Definitions
- the invention relates to a screen with webs whose web surfaces are normal to the screen surface and parallel to each other, and with profiles that are partially parallel to the screen surface, the webs on their side facing away from the top of the screen incisions in which the profiles, the their sieves facing the top of the screen have incisions, are inserted, according to the preamble of claim 1.
- Such screens are used in particular in Vibrationssiebmaschinen and for the Altstofftrennung.
- the task side is arranged for the good to be separated near the top and the overflow side is formed at the bottom.
- the top of the sieve is the one on which the oversize rolls off, the bottom is the one from which the through-hole, the sieve passage, falls off.
- the terms top or bottom of the screen, task side or overflow side, are used in the application in this sense.
- a non-generic modification of such screens in which the screen surface is in the form of a cylinder jacket, is from the EP 1 163 835 A and in similar form from the US 4,004,404 , each known as a separator for combine harvester.
- rake-like, angled structures are mounted in the direction of the generatrix of the cylinder jacket between cheeks and through it patch, suitably bent curved round rods extending in the circumferential direction of the cylinder jacket, a support surface for the overlying layer of material is formed.
- This construction is suitable for the separation of straws, etc., but not for bulkier goods.
- Similar but not generic sieves are also from the AT 505 122 B known.
- a sieve plate lying in the plane of the sieve has sieve openings, and in the region of the circumference of the sieve openings, downwardly projecting webs, aprons or guide surfaces are provided, by which the hanging of elongate material such as tapes, cables, etc. is prevented. Since Steckkom can only get stuck in the area of the sieve opening, where it is easily accessible, the above problem does not occur. However, this construction is not very suitable for heavy use because of the not very resistant to bending screen plate and gives away a lot of space between the screen openings.
- the invention has the object to provide a screen of the structure mentioned above for small screen openings available that does not have the problems mentioned, without losing the benefits of such screens.
- strips are fixed, the width of which is greater than the thickness of the webs. At least some of the strips and / or webs are connected, preferably welded, to the regions of at least some of the profiles which have a bent or bent cross-section and thus fix the webs in the profiles. It is not necessary to create a connection between each profile and each bar. Through the strips is further reduced the cross section of each nozzle or downpipe for the passage grain in its uppermost region in which the fürgangsskom occurs, so that it hardly comes to the formation of Steckkom. Even if it comes to it, it remains stuck in the top area, where it is easily accessible.
- the bar is a mechanical reinforcement of the upper edge of each bar and thus increases the life of the sieve. It is to be understood that prior art reinforcing bars, as used variously in screens consisting of perforated plates, are always located outside the area of the screen openings.
- screen surface so that not only the surface formed by the uppermost points of the webs or strips and / or profiles, which may be flat, but possibly also cylindrically curved is meant, but all parallel Surfaces, as the term in the description and the claims serves only as a reference to indicate the position and orientation of the webs or profiles. It could also be used the area, which is defined by the centers of gravity of the individual webs and profiles, and which runs parallel to the surface according to the first definition in a technically sufficient extent. In the knowledge of the invention, it is easy for the skilled person to set the screen area for each design case in the most favorable manner.
- the invention will be explained in more detail below with reference to the drawing.
- the single figure shows a perspective view of a small section of a screen according to the invention.
- a web 1 with an applied bar 2 in a perspective view is shown purely schematically.
- the strip 2 is provided in the illustrated embodiment with a square cross-section, runs along the upper edge 7 of the web 1 and is connected to some or all profiles, for example, welded or glued. For reasons of clarity, it has been dispensed with depicting the connection, for example weld beads or adhesive surfaces.
- the upper edge of the web 1 and / or the side surface of the cutout 9 of the profiles for example by grinding or milling, be contoured, which is adapted to the cross-section of the bar 2 and thus increases the contact area with the bar, but usually point welds are sufficient.
- the slots 3 can be seen, which serve for the plug connection of the webs 1 with the profiles 4.
- the shape and size of these slots 3 corresponds to the cross section of the profiles 4, which also have slots, namely counter slots 8.
- the screen is formed by the parallel arrangement of a corresponding number of webs 1 with aligned slots 3 and the insertion of a corresponding number of profiles 4 in the slots 3 at the points where they have the counter slots 8. This construction is fixed on the one hand by introduction into a correspondingly solid frame, on the other hand by the connection of the strips 2 with the profiles. 4
- the screen surface is defined for example by the surface, which is formed by the plurality of mutually parallel upper edges 6 of the strips 2. It can be clearly seen that this definition, which is only about the orientation of the plane but not about its altitude, could also be done through the surfaces 5.
- cross-sectional shape of the bar 2 for example, the circular cross-section, but also the elliptical cross-section, the use of which will only justify the additional costs in special cases; it is also possible to have isosceles, for example right-angled triangles, the triangular shape can vary from this shape to approximately the equilateral triangle, to use more acute angles on both sides, is hardly recommended for mechanical reasons; Finally, rectangular cross-sections that are T-shaped placed on the web 1, possible.
- the ratio of the thickness of the web 1 to the largest normal to extending dimension of the bar 2 may be different than shown, it may be the cross-sectional shape of the profiles 4 other than in the illustrated embodiment (bent instead of folded) and it can the arrangement (angular position ) and the spacing of the slots 3 in the webs 1 and / or the spacing of the counter slots 8 in the profiles are selected differently than in the illustrated embodiment.
- the screen lining receives a seal of numerous, albeit small, columns resulting from the plug-in system result, and thus also prevents the sticking of various materials such as wires, threads, tapes and the like.
- the largest width of the strips 2 have a significantly greater thickness B compared to the web thickness D, preferably at least twice the thickness and particularly preferably at least four times the thickness of the web.

Abstract
Description
Die Erfindung betrifft ein Sieb mit Stegen, deren Stegflächen normal zur Siebfläche und parallel zueinander verlaufen, und mit Profilen, die teilweise parallel zur Siebfläche verlaufen, wobei die Stege an ihrer der Oberseite des Siebes abgewandten Seite Einschnitte aufweisen, in die die Profile, die an ihrer der Oberseite des Siebes zugewandten Seite Einschnitte aufweisen, eingeschoben werden, entsprechend dem Oberbegriff des Anspruches 1. Derartige Siebe werden insbesondere in Vibrationssiebmaschinen und für die Altstofftrennung eingesetzt.The invention relates to a screen with webs whose web surfaces are normal to the screen surface and parallel to each other, and with profiles that are partially parallel to the screen surface, the webs on their side facing away from the top of the screen incisions in which the profiles, the their sieves facing the top of the screen have incisions, are inserted, according to the preamble of
Derartige Siebe sind bekannt und haben sich im Großen und Ganzen bewährt. Problematisch ist, dass es nicht gelingt, die Durchgangsöffnungen kleiner als etwa 35 mm zu machen, da es dann nicht mehr möglich ist, die Stege mit den Profilen passend zu verschweißen.Such sieves are known and have proven themselves on the whole. The problem is that it is not possible to make the through holes smaller than about 35 mm, since it is then no longer possible to weld the webs to the profiles suitable.
Eine Lösung dieses Problems ist aus der
Zumeist werden derartige Siebe leicht geneigt angeordnet, um dem Überkorn das Abrollen vom Sieb zu ermöglichen. Dementsprechend ist die Aufgabeseite für das zu trennende Gut nahe dem oberen Rand angeordnet und die Überlaufseite entsteht am unteren Rand. Die Oberseite des Siebs ist die, auf der das Überkorn abrollt, die Unterseite ist die, von der das Durchkom, der Siebdurchgang, abfällt. Die Begriffe Oberseite bzw. Unterseite des Siebes, Aufgabeseite bzw. Überlaufseite, werden in der Anmeldung in diesem Sinn benutzt.In most cases, such screens are arranged slightly inclined in order to allow the oversize grain to roll off the wire. Accordingly, the task side is arranged for the good to be separated near the top and the overflow side is formed at the bottom. The top of the sieve is the one on which the oversize rolls off, the bottom is the one from which the through-hole, the sieve passage, falls off. The terms top or bottom of the screen, task side or overflow side, are used in the application in this sense.
Ein Problem aller gattungsgemäßen, aber auch ähnlicher Siebe, bei denen durch die Teile der Profile, die nicht parallel zur Siebfläche verlaufen, gemeinsam mit den Stegen eine Art Fallrohr oder Stutzen für jede Sieböffnung entsteht, ist das Steckkom, das nur schwer zu entfernen ist. Zumeist ist das Profil, im Querschnitt gesehen, ein aus zwei Schenkeln bestehendes Winkelprofil, wobei zwischen den beiden Schenkeln ein stumpfer Winkel liegt, der Querschnitt kann aber auch gekrümmt oder mehrfach geknickt ausgebildet sein. Der Bereich im Stutzen ist daher für die Reinigung von Steckkom nicht gut zugänglich. Ein weiteres Problem, das bei starker Beanspruchung auftritt, ist die relativ hohe mechanische Belastung der oberen Kante jedes Stegs, die dem auftreffenden Siebgut besonders ausgesetzt ist.A problem of all generic, but also similar sieves in which, through the parts of the profiles that are not parallel to the screen surface, together with the webs creates a kind of downpipe or nozzle for each sieve opening is the Steckkom, which is difficult to remove. In most cases, the profile, seen in cross-section, consisting of two legs angle profile, with an obtuse angle between the two legs is, but the cross section may also be curved or bent several times. The area in the nozzle is therefore not easily accessible for the cleaning of Steckkom. Another problem that occurs under heavy use is the relatively high mechanical stress on the upper edge of each web, which is particularly exposed to the impacted screenings.
Eine nicht gattungsgemäße Abwandlung derartiger Siebe, bei der die Siebfläche in Form eines Zylindermantels ausgebildet ist, ist aus der
Eine andere Variante mit zylindrischer Siebfläche, die ebenfalls nicht gattungsgemäß ist, ist aus der

Die Erfindung hat die Aufgabe, ein Sieb des eingangs genannten Aufbaus auch für kleine Sieböffnungen zur Verfügung zu stellen, das die genannten Probleme nicht aufweist, ohne die Vorteile derartiger Siebe zu verlieren.The invention has the object to provide a screen of the structure mentioned above for small screen openings available that does not have the problems mentioned, without losing the benefits of such screens.
Erfindungsgemäß werden diese Ziele durch die im kennzeichnenden Teil des Anspruches 1 angeführten Merkmale erreicht.According to the invention, these objects are achieved by the features stated in the characterizing part of
Mit anderen Worten, es wird vorgesehen, dass entlang der oberen Kanten der Stege, die von der Aufgabeseite zur Überlaufseite orientiert sind, Leisten fest angeordnet sind, deren Breite größer ist als die Dicke der Stege. Zumindest einige der Leisten und/oder Stege sind mit den der Oberseite zugewandten Bereichen zumindest einiger Profile, die gebogenen oder geknickten Querschnitt aufweisen, verbunden, bevorzugt verschweißt, und fixieren so die Stege in den Profilen. Dazu ist es nicht notwendig, eine Verbindung zwischen jedem Profil und jeder Leiste zu schaffen. Durch die Leisten wird weiters der Querschnitt jedes Stutzens bzw. Fallrohrs für das Durchgangskorn in seinem obersten Bereich, in dem das Durchgangskom eintritt, verkleinert, sodass es kaum mehr zur Bildung von Steckkom kommt. Selbst wenn es dazu kommt, bleibt es doch im obersten Bereich stecken, wo es leicht zugänglich ist. Darüberhinaus ist die Leiste eine mechanische Verstärkung der oberen Kante jedes Steges und erhöht so die Lebensdauer des Siebes. Es ist dazu auszuführen, dass vorbekannte Verstärkungsleisten, wie sie verschiedentlich bei Sieben, die aus gelochten Platten bestehen, verwendet wurden, stets außerhalb des Bereiches der Sieböffnungen angeordnet sind.In other words, it is provided that along the upper edges of the webs, which are oriented from the task side to the overflow side, strips are fixed, the width of which is greater than the thickness of the webs. At least some of the strips and / or webs are connected, preferably welded, to the regions of at least some of the profiles which have a bent or bent cross-section and thus fix the webs in the profiles. It is not necessary to create a connection between each profile and each bar. Through the strips is further reduced the cross section of each nozzle or downpipe for the passage grain in its uppermost region in which the Durchgangsskom occurs, so that it hardly comes to the formation of Steckkom. Even if it comes to it, it remains stuck in the top area, where it is easily accessible. In addition, the bar is a mechanical reinforcement of the upper edge of each bar and thus increases the life of the sieve. It is to be understood that prior art reinforcing bars, as used variously in screens consisting of perforated plates, are always located outside the area of the screen openings.
Es soll zum Begriff "Siebfläche" ausgeführt werden, dass damit nicht nur die von den obersten Stellen der Stege bzw. Leisten und/oder Profile gebildete Fläche, die zumeist eben, gegebenenfalls aber auch zylindrisch gekrümmt sein kann, gemeint ist, sondern alle dazu parallelen Flächen, da der Begriff in der Beschreibung und den Ansprüchen nur als Referenz dient, um die Lage und Orientierung der Stege bzw. Profile anzugeben. Es könnte auch die Fläche herangezogen werden, die durch die Schwerpunkte der einzelnen Stege und Profile definiert wird, und die zur Fläche gemäß der ersten Definition in technisch ausreichendem Maß parallel verläuft. In Kenntnis der Erfindung ist es für den Fachmann ein Leichtes, für jeden Konstruktionsfall die Siebfläche auf günstigste Weise festzulegen.It should be made to the term "screen surface", so that not only the surface formed by the uppermost points of the webs or strips and / or profiles, which may be flat, but possibly also cylindrically curved is meant, but all parallel Surfaces, as the term in the description and the claims serves only as a reference to indicate the position and orientation of the webs or profiles. It could also be used the area, which is defined by the centers of gravity of the individual webs and profiles, and which runs parallel to the surface according to the first definition in a technically sufficient extent. In the knowledge of the invention, it is easy for the skilled person to set the screen area for each design case in the most favorable manner.
Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Dabei zeigt die einzige Figur eine perspektivische Ansicht eines kleinen Ausschnittes eines erfindungsgemäßen Siebes.The invention will be explained in more detail below with reference to the drawing. The single figure shows a perspective view of a small section of a screen according to the invention.
In der einzigen Figur ist ein Steg 1 mit einer aufgebrachten Leiste 2 in perspektivischer Ansicht rein schematisch dargestellt. Die Leiste 2 ist im dargestellten Ausführungsbeispiel mit quadratischem Querschnitt versehen, verläuft entlang der oberen Kante 7 des Steges 1 und ist mit einigen oder allen Profilen verbunden, beispielsweise verschweißt oder verklebt. Aus Gründen der Übersichtlichkeit wurde darauf verzichtet, die Verbindung, beispielsweise Schweißraupen oder Klebstoffflächen, darzustellen. Je nach zu erwartender Beanspruchung des Siebbelages und der daraus resultierenden Kräfte, die auf die Leiste 2 wirken, kann die obere Kante des Steges 1 und/oder die Seitenfläche des Ausschnittes 9 der Profile, beispielsweise durch Schleifen oder Fräsen, mit einer Kontur versehen sein, die dem Querschnitt der Leiste 2 angepasst ist und so die Kontaktfläche mit der Leiste vergrößert, doch üblicherweise reichen Punktschweißungen vollständig aus.In the single figure, a
Wie für den Fachmann auf dem Gebiete des Schweißwesens bekannt, sind bei Schweißverbindungen von nahezu eindimensionalen Gebilden entlang ihrer Länge aus thermischen Gründen eine Vielzahl von kurzen Schweißverbindungen günstiger als eine durchgehende Längsnaht, doch gehört dies zum allgemeinen technologischen Wissen des Schweißers und soll daher hier nur am Rande erwähnt werden.As is known to those skilled in the field of welding, welding joints of nearly one-dimensional structures along their length for thermal reasons, a plurality of short welded joints are cheaper than a continuous longitudinal seam, but this is part of the general technological knowledge of the welder and should therefore only on Be mentioned.
In der Figur sind auch die Schlitze 3 ersichtlich, die zur Steckverbindung der Stege 1 mit den Profilen 4 dienen. Der Form und Größe dieser Schlitze 3 entspricht dem Querschnitt der Profile 4, die ebenfalls Schlitze, nämlich Gegenschlitze 8 aufweisen. Das Sieb entsteht durch das parallele Anordnen einer entsprechenden Anzahl von Stegen 1 mit fluchtenden Schlitzen 3 und dem Einschieben einer entsprechenden Anzahl von Profilen 4 in die Schlitze 3 an den Stellen, an denen diese die Gegenschlitze 8 aufweisen. Fixiert wird diese Konstruktion einerseits durch Einbringen in einen entsprechend massiven Rahmen, andererseits durch die Verbindung der Leisten 2 mit den Profilen 4.In the figure, the slots 3 can be seen, which serve for the plug connection of the
Um für die Leisten 2 in oder nahe der Siebebene Platz zu machen und für die erwünschte Verkleinerung der Eingangsöffnung in den Stutzen, der durch die Stege und Profile entsteht, zu sorgen, weisen die siebparallelen Flächen 5 der Profile 4 Ausnehmungen 9 auf, die das Positionieren der Leisten 2 erlauben. Diese Ausnehmungen gehen, sich verjüngend, in die Gegenschlitze 8 über, entsprechend der Form und den Abmessungen der Leisten. Die obere Kante 7 der Stege, der Übergang zur Leiste 2, fällt dabei mit dem Übergang von der Ausnehmung 9 zum Gegenschlitz 8 im Profil 4 zusammen.To make room for the bars 2 in or near the level of the sieve and for the desired reduction of the entrance opening in the nozzle, by the webs and profiles arises to provide, the sieve-
Im dargestellten Ausführungsbeispiel ist die Siebfläche beispielsweise durch die Fläche definierbar, die durch die Vielzahl zueinander paralleler Oberkanten 6 der Leisten 2 gebildet wird. Es ist deutlich erkennbar, dass diese Definition, bei der es ja nur um die Orientierung der Ebene, aber nicht um ihre Höhenlage geht, auch durch die Flächen 5 erfolgen könnte.In the illustrated embodiment, the screen surface is defined for example by the surface, which is formed by the plurality of mutually parallel
Ohne Darstellung sei darauf hingewiesen, das es andere Möglichkeiten für die Querschnittsform der Leiste 2 gibt; beispielsweise den Kreisquerschnitt, aber auch den elliptischen Querschnitt, dessen Verwendung aber nur in Sonderfällen die Mehrkosten rechtfertigen wird; weiters möglich sind gleichschenkelige, beispielsweise rechtwinkelige Dreiecke, die Dreiecksform kann von dieser Form bis etwa zum gleichseitigen Dreieck variieren, spitzere Winkel zu beiden Seiten zu verwenden, ist aus mechanischen Gründen kaum angeraten; schließlich sind auch rechteckige Querschnitte, die T-förmig auf den Steg 1 aufgesetzt werden, möglich.Without illustration, it should be noted that there are other possibilities for the cross-sectional shape of the bar 2; for example, the circular cross-section, but also the elliptical cross-section, the use of which will only justify the additional costs in special cases; it is also possible to have isosceles, for example right-angled triangles, the triangular shape can vary from this shape to approximately the equilateral triangle, to use more acute angles on both sides, is hardly recommended for mechanical reasons; Finally, rectangular cross-sections that are T-shaped placed on the
Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsformen beschränkt, sondern kann verschiedentlich abgewandelt werden. So kann insbesondere das Verhältnis der Stärke des Steges 1 zur größten normal dazu verlaufenden Abmessung der Leiste 2 anders als dargestellt sein, es kann die Querschnittsform der Profile 4 eine andere sein als im dargestellten Ausführungsbeispiel (gebogen statt gekantet) und es kann die Anordnung (Winkellage) und der Abstand der Schlitze 3 in den Stegen 1 und/oder der Abstand der Gegenschlitze 8 in den Profilen anders als im dargestellten Ausführungsbeispiel gewählt werden.The invention is not limited to the illustrated and described embodiments, but can be modified variously. Thus, in particular, the ratio of the thickness of the
Durch Verzinken bzw. vergleichbare Tauchverfahren oder andere Auftragsverfahren, bei denen Kunststoff oder dergleichen flächig aufgebracht wird, erhält der Siebbelag eine Versiegelung der zahlreichen, wenn auch kleinen, Spalten, die sich aus dem Stecksystem ergeben, und verhindert somit auch das Hängenbleiben diverser Materialien wie Drähte, Fäden, Bändern und dergleichen. Dies bedeutet in der Praxis, dass die erfindungsgemäßen Siebe im Vergleich zu anderen Siebbelägen nur einen extrem geringen Reinigungsaufwand erfordern.By galvanizing or comparable dipping method or other application methods in which plastic or the like is applied flat, the screen lining receives a seal of numerous, albeit small, columns resulting from the plug-in system result, and thus also prevents the sticking of various materials such as wires, threads, tapes and the like. This means in practice that the screens according to the invention require only an extremely small amount of cleaning compared to other screen coverings.
Als Materialien für das Sieb und seine Beschichtung können alle im Stand der Technik bei derartigen Sieben üblichen Materialien verwendet werden, durch die erfindungsgemäßen Maßnahmen tritt diesbezüglich keine Änderung ein.As materials for the sieve and its coating, it is possible to use all materials customary in the state of the art in such sieves, and the measures according to the invention make no change in this regard.
Letztlich wesentlich ist, dass die größte Breite der Leisten 2 eine im Vergleich zur Stegdicke D deutlich größere Stärke B aufweisen, bevorzugt zumindest die Doppelte Stärke und besonders bevorzugt zumindest die Vierfache Stärke des Steges.Ultimately, it is essential that the largest width of the strips 2 have a significantly greater thickness B compared to the web thickness D, preferably at least twice the thickness and particularly preferably at least four times the thickness of the web.
Es soll noch darauf verwiesen werden, dass die Begriffe "parallel", "normal", "Kante", "Fläche", etc. stets im technischen Sin und nicht im strengen mathematischen Sinn zu verstehen sind. Weiters sind die Begriffe "oben", "unten", etc. im Hinblick auf die Zeichnung und den Siebvorgang zu verstehen.It should also be pointed out that the terms "parallel", "normal", "edge", "surface", etc. are always to be understood in the technical sense and not in the strict mathematical sense. Furthermore, the terms "top", "bottom", etc. with respect to the drawing and the screening process to understand.
