Definitions

  • Knitting machines with hold-down plates arranged between the needles are already known. With the help of the hold-down boards is knitting without the help of a knitting device possible below the comb gap.
  • the hold-down boards have a functional part in the stitch formation area acting edges and protrusions. Of the Functional part can be between an open and a closed position be pivoted.
  • Embodiments of hold-down boards are for example in DE 36 09 539 C2 and DE 39 35 763 C2 described. These well-known hold-down boards are in board beds arranged above the needle beds guided, on the surface of which parts of the lock slide, the hold-down boards in their open or closed position move.
  • Hold-down boards have therefore already been proposed which are divided into two elements: one one Functional part performing a pivoting movement and a linear movable shaft part.
  • the two parts are articulated with each other connected. This allows the linear movement of the driven Shaft part in the required pivoting movement of the functional part between the open and closed positions the board are translated. Examples of such boards are known for example from FR 1 207 319 and EP 0 567 282.
  • the advantage of the two-part hold-down boards is that that the control of the shaft parts at some distance from Comb gap can take place.
  • these are hold-down boards in construction, of course, more complex than one-piece Circuit boards.
  • the present invention has for its object a Knitting machine with hold-down boards to create one piece are and still not near the comb gap area must be controlled.
  • the task is done with a knitting machine, especially one Flat knitting machine, with arranged between the needles Solved boards that have a front functional part in the Meshing area engaging edges that extend around a lengthwise of the needle bed extending axis between a front and a rear position is pivotable, and one essentially shaft part aligned parallel to the needles have to drive the boards, the functional part and the shaft part through an elastically resilient web are connected to a one-piece component. Due to the elastic resilient web is a transmission of translatory movement of the shaft part in a rotational movement of the functional part possible. This means that the drive of the board on Part of the shaft and thus away from the comb gap. The resilient design of the web also causes a restoring force, the board automatically in a starting position moved back.
  • the boards can be in a relaxed state Bridge the functional parts of the boards in the front or in the rear position or in an intermediate position between the front and rear positions. Depending on the rest position, the board must either only in one of the two directions - closing direction or opening direction - Or actively driven in both directions will.
  • the boards can be one-piece stamped parts, however also composed of several parts, for example by welding will.
  • the functional parts of the boards can be guided laterally in a manner known per se to the required exact position of their intervention in the stitch formation area to secure.
  • the boards can be from one to the board shafts attacking circuit board lock.
  • the Shaft parts of the sinkers one vertically out of the needle bed have protruding foot on which the lock parts of the circuit board lock can attack.
  • the board lock can do this arranged at a relatively large distance from the comb gap be so that the comb gap area freely accessible from above remains.
  • the boards according to the invention can also be used by friction and / or positive engagement with the neighboring needles connect and thereby move with the needles.
  • the boards according to the invention can also at carriage-free knitting machines with single motor needle drive be used.
  • For coupling the needle drive with the board drive are a variety of constructive Possible solutions conceivable.
  • the shaft parts of the For example, side plates with flat spring elements be that engage in recesses on the needle shafts.
  • the needle shafts each with two consecutive recesses be provided, in which the flat spring element of the shaft part the adjacent board one after the other during needle advance is insertable by the functional part of the board after reaching a front end position on a stop supports, whereby the flat spring element from the front recess slides out and to the rear recess.
  • the coupling between needle shaft and platinum shaft takes place here alternately via a positive and a frictional connection. If the Board bridge is designed such that in its idle state the functional part of the board is open, must open the Functional part no active control of the board. Rather, the board opens automatically as soon as that Flat spring element snaps into the rear recess.
  • the board 11 has a functional part 12 which is in the stitch formation area the knitting machine engages and thus a knitting without knitted fabric deduction below the cross.
  • the Design of the functional part 12 can depend on the desired Functions may be different.
  • the circuit board 11 also has a shaft part 13 which in the needle bed 10 is mounted for longitudinal displacement. On the shaft part 13 there is a board foot 14 arranged on the lock parts 15 of a circuit board lock attack.
  • the shaft part 13 and the functional part 12 are interconnected by an elastically resilient web 16 connected.
  • the functional part 12 is about an axis 17 pivoted.
  • the base 14 of the lock parts 15 acted on, this results in a translational Movement of the shaft part 13 which over the web 16 in a rotational movement of the functional part 12 is converted becomes.
  • the opening movement of the circuit board 11 is thereby a contact section 18 limits during the closing movement is limited by the contact section 22.
  • the functional part 12 is also laterally through a guide surface 19 guided.
  • the geometric shape and cross section of the web 16, the location of a node K and the Distance A of the fulcrum 17 from the plane T of the translational Movement of the platinum shaft 13 designed so that by implementing the translational movement of the shaft 13 in a rotational movement of the functional part 12 in the web 16 one such great tension arises that the resulting Restoring force the functional part 12 and the platinum shaft 13 exactly moved back to their starting position.
  • the restoring forces the hold-down boards can be in the same Castle level can be included.
  • Fig. 3.1 shows a circuit board 11 'which in the relaxed state Is in the closed position. To open the board, a force must be applied be initiated in the direction of arrow 20. 3.2, however shows a circuit board 11 '' which in the idle state in the open Position is. A must here to close the board 11 '' Force exerted in the direction of arrow 21 on the board base 14 ′′ will.
  • 4.1 to 4.3 show a hold-down board 30, the can be driven by a needle 40.
  • the board 30 is in the voltage-free state opened.
  • Your platinum shaft 31 has no board foot that protrudes vertically from the needle bed, but a laterally attached flat spring 32 (Fig. 4.3), which by their design both a shape and can also form a frictional connection to the needle shaft 33.
  • a laterally attached flat spring 32 (Fig. 4.3)
  • Fig. 4.3 In the needle shaft two recesses 34 and 35 are provided in the the flat spring 32 can snap into place.
  • the board 30 is with your Flat spring 32 snapped into the groove 34. In this position is the functional part of the board 30 to about three quarters closed. This position is shown in Fig. 4.
  • Needle 40 now begins its propulsion movement, taking it there the board 30 with, so that the functional part is circular closes. This will make the one in the needle hook Mesh held back during needle advance. If the closing movement of the functional part 36 is supported the circuit board 30 with its contact surface 37 on a back 38 a lateral guide groove for the functional part 36. If now the needle 40 is advanced, presses the rear one Edge of the recess 34, the flat spring 32 together. Subsequently causes the flat spring 32 to frictionally engage the needle shaft 33, so that the functional part 36 of the board 30 continues remains closed. Just before the needle 40 reaches the position "Catch height" has reached, the flat spring 32 slides into the second recess 35.
  • the board 30 is now from the needle 40 decoupled so that by the stored in the web of the board 30 Restoring force the functional part 36 of the board 30 opens again. This is an unimpeded thread insert a handle is possible.
  • the needle 40 the functional part 36 remains open. If not a tuck handle but a stitch is formed the needle is not moved back yet, but still advanced further.
  • the functional part 36 closes again and also remains closed during the forward movement of the needle.
  • the Needle 40 then begins its retraction movement by one Friction between the needle shaft 33 and the flat spring 32nd an opening movement of the functional part 36 is initiated.
  • the needle shaft 33 engages, of course, other elements and constructions for generating a friction and / or Form fit between the needle 40 and the board 30 is conceivable.
