Description

Vorrichtung zum Vereinzeln des jeweils untersten Zuschnitts eines Stapels horizontal liegender Zuschnitte mit Hilfe eines Saugers Die Erfindung betrifft eine Vorrichtung zum Zuführen von Bogen, insbesondere gefalzte Bogen Papierblätter od. dgl. an Verarbeitungsmaschinen.Device for separating the bottom blank of a Stack of horizontally lying blanks with the aid of a suction device. The invention relates to a device for feeding sheets, in particular folded sheets of paper or the like on processing machines.

Bei einer bekannten Vorrichtung dieser Art werden die Bogen oder Blätter durch Saugdüsen erfaßt und an derselben Seite wird der Stapel durch Stützleisten angehoben, während der durch Saugdüsen erfaßte Bogen nach unten abgebogen wird. Das Herausnehmen und Ablegen des abgespaltenen Bogens erfolgt durch Greifer. In a known device of this type, the arc or Sheets are picked up by suction nozzles and on the same side the stack is supported by support strips raised while the sheet captured by suction nozzles is bent downwards. The split-off sheet is removed and deposited using grippers.

Solche Vorrichtungen haben den Nachteil, daß bei dem Herausziehen des vom Stapel abgespaltenen Bogens das Stapelgewicht zu einem großen Teil auf dem abgespaltenen Bogen liegt, so daß besonders bei gerillten Bogen eine einwandfreie Entnahme des abgespaltenen Bogens nur beschränkt möglich ist, und auch dann nur mittels verhältnismäßig teurer Greifer. Such devices have the disadvantage that when pulling out of the sheet split off from the stack, the stack weight to a large extent on the split sheet lies, so that especially with grooved sheets a flawless one Removal of the split-off sheet is only possible to a limited extent, and then only by means of relatively expensive grippers.

Die angegebenen Nachteile werden bei der Vorrichtung gemäß der Erfindung vermieden. Bei dem Herausziehen des abgespaltenen Bogens od. dgl. wird der Stapel an mehreren Seiten angehoben und dadurch eine reibungslose Entnahme des abgespaltenen Bogens ermöglicht. Durch diese Art der Bogenentnahme kann das Herausziehen des abgespaltenen Bogens mit dem gleichen Sauger erfolgen, der das Abspalten bewirkt. Hierdurch sind die Greifer überflüssig geworden. The indicated disadvantages are in the device according to the invention avoided. When the split-off sheet is pulled out or the like, the stack becomes raised on several sides and thereby a smooth removal of the split off Arch enables. This type of sheet removal can result in the extraction of the split-off Arc with the same sucker that causes the splitting off. Through this are the grippers have become superfluous.

Die Zeichnung stellt eine beispielsweise Ausführungsform des Erfindungsgegenstandes dar, und zwar in Fig. 1 und 2 je in Stirnansicht mit verschiedenen Arbeitsstellungen der einzelnen Teile. Der Bogenstapel 1 ruht auf einem Tisch 2. Der Trennstab 3 wird nach dem Abspalten des Bogens durch den Sauger 4 so in Richtung Stapelmitte bewegt, daß hierdurch ein Anheben des Stapels erfolgt (Fi g. 2). The drawing represents an example embodiment of the subject matter of the invention represents, namely in Fig. 1 and 2 each in front view with different working positions of the individual parts. The stack of sheets 1 rests on a table 2. The separating rod 3 is after splitting off the sheet moved by the suction device 4 in the direction of the center of the stack, that this results in a lifting of the stack (Fi g. 2).

Durch den Nocken 5, der drehbar gelagert ist, findet gleichzeitig ein Anheben des Stapels 1 an der gegenüberliegenden Seite statt (Fig. 2). Der abgespaltene Bogen kann nun von dem Sauger 4 aus der Stapelhalterung 6 reibungsfrei herausgezogen werden.By the cam 5, which is rotatably mounted, takes place at the same time a lifting of the stack 1 on the opposite side takes place (FIG. 2). The split off The sheet can now be pulled out of the stack holder 6 by the sucker 4 without friction will.

Patentanspruch: Vorrichtung zum Vereinzeln des jeweils untersten Zuschnittes eines Stapels horizontal liegender Zuschnitte mit Hilfe eines Saugers, der ein Ende des zu vereinzelnden Zuschnitts abkippt und mit Mitteln zum Anheben des Stapelendes, welches über dem abgekippten Zuschnittsende liegt, dadurchgekennzeichnet, daß die Stapelhebelmittel von mehreren Seiten am Stapel angreifen und ihn jeweils vollständig vom vereinzelten Zuschnitt abheben. Claim: Device for separating the lowest Cutting a stack of horizontally lying blanks with the help of a suction device, which tilts one end of the blank to be separated and has means for lifting of the end of the stack, which lies above the tilted blank end, characterized in that that the stack lever means attack from several sides on the stack and him each stand out completely from the individual blank.
