Abstract

An outfeed conveyor is arranged beneath a rotary bucket wheel driven to rotate in a predetermined rotational direction. A belt conveyor is arranged downstream of, and a product entrainment arrangement is arranged upstream of, the outfeed conveyor. An endless revolving belt is guided about belt rolls of the outfeed conveyor and upon which come to bear the printed products in inbricated formation. Entrainment elements of the product entrainment arrangement completely stuff the printed products into the pockets of the bucket wheel. Upon ejection of the printed products out of the bucket wheel they are fixedly clamped at their trailing edges between a support element and extensions or cantilever arms of the entrainment elements until the entrainment elements have passed the support element and thus an intersection location between the entrainment elements and the support element. The resiliently arranged extensions of the entrainment elements are pivoted by the support element in a predetermined direction, such as clockwise, so that the printed products are cyclically released. There is thus formed an inbricated formation of the printed products within which all prnited products are aligned and there can be maintained a substantially constant mutual spacing between the individual printed products.

Description

Die vorliegende Erfindung betrifft ein Verfahren bzw. eine Vorrichtung zum Uebernehmen von Druckereierzeugnissen von einem umlaufend angetriebenen Schaufelrad nach dem Oberbegriff des Anspruches 1 bzw. 3.3. The present invention relates to a method and an apparatus for taking over printed products from a rotatingly driven impeller according to the preamble of claims 1 and 3 respectively.

Eine Vorrichtung dieser Art ist beispielsweise aus der EP-OS 0067399 bekannt. Bei dieser Vorrichtung laufen paarweise an zwei parallel und synchron umlaufenden Trägern angeordnete Mitnehmer auf die nachlaufenden Kanten der Druckereierzeugnisse auf, sobald die vorlaufenden Kanten dieser Druckereierzeugnisse von den Taschen des Schaufelrades freigegeben worden sind, und richten somit die nachlaufenden Kanten der Druckereierzeugnisse rechtwinklig zur Förderrichtung des Wegförderers aus. Beim Einschiessen der Druckereierzeugnisse in die Taschen des Schaufelrades kann es vorkommen, dass diese verkanten. Die Druckereierzeugnisse fallen im freien Fall aus den Taschen und werden von den bereits auf den Wegförderer aufgelegten Druckereierzeugnissen und den Bändern des Wegförderers infolge Reibung mitgenommen. Somit ist es vor allem bei verkanteten Druckereierzeugnissen möglich, dass eine vorlaufende Ecke von Aushebebändern erfasst wird, bevor die Mitnehmer auf die nachlaufende Kante des verkanteten Druckereierzeugnisses richtend einwirken konnten. Weiter können Druckereierzeugnisse auf dem freien Fallweg zwischen dem Schaufelrad und dem Wegförderer bzw. den Trägern der Mitnehmer durch Wind des Schaufelrades oder Flattern der nachlaufenden Kanten unkontrolliert beeinflusst werden, was auch zur Folge haben kann, dass die Abstände zwischen einzelnen Druckereierzeugnissen in der weggeführten Schuppenformation ungleichmässig sein können und dass einzelne Druckereierzeugnisse in der Schuppenformation verkantet angeordnet sind. Insbesondere können auch Aenderungen in der Rotationsgeschwindigkeit des Schaufelrades zu Phasenverschiebungen führen, die ungleichmässige Abstände zwischen den Druckereierzeugnissen zur Folge haben.A device of this type is known for example from EP-OS 0067399. In the case of this device, drivers arranged in pairs on two parallel and synchronously rotating carriers run onto the trailing edges of the printed products as soon as the leading edges of these printed products have been released from the pockets of the paddle wheel, and thus align the trailing edges of the printed products at right angles to the conveying direction of the conveyor out. When the printed products are shot into the pockets of the paddle wheel, they may tilt. The printed products fall out of their pockets in free fall and are carried along by the printed products already placed on the conveyor and the belts of the conveyor due to friction. It is therefore possible, especially in the case of jammed printed products, for a leading corner to be picked up by lifting belts before the drivers could act on the trailing edge of the jammed printed product. Furthermore, printed products on the free fall path between the paddle wheel and the conveyor or the carriers of the driver by the wind Paddle wheel or fluttering of the trailing edges can be influenced in an uncontrolled manner, which can also have the consequence that the distances between individual printed products in the removed scale formation can be uneven and that individual printed products are canted in the scale formation. In particular, changes in the rotational speed of the paddle wheel can also lead to phase shifts, which result in uneven spacing between the printed products.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bzw. eine Vorrichtung zum Uebernehmen von Druckereierzeugnissen von einem umlaufend angetriebenen Schaufelrad einer Druckereimaschine vorzuschlagen, bei dem bzw. der auch verkantet oder nicht ganz in das Schaufelrad eingeschossene Druckereierzeugnisse mit Sicherheit beim bilden der Schuppenformation ausgerichtet werden, und bei welchem bzw. welcher der durch das Schaufelrad erzeugte Luftzug keinen unkontrollierten Einfluss auf die Druckereierzeugnisse ausüben kann.The object of the present invention is to propose a method and a device for taking over printed products from a rotating driven paddle wheel of a printing machine, in which printed products which are also tilted or not completely shot into the paddle wheel are reliably aligned when forming the scale formation, and at which or which the air draft generated by the paddle wheel cannot exert an uncontrolled influence on the printed products.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 bzw. 3 gelöst.This object is solved by the features of the characterizing part of claims 1 and 3, respectively.

Die Druckereierzeugnisse werden an der Kreuzungsstelle der Bewegungsbahn der Mitnehmer und der Transportebene des Wegförderers kurzzeitig festgehalten, bis die Mitnehmer die Kreuzungsstelle passiert haben. Somit können die Druckereierzeugnisse nur im Takt der Freigabe durch die Mitnehmer vom Wegförderer wegtransportiert werden. Damit wird ein genauer Abstand der Druckereierzeugnisse sowie ein genaues Ausrichten der nachlaufenden Kante quer zur Förderrichtung des Wegförderers erzwungen.The printed products are briefly held at the intersection of the movement path of the drivers and the transport level of the conveyor, until the drivers have passed the intersection. This means that the printed products can only be transported away from the conveyor by the drivers. This will give an exact distance of the printed products as well as a precise alignment of the trailing edge transversely to the conveying direction of the conveyor.

In einer bevorzugten Ausführungsform werden die Druckereierzeugnisse an der Kreuzungsstelle zwischen den Mitnehmern und einem Auflageorgan festgeklemmt und die Mitnehmer werden mittels dem Auflageorgan ausser Eingriff mit den Druckereierzeugnissen gebracht. Dies erlaubt, in einfacher Weise ein schonendes Festklemmen und wieder Freigeben der Druckereierzeugnisse.In a preferred embodiment, the printed products are clamped at the intersection between the drivers and a support member and the drivers are disengaged from the printed products by means of the support member. This allows gentle clamping and releasing of the printed products in a simple manner.

In einer weiteren bevorzugten Ausführungsform greifen die Mitnehmer vor der Kreuzungsstelle in die Taschen des Schaufelrades ein, um vorstehende Druckereierzeugnisse in die Taschen hineinzustossen. Dadurch wird sichergestellt, dass die Druckereierzeugnisse ganz in die Taschen eingestossen sind, und die nachlaufenden Kanten bereits ausgerichtet auf dem Auflageorgan zur Auflage kommen. Insbesondere wird ein Flattern der nachlaufenden Kanten verhindert.In a further preferred embodiment, the drivers engage in the pockets of the paddle wheel in front of the crossing point in order to push protruding printed products into the pockets. This ensures that the printed products are pushed all the way into the pockets and that the trailing edges are already aligned on the support member. In particular, the trailing edges are prevented from fluttering.

Die Mitnehmer weisen vorzugsweise einen schwenkbar gefederten Ausleger auf, wobei dieser Ausleger vorzugsweise durch ein erstes Ende einer quer zum Förderelement angeordneten Schraubenfeder gebildet ist, deren zweites Ende bezüglich dem Förderelement justiert ist. Ein solcher Mitnehmer ist sehr einfach aufgebaut, da der Ausleger und das Federelement eine Einheit bilden.The carriers preferably have a pivotably sprung boom, this boom preferably being formed by a first end of a helical spring arranged transversely to the conveying element, the second end of which is adjusted with respect to the conveying element. Such a driver has a very simple structure, since the boom and the spring element form a unit.

In einer weiteren bevorzugten Ausbildungsform ist die Fixierung des zweiten Endes einstellbar. Dadurch kann die Zeitdauer des Festhaltens der Druckereierzeugnisse bei der Kreuzungsstelle eingestellt werden.In a further preferred embodiment, the fixation of the second end is adjustable. This can increase the amount of time that the printed matter is held be set at the crossing point.

Weitere bevorzugte Ausführungsformen sind den weiteren abhängigen Ansprüchen angegeben.Further preferred embodiments are specified in the further dependent claims.

Dem Schaufelrad 10 ist ein nicht dargestellter Falzapparat vorgeschaltet, von dem die austretenden, gefalzten Druckereierzeugnisse 16, beispielsweise Zeitungen, Zeitschriften oder Teile davon in die Taschen 12 des Schaufelrades 10 fallen. Wie aus Fig. 1 hervorgeht, treten die Druckereierzeugnisse 16 mit ihrer Falzkante 16a voraus aus dem Falzapparat aus. Diese Falzkante 16a wird in Drehrichtung B des Schaufelrades 10 gesehen somit zur vorlaufenden Kante.In Fig. 1, the paddle wheel 10 of a printing machine is shown purely schematically, which has a plurality of pockets 12 open on its circumference. The bottom of the pockets 12 is designated 12a. The paddle wheel 10 is rotatable on a fixed shaft 14 stored and is driven in the direction of arrow B with the rotational speed v ₁ rotating. The paddle wheel 10 is preceded by a folder, not shown, from which the emerging, folded printed products 16, for example newspapers, magazines or parts thereof, fall into the pockets 12 of the paddle wheel 10. As is apparent from Fig. 1, the printed products 16 emerge from the folder with their folded edge 16a. This fold edge 16a is thus seen in the direction of rotation B of the paddle wheel 10 to the leading edge.

Unterhalb dem Schaufelrad 10 ist ein Wegförderer 18 angeordnet, welchem ein Bandförderer 20 für den Wegtransport der auf dem Wegförderer 18 gebildeten Schuppenformation S nachgeschaltet ist. Dem Wegförderer 18 ist eine Mitnehmeranordnung 22 vorgeschaltet, wobei die Bewegungsbahn von Mitnehmern 24 auf der förderwirksamen Strecke, die durch den Wegförderer 18 definierte Transportebene an einer Kreuzungsstelle 26 überschneidet. Die Förderrichtung des Wegförderers 18 sowie des Bandförderers 20 ist mit C bezeichnet, diejenige der Mitnehmeranordnung 22 mit G. Die Fördergeschwindigkeit des Wegförderers 18 und des Bandförderers 20 beträgt v₂.Arranged below the paddle wheel 10 is a conveyor 18, which is followed by a belt conveyor 20 for transporting away the scale formation S formed on the conveyor 18. A driver arrangement 22 is connected upstream of the conveyor 18, the movement path of drivers 24 on the conveyor-effective route overlapping the transport plane defined by the conveyor 18 at an intersection 26. The conveying direction of the conveyor 18 and the belt conveyor 20 is designated C, that of the driver assembly 22 with G. The conveying speed of the conveyor 18 and the belt conveyor 20 is v₂.

An den Endbereichen von parallelen Seitenplatten 28, 28′ (s. Figuren 1 und 2) sind paarweise Lagerungselemente 30 angeordnet. An ihnen sind zwei parallele Wellen 32, 34 drehbar gelagert. An der in Richtung des Pfeiles D angetriebenen Welle 32 ist ein Paar voneinander beabstandeter Bandrollen 36 drehfest angeordnet. Die Welle 32 ist mit einem strichpunktiert dargestellten Kettentrieb 38 mit der Welle 34, in der Phasenlage einstellbar, wirkverbunden. An der Welle 34 ist ein Kettenrad 40 drehfest angeordnet, während an ihr ein weiteres Paar Bandrollen 42 und Umlenkkettenräder 44 drehbar gelagert sind. Im Bereich der Welle 34 sind zwei, diese koaxial umgreifende und gegen die Welle 32 keilförmig auslaufende Kulissen 46 und an der Welle 32 zwei entsprechende Kulissenrollen angeordnet. An der Welle 32 sind ebenfalls analoge Umlenkkettenräder 44 und Bandrollen 36 vorgesehen. Um die Bandrollen 36, 42 laufen zwei parallele, endlose Bänder 50. Um die an den Wellen 32 und 34 angeordneten Umlenkkettenräder 44 sind zwei parallele endlose Ketten 52 geführt. Die Umlenkkettenräder 44 sind derart angetrieben, dass die Umlaufgeschwindigkeit der Ketten 52 gleich jener der Bänder 50 ist. An den Ketten 52 sind in festen Abständen strichpunktiert dargestellte Greifer 54 angeordnet. Die Greifer 54 weisen seitlich an den Ketten 52 befestigte Greiferkörper 56 auf, an denen federnde Finger 58 angeordnet sind. Im Bereich der Wellen 32 und 34 werden die Finger 58 mittels den Kulissen 46 bzw. Kulissenrollen in die gestrichelt dargestellte Oeffnungsstellung überführt. Beim Ablaufen der Finger ab den Kulissen 46 bzw. den Kulissenrollen gehen diese in die Klemmstellung über und klemmen auf der förderwirksamen Strecke die nachlaufenden Kanten der Druckereierzeugnisse 16 ein oder liegen auf der nicht förderwirksamen Strecke am Greiferkörper 56 an. In den Figuren 1 und 2 ist jeweils nur ein Paar Greifer 54 dargestellt.At the end regions of parallel side plates 28, 28 '(see FIGS. 1 and 2), bearing elements 30 are arranged in pairs. Two parallel shafts 32, 34 are rotatably mounted on them. On the shaft 32, which is driven in the direction of the arrow D, a pair of spaced-apart band rollers 36 are arranged in a rotationally fixed manner. The shaft 32 is provided with a chain drive 38 shown in broken lines with the shaft 34, adjustable in phase, operatively connected. A sprocket 40 is arranged in a rotationally fixed manner on the shaft 34, while a further pair of belt rollers 42 and deflection sprockets 44 are rotatably mounted on it. In the area of the shaft 34, two baffles 46, which coaxially encompass these and wedge-shaped against the shaft 32, and two corresponding bobbin rollers are arranged on the shaft 32. Analogue deflection sprockets 44 and belt rollers 36 are also provided on the shaft 32. Two parallel, endless belts 50 run around the belt rollers 36, 42. Two parallel, endless chains 52 are guided around the deflection sprockets 44 arranged on the shafts 32 and 34. The deflection sprockets 44 are driven such that the rotational speed of the chains 52 is the same as that of the belts 50. On the chains 52, grippers 54 shown in dash-dot lines are arranged at fixed intervals. The grippers 54 have gripper bodies 56 fastened to the sides of the chains 52, on which resilient fingers 58 are arranged. In the area of the shafts 32 and 34, the fingers 58 are moved into the open position shown in dashed lines by means of the scenes 46 or scenery rollers. When the fingers run off the scenes 46 or the scenery rollers, they pass into the clamping position and clamp the trailing edges of the printed products 16 on the conveyor-effective route or rest on the gripper body 56 on the route which is not conveyor-effective. Only one pair of grippers 54 is shown in FIGS. 1 and 2.

Die Welle 32 ist mittels einem weiteren Kettentrieb 60 mit dem Abtrieb eines ebenfalls an den Seitenplatten 28, 28′ drehbar gelagerten Differentialgetriebes 62 wirkverbunden. Eine strichpunktiert dargestellte Kette 64 eines weiteren Kettentriebes 66 umschlingt mit Hilfe der Umlenkräder 68, 68′ das Antriebsrad des Differentialgetriebes 62, was eine Drehrichtungsumkehr gegenüber dem antreibenden Kettenrad 70 zur Folge hat (vgl. Pfeile E und F). Das Kettenrad 70 wird mit einem strichpunktiert dargestellten Kettentrieb 72 von der Welle 14 des Schaufelrades 10 angetrieben. Mit dem Differentialgetriebe 62 kann eine Phasenverschiebung zwischen dem Schaufelrad 10 und dem Wegförderer 18 sowie der Mitnehmeranordnung 22 eingestellt werden, indem beispielsweise kurzzeitig die Relativdrehzahl zwischen dem Antriebs- und Abtriebsrad des Differentialgetriebes 62 vergrössert oder verkleinert wird.The shaft 32 is operatively connected by means of a further chain drive 60 with the output of a differential gear 62 which is also rotatably mounted on the side plates 28, 28 '. A chain-dotted chain 64 of another chain drive 66 wraps around with the aid of the deflection wheels 68, 68 ', the drive wheel of the differential gear 62, which results in a reversal of the direction of rotation relative to the driving sprocket 70 (see arrows E and F). The sprocket 70 is driven by a chain drive 72 shown in phantom by the shaft 14 of the paddle wheel 10. The differential gear 62 can be used to set a phase shift between the paddle wheel 10 and the removal conveyor 18 and the driver arrangement 22, for example by briefly increasing or reducing the relative speed between the drive and driven wheels of the differential gear 62.

An den Seitenplatten 28, 28′ sind im Bereich der Welle 34 Halteplatten 74, 74′ befestigt (s. Fig. 1 und 2). An den Halteplatten 74 ist in Langlöchern 75 mittels Schraubenbolzen 76 eine Welle 78 befestigt, an welcher ein Kettenrad 80 drehbar gelagert ist. Um die beiden Kettenräder 40 und 80 ist eine endlos umlaufende Förderkette 82 geführt. An dieser sind in festen Abständen die weiter oben erwähnten Mitnehmer 24 angeordnet. Sie sind weiter unten näher beschrieben. Parallel zum förderwirksamen Trum der Förderkette 82 ist zwischen dieser und dem Schaufelrad 10 ein Führungsblech 84 angeordnet, welches über das obere Ende der Mitnehmeranordnung 22 vorsteht und dort parallel zum Rand des Schaufelrades 10 gebogen ist. Das untere Ende des Führungsblechs 84 reicht bis zur Kreuzungsstelle 26. In der Fig. 2 ist das Führungsblech 84 nicht dargestellt, um die Sicht in Pfeilrichtung A in das Schaufelrad 10 nicht zu verdecken, von diesem ist nur die untere Hälfte sichtbar. Mit 16′ ist in der Fig. 1 die nachlaufende Kante eines Druckereierzeugnisses 16 bezeichnet, welche am Führungsblech 84 in dessen oberem Endbereich streift, weil das betreffende Druckereierzeugnis 16 nicht am Boden der Tasche 12a ansteht.On the side plates 28, 28 '34 holding plates 74, 74' are fixed in the region of the shaft (see. Fig. 1 and 2). A shaft 78, on which a sprocket 80 is rotatably mounted, is fastened to the holding plates 74 in elongated holes 75 by means of screw bolts 76. An endlessly rotating conveyor chain 82 is guided around the two chain wheels 40 and 80. The carriers 24 mentioned above are arranged at this at fixed intervals. They are described in more detail below. A guide plate 84 is arranged between the conveyor chain 82 and the conveyor chain 82, which protrudes beyond the upper end of the driver arrangement 22 and is bent there parallel to the edge of the blade wheel 10. The lower end of the guide plate 84 extends to the crossing point 26. In FIG. 2, the guide plate 84 is not shown in order not to obscure the view in the direction of arrow A into the impeller 10, only the lower half of this is visible. With 16 'in Fig. 1, the trailing edge of a printed product 16 is referred to, which grazes on the guide plate 84 in its upper end region, because the relevant printed product 16 is not present at the bottom of the pocket 12a.

Die Taschen 12 des Schaufelrades 10 werden von mehreren parallel zueinander angeordneten, gebogenen Taschenblechen 86 gebildet (s. insbesondere Fig. 2). Zwischen den in Axialrichtung der Welle 14 voneinander beabstandeten Taschenblechen 86 sind jeweils Ausstossorgane 88 angeordnet, wovon in der Fig. 1 eines dargestellt ist. Beim Ausstossen des Druckereierzeugnisses 16 aus dem Schaufelrad 10 kommen die vorlaufenden Kanten 16a an den Ausstossorganen 88 zur Auflage.The pockets 12 of the paddle wheel 10 are formed by a plurality of curved pocket plates 86 arranged parallel to one another (see in particular FIG. 2). Ejection elements 88 are arranged between the pocket plates 86 spaced apart from one another in the axial direction of the shaft 14, one of which is shown in FIG. 1. When the printed product 16 is ejected from the impeller 10, the leading edges 16a come to rest on the ejection elements 88.

An der Kreuzungsstelle 26 ist parallel zum förderwirksamen Trum der Bänder 50 ein Auflageorgan 90, beispielsweise aus Kunststoff, angeordnet. Wie weiter unten beschrieben ist, kommen auf diesem Auflageorgan 90 die nachlaufenden Kanten der Druckereierzeugnisse 16 zur Auflage und von ihm werden schwenkbar und gefedert gelagerte Ausleger 92 der Mitnehmer 24 aus dem Einwirkbereich auf die Druckereierzeugnisse 16 verschwenkt. Die Ausleger 92 stehen auf ihrer förderwirksamen Strecke über das Führungsblech 84 vor und greifen mit ihren freien Enden in die Taschen 12 des Schaufelrades 10.At the intersection 26, a support member 90, for example made of plastic, is arranged parallel to the conveyor 50's conveyor belt. As will be described further below, the trailing edges of the printed products 16 come to rest on this support member 90, and cantilevers 92 of the catches 24 which are mounted so as to be pivotable and spring-loaded are pivoted out of the active area on the printed products 16. The cantilevers 92 protrude over the guide plate 84 on their conveying path and engage with their free ends in the pockets 12 of the paddle wheel 10.

In den Figuren 3 und 4 sind einige Glieder der Förderkette 82 mit einem Paar an diesem befestigte Mitnehmer 24 vergrössert dargestellt. Auf die freien Enden von zwei verlängerten Bolzen 94 der Förderkette 82 sind zwei Mitnehmerplatten 96 aufgesteckt, die mittels Abstandshülsen 98 von den Laschen 100 der Förderkette 82 beabstandet sind. An einem Ende sind die Bolzen 94 mit einem Kopf 102 ausgestattet, und das andere Ende wird mittels einer Klammer 104 gegen axiale Verschiebung festgehalten. Um die, in Förderrichtung G gesehen, an dem vorlaufenden Bolzen 94 angeordneten Abstandshülsen 98 ist je eine gegensinnig gewickelte Schraubenfeder 106 angeordnet. Das erste freie Federende 108 ist in seinem Endbereich schlaufenförmig gebogen und übernimmt die weiter oben beschriebene Funktion des Auslegers 92 (vgl. auch Fig. 1). Das zweite Federende 110 durchstösst ein radiales Loch in einem Fixierbolzen 112. Der Fixierbolzen 112 ist in einem parallel zu dem betreffenden Laschen 100 verlaufenden Langloch 114 in jeder Mitnehmerplatte 96 verschiebbar befestigt. In der mit ausgezogenen Linien dargestellten Lage steht das erste Federende 108 bezüglich der Richtung des Pfeiles G ungefähr rechtwinklig von der Förderkette 82 ab. Durch Verschieben des Fixierbolzens 112 im Langloch 114 in Richtung des Pfeiles G kann das erste Federende 108 die strichpunktiert angegebene und mit 108′ bezeichnete Ruhelage erhalten. Es kann aber durch Verschieben des Fixierbolzens 112 entgegen dem Pfeil G auch in eine gegenüber den Mitnehmerplatten 96 vorlaufende Ruhelage gebracht werden. Die nachlaufende Kante des Druckereierzeugnisses 16 ist auf dem Auflageorgan 90 abgelegt und zwischen diesem und dem ersten Federende 108 eingeklemmt.In FIGS. 3 and 4, some links of the conveyor chain 82 are shown enlarged with a pair of drivers 24 attached to it. On the free ends of two elongated bolts 94 of the conveyor chain 82, two driver plates 96 are plugged on, which are spaced from the plates 100 of the conveyor chain 82 by means of spacer sleeves 98. At one end the bolts 94 are provided with a head 102 and the other end is held against axial displacement by means of a clamp 104. A helical spring 106 wound in opposite directions is arranged around the spacer sleeves 98 arranged on the leading bolt 94, as seen in the conveying direction G. The first free spring end 108 is loop-shaped in its end region and takes over the function of the boom 92 described above (cf. also FIG. 1). The second spring end 110 pierces a radial hole in a fixing bolt 112. The fixing bolt 112 is slidably fastened in an elongated hole 114 running parallel to the respective lugs 100 in each driver plate 96. In the position shown with solid lines, the first spring end 108 projects approximately at right angles from the conveyor chain 82 with respect to the direction of the arrow G. By moving the fixing bolt 112 in the elongated hole 114 in the direction of arrow G, the first spring end 108 can receive the rest position indicated by dash-dotted lines and designated by 108 '. However, by moving the fixing bolt 112 against the arrow G, it can also be brought into a rest position leading in relation to the driver plates 96. The trailing edge of the printed product 16 is placed on the support member 90 and clamped between the latter and the first spring end 108.

In den Figuren 5 und 6 ist die Kreuzungsstelle 26 vergrössert dargestellt, wobei an den Ketten 52 in festen Abständen Nocken 116 angeordnet sind, welche an den nachlaufenden Kanten der Druckereierzeugnisse 16 zur Anlage kommen und diese auf einem Förderblech 118 in Förderrichtung C wegschieben. Die Nocken 116 sind am Bolzen 120 der Kette 52 schwenkbar gelagert, und ein zu diesem Bolzen 120 konzentrisches Langloch 122 im Nocken 116 ist in einem benachbarten, weiteren Bolzen 124 der Kette 52 schwenkbar geführt. Beim Auflaufen des Nockens 116 auf ein Kulissenorgan 126 wird dieser im Gegenuhrzeigersinn verschwenkt, so dass ein am Nocken 116 angeformter Haken 128 über das Förderblech 118 vorsteht. In Fig. 6 ist die Kette 52 nur noch strichpunktiert angedeutet. An der Kreuzungsstelle 26 überschneiden sich die Bewegungsbahn der Mitnehmer 24 und die in den Figuren 5 und 6 durch das Förderblech 118 festgelegte Transportebene des Wegförderers 18. Die Förderkette 82 verläuft parallel zum Führungsblech 84, und das erste Federende 108 des Mitnehmers 24 steht über das Führungsblech 84 vor.In Figures 5 and 6, the intersection 26 is shown enlarged, with the chains 52 in fixed Distances cam 116 are arranged, which come to rest on the trailing edges of the printed products 16 and push them away on a conveyor plate 118 in the conveying direction C. The cams 116 are pivotally mounted on the pin 120 of the chain 52, and an elongated hole 122 in the cam 116, which is concentric with this pin 120, is pivotably guided in an adjacent, further pin 124 of the chain 52. When the cam 116 runs onto a link element 126, it is pivoted counterclockwise, so that a hook 128 formed on the cam 116 protrudes beyond the conveyor plate 118. 6, the chain 52 is only indicated by dash-dotted lines. At the intersection 26, the movement path of the drivers 24 and the transport plane of the conveyor 18 defined by the conveyor plate 118 in FIGS. 5 and 6 overlap. The conveyor chain 82 runs parallel to the guide plate 84, and the first spring end 108 of the driver 24 projects above the guide plate 84 before.

Anhand der Figuren 3, 5 und 6 wird die Funktionsweise des Mitnehmers 24 sowie der Nocken 116 näher beschrieben.The mode of operation of the driver 24 and of the cams 116 is described in more detail with reference to FIGS. 3, 5 and 6.

Das erste Federende 108 des in Förderrichtung G bewegten Mitnehmers 24 kommt zusammen mit dem Druckereierzeugnis 16 auf dem Auflageorgan 90 zur Anlage. Die nachlaufende Kante des Druckereierzeugnisses 16 wird zwischen dem Auflageorgan 90 und dem ersten Federende 108 festgeklemmt (Fig. 3 und 5). Beim Weiterbewegen des Mitnehmers 24 in Pfeilrichtung G wird das erste Federende 108 infolge des Auflageorganes 90 im Uhrzeigersinn verdreht, bis es die nachlaufende Kante des Druckereierzeugnisses 16 freigibt (s. Fig. 6). Kurz bevor das Druckereierzeugnis 16 freigegeben wird, kommt ein Haken 128 eines Nockens 116 an die nachlaufende Kante zur Anlage und fördert das Druckereierzeugnis 16 in Pfeilrichtung C weg. Sobald das freie Ende des Federendes 108 das Auflageorgan 90 passiert hat, schwenkt es in seine ursprüngliche Lage im Gegenuhrzeigersinn zurück. Die Fördergeschwindigkeiten der Kette 52 und der Förderkette 82 sowie die Abstände der Mitnehmer 24 bzw. Nocken 116 sind so aufeinander abgestimmt, dass auf jedes vom Schaufelrad 10 freigegebene Druckereierzeugnis 16 ein Mitnehmer 24 zur Auflage kommt, und kurz bevor die Druckereierzeugnisse 16 vom Mitnehmer 24 freigegeben werden, diese an ihren nachlaufenden Kanten vom Haken 128 ergriffen werden.The first spring end 108 of the driver 24 moved in the conveying direction G comes to rest together with the printed product 16 on the support member 90. The trailing edge of the printed product 16 is clamped between the support member 90 and the first spring end 108 (FIGS. 3 and 5). When the driver 24 moves further in the direction of the arrow G, the first spring end 108 is rotated clockwise as a result of the support member 90 until it is the trailing edge of the printed product 16 releases (see Fig. 6). Shortly before the printed product 16 is released, a hook 128 of a cam 116 comes to rest against the trailing edge and conveys the printed product 16 away in the direction of arrow C. As soon as the free end of the spring end 108 has passed the support member 90, it swings back into its original position in a counterclockwise direction. The conveyor speeds of the chain 52 and the conveyor chain 82 and the spacing of the drivers 24 or cams 116 are coordinated with one another such that a driver 24 comes into contact with each printed product 16 released by the paddle wheel 10, and shortly before the printed products 16 are released by the driver 24 be caught by their hooks 128 at their trailing edges.

Anhand der Fig. 1 wird nun die Funktionsweise der Vorrichtung zum Uebernehmen von Druckereierzeugnissen 16 von einem umlaufend angetriebenen Schaufelrad 10 einer Druckereimaschine dargelegt. Die Druckereierzeugnisse 16 werden in bekannter Art und Weise von oben in die Taschen 12 des Schaufelrades 10 eingeschossen. Falls ein Druckereierzeugnis 16 dabei verkantet oder nicht bis zum Boden der Taschen 12a vorgeschoben wird, wie dies mit 16′ angedeutet ist, so kommen die um das Kettenrad 80 umlaufenden Federenden 108 der Mitnehmer 24 auf die nachlaufende Kante des Druckereierzeugnisses 16′ zur Auflage und schieben dieses in die entsprechende Tasche 12, bis die vorlaufende Kante 16a am Boden der Taschen 12a anstehet. Die Fördergeschwindigkeit der Mitnehmeranordnung 22 ist derart vorgewählt, dass sie gleich oder grösser ist als die Geschwindigkeit der nachlaufenden Kanten der Druckereierzeugnisse 16 vor der Kreuzungsstelle 26. Die Geschwindigkeit der freien Enden der Federenden 108 ist aber infolge der Krümmung im Bereich des Kettenrades 80 erhöht, so dass die am Führungsblech 84 gleitende, nachlaufende Kante 16′ erfasst und somit das Druckereierzeugnis 16 ganz in die Tasche 12 gefördert wird. Dies garantiert, dass alle vorlaufenden Kanten 16a am Boden der Taschen 12a anstehen und somit ausgerichtet sind. Beim Weiterdrehen des Schaufelrades 10 in Pfeilrichtung B kommen die vorlaufenden Kanten 16a auf dem Ausstossorgan 88 zur Anlage, was zur Folge hat, dass die Druckereierzeugnisse 16 aus den Taschen 12 gleiten. Dabei gelangt die nachlaufende Kante jedes Druckereierzeugnisses 16 auf dem Auflageorgan 90 zur Auflage und wird dort, wie weiter oben beschrieben, von dem der nachlaufenden Kante des Druckereierzeugnisses 16 zugeordneten Mitnehmer 24 so lange festgeklemmt, bis der Mitnehmer 24 die Kreuzungsstelle 26 passiert hat und das Auflageorgan 90 das Federende 108 aus dem Einwirkbereich auf das Druckereierzeugnis 16 zurückgeschwenkt hat. Die Reibung zwischen dem letzten auf die Schuppenformation S aufgelegten Druckereierzeugnisses 16 und dem vom Mitnehmer 24 freigegebenen Druckereierzeugnis 16 ist nun so gross, dass keine Relativverschiebung zwischen diesen beiden Druckereierzeugnissen 16 auftreten kann.1, the mode of operation of the device for taking over printed products 16 from a rotatingly driven paddle wheel 10 of a printing machine will now be explained. The printed products 16 are shot in a known manner from above into the pockets 12 of the paddle wheel 10. If a printed product 16 is tilted or is not pushed to the bottom of the pockets 12a, as indicated by 16 ', the spring ends 108 of the catch 24 rotating around the sprocket 80 come to rest on the trailing edge of the printed product 16' and push this into the corresponding pocket 12 until the leading edge 16a abuts the bottom of the pockets 12a. The conveying speed of the driver arrangement 22 is preselected such that it is equal to or greater than the speed of the trailing one Edges of the printed products 16 in front of the crossing point 26. The speed of the free ends of the spring ends 108 is increased due to the curvature in the region of the sprocket 80, so that the trailing edge 16 'sliding on the guide plate 84' detects and thus the printed product 16 entirely in the Pocket 12 is promoted. This guarantees that all leading edges 16a abut the bottom of the pockets 12a and are thus aligned. As the impeller 10 continues to rotate in the direction of the arrow B, the leading edges 16a come to rest on the ejection element 88, with the result that the printed products 16 slide out of the pockets 12. The trailing edge of each printed product 16 comes to rest on the support member 90 and, as described above, is clamped there by the driver 24 assigned to the trailing edge of the printed product 16 until the driver 24 has passed the crossing point 26 and the support member 90 has pivoted the spring end 108 back out of the area affected by the printed product 16. The friction between the last printed product 16 placed on the scale formation S and the printed product 16 released by the carrier 24 is now so great that no relative displacement between these two printed products 16 can occur.

Der Abstand der Druckereierzeugnisse 16 in der Schuppenformation S wird durch die Frequenz der ausgelegten Druckereierzeugnisse 16 sowie die Fördergeschwindigkeit v₂ des Wegförderers 18 und des Bandförderers 20 bestimmt.The distance between the printed products 16 in the scale formation S is determined by the frequency of the printed products 16 laid out and the conveying speed v 2 of the conveyor 18 and the belt conveyor 20.

Bei der vorgeschlagenen Vorrichtung legen die Druckereierzeugnisse 16 somit keine Strecke im freien Fall zurück, was ein Verschieben infolge des Luftzuges durch das Schaufelrad 10 verunmöglicht. Wie bereits weiter oben erwähnt, sind alle Druckereierzeugnisse 16 ausgerichtet und ihr Abstand in der Schuppenformation S ist konstant, weil sie in der Kreuzungsstelle 26 kurzzeitig festgehalten werden. Mittels den in der Fig. 1 strichpunktiert dargestellten Greifern 54 können die Druckereierzeugnisse 16 auf der förderwirksamen Strecke des Wegförderers 18 festgehalten werden, so dass kein Verschieben mehr möglich ist, dies auch bei Wegförderern 18 mit Nocken 116 der Fall. Auf die Greifer 54 kann aber durchaus auch verzichtet werden. In diesem Fall entfällt natürlich die Kette 52 mitsamt den Umlenkkettenrädern 44, was die Vorrichtung erheblich vereinfacht.In the proposed device, the printed products 16 thus do not cover a distance in free fall, which makes it impossible to move due to the draft through the paddle wheel 10. As already mentioned above, all printed products 16 are aligned and their distance in the scale formation S is constant because they are briefly held in the intersection 26. By means of the grippers 54 shown in dash-dotted lines in FIG. 1, the printed products 16 can be held on the route of the conveyor 18 which is effective for conveying, so that displacement is no longer possible, even in the case of conveyors 18 with cams 116. However, the grippers 54 can also be dispensed with. In this case the chain 52 together with the deflection sprockets 44 is of course omitted, which considerably simplifies the device.

Es ist durchaus einleuchtend, dass durch die vorwählbare Ruhelage des ersten Federendes 108, 108′ (s. Fig. 3) der Mitnehmer 24 die Zeitdauer, während der die Druckereierzeugnisse 16 an der Kreuzungsstelle 26 festgehalten werden, einstellbar ist. So ist diese länger, bei einer Ruhelage, die mit 108 bezeichnet ist, als bei einer mit 108′ angedeuteten.It is quite clear that the preselectable rest position of the first spring end 108, 108 '(see FIG. 3) of the driver 24 allows the time period during which the printed products 16 are held at the intersection 26 to be adjustable. So this is longer, with a rest position, which is designated with 108, than with a 108 'indicated.
