Description

Technical Field

[0001] This application relates to the field of automation, and more particularly to an automatic powder applicator and sewing equipment. Background Technology

[0002] Currently, in the sewing industry, support strips are added during the sewing process to provide support to the seams and prevent wrinkling. This also helps prevent localized wrinkling caused by fabric shrinkage after repeated wear and washing. The support strips are supplied in rolls, and the sewing operator needs to pull them out of the stock roll and straighten them to reduce the probability of knots during sewing. To reduce the stickiness between the support strips after pulling them out, and between the support strips and the presser foot of the sewing machine, lubricant powder needs to be applied to the pulled-out support strips. This prevents adhesion between support strips or between the support strips and the presser foot, which can lead to uneven sewing, knots, or breakage of the support strips. Currently, pulling the support strips out of the stock roll and straightening them, as well as applying lubricant powder, are all done manually, which is not only wasteful of manpower but also inefficient. Furthermore, manually applying lubricant powder to the support strips results in insufficient use of the lubricant, leading to waste. Summary of the Invention

[0003] This application provides an automatic powder applicator and sewing equipment, which realizes automated control of applying lubricating powder to the support belt, saving labor costs and avoiding waste of lubricating powder.

[0004] This application provides an automatic powder applicator, including a powder box and a traction device located on one side of the powder box. The traction device is used to pull out a support belt wound on a material cylinder. The powder box has a receiving space and an inlet and an outlet communicating with the receiving space. The receiving space is used to hold lubricating powder. The inlet is used for the pulled-out support belt to enter the receiving space, and the outlet is used for the pulled-out support belt to pass through the receiving space to adhere to the lubricating powder.

[0005] Furthermore, the automatic powder feeding machine includes a limiting post, the material cylinder is sleeved on the limiting post and can rotate relative to the limiting post, and when the support belt is pulled out from the material cylinder, it drives the material cylinder to rotate.

[0006] Furthermore, the automatic powder feeder includes at least one support rod for supporting a support belt located between the powder box and the material cylinder, and the support rod is provided with a recessed groove for receiving the support belt.

[0007] Furthermore, the automatic powder applicator includes a vibration device located inside or below the powder box, the vibration device vibrating to loosen the lubricating powder in the receiving space.

[0008] Furthermore, the traction device includes a motor, a driving wheel, and a driven wheel. The support belt passes between the driving wheel and the driven wheel. The motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate, so as to pull the support belt off the material cylinder.

[0009] This application also provides a sewing device, including a sewing machine and the above-mentioned automatic powder applicator, wherein the sewing machine is located on one side of the automatic powder applicator, and the sewing machine is used to sew a support strip coated with lubricating powder onto the sewing fabric.

[0010] Furthermore, the automatic powder applicator includes a trigger and a first detection switch. The trigger includes a triggering part and a supporting part. The extended support belt passes under the supporting part. The trigger can move between a first trigger position and a non-trigger position. In the first trigger position, the triggering part triggers the first detection switch, and the motor starts. In the non-trigger position, the motor stops. When the support belt lifts the supporting part, the supporting part moves to move the triggering part to the non-trigger position.

[0011] Furthermore, the first detection switch is provided with a first emitter and a first receiver. In the first trigger position, the trigger part is located between the first emitter and the first receiver to block the light emitted by the first emitter. When the trigger moves from the first trigger position to the non-trigger position, the trigger part moves out from between the first emitter and the first receiver, and the first receiver can receive the light emitted by the first emitter.

[0012] Furthermore, the automatic powder applicator also includes a second detection switch. The trigger can move between a second trigger position and a non-trigger position. When in the second trigger position, the trigger triggers the second detection switch, the sewing machine stops, and when the support belt lifts the abutment, the abutment moves to drive the trigger to the second trigger position.

[0013] Furthermore, the second detection switch is provided with a second light emitter and a second receiver. In the second trigger position, the trigger part is located between the second light emitter and the second receiver to block the light emitted by the second light emitter. When the trigger moves from the second trigger position to the non-trigger position, the trigger part moves out from between the second light emitter and the second receiver, and the second receiver can receive the light emitted by the second light emitter.

[0014] Furthermore, the automatic powder applicator includes a fixed plate with a channel, and the supporting part extends through the channel. When the trigger moves between the first trigger position, the non-trigger position, and the second trigger position, the supporting part moves along the channel.

[0015] Furthermore, the trigger includes a limiting part, which is rotatably connected to the fixed plate. When the supporting part moves along the channel, it causes the limiting part to rotate relative to the fixed plate.

[0016] Furthermore, the sewing equipment also includes a server and a first detector, the first detector being coupled to the server to transmit signals, the first detector being used to detect data of lubricating powder in the powder box and transmit the data to the server.

[0017] Furthermore, the sewing equipment also includes a server and a second detector, the second detector being coupled to the server, the second detector being used to detect the amount of support tape used and to transmit the data of the amount used to the server.

[0018] The automatic powder applicator of this application includes a traction device and a powder box containing lubricating powder. The traction device pulls the support belt from the feed cylinder. As the pulled-out support belt passes through the powder box, it adheres to the lubricating powder. Firstly, this achieves automated control of the lubricating powder adhering to the pulled-out support belt, saving labor costs and improving work efficiency compared to manual application. Secondly, it allows for the use of the entire roll of support belt, avoiding the probability of knots compared to traditional manual pulling. Thirdly, it avoids uneven contact between the lubricating powder and the pulled-out support belt, which is caused by manual application, improving lubrication and sewing effects. Fourthly, the lubricating powder is stored in the powder box, preventing waste and significantly increasing its effective utilization rate, thus saving costs. Fifthly, it also prevents dust generated by the lubricating powder from being exposed to the air, thus avoiding impacts on the working environment and employee health. Attached Figure Description

[0031] In garment factories, support strips 11 are added during the sewing process to provide support and prevent wrinkling. The automatic powder applicator of this application can be applied to garment factories to apply lubricating powder to the pulled-out support strips 11, reducing the stickiness between the support strips 11 and between the support strips 11 and the presser foot 51 of the sewing machine 5, ensuring smooth sewing. The automatic powder applicator includes a powder box 2 for holding lubricating powder. The pulled-out support strips 11 pass through the powder box 2 to adhere the lubricating powder, achieving automated control of the lubricating powder adhesion to the support strips 11. Compared to manually applying the lubricating powder to the support strips 11, this saves labor costs and improves work efficiency; simultaneously, it significantly increases the effective utilization rate of the lubricating powder, saving on the cost of the lubricating powder.

[0032] The support strip 11 can be made of plastic or rubber, such as TPU (thermoplastic polyurethane elastomer). The support strip 11 can be transparent or opaque.

[0033] See Figures 1 to 4 As shown, the automatic powder applicator according to this embodiment includes a powder box 2 and a traction device 3 located on one side of the powder box 2. The traction device 3 is used to pull out the support belt 11 wound on the material cylinder 12. The powder box 2 is provided with a receiving space 21 and an inlet 22 and an outlet 23 communicating with the receiving space 21. The receiving space 21 is used to hold lubricating powder. The inlet 22 is used for the pulled-out support belt 11 to enter the receiving space 21. The outlet 23 is used for the pulled-out support belt 11 to pass through the receiving space 21 to adhere to the lubricating powder.

[0034] The traction device 3 is used to pull the support belt 11 out of the material cylinder 12. When the pulled-out support belt 11 passes through the receiving space 21 of the powder box 2, it can be coated with lubricating powder. Firstly, it realizes the automated control of lubricating powder adhesion to the pulled-out support belt 11, which saves labor costs and improves work efficiency compared to manually adhering the lubricating powder to the support belt 11. Secondly, the material of the support belt 11 can be used in whole rolls, which avoids the probability of the support belt 11 getting tangled after being pulled out compared to the traditional manual pulling out of the support belt 11. Thirdly, it avoids the phenomenon of uneven contact between the lubricating powder and the pulled-out support belt 11 caused by manually sprinkling lubricating powder, thus improving the lubrication effect and sewing effect. Fourthly, the lubricating powder is placed in the powder box 2, which will not cause lubricating powder waste, greatly improves the effective utilization rate of lubricating powder, and saves the cost of lubricating powder. Fifthly, it also avoids the dust generated by the lubricating powder being exposed to the air, which would affect the working environment and the health of employees.

[0035] Preferably, the pulled-out support strip 11 passes through the lubricating powder to adhere to it. Alternatively, the lubricating powder may be sprinkled onto the support strip 11 from above; or the lubricating powder may be thrown upwards from below the support strip 11 to adhere to it.

[0036] Optionally, the traction device 3 includes a motor 31, a driving wheel 32, and a driven wheel 33. The support belt 11 passes between the driving wheel 32 and the driven wheel 33. The motor 31 drives the driving wheel 32 to rotate. The driving wheel 32 drives the driven wheel 33 to rotate, thereby pulling the support belt 11 to pull it off the material cylinder 12. The traction device 3 has a simple structure, reducing the cost of the automatic powder feeder. The driving wheel 32 drives the driven wheel 33 to rotate by friction between itself and the driven wheel 33. The traction device 3 can be any structure capable of moving the support belt 11 to pull it off the material cylinder 12.

[0037] Optionally, the automatic powder feeder includes a limiting post 44. The material cylinder 12 is fitted onto the limiting post 44 and can rotate relative to the limiting post 44. When the support belt 11 is pulled out from the material cylinder 12, it drives the material cylinder 12 to rotate. This prevents the material cylinder 12 from being misplaced, causing the support belt 11 to automatically pull out and become knotted.

[0038] The automatic powder applicator includes at least one support rod 46. The support rod 46 supports the support belt 11 located between the powder box 2 and the material cylinder 12 to ensure smooth movement of the support belt 11. The support rod 46 has a recessed groove (not shown) to accommodate the support belt 11. The pulled-out support belt 11 is accommodated in the recessed groove to prevent displacement during movement, thus ensuring smooth movement of the pulled-out support belt 11.

[0039] The automatic powder applicator includes a vibration device 47 located inside or below the powder box 2. The vibration device 47 vibrates to loosen the lubricating powder in the receiving space 21, preventing the lubricating powder from clumping and ensuring that the support strap 11 can pick up lubricating powder when it passes through the receiving space 21 after being pulled out.

[0040] This application provides a sewing device, including a sewing machine 5 and an automatic powder applicator. The sewing machine 5 is located on one side of the automatic powder applicator. The sewing machine 5 is used to sew a support strip 11 coated with lubricating powder onto the sewing fabric, providing support to the seam and preventing wrinkles.

[0041] The traction device 3 can be located between the sewing machine 5 and the powder box 2. The traction device 3 pulls the front support belt 11, so that the rear support belt 11 passes through the receiving space 21 to pick up the lubricating powder. Alternatively, the traction device 3 can be located between the material cylinder 12 and the powder box 2. When the sewing machine 5 sews the front support belt 11 onto the sewing fabric, it pulls the rear support belt 11 to move, so that the rear support belt 11 passes through the receiving space 21 to pick up the lubricating powder.

[0042] The automatic powder applicator includes a trigger 61 and a first detection switch 62. (See also...) Figure 2 and Figures 5 to 6As shown, the trigger 61 includes a triggering part 611 and a supporting part 612. The pulled-out support belt 11 passes under the supporting part 612. The trigger 61 can move between a first triggering position and a non-triggering position. In the first triggering position, the triggering part 611 triggers the first detection switch 62, and the motor 31 starts to pull the support belt 11 out of the feed cylinder 12; in the non-triggering position, the motor 31 stops, stopping the pulling of the support belt 11 out of the feed cylinder 12. When the traction device 3 pulls the support belt 11 normally, the triggering part 611 is in the first triggering position. When the traction device 3 pulls the support belt 11 abnormally, the support belt 11 stops being pulled out of the feed cylinder 12. As the sewing machine 5 sews the front support belt 11 onto the sewing fabric, when the front support belt 11 becomes shorter and taut, the support belt 11 lifts the supporting part 612 upwards. The supporting part 612 moves to drive the triggering part 611 to the non-triggering position.

[0043] The setup of the trigger 61 and the first detection switch 62 ensures that when the support belt 11 moves abnormally, the motor 31 automatically stops, eliminating the need for manual operation and making it more intelligent.

[0044] The automatic powder coating machine includes a first control device (not shown). The first control device is coupled to the first detection switch 62 to transmit signals. The first control device controls the motor 31 to stop or start according to the signal sent by the first detection switch 62. The first control device can be installed inside the motor 31 or can be installed independently, for example, the first detection switch 62 and the first control device can be fixed to a circuit board.

[0045] The first detection switch 62 includes a first emitter 621 and a first receiver 622. In the first triggered position, the triggering part 611 is located between the first emitter 621 and the first receiver 622 to block the light emitted by the first emitter 621. When the triggering member 61 moves from the first triggered position to the non-triggered position, the triggering part 611 moves out from between the first emitter 621 and the first receiver 622, allowing the first receiver 622 to receive the light emitted by the first emitter 621.

[0046] The automatic powder applicator also includes a second detection switch 63. The trigger 61 can move between a second trigger position and a non-trigger position. In the second trigger position, the trigger 611 triggers the second detection switch 63, and the sewing machine 5 stops to avoid scrapping the sewing fabric. When the traction device 3 pulls the support belt 11 abnormally, the support belt 11 stops being pulled out from the feed cylinder 12. As the sewing machine 5 sews the front support belt 11 onto the sewing fabric, when the front support belt 11 becomes shorter and taut, the support belt 11 lifts the abutment 612 upwards, and the abutment 612 moves to drive the trigger 611 to the second trigger position.

[0047] The second detection switch 63 includes a second emitter 631 and a second receiver 632. In the second triggered position, the triggering part 611 is located between the second emitter 631 and the second receiver 632 to block the light emitted by the second emitter 631. When the triggering member 61 moves from the second triggered position to the non-triggered position, the triggering part 611 moves out from between the second emitter 631 and the second receiver 632, allowing the second receiver 632 to receive the light emitted by the second emitter 631.

[0048] The automatic powder applicator includes a second control device (not shown). The second control device is coupled to the second detection switch 63 to transmit signals. The second control device controls the sewing machine 5 to stop or start based on the signal sent by the second detection switch 63. The second control device can be installed inside the sewing machine 5 or can be installed independently; for example, the second detection switch 63 and the second control device can be fixed to a circuit board.

[0049] The first detection switch 62 and the second detection switch 63 can also be push-button switches or Hall switches, etc.

[0050] To ensure that the surface of the garment is flat after the support band 11 is sewn into it, the tension of the support band 11 needs to be low enough throughout the sewing process. Therefore, the trigger 61 is preferably made of a low-density material, such as carbon fiber or magnesium alloy.

[0051] The automatic powder applicator includes a fixed plate 71. The fixed plate 71 is provided with a channel 711. The supporting part 612 extends out of the channel 711. When the trigger member 61 moves between the first trigger position, the non-trigger position, and the second trigger position, the supporting part 612 moves along the channel 711.

[0052] The non-trigger position can be any position between the first trigger position and the second trigger position.

[0053] The trigger 61 includes a limiting part 613. The limiting part 613 is rotatably connected to the fixing plate 71. When the supporting part 612 moves along the channel 711, it causes the limiting part 613 to rotate relative to the fixing plate 71.

[0054] The first detection switch 62 and the second detection switch 63 are fixed to the fixing plate 71. The first detection switch 62, the second detection switch 63 and the limiting part 613 are located on one side of the fixing plate 71, and the driving wheel 32, the driven wheel 33 and the abutting part 612 are located on the opposite side of the fixing plate 71.

[0055] See Figure 2 and Figure 7 The automatic powder applicator also includes a positioning plate 72, a pair of fixing blocks 73, a pair of elastic elements 74, a pair of knobs 75, a pair of abutting elements 76, a rocker arm 77, and a connecting shaft 78. The positioning plate 72 is arranged parallel to the fixing plate 71. The driving wheel 32 and the driven wheel 33 are located between the fixing plate 71 and the positioning plate 72. One knob 75 is fixed to the positioning plate 72, and the other knob 75 is fixed to the fixing plate 71. The fixing plate 71 is provided with a first sliding groove (not shown). The positioning plate 72 is provided with a second sliding groove (not shown).

[0056] One end of the driven wheel 33 passes through the first slide groove and is fixed to one of the fixing blocks 73, while the other end of the driven wheel 33 passes through the second slide groove and is fixed to the other fixing block 73. The pair of fixing blocks 73 are respectively pressed against a pair of abutting members 76. A portion of one fixing block 73 is received within the first slide groove, and a portion of the other fixing block 73 is received within the second slide groove. The pair of abutting members 76 are respectively fixed to both ends of the connecting shaft 78. The rocker arm 77 is fixed to the connecting shaft 78.

[0057] When the extended support belt 11 is passed between the driving wheel 32 and the driven wheel 33, the distance between them needs to be increased to facilitate the passage of the end of the support belt 11. At this time, rotating the rocker arm 77 rotates the connecting shaft 78, which in turn rotates the abutment 76, causing it to abut against the fixing block 73. This causes the fixing block 73 to move upwards along the first and second sliding grooves, thereby moving the driven wheel 33 upwards and adjusting the distance between the driving wheel 32 and the driven wheel 33 to facilitate the passage of the support belt 11 between them. Then, releasing the rocker arm 77 causes the fixing block 73 to move the driven wheel 33 downwards to press the support belt 11 firmly.

[0058] The elastic element 74 is located between the fixed block 73 and the knob 75. Rotating the knob 75 presses down the fixed block 73 and the elastic element 74 to adjust the gap between the driving wheel 32 and the driven wheel 33, ensuring that sufficient friction is generated between the driving wheel 32 and the driven wheel 33 to drive the support belt 11 to move.

[0059] The automatic powder applicator also includes a retaining plate 79. The motor 31 is fixed to the retaining plate 79. The motor shaft of the motor 31 is fixed to the drive wheel 32, so that the motor 31 can drive the drive wheel 32 to rotate. The fixing plate 71 is located between the retaining plate 79 and the positioning plate 72.

[0060] The automatic powder applicator also includes a base plate 701. The fixing plate 71, the positioning plate 72, and the holding plate 79 are fixed to the base plate 701 and located above it. The automatic powder applicator also includes a side plate 702 fixed to the base plate 701. The side plate 702 is located below the base plate 701. The limiting post 44 is fixed to the side plate 702 and located below the base plate 701. The automatic powder applicator also includes a base 703 fixed to the side plate 702. The base 703 is located below the limiting post 44. The base 703 is used to fix the automatic powder applicator to a worktable 9, thereby fixing the automatic powder applicator to the worktable 9. The sewing machine 5 is placed on the worktable 9.

[0061] The garment factory can be a conventional garment factory or a digital garment factory. A digital garment factory is a new production organization method that uses data related to the entire product lifecycle as a basis to simulate, evaluate, and optimize the entire production process in a computer virtual environment, and further extends this to the entire product lifecycle. In a digital garment factory, the amount of lubricating powder used can be detected to assess the cost of lubricating powder input during garment sewing; and / or, the amount of support belt 11 used can be detected to predict the average amount of support belt 11 used per garment, thereby assessing the cost of support belt 11 input during garment sewing.

[0062] When the sewing equipment is used in a digital garment factory, see [reference needed]. Figure 8As shown, the sewing equipment also includes a server 81 and a first detector 82. The first detector 82 is coupled to the server 81 to transmit signals. The first detector 82 is used to detect data of the lubricating powder in the powder box 2 and transmit the data to the server 81. For example, the first detector 82 can detect the height of the lubricating powder in the powder box 2, and the amount of lubricating powder used can be calculated based on the change in the height of the lubricating powder; or, the first detector 82 is a gravity sensor, which calculates the amount of lubricating powder used by detecting the change in the weight of the lubricating powder in the powder box 2, etc. When the sewing machine 5 sews clothes, the average amount of lubricating powder used per garment can be predicted, thereby assessing the cost of lubricating powder input when sewing clothes.

[0063] The first detector 82 can detect the height of the lubricating powder in the powder box 2 by shining light on the lubricating powder.

[0064] The sewing equipment also includes a second detector 83. The second detector 83 is coupled to the server 81. The second detector 83 is used to detect the amount of support belt 11 used and transmit the data of the usage to the server 81. For example, the second detector 83 can directly detect the amount of support belt 11 used; or it can detect the operating time of the motor 31 to calculate the amount of support belt 11 used. When the sewing machine 5 sews clothes, the average amount of support belt 11 used per garment can be predicted, thereby assessing the investment cost of the support belt 11 during garment sewing.
