Description

Vorrichtung zur Entnahme von Einzelblättern oder -bogen aus einem Stapel mit Hilfe eines gesteuert kippbaren Saugarms Die Erfindung geht von solchen Vorrichtungen zur Entnahme von Einzelblättern oder -bogen aus einem Stapel aus, bei denen ein unter das jeweils unterste Blatt greifender, mit einem umlaufenden Abzugsegment zusammenarbeitender Saugarm mit einer zum ihre Längsachse hin- und herschwingenden, an eine Sangquelle angeschlossenen Hohlwelle radial verbunden und mit einem kippbar gelagerten, durch die Schwingbewegung gesteuerten Saugkopf versehen ist. Device for removing single sheets or sheets from one Stack with the help of a controlled tiltable suction arm. The invention is based on such Devices for removing single sheets or sheets from a stack, in which one reaches under the bottom sheet, with a circumferential one Suction arm working together with the extraction segment with a back and forth to its longitudinal axis oscillating hollow shaft connected to a sound source and radially connected Equipped with a tiltable suction head controlled by the oscillating movement is.

Die Erfindung bezweckt, durch besondere Anordnung und Ausbildung der Kippsteuerung des Sangkopfes gegenüber bekannten Ausführungsformen eine vereinfachte raumsparende Bauweise ohne Beeinträchtigung der betrieblichen Zuverlässigkeit zu erzielen. The invention aims through a special arrangement and training the tilt control of the Sangkopf compared to known embodiments a simplified space-saving design without impairing operational reliability achieve.

Zu diesem Zweck kommt es bei der Erfindung darauf an, daß die I(ippsteuerung aus einem durch eine Kurve längsverschiebbar gehaltenen gefederten Gestänge besteht, das durch eine Muffe der an die Saugquelle angeschlossenen, um ihre Längsachse hin- und herschwingenden Hohlwelle hindurchgeführt und mit dem Saugkopf unterhalb seiner Kipplagerung durch ein Gelenk verbunden ist. For this purpose it is important in the invention that the I (ipp control consists of a spring-loaded linkage held longitudinally displaceable by a curve, which is connected to the suction source by a sleeve around its longitudinal axis. and passed through swinging hollow shaft and with the suction head below it Tilting bearing is connected by a joint.

Durch diese vereinfachte, ausschließlich auf die Vermeidung von Leerluftspalten zwischen dem jeweils untersten Stapelblatt und damit auf ein gleichmäßiges Anlegen des Blattes an die Saugfläche abzielende Ausbildung der Kippsteuerung des Saugkopfes unterscheidet sich die Entnahmevorrichtung nach der Eriindung grundsätzlich von bekannten Bogenentnehmern, bei denen durch einen an einem Schwenkhebel angelenkten und kippbar gesteuerten Saugarm von einem heb- und senkbaren Stapeltisch das jeweils oberste Stapelblatt abgehoben und zugleich durch die Schwenkbewegung dieses Hebelsystems nach Maßgabe der Verminderung der Stapelhöhe der Hubantrieb des Stapel tisches mittels einer Klinkschaltung ausgelöst wird. This simplified, exclusively to the avoidance of empty air gaps between the bottom stack sheet in each case and thus to ensure that it is laid out evenly of the sheet aimed at the suction surface formation of the tilt control of the suction head the removal device differs fundamentally from according to the invention known sheet extractors, in which articulated by one on a pivot lever and tiltable controlled suction arm from a liftable and lowerable stacking table The top stack sheet is lifted off and at the same time by the pivoting movement of this lever system in accordance with the reduction in the stack height of the lifting drive of the stacking table by means of a latch circuit is triggered.

Wie die Erfindung im einzelnen ausgeführt sein kann, ergibt sich aus der Beschreibung eines in der Zeichnung schematisch dargestellten Beispiels. How the invention can be carried out in detail emerges from the description of an example shown schematically in the drawing.

Fig. 1 bis 5 zeigen die verschiedenen Stellungen des kippbaren Saugkopfes vom Beginn bis zur Beendigung der Blattentnahme. 1 to 5 show the different positions of the tiltable suction head from the beginning to the end of the leaf removal.

Mit 1 ist die an eine Saugquelle angeschlossene Hohlwelle bezeichnet, die um ihre Längsachse hin- und herschwingt. Auf dieser Welle ist eine Muffe 2 befestigt, die einen bis unter den Blatt- oder Bogenstapel 3 reichenden Arm 4 trägt. Am vorderen Ende dieses A rmes ist der Saugkopf 5 mittels des Stiftes 6 kippbar gelagert. Zur Verbindung des Saugkopfes 5 mit der Hohlwelle 1 dient ein Schlauch 7. The hollow shaft connected to a suction source is denoted by 1, which swings back and forth around its longitudinal axis. A sleeve 2 is attached to this shaft, which carries an arm 4 reaching below the stack of sheets or sheets 3. At the front At the end of this arm, the suction head 5 is mounted tiltably by means of the pin 6. To the A hose 7 is used to connect the suction head 5 to the hollow shaft 1.

Die Kippbewegung des Saugkopfes 5 wird durch eine Kurve 8 und ein durch die schwingende Muffe 2 hindurchtretendes Gestänge 9 gesteuert. Das Gestänge 9 ist an einem Ende mit einer an dem Kurvenhebel 8 an- liegenden RollelO und am anderen Ende bei 11 am Saugkopf 5 angelenkt. Zwischen dem die Rolle 10 tragenden Ende des Gestänges 9 und der Muffe 2 ist eine Feder 12 angeordnet. The tilting movement of the suction head 5 is indicated by a curve 8 and a through the oscillating sleeve 2 passing linkage 9 controlled. The linkage 9 is at one end with a on the cam lever 8 lying RollelO and on the other Articulated at 11 on the suction head 5 at the end. Between the end of the bearing the roller 10 Linkage 9 and the sleeve 2, a spring 12 is arranged.

Wenn der Arm 4 aus der in Fig. 1 dargestellten Lage in die Stellung nach Fig. 2 nach abwärts zu schwingen beginnt, wird der Saugkopf 5, der den untersten Bogen 13 des Stapels 3 angesaugt hält, durch das Steuergestänge 9 so gekippt, daß er mit seiner ganzen oberen Fläche mit dem Blatt 13 in Berührung bleibt. Diese Beziehung bleibt erhalten, bis die Stellung nach Fig. 3 erreicht ist, bei der der Abzug des aus dem Stapel von unten her abgesaugten Blattes oder Bogens 13 beginnt, der anschließend über die Stellungen nach Fig. 4 und 5 beendet wird. When the arm 4 from the position shown in Fig. 1 in the position 2 begins to swing downwards, the suction head 5, which is the lowest Arch 13 of the stack 3 is sucked in, tilted by the control linkage 9 so that it remains in contact with the sheet 13 with its entire upper surface. This relationship remains until the position of FIG. 3 is reached, in which the deduction of the from the stack from below sucked sheet or sheet 13 begins, which then via the positions of FIGS. 4 and 5 is ended.

Die obere Fläche des Saugkopfes 5 besteht vorteilhaft aus einer auswechselbaren, mit Sauglöchern und Hohlkehlen versehenen Platte, die den jeweils zu verarbeitenden Blattgrößen und Papierarten angepaßt ist. The upper surface of the suction head 5 advantageously consists of an exchangeable, with suction holes and flutes provided with the respective to be processed Sheet sizes and types of paper is adapted.

Durch die Kurvenform des Schwinghebels 8 läßt sich die günstigste Stellung des Saugkopfes 5 zum angesaugten Blatt 13 bestimmen. The curve shape of the rocker arm 8 can be the cheapest Determine the position of the suction head 5 in relation to the sucked sheet 13.
