Description
Die Erfindung betrifft ein Verfahren zum Ueberwachen des Leimauftrages auf einen Rücken eines in einer Buchbindemaschine bearbeiteten und durch Kleben gebundenen Buchblockes durch Messen der Leimauftragsdicke.The invention relates to a method for monitoring the glue application on a back one in a bookbinding machine edited and bound by book block Measure the glue application thickness.
Das Beleimen von Buchblöcken in Buchbindemaschinen ist seit langem bekannt. Der Leim wird auf den Buchrücken als Schicht mit Leimrollen aufgetragen. Für die Qualität und die Haltbarkeit der aus den Buchblöcken hergestellten Druckprodukten ist es nun wesentlich, dass der Leim gleichmässig und überall mit der optimalen Schichtdicke aufgetragen wird. Zur Kontrolle des Leimauftrages wurden bisher beleimte Buchblöcke von Auge kontrolliert und dazu auch aufgeschnitten. Dies ist jedoch vergleichsweise aufwendig und kleinere Schichtdickenunterschiede oder Fehler können von Auge nicht oder erst spät festgestellt werden. The gluing of book blocks in bookbinding machines has been around since known for a long time. The glue is applied to the spine as a layer applied with glue rolls. For quality and durability of the printed products made from the book blocks It is now essential that the glue be evenly and everywhere with the optimal layer thickness is applied. To control the Previously glued book blocks were checked by eye and also cut open. However, this is comparative complex and smaller differences in layer thickness or errors can not be noticed by the eye or only late become.
Im übrigen wird auf das Buch "Klebebinden" des Verlages Beruf + Schule, Itzehoe verwiesen.For the rest, the book "Perfect Binding" by the publisher becomes a profession + School, Itzehoe referenced.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem eine einfachere und zuverlässigere Ueberwachung des Leimauftrages möglich ist.The invention is based on the object of a method create with which a simpler and more reliable monitoring of the glue application is possible.
Diese Aufgabe ist nach dem kennzeichnenden Teil des Patentanspruches
1 gelöst.This object is according to the characterizing part of the
Bei einer erfindungsgemässen Vorrichtung werden die Buchblöcke an einem Sender und einem diesem zugeordneten Empfänger, die zusammenwirkend als Messwertgeber, quer zum Förderpfad eines Buchblockes einen Messbereich bildend, in der Buchbindemaschine angeordnet sind, vorbeigeführt, derart, dass zumindest die an dem Buchblockrücken aufgetragene Leimschicht den Messbereich teilweise durchsetzt.In a device according to the invention, the book blocks on a transmitter and a receiver assigned to it interacting as a transmitter, across the funding path of a Book block forming a measuring range in the book binding machine are arranged, passed such that at least the glue layer applied to the back of the book block covers the measuring area partially enforced.
Der durch den Buchblockrücken bzw. die Leimschicht abgedeckte oder der nicht abgedeckte Sendebereich des Messbereichs kann an einen Sensor zurückgekoppelt und ausgewertet werden. Der abgedeckte Mess- resp. Sendebereich ist abhängig von der Leimdicke.The one covered by the back of the book block or the layer of glue or the uncovered transmission range of the measuring range can be fed back to a sensor and evaluated. The covered measuring resp. The transmission range depends on the thickness of the glue.
Die erfindungsgemässe Vorrichtung erlaubt eine automatische und eine kontinuierliche Ueberwachung des Leimauftrages, so-dass auch Abweichungen, beispielsweise Toleranzabweichungen, unbeleimte Bereiche oder Einschlüsse feststellbar sind.The device according to the invention allows automatic and continuous monitoring of the glue application, so that also deviations, for example tolerance deviations, areas without glue or inclusions can be identified.
Da Sender und Empfänger seitlich neben dem Förderpfad der Buchblöcke angeordnet sind, kann eine Verschmutzung der Vorrichtung ausgeschlossen werden.Since the transmitter and receiver are located to the side of the conveyor path of the Book blocks are arranged, contamination of the device be excluded.
Eine Verlängerung des Förderpfades ist wegen der Vorrichtung nicht erforderlich, weil Sender und Empfänger problemlos unterbringbar sind. An extension of the funding path is due to the device not necessary because the transmitter and receiver can be easily accommodated are.
Eine Messung der effektiven Leimdicke ist dann besonders exakt möglich, wenn gemäss einer Weiterbildung der Erfindung der Sender und der Empfänger nach dem Leimauftrag und ein zweiter Sender und Empfänger vor dem Leimauftrag angeordnet sind. Die eine Messung erfolgt bei noch nicht beleimten Buchblock und die zweite bei beleimten Buchblock. Vorzugsweise sind beide Messanordnungen resp. Messwertgeber unter gleichen mechanischen und elektrischen Voraussetzungen installiert, so dass jeweils gleichwertige elektrische Signale zur Verfügung stehen, die verglichen werden können.A measurement of the effective glue thickness is then particularly precise possible if according to a further development of the invention the Sender and the receiver after the glue application and a second Sender and receiver are arranged before the glue application. The a measurement is made with the book block and not yet glued the second with glued book block. Both are preferred Measuring arrangements resp. Transducers under the same mechanical and electrical requirements installed so that equivalent electrical signals are available, that can be compared.
Insbesondere kann der Unterschied der beiden Messsignale dazu verwendet werden, um die effektive Leimschicht bzw. Leimdicke zu messen. Es ist aber auch möglich, lediglich eine Aussage zu treffen ob der Leimauftrag in einem vorbestimmten Bereich liegt oder nicht.In particular, the difference between the two measurement signals can used to determine the effective glue layer or glue thickness to eat. But it is also possible to just make a statement hit whether the glue application in a predetermined range lies or not.
Eine besonders genaue Messung ergibt sich dann, wenn die Vorrichtung gemäss einer Weiterausgestaltung der Erfindung einen Sender mit einem balkenförmigen Sendefenster aufweist, das quer zur Laufrichtung des Buchrückens gesehen geneigt ist.A particularly accurate measurement results when the device according to a further embodiment of the invention Has transmitter with a bar-shaped transmission window, the seen transversely to the direction of the spine.
Das balkenförmige Sendefenster kann vorzugsweise durch ein im Querschnitt balkenförmiges Lichtfaserkabel gebildet sein, das der Neigung entsprechend eine hohe Faserdichte quer zur Förderrichtung aufweist.The bar-shaped transmission window can preferably by an im Cross-section beam-shaped fiber optic cable to be formed corresponding to the inclination, a high fiber density across the conveying direction having.

Die in Figur 1 teilweise gezeigte Buchbindemaschine 2 weist
ein stationäres und hier nur andeutungsweise veranschaulichtes
Maschinengestell 2a auf, in dem an Führungsschienen 16 in einer
Reihe hintereinander Zangen 11 in Richtung des Pfeiles 10
bewegbar sind. Mit den Zangen 11 werden Buchblöcke 1 nacheinander
den verschiedenen Bearbeitungsbereichen zugeführt. Aus
den zu Buchblöcken 1 vorerst lose zusammengetragenen Druckbogen
werden in der Buchbindemaschine 2 gebundene Druckprodukte
hergestellt. Bei dem in Figur 1 gezeigten Verarbeitungsschritt
wird auf den bspw. beschnittenen Buchrücken 4 des Buchblocks 1
eine Leimschicht 12 aufgetragen, welche den Buchblock 1 zusammenhalten
soll. Um den in Figur 1 links gezeigten nicht
beleimten Buchblock la zu beleimen, wird dieser in Richtung
des Pfeiles 10 über Rollen 15 geführt, die in einem unteren
Bereich in Leim 13 eintauchen, der in einem Leimbecken 14 vorliegt.
Die beiden Rollen 15 drehen im Uhrzeigersinn, während
eine kleinere Rolle 15a, die in der Fachsprache Spinner genannt
wird, in Gegenrichtung dreht und vom Buchrücken 4 überschüssigen
Leim abstreift. Beim Beleimen werden die Buchblöcke
1 ohne Unterbruch kontinuierlich in Richtung des Pfeiles 10
weiterbewegt.The
Zur Ueberwachung des Leimauftrages ist eine Messeinrichtung
vorgesehen, die zwei im Abstand zueinander angeordnete Messwertgeber
bzw. Messanordnungen 8 und 9 aufweist. Die Messanordnung
8 befindet sich in Transportrichtung 10 gesehen vor
dem Leimbecken 14 und die andere Messanordnung 9 nach dem
Leimbecken 14. Beide Messanordnungen 8 und 9 sind vorzugsweise
gleich ausgebildet und arbeiten nach demselben Prinzip.There is a measuring device for monitoring the glue application
provided, the two sensors arranged at a distance from each other
or measuring
Die in Figur 2 gezeigte Messanordnung 8 entspricht damit auch
der Messanordnung 9. Die Messanordnung 8 weist einen Sender 3
und einen Empfänger 5 auf, zwischen denen sich eine Luftstrekke
24 befindet, die quer zur Transportrichtung 10 verläuft.
Wie die Figur 5 zeigt, wird das Licht z.B. Infrarotlicht einer
Lichtquelle 20 in ein Lichtfaserkabel 19 oder ein anderes geeignetes
Uebertragungsmedium gekoppelt. Das vom Sender 3 abgestrahlte
Licht wird von einem Empfänger 5 empfangen und mit
einem Lichtfaserkabel 18 an ein lichtempfindliches Sensorelement
26 zurückgekoppelt. Die beiden Lichtfaserkabel 18 und 19
sowie der Sender 3 und der Empfänger 5 sind vorzugsweise identisch
ausgebildet. Sie besitzen zudem vorzugsweise einen
rechteckigen oder balkenförmigen Querschnitt und der Sender 3
als auch der Empfänger jeweils ein entsprechend balkenförmiges
Fenster 23 bzw. 27. Die Messanordnung 8 arbeitet im Einwegverfahren,
das heisst im definierten Abstand entsprechend zum
Sender 3 befindet sich der Empfänger 5, der durch das Lichtfaserkabel
18 gebildet ist. Das Lichtfaserkabel 18 dient somit
lediglich als Uebertragungselement für das empfangene Licht
und ist mechanisch an den Lichtsensor 26 angekoppelt. Der Sensor
26 wandelt das empfangene Licht in ein elektrisches Signal
um, das für den weiteren Messzweck verwendet wird.The
Wie die Figur 2 und insbesondere Figur 6 zeigen, sind die beiden
Fenster 23 und 27 genau parallel zueinander ausgerichtet
und bezüglich der Transportrichtung 10 geneigt. Der Abstand 24
ist nun so angeordnet, dass das balkenförmige Lichtbündel 6
zwischen dem Sender 3 und dem Empfänger 5 von den Buchrücken 4
einzeln durchfahren wird. Hierbei wird ein Bereich 6a des
Lichtbündels 6 vom Buchrücken 4 abgedeckt und dieser Bereich
6a gelangt entsprechend nicht zum Empfänger 5, wie dies beispielsweise
deutlich in Figur 4 gezeigt ist. Ein unterer Bereich
6b des Lichtbündels 6 befindet sich beim durchfahrenden
Buchrücken 1 unterhalb des zu beleimenden Buchrückens 4 und
wird somit vom Empfänger 5 empfangen. Ein Bereich 6a wird auch
dann abgedeckt, wenn bei der Messanordnung 8 der Buchrücken 4
nicht beleimt ist. Der abgedeckte Bereicht 6 ist hier jedoch
kleiner, als der bei der Messanordnung 9 abgedeckte Bereich,
da hier nun die aufgetragene Leimschicht 12 entsprechend der
Schichtdicke ebenfalls einen Teil des Lichtbündels abdeckt.
Die Fenster 23 und 27 sind nun so angeordnet, dass die Buchrücken
beispielsweise etwa 50 % des Lichtbündels abdecken.
Dies hat zur Folge, dass das elektrische Signal des Sensorelementes
26 entsprechend ebenfalls nur 50 % des Maximalwertes
entspricht, da bei Nichtanwesenheit eines Buchblockes 1 der
Empfänger 5 100 % des vom Sender ausgesendeten Lichtes empfängt.
Wie bereits erwähnt, sind vorzugsweise die beiden Messanordnungen
8 und 9 gleich ausgebildet. Dies hat zur Folge,
dass das elektrische Signal der Messanordnung 8 und das elektrische
Signal der Messanordnung 9 gleichwertig sind und verglichen
werden können. Wesentlich ist nun auch, dass die nicht
beleimten Buchblöcke 1 immer gleiche Signale bei der Messanordnung
8 ergeben. Die Signale bei der Messanordnung 9 sind
jedoch abhängig vom Leimauftrag und insbesondere von der
Schichtdicke A (Figur 1) der Leimschicht 12. Der Unterschied
der beiden Messsignale kann nun dazu verwendet werden, die
effektive Leimdicke zu messen. Der Unterschied der Signale
kann aber auch dazu verwendet werden, eine Aussage zu treffen,
ob der Leimauftrag in einem vorbestimmten definierten Bereich
liegt oder nicht. Denkbar sind aber auch andere Anwendungen.
Beispielsweise könnte graphisch ein Längspofil der Leimschicht
12 aufgezeichnet werden. Die erfindungsgemässe Vorrichtung
ermöglicht somit, dass jeder Leimauftrag auf einen Buchblock 1
überwacht werden kann. Fehler beim Leimauftrag, die beispielsweise
durch Verschmutzung, Staub oder Leimfäden verursacht
sein können oder die durch das Einspannen eines Buchblockes 1
(bspw. Schieflage) entstehen, können sofort festgestellt werden.As FIG. 2 and in particular FIG. 6 show, the two are
Die erwähnte Neigung der Fenster 23 und 27 ermöglicht eine
besonders präzise Messung mit Lichtfaserkabeln. Durch die Neigung
der Fenster 23 und 27 befinden sich gemäss Figur 6 im
Bereich der Leimschicht 12 mehr Lichtfasern 25 als bei einer
vertikalen Anordnung. In der Regel sind selbstverständlich
wesentlich mehr Lichtfasern 25 vorhanden als in Figur 6 gezeigt.
Das Uebertragungsmedium ist vorzugsweise ein temperaturbeständiges
Glasfaserkabel, jedoch sind auch andere Uebertragunsgmittel
denkbar.The aforementioned inclination of the
