Definitions
- the invention relates to a contact rail arrangement for the warp thread monitor of a textile machine, with a cross-sectionally U-shaped metallic outer rail and a longitudinally movable inner rail which is electrically insulated from it and toothed at the upper edge.
- the inner rail only has an outer part with a narrow cross section made of insulating material to arrange the rail between their legs, and to place the metallic and toothed part of the inner rail only on top of the part made of insulating material, so that there is a vertical distance between this metallic part and the outer rail to avoid that by damp and on the outer surfaces of the Airborne dust adhering to the inner rail can form an electrically conductive connection during weaving, which could cause incorrect shutdown of the weaving machine.
- the inner rail is not guided and held in such a way that longitudinal movement and complete removal of the inner rail from the outer rail is possible for cleaning or repair purposes, but separation of the inner rail from the outer rail in the direction perpendicular to the longitudinal direction out of the slot of the outer rail is prevented.
- dirt can easily penetrate into the slot on both sides of the inner rail guided therein, so that the possibility of easy dismantling for cleaning purposes would be advantageous.
- the object underlying the invention was therefore to create a contact rail arrangement in which the outer rail and the inner rail are guided and coupled in such a way for a relative movement to one another that the inner rail easily separates completely from the outer rail leaves, but in the operating state the inner rail does not come out of the slot in the vertical direction rail can move out.
- This longitudinal guidance and coupling should be accomplished with the simplest means and, in addition, it should be prevented in a simple manner that dirt or flying dust can penetrate into the slot of the outer rail on both sides of the inner rail.
- the contact rail arrangement has the features stated in claim 1.
- This contact rail arrangement has the advantage that the parts required for the longitudinal guidance and coupling of the inner rail with the outer rail are very inexpensive to manufacture and easy to assemble.
- the recesses to be formed in the outer rail at intervals are expediently designed as oblong holes that penetrate the outer rail, each of a guide piece which is designed to match the elongated hole and is preferably made of plastic material.
- the guide piece can preferably be held by a snap connection in the outer rail, for which purpose the guide piece expediently has a projection at the lower edge in the middle and above it a through slot which enables the projection to resiliently into the slot of the cross section U -shaped outer rail can snap into place.
- FIG. 1 shows a portion of the inner rail in side view
- FIG. 2 shows a front view of the inner rail according to FIG. 1
- Fig. 4 shows a cross section only through the outer rail along the line I-I in Fig. 3, on a larger scale
- FIG. 5 shows a cross section through the outer rail and the inner rail along the line I-I in FIG. 3
- Fig. 7 is a side view of the guide piece on a larger scale compared to Fig. 3
- FIG. 8 shows a cross section through the guide piece according to line II-II in FIG. 7.
- the inner rail 1 according to FIG. 1 has a rail-shaped part 2 made of insulating material, the cross section of which is shown in FIG. 2 and on a larger scale in FIG. 6.
- the part 2 made of insulating material is wider than in its lower section 4 and the wider section tapers with inclined outer surfaces towards the upper edge, from which a groove 5 extends into the part 2 consisting of insulating material, in which a metallic rail 6 is fixedly arranged, which is provided at the upper edge with teeth 7 arranged at intervals.
- the width of the widened upper section 3 of the part 2 of the inner rail 1 made of insulating material corresponds to the outer width of the outer rail 8 with a U-shaped cross section, into the slot 9 of which the inner rail 1 extends, the wider section 3 the inner rail covers the outer rail 8 at the top, as a result of which the slot 9 in the outer rail 8 is also covered and no dirt or dust can penetrate into it.
- the part 2 of the inner rail 1, which is made of insulating material, has at the lower edge an edge section 10 which is widened in cross section and extends over the entire length of the part 2 consisting of insulating material.
- the inner rail 1 is held in a number of guide pieces 11, which, as can be seen in FIG. 3, are inserted into the outer rail 8 at longitudinal intervals from one another, in such a way that the inner rail 1 does not protrude upward out of the slot 9 of the outer rail 8 can be moved out.
- the inner rail 1 is coupled to the outer rail 8 with full longitudinal mobility of the inner rail in the outer rail.
- the guide pieces 11 are arranged in recesses, each preferably designed as an elongated hole 12, which penetrate the outer rail 8 transversely, as can be seen from the cross section of the outer rail according to FIG. 4 shown on a larger scale.
- the guide piece 11 shown on a larger scale in FIGS. 7 and 8 is preferably made of plastic material and has a longitudinal slot running longitudinally on the center from the upper edge
- the guide piece 11 completely fills the slot 12 in the outer rail 8 and is the same width as the outer rail 8.
- the guide piece 11 is held in place in the outer rail 8 by means of a snap connection in order to fasten it in the simplest possible manner and easily removable.
- the guide piece 11 has at the lower edge on the middle a projection 15 which is approximately the same width as the slot 9 in the outer rail 8.
- a slot 16 is formed in the guide piece 11 which extends transversely therethrough , due to which the lower part of the guide piece with the projection 15 is resilient in order to be able to snap the guide piece into the slot 9 of the outer rail 8 when inserted into the elongated hole 12 in the outer rail 8 with the projection 15.
- the inner rail 1 is thus coupled to the outer rail 8 via the guide piece 11, so that the inner rail cannot be moved upwards out of the outer rail, but can be moved in the longitudinal direction in the outer rail without limitation.

Description
Kontaktschienenanordnung für den Kettfadenwächter einer TextilmaschineContact rail arrangement for the warp thread monitor of a textile machine
Die Erfindung betrifft eine Kontaktschienenanordnung für den Kettfadenwächter einer Textilmaschine, mit einer im Querschnitt U-förmigen metallischen Aussenschiene und einer in dieser längsbeweglich geführten von dieser elektrisch isolierten, am oberen Rand gezahnten Innenschiene.The invention relates to a contact rail arrangement for the warp thread monitor of a textile machine, with a cross-sectionally U-shaped metallic outer rail and a longitudinally movable inner rail which is electrically insulated from it and toothed at the upper edge.
Bei einer bekannten Kontaktschienenanordnung dieser Art (Schweizer Patent 430611) ragt die Innenschiene weit in die im Querschnitt U-förmige Aussenschiene zwischen deren Schenkel hinein und ist durch Isolierplatten von diesen Schenkeln der Aussenschiene getrennt, wodurch die gesamte Kontaktschienenanordnung sehr breit ist und die Wächterlamellen einen entsprechend breiten Schlitz aufweisen müssen. Die Innenschiene lässt sich bei dieser bekannten Anordnung auch nicht aus der Aussenschiene für Reinigungsoder Reparaturarbeiten gänzlich herausnehmen, da ein die Schenkel der Aussenschiene quer durchsetzender Bolzen durch ein Langloch in der Innenschiene sich hindurcherstreckt, so dass die Innenschiene nur eine begrenzte Hin- und Herbewegung über eine der Länge des Langlochs entsprechende Strecke ausführen kann. Der in der Aussenschiene fest angeordnete Querbolzen verhindert eine gänzliche Trennung der Innenschiene von der Aussenschiene.In a known contact rail arrangement of this type (Swiss patent 430611), the inner rail extends far into the outer rail with a U-shaped cross section between its legs and is separated from these legs of the outer rail by insulating plates, as a result of which the entire contact rail arrangement is very wide and the guard slats correspond accordingly must have a wide slot. With this known arrangement, the inner rail cannot be completely removed from the outer rail for cleaning or repair work, since a bolt which penetrates the legs of the outer rail extends through an elongated hole in the inner rail, so that the inner rail only moves back and forth over a limited distance the route corresponding to the length of the elongated hole. The cross bolt fixed in the outer rail prevents a complete separation of the inner rail from the outer rail.
Um die Kontaktschienenanordnung im Querschnitt schmaler bauen zu können, ist es ferner bekannt (DE-OS 23 40714), die Innenschiene nur mit einem aus Isoliermaterial bestehenden im Querschnitt schmalen Teil in der Aussen
schiene zwischen deren Schenkeln anzuordnen, und den metallischen und gezahnten Teil der Innenschiene nur oben auf den aus Isoliermaterial bestehenden Teil aufzusetzen, damit ein vertikaler Abstand zwischen diesem metallischen Teil und der Aussenschiene vorhanden ist, um zu vermeiden, dass durch feuchten und an den Aussenflächen der Innenschiene anhaftenden Flugstaub während des Webens eine elektrisch leitende Verbindung entstehen kann, die Fehlabschaltungen der Webmaschine verursachen könnte.In order to be able to make the contact rail arrangement narrower in cross section, it is also known (DE-OS 23 40714) that the inner rail only has an outer part with a narrow cross section made of insulating material to arrange the rail between their legs, and to place the metallic and toothed part of the inner rail only on top of the part made of insulating material, so that there is a vertical distance between this metallic part and the outer rail to avoid that by damp and on the outer surfaces of the Airborne dust adhering to the inner rail can form an electrically conductive connection during weaving, which could cause incorrect shutdown of the weaving machine.
Bei dieser bekannten Kontaktschienenanordnung ist die Innenschiene jedoch nicht so geführt und gehalten, dass eine Längsbewegung und ein gänzliches Herausnehmen der Innenschiene aus der Aussenschiene für Reinigungsoder Reparaturzwecke möglich, aber eine Trennung der Innenschiene von der Aussenschiene in zur Längsrichtung senkrechter Richtung aus dem Schlitz der Aussenschiene heraus verhindert ist. Ausserdem kann in den Schlitz beidseits der darin geführten Innenschiene leicht Schmutz eindringen, so dass die Möglichkeit der leichten Zerlegbarkeit zwecks Reinigung von Vorteil wäre.In this known contact rail arrangement, however, the inner rail is not guided and held in such a way that longitudinal movement and complete removal of the inner rail from the outer rail is possible for cleaning or repair purposes, but separation of the inner rail from the outer rail in the direction perpendicular to the longitudinal direction out of the slot of the outer rail is prevented. In addition, dirt can easily penetrate into the slot on both sides of the inner rail guided therein, so that the possibility of easy dismantling for cleaning purposes would be advantageous.
Die der Erfindung zugrunde liegende Aufgabe bestand daher darin, eine Kontaktschienenanordnung zu schaffen, bei der ohne grossen herstellungstechnischen Aufwand bezüglich der Formgebung der Aussenschiene und der Innenschiene diese so für eine Relativbewegung zueinander geführt und gekuppelt sind, dass die Innenschiene sich leicht gänzlich von der Aussenschiene trennen lässt, aber im Betriebszuständ die Innenschiene sich nicht in der senkrechten Richtung aus dem Schlitz der Aussen
schiene heraus bewegen kann. Diese Längsführung und Kupplung soll mit einfachsten Mitteln bewerkstelligt werden und ausserdem soll auf einfache Weise verhindert werden, dass in den Schlitz der Aussenschiene beidseits der Innenschiene Schmutz oder Flugstaub eindringen kann. Zur Lösung dieser Aufgabe besitzt die Kontaktschienenanordnung die in Anspruch 1 angeführten Merkmale. Diese Kontaktschienenanordnung besitzt den Vorteil, dass die für die Längsführung und Kupplung der Innenschiene mit der Aussenschiene erforderlichen Teile sehr preisgünstig herzustellen und einfach zu montieren sind» Zweckmässig werden die in der Aussenschiene in Abständen auszubildenden Ausnehmungen als die Aussenschiene quer durchsetzende Langlöcher ausgebildet, die jeweils von einem zum Langloch in der Form passend ausgebildeten Führungsstück, das vorzugsweise aus Kunststoffmaterial besteht, ausgefüllt sind. Das Führungsstück kann vorzugsweise durch eine Snap-Verbindung in der Aussenschiene gehalten sein, zu welchem Zweck das Führungsstück zweckmässig am unteren Rand auf der Mitte einen Vorsprung und darüber einen Durchgangsschlitz aufweist, der es ermöglicht, dass der Vorsprung federnd in den Schlitz der im Querschnitt U-förmigen Aussenschiene einrasten kann.The object underlying the invention was therefore to create a contact rail arrangement in which the outer rail and the inner rail are guided and coupled in such a way for a relative movement to one another that the inner rail easily separates completely from the outer rail leaves, but in the operating state the inner rail does not come out of the slot in the vertical direction rail can move out. This longitudinal guidance and coupling should be accomplished with the simplest means and, in addition, it should be prevented in a simple manner that dirt or flying dust can penetrate into the slot of the outer rail on both sides of the inner rail. To achieve this object, the contact rail arrangement has the features stated in claim 1. This contact rail arrangement has the advantage that the parts required for the longitudinal guidance and coupling of the inner rail with the outer rail are very inexpensive to manufacture and easy to assemble. »The recesses to be formed in the outer rail at intervals are expediently designed as oblong holes that penetrate the outer rail, each of a guide piece which is designed to match the elongated hole and is preferably made of plastic material. The guide piece can preferably be held by a snap connection in the outer rail, for which purpose the guide piece expediently has a projection at the lower edge in the middle and above it a through slot which enables the projection to resiliently into the slot of the cross section U -shaped outer rail can snap into place.

Fig. 8 einen Querschnitt durch das Führungsstück gemäss der Linie II-II in Fig. 7.8 shows a cross section through the guide piece according to line II-II in FIG. 7.
Die Innenschiene 1 gemäss Fig. 1 weist einen aus Isoliermaterial bestehenden schienenförmigen Teil 2 auf, dessen Querschnitt aus Fig. 2 und in grösserem Massstab aus Fig. 6 hervorgeht. In seinem oberen Abschnitt 3 ist der aus Isoliermaterial bestehende Teil 2 breiter ausgebildet als in seinem unteren Abschnitt 4 und der breitere Abschnitt verjüngt sich mit schrägen Aussenflächen zum oberen Rand hin, von dem aus sich eine Nut 5 in den aus Isoliermaterial bestehenden Teil 2 hineinerstreckt, in welcher eine metallische Schiene 6 fest angeordnet ist, die am oberen Rand mit in Abständen angeordneten Zähnen 7 versehen ist.
Wie aus Fig. 5 hervorgeht, entspricht die Breite des verbreiterten oberen Abschnitts 3 des aus Isoliermaterial bestehenden Teils 2 der Innenschiene 1 der Aussenbreite der im Querschnitt U-förmigen Aussenschiene 8, in deren Schlitz 9 sich die Innenschiene 1 hineinerstreckt, wobei der breitere Abschnitt 3 der Innenschiene die Aussenschiene 8 oben abdeckt, wodurch auch der Schlitz 9 in der Aussenschiene 8 abgedeckt ist und in diesen kein Schmutz oder Flugstaub eindringen kann.The inner rail 1 according to FIG. 1 has a rail-shaped part 2 made of insulating material, the cross section of which is shown in FIG. 2 and on a larger scale in FIG. 6. In its upper section 3, the part 2 made of insulating material is wider than in its lower section 4 and the wider section tapers with inclined outer surfaces towards the upper edge, from which a groove 5 extends into the part 2 consisting of insulating material, in which a metallic rail 6 is fixedly arranged, which is provided at the upper edge with teeth 7 arranged at intervals. As can be seen from FIG. 5, the width of the widened upper section 3 of the part 2 of the inner rail 1 made of insulating material corresponds to the outer width of the outer rail 8 with a U-shaped cross section, into the slot 9 of which the inner rail 1 extends, the wider section 3 the inner rail covers the outer rail 8 at the top, as a result of which the slot 9 in the outer rail 8 is also covered and no dirt or dust can penetrate into it.
Der aus Isoliermaterial bestehende Teil 2 der Innenschiene 1 weist am unteren Rand eine im Querschnitt verbreiterte Randpartie 10 auf, die sich über die ganze Länge des aus Isoliermaterial bestehenden Teils 2 erstreckt. Mit dieser verbreiterten Randpartie 10 ist die Innenschiene 1 in einer Anzahl von Führungsstücken 11, die, wie aus Fig. 3 hervorgeht, in Längsabständen voneinander in die Aussenschiene 8 eingesetzt sind, derart gehalten,, dass die Innenschiene 1 sich nicht nach oben aus dem Schlitz 9 der Aussenschiene 8 herausbewegen lässt. Durch die Führungsstücke 1t ist die Innenschiene 1 mit der Aussenschiene 8 gekuppelt bei voller Längsbeweglichkeit der Innenschiene in der Aussenschiene.The part 2 of the inner rail 1, which is made of insulating material, has at the lower edge an edge section 10 which is widened in cross section and extends over the entire length of the part 2 consisting of insulating material. With this widened edge portion 10, the inner rail 1 is held in a number of guide pieces 11, which, as can be seen in FIG. 3, are inserted into the outer rail 8 at longitudinal intervals from one another, in such a way that the inner rail 1 does not protrude upward out of the slot 9 of the outer rail 8 can be moved out. Through the guide pieces 1t, the inner rail 1 is coupled to the outer rail 8 with full longitudinal mobility of the inner rail in the outer rail.
Die Führungsstücke 11 sind in vorzugsweise jeweils als Langloch 12 ausgebildeten Ausnehmungen angeordnet, die die Aussenschiene 8 quer durchsetzen, wie aus dem in grösserem Massstab dargestellten Querschnitt der Aussenschiene gemäss Fig. 4 hervorgeht.The guide pieces 11 are arranged in recesses, each preferably designed as an elongated hole 12, which penetrate the outer rail 8 transversely, as can be seen from the cross section of the outer rail according to FIG. 4 shown on a larger scale.
Das in grösserem Massstab in Fig. 7 und 8 dargestellte Führungsstück 11 besteht vorzugsweise aus Kunststoff
material und weist einen auf der Mitte längsverlaufenden vom oberen Rand sich hinein erstreckenden LängsschlitzThe guide piece 11 shown on a larger scale in FIGS. 7 and 8 is preferably made of plastic material and has a longitudinal slot running longitudinally on the center from the upper edge
13 auf, der im Schlitzgrund 14 erweitert ist, so dass der aus Isoliermaterial bestehende Teil 2 der Innenschiene 1 in den Längsschlitz 13 und die verbreiterte untere Randpartie 10 an dem Teil 2 in den erweiterten Schlitzgrund13, which is expanded in the slot base 14, so that the part 2 of the inner rail 1 made of insulating material into the longitudinal slot 13 and the widened lower edge portion 10 on the part 2 into the expanded slot base
14 passend eingreifen können, um die Innenschiene 1 relativ zur Aussenschiene 8 längsbeweglich zu führen, wie am besten aus Fig. 5 ersichtlich ist. Das Führungsstück 11 füllt das Langloch 12 in der Aussenschiene 8 jeweils vollständig aus und ist gleich breit wie die Aussenschiene 8.14 can engage appropriately to guide the inner rail 1 in a longitudinally movable manner relative to the outer rail 8, as can best be seen from FIG. 5. The guide piece 11 completely fills the slot 12 in the outer rail 8 and is the same width as the outer rail 8.
Das Führungsstück 11 wird mittels einer Snap-Verbindung in der Aussenschiene 8 festgehalten, um es auf möglichst einfache Weise und leicht demontierbar zu befestigen. Zu diesem Zweck weist das Führungsstück 11 am unteren Rand auf der Mitte einen Vorsprung 15 auf, der etwa gleich breit ist- wie der Schlitz 9 in der Aussenschiene 8. Oberhalb von dem Vorsprung 15 ist in dem Führungsstück 11 ein dieses quer durchsetzender Schlitz 16 ausgebildet, aufgrund dessen die untere Partie des FührungsStücks mit dem Vorsprung 15 federnd ist, um das Führungsstück beim Einsetzen in das Langloch 12 in der Aussenschiene 8 mit dem Vorsprung 15 in den Schlitz 9 der Aussenschiene 8 einschnappen lassen zu können. Damit ist die Innenschiene 1 über das Führungsstück 11 mit der Aussenschiene 8 gekuppelt, so dass sich die Innenschiene nicht aus der Aussenschiene nach oben heraus bewegen lässt, aber in Längsrichtung in der Aussenschiene ohne Begrenzung bewegbar ist.
The guide piece 11 is held in place in the outer rail 8 by means of a snap connection in order to fasten it in the simplest possible manner and easily removable. For this purpose, the guide piece 11 has at the lower edge on the middle a projection 15 which is approximately the same width as the slot 9 in the outer rail 8. Above the projection 15, a slot 16 is formed in the guide piece 11 which extends transversely therethrough , due to which the lower part of the guide piece with the projection 15 is resilient in order to be able to snap the guide piece into the slot 9 of the outer rail 8 when inserted into the elongated hole 12 in the outer rail 8 with the projection 15. The inner rail 1 is thus coupled to the outer rail 8 via the guide piece 11, so that the inner rail cannot be moved upwards out of the outer rail, but can be moved in the longitudinal direction in the outer rail without limitation.
