Description

Die Erfindung betrifft einen Siebboden mit dünnen, flächigen Siebmatten aus gummielastischem Material, die von darunter angeordneten Profilen gehalten werden, an deren Oberseiten die Siebmatten unter Zugspannung lösbar befestigt sind.The invention relates to a sieve plate with thin, flat sieve mats made of rubber-elastic material, which are held by profiles arranged underneath, on the upper sides of which the sieve mats are releasably fastened under tension.

Zum Befestigen von Siebböden sind die verschiedensten Maßnahmen bekannt. So ist es beispielsweise aus der DE-A-37 21 062 bekannt, die Siebfläche vor ihrer Befestigung am Siebrahmen zu erwärmen und dann den Siebmattenrand aufzukleben. Eine solche Befestigung der Siebmatte ringsum über die gesamte Randlänge ist erforderlich, da die Siebmatten verhältnismäßig dünn sind und damit keine ausreichende Eigenstabilität besitzen. Nur durch eine Befestigung über die gesamte Randlänge wird ein ausreichender Halt geboten. Eine solche Befestigung ist arbeitsaufwendig und kann von den Anwendern einer Siebmaschine nicht durchgeführt werden. Ferner hat es sich gezeigt, daß nach der Erkaltung der Siebmatte diese oft nicht genügend Spannung aufweist, so daß sie im Einsatz durchhängt.Various measures are known for fastening sieve trays. For example, it is known from DE-A-37 21 062 to heat the sieve surface before it is attached to the sieve frame and then to glue on the edge of the sieve mat. Such attachment of the sieve mat all over the entire edge length is necessary because the sieve mats are relatively thin and therefore do not have sufficient inherent stability. Sufficient support is only provided by fastening over the entire edge length. Such fastening is labor-intensive and cannot be carried out by the users of a screening machine. Furthermore, it has been shown that after the screen mat has cooled, it often does not have sufficient tension so that it sags in use.

Aufgabe der Erfindung ist es einen Siebboden der eingangs genannten Art so zu verbessern, daß bei einfacher Konstruktion und Handhabung, insbesondere bei leichter Auswechselbarkeit, eine ausreichende Spannung der Siebmatten erzielt wird.The object of the invention is to improve a sieve tray of the type mentioned in such a way that with simple construction and handling, in particular with easy interchangeability, sufficient tension of the sieve mats is achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Profile an der Oberseite eine Längsausnehmung aufweisen, in die die Siebmatten zusammen mit einer Schnur eindrückbar sind, die auf der Oberseite der Siebmatten liegt, wobei die Breite der Längsausnehmung geringer ist als der Durchmesser der Schnur plus der zweifachen Siebmattendicke.This object is achieved in that the profiles have a longitudinal recess on the top, into which the screen mats can be pressed together with a cord that lies on the top of the screen mats, the width of the longitudinal recess being less than the diameter of the cord plus twice the mat size.

Bei dieser Befestigungsweise braucht die Siebmatte nur ohne Spannung oder mit verhältnismäßig geringer Spannung auf die Profile gelegt zu werden und danach werden die Schnüre in die Längsausnehmungen der Profile eingedrückt, wodurch dann erst die eigentliche Spannung von ausreichender Stärke geschaffen wird. Eine solche Befestigung ist konstruktiv einfach und leicht durchführbar. Auch brauchen die Siebmatten selber keine aufwendige Bauweise besitzen. Sie benötigen weder an der Ober- noch an der Unterseite Vorsprünge. Außerdem wird im Vergleich zu anderen Siebböden teures Kunststoffmaterial gespart. Der Basis-Boden mit den Profilen ist mehrfach verwendbar.With this type of attachment, the sieve mat only needs to be placed on the profiles without tension or with relatively little tension and then the cords are pressed into the longitudinal recesses of the profiles, which then creates the actual tension of sufficient strength. Such an attachment is structurally simple and easy to carry out. The screen mats themselves do not need to be of complex construction. You don't need protrusions on either the top or bottom. In addition, expensive plastic material is saved compared to other sieve trays. The base floor with the profiles can be used several times.

Eine besonders einfache und sichere Befestigung wird dann erreicht, wenn die Schnur aus gummielastischem Material besteht. Auch kann hierzu die Schnur einen kreisförmigen Querschnitt aufweisen.A particularly simple and secure attachment is achieved when the cord is made of rubber-elastic material. For this purpose, the cord can also have a circular cross section.

Aus der AT-B-344 630 ist es an sich bekannt, Tragprofile mit Längsschlitzen an der Oberseite zu versehen, um Siebelemente großer Dicke und Steifigkeit durch an der Unterseite angeordnete Fortsätze zu befestigen, die in die Längsausnehmungen paarweise eingreifen. Ferner ist es bekannt, durch Rundschnüre und Längsausnehmungen zahlreich nebeneinanderliegende Gummischnüre zu befestigen um hierdurch einen Gummispalt-Siebboden herzustellen.From AT-B-344 630 it is known per se to provide support profiles with longitudinal slots on the top in order to fasten screen elements of great thickness and rigidity by means of extensions arranged on the underside which engage in pairs in the longitudinal recesses. Furthermore, it is known to attach numerous adjacent rubber cords by round cords and longitudinal recesses to thereby produce a rubber slotted screen.

Besonders vorteilhaft ist es, wenn das Profil ein Hohlprofil ist. Hierbei sollte das Profil im Querschnitt U-förmig sein, wobei die oberen freien Schenkelenden etwa waagerecht nach innen umgebogen sind. Vorzugsweise wird vorgeschlagen, daß die Siebmatten aus einem Band großer Länge bestehen, das in die gewünschten Längen teilbar ist. Damit sind die Siebmatten besonders preiswert als Meterware herstellbar. Ein besonders sicherer Halt und die Vermeidung von Verschmutzungsgefahr des Inneren der Profile ist dann erreichbar, wenn die Siebmatten an den Befestigungsbereichen keine Sieböffnungen besitzen.It is particularly advantageous if the profile is a hollow profile. Here, the profile should be U-shaped in cross-section, the upper free leg ends being bent approximately horizontally inwards. It is preferably proposed that the screen mats consist of a band of great length that can be divided into the desired lengths. This makes the screen mats particularly inexpensive to manufacture by the meter. A particularly secure hold and the avoidance of contamination of the interior of the profiles can be achieved if the screen mats have no screen openings in the fastening areas.

Ein vorteilhaftes Verfahren zum Befestigen der Siebmatten auf dem Siebboden wird dann erreicht, wenn die Siebmatte auf die Profiloberseite lose oder unter leichter Spannung aufgelegt wird und durch die Schnüre von oben in die Längsausnehmungen unter Mitnahme der Siebmatten gedrückt wird.An advantageous method for attaching the sieve mats to the sieve bottom is achieved if the sieve mat is placed loosely or under slight tension on the top of the profile and is pressed through the cords from above into the longitudinal recesses while taking the sieve mats with them.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Draufsicht auf den Siebboden im Ausschnitt bei abgenommener Siebmatte und
  • Fig. 2 einen Schnitt nach II-II in Fig. 1 bei befestigter Siebmatte.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • Fig. 1 is a plan view of the sieve bottom in a cutout with the sieve mat and removed
  • Fig. 2 shows a section according to II-II in Fig. 1 with the screen mat attached.

Der Siebboden weist mehrere parallel zur Siebmattenoberseite angeordnete Tragprofile 1 auf, die parallel zueinander in regelmäßigen Abständen angeordnet sind. An den Enden sind die Profile 1 durch Querprofile 2 aneinander befestigt. Unterhalb dieses Profils 1 ist noch ein Stützprofil 3 mit L-förmigem Querschnitt bei gleicher Schenkellänge angeschweißt.The sieve bottom has a plurality of support profiles 1 arranged parallel to the top of the sieve mat, which are arranged parallel to one another at regular intervals. At the ends of the profiles 1 are fastened to one another by cross profiles 2. Below this profile 1, a support profile 3 with an L-shaped cross section is welded with the same leg length.

Die Tragprofile 1 sind Hohlprofile mit quadratischem Querschnitt, wobei die waagerechte Oberseite des Profils eine mittige Längsöffnung 4 besitzt, die sich über die gesamte Länge des Profils 1 erstreckt.The support profiles 1 are hollow profiles with a square cross section, the horizontal top of the profile having a central longitudinal opening 4 which extends over the entire length of the profile 1.

Über die Profile 1 werden Siebmatten 5 als Spannmatten gelegt, die als Meterware endlos aus Kunststoff, insbesondere Polyurethan hergestellt werden und in einer Länge abgeschnitten werden, die der Breite B des Siebbodens entsprechen, wobei die Siebmatte noch etwas länger geschnitten wird um sie seitlich an den beiden Enden am ersten und letzten Profil seitlich durch Schrauben 7 anklemmen zu können. Die so lose über alle Profile 1 gelegte Siebmatte liegt damit auch über den Öffnungen 4.Over the profiles 1, sieve mats 5 are placed as tensioning mats, which are manufactured by the meter from plastic, in particular polyurethane, and are cut to a length which corresponds to the width B of the sieve bottom, the sieve mat being cut a little longer to laterally connect it to the to be able to clamp both ends on the first and last profile laterally with screws 7. The sieve mat so loosely placed over all profiles 1 thus also lies over the openings 4.

Es kann dann von oben in die Öffnungen 4 eine Rundschnur 6 eingedrückt werden, die dann den dort liegenden Bereich der Siebmatte 5 mitnimmt in das Innere des Profils. Der Durchmesser der Schnur 6 zusammen mit der zweifachen Dicke der Siebmatte 5 ergibt ein Maß M, das größer ist als die Breite der Öffnung 4, so daß nach dem Eindrücken der Schnur 6 und des dazu gehörenden Bereichs der Siebmatte 5 ein rastender Halt der Siebmatte 5 am Profil 1 gegeben ist.A round cord 6 can then be pressed into the openings 4 from above, which then takes the area of the screen mat 5 lying there into the interior of the profile. The diameter of the cord 6 together with twice the thickness of the screen mat 5 gives a dimension M which is greater than the width of the opening 4, so that after the cord 6 and the associated area of the screen mat 5 have been pressed in, the screen mat 5 is held in place is given on profile 1.

Da ein größerer Abschnitt bzw. ein größeres Längenstück der Siebmatte 5 im Bereich dieses Profils 1 benötigt wird, wird durch das Eindrücken solcher mehrerer Schnüre 6 eine ausreichend hohe Spannung der Siebmatte 5 erreicht.Since a larger section or a larger length of the screen mat 5 is required in the area of this profile 1, a sufficiently high tension of the screen mat 5 is achieved by pressing in such a plurality of cords 6.

Besonders günstig ist es, wenn die Siebmattenbereiche, die zur Befestigung an den Profilen 1 durch die Schnüre 6 verwendet werden, keine Sieböffnungen besitzen. In weiteren nicht ausgeführten Ausführungsbeispielen können die Profile 1 auch wesentlich abweichende Querschnitte haben, insbesondere rechteckig oder kreisförmig sein. Auch braucht die Schnur 6 nicht unbedingt einen kreisförmigen Querschnitt besitzen.It when the sieve mat areas, the used for attachment to the profiles 1 by the cords 6, have no sieve openings. In further exemplary embodiments which have not been carried out, the profiles 1 can also have substantially different cross sections, in particular be rectangular or circular. The cord 6 does not necessarily have to have a circular cross section.
