Abstract

The individually controllable grippers (14) are partially opened as soon as the leading, open edge (30) of the folded printed product (24) in question reaches the region of the alignment device (28). The printed products (24) slide in the mouth (22) in the direction of the arrow (F) until the open edge (30) strikes an alignment cam (38). The alignment cams (38) are driven so as to rotate at a slightly slower speed than that of the grippers (14), so that the printed products (24) are once again pushed towards the inside of the mouth (22), for alignment. As soon as the open side edge (30) has reached the end of the alignment device (28), the corresponding alignment cam (38) leaves the edge (30) and the gripper (14) in question is closed, to convey the aligned printed product (24) further. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bearbeiten von Druckereiprodukten, wie Zeitungen, Zeitschriften oder Teilen davon, gemäss dem Oberbegriff des Anspruchs 1 bzw. 6.6. The present invention relates to a method and a device for processing printed products, such as newspapers, magazines or parts thereof, according to the preamble of claims 1 and 6, respectively.

Ein Verfahren und eine Vorrichtung dieser Art sind aus der EP-A-0 208 081 bzw. der entsprechenden US-A-4,684,116 und US-A-4,684,117 bekannt. Die aussermittig gefalteten Druckereiprodukte werden von einzeln steuerbaren Greifern einer Fördereinrichtung beim Falz gehalten und mit vorlaufendem, dem Falz gegenüberliegendem offenem Randbereich mit schräg von oben gegen unten verlaufender Förderrichtung transportiert. Unterhalb der Fördereinrichtung befindet sich eine Oeffnungseinrichtung mit an zwei zueinander parallel umlaufenden Zugorganen angeordneten steuerbaren Oeffnungsgreifern. Um den Randbereich in den Wirkbereich der Oeffnungsgreifer zu bringen, wird jeweils der entsprechende Greifer kurzzeitig geöffnet, so dass das Druckereiprodukt mit dem jeweils untenliegenden Produkteteil in das Maul der Oeffnungsgreifer gleitet. Der vom Oeffnungsgreifer im Randbereich nun gehaltene Produkteteil wird beim Umlenken des Zugorgans um ein Umlenkrad quer zur Förderrichtung vom obenliegenden, nicht gehaltenen Produkteteil wegbewegt. Zwischen die derart teilweise voneinander abgehobenen Produkteteile wird von unten ein Sammelförderer eingeführt, auf den das Druckereiprodukt rittlingsweise fällt, wenn der Greifer geöffnet wird.A method and a device of this type are known from EP-A-0 208 081 or the corresponding US-A-4,684,116 and US-A-4,684,117. The eccentrically folded printed products are held by individually controllable grippers of a conveying device during the folding and transported with a leading, open edge area opposite the fold with a conveying direction that runs obliquely from top to bottom. Below the conveying device is an opening device with controllable opening grippers arranged on two traction elements rotating in parallel to one another. In order to bring the edge area into the effective area of the opening gripper, the corresponding gripper is briefly opened, so that the printed product with the product part below it slides into the mouth of the opening gripper. The product part now held by the opening gripper in the edge area is moved away from the overhead product part which is not held transversely to the conveying direction when the pulling element is deflected by a deflection wheel. Between the product parts, which are partially lifted off each other in this way, a collecting conveyor is inserted from below, onto which the printed product falls astride when the gripper is opened.

Werden Druckereiprodukte mittels Fördereinrichtungen mit einzeln steuerbaren Greifern transportiert, ist die Lage jedes Druckereiproduktes bezüglich des betreffenden Greifers durch die Lage des Druckereiproduktes beim Erfassen durch den Greifer bestimmt. Die Druckereiprodukte weisen deshalb oft bezüglich ihrer Greifer unterschiedliche Lagen auf. Für die Weiterverarbeitung der Druckereiprodukte kann es aber von Bedeutung sein, dass alle Druckereiprodukte eine genau definierte Lage einnehmen.If printed products are transported by means of conveyors with individually controllable grippers, the position of each printed product with respect to the gripper in question is determined by the position of the printed product when it is gripped by the gripper. The printed products therefore often have different positions with regard to their grippers. For the further processing of the printed products, however, it can be important that all printed products are in a precisely defined position.

Es ist deshalb Aufgabe der vorliegenden Erfindung, ein Verfahren zum genauen Positionieren von Druckereiprodukten bezüglich steuerbaren Greifern, mittels welchen sie transportiert werden, vorzuschlagen und eine entsprechende Einrichtung zu schaffen.It is therefore an object of the present invention to propose a method for precisely positioning printed products with respect to controllable grippers by means of which they are transported and to create a corresponding device.

Diese Aufgabe wird durch ein Verfahren, das die Merkmale des Anspruchs 1 und eine Vorrichtung, die die Merkmale des Anspruchs 6 aufweist, gelöst.This object is achieved by a method which has the features of claim 1 and a device which has the features of claim 6.

Die Druckereiprodukte verbleiben während des Ausrichtens im Maul der Greifer und werden anschliessend vom selben Greifer weitertransportiert. Zum Ausrichten werden die Druckereiprodukte mit jener Kante an ein Richtmittel zur Anlage gebracht, welche für die Weiterverarbeitung der Druckereiprodukte lagebestimmend ist.The printed products remain in the gripper's mouth during alignment and are then transported on by the same gripper. For the alignment, the printed products are brought into contact with a straightening means with the edge which determines the position for the further processing of the printed products.

Ein derartiges Richten der Druckereiprodukte ist besonders vorteilhaft, wenn die Druckereiprodukte einer Oeffnungseinrichtung zugeführt werden, welche zum Oeffnen jeweils einen Teil des Druckereiproduktes im Bereich der Kante erfasst, nach welcher vorgängig die Druckereiprodukte ausgerichtet wurden. Dies stellt ein zuverlässiges Oeffnen jedes Druckereiproduktes sicher.Such straightening of the printed products is particularly advantageous if the printed products are fed to an opening device which, for opening, detects a part of the printed product in the region of the edge, according to which the printed products were previously aligned. This ensures reliable opening of every printed product.

Da die Lage der Druckereiprodukte nach dem Richten bezüglich der Greifer genau definiert ist, kann die Weiterverarbeitungsstation, wie beispielsweise die Oeffnungseinrichtung, in einem beliebigen Abstand in Förderrichtung der Richteinrichtung nachgeschaltet sein.Since the position of the printed products after the straightening is precisely defined with respect to the grippers, the further processing station, such as the opening device, can be connected downstream of the straightening device at an arbitrary distance in the conveying direction.

Bevorzugte Weiterbildungen des erfindungsgemässen Verfahrens und bevorzugte Ausführungsformen der erfindungsgemässen Vorrichtung sind in den abhängigen Ansprüchen angegeben.Preferred developments of the method according to the invention and preferred embodiments of the device according to the invention are specified in the dependent claims.

Aus der CH-PS 667 859 ist eine Vorrichtung zum Oeffnen von mit einem Falz versehenen Druckereiprodukten bekannt. Die Druckereiprodukte werden beim Falz von den Greifern einer Fördereinrichtung verdrehsicher gehalten und mittels eines Drückers, der auf einen Endbereich des Falzes einwirkt, gestaucht. Zwischen die vom gestauchten Falz ausgehenden Hälften der Druckereiprodukte wird eine Oeffnungsleiste eingeführt, die zum Voneinander-Abheben der beiden Hälften vom Bereich des Falzes her, entlang der betreffenden Seitenkante der Druckereiprodukte, zum Bereich der dem Falz gegenüberliegenden offenen Seitenkante verschoben wird. Um die Druckereiprodukte verdrehsicher zu halten, weisen die Greifer je zwei unabhängig voneinander steuerbare Klemmfinger und eine mit beiden Klemmfingern zusammenwirkende Klemmbacke auf. Um die Druckereiprodukte fertig zu öffnen, wird der dem Drücker nähere Klemmfinger in seine Offenstellung überführt und das betreffende Druckereiprodukt durch Einwirkung des Drückers auf den Falz schräg gestellt, um die offenen Kanten der einen Hälfte des Druckereiproduktes in einen umlaufenden Oeffnungsnocken einzuführen. Die vom Oeffnungsnocken gehaltene Druckereiproduktehälfte wird dann umgelenkt, um von der andern Hälfte bereichsweise abgehoben zu werden, so dass zwischen die beiden Hälften eine sattelförmige Auflage einer Sammeltrommel einfahren kann. Durch Oeffnen des andern Klemmfingers fällt dann das Druckereiprodukt rittlingsweise auf die sattelförmige Auflage. Mit der bekannten Vorrichtung können die Druckereiprodukte nicht für eine nachfolgende Weiterverarbeitung ausgerichtet werden, weil die geöffneten Druckereiprodukte unter der Einwirkung des Drückers sich verformen.From CH-PS 667 859 an apparatus for opening a printed product with a fold is known. When folding, the printed products are held against rotation by the grippers of a conveying device and compressed using a pusher which acts on an end region of the fold. An opening strip is placed between the halves of the printed products originating from the compressed fold introduced, which is moved from the area of the fold, along the relevant side edge of the printed products, to the area of the open side edge opposite the fold to lift the two halves apart. In order to keep the printed products twist-proof, the grippers each have two independently controllable clamping fingers and a clamping jaw that interacts with both clamping fingers. In order to open the printed products completely, the clamping finger closer to the pusher is moved into its open position and the print product in question is inclined by the action of the pusher on the fold in order to insert the open edges of one half of the printed product into a circumferential opening cam. The printed product half held by the opening cam is then deflected in order to be lifted off in regions from the other half, so that a saddle-shaped support of a collecting drum can move between the two halves. By opening the other clamping finger, the printed product falls astride the saddle-shaped pad. With the known device, the printed products cannot be aligned for subsequent further processing because the opened printed products deform under the action of the pusher.

Die vorliegende Erfindung wird nun anhand eines in der Zeichnung gezeigten Ausführungsbeispiels näher beschrieben. Es zeigen rein schematisch:

Derartige Fördereinrichtungen 10 sind allgemein bekannt und beispielsweise in der CH-PS 644 816 bzw. der entsprechenden US-PS 4,381,056 ausführlich beschrieben. Was die genaue Ausbildungsform der Fördereinrichtung 10 und der Greifer 14 betrifft, wird deshalb ausdrücklich auf diese Dokumente verwiesen.The present invention will now be described with reference to an embodiment shown in the drawing. It shows purely schematically:
Figure 1

The conveyor device 10 has an individually controllable gripper 14, arranged at a fixed distance A, on an endless traction element 12, indicated by dash-dotted lines in FIG. 1 and driven in rotation in the conveying direction F. Such conveyors 10 are generally known and are described in detail, for example, in CH-PS 644 816 and the corresponding US-PS 4,381,056. With regard to the exact form of training of the conveyor 10 and the gripper 14, reference is therefore expressly made to these documents.

Die Förderrichtung F verläuft im Bereich einer unterhalb der Fördereinrichtung 10 angeordneten Richteinrichtung 28 von oben schräg nach unten, und die Greifer 14 transportieren die Druckereiprodukte 24 in Hängelage, so dass die dem Falz 26 gegenüberliegende offene Seitenkante 30 jedes Druckereiproduktes 24 bezüglich dem Falz 26 vorlaufend ist. Dabei gleiten die Druckereiprodukte 24 mit ihrem vorlaufenden Endbereich auf bezüglich der Fördereinrichtung 10 seitlichen Führungsstäben 32, die ungefähr parallel zur Förderrichtung F verlaufen, wie dies in den Figuren 1 bis 3 gezeigt ist.Each of the grippers 14 has a jaw 22 delimited by a clamping jaw 18 and a clamping finger 20 cooperating therewith, in which a folded printed product 24 such as a magazine, a newspaper, parts thereof or the like in the region of the conveyor-effective path of the conveyor device 10 Fold 26 is held. The conveying direction F runs obliquely downwards in the region of a straightening device 28 arranged below the conveying device 10, and the grippers 14 transport the printed products 24 in a hanging position, so that the open side edge 30 of each printed product 24 opposite the fold 26 is leading with respect to the fold 26 . In this case, the printing products 24 slide with their leading end region onto guide rods 32 which are lateral with respect to the conveying device 10 and which run approximately parallel to the conveying direction F, as is shown in FIGS. 1 to 3.

Die Richteinrichtung 28 weist zwischen den Führungsstäben 32 zwei zueinander parallele und, in Förderrichtung F gesehen, seitlich voneinander beabstandete Kettenrundläufe 34, 34' mit an den endlosen Ketten 36 in einem festen Abstand B hintereinander angeordneten, als Richtnocken 38 ausgebildete Richtmittel 39, auf. Die Ketten 36 sind um strichpunktiert angedeutete Kettenräder 40 geführt (Figur 1), die etwa in Förderrichtung F voneinander beabstandet sind und die derart an einem schematisch angedeuteten Gestell 42 gelagert sind, dass der obere, der Fördereinrichtung 10 zugewandte Trum 36' mit einem kleinen Abstand unterhalb der Führungsstäbe 32 verläuft, so dass die Druckereiprodukte 24 in den seitlichen Endbereichen der vorauslaufenden offenen Kante 30 zur Verbesserung der Stabilität leicht aufwärts gebogen sind, wie dies aus den Figuren 2 und 3 besonders gut ersichtlich ist.The straightening device 28 has between the guide rods 32 two parallel and, seen in the conveying direction F, laterally spaced chain rotations 34, 34 'with one another on the endless chains 36 arranged at a fixed distance B one behind the other, designed as straightening cams 38. The chains 36 are guided around chain wheels 40 indicated by dash-dotted lines (FIG. 1), which are spaced apart approximately in the conveying direction F and which are mounted on a schematically indicated frame 42 in such a way that the upper run 36 ′ facing the conveying device 10 is at a small distance runs below the guide rods 32, so that the printed products 24 are slightly bent upward in the lateral end regions of the leading open edge 30 to improve stability, as can be seen particularly well from FIGS. 2 and 3.

Der Abstand B zwischen aufeinanderfolgenden Richtnocken 38 ist etwas kleiner als der Abstand A zwischen aufeinanderfolgenden Greifern 14. Die in der Figur 1 dargestellten oberen Kettenräder 40 stehen über einen nur strichpunktiert angedeuteten Kettentrieb 44 mit einem nicht gezeigten, allgemein bekannten Antrieb für das Zugorgan 12 der Fördereinrichtung 10 derart in Antriebsverbindung, dass sich die Fördergeschwindigkeit v1 der Fördereinrichtung 10 zur Geschwindigkeit v2 der Richtnocken 38 proportional zum Verhältnis des Abstandes A zum Abstand B verhält. Die Richtnocken 38 bewegen sich dabei im Bereich des oberen richtwirksamen Trums 36' in Förderrichtung F und die Synchronisation zwischen der Richteinrichtung 28 und der Fördereinrichtung 10 ist derart eingestellt, dass ein, in Förderrichtung F gesehen, am Ende des Trums 36' ankommender Richtnocken 38 von dem ihm zugeordneten Greifer 14 einen vorbestimmten Sollabstand aufweist. Als zugeordneter Greifer 14 ist jener Greifer 14 zu verstehen, der dasjenige Druckereiprodukt 24 transportiert, welches mit seiner vorauslaufenden offenen Kante 30 an den betreffenden Richtnocken 38 der beiden Kettenrundläufe 34, 34' anliegt.The distance B between successive straightening cams 38 is somewhat smaller than the distance A between successive grippers 14. The upper chain wheels 40 shown in FIG. 1 are above a chain drive 44, indicated only by dash-dotted lines, with a generally known drive (not shown) for the traction element 12 of the conveyor 10 in such a drive connection that the conveying speed v1 of the conveying device 10 to the speed v2 of the directional cams 38 is proportional to the ratio of the distance A to the distance B. The straightening cams 38 move in the region of the upper directionally effective strand 36 'in the conveying direction F and the synchronization between the straightening device 28 and the conveying device 10 is set such that, viewed in the conveying direction F, a straightening cam 38 arriving at the end of the strand 36' the gripper 14 assigned to it has a predetermined target distance. An assigned gripper 14 is understood to be that gripper 14 which transports the printed product 24 which, with its leading open edge 30, lies against the relevant straightening cams 38 of the two chain runs 34, 34 '.

Die Greifer 14 sind mittels einer weiter unten ausführlich beschriebenen Steuereinrichtung 46 derart steuerbar, dass wenn ein Druckereiprodukt 24 mit seiner vorauslaufenden Kante 30 sich im Bereich des oberen Trums 36' befindet, sein Maul 22 teilweise öffnet, so dass das betreffende Druckereiprodukt 24 unter seinem Eigengewicht in Förderrichtung F nach vorne rutscht und an die betreffenden Richtnocken 38 der beiden Kettenrundläufe 34, 34' zur Anlage kommt. Dabei verschiebt sich das Druckereiprodukt 24 im Maul 22 in Richtung gegen aussen, ohne aber ausser Eingriff zu gelangen, wie dies in der Figur 1 am, in Förderrichtung F gesehen, zweit hintersten Greifer gezeigt ist. Da sich nun die Richtnocken 38 mit der Geschwindigkeit v2 bewegen, die geringfügig kleiner ist als die Fördergeschwindigkeit v1, wird das betreffende Druckereiprodukt 24 wieder solange in Richtung gegen das Innere des Maules 22 geschoben, bis die Richtnocken 38 das Ende des Trums 36' erreicht haben und um die unteren Kettenräder 40 aus dem Einwirkbereich auf die Druckereiprodukte 24 gelenkt werden. Dabei wird kurz bevor die Richtnocken 38 ab der offenen Kante 30 des Druckereiproduktes 24 ablaufen, der betreffende Greifer 14 wieder geschlossen, um das nun ausgerichtete Druckereiprodukt 24 in Förderrichtung F einer Weiterverarbeitung zuzuführen. Jedes die Richteinrichtung 28 verlassende Druckereiprodukt 24 hat somit gegenüber dem Greifer 14 eine genau definierte Lage.The grippers 14 can be controlled by means of a control device 46, which is described in detail below, such that when a printed product 24 with its leading edge 30 is in the region of the upper run 36 ', its mouth 22 partially opens, so that the printed product 24 in question is under its own weight slides forward in the direction of conveyance F and comes to rest against the relevant directional cams 38 of the two chain circuits 34, 34 '. The printed product 24 in the mouth 22 moves towards the outside, but without disengaging, as shown in FIG. 1 on the second rear gripper, seen in the conveying direction F. Since the straightening cams 38 now move at the speed v2, which is slightly less than the conveying speed v1, the printed product 24 in question is again pushed towards the inside of the mouth 22 until the straightening cams 38 have reached the end of the run 36 ' and are steered around the lower sprockets 40 from the area affected by the printed products 24. Shortly before the straightening cams 38 run from the open edge 30 of the printed product 24, the gripper 14 in question is closed again in order to feed the now aligned printed product 24 in the conveying direction F for further processing. Each printed product 24 leaving the straightening device 28 thus has a precisely defined position relative to the gripper 14.

Um die Druckereiprodukte 24 mit ihrer offenen vorlaufenden Kante 30 genau rechtwinklig zur Förderrichtung F auszurichten, sind die einander entsprechenden Richtnocken 38 der beiden Kettenrundläufe 34, 34' derart ausgerichtet, dass sie auf einer rechtwinklig zur Förderrichtung F verlaufenden Linie liegen, wie dies Figur 2 zeigt. Ist hingegen die offene Kante 30 schräg zur Förderrichtung F auszurichten, so sind die Richtnocken 38 der beiden Kettenrundläufe 34, 34' gegeneinander in Förderrichtung F entsprechend versetzt, wie dies Figur 3 zeigt. Dabei ist, in Förderrichtung F gesehen, die von der offenen Kante 30 und der linken Seitenkante 48 des Druckereiproduktes 24 gebildete Ecke 48' vorlaufend.In order to align the printed products 24 with their open leading edge 30 exactly at right angles to the conveying direction F, the corresponding directional cams 38 of the two chain rotors 34, 34 'are aligned such that they lie on a line running at right angles to the conveying direction F, as shown in FIG. 2 . If, on the other hand, the open edge 30 is to be aligned obliquely to the conveying direction F, the straightening cams 38 of the two chain rotors 34, 34 'are mutually offset in the conveying direction F, as shown in FIG. 3. As seen in the conveying direction F, the corner 48 ′ formed by the open edge 30 and the left side edge 48 of the printed product 24 is leading.

Die gerichteten Druckereiprodukte 24 werden durch die Fördereinrichtung 10 einer der Richteinrichtung 28 mit Abstand nachgeschalteten Oeffnungseinrichtung 50 zugeführt. Im Bereich zwischen der Richteinrichtung 28 und der Oeffnungseinrichtung 50 sind Führungsmittel 52 für die vorauslaufenden offenen Kanten 30 und die daran anschliessenden Bereiche der Druckereiprodukte 24 vorgesehen. Die Führungsmittel 52 umfassen ein Leitblech 52' und können zusätzlich ein über das Leitblech 52' und um die Oeffnungswalze 54 der Oeffnungseinrichtung 50 sowie eine in der Figur 1 nicht gezeigte gleichachsig zum unteren Kettenrad 40 gelagerte Umlenkwalze geführtes Bändchen 56 aufweisen.The directional printed products 24 are fed by the conveying device 10 to an opening device 50 which is arranged at a distance from the straightening device 28. In the area between the straightening device 28 and the opening device 50, guide means 52 are provided for the leading open edges 30 and the adjoining areas of the printed products 24. The guide means 52 comprise a guide plate 52 'and can additionally have a ribbon 56 which is guided over the guide plate 52' and around the opening roller 54 of the opening device 50 and a deflection roller, which is not shown in FIG.

Entlang dem Umfang der Oeffnungswalze 54 sind in bekannter Art und Weise steuerbare Oeffnungsnocken 58 verteilt angeordnet, wobei die Umfangsgeschwindigkeit v3 der Oeffnungswalze 54 mit der Fördergeschwindigkeit v1 der Fördereinrichtung 10 übereinstimmt ist (v1 = v3), und die gegenseitige Phasenlage der Fördereinrichtung 10 und der Offnungswalze 54 darauf eingestellt ist, dass die vorlaufende offene Kante 30 jedes Druckereiproduktes 24 in den Wirkbereich eines Oeffnungsnockens 58 kommt. Die Oeffnungsnocken 58 erfassen jeweils die untere, der Oeffnungswalze 54 zugewandte Hälfte 24' des Druckereiproduktes 24 und halten diese im Bereich der offenen Kante 30 an der Oeffnungswalze 54 fest, so dass durch die Umlenkung um die Oeffnungswalze 54 die obere, nicht erfasste Hälfte 24'' des Druckereiproduktes 24 von der offenen Kante 30 her beginnend sich von der erfassten Hälfte 24' abhebt. Zwischen die voneinander abgehobenen Druckereiproduktehälften 24', 24'' fährt von unten her entgegen dem Drehsinn der Oeffnungswalze 54 ein Offenhaltestift 60 ein, der an einem in Umlaufrichtung C angetriebenen, strichpunktiert angedeuteten Zugelement 62 angeordnet ist, wobei das Zugelement 62 in Förderrichtung F gesehen, der Oeffnungswalze 54 nachfolgend etwa parallel zur Fördereinrichtung 10 geführt ist, um die geöffneten Druckereiprodukte 24 während des Weitertransports offen zu halten. Sobald der Offenhaltestift 60 zwischen die Druckereiproduktehälften 24', 24'' eingefahren ist, gibt der betreffende Oeffnungsnocken 58 die erfasste Hälfte 24' des Druckereiproduktes 24 frei.Controllable opening cams 58 are arranged in a known manner along the circumference of the opening roller 54, the peripheral speed v3 of the opening roller 54 coinciding with the conveying speed v1 of the conveying device 10 (v1 = v3), and the mutual phase position of the conveying device 10 and the opening roller 54 is set such that the leading open edge 30 of each printed product 24 comes into the effective range of an opening cam 58. The opening cams 58 each grasp the lower half 24 'of the printed product 24 facing the opening roller 54 and hold it in the region of the open edge 30 on the opening roller 54, so that the upper, undetected half 24' is deflected around the opening roller 54 'of the printed product 24 starting from the open edge 30 stands out from the detected half 24'. Between the printed product halves 24 ', 24'', which are lifted from each other, a hold-open pin 60 is inserted from below, counter to the direction of rotation of the opening roller 54, which is arranged on a tension element 62 which is driven in the direction of rotation C and is indicated by dash-dotted lines, the tension element 62 viewed in the direction of conveyance F, the opening roller 54 is subsequently guided approximately parallel to the conveying device 10 in order to keep the opened printed products 24 open during further transport. As soon as the hold-open pin 60 is inserted between the printed product halves 24 ', 24'', the opening cam 58 in question releases the detected half 24' of the printed product 24.

Es ist durchaus denkbar, dass die Oeffnungseinrichtung 50 bezüglich der Fördereinrichtung¹⁰ seitlich versetzt angeordnet ist, um die Druckereiprodukte 24 einseitig zu öffnen. Selbstverständlich ist in diesem Fall das Zugelement 62 auf jener Seite von den Druckereiprodukten geführt, auf welcher diese geöffnet werden. Bei in der Richteinrichtung 28 schräg ausgerichteten Druckereiprodukten 24, wie dies Figur 3 zeigt, befindet sich die Oeffnungswalze 54 vorzugsweise im Bereich der vorlaufenden Ecke 48', um die Druckereiprodukte 24 im Bereich dieser Ecke 48' zu öffnen.It is quite conceivable that the opening device 50 is arranged laterally offset with respect to the conveyor device in order to open the printed products 24 on one side. In this case, of course, the tension element 62 is guided on the side of the printed products on which these are opened. In the case of printed products 24 oriented obliquely in the straightening device 28, as shown in FIG. 3, the opening roller 54 is preferably located in the region of the leading corner 48 'in order to open the printed products 24 in the region of this corner 48'.

Das Trennen der Richteinrichtung 28 von der Oeffnungseinrichtung 40 führt zu einer übersichtlichen Konstruktion und vereinfacht das Einstellen der Richteinrichtung 28 und Oeffnungseinrichtung 50 auf unterschiedliche Formate der Druckereiprodukte 24. Falls die Länge der Druckereiprodukte 24 in Richtung rechtwinklig zum Falz 26 gesehen ändert, ist einzig die Phasenlage zwischen den Greifern 14 und den Richtnocken 38 sowie gegebenenfalls den Oeffnungsnocken 58 anzupassen.The separation of the straightening device 28 from the opening device 40 leads to a clear construction and simplifies the adjustment of the straightening device 28 and opening device 50 to different formats of the printed products 24. If the length of the printed products 24 changes in the direction perpendicular to the fold 26, only the phase position is to adapt between the grippers 14 and the directional cams 38 and, if appropriate, the opening cams 58.

Wie dies aus den Figuren 2 und 3 ersichtlich ist, handelt es sich beim Zugorgan 12 um eine, in einer C-förmigen in sich geschlossenen Schiene 64 mit Rollen 66 geführte, allgemein bekannte Gliederkette mit Auslegern 68, welche den in Längsrichtung der Schiene 64 verlaufenden Schlitz der Schiene 64 durchdringen und im Abstand A (Mittenabstand) zueinander angeordnet sind. An jedem Ausleger 68 ist ein Greifer 14 um eine rechtwinklig zur Förderrichtung F verlaufende Achse 70 schwenkbar angeordnet. Die um diese Achse 70 schwenkbare, steif ausgebildete Klemmbacke 18 weist eine, bezüglich der Achse 70 exzentrische, drehbar gelagerte Lagerolle 72 auf, die mit einer Lagekulisse 74 zusammenwirkt. Der als Blattfeder ausgebildete Klemmfinger 20 ist mit seinem inneren Ende an einer um die Achse 70 drehbaren Welle 76 befestigt und von dieser Welle 76 steht auf der der Lagerolle 72 abgewandten Seite ein gekröpfter Steuerhebel 78 drehfest ab, an dessen freiem Ende eine Steuerrolle 80 drehbar gelagert ist. Diese Steuerrolle 80 wirkt mit einer in der Figur 1 nur schematisch angedeuteten Schliesskulisse 82 zusammen. An der Klemmbacke 18 ist weiter ein Verriegelungshebel 84 schwenkbar gelagert, der mit einer in den Figuren nicht gezeigten Rastnase am Steuerhebel 78 zusammenwirkt und mittels einer angedeuteten Oeffnungskulisse 86 aus der Verriegelungsstellung in eine Lösestellung überführbar ist. In der Geschlossenstellung der Greifer 14 ist der Klemmfinger 20 gegen die Klemmbacke 18 vorgespannt und diese sind über den Verriegelungshebel 84 und die Rastnase gegeneinander verriegelt. In diesem Zustand sind die Greifer 14 zusammen mit dem im Maul 22 gehaltenen Druckereiprodukt 24 um die Achse 70 frei schwenkbar, soweit dies die Lagekulisse 74 und gegebenenfalls die Schliesskulisse 82 erlaubt.As can be seen from FIGS. 2 and 3, the traction element 12 is a generally known link chain with arms 68, which is guided in a C-shaped, self-contained rail 64 with rollers 66 and which extends in the longitudinal direction of the rail 64 Pass through the slot of the rail 64 and are arranged at a distance A (center distance) from one another. A gripper 14 is arranged on each boom 68 so as to be pivotable about an axis 70 running at right angles to the conveying direction F. The rigidly designed clamping jaw 18, which can be pivoted about this axis 70, has a bearing roller 72 which is rotatable and is eccentric with respect to the axis 70 and which cooperates with a position link 74. The clamping finger 20, which is designed as a leaf spring, is fastened with its inner end to a shaft 76 rotatable about the axis 70, and from this shaft 76 a cranked control lever 78 protrudes from the side facing away from the bearing roller 72, and a control roller 80 is rotatably mounted on its free end is. This control roller 80 interacts with a closing link 82, which is only schematically indicated in FIG. 1. A locking lever 84 is also pivotably mounted on the clamping jaw 18 and has a locking lug on the control lever, not shown in the figures 78 cooperates and can be transferred from the locking position into a release position by means of an indicated opening gate 86. In the closed position of the grippers 14, the clamping finger 20 is prestressed against the clamping jaw 18 and these are locked against one another via the locking lever 84 and the latching lug. In this state, the grippers 14, together with the printed product 24 held in the mouth 22, can be freely pivoted about the axis 70, insofar as the positional link 74 and possibly the closing link 82 allow this.

Beim Bewegen eines Greifers 14 in Förderrichtung F gegen die Richteinrichtung 28 rollt die Lagerolle 72 entlang der Lagekulisse 74 und die Steuerrolle 80 läuft auf die Schliesskulisse 82 auf. Durch Verschwenken des Verriegelungshebels 84 durch die Oeffnungskulisse 86 wird die gegenseitige Verriegelung der Klemmbacke 18 und des Klemmfingers 20 gelöst, wobei sich nun aber das Maul 22 des Greifers 14 noch nicht öffnet, da die gegeneinander wirkenden Lagekulisse 74 und Schliesskulisse 82 den Klemmfinger 20 noch vorgespannt gegen die Klemmbacke 18 drücken. Ueber die Schliesskulisse 82 wird nun der Klemmfinger 20 soweit entlastet, dass die Vorspannung in Richtung gegen die Klemmbacke 18 aufgehoben ist und die Klemmbacke 18 nur noch mit ihrem am freien Ende wirkenden Gewicht auf das im Maul 22 gehaltene Druckereiprodukt 24 einwirkt, welches nun durch sein Eigengewicht im Maul 22 in Richtung gegen aussen rutscht, bis es mit seiner vorlaufenden offenen Kante 30 auf die entsprechenden Richtnocken 38 der Richteinrichtung 28 zur Anlage kommt. Zum nachträglichen Schliessen der nicht ganz geöffneten Greifer 14 wird durch Einwirkung der Schliesskulisse 82 auf die Steuerrolle 80 die Welle 76 im Uhrzeigersinn (Figur 1) verschwenkt, bis die Rastnase am Steuerhebel 78 am Verriegelungshebel 84 wieder einrastet. Dies ist spätestens der Fall, wenn die offene Seitenkante 30 von den Richtnocken 38 freigegeben wird. Die die Lagekulisse 74, die Schliesskulisse 82 und Oeffnungskulisse 86 umfassende Steuereinrichtung 46 sorgt somit im Bereich der Richteinrichtung 28 für das lagegerechte, nur teilweise Oeffnen und wieder Schliessen der Greifer 14 sowie das in der gewünschten Lage Halten der Greifer 14.When a gripper 14 is moved in the conveying direction F against the straightening device 28, the bearing roller 72 rolls along the position link 74 and the control roller 80 runs onto the closing link 82. By pivoting the locking lever 84 through the opening link 86, the mutual locking of the clamping jaw 18 and the clamping finger 20 is released, but the mouth 22 of the gripper 14 does not open yet, since the opposing position link 74 and closing link 82 still pre-tension the clamping finger 20 press against the jaw 18. Via the closing link 82, the clamping finger 20 is now relieved to such an extent that the pretension in the direction against the clamping jaw 18 is released and the clamping jaw 18 only acts on the printed product 24 held in the mouth 22 with its weight acting at the free end, which now acts through The dead weight in the mouth 22 slips outwards until the leading open edge 30 comes into contact with the corresponding straightening cams 38 of the straightening device 28. To subsequently close the grippers 14, which are not fully open, the action of the closing link 82 on the control roller 80 pivots the shaft 76 clockwise (FIG. 1) until the locking lug on the control lever 78 engages again on the locking lever 84. This is the case at the latest when the open side edge 30 is released by the directional cams 38. The control device 46 comprising the positional backdrop 74, the closing backdrop 82 and the opening backdrop 86 thus ensures in the region of the straightening facility 28 that the grippers 14 are opened and closed only partially and closed again, and that the grippers 14 are held in the desired position.

In der Figur 2 ist strichpunktiert ein Verschiebemittel 90 angedeutet, welches beispielsweise ein mit einer Unterdruckquelle verbundenes, in Förderrichtung F umlaufend angetriebenes Lochband sein kann. Dieses dient dazu, die zu richtenden Druckereiprodukte 24 gegen die Richtnocken 38 zu drängen. Derartige Verschiebemittel 90 können notwendig sein, wenn leichte Druckereiprodukte zu verarbeiten sind oder die Förderrichtung F etwa in horizontaler Richtung verläuft.In FIG. 2, a shifting means 90 is indicated by dash-dotted lines, which can be, for example, a perforated belt which is connected to a vacuum source and is driven all the way around in the conveying direction F. This serves to urge the printed products 24 to be straightened against the straightening cams 38. Such displacement means 90 may be necessary if light printed products are to be processed or if the conveying direction F runs approximately in the horizontal direction.

Zum Schrägstellen der Druckereiprodukte 24 ist es auch denkbar, Greifer vorzusehen, die zwei voneinander beabstandete, einzeln steuerbare Klemmfinger aufweisen; dabei ist in der Richteinrichtung 28 nur ein einziger Kettenrundlauf, in der Figur 3 der Kettenrundlauf 34 vorzusehen. In diesem Fall wird zum Schrägstellen eines Druckereiproduktes 24 nur der eine Klemmfinger, vorzugsweise der dem Kettenrundlauf 34 nähere, geöffnet und das Druckereiprodukt 24 unter Drehen um den Klemmpunkt des andern Klemmfingers an einem Richtnocken des Kettenrundlaufs 34 zur Anlage gebracht.To incline the printed products 24, it is also conceivable to provide grippers which have two spaced apart, individually controllable clamping fingers; only one chain runout is to be provided in the straightening device 28, the chain runout 34 in FIG. In this case, to incline a printed product 24, only one clamping finger, preferably that closer to the chain concentric 34, is opened and the printed product 24 is brought into contact with a straightening cam of the chain concentric 34 by rotating around the clamping point of the other clamping finger.

Es ist auch denkbar, bei einer Fördereinrichtung und einer Richteinrichtung, wie sie in der Figur 1 dargestellt sind, die Greifer entgegen der Förderrichtung F zu bewegen und die Kettenrundläufe im Uhrzeigersinn anzutreiben. Dabei wäre der Abstand B zwischen den Richtnocken grösser zu wählen als der Abstand A zwischen den Greifern und die Kettenrundläufe entsprechend schneller anzutreiben als die Greifer. Sobald die Druckereiprodukte mit ihrer nun nachlaufenden offenen Kante sich im Bereich der Richteinrichtung befinden, wird der betreffende Greifer teilweise geöffnet, so dass das Druckereiprodukt auf die Richtnocken zur Anlage rutscht. Die Richtnocken schieben nun das betreffende Druckereiprodukt in Richtung gegen das Innere des Mauls, solange bis die offene Seitenkante bezüglich dem betreffenden Greifer beim Erreichen des Endes der Richteinrichtung die richtige Lage erreicht hat. Durch Schliessen der Greifer werden die gerichteten Druckereiprodukte weitergefördert.It is also conceivable for one conveyor and one Straightening device, as shown in FIG. 1, to move the grippers counter to the conveying direction F and to drive the chain rotations clockwise. The distance B between the straightening cams would have to be chosen larger than the distance A between the grippers and to drive the chain runs correspondingly faster than the grippers. As soon as the printed products with their now trailing open edge are in the area of the straightening device, the gripper in question is partially opened so that the printed product slides onto the straightening cams to the system. The straightening cams now push the printing product in question towards the inside of the mouth until the open side edge with respect to the gripper in question has reached the correct position when the end of the straightening device has been reached. By closing the grippers, the directional printed products are conveyed further.

Es ist selbstverständlich auch denkbar, die Greifer zum Richten der Druckereiprodukte ganz zu öffnen oder andersartige Greifer vorzusehen.Of course, it is also conceivable to open the grippers completely for straightening the printed products or to provide other types of grippers.

Insbesondere bei horizontaler Förderrichtung bewegen sich die Druckereiprodukte im Maul der Greifer nicht in Richtung gegen aussen, sie werden aber zum Positionieren im Greifer in Richtung gegen das Innere der Greifer geschoben.Particularly when the conveying direction is horizontal, the printed products in the mouth of the grippers do not move towards the outside, but they are pushed towards the inside of the grippers for positioning in the gripper.
