  • Each pivot 32, 33 is mounted at one end of a control lever 35 or 36 in this.
  • One of these control levers is designed as a straight lever 35, while the opposite control lever 36 is bent.
  • Each collecting conveyor 8 is thus mounted on one side in a straight control lever 35 and on the other side in a cranked control lever 36, as can be seen in particular from FIG. 3.
  • a straight control lever 35 is arranged between two cranked control levers 36 on each side of the collecting conveyor 8, i.e. straight and cranked control levers 35, 36 alternate.

  • the first section 45 of the control cams 41, 42 is designed in the form of a circular arc and extends coaxially with the axis of rotation 4a. This first section 45, viewed in the direction of rotation A of the collecting drum 5, merges approximately at the point denoted by F into the second section 47, the distance to the axis of rotation 4a of which, viewed in the direction of rotation A, becomes smaller and smaller.
  • the third section 47 of the control curves 41, 42 begins approximately at the point designated by G. and merges into the first section 45 approximately at point H. Viewed in the direction of rotation A, the distance of the third cam section 47 from the circumferential axis 4a from the transition point G increases.
  • control cams 41, 42 causes the control levers 35, 36 to be pivoted clockwise inward against the rotation axis 4a as the control rollers 39 have passed point F during the rotation of the collecting conveyor 8 in the direction of arrow A.
  • the collecting conveyors 8 are thus also pivoted inwards, which, at a given speed of the collecting drum 5, results in a reduction in the rotational speed of the collecting conveyors 8 because of the smaller distance from the axis of rotation 4a.
  • the distance between adjacent collecting conveyors 8 is increased, the greatest distance being designated by a in FIG. 4.
  • the control levers 35, 36 with their control rollers 38 pass the transition point G, the control levers 35, 36 begin to pivot counterclockwise again outwards from the axis of rotation 4a.
  • the transition point G is located approximately in the transition region 13a (or 14a, 15a), in which, as described with reference to FIGS. 1 and 2, the printed sheets 16, 17, 18 are placed on the collecting conveyor 8. Due to the described design of the control cams 41, 42, the distance between adjacent collecting conveyors 8 in this transfer area 13a corresponds approximately to the distance between the printed sheets 16, 17, 18 in the incoming scale formation. This scale spacing corresponds approximately to the smallest distance b between successive collecting conveyors 8. This ensures that the supplied conveyors 16, 17, 18 are correctly taken over by the collecting conveyors 8. The fact that, as mentioned, the rotational speed of the collecting conveyors 8 in this transfer area 13a is reduced further contributes to this. Outside this transfer area 13a, the distance between adjacent collecting conveyors 8 is greater, which enables the collecting conveyors 8 to move past one another undisturbed at the two outermost lateral points (left and right in FIG. 4).
  • the collecting conveyors 8 are rotated in the manner to be described below during their rotation around the rotation axis 4a about their axis of rotation 34 such that they keep their vertical position with their ridge 8a always pointing upwards.

  • two sprockets 50, 51 sit on these drive shafts 49.
  • the sprockets 50, 51 of adjacent drive shafts 49 are connected to one another by chains 52, the drive shafts 49 being divided into two separate groups, as shown in FIG. 4 emerges.
  • a sprocket 54 which is arranged coaxially to the rotational axis 4a in a fixed position, ie not rotating.
  • the collecting conveyors 8 are turned counterclockwise during their rotation around the axis of rotation 4a, i.e. in the direction of arrow I (Fig. 4), rotated about its axis of rotation 34 so that they maintain their vertical position.
  • the conveying arrangements of the collecting conveyors 8 are preferably driven by the described relative rotation of the collecting conveyors 8 with respect to the control levers 35, 36, as is described in more detail in the Swiss patent application No. 2828/85.
  • the feed speed of the conveyor arrangements is thus derived from the speed at which the collecting conveyors 8 rotate about their axis of rotation 34.
  • This rotational speed of the collecting conveyors 8 changes during the passage of the second and third sections 46, 47 of the control cams 41, 42 through the associated control rollers 39. This accordingly has the consequence that the feed speed of the conveying arrangements of the collecting conveyors 9 also changes, i.e. a slowdown and subsequent acceleration. While the printed sheets 16, 17, 28 are being conveyed by the collecting conveyors 8 at reduced speed, processing operations such as stapling, sticking on a label and the like can be carried out on these printed sheets.
  • the feed conveyors 13, 14, 15 can feed both individual printed sheets 16, 17, 18 and also a plurality of folded printed sheets lying one inside the other. Center-folded printed sheets which do not have a protruding edge section can also be processed, it being necessary for these printed sheets to be opened in a different manner than that described.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Sammeln von gefalzten Druckbogen gemäss Oberbegriff des Anspruches 1.The present invention relates to a device for collecting folded printed sheets according to the preamble of claim 1.

Bei bekannten Vorrichtungen zum Sammeln von Druckbogen sind längs eines Sammelförderers eine Anzahl von Auflegestationen angeordnet, an denen die Druckbogen von einem Stapel abgezogen, geöffnet und rittlings auf den Sammelförderer bzw. auf die sich bereits auf diesem befindlichen Druckbogen aufgelegt werden (siehe beispielsweise CH-PS 412 795). Da die Druckbogen jeweils einzeln von Stapeln abgezogen werden müssen, lässt sich die Arbeitsgeschwindigkeit solcher Vorrichtungen nicht beliebig erhöhen. Im weiteren müssen aus den die .Rotationsdruckmaschine in Schuppenformation verlassenden Druckbogen zuerst Stapel gebildet werden, die dann zu den Auflegestationen verbracht werden müssen. Damit ist jedoch ein ins Gewicht fallender Aufwand an Zeit, Installationen und Geräten und/oder menschlicher Arbeitskraft erforderlich.In known devices for collecting printed sheets, a number of lay-up stations are arranged along a collecting conveyor, at which the printed sheets are removed from a stack, opened and placed astride the collecting conveyor or on the printed sheets already located thereon (see, for example, CH-PS 412 795). Since the printed sheets have to be removed individually from stacks, the working speed of such devices cannot be increased at will. Furthermore, stacks must first be formed from the printing sheets leaving the rotary printing machine in scale formation, which then have to be brought to the lay-up stations. However, this requires a considerable amount of time, installations and equipment and / or human labor.

Diese Nachteile sind bei der aus der EP-OS 0 095 603 und der entsprechenden US-PS 4 489 930 bekannten Einrichtung weitgehend vermieden, da die Druckprodukte kontinuierlich, d.h. direkt in der anfallenden Schuppenformation, dem Sammelförderer zugeführt werden und somit vorgängig nicht mehr zu einem Stapel aufgeschichtet zu werden brauchen. Doch hat diese Vorrichtung den Nachteil einer verhältnismässig grossen Baulänge, da die Zuförderer zumindest im Abgabebereich der Druckbogen dieselbe Förderrichtung haben wie der Sammelförderer, der die Druckbogen in einer etwa rechtwinklig zu derem Falz verlaufenden Richtung fördert. Auch bei dieser Vorrichtung lässt sich die Arbeitsgeschwindigkeit nicht im gewünschten Ausmass steigern.These disadvantages are largely avoided in the device known from EP-OS 0 095 603 and the corresponding US Pat. No. 4,489,930, since the printed products are continuous, i.e. directly in the resulting scale formation, are fed to the collecting conveyor and therefore no longer need to be stacked up in a stack beforehand. However, this device has the disadvantage of a relatively large overall length, since the feed conveyors, at least in the discharge area of the printed sheets, have the same conveying direction as the collecting conveyor, which conveys the printed sheets in a direction approximately perpendicular to the fold. With this device, too, the working speed cannot be increased to the desired extent.

Aus der nicht vorveröffentlichten DE-OS 3 620 945 der Ferag AG ist nun eine Vorrichtung zum Sammeln von Druckbogen bekannt, welche in einer Halterung gelagerte, um eine Umlaufachse herum angeordnete Sammelförderer aufweist, deren Förderrichtung parallel zur Umlaufachse verläuft und die um letztere umlaufend antreibbar sind. Die Abstände zwischen jeweils benachbarten Sammelförderern bleiben während des Umlaufes fest. Diese Abstände müssen nun einerseits so gross sein, dass sich die Sammelförderer während ihres Umlaufens ungehindert aneinander vorbeibewegen können und sind andererseits auf den gegenseitigen Abstand der in Schuppenformation zugeführten und auf die Sammelförderer aufzulegenden Druckbogen abzustimmen.From the unpublished DE-OS 3 620 945 by Ferag AG, a device for collecting printed sheets is now known which has collecting conveyors mounted in a holder and arranged around a circumferential axis, the conveying direction of which runs parallel to the circumferential axis and which can be driven circumferentially around the latter . The distances between adjacent collecting conveyors remain fixed during the circulation. On the one hand, these distances must be so large that the collecting conveyors can move past each other unhindered during their circulation and, on the other hand, must be matched to the mutual distance of the printed sheets that are fed in scale form and placed on the collecting conveyors.

Aus der US-PS 2 969 981 ist eine Vorrichtung mit um eine horizontale Achse umlaufenden Transportelementen bekannt, auf die an einer Beschickungsstelle gefalzte Druckbogen in Hängelage aufgelegt werden. Diese Druckbogen werden dann an eine Abgabestelle transportiert und dort in horizontaler Lage einem Wegförderer übergeben. Diese Vorrichtung dient nur zum Transport, nicht jedoch zum Sammeln von Druckbogen.From US Pat. No. 2,969,981 a device with transport elements rotating around a horizontal axis is known, onto which folded printed sheets are placed in a hanging position at a loading point. These printed sheets are then transported to a delivery point and transferred there to a conveyor in a horizontal position. This device is only used for transport, but not for collecting printed sheets.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die bei möglichst einfachem Aufbau und platzsparender Bauweise ein Sammeln von Druckbogen mit grösserer Geschwindigkeit als bisher erlaubt.The present invention is based on the object of providing a device of the type mentioned at the outset which, with the simplest possible construction and space-saving construction, allows printing sheets to be collected at a higher speed than previously.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Da mehrere umlaufende Sammelförderer vorgesehen sind, können gleichzeitig mehrere Sammelvorgänge ablaufen. Jede Beschickungsvorrichtung beschickt nun mehrere Sammelförderer, so dass an jeder Beschickungsstelle in zeitlich kurzer Folge Druckbogen auf jeweils einen Sammelförderer aufgelegt werden. Dabei ist es nicht erforderlich, die Vorschubgeschwindigkeit der Sammelförderer entsprechend zu erhöhen, da für den Vorschub der Druckbogen im wesentlichen die Zeit eines Umlaufes der Sammelförderer um die gemeinsame Umlaufachse zur Verfügung steht. Da die Druckbogen eine schraubenlinien-oder wendelförmige Bahn durchlaufen, ist trotz grosser Leistungsfähigkeit eine in Vorschubrichtung gesehen verhältnismässig geringe Baulänge möglich.Since several revolving collecting conveyors are provided, several collecting processes can take place at the same time. Each loading device now feeds several collecting conveyors, so that printed sheets are placed on each collecting conveyor in short succession at each loading point. It is not necessary to correspondingly increase the feed speed of the collecting conveyors, since essentially the time for one rotation of the collecting conveyors around the common rotating axis is available for feeding the printed sheets. Since the printed sheets run through a helical or helical path, a relatively small overall length is possible in spite of the high performance in the feed direction.

Durch das Verändern des Abstandes zwischen jeweils benachbarter Sammelförderer während des Umlaufes um die Umlaufachse kann erreicht werden, dass einerseits sich die Sammelförderer während des Umlaufens aneinander vorbeibewegen können, ohne aneinander anzustossen und ohne dass die aufliegenden Druckbogen beschädigt werden und dass andererseits die Sammelförderer die in Schuppenformation ankommenden Druckbogen einwandfrei aufzunehmen in der Lage sind.By changing the distance between adjacent collecting conveyors during the rotation around the rotation axis, it can be achieved that on the one hand the collecting conveyors can move past one another during the rotation without bumping against each other and without the printed sheets lying on being damaged and on the other hand the collecting conveyors in scale formation incoming printing sheets are able to take up properly.

Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes näher erläutert. Es zeigt rein schematisch:

  • Fig. 1 eine Sammelvorrichtung in perspektivischer Ansicht,
  • Fig. 2 die Sammelvorrichtung gemäss Fig. 1 in Stirnansicht,
  • Fig. 3 in gegenüber den Figuren 1 und 2 vergrössertem Massstab die Sammelvorrichtung in Seitenansicht, und
  • Fig. 4 einen Schnitt etwa entlang der Linie IV-IV in Fig. 3.
An exemplary embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing. It shows purely schematically:
  • 1 is a perspective view of a collecting device,
  • 2 shows the collecting device according to FIG. 1 in front view,
  • Fig. 3 on an enlarged scale compared to Figures 1 and 2, the collecting device in side view, and
  • FIG. 4 shows a section approximately along the line IV-IV in FIG. 3.

Anhand der Fig. 1 und 2, in denen eine Sammelvorrichtung 1 nur ganz schematisch dargestellt ist, soll nun vorerst der grundsätzliche Aufbau dieser Sammelvorrichtung 1 erläutert werden, bevor anhand der Fig. 3 und 4 näher auf konstruktive Einzelheiten eingegangen wird.1 and 2, in which a collecting device 1 is shown only very schematically, the basic structure of this collecting device 1 will now be explained for the time being, before constructive details are discussed in more detail with reference to FIGS. 3 and 4.

Die Sammelvorrichtung 1 weist eine Grundplatte 2 mit Lagerböcken 3 und 3' auf, in denen die Welle 4 einer Sammeltrommel 5 gelagert ist. In Fig. 2 ist der Lagerbock 3 als durchsichtig angenommen. Auf der Welle 4 sind in einem Abstand voneinander zwei scheibenförmige Lagerelemente 6, 7 befestigt, von denen in Fig. 2 das Lagerelement 6 ebenfalls als durchsichtig angenommen ist. Zwischen den Lagerelementen 6, 7 ist eine Anzahl von Sammelförderern 8 angeordnet, die in den Lagerelementen 6 und 7 drehbar gelagert sind, wie das.anhand der Fig. 3 und 4 noch näher erläutert werden wird. Die Sammelförderer 8 verlaufen parallel zueinander und zur Welle 4 der Sammeltrommel 5 und sind um diese Welle 4 herum angeordnet. Auf der Welle 4 sitzt ein Kettenrad 9, über das eine Kette 10 geführt ist, die über ein weiteres Kettenrad 11 verläuft. Letzteres sitzt auf der Abtriebswelle eines Antriebes 12, mittels dem die Sammeltrommel 5 samt den Sammelförderern 8 in Richtung des Pfeiles A umlaufend angetrieben wird. Die Umlaufachse ist mit 4a bezeichnet.The collecting device 1 has a base plate 2 with bearing blocks 3 and 3 ', in which the shaft 4 of a collecting drum 5 is mounted. In Fig. 2 the bearing block 3 is assumed to be transparent. Two disk-shaped bearing elements 6, 7 are fastened on the shaft 4 at a distance from one another, of which the bearing element 6 is also assumed to be transparent in FIG. 2. A number of collecting conveyors 8 are arranged between the bearing elements 6, 7 and are rotatably mounted in the bearing elements 6 and 7, as will be explained in more detail with reference to FIGS. 3 and 4. The collecting conveyors 8 run parallel to one another and to the shaft 4 of the collecting drum 5 and are arranged around this shaft 4. A sprocket 9 sits on the shaft 4, over which a chain 10 is guided, which extends over another sprocket 11. The latter sits on the output shaft of a drive 12, by means of which the collecting drum 5 together with the collecting conveyors 8 is driven in the direction of arrow A. The axis of rotation is designated 4a.

In Richtung der Längsachse der Welle 4, d.h. auch in Förderrichtung B der Sammelförderer 8, gesehen, sind hintereinander drei Zuförderer 13, 14, 15 für gefalzte Druckbogen 16, 17 bzw. 18 angeordnet. Die Zuförderer 13, 14, 15 enden in der Nähe des Umfanges der Sammeltrommel 5 und legen mit dieser einen Übergangsbereich 13a, 14a bzw. 15a für die Druckbogen 16, 17 bzw. 18 fest. In Förderrichtung B der Sammelförderer 8 gesehen hinter dem letzten Zuförderer 15 ist ein Wegförderer 19 angeordnet, der nur rein schematisch dargestellt ist und in einem gegenseitigen Abstand angeordnete Greifer 20 aufweist, die in Richtung des Pfeiles C umlaufend angetrieben sind. Diese Greifer erfassen die aus mehreren übereinanderliegenden Druckbogen 16, 17, 18 bestehenden Endprodukte 21 und bringen diese zu einer nicht dargestellten Weiterverarbeitungsstation.In the direction of the longitudinal axis of the shaft 4, i.e. also seen in the conveying direction B of the collecting conveyor 8, three feed conveyors 13, 14, 15 for folded printed sheets 16, 17 and 18 are arranged one behind the other. The feed conveyors 13, 14, 15 end in the vicinity of the circumference of the collecting drum 5 and use it to define a transition region 13a, 14a and 15a for the printed sheets 16, 17 and 18, respectively. Seen in the conveying direction B of the collecting conveyor 8, behind the last feed conveyor 15, there is a conveyor 19 which is shown only in a purely schematic manner and which has grippers 20 which are arranged at a mutual spacing and which are driven in rotation in the direction of arrow C. These grippers grip the end products 21 consisting of a plurality of printed sheets 16, 17, 18 lying one above the other and bring them to a further processing station, not shown.

Wie aus Fig. 2 hervorgeht, in der der vorderste Zuförderer 13 der gleich aufgebauten Zuförderer 13, 14, 15 dargestellt ist, weist jeder Zuförderer in einem gegenseitigen Abstand angeordnete Greifer 22 auf, die an einem nicht näher dargestellten, in einem Kanal 23 verlaufenden und in Richtung des Pfeiles D umlaufend angetriebenen Zugorgan befestigt sind. Die Greifer 22 halten die zugeführten Druckbogen 16 (bzw. 17 und 18) an ihrer Falzkante 24. Dabei werden die Druckbogen 16 (und auch die Druckbogen 17 und 18) durch den Zuförderer 13 (bzw. 14 und 15) so zugeführt, dass die der Falzkante 24 gegenüberliegende, offene Seitenkante 25 der Druckbogen 16 in Förderrichtung D des Zuförderers 13 gesehen vorauslaufen. Die Druckbogen 16 sind nicht mittig gefalzt, so dass der untenliegende Teil 1 6a der Druckbogen 16 länger ist als der andere Teil 16b und über letzteren an dieser offenen Seitenkante 25 vorsteht. Dieser vorstehende Abschnitt des untenliegenden Druckbogenteils 16a, der sogenannte Vorfalz, ist mit 26 bezeichnet.As can be seen from FIG. 2, in which the foremost feed conveyor 13 of the feed conveyors 13, 14, 15 of the same construction is shown, each feed conveyor has grippers 22 which are arranged at a mutual distance from one another and which extend in a channel 23 and not shown in detail are driven in the direction of arrow D rotating traction member attached. The grippers 22 hold the supplied printed sheets 16 (or 17 and 18) at their folded edge 24. The printed sheets 16 (and also the printed sheets 17 and 18) are fed by the feed conveyor 13 (or 14 and 15) so that the the open side edge 25 opposite the folded edge 24 of the printed sheets 16, as seen in the conveying direction D of the feed conveyor 13, run ahead. The printed sheets 16 are not folded in the middle, so that the part 16a below is the printed sheet 16 longer than the other part 16b and protrudes over the latter on this open side edge 25. This protruding section of the underlying printed sheet part 16a, the so-called pre-fold, is designated by 26.

Unterhalb jedes Zuförderers 13, 14, 15 ist eine Öffnungseinrichtung 27 angeordnet. Diese weist Festhalteklammern 28 auf, die in einem gegenseitigen Abstand an einem im Richtung des Pfeiles E umlaufend angetriebenen Zugorgan 29 befestigt sind. Die Festhalteklammern 28 sind in ihrer Umlaufrichtung E gesehen nach hinten offen und dienen dazu, den untenliegenden Druckbogenteil 16a am vorstehenden Randabschnitt 26 festzuhalten.An opening device 27 is arranged below each feed conveyor 13, 14, 15. This has retaining clips 28 which are attached at a mutual distance to a traction element 29 driven in the direction of the arrow E. The retaining clips 28 are open to the rear, as seen in their circumferential direction E, and serve to hold the printed sheet part 16a located below on the projecting edge section 26.

Sobald die Druckbogen 16 mit dem vorstehenden Randabschnitt 26 in den Wirkbereich der Festhalteklammern 28 gelangen, werden letztere geschlossen. Der durch eine Festhalteklammer 28 festgehaltene vorstehende Randbereich 26 wird zusammen mit der zugeordneten Festhalteklammer 28 um das vordere Umlenkrad 30 für das Zugorgan 29 herumgeführt. Das hat nun zur Folge, dass der untenliegende Druckbogenteil 16a im Bereich des vorstehenden Randabschnittes 26 vom anderen Druckbogenteil 16b abgehoben wird, wie das aus Fig. 2 hervorgeht. In die sich zwischen diesen beiden Druckbogenteilen 16a, 16b bildende Öffnung greift nun ein Sammelförderer 8 ein, der, wie erwähnt, in Richtung des Pfeiles A um die Achse 4a umlaufend angetrieben wird. Befindet sich der nach wie vor durch den Zuförderer 13 in Richtung des Pfeiles D geförderte Druckbogen 16 etwa oberhalb des bereits zwischen die beiden Druckbogenteile 16a und 16b eingefahrenen Sammelförderers 8, so wird der zugeordnete Greifer 22 geöffnet und der Druckbogen 16 freigegebene. Letzterer legt sich nun rittlings auf den satteldachförmig ausgebildeten Sammelförderer 8. Jeder dieser Sammelförderer 8 weist eine in den Figuren nicht gezeigte, umlaufend angetriebene Förderanordnung auf, die mit in Fig. 1 nur schematisch dargestellten Mitnehmern 31 versehen ist. Die Förderanordnung schiebt die aufgelegten Druckprodukte 16, 17, 18 in Längsrichtung der Sammelförderer 8, d.h. in Richtung des Pfeiles B (Fig. 1), vor.As soon as the printed sheets 16 with the projecting edge section 26 reach the effective area of the holding clips 28, the latter are closed. The protruding edge region 26 held in place by a retaining clip 28 is guided together with the associated retaining clip 28 around the front deflection wheel 30 for the tension member 29. The result of this is that the printed sheet part 16a located below is lifted off the other printed sheet part 16b in the region of the projecting edge section 26, as can be seen from FIG. 2. A collecting conveyor 8 now engages in the opening formed between these two printed sheet parts 16a, 16b, which, as mentioned, is driven in the direction of arrow A in a rotating manner around axis 4a. If the printed sheet 16, which is still conveyed by the feed conveyor 13 in the direction of arrow D, is located approximately above the collecting conveyor 8 which has already been inserted between the two printed sheet parts 16a and 16b, the assigned gripper 22 is opened and the printed sheet 16 is released. The latter now straddles the saddle roof-shaped collecting conveyor 8. Each of these collecting conveyors 8 has a rotatingly driven conveyor arrangement, not shown in the figures, which is provided with drivers 31, which are only shown schematically in FIG. The conveyor arrangement pushes the printed products 16, 17, 18 placed in the longitudinal direction of the collecting conveyors 8, i.e. in the direction of arrow B (Fig. 1).

Anhand der Fig. 3 und 4 wird nun die Lagerung der Sammelförderer 8 näher beschrieben, wobei Fig. 4 einen Schnitt durch die Sammelvorrichtung 1 etwa entlang der Linie IV-IV in Fig. 3 zeigt.The storage of the collecting conveyors 8 will now be described in more detail with reference to FIGS. 3 and 4, FIG. 4 showing a section through the collecting device 1 approximately along the line IV-IV in FIG. 3.

Jeder Sammelförderer 8 ist an jeder Stirnseite mit vorstehenden Drehzapfen 32, 33 versehen, die eine Drehachse 34 für die Sammelförderer 8 festlegen. Jeder Drehzapfen 32, 33 ist am einen Ende eines Steuerhebels 35 bzw. 36 in diesem gelagert. Einer dieser Steuerhebel ist als gerader Hebel 35 ausgebildet, während der gegenüberliegende Steuerhebel 36 abgekröpft ist. Jeder Sammelförderer 8 ist somit auf der einen Seite in einem geraden Steuerhebel 35 und auf der ändern Seite in einem abgekröpften Steuerhebel 36 gelagert, wie das insbesondere aus Fig. 3 hervorgeht. Dabei ist auf jeder Seite der Sammelförderer 8 jeweils ein gerader Steuerhebel 35 zwischen zwei abgekröpften Steuerhebeln 36 angeordnet, d.h. gerade und abgekröpfte Steuerhebel 35, 36 wechseln sich ab. Die Steuerhebel 35, 36 sind schwenkbar auf einem Lagerzapfen 37 gelagert, der am Lagerelement 6 bzw. 7 befestigt ist. Zwischen ihrer durch den Lagerzapfen 37 festgelegten Lagerstelle und der Lagerstelle für die Drehzapfen 32, 33 der Sammelförderer 8 steht von den Steuerhebeln 35, 36 nach aussen ein Arm 38 ab, der an seinem Ende eine Steuerrolle 39 trägt. Diese Steuerrolle greift in eine Führungsnut 40 einer als Kulisse ausgebildeten Steuerkurve 41 bzw. 42 ein. Die beiden Steuerkurven 41, 42 sind auf der Aussenseite der Lagerelemente 6, 7 angeordnet und an einem Rahmen 43 bzw. 44 befestigt, der mit der Grundplatte 2 verbunden ist. Die Steuerhebel 35, 36 sind nun so angeordnet, dass sie in Umlaufrichtung A der Sammeltrommel 5 gesehen nach vorne weisen, wie das insbesondere aus Fig. 4 hervorgeht.Each collecting conveyor 8 is provided on each end face with projecting pivots 32, 33 which define an axis of rotation 34 for the collecting conveyor 8. Each pivot 32, 33 is mounted at one end of a control lever 35 or 36 in this. One of these control levers is designed as a straight lever 35, while the opposite control lever 36 is bent. Each collecting conveyor 8 is thus mounted on one side in a straight control lever 35 and on the other side in a cranked control lever 36, as can be seen in particular from FIG. 3. A straight control lever 35 is arranged between two cranked control levers 36 on each side of the collecting conveyor 8, i.e. straight and cranked control levers 35, 36 alternate. The control levers 35, 36 are pivotally mounted on a bearing journal 37 which is fastened to the bearing element 6 and 7, respectively. An arm 38 protrudes outward from the control levers 35, 36 between its bearing point defined by the bearing pin 37 and the bearing point for the pivot pins 32, 33 of the collecting conveyor 8, which arm carries a control roller 39 at its end. This control roller engages in a guide groove 40 of a cam 41 or 42 designed as a link. The two control cams 41, 42 are arranged on the outside of the bearing elements 6, 7 and fastened to a frame 43 or 44, which is connected to the base plate 2. The control levers 35, 36 are now arranged such that they point forward in the direction of rotation A of the collecting drum 5, as can be seen in particular from FIG. 4.

Die beiden Steuerkurven 41,42 weisen drei aneinander anschliessende Abschnitte 45, 46 und 47 auf (Fig. 4). Der erste Abschnitt 45 der Steuerkurven 41, 42 ist kreisbogenförmig ausgebildet und verläuft koaxial zur Drehachse 4a. Dieser erste Abschnitt 45 geht, in Drehrichtung A der Sammeltrommel 5 gesehen, etwa an der mit F bezeichneten Stelle in den zweiten Abschnitt 47 über, dessen Abstand zur Umlaufachse 4a, in Drehrichtung A gesehen, immer kleiner wird. Der dritte Abschnitt 47 der Steuerkurven 41,42 beginnt etwa an der mit G bezeichneten Stelle und geht etwa an der Stelle H in den ersten Abschnitt 45 über. In Drehrichtung A gesehen, nimmt der Abstand des dritten Steuerkurvenabschnittes 47 von der Umlaufachse 4a von der Übergangsstelle G an zu.The two control cams 41, 42 have three adjoining sections 45, 46 and 47 (FIG. 4). The first section 45 of the control cams 41, 42 is designed in the form of a circular arc and extends coaxially with the axis of rotation 4a. This first section 45, viewed in the direction of rotation A of the collecting drum 5, merges approximately at the point denoted by F into the second section 47, the distance to the axis of rotation 4a of which, viewed in the direction of rotation A, becomes smaller and smaller. The third section 47 of the control curves 41, 42 begins approximately at the point designated by G. and merges into the first section 45 approximately at point H. Viewed in the direction of rotation A, the distance of the third cam section 47 from the circumferential axis 4a from the transition point G increases.

Durch diese Ausbildung der Steuerkurven 41, 42 wird bewirkt, dass während des Umlaufens der Sammelförderer 8 in Richtung des Pfeiles A die Steuerhebel 35, 36 im Uhrzeigersinn nach einwärts gegen die Umlaufachse 4a verschwenkt werden, sobald deren Steuerrollen 39 die Stelle F passiert haben. Damit werden auch die Sammelförderer 8 nach einwärts verschwenkt, was bei gegebener Drehzahl der Sammeltrommel 5 wegen des kleineren Abstandes von der Drehachse 4a eine Verminderung der Umlaufgeschwindigkeit der Sammelförderer 8 zur Folge hat. Im weiteren wird der Abstand zwischen jeweils benachbarten Sammelförderern 8 vergrössert, wobei der grösste Abstand in Fig. 4 mit a bezeichnet ist. Sobald die Steuerhebel 35, 36 mit ihren Steuerrollen 38 an der Übergangsstelle G vorbeilaufen, beginnen sich die Steuerhebel 35, 36 im Gegenuhrzeigersinn wieder nach aussen von der Drehachse 4a weg zu verschwenken. Das hat nun wiederum zur Folge, dass der Abstand der Sammelförderer 8 von der Drehachse 4a wieder grösser wird und die Umlaufgeschwindigkeit der Sammelförderer 8 wieder zunimmt. Zugleich verändert sich auch der Abstand zwischen benachbartzen Sammelförderern 8. Mit b ist der kleinste Abstand eingezeichnet. Währenddem die Steuerrollen 39 den ersten Steuerkurvenabschnitt 45 durchlaufen, bewegen sich die Sammelförderer 8 mit im wesentlichen konstanter Geschwindigkeit um die Umlaufachse 4a herum.This design of the control cams 41, 42 causes the control levers 35, 36 to be pivoted clockwise inward against the rotation axis 4a as the control rollers 39 have passed point F during the rotation of the collecting conveyor 8 in the direction of arrow A. The collecting conveyors 8 are thus also pivoted inwards, which, at a given speed of the collecting drum 5, results in a reduction in the rotational speed of the collecting conveyors 8 because of the smaller distance from the axis of rotation 4a. Furthermore, the distance between adjacent collecting conveyors 8 is increased, the greatest distance being designated by a in FIG. 4. As soon as the control levers 35, 36 with their control rollers 38 pass the transition point G, the control levers 35, 36 begin to pivot counterclockwise again outwards from the axis of rotation 4a. This in turn has the consequence that the distance of the collecting conveyors 8 from the axis of rotation 4a increases again and the rotational speed of the collecting conveyors 8 increases again. At the same time, the distance between adjacent collecting conveyors 8 also changes. The smallest distance is shown with b. While the control rollers 39 pass through the first cam section 45, the collecting conveyors 8 move around the revolving axis 4a at a substantially constant speed.

Die Übergangsstelle G befindet sich etwa im Übergangsbereich 13a (bzw. 14a, 15a), in welchem, wie anhand der Fig. 1 und 2 beschrieben, die Druckbogen 16, 17, 18 auf die Sammelförderer 8 aufgelegt werden. Durch die beschriebene Ausbildung der Steuerkurven 41, 42 entspricht der Abstand zwischen benachbarten Sammelförderern 8 in diesem Übergabebereich 13a etwa dem Abstand der Druckbogen 16, 17, 18 in der ankommenden Schuppenformation. Dieser Schuppenabstand entspricht etwa dem kleinsten Abstand b zwischen aufeinanderfolgenden Sammelförderern 8. Dadurch wird ein einwandfreies Übernehmen der zugeführten Druckbogen 16, 17, 18 durch die Sammelförderer 8 sichergestellt. Hiezu trägt weiter der Umstand bei, dass, wie erwähnt, die Umlaufgeschwindigkeit der Sammelförderer 8 in diesem Übergabebereich 13a herabgesetzt ist. Ausserhalb dieses Übergabebereiches 13a ist der Abstand zwischen benachbarten Sammelförderern 8 grösser, was es den Sammelförderern 8 ermöglicht, sich an den beiden äussersten seitlichen Punkten (in Fig. 4 links und rechts) ungestört aneinander vorbeizubewegen.The transition point G is located approximately in the transition region 13a (or 14a, 15a), in which, as described with reference to FIGS. 1 and 2, the printed sheets 16, 17, 18 are placed on the collecting conveyor 8. Due to the described design of the control cams 41, 42, the distance between adjacent collecting conveyors 8 in this transfer area 13a corresponds approximately to the distance between the printed sheets 16, 17, 18 in the incoming scale formation. This scale spacing corresponds approximately to the smallest distance b between successive collecting conveyors 8. This ensures that the supplied conveyors 16, 17, 18 are correctly taken over by the collecting conveyors 8. The fact that, as mentioned, the rotational speed of the collecting conveyors 8 in this transfer area 13a is reduced further contributes to this. Outside this transfer area 13a, the distance between adjacent collecting conveyors 8 is greater, which enables the collecting conveyors 8 to move past one another undisturbed at the two outermost lateral points (left and right in FIG. 4).

Die Sammelförderer 8 werden auf nachfolgend zu beschreibende Weise während ihres Umlaufes um die Umlaufachse 4a derart um ihre Drehachse 34 gedreht, dass sie ihre vertikale Stellung beibehalten mit ihrem First 8a stets nach oben weisen. Zu diesem Zwecke sind in den Lagerelementen 6, 7 Antriebswellen 49 drehbar gelagert, die um die Umlaufachse 4a herum angeordnet sind. Auf der Seite der Lagerscheibe 7 sitzen auf diesen Antriebswellen 49 zwei Kettenräder 50, 51. Die Kettenräder 50, 51 jeweils benachbarter Antriebswellen 49 sind mittels Ketten 52 miteinander verbunden, wobei die Antriebswellen 49 in zwei voneinander getrennte Gruppen unterteilt sind, wie das aus Fig. 4 hervorgeht. Eines der beiden auf den mit 49' und 49" bezeichneten Antriebswellen sitzenden Kettenräder 50, 51 steht über eine Kette 53 mit einem Kettenrad 54 in Verbindung, das koaxial zur Umlaufachse 4a ortsfest, d.h. nicht drehend, angeordnet ist. Durch das Abwälzen der Ketten 53 auf den Kettenrädern 54 werden die Antriebswellen 49' und 49" in Drehung versetzt. Diese Drehung wird über die Ketten 52 auf die Antriebswellen 49 der zugeordneten Gruppe übertragen.The collecting conveyors 8 are rotated in the manner to be described below during their rotation around the rotation axis 4a about their axis of rotation 34 such that they keep their vertical position with their ridge 8a always pointing upwards. For this purpose, drive shafts 49 are rotatably mounted in the bearing elements 6, 7 and are arranged around the circumferential axis 4a. On the side of the bearing disc 7, two sprockets 50, 51 sit on these drive shafts 49. The sprockets 50, 51 of adjacent drive shafts 49 are connected to one another by chains 52, the drive shafts 49 being divided into two separate groups, as shown in FIG. 4 emerges. One of the two sprockets 50, 51 seated on the drive shafts designated 49 'and 49 "is connected via a chain 53 to a sprocket 54 which is arranged coaxially to the rotational axis 4a in a fixed position, ie not rotating. By rolling the chains 53 on the chain wheels 54, the drive shafts 49 'and 49 "are rotated. This rotation is transmitted via the chains 52 to the drive shafts 49 of the assigned group.

Auf den Antriebswellen 49 sitzen zwei Kettenräder 55 und 56, die auf sich bezüglich der Sammelförderer 8 gegenüberliegenden Seiten angeordnet sind, wie das insbesondere aus Fig. 3 hervorgeht. Über diese Kettenräder 55, 56 sind Ketten 57 bzw. 58 geführt, die über Kettenräder 59 bzw. 60 verlaufen. Diese Kettenräder 59, 60 sitzen auf den Lagerzapfen 37 der geraden Steuerhebel 35. Benachbart zu den Kettenrädern 59, 60 sitzen auf diesen Lagerzapfen 37 weitere Kettenräder 61 bzw. 62, welche über Ketten 63 bzw. 64 mit Kettenrädern 65, 66 antriebsverbunden sind, die auf den Drehzapfen 32 bzw. 33 sitzen, mit denen die Sammelförderer 8 in den geraden Steuerhebeln 35 gelagert sind. Die Antriebsverbindung von den Antriebswellen 49 zu den Sammelförderern 8 erfolgt somit nur über die geraden Steuerhebel 35, wie das aus Fig. 3 hervorgeht.On the drive shafts 49 there are two chain wheels 55 and 56, which are arranged on opposite sides with respect to the collecting conveyor 8, as can be seen in particular from FIG. 3. Chains 57 and 58 are guided over these sprockets 55, 56 and run over sprockets 59 and 60, respectively. These sprockets 59, 60 are seated on the journals 37 of the straight control lever 35. Adjacent to the sprockets 59, 60 are seated on these journals 37, further sprockets 61 and 62, which are drive-connected to the sprockets 65, 66 via chains 63 and 64, respectively sit on the pivot 32 and 33, with which the collecting conveyor 8 are mounted in the straight control levers 35. The drive connection from the drive shafts 49 to the collecting conveyors 8 is thus only via the straight control lever 35, as can be seen in FIG. 3.

Durch die beschriebene Antriebsverbindung werden die Sammelförderer 8 während ihres Umlaufens um die Drehachse 4a im Gegenuhrzeigersinn, d.h. in Richtung des Pfeiles I (Fig. 4), um ihre Drehachse 34 gedreht, so dass sie ihre vertikale Lage beibehalten.By means of the drive connection described, the collecting conveyors 8 are turned counterclockwise during their rotation around the axis of rotation 4a, i.e. in the direction of arrow I (Fig. 4), rotated about its axis of rotation 34 so that they maintain their vertical position.

Der Antrieb der Förderanordnungen der Sammelförderer 8 erfolgt vorzugsweise durch die beschriebene Relativdrehung der Sammelförderer 8 bezüglich der Steuerhebel 35, 36, wie das in der Schweizer Patentanmeldung Nr. 2828/85 näher beschrieben ist. Die Vorschubgeschwindigkeit der Förderanordnungen wird somit von der Geschwindigkeit abgeleitet, mit der sich die Sammelförderer 8 um ihre Drehachse 34 drehen. Diese Drehgeschwindigkeit der Sammelförderer 8 ändert sich jedoch während des Durchlaufens des zweiten und dritten Abschnittes 46, 47 der Steuerkurven 41, 42 durch die zugeordneten Steuerrollen 39. Das hat dementsprechend zur Folge, dass auch die Vorschubgeschwindigkeit der Förderanordnungen der Sammelförderer 9 einer Änderung, d.h. einer Verlangsamung und anschliessenden Beschleunigung, unterworfen ist. Während des Förderns der Druckbogen 16, 17, 28 durch die Sammelförderer 8 mit reduzierter Geschwindigkeit können an diesen Druckbogen Verarbeitungsoperationen, wie Heften, Aufkleben einer Etikette und dergleichen, vorgenommen werden.The conveying arrangements of the collecting conveyors 8 are preferably driven by the described relative rotation of the collecting conveyors 8 with respect to the control levers 35, 36, as is described in more detail in the Swiss patent application No. 2828/85. The feed speed of the conveyor arrangements is thus derived from the speed at which the collecting conveyors 8 rotate about their axis of rotation 34. This rotational speed of the collecting conveyors 8, however, changes during the passage of the second and third sections 46, 47 of the control cams 41, 42 through the associated control rollers 39. This accordingly has the consequence that the feed speed of the conveying arrangements of the collecting conveyors 9 also changes, i.e. a slowdown and subsequent acceleration. While the printed sheets 16, 17, 28 are being conveyed by the collecting conveyors 8 at reduced speed, processing operations such as stapling, sticking on a label and the like can be carried out on these printed sheets.

Ergänzend zur vorangehenden Beschreibung, aus der die Wirkungsweise der Sammelvorrichtung 1 deutlich genug hervorgeht, sei noch darauf hingewiesen, dass durch das abwechslungsweise Vorsehen von geraden und abgekröpften Steuerhebeln 35, 36 letzteren ermöglicht wird, sich während des Einschwenkens gegen die Drehachse 4a aneinander vorbeizubewegen. In den Lagerelementen 6, 7 sind radiale, nach aussen offene Ausnehmungen 48 vorhanden, in die die Steuerrollen 39 tragenden Arme 38 der Steuerhebel 35, 36 während deren Einschwenkens nach einwärts eingreifen können, wie das aus Fig. 4 ersichtlich ist.In addition to the foregoing description, from which the mode of operation of the collecting device 1 is clear enough, it should also be pointed out that the alternate provision of straight and cranked control levers 35, 36 enables the latter to move during the on to pivot past each other against the axis of rotation 4a. In the bearing elements 6, 7 there are radial recesses 48 which are open to the outside and into which the arms 38 of the control levers 39, which carry the control rollers 39, can engage during their pivoting inwards, as can be seen from FIG. 4.

Im folgenden wird noch kurz auf einige der möglichen Varianten eingegangen.Some of the possible variants are briefly discussed below.

Es versteht sich, dass die Zuförderer 13, 14, 15 sowohl Einzeldruckbogen 16, 17, 18 wie auch mehrere, ineinanderliegende gefalzte Druckbogen zuführen können. Auch können mittig gefalzte Druckbogen, die keinen vorstehenden Randabschnitt aufweisen, verarbeitet werden, wobei das Öffnen dieser Druckbogen auf etwas andere als die beschriebene Weise erfolgen muss.It goes without saying that the feed conveyors 13, 14, 15 can feed both individual printed sheets 16, 17, 18 and also a plurality of folded printed sheets lying one inside the other. Center-folded printed sheets which do not have a protruding edge section can also be processed, it being necessary for these printed sheets to be opened in a different manner than that described.
