Abstract

A knitting machine, especially a flat-bed knitting machine, has a self-sprung intermediate sinker (26) mounted longitudinally displaceably in a needle channel (10) of a needle bed by means of a control sinker (40) and having a press foot (38). This intermediate sinker acts on an elastically flexible coupling part (16) connected in an articulated manner to a needle (12) at one end and supported on the bottom (14) of the needle channel at the other end and can guide the working foot (24) of the coupling part into the region of the lock parts (23) of the knitting lock plate (22) or move it out of this region. The longitudinally displaceable intermediate sinker (26) is tensioned resiliently between the bottom (14) of the needle channel (10) and the underside (31) of a control-sinker bed (30). The intermediate sinker (26) and the bottom (14) of the needle channel and/or the control-sinker bed (30) have means for positioning the intermediate sinker in its longitudinal direction. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Strickmaschine, insbe­sondere auf eine Flachstrickmaschine, mit einer in einem Nadelkanal eines Nadelbetts mittels einer Steuerplatine längsverschiebbar gelagerten, selbstfedernden Zwischenpla­tine mit einem Drückerfuss, welche Zwischenplatine auf einen einends mit einer Nadel gelenkig verbundenen, andern­ends auf dem Boden des Nadelkanals abstützenden, elastisch biegsamen Kupplungsteil einwirkt und dessen Arbeitsfuss in den Bereich der Schlossteile führt bzw. aus diesem Bereich hinausbewegt.The invention relates to a knitting machine, in particular to a flat knitting machine, with a self-resilient intermediate plate with a presser foot, which is mounted in a needle channel of a needle bed by means of a control plate and can be displaced longitudinally , elastically flexible coupling part acts and its working foot leads into the area of the lock parts or moves out of this area.

Die Nadeln und die zugeordneten Nadelstösser bzw. Platinen einer Strickmaschine gleiten in den Nadelkanälen eines Na­delbettes. Mit den Schlossplatten eines Schlittens hin- und herbewegte Schlossteile betätigen die Nadeln durch aus den Betten hinausragende Nadelfüsse oder durch Arbeitsfüsse von mit den Nadeln gelenkig verbundenen Kupplungsteilen. Zur Ausführung der Grundoperationen müssen einerseits die Na­delbetriebsstellungen Stricken/Nichtstricken und Ueberga­be/Uebernahme von Maschen, das Umhängen, mittels umschalt­barer Schlösser eingestellt und andererseits die einzelnen Nadeln selektiv der Betätigung durch den betreffenden Schlossteil entzogen werden können.The needles and the associated needle pushers or sinkers of a knitting machine slide in the needle channels of a needle bed. Lock parts moved to and fro with the lock plates of a slide actuate the needles by means of needle feet protruding from the beds or by work feet of coupling parts articulated with the needles. To carry out the basic operations, on the one hand, the needle operating positions knitting / non-knitting and transferring / transferring stitches, transferring, must be set by means of switchable locks and, on the other hand, the individual needles must be selectively withdrawn from actuation by the lock part concerned.

In der CH-PS 517 853 wird eine Strickmaschine, insbesondere eine Flachstrickmaschine, beschrieben. In den Nadelkanälen der Nadelbetten gelagerte Platinen mit einem von den Nadel­schlössern beeinflussbaren Arbeitsfuss dienen dem Steuern der Nadelbewegungen. Die Platine ist als an ihren beiden Enden abgestützter elastisch biegsamer Stab ausgebildet, auf welchen ein Druckglied einwirken kann. Der Arbeitsfuss der Platine ist im Bereich ihrer maximalen Durchbiegbarkeit angeordnet. Der Arbeitsfuss ist bei gebogener Platine aus dem Bereich der Schlossteile hinausbewegt.CH-PS 517 853 describes a knitting machine, in particular a flat knitting machine. Boards in the needle channels of the needle beds with a working foot that can be influenced by the needle locks serve to control the needle movements. The circuit board is designed as an elastically flexible rod supported at both ends, on which a pressure member can act. The working foot of the board is arranged in the area of its maximum bendability. The working foot is moved out of the area of the lock parts when the circuit board is bent.

Nach einer Variante der CH-PS 517 853 wirkt das Druckglied nicht direkt auf die elastisch biegsame Platine ein, son­dern auf eine federnde Zwischenplatine. Diese hat einen haarnadelförmig gebogenen Endabschnitt und ist zwischen einer Leiste und dem Grund des Nadelkanals verschiebbar ge­lagert. Zum Betätigen der Zwischenplatine sind zwei Druck­platinen notwendig, wobei die Zwischenplatine die Feder­funktion, die direkt auf die Zwischenplatine einwirkende Druckplatine die Positionierungsfunktion übernimmt.According to a variant of CH-PS 517 853, the pressure element does not act directly on the elastic, flexible circuit board, but on a resilient intermediate circuit board. This has a hairpin-shaped end section and is slidably mounted between a bar and the bottom of the needle channel. To actuate the intermediate board, two pressure boards are necessary, the intermediate board taking over the spring function, the pressure board acting directly on the intermediate board taking over the positioning function.

Der Erfinder hat sich die Aufgabe gestellt, eine Strick­maschine, insbesondere eine Flachstrickmaschine, der ein­gangs genannten Art mit einer in einem Nadelkanal eines Nadelbetts mittels einer Steuerplatine längsverschiebbar gelagerten, selbstfedernden Zwischenplatine mit einem Drückerfuss zu schaffen, welche kostengünstiger herzustel­len und zu betreiben ist, einfacher arbeitet und weniger störungsanfällig ist.The inventor has set himself the task of creating a knitting machine, in particular a flat knitting machine, of the type mentioned at the beginning with a self-resilient intermediate plate mounted in a needle channel of a needle bed by means of a control plate and which is longitudinally displaceable and which works with a presser foot, which is more cost-effective to produce and operate and is less prone to failure.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die längsverschiebbare Zwischenplatine federnd zwischen dem Bo­den des Nadelkanals und der Unterseite eines Steuerplati­nenbetts gespannt ist, und die Zwischenplatine sowie der Boden des Nadelkanals und/oder das Steuerplatinenbett Mit­tel zur Positionierung der Zwischenplatine in deren Längs­richtung aufweisen.The object is achieved in that the longitudinally displaceable intermediate plate is resiliently stretched between the bottom of the needle channel and the underside of a control board bed, and the intermediate board and the bottom of the needle channel and / or the control board bed have means for positioning the intermediate board in its longitudinal direction.

Mit einer positionierbaren Zwischenplatine wird an Stelle von zwei Druckplatinen (CH-PS 517 853) nur noch eine ver­wendet, im vorliegenden Fall Steuerplatine genannt. Es liegt auf der Hand, dass die Einsparung eines Druckteils in jedem Nadelkanal die Investitionskosten verkleinert, den Betrieb vereinfacht und dadurch ebenfalls kostengünstiger gestaltet, sowie die Störungsanfälligkeit erniedrigt wird.With a positionable intermediate board, only one is used instead of two pressure boards (CH-PS 517 853), in the present case called control board. It is obvious that the saving of a pressure part in each needle channel reduces the investment costs, simplifies the operation and thereby also makes it more cost-effective, and reduces the susceptibility to faults.

Die Selbstfederung der Zwischenplatine wird dadurch er­reicht, dass das vom Drückerfuss abgewandte Ende in an sich bekannter Weise haarnadelförmig oder Z-förmig umgebogen ist. An der dem Boden des Nadelkanals und/oder der Unter­seite des Steuerplatinenbetts zugewandten Aussenfläche der Zwischenplatine ist vorzugsweise eine in Querrichtung ver­laufende Einkerbung ausgebildet.The self-suspension of the intermediate plate is achieved in that the end facing away from the presser foot in itself is bent in a known manner hairpin or Z-shaped. A notch extending in the transverse direction is preferably formed on the outer surface of the intermediate board facing the bottom of the needle channel and / or the underside of the control board bed.

Am Boden des Nadelkanals und/oder am Steuerplatinenbett sind bevorzugt wenigstens zwei, insbesondere drei, in eine Einkerbung der Zwischenplatine eingreifende Rastrierungen ausgebildet. Zur Erleichterung der Verschiebung der Zwi­schenplatine sind die ihr zugewandten Rastrierungen zweck­mässig rund, abgerundet oder abgeschrägt ausgebildet.At least two, in particular three, detents which engage in a notch in the intermediate board are preferably formed on the bottom of the needle channel and / or on the control board bed. In order to facilitate the displacement of the intermediate board, the catches facing it are expediently round, rounded or beveled.

Die Erfindung wird anhand eines in der Zeichnung darge­stellten Ausführungsbeispiels näher erläutert. Es zeigen schematisch:

  • - Fig. 1 einen Schnitt durch den hinteren Teil des Nadel­kanals einer Flachstrickmaschine mit Platinen, Kupplungsteil und einem Teil der Nadel,
  • - Fig. 2 eine vergrösserte Darstellung der Positionie­rungsvorrichtung für die Zwischenplatine.
The invention is explained in more detail using an exemplary embodiment shown in the drawing. They show schematically:
  • 1 shows a section through the rear part of the needle channel of a flat knitting machine with sinkers, coupling part and part of the needle,
  • - Fig. 2 is an enlarged view of the positioning device for the intermediate board.

Der in Fig. 1 dargestellte, vertikale Teilschnitt durch einen Nadelkanal 10 eines Nadelbetts zeigt alle funktionel­len Teile, wobei die Nadel 12 nur teilweise dargestellt ist. Der Nadelschaft ist abgeschnitten, der Nadelkopf mit der Zunge ist - weil in üblicher Bauart ausgeführt - nicht dargestellt. Der Boden 14 des Nadelkanals ist im Bereich der von Begrenzungsleisten 13 geführten Nadel 12 dicker ausgebildet als an dessen hinterem Ende.The vertical partial section shown in FIG. 1 through a needle channel 10 of a needle bed shows all functional parts, the needle 12 being shown only partially. The needle shaft is cut off, the needle head with the tongue is not shown because it is of a conventional design. The bottom 14 of the needle channel is thicker in the area of the needle 12 guided by the limiting strips 13 than at the rear end thereof.

Der Kupplungsteil 16 stützt einends mit dem Kupplungskopf 18 in einer entsprechenden Aussparung im Schaft der Nadel 12 und andernends auf dem Boden 14 des Nadelkanals 10 ab. Der Kupplungsteil 16 ist elastisch biegsam ausgebildet und kann mit kleinem Kraftaufwand aus dem Durchlaufkanal 20 im Schlossteil 23 der Strickschlossplatte 22 entfernt werden. Der Arbeitsfuss 24 ist in dieser, in Fig. 1 dargestellten Position dem führenden Einfluss des Durchlaufskanals 20 bzw. dem Schlossteil 23 ganz allgemein entzogen, die aus­schliesslich vom Arbeitsfuss 24 in die Strick- oder Um­hängeposition gebrachte Nadel bleibt beim Schlittendurch­gang in Ruhelage.The coupling part 16 is supported at one end with the coupling head 18 in a corresponding recess in the shaft of the needle 12 and at the other end on the bottom 14 of the needle channel 10. The coupling part 16 is designed to be elastic and flexible can be removed from the pass-through channel 20 in the lock part 23 of the knitted lock plate 22 with little effort. In this position, shown in FIG. 1, the working foot 24 is generally removed from the leading influence of the flow channel 20 or the lock part 23, the needle brought exclusively from the working foot 24 into the knitting or transferring position remains in the rest position during the carriage passage.

Die Zwischenplatine 26 liegt einends auf dem Kupplungsteil 16 auf. Das andere Ende der Zwischenplatine 26 ist haarna­delförmig umgebogen und stützt mit einem umgebogenen Schen­kel 28 auf dem Boden 14 des Nadelkanals 10 ab. Die Zwi­schenplatine 26 ist zwischen den Boden 14 und die Untersei­te 31 des Steuerplatinenbetts 30 gespannt.The intermediate board 26 rests on the coupling part 16 at one end. The other end of the intermediate board 26 is bent in a hairpin shape and is supported with a bent leg 28 on the bottom 14 of the needle channel 10. The intermediate board 26 is stretched between the bottom 14 and the underside 31 of the control board bed 30.

Ein Begrenzungsdraht 62, in einer Nut 64 angeordnet, be­grenzt den Bewegungsraum des Kupplungsteils 16 und der Zwischenplatine 26.A boundary wire 62, arranged in a groove 64, limits the movement space of the coupling part 16 and the intermediate board 26.

Die Zwischenplatine 26 ist positionierbar, der dem Steuer­platinenbett 30 zugewandte Schenkel 32 hat auf der Aussen­seite eine in Querrichtung verlaufende Einkerbung 34, in welche einer von drei über die ganze Länge des Nadelbetts gespannten Drähten 36 einrastet. Diese Positionierungsvor­richtung ist in Fig. 2 im Detail dargestellt, wo auch die Verstärkung des Schenkels 32 bei der Einkerbung 34 gut erkennbar ist.The intermediate board 26 can be positioned, the leg 32 facing the control board bed 30 has on the outside a transverse notch 34 into which one of three wires 36 which are stretched over the entire length of the needle bed engages. This positioning device is shown in detail in FIG. 2, where the reinforcement of the leg 32 in the notch 34 is also clearly visible.

Im Bereich des auf den Kupplungsteil 16 aufliegenden Endes der Zwischenplatine 26 kragt in Richtung der Strickschloss platte 22 der Drückerfuss 38 ab, welcher in der gezeichne­ten Lage wie der Arbeitsfuss 24 ausserhalb des Wirkungsbe­reichs der Strickschlossplatte 22 ist.In the area of the end of the intermediate plate 26 resting on the coupling part 16, the pusher foot 38 protrudes in the direction of the knitted lock plate 22, which in the position shown is like the working foot 24 outside the effective range of the knitted lock plate 22.

Die um eine Achse A schwenkbare Steuerplatine 40 wird von einer Blattfeder 42 in Uhrzeigerrichtung gedreht, sobald die Wirkung des Magneten 44 auf ihr äusseres Ende 46 ent­fällt. Dieser Magnet 44 besteht - in Fig. 1 nicht sichtbar - aus einem Dauermagneten, der in bezug auf seine Wirkung auf die Steuerplatine 40 elektromagnetisch neutralisiert werden kann. In der mit Normalstrich gezeigten Position ist der Elektromagnet eingeschaltet, die Steuerplatine 40 ist abgeworfen. In der punktierten Lage ist der Elektromagnet ausgeschaltet, das äussere Ende 46 der Steuerplatine 40 wird vom nicht neutralisierten Dauermagneten gehalten.The control board 40, which can be pivoted about an axis A, is rotated clockwise by a leaf spring 42 as soon as the effect of the magnet 44 on its outer end 46 is eliminated. This magnet 44 - not visible in FIG. 1 - consists of a permanent magnet which can be electromagnetically neutralized with regard to its effect on the control board 40. In the position shown with a normal line, the electromagnet is switched on, the control board 40 is ejected. In the dotted position the electromagnet is switched off, the outer end 46 of the control board 40 is held by the non-neutralized permanent magnet.

In der in Fig. 1 dargestellten Position wird der Steuerfuss 48 der Steuerplatine 40 vom Schlossteil 50 der Steuer­schlossplatte 52 geführt, sobald die Führungsfläche 54 die entsprechend ausgebildete Fläche des Steuerfusses 48 er­reicht hat.In the position shown in FIG. 1, the control foot 48 of the control board 40 is guided by the lock part 50 of the control lock plate 52 as soon as the guide surface 54 has reached the correspondingly designed surface of the control foot 48.

Der einseitig von einer Steuerfläche geführte Hilfsteuer­fuss 56 dient in erster Linie dem Weitertransport und der Rückführung der Steuerplatine 40 mittels des Schlossteils 58. Die Bewegungsfreiheit der Steuerplatine 40 wird in Längsrichtung durch Begrenzungsleisten 59 geschränkt.The auxiliary control foot 56, which is guided on one side by a control surface, is used primarily for the further transport and return of the control board 40 by means of the lock part 58. The freedom of movement of the control board 40 is restricted in the longitudinal direction by limiting strips 59.

Sowohl die Steuerplatine 40 als auch die Zwischenplatine 26 werden nach jeder Arbeitsphase in die - in bezug auf die Längsrichtung des Nadelkanals 10 - in Fig. 1 dargestellte Ruhestellung zurückgeführt.Both the control board 40 and the intermediate board 26 are returned to the rest position shown in FIG. 1 with respect to the longitudinal direction of the needle channel 10 after each working phase.

Die Nadel 12 wird ausschliesslich durch die Bewegungsüber­tragung auf den Arbeitsfuss 24 geführt, wenn dieser in die Strickschlossplatte 22 bzw. deren Schlossteile 23 ein­greift. Dies erfolgt, wenn der stets leicht gespannte Kupp­lungsteil 16 nicht von der Zwischenplatine 26 nach unten, in die Position Nichtstricken, gedrückt wird. Vom Strick­schloss kann die Nadel 12 in die Positionen Stricken, Fan­gen, Uebergabe oder Uebernahme geführt werden.The needle 12 is guided exclusively by the movement transmission on the working foot 24 when it engages in the knitted lock plate 22 or its lock parts 23. This takes place when the coupling part 16, which is always slightly tensioned, is not pressed downward by the intermediate plate 26 into the non-knitting position. The needle 12 can be guided from the knitting lock to the knitting, catching, transfer or transfer positions.

Die Zwischenplatine 26 ist derart gespannt, dass der Drüc­ kerfuss 38 ohne Fremdeinwirkung in eine Ausnehmung der Strickschlossplatte 22 bzw. von deren Schlossteilen 23 ge­führt wird, sobald der Weg frei ist.The intermediate board 26 is tensioned such that the pressure Kerfuss 38 is guided without outside influence into a recess in the knitted lock plate 22 or from its lock parts 23 as soon as the path is free.

Eine abgeworfene Steuerplatine 40 kann vom Schlossteil 50 durch Einwirkung auf den Steuerfuss 48 derart verschoben werden, dass die mitverschobene Nase 60 nach dem Ueberwin­den des Spiels von beispielsweise 7 mm die Zwischenplatine 26 ihrerseits derart verschiebt, dass der Drückerfuss 38 die Ruheposition I verlässt und die Position II oder III erreicht. Exakt in der Position II rastet der mittlere Draht 36 (Fig. 2) in der Einkerbung 34 der Zwischenplatine 26 ein, in der Position III des Drückerfusses rastet der rechte Draht 36 ein. Aus diesem Beispiel wird die wesentli­che Bedeutung des Rasters für die Positionierung der Zwi­schenplatine 26 deutlich.A thrown control board 40 can be moved by the lock part 50 by acting on the control foot 48 such that the nose 60 which has also been displaced after overcoming the play of, for example, 7 mm, displaces the intermediate board 26 in such a way that the presser foot 38 leaves the rest position I and the position II or III reached. Exactly in position II, the middle wire 36 (FIG. 2) snaps into the notch 34 of the intermediate board 26, in position III of the presser foot the right wire 36 snaps into place. From this example, the essential meaning of the grid for the positioning of the intermediate board 26 becomes clear.

Die Position I für den Drückerfuss 38, die Ruheposition, ist stets eine im Strickschloss senkrecht zum Nadelkanal 10 verlaufende Bahn, der Arbeitsfuss 24 der Nadeln 12 bleibt in dieser Position ausserhalb des Wirkungsbereichs von zu Nadelbewegungen führenden Schlossteilen 23 der Strickschlossplatte 22.The position I for the presser foot 38, the rest position, is always a path running perpendicular to the needle channel 10 in the knitting lock, the working foot 24 of the needles 12 remains in this position outside the effective range of lock parts 23 of the knitting lock plate 22 leading to needle movements.

In der Position II für den Drückerfuss 38 wird der Arbeits­fuss 24 des Kupplungsteils 16 durch die Zwischenplatine 26 so verschoben, dass er beim Eingriff in einen Durchlaufka­nal 20 der Strickschlossplatte 22 bzw. in deren Schlosstei­le 23 die Nadel 12 in die Uebergabe- oder Strickposition führt.In position II for the presser foot 38, the working foot 24 of the coupling part 16 is displaced by the intermediate plate 26 in such a way that it engages the needle 12 into the transfer or knitting position when it engages in a passageway 20 of the knitted lock plate 22 or in its lock parts 23.

Verschiebt die Steuerplatine 40 den Drückerfuss 38 der Zwi­schenplatine 26 in die Position III, so wird der Arbeits­fuss 24 des Kupplungsteils 16 so positioniert, dass die Na­del 12 beim Einrasten in der Strickschlossplatte 22 in Uebernahme- oder Fangposition geführt wird.If the control board 40 moves the presser foot 38 of the intermediate board 26 into position III, the working foot 24 of the coupling part 16 is positioned such that the needle 12 is guided into the take-over or catching position when it snaps into the knitted lock plate 22.

Die Aussparungen in der Strickschlossplatte 22 bzw. in de­ren Schlossteilen 23 sind so angefertigt, dass der Drücker­fuss 38 von der Ruheposition I in eine Arbeitsposition II oder III gebracht werden kann, ohne dass er abgesenkt wer­den muss.The cutouts in the knitted lock plate 22 or in its lock parts 23 are made in such a way that the presser foot 38 can be brought from the rest position I into a working position II or III without having to be lowered.

In den Arbeitspositionen II und III können in an sich be­kannter Weise - in Richtung der Schlittenbewegung - Drüc­kerleisten in den Schlossteilen 23 einer Strickschlossplat­te 22 derart montiert sein, dass die Drückerfüsse 38, und damit auch die Arbeitsfüsse 24, ausserhalb des Wirkungsbe­reichs der in Richtung des Nadelkanals 10 wirkenden Be­standteile der Strickschlossplatte 22 bzw. deren Schloss­teile 23 geraten, was die Stillegung der entsprechenden Na­deln 12 bedeutet. Dies bietet also neben dem individuellen Festlegen des äusseren Endes 46 von Steuerplatinen 40 auf dem zugeordneten Magneten 44 eine zweite Möglichkeit, die Nadeln einzeln oder gruppenweise ausser Funktion zu setzen, womit verschiedene Strickmuster herstellbar sind.In the working positions II and III, in a manner known per se - in the direction of the slide movement - pusher bars can be mounted in the lock parts 23 of a knitted lock plate 22 in such a way that the presser feet 38, and thus also the working feet 24, are outside the range of action in the direction of the needle channel 10 acting components of the knitting lock plate 22 or its lock parts 23, which means the closure of the corresponding needles 12. In addition to the individual fixing of the outer end 46 of control boards 40 on the associated magnet 44, this therefore offers a second possibility of deactivating the needles individually or in groups, with which different knitting patterns can be produced.
