Definitions

  • the invention relates to a circuit board of a flat knitting machine for holding down loops.
  • Such boards of flat knitting machines are for example from the EP 0 238 797 and EP 0 424 717 known.
  • the blanks of the flat knitting machine after the EP 0 238 797 B1 are at the same time hold-down elements and stitches, while the blanks of the flat knitting machine from the EP 0 424 717 B1 merely exert a hold-down function and interact with a stitch pattern arranged rigidly on the needle bed.
  • the boards of both known flat knitting machines have the same disadvantages in common. Both blanks have only one hold-down surface, so it is not possible to securely hold down stitches of both single-bed and double-bed knitted fabrics.
  • the EP 0 567 282 shows pivotable stitches with stitch retention hooks for flat knitting machines with a single needle drive.
  • the pivoting movement of the mesh images is initiated by translationally moving slider. These slides are frictionally connected to the needles so that they can only perform movements in the same direction to the needle.
  • a variation of the stitch retention function depending on the type of knitted fabric, ie of double-bedded or single-bed knitted fabrics is also not given here.
  • the DE 1 137 825 discloses a board with two hold-down surfaces, both of which can be used only for single-bed knitted fabrics.
  • a hold-down board having a hold-down surface for a bedding knitted fabric and a hold-down surface for a two-bed knitted fabric is known.
  • the area for entertainige knitted fabric is, however, arranged below the surface for one-bed knitted fabrics and unable to retain meshes of very different sizes and also fulfill a security function in single-bed knitted fabrics.
  • the present invention is based on the object to further develop the circuit board of a flat knitting machine so that the holding down of stitches of single-bed and double-bed knitted fabrics is optimally possible.
  • the stitches are held down by the hold-down boards of the opposite needle bed. This usually requires a different height position with respect to the comb gap than holding down the stitches of a single-bed knitted fabric in which the hold-down boards hold down the stitches of the own needle bed. Due to the multiple hold-down surfaces, the boards are outstandingly suitable for both single-bed and double-bed knitted fabrics.
  • the additional hold-down surfaces can also fulfill a security function, as long as a mesh should break away from the deepest low-adhesion area. This mesh is then picked up by one of the following surfaces. This risk of sliding down from the hold-down surface is given in particular for large meshes, since they rest against the hold-down surfaces only with low tension.
  • the plurality of mesh retaining surfaces are arranged at different, equally or differently spaced peripheral locations of the boards.
  • the plurality of mesh hold down surfaces may have a substantially radial orientation with respect to the axes of rotation of the sinkers. However, they can also be designed hook-shaped.
  • the axis of rotation of the board may preferably be arranged above the needle shafts. Also by this measure, the hold-down effect of the board can be improved, since the mesh holddown surfaces with relatively high above the needle bed arranged rotary axes better enclose the mesh legs in the lower pivot position.
  • the boards may have a plurality of mesh hold-down surfaces and at least one stitch pattern surface. They thus combine both the hold-down and the stitch-forming function.
  • the boards may only have a plurality of mesh hold-down surfaces and cooperate with arranged rigidly on the needle beds mesh images.
  • FIG. 1 shows a device 100 of a flat knitting machine for holding down and forming stitches.
  • a needle bed 4 is shown in the needles 7 are guided longitudinally displaceable in grooves 41 .
  • the groove bottom is marked 42 .
  • the needle bed 4 grooves 43 for receiving board guide pieces 3 on which boards 1 are pivotally guided.
  • the board guide pieces 3 have for this purpose a circular recess 31 into which a circular segment 14 of the board 1 engages. In this way, the circuit board 1 about the rotational axis 18 in the direction of arrow D and in the opposite direction D ' pivotally limited.
  • the stop surface 33 of the sinker guide piece 3 limits the opening movement of the board 1 in the direction of arrow D and the surface 34, the movement down in the direction of arrow D '.
  • the stitching wire 45 for the stitches is passed through slots 19 in all boards 1.
  • the circuit board 1 has a functional surface 11 for forming stitches, an active surface 12 for holding down loops of single-bed knitted fabrics and further active surfaces 13 , 13.1 , 13.2 for holding down loops of the opposing needle bed in double-bed knit fabrics in flat knitting machines with two needle beds.
  • the pivoting movement of the board 1 in the direction of arrow D or D ' is triggered by a spring element 2 .
  • This spring element 2 is guided in a cylinder disposed above the needle bed 4 slider bed. 6
  • the slide bed 6 has longitudinal grooves 61 into which the spring elements 2 are inserted.
  • the spring element 2 has a U-shaped spiral spring section with legs 22, 24 .
  • the free leg 24 is bent in the section 25 to the outside.
  • the spring element 2 engages the circuit board 1.
  • the section 25 sets at the surface 16 of the board 1 at.
  • the surface 17 of the board 1 is acted upon by the spring element section 25. This is done by moving the spring element 2 in the groove 61 , as below also in the Fig. 2 and 3 is illustrated.
  • the displacement is triggered by lock parts of the carriage of the flat knitting machine, which engage a foot 21 of the spring element 2.
  • the slide bed 6 is connected via a connecting bar 5 with the needle bed 4.
  • the connecting strip 5 has two dovetail-shaped sections 51, 52 , which engage in correspondingly shaped grooves on the needle bed 4 and the slide bed 6, respectively.
  • the sliding movement of the spring element 2 is limited by a wire 63 which is guided in a slot 23 of the spring element 2. Via the section 25, a displacement movement of the spring element 2 is translated into a rotational movement of the board 1.
  • the portion 25 of the spring element 2 engages at a distance from the axis of rotation 18 of the board, which is less than the distance of the hold-down surface 12 to the axis of rotation 18th
  • Fig. 2 shows in contrast to Fig. 1 in which the circuit board 1 is shown in its off-mode, the board 1 in its fully closed position in which it retains a mesh leg 9 of the needle 7 with the surface 12.
  • the board 1 has been so far swiveled in the direction of rotation D 'until its surface 16 rests against a stop surface 34 of the blanking guide piece 3.
  • the spring element has been moved to trigger this rotational movement of the board 1 in the direction of arrow X maximum forward.
  • the section 25 of the spring element 2 now engages the surface 17.
  • the board 1 can move in the direction of arrow D against the spring force of the spring element 2 limited move upwards.
  • the position of the board 1 is shown for large meshes 9, which does not pull the board 1 against the spring force upwards. Should the stitch 9 detach from the surface 12, it could be recaptured by one of the surfaces 13 to 13.2.
  • FIG. 3 however, the arrangement according to FIG Fig. 2 when holding down small stitches 9.
  • the board 1 has now been pivoted against the direction of the arrow D 'and against the force of the spring 2 upwards.
  • the pivoting movement is limited by the spring element 2 itself.
  • the free leg 24 of the U-shaped spiral spring portion is now on the leg 22 at.
  • Another Nachobenex the board 1 through the mesh 9 is therefore excluded.
  • the additional surfaces 13 to 13.2 fulfill a backup function.
  • the spring element 2 is guided in the grooves 61 of the slide bed 6 with friction. This means that it retains its position in each slide position, when the lock parts are no longer act on it. As a result, all spring elements 2 and thus also the boards 1 can be kept in a defined pivot position.
  • Fig. 4 shows in cross section a device 200 for holding down meshes of a flat knitting machine with two needle beds 4, 4 '.
  • Each of the needle beds is in the example shown with blanks 1, 1 ', spring elements 2, 2' and knitting needles 7, 7 ', as in Fig. 1 are shown equipped.
  • the device 101 for holding down loops of the second needle bed 4 ' is identical to the device 100 of the needle bed 4.
  • the effect of Hold-down surface 12, 12 ' limited.
  • the board 1 of the front needle bed 4 additional functional surfaces 13, 13.1, 13.2 and the board 1 'of the rear needle bed 4' additional functional surfaces 13 ', 13.1', 13.2 ' on.
  • These functional surfaces grasp the mesh legs 9 'of the stitches which are on the shaft of the needles 7, 7' opposite them and hold them back when the needles 7, 7 ' carry out their propelling movement.
  • Fig. 4 has the functional surface 13 of the board 1 of the front needle bed 4, the mesh leg 9 'of the needle 7' of the rear needle bed 4 'detected.
