Description

Flat knitting machine and knitting method for pile knitting

The present invention relates to a flat knitting machine for pile knitting for knitting a pile knitted fabric in a cylindrical shape, and a knitting method therefor.

Conventionally, a flat knitting machine having a pair of needle beds opposed to each other with a needle bed gap therebetween can knit a cylindrical pile knitted fabric. (For example, refer patent document 1). The pile knitted fabric is knitted using two types of knitting yarns, a blank yarn and a pile yarn, and a ring made of a pile thread is formed on the surface of the knitted fabric made of the blank yarn. It has a raised tissue. Since the blank thread functions to tighten the ring of the pile thread, it is also called a fastening thread. A knitting needle for knitting a pile knitted fabric is a latch needle that opens and closes a hook by a latch, and a hook for knitting yarn coupling is formed at an inner edge of the latch. The pile knitting is performed using this knitting needle and a movable sinker for pile knitting that advances and retreats to the needle bed gap. The pile knitting sinker has a pile pawl and a blank yarn pawl through which a sinker loop of a pile yarn and a blank yarn is applied during stitch formation, respectively. In pile knitting by a flat knitting machine, a ring is formed by making the sinker loop of the pile yarn larger than the sinker loop of the blank yarn at the time of stitch formation.

When knitting a knitted fabric in a cylindrical shape by a flat knitting machine, an end stitch, which is a stitch near the longitudinal end of the knitted fabric connected by the knitting yarn with a needle bed gap therebetween, is contracted. becomes smaller, and the stitches are widened at the boundary portion passing through the needle bed gap, which may cause a problem of impairing the aesthetics of the appearance (see, for example, Patent Document 2). As a countermeasure for this problem, in the invention described in Patent Document 2, when the end stitch is formed, the diameter expansion member is penetrated into the knock-over old stitch, and the stitch is formed. to restore its size.

: Japanese Patent Publication No. 60-59333 : Japanese Patent Laid-Open No. 2010-156085

In the cylindrical pile knitted fabric, not only the change in the stitch size at the boundary portion but also the size of the ring due to the pile yarn becomes smaller at the boundary portion, the aesthetics of the appearance is easily impaired. Even when expanding the contracted old stitch like in Patent Document 2, since the direct action does not reach the sinker loop, it is still insufficient for expanding the sinker loop.

An object of the present invention is to provide a flat knitting machine for pile knitting and a knitting method for preventing the sinker loop of the pile yarn of the end stitch from shrinking when a tubular knitted fabric is knitted by pile knitting.

The present invention is provided with a pair of needle beds opposed to each other with a needle bed gap therebetween, and as a knitting yarn, a blank yarn and a pile yarn, one needle bed in one direction, and the other needle bed in the opposite direction, are uniform as a whole.

characterized.

Further, the present invention provides a flat knitting machine having a pair of needle beds opposed to each other with a needle bed gap interposed therebetween, wherein a blank yarn and a pile yarn as knitting yarns, one needle bed in one direction, and the other needle bed in the opposite direction, are used as knitting yarns. In the pile knitting knitting method of knitting a tubular pile knitted fabric by connecting the knitted fabrics knitted on each needle bed at both ends of a knitting width while rapidly spinning so as to go around in a certain direction as a whole, the pile knitting method comprising:

Adjacent to the upstream side in the feeding direction with respect to the knitting needle that becomes the end of the knitting width in each needle bed and forms the end stitch, a sinker for end stitch having a pole for pile on which the pile thread is caught when forming the end stitch is disposed,

In each needle bed, between the knitting needles disposed adjacent to the upstream side in the feeding direction and the knitting needles serving as the starting end of the knitting width with respect to the knitting needles serving as the end of the knitting width and forming the end stitches, piles during stitch formation A sinker for pile knitting having a pole for pile on which a thread is applied and a pole for a blank thread on which the blank thread is applied at the tip moving forward and backward to the needle bed gap is arranged,

In accordance with the stitch formation in each knitting needle, the tip portions of the sinker for pile knitting and the sinker for end stitching enter the needle bed gap, and the tip of the sinker for pile knitting after stitch formation exits the needle bed gap, and the sinker for end stitching is a pile A sinker loop is formed on the pole for use by pile thread, and after the sinker loop is formed, the tip is stopped at the needle bed gap to maintain the state of joining the sinker loop until just before the knitting yarn for forming the end stitch is received in the next course. to do

It is a method of organizing the file organization characterized by it.

According to the present invention, when the end stitch is formed, the sinker loop of the pile yarn formed on the pile pole of the sinker for the end stitch receives the feeding yarn of the knitting yarn for forming the end stitch in the next course under the control of the sinker control means. Until just before, it is joined by a pole for a file. By combining, the sinker loop of the pile yarn of the end stitch is maintained at a length similar to that at the time of formation, thereby preventing shrinkage.

In addition, according to the present invention, since the sinker for the end stitch does not have a portion to which the base thread hangs when forming the end stitch, the sinker loop of the base thread formed at the time of forming the end stitch becomes shorter. It becomes difficult for the base yarn to be drawn from the end stitch to the knitted fabric that is started knitting on the opposite needle beds, and the pile yarn is also difficult to be drawn in along with the base yarn, and the ring by the sinker loop of the pile yarn is also difficult to be reduced.

In addition, according to the present invention, the angle with respect to the vertical downward direction of the inclination formed on the edge of the pile pole is larger than the angle with respect to the vertical downward direction in the direction in which the end stitch sinker enters obliquely downward of the needle bed gap. . The sinker loop of the pile seal becomes difficult to separate from the pile pawl after it is formed at the edge, so that the joint state can be stably maintained.

Further, according to the present invention, the sinker for end stitching and the sinker for pile knitting are driven by a common cam, and the control can be differentiated by the difference in the protrusion amount of the butt.

In addition, according to the present invention, the sinker loop of the pile yarn formed on the pile pole of the sinker for the end stitch at the time of forming the end stitch is applied to the pile pole until just before receiving the feeding yarn for the knitting yarn for forming the end stitch in the next course. Since they are joined together by this, it is possible to prevent the sinker loop of the pile thread of the end stitch from being reduced.

Corresponding parts in each drawing are denoted by the same reference numerals, and overlapping explanations may be omitted. In addition, for convenience of explanation, parts not described in the drawings to be described may be referred to with reference numerals described in other drawings.

(Example)

1 and 2 respectively show the operation and configuration of main parts of the flat knitting machine 1 for pile knitting, which is an embodiment of the present invention. A flat knitting machine 1 for pile knitting includes a pair of needle beds 3F and 3B facing each other with a needle bed gap 2 interposed therebetween. However, in Fig. 2, only one needle bed 3F is shown. The needle bed 3B, not shown, is disposed at a position substantially symmetrical to the needle bed 3F with respect to the virtual center plane 2a of the needle bed gap 2 . Needle beds (3F, 3B) is a substrate (基板) extending in the knitting width direction perpendicular to the paper surface (紙面) of Figs. 1 and 2, needle plate (needle plate) 5 is parallel is formed A needle groove (6) is formed between the needle plates (5), and a knitting needle (7) is accommodated. The knitting needle 7 has a hook 7a at the tip end of the needle bed gap 2 side, and also has a latch 7b for opening and closing the hook 7a, and a needle groove ( 6) slides so that the tip advances and retreats to the needle bed gap (2). A band 8 prevents the knitting needle 7 from falling off from the needle groove 6 . Sinker bed attachment plates 9 installed at both ends in the knitting width direction support the sinker bed 10 . The sinker bed 10 is such that the tip ends of the sinker for end stitch 11 and the sinker for pile knitting 12 can advance and retreat into the needle bed gap 2 . Accept.

3 shows a state in which a cylindrical pile knitted fabric 30 is knitted on the needle beds 3F and 3B as will be described later. 1 and 2 correspond to the lateral cross-sectional configuration seen from the cut line I-I in Fig. 3, except for Fig. 2 (d2). 4 shows the shapes of the sinker 11 for end stitching and the sinker 12 for pile knitting, as will be described later. 1, the front end of the sinker 11 for end stitching is shown. A pile pawl 11a is formed at this tip end.

As shown in Fig. 2, the carriage 20 includes a knitting cam 21 and a sinker cam for driving the knitting needle 7, the end stitch sinker 11, and the pile knitting sinker 12. (sinker cam) 22 are mounted respectively. The driving for sliding the knitting needle 7 is a knitting cam 21 that guides a butt 7d protruding from a jack 7c connected to the tail end of the knitting needle 7 toward the carriage 20 side. ) is done by A blank yarn 31 and a pile yarn 32 for pile knitting are supplied from yarn feeders 33 and 34, respectively. The carriage 20 can reciprocate in the knitting width direction, and the yarn feeders 33 and 34 can be selectively interlocked.

1 (a), (b), (c), (d) shows the operation of the sinker 11 for end stitching. (a) shows a state in which the tip is withdrawn from the needle bed gap 2 without acting on the knitting yarn. The sinker 11 for the end stitch is from the time of forming the end stitch until just before receiving from the yarn feeders 33 and 34 the feeder for forming a new stitch in the next course after the formation of the end stitch. The sinker loop (38e) shown in is coupled to the pole (11a) for the pile (11a) is continuously maintained in a supported state. The yarn feeders 33 and 34 travel inward from the surface side of the ground. When the yarn feeders 33 and 34 approach, the tip of the sinker 11 for end stitching is withdrawn from the needle bed gap 2 so that a new sinker loop can be formed after releasing the sinker loop 38e. . The needle loop of the stitch supported by the hook 7a opens the latch 7b and moves to the needle interval of the knitting needle 7, but illustration is omitted.

Fig. 1B shows a state in which the formation of a new end stitch is started. By supplying the blank yarn 31 from the yarn feeder 33, while the knitting needle 7 is pulled out from the needle bed gap 2 in a state over the knitting hook formed on the inner edge of the latch 7b, the knitting needle 7 is drawn in. , the tip of the sinker 11 for the end stitch enters the needle bed gap (2). The hook for knitting yarn is described in Patent Document 1. The base thread 31 is pressed so as to pass through the lower side of the bottom of the tip of the sinker 11 for end stitching.

1(c) shows, a new end stitch is formed by drawing in the knitting needle 7, and the hook 7a is hooked with the latch 7b by knock over of the end stitch that becomes the old stitch. ) indicates the closed state. The pile yarn 32 is supplied from the yarn feeder 34 to the hook 7a, and as shown in Fig. 7, the blank yarn 31 by the hook 7a and the needle loop 35e of the pile yarn 32; 36e) and the sinker loop 38e of the pile thread 32 by the pile pole 11a of the sinker 11 for end stitching is formed. The sinker loop 37e of the base room 31 is formed over the tip edge 5a of the needle plate 5 shown in Fig. 2(a) facing the needle bed gap 2 . In the sinker 12 for pile knitting, since the base yarn pole 12c is also formed together with the pile pole 12a, the sinker loop 37 of the base yarn 31 is formed over the base yarn pole 12c. . Since the base yarn pole 12c protrudes toward the needle bed gap 2 side from the tip edge 5a of the needle plate 5, the sinker of the base yarn 31 formed by the pile knitting sinker 12. The loop 37 becomes longer than the sinker loop 37e in the case of using the sinker 11 for end stitching.

Fig. 1(d) shows a state in which the sinker loop 38e by the pile thread 32 of the final stitch is coupled by the sinker 11 for the final stitch even after the stitch size is determined. The sinker cam 22 has an entry edge 22a and an exit edge 22b. The entry edge 22a and exit edge 22b are the tip sides 11d and 12d and the butt of the sinker 11 for end stitching shown in Fig. 4(a) and the sinker 12 for pile knitting shown in (b). They act on the sides 11e and 12e, respectively. 1(a), (b), and (c), the sinker 11 for end stitching and the sinker 12 for pile knitting receive the same drive. Fig. 1 (d) corresponds to Fig. 2 (d1), and the end stitch sinker 11 is driven differently from the pile knitting sinker 12 shown in Fig. 2 (d2). As shown in Fig. 2 (d2), after determining the stitch size in the stitch formation, the pile knitting sinker 12 is driven by the exit edge 22b of the sinker cam 22 so that the tip ends with a needle bed gap ( 2), and the formed sinker loop 38 is released. The sinker cam 22 basically drives the sinker 11 for end stitching and the sinker 12 for pile knitting in common, but has a step portion 22c on the exit edge 22b side. The exit edge 22b serving as the outer periphery of the step portion 22c acts on the butt 12b of the pile knitting sinker 12 to withdraw the tip portion from the needle bed gap 2, and the pile pawl 12a and the sinker loops 38 and 37 of the pile room 32 and the base room 31 are released from the base room pole 12c. The exit edge 22b of the step portion 22c does not act on the butt 11b of the sinker 11 for end stitches with a small protrusion amount. The butt 11b is guided to the supporting edge 22d serving as the inner periphery of the step portion 22c, so that the sinker loop 38e is not released from the pile pawl 11a. The sinker loop 38e of the pile yarn 32 coupled by the sinker 11 for end stitching is released in (a) of the next knitting course.

Fig. 3 shows a configuration for knitting a tubular pile knitted fabric 30 on the needle beds 3F and 3B of the flat knitting machine 1 for pile knitting of Fig. 1 . As a knitting yarn, the base yarn 31 and the pile yarn 32 have one needle bed 3F, for example, a carriage 20 running in one direction from right to left on the front needle bed. The yarn feeders 33 and 34 are fed from the interlocking yarn feeders. In the rear needle bed as the other needle bed 3B, the running direction of the carriage 20 is reversed, and yarn is fed from the left to the right in the reverse direction. In this way, the yarn as a whole is fed rapidly so that it rotates in a constant clockwise direction. The one-course knitted fabrics knitted in each of the needle beds 3F and 3B are basically the same, and are connected at both ends of the knitting width to form a cylindrical pile knitted fabric 30 . The knitting needle 7 is a generic name, and in some cases, symbols F and B are added to the reference numeral 7 depending on the needle beds 3F and 3B to which they belong, and a code corresponding to the position is added in some cases. A pile knitting sinker 12 is basically arranged between the knitting needles 7 . The sinker 11 for the end stitch is disposed adjacent to the upstream side in the feeding direction with respect to the knitting needles 7Fe and 7Be that become the ends of the knitting width in each of the needle beds 3F and 3B and form the end stitch, , has a pole 11a for a pile on which the pile thread 32 is caught when the end stitch is formed. The pile knitting sinker 12 has a knitting width with the knitting needles 7F and 7B disposed adjacent to the upstream side in the feeding direction with respect to the knitting needles 7Fe and 7Be forming the end stitch between the other knitting needles 7, that is, the knitting width. It is arrange|positioned between knitting needles 7F, 7Fs, 7B, 7Bs between knitting needles 7Fs, 7Bs used as the starting end of . The sinker 13 adjacent to the downstream side of the knitting needles 7Fe and 7Be forming the end stitch may be the same as or different from the sinker 11 for the end stitch or the sinker 12 for pile knitting, or may be absent. . The sinker 14 on the upstream side of the knitting needles 7Fs and 7Bs serving as the starting ends may not be provided.

4 is a front view, a top view, and a left side view showing the shape of the end stitch sinker 11 of the flat knitting machine 1 for pile knitting of FIG. ) are compared and shown in (b) as a front view, a top view, and a left view. (c) compares and shows the poles 11a and 12a for piles and the butts 11b and 12b. In the front view and the plan view, the tip portion shown on the right side of the drawing acts upon formation of the stitch. This action is controlled by driving to the tip sides 11d and 12d, the butt sides 11e and 12e and the tip sides 11f and 12f. The protrusion amount of the butt 11b of the sinker 11 for end stitching is smaller than the protrusion amount of the butt 12b of the sinker 12 for pile knitting. The end stitch sinker 11 and the pile knitting sinker 12 are driven by a common sinker cam 22, and due to the difference in the amount of protrusion, Controls can be distinguished together.

The sinker 11 for the end stitch has only a pile pole 11a at the tip end, and does not have a portion where the base thread 31 hangs when the end stitch is formed. On the other hand, the sinker 12 for pile knitting has, together with the pile pawls 12a, at the distal end portion of the base yarn pawl 12c to which the base yarn 31 is caught when the end stitch is formed. Further, as shown in (c), the pile pawl 11a of the sinker 11 for end stitching is for forming a sinker loop 38e with respect to the pile pawl 12a of the sinker 12 for pile knitting. The edge portion 11g is inclined at the inclination angle [theta]. The sinker 11 for the end stitch and the sinker 12 for knitting the pile are used to enter the needle bed gap 2 in the direction from the left to the right of the drawing. As shown in Fig. 2, the forward/backward direction of the knitting needle 7 is inclined at an angle of 45 degrees with respect to the vertical direction indicated by the virtual center plane 2a. The advancing and retreating directions of the sinker 11 for end stitching and the sinker 12 for pile knitting are orthogonal to the advancing and retreating direction of the knitting needle 7 . Therefore, the entry direction from the left to the right in FIG. 4 is an oblique downward direction inclined by 45 degrees with respect to the vertical downward direction in the needle bed gap 2 . When the inclination angle [theta] becomes 45 degrees, the edge portion 11g becomes horizontal, and the sinker loop 38e becomes easy to engage, but the resistance at the time of disengagement increases, making it difficult to detach. Since the edge portion 11g has an inclination angle that is less than 45 degrees (θ), for example, about 30 degrees larger than the obliquely downward direction in which the tip part enters the needle bed gap 2, the pile seal 32 ), after forming the sinker loop 38e, it becomes difficult to separate, and the coupling state can be stably maintained, and can be released when necessary.

Fig. 5 shows the cam arrangement in the flat knitting machine 1 for pile knitting in Fig. 1 when the carriage 20 travels in the left direction with respect to the needle bed 3F as indicated by the arrow , the trajectory in which the portion receiving the drive of the cam moves in the relatively right direction is also shown to correspond to the dashed-dotted line and the broken line. The common trajectory of the sinker 11 for end stitching and the sinker 12 for pile knitting is indicated by a two-dot chain line. Since the basic driving of the knitting needle 7 is made by a needle raising cam 21a, a center cam 21b and a stitch cam 21c acting on the butt, The trajectory of the knitting needle 7 with respect to the knitting cam 21 is represented by a butt and a hook 7a. The sinker cam 22 has an entry edge 22a for entering the sinker 11 for end stitching and the sinker 12 for pile knitting into the needle bed gap 2, and an exit edge for exiting the needle bed gap 2 (22b). The above-described step portion 22c is formed on a part of the exit edge 22b side. Due to the action of the step portion 22c, the trajectory of the sinker 11 for end stitching indicated by the two-dot chain line and the trajectory of the sinker 12 for pile knitting indicated by the broken line are different. Attached to the sinker cam 22, movable cams 23 and 24 are also provided. The movable cams 23 and 24 are operated only when traveling, and act on the terminal sides 11f and 12f and the butt sides 11e and 12e of the sinker 11 for end stitching and the sinker for pile knitting.

Fig. 5 shows phases corresponding to (a), (b), (c) and (d) of Fig. 1 by a, b, c and d, respectively. Prior to a, the movable cam 23 once advances the tip ends of the sinker 11 for end stitching and the sinker 12 for pile knitting into the needle bed gap 2, and presses the stitch at the bottom. installed for The movable cam 24 withdraws the tip ends of the sinker 11 for end stitching and the sinker 12 for pile knitting from the needle bed gap 2, and is particularly coupled to the sinker 11 for end stitches when forming the end stitch. It is installed to release the sinker loop 38e of the pile yarn 32 just before receiving the feed yarn for forming the end stitch in the next course. In a, the butt 7d is guided by the center cam 21b so that the knitting needle 7 enters the needle bed gap 2 the most, and the needle loop that spans the hook 7a latches the latch 7b. It is opened and shifted to the needle shaft side, and it becomes the phase after being cleared. Since a step portion 22c is formed on the exit edge 22b of the sinker cam 22, in d, even if the sinker loop is released in the sinker 12 for pile knitting, the file is piled by the sinker 11 for end stitching. The sinker loop 38e of the seal 32 may not be released.

Fig. 6 shows the cam arrangement in the flat knitting machine 1 for pile knitting of Fig. 1 when the carriage 20 travels in the right direction with respect to the needle bed 3F as indicated by the arrow when the carriage is retrograde. , the trajectory in which the part that is driven by the cam relatively moves in the left direction is also shown to correspond. At the time of retrograde, the knitted fabric is knitted by the needle bed 3B, and the knitting cam 21 basically does not act with respect to the needle bed 3F, so that the sinker 11 for end stitching by the sinker cam 22 is The action does not release the sinker loop 38e. That is, the sinker 11 for end stitching is withdrawn from the needle bed gap 2 under the action of the movable cam 24 only in the phase a at the time of travel, and the sinker loop ( 38e) is released.

Fig. 7 schematically shows a cylindrical pile knitted fabric 30 knitted by the flat knitting machine 1 for pile knitting of Fig. 1 . The stitch by pile knitting is formed from the needle loops 35 and 36 and the sinker loops 37 and 38 by the base yarn 31 and the pile yarn 32, respectively. In the final stitch, the sinker loop 38e of the pile yarn 32 is fed by the knitting needle 7Fe in the next course, and is supported until just before the final stitch is formed. When the sinker 11 for the end stitch is used, the sinker loop 37e of the base yarn 31 becomes shorter than the other sinker loops 37 in the end stitch. In this embodiment, a cylindrical pile knitted fabric is knitted with a constant cylindrical diameter. In the case of changing the diameter of the cylinder, the position at which the end stitch sinker 11 is provided in at least one of the needle beds 3F and 3B may be changed.

In this embodiment, the tip of the sinker 11 for end stitching is advanced and retreated to the needle bed gap 2 by the sinker cam 22 shown in Figs. enters the needle bed gap 2 to form a sinker loop 38e by the pile thread 32 of the end stitch, and after the formation of the sinker loop 38e, the rapid yarn of the knitting yarn for forming the end stitch in the next course It functions as a sinker control means for controlling the pile pawl 11a to stop at the needle bed gap 2 so as to maintain the state in which the sinker loop 38e is engaged until just before receiving. As the sinker control means, an actuator for directly driving the sinker 11 for end stitching may be provided.
