Abstract

A conveyor for testing successive plain or filter cigarettes or other rod-shaped smokers' products having non-circular (such as oval) cross-sectional outlines employs a rotary drum-shaped conveyor for sidewise transport of smokers' products toward, through and beyond a station where the products are tested by streams of a gaseous fluid entering the products at one axial end and issuing from satisfactory products at the other axial end. The end portions of the products are sealingly received in complementary sockets of elastically deformable sealing sleeves which are connected to their tubular fluid-conveying carriers in a manner to ensure that each sleeve remains in a selected position for optimum testing of the products. For example, each sleeve can be form-lockingly coupled to its carrier in such a way that the sleeve is held against any appreciable angular and/or axial movement relative to the carrier when the conveyor transports smokers' products but that the sleeve can be detached from the carrier, in response to adequate deformation, for the purpose of inspection, cleaning and/or replacement.

Description

Die Erfindung betrifft eine Dichtung für Enden von unrunden stabförmigen Artikeln der tabakverarbeitenden Industrie, die zumindest teilweise aus gummielastischem Material bestehend entfernbar auf einem an einem Prüfförderer angeordneten Träger sitzt, und durch die Prüfgas, vorzugsweise Prüfluft, in das Innere der Artikel einleitbar ist.The invention relates to a seal for ends of non-circular rod-shaped articles the tobacco processing industry, which is at least partially made of rubber-elastic Material consisting removably on a carrier arranged on a test conveyor sits, and through the test gas, preferably test air, into the interior of the article can be initiated.

Unter dem Begriff "gummielastisches Material" wird Gummi (Latex), aber insbesondere auch entsprechend elastischer verschleißfester Kunsstoff verstanden.The term "rubber-elastic material" is rubber (latex), but in particular also understood according to elastic wear-resistant plastic.

Der Begriff "stabförmige Artikel der tabakverarbeitenden Industrie" umfaßt stabförmige Rauchartikel wie Zigaretten, Zigarillos oder Zigarren mit und ohne Filter, die im wesentlichen aus Tabak oder einem sonstigen rauchbaren Material bestehen, sowie stabförmige Filterstäbe.The term "rod-shaped articles of the tobacco processing industry" includes rod-shaped Smoking articles such as cigarettes, cigarillos or cigars with and without filters that consist essentially of tobacco or other smokable material, as well as rod-shaped filter rods.

Es ist bekannt, zum Prüfen von Zigaretten in diese Prüfluft einzuleiten und aus sich einstellenden pneumatischen Werten auf Fehler der Umhüllung (Löcher, fehlerhafte Ventilationszonen) und/oder Füllung zu schließen. Hierzu wird die Prüfluft in der Regel über mindestens eine ein Ende einer Zigarette gegen die Umgebung abdichtende Dichtung aus gummielastischem Material zugeführt und in das Innere der Zigarette geleitet. An dem anderen Ende der Zigarette kann ebenfalls eine Dichtung zur Endenabdichtung vorgesehen sein, die z. B. die Prüfluft oder den Druck der Prüfluft einer Zigarette zu einem Meßwertgeber leitet. Die Dichtungen sind an einem Prüfförderer befestigt und werden durch axiales Verschieben in ihre Prüfpositionen und nach Durchführung der Prüfung in ihre Ausgangsstellungen verbracht. Ein Prüfförderer (Prüftrommel) mit gummielastischen Dichtungen für beide Enden von Zigaretten ist in der US-PS 3 948 084 detailliert dargestellt und beschrieben. Bei der Prüfung von unrunden Artikeln, insbesondere von sogenannten ovalen Zigaretten, sind die Dichtungen entsprechend unrund geformt. Ihre Lagen auf dem Prüfförderer entsprechen den Lagen der Zigaretten beim Prüfen. Bei der Montage solcher Dichtungen auf Trägern, die sie halten, muß darauf geachtet werden, daß die Dichtungen exakt auf die Zigaretten ausgerichtet sind. Ist diese Forderung bei der Erstausrichtung einer Prüftrommel mit relativ vielen Dichtungen noch zu erfüllen, so können im Betrieb, bei dem die Dichtungen mit der Zeit verschleißen und betriebsmäßig ausgetauscht werden müssen, Schwierigkeiten entstehen, insbesondere wenn ungeschultes Personal die Auswechslung der Dichtungen vornehmen muß.It is known to introduce cigarette into this test air and by itself adjusting pneumatic values for errors in the coating (holes, faulty Ventilation zones) and / or filling. For this purpose, the test air in the Usually have at least one end of a cigarette sealing against the environment Seal made of elastic material and fed into the interior of the Headed cigarette. At the other end of the cigarette there can also be a seal be provided for end sealing, the z. B. the test air or the pressure the test air of a cigarette leads to a transmitter. The seals are on attached to a test conveyor and are moved axially into their test positions and returned to their starting positions after the test. A test conveyor (test drum) with rubber-elastic seals for both Cigarette ends are shown and described in detail in U.S. Patent No. 3,948,084. When checking non-round articles, especially so-called oval cigarettes, the seals are shaped accordingly out of round. Your locations on the test conveyor correspond to the positions of the cigarettes during the test. In the Assembly of such seals on supports that hold them, care must be taken that the seals are exactly aligned with the cigarettes. Is this requirement when first aligning a test drum with a relatively large number of seals can be met in operation where the seals wear out over time and need to be replaced operationally, difficulties arise, in particular if untrained personnel replace the seals got to.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, die Montage von unrunden Dichtungen für unrunde stabförmige Artikel zu erleichtern und Fehlmontagen auszuschließen.The object underlying the invention is the assembly of non-circular Seals for non-round rod-shaped articles to facilitate and incorrect assembly excluded.

Gemäß der Erfindung läßt sich dies dadurch erreichen, daß die Dichtung im Bereich des Trägers eine Form aufweist, durch die sie in einer definierten Lage zum Prüfförderer oder den auf diesem befindlichen Zigaretten auf den Träger aufbringbar ist. According to the invention, this can be achieved in that the seal in the area of the carrier has a shape by which it is in a defined position for Test conveyor or the cigarettes located thereon can be applied to the carrier is.

Die Erfindung ist besonders vorteilhaft bei Dichtungen für Artikel mit ovalem Querschnitt, die in ebenfalls oval ausgebildete Aufnahmen der Dichtungen aufgenommen werden.The invention is particularly advantageous in the case of seals for articles with an oval cross section, which is also included in oval seals of the seals become.

Gemäß einer bevorzugten Ausgestaltung der Erfindung weist der Träger einen Bereich auf, der mit einem Positionierungsprofil für die entsprechend geformte Dichtung versehen ist. Diesem Bereich kann in vorteilhafter Weiterbildung der Erfindung in Richtung auf den Prüfförderer ein weiterer Klemmbereich mit kleinerem Durchmesser nachgeordnet sein. Das Positionierungsprofil des Trägers kann gemäß der Erfindung in einfacher Weise als nutförmige Ausnehmung, dasjenige der Dichtung als darin aufgenommener Steg, der also von der Innenseite der Dichtung sich nach innen erstreckt, ausgebildet sein. Die Positionierung einer Dichtung auf ihrem Träger ist nicht auf das dargestellte Beispiel beschränkt. So kann beispielsweise auch der Träger mit einem Steg, die Dichtung mit einer nutförmigen Ausnehmung versehen sein. Außerdem sind weitere im Maschinenbau bekannte Positioniervorrichtungen, soweit sie sich bei gummielastischen Stoffen eignen, anwendbar. So kann in einfacher Weise Träger an einer Stelle abgeflacht sein, während die Innenseite der Dichtung einen entsprechend geformten Wulst aufweist.According to a preferred embodiment of the invention, the carrier has an area on that with a positioning profile for the appropriately shaped seal is provided. This area can be in an advantageous development of the invention another clamping area with a smaller diameter in the direction of the test conveyor be subordinate. The positioning profile of the carrier can be according to the Invention in a simple manner as a groove-shaped recess, that of the seal as a web accommodated therein, that is to say from the inside of the seal extends inside, be formed. The positioning of a seal on its carrier is not limited to the example shown. For example the carrier with a web, the seal with a groove-shaped recess his. In addition, other positioning devices known in mechanical engineering are insofar as they are suitable for rubber-elastic materials, applicable. So in simply be flattened at one point while the inside of the beam Seal has a correspondingly shaped bead.

Die Dichtung gemäß der Erfindung weist den Vorteil auf, daß die Montage auf dem Träger erleichtert wird und daher schnell ausgeführt werden kann, und daß eine Montage in einer Fehllage praktisch ausgeschlossen ist. Damit wird verhindert, daß ovale Zigarettenenden z. B. mit ihren großen Achsen auf den Bereich der kleinen Achse einer Dichtung treffen, wodurch Dichtung und/oder Zigarettenenden beschädigt werden könnten. The seal according to the invention has the advantage that the assembly on the Carrier is facilitated and can therefore be carried out quickly, and that a Assembly in an incorrect position is practically impossible. This prevents oval cigarette ends e.g. B. with their large axes in the area of small ones Hit the axis of a seal, causing damage to the seal and / or cigarette ends could become.

Die Erfindung wird in der Zeichnung anhand eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail in the drawing using an exemplary embodiment.

Figur 1 zeigt eine Prüftrommel 1 mit Aufnahmen 2, in denen ovale Zigaretten 3 aufeinanderfolgend zu dem Prüfbereich 4 zugefördert werden. In der Figur ist nur eine Zigarette 3 schematisch dargestellt. Zu Beginn des Prüfbereichs werden Dichtungen 6 mit ebenfalls ovalen Aufnahmen 7 axial auf die Enden 8 der Zigaretten 3 zubewegt. In Figur 1 sind nur die Dichtungen 6 an einem Ende 9 der Prüftrommel dargestellt. An dem anderen weggelassenen Ende 10 der Prüftrommel 1 können in gleicher Weise Dichtungen mit ovalen Aufnahmen angeordnet sein, deren Aufnahmen die anderen Enden 5 der Zigaretten 3 aufnehmen können.FIG. 1 shows a test drum 1 with receptacles 2 in which oval cigarettes 3 are successively conveyed to the test area 4. In the figure is only a cigarette 3 is shown schematically. At the beginning of the test area Seals 6 with also oval receptacles 7 axially on the ends 8 of the cigarettes 3 moves. In Figure 1 there are only the seals 6 at one end 9 of the test drum shown. At the other omitted end 10 of the test drum 1 can be arranged in the same way seals with oval receptacles whose Recordings can take the other ends 5 of the cigarettes 3.

Die Dichtungen weisen Öffnungen 11 auf, durch die in der Prüfstellung der Dichtungen (Figur 3) Prüfluft unter Druck in die Zigarettenenden 8 eingeleitet oder ausgeleitet wird, z. B. zu einer elektrischen oder pneumatischen Prüfvorrichtung. Die Prüfung erfolgt während des Durchlaufs der Zigaretten 3 durch den Prüfbereich 4. Am Ende des Prüfbereichs 4 werden die Dichtungen 6 axial von den Zigaretten 3 wegbewegt, so daß diese von den Dichtungen freikommen und in ihren Aufnahmen 2 abgefördert werden können.The seals have openings 11 through which the seals are in the test position (Figure 3) Test air introduced or discharged under pressure in the cigarette ends 8 will, e.g. B. an electrical or pneumatic test device. The Testing takes place during the passage of the cigarettes 3 through the test area 4. At the end of the test area 4, the seals 6 are axially removed from the cigarettes 3 moved away so that they come free from the seals and in their receptacles 2 can be removed.

Figur 2 stellt ein ovales Dichtungsende 8 in kurzer Entfernung von der ebenfalls ovalen Aufnahme 7 einer Dichtung 6 dar. Die Aufnahme 7 der Dichtung 6 läßt die Öffnung 11 für die Prüfluft erkennen. Die Dichtung 6 ist bevorzugt auch im Bereich ihres Mantels 14 oval ausgebildet. Sie sitzt auf einem an der Prüftrommel 1 angeordneten Träger 12, der eine Bohrung 13 zum Zu- oder Ableiten von Prüfluft aufweist. Die Prüfluft wird von der Prüftrommel abgegeben oder strömt zu ihr hin. Zur Steuerung der Prüfluft dienen bekannte nicht dargestellte Steuerschlitze in der Prüftrommel 1. Der im wesentlichen zylindrische Träger 12, der unterschiedliche Durchmesser hat, weist in einem ersten Bereich 15, dem Positionierungsbereich, eine nutartige Ausnehmung 16 auf, in die ein nach innen gerichteter Steg 17 der Dichtung 6 eingreift. Damit wird eine formschlüssige Verbindung zwischen Dichtung und Trommel gebildet, durch die eine Dichtung sich stets in der richtigen Lage zur Prüftrommel oder den darauf geförderten Zigaretten befindet. Dem Positionierungsbereich 15 in Richtung auf die Prüftrommel 1 benachbart befindet sich ein zweiter Bereich 18, in dem der Träger 12 einen geringeren Durchmesser aufweist als im Positionierungsbereich 15. So kann der aus gummielastischem Material bestehende Mantel 14 der Dichtung 6 einfach über den Positionierungsbereich 15 in den Klemmbereich 18 gezogen werden, wo er infolge seiner Elastizität "einschnappt" und so festgehalten wird.Figure 2 shows an oval sealing end 8 at a short distance from the likewise oval receptacle 7 of a seal 6. The receptacle 7 of the seal 6 leaves the Recognize opening 11 for the test air. The seal 6 is preferably also in the area her coat 14 oval. It sits on an arranged on the test drum 1 Carrier 12, which has a bore 13 for supplying or discharging test air. The test air is emitted from the test drum or flows towards it. to Control of the test air serve known control slots, not shown, in the Test drum 1. The essentially cylindrical support 12, the different Has diameter, has in a first area 15, the positioning area, a groove-like recess 16 into which an inward web 17 of the Seal 6 engages. This creates a positive connection between the seal and drum formed, through which a seal is always in the correct position Test drum or the cigarettes conveyed on it. The positioning area 15 in the direction of the test drum 1 is adjacent second area 18, in which the carrier 12 has a smaller diameter than in the positioning area 15. Thus, the one consisting of rubber-elastic material Jacket 14 of the seal 6 simply over the positioning area 15 in the clamping area 18 are drawn where it due to its elasticity "snaps" and is held so.

Bei der in Figur 3 gezeigten Lage einer Zigarette 3 in Dichtstellung (Prüfstellung) umfassen die Dichtlippen 19 der Dichtung 6 infolge des von dem Zigarettenende 8 auf die Bodenfläche 21 der Aufnahme 7 ausgeübten Drucks das Ende 8 der Zigarette 3 dichtend, so daß das Innere der Zigarette 3 praktisch vollständig von der Umgebungsluft abgeschlossen ist.In the position of a cigarette 3 shown in FIG. 3 in the sealing position (test position) include the sealing lips 19 of the seal 6 as a result of the cigarette end 8 pressure exerted on the bottom surface 21 of the receptacle 7 the end 8 of the cigarette 3 sealing, so that the inside of the cigarette 3 practically completely from the Ambient air is closed.
