Description

Flachstrickmaschine mit Toleranzausgleich für die StricknadeFlat knitting machine with tolerance compensation for the knitting needle
BESCHREIBUNG:DESCRIPTION:
Die Erfindung bezieht sich auf eine Flachstrickmaschine mit einander gegenüber angeordneten Nadelbetten und mit in Nadelkanälen der Nadelbetten angeordneten Stricknadeln, die mittels quer zu den Nadelkanälen verlaufenden Nadeldeckschienen über den Stricknadeln auf dem Nadelkanalgrund liegend gehalten sind.The invention relates to a flat knitting machine with needle beds arranged opposite one another and with knitting needles arranged in needle channels of the needle beds, which are held lying above the knitting needles on the needle channel base by means of needle cover rails extending transversely to the needle channels.
In jeder Flachstrickmaschine sind der Nadelteilung und der Arbeitsbreite entsprechend mehr oder weniger Stricknadeln vorhanden. Diese Stricknadeln, mit denen Maschen gestrickt bzw. Maschen umgehängt werden, müssen in ihren Nadelkanälen einwandfrei geführt werden. Dies ist besonders wichtig beim Umhängen mit feinen Stricknadeln, d.h. mit Stricknadeln beispielsweise ab der Feinheit E12. Die Stricknadeln müssen auf dem Nadelkanalgrund liegen, damit zum Maschenübernehmen ausgewählte Stricknadeln mit ihren kleinen Nadelhaken in zum Übergeben vorgelegte Maschen einfädeln können und damit bei eventuell geschlossenem Nadelkopf die zu übergebende Masche die Nadelzunge der übernehmenden Stricknadel sicher öffnet.Each flat knitting machine has more or fewer knitting needles depending on the needle pitch and the working width. These knitting needles, which are used to knit stitches or to transfer stitches, must be properly guided in their needle channels. This is particularly important when putting on fine knitting needles, i.e. with knitting needles, for example, from the fineness E12. The knitting needles must lie on the needle channel base so that selected knitting needles can be threaded with their small needle hooks into stitches submitted for transfer and so that, if the needle head is closed, the stitch to be transferred securely opens the needle tongue of the knitting needle to be taken over.
Durch eine Summe von Fertigungstoleranzen ist dies nicht immer garantiert. Die Stricknadeln, die von der Nadeldeckschiene im Nadelkanalgrund gehalten werden, haben über die Arbeitsbreite verteilt unterschiedliche Toleranzspiele. Das größte Toleranzspiel - maximal etwa - .1 -A sum of manufacturing tolerances does not always guarantee this. The knitting needles, which are held in the needle channel base by the needle cover rail, have different tolerance clearances across the working width. The biggest tolerance game - maximum about - .1 -
0,1 mm - kann so groß sein, daß leere Stricknadeln, die Maschen übernehmen sollen, nicht auf dem Nadelkanalgrund liegen, sondern sich an der Nadeldeckschiene anlegen und in dieser Position dann nicht mehr mit Sicherheit die vorgelegten Maschen übernehmen.0.1 mm - can be so large that empty knitting needles, which are supposed to take over stitches, do not lie on the needle channel base, but lie down on the needle cover rail and in this position then no longer take over the stitches with certainty.
Der Erfindung liegt die Aufgabe zugrunde, eine Flachstrickmaschine der eingangs beschriebenen Art zu schaffen, bei der ein weitgehender Ausgleich von Fertigungstoleranzen der genannten Art und dementsprechend ein sicheres, einwandfreies Führen der Stricknadeln auf dem Nadelkanalgrund liegend möglich ist.The invention has for its object to provide a flat knitting machine of the type described above, in which an extensive compensation of manufacturing tolerances of the type mentioned and accordingly a safe, flawless guiding of the knitting needles lying on the needle channel base is possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß unter der Nadeldeckschiene und über den Stricknadeln längs der Nadeldeckschiene verlaufende Federmittel vorgesehen sind. Die Federmittel bestehen vorteilhaft aus einem harten Federband auf den Stricknadeln und einem im Profil gewölbten, elastisch federnden Stahlband über dem Federband.This object is achieved in that spring means are provided under the needle cover rail and over the knitting needles along the needle cover rail. The spring means advantageously consist of a hard spring band on the knitting needles and an elastically resilient steel band arched in profile over the spring band.
Mit einer derart ausgebildetenWith such a trained
Toleranzausgleichseinrichtung werden die Stricknadeln, unabhängig von unterschiedlichen Toleranzspielen, immer sicher auf den Nadelkanalgrund gedrückt und es ist ein einwandfreies und sicheres Übergeben von Maschen bei jeder beliebigen Feinheit der Nadeln möglich. Das elastisch federnde Stahlband egalisiert über die Arbeitsbreite auftretende Toleranzspiele durch Drücken der Stricknadeln auf den Nadelkanalgrund vollständig. Das Federband kann zweckmäßig ein naturhartes oder ein gehärtetes Federband sein.Tolerance compensation device, the knitting needles, regardless of different tolerance clearances, are always pressed securely onto the needle channel base and it is possible to transfer stitches perfectly and safely with any fineness of the needles. The resilient steel band completely compensates for tolerance play across the working width by pressing the knitting needles onto the needle channel base. The spring band can expediently be a naturally hard or a hardened spring band.
Vorteilhaft ist auf der Unterseite der Nadeldeckschiene eine Langsausnehmung vorgesehen, in der die Federmittel angeordnet sind.A longitudinal recess in which the spring means are arranged is advantageously provided on the underside of the needle cover rail.
Die L ngsausnehmung in der Nadeldeckschiene weist zweckmäßig einen im wesentlichen U-förmigen Querschnitt auf.The longitudinal recess in the needle cover rail expediently has a substantially U-shaped cross section.
Ein Ausführungsbeispiel der Erfindung ist im folgenden anhand der Zeichnung näher beschrieben.An embodiment of the invention is described below with reference to the drawing.
Fig. 1 der Zeichnung zeigt einen Teilquerschnitt durch ein Nadelbett mit erfindungsgemäßem Federmittel.Fig. 1 of the drawing shows a partial cross section through a needle bed with spring means according to the invention.
Das in der Zeichnung dargestellte Nadelbett 1 weist Nadelkanäle 2 auf. In den Nadelkanälen 2 sind auf dem Nadelkanalgrund 3 liegende Stricknadeln 4 angeordnet. Nadelhaken 5 bilden zusammen mit Nadelzungen 6 die Nadelköpfe der Stricknadeln 4.The needle bed 1 shown in the drawing has needle channels 2. Knitting needles 4 lying on the needle channel base 3 are arranged in the needle channels 2. Needle hooks 5 together with needle tongues 6 form the needle heads of the knitting needles 4.
Über den Stricknadeln 4 ist in dem Nadelbett 1 eine quer zu den Nadelkanälen 2 verlaufende Nadeldeckschiene 7 angeordnet, die die Stricknadeln 4 auf dem Nadelkanalgrund 3 liegend und gleitend hält.Arranged above the knitting needles 4 in the needle bed 1 is a needle cover rail 7 which extends transversely to the needle channels 2 and which holds the knitting needles 4 lying and sliding on the needle channel base 3.
In der Unterseite der Nadeldeckschiene 7 ist eine im Querschnitt im wesentlichen U-förmige Langsausnehmung 8 vorgesehen. In der L ngsausnehmung 8 der Nadeldeckschiene liegt auf den Stricknadeln 4 ein gehärtetes oder naturhartes Federband 9 und über diesem ein im Profil gewölbtes, elastisch federndes Stahlband 10. In Fig. 1 ist das Stahlband 10 im entspannten Zustand vor dem Einbau zusätzlich gestrichelt angedeutet.In the underside of the needle cover rail 7 there is a longitudinal recess 8 which is essentially U-shaped in cross section. In the longitudinal recess 8 The needle cover rail lies on the knitting needles 4 with a hardened or naturally hard spring band 9 and, above it, a resilient steel band 10 which is curved in profile, and is shown in FIG. 1 by a dashed line in the relaxed state before installation.
Das elastisch federnde Stahlband 10 drückt über das Federband 9 sämtliche Stricknadeln 4 über die gesamte Arbeitsbreite der Stricknadeln 4 auf deren Nadelkanalgrund 3 und egalisiert so über die Arbeitsbreite auftretende Toleranzspiele bzw. hebt diese völlig auf.The resilient steel band 10 presses all the knitting needles 4 over the entire working width of the knitting needles 4 onto the needle channel base 3 via the spring band 9 and thus equalizes tolerance games that occur over the working width or completely eliminates them.
Es kann somit nicht mehr vorkommen, daß leere Stricknadeln 4, die Maschen übernehmen sollen, nicht auf ihrem Nadelkanalgrund 3 liegen, sondern sich an der Nadeldeckschiene 7 anlegen und in dieser Position dann nicht mit Sicherheit die vorgelegte Masche übernehmen.It can therefore no longer occur that empty knitting needles 4, which are supposed to take over stitches, do not lie on their needle channel base 3, but instead lie on the needle cover rail 7 and then in this position do not take over the stitch provided with certainty.
Auch beim Umhängen mit feinen Stricknadeln 4, z.B. ab der Feinheit E12, werden die zum Übernehmen ausgewählten Stricknadeln 4 einwandfrei mit ihren kleinen Nadelhaken 5 in die zum Übergeben vorgelegten Maschen einfädeln können, und bei eventuell geschlossenem Nadelkopf wird die zu übergebende Masche die Nadelzunge 6 der übernehmenden Stricknadel 4 sicher öffnen. Also when hanging with fine knitting needles 4, e.g. Starting from the fineness E12, the knitting needles 4 selected for taking over will be able to thread perfectly with their small needle hooks 5 into the stitches submitted for transfer, and if the needle head is closed, the stitch to be transferred will open the needle tongue 6 of the taking over knitting needle 4 safely.
