Definitions

  • the invention relates to a flat knitting machine with spring shaft needles arranged in the needle channels of the needle beds, each having a front needle foot that always protrudes from the needle bed and a rear needle foot that disappears in the needle bed due to the spring shaft being self-supporting, with sliding boards arranged behind the spring shaft needles one working foot each and a front end that can be slid under the spring shaft of the spring shaft needle to selectively lift the second needle foot, with jacquard boards with at least two feet each that are arranged behind the sliding boards, slidably sliding on these, and with a lock system for selecting and actuating the needles and boards, which has at least two needle counterbores arranged symmetrically to the central longitudinal axis of the lock system and displaceable in the lock plane in the region of the second needle feet.
  • Such a flat knitting machine is known for example from DE-35 23 989 C1.
  • the sliding boards are designed there as latching boards, while the needles are selected by engaging selection flaps on a selection foot of the jacquard boards and thereby driving out the jacquard boards.
  • the known flat knitting machine achieves that the needle channel milling in the needle bed can be carried out without a shoulder, i.e. in a milling cycle with a constant milling depth, without the full variety of binding technologies including transferring stitches and knitting with different pull-off depths within a knitting row.
  • the invention has for its object to provide a flat knitting machine of the type described in the introduction, in which the structure of the lock and knitting system is further simplified and its operating properties are additionally improved.
  • the further switchable lock parts in the area of the second needle feet as well as the further switchable lock parts in the area of the lifting board feet are expediently arranged symmetrically to the central longitudinal axis of the lock system.
  • the switchable lock part in the area of the first needle feet and the switchable lock parts in the area of the second needle feet and the lifting board feet are advantageously switchable in action, while forming long stitches and short stitches Catch handles the switchable lock part in the area of the first needle feet and the switchable lock parts in the area of the second needle feet out of action and the switchable lock parts in the area of the lifting board feet are switchable in action.
  • the switchable lock part in the area of the first needle feet and the switchable lock parts in the area of the second needle feet as well as the switchable lock parts in the area of the lifting board feet are expediently switchable together into and out of the lock level.
  • a lock part which is symmetrical to the central longitudinal axis of the lock system is advantageously provided for holding the lifting plate on its lifting plate foot against a withdrawal movement on its upper edge of the lock part and against an expulsion movement on its lower edge of the lock part.
  • two fixed lock parts arranged symmetrically to the central longitudinal axis of the lock system are advantageously provided for pushing apart the sinker feet and front jacquard board feet, while at a second selection point a fixed lock part symmetrical to the central longitudinal axis of the lock system is provided for driving out the lifting board feet and holding the jacquard board feet against an ejection movement is.
  • two first selection points and two second selection points are provided in each case arranged symmetrically to the central longitudinal axis of the lock system, in order to be able to carry out the full variety of knitting processes in each slide running direction.
  • the selection feet of successive jacquard boards and the associated selection flaps are expediently staggered in a known manner in the longitudinal direction of the needle channel.
  • the lock system for selective needle withdrawal as shown in Fig. 1 consists of non-hatched, fixed lock parts, five hatched lock parts 16, 17, 18, 19, 20, which are controllable and can be brought into and out of operation as desired, and four movable in the double arrow direction Needle countersink 21, 22, 23 and 24.
  • the lock parts 16, 17, 18, 19 and 20 are always shown hatched when they are switched off from the lock level out of action.
  • the lock system is symmetrical to its central longitudinal axis M.
  • Fig. 2 shows a lock system for constant needle withdrawal, which, apart from the two needle counters 23, 24 displaceable in the double arrow direction, only consists of non-hatched, fixed lock parts.
  • This lock system is again symmetrical to its central longitudinal axis M.
  • the needle and sinker run for the three-way technique through the lock system for selective needle withdrawal will be described below with reference to FIG. 3.
  • the hatched lock parts 16, 17, 18, 19, 20 are inactive here.
  • a spring shaft needle 32, a lifting plate 33 and a jacquard plate 34 are shown in different working positions, one behind the other, in a needle groove 31 in a needle bed 31.
  • the spring shaft needle 32 has a central needle foot 35 which protrudes continuously from the needle bed 31 and a needle foot 36 at its needle end 37 which can be raised resiliently from the needle bed 32 with the aid of the lifting plate 33.
  • the lifting plate 33 has one Lifting board foot 38.
  • the jacquard board 34 has a front jacquard board foot 39, a middle selection foot 40 and a rear sliding foot 41.
  • Fig. 4 spring shaft needle 32, lifting plate 33 and jacquard plate 34 are in position 1 - basic position -.
  • a selection flap 42 on the selection foot 40 is pivoted so that a lock part 43 engages with the sliding foot 41 of the jacquard plate 34 protruding from the needle bed 31 to drive it out.
  • spring shaft needle 32, lifting plate 33 and jacquard plate 34 are in position 2 for jacquard selection / stitching / transferring.
  • the front end of the lifting plate 33 abuts the needle end 37.
  • spring shaft needle 32, lifting plate 33 and jacquard plate 34 are in position 3 - needle foot 36 raised, start transfer -.
  • a lock part 44 lies between the lifting board foot 38 and the front jacquard board foot 39 and presses the lifting board 33 and the jacquard board 34 apart.
  • a lock part 45 engages on the needle foot 35 which protrudes continuously from the needle bed and prevents the spring shaft needle 32 from being driven out via a comb match.
  • the liftable needle foot 36 protrudes from the needle bed 31.
  • FIG. 8 shows spring shaft needle 32, lifting plate 33 and jacquard plate 34 in position 10 - forming stitches.
  • the spring-liftable needle foot 36 is sunk in the needle bed 31 out of work.
  • spring shaft needle 32, lifting plate 33 and jacquard plate 34 are shown in position 12 - forming stitches.
  • the lifting plate 33 engages under the spring shaft needle 32 again, so that its lifting needle foot 36 protrudes out of the needle bed 31 into the working position.
  • position 1 the needle and sinkers are in the basic position.
  • the spring shaft needle 32, the lifting plate 33 and the jacquard plate 34 are arranged one behind the other in the needle bed 31 on a constant deep needle channel base. If the needle foot 36 is to be brought into the working position, the jacquard plate 34 must be selected and preselected with the lifting plate 33.
  • the selection flap 42 is pivoted away, the jacquard plate 34 remains in its raised or not pushed away position in such a way that the lock part 43 grasps the sliding foot 41 and the jacquard plate 34 and the lifting plate 33 move to the right up to the needle end 37, cf. 3 and 5, position 2.
  • lock part 44 takes over the task of moving the lifting plate 33 further up and the jacquard plate 34 again, cf. 3 and 6, position 3.
  • the lock part 45 holds the spring shaft 32 in position on the needle foot 35, so that the lifting plate 33 can slide under the needle foot 36 and bring it into the lock area.
  • This first selection point - position 2 - is used to select the stitch formation or for the needle drive to pass the stitch.
  • the needle counterbore 23 has been switched to the lower dashed position during the last slide reversal.
  • the needle countersink 23 thus detects the needle foot 36 and pushes the spring shaft needle 32 up until it is detected on the needle foot 35 by a transfer lock part 46.
  • the needle counterbore 23 remains in the same position as the comb, so that the needle foot 36 is first gripped by a lock part 47 and is driven out by it until the needle foot 35 is gripped by an upper needle lifter 48, cf. Fig. 3 and position 8.
  • the spring shaft needle 32 is now withdrawn from the needle counterbore 24 to a preselected withdrawal depth and by a lock part 51 in the starting position or basic position - position 15 in FIG. brought to comb equilibrium position, in which the needle foot 36 is sunk in the needle channel.
  • the second selection point for catching or taking over - position 6 in FIG. 3 - brings the needle foot 36 into the working position so that it is gripped by the lock part 49 and the spring shaft needle 32 is driven out by the lock part 49 until the needle foot 35 is in the region of a Lock part 52 comes and is driven out at catch height with the help.
  • the lifting board foot 38 is removed from the lock part 50, cf. Fig. 3, position 11 held.
  • the needle foot 36 slides off the lifting plate 33 and disappears in the needle channel.
  • both selection points remain unaffected, ie the selection flap 42 does not swivel out, then the jacquard plate 34 is pressed with the rear end into the needle channel and the sliding foot 41 is not removed from the lock part 43 detected.
  • the needle foot 36 is sunk in the needle channel and can therefore not be caught by any lock part.
  • the spring shaft needle 32 remains out of action.
  • the needle selection for taking over stitches is done in the same way as used for the catch selection.
  • the needle pass for knitting long and short stitches is shown in Fig. 10.
  • the controllable lock parts 16 to 20 are put into operation.
  • the first selection point - position 2 those needles that are to knit long stitches are selected, and at the second selection point - position 6 - those needles that are to knit short stitches.
  • the upper needle countersinks 22 form the short and the lower needle countersinks 24 the long stitches.
  • the passage of the needles and sinkers which are selected at the first selection point - position 2 - is the same as that described for three-way technique stitches in connection with FIG. 3.
  • the passage of the needles and sinkers, which are to form short stitches, begins at the second selection point - position 6.
  • position 6 the needle foot 36 raised in action is detected by the lock part 17 and driven out until the needle foot 35 is taken over by the lock part 16.
  • the lock part 48 then brings the spring shaft needle 32 to full stitch.
  • the lifting plate 33 remains stopped by the lock part 50.
  • the needle foot 36 slides off the lifting plate 33 and disappears in the needle channel. Since the lock part 20 has been put into operation, the lifting plate 33 is in the following Starting position subtracted.
  • the needle foot 36 can no longer be grasped by the lifting plate 33, thus remains inactive and this needle is pulled less far from the upper needle countersink 22 by the needle foot 35, which is constantly in operation.
  • the needle foot 36 which is out of action, cannot be grasped by the needle counterbore 24 and thus slides under it.
  • FIG. 11 shows the needle passage for long stitches and short tuck handles.
  • the lock parts 16, 17 and 18 are inactive and the lock parts 19 and 20 are in operation.
  • the needle selection for long stitches takes place.
  • the further needle course is the same as already described for the three-way technique, FIG. 3.
  • the needles that are to form small tuck handles are selected in the tapping selection, FIG. 3, position 6.
  • the course of the needle and sinker is the same as that shown in FIG. 3.
  • the lock part 20 is switched on, the lifting plate 33 is pulled off there, so that a decoupling takes place in position 14 and the needle forming the tuck handles on its foot 36 cannot be grasped by the needle counterbore 24.
  • Fig. 12 shows the lock system for constant needle withdrawal (Fig. 2) with a needle and sinker pass for three-way technique.
  • Fig. 13 shows the lock system for constant needle withdrawal (Fig. 2) with a needle and sinker pass for loops.
