Furthermore, the conveying path 34 between the conveying inlet 26 and the conveying outlet 20 'remains approximately the same regardless of the mutual position of the two conveying arms 22, 24, so that the scale formation of the printed products 30 is maintained even during the movement of the transfer conveyor 20.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum wahlweisen Uberführen von flexiblen, flächigen Erzeugnissen, insbesondere Druckereiprodukten wie Zeitungen, Zeitschriften und dergleichen, aus einer entlang eines ersten Förderweges transportierten Schuppenformation auf einen zweiten Förderweg, gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a device for selectively transferring flexible, flat products, in particular printed products such as newspapers, magazines and the like, from a scale formation transported along a first conveying path to a second conveying path, according to the preamble of claim 1.

Eine Vorrichtung dieser Art ist in der US-PS 2,815,949 offenbart. Diese weist einen Uberführförderer mit zwei gelenkig miteinander verbundenen Förderarmen mit je endlosen, umlaufenden Förderbändern auf, die bei der Gelenkverbindung der Förderarme um gleichachsig gelagerte Walzen geführt sind. Der erste Förderarm ist an seinem förderwirksamen und vom ersten Förderarm entfernten Ende ortsfest gelagert und der zweite Förderarm ist an seinem freien Ende in einer gebogenen Kulisse geführt. An der Welle, an der die Walzen gelagert sind, greift ein andernends schwenkbar gelagertes Kolben-Zylindersystem an, um durch Absenken der Welle das freie Ende des zweiten Förderarms, d.h. den Fördereingang des Uberführförderers, in den Förderweg eines ersten Bandförderers einzuschwenken und die in Schuppenformation auf dem ersten Bandförderer herangeführten Erzeugnisse einem zweiten, dem Uberführförderer nachgeschalteten Bandförderer zuzuführen. Beim Anheben der Welle mittels des Kolben-Zylindersystems wird der Uberführförderer knieartig gebogen und der Fördereingang aus dem Förderbereich des ersten Bandförderers zurückgezogen. Die auf dem ersten Bandförderer herangeführten Erzeugnisse werden dann von diesem weitergefördert. Oberhalb der Förderarme angeordnete Andrückmittel weisen zwei gelenkig miteinander verbundene, bandförderartig ausgebildete, je eigene, endlose, umlaufende Andrückbänder aufweisende Andrückorgane auf, wobei die zusammen mit den entsprechenden Förderbändern der Förderarme einen Förderspalt bildenden Andrückbänder bei der Gelenkverbindung der Andrückorgane um gleichachsige Rollen geführt sind. Die die Rollen tragende Welle ist an einem etwa in Richtung des Kolben-Zylindersystems verlaufenden Stab, der von der Welle der Walzen rechtwinklig absteht, verschiebbar gelagert und gegen letztere vorgespannt, und der Stab ist an einem Schwenklager verschiebbar geführt. Die die entsprechenden Wellen umgreifenden Lagerschilder der Förderarme und schilderartigen Lagerglieder der Andrückorgane sind über Laschen miteinander verbunden.A device of this type is disclosed in U.S. Patent 2,815,949. This has a transfer conveyor with two articulated conveyor arms, each with endless, revolving conveyor belts, which are guided around rollers with the same axis in the articulated connection of the conveyor arms. The first conveyor arm is fixed in place at its end which is effective for conveying and is remote from the first conveyor arm, and the second conveyor arm is guided at its free end in a curved backdrop. On the shaft on which the rollers are mounted, a piston-cylinder system which is pivotally mounted at another end engages in order to pivot the free end of the second conveyor arm, that is to say the conveying inlet of the transfer conveyor, into the conveying path of a first belt conveyor by lowering the shaft, and that in a scale formation Feed products brought in on the first belt conveyor to a second belt conveyor downstream of the transfer conveyor. When lifting the shaft by means of the piston-cylinder system the transfer conveyor is bent knee-like and the feed entrance is withdrawn from the conveying area of the first belt conveyor. The products brought up on the first belt conveyor are then conveyed further by the latter. Pressing means arranged above the conveyor arms have two articulated interconnected, belt conveyor-like, each having their own, endless, circumferential pressure belts, with pressure elements, the pressure belts forming a conveyor gap together with the corresponding conveyor belts of the conveyor arms being guided around coaxial rollers in the articulated connection of the pressure organs. The shaft carrying the rollers is slidably mounted on a rod which extends approximately in the direction of the piston-cylinder system and protrudes at right angles from the shaft of the rollers, and is biased against the latter, and the rod is guided on a pivot bearing so as to be displaceable. The bearing plates of the conveyor arms encompassing the corresponding shafts and plate-like bearing members of the pressing members are connected to one another via tabs.

Dieser Aufbau des Uberführförderers hat zur Folge, dass sich der Förderspalt je nach Schwenklage der Förderarme sowohl in seiner Lage bezüglich der Förderarme als auch in der Spaltdicke ändert. Dies kann dazu führen, dass Erzeugnisse während des Verschwenkens der Förderarme in ihrer gegenseitigen Lage verschoben werden, was eine getaktete Weiterverarbeitung nicht mehr erlauben würde, oder dass sehr dünne Erzeugnisse im Förderspalt nicht richtig gehalten sind. Da die Erzeugnisse Stapelschächten zugeführt werden, ist ihre gegenseitige Lage auch nicht von Bedeutung.This construction of the transfer conveyor has the consequence that the conveying gap changes depending on the pivoting position of the conveying arms both in its position with respect to the conveying arms and in the gap thickness. This can result in products being shifted in their mutual position during the pivoting of the conveyor arms, which would no longer allow timed further processing, or that very thin products are not properly held in the conveyor gap. Since the products are fed into stacking shafts, their mutual position is also irrelevant.

Eine zweckgleiche aber unterschiedlich ausgebildete Vorrichtung ist aus der DE-A-2 820 957 bekannt. Diese weist einen ersten Förderer mit zwei höhenversetzt hintereinandergeschalteten Bandförderern zum Transportieren von in Schuppenformation angeordneten Druckereiprodukten entlang eines ersten Förderweges auf. Zwischen diesem und einem zweiten Förderweg ist ein Uberführförderer vorgesehen, um über die von den Bandförderern gebildete Stufe transportierte Druckereiprodukte einzel- oder sektionsweise aus der Schuppenformation herauszulösen und dem zweiten Förderweg zuzuführen. Der in Förderrichtung gesehen nach der Stufe angeordnete und die aus der Schuppenformation herausgelösten Druckereiprodukte schräg nach oben transportierende Uberführförderer weist einen ortsfesten Führungsteil und einen darin teleskopartig verschiebbaren Schlitten auf. Zwei Förderbänder, deren förderwirksame, aneinanderanliegende und so einen Förderspalt bildende Trume vom am unteren Ende des Schlittens angeordneten Walzen zu am oberen Ende des Führungsteils gelagerten Walzen verlaufen, sind mit ihren Rücktrumen um am unteren Ende des Führungsteils und am oberen Ende des Schlittens vorgesehene weitere Walzen geführt, um die Veränderungen der Länge der förderwirksamen Trume beim Verschieben des Schlittens auszugleichen. Am unteren Ende des Schlittens ist eine gegen die Stufe gerichtete Zunge schwenkbar gelagert. Bei sich in seiner unteren Endlage befindendem Schlitten und nach oben verschwenkter Zunge wird die Schuppenformation unter dem Uberführförderer hindurch entlang des ersten Förderweges gefördert. Beim nach unten Verschwenken der Zunge untergreift diese das über die Stufe geförderte Druckereiprodukt und leitet dieses dem Förderspalt des Uberführförderers zu. Sobald das letzte, dem zweiten Förderweg zuzuführende Druckereiprodukt vom Förderspalt ergriffen ist, wird der Schlitten nach oben zurückgezogen und anschliessend die Zunge gegen oben verschwenkt, um dieses Druckereiprodukt vom nachfolgenden zu trennen. Die Geschwindigkeit der Aufwärtsbewegung des Schlittens ist dabei kleiner als die Umlaufgeschwindigkeit der Förderbänder. Diese Umlaufgeschwindigkeit ist, insbesondere wenn sektionsweise Druckereinprodukte aus der Schuppenformation herauszulösen sind, gleich der Fördergeschwindigkeit des ersten Förderers. Dies hat zur Folge, dass die beiden voneinander zu trennenden Druckereiprodukte etwa mit gleicher Geschwindigkeit gefördert werden, und das vom vorauslaufenden, von den Förderbändern gehaltene Druckereiprodukt untergriffene nachfolgende Druckereiprodukt in Richtung nach oben angehoben und auf Grund der Reibung mitgenommen oder aus seiner Lage gegenüber den andern Druckereiprodukten der Schuppenformation verschoben werden kann.An equivalent but differently designed device is known from DE-A-2 820 957. This points a first conveyor with two vertically staggered belt conveyors for transporting printed products arranged in scale formation along a first conveying path. A transfer conveyor is provided between this and a second conveying path in order to detach printed products transported individually or in sections from the scale formation and to feed them to the second conveying path via the step formed by the belt conveyors. The transfer conveyor, which is arranged after the step in the conveying direction and transports the printed products out of the scale formation at an angle upwards, has a stationary guide part and a slide which is telescopically displaceable therein. Two conveyor belts, the conveying, adjoining and thus forming a conveyor gap run from the rollers arranged at the lower end of the carriage to rollers mounted at the upper end of the guide part, are with their back strands around further rollers provided at the lower end of the guide part and at the upper end of the carriage led to compensate for the changes in the length of the conveyor dreams when moving the carriage. At the lower end of the slide, a tongue directed against the step is pivotally mounted. With the sled in its lower end position and the tongue pivoted upwards, the scale formation is conveyed under the transfer conveyor along the first conveying path. When the tongue is pivoted downwards, it engages under the printed product conveyed over the step and directs it to the conveying gap of the transfer conveyor. As soon as the last printed product to be fed into the second conveying path has been gripped by the conveying gap, the carriage is withdrawn upwards and then the tongue is pivoted upwards to separate this printed product from the next one. The speed of the upward movement of the carriage is lower than the rotational speed of the conveyor belts. This rotational speed is equal to the conveying speed of the first conveyor, in particular if section-by-product printer products are to be extracted from the scale formation. This has the consequence that the two printed products to be separated from each other are conveyed at approximately the same speed, and the subsequent printed product, which is under attack by the leading printed product held by the conveyor belts, is lifted upwards and carried along due to the friction or from its position in relation to the others Printed products of the scale formation can be moved.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, eine gattungsgemässe Vorrichtung derart weiterzubilden, dass die gegenseitige Lage der dem zweiten Förderweg zuzuführenden Erzeugnisse unabhängig von der Lage des Uberführförderers erhalten bleibt.It is therefore an object of the present invention to develop a generic device in such a way that the mutual position of the products to be fed to the second conveying path is retained regardless of the position of the transfer conveyor.

Diese Aufgabe wird durch eine gattungsgemässe Vorrichtung, die die Merkmale des kennzeichnenden Teiles des Anspruchs 1 aufweist, gelöst.This object is achieved by a generic device which has the features of the characterizing part of claim 1.

Oberhalb des ersten Förderers 12 ist ein ebenfalls als Bandförderer ausgebildeter, einen zweiten Förderweg 17 festlegender zweiter Förderer 18 vorgesehen, dessen Anfang 18' in Förderrichtung F gesehen, zwischen dem Anfang 12' und Ende 12'' des ersten Förderers 12 liegt und dessen Ende nicht gezeigt ist. Zwischen dem ersten Förderer 12 und dem zweiten Förderer 18 ist ein Uberführförderer 20 vorgesehen, welcher ebenfalls als Bandförderer ausgebildet ist und zwei hintereinandergeschaltete, schwenkbar miteinander verbundene Förderarme 22 und 24 aufweist. Der ortsfeste Förderausgang 20' des Uberführförderers 20 ist dem Anfang 18' des zweiten Förderers 18 unmittelbar vorgelagert und der Fördereingang 26 ist mittels einer am zweiten Förderarm 24 angreifenden Antriebsanordnung 28 durch knieartiges Verschwenken der beiden Förderarme 22 und 24 von der, in der Figur 1 mit ausgezogenen Linien gezeigten Arbeitslage, in eine strichpunktiert angedeutete Rückzuglage 26' und wieder zurück verbringbar. Bei sich in Rückzugslage 26' befindendem Fördereingang 26 werden Druckereiprodukte 30, wie Zeitungen, Zeitschriften und dergleichen, in Schuppenformation S (siehe Figuren 3 - 7) entlang dem ersten Förderweg 16 in Förderrichtung F transportiert. Zum Umleiten von Druckereiprodukten 30 vom ersten Förderweg 16 auf den zweiten Förderweg 17 wird der Fördereingang 26 des Uberführförderers 20 in die vom oberen Trum 14 des ersten Förderers 12 gebildete Stufe 32 benachbart nachgeschaltete Arbeitslage verbracht, sodass die in Förderrichtung F gesehen vorlaufenden Kanten 30' der über die Stufe 32 geförderten Druckereiprodukte 30 in den Fördereingang 26 einlaufen und entlang der Förderstrecke 34 des Uberführförderers 20 zum Förderausgang 20' und dem zweiten Förderer 18 zugeführt werden. Dabei ist zu beachten, dass die Förderstrecke 34 unabhängig von der Lage der beiden Förderarme 22 und 24 im wesentlichen konstant ist. Sobald die gewünschte Anzahl auf den zweiten Förderweg 17 umzuleitenden Druckereiprodukte 30 in den Fördereingang 26 eingelaufen sind, wird der Fördereingang 26 durch gleichzeitiges Verschwenken der beiden Förderarme 22, 24 mittels der Antriebsanordnung 28 in die Rückzugslage 26' zurückverbracht, wobei das letzte vom Fördereingang 26 erfasste Druckereiprodukt 30 unter dem nachfolgenden Druckereiprodukt 30 weggezogen wird. Das letztgenannte und alle nachfolgenden Druckereiprodukte 30 werden dann wieder entlang dem ersten Förderweg 16 weitergefördert.The switch-like conveyor device 10 shown in FIGS. 1 and 2 has a first conveyor 12 designed as a belt conveyor, the upper run 14 of which runs along a first conveyor path 16. The conveying direction of the first conveyor 12 is indicated by F. Above the first conveyor 12 there is a second conveyor 18, which is also designed as a belt conveyor and defines a second conveying path 17, the beginning 18 'of which, seen in the conveying direction F, lies between the beginning 12' and the end 12 '' of the first conveyor 12 and the end of which is not is shown. A transfer conveyor 20 is provided between the first conveyor 12 and the second conveyor 18, which is also designed as a belt conveyor and has two conveyor arms 22 and 24 connected in series and pivotally connected to one another. The stationary conveyor output 20 'of the transfer conveyor 20 is immediately upstream of the beginning 18' of the second conveyor 18 and the conveyor input 26 is by means of a drive arrangement 28 acting on the second conveyor arm 24 by pivoting the two conveyor arms 22 and 24 like a knee from the one shown in FIG Solid lines shown working position, in a retracted position 26 'indicated by dash-dotted lines and can be brought back again. When the feed inlet 26 is in the retracted position 26 ', printed products 30, such as newspapers, magazines and the like, become in a scale formation S (see FIGS. 3-7) transported along the first conveying path 16 in the conveying direction F. In order to redirect printed products 30 from the first conveyor path 16 to the second conveyor path 17, the conveyor inlet 26 of the transfer conveyor 20 is moved into the adjacent working position 32 formed by the upper run 14 of the first conveyor 12, so that the edges 30 ′ leading in the conveying direction F are moved Via the stage 32 conveyed printed products 30 enter the conveying inlet 26 and are fed along the conveying path 34 of the transfer conveyor 20 to the conveying outlet 20 'and the second conveyor 18. It should be noted that the conveyor section 34 is essentially constant regardless of the position of the two conveyor arms 22 and 24. As soon as the desired number of printed products 30 to be redirected to the second conveying path 17 has entered the conveying inlet 26, the conveying inlet 26 is brought back into the retracted position 26 'by simultaneously pivoting the two conveying arms 22, 24 by means of the drive arrangement 28, the last being detected by the conveying inlet 26 Printed product 30 is pulled away under the subsequent printed product 30. The latter and all subsequent printed products 30 are then conveyed again along the first conveying path 16.

Der erste Förderarm 22 ist im Bereich seines förderwirksamen Endes 22' ortsfest gelagert. Zu diesem Zweck ist eine Welle 38 an, von einem Gestell 40 des ersten Förderers 12 gegen oben abstehenden Tragplatten 42, von welchen in der Figur 1 nur eine gezeigt ist, ortsfest drehbar gelagert. An dieser Welle 38 sind zwei parallel zueinander verlaufende und in Richtung der Welle 38 voneinander beabstandete Lagerschilder 44 einerends schwenkbar angeordnet, an deren anderem Ende die Lagerschilder 44' des zweiten Förderarms 24 schwenkbar abgestützt sind. Zu diesem Zweck sind die beiden Lagerschilder 44 in ihrem freien Endbereich mittels einer Lagerwelle 46 miteinander verbunden, auf welcher die Lagerschilder 44' mit ihren diesseitigen Endbereichen schwenkbar sitzen. Auf der Lagerwelle 46 sitzt weiter frei drehbar zwischen den Lagerschildern 44, 44' eine Umlenkwalze 48. Um diese ist der obere, förderwirksame Trum 50 eines beiden Förderarmen 22 und 24 gemeinsamen Förderbandes 50' geführt, welches eine am freien Ende der Lagerschilder 44' frei drehbar gelagerte Walze 54 und eine auf der Welle 38 sitzende angetriebene Walze 54' umgreift. Der förderwirksame Trum 50 ist von, nur in der Figur 1 angedeuteten, zwischen diesen Walzen 54, 54' und der Umlenkwalze 48 vorgesehenen und ebenfalls an den Lagerschildern 44, 44' gelagerten Stützwalzen 56 getragen. Je eine weitere Stützwalze 56' ist an jedem Lagerschildpaar 44, 44' benachbart zur Umlenkwalze 48 vorgesehen, über welche der Rücktrum 50'' des Förderbandes 50' geführt ist, um diesen an der Umlenkwalze 48 in Anlage zu halten.The first conveyor arm 22 is mounted in a stationary manner in the region of its end 22 'which is effective for conveying. For this purpose, a shaft 38 is mounted on a frame 40 of the first conveyor 12 against supporting plates 42 protruding upwards, only one of which is shown in FIG. On this shaft 38 are two mutually parallel and spaced apart in the direction of the shaft 38 End shields 44 are pivotally arranged at one end, at the other end of which the end shields 44 'of the second conveyor arm 24 are pivotally supported. For this purpose, the two end shields 44 are connected to one another in their free end region by means of a bearing shaft 46, on which the end shields 44 ′ are pivotably seated with their end regions on this side. On the bearing shaft 46, a deflecting roller 48 is seated freely rotatable between the bearing plates 44, 44 '. Around this, the upper, conveyor-effective section 50 of a conveyor belt 50' common to both conveyor arms 22 and 24 is guided, which one is free at the free end of the bearing plates 44 ' rotatably mounted roller 54 and a driven roller 54 'seated on the shaft 38. The conveyor-effective strand 50 is carried by support rollers 56, only indicated in FIG. 1, provided between these rollers 54, 54 'and the deflection roller 48 and also supported on the end shields 44, 44'. A further support roller 56 'is provided on each pair of end shields 44, 44' adjacent to the deflection roller 48, over which the rear run 50 '' of the conveyor belt 50 'is guided in order to hold it against the deflection roller 48.

Die Antriebsanordnung 28 weist einen am Gestell 40 ortsfest schwenkbar gelagerten Antriebshebel 58 auf, welcher andernends mit dem, in Förderrichtung F gesehen rechten Lagerschild 44' des zweiten Förderarms 24 in dessen Mittelbereich schwenkbar verbunden ist. Am Antriebshebel 58 greift ungefähr mittig die Kolbenstange 60 eines Kolben-Zylinderaggregates 60' an, welches andernends ebenfalls am Gestell 40 abgestützt ist. Bei in das Kolben-Zylinderaggregat 60' eingefahrener Kolbenstange 60 befinden sich die beiden Förderarme 22, 24 in einer nahezu gestreckten Lage, welche der Arbeitslage des Fördereingangs 26 entspricht. Durch Ausfahren der Kolbenstange 60 aus dem Kolben-Zylinderaggregat 60' wird der Antriebshebel 58 in die strichpunktiert gezeigte Lage (Figur 1) verschwenkt, wodurch die beiden Förderarme 22, 24 gemeinsam kniehebelartig gegeneinander verschwenkt werden, um den Fördereingang 26 in die Rückzugslage 26' zu verbringen.The drive arrangement 28 has a drive lever 58 which is mounted on the frame 40 so that it can be pivoted in a fixed manner and which is at the other end pivotably connected to the right end plate 44 'of the second conveyor arm 24 in the central region thereof, as seen in the conveying direction F. The piston rod 60 of a piston-cylinder unit 60 ′, which is also supported on the frame 40 at the other end, acts approximately centrally on the drive lever 58. When the piston rod 60 is retracted into the piston-cylinder unit 60 ', the two conveyor arms 22, 24 are in an almost extended state Location which corresponds to the working situation of the funding entrance 26. By moving the piston rod 60 out of the piston-cylinder unit 60 ', the drive lever 58 is pivoted into the position shown in dash-dot lines (FIG. 1), as a result of which the two conveyor arms 22, 24 are jointly pivoted relative to one another in a toggle-lever manner in order to feed the conveyor 26 into the retracted position 26' spend.

Wie dies insbesondere aus der Figur 2 hervorgeht, ist der Uberführförderer 20 in Richtung rechtwinklig zur Förderrichtung F schmaler ausgebildet als der erste und zweite Förderer 12, 16. Um die entlang dem ersten Förderweg 16 zu transportierenden Druckereiprodukte 30 nicht zu behindern, steht vom in Förderrichtung F gesehen rechten Lagerschild 44' ein Tragarm 62 ab, an welchem der ausserhalb des Förderbereichs des ersten Förderers 12 verlaufende Antriebshebel 58 angreift.As can be seen in particular from FIG. 2, the transfer conveyor 20 is made narrower in the direction perpendicular to the conveying direction F than the first and second conveyors 12, 16. In order not to impede the printed products 30 to be transported along the first conveying path 16, the stands in the conveying direction F seen on the right end shield 44 ', a support arm 62, on which the drive lever 58 extending outside the conveying area of the first conveyor 12 engages.

Um die, dem zweiten Förderer 18 zuzuführenden Druckereiprodukte 30 unabhängig von der Lage der Förderarme 22 und 24 am förderwirksamen Trum 50 zu halten, ist ein Andrückband 64 vorgesehen, dessen unterer, andrückwirksamer Trum 64' am förderwirksamen Trum 50 anliegt und mit diesem einen Förderspalt 66 bildet. An den Lagerschildern 44 sind benachbart zur Lagerwelle 46 nach aussen abgekröpfte und gegen oben vorstehende Arme 68 angeformt, deren freie Enden durch eine weitere Welle 70, oberhalb des förderwirksamen Trums 50 und andrückwirksamen Trums 64', miteinander verbunden sind. An dieser weiteren Welle 70 sind zwei Laschenpaare 72 schwenkbar gelagert, deren freie Enden je mit lagerschilderartigen Lagergliedern 74 schwenkbar verbunden sind. Diese sind mittels Federanordnungen 80 in Richtung gegen unten und somit gegen die Lagerschilder 44, 44' vorgespannt. An den von den Laschenpaaren 72 abgewandten Enden der Lagerglieder 74 sind, im Bereich des Fördereingangs 26 und Förderausgangs 20', Walzen 82 frei drehbar gelagert, um welche das Andrückband 64 geführt ist. Von diesen verläuft das Andrückband 64 mit seinem Rücktrum 64'' entlang den Lagergliedern 74 zu weiteren Walzen 84, welche bei der Gelenkverbindung zwischen den Lagergliedern 74 und den Laschenpaaren 72 vorgesehen sind und um diese herum zu einer, an der weiteren Welle 70 frei drehbar gelagerten Walze 84'.In order to hold the printed products 30 to be fed to the second conveyor 18 irrespective of the position of the conveyor arms 22 and 24 on the conveyor-effective strand 50, a pressure belt 64 is provided, the lower, pressing-on strand 64 'of which rests on the conveyor-effective strand 50 and with this a conveyor gap 66 forms. On the end shields 44 adjacent to the bearing shaft 46 are bent outwardly and protruding arms 68, the free ends of which are connected to each other by a further shaft 70, above the conveying section 50 and pressing section 64 '. On this further shaft 70 two pairs of tabs 72 are pivotally mounted, the free ends of which are each pivotally connected to bearing plate-like bearing members 74. These are by means of spring arrangements 80 in Direction biased towards the bottom and thus against the end shields 44, 44 '. At the ends of the bearing members 74 facing away from the plate pairs 72, in the region of the conveyor inlet 26 and conveyor outlet 20 ', rollers 82 are freely rotatably supported, around which the pressure belt 64 is guided. From these, the pressure belt 64 runs with its rear run 64 ″ along the bearing members 74 to further rollers 84, which are provided in the articulated connection between the bearing members 74 and the pairs of tabs 72 and around them to form a freely rotatably mounted on the further shaft 70 Roller 84 '.

Die im Mittelbereich der Lagerschilder 44, 44' und beidseits vorgesehenen Federanordnungen 80 weisen je eine Druckfeder 86 auf, deren unteres Ende sich an einem von den Lagergliedern 74 nach aussen abstehenden Träger 88 und oberes Ende an einem Zugstab 90 abstützt, welcher durch die Druckfeder 86 und den Träger 88 hindurch verläuft und mit seinem unteren Ende an einem, vom entsprechenden Lagerschild 44, 44' in Richtung gegen aussen abstehenden weiteren Träger 92 befestigt ist. Die Zugstäbe 90 sind bezüglich den ihnen zugeordneten Lagerschildern 44, 44' fest angeordnet, wodurch die Lage der Lagerglieder 74, in Längsrichtung der Lagerschilder 44, 44' gesehen, festgelegt ist. Beim gegenseitigen Verschwenken der Förderarme 22 und 24 verschwenken sich somit die Laschenpaare 72 gegeneinander um die Welle 70, so dass die Länge des endlosen Andrückbandes 64 unabhängig von der Lage der Förderarme 22, 24 konstant bleibt.The spring arrangements 80 provided in the middle area of the end shields 44, 44 'and on both sides each have a compression spring 86, the lower end of which is supported on a support 88 projecting outwards from the bearing members 74 and the upper end is supported on a tension rod 90 which is supported by the compression spring 86 and the carrier 88 runs through and is fastened with its lower end to a further carrier 92 protruding outwards from the corresponding end shield 44, 44 '. The tension rods 90 are fixedly arranged with respect to the bearing plates 44, 44 'assigned to them, as a result of which the position of the bearing members 74, viewed in the longitudinal direction of the bearing plates 44, 44', is fixed. When the conveyor arms 22 and 24 are pivoted relative to one another, the pairs of tabs 72 thus pivot relative to one another about the shaft 70, so that the length of the endless pressure belt 64 remains constant regardless of the position of the conveyor arms 22, 24.

Der förderaktive obere Trum 14 des als Bandförderer ausgebildeten ersten Förderers 12 verläuft von einer, am Anfang 12' in bekannter Art und Weise am Gestell 40 frei drehbar gelagerten Umlenkwalze 94, in Förderrichtung F gesehen leicht ansteigend zu einer Stufenwalze 96 und von dieser in entgegengesetzter Richtung zu einer Umlenkrolle 98 und um diese umgelenkt unterhalb der Stufenwalze 96 hindurch zu einer weiteren Umlenkwalze 94' am Ende 12'' des ersten Förderers 12.The conveyor-active upper run 14 of the first conveyor 12, which is designed as a belt conveyor, runs in the direction of conveyance F from a deflection roller 94 which is freely rotatably mounted on the frame 40 at the beginning 12 'in a known manner slightly ascending to a step roller 96 and from there in the opposite direction to a deflection roller 98 and deflected around it below the step roller 96 to a further deflection roller 94 'at the end 12''of the first conveyor 12.

Der, in Förderrichtung F gesehen fallenden Stufe 32 vorgeschaltet, zwischen der Stufenwalze 96 und Umlenkwalze 94, ist eine Zurückhalteeinrichtung 100 vorgesehen, die ein mit dem oberen Trum 14 zusammenwirkendes endloses Anpressband 102 aufweist. Vom Gestell 40 steht in vertikaler Richtung ein Tragarm 106 ab, an dessen oberen Ende ein Gewichtsarm 108 gelagert ist, an dessen freien Ende schildartige Lagerlaschen 110 ungefähr mittig gelagert sind. An den beiden Enden der Lagerlaschen 110 sind Umlenkrollen 112 gelagert, um welche das Anpressband 102 geführt ist. Der untere, dem oberen Trum 14 des ersten Förderers 12 zugewandte Trum des Anpressbandes 102, bildet mit jenem zusammen einen Förderspalt für die Druckereiprodukte 30, um das jeweils vom Uberführförderer 20 nicht erfasste Druckereiprodukt 30 beim Zurückverschwenken des Fördereingangs 26 von der Arbeitslage in die Rückzugslage 26' am Mitnehmen zu hindern.Upstream of the step 32 falling in the conveying direction F, between the step roller 96 and the deflecting roller 94, a restraint device 100 is provided which has an endless pressure belt 102 which interacts with the upper run 14. A support arm 106 protrudes from the frame 40 in the vertical direction, at its upper end a weight arm 108 is mounted, at the free end of which plate-like bearing brackets 110 are mounted approximately centrally. Deflection rollers 112, around which the pressure belt 102 is guided, are supported at the two ends of the bearing brackets 110. The lower strand of the pressure belt 102 facing the upper strand 14 of the first conveyor 12, together with the latter, forms a conveying gap for the printed products 30, around the printed product 30, which is not covered by the transfer conveyor 20 when the conveying input 26 is pivoted back from the working position into the retracted position 26 '' to prevent taking away.

Am Gestell ist weiter ein Antriebsmotor 114 angeordnet, der über einen ersten, strichpunktiert angedeuteten Kettentrieb 116 zum Antreiben des Förderbandes des ersten Förderers 12 mit der Umlenkwalze 94' und zum Antreiben des Förderbandes 50' des Uberführföderers 20 mit der Walze 54' verbunden ist. Ein weiterer mit dem Antriebsmotor 114 verbundener Kettentrieb 118 treibt über mehrere, diesem nachgeschaltete, ebenfalls strichpunktiert angedeutete Kettentriebe 118' das Anpressband 102 an. Im weitern ist der zweite Förderer 18 über einen, ebenfalls nur strichpunktiert angedeuteten Kettentrieb 120 in bekannter Art und Weise über die Welle 38 und den Kettentrieb 116 vom Antriebsmotor 114 angetrieben. Die vom Förderband 50' umschlungene und durch dieses angetriebene Umlenkwalze 48 ist über einen weiteren, ebenfalls nur strichpunktiert angedeuteten Kettentrieb 122 mit der Walze 84' gekoppelt um das Andrückband 64 synchron mit dem Förderband 50' anzutreiben. Sämtliche Förder-, Andrück- und Anpressbänder der Fördereinrichtung 10 sind mit derselben Fördergeschwindigkeit v umlaufend angetrieben.A drive motor 114 is also arranged on the frame, which is connected via a first chain drive 116, indicated by dash-dotted lines, for driving the conveyor belt of the first conveyor 12 with the deflection roller 94 'and for driving the conveyor belt 50' of the transfer conveyor 20 with the roller 54 '. Another chain drive 118 connected to the drive motor 114 drives via a plurality of chain drives connected downstream thereof and also indicated by dash-dotted lines 118 'to the pressure belt 102. Furthermore, the second conveyor 18 is driven by the drive motor 114 in a known manner via the chain 38 and the chain drive 116 via a chain drive 120, which is also only indicated by dash-dotted lines. The deflecting roller 48, which is wrapped around by the conveyor belt 50 'and driven by it, is coupled to the roller 84' via a further chain drive 122, likewise indicated only by dash-dotted lines, in order to drive the pressure belt 64 synchronously with the conveyor belt 50 '. All conveyor, pressure and pressure belts of the conveyor 10 are driven in rotation at the same conveyor speed v.

Dem ersten Förderer 12 ist ein ebenfalls als Bandförderer ausgebildeter Zuförderer 124 vorgeschaltet, um die in Schuppenformation S angeordneten Druckereiprodukte 30 dem ersten Förderer 12 zuzuführen. Im weitern ist dem ersten Förderer 12 ein ebenfalls als Bandförderer ausgebildeter Wegförderer 126 nachgeschaltet, um die vom ersten Förderer 12 transportierten und nicht dem zweiten Förderer 18 zugeführten Druckereiprodukte 30 einer nicht gezeigten Verarbeitungsstation zuzuführen. Im Bereich des Zuförderers 124 ist eine allgemein bekannte Zähleinrichtung 128 vorgesehen, um die dem ersten Förderer 12 zugeführten Druckereiprodukte 30 zu zählen.The first conveyor 12 is preceded by a feed conveyor 124, which is also designed as a belt conveyor, in order to feed the printed products 30 arranged in scale formation S to the first conveyor 12. Furthermore, the first conveyor 12 is followed by a conveyor 126, which is also designed as a belt conveyor, in order to feed the printed products 30 transported by the first conveyor 12 and not supplied to the second conveyor 18 to a processing station (not shown). A generally known counting device 128 is provided in the area of the feed conveyor 124 in order to count the printed products 30 fed to the first conveyor 12.

Der Vollständigkeit halber sei noch erwähnt, dass der zweite Förderarm 24 eine in Richtung gegen die Stufe 32 vorstehende Zunge 130 aufweist, um beim Verbringen des Fördereingangs 26 in die Arbeitslage die vorlaufende Kante 30' des vom Uberführförderer 20 zu erfassenden Druckereiproduktes 30 zu untergreifen.For the sake of completeness, it should also be mentioned that the second conveyor arm 24 has a tongue 130 protruding in the direction of the step 32 in order to engage under the leading edge 30 'of the printed product 30 to be gripped by the transfer conveyor 20 when the conveyor inlet 26 is brought into the working position.

Die Funktionsweise der in den Figuren 1 und 2 gezeigten Fördereinrichtung 10 wird nun anhand der Figuren 3 - 7 erläutert. In diesen Figuren ist der Bereich der Stufe 32 des ersten Förderers 12 und der Bereich des Fördereingangs 26 des Uberführförderers 20 vergrössert dargestellt. Gleiche Teile wie in den Figuren 1 - 2 sind in diesen Figuren 3 - 7 mit gleichen Bezugszeichen versehen.The operation of the conveyor 10 shown in Figures 1 and 2 will now be explained with reference to Figures 3-7. In these figures, the area of the step 32 of the first conveyor 12 and the area of the feed entrance 26 of the transfer conveyor 20 are shown enlarged. The same parts as in FIGS. 1-2 are provided with the same reference numerals in these FIGS. 3-7.

Gemäss Figur 3 werden die in Schuppenformation S zugeführten Druckereiprodukte 30 auf dem oberen Trum 14 des ersten Förderers 12 aufliegend über die Stufe 32 entlang dem ersten Förderweg 16 dem Wegförderer 126 zugeführt (vergleiche auch Figur 1). Der Fördereingang 26 des Uberführförderers 20 befindet sich in einer Wartelage 26'' in der Nähe der Stufe 32. Diese Wartelage 26'' wird dadurch erzielt, dass das Kolben-Zylinderaggregat 60' den Antriebshebel 58 in eine Zwischenstellung zwischen den beiden in der Figur 1 gezeigten Endstellungen verschwenkt. In dieser Wartelage 26'' befindet sich der Fördereingang 26 soweit von der Stufe 32 entfernt, dass die infolge der Eigensteifigkeit der Druckereiprodukte 30 über die Stufe 32 frei vorstehenden vorlaufenden Bereiche mit der vorlaufenden Kante 30' nicht in den Fördereingang 26 gelangen, sondern unter diesem hindurch, entlang dem ersten Förderweg 16, weitergefördert werden. Es ist aber zu beachten, dass bei der Stufe 32 der vorlaufende Bereich jedes Druckereiproduktes 30 vom vorauslaufenden Druckereiprodukt 30 für eine bestimmte Zeit abgehoben ist.According to FIG. 3, the printed products 30 fed in scale formation S, lying on the upper run 14 of the first conveyor 12, are fed to the conveyor 126 via the stage 32 along the first conveyor path 16 (see also FIG. 1). The conveying inlet 26 of the transfer conveyor 20 is in a waiting position 26 ″ in the vicinity of the stage 32. This waiting position 26 ″ is achieved in that the piston-cylinder unit 60 ′ moves the drive lever 58 into an intermediate position between the two in FIG. 1 shown end positions pivoted. In this waiting position 26 ″, the conveyor inlet 26 is so far away from the stage 32 that the leading areas with the leading edge 30 ′, which protrude freely over the stage 32 due to the inherent rigidity of the printed products 30, do not reach the conveyor inlet 26, but under it through, along the first conveying path 16. It should be noted, however, that at stage 32 the leading area of each printed product 30 is lifted off from the leading printed product 30 for a certain time.

Sobald nun Druckereiprodukte 30 dem den zweiten Förderweg 17 definierenden Förderer 18 zuzuführen sind, wird der Fördereingang 26 in die in der Figur 4 gezeigte Arbeitslage verbracht. Dies geschieht durch komplettes Einfahren der Kolbenstange 60. Das in diesem Moment über die Stufe 32 geförderte Druckereiprodukt 30 gelangt in den Fördereingang 26, wobei die Zunge 130 zwischen dieses Druckereiprodukt 30 und das vorauslaufende Druckereiprodukt 30 einsticht. Da die Fördergeschwindigkeit v des Uberführförderers 20 genau gleich gross ist wie die Fördergeschwindigkeit v des ersten Förderers 12 wird die Schuppenformation S beim Zuführen zum zweiten Förderer 18 beibehalten, wie dies Figur 5 zeigt, und die der Stufe 32 folgend auf dem oberen Trum 14 aufliegenden Druckereiprodukte 30 werden mit unveränderter Fördergeschwindigkeit v entlang dem ersten Förderweg 16 weitergefördert. Der Uberführförderer 20 bleibt nun solang in dieser Stellung, als Druckereiprodukte 30 dem zweiten Förderweg 17 zuzuführen sind (vergleiche auch Figur 1).As soon as printed products 30 are to be fed to the conveyor 18 defining the second conveying path 17, the conveying inlet 26 becomes the working position shown in FIG spent. This is done by completely retracting the piston rod 60. The printed product 30, which is being conveyed via the stage 32 at this moment, reaches the feed inlet 26, the tongue 130 sticking between this printed product 30 and the preceding printed product 30. Since the conveying speed v of the transfer conveyor 20 is exactly the same as the conveying speed v of the first conveyor 12, the scale formation S is maintained when it is fed to the second conveyor 18, as shown in FIG. 5, and the printed products following the step 32 on the upper run 14 30 are conveyed along unchanged conveying speed v along the first conveying path 16. The transfer conveyor 20 now remains in this position for as long as printed products 30 are to be fed to the second conveying path 17 (see also FIG. 1).

Die zugeführten Druckereiprodukte 30 werden mittels der Zähleinrichtung 128 gezählt (Figur 1). Aufgrund der Kenntnis der Fördergeschwindigkeit v kann nun nach einer genau vorgegebenen Anzahl Druckereiprodukte 30 der Fördereingang 26 aus seiner Arbeitslage weggezogen werden, um die Zuführung zum zweiten Förderweg 17 nach der genau vorgegebenen Anzahl Druckereiprodukte 30 zu unterbrechen. Beim Verschieben des Fördereingangs 26 von der Arbeitslage in die Rückzugslage 26', was durch Ausfahren der Kolbenstange 60 des Kolben-Zylinderaggregates 60' geschieht, wird der Fördereingang 26 mit einer Geschwindigkeit v₁ von der Stufe 32 nach schräg oben wegbewegt, welche grösser ist, als die Fördergeschwindigkeit v der zugeführten Druckereiprodukte 30. Dadurch wird das vom Fördereingang 26 zuletzt erfasste Druckereiprodukt 30 unter dem nachfolgenden Druckereiprodukt 30 weggezogen, wobei die Zurückhalteeinrichtung 100 eine Mitnahme dieses letztgenannten Druckereiproduktes 30 verhindert (siehe Figur 6). Im weitern wird durch diese hohe Geschwindigkeit v₁ des Zurückziehens des Fördereinganges 26 mit Sicherheit vermieden, dass das erste wieder dem Wegförderer 126 zuzuführende Druckereiprodukt 30 in den Fördereingang 26 gelangen kann.The printed products 30 supplied are counted by means of the counter 128 (FIG. 1). Based on the knowledge of the conveying speed v, the conveying inlet 26 can now be pulled out of its working position after a precisely predefined number of printed products 30 in order to interrupt the supply to the second conveying path 17 after the precisely predefined number of printed products 30. When moving the feed input 26 from the working position to the retracted position 26 ', which is done by extending the piston rod 60 of the piston-cylinder unit 60', the feed input 26 is moved away at a speed v 1 from the stage 32 upwards, which is greater than the conveying speed v of the printed products 30 supplied. As a result, the last printed product 30 detected by the conveying input 26 becomes the following one Printed product 30 pulled away, with the retaining device 100 preventing the latter printed product 30 from being carried along (see FIG. 6). Furthermore, this high speed v 1 of retracting the conveying input 26 prevents with certainty that the first printed product 30 to be fed back to the conveyor 126 can get into the conveying input 26.

Wie dies Figur 7 zeigt, werden nun die nachfolgend zugeführten Druckereiprodukte 30 wieder entlang dem ersten Förderweg 16 dem Wegförderer 126 zugeführt und die im Förderspalt 66 des Uberführförderers 20 gehaltenen Druckereiprodukte 30 werden mit unveränderter Geschwindigkeit v und unveränderten Abständen zum zweiten Förderer 18 gefördert. Der Fördereingang 26 kann nun in seiner Rückzugslage 26' verbleiben oder falls weitere Druckereiprodukte 30 auf den zweiten Förderweg 17 umzulenken sind, wieder in die in der Figur 3 gezeigte Wartelage 26'' verbracht werden.As shown in FIG. 7, the subsequently supplied printing products 30 are again fed along the first conveying path 16 to the removal conveyor 126 and the printing products 30 held in the conveying gap 66 of the transfer conveyor 20 are conveyed to the second conveyor 18 at unchanged speed v and unchanged distances. The conveying inlet 26 can now remain in its retracted position 26 'or, if further printed products 30 are to be redirected to the second conveying path 17, can be brought back into the waiting position 26' 'shown in FIG.

Es ist zu beachten, dass die Fördergeschwindigkeit v der Druckereiprodukte 30 unabhängig von der Lage des Uberführförderers 20 immer konstant sein kann. Es ist nicht nötig, die Fördergeschwindigkeit v des Uberführförderers 20 und des zweiten Förderers 18 zu erhöhen, um ein Trennen aufeinanderfolgender Druckereiprodukte bei der Stufe 32 zu erzielen. Im weitern bleibt die Förderstrecke 34 zwischen dem Fördereingang 26 und dem Förderausgang 20' unabhängig von der gegenseitigen Lage der beiden Förderarme 22, 24 ungefähr gleich, so dass die Schuppenformation der Druckereiprodukte 30 auch während dem Bewegen des Uberführförderers 20 erhalten bleibt. Da die Umschlingung der Umlenkwalze 48 beim Verkleinern des Winkels zwischen den beiden Förderarmen 22 und 24 zunimmt und die Walze 54' am Förderausgang 20' des Uberführförderers 20 mit konstanter Umlaufgeschwindigkeit angetrieben ist, wird somit die Geschwindigkeit des förderwirksamen Trums 50 im Bereich zwischen dem Fördereingang 26 und der Umlenkwalze 48 beim Verbringen des Fördereingangs 26 in die Rückzugslage 26' geringfügig vergrössert, was die Trennung der aufeinanderfolgenen Druckereiprodukte 30 bei der Stufe 32 unter Beibehaltung der Schuppenformation S im Bereich des Uberführförderers 20 zusätzlich unterstützt.It should be noted that the conveying speed v of the printed products 30 can always be constant regardless of the position of the transfer conveyor 20. It is not necessary to increase the conveying speed v of the transfer conveyor 20 and the second conveyor 18 in order to achieve a separation of successive printed products at the stage 32. Furthermore, the conveying path 34 between the conveying inlet 26 and the conveying outlet 20 'remains approximately the same regardless of the mutual position of the two conveying arms 22, 24, so that the scale formation of the printed products 30 is maintained even during the movement of the transfer conveyor 20. Since the looping of the deflecting roller 48 when the angle between the increases both conveyor arms 22 and 24 and the roller 54 'at the conveyor output 20' of the transfer conveyor 20 is driven at a constant circulating speed, the speed of the conveyor-effective strand 50 in the area between the conveyor input 26 and the deflection roller 48 when the conveyor input 26 is brought into the retracted position 26 'is slightly enlarged, which additionally supports the separation of the successive printed products 30 at stage 32 while maintaining the scale formation S in the area of the transfer conveyor 20.

Mit der erfindungsgemässen Einrichtung ist es auch möglich, nur einzelne Druckereiprodukte 30, beispielsweise Makulatur aus der zugeführten Schuppenformation S herauszulösen. Dazu wird der Fördereingang 26 nur für die notwendige Zeit zum Erfassen dieses Druckereiproduktes 30 in seine Arbeitslage verbracht.With the device according to the invention, it is also possible to remove only individual printed products 30, for example waste, from the supplied scale formation S. For this purpose, the conveying input 26 is only brought into its working position for the time required to grasp this printed product 30.

Es ist selbstverständlich auch möglich, den Uberführförderer anders als in den Figuren gezeigt auszubilden; so wäre es denkbar, jeden Förderarm 22, 24 als eigener Bandförderer oder auch die Führung für das Andrückband andersartig auszubilden. Im weitern ist das Vorhandensein einer Stufe nicht zwingend notwendig, kann doch der Uberführförderer mit einer entsprechend ausgebildeten Zunge in die Schuppenformation S einstechen. Gegebenenfalls kann auch auf eine Zurückhalteeinrichtung 100 verzichtet werden.It is of course also possible to design the transfer conveyor differently than shown in the figures; it would be conceivable to design each conveyor arm 22, 24 differently as its own belt conveyor or else as a guide for the pressure belt. Furthermore, the presence of a step is not absolutely necessary, since the transfer conveyor can pierce the scale formation S with a suitably designed tongue. If necessary, a restraint device 100 can also be dispensed with.
