Abstract

The belt conveyor (10) conveys the printed products (12) arranged in an overlapping formation (S) to a transfer region (14). In the overlapping formation (S), each printed product (12) lies on the following one. The dispatch conveyor (18), whose conveying direction (F) in the transfer region (14) runs upwardly, comprises grippers (16) which are fixed so as to be swivellable on a rotationally driven traction element (28). The conveying speeds (v1, v2) of the belt conveyor (10) and dispatch conveyor (18) respectively are geared to one another in such a way that printed products (12) can be fed two at a time into an open gripper (16). The height of the grippers (16) is greater than the spacing (A) separating the leading edges (24) of the printed products (12) in the overlapping formation (S) supplied, so that the two printed products (12) seized by a gripper (16) can be conveyed away with the spacing (A) unaltered. Thus, during the delivery of the printed products (12), it is possible for overlapping formations (S) to be formed in which the printed products (12) essentially re-assume the original spacing (A). <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Wegfördern von Druckereiprodukten, insbesondere mehrblättrigen und vorzugsweise gefalteten Druckereierzeugnissen, die in einer Schuppenformation mit einem bestimmten Abstand hintereinander angeordnet, einander dachziegelartig überlappend zugeführt werden, nach dem Oberbegriff des Anspruches 1 bzw. 4.4. The present invention relates to a method and a device for conveying away printed products, in particular multi-leaf and preferably folded printed products, which are arranged one behind the other in a scale formation and are fed overlapping each other like roof tiles, according to the preamble of claims 1 and 4, respectively.

Eine solche Vorrichtung ist beispielsweise aus der CH-PS 630 583 bzw. der entsprechenden US-PS 4,320,894 bekannt. Ein Zuförderer dieser bekannten Vorrichtung transpor­tiert die Druckereiprodukte in einer Schuppenformation, in welcher jedes Druckereiprodukt auf dem nachfolgenden aufliegt, zu einem Uebernahmebereich. Ein Wegförderer weist an einem umlaufend angetriebenen Zugorgan in einem Abstand hintereinander angeordnete einzeln steuerbare Greifer auf, wobei die Förderrichtung des Wegförderers im Uebernahmebereich quer zur Ebene der zu erfassenden Druckereiprodukte und von deren Unterseite gegen auf­wärts verläuft. Bei dieser bekannten Vorrichtung erfasst jeder Greifer im Uebernahmebereich jeweils ein zugeführ­tes Druckereiprodukt und schält es von der Schuppenfor­mation ab. Durch eine entsprechende Verkleinerung der Fördergeschwindigkeit des Wegförderers im Verhältnis zur Förder Geschwindigkeit des Zuförderers erfassen die Greifer des Wegförderers jeweils zwei Druckereiprodukte und fördern diese gemeinsam weg. Infolge der Verkleine­ rung der Fördergeschwindigkeit des Wegförderers läuft die vorlaufende Kante des jeweils vordersten Druckerei­produktes der zugeführten Schuppenformation auf eine Anschlagschiene auf, wodurch unter Verkleinerung des Schuppenabstandes das nachfolgende Druckereiprodukt wei­ter unter das vorlaufende geschoben wird, bis diese ge­meinsam weggefördert werden.Such a device is known for example from CH-PS 630 583 or the corresponding US-PS 4,320,894. A feed conveyor of this known device transports the printed products in a scale formation, in which each printed product rests on the next one, to a takeover area. A removal conveyor has individually controllable grippers arranged at a distance one behind the other on a rotatingly driven pulling element, the conveying direction of the removal conveyor in the takeover area extending transversely to the plane of the printed products to be detected and from the underside thereof upwards. In this known device, each gripper in the takeover area detects a supplied printed product and peels it off from the scale formation. By appropriately reducing the conveying speed of the conveyer away in relation to the conveying speed of the conveying conveyor, the grippers of the conveying conveyor each grasp two printed products and convey them away together. As a result of the small ones tion of the conveying speed of the conveyor, the leading edge of the foremost printed product of the supplied scale formation runs onto a stop rail, whereby the subsequent printed product is pushed further below the leading end while reducing the scale distance until these are conveyed away together.

Der verkleinerte Schuppenabstand zwischen den beiden je­weils von einem Greifer erfassten Druckereiprodukten eignet sich beispielsweise besonders für eine Weiterver­arbeitung der Druckereiprodukte in einer Vorrichtung, wie sie aus der EP-OS 0 237 701 bzw. der entsprechenden US-PS 4,709,910 bekannt ist. Bei dieser Vorrichtung wer­den mit Hilfe des verkleinerten Schuppenabstandes die freien Enden der beiden von einem Greifer gehaltenen Druckereiprodukte voneinander getrennt und in jeweils verschiedene Taschen einer umlaufenden Trommel einge­führt.The reduced scale distance between the two printed products, each gripped by a gripper, is particularly suitable, for example, for further processing of the printed products in a device such as is known from EP-OS 0 237 701 or the corresponding US Pat. No. 4,709,910. In this device, the free ends of the two printed products held by a gripper are separated from one another with the aid of the reduced scale spacing and inserted into different pockets of a rotating drum.

Wird hingegen für die Weiterverarbeitung der Druckerei­produkte wieder eine Schuppenformation benötigt, in wel­cher die Druckereiprodukte mit ihrem ursprünglichen Ab­stand hintereinander angeordnet sind, so muss der be­kannten Vorrichtung zum Wegfördern von Druckereiproduk­ten eine Vorrichtung nachgeschaltet werden, die den ver­kleinerten Schuppenabstand zwischen den jeweils zwei von einem Greifer erfassten Druckereiprodukten wieder ver­grössert. Dies führt zu einem erheblichen zusätzlichen Aufwand.If, on the other hand, a shingled formation is again required for the further processing of the printed products, in which the printed products are arranged one behind the other with their original spacing, the known device for conveying away printed products must be followed by a device which detects the reduced scale distance between the two in each case by a gripper Printed products enlarged again. This leads to a considerable additional effort.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Wegfördern von Druckereiprodukten, insbesondere mehrblättrigen und vor­zugsweise gefalteten Druckereierzeugnissen, die in einer Schuppenformation mit einem bestimmten Abstand hinter­einander angeordnet, einander dachziegelartig überlap­pend zugeführt werden, vorzuschlagen, bei dem bzw. mit der unter Ausnützung der Vorteile der kleineren Förder­geschwindigkeit des Wegförderers infolge der Erfassung von jeweils wenigstens zwei Druckereiprodukten für die Weiterverarbeitung der Druckereiprodukte, ohne erneutes Vergleichmässigen des Schuppenabstandes, wieder Schup­penformationen gebildet werden können, in welchen der Abstand zwischen den vorlaufenden Kanten der Druckerei­produkte im wesentlichen dem Schuppenabstand in der zu­geführten Schuppenformation entspricht.It is therefore an object of the present invention to propose a method and a device for conveying away printed products, in particular multi-leaf and preferably folded printed products, which are arranged one behind the other in a scale formation and are fed overlapping each other in a tile-like manner, in which or with Taking advantage of the lower conveying speed of the conveyor due to the detection of at least two printed products for the further processing of the printed products, without again comparing the scale spacing, scale formations can again be formed in which the distance between the leading edges of the printed products essentially corresponds to the scale distance in corresponds to the supplied scale formation.

Diese Aufgabe wird durch die Merkmale des kennzeichnen­den Teiles des Anspruches 1 bzw. 4 gelöst. Es werden je­weils wenigstens zwei Druckereiprodukte, ohne Verkleine­rung des jeweiligen Abstandes den sie in der zugeführten Schuppenformation einnehmen, von einem Greifer des Weg­förderers erfasst und festgehalten. Bei der Abgabe der Druckereiprodukte können somit wieder ohne weitere Ver­fahrensschritte oder zusätzliche Vorrichtungen Schuppen­formationen gebildet werden, in welchen die vorlaufenden Kanten der Druckereiprodukte wieder den ursprünglichen Abstand einnehmen, mit welchem sie zum Uebernahmebereich gefördert wurden.This object is solved by the features of the characterizing part of claims 1 and 4, respectively. At least two printed products are gripped and held in place by a gripper of the conveyor without reducing the respective distance that they occupy in the scale formation supplied. When the printed products are released, scale formations can again be formed without further process steps or additional devices, in which the leading edges of the printed products again assume the original distance with which they were conveyed to the takeover area.

Bei bevorzugten Weiterbildungen des Verfahrens gemäss den Ansprüchen 2 und 3 bzw. bevorzugten Ausbildungsfor­ men der Vorrichtung gemäss den Ansprüchen 6 und 7 werden die erfassten Druckereiprodukte von der zugeführten Schuppenformation nach oben bzw. nach unten abgeschält, so dass der nachfolgende Greifer die nächsten beiden Druckereiprodukte der zugeführten Schuppenformation pro­blemlos im Bereich ihrer vorlaufenden Kanten erfassen und ebenfalls wegfördern kann.In preferred developments of the method according to claims 2 and 3 or preferred training for Men of the device according to claims 6 and 7, the detected printed products are peeled up or down from the supplied scale formation, so that the subsequent gripper can easily grasp the next two printed products of the supplied scale formation in the area of their leading edges and also convey them away.

In einer besonders bevorzugten Ausführungsform weist jeder Greifer zwei Klemmbacken, von welchen eine steu­erbar ist, auf, und das freie Ende der jeweils vorlau­fenden Klemmbacken behält im Uebernahmebereich beim Ein­laufen der Druckereiprodukte zwischen die Klemmbacken seine Lage zur Ebene der zu erfassenden Druckereipro­dukte im wesentlichen unverändert bei. Dadurch wird ein gegenseitiges Verschieben der zu erfassenden Druckerei­produkte beim Einlaufen zwischen die Klemmbacken bzw. beim Schliessen des Greifers verhindert.In a particularly preferred embodiment, each gripper has two clamping jaws, one of which is controllable, and the free end of the leading jaws in each case retains its position in relation to the level of the printed products to be detected when the printed products enter between the clamping jaws. This prevents mutual displacement of the printed products to be detected when they run between the clamping jaws or when the gripper is closed.

Weitere bevorzugte Ausbildungsformen sind in den weite­ren abhängigen Ansprüchen angegeben.Further preferred forms of training are specified in the further dependent claims.

Bei einer Vorrichtung gemäss Anspruch 14 erfasst jeder Greifer des Wegförderers jeweils ein einziges der in Schuppenformation zugeführten Druckereiprodukte, wobei die Vorrichtung und insbesondere die Greifer des Wegför­derers gemäss den Ansprüchen 11 und 12 ausgebildet sind.In a device according to claim 14, each gripper of the removal conveyor detects a single one of the printed products fed in scale formation, the device and in particular the grippers of the removal conveyor being designed according to claims 11 and 12.

Die vorliegende Erfindung wird nun anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. Es zeigen rein schematisch:

  • Fig. 1 und 2 den Uebernahmebereich einer ersten Ausbil­dungsform der Vorrichtung, und
  • Fig. 3 den Uebernahmebereich einer zweiten Aus­führungsform.
The present invention will now be described with reference to two exemplary embodiments shown in the drawing. It shows purely schematically:
  • 1 and 2 the takeover area of a first embodiment of the device, and
  • 3 shows the takeover area of a second embodiment.

Die Figuren 1 und 2 zeigen den Endbereich eines Bandför­derers 10, welcher eine Schuppenformation S von gefalte­ten Druckereiprodukten 12, beispielsweise Zeitungen, Zeitschriften oder Teilen davon, einem Uebernahmebereich 14 zuführt, in welchem jeweils zwei Druckereiprodukte 12 von einem Greifer 16 eines ebenfalls nur teilweise dar­gestellten Wegförderers 18 erfasst und weggefördert wer­den.FIGS. 1 and 2 show the end region of a belt conveyor 10, which feeds a scale formation S of folded printed products 12, for example newspapers, magazines or parts thereof, to a takeover area 14, in each of which two printed products 12 from a gripper 16 of a conveyor which is also only partially shown 18 are recorded and carried away.

Ein Endlosband 20 des Bandförderers 10 ist im Uebernah­mebereich 14 um eine Umlenkwalze 22 geführt und wird mittels eines nicht dargestellten Antriebes in Zuführ­richtung Z umlaufend angetrieben. In der Schuppenforma­tion S liegt jedes Druckereiprodukt 12 auf dem in Zu­führrichtung Z gesehen nachfolgenden Druckereiprodukt 12 auf, und die vorlaufenden Kanten 24 der Druckereiproduk­te 12 sind um den mit einem Doppelpfeil angedeuteten Ab­stand A voneinander beabstandet (Fig. 1). Die Förderge­schwindigkeit des Bandförderers 10 ist mit v₁ bezeich­net.An endless belt 20 of the belt conveyor 10 is guided in the takeover area 14 around a deflecting roller 22 and is driven in a rotating manner in the feed direction Z by means of a drive (not shown). In the scale formation S, each printed product 12 rests on the subsequent printed product 12 seen in the feed direction Z, and the leading edges 24 of the printed products 12 are spaced apart from one another by the distance A indicated by a double arrow (FIG. 1). The conveying speed of the belt conveyor 10 is designated v₁.

Der Wegförderer 18 weist ein in einem Führungskanal 26 geführtes und mit der Fördergeschwindigkeit v₂ umlaufend in Förderrichtung F angetriebenes, strichpunktiert ange­deutetes Zugorgan 28, beispielsweise eine in der DE-OS 26 29 528 bzw. der entsprechenden US-PS 4,294,345 be­ schriebene Kugelgelenk-Gliederkette, auf. Am Zugorgan 28 sind hintereinander angeordnete, voneinander beabstande­te Ausleger 30 befestigt, an welchen je ein Greiferge­häuse 32 eines Greifers 16 um eine in den Figuren 1 und 2 nicht dargestellte senkrecht zur Zeichenebene verlau­fende Achse schwenkbar gelagert ist. Der Mittenabstand von jeweils zwei Greifern 16 ist mit B bezeichnet (Fig. 1). Diese Greifer entsprechen konstruktiv und funktions­mässig weitgehend den in der CH-PS 644 816 bzw. der ent­sprechenden US-PS 4,381,056 beschriebenen Greifern. Da­rum werden hier die Greifer 16 nur soweit beschrieben, als dies für das Verständnis ihrer Funktion notwendig ist.The conveyor 18 has a guided in a guide channel 26 and with the conveying speed v₂ rotating in the conveying direction F, dash-dotted line 28, for example, be in DE-OS 26 29 528 or the corresponding US-PS 4,294,345 be written ball joint link chain, on. Arranged one behind the other and spaced apart cantilevers 30 are fastened, on each of which a gripper housing 32 of a gripper 16 is pivotally mounted about an axis which is not shown in FIGS. 1 and 2 and runs perpendicular to the plane of the drawing. The center distance of two grippers 16 is designated by B (Fig. 1). In terms of construction and function, these grippers largely correspond to the grippers described in CH-PS 644 816 and the corresponding US-PS 4,381,056. For this reason, the grippers 16 are only described here to the extent that this is necessary for understanding their function.

Die vorlaufende Klemmbacke 34 ist als Teil des Greifer­gehäuses 32 ausgebildet, an welchem ebenfalls eine seit­lich vorstehende Schwenkrolle 36 drehbar gelagert ist. Im Greifergehäuse 32 ist weiter eine parallel zur Schwenkachse verlaufende Welle 38 schwenkbar gelagert, an welcher in deren Mittelbereich eine zungenförmige Klemmbacke 40 aus Federstahl befestigt ist. Im Greifer­gehäuse 32 ist eine um die Welle 38 herum verlaufende, in den Figuren nicht dargestellte, Spiralfeder vorgese­hen, die sich einerends am Greifergehäuse 32 und andern­ends an der Welle 38 abstützt. Diese Spiralfeder spannt die Welle 38 und somit die Klemmbacke 40 gegen die Of­fenstellung des Greifers 16 vor. In der Fig. 1 ist der, in Förderrichtung F gesehen, hinterste Greifer 16 in der Offenstellung dargestllt. Der in den Figuren 1 und 2 sichtbare Endbereich der Welle 38 durchdringt das Grei­fergehäuse 32 und steht über dieses vor. Auf ihm sitzt drehfest ein Schliesshebel 42. Der Schliesshebel 42 ist als zweiarmiger Winkelhebel ausgebildet, an dessen gegen die Klemmbacken 34, 40 gerichteten Arm eine Rastnase 44 ausgebildet ist, und an dessen anderen, in Förderrich­tung gesehen, nach hinten und gegen den Führungskanal 26 gerichteten Arm eine Schliessrolle 46 drehbar gelagert ist. Die Rastnase 44 arbeitet mit einer Rastnut 48 zu­sammen, welche an einem, am Greifergehäuse 32 schwenkbar gelagerten und im Uhrzeigersinn vorgespannten Klinkenhe­bel 50 angeordnet ist. Der der Rastnut 48 entfernte End­bereich des Klinkenhebels 50 steht in Richtung gegen den Führungskanal 26 vor und ist inbezug zur Förderrichtung F gegen hinten gebogen. Die Klemmbacken 34, 40 tragen an ihren freien Endbereichen Gummibeläge 52, um Beschädi­gungen an den erfassten Druckereiprodukten 12 zu verhin­dern sowie die Haftreibung zu vergrössern. Die Funk­tionsweise der Greifer 16 wird weiter unten näher be­schrieben.The leading jaw 34 is formed as part of the gripper housing 32, on which a laterally projecting swivel roller 36 is also rotatably mounted. In the gripper housing 32, a shaft 38 extending parallel to the swivel axis is also pivotably mounted, on the central region of which a tongue-shaped clamping jaw 40 made of spring steel is fastened. Provided in the gripper housing 32 is a spiral spring which extends around the shaft 38 and is not shown in the figures and which is supported at one end on the gripper housing 32 and at the other end on the shaft 38. This spiral spring biases the shaft 38 and thus the jaw 40 against the open position of the gripper 16. 1, the rearmost gripper 16, viewed in the conveying direction F, is shown in the open position. The end region of the shaft 38 visible in FIGS. 1 and 2 penetrates the gripper housing 32 and projects beyond it. A locking lever 42 sits on it in a rotationally fixed manner. The locking lever 42 is designed as a two-armed angle lever, on the opposite of which the jaws 34, 40 directed arm a locking lug 44 is formed, and on the other, viewed in the conveying direction, rearward and against the guide channel 26, a locking roller 46 is rotatably mounted. The locking lug 44 works together with a locking groove 48 which is arranged on a pawl lever 50 which is pivotably mounted on the gripper housing 32 and is pretensioned in a clockwise direction. The end region of the pawl lever 50 which is removed from the latching groove 48 projects in the direction toward the guide channel 26 and is bent toward the rear in relation to the conveying direction F. The clamping jaws 34, 40 carry rubber coverings 52 at their free end regions in order to prevent damage to the detected printed products 12 and to increase the static friction. The operation of the grippers 16 is described in more detail below.

Am Führungskanal 26 ist im Uebernahmebereich 14 eine Schwenkkulisse 54 vorgesehen, in welcher die am Grei­fergehäuse 32 gelagerte Schwenkrolle 36 geführt ist. Der Abstand zwischen dem Führungskanal 26 und der Schwenkku­lisse 54 ist, in Förderrichtung F gesehen, bis in den Bereich einer gedachten Verlängerung des förderwirksamen Trums des Bandförderers 10 minimal, nimmt in einem an­schliessenden Bereich zu und ist dann bis zum Ende der Schwenkkulisse 54 wieder konstant. Am Führungskanal 26 ist ebenfalls eine, auf die Schliessrolle 46 einwirkende Schliesskulisse 56 befestigt, welche in Förderrichtung F gesehen bis in jenen Bereich reicht, in welchem die Schwenkkulisse 54 den grössten Abstand zum Führungskanal 26 hat. An ihrem Endbereich weist die Schliesskulisse 56 eine Ablaufkante 58 auf.A swivel link 54 is provided on the guide channel 26 in the take-over area 14, in which the swivel roller 36 mounted on the gripper housing 32 is guided. The distance between the guide channel 26 and the swivel link 54 is minimal, as seen in the conveying direction F, down to the area of an imaginary extension of the conveying strand of the belt conveyor 10, increases in a subsequent area and is then constant again until the end of the swivel link 54. A closing link 56 acting on the closing roller 46 is also fastened to the guide channel 26 and, viewed in the conveying direction F, extends into the area in which the pivot link 54 has the greatest distance from the guide channel 26. At its end region, the closing link 56 has a drain edge 58.

Die beiden, in Förderrichtung F gesehen, vordersten Greifer 16 sind in Schliessstellung dargestellt und hal­ten mit ihren Klemmbacken 34, 40 je zwei Druckereipro­dukte 12 im Bereich deren vorlaufenden Kanten 24. In diesem Zusammenhang ist zu beachten, dass die Tiefe der Greifer 16 im Bereich der Klemmbacken 34, 40 grösser ist als der mit A′ angegebene Abstand zwischen den vorlau­fenden Kanten 24 der beiden von einem Greifer 16 gehal­tenen Druckereiprodukten 12 (Fig. 1). Der Abstand A′ entspricht dem Abstand A zwischen den vorlaufenden Kan­ten 24 der Druckereiprodukte 12 in der zugeführten Schuppenformation S. Der dritte Greifer 16 ist während dem Schliessvorgang dargestellt, und der in der Fig. 1 dargestellte vierte Greifer 16 befindet sich in Offen­stellung.The two foremost grippers 16, viewed in the direction of conveyance F, are shown in the closed position and hold with their clamping jaws 34, 40 two printed products 12 in the area of their leading edges 24. In this connection it should be noted that the depth of the grippers 16 in the area of Clamping jaws 34, 40 is greater than the distance A 'indicated between the leading edges 24 of the two printed products 12 held by a gripper 16 (FIG. 1). The distance A 'corresponds to the distance A between the leading edges 24 of the printed products 12 in the supplied scale formation S. The third gripper 16 is shown during the closing process, and the fourth gripper 16 shown in FIG. 1 is in the open position.

Bei der Funktionsbeschreibung der in den Fig. 1 und 2 dargestellten Vorrichtung verfolgen wir einen Greifer 16 bei seiner Bewegung in Förderrichtung F durch den Ueber­nahmebereich 14. Am Anfang des Uebernahmebereiches 14 ist das Greifergehäuse 32 infolge des kurzen Abstandes zwischen der Schwenkkulisse 54 und dem Führungskanal 26 im Gegenuhrzeigersinn derart verschwenkt, dass die vor­laufende Klemmbacke 34, bezüglich der Förderrichtung F, schräg nach vorne zeigt (s. hinterster Greifer 16 der Fig. 1). Sobald nun die Schwenkrolle 36 in jenen Bereich der Schwenkkulisse 54 gelangt, in welchem der Abstand zwischen der Schwenkkulisse 54 und dem Führungskanal 26 zunimmt, wird das Greifergehäuse 32 im Uhrzeigersinn verschwenkt (s. hinterster Greifer 16 der Fig. 2). Das Zugorgan 28 sowie der Bandförderer 10 sind so synchroni­siert, dass zu Beginn dieses Schwenkvorganes die vorlau­ fende Kante 24 des vordersten Druckproduktes 12 der Schuppenformation S zwischen die Klemmbacken 34, 40 ein­läuft, wie dies in der Fig. 2 dargestellt ist. Da die Schliessrolle 46 an der Schliesskulisse 56 abrollt, und die Schliesskulisse 56 ungefähr parallel zum Führungska­nal 26 verläuft, behält die nachlaufende Klemmbacke 40 bezüglich der Förderrichtung F seine Richtung bei, was infolge der Schwenkbewegung des Greifergehäuses 32 und somit der Klemmbacke 34 die Schliessbewegung des Grei­fers 16 zur Folge hat. Während der Schliessbewegung läuft das dem zuerst in den Greifer 16 eingeführte Druckereiprodukt 12 nachfolgende Druckereiprodukt 12 zwischen die Klemmbacken 32, 40 ein (s. Fig. 1). Kurz bevor die Schwenkrolle 36 das Ende des vom Führungskanal 26 divergierenden Teils der Schwenkkulisse 54 erreicht hat, kommt die Rastnase 44 des Schliesshebels 42 am Klinkenhebel 50 zur Anlage, schwenkt diesen im Gegenuhr­zeigersinn zurück, bis sie unter Zurückschwenkung des Klinkenhebels 50 im Uhrzeigersinn in dessen Rastnut 48 verklinkt. Sobald bei der Schliessbewegung des Greifers 16 der Gummibelag 52 der Klemmbacke 40 die erfassten Druckereiprodukte 12 gegen den Gummibelag 52 der vorlau­fenden Klemmbacke 34 drückt, wird die Druckkraft infolge der Federeigenschaften der Klemmbacke 40 vergrössert, so dass die beiden erfassten Druckereiprodukte 12 einen si­cheren Halt finden. Bei der Weiterbewegung in Förder­richtung F gibt die Schliesskulisse 56 im Bereich der Ablaufkante 58 die Schliessrolle 46 frei, so dass die Klemmbacke 40 nun alleine vom Klinkenhebel 50 in ihrer Schliessstellung gehalten wird (s. dazu in den Figuren 1 und 2 je die beiden vordersten Greifer 16).In the functional description of the device shown in FIGS. 1 and 2, we track a gripper 16 as it moves in the conveying direction F through the takeover area 14. At the start of the takeover area 14, the gripper housing 32 is due to the short distance between the pivot link 54 and the guide channel 26 pivoted in the counterclockwise direction in such a way that the leading clamping jaw 34 points obliquely forward with respect to the conveying direction F (see rearmost gripper 16 of FIG. 1). As soon as the swivel roller 36 arrives in that area of the swivel link 54 in which the distance between the swivel link 54 and the guide channel 26 increases, the gripper housing 32 is pivoted clockwise (see rearmost gripper 16 of FIG. 2). The traction element 28 and the belt conveyor 10 are synchronized in such a way that at the beginning of this swiveling element the forward fende edge 24 of the foremost printed product 12 of the scale formation S runs between the jaws 34, 40, as shown in FIG. 2. Since the closing roller 46 rolls on the closing link 56, and the closing link 56 runs approximately parallel to the guide channel 26, the trailing clamping jaw 40 maintains its direction with respect to the conveying direction F, which due to the pivoting movement of the gripper housing 32 and thus the clamping jaw 34, the closing movement of the gripper 16 results. During the closing movement, the printed product 12 following the printed product 12 first introduced into the gripper 16 runs between the clamping jaws 32, 40 (see FIG. 1). Shortly before the swivel roller 36 has reached the end of the part of the swivel link 54 which diverges from the guide channel 26, the latching lug 44 of the locking lever 42 comes into contact with the ratchet lever 50, pivots it back in a counterclockwise direction until it swings back in a clockwise direction into the latching groove 48 latched. As soon as, during the closing movement of the gripper 16, the rubber covering 52 of the clamping jaw 40 presses the detected printed products 12 against the rubber covering 52 of the leading clamping jaw 34, the compressive force is increased as a result of the spring properties of the clamping jaw 40, so that the two detected printed products 12 find a secure hold. When moving further in the direction of conveyance F, the closing link 56 releases the closing roller 46 in the region of the trailing edge 58, so that the clamping jaw 40 is now held in its closed position only by the latch lever 50 (see FIGS. 1 and 2, the two foremost grippers in each case 16).

Die von einem Greifer 16 erfassten Druckereiprodukte 12 werden ohne Aenderung des Abstandes A, A′ zwischen den vorlaufenden Kanten 24 von der Schuppenformation S abge­schält; so wird die vorlaufende Kante 24 des vordersten Druckereiproduktes 12 der Schuppenformation S freige­legt. Für die Freigabe der von den Greifern 16 gehalte­nen Druckereiprodukte 12 werden die Schwenkrollen 36 er­neut in eine nicht dargestellte Schwenkkulisse 54 einge­fahren, und der Klinkenhebel 50 läuft auf eine ebenfalls nicht dargestellte Oeffnungskulisse auf, welche den Klinkenhebel 50 im Gegenuhrzeigersinn verschwenkt und somit die Rastnase 44 und den Schliesshebel 42 freigibt. Dadurch wird die Klemmbacke 40 selbsttätig in die Offen­stellung überführt, und die Druckereiprodukte 12 stehen mit unverändertem Abstand A, A′ für die Weiterverarbei­tung zur Verfügung. Es ist somit einleuchtend, dass pro­blemlos und ohne weitere Massnahmen wieder eine Schup­penformation gebildet werden kann, bei welcher der Ab­stand A, A′ der Druckereiprodukte 12 gegenüber dem Ab­stand A, A′ der Druckereiprodukte 12 im ankommenden Schuppenstrom S unverändert ist.The printed products 12 gripped by a gripper 16 are peeled off from the scale formation S without changing the distance A, A 'between the leading edges 24; thus the leading edge 24 of the foremost printed product 12 of the scale formation S is exposed. To release the printed products 12 held by the grippers 16, the swivel rollers 36 are again moved into a swivel link 54, not shown, and the pawl lever 50 runs onto an opening backdrop, also not shown, which pivots the pawl lever 50 counterclockwise and thus the detent 44 and releases the locking lever 42. As a result, the jaw 40 is automatically transferred to the open position, and the printed products 12 are available with the same distance A, A 'for further processing. It is therefore obvious that a scale formation can be formed again easily and without further measures, in which the distance A, A 'of the printed products 12 is unchanged compared to the distance A, A' of the printed products 12 in the incoming scale stream S.

Der Bandförderer 10 des zweiten Ausführungsbeispiels ge­mäss Fig. 3 weist ebenfalls ein, in Zuführrichtung Z um­laufend angetriebenes Endlosband 20 auf, welches um die Umlenkwalze 22 geführt ist. In der vom Bandförderer 10 dem Uebernahmebereich 14 zugeführten Schuppenformation S liegt jedes Druckereiprodukt 12 auf dem vorlaufenden auf.The belt conveyor 10 of the second exemplary embodiment according to FIG. 3 likewise has an endless belt 20 which is driven in a rotating manner in the feed direction Z and which is guided around the deflection roller 22. In the scale formation S fed from the belt conveyor 10 to the takeover area 14, each printed product 12 lies on top of the preceding one.

Die Förderrichtung F des Wegförderers 18 verläuft, in Zuführrichtung Z gesehen, von der Oberseite der Drucke­ reiprodukte 12 schräg nach unten. Der Wegförderer 18 weist ebenfalls einen Führungskanal 26 auf, in welchem ein strichpunktiert angedeutetes und umlaufend angetrie­benes Zugorgan 28 geführt ist. Am Zugorgan 28 sind eben­falls in einem Mittenabstand B hintereinander angeordne­te, einzeln steuerbare Greifer 16 befestigt. Der Aufbau und die Funktionsweise dieser Greifer 16 sind in der CH-PS 592 562 und der entsprechenden US-PS 3,955,667 nä­her beschrieben. Das Greifergehäuse 32 ist am Zugorgan 28 nicht schwenkbar befestigt, und an ihm ist die feste Klemmbacke 60 ausgebildet. Im Greifergehäuse 32 ist ein Schaft 62 in Richtung seiner Längsachse schiebbar und um diese schwenkbar gelagert. Die Längsachse verläuft quer zur Förderrichtung F und ungefähr senkrecht zur Ebene der zu erfassenden Druckereiprodukte 12. Der Schaft 62 ist gegen die Offenstellung, wie sie in der Fig. 3 in Förderrichtung F gesehen im hintersten Greifer 16 darge­stellt ist, vorgespannt. Dabei ist die am Schaft 62 be­festigte Klemmbacke 64 etwa um 90° zur Förderrichtung F verschwenkt. Mit dem Schaft 62 ist eine Schliessrolle 46 wirkverbunden, welche beim Auflaufen auf eine am Füh­rungskanal 26 befestigte Schliesskulisse 56 den Schaft 62 und damit auch die Klemmbacke 64 in die Schliessstel­lung des Greifers 16 überführt. Dabei wird der Schaft 62 um ca. 90° geschwenkt, so dass die Klemmbacke 64, in Förderrichtung F gesehen, nach rückwärts und ungefähr parallel zur Klemmbacke 60 gerichtet ist, wie dies beim zweithintersten Greifer 16 dargestellt ist. Beim Weiter­transport der Greifer 16 wird er ganz geschlossen und klemmt die vom Bandförderer 10 zugeführten Druckereipro­dukte 12 zwischen den freien Enden der Klemmbacken 60, 64 ein. Der Schaft 62 wird mittels des Klinkenhebels 50 in der Schliessstellung gehalten. Bei dem in der Fig. 3 dargestellten Greifer 16 ist das freie Ende der nachlau­fenden, festen Klemmbacke 60 mit einem Gummibelag 52 überzogen. Der Abstand zwischen den vorlaufenden Kanten 24 zweier von einem Greifer 16 erfassten Druckereipro­dukten 12 ist mit A′ bezeichnet und entspricht dem Ab­stand A zwischen den vorlaufenden Kanten 24 der Drucke­reiprodukte 12 in der zugeführten Schuppenformation S, die Tiefe der Greifer 16 ist grösser als dieser Abstand A′ bzw. A. Dem Bandförderer 10 ist ein Leitblech 66 nachgeschaltet, welches parallel zur Förderrichtung F des Wegförderers 18 verläuft und an welchem die nachlau­fenden Kanten der weggeführten Druckereiprodukte 12 gleiten.The conveying direction F of the conveyor 18 runs, seen in the feed direction Z, from the top of the prints rice products 12 diagonally downwards. The conveyor 18 also has a guide channel 26, in which a traction element 28, indicated by dash-dotted lines and driven in rotation, is guided. Individually controllable grippers 16 are also attached to the traction element 28 at a center distance B one behind the other. The structure and operation of this gripper 16 are described in more detail in CH-PS 592 562 and the corresponding US-PS 3,955,667. The gripper housing 32 is not pivotally attached to the pulling element 28, and the fixed clamping jaw 60 is formed on it. In the gripper housing 32, a shaft 62 can be pushed in the direction of its longitudinal axis and is pivoted about it. The longitudinal axis runs transversely to the conveying direction F and approximately perpendicular to the plane of the printed products 12 to be detected. The shaft 62 is biased against the open position, as shown in the rearmost gripper 16 in FIG. 3 in the conveying direction F. The jaw 64 fastened to the shaft 62 is pivoted about 90 ° to the conveying direction F. A closing roller 46 is operatively connected to the shaft 62 and, when it runs onto a closing link 56 fastened to the guide channel 26, transfers the shaft 62 and thus also the clamping jaw 64 into the closed position of the gripper 16. Here, the shaft 62 is pivoted by approximately 90 °, so that the clamping jaw 64, viewed in the conveying direction F, is directed backwards and approximately parallel to the clamping jaw 60, as is shown in the second rearmost gripper 16. When the gripper 16 is transported further, it is closed completely and clamps the printed products 12 fed by the belt conveyor 10 between the free ends of the clamping jaws 60, 64. The shaft 62 is moved by means of the ratchet lever 50 held in the closed position. In the gripper 16 shown in FIG. 3, the free end of the trailing, fixed clamping jaw 60 is covered with a rubber covering 52. The distance between the leading edges 24 of two printed products 12 gripped by a gripper 16 is designated A 'and corresponds to the distance A between the leading edges 24 of the printed products 12 in the supplied scale formation S, the depth of the grippers 16 is greater than this distance A. 'Or A. The belt conveyor 10 is followed by a baffle 66, which runs parallel to the direction of conveyance F of the conveyor 18 and on which the trailing edges of the printed products 12 slide away.

Die Geschwindigkeit des Wegförderers 18 ist mit v₂ be­zeichnet. Die Zuführgeschwindigkeit v₁ des Bandförderers 10 und die Fördergeschwindigkeit v₂ des Wegförderers 18 sind so gewählt, dass in jener Zeit, in welcher die zu­geführten Druckereiprodukte 12 den doppelten Abstand A zwischen zwei Druckereiprodukten 12 zurücklegen, die Greifer 16 des Wegförderers 18 um einen Abstand B zwi­schen den Greifern 16 weitertransportiert werden. Es wird somit sichergestellt, dass jedem Greifer 16 zwei Druckereiprodukte 12 zugeführt werden.The speed of the conveyor 18 is designated v₂. The feed speed v₁ of the belt conveyor 10 and the conveying speed v₂ of the conveyor 18 are selected so that at that time in which the supplied printed products 12 cover twice the distance A between two printed products 12, the grippers 16 of the conveyor 18 by a distance B between them Grippers 16 are transported on. It is thus ensured that two gripper products 12 are fed to each gripper 16.

In diesem Zusammenhang sei noch erwähnt, dass die Schliesskulisse 56 im wesentlichen parallel zur Zuführ­richtung Z verläuft und derart angeordnet ist, dass die vorlaufende steuerbare Klemmbacke 64 während dem Einfah­ren der Druckereiprodukte 12 seine Lage in bezug zur Förderebene des Bandförderers 10 und somit zur Ebene der zu erfassenden Druckereiprodukte 12 im wesentlichen bei­behält.In this context, it should also be mentioned that the closing link 56 runs essentially parallel to the feed direction Z and is arranged in such a way that the leading controllable clamping jaw 64 during its insertion of the printed products 12 has its position in relation to the conveying plane of the belt conveyor 10 and thus to the plane of the Maintains printed products 12 to be detected.

Die Vorrichtung gemäss Fig. 3 funktioniert wie folgt: Die Greifer 16 gelangen in Offenstellung in den Ueber­nahmebereich 14. Der Bandförderer 10 und Wegförderer 18 sind so synchronisiert, dass beim Auflaufen der Schliessrolle 46 auf die Schliesskulisse 56 und somit beim Verschwenken der Klemmbacke 64, diese im Bereich der vorlaufenden Kante 24 des hinteren, zu erfassenden Druckereiproduktes 12 an die Unterseite des vorderen Druckereiproduktes 12 zur Anlage kommt. Während dem wei­teren Schliessvorgang ist die Relativbewegung zwischen der steuerbaren Klemmbacke 64 und der zu erfassenden Druckereiprodukte 12 nur noch gering, und während diese Klemmbacke 64 von der Schliesskulisse 56 in ihrer Lage bezüglich der Ebene der zu erfassenden Druckereiprodukte 12 ungefähr gleichgehalten wird, nähert sich die in För­derrichtung F bewegte, feste Klemmbacke 60 den zu erfas­senden Druckereiprodukten 12 von oben, bis diese Drucke­reiprodukte 12 zwischen den beiden Klemmbacken 60, 64 festgeklemmt sind. Die erfassten Druckereiprodukte 12 werden in Richtung gegen abwärts weggeführt, so dass die vorlaufenden Kanten 24 der nächsten zu erfassenden Druckereiprodukte 12 freigelegt werden.The device according to FIG. 3 functions as follows: The grippers 16 reach the takeover area 14 in the open position. The belt conveyor 10 and the conveyor 18 are synchronized in such a way that when the closing roller 46 runs onto the closing link 56 and thus when the clamping jaw 64 is pivoted, the latter comes into contact with the underside of the front printed product 12 in the region of the leading edge 24 of the rear printed product 12 to be detected. During the further closing process, the relative movement between the controllable clamping jaw 64 and the printed products 12 to be detected is only slight, and while this clamping jaw 64 is held approximately the same in its position with respect to the plane of the printed products 12 to be detected, that in FIG Conveying direction F moved, fixed jaw 60 of the printed products 12 to be detected from above until these printed products 12 are clamped between the two jaws 60, 64. The detected printed products 12 are guided away in the downward direction, so that the leading edges 24 of the next printed products 12 to be detected are exposed.

Für die Abgabe der erfassten Druckereiprodukte 12 werden die Klinkenhebel 50 mittels einer nicht dargestellten Oeffnungskulisse im Uhrzeigersinn verschwenkt, wodurch der Schaft 62 und die an ihm fixierte Klemmbacke 64 in die Offenstellung zurückgeführt werden, und die freige­gebenen Druckereiprodukte 12 mit ihrem ursprünglichen Abstand A, A′ auf beispielsweise ein Förderband abgelegt werden, womit auf diesem Förderband wieder eine Schup­penformation gebildet wird, welche die ursprünglichen Abstände A, A′ zwischen den vorlaufenden Kanten 24 aufweist.For the delivery of the detected printed products 12, the latch levers 50 are pivoted clockwise by means of an opening backdrop (not shown), whereby the shaft 62 and the jaw 64 fixed to it are returned to the open position, and the released printed products 12 with their original ones Distance A, A 'are placed on, for example, a conveyor belt, which again forms a scale formation on this conveyor belt, which has the original distances A, A' between the leading edges 24.

Es ist zu beachten, dass die Förderichtung F bei einer Vorrichtung gemäss der Fig. 3, bei welcher in der zuge­führten Schuppenformation S jedes Druckereiprodukt 12 auf dem vorlaufenden aufliegt, ungefähr parallel zur Zu­führrichtung Z oder, wie dies in der Fig. 3 gezeigt ist, von der Oberseite der Druckereiprodukte 12 nach abwärts gerichtet ist. Bei einer Förderrichtung F, die ungefähr parallel zur Zuführrichtung Z verläuft, wird das Ergrei­fen der zu erfassenden Druckereiprodukte 12 im Bereich ihrer vorlaufenden Kanten 24 dadurch sichergestellt, dass das nach unten vorstehende freie Ende des Schaftes 24 die schon vom vorlaufenden Greifer 16 erfassten Druckereiprodukte 12 in einer Richtung gegen unten weg­drückt und so die zu erfassenden vorlaufenden Kanten 24 freilegt.It should be noted that the conveying direction F in a device according to FIG. 3, in which each printed product 12 rests on the leading one in the supplied scale formation S, approximately parallel to the feed direction Z or, as shown in FIG. 3, is directed downwards from the top of the printed products 12. With a conveying direction F, which runs approximately parallel to the feed direction Z, the gripping of the printed products 12 to be gripped is ensured in the region of their leading edges 24 by the free end of the shaft 24 projecting downwards from the printed products 12 already gripped by the forward gripper 16 pushes away in a direction downward and thus exposes the leading edges 24 to be detected.

Es ist einleuchtend, dass bei beiden Ausführungsbeispie­len durch Verkleinerung der Zuführgeschwindigkeit v₁ bzw. Vergrösserung der Fördergeschwindigkeit v₂ des Weg­förderers 18 oder bei gleichbleibenden Geschwindigkeiten v₁, v₂, aber doppeltem Abstand A zwischen den vorlaufen­den Kanten 24 der Druckereiprodukte 12 in der zugeführ­ten Schuppenformation S jeder Greifer 16 jeweils nur ein einziges Druckereiprodukt 12 erfasst und wegfördert.It is obvious that in both exemplary embodiments, by reducing the feed speed v 1 or increasing the conveying speed v 2 of the conveyor 18 or at constant speeds v 1, v 2, but double the distance A between the leading edges 24 of the printed products 12 in the scales formation S supplied, each gripper 16 only a single printed product 12 detected and transported away.

Es ist selbstverständlich auch möglich, die gezeigten Vorrichtungen und insbesondere die Greifer 16 so auszu­bilden, dass jeweils drei oder allenfalls auch mehr Druckereiprodukte 12 von einem Greifer 16 erfasst und weggeführt werden, wobei auch in diesem Fall der Abstand A zwischen den Druckereierzeugnissen 12 im wesentlichen erhalten bleibt.It is of course also possible to design the devices shown and in particular the grippers 16 such that three or possibly more printed products 12 are gripped and guided away by a gripper 16, the distance A between the printed products 12 also essentially being maintained in this case remains.

Anstelle von gefalteten Druckereiprodukten 12 könnten auch Einzelblätter in einer Schuppenformation S zuge­führt und mittels des Wegförderers 18 wegtransportiert werden.Instead of folded printed products 12, single sheets could also be fed in a scale formation S and transported away by means of the conveyor 18.
