Abstract

The rotary tabletting machine possesses a die plate (6) which is connected to a drive shaft and in which upper and lower rams (7, 8), whose position is controlled by cams (9, 10), are guided. These cams (9, 10) are provided with holders (14; 15). In machines of this type, it is only possible to exchange the die plate, for example for the purpose of cleaning individual parts when the tablet material to be pressed is changed, after a prior dismantling of the individual rams and their cam guides. This results in long shutdown times. This situation is remedied if the holders (14, 15) are connected to fixed housing parts (4) by detachable connecting means (40) and to the die plate (6) by drivers (12), to be precise in such a way that after the connecting means (40) have been detached, the die plate (6), together with the rams (7, 8) and the cams (9, 10), can be lifted from the drive shaft (1). These connecting means may consist of screws or of clamping connections. The drivers provided may be pins (12) which engage in annular grooves (19) of the die plate. <IMAGE>

Description

Die Erfindung betrifft eine Rundlauf-Tablettierma­schine mit einer in einem Gehäuse drehbar gelagerten und mit einer Antriebswelle verbundenen Matrizen­scheibe, in der Oberund Unterstempel geführt sind, deren Stellung beim Umlauf der Matrizenscheibe durch ortsfeste Kurven gesteuert wird, die mit Haltern versehen sind.The invention relates to a rotary tableting machine with a die plate rotatably mounted in a housing and connected to a drive shaft, in which upper and lower punches are guided, the position of which is controlled during the circulation of the die plate by stationary curves which are provided with holders.

Für eine wirtschaftliche Nutzung von Tablettenpres­sen ist es notwendig, daß die Zeiten sowohl für die Umrüstung einer Maschine zur nachfolgenden Herstel­lung einer anderen Tablettensorte wie auch für die Reinigung von einzelnen Maschinenteilen anläßlich einer Umstellung auf ein anderes Tablettenmaterial möglichst kurz sind im Verhältnis zu der Zeit des Betriebes der Tablettenpresse bzw. der Produktions­zeit. Allgemein erschien es deshalb bisher zweckmä­ßig, Tabletten einer bestimmten Sorte über einen längeren Zeitraum wie beispielsweise über fünf Tage hinweg zu produzieren und danach die Maschine über mehrere Stunden hinweg unter Ausfall der Produktion zu reinigen für eine nachfolgende Verarbeitung eines anderen Tablettenmaterials oder auch eine zusätzli­che Umrüstung für die nachfolgende Herstellung grö­ßerer oder kleinerer Tabletten unter anderen Press drücken.For an economical use of tablet presses it is necessary that the times for the conversion of a machine for the subsequent manufacture of another type of tablet as well as for the cleaning of individual machine parts are necessary a changeover to a different tablet material is as short as possible in relation to the time of operation of the tablet press or the production time. In general, therefore, it has so far seemed expedient to produce tablets of a certain type over a longer period of time, for example five days, and then to clean the machine for several hours without production for subsequent processing of another tablet material or an additional changeover for press the subsequent manufacture of larger or smaller tablets under different press.

Ein steigendes Leistungsvermögen von Tablettenpres­sen, das Bedürfnis nach möglichst kleiner Lagerhal­terung von Pressmaterial sowie steigende Anforderun­gen an den Reinheitsgrad von Tabletten durch die Arzneimittelgesetzgebung führen jedoch allmählich zu ständig kleiner werdenden Chargengrößen, d.h. Zeiten, innerhalb derer Tabletten einer Sorte herge­stellt werden.However, the increasing performance of tablet presses, the need for the smallest possible storage of pressed material and increasing requirements for the degree of purity of tablets due to pharmaceutical legislation are gradually leading to smaller and smaller batch sizes, i.e. Times during which tablets of a variety are made.

Um den Zeitaufwand gering zu halten, der notwendig ist für ein Umrüsten der Maschine beispielsweise durch eine andere Stempelteilung oder nur andere Stempeldrücke und der notwendig ist für eine Reini­gung von Einzelteilen anläßlich eines Wechsels des zu verpressenden Tablettenmaterials sind viele Über­legungen angestellt worden wie ein Teilaustausch der Maschine vereinfacht werden kann. Daraus ergab sich eine bekannte Lösung, nach welcher der Rotor bzw. die Matrizenscheibe verhältnismäßig einfach aus­tauschbar ist. Ein Austausch der Matrizenscheibe ist bei dieser Lösung jedoch erst nach einer vorausge­henden Demontage der einzelnen Stempel und ihrer Kurvenführungen möglich. Ein nennenswerter Zeitge­winn, welcher den effektiven Produktionszeiten zu­gute käme, läßt sich demzufolge nicht erreichen.In order to keep the time required, which is necessary for converting the machine, for example Through a different stamp division or only different stamp pressures and which is necessary for cleaning individual parts when changing the tablet material to be compressed, many considerations have been made as to how a partial exchange of the machine can be simplified. This resulted in a known solution, according to which the rotor or the die plate can be replaced relatively easily. With this solution, however, the die plate can only be replaced after the individual punches and their curve guides have been dismantled. As a result, it is not possible to achieve any significant time savings that would benefit the effective production times.

Aufgabe der Erfindung ist es, durch eine neuartige Gestaltung der Tablettiermaschine das Verhältnis zwischen den Produktionszeiten und den Stillstands­zeiten wegen einer Umrüstung und Reinigung der Ma­schinenteile wesentlich zu verbessern. Gemäß der Er­findung ist dafür vorgesehen, daß die Halter der Kurven durch lösbare Verbindungsmittel mit ortsfe­sten Maschinenteilen oder Gehäuseteilen und durch Mitnehmer mit der Matrizenscheibe derart verbunden sind, daß nach einem Lösen der Verbindungsmittel die Matrizenscheibe zusammen mit den Ober- und Unter­stempeln und den Kurven von der Antriebswelle abzu­heben ist. Dadurch ist der Rotor komplett mit den Stempeln und Kurven außerhalb der Presse auszurüsten und zu reinigen bzw. umzurüsten, während die Presse benutzt werden kann durch Ausnutzung eines gleichar­tigen oder gleichen Bausatzes, der vor der Entnahme des ersten Bausatzes bereits gereinigt und auf die neue Produktion eingerüstet wurde. Das hat mit ande­ren Worten zum Vorteil, daß der größte Anteil der notwendigen Reinigungs- und Aufrüstungsarbeiten ne­ben der Produktion, d.h. während dieser durchzufüh­ren ist, so daß die Rüstzeit und Zeit der Reinigung mit in die Fertigungszeit verlegt wird.The object of the invention is to significantly improve the relationship between the production times and the downtimes due to a retrofitting and cleaning of the machine parts by a novel design of the tableting machine. According to the invention it is provided that the holders of the curves are connected by releasable connecting means to fixed machine parts or housing parts and by drivers to the die plate in such a way that after loosening the connecting means Die plate must be lifted off the drive shaft together with the upper and lower punches and the curves. This means that the rotor must be completely equipped with the punches and curves outside the press and cleaned or converted, while the press can be used by using a similar or the same kit, which was already cleaned before the first kit was removed and equipped for the new production has been. In other words, this has the advantage that the largest part of the necessary cleaning and upgrading work is to be carried out in addition to production, ie during this, so that the set-up time and cleaning time are shifted to the manufacturing time.

Durch die erfindungsgemäße Gestaltung und das erfin­dungsgemäße Verfahren werden die Stillstandszeiten der Pressen beim Umrüsten erheblich reduziert und die Flexibilität des Einsatzes der Pressen durch die Verwendung von Matrizenscheiben mit unterschiedli­cher Teilung zusätzlich erhöht.Due to the design according to the invention and the method according to the invention, the downtimes of the presses during the changeover are considerably reduced and the flexibility of the use of the presses is additionally increased by using die plates with different pitches.

Als Verbindungsmittel für die rotierende Matrizen­scheibe, die feststehenden Kurven, die Antriebswelle und die restlichen Teile der Maschine, d.h. insbe­ sondere das Gehäuse, können einfache Schrauben vor­gesehen werden, von denen nur wenige gelöst und wie­der angezogen zu werden brauchen, um einen Austausch des gesamten Bausatzes zu bewirken. Anstelle von Schrauben können jedoch auch Klemmverbindungen oder Rastmittel bekannter Art Anwendung finden, so daß die Möglichkeit gegeben ist, den Austausch bzw. das Lösen und das Entnehmen eines Bausatzes, der im we­sentlichen aus der Matrizenscheibe, den Stempeln und den Kurven besteht, vollautomatisch durchzuführen, wenn ein Anlaß gegeben ist. Ein derartiges automati­sches Befestigen und Lösen der Baueinheit kann bei­spielsweise durch lineare Antriebe und Spannpratzen erfolgen. Dazu kann für die Entnahme und den Tran­sport der Baueinheit ein Tragarm am Gehäuse der Tab­lettiermaschine angeordnet sein, welcher nach dem Lösen der Verbindungsmittel die Baueinheit erfaßt, aus der Maschine heraushebt und versetzt, um eine andere Baueinheit einzusetzen.As connecting means for the rotating die plate, the fixed curves, the drive shaft and the remaining parts of the machine, ie esp special the housing, simple screws can be provided, of which only a few need to be loosened and tightened again in order to replace the entire kit. Instead of screws, however, clamping connections or locking means of a known type can also be used, so that there is the possibility of carrying out the exchange or loosening and removal of a kit which consists essentially of the die plate, the stamps and the curves, fully automatically. if there is a reason. Such automatic attachment and detachment of the assembly can be done for example by linear drives and clamps. For this purpose, a support arm can be arranged on the housing of the tableting machine for the removal and transport of the structural unit, which, after loosening the connecting means, detects the structural unit, lifts it out of the machine and displaces it in order to use another structural unit.

Weitere Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispie­les, in der auf eine Zeichnung Bezug genommen ist. In der Zeichnung zeigen:

  • Figur 1: eine Tablettiermaschine im Vertikal­schnitt;
  • Figur 2: eine Draufsicht auf die Tablettier­maschine mit Tragarm;
Further features of the invention result from the following description of an exemplary embodiment, in which reference is made to a drawing. The drawing shows:
  • Figure 1: a tableting machine in vertical section;
  • Figure 2 is a plan view of the tabletting machine with a support arm;

Die in der Zeichnung dargestellte Rundläufer-Tablet­tiermaschine besitzt eine drehbeweglich gelagerte Matrizenscheibe 6, die mit einer Vielzahl von Matri­zen 11 versehen ist, welche gleichmäßig über den Um­fang verteilt angeordnet sind. In diesen Matrizen erfolgt das Zusammenpressen von Tablettenmaterial zur Herstellung der Tabletten durch Unterstempel 7 und Oberstempel 8, welche verstellbar in zugehörigen Bohrungen der Matrizenscheibe gehalten sind. Die Zu­stellung der Unterstempel 7 erfolgt durch eine schienenartig ausgebildete Steuerkurve 9 mit Steuerschlitzen 50 und die Zustellung der Oberstem­pel 8 durch eine Steuerkurve 10 mit einem Schlitz 50.The rotary tablet machine shown in the drawing has a rotatably mounted die plate 6, which is provided with a multiplicity of dies 11, which are arranged evenly distributed over the circumference. In these matrices, tablet material is pressed together to produce the tablets by lower ram 7 and upper ram 8, which are adjustably held in associated bores in the die plate. The lower punches 7 are advanced by a rail-like control cam 9 with control slots 50 and the upper punches 8 are delivered by a control cam 10 with a slot 50.

Die Matrizenscheibe 6 ist in einem feststehenden Ge­häuse 4 gelagert. Für ihren Antrieb ist eine An­triebswelle 1 vorgesehen, die durch Lager 2 und 3 im Gehäuse 4 drehbeweglich gehalten ist. Diese An­ triebswelle 1 ist durch Mitnehmer 5 mit der Matri­zenscheibe 6 verbunden, die in der Art einer Passfe­der ausgebildet sind. Für das Verspannen der Matri­zenscheibe 6 mit der Antriebswelle 1 ist eine Spann­schraube 30 vorgesehen, die sich von oben her durch die Matrizenscheibe 6 hindurch unten in die Welle 1 erstreckt, mit der sie durch ein Gewinde 31 ver­bunden ist. Der Kopf der Schraube 30 stützt sich auf einer Spannhülse 87 ab, die mit der Matrizenscheibe 6 verschraubt ist.The die plate 6 is mounted in a fixed housing 4. For their drive a drive shaft 1 is provided which is rotatably held in the housing 4 by bearings 2 and 3. This to Drive shaft 1 is connected by driver 5 to the die plate 6, which are designed in the manner of a feather key. For clamping the die plate 6 with the drive shaft 1, a clamping screw 30 is provided, which extends from above through the die plate 6 down into the shaft 1, to which it is connected by a thread 31. The head of the screw 30 is supported on a clamping sleeve 87 which is screwed to the die plate 6.

Wenn beim Betrieb der Maschine die Matrizenscheibe 6 umläuft und mit ihr auch die Unter- und Oberstem­pel 7 und 8 um die Achse der Antriebswelle 1 herum, so gelangen die Stempeln an die in Figur 1 auf der rechten Seite wiedergegebene Pressstation 96, an der sie durch eine untere Druckrolle 20 und eine obere Druckrolle 21 in die Stellung versetzt sind, in der eine einzelne Tablette innerhalb der Presskammer 80 fertiggepreßt wird.If, during operation of the machine, the die plate 6 rotates and with it the lower and upper punches 7 and 8 around the axis of the drive shaft 1, the punches arrive at the pressing station 96 shown on the right in FIG. 1, at which they pass through a lower pressure roller 20 and an upper pressure roller 21 are set in the position in which a single tablet is pressed within the pressing chamber 80.

Während des Umlaufes der Matrizenscheibe und der Stempel verbleiben die Kurven 9 und 10 feststehend in ihrer Stellung.During the circulation of the die plate and the stamp, the curves 9 and 10 remain stationary in their position.

Die Kurve 9 ist dafür durch eine Schraube 84 mit ei­nem Kurvenhalter 14 verbunden, der mittels Schrauben 40 ortsfest, jedoch lösbar, mit dem Maschinengehäuse 4 verbunden ist. In gleicher Weise ist die Kurve 10 für die Steuerung der Oberstempel 8 mit einem Kur­venhalter 15 durch Schrauben 84 verbunden. Diese Kurvenhalter 15 ist ebenfalls mit dem feststehenden Maschinengehäuse 4 durch Schrauben 40 verbunden, die in Figur 1 nicht sichtbar sind, weil sie in der Ebene liegen, die als Schnittebene senkrecht zu der Zeichenebene steht. Dafür ist der Zylinder 42 durch Schrauben 40 lösbar mit den feststehenden Gehäuse verbunden.For this purpose, the curve 9 is connected by a screw 84 to a curve holder 14, which is connected to the machine housing 4 in a fixed but detachable manner by means of screws 40. In the same way, the curve 10 for the control of the upper punch 8 is connected to a curve holder 15 by screws 84. This curve holder 15 is also connected to the fixed machine housing 4 by screws 40, which are not visible in FIG. 1, because they lie in the plane which is perpendicular to the plane of the drawing as a section plane. For this purpose, the cylinder 42 is detachably connected to the fixed housing by screws 40.

Die Halterungen 14 und 15 für die mit ihnen verbun­denen Steuerkurven 9 und 10 weisen Bohrungen 18 auf, in denen sich Stifte 12 befinden, die sich in Ring­nuten 19 der Matrizenscheibe 6 erstrecken. Diese An­ordnung erlaubt es, die Matrizenscheibe 6 zusammen mit dem Unterstempel 7 sowie dem Oberstempel 8 und den Steuerkurven 9 und 10 als eine gemeinsame Bau­einheit von der Antriebswelle 1 abzuheben und sie gegen eine gleichartige Baueinheit auszutauschen. Dafür sind lediglich die Spannschraube 30 und die Halteschrauben 40 für die untere Steuerkurve 9 sowie in der Zeichnung nicht wiedergegebenen Halteschrau­ben 40 für die obere Steuerkurve 10 zu lösen. Wird anschließend die gesamte Baueinheit beispielsweise mit einem Tragarm 90, der mit einem gabelförmigen Ansatz 88 unter den Kragen 89 der Spannschrauben 87 faßt, angehoben, so erfolgt neben der Mitnahme der Matrizenscheibe 6 durch die als Mitnehmer wirksamen Stifte 12 auch eine Mitnahme der Kurven 9 und 10 und damit der Stempel 7 und 8.The brackets 14 and 15 for the control cams 9 and 10 connected to them have bores 18 in which there are pins 12 which extend in annular grooves 19 of the die plate 6. This arrangement makes it possible to lift the die plate 6 together with the lower punch 7 and the upper punch 8 and the control cams 9 and 10 as a common structural unit from the drive shaft 1 and to exchange them for a similar structural unit. There are only the clamping screw 30 and the retaining screws 40 for the lower cam 9 and In the drawing, not shown retaining screws 40 for the upper control cam 10 to be loosened. If the entire assembly is then raised, for example with a support arm 90, which is gripped with a fork-shaped extension 88 under the collar 89 of the clamping screws 87, in addition to the entrainment of the die plate 6 by the pins 12 acting as entrainers, the curves 9 and 9 are also entrained 10 and thus the stamps 7 and 8.

Um eine solche Anhebung auch zu ermöglichen, wenn sich ein Oberstempel 8 entsprechend der Figur 1 un­ter der Oberen Druckrolle 21 befindet, wird die Welle 22 dieser Druckrolle vorzugsweise höhenver­stellbar angeordnet, so daß zunächst einmal die Druckrolle 21 geringfügig angehoben wird, soweit, bis die Baueinheit geringfügig angehoben und danach seitlich ausgeschwenkt werden kann. Bei diesem Anhe­ben ist jedoch zu vermeiden, daß die sich im Bereich der Druckstation 96 befindlichen und dort nicht durch die Kurven 9 und 10 gehaltenen Stempel aus der Matrizenscheibe herausfallen. Deshalb sind in diesem Bereich Träger 60 und 61 für die Halterung der Köpfe des Unterstempels 7 und Oberstempels 8 vorgesehen.In order to make such an increase possible when an upper punch 8 according to FIG. 1 is located under the upper pressure roller 21, the shaft 22 of this pressure roller is preferably arranged such that it can be adjusted in height, so that the pressure roller 21 is first raised slightly until the assembly can be raised slightly and then swung out sideways. With this lifting, however, it should be avoided that the stamps located in the area of the printing station 96 and not held there by the curves 9 and 10 fall out of the die plate. Therefore, supports 60 and 61 are provided in this area for holding the heads of the lower punch 7 and upper punch 8.

Der Figur 2 ist zu entnehmen, daß der für den Tran­sport der vollständigen Baueinheit vorgesehene schwenkbare Tragarm teleskopartig ausgebildet ist, um die Baueinheit gradlinig beim Schwenken um die Achse 98 versetzen zu können. Anstelle eines solchen Tragarmes sind jedoch auch selbstverständlich andere Konstruktionen möglich, wie beispielsweise Schienen oder überhaupt Einrichtungen, die automatisch zu be­dienen sind.It can be seen from FIG. 2 that the pivotable support arm provided for the transport of the complete structural unit is designed telescopically in order to be able to offset the structural unit in a straight line when pivoting about the axis 98. Instead of such a support arm, of course, other constructions are also possible, such as rails or devices that can be operated automatically.
