Definitions
- the present invention relates to a compound needle used for a knitting machine such as a flat knitting machine or a circular knitting machine, and more particularly to a compound needle in which two blades of a slider are housed in a blade groove provided in a needle body so as to be able to move forward and backward.
- Patent Literature 1 Japanese Patent No. 29646323 discloses a composite needle in which a needle body is provided with a blade groove and two slider blades are accommodated in a forward and backward direction.
- a slider is provided at the tip of the two blades of the slider, and the tongue closes the hook at the tip of the needle body when the slider advances, and when the slider further advances, the tongue moves over the hook and transfers, etc. The operation of is performed.
- two blades are stacked and housed in the longitudinal groove provided in the slider jack, and the pad of the slider jack is operated to move the blade forward and backward. Attach the base end of the needle body to the needle jack, and operate the needle body with the pad of this jack.
- a bulge is provided on one of the two blades at a position in the long groove of the slider jack, and the bulge is formed on the side of the needle groove of the needle bed. Contact. This rubbing resistance prevents the delusion of the slider.
- Patent Document 2 (WO 0 1/3 1 1 0 2 A 1) describes that the sliding resistance of the compound needle when it advances beyond the hook of the needle body, and that the blade is pushed right and left by the hook Considering the overhang between the blades.
- Patent Document 2 proposes that a partition is provided in a blade groove of a needle main body, and two blades are housed on the left and right sides of the partition. As a result, the two blades are not spread out at a large angle when they move forward beyond the hook, but are spread out at a small angle by the bulkhead to reduce the left and right overhang. Also, since there is a gap between the blades for the partition, The sliding resistance between the blade and the blade is reduced.
- the partition guides the two blades and also serves to scrape fiber debris brought in between the blades.
- the compound needle of Patent Document 2 there is a gap between the two blades that have advanced from the blade groove.
- lateral force may be applied to the blade from the stitch.
- this force is applied to the blade because the stitches are pulled in the horizontal direction. This force may cause the blade to warp, fail to catch the hook between the blades, and cause troubles such as the two blades approaching one side of the hook. This causes an organizational error.
- forward and backward-a direction parallel to the needle groove of the dollar bed the movement toward the ostium between the needle beds is forward, and simply retreating or retreating from the ostium is referred to as backward or backward. That.
- the direction parallel to the longitudinal direction of the needle bed that is, the direction perpendicular to the longitudinal direction (forward and backward movement direction) of the composite needle, and parallel to the surface of the needle bed is the left-right direction.
- the distal end is the end on the tooth side of each member, and the proximal end is the end on the side far from the tooth opening.
- Anterior Z posterior side near the ostium / rear side far from the ostium. Summary of the Invention
- the object of the present invention is to center the left and right blades on the hook by the partition wall, to ensure that the blade catches the hook even when a force from the stitch is applied, and to compare the blade friction in the blade groove. (Claims 1 to 3). Means for solving the problem
- the present invention provides a needle groove having a hook at a tip thereof with a blade groove having a partition wall.
- the two blades have a shape in which the tips are opened to the left and right, and the rear thereof, for example, slightly backward, is bent inward,
- the thickness of the partition wall is made non-uniform along the longitudinal direction, the thickness is relatively thick at the tip end side of the blade groove, and the wall portion is relatively thin or the partition wall is cut off. (Claim 1).
- the partition wall is made relatively thin at the rear part (claim 2).
- the bent portion comes into contact with a thin portion or a notch of the partition wall (claim 3).
- the tip of the blade may be located at the position of the thick portion of the partition wall, or at the position of the thin portion or the notch. In the embodiment, the tip of the blade is located at the boundary between the thick portion and the thin portion.
- the blade when the blade advances from the blade groove, the blade is centered on the partition wall.
- the bent portions at the rear of the blade tip for example, slightly behind the blade tip, come into contact with each other and endure with the rigidity of two blades. Therefore, the hook can be reliably caught in the opening at the tip of the blade. If the thickness of the partition wall is constant when the blade retreats into the blade groove, the bent portion is expanded by the partition wall, and the tip of the blade further expands, so that friction with the blade groove separation wall increases.
- FIG. 1 is a diagram showing a main part of a composite needle of an embodiment from two directions, that is, a plan view and a side view with a partially notched portion.
- FIG. 2 is an end view showing cross sections at four points (a) to (d) of the composite needle of FIG.
- FIG. 3 is a plan view of a main part of the blade of the composite needle of FIG.
- FIG. 4 is a plan view showing a main part of the compound needle of FIG. 1 in a state where the blade has begun to advance from a blade groove toward a hook.
- FIG. 5 is a plan view showing a main part of the compound needle of FIG. 1 with the blade further advanced beyond the hook.
- 1 to 5 show examples.
- 2 is a compound needle
- 4 is a needle body
- a hook 6 is provided at the tip.
- the portion of the needle body 4 behind the hook 6 may be referred to as a needle stem or shank.
- Reference numerals 8 and 8 denote a pair of blade grooves which are provided at the position of the needle stem and are divided into right and left by a central partition wall 9.
- the blade groove 8 and the partition 9 are symmetrical along the longitudinal center line of the needle body 4. Note that, in a plan view of FIG. 1, a guide 25 described later is cut away.
- the bulkhead 9 is made up of three parts: a thick part 10 at the tip, a thin part 11 at the center of the bulkhead 9 at the rear, and a thick part 10 b at the rear end. This portion may be included in the thin portion 11 without providing the portion 10b.
- the boundary line 13 between the thick portions 10 and 10b and the thin portion 11 and the bottom portion 12 of the blade groove are shown by broken lines in side view in FIG. Between the thick portion 10 on the tip side of the partition wall 9 and the thin portion 11 on the rear side, the boundary line 13 is obliquely arranged from the lower rear to the upper front of the blade groove 8. For this reason, at the position of the cut surface (c) in FIG.
- the thickness of the partition wall becomes uneven above and below the blade groove 8, and becomes thicker at the bottom side and thinner at the upper side.
- the thickness of the partition wall is made uniform above and below the blade groove 8, and the thick part 10
- the thickness of the partition wall may be changed in a tapered shape in the front-rear direction from the thin portion 11 to the thin portion 11. Also, the thickness of the partition wall should be Then, it may be changed stepwise.
- FIG. 14 and 14 are a pair of blades, and as shown in a side view in FIG. 1, are integrated with a rear slider 26 and a main body 26 to constitute a slider of the composite needle 2.
- FIG. 1 shows a state where the blades 14, 14 have receded into the blade grooves 8, 8.
- a tanda 16 At the tip of the blade is a tanda 16, and the bottom 17 of the blade is shown by a broken line in the side view of FIG. 1.
- Blades 14 and 14 have their ends slightly open to the left and right to form openings 18 as shown in Figs.
- blades 14 and 14 are elastically bent behind and come into contact with each other. There is a bend 19. However, the blades 14 and 14 do not need to be in contact with each other at the bent portion 19, for example, there is a small gap between the blades 14 and 14 at the bent portion 19, and the interval between the blades at the bent portion 19 is small. It only has to be narrower than other parts.
- Blades 14 and 14 meet at bend 19, 20 is the gap between blades 14 and 14 behind bend 19, and blades 14 and 14 are located at the upper rear of bend 19.
- 14 is expanded to form an expanded portion 22. Since the blades 14 and 14 come into contact with each other at the position of the bent portion 19 or have a minimum interval, the sliding resistance between the blade 14 and the partition wall 9 or the blade groove 8 is reduced at the position of the bent portion 19. Will be the largest.
- a guide surface 24 provided on a lower surface of the guide 25 shown in a side view in FIG. 1 guides the expanded portion 22 so that the blade 14 sinks into the blade groove 8 when retracted. I do.
- FIGS. 2A to 2D are enlarged views of the cut surface of the needle body 4 along the cut surfaces (a) to (d) of FIG.
- the depth of the blade groove 8 becomes deeper from the thick part 10 at the tip of the partition wall to the thin part 11 and the partition wall is thick at the positions (a) and (b), and at the position (c).
- the upper part of the bulkhead is thin and the lower part is thick.
- the thickness from the top to the bottom of the partition is thin.
- Fig. 3 shows one blade 14 alone
- Fig. 4 shows blades 14 and 14.
- This shows a state in which the robot has advanced from the inside of the groove to just before the hook 6.
- the ends of the blades 14 and 14 open to the left and right outside to form an opening 18, and the front part of the rear expanding part 22 is a tinker 16, which closes the mouth of the hook 6, transfers or knocks over I keep a loop for things like.
- the tongue 16 has the aforementioned bent portion 19 at the rear of the opening 18, and the bent portion 19 is bent inward from a line inside the longitudinal direction of the blade 14 shown by a chain line in FIG.
- the blades 14 and 14 are in elastic contact with this portion.
- the left-right lateral force from this stitch becomes a problem.
- this stitch is a stitch on the left and right ends of the knitted fabric ⁇ a stitch that has been racked, etc. Have joined.
- this force is received by one blade 14, the blade may warp, and the two blades may move to one side of the hook 6, and the hook 6 may not be able to be caught in the opening 18.
- the rigidity of the blade as a whole is doubled, for example, as compared to the case of one blade, and the blade rigidity depends on the thread tension.
- FIG. 5 shows a state in which the blades 14 and 14 are further advanced, and the tiner 16 has passed over the hook 6.
- the blades 14 and 14 are centered at the thick portion 10 of the partition wall 9. Also, against the force applied to the blades 14 and 14 from the stitches, the two blades 14 and 14 are brought into contact at the bent portions 19 and 19 to reduce deformation such as warpage of the blade. . As a result, the opening 18 can reliably catch the hook 6, and there is no possibility that the blades 14, 14 may collide with the hook 6 or move to one side of the hook 6.
- the thin portion 11 may be notched. However, it is more reliable to provide the blade with the thinner part. 1 If the thickness of the hook 6 is tapered from the base to the head (the tip of the hook), the tongue 1 By devising the shape of blades 14 and 14 in 6, The sliding resistance between the hook 6 and the tanda 16 can be reduced.
- the portion where the shape of the blade is changed is, for example, a portion of the tunders 16 and 16, particularly a portion within the tundas 16 and 16 behind the bent portions 19 and 19.
- the lower part of the blades 14, 14 is bent left or right outward or twisted outward so that the distance between the blades 14, 14 gradually increases from the top of the blade to the bottom (bottom). Then, the upper portions of the blades 14, 14 are in contact with each other at the bent portions 19, 19, for example, and a gap is formed at the lower portion, and the sliding resistance is reduced by fitting to the taper of the hook 6. Increasing the spacing between the blades at the lower portion of the bent portion 19 to reduce the sliding resistance with the tapered and tapered hook is also effective when the partition 9 is not provided in the blade groove.
