Technical Field

[0001] This utility model relates to the field of sewing processing technology, and in particular to a sewing device. Background Technology

[0002] In the sewing industry, there are situations where two fabrics are sewn together, one inside the other (such as cuffs and cuff ribbing). In actual processing, this requirement is often met by manual sewing, which can easily increase labor costs and result in low sewing efficiency. Utility Model Content

[0003] This invention provides a sewing device to solve at least one of the aforementioned technical problems.

[0004] This utility model provides a sewing device for sewing a first fabric and a second fabric fitted onto the first fabric. The sewing device includes a sewing mechanism and a tensioning and rotating mechanism. The sewing mechanism is used to sew the first fabric and the second fabric. The tensioning and rotating mechanism includes a tensioning part and a holding part. The first fabric and the second fabric can be sequentially fitted onto the tensioning part and kept in a tensioned state. The holding part cooperates with the tensioning part to hold the first fabric and the second fabric, and drives the first fabric and the second fabric to rotate on the tensioning part when the sewing mechanism is sewing.

[0005] The aforementioned sewing equipment has a tensioning section that provides support for the first and second fabrics and keeps them taut. It also works in conjunction with a holding section to hold the first and second fabrics in place, ensuring that the first and second fabrics do not easily shift during the sewing process. During the sewing process, the holding section drives the first and second fabrics to rotate on the tensioning section to coordinate with the sewing action of the sewing mechanism. This helps to improve the automation level of the sewing process, thereby effectively reducing labor costs and increasing production efficiency.

[0015] Please refer to Figure 1 and Figure 2 This invention relates to a sewing device 1000, which can be used to sew a first fabric 101 and a second fabric 102 fitted onto the first fabric 101. The sewing device 1000 may include a sewing mechanism 100 and a tensioning and rotating mechanism 200. The sewing mechanism 100 can be used to sew the first fabric 101 and the second fabric 102. The tensioning and rotating mechanism 200 may include a tensioning part 220 and a holding part 230. The first fabric 101 and the second fabric 102 can be sequentially fitted onto the tensioning part 220 and kept in a tensioned state. The holding part 230 can cooperate with the tensioning part 220 to hold the first fabric 101 and the second fabric 102, and drive the first fabric 101 and the second fabric 102 to rotate on the tensioning part 220 when the sewing mechanism 100 is sewing.

[0016] The aforementioned sewing equipment 1000 has a tensioning part 220 for mounting the first fabric 101 and the second fabric 102 and keeping them taut. It also works in conjunction with the holding part 230 to hold the first fabric 101 and the second fabric 102, ensuring that the first fabric 101 and the second fabric 102 are not prone to shifting during the sewing process. During the sewing process, the holding part 230 drives the first fabric 101 and the second fabric 102 to rotate on the tensioning part 220 to cooperate with the sewing action of the sewing mechanism 100. This helps to improve the automation level of the sewing process, thereby effectively reducing labor costs and improving production efficiency.

[0017] It should be noted that, in Figure 1 In this diagram, directions A1, A2, B1, B2, C1, and C2 serve as reference directions for the sewing equipment 1000. Directions A1 and A2 are opposite to each other, as are directions B1 and B2, and directions C1 and C2. Directions A1, A2, B1, and B2 can all be parallel to the horizontal plane, while directions C1 and C2 can be perpendicular to the horizontal plane.

[0018] In some cases, directions A1, A2, B1, B2, C1, and C2 can correspond to the coordinate axes in a spatial coordinate system. Specifically, direction A1 can be the positive direction of the X-axis, and direction A2 can be the negative direction of the X-axis; direction B1 can be the positive direction of the Y-axis, and direction B2 can be the negative direction of the Y-axis; direction C1 can be the positive direction of the Z-axis, and direction C2 can be the negative direction of the Z-axis.

[0019] Specifically, in Figure 1 and Figure 2 In this configuration, the first fabric 101 and the second fabric 102 can move along direction A2 and be fitted onto the tensioning part 220. The first fabric 101 and the second fabric 102 can be stretched by the tensioning part 220, so that the first fabric 101 and the second fabric 102 are taut on the tensioning part 220 and are in a taut state and can be maintained. The first fabric 101 and the second fabric 102 are fitted onto the tensioning part 220 sequentially. This can be done by first fitting the first fabric 101 onto the tensioning part 220, and then fitting the second fabric 102 as an outer layer of the first fabric 101 onto the tensioning part 220. Alternatively, the first fabric 101 and the second fabric 102 can be layered and fitted onto the tensioning part 220.

[0020] When the first fabric 101 and the second fabric 102 are fitted onto the tensioning part 220 and kept taut, at least a portion of the holding part 230 can move away from or closer to the tensioning part 220, thereby allowing the holding part 230 to abut against the second fabric 102, so that the first fabric 101 and the second fabric 102 are clamped by the tensioning part 220 and the holding part 230. During the sewing process, the holding part 230 can apply a force to the first fabric 101 and the second fabric 102, causing the first fabric 101 and the second fabric 102 to rotate around directions A1 and A2 on the tensioning part 220. This allows the first fabric 101 and the second fabric 102 to move relative to the stitches of the sewing mechanism 100, changing the sewing position on the first fabric 101 and the second fabric 102 as the sewing action progresses, until the sewing mechanism 100 completes the sewing process on the first fabric 101 and the second fabric 102.

[0021] Based on the above, the fixing operation of the first fabric 101 and the moving operation following the sewing action of the second fabric 102 can be realized automatically, without the need for operators to manually maintain the stability and movement of the fabric. This can improve the automation level of the sewing process, reduce labor costs due to the reduction of manual operation, and ultimately help improve production efficiency.

[0022] In some cases, the first fabric 101 can be cuff ribbing, and the second fabric 102 can be the cuff. During actual sewing, the cuff ribbing can be first fitted onto the tensioning part 220, and then the cuff can be fitted onto both the cuff ribbing and the tensioning part 220; that is, the cuff ribbing and the cuff are fitted onto the tensioning part 220 sequentially. It can be understood that in other cases, the first fabric 101 can also be trouser hem ribbing, and the second fabric can also be the trouser hem. During actual sewing, the trouser hem ribbing can be first fitted onto the tensioning part 220, and then the trouser hem can be fitted onto both the trouser hem ribbing and the tensioning part 220; that is, the trouser hem ribbing and the trouser hem are fitted onto the tensioning part 220 sequentially.

[0023] Please refer to Figure 1 and Figure 2 In some cases, the tensioning unit 220 may include a first tensioning rod 221, a second tensioning rod 222, and a first drive member 223. The first tensioning rod 221 and the second tensioning rod 222 may be spaced apart. The first drive member 223 may be connected to the first tensioning rod 221. The first drive member 223 may be used to drive the first tensioning rod 221 to move relative to the second tensioning rod 222.

[0024] In this way, it is convenient to put the first fabric 101 and the second fabric 102 on the tensioning part 220, and the size and structure of the tensioning part 220 can be adjusted according to the size of the first fabric 101 and the second fabric 102, so that the first fabric 101 and the second fabric 102 of different sizes can be sewn.

[0025] Specifically, in Figure 1 and Figure 2In this configuration, the first tensioning lever 221 is located on the side where the second tensioning lever 222 is located along direction A2, or in other words, the second tensioning lever 222 is located on the side where the first tensioning lever 221 is located along direction A1. The first driving member 223 can drive the first tensioning lever 221 to move along direction A1 to approach the second tensioning lever 222, and can also drive the first tensioning lever 221 to move along direction A2 to move away from the second tensioning lever 222. It is understandable that the first tensioning rod 221 and the second tensioning rod 222 are close to each other, which makes it easier for the first fabric 101 and the second fabric 102 to be fitted onto the first tensioning rod 221 and the second tensioning rod 222 (at this time, the first fabric 101 and the second fabric 102 may not be in a tensioned state). The first tensioning rod 221 and the second tensioning rod 222 are far apart from each other, which allows the first tensioning rod 221 and the second tensioning rod 222 to stretch the first fabric 101 and the second fabric 102, thereby allowing the first fabric 101 and the second fabric 102 to enter and maintain a tensioned state, and thus facilitating the loading and fixing of the first fabric 101 and the second fabric 102.

[0026] Furthermore, the first tension bar 221 and the second tension bar 222 can move relative to each other, which can accommodate first fabric 101 and second fabric 102 of different sizes, so that first fabric 101 and second fabric 102 of each size can be in and maintain a tensioned state, thereby enabling sewing processes to be performed on first fabric 101 and second fabric 102 of each size, which helps to improve the applicability of sewing equipment 1000.

[0027] In some cases, the first drive member 223 can control the first spreading member to move a corresponding distance along the A1 or A2 direction according to set parameters, so that the distance between the first spreading member and the second spreading member after the first spreading member moves and stops is just suitable for keeping the first fabric 101 and the second fabric 102 in a tensioned state. The set parameters of the first drive member 223 can be determined according to the size of the first fabric 101 and the second fabric 102. In some cases, the first drive member 223 can be a motor.

[0028] Please refer to Figure 4 In some cases, the tensioning member 220 may include a second drive member 224. The second drive member 224 is connected to the second tensioning rod 222. The second drive member 224 can be used to drive the second tensioning rod 222 to move along its length.

[0029] Thus, the depth of the fabric on the tensioning part 220 can be changed by adjusting the extension length of the second tensioning rod 222, making the fabric more securely attached.

[0030] Specifically, in Figure 4In this configuration, the length direction of the second tensioning rod 222 can be parallel to directions B1 and B2. The second driving member 224 can drive the second tensioning rod 222 to extend along direction B1 and retract along direction B2. When the second tensioning rod 222 is extended relative to the first fabric 101 and the second fabric 102, if the first fabric 101 and the second fabric 102 have a longer length along directions B1 and B2, the second tensioning rod 222 can penetrate deeper into the inner layers of the first fabric 101 and the second fabric 102. This allows more of the first fabric 101 and the second fabric 102 to be fitted onto the tensioning part 220, increasing the contact area between the fabric and the tensioning part 220. This results in the fabric being more securely fitted onto the tensioning part 220, thereby improving the fixing effect on the fabric.

[0031] Please refer to Figure 2 In some cases, the pressure holding part 230 may include a pressure roller 231, a third drive member 232, and a fourth drive member 233. The third drive member 232 may be used to drive the pressure roller 231 to move relative to the tensioning part 220. The fourth drive member 233 may be used to drive the pressure roller 231 to rotate according to the sewing speed of the sewing mechanism 100.

[0032] This helps ensure the stability of the sewing process.

[0033] Specifically, in Figure 2 In the middle, the third driving member 232 can drive the pressure roller 231 to move along the A1 direction to approach the tensioning part 220 and ultimately cooperate with the tensioning part 220 to press the fabric, and can also drive the pressure roller 231 to move along the A2 direction to move away from the tensioning part 220, so that a gap is formed between the tensioning part 220 and the pressure roller 231, making it convenient to put the fabric on the tensioning part 220.

[0034] With the tensioning section 220 and the pressure roller 231 jointly pressing the first fabric 101 and the second fabric 102, the sewing mechanism 100 can begin sewing. During the sewing process, the fourth drive member 233 can drive the pressure roller 231, causing the pressure roller 231 to rotate around its own axis. The rotation of the pressure roller 231 can drive the first fabric 101 and the second fabric 102 to move. Since the first fabric 101 and the second fabric 102 are in a tensioned state, this movement will manifest as the first fabric 101 and the second fabric 102 rotating on the tensioning section 220 in a manner similar to a conveyor belt. This causes the sewing position of the sewing mechanism 100 on the fabric to continuously change around the circumference of the first fabric 101 and the second fabric 102, ultimately sewing the inner and outer fabrics 101 and 102 together.

[0035] The rotational speed of the pressure roller 231 driven by the fourth driving component 233 can be determined by the sewing speed of the sewing mechanism 100. The sewing speed of the sewing mechanism 100 can be expressed as the speed at which the needle of the sewing mechanism 100 passes back and forth across the first fabric 101 and the second fabric 102 to guide the thread. In some cases, the faster the sewing speed of the sewing mechanism 100, that is, the shorter the time required for the sewing mechanism 100 to complete one thread guide, the faster the rotation speed of the pressure roller 231, resulting in faster fabric rotation and thus a faster change in sewing position; conversely, the slower the sewing speed of the sewing mechanism 100, that is, the longer the time required for the sewing mechanism 100 to complete one thread guide, the slower the rotation speed of the pressure roller 231, resulting in slower fabric rotation and thus a slower change in sewing position. Figure 2 In the diagram, the shaft of the pressure roller 231 is designated as L1.

[0036] It is understandable that, due to the force provided by the pressure roller 231 when pressing, the first fabric 101 and the second fabric 102 are less likely to detach from the tensioning part 220 and experience posture deviation, resulting in better control of the first fabric 101 and the second fabric 102. This makes it easier for the first fabric 101 and the second fabric 102 to be driven to perform sewing actions, thereby helping to ensure the stable performance of the sewing action.

[0037] In some cases, the third drive component 232 can be a cylinder, and the fourth drive component 233 can be an electric motor.

[0038] Please refer to Figure 3 and Figure 4 In some cases, the correction mechanism 300 may include a position detection device 310 and a correction device 320. The position detection device 310 is electrically connected to the correction device 320. The position detection device 310 is used to control the correction device 320 to correct the edge position of the second fabric 102 so that the edge position of the second fabric 102 is located at the preset position 301 when the first fabric 101 and the second fabric 102 are sewn together.

[0039] Among them, the preset position 301 can be like... Figure 3 The cuffs shown are positioned parallel and corresponding to each other when sewing after the ribbed cuffs have been fitted.

[0040] Furthermore, the edge position of the second fabric 102 in this utility model refers to, for example... Figure 3 The two fabrics shown are overlapped together and form a certain position A within the edge area.

[0041] Please see Figure 5 and Figure 6In some cases, the position detection device 310 includes a first signal transmitting module 311 and a first signal receiving module 312. The first signal transmitting module 311 is used to transmit a first detection signal, and the first signal receiving module 312 is used to receive a second detection signal returned from the preset position 301 and send the second detection signal to the correction device 320.

[0042] For example, the position detection device 310 can be a photoelectric sensor. Understandably, a photoelectric sensor is a device that converts light signals (visible or invisible light) into electrical signals and uses this change to detect the presence of a target object. That is, the photoelectric sensor can emit a first detection signal to detect whether the preset position 301 has the edge of the second fabric 102. If the edge of the second fabric 102 is located at the preset position 301, a second detection signal indicating the presence of the edge of the second fabric 102 at the preset position 301 can be reflected back from the preset position 301. If the edge of the second fabric 102 is not located at the preset position 301, a second detection signal indicating the absence of the edge of the second fabric 102 at the preset position 301 can be reflected back from the preset position 301.

[0043] The narrow side upper surface of the first correction component 3221 can also be covered with reflective paper. The preset position 301 can be the position where the reflective paper is covered on the narrow side upper surface of the first correction component 3221, so that the first correction component 3221 receives the first detection signal emitted by the position detection device 310 through the reflective paper and reflects it to obtain the second detection signal.

[0044] Please see Figure 3 and Figure 7 In some cases, the correction device 320 includes a control module 321 and a correction module 322. The control module 321 is electrically connected to the correction module 322, and the correction module 322 is in contact with the second fabric 102. The control module 321 is used to receive a second detection signal and control the correction module 322 to start working to correct the edge position of the second fabric 102 so that the edge of the second fabric 102 is located at a preset position 301.

[0045] That is, the control module 321 can receive the second detection signal sent by the position detection device 310, so that when the edge position of the second fabric 102 deviates, the correction module 322 is activated to correct the edge position of the second fabric 102 so that the edge of the second fabric 102 is located at the preset position 301, thus avoiding the problem of fabric deviation during sewing.

[0046] Thus, the correction mechanism 300 of this utility model, through the cooperation of the position detection device 310 and the correction device 320, can correct the deviation that occurs during the sewing of the ribbed cuff, and can effectively avoid the problem of the fabric running off track when the ribbed cuff composed of the first fabric 101 and the second fabric 102 is sewn.

[0047] Please see Figure 3 and Figure 4 In some cases, the correction module 322 includes a first correction component 3221, a second correction component 3222, and a drive component 3223. The second correction component 3222 is spaced apart from the first correction component 3221, and the drive component 3223 is electrically connected to the second correction component 3221 and the control module 321, respectively. The first correction component 3221 has a preset position 301 and is adjacent to the tensioning and rotating mechanism 200 that fixes the second fabric 102. The drive component 3223 receives the drive signal from the control module 321 and drives the second correction component 3222 to move closer to the first correction component 3221 to clamp the second fabric 102, and controls the second correction component 3222 to move back and forth in a first direction as the second fabric 102 is fitted onto the tensioning and rotating mechanism 200.

[0048] Specifically, the first correction component 3221 can be as follows: Figure 4 The diagram shows a sheet-shaped polarization correction light spot illumination plate. The first polarization correction component 3221 is provided with a preset position 301, which means that the preset position 301 can be provided on the detection surface of the first polarization correction component 3221 facing the position detection device 310 as a signal detection area.

[0049] like Figure 4 As shown, the preset position 301 of the first correction component 3221 can be located directly below or diagonally above the position detection device 310, as long as the detection signal can be sent and received. The width of the detection surface of the first correction component 3221 can be greater than or equal to the diameter of the signal light spot, and is not limited here.

[0050] The end 32211 of the first correction component 3221 can be protruding relative to the plane where the preset position 301 is located, which can prevent the second fabric 102 from slipping off when it is put on the first correction component 3221, and prevent the second fabric 102 from slipping off in the opposite direction to the preset position 301 when it is corrected by the second correction component 3222.

[0051] The second correction component 3222 and the first correction component 3221 are set at an interval, which means that the initial interval between the second correction component 3222 and the first correction component 3221 can be 6cm, 7cm, 8cm, 9cm, 10cm, 11cm, 12cm, 13cm, 14cm or 15cm, and there is no restriction here.

[0052] The second correction component 3222 may have a correction surface that contacts the second fabric 102. The friction between the two surfaces promotes the edge of the second fabric 102 to move closer to the preset position 301, ultimately resulting in the edge of the second fabric 102 being positioned at the preset position 301. Specifically, the reciprocating movement of the second correction component 3222 in the first direction of the tensioning and rotating mechanism 200, where the second fabric 102 is fitted onto the fabric, refers to a movement similar to a person lifting the entire fabric consisting of the second fabric 102 and the first fabric 101 towards the fitting direction, thus positioning the edge of the second fabric 102 at the preset position.

[0053] The drive assembly 3223 may include a power drive component such as a motor or cylinder, and is not limited thereto. When the drive assembly 3223 receives a drive signal from the control module 321, indicating that the edge position of the second fabric 102 is not at the preset position 301 (i.e., the second fabric 102 is misaligned), the drive assembly 3223 can drive the second correction assembly 3222 to move closer to the first correction assembly 3221 to clamp the second fabric 102, and control the second correction assembly 3222 to move back and forth in the first direction in which the second fabric 102 is fitted onto the tensioning rotating mechanism 200. This moves the second fabric 102 towards the fitting opening of the tensioning rotating mechanism 200, thereby adjusting the edge position of the second fabric 102. This ensures that during sewing, the second fabric 102 and the first fabric 101 fitted below it do not misalign, improving the sewing efficiency of the ribbed cuff formed by sewing the first fabric 101 and the second fabric 102 together. The first direction includes... Figure 4 The directions B1 and B2 are shown.

[0054] It is understood that the tensioning and rotating mechanism 200 of this utility model is used to put on and stretch the whole piece of cuff fabric formed by combining the first fabric 101 and the second fabric 102, so as to rotate and sew the whole piece of cuff fabric around to form a ribbed cuff.

[0055] Specifically, the first fabric 101 can be cuff ribbing, and the second fabric 102 can be the sleeve. This invention uses a tensioning and rotating mechanism 200 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 200 can clamp the cuff ribbing and sleeve together using a first tensioning rod 221 and a second tensioning rod 222. During sewing, at least one of the first tensioning rod 221 and the second tensioning rod 222 can rotate in conjunction with the operating speed of the sewing mechanism 100, thereby controlling the stable position of the cuff ribbing and sleeve during sewing and preventing fabric shifting during the sewing process.

[0056] It should be noted that the distance between the first tension rod 221 and the second tension rod 222 can be controlled by the pressure of the cylinder, and the first tension rod 221 and / or the second tension rod 222 can be driven to rotate by a gear transmission component or other transmission component.

[0057] Thus, the correction mechanism 300 of this utility model can drive the second correction component 3222 to move back and forth in the first direction of the second fabric 102 being fitted onto the tensioning rotation mechanism 200 by the drive component 3223, thereby correcting the edge position of the second fabric 102 and achieving the effect of fabric correction.

[0058] Please see Figure 3 and Figure 4 In some cases, the second correction assembly 3222 includes a correction wheel 32221. The drive assembly 3223 includes a first motor 32231, which is electrically connected to the correction wheel 32221. The first motor 32231 is used to drive the correction wheel 32221 to reciprocate back and forth along a first direction to correct the edge position of the second fabric 102.

[0059] Specifically, in Figure 3 and Figure 4 In this configuration, the first direction can be parallel to both directions B1 and B2. The straightening wheel 32221 can be a rod-shaped object, and its diameter can be greater than or equal to the diameter of the spreading rod. The length of the straightening wheel 32221 can be slightly less than the length of the second tensioning rod 222, such as... Figure 8 As shown, the length of the correction wheel 32221 can also be greater than or equal to the length of the second tension rod 222. The length of the correction wheel 32221 is sufficient to correct the edge position of the second fabric 102 to the preset position.

[0060] That is, the correction mechanism 300 of this utility model can drive the correction wheel 32221 to move back and forth along the first direction through the first motor 32231, so that the edge position of the second fabric 102 is located at the preset position 301, thereby correcting the deviation of the fabric.

[0061] Please see Figure 4 In some cases, the drive assembly 3223 also includes a second motor 32232. The second motor 32232 is electrically connected to the correction wheel 32221 and is used to drive the correction wheel 32221 to rotate around the wheel center.

[0062] That is, the correction wheel 32221 of this utility model can not only move back and forth in the first direction, but also rotate along the wheel center, so as to play a correction role in the sewing process of the first fabric 101 and the second fabric 102.

[0063] In some cases, the second motor 32232 is also used to update the rotation speed of the correction wheel 32221 in accordance with the sewing speed of the first fabric 101 and the second fabric 102. Alternatively, the second motor 32232 is also used to drive the correction wheel 32221 to rotate according to a preset rotation speed. The preset rotation speed is less than or greater than the sewing speed of the first fabric 101 and the second fabric 102, or the preset rotation speed is a speed segmented according to the circumference length formed by the first fabric 101 and the second fabric 102.

[0064] Specifically, the second motor 32232 is also used to update the rotation speed of the correction wheel 32221 in accordance with the sewing speed of the first fabric 101 and the second fabric 102, meaning that the rotation speed of the correction wheel 32221 can be the same as the sewing speed of the sewing mechanism 100.

[0065] Thus, during the correction process, the second motor 32232 can drive the correction wheel 32221 to rotate according to the sewing speed of the sewing mechanism 100, so as to achieve the coordinated operation of the correction mechanism 300 and the sewing mechanism 100 while correcting the fabric deviation.

[0066] Furthermore, the rotation speed of the correction wheel 32221 of this utility model can be asynchronous with the sewing speed of the sewing mechanism 100. That is, the rotation speed of the correction wheel 32221 is a preset rotation speed, which can be less than or greater than the sewing speed of the first fabric 101 and the second fabric 102. The preset rotation speed can also be a speed set according to the circumference length formed by the first fabric 101 and the second fabric 102.

[0067] When the preset rotation speed is less than or greater than the sewing speed of the first fabric 101 and the second fabric 102, that is, when there is a very small speed difference between the rotation speed of the correction wheel 32221 and the sewing speed, the speed can be set by one of them being faster and the other slower. Through the coordinated operation of the correction mechanism 300 and the sewing mechanism 100, the correction effect on the sleeve can be achieved at the same time as the control effect of the sewing mechanism 100 during sewing.

[0068] In detail, when the preset rotation speed is less than the sewing speed of the first fabric 101 and the second fabric 102, the sewing speed of the sewing mechanism 100 can be fast, and the rotation speed of the correction wheel 32221 can be slow, thus achieving the effect of pulling the fabric closer. When the preset rotation speed is greater than the sewing speed of the first fabric 101 and the second fabric 102, the sewing speed of the sewing mechanism 100 can be slow, and the rotation speed of the correction wheel 32221 can be fast, thus achieving the effect of loosening the fabric. In turn, through the coordinated operation of the correction mechanism 300 and the sewing mechanism 100, the correction effect of the sleeve can be achieved while controlling the position of the sewing mechanism 100 during sewing.

[0069] When the preset rotation speed is a speed set according to the segmented length of the circumference formed by the first fabric 101 and the second fabric 102, that is, when the rotation speed of the correction wheel 32221 is a speed set according to the segmented length of the circumference formed by the first fabric 101 and the second fabric 102, the length of each segment on the circumference formed by the first fabric 101 and the second fabric 102 can be different, and the rotation speed of the correction wheel 32221 corresponding to any segment can be set by the user according to their needs.

[0070] In other words, at this time, the rotation speed of the correction wheel 32221 corresponding to any segment of fabric on the circumference of the sleeve can be the same as the sewing speed of the sewing mechanism 100. The correction wheel 32221 is driven to rotate according to the sewing speed of the sewing mechanism 100, thus achieving coordinated operation between the correction mechanism 300 and the sewing mechanism 100 while correcting the fabric deviation. Alternatively, the rotation speed of the correction wheel 32221 corresponding to any segment of fabric on the circumference of the sleeve can also be different from the sewing speed of the sewing mechanism 100. This also achieves the effect of correcting the sleeve deviation while controlling the positioning of the sewing mechanism 100 during sewing.

[0071] In one embodiment, the sleeve circumference can be divided into 8 segments, each segment having a different length. The rotation speed of the correction wheel 32221 corresponding to any segment can be different and can be adjusted in real time. At this time, the rotation speed of the correction wheel 32221 corresponding to any segment of fabric on the sleeve circumference can be the same as or different from the sewing speed of the sewing mechanism 100. This can achieve the correction effect on the sleeve while controlling the position of the sewing mechanism 100 during sewing.

[0072] Thus, during the correction process, the second motor 32232 can also drive the correction wheel 32221 to rotate according to the preset rotation speed, which can achieve the correction effect on the sleeve and at the same time achieve the effect of controlling the position of the sewing mechanism 100 during sewing.

[0073] Please see Figure 4 In some cases, the drive assembly 3223 also includes a first cylinder 32233 connected to the correction wheel 32221. The first cylinder 32233 is used to drive the correction wheel 32221 to move closer to the first correction assembly 3221 along the second direction to clamp the second fabric 102.

[0074] Specifically, the second direction can be as follows: Figure 4 The direction shown is A2.

[0075] That is, after the feeding process is completed, the correction mechanism 300 of this utility model can move the correction wheel 32221 in a straight line along the A2 direction under the drive of the first cylinder 32233. At this time, the fabric will be pressed between the correction wheel 32221 and the first correction component 3221.

[0076] Please see Figure 4 In some cases, the second correction assembly 3222 also includes a transmission component 32222. One end of the transmission component 32222 is connected to the first motor 32231, and the other end is connected to the correction wheel 32221. The first motor 32231 drives the transmission component 32222 to rotate, causing the transmission component 32222 to drive the correction wheel 32221 to move back and forth along a first direction to correct the edge position of the second fabric 102.

[0077] Specifically, for example, the transmission component 32222 may include a gear and a rack. The gear meshes with the rack. The first end of the gear can be connected to the first motor 32231, and the second end of the gear can be connected to the correction wheel 32221. This allows the first motor 32231 to drive the correction wheel 32221 to move back and forth along the first direction through the transmission action of the gear and rack, so as to correct the edge position of the second fabric 102.

[0078] In other embodiments of this utility model, the transmission component 32222 may also be a component composed of a lead screw or a connecting rod, and there is no limitation on this.

[0079] In some cases, the position detection device 310 is a photoelectric sensor. The photoelectric sensor can emit a light spot to the preset position 301 of the first correction component 3221. When the light spot illuminates the preset position 301, if the second fabric 102 is detected to be at the preset position 301, a second detection signal can be returned indicating that the second fabric 102 does not need correction; if the second fabric 102 is detected to be outside the preset position 301, a second detection signal indicating that the second fabric 102 needs correction can be returned, thereby controlling the correction device 320 to start the correction process.

[0080] Please see Figure 8In some cases, the drive assembly 3223 of this invention also includes a second cylinder 32234. The second cylinder 32234 is connected to the first correction assembly 3221 and is used to drive the first correction assembly 3221 to extend along a first direction to approach the second tension bar 222, so that the first correction assembly 3221 is located adjacent to the second tension bar 222 to receive the detection signal from the position detection device 310.

[0081] Specifically, in one embodiment, the second cylinder 32234 can drive the first correction component 3221 to extend a certain distance along the B1 direction, directly bringing the first correction component 3221 closer to the set position area of ​​the second tensioning rod 222, thus placing the first correction component 3221 at an adjacent position to the second tensioning rod 222. In another embodiment, the second cylinder 32234 can drive the first correction component 3221 to extend a certain distance along the B1 direction. If the extended end of the first correction component 3221 exceeds the set position area near the second tensioning rod 222, it can also be driven to retract a certain distance along the B2 direction, thereby ensuring that the position of the first correction component 3221 is accurately located in the set position area near the second tensioning rod 222, placing the first correction component 3221 at an adjacent position to the second tensioning rod 222.

[0082] Please refer to Figures 9 to 11 In some cases, the second fabric 102 may include one or more bone positions. The boning mechanism 400 includes a bone-finding detection device 410 and a boning device 420. The bone-finding detection device 410 is electrically connected to the boning device 420. The boning device 420 is used to press and tilt one bone position of the second fabric 102 after activation to complete the boning process. The bone-finding detection device 410 is used to locate bone positions on the second fabric 102 before the sewing mechanism 100 sews the first fabric 101 and the second fabric 102 together, and sends a boning signal to the boning device 420 when two or more bone positions are found. The boning device 420 is used to press and tilt two or more bone positions in the same direction according to the boning signal to complete the boning process.

[0083] Specifically, the first fabric 101 can be cuff ribbing, and the second fabric 102 can be the sleeve. This invention uses a tensioning and rotating mechanism 200 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 200 can clamp the cuff ribbing and sleeve together using a first tensioning rod 221 and a second tensioning rod 222. During sewing, the first tensioning rod 221 and / or the second tensioning rod 222 on the tensioning and rotating mechanism 200 can rotate in conjunction with the operating speed of the sewing mechanism 100, thereby controlling the stable position of the cuff ribbing and sleeve during sewing and preventing fabric shifting during the sewing process.

[0084] The bone-finding detection device 410 of the boning mechanism 400 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.

[0085] 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 invention uses a distance sensor to detect the fabric thickness, thereby determining the location of the seam. By setting a seam threshold in the distance sensor, it outputs a seam detection signal, thus identifying the seam. Therefore, when a single piece of second fabric 102 is folded in half and then overlapped and sewn to form a sleeve, one relatively thick seam is formed; when multiple pieces of second fabric 102 are sewn together in pairs to form sleeves, multiple relatively thick seams are formed.

[0086] On the one hand, when there is only one bone position on the second fabric 102 after sewing, the bone-finding detection device 410 does not need to be started at this time. The bone-reversing device 420 of the bone-reversing mechanism 400 can press and tilt the bone position on the second fabric 102 corresponding to the sewing point between the first fabric 101 and the second fabric 102 after starting, so as to complete the bone-reversing process.

[0087] On the other hand, when there are multiple bone positions in the sewn second fabric 102, the bone-finding detection device 410 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 420, so that the bone-reversing device 420 can press and tilt the two or more bone positions in the same direction according to the bone-reversing signal sent by the bone-finding detection device 410 to complete the bone-reversing process.

[0088] Among them, a single bone position of the second fabric 102 can be as follows: Figure 9 The single strip shown extends from the first end to the second end of the second fabric 102. Figure 9 The second fabric 102 may have two strips, M1 and M2, with the bone positions of M1 and M2 having different orientations.

[0089] The position of the bone structure when pressing down the bone structure of the second fabric 102 can be as follows: Figure 9 The small area indicated by the arrow. That is, the bone position pressing position of this utility model is located at the bone position within a small area corresponding to the required seam connection between the first fabric 101 and the second fabric 102. 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 101 and the second fabric 102.

[0090] Thus, the boning mechanism 400 of this utility model includes a boning detection device 410 and a boning device 420, which can automatically press down sleeves with one or more boning positions, meet the requirements of factories for boning process when sewing cuff ribbing, and improve boning efficiency.

[0091] Please see Figure 12 In some embodiments, the bone-finding detection device 410 includes a second signal transmitting module 411 and a second signal receiving module 412. The second signal receiving module 412 is electrically connected to the bone-reversing device 420. The second signal transmitting module 411 is used to transmit bone position detection signals. The second signal receiving module 412 is used to receive the bone-reversing signals returned by the bone positions through the second fabric 102, and send the bone-reversing signals to the bone-reversing device 420, so that the bone-reversing device 420 presses and tilts two or more bone positions in the same direction according to the bone-reversing signals, thus completing the bone-reversing process.

[0092] Specifically, the bone position detection signal refers to the detection signal that has not been returned by the second fabric 102. The reverse bone signal refers to the detection signal that has been returned by the second fabric 102.

[0093] The bone position detection signal can be a laser signal or other signals, and there are no restrictions on this. For example, when the bone-finding detection device 410 is a laser distance sensor, the bone position detection signal is a laser signal, and the bone-reflection signal is the returned laser signal.

[0094] Understandably, the signal transmission angle of the second signal transmitting module 411 and the signal receiving angle of the second signal receiving module 412 in the bone-finding detection device 410 of this utility model can remain fixed. When the bone-finding detection device 410 is started, at least one of the first tensioning rod 221 and the second tensioning rod 222 of the tensioning and rotating mechanism 200 of the sleeve consisting of the first fabric 101 and the second fabric 102 can be started to rotate simultaneously, so that the sleeve changes position with the tensioning part 220 to correspond to the bone position detection signal emitted by the bone-finding detection device 410, so that the sleeve can sequentially pass through the bone position detection signal for bone-finding detection, realizing that the bone-finding detection device 410 can detect the presence of bone positions in real time and comprehensively at the corresponding parts of the second fabric 102.

[0095] The bone-tilting device 420 compresses 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 420. For example... Figure 11 As shown, the direction of pressing and tilting during the bone-reversing process can be as follows: Figure 11 The direction A1 is shown.

[0096] Thus, the bone-finding detection device 410 of this utility model can detect in real time whether there are two or more bone positions in the sewn second fabric 102, and then send a bone-removing signal to the bone-removing device 420 in a timely manner, so that the bone-removing device 420 can remove bone from two or more bone positions and complete the bone-removing process.

[0097] Please see Figure 9 and Figure 13 In some embodiments, the bone-finding detection device 410 further includes a bone position marking module 413, which is electrically connected to the sewing mechanism 100. The bone position marking module 413 is used to mark two or more bone positions and send marking signals to the sewing mechanism 100. The marking signals can be voltage signals or current signals, and there is no limitation on this.

[0098] like Figure 9 As shown, when there are four skeletal positions, the skeletal positions include the initial skeletal position M1 and the terminal skeletal position M2. In this case, the initial skeletal position M1 is the second skeletal position after the first skeletal position. Please refer to [link / reference]. Figure 13 The sewing mechanism 100 includes a sewing component 110, a sewing presser foot 120, and a presser foot control component 130. The sewing component 110 is connected to the sewing presser foot 120. A bone position marking module 413 is electrically connected to the first end of the presser foot control component 130, and the second end of the presser foot control component 130 is electrically connected to both the sewing component 110 and the sewing presser foot 120. The presser foot control component 130 controls the sewing component 110 and the sewing presser foot 120 to continue sewing operations according to the marking signal until a first distance d1 is separated from the end bone position M2, stopping the sewing component 110 and the sewing presser foot 120 at the first distance d1 from the end bone position M2, and controlling the sewing presser foot 120 and the sewing component 110 to rise to a preset height. The sewing component 110 of this invention may include sewing operation parts such as a sewing needle.

[0099] Understandably, if the bone-finding detection device 410 detects two bone positions on the second fabric 102, the presser foot control component 130 can control the sewing component 110 to continue sewing operations according to the marking signal until it reaches a first distance d1 away from the end bone position M2, so that the sewing presser foot 120 stops at a first distance d1 away from the end bone position M2, and controls the sewing presser foot 120 to be raised to a preset height h, forming the raised posture of the sewing presser foot 120.

[0100] Wherein, the first distance d1 is the distance between the center projection point obtained by the orthographic projection of the sewing presser foot 120 on the horizontal plane where the second fabric 102 is located and the end bone position M2. The preset height h is the vertical height between the lowest point of the sewing presser foot 120 and the horizontal plane where the second fabric 102 is located.

[0101] That is, before the bone-removing device 420 is activated, the bone-finding detection device 410 of this utility model can mark the specific sewing positions of two or more bone positions, thereby obtaining a marking signal, and sending the marking signal to the sewing mechanism 100, so that the presser foot control component 130 of the sewing mechanism 100 first raises the sewing presser foot 120 to a first distance d1 and a preset height h from the end bone position M2, so as not to hinder the subsequent bone-removing device 420 from removing bone from two or more bone positions.

[0102] Furthermore, after the process of debossing the bone positions on the second fabric 102 using the debossing device 420 is completed, the sewing mechanism 100 can then lower the sewing component 110 and the sewing presser foot 120 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 102, the sewing mechanism 100 can continue to sew the required seam positions after the debossed positions of the first fabric 101 and the second fabric 102 to complete the sewn product.

[0103] In some cases, the bob-reversing device 420 is electrically connected to the presser foot control component 130. The bob-reversing device 420 is used to start working after the presser foot control component 130 controls the sewing component 110 and the sewing presser foot 120 to stop at a first distance d1 from the end bob position M2 and controls the sewing component 110 and the sewing presser foot 120 to be raised to a preset height h.

[0104] That is, before the sewing mechanism 100 sews the first fabric 101 and the second fabric 102, the boning mechanism 400 of this utility model can control the sewing component 110 and the sewing presser foot 120 to stop at a first distance d1 from the end bone position M2, and control the sewing component 110 and the sewing presser foot 120 to raise a preset height h, so as to ensure that there is enough space for boning operation, and then let the boning device 420 start to work to carry out the boning process, thus ensuring the efficiency of boning.

[0105] Please see Figure 11 In some embodiments, the bone-tilting device 420 includes a bone-tilting component 421 and a driving component 422. The driving component 422 is connected to the bone-tilting component 421 and is used to lock the position of the bone according to the bone-tilting signal, drive the bone-tilting component 421 to descend vertically to a position region parallel to the bone position at a second distance d2, and move horizontally along a third direction to tilt the bone position in the third direction.

[0106] The sewing mechanism 100 includes a sewing component 110, a sewing presser foot 120, and a presser foot control component 130. The presser foot control component 130 is electrically connected to the sewing component 110 and the sewing presser foot 120 respectively. The presser foot control component 130 is also electrically connected to the drive component 422. After receiving the end-of-work signal from the drive component 422, the presser foot control component 130 controls the sewing component 110 and the sewing presser foot 120 to descend vertically to sew the tilted bone.

[0107] Specifically, the end-of-work signal refers to the electrical signal emitted by the drive component 422 that indicates all detected bone positions have completed tilting in a third direction. The tilting component 421 can be as follows: Figure 11 The inverted bone pick shown.

[0108] The boning device 420 of this invention tilts all bone positions in a third direction through the boning component 421. Even if the bone positions tilt in the same direction, the tilting direction is more uniform, resulting in a higher success rate for subsequent sewing of the bone positions by the sewing component 110 and sewing presser foot 120. Figure 9 In this context, the third direction can be the A2 direction.

[0109] Thus, after receiving the end-of-work signal from the drive component 422, the presser foot control component 130 of this utility model can control the sewing component 110 and the sewing presser foot 120 to descend vertically to sew the tilted bone position, thereby realizing the complete bone tilting process.

[0110] Please see Figure 11 In some embodiments, the bone-setting device 420 further includes an air-blowing component 423. The air-blowing component 423 is connected to the drive component 422 and is used to start working simultaneously upon receiving a start signal from the drive component 422, and to blow air in a third direction to assist in bone setting and prevent the bone from rebounding after being pressed and tilted.

[0111] That is, the bone-setting device 420 of this utility model can also be provided with an air-blowing component 423. The air-blowing component 423 may include components such as an air-blowing port, a small air pump, and an air-transmitting pipe 4231. The small air pump and the air-transmitting pipe 4231 accurately blow air from the air-blowing port to the third 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 stitching. The air-transmitting pipe 4231 can be hook-shaped or other shapes, without limitation. The air-transmitting pipe 4231 can be made of rigid materials such as stainless steel or soft materials such as silicone, without limitation.

[0112] The air blowing component 423 can be set to start when the drive component 422 is started, or to stop when the drive component 422 is stopped, that is, it can work synchronously and stop working.

[0113] In other embodiments of this utility model, the air blowing component 423 can also be set to start with the start of the drive component 422 and continue to work until the sewing component 110 and the sewing presser foot 120 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 423 is more flexible.

[0114] Please see Figure 11 In some embodiments, the drive component 422 includes a third cylinder 4221 and a fourth cylinder 4222. The third cylinder 4221 is used to drive the reverse bone component 421 to descend vertically to a parallel position region at a second distance d2 from the bone position. The fourth cylinder 4222 is used to drive the reverse bone component 421 to move horizontally in a third direction.

[0115] That is, in the reverse bone mechanism 400 of this utility model, the reverse bone component 421 can be driven by two cylinders to move in the vertical direction (i.e., C1 direction and C2 direction) and in the horizontal direction (i.e., A1 direction and A2 direction) respectively, so as to realize the tilting and pressing effect of the reverse bone component 421 on the bone position.

[0116] In detail, after the material loading process is completed, the sewing mechanism 100 starts operating. At this time, driven by the third cylinder 4221, the bobbin component 421 can descend along the C2 direction. Subsequently, pushed by the fourth cylinder 4222, the bobbin component 421 can move along the negative X-axis direction, causing the bone position to... Figure 9 The third side shown is tilted in the direction of A2.

[0117] At the same time, when the tilting component 421 causes the bone to tilt in a third direction, the blowing component 423 can also be activated to prevent the tilted bone from rebounding.

[0118] In some cases, the reverse bone component 421 is in the form of a metal sheet, and the reverse bone component 421 contacts the reverse bone surface where the bone is located to tilt the bone to a third direction.

[0119] That is, the reverse bone component 421 of this utility model 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, which is not limited here.

[0120] Thus, this utility model can use the metal sheet-shaped inverted bone component 421 to press down on the bone, causing the bone to tilt in a third direction.

[0121] Please see Figure 10 In some embodiments, the bone-setting mechanism 400 further includes a bone-finding support 430. The bone-finding detection device 410 is mounted and fixed on the bone-finding support 430, which is set at a preset angle to the horizontal plane toward the second fabric 102, so that the bone-finding detection device 410 can transmit a bone position detection signal to the second fabric 102 and receive the bone-setting signal returned from the bone position.

[0122] Specifically, the osteopathic support 430 can be a metal sheet or plate set at a preset angle to the horizontal plane, such as... Figure 10 As shown, the bone-finding support 430 can also be two integrated metal sheets or plates at a preset angle, and there are no restrictions here.

[0123] The preset angle α can be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, and there are no restrictions here.

[0124] The bone-finding detection device 410 is mounted and fixed on the bone-finding bracket 430, meaning that the bone-finding bracket 430 is provided with at least one screw hole, and the bone-finding detection device 410 can be mounted and fixed together with the screw hole on the bone-finding bracket 430 by screws or bolts.

[0125] In other embodiments of this utility model, the bone-finding detection device 410 is installed and fixed on the bone-finding bracket 430 in other ways, which are not limited here.

[0126] Thus, the bone-setting mechanism 400 of this utility model can support the bone-finding detection device 410 through the bone-finding bracket 430, so that the bone-finding detection device 410 can normally transmit bone position detection signals to the second fabric 102 and receive bone-setting signals.

[0127] In addition, the sewing equipment 1000 of this utility model can be used to realize the following processing operation: First, the cuff ribbing (first fabric 101) is manually placed onto the tensioning and rotating mechanism 200. After the cuff ribbing is stretched open, it is positioned using corresponding mechanical parts on the sewing machine 1000 to ensure that the cuff ribbing does not shift during subsequent sewing. During this process, it is crucial to ensure that the ribbed part of the cuff ribbing is to the right of the presser foot 120 (in some cases, this can be the A1 direction) when manually placing the cuff ribbing.

[0128] After the cuff ribbing is fully stretched, the cuff (second fabric 102) is manually slipped over the cuff ribbing (ensuring the cuff's ribbed area aligns with the ribbing's ribbed area during slip-on). After slip-on, the fabric is pressed down by the holding part 230, the sleeve body fabric is corrected by the straightening mechanism 300, and the cuff is straightened by the boning mechanism 400, until the sewing process is finally completed. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to the embodiments of the present invention without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
