Definitions

  • the invention relates to a warp knitting machine with knitting needles that have a predetermined pitch, and at least one jacquard laying bar, the laying needles by actuators of a needle control between two end positions can be moved back and forth by fixed end stops are specified in the direction of the bars.
  • any Laying needle from a needle lane into the neighboring needle lane that is, by a knitting needle division.
  • the two end positions are determined by that the laying needle either on a left or a right end stop is brought to the system.
  • Relocation can be operated by harness cords Pushing elements (DE 40 28 390 A1), by piezoelectric Bending converter (DE 42 26 899 C1) or any other Way.
  • This controllable single needle offset leads in combination with an offset of the whole Jacquard bar for a variety of pattern options.
  • the invention has for its object a warp knitting machine of the type described in the introduction, which enables an even greater variety of patterns.
  • each laying needle can have three different ones Positions, namely two end positions and a middle position, and therefore with one of three neighboring needle streets. This enables, especially if the jacquard laying bar via mirror disks, sample gears or the like. offset laterally, a variety of novel Pattern options. For single needle offset the known measures can be retained. Because the forces that move the laying needle from one to the other Shift end position, hold this needle too against the additional one brought into its path of movement Stop that defines the middle position.
  • the actuators of the stop control transverse to the plane of movement of the laying needles are relocatable. This allows a mechanical one very easy control of the additional stops.
  • a block that goes from the actuator into a front and a rear position is shiftable, in the front part a front track between the one stop and a first additional stop, in the rear part a rear track between the other end stop and a second additional stop and one of the additional stops limited transition between the tracks.
  • the actuators of the needle control are first piezoelectric bending transducers with one end are held bar-tight and at the free end carry a laying needle. Such bending transducers are proportionate little space, so that the Place the actuators of the stop control well to let.
  • the first bending transducer in a left and a right deflection position are switchable.
  • the bending transducers are therefore included even force on the end stops and with something force pressed against the additional stops.
  • the actuators of the stop control second piezoelectric bending transducers are which are held with one end and with the act free end on the additional stops. These actuators can also be arranged to save space.
  • the second bending transducers can be free End the abovementioned abutment or the abovementioned Wear block.
  • Barrier-proof cross stops preferably limit the Stroke of the second bending transducer. These cross stops prevent that the forces exerted by the bending transducers be transferred to the laying needles. So be excessive material stress and wear avoided.
  • the second bending transducers are preferably between the Carrier of the bar and the first bending transducers arranged.
  • the second bending transducers can with their flat side close to the carrier and hardly take up any additional space.
  • the width of the strip-shaped bending transducer is three Needle sizes are available because each lay needle can take three different positions.
  • first and second bending transducers are provided a predetermined number of first and second bending transducers, respectively carry.
  • the segments allow the first and second bending transducer outside the warp knitting machine to assemble and after installation via cable bundle to connect with the rest of the stop control.
  • the segments 16 can be 16 or 16 second Wear bending transducers. Such units can be operate particularly well with digital control mechanisms.
  • An optimal patterning option is obtained when there are at least three jacquard laying bars. Then all needle lanes can be controlled with jacquard Laying needles are occupied.
  • the neighboring middle positions a distance equal to four times the needle pitch to have. This allows even with only half Jacquard needle number to work. In this case four jacquard bars for the full machine fineness needed.
  • a first bending transducer unit 3 has an angular segment 4, which is connected to the carrier 2 via a connecting piece 5 is.
  • the segment carries 16 first piezoelectric ones Bending transducer 6, each at its free end Have laying needle 7.
  • a second bending transducer unit 8 also has an angular segment 9 which is attached to the carrier 2 by a screw 10.
  • the Segment carries 16 second piezoelectric bending transducers 11, which have an abutment 12 at the free end. Cable bundles 13 and 14 serve the bending transducer units 3 and 8 after installing segments 4 and 9 on Carrier 2 with the associated control devices connect.
  • each laying needle 7 shows three jacquard laying bars 101, each have a structure according to FIGS. 3 to 5. With these three laying bars, the laying needles 7 are like this staggered against each other that - if everyone Laying needles 7 are in the middle position - everyone A laying needle is assigned to Nadelgasse.
  • These three Laying bars are fixed to the machine frame by a bridge 30 connected, the relative swinging motion through the knitting needles. It is also possible, each laying rail in the longitudinal direction to be offset by an offset control unit. Likewise it is possible to use the ingot package with fixed knitting needles to swing.
  • FIG. 9 there is a bending transducer unit 3 with associated segment 4, which carries a total of 16 first bending transducers 6. These are via a bundle of conductors 31 with a 17-pin connector 32 connected. Behind it is indicated that 16 second Bending transducers 111 are provided which block 120 Taxes. These bending transducers are via bundle 33 connected with a 17-pin connector 34. Hint knitting needles 35 are illustrated, by the Alleys 36 swing the laying needles 7 through. If all Laying needles 7 are in the middle position every fourth alley 36 is covered with a laying needle 7. With four of the same design, but each with a needle pitch staggered laying needles 7 can be achieve that all needle lanes 36 at the same time can be occupied.
  • the laying needles 7 also displaced in other ways are considered by piezoelectric bending transducers, for example with push pins or sinkers and return springs.
  • the control of the additional stops can be done purely mechanically.
