Screening machine with a screen bottom (4), which is attached to a plurality of transverse elements arranged transversely to the conveying direction of the material to be screened, every second one of which is connected to the same system of movement and the transverse elements (2) lying therebetween rest or are moved oppositely in order alternately to compress and to stretch the region of the screen bottom which is situated between two transverse elements, the gap existing between the machine side wall and the screen bottom being bridged at both lateral edges (5) of the screen bottom, said edges being situated parallel to the conveying direction, by an elongate parallel sealing body, characterized in that the sealing body is divided into individual portions (6, 7) of two different lengths, the longer portions (6) in each case extending in each position from the transverse element (2) of the one system of movement (I) to the transverse element (2) of the same system of movement (I).

Description

Die Erfindung betrifft eine Siebmaschine mit einem Siebbelag, der an mehreren quer zur Förderrichtung des Siebgutes angeordneten Querelementen befestigt ist, von denen jedes zweite an demselben Bewegungssystem angeschlossen ist und die dazwischen liegenden Querelemente ruhen oder entgegengesetzt bewegt werden, um den zwischen zwei Querelementen liegenden Bereich des Siebbelages abwechselnd zu stauchen und zu strecken, wobei an beiden seitlichen, parallel zur Förderrichtung befindlichen Rändern des Siebbelages der zwischen der Maschinenseitenwand und dem Siebbelag befindliche Spalt durch einen länglichen parallelen Dichtkörper überbrückt ist.The invention relates to a screening machine with a screen covering, which is fastened to a plurality of transverse elements arranged transversely to the conveying direction of the material to be screened, of which every second is connected to the same movement system and the intermediate elements lying therebetween rest or are moved in opposite directions around the area of the between two transverse elements Alternately compressing and stretching the screen covering, the gap between the machine side wall and the screen covering being bridged on both lateral edges of the screen covering parallel to the conveying direction by an elongated parallel sealing body.

Eine solche Seitenabdichtung ist aus der deutschen Offenlegungsschrift 28 13 630 bekannt. Bei dieser bekannten Seitenabdichtung zeigte es sich, daß die Querelemente, die sich gegenüber der Seitenabdichtung hin- und herbewegen, die aus Schaumstoff bestehende Seitenabdichtung auf der Unterseite durch ständiges Reiben verschleißen.Such a side seal is known from German Offenlegungsschrift 28 13 630. With this known side seal, it has been found that the transverse elements, which move back and forth with respect to the side seal, wear out the foam side seal on the underside by constant rubbing.

Aufgabe der Erfindung ist es, eine Siebmaschine der eingangs genannten Art derart zu verbessern, daß bei den Seitenabdichtungen ein Verschleiß aufgrund der Bewegungen der Querelemente nicht auftritt.The object of the invention is to improve a screening machine of the type mentioned in such a way that wear does not occur in the side seals due to the movements of the transverse elements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Dichtkörper in einzelne Abschnitte unterteilt ist, wobei Abschnitte sich jeweils vom Querelement des einen Bewegungssystems bis zum Querelement desselben Bewegungssystems erstrecken.This object is achieved in that the sealing body is divided into individual sections, each section extending from the cross element of the one movement system to the cross element of the same movement system.

Solche in einzelne Abschnitte unterteilte Dichtkörper können auf beiden Stirnseiten zwischen Teilen liegen, die oberhalb der Querelemente eines Bewegungssystems an diesen Querelementen befestigt sind. Hierdurch stauchen diese Querelemente abwechseld den Dichtkörper, ohne an diesem entlang zu reiben, so daß ein Verschleiß nicht entsteht. Die dazwischen liegenden Querelemente des anderen Bewegungssystems oder die ruhenden Querelemente können erst recht nicht zu einem Verschleiß führen. Darüberhinaus sind diese Dichtkörper einfach herzustellen, leicht zu montieren und erzeugen eine hohe Dichtigkeit.Such sealing bodies, which are divided into individual sections, can lie on both end faces between parts which are fastened to these transverse elements above the transverse elements of a movement system. As a result, these transverse elements alternately compress the sealing body without rubbing along it, so that there is no wear. The intervening cross elements of the other movement system or the stationary cross elements can certainly not lead to wear. In addition, these sealing bodies are easy to manufacture, easy to assemble and produce a high level of tightness.

Ein besonders sicherer Halt der Dichtkörper als auch eine einfache Befestigungsweise und geringer Verschleiß werden dann erreicht, wenn kürzere, oberhalb der Querelemente eines Bewegungssystems angeordnete Abschnitte von diesen Querelementen gehalten sind, und die dazwischen liegenden längeren .Abschnitte zumindest im oberen Bereich stirnseitig an den kürzeren anliegen. Hierbei ist es besonders vorteilhaft, wenn die kürzeren Abschnitte in nach oben hin offenen Ausnehmungen oder quer zur Förderrichtung angeordneten Profilen einliegen, die auf den Querelementen befestigt sind. Vorzugsweise wird vorgeschlagen, daß die Profile trapezförmig sind und sich nach oben hin erweitern. Auch können die kürzeren Abschnitte entsprechend trapezförmig sein.A particularly secure hold of the sealing body as well as a simple method of attachment and little wear are achieved if shorter sections arranged above the transverse elements of a movement system Sections are held by these cross elements, and the longer sections lying between them abut the shorter ones at least in the upper area. It is particularly advantageous here if the shorter sections lie in recesses which are open at the top or are arranged at right angles to the conveying direction and are fastened to the transverse elements. It is preferably proposed that the profiles be trapezoidal and widen upwards. The shorter sections can also be correspondingly trapezoidal.

Der Montage kommt es entgegen, daß die Dichtkörper nicht durch Kleben oder eine andere Befestigungsweise einzeln gehalten sein müssen. Es reicht aus, daß die längeren Abschnitte auf dem Siebbelag lose aufliegen. Vorzugsweise wird vorgeschlagen, daß die Stirnseiten der kürzeren und längeren Abschnitte abgeschrägt sind, wobei die benachbarten Stirnseiten zweier Abschnitte zueinander parallel liegen.Installation complies with the fact that the sealing bodies do not have to be held individually by gluing or another fastening method. It is sufficient for the longer sections to lie loosely on the screen covering. It is preferably proposed that the end faces of the shorter and longer sections be chamfered, the adjacent end faces of two sections being parallel to one another.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Sie zeigt perspektivisch einen Ausschnitt aus einer Siebmaschine bei abgenommener Seitenwand.An embodiment of the invention is shown in the drawing. It shows a perspective section of a screening machine with the side wall removed.

Eine nach dem Spannwellen-Prinzip arbeitende Siebmaschine weist Querelemente 1, 2 auf, die rechtwinklig zur Förderrichtung des Siebgutes liegen und von z. B. trapezförmigen Stahlprofilen gebildet werden. Jedes zweite Querelement 1 ist an einem ersten Bewegungssystem I angeschlossen und jedes zweite Querelement 2 an einem zweiten Bewegungssystem II. Hierbei können auch die Querelemente 1 stillstehen und nur die Querelemente 2 sich querOne after the expansion shafts - working principle screening machine comprises cross-members 1, 2 which are at right angles to the conveying direction of the material being screened and z. B. trapezoidal steel profiles are formed. Every second cross element 1 is connected to a first movement system I and every second cross element 2 to a second movement system II. Here, the cross elements 1 can also stand still and only the cross elements 2 can cross each other

zu ihrer Streckung hin und her entsprechend dem Pfeil 3 bewegen. Dies führt dazu, daß die Zwischenräume zwischen den Querelementen 1, 2 abwechselnd größer und kleiner werden und hierbei die an den Querelementen befestigte Siebmatte 4 aus elastischem Material abwechselnd gestaucht und gestreckt wird.to move it back and forth according to arrow 3. This leads to the spaces between the cross elements 1, 2 alternately becoming larger and smaller, and the sieve mat 4 attached to the cross elements made of elastic material being alternately compressed and stretched.

An der Oberseite der Querelemente 1, 2 und damit auf der Basis der die Querelemente bildenden Profile sind waagerechte Befestigungsleisten 9 angeschraubt oder angeschweißt, an denen wiederum Befestigungsleisten 8 angeschraubt sind, die zwischen sich die Siebmatte 4 klemmend halten.At the top of the cross members 1, 2 and thus on the basis of the profiles forming the cross members, horizontal fastening strips 9 are screwed or welded, to which in turn fastening strips 8 are screwed, which hold the sieve mat 4 between them.

Auf beiden Stirnseiten aller Querelemente ist jeweils eine in der Zeichnung nicht dargestellte Seitenwand angeordnet, wobei die Stirnseiten der Querelemente als auch die Längsseite der Siebmatte 4 nahe der Seitenwand liegen. Zwischen dem seitlichen Siebmattenrand 5 und der Seitenwand besteht stets ein Spalt, der abgedichtet werden muß. Hierzu sind oberhalb des Siebmattenrandes 5 Dichtkörper angeordnet, die aus Kunststoffschaum bestehen und bei einem rechteckigen oder quadratischen Querschnitt balkenförmig sind.A side wall (not shown in the drawing) is arranged on each of the two end faces of all the transverse elements, the end faces of the cross elements and the long side of the screen mat 4 being close to the side wall. There is always a gap between the side screen mat edge 5 and the side wall, which must be sealed. For this purpose, 5 sealing bodies are arranged above the sieve mat edge, which consist of plastic foam and are bar-shaped with a rectangular or square cross section.

Diese Dichtkörper sind in längere Abschnitte 6 und kürzere Abschnitte 7 aufgeteilt, wobei die längeren Anschnitte 6 stets eine solche Länge aufweisen, daß sie auf beiden Seiten an den Querelementen 2 desselben Bewegungssystems II enden. Somit überdecken die längeren Abschnitte 6 jeweils das Querelement 1 des Bewegungssystems I. Die kürzeren Abschnitte 7 können an der Oberseite der Querelemente 2 bzw. der Befestigungsleisten für den Siebbelag bzw. die Siebmatte befestigt sein. Hierzu ist im Ausführungsbeispiel auf der Oberseite der Befestigungsleiste 8 ein V- oder U-förmiges Profil längs des Querelements 2 befestigt, das einen entsprechend geformten kürzeren Abschnitt 7 aufnimmt. Das V- oder U-förmige Profil 10 bildet damit einen nach oben hin offenen, trapezförmigen, nach unten hin sich verjüngenden Innenraum, in dem der einen entsprechend trapezförmigen Querschnitt aufweisende Abschnitt 7 einliegt. Hierbei ist die Höhe des Abschnitts 7 größer als die des Profils 10, so daß der Abschnitt 7 das Profil 10 überragt.This sealing body 6 are divided and shorter sections 7 in longer sections, with the longer gates 6 always have such a length that it 2 of the same B ends on both sides to the cross members ewegungssystems II. Thus, the longer sections 6 each cover the cross element 1 of the movement system I. The shorter sections 7 can be fastened to the top of the cross elements 2 or the fastening strips for the screen covering or the screen mat. For this purpose, in the exemplary embodiment on the top of the Fastening strip 8 fastens a V- or U-shaped profile along the cross element 2, which receives a correspondingly shaped shorter section 7. The V-shaped or U-shaped profile 10 thus forms an upwardly open, trapezoidal, tapering downward interior, in which the section 7 having a correspondingly trapezoidal cross section lies. Here, the height of section 7 is greater than that of profile 10, so that section 7 projects beyond profile 10.

Beide Abschnitte 6 und 7 weisen die gleiche Höhe H auf und ihre waagerechten Oberseiten fluchten miteinander. Die Stirnseiten der beiden Abschnitte 6, 7 liegen zumindest im oberen Bereich aneinander.Both sections 6 and 7 have the same height H and their horizontal tops are aligned with one another. The end faces of the two sections 6, 7 lie against one another at least in the upper region.
