Bei der Buchproduktion werden die noch nicht mit einer Buchdecke versehenen Buchblocks mittels einer Transporteinrichtung gefördert, während eine mit einer Schöpfwalze zusammenwirkende Auftragswalze jeweils am Rücken der Buchblocks abgewälzt wird und dabei Klebstoff aufträgt. Der am Rücken des Buchblocks aufgetragene Klebstoff dient in einem nachfolgenden Arbeitsschritt zur Verbindung des Buchblocks mit der Buchdecke. Die Kontur des Rückens kann dabei sowohl gerade als auch rund sein, weshalb jeweils eine entsprechend ausgebildete Auftragswalze Verwendung findet. Bekannte Auftragswalzen sind dementsprechend beispielsweise flach oder profiliert ausgebildet.In book production, the book block not yet provided with a book cover are conveyed by means of a transport device, while a cooperating with a scoop roller applicator roll is in each case rolled on the back of the book block, while applying adhesive. The applied on the back of the book block adhesive is used in a subsequent step to connect the book block with the book cover. The contour of the back can be both straight and round, which is why in each case a suitably trained application roller is used. Known applicator rollers are accordingly formed, for example, flat or profiled.

Weil die den Klebstoff auf den Rücken des Buchblocks aufbringende Auftragswalze jeweils auf ein bestimmtes Format von Buchblocks ausgelegt ist, muss diese bei einem Formatwechsel gegen eine dem neuen Format entsprechende Auftragswalze ausgewechselt werden.A new production order usually results in a change in the format of the books to be produced in book production. Because the applicator roll applying the adhesive to the back of the book block has a specific format book block is designed, it must be replaced in a format change against a corresponding to the new format application roller.

Liegt ein neuer Fertigungsauftrag mit einem vom bisherigen abweichenden Buchformat vor, muss die Buchfertigungsstraße aus sicherheitstechnischen Gründen zunächst angehalten werden, da das Auswechseln, d.h. ein Ausbau bzw. Einbau der Auftragswalze nur bei geöffneter Verschalung durchgeführt werden kann. Demnach erfolgt nach dem Auftragen des Klebstoffs auf den Rücken des letzten zum vorhergehenden Fertigungsauftrag gehörenden Buchblocks zunächst ein Maschinenhalt. Nach dem Öffnen der Verschalung wird die bisherige Auftragswalze ausgebaut und eine dem neuen Fertigungsauftrag entsprechende Auftragswalze montiert. Bei den zu diesem Zweck bekannten Verfahren wird die Auftragswalze stets manuell ausgewechselt.If there is a new production order with a book format deviating from the previous one, the book production line must first be stopped for safety reasons, since the replacement, i. removal or installation of the applicator roll can only be carried out with the shuttering open. Accordingly, after the application of the adhesive to the back of the last book block belonging to the preceding production order, a machine stop is first carried out. After opening the shuttering, the previous application roller is removed and mounted on the new production order application roller. In the method known for this purpose, the applicator roll is always replaced manually.

Bei einem ersten bekannten Verfahren wird dazu die Auftragswalze zunächst mittels einer manuell bedienten Stellspindel von der Schöpfwalze weggeschwenkt und danach von Hand entnommen, d.h. axial von ihrer Antriebswelle heruntergeschoben sowie abtransportiert. Anschließend wird eine neue Auftragswalze axial auf die Antriebswelle geschoben, dort arretiert und mittels der manuell bedienten Stellspindel an die Schöpfwalze herangeführt. Nach dem Schließen der Verschalung kann die Produktion wieder aufgenommen und der neue Fertigungsauftrag abgearbeitet werden.In a first known method for this purpose, the applicator roll is first pivoted away from the scoop roller by means of a manually operated adjusting spindle and then removed by hand, i. axially pushed down from its drive shaft and transported away. Subsequently, a new application roller is pushed axially onto the drive shaft, locked there and introduced by means of the manually operated adjusting spindle to the scoop roller. After closing the casing, production can be resumed and the new production order processed.

Gemäss eines zweiten bekannten Verfahrens wird die auszutauschende Auftragswalze mittels einer exzentrisch gelagerten Antriebswelle manuell ausser Eingriff mit der Schöpfwalze gebracht und schliesslich die neue Auftragswalze an die Schöpfwalze herangeführt. Nachdem die Exzenterlagerung fixiert und die Verschalung wieder geschlossen worden ist, kann die Produktion wieder aufgenommen und der neue Fertigungsauftrag abgearbeitet werden.According to a second known method, the applicator roller to be exchanged is manually disengaged from the scoop roller by means of an eccentrically mounted drive shaft, and finally the new applicator roller is brought to the scoop roller. Once the eccentric bearing has been fixed and the casing has been closed again, production can be resumed and the new production order can be processed.

Bei den bekannten Verfahren und mit den bekannten Vorrichtungen zum Auswechseln einer Auftragswalze wird das Weg- und das Heranführen der Auftragswalze von der bzw. an die Schöpfwalze manuell durchgeführt. Dabei muss die in der Maschine befindliche, auszuwechselnde Auftragswalze zunächst zumindest so weit von der Schöpfwalze weggeführt werden, dass beim anschliessenden in axialer Richtung erfolgenden Herunterschieben der Auftragswalze von der Antriebswelle deren grösster Aussendurchmesser die Schöpfwalze nicht berührt. Dies gilt ebenso für die neu in die Maschine einzuführenden und dazu in axialer Richtung auf die Antriebswelle aufzuschiebende Auftragswalze. Nachdem die neue Auftragswalze zugeführt worden ist, muss deren Oberfläche wieder in Kontakt mit der Schöpfwalze gebracht werden, d.h. der Achsabstand der neuen Auftragswalze zur Schöpfwalze und insbesondere der Anpressdruck der beiden Walzen muss korrekt eingestellt werden. Dies bedeutet einerseits, dass der Anpressdruck gross genug sein muss, damit die Übertragung des Klebstoffs von der Oberfläche der Schöpfwalze auf die Oberfläche der Auftragswalze sichergestellt ist. Andererseits darf der Anpressdruck nicht zu gross sein, da sonst ein unnötig hoher Verschleiss der Auftragswalze auftritt. Weil das Wegführen bzw. das Heranführen der Auftragswalze von der bzw. an die Schöpfwalze manuell gesteuert ist und damit sowohl deren tatsächlicher Achsabstand als auch der Anpressdruck vom Gefühl des Maschinenführers abhängen, ist eine exakte Reproduzierbarkeit des Verfahren nicht gegeben und ein erhöhter Verschleiß der Auftragswalze nicht auszuschließen. Zudem ist die manuelle Steuerung des gesamten Auswechselvorgangs relativ zeitaufwändig, so dass sich insbesondere bei der Herstellung kleinerer Auflagen ein relativ hoher Anteil an Umrüstzeit ergibt.In the known methods and with the known devices for replacing an applicator roll the way and bringing the applicator roll of performed manually or to the scoop roller. In this case, the in-machine, to be replaced applicator roll must first be at least as far away from the scoop roller that does not touch the scoop roller in the subsequent taking place in the axial direction pushing down the applicator roll from the drive shaft whose largest outer diameter. This also applies to the newly introduced into the machine and in the axial direction aufzuschiebende on the drive shaft applicator roll. After the new application roller has been supplied, the surface must be brought back into contact with the scoop roller, ie the center distance of the new applicator roller to the scoop roller and in particular the contact pressure of the two rollers must be adjusted correctly. On the one hand, this means that the contact pressure must be high enough to ensure the transfer of the adhesive from the surface of the scoop roller to the surface of the applicator roll. On the other hand, the contact pressure must not be too large, otherwise an unnecessarily high wear of the applicator roll occurs. Because the removal or bringing the applicator roll from the or on the scoop roller is controlled manually and thus depend both their actual center distance and the contact pressure on the feeling of the machine operator, an exact reproducibility of the process is not given and increased wear of the applicator roll excluded. In addition, the manual control of the entire replacement process is relatively time-consuming, so that results in a relatively high proportion of changeover time, especially in the production of smaller runs.

Aufgabe der Erfindung ist es daher, ein Verfahren und eine Vorrichtung zum Auswechseln einer Klebstoff-Auftragswalze bereitzustellen, die ein schnelleres, sicheres und exakt reproduzierbares Auswechseln der Auftragswalze ermöglichen und dabei einen erhöhten Verschleiß der Auftragswalze weitgehend ausschliessen.The object of the invention is therefore to provide a method and apparatus for replacing an adhesive applicator roll, which allow a faster, safe and exactly reproducible replacement of the applicator roll and thereby largely preclude increased wear of the applicator roll.

Erfindungsgemäss wird diese Aufgabe durch ein Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 1 sowie durch eine Vorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 6 und durch eine Buchfertigungsstraße nach Anspruch 13 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen angegeben.According to the invention, this object is achieved by a method having the characterizing features of claim 1 and by a device having the characterizing features of claim 6 and by a book production line according to claim 13. Advantageous embodiments are specified in the subclaims.

Erfindungsgemäß weist die Vorrichtung eine mit der Antriebswelle der Auftragswalzen verbundene Stelleinrichtung mit zwei zusammenwirkenden, mit einer Maschinensteuerung der Vorrichtung wirkverbundenen Stellelementen auf. Dabei ist die Antriebswelle der Auftragswalzen mit dem ersten Stellelement zur Schöpfwalze schwenkbar ausgebildet. Mit dem zweiten Stellelement ist sowohl ein Achsabstand als auch ein Anpressdruck zwischen der Antriebswelle der Auftragswalzen und der Schöpfwalze einstellbar. Beim Betrieb der Vorrichtung wird zunächst die erste Auftragswalze mittels des ersten Stellelements der Stelleinrichtung von der Schöpfwalze weggeschwenkt. Danach werden mittels des zweiten Stellelements der Stelleinrichtung ein Achsabstand und ein Anpressdruck zwischen der Rotationsachse der Antriebswelle der Auftragswalzen und der Rotationsachse der Schöpfwalze voreingestellt. Anschließend wird die zweite Auftragswalze mittels des ersten Stellelements an die Schöpfwalze herangeschwenkt. Dazu werden das erste und das zweite Stellelement durch die Maschinensteuerung entsprechend angesteuert.According to the invention, the device comprises a control device connected to the drive shaft of the applicator rollers with two interacting, with a machine control of the device operatively connected actuators. In this case, the drive shaft of the applicator rollers with the first adjusting element to the scoop roller is designed to be pivotable. With the second actuator, both an axial distance and a contact pressure between the drive shaft of the applicator rollers and the scoop roller is adjustable. During operation of the device, the first application roller is first pivoted away from the scoop roller by means of the first control element of the control device. Thereafter, an axial distance and a contact pressure between the axis of rotation of the drive shaft of the applicator rollers and the axis of rotation of the scoop roller are preset by means of the second adjusting element of the adjusting device. Subsequently, the second application roller is pivoted by means of the first control element to the scoop roller. For this purpose, the first and the second actuator are controlled accordingly by the machine control.

Aufgrund dieser Ausbildung der Vorrichtung und des entsprechenden Verfahrensablaufs kann das Auswechseln der Auftragswalze sicher und exakt reproduzierbar durchgeführt und ein erhöhter Verschleiß der Auftragswalze weitgehend ausgeschlossen werden. Dabei wird das Wegschwenken und das Heranschwenken der jeweiligen Auftragswalze automatisiert, so dass der Zeitaufwand zum Auswechseln einer Auftragswalze deutlich gesenkt und manuelle Fehleinstellungen minimiert werden können.Due to this design of the device and the corresponding procedure, the replacement of the applicator roll can be performed safely and accurately reproducible and increased wear of the applicator roll are largely excluded. In this case, the pivoting away and pivoting of the respective applicator roll is automated, so that the time required to replace an applicator roll significantly reduced and manual misadjustments can be minimized.

Gemäss einer Ausführungsform des erfindungsgemäßen Verfahrens werden die beiden Stellelemente der Stelleinrichtung über die Maschinensteuerung gemeinsam angesteuert. Auf diese Weise kann das Verfahren vorteilhaft relativ einfach betrieben werden.According to one embodiment of the method according to the invention, the two adjusting elements of the adjusting device are jointly controlled via the machine control. In this way, the method can advantageously be operated relatively easily.

Eine weitere Ausführungsform des erfindungsgemäßen Verfahrens sieht vor, dass das erste Stellelement pneumatisch beaufschlagt und das zweite Stellelement motorisch angetrieben wird. Damit kann einerseits eine schnelle Schwenkbewegung für den Auswechselvorgang der jeweiligen Auftragswalze und andererseits eine präzise Einstellung des Achsabstands und des Anpressdrucks zwischen der zweiten Auftragswalze und der Schöpfwalze realisiert werden.A further embodiment of the method according to the invention provides that the first actuating element is acted upon pneumatically and the second actuating element is driven by a motor. This can on the one hand a quick pivoting movement for the replacement process of the respective applicator roll and on the other hand a precise Setting the center distance and the contact pressure between the second applicator roll and the scoop roller can be realized.

Gemäss einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens wird das erste Stellelement auch nach dem Heranschwenken der zweiten Auftragswalze an die Schöpfwalze pneumatisch beaufschlagt und damit die Auftragswalze federnd gegen die Schöpfwalze angepresst. Das erste Stellelement der Vorrichtung ist dementsprechend auch nach dem Heranschwenken der zweiten Auftragswalze an die Schöpfwalze pneumatisch beaufschlagbar und die zweite Auftragswalze federnd gegen die Schöpfwalze anpressbar ausgebildet. Damit dient das zum Schwenken der jeweiligen Auftragswalze verwendete erste Stellelement nicht nur zum Auswechseln der Auftragswalze, sondern kann während des Auftragens von Klebstoff auf den Rücken eines Buchblocks vorteilhaft auch als pneumatische Feder genutzt werden, welche den Anpressdruck zwischen der Auftragswalze und der Schöpfwalze aufrecht erhält und daher einen konstanten Klebstofffilm garantiert.According to a further embodiment of the method according to the invention, the first actuating element is pneumatically acted upon after the pivoting of the second application roller to the scoop roller and thus the applicator roller is resiliently pressed against the scoop roller. The first actuator of the device is accordingly pneumatically acted upon after the pivoting of the second applicator roll to the scoop roller and the second applicator roll formed resiliently against the scoop roller. Thus, the first actuator used for pivoting the respective applicator roll not only serves to replace the applicator roll, but can also be advantageously used as a pneumatic spring during the application of adhesive to the back of a book block, which maintains the contact pressure between the applicator roll and the scoop roller and therefore guarantees a constant adhesive film.

Gemäss einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens wird die Auftragswalze während des Auftragens des Klebstoffs auf einen vom vorherigen Buchblock in seiner Höhenlage abweichenden, nachfolgenden Buchblock unter Beibehaltung sowohl des Achsabstands als auch des Anpressdrucks zur Schöpfwalze der Abweichung entsprechend in ihrer Höhenlage angepasst. Indem die Auftragswalze somit nach oben ausweicht, kann der Klebstoff in gleicher Qualität vorteilhaft auch auf Buchblocks aufgetragen werden, deren Rücken die Auftragswalze nicht in der genau gleichen horizontalen Ebene passieren.According to a further embodiment of the method according to the invention, the applicator roll is adjusted during the application of the adhesive to a deviating from the previous book block in height, subsequent book block while maintaining both the axial distance and the contact pressure to the scoop roller of the deviation according to their altitude. By thus avoiding the applicator roll upward, the adhesive of the same quality can advantageously also be applied to book blocks whose backs do not pass the applicator roll in the exact same horizontal plane.

Gemäß einer Ausführungsform der erfindungsgemäßen Vorrichtung ist die Antriebswelle der Auftragswalzen dazu auf einer Kreisbahn um die Rotationsachse der Schöpfwalze schwenkbar ausgebildet. Damit kann auch bei aufeinander folgenden Buchblocks, deren Rücken die Auftragswalze nicht in der genau gleichen horizontalen Ebene passieren, ein konstanter Leimspalt aufrecht erhalten und somit die Leimversorgung der Auftragswalze auch bei die Auftragswalze in unterschiedlicher Höhenlage passierenden Buchblocks sichergestellt werden.According to one embodiment of the device according to the invention, the drive shaft of the applicator rollers is designed to pivot on a circular path about the rotation axis of the scoop roller. Thus, even with successive book block whose back the applicator roll does not happen in the exact same horizontal plane, maintained a constant glue gap and thus the glue supply of the applicator roll even at the applicator roller passing in different altitude book block be ensured.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung weisen das erste Stellelement eine erste und das zweite Stellelement eine zweite Längsachse auf, wobei die beiden Längsachsen in einer vertikalen Ebene durch die Förderrichtung einen variablen Stellwinkel einschließen. Dadurch kann das zweite Stellelement vorteilhaft gemeinsam mit der Auftragswalze geschwenkt werden.In accordance with a further embodiment of the device according to the invention, the first actuating element has a first and the second actuating element has a second longitudinal axis, the two longitudinal axes enclosing a variable setting angle in a vertical plane through the conveying direction. As a result, the second actuating element can advantageously be pivoted together with the application roller.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung weist diese einen Grundrahmen sowie ein Schwenkgestell mit einer Rotationsachse und mit zwei Schenkeln auf, wobei die Antriebswelle der Auftragswalzen im Schwenkgestell schwenkbar gelagert ist, und wobei ein erster Schenkel des Schwenkgestells mit dem ersten Stellelement und ein zweiter Schenkel des Schwenkgestells mit dem zweiten Stellelement verbunden ist. Derartige Hebelmechanismen sorgen für eine gute Reproduzierbarkeit bei automatisierten Abläufen.According to a further embodiment of the device according to the invention, this has a base frame and a pivoting frame with a rotation axis and two legs, wherein the drive shaft of the applicator rollers is pivotally mounted in the pivoting frame, and wherein a first leg of the pivoting frame with the first actuating element and a second leg of Swivel frame is connected to the second actuator. Such lever mechanisms ensure good reproducibility in automated processes.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung weist das zweite Stellelement ein abtriebsseitiges Ende auf, welches an einem schwenkbaren Hebel des Grundrahmen der Vorrichtung abstützbar ausgebildet ist. Damit kann die Schwenkbewegung der Antriebswelle der Auftragswalzen vorteilhaft begrenzt sowie ein Ausweichen der Auftragswalzen bei einem vorstehenden Buchrücken ermöglicht werden.According to a further embodiment of the device according to the invention, the second actuating element has an output-side end, which is designed to be supportable on a pivotable lever of the base frame of the device. Thus, the pivoting movement of the drive shaft of the applicator rollers can be advantageously limited and a dodging of the applicator rollers are made possible with a protruding spine.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung weist das erste Stellelement einen Pneumatikzylinder und das zweite Stellelement eine mit einem Stellantrieb wirkverbundene Spindel auf. Damit kann zusätzlich zum durch den Abstand von Auftragswalze und Schöpfwalze gegebenen Anpressdruck ein Anpressdruck für das Wegdrücken der Auftragswalze von der Schöpfwalze eingestellt werden.According to a further embodiment of the device according to the invention, the first actuating element has a pneumatic cylinder and the second actuating element has a spindle operatively connected to an actuator. Thus, in addition to the given by the distance of applicator roll and scoop roller contact pressure for the pushing away of the applicator roll can be adjusted by the scoop roller.

Die Figuren zeigen ein einziges Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung 1 zum Auswechseln einer zum Auftragen von Klebstoff auf den Rücken eines in einer Förderrichtung 8 transportierten Buchblocks dienenden, zu einer den Klebstoff aus einem Klebstoffbehälter 2 entnehmenden Schöpfwalze 5 fluchtend angeordneten (Fig. 1) und zum Auftragen des Klebstoffs am Rücken des Buchblocks abgewälzten Auftragswalze, bei dem eine im Eingriff mit der Schöpfwalze 5 befindliche, erste Auftragswalze 3.1 von der Schöpfwalze 5 weggeschwenkt, gegen eine zweite Auftragswalze 3.2 ausgewechselt und diese an die Schöpfwalze 5 herangeschwenkt wird, wobei sowohl die erste als auch die zweite Auftragswalze 3.1, 3.2 eine gemeinsame, quer zur Förderrichtung 8 des Buchblocks angeordnete Antriebswelle 4 aufweisen.The figures show a single exemplary embodiment of a device 1 according to the invention for exchanging a scoop roller 5 serving to apply adhesive to the back of a book block transported in a conveying direction 8, which is arranged in alignment with a scoop roller 5 which removes the adhesive from an adhesive container 2 ( Fig. 1 ) and applied to the application of the adhesive on the back of the book block rolled applicator roll, in which one located in engagement with the scoop roller 5, first applicator roll 3.1 pivoted away from the scoop roller 5, replaced with a second applicator roll 3.2 and this is pivoted to the scoop roller 5, both the first and the second application roller 3.1, 3.2 have a common, transverse to the conveying direction 8 of the book block arranged drive shaft 4.

Die Vorrichtung 1 weist einen Grundrahmen 6 (Fig. 2) auf, in den der Klebstoffbehälter 2 eingehängt ist. Im Grundrahmen 6 ist zudem die Schöpfwalze 5 gelagert, welche eine ebenfalls quer zur Förderrichtung 8 der Buchblocks angeordnete Rotationsachse 5a aufweist. Die auf der Antriebswelle 4 gelagerte erste Auftragswalze 3.1 ist in Förderrichtung 8 stromab der Schöpfwalze 5 angeordnet.The device 1 has a base frame 6 (FIG. Fig. 2 ), in which the adhesive container 2 is mounted. In the base frame 6, the scoop roller 5 is also stored, which a likewise arranged transversely to the conveying direction 8 of the book block rotation axis 5a. The first application roller 3.1 mounted on the drive shaft 4 is arranged downstream of the scoop roller 5 in the conveying direction 8.

Die Figuren 1 und 5 zeigen Frontansichten der Vorrichtung 1, wobei jeweils eine andere Auftragswalze 3.1, 3.2 mit der Schöpfwalze 5 fluchtend angeordnet ist. Dagegen sind in den Figuren 2, 3, 4 und 6 Schnittansichten durch Rotationsachsen von Bauteilen der Vorrichtung 1 dargestellt.The FIGS. 1 and 5 show front views of the device 1, wherein in each case another application roller 3.1, 3.2 is arranged in alignment with the scoop roller 5. In contrast, in the Figures 2 . 3 . 4 and 6 Sectional views represented by axes of rotation of components of the device 1.

Obwohl weder der Buchblock noch die Transporteinrichtung explizit gezeigt sind, ist den Figuren durch die Darstellung der Förderrichtung 8 und der Unterkante der jeweils für das Auftragen des Klebstoffs zuständigen Auftragswalze 3.1, 3.2 implizit sowohl eine Transporteinrichtung als auch die Position des Rückens des Buchblocks zu entnehmen.Although neither the book block nor the transport device are explicitly shown, the figures by the representation of the conveying direction 8 and the lower edge of each responsible for the application of adhesive applicator roller 3.1, 3.2 implicitly refer both a transport device and the position of the back of the book block.

Die beiden Auftragswalzen 3.1, 3.2 sind unterschiedlich ausgebildet, d.h. die erste Auftragswalze 3.1 weist eine profilierte Mantelfläche 7.1 auf, während die zweite Auftragswalze 3.2 mit einer glatten Mantelfläche 7.2 ausgestattet ist. Natürlich können je nach den zu bearbeitenden Buchblocks auch Auftragswalzen mit anders ausgebildeten Mantelflächen sowie Auftragswalzen gleicher oder auch unterschiedlicher Größe eingesetzt werden.The two applicator rollers 3.1, 3.2 are designed differently, i. the first application roller 3.1 has a profiled lateral surface 7.1, while the second application roller 3.2 is equipped with a smooth lateral surface 7.2. Of course, depending on the book block to be processed, applicator rollers with differently shaped lateral surfaces and applicator rollers of the same or different size can also be used.

Die Vorrichtung 1 weist ferner eine Stelleinrichtung 10 zum Heranschwenken bzw. zum Wegschwenken der jeweiligen Auftragswalze 3.1, 3.2 an die bzw. von der Schöpfwalze 5 auf. Die Stelleinrichtung 10 besitzt ein erstes Stellelement 17, welches einen im Wesentlichen unterhalb des Klebstoffbehälters 2 angeordneten und entlang der Förderrichtung 8 ausgerichteten Pneumatikzylinder 17a aufweist. Natürlich ist auch eine andere geeignete Ausbildung und Anordnung des ersten Stellelements 17 möglich, beispielsweise mittels eines nicht dargestellten, abgefederten Exzenters, mit dem die jeweilige Auftragswalze 3.1, 3.2 an die Schöpfwalze 5 herangeführt bzw. von der Schöpfwalze 5 weggeführt wird.The device 1 further comprises an adjusting device 10 for pivoting or for pivoting away the respective applicator roller 3.1, 3.2 to or from the scoop roller 5. The adjusting device 10 has a first adjusting element 17 which has a substantially arranged below the adhesive container 2 and aligned along the conveying direction 8 pneumatic cylinder 17a. Of course, another suitable design and arrangement of the first adjusting element 17 is possible, for example by means of a sprung eccentric, not shown, with which the respective applicator roller 3.1, 3.2 brought to the scoop roller 5 and is guided away from the scoop roller 5.

Die Antriebswelle 4 der Auftragswalzen 3.1, 3.2 ist rotierbar in einem ersten Schenkel 19.1 eines im Grundrahmen 6 aufgenommenen Schwenkgestells 9 gelagert. Demnach besitzen sowohl das Schwenkgestell 9 als auch die Antriebswelle 4 der Auftragswalzen 3.1, 3.2 jeweils eine Rotationsachse 9a, 4a, welche voneinander beabstandet angeordnet sind. Je nach aktueller Einstellung des ersten Stellelements 17 liegen diese beiden Rotationsachsen 9a, 4a vertikal mehr oder weniger genau übereinander. Ist die erste Auftragswalze 3.1 beispielsweise an die Schöpfwalze 5 herangeschwenkt, befindet sich die Rotationsachse 4a der ersten Auftragswalze 3.1 exakt senkrecht unterhalb der Rotationsachse 9a des Schwenkgestells 9 (Fig. 2, Fig. 4).The drive shaft 4 of the applicator rollers 3.1, 3.2 is rotatably mounted in a first leg 19. 1 of a pivot frame 9 accommodated in the base frame 6. Accordingly, both the pivot frame 9 and the drive shaft 4 of the applicator rollers 3.1, 3.2 each have a rotation axis 9a, 4a, which are arranged spaced from each other. Depending on the current setting of the first adjusting element 17, these two axes of rotation 9a, 4a are vertically more or less exactly one above the other. If the first application roller 3.1 is pivoted up, for example, to the scoop roller 5, the rotation axis 4a of the first application roller 3.1 is exactly perpendicular below the rotation axis 9a of the pivoting frame 9 (FIG. Fig. 2 . Fig. 4 ).

Das Schwenkgestell 9 weist dem Klebstoffbehälter 2 abgewandt einen sich im Wesentlichen entlang der Förderrichtung 8 erstreckenden zweiten Schenkel 19.2 auf, an dem ein zweites Stellelement 11 der Stelleinrichtung 10 mit dem Schwenkgestell 9 schwenkbar und gegenüber diesem drehfest angeordnet ist. Das zweite Stellelement 11 besitzt eine im Wesentlichen in Förderrichtung 8 ausgerichtete Spindel 11a und ist zum Einstellen eines Achsabstands 18 und eines Anpressdrucks zwischen der Schöpfwalze 5 und der jeweils an diese herangeschwenkten Auftragswalze 3.1, 3.2 vorgesehen (Fig. 4, Fig. 6). Das zweite Stellelement 11 ist mittels eines Stellantriebs 16 angetrieben und dazu über ein ebenfalls am zweiten Schenkel 19.2 des Gestells 9 angeordnetes Zahnrad 12 mit dem Stellantrieb 16 wirkverbunden. Ein abtriebsseitiges Ende 11 b des zweiten Stellelements 11 ist gegen den Grundrahmen 6 abstützbar ausgebildet. Dazu ist am Grundrahmen ein um die Rotationsachse 5a schwenkbarer Hebel 20 angeordnet, welcher eine Anschlagfläche 21 für das abtriebsseitige Ende 11 b der Spindel 11 a aufweist (Fig. 2, Fig. 3). Zum Einstellen des Achsabstands 18 zwischen der Schöpfwalze 5 und der jeweils an diese herangeschwenkten Auftragswalze 3.1, 3.2 wird von einer am Stellantrieb 16 angreifenden Maschinensteuerung 13 der Vorrichtung 1 ein Verstellweg des zweiten Stellelements 11 vorgegeben, welcher entsprechend der jeweils verwendeten Auftragswalze 3.1, 3.2 und dem jeweils zu bearbeitenden Buchblock ausgewählt ist.The pivoting frame 9, facing away from the adhesive container 2, has a second leg 19.2 extending essentially along the conveying direction 8, on which a second adjusting element 11 of the adjusting device 10 is pivotally arranged with respect to the pivoting frame 9 and non-rotatable relative thereto. The second actuating element 11 has a substantially aligned in the conveying direction 8 spindle 11a and is provided for adjusting a center distance 18 and a contact pressure between the scoop roller 5 and the respectively driven thereto applicator roller 3.1, 3.2 ( Fig. 4 . Fig. 6 ). The second actuating element 11 is driven by means of an actuator 16 and to this via a likewise arranged on the second leg 19.2 of the frame 9 gear 12 operatively connected to the actuator 16. An output-side end 11 b of the second actuating element 11 is designed to be supportable against the base frame 6. For this purpose, a pivotable about the rotation axis 5a lever 20 is arranged on the base frame, which has a stop surface 21 for the output-side end 11 b of the spindle 11 a ( Fig. 2 . Fig. 3 ). To adjust the distance between the scoop roller 18 between the scoop roller 5 and the respectively pivoted to this applicator roller 3.1, 3.2 is set by an attacking on the actuator 16 machine control 13 of the device 1, an adjustment of the second control element 11, which according to the applicator roller 3.1, 3.2 and the each book block to be edited is selected.

Der Pneumatikzylinder 17a ist mit einem ersten Ende 17.1 am Grundrahmen 6 befestigt. Mit einem zweiten, zu den Auftragswalzen 3.1, 3.2 ausgerichteten Ende 17.2 ist der Pneumatikzylinder 17a mit dem ersten Schenkel 19.1 des Schwenkgestells 9 verbunden.The pneumatic cylinder 17a is attached to the base frame 6 with a first end 17.1. With a second, aligned to the applicator rollers 3.1, 3.2 end 17.2 the pneumatic cylinder 17a is connected to the first leg 19.1 of the pivoting frame 9.

Die beiden Stellelemente 17, 11, d.h. der Pneumatikzylinder 17a und die Spindel 11a wirken gemeinsam bzw. gegeneinander. Sie weisen jeweils eine Achse 17c, 11 c auf, welche in einer vertikalen Ebene durch die Förderrichtung 8 einen variablen Stellwinkel 14 einschließen (Fig. 3). Der Stellwinkel 14 ist variabel, um zu ermöglichen, dass das zweite Stellelement 11 gemeinsam mit den Auftragswalzen 3.1, 3.2 geschwenkt werden kann. Unterschiedliche Durchmesser der Auftragswalzen 3.1, 3.2 werden beim Verstellen des zweiten Stellelements 11 berücksichtigt, sodass das Verstellen des ersten Stellelements 17 hiervon unabhängig bleibt.The two adjusting elements 17, 11, ie the pneumatic cylinder 17a and the spindle 11a act together or against each other. They each have an axis 17 c, 11 c, which in a vertical plane through the conveying direction 8 include a variable adjustment angle 14 ( Fig. 3 ). The adjusting angle 14 is variable in order to enable the second adjusting element 11 to be pivoted together with the applicator rollers 3.1, 3.2. Different diameters of the application rollers 3.1, 3.2 are taken into account when adjusting the second control element 11, so that the adjustment of the first control element 17 thereof remains independent.

Die Abmessungen des Pneumatikzylinders 17a sind so gewählt, dass er im ausgefahrenen Zustand die Auftragswalze jeweilige 3.1, 3.2 von der Schöpfwalze 5 so weit abhebt, dass diese beim Auswechseln die Schöpfwalze 5 nicht berührt. In der eingefahrenen Stellung wird die Auftragswalze 3.1, 3.2 durch den Pneumatikzylinder 17a an die Schöpfwalze 5 angedrückt.The dimensions of the pneumatic cylinder 17a are selected so that in the extended state, the applicator roller 3.1, 3.2 so far apart from the scoop roller 5 that it does not touch the scoop roller 5 when replacing. In the retracted position, the applicator roller 3.1, 3.2 is pressed by the pneumatic cylinder 17a to the scoop roller 5.

Sobald beim Heranschwenken der jeweiligen Auftragswalze 3.1, 3.2 an die Schöpfwalze 5 das abtriebsseitige Ende 11 b der Spindel 11 a an der Anschlagfläche 21 des am Grundrahmen 6 angeordneten schwenkbaren Hebels 20 anliegt, wird ein weiteres Heranschwenken der Auftragswalze 3.1, 3.2 mittels des Pneumatikzylinders 17a begrenzt (Fig. 2, Fig. 4, Fig. 6). Bei richtiger Druckeinstellung am Pneumatikzylinder 17a hat die Spindel 11 a mit dem abtriebsseitigen Ende 11 b Kontakt mit der Anschlagfläche 21 am Hebel 20 und drückt dabei nur leicht gegen diese Anschlagfläche 21. Die Hublänge des Pneumatikzylinders 17a ist dabei so gewählt, dass er die Funktion einer pneumatischen Feder übernimmt, d.h. im Einfahrzustand darf ein Zylinderkolben 17b des Pneumatikzylinders 17a nie die Endstellung erreichen. Dadurch steht der Luftdruck an einer Seite der Kolbenfläche des Zylinderkolbens 17b an und der Pneumatikzylinder 17a wirkt wie eine Zugfeder. Auf diese Weise wird der Pneumatikzylinder 17a auch nach dem Heranschwenken der Auftragswalze 3.1, 3.2 an die Schöpfwalze 5 beaufschlagt und die Auftragswalze 3.1, 3.2 federnd gegen die Schöpfwalze 5 angepresst. Zusätzlich kann der Anpressdruck der Auftragswalze 3.1, 3.2 mittels eines Proportionalventils 17d oder eines nicht dargestellten Druckminderers variabel eingestellt werden.As soon as the respective applicator roller 3.1, 3.2 to the scoop roller 5 abuts the output side end 11 b of the spindle 11 a on the stop surface 21 of the pivotal lever 20 disposed on the base frame 6, a further pivoting of the applicator roller 3.1, 3.2 limited by means of the pneumatic cylinder 17 a ( Fig. 2 . Fig. 4 . Fig. 6 ). With the correct pressure setting on the pneumatic cylinder 17 a, the spindle 11 a with the output side end 11 b contact with the stop surface 21 on the lever 20 and presses only slightly against this stop surface 21. The stroke length of the pneumatic cylinder 17 a is chosen so that it has the function of pneumatic spring takes over, ie in the retracted state a cylinder piston 17b of the pneumatic cylinder 17a may never reach the end position. As a result, the air pressure is applied to one side of the piston surface of the cylinder piston 17b and the pneumatic cylinder 17a acts as a tension spring. In this way, the pneumatic cylinder 17a is acted upon by the pivoting of the applicator roller 3.1, 3.2 to the scoop roller 5 and the applicator roller 3.1, 3.2 resiliently against the Scoop roller 5 pressed. In addition, the contact pressure of the applicator roller 3.1, 3.2 can be variably adjusted by means of a proportional valve 17d or a pressure reducer, not shown.

Wenn ein Buchblock mit einem nach oben versetztem Rücken zur Auftragswalze 3.1, 3.2 gelangt, drückt er von unten gegen die Auftragswalze 3.1, 3.2. Die Druckkraft wird über die Antriebswelle 4 in das Schwenkgestell 9 und über dieses in den Hebel 20 eingeleitet. Dieser schwenkt um die Rotationsachse 5a der Schöpfwalze 5, was dazu führt, dass die Auftragswalze 3.1, 3.2 nach oben ausweichen kann. Dabei wird der Achsabstand 18 zwischen der Rotationachse 5a der Schöpfwalze 5 und der Rotationsachse 4a der Antriebswelle 4 der Auftragswalze 3.1, 3.2 wegen der Druckkraft des Pneumatikzylinders 17a kaum verändert, weil diese dafür sorgt, dass der Kontakt zwischen der Spindel 11 a und der Anschlagfläche 21 des Hebels 20 nicht verloren geht. Die Auftragswalze 3.1, 3.2 kann dadurch während des Auftragens des Klebstoffs auf einen vom vorherigen Buchblock in seiner Höhenlage abweichenden, nachfolgenden Buchblock unter Beibehaltung sowohl des Achsabstands 18 als auch des Anpressdrucks zur Schöpfwalze 5 der Abweichung entsprechend in ihrer Höhenlage angepasst werden und insbesondere bei einem mit seinem Rücken nach oben vorstehenden Buchblock nach oben ausweichen.If a book block with an offset back up to the applicator roll 3.1, 3.2, he pushes from below against the applicator roll 3.1, 3.2. The pressure force is introduced via the drive shaft 4 in the pivot frame 9 and via this in the lever 20. This pivots about the axis of rotation 5a of the scoop roller 5, which causes the applicator roller 3.1, 3.2 can escape upwards. In this case, the axial distance 18 between the rotation axis 5a of the scoop roller 5 and the rotation axis 4a of the drive shaft 4 of the applicator roller 3.1, 3.2 hardly changed because of the pressure force of the pneumatic cylinder 17a, because this ensures that the contact between the spindle 11a and the stop surface 21st of the lever 20 is not lost. The applicator roller 3.1, 3.2 can thereby be adjusted during the application of the adhesive to a deviating from the previous book block in height, subsequent book block while maintaining both the center distance 18 and the contact pressure to the scoop roller 5 of the deviation according to their altitude and especially in a Dodge his bookcase upwards from his back.

Da die zur Änderung des Achsabstands 18 der Auftragswalzen 3.1, 3.2 eingesetzte Spindel 11 a am Schwenkgestell 9 der Vorrichtung 1 angeordnet ist, ist sie gemeinsam mit dem Schwenkgestell 9 um dessen Rotationsachse 9a schwenkbar. Damit ist die Spindel 11 a jederzeit einsatzbereit und bedarf dazu keiner Wechselstellung. Dies hat eine sehr kostengünstige Lösung zur Folge, mit der sich die Umstellung auf den nachfolgenden Fertigungsauftrag deutlich vereinfachen lässt.Since the spindle 11 a used for changing the axial spacing 18 of the applicator rollers 3.1, 3.2 is arranged on the pivoting frame 9 of the device 1, it is pivotable together with the pivoting frame 9 about its axis of rotation 9 a. Thus, the spindle 11 a is always ready for use and requires no change position. This results in a very cost-effective solution, which can significantly simplify the conversion to the subsequent production order.

Beim Abarbeiten eines aktuellen Fertigungsauftrags zur Herstellung von Büchern entnimmt die Schöpfwalze 5 dem Klebstoffbehälter 2 einen Klebstoff und überträgt diesen in einer Auftragsstellung in Form eines Klebstofffilms auf eine der Auftragswalzen 3.1, 3.2, die dazu vorgängig an die Schöpfwalze 5 herangeschwenkt worden ist. Zwischen der Schöpfwalze 5 und dem Klebstoffbehälter 2 ist dazu ein nicht gezeigter Leimspalt eingestellt.When processing a current production order for the production of books, the scoop roller 5 removes an adhesive from the adhesive container 2 and transfers it to an applicator position in the form of an adhesive film on one of the applicator rollers 3.1, 3.2, which has been pivoted to the scoop roller 5 in advance is. Between the scoop roller 5 and the adhesive container 2, a glue gap, not shown, is set for this purpose.

Dabei sind die Drehrichtungen der jeweiligen Auftragswalze 3.1, 3.2 und der Schöpfwalze 5 gleichsinnig. Der Klebstofffilm wird in der Auftragsstellung von der Mantelfläche 7.1, 7.2 der jeweiligen Auftragswalze 3.1, 3.2 auf den Rücken des Buchblocks übertragen, wobei sich der Buchblock und der mit dem Buchblock in Kontakt befindliche Abschnitt der Mantelfläche 7.1, 7.2 entlang der Förderrichtung 8 bewegen.The directions of rotation of the respective applicator roller 3.1, 3.2 and the scoop roller 5 are in the same direction. The adhesive film is transferred in the order position of the lateral surface 7.1, 7.2 of the respective applicator roll 3.1, 3.2 on the back of the book block, with the book block and located in contact with the book block section of the lateral surface 7.1, 7.2 move along the conveying direction 8.

Beim Auswechseln einer Auftragswalze 3.1, 3.2 dient das erste Stellelement 17 zum Heranschwenken bzw. zum Wegschwenken der jeweiligen Auftragswalze 3.1, 3.2 an die bzw. von der Schöpfwalze 5. Mittels des zweiten Stellelements 11 ist der Achsabstand 18 zwischen der Schöpfwalze 5 und der jeweiligen Auftragswalze 3.1, 3.2 einstellbar. Die Maschinensteuerung 13 kann dazu entweder einen Verstellweg für das zweite Stellelement 11 und damit für einen entsprechenden Verstellweg der jeweiligen Auftragswalze 3.1, 3.2 und zudem auch einen Anpressdruck der Auftragswalze 3.1, 3.2 an die Schöpfwalze 5 vorgeben. Dies ist deshalb vorteilhaft weil die Schöpfwalze 5 an ihrem Umfang konvex geformt ist und der Klebstoff ohne eine entsprechende Verstellung der Auftragswalzen 3.1, 3.2 nicht vollständig übertragen werden könnte.When replacing an applicator roller 3.1, 3.2 is the first actuator 17 for pivoting or for pivoting the respective applicator roller 3.1, 3.2 to or from the scoop roller 5. By means of the second control element 11, the center distance 18 between the scoop roller 5 and the respective applicator roll 3.1, 3.2 adjustable. For this purpose, the machine controller 13 can either pretend an adjusting path for the second adjusting element 11 and thus for a corresponding adjustment path of the respective applicator roller 3.1, 3.2 and also a contact pressure of the applicator roller 3.1, 3.2 to the scoop roller 5. This is advantageous because the scoop roller 5 is convexly formed at its periphery and the adhesive could not be completely transferred without a corresponding adjustment of the applicator rollers 3.1, 3.2.

Da der Maschinensteuerung 13 die jeweils zum Einsatz kommenden Auftragswalzen 3.1, 3.2 durch die vorliegenden Formatdaten der zu produzierenden Buchblocks bekannt sind, können sowohl der erforderliche Achsabstand 18 als auch der entsprechende Anpressdruck über mit der Maschinensteuerung 13 wirkverbundene Antriebe vorteilhaft voreingestellt werden. Damit kann der relativ große Unterschied einer flachen gegenüber einer runden Auftragswalze kompensiert und ein mit erhöhtem Verschleiß verbundener, zu großer Anpressdruck der jeweiligen Anpresswalze 3.1, 3.2 vermieden werden.Since the machine control 13, the respectively used applicator rollers 3.1, 3.2 are known by the present format data of the book block to be produced, both the required center distance 18 and the corresponding contact pressure can be advantageously preset via operatively connected to the machine control 13 drives. Thus, the relatively large difference of a flat compared to a round applicator roll compensated and associated with increased wear, excessive contact pressure of the respective pressure roller 3.1, 3.2 can be avoided.

Wenn bei der Buchproduktion ein dem aktuellen Arbeitsauftrag nachfolgender Arbeitsauftrag und insbesondere eine damit verbundene Änderung des Formats der Buchblocks einen Wechsel der Auftragswalzen 3.1, 3.2 erforderlich macht, wird auf an sich bekannte Weise zunächst der Leimspalt der Schöpfwalze 5 auf null reduziert. Damit wird der auf der beim abgeschlossenen Arbeitsauftrag zum Auftragen des Klebstoffs auf die Rücken der Buchblocks verwendeten Auftragswalze 3.1, 3.2 verbliebene Klebstoff auf die Schöpfwalze 5 übertragen und von dort zurück in den Klebstoffbehälter 2 gefördert. Sodann wird die gemäß Figur 1 bis dahin verwendete erste Auftragswalze 3.1 mittels des mit deren Antriebswelle 4 verbundenen sowie mit der Maschinensteuerung 13 wirkverbundenen, ersten Stellelements 17 der Stelleinrichtung 10 von der Schöpfwalze 5 weggeschwenkt und danach mittels des ebenfalls mit der Antriebswelle 4 verbundenen sowie mit der Maschinensteuerung 13 wirkverbundenen zweiten Stellelements 11 der Stelleinrichtung 10 ein Achsabstand 18 und ein Anpressdruck zwischen der Rotationsachse 4a der Antriebswelle 4 der Auftragswalzen 3.1, 3.2 und der Rotationsachse 5a der Schöpfwalze 5 voreingestellt. Nachdem die erste Auftragswalze 3.1 aus der Vorrichtung 1 entfernt, d.h. axial von ihrer Antriebwelle 4 heruntergeschoben sowie abtransportiert worden ist, wird die für den nachfolgenden Arbeitsauftrag benötigte zweite Auftragswalze 3.2 in die Vorrichtung 1 eingeführt, d.h. axial auf die Antriebswelle 4 geschoben und dort arretiert. Danach wird der Leimspalt der Schöpfwalze 5 wiederhergestellt und die zweite Auftragswalze 3.2 mittels des ersten Stellelements 17 wieder an die Schöpfwalze 5 herangeschwenkt. Dazu werden das erste und das zweite Stellelement 17, 11 durch die Maschinensteuerung 13 entsprechend angesteuert. Auf diese Weise ist die zweite Auftragswalze 3.2 innerhalb kurzer Zeit auf den nachfolgenden Arbeitsauftrag eingestellt und kann Klebstoff beispielsweise auf Buchblocks mit verändertem Format auftragen.If, in book production, a work order subsequent to the current work order, and in particular a change in the format of the book blocks associated therewith, necessitates a change of the application rollers 3.1, 3.2, then In a known manner, first the glue gap of the scoop roller 5 is reduced to zero. In order for the used on the work order for applying the adhesive to the back of the book block used applicator roller 3.1, 3.2 remaining adhesive is transferred to the scoop roller 5 and conveyed from there back into the adhesive container 2. Then the according to FIG. 1 until then used first application roller 3.1 by means of the drive shaft 4 connected and operatively connected to the machine control 13, the first actuating element 17 of the actuator 10 is pivoted away from the scoop roller 5 and then by means of the also connected to the drive shaft 4 and operatively connected to the machine control 13 second actuator 11th the adjusting device 10, a center distance 18 and a contact pressure between the rotation axis 4a of the drive shaft 4 of the applicator rollers 3.1, 3.2 and the rotation axis 5a of the scoop roller 5 preset. After the first applicator roll 3.1 removed from the device 1, that is axially pushed down from its drive shaft 4 and transported away, the second application roller 3.2 required for the subsequent work order is introduced into the device 1, that is axially pushed onto the drive shaft 4 and locked there. Thereafter, the glue gap of the scoop roller 5 is restored and the second application roller 3.2 by means of the first control element 17 pivoted back to the scoop roller 5. For this purpose, the first and the second control element 17, 11 are driven by the machine control 13 accordingly. In this way, the second application roller 3.2 is set within a short time to the subsequent work order and can apply adhesive, for example, on book blocks with a different format.
