[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-112735 Summary of the Invention
[0006] [The problem the invention aims to solve]
[0007] If the loops constituting the base layer are dense, meaning the loops in the base layer are small and the spacing between adjacent loops is narrow, the quality of the knitted fabric is improved. Furthermore, even in parts of the knitted fabric other than the base layer, if the loops constituting those parts are dense, the quality of the knitted fabric may also be improved. Therefore, there is a need to form loops that are denser than the minimum loop size required for the hardware structure of the flat knitting machine used to knit the fabric.
[0008] In view of the above, one object of the present invention is to provide a knitting method for making the loops of any loop array denser than during knitting. Another object of the present invention is to provide a knitting program for enabling a flat knitting machine to perform the knitting method for the above-mentioned knitted fabric and a storage medium storing the knitting program.
[0009] [Methods used to solve problems]
[0010] <1> The present invention discloses a method for knitting fabric using a flat knitting machine. The flat knitting machine includes a plurality of needle beds facing each other, a yarn feeder for supplying knitting yarn between the plurality of needle beds, and a movable clamp for holding the knitting yarn. The movable clamp is configured to move along the length of the plurality of needle beds. The knitting method of the knitted fabric includes: Step A: Using the yarn feeder, weave a first loop column that is part of the knitted fabric; Step B, before or after step A, involves holding the knitted yarn extending from the first loop column to the outside of the knitting range of the first loop column by the movable clamp; and Step C, after steps A and B, forms a state in which tension is applied from the movable clamp to the knitting yarn connected to the first coil column.
[0011] Methods for applying tension to the knitting yarn connected to the first loop train from a movable clamp include, for example, moving the movable clamp, knitting the fabric while the knitting yarn is held by the movable clamp, or moving the needle bed laterally while the knitting yarn is held by the movable clamp. In the latter method, the first loop train is fed downwards towards the teeth by knitting the fabric. If the first loop train descends downwards towards the teeth while the knitting yarn is held by the movable clamp, tension is applied to the knitting yarn extending from the first loop train towards the movable clamp by the weight of the fabric and the pulling of the fabric's pull-down device. That is, the same effect as pulling the knitting yarn by moving the movable clamp can be obtained.
[0012] <2> Alternatively, it could be in the above... <1> In step C of the described knitting method, tension is applied to the knitting yarn by moving the movable clamp to pull it.
[0013] <3> Alternatively, it could be in the above... <1> or <2> In step C of the described knitting method, when step C is performed, the movable clamp is moved in such a way that it passes through any one of the multiple loops hooked on the needle bed, i.e., a specific loop, and after the movable clamp passes through the specific loop, the specific loop is moved toward the opposite needle bed, thereby winding the knitting yarn around the specific loop.
[0014] Here, the relative needle bed in process C refers to the needle bed opposite to the needle bed with the specific loop hooked before the yarn feeder crosses the specific loop.
[0015] <4> The knitting program of the present invention is a knitting program that can be read by a computer controlling a flat knitting machine. The flat knitting machine includes a plurality of needle beds facing each other, a yarn feeder for supplying knitting yarn between the plurality of needle beds, and a movable clamp for holding the knitting yarn. The movable clamp is configured to move along the length of the plurality of needle beds. The knitting program of the present invention enables the flat knitting machine to perform the knitting method for the fabric described in any one of <1> to <3> above.
[0016] <5> The storage medium of the present invention is a storage medium that stores the weaving program described in <4> above.
[0017] [Invention Effects]
[0018] In the knitting method of the present invention, after knitting the first loop, tension is applied to the knitting yarn extending from the first loop towards the movable clamp. The first loop may consist of a single loop or multiple loops. By setting the state of applying tension to the knitting yarn extending from the first loop after knitting the first loop, at least one loop constituting the first loop can be made denser than when it is formed during knitting, i.e., by unwinding old loops. With this knitting method, by increasing the tension of the knitting yarn, it is also possible to form a loop that is denser than the smallest loop corresponding to the hardware structure of a flat knitting machine as described later.
[0019] In the knitting method of <2> described above, the knitting yarn extending from the first loop column to the movable clamp is pulled by moving the movable clamp. Therefore, the tension acting on the knitting yarn can be easily adjusted by changing the moving speed and moving distance of the movable clamp.
[0020] In the knitting method described in <3> above, the knitting yarn held by a movable clamp is wound onto a specific loop. During the winding of the knitting yarn onto the specific loop, the knitting yarn extending from the first loop column is pulled, thus making the loops of the first loop column denser than during knitting. Furthermore, since the knitting yarn is fixed by being wound onto the specific loop, it is easy to maintain the dense state of the first loop column. Moreover, when the knitting yarn held by the movable clamp is an end yarn with a cut end, the end yarn is fixed by being wound onto the specific loop, making it difficult for the end yarn wrapped around the knitted fabric to detach from the knitted fabric.
[0021] According to the knitting program of the present invention, a flat knitting machine can implement the knitting method of the present invention for knitted fabrics. The computer executing the knitting program can be located on the flat knitting machine or connected to the flat knitting machine via wired or wireless means.
[0022] A flat knitting machine can implement the knitting method of the present invention by means of a storage medium storing the knitting program of the present invention. The storage medium can be equipped with the flat knitting machine when the knitting program is executed, or it can be connected to the flat knitting machine via wired or wireless means. The storage medium can also be a portable storage medium such as a USB memory. Attached Figure Description

[0044] <Implementation Method 1>
[0045] Knitted fabrics
[0046] Figure 1The knitted fabric 5 of Embodiment 1 shown is a finger cot for a glove. A starting base 50 is formed at the fingertip portion of the finger cot, and the portion continuing from the starting base 50 is branched back and forth before the finger cot is knitted into a tubular shape. That is, the finger cot is knitted starting from the fingertip. The finger cot is knitted into a tubular shape using a flat knitting machine. The tubular knitted fabric 5 has a front knitted fabric portion 5F and a back knitted fabric portion 5B. Here, the knitted fabric 5 knitted by the knitting method of the present invention is not limited to finger cots, and can also be other tubular knitted fabrics. Other tubular knitted fabrics can be, for example, knitted items such as shorts or skirts, or industrial materials such as seat covers. The knitted fabric 5 is not limited to tubular knitted fabrics, and can also be a single-layer knitted fabric.
[0047] The end yarn 9 extends from the beginning of the bottom 50. That is, in this example, the end yarn 9 is the end yarn 9 of the yarn entry section. A cut end 90 is formed at the end of the end yarn 9. The end yarn 9 is stored in the knitted fabric 5 and is not conspicuous. The end yarn 9 is processed, for example, by manual operation.
[0048] In this example, the flat knitting machine performs a process that makes the loops constituting the bottom 50 of the loop column dense after the loop column is knitted. Hereinafter, the structure of the flat knitting machine will be described first, followed by the knitting method of the knitted fabric of the present invention.
[0049] Flat knitting machine
[0050] Figure 2 This is a schematic diagram illustrating an example of a flat knitting machine 6 used to knit the aforementioned fabric 5. The flat knitting machine 6 is a two-bed flat knitting machine equipped with a pair of needle beds 6B arranged opposite each other in the depth direction of the paper. The pair of needle beds 6B are also referred to as the front needle bed (hereinafter referred to as FB) and the back needle bed (hereinafter referred to as BB), respectively. The flat knitting machine 6 is equipped with a transverse movement mechanism 65 that offsets the relative positions of FB and BB along the length of FB and BB. The transverse movement mechanism 65 can utilize a known structure. The flat knitting machine 6 used to knit the fabric 5 can also be a four-bed flat knitting machine equipped with a lower front needle bed, a lower back needle bed, an upper front needle bed, and an upper back needle bed.
[0051] Multiple knitting needles are arranged side-by-side on the needle bed 6B. These needles are driven by a cam system mounted on a cam carriage 6C that reciprocates on the needle bed 6B. The cam system includes a loop transfer mechanism 66, i.e., a loop transfer cam, that moves the loop between FB and BB. The knitting needles can be latch needles with opening and closing hooks, or composite needles with opening and closing hooks. The flat knitting machine 6 also includes multiple yarn feeders 6F that supply knitting yarn 6Y to a toothed opening formed between a pair of needle beds 6B. Each yarn feeder 6F is mounted on any one of multiple tracks 6R and travels along the tracks 6R. The multiple tracks 6R extend above the needle beds 6B and parallel to the needle beds 6B. The knitting yarn 6Y is supplied from the antenna assembly 6T to the yarn feeders 6F via a side tensioning device (not shown).
[0052] Here, in the hardware structure of the flat knitting machine 6, for example, during the weaving of the next two patterns, it is possible to form the smallest possible coil. First, when the bottom 50 is woven by forming loops in a zigzag pattern at FB and BB, the coil of the bottom 50 becomes the smallest possible coil. Second, when the size of the coil is determined using the cam system provided by the cam carriage 6C, the smallest possible coil is also formed even when the stitch value is woven at zero.
[0053] The flat knitting machine 6 in this example includes a movable clamp 6G for holding the knitting yarn. The movable clamp 6G is configured to move along the length of the needle bed 6B. Therefore, the movable clamp 6G can move along the direction of the needle bed 6B while holding the knitting yarn. The movable clamp 6G can be a known movable clamp, such as the movable clamp described in International Publication No. 2009 / 084193. Alternatively, a cutter (not shown) for cutting the knitting yarn 6Y can be integrated with the movable clamp 6G.
[0054] The flat knitting machine 6 is equipped with a computer 60 for controlling the flat knitting machine 6. The control of the flat knitting machine 6 includes controlling the movement of the triangular carriage 6C, the movement of the triangular system mounted on the triangular carriage 6C, and the movement of the yarn feeder 6F.
[0055] Computer 60 includes processor 61 and storage medium 62. Processor 61 is any processor suitable for controlling computer 60. Processor 61 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.
[0056] Storage medium 62 stores a knitting program for causing the flat knitting machine 6 to knit the fabric 5. In this example, the knitting program contains instructions for causing the flat knitting machine 6 to perform the knitting method described later. The processor 61, described above, causes the flat knitting machine 6 to perform the knitting operation by executing the instructions of the knitting program.
[0057] Unlike this example, the computer that controls the knitting machine 6 based on the knitting program in this example can also be another computer connected to the knitting machine 6 via a network such as LAN (Local Area Network), WAN (Wide Area Network), or the Internet.
[0058] [Knitting Methods for Fabrics]
[0059] based on Figure 3 The knitting process diagram illustrates the specific knitting method of the fabric 5 using the aforementioned flat knitting machine 6. The "S + number" surrounded by four corners in the diagram indicates the knitting process number, the black dots represent the needles on the needle bed 6B, and the inverted triangle mark represents the yarn feeder 6F.
[0060] In step S1, the movable clamp 6G holds the device from the flat knitting machine 6 ( Figure 2 The side tension device extends the knitting yarn 6Y (equivalent to step B) to the yarn feeder 6F. This knitting yarn 6Y is the end yarn 9 of the yarn inlet. The end yarn 9 has a cut end 90.
[0061] In step S2, the yarn feeder 6F is moved to weave the first loop column 1 forming the bottom 50 (equivalent to step A). In step S2, the yarn feeder 6F is further moved to weave the tubular second loop column 2 continuing in the longitudinal direction of the first loop column 1, and the tubular third loop column 3 continuing in the longitudinal direction of the second loop column 2. The second loop column 2 and the third loop column 3 constitute... Figure 1 The portion of the tubular knitted fabric 5 that continues in the longitudinal direction at the starting point 50. Figure 3 The diagram shows the first coil column 1, the second coil column 2, and the third coil column 3.
[0062] In step S3, the movable clamp 6G is moved to pull the end yarn 9, making at least a portion of the coils 10 constituting the first coil column 1 denser than during weaving (equivalent to step C). The denser state of the coils 10 in the first coil column 1 compared to during weaving means that, compared to the first coil column 1 in step S2, each coil 10 is smaller and the spacing between adjacent coils 10 is smaller. Among the multiple coils 10 constituting the first coil column 1, the coils 10 closer to the end yarn 9 tend to become smaller, while the coils 10 farther from the end yarn 9 are less likely to become smaller.
[0063] In this example, the direction in which the movable clamp 6G moves, as indicated by the hollow arrow, is away from the first coil row 1. Although it is difficult for the coils 10 constituting the first coil row 1 to be in a slightly denser state, the movable clamp 6G can still be moved in the opposite direction to the hollow arrow to pull the end yarn 9. Unlike this example, the movement of the movable clamp 6G can be performed after the weaving of the second coil row 2 and before the weaving of the third coil row 3, or after the weaving of a coil row (not shown) that follows the third coil row 3.
[0064] According to the knitting method of this example, after the first loop row 1 is detached from the needle bed 6B, the loops 10 constituting the first loop row 1 can be made to be denser than during knitting. According to the knitting method of this example, loops denser than the smallest loops knitted by the hardware structure of the flat knitting machine 6 can be formed. The first loop row 1 in this example constitutes... Figure 1The knitted fabric 5 shown is the starting point 50 of the finger sleeve, so the loops constituting the starting point 50 are in a dense state. As a result, the fixed loops branching from the starting point 50 to the front and back are dense, making it difficult to make holes at the front end of the finger sleeve, thus improving the quality of the finger sleeve.
[0065] <Implementation Method 2>
[0066] In implementation method 2, based on Figure 4 This describes a knitting example in which the loops of the first loop column 1, which are hooked onto the needle bed 6B, are made to be in a dense state on the needle bed 6B. Figure 4 Observation methods and Figure 3 same.
[0067] exist Figure 4 In step S10, the knitting yarn 6Y, which serves as the end yarn 9, is held by the movable clamp 6G during yarn feeding (equivalent to step B). In step S11, following step S10, the yarn feeder 6F is moved to knit the first loop column 1 (equivalent to step A). In step S12, which follows step S11, before knitting the loop column (not shown) that continues in the longitudinal direction of the first loop column 1, the movable clamp 6G is moved to pull the end yarn 9, thereby making the loops 10 constituting the first loop column 1 denser than during knitting (step C).
[0068] According to the knitting method of this example, compared with the knitting of the first loop row 1, the loops 10 constituting the first loop row 1 can be made denser. Therefore, a dense knitted fabric 5 can be knitted.
[0069] <Implementation Method 3>
[0070] In implementation method 3, based on Figure 5 This describes a knitting example in which the loops of the first loop column 1 connected to the yarn exit section are made dense, that is, a knitting example in which the knitting yarn 6Y is held by the movable clamp 6G after the first loop column 1 is knitted. Figure 5 Observation methods and Figure 3 same.
[0071] exist Figure 5 In step S20, the yarn feeder 6F is moved to weave the first loop column 1 (step A). In step S21 following step S20, the movable clamp 6G holds the knitting yarn 6Y extending from the last loop 10 woven in the first loop column 1 toward the yarn feeder 6F (step B). In step S22 following step S21, before weaving the loop column (not shown) that continues in the longitudinal direction of the first loop column 1, the movable clamp 6G is moved to pull the end yarn 9, thereby making the loop 10 constituting the first loop column 1 denser than during weaving (step C).
[0072] According to the knitting method of this example, compared with the knitting of the first loop row 1, the loops 10 constituting the first loop row 1 can also be made dense. Therefore, it is possible to knit a dense knitted fabric 5.
[0073] <Implementation Method 4>
[0074] In implementation method 4, based on Figure 6 The weaving process diagram illustrates a weaving example where the movable clamp 6G operates differently from embodiments 1 to 3. Figure 6 In the center, FB and BB are indicated by thick lines. The uppercase letters outside the top column indicate the position of the knitting needles. "T + number" in the left column indicates the knitting sequence number. Straight arrows indicate the direction of loop movement or the direction of movement of the movable clamp 6G.
[0075] In embodiment 4, after weaving the fabric of embodiment 1... Figure 3 Following the first coil row 1 shown, a cylindrical second coil row 2, which continues from the first coil row 1, is woven. Figure 6 In step T1, it indicates the end of weaving the second coil column 2. From the first coil column 1 ( Figure 3 The extended end yarn 9 is held by the movable clamp 6G.
[0076] In steps T2 to T5, the end yarn 9 is wound onto the specific loop 4 hooked onto the needle E of BB (equivalent to step C). In this example, the specific loop 4 is the loop hooked onto the second loop column 2 of BB at step T1. Unlike this example, the specific loop 4 could also be another loop column continuing in the longitudinal direction of the second loop column 2, for example… Figure 3 The coil of the third coil column 3 shown.
[0077] In step T2, the specific loop 4 hooked on needle E of BB is moved towards needle F of FB. In step T3, the movable clamp 6G is moved to the left so that it passes through the specific loop 4. In step T4, the specific loop 4 is returned to needle E of BB. The end yarn 9 is wrapped around the outside of the specific loop 4. In step T5, the movable clamp 6G is moved to the right so that it passes through the specific loop 4. Through this series of steps, the end yarn 9 is wound on the specific loop 4. In addition, in this series of steps, the end yarn 9 is pulled by the movement of the movable clamp 6G, thus forming the first loop row 1 connected to the end yarn 9. Figure 3 The coils become denser than when they were braided. In this example, the process is repeated again. Figure 6 The weaving from step T2 to step T5.
[0078] based on Figure 7 The coil diagram illustrates the state of end yarn 9 wound around a specific coil 4. Figure 7The image shows only the portion of the BB knit in fabric 5. Figure 7 The dashed lines in the diagram indicate connections to parts not shown in the illustration. End yarn 9 is represented by a thick line. The portion of end yarn 9 opposite to the cut end 90 connects to the first loop column 1. (See figure) Figure 7 As shown, at the end of step T5, the end yarn 9 is wound around the specific coil 4 in a manner that surrounds the specific coil 4.
[0079] In this example, after step T5 in the second step, the third coil 3 is woven in the longitudinal direction of the second coil column 2, and then the weaving process from step T2 to step T5 is repeated again. The result is as follows: Figure 7 As shown, the end yarn 9 is wound onto a specific loop 4 of the third loop 3, which continues in the longitudinal direction of the second loop column 2. By winding the end yarn 9 onto the two specific loops 4, the end yarn 9 is difficult to fall off from the knitted fabric 5. The more times the end yarn 9 is wound onto the specific loops 4, the more knitting steps are required, but the fixation of the end yarn 9 to the knitted fabric 5 becomes stronger. As a result, the end yarn 9 is difficult to fall off from the knitted fabric 5. The number of windings is not limited, but is preferably around 2 to 3 times. Of course, the number of windings can also be 1 time.
