Description

Die Erfindung bezieht sich auf eine Flachstrickmaschine mit über deren Nadelbetten bewegbarer Nadelauswahleinrichtung, in Nadelkanälen der Nadelbetten angeordneten Stricknadeln und an die Stricknadeln in den Nadelkanälen anschließenden Auswahlstößern oder hintereinander anschließenden Arbeitsstößern und Auswahlstößern, die mit der Nadelauswahleinrichtung zusammenarbeiten.The invention relates to a flat knitting machine with a needle selection device which can be moved over the needle beds, knitting needles arranged in needle channels of the needle beds and selection beaters connected to the knitting needles in the needle channels or successive work bumpers and selection bumpers which cooperate with the needle selection device.

Jede Betätigung der Stößer bedarf einer Kraft, deren Größe zunächst abhängig vom Gewicht der Stößer ist. Damit die Stößer beim Bewegen durch die Auswahlschloßteile nicht springen, werden sie mehr oder weniger stark gebremst. Eine solche Bremswirkung ist u.a. durch seitliches Verbiegen der Stößer aus ihrer Längsachse zu erreichen. Wichtig ist dabei, daß die Federkennlinie der Verbiegung flach verläuft, so daß die Bremswirkung der Verbiegung auf die Stößer nicht hart, sondern weich ist. Eine weitere Maßnahme zum Vermeiden des Springens der Stößer besteht darin, die Auftriebsschrägen der Auswahlschloßteile, insbesondere bei schnell laufenden Flachstrickmaschinen, flach auszubilden, so daß die Beschleunigung der Stößer entsprechend niedrig gehalten werden kann.Each actuation of the pushers requires a force, the size of which depends on the weight of the pushers. So that the bumpers do not jump when moving through the selection lock parts, they are braked to a greater or lesser extent. Such a braking effect includes to achieve by bending the pusher sideways from its longitudinal axis. It is important that the spring characteristic of the bend runs flat, so that the braking effect of the bend on the bumpers is not hard, but soft. A further measure for avoiding the bouncing of the bumpers is to make the lift slopes of the selection lock parts flat, particularly in the case of fast-running flat knitting machines, so that the acceleration of the bumpers can be kept correspondingly low.

Bei den unterschiedlichen Feinheiten von Flachstrickmaschinen sind unterschiedlich breite Nadelkanäle vorgesehen und werden dementsprechend unterschiedlich breite Stößer benötigt. Um nun bei den unterschiedlichen Feinheiten die gleichmäßige Elastizität in der Bremskraft durch seitliches Verbiegen der Stößer zu erreichen, erhalten die Stößer grober Feinheiten unterschiedlich tiefe Aussparungen, so daß die verbleibende Schaftdicke im Bereich der Verbiegung bei den unterschiedlichen Feinheiten gleichbleibt. So ergibt sich zwar eine gleichbleibende Federkennlinie, der Schleudereffekt ist jedoch, je nach Gewicht der Stößer, immer noch unterschiedlich.In the different subtleties of flat knitting machines, needle channels of different widths are provided and, accordingly, different widths of pushers are required. In order to achieve the uniform elasticity in the braking force by bending the bumpers laterally in the different subtleties, the bumpers have coarse subtleties of different depths, so that the remaining shaft thickness remains the same in the bending with the different subtleties. This results in a constant spring characteristic, but the skidding effect is still different, depending on the weight of the pushers.

Durch die CH-PS 369 854 ist es bekannt geworden, beide Seitenwände der Nadelkanäle durch fest in das Nadelbett eingebaute, über dessen gesamte Breite verlaufende, elastisch verformbare Führungsplatinen auszukleiden. Die Nadelkanäle sind auch hier bei unterschiedlichen Feinheiten unterschiedlich breit.From CH-PS 369 854 it has become known to line both side walls of the needle channels by means of guide plates which are built into the needle bed and extend over its entire width and are elastically deformable. Here, too, the needle channels are of different widths with different finenesses.

Der Erfindung liegt die Aufgabe zugrunde, eine Flachstrickmaschine der eingangs beschriebenen Art zu schaffen, bei der die Stößer bei unterschiedlichen Feinheiten der Maschine sowohl eine gleichmäßige Elastizität in der Bremskraft als auch gleiche Gewichte und somit einen gleichen Schleudereffekt aufweisen.The invention has for its object to provide a flat knitting machine of the type described in the introduction, in which the pushers have different elasticities in the machine, as well as uniform elasticity in the braking force and the same weights and thus the same skidding effect.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Breite der Arbeitsstößer und/oder Auswahlstößer kleiner als die Breite der Nadelkanäle ist, und daß in die Nadelkanäle sich im wesentlichen über die Länge der Arbeitsstößer und/oder Auswahlstößer erstreckende Distanzplatinen mit einer Breite gleich der Differenz der Breite der Nadelkanäle und der Breite der Arbeitsstößer und/oder Auswahlstößer fixiert wenigstens auf einer Seite der Stößer eingelegt sind.This object is achieved in that the width of the working ram and / or selection ram is smaller than the width of the needle channels, and that in the needle channels extending spacers substantially over the length of the ram and / or selection ram with a width equal to the difference of Width of the needle channels and the width of the ram and / or ram are fixed at least on one side of the ram.

Damit läßt sich die Breite der Arbeits- und Auswahlstößer unabhängig von der Feinheit der Flachstrickmaschine und von der Breite ihrer Nadelkanäle wählen und somit ihr Gewicht festlegen. Die Distanzplatinen sind in den Nadelkanälen fixiert und tragen zum Bewegungs- und Bremsverhalten der Stößer nicht ausschlaggebend bei.This means that the width of the work and selection rams can be selected independently of the fineness of the flat knitting machine and the width of its needle channels and thus determine its weight. The spacer boards are fixed in the needle channels and do not make a decisive contribution to the movement and braking behavior of the pushers.

Vorteilhaft ist bei entsprechend der Feinheit der Flachstrickmaschine ausgebildeter Breite der Nadelkanäle und der Stricknadeln die Breite der Arbeitsstößer und/oder Auswahlstößer einheitlich konstant und die Breite der Distanzplatinen dementsprechend für unterschiedliche Feinheiten der Flachstrickmaschine unterschiedlich. Hiermit lassen sich über einen weiten Bereich unterschiedlicher Feinheiten Arbeitsstößer und/oder Auswahlstößer konstanter Gewichte und damit gleichmäßigen Brems- und Springverhaltens erreichen. Für die unterschiedlichen Feinheiten der Flachstrickmaschine sind Stößer nur einer einzigen Dicke vorzusehen, der Ausgleich zu den unterschiedlichen Nadelkanalbreiten erfolgt durch die fixiert eingelegten Distanzplatinen.When the width of the needle channels and the knitting needles is designed in accordance with the fineness of the flat knitting machine, the width of the working rams and / or selection rams is advantageously uniform and the width of the spacer plates correspondingly different for different finenesses of the flat knitting machine. This makes it possible to achieve ramblers and / or ramblers of constant weights and thus uniform braking and jumping behavior over a wide range of different finenesses. For the different subtleties of the flat knitting machine, butt joints of only a single thickness are to be provided, and the different needle channel widths are compensated for by the fixed spacer plates.

Zweckmäßig verlaufen die Oberflächen der Distanzplatinen in und unterhalb der Oberflächen der Nadelbetten, unterhalb der Oberflächen dort, wo Halteschienen zum Halten von Stricknadeln und Stößern in den Nadelbetten vorgesehen sind.The surfaces of the spacer boards expediently run in and below the surfaces of the needle beds, below the surfaces where holding rails for holding knitting needles and pushers are provided in the needle beds.

Vorteilhaft ist jeweils eine einzige Distanzplatine entlang der Länge von Arbeitsstößer und Auswahlstößer in den Nadelkanal eingelegt. Dies erleichtert sowohl die Herstellung als auch das Einlegen und Fixieren der Distanzplatinen im Nadelkanal.A single spacer plate is advantageously inserted into the needle channel along the length of the working ram and the selection ram. This facilitates both the manufacture and the insertion and fixing of the spacer boards in the needle channel.

Zweckmäßig ist jede Distanzplatine durch eine quer zu den Nadelkanälen im Nadelbett verlaufende Schiene formschlüssig in Bewegungsrichtung der Arbeitsstößer und/oder Auswahlstößer fixiert.Each spacer plate is expediently fixed in the direction of movement of the working pushers and / or selection pushers by a rail running transversely to the needle channels in the needle bed.

Die Distanzplatine ist bei entsprechender Ausbildung der Stricknadel vorteilhaft derart ausgebildet, daß sie diese im Bereich des Arbeits- oder Auswahlstößers teilweise übergreift.With a corresponding design of the knitting needle, the spacer plate is advantageously designed such that it partially engages over it in the area of the working or selection ram.

Die Distanzplatinen sind zweckmäßig nur auf einer Seite der Arbeitsstößer und/oder Auswahlstößer eingelegt. Alternativ können die Distanzplatinen auch auf beiden Seiten der Arbeitsstößer und/oder Auswahlstößer eingelegt sein, was insbesondere bei groben Feinheiten der Flachstrickmaschine vorteilhaft sein kann.The spacer boards are expediently inserted only on one side of the work pushers and / or selection pushers. Alternatively, the spacer plates can also be inserted on both sides of the ram and / or ram, which can be particularly advantageous in the case of coarse subtleties of the flat knitting machine.

Bei einer Feinheit E3 der Flachstrickmaschine beträgt beispeilsweise zweckmäßig die Breite der Stricknadeln 2,2 mm, die Breite der Arbeitsstößer und/oder Auswahlstößer 1 mm und die Breite der Distanzplatinen 1,2 mm.With a fineness E3 of the flat knitting machine, for example, the width of the knitting needles is expediently 2.2 mm, the width of the working rams and / or selection rams is 1 mm and the width of the spacer boards is 1.2 mm.

Die Erfindung ist im folgenden an einem Ausführungsbeispiel und anhand der Zeichnung näher erläutert. In der Zeichnung zeigen

  • Fig. 1 einen Querschnitt durch ein Nadelbett einer Flachstrickmaschine mit eingelegten Stößern und Distanzplatine gemäß der Erfindung, geschnitten längs der Linie 1-1 in Fig. 3,
  • Fig. 2 einen Querschnitt wie in Fig. 1, jedoch geschnitten längs der Linie 11-11 in Fig. 3, und
  • Fig. 3 eine Draufsicht auf einen Teil eines Nadelbetts nach Fig. 1.
The invention is explained below using an exemplary embodiment and with reference to the drawing. Show in the drawing
  • 1 shows a cross section through a needle bed of a flat knitting machine with inserted pushers and spacer plate according to the invention, cut along the line 1-1 in FIG. 3,
  • Fig. 2 shows a cross section as in Fig. 1, but cut along the line 11-11 in Fig. 3, and
  • 3 is a plan view of part of a needle bed according to FIG. 1.

Wie in den Fig. 1 bis 3 dargestellt, weist ein Nadelbett 1 einer Flachstrickmaschine entsprechend der Feinheit der Flachstrickmaschine angeordnete und ausgebildete Nadelkanäle 2 auf. In jedem Nadelkanal ist eine Stricknadel 3 und anschließend an diese ein Arbeitsstößer 4 angeordnet. Der Arbeitsstößer 4 stößt lösbar an die Stricknadel 3 an und übergreift diese teilweise. Hinter dem Arbeitsstößer ist ein an diesen lösbar anstoßender Auswahlstößer 5 im Nadelkanal 2 angeordnet. Arbeitsstößer 4 und Auswahlstößer 5 können auch zu einem einstückigen Auswahlstößer zusammengefaßt sein.As shown in FIGS. 1 to 3, a needle bed 1 of a flat knitting machine has needle channels 2 arranged and designed in accordance with the fineness of the flat knitting machine. A knitting needle 3 and then a ram 4 are arranged in each needle channel. The ram 4 releasably abuts the knitting needle 3 and partially overlaps it. A selection ram 5, which is detachably abutting the ram, is arranged in the needle channel 2 behind the ram. Pusher 4 and selection pusher 5 can also be combined into a one-piece selection pusher.

Die Stricknadeln 3, Arbeitsstößer 4 und Auswahlstößer 5 sind durch quer zu den Nadelkanälen 2 verlaufende Schienen 6, 7, 8 in den Nadelkanälen 2 des Nadelbetts 1 gehalten.The knitting needles 3, working ram 4 and selection ram 5 are held in the needle channels 2 of the needle bed 1 by rails 6, 7, 8 running transversely to the needle channels 2.

Auf einer Seite der Arbeitsstößer 4 und Auswahlstößer 5 ist eine sich im wesentlichen über die Länge der Arbeitsstößer 4 und Auswahlstößer 5 erstreckende Distanzplatine 9 eingelegt. Die Distanzplatine 9 ist in Fig. 1 zur besseren Heraushebung senkrecht schraffiert. Durch die quer zu den Nadelkanälen 2 verlaufende Schiene 7, die in eine entsprechende Rechtecknut der Distanzplatine 9 eingreift, ist die Distanzplatine 9 formschlüssig in Bewegungsrichtung der Arbeitsstößer 4 und Auswahlstößer 5 fixiert und nimmt damit an den Hin-und Herbewegungen des Arbeitsstößers 4 und des Auswahlstößers 5 unter dem Einfluß der nicht dargestellten Nadelauswahleinrichtung nicht teil.On one side of the working plunger 4 and selection plunger 5, a spacer plate 9 is inserted which extends essentially over the length of the working plunger 4 and selection plunger 5. The spacer plate 9 is hatched vertically in Fig. 1 for better lifting. Due to the rail 7 running transversely to the needle channels 2, which engages in a corresponding rectangular groove of the spacer plate 9, the spacer plate 9 is fixed in a positive manner in the direction of movement of the working plunger 4 and the selection plunger 5 and thus takes part in the back and forth movements of the working plunger 4 and the selection plunger 5 under the influence of the needle selection device, not shown.

Die Breite der Arbeitsstößer 4 und Auswahlstößer 5 kann nun so gewählt werden, daß sie beispielsweise der Breite eines Nadelkanals 2 für die feinste gewünschte Feinheit einer Flachstrickmaschine entspricht. Für gröbere Feinheiten der Flachstrickmaschine wird dann der Breitenunterschied zwischen Nadelkanalbreite und Stößerbreite durch die entsprechend gewählte Breite der feststehenden, an der Stößerbewegung nicht teilnehmenden Distanzplatinen 9 ausgeglichen. Das Gewicht der Arbeitsstößer 4 und Auswahlstößer 5 kann somit unabhängig von der Teilung oder Feinheit der Flachstrickmaschine immer gleich bleiben.The width of the ram 4 and ram 5 can now be selected so that it corresponds, for example, to the width of a needle channel 2 for the finest desired fineness of a flat knitting machine. For coarser subtleties of the flat knitting machine, the width difference between the needle channel width and the ram width is then compensated for by the correspondingly selected width of the fixed spacer plates 9, which do not participate in the ram movement. The weight of the ram 4 and ram 5 can thus always remain the same regardless of the pitch or fineness of the flat knitting machine.

Statt der in der Zeichnung dargestellten, sich im wesentlichen über die gesamte Länge von Arbeitsstößer 4 und Auswahlstößer 5 erstreckenden Distanzplatine 9 können auch zwei hintereinander angeordnete Distanzplatinen verwendet werden, die sich jeweils im wesentlichen über die Länge des Arbeitsstößers 4 und im wesentlichen über die Länge des Auswahlstößers 5 erstrecken. In der Zeichnung ist eine Distanzplatine 9 auf einer Seite des Arbeitsstößers 4 und des Auswahlstößers 5 in den Nadelkanal 2 eingelegt gezeigt. Es kann jedoch auch vorteilhaft sein, auf den beiden Seiten der Arbeitsstößer 4 und der Auswahlstößer 5 je eine Distanzplatine in jeden Nadelkanal 2 einzulegen.Instead of the spacer plate 9 shown in the drawing, which extends essentially over the entire length of the working plunger 4 and the selection plunger 5, it is also possible to use two spacing boards arranged one behind the other, each essentially over the length of the working plunger 4 and essentially over the length of the Range 5 extend. In the drawing, a spacer plate 9 is shown inserted into the needle channel 2 on one side of the working ram 4 and the selection ram 5. However, it can also be advantageous to insert a spacer plate in each needle channel 2 on the two sides of the working ram 4 and the selection ram 5.

Entsprechend einer beispielsweise angegebenen konkreten Ausführungsform der Flachstrickmaschine ist der Nadelkanal 2 bei einer Feinheit E3 der Flachstrickmaschine 2,2 mm breit. Die Stricknadel 3 hat eine Breite von 2,2 mm, und die hinter der Stricknadel 3 angeordneten Arbeitsstößer 4 und Auswahlstößer 5 werden 1 mm dick ausgeführt. Die sich in diesem Fall über den Bereich des Arbeitsstößers 4 und des Auswahlstößers 5 erstreckende Distanzplatine 9 hat dann eine Breite von 1,2 mm entsprechend der Differenz zwischen Nadelkanalbreite und Stößerbreite. Hierdurch wird das Gewicht der arbeitenden Stößer 4 und 5 nur etwa 45% bezogen auf das Gewicht herkömmlicher Stößer mit einer Dicke von 2,2, mm sein. Entsprechend dieser Gewichtsverringerung werden die Arbeitsstößer 4 und Auswahlstößer 5 bei Bewegungsbeginn im Zusammenarbeiten mit der Nadelauswahleinrichtung weniger stark springen.According to a specific embodiment of the flat knitting machine specified, for example, the needle channel 2 is 2.2 mm wide with a fineness E3 of the flat knitting machine. The knitting needle 3 has a width of 2.2 mm, and the working rams 4 and selection rams 5 arranged behind the knitting needle 3 are made 1 mm thick. The spacer plate 9, which in this case extends over the area of the working ram 4 and the selection ram 5, then has a width of 1.2 mm, corresponding to the difference between the needle channel width and the ram width. As a result, the weight of the working pushers 4 and 5 will only be about 45% based on the weight of conventional pushers with a thickness of 2.2 mm. In accordance with this reduction in weight, the working pushers 4 and selection pushers 5 will jump less strongly at the start of the movement in cooperation with the needle selection device.
