Description

Technical Field

[0001] This invention relates to the field of sewing machine technology, and in particular to an automatic template forming device and an automatic template forming method. Background Technology

[0002] Currently, sewing machines that use templates to assist in sewing include template machines and template-feeding machines. These types of sewing machines all require the processing of special templates, and the templates cannot be reused. Each time the sewing process is changed, the corresponding templates need to be reprocessed according to the different sewing paths, resulting in high template processing costs. At the same time, template processing requires waiting time, which indirectly affects sewing efficiency and the delivery time of sewing products, leading to low sewing efficiency and extended delivery time. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic template forming device and an automatic template forming method, which can automatically assemble templates to form the required sewing trajectory, so as to overcome the above-mentioned defects of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention provides an automatic template forming device, including a sewing template, a template forming module fixedly disposed above the sewing template, and a template driving module for driving the sewing template to move along the X and Y directions. The sewing template includes a template frame, two rows of splicing strips arranged sequentially along the X direction on the template frame, and a fixing structure detachably connected to the template frame. The two rows of splicing strips are spaced apart along the Y direction to form a gap, and each splicing strip can be moved along the Y direction and placed on the template frame. The fixing structure is used to fix the two rows of splicing strips to the template frame. The template forming module includes a forming rod and a first lifting drive component that drives the forming rod to move up and down along the Z direction. The forming rod can block a single splicing strip from moving along the Y direction within the gap between the two rows of splicing strips or on the side of the two rows of splicing strips away from the gap.

[0006] Preferably, the fixing structure includes fixing plates and screws, with one or more fixing plates placed on each of the two rows of splicing strips, and the screws connecting the fixing plates to the template frame.

[0007] Preferably, the template forming module further includes a rotary drive component for driving the forming rod to rotate, and the bottom end face of the forming rod is provided with an engagement portion that can engage with the head of the screw.

[0008] Preferably, the template forming module further includes a marking pen and a second lifting drive component that drives the marking pen to move up and down along the Z direction.

[0009] Preferably, the template forming module is installed on the housing of the sewing machine.

[0010] Preferably, the template driving module includes a Y-axis guide rail arranged along the Y direction, a movable block disposed on the Y-axis guide rail, a Y-axis driving component for driving the movable block to slide along the Y-axis guide rail, a clamp mounted on the movable block for clamping the sewing template, and an X-axis driving component for driving the Y-axis guide rail to move along the X direction.

[0011] This invention also provides an automatic template forming method, employing the automatic template forming device described above, comprising the following steps: Step 1, acquiring the sewing trajectory; Step 2, arranging multiple splicing strips sequentially along the X-direction on the template frame to form two rows of splicing strips spaced apart along the Y-direction, and placing the fixing structure on the two rows of splicing strips; Step 3, the first lifting drive component of the template forming module drives the forming rod to descend into the gap between the two rows of splicing strips or to the side of the two rows of splicing strips away from the gap, and the template driving module drives the sewing template to move along the X and Y directions according to the sewing trajectory, so that the position of the forming rod is opposite to the splicing strip whose position needs to be adjusted, and causes the single splicing strip blocked by the forming rod to generate a relative displacement along the Y-direction with the template frame, until the gap matches the sewing trajectory; Step 4, connecting the fixing structure to the template frame, so that the two rows of splicing strips are fixed to the template frame.

[0012] Preferably, the template forming module further includes a marking pen and a second lifting drive component that drives the marking pen to move up and down in the Z direction. The automatic template forming method further includes step five: the first lifting drive component of the template forming module drives the forming rod to rise up and leave the sewing template; the template driving module drives the sewing template to move so that the position on the sewing template where the limiting strip needs to be pasted is below the marking pen; the second lifting drive component drives the marking pen to descend and contact the sewing template; and the template driving module drives the sewing template to move to complete the marking.

[0013] Preferably, the method further includes the following steps: Step 6, repeating steps 2 to 5 to form multiple sewing templates with sewing tracks; Step 7, splicing the multiple sewing templates together and attaching limiting strips to the marked lines on each sewing template.

[0014] Compared with the prior art, the present invention has significant progress:

[0015] By combining the template forming module and the template driving module, the relative positions of each pair of opposite splicing strips along the Y direction in the two rows of splicing strips of the sewing template can be automatically adjusted, so that the gap between the two rows of splicing strips forms the required sewing trajectory. This enables automatic splicing and assembly of the sewing template and replacement and adjustment of the sewing trajectory, thereby enabling the reuse of the sewing template. It can significantly save template production time, speed up template changeover, reduce template production costs, and improve sewing efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0046] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides an automatic template forming device.

[0047] See Figure 1 , Figure 2 and Figure 3 The automatic template forming device in this embodiment includes a sewing template 1, a template forming module 2, and a template driving module 3.

[0048] Among them, see Figure 2 The sewing template 1 includes a template frame 11, splicing strips 12, and a fixing structure 13. Multiple splicing strips 12 are arranged in two rows on the template frame 11. Both rows of splicing strips 12 are arranged sequentially along the X-direction, and the two rows of splicing strips 12 are spaced apart along the Y-direction, forming a gap 14. Each splicing strip 12 can be moved along the Y-direction on the template frame 11. The fixing structure 13 is detachably connected to the template frame 11 and is used to fix the two rows of splicing strips 12 to the template frame 11.

[0049] Template forming module 2 is fixedly installed above sewing template 1, see [reference]. Figure 3 The template forming module 2 includes a forming rod 21 and a first lifting drive (not shown in the figure) that drives the forming rod 21 to move up and down in the Z direction. The forming rod 21 can be inserted into the gap 14 between two rows of splicing strips 12 and block a single splicing strip 12 from moving in the Y direction within the gap 14 between the two rows of splicing strips 12. The forming rod 21 can also block a single splicing strip 12 from moving in the Y direction on the side of the two rows of splicing strips 12 away from the gap 14.

[0050] Template driving module 3 drives sewing template 1 to move along the X and Y directions.

[0051] In use, the template frame 11 can be placed below the template forming module 2, and multiple splicing strips 12 can be arranged sequentially on the template frame 11 along the X direction to form two rows of splicing strips 12 with a gap 14 between them along the Y direction. The fixing structure 13 is placed on the two rows of splicing strips 12, and the fixing structure 13 limits the two rows of splicing strips 12 in the X and Z directions, so that the two rows of splicing strips 12 can move along the Y direction between the template frame 11 and the fixing structure 13. Then, the gap 14 between the two rows of splicing strips 12 is adjusted. Specifically, the first lifting drive of the template forming module 2 drives the forming rod 21 to descend into the gap 14 between the two rows of splicing strips 12 or to the side of the two rows of splicing strips 12 away from the gap 14. The template driving module 3 first drives the sewing template 1 to move along the X direction according to the sewing trajectory to make the position of the forming rod 21 opposite to the splicing strip 12 whose position needs to be adjusted. Then, it drives the sewing template 1 to move along the Y direction so that the single splicing strip 12 blocked by the forming rod 21 makes contact with the template frame 11 along the Y direction. The relative displacement in the Y direction can increase the spacing between two opposite splicing strips 12 in the Y direction when the forming rod 21 blocks the movement of a single splicing strip 12 in the gap 14 between the two rows of splicing strips 12; when the forming rod 21 blocks the movement of a single splicing strip 12 in the Y direction on the side of the two rows of splicing strips 12 away from the gap 14, it can decrease the spacing between two opposite splicing strips 12 in the Y direction. The combination of these two can adjust the spacing position and spacing between two opposite splicing strips 12 in the Y direction, thereby achieving the required sewing trajectory (such as a curve). This adjusts the relative positions of each pair of Y-direction-oriented splicing strips 12 in the two rows of splicing strips 12 until the gap 14 between the two rows of splicing strips 12 is adjusted to match the required sewing trajectory. The first lifting drive of the template forming module 2 drives the forming rod 21 to rise away from the splicing strips 12, and then connects the fixing structure 13 to the template frame 11, fixing the two rows of splicing strips 12 to the template frame 11, thus forming a sewing template 1 with the required sewing trajectory. When it is necessary to change the sewing trajectory of the sewing template 1, the fixed connection between the fixing structure 13 and the template frame 11 is released, allowing the two rows of splicing strips 12 to move along the Y-direction between the template frame 11 and the fixing structure 13. The process of adjusting the gap 14 between the two rows of splicing strips 12 is then repeated to obtain a sewing template 1 with a new sewing trajectory.

[0052] The automatic template forming device of this embodiment, through the cooperation of the template forming module 2 and the template driving module 3, can automatically adjust the relative position of each pair of opposite splicing strips 12 in the two rows of splicing strips 12 along the Y direction in the sewing template 1, so that the gap 14 between the two rows of splicing strips 12 forms the required sewing trajectory, realizing the automatic splicing and assembly of the sewing template 1 and the replacement and adjustment of the sewing trajectory. This enables the reuse of the sewing template 1, which can significantly save template production time, speed up template changeover, reduce template production cost, and improve sewing efficiency.

[0053] See Figure 1 In this embodiment, the automatic template forming device is preferably configured in a sewing machine that uses a template. The sewing machine includes a sewing machine 4 and a table 5. The sewing machine 4 is mounted on the table 5, and the sewing template 1 is placed on the table 5 and located below the head of the sewing machine 4. The template driving module 3 is mounted on one side of the table 5 and is used to drive the sewing template 1 to move along the X and Y directions on the table 5. The template forming module 2 is preferably mounted on the housing of the sewing machine 4. Ideally, the template forming module 2 is mounted and fixed on the housing of the sewing machine 4 and located at the head of the sewing machine 4. Thus, when it is necessary to change the sewing trajectory, the sewing template 1 can be automatically spliced ​​and assembled directly on the sewing machine.

[0054] See Figure 2 In this embodiment, preferably, the fixing structure 13 in the sewing template 1 includes a fixing plate 131 and screws 132. One or more fixing plates 131 are placed on each of the two rows of splicing strips 12, and the screws 132 connect the fixing plates 131 to the template frame 11. When it is necessary to adjust the gap 14 between the two rows of splicing strips 12, the screws 132 are inserted into the fixing plates 131 in a loose state, so that the two rows of splicing strips 12 can move along the Y direction between the template frame 11 and the fixing structure 13. After the gap 14 between the two rows of splicing strips 12 is adjusted, the screws 132 are tightened to fix the fixing plates 131 to the template frame 11, thereby fixing the two rows of splicing strips 12 to the template frame 11.

[0055] Further, see Figure 3 In this embodiment, the template forming module 2 may further include a rotation drive 22 for driving the forming rod 21 to rotate. The bottom end face of the forming rod 21 is provided with an engagement portion that can engage with the head of the screw 132. When it is necessary to tighten or loosen the screw 132, the template driving module 3 can drive the sewing template 1 to move until the screw 132 is directly below the forming rod 21. Then, the first lifting drive of the template forming module 2 drives the forming rod 21 to descend until the engagement portion of the bottom end face of the forming rod 21 engages with the head of the screw 132. Then, the rotation drive 22 drives the forming rod 21 to rotate, thereby allowing the forming rod 21 to drive the screw 132 to rotate, thus completing the tightening or loosening of the screw 132.

[0056] Preferably, in this embodiment, the template forming module 2 further includes a mounting plate 23, which is fixedly connected to the housing of the sewing machine 4. The forming rod 21 is mounted on the rotary drive component 22, which is fixedly mounted on the first slider 26 by a first fastener 25. The first slider 26 is slidably disposed on the mounting plate 23 in the Z direction. The first lifting drive component is connected to the first slider 26 and drives the first slider 26 to move up and down in the Z direction on the mounting plate 23, thereby driving the rotary drive component 22 and the forming rod 21 to move up and down in the Z direction by the first slider 26.

[0057] In this embodiment, the form of the first lifting drive component is not limited; any power component capable of driving the first slider 26 to move up and down on the mounting plate 23 can be used, such as a cylinder, hydraulic cylinder, electric push rod, or linear motor. The form of the rotation drive component 22 is also not limited; any power component capable of driving the forming rod 21 to rotate can be used. Preferably, the rotation drive component 22 can be an automatic screwdriver, with the top end of the forming rod 21 connected to the automatic screwdriver, and the rotation of the automatic screwdriver itself driving the forming rod 21 to rotate.

[0058] See Figure 3 Preferably, the template forming module 2 may further include a marking pen 24 and a second lifting drive (not shown in the figure) that drives the marking pen 24 to move up and down in the Z direction. The marking pen 24 is used to mark lines on the sewing template 1 at the positions where lines need to be marked, such as the positions where the limiting strip 15 needs to be pasted on the sewing template 1, so as to facilitate the pasting of the limiting strip 15. The limiting strip 15 pasted on the sewing template 1 can play the role of positioning the sewing material placed in the sewing template 1. After the sewing template 1 is assembled, the template driving module 3 can drive the sewing template 1 to move so that the position on the sewing template 1 where the limiting strip 15 needs to be pasted is below the marking pen 24. The second lifting drive of the template forming module 2 drives the marking pen 24 to descend until it contacts the sewing template 1, and then the template driving module 3 drives the sewing template 1 to move to complete the automatic marking.

[0059] Preferably, in this embodiment, the marking pen 24 is fixedly mounted on the second slider 28 by the second fastener 27. The second slider 28 is slidably disposed on the mounting plate 23 along the Z-direction. The second lifting drive is connected to the second slider 28 and drives the second slider 28 to move up and down along the Z-direction on the mounting plate 23, thereby causing the marking pen 24 to move up and down along the Z-direction. In this embodiment, the form of the second lifting drive is not limited, and any power component capable of driving the second slider 28 to move up and down on the mounting plate 23 can be used, such as a cylinder, a hydraulic cylinder, an electric push rod, or a linear motor.

[0060] See Figure 1 and Figure 4In this embodiment, preferably, the template driving module 3 includes a Y-axis guide rail 31, a moving block 32, a Y-axis driving component 33, a clamp 34, and an X-axis driving component 35. The Y-axis guide rail 31 is disposed above one side edge of the platform 5 along the Y-axis, and the moving block 32 is slidably disposed on the Y-axis guide rail 31 along the Y-axis. The Y-axis driving component 33 is disposed on the side of the Y-axis guide rail 31 away from the center of the platform 5, and is connected to the moving block 32 and drives the moving block 32 to slide along the Y-axis guide rail 31. The clamp 34 is mounted on the moving block 32 and located on the side of the Y-axis guide rail 31 near the center of the platform 5. The clamp 34 is used to clamp the template frame 11 of the sewing template 1. When the moving block 32 slides on the Y-axis guide rail 31, it drives the sewing template 1 clamped by the clamp 34 to move along the Y-axis. The X-axis drive assembly 35 is positioned below the platform 5 and connected to the Y-axis guide rail 31. The X-axis drive assembly 35 drives the Y-axis guide rail 31 to move along the X-axis, causing the sewing template 1 held by the moving block 32 and the clamp 34 to move along the X-axis as well. This enables the template drive module 3 to drive the sewing template 1 to move along both the X and Y axes.

[0061] In this embodiment, the form of the clamp 34 is not limited, and any existing clamp form can be used, as long as it can clamp and release the sewing template 1.

[0062] See Figure 5 and Figure 6 Preferably, the Y-direction drive assembly 33 includes a first motor 331, a gear 332, and a rack 333. The gear 332 is mounted on the output shaft of the first motor 331, and the rack 333 extends along the Y direction and is mounted on the moving block 32. The gear 332 and the rack 333 mesh with each other. The output shaft of the first motor 331 drives the gear 332 to rotate, and drives the rack 333 to drive the moving block 32 to slide along the Y direction on the Y-direction guide rail 31.

[0063] See Figure 5 and Figure 6Preferably, the X-axis drive assembly 35 includes an X-axis guide rail 351, a slider 352, a second motor 353, a drive wheel 354, a driven wheel 355, and a conveyor belt 356. The X-axis guide rail 351 is disposed below the platform 5 along the X-axis. The slider 352 is slidably disposed on the X-axis guide rail 351 along the X-axis, and the slider 352 is fixedly connected to the Y-axis guide rail 31. The platform 5 has a window 51 for the slider 352 to pass through and connect to the Y-axis guide rail 31, and the window 51 provides displacement space for the slider 352 to slide along the X-axis. The drive wheel 354 is fixedly connected to the output shaft of the second motor 353. The conveyor belt 356 is disposed along the X-axis, and both ends of the conveyor belt 356 are respectively sleeved on the drive wheel 354 and the driven wheel 355. The slider 352 and the conveyor belt 356 are fixedly connected by a connecting plate 357. The output shaft of the second motor 353 drives the drive wheel 354 to actively drive the conveyor belt 356 to run along the X direction. The slider 352, driven by the conveyor belt 356, runs along the X direction on the X-guide rail 351, and drives the Y-guide rail 31 to move along the X direction. Preferably, there can be two sets of X-direction drive components 35, each connected to both ends of the Y-guide rail 31. The driven wheels 355 of the two sets of X-direction drive components 35 are connected through a transmission shaft 358. Therefore, only one set of the drive wheel 354 of the two sets of X-direction drive components 35 needs to be connected to the second motor 353.

[0064] Based on the above-described automatic template forming device, this embodiment of the invention also provides an automatic template forming method. The automatic template forming method of this embodiment uses the automatic template forming device described above, and is also the working method of the automatic template forming device described above. The automatic template forming method of this embodiment includes the following steps in sequence.

[0065] Step 1: Obtain the sewing trajectory. The method for obtaining the sewing trajectory is not limited. The required sewing trajectory can be obtained through the existing sewing trajectory acquisition module of the sewing equipment. This module can acquire the sewing trajectory through visual image acquisition or sensor acquisition, etc. Alternatively, the sewing trajectory can be obtained by directly importing existing sewing trajectories.

[0066] Step 2: Arrange the components of the sewing template 1. Place the template frame 11 at the designated position on the table 5, ensuring that the template frame 11 is below the template forming module 2 fixed at the sewing machine head 4. Arrange multiple splicing strips 12 sequentially along the X-direction on the template frame 11, forming two rows of splicing strips 12 spaced apart by a gap 14 along the Y-direction. The multiple splicing strips 12 can be freely combined with appropriate widths according to the required sewing trajectory shape. Each row of splicing strips 12 should be neatly arranged, and the gap 14 between the two rows of splicing strips 12 should be approximately straight. Then, place the fixing structure 13 on the two rows of splicing strips 12. At this time, the screws 132 of the fixing structure 13 are inserted into the fixing plate 131 in a loose state. The fixing plate 131 and the screws 132 restrict the displacement of the two rows of splicing strips 12 in the X and Z directions, and allow the two rows of splicing strips 12 to move along the Y-direction between the template frame 11 and the fixing plate 131. To ensure that the template frame 11 can move the two rows of splicing strips 12 neatly, preferably, a movable plate can be added under the template frame 11 to support the sewing template 1 as a whole. When the sewing template 1 is moved, the movable plate also moves together, thereby ensuring that the two rows of splicing strips 12 move neatly.

[0067] Step 3: Adjust the gap 14 between the two rows of splicing strips 12 of the sewing template 1 to form a sewing trajectory. The first lifting drive of the template forming module 2 drives the forming rod 21 to descend into the gap 14 between the two rows of splicing strips 12 or to the side of the two rows of splicing strips 12 away from the gap 14. The template driving module 3 drives the sewing template 1 to move along the X and Y directions according to the sewing trajectory, so that the position of the forming rod 21 is opposite to the splicing strip 12 whose position needs to be adjusted, and so that the single splicing strip 12 blocked by the forming rod 21 has a relative displacement with the template frame 11 along the Y direction. Specifically, the template driving module 3 first drives the sewing template 1 to move along the X direction according to the sewing trajectory to be formed, so that the forming rod 21 is opposite to the splicing strip 12 whose position needs to be adjusted, and then drives the sewing template 1 to move along the Y direction. The forming rod 21 moves in the direction of the template frame 11, causing a relative displacement of the individual splicing strip 12 blocked by the forming rod 21 along the Y direction. When the forming rod 21 blocks the movement of a single splicing strip 12 along the Y direction within the gap 14 between the two rows of splicing strips 12, the spacing between the two opposite splicing strips 12 along the Y direction can be increased. When the forming rod 21 blocks the movement of a single splicing strip 12 along the Y direction on the side of the two rows of splicing strips 12 away from the gap 14, the spacing between the two opposite splicing strips 12 along the Y direction can be decreased. The combination of these two actions allows for the adjustment of the spacing position and spacing between the two opposite splicing strips 12 along the Y direction, thereby achieving the desired sewing trajectory (such as a curve). This adjusts the relative position of each pair of opposite splicing strips 12 along the Y direction in the two rows of splicing strips 12 until the gap 14 matches the sewing trajectory. Then, the first lifting drive of the template forming module 2 drives the forming rod 21 to rise and move away from the splicing strips 12.

[0068] Step 4: Sewing template 1 is individually locked. The fixing structure 13 is connected to the template frame 11, fixing the two rows of splicing strips 12 to the template frame 11. In this embodiment, the template driving module 3 drives the sewing template 1 to move until the screw 132 is directly below the forming rod 21. Then, the first lifting drive of the template forming module 2 drives the forming rod 21 to descend until the engagement part of the bottom end face of the forming rod 21 engages with the head of the screw 132. The rotation drive 22 then drives the forming rod 21 to rotate, and the forming rod 21 drives the screw 132 to rotate, completing the tightening of the screw 132. At this point, the two rows of splicing strips 12 are fixed to the template frame 11 and formed into a sewing template 1 with the required sewing trajectory.

[0069] Step 5: Automatic marking on the sewing template 1. The first lifting drive of the template forming module 2 drives the forming rod 21 to rise and leave the sewing template 1. The template driving module 3 drives the sewing template 1 to move so that the position on the sewing template 1 where the limiting strip 15 needs to be attached is below the marking pen 24. The second lifting drive of the template forming module 2 drives the marking pen 24 to descend until it contacts the sewing template 1. The template driving module 3 drives the sewing template 1 to move. As the sewing template 1 moves, the marking pen 24 completes the marking on the sewing template 1. Then, the second lifting drive of the template forming module 2 drives the marking pen 24 to rise and leave the sewing template 1.

[0070] Step 6: Repeat steps 2 to 5 to form multiple sewing templates 1 with sewing tracks.

[0071] Step 7: Join multiple sewing templates 1 together, see... Figure 1 Preferably, multiple sewing templates 1 can be spliced ​​together along the X-direction using splicing adhesive strips 6, and then limiting strips 15 can be pasted on the marked lines on each sewing template 1. The limiting strips 15 pasted on the sewing template 1 can serve to position the sewing material placed in the sewing template 1.

[0072] Then, the cut piece can be placed into the sewing template 1, and the control module of the sewing equipment controls the template drive module 3 and the sewing machine 4 to move synchronously according to the preset sewing program to perform normal sewing.

[0073] When it is necessary to change the sewing trajectory of the sewing template 1, the sewing template 1 can be reused: the fixed connection between the fixed structure 13 and the template frame 11 is released, and the first lifting drive of the template forming module 2 drives the forming rod 21 to descend to the engagement part of the bottom end face of the forming rod 21 and engage with the head of the screw 132. Then, the rotating drive 22 drives the forming rod 21 to rotate, and the forming rod 21 drives the screw 132 to rotate and loosen the screw 132, so that the two rows of splicing strips 12 can move in the Y direction between the template frame 11 and the fixed structure 13. Then, the above steps three and four are performed to obtain the sewing template 1 with a new sewing trajectory.

[0074] The automatic template forming method of this embodiment, through the cooperation of the template forming module 2 and the template driving module 3, can automatically adjust the relative position of each pair of opposite splicing strips 12 in the two rows of splicing strips 12 along the Y direction in the sewing template 1, so that the gap 14 between the two rows of splicing strips 12 forms the required sewing trajectory, realize the automatic splicing and assembly of the sewing template 1 and the replacement and adjustment of the sewing trajectory, thereby realizing the reuse of the sewing template 1, which can significantly save template production time, speed up template changeover, reduce template production cost, and improve sewing efficiency.

[0075] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
