Description

Die vorliegende Erfindung betrifft Vorrichtungen zum Abweisen, Stauen und/oder Führen von Siebgut, die auf einem Siebbelag aus nebeneinander auf einer Unterkonstruktion befestigten Siebelementen angeordnet sind und über die Siebflächenoberseite vorstehen.The present invention relates to devices for deflecting, jamming and / or guiding screenings, which are arranged on a screen covering of sieve elements fastened next to one another on a substructure and project beyond the screen surface upper side.

Siebbeläge einer Siebmaschine weisen stets auch ungelochte Blindflächen auf. Ist die Siebfläche aus mehreren Siebelementen zusammengesetzt, so bilden die ungelochten Ränder der Siebelemente solche Blindflächen, bei denen eine Siebung nicht stattfindet. Um das Siebgut zwangsweise auf gelochte Zonen zu führen, ist es aus der DE-A-26 32 511 und aus der US-A-4,909,929 bekannt, auf der Siebfläche Abweiser zu befestigen, die aufgeklebt, angeschraubt oder angeschweißt werden. Diese Arten der Befestigung sind aufwendig und nachträglich nur schwer korrigierbar oder auswechselbar.Screen coverings of a screening machine always have unperforated blind surfaces. If the sieve surface is composed of a plurality of sieve elements, the unperforated edges of the sieve elements form such blind surfaces in which sieving does not take place. In order to force the screenings to perforated zones, it is known from DE-A-26 32 511 and from US-A-4,909,929 known to attach on the screen surface deflectors which are glued, screwed or welded. These types of attachment are complicated and subsequently difficult to correct or interchangeable.

Aufgabe der Erfindung ist es, Vorrichtungen der eingangs genannten Art so zu verbessern, dass sie bei einfacher Konstruktion leicht herstellbar, montierbar und auswechselbar sind.The object of the invention is to improve devices of the type mentioned so that they are easy to manufacture, assemble and interchangeable with a simple design.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an der Unterseite der Vorrichtung ein Befestigungselement nach unten vorsteht, das zwischen zwei Siebelementen-Stirnseiten einliegt und Mittel zur Befestigung an der Unterkonstruktion aufweist und dass das Befestigungselement ein längliches Flachprofil ist, das mit senkrechten Seitenwänden zwischen den Stirnseiten zweier Siebelemente liegt und dessen Oberseite sich parallel zur Sieboberfläche erstreckt.This object is achieved in that at the bottom of the device, a fastener projects downwards, which rests between two Siebelementen end faces and means for attachment to the substructure and that the fastener is an elongated flat profile, with vertical side walls between the end faces two sieve elements lies and whose upper side extends parallel to the sieve surface.

Aufgrund der Befestigungselemente lassen sich die Abweiser oder Stauleisten äußerst einfach zwischen den Siebelementen montieren und sind hierbei sicher gehalten. Die Befestigungselemente sind dem Siebgut nicht ausgesetzt, so dass sie nicht verschleißen.Due to the fasteners, the deflectors or barriers can be extremely easy to install between the sieve elements and are held securely. The fasteners are not exposed to the screenings, so they do not wear.

Eine besonders einfache Befestigung ist dann gegeben, wenn das Befestigungselement einen Vorsprung aufweist, mit dem es an oder in einem Tragprofil und/oder einem Zwischenprofil der Unterkonstruktion formschlüssig befestigbar ist. Hierbei kann die Befestigung des Vorsprungs am Tragprofil und/oder am Zwischenprofil eine Rastverbindung sein.A particularly simple attachment is given when the fastener has a projection with which it is positively fastened to or in a support profile and / or an intermediate profile of the substructure. Here, the attachment of the projection on the support section and / or on the intermediate profile may be a latching connection.

Auch ist von besonderem Vorteil, wenn an beiden Enden des sich längs der Sieboberfläche erstreckenden Befestigungselements jeweils ein Materialabweiser und/oder eine Stauleiste befestigt ist. Damit können an einem Befestigungselement zwei Abweiser oder Stauleisten befestigt werden.It is also of particular advantage if a material deflector and / or a batten bar is attached to both ends of the fastening element extending along the screen surface. Thus, two deflectors or barriers can be attached to a fastener.

Eine sichere und einfache Befestigung des Befestigungselements an der Unterkonstruktion wird dann erreicht, wenn das Befestigungselement mit einem Ende an einem Tragprofil und/oder Zwischenprofil und mit dem anderen Ende am anderen parallel daneben liegenden Tragprofil und/oder Zwischenprofil befestigbar ist.A secure and simple attachment of the fastener to the substructure is achieved when the fastener is fastened with one end to a support profile and / or intermediate profile and with the other end on the other parallel adjacent support profile and / or intermediate profile.

Eine alternative Befestigung mit all den oben genannten Vorteilen besteht, wenn an der Unterseite des profilförmigen Befestigungselements senkrechte Zapfen vorstehen, die in einem Längsschlitz oder in Öffnungen des Tragprofils formschlüssig, insbesondere rastend befestigbar sind. Alternativ könnnen hierzu aber auch an der Oberseite des profilförmigen Befestigungselements senkrechte Zapfen über die Sieboberfläche vorstehen, die in unterseitigen Öffnungen der Abweiser oder Stauleisten formschlüssig, insbesondere rastend befestigbar sind. Hierbei kann der obere Zapfen ein Gewinde bilden, das in ein Gewinde des Abweisers oder der Stauleiste eingreift.An alternative attachment with all the above advantages is when perpendicular to the underside of the profile-shaped fastener Projecting pins which are positively, in particular latching fastened in a longitudinal slot or in openings of the support profile. Alternatively, for this purpose, but also on the top of the profile-shaped fastener vertical pins protrude beyond the Sieboberfläche, the form-fitting, in particular latching can be fastened in the lower side openings of the deflector or Stauleisten. Here, the upper pin can form a thread which engages in a thread of the deflector or the batten bar.

Von Vorteil ist es, wenn das Befestigungselement aus Metall oder Kunststoff und der/die Abweiser oder die Stauleiste(n) aus Kunststoff, insbesondere Polyurethan sind. Hierbei kann das Polyurethan eine Härte von 60-80 vorzugsweise von 70 Shore D besitzen.It is advantageous if the fastening element made of metal or plastic and the / the deflector or the batten (s) made of plastic, in particular polyurethane. In this case, the polyurethane may have a hardness of 60-80, preferably 70 Shore D.

Der Siebbelag einer nicht dargestellten Siebmaschine ist aus mehreren Siebelementen 3 zusammengesetzt, die an einer Unterkonstruktion befestigt sind. Die Unterkonstruktion weist waagerechte Tragprofile 1 auf, die aus einem Metallhohlprofil bestehen, mit einem oberen Längsschlitz in dem Kunststoffzwischenprofile 2 rastend eingeklemmt sind, wie in Figur 2 dargestellt oder aber das Zwischenprofil 5 fehlt, wie Figur 1 zeigt.The Siebbelag a screening machine, not shown, is composed of several sieve elements 3, which are attached to a substructure. The substructure has horizontal support profiles 1, which consist of a metal hollow profile, are clamped with an upper longitudinal slot in the plastic intermediate profiles 2 latching, as shown in Figure 2 or the intermediate section 5 is missing, as Figure 1 shows.

An der Unterseite eines Abweisers 4, oder zweier Abweiser 4, oder an der Unterseite einer Stauleiste 10 ist ein Befestigungselement 6 aus Kunststoff angeformt, oder aus Metall befestigt bzw. eingeformt. Das Befestigungselement 6 ist ein längliches Flachprofil mit senkrechten Seitenwänden und einer Oberseite 6a bzw. Stirnseite die mit der Oberfläche des Siebbelages fluchtet. Hierbei ist das Befestigungselement 6 zwischen zwei Siebelementen 3 eingesetzt, und zwar vorzugsweise zwischen den Stirnseiten zweier Siebelemente an deren Kurzseiten, wie in Figur 5 dargestellt. Hierbei weist das Befestigungselement an seinen beiden Enden jeweils ein Rastprofil 5 auf um das Befestigungselement mit seinen Abweisern oder Stauleisten an dem Zwischenprofil 2 rastend, formschlüssig befestigen zu können. Dabei bildet das Rastprofil 5 einen Vorsprung 7b der einen oberen Profilbereich des Zwischenprofils 2, der im Querschnitt pilzförmig ist, untergreift.On the underside of a deflector 4, or two deflectors 4, or on the underside of a batten bar 10 is a fastening element 6 made of plastic molded, or made of metal or molded. The fastening element 6 is an elongated flat profile with vertical side walls and a top side 6a or front side which is aligned with the surface of the screen covering. In this case, the fastening element 6 is inserted between two sieve elements 3, preferably between the end faces of two sieve elements on their short sides, as shown in FIG. In this case, the fastening element at its two ends in each case a locking profile 5 to the fastener with its deflectors or staves to the intermediate profile 2 latching to be able to fix positively. In this case, the locking profile 5 forms a projection 7b of an upper profile region of the intermediate profile 2, which is mushroom-shaped in cross section, engages under.

Stattdessen kann das Rastprofil 5 aber auch einen nach unten vorragenden Vorsprung 7a besitzen der in dem oberen Längsschlitz des Tragprofils 1 einrastet, wie in Figur 1 gezeigt. In diesem Fall wird ein Kunststoffzwischenprofil 2 nicht benötigt.Instead, however, the locking profile 5 may also have a downwardly projecting projection 7a which engages in the upper longitudinal slot of the support profile 1, as shown in Figure 1. In this case, a plastic intermediate profile 2 is not needed.

Die Abweiser 7 können wie in Figur 4 dargestellt jeweils vollständig ausgeführt sein oder aber auch nur eine Hälfte 4 eines Abweisers bilden wie in Figur 3 gezeigt. In diesem Fall bilden zwei einander anliegende halbe Abweiser 4 zweier benachbarter Vorrichtungen einen kompletten Abweiser 7.As shown in FIG. 4, the deflectors 7 may each be made completely or may form only one half 4 of a deflector, as shown in FIG. In this case, two adjacent half deflector 4 of two adjacent devices form a complete deflector. 7

Ein oder zwei Stauleisten 10 können an einer oder beiden Enden eines Befestigungselementes 6 auch schräg befestigt sein, so dass sie einen Einschnürtrichter 16 bilden, wie in den Figuren 9 und 10 dargestellt.One or two stakes bars 10 may also be attached at one or both ends of a fastener 6 obliquely so that they form a constricting funnel 16, as shown in Figures 9 and 10.

In all den bisher beschriebenen Fällen ist von Bedeutung, dass das Befestigungselement 6 zwischen den Stirnseiten zweier Siebelemente formschlüssig einliegt und damit über die Sieboberseite nicht vorsteht. Die an dem Befestigungselement 6 befestigten Abweiser 4, 7 oder Stauleisten 10 überragen dagegen die Sieboberfläche bzw. die Siebelemente 3 um sich dem Siebgut entgegenzustellen. Hierbei kann die Stauleiste 10 einzelne Zinnen 11 bilden, wie in Figur 7 dargestellt.In all the cases described so far, it is important that the fastening element 6 rests positively between the end faces of two sieve elements and thus does not project beyond the sieve top side. On the other hand, the deflectors 4, 7 or barriers 10 fastened to the fastening element 6 project beyond the sieve surface or the sieve elements 3 around themselves To counter screenings. In this case, the jam bar 10 can form individual pinnacles 11, as shown in FIG.

Indem in den Figuren 11 bis 16 dargestellten Ausführungsbeispielen wird das Befestigungselement 6 von einem Kunststoffprofil 8 gebildet, das eine größere Dicke oder Breite als das Befestigungselement 6 besitzt und damit kein Flachprofil mehr ist, sondern ein Profil erheblicher Breite, wobei dieses Profil dem Zwischenprofil 2 ähnlich ist, mit dem Unterschied, dass das Kunststoffprofil 8 mit seiner Oberseite mit der Unterseite des Siebbelages bzw. der Siebelemente fluchtet. An der Unterseite des Kunststoffprofils 8 ist ein Rastprofil 2a oder sind einzelne Rastzapfen 2a angeformt die in den Längsschlitzen 1b des Tragprofils 1 einrastend befestigt sind.By the embodiments illustrated in Figures 11 to 16, the fastener 6 is formed by a plastic profile 8, which has a greater thickness or width than the fastener 6 and thus no longer flat profile, but a profile considerable width, this profile similar to the intermediate profile 2 is, with the difference that the plastic profile 8 is aligned with its upper side with the underside of the Siebbelages or the sieve elements. On the underside of the plastic profile 8 is a locking profile 2a or individual locking pins 2a are formed which are mounted in the longitudinal slots 1b of the support section 1 latching.

An der Oberseite des Kunststoffprofils 8 stehen in Abständen angeordnet bolzenförmige Vorsprünge 2b vor, die entweder mehrere Sägezahnförmige Rastprofile 14 oder ein einziges Rastprofil 15 besitzen, die in nach unten offenen Ausnehmungen der Abweiser 4 hineinragen, die entsprechend geformt sind. Damit können die Abweiser als auch nicht dargestellte Stauleisten 10 mit nach unten sich öffnende Ausnehmungen nach dem Montieren der Kunststoffprofile 8 auf die zapfenförmigen Vorsprünge 2b aufgesetzt als auch abgenommen und ausgewechselt werden.At the top of the plastic profile 8 are arranged at intervals bolt-shaped projections 2b, which either have a plurality of sawtooth-shaped locking profiles 14 or a single locking profile 15, which protrude into downwardly open recesses of the deflector 4, which are shaped accordingly. Thus, the deflector and not shown Stauleisten 10 with downwardly opening recesses after mounting the plastic profiles 8 can be placed on the peg-shaped projections 2b as well as removed and replaced.
