Description

Die Erfindung betrifft eine Schutzvorrichtung für eine Hubkipp-oder Kippvorrichtung zum Entleeren von Behältern in die Einschüttöffnung eines Sammelbehälters, insbesondere eines Müllsammelfährzeuges.The invention relates to a protective device for a lifting and tipping device for emptying containers into the pouring opening of a collecting container, in particular a refuse collection vehicle.

Aus DE 34 05 997 A1 ist eine Vorrichtung zum Entleeren von Behältern in einen Sammelbehälter, insbesondere zum Entleeren von Müllbehältern in ein Müllsammelfahrzeug, bekannt, die mit einer Schutzvorrichtung für die in dieser Vorrichtung zum Entleeren der Behälter vorgesehene Kippvorrichtung oder Hubkippvorrichtung ausgestattet ist. Bei dieser bekannten Vorrichtung ist die Schutzvorrichtung als Barriere ausgebildet, die zwei in horizontaler Wirkstellung und in eine im wesentlichen vertikale Ruhestellung schwenkbare Barrierearme enthält. Diese Barrierearme stellen eine seitliche Abgrenzung des Arbeitsbereiches der Kippvorrichtung bzw. Hubkippvorrichtung dar, und zwar jeweils ein Barrierearm zu jeder Seite. Diese Barriere dient in erster Linie dazu, daß unbeteiligte Dritte daran gehindert werden, während des Betriebs der Entleervorrichtung unbewußt in den Arbeitsbereich der Hubkippvorrichtung bzw. Kippvorrichtung zu laufen. Im übrigen läßt diese Barriere aber den Arbeitsbereich der Hubkippvorrichtung bzw. Kippvorrichtung frei, so daß beim Entleeren von Behältern eventuell herabfallende Teile und beim Entleeren von Behältern entstehender Staub praktisch ungehindert in die Umgebung gelangen können.DE 34 05 997 A1 discloses a device for emptying containers into a collecting container, in particular for emptying garbage containers into a refuse collection vehicle, which is equipped with a protective device for the tilting device or lifting and tilting device provided in this device for emptying the containers. In this known device, the protective device is designed as a barrier which contains two barrier arms which can be pivoted in the horizontal active position and in an essentially vertical rest position. These barrier arms represent a lateral delimitation of the working area of the tilting device or lifting and tilting device, specifically one barrier arm on each side. This barrier serves primarily to prevent uninvolved third parties from unconsciously running into the working area of the lifting / tipping device or tipping device during operation of the emptying device. In addition, this barrier leaves the working area of the lifting and tipping device free, so that parts falling down when emptying containers and dust arising when emptying containers are practical can reach the surroundings unhindered.

Entleervorrichtungen für Behälter, die im allgemeinen mit Hubkippvorrichtung oder Kippvorrichtung ausgestattet sind, und auch als Einschüttvorrichtung oder Schüttvorrichtung bezeichnet werden, sind in den unterschiedlichsten Ausführungen bekannt. In der Regel handelt est sich dabei um Vorrichtungen mit Schwenkarmen, in welche sich die zu entleerenden Behälter einhängen lassen oder um solche Vorrichtungen, deren Schwenkarme mit einem zusätzlichen Hubwagen über Gelenkführung verbunden sind. Bei diesen bekannten Entleervorrichtungen wird der zu entleerende Behälter zunächst von einer Aufnahme am Hubwagen erfaßt, dann gehoben und über das Verschwenken der Schwenkarme in die Einschüttöffnung des Sammelbehälters entleert.A wide variety of designs are known for emptying devices for containers, which are generally equipped with a lifting and tipping device or a tipping device and are also referred to as pouring devices or pouring devices. As a rule, these are devices with swivel arms, in which the containers to be emptied can be hung, or devices whose swivel arms are connected to an additional lifting carriage via an articulated guide. In these known emptying devices, the container to be emptied is first gripped by a receptacle on the lifting truck, then lifted and emptied into the pouring opening of the collecting container by pivoting the swivel arms.

Es sind auch Einschüttvorrichtungen bekannt, die lediglich über einen Hubwagen den Behälter entleeren. Bei diesen Vorrichtungen wird der Hubwagen über Schlitten- oder Rollenführungen zur Einschüttöffnung hin senkrecht angehoben und über Kurvenbahnen oder Gelenkhebel zu einer Schwenkbewegung gezwungen, mit der die Behälter in die Einschüttöffnung entleert werden.Dispensing devices are also known which only empty the container via a lifting truck. In these devices, the pallet truck is lifted vertically towards the pouring opening via slide or roller guides and is forced to pivot by cam tracks or articulated levers with which the containers are emptied into the pouring opening.

Diese Entleervorrichtungen werden im allgemeinen hydraulisch, gegebenenfalls auch pneumatisch angetrieben. Die Entleervorrichtung nach DE 34 05 997 ist darüberhinaus auch noch mit einer automatischen Antriebssteuerung ausgestattet, bei der mit dem Anbringen des zu entleerenden Behälters am Hubwagen ein Schalter geschlossen wird, der die automatische Steuerung des Entleervorganges in Gang setzt. Die als Barriere ausgebildete Schutzvorrichtung is dabei ebenfalls mit einem Schalter versehen, der in den Schaltungskreis der automatischen Steuerung eingreift und Einleitung und Druchführung des Entleervorganges nur zuläßt, wenn der durch Schließen der als Schutzvorrichtung dienenden Barriere eingeschaltet ist.These emptying devices are generally driven hydraulically, optionally also pneumatically. The emptying device according to DE 34 05 997 is also also equipped with an automatic drive control, in which a switch is closed when the container to be emptied is attached to the pallet truck, which initiates the automatic control of the emptying process. The protective device designed as a barrier is also provided with a switch which intervenes in the circuit of the automatic control and only allows the emptying process to be initiated and carried out when the barrier serving as the protective device is switched on.

Bei Anwendung der Entleervorrichtungen zum Entleeren von Müllbehältern in Müllsammelwagen kommt insbesondere störend eventuelle Staubentwicklung und Lärmentwicklung hinzu. Bei Entleervorrichtungen für Müllbehälter ist es deshalb auch bereits bekannt, daß die Einschüttöffnung für die Müllbehälter mit Staubtüchern abgedeckt ist, die die Einschüttöffnung mehr oder weniger abdichten, um den beim Einschütten der Behälter auftretenden Staub nicht übermäßig austreten zu lassen. Es sind auch Sammelbehälter mit einer gehäuseartigen Einschüttöffnung im Gebrauch, bei welchen die Behälter zunächst gegen eine Frontplatte in der Einschüttöffnung gekippt und dann mit dieser gemeinsam eingeschwenkt werden.When using the emptying devices for emptying garbage containers in garbage collection trolleys, there is in particular disruptive potential dust generation and noise. In emptying devices for refuse containers, it is therefore also known that the pouring opening for the refuse containers is covered with dusters that more or less seal the pouring opening in order not to let the dust that occurs when the containers are poured in excessively escape. Collection containers with a housing-like pouring opening are also used, in which the containers are first tilted against a front plate in the pouring opening and then pivoted in together with the latter.

Im Betrieb dieser Einschüttvorrichtungen steht in der Regel eine Bedienungsperson während des Entleervorganges in unmittelbarer Nähe der Vorrichtung bzw. der Einschüttöffnung des Sammelbehälters und ist dem austretenden Staub und dem durch das Einschütten der Behälter auftretenden Lärm sowie der durch den Bewegungsablauf entstehenden Gefahr direkt ausgesetzt. Die durch Staub, Lärm und mechanische Bewegung auftretenden Belästigungen und Gefahren betreffen außer dem Bedienungspersonal aber auch unbeteiligte Dritte, die sich in der Nähe befinden, und überhaupt die gesamte Umwelt.In the operation of these pouring devices, an operator is usually in the immediate vicinity of the device or the pouring opening of the collecting container during the emptying process and is directly exposed to the escaping dust and the noise caused by the pouring in of the containers as well as to the danger arising from the movement sequence. The nuisance and dangers caused by dust, noise and mechanical movement affect not only the operating personnel but also uninvolved third parties who are nearby and the entire environment in general.

In der DE-A-33 32 058 wird gefordert, zur möglichst staubfreien und unfallsicheren Entleerung die Greif-, Hub- und Kippvorrichtung im abschirmten Entleerungsraum arbeiten zu lassen. Es findet sich jedoch kein Hinweis, wie die Abschirmung zur Erfüllung dieser Forderung ausgebildet sein soll.DE-A-33 32 058 calls for the gripping, lifting and tilting device to work in the shielded emptying area for the most dust-free and accident-proof emptying. However, there is no indication of how the shielding should be designed to meet this requirement.

Es ist daher Aufgabe der Erfindung, eine verbesserte Schutzvorrichtung zu schaffen, die das Zusammenwirken von Einschüttvorrichtungen mit den Einschüttöffnungen von Sammelbehältern im Bezug auf Verminderung von Staub- und Lärmbelästigung sowie in Bezug auf Erhöhung der Sicherheit für Bedienungspersonal und unbeteiligte Dritte insgesamt verbessert.It is therefore an object of the invention to provide an improved protective device which improves the interaction of pouring devices with the pouring openings of collecting containers with regard to the reduction of dust and noise pollution and with regard to increasing safety for operating personnel and uninvolved third parties as a whole.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Einschüttöffnung des Sammelbehälters mit einer Abschirmung versehen ist, die den Arbeitsbereich der Hubkipp- oder Kippvorrichtung haubenartig ummantelt und aus Teilen gebildet ist, die zusammen und/oder getrennt beweglich angeordnet sind.This object is achieved in that the pouring opening of the collecting container is provided with a shield which encases the working area of the lifting and tipping device in a hood-like manner and is formed from parts which are arranged to be movable together and / or separately.

Durch die Erfindung wird erreicht, daß der gesamte Arbeitsbereich, der während des Einschüttvorganges von der Hubkippvorrichtung und dem angehängten Behälter durch den Bewegungsablauf benutzt wird, wie in einer Kapsel völlig abgeschirmt ist. Da die Abschirmung die Einschüttöffnung des jeweiligen Sammelbehälters mit einschließt, ist sichergestellt, daß ein wesentlicher Staubaustritt nicht stattfindet und der sonst übliche Lärmpegel, hervorgerufen durch Behältergeräusche, Hydraulikmotoren und Vorrichtungsbewegung, erheblich gesenkt wird. Durch die Abschirmung des Areitsbereiches der Einschüttvorrichtung wird aber auch gleichzeitg das Unfallrisiko eingeschränkt, denn es ist dem Bedienungspersonal nicht mehr möglich, während des Einschüttvorganges in den Arbeitsbereich zu gelangen.It is achieved by the invention that the entire working area, which is used during the pouring process by the lifting and tipping device and the attached container by the sequence of movements, is completely shielded in a capsule. Since the shield includes the pouring opening of the respective collecting container, it is ensured that a substantial dust escape does not take place and the otherwise usual noise level, caused by container noise, hydraulic motors and device movement, is considerably reduced. By the shielding of the area of the pouring device is also limited at the same time the risk of accidents, since it is no longer possible for the operating personnel to get into the work area during the pouring process.

Die bewegliche Anordnung der Teile hat den Vorteil, daß je nach Anordnung der Abschirmung an dem Sammelbehälter ein Wandteil für die Zuführung der Behälter an die Einschüttvorrichtung geöffnet bleiben kann, während die übrigen Wandteile bereits geschlossen sind. Dadurch ist einerseits unbeteiligten Personen schon während der Zeit, in welcher die Behälter zur Einschüttvorrichtung gebracht werden, der Zutritt zum Arbeitsbereich der Vorrichtung verwehrt. Andererseits bedeutet das Schließen eines einzigen Wandteiles vor Beginn der Einschüttbewegung einen wesentlich geringeren Zeitaufwand gegenüber der Schließ- und Öffnungsbewegung der gesamten Abschirmung.The movable arrangement of the parts has the advantage that, depending on the arrangement of the shield on the collecting container, a wall part for the supply of the containers to the pouring device can remain open while the other wall parts are already closed. As a result, on the one hand, uninvolved people are denied access to the working area of the device while the containers are being brought to the pouring device. On the other hand, the closing of a single wall part before the start of the pouring-in movement means a significantly shorter expenditure of time compared to the closing and opening movement of the entire shield.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die die Abschirmung bildenden Wandteile über Führungsschienen beweglich mit dem Sammelbehälter verbunden sind. Diese Maßnahme ist deshalb von Vorteil, weil mit den Einschüttvorrichtungen unterschiedlich große Behälter entleert werden. So werden z.B. mit einer einzigen Vorrichtung Behälter von 50 l Inhalt bis 1100 l Inhalt entleert. Für die unterschiedlich großen Behälter ist natürlich auch der jeweilige Arbeitsbereich für den Einschüttvorgang unterschiedlich groß. Deshalb kann die Abschirmung für das Entleeren von z.B. kleinen Behältern auch entsprechend dem Platzbedarf angepaßt werden. Aus diesem Grund ist die Abschirmung über Führungsschienen beweglich mit dem Sammelbehälter verbunden, um sie nur so weit wie erforderlich in eine Gebrauchslage zu bringen. Selbstverständlich ist es dadurch auch möglich, die Abschirmung in eine völlig passive Stellung zu bringen, wie es z.B. für die jeweilige Fahrstrecke des Müllfahrzeuges zur Deponie oder auch zwischen den einzelnen Behälteraufnahmen wünschenswert ist.In a further embodiment of the invention it is provided that the wall parts forming the shield are movably connected to the collecting container via guide rails. This measure is advantageous because containers of different sizes are emptied with the pouring devices. For example, containers with a capacity of 50 l to 1100 l are emptied with a single device. For the different sized containers, the respective work area for the pouring process is of course also different in size. Therefore, the shielding for emptying small containers, for example, can also be adapted according to the space required. For this reason, the shield can be moved with the collecting container via guide rails connected to bring them into a position of use only as far as necessary. Of course, this also makes it possible to bring the shielding into a completely passive position, as is desirable, for example, for the respective route of the refuse vehicle to the landfill or between the individual container receptacles.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Abschirmung mindestens einen elektrischen Steuerstromkreis für die Hubkipp- oder Kippvorrichtung aufweist und mindestens einem der Wandelemente ein elektrischer Schalter zugeordnet ist, der in dem elektrischen Steuerstromkreis angeordnet ist und der nur in der geschlossenen Arbeitsstellung der Abschirmung eingeschaltet ist.In a further embodiment of the invention it is provided that the shield has at least one electrical control circuit for the lift and tilt device and at least one of the wall elements is assigned an electrical switch which is arranged in the electrical control circuit and which is only switched on in the closed working position of the shield is.

Damit wird erreicht, daß die Abschirmung wie ein Sicherheitsgitter wirkt und der Einschüttvorgang erst bei geschlossener Abschirmung ausgelöst werden kann. Je nach Schaltung des Steuerstromkreises ist es auch möglich, die Einschüttbewgung der Hubkipp-  oder Kippvorrichtung durch das Schließen der Abschirmung selbst einzuleiten.This ensures that the shield acts like a safety grille and the pouring-in process can only be triggered when the shield is closed. Depending on the circuit of the control circuit, it is also possible to initiate the pouring movement of the lifting and tipping device by closing the shield itself.

Bei einer sinnvollen Weiterbildung der Erfindung ist vorgesehen, daß die Wandteile der Abschirmung aus teleskopartig verschiebbaren Elementen bestehen. Durch diese Maßnahme ist es möglich, die Abschirmung jeweils nur auf die erforderliche Gebrauchsstellung in Abhängigkeit von der verwendeten Einschüttvorrichtung bzw. Behältergröße zu bringen oder sie in der passiven Stellung mit geringstem Platzbedarf am Sammelbehälter unterzubringen.In a useful development of the invention it is provided that the wall parts of the shield consist of telescopically displaceable elements. This measure makes it possible to bring the shielding to the required position of use depending on the pouring device or container size used, or to accommodate it in the passive position with the smallest space requirement on the collecting container.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Abschirmung an einem Zwischenrahmen in der Nähe der Einschüttöffnung des Sammelbehälters angebracht ist. Das hat den Vorteil, daß die Abschirmung als Bausatz über den Zwischenrahmen auch an vorhandenen Fahrzeugen bzw. Sammelbehältern nachträglich angebracht werden kann.
Eine weiterer Vorteil dieser Ausgestaltung besteht darin, daß für die unterschiedlichen Fahrzeug- bzw. Sammelbehältertypen jeweils ein Zwischenrahmen mit den entsprechenden Anschlußmaßen für Sammelbehälter und Abschirmung vorbereitet werden kann, das erspart aufwendige Anpassungsarbeiten bei der Montage der Abschirmung.In a further embodiment of the invention it is provided that the shield is attached to an intermediate frame in the vicinity of the pouring opening of the collecting container. This has the advantage that the shielding can also be retrofitted to existing vehicles or collecting containers as a kit via the intermediate frame.
Another advantage of this embodiment is that an intermediate frame with the corresponding connection dimensions for the collecting container and shielding can be prepared for the different types of vehicle or collecting container, which saves time-consuming adaptation work when installing the shielding.

In einer weitern Fortbildung der Erfindung ist vorgesehen, daß zum Einstellen der Abschirmung in die Gebrauchs- und Ruhestellung Druckmittelmotore oder Elektromotore mit Seilaufwicklung vorgesehen sind. Der Vorteil dieser Maßnahme ist darin zu sehen, daß die Abschirmung quasi mittels Knopfdruck ein-und ausfahrbar ist.In a further development of the invention it is provided that pressure medium motors or electric motors with rope winding are provided for setting the shield in the use and rest position. The advantage of this measure can be seen in the fact that the shield can be extended and retracted virtually at the push of a button.

Die weiteren sinnvollen Ergänzungen der Erfindung ergeben sich aus den verbleibenden Unteransprüchen.The further useful additions to the invention result from the remaining subclaims.

Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichdnung näher erläutert. Es zeigt:

Bei den in der Zeichnung dargestellten Ausführungsbeispielen der Fig. 1 bis 3 handelt es sich um eine Schutzvorrichtung für den Arbeitsbereich einer Hubkipp- oder Kippvorrichtung 1, die an einem Sammelbehälter 2 im gezeigten Beispiel am Sammelbehälter 2 eines Müllfahrzeuges 3 - angeordnet ist. Die Figur 1 der Zeichnung zeigt eine Hubkippvorrichtung 1 mit Schwenkarmen 4, an welchen üner eine Gelenkführung 5 ein Hubwagen 6 angeordnet ist. Der Hubwagen 6 besteht aus einer oberen Greifschiene 7 und einer unteren Abstützung 8 und wird mittels Druckmittelzylindern 9 angehoben bzw. abgesenkt. Die Greifschiene 7 erstreckt sich nahezu über die gesamte Breite der Einschüttöffnung 10 des Sammelbehälters 2 und kann verschieden große Behälter aufnehmen und nach dem Anheben mit Hilfe von hydraulisch angetriebenen Schwenkmotoren 11 in die Einschüttöffnung 10 einkippen und entleeren.1 to 3 is a protective device for the working area of a lifting and tipping device 1, which is arranged on a collecting container 2 in the example shown on the collecting container 2 of a garbage truck 3. FIG. 1 of the drawing shows a lifting and tipping device 1 with swivel arms 4, on which a lifting carriage 6 is arranged via an articulated guide 5. The lifting truck 6 consists of an upper gripping rail 7 and a lower support 8 and is raised or lowered by means of pressure medium cylinders 9. The gripping rail 7 extends almost over the entire width of the pouring opening 10 of the collecting container 2 and can accommodate containers of different sizes and, after being raised, can be tipped into the pouring opening 10 with the aid of hydraulically driven swivel motors 11 and emptied.

Es ist auch bekannt, statt der gezeigten Vorrichtung zwei kleine Hubkippvorrichtungen vorzusehen, die unabhängig voneinander betätigt werden können.
Es können weiter auch solche Hubkipp- oder Kippvorrichtungen benutzt werden, die keinen Schwenkarm besitzen sondern lediglich einen senkrecht geführten Hubwagen, der am Ende des Hubweges über Gelenk- oder Kurvenführung in eine Schwenkbewegung übergeht und dadurch dei Behälter in die Einschüttöffnung 10 entleert.
Die Art der Hubkippvorrichtung ist für die Erfindung dann auch nur insofern von Bedeutung, als durch sie der benötigte Arbeitsraum hinter bzw. seitlich der Einschüttöffnung 10 wesentlich bestimmt wird.It is also known to provide two small lifting and tilting devices, which can be actuated independently of one another, instead of the device shown.
It is also possible to use lifting and tipping devices which do not have a swivel arm but only a vertically guided lifting truck which, at the end of the lifting path, changes into a swiveling movement via articulated or curved guides and thereby empties the container into the pouring opening 10.
The type of lifting and tipping device is then only of importance for the invention insofar as it essentially determines the required working space behind or to the side of the pouring opening 10.

Die Figur 1 zeigt weiter die erfindungsgemäße Schutzvorrichtung, die im gezeigten Beispiel als Abschirmung 12 für den Arbeitsbereich der Hubkippvorrichtung 1 vorgesehen ist. Die Abschirmung 12 besteht aus mehreren Wandteilen 13, 14, 15, 16 und wird in ihrer hier gezeigten passiven Stellung in Führungsschienen 17 am Sammelbehälter 2 gelagert.FIG. 1 further shows the protective device according to the invention, which in the example shown is provided as a shield 12 for the working area of the lift-tilt device 1. The shield 12 consists of several wall parts 13, 14, 15, 16 and is mounted in the passive position shown here in guide rails 17 on the collecting container 2.

Wie die Fig. 2 zeigt, sind dei Wandteile 13, 14, 15 der Abschirmung 12 in Einzelelemente a b c aufgeteilt und teleskopartig in die Gebrauchsstellung zu verschieben. Dazu werden hier nicht näher dargestellte Hydraulikmotoren mit Kolben-Zylinder-Einheit und scherenartig wirkendem Zug-Schubgestänge benutzt oder Elektromotoren mit Seilaufwicklern. Jede andere sich anbietende sinnvolle Antriebsart ist möglich.As shown in FIG. 2, the wall parts 13, 14, 15 of the shield 12 are divided into individual elements a b c and are telescopically displaceable into the use position. For this purpose, hydraulic motors (not shown in more detail) with a piston-cylinder unit and scissor-type pull-push linkage are used, or electric motors with rope winders. Any other reasonable type of drive is possible.

Obgleich alle Wandteile einzeln für sich verschiebbar angeordnet sein können, ist es vorteilhaft, die Wandteile 13, 14, 15 gemeinsam in die Gebrauchs- oder Ruhestellung zu bringen, während nur der abschließende, im gezeigten Beispiel der rückwärtige Wandteil 16 einzeln verschiebbar bzw. beweglich angeordnet ist.Although all the wall parts can be arranged individually displaceably, it is advantageous to bring the wall parts 13, 14, 15 together into the use or rest position, while only the final, in the example shown, the rear wall part 16 is arranged individually displaceably or movably is.

Unter abschließendem Wandteil der Abschirmung 12 ist der Wandteil zu verstehen, der für das Bedienungspersonal zum Heranbringen der Bahälter an die Hubkippvorrichtung offengehalten wird. Das ist im Regelfall zwar der rückwärtige Wandteil. Jedoch kommt es hierbei ausschließlich auf die Arbeitsweise des Bedienungspersonals bzw. der Hubkippvorrichtung an.
So ist es selbstverständlich, daß bei Hubkippvorrichtungen, die die Behälter seitlich, z.B. vom Straßenrand, selbsttätig aufnehmen oder solche, bei denen das Bedienungspersonal die Behälter an eine Vorrichtung heranbringt, die nicht in der überwiegend gebräuchlichen Richtung einkippt, der Wandteil als abschließender Wandteil vorgesehen ist, der unter Berücksichtigung aller äußeren Einflüsse am besten geeignet erscheint.The final wall part of the shield 12 is to be understood as the wall part which is kept open for the operating personnel to bring the container to the lifting and tipping device. As a rule, this is the rear part of the wall. However, it is only the operation of the operating personnel or the lifting and tipping device that matters.
So it goes without saying that in the case of lifting and tipping devices which automatically pick up the containers from the side, e.g. from the roadside, or those in which the operating personnel brings the containers to a device which does not tip in the predominantly common direction, the wall part is provided as the final wall part that appears to be the most suitable considering all external influences.

Im gezeigten Beispiel der Figur 2 ist der rückwärtige Wandteil 16 so weit geöffnet, daß das Bedienungspersonal ungehindert die Müllbehälter an die Hubkippvorrichtung 1 heranbringen kann. Die Öffnungsweite wird durch hier nicht dargestellte Sensoren, Lichtschranken oder auch manuelle Voreinstellung geregelt. Das gilt auch für das Schließen des Wandteiles 16.In the example shown in FIG. 2, the rear wall part 16 is opened to such an extent that the operating personnel can bring the refuse containers to the lifting and tipping device 1 unhindered. The opening width is regulated by sensors, light barriers or manual presetting, not shown here. This also applies to the closing of the wall part 16.

Der rückwärtige Wandteil 16 überfährt beim Schließvorgang einen Schalter 18,l der einen Steuerstromkreis schließt. Die Bedienung der Hubkippvorrichtung ist erst möglich, wenn dieser Steuerstromkreis geschlossen ist.The rear wall part 16 runs over a switch 18 during the closing process, which closes a control circuit. The lifting and tipping device can only be operated when this control circuit is closed.

Diese Steuerung kann aber auch so angelegt sein, daß mit dem Überfahren des Schalters 18 mit einer gewissen zeitlichen Verzögerung die Hubkippvorrichtung 1 selbsttätig ihre Arbeitsbewegung ausführt.However, this control can also be designed so that when the switch 18 is passed over with a certain time delay, the lifting and tilting device 1 automatically carries out its working movement.

Bei dem in Fig. 3 gezeigten Beispiel ist die Abschirmung 12 an einem Zwischenrahmen 19 angeordnet, der oberhalb der Einschüttöffnung 10 des Sammelbehälters 2 angeordnet ist. Der Zwischenrahmen 19 ist in den Führungsschienen 17 verschiebbar gelagert und kann so in eine Gebrauchs- oder Ruhestellung gebracht werden. Die Wandteile 13, 14, 16 bestehen bei diesem Beispiel aus lamellenartig gefaltetem Material, die von oben über Seilzüge 20 herabgelassen werden. Es können aber auch teleskopartig verschiebbare oder jalousienartige Wandteile vorgesehen sein. Der Wandteil 15 kann aus einem Spanntuch bestehen, das mit dem Zwischenrahmen 19 mittels Federaufwicklern aus-bzw. einziehbar ist, wenn die Abschirmung 12 manuell betätigt wird. Der Zwischenrahmen 19 bzw. die Abschirmung 12 kann aber auch wie in dem zuvor beschriebenen Beispiel nach Fig. 1 und 2 mittels geeigneter Kraftmittel automatisch in Gebrauchs- und Ruhestellung gefahren werden.In the example shown in FIG. 3, the shield 12 is arranged on an intermediate frame 19, which is arranged above the pouring opening 10 of the collecting container 2. The intermediate frame 19 is slidably mounted in the guide rails 17 and can thus be brought into a use or rest position. In this example, the wall parts 13, 14, 16 consist of material folded in the manner of a lamella, which are lowered from above by means of cables 20. But it can also be provided telescopically displaceable or blind-like wall parts. The wall part 15 can consist of a tensioning cloth, which can be moved out or in with the intermediate frame 19 by means of spring winders. is retractable when the shield 12 is operated manually. The intermediate frame 19 or the shield 12 can, however, as in the previously described example according to FIGS. 1 and 2, be automatically moved into the use and rest position by means of suitable power means.

Der Zwischenrahmen 19 kann auch für eine Abschirmung, wie nach Fig. 1 und 2 gezeigt, verwendet werden. In diesem Fall werden die Führungsschienen 17 vorzugsweise in Verbindung mit dem Zwischenrahmen angebracht.
Die Wandteile 13, 14, 15, 16 der Abschirmung 12 sind vorzugsweise aus schalldämpfendem Material hergestellt, welches in einer Sicherheits/Warnfarbe eingefärbt ist. Dadurch werden einerseits die Geräusche der Hubkipp- oder Kippvorrichtung 1 bzw. die Einkippgeräusche auf ein Minimum reduziert, andererseits bedeutet die Warnfarbe einen Sicherheitsfaktor für unbeteiligte Dritte.The intermediate frame 19 can also be used for a shield, as shown in FIGS. 1 and 2. In this case, the guide rails 17 are preferably attached in connection with the intermediate frame.
The wall parts 13, 14, 15, 16 of the shield 12 are preferably made of sound-absorbing material which is colored in a safety / warning color. On the one hand, this reduces the noise of the lifting and tipping device 1 or the tipping noise to a minimum, on the other hand, the warning color means a safety factor for uninvolved third parties.

Die Erfindung beschränkt sich nicht auf das gezeigte Beispiel, sie kann auch bei anderen hier nicht beschriebenen Sammelbehältern bzw. Einschüttvorrichtungen zur Anwendung kommen, so z.B. bei sogenannten Frontladesystemen, bei welchen die Müllbehälter in ein Müllsammelfahrzeug von der Vorderseite her entleert werden. Hierbei ist lediglich zu beachten, daß die Abschirmung 12 ohne den oberen Wandteil 15 angebracht wird, wenn der Müllbehälter in eine Einschüttöffnung entleert wird, die oberhalb und hinter dem Fahrerhaus des Müllsammelfahrzeugs angeordnet ist. Ihre Anwendung ist denkbar auch bei Anordnung von zwei unabhängig nebeneinander arbeitenden Einzelschüttungen, bei welchen der abschließende Wandteil 16 dann, wie z.B. in Fig. 2 in unterbrochenen Linien angedeutet, den Arbeitsbereich der jeweiligen Einzelschüttung separat abschließen kann.The invention is not limited to the example shown, it can also be used in other collecting containers or pouring devices not described here, e.g. in so-called front loading systems, in which the refuse containers are emptied from the front into a refuse collection vehicle. It should only be noted here that the shield 12 is attached without the upper wall part 15 when the waste container is emptied into a pouring opening which is arranged above and behind the driver's cab of the refuse collection vehicle. Their use is also conceivable with the arrangement of two individual beds working independently next to one another, in which case the final wall part 16, e.g. indicated in broken lines in FIG. 2, can separate the working area of the respective individual bed separately.
