Description

The present invention relates to a flat knitting machine and sinker for pile knitting, capable of knitting pile with ground yarn and pile yarn, and a method of knitting pile with a flat knitting machine.

Conventionally, flat knitting machines capable of pile knitting feed ground yarn and pile yarn to knitting needles, and form pile knit fabric while separating the ground yarn and pile yarn at the tip of a movable sinker. The tip of the sinker has hooks for hanging the ground yarn and the pile yarn, respectively, and the ground yarn is fed first and hooked and fixed on the hook for the ground yarn, and the pile yarn is fed later and hooked and fixed on the hook for the pile yarn, for separation. Such sinkers can form a pile loop by forming a sinker loop made of pile yarn longer than the sinker loop made of ground yarn. Pile knit gloves (see, for example, Patent Document 1) are all pile knit from the fingertips to the wrist, and rubber yarn is inserted by tucks at the wrist, and the pile loop is knitted in a state where it comes out on the inside. Such gloves can be coated with latex or the like on the outside to give them waterproofing or cold protection, or aramid fiber or the like is used for the pile yarn, and the pile is placed on the outside to give them cut resistance and heat resistance. Pile knits can also be made into socks, and by placing the pile loops on the inside, for example, they can be given protection against the cold.

A flat knitting machine that uses movable sinkers to perform pile knitting can efficiently perform pile knitting alone, and if only ground yarn is used without pile yarn, it is also possible to mix in sections where plain knitting is performed. However, if plain knitting is performed using only ground yarn, the pile yarn will pass from the end of the pile knitting section to the start of the next pile knitting section without being woven into the knitted fabric.

Special Publication No. 61-20668

In the pile knit fabric of gloves or socks knitted using the pile knitting method described in Patent Document 1, pile loops are formed over the entire inner or outer surface, and the other surface is free of pile loops. If pile knitting and plain knitting, which does not form pile loops, could be freely mixed, it is expected that new exterior designs and improved anti-slip and gripping effects due to the unevenness can be achieved.

The object of the present invention is to provide a pile knitting flat knitting machine and sinker that can switch between pile knitting and plain stitch knitting, and a pile knitting method using a flat knitting machine.

The sinker has a ground yarn hook and a pile yarn hook at its tip,
In a flat knitting machine for pile knitting, a pile yarn is knitted while a ground yarn fed from a preceding yarn feeder above a yarn feeder and a pile yarn fed from a succeeding yarn feeder are sorted at the tip of a sinker,
The position of the yarn feeder for the ground yarn and the pile yarn above the needle opening is
In the pile knitting to form the pile loops, the yarn feeder for the ground yarn is placed in front and the yarn feeder for the pile yarn is placed behind with a gap between them.
In knitting that does not form a pile loop, the yarn feeder of the trailing pile yarn during pile knitting is moved toward the yarn feeder of the leading ground yarn so that it is in a position where it cannot be sorted by the tip of the sinker.
Each of the switches includes a switching means,
In knitting that does not form pile loops, the ground yarn and pile yarn are caught by the hook of a knitting needle to form a needle loop, and both the ground yarn and pile yarn are hung on the ground yarn hook of a sinker to form a sinker loop, making it possible to knit plain stitch without pile loops.
The pile knitting flat knitting machine is characterized by the above-mentioned.

In the present invention, the knitting needle and the sinker are driven to advance to and retreat from the needle gap by a drive mechanism mounted on a carriage that reciprocates along the longitudinal direction of the needle bed,
the yarn feeder for feeding the ground yarn and the yarn feeder for feeding the pile yarn are provided on a self-propelled carrier that travels independently of a reciprocating carriage and can follow the carriage;
It is characterized by:

In the present invention, the sinker has a push-in portion near the tip end on the tooth gap side, which protrudes downward and is capable of pushing the ground yarn and the pile yarn on the advance/retract path into the tooth gap by advancing into the tooth gap.
It is characterized by:

In the present invention, the sinker advances to the needle gap when the needle density is set, and then re-advances to the needle gap after once retracting from the needle gap, and at least when re-advancing, the pushing portion advances to a position below the needle gap below a top tooth position set on the needle bed.
It is characterized by:

The present invention further relates to a sinker for use in a flat knitting machine for pile knitting, which has a lower ground yarn hook and an upper pile yarn hook at a tip that moves into and out of a knitting gap and is capable of separating ground yarn from pile yarn,
This sinker is characterized by having a push-in portion which protrudes downward from the tip of the ground yarn hook claw at a distance in the direction of retreating from the tooth gap and which, when advancing into the tooth gap, can push the ground yarn and pile yarn on the advance/retract path into the tooth gap.

Further, the present invention includes a knitting needle that advances into the needle gap while rising, and a sinker that advances into and retreats from the needle gap,
The sinker has a ground yarn hook and a pile yarn hook at its tip,
The ground yarn fed in advance above the needle gap and the pile yarn fed in behind are captured by the hook of the knitting needle retracting from the needle gap,
The ground yarn and the pile yarn are sorted at the tip of the sinker, and a sinker loop of the ground yarn and a pile loop of the pile yarn are formed, respectively.
In a pile knitting method using a flat knitting machine,
The yarn feeding positions of the ground yarn and the pile yarn above the needle opening are
In the pile knitting to form the pile loops, the yarn feeder for the ground yarn is placed in front and the yarn feeder for the pile yarn is placed behind with a gap between them.
In knitting that does not form a pile loop, the yarn feeder of the trailing pile yarn during pile knitting is moved toward the yarn feeder of the leading ground yarn so that it is in a position where it cannot be sorted by the tip of the sinker.
Switch between them,
In knitting that does not form pile loops, the ground yarn and pile yarn are caught by the hook of a knitting needle to form a needle loop, and both the ground yarn and pile yarn are hung on the ground yarn hook of a sinker to form a sinker loop, making it possible to knit plain stitch without pile loops.
The pile knitting method is characterized in that

According to the present invention, the pile knitting flat knitting machine can switch between pile knitting, which forms pile loops, and plain knitting, which does not have pile loops, for any knitting needle by operating the switching means. Plain knitting, which can be switched from pile knitting, can be mixed in the middle of a course or in the wale direction on a course-by-course basis, and no crossover yarns are generated. Pile knit fabrics mixed with plain knitting are expected to have a novel appearance design and improved anti-slip and grip effects due to the unevenness.

In addition, according to the present invention, the yarn feeder that feeds the ground yarn and pile yarn is self-propelled, so switching between pile knitting and plain knitting by changing the yarn feed position can be done efficiently.

In addition, according to the present invention, even if an old loop that has been knocked over during plain knitting remains near the tooth gap, it can be pushed below the tooth gap by the pushing part of the sinker. Pushing by the pushing part of the sinker prevents the old loop from remaining when the hook next advances into the tooth gap, making it possible to perform plain knitting stably.

In addition, according to the present invention, the pile knitting flat knitting machine advances the pushing portion of the sinker to a position below the needle gap below the top needle position of the needle bed when re-advancing, so even if the old loop remains near the needle gap, it can be reliably pushed below the needle gap.

Furthermore, according to the present invention, the sinker used in the flat knitting machine for pile knitting can push the old loops that are knocked over and remain near the needle gap during plain knitting down below the needle gap with the pushing section, so plain knitting that is mixed into pile knitting can be performed stably.

Furthermore, according to the present invention, pile knitting and plain knitting can be switched so that they are mixed in the middle of a course or in the wale direction on a course-by-course basis.

FIG. 2 is a layout diagram of the cams that drive the knitting needles 12 and the sinkers 13. FIG. 3 is a simplified cross-sectional side view showing the operation of pile knitting by knitting needles 12 and sinkers 13. FIG. 4 is a simplified cross-sectional side view showing the operation of plain knitting with knitting needles 12 and sinkers 13. FIG. 5 is a partial cross-sectional side view showing the configuration and operation of a push-in portion 13g provided on the sinker 13. As shown in FIG. FIG. 6 is a photograph showing the appearance of a glove 50 knitted by the pile knitting flat knitting machine 1 of FIG.

The following Figures 1 to 6 show the configuration and operation of a pile knitting flat knitting machine 1, which is one embodiment of the present invention. Corresponding parts in each figure are indicated with the same reference numerals, and duplicate explanations may be omitted. Also, for the sake of convenience, parts that are not shown in the figure being explained may be referred to with reference numerals shown in other figures.

Figure 1 shows a simplified configuration of the main parts of a pile knitting flat knitting machine 1 according to an embodiment of the present invention. The pile knitting flat knitting machine 1 has front and rear needle beds 2. The front and rear needle beds 2 face each other across the needle gap 3 and are arranged so as to be symmetrical with respect to the needle gap center plane 3a. When viewed from above, the part sandwiched between the front and rear needle beds 2 at the needle gap 3 is a rectangle that is elongated in the depth direction of the figure. This depth direction will be referred to as the longitudinal direction below. Each needle bed 2 has a base plate 4 and needle plates 5 that are erected at regular intervals in the longitudinal direction of the base plate 4. A stitch suppressing rod 6 is arranged on the needle gap 3 side of the base plate 4. The stitch suppressing rod 6 is used to knit finger pouches of gloves while overlapping them, as described in JP 2013-019062 A, for example. A sinker bed 7 is arranged above the needle gap 3 side of each needle bed 2. Above the needle gap 3, yarn feeders 8 and 9 are arranged, which feed ground yarn 10 and pile yarn 11 for pile knitting, respectively. A yarn guide rail extending in the longitudinal direction is installed above the yarn feeders 8 and 9. A track is provided on the yarn guide rail, which supports the carrier so that it can run in the longitudinal direction. The yarn feeders 8 and 9 are each provided at the lower end of a yarn feeder that hangs down from the carrier.

The needle groove is formed between the needle plates 5 of the needle bed 2, and the knitting needle 12 is accommodated in a slidable state. The knitting needle 12 has a hook 12a at the tip on the tooth gap 3 side. This knitting needle 12 is a latch needle, and the hook opening on the side away from the tooth gap 3 by the hook 12a is opened and closed by the latch 12b. The knitting needle 12 slides in an inclined direction such that the hook 12a rises while advancing into the tooth gap 3 and descends while retracting. A sinker 13 is arranged on the sinker bed 7 so as to be in the middle of the adjacent knitting needles 12. The sinker 13 has an advancement surface 13a and a withdrawal surface 13b, and is driven by a sinker cam 30 described later so that the tip, which has a pile yarn hook 13c and a ground yarn hook 13d, advances and retreats to the tooth gap 3. The sinker 13 slides in an inclined direction such that it descends while advancing into the tooth gap 3 and ascends while retracting. The thin dashed line indicates the state where the tip is furthest into the tooth gap 3.

Figure 2 shows the arrangement of the knitting cam 20 and sinker cam 30, which are the drive mechanism for driving the knitting needle 12 and sinker 13. Such a cam arrangement is basically described in Patent Publication No. 5079682 and the like, and is provided on a carriage that moves back and forth in the longitudinal direction of the needle bed 2. The carriage has cam plates facing the needle bed 2 and the sinker bed 7, respectively, and the knitting cam 20 is mounted on the cam plate facing the needle bed 2. The knitting cam 20 includes a guide cam 21, a rubber cam 22, a knitting cam 23, a needle raising cam 24, a middle cam 25, a top cam 26, a knitting cam 27 for knitting, a stitch cam 28, and a guide cam 29. When the carriage travels to the left of the figure and performs pile knitting or plain knitting, the knitting cam 20 acts on the butt of the knitting needle 12, and drives as shown by the locus 12c. The hook 12a advances and retreats to the tooth gap 3 along a trajectory that is the same as the trajectory 12c but is shifted toward the tooth gap 3 by the distance between the butt and the hook 12a.

A sinker cam 30 is mounted on the cam plate facing the sinker floor 7. The sinker cam 30 has an advance cam surface 30a and a retract cam surface 30b. As shown by the dashed lines on the right side of the figure, the advance cam surface 30a and the retract cam surface 30b press the advance surface 13a and the retract surface 13b of the sinker 13, respectively. Movable cams 31 and 32 are provided attached to the sinker cam 30. The movable cam 31 is a bat-shaped part of the sinker 13 where the retract surface 13b is provided, and presses the surface facing the retract surface 13b in the direction of advancing into the tooth gap 3. This pressure causes the sinker 13 to become a mountain advancing toward the tooth gap 3, and the subsequent retract cam surface 30b causes the sinker 13 to become a valley retracting from the tooth gap 3 to the sinker floor 7. The movable cam 32 is hidden inside the sinker cam 30 when the carriage travels to the left and does not function. Therefore, the sinker 13 is driven by a combination of the advance cam surface 30a and the movable cam 31 in the advance direction toward the tooth gap 3, and the retract cam surface 30b in the retract direction from the tooth gap 3. This drive causes the front and rear ends of the sinker 13 to follow trajectories 13e and 13f.

The yarn feeding positions 8a, 8b, 8c; 9a, 9b, 9c of the ground yarn 10 and pile yarn 11 by the yarn feeders 8, 9 are set at the positions indicated by triangles based on the position of the knitting cam 20. As with conventional pile knitting, the yarn feeding position 8a of the ground yarn 10 precedes the yarn feeding position 8a of the pile yarn 11 with a gap between them, as with conventional pile knitting. In this embodiment, the yarn feeding position 8b of the ground yarn 10 is set to the same as the yarn feeding position 8a, and the yarn feeding position 9b of the pile yarn 11 is moved closer to the leading side than the yarn feeding position 9a and closer to the yarn feeding position 8b, to perform plain knitting. The ground yarn 10 and pile yarn 11 fed from the yarn feeding positions 8b and 9b are not sorted by the ground yarn hook 13d and the pile yarn hook 13c at the tip of the sinker 13, but both are hooked on the ground yarn hook 13d, making plain stitch knitting without pile loops possible. Plain stitch knitting is possible not only with the yarn feeding positions 8b and 9b, but also when the yarn feeding position 9c of the yarn feeder 9 precedes the yarn feeding position 8c of the yarn feeder 8 within a certain allowable range L. The allowable range L is a range in which the ground yarn 10 and the pile yarn 11 are not both hooked on the pile yarn hook 13c, but both are hooked on the ground yarn hook 13d, and both can be captured by the hook 12a. Within this allowable range L, it does not matter which of the yarn feeders 8 and 9 for the ground yarn 10 and the pile yarn 11 precedes, or they may be in the same phase.

In this embodiment, the carriers of the yarn feeders 8 and 9 are self-propelled and can run independently of the carriage, so it is easy to switch between the yarn feeder positions 8a and 9a for pile knitting and the yarn feeder positions 8b and 9b for plain knitting. The action of the sinker 13 for pile knitting and plain knitting is characterized by positions A and B in the figure. Position A is a stitch-determining position where a new loop is formed by the needle loop hooked on the hook 12a of the knitting needle 12 retracted from the needle gap 3 by the retraction of the stitch cam 28 and the sinker loop received at the tip of the sinker 13. Position B is a re-advancement position where the sinker 13 retracts from the needle gap 3 to the sinker bed 7 side at position C after position A, and then advances again to the needle gap 3 side to push in the sinker loop. When the pile knitting flat knitting machine 1 re-advances at least at position B, the sinker 13 pushes the sinker loop below the tooth gap 3, making it easier for the knocked-over old loop to move below the tooth gap 3.

3 and 4 respectively show the state of pile knitting and plain knitting by the operation of the sinker 13 at positions A and B in Fig. 2. As shown in Fig. 3, at the stitch setting position A, in pile knitting, the ground yarn 10 and the pile yarn 11 are sorted by being hooked on the ground yarn hook 13d and the pile yarn hook 13c, respectively, and become the sinker loop of the new loop 40. As shown in Fig. 4, at the stitch setting position A, in plain knitting, both are hooked on the ground yarn hook 13d and become the needle loop of the new loop 40, but are not hooked on the pile yarn hook 13c. The needle loop held by the hook 12a before the new loop 40 was formed becomes the old loop 41. When the hook 12a advances to the needle gap 3 by being driven by the needle raising cam 24 and the center cam 25 to receive the ground yarn 10 and pile yarn 11, the needle loop of the old loop 41 moves relative to the knitting needle 12, opens the latch 12b, moves to the needle stem side, and is cleared from the hook 12a. When the stitch cam 28 retracts the knitting needle 12, the cleared old loop 41 advances relatively to the needle gap 3 side, closes the latch 12b, climbs over the hook 12a, and is knocked over to the needle gap 3 side.

As shown in FIG. 2, at position C between the stitching position A and the re-advancement position B, the sinker 13 temporarily retreats from the tooth gap 3 to the sinker bed 7. At this time, the pile yarn 11 that was held by the pile yarn hook 13c in the pile knitting of FIG. 3 either leaves the pile yarn hook 13c and moves to the ground yarn hook 13d, or leaves the ground yarn hook 13d. When the sinker 13 starts to re-advance from position C, the pile yarn 11 that has moved to the ground yarn hook 13d is pushed up to position B while still being hooked. The pile yarn 11 that once escaped is also pierced by the re-advancement ground yarn hook 13d, becomes hooked on the ground yarn hook 13, and is pushed up to position B. This pushing pushes the ground yarn 10 and the old loop 41 below the tooth gap 3. The pile yarn 11 that was hooked on the ground yarn hook 13d comes off the tip of the sinker 13 as the sinker 13 retracts after position B, forming a pile loop. In the plain stitch knitting shown in FIG. 4, both the ground yarn 10 and the pile yarn 11 come off the ground yarn hook 13d at position C, and do not remain at the tip of the sinker 13 even when it re-advances to position B, resulting in a plain stitch stitch with no pile loops. As shown in FIG. 4, the sinker 13 of this embodiment has a pusher 13g near the tip that protrudes downward and can push the ground yarn 10 and pile yarn 11 on the advance/retract path toward the needle gap 3 as it advances to the needle gap 3.

Figure 5 shows the push-in portion 13g provided on the sinker 13. For convenience of explanation, the direction of advancement into the tooth gap 3, which is inclined downward in Figure 1, is changed in angle to become horizontal to the right in Figure 4. The push-in portion 13g is provided at a position of distance H from the tip of the ground yarn hook 13d. The push-in portion 13g in this embodiment is in the shape of a step that protrudes downward in the figure while inclining by a height G, but it can also be in other shapes such as a vertical shape, a curved shape, or a hook shape. By providing the push-in portion 13g, when the sinker 13 re-advances into the tooth gap 3, the ground yarn 10 and pile yarn 11 on the advance/retract path can be pushed toward the tooth gap 3. The shape of the push-in portion 13g is selected so as not to interfere with pile knitting, and may be different depending on the ground yarn 10 and pile yarn 11 used.

In the flat knitting machine 1 for pile knitting of this embodiment, the stitch stop rod 6 is used on the needle mouth 3 side of the needle bed 2, so the upper end of the stitch stop rod 6 on the needle mouth 3 side acts as the top tooth 6a, and the direction of the knitted fabric connected to the knocked over old loop 41 is bent downward. Depending on the configuration of the needle bed 2, a wire that penetrates in the longitudinal direction may become the top tooth. As shown in Figure 4 (B), in plain knitting, both the ground yarn 10 and the pile yarn 11 are removed from the ground yarn hook 13d of the sinker 13, so if plain knitting continues for several courses, the needle loop of the knocked over old loop 41 may remain in front of the advance direction of the hook 12a without passing the top tooth 6a. When the hook 12a advances into the tooth gap 3 and rises in the next knitting operation, the retained old loop 41 is pushed up by the top of the hook 12a or caught again in the hook 12a, causing knitting defects. Even if the old loop 41 is retained, the pushing section 13g can push it below the tooth gap 3 at the re-advance position B to eliminate the retention. In order to reliably push it below the tooth gap 3, the sinker 13 is pushed down so that the pushing section 13g is at a position a depth D below the position of the top tooth 6a. Note that the sinker 13 does not advance and retreat in a linear direction as in this embodiment, but advances and retreats including swinging, and even when pile knitting is performed while sorting at the tip, if a pushing section is provided, the retention of the old loop in plain knitting can be eliminated.

Figure 6 shows the appearance of a glove 50 knitted as a sample. The glove 50 is knitted using the same kind of yarn for the ground yarn 10 and the pile yarn 11, and has finger pouches for the thumb 51, index finger 52, middle finger 53, ring finger 54 and little finger 55, as well as a palm 56 and a wrist 57. The thumb 51, index finger 52 and palm 56 are alternately knitted with pile knitting and plain knitting in two courses in the wale direction, forming an uneven striped pattern, which is expected to have an anti-slip effect. Since plain knitting is knitted with both the ground yarn 10 and the pile yarn, no jumping yarn of the pile 11 is generated. The middle finger 53, ring finger 54, little finger 55 and wrist 57 are all pile knitted, and rubber yarn is inserted into the wrist 57 using the rubber ridge cam 22 in Figure 2. The back side of the glove 50 can be knitted entirely with pile knitting or plain knitting in a similar manner. By using different yarns for the ground yarn 10 and pile yarn 11, it is possible to diversify the appearance and function of gloves and socks. Mixing plain stitch knitting with pile knitting also has the effect of reducing the consumption of pile yarn 11.

In this embodiment, the yarn feeder 8 for the ground yarn 10 and the yarn feeder 9 for the pile yarn 11 are moved by self-propelled carriers, so that switching between pile knitting and plain knitting due to differences in yarn feed positions can be easily performed. This switching can be performed even in the middle of one course by stopping the carriage and carrier once and changing the yarn feed position. To mix pile knitting and plain knitting in the wale direction on a course-by-course basis, the yarn feed position can be switched when reversing the running direction of the carriage and carrier at the end of the knitting width. The control unit of the pile knitting flat knitting machine 1 controls the running of the carriage and carrier to become a switching means for switching between pile knitting and plain knitting. Even in the case of a carrying type in which the carrier is carried by the carriage, switching between pile knitting and plain knitting is possible by switching the carrying position of the carriage. However, the carriage must have two positions for carrying the carrier, one for pile knitting and one for plain knitting, so four positions are required for the carriage to travel back and forth, and the carriage needs to make extra runs to switch, which reduces knitting efficiency. When using a carrying carrier, the control unit of the flat knitting machine, which controls the carriage travel and the switching of the carrier carrying, becomes the switching means.

As described above, the pile knitting flat knitting machine 1 of this embodiment includes a knitting needle 12 that advances into the tooth gap 3 while ascending, and a sinker 13 that advances into the tooth gap 3 while descending. The sinker 13 has a ground yarn hook 13d and a pile yarn hook 13c at its tip. The knitting needle 12 captures the ground yarn 10, which is fed in advance above the tooth gap 3, and the pile yarn 11, which is fed in the following, with a hook 12a that exits from the tooth gap 3. In pile knitting, the ground yarn 10 and the pile yarn 11 are sorted at the tip of the sinker 13, and a sinker loop of the ground yarn 10 and a pile loop of the pile yarn 11 are formed, respectively. In knitting to form a pile loop, the feeding positions of the ground yarn 10 and the pile yarn 11 above the tooth gap are set so that the yarn feeder 8 of the ground yarn 10 advances and the yarn feeder 9 of the pile yarn 11 follows with a gap therebetween. In knitting that does not form pile loops, the yarn feeder 8 for the ground yarn 10 and the yarn feeder 9 for the pile yarn 11 are switched so that the yarn feeder 9 for the pile yarn 11, which was trailing during pile knitting, is moved toward the yarn feeder 9 for the leading ground yarn 10, and is positioned within a range where it cannot be sorted by the tip of the sinker 13. In knitting that does not form pile loops, the ground yarn 10 and the pile yarn 11 are captured by the hook 12a of the knitting needle 12 to form a needle loop, and are hooked on the ground yarn hook 13d of the sinker 13 to form a sinker loop, making it possible to knit plain stitch without pile loops.
