Description

Technical Field

[0001] The present invention relates to a knitting method of a knitted fabric, a knitting program for causing a flat knitting machine to execute the knitting method of the knitted fabric, and a storage medium storing the knitting program. Background Art

[0002] There is known a knitting method of a knitted fabric as follows: using a flat knitting machine having a first needle bed and a second needle bed facing each other, internal decreases (Japanese: 内減らし) and end joining are performed in the middle of knitting a first knitted fabric part and a second knitted fabric part that are connected in a tubular shape by the first needle bed and the second needle bed, respectively. For example, in Patent Document 1, in order to make the shoulder line of a set-in type knitted sweater conform to the shape of the human body, internal decreases for reducing the knitting width of the back body piece and end joining for joining the end loops of the back body piece and the end loops of the front body piece are performed.

[0003] Based on Figure 6 The steps of performing internal decreases and end joining are described. Figure 6 The “S + number” in the left column represents the number of the knitting process. The knitting state in each knitting process is shown in the right column. The black dots in the right column represent the knitting needles provided in the flat knitting machine. The capital letters written below or above the black dots represent the positions of the knitting needles. The long and narrow quadrilaterals shown between the black dots represent sinkers. In the figure, FB represents the front needle bed and BB represents the back needle bed. FB and BB are configured to be able to move relatively horizontally. In this specification, the position of BB relative to FB shown in step S1 is referred to as the reference position.

[0004] In step S1, a state where the first knitted fabric part 1 is fixed to BB and the second knitted fabric part 2 is fixed to FB is shown. The first knitted fabric part 1 is the back body piece and the second knitted fabric part 2 is the front body piece. A part of the right shoulder of the knitted sweater is shown in step S1. The part corresponding to the left shoulder of the knitted sweater is omitted. In subsequent knitting, internal decreases of the first knitted fabric part 1 and end joining of the first knitted fabric part 1 and the second knitted fabric part 2 are performed. In the internal decreases, the first intermediate loops 15, 16 and the second intermediate loops 17, 18 located in the middle part of the knitting width range of the first knitted fabric part 1 are overlapped to reduce the knitting width of the first knitted fabric part 1. In the end joining, the first end loop 10 of the first knitted fabric part 1 is joined to the second end loop 20 of the second knitted fabric part 2.

[0005] In step S2, as a decrease in needle position, a loop train consisting of a series of loops from the first end loop 10 to the first intermediate loop 16, fixed to BB, is moved to FB. In step S3, after BB is moved laterally four intervals to the left, the loop train moved in step S2 is moved to BB. As a result, an overlapping loop 31 is formed on the knitting needle M of BB, where the first intermediate loop 15 and the second intermediate loop 17 overlap, and an overlapping loop 32 is formed on the knitting needle O of BB, where the first intermediate loop 16 and the second intermediate loop 18 overlap.

[0006] In step S4, BB is shifted laterally to the right by one spacing, causing the second end loop 20 of FB to move toward BB. As a result, an overlapping loop 30 is formed on the knitting needle G of BB, where the first end loop 10 and the second end loop 20 overlap. Through this step S4, the knitting yarn 3, which connects the second end loop 20 to the loop of the knitting needle F fixed to FB in step S3, becomes a transition yarn spanning FB and BB. Therefore, the knitting yarn 3, which connects the second end loop 20 to the loop of the knitting needle F fixed to FB, is stretched compared to the state in step S3. In addition, the transition yarn connecting the end loop of the first knitted section 1 to the end loop of the second knitted section 2 in the shoulder line of the left shoulder (not shown) is stretched longer than the knitting yarn 3 because BB is shifted laterally to the left by three spacings from the standard position.

[0007] In step S5, BB is returned to the reference position, and at least one loop row is woven from the loop column 4 constituting the first knitted section 1. If a continuous loop column 4 is woven in the wale direction of the overlapping loops 30, 31, and 32, the overlapping loops 30, 31, and 32 are fixed. Here, BB is returned to the reference position when weaving a new loop row because if a new loop row of the first knitted section 1 is woven while the transition yarn across FB and BB is stretched too long, a large load will be applied to the transition yarn, which may cause the transition yarn to break. In particular, the transition yarn in the shoulder line of the left shoulder (not shown) is stretched longer than the knitted yarn 3 shown, and is therefore prone to breakage.

[0008] Following step S5, an inner decrease and end joining are also performed at the left shoulder position (not shown). The inner decrease and end joining at the left shoulder position are performed through a process symmetrical to the steps shown in steps S2 to S5. In step S6, the state of the loop at the right shoulder position is shown when the processes corresponding to steps S2 and S3 are performed at the left shoulder position (not shown). The knitting yarn 3 in the shoulder line of the right shoulder becomes the length that connects two loops spaced four intervals apart in the knitting width direction.

[0011] Patent Document 1: International Publication No. 2000 / 012799

[0012] For reference Figure 6 As explained, in conventional weaving processes, the transition yarn spanning FB and BB is often stretched to a considerable length. Depending on the type of weaving yarn, the weaving yarn may break when the transition yarn is stretched. For example, in step S6, the weaving yarn 3 is prone to breakage when stretched in the weaving width direction by an amount corresponding to the four spacings. Summary of the Invention

[0016] <1> The knitting method of the present invention uses a flat knitting machine having a first needle bed and a second needle bed facing each other. In the middle of a first knitted section and a second knitted section, which are respectively knitted by the first needle bed and the second needle bed into a tubular connected shape, an inner decrease and an end joining are performed. In the inner decrease, a first intermediate loop of the first knitted section overlaps with a second intermediate loop. In the end joining, a first end loop of the first knitted section is joined with a second end loop of the second knitted section. The end joining includes a step A in which the first end loop and the second end loop are moved towards a position close to the center in the knitting width direction; a step B in which the first end loop overlaps with the second end loop after step A; and a step C in which a new loop column is continuously knitted in the wale direction of the loop column containing the overlapping loop formed in step B.

[0057] Hereinafter, weaving methods, weaving procedures, and storage media of the woven fabric according to embodiments will be described based on the accompanying drawings.

[0058] <Implementation Method 1>

[0059] Knitted Fabrics

[0060] First, based on Figure 1The knitted fabric 5 in this embodiment is described. The knitted fabric 5 in this embodiment is a sweater. The sweater has a front panel 5F and a back panel 5B connected in a tubular shape. The right sleeve 5R and left sleeve 5L of the sweater are of the inset type. The sweater is knitted from the hem. Specifically, the front panel 5F and back panel 5B are knitted from the hem to the armpit, and the right sleeve 5R and left sleeve 5L are knitted independently of the panels 5F and 5B. At the armpit, the panels 5F and 5B are joined to the sleeves 5R and 5L, and knitting continues until the neckline. Finally, the collar 5C is knitted continuously in the warp direction of the neckline loops.

[0061] The knitted sweater is knitted using a flat knitting machine. In this example, the knitting method of the present invention is implemented when forming the shoulder seams of the knitted sweater. Here, the knitted fabric woven by the knitting method of the present invention is not limited to knitted sweaters; for example, it can also be knitted items such as shorts or skirts, or industrial products such as seat covers.

[0062] Horizontal Knitting Machine

[0063] Figure 2 This is a schematic diagram illustrating an example of a flat knitting machine 9. The flat knitting machine 9 is a two-bed flat knitting machine equipped with a pair of needle beds 9B arranged facing each other in the paper depth direction. The pair of needle beds 9B are also referred to as the front needle bed (FB) and the rear needle bed (BB). Multiple knitting needles are arranged side-by-side on the needle beds 9B, driven by a cam system mounted on a carriage 9C that reciprocates on the needle beds 9B. The knitting needles can be latch needles with a tongue that opens and closes a hook, or composite needles with a slider that opens and closes a hook. The flat knitting machine 9 also includes a yarn feeder 9F that supplies knitting yarn 9Y to a toothed opening formed between the pair of needle beds 9B. The yarn feeder 9F travels along a track 9R. The track 9R extends above the needle beds FB and BB, parallel to the needle beds FB and BB. The knitting yarn 9Y is supplied from a top spring device 9T to the yarn feeder 9F via a side tensioning device (not shown).

[0064] The flat knitting machine 9 also has a computer 90 for controlling the flat knitting machine 9. The control of the flat knitting machine 9 includes controlling the movement of the carriage 9C, the operation of the cam system mounted on the carriage 9C, and the movement of the yarn feeder 9F.

[0065] Computer 90 includes processor 91 and storage medium 92. Processor 91 is a variety of processors suitable for controlling computer 90. Processor 91 is, for example, CPU (Central Processing Unit), GPU (Graphics Processing Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), etc.

[0066] Storage medium 92 stores a knitting program for causing the flat knitting machine 9 to knit the fabric. In this example, the knitting program contains instructions for causing the flat knitting machine 9 to perform the knitting method described later. The processor 91, by executing the instructions of the knitting program, causes the flat knitting machine 9 to perform the knitting operation.

[0067] Unlike this example, the computer that controls the flat knitting machine 9 based on the knitting program in this example can also be another computer connected to the flat knitting machine 9 via a network such as LAN (Local Area Network), WAN (Wide Area Network), or the Internet.

[0068] Methods for weaving fabrics

[0069] based on Figures 3 to 5 The knitting process diagram illustrates the specific sequence of knitting methods for fabrics knitted using the aforementioned flat knitting machine 9. The viewpoint on the knitting process diagram differs from that of existing technology. Figure 6 The same applies. In this example, the flat knitting machine 9 is an unequal-pitch flat knitting machine with two knitting needles and a sinker alternately arranged along the length directions of FB and BB. This flat knitting machine 9 is suitable for knitting fabrics with dense loops. When knitting fine yarns, dense loops may cause the yarn to break. Figures 3 to 5 In the weaving method shown, even when fine yarns are woven into dense loops using a flat knitting machine 9, the yarns are not easily broken.

[0070] exist Figure 3 Step S1 shows the state where the first knitted section 1 is secured to BB and the second knitted section 2 is secured to FB. That is, in this example, BB is the first needle bed and FB is the second needle bed. The first knitted section 1 is the back piece 5B ( Figure 1 The second woven part 2 is the front piece 5F ( Figure 1Step S1 shows a portion of the right shoulder of the knitted sweater. The portion corresponding to the left shoulder of the knitted sweater is omitted. In subsequent knitting, inner decreases of the first knitted section 1 and end joining of the first knitted section 1 and the second knitted section 2 are performed. In the inner decreases, the first intermediate loops 15 and 16, located in the middle of the knitting width range of the first knitted section 1, are overlapped with the second intermediate loops 17 and 18 to reduce the knitting width of the first knitted section 1. In the end joining, the first end loop 10 of the first knitted section 1 is joined with the second end loop 20 of the second knitted section 2.

[0071] In step S2, the loops of the first knitted section 1, which are locked to the knitting needles C, E, G, I, K at BB, are moved toward the knitting needles C, E, G, I, K at FB (part of step A and part of step X). The series of loops that are moved includes the first end loop 10 and the first intermediate loops 15, 16.

[0072] In step S3, after shifting BB two distances to the left, the first end loop 10 of the knitting needle C, which is locked to FB, is moved toward the knitting needle E of BB, and the second end loop 20 of the knitting needle D, which is locked to FB, is moved toward the knitting needle F of BB (part of step A). ​​Through this movement, the first end loop 10 moves to a position closer to the center of the knitting width direction than the locking position in step S1, that is, closer to the center of the width direction of the first knitted portion 1 than the knitting needle C of BB. In step S3, the loops of the knitting needles E and G, which are locked to FB, are further moved toward the knitting needles G and I of BB (part of step X).

[0073] In step S4, after shifting BB laterally by a distance to the right, the second end loop 20 of the knitting needle F, which is locked to BB, is moved toward the knitting needle E of FB (part of step A). ​​This movement moves the second end loop 20 closer to the center of the knitting width direction than the locking position in step S1, i.e., closer to the center of the knitting width direction of the second knitted section 2 than the knitting needle D of FB. Furthermore, in step S4, the first intermediate loops 15 and 16 of the knitting needles I and K, which are locked to FB, are moved toward the knitting needles J and L of BB (part of step X). This movement moves the first intermediate loops 15 and 16 closer to the second intermediate loops 17 and 18 than the locking position in step S1.

[0074] exist Figure 4 In step S5, after BB is moved two intervals to the right, the first intermediate loops 15 and 16 of the knitting needles J and L, which are fixed to BB, are moved to the knitting needles K and M of FB (part of step X).

[0075] In step S6, after BB is moved laterally two spacings to the left, the first intermediate loops 15 and 16 of the knitting needles K and M, which are locked to FB, are moved toward the knitting needles L and N of BB (the remainder of step X). Through this movement, the first intermediate loops 15 and 16 are further moved closer to the second intermediate loops 17 and 18.

[0076] In step S7, after BB returns to its reference position by shifting it laterally one distance to the right, continuous loops are knitted in the warp direction of the loops on the knitting needles G, I, L, and N fixed to BB. The newly knitted loops on knitting needles L and N of BB are considered as the first intermediate loops 15 and 16. This step S7 is knitting to facilitate the movement of loops in subsequent processes. Step S7 is not a necessary step and can be omitted.

[0077] In step S8, after BB is moved laterally to the left by a distance, the first intermediate loops 15 and 16 of the knitting needles L and N fixed to BB are moved toward the knitting needles K and M of FB (part of step Y).

[0078] exist Figure 5 In step S9, after shifting BB laterally by a distance to the right, the loops of the knitting needles G and I fixed to BB are moved toward the knitting needles G and I of FB. This movement is used to reduce the distance between the knitting needles. Figure 4 Steps S5 and S6, which extend the first intermediate coil 15 and the spacing between it and the coil to its left, are part of the process and are not mandatory.

[0079] In step S10, after BB is moved laterally to the left by one distance, the first end loop 10 of the knitting needle E fixed to BB is moved toward the knitting needle D of FB (part of step B). In step S11, after BB is moved laterally to the left by two distances, the first end loop 10 of step S10 is moved toward the knitting needle G of BB (part of step B).

[0080] In step S12, after shifting BB laterally by a distance to the right, the second end coil 20 of the knitting needle E, which is fixed to FB, is moved toward the knitting needle G of BB. The coils of the knitting needles G and I, which are fixed to FB, are moved toward the knitting needles I and K of BB. The first intermediate coils 15 and 16 of the knitting needles K and M, which are fixed to FB, are moved toward the knitting needles M and O of BB. Through the movement of the second end coil 20, an overlapping coil 30 (the remainder of step B) is formed on the knitting needle G of BB, which serves as the first needle bed, where the first end coil 10 and the second end coil 20 overlap. Additionally, through the movement of the first intermediate coils 15 and 16, overlapping coils 31 and 32 (the remainder of step Y) are formed on the knitting needles M and O of BB, where the first intermediate coils 15 and 16 overlap with the second intermediate coils 17 and 18. Furthermore, the first end coil 10 and the second end coil 20 can also overlap on FB, which serves as the second needle bed.

[0081] In step S13, a new coil row 4 is continuously woven in the longitudinal direction of the coil row containing overlapping coils 30, 31, and 32 (step C). The coil row 4 constitutes part of the first woven fabric section 1.

[0082] Following step S13, an inner decrease and end join are performed at the left shoulder location (not shown). The inner decrease and end join at the left shoulder location are achieved through... Figure 3 Step S2 to Figure 5 Step S13 is performed symmetrically to the left and right sides. In step S14, it is shown that an operation equivalent to [the operation performed at the left shoulder position, not shown] is performed. Figure 3 The state of the coil at the right shoulder position during steps S2 and S3.

[0083] As explained above, the maximum lateral movement distance in the inner decrease and end joining of the embodiment is only 3. Therefore, yarn breakage is less likely to occur in each process of inner decrease and end joining. The reason why the lateral movement distance can be smaller than before is that, after moving the first end loop 10 and the second end loop 20 to a position closer to the center of the knitting width direction of the fabric than the initial locking position in the end joining, the first end loop 10 overlaps with the second end loop 20. In addition, after gradually moving the first intermediate loops 15 and 16 closer to the second intermediate loops 17 and 18 in the inner decrease, the first intermediate loops 15 and 16 overlap with the second intermediate loops 17 and 18, which also helps to make the lateral movement distance smaller than before.

[0084] <Other Implementation Methods>

[0085] The flat knitting machine 9 used in the knitting method of the present invention can also be a flat knitting machine with equally spaced knitting needles and sinkers arranged alternately. Furthermore, the flat knitting machine 9 used in the knitting method of the present invention is not limited to a two-needle bed flat knitting machine, but can also be a four-needle bed flat knitting machine.

[0086] In Embodiment 1, an inner decrease pin is implemented that overlaps a plurality of first intermediate coils 15, 16 with a plurality of second intermediate coils 17, 18. Alternatively, an inner decrease pin can be implemented that overlaps a single first intermediate coil with a single second intermediate coil. In this case, even without implementing the step X of gradually bringing the first intermediate coil closer to the second intermediate coil, the lateral movement distance between the inner decrease pin and each step in the end engagement is less likely to increase.
