Wie aus den Fig. 1 bis 4 ersichtlich, weist die erfindungsgemäße Lösung eine Transporteinrichtung 1 auf, welche aus einem schienengeführten Portalarm 2 und an dessem freien Ende vorgesehene, durch Druckmittel höhenverstell- sowie betätigbaro Greifer 3 besteht. Weiterhin sind beidseitig des zu bildenden Stapels vordere Träger 4 und hintere Träger 4' vorgesehen. Jedes Trägerpaar 4,4' nimmt oberhalb der Ablageebene 5, die aus Transportpalette 6 und gegebenenfalls abgelegten Restgittern 7 gebildet ist, einen flächigen und über die gesamte Länge der Ablageebene 5 reichenden Kippflügel 8 auf, deren Schwenkachse 9 in Richtung des durch die Endstellung der Transporteinrichtung 1 gemäß Fig.2 markierten Auslaufendes 10 unter dem Winkel β von etwa 5 bis 10 Grad steigend angeordnet ist. Des weiteren sind die Kippflügel 8 derart ausgeführt, daß sie sich in Aufzugsrichtung des Restgitters 7 unter dem Winkel α von etwa 5 bis 10 Grad verbreitern. Mittels der Antriebe 11 sind die Kippflügel 8 von der horizontalen Ausgangsstellung gemäß Fig. 1 bis 3 in die vertikale Lage gemäß Fig. 4 klappbar. Die erfindungsgemäße Einrichtung arbeitet wie folgt:As can be seen from FIGS. 1 to 4, the solution according to the invention comprises a transport device 1, which consists of a rail-guided portal arm 2 and provided at its free end, by means of pressure medium höhenverstell- and actuatable gripper 3. Furthermore, front supports 4 and rear supports 4 'are provided on both sides of the stack to be formed. Each pair of supports 4,4 'takes above the storage level 5, which is formed from transport pallet 6 and optionally stored waste grids 7, a flat and over the entire length of the storage level 5 reaching tipping wings 8, the pivot axis 9 in the direction of the end of the transport device 2 marked outlet end 10 is arranged at an angle β of about 5 to 10 degrees rising. Furthermore, the tilting wings 8 are designed such that they widen in the elevator direction of the residual grid 7 at the angle α of about 5 to 10 degrees. By means of the drives 11, the tilting wings 8 can be folded from the horizontal starting position according to FIGS. 1 to 3 into the vertical position according to FIG. 4. The device according to the invention operates as follows:

Das Restgitter 7 wird durch die Greifer 3 auf dem Bearbeitungstisch 12 einer nicht näher dargestellten Bearbeitungsmaschine erfaßt und mittels der Transporteinrichtung 1 über die in horizontaler Ausgangsstellung befindlichen, zueinander gerichteten Kippflügel 8 bis an das Auslaufende 10 der Einrichtung gezogen. Auf Grund der geneigten Schwenkachsen 9 der Kippflügel 8 und dessen Verjüngungen beginnt sich das Restgitter 7 durch die Schwerkraft zwischen den Trägern 4 mittig abzusenken. Dieser Effekt wird durch das gesteuerte Abklappen der Kippflügel 8 mittels der Antriebe 11 und dem koordinierten Absenken der Greifer 3 verstärkt, wobei das Restgitter 7 zwischen den Trägern 4 beginnend allmählich in Richtung der Träger 4' auf die Ablageebene 5 gestapelt und in der Endphase des Stapelprozesses durch die Greifer 3 freigegeben wird. Die an den freien Enden der Kippflügel 8 vorgesehenen abgerundeten Kanten unterstützen den Abgleitvorgang des Restgitters 7, so daß auch beim Vorhandensein der Durchbrüche und scharfen Kanten ein Hängenbleiben der Werkstücke im Prozeß ausgeschlossen bleibt. Die Neigung der Schwenkachsen 9 unterstützt einerseits das Absenken des Restgitters 7 und dient andererseits dazu, die Verjüngungen der Kippflügel 8 derart zu kompensieren, daß sich dessen Kanten im Absenkprozeß immer parallel zur Ablageebene 5 befinden und eine maximale Ausnutzung der Stapelhöhe gewährte stet wird. Nach erfolgter Ablage des Restgitters 7 auf den Stapel der Transportpalette 6 werden die Kippflügel 8 bei gleichzeitiger Anhebung der Greifer 3 wieder in die horizontale Ausgangsstellungslage geschwenkt. Die Transporteinrichtung 1 fährt vom Auslaufende 10 mit geöffnetem Greifer 3 zum Bearbeitungstisch 12 zurück, erfaßt das nächste Restgitter 7 und bringt dieses wie bereits beschrieben zurAblage. Über an sich bekannte elektrische Tast- und Schalteinheiten werden die einzelnen Funktionsschritte der Einrichtung eingeleitet und überwacht.The skeleton grid 7 is detected by the gripper 3 on the working table 12 of a processing machine, not shown, and pulled by means of the transport device 1 on the located in the horizontal starting position, facing each other tilting wing 8 to the outlet end 10 of the device. Due to the inclined pivot axes 9 of the tilting wings 8 and its tapers, the skeleton grid 7 begins to lower centrally by gravity between the carriers 4. This effect is enhanced by the controlled folding of the tilting wings 8 by means of the drives 11 and the coordinated lowering of the gripper 3, wherein the residual grid 7 is gradually stacked between the carriers 4 in the direction of the carrier 4 'on the storage level 5 and in the final phase of the stacking process is released by the gripper 3. The provided at the free ends of the flipper 8 rounded edges support the sliding of the residual grid 7, so that even in the presence of breakthroughs and sharp edges snagging of the workpieces remains excluded in the process. The inclination of the pivot axes 9 on the one hand supports the lowering of the residual grating 7 and on the other hand serves to compensate for the tapering of the tilting wings 8 such that its edges are always parallel to the storage level 5 in the lowering process and maximum utilization of the stack height is granted. After the storage of the residual grid 7 on the stack of transport pallet 6, the tilting wings 8 are pivoted at the same time raising the gripper 3 back into the horizontal position of initial position. The transport device 1 travels from the outlet end 10 with open gripper 3 back to the processing table 12, detects the next skeleton grid 7 and brings this as already described to the storage. About known per se electrical sensing and switching units, the individual functional steps of the device are initiated and monitored.

Field of application of the invention

The invention relates to a device for stacking openwork, flat piece goods, in particular of skeletons after

Punching operations consisting of a transport device, parallel to each other and arranged above the stack to be formed on carriers, flat Abklappelemente which are pivotable by means of drive from a rest grid supporting the holding position in its release position, and a storage level.

Characteristic of the known technical solutions

It is already a device for dispensing of metal sheets on stacking pallets (DD 238929) is known, in which the sheet metal to be stacked between upper strand and lower strand of a non-moving endless chain conveyor is fed resting on the lower strand, the lower strand as a supporting conveying surface, for example as a between the transport chains hanging runway, and the upper strand is designed as a diarrhea. By a drive, the runway is moved against the feed direction of the starting position in the lower strand to an end position in the upper strand and thus the metal sheet, based on the last role in Untertrum or held down by the first role in the upper strand, stored in an inclined position on a stack pallet.

Furthermore, a device for stacking plates on a movable from a receiving station to a workstation work table (DE 2347643) is known, which provides storage shelves as storage members, which extend in the storage position below the longitudinal sides of the intermediate stack and are laterally pivotable for lowering the intermediate stack. Furthermore, a stacking device for sheet metal plates (DE 2811571) is known, which consists of a transport device and arranged at the outlet end, lowerable device for depositing the sheets on a storage level above the stack to be formed on side supports two parallel, rotatably mounted by pivot arms Rolling rows whose roles have a cambered surface and are mounted on vertically or inclined to the storage level arranged pivot axes, provides. Here, the plates are lowered by the pivoting of the rollers and stacked when reaching the position B in free fall.

Furthermore, a sheet stacking device (SU 1289916) is known, which is formed of two, attached to guides horizontally movable beams, a lifting table for stacking sheets and transport rollers with rotary drive and folding device and at least one pair of pinch rollers with inclined surface line. With this device, the stacking of the sheets takes place in such a way that only takes place by folding down the transport rollers in the vertical position of the sheet ejection to the storage level.

All the devices described has the disadvantage that they are not suitable for stacking open-plan, sheet materials, for example, provided with bumps skeletons after punching operations. The latter three solutions also have the disadvantage that when using materials of different width and stiffness, a constant adjustment of the roles or the strips is required.
