The knitting method of the rope pattern that replaces the stitches at once, and the rope pattern that divides both stitch rows into a plurality of groups and gradually moves each county to gradually change the position of the first stitch row and the second stitch row The knitting method is known.

Japanese Patent No. 3887410

  However, the conventional rope pattern knitting method may not be applied depending on the number of stitches of the first stitch row and the second stitch row constituting the rope pattern and the structure of the base knitted fabric portion other than the rope pattern. is there. For example, when the number of stitches in each stitch row is four or more, the rope pattern knitting method in which the first stitch row and the second stitch row are replaced at a time may cause yarn breakage. In addition, when forming a texture pattern on the base knitted fabric portion, there are cases where knitting of the rope pattern and knitting of the texture pattern of the base knitted fabric portion cannot be performed simultaneously due to differences in racking or the like. Thus, the conventional rope pattern knitting methods have advantages and disadvantages, respectively, and it is necessary for the user who designs the knitted fabric to select an optimal rope pattern knitting method as necessary. In order to reduce such a burden on the user, a rope pattern knitting method that can be used universally without being limited by the design pattern of the base knitted fabric portion or the number of stitches in the stitch row to be crossed is required. .

  The present invention has been made in view of the above circumstances, and one of its purposes is to provide a rope pattern knitting method having excellent versatility. Another object of the present invention is to provide a knitted fabric design system for creating a knitting program for causing a flat knitting machine to execute the above-described versatile knitting method of a rope pattern and a storage medium storing the knitting program. There is.

The present invention uses a flat knitting machine including at least a first needle bed and a second needle bed facing in the front-rear direction, in the length direction of the needle bed, one side base portion, a first stitch row, a second stitch row, The present invention relates to a rope knitting method for forming a rope pattern on a knitted fabric by switching the position of the first stitch row and the position of the second stitch row from a state in which the other side base portions are arranged in order. In the rope pattern knitting method of the present invention, when the region where the first stitch row and the second stitch row are arranged in the first needle bed is an intersection region, the following steps α to δ are performed.
[Step α] ... With the second stitch row deposited on the second needle bed, the first stitch row is moved to the other base side in the intersecting region, and the second stitch row is knitted. Without knitting, the one side base portion, the first stitch row, and the other side base portion are knitted at least once.
[Step β]... A plurality of stitches constituting the first stitch row are divided into one side group near the one side base portion and another side group near the other side base portion, and the other side in the intersection region The other side group is moved to the end on the base part side, and at least a part of the stitches of the one side group is moved to the side of the other side base part, and between the other side group and the one side group. And empty needles are formed within the knitting width of the one side group.
[Step γ]... Each stitch in the second stitch row is distributed to the empty needles in the intersecting region, and the one side base portion, the second stitch row, and the other side base are formed without knitting the first stitch row. Organize the department.
[Step δ] The stitches of the first stitch row in the mixed region where the stitches of the first stitch row and the stitches of the second stitch row are mixed are moved to the other base portion side, and the mixed region The first stitch row, the second stitch row, and the other base portion are moved without moving the stitches of the second stitch row to the one side base portion side and knitting the first stitch row. Is repeated until the mixture of the stitches in the first stitch row and the stitches in the second stitch row is eliminated. The mixed region is a region where the first stitch row and the second stitch row overlap in the length direction of the needle bed, and the first stitch row and the second stitch row overlap with each other from the end near the other base portion. This refers to the region up to the end near the one side base portion of the first stitch row (see S7 and S9 in FIG. 2 described later).

  As a method for knitting the rope handle of the present invention, the first base portion, the second stitch row, and the other base portion are knitted without knitting the first stitch row before performing the step α. The form which performs process (epsilon) which cut | disconnects connection with said 1st stitch row | line | column and said 2nd stitch row | line can be mentioned.

  As the rope knitting method of the present invention, when the second stitch row is moved toward the one-side base portion in the step γ, the end stitches near the other base portion in the second stitch row are arranged. A mode in which the grouping in the step β is performed so that the movement distance of the needles is 2 to 4 stitches. In the case of total needle knitting, this configuration is synonymous with the number of stitches in the other side group in the step β being 2 to 4.

  The present invention is a computer provided in a flat knitting machine including an input unit for a user to input knitting information related to knitting of a knitted fabric, and a first needle bed and a second needle bed facing each other based on the knitting information. The present invention relates to a knitted fabric design system including a knitting program creation unit that creates a readable knitting program. This knitted fabric design system of the present invention determines knitting conditions for carrying out the rope knitting method of the present invention based on the rope pattern related information related to the knitting of the rope pattern among the knitting information. A knitting condition determination unit is provided. The knitting program creating unit provided in the knitted fabric design system of the present invention is configured to cause the computer to execute the rope knitting method based on the knitting conditions determined by the knitting condition determining unit. Create a knitting program that controls the flat knitting machine.

  The present invention relates to a storage medium that stores a computer-readable knitting program provided in a flat knitting machine including a first needle bed and a second needle bed facing each other in the front-rear direction. The knitting program stored in the storage medium of the present invention is a knitting program that causes the computer to control the flat knitting machine so as to cause the flat knitting machine to execute the rope pattern knitting method of the present invention.

  According to the rope pattern knitting method of the present invention, thread breakage hardly occurs when the position of the first stitch row and the position of the second stitch row are interchanged. This is because the stitches are gradually moved within a range where yarn breakage does not occur both when the stitches of the first stitch row are moved and when the stitches of the second stitch row are moved. Details thereof will be described in the embodiment.

  The rope pattern knitting method of the present invention can be used universally regardless of the texture pattern of the base knitted fabric portion. Until the knitting of the rope pattern is completed, the knitting of the first stitch row and the knitting of the second stitch row are performed only in the intersecting region of the first needle bed. This is because even when a texture pattern that can be knitted only in a racked state is formed in the base knitted fabric portion, the stitches constituting the rope pattern can be knitted on the first needle bed regardless of the racking state of the second needle bed.

  Furthermore, according to the knitting method of the rope pattern of the present invention for performing the step ε, since the connection between the first stitch row and the second stitch row, and the connection between the first stitch row and the one side base portion can be broken, Yarn breakage when moving the first stitch row can be suppressed.

  If the movement distance of the end stitch near the other base portion in the second stitch row is 2 stitches or more and 4 stitches or less, when the stitches of the second stitch row are allocated in step γ, It is possible to suppress breakage of the crossover yarn connecting the other side base portion.

  According to the knitted fabric design system of the present invention, it is possible to create a knitting program capable of knitting a rope pattern that is not restricted by the tissue pattern of the base knitted fabric portion into the knitted fabric. As shown in the embodiment described later, the user only has to specify the position at which the knitted pattern is knitted on the knitted fabric design system, and the knitted fabric design system automatically executes the knitting program based on the designation by the user. create.

  By knitting the knitted fabric with a flat knitting machine using the knitting program stored in the storage medium of the present invention, a rope pattern that is not restricted by the texture pattern of the base knitted fabric portion can be knitted into the knitted fabric.

It is a knitting process figure which shows the first half part of the knitting process of a rope handle shown in embodiment. It is a knitting process figure which shows the latter half part of the knitting process of the rope handle shown to embodiment. It is a functional block diagram of the knitted fabric design system shown in the embodiment.

  A front needle bed (hereinafter referred to as FB) and a rear needle bed (hereinafter referred to as BB) that extend in the left-right direction and face each other in the front-rear direction, and a yarn feeder for supplying knitting yarn are provided. An example of knitting using a two-bed flat knitting machine capable of transferring stitches will be described. Of course, the flat knitting machine to be used is not limited to the two-bed flat knitting machine, and may be a four-bed flat knitting machine, for example.

<Rope pattern knitting method>
In this embodiment, as an example of a rope pattern knitting method, a rope pattern (6 × 6 rope pattern) in which both the first stitch row and the second stitch row for swapping the left and right positions in the knitted fabric are composed of six stitches. An example of this will be described with reference to FIGS. Note that the number of stitches in each stitch row is not particularly limited, and may be, for example, a 4 × 4 to 12 × 12 rope pattern. The number of stitches in the first stitch row may be different from the number of stitches in the second stitch row (for example, 4 × 6 rope pattern). The rope pattern knitting method of this example can also be applied to a tubular knitted fabric.

"Alphabet + number" on the left column of FIG. 1 and 2 indicates the number of the knitting process, are shown organized state in needle bed in the right column. The capital letter in the figure indicates the position of the knitting needle, the arrow indicates the direction of transfer, and the triangle indicates the yarn feeder 8. Further, the stitches of the one side base part b1 and the other side base part b2 which are base knitted fabric parts other than the rope pattern are circle marks, the stitches of the first stitch row 1 are diamond marks, and the stitches of the second stitch row 2 are pentagon marks. It shows with. The operations actually performed in each process are indicated by bold lines and filled. 1 and 2, the BB racking operation is omitted.

  In S0, the yarn feeder 8 is moved to the right in the drawing, and the one side base portion b1, the first stitch row 1, the second stitch row 2, and the other side base portion b2 arranged in the length direction of FB and BB are knitted. (The base portions b1 and b2 are also stitch rows made up of a plurality of stitches). The one-side base portion b1 is locked to the knitting needles Q and R of the BB and the knitting needles S and T of the FB. The first stitch row 1 is locked to the knitting needles K to P of the FB, and the second stitch row 2 is locked to the knitting needles E to J of the FB. The other side base part b2 is locked to the knitting needles A and B of the FB and the knitting needles C and D of the BB.

Here, the stitches on the side where the rope pattern is formed in both base portions b1 and b2 are knitted with BB, and the back stitch is used to lift the rope pattern from the base knitted fabric portion. Further, this back stitch formation, and the base portion b1, b2, and stitch row 1 and 2 constituting a rope pattern, floating yarn becomes long connecting, when moving the stitch row 1 and 2 constituting a rope handle yarn breakage is suppressed crossover yarn.

  By changing the position of the first stitch row 1 and the position of the second stitch row 2 on the knitting needles E to P from the state shown in S0, a base constituted by the one-side base portion b1 and the other-side base portion b2 A rope pattern is formed within the knitting width of the knitted fabric portion. When forming the rope pattern, both stitch rows 1 and 2 are crossed so that the first stitch row 1 is on the front side of the second stitch row 2.

  Here, in the knitting process shown below, the knitting of the first stitch row 1 and the knitting of the second stitch row 2 are performed in the region where the first stitch row 1 and the second stitch row 2 are aligned in the FB (that is, the knitting needle E of the FB). ˜P)) only. This region is called a crossing region, and is shown surrounded by a broken line in the drawing.

  In S1, the yarn feeder 8 is moved leftward, and the first base row b1, the second stitch row 2, and the other base portion b2 are knitted without knitting the first stitch row 1 (corresponding to step ε). . By this S1, the connection between the first stitch row 1 and the second stitch row 2 and the connection between the first stitch row 1 and the one-side base part b1 are broken, and the first stitch row 1 is moved in the subsequent steps. It is possible to prevent thread breakage at the time. Further, S1 also has an effect of preventing yarn breakage when the second stitch row 2 is moved in the subsequent process.

  In S2, the first stitch row 1 locked to the knitting needles K to P of the FB is moved to the knitting needles K to P of the BB, and the second stitch row 2 locked to the knitting needles E to J of the FB is moved to the BB. Move to knitting needles E-J. This S2 is preparation for switching the position of the first stitch row 1 and the position of the second stitch row 2.

  In the next S3 to S5 shown in FIG. 2, the first stitch row 1 is moved by one stitch toward the other side base b2, and the stitch rows b1, 1, b2 other than the second stitch row 2 are knitted. Repeat three times (corresponding to step α). The movement and knitting of the first stitch row 1 are carried out in such a manner that the end stitch near the other base portion b2 of the first stitch row 1 (the stitch of the knitting needle J of the FB in S3) is the final movement position of the first stitch row. It is good to repeat until it moves to the position (position of the knitting needles G to I of the FB) 2 to 4 stitches away from (the position of the knitting needle E of the FB). The one-time movement distance of the first stitch row 1 is not limited to one stitch as in the above example, and the knitting yarn connecting the first stitch row 1 and the one-side base portion b1 cannot be cut. It should be a degree. For example, when the knitting yarn used for knitting is a normal knitting yarn (non-elastic knitting yarn), the moving distance of the first stitch row 1 can be about 2 to 3 stitches. However, when the knitting yarn used for knitting is an elastic knitting yarn, the moving distance of the first stitch row 1 can be four stitches or more.

  In S3 which is a part of the process α, the first stitch row 1 which is locked to the knitting needles K to P of the BB using racking and transfer while the second stitch row 2 is left in the BB is set to FB. The knitting needles J to O are moved. That is, the first stitch row 1 is moved by one stitch from the state of S1 in FIG. 1 to the other side base portion b2. Furthermore, in S3, the yarn feeder 8 is moved rightward, and the one side base portion b1, the first stitch row 1, and the other side base portion b2 are continuously knitted without knitting the second stitch row 2. . By this movement and knitting, the connecting yarn 3 connecting the first stitch row 1 and the one-side base portion b1 becomes long, and it becomes easy to perform the next S4.

  Here, the stitch rows b1, 1, and b2 may be knitted for at least one course without moving the first stitch row 1 after S3. When the number of courses in the first stitch row 1 (the number of steps in the wale direction) is larger than the number of courses in the second stitch row 2 to be described later, the shape of the rope pattern is easily arranged.

  In S4 and S5, as in S3, the first stitch row 1 is moved by one stitch toward the other side base portion b2 and the second stitch row 2 is not knitted and The first stitch row 1 and the other side base portion b2 are knitted.

  In S6, the first stitch row 1 in S5 is divided into one side group g1 near the one side base part b1 and another side group g2 near the other side base part b2, and each group g1, g2 is divided into the other side base of the FB. Move to the knitting needle closer to the part b2 (corresponding to step β). At that time, the other side group g2 is moved to the left end of the intersecting region, and the stitches constituting the one side group g1 are distributed to the knitting needles closer to the one side base part b1 than the other side group g2. When the one side group g1 is distributed, empty needles are formed between the other side group g2 and the one side group g1 and within the knitting width of the one side group g1 (for the former, the knitting needle H of the FB For the latter, see FB knitting needles J and L).

  Here, the number of stitches assigned to each of the groups g1 and g2 is determined by determining whether or not the connecting yarn 3 connecting the second stitch row 2 and the other side base portion b2 is cut when the second stitch row 2 is moved in the next S7. Decide within a range. Specifically, among the stitches constituting the first stitch row 1, about 1 to 3 stitches near the other side base portion b2 are set as the other side group g2, and the remaining stitches are set as the one side group g1. For example, even if the first stitch row 1 is composed of 12 stitches, the other side group g2 is made up of about 2 to 4 stitches, and the one side group g1 is made up of about 10 to 8 stitches. However, when the knitted fabric is knitted with the elastic knitting yarn, the number of stitches of the other side group g2 can be four or more.

  In order to move the stitch of S6, the BB is racked in the left direction so that the blank needle of BB is arranged at a position facing the first stitch row 1. Next, the stitches of the first stitch row 1 locked to the knitting needles H to M of the FB in S5 are deposited in the BB. Then, it is preferable to sequentially return the stitches deposited in the BB to the FB while racking the BB in the left direction.

  In S7, the respective stitches constituting the second stitch row 2 are moved to the empty needles in the intersecting area of the FB surrounded by the broken line, and the stitch rows b2, 2, b1 other than the first stitch row 1 are knitted (step γ). Equivalent). The empty needles in the intersecting region are empty needles formed in the FB through the processes α and β. In this example, the empty needles in which the knitting needles N, O, and P of the FB are formed in the process α. The knitting needles H, J, and L of the FB are needles formed in the process β. When the second stitch row 2 is moved, the arrangement order of the stitches of the second stitch row 2 in the needle bed length direction is not changed. In this example, among the stitches of the second stitch row 2 locked to the BB, the stitch of the knitting needle E, the stitch of the knitting needle F, and the stitch of the knitting needle G are respectively the knitting needle H, the knitting needle J, and the knitting needle of the FB. The stitches of the knitting needles H, I, and J of the BB are moved to the knitting needles N, O, and P of the FB, respectively.

  Here, in the second stitch row 2, the end stitch near the other side base portion b2 extends from the knitting needle E of BB to the knitting needle H of FB (empty needle between the one side group g1 and the other side group g2). The needle bed has moved three needles in the length direction of the needle bed. If the movement is about three stitches, there is a low possibility that the connecting yarn 3 connecting the second stitch row 2 and the other side base portion b2 will be cut. Of the stitches in the second stitch row 2, the end stitch near the one-side base portion b1 has moved from the knitting needle J of the BB to the knitting needle P of the FB by six stitches in the length direction of the needle bed. As shown in S1 of FIG. 1, the end stitch is connected to the one-side base portion b1, and the connecting yarn connecting the end stitch and the one-side base portion b1 is very long. Since the movement direction of the end stitch is a direction in which the distance between the end stitch and the one-side base portion b1 is shortened, there is no fear of yarn breakage.

In the next S8 to S11, each of the first stitch row 1 stitch and the first stitch row 1 stitch of the stitch second stitch row 2 is in mixed area mixed and second stitch row 2 stitches, other The movement to the side base part b2 side and the side of the one side base part b1 and the knitting of the second stitch row 2 are repeated until mixing of the stitches of both stitch rows 1 and 2 is eliminated (corresponding to step δ). ). When knitting the second stitch row 2, the stitch rows b1, 2, b2 other than the first stitch row 1 are knitted.

  In S8 which is a part of the process δ, the knitting needles H to M of the FB in the mixed region 4 shown in S7 are moved to the knitting needles H to M of the BB. The mixed region 4 is an end portion near the one-side base portion b1 of the first stitch row 1 (see the knitting needle M) from an end portion (see the knitting needle H) near the other base portion b2 of the second stitch row 2 after the end of S7. It is an area up to.

  In S9, using the racking and transfer, the stitches of the first stitch row 1 locked to the knitting needles I, K, M of the BB are moved to the knitting needles H, J, L of the FB, and the knitting needles H, BB of the BB are moved. The stitches of the second stitch row 2 locked to J, L are moved to the knitting needles I, K, M of the FB. Further, in S9, the yarn feeder 8 is moved rightward, and the other side base portion b2, the second stitch row 2, and the one side base portion b1 are continuously knitted without knitting the first stitch row 1. .

By the above S8 and S9, the mixing of the stitches of the first stitch row 1 and the stitches of the second stitch row 2 is partially eliminated, and the knitting needles I to L of the FB become the new mixed region 5. Therefore, in S10, the knitting needles I to L of the FB in the mixed area 5 are moved to the knitting needles I to L of the BB.

  In S11, the stitches of the first stitch row 1 locked to the knitting needles J and L of the BB are moved to the knitting needles I and J of the FB and the second stitch row 2 locked to the knitting needles I and K of the BB. The stitch is moved to the knitting needles K and L of the FB. Furthermore, in S11, the yarn feeder 8 is moved leftward, and the other side base portion b2, the second stitch row 2, and the one side base portion b1 are knitted without knitting the first stitch row 1. By this S10, S11, the mixture of the stitches of both stitch rows 1 and 2 is eliminated, and the position of the first stitch row 1 and the position of the second stitch row 2 are interchanged, that is, the first stitch row 1 is the second. A rope pattern crossing the front side of the stitch row 2 is formed.

  Thereafter, if the rope pattern is further knitted, S1 to S11 in FIGS. Further, the knitting similar to S1 to S11 can be performed by defining the one side base portion b1, the first stitch row 1, the second stitch row 2, and the other side base portion b2 in order from the left side of the drawing. In that case, it is possible to form a rope pattern in which the stitch rows of the knitting needles E to J of the FB in S0 of FIG. 1 are arranged on the surface side of the knitted fabric.

  According to the knitting process described above, it is possible to avoid yarn breakage when the position of the first stitch row 1 and the position of the second stitch row 2 are switched. This is because of the two stitches connected by the crossover yarn, when one of the stitches is moved in the direction in which the crossover yarn extends, the movement distance is at most 4 stitches or less.

  In the knitting step, the first stitch row 1 and the second stitch row 2 are knitted only within the crossing area of the FB surrounded by the broken line until the knitting of the rope pattern is completed. Even when a texture pattern that can be knitted only in a state where the BB is racked is formed on the base knitted fabric portion (base portions b1, b2), the stitches constituting the rope pattern can be knitted with the FB regardless of the racking state of the BB. That is, the rope pattern knitting method shown in the embodiment has the versatility that a rope pattern can be formed no matter what kind of structure pattern is provided on the base knitted fabric portion outside the intersecting region.

  Furthermore, in the knitting process, the second stitch row hidden behind the first stitch row consisting of the front stitches is also a front stitch, so the organization of the first stitch row portion and the second stitch row portion in the rope pattern is unified. There is a feeling and the appearance of the rope pattern is improved.

<Knitting program and storage medium>
The knitting program for causing the flat knitting machine to perform the above-mentioned rope pattern knitting method is a knitting program for causing the computer provided in the flat knitting machine to control the flat knitting machine so as to cause the flat knitting machine to execute the following steps. By executing the following steps, the position of the first stitch row 1 and the position of the second stitch row 2 arranged between the one-side base portion b1 and the other-side base portion b2 shown in S0 of FIG. The replaced rope pattern can be formed on the knitted fabric.

  Here, in the flat knitting machine, a cam provided on a carriage traveling on the needle bed acts on a bat provided on the 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 includes a needle selection mechanism that determines which knitting needles are to be moved, a carriage control mechanism that controls the carriage travel and cam protrusion, and a racking control mechanism that controls the needle bed racking. And are equipped. The knitting program issues a command to these mechanisms to control the racking position of the needle bed and the movement of each knitting needle, thereby realizing the knitting in the following steps.

  The region where the first stitch row 1 and the second stitch row 2 are aligned in the FB is defined as an intersection region, and the second stitch row 2 is deposited in the BB, and the first stitch row 1 is placed on the other base portion b2 in the intersection region. Step 1 in which the one side base part b1, the first stitch line 1 and the other side base part b2 are knitted at least once without moving to the side and knitting the second stitch line 2.

A plurality of stitches constituting the first stitch row 1 are divided into a one side group g1 near the one side base portion b1 and another side group g2 near the other side base portion b2, and the other side group g2 up to the end of the intersecting region. And a part of the stitches of the one side group g1 are moved to the side of the other side base portion b2, so that they are empty between the other side group g2 and the one side group g1 and within the knitting width of the one side group g1. Step 2 of forming the needle.

  Step 3 of allocating the respective stitches of the second stitch row 2 to the empty needles in the intersecting region and knitting the first side base portion b1, the second stitch row 2 and the other side base portion b2 without knitting the first stitch row 1. .

  The stitches of the first stitch row 1 in the mixed regions 4 and 5 where the stitches of the first stitch row 1 and the stitches of the second stitch row 2 are mixed are moved to the other side base portion b2 side, and the mixed regions 4, 5 Without moving the stitches of the second stitch row 2 to the side of the one-side base portion b1, and knitting the first stitch row 1, the one-side base portion b1, the second stitch row 2, and the other-side base portion b2 Step 4 is repeated until the mixture of the stitches in the first stitch row 1 and the stitches in the second stitch row 2 is eliminated.

  The storage medium for storing the knitting program may be in a form mounted in a knitted fabric design system, may be in a form mounted in a flat knitting machine, or a knitting program created in the knitted fabric design system It may be in the form of a portable storage medium such as a CD ROM, a USB memory, or a magnetic disk that is transferred to the flat knitting machine. Here, the design system of the knitted fabric is a system that creates a knitting program for operating the flat knitting machine based on the design of the user by designing the knitted fabric on the screen (for example, (See Japanese Patent No. 2916990).

The knitting condition determining unit 21 determines a knitting condition for implementing the knitting method of the rope handle of the present invention, that is, the knitting condition of each step of the knitting program described above, based on the rope related information. Examples of the knitting conditions to be determined include the following five.
(1) A one-time movement distance of the first stitch row 1 in Step 1.
(2) The number of times the movement and knitting of the first stitch row 1 in step 1 are repeated.
(3)... Method of grouping the first stitch row 1 in step 2 (how many stitches each of the one side group g1 and the other side group g2 are composed of).
(4) ... Location where the empty needle is formed in step 2.
(5) A movement pattern of the first stitch row 1 and the second stitch row 2 for eliminating the mixture of the stitches of the first stitch row 1 and the second stitch row 2 in Step 4.

  In the knitted fabric design system 100 of this example, a plurality of the knitting conditions (1) to (5) are prepared, and the knitting conditions are stored in a memory 30 described later. Each knitting condition is set in advance according to the type of knitting yarn and the number of stitches constituting the first stitch row 1 and the second stitch row 2 (that is, the rope pattern related information). For example, when the number of stitches in both stitch rows 1 and 2 is four, the knitting condition is “X”, and when the number of stitches in both stitch rows 1 and 2 is five, the knitting condition is “Y”. A plurality of knitting conditions corresponding to changes in the rope related information are set in advance. That is, the knitting condition determining unit 21 of this example is configured to refer to the rope related information and select a knitting condition corresponding to the rope related information from a plurality of knitting conditions.

[Knitting program creation section]
Based on the knitting information input by the user, the knitting program creating unit 29 creates a knitting program in which an actual knitting needle operation, a knitting yarn feeding procedure, and the like are set. The knitting program created by the knitting program creating unit 29 is sent to the flat knitting machine via a recording medium such as a magnetic disk, wired or wireless.

≪Memory≫
The memory 30 is a storage medium such as a hard disk that stores the knitting information (including the rope related information) input by the user and the knitting conditions referred to by the knitting condition determining unit 21. Of course, the memory 30 can store other information related to the design of the knitted fabric, for example, a knitting code assigned to the knitting unit by the user.

≪Display section≫
The display unit 40 is for visually grasping information related to the design of the knitted fabric, and is not particularly limited. Examples of the display unit 40 include a liquid crystal display. If a touch panel is used as the display unit 40, the display unit 40 can have a part of the role of the input unit 10.

≪Procedure for creating a rope pattern knitting program≫
A procedure for creating a knitting program by the knitted fabric design system 100 having the above configuration will be described. First, a user arranges a knitting code on a pattern made of a plurality of knitting units via the input unit 10. At this time, when the knitting code related to the knitting of the rope pattern is arranged in the knitting unit of the knitted fabric, the design system 100 of the knitted fabric is based on the position where the knitting code related to the rope pattern is arranged. Create

  First, the automatic processing unit 20 determines whether the number of first knitting cords arranged continuously in the knitting width direction and the number of second knitting codes arranged continuously in the knitting width direction are three or less. If the larger one is 3 or less, the knitting program creation unit 29 of the automatic processing unit 20 replaces the position of the first stitch row 1 and the position of the second stitch row 2 at a time, and the conventional rope pattern knitting. Create an organization program that includes the method.

  If the number of continuous first knitting codes (second knitting codes) is four or more, the knitting condition determining unit 21 of the automatic processing unit 20 refers to the rope handle related information and stores a plurality of pieces stored in the memory 30. The knitting conditions (1) to (5) corresponding to the reference result are determined from the knitting conditions. For example, the knitting condition (1) relating to the one-time movement distance of the first stitch row 1 may be determined based on information on whether or not the knitting yarn is an elastic knitting yarn. Further, the knitting conditions (2) to (5) described above may be determined based on information on whether or not the knitting yarn is an elastic knitting yarn and the number of stitches in each of the stitch rows 1 and 2.

  If the knitting conditions (1) to (5) are determined, the knitting program creating unit 29 causes the flat knitting machine to execute a rope knitting method that satisfies the determined knitting conditions (1) to (5). Create
