Abstract

The invention concerns a sinker assembly in which the sinker (1) is designed to hold modules each with a body (21; 31; 38) having two parallel faces and carrying a number of tufting, knitting or Raschel tools. The invention calls for a plane covering surface (3) in the sinker (1) and a plane stop surface (5) running perpendicular to it to define a space extending along the entire length of the sinker (1). Bolted to the sinker (1) is a clamping strip (8) whose inside surface (9) is parallel to the stop surface (5). Located in the clamping strip (8) are openings through which bolts can be passed. Running along the entire length of the stop surface (5) is a guide groove (6). Each module body (21; 31; 38) is clamped to an adapter (13) at least on the side facing the stop surface (5). The width of the assembly comprising the module body (21; 31; 38), the adapter (13) and an optional thrust pad (15) is matched to the distance between the stop surface (5) and the inside surface (9) of the clamping strip (8). Each bolt (11) has a dog point (26) which engages in and is guided by the guide groove (6). The head of each bolt (11) is countersunk in a bore in the module body (21; 31; 38) or thrust pad (15). The sinker proposed facilitates the equipping or retrofitting of such assemblies and simplifies the replacement of defective tools.

Description

Die Erfindung betrifft eine Barrenanordnung mit einer Barre zur Halterung von aus Modulkörper und darin gehaltenen Werkzeugen bestehenden Gauge Parts (Modulen) von Tufting- und Wirkmaschinen mit einem über die gesamte Länge der Barre verlaufenden Aufnahmeraum.The invention relates to a bar arrangement with a bar for holding gauge parts (modules) of tufting and knitting machines consisting of module bodies and tools held therein, with a receiving space extending over the entire length of the bar.

Es ist bekannt, eine Reihe von Tufting-, Strick- oder Raschelwerkzeugen, z.B. Nadeln oder Greifer, zunächst genau plaziert in einem Modulkörper anzuordnen und anschließend die aus den Werkzeugen und dem Modul körper bestehenden Module an einer Barre, z.B. einer Nadelbarre einer Tuftingmaschine, zu fixieren.It is known to use a number of tufting, knitting or rustling tools, e.g. Needles or grippers, first placed precisely in a module body and then the modules consisting of the tools and the module body on a bar, e.g. a needle bar of a tufting machine.

Das US-Patent 44 83 261 zeigt z.B. eine solche Barre, bei der die Module in einem über die gesamte Länge der Barre verlaufenden Aufnahmeraum eintauchen.U.S. Patent 44 83 261 shows e.g. such a bar, in which the modules are immersed in a receiving space extending over the entire length of the bar.

Eine solche Barre hat zumeist eine Länge von mehreren Metern und erfordert das Anbringen und gegebenenfalls Auswechseln einer großen Anzahl der vorbeschriebenen Module. Folglich wird für das Aus- oder Umrüsten einer solchen Barre viel Zeit benötigt.Such a bar usually has a length of several meters and requires the attachment and, if necessary, replacement of a large number of the modules described above. Consequently, it takes a lot of time to equip or convert such a bar.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Barrenanordnung zu schaffen, mit der das Aus- oder Umrüsten ohne Minderung der Präzision der Montage vereinfacht, beschleunigt und darüber hinaus ein Auswechseln einzelner Module in einfacher Weise ermöglicht wird.The object of the present invention is now to provide a bar arrangement with which the fitting or retrofitting is simplified, accelerated without reducing the precision of the assembly and, moreover, an exchange of individual modules is made possible in a simple manner.

Diese Aufgabe wird bei einer Barrenanordnung der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, daß der Aufnahmeraum in der Barre durch eine ebene Deckenfläche und eine normal dazu verlaufende ebene Anschlagfläche begrenzt ist,
daß an die Barre eine Spannleiste angeschraubt ist, deren Innenfläche parallel zur Anschlagfläche verläuft,
daß in der Spannleiste Durchstecköffnungen für Klemmschrauben vorgesehen sind, daß in der Anschlagefläche der Barre eine über ihre gesamte Länge verlaufende Führungsnut vorgesehen ist, daß mittels mindestens einer Klemmschraube jederThis object is achieved according to the invention in a bar arrangement of the type mentioned at the outset in that the receiving space in the bar is covered by a flat ceiling surface and a normal flat stop surface is limited,
that a clamping bar is screwed to the bar, the inner surface of which runs parallel to the stop surface,
that through openings for clamping screws are provided in the tensioning bar, that a guide groove running over their entire length is provided in the stop surface of the bar, that each by means of at least one clamping screw

Modul körper mindestens auf der der Anschlagfläche zugewandten Seite an ein Paßstück angeklemmt ist, daß die Breite des Verbundes aus Modul körper, Paßstück und gegebenenfalls zusätzlichem Druckstück dem Abstand zwischen der Anschlagfläche und der Innenfläche der Spannleiste angepaßt ist, daß jede Klemmschraube einen in die Führungsnut geführt eingreifenden Führungszapfen hat und daß der Kopf jeder Klemmschraube in der Bohrung eines Modul körpers oder eines Druckstücks versenkt angeordnet ist..Module body is clamped to a fitting at least on the side facing the stop surface, that the width of the assembly of module body, fitting and possibly additional pressure piece is adapted to the distance between the stop surface and the inner surface of the clamping bar, that each clamping screw leads one into the guide groove engaging guide pin and that the head of each clamping screw is sunk in the bore of a module body or a pressure piece ..

Dabei können die Module außerhalb der Barre zunächst mit einem Paßstück und gegebenenfalls mit einem zusätzlichen Druckstück zu einem Verbund zusammengestellt werden. Diese Verbunde können dann schnell und einfach in den Zwichenraum der Barrenanordnung eingefädelt und dort durch Anziehen der Spannleiste fixiert werden. Durch Lockern der Spannleiste und Lösen der Klemmschrauben können einzelne Module für sich ausgetauscht werden, insbesondere um gebrochene Werkzeuge auszutauschen.The modules can be combined outside of the bar with a fitting piece and, if necessary, with an additional pressure piece to form a composite. These composites can then be quickly and easily threaded into the intermediate space of the bar arrangement and fixed there by tightening the tensioning bar. By loosening the clamping bar and loosening the clamping screws, individual modules can be exchanged, in particular to replace broken tools.

Die erfindungsgemäße Barrenanordung kann so ausgebildet sein, daß jeder Modul körper mittels mindestens einer Klemmschraube zwischen einem Paßstück und einem Druckstück eingeklemmt ist. Dabei ist der Kopf der Klemmschrauben nicht im Modul körper zu versenken, sondern in einem Druckstück.The bar arrangement according to the invention can be designed such that each module body is clamped between a fitting piece and a pressure piece by means of at least one clamping screw. The head of the clamping screws should not be countersunk in the module body, but in a pressure piece.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß der Modulkörper über das Paßstück hinaus aus der Barrenanordnung vorsteht und daß eine Anschlagschulter des Modul körpers an eine Maßfläche des Paßstücks definiert anschlägt. Durch das Zusammenwirken von Anschlagschulter des Modul körpers und Maßfläche des Paßstücks wird die Einstiegtiefe des Moduls und damit die der darin befindlichen Werkzeuge genau definiert.The bar arrangement according to the invention can also be designed such that the module body protrudes beyond the adapter from the bar arrangement and that a stop shoulder of the module body strikes against a dimensioned surface of the adapter. Through the interaction of the stop shoulder of the module body and the dimensional surface of the adapter, the entry depth of the module and thus that of the tools located therein is precisely defined.

Die erfindungsgemäße Barrenanordnung kann so ausgebildet sein, daß die Breite des Verbundes aus Modul körper, Paßstück und gegebenenfalls Druckstück um bis zu 1/10 mm größer ist als der minimale Abstand zwischen der Anschlagfläche und der Innenfläche der Spannleiste. Auf diese Weise wird ein sicheres Klemmen der Verbunde im Zwischenraum der Barrenanordnung sichergestellt.The bar arrangement according to the invention can be designed so that the width of the composite of module body, adapter and possibly pressure piece is up to 1/10 mm larger than the minimum distance between the stop surface and the inner surface of the clamping bar. In this way, a secure clamping of the composites in the space between the bar arrangement is ensured.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß in die Spannleiste Druckschrauben eingeschraubt sind, die jeweils gegen ein Druckstück eines Verbundes oder gegen einen Modulkörper wirksam sind. Auf diese Weise werden die Verbunde jeweils für sich durch Betätigen der Druckschrauben zuverlässig festgelegt bzw. gelöst.The bar arrangement according to the invention can also be designed such that pressure screws are screwed into the clamping bar, which are each effective against a pressure piece of a composite or against a module body. In this way, the composites are reliably fixed or released individually by actuating the pressure screws.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß die Barre ein um 180° gedrehtes L-Profil hat, wobei ein erster Schenkel dieses Profils die Deckenfläche bildet und mit der Spannleiste verschraubt ist, während der zweite Schenkel die Anschlagfläche bildet.The bar arrangement according to the invention can also be designed such that the bar has an L-profile rotated by 180 °, a first leg of this profile forming the ceiling surface and being screwed to the tensioning strip, while the second leg forms the stop surface.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß einem Paßstück mehrere Module zugeordnet sind.The bar arrangement according to the invention can also be designed such that several modules are assigned to one adapter.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß jeder Modulkörper mindestens eine Öffnung zum Durchlaß einer Klemmschraube hat.The bar arrangement according to the invention can also be designed such that each module body has at least one opening for the passage of a clamping screw.

Die erfindungsgemäße Barrenanordnung kann ferner so ausgebildet sein, daß die Öffnung im Modulkörper als an einem Ende offenes Langloch ausgebildet ist. Diese Ausbildung kann beim Auswechseln einzelner Module zweckmäßig sein.The bar arrangement according to the invention can also be designed such that the opening in the module body is designed as an elongated hole that is open at one end. This training can be useful when replacing individual modules.

Die Barrenanordnung gemäß Fig. 1 hat eine Barre 1 mit um 180° gedrehtem L-Profil. Ein erster Schenkel 2 dieses Profils hat eine Deckenfläche 3. Ein zweiter Schenkel 4 weist eine ebene Anschlagfläche 5 auf, die normal zur Deckenfläche 3 verläuft. Die Anschlagfläche 5 ist über ihre Länge mit einer durchgehenden Führungsnut 6 versehen.1 has a bar 1 with an L-profile rotated by 180 °. A first leg 2 of this profile has a top surface 3. A second leg 4 has a flat stop surface 5 which extends normal to the top surface 3. The stop surface 5 is provided with a continuous guide groove 6 over its length.

Mittels Schrauben 7 ist eine Spannleiste 8 mit dem ersten Schenkel 2 der Barre 1 verschraubt. Die Spannleiste 8 kann über die gesamte Länge der Barre 1 verlaufen oder aber in mehrere Abschnitte unterteilt sein. Sie hat eine ebene Innenfläche 9, die parallel zur Anschlagfläche 5 gerichtet ist. In der Spannleiste 8 sind Durchstecköffnungen 10 für Klemmschrauben 11 vorgesehen.A clamping bar 8 is screwed to the first leg 2 of the bar 1 by means of screws 7. The clamping bar 8 can extend over the entire length of the bar 1 or can be divided into several sections. It has a flat inner surface 9 which is directed parallel to the stop surface 5. Push-through openings 10 for clamping screws 11 are provided in the clamping strip 8.

Die Deckenfläche 3 bildet mit der Anschlagfläche 5 einen Aufnahmeraum 12, der durch die Innenfläche 9 der Spannleiste 8 zusätzlich begrenzt wird.The ceiling surface 3 forms a receiving space 12 with the stop surface 5, which is additionally limited by the inner surface 9 of the clamping bar 8.

In den Aufnahmeraum 12 befinden sich bei montierter Barrenanordnung in Längsrichtung hintereinander aufgereihte Verbunde, die im Ausführungsbeispiel jeweils ein Paßstück 13, ein Nadelmodul 14 und ein Druckstück 15 umfassen, wobei diese Elemente durch Klemmschrauben 11 zusammengehalten sind.In the receiving space 12, when the ingot arrangement is mounted, there are composites lined up in the longitudinal direction, which each comprise a fitting piece 13, a needle module 14 and a pressure piece 15 in the exemplary embodiment, these elements being held together by clamping screws 11.

Jedes Paßstück 13 hat zwei parallel zueinander verlaufende Seiten 16, 17 sowie eine äußere Maßfläche 18. Die Seite 16 des Paßstücks 13 liegt an der Anschlagfläche 5 der Barre 1 an. Das Paßstück 13 hat ferner eine Kopffläche 19, welche an der Deckenfläche 3 zur Anlage kommt. In dem Paßstück 13 ist eine Gewindebohrung 20 für eine Klemmschraube 11 vorgesehen.Each adapter 13 has two mutually parallel sides 16, 17 and an outer dimension surface 18. The side 16 of adapter 13 lies against the stop surface 5 of the bar 1. The adapter 13 also has a head surface 19 which comes to rest on the ceiling surface 3. In the fitting 13, a threaded bore 20 is provided for a clamping screw 11.

Das Nadelmodul 14 hat einen Modulkörper 21, in dem exakt ausgerichtete Nadeln 22 positioniert sind. Der Modulkörper 21 hat einen Öffnung 23, durch die eine Klemmschraube 11 hindurchgesteckt werden kann.The needle module 14 has a module body 21, in which precisely aligned needles 22 are positioned. The module body 21 has an opening 23 through which a clamping screw 11 can be inserted.

An dem Modul körper 21 ist eine Anschlagschulter 24 vorgesehen, die an der Maßfläche 18 des Paßstücks 13 zur Anlage kommt. Das Druckstück 15 hat zwei parallele Seiten, von denen die eine am Modul körper 21 und die andere an der Innenfläche 9 der Spannleiste 8 anliegt. In dem Paßstück 13 ist eine Gewindebohrung 25 für eine Klemmschraube 11 vorgesehen.On the module body 21, a stop shoulder 24 is provided, which comes to rest on the measuring surface 18 of the adapter 13. The pressure piece 15 has two parallel sides, one of which abuts on the module body 21 and the other on the inner surface 9 of the clamping bar 8. In the fitting 13, a threaded bore 25 for a clamping screw 11 is provided.

Jede Klemmschraube 11 hat an ihrem vorderen Ende einen Führungszapfen 26.Each clamping screw 11 has a guide pin 26 at its front end.

Mindestens eine Klemmschraube 11 verbindet bei diesem Ausführungsbeispiel ein Paßstück 13, ein Nadelmodul 14 und ein Druckstück 15 zu einem Verbund, dessen in Richtung der Achse der Klemmschraube 11 gemessene Breite geringfügig größer ist, als die in gleicher Richtung gemessene Länge der Deckenfläche 3. Dieser Längenunterschied liegt im Bereich von weniger als 1/10 mm.In this exemplary embodiment, at least one clamping screw 11 connects a fitting piece 13, a needle module 14 and a pressure piece 15 to form a composite whose width measured in the direction of the axis of the clamping screw 11 is slightly larger than the length of the ceiling surface 3 measured in the same direction. This difference in length is in the range of less than 1/10 mm.

Die Klemmschraube 11 hat einen Senkkopf 27, der in der Gewindebohrung 25 des Druckstücks 15 versenkt angeordnet ist.The clamping screw 11 has a countersunk head 27, which is arranged sunk in the threaded bore 25 of the pressure piece 15.

Die Verbunde werden außerhalb der Barrenanordnung zusammengestellt und dann von einem Ende der Barrenanordnung aus in den Aufnahmeraum 12 eingeschoben, wobei die Führungszapfen 26 der Verbunde in der Führungsnut 6 geführt werden. Im so eingeschobenen Zustand der Verbunde stoßen die Nadelmodule 14 unmittelbar aneinander und die Köpfe 27 der Klemmschrauben 11 liegen hinter den Durchstecköffnungen 10 der Spannleiste 8. Mittels nicht dargestellter Endstücke wird der Aufnahmeraum 12 an seinen Enden nach Einführen der Verbunde geschlossen.The composites are assembled outside the ingot arrangement and then inserted into the receiving space 12 from one end of the ingot arrangement, the guide pins 26 of the composites being guided in the guide groove 6. In the thus inserted state of the composites, the needle modules 14 abut one another directly and the heads 27 of the clamping screws 11 are located behind the push-through openings 10 of the clamping strip 8. The end of the receiving space 12 is closed after insertion of the composites by means of end pieces (not shown).

Wenn eine Nadel 22 gebrochen ist und der zugehörige Nadelmodul 14 folglich ausgewechselt werden muß, so wird durch die Durchstecköffnung 10 hindurch die zugehörige Klemmschraube 11 soweit herausgedreht, daß der Verbund gelockert und der Nadelmodul 14 entfernt und durch einen anderen ersetzt werden kann.If a needle 22 is broken and the associated needle module 14 must consequently be replaced, the associated clamping screw 11 is unscrewed through the push-through opening 10 to such an extent that the composite is loosened and the needle module 14 can be removed and replaced by another.

Das in Fig. 3 dargestellte Ausführungsbeispiel zeigt eine Barre 1 mit einer Deckenfläche 3 und einer Anschlagfläche 5. Mit der Barre 1 ist, wie zuvor beschrieben, eine Spannleiste 8 mittels Schrauben 7 verbunden. Es wird also ein Aufnahmeraum 12 gebildet.The exemplary embodiment shown in FIG. 3 shows a bar 1 with a ceiling surface 3 and a stop surface 5. As previously described, a bar 8 is connected to the bar 1 by means of screws 7. A receiving space 12 is thus formed.

In diesen Aufnahmeraum 12 sind Verbunde aus einem Paßstück 13 und einem Greifermodul 30 eingeführt, wie dies zuvor für ein Nadelmodul beschrieben wurde. Dabei wird ohne Druckstücke gearbeitet. Der Kopf der verwendeten Klemmschraube 11 ist in dem Modulkörper 31 des Greifermoduls versenkt.Composites of a fitting piece 13 and a gripper module 30 are introduced into this receiving space 12, as was previously described for a needle module. It works without pressure pieces. The head of the clamping screw 11 used is countersunk in the module body 31 of the gripper module.

Der Greifermodul 30 hat zwei Anschlagsschultern 32,33, die an einer Maßfläche 34 des Paßstücks 13 sowie an der Spannleiste 8 zur Anlage kommen. Das Einführen und Auswechseln von Modulen erfolgt im übrigen in der bereits beschriebenen Weise.The gripper module 30 has two stop shoulders 32, 33, which come to rest on a dimension surface 34 of the adapter 13 and on the clamping bar 8. Incidentally, modules are introduced and replaced in the manner already described.

Die Barrenanordnung gemäß Fig. 4 entspricht weitgehend der nach Fig. 1. Abweichend davon ist aber in der Spannleiste 8 in einer Gewindebohrung 35 zumindest für jeden Verbund eine Druckschraube 36 vorgesehen, sodaß die Klemmung für jeden Verbund separat eingestellt und gelöst werden kann. In weiterer Abweichung zur Ausführungsform nach Fig. 1 ist hier in dem Modul körper 38 eines Moduls 37 zur Aufnahme einer Klemmschraube 11 ein an einem Ende offenes Langloch 39 vorgesehen, sodaß das Entfernen oder Einführen eines Moduls 37 möglich wird, ohne die Klemmschraube 11 aus dem Modul 37 herausziehen zu müssen. Der Modul 37 hat zwei Anschlagschultern 40, so daß er in den beiden um 180° zueinander verdrehten Positionen in gleicher Weise funktionsfähig ist. So werden Drehbewegungen erspart und die Montage beschleunigt.The bar arrangement according to FIG. 4 largely corresponds to that according to FIG. 1. Deviating from this, however, a pressure screw 36 is provided in the threaded strip 35 in a threaded bore 35 at least for each assembly, so that the clamping can be set and released separately for each assembly. In a further deviation from the embodiment according to FIG. 1, an elongated hole 39 open at one end is provided in the module body 38 of a module 37 for receiving a clamping screw 11, so that the removal or insertion of a module 37 is possible without the clamping screw 11 from the Pull out module 37. The module 37 has two stop shoulders 40 so that it can function in the same way in the two positions rotated by 180 ° with respect to one another. This saves rotating movements and speeds up assembly.

Die Barrenanordnung kann mit Modulen verschiedenster Art benutzt werden. Es ist möglich, solche Module einzusetzen, die mehrreihig angeordnete Werkzeuge tragen. Ferner ist es möglich, mehrere Modulreihen aneinanderliegend zu verwenden, also mit mehrreihig angeordneten Werkzeugen (22), z. B. Tuftingnadeln, zu arbeiten.The bar arrangement can be used with various types of modules. It is possible to use modules that carry tools arranged in multiple rows. It is also possible to use several rows of modules adjacent to each other, that is, with tools (22) arranged in several rows, e.g. B. tufting needles to work.
