Abstract
Die Erfindung betrifft eine Einrichtung zum Vereinzeln und Zuführen von Bogen mit Trennsaugern zum Erfassen des jeweils obersten Bogens eines Bogenstapels in seinem in Bogentransportrichtung hinteren Bereich und Übergeben an den Bogen in Bogentransportrichtung zu einer Fördereinrichtung transportierende Transportsauger. DOLLAR A Aufgabe der Erfindung ist es, eine Einrichtung zu schaffen, mit der eine Schrägbogenkorrektur auch bei großformatigen Bogen ohne Beeinträchtigung der Produktivität möglich ist. DOLLAR A Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Fördereinrichtung aus einer umlaufenden Transportwalze und mit dieser periodisch in Wirkverbindung gelangenden Taktrollen besteht, dadurch gekennzeichnet, dass die Taktrollen (16) unabhängig voneinander an die Transportwalze (15) anstellbar sind und der Anstellzeitpunkt der Taktrollen (16) unterschiedlich voneinander einstellbar ist.The invention relates to a device for separating and feeding sheets with separating suction devices for grasping the uppermost sheet of a sheet stack in its rear region in the sheet transport direction and transferring it to the sheet in the sheet transport direction to a conveying device transporting suction device. DOLLAR A object of the invention is to provide a device with which an inclined sheet correction is possible even with large format sheets without impairing productivity. DOLLAR A According to the invention, the object is achieved in that the conveying device consists of a rotating transport roller and clock rollers which periodically come into operative connection with it, characterized in that the clock rollers (16) can be set independently of one another on the transport roller (15) and the point in time at which the clock rollers start (16) can be set differently from one another.
Description
Die Erfindung betrifft eine Einrichtung zum Vereinzeln und Zuführen von Bogen mit Trennsaugern zum Erfassen des jeweils obersten Bogens eines Bogenstapels in seinem in Bogentransportrichtung hinteren Bereich und Übergeben an den Bogen in Bogentransportrichtung zu einer Fördereinrichtung transportierende Transportsauger, wobei die Fördereinrichtung aus einer umlaufenden Transportwalze und mit dieser periodisch in Wirkverbindung gelangenden Taktrollen besteht.The invention relates to a device for separating and feeding of sheets with suction cups for grasping the top sheet of a sheet stack in its rear in the sheet transport direction Area and surrender on the sheet in the sheet transport direction to a conveyor Transport vacuum, the conveyor from a rotating transport roller and periodically with it There is an active connection between the clock roles.
Bei derartigen Einrichtungen wird der jeweils oberste Bogen eines Bogenstapels zum Vereinzeln von den eine Hubbewegung ausführenden Trennsaugern im Bereich der Bogenhinterkante erfasst und angehoben. Durch Unterblasen wird der oberste Bogen über die gesamte Fläche vom Folgebogen getrennt und so vereinzelt. Der vereinzelte Bogen wird an eine in und entgegen der Bogentransportrichtung gerichtete Bewegung ausführende Transportsauger übergeben, die den Bogen in Bogentransportrichtung zur Fördereinrichtung transportieren. Gelangt der Bogen mit seiner Vorderkante in den Bereich der Fördereinrichtung, werden die Taktrollen gegen die Transportwalze gesteuert und so der Bogen von der Wirkpaarung Taktrollen/Transportwalze erfasst. Nach dem Freigeben des Bogens von den Transportsaugern wird der zwischen der Transportwalze und den Taktrollen geklemmte Bogen auf einen Bändertisch gefördert, durch diesen gegen in die Bahn des Bogens schwenkbare Vordermarken geführt und so nach der Vorderkante ausgerichtet. Die an den Vordermarken angelegten Bogen werden bezüglich der Lage der Vorderkante von einer Abtasteinrichtung erfasst.With such facilities the top sheet of a sheet stack for separating the separating suction cups carrying out a lifting movement detected and raised in the area of the trailing edge of the sheet. By blowing in the top arc is over the entire area separated from the following sheet and so isolated. The isolated bow is directed at one in and against the sheet transport direction Movement executing Hand over vacuum cleaner, that transport the sheet in the sheet transport direction to the conveyor. reaches the sheet with its front edge in the area of the conveyor, the clock rollers are controlled against the transport roller and so the arc is captured by the active pairing of timing rollers / transport roller. After releasing the sheet from the transport suction cups, the between the transport roller and the timing rollers a conveyor table encouraged through this front stamps which can be pivoted into the path of the sheet guided and so aligned to the leading edge. The on the front brands created sheets are regarding the position of the front edge detected by a scanner.
Wird durch die Abtasteinrichtung
eine tendenzielle Schräglage
der einlaufenden Bogen erfasst, ist es bekannt, die Transportsauger
oder die Trennsauger entsprechend der Schräglage der Bogen um eine lotrechte
Achse geringfügig
zu verdrehen und damit die Bogen rechtwinklig zur Bogentransportrichtung
auszurichten (
Da der Drehpunkt der Transportsauger oder der Trennsauger aber im Bereich der Bogenhinterkante liegt, kommt es insbesondere bei großformatigen Bogen dazu, dass bei einer geringfügigen Schrägbogenkorrektur bereits im Bereich der Bogenvorderkante ein solcher seitlicher Versatz auftritt, dass eine exakte Ausrichtung nach der Seitenkante nicht mehr realisierbar ist, was zu Fehlanlagen und damit zur Minderung der Produktivität der Gesamtmaschine führt.Because the pivot point of the vacuum cleaner or the separating suction cup is in the area of the trailing edge of the sheet, it occurs especially in large format Sheet that with a slight inclined sheet correction already in In the area of the leading edge of the sheet such a lateral offset occurs that exact alignment to the side edge is no longer possible is what leads to faulty systems and thus a reduction in the productivity of the overall machine leads.
Aufgabe der Erfindung ist es, eine Einrichtung zu schaffen, mit der eine Schrägbogenkorrektur auch bei großformatigen Bogen ohne Beeinträchtigung der Produktivität möglich ist.The object of the invention is a To create facility with which an inclined sheet correction even with large format Bow without impairment of productivity possible is.
Erfindungsgemäß wird die Aufgabe durch eine Einrichtung nach dem Anspruch 1 gelöst.According to the invention, the object is achieved by a Device according to claim 1 solved.
Die erfindungsgemäße Einrichtung gestattet es, mit einfachen Mitteln auch bei großformatigen Bogen eine Schrägbogenkorrektur zu realisieren, ohne die Produktivität der Anlage nachteilig zu beeinflussen.The device according to the invention allows With simple means, even with large-format sheets, an inclined sheet correction to realize without adversely affecting the productivity of the system influence.
Die Erfindung wird an einem Ausführungsbeispiel näher erläutert. In den zugehörigen Zeichnungen zeigen:The invention is based on an embodiment explained in more detail. In the associated The drawings show:
