Abstract

The substantially quadrangular sheet-like structures (15) are fed from above to a pile compartment (18), bounded by stop rails (19, 20, 21, 22), by means of one section (12) of a conveyor. In order that the sheet-like structures (15) strike against two stop rails (19, 20), at right angles to each other, at the moment they reach the pile compartment (18), the sheet-like structures (15) are fed on the section (12) of the conveyor with one of their corners ahead in a conveying direction (17) which forms an angle other than 0 DEG and 90 DEG , preferably about 45 DEG , with the side edges of the sheet-like structures (15) adjoining the said corner. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Einrichtung 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 beispielsweise aus der GB-PS 1 568 752 bekannt. Bei dieser bekannten Einrichtung ist der unmittelbar in den Stapelschacht einmündende Abschnitt des Förderers unterhalb des vorangehenden Abschnittes angeordnet und hat bezüglich desselben eine praktisch entgegengesetzte Förderrichtung. Bei der bekannten Einrichtung gelangen daher die Druckereiprodukte mit jener Kante voraus in den Stapelschacht, die auf dem vorangehenden Abschnitt des Förderers die nachlaufende Kante war. Dies ist vor allem dann vorteilhaft, wenn die anfallenden Drukkereiprodukte in einem herkömmlichen Schuppenstrom anfallen, in welchem die vorlaufende Kante der Druckereiprodukte in der Regel durch den Falz gebildet ist, während die gegenüberliegende Kante eine sogenannte Schnittkante ist. Bei der bekannten Vorrichtung wird somit unter anderen Dingen verhütet, dass beim Eintreffen in den Stapelschacht die heiklere Kante der Druckereiprodukte, nämlich der Falz, auf die den Stapelschacht begrenzenden Anschlagschienen aufschlägt.Such a device is known for example from GB-PS 1 568 752. In this known device, the section of the conveyor opening directly into the stacking shaft is arranged below the preceding section and has a practically opposite conveying direction with respect to the same. In the known device, therefore, the printed products reach the stacking chute with the edge that was the trailing edge on the preceding section of the conveyor. This is particularly advantageous when the resulting printing products are produced in a conventional stream of shingles, in which the leading edge of the printing products is generally formed by the fold, while the opposite edge is a so-called cut edge. In the known device, it is thus prevented, among other things, that the more delicate edge of the printed products, namely the fold, strikes the stop rails delimiting the stacking shaft when it arrives in the stacking shaft.

Bei der bekannten Einrichtung ist aber die Förderrichtung beider Abschnitte des Förderers stets im wesentlichen rechtwinklig zu der vor- und der nachlaufenden Kante der Druckereiprodukte. Dies hat zur Folge, dass beim Eintreffen in den Stapelschacht nur jeweils die vorlaufende Kante an die gegenüberliegende Anschlagschiene anschlägt und dabei in dem sich bildenen Stapel ausgerichtet wird, während die Seitenkanten beim Eintreffen in den Stapelschacht ungeführt bleiben und damit nicht selbsttätig ausgerichtet werden. Es wären also bei der bekannten Einrichtung entweder im Stapelschacht selbst und/oder auf dem in diesen einmündenden Abschnitt des Förderers Seitenrichter erforderlich, die die Seitenkanten der anfallenden Druckereiprodukte in bezug aufeinander ausrichten, damit ein sauberer, quaderförmiger Stapel entsteht.In the known device, however, the direction of conveyance of both sections of the conveyor is always essentially perpendicular to the leading and trailing edge of the printed products. This has the consequence that when it arrives in the stacking shaft only the leading edge strikes the opposite stop rail and is thereby aligned in the stack being formed, while the side edges remain unguided when they arrive in the stacking shaft and are therefore not automatically aligned. It would therefore be necessary in the known device either in the stacking shaft itself and / or on the section of the conveyor opening into this side judge who align the side edges of the resulting printed products with respect to one another, so that a clean, rectangular stack is formed.

Bei diesem Stand der Technik ist es als eine Aufgabe der Erfindung anzusehen, eine Einrichtung der eingangs genannten Art derart zu gestalten, dass ein sauberer, quaderförmiger Stapel entsteht, ohne dass zusätzliche technische Massnahmen erforderlich wären.In this prior art, it is an object of the invention to design a device of the type mentioned at the outset in such a way that a clean, cuboid stack is produced without additional technical measures being necessary.

Diese Aufgabe wird durch die vorgeschlagene Einrichtung dadurch gelöst, dass sie die im Rennzeichen des Patentanspruches 1 umschriebenen Merkmale aufweist.This object is achieved by the proposed device in that it has the features described in the racing character of claim 1.

Merkmale bevorzugter Ausführungsformen sind in den abhängigen Ansprüchen umschrieben.Features of preferred embodiments are described in the dependent claims.

Aus der US-A-3,239,676 ist eine Vorrichtung zum Zählen von in einem Schuppenstrom anfallenden Druckereiprodukten bekannt, die mittels eines ersten Förderers in einer Formation zugeführt werden, in der die vorlaufenden kanten der Druckereierzeugnisse rechtwinklig zur Zuführrichtung verlaufen und die zu dieser Zuführrichtung parallelen Seitenkanten der Druckereiprodukte aufeinander ausgerichtet sind. An diesen ersten Förderer schliesst ein unterhalb diesem angeordneter zweiter Förderer an, dessen Förderrichtung mit derjenigen des ersten Förderers einen spitzen Winkel bildet. Der zweite Förderer fördert die Druckereiprodukte nun mit einer Ecke voraus entlang einer Zählstrecke, in der unter Ausnützung der nun seitlich freiliegenden Ecken der Druckereiprodukte eine einfache und zuverlässige Produktezählung erfolgen kann. Dem zweiten Förderer ist ein dritter Förderer nachgeschaltet, dessen Förderrichtung zu derjenigen des ersten Förderers parallel ist und der die Druckereiprodukte nach der Zählung in derselben Schuppenformation wegführt, in der die Druckereiprodukte durch den ersten Förderer zugeführt wurden, d.h. also mit sich rechtwinklig zur Förderrichtung erstreckender vorlaufender Kante. Die in Schuppenformation anfallenden Druckereiprodukte werden demnach nur für die Zählung über eine gewisse Strecke schräggefördert und anschliessend wieder in der ursprünglichen Formation weitergefördert.From US-A-3,239,676 an apparatus for counting printed products accumulating in a shingled stream is known, which are fed by means of a first conveyor in a formation in which the leading edges of the printed products run at right angles to the feed direction and the side edges of the parallel to this feed direction Printed products are aligned. This second conveyor is adjoined by a second conveyor arranged below it whose conveying direction forms an acute angle with that of the first conveyor. The second conveyor now conveys the printed products with a corner ahead along a counting section in which a simple and reliable product count can be made using the corners of the printed products that are now exposed to the side. The second conveyor is followed by a third conveyor, the conveying direction of which is parallel to that of the first conveyor and which, after counting, leads the printed products away in the same scale formation in which the printed products were fed by the first conveyor, that is to say with the leading conveyor extending at right angles to the conveying direction Edge. The printed products in scale form are therefore only inclined for counting over a certain distance and then conveyed on again in the original formation.

The invention is described below purely for example with reference to the drawing. It shows:
  • Figure 1 is a schematic plan view of the transition between the two sections of the conveyor leading to the stacking shaft.
  • 2 shows a schematic plan view of the end of the section of the conveyor opening into the stacking shaft;

In Fig. 1 ist eine Draufsicht auf einen Teil eines einen Stapelschacht beschickenden Förderers 10 dargestellt. Dieser Förderer 10 besteht aus zwei Abschnitten 11,12, wobei vom Abschnitt 11 lediglich das Ende und vom Abschnitt 12 lediglich der Anfang gezeigt ist. Der Abschnitt 11 besteht aus einem Riemchenförderer 13, auf dem Druckereiprodukte - hier Zeitungen 15 - in einem frei aufliegenden Schuppenstrom in Richtung des Pfeiles 14 gefördert werden. Die Förderrichtung 14 ist hier rechtwinklig zu den vor- und den nachlaufenden Kanten der Zeitungen 15. Der an das Ende des Abschnittes 11 anschliessende Abschnitt 12 weist ebenfalls einen Riemchenförderer 16 auf, dessen Förderrichtung 17 gegenüber der Förderrichtung 14 des Abschnittes 11 um einen Winkel - hier beispielsweise etwa 45° - abgelenkt ist. Die auf den Abschnitt 12 übergebenen Zeitungen 15 werden daher, wie gezeigt, wiederum in einem Schuppenstrom gefördert, doch ist ihre Lage inbezug auf die nun herrschende Förderrichtung 17 um 45° verdreht, so dass auf dem Abschnitt 12 jeweils eine Ecke das vorlaufende Ende einer Zeitung 15 bildet.1 shows a top view of part of a conveyor 10 loading a stacking shaft. This conveyor 10 consists of two sections 11, 12, only the end of section 11 and only the beginning of section 12 being shown. Section 11 consists of an apron conveyor 13, on which printed products - here newspapers 15 - are conveyed in a freely lying scale stream in the direction of arrow 14. The conveying direction 14 is here at right angles to the leading and trailing edges of the newspapers 15. The section 12 adjoining the end of the section 11 likewise has an apron conveyor 16, the conveying direction 17 of which is at an angle with respect to the conveying direction 14 of the section 11 - here for example about 45 ° - is deflected. The newspapers 15 transferred to section 12 are therefore, as shown, in turn conveyed in a stream of shingles, but their position is rotated by 45 ° with respect to the conveying direction 17 now prevailing, so that the section 12 each form a corner the leading end of a newspaper 15.

Zweckmässig hat die Fördergeschwindigkeit in der Förderrichtung 17 eine Komponente, die bezüglich Richtung und Grösse der Geschwindigkeit in Förderrichtung 14 entspricht. Dadurch ist der Übergang der Zeitungen vom Abschnitt 11 zum Abschnitt 12 besonders "sanft" und es tritt nur ein Mindestmass an Beschleunigung auf, die auf die Zeitung wirksame Kräfte zur Folge hat.The conveying speed in the conveying direction 17 expediently has a component which corresponds to the direction and size of the speed in the conveying direction 14. As a result, the transition of the newspapers from section 11 to section 12 is particularly "gentle" and there is only a minimum degree of acceleration which results in forces acting on the newspaper.

Betrachtet man nun die Fig. 2 und 3, erkennt man das Ende des Abschnittes 12 des Förderers 10, der in einen Stapelschacht 18 mündet. Der Stapelschacht 18 ist seitlich durch Anschlagschienen 19,20,21 und 22 begrenzt. Der Boden des Stapelschachtes 18 wird durch einen Schieber 23 (oder durch ein Schieberpaar) gebildet, der in der Darstellung der Fig. 3 in einer zur Zeichenebene rechtwinkligen Richtung verschiebbar ist. Unter dem Schieber 23 ist ein eigentlicher Stapeltisch 24 angeordnet, der durch nicht näher dargestellte Mittel heb- und senkbar, sowie jeweils um 180° um eine lotrechte Achse verdrehbar ist.If one now looks at FIGS. 2 and 3, one can see the end of section 12 of conveyor 10, which opens into a stacking shaft 18. The stacking shaft 18 is laterally limited by stop rails 19, 20, 21 and 22. The bottom of the stacking shaft 18 is formed by a slider 23 (or by a pair of slides) which, in the illustration in FIG. 3, can be displaced in a direction perpendicular to the plane of the drawing. An actual stacking table 24 is arranged under the slider 23, which can be raised and lowered by means not shown, and can also be rotated by 180 ° about a vertical axis.

Das Ende des Abschnittes 12 ist gebildet durch einen Satz von drei an den Riemchenförderer 16 anschliessenden Einlaufriemen 25,26,27 (Fig. 3) mit je einem zugeordneten Andrückband 28,29,30, wobei jeder der Einlaufriemen mit dem zugeordneten Andrückband einen Förderspalt bildet, der die vom Riemchenförderer 16 übernommenen Zeitungen einklemmt und in der gleichen Lage weiterbefördert, also mit der einen Ecke voraus. Die Einlaufriemen 25 bis 27 sind mit derselben Geschwindigkeit wie der Riemchenförderer 16 angetrieben. Die Andrückbänder 28 bis 30 können ebenfalls mit derselben Geschwindigkeit angetrieben sein, oder aber auch frei umlaufend. Den Fig. 2 und 3 ist ferner zu entnehmen, dass die das Ende des aktiven Trums bildenden Umlenkrollen (nicht mit Ziffern bezeichnet) der Einlaufriemen 25 und 26, sowie der zugeordneten Andrückbänder 28 und 29 in unmittelbarer Nähe der Anschlagschiene 21 angeordnet sind und die Umlenkrollen des Einlaufriemens 27 und des Andrückbandes 30 in unmittelbarer Nähe der Anschlagschiene 22. Dies bietet Gewähr dafür, dass die zugeführten Zeitungen 15, die etwa in ihrer Diagonale festgeklemmt sind, in ihrem Schwerpunkt auch geführt sind bis unmittelbar bevor sie praktisch gleichzeitig mit ihren Seitenkanten an der Anschlagschiene 19 und an der rechtwinklig dazu angeordneten Anschlagschiene 20 anstossen, was bei einer herkömmlichen Zuführung gar nicht möglich ist. Damit sind also zwei rechtwinklig zueinander stehende Seitenkanten jeder zugeführten Zeitung 15 im sich bildenden Stapel durch zwei entsprechende Anschläge in ihrer Lage fixiert.The end of section 12 is formed by a set of three infeed belts 25, 26, 27 (FIG. 3) adjoining the apron conveyor 16, each with an associated pressure belt 28, 29, 30, each of the infeed belts forming a conveyor gap with the associated pressure belt , which jams the newspapers taken over by the strap conveyor 16 and conveys them in the same position, that is, with one corner ahead. The inlet belts 25 to 27 are driven at the same speed as the apron conveyor 16. The pressure belts 28 to 30 can also be driven at the same speed, or they can also rotate freely. 2 and 3 it can also be seen that the deflection rollers (not denoted by numerals) forming the end of the active run, the inlet belts 25 and 26, and the associated pressure belts 28 and 29 are arranged in the immediate vicinity of the stop rail 21 and the deflection rollers of the infeed belt 27 and the pressure belt 30 in the immediate vicinity of the stop rail 22. This ensures that the supplied newspapers 15, which are clamped approximately in their diagonal, are also guided in their center of gravity until immediately before they are practically simultaneously with their side edges on the Stop the stop rail 19 and the stop rail 20 arranged at right angles thereto, which is not possible with a conventional feeder. This means that two side edges of each newspaper 15 fed at right angles to one another are fixed in their position in the stack being formed by two corresponding stops.

Beide Umlenkrollen sowohl der Einlaufriemen 25 bis 27 als auch der Andruckbänder 28 bis 30 sind je in einem Rahmen 25′ und 27′ bzw. 28′,29′ und 30′ drehbar gelagert und diese Rahmen sind längs einer unteren bzw. einer oberen, quer verlaufenden Welle 31 bzw. 32 verschiebbar und feststellbar. Der Rahmen des Einlaufriemens 26 ist in Fig. 3 nicht sichtbar. Diese Verstellmöglichkeit gestattet eine sehr einfache Anpassung der Einrichtung an unterschiedliche Formate der anfallenden Flächengebilde.Both pulleys both the inlet belt 25 to 27 and the pressure belts 28 to 30 are each rotatably mounted in a frame 25 'and 27' or 28 ', 29' and 30 'and these frames are transverse to a lower or an upper extending shaft 31 and 32 displaceable and lockable. The frame of the inlet belt 26 is not visible in FIG. 3. This adjustment option allows a very simple adaptation of the device to different formats of the resulting flat structures.

Wenn beispielsweise Flächengebilde zu stapeln sind, die das in Fig. 2 mit dem strichpunktierten Umriss 15′ angedeutete Format haben, dann ist das Andrückband 30 mit dem zugeordneten Einlaufriemen 27 durch Verschiebung der Rahmen 30′ bzw. 27′ auf der Welle 32 bzw. 31 bis in die Stellung zu verschieben, die in Fig. 2 mit dem strichpunktierten Winkel 30˝ angedeutet ist. Sinngemäss dasselbe gilt für das Andrückband 29 mit dem zugehörigen Einlaufriemen 26 und für das Andrückband 28 mit dem zugehörigen Einlaufriemen 25, wobei für diese Elementenpaare die verschobenen Stellungen mit dem strichpunktierten Winkel 29˝ bzw. 28˝ angedeutet sind. Selbstverständlich sind auch die Anschlagschienen 19 bis 22 durch Verschiebung dem Format der anfallenden Flächengebilde anzupassen, wie das für Stapeleinrichtungen allgemein üblich ist. Vorteilhaft ist es, wenn die Längsmittellinie 17′ des Abschnittes 12 die Mittelachse 18′ des Stapelschachtes 18 schneidet, wie in Fig. 2 angegeben.If, for example, sheets are to be stacked, which is indicated in Fig. 2 with the dash-dotted outline 15 ' Have format, then the pressure belt 30 with the associated inlet belt 27 by moving the frame 30 'or 27' on the shaft 32 or 31 to move to the position indicated in Fig. 2 with the dash-dotted angle 30 ' . The same applies analogously to the pressure belt 29 with the associated inlet belt 26 and for the pressure belt 28 with the associated inlet belt 25, the shifted positions being indicated by the dash-dotted angle 29˝ or 28˝ for these element pairs. Of course, the stop rails 19 to 22 are also to be adjusted by displacement to the format of the resulting flat structures, as is common for stacking devices. It is advantageous if the longitudinal center line 17 'of section 12 intersects the central axis 18' of the stacking shaft 18, as indicated in Fig. 2.

Ausser den bereits beschriebenen, sind dem Stapelschacht 18 noch folgende Elemente zugeordnet. Es ist ein Satz Tragzinken 33 vorgesehen, die je mittels eines zugeordneten Pneumatik- oder Hydraulikzylinders 34 durch Längsöffnungen 35 in der Anschlagschiene 19 hindurchgreifend in den Stapelschacht 18 einfahrbar und aus diesem zurückziehbar sind. Die Zylinder 34 sind fest an einem Schlitten 36 montiert, der, geführt an Säulen 37, mittels zweier in Serie geschalteter Pneumatik- oder Hydraulikaggregate 38,39 vertikal verschiebbar ist. Sind beide Aggregate 38,39 voll ausgefahren, befinden sich die Zylinder 34 in der in Fig. 3 ausgezogen dargestellten Stellung oberhalb des Endes der Einlaufriemen 25 bis 27. Ist nur das Aggregat 38 eingezogen, das Aggregat 39 dagegen noch ausgefahren, befinden sich die Zylinder 34 und damit die Tragzinken 33 (falls ausgefahren) in der in Fig. 3 strichpunktiert und mit 33′ bezeichneten Stellung, unmittelbar unter dem Ende der Einlaufriemen 25 bis 27. Sind beide Aggregate eingezogen, sind die Zylinder 34 und damit auch die Tragzinken 33 in der in Fig. 3 ebenfalls strichpunktiert angegebenen Stellung in unmittelbarer Nähe oberhalb des Schiebers 23.In addition to those already described, the following elements are also assigned to the stacking shaft 18. A set of support tines 33 is provided, each of which can be inserted into and retracted from the stacking shaft 18 through longitudinal openings 35 in the stop rail 19 by means of an associated pneumatic or hydraulic cylinder 34. The cylinders 34 are fixedly mounted on a carriage 36 which, guided on columns 37, can be displaced vertically by means of two pneumatic or hydraulic units 38, 39 connected in series. If both units 38, 39 are fully extended, the cylinders 34 are in the position shown in solid lines in FIG. 3 above the end of the inlet belts 25 to 27. If only the unit 38 is retracted and the unit 39 is still extended, the cylinders are located 34 and thus the carrying tines 33 (if extended) in the dash-dotted line in FIG. 3 and designated 33 ', immediately below the end of the inlet belt 25 to 27. If both units are retracted, the cylinders 34 and thus also the carrying tines 33 in the in FIG. 3 also dot-dashed position in the immediate vicinity above the slide 23.

Zur Funktion der dargestellten Einrichtung:
   In Fig. 4a sind die Tragzinken 33 ausgefahren und in ihrer in Fig. 3 mit 33′ angedeuteten Stellung. Sie bilden damit eine vorübergehende Ablagefläche für die die Einlaufriemen 25 bis 27 und die Andrückbänder 28 bis 30 verlassenden Zeitungen 15, die gegen die Anschlagschienen 19 und 20 anschlagen. Der Schieber 23 ist offen und der bisher gebildete Teil S₁ eines Stapels ruht auf dem sich absenkenden Stapeltisch 24.About the function of the device shown:
In Fig. 4a, the carrying tines 33 are extended and in their position shown in Fig. 3 with 33 '. They thus form a temporary storage area for the newspapers 15 leaving the infeed belts 25 to 27 and the pressure belts 28 to 30, which strike against the stop rails 19 and 20. The slide 23 is open and the previously formed part S₁ of a stack rests on the lowering stacking table 24.

In Fig. 4b sind die Tragzinken 33 in die Nähe ihrer untersten Stellung angelangt und tragen einen weiteren Teil S₂ des zu bildenden Stapels. Die obere Seite des bereits gebildeten Teils S₁ ist inzwischen unter den Schieber 23 angelangt, der anschliessend in Schliessstellung gebracht worden ist. Der Stapeltisch 24 dreht sich nun um 180° um eine lotrechte Achse.In Fig. 4b, the carrying tines 33 have come close to their lowest position and carry a further part S₂ of the stack to be formed. The upper side of the already formed part S 1 has now reached under the slide 23, which has subsequently been brought into the closed position. The stacking table 24 now rotates through 180 ° about a vertical axis.

In Fig. 4c sind die Tragzinken 33 zurückgezogen und haben den immer noch in Bildung begriffenen Teil S₂ des Stapels auf dem nun geschlossenen Schieber 23 deponiert. Gleichzeitig wird der Stapeltisch 24 angehoben, so dass der darauf befindliche Teil S₁ des Stapels gegen die untere Seite des Schiebers 23 gedrückt wird, so dass er zusammengepresst wird.In Fig. 4c, the carrying tines 33 are withdrawn and have the part S₂ still in formation of the stack deposited on the now closed slide 23. At the same time, the stacking table 24 is raised, so that the part S 1 thereon of the stack is against the lower side of the slider 23 is pressed so that it is pressed together.

In Fig. 4d sind die Zylinder 34 und damit die Tragzinken 33 in ihre oberste Stellung verschoben und sodann sind die Tragzinken 33 wieder ausgefahren worden. Derweil geht die Vollendung des auf dem Schieber 23 ruhenden Teiles S₂ des Stapels vonstatten, während der Stapeltisch 24 mit dem nun verdrehten und verpressten Teil S₁ sich etwas abgesenkt hat.In Fig. 4d the cylinders 34 and thus the carrying tines 33 have been moved into their uppermost position and then the carrying tines 33 have been extended again. Meanwhile, the completion of the resting on the slide 23 part S₂ of the stack takes place, while the stacking table 24 with the now twisted and pressed part S₁ has lowered somewhat.

Sodann kann der Schieber 23 geöffnet werden und die Zinken in die Stellung 33′ abgesenkt werden und es ist wieder die Situation der Fig. 4a erreicht.Then the slide 23 can be opened and the tines are lowered into position 33 'and the situation of FIG. 4a is reached again.

Verstellt man in Fig. 3 die Enden der Einlaufriemen 25 und 27 mit jenen der zugeordneten Andrückbänder 28 und 30 auf eine etwas grössere Höhe als das Ende des Einlaufriemens 26 mit dem zugeordneten Andrückband 29, dann drückt man den in den Stapelschacht 18 in Richtung des Pfeiles 17 gelangenden Zeitungen 15 die in Fig. 5 ersichtliche Form auf. Diese Form besteht in einer Wölbung um zur Richtung 17 parallele Achsen. Diese Wölbung hat eine Versteifung der Zeitungen in Förderrichtung zur Folge.If the ends of the inlet belts 25 and 27 with those of the associated pressure belts 28 and 30 are adjusted in FIG. 3 to a somewhat greater height than the end of the inlet belt 26 with the associated pressure belt 29, then one presses them into the stacking shaft 18 in the direction of the arrow 17 arriving newspapers 15 in the form shown in FIG. 5. This shape consists of a curvature around axes parallel to the direction 17. This curvature causes the newspapers to stiffen in the direction of conveyance.

Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt. Der Stapelschacht und die diesem zugeordneten Elemente können auf irgendeine Weise ausgebildet sein, vorausgesetzt, dass der Stapelschacht seitlich durch mindestens ein Paar rechtwinklig zueinander stehende Anschlagschienen begrenzt ist, damit die Seitenkanten der Flächengebilde, die an deren Ecke angrenzen, mit welcher voraus die Flächengebilde den Stapelschacht erreichen, an diese Anschlagschienen praktisch gleichzeitig anschlagen und damit im sich bildenden Stapel ausgerichtet werden.The invention is not restricted to the exemplary embodiment described. The stacking shaft and the elements associated therewith can be designed in any way, provided that the stacking shaft is laterally delimited by at least one pair of stop rails which are perpendicular to one another, so that the side edges of the flat structures which adjoin the corner thereof advance the fabrics reach the stacking shaft, strike these stop rails practically simultaneously and are thus aligned in the stack being formed.

Die gewissermassen aufgefächerte Schuppenformation der Zeitungen 15 auf dem Abschnitt 12 ermöglicht ausserdem eine einwandfreie Zählung der Zeitungen 15 unmittelbar bevor sie in den Stapelschacht 18 gelangen. Diese Zählung kann beispielsweise mittels einer Lichtschranke erfolgen, deren Steuerstrahl - wie in Fig. 2 angedeutet - die Förderebene des Abschnittes 12 im Punkt 50 durchstösst. Wie auch immer der die Zählung bewirkende Zählimpulsgeber ausgebildet ist, wichtig ist, dass die Zählung unmittelbar vor dem Eintreffen in den Stapelschacht 18 erfolgt. Dies bedeutet, dass das Zählergebnis praktisch verzögerungsfrei den Istzustand im Stapelschacht 18 darstellt und dass allfällige Unregelmässigkeiten in der Schuppenformation auf dem Abschnitt 11 oder zu Beginn des Abschnittes 12 (z.B. durch eine entnommene Zeitung) das Zählergebnis nicht beeinflusst.The to some extent fanned-out scale formation of the newspapers 15 on the section 12 also enables the newspapers 15 to be counted correctly immediately before they reach the stacking shaft 18. This counting can take place, for example, by means of a light barrier, the control beam of which - as indicated in FIG. 2 - penetrates the conveying plane of section 12 at point 50. Whatever the form of the counting pulse generator, it is important that the counting takes place immediately before it arrives in the stacking shaft 18. This means that the counting result represents the actual state in the stacking shaft 18 practically without delay and that any irregularities in the scale formation on section 11 or at the beginning of section 12 (e.g. from a newspaper removed) do not influence the counting result.
