Description

Die Erfindung betrifft eine selbstfahrende Vorrichtung mit einem Fahrgestell und mit einem an wenigstens einem verstellbaren Ausleger befestigten, rechteckigen Sauggreifer mit mehreren voneinander unabhängig axial- und winkelbeweglichen Saugstempeln und mit an allen Seiten gegen das Hebegut schwenkbaren Richtbacken, zum Anheben und Versetzen von Hebegut, insbesondere zum Verlegen von handelsüblichen Beton-, Klinker- und Naturpflastersteinen, wobei jeder einzelne Saugstempel als Mantel einen Faltenbalg aufweist und wobei zum Unterbrechen des Saugstromes beim Absetzen des Hebegutes für alle Saugstempel ein gemeinsames Unterbrechungsventil vorgesehen ist, nach Patent 33 24 441.The invention relates to a self-propelled device with a chassis and with a rectangular suction gripper attached to at least one adjustable boom with several suction stamps that can be moved axially and angularly independently of one another and with straightening jaws that can be pivoted against the lifting material on all sides, for lifting and moving lifting material, in particular for laying commercially available concrete, clinker and natural paving stones, wherein each individual suction stamp has a bellows as a casing and wherein a common interruption valve is provided for all suction stamps to interrupt the suction flow when the lifting material is set down, according to patent 33 24 441.

Mit dem eingangs genannten Sauggreifer ist es möglich, Teile mit hohen spezifischen Gewichten, beispielsweise Betonsteine, Klinker und dergleichen zu heben und zu versetzen. Dabei ist es möglich, eine Anzahl von Teilen, die bereits in einem Verlegemuster angeordnet sind, zu erfassen und ohne Verschiebung gegeneinander unter Beibehaltung des Musters zu verlegen. Das erfordert eine genügend hohe Tragkraft, die jedoch nur dann sichergestellt ist, wenn das Vakuum unter den einzelnen Saugstempeln genügend hoch ist. Es hat sich jedoch gezeigt, daß das Material von Betonteilen nicht immer die genügende Dichte aufweist, so daß das Steingefüge porös ist und Luft in erheblichem Maße durchläßt. Besonders schlecht abbindendes Betonmaterial führt zu porösem Steingefüge, das dann die Ausbildung eines genügenden Vakuums verhindert. Betonhersteller sind jedoch nicht immer in der Lage, derartige Mängel zu beheben, da das Abbinden der Betonteile von der Feuchtigkeit der Umgebungsluft in erheblichem Maße beeinflußt wird.The suction gripper mentioned above makes it possible to lift and move parts with high specific weights, such as concrete blocks, clinker bricks and the like. This makes it possible to grasp a number of parts that are already arranged in a laying pattern and to lay them without shifting against each other while maintaining the pattern. This requires a sufficiently high load-bearing capacity, which can only be ensured if the vacuum under the individual suction stamps is high enough. However, it has been shown that the material of concrete parts does not always have sufficient density, so that the stone structure is porous and allows air to pass through to a large extent. Concrete material that sets particularly poorly leads to a porous stone structure, which then prevents the formation of a sufficient vacuum. However, concrete manufacturers are not always able to remedy such defects, since the setting of the concrete parts is significantly influenced by the humidity of the ambient air.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit einem Sauggreifer der eingangs genannten Art so auszugestalten, daß Teile aus Beton mit einem porösen Gefüge ohne Erhöhung der Saugleistung erfaßt und gehoben werden können.The invention is based on the object of designing a device with a suction gripper of the type mentioned above in such a way that parts made of concrete with a porous structure can be grasped and lifted without increasing the suction power.

Die erfindungsgemäße Lösung zeichnet sich dadurch aus, daß die Saugöffnungen benachbarter Saugstempel in einen auf die Oberfläche des zu hebenden Gutes aufsetzbaren Saugraum mit gemeinsam wirkender Saugfläche münden. Hierdurch wird erreicht, daß der Raum zwischen den einzelnen Saugstempeln erfaßt und in die jeweils wirksamen Saugräume der Saugstempel mit einbezogen werden kann und daß dadurch die Saugkraft ohne Erhöhung der Saugleistung der Vakuumpumpen vergrößert wird. Die Verbindung wenigstens zweier benachbarter Saugstempel durch einen Saugschuh mit gemeinsamen Saugraum reicht aus, um beispielsweise die bisher von zwei Saugstempeln erfaßten, jedoch nicht anhebbaren Betonteile poröser Struktur heben zu können.The solution according to the invention is characterized in that the suction openings of adjacent suction stamps open into a suction chamber that can be placed on the surface of the material to be lifted and has a jointly acting suction surface. This ensures that the space between the individual suction stamps can be grasped and included in the respective effective suction chambers of the suction stamps and that the suction force is thereby increased without increasing the suction power of the vacuum pumps. The connection of at least two adjacent suction stamps by a suction shoe with a joint suction chamber is sufficient to be able to lift, for example, concrete parts with a porous structure that were previously grasped by two suction stamps but could not be lifted.

Besonders günstig hat sich die Anordnung von Verbindungsöffnungen zwischen dem Saugraum und den Saugstempeln durch Luftdurchtrittsöffnungen erwiesen, deren Durchmesser wesentlich kleiner als die Durchmesser der Anschlußstutzen für die Saugstempel gehalten ist. Sofern die Luftdurchtrittsöffnungen so nahe an die Oberfäche des zu hebenden Gutes herangeführt werden, daß diese in den unmittelbaren Bereich erhöhter Strömungsgeschwindigkeit beim Durchtritt der Luft gelangen, wird die Tragfähigkeit bei porösem Steinmaterial weiter erhöht.The arrangement of connecting openings between the suction chamber and the suction rams using air passage openings whose diameter is considerably smaller than the diameter of the connecting pieces for the suction rams has proven particularly advantageous. If the air passage openings are placed so close to the surface of the material to be lifted that they reach the immediate area of increased flow velocity when the air passes through, the load-bearing capacity of porous stone material is further increased.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt und nachstehend erläutert.An embodiment of the invention is shown schematically in the drawing and explained below.

Fig. 2 die Draufsicht auf den Saugschuh gemäß Fig. 1. Fig. 2 shows the top view of the suction shoe according to Fig. 1.

Der Saugschuh 1 des Saugggreifers besteht aus einer Platte 2, deren Unterseite eine flächige Vertiefung 3 zur Bildung eines Saugraumes aufweist. Die Vertiefung 3 wird durch den durchgehenden Absatz 4 der Platte 2 gebildet. Über Durchtrittsöffnungen 5 ist die Vertiefung mit den Saugstempeln 6 verbunden. Zur Befestigung der Saugstempel am Saugschuh dienen Anschlußstutzen 7, die mit Umlaufnuten 8 versehen sind, um die formschlüssige Verbindung mit dem faltenbalgförmigen Saugstempel 6 zu ermöglichen. An der Unterseite des Saugschuhes ist ferner eine Nut 9 zur Aufnahme einer Dichtlippe 10 aus elastomerem weichen Material vorgesehen. Der Hohlraum 3 in Verbindung mit der Dichtlippe 10 bildet den gesamten Saugraum des Saugschuhes.The suction shoe 1 of the suction gripper consists of a plate 2 , the underside of which has a flat recess 3 to form a suction chamber. The recess 3 is formed by the continuous shoulder 4 of the plate 2. The recess is connected to the suction stamps 6 via through-openings 5. The suction stamps are attached to the suction shoe by connecting pieces 7 , which are provided with circumferential grooves 8 in order to enable a positive connection with the bellows-shaped suction stamp 6. A groove 9 is also provided on the underside of the suction shoe to accommodate a sealing lip 10 made of soft elastomer material. The cavity 3 in conjunction with the sealing lip 10 forms the entire suction chamber of the suction shoe.

Durch Anschrägungen 11 wird eine düsenähnliche Gestaltung der Durchtrittsöffnungen 5 erreicht, in deren Wirkungsbereich eine zusätzliche Druckabsenkung mit einer Erhöhung der Tragkraft erreicht wird.By means of bevels 11, a nozzle-like design of the passage openings 5 is achieved, in whose area of action an additional pressure reduction with an increase in the load-bearing capacity is achieved.

Aus der Gesamtdarstellung ist leicht erkennbar, daß der Zwischenraum zwischen zwei Saugstempeln fast vollständig in die Saugwirkung mit einbezogen und die wirksame Saugfläche erheblich vergrößert wird, ohne die Vakuumleistung der Saugpumpen erhöhen zu müssen.From the overall view it is easy to see that the space between two suction pistons is almost completely included in the suction effect and the effective suction area is considerably increased without having to increase the vacuum performance of the suction pumps.
