A stop (8) holds the printed sheet at the end of its circular travel path around the conveyor drum. The stop is arranged to follow a guide lever (1) which produces a guide gap (10). An opening mechanism opens the guide gap downstream of the stop.

Description

Die Erfindung betrifft eine Vorrichtung zur Beschickung der Sammelstrecke eines Sammelhefters nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for loading the collecting section of a saddle stitcher according to the preamble of claim 1.

Vorrichtungen der eingangs genannten Art, auch Anleger bezeichnet, sind die Achillessehne bei der Beschickung der Sammelstrecke eines Sammelhefters mit Druckbogen von unterschiedlicher Papierqualität und Dicke.Devices of the type mentioned at the beginning, also called feeders, are the Achilles tendon when loading the collecting section of a saddle stitcher with printed sheets of different paper quality and thickness.

Insbesondere die Druckbogenführung vor dem Anschlag für den Falz eines von einem Stapel abgezogenen Druckbogens führt oft zu Anlegefehlern, die am Ende des Sammel- oder des Heftvorganges ein Ausschleusen eines fehlerhaften Druckproduktes zur Folge haben.In particular, the printing sheet guide before the stop for the fold of a printing sheet pulled from a stack often leads to misfeeds which result in a defective printed product being discharged at the end of the collecting or stapling process.

Dieser Mangel ist in vielen Fällen auf eine unpräzise Einstellung der Druckbogenführung oder der Führungsanordnung vor dem Anschlag, wo der Druckbogen einem Aufprall- und Stauchungseffekt ausgesetzt ist, zurückzuführen. Dabei tendiert der Druckbogen wenigstens partiell zum Abfheben von der Fördertrommel und erfährt so eine Lage im Führungsspalt, dass er von der anschliessend auf die gegenüberliegenden Kanten der offenen Seiten einwirkenden Öffnungsvorrichtung nicht in jedem Fall in der richtigen Lage erfasst werden kann.
Durch eine genauere Anpassung des Führungsspaltes an die verschiedenen Druckbogen könnte die Produktionszuverlässigkeit verbessert werden.In many cases, this deficiency is due to an imprecise adjustment of the printed sheet guide or the guide arrangement before the stop, where the printed sheet is exposed to an impact and compression effect. The tends to The printed sheet is at least partially lifted off the conveyor drum and experiences a position in the guide gap such that it cannot always be detected in the correct position by the opening device which then acts on the opposite edges of the open sides.
The production reliability could be improved by more precisely adapting the guide gap to the different printed sheets.

Aufgabe der Erfindung ist es nun, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, mit der die Zuverlässigkeit hinsichtlich Verarbeitungsqualität verbessert und die Produktionszeit verkürzt werden kann.The object of the invention is now to provide a device of the type described in the introduction with which the reliability with regard to processing quality can be improved and the production time can be shortened.

Erfindungsgemäss wird diese Aufgabe nach dem Kennzeichen von Patentanspruch 1 gelöst, wobei durch die Lage der Führungsanordnung an der Fördertrommel, oberhalb der durch die Drehachse letzterer verlaufenden Horizontalebene, eine die gleitende Wirkung im Führungsspalt begünstigende Situation genutzt werden kann, insbesondere deshalb, weil die statisch wirkende Gravitation an der Führungsanordnung beträchtlich reduziert werden kann.
Die dadurch entstehenden günstigen Reibungsverhältnisse bewirken gleichzeitig eine schonende Behandlung der Druckbogen.According to the invention, this object is achieved according to the characterizing part of patent claim 1, whereby the situation of the guide arrangement on the conveyor drum, above the horizontal plane running through the axis of rotation of the latter, can be used to promote the sliding effect in the guide gap, in particular because the statically acting one Gravity on the guide assembly can be reduced considerably.
The resulting favorable friction conditions also result in a gentle treatment of the printed sheets.

Das Verstellen der Führungsanordnung erfolgt vorteilhaft gegen eine Kraft, die durch die Gravitation und/oder eine Feder erzeugt wird.The adjustment of the guide arrangement advantageously takes place against a force which is generated by gravitation and / or a spring.

Vorzugsweise soll auch diese Kraft verstellbar ausgebildet sein.This force should preferably also be adjustable.

Die der Anschlagvorrichtung vorgeschaltete, etwa senkrecht zur Flugbahn der Druckbogen bzw. der Fördertrommel in dem Führungsspalt bewegbare Führungsrolle und ein an letztere anschliessendes, von der Führungsrolle unabhängig betätigbares Leitorgan bilden die Führungsanordnung, wobei die drehbare Führungsrolle zweckmässig an einem mit der Unterkante die Zutrittsöffnung zu dem Anschlag bildenden Support gelagert ist, sodass der am Anschlag auftreffende Druckbogen von seiner Position nicht abweicht bzw. dass die Druckbogen bezüglich der nachgeschalteten Öffnungsvorrichtung eine konstante Erfassungslage einnehmen.The one upstream of the stop device, approximately perpendicular to the trajectory of the printed sheets or the conveying drum in the guide gap Movable guide roller and a guide element adjoining the latter, which can be actuated independently of the guide roller, form the guide arrangement, the rotatable guide roller being expediently mounted on a support which forms the access opening to the stop with the lower edge, so that the printed sheet striking the stop does not deviate from its position or does not that the printed sheets are in a constant detection position with respect to the downstream opening device.

Als Support eignet sich insbesondere ein Hebel, an dessen freiem Ende die Führungsrolle gelagert ist, wobei anstelle einer Schwenkachse für den Hebel der Support zum gleichen Zweck in einer Führung bewegt werden könnte.A support is particularly suitable as a lever, on the free end of which the guide roller is mounted, wherein instead of a pivot axis for the lever, the support could be moved in a guide for the same purpose.

Der einfachheithalber ist der Support bzw. der Hebel an der Anschlagvorrichtung befestigt.For the sake of simplicity, the support or the lever is attached to the stop device.

Zur Verstellung des Führungsspaltes vor dem Anschlag aufgrund des abweichenden Verhaltens der verschiedenen Druckbogen beim Aufprall am Anschlag ist es vorteilhaft, die Führungsrolle zwischen ihr und dem Anschlag gegenüber der der Fördertrommel zugewendeten Unterkante des Supports bzw. Hebels verstellbar auszubilden.To adjust the guide gap before the stop due to the different behavior of the different printed sheets in the event of an impact on the stop, it is advantageous to make the guide roller adjustable between it and the stop relative to the lower edge of the support or lever facing the conveyor drum.

Zur Begrenzung der maximalen Führungsspaltweite am Anschlag ist dem Support bzw. Hebel ein Endanschlag zugeordnet.To limit the maximum guide gap at the stop, an end stop is assigned to the support or lever.

Das Leitorgan ist vorteilhaft mit einer Führungsvorrichtung verbunden und etwa radial zur Drehachse der Fördertrommel von letzterer abhebbar geführt, sodass im Führungsspalt an den betroffenen Druckbogenoberflächen annähernd gleichmässige Reibungsverhältnisse eintreten.The guide member is advantageously connected to a guide device and is guided such that it can be lifted off from the latter, approximately radially to the axis of rotation of the conveyor drum, so that approximately uniform friction conditions occur in the guide gap on the printing sheet surfaces concerned.

Zu diesem Zweck ist die Führungsvorrichtung vorzugsweise mit einer Rollenführung ausgebildet, die einen relativ günstigen Reibungskoeffizienten aufweist.For this purpose, the guide device is preferably designed with a roller guide which has a relatively favorable coefficient of friction.

Im Sinne einer schonenden Druckbogenbehandlung schliesst die Bewegungsrichtung der Führungsanordnung oder des Leitorgans resp. die mit letzteren verbundene Führungsvorrichtung mit einer durch die Drehachse der Fördertrommel gelegten Horizontalebene einen Winkel von weniger als 45° ein.In the sense of a gentle treatment of printed sheets, the direction of movement of the guide arrangement or the guide member closes. the guide device connected to the latter makes an angle of less than 45 ° with a horizontal plane through the axis of rotation of the conveyor drum.

Nachfolgend ist die erfindungsgemässe Einrichtung unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erläuterten Einzelheiten verwiesen wird, erörtert. Es zeigt die

einzige Figur
eine erfindungsgemässe Führungsanordnung für Druckogen in einem auszugsweise dargestellten Anleger.
The device according to the invention is discussed below with reference to the drawing, to which reference is made with regard to all details not explained in detail in the description. It shows the
only figure
a guide arrangement according to the invention for Druckogen in a feeder shown in excerpts.

Die einzige Figur zeigt eine Führungsanordnung 1 an der Fördertrommel 2 eines Druckbogenanlegers 3 für einen Sammelhefter (nicht dargestellt), wie er beispielsweise in den Schweizer Pa-tentschriften 586 611, 617 905 und 652 103 offenbart ist. Dieser Anleger 3 dient der Beschickung einer Sammelstrecke eines Sammelhefters und besteht aus einer die Druckbogen falzvoran von einem Stapel 5 eines benachbarten Bogenmagazins 6, von dem der Tisch 7 in der Figur gezeigt ist, abziehenden, rotierenden Fördertrommel 2, welcher eine die einzelnen Druckbogen 4 teilweise von der Stapelunterseite abhebende Saugvorrichtung und eine die abgehobenen Druckbogenteile erfassende Greifvorrichtung (beide nicht dargestellt) zugeordnet sind, und einer an der Umlaufbahn der Druckbogen 4 angeordneten, letztere an dem Falz aufhaltende Anschlagvorrichtung 8, welche mit einer vorgeschalteten Führungsanordnung 9 zusammenwirkt, die mit der Fördertrommel 2 einen Führungsspalt 10 bildet. Diese Führungsanordnung 1 wirkt auch auf die Druckbogen 4 ein, wenn diese von der Öffnungsvorrichtung (nicht gezeichnet) erfasst und entgegengesetzt an die Sammelstrecke weitertransportiert werden.
Die dem Anschlag bzw. der Anschlagvorrichtung 8 zugeführten Druckbogen 4 heben die Führungsanordnung 9 von der Fördertrommel 2 ab, wobei dies gegen eine aus der Gravitation gebildeten Kraft an der Führungsanordnung 9 und/oder gegen eine Federkraft erfolgt. Der stationären Anschlagvorrichtung 8 ist eine Führungsrolle 10 vorgeschaltet, die an einem Hebel 12 frei drehbar gelagert ist und durch den Druckbogen 4 im Führungsspalt 10 in Drehung versetzt wird. In der Ruhestellung steht die Führungsrolle 11 durch eine auf den Hebel 12 einwirkende Druckfeder 13 an der Fördertrommel 2 an.
Die Anschlagvorrichtung 8 besitzt eine zum Anschlag führende Zutrittsöffnung 14, die einerseits durch eine von unten gekrümmt an eine mit der Fördertrommel 2 fluchtende untere Führungsfläche und andererseits durch die Unterkante des Hebels 12 verstellbar ausgebildet ist. Der Anschlag selbst ist durch ein den Aufprall der Druckbogen 4 dämpfendes Anschlagelement 15 aus Gummi oder einer Gummilegierung konstruiert. Zur Begrenzung der Zutrittsöffnung 14 ist eine Ausnehmung 16 am Hebel 12 mit einem Nocken 17 versehen, welcher einem Endanschlag 18 an der Anschlagvorrichtung 8 zugeordnet ist.
Weiterhin besitzt die Führungsanordnung 1 ein Leitorgan 19, das mit Ausnahme des von dem Anschlag abgewendeten Endabschnitt 20 auf der Länge des Führungsspaltes 10 etwa parallel zu dem Umfang der Fördertrommel 2 verläuft.
Die Unterkante des Hebels 12 bildet zwischen dem Anschlag und der Führungsrolle 11 einen Abschnitt des Führungsspaltes 10, wobei die Führungsrolle 11 zur Verstellung der Durchtrittsweite des erwähnten Abschnittes verstellbar, bspw. durch eine exzentrisch verdrehbare Welle, an dem Hebel 12 gelagert ist. Das Leitorgan 19 wiederum ist mit einer Führungsvorrichtung 21 verbunden und durch diese von der Fördertrommel 2 etwa radial abhebbar geführt, wobei die den Führungsspalt 10 erzeugenden Druckbogen 4 eine Dicke bis etwa 2mm aufweisen.
Dabei ist es notwendig, dass der vom Anschlag an dem Führungsspalt 10 gegenüberliegende Endabschnitt 20 des Leitorgans 19 durch einen etwa tangentialen Verlauf gegen die Fördertrommel 2 mit einer Erweiterung des Führungsspaltes 10 ausgebildet ist.
Die als Rollenführung dargestellte Führungsvorrichtung 21 weist eine an der Unterseite des Tisches 7 des Bogenmagazins 6 befestigte Rollenbahn 22 auf, in welcher mit dem Leitorgan 19 verbundene Laufrollen 23 angeordnet sind. Ein durch einen zur Rollenbahn 22 parallel verlaufender Schlitz 24 bildet dabei für einen mit dem Leitorgan 19 verbundenen Anschlagbolzen 25 die maximale Abhebestrecke des Leitorgans 19 von der Fördertrommel 2, wobei ein Abheben des Leitorgans 19 von der Fördertrommel 2 von mehr als der Dicke der Druckbogen 4 der Entnahme der Druckbogen 4 im Störungsfall dient.
Selbstverständlich könnten die Laufrollen 23 umgekehrt auch mit dem stationären Tisch 7 und die Rollenführung 22 mit dem Leitorgan 19 verbunden sein. Die Bewegungsrichtung der Führungsanordnung 1 oder der mit letzterer resp. dem Leitorgan 19 verbundenen Führungsvorrichtung 21 schliesst mit einer durch die Drehachse der Fördertrommel 2 verlaufenden Horizontalebene einen Winkel von etwa 30°, jedoch maximal 45° ein.The single figure shows a guide arrangement 1 on the conveyor drum 2 of a printing sheet feeder 3 for a saddle stitcher (not shown), as is disclosed for example in the Swiss patent specifications 586 611, 617 905 and 652 103. This feeder 3 is used to load a collecting section of a saddle stitcher and consists of a rotating conveyor drum 2, which pulls the printing sheets folded in advance from a stack 5 of an adjacent sheet magazine 6, of which the table 7 is shown in the figure, which one part of the individual printing sheets 4 from the underside of the stack lifting device and a gripping device (both not shown) which detects the lifted sheet parts are assigned, and a stop device 8 which is arranged on the orbit of the sheet 4 and which stops the fold, which cooperates with an upstream guide arrangement 9, which forms a guide gap 10 with the conveyor drum 2. This guide arrangement 1 also acts on the printed sheets 4 when they are picked up by the opening device (not shown) and transported in the opposite direction to the collecting section.
The printed sheets 4 fed to the stop or the stop device 8 lift the guide arrangement 9 off the conveyor drum 2, this taking place against a force formed on the guide arrangement 9 from gravitation and / or against a spring force. The stationary stop device 8 is preceded by a guide roller 10, which is freely rotatably mounted on a lever 12 and is set in rotation by the printed sheet 4 in the guide gap 10. In the rest position, the guide roller 11 is in contact with the conveyor drum 2 by a compression spring 13 acting on the lever 12.
The stop device 8 has an access opening 14 leading to the stop, which is designed to be adjustable on the one hand by a bottom guide surface which is curved from below to a lower guide surface aligned with the conveying drum 2 and on the other hand by the lower edge of the lever 12. The stop itself is constructed by a stop element 15 made of rubber or a rubber alloy that dampens the impact of the printed sheets 4. To limit the access opening 14, a recess 16 on the lever 12 is provided with a cam 17 which is assigned to an end stop 18 on the stop device 8.
Furthermore, the guide arrangement 1 has a guide element 19 which, with the exception of the end section 20 facing away from the stop, runs approximately parallel to the circumference of the conveyor drum 2 along the length of the guide gap 10.
The lower edge of the lever 12 forms a section of the guide gap 10 between the stop and the guide roller 11, the guide roller 11 being adjustable, for example by means of a, for adjusting the passage width of the section mentioned eccentrically rotatable shaft on which lever 12 is mounted. The guide member 19 is in turn connected to a guide device 21 and guided by this approximately radially liftable from the conveyor drum 2, the printed sheets 4 producing the guide gap 10 having a thickness of up to approximately 2 mm.
It is necessary that the end section 20 of the guide member 19 opposite the stop on the guide gap 10 is formed with an approximately tangential course against the conveyor drum 2 with an expansion of the guide gap 10.
The guide device 21 shown as a roller guide has a roller conveyor 22 fastened to the underside of the table 7 of the sheet magazine 6, in which rollers 23 connected to the guide element 19 are arranged. A slot 24 running parallel to the roller conveyor 22 forms the maximum lifting distance of the guide member 19 from the conveyor drum 2 for a stop pin 25 connected to the guide member 19, whereby the guide member 19 is lifted off the conveyor drum 2 by more than the thickness of the printed sheets 4 the removal of the printed sheets 4 in the event of a fault.
Of course, the rollers 23 could conversely also be connected to the stationary table 7 and the roller guide 22 to the guide member 19. The direction of movement of the guide arrangement 1 or with the latter, respectively. The guide device 21 connected to the guide member 19 forms an angle of approximately 30 °, but a maximum of 45 °, with a horizontal plane running through the axis of rotation of the conveyor drum 2.
