Abstract

In the checking of cigarettes (10, 11) of cigarette groups (16, 17) in pockets (13, 14) of a conveyor, in particular of a cigarette revolver (12), difficulties arise in respect of the adequate spacing of checking elements (29..32) from one another when the cigarettes (10, 11) have a particularly small diameter. In order nevertheless to permit undisturbed checking by moving the checking elements (29..32) up to the front ends of the cigarettes (10, 11), the latter are checked successively in several, in particular two, steps, the checking elements (29..32) checking during each of these checking cycles cigarettes which are at a relatively large distance from one another. In particular, only every second cigarette within rows (18..21) of the cigarettes is checked. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Prüfen von Zigaretten einer insbesondere dem Inhalt einer Zigaretten-Packung entsprechenden Zigaretten-Gruppe, wobei jeder Zigarette der Zigaretten-Gruppe zugeordnete Prüforgane an Stirnflächen der Zigaretten heranbewegt werden. Weiterhin betrifft die Erfindung eine Vorrichtung zum Prüfen der Zigaretten.The invention relates to a method for testing cigarettes of a cigarette group, in particular corresponding to the content of a cigarette pack, wherein test organs assigned to each cigarette of the cigarette group are moved towards the end faces of the cigarettes. The invention further relates to a device for checking the cigarettes.

Die Prüfung der Zigaretten erfolgt im Zusammenhang mit der Verpackung derselben. Die Zigaretten werden in bezug auf korrekte, ausreichende Tabakfüllung überprüft und hinsichtlich des Vorhandenseins bzw. der korrekten Ausbildung eines Filters, sofern es sich dabei um Filterzigaretten handelt.The cigarettes are checked in connection with their packaging. The cigarettes are checked for correct, sufficient tobacco filling and for the presence or the correct design of a filter, if the filter cigarettes are concerned.

Zu diesem Zweck werden Prüforgane eines Prüfaggregats an die Stirnflächen der Zigaretten herangefahren. Die Prüforgane können unterschiedlich ausgebildet sein. Vielfach werden axialbewegbare, federbelastete Prüfstößel verwendet, etwa in der Ausführung gemäß DE-PS 22 29 382. Bekannt und geeignet sind aber auch opto-elektro­nisch arbeitende Sensoren. Mehrere derartiger Prüforgane sind an einer Halterung zu einem Prüfaggregat zusammenge­faßt. Bei Feststellung fehlerhafter Zigaretten wird üblicherweise die gesamte Zigaretten-Gruppe aus dem Verpackungsprozeß ausgesondert.For this purpose, test organs of a test unit are brought up to the end faces of the cigarettes. The test organs can be designed differently. Axially movable, spring-loaded test plungers are often used, for example in the version according to DE-PS 22 29 382. However, optoelectronic sensors are also known and suitable. Several such test organs are combined on a holder to form a test unit. If defective cigarettes are found, the entire cigarette group is usually removed from the packaging process.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs genannte Verfahren zum Prüfen von Zigaretten dahingehend weiterzuentwickeln, daß bei hoher Leistung, also bei kurzen Arbeits- bzw. Fördertakten, eine große Genauigkeit der Prüfung der Zigaretten erzielt wird, insbesondere auch bei in Dichtlage angeordneten Zigaretten kleinen Durchmessers.The invention has for its object to develop the above-mentioned method for testing cigarettes in such a way that a high accuracy of the testing of the cigarettes is achieved at high power, that is to say with short work or delivery cycles, in particular also in the case of small cigarettes arranged in the sealing position Diameter.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Ver­fahren dadurch gekennzeichnet, daß die Zigaretten einer Zigaretten-Gruppe in mehreren, insbesondere zwei aufein­anderfolgenden Prüftakten geprüft werden, wobei jeweils räumlich im Abstand voneinanderliegender Zigaretten gleichzeitig während eines Prüftaktes geprüft werden.To achieve this object, the method according to the invention is characterized in that the cigarettes of a cigarette group are tested in several, in particular two, successive test cycles, with cigarettes spaced apart from one another being tested simultaneously during a test cycle.

Bei dem erfindungsgemäßen Verfahren wird demnach nicht die komplette Zigaretten-Gruppe durch eine der Anzahl der Zigaretten entsprechende Anzahl von Prüforganen gleichzeitig geprüft, sondern es wird jeweils nur eine Teilzahl der Zigaretten einer Zigaretten-Gruppe geprüft. Die gesamte Zigaretten-Gruppe wird dann in mehreren, einander ergänzenden Prüftakten geprüft.In the method according to the invention, the entire cigarette group is therefore not checked simultaneously by a number of test organs corresponding to the number of cigarettes, but only a partial number of cigarettes in a cigarette group is checked in each case. The entire cigarette group is then checked in several, complementary test cycles.

Die Auswahl der je Prüftakt zu erfassenden Zigaretten erfolgt nach Maßgabe einer räumlich optimalen Anordnung der Prüforgane eines Prüfaggregats. Diese können dadurch so ausgebildet und insbesondere in einem solchen Abstand voneinander angeordnet sein, daß eine wechselseitige Störung oder Beeinflussung während des Prüftaktes nicht erfolgen kann.The cigarettes to be recorded per test cycle are selected in accordance with an optimal spatial arrangement the test organs of a test unit. As a result, these can be designed and in particular arranged at such a distance from one another that mutual interference or influencing cannot take place during the test cycle.

Bei Anordnung der Zigaretten einer Zigaretten-Gruppe in Reihen (Längsreihen und gegebenenfalls Querreihen) sind die Prüforgane so angeordnet, daß bei jedem Prüftakt nur jede zweite Zigarette geprüft wird. Beim nächsten Prüftakt werden dann die zuvor ausgelassenen Zigaretten geprüft.When the cigarettes of a cigarette group are arranged in rows (longitudinal rows and possibly transverse rows), the test organs are arranged in such a way that only every second cigarette is checked with each test cycle. At the next test cycle, the previously omitted cigarettes are then checked.

Die Vorrichtung zum Prüfen der Zigarette ist entsprechend eingerichtet, nämlich mit Prüforganen, deren Abstand voneinander dem Abstand von zwei Zigaretten entspricht. Bei Prüfung in zwei Prüftakten weist jedes Prüfaggregat die Hälfte der insgesamt erforderlichen Prüforgane auf. Diese sind in Reihen angeordnet, derart, daß jede zweite Zigarette durch ein Prüforgan beaufschlagt wird.The device for testing the cigarette is set up accordingly, namely with test organs whose distance from one another corresponds to the distance from two cigarettes. When testing in two test cycles, each test unit has half of the total required test organs. These are arranged in rows in such a way that every second cigarette is acted upon by a test organ.

Nach einem weiteren Merkmal der Erfindung sind zur Prüfung der beiden Enden der Zigaretten mehrere, insbe­sondere zwei Prüfaggregate zu beiden Seiten der Zi­garetten-Gruppen bzw. der Bewegungsbahn derselben angeordnet. Die Prüfaggregate werden während einer Stillstandsphase der taktweise geförderten Zigaretten-­Gruppen diesen zugestellt. Während eines Prüftaktes werden demnach Teilgruppen von zwei Zigaretten-Gruppen gleichzeitig geprüft, so daß nach jedem Fördertakt eine Zigaretten-Gruppe komplett geprüft ist.According to a further feature of the invention, for testing the two ends of the cigarettes, several, in particular two, test units are arranged on both sides of the cigarette groups or the movement path thereof. The test units are delivered to the cigarette groups which are conveyed in cycles during a standstill phase. Sub-groups of two cigarette groups are therefore tested simultaneously during a test cycle, so that a cigarette group is completely tested after each funding cycle.

Weitere Merkmale der Erfindung betreffen die Ausbildung der Prüfaggregate, deren Lagerung und Betätigung.Further features of the invention relate to the design of the test units, their storage and operation.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigt:

  • Fig. 2 eine Vorderansicht des Zigaretten-Revolvers gemäß Fig. 1,
  • Fig. 3 eine Einzelheit des Zigaretten-Revolvers in einer Darstellung entsprechend Fig. 1 bei vergrößertem Maßstab,
  • Fig. 4 eine teilweise eingehüllte Zigaretten-Gruppe in perspektivischer Darstellung.
An embodiment of the invention is explained below with reference to the drawings. It shows:
  • 1 shows a conveyor for cigarette groups, namely a cigarette revolver, in a schematic side view,
  • 2 shows a front view of the cigarette revolver according to FIG. 1,
  • 3 shows a detail of the cigarette revolver in a representation corresponding to FIG. 1 on an enlarged scale,
  • Fig. 4 is a partially wrapped cigarette group in perspective.

Die Prüfung von Zigaretten 10, 11 findet im Zusammenhang mit der Verpackung derselben statt. Die als Ausführungs­beispiel gezeigte Vorrichtung besteht aus einem Zi­garetten-Revolver 12, der üblicherweise im Anschluß eines Zigaretten-Magazins einer Verpackungsmaschine in vertikaler Ebene taktweise drehbar ist. Der Zigaretten-­Revolver 12 ist längs seines Umfangs mit einer Mehrzahl von Taschen 13, 14 versehen. Diese sind an den axialen Stirnseiten offen. Eine radial außenliegende Taschen­wand 14 ist mit einem in Längsrichtung weisenden Schlitz 15 für den Durchtritt eines Förderorgans versehen.The testing of cigarettes 10, 11 takes place in connection with the packaging of the same. The device shown as an exemplary embodiment consists of a cigarette turret 12 which can usually be rotated in cycles in the vertical plane in the connection of a cigarette magazine of a packaging machine. The cigarette revolver 12 is provided with a plurality of pockets 13, 14 along its circumference. These are open on the axial faces. A radially outer pocket wall 14 is provided with a slot 15 pointing in the longitudinal direction for the passage of a conveying member.

Die Zigaretten 10, 11 werden in bekannter Weise durch Schieber dem Zigaretten-Magazin (nicht dargestellt) entnommen und in Längsrichtung unter Bildung jeweils einer Zigaretten-Gruppe 16, 17 dem Zigaretten-Revolver 12, nämlich einer sich im oberen Bereich befindenden Tasche 13 oder 14 zugeführt. Bei dem vorliegenden Beispiel werden zweckmäßigerweise die beiden oberen schräggerichteten Taschen 13, 14 gleichzeitig mit je einer Zigaretten-Gruppe 16, 17 befüllt. Danach wird der Zigaretten-Revolver 12 um eine einer Tasche 13, 14 entsprechende Teilung weitergeschaltet.The cigarettes 10, 11 are removed in a known manner from the cigarette magazine (not shown) by means of a slide and in the longitudinal direction, each forming a cigarette group 16, 17 from the cigarette revolver 12, namely a pocket 13 or 14 located in the upper region fed. In the present example, the two upper oblique pockets 13, 14 are expediently filled with one cigarette group 16, 17 at a time. Then the cigarette revolver 12 is advanced by a division corresponding to a pocket 13, 14.

Die Zigaretten-Gruppen 16, 17 bestehen üblicherweise aus mehreren Reihen 18, 19, 20, 21. Innerhalb dieser Reihen 18..21 liegen die Zigaretten in Dichtlage. Die Anordnung kann so getroffen sein, daß die Zigaretten benachbarter Reihen versetzt zueinander liegen (Sattel­lage). Bei dem vorliegenden Ausführungsbeispiel besteht aber jede Zigaretten-Gruppe 16, 17 aus einer verhältnis­mäßig großen Anzahl von vierzig Zigaretten 10, 11. Jede Reihe 18..21 besteht demnach aus zehn Zigaretten 10, 11. Die Anordnung ist so getroffen, daß Querreihen 22 aus jeweils vier Zigaretten gebildet sind.The cigarette groups 16, 17 usually consist of a number of rows 18, 19, 20, 21. Within these rows 18, 21, the cigarettes are in a sealed position. The arrangement can be such that the cigarettes of adjacent rows are offset from one another (saddle position). In the present exemplary embodiment, however, each cigarette group 16, 17 consists of a relatively large number of forty cigarettes 10, 11. Each row 18..21 accordingly consists of ten cigarettes 10, 11. The arrangement is such that transverse rows 22 consist of four cigarettes are formed.

Die so ausgebildeten Zigaretten-Gruppen 16, 17 gelangen durch Drehung des Zigaretten-Revolvers 12 zunächst in eine erste Prüfstation 23 und danach in eine zweite Prüfstation 24. Jede Prüfstation ist mit wenigstens einem Prüfaggregat 25, 26 ausgerüstet. Bei dem vorliegen­den Ausführungsbeispiel werden beide freien Enden der Zigaretten 10, 11 geprüft, so daß weitere Prüfaggregate 27, 28 auf der gegenüberliegenden Seite des Zigaretten-­Revolvers 12 angeordnet sind.By rotating the cigarette turret 12, the cigarette groups 16, 17 thus formed first reach a first test station 23 and then a second test station 24. Each test station is equipped with at least one test unit 25, 26. In the present exemplary embodiment, both free ends of the cigarettes 10, 11 are tested, so that further test units 27, 28 are arranged on the opposite side of the cigarette revolver 12.

Jedes Prüfaggregat 25..28 hat die Aufgabe, während eines Prüftakts eine bestimmte Anzahl von Zigaretten 10,11 hinsichtlich korrekter Ausbildung zu überprüfen. Zu diesem Zweck sind die Prüfaggregate 25..28 mit Prüforganen 29, 30, 31, 32 ausgerüstet. Bei dem vorlie­genden Ausführungsbeispiel sind diese Prüforgane 29..­32 als verhältnismäßig dünne, axial bewegbare Stößel ausgebildet. Diese sind federbelastet. Zur Durchführung einer Prüfung der Zigaretten 10, 11 werden die Prüfaggre­gate 25..28 an die betreffende Zigaretten-Gruppe 16,17 heranbewegt, derart, daß die Endflächen der Zigaretten 10, 11 durch die Prüforgane 29..32 beaufschlagt werden. Es wird ein gewisser Druck ausgeübt, derart, daß bei ordnungsgemäß ausgebildeten Zigaretten die federbelaste­ten Prüforgane (Stößel) in das Prüfaggregat 25..28 verschoben werden. Bei fehlerhaften Zigaretten findet keine oder nur eine geringere Axialverschiebung des betreffenden Prüforgans statt. Hierdurch wird in geeig­neter Weise ein Fehlersignal ausgelöst.Each test unit 25 to 28 has the task of checking a certain number of cigarettes 10, 11 for correct training during a test cycle. For this purpose, the test units 25..28 are equipped with test organs 29, 30, 31, 32. In the present exemplary embodiment, these test organs 29, 32 are designed as relatively thin, axially movable plungers. These are spring loaded. To carry out a test of the cigarettes 10, 11, the test units 25, 28 are moved towards the relevant cigarette group 16, 17 in such a way that the end faces of the cigarettes 10, 11 are acted upon by the test members 29, 32. A certain amount of pressure is exerted in such a way that, in the case of properly designed cigarettes, the spring-loaded test organs (plunger) are inserted into the test unit 25..28 be moved. In the case of defective cigarettes, there is no or only a slight axial displacement of the test device in question. In this way, an error signal is triggered in a suitable manner.

Die Anzahl der Prüforgane 29..32 je Prüfaggregat 25..28 ist geringer als die Gesamtzahl der Zigaretten 10,11 je Zigaretten-Gruppe 16, 17. Bei dem gezeigten Ausführungs­beispiel mit jeweils zwei auf einer Seite der Zigaretten-­Gruppen 16, 17 angeordneten Prüfaggregaten 25,26 bzw. 27,28 wird die gesamte Zigaretten-Gruppe 16, 17 in zwei Takten geprüft. In der ersten Prüfstation 23 werden die in Fig. 3 entsprechend markierten Zigaretten 10 geprüft. Die Anordnung der Prüforgane 29 des Prüfaggregats 25 ist so gewählt, daß jede zweite Zigarette 10 innerhalb der Reihen 18..21 geprüft wird. Die Prüforgane 29 einer benachbarten Reihe sind versetzt angeordnet. Dadurch ist es möglich, die bei diesem Ausführungsbeispiel der halben Anzahl der Zigaretten 10, 11 einer Zigaretten-­Gruppe 16, 17 entsprechende Anzahl an Prüforganen 29..32 so zu verteilen, daß diese einen maximalen Abstand voneinander haben. Bei der Prüfung derselben Zigaretten-Gruppe in der Prüfstation 24 - nach einem Fördertakt des Zigaretten-Revolvers 12 - werden durch entsprechende versetzte Anordnung der Prüforgane 31 die in der vorhergehenden Prüfstation 23 ausgelassenen Zigaretten 11 geprüft. Auch hier wiederum haben die Prüforgane 31 denselben maximalen Abstand voneinander. In beiden Fällen sind die Prüforgane 29, 31 in regel­mäßiger Formation verteilt.The number of test organs 29..32 per test unit 25..28 is less than the total number of cigarettes 10.11 per cigarette group 16, 17. In the exemplary embodiment shown, two are arranged on one side of the cigarette groups 16, 17 The entire cigarette group 16, 17 is tested in two cycles, test units 25, 26 and 27, 28. The cigarettes 10 correspondingly marked in FIG. 3 are tested in the first test station 23. The arrangement of the test organs 29 of the test unit 25 is selected so that every second cigarette 10 is checked within the rows 18-21. The test organs 29 of an adjacent row are arranged offset. This makes it possible to distribute the number of test organs 29, 32 corresponding to half the number of cigarettes 10, 11 of a cigarette group 16, 17 in this embodiment such that they are at a maximum distance from one another. When testing the same cigarette group in the test station 24 - after a conveying cycle of the cigarette revolver 12 - the cigarettes 11 left out in the previous test station 23 are tested by a correspondingly offset arrangement of the test members 31. Again, the test organs 31 have the same maximum distance from one another. In both cases, the test organs 29, 31 are distributed in regular formation.

Die zu den Prüfaggregaten 25, 26 gegenüberliegenden Prüfaggregate 27 und 28 sind in gleicher Weise ausge­bildet und mit Prüforganen 30, 32 bestückt. Die Prüf­organe 30 des Prüfaggregats 27 sind axial gleichgerichtet mit den Prüforganen 29 auf der gegenüberliegenden Seite. Infolge gleichzeitiger Zustellung aller Prüf­ aggregate 25..28 wirken jeweils die Prüforgane auf dieselben Zigaretten 10, 11.The test units 27 and 28 opposite the test units 25, 26 are designed in the same way and are equipped with test members 30, 32. The test organs 30 of the test unit 27 are axially aligned with the test organs 29 on the opposite side. As a result of the simultaneous delivery of all tests Aggregates 25..28 each have the test organs acting on the same cigarettes 10, 11.

Die bei dem gezeigten Ausführungsbeispiel eingesetzten vier Prüfaggregate 25..28 werden gemeinsam und gleich­zeitig betätigt. Zu diesem Zweck sind die auf jeweils einer Seite des Zigaretten-Revolvers 12 angeordneten Prüfaggregate 25 und 26 einerseits sowie 27 und 28 andererseits miteinander verbunden, im vorliegenden Fall durch eine Traverse 33, 34. An diesen sind jeweils hin- und herbewegbare Betätigungsstangen 35, 36 ange­bracht. Der Antrieb derselben erfolgt von einer Seite des Zigaretten-Revolvers 12. Zu diesem Zweck ist die sich auf der gegenüberliegenden Seite des Zigaretten-­Revolvers 12 befindliche Traverse 33 mit einer Betäti­gungsstange 36 verbunden, die seitlich an dem Zigaretten-­Revolver 12 vorbeigeführt wird. Diese Betätigungsstange 36 ist durch eine Führungsöffnung 37 in der Traverse 34 hindurchgeführt. Die Führungsöffnung 34 bildet eine Gleitführung für die Betätigungsstange 36. Die andere Betätigungsstange 35 ist mit einer Führungsstange 38 bis in den Bereich der gegenüberliegenden Traverse 33 verlängert und hier ebenfalls in einer Führungsöffnung 39 geführt. Durch diese wechselseitige Abstützung und Lagerung der Betätigungsstangen 35, 36 in bzw. an den Traversen 33 und 34 wird zugleich eine verkantungsfreie Bewegung der Prüfaggregate 25..28 gewährleistet.The four test units 25 to 28 used in the exemplary embodiment shown are actuated together and simultaneously. For this purpose, the test units 25 and 26 on the one hand and 27 and 28 on the other hand, which are arranged on each side of the cigarette revolver 12, are connected to one another, in the present case by a crossmember 33, 34. Actuating rods 35, 36 can be moved back and forth on these appropriate. They are driven from one side of the cigarette turret 12. For this purpose, the cross member 33 located on the opposite side of the cigarette turret 12 is connected to an actuating rod 36 which is guided past the cigarette turret 12 at the side. This actuating rod 36 is passed through a guide opening 37 in the cross member 34. The guide opening 34 forms a sliding guide for the actuating rod 36. The other actuating rod 35 is extended with a guide rod 38 into the area of the opposite cross member 33 and is likewise guided here in a guide opening 39. This mutual support and mounting of the actuating rods 35, 36 in or on the crossbeams 33 and 34 also ensures that the test units 25 to 28 do not tilt.

Die Zigaretten 10, 11 ragen mit ihren Enden geringfügig aus den Taschen 13, 14 heraus. Mit geringem Abstand von den Enden der Zigaretten 10, 11 ist zu beiden Seiten des Zigaretten-Revolvers 12 jeweils eine ortsfeste Begrenzungsscheibe 40, 41 angeordnet. Im Bereich der Prüfstationen 23, 24 sind die Begrenzungsscheiben 40, 41 mit Bohrungen 42 versehen, die in Größe und räumlicher Anordnung auf die Prüforgane 29..32 abgestimmt sind, so daß diese zur Durchführung der Prüfung der Zigaretten durch die Bohrungen 42 hindurchtreten können. Während eines Drehtaktes des Zigaretten-Revolvers 12 sind die Prüfaggregate 25..28 mit den Prüforganen 29..32 bis zur Außenseite der Begrenzungsscheiben 40, 41 zurückgezogen.The ends of the cigarettes 10, 11 protrude slightly from the pockets 13, 14. At a short distance from the ends of the cigarettes 10, 11, a stationary limiting disk 40, 41 is arranged on each side of the cigarette revolver 12. In the area of the test stations 23, 24, the limiting disks 40, 41 are provided with bores 42, the size and spatial arrangement of which are matched to the test organs 29, 32 so that they can be used to test the cigarettes can pass through the bores 42. During a rotation cycle of the cigarette revolver 12, the test units 25, 28 with the test organs 29, 32 are withdrawn to the outside of the limiting disks 40, 41.

Die geprüften Zigaretten-Gruppen 16, 17 werden durch den Zigaretten-Revolver 12 einer sich unten erstrecken­den horizontalen Abförderbahn 43 zugeführt. Diese ist in bekannter Weise mit einem umlaufenden Förderer (nicht gezeigt) versehen, dessen Mitnehmer in Längs­richtung durch die Taschen 13, 14 hindurchgefördert werden unter Mitnahme der Zigaretten-Gruppen 16, 17.The tested cigarette groups 16, 17 are fed through the cigarette turret 12 to a horizontal discharge conveyor 43 which extends below. This is provided in a known manner with a rotating conveyor (not shown), the drivers of which are conveyed in the longitudinal direction through the pockets 13, 14, taking the cigarette groups 16, 17 with them.

Die beschriebene Prüfvorrichtung ist besonders geeignet für die Prüfung von Zigaretten mit extrem kleinem Durchmesser von z.B. 5,7 mm. In Fig. 4 ist eine aus solchen Zigaretten 10, 11 bestehende Zigaretten-Gruppe 16, 17 gezeigt, mit einer Innenumhüllung 44 aus Stanniol oder dergleichen. Eine aus diesen dünnen Zigaretten 10,11 bestehende Zigaretten-Packung enthält hier vierzig Zigaretten, die in der beschriebenen Weise in Reihen 18..21 angeordnet sind. Trotz des geringen Durchmessers der Zigaretten können die Prüforgane 29..32 in angemesse­ner Weise ausgebildet sein und ohne wechselseitige Beeinträchtigung arbeiten. Durch die beschriebene Anordnung der Prüforgane 29..32 ist ein ausreichender Abstand derselben voneinander möglich.The test device described is particularly suitable for testing cigarettes with an extremely small diameter, e.g. 5.7 mm. 4 shows a cigarette group 16, 17 consisting of such cigarettes 10, 11, with an inner wrapping 44 made of tin foil or the like. A cigarette packet consisting of these thin cigarettes 10, 11 here contains forty cigarettes which are arranged in rows 18, 21 in the manner described. Despite the small diameter of the cigarettes, the test organs 29.32 can be designed in an appropriate manner and can work without mutual interference. Due to the described arrangement of the test organs 29.32, a sufficient distance between them is possible.
