  • Classic circular sieves are not suitable for a simple change of the sieve drum or the calibration cylinder and can therefore not be used for this type of specific calibration of the grains (e.g. for seed extraction).
  • DE-A-2 543 289 describes a screening drum for processing earth, debris or the like, which has a horizontal rotating cylinder mounted on rollers. This rotary cylinder is freely placed on drive rollers from above and is driven in the desired rotary motion by the drive of these rollers. An interchangeability of the screen drum is not provided in this known device. Rather, according to the teaching of DE-A-2 543 289, a screening machine is to be developed which can be adapted to a wide variety of screenings precisely without changing the screening drum.

  • the cleaning device consists of a cylindrical brush which, supported in a suitable manner, is supported from above by the action of gravity against the outer jacket of the screening drum. The rotary movement of the drum also causes the brush resting on the drum to rotate, thereby ensuring that the screen jacket of the rotating drum is continuously cleaned.
  • the invention has for its object to provide a simply constructed sorting cylinder that even by untrained personnel, without auxiliary tools and in the presence of a cleaning device for the outer jacket of the drum particularly easily and without loss of time in and out of the machine housing it can be expanded, so that only a particularly low expenditure of time and costs for installation and removal is required and also a particularly economical storage of the various basic elements is possible.

An accuracy of ⁇ 0.1 mm is required for the sieve opening during manufacture.
  • the rotary movement of the drum does not require any particular precision in manufacture.
  • a joint drive of the calibration cylinder and the cleaning device from one and the same drive ring has the further advantage that the distance between the cleaning device and the outer surface of the screening drum is always constant, which applies in part even to the smallest movements (such as vibrations, out-of-roundness, etc.) of the screening drum.

Description

Die Erfindung bezieht sich auf einen Sortierzylinder für Saatgut und anderes Korngut, mit einem liegenden, auf Rollen gelagerten und angetriebenen Kalibrierzylinder und einem den Kalibrierzylinder umschließenden, stationären Maschinengehäuse, das einen Guteinlauf für das zu sortierende Gut und Ableitmittel für die Fraktionen sowie eine abnehmbare Längsseitenwand aufweist.The invention relates to a sorting cylinder for seeds and other grain, with a horizontal calibration cylinder, which is mounted and driven on rollers and has a stationary machine housing surrounding the calibration cylinder, which has a material inlet for the material to be sorted and discharge means for the fractions as well as a detachable longitudinal side wall .

Solche Sortierzylinder, auf die sich die Erfindung bezieht, werden zur genauen Größentrennung von Körnergemischen eingesetzt. Bei Saatgut, z. B. Maiskörnern, müssen die Körner in ei nem sehr engen Größenbereich aussortiert werden. Einerseits ist die Größe des Saatgutes ein Qualitätskriterium, andererseits muß für die Sämaschine jedes einzelne Korn durch entsprechende Zuteilvorrichtungen aus der gesamten Kornmenge separiert und einzeln von der Maschine gesät werden. Je einheitlicher die Außenabmessungen der Körner sind, desto störungsfreier geht das Säen vor sich. Eine verhältnismäßig genaue Größenklassierung wünscht man aber auch bei anderem Saatgut, wie z. B. bei Weizen, Roggen, Reis, Sojabohnen, Grassamen usw. Ferner ist z. B. auch bei Kaffeebohnen die Größe ein Qualitätskriterium. Ein typisches Kennzeichen solcher Sortierzylinder liegt dabei in der Auswechselbarkeit des Arbeits- bzw. Kalibrierzylinders. Je nach den Anforderungen kann es dabei notwendig sein, ganz unterschiedliche Kalibrierzylinder einzusetzen: so kommt es häufig dazu, daß der Sortierzylinder täglich ausgewechselt werden muß.Such sorting cylinders, to which the invention relates, are used for the exact size separation of grain mixtures. For seeds, e.g. B. corn kernels, the kernels must be sorted out in a very narrow size range. On the one hand, the size of the seed is a quality criterion, on the other hand, each individual grain for the seeder must be separated from the total quantity of grain by appropriate allocation devices and sown individually by the machine. The more uniform the outer dimensions of the grains, the more trouble-free the sowing will be. A relatively accurate size classification is also desired for other seeds, such as. B. in wheat, rye, rice, soybeans, grass seeds, etc. Furthermore, for. B. the size of coffee beans is also a quality criterion. A typical characteristic of such sorting cylinders is the interchangeability of the working or calibration cylinder. Depending on the requirements, it may be necessary to use very different calibration cylinders: this often means that the sorting cylinder has to be replaced every day.

Klassische Rundsiebe sind für einen einfachen Wechsel der Siebtrommel bzw. des Kalibrierzylinders nicht geeignet und können deshalb für diese Art spezifischer Kalibrierung der Körner (wie z. B. bei Saatgutgewinnung) nicht eingesetzt werden.Classic circular sieves are not suitable for a simple change of the sieve drum or the calibration cylinder and can therefore not be used for this type of specific calibration of the grains (e.g. for seed extraction).

In der DE-A-2 543 289 ist eine Siebtrommel zur Aufbereitung von Erde, Schutt o. ä. beschrieben, die einen liegenden, auf Rollen gelagerten Drehzylinder aufweist. Dieser Drehzylinder ist frei von oben auf Antriebsrollen aufgesetzt und wird durch den Antrieb dieser Rollen in die gewünschte Drehbewegung versetzt. Eine Auswechselbarkeit der Siebtrommel ist bei dieser bekannten Vorrichtung nicht vorgesehen. Vielmehr soll nach der Lehre der DE-A-2 543 289 eine Siebmaschine entwickelt werden, die gerade ohne Wechsel der Siebtrommel an unterschiedlichstes Siebgut angepaßt werden kann. Auch eine Reinigungsvorrichtung für den Siebmantel derTrommel ist nicht vorhanden.DE-A-2 543 289 describes a screening drum for processing earth, debris or the like, which has a horizontal rotating cylinder mounted on rollers. This rotary cylinder is freely placed on drive rollers from above and is driven in the desired rotary motion by the drive of these rollers. An interchangeability of the screen drum is not provided in this known device. Rather, according to the teaching of DE-A-2 543 289, a screening machine is to be developed which can be adapted to a wide variety of screenings precisely without changing the screening drum. There is also no cleaning device for the drum drum screen.

Aus der GB-A-299 148 ist eine Drehtrommel mit einer Reinigungsvorrichtung für ihren Außenmantel bekannt, wobei hier allerdings die Gesamtvorrichtung zum Waschen von Kohle o. ä. eingesetzt wird. Ein leichtes Ausbauen der Drehtrommel ist jedoch ebenfalls nicht möglich, da die Halterungsgestelle für die beiden Enden der Längswelle der Reinigungsvorrichtung die Trommel in deren oberer Hälfte überspannen und sich auf dem die untere Trommelhälfte umschließenden Rahmen abstützen. Die Reinigungsvorrichtung besteht aus einer zylindrischen Bürste, die, in geeigneter Weise gelagert, sich von oben her durch Schwerkrafteinwirkung gegen den Außenmantel der Siebtrommel abstützt. Durch die Drehbewegung der Trommel wird die auf der Trommel aufliegende Bürste ebenfalls in Drehung versetzt und dadurch eine laufende Abreinigung des Siebmantels der Drehtrommel sichergestellt.From GB-A-299 148 a rotary drum with a cleaning device for its outer jacket is known, but here the entire device is used for washing coal or the like. However, easy removal of the rotating drum is also not possible, since the mounting frames for the two ends of the longitudinal shaft of the cleaning device span the drum in its upper half and are supported on the frame surrounding the lower half of the drum. The cleaning device consists of a cylindrical brush which, supported in a suitable manner, is supported from above by the action of gravity against the outer jacket of the screening drum. The rotary movement of the drum also causes the brush resting on the drum to rotate, thereby ensuring that the screen jacket of the rotating drum is continuously cleaned.

Bei einem bekannten Sortierzylinder der eingangs genannten Art, der im Handel angeboten wird, werden zum Zwecke der Möglichkeit eines schnellen Wechsels des Zylinders seitlich die Wellenstummel, die den Zylinder drehbeweglich lagern und antreiben, herausgezogen, so daß dann der Zylinder selbst durch eine wegnehmbare Längsseite des Gehäuses ein- und ausgebaut werden kann. Bei diesem bekannten Sortierzylinder ist eine Reinigungsvorrichtung jedoch ebenfalls nicht vorgesehen.In a known sorting cylinder of the type mentioned, which is on the market, for the purpose of a quick change of the cylinder laterally the stub shaft, which rotatably supports and drives the cylinder, is pulled out, so that the cylinder itself through a removable longitudinal side of the Housing can be installed and removed. However, a cleaning device is also not provided in this known sorting cylinder.

Das Vorhandensein von Reinigungsvorrichtungen erschwert und verlängert grundsätzlich den Vorgang beim Auswechseln einer Trommel.The presence of cleaning devices basically complicates and lengthens the process when changing a drum.

Ausgehend von dem aufgezeigten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen einfach aufgebauten Sortierzylinder vorzustellen, der selbst durch ungeschultes Personal, ohne Hilfswerkzeuge und bei Vorhandensein einer Reinigungsvorrichtung für den Außenmantel der Trommel besonders leicht und ohne Zeitverlust in das Maschinengehäuse ein- sowie aus ihm ausgebaut werden kann, so daß nur ein besonders geringer Aufwand von Zeit und Kosten für den Ein- und Ausbau erforderlich und auch eine besonders wirtschaftliche Lagerhaltung der verschiedenen Grundelemente möglich ist.Based on the prior art shown, the invention has for its object to provide a simply constructed sorting cylinder that even by untrained personnel, without auxiliary tools and in the presence of a cleaning device for the outer jacket of the drum particularly easily and without loss of time in and out of the machine housing it can be expanded, so that only a particularly low expenditure of time and costs for installation and removal is required and also a particularly economical storage of the various basic elements is possible.

Erfindungsgemäß wird dies bei einem Sortierzylinder der eingangs genannten Art dadurch erreicht, daß der Kalibrierzylinder auf vier Stützrollen nach oben frei abhebbar aufliegt und an seinem antriebsseitigen Ende einen mit einer Keilnut versehenen Antriebsring aufweist, der mit den seitlichen Führungsflächen einer mit entsprechendem Keilprofil und als Antriebsrad ausgebildeten Stützrolle durch Reibschluß in Eingriff steht, und daß eine Reinigungsvorrichtung für den Kalibrierzylinder vorgesehen ist, die vom Kalibrierzylinder aus angetrieben wird, relativ zum Kalibrierzylinder beweglich angeordnet ist und unter dem Einfluß der Schwerkraft auf ihrem Drehantrieb aufliegt. Der erfindungsgemäße Kalibrierzylinder ist auch bei Einsatz ungeübten Personales nicht nur besonders einfach und schnell ein- und ausbaubar, sondern er weist überdies bei verblüffend einfachem Aufbau eine absolut zuverlässige Funktionssicherheit des Gesamtgerätes auf. Insbesondere zeigt es sich auch, daß ein Überspringen des leichten Kalibrierzylinders in Form eines unerwünschten Herausspringens von den Stützrollen niemals auftrat. Durch die Ausbildung des Abtriebsringes mit einer Keilnut so, daß er mit den seitlichen Führungsflächen einer mit entsprechendem Keilprofil angetriebenen Stützrolle durch Reibschluß in Eingriff steht, kann der Kalibrierzylinder mühelos auf der nicht angetriebenen Endseite eingeschoben, auf den beiden Stützrollen dort abgelegt und dann auf der anderen Seite auf die Antriebsrolle bzw. die Stützrolle aufgelegt werden. Eine weitere Befestigung von irgendwelchen Antriebsmitteln entfällt ebenso wie ein Spannen von Schlaufen, Riemen oder Ketten. Nach dem Einschieben und Auflegen ist der Kalibrierzylinder bereits fertig montiert; er sitzt direkt auf seinem Lager. Bei Einschalten des Motors wird er angetrieben und ist gegen Längsbewegung durch die Keilflächen besonders gut gehalten. Die spezielle, erfindungsgemäße Anordnung bzw. Lagerung der Reinigungsvorrichtung läßt ebenfalls bei sehr einfachem Aufbau ein rasches Ein- und Ausbauen der Vorrichtung zu, so daß auch ein Wechsel des Sortierzylinders, der den Ausbau der Reinigungsvorrichtung voraussetzt, rasch und auch von Ungeübten durchgeführt werden kann. Reinigungsvorrichtung wie Sortierzylinder werden jeweils nur nach oben abgehoben und können über die freie Seitenwand des Gehäuses sogleich nach außen entfernt werden.According to the invention, this is achieved in a sorting cylinder of the type mentioned at the outset in that the calibration cylinder rests freely liftable on four support rollers and has at its drive-side end a drive ring provided with a keyway, which is designed with the lateral guide surfaces of a corresponding key profile and as a drive wheel Support roller is engaged by friction, and that a cleaning device for the calibration cylinder is provided, which is driven from the calibration cylinder, is movably arranged relative to the calibration cylinder and rests on its rotary drive under the influence of gravity. The calibration cylinder according to the invention is not only particularly easy and quick to install and remove even when inexperienced personnel are used, but it also has an absolutely reliable functional reliability of the overall device with an amazingly simple structure. In particular, it also shows that skipping the light calibration cylinder in the form of an unwanted forth jumping out of the support rollers never occurred. By designing the output ring with a keyway so that it engages with the lateral guide surfaces of a support roller driven with a corresponding key profile by frictional engagement, the calibration cylinder can be easily inserted on the non-driven end side, placed on the two support rollers there and then on the other Side are placed on the drive roller or the support roller. A further attachment of any drive means is omitted, as is tensioning of loops, belts or chains. After insertion and placement, the calibration cylinder is already fully assembled; he is sitting directly on his bed. When the motor is switched on, it is driven and is particularly well held against longitudinal movement by the wedge surfaces. The special arrangement and storage of the cleaning device according to the invention also allows the device to be installed and removed quickly with a very simple structure, so that a change of the sorting cylinder, which requires the cleaning device to be removed, can be carried out quickly and even by inexperienced users. Cleaning devices such as sorting cylinders are only lifted upwards and can be immediately removed to the outside via the free side wall of the housing.

Besonders vorteilhaft ist es, wenn je zwei Stützrollen auf beiden Endseiten des Kalibrierzylinders angeordnet sind.It is particularly advantageous if two support rollers are arranged on both end sides of the calibration cylinder.

Eine besonders vorteilhafte Ausführungsform des erfindungsgemäßen Kalibrierzylinders besteht auch darin, daß der Antriebsring seitlich eine kreiszylindrische Lauffläche und die zweite auf der Antriebsseite angeordnete Stützrolle ebenfalls eine kreiszylindrische Stützfläche aufweisen, wobei die Lauffläche auf der Stützrolle aufliegt.A particularly advantageous embodiment of the calibration cylinder according to the invention also consists in that the drive ring has a circular cylindrical running surface on the side and the second supporting roller arranged on the drive side likewise has a circular cylindrical supporting surface, the running surface resting on the supporting roller.

Vorzugsweise weist der Kalibrierzylinder auf seinem dem Antrieb gegenüberliegenden Ende im Bereich des Guteinlaufes einen Laufring auf, der auf zwei entsprechenden kreiszylindrischen Stützflächen der Stützrollen aufliegt. Man erhält weiterhin eine besondere Beruhigung des Laufes des Kalibrierzylinders, wenn das Antriebsrad mit einer weiteren Stützrolle auf der gegenüberliegenden Endseite des Kalibrierzylinders mit einer durchgehenden Antriebswelle starr verbunden ist: hierdurch läßt sich ein Antrieb des Kalibrierzylinders auf seinen beiden Endseiten erzielen, der für die Siebtrommel besonders schonend ist.The calibration cylinder preferably has, on its end opposite the drive in the area of the material inlet, a race which rests on two corresponding circular cylindrical support surfaces of the support rollers. You get a special calming of the running of the calibration cylinder if the drive wheel is rigidly connected to a further support roller on the opposite end side of the calibration cylinder with a continuous drive shaft: this enables the calibration cylinder to be driven on both end sides, which is particularly important for the sieve drum is gentle.

Es ist weiterhin sehr zweckmäßig, wenn der Guteinlauf in den Kalibrierzylinder hineinragt und der Kalibrierzylinder um einen etwas größeren Abstand als die Einragtiefe des Guteinlaufes in den Kalibrierzylinder vor der entsprechenden Endwand des Maschinengehäuses zum Zweck eines einfachen Ein- und Ausbaues des Kalibrierzylinders endet. Die als Antriebsräder ausgebildeten Stützrollen werden vorzugsweise aus Gummi und der Antriebsring sowie der Laufring aus einem verschleißfesten Kunststoff gebildet.It is also very expedient if the material inlet protrudes into the calibration cylinder and the calibration cylinder ends at a somewhat greater distance than the depth of insertion of the material inlet into the calibration cylinder in front of the corresponding end wall of the machine housing for the purpose of simple installation and removal of the calibration cylinder. The support rollers designed as drive wheels are preferably made of rubber and the drive ring and the race are made of a wear-resistant plastic.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Kalibrierzylinder sowie eine Reinigungsvorrichtung den Antriebsring als gemeinsames Antriebsglied und die Reinigungsvorrichtung ein mit entsprechendem Keilprofil versehenes Übertriebsrad aufweisen. Hierdurch erhält man nicht nur einen direkten Antrieb der Reinigungsvorrichtung, sondern überdies die Möglichkeit, auch die Reinigungsvorrichtung auf die gleiche Weise wie den Kalibrierzylinder einfach aus der Vorrichtung abzuheben bzw. in die Vorrichtung einzulegen, so daß tatsächlich beide Vorgänge mit je einem einzigen Handgriff durchgeführt werden können. Beide genannten Teile können von einer Auflagestelle angetrieben und geführt werden und erhalten entsprechend ihrem Gewicht eine größere oder kleinere Antriebskraft mitgeteilt. Die Keilform ist dabei ideal für den Antrieb, besonders bei der geschilderten Ausführungsform.A further advantageous embodiment of the invention is that the calibration cylinder and a cleaning device have the drive ring as a common drive member and the cleaning device has an overdrive wheel provided with a corresponding spline. This not only provides a direct drive for the cleaning device, but also gives the possibility of simply lifting the cleaning device out of the device or inserting it into the device in the same way as the calibration cylinder, so that both processes are actually carried out with a single movement can. Both parts mentioned can be driven and guided by a support point and receive a larger or smaller driving force according to their weight. The wedge shape is ideal for the drive, especially in the embodiment described.

Der keilförmige Eingriff und die keilförmige Abstützung an der genannten Stelle ergeben überdies nicht erwartete Vorteile für die ganze Maschine: der Kalibrierzylinder ist an sich mit sehr großer Präzision hergestellt, was die freien Durchgänge durch die Öffnungen der Siebtrommel anbelangt. Bei der Herstellung wird für die Sieböffnung eine Genauigkeit von ±0,1 mm verlangt. Die Drehbewegung der Trommel dagegen erfordert keine besondere Präzision in der Herstellung. Ein gemeinsames Antreiben des Kalibrierzylinders sowie der Reinigungsvorrichtung von ein und demselben Antriebsring aus bringt den weiteren Vorteil, daß der Abstand zwischen Reinigungsvorrichtung und Mantelfläche der Siebtrommel immer konstant ist, was zum Teil selbst bei Kleinstbewegungen (wie Vibrationen, Unrundheit usw.) der Siebtrommel gilt. Dies ergibt wiederum eine schonende Abreinigung des Siebtrommelmantels bzw. des entsprechenden Präzisionsgitterwerkes.The wedge-shaped engagement and the wedge-shaped support at the location mentioned also result in unexpected advantages for the whole machine: the calibration cylinder itself is manufactured with great precision as far as the free passages through the openings of the screening drum are concerned. An accuracy of ± 0.1 mm is required for the sieve opening during manufacture. The rotary movement of the drum, on the other hand, does not require any particular precision in manufacture. A joint drive of the calibration cylinder and the cleaning device from one and the same drive ring has the further advantage that the distance between the cleaning device and the outer surface of the screening drum is always constant, which applies in part even to the smallest movements (such as vibrations, out-of-roundness, etc.) of the screening drum. This in turn results in a gentle cleaning of the sieve drum shell or the corresponding precision latticework.

Es ist weiterhin von Vorteil, wenn die Reinigungsvorrichtung im wesentlichen radial zu dem Kalibrierzylinder in den Führungsmitteln verschiebbar ist, wobei die Bewegungsrichtung senkrecht oder leicht geneigt zu der Senkrechten liegt.It is also advantageous if the cleaning device can be displaced essentially radially to the calibration cylinder in the guide means, the direction of movement being perpendicular or slightly inclined to the vertical.

Es ist ebenfalls von Vorteil, wenn die Reinigungsvorrichtung an den beiden Endseiten in die Führungsmittel einschiebbare Gleitmittel aufweist, die, wiederum vorzugsweise, als Kugellager oder Wälzlager ausgebildet sind.It is also advantageous if the cleaning device has sliding means which can be inserted into the guide means at the two end sides and which, again preferably, are designed as ball bearings or roller bearings.

Eine weitere vorzugsweise Ausgestaltung besteht darin, daß die Reinigungsvorrichtung als rotierende Bürste oder auch als Schlägerwerk ausgebildet ist. Bevorzugt wird das Übertriebsrad der Reinigungsvorrichtung auf dieser drehfest gelagert und die Reinigungsvorrichtung ist relativ zum Kalibrierzylinder mittels am Maschinengehäuse befestigten Führungsmitteln beweglich geführt. Hieraus ergibt sich ohne weiteres, daß von Fall zu Fall eine Bürste oder ein Schlägerwerk als Reinigungsvorrichtung leicht eingelegt werden können.Another preferred embodiment is that the cleaning device is designed as a rotating brush or as a beater. The overdrive wheel of the cleaning device is preferably rotatably mounted on the latter and the cleaning device is movably guided relative to the calibration cylinder by means of guide means attached to the machine housing. From this it follows without further ado that a brush or a beater can be easily inserted as a cleaning device from case to case.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Kalibrierzylinder einen Antriebsring, einen Laufring und eine Paddelwelle aufweist, wobei die Siebtrommel, der Laufring, der Antriebsring und die Paddelwelle als eine ineinandersteckbare Baueinheit ausgebildet sind. Vorzugsweise wird dabei der Sortierzylinder als Baukasten ausgebildet, wobei eine Anzahl verschiedener Kalibrierzylinder oder eine Anzahl verschieden gelochter Siebtrommein die variablen Grundelemente bilden. Hierdurch ist es möglich, eine Anzahl verschiedener, aber fertig zusammengebauter bzw. vormontierter Kalibrierzylinder in Bereitschaft zu halten. Es können aber auch eine entsprechende Anzahl verschiedener Siebtrommeln ohne Ein- und Ausbau als Grundelemente bereitgehalten werden.A further advantageous embodiment of the invention consists in the fact that the calibration cylinder has a drive ring, a race and a paddle shaft, the sieve drum, the race, the drive ring and the paddle shaft being designed as an assembly which can be plugged into one another. The sorting cylinder is preferably designed as a modular system, with a number of different calibration cylinders or a number of differently perforated sieve drums forming the variable basic elements. This makes it possible to keep a number of different, but already assembled or pre-assembled calibration cylinders ready. However, a corresponding number of different sieve drums can also be kept as basic elements without installation and removal.

Eine weitere vorteilhafte Ausführung der Erfindung besteht darin, daß der Sortierzylinder als Baukasten-Einheit ausgebildet und als Reinigungsvorrichtung entweder eine rotierende Bürste oder ein Schlägerwerk eingesetzt sind.Another advantageous embodiment of the invention is that the sorting cylinder is designed as a modular unit and either a rotating brush or a beater mechanism is used as a cleaning device.

Es können aber auch mehrere Sortierzylinder übereinander angeordnet werden. Durch verschiedene Anzahl der Einläufe und Ausläufe können sogar die Verlustzeiten für Ein- und Ausbau

  • - für die bei der erfindungsgemäßen Lösung tatsächlich nur etwa zwei bis drei Minuten benötigt werden - wegfallen. Eine solche Anlage läßt sich somit durch entsprechende Schieber und Steuermittel automatisch einfach steuern, so daß z. B. nur noch bei Spezialprodukten der Kalibrierzylinder effektiv ausgewechselt werden muß.
However, several sorting cylinders can also be arranged one above the other. Due to the different number of inlets and outlets, even the lost times for installation and removal can be reduced
  • - For which only about two to three minutes are actually required in the solution according to the invention - are eliminated. Such a system can thus be easily controlled automatically by appropriate sliders and control means, so that, for. B. only needs to be replaced effectively with special products of the calibration cylinder.

Der Sortierzylinder gliedert sich im wesentlichen in vier Baugruppen, nämlich: in das Maschinengehäuse, den Kalibrierzylinder, die Reinigungsvorrichtung, sowie den Antrieb.The sorting cylinder is essentially divided into four subassemblies, namely: the machine housing, the calibration cylinder, the cleaning device and the drive.

Das allseitig geschlossene Maschinengehäuse 1 ruht mit Hilfe seiner beiden Stützen 2 und 3 auf dem Boden und weist an der einen Stirnseite einen Guteinlauf 4 und an der anderen Stirnseite einen Auslauf 5 für die Siebübergänge sowie auf seiner Unterseite zwei Auslauftrichter 6 und 7 für die Siebdurchgänge auf. Die Decke 8 des Maschinengehäuses 1 ist festgeschraubt und die beiden Längsseitenwände 41 und 42 sind durch einen Schnellverschluß 49 als Türen abnehmbar befestigt, um den Kalibrierzylinder 11 und, falls notwendig, die Reinigungsvorrichtung 45 leicht ein- und ausbauen sowie überwachen zu können. Der Guteinlauf 4 ist fest mit der einen Stirnwand 9 des Maschinengehäuses 1 verbunden, desgleichen der Auslauf 5 mit der anderen Stirnwand 10.The machine housing 1, which is closed on all sides, rests on the floor with the aid of its two supports 2 and 3 and has a good inlet 4 on one end face and an outlet 5 for the sieve transitions on the other end face and two outlet funnels 6 and 7 for the sieve passages on its underside . The ceiling 8 of the machine housing 1 is screwed tight and the two longitudinal side walls 41 and 42 are detachably fastened as doors by a quick-release fastener 49 in order to be able to easily install and remove and monitor the calibration cylinder 11 and, if necessary, the cleaning device 45. The material inlet 4 is firmly connected to one end wall 9 of the machine housing 1, as is the outlet 5 to the other end wall 10.

Der Kalibrierzylinder 11 besteht aus einem mit Sieblöchern 13 oder aus einer mit Drahtgitter (Fig. 6) versehenen Siebtrommel 12, auf deren bzw. dessen beiden Enden ein Laufring 14 bzw. ein Antriebsring 15 aus Kunststoff aufgesteckt sind. Eine Spannscheibe 16, die mit Hilfe ihrer Arme 17 und einer Spannmutter 18 gegen eine zentral im Inneren des Kalibrierzylinders 11 angeordnete Paddelwelle 19 mit schräggestellten Paddeln 20 gespannt ist, fixiert den Laufring 14 gegenüber der Siebtrommel 12. In gleicher Weise verbindet ein mit der Paddelwelle 19 verschweißter Spannstern 21 den Antriebsring 15 kraftschlüssig mit der Siebtrommel 12. Die Paddelwelle 19 ist also zum einen Fördermittel, indem sie mit Hilfe ihrer Paddel 20 für den Transport der Siebübergänge durch den Kalibrierzylinder 11 sorgt und zum anderen in Verbindung mit Spannstern 21 und Spannscheibe 16 Spannmittel zum Festhalten des Laufringes 14 sowie des Antriebsringes 15 auf der Siebtrommel 12, wodurch als ganzes der Kalibrierzylinder 11 gebildet wird. Dieser ist rollend auf vier Stützrollen (zwei achsgleich angeordneten Stützrollen 22 und 23 und zwei ebenfalls achsgleich angeordneten Antriebsrädern 24 und 25) abgestützt. Jede der beiden aus Kunststoff gefertigten Rollen 22 bzw. 23 ist auf einem an der Stirnwand 9 bzw. 10 befestigten Achsstumpf 44 (Fig. 8) drehbeweglich gelagert. Die mit dem Laufring 14 zusammenwirkenden Stützrollen 23 und 24 haben eine zylindrische Lauffläche, ebenso die Stützrolle 22, die mit einer zusätzlichen zylindrischen Stützfläche 15' des Antriebsringes 15 zusammenwirkt. Das Antriebsrad 25 ist mit einem Keilprofil mit seitlichen Führungsflächen 43 versehen, die in eine Keilnut 29 des Antriebsringes 15 eingreifen und so mit diesem reibschlüssig zusammenwirken (Fig. 8). Zwischen der Gummi-Lauffläche des Antriebsrades 24 und der zylindrischen Lauffläche des Laufringes 14 des Kalibrierzylinders 11 besteht ebenfalls kraftschlüssige Verbindung (Fig. 1).The calibration cylinder 11 consists of a sieve drum 13 provided with sieve holes 13 or of a wire mesh (FIG. 6), on whose or both ends a race 14 or a drive ring 15 made of plastic are attached. A tensioning disk 16, which is tensioned with the aid of its arms 17 and a tensioning nut 18 against a paddle shaft 19 arranged centrally in the interior of the calibration cylinder 11 with inclined paddles 20, fixes the race 14 with respect to the sieve drum 12. In the same way, one connects to the paddle shaft 19 welded tensioning star 21, the drive ring 15 non-positively with the sieve drum 12. The paddle shaft 19 is therefore on the one hand a means of conveyance by using its paddles 20 to transport the sieve transitions through the calibration cylinder 11 and on the other hand in connection with tensioning star 21 and tensioning disk 16 tensioning means to hold the race 14 and the drive ring 15 on the screening drum 12, whereby the calibration cylinder 11 is formed as a whole. This is supported in a rolling manner on four support rollers (two support rollers 22 and 23 arranged in the same axis and two drive wheels 24 and 25 also arranged in the same axis). Each of the two plastic rollers 22 and 23 is rotatably supported on an axle stub 44 (FIG. 8) attached to the end wall 9 and 10, respectively. The support rollers 23 and 24 cooperating with the race 14 have a cylindrical running surface, as does the support roller 22, which cooperates with an additional cylindrical support surface 15 'of the drive ring 15. The drive wheel 25 is provided with a spline profile with lateral guide surfaces 43 which engage in a keyway 29 of the drive ring 15 and thus cooperate with the latter in a frictionally locking manner (FIG. 8). There is also a non-positive connection between the rubber tread of the drive wheel 24 and the cylindrical tread of the race 14 of the calibration cylinder 11 (Fig. 1).

Die Reinigungsvorrichtung 45 ist als Schlägerwelle 30 mit blattförmigen Schlägern 31 ausgebildet (Fig. 3), die aus Kunststoff gefertigt und lösbar auf der Welle 30 befestigt sind. Die Schlägerwelle 30 ist in zwei Wälzlagern 32 gelagert (Fig. 4,7 und 9), die jeweils von einer U-förmigen Gleitbahn 33, die als Gleitkulisse wirkt, gleitbeweglich aufgenommen werden (Fig. 4 und 9). Die Kulisse 33 ist an der Stirnwand 9 bzw. 10 des Gehäuses mittels Schrauben 36 befestigt (Fig. 4). Mit Hilfe der gleichzeitig als Gleitmittel wirkenden Kugel- bzw. Wälzlager 32 in den radial zur Längsachse des Kalibrierzylinders 11 ausgerichteten Kulissen 33 ist die Schlägerwelle 30 queraxial und relativ zum Kalibrierzylinder 11 ortsveränderlich angeordnet. Auf der Schlägerwelle 30 sind ein Übertriebsrad 34 sowie ein Antriebsrad 35 aus Kunststoff oder Gummi drehfest angeordnet (Fig. 1, 2, 7 und 9), von denen das Antriebsrad 34 eine zylindrische Lauffläche aufweist und mit dem Laufring 14 des Kalibrierzylinders 11 kraftschlüssig in Verbindung steht (Fig. 1 und 7). Das Übertriebsrad 35 ist bezüglich seiner Lauffläche keilförmig ausgestaltet und greift mit dieser in die Keilnut 29 auf dem Antriebsring 15 des Kalibrierzylinders 11 ein, wodurch es kraftschlüssig mit diesem verbunden ist (Fig. 1 und 8).The cleaning device 45 is designed as a racket shaft 30 with leaf-shaped rackets 31 (FIG. 3), which are made of plastic and are detachably attached to the shaft 30. The racket shaft 30 is mounted in two roller bearings 32 (FIGS. 4, 7 and 9), which are each slidably received by a U-shaped slideway 33, which acts as a sliding link (FIGS. 4 and 9). The link 33 is fastened to the end wall 9 or 10 of the housing by means of screws 36 (FIG. 4). With the help of the ball or roller bearings 32, which simultaneously act as a lubricant, in the links 33, which are aligned radially to the longitudinal axis of the calibration cylinder 11, the racket shaft 30 is arranged transversely axially and in a positionally variable manner relative to the calibration cylinder 11. On the racket shaft 30, an overdrive wheel 34 and a drive wheel 35 made of plastic or rubber are arranged in a rotationally fixed manner (FIGS. 1, 2, 7 and 9), of which the drive wheel 34 has a cylindrical running surface and is non-positively connected to the race 14 of the calibration cylinder 11 stands (Fig. 1 and 7). The overdrive wheel 35 is wedge-shaped with respect to its tread and engages with it in the keyway 29 on the drive ring 15 of the calibration cylinder 11, whereby it is non-positively connected to it (FIGS. 1 and 8).

Für den Antrieb des Kalibrierzylinders 11 und der Schlägerwelle 30 ist ein Getriebemotor 37 vorgesehen (Fig. 1), der auf der Decke 8 des Maschinengehäuses 1 angeordnet ist und auf seiner Antriebswelle ein Kettenrad 38 drehfest trägt. Eine Kette 39 verbindet dieses mit einem Kettenrad 40, das drehfest auf der Welle 26 der Antriebsräder 24 und 25 befestigt ist. Das vom Getriebemotor 37 erzeugte Drehmoment wird über das Kettenradpaar 38 und 40 und die Kette 39 auf die Welle 26 und damit auf die Antriebsräder 24 und 25 übertragen. Diese treiben durch Reibschluß über den ihnen zugeordneten Laufring 14 bzw. Antriebsring 15 den Kalibrierzylinder 11 an. Der Laufring 14 und der Antriebsring 15 stehen außerdem in kraftschlüssiger Verbindung mit dem Übertriebsrad 34 bzw. dem Antriebsrad 35, so daß das Antriebsmoment nicht nur auf den Kalibrierzylinder 11, sondern beidseits auch gleichzeitig auf die Schlägerwelle 30 übertragen wird und diese in Drehbewegung versetzt. Das dem Sortierzylinder durch den Guteinlauf 4 zuströmende Korngut, beispielsweise Mais, fließt stirnseitig in das Innere des Kalibrierzylinders 11 hinein. Die mit dem Kalibrierzylinder 11 rotierenden Paddel 12 tauchen in das Gut ein und schieben es aufgrund ihrer Schrägstellung auf der Siebtrommet 12 axial vorwärts. Die großen, dikken Maiskörner werden auf diese Weise über die Siebtrommel 12 gefördert, durchströmen an deren Ende den Spannstern 21 und gelangen als Siebübergänge in den Auslauf 5 sowie in eine Abführleitung zur Verwendung als entsprechende Qualität des Saatgutes. Die kleinere Fraktion der Maiskörner fällt als Siebdurchgang durch die Sieblöcher 13 bzw. die spaltenförmigen Öffnungen zwischen einem entsprechend ausgebildeten Drahtgitter der Siebtrommel 12 hindurch in die Auslauftrichter 6 und 7, von wo sie durch deren Auslauföffnungen z. B. als Flachkörner die entsprechende flachere Qualität Saatgut bilden. Beim Mais ist es wegen der automatischen Sämaschinen besonders wichtig, daß kein übergro- ßers Korn im Saatgut vorliegt, da sonst die Lochungen bzw. die Verteilvorrichtung der Sämaschine blockiert würden. Während des Sortiervorganges läuft die Schlägerwelle 30 ständig um und ihre elastischen Schläger 31 schlagen auf die drehende Siebtrommel 12 des Kalibrierzylinders 11, wobei in den Kalibrieröffnungen 13 noch steckende Maiskörner bzw. Maiskornteile durch die Schläger zurückgedrückt oder zum Durchfallen gebracht werden. Die Siebtrommel 12 wird dadurch ständig gereinigt und ihre Kalibrieröffnungen 13 freigehalten. Da die Schläger 31 vorzugsweise aus Gummilappen oder Leder hergestellt sind, kommt der Schlag mehr einem kräftigen wiederholten Putzstreich gleich. Hierdurch ist auf jeden Fall vermieden, daß das hochpräzise Gittergewebe oder Lochblech beschädigt oder verformt werden könnte. Die im Dauereinsatz des Sortierzylinders unvermeidbare geringe Abnützung an den Laufflächen des Laufringes 14 bzw. des Antriebsringes 15 einerseits und der Stützrollen 22, 23 24 und 25 sowie der Übertriebs- bzw. Antriebsrollen 34 und 35 andererseits hat keinen nachteiligen Einfluß auf den Antrieb des Kalibrierzylinders 11 und der Schlägerwelle 30, weil der Kalibrierzylinder 11 durch die Schwerkraft mit seinem Laufring 14 bzw. Antriebsring 15 immer auf die Antriebsräder 24 und 25 sowie die Tragrollen 22 und 23 gedrückt wird: somit ist der erforderliche Kraft- bzw. Reibschluß stets sicher gewährleistet. Gleiches gilt im Bezug auf die Schlägerwelle 30, die in ihren Kulissen 33 relativ zum Kalibrierzylinder 11 beweglich ist, so daß sie bei Abnutzung zwischen dem Laufring 14 bzw. Antriebsring 15 und Übertriebsrad 34 bzw. Antriebsrad 35 unter dem Einfluß der Schwerkraft nachfahren kann, wodurch der nötige Kraftschluß auch hier aufrechterhalten bleibt. Nach längerer Betriebszeit können die Gummi- bzw. Kunststoffteile als Verschleißteile unschwer ersetzt werden.For driving the calibration cylinder 11 and the racket shaft 30, a geared motor 37 is provided (FIG. 1), which is arranged on the ceiling 8 of the machine housing 1 and carries a chain wheel 38 on its drive shaft in a rotationally fixed manner. A chain 39 connects this to a sprocket 40, which is non-rotatably attached to the shaft 26 of the drive wheels 24 and 25. The torque generated by the geared motor 37 is transmitted via the chain wheel pair 38 and 40 and the chain 39 to the shaft 26 and thus to the drive wheels 24 and 25. These drive the calibration cylinder 11 by frictional engagement via the race 14 or drive ring 15 assigned to them. The race 14 and the drive ring 15 are also in a non-positive connection with the overdrive wheel 34 and the drive wheel 35, so that the drive torque is not only transmitted to the calibration cylinder 11, but on both sides simultaneously to the racket shaft 30 and sets it in rotary motion. The grain material flowing into the sorting cylinder through the material inlet 4, for example maize, flows into the interior of the calibration cylinder 11 at the end. The paddles 12 rotating with the calibration cylinder 11 are immersed in the material and, owing to their inclined position on the sieve drum 12, push it axially forward. The large, thick corn kernels are conveyed in this way via the sieve drum 12, flow through the tensioning star 21 at the end thereof and reach the outlet 5 as a sieve transition and into a discharge line for use as the appropriate quality of the seed. The smaller fraction of the corn kernels falls as a sieve passage through the sieve holes 13 or the column-shaped openings between a correspondingly designed wire mesh of the sieve drum 12 into the outlet funnels 6 and 7, from where they pass through their outlet openings z. B. as flat grains form the corresponding flatter quality seeds. In the case of maize, it is particularly important because of the automatic seed drills that there is no oversize grain in the seed, since otherwise the perforations or the distribution device of the seed drill would be blocked. During the sorting process, the beater shaft 30 constantly rotates and its elastic beaters 31 hit the rotating sieve drum 12 of the calibration cylinder 11, with corn kernels or corn kernel parts still stuck in the calibration openings 13 being pushed back by the beaters or causing them to fall through. The sieve drum 12 is thereby constantly cleaned and its calibration openings 13 are kept free. Since the bat 31 is preferably made of rubber cloth or leather, the blow is more like a vigorous repeated brushing stroke. In this way, it is avoided in any case that the high-precision mesh or perforated plate could be damaged or deformed. The unavoidable wear on the running surfaces of the race 14 or the drive ring 15 on the one hand and the support rollers 22, 23 24 and 25 and the overdrive or drive rollers 34 and 35 on the other hand, which is unavoidable in the continuous use of the sorting cylinder, has no adverse effect on the drive of the calibration cylinder 11 and the racket shaft 30 because the calibration cylinder 11 is always pressed by gravity with its race 14 or drive ring 15 onto the drive wheels 24 and 25 as well as the support rollers 22 and 23: the required force or frictional engagement is thus always guaranteed. The same applies in relation to the racket shaft 30, which is movable in its links 33 relative to the calibration cylinder 11, so that it can follow under the influence of gravity when worn between the race 14 or drive ring 15 and overdrive wheel 34 or drive wheel 35, thereby the necessary adhesion is also maintained here. After a long period of operation, the rubber or plastic parts can easily be replaced as wearing parts.

Muß der Kalibrierzylinder 11 oder die Schlägerwelle 30 ausgebaut werden, etwa für einen Produktwechsel, und die Siebtrommel 12 durch eine mit anderer Sieblochung ersetzt werden, so wird durch Lösen der besagten Schnellverschlüsse 49 eine Längsseitenwand des Maschinengehäuses 1 einfach abgenommen (Fig. 5 und 6). Die Schlägerwelle 30 und der Kalibrierzylinder 11 sind damit leicht zugänglich. Es kann nunmehr die Reinigungsvorrichtung 45 leicht aus den U-förmigen Kulissen 33 der Führungsmittel 48 und durch entsprechendes queraxiales Bewegen aus dem Maschinengehäuse 1 herausgenommen werden (Fig. 5). Nachdem die Schlägerwelle 30 demontiert ist, kann auch gleich ganz einfach der Kalibrierzylinder 11 ausgebaut werden. Dies geschieht durch geringfügiges Anheben des Kalibrierzylinders 11 von seinen Stützrollen 22 und 25 sowie durch anschließendes axiales und queraxiales Bewegen desselben (Fig. 6).If the calibration cylinder 11 or the beater shaft 30 has to be removed, for example for a product change, and the sieve drum 12 has to be replaced by one with a different perforation, a long side wall of the machine housing 1 is simply removed by loosening the quick-release fasteners 49 (FIGS. 5 and 6). . The racket shaft 30 and the calibration cylinder 11 are thus easily accessible. The cleaning device 45 can now easily be removed from the U-shaped link 33 of the guide means 48 and by corresponding transverse axial movement from the machine housing 1 (FIG. 5). After the racket shaft 30 has been dismantled, the calibration cylinder 11 can also be easily removed. This is done by slightly lifting the calibration cylinder 11 from its support roll 22 and 25 and by subsequent axial and transverse axial movement of the same (Fig. 6).

Wie in Fig. 5 dargestellt, kann der Kalibrierzylinder 11 unschwer ohne Hilfswerkzeuge ein- und ausgebaut werden, indem er von der Auflagestelle etwa um die Höhe der Keilnut 29 des Antriebsringes 15 abgehoben wird, sodann um eine Länge A (vgl. Fig. 2) seitlich vom Guteinlauf 4 weggezogen und anschließend durch eine queraxiale Bewegung aus dem Maschinengehäuse 1 entfernt wird. In den Fig. 7 und 8 ist ein Zusammenbau der bewegten Grundelemente in bezug auf Antrieb und Übertrieb schematisch dargestellt, wobei das Maschinengehäuse 1 zur übersichtlicheren Darstellung weggelassen ist. Für die Bezugzeichen wird auf die vorangegangene Beschreibung Bezug genommen.As shown in FIG. 5, the calibration cylinder 11 can be easily installed and removed without auxiliary tools by lifting it from the support point by approximately the height of the keyway 29 of the drive ring 15, then by a length A (see FIG. 2). laterally pulled away from the material inlet 4 and then removed from the machine housing 1 by a transverse axial movement. 7 and 8, an assembly of the moving basic elements with respect to drive and overdrive is shown schematically, the machine housing 1 being omitted for clarity. For the reference symbols, reference is made to the preceding description.

Fig. 9 zeigt die Reinigungsvorrichtung 45 ebenfalls in schematischer Darstellung, wobei insbesondere die Beweglichkeit innerhalb der Kulissenführungen 33 ersichtlich ist.FIG. 9 also shows the cleaning device 45 in a schematic illustration, the mobility within the link guides 33 in particular being evident.

Aus der Darstellung nach Fig. 3 ist ersichtlich, wie die beiden Längsseitenwände 41 und 42 nach Öffnen der Schnellverschlüsse 49 leicht aus der unteren Halterung 50 gehoben werden können. Für die Praxis ist es von großem Vorteil, daß beide Seiten (d. h. beide Längsseitenwände 41 und 42) geöffnet werden können, damit ein Entfernen je nach der gegebenen örtlichen Situation bzw. nach den Bedienungsmöglichkeiten durchgeführt werden kann. Zu diesem Zwecke können Führungsmittel 48 links und rechts, also doppelt, vorgesehen werden, wie dies z. B. in Fig. 3 dargestellt ist. Die Reinigungsvorrichtung 45, z. B. in Form von Bürsten 46 oder eines Schlägerwerkes 47, könnte aber auch direkt vom Antriebsmotor 37 angetrieben werden (in den Figuren nicht dargestellt). Bei einem festen Einbau einer entsprechenden Reinigungsvorrichtung 45 muß dafür gesorgt werden, daß trotzdem ein ungehinderter Ein- und Ausbau des Kalibrierzylinders 11 möglich ist. Gegenüber dem Zentrum des Kalibrierzylinders 11 müssen dabei die Stützrolle 22, das Antriebsrad 25 sowie die Reinigungsvorrichtung 45 einen Winkel von weniger als 180° einnehmen bzw. der freie Raum für den Ausbau des Kalibrierzylinders muß mehr als 180° geöffnet sein. Die Ausläufe 6 und 7 können, wie in Fig. 1 dargestellt, nach unten oder aber auch stark auf eine Längsseite geführt sein, so daß dann, wenn mehrere Maschinen übereinander gestellt werden müssen, der untere Auslauftrichter 6 und 7 jeweils in der oberen rechten Ecke (nach der Darstellung von Fig. 3) angeordnet ist. In diesem Fall kann die linke Längsseitenwand geöffnet werden, was für die Lösung, wie sie in Fig. 3 dargestellt ist, keinerlei Nachteile bringt, da die Reinigungsvorrichtung 45 wie auch der Kalibrierzylinder 11 in diesem Fall auf die gleiche Seite frei heraushebbar sind.3 shows how the two longitudinal side walls 41 and 42 can be easily lifted out of the lower holder 50 after the quick-release fasteners 49 have been opened. In practice, it is of great advantage that both sides (i.e. both longitudinal side walls 41 and 42) can be opened so that removal can be carried out depending on the given local situation or the operating options. For this purpose, guide means 48 can be provided on the left and right, ie twice, as z. B. is shown in Fig. 3. The cleaning device 45, e.g. B. in the form of brushes 46 or a beater 47, but could also be driven directly by the drive motor 37 (not shown in the figures). With a fixed installation of a corresponding cleaning device 45, it must be ensured that an unimpeded installation and removal of the calibration cylinder 11 is still possible. Compared to the center of the calibration cylinder 11, the support roller 22, the drive wheel 25 and the cleaning device 45 must be at an angle of less than 180 ° or the free space for the expansion of the calibration cylinder must be open more than 180 °. The outlets 6 and 7 can, as shown in Fig. 1, be led down or also strongly on one long side, so that when several machines have to be placed one above the other, the lower outlet funnels 6 and 7 are each in the upper right corner (according to the representation of Fig. 3) is arranged. In this case, the left longitudinal side wall can be opened, which has no disadvantages for the solution as shown in FIG. 3, since the cleaning device 45 and the calibration cylinder 11 can be freely lifted out on the same side in this case.

Bei der in Fig. 10 gezeigten diagrammatischen Prinzipdarstellung eines eigentlichen Kalibriervorganges innerhalb einer Saatgutanlage tritt das gesamte Produkt oben in die vier Sortierzylinder 101 ein und drängt die gröbste Fraktion aus, die als Abfall S einer weiteren Verarbeitung zugeführt wird. Für eine große Leistung sind (bei der Darstellung nach Fig. 10) vier identische Sortierzylinder 101 parallel zueinander eingesetzt. Der Durchfall dieser Sortierzylinder 101 wird so dann zur Kalibrierung auf eine weitere Sortierzylindergruppe 102 geführt, bei der jeder Sortierzylinder je zwei grobe und eine feine Fraktion zu einer weiteren nachgeschalteten Kalibrierung erzeugt. Die beiden Grobfraktionen sowie die Feinfraktion werden den weiteren Zylindern 103 bzw. 104 bzw. 105 zur weiteren Kalibrierung zugeführt. Für die Längensortierung werden die Feinfraktionen der Sortierzylinder 103, 104 und 105 auf Trieure 106, 107 und 108 geführt. Die Endprodukte werden in den entsprechenden Vorratszellen (ohne Bezugszeichen in Fig. 10) gelagert, wovon sie bei Bedarf entnommen werden können.In the diagrammatic basic illustration of an actual calibration process within a seed plant shown in FIG. 10, the entire product enters the four sorting cylinders 101 at the top and expels the coarsest fraction, which is fed as waste S to further processing. For a high performance (in the illustration according to FIG. 10), four identical sorting cylinders 101 are used in parallel with one another. The diarrhea of these sorting cylinders 101 is then passed for calibration to a further sorting cylinder group 102, in which each sorting cylinder generates two coarse and one fine fraction for a further downstream calibration. The two coarse fractions and the fine fraction are fed to the further cylinders 103, 104 and 105 for further calibration. For the length sorting, the fine fractions of the sorting cylinders 103, 104 and 105 are fed onto drives 106, 107 and 108. The end products are stored in the corresponding storage cells (without reference numerals in FIG. 10), from which they can be removed if required.

Die Kalibrierung mit den Sortierzylindern stellt die wichtigste Funktion für die richtige Größenaufteilung von körnigen Produkten dar und findet in dafür speziell gebauten Anlagen statt.Calibration with the sorting cylinders is the most important function for the correct size distribution of granular products and takes place in specially built systems.
