Description

meinsamen Bewegung der Zugmittel sind diese über Kupplungen miteinander antriebsverbindbar. Hierdurch ist es möglich, nach dem Belegen eines Trägers diesen synchron mit demjenigen Träger in die Presse zu bewegen, der aus der Presse heraus bewegt wird.joint movement of the traction means, these can be driven to one another via clutches. Through this it is possible, after a carrier has been occupied, to put it in the press synchronously with that carrier to move, which is moved out of the press.

Die Erfindung wird im folgenden an Hand des in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es ist dargestellt inThe invention is described below with reference to the exemplary embodiment shown in the drawings explained in more detail. It is shown in

F i g. 1 eine erfindungsgemäße, an einer Presse angeordnete Beschickvorrichtung in Seitenansicht,F i g. 1 an inventive, arranged on a press Loading device in side view,

F i g. 2 und 3 zwei weitere Stellungen der Beschickvorrichtung in Darstellungen gemäß F i g. 1 undF i g. 2 and 3 two further positions of the loading device in representations according to FIG. 1 and

F i g. 4 eine Draufsicht auf die Darstellung gemäß F i g. 2 ohne Presse.F i g. 4 shows a plan view of the illustration according to FIG F i g. 2 without press.

Wie die F i g. 1 bis 4 zeigen, weist die Beschickvorrichtung zwei als Förderblätter ausgebildete Träger 1 und 2 für Werkstücke 3, wie beispielsweise Spanformlinge bzw. Spanplatten od. dgl., auf. Die Träger 1 und 2 sind hintereinanderliegend entlang identischen Bewegungsbahnen 4 geführt, die durch Umlenkrollen 5 bzw. 6 festgelegt sind.As the F i g. 1 to 4 show, the loading device has two carriers 1 designed as conveyor blades and 2 for workpieces 3, such as chip moldings or chipboard or the like. The carriers 1 and 2 are guided one behind the other along identical movement paths 4, which are determined by pulleys 5 or 6 are set.

Auf jeder Seite der Träger 1 und 2 sind jeweils zweiüber die Umlenkrollen 5 bzw. 6 umlaufend geführte Zugmittel 7 bzw. 8 in Form von Seilen, Ketten od. dgl. vorgesehen. Die beiden äußeren Zugmittel 7, die über die Umlenkrollen 5 geführt sind, sind dem einen Träger 1 zugeordnet, der an diesen Zugmitteln 7 mit entsprechenden Verbindungsgliedern 9 befestigt ist. An den inneren Zugmitteln 8, die über die Umlenkrollen 6 geführt sind, ist der andere Träger 2 mit entsprechenden Verbindungsgliedern 10 befestigt.On each side of the beams 1 and 2 are two over each the pulleys 5 or 6 circumferentially guided traction means 7 or 8 in the form of ropes, chains or the like. intended. The two outer traction means 7, which are guided over the pulleys 5, are the one carrier 1, which is attached to these traction means 7 with corresponding connecting links 9. On the inner traction means 8, which are guided over the pulleys 6, is the other carrier 2 with corresponding Connecting links 10 attached.

Die sich entsprechenden Umlenkrollen 5 und 6 der beiden Zugmittel 7 und 8 liegen koaxial zueinander.The corresponding deflection rollers 5 and 6 of the two traction means 7 and 8 are coaxial with one another.

Wie die F i g. 1 bis 3 ferner zeigen, ist das Obertrum 11 der Bewegungsbahn 4 durch eine Presse 13 zwischen deren Tisch 14 und deren Pressenstempel 15 hindurchgeführt. Das untere Trum 12 der Bewegungsbahn 4 befindet sich unterhalb des Pressentisches 14. Bei der in F i g. 1 dargestellten Stellung befindet sich der eine Träger 1 in der Presse 13 bei geschlossenem Pressenstempel 15. Der andere Träger 2 befindet sich im Bereich der in Bewegungsrichtung Pfeil 16 der Träger 1 und 2 vor dem Träger 1 liegenden, vom Untertrum 12 zum Obertrum 11 führenden Umlenkung, die von dem Pressentisch 14 einen der Länge des Trägers 1 bzw. 2 etwa entsprechenden Abstand hat. In unmittelbarer Nähe dieser Umlenkung wird das im Bereich des Obertrums 11 der Bewegungsbahn 4 liegende Teil des Trägers 2 mit Werkstücken 3 belegt, wobei der Träger 2 unabhängig vom Träger 1 nach und nach in die Stellung gemäß F i g. 2 bewegt wird. Nach Öffnen der Presse 13 gemäß F i g. 2 werden die Zugmittel 7 und 8 über nicht näher dargestellte, beispielsweise koaxial zu den Umlenkrollen 5 und 6 liegende Kupplungen miteinander gekuppelt, so daß der Träger 1 mit den fertig bearbeiteten Werkstücken in Pfeilrichtung 16 aus der Presse 13 und der Träger 2 mit den noch nicht bearbeiteten Werkstücken 3 synchron zum Träger 1 in die Presse 13 gemäß F i g. 3 bewegt wird. Der Träger 1 übergibt im Bereich der in Bewegungsrichtung Pfeil 16 hinter der Presse 13 liegenden, vom Obertrum 11 zum Untertrum 12 führenden Umlenkung, die fertig bearbeiteten Werkstücke 3 an eine geeignete, beispielsweise Rollen 19 aufweisende Vorrichtung 18 und wird unterhalb des Pressentisches 14 zurückbewegt, so daß dieser Träger 1 nunmehr während des Preßvorganges der auf dem Träger 2 befindlichen Werkstücke in der beschriebenen Weise mit noch nicht bearbeiteten Werkstücken belegt werden kann. Beim Belegen des Trägers 1 bzw. 2 wird dieser kontinuierlich oder schrittweise entsprechend der Werkstückgröße bzw. -art zur Presse 13 hin bewegt.As the F i g. 1 to 3 also show the upper run 11 of the movement path 4 through a press 13 passed between the table 14 and the press ram 15. The lower run 12 of the movement path 4 is located below the press table 14. In the case of the in FIG. 1 is the position shown one carrier 1 in the press 13 when the press is closed Press ram 15. The other carrier 2 is located in the area of arrow 16 in the direction of movement Carrier 1 and 2 in front of carrier 1, deflection leading from lower run 12 to upper run 11, which has a distance approximately equal to the length of the carrier 1 or 2 from the press table 14. In In the immediate vicinity of this deflection, the one located in the area of the upper run 11 of the movement path 4 becomes Part of the carrier 2 covered with workpieces 3, the carrier 2 according to independently of the carrier 1 and after in the position according to FIG. 2 is moved. After opening the press 13 according to FIG. 2 will be the Traction means 7 and 8 via not shown, for example lying coaxially to the pulleys 5 and 6 Couplings coupled together so that the carrier 1 with the finished workpieces in Direction of arrow 16 from the press 13 and the carrier 2 with the not yet machined workpieces 3 synchronously to the carrier 1 in the press 13 according to FIG. 3 is moved. The carrier 1 transfers in the area of in Direction of movement arrow 16 lying behind the press 13, leading from the upper run 11 to the lower run 12 Deflection, the finished workpieces 3 to a suitable one, for example having rollers 19 Device 18 and is moved back below the press table 14, so that this carrier 1 is now during the pressing process of the workpieces located on the carrier 2 in the described Way can be occupied with not yet machined workpieces. When occupying carrier 1 or 2 this is continuously or step by step according to the workpiece size or type towards the press 13 emotional.
