Definitions

  • the invention relates to a knitting machine of the type defined in the preamble of claim 1.
  • the knitting tools that are to transfer the stitches are prepared for the transfer process by first selecting them using a pattern device, as in a normal knitting or catching process, and then driving them out to the transfer position above the knitting height by means of the switched-on drive part or the lock switch .
  • This has the advantage that conventional pattern devices that can be programmed for knitting and, if necessary, also for catching can be used for the selection of the knitting tools and that an additional pattern command is only required to control the drive part or the lock switch.
  • the invention is therefore based on the object of providing a knitting machine of the type mentioned at the outset with a stitch transmission device and of designing it in such a way that the transmission process can be controlled in a manner similar to conventional knitting machines.
  • the invention creates for the first time a knitting machine of the type mentioned at the beginning, which has a transmission device.
  • This transmission device is advantageously designed such that the pattern device only has to decide between “knitting” and “non-knitting”.
  • the knitting tools selected for knitting and coupled to the associated cam disks are then influenced by means of the transmission device in such a way that they are driven either into the usual knitting position or into a transmission position.
  • this also has the advantage that when using an electronic or electromagnetic pattern device, it can easily be ensured that in the event of a power failure all needles are driven to the knitting position and not to the transfer position.
  • the knitting tools are pulled off solely by pulling parts which can be moved along the needle beds.
  • This measure makes it possible to provide very small system distances, regardless of the division of the knitting machine, without knitting advantages in particular in the case of coarse divisions, e.g. to enable a change in the mesh length by means of movable lock parts (DE-A 2 531 705), to have to do without.
  • a flat knitting machine with two V-shaped needle beds 1 is shown, in the grooves of which knitting tools in the form of knitting needles 2 with hooks 3, preferably latch needles, are mounted in a longitudinally displaceable manner.
  • a drive shaft 4 is rotatably mounted, on which a number of eccentric cams 5 corresponding to the number of knitting needles 2 is lined up in a rotationally fixed manner.
  • the two arms 7 and 8 encompass the cam plate 5 from two sides in such a way that their points of contact with the cam plate 5 lie on a line which is essentially parallel to the needle axes, so that the drive elements 6 rotate from the cam plates 5 when the drive shafts 4 rotate are raised and lowered parallel to the needle axes and in this way carry out expulsion and trigger strokes.
  • the drive element 6 On a lateral part facing the connecting web 9, the drive element 6 has a shaft 11 which is mounted in a sliding and rotating bearing, so that the drive element 6 is held on the cam plate 5 on the one hand due to the action of the pressure spring 10 and on the other hand due to the sliding - And pivot bearing is slidably and rotatably mounted.
  • a foot 12 is provided on an upper section of the drive element 6, the upper edge of which serves as the drive-out edge 13 and the lower edge serves as the pull-off edge 14 for an associated ram 15 arranged below the associated knitting needle 2.
  • the foot 12 protrudes into a recess formed on the front of the plunger 15, which extends between a foot 16 of the plunger 15 that grips under the foot 12 and a further, central foot 17 of the plunger.
  • the bottom of the recess is stepped and contains three stages 18, 19 and 20 which act as expulsion elements.
  • the upper edge of the foot 16 acts as a trigger element.
  • the foot 16 of the plunger 15 has such a length that it overlaps the foot 12 in any possible position of the drive element 6 during a trigger stroke of the cam plate 5.
  • the steps 18, 19 and 20, on the other hand, are dimensioned such that the foot 12 in the basic position of the plunger 15 shown in FIG. 2 in either two coupling positions of the drive element 6 or the connecting web 9 either engages under one of the steps 18 or 19 or in one additional decoupling position is outside the effective range of all three stages 18, 19 and 20.
  • a pattern device for the pattern-based control of the knitting needles 2, contains for each knitting needle 2 a pattern-controllable holding magnet 21 and a control spring 22, the free end of which is pretensioned against the pole face of the holding magnet 21 by means of a projection provided on the shaft 11 can. If the holding magnet 21 attracts the control spring 22, the connecting web 9 is placed by the pressure spring 10 against the associated cam plate 5 until the output edge 13 engages under the step 19 and, during the next output stroke of the cam plate 5, the associated push rod 15 into one required for the normal knitting process Knitting position.
  • control spring 22 is dropped by the holding magnet 21 according to the pattern, then its free end optionally lies against one of two stops formed on the shaft 11, so that either the drive element 6 locks in a retracted position despite the action of the pressure spring 10 and therefore the plunger 15 is not driven out or the foot 12 is only advanced so far that it engages under the step 18 and therefore drives out the pusher 15 into a catch position.
  • each pusher is articulated in its middle part by means of a joint 23 to a knitting needle 2 arranged above it in such a way that it follows the expulsion and withdrawal movement of the pusher 15 caused by the cam plate 5, regardless of which pivot position of the pusher 15 occupies.
  • the pusher is normally held by a U-shaped compression spring 24, which is arranged between an upper part of the pusher lying above the joint 23 and the knitting needle, in the pivot position shown in FIG. 2, in which the back of it lies under the joint 23 , the section 18 to 20 containing section rests on the needle bed 1.
  • Each knitting needle 2 also has a knitting foot 25.
  • the knitting feet 25 can cooperate with a plurality of lock plates 26 which, according to FIG. 1, are fastened to endless belts 27 which are each mounted on at least two deflecting rollers 28 and by means of a drive device (not shown) with a knitting speed speed in the direction of the arrow.
  • the lock plates 26 are mounted with their lower edges on supporting bodies 29, which are guided and supported in the groove in each case by a slide rail 30 as they pass the needle beds 1, which are fastened to a cover 31 that extends parallel and stationary over the entire width of the associated needle bed 1 is.
  • the upper edges of the lock plates 26, on the other hand, slide between the upper end of this cover 3 and a counter-guide 32. As a result, the lock plates 26 are always arranged at the same invariable height as they pass the needle beds 1.
  • Each lock plate 26 can carry an adjustable trigger part, not shown in FIGS. 1 and 2, which serves to control the last phase of the withdrawal of the knitting needles 2 by briefly acting on the knitting feet 25 in such a way that the stitches formed by them are adjusted by adjustment of the deductible section received preselected length.
  • the knitting machine described so far differs from known knitting machines of this type (for example DE-A 2531 705, DE-A 2531 734, DE-A 2531 762 and DE-A 2701 652) only in that the drive elements 6 are not directly, but indirectly via the pushers 15 act on the knitting needles 2 and the pushers 15 have a third step 20, the function of which will be explained below.
  • a description of further details and the mode of operation of the knitting machine according to FIGS. 1 and 2 can therefore be dispensed with.
  • the knitting machine according to the invention additionally has a transmission device for transferring or transferring stitches formed on knitting needles of one needle bed to associated knitting needles of the other needle bed.
  • a transmission device for transferring or transferring stitches formed on knitting needles of one needle bed to associated knitting needles of the other needle bed.
  • Such transfer devices are generally known in flat knitting machines with reciprocating or rotating slides both with lateral offset of the two needle beds relative to one another (DE-A 2228547) and without this offset (DE-B 2443231 and WO 81/00868).
  • a stitch transfer with offset would have the disadvantage that the large number of knitting systems arranged along the needle beds would have to be stopped until the entire transfer process has ended, which is associated with a considerable loss of production, particularly in the production of special patterns would.
  • the transfer process is therefore preferably carried out without an offset.
  • the transferring knitting needles 2 according to FIGS. 3 to 6 are provided with the known lateral spreading springs 34, which serve to spread the stitches guided by the transferring knitting needles 2 during the transfer process in such a way that the hooks 3 of the receiving knitting needles 2 spread Penetrate stitches unhindered and take over in a known manner. If all knitting needles of both needle beds are provided with such spreading springs 34, the stitches can optionally be transferred from all selected knitting needles of one needle bed to the assigned knitting needles of the other needle bed and vice versa.
  • the transmission device contains, as essential components, the lock plates 26 with elements mounted thereon that control the transmission process and a control mechanism by means of which these elements are prepared for the transmission process.
  • 3 shows a knitting needle 2 and the associated pusher 15 in the position shown in FIG. 2.
  • the drive element 6 has been selected by means of the pattern device for a knitting process, so that the output edge 13 of a foot 12 in the lowest position engages under the step 19 and the pusher 15 and the knitting needle 2 connected to it by the joint 23 in accordance with an arrow 36 in the can drive out the knitting or closing position required for normal stitch formation.
  • a pivot bearing 37 is fastened on the side of the lock plate 26 facing away from the knocks 15, in which a lever 38 is pivotably mounted .
  • One arm of the lever 38 is biased by a compression spring 39 supported on the lock plate 26.
  • the other lever arm has a section 40 which is angled by 90 ° and which carries on its outer end which projects through the lock plate 26 a slide 41 which, when the lock plate 26 is transported past the needle bed, the upper sections of the pushers which are pushed out of the needle bed by the compression springs 24 15 faces and extends parallel to the needle bed.
  • control disk 42 for example square in the side view, which is pivoted at one of its corners by means of a pin 43 parallel to the lock plate 26 on the arm of the lever 38 carrying the slide 41.
  • the control disk 42 is supported on the lock plate 26 with an edge remote from the pin 43, as a result of which the lever arm in question is held against the pressure of the compression spring 39 at such a great distance from the lock plate 26 that the slider 41 cannot influence the pusher 15.
  • control disk 42 is pivoted by 90 ° about the pin 43 by means of a control arm 44 attached to it in such a way that a channel close to the pin 43 now moves te of the control disk 42 is supported on the lock plate 26 and, as a result, the lever arm in question assumes a substantially smaller distance from the lock plate 26 under the influence of the compression spring 39. As a result, the slider 41 is pressed against the upper sections of the pushers 15 passing by (FIG.
  • the pusher After reaching the transfer position, the pusher should be held in the transfer position for a while so that the receiving knitting needle has enough time to properly pierce and take over the stitch held by the transferring knitting needle. It follows that the foot 12 should be decoupled from the stage 20 when the transfer position is reached, because a sufficiently long downtime can only be provided if the drive stroke of the cam plate 5 and the foot 12 has not yet ended when the transfer position is reached . To enable the decoupling, it is ensured according to the invention on the one hand that the plunger 15 slides off the slider 41 when the transmission position is reached. On the other hand, an additional decoupling element working with a positive fit is provided to support the compression spring 24, which cannot always carry out the pivoting back of the ram alone with the required security.
  • the length of the stop edge 47 parallel to the needle bed 1 and to the slider 41 is dimensioned such that it begins shortly behind the rear end of the slider 41 in the running direction of the lock plate 26 and ends a few needle divisions behind this end.
  • the drive element 6 and with it its foot 12 are pulled off again in the direction of an arrow 48 from the associated cam plate 5 (FIG. 6), the foot 12 resting on the lower foot 16 of the plunger 15 and consequently also pulls this and the associated knitting needle 2 until the last part of the pulling movement is carried out by a pulling part 49 acting on the knitting foot 25, adjustably fastened to the lock plate 26 and known per se (DE-A 2 531 705).
  • Fig. 7 shows a top view of the lock parts carried by four lock plates, not shown, which are moved in the direction of an arrow P from left to right past the needle beds.
  • the lock parts shown in FIG. 7 below a line 50 are assigned to the front needle bed
  • the lock parts arranged above line 50 are assigned to the rear needle bed and each form a lock represented by reference numerals 51 to 54.
  • the leading locks 51 and 53 for transferring stitches from the knitting needles of the front needle bed to the knitting needles of the rear needle bed and the trailing locks 52 and 54 are set for producing normal knitting or tuck stitches.
  • Each lock contains a stroke limiting part 55, a guide part 56 assigned to it, a lock part 57 effective in the withdrawal direction, a further guide part 58 assigned to it, a switchable transmission part 59 and a trigger part 60, all of which are each connected to a lock plate 26 (FIGS. 3 to 6) are attached.
  • the sliding pieces 41 and tapping edges 47 which are fastened in accordance with FIGS. 3 to 6 are indicated.
  • webs 61, 62 and 63 of the upper edges of the knitting feet 25 are also indicated, respectively these would describe a full rotation of a cam disc 5 if the foot 12 of the drive element 6 would constantly engage either the step 20 or the step 19 or the step 18 of the plunger 15.
  • a complete transmission cycle is described below using the locks 51 and 53.
  • the slide 41 of the front needle bed is brought into the position shown in FIG.
  • the drive elements of all those knitting needles of the front needle bed which are to transfer a stitch are selected by means of the pattern device for «knitting», i.e. the associated control springs 22 are constantly attracted by the electromagnets 21, while all other drive elements are selected for “non-stricting”.
  • the transmission part 59 of the front needle bed remains switched off, so that it cannot influence the knitting feet 25.
  • the drive elements 6 of all those knitting needles that are supposed to take over a stitch are selected for “catch”, i.e.
  • the associated control springs 22 are dropped by the electromagnets 21 so late that the feet 12 of the drive elements are advanced to below the steps 19 of the associated pushers 15.
  • the transmission part 59 of the rear needle bed is switched on so that it can act on the knitting feet 25.
  • the slider 41 of the rear needle bed remains switched off.
  • the slide 41 of the lock 51 acts on the pushers 15 one after the other in accordance with FIG.
  • the feet 12 of all the drive elements 6 selected for knitting are arranged under the steps 20 of the associated pushers 15, so that the knitting feet 25 of the knitting needles connected to them are driven out along the path 61.
  • the knitting feet 25 are guided between the stroke limiting part 55 and the guide part 56 on a path which is expedient for the transmission process.
  • the transferring knitting needles of the rear needle bed are driven out along the path 63 into the catch position because the associated drive elements have been prepared accordingly by means of the pattern device, so that the hooks of these knitting needles pass through the now spread stitches of the knitting needles of the front needle bed which are in the transfer position.
  • the transferring knitting needles are drawn off up to the knitting height by the lock part 57 in a manner suitable for transferring.
  • the takeover knitting needles driven out at the catch height are drawn off from the transfer part 59 to close to the through position.
  • the relevant slider 41 remains switched off, as is indicated by dashed lines in the locks 52 and 54 (cf. FIG. 3).
  • all of the pushers 15 remain in the pivot position shown in FIG. 3, so that the feet 12 of the drive elements 6, depending on the pattern, reach under either the step 19 or the step 18 or no step at all.
  • the associated knitting needles are driven out in the knitting or closing position (lock 52) or in the catch position (lock 54) or left in the continuous position at somewhat later times compared to the transfer process.
  • the transmission parts 59 are each switched off.
  • the pull-off part 60 enables the knitting needles to be drawn off evenly even with small system widths, regardless of whether they have been driven out into the catching or knitting position or whether the knitting position is somewhat higher or lower depending on the division provided in the individual case. This has the advantage that the same lock plates, cams and drive elements can be used for all occurring divisions.
  • the trigger part 60 also allows the mesh length to be varied. As shown in FIG. 7 for the lock 52 and FIG. 8, all that is required for this is the trigger part 60 with means known per se (DE-A 2531 705, DE-A 3003811 and DE-A 3138337) in the direction of an arrow V slidably on the associated lock plate. In addition, it is expedient to assign a guide part 64 to the lower edge of the pull-off part 60 in order to ensure an exact stitch length even at high speeds.
  • FIG. 8 also schematically shows the interaction between the take-off part 60, the drive elements 6 and the knitting needles 2 when a normal knitting process is carried out.
  • a dashed line indicates a path 65 on which the ideally flat feet 12 of the drive elements 6 move during the expulsion and extraction strokes.
  • Another dashed line indicates a path 66 on which the upper edges of the feet 16 of the pushers 15 would move if they would follow the feet 12 in a form-fitting manner. In fact, between the step 19 and the upper edge of the foot 16, however, there is a relatively large clearance corresponding to the distance between the tracks 65 and 66.
  • the upper edges of the feet 16 only follow the path 66 exactly when they are being driven out, because at this point the feet 12 reach under the step 19 and take them with them without play.
  • foot 12 begins to descend again after crossing the maximum of path 65, foot 16 cannot immediately follow because foot 12 must first bridge the play between step 19 and foot 16.
  • the feet 16 initially remain in a contour line 67. This theoretically applies until the extension of the contour line 67 intersects the descending part of the path 65 at 68. At this moment, the foot 12 touches the upper edge of the foot 16.
  • the pull-off part 60 acting on the knitting feet 25 is therefore set such that it leads the web somewhat and the feet 16 of the pushers are already pulled off at a point 69 lying in front of the point 68 along a path 70. Since this web 70 is always between the two webs 65 and 66 until it meets the web 66 again at a point 71 at the beginning of the subsequent expulsion cycle, the foot 12 always moves somewhere in the range between 19 and during the trigger strokes Top edge of the foot 16 lying area without colliding with it.
  • the switching of the sliders 41 and the transmission parts 59 takes place with the aid of a control mechanism.
  • 1 contains two electrically controllable lifting magnets 72 and 73 which are arranged in front of the beginning of the front needle bed 1 and whose downward projecting lifting rods each carry a control cam 74 and 75, respectively.

If the solenoid 72 is not energized, the control cam 74 is arranged outside the effective range of the control arm 44.
  • a control arm 44 pivoted with the aid of the control cam 74 remains in this position until the lock plate 26 reaches the rear end of the needle bed and comes into the range of action of a fixed return curve 76 of the control mechanism, onto which the control arm 44 runs.
  • the control arm 44 is pivoted by 90 ° in the opposite direction to the control curve 74, so that it again assumes the out-of-work position shown in FIG. 3, so that a new selection process can be initiated when the solenoid 72 passes again.
  • Control arms 44 already in the out-of-work position are not influenced by the reset curve 76.
  • the control cam 75 can act in a corresponding manner on a control arm 78 which pivots the transmission part 59 into the advanced working position.
