Definitions

  • the invention relates to a knitting machine with a needle carrier, which is equipped with parallel guided, longitudinally displaceable and controlled by a needle lock curve, between which controlled by a sinker lock curve, overlapping the needle carrier edge and each having a sinker shaft, which project transversely to the needles and are movably mounted in the longitudinal direction and are controlled in such a way that they are moved at the respective knitting point after inclusion against the pulling-off movement of the assigned needles and transversely to them outwards and after the stitch has been knocked off against the needle-driving movement and transversely to them.
  • a circular knitting machine of this type is known from DE-OS 2 025 144.
  • the transverse movement of the sinkers with respect to the associated needles after the inclusion serves to transfer the sinkers with them in this circular knitting machine.
  • the corresponding sinkers are brought back into the starting position against the pushing-out movement of the needle, whereby they are first moved transversely to the needles in order to achieve that they come with their throat and nose enclose the half-finished row of stitches and prevent the knitted fabric from being carried along when the needles are driven out.
  • the sinkers each provided with a sinker shaft are supported with their sinker shaft on a sinker lock curve, which is arranged outside a sinker ring screwed to the needle cylinder.
  • the circuit board ring is provided with a horizontal flange in which radial slots are formed, in which the individual circuit boards are guided in a radially movable manner.
  • the radial movement transverse to the needles is controlled by a special design of the sinker lock curve, which simultaneously controls the sinker ejection, and which is assigned a drive-in control curve for the sinkers arranged on a pot-like, stationary machine head that overlaps the flange of the sinker ring.
  • this circular knitting machine is relatively complicated and requires, among other things, that the needles inserted into the guide grooves of the needle cylinder are not only surrounded by the sinker ring, but also by the sinker lock curve and the sinker shafts.
  • the circuit board control curve controlling two movements is relatively complicated, while, on the other hand, a certain minimum value of the needle pitch cannot be undershot, because otherwise it is no longer possible to store the circuit boards properly in the slots in the flange of the circuit board ring.
  • the object of the invention is to provide a knitting machine with longitudinally and transversely to the needle movement movable boards, which is characterized by a simple, reliable construction in that it allows to achieve a very fine needle pitch and can work at high speed at the same time.
  • the knitting machine mentioned at the outset is characterized according to the invention in that the sinkers are guided with their shafts to form guide webs for the respectively adjacent needle shafts on the needle carrier and an expulsion cam which gives the sinkers the transverse movement to the needles is arranged directly on the needle carrier .
  • the sinker shafts directly form the guide webs for the needle shafts results in a very fine needle pitch, the smallest value of which is only due to the thickness of the sinkers.
  • the needles and the sinkers are easily accessible after the usual removal of the lock, while in the case of circular knitting machines, a sinker ring is completely eliminated, so that the structure is very simple and user-friendly.
  • the arrangement of the drive-out cam of the sinkers directly on the needle carrier further simplifies the structural conditions and makes it possible to dispense with complicated curved surfaces for an drive-out lock, so that it is easy to manufacture.
  • the sinkers each engage, with a foot arranged on the sinker shaft, in a sinker lock channel forming the sinker lock curve, which is arranged following the needle carrier and thus controls the insertion and expulsion movement of the sinkers counter to the needle movement.
  • the drive-out cam can have a curved surface which is arranged on the needle carrier base and runs along the needle carrier and can be scanned by a nose on the shaft of each plate.
  • the curved surface can be an inclined surface which is formed directly on the needle carrier and can be widened outwards towards the needle carrier edge and which can be produced very easily with high accuracy on the needle carrier during manufacture.
  • the needle shafts In principle, it is possible to store the needle shafts directly on the surface of the needle carrier between the sinker shafts. In order to improve the guidance of the needle shafts and to reduce wear, it is advantageous, however, if the needle shafts are mounted radially on guide webs inserted into the needle carrier, between which the sinker shafts are laterally guided.
  • the guide bars therefore have two functions: on the one hand they guide the board shafts laterally and on the other they form the raceways for the needle shafts.
  • the sinker shafts project in the radial direction by a predetermined amount beyond the needle shafts, so that the needle shafts are securely guided over their entire radial extent.
  • the sinkers and / or their shafts in the region of the expulsion cam are pressed radially inward toward the needle carrier base by spring force.
  • the arrangement can be made, if necessary, in such a way that the needle shafts in the area between the needle carrier base and the output cam are also radial by spring force are pressed inwards towards the needle carrier base.
  • the movement of the sinker can be controlled in such a way that a needle lock curve for the needles results from continuously curved, sinusoidal arc pieces that merge seamlessly into one another, thereby reducing the needle load to a minimum and at the same time keeping blows and vibrations away from the needles.
  • the sinker lock curve can consist of adjoining, continuously curved arcs, so that no abrupt movements triggering vibrations and high mass acceleration forces occur even when the sinker is being controlled.
  • the knitting machine can be operated with only one row of needles in the needle carrier, i.e. be designed as a single-speed machine, but the idea according to the invention can naturally also be applied to a two-speed knitting machine.
  • Such a machine is then designed with a second row of needles arranged in a second needle carrier, between the needles of which there are also printed circuit boards which are designed and controlled in accordance with the boards of the first needle carrier.
  • the knitting machine according to the invention can be both a flat and a circular knitting machine, the needle carrier in one case being a needle bed and in the other case being a needle cylinder or a dial.
  • the execution as a single-bed flat knitting machine results in The practical advantage that without a knitted fabric deduction and without weights, which occurs each time a knitted fabric is after a goods drop, otherwise required, can be worked. It is also conceivable, in a double bed flat knitting machine, for example, to equip a needle bed, for example the front bed, in accordance with the invention and to have it worked, so that it is also possible to knit single-surface goods without deduction on this machine.
  • the needle cylinder 1 of a circular knitting machine is equipped on its circumference with latch needles 2, which are mounted so as to be longitudinally displaceable parallel to one another.
  • the latch needles 2 have on their needle shafts 3 feet 4 which engage in a needle lock channel 5 forming a needle lock curve of a lock casing 6 surrounding the needle cylinder 1, which is of multipart design in a manner known per se, which is not shown in detail.
  • a relative rotary movement is generated between the lock jacket 6 and the needle cylinder 1, so that the needle lock channel 5 gives the latch needles 2 the expulsion and pull-in movement required for the knitting process.
  • a circuit board 7 is arranged between two latch needles 2, which overlaps the needle cylinder edge 8 and has a circuit board nose 9 as well as a throat 10 and a wedge edge 11.
  • Each circuit board 7 is provided with a circuit board shaft 12, with which it is guided on the needle cylinder 1 lying directly between the shafts 3 of adjacent latch needles 2.
  • guide webs 3 are inserted radially into the needle cylinder 1 and consist of a wear-resistant material which results in a good friction pairing with the needle shafts 3 and the blank shafts 12.
  • the guide webs 13 are arranged at a distance from the needle pitch and directly form the radial support of the running surface for the needle shafts 3.
  • Each sinker shaft 12 is provided with a foot 14 which projects into a sinker lock channel 15 formed on the lock casing 6 and is controlled by it in such a way that the sinkers 7 are given a movement in the opposite direction to the needle movement, as will be explained in more detail below.
  • a sinker drive lock is provided, which is in the form of an inclined surface 16 which is rotated directly on the needle cylinder 1 and extends outwards towards the needle cylinder edge 8 and on which the sinkers 7 each have a shaft 12 molded nose 17 are supported.
  • the drive lock 16, in the manner shown in FIGS. 5, 6, causes one of the Board lock channel 15 caused expulsion movement of the board shafts 12, the boards with respect to the latch needles 2 are moved radially outwards.
  • the sinker shafts 12 are in the area of the drive-out cam 16 under the action of a spring force directed radially inwards towards the needle cylinder base, which is generated by two continuous tension springs 18 running all around. which are supported laterally against projections 19 formed on the board shafts 12.
  • the sinker shafts 12 protrude in the radial direction by a predetermined amount beyond the needle shafts 3 in the manner shown in FIG. 2, so that the needle shafts 3 can carry out their movement unaffected by the springs 18.
  • the needle shafts 3 In order to prevent the needle shafts 3 from being carried along in the area of the needle heads during the radial outward movement of the plates 7, they are pressed radially onto the guide webs 13 in the area between the drive-out cam 16 and the needle cylinder edge 8 by the spring force exerted by a circumferential spring 20 .
  • the sinker shafts 12 are formed with an open groove 21, which ensures that the radial mobility of the sinkers 7 is not impeded by the spring 20.
  • the latch needle 2, controlled by the needle lock channel 5 goes down, while the circuit board 7, controlled by the board lock channel 15, performs an opposite movement, i.e. is driven out.
  • the nose 17 runs onto the inclined surface of the drive-out cam 16, with which the plate 7 radially outwards in the direction of an arrow 23, i.e. is moved across the needles 2. This transverse movement causes the knitted fabric 11 to be released from the nose 9 and the throat 10 of the board 7 (exclusion position). This radial movement of the individual adjacent plates 7 is illustrated in FIG. 4 for a knitting point.
  • the needle lock curve consists of continuously curved, sinusoidal arc pieces which merge seamlessly into one another, which ensures that no abrupt impacts or vibrations are transmitted to the latch needles 2.
  • FIG. 8 shows that the blank lock curve also consists of adjoining, continuously curved arches 24, which are connected to one another at 25 by arcs with a smaller radius of curvature.
  • the boards 7 therefore also experience a relatively smooth, jerk-free movement.
  • the sinkers and the needle lock curve result in a very high working speed of the knitting machine with low needle and sinker stress.
  • the exemplary embodiment described is a single-font machine which is only equipped with latch needles 2 and sinkers 7 in the needle cylinder 1. Basically, it is also possible to build a two-speed machine according to the same principle. In this machine there is then only an additional dial which carries the second row of needles, whereby between the individual needles of this row of needles, in turn, the same-shaped boards 7 are arranged, which are controlled in their expulsion movement by a board lock channel provided in the dial lock and one of which is on the
  • the output cam associated with the dial is assigned corresponding to the output cam 16, by means of which they are moved with their lugs 17 in the manner described transversely to the sinker needles.
  • the invention can also be implemented in the form of a flat knitting machine in a single-bed or two-bed design.
  • the needle bed is used as the needle carrier instead of the needle cylinder.
