Abstract
Description
Die Erfindung betrifft einen Greifer für eine Flachmaterial verarbeitende Maschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a gripper for a flat material processing machine according to the generic term of claim 1.
In Flachmaterial, insbesondere Papier,
verarbeitenden Maschinen kommen häufig auf einem Träger befestigte
Greifer zum Einsatz, die dazu dienen, eine Kante eines Flachmaterialstücks zu klemmen
und so den Transport und gegebenenfalls die Verarbeitung des Flachmaterials
zu ermöglichen
(z. B.
Eine typische Anwendung ist z. B. ein Falzapparat, bei dem von einer bedruckten Bahn vereinzelte Druckerzeugnisse einem Falzmesserzylinder zugeführt werden, an dem Falzmesserzylinder von Greifern gehalten und zu einem Spalt zwischen dem Falzmesserzylinder und einem Falzklappenzylinder geführt werden, durch ein aus dem Falzmesserzylinder ausfahrendes Falzmesser entlang einer quer zur Förderrichtung verlaufenden Linie in eine Falzklappe des Falzklappenzylinders eingeschoben und dann von den Greifern des Falzmesserzylinders losgelassen werden, um ihre Weiterbeförderung in gefalztem Zustand auf dem Falzklappenzylinder zu ermöglichen.A typical application is e.g. B. a folder in which printed products separated from a printed web fed to a folding knife cylinder are held on the folding knife cylinder by grippers and become one Gap between the folding knife cylinder and a folding jaw cylinder are guided, by a folding knife extending out of the folding knife cylinder one across the conveying direction running line inserted into a jaw of the jaw cylinder and then let go of the jaws of the folding knife cylinder for their onward transportation to allow in the folded state on the jaw cylinder.
Die Greifer des Falzmesserzylinders sind im allgemeinen auf einer Greiferspindel montiert, die am Falzmesserzylinder in der Nähe von dessen Umfang montiert ist und schwenkbar ist, um ein Druckerzeugnis jeweils zum angemessenen Zeitpunkt einzuklemmen bzw. freizugeben. Eine solche Greiferspindel muss schnelle, abrupte Bewegungen zum Einklemmen bzw. Freigeben des Druckerzeugnisses durchführen.The grippers of the folding knife cylinder are generally mounted on a gripper spindle on the folding knife cylinder nearby is mounted from its circumference and can be swiveled around a printed product to pinch or release at the appropriate time. Such a gripper spindle must make rapid, abrupt movements Pinch or release the printed product.
Die Erfindung liegt die Aufgabe zurunde, einen Greifer für eine Flachmaterial verarbeitende Maschine zu schaffen, dessen Funktion und Verwendungsmöglichkeit verbessert ist.The invention is based on the object a gripper for to create a flat material processing machine whose function and possible use is improved.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the Features of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass der Greifer eine hohe Steifigkeit bei geringem Gewicht besitzt und daher schnellen, abrupten Schwenkbewegungen der Greiferspindel schnell folgen kann. Dieser Vorteil wird erreicht, indem die Steifigkeit des Greifers gegenüber der eines einfach aus Blech gestanzten Greifers ähnlicher Abmessungen durch eine Sicke erhöht ist, die sich entlang des Stiels des Greifers, zwischen einem Basisabschnitt desselben, der zur Befestigung an der Greiferspindel dient, und einem Kopfabschnitt zum Andrücken des Flachmaterials, insbesondere Papier, gegen einen Träger, erstreckt.The achievable with the invention The advantages are in particular that the gripper has a high Stiffness with low weight and therefore fast, abrupt Swivel movements of the gripper spindle can follow quickly. This Advantage is achieved by the rigidity of the gripper compared to the of a gripper of similar dimensions, simply punched out of sheet metal a bead increases which is along the handle of the gripper, between a base section the same, which is used for fastening to the gripper spindle, and a head section for pressing of the flat material, in particular paper, extends against a carrier.
Zur Erhöhung der Steifigkeit ist die Sicke vorzugsweise über den Basisabschnitt verlängert.To increase the stiffness is the Preferably bead over extended the base section.
Löcher zur Befestigung des Greifers an dem Träger sind im Basisabschnitt der Sicke gebildet. Dies erlaubt eine Befestigung des Greifers durch einfaches Anschrauben mit Hilfe von durch die Löcher verlaufenden Schrauben; eine Klemmung mit Hilfe von getrennt vom Greifer an der Spindel montierten Klemmhaltern ist nicht erforderlich.holes for fastening the gripper to the carrier are in the base section the bead formed. This allows the gripper to be fastened by easy to screw on using screws running through the holes; clamping with the help of separate from the gripper on the spindle assembled clamp holders is not required.
Vorzugsweise endet die Sicke vor einem gekrümmten Abschnitt des Kopfes. Die Steifigkeit dieses gekrümmten Abschnittes ist daher nicht so groß wie die des Stiels, so dass es möglich ist, eventuelle Abweichungen zwischen den Positionen der Spitzen der an der Spindel montierten Greifer durch eine Verformung des Kopfes auszugleichen.The bead preferably ends before a curved one Section of the head. The stiffness of this curved section is therefore not as big as that of the stem so that it is possible is, possible deviations between the positions of the tips of the the gripper mounted on the spindle by deforming the head compensate.
Um das Gewicht der Greifer und damit das Trägheitsmoment der Greiferspindel niedrig zu halten, sollte die Stärke des Blechs, aus dem die Greifer gebildet sind, nicht über 1,75 mm, vorzugsweise ca. 1,5 mm, betragen.The weight of the gripper and thus the moment of inertia to keep the gripper spindle low should be the strength of the Sheet from which the grippers are formed does not exceed 1.75 mm, preferably about 1.5 mm.
Um die Spitzen der Greifer exakt in einer Reihe ausrichten zu können und so zu gewährleisten, dass ein Stück Flachmaterial auf seiner gesamten Breite gleichzeitig von den Greifern erfasst wird, sind die Greifer vorzugsweise an einer abgeflachten Längsseite der Greiferspindel befestigt, welche die Orientierung der Greifer weitgehend vorgibt.Around the tips of the grippers exactly to be able to align in a row and so to ensure that one piece Flat material across its entire width simultaneously from the grippers is gripped, the grippers are preferably on a flattened long side attached to the gripper spindle, which determines the orientation of the gripper largely pretends.
