Also proposed is the user of the device in the manufacture of tablets.

Description

Vorrichtung zur Herstellung von Pastillen Device for the production of pastilles
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Pastillen, mit einer drehbaren, auf dem gesamten Umfang mit Öffnungen versehenen, waagrecht angeordneten Trommel, an de¬ ren Umfang seitlich ein Ξinweiskörper anliegt, sowie mit ei¬ nem in dieser Trommel gelagerten feststehenden Innenkörper, der mit einem Teil seines Umfanges einen sichelförmigen Spalt mit der Innenwand der Trommel bildet, dessen in Drehrichtung der Trommel hintenliegendes Ende im Bereich des untersten Teiles des Umfanges der Trommel liegt, mit einer Zuführein¬ richtung für eine viskose, fließfähige Schmelze, die durch die Öffnungen der Trommel austropft und mit einer unterhalb der Trommel vorbeigeführten Transport- und/oder Kühlfläche für die von der Trommel abgegebenen Tropfen.The invention relates to a device for the production of pastilles, with a rotatable drum arranged horizontally on the entire circumference, horizontally arranged on the circumference of which an indicator body rests laterally, and with a fixed inner body mounted in this drum, which with part of its circumference forms a crescent-shaped gap with the inner wall of the drum, the end of which lies behind in the direction of rotation of the drum in the region of the lowest part of the circumference of the drum, with a feed device for a viscous, flowable melt which passes through the openings of the drum drips out and with a conveying and / or cooling surface for the drops emitted by the drum.
Vorrichtungen dieser Art sind bekannt (EP 0 339 325 AI) . Bei diesen Vorrichtungen ist zur Zuführung der fließfähigen Schmelze im feststehenden Innenkörper ein axial verlaufender Kanal vorgesehen, von dem aus Verbindungsbohrungen zu einem axial verlaufenden Schlitz am Umfang des Innenkörpers geführt sind, der mit einer mit Düsen versehenen Leiste ausgestattet ist, durch welche das Material nach außen gegeben wird und durch das zyklische Vorbeilaufen der Öffnungen der Trommel in diese und von dort auf eine Kühlfläche abgegeben wird. Der dort vorgesehene exzentrische Spalt dient ausschließlich da¬ zu, um am Außenumfang der Trommel anhaftende Restschmelze, die nicht abgetropft ist, vom Umfang nach innen in die Öff¬ nungen der Trommel zurückzusaugen, ehe diese wieder mit dem axial verlaufenden Schlitz und der Düsenleiste zur Deckung kommen.Devices of this type are known (EP 0 339 325 AI). In these devices, an axially extending channel is provided for supplying the flowable melt in the fixed inner body, from which connecting bores are guided to an axially extending slot on the circumference of the inner body, which is equipped with a bar provided with nozzles through which the material is directed to the outside is given and is released by the cyclical passage of the openings of the drum in this and from there to a cooling surface. The The eccentric gap provided there serves only to suck residual melt adhering to the outer circumference of the drum, which has not dripped, back into the openings of the drum from the circumference, before they come back to cover with the axially extending slot and the nozzle bar .
Vorrichtungen dieser Art sind wegen der auswechselbaren Dü¬ senleisten zur Vertropfung eines breiten Fächers von schmelz¬ fähigem Material geeignet. Sie sind allerdings relativ auf¬ wendig.Because of the exchangeable nozzle strips, devices of this type are suitable for dropping a wide range of meltable material. However, they are relatively complex.
Der Erfindung liegt die Erkenntnis zugrunde, daß man einen Vertropfvorgang überraschenderweise auch schon ausschließlich mit Hilfe des an sich bekannten exzentrischen Spaltes durch¬ führen kann, und zwar ohne daß ein zusätzlicher Aufwand für die Anordnung von Düsenleisten oder anderer Mittel nötig ist, wenn man den Spalt entsprechend groß auslegt.The invention is based on the knowledge that a dripping process can surprisingly also be carried out exclusively with the aid of the eccentric gap known per se, and without additional effort for the arrangement of nozzle strips or other means being necessary when the gap designed accordingly large.
Die Erfindung löst daher die Aufgabe, eine einfachere Vor¬ richtung zur Herstellung von Pastillen der oben angegebenen Art zu schaffen dadurch, daß der sichelförmige Spalt groß ge¬ nug ausgebildet ist, um mindestens die zu vertropfende Menge der Schmelze aufzunehmen und die Zuführeinrichtung für die Schmelze aus einem im Bereich zwischen dem in Drehrichtung der Trommel vorderen Ende des Einweisers und einer am oberen Umfang der Trommel aufsitzenden Wand gebildeten Schacht be¬ steht. Durch eine solche Vorrichtung kann das schmelzfähige Material zunächst von außen durch die Öffnungen der Trommel in deren Inneres eintreten und wird dann im Bereich nach dem unteren Ende des Einweisers durch die Wirkung des immer enger werdenden Spaltes in Tropfen nach außen gedrückt.The invention therefore achieves the object of creating a simpler device for the production of pastilles of the type specified above in that the crescent-shaped gap is designed to be large enough to accommodate at least the amount of melt to be dripped and the feed device for the melt consists of a shaft formed in the area between the front end of the guide in the direction of rotation of the drum and a wall seated on the upper circumference of the drum. By means of such a device, the meltable material can first enter from the outside through the openings of the drum and is then pressed outward in drops in the area after the lower end of the guide by the effect of the increasingly narrow gap.
Zur Lösung der oben erwähnten Aufgabe ist es aber auch - ba¬ sierend auf der erfindungsgemäßen Erkenntnis - möglich, vor¬ zusehen, den sichelförmigen Spalt wie bei der ersten Ausfüh¬ rungsform groß genug zur Aufnahme der zu vertropfenden Menge auszubilden und die Zuführeinrichtung aus. dem hohl ausgebil¬ deten Innenkörper und einer in den in Drehrichtung der Trom¬ mel enger werdenden Spaltbereich hereinführenden Öffnung des hohl ausgebildeten Innenkörpers aufzubauen. Auch eine solche Vorrichtung kann in unerwarteter Weise Schmelzen vertropfen, die anschließend zu Pastillen gekühlt oder geliert werden.To achieve the above-mentioned object, however, it is also possible, based on the knowledge according to the invention, to provide for the crescent-shaped gap to be large enough, as in the first embodiment, to accommodate the amount to be dripped train and the feeder. the hollow inner body and an opening of the hollow inner body leading into the gap area narrowing in the direction of rotation of the drum. Such a device can also drop melts unexpectedly, which are then cooled or gelled into pastilles.
In Weiterbildung des Erfindungsgedankens kann für beide Aus- führungsformen der Einweiskörper jeweils um die Achse der Trommel herum verstellbar gelagert sein, so daß sein Anlage¬ bereich an der Trommel in deren Umfangsrichtung verstellbar ist. Die Größe der für den Vertropfvorgang zur Verfügung ste¬ henden Fläche zwischen Ende des exzentrischen Spaltes und dem Ende des Einweisers kann dadurch verändert werden. Es wird damit auch eine Anpassung an die Viskosität des zu vertrop¬ fenden Materials in gewissem Umfang erreicht.In a further development of the concept of the invention, the guide body for both embodiments can be mounted so as to be adjustable about the axis of the drum, so that its contact area on the drum can be adjusted in its circumferential direction. The size of the area available for the dropping process between the end of the eccentric gap and the end of the guide can be changed as a result. An adjustment to the viscosity of the material to be dripped is also achieved to a certain extent.
Die Erfindung ist anhand von zwei Ausführungsbeispielen in der Zeichnung dargestellt und wird im folgenden erläutert. Es zeigen:The invention is illustrated in the drawing using two exemplary embodiments and is explained below. Show it:
Fig. 1 die schematische Darstellung einer ersten Ausfüh¬ rungsform der Erfindung, bei der das zu vertropfen¬ de Material der Trommel von außen zugeführt wird und1 shows the schematic representation of a first embodiment of the invention, in which the material to be drip-fed is supplied to the drum from the outside, and
Fig. 2 eine zweite Ausführungsform der Erfindung, bei der das zu vertropfende Material dem Trommelinneren zu¬ geführt wird.2 shows a second embodiment of the invention, in which the material to be dripped is fed to the inside of the drum.
In der Fig. 1 ist eine Trommel (1) gezeigt, die an ihrem ge¬ samten Umfang mit Öffnungen (2) versehen ist, mit ihrer Achse (3) horizontal ausgerichtet ist und sich durch einen nicht näher dargestellten Antrieb im Sinne des Pfeiles (4) um ihre Achse (3) dreht. Innerhalb der Trommel (1) ist ein festste¬ hender Innenkörper (5) vorgesehen, der mit dem größten Teil seines Umfanges an der Innenwand der rotierenden Trommel (1) anliegt, im Bereich der linken Hälfte der Trommel (1) jedoch mit der Innenwand der Trommel (1) einen exzentrischen sichel¬ förmigen Spalt (6) bildet. Dieser Spalt (6) besitzt ein obe¬ res Ende (6a) , das etwa im Bereich einer Vertikalebene durch die Achse (3) liegt und ein unteres Ende (6b) , das ebenfalls im Bereich dieser Vertikalebene liegt. Der Spalt (6) ist au¬ ßerdem so ausgelegt, daß er ein Volumen aufweist, das groß genug ist, um zumindest eine solche Menge an Schmelze aufneh¬ men zu können, wie sie für den TropfVorgang und die dieser zugrundeliegenden Austrittsmenge erforderlich ist.1 shows a drum (1) which is provided with openings (2) on its entire circumference, is aligned horizontally with its axis (3) and is driven by a drive (not shown) in the direction of the arrow ( 4) rotates around its axis (3). Provided within the drum (1) is a fixed inner body (5) which, with most of its circumference, on the inner wall of the rotating drum (1) abuts, but forms an eccentric sickle-shaped gap (6) in the area of the left half of the drum (1) with the inner wall of the drum (1). This gap (6) has an upper end (6a) which lies approximately in the area of a vertical plane through the axis (3) and a lower end (6b) which also lies in the area of this vertical plane. The gap (6) is also designed in such a way that it has a volume that is large enough to be able to absorb at least the amount of melt required for the dripping process and the outlet quantity on which it is based.
Am Außenumfang der Trommel (1) liegt ein Einweiskörper (7) mit einem Teil seiner Innenfläche an, der schwenkbar an der Achse (3) angeordnet ist und nach oben hin einen Einlaufspalt mit der Außenfläche der Trommel (1) bildet. Am Außenumfang der Trommel (1) ist außerdem ebenfalls etwa im Bereich der vorher erwähnten Vertikalebene eine Wand (8) aufgesetzt, die mit der Innenwand (7a) des Einweiskörpers (7) einen Zuführ¬ schacht für eine Schmelze bildet, die viskos und fließfähig ist und die im Sinne des Pfeiles (9) zugeführt wird. Natür¬ lich wäre es auch möglich, die Wand (8) in die Lage (8') zu bringen. Auch dann würde ein Einlaufschacht gebildet, durch den fließfähiges Material dem Inneren der Trommel (1) zuge¬ führt werden kann.On the outer circumference of the drum (1) lies a guide body (7) with a part of its inner surface, which is pivotally arranged on the axis (3) and forms an inlet gap upwards with the outer surface of the drum (1). On the outer circumference of the drum (1) there is also a wall (8) placed approximately in the area of the previously mentioned vertical plane, which forms with the inner wall (7a) of the guide body (7) a feed shaft for a melt which is viscous and flowable and which is fed in the direction of arrow (9). It would of course also be possible to bring the wall (8) into position (8 '). An inlet shaft would then also be formed, through which flowable material can be fed to the interior of the drum (1).
Das im Sinn des Pfeiles (9) zugeführte fließfähige Material, insbesondere eine Schmelze, dringt nun durch die im Bereich des sichelförmigen Spaltes (6) nach oben offenen Öffnungen (2) in diesen Spalt (6) ein und fließt aufgrund der Schwer¬ kraft, teils aber auch durch die Rotationsbewegung der Trom¬ mel (1) nach unten in den Bereich, in dem der Spalt (6) von seinem größten Querschnitt wieder in einen kleineren Quer¬ schnitt übergeht. Da der Querschnitt des Spaltes sich bis zu seinem größten Querschnitt, d.h. also etwa im Bereich des Schachtes zwischen der Wand (7a) und der Wand (8) vergrößert, wird auch ein an sich bekannter Ansaugeffekt auf das außen an bThe flowable material, in particular a melt, supplied in the direction of the arrow (9) now penetrates into this gap (6) through the openings (2) which are open at the top in the area of the crescent-shaped gap (6) and flows due to the force of gravity, partly also due to the rotational movement of the drum (1) down into the area in which the gap (6) changes from its largest cross section into a smaller cross section. Since the cross section of the gap increases up to its largest cross section, that is to say approximately in the region of the shaft between the wall (7a) and the wall (8), a suction effect known per se is also exerted on the outside b
der Trommel anstehende schmelzfähige Material ausgeübt, das dadurch nach innen gezogen wird.the meltable material in contact with the drum is pulled inwards.
In dem Bereich nach dem Ende (7b) des Einweiskörpers (7) wer¬ den die Öffnungen (2) der Trommel (1) wieder frei. Da in die¬ sem Bereich auch der Querschnitt des Spaltes (6) abnimmt, wird das im Spalt (6) befindliche Material aus den Öffnungen (2) herausgedrückt, bis es in der Form von Tropfen (10) auf ein unterhalb der Trommel (1) geführtes Band (11) fällt, das im Sinn des Pfeiles (12) bewegt wird. Dieses Band (11) kann ein Kühlband sein, auf dem die Tropfen (10) zu Pastillenform erstarren. Je nach dem vertropften Material kann das Band (11) aber auch ein Transportband sein, auf dem die Tropfen zu Pastillen gelieren.In the area after the end (7b) of the guide body (7), the openings (2) of the drum (1) are cleared again. Since the cross section of the gap (6) also decreases in this area, the material located in the gap (6) is pressed out of the openings (2) until it drops in the form of drops (10) onto one below the drum (1 ) guided belt (11) falls, which is moved in the direction of arrow (12). This belt (11) can be a cooling belt on which the drops (10) solidify into a pastille shape. Depending on the dripped material, the belt (11) can also be a conveyor belt on which the drops gel into pastilles.
Die Fig. 2 zeigt ebenfalls eine rotierende Trommel (1) mit Öffnungen (2) mit einem Einweiskörper (7) und einem Kühl- oder Transportband (11) , so daß für diese Teile auch die gleichen Bezugszeichen verwendet worden sind. Unterschiedlich zu der Ausführungsform der Fig. 1 ist hier, daß ein Innenkör¬ per (13) vorgesehen ist, der die Form eines hohlen Rohres hat, durch welches das zu vertropfende Material dem Innenraum der Trommel (1) zugeführt wird. Das Material, beispielsweise eine Schmelze, kann axial in den rohrförmigen InnenkörperFig. 2 also shows a rotating drum (1) with openings (2) with a guide body (7) and a cooling or conveyor belt (11), so that the same reference numerals have been used for these parts. Different from the embodiment of FIG. 1 is that an inner body (13) is provided which has the shape of a hollow tube through which the material to be dripped is fed to the interior of the drum (1). The material, for example a melt, can axially into the tubular inner body
(13) eingeführt werden und verläßt dann im Inneren der Trom¬ mel (1) den Hohlraum des Innenkörpers (13) durch Öffnungen(13) are introduced and then leaves the cavity of the inner body (13) through openings in the interior of the drum (1)
(14) , die vom Innenkörper (13) aus in den entsprechend groß ausgelegten sichelförmigen Spalt (6) zwischen Innenkörper(14) from the inner body (13) into the correspondingly large crescent-shaped gap (6) between the inner body
(13) und der Innenwandung der Trommel (1) münden, und zwar in einem Bereich der links von einer durch die Achse (3) geleg¬ ten Vertikalebene liegt. Dabei ist die Materialzufuhr bei dieser Ausführungsform so zu bestimmen, daß im wesentlichen nur der sich verjüngende Teil des sichelförmigen Spaltes ge¬ füllt wird, so daß auch dann im Bereich unterhalb der Unter¬ kante (7b) des Einweiskörpers (7) der Vertropfungsvorgang in der anhand des Ausführungsbeispieles der Fig. 1 geschilderten Weise vor sich gehen kann. Gestrichelt ist noch eine Variante eingezeichnet, bei der der Innenkörper (13') nicht als ein zylindrisches Rohr, wie das mit (13) gekennzeichnete Teil ausgebildet ist, sondern als ein mit einem zylindrischen Hohlraum (15) versehener Körper (13'), der sich in dem rechts von einer durch die Achse (3) verlaufenden Vertikalebene befindlichen Bereich an der Innen¬ wand der rotierenden Trommel (1) anlegt. Bei dieser Ausfüh¬ rungsform braucht die Materialzufuhr in den Spalt (6) nicht in der gleichen Weise, wie bei der anderen Ausführungsform so gesteuert werden, daß nur der untere sich verengende Teil des Spaltes (6) gefüllt wird. Das zu vertropfende Material kann in diesem Fall in dem zwischen dem Einweiskörper (7) und der Wand (13'a) gebildeten Trichter gehalten werden. (13) and the inner wall of the drum (1) open, in a region to the left of a vertical plane through the axis (3). The material supply in this embodiment is to be determined in such a way that essentially only the tapering part of the crescent-shaped gap is filled, so that the dropletization process in the area below the lower edge (7b) of the guide body (7) 1 can go on based on the embodiment of FIG. A variant is shown in dashed lines, in which the inner body (13 ') is not designed as a cylindrical tube, like the part marked with (13), but as a body (13') provided with a cylindrical cavity (15) bears on the inner wall of the rotating drum (1) in the area to the right of a vertical plane running through the axis (3). In this embodiment, the material feed into the gap (6) does not need to be controlled in the same way as in the other embodiment in such a way that only the lower, narrowing part of the gap (6) is filled. The material to be dripped can in this case be held in the funnel formed between the guide body (7) and the wall (13'a).
