Abstract

Durch Zuförderer (22, 23, 24) werden Druckbogen (28, 30, 31) einzeln rittlings auf mit schiebenden Mitnehmern (33) versehene Sammelförderer (18) aufgelegt. Es sind mehrere, parallel zueinander verlaufende, in gleichmässigen Umfangsabständen voneinander um eine Umlaufachse (14) angeordnete und um diese umlaufende Sammelförderer (18) vorgesehen. Um schon während des Sammelns der Druckbogen eine deckungsgleiche Ausrichtung deren Kanten zu erreichen, sind im Bereich der Uebergabestelle jedes der Zuförderer (22, 23, 24) Anschlagelemente (35, 36, 37) angeordnet, um die Druckbogen (28, 30, 31) jeweils gegen den schiebendenen Mitnehmer (33) zu drängen.By means of feed conveyors (22, 23, 24), printed sheets (28, 30, 31) are placed astride individual collecting conveyors (18) provided with pushing drivers (33). A plurality of collecting conveyors (18) are provided which run parallel to one another and are arranged at uniform circumferential distances from one another about an axis of rotation (14) and revolve around them. In order to achieve a congruent alignment of their edges while the printed sheets are being collected, stop elements (35, 36, 37) are arranged in the area of the transfer point for each of the feed conveyors (22, 23, 24) in order to hold the printed sheets (28, 30, 31) to push against the pushing driver (33).

Description



Die vorliegende Erfindung betrifft eine Vorrichtung ge­mäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a device according to the preamble of patent claim 1.

Eine solche Einrichtung ist aus der DE-OS 36 20 945.7 oder aus der weitgehend inhaltsgleichen GB-OS 21 77 380 bekannt. Im Gegensatz zu anderen vorbekannten Sammel­einrichtungen (beispielsweise gemäss CH-PS 535.696 oder 650.729), die nur einen einzigen, in der Regel geradli­nigen Sammelförderer aufweisen, ist die vorbekannte Einrichtung imstande, pro Zeiteinheit erheblich mehr Druckbogen zusammenzutragen, weil jeder der Sammelför­derer auf dem Wege zwischen zwei benachbarten Zuförde­rern einen Umlauf um die Umlaufachse vollführt und sei­ne Mitnehmer während dieses Umlaufs um den Abstand zum nächsten Zuförderer vorgeschoben werden. Die Mitnehmer beschreiben somit - räumlich gesehen - eine wendelför­mige Bahn. Die Zuförderer können daher die gefalteten Druckbogen praktisch in derselben Anzahl pro Zeitein­heit heranführen, wie sie beispieslweise aus einer vor­geschalteten Druckerpresse anfallen. Die Mitnehmer kön­nen dabei verhältnismässig langsam, d.h. ohne Gefahr der Beschädigung der Druckbogen vorgeschoben werden.Such a device is known from DE-OS 36 20 945.7 or from GB-OS 21 77 380, which is largely identical in content. In contrast to other previously known collecting devices (for example according to CH-PS 535.696 or 650.729), which only have a single, generally linear collecting conveyor, the known device is able to collect considerably more printed sheets per unit of time, because each of the collecting conveyors on the way between makes two adjacent feeders orbits around the axis of rotation and its drivers are advanced by the distance to the next feeder during this rotation. In terms of space, the drivers therefore describe a helical path. The feeders can therefore feed the folded printed sheets in practically the same number per unit of time as they occur, for example, from an upstream printing press. The drivers can be relatively slow, i.e. can be fed without risk of damage to the printed sheets.

Allerdings ist bei der vorbekannten Einrichtung darauf zu achten, dass die Zuförderer die Druckbogen auf die vorbeilaufenden Sammelförderer so ablegen, dass sie jeweils vor einen der ankommenden, schiebenden Mitneh­mer aufzuliegen kommen. Dies ist nur möglich, wenn die die Zuförderer und die Sammelförderer so in bezug auf­ einander gesteuert und abgestimmt werden, dass die Druckbogen in einem, wenn auch kleinem Abstand, vor dem gerade ankommenden Mitnehmer des betreffenden Sammel­förderers zum aufliegen kommen, d.h. dass ein gewisser Abstand zwischen dem ankommenden Mitnehmer und der in Förderrichtung des Sammelförderers gesehen) nachlaufen­den Kante der Druckbogen eingehalten wird.However, in the case of the known device, care must be taken that the feed conveyors place the printed sheets on the passing conveyors in such a way that they come to rest in front of one of the arriving pushing drivers. This is only possible if the feed conveyors and the collective conveyors are so related are controlled and coordinated with one another so that the printed sheets come to rest, albeit at a small distance, in front of the just arriving driver of the collecting conveyor in question, i.e. that there is a certain distance between the incoming driver and the trailing edge of the printed sheets when viewed in the conveying direction of the collecting conveyor) is observed.

Für den jeweils ersten Druckbogen kann dies ohne Belang sein, wenn die Auflagestelle auf dem Sammelförderer sich nicht selbst bewegt, weil dieser erste Druckbogen dann auf dem betreffenden Sammelförderer nach der Abla­ge "stehen" bleibt, bis er vom entsprechenden, schie­benden Mitnehmer "eingeholt" und erst dann vorgeschoben wird. Für jeden weiteren Druckbogen aber, der auf einem zuvor abgelegten Bogen zu liegen kommt, ist dieser Ab­stand jedoch insofern von Bedeutung, dass jeder dieser weitere Druckbogen infolge des Reibschlusses mit dem darunterliegenden Druckbogen vom Moment der Auflage an vorgeschoben werden kann, ohne dass dieser weitere Druckbogen unmittelbar am schiebenden Mitnehmer an­liegt. Das Ergebnis ist, dass die Kanten der von den Sammelförderern zusammengetragen Druckbogen in bezug aufeinander nicht deckungsgleich ausgerichtet sind. Da­raus ergibt sich die Notwendigkeit, die auf den Sammel­förderern der bekannten Einrichtung zusammengetragenen Gruppen von Druckbogen vor der nächsten Operation, bei­spielsweise vor der Heftung, noch auszurichten.For the first printed sheet in each case this can be irrelevant if the support point on the collecting conveyor does not move itself because this first printed sheet then "remains" on the relevant collecting conveyor after being deposited until it is "caught up" by the corresponding pushing driver and only then is advanced. However, this distance is important for each additional printed sheet that comes to rest on a previously deposited sheet, in that each of these additional printed sheets can be pushed forward from the moment of the print due to the frictional engagement with the underlying printed sheet, without this additional printed sheet rests directly on the pushing driver. The result is that the edges of the printed sheets collected by the collecting conveyors are not aligned with each other. This results in the need to align the groups of printed sheets gathered on the collecting conveyors of the known device before the next operation, for example before the stapling.

Es ist daher als ein Zweck der Erfindung anzusehen, eine Einrichtung der eingangs genannten Art zu schaf­fen, die Gewähr dafür bietet, dass die an den Falz an­ grenzenden Kanten der auf den Sammelförderern zu Grup­pen zusammengetragenen Druckbogen in bezug aufeinander deckungsgleich ausgerichtet sind.It is therefore to be regarded as a purpose of the invention to provide a device of the type mentioned at the outset, which guarantees that the fold is attached bordering edges of the printed sheets brought together in groups on the collecting conveyors are aligned in relation to one another.

Dieser Zweck wird von der vorgeschlagenen Einrichtung gemäss der Erfindung dadurch erreicht, dass sie die Merkmale aufweist, die im Kennzeichen des Patentanspru­ches 1 umschrieben sind.This purpose is achieved by the proposed device according to the invention in that it has the features which are described in the characterizing part of patent claim 1.

Durch die in axialer Richtung im wesentlichen ortsfe­sten Anschläge wird ein Druckbogen an einem nur durch Reibschluss mit dem darunterliegenden Druckbogen be­dingten Vorschub gehindert und zurückgehalten, bis der schiebende Mitnehmer auch auf den zuletzt aufgelegten Druckbogen direkt auftrifft. Damit sind die Kanten der Druckbogen in bezug aufeinander deckungsgleich ausge­richtet.Due to the essentially stationary stops in the axial direction, a printed sheet is prevented and held back from a feed which is caused only by frictional engagement with the underlying printed sheet, until the pushing driver also directly hits the last printed sheet. The edges of the printed sheets are thus aligned with each other.

Merkmale bevorzugter Ausführungsformen der erfindungs­gemässen vorgeschlagenene Einrichtung sind in den ab­hängigen Ansprüchen umschrieben.Features of preferred embodiments of the proposed device according to the invention are described in the dependent claims.

Nachstehend ist die Erfindung rein beispielsweise an­hand der Zeichnung näher beschrieben. Es zeigt:

  • Fig. 2 wiederum schematisch eine Ansicht in Richtung der Umlaufachse eine Anzahl der Sammelförderer im Bereich einer Ueberga­bestelle eines der Zuförderer,
  • Fig. 3 eine vereinfachte Draufsicht auf Fig. 2, und
  • Fig. 4 einen vereinfachten Schnitt längs der Li­nie IV-IV der Fig. 2.
The invention is described in more detail below, for example, with reference to the drawing. It shows:
  • 1 in a simplified diagrammatic representation, a device for collecting printed sheets,
  • 2 again schematically shows a view in the direction of the axis of rotation of a number of collecting conveyors in the area of a transfer point of one of the feeding conveyors,
  • Fig. 3 is a simplified plan view of Fig. 2, and
  • 4 shows a simplified section along the line IV-IV of FIG. 2.

Der Aufbau der in Fig. 1 dargestellten Einrichtung 10 entspricht weitgehend dem Aufbau der in der bereits genannten DE-OS 36 20 945.7 bzw. GB-OS 21 77 380 be­schriebenen Einrichtung, auf welche Druckschriften hier ausdrücklich verwiesen wird. Die Einrichtung 10 weist einen Sockel 11 auf, an dessen beiden Enden je ein La­gerbock 12, 13 vorhanden ist. In den Lagerböcken 12, 13 ist eine Welle 14 drehbar gelagert, die sich über den Lagerbock 12 hinauserstreckt und dort ein aufgekeiltes Kettenrad 15 trägt. Zwischen den Lagerböcken 12, 13 sitzen auf den Endbereichen der Welle 14 zwei mit die­ser drehfeste Scheiben 16, 17. Im Umfangsbereich jeder der Scheiben 16, 17 sind die Enden von in gleichmässi­gen Umfangsabständen auf einem zur Welle 14 konzentri­schen Kreis angeordnete Sammelförderer 18 drehbar gela­gert. In Fig. 1 sind der besseren Uebersicht wegen nur fünf solcher Sammelförderer 18 sichtbar, während es in Wirklichkeit erheblich mehr sein können, wobei die Bo­genlänge zwischen benachbarten Sammelförderern 18 etwa 10-30 cm betragen kann.The structure of the device 10 shown in FIG. 1 largely corresponds to the structure of the device described in the aforementioned DE-OS 36 20 945.7 or GB-OS 21 77 380, to which publications are expressly referred. The device 10 has a base 11, at the two ends of which a bearing block 12, 13 is provided. In the bearing blocks 12, 13, a shaft 14 is rotatably supported, which extends beyond the bearing block 12 and carries a splined sprocket 15 there. Between the bearing blocks 12, 13 are seated on the end regions of the shaft 14 with two disks 16, 17 which are non-rotatable therewith. In the circumferential region of each of the disks 16, 17, the ends of collecting conveyors 18, which are arranged at uniform circumferential intervals, are rotatably mounted on a circle arranged concentrically with the shaft 14. In FIG. 1, for the sake of a better overview, only five such collecting conveyors 18 are visible, while in reality there may be considerably more, the arc length between adjacent collecting conveyors 18 being approximately 10-30 cm.

Es sind hier nicht dargestellte, aber in der bereits genannten DE-OS bzw. GB-OS eingehend beschriebene Mit­tel vorgesehen, die bewirken, dass alle Sammelförderer 18 (die in Fig. 1 der Einfachheit halber als Stangen dargestellt sind) stets unabhängig von ihrer Momentan­stellung dieselbe Orientierung haben.Means are not shown here, but are described in detail in the aforementioned DE-OS or GB-OS, which ensure that all collecting conveyors 18 (which are shown as bars in FIG. 1 for the sake of simplicity) are always independent of their current position have the same orientation.

Die Welle 14 und damit die Scheiben 16, 17 sind von einem Getriebemotor 19 über eine Kette und das Ketten­rad 15 im Sinne des Pfeiles 21 angetrieben, so dass je­der der Sammelförderer 18 auf einer Kreisbahn um die Welle 14 umläuft.The shaft 14 and thus the disks 16, 17 are driven by a geared motor 19 via a chain and the sprocket 15 in the direction of the arrow 21, so that each of the collecting conveyors 18 rotates in a circular path around the shaft 14.

In Fig. 1 gehören zur Einrichtung drei Zuförderer 22, 23, 24 und ein Wegförderer 25. Die Zuförderer 22-24 sind mit gesteuerten Greifern 26 versehen, und der Weg­förderer 25 ebenfalls mit gesteuerten Greifern 27. Der Zuförderer führt gefaltete Druckbogen 28 in hängender Lage im Sinne des Pfeiles 29 heran, in dem jeder seiner Greifer 26 einen der Druckbogen 28 an seinem Falz er­fasst. Auf ähnliche Weise führt der Zuförderer 23 ge­faltete Druckbogen 30 heran und der Zuförderer 24 ge­faltete Druckbogen 31.In Fig. 1, the device includes three feed conveyors 22, 23, 24 and a removal conveyor 25. The feed conveyors 22-24 are provided with controlled grippers 26, and the removal conveyor 25 also with controlled grippers 27. The feed conveyor guides folded printed sheets 28 in a hanging position in the direction of arrow 29, in which each of its grippers 26 engages one of the printed sheets 28 on its fold. In a similar manner, the feed conveyor 23 feeds folded printed sheets 30 and the feed conveyor 24 folds printed sheets 31.

In den Abgabebereichen der Zuförderer 22-24 werden die Druckbogen 28, 30, 31 durch in Fig. 1 nicht näher dar­gestellte Mittel geöffent, wonach die Greifer 26 geöff­net werden, so dass die Druckbogen rittlings zum Auf­liegen auf einen der Sammelförderer 18 gelangen.In the delivery areas of the feed conveyors 22-24, the printed sheets 28, 30, 31 are opened by means not shown in FIG. 1, after which the grippers 26 are opened so that the printed sheets astride one of the collecting conveyors 18.

Analog ergreift der Wegförderer 25 mit seinem Greifern 27 am Ende jedes der Sammelförderer 18 das aus je einem der ineinandergelegten Druckbogen 28, 30, 31 bestehende Fertigprodukt P und befördert dieses ebenfalls hängend und im Sinne des Pfeiles 32 zu einer weiteren Verarbei­tungsstation, beispielsweise zu einer Bindemaschine oder einer Heftmaschine.Analogously, the away conveyor 25 grips with its grippers 27 at the end of each of the collecting conveyors 18 the finished product P, which consists of one of the interlaced printed sheets 28, 30, 31, and also conveys it hanging and in the direction of arrow 32 to a further processing station, for example to a binding machine or a stapler.

In jedem der Sammelförderer 18 ist ein Fördermechanis­mus eingebaut, der mit in regelmässigen Abständen von­einander angeordneten Mitnehmern 33 versehen ist. Der Fördermechanismus und dessen Antrieb ist in den genann­ten DE-OS bzw. GB-OS eingehend beschrieben. Die Mitneh­mer 33 bewegen sich kontinuierlich in Richtung des Pfeiles 34, d.h. in Fig. 1 von links nach rechts.A conveying mechanism is installed in each of the collecting conveyors 18 and is provided with drivers 33 arranged at regular intervals from one another. The conveyor mechanism and its drive is described in detail in the aforementioned DE-OS and GB-OS. The drivers 33 move continuously in the direction of arrow 34, i.e. 1 from left to right.

Die Fördergeschwindigkeit der Zuförderer 22, 23, 24 und die gegenseitigen Abstände der Greifer 26 sind derart auf die Umlaufgeschwindigkeit der Sammelförderer 18 und deren gegenseitigen Umfangsabstand abgestimmt, dass stets ein Sammelförderer 18 im wesentlichen unter einem der Greifer 26 ist, wenn dieser geöffnet wird. Ferner ist die Vorschubgeschwindigkeit der Mitnehmer 33 und die Abstände der Zuförderer 22, 23, 24 voneinander so aufeinander abgestimmt, dass jeder Mitnehmer 33 während eines Umlaufes des entsprechenden Sammelförderers 18 um einen dem Abstand der Zuförderer 22, 23, 24 voneinander entsprechenden Weg vorgeschoben wird.The conveying speed of the feed conveyors 22, 23, 24 and the mutual spacing of the grippers 26 are matched to the rotational speed of the collecting conveyors 18 and their mutual circumferential spacing such that a collecting conveyor 18 is always substantially below one of the grippers 26 when it is opened. Furthermore, the feed speed of the carriers 33 and the distances between the feed conveyors 22, 23, 24 are coordinated with one another such that each carrier 33 is advanced during a revolution of the corresponding collecting conveyor 18 by a distance corresponding to the distance of the feed conveyors 22, 23, 24 from each other.

Soweit die Gemeinsamkeiten mit der in der genannten DE-OS bzw. GB-OS beschriebenen Einrichtung. Bei der vorliegenden Einrichtung 10 sind im Uebergabebereich jedes der Zuförderer 22, 23, 24 Anschlagelemente 35, 36, 37 angeordnet, die alle im wesentlichen gleich aus­gebildet sind. Diese Anschlagelemente und deren Wirkung sind nachstehend anhand der Fig. 2 - 4 beschrieben, in denen der Uebergabebereich des Zuförderers 23 um das zugeordnete Anschlagelement 36 dargestellt sind.As far as the similarities with the facility described in the aforementioned DE-OS or GB-OS. In the The present device 10 are arranged in the transfer area of each of the feed conveyors 22, 23, 24 stop elements 35, 36, 37, all of which are essentially of the same design. These stop elements and their effect are described below with reference to FIGS. 2-4, in which the transfer area of the feed conveyor 23 around the associated stop element 36 is shown.

Nur angedeutet ist in Fig. 2 der Zuförderer 23 und zwei seiner Greifer 26, die je eines der Druckbogen 30 im Sinne des Pfeiles 29 heranführen. Zu bemerken ist an dieser Stelle, dass die Bogen 28, 30 und 31 mit "Vor­falz" gefaltet sind, d.h. der eine (hier der nachlau­fende) vom Falz ausgehende Teil des Bogens ist länger als der andere. Eine dem Uebergabebereich des Zuförde­rers 23 zugeordnete Oeffnungsvorrichtung ist mit 38 bezeichnet. Diese weist eine Anzahl in gleichen gegen­seitigen Abständen wie die Greifer 26 voneinander ange­ordnete, im Sinne des Pfeiles 39 etwa mit derselben Ge­schwindigkeit wie die Greifer 26 umlaufende, nach hin­ten offene Haken auf, in die der längere, (nachlaufen­de) Teil jeweils eines Druckbogens mit seiner dem Falz gegenüberliegenden Kante einläuft, wodurch der Bogen 30 unter Bildung eines etwa keilförmigen Oeffnungsspaltes 41 geöffnet wird (Fig. 2 links). In diesen Spalt dringt der in Fig. 2 ganz links erscheinende und im Sinne des Pfeiles 21 umlaufende Sammelförderer 18, auf dem bereits ein Druckbogen 28 aufliegt. Der Druckbogen 30 auf den zweiten von links dargestellten Sammelförderer 18 wird vom Greifer 26 gerade fallengelassen.The feed conveyor 23 and two of its grippers 26, each of which feeds one of the printed sheets 30 in the direction of the arrow 29, are only indicated in FIG. 2. It should be noted at this point that sheets 28, 30 and 31 are folded with a "pre-fold", ie one part (here the trailing part) of the sheet starting from the fold is longer than the other. An opening device assigned to the transfer area of the feed conveyor 23 is designated by 38. This has a number of hooks which are arranged at the same mutual spacing as the grippers 26 and which, in the direction of arrow 39, rotate at about the same speed as the grippers 26 and open to the rear, into which the longer, (trailing) part of each of a printing sheet with its the edge opposite the fold runs in, whereby the sheet 30 is opened to form an approximately wedge-shaped opening gap 41 (FIG. 2 on the left). The collecting conveyor 18 appearing on the far left in FIG. 2 and rotating in the direction of arrow 21, on which a printed sheet 28 already lies, penetrates into this gap. The printed sheet 30 on the second collecting conveyor 18 shown from the left is just dropped by the gripper 26.

Das Anschlagelement 36 besteht im wesentlichen aus einem ebenen Blechteil 42. An der Rückseite dieses Blechteils 42 ist ein mit zwei abstehenden Zapfen 43 versehenes Balkenstück 44 befestigt. An den Zapfen 43 ist je das eine Ende einer von zwei parallelen und gleich langen Pendelschwingen 45 angelenkt, deren ande­re Enden schwenkbar sowie axial verstellbar und fest­stellbar auf je einem Wellenstummel 46 gelagert sind. Diese Verstellbarkeit der Anschlagelemente längs der Wellenstummel 46 dient dazu, die Einrichtung an ver­schiedene Formate der zusammenzutragenden Druckbogen anzupassen. Die Wellenstummel 46 gehen von einem Ausle­ger 47 aus, der seinerseits seitlich von einem zur Wel­le 14 parallelen, die gesamte Einrichtung überspannen­den Träger 48 abstehen.The stop element 36 essentially consists of a flat sheet metal part 42. On the rear side of this sheet metal part 42, a beam piece 44 provided with two protruding pins 43 is fastened. One end of one of two parallel and equally long pendulum rockers 45 is articulated to the pin 43, the other ends of which are pivotable and axially adjustable and lockable on a respective shaft end 46. This adjustability of the stop elements along the stub shaft 46 serves to adapt the device to different formats of the printed sheets to be gathered. The shaft ends 46 start from a cantilever 47, which in turn protrudes laterally from a carrier 48 parallel to the shaft 14 and spanning the entire device.

Die den Sammelförderern 18 zugekehrte untere Kante 49 des Blechteiles 42 ist entsprechend der kreisförmigen Umlaufbahn der Sammelförderer 18 gekrümmt. Wenn ge­wünscht, kann das pendelfähig aufgehängte Blechteil 42 mit seiner unteren Kante 49 den Scheitel von mehreren Sammelförderern 18 berühren. Falls die untere Kante 49 des Blechteiles 42 die Sammelförderer 18 nicht berühren soll, kann eine in Fig. 2 nur liniert angedeutete, ver­stellbare und feststellbare Anschlaganordnung 50 vorge­sehen sein, mit der sich der radiale Minimalabstand der unteren Kante 49 des Blechteils 42 von der Umlaufbahn der Sammelförderer 18 einstellen lässt. Das Blechteil 42 bleibt aber in Umlaufrichtung (Pfeil 21) der Sammel­förderer 18 auslenkbar.The lower edge 49 of the sheet metal part 42 facing the collecting conveyors 18 is curved in accordance with the circular orbit of the collecting conveyors 18. If desired, the pendulously suspended sheet metal part 42 can touch the apex of several collecting conveyors 18 with its lower edge 49. If the lower edge 49 of the sheet metal part 42 should not touch the collecting conveyor 18, an adjustable and ascertainable stop arrangement 50, indicated only in a lined manner in FIG. 2, can be provided, with which the radial minimum distance of the lower edge 49 of the sheet metal part 42 from the orbit of the Collective conveyor 18 can be set. The sheet metal part 42 remains deflectable in the direction of rotation (arrow 21) of the collecting conveyor 18.

Nachstehend soll anhand Fig. 3 die Funktionsweise be­schreiben werden. Dabei sind die sechs Sammelförderer 18, die in Fig. 2 erscheinen, unter Weglassung des Zu­förderers 23 und der Oeffungsvorrichtung 38 darge­stellt. In Fig. 3 sind von links nach rechts die ver­schiedenen Phasen deutlich sichtbar. Auf dem ersten Sammelförderer 18 liegt erst ein Druckbogen 28 auf, der vom zugeordneten Mitnehmer 33 in Richtung des Pfeiles 34 vorgeschoben wird. Auf den zweiten Sammelförderer fällt in einem Absstand d vor dem Mitnehmer ein Druck­bogen 30 auf den schon vorhandenen und vom entsprechen­den Mitnehmer 33 vorgeschobenen Druckbogen 28. Dieser neue Druckbogen 30 wird vom Moment des Aufliegens auf dem Druckbogen 28 durch Reibschluss mit diesem sofort in Richtung des Pfeiles 34 vorgeschoben , wobei zu­nächst der Abstand d bestehen bleibt. Dies ist in Fig. 3 am dritten und vierten Sammelförderer von links deut­lich zu erkennen. Der Druckbogen 30 auf dem vierten Sammelförderer trifft nun auf das Anschlagelement 36 auf und wird von diesem an einer weiteren, durch Reib­schluss bedingten Vorschubbewegung gehindert, während der darunterliegende Druckbogen 28 weiter vorgeschoben wird. Wenn endlich der Mitnehmer 33 sich auf einen dem Format der Druckbogen entsprechenden Abstand dem An­schlagelement genähert hat (in Fig. 3 fünfter Sammel­förderer von links) sind die Druckbogen 28 (nicht mehr sichtbar) und 30 deckungsgleich ausgerichtet und pas­sieren gleichzeitig das Ende des Anschlagelementes 36.The mode of operation will be described below with reference to FIG. 3. The six collecting conveyors 18, which appear in FIG. 2, are shown with the omission of the feed conveyor 23 and the opening device 38. In Fig. 3 the different phases are clearly visible from left to right. On the first collecting conveyor 18 there is only a printed sheet 28 which is pushed in the direction of arrow 34 by the associated driver 33. On the second collecting conveyor, at a distance d in front of the driver, a printing sheet 30 falls on the printing sheet 28 already present and advanced by the corresponding driver 33. This new printing sheet 30 is immediately frictionally attached to the printing sheet 28 in the direction of the arrow 34 advanced, initially maintaining the distance d. This can be clearly seen in Fig. 3 from the third and fourth collecting conveyor from the left. The printed sheet 30 on the fourth collecting conveyor now strikes the stop element 36 and is prevented from this by a further feed movement caused by frictional engagement, while the underlying printed sheet 28 is advanced further. When the driver 33 has finally approached the stop element at a distance corresponding to the format of the printed sheets (fifth collecting conveyor from the left in FIG. 3), the printed sheets 28 (no longer visible) and 30 are aligned and at the same time pass the end of the stop element 36.

Weil bei diesem Ausführungsbeispiel die Stellung der in Umlaufrichtung gesehenen Endkante 51 des Blechteiles 42 bei einer Verstellung des radialen Abstandes der unte­ ren Kante 49 von der Umlaufbahn der Sammelförderer 18 sich in Umlaufrichtung verändert, kann es nützlich sein, den Endbereich 52 (Fig. 2) des Anschlagelementes aus einem elastisch biegsamen Material, beispielsweise aus einem Gummiblatt oder bestehend aus einer Borsten­reihe auszubilden, so dass dieser Endbereich 52 unter elastischer Verbiegung durch die nun deckungsgleich ausgerichteten Druckbogen 28, 30 unterfahren werden kann, ohne dass die Druckbogen gestaucht würden.Because in this embodiment, the position of the end edge 51 of the sheet metal part 42 seen in the circumferential direction when the radial distance of the bottom is adjusted Ren edge 49 of the orbit of the collecting conveyor 18 changes in the circumferential direction, it may be useful to form the end region 52 (FIG. 2) of the stop element from an elastically flexible material, for example from a rubber sheet or consisting of a row of bristles, so that this end region 52 can be passed under with elastic bending by the now congruently aligned printed sheets 28, 30 without the printed sheets being compressed.

Aus Fig. 4 ist ersichtlich, dass jeder Sammelförderer 18 eine Kette 53 aufweist, die in einer Führungsschiene 54 (Fig. 2) geführt ist und an welcher die in regelmäs­sigen, gegenseitigen Abständen angeordneten und nach oben abstehenden Mitnehmer 33 befestigt sind. Eine An­zahl der jedem der Mitnehmer 33 vorangehenden Glieder der Kette 53 ist auch mit je einem Auflageelement 55 in der Form eines Satteldaches versehen. Bei diesem Aus­führungsbeispiel bewegt sich also auch die Auflageflä­che der Sammelförderer gemeinsam mit den Mitnehmern.It can be seen from FIG. 4 that each collecting conveyor 18 has a chain 53 which is guided in a guide rail 54 (FIG. 2) and to which the drivers 33 which are arranged at regular, mutually spaced intervals and protrude upwards are fastened. A number of the links of the chain 53 preceding each of the drivers 33 are also each provided with a support element 55 in the form of a saddle roof. In this exemplary embodiment, the support surface of the collecting conveyors also moves together with the drivers.
