Definitions
- the invention relates to a gravity mixer for pharmaceutical products with a transport and storage container according to the preamble of the main claim.
- a mixing device for solid particles has become known from EP-A-77 162, in which a rotatably mounted receptacle for the material to be mixed is received Container is provided, wherein a mixing shaft is provided in the container, which is equipped with mixing blades and extends obliquely to the longitudinal axis of the container. Due to the design of the mixing element projecting into the container, the container itself can only be transported to a limited extent and, since the container itself is cylindrical, a particularly good mixing effect is not achieved.
- a free-fall mixer has become known from FR-A-13 93 602, the container being designed as a double cone which can be easily handled by a forklift.
- the forklift can connect the double cone to a mixer.
- a disadvantage of these known devices is the relatively low mixing accuracy, since the material is not whirled and mixed well within the double cone.
- the same considerations apply to the mixer described in EP-A-38 058, in which a plate which otherwise serves as a shut-off plate can be set as a deflection plate, but which only results in a deflection and no thorough mixing of the material to be mixed.
- a double cone mixer in which the mixing accuracy is to be improved in that, for example, baffles are installed in the lid-like container part. These relatively small baffles do not protrude into the other part of the container and do not lead to intensive mixing of the mix.
- the invention has for its object to provide a gravity mixer for pharmaceutical products, which enables fast mixing times with low product stress and which can also be used as a transport container, so that this has hitherto been possible. U. necessary transfer of the often very toxic products is avoided.
- the invention proposes a gravity mixer that can be connected to a conventional pharmaceutical lifting column, the gravity mixer being designed as a transport container. Connection devices for the transport and storage container are carried by the pharmaceutical lifting column, whereby then a rotating or tumbling movement of the transport and storage container can be brought about via the pharmaceutical lifting column and a corresponding load reversing gear.
- This transport and storage container then serves as a mixing container.
- at least one mixer element is used in the transport and storage container, which is arranged on a lid-like closure.
- the usual lid-like closure of the container can be exchanged for the closure equipped with the mixing elements and now the mixing elements in the interior of the container cause an additional movement in the mixing material during the rotating or swiveling movement of the container, with the material to be mixed not only from above each time the container is rotated down, but is additionally conveyed by gravity at 180 ° rotation to one of the two sides. Due to the symmetrical design of such mixing elements, the material is mixed with each rotation of the container in the counter-rotating process and a good mixing intensity and mixing accuracy can be demonstrated, which almost equals the positive mixing advantageous in terms of mixing accuracy. At the same time, the product is stressed very gently.
- the same transport and storage container is used to load tablet presses, for example, and the special cover equipped with the mixing elements can be exchanged for a conventional cover.
- pelleting of goods is also possible with the gravity mixer designed according to the invention. If only a small amount of moisture is added to a dusty material filled into the transport and storage container and the container is then set in the prescribed tumbling motion, the material is pelletized, so that it is possible to subsequently pelletize the material after an intensive mixing process, which is particularly important in the pharmaceutical industry.
- 1 denotes a pharmaceutical lifting column, in which a lifting carriage 2 is arranged, which is driven by a lifting drive 3.
- the pharmaceutical lifting column 1 carries a load reversing gear 4, to which a receiving eccentric 5 connects, which is equipped at its end according to FIGS. 2 to 4 with a fork piece 7, which can be moved into drive pockets 6 arranged on a transport and storage container 8.
- the transport and storage container 8 has a discharge cone 14 and 11 denotes a chassis for transporting this container.
- a filling opening in the transport and storage container 8 is closed by a closure lid 10, which can be equipped with grommets 12 and which carries mixer elements 9 and 9a, the design and design of which are more clearly shown in FIGS. 1, 4 and 7 is recognizable.
- two mixer elements 9 and 9a are provided which extend in the longitudinal axis Y-Y of the transport and storage container and are arranged obliquely with respect to the axis X-X of the storage container.
- the walls of the mixer elements are preferably concave, as can be clearly seen in FIG. 7.
- the central longitudinal axis Z of the mixer elements 9 and 9a is in the first and third quadrants I and III, see above as the plan view in Fig. 4 clearly shows. 1 and 4, the mixer elements 9, 9a are shown with closed walls. However, slots or other through openings can also be provided here.
- Fig. 1 the path of the product to be mixed is designated by the reference symbol W and it can be seen that with each rotary movement of the mixer container 8, regardless of whether it is a complete revolution or a reciprocating pivoting movement, the mix in addition to the free fall caused by gravity, is deflected by the mixer elements 9 and 9a and thereby continuously performs a circulating movement, which leads to a gentle but intensive mixing of the material.
- the closure lid 10 with the mixer elements 9 and 9a arranged thereon can be removed and replaced with a normal closure lid, and the container 8 can then be guided, for example, to the subsequent processing stations via the chassis 11.
- a container 18 is polygonal, preferably square, and a discharge cone 24 also has a corresponding polygonal shape.
- this container 18 is equipped with a support frame 27 which is firmly connected to the container.
- a sealing cover 20 carries the mixer elements 9 and 9a, the sealing cover 20 being able to be coupled to a connecting device 21 or being firmly carried by the connecting device 21 .
- the connecting device 21 is designed as an eccentric angle with a horizontal arm 26 and a vertical arm 25, the vertical arm 25 connecting to the load reversing gear 4 of the pharmaceutical lifting column 1.

Abstract
Description
Die Erfindung bezieht sich auf einen Schwerkraftmischer für Pharmaprodukte mit einem Transport- und Lagerbehälter gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a gravity mixer for pharmaceutical products with a transport and storage container according to the preamble of the main claim.
In der Pharmaindustrie ist es eine ständige Aufgabe, schwierige pharmazeutische und/oder chemische Produkte zu homogenisieren, wobei es häufig darauf ankommt, daß die Produkte beim Mischprozeß keinem die Oberfläche verändernden Abrieb unterliegen. Der Mischprozeß sollte daher möglichst schnell und möglichst intensiv durchgeführt werden.It is a constant task in the pharmaceutical industry to homogenize difficult pharmaceutical and / or chemical products, it often being important that the products are not subject to surface abrasion during the mixing process. The mixing process should therefore be carried out as quickly and intensely as possible.
Da es sich bei den chemischen und pharmazeutischen Produkten sehr häufig um stark toxische Produkte handelt, ist ein Umfüllen dieser Produkte aus einem Transportbehälter in den Mischer und aus dem Mischer wieder in einen Transportbehälter, um von diesem dann zu den weiteren Verarbeitungsstationen übergeben zu werden, nachteilig.Since the chemical and pharmaceutical products are very often highly toxic products, transferring these products from a transport container into the mixer and from the mixer back into a transport container in order to then be transferred from it to the further processing stations is disadvantageous .
Aus der EP-A-77 162 ist eine Mischvorrichtung für feste Partikelchen bekanntgeworden, bei der ein das zu mischende Gut aufnehmender, drehbar gelagerter Behälter vorgesehen ist, wobei in dem Behälter eine Mischwelle vorgesehen wird, die mit Mischflügeln bestückt ist und sich schräg zur Behälterlängsachse erstreckt. Durch die Ausbildung des in den Behälter hineinragenden Mischorganes ist der Behälter selbst nur begrenzt transportabel und, da der Behälter selbst zylindrisch ausgebildet ist, wird kein besonders guter Mischeffekt erreicht.A mixing device for solid particles has become known from EP-A-77 162, in which a rotatably mounted receptacle for the material to be mixed is received Container is provided, wherein a mixing shaft is provided in the container, which is equipped with mixing blades and extends obliquely to the longitudinal axis of the container. Due to the design of the mixing element projecting into the container, the container itself can only be transported to a limited extent and, since the container itself is cylindrical, a particularly good mixing effect is not achieved.
Aus der FR-A-13 93 602 ist ein Freifallmischer bekanntgeworden, wobei der Behälter als Doppelkonus ausgebildet ist, der über einen Gabelstapler leicht gehandhabt werden kann. Der Doppelkonus kann von dem Gabelstapler an einen Mischer angeschlossen werden. Nachteilig bei diesen bekannten Einrichtungen ist die relativ geringe Mischgenauigkeit, da das Gut innerhalb des Doppelkonus nicht gut durcheinandergewirbelt und gemischt wird. Die gleichen Überlegungen treffen zu dem in der EP-A-38 058 beschriebenen Mischer zu, bei welchem zwar eine sonst als Absperrplatte dienende Platte als Umlenkplatte eingestellt werden kann, die aber nur eine Umlenkung und keine gute Durchmischung des Mischgutes bewirkt.A free-fall mixer has become known from FR-A-13 93 602, the container being designed as a double cone which can be easily handled by a forklift. The forklift can connect the double cone to a mixer. A disadvantage of these known devices is the relatively low mixing accuracy, since the material is not whirled and mixed well within the double cone. The same considerations apply to the mixer described in EP-A-38 058, in which a plate which otherwise serves as a shut-off plate can be set as a deflection plate, but which only results in a deflection and no thorough mixing of the material to be mixed.
In der gattungsbildenden FR-A-22 54 362 wird ein Doppelkonusmischer beschrieben, bei dem die Mischgenauigkeit dadurch verbessert werden soll, daß in den deckelartigen Behälterteil zum Beispiel Umlenkbleche eingebaut werden. Diese relativ kleinen Umlenkbleche ragen nicht in den anderen Behälterteil und führen nicht zu einer intensiven Durchmischung des Mischgutes.In the generic FR-A-22 54 362 a double cone mixer is described, in which the mixing accuracy is to be improved in that, for example, baffles are installed in the lid-like container part. These relatively small baffles do not protrude into the other part of the container and do not lead to intensive mixing of the mix.
Der Erfindung liegt die Aufgabe zugrunde, einen Schwerkraftmischer für Pharmaprodukte zu schaffen, der bei geringer Produktbeanspruchung schnelle Mischzeiten ermöglicht und der gleichzeitig als Transportbehälter eingesetzt werden kann, so daß das bisher u. U. erforderliche Umfüllen der häufig sehr toxischen Produkte vermieden wird.The invention has for its object to provide a gravity mixer for pharmaceutical products, which enables fast mixing times with low product stress and which can also be used as a transport container, so that this has hitherto been possible. U. necessary transfer of the often very toxic products is avoided.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.
Mit anderen Worten ausgedrückt schlägt die Erfindung einen Schwerkraftmischer vor, der an eine übliche Pharmahubsäule anschließbar ist, wobei der Schwerkraftmischer als Transportbehälter ausgebildet ist. Von der Pharmahubsäule werden Anschlußvorrichtungen für den Transport- und Lagerbehälter getragen, wobei dann über die Pharmahubsäule und ein entsprechendes Lastwendegetriebe eine rotierende oder taumelnde Bewegung des Transport- und Lagerbehälters herbeigeführt werden kann. Dieser Transport- und Lagerbehälter dient dann als Mischbehälter. Um ein gutes und intensives sowie gleichmäßiges Durchmischen mit hoher Mischgenauigkeit zu erreichen, wird in den Transport- und Lagerbehälter wenigstens ein Mischerelement eingesetzt, das an einem deckelartigen Verschluß angeordnet ist. Der übliche deckelartige Verschluß des Behälters kann gegen den mit den Mischelementen ausgerüsteten Verschluß ausgewechselt werden und nunmehr bewirken die Mischelemente im Inneren des Behälters bei der Rotationsoder Schwenkbewegung des Behälters eine Zusatzbewegung im Mischgut, indem bei jeder Drehung des Behälters das zu mischende Gut nicht nur von oben nach unten, sondern zusätzlich bei 180° Drehung zu einer der beiden Seiten über die Schwerkraft gefördert wird. Durch die symmetrische Ausbildung derartiger Mischorgane wird das Gut bei jeder Drehung des Behälters im Gegenlaufverfahren gemischt und es kann eine gute Mischintensität und Mischgenauigkeit nachgewiesen werden, die fast der hinsichtlich der Mischgenauigkeit vorteilhaften Zwangsmischung gleichkommt. Gleichzeitig wird aber das Produkt sehr schonend beansprucht.In other words, the invention proposes a gravity mixer that can be connected to a conventional pharmaceutical lifting column, the gravity mixer being designed as a transport container. Connection devices for the transport and storage container are carried by the pharmaceutical lifting column, whereby then a rotating or tumbling movement of the transport and storage container can be brought about via the pharmaceutical lifting column and a corresponding load reversing gear. This transport and storage container then serves as a mixing container. In order to achieve good, intensive and uniform mixing with high mixing accuracy, at least one mixer element is used in the transport and storage container, which is arranged on a lid-like closure. The usual lid-like closure of the container can be exchanged for the closure equipped with the mixing elements and now the mixing elements in the interior of the container cause an additional movement in the mixing material during the rotating or swiveling movement of the container, with the material to be mixed not only from above each time the container is rotated down, but is additionally conveyed by gravity at 180 ° rotation to one of the two sides. Due to the symmetrical design of such mixing elements, the material is mixed with each rotation of the container in the counter-rotating process and a good mixing intensity and mixing accuracy can be demonstrated, which almost equals the positive mixing advantageous in terms of mixing accuracy. At the same time, the product is stressed very gently.
Am Ende des Mischvorganges wird derselbe Transportund Lagerbehälter zur Beschickung beispielsweise von Tablettenpressen benutzt, wobei der mit den Mischelementen ausgerüstete Sonderdeckel gegen einen üblichen Deckel ausgewechselt werden kann.At the end of the mixing process, the same transport and storage container is used to load tablet presses, for example, and the special cover equipped with the mixing elements can be exchanged for a conventional cover.
Zusätzlich zu der erreichten vorteilhaften Art des Mischvorganges wird also durch den erfindungsgemäßen Vorschlag der Vorteil erreicht, daß das bisher erforderliche Befüllen und Entleeren eines gesonderten Mischers nicht mehr notwendig ist, so daß damit die Handhabung der häufig sehr toxischen Produkte verbessert wird.In addition to the advantageous nature of the Mixing process is thus achieved by the proposal according to the invention that the previously required filling and emptying of a separate mixer is no longer necessary, so that the handling of the often very toxic products is improved.
Überraschend wurde zudem festgestellt, daß mit dem erfindungsgemäß ausgebildeten Schwerkraftmischer auch ein Pelletieren von Gütern möglich ist. Wird einem in den Transport- und Lagerbehälter eingefüllten staubförmigen Gut nur eine geringe Feuchtigkeitsmenge zugesetzt und wird dann der Behälter in die vorgeschriebene Taumelbewegung versetzt, erfolgt ein Pelletieren des Gutes, so daß es möglich ist, nach einem intensiven Mischvorgang gleichzeitig anschließend das Gut zu pelletieren, was gerade in der Pharmaindustrie von besonderer Bedeutung ist.Surprisingly, it was also found that pelleting of goods is also possible with the gravity mixer designed according to the invention. If only a small amount of moisture is added to a dusty material filled into the transport and storage container and the container is then set in the prescribed tumbling motion, the material is pelletized, so that it is possible to subsequently pelletize the material after an intensive mixing process, which is particularly important in the pharmaceutical industry.

Hier können aber auch Schlitze oder andere Durchtrittsöffnungen vorgesehen sein.The central longitudinal axis Z of the
In Fig. 1 ist der Weg des zu mischenden Produktes mit dem Bezugszeichen W bezeichnet und es ist erkennbar, daß bei jeder Drehbewegung des Mischerbehälters 8, unabhängig ob es sich dabei um eine vollständige Umdrehung oder um eine hin- und hergehende Schwenkbewegung handelt, das Mischgut zusätzlich zu dem durch die Schwerkraft bedingten freien Fall durch die Mischerelemente 9 und 9a umgelenkt wird und dadurch ständig eine Umwälzbewegung durchführt, die zu einem zwar schonenden, aber intensiven Mischen des Gutes führt.In Fig. 1, the path of the product to be mixed is designated by the reference symbol W and it can be seen that with each rotary movement of the mixer container 8, regardless of whether it is a complete revolution or a reciprocating pivoting movement, the mix in addition to the free fall caused by gravity, is deflected by the
Ist der Mischvorgang beeendet, kann der Verschlußdeckel 10 mit den daran angeordneten Mischerelementen 9 und 9a abgenommen werden und gegen einen normalen Verschlußdeckel ersetzt werden und dann kann beispielsweise über das Fahrgestell 11 der Behälter 8 zu den nachfolgenden Verarbeitungsstationen geführt werden.When the mixing process has ended, the
In den Fig. 5 und 6 ist eine abgeänderte Ausführungsform des Transport- und Lagerbehälters dargestellt.5 and 6, a modified embodiment of the transport and storage container is shown.
Während bei der Ausführungsform gemäß den Fig. 1 bis 4 der Behälter 8 rund und der Austragkonus 14 als runder Kegelstumpf ausgebildet ist, ist bei der Ausführungsform gemäß den Fig. 5 und 6 ein Behälter 18 polygonal, vorzugsweise viereckig, ausgebildet und auch ein Austragkonus 24 weist eine entsprechende polygonale Form auf. Zusätzlich ist dieser Behälter 18 mit einem Stützgestell 27 ausgerüstet, das fest mit dem Behälter verbunden ist.While in the embodiment according to FIGS. 1 to 4 the container 8 is round and the
Die bei der Ausführungsform gemäß den Fig. 1 bis 4 noch erforderlichen Gabelstücke 7 sind nicht mehr notwendig, sondern ein Verschlußdeckel 20 trägt die Mischerelemente 9 und 9a, wobei der Verschlußdeckel 20 an eine Anschlußvorrichtung 21 angekoppelt werden kann oder von der Anschlußvorrichtung 21 fest getragen wird. Durch die Verbindung des Verschlußdeckels 20 mit dem Behälter 18 und der Anschlußvorrichtung 21 wird nunmehr der gesamte Behälter 18 ausschließlich über den Verschlußdeckel 20 von der Anschlußvorrichtung 21 getragen.The
