Die Umlenkwalze 37 ist ebenfalls frei drehbar am Tragbolzen 46 gelagert. Das bereits erwähnte, dem angetriebenen Förderrad 21 zugeordnete und den Führungsspalt 33 begrenzende Trum 31 des Anpressorgans 30 erstreckt sich zwischen den Umlenkwalzen 37 und 36. Durch Verstellung bzw. Verschwenkung des im wesentlichen tangential zum Förderrad 21 angeordneten Halters 43 um die Achse 41 kann der vom aktiven Trum 31 und dem Förderrad 21 gebildete Förderspalt 33, insbesondere dessen Einlauf, je nach Dicke der zu verarbeitenden Druckereiprodukte 1 eingestellt und mittels der Klemmschraube 45 fixiert werden. The conveyor 20 also has an associated with the feed wheel 21 Pressing member 30 on that as a belt conveyor is formed, of which a strand 31 forms part of the circumferential surface 28 of the feed wheel 21 is assigned and with this together a guide gap 33 for the printed products 1 forms. The pressing member 30 is as a belt conveyor trained and arranged with several in parallel Pressure belt 34 equipped that closed in itself are guided around three guide rollers 35, 36, 37. Two of the deflecting rollers 35, 36 are fixed to one in each arranged in the upper region of the device frame 8, horizontal axis 41, 42 freely rotatable; the axes 41, 42 are parallel to one another and to the shaft 22 arranged. On the axis 41 is one with two jaws 44 provided holder 43 fastened by means of a clamping screw 45, the down near the intermediate stack 5 protrudes and with a support pin 46 for the third, lower Deflection roller 37 is provided. The deflection roller 37 is also freely rotatably supported on the support pin 46. That already mentioned, assigned to the driven feed wheel 21 and the guide gap 33 delimiting strand 31 of the pressing member 30 extends between the deflection rollers 37 and 36. By adjusting or pivoting the essentially arranged tangentially to the feed wheel 21 holder 43 around the Axis 41 can be that of the active strand 31 and the feed wheel 21 Conveying gap 33 formed, in particular its inlet, each adjusted according to the thickness of the printed products 1 to be processed and be fixed by means of the clamping screw 45.

Im Vorrichtungsgestell 8 ist parallel zur Welle 22 und zu den Achsen 41, 42 eine Traverse 47 eingebaut, auf welcher zu beiden Seiten des Förderrades 21 je ein Stütz- und Führungsblech 48, 49 verstellbar (über Schrauben 50 nach Fig. 2) angeordnet ist. Mit Hilfe der Stütz- und Führungsbleche 48, 49 werden die Druckereiprodukte 1 über ihre Breite geführt bzw. ein seitliches Abkippen derselben wird verhindert.In the device frame 8 is parallel to the shaft 22 and the axes 41, 42 a crossbar 47 installed, on which a support and guide plate on each side of the feed wheel 21 48, 49 adjustable (using screws 50 according to Fig. 2) is arranged. With the help of the support and guide plates 48, 49, the printed products 1 are guided over their width or a lateral tilting of the same is prevented.

Nachfolgend wird nun die Wirkungsweise der beschriebenen Vorrichtung erläutert, sofern sich diese nicht bereits aus den vorstehenden Ausführungen ergibt.The mode of operation of those described will now be described Device explained if this is not already out results from the above statements.

Die in der ersten Schuppenformation S1 durch die erste Fördereinrichtung 3 zugeführten Druckereiprodukte 1 werden mit der Falzkante 1a unten in den Zwischenstapel 5 eingeschoben. Das jeweils oberste Druckereiprodukt 1 des Zwischenstapels 5 wird mittels der mit der Unterdruckquelle verbundenen Saugköpfe 11 des Anhebeorgans 10 im Bereich der Falzkante 1a erfasst und in eine sich momentan oberhalb der Falzkante la befindende Ausnehmung 26 des in Drehrichtung D angetriebenen Förderrades 21 eingeführt. Sobald das angehobene Druckereiprodukt 1 von der Seitenfläche 26a der betreffenden Ausnehmung 26 des Förderrades 21 mitgenommen und zum Führungsspalt 33 gelenkt wird, kehrt das von der Unterdruckquelle abgeschaltete Anhebeorgan 10 - dem Druckereiprodukt 1 dabei aus dem Weg ausweichend - entlang der Umlaufbahn 14 in seine Ausgangsposition zurück, um das nächste Druckereiprodukt 1 zu erfassen und in die nächste Ausnehmung 26 einzuführen. Inzwischen wird das Druckereiprodukt 1 aus der Ausnehmung 26 und in den Führungsspalt 33 zwischen die Umfangsfläche 28 des dieser Ausnehmung 26 in Drehrichtung D vorstehenden Radsegmentes 27 und das vorstehende Druckereiprodukt 1 gedrängt und sein Transport beginnt. So wird jedes Druckereiprodukt 1 in eine der Ausnehmungen 26 nacheinanderfolgend eingeführt, wobei der Antrieb des Anhebeorgans 10 synchron zum Förderradantrieb erfolgt. In dieser Weise wird die neue Schuppenformation S2 von Druckereiprodukten 1 gebildet, in der wiederum jedes Druckereiprodukt 1 auf dem nachfolgenden aufliegt und die vorlaufende Falzkante la jeweils unten liegt. Dabei bestimmt das Förderrad 21 des Wegförderers 20 mit seiner Umfangsgeschwindigkeit nicht nur die Fördergeschwindigkeit der wegzufördernden Druckereiprodukte 1; auch der Schuppenabstand wird durch das Förderrad 21 definiert und durch den Abstand der Radsegmente 27 (am Umfang des Förderrades 21 gemessen) bestimmt. Die Form der Ausnehmungen 26 ermöglicht, dass die Druckereiprodukte 1 ohne Knicken oder andere Deformation in den Führungsspalt 33 geleitet werden können. Während in der ersten Schuppenformation S1 Unregelmässigkeiten im Schuppenabstand auftreten und Druckereiprodukte 1 fehlen konnten, wird durch die erfindungsgemässe Vorrichtung eine neue, genau definierte Schuppenformation S2 gebildet, die keine Unregelmässigkeiten aufweist.Those in the first scale formation S1 through the first Conveyor 3 supplied printing products 1 with the folded edge 1a inserted into the intermediate stack 5 below. The top printing product 1 of each Intermediate stack 5 is by means of the vacuum source connected suction heads 11 of the lifting member 10 in the area the folded edge 1a is gripped and currently in one Recess 26 located above the folded edge la of the in Direction of rotation D driven feed wheel 21 introduced. As soon as the raised printed product 1 from the side surface 26a of the relevant recess 26 of the feed wheel 21 is carried along and directed to the guide gap 33, returns the lifting device switched off by the vacuum source 10 - evading the printed product 1 out of the way - Along the orbit 14 in its starting position back to capture the next printed product 1 and insert into the next recess 26. In the meantime the printed product 1 from the recess 26 and in the guide gap 33 between the peripheral surface 28 of the this recess 26 in the direction of rotation D protruding wheel segment 27 and the above printed product 1 pushed and its transportation begins. This is how every printed product becomes 1 in one of the recesses 26 in succession introduced, the drive of the lifting member 10th done synchronously to the conveyor wheel drive. That way will be the new scale formation S2 of printed products 1 formed, in turn on each printed product 1 the following lies and the leading fold edge la is below. The feed wheel 21 determines of the conveyor 20 with its peripheral speed not just the conveying speed of the conveyed away Printed products 1; the scale distance is also determined by the feed wheel 21 is defined and by the distance between the wheel segments 27 (measured on the circumference of the feed wheel 21). The shape of the recesses 26 enables the Printed products 1 without buckling or other deformation can be passed into the guide gap 33. While in the first scale formation S1 irregularities in the Scale spacing occurs and print products 1 are missing could, the device according to the invention new, precisely defined scale formation S2 formed, the has no irregularities.

Die den Wegförderer in Richtung B verlassenden Druckereiprodukte 1 werden in nicht dargestellter Weise erfasst und weggeführt, noch bevor die nachlaufende Kante 1b den Führungsspalt 33 verlässt. Der den Führungsspalt 33 verlassende Teil der Druckereiprodukte 1 wird durch die Stütz- und Führungsbleche 48, 49 untergriffen.The printed products leaving the conveyor in direction B. 1 are recorded in a manner not shown and led away even before the trailing edge 1b the guide gap 33 leaves. The one leaving the guide gap 33 Part of the printed products 1 is by the Support and guide plates 48, 49 gripped.

Wie in Fig.1 strichpunktiert angedeutet, könnte auch eine Schuppenformation S3, in welcher ebenfalls jedes Druckereiprodukt 1 auf dem nachfolgenden aufliegt, jedoch die vorlaufende, unten liegende Kante durch die offene Seitenkante 1b gebildet wird, erfindungsgemäss zu der Weiterverarbeitungsstelle gefördert werden. In diesem Falle müsste jedoch der Anschlag 4 derart nach links (in Fig. 1 betrachtet) versetzt werden, dass sich die mittels einer Fördervorrichtung 3' in Pfeilrichtung C zugeführten Druckereiprodukte 1 wiederum mit ihrer - diesmal nachlaufenden - Falzkante unterhalb vom Anhebeorgan 10 im Zwischenstapel 5 befinden würden. Das weitere Vorgehen bzw. Wegfördern der Druckereiprodukte 1 in der neuen Schuppenformation S2 zur Weiterverarbeitungsstelle würde gleich erfolgen, wie bereits beschrieben.As indicated by dash-dotted lines in Fig. 1, one could also Scale formation S3, in which each printed product also 1 rests on the following, but the leading, bottom edge through the open side edge 1b is formed, according to the invention to the further processing point be promoted. In this case however, the stop 4 to the left (viewed in FIG. 1) be transferred so that the by means of a Conveyor 3 'fed in the direction of arrow C. Printed products 1 again with their - this time trailing - Folding edge below the lifting element 10 in the intermediate stack 5 would be. The further procedure or Removing the printed products 1 in the new scale formation S2 to the finishing station would be the same take place as already described.
