Stoppers (21) at the pressure transformation parts limit a pivot movement of the gripping units. Other stoppers (41) limit a pivot movement of pressure rods (4) at the traverse part. A pressing plunger (9) is provided by the traverse part perpendicular to a jaw cavity of the gripper.

Description

Die Erfindung bezieht sich auf einen Mehrschalen-Greifer für stückiges Lagergut, insbesondere auf einen hydraulischen bzw. einen Motor-Greifer für sperrigen Schrott, beinhaltend ein, vorzugsweise über ein Lastaufnahmemittel mit einer Krankatze verbundenes, Traversenteil, über Drehgelenke gelagerte Greifmittel sowie Druckmittel zur Stellung bzw. Anstellung oder zum Schließen von Greifmitteln.The invention relates to a multi-shell gripper for lumpy stored goods, in particular a hydraulic or a motor gripper for bulky scrap, including a, preferably via a load-carrying means connected to a crane trolley, mounted on pivoting jaws gripping means and pressure means for position or Employment or closing of gripping means.

Generell sind Greifer Lastaufnahmemittel mit bewegbaren Greiferschalen, welche Mittel in verschiedenen Ausführungsformen einem Fachmann bekannt sind.In general, grippers are load-carrying means with movable gripper shells, which means are known in various embodiments to a person skilled in the art.

Eine Bewegung bzw. ein Öffnen und Schließen der Greiferschalen kann mittels Seilzügen erfolgen oder hydraulisch bewirkt werden.A movement or opening and closing of the gripper shells can be done by means of cables or hydraulically effected.

Ist für ein Öffnen und Schließen der Greiferschalen ein greiferinternes, elektrohydraulisches Aggregat vorgesehen, welches über eine Leitungstrommel mit Energie versorgt, sowie gesteuert wird, so bezeichnet der Fachmann dieses Lastaufnahmemittel als Motor-Greifer, welcher in einfacher Weise in ein Stückguthubwerk eingehängt werden kann.If a gripper-internal, electro-hydraulic unit is provided for opening and closing the gripper shells, which is supplied with energy via a line drum and controlled, then the person skilled in the art refers to this load handling device as a motor gripper, which can be easily hooked into a piece gripper.

Motor-Greifer können als Zweischalen- oder als Mehrschalen-Greifer ausgeführt sein, wobei für sperrigen Schrott zumeist ein Polygonal- oder Finger-Greifer mit im unteren Bereich aneinander anliegenden Schalen zum Einsatz kommt.Motor grippers can be designed as a two-shell or as a multi-shell gripper, with bulky scrap usually having a polygonal or finger gripper with adjoining shells being used in the lower region.

Alle mehrschaligen Greifer für stückiges Lagergut haben den Nachteil gemeinsam, dass ein sperriges Gut, wie sperriger Schrott, zwar das Schalenvolumen füllend gehoben werden kann, jedoch das Füllgewicht je Fassung gering ist. Für eine Weiterverarbeitung erfolgt zumeist eine Kompaktierung des Satzes in einer eigenen Einrichtung, was sich beispielsweise bei einem Chargieren eines Schmelzgefäßes als großer, wirtschaftlicher Mangel darstellt.All multi-shell gripper for lumpy storage goods have the common drawback that a bulky good, such as bulky scrap, while the shell volume can be lifted filling, but the filling weight per version is low. For further processing is usually a compaction of the sentence in a separate institution, which is, for example, when charging a melting vessel as a major economic shortcoming.

Andererseits ragen gegebenenfalls zwischen den Greiferschalen Teile der Last bzw. vom Schrott ab, was wiederum beim Chargieren hinderlich sein kann.On the other hand, possibly protrude between the hook shells parts of the load or from the scrap, which in turn can be a hindrance during charging.

Die Erfindung zielt nun darauf ab, einen Mehrschalen-Greifer der eingangs genannten Art derart auszubilden, sodass während des Aufgreifens und/oder eines Verbringens des sperrigen Lagergutes eine Kompaktierung desselben erfolgt.The invention now aims to a multi-shell gripper the above mentioned type such that during the picking up and / or a transfer of the bulky stored goods a compaction of the same takes place.

Bevorzugt soll diese Greiferausbildung ein zwischen den Schalen ausragendes Gut abtrennen können.Preferably, this gripper training should be able to separate a projecting between the shells Good.

Dieses Ziel wird bei einem gattungsgemäßen Mehrschalen-Greifer dadurch erreicht, dass das Traversenteil ein axial verstellbares Press- und Haltemittel mit einem Pressstempel und zumindest auf zwei gegenüberliegenden Seiten mit Stützlagern für Druckstäbe, welche mit winkelförmigen Greifmitteln durch Lager endenseitig drehbar verbunden sind, aufweist und diese Greifmittel distanziert von den Druckstablagern drehbar an im Wesentlichen dreieckigen Druckübersetzerteilen im Bereich einer Ecke derselben befestigt sind und die Bereiche der weiteren Ecken der Druckübersetzerteile drehbar mit dem Traversenteil und mit Druckmitteln, welche sich andererseits am Traversenteil abstützen, verbunden sind, wobei an den Druckübersetzerteilen Anschläge eine Schwenkbewegung der Greifmittel und Anschläge am Traversenteil eine Schwenkbewegung der Druckstäbe begrenzen.This object is achieved in a generic multi-shell gripper characterized in that the truss part an axially adjustable pressing and holding means with a ram and at least on two opposite sides with support bearings for push rods, which are rotatably connected endwise with angular gripping means by bearings, and this Gripping means are distanced from the pressure support bearings rotatably mounted on substantially triangular pressure intensifier parts in the region of a corner thereof and the areas of the other corners of the Druckübersetzerteile rotatably connected to the truss part and with pressure means, which are supported on the other hand on the truss part, wherein at the Druckübersetzerteilen stops a Swivel movement of the gripping means and stops on the truss part limit a pivoting movement of the pressure rods.

Die mit dem erfindungsgemäßen Mehrschalen-Greifer erreichten Vorteile sind im Wesentlichen darin begründet, dass einerseits vom Traversenteil senkrecht zum Schalenhohlraum des Greifers hin wirkend ein Pressstempel vorgesehen ist, der eine Kompaktierung des Lagergutes, insbesondere von sperrigem Schrott, bewirken kann. Andererseits sind die winkelförmigen Greifmittel zum einen an dreieckigen Druckübersetzungsteilen drehbar festgelegt, zum anderen erfolgt eine Halterung beabstandet über Druckstäbe an Pressmittel. Druckmittel zur Stellung der Greifmittel sind zwischen Traversenteil und Druckübersetzerteil wirksam.The advantages achieved with the multi-shell gripper according to the invention are essentially due to the fact that on the one hand from the cross member perpendicular to the shell cavity of the gripper acting a punch is provided which can cause compaction of the stored material, in particular bulky scrap. On the other hand, the angular gripping means are on the one hand rotatably fixed to triangular pressure booster parts, on the other hand, a holder is spaced by means of pressure rods on pressing means. Pressure means for the position of the gripping means are effective between truss part and pressure booster part.

Stückiges Lagergut wird nach Aufsetzen des offenen Mehrschalen- bzw. Finger-Greifers nach der Erfindung durch Aktivierung der Druckmittel beim Schließen des Greifers bzw. der Greifschalen gefasst, wobei zumindest ein teilweises Schließen derselben erfolgt.Pieces of stored goods are taken after placing the open multi-shell or finger gripper according to the invention by activating the pressure means when closing the gripper or the gripping shells, wherein at least a partial closing of the same takes place.

In der Folge wird das Pressmittel mit dem Pressstempel hydraulisch zum Schalenhohlraum hin bewegt und derart das Lagergut im Greifer vorkomprimiert. Ein Absenken des Pressstempels bewirkt weiters, dass die Druckstäbe die Verbindungslager mit den Greifmitteln nach außen bewegen, wobei sich eine Art Kniehebelwirkung ergibt, durch welche die Greiferschalen mit wesentlich erhöhtem, zentrierendem Druck beaufschlagt und das Lagergut weiters quer zum Pressstempel komprimiert werden.As a result, the pressing means with the press ram is hydraulically moved towards the shell cavity and thus precompressed the stored material in the gripper. A lowering of the ram causes further, that the pressure rods the Move connecting bearing with the gripping means to the outside, resulting in a kind of toggle action, which acts on the gripper cups with significantly increased, centering pressure and the stored goods are further compressed transversely to the ram.

Beim Fassen des Lagerguts und beim nachfolgenden Pressvorgang erfolgt zeitweise eine einseitige Abstützung der Druckstäbe und der Druckübersetzerteile mittels Anschlägen.When grasping the stored material and during the subsequent pressing operation, there is at times a one-sided support of the pressure bars and the pressure booster parts by means of stops.

Derart ist es möglich, mit einem erfindungsgemäßen Greifer sperriges Lagergut, z.B. Schrottteile, direkt bei einem Anheben und/oder einem Verbringen durch Verringerung des Schalenhohlraumes auf ein kleineres Volumen zu verpressen und gegebenenfalls nach Öffnen ein Paket bereitzustellen.It is thus possible, with a gripper according to the invention, to store bulky stored goods, e.g. To compress scrap parts, upon lifting and / or moving, by reducing the shell cavity to a smaller volume and optionally providing a package after opening.

Mit Vorteil weisen die Kanten der Greiferschalen mindestens im Bereich, in welchem diese beim Kompaktieren aneinanderliegen oder sich überlappen, zusammenwirkende Trennmittel für überstehendes Lagergut bzw. überragenden Schrott auf. Überstehendes Lagergut, insbesondere überstehende Schrottteile, können dadurch abgetrennt und ein kompaktiertes Schrottpakte gebildet werden.Advantageously, the edges of the gripper shells, at least in the region in which these lie against one another during compacting or overlap, cooperating release agent for supernatant stored goods or outstanding scrap. Projecting stored goods, in particular protruding scrap parts, can be separated and a compacted scrap packets are formed.

Im Folgenden wird die Erfindung anhand lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.In the following the invention will be explained in more detail with reference to drawings showing only one embodiment.

In Fig. 1 ist ein erfindungsgemäßer Mehrschalen-Greifer in einer Position mit gespreizten Greifmitteln 1 dargestellt.In Fig. 1 an inventive multi-shell gripper is shown in a position with spread gripping means 1.

Eingefahrene Druckmittel 8, welche einerseits mit einem Traversenteil 3 in Verbindung stehen, halten andererseits Druckübersetzerteile 2 in einer Position fest, in welcher Greifmittel 1 festgelegt mittels Lager 7 durch Drehung um ein Lager 6 bei Stabilisierung desselben durch Anschläge 41 für Druckstäbe 4 auskragen. In einer derartigen Position wird der Greifer auf das Lagergut aufgelegt, wobei die Enden der Greifmittel in dieses eindringen.Retracted pressure means 8, which are on the one hand connected to a truss member 3, hold on the other hand Druckübersetzerteile 2 in a position fixed in which gripping means 1 by means of bearings 7 by rotation about a bearing 6 during stabilization of the same by stops 41 for push rods 4 protrude. In such a position, the gripper is placed on the stored goods, wherein the ends of the gripping means penetrate into this.

In einer aufgelegten Position des Greifers auf ein Lagergut S erfolgt eine Aktivierung von Druckmitteln 8, wobei, wie in Fig. 2 dargestellt, Greifmittel 1 durch einen Druck auf Lager 81 am Druckübersetzerteil 2 symmetrisch einem Dreh- bzw. Schließmoment ausgesetzt werden, welches aus dem Abstand vom Druckmittellager 81 zum Druckstablager 6, welches durch einen Anschlag 41 stabilisiert ist, resultiert. Letztlich ist ein Lagergut S im Greiferschalenhohlraum gefasst.In an applied position of the gripper on a stored material S is an activation of pressure means 8, wherein, as in Fig. 2 shown, the gripping means 1 will be exposed by a pressure on bearing 81 of the intensifier part 2 symmetrically to a rotational or closing moment which results from the distance from the fluid bearing 81 to the push rod bearing 6, which is stabilized by a stop 41st Ultimately, a stored product S is taken in the gripper shell cavity.

Darauffolgend kann, wie letztlich aus Fig. 3 ersichtlich ist, ein Press- und Haltemittel 31 in einem Kolben eines Traversenteiles 3 mit einem Pressstempel 9 zum Greiferschalenhohlraum hin verfahren werden, wodurch in Axrichtung eine Kompaktierung des Lagergutes S erfolgt. Gleichzeitig werden Stützlager 32 am Press- und Halteteil 31 in Axrichtung verbracht, wobei über diese Stützlager 32 auf die Druckstäbe 4 durch deren Schrägstellung gegen die Pressrichtung eine Kraft aufbaubar ist, welche auf die Druckstablager 6 der Greifmittel 1 wirkt und diese um das durch ausgefahrene Druckmittel 8 stabilisierte Lager 7 im Druckübersetzerteil 2, welches Lager 5 ( Fig. 4 ) mit dem Traversenteil drehbar in Verbindung steht, entsprechend einer sogenannten Kniehebelwirkung weiter zueinander presst. Derart kann eine weitere, im Wesentlichen quer zur Pressstempelaxe gerichtete Kompression des Lagergutes bzw. der Schrottteile erreicht werden.Subsequent, how can ultimately Fig. 3 it can be seen, a pressing and holding means 31 in a piston of a truss member 3 with a ram 9 for Claw shell cavity are moved towards, whereby a compaction of the stored material S takes place in Axrichtung. At the same time support bearing 32 are spent on the pressing and holding part 31 in the axial direction, via these support bearings 32 on the push rods 4 by their inclination against the pressing direction a force buildable, which acts on the pressure bearing 6 of the gripping means 1 and this by the extended pressure medium 8 stabilized bearings 7 in the pressure booster part 2, which bearing 5 ( Fig. 4 ) is rotatably in communication with the truss part, according to a so-called toggle action continues to press each other. In this way, it is possible to achieve a further compression of the stored goods or of the scrap parts directed essentially transversely to the ram pressure axis.
