Abstract

The transport clamps (16) driven in the conveying direction (F) hold the printed products (26) in the region of their fold (28). Underneath the conveying means (10) there is a supporting element (38) which supports the printed products in their edge region (44) and with the leading edge (34). Arranged on rotating supporting arms (70) are opening elements (22) resembling suction heads, which, as a result of the inward pivoting of the supporting arms (70), engage in each case between two printed products (26) and come to bear from above on the edge region (44) of the printed product to be opened. Mounted on the hollow shaft (48) is a suction roller, of which a suction head (50) comes to bear in each case on the edge region (44) from below. The opening element (72) and the suction roller (46) retain respectively the first and second product part (30, 32) of the printed product for the purpose of opening the printed product (26) and lift these off from one another, after which a keeping-open element (102) moves from below between the product parts (30, 32) in order to keep the printed product (26) open during further transport. <IMAGE>

It is an object of the present invention to provide an apparatus for opening and transporting folded To create printed products that are large Processing speed a safe and the printing products gentle opening allowed and insertion of a hold-open element between the lifted off Allows product parts at any point.  

Diese Aufgabe wird durch eine Vorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist. This object is achieved by a device that Features of claim 1.

Erfindungsgemäss werden die Druckereiprodukte mittels Transportklammern bei ihrem Falz gehalten, im wesentlichen in vertikaler Hängelage transportiert und mit ihrem in Förderrichtung nach vorne gebogenen, dem Falz gegenüberliegenden Endbereich abgestützt, etwa in Förderrichtung geschoben. Dies vermittelt der dem Falz gegenüberliegenden offenen Kante der Druckereiprodukte eine definierte Lage, stabilisiert durch das Biegen die Druckereiprodukte und hält diese in sicherem Abstand zueinander, so dass ein Oeffnungselement von oberhalb dem die Druckereiprodukte stützenden Stützelement zwischen Druckereiprodukte eingefahren werden kann. Dadurch ist auch die Zugänglichkeit zum abgestützten Randbereich von oben sichergestellt, so dass sich das Oeffnungselement im Randbereich an den obenliegenden Produktteil flach anlegen kann, um diesen festzuhalten. Da das Oeffnungselement von oberhalb des Stützelements zwischen die Druckereiprodukte eingreift und sich an diese anlegt und ein Halteelement sich von unten an das Druckereiprodukt anlegt, ist das Festhalten der Produkteteile während des gesamten Oeffnungsvorgangs ermöglicht, was ein sicheres Oeffnen bei hoher Verarbeitungsgeschwindigkeit gewährleistet. Ueberdies befinden sich keine Teile des Oeffnungsaggregates im Bereich der dem Falz gegenüberliegenden offenen Kante. Ein Offenhalteelement kann somit an beliebiger Stelle zwischen die voneinander abgehobenen Produkteteile eingreifen. Ueberdies ist ein grosser Oeffnungshub erzielbar, da die Umlaufbann des Halteelements und Bewegungsbahn des Oeffnungselements voneinander unabhängige Form aufweisen können. According to the invention, the printed products are Transport clips held at their fold, essentially transported in a vertical hanging position and with its in Direction of conveyance bent forward, opposite the fold End area supported, for example in the direction of conveyance pushed. This conveys the opposite of the fold open edge of the printed products a defined position, stabilizes the printed products and by bending keeps them at a safe distance from each other, so that a Opening element from above which the printed products supporting support element retracted between printed products can be. This also makes it accessible to the supported edge area from above, so that the opening element in the edge area on the top Can lay the product part flat to hold it. Since the opening element from above the support element intervenes between the printed products and itself attaches to this and a holding element from below to the Creating a printed product is to hold the product parts enabled during the entire opening process, what a safe opening at high processing speed guaranteed. Moreover, there are no parts of the opening unit in the area of the opposite of the fold open edge. A hold-open element can thus anywhere between the different ones Intervene in product parts. In addition, there is a large opening stroke achievable because the circulation spell of the holding element and movement path of the opening element independent of each other Can have shape.

Eine besonders bevorzugte Ausbildungsform der erfindungsgemässen Vorrichtung ist im Anspruch 2 angegeben. Da das Oeffnungselement von der Seite her zwischen die Druckereiprodukte eingreift, kann die Vorrichtung einfach und raumsparend ausgebildet sein. A particularly preferred embodiment of the invention Device is specified in claim 2. Since that   Opening element from the side between the printed products engages, the device can be simple and be designed to save space.

Bei einer weiteren ebenfalls besonders bevorzugten Ausbildungsform gemäss Anspruch 4 wird der entsprechende Produkteteil um eine Walze in Richtung gegen unten und gegebenenfalls gegen hinten gebogen. Dadurch wird das dem Falz gegenüberliegende Ende des entsprechenden Produkteteils in Richtung gegen unten dem Offenhalteelement entgegengefördert, wodurch gleichzeitig das Druckereiprodukt unter Verkleinerung der durch das Stützelement hervorgerufenen Biegung gestreckt wird. Dies führt zu erhöhter Stabilität im Druckereiprodukt und einem schnellen sicheren Kämmen des Offenhalteelementes und des Produkteteiles. In another particularly preferred form of training According to claim 4, the corresponding part of the product around a roller towards the bottom and if necessary bent towards the back. This will make the fold opposite end of the corresponding product part in Directed towards the bottom of the hold-open element, thereby reducing the size of the printed product the bend caused by the support element is stretched. This leads to increased stability in the Printed product and a quick safe combing of the Keep open element and the product part.

in the same representation as in Fig. 5, a further embodiment of the device according to the invention.

In der Fig. 1 ist eine Fördereinrichtung 10 bekannter Art gezeigt, die im Abstand an einer in Förderrichtung F und mit Fördergeschwindigkeit vf umlaufend angetriebenen, in einem Kanal 12 geführten Förderkette 14 angeordnete, einzeln steuerbare Transportklammern 16 aufweist. Die Schwenklage der Transportklammern 16 um eine jeweils rechtwinklig zur Förderrichtung F verlaufende Achse ist mittels ortsfester Schwenkkulissen 18, die mit den Folgerollen 20,20' der Transportklammern 16 zusammenwirken, derart gesteuert, dass das Klammermaul 22 im gezeigten Abschnitt der Fördereinrichtung 10 im wesentlichen in vertikaler Richtung nach unten gerichtet ist. Es sei auch erwähnt, dass oberhalb ungefähr der Mitte einer angedeuteten Verarbeitungstrommel 24 ein Auslöseorgan angeordnet ist, um das Oeffnen des Greifmauls 22 zu steuern. Transportklammern 16 dieser Art sind beispielsweise aus der EP-A-0 557 680 und der entsprechenden US-Patentanmeldung Nr. 08/018 749 bekannt. 1 shows a conveyor device 10 of a known type, which has individually controllable transport clamps 16 which are arranged at a distance from a conveyor chain 14 which is driven in rotation in the conveying direction F and at conveyor speed v f and is guided in a channel 12. The swivel position of the transport clamps 16 about an axis running at right angles to the conveying direction F is controlled by means of fixed swivel links 18, which interact with the follow rollers 20, 20 'of the transport clamps 16, in such a way that the clamp mouth 22 in the section of the conveying device 10 shown is essentially vertical Is directed downwards. It should also be mentioned that a trigger element is arranged above approximately the center of an indicated processing drum 24 in order to control the opening of the gripping mouth 22. Transport clips 16 of this type are known, for example, from EP-A-0 557 680 and the corresponding US patent application No. 08/018 749.

Weiter ist das Klammermaul 22 der Transportklammern 16 rechtwinklig zur Förderrichtung F ausgerichtet und dazu bestimmt, jeweils ein gefaltetes Druckereiprodukt 26 in einem Bereich benachbart zum in etwa in horizontaler Richtung und etwa rechtwinklig zur Förderrichtung F verlaufenden Falz 28 hängend zu halten. Der Falz verbindet zwei Produkteteile 30,32, wobei in Förderrichtung F gesehen der erste Produkteteil 30 bezüglich dem zweiten Produkteteil 32 nachlaufend ist. Mit 34 ist die dem Falz 28 gegenüberliegende offene Kante, die sogenannte Blume, der Druckereiprodukte 26 bezeichnet. The clamp jaw 22 of the transport clamps 16 is also present aligned perpendicular to the conveying direction F and to it determined, each a folded printed product 26 in an area adjacent to approximately in the horizontal direction and approximately at right angles to the conveying direction F. Keep fold 28 hanging. The fold connects two Product parts 30,32, viewed in the conveying direction F of first product part 30 with respect to the second product part 32 is lagging. At 34 is the fold 28 opposite open edge, the so-called flower, of printed products Designated 26.  

Unterhalb des in etwa in horizontaler Richtung verlaufenden Abschnitts der Fördereinrichtung 10 ist ein Oeffnungsaggregat 36 angeordnet, das weiter unten genauer zu beschreiben ist. Dem Oeffnungsaggregat 36 ist ein ebenfalls unterhalb der Fördereinrichtung 10 angeordnetes Stützelement 38 unmittelbar vorgeschaltet, das endlose um Umlenkwalzen 40 geführte Stützbändchen 42 aufweist, deren oberer stützwirksamer Trum 42' in Förderrichtung F gesehen leicht ansteigend angeordnet und in Umlaufrichtung S mit einer Geschwindigkeit vs angetrieben ist, die grösser, vorzugsweise doppelt so gross ist, wie die Fördergeschwindigkeit Vf. Im Anfangsbereich des Stützelements 38 kommen die Druckereiprodukte 26 mit ihrer Kante 34 auf die Stützbändchen 42 zur Anlage und werden im Zuge des Weitertransports in Förderrichtung F nach vorne gebogen, so dass sie mit ihrem an die Kante 34 anschliessenden Endbereich 44 auf dem Stützbändchen 42 flach aufliegen. Die Stützbandchen 42 bilden somit eine Förderebene 38', die den Endbereich 44 der Druckereiprodukte 26 in Förderrichtung F schiebt. An opening unit 36, which is to be described in more detail below, is arranged below the section of the conveying device 10 which runs approximately in the horizontal direction. A support element 38, which is likewise arranged below the conveyor device 10, is connected directly upstream of the opening unit 36 and has endless support bands 42 guided around deflection rollers 40, the upper support-effective strand 42 'of which, viewed in the conveying direction F, is arranged to rise slightly and is driven at a speed v s in the circumferential direction S. , which is larger, preferably twice as large, as the conveying speed V f . In the initial area of the support element 38, the printed products 26 come to rest with the edge 34 on the support tape 42 and are bent forward in the course of further transport in the conveying direction F, so that they lie flat on the support tape 42 with their end area 44 adjoining the edge 34 . The support bands 42 thus form a conveying plane 38 ′ which pushes the end region 44 of the printed products 26 in the conveying direction F.

Anhand der Fig. 1, in Zusammenschau mit den Fig. 2 bis 4, wird nun das Oeffnungsaggregat 36 näher beschrieben. Dieses weist eine Saugwalze 46 auf, die auf derselben, horizontal und rechtwinklig zur Förderrichtung F angeordneten Hohlwelle 48 wie die Umlenkwalzen 40 für die Stützbändchen 42 am Ende des Stützelements 38 frei drehbar gelagert ist. Die Saugwalze 46 weist in Umfangsrichtung gleichmässig verteilt drei Saugköpfe 50 auf, deren Umlaufbahn die vom oberen Trum 42' der Stützbändchen 42 definierten Förderebene 38' im wesentlichen tangiert. An die Saugköpfe 50 schliessen Radialdurchlässe 52 durch die Saugwalze 46 an, die mit Oeffnungen in der Hohlwelle 48 zusammenwirken um die Saugköpfe 50 in Abhängigkeit von der Drehlage der Saugwalze 46 vorübergehend mit dem Innern der Hohlwelle 48 zu verbinden, die mit einer nicht gezeigten Unterdruckquelle verbunden ist. In die Hohlwelle 38 greift vom öffnungsaggregatseitigen Ende her ein rohrartiger Steuerzapfen 54 ein, dessen Drehlage bezüglich der Hohlwelle 48 verstellbar ist und einen Entlüftungskanal 56 aufweist, um sofort nach dem Trennen der Verbindung eines Radialdurchlasses 52 mit dem Innern der Hohlwelle 48 den Radialdurchlass 52 mit der Umgebung zu verbinden und den betreffenden Saugkopf 50 zu belüften. Wie dies insbesondere aus den Fig. 2 und 3 hervorgeht, ist die Saugwalze 46 über einen Zahnriementrieb 58 mit einer im Takt der Fördereinrichtung 10 angetriebenen Antriebswelle 60 derart verbunden, dass die Saugköpfe 50 in Drehrichtung U (vergleiche Fig. 5) einen Weg zurücklegen, der in etwa 75 % des Weges entspricht, den die Transportklammern 16 in derselben Zeit zurücklegen. 1, in conjunction with FIGS. 2 to 4, the opening unit 36 will now be described in more detail. This has a suction roll 46 on the same, horizontally and arranged at right angles to the conveying direction F. Hollow shaft 48 as the deflection rollers 40 for the support tapes 42 is freely rotatably supported at the end of the support element 38. The suction roller 46 has a uniform circumferential direction distributes three suction heads 50, the orbit of which from upper run 42 'of the support band 42 defined conveying plane 38 'essentially affected. To the suction heads 50 connect radial passages 52 through the suction roller 46, which interact with openings in the hollow shaft 48   the suction heads 50 depending on the rotational position of the Suction roller 46 temporarily with the interior of the hollow shaft 48 to connect with a vacuum source, not shown connected is. The hollow shaft 38 engages from the opening unit side In the end a tubular control pin 54, whose rotational position with respect to the hollow shaft 48 is adjustable and has a ventilation channel 56 in order immediately after disconnecting a radial diffuser 52 with the inside of the hollow shaft 48 the radial passage 52 to connect with the environment and the concerned To ventilate suction head 50. How this in particular from the 2 and 3 emerges, the suction roller 46 is one Toothed belt drive 58 with one in time with the conveyor 10 driven drive shaft 60 connected such that the suction heads 50 in the direction of rotation U (see FIG. 5) cover a distance approximately 75% of the way, the transport clips 16 at the same time return.

Wie dies insbesondere aus den Fig. 2 und 3 hervorgeht, ist das Oeffnungsaggregat 36 in Richtung der Achse der Hohlwelle 48 versetzt ausserhalb des durch die Stützbändchen 42 gebildeten Stützelements 38 angeordnet In der gezeigten Ausbildungsform befindet sich das Oeffnungsaggregat 36 in Förderrichtung F gesehen rechts bezüglich des äussersten diesseitigen Stützbändchens 42. As can be seen in particular from FIGS. 2 and 3 the opening unit 36 in the direction of the axis of the hollow shaft 48 offset outside of by the support band 42 formed support element 38 arranged in the shown Form of training is the opening unit 36 seen in conveying direction F on the right with respect to the outermost support band 42 on this side.

In Richtung der Hohlwelle 48 gesehen, weist das Oeffnungsaggregat 36 auf der bezüglich den Stützbändchen 42 abgewandten Seite der Saugwalze 46 ein scheibenartig ausgebildetes Tragelement 62 auf, das an einer am Gestell 63 befestigten Achse 64 frei drehbar gelagert ist. Die Achse 64 verläuft rechtwinklig zur Förderrichtung F und in horizontaler Richtung und ist bezüglich der Hohlwelle 48 in etwa vertikaler Richtung gegen unten versetzt angeordnet. Radial aussen sind am Tragelement 62 in Umfangsrichtung verteilt Lagerböcke 66 befestigt, an deren rechtwinklig zur Achse 64 und in tangentialer Richtung verlaufenden Lagerschäften 68 jeweils ein doppelhebelartiger Tragarm 70 schwenkbar gelagert ist. Dieser trägt einerends ein als Saugkopf ausgebildetes Oeffnungselement 72 und andernends eine mit Steuerkulissen 74 zusammenwirkende Steuerrolle 76. Der Tragarm 70 ist mittels der Steuerkulissen 74 aus einer in den Fig. 2 und 4 gezeigten Ruhelage 78 in eine in der Fig. 3 dargestellte Arbeitslage 78' und wieder zurück verschwenkbar. In Arbeitslage 78' verläuft der das Oeffnungselement 72 tragende Teil des Tragarms 70 in etwa parallel zur Achse 64 und steht vom Tragelement 62 in Richtung gegen die Saugwalze 46 vor, so dass sich in Arbeitslage 78' das Oeffnungselement 72 in jener Ebene bewegt, in welcher die Saugköpfe 50 der Saugwalze 46 umlaufen. In Ruhelage 78 verläuft der das Oeffnungselement 72 tragende Teil des Tragarms 70 bezüglich der Achse 64 und Hohlwelle 48 etwa in radialer Richtung mit bezüglich dem Lagerschaft 68 aussen liegendem Oeffnungselement 72. Zwischen dem Tragarm 70 und dem Tragelement 62 wirkt eine Feder 80 um den Tragarm 70 in Ruhelage 78 und Arbeitslage 78' gegen diese Lagen definierende Anschläge 82 zu drängen. Seen in the direction of the hollow shaft 48, the opening unit 36 on the side facing away from the support band 42 Side of the suction roller 46 is a disc-shaped Support element 62, which is attached to a frame 63 Axis 64 is freely rotatable. The axis 64   runs perpendicular to the conveying direction F and in a horizontal direction Direction and is approximately with respect to the hollow shaft 48 vertically offset towards the bottom. Radial are distributed on the outside of the support element 62 in the circumferential direction Bearing blocks 66 attached, at right angles to Axis 64 and tangential bearing shafts 68 each have a double lever-like support arm 70 is pivotally mounted. One enters this as Suction head formed opening element 72 and other a control roller cooperating with control links 74 76. The support arm 70 is made by means of the control link 74 a rest position 78 shown in FIGS. 2 and 4 in a in 3 working position 78 'and back again pivotable. In the working position 78 ', the opening element runs 72 supporting part of the support arm 70 approximately parallel to the axis 64 and is from the support member 62 in the direction against the suction roller 46, so that in the working position 78 'the opening element 72 moves in that plane in which revolve around the suction heads 50 of the suction roller 46. In The rest position 78 is that of the opening element 72 Part of the support arm 70 with respect to the axis 64 and hollow shaft 48 approximately in the radial direction with respect to the bearing shaft 68 outer opening element 72. Between the The support arm 70 and the support element 62 act around a spring 80 the support arm 70 in the rest position 78 and working position 78 'against to push these positions defining stops 82.

Das saugkopfartige Oeffnungselement 72 kommuniziert in Arbeitslage 78' über einen Kanal 84 im Tragarm 70 mit einem weiteren Kanal 84' im Lagerbock 66. Der weitere Kanal 84' ist über eine Rohrleitung 86 mit einem auf der Achse 64 angeordneten Ventilorgan 88 verbunden, das dazu bestimmt ist, die Rohrleitung 86 in Abhängigkeit von der Drehlage des Tragelements 62 mit einer nicht gezeigten Unterdruckquelle bzw. mit einem mit der Umgebung verbundenen Entlüftungsdurchlass 90 zu verbinden. Zu diesem Zweck weist die Achse 64 einen mit der Unterdruckquelle verbundenen Hohlraum 92 auf, in den eine radiale Oeffnung 94 mündet. Beim Drehen des Tragelements 62 in Drehrichtung V, die der Drehrichtung U der Saugwalze 46 gleichgerichtet ist kommt die Oeffnung 94 mit der Rohrleitung 86 vorübergehend in Verbindung, um im Oeffnungselement 72 Unterdruck zu erzeugen. In Drehrichtung V der Oeffnung 94 folgend kommt beim Weiterdrehen die Rohrleitung 86 mit dem Entlüftungsdurchlass 90 in Verbindung, um das Oeffnungselement 72 zu lüften. The suction head-like opening element 72 communicates in FIG Working position 78 'via a channel 84 in the support arm 70 with a further channel 84 'in the bearing block 66. The further channel 84 'is connected via a pipeline 86 with one on the Axle 64 arranged valve member 88 connected to this   is determined, the pipe 86 depending on the Rotational position of the support element 62 with a not shown Vacuum source or one connected to the environment To connect vent passage 90. To this end axis 64 has one connected to the vacuum source Cavity 92 into which a radial opening 94 flows. When rotating the support element 62 in the direction of rotation V, the direction of rotation U of the suction roller 46 rectified the opening 94 comes with the pipe 86 temporarily in connection to vacuum in the opening element 72 to create. In the direction of rotation V following the opening 94 When turning further, the pipe 86 comes with the ventilation passage 90 connected to the opening element 72 to air.

Das Tragelement 62 ist über einen weiteren Zahntrieb 96 mit der Antriebswelle 60 derart verbunden, dass die Oeffnungselemente 72 in Arbeitslage 78' der Tragarme 70 pro Takt einen Weg zurücklegen, der in etwa 80 % des Weges der Transportklammern 16 entspricht. Ueberdies sei erwähnt, dass der Radius jenes Abschnitts 97' der Bewegungsbahn 97 der Oeffnungselemente 72 bei in Arbeitslage 78' verschwenkten Tragarmen 70 grösser, vorzugsweise zwei bis zehnmal grösser ist als der Radius der Umlaufbahn 50' der Saugköpfe 50 der Saugwalze 46. Die Anzahl Oeffnungselemente 72 am Tragelement 62 ist derart festgelegt, dass sich bei jedem Arbeitstakt jeweils ein Oeffnungselement 72 an einer bestimmten Stelle befindet. Weiter sei erwähnt, dass der Abschnitt 97' der Bewegungsbahn 97 der Oeffnungselemente 72 in dem die Tragarme 70 in Arbeitslage 78' verschwenkt sind, die Förderebene 38' in etwa tangiert. The support element 62 is via a further pinion 96 connected to the drive shaft 60 such that the opening elements 72 in the working position 78 'of the support arms 70 pro Clock a distance that is about 80% of the way Transport clips 16 corresponds. Furthermore, it should be mentioned that the radius of that section 97 'of the trajectory 97 of the opening elements 72 when pivoted in the working position 78 ' Support arms 70 larger, preferably two to is ten times larger than the radius of the orbit 50 ' Suction heads 50 of the suction roller 46. The number of opening elements 72 on the support element 62 is fixed such that one opening element 72 at each work cycle a certain place. It should also be mentioned that the section 97 'of the movement path 97 of the opening elements 72 in which the support arms 70 pivoted in the working position 78 ' are, the conveyor plane 38 'roughly affected.  

Weiter sind in Richtung der Hohlwelle 48 gesehen, zwischen den Stützbändchen 42 und gegebenenfalls zwischen dem äussersten, dem Oeffnungsaggregat 36 zugewandten Stützbändchen 42 und der Saugwalze 46 endlose Nockenbänder 98 angeordnet, die um auf der Hohlwelle 48 frei drehbar gelagerte Umlenkräder 100 und um auf der Antriebswelle 60 drehfest sitzende Umlenkräder 100' geführt sind. Die Antriebswelle 60 verläuft parallel zur Hohlwelle 48, zwischen den Trumen der Stützbändchen 42 hindurch, so dass die Nocken 98' der Nockenbänder 98 zwischen der Antriebswelle 60 und Hohlwelle 48 von unten die Förderebene 38' durchstossen und mit ihrem freien Ende über diese vorstehen. Die Nockenbänder 98 sind mit einer Geschwindigkeit vn angetrieben, die grösser oder gleich der Geschwindigkeit vu der Saugköpfe 50 ist. Sie beträgt vorzugsweise etwa 80 % der Geschwindigkeit vf der Transportklammern 16. Entsprechend ist der Abstand zwischen den Nacken 98' in etwa 80 % so gross wie der Abstand der Transportklammern 16. Furthermore, in the direction of the hollow shaft 48, endless cam belts 98 are arranged between the support tapes 42 and optionally between the outermost support tapes 42 facing the opening unit 36 and the suction roller 46, which are provided around deflection wheels 100 which are freely rotatably mounted on the hollow shaft 48 and around the drive shaft 60 rotatably seated deflection wheels 100 'are guided. The drive shaft 60 runs parallel to the hollow shaft 48, between the strands of the support bands 42, so that the cams 98 'of the cam belts 98 between the drive shaft 60 and the hollow shaft 48 penetrate the conveying plane 38' from below and project with their free end above them. The cam belts 98 are driven at a speed v n which is greater than or equal to the speed v u of the suction heads 50. It is preferably approximately 80% of the speed v f of the transport clips 16. Accordingly, the distance between the neck 98 'is approximately 80% as large as the distance of the transport clips 16.

Weiter weist das Oeffnungsaggregat 36 ein schraubenlinienartig geformtes Offenhalteelement 102 auf, das um seine in etwa parallel zur Förderrichtung F verlaufende Schraubenachse 104 derart drehend angetrieben ist, dass der jeweils obenliegende Abschnitt 102' sich mit den Transportklammern 16 in Förderrichtung F mitbewegt. Diese Abschnitte 102' greifen jeweils zwischen die beim Oeffnen voneinander abgehobenen Produkteteile 30,32 ein, um diese beim Weitertransport offen zu halten. Wie Fig. 1 zeigt, ist die in Drehrichtung W umlaufend angetriebene Bearbeitungstrommel 24 mit dem Oeffnungsaggregat 36 und somit der Fördereinrichtung 10 derart synchronisiert, dass eine sattelförmige Auflage 106 jeweils von unten in eine Windung des Offenhalteelements 102 eingreift, sich mit dieser in Förderrichtung F bewegt und somit von unten in die voneinander abgehobenen und offengehaltenen Produkteteile 30,32 einsticht. Furthermore, the opening assembly 36 has a helical shape shaped hold-open element 102, which around its in screw axis running approximately parallel to the conveying direction F. 104 is rotatably driven so that each overhead section 102 'itself with the transport clips 16 moved in the conveying direction F. These sections 102 ' reach between those lifted from each other when opening Product parts 30,32 to this for further transport to keep open. As shown in Fig. 1, the in Direction of rotation W rotating driven drum 24 with the opening unit 36 and thus the conveyor 10 synchronized so that a saddle-shaped   Pad 106 each from below in one turn of the hold-open element 102 engages with this in the conveying direction F moves and thus from below into each other withdrawn and held open product parts 30,32.

Fig. 6 zeigt in gleicher Darstellung wie Fig. 5 eine weitere Ausbildungsform des Oeffnungsaggregates 36. Die Fördereinrichtung 10, das Stützelement 38 mit den Stützbändchen 42, die Nockenbänder 98 sowie das Offenhalteelement 102 sind in genau gleicher Art und Weise, wie weiter oben beschrieben, ausgeführt. Der Unterschied besteht darin, dass das nun in Drehrichtung V' angetriebene Tragelement 62 an einer der Achse 64 entsprechenden Achse gelagert ist, die etwa in vertikaler Richtung oberhalb der Hohlwelle 48 angeordnet ist. Die Tragarme 70 sind ebenfalls über Lagerböcke am Tragelement um Lagerschäfte 68 schwenkbar gelagert, die tangential zu ihrer Umlaufbahn um die Achse verlaufen. In Arbeitslage 78' der Tragarme 70 steht dessen das Oeffnungselement 72 tragender Teil vom Tragelement 62 in etwa rechtwinklig ab. Beim Zurückverschwenken in die Ruhelage 78 kommen die Oeffnungselemente 72 bezüglich der Lagerschäfte 68 radial innen zu liegen. FIG. 6 shows another in the same representation as FIG. 5 Form of training for the opening unit 36. The conveyor 10, the support element 38 with the support tape 42, the cam belts 98 and the hold-open element 102 are in exactly the same way as above described, executed. The difference is that the support element now driven in the direction of rotation V ' 62 mounted on an axis corresponding to the axis 64 which is approximately in the vertical direction above the hollow shaft 48 is arranged. The support arms 70 are also can be pivoted about bearing shafts 68 via bearing blocks on the support element stored that tangent to their orbit around the Axis run. In the working position 78 'of the support arms 70 is the part of the support element which carries the opening element 72 62 approximately at a right angle. When swiveling back the opening elements 72 come into the rest position 78 to lie radially inward with respect to the bearing shafts 68.

In den Fig. 5 und 6 ist mit 108 ein Rückführabschnitt der Bewegungsbahn 97 bezeichnet, in dem sich die Oeffnungselemente 72 in Ruhelage 78 befinden. Die Abschnitte der Bewegungsbahn 97', in der die Oeffnungselemente 72 von der Ruhelage 78 in die Arbeitslage 78' und zurück überführt werden, sind mit 108' bzw. 108'' bezeichnet. 5 and 6 with 108 is a return section of the Movement path 97 denotes, in which the opening elements 72 are in rest position 78. The sections of the Movement path 97 ', in which the opening elements 72 of the Rest position 78 in the working position 78 'and transferred back are designated by 108 'and 108' '.

Die Funktionsweise der beschriebenen Vorrichtungen wird nun insbesondere anhand der Fig. 5 und 6 näher beschrieben. In diesen sind die Klammermäuler 22 von sechs Transportklammern 16 entsprechend sechs aufeinanderfolgenden Taktabständen angedeutet. Dazwischen ist strichpunktiert die Lage von Druckereiprodukten 26 angedeutet, die sie mittig zwischen einzelnen Takten einnehmen. Die Druckereiprodukte 26 liegen mit ihrem Randbereich 44 auf den Stützbändchen 42 mit ihrem nach vorne gebogenen Randbereich 44 auf. Infolge Reibungsmitnahme zwischen den bezüglich der Transportklammern 16 mit grösserer Geschwindigkeit vs angetriebenen Stützbändchen 42 und den Druckereiprodukten 26 werden diese in Förderrichtung F nach vorne gedrängt und kommen mit ihrer offenen Kante 34 zum Ausrichten an Nocken 98' zur Anlage. Da diese mit geringerer Geschwindigkeit vn als die Transportklammern 16 umlaufen, werden die Druckereiprodukte 26 S-förmig gebogen, was diesen Stabilität vermittelt. Es wird dann von der Seite her ein Tragarm 70 zwischen jeweils zwei Druckereiprodukte 26 eingeschwenkt, wodurch sich das betreffende Oeffnungselement 72 entlang dem schraubenlinienartigen Bewegungsbahnabschnitt 108' auf den obenliegenden zweiten Produkteteil 32 im Randbereich 44 des, in Förderrichtung F gesehen, dem Tragarm 70 nachlaufenden Druckereiprodukts 26 absenkt. Die Synchronisation zwischen dem Tragelement 62 und der Saugwalze 46 ist derart gewählt, dass jeweils ein Saugkopf 50 der Saugwalze 46 und ein Oeffnungselement 72 das Druckereiprodukt 26 im Randbereich 44 zwischen sich aufnehmen. Der von unten an den ersten Produkteteil 30 in Anlage gebrachte Saugkopf 50 und das entsprechende Oeffnungselement 72 werden mit der Unterdruckquelle verbunden, um den ersten bzw. zweiten Produkteteil 30,32 festzuhalten. Durch das Drehen der Saugwalze 46 wird nun der erste Produkteteil 30 um diese gebogen und der obenliegende zweite Produkteteil 32 im wesentlichen in Förderrichtung F entlang dem Bewegungsbahnabschnitt 97' des Oeffnungselements 72 weiterbewegt. Infolge des Umbiegens des ersten Produkteteils 30 um die Saugwalze 46 und die Bewegung des betreffenden Oeffnungselements 72 wird die S-förmige Biegung im Druckereiprodukt 26 im wesentlichen aufgehoben. Zwischen die voneinander abgehobenen Produkteteile 30,32 sticht von unten das Offenhalteelement 102 ein, wonach zuerst der Saugkopf 50 und dann das Oeffnungselement 72 belüftet wird, um die entsprechenden Produkteteile 30,32 freizugeben. Beim Weitertransport werden durch den jeweils zwischen die Produkteteile 30,32 eingreifenden Abschnitt 102' des Offenhaltelements 102 die Druckereiprodukte 26 offengehalten. Nach dem Belüften des Oeffnungselements 72 wird der betreffende Tragarm 70 in die Ruhelage 78 zurückverschwenkt, wobei das Oeffnungselement 72 entlang einem schraubenlinienartigen Bewegungsbahnabschnitt 108'' folgt. Wie Fig. 1 zeigt, greift jeweils von unten eine sattelartige Auflage 106 der Verarbeitungstrommel 24 zwischen die voneinander abgehobenen Produkteteile 30,32 eines Druckereiproduktes 26 ein, worauf durch Oeffnen der entsprechenden Transportklammer 16 das Druckereiprodukt 26 rittlings auf die Auflage 106 fällt. The operation of the devices described will now be described in more detail in particular with reference to FIGS. 5 and 6. In these the clamp mouths 22 of six transport clamps 16 are indicated corresponding to six successive cycle intervals. In between, the position of printed products 26, which they occupy in the middle between individual cycles, is indicated by dash-dotted lines. The printed products 26 rest with their edge area 44 on the support tapes 42 with their edge area 44 bent forward. As a result of the frictional entrainment between the support bands 42, which are driven at a higher speed v s with respect to the transport clamps 16, and the printed products 26, these are pushed forward in the conveying direction F and come into contact with their open edge 34 for alignment with cams 98 '. Since these rotate at a lower speed v n than the transport clamps 16, the printed products 26 are bent in an S-shape, which gives them stability. A support arm 70 is then pivoted in from the side between two printed products 26 in each case, as a result of which the relevant opening element 72 moves along the helical movement path section 108 ′ onto the second product part 32 located above in the edge region 44 of the printed product trailing the support arm 70 in the conveying direction F 26 lowers. The synchronization between the support element 62 and the suction roller 46 is selected such that a suction head 50 of the suction roller 46 and an opening element 72 receive the printed product 26 in the edge region 44 between them. The suction head 50, which is brought into contact with the first product part 30 from below, and the corresponding opening element 72 are connected to the vacuum source in order to hold the first and second product parts 30, 32 in place. By rotating the suction roller 46, the first product part 30 is then bent around it and the second product part 32 located above it is moved essentially in the conveying direction F along the movement path section 97 ′ of the opening element 72. As a result of the first product part 30 being bent over the suction roller 46 and the movement of the opening element 72 in question, the S-shaped bend in the printed product 26 is essentially eliminated. The hold-open element 102 pierces between the product parts 30, 32 lifted from one another, after which the suction head 50 and then the opening element 72 are ventilated in order to release the corresponding product parts 30, 32. During further transport, the printed products 26 are kept open by the section 102 ′ of the hold-open element 102 that engages between the product parts 30, 32. After ventilation of the opening element 72, the relevant support arm 70 is pivoted back into the rest position 78, the opening element 72 following along a helical movement path section 108 ″. As shown in FIG. 1, a saddle-like support 106 of the processing drum 24 engages between the separated product parts 30, 32 of a printed product 26 from below, whereupon the printed product 26 falls astride the support 106 by opening the corresponding transport clamp 16.

Es sei erwähnt, dass selbstverständlich immer zwischen zwei aufeinanderfolgende Druckereiprodukte 26 ein Tragarm 70 eingeschwenkt wird, in den Fig. 5 und 6 aber der besseren Uebersichtlichkeit halber jeweils nur ein Tragarm 70 in ausgezogenen Linien, in vier aufeinanderfolgenden Arbeitstakten und strichpunktiert beim Oeffnen mittig zwischen zwei Arbeitstakten gezeigt ist. Da die Nocken 98' mit grösserer Geschwindigkeit vn umlaufen als die Saugköpfe 50 (vu), entfernen sich jene von der Kante 34 der Druckereiprodukte 26, sobald dieses von einem Saugkopf 50 und einem Oeffnungselement 72 erfasst ist. Dadurch ist sichergestellt, dass das Oeffnen der Druckereiprodukte 26 durch die Nocken 98' nicht behindert wird. Auch wenn diese in Förderrichtung F gesehen, im Bereich des oberen richtaktiven Trums nach rückwärts geneigt angeordnet sind, um den Kanten 34 gesicherten Halt zu vermitteln. It should be mentioned that, of course, a support arm 70 is always swiveled in between two successive printed products 26, but in FIGS. 5 and 6 only one support arm 70 in solid lines, in four successive work cycles and in dash-dot lines between two in open lines, for the sake of clarity Working cycles is shown. Since the cams 98 'rotate at a greater speed v n than the suction heads 50 (v u ), they move away from the edge 34 of the printed products 26 as soon as this is gripped by a suction head 50 and an opening element 72. This ensures that the opening of the printed products 26 is not hindered by the cams 98 '. Even if these are viewed in the direction of conveyance F, they are arranged in the region of the upper directionally active strand inclined backwards in order to provide the edges 34 with secure hold.

Selbstverständlich ist die Antriebswelle 60 zur Fördereinrichtung 10 synchronisiert, ihre gegenseitige Phasenlage einstellbar. Weiter ist das Stützelement 38 und das Oeffnungsaggregat 36 in vertikaler Richtung höhenverstellbar, um eine Anpassung an unterschiedlich formatige Druckereiprodukte 26 zu gewährleisten. Of course, the drive shaft 60 is to the conveyor 10 synchronized, their mutual phase position adjustable. Next is the support member 38 and that Opening unit 36 vertically adjustable in height, to adapt to different formats To ensure printed products 26.

Wie dies insbesondere aus den Fig. 2 und 3 hervorgeht, ist der dem Oeffnungsaggregat 36 zugewandte Seitenrand 110 der Druckereiprodukte 26, in Richtung der Hohlwelle 48 gesehen, zwischen der Saugwalze 46 und dem Tragelement 62 angeordnet, so dass sich dieses und die sich in Ruhelage 78 befindenden Tragarme 70 mit den Oeffnungselementen 72 an den Druckereiprodukten 26 seitlich vorbeibewegen können. Daraus geht auch hervor, dass mittels dem vorliegenden Oeffnungsaggregat 36 die Druckereiprodukte 26 von durch den Seitenrand 110 und die Kante 34 gebildeten Eckbereiche her geöffnet werden. As can be seen in particular from FIGS. 2 and 3 the side edge 110 facing the opening unit 36 Printed products 26, viewed in the direction of the hollow shaft 48, arranged between the suction roller 46 and the support element 62, so that this and the at rest 78 support arms 70 with the opening elements 72 can move the printed products 26 sideways. It also follows that by means of the present Opening unit 36, the printed products 26 by the side edge 110 and the edge 34 formed corner areas be opened here.

Es ist selbstverständlich auch denkbar, Druckereiprodukte 26 etwa von der Mitte der offener Kante 34 her zu öffnen. In diesem Fall wäre die Saugwalze 46 in entsprechender Position anzuordnen, sowie der das Oeffnungselement 72 haltende Teil des Tragarms 70 entsprechend zu verlängern. Es ist auch denkbar, sowohl die Saugköpfe 50 als auch die Tragarme 70 an einem endlosen umlaufenden Zugorgan anzuordnen. Ebenso ist es möglich, die Oeffnungselemente 72 an Tragarmen anzuordnen, die an einem entsprechenden Tragelement translatorisch verschiebbar gelagert sind. Of course, it is also conceivable to print products 26 open approximately from the center of the open edge 34. In this case, the suction roller 46 would be in the appropriate position   to be arranged, as well as the one holding the opening element 72 To extend part of the support arm 70 accordingly. It is also conceivable, both the suction heads 50 and To arrange support arms 70 on an endless rotating traction element. It is also possible to open the opening elements 72 Arrange support arms on a corresponding support element are mounted in a translationally displaceable manner.

Die erfindungsgemässe Vorrichtung eignet sich insbesondere zum Oeffnen von gefalteten Einzelbogen, die beispielsweise die Titel- und die Rückseite einer Zeitschrift bilden, und von 2-Falzprodukten, die ein erstes Mal gefaltet und rechtwinklig dazu ein zweites Mal gefaltet worden sind, wobei sie beim zuletzt gebildeten Falz 28 von den Transportklammern gehalten transportiert werden und der erstgebildete Falz den dem Oeffnungsaggregat 36 zugewandten Seitenrand 110 bildet. The device according to the invention is particularly suitable to open folded single sheets, for example form the title and back of a magazine, and of 2-fold products that folded and a first time have been folded a second time at right angles to it, where at the last fold 28 formed by the transport clips kept transported and the first educated Fold the side edge facing the opening unit 36 110 forms.
