Abstract

A method for evacuating a knitting yarn and a flat knitting machine are provided to prevent the interference of a portion of the knitting yarn passing in an up-and-down direction and a moving portion of the knitting yarn, even in a feeding state of the knitting yarn from above, by improving the structure of the knitting machine. An interlocking element(13) of an upper yarn feeder(5fua), when a lower yarn feeder(5fd) is stopped, guides an up-and-down portion(6fdv) of a knitting yarn while in a left direction while knitting a knitted fabric. Even though the up-and-down portion of the knitting yarn is disposed at a position, where the up-and-down portion is interfered, by movement of the upper yarn feeder, a horizontal portion(6fdh) of the knitting yarn between a hook member(14) and a yarn guide(10fd) is interfered with the upper yarn feeder if the up-and-down portion of the knitting yarn is coupled to a hook member. When the lower yarn feeder is switched from a stop state to a use state, the lower yarn feeder is used in a feeding state of the knitting yarn from above since the interlocking element and the lower yarn feeder are moved to the hook feeder to cancel the coupling of the knitting yarn.

TECHNICAL FIELD This invention relates to the evacuation method of the knitting yarn at the time of knitting a knitted fabric while spinning yarn from upper direction, and its flat knitting machine.

Background Art Conventionally, in the flat knitting machine, the knitting yarn is driven while driving a knitting needle provided side by side on the needle bed by a cam mechanism mounted on a carriage reciprocating in the longitudinal direction of the needle bed. It supplies and knits the knit fabric. The knitting yarn is supplied to a knitting needle that advances into a needle bed gap from a yarn feeder at the tip of a yarn feeder that moves with the carriage. As a method of supplying yarn to a yarn feeder, the yarn is fed upwards and downwards from a shock absorbing mechanism such as a spring installed on the upper side of the knitting machine, or from the spring via the side of the knitting machine. There is a side yarn that passes in the horizontal direction. The yarn feeder travels along a travel rail provided above the needle bed gap.

Fig. 7 is a diagram showing the configuration of main parts of the hosiery knitting machine 1 as an example of the flat knitting machine of the upper yarn. In the socks knitting machine 1, the front needle bed 2f and the rear needle bed 2b face each other with the needle bed gap 3 interposed therebetween, and four running rails 4fu, 4fd, 4bu, and 4bd are provided above the needle bed gap 3. . One or more yarn feeders 5fua, 5fub, 5fd, 5bu, and 5bd are installed in each of the running rails 4fu, 4fd, 4bu, and 4bd, respectively. Each yarn feeder 5fua, 5fub, 5fd, 5bu, 5bd passes through the knitting yarns 6fua, 6fub, 6fd, 6bu, 6bd from above. The carriage 7 can reciprocate in the longitudinal direction of the front and back needle beds 2f and 2b. The support stand 8 is installed upward from the carriage 7. From the support stand 8, the interlocking pin 9 protrudes laterally. The interlocking pin 9 in the protruding state can, for example, selectively connect the yarn feeder 5fub to the carriage 7, and can suddenly feed the knitting needle that performs the knitting operation by the carriage 7. Although not shown in the drawing, the carriage 7 on the front needle bed 2f is selected from another yarn feeder 5fua provided on the traveling rail 4fu on the upper end and a yarn feeder 5fd on the lower travel rail 4fd, respectively. Interlocking pins are also provided. The carriage on the rear needle bed 2b side is omitted in the drawings, but is provided with an interlocking pin capable of interlocking with each other by selecting yarn feeders 5bu and 5bd provided on the upper and lower traveling rails 4bu and 4bd at the rear, respectively.

In the socks knitting machine 1, the socks are knitted in a tubular shape while the needle beds 2f and 2b before and after are circulated in a yarn knitting system in which both yarns and yarns are steeply fed in parallel. do. Yarn knitting is a yarn feeder which feeds and scans yarns from yarn feeders 5fua and 5fd respectively installed on the upper and lower traveling rails 4fu and 4fd (see, for example, Patent Document 1), or is installed on one traveling rail 4fu. It is made by suddenly injecting and supernatant from 5fua and 5fub (see Patent Document 2, for example). As in Patent Literature 2, when the front yarn feeder 5fua and 5fub are used for injection and addition, for example, the charge yarn feeder 5fd is used to prevent loosening of the knitting end and back The upper yarn feeder 5bu is used for elastic yarn and the lower yarn feeder 5bd is used for color yarn, respectively.

In the following description, when referring to each part, the subscripts such as f, b, fua, fub, fd, bu, and bd may be omitted and may be represented by a sign of numbers only.

In the sock knitting machine 1, the travel rails 4 of the yarn feeder 5, which are interlocked by the interlocking pins 9 from the carriages 7 arranged on the front needle bed 2f and the rear needle bed 2b, are provided above and below, respectively. In the hosiery knitting machine 1, yarn 6 is fed to yarn feeder 5 as an upper yarn, so if one yarn feeder 5 on the side linked by the same carriage 7 passes over the other yarn feeder 5, at least one yarn There is a possibility that the knitting yarn 6, which is upwardly fed to the feeder 5, may be entangled by interfering with one of the other yarn feeders 5 or the interlocking pin 9 and the like. If one yarn feeder 5 is reciprocating and the other yarn feeder 5 is stopped, the knitting yarn 6 is repeatedly jammed, causing problems such as sagging, damage or cutting of the knitting yarn 6. The use of yarn feeder 5 as described above is distinguished between the use of injection and fine yarns for the formation of the main part, while the other yarn feeder 5 escapes the end of needle bed 2 and interferes with yarn 6 and yarn feeder 5. It is made to make it difficult to receive.

In the sock knitting machine 1, an elastic yarn may be inserted into a knitting fabric of a high-knit in an elastic part or the like to knit. As described above, when the rear yarn yarn feeder 5bu is used for feeding the elastic yarn, the rear yarn yarn feeder 5bu is also linked together with the yarn feeders 5fua and 5fub of the previous phase. However, the movement of the rear yarn feeder 5bu does not cause interference even when the front yarn feeders 5fua, 5fub, and 5fd of the previous top and bottom stop.

In addition, the interference between yarn feeder 5 and knitting yarn 6 does not occur in flat knitting machines having side yarns. In the flat knitting machine of the side yarns, the yarn feeder is supplied to the yarn feeder from a shock absorber such as a spring via a side tension device or the like provided on the side end of the needle bed (see, for example, Patent Document 3).

Fig. 8 shows a yarn feeder 5fua with two upper and lower portions 6fdv of the knitting yarn which is steeped from the upper side to the stationary yarn feeder 5fd stationary from the top, reciprocating the upper traveling rail 4fu. In order to prevent interference as shown by the dashed line, it is a figure which shows the example which relays knitting yarn by providing the yarn guide 10rl for relay in the lower side. In the yarn feeder 5fd, the knitting yarn is accepted by the yarn guide 10fd. When relayed, the knitting yarn is supplied as a horizontal portion 6fdh from the yarn guide 10rl for the relay, as indicated by the solid line. Can be. Although the feed to the yarn guide 10rl for relaying is made by the upper and lower 6fdv, if the position of the upper and lower 6fdv indicated by the solid line is outside the moving range of the left feeder 5fua and right move 5fuar of the yarn feeder 5fua, the repetition of interference is avoided. Can be.

The fine knitting may be made of a yarn feeder provided on another traveling rail as shown in Patent Document 1, or may be used of a yarn feeder provided on the same traveling rail as shown in Patent Document 2. Therefore, it is conceivable to convert the yarn feeder which has scanning in common and feeds the yarns between the yarn feeder provided on the same traveling rail as the scanning and the yarn feeder provided on the traveling rail different from the scanning. However, in the case of stopping the lower yarn feeder, the knitting yarn which is upwardly steered interferes with the upper yarn feeder.

As shown by the two-dot chain line in Fig. 8, in the case where the upper and lower portions 6fdv of the yarn to be steered interfer with the upper yarn feeder 5fua that reciprocates, the yarn is fed upward through the yarn guide 10rl for relaying as shown by the solid line. Jams caused by yarn feeder 5fua do not occur. However, in the case of knitting the knitted fabric by reciprocating the lower yarn feeder 5fd, the yarn feeding from the yarn guide 10rl for the relay to the yarn guide 10fd of the yarn feeder 5fd becomes transverse through the horizontal portion 6fdh. There is a problem that the fluctuations of the increase become large.

In the flat knitting machine of the side yarns, in the reciprocation of the yarn feeder, the traveling to one side approaches the steward side, and the traveling to the other side is separated from the steward side. Thus, the pressing / pulling of the knitting yarn occurs due to the approach / release according to the driving direction, thereby increasing the variation of the knitting yarn tension. Variation in the knitting tension causes variation in the size of the stitch to be knitted, making the stitch difficult to be uniform. In Patent Literature 3, the supply of the knitting yarn is controlled in accordance with the change in the direction and the demand amount so as to suppress the fluctuation of the knitting yarn tension and the like. However, adding a device for controlling the supply amount of knitting yarn and preventing tension fluctuation complicates the configuration of the knitting machine and increases the manufacturing cost.

Accordingly, it is an object of the present invention to provide a knitting method and a knitting machine capable of avoiding interference between the knitting yarn and the moving part which pass up and down even in the upper yarn.

The present invention, in the flat knitting machine that supplies a plurality of yarn feeders from above, when the knitting yarn is knitted by suddenly feeding the knitting needle from the yarn feeder selectively linked by a carriage reciprocating in the longitudinal direction of the needle bed As a method of evacuating the yarn fed from the upper side to the yarn feeder stationary on one side or the middle of the range so as not to be interfered by the carriage movement,

The other end side of the moving range is allowed to be relayed to the yarn feeder which stops the knitting yarn supplied from above through a path which is not interfered with when the carriage moves.

When stopping the yarn feeder interfered by the carriage movement, the knitting yarn supplied from above to the yarn feeder to be stopped is guided and relayed to the other end side of the moving range by the carriage movement.

When selectively interlocking the yarn feeder by the carriage, the yarn feeder is interlocked with the carriage to move to the other end side of the moving range to release the relay of knitting, and the yarn feeder directly supplies the knitting yarn from above. How to evacuate knitting.

In addition, the present invention is a flat knitting machine having a plurality of yarn feeders which can be selectively interlocked by a carriage reciprocating in the longitudinal direction of the needle bed and are supplied with knitting yarns from above,

(Example)

1 to 6 are diagrams showing a schematic configuration of a sock knitting machine 11 as an example of an embodiment of the present invention. In the following description, parts corresponding to those in Figs. 7 and 8 are given the same reference numerals, and redundant descriptions are omitted. In addition, since description of the structure of the yarn feeder 5fua and 5fd described next also applies to other yarn feeder, the description is abbreviate | omitted.

Fig. 1 is a view showing the evacuation method of knitting yarn 6 in the sock knitting machine 11 of this embodiment, which corresponds to Fig. 8. Arrangement of each part is basically equivalent to FIG. The yarn feeder 5fd provided on the lower traveling rail 4fd is stopped, and evacuation is performed to prevent interference when the yarn feeder 5fua provided on the upper traveling rail 4fu is moved. Each yarn feeder 5fua and 5fd are provided with the support bodies 12fua and 12fd supported by the traveling rails 4fu and 4fd and slidingly displaced. To each support 12fua and 12fd, the yarn guides 10fua and 10fd which receive the knitting yarns which are upwardly steeped are attached, respectively. When the yarn feeder 5fd stops, the upper and lower portions 6fdv of the knitting yarn 6 interfering with the yarn feeder 5fua are portions upward from the yarn guide 10fd as indicated by the two-dot chain lines.

An accompanying member 13 as a guide member is attached to the support 12fua of the upper yarn feeder 5fua. In addition, when the lower yarn feeder 5fd is stopped at one end or halfway of the travel rail 4fd, the hook member 14 which is a relay member is provided on the other end side of the travel rail 4fd. The height of the interlocking piece 13 is made lower than the hook member 14. The feeder openings 15fua and 15fd are respectively installed at the ends of the Yanfeeder 5fua and 5fd. The feed yarns 15fua and 15fd are provided so as to hang from the supports 12fua and 12fd, respectively, by feeder rods 16aua and 16fd. The yarn guides 10fua and 10fd relay the knitting yarns which are upper yarns to the yarn feeder 15fua and 15fd. Knitting yarns fed from the yarn feed ports 15fua and 15fd to the needle bed gap 3 side are continuously supported by a stitch loop in the knitted fabric or temporarily by a looper or the like.

At the start of the stop of the feeder 5fd, the upper and lower portions 6fdv of the knitting yarn are in a position where interference occurs due to the movement of the upper feeder 5fua, as indicated by a two-dot chain line. The interlocking piece 13 can guide the upper and lower portions 6fdv of the knitting yarn to be coupled to the hook member 14 as indicated by the solid line when the yarn feeder 5fua moves to the left through the broken line. The knitting yarn between the hook member 14 and the yarn guider 10fd of the stopped yarn feeder 5fd becomes the horizontal portion 6fdh, and does not interfere with the reciprocating yarn feeder 5fua. When the yarn feeder 5fd is changed from the stationary state to the use state, as described later, the yarn feeder 5fd can be released by simply moving the yarn feeder to the position of the hook member 14. have.

Fig. 2 is a diagram showing the overall configuration of the hosiery knitting machine 11 from the side. The feed rods 16fua, 16fd, 16fbu, of each yarn feeder 5fua, 5fd, 5bu, and 5bd are fed so that the yarns are fed from the yarn feed port 15 to the needle needles 17f and 17b which advance and exit needlebed gaps 2f and 2b to the opposite needle bed gap 3, respectively. The 16bd are inclined and supported by the supports 12fua, 12fd, 12bu, and 12bd, respectively. Each support 12fua, 12fd, 12bu, 12bd is supported by the running rails 4fu, 4fd, 4bu, 4bd, respectively. Yarn feeders 5fua and 5fd by the movement of the carriages 7f and 7b provided in the needle beds 2f and 2b before and after; Selection of whether or not 5bu and 5bd are interlocked includes: interlocking pins 9fua and 9fd provided on the support stands 8f and 8b; It is made by the appearance of 9bu and 9bd. The yarns which are steeped upwards are each support 12fua and 12fd; Yarn guides 10fua and 10fd installed in 12bu and 12bd; It is taken from 10bu and 10bd and leads to the emergency exit 15. In the arrangement as shown in Fig. 2, the yarn feeders 5fd supported by the lower traveling rails 4fd and 4bd, and the yarn guides 10fd and 10bd of 5bd become the outer side, and the knitting yarns steeped in the yarn guides 10fd and 10bd from the upper side are inside. Thus, interference with the yarn feeders 5fua and 5bu supported by the upper traveling rails 4fua and 4bu cannot be avoided, respectively.

In particular, the yarn feeder 5fua of FIG. 7 (not shown in FIG. 2) is installed on the running rail 4fu of the upper phase, and the yarn feeder 5fua of FIG. 7 is omitted. When the yarn feeder 5fub is used as an additive and the yarn feeder 5fd installed on the running rail 4fd of electric charge is also used as an additive, interference is a problem. In the socks which knit the main part by the knitting yarn of the knitting yarn, the use rate of the yarn feeder 5fua, 5fub, and 5fd is high because the amount of the injection and the spinning yarn is higher than that of the other knitting yarns. The fine yarn stops the lower yarn feeder 5fd and reciprocates the upper yarn feeder 5fua and the upper yarn feeder 5fub, or stops the upper yarn feeder 5fub and the upper yarn feeder 5fua and lower injection Is converted to reciprocating movement of the yarn feeder 5fd. In the configuration as shown in Fig. 2, when the lower yarn feeder 5fd is stopped, the knitting yarn supplied from the upper side to the yarn guide 10fd of the yarn feeder 5fd interferes with the upper yarn feeders 5fua and 5fub of the reciprocating movement. When relayed by the hook member 14 as shown in Fig. 1, interference can be avoided.

Fig. 3 is a diagram showing the configurations of the yarn feeders 5fua, 5fub, and 5fd used in the present embodiment, respectively, as viewed from above. In each yarn feeder 5fua, 5fub, and 5fd, basically, yarn guides of 10fua, 10fub, and 10fd, guide yarns 18fua, 18fub, and 18fd, are fed upwardly, and guided to the yarn feeder 15fua, 15fub, and 15fd. However, the lower yarn feeder 5fd receives the knitting yarn relayed by the hook member 14 in Fig. 1 as the guide hole 18fd at the time of stop. The yarn feeder 5fua for scanning is provided with an interlocking piece 13 for guiding the knitting yarn upwardly fed to the guide member 18fd of the stationary yarn feeder 5fd to the hook member 14. The interlocking piece 13 is provided with an inclined guide portion 13a and an engaging portion 13b in the guide portion 13a.

Fig. 4 is a left side of the interlocking piece 13 which is provided with a yarn 6fd which is upwardly fed to the guide hole 18fd of the yarn guide 10fd of the lower yarn feeder 5fd stopped at one end of the front needle bed 2f, on the upper yarn feeder 5fua. It is a figure which shows the state immediately before guiding to a direction from upper direction. When the yarn feeder 5fua is used for the yarn feeding, the yarn feeder 5fub shown in FIG. 7 is also used for the feeding of the fine yarns and travels leftward at the same time. However, the yarn feeder 5fub is omitted in the drawing. When the yarn feeder 5fd stops and the yarn feeder 5fua moves to the left, the interlocking piece 13 passes through the position of the guide hole 18fd. The interlocking piece 13 is formed with a guide portion 13a inclined so that the left side approaches the center side of the needle bed gap 3, and the position of the guide hole 18fd corresponds to the middle of the inclination of the guide portion 13a. Therefore, the knitting yarn 6fd upwardly directed to the guide hole 18fd is guided from the needle bed gap 3 to the engaging portion 13b along the inclination of the guide portion 13a by the movement in the relative left direction of the interlocking piece 13 with respect to the guide hole 18fd. do.

FIG. 5 is a view showing the state in which the knitting yarn 6fd shown in FIG. 4 is relayed by the hook member 14 from above. Fig. 5 (a) is a diagram showing a state in which the yarn feeder 5fua for scanning shown in Fig. 4 is moved beyond the position of the hook member 14 on the left end side of the front needle bed 2f while knitting the knitting. . The Yanfeeder 5fub for use also moves along with the Yanfeeder 5fua for injection. The spacing between the yarn feeders 5fua and 5fub is maintained so as to maintain the spacing necessary for the knitting process between the feed yarns 15fua and 15fub. When the yarn feed yarn is converted to the yarn feeder 5fub and the yarn feeders 5fua and 5fub are moved to the left end for the first time, the yarn feeder 5fd stops outside the range shown in Fig. 5, such as the right end side of the front needle bed 2f. The interlocking piece 13 provided on the yarn feeder 5fua engages the upper and lower portions 6fdv of the knitting yarn which is fed from the upper portion to the yarn feeder 5fd and passes through the tip of the hook member 14. As shown in Fig. 1, since the interlocking piece 13 is installed at a position lower than the hook member 14, when the engaging portion 13b moves to the left side from the inclined portion 14a of the tip of the hook member 14, it is higher than the upper and lower portions 6fdv of the combined knitting yarn. The portion of can easily pass over the inclined portion 14a. Following the upper and lower portions 6fdv of the knitting yarn coupled to the engaging portion 13b of the interlocking piece 13, the horizontal portion 6fdh of the knitting yarn is formed in the guide hole 18fd of the yarn guide 10fd of the yarn feeder 5fd shown in Fig. 4 stopped at the right side of the front needle bed 2f. In succession. Since the horizontal portion 6fdh of the knitting yarn passes under the yarn feeders 5fua and 5fub, the interference can be prevented even when the yarn feeders 5fua and 5fub reciprocate to the left and right of the figure.

Fig. 5 (b) is a diagram showing a state in which yarn feeders 5fua and 5fub are driven in the right direction from the vicinity of the hook member 14 to continue knitting of the yarn. The interval between the yarn feeders 5fua and 5fub is changed so that the yarn feeder 15fua of the yarn feeder 5fua for injection is directed to the right side than the yarn feeder 15fub of the yarn feeder 5fub for use. The change of this interval is made similarly to patent document 2. The yarn feeder 5fua for injection starts to move in the right direction, so that the interlocking piece 13 falls in the right direction from the hook member 14. In Fig. 5 (a), the upper and lower portions 6fdv of the knitting yarn engaged with the engaging portion 13b of the interlocking piece 13 are engaged with the hook portion 14b by being caught by the hook portion 14b at the position of the height of the hook member 14. With the right movement of the yarn feeder 5fua, the interlocking piece 13 is separated from the upper and lower portions 6fdv of the knitting yarn, and the knitting yarn fed to the yarn feeder 5fd is relayed by the hook portion 14b of the hook member 14. The horizontal portion 6fdh of the knitting yarn from the hook portion 14b of the hook member 14 to the right side of the front needle bed 2f becomes the lower side of the support 12fua of the yarn feeder 6fua or the interlocking piece 13, as shown in Fig. 1, to avoid interference.

FIG. 6 is a view showing the state of releasing relay by the hook member 14 shown in FIG. Fig. 6 (a) shows that the yarn feeder 5fua and 5fd are hooked at the position of the hook member 14 while the upper yarn feeder 5fua is used for injection, the lower yarn feeder 5fd is used for the addition, and the first yarn is knitted. It is a figure which shows the state moving to the left direction until it passes. The lower yarn feeder 5fd moves to the left side together with the upper yarn feeder 5fua from the rest state shown in Fig. 4 to reach the position of the hook member 14. While the horizontal portion 6fdh of the knitting yarn exists between the hook portion 14b of the hook member 14 and the guide hole 18fd of the yarn guide 10fd of the yarn feeder 5fd, the horizontal portion 6fdh is knitted with a knitted fabric by the left movement of the yarn feeder 5fd. Length decreases. When the engaging portion 13b of the interlocking piece 13 reaches the position of the needle bed gap 3 center side in the hook portion 14b of the hook member 14, the knitting yarn 6fd engaged with the hook portion 14b is also caught by the engaging portion 13b of the interlocking piece 13. As shown in the figure, when the engaging portion 13b of the interlocking piece 13 moves leftward than the hook portion 14b of the hook member 14, the knitting yarn 6fd engaged with the hook portion 14b moves to the engaging portion 13b of the interlocking piece 13.

Fig. 6 (b) is a diagram showing a state in which yarn feeders 5fua and 5fd are driven in the right direction from the vicinity of the hook member 14 to continue knitting of the yarn. The interval between the yarn feeders 5fua and 5fd is changed so that the yarn feeder 15fua of the yarn feeder 5fua for injection is directed to the right side of the yarn feeder 15fd of the yarn feeder 5fd for use. The change of this interval is made similarly to patent document 1. As the yarn feeder 15fua of the yarn feeder 5fua for injection precedes the yarn feeder 15fd of the yarn feeder 5fd for use, the coupling portion 13b of the interlocking piece 13 is also the yarn guide 10fd of the yarn feeder 5fd on the lower side. It falls to the right direction from the position of the guide hole 18fd formed in. The position of the yarn guide 10fd in which the guide hole 18fd is formed is lower than the interlocking piece 13, as shown in FIG. As shown in Fig. 6 (b), the position of the guide hole 18fd is engaged with the engaging portion 13b of the interlocking piece 13 in the knitting yarn 6fd at the center side of the needle bed gap 3 rather than the position of the engaging portion 13b of the interlocking piece 13. The part which has been made is deviated to the center side of the needle bed gap 3 along the inclination of the guide part 13a, and is directed upwards from the guide hole 18fd away from the guide part 13a, and the relay in the hook member 14 can be cancelled | released. Subsequently, the yarn knitting which feeds the scan by the upper yarn feeder 5fua and the yarn by the yarn feeder by the lower yarn feeder 5fd is continued. In the meantime, the upper yarn feeder 5fub stops on the right side of the front needle bed 2f. However, in the positional relationship of this embodiment, even if the yarn feeder 5fub is stopped, the knitting yarn which is upwardly steeped does not cause the interference with the moving yarn feeders 5fua and 5fd.

The start of the relay in the hook member 14 and the release of the relay are performed by interlocking the upper and lower portions 6fdv of the knitting yarn in the interlocking piece 13 as shown in Fig. 5 and passing through the guide hole 17fd of the yarn guide 10fd as shown in Fig. 6. In this case, a latch or the like for opening or closing the hook portion 14b may be provided. When the interlocking piece 13 or the yarn guide 10fd arrives, a latch that opens when the interlocking piece 13 arrives is opened.When relaying, the latch is opened when the interlocking piece 13 arrives, and the upper and lower parts 6fdv of the knitting yarn are started.The hook portion is closed by closing the latch when the interlocking piece 13 falls. Bonding of the upper and lower portions 6fdv of the knitting yarn in 14b can be ensured. The release of the relay can open the latch when the yarn guides 10fd are interlocked, and the upper and lower portions 6fdv of the knitting yarns can be directly supplied from the upper portion to the guide holes 18fd of the yarn guides 10fd without passing through the hook portion 14b.

In the above description, it is assumed that when the yarn knitting is performed by the sock knitting machine 11, the yarn is converted. The coarse yarn is made of a twisted yarn made of elastic fibers such as polyurethane, woolly nylon or the like that has shrunk nylon fibers, and the like to impart elasticity to the knitted fabric. Therefore, when it becomes possible to convert a fine yarn, the knitted fabric can form the part from which elasticity differs. Such a yarn conversion can be used not only in socks but also in various knitted fabrics knitted in gloves and flat knitting machines.

In the sock knitting machine 11, in order to three-dimensionally knit the heel portion, the carriage 7 is equipped with a picker as disclosed in Japanese Patent No. 2779862 as a needle sensitizer. It is possible to continuously increase or decrease the number of knitting needles used for knitting at the knitting stage. The socks which use the picker only for one carriage and knit are made to the shape of the foot at the tiptoe side with the heel part so that the big toe side becomes large even in five toes or toe. Since the left and right can not be combined, it is necessary to organize the left foot and the right foot differently. When the picker is mounted on both the carriage 7f for the front needle bed 2f and the carriage 7b for the rear needle bed 2b, the left and right foot can be knitted with the same socks knitting machine 11. However, the heel portion is divided into the front needle bed 2f and the rear needle bed 2b, and as shown in Fig. 2, on the basis of the difference in the inclination angles of the knitting needles 16f and 16b entering the needle bed gap 3, Fig. 5 (a). , (b), and the passing direction of the steeping port 15 shown in Figs. 6 (a) and 6 (b) needs to be converted from the side closer to the needle bed gap 3 or the far side. The upper yarn feeder 5fub and the lower yarn feeder 5fd are fed with the same fine yarn. For example, the feeder 15fub overtakes the side closer to the center of the needle bed gap 3 than the feeder 15fua, and the feeder 15fd feeds the feeder 15fua. By passing the side farther from the center of the needle bed gap 3, the pickers to be used can be switched to knit the left and right socks respectively.

The upper yarn is able to knit uniform stitches by suppressing the tension fluctuation of the knitting yarn by a simple yarn feeding mechanism compared with the side yarn. By evacuating the running rails 4bu and 4bd on the rear needle bed 2b by the knitting of the knitting yarn, it is possible to increase the variety of knitted fabrics by mitigating restrictions on the use of the yarn feeders 5bu and 5bd. In addition, in the arrangement of the traveling rail 4, when selectively interlocking a plurality of rows of yarn feeders 5 from one support stand 8 rather than up and down, interference with the knitting yarns which are upwardly steep cannot be avoided. When the present invention is applied and the evacuation at the time of stopping is possible, interference can be avoided.

According to the present invention, in a flat knitting machine that supplies a plurality of yarn feeders to the yarn knitting machine from above, the yarn is guided to the yarn feeder which is interrupted by the movement of the carriage when it stops, and the knitting yarn is relayed by the knitting stage. By relaying, the yarn supplied from the upper side is fed to the stopped yarn feeder through a path that does not interfere with the movement of the carriage, so that interference of the knitting yarn and the moving portion passing up and down can be avoided even in the upper yarn. When relaying the knitting yarn and selectively interlocking the stopped yarn feeder by the carriage, it moves to the other end side of the moving range to cancel the knitting of the knitting yarn, and the yarn feeder directly supplies the knitting yarn from the upper side. Tension fluctuations that are problematic can be avoided.

Further, according to the present invention, the plurality of yarn feeders of the flat knitting machine can be selectively interlocked by a carriage reciprocating in the longitudinal direction of the needle bed. When the selected yarn feeder moves together with the carriage, there is a case where interference occurs in the knitting yarn which is suddenly radiated upward from the yarn feeder. When stopping the yarn feeder that interferes with the knitting yarn by the carriage movement, one side or the middle of the carriage movement range, the yarn supplied from above to the yarn feeder to be stopped is guided by the guide member to the other end side of the movement range. do. On the other end side, a relay member is provided which relays the knitting yarn supplied from the upper side to the yarn feeder which stops through the path which does not interfere with the carriage movement. Can be avoided. When the stationary yarn feeder is selectively interlocked by a carriage, the knitting of the knitting yarn at the relay member is canceled, and the yarn feeder is directly supplied with the knitting yarn from above, so that the fluctuation in tension can be avoided.

According to the present invention, the guide member guides the knitting yarn supplied from above to the yarn feeder to be stopped, and the knitting yarn is hooked to the hook of the relay member so that the relay can be easily started. When releasing the relay of the knitting yarn supplied to the stopped yarn feeder, the knitting yarn can be easily removed from the hook by passing the yarn feeder stopped to the side of the hook.

Further, according to the present invention, the relay member relays the knitting yarn supplied to the at least one yarn feeder for the yarn feed, and the guide member is provided in the yarn feeder for the injection feed, so that the yarn feeder for the yarn feed is stopped. Interference with the yarn feeder for injection supply can be prevented, and the knitting formation such as converting a plurality of yarns by using the yarn feeder for other yarn feed can be performed.
