Abstract

A refuse packaging assembly of the kind comprising a refuse press having a pressing plunger which is axially movable in a pressing box, and a container which is adapted to be connected to the outlet end of the pressing box in order to be filled with refuse by the plunger, the container having a closure plug which is uncoupled from the container and coupled to the plunger for movement therewith when the container is connected to the press. The container carries at least one spring loaded pin which is biased into a coupling aperture in the closure plug to couple the two together, and the plunger carries at least one weaker spring loaded pin which aligns with the coupling aperture when the container is moved into position for connection to the press and the plunger is moved to a coupling position. A coupling lever which is operated by a power actuator to securely hold the container connected to the press simultaneously acts to retract the container pin from the coupling aperture, thereby uncoupling the plug from the container and allowing the plunger pin to move into the aperture to couple the plug to the plunger. Releasing the coupling lever automatically leads to uncoupling of the closure plug from the plunger and recoupling to the container.

Description

Die Erfindung betrifft eine Müllumschlaganlage mit einem an eine Müllpresse anzuschließenden und mit dieser zu füllenden Container, dessen eine Verschlußplatte tragende Öffnungsseite mit der Mündung des Preßkastens der Presse, in dem ein Preßstempel axial beweglich angeordnet ist, zu verbinden ist, wobei Verschlußplatte und Preßstempel über eine Vorrichtung zum Ver- und Entriegeln zu koppeln sind. Die mit dem Preßstempel gekoppelte Verschlußplatte des Containers wird während des Preßvorganges bzw. während des Befüllens des Containers als vorgeordnete Druckplatte mit dem Preßstempel verfahren.The invention relates to a waste handling system with a container to be connected to and filled with a garbage press, the opening side of which carries a closure plate and the mouth of the press box of the press, in which a ram is axially movable, is to be connected, the breech plate and ram being connected via a Device for locking and unlocking are to be coupled. The closure plate of the container coupled with the press ram is moved as an upstream pressure plate with the press ram during the pressing process or during the filling of the container.

Eine derartige Anlage ist aus der DE-PS 2 207 600 bekannt. Dabei wird das Abkoppeln der Verschlußplatte vom Container zu Beginn des Befüllvorganges, zwecks Übernahme durch den Preßstempel, sowie das Sichern und Verschließen des Containers mittels der Verschlußplatte vor dem Trennen des Containers von der Presse nach beendetem Befüllvorgang über einen anderen Antrieb gesteuert als das Ankoppeln der Verschlußplatte an den Preßstempel. Die bekannte Müllumschlaganlage benötigt somit für die Durchführung der vorangehend erwähnten Steuerfunktionen zwei unabhängig voneinander wirkende Antriebe.Such a system is known from DE-PS 2 207 600. The decoupling of the closure plate from the container at the beginning of the filling process for the purpose of being taken over by the press ram, and the securing and closing of the container by means of the closure plate before the container is separated from the press after the filling process has been completed, are controlled by a different drive than the coupling of the closure plate to the press ram. The known waste handling system therefore requires two independently acting drives to carry out the control functions mentioned above.

Nach Ansetzen des Containers an die Müllpresse gelangen bei der bekannten Anlage zunächst sogenannte Klinken, die in den Containerlängswänden angeordnet und über Ausziehfingerstäbe untereinander verbunden sind, in den Hubbereich von Schräglaufdornen. Die beidseitig der Presse angeordneten Schräglaufdorne werden dann durch einen Antrieb in Form eines Zylinders oder Elektro-Magneten, entgegen einer Federkraft, gegen die Ausziehfingerstäbe gedrückt, wodurch die Klinken, die in die an der Containerverschlußplatte angebrachten Rasten eingreifen, um diese am Container zu sichern, aus den Rasten ausfahren.After attaching the container to the garbage press in the known system, so-called pawls, which are arranged in the longitudinal walls of the container and are connected to one another via pull-out finger bars, reach the stroke area of the skewing mandrels. The diagonal mandrels arranged on both sides of the press are then pressed against the pull-out finger rods by a drive in the form of a cylinder or electro-magnet, against a spring force, as a result of which the pawls which engage in the catches attached to the container closure plate in order to secure them to the container extend from the notches.

Die freigegebene, vom Container gelöste Verschlußplatte wird sodann von dem vorgefahrenen Preßstempel übernommen. Die Übernahme bzw. Kopplung der Containerverschlußplatte mit dem Preßstempel erfolgt über einen weiteren Antriebsmechanismus, und zwar entweder über elektrische Haftmagnete oder über eine elektromechanische Verriegelung, die aufwendige Haken-, Zentrierdorn- und Klinkenanordnungen benötigt.The released closure plate released from the container is then taken over by the press die moved forward. The take-over or coupling of the container closure plate with the press ram is carried out via a further drive mechanism, either via electrical holding magnets or via an electromechanical locking mechanism, which requires complex hook, centering pin and latch arrangements.

Der Hauptnachteil einer derartigen Müllumschlaganlage ist der erhebliche bauliche Aufwand, der mit den beiden Kraftantrieben verbunden ist, die für den Anschluß des Containers an die Müllpresse und die Kopplung des Preßstempels mit der Verschlußplatte des Containers unbedingt erforderlich sind. Hinzu kommt, daß bei der Kopplung der Verschlußplatte des Containers mit dem Preßstempel die genaue Positionierung des aufnehmenden Preßstempels relativ zu den an der Verschlußplatte angebrachten Haken und Zentrierdornen sehr aufwendig ist. Dabei müssen die einzelnen Steuerfunktionen - Ankoppeln des Containers an die Presse und Übernahme der Verschlußplatte des Containers durch den Preßstempel sowie die damit verbundene Überwachung - von Bedienungspersonal eingeleitet bzw. durchgeführt werden. Die mit dem Einsatz des erforderlichen Bedienungspersonals verbundenen Personalkosten wirken sich für den Betreiber der Müllumschlaganlage in höchstem Maße unwirtschaftlich aus.The main disadvantage of such a waste handling system is the considerable structural effort which is associated with the two power drives, which are absolutely necessary for the connection of the container to the waste press and the coupling of the press ram to the closure plate of the container. In addition, when the closure plate of the container is coupled to the press die, the exact positioning of the receiving press die relative to the hooks and centering mandrels attached to the closure plate is very complex. The individual control functions - coupling the container to the press and taking over the closure plate of the container by the press ram and the associated monitoring - must be initiated or carried out by operating personnel. The personnel costs associated with the deployment of the necessary operating personnel have an extremely uneconomical impact on the operator of the waste handling system.

Sowohl durch die Anzahl der erforderlichen Antriebe und dem daraus resultierenden Aufwand in technischer Hinsicht, als auch die Anzahl der erforderlichen Funktionsabläufe während des An- bzw. Abkopplungsvorganges des Containers von der Presse ergeben eine unrationelle Arbeitsweise und lange Wechselzeiten beim Beladen der Container. Dadurch besitzt die bekannte Müllumschlaganlage letztendlich auch einen schlechten Wirkungsgrad, der durch das ungünstige Verhältnis der möglichen Leistungsfähigkeit der Müllpresse zum durch den zeitaufwendigen An- und Abkopplungsvorgang lediglich gewährleisteten tatsächlichen Müllumschlag pro Zeiteinheit bedingt ist.Both the number of drives required and the resulting technical effort, as well as the number of required functional sequences during the coupling and uncoupling process of the container from the press result in an inefficient method of operation and long changing times when loading the container. As a result, the known waste handling system ultimately also has a poor efficiency, which is due to the unfavorable ratio of the possible performance of the waste press to the actual waste handling per unit of time which is only guaranteed by the time-consuming coupling and uncoupling process.

Störungen können bei der bekannten Anlage außerdem dadurch verursacht werden, daß weder der Container noch die Presse zwangsläufig den Verriegelungsvorgang regelnde Einrichtungen bzw. Verriegelungselemente besitzt, die während des Befüllens des Containers diesen in Flucht mit der Müllpresse (Befüllposition) halten könnten.Faults in the known system can also be caused by the fact that neither the container nor the press inevitably has facilities or locking elements which regulate the locking process and which, during the filling of the container, could keep it in line with the refuse press (filling position).

Der Erfindung liegt daher die Aufgabe zugrunde, eine Müllumschlaganlage der eingangs genannten Art vorzuschlagen, die bei störunanfälligem Aufbau und minimalem Personalaufwand ein besonders schnelles und problemloses, der Leistungsfähigkeit der Presse optimal angepaßtes An- und Abkoppeln sowie Auswechseln von Containern ermöglicht.The invention is therefore based on the object of proposing a waste handling system of the type mentioned which, in the case of a structure which is not susceptible to faults and minimal personnel expenditure, enables a particularly fast and problem-free coupling and uncoupling and replacement of containers which is optimally adapted to the performance of the press.

Diese Aufgabe wird erfmdungsgemäß gelöst durch mindestens ein Paar zusammenwirkender, über einen gemeinsamen Kraftantrieb zu verbindender, je mit einem Rückstellelement in Wirkverbindung stehender Bolzen als Vorrichtung zum Ver- und Entriegeln, von denen jeweils ein Bolzen jedes Paares dem Preßstempel und der andere dem Container zugeordnet ist und beide unter gegensinnigen Kräften stehenden Bolzen in Koppelposition koaxial gegensinnig in eine Koppelbohrung der Verschlußplatte eingreifen können.This object is achieved according to the invention by at least one pair of interacting bolts, which are to be connected via a common power drive and are each operatively connected to a restoring element, as a device for locking and unlocking, one bolt of each pair being assigned to the press ram and the other to the container and both opposing bolts in the coupling position can engage coaxially in opposite directions in a coupling bore of the closure plate.

In überraschend einfacher Weise wird mit den erfindungsgemäßen Merkmalen erreicht, daß das Verbinden des Containers mit der Müllpresse ebenso funktionssicher und schnell wie das Ankoppeln der Verschlußplatte des Containers an den Preßstempel, über nur einen einzigen gemeinsamen Antrieb. gesteuert, vollautomatisch erfolgt.It is achieved in a surprisingly simple manner with the features according to the invention that the connection of the container to the garbage press is as reliable and fast as the coupling of the closure plate of the container to the press ram, via only a single common drive. controlled, fully automatic.

Ein zusätzlicher konstruktionsaufwendiger Antrieb, wie er bei der bekannten Anlage zum Durchführen der erwähnten Steuerfunktionen bzw. der An- und Abkopplungsvorgänge benötigt wird, ist bei der erfindungsgemäßen Müllumschlaganlage somit nicht erforderlich.An additional design-intensive drive, as in the known system for Performing the control functions mentioned or the coupling and decoupling processes is therefore not required in the waste handling system according to the invention.

Außerdem wird durch den einzigen dem Kopplungsvorgang zugeordneten gemeinsamen Antrieb eine funktionelle Verschmelzung der ineinandergreifenden Arbeitsabläufe - Kopplung des Containers mit der Presse und Übernahme der Verschlußplatte des Containers durch den Preßstempel - erreicht. Bedingt durch den vollautomatisch ablaufenden Vorgang bzw. das nacheinander erfolgende Auslösen der in funktioneller Abhängigkeit stehenden Bolzen und der damit verbundenen Maschinenelemente, entfällt die normalerweise für das Einleiten verschiedener Steuerfunktionen erforderliche manuelle Tätigkeit. Unnötige Wartezeiten beim Wechseln der Container, die z. B. durch unaufmerksames Bedienungspersonal verursacht werden können, werden bei der erfindungsgemäßen Müllumschlaganlage durch die Vollautomatisierung des Arbeitsablaufes zuverlässig verhindert.In addition, a functional fusion of the interlocking work processes - coupling the container to the press and taking over the closure plate of the container by the press ram - is achieved by the only joint drive assigned to the coupling process. Due to the fully automatic process or the successive triggering of the functionally dependent bolts and the associated machine elements, the manual work normally required to initiate various control functions is eliminated. Unnecessary waiting times when changing containers, e.g. B. can be caused by inattentive operating personnel are reliably prevented by the fully automated workflow in the waste handling system according to the invention.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Lehre sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the teaching according to the invention can be found in the subclaims.

Beim Anschließen des Containers an die Presse wird über den gemeinsamen Antrieb, mit dem die Bolzen in Verbindung stehen, zunächst das dem Container zugeordnete, federbelastete Rückstellelement aktiviert, d. h. daß der Bolzen, der die Verschlußplatte am Container sichert, aus der Bohrung in der Verschlußplatte des Containers zurückgezogen wird, um die Verschlußplatte für den nachfolgend automatisch ausgelösten Kopplungsvorgang des vorfahrenden Preßstempels mit der Verschlußplatte freizugeben. Vorteilhafterweise wirkt deshalb die Kraft der Feder des am Preßstempel befestigten Rückstellelementes gegensinnig zu der Kraft der Feder des am Container befestigten Rückstellelementes, wodurch gewährleistet wird, daß nach Rückzug des einen Bolzens aus der Bohrung der Verschlußplatte automatisch der durch das am Preßstempel befestigte Rückstellelement beaufschlagte Bolzen in die freigegebene Bohrung fährt, so daß die Verschlußplatte mit dem Preßstempel verbunden wird.When the container is connected to the press, the spring-loaded restoring element assigned to the container is first activated via the common drive with which the bolts are connected. H. that the bolt, which secures the closure plate to the container, is withdrawn from the hole in the closure plate of the container in order to release the closure plate for the subsequently automatically triggered coupling process of the preceding ram with the closure plate. Advantageously, therefore, the force of the spring of the restoring element fastened to the press ram acts in the opposite direction to the force of the spring of the restoring element fastened to the container, which ensures that, after the one bolt has withdrawn from the bore of the closure plate, the bolt acted upon by the restoring element fastened to the press ram automatically the released bore moves so that the closure plate is connected to the press ram.

Nach beendetem Befüllvorgang, vor dem Abkoppeln des Containers von der Presse wird der mit der Vorrichtung zum Ver- bzw. Entriegeln bzw. mit den Bolzen verbundene gemeinsame Antrieb abgeschaltet. Damit nachfolgend zum Verschließen des Containers mit der Verschlußplatte die Verschlußplatte vom Preßstempel automatisch gelöst werden kann, ist in Ausgestaltung der Erfindung die Kraft der Feder des am Container befestigten Rückstellelementes größer als die Kraft der Feder des am Preßstempel befestigten Rückstellelementes. Auf diese Weise kann der dem Container zugeordnete Bolzen den zu diesem Zeitpunkt in der Bohrung der Verschlußplatte befindlichen Bolzen soweit zurückdrängen, daß der Container mit der durch den Bolzen daran gesicherten Verschlußplatte abtransportiert werden kann.After the filling process has ended, before uncoupling the container from the press, the common drive connected to the locking and unlocking device or to the bolts is switched off. So that subsequently to close the container with the closure plate, the closure plate can be released from the press ram, in an embodiment of the invention the force of the spring of the restoring element fastened to the container is greater than the force of the spring of the restoring element fastened to the press ram. In this way, the pin assigned to the container can push back the pin located at the time in the bore of the locking plate to such an extent that the container can be transported away with the locking plate secured to it by the pin.

Beim Anschließen des Containers an die Presse stellt der zu diesem Zeitpunkt von der Kraft der Feder des Rückstellelementes beaufschlagte Bolzen, der aus dem Preßstempel herausragt, ein zu überwindendes Hindernis dar. In weiterer Ausgestaltung der Erfindung weist deshalb die dem Preßstempel zugewandte Fläche der Verschlußplattenseitenwand eine abgeschrägte Auflauffläche auf. Durch diese Ausgestaltung der Seitenwand der Verschlußplatte wird erreicht, daß bei Auftreffen der Auflauffläche auf das vorstehende Bolzenelement durch den stetig weiter vorfahrenden Container der Bolzen entgegen der Kraft der Feder nachgibt und dem Verlauf der Auflauffläche folgt, um nachfolgend nach Betätigung des Kopplungshebels und Kopplung des Containers mit der Presse in die Bohrung in der Verschlußplatte des Containers einzurasten.When the container is connected to the press, the bolt, which at this point is acted upon by the force of the spring of the restoring element and protrudes from the press ram, represents an obstacle to be overcome. In a further embodiment of the invention, the surface of the closure plate side wall facing the press ram therefore has a beveled surface Ramp area. This configuration of the side wall of the closure plate ensures that when the run-up surface hits the protruding bolt element, the bolt yields against the force of the spring due to the continuously advancing container and follows the course of the run-up surface, in order to subsequently operate the coupling lever and couple the container with the press into the hole in the closure plate of the container.

Details of the invention are described below with reference to the drawings, in which a preferred exemplary embodiment is shown. Show it :
  • 1 shows a waste handling system in a side view in section, along the line II in FIG. 2 with a container coupled to a press and a closure plate fastened to the press ram;

Zu der Müllumschlaganlage gehört eine Presse 1 und ein in Bewegungsrichtung oder Preßrichtung eines Stempels 2 sich anschließender, mit der Presse koppelbarer Container 3. Die Müllpresse 1 besteht aus einem horizontalen Preßkasten 4, in dem sich der Preßstempel 2 bewegt und der an der dem Container 2 zugewandten Seite durch eine vertikal verschiebbare Platte 5 für den Fall verschließbar ist, daß Gut vorgepreßt werden soll. Durch einen hydraulischen Zylinder-Kolbenantrieb 6 kann die Platte 5 auf- und niedergefahren werden. In Fig. 1 ist sie in hochgefahrener Stellung gezeigt. In niedergefahrener Stellung verschließt die Platte 5 den Preßkasten 4. Durch das Verpressen des Materials gegen die Platte 5 wird die Materialdichte im Container, in den das verpreßte Material anschließend eingeschoben wird, unabhängig von der wechselnden Zusammensetzung des Mülls, erheblich erhöht. Werden an die Dichte geringere Anforderungen gestellt, so ist es auch möglich, anstatt gegen die Platte 5, das Material direkt in den Container einzupressen. In den Preßkasten 4 mündet von oben ein Füllschacht 7, durch den das zu verpressende Material eingebracht wird. Der durch einen weiteren hydraulischen Zylinder-Kolbenantrieb 8 zu betätigende Stempel 2 hat sowohl als Förderstempel als auch als Preßstempel zu arbeiten.The waste handling system includes a press 1 and a container 3 which is connected in the direction of movement or pressing direction of a stamp 2 and can be coupled to the press. The waste press 1 consists of a horizontal press box 4 in which the press stamp 2 moves and which on the container 2 facing side can be closed by a vertically displaceable plate 5 in the event that good is to be pre-pressed. The plate 5 can be moved up and down by a hydraulic cylinder-piston drive 6. In Fig. 1 it is shown in the raised position. In the lowered position, the plate 5 closes the press box 4. By compressing the material against the plate 5, the material density in the container, into which the pressed material is then inserted, is considerably increased, regardless of the changing composition of the waste. If lower demands are placed on the density, it is also possible to press the material directly into the container instead of against the plate 5. In the press box 4, a filling chute 7 opens from above, through which the material to be pressed is introduced. The punch 2 to be actuated by a further hydraulic cylinder-piston drive 8 has to work both as a conveying punch and as a pressing punch.

Es sei an dieser Stelle erwähnt, daß in praktischer Ausführung zu beiden Seiten des Containers 3 und der Presse 1 sowie des Preßstempels 2 je eine Vorrichtung 9 zum Ver- und Entriegeln angebracht ist, die nachfolgend noch näher erläutert wird. Der Einfachheit halber wird die Erfindung hier jedoch nur am Beispiel einer Container-Pressen- oder Preßstempelseite erläutert.At this point it should be mentioned that in a practical version on both sides of the Contai Ners 3 and the press 1 and the press ram 2 a device 9 for locking and unlocking is attached, which will be explained in more detail below. For the sake of simplicity, however, the invention is only explained here using the example of a container press or ram side.

Die Vorrichtung 9 zum Ver- und Entriegeln ist im dargestellten Ausführungsbeispiel teilweise in einer Containertür 10 und teilweise im Preßstempel 2 angeordnet. Anstatt in der Containertür 10 wäre aber auch eine Anordnung der Vorrichtung 9 zum Ver- und Entriegeln in der Containerlängswand, bzw. im Boden oder in der Decke des Containers denkbar. Der im Preßstempel 2 untergebrachte Teil der Vorrichtung 9 zum Ver- und Entriegeln besteht aus einem Bolzen 11, der mit einem federbelasteten Rückstellelement 12 in Wirkverbindung steht. Bei den dargestellten Ausführungsbeispielen handelt es sich um eine mechanische Feder F" unter deren Wirkung das Rückstellelement 12 steht. Der Einsatz gleichwertiger Mittel bezüglich der zum Einsatz kommenden Rückstellelemente an der Preßstempel- und Containerseite ist ohne weiteres möglich. Jeweils in der Containertür 10 und im Preßstempel 2 senkrecht übereinander angeordnete Vorrichtungen 9 zum Ver- und Entriegeln bzw. die entsprechenden Bolzenelemente 11 und 14 stehen über einen nicht dargestellten Hebelmechanismus miteinander in Verbindung, der an der Müllpresse 1 befestigt ist. Durch den Hebelmechanismus wird gewährleistet, daß die übereinander angeordneten Vorrichtungen 9 zum Ver- und Entriegeln identische Betätigung erfahren. Vor Beginn des Ankopplungsvorganges ist das Rückstellelement 12 entspannt, und der dem Preßstempel 2 zugeordnete Bolzen 11 ragt aus der Seitenwand 2a des Preßstempels 2 heraus, wie in Fig. 3a dargestellt.In the exemplary embodiment shown, the device 9 for locking and unlocking is partly arranged in a container door 10 and partly in the press ram 2. Instead of in the container door 10, an arrangement of the device 9 for locking and unlocking in the longitudinal container wall, or in the floor or in the ceiling of the container would also be conceivable. The part of the device 9 for locking and unlocking accommodated in the press die 2 consists of a bolt 11 which is in operative connection with a spring-loaded restoring element 12. In the exemplary embodiments shown, it is a mechanical spring F ″ under whose action the restoring element 12 stands. The use of equivalent means with regard to the restoring elements used on the press ram and container side is readily possible. In each case in the container door 10 and in the press ram 2 devices 9 for locking and unlocking arranged vertically one above the other or the corresponding bolt elements 11 and 14 are connected to one another via a lever mechanism, not shown, which is fastened to the garbage press 1. The lever mechanism ensures that the devices 9 arranged one above the other for Before the start of the coupling process, the restoring element 12 is relaxed, and the pin 11 assigned to the press die 2 protrudes from the side wall 2a of the press die 2, as shown in FIG. 3a.

Vor der Ausstoßöffnung der Presse 1 befindet sich in Flucht mit dieser ein Container 3, der mit einer Verschlußplatte 13 versehen ist. Die Verschlußplatte 13 ist am Container 3 über einen Bolzen 14 gesichert, der in zwei miteinander fluchtende, in der Containertür 10 und in der Verschlußplatte 13 angeordnete Bohrungen 15, 16 eingreift. Die Bohrung 16 in der Verschlußplatte 13 wird im Rahmen der Erfindung auch als « Koppelbohrung » bezeichnet, da sie wahlweise jedem Bolzen des jeweiligen Bolzenpaares als Aufnahme zum Koppeln der Verschlußplatte 13 entweder am Preßstempel 2 oder am Container 3 dient. Der dem Container 3 zugeordnete Bolzen 14 steht in Wirkverbindung mit einem federbelasteten, und zwar hier von einer mechanischen Feder F2 beaufschlagten Rückstellelement 17. Die mechanische Feder F2 ist im von der Presse 1 abgekoppelten Zustand des Containers entspannt. Die Kräfte der auf die Rückstellelemente 12 und 17 wirkenden Federn F" F2 wirken gegensinnig, außerdem ist die Kraft der Feder F2 des dem Container 2 zugeordneten Rückstellelementes 17 größer als die Kraft der Feder F, des dem Preßstempel zugeordneten Rückstellelementes 12. Beide Bolzen 11 und 14, die dem Preßstempel 2 bzw. dem Container 3 zugeordnet sind, stehen über einen gemeinsamen Kraftantrieb 18, der beispielsweise an der Presse 1 befestigt ist, in Verbindung. Der Kraftantrieb 18 wirkt auf einen Kopplungshebel 19, der um eine an der Presse 1 befestigte Schwenkachse 20 schwenkbeweglich gelagert ist.In front of the discharge opening of the press 1 there is a container 3 which is provided with a closure plate 13. The closure plate 13 is secured to the container 3 by a bolt 14 which engages in two mutually aligned bores 15, 16 arranged in the container door 10 and in the closure plate 13. The bore 16 in the closure plate 13 is also referred to in the context of the invention as a “coupling bore”, since it optionally serves as a receptacle for coupling the closure plate 13 either to the press ram 2 or to the container 3 for each bolt of the respective pair of bolts. The bolt 14 assigned to the container 3 is operatively connected to a spring-loaded restoring element 17, namely a mechanical spring F 2 here. The mechanical spring F 2 is relaxed when the container is uncoupled from the press 1. The forces of the springs F "F 2 acting on the restoring elements 12 and 17 act in opposite directions; moreover, the force of the spring F 2 of the restoring element 17 associated with the container 2 is greater than the force of the spring F, of the restoring element 12 associated with the press ram 12. Both bolts 11 and 14, which are assigned to the press ram 2 and the container 3, are connected via a common power drive 18, which is fastened, for example, to the press 1. The power drive 18 acts on a coupling lever 19, which is attached to the press 1 attached pivot axis 20 is pivotally mounted.

Bei an die Presse 1 angekoppeltem Container 3 greift der Kopplungshebel 19 in eine am Container 3 vorhandene Nische 21 ein, so daß der Container 3 gesichert in der Befüllposition gehalten werden kann.When the container 3 is coupled to the press 1, the coupling lever 19 engages in a niche 21 provided on the container 3, so that the container 3 can be securely held in the filling position.

Am Kopplungshebel 19 ist im Abstand der Schwenkachse 20 ein Druckstück 22 angeordnet, das, wie nachfolgend noch näher erläutert werden wird, im an die Presse 1 angekoppelten Zustand des Containers 3 auf einen Hebel 23 wirkt, bzw. diesen niederdrückt, welcher an dem dem Container 3 zugeordneten Bolzenelement 14 befestigt istOn the coupling lever 19, a pressure piece 22 is arranged at a distance from the pivot axis 20, which, as will be explained in more detail below, acts on the lever 1 when the container 3 is coupled to a lever 23, or depresses it, which on the container 3 associated bolt member 14 is attached

Die um 90° abgewinkelte Seitenwand 24 der Verschlußplatte 13 des Containers besitzt an ihrer dem dem Preßstempel 2 zugeordneten Bolzen 11 zugewandten Fläche 24a eine abgeschrägte Ablauffläche 25, die, wie nachfolgend noch erläutert, für das Einrasten des in einer Bohrung 26 im Preßstempel 2 geführten Bolzens 11 in die Bohrung 16 der Verschlußplatte 13 des Containers von Bedeutung ist.The side wall 24 of the closure plate 13 of the container, which is angled by 90 °, has on its surface 24a facing the pin 11 assigned to the press ram 2 a beveled run-off surface 25 which, as will be explained below, for snapping the pin guided in a bore 26 in the press ram 2 11 in the bore 16 of the closure plate 13 of the container is important.

Die Arbeitsweise der vorbeschriebenen erfindungsgemäßen Müllumschlaganlage wird nachfolgend anhand der Ausführungsform gemäß den Fig. 3a bis 3c näher erläutert: Vor Beginn des Ankopplungsvorganges des Containers 3 an die Presse 1 wird der Preßstempel 2 bis in eine Stellung vorgefahren (s. u. a. Fig. 3a), in der nachfolgend eine Kopplung der Verschlußplatte 13 des Containers mit dem Preßstempel 2 stattfinden kann. Sodann wird der Container 3 an die Presse 1 herangefahren ; dabei trifft gemäß Fig. 3a die abgeschrägte Ablauffläche 25 der Verschlußplatte 13 des Containers auf den aus dem Preßstempel 2 herausragenden Bolzen 11. Durch weiteres Heranfahren des Containers 3 an die Presse 1 folgt das Bolzenelement 11 der abgeschrägten Ablauffläche 25, entgegen der Kraft der Feder F1 des dem Preßstempel 2 zugeordneten Rückstellelementes 12. Die Feder F1 wird durch den heranfahrenden Container 3 kontinuierlich gespannt. Der Container 3 wird soweit vorgefahren, bis die quer zur Bewegungsrichtung P des Preßstempels 2 liegenden Bohrungen 15, 16, 26 - in der Containertür, in der Verschlußplatte bzw. im Preßstempel - miteinander fluchten, wie in Figur 3b dargestellt.The operation of the above-described refuse handling system according to the invention is explained in more detail below with reference to the embodiment according to FIGS. 3a to 3c: Before the coupling process of the container 3 to the press 1 begins, the press ram 2 is moved into a position (see FIG. 3a) in which subsequently a coupling of the closure plate 13 of the container with the press ram 2 can take place. The container 3 is then moved up to the press 1; 3a, the beveled drainage surface 25 of the closure plate 13 of the container meets the pin 11 protruding from the press ram 2. By moving the container 3 closer to the press 1, the bolt element 11 of the beveled drainage surface 25 follows, counter to the force of the spring F. 1 of the restoring element 12 assigned to the press ram 2. The spring F 1 is continuously tensioned by the approaching container 3. The container 3 is advanced until the bores 15, 16, 26 lying transversely to the direction of movement P of the press die 2 — in the container door, in the closure plate or in the press die — are aligned with one another, as shown in FIG. 3b.

Der Bolzen 14, der dem Container 3 zugeordnet ist und die Verschlußplatte 13 am Container 3 sichert, drückt durch eine gegensinnig wirkende, entspannte Feder F2, gemäß Fig. 3c, den dem Preßstempel 2 zugeordneten Bolzen 11 nieder bzw. hält die Feder F1 gespannt, die auf den dem Preßstempel zugeordneten Bolzen 11 wirkt. Nach Anstellen des Containers 3 an die Presse 1 (Fig. 3b) schwenkt der Kopplungshebel von der in Fig. 3a in die in Fig. 3b dargestellte Stellung. Durch diesen Vorgang wird gleichzeitig einerseitsThe bolt 14, which is assigned to the container 3 and secures the closure plate 13 on the container 3, presses down by a counter-acting, relaxed spring F 2 , according to FIG. 3c, the bolt 11 assigned to the press ram 2 or keeps the spring F1 tensioned which acts on the pin 11 assigned to the press ram. After the container 3 has been placed against the press 1 (FIG. 3b), the coupling lever pivots from the position in FIG. 3a to the position shown in FIG. 3b. Through this process, on the one hand

der Container 3 mit der Presse 1 gekoppelt und andererseits kommt das am Kopplungshebel 19 befestigte Druckstück 22 mit dem Hebel 23 in Kontakt, wodurch die Feder F2 gespannt und der Bolzen 14 aus der Bohrung 15 der Verschlußplatte 13 zurückgezogen wird, dadurch wird nachfolgend automatisch der dem Preßstempel 2 zugeordnete Bolzen 11 kontinuierlich unter der Wirkung der ihn beaufschlagenden Feder F, in die Koppelbohrung 16 der Verschlußplatte geschoben. In diesem Zustand ist der Container 3 mit der Müllpresse 1 fest verbunden, während der Preßstempel 2 nun mit der Verschlußplatte 13 des Containers 3 gekoppelt ist, die nachfolgend während des Befüllens des Containers und auch während des Preßvorganges als vorgeordnete Druckplatte mit dem Preßstempel 2 bewegt wird.the container 3 is coupled to the press 1 and, on the other hand, the pressure piece 22 fastened to the coupling lever 19 comes into contact with the lever 23, as a result of which the spring F 2 is tensioned and the bolt 14 is withdrawn from the bore 15 of the closure plate 13, as a result of which the the plunger 2 associated bolt 11 continuously pushed into the coupling bore 16 of the closure plate under the action of the spring F acting on it. In this state, the container 3 is firmly connected to the garbage press 1, while the press ram 2 is now coupled to the closure plate 13 of the container 3, which is subsequently moved with the press ram 2 during the filling of the container and also during the pressing process as an upstream pressure plate .

Technisch wäre es im Rahmen des Erfindungsgedankens auch möglich, die Kinematik der vorangehend beschriebenen, erfindungsgemäßen Vorrichtung, bzw. des Kopplungsablaufes umzukehren, indem man die Kraft der Feder F, des dem Preßstempel 2 zugeordneten Rückstellelementes 12 größer auslegt als die Kraft der Feder F2 des dem Container 3 zugeordneten Rückstellelementes 17. Die Rückstellung des dem Container 3 zugeordneten Rückstellelementes 17 - bzw. die Kopplung der Verschlußplatte 13 mit dem Container 3 - aus der in Fig. 3b in die in Fig. 3c dargestellte Stellung könnte beispielsweise auch über eine durch den Hebel 23 über den gemeinsamen Antrieb 18 zu spannende zwischengeschaltete Rückstellfeder (nicht gezeichnet) erreicht werden, die unter Ausnutzung der im Hebel 23 liegenden Übersetzung die Feder F, zusammenzudrücken vermag.Technically, it would also be possible within the scope of the inventive concept to reverse the kinematics of the device according to the invention described above, or of the coupling process, by designing the force of the spring F, the restoring element 12 assigned to the press ram 2, to be greater than the force of the spring F 2 of the the return element 17 assigned to the container 3. The return of the return element 17 assigned to the container 3 - or the coupling of the closure plate 13 to the container 3 - from the position shown in FIG. 3b to the position in FIG Lever 23 via the common drive 18 to be interposed intermediate return spring (not shown) can be reached, which is able to compress the spring F using the ratio lying in the lever 23.

Denkbar wäre aber auch die weniger effektive Verfahrensmöglichkeit, bei der der Container 3 an die Presse 1 angestellt wird und der Preßstempel 2 sodann bis in die Preßendstellung vorgefahren wird. Der aus dem Preßstempel 2 herausragende Bolzen 11 würde ebenfalls auf die abgeschrägte Ablauffläche 25 der Seitenwand 24 der Verschlußplatte 13 auftreffen und deren Verlauf folgen, wodurch er entgegen der Kraft der Feder F, ausgelenkt und in den Preßstempel 2 hineingedrückt würde. Sobald der Preßstempel 2 seine Endstellung erreicht hat, wie in Fig. 3b dargestellt, fluchten die quer zur Bewegungsrichtung P verlaufenden Bohrungen 15, 16, 26, und die Müllpresse 1 wird über den an ihr befestigten Kopplungshebel 19 an den Container 3 angekoppelt, wodurch dann der dem Container 3 zugeordnete Bolzen 14 über den vorangehend erläuterten Mechanismus aus der Bohrung 16 der Verschlußplatte 13 des Containers zurückgezogen wird (s. Fig. 3b). Der weitere Ablauf erfolgt dann ebenfalls wie zuvor beschrieben. Nach beendetem Befüllen des Containers wird der Kopplungshebel 19 gelöst, wodurch das dem Container 3 zugeordnete Rückstellelement 17 bzw. die Feder F2 expandiert und dementsprechend der Bolzen 14 in die Bohrung 16 der Verschlußplatte des Containers einfährt. Durch die größere Kraft der Feder F2 wird der in die Bohrung 16 der Verschlußplatte 13 eingreifende, dem Preßstempel 2 zugeordnete Bolzen 11 vollkommen zurückgeschoben, so daß der Verbund zwischen Preßstempel 2 und Verschlußplatte 13 gelöst und der Container 3 wieder mit der Verschlußplatte 13 verschlossen ist (s. Fig. 3c). Der befüllte, von der Presse abgekoppelte Container 3 kann sodann abtransportiert und ein neuer Container an die Presse angeschlossen werden.However, the less effective method would also be conceivable, in which the container 3 is placed against the press 1 and the press ram 2 is then advanced to the final press position. The pin 11 protruding from the press die 2 would also strike the beveled run-off surface 25 of the side wall 24 of the closure plate 13 and follow its course, as a result of which it would be deflected against the force of the spring F and pressed into the press die 2. As soon as the press ram 2 has reached its end position, as shown in FIG. 3b, the bores 15, 16, 26, which run transversely to the direction of movement P, are aligned, and the garbage press 1 is coupled to the container 3 via the coupling lever 19 attached to it, which then the bolt 14 assigned to the container 3 is withdrawn from the bore 16 of the closure plate 13 of the container via the mechanism explained above (see FIG. 3b). The rest of the process then also takes place as previously described. After the container has been filled, the coupling lever 19 is released, as a result of which the restoring element 17 assigned to the container 3 or the spring F 2 expands and accordingly the bolt 14 moves into the bore 16 of the closure plate of the container. Due to the greater force of the spring F 2 , the pin 11 engaging in the bore 16 of the closure plate 13 and assigned to the press ram 2 is pushed back completely, so that the connection between the press ram 2 and the closure plate 13 is released and the container 3 is closed again with the closure plate 13 (see Fig. 3c). The filled container 3, uncoupled from the press, can then be removed and a new container connected to the press.
