Description

Die Erfindung bezieht sich auf einen insbesondere auf Fahrzeugen, Anhängern od. dgl. anbringbaren Sammelgut-Behälter, gemäß erstem Teil des Patentanspruchs 1.The invention relates to a groupage container which can be attached in particular to vehicles, trailers or the like, according to the first part of patent claim 1.

Bei der Straßenreinigung und insbesondere bei der Landschaftspflege kommt es darauf an, Abfälle wie Flaschen, Plastikflaschen, Pappbecher, Dosen usw. möglichst rationell für den Transport zur Müllbeseitigung einzusammeln. Dabei besteht die Schwierigkeit, daß diese Abfallstücke oft weit voneinander verstreut sind, was bei deren Auflesen zu einem besonders großen Zeitaufwand führt. In Parkanlagen, Freibädern u. dgl. sind zwar zahlreiche Abfallkörbe aufgestellt, welche zum Entleeren in Müll-Fahrzeuge leicht entnehmbar sind. Dies erfordert jedoch zusätzlichen konstruktiven Aufwand für die Müll-Körbe. Zudem ist ihr Aufnahmevermögen - wegen des heutzutage in großen Mengen anfallenden Abfalls - schnell erschöpft, so daß in deren Reichweite nach kurzer Zeit der Boden mit verstreut liegenden Abfallteilen übersät ist.When cleaning the streets and especially landscaping, it is important to collect waste such as bottles, plastic bottles, paper cups, cans, etc. as efficiently as possible for transport to remove waste. The difficulty is that these pieces of waste are often widely scattered, which leads to a particularly large expenditure of time when they are picked up. In parks, outdoor pools and the like. Like. Numerous waste baskets are set up, which are easily removable for emptying in refuse vehicles. However, this requires additional design effort for the trash baskets. In addition, their absorption capacity - because of the waste accumulating in large quantities nowadays - is quickly exhausted, so that within a short time the ground is littered with scattered waste parts.

Bei einem bekannten Sammelgut-Behälter etwa der eingangs genannten Art (US-A-3 348 258) ist ein maschinell angetriebener Ausleger mit einer Düse verbunden. Über eine Fernsteuerung kann der Ausleger nicht jedoch die Düse positioniert werden, so daß die Düse Abfall vor einem zugehörigen Trägerfahrzeug oder an dessen Seite auflesen kann. Andererseits kann der Ausleger mit der Düse wieder in eine Stellung zurückbewegt werden, in der dem Fahrer eine ungehinderte Sicht auf die Straße gegeben ist. Zudem kann die Ausleger-Düsenanordnung auch in eine Stellung seitlich des Trägerfahrzeugs bewegt werden, so daß ein Passieren von Unterführungen, unterhalb von Bäumen usw. möglich ist.In a known groupage container of the type mentioned at the beginning (US-A-3 348 258), a mechanically driven boom is connected to a nozzle. However, the boom cannot be positioned via a remote control, so that the nozzle can pick up waste in front of an associated carrier vehicle or on its side. On the other hand, the boom with the nozzle can be moved back into a position in which the driver is given an unobstructed view of the road. In addition, the boom nozzle arrangement can also be moved into a position to the side of the carrier vehicle, so that it is possible to pass underpasses, below trees, etc.

Eine bekannte Mähvorrichtung (vgl. das unter Nr. 0 016 440 veröffentlichte, Europäische Patent) weist einen Behälter der eingangs genannten Art auf, in dem ein Gebläse und dessen Antriebsvorrichtung untergebracht sind. Dieses wirkt auf einen die Behälterwand durchbrechenden Einlaßstutzen, an den über einen teleskopartig federnden Schnellverschluß eine flexible Rohrleitung angeschlossen ist. Die Rohrleitung führt zu einem Ansaugkasten, der Sammelgut aufnimmt und über das Gebläse in den Behälter einbläst. Sollen mit einer derartigen Vorrichtung voneinander weit verstreut liegende Abfälle in den Behälter eingesammelt oder auch Abfallkörbe entleert werden, ist neben einer Person zur Bedienung des Fahrzeuges zumindest noch eine weitere Person notwendig, welche die flexible Rohrleitung mit Ansaugkasten in entsprechende Stellungen zum Auflesen der Abfallstücke bringt.A known mowing device (cf. the European patent published under No. 0 016 440) has a container of the type mentioned in the introduction in which a fan and its drive device are accommodated. This acts on an inlet port breaking through the container wall, to which a flexible pipeline is connected via a telescopically resilient quick-release fastener. The pipeline leads to a suction box, which collects groupage and blows into the container via the blower. If waste such as this is to be used to collect waste that is widely scattered from one another in the container or to empty waste baskets, in addition to one person to operate the vehicle, at least one other person is required who brings the flexible pipeline with suction box into appropriate positions for picking up the waste pieces.

Ein bekannter Ausleger für den Saugschlauch von Straßenkehrmaschinen (DE-A-20 52 160) ist um eine stehende Achse schwenkbar sowie heb- und senkbar ausgeführt. Er ist aus einem den Saugschlauch tragenden Untergurt und einem Obergurt zusammengesetzt, welche aus mindestens drei untereinander angelenkten Winkelhebeln bzw. einer Gelenkkette ausgeführt sind. Um auch Saugschläuche großen Durchmessers, etwa in der Größenordnung von 300 mm lichter Weite pfleglich bedienen zu können, sollen diese bei Einschwenken des Auslegers um den stehenden Achszapfen bei engster Krümmung vor die rückwärtige Stirnwand innerhalb des Fahrzeugsprofils während der Transportfahrt gehalten werden.A known boom for the suction hose of street sweepers (DE-A-20 52 160) can be pivoted about a standing axis and can be raised and lowered. It is composed of a lower flange carrying the suction hose and an upper flange, which are made up of at least three angle levers articulated to one another or an articulated chain. In order to be able to use suction hoses with a large diameter, for example of the order of magnitude of 300 mm, they should be kept within the vehicle profile during the transport journey when the boom is swung in around the standing axle journal with the tightest curvature in front of the rear bulkhead.

Ferner ist ein Sauggerät zum Absaugen von organischen Abfällen bekannt (DE-A 30 42 510), dessen Saugkopf kippbar um eine in Fahrtrichtung liegende horizontale Achse an einem Ausleger sitzt, wobei ein mit dem Ausleger beweglicher Saugrüssel vorgesehen ist. Im Inneren des Sauggehäuses ist eine Arbeitswelle mit bodenparalleler Achslage vorgesehen, welche mit radial über die seitlichen Sauggehäusewände bis etwa zum Bodenkontakt vorstehenden, nachgiebigen Stäben zum Lockern des abzusaugenden Materials ausgerüstet ist. Die so untergebrachte Arbeitswelle führt allerdings zu einem erheblichen Durchmesser der Saugeinzugsöffnung.Furthermore, a suction device for suctioning organic waste is known (DE-A 30 42 510), the suction head of which can be tilted around a horizontal axis lying in the direction of travel Boom sits, with a proboscis movable with the boom being provided. In the interior of the suction housing there is a working shaft with an axis position parallel to the floor, which is equipped with flexible rods protruding radially beyond the side suction housing walls up to approximately contact with the floor to loosen the material to be extracted. However, the working shaft accommodated in this way leads to a considerable diameter of the suction intake opening.

Bei einem fahrbaren Saugreinigungsgerät (DE-U 87 07 111) ist ein ferngesteuert verschwenkbarer Saugrüssel vorgesehen, der an seinem Ende ein Anschlußteil für den Anbau eines Saugmähkopfes aufweist. Um diesen Saugrüssel unter Ausnutzung der vorhandenen Kontruktionsteile mit geringem baulichen Aufwand und Zeitaufwand auch zu einem Reinigungsgerät zur Beseitigung von Flaschen, Büchsen und dergleichen umrüsten zu können, wird vorgeschlagen, anstelle des Saugmähkopfes einen Anschlußdeckel in der Mündung des Saugrüssels anzubringen. Dieser Abschlußdeckel besitzt eine verkleinerte Öffnung für den Anschluß eines zusätzlichen flexiblen Saugschlauches. Damit auch sperriges Sammelgut wie Flaschen, Büchsen usw. durch den Saugschlauch zum nachgeordneten Saugrüssel gelangen kann, wird vorgeschlagen, den Durchmesser des Saugschlauches mit einem entsprechend ausreichenden Querschnitt zu versehen. Desweiteren weisen die flexiblen Saugschläuche an ihren als Saugmündung dienenden freien Enden Handgriffe zum Erfassen durch eine Bedienungsperson auf. Eine direkte Positionierung der Saugmündung der Saugschläuche durch den an sich vorhandenen Stellzylinder findet nicht statt; stattdessen sind die Saugschläuche über Halterungsstangen mit Drehlagern von einer Stütze getragen, welche an dem Abschlußdeckel des nachgeordneten Saugrüssels sitzt. Die Anordnung ist derart getroffen, daß die Saugmündung des Saugschlauches dicht oberhalb des zu reinigenden Straßennebenraumes hängt und von der Bedienungsperson mit leichtem Kraftaufwand in die Saugstellung abgesenkt werden kann.In a mobile suction cleaning device (DE-U 87 07 111), a remotely pivotable suction nozzle is provided, which has a connecting part at its end for the attachment of a suction mower head. In order to convert this proboscis to a cleaning device for removing bottles, cans and the like, using the existing construction parts with little construction effort and time, it is proposed to install a connection cover in the mouth of the proboscis instead of the suction mowing head. This cover has a smaller opening for connecting an additional flexible suction hose. So that bulky groupage such as bottles, cans, etc. can reach the downstream suction nozzle through the suction hose, it is proposed to provide the diameter of the suction hose with a correspondingly sufficient cross section. Furthermore, the flexible suction hoses have handles on their free ends serving as suction mouths for grasping by an operator. There is no direct positioning of the suction mouth of the suction hoses by the actuating cylinder which is present per se; instead, the suction hoses are supported on support rods with swivel bearings by a support which sits on the end cover of the downstream suction nozzle. The arrangement is such that the suction mouth of the suction hose is just above of the street side space to be cleaned depends and can be lowered into the suction position by the operator with slight effort.

Mithin ergibt sich die der Erfindung zugrundeliegende Aufgabe, gattungsgemäße Sammelgut-Behälter so zu verbessern, daß einer einzigen Bedienperson ein effizientes und präzis durchführbares Einsammeln weit verstreuten Abfalles beliebiger Abmessungen ermöglicht wird; insbesondere soll ein Verstopfen und Blockieren der Rohrleitung durch sperrige Abfälle einerseits und ein großer Rohrdurchmesser für den Saugarm und die damit verbundenen Druckverluste andererseits vermieden werden. Zur Lösung der genannten Nachteile und Probleme des Standes der Technik wird ein im Patentanspruch 1 gekennzeichneter Sammelgut-Behälter vorgeschlagen. Damit können die Rohrleitungs-Durchmesser ausreichend kleingehalten werden; größere Rohrdurchmesser würden wegen der dabei resultierenden Druckverluste zu einem unverhältnismäßig hohen Aufwand bei der Auslegung und Stärke des Sauggebläses führen. Ferner ermöglicht die Erfindung im Saugbetrieb, daß vor allem die Einzugsöffnung der Rohrleitung präzise auf das einzusammelnde Objekt ausgerichtet werden kann, damit dieses von der Saugströmung sicher erfaßt und wegbefördert wird. Mit der erfindungsgemäß ausgestalteten Saugarm-Einzugsöffnung wird eine Einsaugdüse geschaffen, mittels welcher auch sehr kleines Sammelgut sicher erfaßt werden kann.The object underlying the invention is therefore to improve generic groupage containers in such a way that a single operator is able to collect widely scattered waste of any dimensions efficiently and precisely; in particular, clogging and blocking of the pipeline due to bulky waste on the one hand and a large pipe diameter for the suction arm and the associated pressure losses on the other hand should be avoided. To solve the mentioned disadvantages and problems of the prior art, a groupage container characterized in claim 1 is proposed. This allows the pipe diameter to be kept sufficiently small; Larger pipe diameters would lead to a disproportionate effort in the design and strength of the suction fan due to the resulting pressure losses. Furthermore, the invention in suction mode enables that, above all, the feed opening of the pipeline can be precisely aligned with the object to be collected, so that it is reliably grasped by the suction flow and transported away. With the suction arm feed opening designed according to the invention, a suction nozzle is created, by means of which even very small groupage can be reliably detected.

Die Erfindung macht sich vorteilhaft den Sachverhalt zunutze, daß heute gebräuchliche Müll-Container, Sammelgut-Behälter u. dgl. leicht auf ein Kraftfahrzeug oder einen Anhänger aufbringbar ausgeführt sind, so daß im Sinne der Erfindung der Fahrer durch Betätigung eines oder mehrerer Stellantriebe, vorzugsweise vom Fahrersitz aus, die zumindest teilweise flexible Rohrleitung zu den einzelnen, voneinander verstreut liegenden Abfallteilen positionieren kann. Die Positionierung mittels Betätigung der Stellantriebe kann dabei durch gezieltes Vorwärts-, Rückwärts-, Links- und Rechts-Fahren mit dem Fahrzeug ergänzt werden. Mit der erfindungsgemäßen Maßnahme, die flexible Rohrleitung einerseits zu versteifen und andererseits deren Gelenkigkeit weitgehend beizubehalten, wird diese zu einem gelenkigen Saugarm weitergebildet, welcher mit steigender Anzahl der Gelenkstellen und/oder der Stellantriebe um so genauer zu einem Abfallteil plaziert werden kann.The invention takes advantage of the fact that garbage containers, groupage containers u. Like. Can be easily applied to a motor vehicle or a trailer, so that in the sense of the invention the driver by actuating one or more actuators, preferably from the driver's seat, the at least partially flexible pipe to the individual, scattered waste parts can position. Positioning by actuating the actuators can be supplemented by driving the vehicle forward, backward, left and right. With the measure according to the invention, on the one hand stiffening the flexible pipeline and on the other hand largely maintaining its articulation, it is developed into an articulated suction arm, which can be placed more precisely to a waste part with increasing number of articulation points and / or the actuators.

Eine spezielle Realisierung dieser erfinderischen Idee besteht darin, ein die Rohrleitung halterndes Schwenkgestänge mit einem oder mehreren angelenkten Hebelabschnitten vorzusehen, welche jeweils durch wenigstens einen gegen den Behälter, das Fahrzeug und/oder einen benachbarten Hebelabschnitt abgestützten Stellantrieb verschwenkbar sind. Das derart aus einer Mehrzahl einzelner, gelenkig befestigter Hebelarme gebildete Schwenkgestänge ist mit hoher Flexibilität positionierbar. Eine besonders einfache und zur Realisierung eines von der Behälter-Seitenwand weit auskragbaren Saugarms geeignete Konstruktion des Schwenkgestänges besteht darin, daß dieses aus einer Mehrzahl kettengliedartig hintereinander angeordneter, stangenförmiger Hebelabschnitte gebildet ist, von denen der erste am Behälter, und die nachfolgenden jeweils am vom Behälter abgewandten Ende des vorhergehenden Hebelabschnitts angelenkt sind.A special realization of this inventive idea consists in providing a pivot linkage holding the pipeline with one or more articulated lever sections, each of which can be pivoted by at least one actuator supported against the container, the vehicle and / or an adjacent lever section. The pivot linkage formed in this way from a plurality of individual, articulated lever arms can be positioned with great flexibility. A particularly simple construction of the swivel linkage, which is suitable for realizing a suction arm that can be widely cantilevered from the container side wall, is that it is formed from a plurality of rod-shaped lever sections arranged one behind the other in the manner of a chain link, the first of which on the container, and the subsequent ones on the container opposite end of the previous lever section are articulated.

Um eine mechanische Stabilität gegen schwergewichtiges und/oder scharfkantiges Abfallgut zu erreichen, weist im Rahmen der Erfindung die Rohrleitung den Hebelabschnitten entsprechende, versteifte Abschnitte auf; dabei reicht es aus, wenn wenigstens im Bereich der Gelenkstellen des Schwenkgestänges die Rohrleitung flexibel biegsam ausgebildet ist. Durch das Vorsehen von versteiften Rohrabschnitten läßt sich vorteilhaft die Anzahl der Halterungselemente reduzieren, welche für die Befestigung der Rohrleitung am Schwenkgestänge notwendig sind. Der Schaffung des obengenannten, weit auskragenden Saugarms ist eine weitere Ausbildung der Erfindung angepaßt, wonach längs des Rohrleitungsverlaufs flexible und steife Rohrabschnitte hintereinander angeordnet abwechseln. Mit dieser speziellen Erfindungsausbildung wird für den Sammelgut-Behälter ein Saugorgan geschaffen, welches mechanische Stabilität und Festigkeit einerseits und hohe Flexibilität und Beweglichkeit andererseits in sich vereint und mithin zur exakten Positionierung besonders geeignet ist. Dieses Saugorgan basiert im wesentlichen auf dem länglichen, aus sukzessive aneinander angelenkten Hebelabschnitten gebildeten Schwenkgestänge, der daran befestigten, dazu Parallel verlaufenden Rohrleitung und den Stellelementen zur Gelenkbewegung.In order to achieve mechanical stability against heavy and / or sharp-edged waste material, the pipeline has stiffened sections corresponding to the lever sections within the scope of the invention; it is sufficient if at least in the area of the joints of the Swivel linkage, the pipeline is flexible and flexible. The provision of stiffened pipe sections can advantageously reduce the number of mounting elements which are necessary for fastening the pipe to the swivel linkage. A further embodiment of the invention is adapted to the creation of the abovementioned cantilevered suction arm, according to which flexible and rigid pipe sections are arranged one behind the other along the course of the pipeline. With this special invention training, a suction element is created for the groupage container, which combines mechanical stability and strength on the one hand and high flexibility and mobility on the other and is therefore particularly suitable for exact positioning. This suction element is essentially based on the elongated swivel linkage formed from successively articulated lever sections, the pipeline attached to it, running parallel thereto, and the adjusting elements for articulated movement.

Vorteilhaft sind die gattungsgemäßen Sammelgut-Behälter so gebaut, daß sie leicht auf Fahrzeugen, Anhängern u. dgl. anbringbar sind. Desweiteren ist der erfindungsgemäße Saugarm zweckmäßigerweise an einer Seitenwand des Behälters - entsprechend der Längsseite des Fahrzeugs - befestigt. Um die Positionier-Genauigkeit zu erhöhen und den Saugarm bei Nichtgebrauch an die Behälter- bzw. Fahrzeuglängsseite anlegen zu können, ist in Weiterbildung der Erfindung vorgesehen, daß der Saugarm bzw. das Schwenkgestänge am Behälter und/oder Fahrzeug um wenigstens eine horizontale und wenigstens eine vertikale Achse schwenkbar angelenkt sind.The generic groupage containers are advantageously built so that they easily on vehicles, trailers and. Like. Are attachable. Furthermore, the suction arm according to the invention is expediently fastened to a side wall of the container - corresponding to the long side of the vehicle. In order to increase the positioning accuracy and to be able to place the suction arm on the container or vehicle longitudinal side when not in use, it is provided in a development of the invention that the suction arm or the swivel linkage on the container and / or vehicle by at least one horizontal and at least one vertical axis are pivoted.

Eine mit maßvollem Herstellungs- und Konstruktionsaufwand genügend hohe Positionier-Genauigkeit ermöglichende, spezielle Ausbildung der Erfindung besteht darin, daß das Schwenkgestänge einen ersten am Behälter bzw. Fahrzeug angelenkten Hebelarm und einen an dessen davon abgewandten Ende angelenkten, zweiten Hebelarm aufweist, an dem das versteifte Rohrleitungsende angelenkt ist, und daß jeder Schwenkachse - einschließlich der horizontalen und vertikalen Schwenkachsen bezüglich der am Fahrzeug Behälter befindlichen Gelenkstellen - ein Stellantrieb zugeordnet ist, der die gelenkig verbundenen Teile - einschließlich Fahrzeug oder Behälter/Hebelstange - relativ zueinander verschwenkt. Diese Ausbildung erhöht außerordentlich die Bedienbarkeit; insbesondere kann der Fahrzeugführer hinter dem Steuerrad den zum Transport an die Behälter-Seitenwand herangeschwenkten Saugarm durch Betätigung des Stellantriebs, welcher der Saugarm-Anlenkstelle an der Behälterwand zur Realisierung der vertikalen Schwenkachse zugeordnet ist, in die beispielsweise auskragende Betriebsstellung ausfahren.A special embodiment of the invention, which enables sufficiently high positioning accuracy with moderate manufacturing and construction expenditure, consists in the fact that the Pivotal linkage has a first lever arm articulated on the container or vehicle and a second lever arm articulated on its end facing away from it, to which the stiffened pipe end is articulated, and that each pivot axis - including the horizontal and vertical pivot axes with respect to the articulation points located on the vehicle container - an actuator is assigned, which swivels the articulated parts - including the vehicle or container / lever rod - relative to each other. This training greatly increases usability; In particular, the driver can extend the suction arm swiveled towards the container side wall behind the steering wheel by actuating the actuator, which is assigned to the suction arm articulation point on the container wall for realizing the vertical pivot axis, into the cantilevered operating position, for example.

Im Rahmen der Erfindung bestehen viele technologische Möglichkeiten zur Realisierung der Stellantriebe (z. B. elektrisch, hydraulisch oder pneumatisch). Besonders vorteilhaft ist die Ausbildung der Stellantriebe als pneumatische Stellzylinder, deren Enden jeweils an einem von zwei benachbarten, gelenkig miteinander verbundenen Saugarmabschnitten angreifen. Der Vorteil der pneumatischen Realisierung besteht darin, daß Druckluft als Steuerungs- und Ahtriebsmedium verwendet werden kann, welche verhältnismäßig geringes Gewicht aufweist. Mithin ergeben Pneumatische Linearantriebe eine leichte Bauweise; zudem zeichnen sich die pneumatischen Stellzylinder durch ein schnelles Ansprechverhalten und eine ausreichende Positioniergenauigkeit aus.Within the scope of the invention, there are many technological possibilities for realizing the actuators (e.g., electrically, hydraulically or pneumatically). It is particularly advantageous to design the actuators as pneumatic actuating cylinders, the ends of which each engage one of two adjacent suction arm sections which are connected to one another in an articulated manner. The advantage of the pneumatic implementation is that compressed air can be used as the control and drive medium, which has a relatively low weight. Pneumatic linear drives therefore result in a lightweight construction; In addition, the pneumatic actuating cylinders are characterized by their quick response and sufficient positioning accuracy.

Zur Entlastung bzw. zum Kraftausgleich für die Stellzylinder sind in Weiterbildung dieser speziellen Ausbildung wenigstens den besonders belasteten Stellzylindern je ein oder mehrere Federelemente zugeordnet, deren Angriffspunkte denen des Stellzylinders entsprechen. M. a. W., die Federelemente sind den Bewegungen der Stellantriebe wirkungsmäßig parallel geschaltet. Damit wird - insbesondere bei der auskragenden Ausführung des Saugarms - der Vorteil erzielt, daß bei dessen Senken die Federn gespannt werden und mithin die Stellzylinder vom Gesamtgewicht des Saugarms entlasten; beim Einfahren bzw. Heben des vorher ausgefahrenen Saugarms werden die entsprechenden Stellbewegungen der Zylinder durch die Rückstellkraft der vorgespannten Federelemente unterstützt und mithin die Stellzylinder entlastet. Folglich ermöglichen die Federelemente eine wesentlich kleinere Dimensionierung der Stellantriebe.In order to relieve or to balance the force for the actuating cylinders, in a further development of this special design at least one or more spring elements are assigned to each of the particularly loaded actuating cylinders, the points of engagement of which correspond to those of the actuating cylinder. M. a. W., the spring elements are connected in effect to the movements of the actuators in parallel. This has the advantage, in particular in the projecting design of the suction arm, that the springs are tensioned when the suction arm is lowered and thus relieve the actuating cylinders of the total weight of the suction arm; When retracting or lifting the previously extended suction arm, the corresponding actuating movements of the cylinders are supported by the restoring force of the prestressed spring elements, and the actuating cylinders are thus relieved. As a result, the spring elements enable the actuators to be dimensioned much smaller.

Eine andere vorteilhafte Realisierung der Stellantriebe ist durch elektronische Schrittmotoren denkbar.Another advantageous realization of the actuators is conceivable using electronic stepper motors.

Allgemein ist auf Sicherheit und Bequemlichkeit bei der Bedienung technischer Einrichtungen Wert zu legen. Um bei den vorliegenden Einsatzfällen dem Fahrzeugführer insbesondere eine Bedienung des erfindungsgemäßen Saugarms hinter dem Steuerrad sowie nach dessen beendigter Betätigung ein Öffnen der Fahrertür zu ermöglichen, ist in Weiterbildung der Erfindung eine relativ zur Behälterwand positionierbar angebrachte Bedieneinrichtung vorgesehen, mit der die einzelnen Stellantriebe betätigt werden können. Nach einer besonderen Ausbildung der Erfindung weist die Bedieneinrichtung Betätigungshebel auf, die je einem Stellantrieb zugeordnet sind und in Stellungen für das Einfahren, Ausfahren und den Stillstand der einzelnen Stellantriebe positionierbar sind.In general, safety and convenience when operating technical facilities is important. In order to enable the vehicle driver in particular to operate the suction arm according to the invention behind the steering wheel as well as to open the driver's door after it has been actuated, a further development of the invention provides an operating device which can be positioned relative to the container wall and with which the individual actuators can be actuated . According to a special embodiment of the invention, the operating device has actuating levers which are each assigned to an actuator and can be positioned in positions for retracting, extending and stopping the individual actuators.

In besonderer Ausbildung der Erfindung ist das Zerkleinerungswerkzeug am die Einzugsöffnung des Saugarms bildenden Abschnitt derart angelenkt, daß dieses Werkzeug um etwa 90° vor die Einzugsöffnung schwenkbar ist, wobei dessen Rotationsachse schräg zur Einzugsrichtung verläuft und/oder gegenuber der mittleren Längsachse des Saugarmöffnungsabschnitts radial versetzt ist. Ein bevorzugter Antrieb für das Zerkleinerungs-, insbesondere Schneidwerkzeug ist ein Elektromotor, mit welchem hohe Drehzahlen realisiert werden können, die zur mühelosen Zerkleinerung sperriger oder mechanisch fester Abfallstücke vorteilhaft sind. In besonderer Ausbildung ist zum Einschwenken des Zerkleinerungswerkzeuges in den Bereich vor der Einzugsöffnung ein eigener Stellantrieb vorgesehen, der gegebenenfalls mit der Bedieneinrichtung vom Lenkrad-Sitz des Fahrzeugs aus betätigt werden kann. Wichtig ist eine asymmetrische Anordnung des Zerkleinerungswerkzeugs mit seiner Rotationsachse bezüglich des Öffnungsdurchmessers des Saugeinzugs, damit die Gefahr eines Verwickelns von zerschnittenen Abfallstücken um das Schneid- oder Zerkleinerungswerkzeug herum weitgehend vermieden ist.In a special embodiment of the invention, the comminution tool is articulated on the section forming the feed opening of the suction arm in such a way that this tool can be pivoted about 90 ° in front of the feed opening, the axis of rotation of which runs obliquely to the feed direction and / or is radially offset from the central longitudinal axis of the suction arm opening section . A preferred drive for the comminution, in particular cutting, tool is an electric motor, with which high speeds can be achieved, which are advantageous for the effortless comminution of bulky or mechanically solid waste pieces. In a special embodiment, a separate actuator is provided for pivoting the shredding tool into the area in front of the feed opening, which actuator can optionally be actuated from the steering wheel seat of the vehicle using the operating device. It is important to have an asymmetrical arrangement of the shredding tool with its axis of rotation with respect to the opening diameter of the suction intake, so that the risk of entangled pieces of waste getting tangled around the cutting or shredding tool is largely avoided.

Der einzusammelnde Abfall fällt in erster Linie auf der Bodenoberfläche an. Zu dessen Beseitigung ist beim Betätigen des Saugarms darauf zu achten, daß dieser zum einen nicht zu weit von der Bodenoberfläche entfernt ist und zum anderen sich nicht zu nahe an der Bodenoberfläche befindet und sich dort gar "festsaugt". Dieses Problems nimmt sich eine weitere Ausbildung der Erfindung an, nach der an der Außenwand des Saugarms im Bereich von dessen Einzugsöffnung wenigstens ein Abstandsrad befestigt ist, welches mit seinem Befestigungselement über die Kante der Einzugsdüse hinausragt. Damit werden vorteilhaft der Saugarm, gegebenenfalls dessen Schwenkgestänge und insbesondere die Stellantriebe von dem auf sie lastenden (Eigen-)Gewicht weitgehend befreit. Auch die Bedienperson braucht der Einhaltung des richtigen Abstands über der - meist unebenen - Erdoberfläche keine besondere Aufmerksamkeit mehr zu widmen. Ist gemäß einer besonderen Weiterbildung der Erfindung das Abstandrad bezüglich seiner Entfernung von der Öffnungskante der Einzugsdüse verstellbar ausgeführt, kann die Bedienperson den Abstand der Einzugsöffnung des Saugarms abhängig vom Gewicht des einzusaugenden Abfallgutes steuern. Zur Realisierung dieser (Höhen-)Verstellbarkeit kann ein weiterer, ggf. pneumatischer Stellzylinder dienen.The waste to be collected is primarily on the surface of the soil. To remove it, when operating the suction arm, make sure that it is on the one hand not too far away from the floor surface and on the other hand that it is not too close to the floor surface and is even "stuck" there. This problem is addressed by a further embodiment of the invention, according to which at least one spacer wheel is attached to the outer wall of the suction arm in the region of its feed opening, said spacer wheel projecting beyond the edge of the feed nozzle with its fastening element. This makes the suction arm, possibly its swivel linkage and in particular the actuators advantageous largely relieved of the (own) weight on them. Even the operator no longer needs to pay particular attention to maintaining the correct distance above the - usually uneven - surface of the earth. If, according to a special development of the invention, the distance wheel is adjustable in terms of its distance from the opening edge of the feed nozzle, the operator can control the distance of the feed opening of the suction arm depending on the weight of the waste material to be sucked in. Another (possibly pneumatic) actuating cylinder can be used to implement this (height) adjustability.

Gemäß Seitenansicht der Fig. 1 ist ein Behälter 1 auf den hinteren Teil eines Nutzfahrzeugs 2 aufgesetzt. Aus dem Inneren des Behälters 1 führt ein Anschlußstutzen 3 heraus, an dem sich eine Rohrleitung 4 zum Einsaugen von Sammelgut anschließt. Die Rohrleitung 4 ist aus einer Mehrzahl von einzelnen Abschnitten zusammengesetzt, nämlich aus drei flexiblen Rohrabschnitten 5a, 5b, 5c und aus drei versteiften Rohrabschnitten 6a, 6b, 6c. Die flexiblen und versteiften Rohrabschnitte sind abwechselnd hintereinander angeordnet, wobei sich an den Anschlußstutzen 3 die Rohrleitung mit einem flexiblen Rohrabschnitt 5a anschließt und im Bereich seiner Einzugsöffnung mit einem versteiften Rohrabschnitt 6c mit der Einzugsöffnung 7 endet. Die Rohrleitung 4 ist an einem Schwenkgestänge 8 aufgehängt und verläuft zu diesem etwa parallel. Das Schwenkgestänge 8 weist zwei Hebelarmabschnitte 9a, 9b sowie drei Gelenkstellen 10a, 10b, 10c auf. Der erste Hebelarm 9a ist mittels des ersten Gelenks 10a an einer vertikal verlaufenden Drehstange 11 um eine erste horizontale Achse 13a (vgl. Fig. 5) nach oben bzw. unten schwenkbar angelenkt. Die Drehstange 11 ist in einem von der Behälterseitenwand senkrecht vorspringenden (in Fig. 5 deutlich sichtbaren) Halterungssteg 12 um eine vertikale Achse 14 etwa parallel zur Behälterseitenwand drehbar gelagert. Der die entsprechende Drehbewegung erzeugende Drehantrieb 15 wird unten anhand von Fig. 5 näher erläutert.According to the side view of FIG. 1, a container 1 is placed on the rear part of a commercial vehicle 2. From the interior of the container 1 leads out a connecting piece 3, to which a pipe 4 connects for sucking in groupage. The pipe 4 is composed of a plurality of individual sections, namely three flexible pipe sections 5a, 5b, 5c and three stiffened pipe sections 6a, 6b, 6c. The flexible and stiffened pipe sections are arranged alternately one behind the other, the pipe connecting to the connecting piece 3 with a flexible pipe section 5a and ending in the region of its intake opening with a stiffened pipe section 6c with the intake opening 7. The pipeline 4 is suspended from a swivel linkage 8 and runs approximately parallel to it. The pivot linkage 8 has two lever arm sections 9a, 9b and three articulation points 10a, 10b, 10c. The first lever arm 9a is articulated by means of the first joint 10a on a vertically extending rotary rod 11 so as to be pivotable upwards and downwards about a first horizontal axis 13a (cf. FIG. 5). The rotary rod 11 is mounted in a bracket web 12 projecting vertically from the side wall of the container (clearly visible in FIG. 5) so that it can rotate about a vertical axis 14 approximately parallel to the side wall of the container. The rotary drive 15 which generates the corresponding rotary movement is explained in more detail below with reference to FIG. 5.

Das von der ersten Gelenkstelle 10a abgewandte Ende des ersten Hebelarms 9a ist über das zweite Gelenk 10b, welches eine horizontale Schwenkachse 13b realisiert, mit dem Ende des zweiten Hebelarms 9b verbunden. Dessen dem zweiten Gelenk 10b abgewandtes Ende ist über das dritte Gelenk 10c an der Außenwand des dritten versteiften Rohrabschnitts 6c angelenkt. Auch das dritte Gelenk 10c realisiert eine in horizontaler Richtung verlaufende Schwenkachse 13c (vgl. Fig. 3).The end of the first lever arm 9a facing away from the first joint point 10a is connected to the end of the second lever arm 9b via the second joint 10b, which realizes a horizontal pivot axis 13b. Its end facing away from the second joint 10b is articulated on the outer wall of the third stiffened pipe section 6c via the third joint 10c. The third joint 10c also realizes one in a horizontal manner Direction pivot axis 13c (see. Fig. 3).

Gemäß Fig. 1 greifen am Schwenkgestänge 8 drei Stellorgane bzw. Stellantriebe 16a, 16b, 16c an. Sie dienen jeweils zur Betätigung eines der drei Gelenke 10a bzw. 10b bzw. 10c. Gemäß gezeichneten Ausführungsbeispiel sind sie als pneumatische Stellzylinder realisiert. Schließlich ist der Behälter 1 nahe der Anlenkstelle 10a, 11, 12 des Schwenkgestänges 8 mit einer Bedieneinrichtung 17 versehen. Sowohl der aus Rohrleitung 4, Schwenkgestänge 8 und Stellantriebe 16a, 16b, 16c gebildete Saugarm 18 als auch die Bedieneinrichtung 17 sind in Fig. 1 in der für den Transport geeigneten Stellung gezeigt, nämlich an die Seitenwand des Behälters 1 angeklappt. Daran können sie mit (nicht gezeichneten) Halterungsmitteln befestigt sein.1, three actuators or actuators 16a, 16b, 16c act on the swivel linkage 8. They each serve to actuate one of the three joints 10a or 10b or 10c. According to the exemplary embodiment shown, they are implemented as pneumatic actuating cylinders. Finally, the container 1 near the articulation point 10a, 11, 12 of the swivel linkage 8 is provided with an operating device 17. Both the suction arm 18 formed from the pipeline 4, swivel linkage 8 and actuators 16a, 16b, 16c and the operating device 17 are shown in FIG. 1 in the position suitable for transport, namely folded against the side wall of the container 1. They can be fastened to this with mounting means (not shown).

Gemäß Fig. 2 ist die Bedieneinrichtung 17, welche an der Behälterseitenwand um eine vertikale Achse 20 schwenkbar angeordnet ist, gegenüber der in Fig. 1 gezeigten Stellung um ca. 180° verschwenkt. Bei dieser Stellung kann der hinter dem Steuerrad sitzende Führer des Fahrzeugs 2 von der Fahrzeugkabine 19 aus die Bedieneinrichtung 17 zur Betätigung des Saugarms 18 handhaben. Die Bedieneinrichtung 17 weist vier Bedienhebel 21a, 21b, 21c, 21d auf, welche auf einer an der Seitenwand des Behälters 1 angelenkten Schwenkstange 23 sitzen. Die Schwenkstange 23 ist um die bereits genannte vertikale Schwenkachse 20 drehbar gelagert. Die Bedienhebel 21a, 21b, 21c, 21d sind jeweils einem der linearen Stellantriebe 16a, 16b, 16c bzw. dem Drehantrieb 15 zugeordnet und in drei Funktionsstellungen, nämlich für Halten und die beiden Bewegungsrichtungen der Antriebe, bringbar. Die mittels der Bedienhebel 21 eingestellten Befehle werden über die Steuerleitungen 22 zu den einzelnen, genannten Antrieben 15, 16 übertragen.According to FIG. 2, the operating device 17, which is arranged on the side wall of the container so as to be pivotable about a vertical axis 20, is pivoted by approximately 180 ° with respect to the position shown in FIG. 1. In this position, the driver of the vehicle 2 sitting behind the steering wheel can manipulate the operating device 17 for actuating the suction arm 18 from the vehicle cabin 19. The operating device 17 has four operating levers 21a, 21b, 21c, 21d, which are seated on a pivot rod 23 articulated on the side wall of the container 1. The pivot rod 23 is rotatably mounted about the vertical pivot axis 20 already mentioned. The operating levers 21a, 21b, 21c, 21d are each assigned to one of the linear actuators 16a, 16b, 16c or the rotary drive 15 and can be brought into three functional positions, namely for holding and the two directions of movement of the drives. The set by means of the control lever 21 Commands are transmitted via the control lines 22 to the individual drives 15, 16 mentioned.

Gemäß Fig. 3 taucht der in Saugstellung befindliche Saugarm 18 in einen Papierkorb 24, um Abfallstücke in das Innere des Behälters 1 zu befördern. Zu diesem Zweck ist mittels des Stellantriebs 16c der am zweiten Hebelarm 9b gelenkig 10c angebrachte, versteifte Rohrabschnitt 6c, an welchem die Einzugsöffnung 7 ausgebildet ist, in die geeignete Position gebracht. Der die Verschwenkung um die horizontale Achse 13c des versteiften Rohrabschnitts 6c bewirkende Stellantrieb 16c ist mit seinem einen Ende am zweiten Hebelarm 9b abgestützt und greift mit seinem anderen Ende am versteiften, die Einsaugdüse darstellenden Rohrabschnitt 6c an.According to FIG. 3, the suction arm 18 in the suction position is immersed in a waste paper basket 24 in order to convey pieces of waste into the interior of the container 1. For this purpose, by means of the actuator 16c, the stiffened pipe section 6c, which is articulated on the second lever arm 9b and on which the feed opening 7 is formed, is brought into the suitable position. The actuator 16c, which causes the pivoting about the horizontal axis 13c of the stiffened tube section 6c, is supported at one end on the second lever arm 9b and engages at its other end on the stiffened tube section 6c, which represents the suction nozzle.

Gemäß Fig. 4 ist der das zweite Gelenk 10b bewegende Stellantrieb 16b mit seinem einen Ende gegen den ersten Hebelarmabschnitt 9a abgestützt und greift mit seinem anderen Ende am zweiten Hebelarmabschnitt 9b an. Hierdurch sind die beiden Hebelarmabschnitte 9a, 9b um die durch das Gelenk 10b verlaufende Achse 13b relativ zueinander verschwenkbar.According to FIG. 4, the actuator 16b moving the second joint 10b is supported at one end against the first lever arm section 9a and engages at the second lever arm section 9b at its other end. As a result, the two lever arm sections 9a, 9b can be pivoted relative to one another about the axis 13b extending through the joint 10b.

In Fig. 5 ist die Anbringung des Saugarms 18 am Behälter 1 vergrößert dargestellt. Der gegen einen die Drehstange 11 fortsetzenden Ansatz 25 abgestützte Stellantrieb 16a betätigt das erste Gelenk 10a, in welchem der erste Hebelarm 9a um die horizontale Achse 13a schwenkbar gelagert ist. Zu diesem Zweck greift das vom Ansatz 25 abgewandte Ende des Stellantriebs (pneumatischer Zylinder) am ersten Hebelarm 9a an (vgl. auch Fig. 1). Der Verschwenkung des Saugarms 18 um die vertikale Achse 14 dient der Drehantrieb 15. Dieser ist im wesentlichen aus einem die Drehstange 11 umgebenden Zahnkranz 26 und einem damit in Eingriff stehenden, angetriebenen Ritzel 27 gebildet. Zum Antrieb des Ritzels 27 dient ein beispielsweise elektrischer Stellmotor 28. Dieser läßt sich mittels des Bedienhebels 21d der Bedieneinrichtung 17 (vgl. Fig. 2) betätigen.In Fig. 5 the attachment of the suction arm 18 to the container 1 is shown enlarged. The actuator 16a, which is supported against an extension 25 which continues the rotary rod 11, actuates the first joint 10a, in which the first lever arm 9a is pivotably mounted about the horizontal axis 13a. For this purpose, the end of the actuator (pneumatic cylinder) facing away from the attachment 25 engages the first lever arm 9a (cf. also FIG. 1). The rotary drive 15 serves to pivot the suction arm 18 about the vertical axis 14. This is essentially composed of a toothed ring 26 surrounding the rotary rod 11 and a driven one that engages with it Pinion 27 formed. An electric servomotor 28, for example, is used to drive the pinion 27. This can be actuated by means of the operating lever 21d of the operating device 17 (cf. FIG. 2).

Gemäß Fig. 1, 3, 4 und 5 sind den ersten beiden Stellantrieben 16a, 16b jeweils ein Federelement 29a bzw. 29b zugeordnet, dessen Angriffspunkte denen des zugehörigen Stellantriebs entsprechen. M. a. W., die Federelemente 29a, 29b sind räumlich-kontruktiv sowie wirkungsmäßig parallel zu den zugeordneten Stellantrieben 16a, 16b angeordnet und üben Entlastungs- und Ausgleichsfunktionen bezüglich der Stellantriebe aus. So ist das erste Federelement 29a mit seinem der ersten Gelenkstelle 10a benachbarten Ende an dem Ansatz 25 der Drehstange 11 aufgehängt, während dessen entgegengesetztes Ende am ersten Hebelarm 9a befestigt ist. Entsprechend ist das eine Ende des zweiten Federelements 29b an einem zweiten Ansatz 30 aufgehängt, welcher mit dem ersten Hebelarm 9a starr verbunden ist. Dessen entgegengesetztes Ende ist am zweiten Hebelarm 9b befestigt. Analoges gilt für die Anbringung der ersten beiden Stellantriebe 16a, 16b, wobei jeweils deren hintere Abstütz- und vordere Angriffstellen angelenkt sind.1, 3, 4 and 5, the first two actuators 16a, 16b are each assigned a spring element 29a or 29b, the points of engagement of which correspond to those of the associated actuator. M. a. W., the spring elements 29a, 29b are arranged spatially-constructively and functionally parallel to the associated actuators 16a, 16b and perform relief and compensation functions with respect to the actuators. Thus, the first spring element 29a is suspended with its end adjacent to the first articulation point 10a on the extension 25 of the rotary rod 11, while its opposite end is attached to the first lever arm 9a. Accordingly, one end of the second spring element 29b is suspended from a second extension 30 which is rigidly connected to the first lever arm 9a. Its opposite end is attached to the second lever arm 9b. The same applies to the attachment of the first two actuators 16a, 16b, their rear support and front engagement points being articulated in each case.

Gemäß Fig. 6 ist nach einer besonderen Variante der Saugarm 18 im Bereich seiner Einzugsöffnung 7 mit einem Zerkleinerungsmotor 31 versehen, der vorzugsweise in hohen Drehzahlen betrieben wird. Mit entsprechender Geschwindigkeit rotieren Zerkleinerungsmesser 32, welche dabei angesaugte Abfallstücke zertrümmern oder zerkleinern. Dieses Zerkleinerungsgerät 31, 32 ist um 90° schräg vor die Einzugsöffnung 7 verschwenkbar ausgeführt, wie in Fig. 6 gestrichelt angedeutet. Diese Verschwenkung kann beispielsweise mittels eines weiteren (nicht gezeichneten) pneumatischen Stellzylinders herbeigeführt werden. Damit angesaugtes Samnmelgut durch die Zerkleinerungsmesser 32 nicht von der Einzugsöffnung 7 weggeschleudert wird, sind in weiterer Ausgestaltung dieser Erfindungsvariante ein an den versteiften Rohrabschnitt 6c angesetzter, die Einzugsöffnung 7 verbreiternder Trichter 33 und ein Sammelgut-Niederhalter 34 vorgesehen, welcher am Gehäuse des Zerkleinerungsmotors 31 angeformt ist.6, according to a special variant, the suction arm 18 is provided in the area of its intake opening 7 with a comminution motor 31, which is preferably operated at high speeds. Comminution knives 32 rotate at the appropriate speed, and in the process crush or shred sucked-in pieces of waste. This comminution device 31, 32 is designed to be pivotable at an angle of 90 ° in front of the feed opening 7, as indicated by dashed lines in FIG. 6. This pivoting can, for example, by means of a further (not shown) pneumatic actuating cylinder be brought about. In order that the collected material is not flung away by the shredding knife 32 from the intake opening 7, a funnel 33 attached to the stiffened pipe section 6c and widening the intake opening 7 and a groupage hold-down 34 are provided in a further embodiment of this variant of the invention, which are molded onto the housing of the shredding motor 31 is.
