The present invention is provided with a toe on the tiptoe, and partial stitch increase and decrease at the heel part, and overall, a sock of a tubular shape, and a high-knit knitted fabric (編成 布) To a sock knitting machine comprising:

Conventionally, socks 1 as shown in Fig. 4 are knitted in a tubular shape by two knitting machines of a needle bed. Fig. 4A is a diagram showing, for example, a front needle bed, and (b) a knitted fabric portion knitted by the rear needle bed, respectively. By knitting the knitting yarn with the front needle bed and the rear needle bed, a tubular shape in which the knitted fabric portion knitted in the front needle bed and the knitted fabric portion knitted in the rear needle bed are connected at both ends of the knitted width. A knitted fabric of is obtained. The initial knitting of the socks 1 starts from the tip of the first toe portion 2a for the first toe, which corresponds to the thumb of the hand. When knitting is completed to the end of the first toe portion 2a, the knitting of the tip of the second toe portion 2b for the second toe corresponding to the index finger of the hand is started. In the same manner, the third toe portion 2c for the third toe and the fourth toe portion 2d for the fourth toe, respectively, corresponding to the middle finger and the ring finger of the hand, are respectively knitted. When the four toes are knitted, after knitting the cylindrical knitted fabric of the portion where the four toes from the first to the fourth toe are combined, the fifth toe part 2e for the fifth toe corresponding to the little finger of the hand is knitted. When the initial knitting of the tip is started and the knitting of the fifth toe portion is finished, the instep portion 3a and the sole portion 3b where the five toes are combined are knitted in a tubular shape as a whole. Next, only the rear needle bed is knitted the heel portion 3c while nasal shortening both sides of the knitting width, and the heel portion 3d is knitted while both sides of the knitting width are crocheted. When the knitting width returns to the width of the sole portion 3b, the ankle portions 4a and 4b are knitted in a cylindrical shape as a whole. Colored stripes 5a and 5b may be added near the ends of the ankles 4a and 4b. Next to the ankles 4a and 4b, the elastic yarns 6a and 6b into which elastic yarns are inserted are knitted in a cylindrical shape as a whole, and finally, the anti-loosening portions 7a and 7b are knitted.

The main part of the knitted fabric of the socks 1 except for the colored stripes 5a and 5b, the elastic yarns 6a and 6b and the anti-loosening parts 7a and 7b is used for scanning and fine yarns. Organized by invisible fine grains. As the yarn, for example, a high elastic yarn called filament twisted yarn (FTY) or wooly nylon is used. The color stripe portions 5a and 5b are knitted, for example, only with knitting yarns of a different color from scanning. The elastic yarn portions 6a and 6b are knitted by inserting high elastic elastic yarn. The anti-loosening parts 7a and 7b are knitted with anti-loosening yarns, such as hot melt yarns. As the product of the sock 1, the anti-loosening in the anti-loosening portions 7a and 7b is not the final treatment, but a finishing treatment is performed in which the anti-loosening portions 7a and 7b are folded inside and sewn after knitting.

FIG. 5 is a diagram showing the configuration of a dedicated sock knitting machine 10 that knits sock 1 as shown in FIG. In the sock knitting machine 10, needle selection drums 11a and 11b are installed on the front needle bed 12a and the rear needle bed 12b, respectively, and used to knit the socks 1 as a cylindrical knit fabric in the needle bed gap 13 Choose a needle to say. The needle selection drums 11a and 11b select pins by raising a pin on a drum body, for example, as an orgel (see Patent Document 1, for example). Above the needle bed gap 13, two rows of two moving rails 14au, 14ad, 14bu and 14bd are hypothesized in parallel with the longitudinal direction of the front needle bed 12a and the rear needle bed 12b, respectively. A yarn feeder is reciprocally supported on each moving rail. Two yarn feeders 15au1 and 15au2 are supported by the moving rail 14au of the upper end on the front needle bed 12a side. The yarn feeders 15ad, 15bu, and 15bd are supported by the movable rails 14ad on the lower end of the front needle bed 12a side and the upper and lower movable rails 14bu and 14bd on the rear needle bed 12b side, respectively. Yarn feeders 15ad, 15bu, and 15bd are supplied with anti-loosening yarns, elastic yarns, and yarns as knitting yarns 16ad, 16bu, 16bd from above. The front needle bed 12a and the rear needle bed 12b are provided with carriages 17a and 17b, respectively, and are reciprocated in the longitudinal direction by interlocking. Each yarn feeder 15au1, 15au2, 15ad, 15bu, 15bd is selectively interlocked by an interlocking pin 19 protruding from the support stands 18a, 18b installed upright on the carriages 17a, 17b. Reciprocating along 17b.

The yarns 16au1 and 16au2 which are suddenly thrown upwards to the yarn feeders 15au1 and 15au2 are injection and fine yarn, respectively. The yarn steeping position for the knitting needles advancing into the needle bed gap 13 from the yarn feeders 15au1 and 15au2 is carried out in advance of the carriage 17a so that the scanning yarn 16au1 is kept at a constant distance from the knitting yarn 16au2 which is a fine yarn. The moving state is switched in accordance with the moving direction (see Patent Document 2, for example). In addition, a yarn feeder for injection feeding and a yarn feeder for coarse feeding may be installed on different moving rails (see, for example, Patent Document 3). The need to change state is the same.

When the feeder yarn feeder 15au1 overtakes the feed yarn feeder yarn feeder 15au2, the lower feeder port in the needle bed gap 13 passes through the position where the needle feeder 12a is removed. Each carriage 17a, 17b is equipped with cams 20a, 20b for driving the knitting needles selected by the needle selection drums 11a, 11b to perform knitting operations, respectively. A picker 21 is also mounted on the carriage 17b on the rear needle bed 12b side. The picker 21 is arranged by sequentially cutting both sides of the knitting needle selected by the needle selection drum 11b from both sides in the longitudinal direction of the rear needle bed 12b and then sequentially knitting them (see, for example, Patent Document 4). ), And is used to knit the heel portions 3c and 3d shown in Fig. 4B. The initial knitting of the big toe part 2a and the like shown in Fig. 4 is performed while supporting or cutting the end of the yarn by the movable looper 22 (see Patent Document 5, for example). A fixed looper 23 is also provided at one end in the longitudinal direction of the front needle bed 12a and the rear needle bed 12b to support the anti-loosening yarns and the knitting yarns 16ad and 16bd as the color threads, respectively, and can be cut by the cutter 24 (for example). See, for example, Patent Document 6).

FIG. 6 is a diagram showing a schematic configuration of the knitting needle 30 arranged side by side on the front needle bed 12a and the rear needle bed 12b of FIG. In the knitting needle 30, the needle 31 and the jack 32 are integrally connected. The needle 31 is provided with the hook 33 at the front-end | tip, and can open and close the opening part of the hook 33 by the latch 34. As shown in FIG. The needle 31 is provided with a stop butt 36 together with a needle butt 35 acting on the cams 20a and 20b mounted on the carriages 17a and 17b of FIG. Jack 32 is also formed on jack 32 which is acted upon by cams 20a and 20b. Each knitting needle 30 is accommodated in a needle groove formed along the longitudinal direction of the front needle bed 12a and the rear needle bed 12b, respectively, and the needle butt 35 and the jack butt are formed by needles by the needle selection drums 11a and 11b. 37 projects from the needle groove so as to receive the action of the cams 20a and 20b. The nose reduction by the picker 21 is made by advancing the selected knitting needle 30 to the needle bed gap 13 side, so that the needle butt 35 and the jack butt 37 are released from the position under the action of the knitting motions by the cams 20a and 20b. The stop butt 36 is formed so that the stitches engaged with the knitting needle 30 are not subjected to the action of a sinker when the knitting needle 30 advances to the needle bed gap 13 by the nose shortening by the picker 21. In the sock knitting machine 10, a cam for driving the sinker is also mounted on the carriages 17a and 17b to press the stitches coupled to the knitting needles 30. Stitches coupled to the knitting needles 30 which are stopped by the pruning by the picker 21 are repeatedly pressed by the sinker, so that cutting or the like may occur. By forming the stop butt 36 at the position where the sinker acts in the stationary knitting needle 30, the stitches to which the stationary knitting needle 30 is engaged can be evacuated above the range where the sinker acts, thereby avoiding repeated pressure. .

However, in the state in which yarns 16au1 and 16au2 which are injected and added to yarn needle 30, which is the object of nose shortening by picker 21, are suddenly fed, knitting yarns 16au1 and 16au2 are applied to the side of stop butt 36. In the heel portions 3c and 3d of the knitting yarn, there is a knitting yarn 16au2 attached to the upper portion of the knitting yarn 16au1 to be injected, but in the knitting needle 30 which has entered the needle bed gap by the picker 21, the knitting yarn 16au1 is stopped butt 36 It takes 16au2, and the knitting yarn 16au2 which is a fine yarn is thinner than the knitting yarn 16au2 which is injected, and it goes off to the side. When the yarn feeders 15au1 and 15au2 switch the moving direction, it is necessary to overtake the yarn feeder so that the yarn feeding yarn for injection feeding use precedes the yarn feeding yarn for coarse yarn feeding, as shown in Patent Documents 2 and 3. The direction of overtaking should fit the positional relationship of the knitting yarns 16au1 and 16au2 in the stop butt 36.

As shown in Fig. 4, the sock 1 having five toes may be considered to be a modified shape of the glove. A glove knitting machine for knitting a glove exclusively is also basically realized in the same configuration as the sock knitting machine 10 shown in FIG. A knitting machine such as the sock knitting machine 10 shown in FIG. 5 cannot be knitted other than the knitting fabric patterns set in the needle selection drums 11a and 11b. In order to knit a knitted fabric of another knitted fabric pattern, it is necessary to mechanically change the pin setting of the drum. In addition, it is difficult to change the operating range of the movable looper 22 and the positions of the fixed looper 23 and the cutter 24 once it is set. Therefore, in order to efficiently operate the hosiery knitting machine 10 or the glove knitting machine with needle needle drums 11a and 11b as shown in Fig. 5, it is necessary to knit the same socks 1 continuously in the set state. There is.

However, the heel portion 3c, 3d like the sock 1 is unnecessary for the glove, so that the same fabric can be formed on the palm side and the back of the hand of the glove. Therefore, when two identical knitted fabrics are knitted, the left and right sides of the glove are prepared. However, in socks 1, heels 3c and 3d are needed on the sole side. Since the picker 21 is required for the knitting of the heel portions 3c and 3d, if the picker 21 is arranged on the rear needle bed 12b side as shown in Fig. 5, the rear needle bed 12b is the sole side and the front needle bed 12a is the instep. The knitted fabric on the side is knitted exclusively, and in this arrangement, the socks 1 are only for the right foot. In order to knit the left foot socks, the pin selections of the needle selection drums 11a and 11b should be reversed from left to right, and the arrangement of the movable looper 22, the fixed looper 23, and the cutter 24 should be reversed. Since the knitting of the left and right socks by one sock knitting machine 10 while making such a setting decreases productivity, for example, the first toe part is knitted on the right side of the needle bed, and the toe part is sequentially arranged on the left side. The order is common, and the settings of the needle selection drums 11a and 11b are common, and the right foot for mounting the picker 21 on the carriage 17b for knitting the heel portion on the rear needle bed 12b, and the heel portion on the front needle bed 12a. In order to do this, two sock knitting machines 10 for the left foot having the picker 21 mounted on the carriage 17a are used.

When the picker 21 of Fig. 5 is also mounted on the carriage 17a on the front needle bed 12a, the sole side is knitted on the front needle bed 12a, and the pin arrangement of the needle selection drums 11a and 11b, the movable looper 22, the fixed looper 23 and the cutter The arrangement of 24 is theoretically thought to be possible to knit a left foot sock without changing from the setting state for the right foot. However, since the knitting needle 30 which advances to the needle bed gap side by the picker 21 becomes the front needle bed 12a side, the positional relationship between the knitting yarns 16au1 and 16au2 applied to the stop butt 36 is reversed, and the rear needle bed 12b In the overtaking relationship suitable for stopping the side stitch 30 on the side, an intersection occurs between the injection and the superfine. Since the intersections are formed at positions away from the knitting widths of the heel portions 3c and 3d, when the knitting yarns 16au1 and 16au2 including the intersection portions are supplied in the subsequent knitting course, the intersection portions are among the knitted fabrics knitted as the heel portions 3c and 3d. It is formed and the appearance is damaged.

An object of the present invention is to provide a sock knitting machine that can equally knit left and right socks by one sock knitting machine and can easily convert left and right.

The present invention selects knitting needles installed side by side on a pair of flat needle beds facing each other in a mountain shape with needle bed gaps interposed therebetween according to a pattern preset in the needle selection drum.

(Example)

Hereinafter, the technical matters related to the socks knitting machine 40 as an example of embodiment of this invention are demonstrated with reference to FIGS. In the following description, parts corresponding to those described above are given the same reference numerals, and redundant descriptions are omitted.

1 is a diagram showing a schematic configuration of a sock knitting machine 40 of the present embodiment. In the sock knitting machine 40, the picker 41 is mounted in the carriage 17a on the front needle bed 12a side based on the sock knitting machine 10 shown in FIG. As described above, simply installing the picker 41 on the front needle bed 12a may damage the heel portions 3c and 3d touched on the front needle bed 12a. Not only are the yarn feeders 15au1 for scanning and the yarn feeder 15au2 for additives assigned to the upper end of the moving rails 14au and 14ad of the stage, but also the yarn feeder 15ad for additives assigned to the lower end. The newly assigned yarn feeder 15ad is set such that the positional relationship of the trajectory through which the yarn feeder is overtaken by the yarn feeder of yarn feeder 15au1 for scanning is different from that of yarn feeder 15au2 for yarn feeder.

In the case of using the additionally-adjusted yarn feeders 15au2 and 15ad for the right foot and the left foot, the unused side should be stopped to support the end of the thread. For this reason, in addition to the fixed looper 42 like the fixed looper 23 shown in Fig. 5, a fixed looper 43 serving as an additive knitting end support device is provided. However, since the knitting yarn and the yarn are different at the timing of catching the knitting yarn which becomes the knitting yarn or the yarn from the knitting fabric to the yarn feeder of the yarn feeder and supporting the end of the yarn, the cutter 44 for both fixed loopers 42 and 43 Even when using a common, the cutting can be performed separately according to different timing. With regard to the assignment of the yarn feeder, in Fig. 5, the yarn feeder 15ad, which is used for anti-loosening, is used as a sharp yarn feed, so that the pickers 21 and 41 are converted to the heel of either the rear needle bed 12b or the front needle bed 12a. Parts 3c and 3d can be organized.

That is, in the case where the yarn feeder 15ad is used as the steep feed, the overtaking trajectory of the yarn feeder of the yarn feeder 15ad with respect to the yarn feeder of the yarn feeder 15au1 for injection, and the yarn feeder 15au2 with respect to the yarn feeder of the yarn feeder 15au1 is used. It should be the opposite of the dune overtaking trajectory. When the needle needle 30 of the front needle bed 12a is raised by the picker 41 of the front needle bed 12a side, and the nose needle is reduced by raising the needle needle 30 of the rear needle bed 12b by the picker 21 of the rear needle bed 12b side. In this case, the positional relationship between the knitting yarn 16au1 to be scanned and the knitting yarn 16ad to be added at the stop butt 36 is reversed from left to right. As a result, in order not to create an intersection when switching the movement directions of the yarn feeders 15au1 and 15ad, the yarn feeder of the yarn feeder 15au1 for injection is viewed from the front of the knitting machine 15ad, for example, from the front of the knitting machine. The passing trajectory must be overtaken. In the case of the additive-use yarn feeder 15au2 supported by the moving rail 14au which is the same as the yarn feeder 15au1 for injection, the two additive-use yarn feeders 15au2 and 15ad can be used to make the passing trace passing from the front of the knitting machine to the front side of the person watching. The trajectory at the time of overtaking the injection yan feeder 15au1 is reversed. Thus, by using the beaker 21 on the rear needle bed 12b and the yarn feeder 15au2 as the additive, the socks 1 for the right foot were knitted as shown in Fig. 4, and the yarn as the picker 49 on the front needle bed 12a. The feeder 15ad can be used to knit socks for the left foot.

Fig. 2 is a diagram showing the right foot sock 1 that can be knitted by the sock knitting machine 40 of Fig. 1 in (a) and the left foot sock 51 in (b), respectively. The sock 1 shown in (a) knits the instep part 3a and the ankle part 4a of the front side by the front needle bed 12a, and the heel parts 3c and 3d are knitted by the back needle bed 12b. In the socks 51 shown in (b), the instep portion 53a and the ankle portion 4a on the front side are knitted by the rear needle bed 12b, and the heel portions 3c and 3d are knitted by the front needle bed 12a. The instep portion 53a of the sock 51 is basically the same as the sole portion 3b of the sock 1, as shown in Fig. 4B. The sole portion of the sock 51 in the relationship between the instep 53a and the front and back is basically the same as the instep 3a of the sock 1. Except for the heel portions 3c and 3d, the socks 1 shown in (a) and the socks 51 shown in (b) have a relationship between the front and back, and the settings of the needle selection drums 11a and 11b can be used in common.

Also, in the sock knitting machine 40 of Fig. 1, the picker 41 is also provided on the front needle bed 12a side together with the picker 21 on the rear needle bed 12b side, so that the heel 1 part 3c, 3d is formed by the front needle bed 12a and the rear needle bed 12b. Each may be knitted to form heel portions 3c and 3d on both sides of the same sock having five toes. In this way, the socks forming the heel portions 3c and 3d on both sides can be used for both the right foot and the left foot even if there are five toe portions.

Fig. 3 shows the yarn 16adv which is suddenly steeped from upper yarn to yarn feeder 15ad when the yarn feeder 15ad is stopped on the moving rail 14ad which is different from the moving rail 14au on which the scan feeder 15au1 reciprocates. It is a figure which shows the method of evacuating so that it may not interfere with yan feeder 15au1. In each of the yarn feeders 15au1 and 15ad, the feeder rods 46au1 and 46ad are provided so as to hang from the supports 45au1 and 45ad which are supported by the moving rails 14au and 14ad and are slidably displaced. Feeder holes 47au1 and 47ad are respectively installed at the lower ends of the supply rods 46au1 and 46ad. Each support 45au1, 45ad is provided with yarn guides 48au1 and 48ad which receive the knitting yarns which are upper yarns and relay them to the yarn feed ports 47au1 and 47ad, respectively. When the yarn feeder 15ad stops, the upper and lower portions 16adv of the knitting yarn 16ad interfering with the yarn feeder 15au1 are portions upwardly from the yarn guide 48ad as indicated by the two-dot chain lines.

An interlocking piece 49 serving as a guide member is attached to the support 45au1 of the upper yarn feeder 15au1. In addition, when the lower yarn feeder 15ad is stopped at one end side or halfway of the moving rail 14ad, the hook member 50 which is a relay member is provided in the other end side of the moving rail 14ad. The height of the interlocking piece 49 is lower than the hook member 50. Yarn yarns fed from the yarn feed openings 47au1 and 47ad at the tips of the yarn feeders 15au1 and 15ad are connected to a stitch loop in the knitted fabric or temporarily supported by a looper or the like.

At the start of the stop of the feeder 15ad, as shown by the two-dot chain line, the upper and lower portions 16adv of the knitting yarn are in a position where interference occurs due to the movement of the upper feeder 15au1. The interlocking piece 49 can guide the upper and lower portions 16adv of the knitting yarn to be coupled to the hook member 50 as indicated by the solid line when the yarn feeder 15au1 moves to the left through the broken line. The knitting yarn between the hook member 50 and the yarn guide 48ad of the stopped yarn feeder 15ad becomes a horizontal portion 16adh, and does not interfere with the reciprocating yarn feeder 15au1. When the yarn feeder 15ad is changed from the stationary state to the use state, the yarn feeder 15ad is once moved to the position of the hook member 50 to release the knitting and used in the state of upper yarn.

In addition, when yarn feeder 15ad for reciprocating the moving rail 14ad is used for the feeding of the fine yarn, the anti-loosening yarn used in the sock knitting machine 1 as shown in Fig. 4 cannot be used. However, since the socks 1 and 51 are finished after knitting to fold the anti-loosening portions 7a and 7b inwards, the anti-loosening is also temporary. For example, the socks can be effectively prevented by using only fine yarn.

According to the present invention, a picker capable of increasing or decreasing the stitching for the heel portion is provided on both carriages of a pair of flat needle beds facing each other in a mountain shape with needle bed gaps interposed therebetween, and a needle feeder for injection. Since the additional yarn feeder can be selected to be suitable for the operation of the picker, the knitting fabric of the left and right socks can be equally knitted by one sock knitting machine. The right and left conversion can be easily performed with respect to the picker and the yarn feeder of the additive. The knitting conditions can be equalized from left to right since the same sock knitting machine organizes the left and right socks.

According to the present invention, three yarn feeders, an injection yarn feeder and two additive yarn feeders, can be reciprocally supported by two moving rails. Since the two additive yarn feeders are supported by different moving rails, the overtaking trajectory for the injection yarn feeder can be easily realized.

Moreover, according to this invention, since the scanning yarn feeder and the additive yarn feeder are supported above and below the moving rail of the upper and lower sides, it is possible to perform the yarn knitting as described in Patent Document 2. In addition, since the feed yarn feeder is supported by the downward moving rail, the feed yarn formation can be performed as described in Patent Document 3.

According to the present invention, the yarn yarn fed from the yarn feeder supported by the third moving rail and the yarn yarn fed from the yarn feeder yarn stopped without being used for the yarn knitting are the yarn knitting yarn end support mechanism and the yarn use. Since the knitting end portion supporting mechanism can be separately supported and released, the support and release of the end of the yarn during the conversion of the yarn can be smoothly performed.
