Description

Die Erfindung betrifft ein Siebbandsystem für ein Strandreinigungsfahrzeug mit einer flexiblen, bahnförmigen Siebbandanordnung, die über wenigstens zwei Umlenkwellen umgelenkt ist, von denen wenigstens eine angetrieben ist durch eine Antriebseinheit. Die Erfindung betrifft zudem ein Strandreinigungsfahrzeug mit einem derartigen Siebbandsystem.The invention relates to a sieve belt system for a beach cleaning vehicle with a flexible, web-shaped sieve belt arrangement which is deflected via at least two deflection shafts, at least one of which is driven by a drive unit. The invention also relates to a beach cleaning vehicle with such a sieve belt system.

Ein Strandreinigungsfahrzeug mit einem derartigen Siebbandsystem ist aus der DE 10 2010 006 278 A1 bekannt. Das Strandreinigungsfahrzeug ist ein durch einen Schlepper geschlepptes Fahrzeug. Das Strandreinigungsfahrzeug weist eine Siebbandanordnung auf, die als flexibles, flächiges Band gestaltet ist, das über zwei an gegenüberliegenden Enden des Bandes angeordnete Walzen umgelenkt ist. Die Siebbandanordnung bildet ein endlos umlaufendes Band. Die Siebbandanordnung ist angetrieben, wobei ein im Fahrbetrieb des Strandreinigungsfahrzeugs erfolgender Umlauf der Siebbandanordnung durch einen auf wenigstens eine Walze wirkenden Antrieb erzielt wird. FR 2 369 020 offenbart eine Siebvorrichtung, wobei einen endlosen, sich laufend bewegenden Vibrationsschirmriemen vorgesehen ist, durch den die mit Teilchen oder Schneidspäne auffängt und sie an die gewünschte Stelle befördert und somit den Schirm sauberhält und die Ansammlung von Schneidspänen oder Teilchen auf dem Schirm verhindert.A beach cleaning vehicle with such a sieve belt system is from the DE 10 2010 006 278 A1 known. The beach cleaning vehicle is a vehicle towed by a tugboat. The beach cleaning vehicle has a sieve belt arrangement which is designed as a flexible, flat belt which is deflected over two rollers arranged at opposite ends of the belt. The sieve belt arrangement forms an endlessly revolving belt. The sieve belt arrangement is driven, with a rotation of the sieve belt arrangement taking place when the beach cleaning vehicle is in operation by a drive acting on at least one roller. FR 2 369 020 discloses a screening device wherein an endless, continuously moving vibrating screen belt is provided through which the particles or cutting chips are caught and transported to the desired location, thus keeping the screen clean and preventing the accumulation of cutting chips or particles on the screen.

Aufgabe der Erfindung ist es, ein Siebbandsystem und ein Strandreinigungsfahrzeug der eingangs genannten Art zu schaffen, die funktionssicher gestaltet sind und eine gute und gleichbleibende Siebfunktion ermöglichen.The object of the invention is to create a sieve belt system and a beach cleaning vehicle of the type mentioned at the beginning, which are designed to be functionally reliable and enable a good and constant sieving function.

Diese Aufgabe wird für das Siebbandsystem dadurch gelöst, dass die Siebbandanordnung an gegenüberliegenden Längsseiten mit längs verlaufenden Außenriemen versehen ist, dass die Siebbandanordnung wenigstens ein Siebbandgewebe aufweist, und dass quer verlaufende Versteifungsprofile vorgesehen sind, die jeweils über eine Arbeitsbreite des wenigstens einen Siebbandgewebes erstreckt und mit dem wenigstens einen Siebbandgewebe verbunden sowie stirnendseitig an den Außenriemen befestigt sind. Dadurch ergibt sich für die Siebbandanordnung ein Verbund aus wenigstens einem Siebbandgewebe, den längs verlaufenden Außenriemen und quer verlaufenden Versteifungsprofilen. Hierdurch wird eine Längung der Siebbandanordnung vermieden, so dass auch über eine lange Betriebsdauer des Strandreinigungsfahrzeugs eine zuverlässige und funktionssichere Siebwirkung erzielt wird. Erfindungsgemäß ist der Begriff der längs verlaufenden Außenriemen und der quer verlaufenden Versteifungsprofile bezogen auf einen Umlauf der Siebbandanordnung. In Umlaufrichtung bedeutet längs verlaufend. Quer verlaufend hingegen bedeutet, dass die Versteifungsprofile entlang einer Arbeitsbreite der Siebbandanordnung und damit quer zur Umlaufrichtung erstreckt sind. Die quer verlaufenden Versteifungsprofile sind demzufolge parallel zu Drehachsen der Umlenkwellen ausgerichtet. Die Umlenkwellen können als Walzen oder auch als Antriebsradwellen ausgebildet sein, wobei in letzterem Fall mehrere Antriebsräder drehfest auf einer um die Drehachse drehenden Welle gehalten sind. Die erfindungsgemäße Lösung eignet sich sowohl für geschleppte als auch für selbstfahrende Strandreinigungsfahrzeuge.This object is achieved for the main belt system in that the main screen arrangement is provided with longitudinally running outer belts on opposite longitudinal sides, that the screen belt arrangement has at least one screen belt fabric, and that transverse reinforcement profiles are provided, each extending over a working width of the at least one screen belt fabric and with connected to the at least one screen belt fabric and attached to the outer belt at the end. This results in a composite of at least one screen belt fabric, the longitudinally extending outer belts and transverse reinforcing profiles for the screen belt arrangement. This avoids an elongation of the screen belt arrangement, so that a reliable and functionally safe screening effect is achieved even over a long period of operation of the beach cleaning vehicle. According to the invention, the term of the longitudinally extending outer belt and the transversely extending stiffening profiles is based on one revolution of the screen belt arrangement. In the direction of rotation means running longitudinally. Running transversely, on the other hand, means that the stiffening profiles extend along a working width of the sieve belt arrangement and thus transversely to the direction of rotation. The transverse stiffening profiles are therefore aligned parallel to the axes of rotation of the deflection shafts. The deflection shafts can be designed as rollers or also as drive wheel shafts, in the latter case several drive wheels in a rotationally fixed manner on a shaft rotating about the axis of rotation are held. The solution according to the invention is suitable for both towed and self-propelled beach cleaning vehicles.

In Ausgestaltung der Erfindung sind die Außenriemen im Bereich ihrer den Umlenkwellen zugewandten Innenseiten mit Profilierungen versehen, und wenigstens eine Umlenkwelle weist zwei mit komplementären Außenprofilierungen versehene Antriebsräder auf, die auf einer gemeinsamen Welle gehalten sind und formschlüssig mit den Profilierungen der Außenriemen zusammenwirken. Die Profilierungen und die komplementären Außenprofilierungen sind derart aufeinander abgestimmt, dass sich in Drehrichtung der Antriebsräder eine formschlüssige Mitnahme der Außenriemen ergibt. Erfindungsgemäß wird die Siebbandanordnung demzufolge über die beiden Außenriemen angetrieben, die schlupffrei auf den Antriebsrädern transportiert und umgelenkt werden. Die Siebbandanordnung wie auch die Außenriemen sind endlos umlaufend ausgeführt. Die Außenriemen begrenzen die Siebbandanordnung an gegenüberliegenden Längsseiten ihrer Arbeitsbreite.In an embodiment of the invention, the outer belts are provided with profiles in the area of their inner sides facing the deflection shafts, and at least one deflection shaft has two drive wheels provided with complementary outer profiles, which are held on a common shaft and interact positively with the profiles of the outer belts. The profiles and the complementary outer profiles are matched to one another in such a way that the outer belts are entrained in a form-fitting manner in the direction of rotation of the drive wheels. According to the invention, the screen belt arrangement is accordingly driven via the two outer belts, which are transported and deflected on the drive wheels without slipping. The sieve belt arrangement as well as the outer belts are designed to run endlessly. The outer belts limit the sieve belt arrangement on opposite long sides of their working width.

In weiterer Ausgestaltung der Erfindung weist die Siebbandanordnung wenigstens ein Siebbandgewebe auf, das als metallisches Tressengewebe ausgeführt ist. Das metallische Tressegewebe ist vorzugsweise aus einer Stahllegierung hergestellt. Je nach Arbeitsbreite der Siebbandanordnung ist lediglich ein einzelnes Siebbandgewebe vorgesehen oder es sind wenigstens zwei nebeneinander angeordnete Siebbandgewebe vorgesehen, wobei benachbarte Siebbandgewebe jeweils über einen Mittelriemen miteinander verbunden sind.In a further embodiment of the invention, the sieve belt arrangement has at least one sieve belt fabric which is designed as a metallic braid. The metallic braid is preferably made from a steel alloy. Depending on the working width of the screen belt arrangement, only a single screen belt fabric is provided or at least two screen belt fabrics arranged next to one another are provided, with adjacent screen belt fabrics being connected to one another via a central belt.

In weiterer Ausgestaltung der Erfindung sind die Versteifungsprofile durch Schlaufen des Tressengewebes hindurch erstreckt. Die insbesondere stabförmigen Versteifungsprofile verlaufen durch die Schlaufen des Tressengewebes hindurch, die nach Art von Augen ausgebildet sind. Hierdurch wird eine formschlüssige Verbindung zwischen den Versteifungsprofilen und dem jeweiligen Tressengewebe erzielt, ohne dass im Bereich der Schlaufen des Tressengewebes zusätzliche Befestigungsmittel zur Verankerung der Versteifungsprofile erforderlich sind. Die Außenriemen, die Versteifungsprofile und das wenigstens eine Siebbandgewebe bilden demzufolge einen stabilen Verbund. Der synchrone Antrieb der Siebbandanordnung über die Profilierungen der Außenriemen gewährleistet einen schlupffreien Transport, d. h. einen schlupffreien Umlauf der Siebbandanordnung.In a further embodiment of the invention, the stiffening profiles are extended through loops of the weave. The stiffening profiles, in particular rod-shaped, run through the loops of the braid fabric, which are designed in the manner of eyes. In this way, a form-fitting connection between the reinforcement profiles and the respective braid fabric is achieved without additional fastening means for anchoring the reinforcement profiles being required in the area of the loops of the braid fabric. The outer belts, the stiffening profiles and the at least one screen belt fabric consequently form a stable composite. The synchronous drive of the sieve belt arrangement via the profiles of the outer belts ensures slip-free transport, i.e. H. a slip-free circulation of the sieve belt arrangement.

In weiterer Ausgestaltung der Erfindung weist die Siebbandanordnung wenigstens zwei parallel nebeneinander angeordnete Siebbandgewebe auf, zwischen denen ein längs verlaufender Mittelriemen erstreckt ist, der mit den quer verlaufenden Versteifungsprofilen verbunden ist. Der Mittelriemen und die Versteifungsprofile gewährleisten, dass in einem Mittelbereich der Siebbandanordnung keine nachteilige Dehnung auftritt, die ein Durchhängen bewirken könnte.In a further embodiment of the invention, the sieve belt arrangement has at least two sieve belt fabrics arranged parallel next to one another, between which a longitudinally running central belt is extended, which is connected to the transversely running stiffening profiles. The Central belt and the stiffening profiles ensure that no disadvantageous stretching which could cause sagging occurs in a central area of the screen belt arrangement.

In weiterer Ausgestaltung der Erfindung ist jedes Siebbandgewebe auf einer von dem Mittelriemen abliegenden Außenseite mit jeweils einem Außenriemen verbunden, die parallel zu dem Mittelriemen verlaufen. Die beiden Außenriemen begrenzen demzufolge die Siebbandanordnung an gegenüberliegenden Längsseiten ihrer Arbeitsbreite.In a further embodiment of the invention, each screen belt fabric is connected to an outer side remote from the central belt, each with an outer belt which runs parallel to the central belt. The two outer belts consequently limit the screen belt arrangement on opposite longitudinal sides of their working width.

In weiterer Ausgestaltung der Erfindung sind die Versteifungsprofile an dem Mittelriemen und/oder wenigstens einem Außenriemen befestigt. Die Befestigung erfolgt vorzugsweise durch mechanische Befestigungsmittel wie insbesondere Niet- oder Schraubverbindungen. Die Versteifungsprofile sind vorzugsweise aus Stahl oder aus einem faserverstärkten Kunststoffmaterial hergestellt.In a further embodiment of the invention, the stiffening profiles are attached to the central belt and / or at least one outer belt. The fastening is preferably carried out by mechanical fastening means such as, in particular, rivet or screw connections. The stiffening profiles are preferably made of steel or a fiber-reinforced plastic material.

In weiterer Ausgestaltung der Erfindung sind der Mittelriemen und die Außenriemen im Bereich ihrer den Umlenkwellen zugewandten Innenseiten mit Profilierungen versehen, und wenigstens eine angetriebene Umlenkwelle weist drei mit komplementären Außenprofilierungen versehene Antriebsräder auf, die auf einer gemeinsamen Welle gehalten sind und mit den Profilierungen der Mittel- bzw. Außenriemen zusammenwirken. Die Antriebsräder sind drehfest auf der Welle befestigt, die um eine Drehachse drehbar gelagert ist. Die Welle bildet in Verbindung mit den Antriebsrädern eine Umlenkwelle im Sinne der Erfindung. Vorzugsweise bildet die beschriebene Umlenkwelle die Antriebswelle, die durch die Antriebseinheit beaufschlagt ist und die Siebbandanordnung bewegt.In a further embodiment of the invention, the central belt and the outer belt are provided with profiles in the area of their inner sides facing the deflection shafts, and at least one driven deflection shaft has three drive wheels provided with complementary outer profiles, which are held on a common shaft and with the profiles of the central or outer belt work together. The drive wheels are non-rotatably attached to the shaft, which is rotatably mounted about an axis of rotation. In connection with the drive wheels, the shaft forms a deflection shaft in the sense of the invention. The deflecting shaft described preferably forms the drive shaft, which is acted upon by the drive unit and moves the screen belt arrangement.

In weiterer Ausgestaltung der Erfindung sind wenigstens die Außenriemen im Bereich ihrer der Innenseite gegenüberliegenden Außenseite mit Zusatznocken versehen. Die Zusatznocken dienen zum einen als Schutz gegen schnellen Verschleiß. Zum anderen dienen sie dazu, den Transport der Siebbandanordnung im Bereich ihres Untertrums zu verbessern, indem eine verbesserte Führung im Bereich wenigstens einer Führungsrolle erzielt wird, die ebenfalls mit Nocken versehen sein kann, die mit den Zusatznocken der Außenseite der Außenriemen zusammenwirken. Im Bereich des Untertrums der Siebbandanordnung läuft die Außenseite der Außenriemen über eine Führungsrolle, so dass die Zusatznocken im Bereich der Führungsrolle mit entsprechenden Nocken der Führungsrolle zusammenwirken können.In a further embodiment of the invention, at least the outer belts are provided with additional cams in the area of their outer side opposite the inner side. On the one hand, the additional cams serve as protection against rapid wear. On the other hand, they serve to improve the transport of the sieve belt arrangement in the area of its lower strand by achieving improved guidance in the area of at least one guide roller, which can also be provided with cams which interact with the additional cams on the outside of the outer belt. In the area of the lower strand of the sieve belt arrangement, the outside of the outer belt runs over a guide roller, so that the additional cams in the area of the guide roller can interact with corresponding cams of the guide roller.

In weiterer Ausgestaltung der Erfindung sind die quer verlaufenden Versteifungsprofile über eine gesamte Breite beider Siebbandgewebe erstreckt. Damit erstrecken sich die Versteifungsprofile über die gesamte Arbeitsbreite der Siebbandanordnung.In a further embodiment of the invention, the transverse stiffening profiles extend over an entire width of both screen belt fabrics. The stiffening profiles thus extend over the entire working width of the sieve belt arrangement.

In weiterer Ausgestaltung der Erfindung sind die quer verlaufenden Versteifungsprofile über eine Breite jeweils eines Siebbandgewebes lediglich teilweise erstreckt und in Querrichtung versetzt zueinander angeordnet. Bei dieser Alternative erstrecken sich die Versteifungsprofile lediglich vollständig über die Breite jeweils eines Siebbandgewebes und ragen lediglich teilweise vom Mittelriemen aus noch in das andere Siebbandgewebe hinein. Durch die versetzte Anordnung erstrecken sich in Längsrichtung benachbarte Versteifungsprofile alternierend jeweils entweder über die linke Hälfte der Siebbandanordnung oder über die rechte Hälfte der Siebbandanordnung. Dadurch ist es möglich, unterschiedliche Teilungen der Arbeitsbreite zu erzielen und insbesondere auch parallel nebeneinander angeordnete Siebbandgewebe mit unterschiedlicher Breite zu kombinieren.In a further embodiment of the invention, the transversely extending stiffening profiles are only partially extended over the width of a respective screen belt fabric and are arranged offset to one another in the transverse direction. In this alternative, the stiffening profiles only extend completely over the width of one screen belt fabric and only partially protrude from the central belt into the other screen belt fabric. As a result of the offset arrangement, reinforcing profiles that are adjacent in the longitudinal direction extend alternately either over the left half of the sieve belt arrangement or over the right half of the sieve belt arrangement. This makes it possible to achieve different divisions of the working width and, in particular, to combine screen belt fabrics with different widths arranged parallel to one another.

In weiterer Ausgestaltung der Erfindung sind am Mittelriemen quer erstreckte Stützstäbe befestigt, die sich zu gleichen Teilen in die beiden benachbarten Siebbandgewebe hinein erstrecken. Die Stützstäbe dienen zur Verstärkung des Mittelbereichs der Siebbandanordnung. Sie ragen T-förmig vom Mittelriemen aus in die beiden links und rechts benachbarten Siebbandgewebe hinein. Dabei sind die Stützstäbe in gleicher Weise durch entsprechende Schlaufen der Tressengewebe der Siebbandgewebe hindurch erstreckt wie dies bei den Versteifungsprofilen der Fall ist.In a further embodiment of the invention, transversely extending support rods are attached to the central belt, which extend equally into the two adjacent screen belt fabrics. The support rods serve to reinforce the central area of the sieve belt arrangement. They protrude in a T-shape from the central belt into the two adjacent mesh belt meshes on the left and right. The support rods are extended in the same way through corresponding loops of the braid fabric of the screen belt fabric, as is the case with the reinforcement profiles.

Für das Strandreinigungsfahrzeug wird die der Erfindung zugrunde liegende Aufgabe dadurch gelöst, dass ein Siebbandsystem mit wenigstens einem der zuvor beschriebenen Merkmale vorgesehen ist. Ein derartiges Strandreinigungsfahrzeug kann ein geschlepptes Fahrzeug entsprechend der in der DE 10 2010 006 278 A1 beschriebenen Gattung oder ein Selbstfahrer entsprechend der in der DE 10 113 702 B4 beschriebenen Variante sein.For the beach cleaning vehicle, the object on which the invention is based is achieved in that a sieve belt system with at least one of the features described above is provided. Such a beach cleaning vehicle can be a towed vehicle in accordance with that shown in FIG DE 10 2010 006 278 A1 type described or a self-propelled vehicle according to the DE 10 113 702 B4 described variant.

Ein Strandreinigungsfahrzeug 1 gemäß Fig. 1 ist dazu vorgesehen, von einem Schlepper geschleppt zu werden. Das Strandreinigungsfahrzeug 1 weist eine einzelne Radachse auf. Das Strandreinigungsfahrzeug 1 dient dazu, ein Sand-Schmutz-Gemisch entlang eines Sandstrands aufzunehmen und auf einem Siebbandsystem nach hinten zu transportieren, wobei kleine Partikel wie insbesondere Sand durch eine Siebbandanordnung 2 des Siebbandsystems hindurch wieder nach unten auf den Sandboden fallen können, wohingegen größerer Schmutz wie Abfall, angeschwemmtes Treibgut und Ähnliches über das Siebbandsystem nach hinten in einen Schmutzbehälter transportiert werden.A beach cleaning vehicle 1 according to Fig. 1 is intended to be towed by a tractor. The beach cleaning vehicle 1 has a single wheel axle. The beach cleaning vehicle 1 is used to pick up a sand-dirt mixture along a sandy beach and to transport it to the rear on a sieve belt system, whereby small particles such as sand in particular can fall back down through a sieve belt arrangement 2 of the sieve belt system, whereas larger dirt can fall back down onto the sandy bottom such as rubbish, floating debris and the like are transported backwards into a dirt container via the sieve belt system.

Das Siebbandsystem weist eine endlos umlaufende Siebbandanordnung 2 auf, die front- und rückseitig über jeweils eine Umlenkwelle 3, 4 umgelenkt ist. Die Umlenkwelle 3 ist als Antriebswelle ausgeführt, die von einer nicht näher dargestellten Antriebseinheit angetrieben ist. Ein Untertrum der Siebbandanordnung 2 ist zudem über zwei Führungswalzen 5, 6 geführt. Ein eben gespanntes Obertrum der Siebbandanordnung 2 wird durch mehrere Rüttelwalzen 7 beaufschlagt, die eine Trennung des Sand-Schmutz-Gemisches verbessern. Anhand der Fig. 2 bis 9 wird nachfolgend die Siebbandanordnung 2 detailliert beschrieben.The sieve belt system has an endlessly revolving sieve belt arrangement 2, which is deflected on the front and back via a respective deflection shaft 3, 4. The deflection shaft 3 is used as a drive shaft executed, which is driven by a drive unit not shown. A lower strand of the screen belt arrangement 2 is also guided over two guide rollers 5, 6. A just tensioned upper run of the screen belt arrangement 2 is acted upon by several vibrating rollers 7, which improve a separation of the sand-dirt mixture. Based on Figures 2 to 9 the sieve belt arrangement 2 is described in detail below.

Die Siebbandanordnung 2 läuft in Längsrichtung des Strandreinigungsfahrzeugs 1 endlos um. Anhand der Fig. 2 bis 9 ist die Siebbandanordnung lediglich über einen Teilabschnitt ihrer Länge, jedoch über ihre volle Arbeitsbreite detailliert dargestellt und beschrieben. Die Gestaltung der Siebbandanordnung 2 ändert sich über die nicht dargestellten Abschnitte und Bereiche nicht, so dass das Nachfolgende für die gesamte Siebbandanordnung 2 gilt.The screen belt arrangement 2 revolves endlessly in the longitudinal direction of the beach cleaning vehicle 1. Based on Figures 2 to 9 the sieve belt arrangement is shown and described in detail only over a section of its length, but over its full working width. The design of the sieve belt arrangement 2 does not change over the sections and areas not shown, so that the following applies to the entire sieve belt arrangement 2.

Die Siebbandanordnung 2 weist zwei parallel nebeneinander angeordnete Siebbandgewebe 8 auf, die beim dargestellten Ausführungsbeispiel die gleiche Breite besitzen und als umlaufende Endlosbahn gestaltet sind. Die beiden Siebbandgewebe 8 sind in Längsrichtung parallel nebeneinander angeordnet. Beide Siebbandgewebe 8 sind identisch gestaltet und als metallisches Tressengewebe hergestellt, bei dem entsprechende metallische Kett- und Schussdrähte dreidimensionale Schlaufen oder Augen bilden. Die beiden Siebbandgewebe 8 sind über ihre gesamte Länge im Bereich der Mitte der Siebbandanordnung 2 mit einem in Längsrichtung umlaufenden Mittelriemen 9 verbunden, der zwischen den benachbarten Siebbandgeweben 8 erstreckt ist. Hierzu erstrecken sich durch entsprechende Schlaufen des Siebbandgewebes 8 hindurch mehrere, in Querrichtung parallel zueinander verlaufende Versteifungsprofile 15, die in gleichmäßiger Teilung in die beiden Siebbandgewebe 8 integriert und auf dem Mittelriemen 9 befestigt sind. Die Versteifungsprofile 15 sind als Metallstäbe, vorzugsweise als Stahlstäbe, gestaltet. Im Bereich des Mittelriemens 9 sind die Versteifungsprofile 15 mit abgeplatteten Bereichen 17 versehen, die jeweils zwei Durchtrittsbohrungen aufweisen. Der Mittelriemen 9 ist analog der Lage der Durchtrittsbohrungen mit entsprechenden Löchern versehen, durch die hindurch mechanische Befestigungsmittel die abgeplatteten Bereiche der Versteifungsprofile mit dem Mittelriemen 9 verbinden.The sieve belt arrangement 2 has two sieve belt fabrics 8 which are arranged parallel to one another and which, in the exemplary embodiment shown, have the same width and are designed as a continuous continuous web. The two screen belt fabrics 8 are arranged parallel to one another in the longitudinal direction. Both screen belt fabrics 8 are designed identically and manufactured as a metallic weave fabric, in which the corresponding metallic warp and weft wires form three-dimensional loops or eyes. The two screen belt fabrics 8 are connected over their entire length in the region of the center of the screen belt arrangement 2 with a central belt 9 which runs around in the longitudinal direction and which extends between the adjacent screen belt fabrics 8. For this purpose, several stiffening profiles 15, running parallel to one another in the transverse direction, extend through corresponding loops of the sieve belt fabric 8, which are evenly divided into the two sieve belt fabrics 8 and attached to the central belt 9. The stiffening profiles 15 are designed as metal bars, preferably as steel bars. In the area of the central belt 9, the stiffening profiles 15 are provided with flattened areas 17 which each have two through-holes. The central belt 9 is provided with corresponding holes, analogous to the position of the through-holes, through which mechanical fastening means connect the flattened areas of the stiffening profiles to the central belt 9.

Wie anhand der Fig. 5 bis 8 erkennbar ist, sind Nietverbindungen 19 vorgesehen, um die abgeplatteten Bereiche 17 der Versteifungsprofile 15 an dem Mittelriemen 9 zu befestigen. Die entsprechenden Nietverbindungen 19 weisen im Bereich einer Unterseite Nietplatten auf. Entsprechende Niete ragen durch die Löcher des Mittelriemens 9 und durch die Durchtrittsbohrungen der abgeplatteten Bereiche der Versteifungsprofile 15 hindurch. Mittels einer entsprechenden Fixierung der Niete erfolgt die gewünschte Befestigung der Versteifungsprofile 15 auf dem Mittelriemen 9.How with the Figures 5 to 8 As can be seen, rivet connections 19 are provided in order to fasten the flattened areas 17 of the stiffening profiles 15 to the central belt 9. The corresponding riveted connections 19 have rivet plates in the area of an underside. Corresponding rivets protrude through the holes in the central belt 9 and through the through-holes in the flattened areas of the stiffening profiles 15. The desired fastening of the reinforcement profiles 15 on the central belt 9 takes place by means of a corresponding fixation of the rivets.

Die Versteifungsprofile 15 erstrecken sich über die gesamte Arbeitsbreite der Siebbandanordnung 2 und sind an ihren gegenüberliegenden Stirnenden mit zwei Außenriemen 10 verbunden, die parallel zu dem Mittelriemen 9 erstreckt sind und das jeweilige Siebbandgewebe 8 außenseitig flankieren. Entsprechende Stirnendbereiche der Versteifungsprofile 15 sind im Bereich der Außenriemen 10 in gleicher Weise abgeplattet und mit Durchtrittsbohrungen versehen, wie dies im Bereich des Mittelriemens der Fall ist. Auch die Außenriemen 10 weisen auf die Durchtrittsbohrungen abgestimmte Löcher auf. In gleicher Weise wie beim Mittelriemen 9 sind auch bei den Außenriemen entsprechende Nietverbindungen 19 vorgesehen, die zur Befestigung der Stirnendbereiche der Versteifungsprofile mit den beiden Außenriemen 10 dienen. Die Befestigung über die Nietverbindungen 19 erfolgt in gleicher Weise wie bei den Mittelriemen 9, so dass auf die Beschreibung zu der Befestigung des Mittelriemens 9 verwiesen wird. Anhand der Fig. 9 ist die Verbindung der Versteifungsprofile 15 mit dem jeweiligen Außenriemen 10 dargestellt.The stiffening profiles 15 extend over the entire working width of the screen belt arrangement 2 and are connected at their opposite end faces to two outer belts 10 which extend parallel to the central belt 9 and flank the respective screen belt fabric 8 on the outside. Corresponding end regions of the stiffening profiles 15 are flattened in the same way in the area of the outer belt 10 and provided with through-holes, as is the case in the area of the central belt. The outer belts 10 also have holes that are matched to the through-holes. In the same way as with the middle belt 9, corresponding rivet connections 19 are also provided for the outer belts, which are used to fasten the end regions of the stiffening profiles to the two outer belts 10. The fastening via the riveted connections 19 takes place in the same way as with the central belt 9, so that reference is made to the description of the fastening of the central belt 9. Based on Fig. 9 the connection of the stiffening profiles 15 with the respective outer belt 10 is shown.

Anhand der Fig. 2 und 5 ist erkennbar, dass die stabförmigen Versteifungsprofile 15 über die gesamte Breite des jeweiligen Siebbandgewebes 8 durch entsprechende Schlaufen des Gewebes hindurchgeführt sind, so dass über die gesamte Breite eine in Längsrichtung formschlüssige Verbindung zwischen den Versteifungsprofilen 15 und dem jeweiligen Siebbandgewebe 8 gegeben ist. Die Versteifungsprofile 15 verhindern demzufolge eine Verschiebung oder Dehnung der Siebbandgewebe 8 in Längsrichtung.Based on Fig. 2 and 5 It can be seen that the rod-shaped stiffening profiles 15 are passed over the entire width of the respective screen belt fabric 8 through corresponding loops of the fabric, so that a form-fitting connection in the longitudinal direction between the stiffening profiles 15 and the respective screen belt fabric 8 is provided over the entire width. The stiffening profiles 15 consequently prevent displacement or stretching of the screen belt fabric 8 in the longitudinal direction.

Um in einem mittleren Bereich der Arbeitsbreite der Siebbandanordnung 2 eine weiter verbesserte Versteifung und Stützung zu erzielen, sind zudem im Bereich des Mittelriemens 9 zwischen den Versteifungsprofilen 15 jeweils alternierend Stützstäbe 16 vorgesehen, die sich ausgehend von dem Mittelriemen 9 über einen Teil der jeweiligen Breite der Siebbandgewebe 8 in diese hinein erstrecken, wodurch ein Mittelstreifen der Siebbandanordnung 2 zusätzlich versteift ist. Die Stützstäbe 16 sind mit abgeplatteten Bereichen 18 versehen, die identisch gestaltet sind wie die abgeplatteten Bereiche 17 der Versteifungsprofile 15. Auch die Stützstäbe 16 sind analog der Versteifungsprofile 15 als Metallprofile, vorliegend als Stahlstäbe, gestaltet, Die abgeplatteten Bereiche 18 sind mit Durchtrittsbohrungen versehen, denen im Bereich des Mittelriemens 9 komplementäre Löcher zugeordnet sind. Nietverbindungen 19 dienen in gleicher Weise zur Befestigung der Stützstäbe an dem Mittelriemen 9, wie diese auch zur Befestigung der Versteifungsprofile 16 an dem Mittelriemen 9 und an den Außenriemen 10 dienen. Die Stützstäbe 19 sind in gleicher Weise durch entsprechende Schlaufen der beiden Siebbandgewebe 8 hindurch erstreckt, wie dies bei den Versteifungsprofilen 15 der Fall ist. Einziger Unterschied ist es, dass die Stützstäbe 16 frei in die Schlaufen der beiden Siebbandgewebe 8 hineinragen und sich lediglich im mittleren Bereich der Siebbandanordnung 2, d. h. im Bereich des Mittelstreifens, erstrecken.In order to achieve further improved stiffening and support in a central area of the working width of the main belt assembly 2, alternating support rods 16 are also provided in the area of the central belt 9 between the stiffening profiles 15, which extend from the central belt 9 over part of the respective width of the Sieve belt fabric 8 extend into this, whereby a central strip of the sieve belt arrangement 2 is additionally stiffened. The support rods 16 are provided with flattened areas 18, which are designed identically to the flattened areas 17 of the stiffening profiles 15. The supporting rods 16 are similar to the stiffening profiles 15 designed as metal profiles, in this case as steel rods, the flattened areas 18 are provided with through holes, which 9 complementary holes are assigned in the area of the central belt. Rivet connections 19 are used in the same way to fasten the support rods to the central belt 9, as they are also used to fasten the stiffening profiles 16 to the central belt 9 and to the outer belt 10. The support rods 19 are extended in the same way through corresponding loops of the two screen belt fabrics 8, as is the case with the stiffening profiles 15. The only difference is that the support rods 16 protrude freely into the loops of the two screen belt fabrics 8 and only extend in the central area of the screen belt arrangement 2, ie in the area of the central strip.

Anhand der Fig. 2 bis 9 ist auch erkennbar, dass sowohl der Mittelriemen 9 als auch die Außenriemen 10 im Bereich ihrer den Umlenkwellen 3, 4 zugewandten Innenseiten mit Profilierungen in Form von Nocken 12, 13 versehen sind. Der Mittelriemen 9 ist mit den Nocken 12 im Bereich seiner Innenseite versehen. Im Bereich der Außenseite weist der Mittelriemen 9 eine im Wesentlichen ebene Fläche auf, auf der die abgeplatteten Bereiche 17, 18 der Versteifungsprofile 15 und der Stützstäbe 16 befestigt sind. Die Außenriemen 10 hingegen sind auch im Bereich ihrer Außenseite, d.h. gegenüberliegend zu den Nocken 13 der Innenseite, mit Zusatznocken 14 versehen, die in identischer Weise in Querrichtung erstreckt sind wie die Nocken 13, 12 der Außenriemen 10 und des Mittelriemens 9. Anhand der Fig. 3 ist eine erfindungsgemäße Variante gezeigt, bei der die als Antriebswelle dienende Umlenkwelle 3a mit drei als Außenprofilierungen dienende Außennocken versehene Antriebsräder 11 umfasst, die drehfest auf einer gemeinsamen Welle gehalten sind. Die Außennocken der Antriebsräder 11 sind komplementär zu den Nocken 12, 13 gestaltet und dienen dazu, formschlüssig in die Nocken 12, 13 des Mittelriemens 9 und der Außenriemen 10 einzugreifen und so einen formschlüssigen, schlupffeien Transport der Siebbandanordnung 2 im Bereich der Antriebswelle 3a zu erzielen. Bei der in Fig. 1 dargestellten Ausführungsform ist die als Antriebswelle dienende Umlenkwelle 3 durch eine Antriebswalze gebildet, die an ihrem Außenmantel mit einer Gummierung versehen ist.Based on Figures 2 to 9 it can also be seen that both the central belt 9 and the outer belt 10 are provided with profiles in the form of cams 12, 13 in the area of their inner sides facing the deflection shafts 3, 4. The central belt 9 is provided with the cams 12 in the area of its inside. In the area of the outside, the central belt 9 has an essentially flat surface on which the flattened areas 17, 18 of the stiffening profiles 15 and the support rods 16 are attached. The outer belts 10, on the other hand, are also provided with additional cams 14 in the area of their outside, ie opposite the cams 13 on the inside, which extend in an identical manner in the transverse direction as the cams 13, 12 of the outer belt 10 and the center belt 9 Fig. 3 a variant according to the invention is shown in which the deflecting shaft 3a serving as a drive shaft comprises drive wheels 11 which are provided with three external cams serving as external profiles and which are held in a rotationally fixed manner on a common shaft. The outer cams of the drive wheels 11 are designed complementary to the cams 12, 13 and serve to positively engage the cams 12, 13 of the central belt 9 and the outer belt 10 and thus achieve a positive, slip-free transport of the screen belt assembly 2 in the area of the drive shaft 3a . At the in Fig. 1 The embodiment shown, the deflecting shaft 3 serving as a drive shaft is formed by a drive roller which is provided with a rubber coating on its outer surface.

Die Zusatznocken 14 an den Außenseiten der Außenriemen 10 sind dazu vorgesehen, einen verbesserten Transport der Siebbandanordnung 2 im Bereich der Führungswalzen 6, 7 zu erzielen, über die die Siebbandanordnung 2 hinweggeführt ist. Zudem dienen die Zusatznocken 14 als Schutz gegen vorzeitigen Verschleiß der Außenriemen 10.The additional cams 14 on the outer sides of the outer belts 10 are provided to achieve an improved transport of the sieve belt arrangement 2 in the area of the guide rollers 6, 7 over which the sieve belt arrangement 2 is guided. In addition, the additional cams 14 serve as protection against premature wear of the outer belts 10.

Auch die Umlenkwelle 4 kann in gleicher Weise wie die Umlenkwelle 3a mit Walzen oder Rädern versehen sein, die an ihrem Außenumfang Außennocken aufweisen, die komplementär zu den Zusatznocken 14 der Außenriemen 10 gestaltet sind.The deflecting shaft 4 can also be provided, in the same way as the deflecting shaft 3a, with rollers or wheels which have outer cams on their outer circumference, which are designed to complement the additional cams 14 of the outer belts 10.

Eine Siebbandanordnung 2' gemäß Fig. 10 ist in gleicher Weise bei einem Siebbandsystem eines Strandreinigungsfahrzeugs gemäß Fig. 1 einsetzbar, wie dies das Siebbandsystem gemäß den Fig. 2 bis 9 ist. Wesentlicher Unterschied des Siebbandsystems gemäß Fig. 10 ist es, dass die Siebbandanordnung 2' eine geringere Arbeitsbreite aufweist als die Siebbandanordnung 2 gemäß Fig. 3. Aufgrund der reduzierten Arbeitsbreite genügt es daher, lediglich ein einzelnes Siebbandgewebe 8' vorzusehen, das in gleicher Weise als metallisches Tressengewebe ausgeführt ist wie die zuvor beschriebenen Siebbandgewebe 8. Zur Vermeidung von Wiederholungen wird auf die Ausführungen zu dem Siebbandsystem gemäß den Fig. 2 bis 9 verwiesen. Funktionsgleiche Teile oder Abschnitte sind mit gleichen Bezugszeichen unter Hinzufügen eines Hochstrichs versehen. Auch die Siebbandanordnung 2' ist an ihren gegenüberliegenden Längsseiten, in Transportrichtung, d. h. in Umlaufrichtung der Siebbandanordnung 2' gesehen, mit zwei Außenriemen 10' versehen, die identisch gestaltet sind wie die Außenriemen 10 der Siebbandanordnung 2 gemäß Fig. 3. Die Siebbandanordnung 2' benötigt aufgrund der geringeren Arbeitsbreite keinen Mittelriemen. Auch die Siebbandanordnung 2' wird umlaufend angetrieben durch mit Außenprofilierungen in Form von Außennocken versehene Antriebsräder 11', die drehfest auf einer gemeinsamen Welle gehalten sind. Die Antriebsräder 11' und die Welle bilden die angetriebene Umlenkwelle 3', die in dem Strandreinigungsfahrzeug analog positioniert ist wie die Umlenkwelle 3 gemäß Fig. 1. Die beiden Antriebsräder 11' treiben über die nicht dargestellte Antriebseinheit synchron und schlupffrei die beiden Außenriemen 10' der Siebbandanordnung 2' an. Hierzu weisen die Außenriemen 10' Profilierungen 13' auf, die komplementär zu den Außenprofilierungen der Antriebsräder 11' gestaltet sind. In Umfangsrichtung der Antriebsräder 11' und damit in Förderrichtung der Außenriemen 10' greifen die Profilierungen 13' und die Außenprofilierungen der Antriebsräder 11' formschlüssig ineinander. Die Profilierungen 13' sind nockenförmig ausgeführt, wobei die Nocken sich über eine gesamte Breite des jeweiligen Außenriemens 10' in Querrichtung erstrecken. Die Außenprofilierungen der Antriebsräder 11' sind nach Art von Stirnnocken auf dem Außenumfang des jeweiligen Antriebsrades 11' vorgesehen und erstrecken sich jeweils ebenfalls in Querrichtung. Die beiden Außenriemen 10' sind mit entsprechenden Längsrändern des Siebbandgewebes 8' über mehrere, quer verlaufende Versteifungsprofile 15' verbunden. Die Versteifungsprofile 15' sind in gleichmäßiger Teilung über die Länge des Siebbandgewebes 8' angeordnet und erstrecken sich in Querrichtung jeweils über die gesamte Arbeitsbreite des Siebbandgewebes 8'. Die Versteifungsprofile 15' sind stabförmig gestaltet und sind an ihren gegenüberliegenden Stirnendbereichen abgeplattet und über mechanische Befestigungsmittel in Form von Nietverbindungen mit dem jeweiligen Außenriemen 10' verbunden analog der Verbindung der Versteifungsprofile 15 mit den Außenriemen 10 bzw. dem Mittelriemen 9 bei der zuvor beschriebenen Ausführungsform. Auch hier wird zur Vermeidung von Wiederholungen auf die ausführlich beschriebene Befestigung der Versteifungsprofile 15 mit den Außenriemen 10 bzw. dem Mittelriemen 9 verwiesen. Die Versteifungsprofile 15' sind stabförmig gestaltet und durch entsprechende Augen oder Schlaufen des metallischen Tressengewebes in Querrichtung hindurchgeführt, so dass das entsprechende Hindurchschlaufen eine formschlüssige Verbindung zwischen den Versteifungsprofilen 15' und dem Siebbandgewebe 8' in Transportrichtung des Siebbandgewebes 8' ergeben. Die an den Außenriemen 10' befestigten Versteifungsprofile 15' bewirken beim entsprechenden Fördern der Außenriemen 10' durch die Antriebsräder 11' zwangsläufig eine Mitnahme des Siebbandgewebes 8' in Förderrichtung, da die Versteifungsprofile 15' über die gesamte Arbeitsbreite des Siebbandgewebes 8' mit diesem verankert sind. Hierdurch wird eine schlupffreie und synchrone Förderung der umlaufenden Siebbandanordnung 2' in Umlaufrichtung erzielt. Ein Durchhängen des Siebbandgewebes 8' zur Mitte hin wird in gleicher Weise vermieden wie eine ungleichmäßige Längung des Siebbandgewebes 8' in Transportrichtung, d. h. in Umlaufrichtung. A sieve belt arrangement 2 'according to Fig. 10 is in the same way according to a sieve belt system of a beach cleaning vehicle Fig. 1 can be used, as the sieve belt system according to Figures 2 to 9 is. Essential difference of the main belt system according to Fig. 10 it is that the sieve belt arrangement 2 'has a smaller working width than the sieve belt arrangement 2 according to FIG Fig. 3 . Due to the reduced working width, it is therefore sufficient to provide only a single sieve belt fabric 8 ', which is designed in the same way as a metallic weave fabric as the sieve belt fabric 8 described above. To avoid repetition, reference is made to the statements on the sieve belt system according to Figures 2 to 9 referenced. Functionally equivalent parts or sections are provided with the same reference numerals with the addition of a prime. The sieve belt arrangement 2 'is also located opposite one another Long sides, seen in the transport direction, ie in the direction of rotation of the screen belt arrangement 2 ', are provided with two outer belts 10' which are designed identically to the outer belts 10 of the screen belt arrangement 2 according to FIG Fig. 3 . The main belt arrangement 2 'does not require a central belt due to the smaller working width. The sieve belt arrangement 2 'is also driven in a circumferential manner by drive wheels 11' which are provided with external profiles in the form of external cams and are held in a rotationally fixed manner on a common shaft. The drive wheels 11 'and the shaft form the driven deflection shaft 3', which is positioned in the beach cleaning vehicle in the same way as the deflection shaft 3 according to FIG Fig. 1 . The two drive wheels 11 'drive the two outer belts 10' of the sieve belt arrangement 2 'synchronously and without slipping via the drive unit (not shown). To this end, the outer belts 10 'have profiles 13' which are designed to be complementary to the outer profiles of the drive wheels 11 '. In the circumferential direction of the drive wheels 11 'and thus in the conveying direction of the outer belts 10', the profiles 13 'and the outer profiles of the drive wheels 11' interlock in a form-fitting manner. The profiles 13 'are designed in the form of cams, the cams extending over an entire width of the respective outer belt 10' in the transverse direction. The outer profiles of the drive wheels 11 'are provided in the manner of end cams on the outer circumference of the respective drive wheel 11' and each also extend in the transverse direction. The two outer belts 10 'are connected to corresponding longitudinal edges of the screen belt fabric 8' via a plurality of transverse reinforcement profiles 15 '. The stiffening profiles 15 'are evenly spaced over the length of the screen belt fabric 8' and extend in the transverse direction over the entire working width of the screen belt fabric 8 '. The stiffening profiles 15 'are rod-shaped and are flattened at their opposite end areas and connected to the respective outer belt 10' via mechanical fastening means in the form of riveted connections, analogous to the connection of the stiffening profiles 15 with the outer belt 10 or the central belt 9 in the embodiment described above. Here, too, to avoid repetition, reference is made to the fastening of the stiffening profiles 15 with the outer belt 10 or the central belt 9, as described in detail. The stiffening profiles 15 'are rod-shaped and passed through corresponding eyes or loops of the metallic braid fabric in the transverse direction, so that the corresponding looping results in a positive connection between the stiffening profiles 15' and the sieve belt fabric 8 'in the transport direction of the sieve belt fabric 8'. When the outer belts 10 'are conveyed by the drive wheels 11', the stiffening profiles 15 'attached to the outer belt 10' inevitably entrain the screen belt fabric 8 'in the conveying direction, since the stiffening profiles 15' are anchored to the screen belt fabric 8 'over the entire working width thereof . As a result, a slip-free and synchronous conveyance of the rotating sieve belt arrangement 2 'in the direction of rotation is achieved. A sagging of the screen belt fabric 8 'towards the middle is avoided in the same way as an uneven elongation of the screen belt fabric 8 'in the transport direction, ie in the direction of rotation.
