In related garment sewing processes, when using a rib knitting machine to process ribbed fabric for cuffs, tube openings, and necklines (which are tubular), the ribbed cuffs processed by the cuff rib knitting machine need to be tubular. In this case, for ordinary sewing machines, feeding the ribbed cuff fabric with seams into the sewing machine requires entirely manual operation by the sewing machine operator. Inaccurate seam positioning leads to low seam adjustment efficiency. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0014] Please refer to the following: Figures 1 to 3 This application provides a boning mechanism 100 for use in a sewing device 1000. The sewing device 1000 includes a sewing mechanism 200 for sewing a first fabric 201 and a second fabric 202 fitted onto the first fabric 201. The second fabric 202 includes one or more boning points. The boning mechanism 100 includes a boning detection device 10 and a boning device 20. The boning detection device 10 is electrically connected to the boning device 20. The boning device 20, upon startup, presses and tilts one boning point of the second fabric 202 to complete the boning process. The boning detection device 10 locates boning points on the second fabric 202 before the sewing mechanism 200 sews the first fabric 201 and the second fabric 202 together, and sends a boning signal to the boning device 20 when two or more boning points are located. The boning device 20 presses and tilts two or more boning points in the same direction according to the boning signal to complete the boning process.

[0015] Specifically, the first fabric 201 can be cuff ribbing, and the second fabric 202 can be the sleeve. This application utilizes a tensioning and rotating mechanism 300 to expand the cuff ribbing, and then the sleeve is fitted over the cuff ribbing. After the cuff ribbing and sleeve are fitted, the tensioning and rotating mechanism 300 can hold the cuff ribbing and sleeve in place using a stretching rod at one end and another. During sewing, the stretching rods on the tensioning and rotating mechanism 300 can rotate in coordination with the operating speed of the sewing mechanism 200, thereby controlling the stable position of the cuff ribbing and sleeve during sewing and preventing fabric shifting during the sewing process.

[0016] It should be noted that the tensioning rotation mechanism 300's expansion rods are respectively located on the left and right sides of the fabric sewing position, and the expansion rods are in... Figure 1Only one is shown in the diagram, labeled 301; the other is not shown. The tensioning rotation mechanism 300 can control the distance between the two tensioning rods by the pressure of the cylinder, and can also drive the tensioning rods to rotate via gear transmission or other transmission components.

[0017] The bone-finding detection device 10 of the boning mechanism 100 can be a laser distance sensor. Understandably, in the garment manufacturing process, garments go through multiple stages from fabric to cut pieces to finished sewing. In these stages, the cooperation of manual labor and equipment is often required to complete the sewing work. A garment is made by sewing together several cut pieces. During the sewing process, the overlapping areas of the front cut piece located at the chest and the back cut piece located at the back of the body need to be sewn together, forming the "edge seam." After the edge seam is completed, a bone structure is formed on the fabric of the semi-finished garment, which can be used to position the fabric during subsequent processing.

[0018] A seam is the joint formed when the front and back fabrics of a garment are sewn together. It is created by overlapping and sewing two layers of fabric, so the thickness at the seam is greater than that of other parts of the fabric. Therefore, during garment manufacturing, seam detection is often used to position the garment. This application uses a distance sensor to detect the thickness of the fabric, thereby determining the location of the seam. By setting a seam threshold in the distance sensor, the sensor outputs a seam detection signal, thus identifying the seam. Therefore, when two layers of an initial piece of second fabric 202 are folded in half and then overlapped and sewn together to form a sleeve, one relatively thick seam is formed; when multiple initial pieces of second fabric 202 are sewn together in pairs to form sleeves, multiple relatively thick seams are formed.

[0019] On the one hand, when there is only one bone position on the second fabric 202 after sewing, the bone-finding detection device 10 does not need to be started at this time. The bone-reversing device 20 of the bone-reversing mechanism 100 can press and tilt the bone position on the second fabric 202 corresponding to the sewing point between the first fabric 201 and the second fabric 202 after starting, so as to complete the bone-reversing process.

[0020] On the other hand, when there are multiple bone positions in the sewn second fabric 202, the bone-finding detection device 10 will start working and find two or more bone positions. When it finds two or more bone positions, it can send a bone-reversing signal to the bone-reversing device 20, so that the bone-reversing device 20 can press and tilt two or more bone positions in the same direction according to the bone-reversing signal sent by the bone-finding detection device 10 to complete the bone-reversing process.

[0021] Among them, the single bone position of the second fabric 202 refers to, for example, Figure 1 The single strip shown extends from the first end to the second end of the second fabric 202, for example... Figure 1 It has two long strips, bone position A and bone position B, and the bone positions A and B are tilted in different directions.

[0022] The position of the bone structure when pressing down the bone structure of the second fabric 202 can be as follows: Figure 1 The small area indicated by the arrow in the diagram. That is, the bone position pressing position of this application is located at the bone position within a small area corresponding to the required seam connection between the first fabric 201 and the second fabric 202. The pressing width of the bone position within this small area can be greater than or equal to the seam width corresponding to the required seam connection between the first fabric 201 and the second fabric 202.

[0023] Thus, the rib-setting mechanism 100 of this application includes a rib-finding detection device 10 and a rib-setting device 20, which can automatically press down the sleeve for one or more rib positions, meet the requirements of the factory for the rib-setting process when sewing cuff ribbing, and improve the rib-setting efficiency.

[0024] Please see Figure 4 In some embodiments, the bone-finding detection device 10 includes a signal transmitting module 11 and a signal receiving module 12. The signal receiving module 11 is electrically connected to the bone-setting device 20, and the signal transmitting module 11 is used to transmit bone position detection signals. The signal receiving module 12 is used to receive the bone-setting signals returned by the bone positions after the bone position detection signals pass through the second fabric 202, and send the bone-setting signals to the bone-setting device 20, so that the bone-setting device 20 can press and tilt two or more bone positions in the same direction according to the bone-setting signals, thereby completing the bone-setting process.

[0025] Specifically, the bone position detection signal refers to the detection signal that has not been returned by the second fabric 202. The reverse bone signal refers to the detection signal that has been returned by the bone position through the second fabric 202.

[0026] The bone position detection signal can be a laser signal or other signals, and there are no restrictions here. For example, when the bone-finding detection device 10 is a laser distance sensor, the bone position detection signal is a laser signal, and the bone-reflection signal is the returned laser signal.

[0027] Understandably, the signal transmission angle of the signal transmission module 11 and the signal reception angle of the signal reception module 12 in the bone-finding detection device 10 of this application can remain fixed. When the bone-finding detection device 10 is started, the tensioning and rotating mechanism 300 of the sleeve, which is covered by the first fabric 201 and the second fabric 202, can simultaneously start rotating, so that the sleeve changes position with the tensioning and rotating mechanism 301 to correspond to the bone position detection signal emitted by the bone-finding detection device 10. This allows the sleeve to rotate and sequentially pass through the bone position detection signal for bone-finding detection, so that the bone-finding detection device 10 can perform real-time and comprehensive detection of the presence of bone positions on the corresponding parts of the second fabric 202.

[0028] The bone-tilting device 20 presses and tilts two or more bones in the same direction according to the bone-tilting signal, completing the bone-tilting process. The same direction can be the direction of one side of the bone-tilting device 20. For example... Figure 3 As shown, the direction of pressing and tilting during the bone-reversing process can be as follows: Figure 3 The X-axis direction is shown.

[0029] Thus, the bone-finding detection device 10 of this application can detect in real time whether there are more than two bone positions in the sewn second fabric 202, and then send a bone-removing signal to the bone-removing device 20 in a timely manner, so that the bone-removing device 20 can remove bone from more than two bone positions and complete the bone-removing process.

[0030] Please see Figure 1 and Figure 5 In some embodiments, the bone-finding detection device 10 further includes a bone position marking module 13, which is electrically connected to the sewing mechanism 200. The bone position marking module 13 is used to mark two or more bone positions and send marking signals to the sewing mechanism 200. The marking signals can be voltage signals or current signals, and there is no limitation on this.

[0031] like Figure 1 As shown, when there are four skeletal positions, the skeletal positions include the initial skeletal position A and the final skeletal position B. In this case, the initial skeletal position A is the second skeletal position after the first skeletal position. Please refer to [link / reference]. Figure 5 The sewing mechanism 200 includes a sewing component 210, a sewing presser foot 220, and a presser foot control component 230. The sewing component 210 is connected to the sewing presser foot 220. The bone position marking module 13 is electrically connected to the first end of the presser foot control component 230, and the second end of the presser foot control component 230 is electrically connected to both the sewing component 210 and the sewing presser foot 220. The presser foot control component 230 controls the sewing component 210 and the sewing presser foot 220 to continue sewing operations according to the marking signal until a first distance d1 is separated from the end bone position B, so that the sewing component 210 and the sewing presser foot 220 stop at the first distance d1 from the end bone position B, and controls the sewing presser foot 220 and the sewing component 210 to be raised to a preset height. The sewing component 210 of this application may include sewing operation parts such as a sewing needle.

[0032] Understandably, if the bone-finding detection device 10 detects two bone positions on the second fabric 202, the presser foot control component 230 can control the sewing component 210 to continue sewing operations according to the marking signal until it reaches a first distance d1 away from the end bone position B, so that the sewing presser foot 220 stops at a first distance d1 away from the end bone position B, and controls the sewing presser foot 220 to be raised to a preset height h, forming the raised posture of the sewing presser foot 220.

[0033] Wherein, the first distance d1 is the distance between the center projection point obtained by the orthographic projection of the sewing presser foot 220 on the horizontal plane where the second fabric 202 is located and the end bone position B. The preset height h is the vertical height between the lowest point of the sewing presser foot 220 and the horizontal plane where the second fabric 202 is located.

[0034] That is, before the bone-removing device 20 is started, the bone-finding detection device 10 of this application can mark the specific sewing position of two or more bone positions, thereby obtaining a marking signal, and sending the marking signal to the sewing mechanism 200, so that the presser foot control component 230 of the sewing mechanism 200 first raises the sewing presser foot 220 to a first distance d1 and a preset height h from the end bone position B, so as not to hinder the subsequent bone-removing device 20 from removing bone from two or more bone positions.

[0035] Furthermore, after the process of debossing the bone positions on the second fabric 202 using the debossing device 20 is completed, the sewing mechanism 200 can then lower the sewing component 210 and the sewing presser foot 220 according to the marking signal to sew the debossed bone positions to complete the debossing process. Additionally, after sewing the debossed bone positions on the second fabric 202, the sewing mechanism 200 can continue to sew the required seam positions after the debossing positions of the first fabric 201 and the second fabric 202 to complete the sewn product.

[0036] In some embodiments, the bob-reversing device 20 is electrically connected to the presser foot control component 230. The bob-reversing device 20 is used to start working after the presser foot control component 230 controls the sewing component 210 and the sewing presser foot 220 to stop at a first distance d1 from the end bob position B and controls the sewing component 210 and the sewing presser foot 220 to be raised to a preset height h.

[0037] That is, before the sewing mechanism 200 sews the first fabric 201 and the second fabric 202, the boning mechanism 100 of this application can control the sewing component 210 and the sewing presser foot 220 to stop at a first distance d1 from the end bone position B, and control the sewing component 210 and the sewing presser foot 220 to raise a preset height h, so as to ensure that there is enough space for boning operation, and then let the boning device 20 start to work and carry out the boning process, so as to ensure the efficiency of boning.

[0038] Please see Figure 3 In some embodiments, the bone-tilting device 20 includes a bone-tilting component 21 and a driving component 22. The driving component 22 is connected to the bone-tilting component 21 and is used to lock the position of the bone according to the bone-tilting signal, drive the bone-tilting component 21 to descend vertically to a position region parallel to the bone at a second distance d2, and move horizontally along a first direction to tilt the bone in the first direction.

[0039] The sewing mechanism 200 includes a sewing component 210, a sewing presser foot 220, and a presser foot control component 230. The presser foot control component 230 is electrically connected to the sewing component 210 and the sewing presser foot 220 respectively, and is also electrically connected to the drive component 22. After receiving the end-of-work signal from the drive component 22, the presser foot control component 230 controls the sewing component 210 and the sewing presser foot 220 to descend vertically to sew the tilted bone.

[0040] Specifically, the end-of-work signal refers to the electrical signal emitted by the drive component 22 that indicates the completion of tilting all detected bone positions in the first direction. The tilting component 21 can be as follows: Figure 3 The inverted bone pick shown.

[0041] The bone-tilting device 20 of this application tilts all bone positions in the first direction through the bone-tilting component 21. Even if the bone positions tilt in the same direction, the tilting direction of the bone positions is more uniform, which makes the success rate of subsequent sewing of the bone positions by the sewing component 210 and the sewing presser foot 220 higher.

[0042] Thus, after receiving the end-of-work signal from the drive unit 22, the presser foot control component 230 of this application can control the sewing component 210 and the sewing presser foot 220 to descend vertically to sew the tilted bone position, thereby realizing the complete bone tilting process.

[0043] Please see Figure 3 In some embodiments, the bone-setting device 20 further includes an air-blowing component 23. The air-blowing component 23 is connected to the drive component 22 and is used to start working simultaneously after receiving a start signal from the drive component 22, and to blow out gas in a first direction to assist in bone setting and prevent the bone from rebounding after being pressed and tilted.

[0044] That is, the bone-setting device 20 of this application can also be provided with an air-blowing component 23. The air-blowing component 23 may include components such as an air inlet, a small air pump, and an air delivery pipe 231. The small air pump and the air delivery pipe 231 accurately blow air from the air inlet towards the first direction of bone tilting, assisting in bone tilting and preventing the bone from rebounding after being pressed and tilted, thereby improving the efficiency of subsequent bone suturing. The air delivery pipe 231 may be hook-shaped or other shapes, without limitation. The air delivery pipe 231 may be made of rigid materials such as stainless steel or soft materials such as silicone, without limitation.

[0045] The air blowing component 23 can be set to start when the drive component 22 is started, or to stop when the drive component 22 is stopped, that is, it can work synchronously and stop working.

[0046] In other embodiments of this application, the air blowing component 23 can also be set to start when the drive component 22 is activated, and continue to work until the sewing component 210 and the sewing presser foot 220 complete the sewing work on the tilted bone position and then automatically stop working. The design of the air blowing auxiliary time in the air blowing component 23 is more flexible.

[0047] Please see Figure 3 In some embodiments, the driving component 22 includes a first cylinder 221 and a second cylinder 222. The first cylinder 221 is used to drive the reverse bone component 21 to descend vertically to a parallel position region at a second distance d2 from the bone position. The second cylinder 222 is used to drive the reverse bone component 21 to move horizontally in a first direction.

[0048] That is, in the retractor mechanism 100 of this application, the retractor component 21 can be driven in the vertical direction by two cylinders respectively (i.e., Figure 1 (Positive and negative directions of the Z-axis) and along the horizontal direction (i.e. Figure 1 The movement of the X-axis (positive and negative directions) enables the tilting and pressing action of the tilting component 21 on the bone position.

[0049] In detail, after the material loading process is completed, the sewing mechanism 200 starts operating. At this time, driven by the first cylinder 221, the bobbin component 21 can descend along the Z-axis. Subsequently, pushed by the second cylinder 222, the bobbin component 21 can move along the negative X-axis, causing the bone position to... Figure 1 The first direction, or the negative X-axis direction, is shown in the diagram.

[0050] At the same time, when the tilting component 21 causes the bone to tilt in the first direction, the blowing component 23 can also be activated to prevent the tilted bone from rebounding.

[0051] In some embodiments, the reverse bone component 21 is in the form of a metal sheet, and the reverse bone component 21 contacts the reverse bone surface where the bone is located so that the bone tilts in a first direction.

[0052] That is, the reverse bone component 21 of this application can be a metal sheet made of stainless steel, and the thickness of the metal sheet can be 1.5mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm or 2.7mm, without any limitation.

[0053] Thus, this application can use the metal sheet-shaped reverse bone component 21 to press down on the bone, causing the bone to tilt in the first direction.

[0054] Please see Figure 2In some embodiments, the bone-setting mechanism 100 further includes a bone-finding support 30. The bone-finding detection device 10 is mounted and fixed on the bone-finding support 30, which is set at a preset angle to the horizontal plane toward the second fabric 202, so that the bone-finding detection device 10 can transmit a bone position detection signal to the second fabric 202 and receive the bone-setting signal returned from the bone position.

[0055] Specifically, the osteopathic support 30 can be a metal sheet or plate set at a preset angle to the horizontal plane, such as... Figure 2 As shown, the bone-finding support 30 can also be two integrated metal sheets or plates at a preset angle, and there are no restrictions here.

[0056] The preset angle α can be 30°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 40° or 45°, and there are no restrictions here.

[0057] The bone-finding detection device 10 is mounted and fixed on the bone-finding bracket 30, meaning that the bone-finding bracket 30 is provided with at least one screw hole, and the bone-finding detection device 10 can be mounted and fixed together with the screw hole on the bone-finding bracket 30 by screws or bolts.

[0058] In other embodiments of this application, the bone-finding detection device 10 is installed and fixed on the bone-finding bracket 30 in other ways, which are not limited here.

[0059] Thus, the bone-setting mechanism 100 of this application can support the bone-setting detection device 10 through the bone-setting bracket 30, so that the bone-setting detection device 10 can normally transmit bone position detection signals to the second fabric 202 and receive bone-setting signals.

[0060] Please see Figure 1 This application also provides a sewing device 1000. The sewing device 1000 includes a tensioning and rotating mechanism 400, a sewing mechanism 200, and a boning mechanism 100 as described in any of the above embodiments. The tensioning and rotating mechanism 400 is used to tension and rotate a first fabric 201 and a second fabric 202 sleeved on the first fabric 201. The second fabric 202 includes one or more boning points. The sewing mechanism 200 is used to sew the first fabric 201 and the second fabric 202 together. The boning mechanism 100 is used to press and tilt at least one boning point on the sewn second fabric 202 in the same direction. The sewing mechanism 200 sews the tilted boning point to complete the boning process.

[0061] Specifically, the structure and working principle of the boning mechanism 100, the sewing mechanism 200 and the tensioning rotation mechanism 300 are as described above, and will not be repeated here.

[0062] Thus, the boning mechanism 100 of the sewing equipment 100 of this application includes a boning detection device 10 and a boning device 20, which can automatically press down sleeves for one or more boning positions, meet the requirements of factories for boning process when sewing cuff ribbing, and improve boning efficiency.

[0063] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
