Description

Flat knitting machine and its stitch transfer method {WEFT KNITTING MACHINE AND STITCH TRANSFER METHOD FOR SAME}

The present invention relates to a composite needle in which a head of a slider for opening and closing a hook is divided into two blades that can advance into a needle bed gap rather than a hook upper edge. A flat knitting machine having a composite needle as a knitting needle, and a stitch transfer method in the flat knitting machine.

Conventionally, as the knitting needle of the flat knitting machine, a compound needle is used in which the head of the slider for opening and closing the hook is divided into two blades which can advance into the needle bed gap rather than the upper edge of the hook. This is known (for example, refer patent document 1). At the distal end of the blade, a step called a tongue is formed. In the flat knitting machine described in Patent Literature 1, a composite needle is provided by a cam mounted on a carriage for providing a pair of front and rear needle beds with a needle bed gap therebetween and reciprocating the needle bed. Is selectively driven to perform a knitting operation or a stitch transfer operation. In Fig. 12 of Patent Document 1, a cam arrangement for guiding a butt formed on the needle body of the compound needle and the slider to perform a stitch transfer operation is shown together with the pass trajectory of the butt. In the case of stitch transfer, the stitch delivery side supports the stitch by the tongue which is advanced into the needle bed gap rather than the hook upper edge. The tip of the tongue when closing the hook to prevent the supported stitch from falling off the tongue tip and to smooth knock over while the slider is closing the opening on the hook tip side by the tongue tip. Also known is a technique of increasing the interval between the needle body and the needle stem of the needle body and then decreasing it (see Patent Document 2, for example).

In Figs. 13 to 20 of Patent Document 1, the operating state of the composite needle corresponding to the main position on the passage trajectory of Fig. 12 is shown as a side view of the needle bed. In particular, Fig. 16 shows a state in which the slider on the stitch delivery side moves into the needle bed gap rather than the hook, and the stitch is supported by the tongue formed at the head of the slider. As shown in Fig. 6-B in Fig. 6, the blades at the tip of the slider are branched to both sides of the hook to widen the tip. 17 and 18 show a state in which the hook on the stitch receiving side enters between the blades. 19 shows a state in which the slider on the stitch delivery side is inserted and the stitch is hung on the needle stem of the needle body on the stitch receiving side. 20 shows a state in which the hook on the stitch receiving side is inserted and the stitch is received in the opening on the hook tip side, that is, in the hook.

The stitch transfer operation in the flat knitting machine is performed when a structure pattern is knitted or when the number of stitches is increased or decreased. Rib knitting including front stitch and back stitch, especially in the case of knitting the knitted fabrics knitted in the front and rear needle beds by connecting them from both sides of the knitting width to form a tubular shape. In the case of forming, etc., since the formation of the stitches and the stitch transfer are alternately performed, the frequency of the stitch transfer increases. When a draw-off knitting is carried out, a tubular knitted fabric can be knitted by rib knitting even in a pair of front and back needle beds. When using the four-bed flat knitting machine provided with the needle bed in the upper and lower two stages on both sides of a needle bed gap, a cylindrical knitted fabric can be knitted by rib knitting by needle knitting. In the flat knitting machine of 4 sheets, the front stitch is knitted on the lower end side of each needle bed, and the back stitch is knitted on the upper end side. On the lower end side of one needle bed, a knitting needle for knitting the front stitch and an knitting needle for supporting the back stitch knitting on the opposite needle bed are alternately arranged. A stitch transfer is made between the knitting of the back stitch and the support.

Fig. 3 shows a partially simplified view of stitch transfer from the lower end side to the upper end side in the flat knitting machine of a four-bed bed. In FIG. 3, the operation | movement corresponding to FIG. 19 of patent document 1 is divided into three steps of (a), (b), and (c), in order to compare with embodiment of this invention mentioned later in FIG. The flat knitting machine 1 has a front lower needle bed 3a and a front upper needle bed 3b on the front side with the needle bed gap 2 interposed therebetween. A rear lower needle bed 4a and a rear upper needle bed 4b are provided. Each needle bed is inclined so as to be closer to the needle bed gap 2 and lower when it is farther 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 face symmetrical with respect to the center plane 2a of the needle bed gap 2. It is arrange | positioned so that it may become a surface. In this specification, as the direction in which the needle needle moves in each needle bed, the direction which advances to the needle bed gap 2 is described as an upper direction and a direction inserted into the needle bed as the lower side.

The knitting needle is accommodated in the needle grooves formed in each needle bed, and the leading part advances and retreats into the needle bed gap 2. In this specification, it is described in each needle groove that the displacement of the direction falling from the bottom surface is floated, and the displacement of the direction approaching a bottom surface will be settled. As the knitting needle, a composite needle 5 as disclosed in Patent Document 1 or Patent Document 2 is used. The composite needle 5 includes a needle body 6 and a slider 7. At the head of the needle body 6, a hook 6a is formed so as to be the tip of the needle stem 6b. The hook 6a is curved in the shape of a claw, and is bent so that the tip thereof returns to the needle stem 6b side. An opening is formed between the tip of the hook 6a and the needle stem 6b. When the hook 6a is inserted, the tip of the hook 6a passes through the descending trajectory 6c.

The slider 7 is accommodated in a groove formed in the needle stem 6b of the needle body 6, and can be moved relative to the needle body 6, and the blades 7a of the tip portion are divided into two pieces, respectively. The tongue 7b is formed in the head part. 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 becomes the stitch delivery side, and the rear upper needle bed 4b becomes the stitch receiving side, the stitch 8 is supported by the tongue 7b on the stitch delivery side, and the needle bed The gap 2 extends beyond the upper edge of the hook 6a to both sides and advances. On both sides of the needle bed gap 2, a sinker 9 is also formed between the knitting needles. When the hook 6a on the stitch receiving side enters between the blades 7a on the stitch delivery side, the slider 7 on the stitch delivery side is drawn in. Stitch 8 exits from tongue 7b of slider 7 and stops near the upper rim of sinker 9. When the hook 6a on the stitch receiving side is pulled in, the stitch 8 can be captured in the hook 6a.

Japanese Patent No. 3085657 Japanese Patent No. 3886903

In the stitch transfer using the conventional composite needle 5, the slider 7 on the stitch receiving side waits in the state of not advancing into the needle bed gap 2 from the rear upper needle bed 4b. Only the needle body 6 is drawn in with the hook 6a open. The stitch 8 transferred from the stitch delivery side to the stitch 8 is captured while the hook 6a on the stitch receiving side is drawn in. The stitch 8 captured by the hook 6a on the stitch receiving side exits from the upper edge of the tongue 7b on the stitch delivery side and stops near the upper edge of the sinker 9. In the state where the stitch 8 is supported at the upper edge of the tongue 7b on the stitch delivery side, a force for widening the stitch 8 is bound to the knitting yarn. When the stitch 8 is pulled out of the upper edge of the tongue 7 on the stitch delivery side, the stitch 8 is subjected to a force for lowering the knitted fabric or the like. If there is sufficient elasticity or slippage for knitting, the size of the stitch 8 becomes smaller than the state caught on the tongue 7b on the stitch delivery side. When the stitch 8 becomes small, when the hook 6a of the stitch receiving side enters the rear upper needle bed 4b, it is easy to capture in the hook 6a.

When the slip is bad as the knitting yarn, or when the elongation is small, when the force for lowering the knit fabric is difficult to act, the stitch 8 does not become small, and there is a possibility of floating around the upper edge of the sinker 9. have. As a case where the force which lowers a knit fabric is hard to act, there may be a case where the knitting width is extended by increasing a stitch, or a back knitting is performed. In the case of stitch transfer from the front lower needle bed 4b to the rear upper needle bed 4b from the front lower needle bed 3a to the rear upper needle bed 4b, as a property of the stitch 8 itself, It becomes easy to float in the direction falling from the hook 6a of the stitch receiving side.

When the stitch 8 is in a floating state, there is a possibility that it is caught by the falling trajectory 6c of the tip of the hook 6a on the stitch receiving side or floats more than the falling trajectory 6c. If the stitch 8 floats more than the falling trajectory 6c of the tip of the hook 6a, the stitch 8 cannot be captured in the hook 6a, and the stitch 8 leaves the needle bed gap 2. Stitch drop occurs and is discarded. If the stitch 8 is caught by the falling trajectory 6c, the knitting yarn forming the stitch 8 may be broken at the tip of the hook 6a.

SUMMARY OF THE INVENTION An object of the present invention is to provide a flat knitting machine and a stitch transfer method capable of stably transferring stitches by eliminating defects in stitch transfer such as stitch drop and breaking of stitches.

The present invention has a needle bed which is provided to face each other with a needle bed gap interposed therebetween, and each needle bed is provided with a hook at its head. A composite needle having a needle body provided with a slider for moving relative to the needle body and opening and closing the opening on the tip side of the hook is arranged as a needle. And the head of the slider is divided into two blades which can be inserted into the needle bed gap from the upper edge of the hook by inserting the hooks from both sides, and a tongue is formed at the head of each blade. On the stitch delivery side, the stitch advances into the needle bed gap rather than the upper edge of the hook and supports the stitch between the opening tongues. On the receiving side, the hook of the needle main body advancing into the needle bed gap is inserted between the tongues on the stitch delivery side, and then retracted, and the stitch is received in the opening of the hook on the stitch receiving side to perform a stitch transfer. In the flat knitting machine which can be used,

Hook advance means for advancing the hook on the stitch receiving side into the needle bed gap and intruding between the tongue on the stitch delivery side;

Before the hook of the stitch receiving side enters and the tip of the hook reaches the stitch supported between the tongues on the stitch delivery side, the bottom of the tongue tip is closer to the needle stem side of the needle body than the lower track of the hook tip. Tongue exit means for advancing the slider on the stitch receiving side to the needle bed gap until the stitch has subsided.

It is a flat knitting machine characterized by including.

Further, in the present invention, the slider on the stitch receiving side is spaced between the needle stem and the tongue tip of the needle body on the stitch receiving side when the tongue tip is moved relative to the needle body so as to close the opening on the tip side of the hook. It is characterized by decreasing once it has increased.

In the present invention, the composite needle is driven by a cam mounted on the carriage reciprocating along each needle bed,

The cam is provided with the hook advancement means and the tongue advancement means as driving paths, respectively.

In the present invention, the needle bed is provided in two stages above and below at least one side of the needle bed gap,

The hook advancing means and the tongue advancing means serve as a stitch receiving side for receiving a stitch which is stitch-delivered from a lower end side of an opposing needle bed, with a composite needle installed side by side on an upper needle bed. It is characterized by operating.

In addition, the present invention includes a needle bed provided to face each other with a needle bed gap interposed therebetween, each needle bed having a hook body having a hook at its head and an opening at the tip side of the hook relative to the needle body. A composite needle having a slider for opening and closing the needle is installed side by side as a single needle, and the head of the slider is divided into two blades which can be inserted into the needle bed gap rather than the upper edge of the hook by inserting the hook from both sides. Tongues are formed at the head, and the stitch delivery hooks the needle body to advance to the needle bed gap from the upper edge of the hook and to support the stitches between the openings of the needles, and to the needle receiving gap from the needle receiving side. Break in between tongue on delivery side Incoming after Keane, and in that the stitch transfer method of the flat knitting machine available to receive the stitches of the stitch in the opening of the receiver bingcheuk hook to transfer a stitch,

After advancing the hook on the stitch receiving side into the needle bed gap and infiltrating it between the tongues on the stitch delivery side, before the tip of the hook reaches the stitch supported between the tongues,

By moving the slider on the stitch receiving side into the needle bed gap, the needle is settled at the bottom of the tongue tip, rather than the downward track of the hook tip.

It is a stitch transfer method of the flat knitting machine characterized by the above-mentioned.

According to the present invention, on the stitch delivery side, stitches are supported between the tongues of the heads of the sliders which advance into the needle bed gap rather than the hook upper edges of the head parts of the needle body and open to each other. On the stitch receiving side, the hook of the needle main body is intruded between the tongues on the stitch delivery side by the hook advance means. The tongue advancement means sinks the stitch at the bottom of the tongue tip before the hook on the stitch receiving side enters and the tip of the hook reaches the stitch supported between the tongue on the stitch delivery side. Since the stitch can sink to the needle stem side of the needle body at least than the descending trajectory of the hook tip, even if the stitch is infiltrated between the tongues on the stitch delivery side, the stitch drops and stitches when the hook is drawn in. Stitch transfer defects such as destroying can be eliminated, resulting in stable stitch transfer.

According to the present invention, the slider on the stitch receiving side decreases after the interval between the needle stem of the needle body and the tongue tip increases once when the tongue tip moves relative to the needle body so as to close the opening on the tip side of the hook. Since the bottom of the tongue tip is crushed against the needle stem, the stitch in the floating state from the needle stem can be pushed down to the needle stem side. Since the stitches can be eliminated, the hooks can be reliably captured in the openings on the hook tip side when the hooks are pulled into the needle bed on the stitch receiving side.

According to the present invention, the stability of the stitch transfer can be improved by operating as a hook advance means and a tongue advance means through a drive path formed in the cam mounted on the carriage.

According to the present invention, when the stitch transfer is performed on the needle bed at the upper end of the back stitch to be stitched at the needle bed at the opposite lower end with the needle bed gap therebetween, the tip of the tongue is easily floated. It is press-fitted in, and it is possible to perform stable stitch transfer by capturing in the hook on the stitch receiving side.

Further, according to the present invention, a stitch supported between the tongue on the stitch delivery side at the bottom of the tongue tip of the slider on the stitch receiving side is sinked to the needle stem side of the needle body rather than the descending trajectory of the hook tip on the stitch receiving side. Even if the stitches float from the needle stem, the descending hook can be reliably captured in the opening of the hook tip, so that a stable stitch transfer can be achieved.

Fig. 1 is an embodiment of the present invention, in which the flat knitting machine 10 of a four-bed bed shows a simplified characteristic operation during stitch transfer from the needle bed on the lower side to the needle bed on the upper side. It is a cross section.
FIG. 2 is a cam arrangement diagram of the stitch transfer cam 11 used in the flat knitting machine 10 of FIG.
Fig. 3 is a side sectional view schematically showing a state in which stitch transfer is performed from the lower end side to the upper end side in the flat knitting machine 1 of a conventional four-sheet bed.

Fig. 1 shows an exemplary operation of stitch stitching from a needle bed on the lower side to a needle bed on the upper side in the flat knitting machine 10 of a four-sheet as one embodiment of the present invention. Figures 1 (a), (b) and (C) correspond to Figures 3 (a), (b) and (c), respectively. In the following description, the part which corresponds to the flat knitting machine 1 with respect to the flat knitting machine 10 is attached | subjected with the same code | symbol, and the overlapping description is abbreviate | omitted.

In the flat knitting machine 10, the slider of the composite needle 5 in the rear upper needle bed 4b on the stitch receiving side. 7) advances into the needle bed gap 2 before the hook 6a is introduced. In Fig. 1 (a), the advance of the tongue 7b starts, and in Fig. 1 (b) the bottom of the tip of the tongue 7b reaches the position of the stitch 8. The tip end of the tongue 7b is curved in the direction falling from the bottom part. When the tongue 7b is further advanced, the bottom portion of the tip of the tongue 7b is raised along the stitch 8 as shown in Fig. 1C. As for the stitch 8, the sinker loop which stops at the upper edge of the sinker 9 becomes a swing point, and the part of the needle loop between the sinkers 9 hooks. (6a) It press-fits so that it may sink to the needle stem 6b side rather than the fall trace 6c of the direction of the inside of the hook 6a.

In Fig. 1C, the hook 6a is also drawn in the direction of the rear upper needle bed 4b, and the hook 6a is closed at the tip of the tongue 7b. In this way, when the hook 6a is closed and then inserted into the rear upper needle bed 4b, the stitch 8 captured in the hook 6a can be reliably received. When closing the hook 6a at the tip of the tongue 7b, as shown in Patent Literature 2, the distance between the tip of the tongue and the needle stem of the needle body may be increased once. When pressing the stitch 8 at the tip bottom of the tongue 7b, the tip of the tongue 7b is settled after floating once from the needle stem 6b, so that even if the stitch 8 is floating, it is reliably sinking and hooking It can capture in (6a).

FIG. 2 shows a schematic cam arrangement of a stitch transfer cam 11 mounted on a carriage provided in each needle bed in the flat knitting machine 10 of FIG. The composite needle 5 of the front lower needle bed 3a is driven by the front lower cam 13, and the composite needle 5 of the rear needle bed 4b is It is driven by a rear upper cam 14. The cams driving the compound needles 5 of the rear lower needle bed 4a and the front upper needle bed 3b are equal to the front lower cam 13 and the rear upper cam 14, respectively. The stitch transfer cam 11 is symmetrical with the center line 11a so as to perform an equivalent operation even if the running direction of the carriage is reversed. In the following description, the leading side is shown as the front half and the trailing side as the rear half of the running line with respect to the running direction.

In Fig. 2, in the case where the stitch is moved from the compound needle 5 of the front lower needle bed 3a to the compound needle 5 of the rear upper needle bed 4b by the left row of the carriage, The paths 16 and 17 through which the butt of the needle body 6 and the slider 7 of (5) are guided are shown, respectively. In this way, it is the select jack indicated by the path 18 that the front lower needle bed 3a becomes the stitch delivering side and the rear upper needle bed 4b becomes the stitch receiving side. Based on the result of the selection to (select jack). The select jack is connected to the side farther from the needle bed gap 2 than the needle body in each knitting needle, and when the butt projecting in the floating direction from the needle groove is pressed by the presser group 19, the needle body ( 6) Set the butt in the needle groove.

The front lower end cam 13 includes a needle manipulation cam 20 and a slider manipulation cam 21. The needle operating cam 20 is provided with a stitch delivery side hook advance path 20a and a stitch receiving side hook advance path 20b. In the slider operation cam 21, a stitch delivery side tongue advance path 21a and a stitch receiving side tongue advance path 21b are formed. The switching between the stitch delivery side and the stitch receiving side is made by selecting the path 18 of the butt of the select jack based on the result of the needle selection for each needle. As shown in the figure, in the case of the stitch delivery side, the H position is set in advance, and the butt of the select jack passes through the path where the pressers 22a and 22b are installed. When the first presser 22a is set to non-working and the second presser 22b to acting, the butt of the needle body 6 is guided to the hook delivery path 20a of the stitch delivery side of the first half. Then, the hook 6a is advanced to the needle bed gap 2. In the first half, the slider 7 accompanies advancing into the needle bed gap 2 of the needle body 6 and slightly advances toward the needle bed gap 2 side. In addition, the butt of the slider 7 is guided to the stitch receiving-side tongue advance path 21a in the latter half, and the tongue 7b advances to the needle bed gap 2. The butt of the needle body 6 descends past the top of the hook delivery path 20a of the stitch delivery side, and the hook 6a is led into the needle bed 3a at the front lower end. Since the butt of the select jack sinks under the action of the latter presser 22b, the butt of the needle body 6 does not advance to the needle bed gap 2 of the latter half.

When the select jack is set to the A position, the butt of the select jack passes through the path where the pressers 23a, 23b, 23c, and 23d are installed. When the first half pressers 23a and 23b are acted on and the second half pressers 23c and 23d are set to inactive, the butt of the needle body 6 passes through the hook delivery path 20a of the stitch delivery side of the first half. It does not go but passes the latter stitch receiving side hook advance path 20b. The butt of the slider 7 only propagates to the needle bed gap 2 side for the second time on the stitch receiving side tongue advance path 21b.

When the select jack is set to the B position, the butt of the select jack passes through the path where the presser 24 is installed. The presser 24 always protrudes, and the needle body 6 and the slider 7 do not advance to the needle bed gap 2, and do not operate on the stitch transfer. In addition, the positions of the butts of the needle body 6 corresponding to FIGS. 1 (a), (b) and (c) are shown as 26a, 26b, and 26c, respectively, and the positions of the butts of the slider 7 are 27a, 27b, and 27c. Respectively.

The rear upper cam 14 includes a needle operating cam 30 and a slider operating cam 31. The needle operating cam 30 has a stitch receiving side hook advance path 30a and a stitch delivery side hook advance path 30b. On the slider operation cam 31, a stitch receiving side tongue advance path 31a and a stitch delivery side tongue advance path 31b are formed. The switching between the stitch receiving side and the stitch delivery side is made by selection of the path 18 of the butt of the select jack based on the result of the needle selection for each needle. As shown in the figure, when the stitch receiving side is used, the H position is set in advance, and the butt of the select jack passes through the path where the pressers 32a and 32b are provided. When the first presser 32a is acted on and the second presser 32b is set to inactive, the butt of the needle body 6 is guided to the second stitch receiving-side hook advance path 30a, whereby the hook ( 6a) is advanced to the needle bed gap 2. Butts of the slider 7 are guided to the stitch returning side tongue advance path 31a in the second half, and the tongue 7b advances into the needle bed gap 2, so that FIGS. You can do this as shown in.

When the select jack is set to the A position, the butt of the select jack passes through the path where the presses 33a and 33b are installed. When the first presser 33a is set to the non-acting action and the second presser 33b is set to the action, the butt of the needle body 6 passes through the needle bed gap ( 2), the latter half does not enter the needle bed gap (2). The butt of the slider 7 enters the needle bed gap 2 through the stitch delivery side side advance path 31b, the first half of which is attached to the needle body 6, and the second half passes through the stitch receiving side tongue advance path 31a. Through the needle bed gap (2). It is not necessary to advance the tongue 7b into the needle bed gap 2 on the stitch delivery side, but the path is shared. The path may be switched so that the tongue 7b does not advance into the needle bed gap 2 on the stitch delivery side. However, it is possible to simplify the configuration by not switching the slider operation cam 31.

When the select jack is set to the B position, the butt of the select jack passes through the path where the presser 34 is installed. The presser 34 always protrudes, and the needle body 6 and the slider 7 do not advance to the needle bed gap 2, and do not operate on the stitch transfer. In addition, the positions of the butts of the needle body 6 corresponding to FIGS. 1 (a), (b) and (c) are shown as 36a, 36b, and 36c, respectively, and the positions of the butts of the slider 7 are 37a, 37b, 37c. Respectively.

In the stitch transfer to which the present invention is applied, the hook 6a on the stitch receiving side is pulled in a little, and closed by the tongue 7b advancing into the needle bed gap 2 and then into the rear upper needle bed 4b. However, only the tongue 7b may be advanced without pulling the hook 6a until it is closed. In addition, the tongue 7b may be made to stop and advance until the stitch 8 is pushed down, and only the hook 6a may be lowered.

The flat knitting machine 10 shown in Fig. 1 is a four-bed bed, which is a needle bed on the upper side facing the needle bed gap 2 with the needle bed gap 2 interposed therebetween. The present invention is applied to a stitch transfer. However, as long as it does not deviate from the main point of this invention, it can implement also in other cases. For example, the present invention can be applied to a stitch transfer between a needle bed at the upper end side and a needle bed at the lower end side or a needle transfer at the lower end side in a four-sheet bed machine. The present invention can also be applied to a stitch transfer between needle beds in a two-bed machine. The knitting needle is driven by the stitch transfer cam 11, but the present invention can be similarly applied to a composite cam having both functions of the stitch transfer and knitting as long as the path is switched. In addition, although the stitch transfer cam 11 can perform the same stitch transfer in both directions of the carriage reciprocating, it is natural that the stitch transfer may be performed only in a specific direction. In addition, the driving of the single needle is not limited to the cam, and for example, a driving actuator or the like may be separately provided on the needle body 6 or the slider 7.

A needle bed provided to face each other with a needle bed gap interposed therebetween, each needle bed having a needle body having a hook at its head and a slider for opening and closing the opening at the tip side of the hook relative to the needle body; Combined needles are provided side by side with a single needle, the leading part of the slider is divided into two blades that can be inserted into the needle bed gap from the upper edge of the hook by inserting the hook from both sides, the tongue at the top of each blade On the stitch delivery side, the hook of the needle body for advancing into the needle bed gap rather than the upper edge of the hook to support the stitches and advancing into the needle bed gap on the stitch receiving side is inserted between the tongues on the stitch delivery side. After infiltrating into a hole, it pulls in and stitches in the opening of the hook of the stitch receiving side. Taking in the stitch transfer is the method of the flat knitting machine available for the transfer stitch,
After advancing the hook on the stitch receiving side into the needle bed gap and infiltrating it between the tongues on the stitch delivery side, before the tip of the hook reaches the stitch supported between the tongues,
By moving the slider on the stitch receiving side into the needle bed gap, the needle is settled at the bottom of the tongue tip, rather than the downward track of the hook tip.
