Abstract

The present invention makes it possible to switch and mix pile knitting and plain stitch knitting. At stitch decision position A, in the plain stitch knitting, both base yarn (10) and pile yarn (11) are caught on a base use pawl (13d) and become a sinker loop of a new loop (40) and fall out of the base use pawl (13d) up to re-entry position B of a sinker (13). An old loop (41) is cleared by opening a latch (12b) and moving to an inter-needle side when a hook (12a) advances into a needle bed gap (3). In addition, when a knitting needle (12) is retracted from the needle bed gap (3), the old loop (41) relatively advances toward the needle bed gap (3) and passes over the hook (12) while closing the latch (12b), thereby knocking over toward the needle bed gap (3). Even if the knocked-over old loop (41) stays near the needle bed gap (3), it is possible to be pressed in below the needle bed gap (3) by a press-fitting unit (13g) of the sinker (13) up to the re-entry position B. In the pile knitting, the base yarn (10) and the old loop (41) can be press-fitted by press-fitting the pile yarn (11) caught on the base use pawl (13d) at the re-entry position B.

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

In a flat knitting machine capable of conventional pile knitting, a pile knitting fabric is formed by supplying ground yarn and pile yarn to a knitting needle and separating the pile yarn from the tip of the movable sinker. The tip of the sinker is provided with a pawl for hanging the base yarn and the pile yarn, and the base yarn is fed first and hooked to the pole for base yarn, and then the pile yarn is fed and connected to the pole for pile yarn. Separate by hooking and combining . Such a sinker can be made into a pile loop by forming a sinker loop of pile yarn longer than a sinker loop of base yarn. Pile knitted fabric gloves (for example, see Patent Document 1) are made of pile knitting from the fingertips to the wrist, the rubber thread is inserted into the wrist by the tuck, and the pile loop is facing inward. organized These gloves can be coated with latex or the like on the outside to have waterproof or cold protection functions, or have incision resistance or heat resistance by using aramid fibers or the like for the pile yarn and turning the pile to the outside. The pile knitted fabric can also be formed into a sock, and can have a cold protection function, for example, by making the pile loop inside.

A flat knitting machine that uses a movable sinker for pile knitting can only efficiently perform pile knitting, and if only the base yarn is used without using pile yarn, the plain stitch knitting section can be mixed. However, when plain stitch knitting is performed with only the ground yarn, the pile yarns are not incorporated into the knitted fabric and extend from the end of the pile knitting section to the beginning of the next pile knitting section.

1 to 6 show the configuration and operation of flat knitting machine 1 for pile knitting as one embodiment of the present invention. Corresponding parts in each drawing are denoted by the same reference numerals, and overlapping descriptions may be omitted. In addition, for convenience of description, reference numerals described in other drawings may be referred to with respect to parts not described in the drawings to be described.

(Example)

1 shows a simplified configuration of the main parts of a flat knitting machine 1 for pile knitting, which is one embodiment of the present invention. A flat knitting machine 1 for pile knitting has needle beds 2 on the front and back. The front and rear needle beds 2 face each other with the needle bed gap 3 interposed therebetween, and are arranged so as to be plane symmetrical with respect to the needle bed gap central plane 3a. A portion between the front and rear needle beds 2 as the needle bed gap 3 has an elongated rectangular shape in the depth direction in the drawing when viewed from above. About this depth direction, it describes as a longitudinal direction below. Each needle bed 2 includes a substrate 4 and needle plates 5 installed upright at regular intervals in the longitudinal direction of the substrate 4 . On the side of the needle bed gap 3 of the substrate 4, a stitch suppressor 6 is disposed. The stitch restraint interval 6 is used for knitting while overlapping between the finger parts of the glove, as described in, for example, Japanese Unexamined Patent Publication No. 2013-019062. Above each needle bed 2 on the side of the needle bed gap 3, a sinker bed 7 is disposed. Above the needle bed gap 3, yarn feeders 8 and 9 are disposed, and ground yarn 10 and pile yarn 11 for pile knitting are respectively fed. Above the yarn feeders 8 and 9, a yarn guide rail extending in the longitudinal direction is installed. A track is formed on the yarn guide rail to support the carrier to run in the longitudinal direction. Yarn feeders 8 and 9 are formed at the lower end of the yarn feeder descending from the carrier, respectively.

Between the needle plates 5 of the needle bed 2 becomes a needle groove, and the knitting needles 12 are accommodated in a sliding state. The knitting needle 12 has a hook 12a at its tip on the needle bed gap 3 side. This knitting needle 12 is a latch needle, and the claw portion of the hook 12a that opens to the side away from the needle bed gap 3 is opened and closed by the latch 12b. Sliding of the knitting needle 12 is performed in an inclined direction in which the hook 12a advances into the needle bed gap 3 and ascends and descends while retreating. In the sinker bed 7, a sinker 13 is disposed so as to be in the middle of adjacent knitting needles 12. The sinker 13 has an advancing surface 13a and a retracting surface 13b, and the tip having the pile use pole 13c and the base use pole 13d advances and retreats to the needle bed gap 3, which will be described later. It is driven by the sinker cam 30. The sliding of the sinker 13 by this driving is performed in an inclined direction in which it descends while advancing into the needle bed gap 3 and rises while retreating. A thin broken line in the figure indicates a state in which the tip has most advanced into the needle bed gap 3.

2 shows the arrangement of the knitting cam 20 and sinker cam 30, which are driving mechanisms for driving the knitting needle 12 and the sinker 13. The arrangement of such a cam is basically described in Japanese Patent No. 5079682 and the like, and is installed on a carriage reciprocating in the longitudinal direction of the needle bed 2 . The carriage has a cam plate facing the needle bed 2 and the sinker bed 7, respectively, and a knitting cam 20 is mounted on the cam plate facing the needle bed 2. The knitting cam 20 includes a guide cam 21, an elastic lasing cam 22, a knitting start cam 23, a needle lasing cam 24, a center cam 25, a bridge cam 26, and a knitting start cam. It includes a cam 27, a stitch cam 28, and a guide cam 29. The knitting cam 20 acts on the butt of the knitting needle 12 to perform driving indicated by the trajectory 12c when pile knitting or plain stitch knitting is performed while the carriage travels in the left direction in the drawing. The hook 12a advances and retreats to the needle bed gap 3 by the locus of moving the locus 12c toward the needle bed gap 3 side by the distance between the butt and the hook 12a.

The sinker cam 30 is mounted on the cam plate facing the sinker bed 7. The sinker cam 30 has an advancing cam surface 30a and a retracting cam surface 30b. As indicated by broken lines on the right side of the drawing, the advancing cam surface 30a and the retracting cam surface 30b press the advancing surface 13a and the retracting surface 13b of the sinker 13, respectively. Attached to the sinker cam 30, movable cams 31 and 32 are installed. The movable cam 31 presses the surface opposite to the recessed surface 13b in the direction of advancing into the needle bed gap 3 by the butt-shaped portion of the sinker 13 where the recessed surface 13b is formed. . By this pressurization, the sinker 13 becomes a floor advancing toward the needle bed gap 3 side, and then the sinker 13 retreats from the needle bed gap 3 to the sinker bed 7 by the retracting cam surface 30b it becomes a goal The movable cam 32 remains hidden in the sinker cam 30 when the carriage travels in the left direction, and does not act. Therefore, the driving of the sinker 13 is driven in the advance direction to the needle bed gap 3 by the advancing cam surface 30a and the movable cam 31, and from the needle bed gap 3 by the retracting cam surface 30b. It is composed of a combination of driving in the retracting direction of By this driving, the tip and end of the sinker 13 pass through the trajectories 13e and 13f.

The yarn feeding positions 8a, 8b, 8c; 9a, 9b, 9c of the base yarn 10 and the pile yarn 11 by the yarn feeders 8 and 9 are triangular based on the arrangement of the knitting cam 20. set to the indicated location. With respect to the yarn feeding positions 8a and 9a at the time of pile knitting, the yarn feeding position 8a of the base yarn 10 precedes and the yarn feeding position 9a of the pile yarn 11 follows at intervals, according to the prior art. Same as file organization. In this embodiment, the yarn feeding position 8b of the base yarn 10 is the same as the yarn feeding position 8a, and the yarn feeding position 9b of the pile yarn 11 is moved to the preceding side from the yarn feeding position 9a, By approaching the position 8b, plain stitch knitting is performed. The base yarn 10 and the pile yarn 11 fed from the yarn feeding positions 8b and 9b cannot be separated from the base yarn 13d and pile yarn 13c at the tip of the sinker 13, so both is hooked to the ground pole 13d to perform plain stitch knitting without pile loops. In plain stitch knitting, as long as the yarn feeding positions 8b and 9b are within a certain allowable range L, the yarn feeding position 9c of the yarn feeding ball 9 precedes the yarn feeding position 8c of the yarn feeding ball 8, It is also possible. The allowable range L is such that both the ground yarn 10 and the pile yarn 11 are not caught on the pile use pole 13c, both are caught on the ground use pole 13d, and both are caught on the hook 12a. range that can be captured. As long as it is within this allowable range (L), either of the yarn feeders 8 and 9 of the ground yarn 10 and the pile yarn 11 may lead, and may have the same phase.

In this embodiment, since the carriers of the yarn feeders 8 and 9 are of a self-propelled type that can run independently of the carriage, the yarn feeding positions 8a and 9a of pile knitting and plain stitch knitting It is also easy to switch between the yarn feeding positions 8b and 9b. The actions of the sinker 13 for pile knitting and plain stitch knitting can be characterized by positions A and B in the drawing. Position A is a needle loop caught on the hook 12a of the knitting needle 12 retracting from the needle bed gap 3 by retraction by the stitch cam 28 and a sinker loop received from the tip of the sinker 13 This is the stitch determination position where a new loop is formed. In position B, after position A, the sinker 13 retreats from the needle bed gap 3 to the sinker bed 7 side at position C, advances again to the needle bed gap 3 side, and presses the sinker loop. is the location of In the flat knitting machine 1 for pile knitting, the sinker loop is pressed downward of the needle bed gap 3 by the sinker 13 at least at the time of re-entry at position B, so that the knocked over loop ( The old loop) makes it easy to move downward of the needle bed gap 3.

3 and 4 show states in which pile knitting and plain stitch knitting are performed by the operation of the sinker 13 at positions A and B in FIG. 2, respectively. As shown in Fig. 3, at the stitch determination position A, the ground yarn 10 and the pile yarn 11 are hooked on the ground use pole 13d and the pile use pole 13c, respectively, in pile knitting, and separated while forming a new loop ( 40) becomes a sinker loop. As shown in Fig. 4, at the stitch determining position A, in plain stitch knitting, both sides are hooked on the ground poles 13d and become needle loops of the new loop 40, but are not hooked on the pile poles 13c. The needle loop supported by the hook 12a before the new loop 40 is formed becomes the old loop 41 . When the hook 12a advances to the needle bed gap 3 driven by the needle raising cam 24 and the center cam 25 to receive the feeding yarn of the base yarn 10 and the pile yarn 11, the old loop The needle loop of (41) opens the latch 12b by moving relative to the knitting needle 12, shifts to the interstitch side, and is cleared from the hook 12a. The cleared loop 41, when the stitch cam 28 retracts the knitting needle 12, relatively advances toward the needle bed gap 3 side and climbs over the hook 12a while closing the latch 12b. It is knocked over to the needle bed gap (3) side.

As shown in Fig. 2, at position C between the stitch determination position A and the re-entry position B, the sinker 13 is once retreated from the needle bed gap 3 toward the sinker bed 7 side. At this time, the pile yarn 11 coupled to the pile use pole 13c by the pile organization of FIG. 3 escapes from the pile use pole 13c and moves toward the ground use pole 13d, or the ground use pole ( 13d) is also missing. When the sinker 13 starts re-entry at position C, the pile yarn 11 that has moved to the base pole 13d is pushed in to position B as it is caught. The pile yarn 11 once removed is also caught by the re-entry pawl 13d, and is press-fitted to position B while caught on the pawl 13d. By this press-fit, the base yarn 10 and the loop 41 are press-fit below the needle bed gap 3 . The pile yarn 11 hooked on the ground pole 13d comes off the tip of the sinker 13 when the sinker 13 next to the position B is retracted and becomes a pile loop. In the plain stitch knitting shown in Fig. 4, both the ground yarn 10 and the pile yarn 11 fall out of the ground pole 13d at position C, and do not remain at the tip of the sinker 13 even when they are re-entered to position B. Since it is not formed, it becomes a stitch of plain stitch knitting in which no pile loop is formed. As shown in Fig. 4, the sinker 13 of this embodiment protrudes downward in the vicinity of the tip, and by advancing into the needle bed gap 3, the base yarn 10 and the pile yarn 11 on the forward and backward path are removed. A press-fitting portion 13g capable of being press-fitted into the needle bed gap 3 side is provided.

5 shows press-fitting portions 13g and 13h formed in the sinker 13. For convenience of explanation, the direction of advancement into the needle bed gap 3 inclined downward in FIG. 1 is indicated by changing the angle so as to be horizontal to the right in FIG. 4 . As shown in Fig. 5(a), the press-fitting portion 13g is formed at a distance H from the front end of the ground pawl 13d. The press-fitting portion 13g of the present embodiment has a stepped shape protruding downward by a height G in the figure, but has other shapes such as a vertical shape, a curved shape, and a hooked shape shown in Fig. 5(b). It is also possible. By forming the press-fit portion 13g, the base yarn 10 and the pile yarn 11 on the advance and retreat path are inserted into the needle bed gap 3 when the sinker 13 to position B re-enters the needle bed gap 3. ) side can be pressed. The shape of the press-in portion 13g is selected so as not to interfere with pile knitting, and may be different depending on the ground yarn 10 and the pile yarn 11 used. As shown in Fig. 5(b), if the shape of the press-fitting portion 13h is a hook shape where the bottom portion 13i is the deepest, the base yarn 10 or the pile yarn 11 on the forward and backward path is needled. It is possible to reliably press-fit the needle bed gap downward without missing the upper part of the bed gap 3.

In the flat knitting machine 1 for pile knitting of this embodiment, since the stitch suppression interval 6 is used on the needle bed gap 3 side of the needle bed 2, the needle bed gap of the stitch suppression interval 6 ( 3) The upper end on the side acts as an edge 6a, so that the direction of the knitted fabric following the knocked-over gloop 41 is bent downward. Depending on the configuration of the needle bed 2, a wire or the like penetrating in the longitudinal direction may serve as an edge. In plain stitch knitting as shown in FIG. 4(B), since both the ground yarn 10 and the pile yarn 11 are excluded from the ground pole 13d of the sinker 13, the plain stitch knitting continues for multiple courses. In this case, there is a fear that the needle loop of the knocked-over gloop 41 may stay in the forward direction of the advancing direction of the hook 12a without exceeding the edge 6a. The remaining loop 41 is pushed up by the top of the hook 12a or captured again in the hook 12a when the hook 12a advances to the needle bed gap 3 and rises in the next knitting operation, causes misalignment. In the press-fitting portions 13g and 13h shown in Figs. 5(a) and (b), even if the old loop 41 stays, the stay can be eliminated by pushing it downward into the needle bed gap 3 at the re-entry position B. there is. In order to ensure the downward press-fitting of the needle bed gap 3, the sinker 13 is positioned such that the press-fitting portion 13g shown in Fig. 5(a) is positioned downward by a depth D from the position of the edge 6a ) to push down. Further, the press-fitting portion 13h shown in Fig. 5(b) pushes down the sinker 13 so that the bottom portion 13i is positioned below the position of the edge 6a. In addition, as the sinker 13, even in the case of pile knitting while separating from the tip, by not advancing and retreating in a linear direction as in the present embodiment, but by advancing and retreating including swinging, forming a press-in portion can improve the efficiency in plain stitch knitting. Residency of Guloop can be eliminated.

Fig. 6 shows the appearance of the glove 50 knitted as a sample. The glove 50 is knitted using the same type of yarn as the ground yarn 10 and the pile yarn 11, and the thumb 51, index finger 52, middle finger 53, ring finger 54, and small finger 55 ), and a palm 56 and a wrist 57. The thumb 51, the index finger 52, and the palm 56 alternately repeat pile knitting and plain stitch knitting in the wale direction for two courses at a time to form uneven stripes, and an anti-slip effect can also be expected. In plain stitch knitting, since both the ground yarn 10 and the pile yarn 11 are incorporated, cross yarns of the pile yarn 11 do not occur. The entire course of the middle finger 53, ring finger 54, small finger 55, and wrist 57 is made of pile knitting, and a rubber thread is applied to the wrist 57 using the elastic lasing cam 22 of FIG. are inserting On the back side of the hand of the glove 50, plain stitch knitting may be similarly mixed with pile knitting, or it may be all pile knitting. If different yarns are used as the base yarn 10 and the pile yarn 11, the appearance or function of gloves or socks can be developed in various ways. When plain stitch knitting is mixed with pile knitting, there is also an effect of reducing the amount of consumption of pile yarn 11.

In this embodiment, since the yarn feeder 8 of the base yarn 10 and the yarn feeder 9 of the pile yarn 11 are moved by a self-propelled carrier, pile knitting and plain stitch knitting due to differences in yarn serving positions conversion can be facilitated. This switching can be carried out by temporarily stopping the carriage and the carrier even in the middle of one course and changing the yarn feeding position. In order to mix pile knitting and plain stitch knitting in the wale direction of course units, it is only necessary to switch the yarn feeding position when the running directions of the carriage and carrier are reversed at the ends of the knitting width. The control unit of the flat knitting machine 1 for pile knitting controls the running of the carriage and the carrier, and serves as switching means for switching between pile knitting and plain stitch knitting. Even in an interlocking type in which the carrier moves along the carriage, it is possible to switch between pile knitting and plain stitch knitting by switching the interlocking position of the carriage. However, since the interlocking position of the carriage by the carriage needs to be formed in two places for pile knitting and plain stitch knitting, and it is necessary to form it in four places for the carriage to and fro, the carriage has an extra run for switching This is necessary, and the knitting efficiency is lowered. In the case of using an interlocking type carrier, the control unit of the weft knitting machine that controls the switching between the running of the carriage and the interlocking of the carrier serves as a switching means.

As described above, the flat knitting machine 1 for pile knitting of this embodiment includes a knitting needle 12 that advances to the needle bed gap 3 while rising, and a sinker 13 that advances to the needle bed gap 3 while descending. do. The sinker 13 has a base pole 13d and a pile pole 13c at the tip. The knitting needle 12 has a hook 12a for retracting the base yarn 10 fed ahead of the needle bed gap 3 and the pile yarn 11 fed later from the needle bed gap 3 capture with In pile knitting, a sinker loop of the ground yarn 10 and a pile loop of the pile yarn 11 are formed, respectively, while the ground yarn 10 and the pile yarn 11 are separated from the tip of the sinker 13. In knitting in which the base yarn 10 and the pile yarn 11 above the needle bed gap form a pile loop, the yarn feeder 8 of the base yarn 10 precedes, and the pile yarn 11 The feeder 9 of the trailing at intervals. In knitting that does not form a pile loop, the feeder ball 8 of the ground yarn 10 and the yarn feeder ball 9 of the pile yarn 11 are the yarn feeder ball of the pile yarn 11 that followed during pile knitting ( 9) is brought closer to the yarn feeder (8) side of the preceding base yarn (10), and the sinker (13) is switched to a position within a range that cannot be separated from the front end. In knitting that does not form a pile loop, the base yarn 10 and the pile yarn 11 are captured by the hook 12a of the knitting needle 12 to form a needle loop, and the base yarn 13d of the sinker 13 By forming a sinker loop over the loop, plain stitch knitting without a pile loop is made possible.
