Description

  The present invention relates to a flat knitting machine provided with a compound needle as a knitting needle, in which the leading end of a slider for opening and closing the hook is separated into two blades that can advance into the tooth opening from the upper edge of the hook, and a transfer method in the flat knitting machine About.

  Conventionally, as a knitting needle of a flat knitting machine, a composite needle that separates into two blades that allows the leading end of the slider that opens and closes the hook to advance into the tooth opening rather than the upper edge of the hook can be transferred using the slider. The technique to perform is known (for example, refer patent document 1). A step called a tongue is formed at the tip of the blade. In the flat knitting machine described in Patent Document 1, a pair of front and rear needle beds are provided so as to sandwich the mouth, and the compound needle is selectively driven by a cam mounted on a carriage that reciprocates on the needle bed, Causes movements and transfer actions to be performed. FIG. 12 of Patent Document 1 shows a cam arrangement that guides a bat provided on a needle body and a slider of a compound needle to perform a transfer operation together with a trajectory of the bat. At the time of transfer, the stitch is held by a tongue that is advanced from the upper edge of the hook to the mouth of the hook. In order to prevent the holding stitch from falling off the tongue tip and to smoothly perform the knockover with the slider closing the opening on the hook tip side at the tongue tip, A technique is also known in which the distance between the needle body and the needle stem is increased once and then decreased (see, for example, Patent Document 2).

  In each of FIGS. 13 to 20 of Patent Document 1, the operation state of the compound needle corresponding to the main position on the passing locus in FIG. 12 is shown as a side view of the needle bed. In particular, FIG. 16 shows a state where the slider on the delivery side is advanced to the tooth opening rather than the hook, and the stitch is held by the tongue formed at the head portion of the slider. As shown by 6-b in FIG. 6, the blade at the tip of the slider branches to both sides of the hook, and the tip is expanded. 17 and 18 show a state in which the hook on the eye receiving side is inserted between the blades. FIG. 19 shows a state in which the slider on the delivery side is retracted and the stitches are hung on the needle stem of the needle body on the eye receiving side. FIG. 20 shows a state in which the hook on the eye receiving side is retracted and the stitch is received in the opening on the hook tip side, that is, in the hook.

  The transfer operation on the flat knitting machine is performed when a tissue pattern is knitted or when the number of stitches is increased or decreased. When knitting fabrics knitted on the front and back needle beds on both sides of the knitting width and knitting into a cylindrical shape, especially when performing rib knitting including front and back stitches, stitch formation and transfer Since the steps are performed alternately, the frequency of transfer increases. If needle knitting is performed, a tubular knitted fabric can be knitted by rib knitting even with a pair of front and back needle beds. In the case of using a four-bed flat knitting machine having needle beds in two upper and lower stages on both sides of the mouth, a tubular knitted fabric can be knitted by rib knitting with total needle knitting. In a four-bed flat knitting machine, the front is knitted on the lower side of each needle bed and the back is knitted on the upper side. On the lower side of one needle bed, knitting needles for knitting the face and knitting needles for holding the back stitch knitted on the opposite upper needle bed are alternately arranged. Transfer is performed between knitting and holding the back eye.

  FIG. 3 shows, in a partially simplified manner, a state in which transfer is performed from the lower stage side to the upper stage side on a four-bed flat knitting machine. In FIG. 3, for comparison with the embodiment of the present invention described later with reference to FIG. 1, the operation corresponding to FIG. 19 of Patent Document 1 is divided into three stages (a), (b) and (c). . The flat knitting machine 1 has a front lower needle bed 3a and a front upper needle bed 3b on the front side and a rear lower needle bed 4a and a rear upper needle bed 4b on the rear side, with the mouth 2 interposed therebetween. Each needle bed is inclined so as to be higher when approaching the mouth 2 side and lower when moving away. The front lower needle bed 3a and the front upper needle bed 3b, and the rear lower needle bed 4a and the rear upper needle bed 4b are arranged so as to be plane-symmetric with respect to the central surface 2a of the tooth mouth 2. In the present specification, as the direction in which the knitting needle moves in each needle bed, the direction in which the knitting needle 2 advances to the tooth mouth 2 is described as the upper direction, and the direction in which the knitting needle is retracted is described as the lower direction.

  The knitting needle is accommodated in a needle groove provided in each needle bed, and the leading portion advances and retracts to the tooth opening 2. In this specification, in each needle groove, it describes that the displacement of the direction away from a bottom face is floated, and describes that the displacement of the direction approaching a bottom face sinks. As the knitting needle, a compound needle 5 as disclosed in Patent Document 1 or Patent Document 2 is used. The compound needle 5 includes a needle body 6 and a slider 7. A hook 6a is formed at the leading end of the needle body 6 so as to be the tip of the needle stem 6b. The hook 6a is bent like a bowl and the tip is folded back toward the needle stem 6b. An opening is formed between the tip of the hook 6a and the needle stem 6b. When the hook 6a is pulled, the tip of the hook 6a passes through the descending locus 6c.

The slider 7 is accommodated in a groove provided in the needle stem 6b of the needle body 6, and is movable relative to the needle body 6. The blade 7a at the tip is divided into two pieces, each having a tongue at the head. 7b is formed. The tongue 7b can close the opening between the tip of the hook 6a and the needle stem 6b. When the front lower needle bed 3a is the delivery side and the rear upper needle bed 4b is the eye receiving side, the stitch 8 is held by the tongue 7b on the delivery side and exceeds the upper edge of the hook 6a at the tooth opening 2. And expand to both sides. A sinker 9 is also provided between the knitting needles on both sides of the mouth opening 2. When the hook 6a on the receiving side enters between the blades 7a on the passing side, the slider 7 on the passing side is pulled. The stitch 8 is disengaged from the tongue 7b of the slider 7 and remains near the upper edge of the sinker 9. When the hook 6a on the eye receiving side is retracted, the stitch 8 can be captured and received in the hook 6a.
Japanese Patent No. 3085657 Japanese Patent No. 3886903

  In the transfer using the conventional compound needle 5, the slider 7 on the eye-receiving side stands by in a state where it does not advance from the rear upper needle bed 4 b to the tooth opening 2. Only the needle body 6 is retracted with the hook 6a open. The stitch 8 transferred from the delivery side is captured while the hook 6a on the receipt side is being pulled. The stitch 8 captured by the hook 6a on the eye-receiving side is detached from the upper edge of the tongue 7b on the passing side and remains in the vicinity of the upper edge of the sinker 9. In a state in which the stitch 8 is held by the upper edge of the tongue 7b on the delivery side, a force that spreads the stitch 8 is applied to the knitting yarn. When the stitch 8 comes off the upper edge of the tongue 7 on the delivery side, a force for pulling down the knitted fabric is applied to the stitch 8. If the knitting yarn has sufficient stretchability and slippage, the size of the stitch 8 is smaller than the state of hanging on the delivery side tongue 7b. If the stitch 8 is small, the hook 6a on the eye receiving side is easily caught in the hook 6a when it is drawn into the rear upper needle bed 4b.

  If the knitting yarn is not slippery, has little elongation, or if it is difficult to pull down the knitted fabric, the stitch 8 may not be reduced and may float near the upper edge of the sinker 9 There is. As a case where the force to pull down the knitted fabric is difficult, there are a case where the knitting width is increased by increasing the number of stitches or a turn knitting is performed. When the stitch 8 knitted as the back stitch on the rear upper needle bed 4b is transferred from the front lower needle bed 3a to the rear upper needle bed 4b, as a property of the stitch 8 itself, it floats away from the hook 6a on the eye receiving side. It becomes easy.

  If the stitch 8 is in a floating state, the stitch 8 may be hung on the descending locus 6c at the tip of the hook 6a on the eye-receiving side, or may float further than the descending locus 6c. If the stitch 8 floats above the downward trajectory 6c at the tip of the hook 6a, the stitch 8 cannot be captured in the hook 6a, and the stitch 8 may spill out of the tooth opening 2. If the stitch 8 hits the downward trajectory 6c, the knitting yarn forming the stitch 8 may be broken at the tip of the hook 6a.

  An object of the present invention is to provide a flat knitting machine and a transfer method therefor that can eliminate transfer defects such as spills and break stitches and can perform stable transfer.

The present invention includes needle beds disposed so as to face each other across the mouth, and each needle bed has a needle main body having a hook at the head and a relative movement with respect to the needle main body to the tip end side of the hook. A composite needle having a slider that opens and closes the opening of the needle is arranged side by side as a knitting needle, and the leading portion of the slider is divided into two blades that can advance to the tooth opening rather than the upper edge of the hook so that the hook is sandwiched from both sides. A tongue is formed at the leading end of the blade. On the delivery side, the needle advances to the tooth opening from the upper edge of the hook and opens between the tongues. In the flat knitting machine capable of transferring the hook by inserting the hook of the main body between the tongues on the delivery side and receiving the stitches in the opening of the hook on the eye receiving side,
Hook advancing means for advancing the hook on the receiving side into the tooth opening and entering between the tongues on the passing side;
The bottom of the tongue tip is positioned closer to the needle stem side of the needle body than the downward trajectory of the hook tip before the hook on the eye receiving side is pulled and the hook tip reaches the stitch held between the tongues on the delivery side. Until the stitch is sunk, a tongue advancement means for advancing the slider on the receiving side into the tooth mouth,
It is a flat knitting machine characterized by including.

  Further, in the present invention, the needle-side slider moves the needle on the needle-side needle body when the tongue tip moves relative to the needle body so as to close the opening on the tip-end side of the hook. The distance between the trunk and the tongue tip is once increased and then decreased.

In the present invention, the compound needle is driven by a cam mounted on a carriage that reciprocates along each needle bed,
The cam has the hook advance means and the tongue advance means as drive paths, respectively.

Further, in the present invention, the needle bed is provided in two stages up and down on at least one side of the mouth.
The hook advancing means and the tongue advancing means operate composite needles arranged side by side on an upper needle bed as an eye receiving side for receiving a stitch transferred from the lower side of the opposing needle bed. .

Furthermore, the present invention includes needle beds disposed so as to face each other with a tooth gap interposed therebetween, and each needle bed has a needle body having a hook at the head, and a tip of the hook that moves relative to the needle body. A compound needle having a slider that opens and closes the opening on the side is juxtaposed as a knitting needle, and the leading portion of the slider is separated into two blades that can advance to the tooth opening rather than the upper edge of the hook so as to sandwich the hook from both sides, A tongue is formed at the leading end of each blade. On the delivery side, the stitches are advanced between the upper edges of the hooks and open to the mouth, and the stitches are held between the delivery side tangs. In the transfer method of a flat knitting machine capable of transferring the needle by hooking the hook of the needle body to be advanced into the mouth and then retracting it, receiving the stitch in the opening of the hook on the receiving side,
After the eye catching side hook is advanced into the tooth opening and entering between the tongues on the passing side, before being pulled until the tip of the hook reaches the stitch held between the tongues,
Move the slider on the eye-receiving side into the tooth opening and sink the stitch at the bottom of the tongue tip to the needle stem side of the needle body from the downward trajectory of the hook tip.
This is a transfer method for a flat knitting machine.

  According to the present invention, on the delivery side, the stitches are held between the tongues of the head portion of the slider that advances to the tooth opening from the upper edge of the hook of the head portion of the needle body and opens between them. On the eye-receiving side, the hook of the needle body is caused to enter between the tongues on the side of the delivery by hook advancement means. The tongue advancement means sinks the stitch at the bottom of the tongue tip before the hook on the eye receiving side is pulled in and the tip of the hook reaches the stitch held between the tongues on the delivery side. The stitches can be sunk at least on the needle trunk side of the needle body from the lowering trajectory of the hook tip, so when the hook is retracted even if the stitch is floating when the hook is inserted between the tongues on the delivery side Therefore, it is possible to eliminate transfer defects such as spills and breaks of stitches and to perform stable transfer.

  Further, according to the present invention, when the tongue tip moves relative to the needle body so as to close the opening on the tip side of the hook, the slider on the eye-receiving side moves between the needle stem and the tongue tip of the needle body. The interval increases once and then decreases. Since the bottom of the tongue tip floats and sinks with respect to the needle stem, the stitches in a state of floating from the needle stem can be pushed down to the needle stem side. Since the floating of the stitch can be eliminated, when the hook is pulled into the needle bed on the eye receiving side, it can be surely captured in the opening on the hook tip side.

  According to the present invention, it is possible to improve transfer stability by operating as a hook advancing means and a tongue advancing means on a driving path provided in a cam mounted on the carriage.

  Further, according to the present invention, when transferring the back of the upper needle bed for knitting the back stitch, which is locked by the lower needle bed facing the tooth opening, the back of the tongue is pushed at the tip of the tongue, A stable transfer can be performed by catching in the hook on the eye receiving side.

  Further, according to the present invention, the stitch held between the tongues on the delivery side at the bottom of the tongue tip of the slider on the eye receiving side is submerged on the needle stem side of the needle body from the downward trajectory of the hook tip on the eye receiving side. . Even if the stitches are lifted from the needle stem, the stitches can be reliably captured in the opening of the descending hook tip, and stable transfer can be performed.

FIG. 1 is a simplified diagram showing a characteristic operation during transfer from a lower needle bed to an upper needle bed in a four-bed flat knitting machine 10 as an embodiment of the present invention. FIG. FIG. 2 is a cam layout diagram of the transfer cam 11 used in the flat knitting machine 10 of FIG. FIG. 3 is a side cross-sectional view schematically showing a state in which transfer is performed from the lower side to the upper side in the conventional four-bed flat knitting machine 1.

  FIG. 1 shows a characteristic operation during transfer from a lower needle bed to an upper needle bed in a four-bed flat knitting machine 10 as an embodiment of the present invention. (A), (b), and (c) in FIG. 1 correspond to (a), (b), and (c) in FIG. 3, respectively. In the following description, with respect to the flat knitting machine 10, the same reference numerals are given to the portions corresponding to the flat knitting machine 1, and the overlapping description is omitted.

  In the flat knitting machine 10, the slider 7 of the compound needle 5 of the rear upper needle bed 4b on the eye receiving side is advanced to the tooth opening 2 before the hook 6a is retracted. In FIG. 1A, the tongue 7b starts to advance, and in FIG. 1B, the bottom of the tip of the tongue 7b reaches the position of the stitch 8. The tip of the tongue 7b is curved in a direction away from the bottom. If the tongue 7b is further advanced, the bottom of the tip of the tongue 7b is warped along the stitch 8 as shown in FIG. The stitch 8 has a sinker loop that stays at the upper edge of the sinker 9 as a swing fulcrum, and the needle loop portion between the sinkers 9 is in the direction toward the hook 6a, that is, the needle stem rather than the descending locus 6c at the tip of the hook 6a. It is pushed so that it may sink to 6b side.

  In FIG.1 (c), the hook 6a is also drawn in the direction of the back upper needle bed 4b, and the hook 6a is closed by the front-end | tip of the tongue 7b. If the hook 6a is closed in this way and then retracted into the rear upper needle bed 4b, the stitch 8 captured in the hook 6a can be reliably received. When the hook 6a is closed at the tip of the tongue 7b, as shown in Patent Document 2, the distance between the tip of the tongue and the needle stem of the needle body can be once increased and then decreased. When the stitch 8 is pushed in at the bottom of the tip of the tongue 7b, the tip of the tongue 7b is temporarily lifted from the needle stem 6b and then sunk, so that even if the stitch 8 is lifted, it can be surely sunk and caught in the hook 6a. .

  FIG. 2 shows a schematic cam arrangement of the transfer cam 11 mounted on a carriage provided on each needle bed in the flat knitting machine 10 of FIG. The compound needle 5 of the front lower needle bed 3a is driven by the front lower cam 13 and the compound needle 5 of the rear upper needle bed 4b is driven by the rear upper cam 14. Cams for driving the knitting needles 5 of the rear lower needle bed 4a and the front upper needle bed 3b are the same as the front lower cam 13 and the rear upper cam 14, respectively. The transfer cam 11 is symmetric with respect to the center line 11a so that the same operation can be performed even if the traveling direction of the carriage is reversed. In the following description, the front side and the back side of the center line 11a are shown as the first half and the second side as the second half with respect to the traveling direction.

  In FIG. 2, when the stitch is transferred from the knitting needle 5 of the front lower needle bed 3a to the knitting needle 5 of the rear upper needle bed 4b on the left side of the carriage, the needle body 6 of the knitting needle 5 and the bat of the slider 7 are guided. Paths 16 and 17 are shown, respectively. Thus, the reason that the front lower needle bed 3 a is the delivery side and the rear upper needle bed 4 b is the eye receiving side is based on the needle selection result to the select jack indicated by the path 18. The select jack is connected to the side farther from the tooth opening 2 than the needle body at each knitting needle, and when the bat protruding in the direction of floating from the needle groove is pressed by the presser group 19, the bat of the needle body 6 is brought into the needle groove. Sink.

  The front lower cam 13 includes a needle operation cam 20 and a slider operation cam 21. The needle operation cam 20 is provided with a delivery-side hook advance path 20a and an eye-receiving side hook advance path 20b. The slider operation cam 21 is provided with a delivery-side tongue advance path 21a and a receiving-side tongue advance path 21b. Switching between the delivery side and the eye receiving side is performed by selecting the path 18 of the butt of the select jack based on the needle selection result for each knitting needle. In the case of the delivery side as shown in the figure, the needle selection of the H position is performed, and the butt of the select jack passes through the path where the pressers 22a and 22b are provided. When the first half of the presser 22a is set to be inactive and the second half of the presser 22b is set to be active, the bat of the needle body 6 is guided by the first-half delivery-side hook advance path 20a, and the hook 6a is advanced to the tooth mouth 2. . In the first half, the slider 7 slightly advances toward the tooth opening 2 as the needle body 6 advances toward the tooth opening 2. Furthermore, the bat of the slider 7 is guided to the latter-stage eye-receiving-side tongue advance path 21 a, and the tongue 7 b advances to the tooth mouth 2. The bat of the needle body 6 descends past the top of the delivery side hook advance path 20a, and the hook 6a is drawn into the front lower needle bed 3a. Since the butt of the select jack sinks due to the action of the presser 22b in the second half, the bat of the needle body 6 does not advance into the tooth opening 2 in the second half.

  When selecting the needle so that the select jack is in the A position, the butt of the select jack passes through a path in which the pressers 23a, 23b, 23c, and 23d are provided. If the first half pressers 23a and 23b are set to operate and the second half pressers 23c and 23d are set to non-working, the bat of the needle body 6 does not pass through the first half delivery side hook advancing path 20a, and the second half receiving side hooks. It passes through the advance route 20b. The bat of the slider 7 advances only slightly toward the tooth mouth 2 side in the latter half of the receiving side tongue advance path 21b.

  When the needle is selected so that the select jack is in the B position, the butt of the select jack passes through the path where the presser 24 is provided. The presser 24 always protrudes, and the needle body 6 and the slider 7 do not advance into the tooth mouth 2 and do not perform an operation related to transfer. In addition, the position of the bat of the needle body 6 corresponding to FIGS. 1A, 1B, and 1C is indicated by 26a, 26b, and 26c, and the position of the bat of the slider 7 is indicated by 27a, 27b, and 27c, respectively. .

  The rear upper cam 14 includes a needle operation cam 30 and a slider operation cam 31. The needle operation cam 30 is provided with an eye receiving side hook advance path 30a and a hand side hook advance path 30b. The slider operation cam 31 is provided with a receiving-side tongue advance path 31a and a delivery-side tongue advance path 31b. Switching between the eye receiving side and the handing side is performed by selecting the path 18 of the butt of the select jack based on the needle selection result for each knitting needle. In the case of the receiving side as shown in the drawing, the needle selection of the H position is performed, and the butt of the select jack passes through the path where the pressers 32a and 32b are provided. When the first half of the presser 32a is set to operate and the second half of the presser 32b is set to non-working, the bat of the needle body 6 is guided by the second half of the eye receiving side hook advancing path 30a, and the hook 6a is advanced to the tooth mouth 2. . The bat of the slider 7 is guided to the latter-stage eye-receiving-side tongue advance path 31a, and the tongue 7b advances to the tooth mouth 2, so that the operations shown in FIGS. 1 (a), (b) and (c) are performed. be able to.

  When selecting the needle so that the select jack is in the A position, the butt of the select jack passes through the path where the pressers 33a and 33b are provided. If the first half of the presser 33a is set to be inactive and the second half of the presser 33b is set to be active, the butt of the needle body 6 advances to the tooth opening 2 through the first half delivery-side hook advance path 30b. Do not advance to 2. The bat of the slider 7 is attached to the needle body 6 in the first half through the delivery-side tongue advancement path 31b, and advances into the tooth mouth 2 through the eye-receiving-side tongue advancement path 31a. To do. On the delivery side, it is not necessary to advance the tongue 7b into the tooth mouth 2, but the route is shared. It is also possible to switch the route so that the tongue 7b does not advance into the tooth mouth 2 on the delivery side. However, the configuration of the slider operation cam 31 can be simplified if switching is not performed.

  When the needle is selected so that the select jack is in the B position, the butt of the select jack passes through the path where the presser 34 is provided. The presser 34 always protrudes, and the needle body 6 and the slider 7 do not advance into the tooth mouth 2 and do not perform an operation related to transfer. The positions of the bats of the needle body 6 corresponding to FIGS. 1A, 1B, and 1C are indicated by 36a, 36b, and 36c, respectively, and the positions of the bats of the slider 7 are indicated by 37a, 37b, and 37c, respectively. .

  In the transfer to which the present invention is applied, the hook 6a on the eye-receiving side is slightly retracted and is closed by the tongue 7b that advances to the mouth 2 and then retracted to the rear upper needle bed 4b. However, the hook 6a is retracted until it is closed. Alternatively, only the tongue 7b may be advanced. Further, the tongue 7b may be advanced and held until the stitch 8 is pushed down, and only the hook 6a may be pulled down.

  A flat knitting machine 10 in FIG. 1 is a four-bed machine, and the present invention is applied to transfer from a lower needle bed to an upper needle bed facing the tooth opening 2. However, the present invention can be implemented in other cases as long as it does not depart from the gist of the present invention. For example, the present invention can be applied to transfer from an upper needle bed to a lower needle bed or transfer between lower needle beds in a four-bed machine. Furthermore, the present invention can be applied to transfer between needle beds even in a two-bed machine. Although the knitting needle is driven by the transfer cam 11, the present invention can be similarly applied to a composite cam having both functions of transfer and knitting by switching the path. Further, although the transfer cam 11 enables the same transfer in both directions of the carriage reciprocating, it is needless to say that the transfer may be performed only in a specific direction. Furthermore, the driving of the knitting needle is not limited to the cam, and for example, the needle body 6 or the slider 7 may be provided with an individual driving actuator or the like.
