Definitions
- the invention relates to the design of a one-piece sealing strip for the housing of a tablet press.
- Tablet presses regularly have a housing with four side walls surrounding the press, in which windows are arranged which can be pivoted and locked against a window frame.
- flaps are often provided beneath such a protective hood in the area of the drive units of the press, which flaps can be opened for better access to machine units.
- Air conditioning of the room in which the tablet press is installed can be omitted if the tablet press is manufactured under vacuum, which is maintained in the housing. Such operation, however, requires complete sealing, since otherwise air is sucked into the press chamber from the outside with the slightest leak. Such leaks can be expected, however, if the protective cover is provided with relatively large pivotable windows, which are necessary for monitoring the press and its maintenance.
- a sealing strip is known with two sealing lips arranged in a V-shape over a terminal strip. These sealing lips are intended for inserting the sealing strip into a groove in a wall. They are pressed together. So they are not used to abut a single flat plate for the purpose of sealing, but only for insertion into a groove in one part while the terminal block is inserted in another groove in another part. The lips therefore do not serve as a seal in themselves, but rather to hold the sealing strip in a wall part. It is therefore not possible to create a chamber between the sealing lips in which an air overpressure is to be generated in order to prevent the penetration of outside air into the interior of a sealed room. The same applies to a sealing strip according to DE-U-8616133, which is formed in several parts and has two lips, which are not bent apart for the purpose of sealing a wall plate.
- the object of the invention is to provide a sealing strip for the housing of a tablet press, with which the special aforementioned requirements must be taken into account.
- the sealing strip on the top of a central web carries two arranged on its outer edges, obliquely outward and outwardly tapering sealing lips that are bent outwards laterally by a plate to be sealed, and on the underside of the central web carries a centrally arranged terminal strip with laterally arranged webs, which is narrower than the distance between the sealing lips. This ensures that when a plate is pivoted towards the lips, they are bent outwards, thereby providing a seal for the space between the plates.
- a chamber between the two lips is maintained, which is to be pressurized with air, so that a vacuum can be maintained on the one hand, but on the other hand contamination in the manner of an air passage from the outside of the housing into the pressing chamber and so that pollution of the air in the pressing room of the tabletting machine is prevented.
- the sealing strip thus not only seals one plate from another, but also gives the additional possibility of artificially maintaining an excess air pressure in the chamber between the two sealing lips.
- the sealing strip 1 shown in the drawing has two sealing lips 3 which are oriented obliquely to one another and which are tapered towards the outside.
- This sealing strip is carried by a central web 5, directed obliquely outwards from it while sitting at its edge are.
- the central web 5 is provided on the two edges of its underside with a support lip 11, with which it is supported on a supporting part such as a glass plate 15.
- the central web 5 carries a clamping bar 7 which is provided on its two outer sides with webs 9 which are oriented obliquely to the central web and serve to clamp the clamping bar 7 in a groove 8.
- the extent of this tension is further increased by the arrangement of a chamber 13 running longitudinally in the terminal strip 7, which is compressed when the sealing strip 1 is used, since the strip 1 consists of an elastic material, in particular of silicone rubber.

Description
Gegenstand der Erfindung bildet die Ausgestaltung einer einteiligen Dichtungsleiste für das Gehäuse einer Tablettenpresse.The invention relates to the design of a one-piece sealing strip for the housing of a tablet press.
Tablettenpressen weisen regelmäßig ein Gehäuse auf mit vier die Presse umfassenden Seitenwänden, in denen Fenster angeordnet sind, die schwenkbar und gegen einen Fensterrahmen verschließbar sind. Darüber hinaus sind unterhalb einer solchen Schutzhaube im Bereich der Antriebsaggregate der Presse häufig Klappen vorgesehen, welche zu öffnen sind für eine bessere Zugänglichkeit zu Aggregaten der Maschine.Tablet presses regularly have a housing with four side walls surrounding the press, in which windows are arranged which can be pivoted and locked against a window frame. In addition, flaps are often provided beneath such a protective hood in the area of the drive units of the press, which flaps can be opened for better access to machine units.
Um ein Verschmutzen des Preßraumes von Tablettenpressen durch eintretende Umluft aber auch ein Austreten von Tablettenstaub in den Aufstellungsraum zu verhindern ist es bekannt, die schwenkbaren Fenster einer Schutzhaube oder andere Platten des Gehäuses mit Dichtungen zu versehen. Selbst wenn solche Dichtungen vorgesehen sind, besteht bei bekannten Tablettenpressen dennoch die Gefahr, daß nur bei geringfügigen Undichtigkeiten Luft aus dem Aufstellungsraum in den von dem Gehäuse umschlossenen Preßraum eindringt. Da die Herstellung von Tabletten vielfach nur unter klimatisch sauberer Luft erfolgen darf, hat man sich deshalb bereits gezwungen gesehen, die gesamte Luft des Aufstellungsraumes zu klimatisieren, was verhältnismäßig aufwendig ist.In order to prevent the pressing chamber of tablet presses from being contaminated by incoming air, but also to prevent tablet dust from escaping into the installation space, it is known to provide the pivotable windows of a protective hood or other plates of the housing with seals. Even if such seals are provided, there is still the danger in known tablet presses that air only penetrates into the press chamber enclosed by the housing from the installation space in the event of slight leaks. Since the manufacture of tablets many times only under climatically clean air is allowed, one has therefore already been forced to air-condition the entire air in the installation room, which is relatively expensive.
Eine Klimatisierung der Luft des Aufstellungsraumes der Tablettenpresse kann entfallen, wenn die Herstellung der Tablettenpresse unter Vakuum erfolgt, das im Gehäuse aufrechterhalten wird. Ein derartiger Betrieb setzt jedoch eine vollkommene Abdichtung voraus, da anderenfalls bei geringsten Undichtigkeiten Luft von außen in den Preßraum hinein gesogen wird. Mit derartigen Undichtigkeiten ist aber zu rechnen, wenn die Schutzhaub mit relativ großen schwenkbaren Fenstern versehen ist, die für die Beobachtung der Presse und ihre Wartung notwendig sind.Air conditioning of the room in which the tablet press is installed can be omitted if the tablet press is manufactured under vacuum, which is maintained in the housing. Such operation, however, requires complete sealing, since otherwise air is sucked into the press chamber from the outside with the slightest leak. Such leaks can be expected, however, if the protective cover is provided with relatively large pivotable windows, which are necessary for monitoring the press and its maintenance.
Nach der US-A-2345273 ist eine Dichtungsleiste bekannt mit zwei über einer Klemmleiste v-förmig angeordneten Dichtungslippen. Diese Dichtungslippen sind bestimmt für das Einstecken der Dichtungsleiste in eine Nut einer Wand. Dabei werden sie zusammengepreßt. Sie dienen also nicht der Anlage an einer einzigen ebenen Platte zum Zwecke der Abdichtung, sondern allein dem Einschub in eine Nut eines Teiles während die Klemmleiste in einer anderen Nut eines anderen Teiles eingeschoben ist. Die Lippen dienen damit nicht der Abdichtung ansich, sondern der Halterung der Dichtungsleiste in einem Wandteil. Damit läßt sich nicht eine Kammer schaffen zwischen den Dichtungslippen in der ein Luftüberdruck zu erzeugen ist, um durch diesen unterstützend das Eindringen von Außenluft in das Innere eines abgedichteten Raumes zu verhindern. Gleiches gilt für eine Dichtungsleiste nach der DE-U-8616133, die mehrteilig ausgebildet ist und zwei Lippen aufweist, welche nicht zum Zwecke der Abdichtung einer Wandplatte auseinandergebogen werden.According to US-A-2345273, a sealing strip is known with two sealing lips arranged in a V-shape over a terminal strip. These sealing lips are intended for inserting the sealing strip into a groove in a wall. They are pressed together. So they are not used to abut a single flat plate for the purpose of sealing, but only for insertion into a groove in one part while the terminal block is inserted in another groove in another part. The lips therefore do not serve as a seal in themselves, but rather to hold the sealing strip in a wall part. It is therefore not possible to create a chamber between the sealing lips in which an air overpressure is to be generated in order to prevent the penetration of outside air into the interior of a sealed room. The same applies to a sealing strip according to DE-U-8616133, which is formed in several parts and has two lips, which are not bent apart for the purpose of sealing a wall plate.
Aufgabe der Erfindung ist es, eine Dichtungsleiste für das Gehäuse einer Tablettenpresse zu schaffen, mit welcher den besonderen vorgenannten Anforderungen Rechnung zu tragen ist. Nach der Erfindung ist dafür vorgesehen, daß die Dichtungsleiste auf der Oberseite eines Mittelsteges zwei an seinen Außenrändern angeordnete, schräg nach außen gerichtete und sich nach außen verjüngende Dichtungslippen trägt, die seitlich nach außen durch eine abzudichtende Platte auszubiegen sind, und auf der Unterseite des Mittelsteges eine mittig angeordnete Klemmleiste mit seitlich angeordneten Stegen trägt, die schmaler ist als der Abstand der Dichtungslippen. Dadurch wird erreicht, daß beim Heranschwenken einer Platte auf die Lippen diese nach außen gebogen werden, wobei sie eine Abdichtung ergeben für den Zwischenraum zwischen den Platten. Hierbei bleibt jedoch eine Kammer zwischen den beiden Lippen aufrecht erhalten, die mit Luft zu beaufschlagen ist, so daß auf der einen Seite ein Vakuum aufrecht erhalten werden kann, andererseits jedoch eine Contamination in der Art eines Luftdurchtrittes von der Außenseite des Gehäuses in den Pressraum und damit eine Verschmutzung der Luft in dem Pressraum der Tablettiermaschine verhindert wird. Die Dichtungsleiste dichtet damit nicht nur eine Platte gegenüber einer anderen ab, sondern gibt die zusätzliche Möglichkeit, in der Kammer zwischen den beiden Dichtungslippen künstlich einen Überdruck an Luft aufrecht zu erhalten.The object of the invention is to provide a sealing strip for the housing of a tablet press, with which the special aforementioned requirements must be taken into account. According to the invention it is provided that the sealing strip on the top of a central web carries two arranged on its outer edges, obliquely outward and outwardly tapering sealing lips that are bent outwards laterally by a plate to be sealed, and on the underside of the central web carries a centrally arranged terminal strip with laterally arranged webs, which is narrower than the distance between the sealing lips. This ensures that when a plate is pivoted towards the lips, they are bent outwards, thereby providing a seal for the space between the plates. Here, however, a chamber between the two lips is maintained, which is to be pressurized with air, so that a vacuum can be maintained on the one hand, but on the other hand contamination in the manner of an air passage from the outside of the housing into the pressing chamber and so that pollution of the air in the pressing room of the tabletting machine is prevented. The sealing strip thus not only seals one plate from another, but also gives the additional possibility of artificially maintaining an excess air pressure in the chamber between the two sealing lips.
Ein Ausführungsbeispiel der Erfindung ist nachstehend unter Bezugnahme auf eine Zeichnung erläutert.An embodiment of the invention is explained below with reference to a drawing.
Die in der Zeichnung wiedergegebene Dichtungsleiste 1 weist zwei schräg zueinander ausgerichtete Dichtungslippen 3 auf, die sich nach außen verjüngend ausgebildet sind. Diese Dichtungsleiste sind getragen von einem Mittelsteg 5, von sie an seinem Rand sitzend schräg nach außen gerichtet sind. Der Mittelsteg 5 ist an den beiden Rändern seiner Unterseite jeweils mit einer Stützlippe 11 versehen, mit denen er sich auf einem tragenden Teil wie beispielsweise einer Glasplatte 15 abstützt. In der Mitte auf seiner Unterseite trägt der Mittelsteg 5 eine Klemmleiste 7, die an ihren beiden Außenseiten mit Stegen 9 versehen ist, welche schräg zum Mittelsteg ausgerichtet sind und dazu dienen, die Klemmleiste 7 in einer Nut 8 festzuspannen. Das Ausmaß dieser Spannung wird noch vergrößeert durch die Anordnung einer in der Klemmleiste 7 längsverlaufenden Kammer 13, die beim Einsatz der Dichtungsleiste 1 zusammengedrückt wird, da die Leiste 1 aus einem elastischen Material, insbesondere aus Silikonkautschuk besteht.The sealing strip 1 shown in the drawing has two sealing lips 3 which are oriented obliquely to one another and which are tapered towards the outside. This sealing strip is carried by a
