Abstract

The utility model provides a flat knitting machine with movable sinkers, which can prevent knitting yarns from biting into hooks of unused knitting needles in 1X1 draw knitting and can prevent blades for loop transfer from being damaged even if the needle pitch is small. The first yarn guide spacer and the second yarn guide spacer guide knitting yarn to a hook of a first knitting needle which is withdrawn from the needle bed gap at a yarn guide portion provided at a tip end facing the needle bed gap. The shielding portion of the second yarn guide spacer does not guide the knitting yarn to the hook of the second knitting needle resting on the needle bed. The hook of the second knitting needle which is not used in 1X1 draw knitting can be prevented from biting into the knitting yarn. The second yarn guide spacer is configured such that a lower hem portion, which is a lower end of the shielding portion, is lower than a tip portion of a transfer blade provided to a needle bar of the second knitting needle. Since the yarn guide portion does not enter the inside, breakage of the blade can be prevented.

Description

Flat knitting machine with movable sinker

Technical Field

The present utility model relates to a flat knitting machine including movable sinkers used for 1X1 draw knitting.

Background

Conventionally, in a flat knitting machine having at least a pair of front and rear needle beds facing each other, knitting is also performed in which knitting needles used for knitting a knitted fabric belonging to one needle bed and knitting needles not used for knitting the knitted fabric are alternately arranged in advance in a longitudinal direction of the needle bed at 1X1 draw-down needles. The unused knitting needle is used for transfer and the like in knitting a knitted fabric belonging to the other needle bed. The tubular knitted fabric can be knitted by connecting both ends of the knitting width while knitting the knitted fabric belonging to one needle bed in one of the longitudinal directions and knitting the knitted fabric belonging to the other needle bed in the other of the longitudinal directions.

The knitting needle of the flat knitting machine advances and retreats with respect to the needle bed gap along the needle grooves arranged in the needle bed, and loops are formed. The loop is formed by a needle loop in which a knitting needle advancing and retreating relative to the tooth opening is introduced into a knitting yarn and a sinker loop generated by the knitting yarn being caught by a sinker facing the tooth opening. The needle grooves are formed between plate-like needle plates arranged on the base plate of the needle bed. When the sinker is movable, the old stitch separated from the knitting needle when a new stitch is formed can be pressed down to the mesh (for example, refer to patent document 1). In patent document 1, a movable sinker is arranged on one side of 1 knitting needle between needle plates. The movable sinker is housed in a thin portion formed by processing the needle plate in the thickness direction of the needle bed in the longitudinal direction. In the flat knitting machine including such movable sinkers, the respective members are arranged in the order of stacking the needle plate, the movable sinkers, the carrier spacers, the needle spacers, and the needle plate along the longitudinal direction of the needle bed.

Patent document 1: japanese patent No. 4016028

In order to weave a fine stitch with a flat knitting machine, a fine knitting yarn is required. The flat knitting machine needs to reduce the thickness of each member and the pitch of the knitting needles along the longitudinal direction of the needle bed. In a flat knitting machine with a small stitch length, even if the plate thickness of each member is reduced, it is difficult to arrange the members on a space surface. When each member such as a knitting needle is thinned, rigidity is lowered. In addition, when the knitting needle enters the tooth mouth and rises, the support is lost or even if there is a support, the rigidity is lowered. When the rigidity of the knitting needle itself is low, the knitting needle rising up the tooth opening is liable to fall down. In order to be able to perform transfer, a transfer blade needs to be provided on the stem side of the knitting needle. As the knitting needle rises, the blade also rises, and when the knitting needle falls down, the lower hem portion of the carrier spacer and the like enter the inside of the blade, and the blade may be broken. In addition, a hook for preventing the knitting yarn from erroneously biting into a knitting needle which is not used in 1X1 draw knitting is also required.

Detailed Description

Hereinafter, fig. 1 to 6 show a structure of a flatbed knitting machine 1 provided with a movable sinker 6 as an embodiment of the present utility model. Corresponding parts in the drawings are denoted by the same reference numerals, and duplicate description may be omitted. For convenience of explanation, a portion not shown in the drawings is present. In the following description, the direction of advancing and retracting the knitting needle may be the forward direction toward the needle bed gap, the backward direction away from the needle bed gap, the upward direction toward the opening in the needle bed gap, and the downward direction toward the bottom.

Examples (example)

Fig. 1 schematically shows a component arrangement on a needle bed 2 of a flat knitting machine 1 provided with a movable sinker as an embodiment of the present utility model. The flat knitting machine 1 provided with movable sinkers is configured such that first knitting needles 3 used for knitting a knitted fabric belonging to the needle bed 2 and second knitting needles 4 not used are alternately arranged in a longitudinal direction of the needle bed 2, which is a lateral direction in the drawing, and used exclusively for 1X1 draw knitting. If knitting the knitted fabric belonging to each of the front and rear needle beds 2 facing each other with the needle bed gap 5 therebetween is performed so that the knitted fabric belonging to the front and rear needle beds 2 is connected to both sides of the knitting width while switching the knitting direction in the front and rear directions, the tubular knitted fabric can be knitted. The 1X1 draw knitting can perform knitting accompanied by transfer and stitch-forming knitting of the back stitch by the unused second knitting needles 4 of the opposing needle beds 2. In this example, the density of the knitting needles was set to 24 per 1 inch (25.4 mm). Therefore, the member disposed on the needle bed 2 is often a member having a thickness of 1mm or less in the longitudinal direction of the needle bed 2, but the thickness is exaggerated for convenience of illustration.

In the flat knitting machine 1 provided with the movable sinker, the first knitting needle 3 and the second knitting needle 4 are substantially identical. The first knitting needle 3 and the second knitting needle 4 have hooks 3a and 4a at the front end facing the needle bed gap 5, and blades 3b and 4b for transferring loops at the sides of the rear needle bar farther from the base end side than the hooks 3a and 4 a. The height of the needle bar increases rearward from the shoulders 3c, 4c near the middle of the blades 3b, 4b. In the flatbed knitting machine 1 provided with movable sinkers according to the present embodiment, the movable sinkers 6 and the control claws 7 are provided every 1, that is, the movable sinkers 6 are disposed only on the side of the blade 3b of the first knitting needle 3 and are not disposed on the side without the blade 3 b. In the second knitting needle 4, the movable sinker 6 is disposed on the side where the blade 4b is not provided, and is not disposed on the blade 4b side. The control claw 7 switches the position where the tail of the movable sinker 6 is locked by swinging to change the sinker stroke. The wire 8, which is the axis of the swing of the control pawl 7, is inserted along the longitudinal direction of the needle bed 2. The needle bed 2 alternately disposes a first needle plate 21 and a second needle plate 22 on a substrate 20. The first needle plate 21 and the second needle plate 22 are needle grooves therebetween, and alternately accommodate the first knitting needles 3 and the second knitting needles 4. The rear side of the first needle plate 21 serves as a space for accommodating the control claw 7, and the wire 8 is supported by a wire supporting portion 22a provided on the rear side of the second needle plate 22. The movable sinker 6 may be configured so as not to switch the sinker stroke. If no switching is performed, the control pawl 7 is not required. First and second carrier spacers 31 and 32 are alternately arranged between the first and second knitting needles 3 and 4 and the first and second needle plates 21 and 22.

For each member, for example, at least the first needle plate 21, the movable sinker 6, the first carrier spacer 31, the second knitting needle 4, the second needle plate 22, and the second carrier spacer 32 are stacked between the first knitting needle 3 and the next adjacent first knitting needle 3 from one side in the longitudinal direction to the other side in the right direction in the figure.

Fig. 2 shows a structure obtained by arranging the components of fig. 1 as viewed from the tooth mouth 5 side. Fig. 3 shows the shape of the first and second yarn guide spacers 31 and 32 shown in fig. 1. Fig. 4 shows the shape of the first needle plate 21 and the second needle plate 22 shown in fig. 1. A first carrier spacer 31 is arranged between the first needle plate 21 and the second knitting needle 4. A second carrier spacer 32 is arranged between the second needle plate 22 and the first knitting needle 3. The first and second yarn guide spacers 31 and 32 have yarn guide portions 31a and 32a at the tip end facing the tooth mouth 5. The yarn carrier sections 31a and 32a guide knitting yarns to hooks 3a and 4a of the first knitting needle 3 and the second knitting needle 4 which are withdrawn from the needle bed gap 5 to the needle bed 2.

The first needle plate 21 is disposed between the first knitting needle 3 and the second knitting needle 4, and includes a sinker supporting portion 21c and a thin portion 21a for accommodating the movable sinker 6, and the rear portion side of the thin portion 21a has a shape facing the space accommodating the control claw 7. The second needle plate 22 is disposed between the second knitting needles 4 adjacent to the movable sinker 6 accommodated in the thin portion 21a of the first needle plate 21 and the first knitting needles 3 adjacent to the second knitting needles 4, and a wire supporting portion 22a for supporting the wire 8 serving as the swing shaft of the control claw 7 is provided in a portion corresponding to a space facing the rear portion side of the thin portion 21a of the first needle plate 21. In addition, the second needle plate 22 of the present embodiment has a distal end portion 22b which lacks the sinker supporting portion 21c and its peripheral portion and extends toward the tooth opening 5, in addition to a portion corresponding to the thin wall portion 21a of the first needle plate 21. The shape of the second needle plate 22 can be enlarged because the missing portion becomes large. The first needle plate 21 also has a distal end portion 21b. The distal ends 21b, 22b are supported from the side by the first knitting needle 3 and the second knitting needle 4 that enter the needle bed gap 5, and can be reinforced so as to be less likely to vibrate.

The first carrier spacer 31 has a projection 31b capable of holding the control pawl 7 at least temporarily on the trailing end side away from the needle bed gap 5, and a shoulder guide portion 31c on the tip end side facing the needle bed gap 5, and the shoulder guide portion 31c guides the second knitting needle 4 by being biased to bend toward the unused second knitting needle 4 side while being brought into sliding contact with the shoulder 4c of the needle bar of the second knitting needle 4 that enters the needle bed gap 5 and rises by transferring, looping, or the like. The second carrier spacer 32 has a shielding portion 32b and a lower hem portion 32d on the tip end side facing the tooth opening 5. The shielding portion 32b serves as a wall for shielding the latch closing the hook 4a of the second knitting needle to prevent the knitting yarn from entering. In the use of the second knitting needle 4 in the transfer, the reverse stitch knitting, and the like, although the first knitting needle 3 is stopped, the shielding portion 32b also serves as a wall for preventing the knitting yarn from entering the stopped first knitting needle 3. The lower hem portion 32d is a lower end of the shielding portion 32b, and protrudes in a direction away from the needle bed gap 5 to a position lower than a tip of the transfer blade 4b provided in the needle bar of the second knitting needle 4. Even if the second knitting needle 4 is lifted up so as to enter the needle bed gap 5, the lower hem portion 32d does not enter the inside of the blade 4b, and therefore breakage of the blade 4b can be prevented. The second carrier spacer 32 has a shoulder guide portion 32c on the tip end side facing the needle bed gap 5, and the shoulder guide portion 32c is bent by being biased toward the second knitting needle 4 side, and guides the second carrier spacer while being in sliding contact with the shoulder portion 4c of the second knitting needle 4 entering the needle bed gap 5. In the present embodiment, the shoulder guide portions 31c and 32c are provided on both the first carrier spacer 31 and the second carrier spacer 32, and the second knitting needle 4 is sandwiched therebetween. The shoulder guide portions 31c, 32c guiding the second knitting needle 4 while sliding in contact with the shoulder portion of the second knitting needle 4 entering the needle bed gap 5 can strengthen the rigidity of the second knitting needle 4. The second carrier spacer 32 has a shoulder sliding contact portion 32e on the other side in the longitudinal direction below the shoulder guide portion 32c, and the shoulder sliding contact portion 32e guides the first knitting needle 3 while sliding in contact with the shoulder portion 3c of the needle bar when the first knitting needle 3 enters the needle bed gap 5. The shoulder sliding contact portion 32e that is in sliding contact with the shoulder portion 3c can prevent vibration and stabilize knitting even when the first knitting needle 3 is lifted up toward the needle bed gap 5.

The first carrier spacer 31 has a first knitting yarn fall-off prevention portion 31d and a second knitting yarn fall-off prevention portion 31e below the carrier portion 31a, the first knitting yarn fall-off prevention portion 31d preventing the knitting yarn from falling off to the sinker of the needle bed 2 provided on the side of one adjacent movable sinker 6 in the longitudinal direction, and the second knitting yarn fall-off prevention portion 31e preventing the knitting yarn from falling off to the sinker of the needle bed 2 provided on the side of the next adjacent movable sinker 6 in the other side in the longitudinal direction. The first knitting yarn fall-off prevention portion 31d and the second knitting yarn fall-off prevention portion 31e are connected to each other by an extension portion 31f extending so as to traverse along the bottom surfaces of the two needle grooves. The first drop preventing portion 31d of the first carrier spacer 31 also has a gap 31g between the unused second knitting needles 4 adjacent to the other side in the longitudinal direction. Even the unused second knitting needle 4 may be used for knitting with the facing needle bed 2, and the knitting yarn can be smoothly introduced at the time of use because of the gap. Further, the height of the gap 31g is set in advance at least above the latch of the closing hook 4b. The second carrier spacer 32 does not have a knitted yarn fall-off preventing portion. The lower swing portion 32d provided in the second carrier spacer 32 is supported by the tip end portion 22b of the second needle plate 22, so that the entry into the interior of the transfer blade 4b can be reliably prevented.

Fig. 5 and 6 show the structures around the movable sinker 6 and the second knitting needle 4 and around the first knitting needle 3, respectively, in the flat knitting machine 1 provided with the movable sinker in fig. 1. The first knitting needle 3 moves in the lateral direction in the figure in such a way that the hook 3a advances and retreats with respect to the needle bed gap 5. The second knitting needle 4 is also moved in the same way in the case of use in transfer, looping, etc. Although the movement of these knitting needles is illustrated as horizontal in the drawing, in an actual flat knitting machine, the knitting needles are inclined so that the needle bed gap 5 side becomes higher. The movable sinker 6 has a distal arm 6a, a swing fulcrum portion 6b, and a trailing arm 6c provided at the distal end on the tooth mouth 5 side. The distal arm 6a includes: a knitting yarn hooking portion 6d, wherein the knitting yarn hooking portion 6d is hooked by knitting yarn to form a sinker loop when the coil is formed; and a coil press-fitting portion 6e for pressing the old coil, which is removed from the coil, downward of the tooth 5 when the coil is formed in the coil press-fitting portion 6 e. The movable sinker 6 is accommodated in a thin portion 21a provided in the first needle plate 21, and swings about a swing fulcrum portion 6b supported by the sinker supporting portion 21c so that the tip arm 6a moves forward and backward with respect to the tooth opening 5. The swing of the movable sinker 6 is biased by a spring 9. The spring 9 of the present embodiment is separate from the movable sinker 6, but may be integrated. The sinker stroke in which the coil pressing portion 6e is pressed into the old coil by the urging force of the spring 9 is switched by engagement of the stepped portion 7a of the control claw 7 with the trailing arm 6c of the movable sinker 6. This switching is performed by causing a cam, not shown, mounted on a carriage traveling in the longitudinal direction of the needle bed 2 to act on a butt 7b provided on the control claw 7. The movable sinker 6 is sandwiched between the first needle plate 21 and the first carrier spacer 31, and can be kept in the switching state at least temporarily by the projection 31b provided at the tail of the first carrier spacer 31.
