[0004] [Patent Document 1] International Publication No. 2002 / 033598 Summary of the Invention [Problem to be solved by the invention]

[0005] Due to the diversification of consumer needs, there is a need from producers to efficiently knit small lots and a wide variety of knitted fabrics. To meet this need, there is a demand for a knitting method that can efficiently knit any type of knitted fabric.

[0006] An object of the present invention is to provide a method for knitting a knitted fabric having excellent knitting efficiency.An object of the present invention is to provide a knit design system for creating a knitting program having excellent knitting efficiency.An object of the present invention is to provide a storage medium storing a knitting program having excellent knitting efficiency. [Means for solving the problem]

[0007] The inventors have investigated all the steps for knitting one knitted fabric and their order of arrangement. As a result, it has become clear that in any knitted fabric, there are many points in the knitting process in which the racking step, the transfer step, the racking step, and the transfer step are arranged in this order. Conventionally, the racking step and the transfer step are performed in one knitting course. In other words, the above four steps are performed in two knitting courses in which the carriage is moved back and forth. The inventors have found that the knitting efficiency of the entire knitted fabric is dramatically improved by performing these operations while the carriage moves in one direction. The knitting method, knit design system, and storage medium of the present invention are listed below.

[0008] <1> The knitting method of the knitted fabric of the present invention includes the steps of: A method for knitting a knitted fabric by executing a plurality of knitting courses using a flat knitting machine including a first needle bed and a second needle bed that can be relatively racked and a carriage equipped with at least two cam systems, comprising: The plurality of knitting courses includes at least one specific knitting course, In each specific knitting course, while the carriage moves in one direction and passes through one knitting area, a first racking step, a first stitch transfer step, a second racking step, and a second stitch transfer step are performed in this order; The one knitting region is a region in which a series of stitches continuing in the knitting width direction are held.

[0009] Here, the series of stitches in the knitting area may be made of one knitting yarn, or may be a combination of multiple stitch rows made of different knitting yarns. In addition, the carriage may pass through multiple knitting areas when moving in a specific knitting course. For example, in knitting a sweater, the right sleeve, the body, and the left sleeve may be held at positions separated in the length direction of the needle bed. In this case, the knitting area of ​​the right sleeve, the knitting area of ​​the body, and the knitting area of ​​the left sleeve are considered to be separate entities because they are separated in the knitting width direction.

[0010] <2> As one embodiment of the knitting method of the knitted fabric of the present invention, The flat knitting machine is equipped with a self-propelled yarn feeder, In the specific knitting course, a knitting step may be performed after the first racking step.

[0011] <3> The knit design system of the present invention comprises: An input unit for a user to edit design data relating to knitting of a knitted fabric; A knit design system including a creation unit that creates a knitting program readable by a computer provided in a flat knitting machine based on the design data, The creation unit <1> or <2> A knitting program is created that causes the computer to control the flat knitting machine to execute the knitting method of the knitted fabric.

[0012] <4> The storage medium of the present invention comprises: A storage medium storing a knitting program readable by a computer provided in a flat knitting machine, The knitting program is <1> or <2> The computer controls the flat knitting machine to execute the knitting method of the knitted fabric. Effect of the Invention

[0013] In the knitting method of the knitted fabric of the present invention, two rackings and two transfers are performed in one specific knitting course, so the total number of knitting courses required to complete the knitted fabric is reduced. In addition, by performing a specific knitting course, the number of empty courses can be significantly reduced. Therefore, according to the knitting method of the knitted fabric of the present invention, the knitting efficiency of the knitted fabric can be dramatically improved.

[0014] When the flat knitting machine is equipped with a self-propelled yarn feeder, a specific knitting course may further include a knitting step. By performing an additional knitting step in one knitting course, the knitting efficiency of the knitted fabric can be further improved.

[0015] The knit design system of the present invention can automatically create a knitting program that can efficiently knit a knitted fabric based on knitting data input by the user. The user only needs to input the knitting data on the knit design system, as shown in the embodiment described below.

[0016] By using the knitting program stored in the storage medium of the present invention, it is possible to cause the flatbed knitting machine to knit a fabric efficiently. [Brief description of the drawings]

[0017] [Figure 1] FIG. 1 is a partial schematic diagram of a flat knitting machine equipped with a carriage on which three cam systems are mounted. [Diagram 2] FIG. 2 is an explanatory diagram of a knitting example 1 shown in the embodiment. [Diagram 3] FIG. 3 is an explanatory diagram of a knitting example 2 shown in the embodiment. [Figure 4] FIG. 4 is an explanatory diagram following FIG. [Diagram 5] FIG. 5 is a functional block diagram of the knit design system shown in the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, a knitting method for a knitted fabric, a knit design system, and a storage medium according to an embodiment will be described with reference to the drawings.

[0019] <Embodiment 1> <Composition example 1> In this embodiment, first, an example of a method for knitting a knitted fabric of the present invention using a four-bed flat knitting machine will be described with reference to the drawings. As will be described later, it is also possible to execute the knitting method of the knitted fabric of the present invention using a two-bed flat knitting machine.

[0020] The four-bed flat knitting machine includes 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 respectively denoted as FD, BD, FU, and BU. In this example, the FD and FU are the first needle beds, and the BD and BU are the second needle beds. The FD and BD face each other. The FU arranged above the FD and the BU arranged above the BD face each other. The four-bed flat knitting machine further includes multiple yarn feeders and carriages. The relationship between the needle beds, the yarn feeders, and the carriages will be briefly explained using the schematic diagram of FIG. 1.

[0021] FIG. 1 is a schematic diagram of a part of a flat knitting machine 5 seen from the FD side. In FIG. 1, FU is omitted. A carriage 6 provided in the flat knitting machine 5 moves back and forth on the needle bed. In this example, the carriage 6 is provided with three cam systems 6A, 6B, and 6C. Each cam system is a collective name for a plurality of cams provided at positions corresponding to FD, FU, BD, and BU on the carriage 6. Each cam system can perform both the knitting process and the transfer process. For example, a cam system that has performed a knitting process in a certain knitting course can also perform a transfer process in another knitting course. The number of cam systems may be two, cam systems 6A and 6B, or may be four, which is the cam systems 6A to 6C plus another cam system. Each yarn feeder 8 is attached to a rail 7 arranged above the needle bed so as to be able to run.

[0022] FIG. 2 illustrates an example in which two overlapping stitches are formed at positions separated from each other within a narrow range of 10 stitches or less. Here, a part of the knitting process for forming a shoulder line that joins the front and back knitted fabrics in a set-in sweater is shown. Specifically, after the first racking, the first overlapping stitch is formed by the first stitch transfer. Next, after the second racking is performed in the same direction as the first racking, the second overlapping stitch is formed by the second stitch transfer. The "S+number" shown in the column at the left end of the page in FIG. 2 is the number of the knitting process. Column A, the second from the left, shows the state of knitting stitches in each knitting process. In column A, the black dots indicate knitting needles, the Ω marks indicate stitches, the inverted triangle marks indicate yarn feeders 8, and the straight arrows indicate stitch transfer. Column B, the third from the left, shows the knitting course for executing the knitting process in column A in the knitting method of a conventional knitted fabric. Column C, the right end, shows the knitting course for executing the knitting process in column A in the knitting method of the knitted fabric of this example. First, each knitting process will be explained with reference to column A.

[0023] In S1, the yarn feeder 8 is moved leftward, and after a plurality of stitches are knitted in BD, the left five stitches among those stitches are transferred to FU.

[0024] In S2, BD and BU are racked one pitch to the left, and then the three stitches on the right side of the stitches held by FU are transferred to BD. This transfer forms double stitches in BD.

[0025] In S3, BD and BU are racked one pitch to the left, and then the two stitches held by FU are transferred to BD. By this transfer, a double stitch is further formed in BD.

[0026] In S4, BD and BU are racked one pitch to the right, and then the left end stitch of FD is moved to BD. By this transfer, a double stitch is further formed in BD.

[0027] In S5, BD and BU are racked rightward by two pitches, and then the stitch at the right end of FD is transferred to BD. By this transfer, a double stitch is further formed in BD.

[0028] Next, the configuration of the knitting course in the conventional knitting method of the knitted fabric shown in column B will be explained. The left and right arrows indicate the movement direction of the carriage 6 in Fig. 1, the upward arrow indicates the transfer from the front needle bed to the rear needle bed, and the downward arrow indicates the transfer from the rear needle bed to the front needle bed. The two-dot chain line indicates the boundary between the cam systems 6A, 6B, and 6C in Fig. 1. The cam system on the side in the movement direction of the carriage 6 is the leading cam system. The letters "K" written in the places corresponding to each cam system indicate the knit process, "TR" indicates the transfer process, and "R" indicates the racking process. The outline arrow above "R" indicates the racking direction.

[0029] As shown in column B, in the conventional knitting method for knitted fabric, five knitting courses are carried out, each of which corresponds one-to-one to each process.

[0030] Next, the configuration of the knitting course in the knitting method of the knitted fabric according to the embodiment shown in column C will be described. The way of viewing column C is the same as column B. As shown in column C, in the knitting method of the knitted fabric according to the embodiment, the knitting process in column A is performed by three knitting courses. Specifically, in the first knitting course in column C, S1 is performed. In the second knitting course, S2 and S3 are performed. In the third knitting course, S4 and S5 are performed. The second knitting course and the third knitting course are specific knitting courses in which two rackings and two transfers are performed while the carriage 6 (see FIG. 1) is moved in one direction. More specifically, in the second knitting course, the first racking process, the first transfer process, the second racking process, and the second transfer process are performed in this order while the carriage 6 is moved to the right. In the first racking process, BD and BU are racked to the left. In the first transfer process, the stitches are transferred by the first cam system 6A in the moving direction of the carriage 6. In the second racking process, BD and BU are racked to the left. In the second transfer step, the stitch is transferred by the third cam system 6C. Here, the second racking step is performed when the cam systems 6A, 6B, and 6C are not acting on the knitting needles. The second racking step described below is also performed when the cam systems 6A, 6B, and 6C are not acting on the knitting needles.

[0031] In the third knitting course, while the carriage 6 is moved leftward, a first racking process, a first stitch transfer process, a second racking process, and a second stitch transfer process are executed in this order. In the first racking process, BD and BU are racked to the right. In the first stitch transfer process, stitches are transferred by the first cam system 6C in the moving direction of the carriage 6. In the second racking process, BD and BU are racked to the right. In the second stitch transfer process, stitches are transferred by the third cam system 6A.

[0032] As described above, the knitting method of the knitted fabric of the present invention shown in column C has a smaller number of knitting courses for executing the knitting process of column A than the knitting method of the conventional knitted fabric shown in column B. Therefore, the knitting method of the knitted fabric according to the first embodiment can knit the knitted fabric more efficiently than the knitting method of the conventional knitted fabric.

[0033] <Organization example 2> In knitting example 2, a part of the knitting process of the bind-off process will be described based on Figs. 3 and 4. The bind-off process is a process in which a double stitch is formed by transferring stitches in a narrow range of 3 stitches or less, and a new stitch is knitted on the double stitch. The bind-off process is a process that is frequently performed in any knitted fabric. The bind-off process in Figs. 3 and 4 is a bind-off process to prevent the end of a knitted fabric, such as a collar, from unraveling. In this bind-off process, the direction of the first racking is different from the direction of the second racking. Figs. 3 and 4 can be viewed in the same way as Fig. 2. In knitting example 2, a knitting example will be described using a flat knitting machine 5 in which the yarn feeder 8 in Fig. 1 is self-propelled. The self-propelled yarn feeder 8 is a yarn feeder 8 that can move independently of the carriage 6. In Figs. 3 and 4, the movement direction of the yarn feeder 8 is indicated by a solid arrow.

[0034] In S1 shown in column A of FIG. 3, the yarn feeder 8 is moved to the right and the leftmost stitch of BD is knitted. In S2, the leftmost stitch of BD is transferred to FU. In S3, BD and BU are racked one pitch to the left, and then the stitch of FU is overlapped with the leftmost stitch of BD. In S4, the yarn feeder 8 is moved to the left. In S5, BD and BU are racked one pitch to the right, and then the yarn feeder 8 is moved to the right and a stitch following the overlapping stitch in the wale direction is knitted. The first bind-off process is completed by steps S1 to S5.

[0035] In S6, the stitch knitted in S5 is transferred from BD to FU. In S7 in FIG. 4, BD and BU are racked one pitch to the left, and then the stitch of FU is overlapped with the stitch at the left end of BD. In S8, the yarn feeder 8 is moved leftward. In S9, BD and BU are racked one pitch to the right, and then the yarn feeder 8 is moved rightward to knit a stitch that continues in the wale direction of the overlapped stitch of BD. The second bind-off process is completed by S6 to S9. After S9, knitting is performed in the same manner as in S2 to S5. S10 shows the first step of the third bind-off process.

[0036] In the conventional knitting method of the knitted fabric shown in column B, five knitting courses are performed to execute the knitting process in column A. Specifically, in the conventional knitting method of the knitted fabric, two processes are performed in each knitting course.

[0037] 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. Specifically, in the first knitting course in column C of FIG. 3, S1 and S2 are performed. In the second knitting course, S3 to S6 are performed. In the third knitting course in column C of FIG. 4, S7 to S10 are performed. The second knitting course in column C of FIG. 3 and the third knitting course in column C of FIG. 4 are specific knitting courses in which two racking processes, two transfer processes, and one knit process are performed while the carriage is moved in one direction. More specifically, in the second knitting course in column C of FIG. 3, the first racking process, the first transfer process, the second racking process, the knit process, and the second transfer process are performed in this order while the carriage 6 is moved to the left. In this knitting example, the order of the second racking process and the knit process can be changed. In the first racking process, BD and BU are racked to the left. In the first transfer process, the stitches are transferred by the first cam system 6C. In the second racking step, BD and BU are racked to the right. In the knitting step, stitches are knitted by the second cam system 6B. In the second knitting course of this example, the yarn feeder 8 is moved in the same direction as the moving direction of the carriage 6 before the knitting step. This movement of the yarn feeder 8 corresponds to S4, and is a preparation step for moving the yarn feeder 8 to the right in S5 to perform the knitting step. The knitting step is performed by moving the yarn feeder 8 in the opposite direction to the moving direction of the carriage 6. In the second stitch transfer step, the stitches are transferred by the third cam system 6A.

[0038] In the third knitting course shown in column C of FIG. 4, the first racking process, the first stitch transfer process, the second racking process, the knit process, and the second stitch transfer process are performed in this order while the carriage 6 is moved to the right. In the case of this knitting example, the order of the second racking process and the knit process can be changed. In the first racking process, BD and BU are racked to the left. In the first stitch transfer process, stitches are transferred by the first cam system 6A. In the second racking process, BD and BU are racked to the right. In the knit process, stitches are knitted by the second cam system 6B. In the third knitting course of this example, the yarn feeder 8 is moved in the opposite direction to the moving direction of the carriage 6 before the knit process. The knit process is performed by moving the yarn feeder 8 in the same direction as the moving direction of the carriage 6. In the stitch transfer process, the stitches are transferred by the third cam system 6C.

[0039] As described above, the knitting method of the knitted fabric of the present invention shown in column C of Figs. 3 and 4 can knit a knitted fabric more efficiently than the knitting method of the conventional knitted fabric shown in column B.

[0040] <Program and storage medium> The knitting program that causes a flat knitting machine to perform the knitting method of the above-mentioned knitted fabric is a knitting program that causes a computer provided in the flat knitting machine 5 to control the flat knitting machine 5 (see Figure 1) to execute multiple knitting courses including a specific knitting course.

[0041] In the flat knitting machine 5, a cam provided on a carriage 6 traveling on the needle bed acts on a butt provided on a knitting needle, and the knitting needle advances and retreats along the needle groove of the needle bed to form a stitch. This flat knitting machine 5 is equipped with a needle selection mechanism that determines how each knitting needle is to move, a carriage control mechanism that controls the travel of the carriage 6 and the appearance and retraction of the cam, and a racking control mechanism that controls the racking of the needle bed. The knitting program issues commands to these mechanisms to control the movement of the carriage 6, the racking position of the needle bed, and the movement of each knitting needle, thereby causing the flat knitting machine to knit a fabric.

[0042] The storage medium that stores the knitting program may be installed in the knit design system or in the flat knitting machine. The storage medium may be a portable storage medium that transfers the knitting program created in the knit design system to the flat knitting machine. Examples of portable storage media include CD-ROMs, USB memory, and magnetic disks. Here, the knitted fabric design system is 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.

[0043] <Knit Design System> As shown in the functional block diagram of Figure 5, the knit design system 1 for knitted fabric, which creates the knitting program based on a user's design, includes an input unit 2, a creation unit 3, a memory 4, and a display unit 10. This knit design system 1 for knitted fabric is configured to automatically create the knitting program based on design data. Below, each component of the knit design system 1 will be briefly described, and then a procedure for the knit design system 1 for knitted fabric to create a knitting program based on information input by the user will be described.

[0044] The input unit 2 is used when the user edits the design data, and is configured in the form of a keyboard, mouse, scanner, digitizer, etc. The design data includes information on the shape and size of the knitted fabric to be knitted, information on the type of knitting yarn, information on the knitting units that make up the knitted fabric, information on the knitting code to be assigned to each knitting unit, etc. The knitting code information includes information on the position of the knitting unit and the knitting code to be assigned to that position.

[0045] Here, a knitting unit of the knitted fabric corresponds to one stitch in the knitted fabric. The knitting code assigned to each knitting unit represents the knitting operation to be performed by the flat knitting machine, for example, by a color, a number, a figure, or a combination of these. For example, a knitting code represented in red is defined as a knitting code that causes the flat knitting machine to knit a stitch. Of course, a single knitting code may define multiple knitting operations. For example, a knitting code that knits a stitch and then transfers the stitch may be included. These knitting codes are stored in memory 4, which will be described later.

[0046] The creation unit 3 creates a knitting program for the knitted fabric, and can be configured, for example, by a computer. The creation unit 3 includes a determination unit 31 that determines whether a specific knitting course can be executed based on design data, and a construction unit 32 that creates a knitting program based on the determination result of the determination unit 31.

[0047] The judgment unit 31 includes a first judgment unit 31A and a second judgment unit 31B. teeth , knitted fabric of All the steps for knitting are referred to, and a group of steps that constitute a specific knitting course is extracted from all the steps. For example, the following three groups of steps can be given. (1) A group of processes arranged in the following order: racking process, transfer process, racking process, transfer process. (2) A group of processes arranged in the following order: racking process, transfer process, racking process, knitting process, and transfer process. (3) A group of processes arranged in the following order: racking process, transfer process, knitting process, racking process, transfer process.

[0048] The second judgment unit 31B judges whether each process group extracted by the first judgment unit 31A can be executed while the carriage 6 is moving in one direction. Whether all processes included in one process group can be executed is determined based on, for example, the following information. The second judgment unit 31B judges whether the racking process can be executed at a timing when the cam systems 6A, 6B, 6C are not acting on the knitting needles based on the following information. (1) Types of cam systems 6A, 6B, 6C provided in the flat knitting machine 5. Types of cam systems include a cam system dedicated to the knitting process, a cam system dedicated to the transfer process, and a cam system capable of performing both the knitting process and the transfer process. (2) Number of cam systems 6A, 6B, 6C. (3) The moving speed of carriage 6. (4) The distance between the cam system that performs the first transfer process and the cam system that performs the second transfer process, and the distance between the cam system that performs the transfer process and the cam system that performs the knit process. (5) The position on the needle bed where the first and second transfer steps are performed.

[0049] The construction unit 32 creates a knitting program that sets racking, the operation of the knitting needles, the knitting yarn payout procedure, 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 judgment result of the judgment unit 31. If the above-mentioned process group is not extracted by the first judgment unit 31A, the construction unit 32 creates a knitting program consisting of a conventional knitting course. If the above-mentioned process group is extracted by the first judgment unit 31A, the construction unit 32 creates a knitting program so that a specific knitting course is executed for the process group for which the judgment result by the second judgment unit 31B is "YES". The construction unit 32 creates a knitting program so that a conventional knitting course is executed for the process group for which the judgment result by the second judgment 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 magnetic disk, or via wires, wirelessly, etc.

[0050] The memory 4 is a storage medium such as a solid state drive, a hard disk, etc. The memory 4 stores information such as design data and knitting codes.

[0051] The display unit 10 is for visually grasping information related to the design of the knitted fabric, and is not particularly limited. For example, a liquid crystal display can be used as the display unit 10. If a touch panel is used as the display unit 10, the display unit 10 can take on part of the role of the input unit 2.

[0052] The knit design system 1 having the above configuration automatically creates a knitting program for executing a plurality of knitting courses including at least one specific knitting course. According to this knitting program, it is possible to knit a knitted fabric more efficiently than before.

[0053] <Other embodiments> 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, a flat knitting machine equipped with four cam systems may be able to knit a knitted fabric more efficiently than a flat knitting machine equipped with three cam systems. In a flat knitting machine equipped with four cam systems, it is easy to ensure the distance between the cam system that executes the first stitch transfer process and the cam system that executes the second stitch transfer process, so there is a possibility that the number of specific knitting courses can be increased. In addition, with this flat knitting machine, there is a possibility that the number of empty courses where only the carriage is moved can be dramatically reduced.

[0054] The knitting method of the knitted fabric of the present invention can also be performed by a two-bed flat knitting machine. When using a two-bed flat knitting machine, the front knitted fabric section and the back knitted fabric section are knitted by needleless knitting. Needleless knitting means that knitting is performed with empty needles placed between adjacent stitches. The empty needles placed between adjacent stitches are used for transferring stitches.
