Description

Die Erfindung betrifft einen Siebbelag mit nebeneinander befestigten, auswechselbaren Siebelementen, die an einer tragenden Unterkonstruktion befestigt sind.The invention relates to a screen covering with interchangeable, interchangeable screen elements which are attached to a supporting substructure.

Es sind für Siebböden auswechselbare Siebelemente aus Kunststoff, insbesondere Polyurethan bekannt, die an der Unterseite nahe den Längsseiten Nuten aufweisen, um die Siebelemente mit ihren Nuten über Metallschienen zu schieben, wobei der obere Bereich jeder Metallschiene in der Nut einrastet. Sollte ein Teil des Siebbodens anstelle von Kunststoffsiebelementen mit metallenen Siebgeweben oder -gittern ständig oder vorübergehend ausgerüstet sein, so ist es bekannt, Kunststoffleisten auf die Metallschienen aufzuschrauben, so daß die Metallsiebe auf die Metallschienen aufgepreßt werden. Hierzu müssen im Metallsieb und in der Metallschiene Löcher für die Schrauben gebohrt werden. Alternativ ist es bekannt, zur Befestigung von Preßschweißgittern Kunststoffleisten an die Metallschienen einrastend zu befestigen und diese Kunststoffleisten mit waagerechten Bohrungen zu versehen, um in diesen die Enden der Preßschweißgitter einzuschieben. Beide Befestigungsarten sind zeit- und arbeitsaufwendig in der Montage und erfordern für jedes Metallsieb eine besondere Anpassung. Ein Wechsel der Metallsiebarten erfordert einen erheblichen Aufwand.Interchangeable sieve elements made of plastic, in particular polyurethane, are known for sieve trays, which have grooves on the underside near the long sides in order to push the sieve elements with their grooves over metal rails, the upper region of each metal rail engaging in the groove. Should a part of the sieve bottom be equipped with metal sieve meshes or grids permanently or temporarily instead of plastic sieve elements, it is known to screw plastic strips onto the metal rails so that the metal sieves are pressed onto the metal rails. For this, in the metal sieve and in holes for the screws are drilled in the metal rail. Alternatively, it is known to fasten plastic strips to the metal rails for fastening pressure welding grids and to provide these plastic strips with horizontal bores in order to insert the ends of the pressure welding grids therein. Both types of fastening are time-consuming and labor-intensive to assemble and require a special adjustment for each metal sieve. Changing the metal sieve types requires considerable effort.

Aufgabe der Erfindung ist es, einen Siebbelag der eingangs genannten Art derart zu verbessern, daß neben und/ oder alternativ zu Kunststoffsiebelementen Siebe aus Metall einfach und schnell zu montieren und auswechselbar sind, ohne Anpassungsarbeiten die unterschiedlichsten Metallsiebe (wie Drahtgewebe, Preßschweißgitter) befestigt und gewechselt werden können und hierbei einen sicheren Halt finden.The object of the invention is to improve a screen covering of the type mentioned in such a way that, in addition to and / or as an alternative to plastic screen elements, screens made of metal can be installed and exchanged easily and quickly, without adaptation work, the most varied of metal screens (such as wire mesh, pressure welding grid) are attached and replaced be able to find a secure hold.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf der tragenden Unterkonstruktion in dem Bereich, in dem zwei benachbarte Siebelemente aneinandergrenzen, ein Kunststoffprofil befestigt ist, das die Ränder von mindestens zwei aneinandergrenzenden Siebelementenuntergreift, daß über diesem Kunststoffprofil ein zweites, oberes Profil lösbar befestigt ist, und daß zwischen erstem und zweitem Profil zu beiden Seiten je ein Siebelement klemmend gehalten ist.This object is achieved in that a plastic profile is fastened to the load-bearing substructure in the area in which two adjacent sieve elements adjoin one another, which engages under the edges of at least two adjoining sieve elements, in that a second, upper profile is detachably fastened above this plastic profile, and that between the first and second profile a screen element is held clamped on both sides.

Diese Befestigungsweise erlaubt eine einfache und schnelle Montage der unterschiedlichsten Siebe, wobei nach dem Einsatz einer Siebart, wie z.B. einem Drahtgewebe, eine andere Siebart, wie z.B. ein Preßschweißgitter oder Kunststoffsieb,ohne Anpassungsarbeiten sicher befestigt werden kann. Ferner kann auch jederzeit bei kleinstem Arbeitsaufwand ein Kunststoffelement anstelle eines Metallsiebelements befestigt werden. Darüber hinaus bietet diese Konstruktion einen sicheren Schutz der Metallschienen vor Verschleiß, geringe Außenabmessungen und geringes Gewicht. Auch bilden das untere und obere Profil den Rand eines Siebelementes, so daß beim Auswechseln der Siebelemente nur noch die das Sieben bewirkenden Flächen und nicht die Siebelementränder erneuert werden. Dies ist eine erhebliche Materialersparnis. Die erfindungsgemäße Lehre bedeutet eine Trennung von Halteelementen und siebeffektiven Teilen eines Siebelementes.This type of fastening allows a wide variety of sieves to be installed quickly and easily, and after using a sieve, such as a wire mesh, another sieve, such as a pressure welding grid or plastic sieve, is securely fastened without adjustment work can be. Furthermore, a plastic element can be attached instead of a metal sieve element at any time with the least amount of work. In addition, this construction offers reliable protection of the metal rails against wear, small external dimensions and low weight. The lower and upper profile also form the edge of a sieve element, so that when the sieve elements are replaced, only the surfaces causing the sieving and not the edges of the sieve element are replaced. This is a considerable saving in material. The teaching according to the invention means a separation of holding elements and sieve-effective parts of a sieve element.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous embodiments of the invention are listed in the subclaims.

Drei Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 einen senkrechten Schnitt durch ein erstes Ausführungsbeispiel;
  • Fig. 2 einen senkrechten Schnitt durch ein zweites Ausführungsbeispiel;
  • Fig. 3 eine Draufsicht auf ein Siebelement nach dem zweiten Ausführungsbeispiel; und
  • Fig. 4 einen senkrechten Schnitt durch ein drittes Ausführungsbeispiel.
Three embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • Figure 1 is a vertical section through a first embodiment.
  • Figure 2 is a vertical section through a second embodiment.
  • 3 shows a plan view of a screen element according to the second exemplary embodiment; and
  • Fig. 4 is a vertical section through a third embodiment.

Die beiden Schenkel eines nach oben hin offenen U-Profils 1 bilden eine erste und zweite Metallschiene 1a, 1b, deren obere Schenkelenden nach innen umgebogen sind und zwischen sich einen Spalt 1c haben. Auf dem Profil 1 ist ein erstes, unteres Profil 2 aus Kunststoff, insbesondere Polyurethan befestigt, das an seiner Unterseite zwei Längsnuten 3, 4 aufweist, in denen die oberen Enden der Schienen 1a, 1b einrastend einliegen.The two legs of a U-profile open at the top 1 form a first and second metal rail 1a, 1b, the upper leg ends of which are bent inwards and have a gap 1c between them. A first, lower profile 2 made of plastic, in particular polyurethane, is fastened on the profile 1 and has on its underside two longitudinal grooves 3, 4, in which the upper ends of the rails 1a, 1b rest in a snap-in manner.

In der Oberseite des Profils 2 ist mittig eine Längsnut 5 eingebracht, deren beide parallelen und in der Befestigung in einer Siebmaschine meist senkrechten Seitenwände sägezahnförmige Rücksprünge 6 aufweisen, wobei die steileren Flanken dem Nutenboden zugewandt sind. In dieser Nut 5 liegt einrastend eine federförmige Leiste 7 ein, die an der Unterseite eines zweiten, oberen Profils 8 aus Kunststoff, insbesondere Polyurethan, angeformt ist. Die Leiste 7 weist dieselbe Breite wie die Nut 5 auf und besitzt komplementär geformte sägezahnförmige Erhebungen 9. Da an jeder Seitenwand oder Seitenfläche des Vorsprungs 7 und der Ausnehmung 5 zwei oder mehr,insbesondere vier bis sieben über die gesamte Leisten- bzw. auch Nutenlänge Zähne vorgesehen sind, wird nicht nur bei vollständigem Einstecken der Leiste 7 in die Nut 5 ein sicherer Halt des oberen Profils 8 geschaffen, sondern auch schon bei teilweisem Einstecken, so daß unterschiedliche Abstände der Profile 2, 8 voneinander bei sicherer Befestigung erzielbar sind. Allein bei einem Einrasten von zwei Zähnen der Leiste 7 auf jeder Seite in der Nut 5 ist ein sehr hoher Kraftaufwand in Richtung des Pfeiles A erforderlich, um das Profil 8 von dem Profil 2 zu lösen.In the top of the profile 2 there is a longitudinal groove 5 in the middle, the two parallel side walls of which are sawtooth-shaped recesses 6 which are usually vertical in the fastening in a screening machine, the steeper flanks facing the groove bottom. In this groove 5 is a spring-shaped strip 7, which is molded onto the underside of a second, upper profile 8 made of plastic, in particular polyurethane. The strip 7 has the same width as the groove 5 and has complementarily shaped sawtooth-shaped elevations 9. D a on each side wall or side surface of the projection 7 and the recess 5 two or more, in particular four to seven over the entire strip or groove length Teeth are provided, a secure hold of the upper profile 8 is created not only when the strip 7 is fully inserted into the groove 5, but also when it is partially inserted, so that different distances between the profiles 2, 8 can be achieved with secure attachment. If only two teeth of the bar 7 engage on each side in the groove 5, a very high expenditure of force in the direction of the arrow A is required in order to detach the profile 8 from the profile 2.

Zu beiden Seiten der Profile 2, 8 bilden diese zwischen sich je einen Spalt 10, 11, wobei die untere Seitenwand 1Oa, 11a der Spalten von der seitlichen Oberseite des unteren Profils 2 und die oberen Seitenwände 10b, 11b von den seitlichen Unterseiten des oberen Profils 8 gebildet werden. An den Seitenwänden 10a, 10b, 11a, 11b sind in die Spalten (Nuten) 10, 11 hineinragende, zu den Profilen 2, 8 parallele Erhebungen (Längsrippen, Lippen) 12, 13 angeformt, deren Querschnitt sich mit dem Abstand von der jeweiligen Seitenwand verjüngt und vorzugsweise zahnförmig, insbesondere sägezahnförmig ist. Die zahnförmigen Erhebungen 12 der Seitenwände 10a, 11a fluchten mit einer Flanke mit den Seitenwänden des unteren Profils 2 und sind im Querschnitt kleiner ausgeführt als die Erhebungen 13 am oberen Profil 8. Die Erhebungen 12, 13 sind aufgrund des begrenzt nachgiebigen Kunststoffmaterials flexibel.On both sides of the profiles 2, 8 they each form a gap 10, 11 between them, the lower side wall 10a, 11a of the columns are formed by the lateral top of the lower profile 2 and the upper side walls 10b, 11b by the lateral undersides of the upper profile 8. On the side walls 10a, 10b, 11a, 11b protrusions (longitudinal ribs, lips) 12, 13 protruding into the gaps (grooves) 10, 11 and parallel to the profiles 2, 8 are formed, the cross-section of which increases with the distance from the respective side wall is tapered and preferably tooth-shaped, in particular sawtooth-shaped. The tooth-shaped elevations 12 of the side walls 10a, 11a are flush with one side with the side walls of the lower profile 2 and are made smaller in cross section than the elevations 13 on the upper profile 8. The elevations 12, 13 are flexible due to the limited resilient plastic material.

In die beiden Spalte 10, 11 einliegende metallene Siebelemente, insbesondere Drahtgewebe oder Preßschweißgitter 14, 15 werden von den Seitenwänden der Spalten 10, 11, insbesondere von den Erhebungen 12, 13 erfaßt, wobei diese Erhebungen im Bereich der Siebdrähte und/oder Siebprofile begrenzt nachgeben und dabei teilweise sich nach außen hin verformen. Je nach der Stärke der Teile der metallenen Gitter ist der Vorsprung 7 des Profils 8 mehr oder weniger tief in das Profil 2 einschiebbar. Das obere Profil 8 weist insbesondere im Bereich der Erhebung 13 eine größere Breite auf als die des Unterprofils 2, so daß die Profile 1 und 2 und insbesondere die in den Spalten 10, 11 liegenden Bereiche der Siebelemente als auch die Spalte 10, 11 vor dem Siebgut sicher geschützt sind.Metal sieve elements, in particular wire mesh or pressure welding grids 14, 15, which are inserted into the two gaps 10, 11 are gripped by the side walls of the gaps 10, 11, in particular by the elevations 12, 13, these elevations yielding to a limited extent in the area of the sieve wires and / or sieve profiles and partially deform outwards. Depending on the thickness of the parts of the metal grid, the projection 7 of the profile 8 can be inserted more or less deeply into the profile 2. The upper profile 8 has, in particular in the region of the elevation 13, a greater width than that of the lower profile 2, so that the profiles 1 and 2 and in particular the regions of the sieve elements lying in the columns 10, 11 and also the columns 10, 11 in front of the Screenings are safely protected.

Das in Fig. 2 und 3 dargestellte Ausführungsbeispiel unterscheidet sich von dem nach Fig. 1 dadurch, daß statt eines metallenen Siebelements ein Siebelement 14a aus Kunststoff verwendet wird, das an den Rändern, die zwischen den Profilen 2, 8 klemmend gehalten werden, eine geringere Dicke bzw. Stärke aufweist. Diese Randstreifen 16, die zumindest an zwei einander gegenüberliegenden Seiten, insbesondere den Längsseiten angeformt sind, können mit ihrer Oberseite niedriger liegen als die siebwirksame Oberfläche des Elements, so daß eine senkrechte Seitenkante 8a des oberen Profils 8 an einer seitlichen Stirnseite des Elements 14a abdichtend anliegt. Die Randstreifen 16 weisen quer zur Längserstreckung in regelmäßigem Abstand Erhebungen bzw. Rippen 17 auf, die zusätzlich auch an den Unterseiten der Randstreifen als Erhebungen bzw. Rippen 18 angeordnet sein können und von den Erhebungen 12 und 13 erfaßt werden und damit dem Siebelement in Richtung des Randstreifens einen zusätzlichen Halt geben.The embodiment shown in FIGS. 2 and 3 differs from that according to FIG. 1 in that instead of a metal sieve element, a sieve element 14a made of plastic is used, which on the edges between the Pro filen 2, 8 are held clamped, has a smaller thickness or strength. These edge strips 16, which are integrally formed on at least two opposite sides, in particular the long sides, can lie with their upper side lower than the screen-effective surface of the element, so that a vertical side edge 8a of the upper profile 8 lies sealingly against a lateral end face of the element 14a . The edge strips 16 have transversely to the longitudinal extent at regular intervals elevations or ribs 17, which can also be arranged on the undersides of the edge strips as elevations or ribs 18 and are detected by the elevations 12 and 13 and thus the sieve element in the direction of Give the edge strip an additional hold.

Das Ausführungsbeispiel nach Fig. 4 unterscheidet sich von dem vorherigen dadurch, daß das-untere Profil 2 allein durch Zapfen 18 in Öffnungen der Unterkonstruktion, insbesondere in Bohrungen eines nicht dargestellten Profils gehalten ist.The embodiment according to FIG. 4 differs from the previous one in that the lower profile 2 is held solely by pins 18 in openings of the substructure, in particular in bores of a profile, not shown.
