Definitions
- the invention relates to a guide element for a gripper transport element of a weaving machine with first guides and with second guides, which together form a positive, one-sided open receptacle for the gripper transport element.
- Gripper transport elements are gripper bars or gripper bands, which are introduced from one side of the loom forth in a shed and thereby introduce a weft.
- the gripper conveyor elements move with the gripper either to the opposite side of the shed or to the middle of the shed, where they meet on a also transported by a gripper conveyor transfer tang, which takes over the registered weft thread and holds or from the middle of the shed to the opposite side transported further.
- the gripper conveyor elements are guided within the shed by means of guide elements. These guide elements are attached to the sley and are moved with the Webladen Gay in a shed and moved back out. They penetrate the lower warp thread of a shed.
- the hook-shaped guide elements which serve to guide a gripper conveyor element designed as a gripper belt have a guide associated with the upper side of the gripper conveyor element and one of the underside of the gripper conveyor element associated guide and a side facing away from the open side guide associated with a side surface of the rapier band is.
- the lower and / or the upper guide engage in a longitudinal groove of the upper side or the lower side of the rapier band, so that the side wall of the longitudinal groove facing the open side of the guide elements is guided on a guide of the guide elements running perpendicular to the upper side and to the lower side.
- This guide and the associated guide surface of the rapier band which is intended to avoid a horizontal deflection of the rapier band in the direction of the open side of the guide elements and thus to the reed, is relatively small. This results in the guide elements and especially but also on the gripper conveyor elements in a relatively short time severe wear.
- the gripper transport element which may also be a flexible rapier band in this case, is guided on the open side of the guide elements by means of two angled portions of the guide elements against dodging in the horizontal direction.
- the top and bottom of the gripper transport element maintain a distance to the opposite regions of the guide elements.
- the gripper transporting member is provided with a passing through the open side of the guide members portion which is guided between the opposite portions of the guide elements in the vertical direction.
- the invention has for its object to provide guide elements of the type mentioned, in which effective guides are increased in the horizontal direction.
- At least one projection protrudes inwardly from the first guides associated with the underside and / or the upper side of the gripper conveying element, which at least one projection complements the second guides with at least one of its side edges.
- the size of the guides effective in the horizontal direction can be increased, so that further surfaces of the gripper transport element can be utilized as guide surfaces. This makes it possible to reduce wear and to improve the guidance of the gripper transport element. It is possible to provide relatively large guides of the guide elements and correspondingly large guide surfaces on the gripper conveyor elements and yet to keep the cross section of the gripper conveyor elements small or to reduce them compared to the previously customary sizes. A reduction in the cross-section of the gripper conveyor elements leads to a reduction in the mass to be moved, which is advantageous for high operating speeds.
- the guides form a substantially C-shaped frame.
- relatively large guides are already possible from the basic structure.
- Guide elements 10 shown which are mounted in a row behind the other on a sley, have a C-shape and are open to a not shown, also attached to the sley reed out. They serve to guide within a shed a gripper transport element 11, which is designed as a gripper bar or gripper belt.
- Fig. 1 and 2 and in 4 to 18 the guide elements are shown in their operating position, ie when they are attached to a sley and the sley is in the position in which a gripper transport element is inserted into a shed and thereby guided by the guide elements.
- the other positions they take when the sash is pivoted are not shown.
- the guide elements each have a guide 12 which is associated with the top of the gripper conveyor element 11, and a guide 13 which is associated with the underside of the gripper conveyor element 11. Between these guides 12 and 13, a guide 14 is provided on the closed side of the guide elements 10, which in the embodiment extends perpendicular to the guides 12, 13 and which is associated with a side surface of the gripper conveyor element 11. On the opposite side of the guide 14, the guides 12 and 13 go over at right angles to extending sections that form guides 15, 16, whose height corresponds to about one third of the guide 14.
- the guides 12, 13, which are associated with the top and the bottom of the gripper conveyor element 11, serve as vertical guides, which prevent a deflection of the gripper conveyor element 11 in the vertical direction.
- the guides 14 on one side and the guides 15, 16 on the other side serve as horizontal guides, which prevent deflection of the gripper conveyor element 11 in the horizontal direction.
- the guides 12, 13, 14, 15 and 16 form a receptacle which secures the gripper transport element in a form-fitting manner against deviations in the horizontal and vertical direction from the movement path and which is open on the side facing a reed, not shown.
- the total height of the guides 15, 16 is in the embodiment by a third smaller than the guide 14. This creates the risk that the gripper conveyor element 11 is exposed to the side of the guides 15, 16 an increased wear.
- the guide 13 is provided with an inwardly projecting projection 17 which engages in a longitudinal groove of the gripper conveyor element 11.
- the projection 17, which in the view Fig. 1 has a preferably rectangular shape, serves with its side edges as a complementary horizontal guide.
- the height of the projection 17 is selected so that the added height of the projection 17 and the guides 15, 16 at least approximately corresponds to the height of the guide 14.
- a gripper transport member 11 will be configured as shown in FIGS. 2 and 3 that is, that it has a widening 18 extending over the entire or a part A of its length, which remains outside of the guide elements 10.
- the sections of the guide elements on the guides 15, 16 opposite outer sides also as a guide, so that the available for the horizontal guide guides are further increased.
- the widening 18 may be a guide member which receives a gripper and is attached to the gripper transport member.
- This in Fig. 4 Guide element 40 shown serves together with a plurality of successively arranged in a row guide elements 40 for guiding a gripper transport element 41, which is designed in particular as a rapier band.
- the gripper transporting member 41 has a substantially flat, rectangular shape so as to be more flexible with respect to a horizontal axis than a vertical axis. Thereby, the gripper transporting member 41 is well suited to be wrapped around a drive wheel rotating back and forth about a horizontal axis.

Description
Die Erfindung betrifft ein Führungselement für ein Greifertransportelement einer Webmaschine mit ersten Führungen und mit zweiten Führungen, die miteinander eine formschlüssige, einseitig offene Aufnahme für das Greifertransportelement bilden.The invention relates to a guide element for a gripper transport element of a weaving machine with first guides and with second guides, which together form a positive, one-sided open receptacle for the gripper transport element.
Greifertransportelemente sind Greiferstangen oder Greiferbänder, die von einer Seite der Webmaschine her in ein Webfach eingeführt werden und dabei einen Schussfaden einbringen. Die Greifertransportelemente bewegen sich mit dem Greifer entweder bis zur gegenüberliegenden Seite des Webfaches oder bis zur Mitte des Webfaches, wo sie auf einen ebenfalls von einem Greifertransportelement transportierten Übernahmegreifer treffen, der den eingetragenen Schussfaden übernimmt und festhält oder von der Mitte des Webfaches aus zur gegenüberliegenden Seite weiter transportiert. Die Greifertransportelemente werden innerhalb des Webfaches mittels Führungselementen geführt. Diese Führungselemente sind an der Weblade befestigt und werden mit der Webladenbewegung in ein Webfach hineinbewegt und wieder hinausbewegt. Dabei durchdringen sie die untere Kettfadenschar eines Webfaches.Gripper transport elements are gripper bars or gripper bands, which are introduced from one side of the loom forth in a shed and thereby introduce a weft. The gripper conveyor elements move with the gripper either to the opposite side of the shed or to the middle of the shed, where they meet on a also transported by a gripper conveyor transfer tang, which takes over the registered weft thread and holds or from the middle of the shed to the opposite side transported further. The gripper conveyor elements are guided within the shed by means of guide elements. These guide elements are attached to the sley and are moved with the Webladenbewegung in a shed and moved back out. They penetrate the lower warp thread of a shed.

Der Erfindung liegt die Aufgabe zugrunde, Führungselemente der eingangs genannten Art zu schaffen, bei denen in horizontaler Richtung wirksame Führungen vergrößert sind.The invention has for its object to provide guide elements of the type mentioned, in which effective guides are increased in the horizontal direction.
Diese Aufgabe wird dadurch gelöst, dass von den der Unterseite und/oder der Oberseite des Greifertransportelementes zugeordneten ersten Führungen wenigstens ein Vorsprung nach innen ragt, der mit wenigstens einer seiner Seitenkanten die zweiten Führungen ergänzt.This object is achieved in that at least one projection protrudes inwardly from the first guides associated with the underside and / or the upper side of the gripper conveying element, which at least one projection complements the second guides with at least one of its side edges.
Durch einen oder mehrere derartiger Vorsprünge, die in Längsnuten des Greifertransportelementes eingreifen, lässt sich die Größe der in horizontaler Richtung wirksamen Führungen vergrößern, so dass weitere Flächen des Greifertransportelementes als Führungsflächen ausgenutzt werden können. Dadurch ist es möglich, einen Verschleiß zu reduzieren und die Führung des Greifertransportelementes zu verbessern. Es ist möglich relativ große Führungen der Führungselemente und entsprechend große Führungsflächen an den Greifertransportelementen vorzusehen und dennoch den Querschnitt der Greifertransportelemente klein zu halten oder gegenüber den bisher üblichen Größen zu verkleinern. Eine Verringerung des Querschnitts der Greifertransportelemente führt zu einer Verringerung der zu bewegenden Masse, was für hohe Arbeitsgeschwindigkeiten von Vorteil ist.By one or more such projections, which engage in longitudinal grooves of the gripper transport element, the size of the guides effective in the horizontal direction can be increased, so that further surfaces of the gripper transport element can be utilized as guide surfaces. This makes it possible to reduce wear and to improve the guidance of the gripper transport element. It is possible to provide relatively large guides of the guide elements and correspondingly large guide surfaces on the gripper conveyor elements and yet to keep the cross section of the gripper conveyor elements small or to reduce them compared to the previously customary sizes. A reduction in the cross-section of the gripper conveyor elements leads to a reduction in the mass to be moved, which is advantageous for high operating speeds.
In Ausgestaltung der Erfindung wird vorgesehen, dass die Führungen einen im wesentlichen C-förmigen Rahmen bilden. Damit werden schon vom Grundaufbau her relativ große Führungen ermöglicht.In an embodiment of the invention it is provided that the guides form a substantially C-shaped frame. Thus, relatively large guides are already possible from the basic structure.

Die Führungselemente besitzen jeweils eine Führung 12, die der Oberseite des Greifertransportelements 11 zugeordnet ist, und eine Führung 13, die der Unterseite des Greifertransportelements 11 zugeordnet ist. Zwischen diesen Führungen 12 und 13 ist auf der geschlossenen Seite der Führungselemente 10 eine Führung 14 vorgesehen, die bei dem Ausführungsbeispiel lotrecht zu den Führungen 12, 13 verläuft und die einer Seitenfläche des Greifertransportelements 11 zugeordnet ist. Auf der der Führung 14 gegenüberliegenden Seite gehen die Führungen 12 und 13 in rechtwinklig dazu verlaufende Abschnitte über, die Führungen 15, 16 bilden, deren Höhe jeweils etwa einem Drittel der Führung 14 entspricht. Die Führungen 12, 13, die der Oberseite und der Unterseite des Greifertransportelements 11 zugeordnet sind, dienen als Vertikal-Führungen, die ein Ausweichen des Greifertransportelements 11 in vertikaler Richtung verhindern. Die Führungen 14 auf der einen Seite und die Führungen 15, 16 auf der anderen Seite dienen als Horizontal-Führungen, die ein Ausweichen des Greifertransportelements 11 in horizontaler Richtung verhindern. Die Führungen 12, 13, 14, 15 und 16 bilden eine Aufnahme, die das Greifertransportelement formschlüssig gegen Abweichungen in horizontaler und vertikaler Richtung von der Bewegungsbahn sichert und die auf der einem nicht dargestellten Webblatt zugewandten Seite offen ist. Die Gesamthöhe der Führungen 15, 16 ist bei dem Ausführungsbeispiel um ein Drittel kleiner als die Führung 14. Dadurch besteht die Gefahr, dass das Greifertransportelement 11 auf der Seite der Führungen 15, 16 einem erhöhten Verschleiß ausgesetzt ist. Um die ein Ausweichen in Richtung zu der offenen Seite der Führungselemente verhindernde Führung zu verbessern und die Gesamthöhe über die in dieser Richtung wirksamen Führungen 15, 16 hinaus zu erhöhen, ist bei dem Ausführungsbeispiel die Führung 13 mit einem nach innen ragenden Vorsprung 17 versehen, der in eine Längsnut des Greifertransportelements 11 eingreift.
