[0007] Problems to be solved by the invention

[0008] Due to the diversification of consumer demands, producers hope to effectively weave small batches and multiple varieties of knitted fabrics. In order to cope with this demand, no matter what kind of knitted fabric, a knitting method for knitting the knitted fabric that can be woven efficiently is required.

[0009] One of the objects of the present invention is to provide a knitting method for a knitted fabric having excellent knitting efficiency. One of the objects of the present invention is to provide a knitting design system for creating a knitting program having excellent knitting efficiency. One of the objects of the present invention is to provide a storage medium storing a knitting program having excellent knitting efficiency.

[0010] Means to solve the problem

[0011] The inventors investigated all the processes for weaving a knitted fabric and their arrangement order. As a result, no matter what kind of knitted fabric, in the process of knitting the knitted fabric, there are many parts arranged in the order of lateral shift process, loop transfer process, lateral shift process, and loop transfer process. In the past, the lateral shift process and the loop transfer process were performed in one knitting coil horizontal row. In other words, the above four processes are performed in two knitting coil horizontal rows that make the slide reciprocate. The inventors found that by performing these actions while the slide moves in one direction, the overall knitting efficiency of the knitted fabric is significantly improved. The following lists the knitting method, knitting design system and storage medium of the knitted fabric of the present invention.

[0012] <1> The knitting method of a knitted fabric of the present invention is characterized in that the knitting fabric is knitted by performing multiple knitting coil rows using a flat knitting machine having a first needle bed and a second needle bed that can be relatively moved laterally and a slide equipped with at least two cam systems, and the multiple knitting coil rows include at least one specific knitting coil row, and in each specific knitting coil row, a first horizontal shifting process, a first transfer process, a second horizontal shifting process, and a second transfer process are sequentially performed during the process in which the slide moves in one direction and passes through a knitting area, and the one knitting area is an area in which a series of coils continuous in the knitting width direction are fixed.

[0013] Here, a series of loops in a knitting area may be formed by a single knitting yarn or may be a loop formed by joining a plurality of loops formed by different knitting yarns. In addition, there is a case where the carriage passes through a plurality of knitting areas when moving in a specific knitting row. For example, in the knitting of a pullover, there is a case where the right sleeve, the front and back body pieces, and the left sleeve are stuck in positions separated in the length direction of the needle bed. In this case, since the knitting area of ​​the right sleeve, the knitting area of ​​the front and back body pieces, and the knitting area of ​​the left sleeve are separated in the knitting width direction, they are considered to be different things.

[0014] <2> As one aspect of the knitting method of the knitted fabric of the present invention, there may be mentioned an aspect in which the flat knitting machine includes a self-propelled wire feeder, and a knitting step is further performed after the first raking step in the specific knitting course.

[0015] <3> The knitting design system of the present invention comprises an input unit for a user to edit design data related to knitting of a knitted fabric and a creation unit for creating a knitting program readable by a computer equipped on a flat knitting machine based on the design data, wherein the creation unit is configured to enable the flat knitting machine to execute the knitting program. <1> or <2> The computer controls the knitting program of the flat knitting machine according to the knitting method of the knitted fabric.

[0016] <4> The storage medium of the present invention stores a knitting program readable by a computer equipped on a flat knitting machine, wherein the knitting program causes the flat knitting machine to execute the above <1> or <2> The computer controls the flat knitting machine in a manner that allows the knitting method of the knitted fabric to be controlled.

[0017] [Effects of the Invention]

[0018] In the knitting method of the knitted fabric of the present invention, since two traverses and two transfers are performed in one specific knitting course, the total number of knitting courses for completing the knitted fabric is reduced. In addition, by performing the specific knitting course, there is a possibility that the number of empty courses is greatly reduced. Therefore, according to the knitting method of the knitted fabric of the present invention, the knitting efficiency of the knitted fabric can be significantly improved.

[0019] When the flat knitting machine is equipped with a self-propelled wire feeder, there is a case where a knitting process can be further included in a specific knitting course. By performing a knitting process in one knitting course, the knitting efficiency of the knitted fabric can be further improved.

[0020] The knitting design system of the present invention can automatically create a knitting program that can knit a knitted fabric efficiently based on knitting data input by a user. As shown in the embodiment described below, the user only needs to input the knitting data on the knitting design system.

[0021] By using the knitting program stored in the storage medium of the present invention, a flat knitting machine can efficiently knit knitted fabrics. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Modes for carrying out the invention

[0028] Hereinafter, a knitting method for a knitted fabric, a knitting design system, and a storage medium according to an embodiment will be described with reference to the drawings.

[0029] <Implementation Method 1>

[0030] 《Knitting Example 1》

[0031] In this embodiment, first, an example of a knitting method of a knitted fabric of the present invention using a four-needle bed flat knitting machine is described based on the drawings. As described later, the knitting method of the knitted fabric of the present invention may also be performed by a two-needle bed flat knitting machine.

[0032] The 4-needle-bed flat knitting machine has a lower front needle bed, a lower rear needle bed, an upper front needle bed, and an upper rear needle bed. Hereinafter, the lower front needle bed, the lower rear needle bed, the upper front needle bed, and the upper rear needle bed are represented as FD, BD, FU, and BU, respectively. In this example, FD and FU are the first needle bed, and BD and BU are the second needle bed. FD and BD are facing each other. FU arranged on the top of FD and BU arranged on the top of BD are facing each other. The 4-needle-bed flat knitting machine also has a plurality of wire feeders and slides. Use Figure 1 A schematic diagram is used to simply illustrate the relationship between the needle bed, the wire feeder and the slide.

[0033] Figure 1 This is a schematic diagram of a part of the flat knitting machine 5 viewed from the FD side. Figure 1 FU is omitted in the illustration. The carriage 6 equipped on the flat knitting machine 5 reciprocates on the needle bed. The carriage 6 in this example has three cam systems 6A, 6B, and 6C. Each cam system is a general term for multiple cams arranged at positions corresponding to FD, FU, BD, and BU in the carriage 6. Each cam system can also perform any one of the knitting process and the loop transfer process. For example, a cam system that performs a knitting process in a certain knitting coil row can also perform a loop transfer process in other knitting coil rows. The number of cam systems can be either two cam systems 6A and 6B or four cam systems 6A to 6C plus one cam system. Each wire feeder 8 is installed to be able to move on a track 7 arranged above the needle bed.

[0034] exist Figure 2 In the example of forming two overlapping stitches at positions separated from each other within a narrow range of 10 stitches or less, a part of the knitting process for forming the shoulder line of the pullover sweater is shown. Specifically, after the first traverse is performed, the first overlapping stitch is formed by the first transfer. Then, after the second traverse is performed in the same direction as the first traverse, the second overlapping stitch is formed by the second transfer.

[0035] Figure 2The "S+number" shown in the column on the left end of the paper is the number of the knitting process. In the second column A from the left, the formation state of the coil in each knitting process is shown. The black dot in column A represents the knitting needle, the Ω mark represents the coil, the inverted triangle mark represents the wire feeder 8, and the straight arrow represents the transfer loop. In the third column B from the left, the horizontal rows of knitting coils used to perform the knitting process in column A in the knitting method of the previous knitted fabric are shown. In the column C on the right end, the horizontal rows of knitting coils used to perform the knitting process in column A in the knitting method of the knitted fabric of this example are shown. First, refer to column A for the description of each knitting process.

[0036] In S1, the wire feeder 8 is moved to the left direction, and after a plurality of stitches are knitted in BD, five stitches on the left side of the stitches are transferred to FU.

[0037] In S2, after BD and BU are shifted to the left by one pitch, the three right stitches of the stitches locked on FU are shifted to BD. By this shifting, overlapping stitches are formed on BD.

[0038] In S3, after BD and BU are shifted to the left by one pitch, the two stitches locked on FU are shifted to BD. By this shifting, overlapping stitches are further formed on BD.

[0039] In S4, after BD and BU are transversely shifted by one pitch in the right direction, the stitch at the left end of FD is shifted toward BD. By this stitch transfer, a double stitch is further formed on BD.

[0040] In S5, after BD and BU are transversely shifted by two pitches in the right direction, the stitch at the right end of FD is shifted toward BD. By this stitch transfer, a further overlapping stitch is formed on BD.

[0041] Next, the structure of the knitting course in the knitting method of the conventional knitted fabric shown in the column B will be described. Figure 1 The moving direction of the carriage 6 is shown in FIG. 1 . The upward arrow indicates the transfer of the needle from the front needle bed to the rear needle bed, and the downward arrow indicates the transfer of the needle from the rear needle bed to the front needle bed. The double-dot dash line indicates Figure 1 The cam system on the moving direction side of the carriage 6 is the preceding cam system. The "K" recorded in the corresponding part of each cam system indicates the knitting process, "TR" indicates the transfer process, and "R" indicates the lateral movement process. The blank arrow on the upper part of "R" indicates the lateral movement direction.

[0042] As shown in the column B, in the conventional knitting method of a knitted fabric, corresponding five knitting courses are performed on a one-to-one basis in each step.

[0043] Next, the structure of the knitting coil row in the knitting method of the knitted fabric of the embodiment shown in column C is described. The view in column C is the same as that in column B. As shown in column C, in the knitting method of the knitted fabric of the embodiment, the knitting process of column A is performed by three knitting coil rows. Specifically, S1 is performed in the first knitting coil row in column C. S2 and S3 are performed in the second knitting coil row. S4 and S5 are performed in the third knitting coil row. The second knitting coil row and the third knitting coil row refer to the knitting coil rows that are performed when the carriage 6 (refer to Figure 1 ) is a specific knitting coil row in which two lateral shifts and two transfers are performed during the process of moving the carriage 6 in one direction. More specifically, in the second knitting coil row, the first lateral shift process, the first transfer process, the second lateral shift process, and the second transfer process are performed in sequence during the process of moving the carriage 6 in the right direction. In the first lateral shift process, BD and BU are lateral shifted to the left direction. In the first transfer process, the coils are transferred by the first cam system 6A in the traveling direction of the carriage 6. In the second lateral shift process, BD and BU are lateral shifted to the left direction. In the second transfer process, the coils are transferred by the third cam system 6C. Here, the second lateral shift process is performed when the cam systems 6A, 6B, and 6C are not acting on the knitting needles. The second lateral shift process in the subsequent description is also performed when the cam systems 6A, 6B, and 6C are not acting on the knitting needles.

[0044] In the third knitting row, while the carriage 6 is moved to the left, the first traverse step, the first transfer step, the second traverse step, and the second transfer step are sequentially performed. In the first traverse step, the BD and the BU are traversely moved to the right. In the first transfer step, the first cam system 6C in the traveling direction of the carriage 6 transfers the stitches. In the second traverse step, the BD and the BU are traversely moved to the right. In the second transfer step, the stitches are transferred by the third cam system 6A.

[0045] As described above, in the knitting method of the knitted fabric of the present invention shown in column C, the number of knitting courses for performing the knitting process of column A is smaller than that of the knitting method of the conventional knitted fabric shown in column B. Therefore, the knitting method of the knitted fabric of embodiment 1 can knit the knitted fabric more efficiently than the knitting method of the conventional knitted fabric.

[0046] 《Knitting Example 2》

[0047] In knitting example 2, based on Figure 3 , 4A part of the knitting process of hidden stitch processing is explained. Hidden stitch processing is a process of repeatedly forming overlapping stitches by transferring stitches and knitting new stitches on the overlapping stitches within a narrow range of 3 stitches. Hidden stitch processing is a process that can be performed at a high frequency in any knitted fabric. Figure 3 , 4 The hidden stitch processing of the present invention is, for example, a hidden stitch processing for preventing the terminal end of a knitted fabric such as a collar from being scattered. In this hidden stitch processing, the direction of the first traverse is different from the direction of the second traverse. Figure 3 , 4 The view and Figure 2 In knitting example 2, Figure 1 The wire feeder 8 is a self-propelled flat knitting machine 5. The self-propelled wire feeder 8 is a wire feeder 8 that can move independently of the carriage 6. Figure 3 , 4 In FIG. 8 , the moving direction of the wire feeder 8 is indicated by a fully painted arrow.

[0048] exist Figure 3 In S1 shown in the A column of , the wire feeder 8 is moved to the right direction to weave the coil at the left end of BD. In S2, the coil at the left end of BD is moved to FU. In S3, after BD and BU are moved horizontally by one pitch in the left direction, the coil of FU is overlapped on the coil at the left end of BD. In S4, the wire feeder 8 is moved to the left direction. In S5, after BD and BU are moved horizontally by one pitch in the right direction, the wire feeder 8 is moved to the right direction to weave continuous coils in the longitudinal direction of the overlapping coils. The first hidden coil processing is completed by S1 to S5.

[0049] In S6, the stitch knitted in S5 is transferred from BD to FU. Figure 4 In S7, after BD and BU are shifted to the left by one pitch, the coil of FU is overlapped on the coil at the left end of BD. In S8, the wire feeder 8 is moved to the left. In S9, after BD and BU are shifted to the right by one pitch, the wire feeder 8 is moved to the right to weave the coils continuous in the longitudinal direction of the overlapping coils of BD. The second hidden coil processing is completed by S6 to S9. After S9, the same weaving as S2 to S5 is performed. In S10, the initial process of the third hidden coil processing is shown.

[0050] In the conventional knitting method of a knitted fabric shown in the column B, five knitting courses are performed to perform the knitting steps in the column A. Specifically, in the conventional knitting method of a knitted fabric, two steps are performed in each knitting course.

[0051] Next, in the knitting method of the present invention shown in column C, the knitting process of column A is performed by three knitting courses. Figure 3 In the first knitting row of column C, S1 and S2 are executed. In the second knitting row, S3 to S6 are executed. Figure 4 In the third knitting row of column C, S7 to S10 are performed. Figure 3 The second knitting course of column C and Figure 4 The third knitting row of the C column is a specific knitting row of the knitting loops that performs two lateral shifting steps, two transfer steps, and one knitting step while the carriage is moving in one direction. More specifically, Figure 3 In the second knitting coil row of column C of , in the process of moving the carriage 6 to the left, the first lateral shifting process, the first transfer process, the second lateral shifting process, the knitting process, and the second transfer process are sequentially performed. In the case of this knitting example, the order of the second lateral shifting process and the knitting process can be reversed. In the first lateral shifting process, BD and BU are lateral shifted to the left. In the first transfer process, the coils are transferred by the first cam system 6C. In the second lateral shifting process, BD and BU are lateral shifted to the right. In the knitting process, the coils are knitted by the second cam system 6B. In the second knitting coil row of this example, the wire feeder 8 is preliminarily moved in the same direction as the traveling direction of the carriage 6 before the knitting process. The movement of this wire feeder 8 is a movement equivalent to S4, and is a preparatory process for moving the wire feeder 8 to the right in S5 to perform the knitting process. The knitting process is performed by moving the wire feeder 8 in the direction opposite to the traveling direction of the carriage 6. In the second transfer process, the coils are transferred by the third cam system 6A.

[0052] exist Figure 4 In the third horizontal row of knitting coils shown in the C column, in the process of moving the carriage 6 to the right direction, the first horizontal shift process, the first transfer process, the second horizontal shift process, the knitting process and the second transfer process are performed in sequence. In the case of this knitting example, the order of the second horizontal shift process and the knitting process can be reversed. In the first horizontal shift process, BD and BU are horizontally shifted to the left direction. In the first transfer process, the coils are transferred by the first cam system 6A. In the second horizontal shift process, BD and BU are horizontally shifted to the right direction. In the knitting process, the coils are knitted by the second cam system 6B. In the third horizontal row of knitting coils of this example, the wire feeder 8 is moved in the direction opposite to the travel direction of the carriage 6 before the knitting process. The knitting process is performed by moving the wire feeder 8 in the same direction as the travel direction of the carriage 6. In the transfer process, the coils are transferred by the third cam system 6C.

[0053] As explained above, Figure 3 , 4The knitting method of the knitted fabric of the present invention shown in the column C can knit the knitted fabric more efficiently than the knitting method of the conventional knitted fabric shown in the column B.

[0054] 《Weaving program and storage medium》

[0055] The knitting program for performing the knitting method of the knitted fabric in the flat knitting machine is a knitting program for causing a computer equipped on the flat knitting machine 5 to control the flat knitting machine 5 so that the flat knitting machine 5 (see Figure 1 ) executes a plurality of knitting rows including a specific knitting row.

[0056] In the flat knitting machine 5, the cam provided on the carriage 6 running on the needle bed acts on the butt provided on the knitting needle, and the knitting needle moves forward and backward along the needle groove of the needle bed to form a loop. The flat knitting machine 5 is equipped with a needle selection mechanism that determines which knitting needle performs what action, a carriage control mechanism that controls the running of the carriage 6 and the appearance and disappearance of the cam, and a transverse movement control mechanism that controls the transverse movement of the needle bed. The knitting program controls the movement of the carriage 6, the transverse movement position of the needle bed, and the action of each knitting needle by issuing instructions to these mechanisms, so that the flat knitting machine can knit the knitted fabric.

[0057] The storage medium storing the knitting program can be mounted on the knitting design system or on the flat knitting machine. The storage medium can also be a removable storage medium for transferring the knitting program created by the knitting design system to the flat knitting machine. Examples of removable storage media include CD-ROMs, USB memories, and magnetic disks. Here, the knitted fabric design system refers to a system that allows a user to design a knitted fabric on a screen and creates a knitting program for operating the flat knitting machine based on the user's design.

[0058] Knitting Design System

[0059] like Figure 5 As shown in the functional block diagram of the present invention, a knitting design system 1 for knitted fabrics that creates the knitting program based on the user's design includes an input unit 2, a creation unit 3, a memory 4, and a display unit 10. The knitting design system 1 for knitted fabrics is configured to automatically create the knitting program based on design data. The following briefly describes each structure of the knitting design system 1, and then describes the steps of creating the knitting program based on the user's input information.

[0060] The input unit 2 is used by the user when editing the design data, and is composed of a keyboard, a mouse, a scanner, a digitizer, etc. The design data includes information on what shape and size of the knitted fabric to be knitted, information on the type of knitting yarn, information on the knitting units constituting the knitted fabric, information on the knitting code assigned to each knitting unit, etc. The knitting code information includes the position of the knitting unit and the knitting code assigned to the position.

[0061] Here, the knitting unit of the knitted fabric is a unit corresponding to one amount of the coil in the knitted fabric. In addition, the knitting code assigned to each knitting unit, for example, represents the knitting action performed by the flat knitting machine by color, number, figure or a combination thereof. For example, the knitting code represented by red is specified as a knitting code for causing the flat knitting machine to knit the front coil. Of course, multiple knitting actions can also be specified by one knitting code. For example, a knitting code for transferring the coil after knitting the coil can be cited. These knitting codes are stored in the memory 4 described later.

[0062] The creation unit 3 is a part for creating a knitting program for a knitted fabric and can be formed by, for example, a computer. The creation unit 3 includes a determination unit 31 for determining whether a specific knitting course can be executed based on design data and a construction unit 32 for creating a knitting program based on the determination result of the determination unit 31.

[0063] The determination unit 31 includes a first determination unit 31A and a second determination unit 31B. The first determination unit 31A refers to all the steps for knitting the knitted fabric and extracts a process group constituting a specific knitting course from all the steps. The following three process groups can be cited as examples.

[0064] (1) A process group arranged in the order of lateral shift process, circle transfer process, lateral shift process, and circle transfer process.

[0065] (2) A process group arranged in the order of lateral shifting process, loop transfer process, lateral shifting process, weaving process, and loop transfer process.

[0066] (3) A process group arranged in the order of lateral shifting process, loop transfer process, weaving process, lateral shifting process, and loop transfer process.

[0067] The second determination unit 31B determines whether each process group extracted by the first determination unit 31A can be executed while the carriage 6 is moved in one direction. Whether all the processes included in one process group can be executed is determined based on the following information, for example. The second determination unit 31B determines whether the traverse process can be executed when the cam systems 6A, 6B, and 6C are not acting on the knitting needles based on the following information

[0068] (1) Types of cam systems 6A, 6B, 6C provided in the flat knitting machine 5. Examples of the types of cam systems include a cam system dedicated to the knitting process, a cam system dedicated to the stitch transfer process, and a cam system capable of performing both the knitting process and the stitch transfer process.

[0069] (2) The number of triangle systems 6A, 6B, 6C.

[0070] (3) The moving speed of the carriage 6.

[0071] (4) The distance between the cam system performing the first loop transfer process and the cam system performing the second loop transfer process, and the distance between the cam system performing the loop transfer process and the cam system performing the knitting process.

[0072] (5) The positions on the needle bed where the first and second stitch transfer processes are performed.

[0073] The construction unit 32 creates a knitting program that sets the weaving, the movement of the knitting needles, the release step of the knitting yarn, etc. based on the design data. In this example, the construction unit 32 creates a knitting program including a specific knitting course based on the determination result of the determination unit 31. When the above-mentioned process group is not extracted by the first determination unit 31A, the construction unit 32 creates a knitting program composed of the previous knitting courses. When the above-mentioned process group is extracted by the first determination unit 31A, the construction unit 32 creates a knitting program in a manner that executes the specific knitting course for the process group for which the determination result by the second determination unit 31B is "YES". The construction unit 32 creates a knitting program in a manner that executes the previous knitting course for the process group for which the determination result by the second determination unit 31B is "NO". The knitting program created by the construction unit 32 is sent to the flat knitting machine 5 via a recording medium such as a disk, wired, wireless, etc.

[0074] The memory 4 is a storage medium such as a solid state drive, a hard disk, etc. In the memory 4, information such as design data and knitting codes are stored.

[0075] The display unit 10 is used to visually grasp information related to the design of the knitted fabric without particular limitation. As the display unit 10, for example, a liquid crystal display etc. can be cited. If a touch panel is used as the display unit 10, the display unit 10 can be made to bear a part of the function of the input unit 2.

[0076] The knitting design system 1 having the above-described configuration can automatically create a knitting program for executing a plurality of knitting courses including at least one specific knitting course. According to this knitting program, a knitted fabric can be knitted more efficiently than before.

[0077] <Other Embodiments>

[0078] The knitting method of the knitted fabric of the present invention can also be performed by a flat knitting machine equipped with two or four cam systems. In particular, if it is a flat knitting machine equipped with four cam systems, there is a possibility that the knitted fabric can be knitted more efficiently than a flat knitting machine equipped with three cam systems. In a flat knitting machine equipped with four cam systems, since it is easy to ensure the distance between the cam system that performs the first stitch transfer process and the cam system that performs the second stitch transfer process, there is a possibility that the number of specific knitting coil rows can be increased. In addition, in this flat knitting machine, there is also a possibility that the number of empty coil rows where only the carriage is moved can be significantly reduced.

[0079] The knitting method of the knitted fabric of the present invention can also be performed by a two-needle bed flat knitting machine. When a two-needle bed flat knitting machine is used, the front knitted fabric portion and the rear knitted fabric portion are knitted by draw-needle knitting. The so-called draw-needle knitting refers to knitting in a state where an empty needle is arranged between adjacent loops. The empty needle arranged between adjacent loops can be used for loop transfer.
