Abstract

A clamping device for attaching crochet needles to the needle bar of a galloon crochet machine or Raschel loom. The clamping device consists of two body pieces, a lower piece and a clamping lid, which are fastened together by means of clamps. In one embodiment the body piece holds the needle shafts, a spacer inserted into each interval between needles, and a support piece between the shafts of a needle and a receptacle in the lower piece. This results in the formation of needle beds. In the other embodiment very shallow grooves are milled opposite one another in both body pieces. These are only a fraction of half the height of the needle shafts, leaving the major part of the needle shaft's height free after clamping.

Description

Die vorliegende Erfindung bezieht sich auf eine Einspannvorrichtung für Häkelnadeln (im folgenden auch einfach "Nadeln"genannt). Derartige Einspannvorrichtungen werden z. B. für Häkelgalonmaschinen verwendet, wie es sich aus der EP-A-11 271 (Stand der Technik gemäß Artikel 54,3 EPÜ) derselben Anmelder ergibt. Die Einspannvorrichtung kann aber auch bei Raschelmaschinen verwendet werden. In jedem Falle wird sie an der Nadelbarre einer dieser Maschinen angebracht.The present invention relates to a clamping device for crochet needles (hereinafter also simply called "needles"). Such jigs are such. B. used for crochet gallon machines, as is apparent from EP-A-11 271 (prior art under Article 54.3 EPC) of the same applicant. The jig can also be used with Raschel machines. In any case, it is attached to the needle bar of one of these machines.

Es besteht ein Bedarf, Bänder mit 10 oder mehr Fäden je Zentimeter Breite auf Häkelgalon oder Raschelmaschinen herzustellen. Besondere Bedeutung hat dies für elastische Bänder, wie sie für Unterwäsche und Sportwäsche benötigt werden.There is a need to produce ribbons with 10 or more threads per centimeter width on crochet gallon or Raschel machines. This is particularly important for elastic bands, such as those required for underwear and sportswear.

Aus der US-A-4 137 730 ist es bekannt, in einer Einspannvorrichtung eine Gruppe von Häkelnadeln einzuspannen, wobei für die gegenseitigen Abstände zwischen den Häkelnadeln Distanzbleche sorgen. Hierdurch lassen sich Nadeln zwar dicht nebeneinander einspannen. Ist es jedoch später erforderlich, eine zerbrochene Nadel auszuwechseln, so muß die ganze Nadelgruppe aufgelöst und nach dem Austausch der einen Nadel wieder erneut sorgfältig zusammengesetzt werden. Dies bedeutet einen erheblichen Zeitaufwand.From US-A-4 137 730 it is known to clamp a group of crochet hooks in a clamping device, whereby spacing plates ensure the mutual distances between the crochet hooks. As a result, needles can be clamped close together. However, if it is later necessary to replace a broken needle, the entire group of needles must be disassembled and carefully reassembled after replacing one needle. This means a considerable amount of time.

Andererseits ist es aus der US-A-3 823 581 bekannt, in den einen Hauptteil der Einspannvorrichtung dicht nebeneinander Nuten einzufräsen, von denen jede den Schaft einer Nadel aufnimmt. Ähnliches ist aus der oben genannten EP-A-110 271 Figur 8 und 9 bekannt. Die Nuten haben zumindest annähernd die Höhe der Nadelschäfte. Dem Einfräsen einer größeren Anzahl von Nuten je Zentimeter Breite eines der Hauptteile der Einspannvorrichtung sind Grenzen gesetzt. Wird die Anzahl der Nuten auf über 10 je Zentimeter Breite erhöht, so ergeben sich schließlich Stege zwischen den Nuten von 0,2 oder weniger mm Breite. Dies läßt sich auch nicht durch Verwendung dünnerer Nadeln vermeiden, denn die Nadeln müssen eine bestimmte Stabilität haben, so daß die Verwendung von Nadeln unterhalb von 0,4 mm Breite unzweckmäßig ist.On the other hand, it is known from US-A-3 823 581 to mill closely adjacent grooves in one main part of the clamping device, each of which receives the shaft of a needle. The same is known from EP-A-110 271, FIGS. 8 and 9, mentioned above. The grooves have at least approximately the height of the needle shafts. There are limits to milling a larger number of grooves per centimeter width of one of the main parts of the clamping device. If the number of grooves is increased to over 10 per centimeter in width, webs between the grooves of 0.2 mm or less in width ultimately result. This cannot be avoided by using thinner needles, because the needles must have a certain stability, so that the use of needles less than 0.4 mm wide is inappropriate.

Werden zum Einfräsen der Nuten Satzfräser verwendet, so kann man zwar eine Gruppe nebeneinanderliegender Nuten in einem Arbeitsgang herstellen. Selbst dann ist es aber technisch nicht möglich, Nuten mit dazwischen verbleibenden Stegen von 0,2 oder weniger mm herzustellen, ohne daß dabei relativ viel Ausschuß durch zerbrochene Stege entsteht.If set cutters are used to mill the grooves, a group of adjacent grooves can be made in one operation. Even then, it is not technically possible to produce grooves with webs of 0.2 mm or less remaining between them without a relatively large amount of rejects being caused by broken webs.

Durch die vorliegende Erfindung soll eine Möglichkeit geschaffen werden, mehr als 10 Nadeln je Zentimeter Breite einzuspannen.The present invention is intended to create a possibility of clamping more than 10 needles per centimeter in width.

Nach Anspruch 1 werden, ebenso wie nach der US-A-4137 730 zwischen den Nadelschäften Distanzbleche angeordnet. Es wird aber dafür gesorgt, daß jede einzelne Nadel für sich ausgetauscht werden kann. Dies wird dadurch erreicht, daß zwischen die Distanzbleche nicht nur die Nadelschäfte selbst sondern außerdem Stützstreifen eingefügt werden. Es ergibt sich somit aus Stützstreifen und Distanzblechen ein kammartiges Gebilde, in das die Schäfte der Nadeln einzeln eingelegt werden können. Da es keine Schwierigkeiten bereitet, sehr dünne Distanzbleche zu verwenden, ergibt sich die Grenze der Anzahl von Nadeln, die je Zentimeter Breite unterzubringen sind, nur noch aus der notwendigen Dicke der Nadelschäfte und den notwendigen gegenseitigen Abständen der Arbeitsbereiche der Nadeln.According to claim 1, as well as according to US-A-4137 730, spacer plates are arranged between the needle shafts. However, it is ensured that each individual needle can be replaced individually. This is achieved in that not only the needle shafts themselves but also support strips are inserted between the spacer plates. The result of the support strips and spacer sheets is a comb-like structure in which the shafts of the needles can be inserted individually. Since it is not difficult to use very thin spacer plates, the limit of the number of needles that can be accommodated per centimeter width only results from the necessary thickness of the needle shafts and the necessary mutual distances between the working areas of the needles.

Es werden jeweils Gruppen von Stützstreifen und Distanzblechen in mehreren Ausnehmungen in dem einen Hauptteil untergebracht, und es läßt sich nach Lösung der Spannteile ohne weiteres eine einzelne Nadel auswechseln.Groups of support strips and spacer sheets are accommodated in several recesses in one main part, and a single needle can be easily replaced after the tensioning parts have been released.

Werden nach Anspruch 2 die Stützstreifen und die Distanzbleche miteinander verklebt, so erhöht sich die Sicherheit, daß beim Auswechseln einer Nadel nicht andere Teile verschoben werden.If, according to claim 2, the support strips and the spacer plates are glued together, the security increases that other parts are not moved when a needle is replaced.

Werden nach Anspruch 4 die Hauptteile aus Leichtmetall gefertigt, so wird die träge Masse der Einspannvorrichtung verringert, die bei der Hin- und Herbewegung der Nadelbarre ständig hin und her zu beschleunigen ist. Es kann so die Arbeitsgeschwindigkeit der Maschinen erhöht werden.If the main parts are made of light metal according to claim 4, the inertial mass of the clamping device is reduced, which is to be accelerated constantly back and forth during the back and forth movement of the needle bar. The working speed of the machines can be increased in this way.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnungen beschrieben.

  • Figur 1 ist ein Schnitt quer zur Längsrichtung der Nadeln durch eine Einspannvorrichtung nach der Erfindung nach Linie I-I in Figur 2.
  • Figur 2 ist ein Schnitt nach Linie 11-11 in Figur 1, d. h. parallel zur Längsrichtung der Nadeln.
An embodiment of the invention is described below with reference to the drawings.
  • FIG. 1 is a section transverse to the longitudinal direction of the needles through a clamping device according to the invention along line II in FIG. 2.
  • Figure 2 is a section along line 11-11 in Figure 1, ie parallel to the longitudinal direction of the needles.

Die Einspannvorrichtung nach Figur 1 und 2 hat zwei aus Leichtmetall gefertigte Hauptteile, nämlich einen Unterteil 2 und einen Klemmdeckel 4. Als Spannteile, die zum Festziehen des Klemmdeckels 4 gegen den Unterteil 2 dienen, fungieren hier Schraubbolzen 6, die durch eine zylindrische Öffnung des Klemmdeckels 4 in eine Gewindebohrung 8 des Unterteils greifen. Der Unterteil hat Ausnehmungen 10 in Form von Rinnen von rechteckigem Querschnitt. In jeder Ausnehmung ist eine Gruppe von Stützstreifen 12 untergebracht. Die äußersten stützen sich an den Seitenwandungen 14 der Ausnehmungen 10 ab. Zwischen je zwei Stützstreifen befindet sich ein Distanzblech 16. Die Stützstreifen haben eine geringere Höhe als die Distanzbleche, so daß ein kammartiges Gebilde mit Nadelbetten 18 entsteht. Die Stützstreifen 12 haben die gleiche Dicke wie die Schäfte 20 der einzuspannenden Nadeln.The clamping device according to FIGS. 1 and 2 has two main parts made of light metal, namely a lower part 2 and a clamping cover 4. The clamping parts which serve to tighten the clamping cover 4 against the lower part 2 are screw bolts 6 which pass through a cylindrical opening in the clamping cover 4 engage in a threaded hole 8 in the lower part. The lower part has recesses 10 in the form of channels of rectangular cross section. A group of support strips 12 is accommodated in each recess. The outermost are supported on the side walls 14 of the recesses 10. There is a spacer plate 16 between each two support strips. The support strips have a lower height than the spacer plates, so that a comb-like structure with needle beds 18 is created. The support strips 12 have the same thickness as the shafts 20 of the needles to be clamped.

Die Dicken der Nadelschäfte 20, der Stützstreifen 12 und der Distanzbleche 16 sowie die Breite der Ausnehmungen 10 werden so bemessen, daß eine ganze Anzahl von Stützstreifen und Nadelschäften unter Preßpassung in die Ausnehmungen hineinpaßt, wobei jeweils ganz außen an den Seitenwandungen 14 ein Nadelschaft liegt. Die Nadeln 20 haben ein gekrümmtes Ende 22 und sind so eingespannt, daß dieses Ende gegen die Rückseite des Klemmdeckels 4 stößt. Dadurch sind alle in ihrer Längsrichtung in einfachster Weise ausgerichtet. Dies ermöglicht auch das einfache Auswechseln und Ausrichten einzelner Nadeln.The thicknesses of the needle shafts 20, the support strips 12 and the spacer plates 16 and the width of the recesses 10 are dimensioned such that a whole number of support strips and needle shafts press fit into the recesses, with a needle shaft lying on the outside of the side walls 14. The needles 20 have a curved end 22 and are clamped in such a way that this end abuts the back of the clamping cover 4. As a result, all are aligned in the simplest manner in their longitudinal direction. This also makes it easy to replace and align individual needles.

Die Distanzbleche und die Stützstreifen können miteinander verklebt sein. Diese Anordnung ermöglicht es, nach dem Lösen des Klemmdeckels eine einzelne Nadel auszuwechseln, alle anderen aber unangetastet in ihrem Nadelbett 18 liegenzulassen.The spacer plates and the support strips can be glued together. This arrangement makes it possible to replace a single needle after loosening the clamping cover, but to leave all others intact in their needle bed 18.

Wie die Figuren 1 und 2 zeigen, ist die Einspannvorrichtung sehr einfach aufgebaut und kann mit geringen Kosten hergestellt werden. Teile zur Befestigung an der Nadelbarre einer Häkelgalon-oder Raschelmaschine wurden hier nicht dargestellt, sind aber an sich bekannt.As FIGS. 1 and 2 show, the clamping device is very simple and can be manufactured at low cost. Parts for attachment to the needle bar of a crochet gallon or Raschel machine have not been shown here, but are known per se.

Zwei Zahlenbeispiele sollen veranschaulichen, daß nach der Erfindung relativ viele Nadeln je Zentimeter Breite einer Ausnehmung 10 untergebracht werden können.Two numerical examples are intended to illustrate that, according to the invention, a relatively large number of needles per centimeter width of a recess 10 can be accommodated.

Die Stützstreifen und die Distanzbleche können aus weichem Eisen bestehen oder aus Stahl. Wichtig ist, daß sie über ihre Länge durchgehend gleiche Dicken behalten.The support strips and spacers can be made of soft iron or steel. It is important that they have the same thickness throughout their length.

Zum Auswechseln einzelner Nadeln kann man die Schraubbolzen 6 lösen, ohne sie aber zu entfernen, dann einzelne Nadeln rückwärts herausziehen und neue einschieben, die Nadelpakete gegen die Klemmdeckel 4 ausrichten und die Schraubbolzen wieder festziehen.To replace individual needles, you can loosen the bolts 6 without removing them, then pull out individual needles backwards and insert new ones, align the needle packs against the clamping cover 4 and tighten the bolts again.
