Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abheben von Druckereierzeugnissen von einem Stapel gemäss Oberbegriff des Anspruches 1 bzw. 2.The present invention relates to a method and a Device for lifting printed matter from one Stack according to the preamble of claim 1 or 2.

Aus der DE-C-27 32 591 ist eine Einrichtung zum Abbauen eines Stapels von Druckereierzeugnissen dieser Art bekannt, bei der der Saugkopf mittels eines Antriebsmechanismus entlang einer geschlossenen Umlaufbahn bewegt wird, deren Form einer Hypozykloide ähnlich ist. In einem oberen Umkehrpunkt dieser Bewegungsbahn erfasst der Saugkopf eine Ecke des jeweils untersten Druckereierzeugnisses im Stapel und nimmt diese Ecke bis zum nächsten, unteren Umkehrpunkt mit. Der Antriebsmechanismus, der ein mit einem Antriebsmotor mit konstanter Drehzahl verbundenes Planetengetriebe aufweist, ist nun in erster Linie dazu da, den Saugkopf entlang der erwähnten, eine bestimmte Form aufweisenden Bewegungsbahn zu bewegen. Zwar ändert sich die Geschwindigkeit des Saugkopfes während seiner Bewegung entlang der Bewegungsbahn, doch sind die auftretenden Geschwindigkeitsänderungen an die Konstruktion des Antriebsmechanismus und damit an die Form der Bewegungsbahn gebunden.From DE-C-27 32 591 is a device for dismantling a stack known from printed matter of this type, in which the Suction head along a drive mechanism closed orbit is moved, the shape of a Hypocycloid is similar. At an upper turning point the suction head captures a corner of the lowest printed product in the stack and takes this corner to the next lower reversal point with. Of the Drive mechanism that one with a drive motor with planetary gear connected at constant speed, is primarily there to move the suction head along the mentioned, having a certain shape trajectory to move. Although the speed of the Suction head during its movement along the trajectory, yet the occurring speed changes to the construction of the drive mechanism and thus bound the shape of the trajectory.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, das bzw. die es ermöglicht, die Geschwindigkeit des Saugkopfes während dessen Bewegung entlang seiner Bahn in weiten Grenzen und unabhängig von der Form der Bewegungsbahn zu varieren. The present invention is based on the object a method and an apparatus of the aforementioned To create the kind that enables the Speed of the suction head during its movement along its path in wide limits and regardless of to vary the shape of the trajectory.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 bzw. 2 gelöst.This object is achieved by the features of characterizing part of claim 1 and 2 solved.

Der erfindungsgemässen Lösung liegt nun die Erkenntnis zugrunde, die Bewegungsgeschwindigkeit des Saugkopfes, wie sie durch den von einem Antriebsmotor mit konstanter Drehzahl her angetriebenen Antriebsmechanismus gegeben ist, mittels eines Zwischengetriebes, das zwischen den Antriebsmotor und den Antriebsmechanismus geschaltet ist, zu beeinflussen. Somit ist es möglich, bei einer gegebenen Form der Bewegungsbahn, die durch den Antriebsmechanismus bestimmt ist, ohne Beeinflussung dieser Bewegungsbahn die Bewegungsgeschwindigkeit des Saugkopfes zu variieren, und zwar so, dass die Geschwindigkeit des Saugkopfes beim Erfassen eines Druckereierzeugnisses minimal ist und beim darauf unmittelbar folgenden Mitnehmen zunimmt. Damit kann vermieden werden, dass das nachfolgende Erzeugnis beim Abheben des Druckereierzeugnisses vom Stapel durch Sogwirkung mitgerissen wird.The solution according to the invention is now based on the knowledge that Speed of movement of the suction head, as by the one Drive motor driven at constant speed Drive mechanism is given by means of an intermediate gear, the is connected between the drive motor and the drive mechanism influence. Thus it is possible, given a form of the Trajectory that is determined by the drive mechanism without Influencing this trajectory the speed of movement To vary the suction head so that the speed of the Suction head when capturing a printed product is minimal and when immediately following take away increases. This can be avoided be that the subsequent product when the Printed product is entrained from the stack by suction.

In den Figuren 1 und 2 ist mit 1 ein Stapel bezeichnet, der durch gefaltete Druckereierzeugnisse 2 gebildet ist. Letztere werden durch einen Zuförderer 3 in einer Schuppenformation S zugebracht, in der jedes Druckereierzeugnis 2 auf dem nachlaufenden Druckereierzeugnis aufliegt. Dies bedeutet, dass die nachlaufende Kante 2a, die bei der vorliegenden Ausführungsform die Falzkante ist, in der Schuppenformation S oben liegt. Die Druckereierzeugnisse 2 werden von unten in den Stapel aufgeschoben, wie das in der EP-A-0 551 601 näher erläutert ist.In Figures 1 and 2, 1 denotes a stack that is formed by folded printed products 2. The latter are in a by a feed conveyor 3 Shed formation S in which each Printed product 2 on the trailing Printed product rests. This means that the trailing edge 2a, which in the present Embodiment is the folded edge, in the scale formation S is on top. The printed products 2 are from below pushed into the stack, as in EP-A-0 551 601 is explained in more detail.

Zum Abheben des jeweils obersten Druckereierzeugnisses 2 vom Stapel 1 ist ein nur schematisch dargestellter Saugkopf 4 vorhanden, der auf an sich bekannte Weise periodisch an eine nicht näher dargestellte Unterdruckquelle anschliessbar ist. Der Saugkopf 4 wird mittels eines Antriebsmechanismus 5 entlang einer geschlossenen, birnenförmigen Umlaufbahn 6 bewegt. An einer Uebernahmestelle 7, die sich an der Spitze der Umlaufbahn 6 befindet, erfasst der Saugkopf 4 das jeweils oberste Druckereierzeugnis 2 im Bereich dessen Falzkante 2a und hebt das erfasste Druckereierzeugnis während der Bewegung entlang des Abschnittes 6a der Umlaufbahn 6 vom Stapel 1 ab. An der mit 8 bezeichneten Abgabestelle wird durch Wegschalten des Unterdruckes das mitgenommene Druckereierzeugnis 2 abgegeben. Anschliessend läuft der Saugkopf 4 in Umlaufrichtung U weiter. Das jeweils abgegebene Druckereierzeugnis 2 wird von einem Wegförderer übernommen, wie das in der bereits erwähnten EP-A-0 551 601 ausführlicher beschrieben ist.To lift the top printed product 2 from stack 1 is a suction head shown only schematically 4 available, the periodically in a manner known per se a vacuum source, not shown can be connected. The suction head 4 is by means of a Drive mechanism 5 along a closed, pear-shaped orbit 6 moves. At a Takeover point 7, which is at the top of the orbit 6 is located, the suction head 4 detects the top one Printed product 2 in the area of its folded edge 2a and lifts the captured printed product during the movement along section 6a of orbit 6 from stack 1 from. At the delivery point designated by 8 is by Switching off the negative pressure the entrained Printed product 2 delivered. Then the Suction head 4 continues in the direction of rotation U. That in each case The printed product 2 is delivered by a conveyor taken over, like that in the already mentioned EP-A-0 551 601 in more detail is described.

Im folgenden wird nun der Aufbau und die Wirkungsweise des Antriebsmechanismus 5 näher erläutert.The structure and mode of operation of the Drive mechanism 5 explained in more detail.

Wie insbesondere die Figur 2 zeigt, ist der Saugkopf 4 an einem Tragrohr 9 befestigt, das über eine nicht dargestellte Schlauchleitung mit der bereits erwähnten zu- und wegschaltbaren Unterdruckquelle verbunden ist. Dieses Tragrohr 9 ist am einen Arm 10a eines zweiarmigen Hebels 10 befestigt, dessen anderer Arm 10b gegenüber dem Arm 10a abgewinkelt ist. Der Arm 10b bildet die Koppel einer Kurbelschwinge 11 und ist über ein Gelenk 12, dessen Gelenkzapfen mit 12a bezeichnet ist, mit einer Kurbel 13 verbunden. Letztere sitzt auf einer in Richtung des Pfeiles A umlaufend angetriebenen Welle 14, die in einem Lager 15 drehbar gelagert ist. Die Welle 14, deren Längsachse mit 14' bezeichnet ist, wird von einer anhand der Figuren 3 und 4 noch zu beschreibenden Antriebseinrichtung angetrieben. Am anderen Ende ist der Arm 10b des Hebels 10 über ein Gelenk 16, dessen Gelenkzapfen mit 16a bezeichnet ist, mit einer Schwinge 17 verbunden. Letztere ist auf einer Welle 18 befestigt, die frei drehbar in einem Lager 19 gelagert ist. Die Längsachse dieser Welle 18 ist mit 18' bezeichnet. As FIG. 2 in particular shows, the suction head 4 is on attached to a support tube 9, which does not have a shown hose line with the already mentioned and switchable vacuum source is connected. This Support tube 9 is on one arm 10a of a two-armed lever 10 attached, the other arm 10b opposite the arm 10a is angled. The arm 10b forms the coupling one Crank arm 11 and is via a joint 12, the The pivot pin is designated 12a, with a crank 13 connected. The latter sits on one in the direction of the arrow A rotating shaft 14, which in a bearing 15 is rotatably mounted. The shaft 14, the longitudinal axis with 14 'is designated by one with reference to Figures 3 and 4 driven drive device to be described. At the other end, the arm 10b of the lever 10 is over one Joint 16, whose pivot pin is designated 16a with a rocker 17 connected. The latter is on a wave 18 attached, which is freely rotatable in a bearing 19 is. The longitudinal axis of this shaft 18 is designated 18 '.

Die Schwinge 17 wird bei sich drehender Kurbel 13 zwischen zwei Endstellungen, die in Figur 1 strichpunktiert dargestellt sind und einen Winkel α einschliessen, hin und her verschwenkt. Die beiden Endlagen der Schwinge 17 sind durch die mit 16a' und 16a'' bezeichneten Positionen des Gelenkzapfens 16a bezeichnet. Die diesen Endlagen 16a' und 16a'' zugeordneten Positionen des Gelenkzapfens 12a sind mit 12a' und 12a'' bezeichnet.The rocker 17 is between the rotating crank 13 two end positions, dash-dotted in Figure 1 are shown and include an angle α, back and forth pivoted here. The two end positions of the rocker 17 are by the positions of 16a 'and 16a' ' Designated pivot pin 16a. The these end positions 16a 'and 16a '' are assigned positions of the pivot pin 12a designated 12a 'and 12a' '.

Mittels des beschriebenen Hebelantriebsmechanismus 5 wird nun der Saugkopf 4 wie bereits erwähnt von der Uebernahmestelle 7 entlang des Abschnittes 6a der Umlaufbahn 6 nach oben zur Abgabestelle 8 bewegt. Zwischen Uebernahmestelle 7 und Abgabestelle 8 ist der Saugkopf 4 wie bereits erwähnt mit der Unterdruckquelle verbunden und nimmt jeweils das oberste Druckereierzeugnis 2 des Stapels 1 mit. Nach dem Wegschalten der Unterdruckquelle und dem dadurch erfolgten Freigeben des mitgenommenen Druckereierzeugnisses 2 wird der Saugkopf 4 weiter in Richtung des Pfeiles U entlang der Umlaufbahn 6 bewegt, bis er wieder zur Uebernahmestelle 7 gelangt, wo das nächste Druckereierzeugnis 2 erfasst wird.By means of the lever drive mechanism 5 described now the suction head 4 as already mentioned by the Takeover point 7 along section 6a of the Orbit 6 moved up to delivery point 8. Between The take-over point 7 and delivery point 8 is the suction head 4 as already mentioned connected to the vacuum source and takes the top printed product 2 of the stack 1 with. After switching off the vacuum source and the thereby releasing the taken away Printed product 2, the suction head 4 is further in Moved in the direction of arrow U along orbit 6 until he got back to takeover point 7, where the next one Printed product 2 is detected.

Damit der Saugkopf 4 entlang der gewünschten Bahn 6 bewegt wird, muss der Antriebsmechanismus 5 entsprechend ausgebildet sein. Durch diese spezielle Ausbildung des Antriebsmechanismus 5 ist auch der Verlauf der Geschwindigkeit, mit der sich der Saugkopf 4 entlang der Bewegungsbahn 6 bewegt, festgelegt. Um nun diesen durch die Konstruktion des Antriebsmechanismus 5 bestimmten Geschwindigkeitsverlauf beeinflussen zu können, ist dem Antriebsmechanismums 5 ein Zwischen- oder Ueberlagerungsgetriebe 20 vorgeschaltet, das nun anhand der Figuren 3 und 4 näher erläutert wird. So that the suction head 4 moves along the desired path 6 , the drive mechanism 5 must accordingly be trained. Through this special training of the Drive mechanism 5 is also the course of the Speed at which the suction head 4 along the Movement trajectory 6 moves, fixed. To get this through the Construction of the drive mechanism 5 determined It is to be able to influence the course of speed Drive mechanism 5 an intermediate or Superposition gear 20 upstream, which is now based on the Figures 3 and 4 is explained in more detail.

Dieses Zwischengetriebe 20, das im vorliegenden Fall als Kurbelgetriebe und im speziellen als umlaufende Kurbelschleife ausgebildet ist, weist ein Antriebsglied 21 auf, das von einem nur schematisch dargestellten Antriebsmotor 22 mit konstanter Drehzahl, d.h. mit konstanter Winkelgeschwindigkeit ω1, angetrieben wird. Das Antriebsglied 21 ist über Lager 23 um seine Achse 21' drehbar in einem Gehäuse 24 gelagert. Im Antriebsglied 21 ist ein Mitnahmeelement 25, das im vorliegenden Ausführungsbeispiel eine Rolle ist, befestigt, z.B. mittels einer Schraubverbindung. Die Längsachse 25' des Mitnahmeelementes 25 verläuft parallel zur Drehachse 21' des Antriebsgliedes 21 und ist gegenüber letzterer um den Abstand r versetzt. Anders ausgedrückt ist das Mitnahmeelement 25 exzentrisch angeordnet.This intermediate gear 20, which in the present case is designed as a crank gear and in particular as a revolving crank loop, has a drive member 21 which is driven by a drive motor 22, shown only schematically, at constant speed, ie at constant angular velocity ω 1 . The drive member 21 is mounted in a housing 24 via bearings 23 rotatable about its axis 21 '. A drive element 25, which is a roller in the present exemplary embodiment, is fastened in the drive member 21, for example by means of a screw connection. The longitudinal axis 25 'of the driving element 25 runs parallel to the axis of rotation 21' of the drive member 21 and is offset by the distance r from the latter. In other words, the driving element 25 is arranged eccentrically.

Das Mitnahmeelement 25 ist in einer Quernut 26 geführt, die in einem Abtriebsglied 27 ausgebildet ist. Dieses Abtriebsglied 27 sitzt mit einem Verbindungsteil 27a auf der Welle 14 des Antriebsmechanismus 5. Die Drehachse 27' des Abtriebsgliedes 27 fluchtet somit mit der Drehachse 14' der Welle 14, ist jedoch gegenüber der Drehachse 21' des Antriebsgliedes 21 um den Betrag e versetzt.The driving element 25 is guided in a transverse groove 26 which is formed in an output member 27. This Output member 27 is seated with a connecting part 27a the shaft 14 of the drive mechanism 5. The axis of rotation 27 ' of the output member 27 is thus aligned with the axis of rotation 14 ' the shaft 14, however, is opposite the axis of rotation 21 'of the Drive member 21 offset by the amount e.

Das wie erwähnt als umlaufende Kurbelschleife ausgebildete Zwischengetriebe 20 formt nun die konstante Antriebsgeschwindigkeit des Motors 22 in eine sich periodisch ändernde Antriebsgeschwindigkeit für den Antriebsmechanismus 5 um. In Figur 5 ist der Verlauf der Winkelgeschwindigkeit ω in Abhängigkeit von der Zeit t durch die Kurve 28 dargestellt. Während die Winkelgeschwindigkeit ω1 am Eingang des Zwischengetriebes 20 konstant ist, ändert sich die Winkelgeschwindigkeit ω2, mit der die Welle 14 des Antriebsmechanismus 5 angetrieben wird, zwischen einem Minimalwert 28a und einem Maximalwert 28b. In Figur 4 sind mit 29a und 29b die Stellungen des Zwischengetriebes 20 angegeben, in denen das Minimum (Stellung 29a) und das Maximum (Stellung 29b) der Winkelgeschwindigkeit ω2 auftritt. Es versteht sich, dass die Lage der Stellungen 29a, 29b beliebig gewählt werden können.The intermediate gear 20 designed as a rotating crank loop, as mentioned, now converts the constant drive speed of the motor 22 into a periodically changing drive speed for the drive mechanism 5. 5 shows the course of the angular velocity ω as a function of the time t by the curve 28. While the angular velocity ω 1 at the input of the intermediate gear 20 is constant, the angular velocity ω 2 with which the shaft 14 of the drive mechanism 5 is driven changes between a minimum value 28a and a maximum value 28b. In Figure 4, 29a and 29b indicate the positions of the intermediate gear 20 in which the minimum (position 29a) and the maximum (position 29b) of the angular velocity ω 2 occur. It goes without saying that the positions of the positions 29a, 29b can be chosen as desired.

Die minimale Winkelgeschwindigkeit ω2 ergibt sich aus der Formel ω2 = rr+e x ω1, während sich die maximale Winkelgeschwindigkeit ω2 aus der Formel ω2 = rr-e x ω1 ergibt.The minimum angular velocity ω 2 results from the formula ω 2nd = r r + e x ω 1 , while the maximum angular velocity ω 2 is from the formula ω 2nd = r re x ω 1 results.

Der vom Zwischengetriebe 20 wie beschrieben erzeugte Geschwindigkeitsverlauf wird somit dem Geschwindigkeitsverlauf überlagert, der durch die Konstruktion des Antriebsmechanismus 5 bestimmt ist. Diese Geschwindigkeitsüberlagerung erfolgt nun so, dass die Bewegungsgeschwindigkeit des Saugkopfes 4 im Bereich der Uebernahmestelle 7, d.h. beim unmittelbar an das Erfassen anschliessenden Anheben eines Druckereierzeugnisses 2, minimal ist und dann zunimmt. Dadurch wird einerseits ein einwandfreies Erfassen des jeweils obersten Druckereierzeugnisses 2 des Stapels 1 sichergestellt und andererseits vermieden, dass beim Abheben des erfassten Druckereierzeugnisses 2 das nachfolgende Druckereierzeugnis 2 infolge Sogwirkung mitgerissen wird.The speed profile generated by the intermediate gear 20 as described thus becomes the speed curve overlaid by the construction of the Drive mechanism 5 is determined. This The speed overlap is now such that the Movement speed of the suction head 4 in the area of Takeover point 7, i.e. when immediately capturing subsequent lifting of a printed product 2, is minimal and then increases. This makes one flawless detection of the top one Secured printed product 2 of the stack 1 and on the other hand avoided that when lifting the captured Printed matter 2 the following Printed product 2 is entrained as a result of suction.

Anhand der sehr schematischen Darstellung der Figur 6 wird nun eine andere Ausführungsform einer Vorrichtung zum Abheben der Druckereierzeugnisse 2 vom Stapel 1 beschrieben, die sich von der Ausführungsform gemäss den Figuren 1 und 2 durch eine andere Ausbildung des Antriebsmechanismus für den Saugkopf 4 unterscheidet. Based on the very schematic representation of Figure 6 now another embodiment of a device for Lifting the printed products 2 from the stack 1 described, which differ from the embodiment according to Figures 1 and 2 by a different design of Drive mechanism for the suction head 4 differs.

Der Saugkopf 4 ist ebenfalls an einem nur schematisch angedeuteten Tragrohr 30 befestigt, das wie anhand der Figuren 1 und 2 beschrieben über eine nicht gezeigte Schlauchleitung mit einer Unterdruckquelle verbunden ist. Dieser Tragarm 30 ist mit einem Antriebsmechanismus 31 verbunden, der einen Hebel 32 aufweist, mit dem das Tragrohr 30 fest verbunden ist. Dieser Hebel 32 steht an beiden Enden über Gelenke 33 und 34 mit weiteren Hebeln in Verbindung. Mittels des Gelenkes 33 ist der Hebel 32 mit einem Hebel 35 verbunden, der in einem Lager 36 schwenkbar gelagert ist. Ueber das andere Gelenk 34 steht der Hebel 32 mit einem zweiarmigen Hebel 37 in Verbindung, der schwenkbar in einem Lager 38 gelagert ist. Der zweiarmige Hebel 37 ist am anderen Ende über ein weiteres Gelenk 39 mit der Koppel 40 eines Kurbelantriebes verbunden, welche über ein Gelenk 41 mit einer Kurbel 42 verbunden ist. Letztere sitzt auf einer nur schematisch angedeuteten Welle 43, die mit dem Abtriebsglied 27 des Zwischengetriebes 20 verbunden ist. Die Kurbel 42 läuft somit mit der Winkelgeschwindigkeit ω2, deren Verlauf in Figur 5 dargestellt ist, in Richtung des Pfeiles B um.The suction head 4 is also attached to a support tube 30, which is only indicated schematically and which, as described with reference to FIGS. 1 and 2, is connected to a vacuum source via a hose line (not shown). This support arm 30 is connected to a drive mechanism 31 which has a lever 32 with which the support tube 30 is fixedly connected. This lever 32 is connected at both ends via joints 33 and 34 to other levers. By means of the joint 33, the lever 32 is connected to a lever 35 which is pivotally mounted in a bearing 36. Via the other joint 34, the lever 32 is connected to a two-armed lever 37, which is pivotably mounted in a bearing 38. The two-armed lever 37 is connected at the other end via a further joint 39 to the coupling 40 of a crank drive, which is connected to a crank 42 via a joint 41. The latter is seated on a shaft 43, which is only indicated schematically and which is connected to the output member 27 of the intermediate gear 20. The crank 42 thus rotates at the angular velocity ω 2 , the course of which is shown in FIG. 5, in the direction of the arrow B.

Das Verbindungsgelenk 41 zwischen der Kurbel 42 und der Kuppel 40 läuft dementsprechend entlang einer kreisförmigen Bahn 44 um. Der Hebel 37 führt dabei eine Schwenkbewegung um die Achse seines Lagers 38 aus. Die beiden Endlagen des Hebels 37 sind einerseits mit einer ausgezogenen Linie und andererseits mit einer strichpunktierten Linie dargestellt. Die beiden Gelenke 34 und 39 des Hebels 37 bewegen sich dabei entlang der Bahnen 45 und 46 zwischen den Punkten I und II hin und her. Der Hebel 35 schwingt von der mit einer ausgezogenen Linie dargestellten Stellung in die strichpunktiert dargestellte Stellung und wieder zurück, wobei sich das Gelenk 33 entlang der Bahn 47 zwischen den Punkten I' und II' hin und her bewegt. Durch diese Schwingbewegung der Hebel 37 und 35 ergibt sich auch die Bewegung des Hebels 32, an dem wie erwähnt fest das Tragrohr 30 des Saugkopfes 2 angebracht ist. Der Saugkopf 2 wird dadurch von einer Uebernahmestelle 48 entlang der leicht gekrümmten Bewegungsbahn 49 zu einer Abgabestelle 50 und auf derselben Bahn 49 wieder zurück zur Uebernahmestelle 48 bewegt. An der Uebernahmestelle 48 erfasst der nun an die Unterdruckquelle angeschlossene Saugkopf 4 das jeweils oberste Druckereierzeugnis 2 im Stapel 1 und nimmt dieses bis zur Abgabestelle 50 mit, an der durch Wegschalten der Unterdruckquelle das mitgenommene Druckereierzeugnis 2 freigegeben wird. An dieser Abgabestelle 50 wird das vom Saugkopf 4 freigegebene Druckereierzeugnis 2 von einem Wegförderer übernommen, wie das in der schon früher erwähnten EP-A-0 551 601 ausführlicher beschrieben ist.The connecting joint 41 between the crank 42 and the Accordingly, dome 40 runs along a circular path Orbit 44 around. The lever 37 performs a pivoting movement around the axis of its bearing 38. The two end positions of the Levers 37 are on the one hand with a solid line and on the other hand, shown with a dash-dotted line. The two joints 34 and 39 of the lever 37 move thereby along the lanes 45 and 46 between points I and II back and forth. The lever 35 swings with one solid line shown position in the dash-dotted position and back again, the hinge 33 along the path 47 between the Points I 'and II' moved back and forth. Through this Swinging movement of the levers 37 and 35 also results in the Movement of the lever 32 on which, as mentioned, firmly Support tube 30 of the suction head 2 is attached. The suction head 2 is thereby taken from a takeover point 48 along the slightly curved path 49 to a delivery point 50 and on the same track 49 back to Takeover point 48 moves. At the takeover point 48 detects the one now connected to the vacuum source Suction head 4 the uppermost printed product 2 in each Stack 1 and takes it to the delivery point 50 the taken away by switching off the vacuum source Printed product 2 is released. At this Delivery point 50 is released by the suction head 4 Printed product 2 taken over by a conveyor, such as that in the previously mentioned EP-A-0 551 601 is described in more detail.

Auch bei der Ausführungsform gemäss Fig. 6 wird wie anhand der Figuren 1-5 beschrieben der Bewegungsgeschwindigkeit des Saugkopfes 4, die durch den Antriebsmechanismus 31 gegeben ist, die sich ändernde Antriebsgeschwindigkeit des Zwischengetriebes 20 überlagert, so dass die Bewegungsgeschwindigkeit des Saugkopfes 4 im Bereich der Uebernahmestelle 48 beim unmittelbar auf das Erfassen folgenden Abheben eines Druckereierzeugnisses 2 minimal ist und dann zunimmt.In the embodiment according to FIG. 6, too, is how of Figures 1-5 described the speed of movement of the suction head 4 by the drive mechanism 31 is given, the changing drive speed of the Intermediate gear 20 superimposed so that the Movement speed of the suction head 4 in the area of Takeover point 48 when directly on the detection subsequent withdrawal of a printed product 2 is minimal and then increases.

Mit demselben Zwischengetriebe 20 kann somit bei verschieden ausgebildeten Antriebsmechanismen 5,31 der gewünschte Geschwindigkeitsverlauf für den Saugkopf 4 erzielt werden. With the same intermediate gear 20 can thus differently designed drive mechanisms 5.31 the desired speed curve for the suction head 4 be achieved.

Es ist auch möglich, das Zwischengetriebe 20 von der anderen Seite her, d.h. vom Glied 27 her, anzutreiben. Letzteres wird dann zum mit dem Motor 22 gekoppelten Antriebsglied, während die Antriebswelle 14,43 des Antriebsmechanismus 5,31 mit dem nun als Abtriebsglied wirkenden Glied 21 verbunden ist.It is also possible to remove the intermediate gear 20 from the other side, i.e. from link 27 to drive. The latter is then coupled to the motor 22 Drive member, while the drive shaft 14.43 des Drive mechanism 5.31 with the now as an output member acting link 21 is connected.

Die erfindungsgemässe Lösung lässt sich auch bei Ausführungsformen verwenden, bei denen die Druckereierzeugnisse nicht wie vorstehend beschrieben von oben vom Stapel abgehoben werden, sondern von unten vom Stapel abgezogen werden, wie das z.B. in der DE-C-27 32 591 beschrieben ist.The solution according to the invention can also be used for Use embodiments in which the Printed matter not as described above by be lifted off the top of the stack, but from below Stacks are withdrawn, such as e.g. in DE-C-27 32 591 is described.
