[0036] The present inventors find that the hosiery machines with automatic toe sewing function on the market are divided into two types of blind sewing and opposite eye sewing according to the differences of toe sewing mechanical mechanisms. The opposite eye sewing method is to sew the line holes of the front and back sock pieces after folding the sock, which has the advantages of fine and soft sewing line and comfortable wearing on the foot, and the disadvantages of loose sewing and easy breaking and cracking.

[0037] The blind sewing method is to continuously sew without interval after folding the sock without aligning the front and back sock pieces, which has the advantages of tight and dense sewing line and is more suitable for socks such as sports socks and thick socks, and the disadvantages of tight and wide sewing line and uncomfortable wearing.

[0038] To solve the above problems, the present application provides a toe sewing control method, a computer device and a sewing device.

[0039] Please refer to Figure 1 、 Figures 8 to 10 , Figure 1 is a schematic block diagram of the toe sewing control method provided by the present application; Figure 8 is a schematic diagram of the same direction sewing of the first sewing line L1 and the second sewing line L2 provided by the present application; Figure 9 is a schematic diagram of the reverse sewing of the first sewing line L1 and the second sewing line L2 provided by the present application; Figure 10 is a schematic diagram of odd sewing, even sewing and all sewing provided by the present application.

[0040] The toe sewing control method provided by the present application can include the following steps:

[0041] S1: adopt the opposite eye sewing method to perform the first sewing line L1 along the sewing route 101.

[0042] Specifically, the sewing route 101 can be understood as a route of the sewing object 100 that needs to be sewn, for example, from one end of two overlapping cloth pieces to the other end. The first sewing line L1 provided in the present application adopts the opposite eyelet sewing mode, thus not causing the problem of foot jamming caused by the width of the line, and the comfort of the product after sewing is high.

[0043] S2: The second sewing line L2 is sewn along the sewing route 101 in the opposite eyelet sewing mode.

[0044] Specifically, the second sewing line L2 adopts the same route as the first sewing line L1, that is, the second sewing line L2 is sewn on the same route, and the second sewing line L2 still adopts the opposite eyelet sewing mode, and the second opposite eyelet sewing is performed on the basis of the first opposite eyelet sewing, which can improve the firmness and durability of the product after sewing, and at the same time, the problem of foot jamming will not occur. Through the two opposite eyelet sewing operations, the technical effect of blind sewing is achieved, and at the same time, the discomfort problem caused by blind sewing is avoided, and the comfort and durability are improved.

[0045] It should be noted here that the second sewing line L2 and the first sewing line L1 are the same route, and are not limited to being sewn in the same direction. For example, on the same sewing route 101, the first sewing line L1 can be sewn from the first end to the second end, and the second sewing line L2 can be sewn from the first end to the second end as shown in Figure 8 , or from the second end to the first end as shown in Figure 9 . Specifically, it can be selected as needed, and the present application does not limit it. In actual operation, the second sewing line L2 adopts the mode of the second end to the first end, which is more convenient, and the sewing object 100 can be directly pushed in the opposite direction of the first sewing line L1 after the first sewing line L1, and the second sewing line L2 is directly performed, without the need for line cutting, re-starting sewing, etc. Operation, which can save the sewing process and time, and improve the sewing efficiency.

[0046] In an embodiment, at least a part of the route of the first sewing line L1 and the second sewing line L2 performed on the same sewing route 101 adopts the needle spacing mode.

[0047] Specifically, at least a part of the route can also be understood as a part of the route of the first sewing line L1 on the same sewing route 101, or a part of the route of the second sewing line L2 on the same sewing route 101, so the needle spacing mode can be either the first sewing line L1 or the second sewing line L2, or both of them adopt the needle spacing mode.

[0048] Please refer to Figure 2 , Figure 2is a schematic block diagram of a step before step S1 of the present application, which is a step of performing a first stitching L1 along a stitching route in a cross-stitch manner.

[0049] In an embodiment, the step before step S1 of performing a first stitching L1 along a stitching route 101 in a cross-stitch manner can comprise:

[0050] S01: in response to receiving a request instruction of performing a first stitching L1 along a stitching route 101.

[0051] Specifically, for example, a control system 30 for controlling the stitching operation receives a request of performing a stitching on a certain stitching object 100, which includes a stitching route 101 of the stitching object 100, the control system 30 can respond to the request instruction and then issue a corresponding control instruction.

[0052] S02: according to the request instruction, obtaining a distance between a first needle and a last needle that the stitching head mechanism 50 needs to move.

[0053] Specifically, the stitching head mechanism 50 is used to move in position during stitching, for example, the distance that each needle needs to move during the stitching process is moved by the stitching head mechanism 50. The distance between the first needle and the last needle can be understood as the total distance that the stitching head mechanism 50 needs to move.

[0054] S03: based on the distance between the first needle and the last needle, obtaining a distance parameter of each movement of the stitching head mechanism 50.

[0055] Specifically, after obtaining the distance between the first needle and the last needle, according to the stitching manner and the width of the stitching pattern and other information contained in the request instruction of the first stitching L1, the distance between each needle for stitching on the stitching object 100 can be obtained, that is, the distance parameter of each movement of the stitching head mechanism 50. It can be understood that the distance parameter of each movement is also the interval distance between each two adjacent stitching holes (not shown in the figure), which is the unit movement distance of the stitching head mechanism 50 in the stitching route 101. By obtaining the distance parameter of each movement of the stitching head mechanism 50, the corresponding position movement can be performed according to the request instruction. For example, if the request instruction indicates that one pulse number is moved each time, then the stitching head mechanism 50 moves one distance parameter of each movement. The pulse number is a common expression in the stitching operation, and one pulse number can be understood as the movement distance of one needle of the stitching head mechanism 50.

[0056] S04: based on the distance parameter of each movement, counting the number of movements of the stitching head mechanism 50 each time the stitching head mechanism 50 moves.

[0057] Specifically, after the distance between the first needle and the last needle and the distance parameter of each movement of the sewing head mechanism 50 are obtained, the total number of movements of the first sewing line L1 in the current sewing route 101 can be obtained by dividing the two. When the sewing head mechanism 50 moves each time, the number of movements can be counted by the counting module 60, such as an optical encoder, and when the number of movements reaches the total number of movements in the current sewing route 101, the result that the first sewing line L1 operation in the current sewing route 101 is completed can be obtained.

[0058] It can be understood that the counting module 60 can be connected with the control system 30 of the sewing operation, which includes a corresponding processor (not shown in the figure). After the number of sewing times is obtained by the counting module 60, the counting result is transmitted to the control system 30, and the corresponding operation instruction is fed back by the control system 30. The sewing head mechanism 50 also needs to be connected with the control system 30, and the control system 30 issues the corresponding operation instruction to the driving assembly 40, such as a motor, to drive the sewing head mechanism 50 to move or stop.

[0059] Please refer to Figure 3 , Figure 3 is a schematic block diagram of the specific embodiment provided by the present application, which is to adopt the skip-needle method to sew at least part of the route of the first sewing line L1 and the second sewing line L2 in the same sewing route.

[0060] In an embodiment, the skip-needle method to sew at least part of the route of the first sewing line L1 and the second sewing line L2 in the same sewing route 101 can include any combination of the following:

[0061] S31: the first sewing line L1 is the skip-needle sewing 10, and the second sewing line L2 is the full sewing 20.

[0062] Specifically, the skip-needle sewing 10 can be understood as having an interval between each needle and the next needle, which is not continuous sewing, and the interval can be one, two or more. The full sewing 20 is continuous from the first needle to each needle, and there is no interval or jump between the sewing needles.

[0063] In a further embodiment, as shown in Figure 10 , the skip-needle sewing 10 can include odd-numbered sewing 11 or even-numbered sewing 12, which are used to sew different position points of the same sewing route 101, such as odd-numbered sewing 11 and even-numbered sewing 12, which are on the same route of the sewing object 100, but sew different position points. The odd-numbered sewing 11 and the even-numbered sewing 12 can be understood as being spaced apart from each other. For example, in the same sewing route 101, the sewing needle sequence of the odd-numbered sewing 11 is: 1, 3, 5, 7, 9, …, and the sewing needle sequence of the even-numbered sewing 12 is: 2, 4, 6, 8, 10, …

[0064] Further, the first time L1 is a needle stitch 10, the second time L2 is all stitches 20 can be any one of the following two stitching methods:

[0065] S311: the first time L1 is an odd number of stitches 11, and the second time L2 is all stitches 20.

[0066] For example, the first time L1 needle sequence is: 1, 3, 5, 7, 9…, the second time L2 needle sequence is 1, 2, 3, 4, 5, 6…, that is, the first time L1 is odd number of stitches 11; the second time L2 is all stitches 20, without needle separation.

[0067] S312: the first time L1 is an even number of stitches 12, and the second time L2 is all stitches 20.

[0068] For example, the first time L1 needle sequence is: 2, 4, 6, 8, 10…, the second time L2 needle sequence is 1, 2, 3, 4, 5, 6…, that is, the first time L1 is even number of stitches 12; the second time L2 is all stitches 20, without needle separation.

[0069] S32: the first time L1 is all stitches 20, and the second time L2 is needle separation stitch 10.

[0070] Specifically, the first time L1 is all stitches 20, without needle separation, and each needle is continuously stitched.

[0071] The second time L2 needle separation stitch 10 can use one of the odd number of stitches 11 or even number of stitches 12, for example, any one of the following steps S321 or S322.

[0072] S321: the first time L1 is all stitches 20, and the second time L2 is odd number of stitches 11.

[0073] S322: the first time L1 is all stitches 20, and the second time L2 is even number of stitches 12.

[0074] Specifically, the specific stitching method of odd number of stitches 11 and even number of stitches 12 is the same as the foregoing, which will not be described here.

[0075] S33: the first time L1 is needle separation stitch 10, and the second time L2 is needle separation stitch 10.

[0076] Specifically, it can be understood that when the first time L1 and the second time L2 are both needle separation stitch 10, the two times of stitching can be the same needle separation method, or the two times of stitching can be different needle separation methods. That is, the step S33 can use any one of the following four methods:

[0077] S331: The first stitch L1 is an odd-numbered stitch (11), and the second stitch L2 is an even-numbered stitch (12).

[0078] S332: The first stitch L1 is an even-numbered stitch (12), and the second stitch L2 is an odd-numbered stitch (11).

[0079] S333: The first stitch L1 is an odd number of stitches, 11; the second stitch L2 is an odd number of stitches, 11.

[0080] S334: The first stitch L1 is an even number of stitches, 12, and the second stitch L2 is an even number of stitches, 12.

[0081] When stitching, any one of S331 to S334 can be used. It can be understood that when the stitch spacing method is the same for the first stitch L1 and the second stitch L2 in steps S333 and S334, only odd or even positions have stitches, and there are still stitch gaps after the stitching is completed. However, in steps S331 and S332, the stitch spacing method is different, that is, a combination of odd stitch 11 and even stitch 12. After the stitching is completed, both odd and even positions have stitches. Therefore, the stitching effect produced when the stitch spacing method of the first stitch L1 and the second stitch L2 is different is better than the stitching effect when the stitch spacing method of the first stitch L1 and the second stitch L2 is the same. That is, the durability of the stitches with odd stitch 11 + even stitch 12 or even stitch 12 + odd stitch 11 is better than the durability of the stitches with odd stitch 11 + odd stitch 11 or even stitch 12 + even stitch 12. The specific stitching methods for odd-numbered seams 11 and even-numbered seams 12 are the same as those described above, and will not be repeated here.

[0082] S34: In the first stitch L1, part of it is a 10-seam stitch and the rest is a 20-seam stitch; in the second stitch L2, it is a 20-seam stitch.

[0083] Specifically, this can be understood as the first stitch L1 consisting of a portion of alternate stitches 10, while the remaining portion is entirely stitched 20 instead of alternate stitches 10. For example, the first half of the first stitch L1 consists of alternate stitches 10, and the second half consists entirely stitched 20. Alternatively, the first half of the first stitch L1 consists entirely stitched 20, and the second half consists of alternate stitches 10.

[0084] In the first stitch L1, the interlaced stitches 10 can be either odd-numbered stitches 11 or even-numbered stitches 12, and this application does not impose any restrictions on this. For example, a portion of the first stitch L1 may be odd-numbered stitches 11 or even-numbered stitches 12, while the remaining portion may be all stitches 20; the second stitch L2 may be all stitches 20.

[0085] S35: The first stitching L1 is all stitching 20, and a part of the second stitching L2 is gap stitching 10, and the rest is all stitching 20.

[0086] Specifically, similar to step S34, but in this embodiment, the first stitching L1 is all stitching 20, and a part of the second stitching L2 is gap stitching 10, and the rest is all stitching 20. For example, the first half of the second stitching L2 is gap stitching 10, and the second half is all stitching 20. Alternatively, the first half of the second stitching L2 is all stitching 20, and the second half is gap stitching 10.

[0087] Specifically, similar to step S34, but in this embodiment, the first stitching L1 is all stitching 20, and a part of the second stitching L2 is gap stitching 10, and the rest is all stitching 20. For example, the first half of the second stitching L2 is gap stitching 10, and the second half is all stitching 20. Alternatively, the first half of the second stitching L2 is all stitching 20, and the second half is gap stitching 10.

[0088] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 a schematic block diagram of the sub-step of step S1 provided by the application; Figure 5 is a specific step schematic block diagram provided by the application, in which the first stitching L1 is odd stitching.

[0089] In an embodiment, the step S1 of performing the first stitching L1 along the stitching route 101 in the odd-to-even stitching mode can include:

[0090] S11: Obtain the stitching mode of the first stitching L1; wherein the stitching mode includes all stitching 20, odd stitching 11 or even stitching 12.

[0091] Specifically, obtaining the stitching mode of the first stitching L1 can be understood as obtaining which one or more of all stitching 20, odd stitching 11 and even stitching 12 is used for the first stitching L1 through the information included in the request instruction of the first stitching L1.

[0092] In an embodiment, the all stitching 20 stitching mode can be: from the starting position of the stitching object 100, starting from the first needle, the stitching head mechanism 50 adopts a continuous, non-gapped stitching mode.

[0093] S12: According to the stitching mode, determine the movement distance of the stitching head mechanism 50 each time and the stitching parameters of the stitching head mechanism 50.

[0094] Specifically, as described above, the movement distance of the stitching head mechanism 50 each time can be obtained according to the distance between the first needle and the last needle of the stitching object 100, and the pattern width in the stitching parameters.

[0095] S13: sending corresponding control instructions to the driving assembly 40 based on the distance parameter and the stitch parameter of each movement.

[0096] Specifically, the driving assembly 40 of the stitch head mechanism 50 includes a first driving member 41 and a second driving member 42. The first driving member 41 is used to move the stitch head mechanism 50, and the second driving member 42 is used to perform the stitching operation. The first driving member 41 and the second driving member 42 are controlled by the control system 30 and work alternately. When the first driving member 41 drives the stitch head mechanism 50 to move, the second driving member 42 does not work. When the second driving member 42 drives the stitch head mechanism 50 to perform the stitching operation, the first driving member 41 does not work. The control system 30 sends corresponding control instructions to the driving assembly 40 to make the first driving member 41 and the second driving member 42 perform corresponding operations.

[0097] S14: driving the stitch head mechanism 50 to move a corresponding distance along the stitching route 101 by the first driving member 41, and driving the stitch head mechanism 50 to perform a corresponding stitching operation of the first stitching L1 along the stitching route 101 by the second driving member 42.

[0098] Specifically, the first driving member 41 and the second driving member 42 receive the control instructions of the control system 30 to control the stitch head mechanism 50 to move a corresponding distance and perform a corresponding stitching operation along the stitching route 101. For example, odd stitching 11, even stitching 12, or all stitching 20 in a certain pattern.

[0099] In this embodiment, the working mode of the first driving member 41 and the second driving member 42 can be that the first driving member 41 drives the stitch head mechanism 50 to move a preset number of pulses of the pattern, the second driving member 42 drives the stitch head mechanism 50 to stitch once, then the first driving member 41 drives the stitch head mechanism 50 to move a preset number of pulses of the pattern again, the second driving member 42 drives the stitch head mechanism 50 to stitch once again, and so on until all stitching operations of the first stitching L1 of the stitching route 101 are completed.

[0100] In an embodiment, as shown in FIG. 6, the first stitching L1 in the above step S331 is the odd stitching 11, which can include: Figure 5

[0101] S3311a: starting from the first needle, driving the stitch head mechanism 50 to perform stitching in the opposite eyelet method by the second driving member 42.

[0102] Specifically, when the odd stitching 11 is performed, the stitching directly starts from the first needle of the stitching route 101 without needing to idle the first needle. The first driving member 41 and the second driving member 42 drive the stitch head mechanism 50 to perform the first needle stitching operation in the opposite eyelet method. ​

[0103] S3312a: The first driving member 41 drives the sewing head mechanism 50 to move the two needles, and the second driving member 42 is not working during the process.

[0104] Specifically, the first driving member 41 drives the sewing head mechanism 50 to move, and no sewing is needed during the movement of the sewing head mechanism 50, so the second driving member 42 is not working during the process.

[0105] S3313a: After the sewing head mechanism 50 moves the two needles, the second driving member 42 drives the sewing head mechanism 50 to perform sewing in the opposite direction.

[0106] Specifically, after the sewing head mechanism 50 completes the movement operation, it then performs the sewing operation, and at this time the second driving member 42 drives the sewing head mechanism 50 to perform the sewing operation in the opposite direction. It can be understood that when the sewing operation is performed, the second driving member 42 is working, and the first driving member 41 is not working.

[0107] S3314a: The above steps are repeatedly executed until the first sewing L1 of the sewing route 101 is completed.

[0108] Specifically, the above steps S3312a and S3313a are repeatedly executed until the first sewing L1 of the sewing route 101 is completed.

[0109] For example, the request instruction of the first sewing L1 contains: on the sewing route 101 of a sewing object 100, the sewing is performed in a certain pattern with all stitches 20, then the control system 30 can calculate the total number of stitches on the sewing route 101 of the sewing object 100 according to the width of each needle of the pattern, and the distance of each forward movement of the sewing head mechanism 50 according to the distance, and when the number of movements of the sewing head mechanism 50 reaches the total number of stitches, the first sewing L1 is completed.

[0110] Please refer to Figure 6 , Figure 6 is Figure 1 a schematic block diagram of the sub-steps of step S2 provided by the present application; Figure 7 is a specific step schematic block diagram of the second sewing L2 provided by the present application.

[0111] In an embodiment, the step S2 of performing the second sewing L2 along the sewing route 101 in the opposite direction can include:

[0112] S21: Obtain the sewing method of the second sewing L2; wherein the sewing method includes all stitches 20, odd number of stitches 11 or even number of stitches 12.

[0113] Specifically, the way of acquiring the second stitching L2 can be understood as acquiring which one or more of the full stitching 20, the odd stitching 11 and the even stitching 12 is used to perform the second stitching L2 by the information included in the request instruction of the second stitching L2.

[0114] S22: determining the moving distance of the sewing head mechanism 50 for each stitching and the stitching parameters of the sewing head mechanism 50 according to the stitching way.

[0115] Specifically, the moving distance of the sewing head mechanism 50 for each stitching is determined according to the distance between the first needle and the last needle of the sewing object 100 and the pattern width in the stitching parameters, which is the same as in step S12.

[0116] S23: sending corresponding control instructions to the driving assembly 40 based on the distance parameters of each movement and the stitching parameters.

[0117] Specifically, the driving assembly 40 of the sewing head mechanism 50 includes a first driving member 41 and a second driving member 42, the first driving member 41 is used to move the sewing head mechanism 50, and the second driving member 42 is used to perform the stitching operation. The control system 30 sends corresponding control instructions to the driving assembly 40 to make the first driving member 41 and the second driving member 42 perform corresponding operations.

[0118] S24: driving the sewing head mechanism 50 to move a corresponding distance along the sewing route 101 by the first driving member 41, and driving the sewing head mechanism 50 to perform a corresponding stitching operation of the second stitching L2 along the sewing route 101 by the second driving member 42.

[0119] Specifically, the first driving member 41 and the second driving member 42 receive the control instructions of the control system 30 to control the sewing head mechanism 50 to move a corresponding distance and to perform a corresponding stitching operation along the sewing route 101. For example, odd stitching 11, even stitching 12 or full stitching 20 in a certain pattern.

[0120] In an embodiment, as shown in Figure 7 the second stitching L2 in the above step S331 is even stitching 12, which can include:

[0121] S3311b: the first needle is empty, and the sewing head mechanism 50 is driven by the second driving member 42 to perform stitching in the even stitching mode from the second needle.

[0122] Specifically, unlike the odd stitching 11, the even stitching 12 starts stitching from the second needle, so the first needle position of the even stitching 12 needs to be empty, and the sewing head mechanism 50 is driven by the second driving member 42 to stitch at the second needle position once.

[0123] S3312b: drive the two needles to move by the first driving member 41, and the second driving member 42 does not work in the process.

[0124] Specifically, after the first needle thread is completed, the two needles are driven to move by the first driving member 41, and no need to thread in the process of moving the needle mechanism 50, so the second driving member 42 does not work in the process.

[0125] S3313b: after the needle mechanism 50 moves the two needles, the needle mechanism 50 is driven by the second driving member 42 to thread in the opposite eyelet way.

[0126] Specifically, after the needle mechanism 50 completes the movement, the needle mechanism 50 is driven by the second driving member 42 to thread at this time, it can be understood that the second driving member 42 works and the first driving member 41 does not work when threading.

[0127] S3314b: the above steps are executed in a loop until the second thread L2 of the sewing route 101 is completed.

[0128] Specifically, the above steps S3312b and S3313b are executed in a loop until the second thread L2 of the sewing route 101 is completed.

[0129] The needle control method disclosed in the application comprises: threading in the opposite eyelet way along the sewing route for the first time; and threading in the opposite eyelet way along the sewing route for the second time; wherein at least part of the route in the first thread and the second thread of the same sewing route is threaded in the needle separation way. The application threads the same sewing route in the opposite eyelet way for multiple times to achieve the firm and durable effect of blind stitching, and does not affect the comfort at the same time. In addition, the multiple threads of the same sewing route can be threaded in the needle separation way, so as to facilitate partial threading and various style threading, and improve the diversity and flexibility of threading. The application develops a multi-combination stitching technology on the opposite eyelet way of the knitting machine mechanism, realizes the combination of the advantages of opposite eyelet way and blind stitching, and greatly improves the diversification and applicability of the needle of the knitting machine.
