Abstract
Description
Die Erfindung richtet sich auf ein Verfahren und eine Vorrichtung zum Entsäuern von Büchern oder dergleichen wobei das aufgeblätterte Buch über einen Gasstrom mit einem basischen oder basisch machbaren Pulver beaufschlagt wird. Eine Verfahren und eine Vorrichtung der gattungsgemäßen Art sind beispielsweise aus DE 44 36 635 C2 bekannt.The invention relates to a method and an apparatus for Deacidify books or the like being the opened book via a gas flow with a basic or basic powder is applied. A method and an apparatus of the generic type Art are known for example from DE 44 36 635 C2.
Die Säure im Papier von Büchern ist Ursache für die Zerstörung großer Buchbestände in Bibliotheken. Es wird deshalb versucht, die Säure im Papier zu neutralisieren und eine alkalische Reserve gegen zukünftige Säureangriffe aufzubauen.The acidity in the paper of books is the cause of the destruction of large ones Book holdings in libraries. It is therefore trying to find the acidity in the paper neutralize and an alkaline reserve against future acid attacks build up.
Bei einem vorbekannten Verfahren wird Diäthylzink als alkalisches Gas für die Behandlung verwendet. Dieses Verfahren hinterläßt allerdings einen unerwünschten Geruch in den Büchern sowie teilweise eine schillernde Verfärbung der Einbände. Als problematisch sind auch die hohen Temperaturen anzusehen, denen die Bücher wegen des exothermen Prozeßverlaufs ausgesetzt sind. Auch können negative Langzeitwirkungen nicht ganz ausgeschlossen werden die gegebenenfalls eine spätere Lagerung der Bücher in dunklen Räumen erforderlich machen. Darüber hinaus konnte sich dieses Verfahren auch wegen der hohen Kosten wirtschaftlich nicht durchsetzen.In a previously known method, diethyl zinc is used as an alkaline gas for used the treatment. However, this procedure leaves one unwanted smell in the books as well as an iridescent part Discoloration of the covers. The high temperatures are also problematic to watch the books because of the exothermic process are exposed. Also, negative long-term effects cannot be quite Any later storage of the books is excluded Require in dark rooms. Beyond that could not economically enforce this procedure because of the high costs.
Weiterhin gibt es sogenannte nasse Verfahren, bei welchen der alkalische Wirkstoff in einer Trägerflüssigkeit oder suspendiert und mit deren Hilfe auf die Buchseiten transportiert wird. Dabei sind FCKW-haltige Träger einerseits besonders geeignet, bilden andererseits aber unter Umweltgesichtspunkten auch ein Hauptproblem bei diesen Verfahren. Werden dementsprechend andere flüssige Trägermedien angesetzt, ist ein Feuchtigkeitsentzug unter Einsatz von Mikrowellen erforderlich, der von der Fachwelt als eine nicht erwünschte Belastung für die Bücher angesehen wird und zu Beschädigung von Metallteilen am Einband führen kann. Weitere negative Kostenfaktoren sind eine aufwendige Konstruktion wegen des niedrigen Flammpunktes in Verbindung mit der Rückgewinnung und Reinigung des Lösungsmittels sowie die erforderliche wochenlange Zwischenlagerung der behandelten Bücher. Weiterhin können die nassen Lösungsmittel nur eine begrenzte Wirkstoffmenge aufnehmen. Wenn aber die vom Papier aufgenommene Lösungsmittelmenge nicht genügend Wirkstoff enthält, wird keine ausreichende Behandlung erreicht.There are also so-called wet processes, in which the alkaline Active ingredient in a carrier liquid or suspended and with their help is transported to the book pages. CFC-containing carriers on the one hand particularly suitable, on the other hand they form from an environmental point of view also a major problem with these procedures. Be accordingly If other liquid carrier media are used, then moisture is removed using microwaves required by the professional is viewed as an undesirable burden on the books and to Damage to metal parts on the cover can result. More negative Cost factors are a complex construction because of the low Flash point in connection with the recovery and cleaning of the Solvent and the necessary weeks of interim storage treated books. Furthermore, the wet solvents can only be one absorb limited amount of active ingredient. But if the one recorded on paper Does not contain sufficient amount of solvent, will not sufficient treatment achieved.
Das eingangs erwähnte, aus der DE 44 36 635 bekannte Verfahren weist als Trockenverfahren Vorteile gegenüber den vorher beschriebenen Naßverfahren auf, ist aber gleichwohl noch mit erheblichen Nachteilen behaftet. So wird bei diesem Verfahren ein Buch einzeln befestigt und durch relativ starke Luftströmung bei einem Öffnungswinkel von ca. 165° offengehalten. Mittels eines Schwenkarms wird von unten durch Düsen Lauge bzw. Laugenanhydrid in Pulverform in das Buch eingeblasen. Danach wird in einem zweiten Arbeitsgang und in einer zweiten Maschine das Buch von der überschüssigen Pulvermenge mittels Preßluft befreit, womit eine erhebliche Beschädigungsgefahr einhergeht, und schließlich werden in einem dritten Arbeitsgang und in einer dritten Maschine die Buchseiten bedampft. Zuletzt werden die Bücher per Hand noch einmal gereinigt. Das System weist damit nicht die bei Naßverfahren auftretenden Nachteile wie Mangel an alkalischer Reserve oder Halbmond-Effekt" auf aber die Bücher werden relativ stark mechanisch beansprucht. Außerdem sind die Bücher auch einer relativ starken Handhabungsbeanspruchung unterworfen was durch die Einzelbuchbehandlung und den erforderlichen Maschinenwechsel bedingt ist. Da bei diesem Verfahren zudem nur eine subjektive Kontrolle der Menge von Basenanhydrid im Buch durchgeführt wird, kann es vorkommen daß die Bücher nach der Behandlung mit Wirkstoffpulver angereichert sind.The method mentioned at the beginning, known from DE 44 36 635, has advantages as a dry method compared to the previously described wet method, but is nevertheless still associated with considerable disadvantages. In this process, a book is attached individually and kept open by a relatively strong air flow at an opening angle of approx. 165 °. Using a swivel arm, lye or lye anhydride in powder form is blown into the book from below through nozzles. Thereafter, in a second operation and in a second machine, the excess powder is released from the book by means of compressed air, which entails a considerable risk of damage, and finally the pages of the book are steamed in a third operation and in a third machine. Finally, the books are cleaned again by hand. The system thus does not have the disadvantages that occur with wet processes, such as a lack of alkaline reserve or Half-moon effect "on but the books are subjected to a relatively high mechanical load. In addition, the books are also subjected to a relatively high handling stress, which is due to the individual book handling and the necessary machine change. Since this method also only a subjective control of the amount of base anhydride in the book is carried out, it may happen that the books are enriched with active ingredient powder after treatment.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen die eine schnelle, effektive und gleichwohl außerordentlich schonende Entsäuerung von Büchern bei kostengünstiger Ausführbarkeit ermöglicht.Proceeding from this, the object of the invention is a method and to create a device that is fast, effective and nevertheless extremely gentle deacidification of books at a lower cost Executability enables.
Diese Aufgabe wird gelöst durch ein Verfahren gemäß dem kennzeichnenden
Teil von Anspruch 1 und durch eine Vorrichtung gemäß dem kennzeichnenden
Teil von Anspruch 12.This object is achieved by a method according to the characteristic
Part of
Das erfindungsgemäße Behandlungsverfahren ist gattungsgemäß ein Trockenverfahren und vermeidet die beschriebenen Nachteile von Naßverfahren. Gegenüber anderen bekannten Trockenverfahren zeichnet sich das Verfahren dadurch aus, daß die Bücher bei der Arbeitsvorbereitung in eine Buchkassette mit einem Öffnungswinkel von 90° eingelegt und befestigt werden. Diese mehrere Bücher aufnehmende Buchkassette ist in einer Behandlungskammer angeordnet, welche nach außen hin hermetisch verschlossen ist, und in welcher eine Behandlung der Bücher in vier aufeinanderfolgenden Phasen erfolgt, ohne daß dabei eine Verlagerung der Bücher und ein Wechsel der Maschine erforderlich wäre. Als Transportmedium für das Laugenanhydrid-Pulver, z.B. MgO, wird Luft verwendet, welche gereinigt wieder in die Atmosphäre zurückgeleitet wird. Es wird somit zuverlässig vermieden daß Bedienungspersonal mit dem Wirkstoffpulver in Kontakt gelangt.The treatment method according to the invention is of the generic type a dry method and avoids the disadvantages of wet processes described. This distinguishes itself from other known drying processes Procedure characterized in that the books in the work preparation in a Book cassette inserted and fastened with an opening angle of 90 ° become. This multi-book cassette is in a treatment chamber arranged, which are hermetically sealed from the outside and in which a treatment of the books in four successive Phases takes place without relocating the books and a change of the machine would be necessary. As a transport medium for the alkali anhydride powder, e.g. MgO, air is used which is cleaned is returned to the atmosphere. It becomes reliable avoided that operating personnel come into contact with the active ingredient powder reached.
Eine Besonderheit des erfindungsgemäßen Verfahrens liegt darin daß die Bücher im Vakuum entsäuert werden vorzugsweise bei einem Druck von etwa 300 mbar. Hierdurch ist es möglich, mit einer gegenüber herkömmlichen Verfahren erheblich niedrigeren Luftströmung auszukommen und die hierdurch bedingte mechanische Belastung der Bücher drastisch zu reduzieren. Da die Bücher erfindungsgemäß mittels Umluft von zwei gegenüberliegenden Seiten durchgeblasen werden, ist es möglich, eine definierte Luftmenge durch eine exakt vorgegebene Pulvermenge zu sättigen und auf diese Weise sicherzustellen daß dem Buch nur die wirklich notwendige Pulvermenge zugeführt wird unter Berücksichtigung einer alkalischen Reserve.A special feature of the method according to the invention is that Books are deacidified in a vacuum preferably at a pressure of about 300 mbar. This makes it possible to use a conventional one Procedures to get by and the air flow significantly lower thereby drastically reducing the mechanical stress on the books. Since the books according to the invention by means of air circulation from two opposite Pages are blown through, it is possible to create a defined one Air volume to saturate with a precisely specified amount of powder and up this way to ensure that the book only the really necessary The amount of powder is supplied taking into account an alkaline reserve.

In einer nach außen hermetisch abschließbaren Behandlungskammer 21 ist
ein Bücherkassettenwagen 22 angeordnet, welcher beispielsweise zehn Bücherkassetten
23 aufnimmt, wovon in Fig. 2 jeweils nur die Außenliegenden
gezeichnet sind.In a
Der Bücherkassettenwagen 22 weist Räder 24 und eine Kupplung 25 auf,
welche zur Verbindung mit einer Antriebseinrichtung A dient, welche den
Bücherkassettenwagen 22 in der Behandlungskammer 21 periodisch hin- und
herbewegt, so daß die Buchseiten eine fächelnde Bewegung durchführen.
Hierdurch wird eine nachfolgend noch beschriebene extrem gleichmäßige
Beaufschlagung der einzelnen Buchseiten mit Wirkstoff möglich.The
Die Buchkassetten 23 umfassen Seitenwände 26, die je nach Buchstärke
einstellbar sind, welche zueinander in einem Winkel von 90° angeordnet
sind, was zu einer optimalen Auffächerung der liegend angeordneten Bücher
27 führt.The
Die Arbeitsweise einer erfindungsgemäßen Vorrichtung und das erfindungsgemäße Verfahren werden nachfolgend in Verbindung mit Fig. 4 näher erläutert: The operation of a device according to the invention and the inventive Methods are described in more detail below in connection with FIG. 4 explains:
In einer Vorbereitungsphase werden die zu behandelnden Bücher 27 in die
Bücherkassetten 23 eingelegt und am Bucheinband (Deckel) befestigt. Die
Bücherkassetten 23 sind gepolstert, so daß eine optimale Schonung der Bücher
27 gewährleistet ist. Mit Hilfe des Wagens 22 werden die Bücher 27
in die Behandlungskammer 21 gebracht. Über die Kupplung 25 wird die
Antriebseinrichtung 3 angekuppelt. Anschließend wird die Behandlungskammer
21 hermetisch geschlossen. Durch Druck auf eine Starttaste wird
eine SPS-Steuerung in Gang gesetzt.In a preparatory phase, the books to be treated 27 are in the
In einer ersten Behandlungsphase werden die Bücher 27 von Staub und
losen Partikeln befreit. Hierzu werden die Umluftmotoren 2, der Horizontalmotor
3 für den Antrieb des Bücherkassettenwagens 22 und der Saugzugmotor
11 eingeschaltet. Sobald diese ihre maximale Drehgeschwindigkeit
erreicht haben, werden die Magnetventile y1, y3 und y4 geöffnet. Daraufhin
strömt Luft in die Behandlungskammer. Mittels des Umluftmotors 2
strömt vorgewärmte Luft (maximal 35°C) durch die Bücher 27 und belüftet
die Seiten. Dabei werden lose Partikel entfernt und weggesaugt. Nach Ablauf
eines vorgegebenen Zeitintervalls werden die Ventile y1, y3 und y4
geschlossen.In a first treatment phase, the
In der anschließenden zweiten Phase, der Behandlungsphase, wird die Vakuumpumpe
9 eingeschaltet und Ventil y15 geöffnet und ein Vakuum von
300 mbar eingestellt.In the subsequent second phase, the treatment phase, the
Gleichzeitig läuft der Umluftmotor 2 und die Heizung. So werden die Bücher
warmgehalten. Nach Erreichen eines Unterdrucks von 300 mbar
schließt Ventil y15 und die Vakuumpumpe 9 bleibt stehen. Die Ventile y5
bis y14 öffnen sich kurzfristig der Reihe nach und durch einen so erzeugten
kurzen Luftstoß wird das pulverförmige Laugenanhydrid in den Behältern 1
bis 10 (6) aufgewirbelt.The circulating air motor 2 and the heating run at the same time. That's how the books are
kept warm. After reaching a negative pressure of 300 mbar
valve y15 closes and the
Das aufgewirbelte Pulver wird in die Behandlungskammer 21 eingesaugt
und durch die Düsen 28 in die Bücher 27 injiziert, und zwar in Form einer
turbulenten Strömung. Dieser Vorgang wird so oft wiederholt bis sich der
Luftdruck auf 600 mbar erhöht. Die Umlaufmotoren 2 wirbeln das Pulver
also durch die Bücher 27, welche hin- und herbewegt werden und verteilen
es gleichmäßig auf alle Seiten. Das Papier wird mit dem Pulver gesättigt.The whirled up powder is sucked into the
In einer anschließenden dritten Phase, der Konditionierungsphase wird dafür gesorgt daß zur Ausbildung einer Lauge aufgrund des injizierten Pulvers hinreichend Feuchtigkeit zur Verfügung steht, zumal das vorher angelegte Vakuum dafür gesorgt hat daß die den Büchern die natürliche Restfeuchte entzogen wurde.In a subsequent third phase, the conditioning phase is used for this worried that to form a lye due to the injected powder sufficient moisture is available, especially since the previously created Vacuum ensured that the books had the natural residual moisture was withdrawn.
Zu diesem Zweck wird schon während der Behandlungsphase eine Wasserringpumpe
4 eingeschaltet die Dampf erzeugt. Der erzeugte Dampf kann
durch die Ventile y1 und y2 entweichen. Das Ventil y1 wird dann geschlossen
und das Regelventil y3 langsam geöffnet und Dampf in die Behandlungskammer
21 eingezogen. Da die Luft in der Behandlungskammer
21 ständig warmgehalten wird, kann der Dampf auf den Bücherblättern
nicht kondensieren und dringt in das Papier ein. Der Dampf wird solange
eingesaugt, bis ein Druckausgleich bei ca. 1000 mbar erreicht ist. Dann
werden die Ventile y2 und y3 geschlossen und die Wasserringpumpe 4 abgeschaltet. For this purpose, a water ring pump is used during the treatment phase
4 turned on which generates steam. The steam generated can
escape through valves y1 and y2. The valve y1 is then closed
and the control valve y3 slowly opened and steam into the
In einer anschließenden vierten Phase, der Reinigungsphase, werden die
Bücher 27 von dem überschüssigen Pulver gereinigt. Hierzu wird die Umlaufpumpe
10 in einem Separator 7 eingeschaltet. Düsen besprühen alle
Luftöffnungen mit Wasser. Ein Saugzugmotor 11 wird eingeschaltet. Die
Ventile y1, y3 und y4 werden geöffnet. Die Luft strömt durch die Behandlungskammer
21 und nimmt lose Pulverpartikel mit. In dem Separator 7
wird die Luft von dem Pulverstaub separiert und sauber in die Atmosphäre
zurückgeleitet. Nach einem vorgegebenen Zeitraum schließen alle Ventile
und die Motoren schalten ab.In a subsequent fourth phase, the cleaning phase, the
Nun kann die Behandlungskammer 21 geöffnet und der Buchkassettenwagen
23 mit den Büchern 27 entnommen werden. Es wird nun eine optische
Kontrolle durchgeführt und erforderlichenfalls werden einzelne Bücher 27
nachgereinigt. Außerdem wird eine pH-Messung durchgeführt, um auf diese
Weise eine Erfolgskontrolle zu bewerkstelligen.Now the
