Description

Die Erfindung betrifft eine Kompaktierpresse gemäß den oberbegrifflichen Merkmalen des Patentanspruches 1.The invention relates to a compacting press according to the generic features of claim 1.

Kompaktierpressen in der Ausbildung als Brikettierpressen sind aus der DE-PS 33 33 766 und der DE-A-30 38 839 bekannt. Hierbei ist ein Vorverdichterkolben einem horizontal hin- und herbewegbaren Preßstempel vorgeschaltet. Die Vorverdichtungskammer, in die der Vorverdichterkolben eintaucht, wird von einer Zuführvorrichtung, z. B. einer Zuführschnecke beschickt. Der horizontale Preßstempel verdichtet das somit geringfügig vorverdichtete Material in einem nachgeschalteten, scheibenförmigen Formwerkzeug, das mehrere Formkammern aufweist. Die rückwärtige Stirnseite des drehbaren Formwerkzeuges ist hierbei als Gegendruckplatte von einer feststehenden Stirnplatte abgeschlossen, gegen die der horizontale Preßstempel das Preßgut verdichtet. Bei dieser bekannten Vorrichtung wird ein bei einem vorausgegangenen Preßvorgang gepreßter Brikett aus dem scheibenförmigen Formwerkzeug ausgestoßen und dann von einer Stapelvorrichtung, beispielsweise einem Förderband abgeführt.Compacting presses in training as briquetting presses known from DE-PS 33 33 766 and DE-A-30 38 839. Here is a pre-compression piston horizontally back and forth movable press upstream. The Pre-compression chamber into which the pre-compression piston is immersed, is fed by a feed device, e.g. B. a feed screw loaded. The horizontal press ram thus compresses this slightly pre-compressed material in a downstream, disc-shaped mold, which has several mold chambers. The rear end of the rotatable mold is here as a counter pressure plate from a fixed end plate completed against which the horizontal ram presses the material to be pressed condensed. In this known device one at a previous pressing process pressed briquette from the disc-shaped mold ejected and then from one Stacking device, for example removed from a conveyor belt.

Aufgrund des horizontal angeordneten Preßstempels weist die bekannte Kompaktierpresse eine große Stellfläche auf, was im industriellen Einsatz zum Verdichten von Laub oder Holzabfällen von nachrangiger Bedeutung ist. Für die Anwendung als Kompaktierpresse für Altpapier oder Abfallpapier im Haushalts- oder Bürobereich spielt jedoch die Stellfläche eine vorrangige Rolle, ebenso die Möglichkeit, eine große Anzahl von Preßlingen platzsparend zwischenzulagern.Due to the horizontally arranged ram, the known compacting press a large footprint on what in industrial use for compacting leaves or wood waste is of secondary importance. For use as Compacting press for waste paper or waste paper in household or However, office space plays a primary role Role, as well as the possibility of a large number of compacts intermediate storage to save space.

Eine gattungsgemäße Kompaktierpresse ist aus der US-PS 3,651,755 und in ähnlicher Form aus der US-PS 3,563,164 bekannt. In der WO 93/19930 ist weiterhin eine Kompaktierpresse beschrieben, die jedoch keinen Sammelbehälter zur Zwischenlagerung der Preßlinge aufweist. Aus der DE-U-76 36 727 ist zudem eine Haushaltspresse für Dosen oder Flaschen bekannt, die jedoch nur eine Zerstörung der Flaschen oder Dosen mittels eines unter seinem Eigengewicht herabfallenden Kolbens, jedoch keine bleibende Verformung und Verpressung bewirkt. All diese Vorrichtungen weisen jedoch im Vergleich zur möglichen Zwischenlagerungskapazität einen großen Stellplatzbedarf oder platzraubende Bauweise auf.A generic compacting press is known from US Pat. No. 3,651,755 and known in a similar form from US Pat. No. 3,563,164. In the WO 93/19930 also describes a compacting press which however no collecting container for the intermediate storage of the compacts having. A household press is also from DE-U-76 36 727 Known for cans or bottles, but only a destruction of the bottles or cans by means of one under its own weight falling piston, but no permanent deformation and Pressing causes. However, all of these devices have A large one compared to the possible intermediate storage capacity Space requirement or space-consuming construction.

Weiterhin sind in Fortentwicklung von Papierreißwölfen oder sog. Aktenvernichtern, die Papier durch Schneidwalzen leiten und dann unverdichtet einem Beutel zuführen, Pressen bekannt geworden, die nach Zerkleinerung die Papierstreifen in einer horizontalen Strangpresse verdichten und seitlich zu einem Behälter ausstoßen. Obwohl somit eine weitere Kompaktierung der Papierstreifen erreicht wird, ist eine erhebliche Stellfläche erforderlich, da neben der ca. 1,5 m langen Preßvorrichtung noch ein Behälter mit etwa einem halben Kubikmeter Fassungsvermögen aufgestellt wird, um den Behälter nicht übermäßig oft entleeren zu müssen.Furthermore, paper shredders or so-called. Shredders that feed paper through cutting rollers and then feed it into a bag without compression, presses become known, after shredding the paper strips in a horizontal Compact the extrusion press and turn it into a container expel. Although thus further compacting the Stripping paper is a significant footprint required because in addition to the approx. 1.5 m long pressing device a container with a capacity of about half a cubic meter is set up so that the container is not emptied too often to have to.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, eine Kompaktierpresse zu schaffen, die eine geringe Stellfläche aufweist und somit möglichst kompakte Abmessungen bei hoher Preßdichte ermöglicht.Accordingly, the invention is based on the object Compacting press to create a small footprint has and thus the most compact dimensions with high Press density enables.

Diese Aufgabe wird gelöst durch eine Kompaktierpresse gemäß den Merkmalen des Patentanspruches 1.This object is achieved by a compacting press according to the Features of claim 1.

Durch die Anordnung des Preßstempels in Vertikalrichtung über einen Preßling-Behälter zur Zwischenlagerung der geformten Preßlinge wird eine geringe Stellfläche erreicht, die im wesentlichen nur durch die Grundfläche des Behälters für die Zwischenlagerung der Preßlinge bestimmt wird. Der Preßling-Behälter nimmt dabei etwa ein Drittel der Bauhöhe der Kompaktierpresse ein, so daß sich ein Fassungsvermögen von ca. einem halben Kubikmeter ergibt. Die Kompaktierpresse ist aufgrund ihrer kompakten Bauweise noch gut transportabel. Die angestrebte hohe Preßdichte wird dadurch erreicht, daß die Formkammer durch einen in Horizontalrichtung verschiebbaren Verschlußschieber in der Preßstellung abgeschlossen wird. Beim Ausschieben des so in der Formkammer hochverdichteten Preßlinges durch den Preßstempel selbst, ist keine gesonderte Ausstoßvorrichtung erforderlich, so daß der Bauaufwand für die kompakt bauende Kompaktierpresse gering bleibt.By arranging the ram in the vertical direction a compact container for intermediate storage of the molded A small footprint is achieved in the essential only by the footprint of the container for the Interim storage of the compacts is determined. The compact container takes about a third of the overall height of the Compacting press so that there is a capacity of approx. is half a cubic meter. The compacting press is due to its compact design it is still easy to transport. The desired high density is achieved in that the Molding chamber by a horizontally displaceable Locking slide is completed in the pressing position. At the Pushing out the compact so highly compressed in the molding chamber by the press die itself is not a separate one Ejection device required, so that the construction costs for the compact compacting press remains low.

In bevorzugter Ausführung weist der Verschlußschieber an seiner Unterseite einen oder mehrere Mitnehmer auf, die bei sich füllendem Preßling-Behälter die Preßlinge seitlich wegfördern und somit eine vollständige Füllung des Preßling-Behälters erreichen. Dies erfolgt in vorteilhafter Weise zugleich mit der Schließ/Öffnungsbewegung des Verschlußschiebers, so daß keine gesonderten Antriebe erforderlich sind. In vorteilhafter Ausführung ist der Preßling-Sammelbehälter als Rollcontainer mit bis etwa einem halben Kubikmeter Fassungsvermögen ausgebildet, so daß aufgrund der hohen Preßdichte und der vollständigen Füllung des Behälters die Entleerung nur selten erfolgen muß. Hierdurch wird insgesamt eine Kompaktierpresse geschaffen, die sich insbesondere für Anwendungen in Büros als Ersatz für Aktenvernichter oder Reißwolf eignet, wobei im Bereich des Einfüllschachtes oder der Zuführvorrichtung zweckmäßigerweise ebenfalls mehrere übliche Schneidwalzen vorgesehen sein können.In a preferred embodiment, the slide valve has on it Underside one or more drivers on it Filling the compact container convey the compacts away to the side and thus a complete filling of the compact container to reach. This is advantageously done at the same time as the Closing / opening movement of the slide gate, so that none separate drives are required. In advantageous The compact container is designed as a roll container up to about half a cubic meter of capacity, so that due to the high density and full Filling the container, the emptying only rarely has to be done. This creates an overall compacting press that is particularly suitable for applications in offices as a replacement for Document shredder or shredder is suitable, being in the area of Filling chute or the feed device expediently also several conventional cutting rollers can be provided.

In bevorzugter Ausführung ist zudem die seitliche Einlaßöffnung zu der Formkammer bezüglich der Preßstempel-Achse asymmetrisch bzw. außermittig ausgebildet, so daß bei der Preßbewegung auf den Preßstempel ein Drehmoment um die aufrechte Achse des Preßstempels auf diesen ausgeübt wird, so daß sich dieser verdreht und damit die Schneidkante an der Preßstempel-Unterseite gleichmäßig abnutzt. Hierdurch wird eine besonders lange Standzeit der Schneidkante an der Preßstempel-Unterkante zum Abscheren des Preßgutes beim Übergang von der seitlichen Einlaßöffnung zu der Formkammer selbst erreicht.In a preferred embodiment, the side inlet opening is also asymmetrical to the mold chamber with respect to the press ram axis or formed off-center, so that during the pressing movement the ram a torque around the upright axis of the Press ram is exercised on this, so that this twisted and thus the cutting edge on the bottom of the press ram wears evenly. This makes one special Long service life of the cutting edge on the lower edge of the ram to shear off the pressed material during the transition from the side Inlet opening to the mold chamber itself reached.

Weitere vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.Further advantageous embodiments are the subject of dependent claims.

In Fig. 1 ist eine Kompaktierpresse 1 in perspektivischer Darstellung schematisch gezeigt, wobei das zu verpressende Papier, beispielsweise aus alten Aktenbeständen im wesentlichen von oben in einen Zuführschacht 2 eingefüllt wird. Im unteren Bereich dieses Zuführschachtes 2 können auch übliche Schneidwalzen 25 eines Reißwolfes vorgesehen sein (vgl. Fig. 2), so daß das zu verpressende Papier in Streifen geschnitten wird. Unterhalb des Zuführschachtes 2 ist eine Zuführvorrichtung 3 in horizontaler Ausrichtung vorgesehen, beispielsweise eine Förderschnecke oder eine Förderwendel, die das Papiermaterial durch eine seitliche Einlaßöffnung 7 in eine Formkammer 6 fördert, über der ein in der Formkammer 6 auf- und abgehender Preßstempel 4 und ein Preßzylinder 5 angeordnet ist, die in Fig. 2 genauer dargestellt sind. Nach Zuführung des Papiermaterials durch den seitlichen Einlaß 7 wird der Preßstempel 4 durch Beaufschlagung des Preßzylinders 5 mehrfach abgesenkt, wobei das Papiermaterial verdichtet wird. Hierbei ist eine untere Auslaßöffnung 8 der Formkammer 6 durch einen in Horizontalrichtung verschiebbaren Verschlußschieber 9 geschlossen. Der Verschlußschieber 9 ist in einer eingearbeiteten Schieberführung 10 (vgl. auch Fig. 4) geführt und in Horizontalrichtung durch einen Schieberantrieb 11, bevorzugt ebenfalls mit einem Hydraulikzylinder hin- und hergehend angetrieben. Der Antrieb erfolgt jeweils nach Erreichen eines bestimmten Preßvolumens. Der Verschlußschieber 9 weist eine Schieberöffnung 12 auf, die einen dem Querschnitt der Formkammer 6 entsprechenden Durchmesser oder geringfügig größer aufweist. Nach Bewegung des Verschlußschiebers 9 in die Auslaßposition stimmt die Schieberöffnung 12 mit der Auslaßöffnung 8 der Formkammer überein, so daß ein jeweils in der Formkammer 6 gepreßter Preßling 21 durch den nach unten bewegten Preßstempel 4 ausgestoßen wird und nach unten in einen Preßling-Behälter 20 fallen kann. Wenn sich in diesem Preßling-Behälter 20 die Preßlinge 21 auftürmen (vgl. auch Fig. 2), werden durch jeden Rückhub des Verschlußschiebers 9 und einem oder mehreren an seiner Unterseite angeordneten Mitnehmern 13 die jeweils obersten Preßlinge 21 zur Seite weg gefördert, so daß eine vollständige Füllung des Preßling-Behälters 20 erreicht wird. Die Lagerung der Schieber-Einheit erfolgt hierbei an einem Schieberrahmen 14, der bevorzugt an das Gehäuse der Formkammer 6 angeflanscht ist, um somit eine zuverlässige Abstützung der Kräfte beim Bewegen des Verschlußschiebers 9 zu erreichen. Dieser Schieberrahmen 14 ist im wesentlichen unterhalb dem Bereich der Zuführvorrichtung 3 angeordnet, deren Boden zugleich eine Abdeckung für den Schieberrahmen 14 bildet und diesen noch zusätzlich aussteifen kann. Die Zuführvorrichtung 3 ist dabei durch einen Antriebsmotor 15 angetrieben, der ebenfalls an dem Schieberrahmen 14 seitlich befestigt ist und in zweckmäßiger Ausbildung als Elektromotor ausgebildet ist, der bedarfsweise, z. B. bei einem bestimmten Füllstand im Einfüllschacht 2 eingeschaltet wird.In Fig. 1 is a compacting press 1 in perspective Diagram shown schematically, the one to be pressed Paper, for example, essentially from old files is filled from above into a feed shaft 2. At the bottom The area of this feed shaft 2 can also be conventional Cutting rollers 25 of a shredder can be provided (see FIG. 2), so that the paper to be pressed is cut into strips. Below the feed shaft 2 is a feed device 3 in horizontal alignment provided, for example a Screw conveyor or a spiral conveyor that holds the paper material through a lateral inlet opening 7 into a molding chamber 6 promotes, on the one in the mold chamber 6 up and down Press ram 4 and a press cylinder 5 is arranged, which in Fig. 2 are shown in more detail. After feeding the paper material through the side inlet 7, the ram 4 through Actuation of the press cylinder 5 lowered several times, which Paper material is compressed. Here is a lower one Outlet opening 8 of the mold chamber 6 through a Horizontal sliding slide 9 closed. The slide valve 9 is in one incorporated slide guide 10 (see also FIG. 4) and in the horizontal direction by a slide drive 11, preferably also back and forth with a hydraulic cylinder driven here. The drive takes place after Reaching a certain pressing volume. The locking slide 9 has a slide opening 12 which has a cross section of FIG Mold chamber 6 corresponding diameter or slightly larger having. After moving the slide 9 in the The outlet position agrees with the slide opening 12 Outlet opening 8 of the molding chamber match, so that one in each the molding chamber 6 pressed compact 21 through the down moving ram 4 is ejected and down into one Compactor container 20 can fall. If in this compact container 20 pile up the compacts 21 (cf. also FIG. 2), are by each return stroke of the slide valve 9 and one or several drivers 13 arranged on its underside the uppermost compacts 21 promoted to the side, so that a complete filling of the compact container 20 is reached becomes. The slide unit is mounted on one Slider frame 14, preferably on the housing of the molding chamber 6 is flanged to provide reliable support for the To achieve forces when moving the slide 9. This slide frame 14 is substantially below that Area of the feed device 3 arranged, the bottom of which at the same time forms a cover for the slide frame 14 and this still can additionally stiffen. The feed device 3 is there driven by a drive motor 15, which is also on the Slider frame 14 is attached laterally and in a more appropriate manner Training is designed as an electric motor, which, if necessary, e.g. B. at a certain fill level in the feed chute 2 is switched on.

Der Preßzylinder 5 bzw. der Preßstempel 4 ist hierbei durch eine Hydraulikpumpe 17 betrieben, die durch einen Antriebsmotor 16 angetrieben ist. Der Antriebsmotor 16 und die Hydraulikpumpe 17, die bevorzugt als Innenzahnradpumpe ausgebildet ist, sind dabei bevorzugt von einer Schalldämmkapsel umgeben, so daß die Kompaktierpresse 1 geräuscharm arbeitet. Hierzu trägt auch bei, wenn der Preßzylinder 5 einen mit der Hydraulikpumpe 17 verbundenen und für geringe Bauhöhe seitlich angeschlossenen Druckübersetzer 18 an seinem oberen Ende aufweist, so daß geringe Anschlußleistungen erforderlich sind. Die Aktivierung des an sich bekannten Druckübersetzers 18 und des Schieberantriebs 11 erfolgt dabei durch einen Wegaufnehmer 19, der bevorzugt im Zentrum des Preßzylinders 5 angeordnet ist und die jeweils erreichbare Eintauchtiefe des Preßstempels 4 erfaßt.The press cylinder 5 or the ram 4 is here by a Hydraulic pump 17 operated by a drive motor 16th is driven. The drive motor 16 and the hydraulic pump 17, which are preferably designed as an internal gear pump, are included preferably surrounded by a sound insulation capsule, so that the Compacting press 1 operates quietly. This also helps when the press cylinder 5 one with the hydraulic pump 17th connected and laterally connected for low overall height Has pressure intensifier 18 at its upper end, so that low connected loads are required. The activation of the known pressure translator 18 and Slider drive 11 takes place through a displacement sensor 19, which is preferably arranged in the center of the press cylinder 5 and the immersion depth of the press ram 4 which can be achieved in each case is detected.

In Fig. 2 ist eine Vorderansicht in teilweiser Schnittdarstellung der Kompaktierpresse 1 gezeigt, wobei die entsprechenden, in Zusammenhang mit Fig. 1 beschriebenen Bauteile mit dem gleichen Bezugszeichen versehen sind. Hieraus ist insbesondere die kompakte Bauweise der Presse ersichtlich, insbesondere der geringe Stellplatzbedarf bei einem Preßling-Behälter 20, der eine relativ große Aufnahmekapazität für die Preßlinge 21 aufweist. Der Preßling-Behälter 20 kann hierbei auf der, dem Betrachter zugewandten Vorderseite der Kompaktierpresse 1 nach vorne (Pfeil D in Fig. 3) herausgezogen werden, wobei ein Rahmenunterteil 30 nach vorne offen ist, so daß der Preßling-Behälter 20 nach Öffnen von Schwenktüren 23 gemäß Pfeil C in Fig. 3 in Art eines Rollcontainers nach vollständiger Füllung leicht aus der Presseneinheit entnommen und entleert werden kann. Das Rahmenunterteil 30 ist dabei bevorzugt aus Vierkantrohren aufgebaut, die zugleich als Ölreservoir für das Hydrauliköl dienen. Oberhalb des Rahmenunterteils 30 ist das blockförmige Gehäuse 31 für die Formkammer 6 ausgebildet, in dem der seitliche Einlaß 7, der untere Auslaß 8 und die Schieberführung 10 eingearbeitet ist (vgl. Fig. 4). An dieses blockförmige Gehäuse 31 ist zudem an der Seite der Schieberrahmen 14 angeflanscht und an der Oberseite mittels Befestigungsbohrungen 33 vertikale Zugstangen 32 zur Abstützung des Preßzylinders 5 befestigt. Durch diese modulare Bauweise ergibt sich ein geringer Bauaufwand und eine leichte Austauschbarkeit bei eventuellen Defekten.2 is a partial front view Sectional view of the compacting press 1 shown, the corresponding, described in connection with FIG. 1 Components are provided with the same reference numerals. Out of this the compact design of the press is particularly evident, in particular the low space requirement for a compact container 20, which has a relatively large capacity for the Has compacts 21. The compact container 20 can in this case the front of the compacting press facing the viewer 1 to the front (arrow D in Fig. 3) are pulled out, with a Lower frame part 30 is open to the front, so that the compact container 20 after opening swing doors 23 according to arrow C in Fig. 3 in the manner of a roll container after full filling can be easily removed from the press unit and emptied can. The lower frame part 30 is preferably made of Square tubes built, which also serve as an oil reservoir for the Serve hydraulic oil. This is above the lower frame part 30 block-shaped housing 31 formed for the mold chamber 6, in which the side inlet 7, the lower outlet 8 and the Slider guide 10 is incorporated (see. Fig. 4). To this block-shaped housing 31 is also on the side of the Flanged slide frame 14 and on the top by means of Mounting holes 33 vertical tie rods 32 for support of the press cylinder 5 attached. Thanks to this modular design there is little construction effort and an easy one Interchangeability in the event of defects.

In Fig. 3 ist die Draufsicht entlang der Schnittlinie A-A in Fig. 2 dargestellt. Hierbei ist neben der rahmenartigen Gestaltung des Rahmenunterteils 30 zur Aufnahme des Preßling-Behälters 20 mit Laufrollen 22 die massive Ausführung des Gehäuses 31 für die Formkammer 6 und die daran seitlich angeschlossene Schiebereinheit mit dem Schieberrahmen 14, den daran gelagerten Schieberantrieb 11 und dem hiervon betätigten Verschlußschieber 9 mit der Schieberöffnung 12 gezeigt. Hierbei befindet sich der Verschlußschieber 9 in der Verschlußstellung für die Formkammer 6. Nachdem das Preßgut durch die seitliche Einlaßöffnung 7 eingefüllt ist, verfährt der Preßstempel 4 nach unten in die Formkammer 6 und verdichtet somit das Preßgut, insbesondere das Altpapier. Nachdem mehrere derartiger Preßhübe durchgeführt worden sind, wird die durch den Preßstempel 4 erreichbare Eintauchtiefe in die Formkammer 6 immer geringer, was beispielsweise durch den Wegaufnehmer 19 festgestellt wird, jedoch auch über Drucksensoren oder außenliegende Wegmeßsysteme festgestellt werden kann. Wenn somit der Preßstempel 4 nurmehr etwa bis zu der seitlichen Einlaßöffnung 7 (bei dem vorbestimmten Arbeitsdruck) eindringen kann, wird der Schieberantrieb 11 betätigt, wobei die Schieberöffnung 12 gemäß Fig. 2 nach links verschoben wird, so daß diese in Übereinstimmung mit der unteren Auslaßöffnung 8 gelangt. Bei dem sich anschließenden Absenken des Preßstempels 4 wird somit der in der Formkammer 6 geformte Preßling 21 nach unten aus der Formkammer 6 ausgeschoben. Im sich daran anschließenden Rückhub des Verschlußschiebers 9 wird bei dem gleichzeitigen Wiederverschließen der Formkammer 6 der sich ggfs. noch im linken Bereich des Preßling-Behälters 20 befindliche Preßling nach rechts seitlich weggeschoben, so daß eine vollständige Füllung des Preßling-Behälters 20 erreicht werden kann.3 is the top view along the section line A-A in FIG Fig. 2 shown. In addition to the frame-like Design of the lower frame part 30 for receiving the compact container 20 with rollers 22 the massive version of the Housing 31 for the mold chamber 6 and the side of it connected slide unit with the slide frame 14, the slider drive 11 mounted thereon and the one actuated thereby Lock slide 9 shown with the slide opening 12. Here the slide valve 9 is in the closed position for the mold chamber 6. After the material to be pressed through the side The inlet opening 7 is filled, the ram 4 moves to below in the molding chamber 6 and thus compresses the material to be pressed, especially the waste paper. After several such press strokes have been carried out by the press ram 4th achievable immersion depth in the mold chamber 6 is becoming ever smaller, what is determined, for example, by the displacement sensor 19, but also via pressure sensors or external position measuring systems can be determined. So if the ram 4 only approximately up to the lateral inlet opening 7 (at the predetermined working pressure) can penetrate, the Slider drive 11 actuated, the slider opening 12 according to Fig. 2 is moved to the left so that this in Matches the lower outlet opening 8. In which Subsequent lowering of the ram 4 is thus the in the mold chamber 6 molded compact 21 down from the Mold chamber 6 pushed out. In the subsequent return stroke of the slide valve 9 is at the same time Resealing of the mold chamber 6 which may still be in the left area of the compact container 20 located compact pushed sideways to the right so that a complete Filling of the compact container 20 can be achieved.

In Fig. 4 ist die zugehörige Seitenansicht des Gehäuses 31 für die Formkammer 6 dargestellt. Hierdurch wird insbesondere die Führung des Verschlußschiebers 9 in der Schieberführung 10 ersichtlich, sowie die relativ einfache Bauweise. Hierbei ist, ebenso wie in Fig. 2, der nach unten in den Preßling-Behälter 20 hineinragende, an der Unterseite des Verschlußschiebers 9 angeordnete Mitnehmer 13 dargestellt, der zur seitlichen Wegförderung und damit möglichst vollständigen Befüllung des Preßling-Behälters 20 dient. 4 is the associated side view of the housing 31 for the mold chamber 6 shown. This will in particular Guiding the slide slide 9 in the slide guide 10 evident, as well as the relatively simple construction. Here is as in Fig. 2, the down into the compact container 20th protruding on the underside of the slide 9 arranged driver 13 shown, the lateral Promotion and thus complete filling of the Compacted container 20 is used.

Von besonderer Bedeutung ist hierbei die asymmetrisch gestaltete seitliche Einlaßöffnung 7, durch die die Zuführvorrichtung 3 das Preßgut, insbesondere das Altpapier in die Formkammer 6 fördert. Durch diese außermittige, asymmetrische Gestaltung der seitlichen Einlaßöffnung wird nämlich bei dem Nachuntenbewegen des Preßstempels 4 und damit ggfs. dem Abscheren von noch anhängenden Papierstreifen ein Drehmoment auf den Preßstempel 4 ausgeübt, so daß sich dieser um seine aufrechte Achse geringfügig verdreht. Hierdurch wird sichergestellt, daß die an der Unterseite des Preßstempels 4 ausgebildete Schneidkante 4a bei jedem Preßhub um einige Winkelgrade um die aufrechte Preßstempel-Achse weiterverdreht wird. Hierdurch wird die Standzeit der Schneidkante 4a an der Unterseite des Preßstempels 4 erheblich erhöht. Um diese Verdrehung des Preßstempels 4 zu erreichen, ist an seiner oberen Seite ein entsprechendes Lager 4b vorgesehen, um das sich der Preßstempel 4 frei drehen kann.Of particular importance here is the asymmetrical design lateral inlet opening 7 through which the feed device 3 Pressed material, especially the waste paper, is conveyed into the forming chamber 6. This eccentric, asymmetrical design of the namely, the lateral inlet opening is moved downward of the ram 4 and, if necessary, the shearing off of attached paper strips a torque on the press ram 4 exercised so that it is about its upright axis slightly twisted. This will ensure that the the underside of the ram 4 formed cutting edge 4a with each press stroke by a few degrees around the upright Ram axis is rotated further. This will make the Service life of the cutting edge 4a on the underside of the press ram 4 significantly increased. To this rotation of the ram 4 reach, there is a corresponding bearing on its upper side 4b is provided, around which the press ram 4 can rotate freely.

Es kann jedoch auf dieses Verdrehlager 4b auch verzichtet werden, da sich der dem Preßstempel 4 zugeordnete Preßkolben in dem Preßzylinder 5 ohnehin verdrehen kann. Es sei darauf hingewiesen, daß diese Bauart mit schrittweiser Verdrehung des Preßstempels aufgrund der asymmetrischen Gestaltung der Eintrittsöffnung von besonderer, eigenständiger Bedeutung ist und daher auch auf andere Kompaktierpressen Anwendung finden kann.However, this rotary bearing 4b can also be dispensed with be, since the ram 4 associated plunger in the press cylinder 5 can twist anyway. It was on it noted that this type with gradual rotation of the Press ram due to the asymmetrical design of the Entrance opening is of special, independent importance and can therefore also be used on other compacting presses can.

Im Zusammenhang mit Fig. 4 ist insbesondere noch auf die stabile Befestigung der beiden (hier schraffiert angedeuteten) seitlichen Platten zur Bildung des Schieberrahmens 14 hinzuweisen, die am massiv als ein Block ausgebildeten Gehäuse 31 der Formkammer 6 mit mehreren Schrauben angeflanscht sind (vgl. auch Fig. 2 entlang der Schnittlinie B-B) und somit eine besonders stabile Bauweise ergeben, zumal auch die weiteren Belastungsteile, nämlich die Zugstangen 32 und Schieberführung 10 daran befestigt bzw. ausgebildet sind.In connection with Fig. 4, in particular, the stable Attachment of the two (hatched here) side plates to form the slide frame 14th to point out the solidly designed as a block housing 31 of the molding chamber 6 are flanged with several screws (see also Fig. 2 along the section line B-B) and thus a result in particularly stable construction, especially since the others Load parts, namely the tie rods 32 and slide guide 10 are attached or formed thereon.

Die bezüglich der Zentralachse der Formkammer 6 asymmetrische Einlaßöffnung 7 ist hierbei durch die im rechten, unteren Bereich gegenüber der Kreisform radial erweiterten Außenform nockenförmig ausgebildet, wobei auch andere Formen möglich sind, z. B. eine außermittige Versetzung oder eine elliptische Form der Einlaßöffnung 7.The asymmetrical with respect to the central axis of the mold chamber 6 Inlet opening 7 is in this case in the lower right Area radially expanded from the circular shape cam-shaped, other shapes are also possible, e.g. B. an off-center offset or an elliptical shape the inlet opening 7.
