moving plate 64 straighter and avoids it from tilting and affecting the gripping action of the gripping device 67. The top surface of the tray 673 is also provided with a side-push cylinder 674. The end of the side-push cylinder 674 is fixedly connected to one side of the template fixing device 676, which is beneficial to enable the template fixing device 676 to move laterally under the action of the side-push cylinder 674, thereby enabling the template fixing device 676 to obtain a larger lateral movement range and greater flexibility of use. The top edge of the gripping tray 71 is also provided with a positioning stud 75, which is convenient to turn the positioning stud 75 to move it up and down. By moving the lower end of the positioning stud 75 up and down, it can make the lower end abut against the template when the gripping tray 71 is moved to a suitable height during the gripping process. This means that when gripping the template, there is no need to wait for the gripping tray 71 to be fully lowered, and the gripping speed is faster.

[0040] An adjustment piece 500 is also provided on one edge of the second placement plate 422. A fastening bolt is detachably engaged on the adjustment piece 500. The adjustment piece 500 is detachably connected to the tray 421 through the fastening bolt. This is convenient because when it is necessary to adjust the distance between the second placement plate 422 and the first placement plate 423, it is only necessary to loosen the fastening bolt, so that the second placement plate 422 is no longer fixed to the tray 421. This allows the second placement plate 422 to be moved, thereby changing the gap between the first placement plate 423 and the second placement plate 422. After adjusting to the required position, it is only necessary to tighten the fastening bolt to re-fix the second placement plate 422, making it simpler and more convenient to adjust the distance between the first placement plate 423 and the second placement plate 422.

[0041] Working principle of the invention: In use, the fabric to be formed into a pocket is placed on the dividing device 4. After the fabric is placed in, it needs to be fixed by the pressing device 425. The front cylinder 426 on the back plate of the pressing device 425 can control the overall height of the pressing device 425, thereby controlling the position of the lifting plate 13. After the fabric is loaded, the pressing cylinder 16 can drive the pressing frame 15 to descend, so that the pressing frame 15 presses on the fabric, thereby achieving the effect of fixing the fabric. The top of the dividing device 4 can move laterally along the transverse track 51 instead of being fixedly mounted on the processing table 2. The first horizontal pull cylinder 429 and the second horizontal pull cylinder 428, as well as the first fabric pulling frame 427 and the second fabric pulling frame 432 of the slitting device body 42 are all mounted on the tray 421 and can move with the tray 421. Therefore, during the movement of the slitting device 4, the first horizontal pull cylinder 429 and the second horizontal pull cylinder 428 can be driven synchronously to move the first fabric pulling frame 427 and the second fabric pulling frame 432 along the lower surfaces of the first and second placement plates 423 and 422. When passing the laser opening 21, the laser emitted by the laser emitter 60 can be emitted through the laser opening 21, thereby cutting the fabric and creating an opening. After the fabric is laser-cut, the slitting frame 44 descends, causing the pressure plate 35 of the slitting frame 44 to move downwards, thus separating the cut portion of the fabric and opening the cut opening. Subsequently, the first horizontal pull cylinder 429, in conjunction with the second horizontal pull cylinder 428, moves the first fabric pulling frame 427 and the second fabric pulling frame 432. Guided by the sliding rod 83 on the rising plate 82 and the tray 421, the fabric pulling frame body 81 moves the first fabric pulling frame 427 and the second fabric pulling frame 432 closer to the opening of the fabric. When they move to the position of the gap formed by the first placement plate 423 and the second placement plate 422, the fabric pulling grid 84 loses contact with the first placement plate. The first horizontal pull cylinder 423 and the second horizontal pull cylinder 428 are pulled back, so that the first fabric pull frame 427 and the second fabric pull frame 432's fabric pull grid 84 can pull open the cut position of the fabric to form a pocket opening. The above structures are all integrated on the tray 421, rather than fixed on the processing table 2. Therefore, the step of opening the pocket can be carried out simultaneously during the moving step of the slitting device 4, without having to move the fabric to a fixed position to open the pocket before opening the bag and then carrying out the next moving step, making the processing speed of the fabric pocket faster and the processing efficiency higher. Simultaneously, during the bag opening process, a bag fabric template needs to be placed at the starting position of the slitting device 4, and the bag fabric is loaded onto the template. Then, the fabric with the pocket opening moves to the position of the bag fabric template as the slitting device 4 moves. During the opening process of the slitting device 4, the push-pull cylinder 45 of the fabric lifting device is in an extended state, preventing the fabric support plate 430 from directly contacting the fabric. After the opening is completed and the slitting device 4 moves to the position of the bag fabric template, the push-pull cylinder 45 is pulled back, causing it to retract and move the fabric support plate 430. The fabric support plate 430 is then inserted under the template containing the bag fabric for lifting, working in conjunction with the tray 421 of the separating device body 42 to hold the bag... The fabric is clamped and fixed, so that when the template of the bag fabric is pulled away by the gripping device 6, the bag fabric can be clamped, fixed and lifted, so that the bag fabric will not be pulled by the template and become skewed. At the same time, compared with the existing top column fixing device, the cover plate 430 has a larger coverage area, which can accommodate smaller bag fabrics and has better adaptability. Then, the sewing template of the sewing machine head can be fed in by the gripping device 6 and the sewing template is inserted under the bag fabric and the opening fabric. At this time, the bag fabric and the opening fabric can be moved to the position of the sewing machine head 3 by the piece separating device 4 for sewing, thereby sewing and fixing the bag fabric and the opening fabric into shape, thus forming a finished fabric product with a pocket. Simultaneously, after opening the bag and overlapping it with the opened fabric, the template for placing the bag can be removed using the gripping device 6. During the gripping process, the moving plate 64 is moved laterally on the support by rotating the motor 66 in conjunction with the screw 65, while the rotating column 678 is rotated by the rotating cylinder 69 in conjunction with the connecting rod 671, thereby causing the placement tray 673 loaded on the rotating column 678 to rotate synchronously. This, combined with the hook 711 on the gripping device 6 and the gripping hook 74 which can be controlled to open and close by the gripping cylinder 72, allows the gripping cylinder to... When 72 extends, the inner end of the gripping hook 74 is pushed outward by the moving block 73, causing its outer end to retract. At this time, it can work with the hook 711 to grip the columnar protrusion on the template. The thrust generated by the rotating cylinder 69 causes the template fixing device 676 to rotate, quickly separating the template from the separating device 4. Compared with the traditional servo mechanism driven transverse device, separating the template by rotation makes the separation speed faster, and there is no need to set up a complex servo transmission mechanism. The structure is simpler, the operation is easier, and the maintenance is more convenient.
