Definitions

  • the invention relates to a latch needle for a stitch-forming machine, in particular for a knitting machine for producing textile surfaces.
  • latch needles are used in machines, in particular in knitting machines, which are moved back and forth to form the stitches in rapid succession.
  • the tongue provided on a knitting machine needle opens and closes a receiving space for a thread in rapid succession and at high speed. This receiving space is bounded by the needle body and at its one end hook in cooperation with the opening and closing tongue.
  • the tongue beats alternately on the hook in rapid succession, forming the closed position, as well as on the shaft of the latch needle, to form the open position or reserve.
  • the tongue of the latch needle is moved through the loop or half stitch.
  • the tongue speed is highest at the tip of the tongue and decreases with the distance to the pivot point of the tongue on which it is mounted in the knitting machine needle.
  • a state of the art knitting machine needle 1 according to Figure 4, 4a, 5a and Figure 7 at the top 37 of its needle body 2, a trough-like recess 27 and a receiving hopper 15 in the form of an impression.
  • This follows in cross-section substantially a circular arc and is adapted to the back surface 23 of the tongue head 8, which is held by a tongue shaft 9.
  • the tongue shaft 9 merges on both sides on a line 24 in the tongue head 8, which forms the edge of a facet 10, 10 '.
  • the surfaces or facets 10, 10 ' are at an acute angle to each other and connect to the back surface 23 at.
  • the tongue head 9 is symmetrical to the central axis B and has on its side facing the needle body on a width which coincides with the relatively large width C + of the recess ( Figure 4a).
  • This relatively large width C + of the receiving hopper 15 and also the large mass of the tongue head can cause problems because this mass must be moved at high speed between the closing and backing back and forth.
  • the kinetic energy must be destroyed at the receiving hopper 15 for the tongue head. In the open position, this is done by the spring action of the bearing areas of the sheep cheeks, which are also referred to as jaws of the latch needle. This spring action can be achieved by extending the tongue slot or be influenced by an additional, second slot in the latch needle.
  • the machine knitting needle is guided in a needle channel of a needle bed and rests with the bottom of the needle (needle back) on the bottom of the needle channel. This can end in the throat area, ie the area of the receiving funnel of the latch needle.
  • the needle moves well beyond the support area of the needle carrier. In this area, the machine knitting needle is subjected to tensile forces acting in the direction of the needle carrier. These tensile forces are caused by the fabric removal.
  • the fabric withdrawal pulls already knitted goods away from the needles. The goods are held by the needles through half-stitches, which are located on the back of the needle.
  • the pull-off forces on the half-stitches act directly on the needle body, which undergoes its support in the needle carrier.
  • these tensile forces increase, the farther the half-stitches move in the direction of the needle hook.
  • the resulting stresses can lead to Nadelschaftbrüchen.
  • the needles usually break at the receiving hopper or shaping impression, which forms a weak point of the latch needle body and lies approximately at the end of the needle carrier (the so-called knock-off edge) when the knitting machine needle is in the extended position.
  • An on a tongue head according to the prior art adapted form impression which has a corresponding size, promotes this breaking behavior.
  • the needle shaft has a recess, wherein the shape of the recess is formed complementary to the back surface of the tongue head.
  • the recess is formed by removing needle shank material.
  • the contact surface of the tongue head is limited to the existing width of the side walls of the needle shaft, ie the needle shank cheeks, wherein the needle shaft is weakened by the removal of material for the production of the recess. This increases the susceptibility to breakage of the latch needle.
  • latch needle for a stitch-forming machine, said latch needle to show a reduced tendency to needle or tongue fractures.
  • the latch needle according to the invention according to claim 1 meets these expectations. It has at its tongue back at least two first facets, which are arranged divergent as in a conventional latch needle in the tongue longitudinal direction. In addition, two further (second) facets are provided, which are arranged between the existing facets and the back of the tongue. They diverge from the back of the tongue. As a result, the facets are arranged inclined to a plane imaginary by the central axis.
  • the opening direction of the preferably acute angle enclosed by the first facets substantially coincides with the tongue longitudinal direction.
  • the opening direction of the preferably acute angle enclosed by the second facets substantially coincides with a direction which deviates from the tongue longitudinal direction and lies in the median plane.
  • the first two facets are preferably arranged symmetrically to the median plane.
  • the two second facets are preferably also arranged symmetrically to the median plane. These facets can be flat or arched. In this case, a concave curvature is preferred.
  • the facets are at the end of the spoon-shaped Tongue head, arranged at which this connects to the tongue shaft.
  • the tongue shaft has a width which is slightly smaller than the width of the tongue slot, so that the tongue is kept movable in the tongue slot.
  • the tongue head projects beyond the tongue slot and also the hook of the latch needle in its width, in order to ensure the knocking off of the half stitch over the tongue head smoothly.
  • the second facets lead to a weight reduction of the tongue head, which reduces its kinetic energy.
  • the pressure to be provided on the needle body shape impression can be made narrower than before, which reduces the otherwise existing weakening of the needle body at this point.
  • the first two facets form a transition section from the relatively narrow tongue shaft to the broad tongue head.
  • This transition section may partially dive into the tongue slot and / or in the receiving hopper of the needle body.
  • this transition section of the tongue preferably has on each side in each case a first and a second facet. Starting from the flat side of the tongue shaft whose width is first increased by the first, each other a wedge-forming facets until the maximum width of the tongue head is reached.
  • the second, preferably elongated, facet is adjacent to the preferably substantially triangular first facet, thereby reducing the cross-section of the latch head in the transition section of the latch shaft to the latch head.
  • the transition portion of the tongue shaft is in the region of the receiving hopper, which can thus be reduced in size, in particular its width.
  • the second facet is at an obtuse angle arranged to the first facet. Both facets can merge seamlessly into one another, so that the sliding of the stitches over the back of the tongue is not hindered.
  • the transition of the two molding surfaces into each other can be designed, eg rounded, that it is not possible to determine an exact boundary of the two molding surfaces.
  • the facets with rounded edges and edges in the other tongue back can go over.
  • the cross section or the volume of the tongue head is reduced at the portion with which the tongue head dips into the receiving funnel of the sheep cheeks in the open position or touches it.
  • the width of the receiving hopper can be reduced.
  • the needle shank cheek can be formed wider at its top. This leads to a reinforcement of this critical area of the needle body, which otherwise forms a weak point.
  • the shape of the receiving hopper ie the so-called shaping impression
  • the shape corresponds to the shape of the tongue head in the region in which the tongue head rests against surfaces of the shaping impression.
  • the tongue head usually has a curved shape that follows a radius.
  • the receiving hopper merges into the upper side of the sheep cheeks, it can have at least one partial surface. This partial surface is preferably aligned parallel to the second facet of the tongue head.
  • a section through the receiving hopper is then bounded by a curve consisting of an arcuate portion and two straight line sections.
  • a receiving hopper for the tongue head at its lowest point in the center of a bow, such as a circular arc follows, ie is curved and is formed at its ends areal.
  • This receiving hopper can be adapted substantially to the shape of the tongue head in this area.
  • FIG. 1 illustrates a latch needle 1 which has a needle body 2 with a loop-forming part 3, on which end a hook 4 is formed.
  • the hook 4 is provided with a tip 12 which may be rounded at its upper side 18.
  • the needle body 2 has at its stitch-forming part 3 a tongue slot 17 into which a tongue 6 projects with one end 19.
  • the tongue 6 is held in the tongue slot 17 on a bearing device 5 and pivotally mounted.
  • the storage device 5 is z. B. formed by a tongue slot 17 by cross-bearing axis. This bearing axis may be formed in the form of a bearing pin or preferably in the form of a one-piece or multi-part with the needle body 2 seamlessly connected pin.
  • the tongue 6 is pivotally mounted from the closed position shown in Figure 1 on the left side in a reserve, which is illustrated in Figure 1 on the right side.
  • the tongue has a narrow, preferably parallelflankig limited shaft 9, the width of which is slightly smaller than that of the tongue slot 17.
  • the length of the tongue 6 is dimensioned so that it can reach the top 18 of the hook 4 with its end 20 and partially overlaps ,
  • the end 20 is provided on the hook 4 facing side with a recess 21 which forms a trough 22 for receiving at least a portion of the hook 4 according to the embodiment of Figure 1.
  • the trough 22 may correspond to the shape of the top 18 of the hook 4 and be adapted.
  • the latch needle 1, in particular the needle body 2, is held movably in a needle carrier 36.
  • the needle carrier 36 can end approximately at the axial position, where the tongue head 8 cooperates in reserve with the needle body 2.
  • the needle body 2 is supported at this point by the needle carrier 36, in particular when the needle is subjected to the tensile forces F of the fabric take-off.
  • the formation of the end 20 of the tongue 6 is shown in FIGS. 2, 3 and 5.
  • the end 20 includes a back surface 23, which forms the back of a end formed on the tongue 6 spoon.
  • the tip of the spoon marks the end 20 of the tongue 6.
  • Its width exceeds the width of the substantially parallel-flanked tongue shaft 9.
  • the tongue shaft 9, whose width is determined by the distance of its flat sides 7 and 7 'from each other, goes to a line 24 with the Transition region 16 in the tongue head 8 via.
  • the width of the tongue head 8, which is measured perpendicular to the flat sides 7, 7 ', increases continuously from the line 24 in the axial or tongue longitudinal direction progressively. Their maximum width reaches them at the dashed line in Figure 2 and 5 line 25 which intersects the spoon.
  • the (imaginary) line 25 is located approximately in the middle of the tongue head length L, which extends from the line 24 to the end 20 of the reed head 8.
  • the widest point of the tongue head 8 may also be displaced in the direction of the line 24 so that it does not lie in the middle of the tongue head length L.
  • the increase in the width of the tongue head 8 is determined (as shown in FIG. 2) by the first facet 10.
  • the edge of the facet 10 is preferably an isosceles triangle.
  • the facet 10 is preferably flat. It is also possible to make them convex or concave curved.
  • a second facet 11 is formed on the tongue head 8.
  • This facet 11 lies above the receiving hopper 15 of the needle body 2 when the tongue 6 is in reserve.
  • This second facet 11 is an elongated molding surface, which, as can be seen in FIG. 3, is arranged at an obtuse angle ⁇ to the first facet 10.

  • Embodiments are also possible in which the facet 11 extends almost over the entire length of the tongue head. It then extends, starting from the forming surface 10, to the end 20 of the tongue head 8 and then ends at the trough 22, which is close to the tongue head end.
  • FIG. 3 shows an exemplary embodiment in which the tongue head 8 has two first divergent facets 10, 10 ', which in each case intersect the drawing plane oriented transversely to the longitudinal direction of the needle in a line which lies parallel to a plane B which in turn is parallel to the flat sides 7, 7 'of the tongue shaft 9 is arranged.
  • the tongue head 8 has on each side of the plane B in each case a second planar facet 11, 11'.
  • the two facets 11, 11 ' enclose an acute angle ⁇ with one another.
  • the cross-sectional area and the volume of the tongue head 8 are reduced in the transition region 16, with which it cooperates with the receiving hopper 15 or in which it rests in the receiving hopper 15.
  • the arrangement of the facet 11 is selected such that an extension beyond the back surface 23 in the direction of Needle body 2 the tongue slot 17 cuts. Tangents of the facets 11, 11 ', which are applied to the facets in the plane of the drawing, form an intersection point A. This intersection point A preferably lies on the center plane B and varies as a function of the angle ⁇ . The distance between the intersection A and the back 23 of the needle tongue 6 is preferably at least half the thickness of the tongue shaft 9.
  • the receiving hopper 15 is formed by a recess 27 which is adapted to the back surface 23 in the transition region 16 of the reed head 8.
  • the receiving hopper 15 at its lowest point in the vicinity of the median plane B has a curvature which substantially corresponds to the curvature of the adjacent portion of the back surface 23 of the reed head 8.

  • the receiving hopper 15 has, measured transversely to the center plane B, a width C (FIG. 3 a) which is substantially smaller than in the case of a receiving hopper according to the prior art (FIGS. 4, 4 a and 7).
  • the width of the upper sides 32, 32 'of the needle shaft cheeks 30, 30' adjoining the receiving hopper 15 is determined by the size of the chamfer 31, 31 'and the width C of the receiving hopper 15.
  • This width of the top surface 32, 32 ' is significantly larger, at least 1.5 times, compared to the width of a top surface 32 of a prior art needle ( Figures 4, 4a and 7). This increases the stability of the sheep cheeks 30, 30 'in this area and thus the stability of the needle body 2 as a whole.
  • the receiving hopper 15 is produced by a non-cutting machining.
  • material from the region of the needle shaft cheek 30, 30 'in the direction of the tongue slot 17 be relocated.
  • a support surface is created in the receiving hopper 15 above the tongue slot 17.
  • the material displacement can be carried out so that the edges of the protrusions formed on the sheep cheeks 30, 30 'in the region of the center plane B almost touched ( Figure 6).
  • Figure 3a shows the width C of the receiving hopper 15. Between the top 32 and the receiving hopper 15 is a boundary D. Between the top 32 'and the receiving hopper 15 is a limit D'. The width C of the receiving hopper 15 is to be measured from the boundary D to the boundary D '. The width C of the receiving hopper 15 is substantially smaller than in the case of a prior art needle (FIGS. 4, 4a and 7). This is achieved by the arrangement of the partial surface 29, 29 'in the recess 27. The rounding of the receiving hopper 15, which corresponds to the rounding of the back surface 23 of the tongue head 8 in a needle according to the prior art, is interrupted by the partial surfaces 29, 29 '. FIG.
  • 3a shows, by way of example, the imaginary extension of the otherwise uniformly rounded surface of the receiving hopper 15 on the right-hand needle shaft cheek 30. Due to the deviating from the other rounding faces 29, 29 ', the width C of the receiving hopper 15 in comparison to conventional form impressions by two times the distance X be reduced. The distance X is the distance between the boundary D and the end of the receiving hopper 15 without partial surfaces 29, 29 'according to the prior art. By reducing the width C of the receiving hopper 15, the widths of the upper sides 32, 32 'of the needle shank cheeks 30, 30' can be increased by the amount X.
  • a transition 33 is formed between the facet 10 and the facet 11 of the tongue head 8.
  • This transition 33 may be formed as a rounded or smoothed edge, which does not hinder the stitch formation.
  • the transition 33 may also be formed as a surface or other facet. This serves the smooth transition of the facet 10 into the facet 11. A clear boundary between the facets 10 and 11 is then no longer discernible.
  • FIG. 5 shows an alternative embodiment of the facet 11 in a dashed line.
  • This alternative facet 11 extends from the facet 10 almost over the entire length of the reed head 8 and follows its lateral curvature.
  • requirements of the stitch forming process may be taken into account.
  • Figure 6 shows a plan view of the recess 27 of the receiving hopper 15. This can be formed by a forming process from the sheep cheeks 30, 30 'out and two curved surfaces 34, 34' have.
  • the edge of the surface 34 is preferably rounded at the side facing the chamfer 31. This greatly increases the stability of the knitting machine needles in this area as compared to prior art knitting needles, and FIG. The same applies mutually to the forming surface 34 '.
  • the danger the formation of an undesirable weak point due to a corner in the edge of the surface 34, 34 'and the recess 27 is thus significantly reduced.
  • the tongue needle 1 described so far works as follows:
  • the latch needle 1 is moved back and forth in accordance with their longitudinal direction indicated in Figure 1 by an arrow 35.
  • the tongue oscillates continuously between the closed position ( Figure 1 left side) and the reserve ( Figure 1 right side).
  • the recess 21 partially overlaps the hook 4.
  • the hook 4 is released.
  • the facets 11, 11 ' reduce in comparison to a tongue 6 of the same shape, but without such surfaces, the volume of the tongue head 8 and thus the reacted kinetic energy handsomely.
  • the latch needle 1 is reinforced due to the adapted, narrowed shape of the receiving hopper 15 and can better absorb and absorb the kinetic energy. This results in a lower load on the top 18 of the hook 4 and in the region of the recess 27 in reserve of the latch needle 1. This leads to the reduction of the shock acting on the tongue 6 and the needle body 2, which the number of breaks in Area of the tongue shaft 9 and the needle body 2 reduced.
  • the latch needle 1 has a tongue 6, which on its tongue spoon on the side facing away from the hook 4 thereof with at least two facets or forming surfaces 10, 11 is provided. These facets 11, 11 'converging towards the tongue back 23 reduce the volume of the tongue head 8. This makes it possible to reduce the width C of the recess 27, resulting in stabilization of the knitting needle 1 in this area.
