Description

Die Erfindung betrifft eine Presse zum Verdichten von Material insbesondere Abfall durch einen Stempel bzw. eine Preßplatte, der bzw. die in einer Kammer verschiebbar und durch mindestens eine Zylinder-Kolben-Einheit angetrieben ist, die seitlich der Kammer liegt und in der Ausgangsstellung, in der das Material noch nicht verdichtet ist, eingefahren und in der Endstellung, in der das Material maximal verdichtet ist, ausgefahren ist.The invention relates to a press for compacting material, in particular waste, by means of a stamp or a press plate which is displaceable in a chamber and is driven by at least one cylinder-piston unit which lies to the side of the chamber and in the starting position, in that the material has not yet been compacted, retracted and extended in the end position in which the material is maximally compressed.

Es ist bekannt, Abfall, wie z.B. Papier, in einer geschlossenen Kammer durch einen Stempel zu verdichten. Hierbei ist es auch bekannt, den Stempel durch zwei seitlich angeordnete Zylinder-Kolben-Einheiten zu bewegen, wobei der Stempel am Ende der jeweiligen Kolbenstange befestigt ist. Die Zylinder-Kolben-Einheiten stehen weit über die Kammer hinaus, so daß die Pressen große Außenabmessungen besitzen.It is known to compact waste, such as paper, in a closed chamber by means of a stamp. It is also known here to move the punch through two laterally arranged cylinder-piston units, the punch being attached to the end of the respective piston rod. The cylinder-piston units extend far beyond the chamber, so that the presses have large external dimensions.

Im Dokument DE-U-8709274 ist eine Konstruktion beschrieben, die einen hydraulischen Antrieb aus zwei seitlich neben dem Pressegehäuse in dessen oberen Bereich angeordnete Servoeinrichtungen jeweils in Form eines achsenparallel zu diesen gerichteten, in einen Zylinder eingesetzten und beidseitig von Druckmitteln beaufschlagbaren Kolbens aufweist, deren Kolbenstangen über Winkelhebel mit der Verdichtungsplatte trieblich verbunden sind. Diese Konstruktionsweise verkleinert zwar die Außenabmessungen der Vorrichtung, erreicht dies aber nur über technisch aufwendige Kolben- bzw. Kolbenstangenbauelemente, die die Verdichtungsplatte führen.Document DE-U-8709274 describes a construction which has a hydraulic drive consisting of two servo devices arranged laterally next to the press housing in the upper region thereof, each in the form of an axis parallel to the latter, inserted in a cylinder and loaded on both sides by pressure medium, the piston of which Piston rods are operatively connected to the compression plate via an angle lever. Although this design reduces the external dimensions of the device, this can only be achieved using technically complex piston or piston rod components which guide the compression plate.

Aufgabe der Erfindung ist es, eine Presse der eingangs genannten Art so zu verbessern, daß sie bei geringer Außenabmessung einen großen Stempelweg bzw. ein großes Kammervolumen und bei einer einfachen Konstruktion eine hohe Kippsicherheit des Stempels trotz maximaler Druckausübung aufweist.The object of the invention is to improve a press of the type mentioned in such a way that it has a large stamp travel or a large chamber volume with a small external dimension and a high safety against tipping of the stamp despite maximum pressure with a simple construction.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Stempel oder ein Stempelträger nicht an einer Kolbenstange, sondern am Zylinder selbst und zwar an dem Zylinderende, an dem die Kolbenstange austritt, befestigt ist. Dabei liegt der Zylinder parallel und seitlich des Weges, an dem der Stempel sich bewegt.This object is achieved in that the stamp or a stamp carrier is not attached to a piston rod, but to the cylinder itself, specifically at the end of the cylinder at which the piston rod emerges. The cylinder is parallel and to the side of the path on which the stamp moves.

Durch eine solche Konstruktion stehen die Zylinder-Kolben-Einheiten im eingefahrenen Zustand nicht oder nicht wesentlich in Richtung des Stempelweges über die Presse hinaus, so daß die Außenabmessungen der Presse weder in eingefahrener noch in der außgefahrenen Stellung wesentlich größer sind als das Kammervolumen.Such a construction means that the cylinder-piston units are not or not substantially in the direction of the ram path beyond the press in the retracted state, so that the external dimensions of the press are neither in the retracted nor in the extended position are much larger than the chamber volume.

Besonders vorteilhaft ist es hierbei, wenn ein Zylinderende in Höhe der Stempelstellung liegt, in der sich der Stempel in einer Ausgangsstellung befindet, und das andere Zylinderende in Höhe der Stempelstellung liegt, in der sich der Stempel in seiner Endstellung befindet.It is particularly advantageous here if one cylinder end is at the level of the stamp position in which the stamp is in an initial position and the other cylinder end is at the level of the stamp position in which the stamp is in its end position.

Vorzugsweise wird vorgeschlagen, daß der Stempel einen Querträger aufweist, der an den Zylinder-Kolben-Einheiten insbesondere an den Zylindern befestigt ist und mindestens eine Zylinder-Kolben-Einheit trägt, an der die Stempelpreßfläche befestigt und weiter in die Verdichtungskammer bewegbar ist. Durch diese weitere Zylinder-Kolben-Einheit kann eine zusätzliche noch stärkere Verdichtung des Materials erreicht werden. Von größtem Vorteil ist bei allen Ausführungsbeispielen, daß zum Erzeugen der Preßkraft stets die Kolbenseite mit Druck beaufschlagt wird, die der Kolbenstangenbefestigung gegenüber liegt, so daß die Zylinder-Kolben-Einheiten einen maximalen Druck bei der Material-Verpressung aufbringen können. Der Rückhub ohne Preßvorgang erfolgt dann mit dem geringeren Druck auf der Ringseite des Zylinders.It is preferably proposed that the stamp has a cross member which is attached to the cylinder-piston units, in particular to the cylinders, and carries at least one cylinder-piston unit, to which the stamp press surface is attached and can be moved further into the compression chamber. With this additional cylinder-piston unit, an even stronger compression of the material can be achieved. The greatest advantage of all embodiments is that the piston side is always pressurized to generate the pressing force, which is opposite the piston rod attachment, so that the cylinder-piston units can apply a maximum pressure during material compression. The return stroke without the pressing process then takes place with the lower pressure on the ring side of the cylinder.

Besonders vorteilhaft ist es, wenn jeder Zylinder an seiner Außenseite eine Führung aufweist. Hierbei kann die Führung des Zylinders von einem Rohr gebildet sein, das den Zylinder koaxial umgibt und in das der Zylinder in seiner Endpresstellung am weitesten eingefahren ist. Auch kann das Führungsrohr sich etwa über die Höhe der Maschine erstrecken und in seiner oberen Hälfte einen Schlitz für das Befestigungsteil des Stempels aufweisen. Um bewegliche Anschlüsse am Zylinder und damit Ausfälle zu verhindern, wird vorgeschlagen, daß die in die Zylinderkolbeneinheit führenden Druckleitungen durch das Innere der Kolbenstange verlaufen. Hierbei können die Druckleitungen Bohrungen in der Kolbenstange sein. Auch können die Druckleitungen Schlauch- oder Rohrleitungen im Inneren der Kolbenstange sein.It is particularly advantageous if each cylinder has a guide on its outside. The guide of the cylinder can be formed by a tube which coaxially surrounds the cylinder and into which the cylinder is most extended in its final pressing position. The guide tube can also extend approximately over the height of the machine and have a slot in its upper half for the fastening part of the stamp. In order to prevent movable connections on the cylinder and thus failures, it is proposed that the in the Cylinder-piston leading pressure lines run through the interior of the piston rod. The pressure lines can be bores in the piston rod. The pressure lines can also be hose or pipe lines inside the piston rod.

Eine besonders kippsichere Ausführung wird dann geschaffen, wenn an der Zylinder-Kolben-Einheit, insbesondere am Zylinder ein Querelement befestigt ist, an dessen beiden Enden je ein Befestigungselement befestigt ist, das mit dem Stempel bzw. der Preßplatte verbunden ist, wobei jedes Befestigungselement in einem eigenen Schlitz der Kammerwand gleitet. Vorteilhafte Ausführungen sind in den weiteren Unteransprüchen enthalten.A particularly tip-proof design is created when a cross element is fastened to the cylinder-piston unit, in particular to the cylinder, at each end of which a fastening element is fastened, which is connected to the stamp or the press plate, each fastening element in a separate slot in the chamber wall slides. Advantageous designs are contained in the further subclaims.

Wahlweise große oder kleine Ballen lassen sich pressen, wenn die Zylinder-Kolben-Einheiten in ihrer Höhe verstellbar sind und vorzugsweise der Stempel (Preßplatte) am Zylinder in einem Abstand zum oberen Zylinderende befestigt ist. Hierbei können die zum Anheben der Zylinder-Kolben-Einheit nach oben verlängerten Kolbenstangen Gewinde, insbesondere Sägezahngewinde aufweisen, auf denen jeweils ein Rad mit Innengewinde geschraubt ist, wobei alle Räder synchron insbesondere durch eine Kette antreibbar sind.Large or small bales can be pressed if the height of the cylinder-piston units is adjustable and preferably the punch (press plate) is attached to the cylinder at a distance from the upper end of the cylinder. Here, the piston rods, which are elongated upwards to lift the cylinder-piston unit, can have threads, in particular sawtooth threads, on each of which a wheel with an internal thread is screwed, all wheels being driven synchronously, in particular by a chain.

Die Presse weist eine quaderförmige Kammer 1 auf, in der ein waagerechter Stempel bzw. eine Preßplatte 2 senkrecht auf- und abfahrbar ist, dessen waagerechter Querschnitt dem Innenquerschnitt der Kammer 1 entspricht.The press has a cuboid chamber 1, in which a horizontal punch or a press plate 2 can be moved up and down vertically, the horizontal cross section of which corresponds to the inner cross section of the chamber 1.

Aufeinander gegenüberliegenden Seiten sind außerhalb der Kammer 1 je eine Zylinder-Kolben-Einheit 3 senkrecht befestigt, die jeweils einen Zylinder 4, einen Kolben 5 und eine Kolbenstange 6 aufweisen. Das aus dem Zylinder austretende Ende 6a der Kolbenstange 6 ist an einem waagerechten Querträger 7 befestigt, der an der Unteroder der Oberseite der Kammer 1 befestigt ist.A cylinder-piston unit 3, each having a cylinder 4, a piston 5 and a piston rod 6, are vertically fastened on sides opposite one another outside the chamber 1. The end 6a of the piston rod 6 emerging from the cylinder is fastened to a horizontal cross member 7 which is fastened to the bottom or the top of the chamber 1.

Die Kolbenstangen 6 mit dem Kolben 5 sind damit unbeweglich seitlich der Kammer 1 befestigt und bei Aufgabe eines Druckmediums insbesondere einer Hydraulikflüssigkeit auf der Kolbenseite, die der Kolbenstange 6 gegenüberliegt, fahren beide Zylinder 4 nach unten. Hierbei nehmen sie den Stempel 2 mit, der an aufeinander gegenüberliegenden Seiten an den Zylindern 4 an den Zylinderenden befestigt ist, an denen die Kolbenstangen 6 austreten.The piston rods 6 with the piston 5 are thus immovably attached to the side of the chamber 1 and at Applying a pressure medium, in particular a hydraulic fluid on the piston side opposite the piston rod 6, both cylinders 4 move downwards. In doing so, they take the stamp 2 with them, which is attached to the cylinders 4 at the cylinder ends on opposite sides, at which the piston rods 6 exit.

Nach diesem Preßweg des Stempels 2 und der beiden Zylinder 4 befinden sie sich in der in Fig. 1 gestrichelt dargestellten Stellung.
Soll das Material 8 noch weiter mit noch höherem verdichtet werden, so kann dies durch eine dritte größer dimensionierte Zylinder-Kolben-Einheit 9 erfolgen, die am Stempel 2 bzw. an einem Querträger 10 befestigt ist, der statt des Stempels 2 an den oberen Enden der Zylinder 4 fest ist. Die Kolbenstange 11 der dritten Zylinder-Kolben-Einheit 9 trägt am unteren Ende den Stempel 2, der hierdurch noch weiter nach unten in die Kammer einfahrbar ist, Fig. 2.After this pressing path of the stamp 2 and the two cylinders 4, they are in the position shown in dashed lines in FIG. 1.
If the material 8 is to be compressed still further, this can be done by a third, larger-sized cylinder-piston unit 9, which is attached to the punch 2 or to a cross member 10, which instead of the punch 2 at the upper ends the cylinder 4 is fixed. The piston rod 11 of the third cylinder-piston unit 9 carries the plunger 2 at the lower end, which can thereby be moved further down into the chamber, FIG. 2.

Ferner sind die zu demZylinder 9, Figur 2 und Figur 4 führenden (Druck-) Leitungen teleskopisch ausgebildet.Furthermore, the (pressure) lines leading to the cylinder 9, FIG. 2 and FIG. 4 are telescopic.

Diese weitere Zylinder-Kolben-Einheit 9 kann aber auch auf der gegenüberliegenden Seite der Kammer 1 angeordnet sein, wie dies Fig. 3 zeigt. Dann wird das zwischen beiden Kolben 2,2a befindliche Material von zwei Seiten her zusammengedrückt.This further cylinder-piston unit 9 can also be arranged on the opposite side of the chamber 1, as shown in FIG. 3. Then the material located between the two pistons 2, 2 a is compressed from two sides.

Im Ausführungsbeispiel nach Fig. 4 ist die Presse nach Fig. 2 waagerecht liegend angeordnet, wobei die Kammer 1 auf der dem Stempel gegenüberliegenden Seite eine Tür 12 aufweist, die während des Preßvorganges fest verschlossen ist und danach geöffnet werden kann, um das verdichtete Material herausnehmen zu können. Eine solche Tür ist bei den Pressen nach Fig. 1 und 2 an der Vorderseite der Kammer 1 in zweigeteilter Form angeordnet.In the exemplary embodiment according to FIG. 4, the press according to FIG. 2 is arranged lying horizontally, the chamber 1 having a door 12 on the side opposite the stamp, which is firmly closed during the pressing process and can then be opened in order to take out the compacted material to be able to. Such a door is arranged in two parts in the presses of FIGS. 1 and 2 on the front of the chamber 1.

Jeder Zylinder kann an seiner Außenkante eine Führung aufweisen. Die Führung des Zylinders ist hierbei von einem Rohr gebildet, das den Zylinder koaxial umgibt und in das der Zylinder in seiner Endpresstellung am weitesten eingefahren ist. Das Führungsrohr erstreckt sich etwa über die Höhe der Maschine und weist in seiner oberen Hälfte einen Schlitz für das Befestigungsteil des Stempels auf. Die in die Zylinderkolbeneinheit führenden Druckleitungen verlaufen durch das Innere der Kolbenstange. Hierbei können die Druckleitungen Bohrungen in der Kolbenstange sein. Die Druckleitungen können auch Schlauch- oder Rohrleitungen im Inneren der Kolbenstange sein.Each cylinder can have a guide on its outer edge. The guidance of the cylinder is in this case formed by a tube which coaxially surrounds the cylinder and into which the cylinder is most extended in its final pressing position. The guide tube extends approximately over the height of the machine and has a slot in its upper half for the fastening part of the stamp. The pressure lines leading into the cylinder-piston unit run through the interior of the piston rod. The pressure lines can be bores in the piston rod. The pressure lines can also be hose or pipe lines inside the piston rod.

In einer nicht dargestellten Ausführung ist nur auf einer Außenseite der Kammer 1 eine Zylinder-Kolben-Einheit 3 angeordnet.In an embodiment not shown, a cylinder-piston unit 3 is arranged only on an outside of the chamber 1.

Im Ausführungsbeispiel nach Fig. 5 ist an der Zylinder-Kolben-Einheit, insbesondere am Zylinder 4 ein Querelement 13 befestigt, das zu beiden Seiten des Zylinders 4 vorsteht und an dessen beiden Enden je ein profilförmiges Befestigungselement befestigt ist. Die beiden Befestigungselemente ragen durch jeweils einen Schlitz 15 durch die Kammerwand 19 hindurch und sind am Stempel 2 bzw. an der Pressplatte befestigt. Auf jedem Befestigungselement kann eine Rolle 14 gelagert sein, die in dem jeweiligen Schlitz 15 läuft.In the exemplary embodiment according to FIG. 5, a cross element 13 is fastened to the cylinder-piston unit, in particular to the cylinder 4, which projects on both sides of the cylinder 4 and on each end of which a profile-shaped fastening element is fastened. The two fastening elements each protrude through a slot 15 through the chamber wall 19 and are fastened to the punch 2 or to the press plate. A roller 14, which runs in the respective slot 15, can be mounted on each fastening element.

Die zwei Seitenwände jedes Schlitzes sind vorzugsweise durch U-förmige Profile 18 auf der Außenseite verstärkt, auf denen die Rolle läuft.The two side walls of each slot are preferably reinforced on the outside by U-shaped profiles 18 on which the roller runs.

In nicht dargestellten Ausführungen bilden die beiden Befestigungselemente 12 zusammen mit dem Stempel bzw. der Preßplatte 2 ein U-förmiges, starres Element. In der hohlen Kolbenstange 6 liegt eine Hydraulikleitung, und der insbesondere im Querschnitt ringförmige Raum zwischen der Außenseite der Hydraulikleitung und der Innenseite der Kolbenstangeninnenwand ist als weitere Hydraulikleitung benutzt.In versions not shown, the two fastening elements 12 form together with the stamp or the Press plate 2 is a U-shaped, rigid element. A hydraulic line lies in the hollow piston rod 6, and the space, in particular with an annular cross section, between the outside of the hydraulic line and the inside of the piston rod inner wall is used as a further hydraulic line.

Figur 6 zeigt verlängerte Kolbenstangen 6 mit Sägezahn-Außengewinde und zwei am Gehäuse oder Maschinengestell gelagerte Kettenräder 20, die mit Hilfe einer Kette 21 gleichzeitig gedreht werden können. Dies führt zur gleichzeitigen Anhebung aller Zylinder-Kolben-Einheiten mit Preßplatte. Bei dieser Version ist die Preßplatte 2 etwas tiefer am Zylinder 4 befestigt, um kleinere Ballen pressen zu können. Wenn die gesamte Einheit über die Kettenräder hochgestellt wird, können dann wieder so große Ballen wie in Figur 1 gezeigt, gefertigt (gepresst) werden und zwar bei voller Nutzung der maximalen Kammer-Höhe.FIG. 6 shows elongated piston rods 6 with a sawtooth external thread and two chain wheels 20 mounted on the housing or machine frame, which can be rotated simultaneously with the aid of a chain 21. This leads to the simultaneous lifting of all cylinder-piston units with a press plate. In this version, the press plate 2 is attached somewhat lower to the cylinder 4 in order to be able to press smaller bales. If the entire unit is raised above the sprockets, bales as large as shown in FIG. 1 can then be produced (pressed), with full use of the maximum chamber height.
