Description

Der Diagonalgreifer ist eine Vorrichtung, die in Verbindung mit einem Hebezeug bekannter Art senkrecht stehende, zu waagerechten Stapelreihen aneinandergereihte druckempfindliche Güter, wie z. B. Dachziegel, ohne diese zu .pressen, aufnehmen und lückenlos absetzen kann. Derartige Greifer besitzen einseitige Tragarme: und daran angelenkte Haltearme, die mittels an ihnen angebrachter Schienen das Ladegut halten.The diagonal gripper is a device that, in connection with a hoist of known type vertically standing pressure-sensitive goods lined up in horizontal rows of stacks, such as z. B. roof tiles, without pressing them to. Such grippers have unilateral support arms: and articulated thereon Holding arms that hold the load by means of rails attached to them.

ίο Es sind Greifvorrichtungen bekannt, die eigens für deren Größe vorgerichtete Packen aufnehmen, indem sie diese seitlich so pressen, daß ihr Gewicht getragen wird. Auch sind solche bekannt, die mit Zinken oder Spitzen das Ladegut erfassen. Beideίο There are gripping devices known that specifically Take packs prepared for their size by pressing them sideways so that their weight will be carried. Also known are those that grasp the load with prongs or points. Both

sind aber für die Aufnahme von zerbrechlichem oder hartem Ladegut, wie z. B. Dachziegel, die wegen ihrer ungleichmäßigen Form zwischen sich Lufträume einschließen und dadurch die Stapel druckempfindlich machen, nicht geeignet.but are for the inclusion of fragile or hard cargo, such as. B. roof tiles that because of their irregular shape include air spaces between them and thereby the stacks make pressure sensitive, not suitable.

Die Erfindung besteht darin, daß die an den Tragarmen angebrachte Schiene zum Unterfassen des Ladegutes als Winkelschiene ausgebildet ist und zur Begrenzung der Pressung Mittel vorgesehen sind, die die gegenseitige- Bewegung der Tragarme zu den Haltearmen begrenzen.The invention consists in that the rail attached to the support arms to be gripped under of the cargo is designed as an angle rail and means are provided to limit the pressure are that limit the mutual movement of the support arms to the support arms.

Die Greifvorrichtung nach der Erfindung ist in der Lage, waagerecht liegende Stapelreihen aus senkrecht zusammengesetzten Einzelstücken quadratischer oder rechteckiger Form, insbesondere Dachziegel, ohne diese zui pressen, aufzunehmen und zu der Länge nach lückenlosen, der Breite und Höhe nach durch Packleisten getrennte Stapel üblicher Form zusammenzusetzen und von diesen aus wieder Stapelreihen abzuheben, die der Länge oder Breite einer Ladefläche entsprechen. Dadurch ist ein wesentlicher Vorteil erreicht, der sich in einer durchgreifenden Rationalisierung gegenüber der bisherigen Arbeitsaufwendung bei der Sortierung, Stapelung der verschiedenen Klassen und Verladung von druckempfindlichen Massengütern wie Dachziegel auswirkt. Außer der Handarbeit der Sortierung, die für die Einsatzmöglichkeit des Diagonalgreifers auf ein Band oder einen Kettentransport oder eine einfache Sortierbank erfolgt, übernimmt der Diagonalgreifer alle weitere übliche Stapelung und stoßgerechte' Verladung. Die für den Diagonalgreifer notwendige Energie steht in keinem Verhältnis zu den für diese Arbeiten von Hand notwendigen Arbeitskräften und Arbeitsstunden. The gripping device according to the invention is capable of horizontally lying rows of stacks vertically assembled individual pieces of square or rectangular shape, in particular Roof tiles without pressing these zui, to take up and to the length according to the gapless, the width and Assemble height according to the stacks of the usual shape separated by packing strips and from these lift off rows of stacks that correspond to the length or width of a loading area. This is a significant advantage achieved, which is in a thorough rationalization compared to the previous amount of work involved in sorting, stacking the various classes and loading of pressure-sensitive bulk goods such as roof tiles. Besides the handicraft of the Sorting that allows the diagonal gripper to be used on a belt or chain transport or a simple sorting bank takes place, the diagonal gripper takes over all other usual tasks Stacking and load-appropriate loading. The energy required for the diagonal gripper is in no relation to the manpower and working hours necessary for this work by hand.

Die Zeichnung zeigt einen Diagonalgreifer in Perspektive (Abb.i) bzw. im Querschnitt (Abb. 2). Je nach der Länge des Greifers (z. B. 6 m) sind mehrere Tragarme 1 mit einer Tragschiene 2 und der Hebeschiene 6 verbunden, desgleichen die Haltearme 3 mit der Halteschiene 4. Die Haltearme 3 sind bei 5 an den Tragarmen 1 angelenkt. The drawing shows a diagonal gripper in perspective (Fig.i) or in cross section (Fig. 2). Depending on the length of the gripper (e.g. 6 m) are several support arms 1 with a support rail 2 and the lifting rail 6 is connected, as are the holding arms 3 with the holding rail 4. The holding arms 3 are hinged to the support arms 1 at 5.

Dadurch ist der Abstand zwischen Tragschiene 2 und der Halteschiene 4 veränderlich und ist in seinem größten/ Abstand durch die Verriegelung 10 feststellbar. Der Greifer kann so über die Stapelreihe gelegt werden, die Verriegelung 10 wird gelöst, beim Anheben der Hebeschiene 6 wird die Tragschiene 2 unter die Stapelreihe geschoben, und zwar in den Spalt, der durch die Packleisten gegeben ist, oder bei manchen Dachziegelformen, z. B. Dachpfannen, unter die ausgesparte Ecke. Beim Aufheben hängt die erfaßte Stapelreihe im Greifer, d. h., jedes erfaßte Stück liegt auf der Tragschiene 2 und wird an der Halteschiene 4 abgestützt. Durch eine eventuell verstellbare Be-' grenzungseinrichtung 8 wird ein Druck auf das Ladegut vermieden.As a result, the distance between the support rail 2 and the holding rail 4 is variable and is shown in FIG its largest / distance can be determined by the lock 10. The gripper can move over the row of stacks are placed, the lock 10 is released, when the lifting rail 6 is raised, the Support rail 2 pushed under the stack row, in the gap given by the packing strips is, or in some roof tile shapes, e.g. B. roof tiles, under the recessed corner. When picked up, the captured row of stacks hangs in the gripper, i. that is, each captured piece lies on top of the Support rail 2 and is supported on retaining rail 4. A possibly adjustable loading ' limiting device 8, pressure on the cargo is avoided.

Der nach dem Absetzen der Stapelreihe sich durch das größere Gewicht der Hebeschiene mit Aufhängung gegenüber der Tragschiene selbsttätig öffnende Greifer wird nun durch die Verriegelung 10 in dieser Lage festgehalten und so von der abgesetzten Stapelreihe abgehoben und kann auf die nächste aufgesetzt werden.The one after the stacking row has been set down automatic due to the greater weight of the lifting rail with suspension compared to the mounting rail The opening gripper is now held in this position by the lock 10 and is thus detached from the The stack row is lifted and can be placed on the next one.

Um dia senkrechte Lage der Halteschiene 4 auch beim leeren, geöffneten Greifer zu erreichen, wird das Übergewicht der Trag- gegenüber der Halteseite durch die Abstützung 9 an den Aufhänger 7 übertragen. Die Dreiecksaufhängung bekannter Art ist mit einer Feststellvorrichtung auf der Heber schiene 6 zum Aufsuchen des Lastmittels verschiebbar und feststellbar.In order to achieve the vertical position of the holding rail 4 even when the gripper is empty, open the excess weight of the carrying side compared to the holding side due to the support 9 on the hanger 7 transfer. The triangular suspension of the known type is with a locking device on the jack Rail 6 to find the load means displaceable and lockable.

Eine einfache Scharnierklappe bekannter Art, die beim Aufsetzen des Greifers nach oben ausweicht und beim Anheben über das letzte vom Greifer erfaßte Stück fällt, verhindert dessen Herausfallen aus dem Greifer, da die die Stapelreihen bildenden Einzelstücke zum Zwecke ihrer Standfestigkeit meist nicht ganz senkrecht, sondern etwas angelehnt aneinandergeschichtet werden..A simple hinged flap of a known type that moves upwards when the gripper is put on and when lifting falls over the last piece gripped by the gripper, prevents it from falling out from the gripper, as the individual pieces forming the stack rows for the purpose of their stability are usually not completely vertical, but are stacked a little leaning against each other ..
