Description

Die Erfindung betrifft eine Vorrichtung zum Zentrieren eines Schuppenstromes aus Druckprodukten, mit einem angetriebenen Förderer, der wenigstens ein Transportorgan aufweist, welches den Schuppenstrom horizontal bewegt und mit einem an einem Abschnitt des Förderers angeordneten Gestell, an dem angetriebene Mittel zum seitlichen Ausrichten des Schuppenstromes vorgesehen sind, wobei diese Mittel eine erste in Transportrichtung gesehen seitlich links angeordnete Ausrichteinheit und eine zweite in Transportrichtung gesehen seitlich rechts angeordnete Ausrichteinheit aufweist.The invention relates to a device for centering a Shingled stream of printed products, with a driven Conveyor having at least one transport member, which the shingled stream moves horizontally and with one at a section the conveyor arranged frame on the driven Means provided for the lateral alignment of the scale flow are, these means a first in the transport direction seen laterally arranged left alignment unit and a second seen in the transport direction laterally arranged right Aligning unit has.

Vorrichtungen der genannten Art kommen insbesondere im Bereich der Druckweiterverarbeitung zum Einsatz. Beispielsweise dienen sie zum Beschicken von Rotationsschneidern, Stangenauslegern, Kreuzlegern und dergleichen mit Druckprodukten. Die Einzelprodukte des Schuppenstroms können auch unbedruckte und einzeln gefaltete oder ungefaltete Blätter sein.Devices of the type mentioned come especially in the field the print finishing used. For example, serve for feeding rotary cutters, bar jibs, Crosslaid and the like with printed products. The individual products The scale flow can also be unprinted and individually be folded or unfolded leaves.

Eine Vorrichtung der genannten Art ist aus der US 4,015,843 bekannt geworden. Diese dient zum Zentrieren eines Schuppenstromes aus Zeitungen. An einem Gestell sind seitlich um Rollen gelegte endlose Bänder angeordnet. Diese Bänder bilden einen trichterförmigen Einlaufbereich, in dem ungeordnete Druckprodukte des Schuppenstromes erfasst und zentriert werden. Für höhere Geschwindigkeiten ist diese Vorrichtung nicht geeignet.A device of the type mentioned is known from US 4,015,843 known. This serves to center a scale flow from newspapers. On a frame are laterally around rollers arranged endless bands arranged. These bands form one funnel-shaped inlet area, in the disordered printed products of the scale flow are detected and centered. For higher speeds, this device is not suitable.

Durch die DE 31 13 399 A ist eine Vorrichtung bekannt geworden, bei der die horizontale Führung durch Transportbänder erfolgt, die zumindest teilweise quer zur Transportrichtung verschiebbar angeordnet sind und mittels einer Stelleinrichtung zusammen mit einem benachbarten äusseren Transportorgan verstellbar sind. Die vertikale Führung erfolgt durch seitliche Anschlagleisten, die ebenfalls trichterförmig angeordnet werden können.From DE 31 13 399 A a device has become known in which the horizontal guidance is made by conveyor belts, at least partially displaceable transversely to the transport direction are arranged and by means of an adjusting device adjustable together with a neighboring outer transport organ are. The vertical guidance is made by lateral Stop strips, which are also arranged funnel-shaped can.

Durch die DE 32 21 601 A ist eine Vorrichtung bekannt geworden, bei der der Schuppenstrom zentriert wird, indem dieser während seiner Förderung seitlich durch bewegliche Wände beaufschlagt wird, welche in Förderrichtung des Schuppenstroms zueinander konvergierend angeordnet sind. Die horizontale Führung erfolgt auch hier mittels endlosen Bändern.From DE 32 21 601 A a device has become known in which the scale flow is centered by this during its promotion applied laterally by movable walls is, which in the conveying direction of the scale flow are arranged converging to each other. The horizontal leadership also takes place here by means of endless bands.

Durch die EP 0 223 941 A ist eine Vorrichtung bekannt geworden, bei welcher der Schuppenstrom durch seitliche Bänder zentriert wird. Diese Bänder sind zur Anpassung an die jeweilige Breite des Schuppenstromes im Abstand zueinander verstellbar gelagert.EP 0 223 941 A has disclosed a device in which the scale flow through lateral bands is centered. These tapes are for adaptation to the respective ones Width of the scale flow in the distance adjustable stored.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die kostengünstiger herstellbar ist und mit der auch bei vergleichsweise hohen Fördergeschwindigkeiten ein Schuppenstrom zentriert werden kann. Das Zentrieren soll auch dann zuverlässig erfolgen, wenn der Produkteversatz vergleichsweise gross ist.The invention is based on the object, a device of to create said type, which is cheaper to produce and with the even at relatively high conveying speeds a scale flow can be centered. The centering should also be reliable, if the product offset is comparatively large.

Die Aufgabe ist bei einer erfindungsgemässen Vorrichtung dadurch gelöst, dass Mittel vorgesehen sind, welche den Schuppenstrom von unten auflockern.
Es hat sich gezeigt, dass ein solches Auflockern den Zentriervorgang überraschend wirksam unterstützt, und zwar auch bei höheren Geschwindigkeiten, beispielsweise bei einer Durchlaufgeschwindigkeit von 1 m/s oder mehr.
Insbesondere erfolgt das Auflockern durch Rütteln des Schuppenstromes. Der Schuppenstrom wird somit von unten aufgerüttelt und damit aufgelockert. Dies kann konstruktiv mit sehr einfachen und robusten Teilen erfolgen.The object is achieved in a device according to the invention in that means are provided which loosen the scale flow from below.
It has been found that such a loosening supports the centering surprisingly effective, even at higher speeds, for example at a flow rate of 1 m / s or more.
In particular, the loosening is done by shaking the scale flow. The scale flow is thus shaken up from below and loosened up. This can be done constructively with very simple and robust parts.

Nach einer Weiterbildung der Erfindung erfolgt das Auflockern durch Erhebungen des Transportorgans.
Insbesondere sind diese Erhebungen an Transportrollen angeordnet, die sich quer zur Transportrichtung erstrecken.
Das Auflockern erfolgt vorzugsweise bereits im Einlaufbereich oder vor diesem Einlaufbereich.According to a development of the invention, the loosening is carried out by elevations of the transport member.
In particular, these elevations are arranged on transport rollers which extend transversely to the transport direction.
The loosening is preferably carried out already in the inlet area or in front of this inlet area.

Eine besonders wirksame Zentrierung bei hohen Geschwindigkeiten wird dann erreicht, wenn gemäss einer Weiterbildung der Erfindung die beiden Ausrichteinheiten in Förderrichtung gesehen zuerst einen Einlaufbereich und anschliessend einen Beruhigungsbereich bilden.
Der Einlaufbereich weist gemäss einer Weiterbildung der Erfindung angetriebene vertikale Rollen auf, über welche wenigstens ein endloses Band geführt ist. Dieser Einlaufbereich ist vorzugsweise trichterförmig ausgebildet.A particularly effective centering at high speeds is achieved if, according to an embodiment of the invention, the two alignment units, viewed in the conveying direction, first form an inlet area and then a calming area.
The inlet region has, according to an embodiment of the invention driven vertical rollers over which at least one endless belt is guided. This inlet region is preferably funnel-shaped.

Nach einer Weiterbildung der Erfindung weist der Beruhigungsbereich mehrere vertikale Rollen auf, die wenigstens bereichsweise frei sind, sodass der Schuppenstrom in diesem Beruhigungsbereich direkt an diesen vertikalen Rollen geführt ist. Zwischen diesen vertikalen Rollen ist das Transportorgan frei, es sind somit hier weder Bänder noch Leitbleche vorhanden. Die Rollen sind rund ausgeführt und keine Exzenter. Somit erhält der Schuppenstrom im Beruhigungsbereich keine seitliche Rüttelbewegung, sondern wird kontinuierlich seitlich ausgerichtet. Versuche haben ergeben, dass seitliche Bänder im Beruhigungsbereich verhindern würden, dass sich allenfalls aufstehende Ecken der Einzelprodukte wieder ablegen können. Sind die Einzelprodukte in diesem Beruhigungsbereich an vertikalen Rollen geführt, so können sich solche aufstehende Produkteecken wieder legen. Vorzugsweise erfolgt auch im Einlaufbereich keine seitliche Rüttelbewegung, sondern lediglich ein Auflockern von unten.According to a development of the invention, the calming area several vertical roles, at least partially are free, so the scale flow in this calming area is guided directly on these vertical rollers. Between these vertical rollers, the transport organ is free, There are thus neither bands nor baffles available here. The Rolls are round and no eccentric. Thus receives the scale flow in the calming area no lateral shaking movement, but is continuously aligned laterally. Experiments have shown that lateral ligaments in the calming area would prevent that at most stand up Can take off corners of the individual products again. Are the Individual products in this calming area on vertical rollers led, so can such upstanding products corners lay it down again. Preferably, no takes place in the inlet area lateral shaking movement, but only a loosening from underneath.

Zur horizontalen Führung ist ein Förderer 4 vorgesehen, der ein Transportorgan 5 aufweist, welches mehrere angetriebene Transportrollen 14 besitzt. Diese Transportrollen 14 sind an seitlichen Lagerschienen 23 drehbar gelagert und von einem hier nicht gezeigten Antriebsorgan so angetrieben, dass sämtliche Transportrollen 14 in gleicher Richtung und Geschwindigkeit um ihre Achse 17 (Figur 4) drehen. Wie die Figur 4 zeigt, sind die Rollen 14 jeweils im Abstand zueinander angeordnet. Zwischen benachbarten Rollen besteht somit ein Zwischenraum. Die Rollen 14 sind in Richtung des Pfeils 19 angetrieben, wie die Figur 4 zeigt. Die Figuren 1 und 2 zeigen lediglich einen Abschnitt des Förderers 4, der den Schuppenstrom 2 der Vorrichtung 1 zu- und von dieser wieder wegführt.The device 1 shown in Figure 1 is used for promotion and Centering of the scale flow 2 shown in FIG Direction of the arrow 18. For horizontal guidance is a conveyor 4 is provided, which has a transport member 5, which has multiple driven transport rollers 14. These transport wheels 14 are rotatably mounted on lateral bearing rails 23 and driven by a drive member, not shown here, that all transport rollers 14 in the same direction and speed around its axis 17 (Figure 4). As FIG. 4 shows, the rollers 14 are each at a distance arranged to each other. Between adjacent roles exists thus a gap. The rollers 14 are in the direction of Arrow 19 driven, as Figure 4 shows. The figures 1 and Fig. 2 only show a portion of the conveyor 4 which the scale flow 2 of the device 1 to and from this again leads away.

Das Transportorgan 5 ist auf einem Gestell 6 befestigt, das in einem Abschnitt des Förderers 4 angeordnet ist.The transport member 5 is mounted on a frame 6, which in a portion of the conveyor 4 is arranged.

Am Gestell 6 sind zudem zwei Ausrichteinheiten 8 und 9 gelagert. In Transportrichtung gesehen befindet sich die Ausrichteinheit 8 auf der linken Seite und die Ausrichteinheit 9 auf der rechten Seite des Förderers 4. Die beiden Ausrichteinheiten 8 und 9 besitzen jeweils eine Lagerplatte 13, an der unterseitig mehrere vertikale Rollen 10 und 11 gelagert sind. Diese Rollen 10 und 11 sind jeweils im Abstand zueinander angeordnet und ebenfalls angetrieben. Der Antrieb kann hier derjenige sein, welcher das Transportorgan 5 bzw. die Transportrollen 14 antreibt. Die beiden Ausrichteinheiten 8 und 9 bilden Mittel 7 zum Zentrieren des Schuppenstroms 2 und sind spiegelbildlich ausgebildet.On frame 6 also two alignment units 8 and 9 are mounted. When viewed in the transport direction, the alignment unit is located 8 on the left side and the alignment unit 9 on the right side of the conveyor 4. The two alignment units 8 and 9 each have a bearing plate 13, on the underside a plurality of vertical rollers 10 and 11 are stored. These rollers 10 and 11 are each arranged at a distance from each other and also powered. The drive can be the one here be, which the transport member 5 and the transport rollers 14 drives. The two alignment units 8 and 9 form Means 7 for centering the scale flow 2 and formed mirror image.

Die Transportrollen 11 sind in einem Einlaufbereich E angeordnet und laufen in Richtung des Pfeiles 18 gesehen konisch zusammen. Der Einlaufbereich E ist somit trichterförmig ausgebildet. Die beiden Ausrichteinheiten 8 und 9 besitzen jeweils ein endloses Band 12, das um die Rollen 11 geführt ist. Die Bänder 12 sind wie ersichtlich in einem unteren Bereich der vertikalen Rollen 11 und somit unmittelbar über den Transportrollen 14 angeordnet. Die Bänder 12 sind über die Rollen 11 angetrieben und wirken mit dem Schuppenstrom 2 zusammen.The transport rollers 11 are arranged in an inlet region E. and converge conically as viewed in the direction of the arrow 18. The inlet region E is thus funnel-shaped. The two alignment units 8 and 9 each have an endless belt 12, which is guided around the rollers 11. The Bands 12 are as shown in a lower portion of the vertical rollers 11 and thus immediately above the transport rollers 14 arranged. The bands 12 are on the rollers 11th driven and cooperate with the scale flow 2.

Die vertikalen Rollen im Beruhigungsbereich B sind frei, d.h. ohne Band oder Leitblech. Der Raum zwischen den vertikalen Rollen 10 der linken Ausrichteinheit 8 und den Rollen 10 der rechten Ausrichteinheit 9 ist somit frei. Der Bereich ist zudem nicht mehr trichterförmig bzw. konisch, sondern die Abstände zwischen gegenüberliegenden vertikalen Rollen 10 sind im Wesentlichen gleich. Ein leicht konischer Verlauf ist hier jedoch denkbar.The vertical rollers in the calming area B are free, i. without tape or baffle. The space between the vertical Rolls 10 of the left alignment unit 8 and the rollers 10 of the right alignment unit 9 is thus free. The area is also no longer funnel-shaped or conical, but the distances between opposite vertical rollers 10 are essentially the same. A slightly conical course is here however conceivable.

Die Figur 2 zeigt schematisch die Zentrierung des Schuppenstromes 2 durch die Vorrichtung 1. Die in Figur 2 gezeigten Einzelprodukte 3a des Schuppenstromes 2 sind ungeordnet. Der seitliche Versatz der Einzelprodukte 3a kann hier bis etwa +/- 20 mm betragen. Am Ausgang der Vorrichtung sind Einzelprodukte 3b des Schuppenstromes 2 weitgehend zentriert, d.h. die Fusskanten 21 und Kopfkanten 22 nachfolgender Einzelprodukte 3 verlaufen jeweils parallel zueinander. Das Zentrieren bzw. Ausrichten der Einzelprodukte 3a erfolgt im Einlaufbereich E durch die angetriebenen seitlichen Bänder 12. Dieses Zentrieren bzw. seitliche Ausrichten wird durch ein Auflockern des Schuppenstromes 2 im Einlaufbereich E wesentlich unterstützt.FIG. 2 shows schematically the centering of the scale flow 2 through the device 1. The shown in Figure 2 Individual products 3a of the scale flow 2 are disordered. Of the lateral offset of the individual products 3a can here until about +/- 20 mm. At the output of the device are individual products 3b of the scale flow 2 is largely centered, i. the foot edges 21 and top edges 22 of the following individual products 3 each run parallel to each other. Centering or Alignment of the individual products 3a takes place in the inlet area E through the driven lateral bands 12. This centering or lateral alignment is by loosening the Schuppenstromes 2 significantly supported in the inlet area E.

Das Auflockern des Schuppenstromes 2 insbesondere im Einlaufbereich E erfolgt durch Mittel 15, die an wenigstens einer der Transportrollen 14 angeordnet sind. Diese Mittel 15 weisen gemäss Figur 4 Erhebungen 16 auf, die wie ersichtlich mittig angeordnet sind und die sich in Längsrichtung der Rollen 14 erstrecken. Wie die Figur 1 zeigt, weisen nicht sämtliche Transportrollen 14 solche Mittel 15 auf. Zwischen Rollen 14 mit jeweils einem Mittel 15 können somit auch Rollen 14a ohne solche Mittel 15 angeordnet sein. Dies ist ebenfalls in Figur 4 gezeigt. Grundsätzlich ist aber auch eine Anordnung denkbar, bei welcher sämtliche Rollen 14 mit solchen Mitteln 15 versehen sind. Denkbar ist auch eine Ausführung, bei welcher die Mittel 15 nicht an Transportrollen 14, sondern an anderen, nicht transportierenden Rollen oder dergleichen angeordnet sind.The loosening of the scale flow 2 in particular in the inlet region E is performed by means 15, which at least one of Transport rollers 14 are arranged. These means 15 have according to Figure 4 surveys 16, as shown centered are arranged and extending in the longitudinal direction of the rollers 14th extend. As Figure 1 shows, not all Transport roles 14 such means 15 on. Between rollers 14 each with a means 15 can thus also rollers 14a without such means 15 may be arranged. This is also in FIG 4. Basically, however, an arrangement is conceivable in which all rollers 14 are provided with such means 15 are. Also conceivable is an embodiment in which the Means 15 not on transport rollers 14 but on others, not transporting rollers or the like arranged are.

Die Mittel 15 sind drehfest an den Rollen 14 befestigt. Die Befestigung kann beispielsweise mit einem Band 24 erfolgen, wie dies in Figur 4 angedeutet ist. Die Erhebungen 16 sind hier Rippen, die sich in Längsrichtung der Rollen 14 erstrecken. Es sind hier aber auch andere Erhebungen, beispielsweise Nocken, Zähne und dergleichen denkbar. In der Figur 4 sind jeweils drei Erhebungen 16 an einer Rolle 14 angeordnet. Die Abstände zwischen den Erhebungen 16 einer Rolle sind gleich. Es ist auch eine Ausführung denkbar, bei welcher weniger oder mehr als drei solche Erhebungen 16 angeordnet sind. Die Erhebungen 16 einer Transportrolle 14 können unterschiedlich ausgebildet sein. Zudem können die äusseren Eingriffsflächen der Erhebungen 16 uneben, beispielsweise gerippt oder aufgerauht sein. Die in Figur 4 gezeigte Höhe H der Erhebungen 16 ist von dem zu zentrierenden Schuppenstrom 2 bzw. den Einzelprodukten 3 abhängig. Die Höhe H beträgt beispielsweise einige Millimeter, beispielsweise 1 bis 5 mm. Diese Erhebungen 16 schlagen gemäss Figur 4 mittig an die Unterseite 20 der Einzelprodukte 3 und dadurch wird der Schuppenstrom 2 mittels einer Rüttelbewegung vertikal von unten aufgelockert. Durch diese Rüttelbewegung bzw. Auflockerung wird die Reibung zwischen der Unterseite 20 und einer Oberseite 25 sich überlappender Einzelprodukte 3 vermindert. Die aufgelockerten Druckprodukte 3 können sich somit leichter und mit kleinerer Kraft quer zur Transportrichtung verschieben. Insbesondere im Einlaufbereich E ist damit auch bei höheren Geschwindigkeiten eine zuverlässige Zentrierung bzw. Ausrichtung möglich.The means 15 are rotatably attached to the rollers 14. The Attachment can be done for example with a band 24, as indicated in Figure 4. The elevations 16 are here ribs which extend in the longitudinal direction of the rollers 14. But there are other surveys, for example Cams, teeth and the like conceivable. In the figure 4 are respectively three elevations 16 arranged on a roller 14. The distances between the elevations 16 of a roll are the same. It is also an embodiment conceivable in which less or more than three such surveys 16 are arranged. The surveys 16 of a transport roller 14 may be formed differently be. In addition, the outer engagement surfaces of the Elevations 16 uneven, for example ribbed or roughened be. The height H of the elevations 16 shown in FIG. 4 is from the shingled stream 2 or the individual products to be centered 3 dependent. The height H is for example a few millimeters, for example 1 to 5 mm. Beat these surveys 16 according to FIG 4 centered on the underside 20 of the individual products 3 and thereby the scale flow 2 by means of a shaking movement loosened vertically from below. Through this shaking movement or loosening is the friction between the bottom 20 and a top 25 overlapping individual products 3 decreased. The loosened printed products 3 can thus easier and with less force across the transport direction move. In particular, in the inlet region E is so that even at higher speeds a reliable Centering or alignment possible.

Da die Mittel 15 wie ersichtlich mittig der Transportrollen 14 angeordnet sind, wird der Schuppenstrom 2 entlang einer Mittellinie aufgelockert. Die Rüttelbewegung pflanzt sich von dieser Mittellinie beidseitig nach aussen fort und mindert damit die genannte Reibung im gesamten Überlappungsbereich. Die Mittel 15 können auch von der Mitte des Schuppenstroms 2 seitlich versetzt angeordnet sein.Since the means 15 as shown in the middle of the transport rollers 14th are arranged, the scale flow 2 along a center line loosened. The shaking movement is planted by this center line on both sides to the outside and thus reduces the said friction in the entire overlap area. The Means 15 can also be from the middle of the scale flow 2 laterally be arranged offset.
