FLAT KNITTING MACHINE FOR KNITTING TUBULAR KNITTED FABRIC}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat knitting machine for knitting a tubular knitted fabric having at least a pair of needle beds and knitting a knitted fabric in a tubular shape.

Conventionally, in the flat knitting machine provided with at least one pair of needle beds facing each other in a needle bed gap, socks and gloves can be knitted as a cylindrical knitted fabric. It is known that it can (for example, refer patent document 1). In the flat knitting machine which knits socks and gloves exclusively, the knitting needle used for knitting is selected using the line needle drum (for example, refer patent document 2).

Fig. 6 is a diagram mainly showing the cam system of the schematic configuration of a flat knitting machine 1 for knitting a cylindrical knitted fabric used for knitting socks or gloves. The flat knitting machine 1 for knitting a tubular knitted fabric includes a front needle bed and a back needle bed. Both needle beds are provided with carriages for reciprocating to selectively drive the knitting needles to perform knitting operations. The cam system is mounted on a carriage, divided into cam plates 2a and 2b in contact with the front and rear needle beds, and a plurality of cams are arranged, respectively. Cams arranged on the cam plates 2a and 2b in contact with each needle bed are approximately equivalent, and corresponding parts are denoted by the same reference numerals. The arrangement of the cams is shown in a state viewed from the back side of the cam plates 2a and 2b. As the main cams arranged in both, a center cam 3, a needle raising cam 4, a stitch cam 5 and a bridge cam 6 , A presser cam 7, a needle guide cam 8, and a resilient raising cam 9 that can be mounted are provided. A needle bed gap 10 is formed in the middle of the two needle beds. The two needle beds facing each other on both sides of the needle bed gap 10 are inclined such that the side of the needle bed gap 10 is high and the side falling from the needle bed gap 10 is lowered, but is not inclined for convenience of explanation. Represented by state.

In each needle bed, needle grooves are formed in the vertical direction in the drawing. Needle grooves are formed side by side in the left and right direction of the drawing, each needle groove is accommodated in a state capable of sliding displacement (advancing) the needle needle (11) advancing to the needle bed gap (10) . On the left side of the figure, the knitting needle 11 is shown as a partial configuration seen from the side. Knitting needle 11 includes a needle body 12 and a jack (jack) (13). The needle body 12 on the needle bed gap 10 side is retracted to the needle bed gap butt 12a projecting from the needle groove to the carriage side and the needle bed gap 10 to perform the knitting operation. A hook 12b and a latch 12c. The jack 13 has a drive butt 13a that protrudes from the needle groove toward the carriage side.

In the knitting machine 1 for knitting a cylindrical knit fabric for knitting socks or gloves, the knitting yarn is spun in a fixed direction, for example, clockwise in the drawing, and the knitted fabric is knitted in a cylindrical shape. In this case, if the carriage travels in the right direction of the drawing, the carriage becomes forward in the rear needle bed and reverse in the front needle bed. The stitch forming operation as the knitting needle 11 is carried out by moving the driving butt 13a to the center cam 3, the needling cam 4, and the stitch cam 5 as shown in the forward direction 13aF on the rear needle bed side. Guide to follow the pass path (13aFT) by). The forward direction 12aF of the needle bed gap side butt 12a draws a passage 12aFT. When the elastic raising cam 9 is actuated, the braid 11 is advanced to the needle bed gap 10 in advance of the center cam 3, as indicated by the broken line, and is called a rubber thread. Elastic yarns can be inserted. If the needle bed gap side butt 12a is formed at a height to form a high difference, and the low needle bed gap side butt 12a is prevented from working even when the elastic raising cam 9 protrudes, a rubber thread is inserted. The knitting needle 11 can be selected.

On the front needle bed side, the needle bed gap side butt 12a and the drive butt 13a are moved along the pass paths 12aRT and 13aRT in the reverse directions 12aR and 13aR. On the front needle bed side, an actuating cam 14 capable of protruding at the start of knitting is provided, but it sinks when knitting a cylindrical knitted fabric. In the upper edge 6a of the bridge cam 6, the needle bed gap side butt 12a is returned to the needle bed gap 10 side by ΔL.

In this way, for example, the carriage on the rear needle bed side forms a stitch in the forward direction, while the carriage on the front needle bed side, for example, returns the knitting needle 11 in the reverse direction. When the carriage reverses the running direction, one carriage returns the knitting needle 11 in the reverse direction, and the other carriage forms a stitch in the forward direction. At the end of the drive in the forward direction 13aF, the drive butt 13a is inserted in the direction away from the needle bed gap 10 by the stitch cam 5. In the state where the knitting needle 11 is pulled in, the hook 12b for engaging the formed stitches is also inserted into the needle groove on the needle bed side away from the needle bed gap 10. In the needle bed gap 10, the already knitted fabric is lowered downward to apply a downward tension to the stitches engaged with the hooks 12b of the knitting needle 11, thereby making it easier to knit a new knitted fabric. Let's do it. When the hook 12b is inserted on the needle bed side, even if the knitted fabric is lowered downward by the needle bed gap 10, the direction of tension applied to the stitch engaged with the hook 12b is along the bottom of the needle groove. Direction and not downward. For this reason, when knitting in the reverse direction 12aF, the needle bed gap side butt 12a is returned from the upper edge 6a of the bridge cam 6 so that the hook 12b is close to the needle bed gap 10 and knitted. The fabric is made easy to descend from the hook 12b to the needle bed gap 10.

When knitting a cylindrical knitted fabric by the cylindrical knitted fabric knitting machine 1, the knitting needle 11 serving as the end of the knitting width or the portion of the portion close to the end of the needle bed on the forward side where the knitting is finished ( The stitches joined to 11 become end stitches. In the end stitch, there is a fear that the knitting yarn is pulled out by the knitting start in which the carriage is reversed and becomes forward in the opposite needle bed, so that the size of the stitch becomes small. In patent document 1, even if the knitting yarn is pulled from the opposite needle bed side, the knitting needle preventing means for restricting the knitting needle 11 from advancing to the needle bed gap 10 side is provided.

When the end stitch becomes small, the size of the stitch is provided by the increase in the distance between the stitches and the stitches in which the end stitches are blocked at the boundary portion connecting the knitted fabrics knitted in the opposite needle beds with the needle bed gap 10 therebetween. This results in the failure of the stitches and damages the appearance. However, the provision of the sedimentation preventing means such as Patent Document 1 requires the addition of a new mechanism.

It is an object of the present invention to avoid the addition of a new mechanism as much as possible, and to prevent the occurrence of a stitch that is not provided at the boundary portion of the cylindrical knitted fabric and the breakage of the stitch. To provide.

In the present invention, a pair of needle beds are arranged before and after with a needle bed gap interposed therebetween, and each needle bed accommodates a needle needle to advance and retreat to the needle bed gap. Needle grooves for guiding the sliding movement in the direction to be formed (needle groove) are formed side by side,

The needle butt is mounted on a carriage that reciprocates in a side-by-side direction, and the driving butt of the needle needle protruding from the needle groove is moved in a different forward direction for each needle bed. After the needle needle advances to the needle bed gap, the needle needle is retracted to the needle bed to operate the stitch forming operation. When the needle needle is moved in the reverse direction, the needle forming operation is prevented. Flat knitting machine for knitting a cylindrical knitted fabric having a cam system that can be connected at both ends of the knitting width and knitted into a tubular shape. ),

A needle needle in the knitting width used to knit the knitting fabric in each needle bed is selected so that the driving butt protrudes from the needle groove, and the protruding height is lower than other knitting needles in the knitting width at the knitting needle at the end of the knitting width. (選 針 system),

It is disposed in the path through which the driving butt protruding from the needle groove passes in the reverse direction, and passes through the driving butt of the knitting needle at the end portion without acting on the basis of the height of the protruding height, and the other knitting needle is needle by a predetermined return amount. A roll knitting machine for knitting a tubular knitted fabric comprising a returning guide cam acting on the driving butt to return to the bed gap side.

Further, in the present invention, the needle needle is provided with a needle bed gap side butt at a position closer to the needle bed gap than the drive butt.

The cam system is provided to be in contact with a path through which the needle bed gap side butt passes during the movement in the reverse direction, and acts on the needle bed gap side butt of the knitting needle at the end portion of the knitting width, by an amount less than the return amount. And a needle bed gap side guide cam for returning the knitting needle of the end portion to the needle bed gap side.

In addition, in the present invention, the needle point system,

A pin pin is provided at the end of each needle bed, and whether or not the driving butt of the single needle is projected from the needle groove is formed in the recess formed on the outer circumferential surface. It includes a pre-drum drum to control by mounting whether or not to block the recess,

The pin needle has a length corresponding to the number of knitting needles in the knitting width, and at a portion corresponding to the knitting needle at the end of the knitting width, the height of blocking the recess is lower than that corresponding to other knitting needles in the knitting width. It is characterized by having a shape.

According to the present invention, a drive butt of a single needle accommodated in the needle groove of each needle bed is selectively driven by a cam system mounted on the carriage. For the needle needle selected to protrude from the needle groove by the needle needle system, the stitch forming operation is performed during the movement in the forward direction that is different for each needle bed, and the stitch forming operation is performed during the reverse movement. Do not do it. The knitted fabric knitted by each needle bed is connected in the both ends of the knitting width, and becomes cylindrical. The needle tip system makes the height at which the driving butt of the knitting needle protrudes from the needle groove at the end of the knitting width lower than the other knitting needles in the knitting width. The return guide cam is also mounted on the carriage. The return guide cam is disposed in a path through which the driving butt passes during the movement in the reverse direction. The return guide cam passes through the needle butt against the driving butt of the knitting needle at the end of the knitting width based on the height at which the driving butt protrudes from the needle groove. Return by the amount of return. The knitting needle of the knitted width end portion joining the end stitch is pulled out to the needle bed gap side at the time of stitch formation in the opposite needle bed without returning to the needle bed gap side by the action of the returning guide cam and returned to the needle bed gap side. . That is, the knitting needle for joining the end stitches is expected to be drawn out to the needle bed gap side at the formation of the stitch in the opposite needle bed, and does not return to the needle bed gap side in the return guide cam. The stitches joining the end stitches are drawn out to the needle bed gap side by the formation of stitches in opposite needle beds, and the other stitches in the knitting width are returned to the needle bed gap side by a returning guide cam so that the stitches in the knit widths are joined. Since the size of is also provided, it is possible to avoid that the stitches of the cylindrical knitted fabric are not provided and to prevent the occurrence of stitch breakage at the boundary portion. In the needle tip system, it is only necessary to lower the height at which the driving butt protrudes from the needle groove in the needle needle serving as the end portion of the knitting width, so that the addition of a new mechanism can be avoided as much as possible.

According to the present invention, the knitting needle at the end portion is also returned to the needle bed gap side with a smaller amount of return than the knitting needle at the other portion. Even when the end stitch is pulled to the opposite needle bed side and the amount of return is small, the knitting needle for joining the end stitch is returned to the needle bed gap side in the same way as the other knitting needles within the knitting width, so that the knitted fabric is easily lowered from the needle bed gap. It can be done.

In addition, according to the present invention, the height of the driving butt of the knitting needle that joins the end stitch at the end of the knitting width is lower than the other knitting needles in the knitting width by simply changing the shape of the needle tip pin mounted to the needle needle drum. can do.

In the present invention, when knitting a cylindrical knitted fabric, the end stitch at the end of the knitting width is prevented from being dragged at the start of knitting in the opposite needle bed to become smaller than the other stitches in the knitting width. In order to do this, the knitting needles 11 joining the end stitches do not return in the reverse direction, or form a difference so that the amount of return is smaller than that of the other knitting needles 11. Regarding each needle bed or cam system, the height is described on the basis of the bottom surface of the needle groove, and the needles are placed in the direction close to the needle bed gap. The direction of falling from the bed gap is described below.

Example 1

Fig. 1 is a perspective view showing a schematic configuration of a cam system used in a flat knitting machine 21 for knitting a cylindrical knitted fabric according to the first embodiment of the present invention. For convenience of explanation, the needle bed gap side butt 12a and the drive on the cam plate 2a on one side, for example, the front needle bed side, are driven. Passing paths 12aFT and 13aFT in the forward directions 12aF and 13aF in the butt 13a, and passing paths 22RH and 23R in the reverse directions 22R and 23R. 22RL; 23RH, 23RL) at the same time.

In the cylindrical knitting fabric knitting machine 21, a jack guide cam is provided as the return guide cam of the present invention on the side away from the needle bed gap 10 than the center cam 3; 25) Install. The jack guide cam 25 is arranged to be in contact with the passages 23RH and 23RL through which the driving butt 13a of the jack 13 passes in the reverse direction 23R. In the passages 23RH and 23RL, a difference of ΔL occurs as the amount of return of the knitting needle 11 after the passage of the jack guide cam 25. In order to generate this difference, a difference in height is formed in the amount of protrusion from the needle groove of the drive butt 13a, and the jack plate cam 25 of the cam plate 2a is formed. The height from the surface is made lower than the center cam 3 or the like. As shown by the solid line, the upper edge 25a of the jack guide cam 25 returns only the driving butt 13a that protrudes high, and the driving butt 13a that protrudes low as shown by the broken line does not return. Pass it through. In FIG. 6, the upper edge 6a of the bridge cam 6 has advanced to the needle bed gap 10 side in response to the return amount ΔL, but in FIG. The upper edge 26a does not extend. When the pass paths 23RH and 23RL are determined depending on the height of the protrusion amount in the reverse direction 23R of the drive butt 13a, the pass paths 22RH and 22RH in the reverse direction 22R of the needle bed gap side butt 12a are determined. 22RL) is also determined.

Fig. 2 shows a state in which a difference is made in the amount of return by the jack guide cam 25 by a knitting needle which combines the end stitch with the knitting machine 21 for knitting a cylindrical knit fabric and another knitting needle. Fig. 2 (a) schematically shows a knitting state near the end stitch. 2 (b) shows a configuration for selecting a needle.

In Fig. 2 (a), the knitted fabric on one side, for example, the front needle bed side, is knitted to the end of the knitting width with the center 10a of the needle bed gap interposed therebetween. The state just before starting knitting from the knitting width beginning of the knitting fabric on the back needle bed side is shown. On the rear needle bed side, the needle bed gap side butt 12a and the driving butt (12aF, 13aF) in the forward direction 12aF, 13aF in the cam system of FIG. 1 to form stitches sequentially from the starting needle 11a to the other needle 1lb. Guidance in 13a) is made. On the front needle bed side, the needle bed gap side butt 12a and the drive butt 13a are guided in the reverse directions 22R and 23R in Fig. 1, respectively. The terminal needle 11c is not returned along the pass paths 22RL and 23RL, while for the other needle needle 1lb, ΔL is returned along the passage paths 22RH and 23RH. On the front needle bed side, the knitting butt 13a is inserted into the stitch cam 5 by knitting in the forward directions 12aF and 13aF, and the knitting yarn supplied from the yarn feed opening 30 ( 31 forms a stitch 32 and an end stitch 33. In the end stitch 33, which is a stitch formed by the end knitting needle 11c, the knitting needle 31 is inserted when the stitch is formed by the knitting needle 11a at the beginning of the rear needle bed, and the knitting needle 11c is formed. It becomes small according to the position drawn out to the needle bed gap side. If the end stitch 33 is dragged so that the knitting needle 11c is drawn out to the needle bed gap side by ΔL in advance, the knitting needle 11c does not return. The other needle needle 1lb is returned by the jack guide cam 25 by the return amount ΔL and is in a state indicated by broken lines. Since the end stitch 33 is expected to be dragged in advance, the difference between the return amount of the other stitches 32 is formed and the difference ΔL is formed. Therefore, after knitting in the rear needle bed, the stitches of the front needle bed (1lb, 11c) It is possible to have a size of the stitch to be bonded by.

In Fig. 2 (b), the needle pin 35 used for needle needle in the needle needle mechanism as disclosed in Patent Literature 2 is processed, and a needle needle drum is processed. (36) is used to represent the configuration of the starting needle system which causes the difference in return amount (ΔL). In a normal case, the needle tip pin has the same diameter as the length corresponding to the number of knitting needles 11a, 1lb, and 11c used for knitting in each needle bed, and is used by being mounted on the needle tip drum 36. The process of the needle pin 35 is performed by the needle needle corresponding to the position of the knitting needle 11c forming the end stitch 33, and the lacking part 35a in which the difference DELTA D occurs in diameter is generated. It is made to form. In the present embodiment, the end stitch 33 is joined by one knitting needle 11c at the end of the knitting width. However, when the lacking portion 35a is made long, the number of knitting needles 11c, such as two or three, is increased. You can also do it with a dog.

The needle tip state is equivalent to the case where the needle pin 37 with no missing portion 35a is formed. Fig. 4 (a) shows the pre-needle state in which the lacking part 35a of the needle tip pin 35 acts, and Fig. 4 (b) shows the non-needle state in which the needle tip pins 35 and 37 are not mounted. In the knitting needle 11, the tail end 13b of the jack 13 is coupled to a control jack 38, and is formed by the needle pins 35 and 37 and the needle needle drum 36. It is controlled according to the condition of the needle point.

The needle bed 40 is provided with a plurality of needle plates 42 standing up on a base plate 41 at intervals in the vertical direction with respect to the ground. Needle grooves are formed between the needle plates 42, and the needle needle 11 is accommodated in each needle groove. The needle bed gap side butt 12a of the needle body 12 protrudes from the needle groove, and the drive butt 13a of the jack 13 protrudes if it is pinched by the needle tip system. The cam plate 2a of the carriage shown in FIG. 1 is in contact with the surface side on which the needle bed gap side butt 12a and the drive butt 13a protrude. The end of the needle plate 42 is supported by a needle plate support 43. In a direction perpendicular to the ground, wires 44, 45 and 46 are inserted to position the needle plate 42. As shown in FIG. The bands 47 and 48 are attached to the carriage side surface of the needle groove so that the knitting needle 11 does not separate from the needle groove.

The control jack 38 is capable of rotating displacement about a support shaft 49 extending in the direction perpendicular to the ground. The tail end 13b of the jack 13 is inserted into the pressure lowering portion 38a and the pressure raising portion 38b. The portion where the control jack 38 is supported by the support shaft 49 is pressurized by the control jack pressure plate 50, and the control jack guide is provided between the needle jack 36. jack guide) 51 is inserted. The control jack 38 is pressurized so that the contact portion 38c in contact with the pin needle pins 35 and 37 and the control jack 38 are displaced counterclockwise around the support shaft 49. A spring portion 38d is also formed.

As shown in FIG. 3, the contact portion 38c of the control jack 38 is in contact with the portion different from the lacking portion 35a by the needle pin 35, or the contact portion 38c is connected to the needle pin 37. FIG. In the contacted state, the drive butt 13a protrudes from the needle groove to be in a needle position. As shown in Fig. 4 (a), when the contact portion 38c of the control jack 38 contacts the lacking portion 35a of the needle pin 35, the height at which the drive butt 13a protrudes from the needle groove is shown. Compared to 3, it is lowered by ΔH. The passage paths 23RH and 23RL in the jack guide cam 25 of FIG. 1 are switched according to the height difference ΔH to generate a difference ΔL of the return amount shown in FIG. In Fig. 4 (b), since the driving butt 13a does not protrude from the needle groove, it is not affected by the cam system. In the needle needle 11, the needle bed gap side butt 12a from the needle body 12 always protrudes from the needle groove. However, if the protrusion height of the needle bed gap side butt 12a is formed in two kinds of heights, for example, the heights of the protrusion heights are alternately arranged by the knitting needles 11, the elastic raising cam 9 is provided. Even if it protrudes, a rubber thread can be inserted by filtering the knitting needles 11 one by one by switching the action and non-working.

Example 2
