Description

Die vorliegende Erfindung betrifft eine Buchbindereimaschine mit einer Vorrichtung zum Fügen von Zusatzteilen wie Fälzel, Hinterklebepapier o. dgl. am Buchblockrücken gemäß dem Oberbegriff nach Anspruch 1.The present invention relates to a bookbinding machine with a device for joining additional parts such as Fälzel, Hinterklebepapier o. The like. At the book block back according to the preamble of claim 1.

Zur Formstabilisierung klebegebundener, fadengesiegelter oder fadengehefteter Buchblocks werden im Klebebinder Fälzelstreifen bzw. in der Buchfertigungsstraße Gazestreifen und/oder Hinterklebestreifen auf den Buchblockrücken geklebt. Dazu sind Vorrichtungen bekannt, die über eine Transporteinrichtung verfügen, welche die Buchblöcke in vertikaler Ausrichtung mit entweder nach oben oder nach unten weisendem Rücken entweder kontinuierlich oder intermittierend zu den verschiedenen Bearbeitungsstationen führen.To stabilize the shape of adhesive-bound, thread-sealed or thread-stitched book blocks, felts strips or gauze strips and / or backing strips are glued to the book block back in the perfect binder. For this purpose, devices are known which have a transport device which guide the book blocks in vertical alignment with either upwardly or downwardly facing spine either continuously or intermittently to the various processing stations.

Des weiteren umfassen diese Vorrichtungen wenigstens eine Bearbeitungsstation, welche das Material von einem Vorrat, insbesondere einer Rolle abzieht und abhängig vom Format des Produktes in einer ersten Position (Schneideposition) auf eine gewünschte Länge und Breite zuschneidet und mithilfe einer Transportplatte in eine zweite Position überführt und dort auf den zuvor mit Klebstoff vorbereiteten Buchblockrücken auflegt. Für einen sicheren Transport des Materials von der ersten in die zweite Position ist die Transportplatte als Saugplatte oder Saugtisch ausgebildet und zur Unterdruckversorgung durch eine Saugleitung mit einer Vakuumpumpe verbunden. Die Saugleitung beinhaltet ein schaltbares Ventil, welches in der zweiten Position der Transportplatte diese von der Unterdruckversorgung trennt. Gleichzeitig wird der Materialstreifen, unterstützt durch kurzzeitiges Beaufschlagen der Transportplatte mit Druckluft, auf den mit Klebstoff versehenen Buchblockrücken abgelegt.Furthermore, these devices comprise at least one processing station, which extracts the material from a supply, in particular a roll and tailed depending on the format of the product in a first position (cutting position) to a desired length and width and using a transport plate transferred to a second position and there hangs up on previously prepared with adhesive book block spine. For a secure transport of the material from the first to the second position, the transport plate is designed as a suction plate or suction table and connected to the vacuum supply through a suction line with a vacuum pump. The suction line includes a switchable valve, which separates in the second position of the transport plate from the vacuum supply. At the same time, the material strip, supported by brief application of compressed air to the transport plate, is deposited on the adhesive backed book block spine.

In automatisierten Anlagen wird das Vorhandensein eines Zusatzteiles an der Saugplatte bzw. auf dem Buchblockrücken durch einen Sensor im Sinne einer Anwesenheitskontrolle erfasst. Dazu wird entweder der Druck in der Saugleitung mit einem Vakuumwächter überwacht oder der noch nicht angelegte Überstand des bereits an dem Buchblockrücken gefügten Materialstreifens am Buchblockrücken mit einem optischen Sensor, meist einer Lichtschranke erfasst, wie dies bspw. bei mit Fälzelstation ausgerüsteten Klebebindern der Familie KM 473 der Fall ist.In automated systems, the presence of an additional part on the suction plate or on the book block back is detected by a sensor in the sense of a presence check. For this purpose, either the pressure in the suction line is monitored with a vacuum monitor or not yet applied supernatant of the already attached to the book block back strip of material on the book block back with an optical sensor, usually a light barrier detected, such as in. Equipped with Fälzelstation perfect binder family KM 473 the case is.

Die zur Bereitstellung der Saugluft eingesetzten Vakuumpumpen erzeugen bei einem kleinen Volumenstrom eine große Druckdifferenz. Formatabhängig decken die Materialstreifen nur einen Teil der Saugöffnungen in der Transportplatte ab. An den nicht durch den Materialstreifen abgedeckten Saugöffnungen wird Luft angesaugt, wodurch der Unterdruck an den durch den Materialstreifen abgedeckten und den Materialstreifen haltenden Saugöffnungen reduziert wird. Dadurch reduziert sich zum einen das Haltevermögen der Transportplatte. Darüber hinaus verändert sich so der Unterdruck derart, dass kein Arbeitsbereich des Vakuumwächters gefunden werden kann, mit dem dieser für alle Formatbereiche sicher das Anliegen eines Materialstreifens feststellen kann. Um den vollen Unterdruck an denjenigen Saugöffnungen zu erhalten, die den Materialstreifen fixieren, werden die übrigen Saugöffnungen einzeln oder zu Gruppen zusammengefasst beim Rüstvorgang manuell abgeklebt oder durch manuell zu betätigende Ventile von der Saugleitung getrennt. Beide Vorgehensweisen sind aufwendig und fehleranfällig, wodurch sich die Verfügbarkeit der Vorrichtung stark reduziert.The vacuum pumps used to provide the suction air generate a large pressure difference at a small volume flow. Depending on the format, the material strips only cover part of the suction openings in the transport plate. At the suction not covered by the material strip suction air is sucked, whereby the negative pressure at the covered by the strip of material and the material strip holding suction ports is reduced. This reduces the holding capacity of the transport plate on the one hand. In addition, the negative pressure changes in such a way that no working range of the vacuum guard can be found, with which this can safely determine the presence of a material strip for all format ranges. In order to obtain the full negative pressure at those suction openings which fix the strip of material, the remaining suction openings are combined individually or in groups during the setting process manually taped or separated by manually operated valves from the suction line. Both approaches are complex and susceptible to errors, which greatly reduces the availability of the device.

Aus EP2324970A1 ist ein Roboter mit Flächensauggreifer zur Handhabung von Werkstücken mittels Vakuum bekannt, welcher eine Saugplatte aufweist. Diese Saugplatte umfasst einen Deckel mit Befestigungsflansch und eine Saugöffnungen aufweisende Bodenplatte, in deren Ecken Öffnungen angeordnet sind, welche der Aufnahme von Sensoren dienen können. Ein solcher Flächensauggreifer ist nicht zur Handhabung von Werkstücken geeignet, welche nicht die gesamte Bodenplatte abdecken, ohne die nicht vom Transportgut bedeckten Öffnungen aufwendig zu verschließen.Out EP2324970A1 is a robot with surface suction for handling workpieces by vacuum known, which has a suction plate. This suction plate comprises a cover with mounting flange and a suction plate having bottom plate in the corners openings are arranged, which can serve to receive sensors. Such a surface suction is not suitable for handling workpieces, which do not cover the entire bottom plate without closing the not covered by the cargo openings costly.

Aus DE 102006044156 A1 sind eine Vorrichtung und ein Verfahren bekannt, wobei die Saugöffnungen des Fälzeltisches (der Transportplatte) einzeln oder zu Gruppen zusammengefasst durch jeweils einen Ejektor mit Unterdruck versorgt werden. Durch entsprechende Ventile in der Druckluftversorgung dieser Ejektoren können einzelne Saugöffnungen bzw. Gruppen von Saugöffnungen aktiviert oder deaktiviert werden. Die Ejektoren sind dabei bevorzugt direkt an den Saugöffnungen in der Transportplatte angeordnet oder Bestandteil der Transportplatte. Durch an das Format des Materialstreifens angepasstes Aktivieren bzw. Deaktivieren der Ejektoren und die kurzen Saugleitungen kann der Energiebedarf reduziert werden. Je feiner die Auflösung sein soll, desto mehr Ejektoren und diesen zugeordnete Ventile sind erforderlich. Damit erhöht sich wiederum der Aufwand für das Rüsten sowie die Komplexität der Vorrichtung. Durch Integration der Ejektoren und der damit erforderlichen Druckluftanschlüsse in die Transportplatte erhöht sich die bewegte Masse, wodurch aufgrund der Maschinendynamik die mechanische Leistung der Vorrichtung begrenzt ist.Out DE 102006044156 A1 a device and a method are known, wherein the suction openings of Fälzeltisches (the transport plate) individually or in groups summarized are supplied by a respective ejector with negative pressure. By means of appropriate valves in the compressed air supply of these ejectors, individual suction openings or groups of suction openings can be activated or deactivated. The ejectors are preferably arranged directly on the suction openings in the transport plate or part of the transport plate. By activating or deactivating the ejectors and the short suction lines adapted to the format of the material strip, the energy requirement can be reduced. The finer the resolution should be, the more ejectors and associated valves are required. This in turn increases the effort for setup and the complexity of the device. By integrating the ejectors and the thus required compressed air connections in the transport plate increases the moving mass, which due to the machine dynamics, the mechanical performance of the device is limited.

Der Erfindung liegt damit die Aufgabe zugrunde, eine Vorrichtung zum Fügen eines Zusatzteiles wie einem Fälzel, Hinterklebepapier o. dgl. mit einem Blattstapel wie beispielsweise einem Buchblock zu schaffen, welche die genannten Nachteile bekannter Vorrichtungen beseitigt.The invention is thus based on the object to provide a device for joining an additional part such as a Fälzel, Hinterklebepapier o. The like. With a stack of sheets such as a book block, which eliminates the disadvantages of known devices.

Diese Aufgabe wird gelöst durch eine Vorrichtung nach Anspruch 1. Die abhängigen Ansprüche definieren bevorzugte Ausführungsformen der erfindungsgemäßen Vorrichtung.This object is achieved by a device according to claim 1. The dependent claims define preferred embodiments of the device according to the invention.

Nach der erfindungsgemäßen Vorrichtung ist die Transportplatte einer Hinterklebestation, insbesondere einer Fälzelstation im Klebebinder oder einer Kapitalstation einer Buchfertigungsstraße als Saugplatte gestaltet. Die Vorrichtung umfasst darüber hinaus ein Sensorsystem, um das Vorhandensein eines Zusatzmaterials an der Saugplatte zu erfassen, das unabhängig von der den Materialstreifen an der Transportplatte haltenden Saugluft arbeitet. Erfindungsgemäß umfasst das Sensorsystem dazu eine separate Öffnung in der Saugplatte, deren Versorgung mit Unterdruck durch ein Luftführungssystem erfolgt, das getrennt ist von einem weiteren Luftführungssystem, welches für das Fixieren des Zusatzmaterial an der Transportplatte genutzt wird. Dazu umfasst das Luftführungssystem des Sensorsystems dazu eine eigene den erforderlichen Unterdruck bereitstellenden Einrichtung, welche durch eine Unterdruckleitung mit der separaten Öffnung in der Saugplatte verbunden ist. Vorzugsweise wird der Druck in dieser Unterdruckleitung durch einen Vakuumwächter überwacht, der mit einer Steuerung verbunden ist, welche das Sensorsignal verarbeitet, vorzugsweise der Steuerung des Klebebinders bzw. der Buchfertigungsstraße.After the device according to the invention, the transport plate of a Hinterklebestation, especially a Fälzelstation in perfect binder or a capital station of a book production line is designed as a suction plate. The apparatus further includes a sensor system for detecting the presence of a filler material on the suction plate that operates independently of the suction air holding the strip of material on the transport plate. According to the invention, the sensor system for this purpose comprises a separate opening in the suction plate, the supply of negative pressure by an air duct system, which is separated from another air duct system, which is used for fixing the additional material to the transport plate. For this purpose, the air guidance system of the sensor system to this includes its own the necessary negative pressure providing device which is connected by a vacuum line to the separate opening in the suction plate. Preferably, the pressure in this vacuum line is monitored by a vacuum monitor which is connected to a controller which processes the sensor signal, preferably the control of the perfect binder or book production line.

Aufgrund er getrennten Luftführungssysteme wird die vom Sensor aufgenommene Messgröße nicht durch Saugöffnungen beeinflusst, welche nicht oder nur teilweise von dem zu fügenden Zusatzteiles abgedeckt oder manuell abgeklebt und nicht von der Saugleitung getrennt sind. Vorzugweise befindet sich diese separate Öffnung in demjenigen Bereich der Saugplatte, der durch den Materialstreifen unabhängig von dessen Format bedeckt wird. Die Funktion des Sensorsystem bleibt somit von dem zu verarbeitenden Format auch ohne Rüsten unbeeinflusst. Darüber hinaus ermöglichen die getrennten Luftführungssysteme eine unabhängige Auslegung der beiden Luftführungssysteme und insbesondere deren Verdichter und damit eine Optimierung hinsichtlich der Hauptfunktion. Vorzugsweise wird für das Fixieren des Zusatzteiles ein Verdichter eingesetzt, welcher einen ausreichend großen Volumenstrom zur Verfügung stellt, sodass die Haltefunktion sichergestellt ist, ohne dazu nicht vom Zusatzteil bedeckte Saugöffnungen zu verschließen oder von der Saugluft zu trennen. Ein formatabhängiges Rüsten der Saugplatte kann so entfallen. Vorzugsweise ist der Kompressor ein Seitenkanalverdichter, dessen Saugleistung abhängig von dem Format und den Materialeigenschaften des Zusatzteiles sowie dem Vorhandensein eines zu hinterklebenden Buchblockes von der Steuerung des Klebebinders bzw. der Buchfertigungsstraße durch einstellen einer geeigneten Drehzahl gesteuert wird, sodass der Energiebedarf produktabhängig minimiert werden kann.Due to it separate air ducting systems, the measured variable recorded by the sensor is not influenced by suction openings which are not or only partially covered by the additional part to be joined or manually taped and not separated from the suction line. Preferably, this separate opening is in that area of the suction plate which is covered by the strip of material, regardless of its format. The function of the sensor system thus remains unaffected by the format to be processed even without setup. In addition, the separate air ducts allow independent design of the two air duct systems and in particular their compressor and thus an optimization in terms of the main function. Preferably, a compressor is used for fixing the additional part, which provides a sufficiently large volume flow, so that the holding function is ensured, without being closed by the additional part covered suction openings or separate from the suction air. A format-dependent setup of the suction plate can be omitted. Preferably, the compressor is a side channel compressor, the suction power is controlled depending on the format and the material properties of the additional part and the presence of a book block to be backed by the control of Klebebinders or book production line by setting a suitable speed, so that the energy requirement can be minimized depending on the product.

Das Lösen den Materialstreifens von der Saugplatte bei bzw. nach dem Fügen an den Buchrücken wird durch kurzzeitiges Beaufschlagen der Saugplatte mit Druckluft unterstützt. Vorzugweise wird dazu Druckluft in die Saugleitung unmittelbar an der oder direkt in die Saugplatte eingeleitet, wodurch die Verluste insbesondere saugseitig klein gehalten werden.The release of the strip of material from the suction plate during or after the joining to the spine is supported by briefly applying the suction plate with compressed air. Preferably, compressed air is introduced into the suction line directly on or directly into the suction plate, whereby the losses are kept small in particular suction side.

Die Verfügbarkeit der erfindungsgemäßen Vorrichtung ist im Vergleich zu Vorrichtungen gemäß dem oben beschriebenen Stand der Technik deutlich verbessert, da auf das Rüsten der Saugplatte ebenso verzichtet wird wie auf Ventile in der Saugleitung oder dem Sensorsystem, was darüber hinaus den Verschleiß sowie die Fehlerwahrscheinlichkeit reduziert.

The availability of the device according to the invention is significantly improved compared to devices according to the above-described prior art, since it is dispensed with the setup of the suction plate as well as valves in the suction line or the sensor system, which also reduces the wear and the probability of error.

Diese Überführungseinheit (1) ist wie in Figur 3 dargestellt derart in einem Paar Schwenkarme (37) gelagert, dass die räumliche Orientierung der Saugplatte (2) während des Schwenkens aus der Bereitstellungsposition (25) auf den Buchblockrücken (27) im Wesentlichen unverändert horizontal beibehalten wird. Dabei fixiert die Saugplatte (2) das Zusatzteil (23) durch Saugluft, die durch zahlreiche Saugöffnungen (6) durch die Bodenplatte (4) tritt (vgl. Fig. 4a). Um diese Saugöffnungen (6) mit Saugluft zu versorgen, ist die Saugplatte (2) durch eine Saugluftleitung (8) mit einem Kompressor (36), vorzugsweise einem Seitenkanalverdichter verbunden. Die Saugplatte (2) ist als Hohlkörper ausgebildet, der sich vorzugsweise aus einer die Saugöffnungen (6 und 7) beinhaltenden Bodenplatte (4) und einem die Lager (21) und Saug- und Druckluftleitungen (8, 15, 10) aufnehmendem Deckel (5) durch eine Verschraubung (20) verbunden zusammensetzt.This transfer unit (1) is as in FIG. 3 shown supported in a pair of pivot arms (37) such that the spatial orientation of the suction plate (2) is maintained substantially unchanged horizontally during pivoting from the staging position (25) to the book block spine (27). In this case, the suction plate (2) fixes the additional part (23) by suction air, which passes through numerous suction openings (6) through the bottom plate (4) (see. Fig. 4a ). To supply these suction openings (6) with suction air, the suction plate (2) through a suction air line (8) with a compressor (36), preferably a side channel compressor is connected.
