In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0038] See also Figure 1 The present invention provides a knitting method 10 with low production cost, high yield rate and good product modeling. For further information, please refer to Figure 4 The system used in the knitting method 10 includes a data acquisition module 310 for identifying the graphics or instructions of the knitting pattern 20; a control module 330 for storing the pattern data and controlling the knitting path of the knitting needle 320; a driving module 340 connected to the control module 330, for driving the knitting needle 320 to move under the control of the control module 330; and a state monitoring module 350 for obtaining the current working state of the knitting needle 320 and feeding back the state data to the control module 330. It should be noted that the woven piece here can also be understood as a target knitted sweater piece. In other embodiments, the woven piece and the target knitted sweater piece are both used to refer to the knitted piece after knitting.

[0039] See also Figure 2 and Figure 3 The knitting paper pattern 20 used in the knitting method 10 of the present invention includes a front placket 210 connected in an integral manner, a left sleeve piece 220 and a right sleeve piece 230 respectively connected to both sides of the front placket 210, a rear shoulder piece 240 connecting the left sleeve piece 220 and the right sleeve piece 230 and corresponding to the front placket 210, and a neckline 250 respectively adjacent to the front placket 210, the left sleeve piece 220, the right sleeve piece 230 and the rear shoulder piece 240, and the front placket 210 is a whole piece structure or includes a first placket 211 connected to the left sleeve piece 220 and a second placket 212 connected to the right sleeve piece 230. When the knitting needle 320 paper pattern of the front placket 210 as a whole piece structure is used, the knitted sweater obtained by splicing and sewing is a pullover, and when the front placket 210 is a split first placket 211 and a second placket 212, the knitted sweater obtained by splicing and sewing is a cardigan.

[0040] Please refer again Figure 1 The knitting method 10 of the present invention comprises the following steps:

[0041] S1) The data acquisition module 310 acquires the graphics or instructions of the knitted paper pattern 20 to form paper pattern information.

[0042] Specifically, the data acquisition module 310 can not only obtain the 1:1 scale graphic information of the knitting needle 320 paper pattern and send the graphic information to the control module 330, but also obtain the digital instructions associated with the knitted paper pattern 20 and send the digital instructions to the control module 330. The control module 330 performs uniform transcoding processing on the graphic information or digital instructions to form a digital signal.

[0043] S2) The control module 330 receives the paper pattern information sent by the data acquisition module 310, determines the knitting type according to the paper pattern information, defines the knitting starting position, knitting direction, knitting point position and stitching path under different knitting types, and encodes each knitting point on the paper pattern.

[0044] Specifically, the control module 330 compares the graphic information sent by the data acquisition module 310 with the paper pattern type pre-stored in the control module 330 to determine the knitting type, and designs a corresponding knitting path according to the knitting type. In one embodiment, the knitting type includes cardigan knitting and pullover knitting. When the knitting type is cardigan knitting, the shape of the knitted paper pattern 20 is as follows: Figure 3 As shown, in this case, the control module 330 controls the driving module 340 to adjust the knitting needle 320 to knit the knitting thread in a V-shaped path, and the knitting starting position starts from the first flap 211 or the second flap 212 of the knitting paper pattern 20. The knitting route reference Figure 3 When the knitting type is pullover knitting, the shape of the knitted paper pattern 20 is as follows: Figure 2 As shown, in this case, the control module 330 controls the driving module 340 to adjust the knitting needle 320 to knit the yarn in a horizontal path or a vertical path; the knitting starting position can start from any one of the front placket 210, the left sleeve piece 220, the right sleeve piece 230 and the back shoulder piece 240, and the knitting route reference Figure 2 The direction of the arrowed line a.

[0045] Further, in step S2, the coding information of each knitting point includes the coordinate parameters of the knitting point and the deflection angle of the knitting needle 320. That is, whenever the knitting needle 320 knits to a knitting point position, the driving module 340 adjusts the deflection angle of the knitting needle 320 under the action of the control module 330, such as knitting in the same direction or in the reverse direction.

[0046] In one embodiment, the position of each knitting point is determined by the pattern shape, yarn size, target knitting density, knitting pattern, etc. When the knitting point position and the deflection angle of the knitting needle 320 are determined, the knitting needle 320 performs a knitting action at each knitting point under the control of the driving module 340, thereby forming a knitted piece.

[0047] S3) The control module 330 sends instructions to the driving module 340 to drive the knitting needle 320 to weave a snake-shaped pattern along a V-shaped path or to weave a cross-shaped pattern along a horizontal path or a vertical path.

[0048] For details, please refer to Figure 3 When the knitting type is cardigan knitting, the knitting needle 320 starts from the second flap 212 of the knitting paper pattern 20, and knits the right sleeve piece 230, the back shoulder piece 240 and the left sleeve piece 220 in sequence, and finally knits to the first flap 211, and the knitting operation of the fabric piece is completed from the end of the first flap 211; it can also start from the first flap 211 and knit to the second flap 212 in reverse order. In another embodiment, please refer to Figure 2When the knitting type is pullover knitting, the knitting needle 320 starts from the front flap 210 of the knitted paper pattern 20. When knitting to the connection between the front flap 210 and the left sleeve 220 and the right sleeve 230, the knitting needle 320 knits back and forth between the left sleeve 220 and the right sleeve 230. After completing the knitting operation of the left sleeve 220 and the right sleeve 230, the knitting operation of the fabric piece is terminated by the end of the rear shoulder 240. The rear shoulder 240 can also be knitted in reverse order to the front flap 210, thereby realizing the vertical path knitting of the fabric piece. Similarly, the knitting can also start from the left sleeve 220, and after knitting back and forth between the front flap 210 and the rear shoulder 240, the knitting of the right sleeve 230 is started, or the right sleeve 230 is knitted in reverse order to the left sleeve 220, thereby realizing the horizontal path knitting of the fabric piece.

[0049] S4) When the knitting needle 320 moves to the contour boundary position of the target knitted shirt piece or the knitting path direction conversion position, the state monitoring module 350 sends action information to the control module 330, and the control module 330 controls the driving module 340 to adjust the action of the knitting needle 320 until the knitting operation of the target knitted shirt piece is completed.

[0050] It can be understood that the status monitoring module 350 is used to detect the knitting progress of the knitting needle 320, and to warn the control module 330 when the knitting needle 320 reaches the knitting contour position of the knitted paper pattern 20, so that the control module 330 can control the driving module 340 to adjust the knitting parameters of the knitting needle 320; or after the knitting action is completed, the knitting state of the knitting needle 320 is fed back to the control module 330, and the control module 330 controls the driving module 340 to stop the output, that is, stop the knitting action of the knitting needle 320.

[0051] It should be noted that after the target knitted sweater pieces are knitted, the target knitted sweater pieces can be overlapped along the sleeve width center line of the target knitted sweater pieces to form two seams and sew the seams to obtain a knitted sweater. In actual production, according to production conditions, the target knitted sweater pieces can be overlapped manually to form seams, and then the seams can be sewed by a sew mechanism, or a manipulator controlled by a control module 330 and developed externally or on the knitting device 30 can be used to complete the overlapping operation of the target knitted sweater pieces, and the sew mechanism is used as a part of the entire knitting device 30, and is controlled and called by the control module 330 to realize the automated production of knitted sweaters.

[0052] In the process of superimposing the target knitted sweater pieces, it is necessary to define the sleeve center line of the target knitted sweater pieces, that is, the center line of the left sleeve piece 220 and the center line of the right sleeve piece 230 of the knitted paper pattern 20. Depending on the knitting type, when it is a cardigan knitting, the center line connection can refer to Figure 3 The dotted line d refers to the arrow curve f in the overlap direction; when knitting a pullover, the center line can refer to Figure 2The middle dotted line c, the overlap direction refers to the arrow curve e. Then, along the position and direction of the center line of the sleeve width, the target knitted sweater piece is folded, so that a seam is formed at the connection position between the left sleeve width and the hem of the target knitted sweater piece and the connection position between the right sleeve width and the hem, and the seams are sewn to obtain the following Figure 5 or Figure 6 The sweater shown, Figure 5 The seam g and Figure 6 The seam h shown in FIG. 1 is the seam of the present embodiment.

[0053] The present invention also discloses a knitting device 30, which includes a knitting paper pattern 20, a data acquisition module 310, a control module 330, a knitting needle 320, a driving module 340 and a status monitoring module 350, wherein the knitting paper pattern 20 includes an integrally connected front lapel 210, a left sleeve piece 220 and a right sleeve piece 230 respectively connected to the two sides of the front lapel 210, a rear shoulder piece 240 connecting the left sleeve piece 220 and the right sleeve piece 230 and corresponding to the front lapel 210, and a neckline 250 respectively adjacent to the front lapel 210, the left sleeve piece 220, the right sleeve piece 230 and the rear shoulder piece 240, the front lapel 210 is a whole piece structure or includes a first lapel piece 211 connected to the left sleeve piece 220 and a second lapel piece 212 connected to the right sleeve piece 230. When the front placket 210 of the paper pattern of the knitting needle 320 is a whole piece structure, the knitted sweater obtained by sewing together is a pullover; when the front placket 210 of the paper pattern of the knitting needle 320 is a split first placket 211 and a second placket 212, the knitted sweater obtained by sewing together is a cardigan.

[0054] The data acquisition module 310 is used to identify the graphics or instructions of the knitted paper pattern 20, and includes an image acquisition unit and a digital model acquisition unit. In one embodiment, the data acquisition module 310 obtains the graphic content of the knitted paper pattern 20 through software or obtains the instructions of the knitted paper pattern 20 through a drawing plug-in. For example, the data acquisition module 310 can include input software with a drawing plug-in for obtaining the knitted paper pattern 20, such as loading a tablet computer capable of drawing graphics on the control module 330, so that the graphics or instructions of the knitted paper pattern 20 can be transmitted to the control module 330 through the input of the drawing instruction, and the operator can perform the next process for production according to the input knitted paper pattern 20 graphics or instructions.

[0055] The control module 330 is used to receive the paper pattern information transmitted by the data module, determine the knitting type according to the paper pattern information, define the knitting starting position, knitting direction, knitting point position and stitching path under different knitting types, and model the knitting points.

[0056] In one embodiment, the control module 330 is preset with an information conversion plug-in, which can convert the received graphic information or digital information of the knitted paper pattern 20 into digital coordinate information, so as to facilitate modeling of the knitting points associated with the knitted paper pattern 20.

[0057] In one embodiment, the knitting type includes cardigan knitting and pullover knitting. When the knitting type is cardigan knitting, a V-shaped path knitting yarn is used. When the knitting type is pullover knitting, a horizontal path or a vertical path knitting yarn is used. Specifically, when the V-shaped path knitting yarn is used, the knitting starting position starts from the first flap 211 or the second flap 212 of the knitting paper pattern 20. The knitting line reference Figure 3 When the horizontal or vertical path is used to weave the yarn, the knitting starting position can be any one of the front flap 210, the left sleeve 220, the right sleeve 230 and the back shoulder 240. The knitting line reference Figure 2 The direction of curve a with an arrow.

[0058] Further, in one embodiment, the modeling information of the knitting point includes the coordinate parameters of each knitting point and the deflection angle of the knitting needle 320. That is, whenever the knitting needle 320 knits to a knitting point position, the driving module 340 adjusts the deflection angle of the knitting needle 320 under the action of the control module 330, such as knitting in the same direction or in the reverse direction. The position of each knitting point is determined by parameters such as the shape of the paper pattern, the size of the knitting thread, the knitting density of the target knitted sweater piece, and the knitting pattern. When the knitting point position and the deflection angle of the knitting needle 320 are determined, the knitting needle 320 performs the knitting action at each knitting point under the control of the driving module 340, thereby forming a knitted piece.

[0059] The knitting needle 320 is used to thread the knitting thread and perform a specified knitting action, which includes knitting a snake-shaped pattern along a V-shaped path or knitting a cross-shaped pattern along a horizontal path or a vertical path. It should be noted that the knitting device 30 of this embodiment also includes a machine table for placing the formed fabric and providing a working platform for the knitting operation, and of course, also includes a chassis for storing and encapsulating each module for protection.

[0060] The driving module 340 is connected to the control module 330, and is used to drive and adjust the knitting path of the knitting needle 320 under the action of the control module 330 to knit an integrated shirt piece, that is, a target knitted shirt piece. In one embodiment, the driving module 340 includes two machine plate slide rails, so that the control module 330 can adjust the position of the knitting needle 320 by controlling the two machine plate slide rails. Of course, other driving devices can also be used to replace the driving module 340 of this embodiment, which will not be repeated here.

[0061] The state monitoring module 350 is used to obtain the current working state of the knitting needle 320 and feed back the state data to the control module 330, and the control module 330 feeds back and adjusts the action of the driving module 340. In one embodiment, the state monitoring module 350 can warn the control module 330 when the knitting needle 320 reaches the knitting contour position of the knitting paper pattern 20 during the knitting process of the knitting needle 320, so that the control module 330 controls the driving module 340 to adjust the knitting parameters of the knitting needle 320 and correct the erroneous action of the knitting needle 320; and after the knitting action is completed, the knitting state of the knitting needle 320 can be fed back to the control module 330, and the control module 330 controls the driving module 340 to stop output, that is, stop the knitting action of the knitting needle 320. It should be noted that the monitoring process of the knitting needle 320 by the state monitoring module 350 can be carried out in real time or according to a certain period, such as sending the state information of the knitting needle 320 to the control module 330 every second, which can be determined according to production conditions.

[0062] In one embodiment, after the target knitted sweater pieces are knitted, they are overlapped and sewn to obtain a knitted sweater. The sewing operation of the target knitted sweater pieces can be controlled and adjusted by the control module 330, or can be controlled by an external control device. The overlapping operation of the target knitted sweater pieces can be performed by manually overlapping the target knitted sweater pieces and forming a seam, or by using a manipulator controlled by the control module 330 that is externally connected or developed on the knitting device 30 to complete the overlapping operation of the target knitted sweater pieces, so as to realize the automated production of the knitted sweater.

[0063] In the process of overlapping the target knitted sweater pieces, it is necessary to define the sleeve center line of the target knitted sweater pieces, that is, the center line of the left sleeve piece 220 and the center line of the right sleeve piece 230 of the knitted paper pattern 20. Depending on the knitting type, when knitting a pullover, the center line connection can refer to Figure 3 The dotted line d, the overlap direction refers to the arrow curve f; when knitting a cardigan, the center line can refer to Figure 2 The middle dotted line c, the overlap direction refers to the arrow curve e. Then, the target knitted sweater piece is folded along the position and direction of the center line of the sleeve. In this way, a seam is formed at the connection position between the left sleeve and the hem of the target knitted sweater piece and at the connection position between the right sleeve and the hem, and the seams are sewn to obtain the following: Figure 5 or Figure 6 The sweater shown, Figure 5 The seam g and Figure 6 The seam h shown in FIG. 1 is the seam of the present embodiment.

[0064] The knitting method 10 and the knitting device 30 of the present invention are implemented, and a knitting paper pattern 20 of an integrated structure is adopted. The control module 330 judges the knitting type according to the paper pattern structure, and defines and establishes the knitting parameters and the knitting point model associated with the knitting paper pattern 20. Then, the driving module 340 is controlled to drive the knitting needle 320 to operate in a predetermined knitting path according to the knitting parameters and the knitting point model data, so as to obtain a target knitted sweater piece with the same shape as the knitted paper pattern 20. In this way, after the target knitted sweater pieces are overlapped, only a seam is formed between the left sleeve and the front and back hems of the sweater body and between the right sleeve and the front and back hems of the sweater body, and the number of seams is reduced to two, which reduces the processing difficulty of the sweater, and is less likely to cause problems such as wrong sewing of the sewn pieces, thereby effectively improving the yield rate of the sweater; while the number of seams is reduced, the number of yarn losses at the seams is simultaneously reduced, thereby reducing the production cost of the sweater; the seams are arranged at the bottom of the left and right sleeves, which is convenient for setting patterns or shapes at multiple positions on the sweater, thereby expanding the shapeable area on the sweater, which is conducive to improving the market competitiveness of the product.
