Description

TECHNICAL FIELD [0001] The present invention relates to a flat knitting machine for knitting tubular knitted fabrics,

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 the shape of a cylinder.

BACKGROUND ART Conventionally, in a weft knitting machine in which at least a pair of needle beds are provided in a state of being opposed to each other in a needle bed gap, socks or gloves are knitted as a tubular knitted fabric (See, for example, Patent Document 1). In a flat knitting machine knitting a sock or glove exclusively, a knitting needle used for knitting is selected by using a needle selection drum (see, for example, Patent Document 2).

Fig. 6 is a view mainly showing a schematic configuration of a flat knitting machine 1 for knitting a tubular knitted fabric used for knitting socks or gloves on a cam system. The flat knitting machine 1 for knitting a tubular knitted fabric has a front needle bed and a back needle bed. Both needle beds are provided with a carriage for performing a knitting operation by selectively driving the knitting needles by reciprocating. The cam system is mounted on a carriage and is divided into cam plates (2a, 2b) which are in contact with front and rear needle beds, and a plurality of cams are respectively disposed. Cams arranged on the cam plates 2a, 2b in contact with the needle beds are substantially equivalent, and corresponding parts are denoted by the same reference numerals. The arrangement of the cams is shown in a state of being viewed from the back side of the cam plates 2a, 2b. A main cam 3, a needle raising cam 4, a stitch cam 5, a bridge cam 6, and the like. A presser cam 7, a needle guide cam 8 and an elastic raising cam 9 capable of protruding and retracting are installed. A needle bed gap 10 is formed in the middle of the two needle beds. The two needle beds opposed to each other on both sides of the needle bed gap 10 are inclined so that the needle bed gap 10 side is higher and the side falling from the needle bed gap 10 is lowered. State.

In each needle bed, needle grooves are formed in the direction of up and down in the drawing. The needle grooves are formed in parallel to each other in the left and right direction of the drawing and are accommodated in the respective needle grooves in such a manner that the knitting needles 11 are capable of sliding displacement to advance and retreat to the needle bed gap 10 . On the left side of the drawing, the knitting needle 11 is shown as a partial structure viewed from the side. The knitting needle 11 includes a needle body 12 and a jack 13. The needle body 12 on the side of the needle bed gap 10 has a needle bed gap side butt 12a projecting from the needle groove to the carriage side and a needle bed gap side butt 12a which is moved back and forth to the needle bed gap 10, A hook 12b and a latch 12c. The jack 13 is provided with a drive butt 13a which projects from the needle groove to the carriage side.

In the flat knitting machine 1 for knitting a tubular knitted fabric, knitting socks or gloves are knitted in a tubular shape by knitting a knitting yarn in a predetermined direction, for example, in a clockwise direction in the drawing. In this case, when the carriage travels in the right direction of the drawing, it becomes a forward direction (forward direction) in the rear needle bed and a reverse direction (reverse direction) in the front needle bed. The stitch forming operation as the knitting needle 11 is performed by moving the drive bolt 13a to the center cam 3, the needle raising cam 4, the stitch cam 5 So as to follow the passage 13aFT. The forward direction 12aF of the needle bed gap side butt 12a draws the passage 12aFT. When the elastic raising cam 9 is actuated, the knitting needle 11 advances to the needle bed gap 10 ahead of the center cam 3 as indicated by the broken line, Elastic yarns can be inserted. When the elastic raising cam 9 is prevented from protruding from the lower needle bed gap side butt 12a, a rubber yarn is inserted into the needle bed gap side butt 12a, The knitting needle 11 can be selected.

On the front needle bed side, the needle bed gap side butt 12a and the driving butt 13a move along the passage paths 12aRT and 13aRT in the reverse directions 12aR and 13aR. On the side of the front needle bed, there is provided a knitting action cam 14 capable of protruding and protruding at the start of knitting, but is sunk when knitting the knitted tubular 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? L.

On the other hand, for example, the carriage on the back needle bed side forms the stitch in the forward direction, and on the other hand, for example, the carriage on the front needle bed side returns the back 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 the stitch in the forward direction. The drive bolt 13a is inserted in the direction away from the needle bed gap 10 by the stitch cam 5 at the end of the drive in the forward direction 13aF. The hook 12b for engaging the formed stitch is also inserted into the needle groove on the needle bed side away from the needle bed gap 10 in a state in which the knitting needle 11 is being pulled. In the needle bed gap 10, a knitted fabric is downwardly moved downward, so that a downward tension is applied to the stitches that are engaged with the hooks 12b of the knitting needles 11 to facilitate knitting a new knitted fabric . When the hook 12b is inserted into the needle bed side, the direction of the tension applied to the stitch to be engaged with the hook 12b, even if the knitted fabric is lowered downward by the needle bed gap 10, The direction is not directed downward. The needle bed gap side butt 12a is returned from the upper edge 6a of the bridge cam 6 at the time of knitting in the reverse direction 12aF so that the hook 12b is brought close to the needle bed gap 10, So that the carriage can be easily lowered from the hook 12b to the needle bed gap 10.

Japanese Patent No. 2631923 Japanese Patent Application Laid-Open No. 10-77557

When the tubular knitted fabric is knitted by the tubular knitted fabric knitting flat knitting machine 1, the knitting needle 11 which is the end of the knitting width in the forward direction side needle bed or the knitting needle 11) is an end stitch. In the end stitch, there is a fear that the knitting yarn is pulled out by the start of knitting in which the carriage is reversed and the needle bed facing in the forward direction is turned, and the size of the stitch becomes small. In Patent Document 1, a knitting needle advancing preventing means (knitting needle advancing preventing means) for restricting the knitting needle 11 from advancing to the needle bed gap 10 side even if the knitting yarn is pulled from the opposite needle bed side is provided.

When the end stitch becomes small, the size of the stitches is increased by increasing the interval between the stitches clogged with the end stitches and the stitches at the boundary connecting the knitted fabric knitted by the needle beds opposed to each other with the needle bed gap 10 therebetween. So that the stitches are broken and the appearance is damaged. However, a new mechanism should be added to the knitting needle prevention means such as Patent Document 1.

It is an object of the present invention to provide a barrel knitting machine for knitting a tubular knitted fabric capable of avoiding the addition of a new mechanism as much as possible and preventing occurrence of stitch breakage at the boundary of the tubular knitted fabric, .

In the present invention, a pair of needle beds are disposed before and after a needle bed gap is interposed therebetween. Each needle bed receives a knitting needle and moves back and forth to the needle bed gap. And needle grooves for guiding a sliding movement in a direction in which the guide grooves are formed,

The driving butt of the knitting needle which is mounted on a carriage reciprocating in the direction in which the needle grooves are formed to be parallel to each other and projected from the needle groove is moved in the different forward direction The knitting needle is advanced to the needle bed gap and retracted to the needle bed so as to perform the stitch forming operation. When the knitting needle is moved in the reverse direction (reverse direction), the stitch forming operation is inhibited. A knitting machine for knitting a tubular knitted fabric having a cam system that can be knitted in the shape of a cylinder by connecting both ends of a knitting width while knitting the knitting machine ),

A knitting needle in a knitting width used for knitting a knitted fabric in each needle bed is selected so that a driving butt protrudes from a needle groove and a protruding height is made lower than other knitting needles in a knitting width of the knitting width end portion, (Selection system)

And the other knitted fabric is passed through the knitting needle of the needle portion not acting on the driving butt of the knitting needle of the end portion on the basis of the height of the protruded portion, And a return guide cam acting on the drive button to return to the bed gap side.

In the present invention, the knitting needle is provided with a needle bed gap side butt at a position closer to the needle bed gap than the driving butt,

The cam system is provided with a cam groove which is provided so as to abut the path through which the needle bed gap side butts pass during the movement in the reverse direction and acts on the needle bed gap side butts of the knitting needle of the knitting width end portion, And a needle bed gap side guide cam for returning the needle of the end portion to the needle bed gap side.

Further, in the present invention,

The needle pin is provided on the tail end side of each needle bed so as to determine whether or not the drive butt of the needle is projected from the needle groove on the basis of a selection pin formed on a concave portion formed on the outer circumferential surface, And a needle drum for controlling whether the concave portion is blocked or not,

Wherein the needle point has a length corresponding to the number of knitting needles in the knitting width and wherein a height of the concave portion at a portion corresponding to the knitting needle of the knitting width end portion is lower than a portion corresponding to another knitting needle in the knitting width Shape.

According to the present invention, the drive button of the knitting needle accommodated in the needle groove of each needle bed is selectively driven by the cam system mounted on the carriage. The knitting needle selected so that the driving button is projected from the needle groove by the needle stitching system allows the stitch forming operation to be performed when the knitting needle is moved in the forward direction which is different from each other in each needle bed and the stitch forming operation Do not. The knitting fabrics knitted in each needle bed are connected at both ends of the knitting width to form a tubular shape. In the needle selection system, the height at which the driving butt of the knitting needle protrudes from the needle groove in the end portion of the knitting width is made lower than the other knitting needles in the knitting width. The carriage also has a guide cam for returning. The returning guide cam is disposed in a path through which the drive button passes when the guide cam is moved in the reverse direction. The returning guide cam passes through the knitting needle without acting on the driving butt of the knitting needle at the end portion of the knitting width on the basis of the height at which the driving butt protrudes from the needle groove and acts on the driving butt of the other knitting needle, The amount of return is returned by the amount. The knitting needle of the knitting width end portion for joining the end stitches is pulled toward the needle bed gap side and returns to the needle bed gap side when stitches are formed on the opposite needle bed without being returned to the needle bed gap side by the action of the returning guide cam . That is, the knitting needle that combines the end stitches is predicted to be pulled out toward the needle bed gap side at the time of stitch formation in the opposite needle bed, and is not returned to the needle bed gap side in the returning guide cam. The knitting needle for engaging the end stitches is pulled out toward the needle bed gap side by the stitch formation in the opposing needle bed and the other knitting needles in the knitting width are returned to the needle bed gap side by the returning guide cam, It is possible to avoid the stitches of the tubular knitted fabric from being provided and to prevent the stitch breakage at the boundary portion from being generated. In the needle selection system, the height at which the driving butt protrudes from the needle groove in the knitting needle serving as the end portion of the knitting width can be reduced, so that 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 if the end stitch is pulled toward the opposed needle bed side and the amount of the backward stitch is small, the knitting needle for joining the end stitch is returned to the needle bed gap side in the same manner as other knitting needles in the knitting width so that the knitted fabric can be easily lowered from the needle bed gap .

According to the present invention, only by changing the shape of the needle placed on the needle bar, the height at which the drive button of the knitting needle coupling the end stitch at the end of the knitting width protrudes from the needle groove is lower can do.
