Problems to be solved by the invention

Due to the diversification of consumer demands, manufacturers desire to effectively knit small-lot and multi-variety knits. To meet this demand, a knitting method of a knitted fabric that can be knitted efficiently is required regardless of the type of knitted fabric.

An object of the present invention is to provide a knitting method of a knitted fabric excellent in knitting efficiency. An object of the present invention is to provide a knitting design system for creating a knitting program excellent in knitting efficiency. An object of the present invention is to provide a storage medium storing a knitting program excellent in knitting efficiency.

Means for solving the problems

The present inventors investigated all the steps for knitting one knitted fabric and the order of arrangement thereof. As a result, in any knitted fabric, there are many portions arranged in the order of the traverse step, the transfer step, the traverse step, and the transfer step in the process of knitting the knitted fabric. Conventionally, the shift step and the transfer step are performed in one knitting course. That is, the above four steps are performed in two knitting courses in which the carriage is reciprocated. The present inventors have found that by performing these operations while the carriage is moving in one direction, the knitting efficiency of the entire knitted fabric is significantly improved. The knitting method, knitting design system and storage medium of the knitted fabric of the present invention are listed below.

A knitting method of a knitted fabric of the present invention is a knitting method of knitting a knitted fabric by executing a plurality of knitting courses using a flatbed knitting machine including a first needle bed and a second needle bed which are relatively movable in a lateral direction and a carriage on which at least two cam systems are mounted, the knitting method including performing the first lateral movement step, the first transfer step, the second lateral movement step, and the second transfer step in this order while the carriage moves in one direction and passes through a knitting area in each of the specific knitting courses, the knitting area being an area where a series of stitches continuous in a knitting width direction are held.

Here, the series of stitches in the knitting area may be constituted by one knitting yarn, or may be stitches obtained by joining a plurality of stitch rows made of different knitting yarns. In addition, the carriage may pass through a plurality of knitting areas when moving in a specific knitting course. For example, in the knitting of a sweater, there is a case where the right sleeve, the front and back body panels, and the left sleeve are locked at positions separated in the longitudinal direction of the needle bed. In this case, the knitting area of the right sleeve, the knitting area of the front and rear body parts, and the knitting area of the left sleeve are separated in the knitting width direction, and therefore, they are considered to be different.

<2> as an embodiment of the knitting method of the knitted fabric of the present invention, there can be mentioned the following embodiment: the flat knitting machine includes a self-propelled yarn feeder, and performs a knitting process after the first traverse process in the specific knitting course.

A knitting design system of the present invention includes an input unit for a user to edit design data related to knitting of a knitted fabric and a creating unit for creating a knitting program readable by a computer provided on a flatbed knitting machine based on the design data, wherein the creating unit creates the knitting program for causing the computer to control the flatbed knitting machine so that the flatbed knitting machine executes the knitting method of the knitted fabric of <1> or <2 >.

<4> a storage medium of the present invention is a storage medium storing a knitting program readable by a computer provided on a flatbed knitting machine, wherein the knitting program causes the computer to control the flatbed knitting machine so that the flatbed knitting machine executes a knitting method of a knitted fabric <1> or <2 >.

[ Effect of the invention ]

In the knitting method of the knitted fabric of the present invention, since the 2 traversals and the 2 transfers are performed in one specific knitting course, the total number of knitting courses for finishing the knitted fabric becomes small. In addition, by executing a 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 remarkably improved.

When the flatbed knitting machine includes a self-propelled feeder, a knitting process may be included in a specific knitting course. By further performing the knitting step in one knitting course, the knitting efficiency of the knitted fabric can be further improved.

The invention provides a knitting design system, which can automatically make a knitting program capable of effectively knitting a knitted fabric based on knitting data input by a user. As described in the embodiment described later, the user only needs to input the knitting data to the knitting design system.

By using the knitting program stored in the storage medium of the present invention, the flat knitting machine can be caused to efficiently knit a knitted fabric.

Detailed Description

To implement the mode of the invention

Hereinafter, a knitting method, a knitting design system, and a storage medium of a knitted fabric according to the embodiments will be described with reference to the drawings.

< embodiment 1>

Example of knitting 1

In the present embodiment, an example of a knitting method of a knitted fabric of the present invention using a 4-bed flatbed knitting machine will be described first with reference to the drawings. As will be described later, the knitting method of the knitted fabric of the present invention may be performed by a 2-bed flat knitting machine.

The 4-needle bed flat knitting machine includes a lower front needle bed, a lower back needle bed, and an upper front needle bed and an upper back needle bed. Hereinafter, the lower front needle bed, the lower back needle bed, the upper front needle bed, and the upper back needle bed are respectively denoted as FD, BD, FU, and BU. In this example, FD and FU are the first needle bed, and BD and BU are the second needle bed. The FD and BD face each other. FU disposed above FD and BU disposed above BD face each other. The 4-needle bed flat knitting machine further includes a plurality of yarn feeders and a carriage. The relationship of the needle bed with the wire feeder and the carriage will be briefly described using the schematic diagram of fig. 1.

Fig. 1 is a schematic view of a part of the flatbed knitting machine 5 viewed from the FD side. In fig. 1, the FU is not illustrated. A carriage 6 provided on the flatbed knitting machine 5 reciprocates on a needle bed. The carriage 6 of this example includes 3

cam systems

6A,6B, and 6C. Each cam system is a general term for a plurality of cams provided at positions corresponding to FD, FU, BD, and BU in the carriage 6. Each cam system can perform any one of the knitting step and the transfer step. For example, in a cam system in which a knitting process is performed in a certain knitting course, a transfer process may be performed in another knitting course. The number of the triangulation systems may be 2 of the

triangulation systems

6A and 6B, or 4 of one triangulation system added to the triangulation systems 6A to 6C. Each wire feeder 8 is attached to be capable of running on a rail 7 disposed above the needle bed.

Fig. 2 illustrates an example in which two overlapping stitches are formed at a position separated within a narrow range of 10 loops, and here shows a part of a knitting process of shoulder threads for joining front and rear knitted fabrics forming a pullover sweater. Specifically, after the first traverse, a first overlapped coil is formed by the first transfer. Then, after the second traverse is performed in the same direction as the first traverse, a second lap stitch is formed by the second transfer.

The "S + number" shown in the left end column of the drawing sheet in fig. 2 is the number of the knitting step. The column a, second from the left, shows the formation state of the stitches in each knitting process. The black dots in column a indicate knitting needles, the Ω -marks indicate stitches, the inverted triangle marks indicate feeders 8, and the straight arrows indicate transfer. The third column B from the left shows knitting courses for executing the knitting process in column a in the conventional knitting method of knitted fabric. The right column C shows knitting courses for executing the knitting process in column a in the knitting method of the knitted fabric of this example. First, each knitting step is described with reference to column a.

In S1, the thread feeder 8 is moved leftward, and after a plurality of stitches are knitted in BD, the left 5 stitches of those stitches are transferred to FU.

In S2, after BD and BU are laterally moved 1 pitch in the left direction, the right three coils among the coils locked to FU are moved toward BD. By this transfer, the overlapping coil is formed on the BD.

In S3, after BD and BU are laterally moved 1 pitch in the left direction, the two coils locked to FU are moved toward BD. By this transfer, the overlapping coil is further formed on the BD.

In S4, after traversing BD and BU by 1 pitch in the right direction, the coil at the left end of FD is moved toward BD. By this transfer, the overlapping coil is further formed on the BD.

In S5, after the BD and BU are laterally moved rightward by 2 pitches, the coil at the right end of the FD is moved toward the BD. By this transfer, the overlapping coil is further formed on the BD.

Next, the structure of knitting courses in the knitting method of the conventional knitted fabric shown in column B will be described. The left-right direction arrow indicates the moving direction of the carriage 6 in fig. 1, the upward arrow indicates transfer from the front needle bed to the rear needle bed, and the downward arrow indicates transfer from the rear needle bed to the front needle bed. The two-dot chain line indicates the boundary of the

triangular systems

6A,6B,6C of fig. 1. The cam system on the side of the carriage 6 in the moving direction is a preceding cam system. "K" described in a portion corresponding to each cam system indicates a knitting process, "TR" indicates a transfer process, and "R" indicates a lateral shift process. The blank arrow at the upper portion of "R" indicates the direction of traverse.

As shown in column B, in the conventional knitting method of knitted fabric, 5 knitting courses are executed so as to correspond to 1 in each step.

Next, the structure of knitting courses in the knitting method of the knitted fabric of the embodiment shown in column C will be described. Column C looks the same as column B. As shown in column C, in the knitting method of the knitted fabric of the embodiment, the knitting process in column a is performed by three knitting courses. Specifically, S1 is executed in the first knitting course of column C. S2 and S3 are executed in the second knitting course. S4 and S5 are executed in the third knitting course. The second knitting course and the third knitting course are specific knitting courses in which 2 traversals and 2 transfers are performed while the carriage 6 (see fig. 1) is moved in one direction. More specifically, in the second knitting course, the first traverse step, the first transfer step, the second traverse step, and the second transfer step are sequentially performed while the carriage 6 is moved in the right direction. In the first traverse step, the BD and the BU are laterally moved in the left direction. In the first transfer step, the coil is transferred by the first cam system 6A in the traveling direction of the carriage 6. In the second traverse step, the BD and BU are traversed leftward. In the second transfer step, the coil is transferred by the third cam system 6C. Here, the second traverse process is performed at a timing when the

cam systems

6A,6B, and 6C do not act on the knitting needles. The second traverse step in the following description is also performed at a timing when the

cam systems

6A,6B, and 6C are not acting on the knitting needles.

In the third knitting course, the first traverse step, the first transfer step, the second traverse step, and the second transfer step are sequentially performed while the carriage 6 is moved in the left direction. In the first traverse step, the BD and BU are traversed to the right. In the first transfer step, the coil is transferred by the first cam system 6C in the traveling direction of the carriage 6. In the second traverse step, the BD and BU are traversed to the right. In the second transfer step, the coil is transferred by the third cam system 6A.

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 executing the knitting process in column a is smaller than that in the conventional knitting method of the knitted fabric shown in column B. Therefore, the knitting method of the knitted fabric of embodiment 1 can effectively knit the knitted fabric compared to the knitting method of the conventional knitted fabric.

Example of knitting 2

In knitting example 2, a part of a knitting process of the hidden stitch processing will be described with reference to fig. 3 and 4. The hidden stitch processing is processing of repeating forming of a double stitch by stitch transfer and knitting a new stitch on the double stitch in a narrow range of 3 or less turns. The hidden coil processing is a processing that can be performed at a high frequency in whatever knitted fabric. The hidden-coil processing of fig. 3 and 4 is, for example, hidden-coil processing for preventing the terminal end portion of a knitted fabric such as a collar from unraveling. The direction of the first traverse and the direction of the second traverse are different in this hidden-coil process. The views of fig. 3 and 4 are the same as those of fig. 2. In knitting example 2, a knitting example using a self-propelled flatbed knitting machine 5 using the yarn feeder 8 shown in fig. 1 will be described. The self-propelled wire feeder 8 is a wire feeder 8 that is movable independently of the carriage 6. In fig. 3, 4, the direction of movement of the wire feeder 8 is indicated by the general smearing arrow.

In S1 shown in column a of fig. 3, the yarn feeder 8 is moved rightward to knit the left end loop of the BD. In S2, the left coil of BD is transferred to FU. In S3, after BD and BU are laterally shifted by 1 pitch in the left direction, the coil of FU is overlapped on the left end coil of BD. In S4, the wire feeder 8 is moved in the left direction. In S5, after the BD and BU are shifted rightward by 1 pitch, the yarn feeder 8 is moved rightward to knit the continuous stitches in the wale direction of the overlapped stitches. The first hidden coil processing is completed by S1 to S5.

In S6, the stitch knitted in S5 is transferred from BD to FU. In S7 of fig. 4, after BD and BU are laterally shifted by 1 pitch in the left direction, the coil of FU is overlapped on the coil at the left end of BD. In S8, the wire feeder 8 is moved in the left direction. In S9, after the BD and BU are laterally moved rightward by 1 pitch, the thread feeder 8 is moved rightward to knit the stitches that are continuous in the wale direction of the overlapped stitches of the BD. The second hidden coil processing is ended by S6 to S9. After S9, knitting is performed in the same manner as S2 to S5. In S10, the first step of the third hidden coil processing is shown.

In the conventional knitting method of knitted fabric shown in column B, 5 knitting courses are performed to perform the knitting process in column a. Specifically, in the conventional knitting method of knitted fabric, two steps are performed in each knitting course.

Next, in the knitting method of the present invention shown in column C, the knitting process in column a is performed by 3 knitting courses. Specifically, S1 and S2 are executed in the first knitting course in column C of fig. 3. In the second knitting course, S3 to S6 are performed. In the third knitting course in the column C of fig. 4, S7 to S10 are executed. 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 the 2-time traversing step, the 2-time transferring step, and the 1-time knitting step are performed while the carriage is moved in one direction. More specifically, in the second knitting course in the column C of fig. 3, the first traverse step, the first transfer step, the second traverse step, the knitting step, and the second transfer step are sequentially performed while the carriage 6 is moved in the left direction. In the case of this knitting example, the order of the second traverse step and the knitting step may be changed. In the first traverse step, the BD and BU are traversed in the left direction. In the first transfer step, the first cam system 6C transfers the coil. In the second traverse step, the BD and BU are traversed to the right. In the knitting step, the second cam system 6B knits the stitch. In the second knitting course of this example, the yarn feeder 8 is moved in advance in the same direction as the traveling direction of the carriage 6 before the knitting process. The movement of the yarn feeder 8 corresponds to S4, and is a preparatory step for moving the yarn feeder 8 in the right direction to perform a knitting step in S5. The knitting process is performed by moving the yarn feeder 8 in a direction opposite to the traveling direction of the carriage 6. In the second transfer step, the coil is transferred by the third cam system 6A.

In the third knitting course shown in the column C of fig. 4, the first lateral shift step, the first transfer step, the second lateral shift step, the knitting step, and the second transfer step are sequentially performed while the carriage 6 is moved in the right direction. In the case of this knitting example, the order of the second traverse step and the knitting step may be changed. In the first traverse step, the BD and BU are traversed in the left direction. In the first transfer step, the first cam system 6A transfers the coil. In the second traverse step, the BD and the BU are traversed in the right direction. In the knitting step, the second cam system 6B knits the stitch. In the third knitting course of this example, the yarn feeder 8 is moved in advance in the direction opposite to the traveling direction of the carriage 6 before the knitting step. The knitting step is performed by moving the yarn feeder 8 in the same direction as the traveling direction of the carriage 6. In the transfer step, the coil is transferred by the third cam system 6C.

As described above, the knitting method of the knitted fabric of the present invention shown in column C of fig. 3 and 4 can effectively knit the knitted fabric, compared with the knitting method of the conventional knitted fabric shown in column B.

Knitting program and storage medium

The knitting program to be executed by the flat knitting machine in the knitting method of the knitted fabric is a knitting program to cause a computer provided in the flat knitting machine 5 to control the flat knitting machine 5 so that the flat knitting machine 5 (see fig. 1) executes a plurality of knitting courses including a specific knitting course.

In the flatbed knitting machine 5, a cam provided on a carriage 6 that runs on a needle bed acts on a butt provided on a knitting needle, and a stitch is formed by the knitting needle advancing and retreating along a needle groove of the needle bed. The flat knitting machine 5 is provided with a needle selection mechanism for determining which knitting needle is to be operated, a carriage control mechanism for controlling the running of the carriage 6 and the advancing and retracting of the cams, and a lateral movement control mechanism for controlling the lateral movement of the needle bed. The knitting program instructs these mechanisms to control the movement of the carriage 6, the lateral movement position of the needle bed, the operation of each knitting needle, and the like, so that the flat knitting machine can knit the knitted fabric.

The storage medium storing the knitting program may be mounted on the knitting design system or may be mounted on the flatbed knitting machine. The storage medium may be a removable storage medium for transferring the knitting program created by the knitting design system to the flatbed knitting machine. Examples of the removable storage medium include a CD-ROM, a USB memory, and a magnetic disk. Here, the knitting fabric design system refers to a system in which a user designs a knitting fabric on a screen and creates a knitting program for operating a flat knitting machine based on the design of the user.

Knitting design System

As shown in the functional block diagram of fig. 5, a knitting design system 1 for creating a knitted fabric of the knitting program based on design by a user includes an input unit 2, a creation unit 3, a memory 4, and a display unit 10. The knitting design system 1 of the knitted fabric is configured to automatically create the knitting program based on design data. Next, a procedure in which the knitting design system 1 of the knitted fabric creates a knitting program based on information input by the user will be described.

The input unit 2 is a part used by a user to edit design data, and is configured by a keyboard, a mouse, a scanner, a digitizer, and the like. The design data includes information on what shape and size of knitted fabric is knitted, information on the type of knitting yarn, information on knitting units constituting the knitted fabric, information on knitting codes assigned to the respective knitting units, and the like. The information of the knitting code includes the position of the knitting unit and the information of the knitting code assigned to the position.

Here, the knitting unit of the knitted fabric is a unit corresponding to one amount of stitches in the knitted fabric. The knitting code assigned to each knitting unit indicates, for example, a color, a numeral, a figure, or a combination thereof, a knitting operation to be performed by the flatbed knitting machine. For example, a knitting code indicated by red is defined as a knitting code for causing a flatbed knitting machine to knit a front stitch. Of course, a plurality of knitting operations may be defined by one knitting code. For example, there is a knitting code for transferring a stitch after knitting the stitch. These knitting codes are stored in a memory 4 described later.

The creation unit 3 is a part for creating a knitting program of a knitted fabric, and can be constituted by a computer, for example. The creating unit 3 includes a determining unit 31 for determining whether or not to execute a specific knitting course based on design data, and a constructing unit 32 for creating a knitting program based on the determination result of the determining unit 31.

The judgment unit 31 includes a first judgment unit 31A and a second judgment unit 31B. The first judging unit 31A refers to all steps used for knitting of the knitted fabric, and extracts a step group constituting a specific knitting course from all the steps. The process group includes, for example, the following three.

(1) And a process group arranged in the order of the transverse moving process, the transferring process, the transverse moving process and the transferring process.

(2) And the process groups are arranged according to the sequence of the transverse moving process, the loop transferring process, the transverse moving process, the weaving process and the loop transferring process.

(3) And a step group arranged in the order of the traversing step, the transferring step, the knitting step, the traversing step and the transferring step.

The second determination unit 31B determines whether or not each process group extracted by the first determination unit 31A is executable while the carriage 6 is moved in one direction. Whether or not all steps included in one step group can be executed is determined based on the following information, for example. The second determination unit 31B determines whether or not the traverse process can be executed at a timing when the

cam systems

6A,6B, and 6C are not acting on the knitting needles, based on the following information and the like

(1) The types of

cam systems

6A,6B, and 6C provided in the flatbed knitting machine 5. The types of cam systems include a cam system dedicated to a knitting process, a cam system dedicated to a transfer process, and a cam system capable of executing both the knitting process and the transfer process.

(2) Number of

triangulation systems

6A,6B, 6C.

(3) The moving speed of the carriage 6.

(4) The distance between the cam system for executing the first transfer process and the cam system for executing the second transfer process, and the distance between the cam system for executing the transfer process and the cam system for executing the knitting process.

(5) The first transfer step and the second transfer step are performed on the needle bed.

The construction section 32 creates a knitting program in which the traverse, the operation of the knitting needles, the yarn feeding step, and the like are set based on the design data. In this example, the construction section 32 creates a knitting program including a specific knitting course based on the determination result of the determination section 31. The construction unit 32 creates a knitting program composed of a conventional knitting course when the above-described process group is not extracted by the first judgment unit 31A. When the above-described process group is extracted by the first judgment unit 31A, the construction unit 32 creates a knitting program so as to execute a specific knitting course for the process group whose judgment result by the second judgment unit 31B is "YES". The construction unit 32 creates a knitting program so as to execute a conventional knitting course for the step group whose determination result by the second determination unit 31B is "NO". The knitting program created by the construction unit 32 is sent to the flatbed knitting machine 5 via a recording medium such as a magnetic disk, wired, wireless, or the like.

The memory 4 is a storage medium such as a solid-state drive, a hard disk, or the like. In the memory 4, information such as design data and a knitting code is stored.

The display unit 10 is not particularly limited to visually grasp information related to the design of the knitted fabric. The display unit 10 may be, for example, a liquid crystal display. If a touch panel is used as the display unit 10, the display unit 10 can be made to function as a part of the input unit 2.

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 procedure, the knitted fabric can be knitted more efficiently than in the past.

< other embodiment >

The knitting method of the knitted fabric of the present invention may be performed by a flat knitting machine equipped with 2 or 4 cam systems. In particular, if the flat knitting machine is provided with 4 cam systems, the knitted fabric may be knitted more efficiently than the flat knitting machine provided with 3 cam systems. In the flat knitting machine including 4 cam systems, since it is easy to secure a distance between the cam system for executing the first transfer step and the cam system for executing the second transfer step, there is a possibility that the number of specific knitting courses can be increased. In addition, in this flatbed knitting machine, there is a possibility that the number of empty courses that perform only the movement of the carriage is significantly reduced.

The knitting method of the knitted fabric of the present invention can be performed by a 2-bed flat knitting machine. When a 2-bed flat knitting machine is used, the front knitted fabric portion and the rear knitted fabric portion are knitted by a draw knitting. The needle drawing knitting is knitting performed in a state where empty needles are arranged between adjacent stitches. The empty needle disposed between the adjacent stitches can be used for transferring the stitches.
