Description
Die Erfindung geht aus von einer Vorrichtung zum Verbinden
zweier Packstoffbahnen nach dem Oberbegriff des Anspruchs 1.
Derartige bekannte Vorrichtungen werden insbesondere zum
Versiegeln einer aus thermoplastischem Material bestehenden,
und mit Näpfen für Tabletten, Dragees o.a. versehenen
Kunststoffbahn mit einer Deckfolie verwendet. Um die zum
Versiegeln notwendige Temperatur bei schwierig zu
verarbeitenden Deckfolien zu erreichen ist es bekannt,
zusätzlich zu einer Heizwalze eine vor der Heizwalze
angeordnete Vorwärmeinrichtung für die Deckfolie anzuordnen.
Diese Vorwärmeinrichtung besteht beispielsweise aus zwei
elektrisch beheizbaren ebenen Platten, die nahe der Ober
bzw. Unterseite der Deckfolie angeordnet sind, und diese
durch Strahlungswärme erwärmen.
In der Praxis hat es sich gezeigt, daß derartige
Vorwärmeinrichtungen unter Umständen nicht zufriedenstellend
arbeiten, d. h., daß eine dichte Siegelung nicht
gewährleistet ist. Unter schwierig zu verarbeitenden
Deckfolien sind beispielsweise besonders gut
wiederverwertbare Deckfolien zu verstehen, oder solche, die
besondere funktionelle Eigenschaften besitzen. Das betrifft
insbesondere sogenannte "Peal-off" Deckfolien, die
einerseits eine dichte Verbindung zur Kunststoffbahn, und
andererseits ein einfaches manuelles Abschälen der Deckfolie
von der Kunststoffbahn ermöglichen sollen.
Die erfindungsgemäße Vorrichtung zum Verbinden zweier
Packstoffbahnen mit den kennzeichnenden Merkmalen des
Anspruchs 1 hat demgegenüber den Vorteil, daß auch schwierig
zu verarbeitende Deckfolienmaterialien sicher und
zuverlässig verarbeitet werden können, so daß stets dichte
Siegelungen mit der Kunststoffunterbahn entstehen. Dies wird
erfindungsgemäß durch eine besondere Ausbildung der
Vorheizeinrichtung erzielt, deren Heizkeil nahe bis an den
Kontaktbereich von Heiz- und Siegelrolle heranreicht.
Weitere Vorteile und vorteilhafte Weiterbildungen der
erfindungsgemäßen Vorrichtung ergeben sich aus den
Unteransprüchen und der Beschreibung. Eine besonders gute
Verbindung der beiden Packstoffbahnen läßt sich erzielen,
wenn dem Heizkeil eine zweite, an sich bekannte,
plattenförmige Vorwärmeinrichtung vorgeschaltet ist.
Zusätzlich oder anstelle dieser plattenförmigen
Vorwärmeinrichtung kann jedoch auch die Siegelwalze
beheizbar ausgebildet sein. Durch eine separate
Temperaturregelung der Siegelwalze und des Heizkeils läßt
sich der Siegelvorgang besonders gut dem Material der
Kunststoffbodenbahn anpassen. Durch eine spezielle Anordnung
des Heizkeils kann ferner ein Anhaften der Deckfolie am
Heizkeil verhindert werden. Deshalb kann der Heizkeil
vorteilhafterweise auch mit Temperaturen nahe oder über dem
Schmelzpunkt der Deckfolie betrieben werden. Durch die damit
verbundene Strahlungswärme des Heizkeils ist es möglich,
besonders viel Wärmeenergie auf die Deckfolie zu übertragen.
Die Siegelqualität kann zusätzlich verbessert werden, wenn
die Strahlungswärme des Heizkeils auch auf die
Kunststoffbodenbahn einwirkt. Durch eine separate Regelung
der Temperaturen des Heizkeils, der Vorwärmeinrichtung und
ggf. der Siegelwalze ist es möglich, die Vorrichtung an das
jeweilige Deckfolienmaterial optimal anzupassen. Bestehende
Vorheizeinrichtungen können durch den Anbau des Heizkeils
relativ einfach modifiziert werden. Durch die starre
Verbindung des Heizkeils mit der Vorheizeinrichtung ist es
möglich, ein mechanisch besonders einfaches Wegschwenken der
gesamten Heizeinrichtung, beispielsweise bei einer
Produktionspause, zu erzielen.
Zwei Ausführungsbeispiele der Erfindung sind in der
Zeichnung dargestellt und werden in der nachfolgenden
Beschreibung näher erläutert. Es zeigen die Fig. 1 eine
Vorrichtung zum Verbinden zweier Packstoffbahnen vereinfacht
im Längsschnitt während zweier Betriebsphasen, und die Fig.
2 ein abgewandeltes Ausführungsbeispiel nach Fig. 1
ebenfalls im Längsschnitt.
Eine Vorrichtung 10 zum Verbinden zweier Packstoffbahnen 11,
12 hat eine um eine Achse 13 schwenkbare Heizwalze 15 und
eine mit der Heizwalze 15 zusammenwirkende, angetriebene
Siegelwalze 16. Im Berührungsbereich 17 der beiden Walzen
15, 16 werden die beiden als Bodenfolie 11 und Deckfolie 12
bezeichnenden Packstoffbahnen unter Einwirkung von Wärme und
Druck auf an sich bekannte Art und Weise miteinander
verbunden bzw. verschweißt.
In die aus thermoplastischem Material bestehende Bodenfolie 11
wurden an einer vorhergehenden, nicht dargestellten ersten
Station Näpfe 18 eingeformt, die anschließend an einer zweiten
Station beispielsweise mit Tabletten befüllt wurden. Zum
Transport der Bodenfolie 11 weist die Siegelwalze 16 an ihrem
Umfang den Näpfen 18 angepaßte Ausnehmungen 19 auf. Die
Deckfolie 12 besteht beispielsweise aus Aluminium oder aus einem
Kunststoffmaterial, beispielsweise Polypropylen.
Zum Erwärmen der Deckfolie 12 auf die erforderliche
Siegeltemperatur dient neben der Heizwalze 15 eine mit der
Heizwalze 15 zusammenwirkende Vorwärmeinrichtung 20. Die
Vorwärmeinrichtung 20 hat zwei in Deckung mit der Unter- bzw.
Oberseite 22 und 23 der Deckfolie 12 in geringem Abstand
angeordnete Heizplatten 24, 25. Die auf die Oberseite 23
einwirkende Heizplatte 25 ist vorteilhafterweise zum
Wegschwenken um die Achse 13 mit der Heizwalze 15 verbunden. Die
weggeschwenkte Position der Heizwalze 15 und der Heizplatte 25
ist in der Fig. 1 strichpunktiert eingezeichnet. Um eine
möglichst gleichmäßige Erwärmung der Oberseite 23 der Deckfolie
12 zu erzielen, ist die der Heizwalze 15 zugewandte Stirnfläche
27 der Heizplatte 25 der Heizwalze 15 formschlüssig angepaßt, so
daß zwischen der Heizplatte 25 und der Heizwalze 15 nahezu kein
Spalt vorhanden ist. Die der Unterseite 22 der Deckfolie 12
zugewandte Heizplatte 24 reicht bis etwa in die Höhe, in der die
Deckfolie 12 an der Heizwalze 15 anliegt. An das der Siegelwalze
16 zugewandte Ende 28 der Heizplatte 24 schließt sich direkt ein
als Vorheizelement ausgebildeter, separat beheizbarer Heizkeil
30 an, der nahezu bis in den Kontaktbereich 17 der beiden Walzen
15, 16 reicht.
Der Heizkeil 30, der in etwa die gleiche Dicke wie die
Heizplatte 24 besitzt, ist mit der Heizplatte 24 verbunden.
Während Produktionspausen sind Heizplatte 24 und Heizkeil 30
gemeinsam von der Heiz- bzw. Siegelwalze 15 bzw. 16 wegfahrbar,
so daß sich ein so großer Abstand zur Boden- bzw. Deckfolie 11
bzw. 12 ergibt, daß diese nicht mehr erwärmt werden. Auch hier
ist die weggeschwenkte Position der Heizplatte 24 und des
Heizkeils 30 in der Fig. 1 strichpunktiert eingezeichnet.
Die der Deck- bzw. Bodenfolie 12 bzw. 11 zugewandten Heizflächen
32, 33 des Heizkeils 30 sind antihaftbeschichtet und
entsprechend der Form der Heiz- und Siegelwalze 15 und 16
jeweils konvex ausgebildet, so daß sich zu der Deck- bzw.
Bodenfolie 12 bzw. 11 ein jeweils konstanter Abstand einstellt,
wobei dieser Abstand größer ist als der Abstand der Heizplatte
24 zur Unterseite 22 der Deckfolie 12.
Um auch eine großflächige Vorwärmung der Bodenfolie 11 erzielen
zu können, ist bei einer abgewandelten Form der gestrichelt
eingezeichnete Heizkeil 30a parallel zur Oberseite 34 der
Bodenfolie 11 verlängert.
Die oben beschriebene Vorrichtung 10 zum Verbinden zweier
Packstoffbahnen 11, 12 funktioniert wie folgt: Die Heizungen der
Heizwalze 15 sowie der Heizplatten 24, 25 und des Heizkeils 30
bzw. 30a sind getrennt voneinander regelbar. Üblicherweise ist
der Heizkeil 30 bzw. 30a dabei auf die höchste Temperatur
eingeregelt, die nahe oder sogar höher als der Schmelzpunkt der
Deckfolie 12 liegen kann. Durch den Abstand des Heizkeils 30
bzw. 30a von der Deckfolie 12 ist dabei gewährleistet, daß die
Deckfolie 12 diese Temperatur jedoch nicht annehmen kann.
Dagegen besitzen die beiden als Vorheizung dienenden Heizplatten
24, 25 die geringste Temperatur. Zum Verbinden der beiden
Packstoffbahnen 11, 12 wird die Siegelwalze 16 vorzugsweise
kontinuierlich angetrieben, wobei der Vorschub der Bodenfolie 11
durch das formschlüssige Anliegen der Näpfe 18 in den
Ausnehmungen 19 der Siegelwalze 16 erfolgt. Die durch die beiden
Heizplatten 24, 25 und den Heizkeil 30 bzw. 30a vorgewärmte
Deckfolie 12 wird dann im Bereich 17 durch die Heizwalze 15
durch Wärme und Druck mit ihrer Unterseite 22 auf die Oberseite
der Bodenfolie 11 aufgesiegelt. Durch den Heizkeil 30 bzw. 30a
ist sichergestellt, daß die Unterseite 22 der Deckfolie 12 in
Förderrichtung betrachtet mit zur Heizwalze 15 hin zunehmender
Intensität erwärmt werden kann, so daß sich eine besonders gute
Siegelung erzielen läßt. Insbesondere durch die Ausbildung des
Heizkeils 30a mit seiner parallel zur Oberseite 34 der
Bodenfolie 11 verlängerten Heizfläche 33a wird auch die
Bodenfolie 11 vorgewärmt, so daß es zu einer optimalen
Verbindung der beiden Packstoffbahnen 11, 12 kommt, wobei die
Wärmespannungen zwischen der Bodenfolie 11 und der Deckfolie 12
gering gehalten werden können.
Bei dem Ausführungsbeispiel nach der Fig. 2 wird auf die
Vorwärmeinrichtung 20 verzichtet. Statt dessen ist nicht nur die
Heizwalze 15, sondern auch die Siegelwalze 16a beheizbar
ausgebildet. Damit kann die Temperatur dem Material der
Bodenfolie 11 und dem Füllgut angepaßt werden, so daß
Beschädigungen der Bodenfolie 11 bzw. des Füllguts vermieden
werden. Mit der beheizten Siegelwalze 16a ist es möglich,
zusätzlich Wärmeenergie auf die Bodenfolie 11 zu übertragen, was
zu einer besseren Siegelung beiträgt. Zusätzlich ist mit der
Heizwalze 15 eine zusätzliche Umlenkwalze 35 gekoppelt. Über die
Lage der Umlenkwalze 35 zur Heizwalze 15 läßt sich der
Umschlingungswinkel α der Deckfolie 12 mit der Heizwalze 15
verändern. Je größer der Umschlingungswinkel α, desto niedriger
kann die Temperatur der Heizwalze 15 eingestellt sein, um eine
bestimmte Wärmemenge an die Deckfolie 12 abzugeben. Andererseits
läßt sich bei einer vorgegebenen Temperatur der Heizwalze 15 bei
entsprechend größerem Umschlingungswinkel α besonders viel
Wärmeenergie in die Deckfolienbahn 12 übertragen. In der Praxis
weist die Heizwalze 15 eine vorgegebene, konstant eingestellte
Temperatur auf. Durch eine entsprechende Wahl des
Umschlingungswinkels α wird dann sichergestellt, daß die
benötigte Wärmeenergie in die Deckfolienbahn 12 übertragen wird.
Ergänzend wird bemerkt, daß es selbstverständlich auch möglich
ist, die Vorrichtung gemäß des ersten Ausführungsbeispiels
ebenfalls mit einer beheizbaren Siegelwalze 16 auszustatten.
Damit lassen sich die Vorteile beider Ausführungsbeispiele
miteinander verbinden. Außerdem ist es möglich, bei
entsprechendem Material der Bodenfolie 11 auf eine
Antihaftbeschichtung der Heizflächen 33, 33a des Heizkeils 30
bzw. 30a zu verzichten. Weiterhin wird darauf hingewiesen, daß
die Anwendung der Vorrichtung 10 nicht nur auf die im
Ausführungsbeispiel beschriebenen Blisterbahnen beschränkt ist,
sondern grundsätzlich auf zwei miteinander zu verbindende
Packstoffbahnen übertragbar ist.
