Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, die sich durch die Merkmale gemäß Kennzeichen des Patentanspruches 1 auszeichnet Die Erfindung ist anhand von Ausführungsbeispielen in den Zeichnungen dargestellt. Dabei zeigt F i g. 1 das hintere Kettenrad der Kettengreiferauslage in der Seitenansicht mit der erfindungsgemäßen Vorrichtung zur Druckbogenentnahme, F i g. 2 die Draufsicht des hinteren Bereiches der Kettengreiferauslage gemäß F i g. 1, F i g. 3 die Vorrichtung gemäß Fig. 1, jedoch in der für die Druckbogenentnahme eingestellten Position und F i g. 4 eine weitere Ausführungsform mit modifizierter Betätigung des Sperrmechanismus. According to the invention, this object is achieved by a device which is characterized by the features according to the characterizing part of claim 1 The invention is illustrated in the drawings using exemplary embodiments. F i g. 1 the rear sprocket of the chain gripper delivery in a side view with the device according to the invention for removing printed sheets, FIG. 2 the top view of the rear area of the chain gripper delivery according to FIG. 1, F. i g. 3 shows the device according to FIG. 1, but in the one set for the printing sheet removal Position and F i g. 4 shows a further embodiment with modified actuation the locking mechanism.
Die F i g. 1 und 2 zeigen den hinteren Teil des Aufbaues des Bogenauslegers. In den Seitenwänden 1, 2 sind auf der Welle 3 die hinteren Kettenräder 4, 5 drehfest gelagert, auf denen die Greiferketten 6, 9 ablaufen, die in entsprechenden Abständen mit Greiferreihen 7 versehen sind, welche den Papierbogen 8 dem Stapel 45 zuführen. The F i g. 1 and 2 show the rear part of the structure of the bow boom. In the side walls 1, 2, the rear sprockets 4, 5 are rotatably fixed on the shaft 3 stored on which the gripper chains 6, 9 run, which at appropriate intervals are provided with rows of grippers 7, which feed the sheet of paper 8 to the stack 45.
Ebenfalls auf der Welle sind axial verschiebbar, aber drehfest, zwei Stützscheiben 10, 11 gelagert, welche die Bogenführung, insbesondere bei der Druckbogenentnahme gemäß F i g. 3, unterstützen. Vordere Bogenanschläge 12 sorgen weiterhin für eine saubere Stapelbildung. Also on the shaft are axially displaceable, but non-rotatable, two Support disks 10, 11 mounted, which guide the sheet, especially when removing the printed sheet according to FIG. 3, support. Front bow stops 12 continue to provide a neat stacking.
An einer der Seitenwände 2 ist am Anlenkpunkt 13 ein Schwenkhebel 14 drehbar gelagert. Dieser Schwenkhebel 14 trägt, durch zwei Halteschrauben 15 gehalten, einen Kurvenhebel 16, der mit der Greiferöffnungskurve 17 ausgestattet ist, an der die Kurvenrolle 18 der Greiferreihe 7 bei der Bogenauslage zur Stapelbildung abrollt und so die Greiferöffnung bewirkt. Im vorderen Bereich des Kurvenhebels 16 ist weiterhin eine Kurvenrolle 19 daran drehbar gelagert, die allerdings bei der stapelbildenden Bogenauslage keine Funktion hat Eine am Kurvenhebel 16 angreifende und sich an einer an der Seitenwand 2 befestigte Halterung 20 abstützende Druckfeder 21 drückt den Schwenkhebel 14 mit dem daran angebrachten Kurvenhebel 16 gegen eine Sperrklinke 22. Die an dem, aus dem Ausleger herausragenden Ende mit einem Handgriff 23 versehene Sperrklinke 22 ist durch einen, an der Seitenwand 2 befestigten Lagerbock 24 gehalten und geführt, und wird weiterhin durch die Druckfeder 25 in der, in F i g. 1 dargestellten Position gehalten. On one of the side walls 2, a pivot lever is at the articulation point 13 14 rotatably mounted. This pivot lever 14 is supported by two retaining screws 15 held, a cam lever 16, which is equipped with the gripper opening cam 17 is on which the cam roller 18 of the gripper row 7 in the sheet delivery for stacking unrolls and thus causes the gripper to open. In the front area of the cam lever 16 is also a cam roller 19 rotatably mounted thereon, which, however, at the stack-forming sheet delivery has no function and a compression spring supported on a bracket 20 attached to the side wall 2 21 presses the pivot lever 14 with the cam lever 16 attached to it against a Locking pawl 22. The end protruding from the boom with a handle 23 provided pawl 22 is through a bearing block attached to the side wall 2 24 held and guided, and is continued by the compression spring 25 in the, in F i g. 1 held position shown.
Fig.3 schließlich, zeigt die Druckbogenentnahme-Einrichtung in der dafür eingestellten Position, Zu diesem Zweck wird manuell die Sperrklinke 22 entgegen der Federkraft der Druckfeder 25 nach hinten gezogen, so daß sich der Kurvenhebel 16 bzw. die daran angebrachte Kurvenrolle 19 unter Einwirkung der Druckfeder 21 an die, mit der Welle 3 drehfest verbundene Steuerkurve 26 anlegen kann. Die Phasenlage der Steuerkurve 26 ist dabei so gewählt, daß beim Passieren der Greiferreihe 7 deren Kurvenrolle 18 mit der Greiferöffnungskurve 17 nicht in Kontakt gerät, und somit ein Freigeben des Bogens 8 unterbleibt Dieser wird daher weitertransportiert, bis die Kurvenrolle 18 mit einer stationär angebrachten weiteren Greiferöffnungskurve 27 in Berührung kommt Die dann eingeleitete Öffnung der Greiferreihe 7 gibt den Bogen frei, der nun in einen, am hinteren Ende des Auslegers angebrachten Führungskanal 28 einläuft und von dort nach außen geführt wird. Finally, FIG. 3 shows the printing sheet removal device in FIG position set for this purpose, for this purpose the pawl 22 is manually opposed the spring force of the compression spring 25 is pulled backwards, so that the cam lever 16 or the cam roller 19 attached to it under the action of the compression spring 21 can apply to the control cam 26, which is connected non-rotatably to the shaft 3. The phase position the control cam 26 is chosen so that when passing the row 7 of grippers Cam roller 18 does not come into contact with the gripper opening curve 17, and thus the sheet 8 is not released. It is therefore transported on until the cam roller 18 with a stationary attached further gripper opening curve 27 comes into contact The then initiated opening of the row of grippers 7 is the Arch free, which is now in a guide channel attached to the rear end of the boom 28 enters and is led from there to the outside.
Durch Andrückfedern 29 federnd gelagerte und an den Stützscheiben 10, 11 sich abstützende Transportrollen 30 wird die Weiterleitung des auszugebenden Papierbogens 8 sichergestellt.Resiliently mounted by pressure springs 29 and on the support disks 10, 11 supporting transport rollers 30 are the forwarding of the output Sheet of paper 8 ensured.
F i g. 4 zeigt eine der vorbeschriebenen Ausführungsform ähnliche Ausgestaltung der erfindungsgemäßen Vorrichtung. Der wesentliche Unterschied ist dabei, daß Einleitung und Durchführung der Druckbogenentnahme nicht manuell, sondern elektromechanisch erfolgt. F i g. 4 shows an embodiment similar to the above-described embodiment Design of the device according to the invention. The main difference is while that initiation and implementation of the printing sheet removal not manually, but takes place electromechanically.
Dabei wird der Sperrklinke 31 bzw. dessen Position durch einen, an seinem unteren Anlenkpunkt 32 angreifenden Magnetschalter 33 bestimmt. Während der sta- pelbildenden Bogenauslage ist die Sperrklinke 31 bei nicht aktiviertem Magnetschalter 33 aufgrund der Federkraft der Druckfeder 48 gegen den Kurvenhebel 16 geschwenkt und fixiert diesen, so daß die an ihm angebrachte Greiferöffnungskurve 17 wirksam werden kann. The pawl 31 or its position is thereby activated by a its lower pivot point 32 attacking magnetic switch 33 is determined. During the sta- pel-forming sheet delivery is the pawl 31 when the magnetic switch is not activated 33 pivoted against the cam lever 16 due to the spring force of the compression spring 48 and fixes it so that the gripper opening curve 17 attached to it becomes effective can be.
Für die Betätigung des Magnetschalters 33 ist ein Wählschalter 34 vorgesehen, über den, durch entsprechende elektrische Steuerelemente einfach durchführbar, eine Einzelbogenentnahme oder über z. B. Zeitrelais bzw. Zählschalter auch eine zahlenmäßig vorgebbare Mehrbogenentnahme eingeleitet werden kann. Eine Zähleinheit 35 kann zu diesem Zweck mit einer Tastrolle 36 die Steuerkurve 26 abtasten und somit deren Umdrehungen bzw. die ausgegebenen Druckbogen 8 zählen. Ein in beiden Ausführungsformen auf der Steuerkurve 26 vorgesehener kleiner Überhub 46 ermöglicht jeweils das Einrasten der Sperrklinke 22,31 in die Grundstellung zum entsprechenden Zeitpunkt. A selector switch 34 is used to operate the magnetic switch 33 provided, via which, by means of appropriate electrical control elements, can be easily carried out, a single sheet removal or via z. B. timing relay or counter switch also one numerically predeterminable multiple sheet removal can be initiated. A counting unit For this purpose 35 can scan the control cam 26 with a feeler roller 36 and thus their revolutions or the printed sheets 8 output count. One in both embodiments The small overstroke 46 provided on the control cam 26 enables each to engage the pawl 22,31 in the basic position at the corresponding point in time.
