Definitions
- the invention relates to a device for sorting out defective cylindrical medicament capsules of a diameter exceeding a nominal value in at least one direction.
- Drug capsules are used for oral administration of liquid or powdered medicines, which are to take effect with a time delay. They generally consist of a gelatin capsule in which the drug is enclosed.
- the gelatin capsules comprise a centrally arranged, hollow-cylindrical region, which is closed on both sides in the axial direction by hollow domes and filled with the medicament. you will be after their preparation and filling initially collected in bags and transferred for individual administration by means of packaging machines individually in the wells of blister packs, which consist of a thermoformed plastic film.
- the cups are covered on the surface by an aluminum foil for individual removal of the drug capsules 5 and closed, through which each of the drug capsule to be removed can be pressed with proportionate destruction of the aluminum foil and deformation of the respective cup. This can be very hygienic and has proven very successful.
- Separating device having a cylinder with openings formed in the inner wall and forms the basis for the two-part form of the independent claim 1.
- the openings determine the limit size of the objects to be separated.
- the articles are inserted at one end of the cylinder which is mounted at an angle to the horizontal and rotated.
- the objects, which are smaller than the diameter of the openings in the inner wall of the cylinder, are transported by its rotation upwards and are discharged on top of a means of transport, which transports them away.
- the objects which are larger than the diameter of the openings remain on the bottom of the cylinder and move slowly to the lower end, where they are discharged onto another means of transport.
- the invention is based on the object to show a device that allows fully automatic and safe to detect all fully unusable by deformations drug capsules and excrete fully automatically.
- the invention is also intended to be suitable for sorting out other cylindrical bodies which exceed a nominal value which can be arbitrarily determined in at least one direction.
- the device according to claim 1 offers the advantage that it can be used to fully automatically examine large quantities of medicament capsules according to qualitative standards and completely for diameter deviations of individual medicament capsules which exceed arbitrarily definable, permissible deviations. As a result, it is impossible for deformed medicament capsules to enter the packaging machines which have excessively large diameter excesses in at least one direction and block their guides.
- the sieve drum and the devices connected to it are made of metal, preferably of stainless steel, which makes it possible to easily meet the hygienic standards prescribed for pharmaceutical areas in the long term and at the same time to achieve an electrostatic neutralization of the medicament capsules.
- Electrostatic forces namely, can cause a large number of drug capsules to form a chain, which hinders the necessary separation.
- the drug capsules to be controlled can be supplied in a particularly simple manner, defective drug capsules can be easily removed, and possible malfunctions can be easily remedied. Also, the cleaning and replacement of a screen drum against another is particularly easy. Since the screen drum is mounted only on a pair of motor-driven rollers, electrical connections or the like are not affected when replacing a Siebtrommmel. The conversion to drug capsules of a different diameter is thus tool-free and feasible even by unskilled workers.
- the embodiment according to claim 2 offers the advantage that the circulation of the medicament capsules contained in the interior of the sieve drum is not uniformly rolling, but takes place with progressive rotational movement of the sieve drum over different angles of inclination of the respective flat plates at different speeds. This favors a quick and correct, vertical introduction of the drug capsules to be tested in the holes of the drum and thus a particularly rapid workflow.
- the embodiment according to claim 3 offers the advantage that the individual plates can be very easily and manually pulled out in the longitudinal direction of their leadership, cleaned or replaced. For the use of the device in low rooms without crane device that is of great advantage.
- Claim 4 offers the advantage, parallel to the locking of the plates at the same time the interior of the screening drum is limited in the longitudinal direction to the extent required. This speeds up the recovery of operability following the replacement of one or more disks.
- the design of the plates according to claim 5 makes it possible to manufacture the plates in a particularly simple and cost-effective manner, to store and install stacked.
- the design according to claim 6 offers a particularly simple way to eliminate defective drug capsules completely from the device and collect separately.
- the immediate removal of defective drug capsules always provides a maximum number of operational and unclogged holes for further control.
- the embodiment according to claim 7 ensures that defective drug capsules are removed without residue and reliably under all circumstances.
- the embodiment according to claim 8 ensures a complete removal of all possibly stuck in a plate drug capsules without separate control.
- the embodiment according to claim 9 ensures the removal of all possibly stuck in a plate drug capsules in the shortest possible time.
- the embodiment according to claim 10 makes it possible to exchange defective spikes cost.
- the embodiment according to claim 11 offers the advantage that permanently a complete operational and functional safety of the device is ensured without the need for Zuziehung of specialized personnel.
- the embodiment according to claim 12 ensures a particularly reliable implementation of the control process and in particular a uniform and reliable introduction of the drug capsules in the holes. Due to the uniform and very gradual transition of the largest in the smallest diameter of the holes also any damage to the drug capsules are excluded. It also ensures that all critical drug capsules can securely clamp in the holes regardless of the nature of the deformity and can be safely eliminated.
- the inner diameter of the holes is in itself arbitrary and freely definable.
- the embodiment according to claim 13 offers on this basis the advantage that the controlled drug capsules are trouble-free in all current packaging machines processable while avoiding unnecessary difficulties in the control and their guides do not block.
- the embodiment according to claim 14 favors a trouble-free control even more so far, as the inside of the screen drum is formed in almost all areas by sharp-edged polylines, in which the adjacent holes with their funnel-like inlet openings each other limit in the manner of a honeycomb pattern.
- the in the Fig. 1 to 6 serves to sort out cylindrical medicament capsules 1 of a diameter exceeding a nominal value in at least one direction to a critical extent.
- the nominal value is determined empirically and starts with drug capsules 1 from a target value of the diameter of 4 to 8 mm and is so far beyond that the drug capsules concerned pass through the guides of the respective associated packaging machines trouble-free and secure. It may be 4.5 mm in the former case and 9 mm in the latter case.
- other setpoints may be specified.
- FIG. 1 A device shown mounted on a pair of rollers only 2.6 in the region of its outer circumference, rotatable about an axis 2.2, spokes-less sieve drum 2 for receiving the sorted drug capsules 1, which is closed at the end by flanges 2.1 in the region of the outer periphery. At least one roller of the roller pair 2.6 is driven by a motor and the screen drum 2 thereby rotatable.
- the wall of the screen drum 2 has a plurality of radially inwardly widened funnel-shaped holes 3 of an arbitrarily set, smallest diameter, which break through the wall of the screen drum 2 radially.
- the wall of the drum 2 is formed by in the circumferential direction sequential, identically formed, flat plates 5, bounded on both sides by grooves in the circumferential direction and with the grooves on guide pin 2.3 of frontal end flanges 2.1, 2.4 of the screening drum 2 are threaded, which extend parallel to the axis of rotation 2.2 of the screening drum 2.
- a funnel 6 which is open at the top and which is formed at the bottom by a chute, can be removed obliquely from the interior of the falling into the hopper 6 from above into the funnel.
- the second slide 7 is guided into the interior space 4 and are entered via the new drug capsules 1 to be tested.
- the second chute 7 may be replaced by a hose or pipe.
- a receiving device for "good” drug capsules is arranged, since it is intended to supply error-free drug capsules 1, which have passed through the holes 3 of the screen drum 2, the packaging machine, not shown.
- Fig. 2 shows the device after Fig. 1 in cross-section.
- the screen drum 2 is formed by the immediately adjacent in the circumferential direction, flat and circumferentially identical plates 5.
- the screen drum 2 is limited in the longitudinal direction by end flanges 2.1, wherein the end flanges 2.1, 2.4 are connected by parallel to the axis of rotation 2.2 extending evenly distributed in the circumferential direction guide pin 2.3 and wherein the plates 5 are mounted on the guide pin 2.3.
- the plates 5 are mounted parallel to the axial direction removable on the guide pin 2.3 and can be locked by an attachable to the guide pin 2.3 end flange 2.5.
- the plates 5 are bounded on both sides in the circumferential direction by parallel to the axis of rotation extending guide and pushed with the guide grooves on the guide pin 2.3.
- the end flanges 2.1, 2.4 are limited in the region of the outer circumference circular and mounted on a motor-driven roller pair 2.6.
- the pair of rollers 2.6 and the entire device are made of metal, in this case made of stainless steel. This makes cleaning easy. Electrostatic forces can be dissipated easily.
- a storage of the screening drum 2 on rubberized rollers is also possible and helps to lower the noise level of the rotating screen drum 2.
- the rotation of the screen drum 2 is computer controlled temporarily brought to a standstill, if each one of the plates 5 is located above the arranged in the interior of the screen drum, upwardly open hopper 6, wherein mechanical means 7 are present, through which the respective holes in the 3 Drum 2 jammed drug capsules 1 from the holes 3 vertically downwardly ejected and can be thrown into the hopper 6. Thereafter, the screen drum 2 rotates again until a plate 5 is above the funnel 6.
- the ejection of the defective drug capsules 1 from the holes 3 causing means 7 are formed by mandrels, which are vertically inserted from above radially inwardly into the holes 3.
- the funnel 6 engages in each case at the same time all holes 3 of a plate 5 and each of the bores 3 contained in the plate 5 is assigned a separate mandrel, as in Fig. 1 indicated.
- mandrels are attached to a common support 7.1 and at the same time lowered together and parallel to each other in all holes 3 of a plate 5 and removable therefrom.
- the relevant plate 5 is then subsequently fully usable again for carrying out further control operations.
- the mandrels are releasably attached to the support 7.1, for example by a screw connection. They can be easily replaced in case of damage.
- the interruption of the rotation of the screen drum 2 and the operation of the mechanical means 7 are programmatically connected and triggered signal-controlled. This can be computer-controlled regularly recurring.
- the bores 3 have a radially inwardly in the direction of the axis 2.2 in the manner of a Trompetentrichters edge-free, rounded expanded inner diameter. As a result, the medicament capsules impinging on the inner wall easily fall into the bores 3 and optionally parallel to their longitudinal direction.
- the holes 3 have a smallest inner diameter, which is 0.5 to 1.0 mm larger than the nominal diameter of the drug capsules to be tested 1. This ensures safe operation of all known packaging machines.
- Fig. 3 shows a section of a plate 5 in plan view from the inside.
- the holes 3 are bounded by inner surfaces which mutually limit each other on the inside of the screen drum 2 in common cutting edges 5.1.
- the cut edges 5.1 form in their entirety a mutually in transition honeycomb pattern, as in Fig. 3 shown.
- impinging drug capsules are distracted by and guided into the trumpet funnels of the holes 3, in which the actual Control takes place.
- This consists in that the medicament capsules either pass through the bores 3 or become jammed therein and are carried along by the rotation of the sieve drum 2 into a position above the funnel 6, into which they are thrown by the mechanical means 7, which are here formed by pins and led out of the device.
- the mutual distance parallel to each other extending cutting edges 5.1 of each funnel of the holes 3 is greater than the length of the respective drug capsules to be tested 1.
- a slight excess of 10 to 50% is sufficient to significantly accelerate the flow of the drug capsules.
- the cut edges 5.1 have, based on the surface of the plates 5, an uneven wavy course. This helps direct the drug capsules 1 impinging on the surface into the bores and bring them to control
- the adjacent holes are each assigned to each other on the basis of a rectangular grid each gap.
- a square or a triangular basic grid can be chosen.
- a kind of honeycomb pattern of the cut edges in the manner of a honeycomb and an optimal possibility of increasing the permeability of a plate 5 in the area to the greatest possible extent results in the plan view.
Description
Die Erfindung betrifft eine Vorrichtung zum Aussortieren von fehlerhaften zylindrischen Medikamentenkapseln eines einen Nennwert in zumindest einer Richtung übersteigenden Durchmessers.The invention relates to a device for sorting out defective cylindrical medicament capsules of a diameter exceeding a nominal value in at least one direction.
Medikamentenkapseln dienen zur oralen Verabreichung von flüssigen oder pulverförmigen Medikamenten, die zeitverzögert zur Wirkung kommen sollen. Sie bestehen im allgemeinen aus einer Gelatinekapsel, in der das Medikament eingeschlossen ist. Die Gelatinekapseln umfassen einen zentral angeordneten, hohlzylindrischen Bereich, der in axialer Richtung beiderseits durch Hohlkalotten abgeschlossen und mit dem Medikament gefüllt ist. Sie werden nach ihrer Herstellung und Füllung zunächst in Beuteln gesammelt und zur Einzelverabreichung mit Hilfe von Verpackungsautomaten einzeln in die Näpfe von Blisterpackungen überführt, die aus einer tiefgezogenen Kunststofffolie bestehen. Die Näpfe sind zur Einzelentnahme der Medikamentenkapseln 5 oberflächlich durch eine Aluminiumfolie überdeckt und verschlossen, durch die die jeweils zu entnehmende Medikamentenkapsel unter anteiliger Zerstörung der Aluminiumfolie und unter Verformung des jeweiligen Napfes hindurchgepresst werden kann. Dies kann sehr hygienisch erfolgen und hat sich sehr bewährt.Drug capsules are used for oral administration of liquid or powdered medicines, which are to take effect with a time delay. They generally consist of a gelatin capsule in which the drug is enclosed. The gelatin capsules comprise a centrally arranged, hollow-cylindrical region, which is closed on both sides in the axial direction by hollow domes and filled with the medicament. you will be after their preparation and filling initially collected in bags and transferred for individual administration by means of packaging machines individually in the wells of blister packs, which consist of a thermoformed plastic film. The cups are covered on the surface by an aluminum foil for individual removal of the
Ein Problem besteht nun darin, dass die Medikamentenkapseln sich häufig während der Zwischenlagerung sowie beim Transport in den Beuteln deformieren und an zumindest einer Stelle einen unrunden Querschnitt annehmen. Bedingt durch die enthaltene Flüssigkeit oder das Pulver entstehen dabei nicht nur Eindrückungen des Mantels an der einen Stelle nach innen, sondern zugleich and anderer Stelle Auswölbungen oder Vorsprünge nach außen, mit der Folge, dass eine einzelne Medikamentkapsel mit einer solchen Deformation eine Zuführeinrichtung eines Verpackungsautomaten verstopfen, die weitere Zuführung nachfolgender Medikamentenkapseln für lange Zeitblockieren und damit den betreffenden Verpackungsautomaten insgesamt zum Stillstand bringen kann.A problem now is that the drug capsules often deform during storage and during transport in the bags and take on at least one point a non-circular cross-section. Due to the liquid or powder contained not only indentations of the shell arise at one point inwards, but at the same time at other locations bulges or projections to the outside, with the result that a single drug capsule with such a deformation clog a feeder of a packaging machine , the further supply of subsequent drug capsules for long time blocking and thus can bring the relevant packaging machine to a halt overall.
Um dies zu vermeiden ist es bisher üblich, die zu verpackenden Medikamentenkapseln visuell zu kontrollieren und hinreichend stark deformierte Medikamentenkapseln manuell auszuscheiden. Dies ist mit einem erheblichen Arbeitsaufwand sowie der Unsicherheit verbunden, fehlerhafte Medikamentenkapseln zu übersehen oder zu wenig deformierte Medikamentenkapseln ebenfalls mit auszuscheiden.To avoid this, it has hitherto been customary to visually inspect the drug capsules to be packaged and to manually excrete sufficiently severely deformed drug capsules. This is associated with a considerable amount of work and the uncertainty of overlooking faulty drug capsules or of excreting too little deformed drug capsules.
Die
Trennvorrichtung, die einen Zylinder mit in der Innenwand ausgebildeten Öffnungen aufweist und bildet die Grundlage für die zweiteilige Form des unabhängigen Anspruchs 1. Die Öffnungen bestimmen die Grenzgröße der zu trennenden Gegenständen. Die Gegenstände werden an einem Ende des Zylinders, der winklig zur Horizontalen montiert ist und rotiert wird, eingeführt. Die Gegenstände, die kleiner sind als der Durchmesser der Öffnungen in der Innenwand des Zylinders, werden durch seine Rotation nach oben transportiert und werden oben auf ein Transportmittel entladen, das sie weg transportiert. Die Gegenstände, die größer als der Durchmesser der Öffnungen sind, verbleiben auf dem Boden des Zylinders und bewegen sich langsam zu dem unteren Ende, wo sie auf ein weiteres Transportmittel entladen werden.Separating device having a cylinder with openings formed in the inner wall and forms the basis for the two-part form of the
Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zu zeigen, die es erlaubt, alle durch Deformierungen unbrauchbaren Medikamentenkapseln vollautomatisch und sicher zu erkennen und vollautomatisch auszuscheiden. Die Erfindung soll neben dem Assortieren von fehlerhaften Medikamentenkapseln auch zum Aussortieren von sonstigen zylindrischen Körpern geeignet sein, die in zumindest einer Richtung einen willkürlich festlegbaren Nennwert überschreiten.The invention is based on the object to show a device that allows fully automatic and safe to detect all fully unusable by deformations drug capsules and excrete fully automatically. In addition to the assortment of defective medicament capsules, the invention is also intended to be suitable for sorting out other cylindrical bodies which exceed a nominal value which can be arbitrarily determined in at least one direction.
Diese Aufgabe wird erfindungsgemäß bei einer Vorrichtung nach dem Oberbegriff durch die kennzeichnenden Merkmale von Anspruch 1 gelöst. Auf vorteilhafte Weiterbildungen nehmen die Unteransprüche Bezug.This object is achieved in a device according to the preamble by the characterizing features of
Die Vorrichtung nach Anspruch 1 bietet den Vorteil, dass damit vollautomatisch große Mengen von Medikamentenkapseln nach qualitativen Maßstäben sicher und vollzählig auf Durchmesserabweichungen einzelner Medikamentenkapseln untersucht werden können, die willkürlich festlegbare, zulässige Abweichungen überschreiten. Dadurch ist es ausgeschlossen, dass deformierte Medikamentenkapseln in die Verpackungsautomaten gelangen, die in zumindest in einer Richtung unzulässig große Durchmesserüberschreitungen haben und deren Führungen blockieren.The device according to
Die Siebtrommel und die mit ihr verbundenen Einrichtungen bestehen aus Metall, bevorzugt aus Edelstahl, was es erlaubt, den für Pharmabereiche vorgeschriebenen, hygienischen Standards auf Dauer problemlos zu genügen und zugleich eine elektrostatische Neutralisierung der Medikamentkapseln zu erreichen. Für die Funktionssicherheit auch der Verpackungsautomaten und die Vermeidung von Bränden ist das von großem Vorteil. Elektrostatische Kräfte können nämlich dazu führen, dass sich eine große Anzahl von Medikamentenkapseln zu einer Kette zusammenschließt, was die notwendige Separierung behindert.The sieve drum and the devices connected to it are made of metal, preferably of stainless steel, which makes it possible to easily meet the hygienic standards prescribed for pharmaceutical areas in the long term and at the same time to achieve an electrostatic neutralization of the medicament capsules. For the reliability of the packaging machine and the prevention of fire that is of great advantage. Electrostatic forces namely, can cause a large number of drug capsules to form a chain, which hinders the necessary separation.
Durch den frei zugänglichen Innenraum der Siebtrommel können die zu kontrollierenden Medikamentenkapseln auf eine besonders einfache Weise zugeführt, fehlerhafte Medikamentenkapseln einfach abgeführt und eventuelle Störungen leicht behoben werden. Auch ist die Reinigung und der Austausch einer Siebtrommel gegen eine andere ist besonders einfach möglich. Da die Siebtrommel lediglich auf einem Paar motorisch angetriebener Rollen gelagert ist, werden elektrische Anschlüsse oder ähnliches beim Austausch einer Siebtrommmel nicht berührt. Die Umstellung auf Medikamentenkapseln eines abweichenden Durchmessers ist dadurch werkzeuglos und auch von ungelernten Kräften durchführbar.Due to the freely accessible interior of the sieve drum, the drug capsules to be controlled can be supplied in a particularly simple manner, defective drug capsules can be easily removed, and possible malfunctions can be easily remedied. Also, the cleaning and replacement of a screen drum against another is particularly easy. Since the screen drum is mounted only on a pair of motor-driven rollers, electrical connections or the like are not affected when replacing a Siebtrommmel. The conversion to drug capsules of a different diameter is thus tool-free and feasible even by unskilled workers.
Die Ausgestaltung nach Anspruch 2 bietet den Vorteil, dass die Umwälzung der im Innenraum der Siebtrommel enthaltenen Medikamentkapseln nicht gleichmäßig rollend, sondern bei fortschreitender Drehbewegung der Siebtrommel über unterschiedliche Neigungswinkel der jeweils unten befindlichen, ebenen Platten mit unterschiedlichen Geschwindigkeiten erfolgt. Dies begünstigt eine schnelle und korrekte, vertikale Einführung der zu prüfenden Medikamentenkapseln in die Bohrungen der Siebtrommel und damit einen besonders zügigen Arbeitsablauf.The embodiment according to
Die Ausgestaltung nach Anspruch 3 bietet den Vorteil, dass die einzelnen Platten sehr leicht und manuell in Längsrichtung aus ihrer Führung herausgezogen, gereinigt oder ausgetauscht werden können. Für die Verwendung der Vorrichtung in niedrigen Räumen ohne Kraneinrichtung ist das von großem Vorteil.The embodiment according to
Anspruch 4 bietet den Vorteil, parallel zur Arretierung der Platten zugleich der Innenraum der Siebtrommel in Längsrichtung im erforderlichen Ausmaß begrenzt wird. Dies beschleunigt die Wiedererlangung der Betriebsfähigkeit im Anschluss an den Austausch einer oder mehrerer Platten.Claim 4 offers the advantage, parallel to the locking of the plates at the same time the interior of the screening drum is limited in the longitudinal direction to the extent required. This speeds up the recovery of operability following the replacement of one or more disks.
Die Bauform der Platten nach Anspruch 5 gestattet es, die Platten auf eine besonders einfache und kostengünstige Weise herzustellen, gestapelt zu lagern und einzubauen.The design of the plates according to
Die Bauform nach Anspruch 6 bietet eine besonders einfache Möglichkeit an, fehlerhafte Medikamentenkapseln vollzählig aus der Vorrichtung auszuscheiden und gesondert aufzufangen. Durch die sofortige Entfernung von fehlerhaften Medikamentenkapseln steht außerdem immer eine größtmögliche Anzahl von betriebsbereiten und unverstopften Bohrungen für die weitere Kontrolle zu Verfügung.The design according to claim 6 offers a particularly simple way to eliminate defective drug capsules completely from the device and collect separately. In addition, the immediate removal of defective drug capsules always provides a maximum number of operational and unclogged holes for further control.
Durch die Ausgestaltung nach Anspruch 7 ist sichergestellt, dass fehlerhafte Medikamentenkapseln unter allen Umständen rückstandslos und zuverlässig entfernt werden.The embodiment according to
Die Ausgestaltung nach Anspruch 8 gewährleistet eine vollständige Entfernung aller eventuell in einer Platte steckengebliebenen Medikamentenkapseln ohne gesonderte Kontrolle.The embodiment according to claim 8 ensures a complete removal of all possibly stuck in a plate drug capsules without separate control.
Die Ausgestaltung nach Anspruch 9 gewährleistet die Entfernung aller eventuell in einer Platte stecken gebliebenen Medikamentenkapseln in der kürzestmöglichen Zeit.The embodiment according to claim 9 ensures the removal of all possibly stuck in a plate drug capsules in the shortest possible time.
Die Ausgestaltung nach Anspruch 10 ermöglicht es, schadhafte Dorne kostengünstig auszutauschen.The embodiment according to claim 10 makes it possible to exchange defective spikes cost.
Die Ausgestaltung nach Anspruch 11 bietet den Vorteil, dass andauernd eine völlige Betriebs- und Funktionssicherheit der Vorrichtung gewährleistet ist, ohne dass es der Zuziehung von Fachpersonal bedarf.The embodiment according to claim 11 offers the advantage that permanently a complete operational and functional safety of the device is ensured without the need for Zuziehung of specialized personnel.
Die Ausgestaltung nach Anspruch 12 gewährleistet eine besonders zuverlässige Durchführung des Kontrollvorgangs und insbesondere eine gleichmäßige und zuverlässige Einführung der Medikamentenkapseln in die Bohrungen. Durch den gleichmäßigen und ganz allmählichen Übergang des größten in den kleinsten Durchmesser der Bohrungen werden außerdem eventuelle Beschädigungen der Medikamentenkapseln ausgeschlossen. Ferner wird sichergestellt, dass sich alle kritischen Medikamentenkapseln unabhängig von der Art der jeweiligen Deformierung sicher in den Bohrungen verklemmen und sicher ausgeschieden werden können.The embodiment according to claim 12 ensures a particularly reliable implementation of the control process and in particular a uniform and reliable introduction of the drug capsules in the holes. Due to the uniform and very gradual transition of the largest in the smallest diameter of the holes also any damage to the drug capsules are excluded. It also ensures that all critical drug capsules can securely clamp in the holes regardless of the nature of the deformity and can be safely eliminated.
Der Innendurchmesser der Bohrungen ist an sich willkürlich und frei festlegbar. Die Ausgestaltung nach Anspruch 13 bietet hiervon ausgehend den Vorteil, dass die kontrollierten Medikamentenkapseln unter Vermeidung von unnötigen Erschwernissen bei der Kontrolle störungsfrei in allen gängigen Verpackungsautomaten verarbeitbar sind und deren Führungen nicht blockieren.The inner diameter of the holes is in itself arbitrary and freely definable. The embodiment according to claim 13 offers on this basis the advantage that the controlled drug capsules are trouble-free in all current packaging machines processable while avoiding unnecessary difficulties in the control and their guides do not block.
Die Ausgestaltung nach Anspruch 14 begünstigt eine störungsfreie Kontrolle noch mehr insofern, als die Innenseite der Siebtrommel praktisch in allen Teilbereichen durch scharfkantige Linienzüge gebildet ist, in denen sich die benachbarten Bohrungen mit ihren trichterartigen Einlauföffnungen gegenseitig nach Art eines Wabenmusters begrenzen. Durch den Wegfall von ebenen Flächen, die sich quer zur Längsrichtung der Bohrungen erstrecken, ist es daher ausgeschlossen, dass sich Medikamentkapseln im Inneren der Siebtrommel flach ablagern, kumulieren und dadurch nicht in die Bohrungen gelangen. Für einen störungsfreien Betrieb ist das von großem Vorteil.The embodiment according to claim 14 favors a trouble-free control even more so far, as the inside of the screen drum is formed in almost all areas by sharp-edged polylines, in which the adjacent holes with their funnel-like inlet openings each other limit in the manner of a honeycomb pattern. By eliminating flat surfaces which extend transversely to the longitudinal direction of the bores, it is therefore impossible for medicament capsules to be deposited flat in the interior of the sieve drum, to accumulate and thereby not get into the bores. This is a great advantage for trouble-free operation.

Die Wandung der Siebtrommel 2 weist eine Vielzahl von radial nach innen trichterförmig erweiterten Bohrungen 3 eines willkürlich festgelegten, kleinsten Durchmessers auf, die die Wandung der Siebtrommel 2 radial durchbrechen. Die Siebtrommel 2 umschließt einen zumindest von einer Stirnseite frei zugänglichen, nabenlosen Innenraum 4. Die Wandung der Siebtrommel 2 ist durch in Umfangfangsrichtung aufeinanderfolgende, identisch ausgebildete, ebene Platten 5 gebildet, die in Umfangsrichtung beiderseits durch Nuten begrenzt und mit den Nuten auf Führungsbolzen 2.3 der stirnseitigen Stirnflansche 2.1, 2.4 der Siebtrommel 2 aufgefädelt sind, die sich parallel zur Rotationsachse 2.2 der Siebtrommel 2 erstrecken.The wall of the
In den Innenraum 4 der Siebtrommel 2 greift ein Trichter 6 ein, der nach oben geöffnet ist und der unten durch eine Rutsche gebildet ist, über die von oben in den Trichter 6 hineinfallende Medikamentkapseln 1 schräg aus dem Innenraum entfernt werden können.Into the interior 4 of the

Unter der Siebtrommel 2 ist eine Aufnahmeinrichtung für "gute" Medikamentenkapseln angeordnet, da dazu bestimmt ist, fehlerfreie Medikamentenkapseln 1, die die Bohrungen 3 der Siebtrommel 2 passiert haben, den nicht dargestellten Verpackungsautomaten zuzuführen.Under the
Die Siebtrommel 2 ist in Längsrichtung durch Stirnflansche 2.1 begrenzt, wobei die Stirnflansche 2.1, 2.4 durch sich parallel zur Rotationsachse 2.2 erstreckende, gleichmäßig in Umfangsrichtung verteilte Führungsbolzen 2.3 verbunden sind und wobei die Platten 5 auf den Führungsbolzen 2.3 gelagert sind. Die Platten 5 sind parallel zur Achsrichtung herausnehmbar auf den Führungsbolzen 2.3 gelagert und durch einen auf die Führungsbolzen 2.3 aufsteckbaren Stirnflansch 2.5 arretierbar. Die Platten 5 sind in Umfangsrichtung beiderseits durch sich parallel zur Rotationsachse erstreckende Führungsnuten begrenzt und mit den Führungsnuten auf die Führungsbolzen 2.3 aufgeschoben.The
Die Stirnflansche 2.1, 2.4 sind im Bereich des Außenumfangs kreisförmig begrenzt und auf einem motorisch angetriebenen Rollenpaar 2.6 gelagert. Das Rollenpaar 2.6 und die gesamte Vorrichtung bestehen aus Metall, vorliegend aus Edelstahl. Dadurch ist eine Reinigung leicht möglich. Elektrostatische Kräfte können leicht abgeführt werden.The end flanges 2.1, 2.4 are limited in the region of the outer circumference circular and mounted on a motor-driven roller pair 2.6. The pair of rollers 2.6 and the entire device are made of metal, in this case made of stainless steel. This makes cleaning easy. Electrostatic forces can be dissipated easily.
Eine Lagerung der Siebtrommel 2 auf gummierten Rollen ist gleichfalls möglich und trägt dazu bei, den Geräuschpegel der rotierenden Siebtrommel 2 zu senken. Für die Ableitung elektrostatischer Aufladungen müssen dann separate Vorkehrungen getroffen werden und beispielsweise Schleifkontakte an der Siebtrommel 2 angebracht werden.A storage of the
Die Rotation der Siebtrommel 2 ist computergesteuert vorübergehend zum Stillstand bringbar, wenn sich jeweils eine der Platten 5 oberhalb des im Innenraum der Siebtrommel angeordneten, nach oben geöffneten Trichters 6 befindet, wobei mechanische Mittel 7 vorhanden sind, durch die die jeweils in den Bohrungen 3 der Siebtrommel 2 verklemmten Medikamentenkapseln 1 aus den Bohrungen 3 vertikal nach unten ausstoßbar und in den Trichter 6 abwerfbar sind. Danach rotiert die Siebtrommel 2 erneut, bis sich eine Platte 5 oberhalb des Trichters 6 befindet.The rotation of the
Die das Ausstoßen der fehlerhaften Medikamentenkapseln 1 aus den Bohrungen 3 bewirkenden Mittel 7 sind durch Dorne gebildet, die vertikal von oben radial nach innen in die Bohrungen 3 einführbar sind.The ejection of the
Der Trichter 6 untergreift jeweils zugleich alle Bohrungen 3 einer Platte 5 und jeder der in der Platte 5 enthaltenen Bohrungen 3 ist ein separater Dorn zugeordnet, wie in
Alle Dorne sind an einem gemeinsamen Träger 7.1 befestigt und gemeinsam und parallel zueinander in alle Bohrungen 3 einer Platte 5 zugleich absenkbar und daraus entnehmbar. Die betreffende Platte 5 ist dadurch anschließend wieder in vollem Umfang für die Durchführung weiterer Kontrollvorgänge verwendbar. Die Dorne sind lösbar an dem Träger 7.1 befestigt, beispielsweise durch eine Schraubverbindung. Sie können dadurch im Falle einer Beschädigung problemlos ersetzt werden.All mandrels are attached to a common support 7.1 and at the same time lowered together and parallel to each other in all

Die Bohrungen 3 haben einen in Richtung der Achse 2.2 radial nach innen nach Art eines Trompetentrichters kantenfreien, abgerundet erweiterten Innendurchmesser. Dadurch fallen die auf die Innenwandung auftreffenden Medikamentenkapseln leicht in die Bohrungen 3 hinein und gegebenenfalls parallel zu ihrer Längsrichtung hindurch.The
Die Bohrungen 3 haben einen kleinsten Innendurchmesser, der 0,5 bis 1,0 mm größer ist als der Nenndurchmesser der zu prüfenden Medikamentenkapseln 1. Dies gewährleistet einen sicheren Betrieb aller bekannten Verpackungsautomaten.The
Der gegenseitige Abstand sich parallel zueinander erstreckender Schnittkanten 5.1 eines jeden Trichters der Bohrungen 3 ist größer als die Länge der jeweils zu prüfenden Medikamentenkapseln 1. Dabei genügt ein geringes Übermaß von 10 bis 50% um den Durchfluss der Medikamentenkapseln deutlich zu beschleunigen. Außerdem ist es durch den völligen Wegfall von ebenen Innenflächen der Siebtrommel in den zentralen Bereichen der Platten 5 kaum möglich, dass sich Medikamentenkapseln im Inneren der Siebtrommel kumulieren und nicht in die Bohrungen 3 gelangen. Die Schnittkanten 5.1 haben, bezogen auf die Oberfläche der Platten 5, einen uneben gewellten Verlauf. Dies trägt dazu bei, die auf die Oberfläche auftreffenden Medikamentenkapseln 1 in die Bohrungen zu lenken und der Kontrolle zuzuführenThe mutual distance parallel to each other extending cutting edges 5.1 of each funnel of the
