Abstract

A weft knitting machine capable of inserting a warp which is a weft knitting machine that feeds a warp to a knitting needle only from a needle bed on one side, and which can knit a fabric by using a warp even with a knitting needle from a needle bed on the other side without requiring an extra yarn guide. A knitting method in such a weft knitting machine is also provided. When the hooks (19) of five knitting needles (17) are made to advance from a rear needle bed (23) to between the knitting needles (16a, 16b) of a front needle bed (22), a purl can be knitted by these five knitting needles (17). The knitting needles (16a, 16b) may not be made to advance from the front needle bed (22) to a tip part (20) one by one. Alternatively, a texture such as rib and links can be knitted using a knitting yarn which is fed as a warp by making the knitting needle (16) advance from the front needle bed (22) to the advancing range of the knitting needle (17) from the rear needle bed (23).

Description

Flat knitting machine capable of inserting warp and knitting method using the flat knitting machine

Technical field

[0001] The present invention provides a warp that also has a function of knitting a knitted fabric by supplying a knitting yarn that can be a warp from a lace bar that is not a knitting force of a knitted fabric using a basic weft as a knitting yarn. The present invention relates to an insertable flat knitting machine and a knitting method using the flat knitting machine.

Background art

Conventionally, it has been known that a structure similar to warp knitting can be knitted by using a flat knitting machine 1 as shown in FIG. 10 (see, for example, Japanese Patent No. 3452639). In the flat knitting machine 1, a pair of front and rear needle beds of the front needle bed 2 and the rear needle bed 3 are opposed to each other with the mouth 4 interposed therebetween. A warp insertion mechanism 5 is provided above the mouth opening 4. A plurality of knitting needles 6 and 7 are arranged side by side on the front needle bed 2 and the rear needle bed 3, respectively. The warp insertion mechanism 5 can feed a knitting yarn that can be a warp to a hook at the tip of the knitting needle 6 that advances from the front needle bed 2 to the tooth opening 4. The front needle bed 2 and the rear needle bed 3 have carriages 8 and 9 mounted with a force mechanism for selectively advancing and retracting a plurality of knitting needles 6 and 7 with respect to the tooth opening 4 perpendicular to the paper surface. It is installed so that it can travel in both directions. Above the mouth 4, a yarn feeder 10 is supported by a yarn path rail 11 so as to be able to reciprocate in a direction perpendicular to the paper surface. A plurality of yarn path rails 11, three in FIG. 10, are installed above the tooth opening 4 in a direction perpendicular to the paper surface. Each yarn path rail 11 is formed with a track for moving the yarn feeder 10 on both sides. The carriages 8 and 9 can be selected and taken along with one of the yarn feeders 10. The yarn feeder 10 feeds the knitting yarn to the knitting needles 6 and 7 that advance into the tooth mouth 4. When the carriages 8 and 9 take the yarn feeder 10 and the knitting needles 6 and 7 are driven by the cam mechanism, a basic weft knitted fabric can be obtained as the flat knitting machine 1.

The warp insertion mechanism 5 is capable of swinging motion about the swing shaft 12 and reciprocating motion along the swing shaft 12. The warp insertion mechanism 5 includes a plurality of race bars 13. A plurality of yarn feeding pipes 14 can be attached to each race bar 13. Each yarn supply pipe 14 can supply knitting yarn to the hook at the tip of the knitting needle 6 that advances from the front needle bed 2 to the tooth opening 4. Duplicate The yarn feeding pipes 14 are arranged at intervals in a direction perpendicular to the paper surface. In the warp insertion mechanism 5 shown in the figure, four rows of yarn feeding pipes 14 can be provided. When the warp insertion mechanism 5 swings around the swing axis 12, the tip of the yarn supply pipe 14 performs a swing motion across the tooth opening 4. When the warp insertion mechanism 5 reciprocates along the swing axis 12, the tip of the yarn supply pipe 14 performs a lapping operation along the longitudinal direction of the tooth mouth 4. When the yarn feeding pipe 14 is combined with the knitting needle 6 in a swing operation and a wrapping operation, a structure similar to warp knitting can be knitted. However, when the knitting yarn is fed to the plurality of knitting needles 6 by the lapping operation, the weft knitting structure is knitted by the intermediate knitting needles 6. The swing operation and the lapping operation are performed in a state where the carriages 8, 9 and the yarn feeder 10 are stopped at a position where the force of the yarn supplying pipe 14 is also separated in the direction perpendicular to the paper surface.

The warp insertion mechanism 5 is used not only for the purpose of knitting a structure similar to warp knitting but also for the purpose of knitting a weft knitting structure (for example, JP-A-8-74146). See Fig. 16 of JP-A-8-74146. In Fig. 10 of the present application, in Fig. 10 of the present application, the knitting yarn supplied from the yarn feeder 10 and the knitting yarn supplied from the yarn supply pipe 14 are used in combination. An example of partial plating organization is shown. In FIG. 17 of Japanese Patent Application Laid-Open No. 8-74146, by utilizing the fact that a large number of yarn supply pipes 14 can be mounted on the race bar 13 at relatively narrow intervals, a band-shaped handle having a relatively narrow width is formed. An example of organizing is shown! FIG. 1 of Japanese Patent Laid-Open No. 8-74146 shows the cam arrangement in the front-side carriage corresponding to the carriage 8 for the front needle bed 2 shown in FIG. 10 of the present application. Three cam systems are mounted on the front carriage. The center is a cam lock for wefts having knitting and transfer functions. Both sides are cam locks for warp for knitting the knitting yarn fed from the warp insertion mechanism 5.

In the weft knitting machine 1 into which the warp can be inserted as shown in FIG. 10, the weft knitting structure can be knitted as described above by using the knitting yarn fed from the yarn feeding pipe 14 of the warp insertion mechanism 5. However, the flat knitting machine 1 is designed to supply yarn only to the knitting needle 6 of the front needle bed 2 on one side from the warp insertion mechanism 5. In the specifications of the flat knitting machine 1, the knitting needle 7 of the rear needle bed 3 on the other side from the yarn feeding pipe 14 is not fed, and the carriage 9 is also fed from the yarn feeding pipe 14. A cam lock for warp adapted to perform knitting using knitting yarn is installed. . On the left side of Fig. 10, for example, on the left side of Fig. 10, there is a possibility that the knitting yarn will be fed to the hook of the knitting needle 7 that advances from the back needle bed 3 to the mouth 4 by swinging and lapping operations. This is because the yarn cannot be fed stably as a whole.

It is also conceivable to guide the knitting yarn fed from the yarn feeding pipe 14 to the hook of the knitting needle 7 on the rear needle bed 3 with a special guide device or the like provided separately. However, if such a guide device or the like is provided, the configuration of the flat knitting machine 1 becomes complicated, and the number of usable yarn feeders 10 and yarn supply pipes 14 may be limited.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a flat knitting machine 21 that can feed warp 15 only to knitting needle 16 on front needle bed 22 and warp 15 on knitting needle 17 on rear needle bed 23 as an embodiment of the present invention. The basic concept that enables the knitted fabric to be knitted is shown. As described above, the warp 15 is not necessarily a knitting yarn used for knitting a warp knitting structure, but is shown as “warp” for convenience. The warp yarn 15 is fed so as to be hooked on the needle stem on the proximal end side relative to the hook 18 of the knitting needle 16 of the front needle bed 22. The knitting needles 16 on the front needle bed 22 on which the warp yarn 15 is applied are selected at intervals. Between the knitting needles 16, hooks 19 of the knitting needles 17 on the rear needle bed 23 advance. The tooth opening 20 in which the hooks 18 and 19 advance is formed as a gap in which the front needle bed 22 and the rear needle bed 23 of the flat knitting machine 21 face each other. With the yarn feeder 10 as shown in FIG. 10, the knitting yarn can be fed to the knitting needle that advances from any of the front and back needle beds. However, since the warp 15 is fed by combining the swing operation and the lapping operation of the yarn feeding pipe 24, the knitting needle 17 from the rear needle bed 23 cannot be stably fed. Since the warp 15 can be stably fed from the yarn feed pipe 24 to the needle stem of the knitting needle 16 on the front needle bed 22, it is possible to reliably carry the warp 15 between the knitting needles 16. . Furthermore, if the warp 15 is passed over the knitting needle 16 from the front needle bed 22 at the tooth opening 20, the hook 19 of the knitting needle 17 is advanced from the rear needle bed 23, the warp 15 is hooked on the hook 19, and the knitting needle 17 Can be pulled into the back needle bed 23 to form a stitch loop. In the knitting needle 16 for passing the warp 15, the start side is a knitting needle 16 a and the end side connected to the yarn feeding pipe 24 is a knitting needle 16 b.

As shown in the figure, the back needle bed 23 is located between the knitting needles 16a and 16b that advance from the front needle bed 22 to the tooth opening 20. If the hooks 19 of the five knitting needles 17 are advanced, the back stitch can be knitted with these five knitting needles 17. The number of knitting needles 16a and 16b to be advanced from the front needle bed 22 to the tooth mouth 20 is not necessarily one by one. The warp yarn 15 can be stretched over the knitting needles 16a and 16b of the front needle bed 22 which is the boundary between the area where the front stitch is knitted with the plurality of knitting needles 16 and the area where the back stitch is knitted with the plurality of knitting needles 17. . In the figure, ribs and links that use the knitting needles 16 and 17 from the front and back needle beds by moving the knitting needle 16 from the front needle bed 22 into the range where the knitting needle 17 from the rear needle bed 23 has advanced. Such a structure can be knitted using a knitting yarn fed as a warp. In the flat knitting machine 21, the cam mechanism mounted on the carriage that runs along the needle bed drives the advance / retreat operation of the knitting needles 16, 17, so that the knitting needles 16, 17 as shown in the figure advance into the tooth opening 20. It will not keep state. In the figure, the knitting needle 16a is advanced and driven forward and backward to the tooth opening 20, the five knitting needles 17 are advanced and retracted to the tooth opening 20 while sequentially shifting the phase, and finally the knitting needle 16b is driven to advance and retract to the tooth opening 20. The

2, 3, 4, and 5 show a schematic procedure for knitting using the warp 15 with the knitting needle 17 of the back needle bed 23 as shown in FIG. 1. FIG. 2 shows a state in which the warp 15 is pulled out to the lower side of the path in which the knitting needle 16a of the front needle bed 22 advances and retreats to the tooth opening 20 by a swing operation in which the yarn feeding pipe 24 is moved away from the tooth opening 20. Fig. 3 shows a swinging motion in which the yarn feeding pipe 24 is swung upwardly toward the mouth 20 and the warp 15 is hung from the lower side to the upper side of the needle stem of the knitting needle 16a of the front needle bed 22 that advances into the mouth 20. Indicates the state. Fig. 4 shows a wrapping operation in which the yarn feeding pipe 24 is moved to the back side of the paper surface and a swinging motion in which the yarn feeding pipe 24 is swung away from the tooth opening 20, and the warp yarn 15 is transferred to the needle stem of the knitting needle 16b. It shows the state where it is pulled up to the upper part of the rear needle bed 23 after being hung on the back. FIG. 5 shows a state in which the hook 19 of the knitting needle 17 is advanced from the rear needle bed 23 to the tooth opening 20. As shown in FIG. 10, the yarn supply pipes 24 can be provided in a plurality of rows, for example, four rows, but in FIG. 2 to FIG. 5, only one row is shown for convenience. The knitting needles 16 and 17 are flat needles, and transfer blades 25 are mounted on one side surface. The hooks 18 and 19 at the tips of the knitting needles 16 and 17 can be opened and closed by the blades 26 and 27. The knitting needles 16, 17 are erected on the front needle bed 22 and the rear needle bed 23, respectively, at a fixed pitch-the needle groove formed between the one dollar plates 28, 29 moves forward and backward with respect to the tooth opening 20. Accomodated as possible. Near the tip of the front needle bed 22 and rear needle bed 23 facing the tooth opening 20, wires 30, 31 such as piano wires are perpendicular to the paper surface. It is provided so as to penetrate in the direction. The wires 30, 31 substantially function as the leading edge of the front needle bed 22 and the rear needle bed 23 on the side of the mouth 20 but, in the flat knitting machine 21, the front needle bed 22 and the rear needle bed 23 Supported by fixed thin forces 32 and 33, respectively.

As the knitting needles 16 and 17, compound needles that can be moved forward and backward separately by separating the needle main body and the slider with a labyrinth force can be used. If you use a compound needle that divides the tip of the tip into two parts and sandwiches both sides of the hook of the needle body as the slider, you can move the slider to the tooth opening 20 and transfer it. Do not use the blade 25.

FIG. 6 shows a state in which the swing operation of swinging above the tooth opening 20 is performed for all four rows of yarn supply pipes. The swing operation is performed by swinging and displacing the warp insertion mechanism 35 around a swing shaft 34 perpendicular to the paper surface. Although FIGS. 2 to 5 show only the yarn supply pipe 24, the yarn supply pipe 24 is the yarn supply pipe farthest from the front needle bed 22 in the four rows. The yarn feed pipe closest to the front needle bed 22 in the four rows is designated as the yarn feed pipe 36. Each row of yarn feeders is attached to race bar 37. The race bar 37 can be swung around the swing shaft 34 of the warp insertion mechanism 35, and this swing displacement is driven by the swing mechanism 38. When the race bar 37 is driven to swing by the swing mechanism 38, the tip of each yarn supply pipe is positioned above the tooth opening 20 and at a position where it moves away from the tooth opening 20 on the rear needle bed 23. Swing movement is performed by swinging between the two. However, even if the yarn feeding pipe 24 is swung above the tooth opening 20, the warp 15 cannot be drawn below the knitting needle 17 that advances from the rear needle bed 23 to the tooth opening 20. That is, the state corresponding to FIGS. 2 and 4 cannot be realized for the knitting needle 17 from the rear needle bed 23. Therefore, in this embodiment, as shown in FIGS. 2 to 4, the warp yarn 15 is hung on the needle stem of the knitting needle 16 that advances from the front needle bed 22 to the tooth opening 20. Needless to say, the yarn feeder 39 can supply knitting yarns serving as wefts to the respective knitting needles 16 and 17.

FIG. 7 shows a simplified configuration of the cam mechanism 40 that enables the warp 15 to be knitted with the knitting needles 17 of the back needle bed 23. The cam mechanism 40 is separately mounted on a carriage on the front needle bed 22 side and a carriage on the rear needle bed 23 side. Each carriage is equipped with three cam systems. In the center, the knitting 'transfer cams 41F and 41B are located on the front needle bed 22 side and the rear needle bed 23 side. Each is provided. Hereinafter, “F” indicates the front needle bed 22 side, and “B” indicates the rear needle bed 23 side. The knitting and transfer cams 41F and 41B are formed for the purpose of enabling the knitting operation and the transfer operation with the wefts fed from the yarn feeder 39 of FIG. Each carriage is provided with warp cams 42F and 42B; 43F and 43B on both sides of the knitting and transfer cams 41F and 41B, respectively. The warp cams 42F and 42B are on the leading side when the carriage travels to the left, and the warp cams 43F and 43B are on the trailing side. When the carriage travels to the right, the warp cams 43F and 43B are on the leading side, and the warp cams 42F and 42B are on the trailing side. In the carriage for the front needle bed 22 and the rear needle bed 23, It is also possible to take the yarn feeder 39 along with the warp cams 42F, 42B; 43F, 43B. Therefore, knitting using the wefts fed from the yarn feeder 39 using the warp cams 42F, 42B; 43F, 43B is also possible. Also, for example, of the three cam systems, the first force system S1 can be knitted, and the second cam system S2 can be transferred and used. FIG. 8 and FIG. 9 show the configuration of the warp cams 43F and 43B in FIG. 7 and the locus of the knitting needle bat guided by the cams in a simplified manner. FIG. 8 also shows the configuration of the knitting needle 16. The knitting needle 16 is provided with a hook 18 and a blade 26 on the front end side. A needle jack 45 is connected to the rear end side of the knitting needle 16, and the needle jack 45 is provided with a butt 46 protruding above the needle groove. The cam mechanism 40 in FIG. 7 acts on the butt 46 of the needle jack 45. If the knitting needle is a compound needle, a slider cam is also provided. Also on the rear needle bed 23 side, a -1 needle jack is connected to the knitting needle 17 and the bat is driven by a cam. It should be noted that the rear needle bed 23 side is arranged upward and the front needle bed 22 side is arranged downward with the tooth opening 20 in between.

Needle raising cams 50F and 50B, guard cams 51F and 51B, and knitting cams 52F and 52B are provided on the warp cams 43F and 43B. The knitting cams 52F and 52B are provided only on the side close to the knitting / transfer cams 41F and 41B in FIG. A butt passage 53 is provided in the warp cam 43F on the front needle bed 22 side on the side farther from the knitting 'transfer cams 41F and 41B. The bat passage 53 guides the noto 46 from the tack height passage 53a to the plating height passage 53b.

FIG. 8 shows the bat trajectories 54F and 54B when the carriage travels to the left. The The butt locus 54F on the front needle bed 22 side passes between the needle raising cam 50F and the guard cam 51F from the lower side of the knitting cam 52F, becomes the knitted height at the top 50Fa of the needle raising cam 50F, and the tooth mouth 20 side The most advanced to. If the stitch is held on the hook 18 of the knitting needle 16, the spatula 26 is opened and moved to the needle stem side to be cleared. After the top 50Fa, it returns to the tack height. When selecting the tack for the knitting needle 16, the top 50Fa does not act and maintains the tack height. After passing the top 50Fa, the bat 46 enters the tack height passage 53a of the bat passage 53 and is further guided through the plating height passage 53b. Therefore, after the carriage has passed, the knitting needle 16 remains in the tooth opening 20 in a state of advancing to a plating height that is slightly higher than the tack height. On the rear needle bed 23 side, the butt locus 54B of the needle jack is in a submerged state where the needle groove force does not protrude so as to pass without receiving the action of the needle raising cam 50B. Therefore, even after the carriage has passed, the knitting needle 17 does not advance into the tooth opening 20 but keeps being pulled into the rear needle bed 23. The butt passage 53 on the front needle bed 22 side does not have the plating height passage 53b, and the end of the trajectory 54F can be terminated at the tack height.

FIG. 9 shows bat trajectories 55F and 55B when the carriage travels to the right. The butt trajectory 55F on the front needle bed 22 side moves the plating height passage 53b and tack height passage 53a of the butt passage 53 in the opposite direction to FIG. 8, and the top 50Fa of the needle raising cam 50F does not act. Then, the tucking cam 52F is operated while the tack height is maintained, and the knitting needle 16 is pulled into the front metal plate 22. The butt locus 55B on the rear needle bed 23 side is guided by the top 50Ba of the needle raising cam 5OB to advance to the tooth opening 20 up to the knit height, and the knitting needle 17 is inserted into the rear needle bed 23 by the knitting cam 52B.

Also in the warp cams 42F and 42B shown in FIG. 7, the warp 15 can be used for knitting by using the knitting needle 17 on the rear needle bed 23 side in an operation symmetrical to FIGS. Although the knitting needle 16 is advanced from the front needle bed 22 side into the tooth opening 20 and the warp yarn 15 fed from the yarn feeding pipe 24 of the warp insertion mechanism 25 is passed between the knitting needles 16, the front needle The locking member that advances from the floor 22 and hangs the warp 15 is not limited to the knitting needle 16. For example, a member that advances and retreats with respect to the tooth opening 20 such as a yarn guide is provided with a portion for hanging the warp 15 fed from the yarn feeding pipe 24, or a dedicated member that receives and locks the warp 15 is provided. You can also. Also as a knitting needle When a compound needle is used, the path for guiding the slider can be changed so that the warp 15 can be hooked on the slider. If the locking member that advances to the tooth opening 20 does not draw the warp 15 into the front needle bed 22 and releases the warp 15 at the tooth opening 20, only the back stitch by the knitting needle 17 on the back needle bed 23 is removed. It can be organized.

Further, in FIG. 8, the knitting needle 16 on the front needle bed 22 side is advanced to the tooth opening 20 by traveling of the carriage, and then the warp 15 is passed between the knitting needles 16 and the next carriage travels on the side of the rear needle bed 23. The knitting needle 17 is advanced to the tooth opening 20 to retract the force, and the knitting needle 16 on the front needle bed 22 side is also retracted from the tooth opening 20. While moving the carriage, the knitting needle 16 of the front needle bed 22 and the knitting needle 17 of the rear needle bed 23 positioned between them are advanced into the tooth opening 20 by the carriage travel, and then the warp 15 is moved to the front needle bed 2 2 The knitting needles 16 on the front needle bed 22 and the knitting needles 17 on the rear needle bed 23 can be retracted simultaneously from the tooth opening 20 by the next carriage traveling.

In order to enable such a knitting operation, a butt passage 53 similar to the guard cam 51F for the front needle bed 22 is provided in the guard cam 51B for the rear needle bed 23 shown in FIGS. Good. If the butt passage 53 is also provided in the guard cam 51B, the warp cams 42F, 42B; 43F, 43B are symmetrical in the longitudinal direction. If the butt trajectory on the rear needle bed 23 side is also symmetric with the butt trajectories 54F and 55F on the front needle bed 22, the front and rear knitting needles 16 and 17 are simultaneously advanced to the tooth opening 20, and then the warp 15 is The knitting needles 16 and 17 are hung, and the warped yarn 15 can be knitted with the knitting needles 17 of the rear needle bed 23.

As described above, the flat knitting machine 21 into which the warp can be inserted has a pair of needle beds such as the front needle bed 22 and the back needle bed 23 facing each other at the mouth 20 and one needle bed side such as the front needle bed 22 Only has a lace bar 37 capable of supplying a knitting yarn that can be a warp 15, a locking member such as a knitting needle 16, advance drive means such as warp cams 42F and 43F, warp cams 42B and 43B, etc. Including knitting drive means. A plurality of locking members are provided on the needle bed on one side and can advance into the tooth opening 20, and the teeth are provided on both sides of the range where knitting is performed on the other needle bed such as the rear needle bed 23 by the advance driving means. You can advance to mouth 20. The knitting yarn fed from the lace bar 37 can be passed between the locking members that advance into the tooth opening 20. After the knitting yarn is passed between the locking members, the knitting drive means uses the knitting yarn on which the knitting needle 17 is stretched by advancing the needle bed force knitting needle 17 on the other side between the locking members. When driving to knitted fabric, special Even without using a yarn guide device or the like, knitting using the needle bed on the other side can be performed. For example, even if the knitting needle 16 on one side of the needle bed alone cannot be knitted and force-knitted, the back stitch can also be knitted with the knitting needle 17 on the other side of the needle bed.

The present invention can be implemented in various other forms without departing from the spirit or main characteristic power thereof.

Industrial applicability

According to the present invention, the locking member is advanced from the one side needle bed to both sides of the range where knitting is performed on the other side needle bed, and the race bar force is fed between the locking members. It becomes possible to pass the knitting yarn. When the knitting yarn is stretched between the locking members, a special yarn guiding device is driven between the locking members by driving the knitting needle on the other side of the needle bed to retreat. Even without using knitting, knitting using the knitting needles on the other needle bed can be performed. The knitting needle on the other needle bed may be advanced to the tooth opening before the knitting yarn is passed between the locking members, or the force may be advanced to the tooth opening. For example, it is possible to knitting the back stitch with the knitting needles on the other side even if the knitting needles on the one side of the needle bed cannot be used for the front and force knitting.

Further, according to the present invention, the locking member is advanced from the needle bed on one side to the position in the mouth of the mouth that is on both sides of the range where knitting is performed on the needle bed on the other side. The other needle bed force knitting needle is advanced to a position in the mouth that falls within this range. From the lace bar, yarn is fed so that the knitting yarn is passed between the locking members that have advanced to the mouth of the needle bed force on one side. Since the knitted fabric is knitted with the knitting needle that extends from the needle bed on the other side into the tooth opening using the knitting yarn stretched between the locking members, the other side can be used without using a special yarn guide device. Can be knitted using any needle bed.

Further, according to the present invention, after the knitting yarn fed from the race bar is passed between the locking members advanced to the mouth of the one side needle bed force, the knitting needle is fed from the other needle bed between the yarn feeding members. The knitting yarn on the other side of the needle bed and the lace bar force are used for knitting. Knitted fabric can be knitted.

Further, according to the present invention, since the knitting needle on one side of the needle bed is used as the locking member, knitting using the knitting needle on the other side of the needle bed is performed with a basic configuration as a conventional flat knitting machine. Is possible.

Further, according to the present invention, the knitted fabric using the knitting yarn stretched between the locking members is knitted even if the knitting needle on one side of the needle bed is used. Using a knitting needle on the floor, it is possible to knitting a structure such as ribs and links using a knitting yarn fed as a warp.
