Description

In dem Patent 874272 ist eine Vorrichtung zum Vereinzeln von Werkstücken beschrieben, bei der mittels um etwa go0 schwingende Sauger die obere Kante des untersten Werkstückes eines schräg gestellten Stapels um mitschwingende, lose laufende Rollen herumgeführt und den Transportwalzen zugeführt werden, wobei gleichzeitig schwingende Anschläge sich gegen die obere Stapelecke anlegen. In the patent 874272 there is a device for separating workpieces described, in which the upper edge of the lowest workpiece of an inclined stack around oscillating, loosely running Rolls are guided around and fed to the transport rollers, at the same time swinging stops are placed against the upper corner of the stack.

Es hat sich herausgestellt, daß auch dabei noch mitunter das nächstfolgende Werkstück mitgenommen wird, insbesondere dann, wenn die beiden Werkstücke durch Klebstoffspritzer oder an den Einschnittstellen zusammenhängen. It turned out that sometimes the next one Workpiece is taken along, especially when the two workpieces through Adhesive splashes or at the incision points.

In Weiterentwicklung der Erfindung des Hauptpatents sind die übelstände dadurch beseitigt, daß eine Abhebevorrichtung die obere Stapelunterkante während des Vereinzelus etwas anhebt und daß in den dadurch entstehenden Spalt Luft geblasen wird. The evils are a further development of the invention of the main patent thereby eliminating the need for a lifting device to lower the upper edge of the stack during of the singular lifts a little and that air is blown into the gap that is created will.

Durch das Anheben der oberen Stapelunterkante wird einmal das auf das abzuziehende bzw. abzuwälzende Werkstück wirkende Gewicht des Stapels verringert und zum anderen ein Spalt gebildet, in den nunmehr durch Düsen Luft eingeblasen werden kann, wodurch etwa zusammenhängende Teile der beiden Werkstücke getrennt werden. Auf diese Weise ist eine sichere Vereinzelung der Werkstücke von dem vorhandenen Stapel möglich.By lifting the top of the stack, this will open once the weight of the stack acting on the workpiece to be withdrawn or rolled is reduced and on the other hand, a gap is formed into which air is now blown through nozzles can be, whereby approximately contiguous parts of the two workpieces are separated will. In this way, the workpieces are reliably separated from the existing ones Stack possible.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. I die neue Vorrichtung in Seitenansicht in der Ansaugstellung des Werkstückes, Fig. 2 die Vorrichtung im Moment des Anhebens des Stapels und das Einsetzen der Blasluft. An exemplary embodiment of the invention is shown in the drawing. It shows Fig. I the new device in side view in the suction position of the Workpiece, FIG. 2 shows the device at the moment of lifting the stack and inserting it the blown air.

Nach der Erfindung sind auf einer Welle 20 Finger oder Halter 2I an Haltearmen 22 angebracht, die durch Drehung der Welle gegen die obere Unterkante des Stapels 2 stoßen und diese anheben, sobald das zu vereinzelnde Werkstück I durch die Sauger 13 umgebogen ist. Das Anheben der oberen Stapelunterkante durch die Finger 21 erfolgt im Takt der Maschine, beispielsweise dadurch, daß auf der Welle 20 ein Hebel angebracht ist, der beim Senken der Schwenkhebel 5 auf einen Anschlag stößt und dabei die Welle 20 mit den Fingern 2I in Drehung versetzt. According to the invention, fingers or holders 2I are on a shaft 20 attached to support arms 22, which by rotating the shaft against the upper lower edge of the stack 2 and lift it as soon as the workpiece I to be separated is through the suction cup 13 is bent. Lifting the top of the stack with your fingers 21 takes place in time with the machine, for example in that on the shaft 20 a Lever is attached, which hits a stop when lowering the pivot lever 5 while the shaft 20 is set in rotation with the fingers 2I.

Weiterhin sind nach der Erfindung Blasdüsen 23 an der Vorrichtung angebracht, die in den durch das Abbiegen des Stapels und dem abzuziehenden Werkstück entstehenden Spalt Luft blasen, wodurch ein sicheres Trennen des zu vereinzelnden Werkstückes vom Stapel erzielt wird. Die Blasdüsen 23 sind zweckmäßig an die Vakuumpumpe für die Sauger 13 angeschlossen, so daß die dabei komprimierte Luft verwandt wird. Furthermore, according to the invention, blow nozzles 23 are on the device attached, in the by the bending of the stack and the workpiece to be withdrawn Blow air in the resulting gap, thereby reliably separating the to be separated Workpiece is achieved from the stack. The blow nozzles 23 are expediently connected to the vacuum pump connected for the suction device 13, so that the compressed air is used.
