Description

Die Erfindung betrifft eine Presse der Gattung, wie beschrieben im Oberbegriff des ersten Patentanspruchs.The invention relates to a press of the type as described in the preamble of the first claim.

Eine Presse dieser Gattung ist bekannt aus der DE-PS 27 24 060. Pressen nach diesem Prinzip wurden weiter entwickelt, um einen höheren Ausstoß zu erreichen. Zu diesem Zweck mußte die Preßstrecke verlängert werden bei gleichbleibender Aushärtungszeit der Bindemittel. Eine Verlängerung der Preßstrecke bedeutet bei Rotationspressen, d.h. bei Pressen mit einer rotierenden Trommel, bei denen die Verpressung zwischen dem äußeren Trommelmantel und einem endlosen, die Trommel teilweise umschlingenden, unter Zugspannung stehenden Stahlband erfolgt, eine Vergrößerung des Trommeldurchmessers. Die neuesten Pressen dieser Art weisen Trommeln mit einem Durchmesser von 5 m auf, bei einer Ballenlänge von ca. 3 m und einem Trommelgewicht von ca. 110 t.A press of this type is known from DE-PS 27 24 060. Presses based on this principle have been further developed in order to achieve a higher output. For this purpose, the press section had to be extended while the binder hardening time remained the same. An extension of the press section means in the case of rotary presses, i.e. in the case of presses with a rotating drum, in which the compression takes place between the outer drum shell and an endless steel belt, which is partially wrapped around the drum and is under tension, the drum diameter increases. The latest presses of this type have drums with a diameter of 5 m, a bale length of approx. 3 m and a drum weight of approx. 110 t.

Nachteilig bei derart großen Pressen ist, daß bedingt durch erforderliche Montage- und Fertigungstoleranzen an der Presse beim Anfahren und beim Leerfahren Schäden an dem endlosen Stahlband, dem äußeren Trommelmantel und an den Andrückwalzen entstehen, weil sich diese Maschinenteile ohne zu verpressendes Material metallisch berühren.A disadvantage of such large presses is that due to the required assembly and manufacturing tolerances on the press when starting up and when empty, damage to the endless steel belt, the outer drum jacket and the pressure rollers occurs because these machine parts touch without metal to be pressed.

Auf der anderen Seite wird durch die Vergrößerung des Trommeldurchmessers von 3.000 auf 5.000 mm ermöglicht, auf eine kontinuierliche Weise eine Bahn von 3 mm Dicke mit einem Ausstoß (in Abhängigkeit von der Bahndicke) bis zu ca. 40 m/min zu fahren, was im Mittel eine Steigerung von über 200 % bedeutet.On the other hand, by increasing the drum diameter from 3,000 to 5,000 mm, it is possible to run a web of 3 mm thickness with an output (depending on the web thickness) up to approx. 40 m / min in a continuous manner, which in the Medium means an increase of over 200%.

Es ist die Aufgabe der Erfindung, eine kontinuierliche Rotationspresse der Gattung, wie beschrieben im Oberbegriff des Patentanspruchs 1, so weiter zu bilden, daß damit ein hoher kontinuierlicher Ausstoß der Presse sichergestellt wird, ohne daß beim Anfahren der Presse oder am Ende eines Preßvorganges, wenn sich kein Material in der Presse befindet, Schäden an dem Preßtrommelmantel, dem endlosen Stahlband oder an den Andrückwalzen auftreten.It is the object of the invention to develop a continuous rotary press of the type as described in the preamble of claim 1 so that it ensures a high continuous output of the press without having to start the press or at the end of a pressing process if there is no material in the press, damage to the press drum jacket, the endless steel belt or the pressure rollers.

Mit der Presse sollen auch dünnste Span- oder Faserplattenbahnen ab einem Millimeter mit äußerst geringen Dickentoleranzen, hohen spezifischen Festigkeiten und guten Biege- und Schlagfestigkeiten hergestellt werden können.The press should also be able to produce the thinnest particle or fiberboard webs from one millimeter with extremely low thickness tolerances, high specific strengths and good bending and impact strength.

Die Aufgabe wird durch die in dem kennzeichnenden Teil des ersten Patentanspruchs beanspruchten Merkmale gelöst.The object is achieved by the features claimed in the characterizing part of the first claim.

Die Unteransprüche stellen vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung dar.The subclaims represent advantageous refinements and developments of the invention.

Durch die radiale Verstellbarkeit der Achse der Preßtrommel gegenüber den Achsen der Umlenk- und Andrückwalzen wird eine Fixierung der Achse der sehr schweren Preßtrommel an einem Punkt sichergestellt. Der somit einmal eingestellte Spalt (Abstand) zwischen dem Trommelmantel und den Andrück- und Umlenkwalzen wird exakt eingehalten, wodurch eine Beschädigung des Stahldruckbandes und der Walzen- und Trommeloberflächen vermieden wird, weil Montagetoleranzen und Spiele der einzelnen Bauteile der Presse wirkungsvoll ausgeschaltet werden.The radial adjustability of the axis of the press drum relative to the axes of the deflection and pressure rollers ensures that the axis of the very heavy press drum is fixed at one point. The gap (distance) thus set between the drum jacket and the pressure and deflection rollers is adhered to exactly, which prevents damage to the steel printing belt and the roller and drum surfaces, because assembly tolerances and play of the individual components of the press are effectively eliminated.

Der Vorteil der erfindungsgemäßen Presse wird sehr deutlich bei der Herstellung von Bahnen von beispielsweise einer Dicke von 1 mm, also Bahndicken, die innerhalb des Montagespiels der Bauteile der Presse liegen.The advantage of the press according to the invention is very clear in the production of webs of, for example, a thickness of 1 mm, that is to say web thicknesses which lie within the assembly play of the components of the press.

Durch die definitive radiale Einstellung der großen Trommelachse läßt sich die große Trommel exakt positionieren, so daß trotz montagebedingter Toleranzen der Bauteile (Ständer und Lager), die bis zu 1,5 mm betragen können, eine exakte Dickeneinstellung der herzustellenden Bahn erreicht wird.Due to the definitive radial setting of the large drum axis, the large drum can be positioned exactly, so that despite the assembly-related tolerances of the components (stands and bearings), which can be up to 1.5 mm, an exact thickness adjustment of the web to be produced is achieved.

Gemäß Anspruch 1 erfolgt die radiale Verstellung der Achse der Preßtrommel gegenüber den Achsen der Umlenk- und Andrückwalzen mittels auf den Achsenden angeordneten Zusatzlagern, an die ein Hydraulikzylinder, der am Ständer abgestützt ist, angreift. Durch diese Maßnahme wird das Spiel in den Ständerteilen und in den Lagern der Achstrommel entsprechend der Druckbeaufschlagung der beiden jeweils am Achsende angeordneten Hydraulikzylinder aufgehoben. Die große Preßtrommel ist somit exakt zu den Andrückwalzen positionierbar.According to claim 1, the radial adjustment of the axis of the press drum relative to the axes of the deflection and pressure rollers takes place by means of additional bearings arranged on the axle ends, to which a hydraulic cylinder which is supported on the stand acts. As a result of this measure, the play in the stand parts and in the bearings of the axle drum is eliminated in accordance with the pressurization of the two hydraulic cylinders arranged at the axle end. The large press drum can thus be positioned exactly in relation to the pressure rollers.

Die in Patentanspruch 2 beschriebene Ausführungsform sieht eine Verstelleinrichtung vor mit einem Hydraulikzylinder und einem Hebelarm, so daß die Verstellung der Achse um einen am Ständer angeorndeten Festpunkt erfolgt. Eine derartige Verstelleinrichtung ist kostengünstiger in der Herstellung und im Betrieb.The embodiment described in claim 2 provides an adjusting device with a hydraulic cylinder and a lever arm, so that the adjustment of the axis takes place about a fixed point arranged on the stand. Such an adjustment device is less expensive to manufacture and operate.

Wenn sehr große Verstellkräfte gefordert sind, ist die Verstelleinrichtung nach Anspruch 3 mit zwei parallel zueinander angeordneten Hydraulikzylindern jeweils unterhalb der Trommelachse und symmetrisch auf jeder Seite der Achsmitte besonders vorteilhaft, da die Verstellkraft verdoppelt wird.If very large adjustment forces are required, the adjustment device according to claim 3 with two hydraulic cylinders arranged parallel to each other below the drum axis and symmetrically on each side of the center of the axis is particularly advantageous since the adjustment force is doubled.

Ausführungsbeispiele der Erfindung werden in den Zeichnungen gezeigt und nachfolgend erläutert.Embodiments of the invention are shown in the drawings shown and explained below.

Die in Fig. 1 dargestellte Presse besteht aus dem Ständer 1, der die zentrale Preßtrommel 2 aufnimmt.The press shown in Fig. 1 consists of the stand 1, which receives the central press drum 2.

Der Preßtrommel 2 sind die Andrückwalzen 3, 4 und 5 zugeordnet.The pressure rollers 2, the pressure rollers 3, 4 and 5 are assigned.

Ein endloses Stahlband 6 wird von der Spannwalze 7, die in Richtung des Pfeiles 8 verstellbar ist, unter hoher Zugspannung gesetzt. Das Stahlband umschlingt die Preßtrommel 2, die Umlenkwalze 9, die Spannwalze 7 und die Andrückwalze 3 .An endless steel belt 6 is placed under high tension by the tension roller 7, which is adjustable in the direction of arrow 8. The steel belt wraps around the press drum 2, the deflection roller 9, the tension roller 7 and the pressure roller 3.

Die Andrückwalzen 3, 4 und 5 sind durch nicht gezeigte Hydraulikzylinder in Richtung der Achse der Preßtrommel 2 verstellbar.The pressure rollers 3, 4 and 5 are adjustable in the direction of the axis of the press drum 2 by hydraulic cylinders, not shown.

Die Verstellung der Preßtrommel 2 erfolgt durch Hydraulikzylinder 10 und 11, die an dem Zusatzlager 12 und an den Konsolen 13 angelenkt sind.The adjustment of the press drum 2 is carried out by hydraulic cylinders 10 and 11 which are articulated on the additional bearing 12 and on the brackets 13.

Bei der in Fig. 2 gezeigten Draufsicht sind die auf beiden Seiten der Preßtrommel 2 angeordneten Verstelleinrichtungen eingezeichnet, die alternativ auch mit nur einem mittig angeordneten Hydraulikzylinder 11 arbeiten können, der auf einer oberhalb der Trommelachse 17 angeordneten Konsole 13 abgestützt ist.In the plan view shown in FIG. 2, the adjustment devices arranged on both sides of the press drum 2 are drawn in, which can alternatively also work with only one centrally arranged hydraulic cylinder 11, which is supported on a console 13 arranged above the drum axis 17.

In Fig. 3 wird eine weitere Ausführungsform der Verstelleinrichtung gezeigt, die einen Hydraulikzylinder 15 und einen Lenker 14 vorsieht, die auf Konsolen 13 abgestützt sind.3 shows a further embodiment of the adjustment device, which provides a hydraulic cylinder 15 and a link 14 which are supported on brackets 13.

Durch eine Betätigung des Hydraulikzylinders 15 wird das Zusatzlager 12 angehoben bzw. abgesenkt, je nach Anordnung der Verstelleinrichtung.By actuating the hydraulic cylinder 15, the additional bearing 12 is raised or lowered, depending on the arrangement of the adjusting device.

In Fig. 4 wird eine Verstelleinrichtung auf der einen Seite der Preßtrommel 2 im Detail dargestellt.4 shows an adjusting device on one side of the press drum 2 in detail.

Auf dem Zapfen 17 der Preßtrommel ist ein Hauptlager 16, bestehend aus einem Lagerkörper mit einem Innenring 18, den Wälzkörpern 19 und dem Außenring 20 angeordnet. Weiter außen auf dem Zapfen 17 ist das Zusatzlager 12 angeordnet, bestehend aus dem Lagerkörper und einreihigen Zylinderrollenlager 21. An dem Lagerkörper des Zusatzlagers 12 ist der Hydraulikzylinder 11 angelenkt, der sich auf der, an dem Ständer 1 befestigten Konsole 13 abstützt.A main bearing 16, consisting of a bearing body with an inner ring 18, the rolling bodies 19 and the outer ring 20, is arranged on the pin 17 of the press drum. Further out on the pin 17, the additional bearing 12 is arranged, consisting of the bearing body and single-row cylindrical roller bearing 21. The hydraulic cylinder 11 is articulated on the bearing body of the additional bearing 12, which is supported on the bracket 13 fastened to the stand 1.

Durch eine Betätigung des Hydraulikzylinders 11 wird das Zusatzlager heruntergerückt, so daß die Montagetoleranz zwischen dem Lagerkörper des Hauptlagers 16 und dem Ständer 1, d.h. der Spalt 25 und das Spiel 23 zwischen den Wälzkörpern 19 und dem Außenring 20 aufgehoben wird.By actuating the hydraulic cylinder 11, the additional bearing is moved down, so that the assembly tolerance between the bearing body of the main bearing 16 and the stator 1, i.e. the gap 25 and the game 23 between the rolling elements 19 and the outer ring 20 is canceled.

Bei der in Fig. 1 gezeigten Ausführungsform wird durch Betätigen der Hydraulikzylinder 10, 11 das Montagespiel 24 zwischen den einzelnen Ständerteilen 25, 26, und 27 aufgehoben.In the embodiment shown in FIG. 1, by actuating the hydraulic cylinders 10, 11, the assembly play 24 between the individual stand parts 25, 26, and 27 canceled.

Bei der Verpressung einer Faserplattenbahn einer Dicke von 1,5 mm muß ein Preßspalt dieser Dicke zwischen den Andrückwalzen 3, 4 und 5 und der Preßtrommel 2 einstellbar sein, wobei die Dicke des Stahlbandes 6 von etwa 1,8 mm auch noch zu berücksichtigen ist.When pressing a fiberboard sheet with a thickness of 1.5 mm, a press nip of this thickness must be adjustable between the pressure rollers 3, 4 and 5 and the press drum 2, the thickness of the steel band 6 of about 1.8 mm also having to be taken into account.

Beim Anfahren der Anlage wird daher, um ein Plattwalzen des endlosen Stahlbandes zu vermeiden, die Preßtrommel mittels der Hydraulikzylinder 10 und 11 angehoben, wodurch das Montagespiel 24 zwischen den Ständerteilen 25 und 26, was etwa 1,5 mm beträgt, sich nicht auf die Bahndicke auswirken kann.When starting up the system, the press drum is therefore raised by means of the hydraulic cylinders 10 and 11 in order to prevent the endless steel strip from rolling flat, as a result of which the assembly play 24 between the stand parts 25 and 26, which is approximately 1.5 mm, does not depend on the web thickness can impact.

Weiterhin wird das Spiel 23 zwischen dem Außenring 20 und den Wälzkörpern 19 sowie das Montagespiel 25 zwischen dem Lagerkörper des Hauptlagers 16 und dem Ständer ausgeschaltet.Furthermore, the game 23 between the outer ring 20 and the rolling elements 19 and the assembly game 25 between the bearing body of the main bearing 16 and the stator are switched off.

Nunmehr kann mittels eines Transportbandes 28 die aufgestreute Faserschicht in die Presse eingegeben und eine Faserplatte 22 mit einer Dicke von 1,5 mm verpreßt werden, ohne daß beim Anfahren Schäden an der Maschine entstehen. Wenn die Presse leergefahren wird, verhindern die Hydraulikzylinder 10 und 11 ebenfalls, daß die etwa 110 t schwere Trommel auf das zwischen den Andrückwalzen 3, 4 und 5 und dem Trommelmantel 2 angeordnete Stahlband sowie auch auf die Andrückwalzen selbst schädlich einwirkt.Now the scattered fiber layer can be entered into the press by means of a conveyor belt 28 and a fiberboard 22 with a thickness of 1.5 mm can be pressed without causing damage to the machine when starting up. When the press is run empty, the hydraulic cylinders 10 and 11 also prevent the drum, which weighs about 110 tons, from acting deleteriously on the steel belt arranged between the pressure rollers 3, 4 and 5 and the drum shell 2, and also on the pressure rollers themselves.
