Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Vergleichmässigen des Abstandes zwischen aufeinanderfolgenden, in einer Schuppenformation anfallenden, biegsamen, flächigen Produkten, insbesondere Druckereierzeugnissen, gemäss Oberbegriff des Anspruches 1.The present invention relates to a device for equalizing the distance between successive, flexible, flat products, which occur in a scale formation, in particular printed products, according to the preamble of claim 1.

Eine Vorrichtung zum Vergleichmässigen des Schuppenabstandes dieser Art ist aus der DE-A 3 148 349 bekannt. Bei dieser Vorrichtung wird die Schuppenformation mittels eines Bandförderers schrittweise vorgeschoben, wobei während jedem Vorschubschritt Anschlagfinger in den Förderweg der Schuppenformation hineinbewegt werden. Die Druckbogen kommen dabei mit ihrer vorlaufenden Kante an den Anschlagfingern zum Anstossen, wodurch sie an ihrer weitem Vorwärtsbewegung gehindert werden. Am Ende jedes Vorschubschrittes werden die Anschlagfinger wieder aus dem Förderweg herausbewegt. Die Bewegung der Anschlagfinger wird mittels Steuerscheiben gesteuert.A device for evening the scale spacing of this type is known from DE-A 3 148 349. In this device the scale formation is advanced step by step by means of a belt conveyor, with stop fingers being moved into the conveying path of the scale formation during each advance step. The leading edges of the printed sheets come into contact with the stop fingers, thereby preventing them from moving far forward. At the end of each feed step, the stop fingers are moved out of the conveyor path again. The movement of the stop fingers is controlled by means of control disks.

Nach Freigabe der Druckbogen durch die Anschlagfinger müssen erstere aus dem Stillstand beschleunigt und über eine gewisse Strecke vorgeschoben werden, bevor sie in einen durch Förderräder und den Bandförderer gebildeten Förderspalt eintreten können. Während dieses Vorschiebens besteht nun die Gefahr, dass sich der jeweils freigegebene Druckbogen gegenüber dem vorauslaufenden Druckbogen verschiebt, was zu einer unerwünschten Veränderung des vorgängig ausgeglichenen Schuppenabstandes führen kann. Diese Gefahr erhöht sich mit zunehmender Fördergeschwindigkeit.After the release sheet has been released by the stop fingers, the former must be accelerated from standstill and advanced over a certain distance before they can enter a conveyor gap formed by conveyor wheels and the belt conveyor. During this advance there is now a risk that the respectively released printed sheet will shift relative to the preceding printed sheet, which can lead to an undesirable change in the previously balanced scale spacing. This danger increases with increasing conveyor speed.

Aus der DE-A 2 922 450 ist eine Vorrichtung zum Wegfördern von in Schuppenformation anfallenden Druckereierzeugnissen bekannt, welche einen Bandförderer aufweist, der die Schuppenformation mit horizontaler Förderrichtung einem Förderer zuführt, welcher in Förderrichtung hintereinander angeordnete Greifer zum Erfassen der zugeführten Druckereierzeugnisse an deren vorlaufenden Kante aufweist. Die Förderrichtung des Förderers verläuft quer zur Förderrichtung des vorgeschalteten Bandförderers, das heisst von unten nach oben. Um sicherzustellen, dass die zugeführten Druckereierzeugnisse im Uebernahmebereich einwandfrei in die offenen Greifer einlaufen, ist am Ende des Bandförderers ein mit dessen Umlenkrolle mitdrehendes Rad vorgesehen, das mit Auslenknocken versehen ist. Diese Auslenknocken wirken auf die Vorderkante der ankommenden Druckprodukte ein und heben diese leicht an, wodurch ein sicheres Erfassen der Druckereiprodukte durch die Greifer erfolgt. Um zu verhindern, dass viel zu früh bzw. viel zu spät ankommende Druckereierzeugnisse gegen eine Klemmbacke eines Greifers anstossen, ist dieses Rad mit Anschlagfingem versehen, an denen ein nicht im Takt mit den Greifern zum Uebernahmebereich gelangendes Druckereierzeugnis anstösst und an seiner Weiterbewegung gehindert wird. Die Druckereierzeugnisse werden durch die Anschlagfinger solange zurückgehalten, bis sie durch einen Auslenknocken über den Anschlagfinger angehoben und zur Weiterförderung zum nächsten Greifer freigegeben werden. Diese Anschlagfinger kommen nur zur Wirkung bei bezüglich der Greiferfolge viel zu früh bzw. viel zu spät zum Uebernahmebereich gelangenden Druckereierzeugnissen. Eine Vergleichmässigung des Abstandes zwischen aufeinanderfolgenden Druckereierzeugnissen wird nicht angestrebt, da die Anschlagfinger bei nur leicht unterschiedlichem Schuppenabstand nicht wirksam werden.From DE-A 2 922 450 a device for conveying away printed products resulting in scale formation is known, which has a belt conveyor which feeds the scale formation with a horizontal conveying direction to a conveyor which grippers arranged one behind the other in the conveying direction for gripping the supplied printed products on their leading edge having. The conveying direction of the conveyor runs transversely to the conveying direction of the upstream belt conveyor, that is, from bottom to top. In order to ensure that the printed products fed into the takeover area run smoothly into the open grippers, a wheel which rotates with its deflection roller and is provided with deflection cams is provided at the end of the belt conveyor. These deflecting cams act on the front edge of the incoming printed products and lift them up slightly, as a result of which the grippers securely grasp the printed products. In order to prevent printed products that arrive much too early or too late from hitting a jaw of a gripper, this wheel is provided with stop fingers against which a printed product that does not come in line with the grippers to the transfer area hits and is prevented from moving on. The printed products are held back by the stop fingers until they are lifted over the stop fingers by a deflection cam and released for further conveyance to the next gripper. These stop fingers only come into effect in the case of printed products that arrive far too early or far too late with respect to the gripper sequence. The aim is not to even out the distance between successive printed products, since the stop fingers do not become effective if the scale spacing is only slightly different.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, welche es erlaubt, auch bei verhältnismässig hohen Fördergeschwindigkeiten den genau auf einen bestimmten Wert einzustellen.The present invention is based on the object of creating a device of the type mentioned at the outset which makes it possible to set the device precisely to a certain value even at relatively high conveying speeds.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Der Weitertransport der durch die Anschlaganordnung an ihrer weiteren Vorwärtsbewegung gehinderten Produkte wird durch die Mitnehmeranordnung veranlasst, die genau im gewünschten Takt auf die an der Anschlaganordnung anstehenden Produkte einwirkt und durch Auslenken deren Vorbeibewegung an der Anschlaganordnung auslöst.The further transport of the products which are prevented from moving further forward by the stop arrangement is initiated by the driver arrangement, which acts on the products in contact with the stop arrangement at exactly the desired cycle and triggers their movement past the stop arrangement by deflection.

Damit werden die Produkte hinter der Anschlaganordnung im jeweils richtigen Zeitpunkt von der hinteren Fördereinrichtung erfasst und von dieser zusammen mit den vorauslaufenden Produkten weggefördert. Dies bedeutet, dass der Abstand zwischen aufeinanderfolgenden Produkten im wesentlichen immer der gewünschten Sollgrösse entspricht.In this way, the products behind the stop arrangement are grasped by the rear conveyor at the right time in each case and conveyed away by this together with the preceding products. This means that the distance between successive products essentially always corresponds to the desired target size.

Bevorzugte Weiterausgestaltungen der beanspruchten Vorrichtung bilden Gegenstand der abhängigen Ansprüche.Preferred further developments of the claimed device form the subject of the dependent claims.

Im folgenden werden an Hand der Zeichnung Ausführungsbeispiele des Erfindungsgegenstandes näher erläutert. Es zeigt rein schematisch:

Wie insbesondere aus den Fig. 1 und 3 hervorgeht, ist eine Förderanordnung 1 vorhanden, die durch zwei Bandförderer 2, 3 sind in deren Förderrichtung A bzw. B gesehen hintereinander angeordnet, wobei der hintere Bandförderer 3 gegenüber dem vorgeschalteten Bandförderer 2 eine schräg nach abwärts gerichtete Förderrichtung B aufweist. Beide Bandförderer 2, 3 werden von einer in Fig. 1 nur schematisch dargestellten Antriebswelle 4 her angetrieben, die auf nicht näher dargestellte Weise im Uhrzeigersinn umlaufend angetrieben wird. Diese Drehbewegung der Antriebswelle 4 wird über nur schematisch dargestellte Ketten 5 und 6 auf die Umlenkwalzen 7 und 8 der Bandförderer 2, 3 übertragen. Die Umlaufgeschwindigkeit und somit die Fördergeschwindigkeit der Bandförderer 2, 3 ist mit vi, vo bezeichnet. Der förderwirksame (s. Fig. 1) Trum 3a des hinteren Bandförderes 3 läuft über ein geneigt angeordnetes Stützblech 9.As can be seen in particular from FIGS. 1 and 3, a conveyor arrangement 1 is provided, which are arranged one behind the other by two belt conveyors 2, 3 as seen in the direction of their conveyance A and B, the rear belt conveyor 3 being inclined downwards relative to the upstream belt conveyor 2 directional conveying direction B. Both belt conveyors 2, 3 are driven by a drive shaft 4 shown only schematically in FIG. 1, which is driven in a clockwise direction in a manner not shown in detail. This rotary movement of the drive shaft 4 is via chains 5 and 6, only shown schematically, to the deflection rollers 7 and 8 of the belt conveyors 2, 3. The rotational speed and thus the conveying speed of the belt conveyors 2, 3 is denoted by v i , v o . The conveying (see FIG. 1) strand 3a of the rear belt conveyor 3 runs over an inclined support plate 9.

Die beiden Bandförderer 2, 3 sind in einem Abstand voneinander angeordnet, durch den eine förderunwirksame Strecke 10 festgelegt wird. Wie die Fig 1 und 3 zeigen, sind in dieser förderunwirksamen Strecke 10 frei drehbar gelagerte Rollen 11 angeordnet. Anstelle dieser Rollen 11 könnte auch ein Stützblech vorgesehen werden.The two belt conveyors 2, 3 are arranged at a distance from one another, by means of which an ineffective path 10 is defined. As FIGS. 1 and 3 show, freely rotatably mounted rollers 11 are arranged in this ineffective section 10. Instead of these rollers 11, a support plate could also be provided.

Oberhalb des hinteren Bandförderers 3 ist eine Anschlaganordnung 12 sowie eine Mitnehmeranordnung 13 vorhanden. Die Mitnehmeranordnung 13 vorhanden. Die Mitnehmeranordnung 13 wird durch zwei in einem Abstand voneinander angeordnete Mitnahmeräder 14, 15 (Fig. 2) gebildet. Jedes dieser Mitnahmeräder 14, 15 ist an seinem Umfang mit abstehenden Mitnahmenocken 16 versehen, die in Umfangsrichtung gleichmässig verteilt angeordnet sind.Above the rear belt conveyor 3 there is a stop arrangement 12 and a driver arrangement 13. The driver arrangement 13 is present. The driver arrangement 13 is formed by two driver wheels 14, 15 arranged at a distance from one another (FIG. 2). Each of these driving wheels 14, 15 is provided on its circumference with projecting driving cams 16 which are arranged in a uniformly distributed manner in the circumferential direction.

Die Mitnahmeräder 14, 15 sitzen auf einer Welle 17, welche in zwei Schwenkhebeln 18 und 19 gelagert ist, wie das insbesondere aus Fig. 2 hervorgeht. An ihrem andern Ende sind die Schwenkhebel 18, 19 schwenkbar auf einer Welle 20 gelagert, die in einem Rahmen 21 (Fig. 1) gelagert ist. Die Welle 20 verläuft etwa parallel zur durch den Bandförderer 2 festgelegten Förderebene und im wesentlichen rechtwinklig zur Förderrichtung A. Die Welle 20 wird von der Umlenkwalze 7 des vorderen Bandförderers 2 her über eine nur schematisch dargestellte Kette 22 im Gegenuhrzeigersinn angetrieben. Auf der Welle 20 sitzt ein Kettenrad 23, das in Richtung des Pfeiles C (Fig. I) dreht. Mit diesem Kettenrad 23 ist eine Kette 24 im Eingriff, die über ein zweites Kettenrad 25 geführt ist, das auf der Welle 17 sitzt. Die Kette 24 wird mittels eines Spannrades 26 gespannt gehalten. Ueber die Kette 24 werden somit die beiden Mitnahmeräder 14, 15 in Richtung des Pfeiles D (Fig. I und 3) umlaufend angetrieben. Die Umfangsgeschwindigkeit v2 dieser Mitnahmeräder 14, 15 ist im wesentlichen gleich der Fördergeschwindigkeit vo des Bandförderers 3. Die beiden Schwenkhebel 18 und 19 sind mittels eines Querträgers 27 miteinander verbunden. An diesem Querträger ist ein L-förmiges Halteelement 28 befestigt, das in Längsrichtung des längeren Schenkels, d.h. in Richtung des Pfeiles E, längsverschiebbar ist. Mittels einer mit 29 bezeichneten Arretierschraube kann das Halteelement 28 in seiner Lage fixiert werden. Am kürzeren Schenkel des Halteelementes 25 ist ein ebenfalls L-förmiger Träger 30 gehalten, der an seinem freien Ende einen nach unten abstehenden Anschlag 31 aufweist, der mit dem Träger 30 einstückig ausgebildet ist. Der Anschlag 31 endet in einem Abstand vom förderwirksamen Trum 3a des hinteren Bandförderers 3 und legt mit diesem einen Druchtrittsspalt 32 fest. Die Grösse dieses Durchtrittsspaltes 32 kann durch Verschieben des Trägers 30 in Richtung des Pfeiles F verändert werden. Zur Arretierung des Trägers 30 ist eine weitere Arretierschraube 29' vorgesehen. Am Anschlag 31 ist ein in Förderrichtung A,B gesehen nach hinten weisendes Leitblech 33 angebracht.The driving wheels 14, 15 sit on a shaft 17 which is mounted in two pivot levers 18 and 19, as can be seen in particular from FIG. 2. At its other end, the pivot levers 18, 19 are pivotally mounted on a shaft 20 which is mounted in a frame 21 (FIG. 1). The shaft 20 runs approximately parallel to the conveying plane defined by the belt conveyor 2 and essentially at right angles to the conveying direction A. The shaft 20 is driven counterclockwise by the deflection roller 7 of the front belt conveyor 2 via a chain 22, only shown schematically. A sprocket 23 is seated on the shaft 20 and rotates in the direction of the arrow C (FIG. I). With this sprocket 23, a chain 24 is engaged, which is guided over a second sprocket 25, which sits on the shaft 17. The chain 24 is held under tension by means of a tensioning wheel 26. Via the chain 24, the two drive wheels 14, 15 are thus driven in a rotating manner in the direction of the arrow D (FIGS. I and 3). The peripheral speed v 2 of these driving wheels 14, 15 is substantially equal to the conveying speed vo of the belt conveyor 3. The two pivot levers 18 and 19 are connected to one another by means of a cross member 27. An L-shaped holding element 28 is fastened to this cross member and is longitudinally displaceable in the longitudinal direction of the longer leg, ie in the direction of arrow E. The holding element 28 can be fixed in its position by means of a locking screw designated 29. On the shorter leg of the holding element 25 is also an L-shaped support 30 is held, which has at its free end a downwardly projecting stop 31 which is integrally formed with the support 30. The stop 31 ends at a distance from the conveying strand 3a of the rear belt conveyor 3 and defines a passage gap 32 therewith. The size of this passage gap 32 can be changed by moving the carrier 30 in the direction of the arrow F. A further locking screw 29 'is provided for locking the carrier 30. At the stop 31, a baffle plate 33 pointing towards the rear in the conveying direction A, B is attached.

Mit dem hinteren Bandförderer 3 wirken zwei frei drehbar gelagerte Förderrollen 34 und 35 (Fig. 2) zusammen, von denen jede in einem Doppelhebel 36 bzw. 37 gelagert ist. Jeder Doppelhebel 36, 37 ist mit einer seitlich wegragenden Abstützung 38, 39 versehen, auf der sich eine Verstellschraube 40 bzw. 41 abstützt. Diese Verstellschrauben 40, 41 durchsetzen den Querträger 27 und dienen dazu, die Schwenklage der Hebel 18, 19 bzw. der Doppelhebel 36, 37 einstellen zu können. Anders ausgedrückt kann mittels der Verstellschrauben 40, 41 die Neigung der Hebel 18, 19 in bezug auf die Doppelhebel 36, 37 verstellt werden.The rear belt conveyor 3 interacts with two freely rotatable conveyor rollers 34 and 35 (FIG. 2), each of which is mounted in a double lever 36 and 37, respectively. Each double lever 36, 37 is provided with a laterally projecting support 38, 39 on which an adjusting screw 40 and 41 is supported. These adjusting screws 40, 41 pass through the cross member 27 and serve to be able to adjust the pivot position of the levers 18, 19 or the double levers 36, 37. In other words, the inclination of the levers 18, 19 with respect to the double levers 36, 37 can be adjusted by means of the adjusting screws 40, 41.

An einem, Teil des Rahmens bildenden, Querträger 42 ist ein Druckmechanismus 43 befestigt, der aus einer Druckfeder 44 und einer Einstellschraube 45 gebildet wird. Die sich auf dem Querträger 27 abstützende Druckfeder 44 übt auf die Hebel 18,19 und über die Verstellschrauben 40, 41 auch auf die Doppelhebel 36, 37 einen Druck aus, was bewirkt, dass die Förderrollen 34, 35 gegen den hinteren Bandförderer 3 bzw. die geförderte Schuppenformation S' gedrückt werden, und die Mitnahmeräder 14, 15 in ihrer durch die Verstellschrauben 40, 41 festgelegten Höhenlage bezüglich der Förderrollen 34, 35 gehalten werden. Der von der Druckfeder 44 ausgeübte Druck kann mittels der Einstellschraube 45 verändert werden.A pressure mechanism 43, which is formed from a compression spring 44 and an adjusting screw 45, is fastened to a cross member 42 forming part of the frame. The compression spring 44 supported on the cross member 27 exerts pressure on the levers 18, 19 and, via the adjusting screws 40, 41, also on the double levers 36, 37, which causes the conveyor rollers 34, 35 against the rear belt conveyor 3 or the conveyed scale formation S 'are pressed, and the driving wheels 14, 15 are held in their height position, determined by the adjusting screws 40, 41, with respect to the conveyor rollers 34, 35. The pressure exerted by the compression spring 44 can be changed by means of the adjusting screw 45.

Die Wirkungsweise der vorstehend beschriebenen Vorrichtung ist wie folgt:

  • Durch den vorderen Bandförderer 2 werden die mit 46 bezeichneten Druckprodukte in Schuppenformation S in Förderrichtung A gegen die Anschlaganordnung 12 gefördert. Wie aus den Fig. I und 3 hervorgeht, liegt dabei jedes Druckprodukt 46 auf dem vorauslaufenden Druckprodukt auf. Dies bedeutet, dass die vorlaufenden Kanten 46a der Druckprodukte 46 in der zugeführten Schuppenformation S oben liegen. Der Schuppenabstand, d.h. der Abstand ai, a2 zwischen den vorlaufenden Kanten 46a aufeinanderfolgender Druckprodukte 46, ist in der ankommenden Schuppenformation S ungleichmässig. So ist der Schuppenabstand ai grösser als der Schuppenabstand a2.
The operation of the device described above is as follows:
  • By means of the front belt conveyor 2, the printed products denoted by 46 are conveyed in scale formation S in the conveying direction A against the stop arrangement 12. As can be seen from FIGS. I and 3, each printed product 46 rests on the preceding printed product. This means that the leading edges 46a of the printed products 46 lie on top in the supplied scale formation S. The scale spacing, ie the distance ai, a 2 between the leading edges 46a of successive printed products 46, is uneven in the incoming scale formation S. The scale distance ai is greater than the scale distance a 2 .

Die in Richtung des Pfeiles A auf den Anschlag 31 zulaufenden Druckprodukte 46, welche durch das Leitblech 33 an einem Hochbiegen gehindert werden, kommen mit ihrer vorlaufenden Kante 46a, die beim gezeigten Ausführungsbeispiel die Falzkante ist, am Anschlag 31 zum Anstehen. Die Vorwärtsbewegung des jeweils am Anschlag 31 anstehenden Druckproduktes 46' wird somit gestoppt. Die, wie beschrieben, mit der Umfangsgeschwindigkeit v2 umlaufenden Mitnahmeräder 14, 15 kommen nun periodisch mit ihren Mitnahmenocken 16 auf den vorauslaufenden Bereich 47 der jeweils am Anschlag 31 anstehenden Druckprodukte 46 zur Einwirkung, wie das in den Fig. I und 3 an Hand des mit 46' bezeichneten Druckproduktes dargestellt ist. Der Mitnahmenocken 16 lenkt den vorlaufenden Bereich 47 des Druckproduktes 46' nach unten aus und drückt ihn gegen den angetriebenen Bandförderer 3 bzw. das durch diesen mitgenommene vorauslaufende Druckprodukt. Dieses Druckprodukt 46' wird somit durch den Mitnahmenocken 16 und den Bandförderer 3 mitgenommen, durch den Durchtrittsspalt 32 hindurchgezogen und in den Förderspalt W zwischen den Förderrollen 34, 35 und dem förderwirksamen Trum 3a des hinteren Bandförderers 3 gebracht. Hier wird das Druckprodukt 46 zur Weiterförderung vom Förderband 3 übernommen, und die Mitnahmenocken 16 lösen sich vom Druckprodukt 46'. Das Biegen des vorlaufenden Bereiches 47 des Druckproduktes 46' nach unten und das damit verbundene Aufwölben dieses Druckproduktes 46' hat zur Folge, dass das nachfolgende Produkt 46 angehoben wird. Damit wird erreicht, dass dieses nachfolgende Produkt sicher am Anschlag 31 anstösst. Die Höhe des Durchtrittsspaltes 32 kann auf die Dicke der Produkte 46 abgestimmt werden, damit nicht zwei Druckprodukte miteinander durch diesen Durchtrittsspalt 32 hindurchgezogen werden können.The printed products 46 tapering towards the stop 31 in the direction of arrow A, which are prevented from bending up by the guide plate 33, come to rest against the stop 31 with their leading edge 46a, which is the folded edge in the exemplary embodiment shown. The forward movement of the printed product 46 'in each case at the stop 31 is thus stopped. The driving wheels 14, 15 rotating with the peripheral speed v 2 , as described, now come periodically with their driving cams 16 onto the leading area 47 of the printing products 46 pending at the stop 31, as shown in FIGS is shown with 46 'printed product. The driving cam 16 deflects the leading region 47 of the printed product 46 'downward and presses it against the driven belt conveyor 3 or the leading printed product carried by it. This printed product 46 'is thus taken along by the driving cams 16 and the belt conveyor 3, pulled through the passage gap 32 and brought into the conveyor gap W between the conveyor rollers 34, 35 and the conveying section 3a of the rear belt conveyor 3. Here, the printed product 46 is taken over by the conveyor belt 3 for further conveyance, and the driving cams 16 detach from the printed product 46 '. The bending of the leading area 47 of the printed product 46 'downward and the associated bulging of this printed product 46' has the consequence that the subsequent product 46 is raised. This ensures that this subsequent product hits the stop 31 securely. The height of the passage gap 32 can be matched to the thickness of the products 46 so that two printed products cannot be pulled together through this passage gap 32.

Wie bereits erwähnt, ist dem hintem Bandförderer 3 eine förderunwirksame Strecke 10 vorgeschaltet. Das Vorschieben der Druckprodukte 46 zum Anschlag 31 erfolgt somit in erster Linie durch das jeweils vorauslaufende Druckprodukt 46', das wie beschrieben durch Mitnahmenocken 16 zum Förderspalt W transportiert wird. Da das jeweils nachfolgende Druckprodukt 46 nicht vorgeschoben wird, währenddem das vorauslaufende Druckprodukt 46' am Anschlag 31 ansteht, bleibt der Schuppenabstand im wesentlichen unverändert. Würde namlich das nachfolgende Druckprodukt vorgeschoben, während das vorauslaufende Druckprodukt durch den Anschlag 31 an einer Weiterbewegung gehindert wird, so würde der Schuppenabstand verkleinert. Das Vorsehen der förderunwirksamen Strecke 10 hat den weiteren Vorteil, dass auf den nachlaufenden Bereich des am Anschlag 31 anstehenden Druckproduktes 46' keine Förderwirkung ausgeübt wird, welche ein unerwünschtes Aufwölben dieses Druckproduktes 46' zur Folge hätte.As already mentioned, the rear belt conveyor 3 is preceded by an ineffective section 10. The pushing of the printed products 46 to the stop 31 thus takes place primarily by the respective leading printed product 46 'which, as described, is transported to the conveyor gap W by driving cams 16. Since the respective subsequent printed product 46 is not advanced while the leading printed product 46 'is in contact with the stop 31, the scale distance remains essentially unchanged. If, in particular, the subsequent printed product was advanced while the preceding printed product was prevented from moving further by the stop 31, the scale spacing would be reduced. The provision of the ineffective section 10 has the further advantage that no conveying action is exerted on the trailing area of the printed product 46 'at the stop 31, which would result in an undesired bulging of this printed product 46'.

Da, wie bereits erwähnt, die durch die Mitnahmenocken 16 bewirkte Weiterbewegung der am Anschlag 31 anstehenden Druckprodukte 46 in zeitlich genau festgelegten Abständen erfolgt, ist der Schuppenabstand ao innerhalb der durch den hinteren Bandförderer 3 weggeführten Schuppenformation S' praktisch immer gleich. Unterschiede im Schuppenabstand a1, a2 im ankommenden Schuppenstrom S werden somit auf einfache Weise auch dann zuverlässig ausgeglichen, wenn die Druckprodukte 46 mit verhältnismässig hoher Geschwindigkeit v1, vo gefördert werden.Since, as already mentioned, the further movement of the printed products 46 at the stop 31, which is caused by the driving cams 16, takes place at precisely fixed intervals, the scale distance ao within the scale formation S 'carried away by the rear belt conveyor 3 is practically always the same. Differences in the scale spacing a 1 , a 2 in the incoming scale stream S are thus reliably compensated for in a simple manner even when the printed products 46 are conveyed at a relatively high speed v 1 , v o .

In Fig. 4 ist in einer Darstellung, die der Darstellung in Fig. 3 entspricht, eine zweite Ausführungsform einer Ver gleichmässigungsvorrichtung dargestellt. Dabei sind sich entsprechende Bauteile in den Fig. I - 3 und 4 mit denselben Bezugsziffern bezeichnet.In Fig. 4, a representation that corresponds to the representation in Fig. 3, a second embodiment of a Ver uniforming device is shown. Corresponding components in FIGS. 1-3 and 4 are designated by the same reference numerals.

Im Unterschied zur Ausführungsform gemäss den Fig. I - 3 ist bei der Ausführungsform gemäss Fig. 4 die Mitnehmeranordnung 13 unterhalb des Förderweges der Druckprodukte 46 angeordnet. Diese Druckprodukte 46 werden dafür im Gegensatz zur ersten Ausführungsform in einer Schuppenformation S zugeführt, in der jedes Druckprodukt 46 auf dem nachfolgenden Druckprodukt aufliegt. Dies bedeutet, dass in dieser Schuppenformation S die vorlaufenden Kanten 46a der Druckprodukte 46 unten liegen.In contrast to the embodiment according to FIGS. 1-3, in the embodiment according to FIG. 4 the driver arrangement 13 is arranged below the conveying path of the printed products 46. In contrast to the first embodiment, these printed products 46 are fed in a scale formation S in which each printed product 46 rests on the subsequent printed product. This means that in this scale formation S the leading edges 46a of the printed products 46 are at the bottom.

Wie aus Fig. 4 hervorgeht, ist in der förderunwirksamen Strecke 10 zwischen den beiden Bandförderern 2, 3 ein Stützblech 48 angeordnet, auf dem die Druckprodukte 46 mit ihrem vorlaufenden Bereich 47 zur Auflage kommen. Die Mitnehmeranordnung 13 weist ebenfalls zwei Mitnahmeräder auf, von denen nur das Mitnahmerad 49 sichtbar ist. Die Mitnahmeräder 49 sind ebenfalls mit abstehenden Mitnahmenocken 50 versehen, die in Umfangsrichtung gleichmässig verteilt angeordnet sind. Die Mitnahmeräder 49 werden in Richtung des Pfeiles G mit der Umfangsgeschwindigkeit v2 umlaufend angetrieben.As can be seen from FIG. 4, a support plate 48 is arranged in the ineffective section 10 between the two belt conveyors 2, 3, on which the printed products 46 come to rest with their leading area 47. The driver arrangement 13 also has two driver wheels, of which only the driver wheel 49 is visible. The driving wheels 49 are also provided with projecting driving cams 50 which are arranged evenly distributed in the circumferential direction. The driving wheels 49 are driven in the direction of arrow G at circumferential speed v 2 .

Die Anschlaganordnung 12 weist einen Anschlag 51 auf, der durch einen hochgebogenen Teil des Stützbleches 48 gebildet wird. Dieser Anschlag 51 geht in eine Führungsrampe 52 über.The stop arrangement 12 has a stop 51, which is formed by a bent-up part of the support plate 48. This stop 51 changes into a guide ramp 52.

Oberhalb des hinteren Bandförders 3 sind zwei Förderrollen angeordnet, von denen nur die Förderrolle 53 sichtbar ist. Jede Förderrolle 53 ist an einem schwenkbar gelagerten Hebel 54 gelagert. Die Förderrollen 53 werden in Richtung des Pfeiles H umlaufend angetrieben. Dies erfolgt über einen Antriebsriemen 55, der über eine Führungsrolle 56 geführt ist und in Richtung des Pfeiles I umläuft. Der zwischen der Führungsrolle 56 und der Förderrolle 53 liegende Abschnitt 55a des Antriebriemens 55 dient zudem als oberes Begrenzungselement.Above the rear belt conveyor 3, two conveyor rollers are arranged, of which only the conveyor roller 53 is visible. Each conveyor roller 53 is mounted on a pivotably mounted lever 54. The conveyor rollers 53 are driven in a rotating manner in the direction of the arrow H. This is done via a drive belt 55 which is guided over a guide roller 56 and rotates in the direction of arrow I. The section 55a of the drive belt 55 lying between the guide roller 56 and the conveyor roller 53 also serves as an upper limiting element.

Das Ausgleichen des Schuppenabstandes a1, a2 im ankommenden Schuppenstrom S erfolgt grundsätzlich auf die an Hand der Fig. I - 3. beschriebene Weise.The balancing of the scale spacing a 1 , a 2 in the incoming scale stream S is basically carried out on the basis of FIGS. 1-3 . described way.

Die in Richtung des Pfeiles A geförderten Druckprodukte 46 stossen mit ihrer vorlaufenden Kante 46a am Anschlag 51 an, wie das an Hand des mit 46' bezeichneten Produktes dargestellt ist. Der vorlaufende Bereich 47 des am Anschlag 51 anstehenden Produktes 46' wird nun durch einen Mitnahmenocken 50 erfasst, über den Anschlag 51 hinausgehoben und gegen den Abschnitt 55a des Antriebsriemens 55 bzw. das vorauslaufende Druckprodukt gedrückt, das durch die Förderrollen 53 und den Bandförderer 3 vorgeschoben wird. Zudem wird das Produkt 46' durch den Mitnahmenocken 50 und den Abschnitt 55a des Riemens 55 bzw. das vorauslaufende Druckprodukt in den Förderspalt W zwischen dem förderwirksamen Trum 3a des Förderers 3 und den Förderrollen 53 gezogen. Von diesem Zeitpunkt an übernehmen die Förderrollen 53 und der Bandförderer 3 den Weitertransport des Druckproduktes 46'. Auch bei dieser Ausführungsform ist der mit ao bezeichnete Schuppenabstand im durch den hinteren Bandförderer 3 weggeführten Schuppenstrom S' im wesentlichen immer gleich.The printed products 46 conveyed in the direction of arrow A abut with their leading edge 46a on the stop 51, as is illustrated by the product designated by 46 '. The leading area 47 of the product 46 'at the stop 51 is now captured by a driving cam 50, raised above the stop 51 and pressed against the section 55a of the drive belt 55 or the leading printed product which is advanced by the conveyor rollers 53 and the belt conveyor 3 becomes. In addition, the product 46 'is drawn through the driving cam 50 and the section 55a of the belt 55 or the leading printed product into the conveying gap W between the conveying strand 3a of the conveyer 3 and the conveying rollers 53. From this point on, the conveyor rollers 53 and the belt conveyor 3 take over the further transport of the printed product 46 '. In this embodiment too, the scale spacing denoted by ao in the scale stream S 'carried away by the rear belt conveyor 3 is essentially always the same.

Bei beiden gezeigten Ausführungsformen wird das am Anschlag 31,51 anstehende Druckprodukt 46' nach der Auslenkung durch einen Mitnahmenocken 16, 50 durch letzteren gegen den angetriebenen Bandförderer 3 bzw. den Abschnitt 55a des ebenfalls angetriebenen Antriebsriemens 55 bzw. das vorauslaufende Druckprodukt gedrückt, welches bereits durch den Bandförderer 3 und die Förderrollen 34, 35 bzw. 53 erfasst worden ist. Somit wird das am Anschlag 31, 51 zum Stillstand gekommene Druckprodukt 46' unmittelbar nach der Auslenkung klemmend festgehalten und mit der Fördergeschwindigkeit vo des hintern Bandförderers 3 vorwärtsbewegt. Damit wird sichergestellt, dass dieses Druckprodukt 46' seine Lage gegenüber dem vorauslaufenden Druckprodukt nicht verändern kann.In both embodiments shown, the printed product 46 'present at the stop 31, 51 is pressed after the deflection by a driving cam 16, 50 by the latter against the driven belt conveyor 3 or the section 55a of the drive belt 55, which is also driven, or the leading printed product, which already has been detected by the belt conveyor 3 and the conveyor rollers 34, 35 and 53, respectively. The printed product 46 ′ which has come to a standstill at the stop 31, 51 is thus held in a clamped manner immediately after the deflection and is moved forward at the conveying speed vo of the rear belt conveyor 3. This ensures that this printed product 46 'cannot change its position in relation to the preceding printed product.

Es versteht sich, dass die gezeigten Vergleichmässigungsvorrichtungen in verschiedenen Teilen anders als wie beschrieben ausgebildet sein können. Von den verschiedenen möglichen Varianten werden im folgenden nur einige wenige kurz erläutert.It is understood that the equalization devices shown can be designed differently in different parts than described. Only a few of the different possible variants are briefly explained below.

Statt, wie gezeigt, zwei Mitnahmeräder und einen Anschlag vorzusehen, der zwischen den Mitnahmerädern angeordnet ist, ist es auch möglich, zwei Anschläge und ein zwischen diesen angeordnetes Mitnahmerad vorzusehen. Anstelle von vier Mitnahmenocken kann eine grössere oder auch kleinere Anzahl von Mitnahmenocken vorgesehen werden.Instead of providing two drive wheels and a stop, which is arranged between the drive wheels, as shown, it is also possible to provide two stops and a drive wheel arranged between them. Instead of four driving cams, a larger or smaller number of driving cams can be provided.
