    Multi-shell gripper for lumpy stored goods
    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.
    In general, grippers are load handling devices with movable gripper shells, which means are known in various embodiments to a person skilled in the art.
    A movement or opening and closing of the gripper shells can be done by means of cables or hydraulically effected.
    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, 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 grippers can be designed as a two-shell or as a multi-shell gripper, wherein for bulky scrap mostly a polygonal or finger gripper comes with in the lower area adjacent shells used.
    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.
    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. Mm mm m m m m m mm m mm mm m m mm mm mm mm m m mm mm
    The invention now aims to form a multi-shell gripper of the type mentioned above, so that during the picking and / or a transfer of the bulky stored goods a compaction of the same takes place.
    Preferably, this gripper training should be able to separate a projecting between the shells Good.
    This object is achieved in a generic multi-shell gripper characterized in that the traverse 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 Druckstablagem rotatably mounted on substantially triangular Druckübersetzerteilen 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.
    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, especially of bulky scrap. On the other hand, the angular gripping means are on one hand rotatably fixed to triangular pressure booster parts, on the other hand, a holder is spaced apart via pressure rods on pressing means. Pressure means for the position of the gripping means are effective between truss part and pressure booster part.
    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 Greifschaien, wherein at least a partial closing of the same takes place.
    As a result, the pressing means with the press die hydraulically becomes 2... +...
    Shell cavity moved towards and precompressed so the stored material in the gripper. A lowering of the ram causes further that the pressure rods move the connecting bearing with the gripping means to the outside, resulting in a kind of toggle action by which the hook shells subjected to significantly increased, centering pressure and the stored goods are further compressed transversely to the ram.
    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.
    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.
    Advantageously, the edges of the gripper shells, at least in the area in which these abut each other 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.
    In the following the invention will be explained in more detail with reference to drawings showing only one embodiment.
    It shows each in a schematic representation
    Fig. 1 shows a multi-shell gripper with open gripping means
    Fig. 2 shows a multi-shell gripper with largely closed gripping means
    Fig. 3 shows a multi-shell gripper with compacted stored goods
    Fig. 4 shows a multi-shell gripper in an oblique view
    In order to facilitate an assignment of the parts in the figures, a reference list is given below. 3

    In Fig. 1, an inventive multi-shell gripper is shown in a position with spread gripping means 1.
    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 an applied position of the gripper on a stored material S is an activation of pressure means 8, wherein, as shown in Fig. 2, gripping means 1 are symmetrically exposed by a pressure on bearings 81 on the pressure booster part 2 a rotational or closing moment, which from the Distance from the pressure medium bearing 81 to the pressure storage 6, which is stabilized by a stop 41 results. 4 * # ·····································································································································································································
    Ultimately, a stored product S is taken in the gripper shell cavity.
    Subsequently, as is finally apparent from FIG. 3, a pressing and holding means 31 are moved in a piston of a traverse part 3 with a press die 9 towards the gripper cup cavity, whereby compaction of the stored material S takes place in the axial direction. At the same time support bearing 32 are spent on the pressing and holding member 31 in the axial direction, via these support bearing 32 on the push rods 4 by their inclination against the pressing direction, a force is buildable, which acts on the pressure bearing 6 of the gripping means 1 and this by 10 by extended Pressure fluid 8 stabilized bearing 7 in the pressure booster part 2, which bearing 5 (Fig. 4) rotatably in communication with the truss member, 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. 15
