Description

Die Erfindung betrifft einen Klebebinder mit einem Maschinengestell, mit einer Mehrzahl am Maschinengestell befestigter Bearbeitungsstationen, mit mindestens zwei Transportklammern zum Transport von Buchblocks, mindestens einer geschlossenen Führungsbahn für die Transportklammern und mindestens einer Einrichtung zum Verändern des Aushangs der Buchblocks.The invention relates to an adhesive binder with a machine frame, with a plurality of machining stations fixed to the machine frame, with at least two transport clamps for transporting book blocks, at least one closed guideway for the transport clamps and at least one means for changing the posting of the book block.

Klebebinder dienen der Herstellung von klebegebundenen Büchern (Softcover) oder von Buchblocks für Bücher mit Festeinbänden (Hardcover), wobei zu einem Buchblock zusammengetragene Falzbogen und/oder Einzelblätter durch Auftragen eines üblichen Klebstoffs bzw. Leims auf den zuvor bearbeiteten Blockrücken miteinander verbunden und abschliessend mit einem Umschlag (Softcover) oder mit einem Fälzelstreifen (Hardcover) versehen werden. Beim Aushang handelt es sich um einen aus einer Transportklammer des Klebebinders in Richtung der jeweiligen Bearbeitungsstation überstehenden Rückenbereich eines Buchblocks, an welchem die verschiedenen Bearbeitungsschritte im Klebebinder stattfinden. In Abhängigkeit solcher Bearbeitungsschritte, wie beispielsweise dem Anbringen eines Umschlags oder eines Fälzelstreifens am Buchblock, kann eine Veränderung des Aushangs erforderlich sein.
Die möglichen Bindeverfahren und die Produktvarianten sind üblicherweise von der Maschinenausrüstung des Klebebinders abhängig. Letztere besteht im Wesentlichen aus den Funktionseinheiten: Blocktransportsystem, Blockeinführstation, Rückenbearbeitung (Rückenfräsen), Rückenbeleimung, Zwischentrocknung, Seitenbeleimung, Rückenverstärkung, Umschlag und/oder Fälzelstreifen anlegen, Umschlag und/oder Fälzelstreifen andrücken, Auslagestation und Trocknung.Perfect binders are used for the production of hardcover books (softcover) or book blocks for hardcover books, wherein folded sheets and / or single sheets brought together to form a book block are joined together by applying a conventional adhesive or glue to the previously processed block spine and finally with a Envelope (softcover) or be provided with a Fälzelstreifen (hardcover). When posting is a protruding from a transport bracket of Klebebinders in the direction of the respective processing station back portion of a book block on which the various processing steps take place in the perfect binder. Depending on such processing steps as attaching an envelope or crimp strip to the book block, a change in the notice may be required.
The possible binding methods and the product variants are usually dependent on the machine equipment of the perfect binder. The latter essentially consists of the functional units: Block transport system, Blockeinführstation, back processing (back milling), Rückenbeleimung, intermediate drying, Seitenbeleimung, back reinforcement, cover and / or Fälzelstreifen create, press envelope and / or Fälzelstreifen, delivery station and drying.

Nach dem Stand der Technik kommen bei Klebebindern als Fördermittel vorzugsweise Rollenketten mit einzeln, beweglich ineinander greifenden Gliedern zum Einsatz. Die Ketten dienen dem Vortrieb der Transportklammern. Geführt werden die Transportklammern durch eine mit dem Maschinengestell des Klebebinders verbundene Führungsbahn. Dazu besitzt jede Transportklammer mehrere Laufrollen, welche auf der Lauffläche der Führungsbahn abrollen.According to the state of the art, adhesive binders preferably use roller chains with individually, movably interlocking members as conveying means. The chains serve to drive the transport clamps. The transport clamps are guided by a machine frame of the perfect binder connected guideway. For this purpose, each transport clamp has a plurality of rollers, which roll on the running surface of the guideway.

Neben Klebebindern mit Zusammentragmaschine und somit automatischer Beschickung sind auch Kleinklebebinder mit Start-Stopp-Betrieb bekannt, welche oft eine Handanlage besitzen. Dabei werden die Buchblocks vom Maschinenbediener in einer Blockeinführstation einzeln und manuell in eine stillstehende Transportklammer eingeführt. Anschliessend bewegt die Transportklammer den Buchblock entlang verschiedener Bearbeitungsstationen durch den Klebebinder.In addition to perfect binders with gathering machine and thus automatic feeding and small containers with start-stop operation are known, which often have a manual system. The book blocks are introduced by the machine operator in a block insertion station individually and manually in a stationary transport clamp. Subsequently, the transport clamp moves the book block along various processing stations through the perfect binder.

Ein Klebebinder mit automatischer Beschickung wird beispielsweise in der EP2738011 A2 beschrieben. Dieser Klebebinder besitzt mehrere Bearbeitungsstationen, wie beispielsweise Blockeinführstation, Rückenbearbeitungsstation (Rückenfräse), Leimauftragsstation, Leimauftragskontrolle, Umschlaganleger und/oder Fälzelstation, Umschlag- und/oder Fälzelanpressstation, Auslagestation und Trockenstation. Weiterhin verfügt dieser Klebebinder über mindestens zwei Transportklammern zum Transport von Buchblocks sowie über mindestens eine geschlossene Führungsbahn, auf welcher die Transportklammern umlaufen und die Bearbeitungsstationen passieren.An adhesive binder with automatic loading, for example, in the EP2738011 A2 described. This perfect binder has several processing stations, such as Blockeinführstation, back processing station (back router), glue application station, glue application control, Umschlaganleger and / or Fälzelstation, handling and / or Fälzelanpressstation, delivery station and drying station. Furthermore, this perfect binder has at least two transport clamps for transporting book blocks as well as at least one closed guideway on which the transport clamps rotate and pass through the processing stations.

Die Möglichkeit Bücher als Einzelstücke oder in einer kleinen Stückzahl zu produzieren wird in zunehmendem Maße nicht nur im Softcover-Bereich, sondern zur Herstellung gefälzelter Buchblocks auch im Hardcover-Bereich nachgefragt. Um solche Buchblocks für Hardcover-Bücher herzustellen bedarf es eines Klebebinders, welcher mit einer Fälzelstation ausgerüstet ist. Beim Anbringen von Fälzelstreifen ist es in Abhängigkeit vom Endprodukt notwendig, den seitlichen Überstand des Fälzelmaterials über den Blockrücken in einem bestimmten Bereich definiert einstellen zu können. Einerseits muss dazu ein Fälzelstreifen in den entsprechenden Abmessungen von der Fälzelstation bereitgestellt werden, andererseits muss der Aushang der zu bindenden Buchblocks größer sein als der gewünschte Überstand des Fälzelmaterials.The possibility of producing books as individual pieces or in small numbers is increasingly in demand, not only in the softcover sector, but also in the production of folded book blocks in the hardcover sector. To make such book blocks for hardcover books requires an adhesive binder, which is equipped with a Fälzelstation. When attaching Fälzelstreifen it is necessary depending on the final product to be able to set the lateral projection of the Fälzelmaterials defined over the block back in a certain range. On the one hand a Fälzelstreifen must be provided in the appropriate dimensions of the Fälzelstation, on the other hand, the notice of the book block to be bound must be greater than the desired supernatant of the Fälzelmaterials.

Gemäss S. 307 des Lehrbuchs "Industrielle Buchbinderei" von Liebau/Heinze, 2001 (ISBN 3-88013-596-7), ist der Aushang in bestimmten Grenzen wählbar. Mit anderen Worten ist daher eine Einrichtung zum Anpassen des Aushangs an die technologischen Bedingungen bei Klebebindern grundsätzlich bekannt. Da die Transportklammern der bisherigen Klebebinder gestellfest angeordnet, d.h. während des Klebebindens fest mit dem Maschinengestell bzw. mit einer Tragkonstruktion verbunden ist, muss bei einer Veränderung des Aushangs zunächst die Position einer als Ruhe-/Rütteltisch ausgebildeten Bearbeitungsstation relativ zu den Transportklammern verstellt werden. Alle weiteren Bearbeitungsstationen, wie beispielsweise Rückenfräse, Leimwerke, Umschlaganlege- und/oder Fälzelstation, Anpressstation und Auslagestation, müssen ebenfalls an diese Veränderung angepasst werden. Dies kann manuell, aber bei modernen Anlagen auch motorisch erfolgen.According to page 307 of the textbook "Industrielle Buchbinderei" by Liebau / Heinze, 2001 (ISBN 3-88013-596-7), the notice can be selected within certain limits. In other words, therefore, a device for adapting the notice to the technological conditions in perfect binders is basically known. Since the transport brackets of the previous perfect binder arranged fixed to the frame, i. is firmly connected to the machine frame or with a support structure during adhesive binding, the position of a designed as resting / vibrating table processing station must be adjusted relative to the transport brackets at a change of the notice first. All other processing stations, such as back milling machine, gluing units, handling and / or felling station, pressing station and delivery station, must also be adapted to this change. This can be done manually, but in modern systems also by motor.

In den Bearbeitungsstationen ist jedoch ein erheblicher Aufwand an Mechanik, wie Linearführungen an Aktoren, wie Stellachsen mit Stellmotoren sowie an Sensorik notwendig, um die Aufgabe einer solchen Einrichtung zum Verändern des Aushangs der Buchblocks zu realisieren und die geforderten Positionsgenauigkeiten von ca. 0,1 mm einzuhalten. Dazu kommen auch relativ komplizierte Abläufe in der Software.In the processing stations, however, a considerable amount of mechanics, such as linear guides on actuators, such as adjusting axes with actuators and sensors is necessary to realize the task of such a device for changing the notice of the book block and the required position accuracies of about 0.1 mm observed. There are also relatively complicated processes in the software.

Würde man dem bisher bekannten Lösungsweg folgen, könnte dies insbesondere die Entwicklung einer höheneinstellbaren Rückenfräse mit massiven und hochwertigen Linearführungen zur Folge haben. Weiterhin müssten alle Arten von Leimwerken, wie Hotmelt-Walzenleimwerk, PUR-Düsenleimwerk und Seitenleimwerk, höheneinstellbar ausgeführt werden, was insbesondere bei einer Option "mobile, wechselbare Leimwerke" zu komplizierten konstruktiven Lösungen führen könnte.If one followed the previously known solution, this could in particular have the development of a height-adjustable back router with massive and high-quality linear guides result. Furthermore, all types of gluing plants, such as hot melt gluing unit, PUR nozzle gluing unit and side gluing unit, would have to be adjustable in height, which could lead to complicated constructive solutions, in particular with an option "mobile, interchangeable gluing units".

Ein weiteres Problem speziell im Bereich von Kleinklebebindern sind die damit verbundenen Kosten, welche unabhängig von dem Vorhandensein einer Fälzelstation und damit der Möglichkeit Buchblocks für Hardcover-Bücher zu fertigen, entstehen.Another problem, especially in the field of Kleinkbleebindern are the associated costs, which regardless of the presence of a Fälzelstation and thus the ability to produce book block for hardcover books arise.

Aufgabe der Erfindung ist es, die Nachteile des Standes der Technik zu überwinden und einen Klebebinder bereit zu stellen, mit dem eine technologisch bedingte Veränderung des Aushangs technisch einfach und damit kostengünstig sowie sicher realisiert werden kann. Diese technische Lösung soll außerdem geeignet sein, um auch in Kleinklebebindern ökonomisch vertretbar eingesetzt zu werden. Schliesslich soll die Lösung sowohl zur Herstellung von Softcover-Büchern als auch von Buchblocks für Hardcover-Bücher geeignet sein.The object of the invention is to overcome the disadvantages of the prior art and to provide an adhesive binder with which a technologically induced change of the notice can be realized technically simple and therefore cost-effective and secure. This technical solution should also be suitable to be economically acceptable used in small children. Finally, the solution should be suitable both for the production of softcover books and book blocks for hardcover books.

Die Aufgabe der Erfindung wird durch einen Klebebinder mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen dieses Klebebinders sind Gegenstand der Unteransprüche 2 bis 11.The object of the invention is achieved by an adhesive binder with the features of the characterizing part of claim 1. Advantageous embodiments of this adhesive binder are the subject of the dependent claims 2 to 11.

Erfindungswesentlich ist dabei, dass die mindestens eine Einrichtung zum Verändern des Aushangs der Buchblocks derart mit einer Unterkante mindestens einer der Transportklammern zusammenwirkend angeordnet ist, dass diese Unterkante in mehreren parallel zur mindestens einen geschlossenen Führungsbahn der Transportklammern verlaufenden, ersten Ebenen des Klebebinders positionierbar ist. Aufgrund dieser Ausbildung des Klebebinders kann die Veränderung des Aushangs technisch einfach und damit kostengünstig, sicher und ohne Verstellung von Bearbeitungsstationen realisiert werden. Weil gegenüber dem Stand der Technik somit nur noch ein Parameter des Klebebinders verändert werden muss, ergibt sich zudem eine einfachere Maschinenführung durch das Bedienpersonal.Essential to the invention is that the at least one means for changing the notice of the book block is arranged cooperatively with a lower edge of at least one of the transport brackets, that this lower edge is positionable in a plurality of parallel to the at least one closed guideway of the transport clamps extending first levels of Klebebinders. Due to this design of the perfect binder, the change of the notice can be realized technically simple and therefore cost-effective, safe and without adjustment of processing stations. Because compared to the prior art thus only one parameter of the perfect binder must be changed, also results in a simpler machine management by the operator.

In einer Ausführungsform des erfindungsgemässen Klebebinders ist die mindestens eine geschlossene Führungsbahn des Klebebinders in mehreren parallel zueinander verlaufenden, zweiten Ebenen positionierbar. Dadurch ist eine besonders einfache und sichere Veränderung der Position der Führungsbahn und somit des Aushangs möglich. Generell verlaufen sowohl die ersten als auch die zweiten Ebenen horizontal, d.h. parallel zur Aufstellfläche bzw. zum Maschinengestell des Klebebinders. Demgegenüber ist natürlich auch ein beliebig geneigter Verlauf dieser Ebenen möglich.In one embodiment of the adhesive binder according to the invention, the at least one closed guideway of the perfect binder can be positioned in a plurality of mutually parallel, second planes. As a result, a particularly simple and secure change in the position of the guideway and thus the notice is possible. In general, both the first and the second planes are horizontal, ie parallel to the mounting surface or to the machine frame of the perfect binder. In contrast, of course, an arbitrarily inclined course of these levels is possible.

In einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist die mindestens eine Einrichtung zum Verändern des Aushangs der Buchblocks zwischen der mindestens einen geschlossenen Führungsbahn der Transportklammern und dem Maschinengestell des Klebebinders angeordnet. Auf diese Weise kann eine besonders einfache und platzsparende Lösung realisiert werden.In a further embodiment of the adhesive binder according to the invention, the at least one device for changing the posting of the book block is arranged between the at least one closed guide track of the transporting clamps and the machine frame of the perfect binder. In this way, a particularly simple and space-saving solution can be realized.

In einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist die mindestens eine geschlossene Führungsbahn der Transportklammern mit einer Grundplatte verbunden. Dabei ist die mindestens eine Einrichtung zum Verändern des Aushangs der Buchblocks zwischen der Grundplatte und dem Maschinengestell des Klebebinders angeordnet. Mit einer solchen Grundplatte kann einerseits eine einfache und kostengünstige Abstützung der mindestens einen geschlossenen Führungsbahn erreicht werden. Andererseits kann die mindestens eine Einrichtung zum Verändern des Aushangs der Buchblocks vorteilhaft an der Grundplatte befestigt und/oder in dieser aufgenommen werden.In a further embodiment of the adhesive binder according to the invention, the at least one closed guideway of the transporting clamps is connected to a baseplate. In this case, the at least one device for changing the notice of the book block between the base plate and the machine frame of the perfect binder is arranged. With such a base plate, on the one hand, a simple and cost-effective support of the at least one closed guideway can be achieved. On the other hand, the at least one device for changing the notice of the book block can be advantageously attached to the base plate and / or received in this.

In einer nächsten Ausführungsform des erfindungsgemässen Klebebinders ist am Maschinengestell des Klebebinders ein Ruhe-/Rütteltisch für den Aushang des Buchblocks befestigt. Ein solcher Ruhe-/Rütteltisch bietet eine einfache und kostengünstige Lösung zur temporären Ablage des Aushangs des Buchblocks während dessen Verstellung. Mit einem Ruhe-/Rütteltisch wird der darauf abgesetzte, noch lose Buchblock in einer ersten Phase gerüttelt, wobei sich dessen einzelne Druckbogen und/oder Blätter zunächst aneinander ausrichten können. In einer zweiten Phase wird das Rütteln eingestellt, so dass der immer noch ungebundene Buchblock vor seiner Übernahme in die jeweilige Transportklammer zur Ruhe kommt und seine Druckbogen und/oder Blätter durch die Auflage auf dem Ruhe-/Rütteltisch eine definierte Position einnehmen. Ausgehend von dieser definierten Position kann der Aushang des Buchblocks eingestellt werden.In a next embodiment of the adhesive binder according to the invention, a resting / vibrating table for the posting of the book block is fastened to the machine frame of the perfect binder. Such a resting / vibrating table provides a simple and inexpensive solution for temporary storage of the notice of the book block during its adjustment. With a resting / vibrating table, the still loose block of books deposited thereon is shaken in a first phase, whereby its individual printed sheets and / or sheets can initially align with one another. In a second phase, the shaking is stopped, so that the still unbound book block comes to rest before its adoption in the respective transport clamp and take his sheets and / or sheets by resting on the resting / vibrating a defined position. Starting from this defined position, the notice of the book block can be adjusted.

In einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist die Unterkante mindestens einer der Transportklammern relativ zu den Bearbeitungsstationen parallel und vertikal verstellbar angeordnet. Einerseits ist eine solche Verstellung relativ einfach zu realisieren und andererseits bleiben dadurch die zu bearbeitenden Buchblocks zur Arbeitsposition der Bearbeitungswerkzeuge vorteilhaft immer gleich ausgerichtet. Auch die mindestens eine geschlossene Führungsbahn ist analog angeordnet.In a further embodiment of the adhesive binder according to the invention, the lower edge of at least one of the transporting clamps is arranged to be parallel and vertically adjustable relative to the processing stations. On the one hand, such an adjustment is relatively easy to implement, and on the other hand, they remain the same editing book block to the working position of the editing tools advantageous always aligned the same. The at least one closed guideway is arranged analogously.

In einer nächsten Ausführungsform des erfindungsgemässen Klebebinders ist für alle Transportklammern eine gemeinsame Einrichtung zum Verändern des Aushangs der Buchblocks angeordnet. Damit kann der Klebebinder einfach und schnell an die zu erwartenden Fertigungsaufträge angepasst werden. Natürlich kann auch an jeder Transportklammer eine Einrichtung zum Verändern des Aushangs der Buchblocks angeordnet sein, welche mit einer Maschinensteuerung des Klebebinders verbunden ist. Bei einer solchen Lösung können die Einrichtungen zum Verändern des Aushangs der Buchblocks mit der Maschinensteuerung entweder gemeinsam oder separat angesteuert werden.In a next embodiment of the adhesive binder according to the invention, a common device for changing the posting of the book block is arranged for all transport clamps. Thus, the perfect binder can be easily and quickly adapted to the expected production orders. Of course, a device for changing the notice of the book block can be arranged on each transport clamp, which is connected to a machine control of the perfect binder. In such a solution, the means for changing the posting of the book blocks with the machine control can be controlled either jointly or separately.

Gemäss einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist die Einrichtung zum Verändern des Aushangs der Buchblocks stufenlos oder endlagenbezogen verstellbar ausgebildet. Dadurch kann diese Einrichtung vorteilhaft entweder besonders genau oder besonders schnell betätigt werden.According to a further embodiment of the adhesive binder according to the invention, the device for changing the posting of the book block is designed to be infinitely variable or end position-related. As a result, this device can advantageously be actuated either particularly accurately or particularly quickly.

In einer nächsten Ausführungsform des erfindungsgemässen Klebebinders ist die Einrichtung zum Verändern des Aushangs der Buchblocks hydraulisch, elektromotorisch, pneumatisch und/oder mechanisch antreibbar ausgebildet. Dabei handelt es sich um eine Auswahl besonders vorteilhafter Lösungen für den Antrieb einer solchen Einrichtung.In a next embodiment of the adhesive binder according to the invention, the device for changing the posting of the book block is designed to be hydraulically, electromotively, pneumatically and / or mechanically drivable. It is a selection of particularly advantageous solutions for the drive of such a device.

In einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist dieser ein Kleinklebebinder. Damit wird aufgezeigt, dass die Lösung nicht nur für industrielle sondern auch für kleine Klebebinder geeignet ist, denen die zu bindenden Buchblocks zumeist manuell zugeführt werden.In a further embodiment of the adhesive binder according to the invention, this is a small-size adhesive binder. This shows that the solution is not only suitable for industrial but also for small perfect binders to which the book blocks to be bound are usually fed manually.

Gemäss einer weiteren Ausführungsform des erfindungsgemässen Klebebinders ist zumindest eine seiner Bearbeitungsstationen als Fälzelstation ausgebildet.According to a further embodiment of the adhesive binder according to the invention, at least one of its processing stations is designed as a folding station.

Demnach kann der Klebebinder neben der Herstellung von Softcover-Büchern auch zur Herstellung von Buchblocks für Hardcover-Bücher verwendet werden.Accordingly, the perfect binder can be used in addition to the production of softcover books for the production of book blocks for hardcover books.

Die Aufgabe der Erfindung wird außerdem durch die Merkmale des Anspruchs 12 gelöst.The object of the invention is also solved by the features of claim 12.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben. Dabei zeigen:

In Fig. 1 ist ein zur Herstellung von Softcover-Büchern oder von Buchblocks für die Herstellung von Hardcover-Büchern geeigneter, erfindungsgemässer Klebebinder 1 in einer Draufsicht dargestellt. Dieser Klebebinder 1 besitzt ein Buchblocktransportsystem 2 mit einer geschlossenen Führungsbahn 3, an welcher drei Transportklammern 11, 12, 13 jeweils mittels einer Führungsanordnung 35 durch an einem Maschinengestell 7 (Fig. 3, Fig. 4) des Klebebinders 1 befestigte und entlang der Führungsbahn 3 angeordnete Bearbeitungsstationen 5 hindurch bewegt werden. Beispielhaft für solche Bearbeitungsstationen 5 sollen hier eine Blockeinführstation, eine Rückenbearbeitungsstation (Rückenfräse), eine Leimauftragsstation, eine Leimauftragskontrolle, ein Umschlaganleger und/oder eine Fälzelstation, eine Umschlag- und/oder Fälzelanpressstation, eine Auslagestation und eine Trockenstation genannt werden.In Fig. 1 is a for the production of soft cover books or book blocks for the production of hardcover books suitable, inventive perfect binder 1 shown in a plan view. This perfect binder 1 has a book block transport system 2 with a closed guideway 3, on which three transporting clamps 11, 12, 13 each by means of a guide assembly 35 by on a machine frame 7 (Fig. Fig. 3 . Fig. 4 ) of the perfect binder 1 and arranged along the guide track 3 processing stations 5 are moved through. Examples of such processing stations 5 are here a Blockeinführstation, a back processing station (back router), a glue application station, a glue application control, a cover feeder and / or a Fälzelstation, a handling and / or Fälzelanpressstation, a delivery station and a drying station are called.

Zudem weist dieser Klebebinder 1 drei Antriebe 41, 42, 43 auf (Fig. 2), wobei ein erster Antrieb 41 einer ersten Transportklammer 11, ein zweiter Antrieb 42 einer zweiten Transportklammer 12 und ein dritter Antrieb 43 einer dritten Transportklammer 13 zugeordnet ist. Die Antriebe 41, 42, 43 besitzen jeweils eine Antriebskette 21, 22, 23, an welcher die zugeordnete Transportklammer 11, 12, 13 befestigt ist, und welche von einem Antriebsmotor 31, 32, 33 über jeweils ein Kettenrad 4 (Fig. 1) angetrieben wird. Die Antriebsmotoren 31, 32, 33 werden dabei von einer Maschinensteuerung 6 des Klebebinders 1 angesteuert. In der Maschinensteuerung 6 sind Geschwindigkeitsprofile hinterlegt, so dass die Transportklammern 11, 12, 13 jeweils mit einem eigenen Geschwindigkeitsprofil entlang der Führungsbahn 3 bewegt werden können. Natürlich kann auch ein Buchblocktransportsystem 2 Verwendung finden, welches lediglich mit zwei oder mit mehr als drei Transportklammern 11, 12, 13 sowie mit einer entsprechenden Anzahl von Antriebseinrichtungen ausgestattet ist.In addition, this perfect binder 1 has three drives 41, 42, 43 ( Fig. 2 ), wherein a first drive 41 of a first transporting clamp 11, a second drive 42 of a second transporting clamp 12 and a third drive 43 of a third transporting clamp 13 is assigned. The drives 41, 42, 43 each have a drive chain 21, 22, 23, to which the associated transport clamp 11, 12, 13 is attached, and which by a drive motor 31, 32, 33 via a respective sprocket 4 (FIG. Fig. 1 ) is driven. The drive motors 31, 32, 33 are controlled by a machine control 6 of the perfect binder 1. Speed profiles are stored in the machine controller 6 so that the transport clamps 11, 12, 13 can each be moved along the guide track 3 with their own speed profile. Of course, a book block transport system 2 can be used, which is equipped with only two or more than three transport clamps 11, 12, 13 and with a corresponding number of drive means.

Der Klebebinder 1 verfügt über eine Anzahl von Haltepositionen 51, 52, 53, in denen eine Transportklammer 11, 12, 13 jeweils von dem ihr zugeordneten Antrieb 41, 42, 43 zum Stillstand gebracht werden kann. Beispielsweise ist eine erste Halteposition 51 für das Einführen loser Buchblocks, eine zweite Halteposition 52 für das Anpressen eines nicht dargestellten Umschlags an einen Buchblock 100 und eine dritte Halteposition 53 für das Ausschleusen gebundener Buchblocks 100 dargestellt. Bei Vorhandensein einer als Fälzelstation zum Aufbringen eines Fälzelstreifens ausgebildeten Bearbeitungsstation 5 ist in deren Bereich eine weitere Halteposition vorgesehen. In der Maschinensteuerung 6 können für die Haltepositionen 51, 52, 53 unterschiedlich lange Stillstandzeiten hinterlegt werden.The perfect binder 1 has a number of holding positions 51, 52, 53, in which a transport clamp 11, 12, 13 can be brought to a standstill each of their associated drive 41, 42, 43. For example, a first holding position 51 for the insertion of loose book block, a second holding position 52 for pressing an envelope, not shown, to a book block 100 and a third holding position 53 for the discharge of bound book block 100 is shown. In the presence of a processing station 5 designed as a folding station for applying a trimming strip, a further holding position is provided in its area. In the machine control 6, different lengths of downtime can be stored for the holding positions 51, 52, 53.

In Fig. 2 ist der gleiche Klebebinder 1 in einer Seitenansicht aus Richtung des Pfeils II in Fig. 1 dargestellt, in der die Anordnung der als Teil des jeweiligen Antriebs 41, 42, 43 ausgebildeten Antriebsketten 21, 22, 23 deutlich zu erkennen ist. Die in den Transportklammern 11, 12, 13 aufgenommenen und mit dieser geförderten Buchblocks 100 weisen jeweils einen aus der Transportklammer 11, 12, 13 in Richtung der Bearbeitungsstationen 5 überstehenden Rückenbereich auf, welcher Aushang 10 genannt wird. An diesem eine Unterkante 11 a, 12a, 13a zumindest einer der Transportklammern 11, 12, 13 überragenden Aushang 10 finden die verschiedenen Bearbeitungsschritte im Klebebinder 1 statt. In Fig. 2 ist eine am Klebebinder 1 angeordnete Einrichtung 14 zum Verändern des Aushangs 10 der Buchblocks 100 und damit zur Veränderung von deren Abstand relativ zu den feststehenden Bearbeitungsstationen 5 lediglich schematisch gezeigt. Detailliert dargestellt ist diese Einrichtung 14 in Fig. 3 bzw. in Fig. 4.In Fig. 2 is the same perfect binder 1 in a side view from the direction of the arrow II in Fig. 1 represented, in which the arrangement of formed as part of the respective drive 41, 42, 43 drive chains 21, 22, 23 can be clearly seen. The recorded in the transport brackets 11, 12, 13 and funded with this book block 100 each have a from the transport bracket 11, 12, 13 in the direction of the processing stations 5 projecting back region, which is called notice 10. At this one lower edge 11 a, 12 a, 13 a at least one of the transport brackets 11, 12, 13 towering notice 10 find the various processing steps in the perfect binder 1 instead. In Fig. 2 is a device arranged on the perfect binder 1 14 for changing the notice 10 of Book block 100 and thus to change the distance relative to the stationary processing stations 5 shown only schematically. This device 14 is shown in detail in FIG Fig. 3 or in Fig. 4 ,

Fig. 3 zeigt eine Schnittdarstellung eines erfindungsgemässen Klebebinders 1 aus Richtung des Pfeils III in Fig. 1, wobei demgegenüber auch ein Maschinengestell 7 des Klebebinders 1 gezeigt ist. Zwischen zwei hintereinander stehenden Stützen 8 des Maschinengestells 7 ist eines von mehreren gestellfest am Klebebinder 1 angeordneten Tragelementen 17 zur Aufnahme der Einrichtung 14 zur Verstellung des Aushangs 10 dargestellt. Die Tragelemente 17 besitzen jeweils zwei vertikal angeordnete Ausnehmungen 18, wobei in jeder dieser Ausnehmungen 18 ein gleitgelagertes Führungselement 19 angeordnet ist. Außerdem weisen die Tragelemente 17 jeweils eine weitere vertikal angeordnete Ausnehmung 20 auf, in welcher ein Hydraulikzylinder 15 einer ansonsten nicht weiter dargestellten hydraulischen Hubeinheit angeordnet ist. Die beispielsweise als Einschraubzylinder ausgebildeten Hydraulikzylinder 15 sind stufenlos vertikal nach oben ausfahrbar und heben dabei eine die geschlossene Führungsbahn 3 tragende Grundplatte 24 vertikal an. Die Grundplatte 24 ist mit den beiden Führungselementen 19 an deren jeweiligem oberen Ende fest verbunden, beispielsweise verschraubt. An der Grundplatte 24 sind zwei zylinderförmige Stützelemente 25 befestigt, welche jeweils mit einer unteren Grundfläche 26 auf korrespondierenden ersten Flächen 27 eines in jeweils einer horizontalen Ausnehmung 28 des Tragelements 17 angeordneten, zylinderförmigen Exzenters 29 aufliegen. Die Einrichtung 14 zur Verstellung des Aushangs 10 weist somit die gleitgelagerten Führungselemente 19, die Hydraulikzylinder 15 der hydraulischen Hubeinheit, die zylinderförmigen Stützelemente 25 und die zylinderförmigen Exzenter 29 auf. Natürlich kann die Führungsbahn 3 auch ohne eine solche Grundplatte 24 oder ohne ein ähnliches Zwischenelement ausgebildet sein. In diesem Fall greift die Einrichtung 14 zum Verändern des Aushangs 10 der Buchblocks 100 direkt an der Führungsbahn 3 an. Fig. 3 shows a sectional view of an inventive adhesive binder 1 from the direction of arrow III in Fig. 1 In contrast, on the other hand, a machine frame 7 of the perfect binder 1 is shown. Between two successive supports 8 of the machine frame 7 one of several frame-fixedly arranged on perfect binder 1 supporting elements 17 for receiving the device 14 for adjusting the notice 10 is shown. The support elements 17 each have two vertically arranged recesses 18, wherein in each of these recesses 18, a slide-mounted guide member 19 is arranged. In addition, the support elements 17 each have a further vertically arranged recess 20, in which a hydraulic cylinder 15 of an otherwise not shown hydraulic lifting unit is arranged. The trained example as screw-in hydraulic cylinder 15 are infinitely extendable vertically upwards and lift while a closed guideway 3 bearing base plate 24 vertically. The base plate 24 is fixedly connected to the two guide elements 19 at their respective upper end, for example screwed. On the base plate 24, two cylindrical support elements 25 are fixed, which in each case rest with a lower base surface 26 on corresponding first surfaces 27 of a in each case a horizontal recess 28 of the support member 17, cylindrical eccentric 29. The device 14 for adjusting the notice board 10 thus has the slide-mounted guide elements 19, the hydraulic cylinder 15 of the hydraulic lifting unit, the cylindrical support elements 25 and the cylindrical eccentric 29. Of course, the guide track 3 may be formed without such a base plate 24 or without a similar intermediate element. In this case, the device 14 for changing the notice 10 of the book block 100 directly attacks the guide track 3.

Im Bereich der als Blockeinführstation ausgebildeten Bearbeitungsstation 5 (Fig. 1) ist ein an einer der Stützen 8 des Maschinengestells 7 befestigter Ruhe-/Rütteltisch 30 angeordnet (Fig. 3). Dieser Ruhe-/Rütteltisch 30 besitzt eine plane, horizontal angeordnete Fläche 34 zur temporären Aufnahme des Rückenbereichs der Buchblocks 100 und damit zur Einstellung des Aushangs 10. In Fig. 3 ist nur eine Transportklammer 11 dargestellt. In dieser Transportklammer 11 ist der Buchblock 100 in üblicher Art und Weise gehalten, wobei der Aushang 10 in Richtung einer der hier nicht gezeigten Bearbeitungsstationen 5 nach unten aus der Transportklammer 11, deren Unterkante 11a überragend herausragt und auf der Fläche 34 des Ruhe-/Rütteltischs 30 aufliegt.In the area of the processing station 5 (FIG. Fig. 1 ) is a mounted on one of the supports 8 of the machine frame 7 resting / vibrating table 30 arranged ( Fig. 3 ). This resting / vibrating table 30 has a flat, horizontally arranged surface 34 for temporary accommodation of the back portion of the book block 100 and thus for setting the notice 10. In Fig. 3 only one transport clamp 11 is shown. In this transport bracket 11 of the book block 100 is held in a conventional manner, the notice 10 in the direction of one of the processing stations 5, not shown here down from the transport clamp 11, the lower edge 11a protrudes outstanding and on the surface 34 of the rest / Rütteltischs 30 rests.

Zur Veränderung des Aushangs 10 wird zunächst die Grundplatte 24 mit der geschlossenen Führungsbahn 3 sowie den Stützelementen 25 mittels der hydraulischen Hubeinheit der Einrichtung 14, d.h. mittels der Hydraulikzylinder 15, angehoben. Die Hydraulikzylinder 15 haben beispielsweise einen maximalen Hub von ca. 16 mm und werden von der Maschinensteuerung 6 (Fig. 1) sowie einer nicht dargestellten steuerbaren Hydraulikpumpe in üblicher Weise betätigt und zunächst bis zum maximalen Hub ausgefahren. Damit werden gleichzeitig auch die unteren Grundflächen 26 der Stützelemente 25 von den jeweils korrespondierenden ersten Flächen 27 des Exzenters 29 abgehoben. Danach werden die Exzenter 29 manuell oder automatisch in eine gewünschte Position verstellt. Anschliessend wird die Grundplatte 24 und damit auch die Führungsbahn 3 mittels der Hydraulikzylinder 15 wieder abgesenkt, bis die unteren Grundflächen 26 der Stützelemente 25 erneut, aber nunmehr auf einer anderen, entsprechend der erforderlichen Veränderung des Aushangs 10 ausgewählten, korrespondierenden zweiten Fläche 27' des Exzenters 29 aufliegen. Durch ein entsprechendes Verdrehen der Exzenter 29 lassen sich zumindest drei Höhenniveaus auswählen und einstellen, nämlich ein der Ausgangsstellung entsprechendes erstes Höhenniveau, ein zweites Höhenniveau, welches beispielsweise einen Aushang 10 der Buchblocks 100 von 11 mm bewirkt, und ein drittes Höhenniveau, welches beispielsweise einen Aushang 10 von 15 mm bewirkt. Bei dieser endlagenbezogenen Einstellung des Aushangs 10 sorgen die Führungselemente 19 für eine optimal geführte Bewegung der Grundplatte 24, so dass die erwünschte Ausrichtung der geschlossenen Führungsbahn 3 zuverlässig erhalten bleibt.To change the notice 10, the base plate 24 with the closed guide track 3 and the support elements 25 by means of the hydraulic lifting unit of the device 14, ie by means of the hydraulic cylinder 15, first raised. The hydraulic cylinders 15 have, for example, a maximum stroke of about 16 mm and are from the machine control 6 ( Fig. 1 ) and a controllable hydraulic pump, not shown, operated in a conventional manner and initially extended to the maximum stroke. Thus, at the same time the lower base surfaces 26 of the support elements 25 are lifted from the respective corresponding first surfaces 27 of the eccentric 29. Thereafter, the eccentric 29 manually or automatically adjusted to a desired position. Subsequently, the base plate 24 and thus also the guide track 3 by means of the hydraulic cylinder 15 is lowered again until the lower base surfaces 26 of the support elements 25 again, but now on another, according to the required change of the notice 10 selected, corresponding second surface 27 'of the eccentric 29 rest. By a corresponding rotation of the eccentric 29 can be at least three height levels select and set, namely a starting position corresponding first height level, a second height level, for example, a notice 10 of the book block 100 of 11 mm causes, and a third height level, which, for example, a notice 10 of 15 mm causes. In this end position-related adjustment of the notice 10, the guide elements 19 ensure an optimally guided movement of the base plate 24, so that the desired alignment of the closed guide track 3 is reliably maintained.

Mittels der jeweiligen Führungsanordnung 35 wird die Höhenlage der Transportklammern 11, 12, 13 bzw. die Höhenlage von deren jeweiliger Unterkante 11a, 12a, 13a gegenüber dem feststehenden Ruhe-/Rütteltisch 30 verstellt. Auf diese Weise können die Unterkanten 11 a, 12a, 13a der Transportklammern 11, 12, 13 in mehreren parallel zur geschlossenen Führungsbahn 3 verlaufenden, ersten Ebenen 38 des Klebebinders 1 positioniert werden. Ebenso kann die geschlossenen Führungsbahn 3 des Klebebinders 1 in mehreren parallel zueinander verlaufenden zweiten Ebenen 40 positioniert werden. Ein danach in die jeweilige Transportklammer 11, 12, 13 aufgenommener Buchblock 100 steht mit seinem Rückenbereich auf der Fläche 34 des Ruhe-/Rütteltischs 30 auf und besitzt somit nach dem Schließen der jeweiligen Transportklammer 11, 12, 13 einen entsprechend Bedarf eingestellten Aushang 10. Die ausgewählte Einstellung des Aushangs 10 wird durch eine jeweils zwischen dem Tragelement 17 und den Führungselementen 19 wirkende Klemmeinheit 36 fixiert.By means of the respective guide arrangement 35, the height position of the transporting clamps 11, 12, 13 or the height position of their respective lower edge 11a, 12a, 13a relative to the stationary resting / vibrating table 30 is adjusted. In this way, the lower edges 11 a, 12 a, 13 a of the transport clamps 11, 12, 13 in a plurality of parallel to the closed guideway 3 extending, first levels 38 of the perfect binder 1 can be positioned. Likewise, the closed guideway 3 of the perfect binder 1 can be positioned in a plurality of mutually parallel second planes 40. A thereafter in the respective transport bracket 11, 12, 13 recorded book block 100 is with his back on the surface 34 of the rest / vibrating table 30 and thus has after closing the respective transport clamp 11, 12, 13 a corresponding need set notice 10th The selected setting of the notice board 10 is fixed by a respective clamping unit 36 acting between the support element 17 and the guide elements 19.

Zudem ist in Fig. 4 mit der ersten Transportklammer 11 ebenfalls lediglich eine der drei Transportklammern 11, 12, 13 gezeigt. Der in der Transportklammer 11 aufgenommene und mit dieser geförderte Buchblock 100 weist einen aus der Transportklammer 11 in Richtung der als Rückenfräse ausgebildeten Bearbeitungsstation 5 überstehenden Aushang 10 auf. Der die Unterkante 11a der Transportklammer 11 überragende Aushang 10 wird mit der Rückenfräse mechanisch bearbeitet und dabei aufgerauht, so dass dieser Rückenbereich des bis dahin noch losen Buchblocks in einer nicht näher dargestellten, als Leimauftragsstation ausgebildeten und weiter stromabwärts angeordneten Bearbeitungsstation 5 ausreichend Klebstoff zum Verbinden der Falzbogen und/oder Einzelblätter zu einem gebundenen Buchblock 100 und zum anschliessenden Anbringen eines Umschlags oder eines Fälzelstreifen aufnehmen kann (nicht dargestellt). Schliesslich besitzt das Maschinengestell 7 mehrere hohle Stützen 8 mit Füßen 9. Fig. 4 shows a schematic side view of an alternative inventive adhesive binder 1 from the direction of arrow IV in Fig. 1 In contrast, in contrast, the machine frame 7 of the perfect binder 1 is shown and with a back cutter a single of the processing stations 5 is shown explicitly. Moreover, in Fig. 4 with the first transport bracket 11 also only one of the three transport brackets 11, 12, 13 shown. The recorded in the transport clamp 11 and funded with this book block 100 has a from the transport bracket 11 in the direction of the backbreaker designed as a processing station 5 overhanging notice 10. The lower edge 11a of the transport bracket 11 towering overhang 10 is mechanically processed with the back milling machine and roughened so that this back area of the hitherto loose book block in a non-illustrated, designed as a glue application station and further downstream processing station 5 sufficient adhesive for connecting the Fold sheet and / or single sheets to a bound book block 100 and for subsequent attachment of an envelope or a Fälzelstreifen record (not shown). Finally, the machine frame 7 has a plurality of hollow supports 8 with feet 9.

Die Einrichtung 14 zum Verändern des Aushangs 10 der Buchblocks 100 ist hierbei ebenfalls zwischen dem Maschinengestell 7 und der die geschlossene Führungsbahn 3 tragenden Grundplatte 24 angeordnet und weist im Wesentlichen mindestens ein stufenlos verstellbares Stellelement 37, bevorzugt jedoch mehrere Stellelemente 37 sowie eine Anzahl von Linearführungen 16 auf, welche beispielsweise in den hohlen Stützen 8 des Maschinengestells 7 vertikal verstellbar angeordnet und jeweils an der die Führungsbahn 3 tragenden Grundplatte 24 befestigt sind. Nach einer Verstellung des Aushangs 10 befinden sich die Unterkanten 11a, 12a, 13a der Transportklammern 11, 12, 13 jeweils in einer anderen ersten Ebene 38 und die Führungsbahn 3 jeweils in einer dementsprechenden zweiten Ebene 40, d.h. parallel und vertikal verschoben zur feststehenden Ebene der Bearbeitungsstationen 5. Zum Verändern des Aushangs 10 ist auch bei diesem Ausführungsbeispiel ein hier nicht gezeigter, am Maschinengestell befestigter Ruhe-/Rütteltisch 30 angeordnet. Der Aushang 10 variiert in dieser beschriebenen Ausführungsform im Bereich von 11 bis 15 mm stufenlos. Es ist somit bei dieser Ausführungsform nur eine zentrale Verstellung der Unterkanten 11a, 12a, 13a der Transportklammern 11, 12, 13 und der Führungsbahn 3 in der Vertikalen durch die Einrichtung 14 notwendig. Alle Bearbeitungsstationen 5 bleiben unverändert an ihrer optimalen Position stehen.The device 14 for changing the notice board 10 of the book block 100 is here also arranged between the machine frame 7 and the closed guideway 3 supporting base plate 24 and has substantially at least one continuously variable actuator 37, but preferably a plurality of actuators 37 and a number of linear guides 16th on, which are arranged vertically adjustable, for example, in the hollow supports 8 of the machine frame 7 and are each secured to the guide track 3 supporting base plate 24. After an adjustment of the notice board 10, the lower edges 11a, 12a, 13a of the transporting clamps 11, 12, 13 are in each case in a different first plane 38 and the guide track 3 respectively in a corresponding second plane 40, i. parallel and vertically shifted to the fixed plane of the processing stations 5. To change the notice board 10 is also not shown in this embodiment, fixed to the machine frame resting / vibrating table 30 is arranged. The notice board 10 in this described embodiment varies continuously in the range of 11 to 15 mm. Thus, in this embodiment, only a central adjustment of the lower edges 11a, 12a, 13a of the transporting clamps 11, 12, 13 and the guide track 3 in the vertical direction through the device 14 is necessary. All processing stations 5 remain unchanged at their optimum position.

Auch in diesem Ausführungsbeispiel erfolgt die Verstellung der geschlossenen Führungsbahn 3 mittels einer hier nicht dargestellten hydraulischen Hubeinheit. Die Linearführungen 16 sichern eine exakte, positionsgenaue vertikale Verstellung der Unterkanten 11 a, 12a, 13a der Transportklammern 11, 12, 13 und der Führungsbahn 3 mit der erforderlichen Genauigkeit von zumindest 0,1 mm. Ein üblicher, beispielsweise zwischen der Grundplatte und dem Maschinengestell angeordneter Wegmess-Sensor 39 gibt der Maschinensteuerung 6 (Fig. 1) und dem Maschinenführer eine Rückmeldung zum jeweils aktuellen Wert des realisierten Aushangs 10.Also in this embodiment, the adjustment of the closed guide track 3 by means of a hydraulic lifting unit, not shown here takes place. The linear guides 16 ensure an exact, positionally accurate vertical adjustment of the lower edges 11 a, 12 a, 13 a of the transport clamps 11, 12, 13 and the guideway 3 with the required accuracy of at least 0.1 mm. A conventional position measuring sensor 39 arranged, for example, between the base plate and the machine frame gives the machine control 6 (FIG. Fig. 1 ) and the machine operator feedback to the current value of the realized notice 10.

Alternativ dazu kann auch an jeder Transportklammer 11, 12, 13 eine Einrichtung 14 zum Verändern des Aushangs 10 der Buchblocks 100 angeordnet sein, welche mit einer Maschinensteuerung 6 des Klebebinders verbunden ist. Bei einer solchen, nicht dargestellten Lösung können die Einrichtungen 14 mit der Maschinensteuerung 6 entweder gemeinsam oder separat angesteuert werden.Alternatively, a device 14 for changing the notice board 10 of the book block 100 can also be arranged on each transporting clip 11, 12, 13, which is connected to a machine control 6 of the perfect binder. In such a solution, not shown, the devices 14 can be controlled with the machine control 6 either together or separately.
