Definitions

  • Knitting machine needles are known in many different designs. Knitting machine needles are inserted into a knitting machine and often moved over one or more butts of the knitting machine needle in a channel of a needle bed of the knitting machine. For this purpose, the butt of the knitting machine needle interacts with a lock on the knitting machine. In the case of high-speed knitting machines in particular, the knitting machine needle is subjected to strong accelerations. Knitting machine needles that have a latch are often used ("latch needles"). The tongue performs numerous rapid pivoting movements that serve to form stitches together with a hook. The high dynamics of this pivoting movement can lead to errors in stitch formation on high-speed knitting machines. Such failures are favored by the inevitable wear and tear on the hook and tongue. The hook and the latch are arranged at a front end of the knitting machine needle and connected to the butt of the knitting machine needle via a shank.
  • the JP62191888U and the EP1424416A1 proposed to apply predetermined breaking points to the foot of knitting machine needles so that the foot breaks off before major damage occurs.
  • a similar predetermined breaking point is also shown in CN2534208Y .
  • the in the CN2534208Y The illustrated needle has a groove in the underside of the needle shaft below the position of the latch return. Such a groove serves to relieve the strain on the stitch when the stitch slides over the tongue which is in the reverse position. This strain relief occurs when the existing fabric (preferably the previous stitch) engages in this groove.
  • Such throats for strain relief are in many designs of knitting machine needles below or in the immediate vicinity of the to find the tongue-retraction position. These grooves are not predetermined breaking points, since the grooves are not intended to be broken with any appreciable probability by the force that the yarn exerts on the hook.
  • the DE1635837A1 shows a needle equipped with sections on the shank designed to prevent the transmission of shock waves from the foot to the hook. These sections can be designed as sections with modified mechanical properties or as sections with a reduction in the cross section of the needle. In each exemplary embodiment, the special sections are implemented at points on the shaft where the shaft has its greatest height. It is therefore not a question of predetermined breaking points, since the shaft is not very likely to break at these points.
  • the DE4320956A1 and the DE19503048C2 show predetermined breaking points on sewing or embroidery needles.
  • the DE3311361 A1 shows a knitting system with such long, slender knitting machine needles.
  • the object is achieved by a knitting machine needle according to claim 1 and a knitting system according to claim 13.
  • the knitting machine needle according to the invention comprises a hook for the formation of stitches, which delimits the shank in the longitudinal direction of the shank, or starts there, and which ends in a hook point.
  • the hook is followed by a first drive section.
  • the force for moving the knitting machine needle is transmitted from a cam part of the knitting machine to the drive section of the knitting machine needle.
  • the drive section can be designed as a foot that protrudes beyond the shaft in the positive vertical direction of the shaft.
  • the drive section can be formed by a coupling point.
  • a coupling element usually has a foot and the force for moving the knitting machine needle acts in a known manner on the coupling point of the knitting machine needle.
  • the knitting machine needle according to the invention can also include a latch.
  • the tongue can be pivoted on the shank in such a way that in its closed position it closes the interior of the hook and that the tip of the tongue in its retracted position in the longitudinal direction of the shank is on the first Drive section has.
  • the tongue can be rotatably mounted on the shank on pins formed on the shank, a hinge or an axle.
  • the knitting machine needle according to the invention is characterized by a predetermined breaking section for separating the hook from the first driving section, which is formed by a section of the shank extending in the longitudinal direction thereof.
  • a "section”, as used herein, means greater than infinitesimal length in the longitudinal direction of the needle.
  • the frangible portion is located entirely within a first shank portion extending in the longitudinal direction of the shank between the tip of the hook and the first drive portion.
  • a predetermined breaking portion has a non-infinite extent in the longitudinal direction of the knitting machine needle.
  • the knitting machine needle is likely to break at the breaking point due to forces transmitted through the yarn when the movement of the needle in the needle bed is impeded or the stitch fails to be knocked over.
  • the shank of the knitting machine needle extends over the entire length of the same.
  • the shaft can only be divided into different functional sections.
  • An end portion of the shank forms a hook and has adjacent to this hook a portion which can come into contact with a yarn in the knitting process.
  • the shank includes a section (the drive section or butt) via which the movement of the knitting machine needle is initiated.
  • Sections lying between the above sections are used, for example, to guide the knitting machine needle (in a needle bed) and connect the above functional sections.
  • a frangible portion will advantageously be located in a portion of the shank that serves the functions of guiding and connecting other functional portions.
  • the shank can have sections with different heights.
  • the sections of the shaft of different heights can merge into one another at transition points.
  • a first transition point may be located near the drive section.
  • a second transition point may be located near the hook.
  • the second transition point can be double or longitudinal in the longitudinal direction spaced three times as far from the tip of the hook as the tip of the tongue in the supine position of the tongue.
  • the distance of the second transition point from the tip of the hook can also have any value between the above values.
  • the knitting machine needle can have a predetermined breaking section, which is set up in such a way that the hook can be separated from the first drive section by a force that acts on the hook and is less than 80% of the force at which a needle of the same construction without a predetermined breaking section is permanently deformed.
  • the predetermined breaking section can in particular be set up in such a way that the hook can be separated from the first drive section when a corresponding force acts on the hook in a negative vertical direction. It is clear to the person skilled in the art that at least the diameter (“fineness") of the yarn is related to the breaking strength of the needle and that the breaking strength is certainly also determined by the fineness of the needle. The fineness also determines the maximum diameter of the yarn to be used.
  • the tensile strength of the yarn is certainly also largely dependent on the yarn diameter, so that the overall fineness is a needle property that has a major influence on the design of the predetermined breaking section.
  • the gauge (or "press") of the knitting machine needle may be determined by the gauge of the tape from which the knitting machine needle is stamped and may be measured in the width direction of the knitting machine needle. With a needle with a pressure of 0.4mm, the force at which the hook is separated from the first drive section can be approximately from 5N to IN depending on the design of the predetermined breaking section, while a knitting machine needle of the same construction would be permanently deformed at approximately 8N. "Deform” is used here in particular as a generic term for "bending".
  • a special test for verifying the suitability of a predetermined breaking section consists of placing the needle with its underside (the side facing away from the foot in its height direction) on a table, pushing the needle on the table, hook first, over the edge of the table until the hook-side (front) part of the needle protrudes at least up to the predetermined breaking section over the edge of the table. If the hook is then subjected to a defined breaking or buckling force, the break should take place at the predetermined breaking section. If the force is further increased (examples see above) and plastic deformation occurs and there is no breakage, the suitability of the needle for the purposes of this document must be doubted.
  • the knitting machine needle may have a predetermined breaking portion located entirely within a second shank portion, the second shank portion being in Extends longitudinally of the shaft between the position of the tip of the tongue in the retracted position of the tongue and the first drive section.
  • the knitting machine needle may have a predetermined breaking portion which is located entirely in a third shank portion which begins in the longitudinal direction of the knitting machine needle at the point which is spaced two tongue lengths from the point of articulation of the tongue in the direction of the first butt and in the longitudinal direction of the knitting machine needle terminating at the point three tongue lengths from the pivot point of the tongue toward the first drive portion, the tongue length being the distance between the pivot point of the tongue and the tip of the tongue.
  • This articulation or bearing point of the tongue can have a bearing seat in the tongue in the form of a circular opening into which an axle or a pin engages. The tongue length can be measured from the center of this opening.
  • the tip of the tongue is the point of the tongue that is farthest from this center point, and the distance between these two aforementioned points can represent the length of the tongue.
  • the predetermined breaking section can be located in a fourth or fifth shaft section.
  • a fourth shank portion may extend from the pivot point of the tongue to a second transition point.
  • a fifth shank portion may extend from the position of the tongue tip in the rear position to a second transition point.
  • the predetermined breaking section can be located in a sixth shank section described below:
  • compound needles have guide means for a slider (a hook closing element) at a distance in the longitudinal direction from the point of the hook, which are located in the longitudinal direction on the drive section extend. These guide means do not extend below the tip of the hook. This results in a minimum distance between the tip of the hook and the guide means in the longitudinal direction.
  • the sixth shank portion may extend from 1.5 times the minimum distance to three times the minimum distance from the hook tip.
  • the knitting machine needle can have a distance of at least 75 mm from the hook-side end of the needle in the longitudinal direction of the shank to the hook-side beginning of the first drive section or the first butt in the longitudinal direction.
  • the knitting machine needle can have a shank which has a height ("chest height") of 0.8 to 1.5 mm in the area in which the latch is articulated on the shank, at the highest point in this area. This height is measured in the height direction.
  • the knitting machine needle can have a shank which, in the section in which the predetermined breaking section is arranged, can have a height which is between 50% and 70% of the breast height.
  • the knitting machine needle can have a shank which is stamped out of a band material and which, in the areas in which its thickness still corresponds to the thickness of the band material, has a thickness, measured in the width direction, of 0.3 to 0.6 mm or up to 0.7 mm to have.
  • the knitting machine needle can include a predetermined breaking section, which has a reduction in the shank cross section perpendicular to the longitudinal direction.
  • the plane spanned by the height direction x and the width direction y of the needle runs “perpendicular to the longitudinal direction”.
  • the knitting machine needle can have a predetermined breaking section, which has a reduction in the shank cross section, which is achieved by reducing the shank in the vertical direction.
  • a predetermined breaking section designed in this way can have the advantage that it can also be attached during a stamping process and thus no separate manufacturing process is required.
  • the predetermined breaking section can thus be produced inexpensively.
  • the height of the shaft can be reduced in the height direction from above and/or from below. However, it would also be conceivable to provide a recess (or several) in the shank that does not reach through the upper side and the underside of the shank or the predetermined breaking section.
  • the knitting machine needle can have a predetermined breaking section which, at the point with a maximum reduced cross section, has a reduction of at least 10% and at most 60% in the height or the height dimensions of the adjoining shank or the adjoining shank sections. This leaves 40% to 90% of the cross-sectional area (in a plane transverse to the longitudinal direction of the needle) at the thinnest point of the predetermined breaking section.
  • the reduction in cross-section or height in question can also be distributed over different sub-sections of the predetermined breaking section (20% from above, 25% from below).
  • a notched configuration of the cross-sectionally reduced points of the predetermined breaking section makes it possible to obtain a position that is relatively precisely defined in the longitudinal direction for separating the hook from the drive section.
  • a concentration of stresses takes place at the position of the frangible portion.
  • the width of the needle can of course also be reduced. The procedure can be equivalent to the measures described above for reducing the height of the shaft dimensions.
  • the knitting machine needle may have a shank reduction in the height direction, which has a triangular shape with an included angle of 60° to 120°. An opening angle of 90° can be particularly advantageous.
  • the three corners formed in the shaft can be rounded. With small reductions in the height direction, a radius of rounding of at least 0.02 mm is advantageous, with larger reductions in the height direction, the roundings can also advantageously be designed with radii of 0.35 mm or, for example, 0.4 mm or 0.5 mm.
  • the reduction in height can also be trapezoidal, in the form of a step or have a different geometry.
  • grooves which for example relieve the stitches when sliding over the tongue in their backward position
  • Such grooves have a larger opening angle and a flat profile to allow the stitch to enter and exit easily .
  • most predetermined breaking sections should bring about a defined break at a defined point, so that the opening angles of the side flanks are smaller in such a predetermined breaking section.
  • the stitch relief groove is in a place over which the stitch slides. Due to its shape, the predetermined breaking section could "catch" the stitch and thus endanger the knitting process.
  • the predetermined breaking point for example, behind the position of the tip of the latch when the latch is in the back position.
  • Another consideration that speaks in favor of positioning the predetermined breaking section in the rear area of the needle is the leverage effect: when a stitch, and here in particular a stitch that has not been knocked off transfers large force to the interior of the hook, the distance from the hook increases the leverage of that force on the breakaway portion.
  • the knitting machine needle can have a predetermined breaking section, the material of which has a lower elongation at break than sections of the remaining shaft.
  • the behavior of the knitting machine needle in the event of an overload can be specifically controlled by this embodiment of the predetermined breaking section (in addition to or as an alternative to a reduction in height or similar measures). Different deformations in the plastic range of the material are suppressed in favor of a targeted break when the load for which the knitting machine needle is designed is significantly exceeded.
  • the knitting machine needle is advantageously made of steel. In the case of steel, the elongation at break can be influenced by specifically adjusting the hardness or the structure. In this way, the structure in the predetermined breaking section can be designed to be brittle and/or coarse-grained.
  • needle beds is used in the present publication as a generic term for those parts of knitting systems that guide needles during knitting. In particular, these are knitting cylinders and dials on circular knitting machines and flat needle beds on flat knitting machines.
  • the DE3311361A1 and the DE102014118217A1 describe measures to be able to further increase the performance of high-speed knitting machines and show examples of typical knitting systems with corresponding knitting machine needles in the figures.
  • the present invention deals in particular with the improvement of knitting machine needles and knitting systems which are suitable for the high-performance requirements indicated in these documents.
  • the two publications describe knitting systems with knitting needles that have a very long, thin shank section between the hook and the first foot. Large parts of this long and thin shank section are guided laterally (in the direction of the width of the needle) in the relevant needle beds according to the two aforementioned documents, not by webs of the needle bed, but by sinkers. Knitting systems of the aforementioned type achieve high knitting performance with a high degree of fineness.
  • the knitting system according to the invention contains a needle bed with guide means and at least one channel base, which are set up to receive knitting machine needles and to guide and support them in their longitudinal direction during their intermittent movement.
  • needle beds in the form of cylinders, dials or flat needle beds, for example for flat knitting machines, can be considered.
  • the knitting machine needles are accommodated in channels by the needle bed and are guided by the channel webs in the width direction of the knitting machine needles and are supported by the channel base in the negative height direction of the knitting machine needles.
  • the guidance of the knitting machine needles in the width direction does not necessarily take place along the entire length of the knitting machine needle, but can also only take place in a rear section of the knitting machine needles.
  • the knitting machine needle can also be guided in the width direction, for example, by other knitting tools (this is the case, for example, with knitting systems according to the publications DE3311361A1 and the DE102014118217A1 the case). The same applies to the support of the knitting machine needles on the bottom of the channel.
  • the knitting system according to the invention also contains at least one cam part for transmitting force to at least a first drive section of a knitting machine needle accommodated in the needle bed.
  • a butt of the knitting machine needle often protrudes from the channel of the needle bed and is accommodated in a web-shaped indentation ("cam") in the cam.
  • a circular knitting machine has a plurality of cams, each of which defines a portion of the path that a needle butt (of a clutch part) travels in one total rotation of the needle cylinder of a circular knitting machine. This relative movement of the knitting machine needle to the cams in the width direction of the needle, the cams transmit the force to the relevant drive section or needle butt that moves the needle in the longitudinal direction of the needle during knitting in a circular knitting machine.
  • the knitting system according to the invention is characterized in that at least one of the knitting machine needles has a predetermined breaking section for separating the hook from the first drive section.
  • the predetermined breaking section is formed by a first section of the shank, which extends in its longitudinal direction.
  • the frangible portion is located entirely within the first shank portion, which extends in the longitudinal direction of the shank between the tip of the hook and the first drive portion.
  • the knitting system according to the invention can be designed in such a way that the guide means and the at least one channel base of the needle bed, the at least one cam part and the position of the drive section and the predetermined breaking section on the at least one knitting machine needle are coordinated in such a way that the at least one knitting machine needle during knitting operation is at least temporarily is driven so far out of the guide means that the guide means no longer at least partially support the predetermined breaking section of the at least one knitting machine needle.
  • the predetermined breaking section is located above the first cam segment, at least when the knitting machine needle is in the driven-out state. This special tuning allows the behavior of the system to be precisely controlled when unusually high forces act on the hook or on the section of the knitting machine needle that is no longer supported.
  • the high forces can then act via a relatively long lever from the hook to the predetermined breaking section. Since the predetermined breaking section lies approximately at a point at which the needle bed begins to support the driven-out knitting machine needle, there is a high probability of a very defined break occurring at or in the predetermined breaking section. It is therefore important here that the predetermined breaking section is not arranged too far forward in the direction of the hook, because otherwise an undefined breakage would occur on the hook due to the leverage effect Point can arise at which the knitting machine needle is again supported by the needle bed. If the predetermined breaking section is completely in the supported area, an undefined break can occur at the edge of the needle bed. High forces can occur, for example, due to the fabric being pulled off if stitches are not knocked off and accumulate in the hook. A pull-off force can then quickly act on the hook, which exceeds the usually occurring pull-off force, for example by a factor of 2 or more.

This applies all the more since in the load position shown by a force F, a predetermined breakage due to the front part of the needle 1 with the hook 2 “buckling away” is very likely.
