Description

Die Erfindung bezieht sich auf eine Walzenpresse mit einem Klapprahmen bestehend aus einem Rahmenunterteil, einem Rahmenobergurt und zwei seitlich angeordneten Kopfstücken, wobei zumindest ein Kopfstück mit einem daran angeordneten Teil des Rahmenobergurts eine Seitenklappe ausbildet, die am Rahmenunterteil aufklappbar angeordnet ist, und in dem Klapprahmen mindestens zwei nebeneinander positionierte Walzen platziert sind, die in einer Walzenentnahmestellung des Klapprahmens seitlich über die durch die aufgeklappte Seitenklappe ausgebildete Entnahmeöffnung aus dem Klapprahmen entnehmbar sind. Eine solche Walzenpresse ist beispielsweise aus der Broschüre "HRP Hydraulik Roller Press" der Fuller Corporation 7195 bekannt.
Walzenpressen werden für Brikettierungs-, Zerkleinerungs- und Kompaktierungsprozesse in Aufbereitungsanlagen eingesetzt. Über einen Zuführschacht werden Granulate zwischen zwei Walzen gefüllt. Die Walzen pressen das Granulat zusammen, zerkleinern es oder kompaktieren es. Walzenpressen ändern somit den Granulatzustand des Ausgangsmaterials, es werden beispielsweise Briketts geformt oder feine Stäube produziert. Dabei unterliegen die Walzen einem bedeutenden Verschleiß und müssen in bestimmten Abständen gewartet oder gewechselt werden. Solche Austausch- und Wartungsarbeiten, aber auch damit einhergehende Kontrollen ziehen Stillstandszeiten der Walzenpresse sowie der zugehörigen gesamten Aufbereitungsanlage nach sich.
The invention relates to a roller press with a folding frame consisting of a frame lower part, a frame top flange and two laterally arranged head pieces, wherein at least one head piece with a part of the Rahmenobergurts arranged thereon forms a side flap which is hinged to the frame base, and at least in the snap frame two juxtaposed rollers are placed, which are removable in a roll removal position of the folding frame laterally over the opening formed by the unfolded side flap removal opening from the folding frame. Such a roller press is known for example from the brochure "HRP Hydraulic Roller Press" Fuller Corporation 7195.
Roller presses are used for briquetting, crushing and compaction processes in processing plants. Granules are filled between two rolls via a feed chute. The rollers compress the granulate, crush it or compact it. Roller presses thus change the granular state of the starting material, for example briquettes are formed or fine dusts are produced. The rollers are subject to significant wear and must be serviced or replaced at certain intervals. Such replacement and maintenance work, but also associated controls pull down times of the roller press and the associated entire processing plant after.

In Bezug auf die Verfügbarkeit einer Aufbereitungsanlage stellt sich die Aufgabe, die Stillstandszeiten für Walzenpressen zu minimieren, da bei der Brikettierung, Zerkleinerung und Kompaktierung die Stillstandszeiten der Anlage im Wesentlichen durch den Austausch verschlissener Werkzeuge, d.h. Bandagen, Segmente etc., bestimmt werden. Für den Werkzeugwechsel müssen die Walzen, auf denen die Werkzeuge, angeordnet sind, aus der Maschine ausgebaut werden. Für Prozesse, in denen eine Walzenpresse in einer Schlüsselposition betrieben wird, können deshalb hohe Ausfallkosten durch die Stillstandszeiten beim Walzenwechsel entstehen. Gerade beim Betrieb mehrerer Maschinen in einem Prozess, beispielsweise bei der Heißbrikettierung, nehmen Wartungsarbeiten einen großen Zeitaufwand in Anspruch.With regard to the availability of a treatment plant, the task of minimizing standstill times for roll presses arises, since in the case of briquetting, comminution and compaction the downtimes of the plant are essentially replaced by the replacement of worn tools, i. Bandages, segments, etc., to be determined. For the tool change, the rollers on which the tools are arranged, must be removed from the machine. For processes in which a roll press is operated in a key position, therefore, high downtime costs can arise due to downtime during roll change. Especially when operating several machines in one process, for example in hot briquetting, maintenance work takes a great deal of time.

Um bei einer Walzenpresse eine Wartung oder Wechsel der Walzen auszuführen, sind unterschiedliche Öffnungsmechanismen bekannt. Hierbei werden sowohl Klapprahmen verwendet, welche einen schnellen Walzenwechsel zulassen, aber auch Rahmen, die für einen Walzenwechsel teilweise demontiert werden müssen. Bei der Auswahl eines geeigneten Maschinenrahmens für eine Walzenpresse müssen unterschiedliche Aspekte, von der Nutzung der Walzenpresse bis hin zum Aufstellungsort, berücksichtigt werden.In order to carry out a maintenance or change of the rollers in a roller press, different opening mechanisms are known. Here are both snap frames used, which allow a quick roll change, but also frames that must be partially disassembled for a roll change. When choosing a suitable machine frame for a roller press, different aspects, from the use of the roller press to the site of installation, have to be considered.

Bei der Auswahl eines Klapprahmens, der den Walzenwechsel nur zu einer Seite der Maschine zulässt, wird nur eine kleine Grundfläche für die Aufstellung der Anlage benötigt, da hierbei nur eine Seitenklappe aufgeklappt werden muss. Dabei kann diese Seitenklappe neben einem Kopfstück des Rahmens auch einen Teil des Rahmenobergurts umfassen, der fest mit dem Kopfstück verbundenen ist und beim Herausziehen der Walzen als Anschlag dient. Um jedoch die hintere Walze des Walzenpaares auswechseln oder warten zu können, muss bei einem solchen einseitigen Klapprahmen in jedem Fall auch die vordere Walze ausgebaut werden, was für den Fall des alleinigen Wechsels bzw. Kontrolle der hinteren Walze hinderlich ist. Von Vorteil ist jedoch, dass bei einem einseitigen Klapprahmen beide Walzen von einem Deckenkran gehoben und abtransportiert werden können, ohne dass der Zuführschacht der Walzenpresse abgebaut werden muss. (siehe Fig. 4)When selecting a folding frame, which allows roll change only to one side of the machine, only a small footprint is required for the installation of the system, as this only one side flap must be opened. In this case, this side flap next to a head piece of the frame also include a part of the Rahmenobergurts, which is firmly connected to the head piece and serves as a stop when pulling out the rollers. However, in order to replace or maintain the rear roller of the roller pair, in such a one-sided folding frame in any case, the front roller must be removed, which is a hindrance in the case of the sole change or control of the rear roller. The advantage, however, is that in a one-sided folding frame both rollers can be lifted and transported away by a ceiling crane without the feed shaft of the roller press must be dismantled. (see Fig. 4)

Bei einem Klapprahmen, der den Walzenwechsel zu beiden Seiten der Maschine zulässt, wird eine größere Grundfläche für die Anlage benötigt, da beide Seitenbereiche, d.h. Kopfstücke, des Rahmens aufgeklappt werden müssen. Ein solcher zweiseitiger Klapprahmen ermöglicht die bequeme, voneinander unabhängige Entnahme beider Walzen des Walzenpaares. Auch die Materialführungswände und die Zungen des Zuteilers brauchen nicht demontiert werden. Jedoch wird zum Abheben der Walzen auf beiden Seiten der Walzenpresse ein Deckenkran benötigt, da der Zuteiler und der Bunker über der Walzenpresse den Zugriff eines einzigen Deckenkrans auf beide Seiten des Klapprahmens verhindern. (siehe Fig. 5)With a cradle that allows for roll change on both sides of the machine, a larger footprint is required for the plant because both side areas, i. Head pieces, the frame must be unfolded. Such a two-sided snap frame allows convenient, independent removal of both rolls of the pair of rolls. Also, the material guide walls and the tongues of the meter need not be dismantled. However, to lift the rolls on both sides of the roll press, a ceiling crane is needed, as the hopper and bunker above the roll press prevent the access of a single overhead crane to both sides of the folding frame. (see Fig. 5)

Walzenrahmen, die nicht aufgeklappt werden können, sondern bei denen der obere Bereich der Maschine demontiert werden muss, weisen einen im Vergleich zu Klapprahmen deutlich erhöhten Montageaufwand auf. Zum Auswechseln der Walzen muss die Zuteileinheit abgebaut und über aufwändige Verschiebemechanismen entfernt werden. Neben der Arbeitsintensität ist bei solchen Rahmen auch der Zeitaufwand für den Wechsel oder Wartung der Walzen gegenüber Klapprahmen deutlich erhöht.Roller frames, which can not be unfolded, but in which the upper area of the machine must be dismantled, have a significantly increased compared to folding frame assembly work. To replace the rollers, the metering unit must be dismantled and removed by means of complicated displacement mechanisms. In addition to the labor intensity of such frames and the time required for the change or maintenance of the rollers against folding frame is significantly increased.

Es stellt sich daher für die vorliegende Erfindung die Aufgabe, einen Rahmen für Walzenpressen bereitzustellen, der die Nachteile der bisher im Stand der Technik bekannten Klapprahmen vermeidet und geringe Stillstandszeiten beim Walzenwechsel ermöglicht.It is therefore for the present invention, the task of providing a frame for roller presses, which avoids the disadvantages of the folding frame previously known in the art and allows low downtime when changing rolls.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der der Seitenklappe zugeordnete Teil des Rahmenobergurts mittels eines an dem zugehörigen Kopfstück angeordneten Gelenks relativ zum Kopfstück schwenkbar angeordnet ist.This object is achieved in that the side flap associated part of the Rahmenobergurts is arranged pivotably relative to the head piece by means of a arranged on the associated head joint.

Diese erfindungsgemäße Ausgestaltung der Walzenpresse ermöglicht durch eine vergrößerte Entnahmeöffnung des Klapprahmens eine einfache und bequeme Entnahme oder Wartung der Walzen. Der Einsatz dieses Klapprahmens realisiert so eine schnelle Walzendemontage bei einer einfachen Logistik und minimalem Demontageaufwand an der Gesamtanlage. Besonders vorteilhaft sind diese erfindungsgemäßen Walzenpressen für Anlagen, in denen mehrere Maschinen regelmäßig gewartet oder Walzen regeneriert werden müssen und sich Stillstandszeiten summieren.This inventive design of the roller press allows an enlarged removal opening of the snap frame easy and convenient removal or maintenance of the rollers. The use of this folding frame thus realizes a rapid roller dismantling with a simple logistics and minimal disassembly effort on the entire system. These roll presses according to the invention are particularly advantageous for installations in which several machines have to be regularly maintained or rolls have to be regenerated and downtimes accumulate.

Vorteilhafterweise können das aufgeklappte Kopfstück und der aufgeschwenkte Teil des Rahmenobergurts der Seitenklappe eine Verlängerung des Rahmenunterteils bilden und als belastbare Tragabschnitte zur Aufnahme der Walzen ausgestaltet sein. Dadurch wird ein seitliches Herausfahren beider Walzen auf die bevorzugt ebene Verlängerung und eine einfache Abnahme der Walzen, z.B. mittels eines Deckenkrans, ermöglicht. So kann auch die hintere Walze des Walzenpaares von den Tragabschnitten abgenommen und gegebenenfalls ersetzt werden, während die vordere Walze auf den Tragabschnitten verbleibt. Dabei ragen die belastbaren Tragabschnitte weit über die Grundfläche des geschlossenen Klapprahmens der Walzenpresse hinaus. Da dies jedoch nur beim Stillstand der Anlage der Fall ist, ist sowohl ein mögliches Hineinragen der Tragabschnitte in einen Fahrweg als auch eine allgemeine Gefährdung als unkritisch anzusehen.Advantageously, the unfolded head piece and the pivoted-on part of the frame top flange of the side flap can form an extension of the frame lower part and be configured as load-bearing support sections for receiving the rollers. This results in a lateral retraction of both rolls on the preferably flat extension and a simple decrease of the rolls, e.g. by means of a ceiling crane. Thus, the rear roller of the roller pair can be removed from the support sections and optionally replaced, while the front roller remains on the support sections. The load-bearing support sections protrude far beyond the base of the closed folding frame of the roller press. However, since this is the case only when the system is at a standstill, both a possible intrusion of the support sections into a track and a general hazard must be regarded as uncritical.

Eine Modifikation sieht vor, dass eine Walze als Loswalze ausgebildet ist und die Loswalze auf der Seite der Seitenklappe im Klapprahmen angeordnet ist. Da der Verschleiß der Loswalze statistisch größer als der Verschleiß der Festwalze ist, ermöglicht diese Anordnung einen insgesamt geringstmöglichen Montageaufwand und damit verbundene Stillstandszeiten.A modification provides that a roller is designed as a Loswalze and the Loswalze is arranged on the side of the side flap in the snap frame. Since the wear of the Loswalze is statistically greater than the wear of the hard roller, this arrangement allows a total of the lowest possible assembly costs and associated downtime.

Eine weitere Ausführungsform sieht vor, dass eine Walze als Loswalze ausgebildet ist und die Loswalze gegenüber der Seite der Seitenklappe im Klapprahmen angeordnet ist. Bei einer solchen Ausgestaltung muss die zum Andrücken der Loswalze in Richtung der Festwalze benötigte Andrückvorrichtung bei einem Austausch der Walzen nicht aus dem Klapprahmen herausgezogen werden und kann selbst bei einem Austausch oder einer Wartung der hinteren Walze im Klapprahmen verbleiben.A further embodiment provides that a roller is designed as a Loswalze and the Loswalze is arranged opposite the side of the side flap in the snap frame. In such an embodiment, the pressing device required to press the idler roller in the direction of the hard roller need not be pulled out of the folding frame when replacing the rollers and can remain in the folding frame even if the rear roller is replaced or serviced.

Zweckmäßigerweise kann der schwenkbare Teil des Rahmenobergurts sich über zwischen 25 % und 50 % des Rahmenobergurts erstrecken. Dies ermöglicht eine große Entnahmeöffnung bei nur geringem Überstand der Tragabschnitte gegenüber der Walzenpresse und trotzdem eine ausreichende Zugänglichkeit für die Abnahme der Walzen. Dabei kann der schwenkbare Teil des Rahmenobergurts zusätzlich um die Länge der Andrückeinrichtung vergrößert sein.Conveniently, the pivotable portion of the Rahmenobergurts extend over between 25% and 50% of the Rahmenobergurts. This allows a large removal opening with only slight projection of the support sections relative to the roller press and still sufficient accessibility for the removal of the rolls. In this case, the pivotable part of the Rahmenobergurts be additionally increased by the length of the pressing device.

Für eine gut abgestimmte Belastungsfähigkeit der Tragabschnitte bei guter Zugänglichkeit kann die Länge des schwenkbaren Teils des Rahmenobergurts mindestens der Höhe der seitlich angeordneten Kopfstücke entsprechen.For a well-balanced load capacity of the support sections with good accessibility, the length of the pivotable part of the Rahmenobergurts at least equal to the height of the laterally arranged head pieces.

Eine bevorzugte Variante sieht vor, dass auf dem Rahmenobergurt eine Zuführeinrichtung angeordnet ist und der schwenkbare Teil des Rahmenobergurts sich bis zur Zuführeinrichtung erstreckt. Die Ausgestaltung des gesamten Bereichs des Rahmenobergurts zwischen dem aufgeklappten Kopfstück und der Zuführeinrichtung, üblicherweise einem Trichter, als schwenkbarer Teil des Rahmenobergurts, ermöglicht eine maximale Entnahmeöffnung.A preferred variant provides that on the upper frame belt, a feed device is arranged and the pivotable part of the Rahmenobergurts extends to the feeder. The design of the entire region of the frame upper belt between the unfolded head piece and the feed device, usually a funnel, as a pivotable part of the frame upper belt, allows a maximum removal opening.

Eine günstige Ausbildung der erfindungsgemäßen Walzenpresse kann vorsehen, dass Mittel zum seitlichen Verfahren der Walzen vorgesehen sind. Hierdurch wird ein seitliches Herausfahren oder Herausziehen der Walzen aus dem abgedeckten Bereich des Klapprahmens auf das aufgeklappte Kopfstück oder den aufgeschwenkten Teil des Rahmenobergurts ermöglicht.A favorable design of the roller press according to the invention can provide that means for lateral movement of the rollers are provided. This allows a lateral retracting or pulling out of the rollers from the covered area of the folding frame on the unfolded head or the swung-part of the Rahmenobergurts.

Um ein einfaches seitliches Heraus- und Hineinfahren der Walzen zu ermöglichen, kann sich der seitliche Verfahrweg der Walzen bis auf die aufgeklappte Seitenklappe, bzw. den aufgeschwenkten Teil des Rahmenobergurts erstrecken.In order to allow a simple lateral out and in driving the rollers, the lateral travel of the rollers can extend to the unfolded side flap, or the swung-part of the Rahmenobergurts.

Fig. 1 zeigt eine schematische Darstellung einer Walzenpresse 1 in einer seitlichen Draufsicht. In dieser Figur, sowie in allen folgenden Figuren, sind dieselben Elemente mit denselben Bezugszeichen versehen. Die Walzenpresse 1 umfasst einen Klapprahmen 2 sowie zwei Walzen 3 und 4. Die Walzen 3 und 4 sind während des Betriebs im Inneren des Klapprahmens 2 angeordnet. Der Klapprahmen 2 besteht aus einem Rahmenunterteil 5, einem Rahmenobergurt 6 und zwei seitlich angeordneten Kopfstücken 7 und 8, wobei ein Kopfstück 7 den Rahmenunterteil 5 und den Rahmenobergurt 6 fest miteinander verbindet, während das zweite Kopfstück als eine am Rahmenunterteil 5 aufklappbar angeordnete Seitenklappe ausgebildet ist. Das Rahmenunterteil 5 weist nach unten vorstehende Aufstellungsabschnitte 9, zur Aufstellung der Walzenpresse 1 auf einer Umgebungsfläche, auf. Oberhalb der Walzen 3 und 4 sowie oberhalb des Rahmenobergurts 6 des Klapprahmens 2 ist eine trichterförmige Zuführeinrichtung 10 angeordnet. Die Zuführeinrichtung 10 hat zwei Öffnungen, wobei in der oberen Öffnung das zu verarbeitende Granulat eingefüllt wird, während es durch die untere Öffnung in einen Spalt zwischen die Walzen 3 und 4 gelangt.Fig. 1 shows a schematic representation of a roll press 1 in a lateral plan view. In this figure, as well as in all subsequent figures, the same elements are provided with the same reference numerals. The roller press 1 comprises a folding frame 2 and two rollers 3 and 4. The rollers 3 and 4 are arranged during operation inside the folding frame 2. The folding frame 2 consists of a frame lower part 5, a Rahmenobergurt 6 and two laterally arranged head pieces 7 and 8, wherein a head piece 7, the frame base 5 and the Rahmenobergurt 6 firmly together, while the second head piece is designed as a hinged to the frame base 5 side flap , The frame base 5 has downwardly projecting installation sections 9, for installation of the roll press 1 on an environmental surface on. Above the rollers 3 and 4 and above the Rahmenobergurts 6 of the folding frame 2, a funnel-shaped feeder 10 is arranged. The feeder 10 has two openings, wherein in the upper opening, the granules to be processed is filled while it passes through the lower opening in a gap between the rollers 3 and 4.

Während des Betriebs ist eine Walze, hier Walze 3, fest in dem Klapprahmen 2 angeordnet, während die zweite Walze (Walze 4) beweglich ist und durch eine Andrückeinrichtung 11 in Richtung der Festwalze gedrückt wird. Zwischen dem Kopfstück 8 der Seitenklappe und der Zuführeinrichtung 10 erstreckt sich ein mit dem Kopfstück 8 verbundener bewegbarer Teil 12 des Rahmenobergurts 6, so dass die Seitenklappe aus dem Kopfstück 8 und dem bewegbaren Teil 12 besteht. Das Kopfstück 8 der Seitenklappe ist mittels eines Gelenks 13 am Rahmenunterteil 5 befestigt und der bewegbare Teil 12 des Rahmenobergurts 6 ist wiederum mittels eines zweiten Gelenks 14 an dem Kopfstück 8 der Seitenklappe befestigt. Dabei sind die Gelenke 13 und 14 an sich gegenüberliegenden Enden des Kopfstücks 8 angeordnet. Der bewegbare Teil 12 des Rahmenobergurts 6 ist im Bereich der Zuführeinrichtung 10 mittels einer lösbaren Befestigungsvorrichtung 15 an dem nicht bewegbaren Abschnitt des Rahmenobergurts 6 befestigt. Das Rahmenunterteil 5, das feste Kopfstück 7 und der nicht bewegbare Abschnitt des Rahmenobergurts 6 bilden gemeinsam einen stabilen Abschnitt des Klapprahmens 2 in Form eines geöffneten C-Profils. Dabei trägt der feste Abschnitt des Rahmenobergurts 6 die Zuführeinrichtung 10 sowie weitere für die Zuführung von Granulat notwendigen Anlagenteile, beispielsweise, Materialzuführung, Bunker etc.During operation, a roller, here roller 3, is fixedly arranged in the folding frame 2, while the second roller (roller 4) is movable and is pressed by a pressing device 11 in the direction of the hard roller. Between the head piece 8 of the side flap and the feeder 10 extends a connected to the head piece 8 movable part 12 of the Rahmenobergurts 6, so that the side flap consists of the head piece 8 and the movable part 12. The head piece 8 of the side flap is fixed to the frame base 5 by means of a hinge 13, and the movable part 12 of the frame top piece 6 is in turn secured to the head piece 8 of the side flap by means of a second hinge 14. The joints 13 and 14 are arranged at opposite ends of the head piece 8. The movable part 12 of the Rahmenobergurts 6 is fixed in the region of the feeder 10 by means of a releasable fastening device 15 to the non-movable portion of the Rahmenobergurts 6. The frame bottom 5, the fixed head 7 and the non-movable portion of the Rahmenobergurts 6 together form a stable portion of the folding frame 2 in the form of an open C-profile. In this case, the fixed portion of the Rahmenobergurts 6 carries the feeder 10 and other necessary for the supply of granules equipment parts, for example, material supply, bunkers, etc.

Fig. 2 zeigt die erfindungsgemäße Walzenpresse 1 mit Klapprahmen 2 aus Fig. 1 in einem teilweise aufgeklappten Zustand. Hierbei ist die Seitenklappe um das Gelenk 13 in Richtung des eingezeichneten Pfeils geschwenkt worden. Das Kopfstück 8 der Seitenklappe stützt sich in dieser aufgeschwenkten Stellung mit einem Stützabschnitt 16 gegenüber der Umgebungsfläche ab, um gemeinsam mit dem Rahmenunterteil 5 eine Ebene zum seitlichen Verfahren der Walzen 3 und 4 auszubilden.Fig. 2 shows the roller press 1 according to the invention with folding frame 2 of FIG. 1 in a partially unfolded state. Here, the side flap has been pivoted about the hinge 13 in the direction of the arrow. The head piece 8 of the side flap is supported in this swung-open position with a support portion 16 relative to the surrounding area in order to form, together with the frame base 5, a plane for the lateral movement of the rollers 3 and 4.

In Fig. 3 ist der Klapprahmen 2 in einer vollständig aufgeschwenkten Stellung gezeigt. Dazu wurde der bewegbare Teil 12 des Rahmenobergurts 6 bei aufgeklapptem Kopfstück 8 um das Gelenk 14 in Pfeilrichtung geschwenkt. Das bewegbare Teil 12 stützt sich, ebenso wie das Kopfstück 8 der Seitenklappe, mit einem weiteren Stützabschnitt 17 auf der Umgebungsfläche ab und bildet zusammen mit dem Kopfstück 8 und dem Rahmenunterteil 5 eine gemeinsame Ebene zum seitlichen Verfahren der Walzen 3 und 4. Die Walzen 3 und 4 sind in dem in Fig. 3 gezeigten Montagezustand auf dem bewegbaren Teil 12 und dem Kopfstück 8 der Seitenklappe platziert.In Fig. 3, the folding frame 2 is shown in a fully swung-open position. For this purpose, the movable part 12 of the Rahmenobergurts 6 was pivoted with unfolded head piece 8 to the joint 14 in the arrow direction. The movable member 12 is supported, as well as the head piece 8 of the side flap, with another support portion 17 on the surrounding surface and forms, together with the head piece 8 and the frame base 5, a common plane for lateral movement of the rollers 3 and 4. The rollers 3 and 4 are placed in the mounting state shown in Fig. 3 on the movable part 12 and the head piece 8 of the side flap.

Im Folgenden wir die Funktionsweise des Klapprahmens 2 näher erläutert:In the following we explain the operation of the folding frame 2 in more detail:

Zur Entnahme der Walzen 3 und 4 aus dem Klapprahmen 2 kann bei einem anstehenden Austausch der Presswalzen oder notwendigen Wartungsarbeiten die Seitenklappe aus Kopfstück 8 und dem mit ihm verbundenen bewegbaren Teil 12 des Rahmenobergurts 6 geöffnet werden, wozu zunächst die Arretiervorrichtung 15 gelöst werden muss. Nach dem Lösen der Arretiervorrichtung 15 wird das Kopfstück 8 um das Gelenk 13 und der bewegbare Teil 12 um das Gelenk 14 geschwenkt, so dass sich eine große Entnahmeöffnung ausbildet. Das Kopfstück 8 und der bewegbare Teil 12 des Rahmenobergurts 6 stützen sich mit Stützabschnitten 16 und 17 auf einer Aufstellungsfläche ab und bilden gemeinsam mit dem Rahmenunterteil 5 eine Ebene zum seitlichen Verfahren der Walzen 3 und 4 aus. Um an die Walzen 3 und 4 zu gelangen, muss zunächst die Andrückeinrichtung 11 verschoben oder entfernt werden, beispielsweise durch einen Deckenkran von der Entnahmeöffnung abgehoben werden. Anschließend werden je nach Anforderung der Demontage oder Wartung die Loswalze 4 allein oder zusätzlich auch die Festwalze 3 aus ihrer Betriebsposition im Klapprahmen 2 seitlich in den Bereich der Entnahmeöffnung gezogen, mittels einer seitlichen Zugvorrichtung oder einer hydraulischen Verschiebeeinrichtung. Nach dem seitlichen Verfahren der Walzen 3 und 4 sind sie, platziert auf dem bewegbaren Teil 12 des Rahmenobergurts und dem Kopfstück 8 der Seitenklappe, gut zugänglich und mittels eines Deckenkrans oder anderer Hebeeinrichtungen vom Klapprahmen entfernbar, wie in Fig. 3 durch die nach oben gerichteten Pfeile angedeutet.To remove the rollers 3 and 4 from the folding frame 2, the side flap of the head piece 8 and its associated movable part 12 of the Rahmenobergurts 6 can be opened at a pending replacement of the press rolls or necessary maintenance, for which purpose first the locking device 15 must be solved. After releasing the locking device 15, the head piece 8 is pivoted about the joint 13 and the movable part 12 about the joint 14, so that a large discharge opening is formed. The head 8 and the movable part 12 of the Rahmenobergurts 6 are supported with support portions 16 and 17 on a mounting surface and form together with the frame base 5 a level for lateral movement of the rollers 3 and 4 from. To get to the rollers 3 and 4, the pressing device 11 must first be moved or removed, for example, be lifted by a ceiling crane from the removal opening. Subsequently, depending on the requirements of disassembly or maintenance, the idler roller 4 alone or in addition, the hard roller 3 is pulled laterally from its operating position in the folding frame 2 in the region of the removal opening, by means of a lateral pulling device or a hydraulic displacement device. After the lateral movement of the rollers 3 and 4, they are placed on the movable part 12 of the frame top and the head piece 8 of the side flap, easily accessible and removable by means of a ceiling crane or other lifting devices from the folding frame, as shown in Fig. 3 by the upward Arrows indicated.

Beim Aufklappen des Kopfstücks 8 und des bewegbaren Teils 12 der Seitenklappe bewegen sich diese Teile in einer zweidimensionalen Form jeweils um eine durch die Gelenke 13 und 14 verlaufende Achse, so dass die Gelenke 13 und 14 als Scharniere wirken. Dabei verlaufen die Achsen durch die Gelenke 13 und 14 im Wesentlichen parallel zueinander.When opening the head piece 8 and the movable part 12 of the side flap, these parts move in a two-dimensional shape each about an axis passing through the joints 13 and 14 axis, so that the joints 13 and 14 act as hinges. The axes run through the joints 13 and 14 substantially parallel to each other.

Fig. 4 zeigt eine im Stand der Technik bekannte Walzenpresse 1 mit einem einseitigen einteiligen Klappmechanismus. Zur Verdeutlichung werden nur die gegenüber der oben beschriebenen erfindungsgemäßen Ausgestaltung unterschiedlichen Merkmale beschrieben, wobei für gleiche Elemente dieselben Bezugszeichen verwendet werden. Auch bei diesen herkömmlichen Walzenpressen 1 besteht der Klapprahmen 2 aus einem Rahmenunterteil 5, einem Rahmenobergurt 6, einem seitlichen Kopfstück 7, die gemeinsam ein nicht bewegliches C-Profil bilden, und einer aufklappbaren Seitenklappe aus einem zweiten Kopfstück 8. Durch die bei aufgeklappter Seitenklappe sich ausbildende Entnahmeöffnung des Klapprahmens 2 können die Walzen 3 und 4 einzeln aus dem Klapprahmen entnommen werden. Falls nur die vordere Walze (hier Walze 3) ausgetauscht oder gewartet werden muss, ist dies in einfacher Weise möglich, da die vordere Walze auf die Seitenklappe aus dem Klapprahmen 2 hinausgezogen werden kann und dort gewartet oder zum Austausch abgehoben werden kann. Jedoch muss bei einer Wartung oder einem Austausch der hinteren Walze, in diesem Fall der verschleißanfälligeren Loswalze (Walze 4), zunächst die vordere Walze aus dem Klapprahmen 2 hinausgezogen und von der Seitenklappe abgehoben werden. Erst danach lässt sich die hintere Walze zur Wartung oder zum Austausch in den Bereich der Seitenklappe hinausziehen.Fig. 4 shows a known in the prior art roller press 1 with a one-sided one-piece folding mechanism. For clarification, only the features different from those described above according to the invention will be described, the same reference numerals being used for the same elements. Also in these conventional roller presses 1, the folding frame 2 consists of a frame base 5, a frame upper flange 6, a lateral head piece 7, which together form a non-movable C-profile, and a hinged side flap of a second head piece 8. The unfolded side flap forming removal opening of the folding frame 2, the rollers 3 and 4 can be removed individually from the folding frame. If only the front roller (here roller 3) has to be replaced or serviced, this is possible in a simple manner since the front roller can be pulled out onto the side flap out of the folding frame 2 and can be serviced there or lifted off for replacement. However, during maintenance or replacement of the rear roller, in this case the wear-prone loose roller (roller 4), first the front roller must be pulled out of the folding frame 2 and lifted off the side flap. Only then can the rear roller be pulled out to the side flap area for maintenance or replacement.

Bei der in Fig. 5 gezeigten Walzenpresse mit einem beidseitig zu öffnenden Klapprahmen 2, können die Walzen 3 und 4 unabhängig voneinander zu jeweils einer Seite des Klapprahmens 2 auf jeweils eine, aus den. Kopfstücken 8 bestehende, aufgeklappte Seitenklappe hinausgezogen werden, um von dort eine Wartung bzw. einen Austausch zu ermöglichen. Dies erfordert jedoch eine beidseitige Zugänglichkeit zu der Walzenpresse 1 sowie auf beiden Seiten Vorrichtungen zum Abheben der Walzen 3 und 4.In the roll press shown in Fig. 5 with a double-sided opening folding frame 2, the rollers 3 and 4 can independently to one side of each of the folding frame 2 on each one, from the. Heads 8 are pulled out existing, unfolded side flap to allow from there maintenance or replacement. However, this requires a two-sided accessibility to the roll press 1 and on both sides devices for lifting the rollers 3 and 4.
