Description

Die Erfindung richtet sich auf eine Vorrichtung zum Befestigen eines Nadelstreifens in einem U-förmigen Nadelträger bei nadeltragenden Textilmaschinen. Solche Textilmaschinen sind beispielsweise Streckmaschinen, Kämm-Maschinen, Hechelmaschinen, Fibrilliermaschinen, Perforiermaschinen, Breithalter und Openend-Spulen u.dgl..The invention relates to a device for fastening a pinstrip in a U-shaped needle carrier in needle-bearing textile machines. Such textile machines are, for example, stretching machines, combing machines, panting machines, fibrillation machines, perforating machines, spreader bars and open-end spools and the like.

Im Betrieb solcher Maschinen unterliegen die Nadeln außerordentlich hohen Beanspruchungen, so daß sie vielfach abbrechen und die Nadelstreifen durch neue Streifen ersetzt werden müssen. Die Nadelstreifen sind in die nutenförmigen Hohlräume der U-förmigen Nadelträger entweder eingelötet oder eingeklebt. Diese Art der Befestigung unterliegt, beispielsweise in Form von auf das Material übertragenen Schwingungen, gleichfalls erheblichen Beanspruchungen, so daß gelegentlich die Befestigung zerstört wird, was zu erheblichen Betriebsunterbrechungen führt. Die bekannte Befestigung solcher Nadelstreifen erschwert darüber hinaus das Auswechseln der Nadelstreifen, weil hierzu das Bindemittel, bevor ein neuer Nadelstreifen eingesetzt werden kann, aus den sehr schmalen Nuten vollständig entfernt werden muß.In the operation of such machines, the needles are subject to extremely high loads, so that they often break off and the pinstripes have to be replaced by new strips. The pinstripes are either soldered or glued into the groove-shaped cavities of the U-shaped needle carriers. This type of fastening is also subject to considerable stresses, for example in the form of vibrations transmitted to the material, so that the fastening is occasionally destroyed, which leads to considerable interruptions in operation. The known attachment of such pinstripes also complicates the replacement of the pinstrip because the binder must be completely removed from the very narrow grooves before a new pinstrip can be used.

Eine andere Art der Befestigung von Nadelstreifen besteht darin, diese mittels keilförmiger Klemmleisten an die eine Wand des U-förmigen Nadelträgers anzupressen. Dies erfordert eine beachtliche Baugröße, so daß eine solche Befestigung nicht bei allen Maschinen in Betracht kommen kann. Außerdem sind bei dieser Art der Fixierung zusätzliche Bauteile, wie Schrauben u.dgl. notwendig, um den Klemmleisten die erforderliche Pressung zu erteilen und sie selbst zu halten. Es werden schließlich auch an ihrem Fußende erweiterte Hohlräume der Nadelträger verwendet, in die von der Seite her der ebenfalls einen verbreiterten Fuß aufweisende Nadelstreifen eingeschoben wird. Diese Art der Befestigung erfordert bestimmte Toleranzen, was die zuverlässige Fixierung des Nadelstreifens in dem Nadelträger erschwert. Vor allem ist aber bei derartigen Maschinen selten der zum seitlichen Einschieben der Nadelstreifen erforderliche Raum vorhanden.Another type of attachment of pinstripes consists in pressing them onto the one wall of the U-shaped needle carrier by means of wedge-shaped clamping strips. This requires a considerable size, so that such attachment can not be considered in all machines. In addition, additional components such as screws and the like are in this type of fixation. necessary to give the terminal strips the required pressure and to hold them themselves. Finally, extended cavities of the needle carriers are also used at their foot end, into which the pin strip, which likewise has a widened foot, is inserted from the side. This type of attachment requires certain tolerances, which makes it difficult to reliably fix the pinstrip in the needle carrier. Above all, however, the space required for the lateral insertion of the pinstripes is rarely available in such machines.

Aufgabe der Erfindung ist eine vereinfachte Art der Befestigung von Nadelstreifen in einem Nadelträger bei nadeltragenden Textilmaschinen in einer Weise, die ohne zusätzliche Hilfselemente eine feste und den statischen Erfordernissen dieser Maschinen entsprechende mechanische Verbindung bei einem geringstmöglichen zeitlichen Aufwand herbeiführt, so daß insgesamt der Ersatz von Nadelstreifen erheblich vereinfacht werden kann. Der für den Austausch von Nadelstreifen erforderliche Kostenaufwand soll auf ein geringstmögliches Maß herabgesetzt werden.The object of the invention is a simplified method of attachment of N pinstripe in a needle carrier when the needle carrying textile machines in a way that no additional auxiliary elements fixed and the static requirements of these machines causes corresponding mechanical connection at the lowest possible expenditure of time, so that a total replacement of Pinstripes can be simplified significantly. The cost of replacing pinstripes should be reduced to a minimum.

Nach dem Grundgedanken der Erfindung sind in wenigstens einem U-Schenkel des Nadelträgers in Abstand nebeneinander mehrere parallele, von dem U-Innenraum ausgehende-und am freien Schenkelende ausmündende Nuten angeordnet, die mindestens an ihrem inneren Ende in einem spitzen Winkel zu dem U-Steg verlaufen, wobei der Nadelstreifen in einem dem Abstand der Nuten entsprechenden Abstand seitlich Nocken aufweist, die beim Einsetzen des Nadelstreifens in die Nuten eingreifen.According to the basic idea of the invention, at least one U-leg of the needle carrier is spaced apart from one another by a plurality of parallel grooves which start from the U-interior and which open out at the free leg end and which are at least at their inner end at an acute angle to the U-web extend, the pin strip laterally having cams corresponding to the distance of the grooves, which engage when the pin strip is inserted into the grooves.

Diese Nuten am Tragelement der Maschine und die Nocken am Nadelstreifen lassen sich unter einmaligem Aufwand vergleichsweise leicht herstellen. Die dadurch entstehenden Mehrkosten stehen in keinem Verhältnis zu den Einsparungen, die sich beim Gebrauch solcher Nadelstreifenbefestigungen einstellen. Diese Verbindung kann ohne zusätzliche Hilfsmittel angebracht und bei Bedarf schnell wieder gelöst werden. Ein Befestigungsmittel wie Lötzinn, Kunststoffkleber od.dgl. entfällt ebenso ersatzlos wie die bei diesen Befestigungen notwendige Erwärmung des Nadelträgers. Da die Nadelstreifen innerhalb der Maschine in Längsrichtung im allgemeinen festliegen, besteht bei Anwendung der erfindungsgemäßen Maßnahme keine Gefahr des unbeabsichtigten Lösens, da hierzu eine seitliche Verschiebung des Nadelstreifens gegenüber dem Nadelträger erforderlich wäre.These grooves on the supporting element of the machine and the cams on the pinstrip can be comparatively easily manufactured with a single effort. The resulting additional costs are disproportionate to the savings that arise when using such pinstripe fasteners. This connection can be made without additional aids and can be quickly removed if necessary. A fastener such as solder, plastic adhesive or the like. is also no longer necessary, as is the need to heat the needle carrier with these fastenings. Since the pin strips are generally fixed in the longitudinal direction within the machine, there is no risk of unintentional loosening when the measure according to the invention is used, since this would require a lateral displacement of the pin strip relative to the needle carrier.

Der einzelne Nadelstreifen läßt sich mit seinen Nocken leicht in die entsprechendenNuten des Nadelträgers einschieben, und er erhält am Ende der Nut seinen vorgesehenen festen Sitz. Die Anzahl der erforderlichen Nuten des U-förmigen Nadelträgers und Nocken des Nadelstreifens richtet sich nach den festigkeitsmäßigen Erfordernissen des Einzelfalls. Die Nocken können bei der Herstellung des Nadelstreifens im Wege des Tiefziehens angebracht werden. Es ist aber auch möglich, die Nocken stoffschlüssig an den Nadelstreifen anzuformen, wenn dieser nämlich aus einem Kunstharz-Formkörper besteht.The individual pinstrip can be easily inserted with its cams into the corresponding grooves of the needle carrier, and it receives its intended tight fit at the end of the groove. The number of grooves required for the U-shaped needle carrier and cams of the pinstrip depends on the strength requirements of the individual case . The cams can be attached by deep drawing during the manufacture of the pinstrip. However, it is also possible to integrally form the cams on the pinstrip if it consists of a synthetic resin molded body.

Die Erfindung läßt eine Reihe von Alternativen in der Gestaltung der Befestigungselemente zu. So können in ihrer weiteren Ausgestaltung die Nuten einen vom Schenkelende ausgehenden, etwa senkrecht zum U-Steg des Nadelträgers verlaufenden Abschnitt und einen daran anschließenden spitzwinklig zum U-Steg verlaufenden Endabschnitt aufweisen. Eine andere Ausführungsform sieht vor, daß sich an den senkrecht verlaufenden Abschnitt ein parallel zum U-Steg des Nadelträgers verlaufender Endabschnitt anschließt. In jedem Fall werden die Nadelstreifen mit ihren Nocken in dem quer verlaufenden Abschnitt der Nut des Nadelträgers zuverlässig gehalten.The invention allows a number of alternatives in the design of the fasteners. In their further configuration, the grooves can have a section extending from the leg end, approximately perpendicular to the U-web of the needle carrier, and an adjoining end section running at an acute angle to the U-web. Another embodiment provides that the vertical section is followed by an end section running parallel to the U-web of the needle carrier. In any case, the pin strips with their cams in the transverse ver current section of the groove of the needle carrier reliably held.

Es liegt im Bereich der Erfindung, daß der Übergang von dem etwa senkrecht verlaufenden Abschnitt in den spitzwinklig oder parallel verlaufenden Endabschnitt bogenförmig oder winkelig, vorzugsweise dann rechtwinklig, ausgebildet ist.It is within the scope of the invention that the transition from the approximately perpendicular section into the acute-angled or parallel end section is arched or angled, preferably then at right angles.

Eine andere Abwandlung der Erfindung besteht darin, daß von dem etwa senkrecht zum U-Steg verlaufenden Abschnitt der Nut mindestens zwei parallel übereinander angeordnete Endabschnitte ausgehen.Another modification of the invention is that at least two end sections arranged parallel to one another extend from the section of the groove which runs approximately perpendicular to the U-web.

Da auch bei dieser erfindungsgemäßen Art der Befestigung gewisse Toleranzen unvermeidlich sind, andererseits ein fester Sitz ohne Zuhilfenahme zusätzlicher Klemmelemente erreicht werden soll, sieht die Erfindung vor, die Tiefe der Nut in ihrem Endabschnitt zunehmend abnehmen zu lassen. Die Nut wird also zu ihrem Ende hin flacher. Damit erfährt der in der Nut geführte Nocken einen zunehmenden Anzug, der den Nadelstreifen an die gegenüberliegende Wandseite des U-förmigen Nadelträgers preßt. Der gleiche Effekt ergibt sich aber auch dann, wenn die Breite der Nut in ihrem Endabschnitt zunehmend abnimmt, so daß der in der Nut geführte Nocken des Nadelstreifens, wenn dieser in der Nut vorwärtsgeschoben wird, sich zunehmend von dem Nutgrund abhebt und damit eine seitliche Verschiebung des Nadelstreifens bewirkt.Since certain tolerances are unavoidable in this type of fastening according to the invention, on the other hand, a tight fit is to be achieved without the aid of additional clamping elements, the invention provides for the depth of the groove to decrease increasingly in its end section. The groove thus becomes flatter towards the end. The cam guided in the groove thus experiences an increasing tightening which presses the pinstripe against the opposite wall side of the U-shaped needle carrier. The same effect also arises when the width of the groove decreases increasingly in its end section, so that the cam of the needle strip guided in the groove, when it is pushed forward in the groove, increasingly lifts off the groove base and thus a lateral displacement of the pinstripe.

Erfindungsgemäß weist die Nut einen dem Nockenprofil etwa entsprechenden Querschnitt auf. Der Nockenquerschnitt und/ oder das Nockenprofil sind vorzugsweise etwa halbkreisförmig oder dreieckig ausgebildet.According to the invention, the groove has a cross section approximately corresponding to the cam profile. The cam cross section and / or the cam profile are preferably approximately semicircular or triangular.

Gemäß der Erfindung können auch an beiden Seiten des Nadelstreifens Nocken und an beiden U-Schenkeln des als Nadelträger bezeichneten Maschinenelements Nuten angeordnet sein. Diese an beiden Seiten angeordneten Nocken bzw. Nuten sind zweckmäßig gegeneinander versetzt. Die Erfindung umfaßt selbstverständlich auch die Umkehrung der Anordnung dahingehend, daß die Nocken in Maschinenelemente, d.h. dem Nadelträger, und die die Nocken aufnehmenden Nuten im Nadelstreifen angeordnet sind, ohne daß dies das Grundprinzip der Erfindung verändern würde.According to the invention, cams can also be arranged on both sides of the pinstrip and grooves can be arranged on both U-legs of the machine element referred to as the needle carrier. These cams or grooves arranged on both sides are expediently offset from one another. The invention naturally also includes the reversal of the arrangement in that the cams are arranged in machine elements, ie the needle carrier, and the cams receiving grooves in the pinstripe without this changing the basic principle of the invention.

Um die Nuten in den Innenseiten der U-Schenkel des Nadelträgers anbringen zu können, sieht die Erfindung vor, daß der Nadelträger in dem den Nuten gegenüberliegenden U-Schenkel je Nut ein Fenster aufweist. Auf diese Weise läßt sich der zum Herstellen der Nuten erforderliche Fräsvorgang auch bei engsten Raumverhältnisssen ohne weiteres durchführen. Natürlich ist auch der Zugang zum U-Hohlraum von der öffnungsseite her möglich.In order to be able to make the grooves in the inner sides of the U-legs of the needle carrier, the invention provides that the needle carrier has a window in the U-legs opposite the grooves for each groove. In this way, the milling process required to produce the grooves can be carried out easily even in the most confined spaces. Of course, access to the U-cavity from the opening side is also possible.

In der mit einer Vielzahl von Nadeln 1 besetzten Textilmaschine sind in einer der Nadelreihen entsprechenden Anzahl hier als Nadelträger-2 bezeichnete Maschinenelemente gelagert, die einen U-förmigen Querschnitt aufweisen und aus den beiden U-Schenkel 3 u. 4 sowie dem diese verbindenden U-Steg 5 bestehen. Der Hohlraum 6 des Nadelträgers 2 dient zur Aufnahme eines Nadelstreifens 7, in welchem eine bestimmte Anzahl von Nadeln 1 in einem exakt vorbestimmten Abstand voneinander fixiert sind. Ein solcher Nadelstreifen 7 kann eine sehr unterschiedliche Gestaltung aufweisen. Er ist vorgefertigt und wird in seiner Gesamtheitin den in der Textilmaschine befestigten Nadelträger 2 eingesetzt und seinerseits darin fest verankert.In the textile machine equipped with a large number of needles 1, machine elements are stored in a number corresponding to the rows of needles, here referred to as needle carrier 2, which have a U-shaped cross-section and are made from the two U-legs 3 u. 4 and the U-web 5 connecting them. The cavity 6 of the needle carrier 2 serves to receive a needle strip 7, in which a certain number of needles 1 are fixed at a precisely predetermined distance from one another. Such a pinstripe 7 can have a very different design. It is prefabricated and is inserted in its entirety into the needle carrier 2 fastened in the textile machine and in turn firmly anchored therein.

Zu diesem Zweck weist der Nadelstreifen 7 in einem Abstand x voneinander und in gleicher Höhe angeordnete Nocken 8 auf, die etwa kegelförmige Gestalt aufweisen. Ist, wie bei den Ausführungsformen nach den Fig. 7, 8, 10 u. 11, der Nadelstreifen 7 unter Verwendung einer winkelförmigen Schiene 9 oder einer U-förmigen Schiene 10 ausgebildet, so können die Nocken 8 beispielsweise durch Tiefziehen in der entsprechenden Schiene 9 bzw. 10 ausgeprägt werden. Weist hingegen der Nadelstreifen 7, wie bei der Ausführungsform nach Fig. 9, einen Kunstharz- oder Kunststoffkörper 11 auf, so sind die Nocken 8" einstückig an diesen angeformt.For this purpose, the needle strip 7 has cams 8 which are arranged at a distance x from one another and at the same height and which have an approximately conical shape. Is, as in the embodiments of FIGS. 7, 8, 10 u. 11, the pinstripe 7 is formed using an angular rail 9 or a U-shaped rail 10, the cams 8 can be shaped, for example, by deep drawing in the corresponding rail 9 or 10. If, on the other hand, the pinstripe 7, as in the embodiment according to FIG. 9, has a synthetic resin or plastic body 11, the cams 8 "are integrally formed on it.

Der U-förmige Nadelträger 2 weist in einer der Anzahl der Nocken 8 des Nadelstreifens 7 entsprechenden Zahl und einem dort verwendeten Abstand x zwischen den Nocken 8-eine Reihe von Nuten 12 auf, die in die Innenseite des Schenkels 4 des Nadelträgers 2 eingefräst sind. Diese Nuten 12 bestehen aus einem am freien Ende 13 des Schenkels 4 ausmündenden Abschnitt 14, der, mit Ausnahme der Ausführungsform nach Fig. 14, etwa senkrecht zum U-Steg 5 verläuft. An diesen Abschnitt 14 schließt sich dann über einen Bogen 15 (s.Fig.12) oder im rechten Winkel 16 oder im stumpfen Winkel 17 (s. Fig. 13) ein Endabschnitt 18 an, der bei den Ausführungsformen nach den Fig. 1 - 6 u. 12 etwa parallel zum U-Steg 5 des Nadelträgers 2 verläuft. Bei der Ausführungsform nach Fig. 13 verläuft dieser Endabschnitt im spitzen Winkel dazu.The U-shaped needle carrier 2 has, in a number corresponding to the number of cams 8 of the needle strip 7 and a distance x used there between the cams 8, a series of grooves 12 which are milled into the inside of the leg 4 of the needle carrier 2. These grooves 12 consist of a section 14 opening at the free end 13 of the leg 4, which, with the exception of the embodiment according to FIG. 14, extends approximately perpendicular to the U-web 5. This section 14 is then connected via an arch 15 (see Fig. 12) or at a right angle 16 or at an obtuse angle 17 (see FIG. 13) to an end section 18 which, in the embodiments according to FIGS. 12 runs approximately parallel to the U-web 5 of the needle carrier 2. In the embodiment according to FIG. 13, this end section extends at an acute angle to it.

Die Ausführungsform nach Fig. 14 läßt eine Lösung erkennen, bei der die gesamte Nut 12' von dem freien Ende 13 des U-Schenkels 4 aus in gerader Linie und im spitzen Winkel y zum U-Steg 5 verläuft. Der Querschnitt dieser Nuten 12 entspricht, abgesehen von bestimmten Toleranzen, demjenigen der Nocken 8 des Nadelstreifens 7.The embodiment according to FIG. 14 reveals a solution in which the entire groove 12 ′ extends from the free end 13 of the U-leg 4 in a straight line and at an acute angle y to the U-web 5. Apart from certain tolerances, the cross section of these grooves 12 corresponds to that of the cams 8 of the pinstrip 7.

Der Ausführungsform nach Fig. 8 des Nadelstreifens 7 mit jeweils zwei übereinander befindlichen Nocken 8 entspricht eine Ausführungsform des Nadelträgers 2 gemäß Fig. 13, bei der sich an den Abschnitt 14 der Nut 12 zwei schräg verlaufende, parallel übereinander angeordnete Endabschnitte 18 anschließen, die jeder einen der Nocken 8' aufnehmen.The embodiment according to FIG. 8 of the pinstrip 7, each with two cams 8 located one above the other, corresponds to an embodiment of the needle carrier 2 according to FIG. 13, in which the section 14 of the groove 12 is adjoined by two obliquely running end sections 18 arranged parallel one above the other, each of which pick up one of the cams 8 '.

Die Fig. 9 zeigt eine Ausführungsform mit schräg übereinander versetzt angeordneten Nocken 8'', die, was im einzelnen nicht wiedergegeben, aber selbstverständlich ist, eine entsprechende Nutausbildung des zugehörigen Nadelstreifens 7 verlangt. Die Fig. 5 zeigt, daß der Bogen 19 des Endabschnitts 18 der Nut 12 zum Ende hin abnehmend verläuft, d.h. die Nut zunehmend flacher wird.FIG. 9 shows an embodiment with cams 8 ″ arranged obliquely one above the other, which, which is not reproduced in detail, but is self-evident, requires a corresponding groove formation of the associated pin strip 7. Fig. 5 shows that the arc 19 of the end portion 18 of the groove 12 decreases towards the end, i.e. the groove becomes increasingly flat.

Beim Einsetzen eines Nadelstreifens 7 in den U-förmigen Nadelträger 2, wie dies in Fig. 3 angedeutet ist, werden die Nocken 8 in Übereinstimmung mit den Nuten 12 des Nadelträgers 2 gebracht und dann in die Abschnitte 14 bis zu deren Ende eingeführt und dann weiter bis in die Endabschnitte 18 verschoben, bis die Nocken 8 zum Endanschlag oder zum festen Anzug gelangen. Es genügt dann, den Hohlraum 6 des Nadelträgers 2 seitlich zu verschließen, so daß der Nadelstreifen 7 sich seitlich nicht mehr verschieben kann. Der Ausbau erfolgt in der umgekehrten Reihenfolge.When a needle strip 7 is inserted into the U-shaped needle carrier 2, as indicated in FIG. 3, the cams 8 are brought into line with the grooves 12 of the needle carrier 2 and then inserted into the sections 14 to the end thereof and then further moved into the end sections 18 until the cams 8 reach the end stop or a tight fit. It is then sufficient to close the cavity 6 of the needle carrier 2 laterally, so that the pinstripe 7 can no longer move laterally. The removal takes place in the reverse order.
