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-OS 110 271 (28-71f-ep) 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-OS 110 271 (28-71f-ep) 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 Fäder 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-PS 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 Pat. No. 4,137,730 it is known to clamp a group of crochet hooks in a clamping device, with spacer plates ensuring 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 the replacement of one needle. This means a considerable amount of time.

Andererseits ist es aus der US-PS 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-05 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 Pat. No. 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. Similar ches is known from the above-mentioned EP-05 Figures 8 and 9. 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 width; this finally results in webs between the grooves of 0.2 mm or less in width. 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 wird das Problem, mehr als 10 Nadeln je Zentimeter Breite einzuspannen, auf prinzipiell zwei verschiedene Weisen gelöst.In principle, the present invention solves the problem of clamping more than 10 needles per centimeter width in two different ways.

Nach Anspruch 1 werden, ebenso wie nach der US-PS 4 137 730 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-PS 4 137 730 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 on 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 dem einen Hauptteil untergebracht, und es läßt sich nach Lösung der Spannteile ohne weiteres eine einzelne Nadel auswechseln.Groups of support strips and spacer plates are accommodated 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.

Eine andere Lösung desselben Problems ergibt sich aus Anspruch 4. Hiernach werden zwar ebenfalls Nuten gefräst. Diese Nuten haben aber nur eine sehr geringe Tiefe, so daß die Gefahr einer Beschädigung der zwischen den Nuten verbleibenden Stege nicht mehr besteht. Zum sicheren Einspannen der Nadelschäfte dienen einander gegenüberliegende Nuten, von denen die einen in dem einen Hauptteil, die anderen, gegenüberliegend, in dem anderen Hauptteil vorgesehen sind. Diese Nuten umgreifen nur einen geringen Teil der Höhe der Nadelschäfte, jedenfalls wesentlich weniger als die halbe Höhe eines Nadelschafts, so daß der größte Teil der Nadelschäfte außerhalb der Nuten liegt.Another solution to the same problem results from claim 4. According to this, grooves are also milled. However, these grooves have only a very small depth, so that there is no longer any risk of damage to the webs remaining between the grooves. Opposite grooves are used to securely clamp the needle shafts, one of which is provided in one main part, the other, opposite, in the other main part. These grooves encompass only a small part of the height of the needle shafts, in any case substantially less than half the height of a needle shaft, so that the majority of the needle shafts lie outside the grooves.

Werden nach Anspruch 5 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 5, the inertial mass of the clamping device is reduced, which is to be accelerated 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.

Erste AusführungsformFirst embodiment

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. Di-e 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.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.

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 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.

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.

Zweite AusführunqsformSecond embodiment

Bei der Ausführungsform nach Figur 3 und 4 hat die Klemmvorrichtung wiederum einen Unterteil 2' und einen Klemmdeckel 4'. Beide können durch hier nicht gezeigte Schraubbolzen miteinander verspannt werden. In den Unterteil sind sehr flache Nuten 40 eingefräst, zwischen denen Stege 42 von wesentlich geringerer Breite als die der Nuten verbleiben. In den Klemmdeckel 4' sind Nuten 44 gleicher Abmessungen gefräst, zwischen denen Stege 46 gleicher Breite wie im Unterteil stehen bleiben. Die Tiefe der Nuten 40 und 44 ist wesentlich kleiner als die halbe Höhe der Nadelschäfte 20, so daß die Nadelschäfte über den größten Teil ihrer Höhe freiliegen.In the embodiment according to FIGS. 3 and 4, the clamping device in turn has a lower part 2 'and a clamping cover 4'. Both can be clamped together using bolts not shown here. Very flat grooves 40 are milled into the lower part, between which webs 42 of a substantially smaller width than that of the grooves remain. Grooves 44 of the same dimensions are milled into the clamping cover 4 ', between which webs 46 of the same width remain as in the lower part. The depth of the grooves 40 and 44 is substantially less than half the height of the needle shafts 20, so that the needle shafts are exposed over most of their height.

Die Nuten werden mit einem Satzfräser eingefräst, und zwar jeweils alle Nuten für eine Gruppe von Nadeln gleichzeitig. Bei der geringen Tiefe der Nuten ist keine Beschädigung der Stege 46 zu befürchten.The grooves are milled with a set milling cutter, and all grooves for a group of needles at the same time. Given the shallow depth of the grooves, there is no risk of damaging the webs 46.

Die Breiten der Stege können die gleichen Werte haben wie sie oben für die Dicken der Distanzbleche angegeben wurden.The widths of the webs can have the same values as those given above for the thickness of the spacer plates.

Die rückwärtigen Enden 22 der Nadeln 20 stoßen wiederum an das rückwärtige Ende des Klemmdeckels 4'. Dies ermöglicht wiederum das Ausrichten jedes Nadelpakets, sowohl nach dem ersten Einlegen der Nadeln wie auch nach dem Auswechseln einzelner Nadeln.The rear ends 22 of the needles 20 in turn abut the rear end of the clamping cover 4 '. This in turn enables the alignment of each needle pack, both after the first insertion of the needles and after the replacement of individual needles.

Auch bei dieser Ausführungsform sind als Spannteile Schraubbolzen vorgesehen, die jedoch der Einfachheit halber nicht dargestellt wurden.In this embodiment, too, bolts are provided as clamping parts, which, however, have not been shown for the sake of simplicity.

Gemeinsame Merkmale beider AusführungsformenCommon features of both embodiments

Bei beiden Ausführungsformen kann man zum Auswechseln einzelner Nadeln die Schraubbolzen 6 lösen, ohne sie aber zu entfernen, dann einzelne Nadeln rückwärts herausziehen und neue einschieben, die Nadelpakete gegen die Klemmdeckel 4 bzw. 4' ausrichten und die Schraubbolzen wieder festziehen.In both embodiments, the screw bolts 6 can be loosened to replace individual needles, but without removing them, then pulling individual needles out backwards and inserting new ones, aligning the needle packs against the clamping covers 4 or 4 ′ and tightening the screw bolts again.
