Abstract

The method involves supplying printed sheets to a conveying device (4) of a stack support (3), and perpendicularly arranging the sheets on the support to form a stack (5). The stack is supported at a side by a supporting device (7), and the stack is transferred to a pressing device with two press carriages (15, 16). The stack is pressed between the carriages to form a pressed stack (5'), and the stack (5') is strapped. One of the carriages is moved to another stack formed on the support after the strapping of the stack (5'), and the latter stack is supported at the side by the device (7). An independent claim is also included for a device for manufacturing a stack of printed sheet.

Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Stapeln aus fortlaufend einer sich horizontal erstreckenden Stapelauflage zugeführten, senkrecht aneinander gereihten Druckbogen, mit einer die Druckbogen der Stapelauflage zuführenden Fördervorrichtung und einer zum Bilden eines Stapels in einen sich bildenden Stapel eingreifenden Stützvorrichtung, mit welcher ein sich bildender Stapel stützbar und einer Presseinrichtung übergebbar ist, die einen ersten und einen zweiten Presswagen aufweist, zwischen denen ein gebildeter Stapel abpressbar ist, wobei der erste Presswagen mit einer der Fördervorrichtung abgewendeten Rückseite an den abzupressenden Stapel anlegbar ist.The invention relates to a device for producing stacks of continuously fed to a horizontally extending stack support, vertically aligned printing sheet, with a printing sheet of the stack support feeding conveyor and a for forming a stack in a forming stack engaging support device, with which a forming Stack sustainable and a pressing device can be handed over, which has a first and a second compacting carriage, between which an educated stack can be pressed off, wherein the first compacting carriage with a back side facing away from the conveying device can be applied to the abzupressenden stack.

Nach der Druckmaschine werden Druckbogen für die Weiterverarbeitung zu Büchem, Zeitschriften und dergleichen als sogenannte Stangen gestapelt, siehe z.B. WO 2004/009 448 A1 . Zum Bilden der Stangen werden die Druckbogen im Schuppenstrom senkrecht von oben nach unten auf eine horizontale Stapelauflage gefördert. Der sich bildende Stapel bzw. die Stange wird hierbei an beiden Stapelseiten von einer Stützvorrichtung abgestützt. Hat der Stapel bzw. die Stange die gewünschte Länge erreicht, so wird dieser von der Stützvorrichtung an zwei Presswagen übergeben. Mit diesen beiden Presswagen wird der Stapel abgepresst und schliesslich umreift. Unter dem Umreifen eines Stapels wird jeder Vorgang verstanden, bei dem der abgepresste Stapel für den Weitertransport stabilisiert bzw. gehalten wird. Der umreifte Stapel wird der Weiterverarbeitung zugeführt, beispielsweise an einen Anleger übergeben. Während dem Abpressen und Umreifen eines Stapels wird auf der Stapelauflage gleichzeitig ein nächster Stapel gebildet.After the printing press sheets for further processing to Büchem, magazines and the like are stacked as so-called rods, see for example WO 2004/009 448 A1 , To form the rods, the sheets are conveyed in a shingled stream vertically from top to bottom on a horizontal stack support. The forming stack or rod is supported on both sides of the stack by a support device. If the stack or the rod has reached the desired length, it is transferred from the support device to two press carriages. The stack is pressed and finally strapped with these two compacts. By strapping a stack is meant any process in which the squeezed stack is stabilized for further transport. The strapped stack is sent for further processing, for example, handed over to a feeder. During the pressing and strapping of a stack, a next stack is simultaneously formed on the stack support.

An solche Verfahren werden hohe Anforderungen bezüglich der Zykluszeit und der Zuverlässigkeit gestellt, um die zugeführte Menge der Druckbogen verarbeiten zu können. Die Zykluszeit sollte möglichst kurz sein, ohne dass hierbei die Zuverlässigkeit beeinträchtigt wird.High demands are placed on such processes with regard to the cycle time and the reliability in order to be able to process the supplied quantity of the printed sheets. The cycle time should be as short as possible without compromising reliability.

Durch die EP-A-1 405 809 ist eine Vorrichtung bekannt geworden, die zur Verkürzung der Zykluszeit eine Stützvorrichtung aufweist, welche ein drittes, dem in Stapelförderrichtung vorderen Ende des Stapels zugeordnetes, anhebbares Stützelement aufweist. Das dritte Stützelement soll unabhängig von einem ersten und zweiten Stützelement entlang der Stapelauflage antreibbar gesteuert sein, wodurch mehr Handlungsfreiheit und eine höhere Produktionsleistung erwirkbar sein sollen. Die Stützvorrichtung dient auch als Trennvorrichtung zum Abtrennen eines nachfolgenden Stapels. Nachteilig ist der vergleichsweise komplexe Aufbau der Stütz- bzw. Trennvorrichtung.By the EP-A-1 405 809 a device has become known which, in order to shorten the cycle time, has a supporting device which has a third lifting element which is assigned to the front end of the stack in the direction of stacking conveying. The third support element is to be driven drivable independently of a first and second support element along the stack support, whereby more freedom of action and a higher production capacity to be achieved. The supporting device also serves as a separating device for separating a subsequent stack. A disadvantage is the comparatively complex structure of the support or separation device.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zu schaffen, welche ebenfalls eine kürzere Zykluszeit ermöglicht, jedoch kostengünstiger ist. Die Aufgabe ist gemäss Anspruch 1 dadurch gelöst,The invention is based on the object to provide a device which also allows a shorter cycle time, but is less expensive. The object is achieved according to claim 1 characterized

dass der erste Presswagen Stützelemente aufweist, mit denen ein sich bildender Stapel an einer von der Fördervorrichtung abgewendeten Stapelseite abstützbar ist. Eine solche Vorrichtung ermöglicht die Erstellung von aus Druckbogen bestehenden Stapeln in einer besonders kurzen Zykluszeit. Die Vorrichtung kann vergleichsweise kostengünstig hergestellt werden und ist trotzdem zuverlässig.in that the first compacting carriage has supporting elements with which a forming stack can be supported on a stacking side facing away from the conveying device. Such a device enables the creation of stacks consisting of printed sheets in a particularly short cycle time. The device can be manufactured comparatively inexpensively and is nevertheless reliable.

Nach einer Weiterbildung ist vorgesehen, dass der erste Presswagen zwei Pressorgane aufweist, die zum Abpressen eines auf der Stapelauflage gebildeten Stapels jeweils eine von der Fördervorrichtung abgewendete Rückseite aufweisen. Diese Pressorgane sind vorzugsweise in einem Abstand zueinander angeordnet und quer zur Stapelförderrichtung verfahrbar. Der Abstand zwischen den Pressorganen kann dadurch einfach an das Format der Druckbogen bzw. an die Breite des Stapels angepasst werden.According to a development, it is provided that the first compacting carriage has two pressing members, each of which has a rear side facing away from the conveying device for pressing off a stack formed on the stacking support. These pressing members are preferably arranged at a distance from each other and movable transversely to the stack conveying direction. The distance between the pressing members can be easily adapted to the format of the sheet or to the width of the stack.

Nach einer Weiterbildung ist vorgesehen, dass die Stützelemente wenigstens an einem der beiden Pressorgane, an dessen der Fördervorrichtung zugewendeten Seite angeordnet sind. Die Stützelemente können somit zusammen mit den Pressorganen quer zur Stapelförderrichtung verstellt werden. Vorzugsweise ist an jedem Pressorgan ein Stützelement angeordnet. Die Stützelemente sind vorzugsweise von einer inneren in eine äussere Stellung verfahrbar. In der äusseren Stellung beengen sie den Zwischenraum zwischen den Pressorganen nicht. Es können deshalb auch vergleichsweise breite Stapel gebildet werden, beispielsweise Stapel aus Doppelnutzen, d.h. aus zwei zusammenhängend hergestellten, gleichen Produkten, die erst in einem nachfolgenden Verfahrensschritt getrennt werden. Die Stützelemente können beispielsweise als Bügel, Platten oder dergleichen ausgebildet sein und verschwenkt, verschoben oder anderweitig zwischen den beiden Stellungen bewegt werden. Ihr Antrieb erfolgt beispielsweise mit einem Stellzylinder, wobei aber auch andere Antriebsmittel denkbar sind.According to a development it is provided that the support elements are arranged at least on one of the two pressing members, on which the conveyor device facing side. The support elements can thus be adjusted together with the pressing members transversely to the staple conveying direction. Preferably, a support element is arranged on each pressing element. The support elements are preferably movable from an inner to an outer position. In the outer position they do not restrict the space between the pressing organs. It is therefore also possible to form comparatively wide stacks, for example double-use stacks, i. from two cohesively produced, identical products, which are only separated in a subsequent process step. The support members may be formed, for example, as brackets, plates or the like and pivoted, moved or otherwise moved between the two positions. Your drive is done for example with a control cylinder, but other drive means are conceivable.

Die Vorrichtung 1 besitzt gemäss Figur 1 ein Maschinengestell 2, das eine sich horizontal erstreckende Stapelauflage 3 aufweist. Der Stapelauflage 3 werden mit einer Fördervorrichtung 4 Druckbogen 6 (Figur 8) aus einem Schuppenstrom in etwa senkrechter Richtung von oben zugeführt. Solche beispielsweise aus zwei Bändern bestehende Fördervorrichtungen 4 für Schuppenströme sind dem Fachmann gut bekannt und brauchen hier deshalb nicht weiter erläutert zu werden. Auf der Stapelauflage 3 wird durch Zuführung weiterer Druckbogen 6 ein stetig anwachsender Stapel 5 gebildet, der eine von der Fördervorrichtung 4 abgewandte sowie eine dieser zugewandte Stapelseite 38, 39 aufweist (Figur 3). Gemäss Figur 1 wird der Stapel 5 an der von der Fördervorrichtung 4 abgewendeten Stapelseite 38 von einem ersten Stütz- und Trennelement 8 einer Stützvorrichtung 7 abgestützt. Die Stützvorrichtung 7 besitzt ein zweites Stütz- und Trennelement 9, mit welchem dem sich bildenden Stapel 5 in an sich bekannter Weise eine zuvor in die Stapelauflage 3 eingeführte, erste Endplatte 10 zugeführt wird. Durch die Zufuhr weiterer Druckbogen 6 zur Stapelauflage 3 wandert die Stapelseite 38 in einer Stapelförderrichtung 13 nach rechts. Dementsprechend wird die Stützvorrichtung 7 beim Bilden des Stapels 5 zumindest zeitweise ebenfalls nach rechts bewegt.The device 1 has according to FIG. 1 a machine frame 2, which has a horizontally extending stack support 3. The stack support 3 are printed with a conveying device 4 6 ( FIG. 8 ) fed from a scale flow in approximately vertical direction from above. Such conveyor belts 4 for shingled streams, which consist for example of two belts, are well known to the person skilled in the art and therefore need not be further explained here. On the stack support 3, a continuously growing stack 5 is formed by supplying further printed sheets 6, which has a stack side 38, 39 which faces away from the conveying apparatus 4 and faces the same ( FIG. 3 ). According to FIG. 1 the stack 5 is supported on the stack side 38 away from the conveyor 4 by a first support and separation element 8 of a support device 7. The support device 7 has a second supporting and separating element 9, with which the forming stack 5 in a conventional manner a previously introduced into the stack support 3, the first end plate 10 is supplied. By supplying further printed sheets 6 to the stack support 3, the stack side 38 moves in a stack conveying direction 13 to the right. Accordingly, the support device 7 is at least temporarily also moved to the right when forming the stack 5.

Die Vorrichtung 1 besitzt zudem eine Presseinrichtung 29 mit einem ersten Presswagen 15 und einem zweiten Presswagen 16. Die beiden Presswagen 15 und 16 sind sowohl in als auch entgegen der Stapelförderrichtung 13 verfahrbar. Zwischen den beiden Presswagen 15 und 16 kann ein auf die oben beschriebene Weise gebildeter Stapel 5 in einem nachfolgenden Verfahrensschritt abgepresst, d.h. im Wesentlichen die zwischen den einzelnen Druckbogen 6 befindlichen Luftpolster ausgepresst und der Stapel 5 somit komprimiert werden. An die von der Fördervorrichtung 4 abgewendete Stapelseite 38 wird dazu die genannte ersten Endplatte 10 und an die der Fördervorrichtung 4 zugewendete Stapelseite 39 eine zweite Endplatte 11 angelegt, welche beispielsweise aus Holz bestehen. Die auf der rechten Seite der Figur 1 dargestellten Pfeile 32 deuten die Richtungen der Kräfte an, mit denen ein zuvor gebildeter Stapel 5 zu einem Stapel 5' abgepresst wird. Eine in diesem Bereich der Vorrichtung 1 angeordnete, dem Fachmann bekannte Umreifvorrichtung 12 dient zum Umreifen des abgepressten Stapels 5'. Die Art, wie der Stapel 5' umreift und damit stabilisiert wird, ist für die Erfindung nicht wesentlich, es geht hier lediglich darum, den abgepressten Stapel 5' sicher zu einer nachfolgenden Weiterverarbeitung abtransportieren zu können.The device 1 also has a pressing device 29 with a first pressing carriage 15 and a second pressing carriage 16. The two pressing carriages 15 and 16 are movable both in and against the stack conveying direction 13. Between the two pressing carriages 15 and 16, a stack 5 formed in the manner described above can be pressed in a subsequent method step, ie essentially the compressed air cushion located between the individual printing sheets 6 and the stack 5 thus compressed. To the side facing away from the conveyor 4 stacking side 38 is to said first end plate 10 and to the conveyor 4 facing stacking side 39, a second end plate 11th created, which consist for example of wood. The arrows 32 shown on the right side of FIG. 1 indicate the directions of the forces with which a previously formed stack 5 is pressed into a stack 5 '. A strapping device 12 arranged in this region of the device 1 and known to the person skilled in the art serves for strapping the pressed-out stack 5 '. The way in which the stack 5 'is strapped and thus stabilized is not essential to the invention; it is merely a question of being able to transport the pressed-out stack 5' safely to a subsequent further processing.

Bei dem in Figur 2 gezeigten Verfahrensschritt wird der abgepresste und umreifte Stapel 5' gemäss Pfeil 14 gerade zur Weiterverarbeitung abtransportiert. Der dadurch freigewordene erste Presswagen 15 wurde in Figur 2 bereits nach links zu dem sich bildenden Stapel 5 verfahren, während der zweite Presswagen 16 in seiner Position am rechten Ende der Vorrichtung 1 noch durch den abgepressten und umreiften Stapel 5' blockiert ist . Die Stützfunktion des Stapels 5 wird in dieser Situation noch vom zweiten Stütz- und Trennelement 9 wahrgenommen, welches die erste Endplatte 10 gegen den Stapel 5 drückt. Das erste Stütz- und Trennelement 8 wurde bereits nach unten bewegt und ist somit nicht mehr im Eingriff mit dem sich bildenden Stapel 5. Anschliessend durchgreift der in Richtung des sich bildenden Stapels 5 bewegte erste Presswagen 15 das zweite, beispielsweise gabelförmig ausgebildete Stütz- und Trennelement 9 und übernimmt damit die Abstützung des Stapels 5 an der Stapelseite 38. Dazu besitzt das zweite Stütz- und Trennelement 9 beispielsweise hier nicht gezeigte Schlitze, welche vom ersten Presswagen 15 durchgriffen werden können.At the in FIG. 2 shown process step, the pressed and strapped stack 5 'according to arrow 14 just transported away for further processing. The thus released first compacting carriage 15 was in FIG. 2 already moved to the left to the forming stack 5, while the second press carriage 16 is still blocked in its position at the right end of the device 1 by the pressed and strapped stack 5 '. The support function of the stack 5 is still perceived in this situation by the second support and separating element 9, which presses the first end plate 10 against the stack 5. The first supporting and separating element 8 has already been moved downwards and is therefore no longer in engagement with the forming stack 5. Subsequently, the first pressing carriage 15, which moves in the direction of the forming stack 5, passes through the second, for example, fork-shaped supporting and separating element 9 and thus takes over the support of the stack 5 on the stack side 38. For this purpose, the second support and separating element 9, for example, not shown here slots, which can be penetrated by the first press carriage 15.

Da der Stapel 5 nun vom ersten Presswagen 15 gestützt wird, ist das zweite Stütz- und Trennelement 9 ebenfalls frei. Es wird daher zunächst nach unten sowie nach links verfahren und gelangt gemeinsam mit dem ersten Stütz- und Trennelement 8 in die in Figur 3 gezeigte Stellung. Hierbei fahren die beiden Stütz- und Trennelemente 8 und 9 von unten in den Stapel 5 und trennen dadurch einen nachfolgenden, sich ausbildenden Stapel 5" vom Stapel 5 ab. Dieses Abtrennen eines Stapels 5" ist dem Fachmann an sich bekannt. Zum Stand der Technik wird hierzu beispielsweise auf die EP-A-0 623 542 , EP-A-0 847 949 und EP-A-0 872 443 verwiesen.Since the stack 5 is now supported by the first press carriage 15, the second supporting and separating element 9 is also free. It is therefore first moved down and to the left and passes together with the first support and separating element 8 in the FIG. 3 shown position. Here, the two supporting and separating elements 8 and 9 drive from below into the stack 5 and thereby separate a subsequent, forming stack 5 "from the stack 5. This separation of a stack 5" is the Skilled in the art. For example, the prior art is on the EP-A-0 623 542 . EP-A-0 847 949 and EP-A-0 872 443 directed.

Der nach dem Abtransport des abgepressten und umreiften Stapels 5' ebenfalls freigewordene zweite Presswagen 16 fährt nun ebenfalls nach links und übernimmt schliesslich die Stützfunktion des ersten Presswagens 15. Dies ist in Figur 3 gezeigt. Die beiden Stütz- und Trennelemente 8 und 9 fahren daraufhin entsprechend Fig. 4 auseinander, so dass sich der Stapel 5" weiter bilden kann. Das zweite Trennelement 9 und der zweite Presswagen 16 fahren anschliessend nach rechts in die in Figur 5 gezeigte Stellung, wobei das zweite Trennelement 9 durch den im Wesentlichen nicht bewegten, ersten Presswagen 15 hindurchgeführt wird. Hat der dabei mitgeführte Stapel 5 die in Figur 5 gezeigte Stellung erreicht, wird der erste Presswagen 15 herangefahren und übernimmt nun die Stützfunktion des zweiten Stütz- und Trennelementes 9 an der der Fördervorrichtung 4 zugewendeten Stapelseite 39. Das zweite Stütz- und Trennelement 9 der Stützvorrichtung 7 wird dadurch frei und in die in Figur 6 gezeigte untere Stellung gefahren. Die beiden Presswagen 15 und 16 pressen den Stapel 5 ab und fahren ihn in die in Figur 7 gezeigte Stellung, in der er umreift wird. Gleichzeitig wird das zweite Trennelement 9 wieder in die in Figur 1 gezeigte Stellung verfahren. Der geschilderte Verfahrensablauf kann nun mit dem nachfolgenden Stapel 5" wiederholt werden.The after the transport of the pressed and strapped stack 5 'also freed second press carriage 16 now also moves to the left and finally takes over the support function of the first press carriage 15. This is in FIG. 3 shown. The two support and separating elements 8 and 9 then drive accordingly Fig. 4 apart, so that the stack 5 "can continue to form.The second separating element 9 and the second pressing carriage 16 then move to the right in the in FIG. 5 shown position, wherein the second separating element 9 is passed through the substantially non-moving, first pressing carriage 15. Has the entrained stack 5 in the FIG. 5 reached position shown, the first press carriage 15 is moved up and now takes over the support function of the second support and separating element 9 on the conveyor 4 facing stacking side 39. The second supporting and separating element 9 of the support device 7 is thereby free and in the in FIG. 6 Lower position shown driven. The two press carriages 15 and 16 press the stack 5 and drive it into the in FIG. 7 shown position in which he is strapped. At the same time the second separating element 9 is again in the in FIG. 1 shown position. The described procedure can now be repeated with the subsequent stack 5 ".

Zum einfacheren Verständnis sind die Verfahrensabläufe in den Figuren 8 bis 18 in Draufsicht auf Teile der Vorrichtung 1 gezeigt. Vom ersten Presswagen 15 sind in Figur 8 lediglich zwei im Abstand zu einander angeordnete Pressorgane 18 gezeigt, die im Wesentlichen gleich ausgebildet sein können und sich in Stapelförderrichtung 13 erstrecken. Jedes Pressorgan 18 besitzt eine Pressbacke 21(Fig. 19, 20), an der ein bewegliches Stützelement 30 angeordnet ist.For easier understanding, the procedures in the FIGS. 8 to 18 shown in plan view of parts of the device 1. From the first press carriage 15 are in FIG. 8 only two spaced apart pressing members 18 are shown, which may be formed substantially the same and extending in the stack conveying direction 13. Each pressing member 18 has a pressing jaw 21 (FIG. Fig. 19, 20 ), on which a movable support member 30 is arranged.

In der Figur 9 wird der sich bildende Stapel 5 vom ersten Stütz- und Trennelement 8 abgestützt. Danach wird die erste Endplatte 10 mit dem hier nicht gezeigten zweiten Stütz- und Trennelement 9 gegen den Stapel 5 verfahren, so dass das erste Stütz- und Trennelement 8 entfernt werden kann. Die Figur 10 zeigt die Vorrichtung 1 in einem anschliessenden Verfahrensschritt, in dem der Stapel 5 an der von der Fördervorrichtung 4 abgewendeten Stapelseite 38 vom ersten Presswagen 15 abgestützt ist. Dazu sind die beiden Stützelemente 30 jeweils an die erste Endplatte 10 angelegt. Der Stapel 5 befindet sich hierbei teilweise in einem Zwischenraum 33 zwischen den beiden Pressorganen 18.In the FIG. 9 the forming stack 5 is supported by the first supporting and separating element 8. Thereafter, the first end plate 10 is moved with the second supporting and separating element 9, not shown here, against the stack 5, so that the first supporting and separating element 8 can be removed. The FIG. 10 shows the device 1 in a subsequent method step in which the stack 5 is supported on the stack side 38 away from the conveyor device 4 by the first compacting carriage 15. For this purpose, the two support elements 30 are respectively applied to the first end plate 10. The stack 5 is here partly in a gap 33 between the two pressing members 18th

Die Figur 11 zeigt die Bewegung des zweiten Presswagens 16 hin zum Stapel 5. Der zweite Presswagen 16 fährt mit zwei Backen 34 in den Zwischenraum 33 der beiden Pressorgane 18 in die in Figur 12 gezeigte Stellung. Die beiden Backen 34 liegen nun mit einem vorderen Ende an der ersten Endplatte 10 an und stützen diese ab, wodurch der Stapel 5 an der Stapelseite 38 nunmehr durch den zweiten Presswagen 16 abgestützt wird. Daraufhin werden die beiden Pressorgane 18 des ersten Presswagens 15 quer zur Stapelförderrichtung 13 auseinander gefahren. Gleichzeitig werden die beiden Stützelemente 30 in ihre in Figur 13 gezeigte zurückgezogene Stellung bewegt. Die Bewegung kann eine Schwenkbewegung, eine Schiebebewegung oder eine sonstige Bewegung sein. Wie ersichtlich schränken die Stützelemente 30 den Zwischenraum 33 zwischen den Pressorganen 18 in dieser zurückgezogenen Stellung nicht ein. Der Zwischenraum 33 ist damit für den in Förderrichtung 13 erfolgenden Durchgang des Stapels 5 frei, wobei der Stapel 5 dabei auch wesentlich breiter sein könnte, als in Figur 13 gezeigt.The FIG. 11 shows the movement of the second press carriage 16 towards the stack 5. The second press carriage 16 moves with two jaws 34 in the intermediate space 33 of the two pressing members 18 in the FIG. 12 shown position. The two jaws 34 now abut against the first end plate 10 with a front end and support it, whereby the stack 5 on the stack side 38 is now supported by the second pressing carriage 16. Then the two pressing members 18 of the first press carriage 15 are moved apart transversely to the stack conveying direction 13. At the same time, the two support members 30 in their in FIG. 13 shown retracted position moves. The movement may be a pivoting movement, a sliding movement or some other movement. As can be seen, the support members 30 do not restrict the gap 33 between the pressing members 18 in this retracted position. The gap 33 is thus free for the passage of the stack 5 in the conveying direction 13, wherein the stack 5 could also be substantially wider than in FIG FIG. 13 shown.

Die Figuren 14 und 15 zeigen die Bewegung des bereits zuvor durch die Stütz- und Trennelemente 8, 9 vom Stapel 5" abgetrennten Stapels 5 in Stapelförderrichtung 13, d.h. in Richtung der Umreifvorrichtung 12. Der Stapel 5 wird dabei an der Stapelseite 39 vom zweiten Stütz- und Trennelement 9 und an der Stapelseite 38 vom zweiten Presswagen 16 abgestützt. Das Stütz- und Trennelement 8 stützt den sich bildenden Stapel 5" ab. Die Figuren 16 und 17 zeigen die anschliessende Bewegung des ersten Presswagens 15 in eine Stützposition, in welcher dieser an der Stapelseite 39 anliegt, so dass das zweite Stütz- und Trennelement 9 nach unten weg bewegt werden kann. Die der Figur 7 entsprechende Figur 18 zeigt schliesslich den Stapel 5 im Bereich der Umreifvorrichtung 12.The FIGS. 14 and 15 show the movement of the previously separated by the supporting and separating elements 8, 9 from the stack 5 "stack 5 in the stack conveying direction 13, ie in the direction of the strapping 12. The stack 5 is doing on the stack side 39 of the second support and separating element 9 and is supported on the stacking side 38 by the second pressing carriage 16. The supporting and separating element 8 supports the forming stack 5 ". The FIGS. 16 and 17 show the subsequent movement of the first press carriage 15 in a supporting position in which this rests on the stack side 39, so that the second supporting and separating element 9 can be moved downwards away. The the FIG. 7 appropriate FIG. 18 finally shows the stack 5 in the region of the strapping device 12.

Anhand der Figuren 19 bis 22 wird nachfolgend der erste Presswagen 15 näher erläutert.Based on FIGS. 19 to 22 Below, the first press carriage 15 is explained in detail.

Der erste Presswagen 15 besitzt ein Gestell 17, an dem vier Führungsrollen 19 befestigt sind, an denen der erste Presswagen 15 an hier nicht gezeigten Schienen verfahrbar ist. Weiter ist am Gestell 17 eine sich quer erstreckende Achse 26 befestigt, an welcher die beiden Pressorgane 18 mit jeweils einem Lager 27 verschiebbar gelagert sind. Die Pressorgane 18 können jeweils mit einem Motor 23 und einem endlosen Antriebsorgan 31 zur Veränderung ihres in Figur 19 gezeigten Abstandes 35 auf der Achse 26 verschoben werden. Der Abstand 35 zwischen den Pressorganen 18 kann somit verkleinert oder vergrössert werden. Dadurch ist eine Anpassung an unterschiedliche Stapelbreiten möglich, so dass beispielsweise auch sehr schmale oder sehr breite Stapel verarbeitet werden können. Breite Stapel 5 sind beispielsweise solche aus Doppelnutzen.The first press carriage 15 has a frame 17 to which four guide rollers 19 are fastened, on which the first press carriage 15 can be moved on rails, not shown here. Next, a transversely extending axis 26 is fixed to the frame 17, on which the two pressing members 18 are mounted, each with a bearing 27 slidably. The pressing members 18 may each with a motor 23 and an endless drive member 31 for changing their in FIG. 19 shown distance 35 are moved on the axis 26. The distance 35 between the pressing members 18 can thus be reduced or increased. As a result, an adaptation to different stack widths is possible, so that, for example, very narrow or very wide stack can be processed. Width stack 5 are, for example, those from double benefits.

Am Gestell 17 ist ein weiterer Motor 22 befestigt (Figur 21), der dazu dient, beim Abpressen eines Stapels 5 die erforderliche Presskraft aufzubringen. Der Motor 22 wirkt hierbei über zwei Zahnräder 37 (Figur 19) auf hier nicht gezeigte Zahnstangen. Selbstverständlich ist auch eine andere Kraftübertragung denkbar. Kabel 20 dienen der elektrischen Versorgung des Motors 22. Weiterhin sind nicht dargestellte pneumatische und elektrische Anschlüsse und solche für eine hier nicht gezeigte Steuervorrichtung vorgesehen.On the frame 17, another motor 22 is attached ( FIG. 21 ), which serves to apply the required pressing force when pressing a stack 5. The motor 22 acts via two gears 37 ( FIG. 19 ) on racks, not shown here. Of course, another power transmission is conceivable. Cables 20 are used to provide electrical power to the motor 22. Furthermore, not shown pneumatic and electrical connections and such are provided for a control device not shown here.

An den beiden Pressorganen 18 ist jeweils ein Stützelement 30 angeordnet, das vorzugsweise stab- oder bügelförmig ausgebildet ist. Die Stützelemente 30 sind jeweils an einem oberen Ende über ein Gestänge 28 (Figur 22) schwenkbar an einer Pressbacke 21 gelagert. Jedes Stützelement 30 ist über das Gestänge 28 mit einem pneumatischen Stellzylinder 25 verbunden, der an der entsprechenden Pressbacke 21 befestigt ist. Durch Betätigen der Stellzylinder 25 können die Stützelemente 30 zwischen einer in den Figuren 19, 21 und 23 gezeigten zurückgezogenen, äusseren Stellung und einer in den Figuren 20, 22 und 24 gezeigten aktiven, inneren Stellung bewegt werden. In der aktiven Stellung ragen die Stützelemente in den Zwischenraum 33 zwischen den beiden Pressbacken 21 hinein. Die mittels der Stellzylinder 25 erfolgende Bewegung der Stützelemente 30 wird über die hier nicht gezeigte Steuervorrichtung gesteuert. In der zurückgezogenen Stellung sind die Stützelemente 30 hinter den Pressbacken 21 angeordnet, so dass sie den Zwischenraum 33 nicht beengen und die maximale Breite für den Durchgang des Stapels 5 zur Verfügung steht. Auch vergleichsweise breite Stapel 5 können ohne Kollisionsgefahr durch den ersten Presswagen 15 hindurchgeführt werden. Wie insbesondere die Figur 24 erkennen lässt, befinden sich die Stützelemente 30 an einer der Fördervorrichtung 4 zugewendeten Seite 36 der Pressbacken 21 und damit des ersten Presswagens 15. Die Rückseite 24 der Pressbacken 21 bildet eine Fläche, an welcher ein Stapel 5 abgepresst wird.At the two pressing members 18 each have a support member 30 is arranged, which is preferably rod-shaped or bow-shaped. The support elements 30 are each at an upper end via a linkage 28 (FIG. FIG. 22 ) pivotally mounted on a pressing jaw 21. Each support member 30 is connected via the linkage 28 with a pneumatic actuating cylinder 25 which is fixed to the corresponding pressing jaw 21. By pressing the actuating cylinder 25, the support members 30 between a in the Figures 19 . 21 and 23 shown withdrawn, outer position and one in the Figures 20 . 22 and 24 shown active, inner position to be moved. In the active position, the support elements protrude into the gap 33 between the two pressing jaws 21 into it. The taking place by means of the actuating cylinder 25 movement of the support members 30 is controlled by the control device, not shown here. In the retracted position, the support elements 30 are arranged behind the pressing jaws 21, so that they do not restrict the gap 33 and the maximum width for the passage of the stack 5 is available. Also comparatively wide stack 5 can be passed through the first press carriage 15 without collision. How the particular FIG. 24 can recognize, the support members 30 are located on one of the conveyor 4 facing side 36 of the pressing jaws 21 and thus the first press carriage 15. The back 24 of the pressing jaws 21 forms a surface on which a stack 5 is pressed.

Die Stützelemente 30 sind hier nach unten gerichtete stabförmige Bügel. Sie können jedoch auch plattenförmig ausgebildet und seitlich verschiebbar gelagert sein. Grundsätzlich können die Stützelemente 30 auch als nicht bewegbare Flächen der der Fördervorrichtung 4 zugewendeten Seite 36 der Pressbacken 21 ausgebildet sein. Wesentlich ist eine solche Ausbildung der Stützelemente 30, mit der sie bei einem sich bildenden Stapel 5, 5" solange eine Stützfunktion übernehmen können, bis hierzu der zweite Presswagen 16 zur Verfügung steht. Damit kann der erste Presswagen 25, ausser der bisher üblichen Pressfunktion, vorteilhaft auch eine Stützfunktion übernehmen. Die Stützelemente 30 können mit einem vergleichsweise kleinen konstruktiven Aufwand realisiert werden, so dass sich keine wesentlich höheren Herstellungskosten ergeben. Trotzdem kann die Zykluszeit wesentlich vermindert werden.The support members 30 are here downwardly directed rod-shaped bracket. However, they can also be plate-shaped and mounted laterally displaceable. In principle, the support elements 30 can also be designed as non-movable surfaces of the conveyor device 4 facing side 36 of the pressing jaws 21. Essential is such a design of the support elements 30, with which they can take over a support function in a stack forming 5, 5 "as long as the second pressing carriage 16 is available. The support elements 30 can be realized with a comparatively small design effort, so that there are no significantly higher production costs, nevertheless the cycle time can be substantially reduced.

Da der zweite Presswagen 16 nach dem Abpressen und ggf. Umreifen eines Stapels unabhängig von dessen Länge zwangsläufig auf den erfolgten Abtransport warten muss, bevor er zur Abstützung des sich ausbildenden neuen Stapels entgegen der Stapelförderrichtung 13 verfahren werden kann, ist die mit der erfindungsgemässen Vorrichtung erreichbare Zeiteinsparung bzw. die Erhöhung der Leistung bei vergleichsweise kurzen Stapeln 5 besonders gross.Since the second press carriage 16 after pressing and possibly strapping a stack, regardless of its length inevitably has to wait for the successful removal before it can be moved to support the forming new stack against the Stapelförderrichtung 13, which is achievable with the inventive device Time savings or the increase in performance with comparatively short stacks 5 particularly large.
