Description

Die Erfindung betrifft ein Verfahren zum Feststellen und Aus­sondern von fehlerhaften Zigaretten (Fehlzigaretten) im Be­reich eines Zigaretten-Magazins, dessen unterer Bereich aus (Gruppen von) Magazin-Schächten zur Bildung von Zigaretten-­Gruppen und zum Ausschub derselben besteht, wobei die Zigaret­ten oberhalb der Magazin-Schächte in aufrechten Reihen eine Prüfzone (Prüfschächte) durchlaufen, in dieser einzeln ge­prüft und Fehlzigaretten ausgesondert werden. Weiterhin be­trifft die Erfindung eine Vorrichtung zum Feststellen und Aussondern von Fehlzigaretten.The invention relates to a method for detecting and rejecting defective cigarettes (defective cigarettes) in the area of a cigarette magazine, the lower area of which consists of (groups of) magazine chutes for the formation of cigarette groups and for the ejection thereof, the cigarettes above the Magazine shafts pass through an inspection zone (inspection shafts) in upright rows, in which they are individually checked and faulty cigarettes are sorted out. The invention further relates to a device for detecting and rejecting faulty cigarettes.

Es ist erforderlich und üblich, Zigaretten vor ihrer Ver­packung auf ordnungsgemäße Ausbildung zu überprüfen. Diese Zigarettenprüfung findet vorwiegend nach Bildung der Ziga­retten-Gruppen, z. B. im Bereich eines Zigaretten-Revolvers statt. Grundsätzlich ist es aber auch bereits bekannt, Zi­garetten im Bereich des Zigaretten-Magazins zu überprüfen und etwaige Fehlzigaretten hier auszusondern. Die Erfin­dung befaßt sich mit der Zigarettenprüfung und Aussonderung von Fehlzigaretten im Bereich des Zigaretten-Magazins.It is necessary and customary to check cigarettes for proper training before packaging them. These Cigarette testing takes place mainly after formation of the cigarette groups, e.g. B. in the area of a cigarette revolver instead. In principle, however, it is also already known to check cigarettes in the area of the cigarette magazine and to sort out any missing cigarettes here. The invention is concerned with the testing of cigarettes and the selection of faulty cigarettes in the area of the cigarette magazine.

Aufgabe der Erfindung ist es, die Zigarettenprüfung mit höherer Leistungsfähigkeit durchzuführen und zugleich aber eine schonende Behandlung der empfindlichen Zigaretten sicherzustellen.The object of the invention is to carry out the cigarette test with higher performance and at the same time to ensure gentle treatment of the sensitive cigarettes.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Ver­fahren dadurch gekennzeichnet, daß eine der Anzahl der gleichzeitig geprüften Zigaretten entsprechende Anzahl von Zigaretten in jedem Prüfschacht von den nachfolgenden Zigaretten abgesondert werden, insbesondere durch Querver­schiebung und daß diese Zigaretten - gegebenenfalls nach vorherigem Ausstoß von Fehlzigaretten - sodann nach unten freigelassen werden.To achieve this object, the method according to the invention is characterized in that a number of cigarettes corresponding to the number of cigarettes tested at the same time is separated from the subsequent cigarettes in each inspection shaft, in particular by transverse displacement, and that these cigarettes then - if necessary after previous ejection of faulty cigarettes be released below.

Die Zigaretten werden demnach innerhalb des Zigaretten-­Magazins in eine aus aufrechten Prüfschächten bestehende Prüfeinheit geleitet und hier in bezug auf ordnungsgemäße Ausbildung überprüft. Die geprüften Zigaretten werden so­dann - nach Ausstoß etwaiger Fehlzigaretten - nach unten freigegeben. Sie fallen unter Eigengewicht auf einen Vor­rat an geprüften Zigaretten oberhalb der Magazinschächte. Die aufrechten Reihen der Zigaretten in den Prüfschächten wird währenddessen angehalten. Die Prüfung wird während der Abgabe der bereits geprüften Zigaretten durchgeführt.Accordingly, the cigarettes are passed within the cigarette magazine into a test unit consisting of upright test shafts and are checked here for proper training. The tested cigarettes are then released downwards after any faulty cigarettes have been ejected. They fall under their own weight on a stock of tested cigarettes above the magazine shafts. The upright rows of cigarettes in the test shafts are stopped in the meantime. The test is carried out during the delivery of the cigarettes that have already been tested.

Die erfindungsgemäße Vorrichtung ist mit einer Prüfeinheit im Zigaretten-Magazin mit Abstand oberhalb der Magazin-­Schächte versehen. Diese besteht aus im wesentlichen auf­rechten Prüfschächten und diesen zugeordneten Zigaretten-­ Prüforganen. Am unteren (Austritts-)Ende der Prüfeinheit ist ein für alle Prüfschächte wirksames Zigaretten-Über­gabeorgan angeordnet. Dieses ist durch Querverschiebung in unterschiedliche Relativstellungen gegenüber den Prüf­schächten bewegbar. Dadurch wird die Übergabe der geprüften Zigaretten an den unteren Teil des Zigaretten-Magazins ermöglicht, während gleichzeitig darüberliegende Zigaret­ten im Bereich der Prüfschächte während des Stillstands geprüft werden.The device according to the invention is provided with a test unit in the cigarette magazine at a distance above the magazine chutes. This consists of essentially upright test wells and associated cigarette Inspection bodies. At the lower (exit) end of the test unit there is a cigarette transfer device that is effective for all test shafts. This can be moved to different relative positions with respect to the test wells by transverse displacement. This enables the checked cigarettes to be transferred to the lower part of the cigarette magazine, while at the same time cigarettes lying over them are checked in the area of the test shafts during standstill.

Weitere Merkmale der Erfindung beziehen sich auf die ge­stalterische Ausbildung des Zigaretten-Magazins sowie auf Einzelheiten der Prüfeinheit innerhalb desselben.Further features of the invention relate to the design of the cigarette magazine and to details of the test unit within the same.

Vor der Bildung von Zigaretten-Gruppen 10 aus einer dem Inhalt einer Zigaretten-Packung entsprechenden Anzahl von Zigaretten 11 werden diese in ein Zigaretten-Magazin 12 eingefüllt. Dieses ist im unteren Bereich mit aufrechten Magazin-Schächten, je zur Aufnahme einer aufrechten Ziga­retten-Reihe 14 versehen. Jeweils mehrere, dem Inhalt einer Zigaretten-Packung entsprechende Magazin-Schächte 13 sind zu Schacht-Gruppen 15 zusammengefaßt. Am unteren Ende wer­den die Zigaretten-Gruppen 10 in üblicher Weise durch ge­eignete Ausstoßorgane 16 aus den Magazin-Schächten 13 aus­gestoßen und der Verpackung zugeführt.Before the formation of cigarette groups 10 from a number of cigarettes 11 corresponding to the content of a cigarette packet, these are filled into a cigarette magazine 12. This is provided in the lower area with upright magazine chutes, each for receiving an upright row of cigarettes 14. Several magazine chutes 13 corresponding to the contents of a cigarette packet are combined into chute groups 15. At the lower end, the cigarette groups 10 are ejected from the magazine shafts 13 in a conventional manner by means of suitable ejection elements 16 and fed to the packaging.

Das Zigaretten-Magazin 12 ist im vorliegenden Falle in be­sonderer Weise gestaltet und innen etwa auf halber Höhe, jedenfalls mit Abstand oberhalb der Schacht-Gruppen 15 mit einer Prüfeinheit 17 versehen. Diese nimmt die von oben nach unten innerhalb des Zigaretten-Magazins 12 unter Eigen­gewicht fließenden Zigaretten 11 zeitweilig auf und über­prüft sie in bezug auf korrekte Ausbildung (Vorhandensein von Tabak, Filter etc.). Etwaige fehlerhafte Zigaretten (Fehlzigaretten 18) werden im Bereich der Prüfeinheit 17 identifiziert und hier ausgesondert, so daß den Magazin-­Schächten 13 ausschließlich geprüfte, also korrekte Ziga­retten zugeführt werden.In the present case, the cigarette magazine 12 is designed in a special way and is provided with a test unit 17 on the inside approximately halfway up, at least at a distance above the shaft groups 15. This temporarily picks up the cigarettes 11 flowing under their own weight from top to bottom within the cigarette magazine 12 and checks them for correct formation (tobacco, filter, etc.). Any defective cigarettes (defective cigarettes 18) are identified in the area of the test unit 17 and sorted out here, so that only checked, ie correct, cigarettes are fed to the magazine chutes 13.

Für die Durchführung der Prüfung werden die Zigaretten 11 im Bereich der Prüfeinheit 17 jeweils zeitweilig angehal­ten, so daß die Prüfung während einer Ruhephase der Zi­garetten erfolgt. Die Fehlzigaretten 18 werden im Bereich einer Abgabeebene ausgesondert, nämlich durch Ausschieben in Axialrichtung. Die intakten Zigaretten werden nach un­ten freigegeben und fallen unter Eigengewicht auf einen oberhalb der Magazin-Schächte 13 gebildeten Zigaretten­vorrat 20. Dieser wird hinsichtlich seines Pegelstandes überprüft, z. B. durch Lichtschranken 21 und 22, jeweils zuständig für den unteren, minimalen und den oberen, maximalen Zigarettenpegel.To carry out the test, the cigarettes 11 are temporarily stopped in the area of the test unit 17, so that the test takes place during a resting phase of the cigarettes. The missing cigarettes 18 are discarded in the area of a delivery level, namely by being pushed out in the axial direction. The intact cigarettes are released downwards and fall under their own weight onto a cigarette stock 20 formed above the magazine chutes 13. This is checked for its level, e.g. B. by light barriers 21 and 22, each responsible for the lower, minimum and upper, maximum cigarette levels.

Die Zigaretten 11 werden über eine obere Einfüllöffnung 23 in das Zigaretten-Magazin 12 eingeführt. Dieses be­steht aus einem im vorliegenden Falle annähernd tropfen­förmigen Gehäuse 24. Im Bereich der größten Querabmessung des Gehäuses ist die Prüfeinheit 17 angeordnet. An der Innenseite des Gehäuses 24 befinden sich Leitbleche 25, die zu der sich über die volle Breite des Zigaretten-­Magazins 12 erstreckenden Prüfeinheit 17 führen.The cigarettes 11 are introduced into the cigarette magazine 12 via an upper filling opening 23. This consists of an approximately drop-shaped housing 24 in the present case. The test unit 17 is arranged in the region of the largest transverse dimension of the housing. On the inside of the housing 24 there are baffles 25 which lead to the test unit 17 which extends over the full width of the cigarette magazine 12.

Die durch die Prüfeinheit 17 hindurchfließenden, achs­parallel ausgerichteten Zigaretten 11 werden in einzelne, aufrechte Prüfreihen 26 aufgegliedert. Die Anzahl dersel­ben entspricht etwa der Anzahl der Magazin-Schächte 13. Zu diesem Zweck sind innerhalb eines Blocks 27 aufrechte Prüfschächte 28 parallel und mit gleichen Abständen von­einander angeordnet. An den oberen Eintrittsenden der Prüfschächte 28 sind bewegbare, insbesondere drehbare Leitstäbe 29 angebracht, die ein sicheres, schonendes Einführen der Zigaretten in die Prüfschächte 28 gewähr­leisten.The axially parallel cigarettes 11 flowing through the test unit 17 are broken down into individual, upright test rows 26. The number of these corresponds approximately to the number of magazine shafts 13. For this purpose, upright test shafts 28 are arranged parallel and at equal distances from one another within a block 27. Movable, in particular rotatable, guide rods 29 are attached to the upper inlet ends of the test wells 28, which ensure safe, gentle insertion of the cigarettes into the test wells 28.

Innerhalb der Prüfschächte 28 werden die Prüfreihen 26 an Prüforganen 30 vorbeibewegt, die seitlich am Gehäuse 24 angebracht sind, nämlich in Seitenwänden 31 und 32 des Gehäuses 24, so daß die Prüforgane 30 auf die Stirn­seiten der Zigaretten 11 wirken. Die Prüforgane 30 sind vorzugsweise als optoelektrische Sensoren ausgebildet und mit Auswerteeinheiten 33 verbunden. Bei dem vorliegenden, bevorzugten Ausführungsbeispiel sind jeder Prüfreihe 26 zwei unmittelbar übereinander angeordnete Prüforgane 30 zugeordnet, so daß zwei übereinanderliegende Zigaretten 11 jeweils gleichzeitig geprüft werden, und zwar in einer Prüfebene 34.Within the test wells 28, the test rows 26 are moved past test organs 30 which are attached laterally to the housing 24, namely in side walls 31 and 32 of the housing 24, so that the test organs 30 act on the end faces of the cigarettes 11. The test organs 30 are preferably designed as optoelectric sensors and connected to evaluation units 33. In the present, preferred exemplary embodiment, each test row 26 is assigned two test organs 30 arranged directly one above the other, so that two cigarettes 11 one above the other are each tested simultaneously, specifically in one test plane 34.

Der untere Teil der Prüfeinheit 17 ist als Abgabe- und Ausstoßorgan 35 für die Zigaretten nach Durchführung der Prüfung ausgebildet. Dieses stellt sicher, daß die Ziga­retten 11 in den Prüfreihen 26 während der Prüfung, also während des momentanen Stillstands, der Höhe nach exakt auf die Prüforgane 30 ausgerichtet sind. Des weiteren er­folgt die Abgabe von geprüften und ordnungsgemäßen Ziga­retten an den Zigarettenvorrat 20, während etwa gleich­zeitig eine nächste Gruppe von (zwei) Zigaretten 11 ge­prüft wird.The lower part of the test unit 17 is designed as a delivery and ejection element 35 for the cigarettes after the test has been carried out. This ensures that the cigarettes 11 in the test rows 26 during the test, that is during the current standstill, the height is exactly aligned with the test organs 30. Furthermore, checked and correct cigarettes are delivered to the cigarette store 20, while a next group of (two) cigarettes 11 is checked approximately simultaneously.

Zu diesem Zweck besteht das Abgabe- und Ausstoßorgan 35 aus zwei in Querebenen relativ zueinander und zu dem übri­gen Teil der Prüfeinheit 17 bewegbaren Führungs- und Stütz­organen 36 und 37. Diese sind kammartig ausgebildet und bestehen aus den einzelnen Prüfschächten 28 zugeordneten Kammstegen 38 bzw. Stützstegen 39. Die Führungs- und Stützorgane 36, 37 bzw. deren Kammstege 38 bzw. Stütz­stege 39 sind nach Maßgabe der in den Fig. 4, 5 und 6 gezeigten Richtungspfeile 40 und 41 verschiebbar. Die Stege 38 und 39 sind mit gleicher Breite ausgebildet wie zwischen den Prüfschächten 28 gebildete Trennwände 42. Die Kammstege 38 unmittelbar unterhalb der Trennwände 42 sind mit einer Konstruktionshöhe ausgebildet, die der Höhe der Anzahl der gleichzeitig geprüften Zigaretten 11 je Prüfreihe 26 eintspricht, im vorliegenden Falle also der Höhe von zwei übereinanderliegenden Zigaretten. Das untere Führungs- und Stützorgan 37 mit den Stützstegen 39 ist demgegenüber mit geringerer Konstruktionshöhe ausge­bildet. Beide Führungs- und Stützorgane 36, 37 sind seit­lich aus dem Zigaretten-Magazin 12 herausgeführt und wer­den durch geeignete Organe angetrieben, z. B durch Druckmittelzylinder.For this purpose, the delivery and ejection member 35 consists of two guide and support members 36 and 37 which can be moved in transverse planes relative to one another and to the rest of the test unit 17. These are comb-shaped and consist of comb webs 38 or support webs assigned to the individual test wells 28 39. The guide and support members 36, 37 or their comb webs 38 or support webs 39 are displaceable in accordance with the directional arrows 40 and 41 shown in FIGS. 4, 5 and 6. The webs 38 and 39 are of the same width as the partition walls 42 formed between the test wells 28. The ridge webs 38 directly below the partition walls 42 are designed with a construction height that corresponds to the height of the number of cigarettes 11 tested simultaneously per test series 26, in the present case So drop the height of two stacked cigarettes. In contrast, the lower guide and support member 37 with the support webs 39 is designed with a lower construction height. Both guiding and supporting members 36, 37 are led out laterally from the cigarette magazine 12 and are driven by suitable members, e.g. B by pressure medium cylinder.

Die verschiedenen Stellungen und Funktionen der Führungs- und Stützorgane 36, 37 sind am besten unter Bezugnahme auf Fig. 4 bis 6 zu erläutern. Fig. 4 zeigt eine Relativ­stellung vor Beginn der Zigaretten-Prüfung. Die Kammstege 38 sind mit den Trennwänden 42 ausgerichtet, so daß sich die Prüfschächte 28 bis zu den Stützstegen 39 durchgehend erstrecken. Letztere sind versetzt zu den Kammstegen 38 bewegt, befinden sich demnach im Bereich der Prüfschächte 28, so daß die sich in diesen befindenden Zigaretten (Prüfreihe 26) auf den Stützstegen 39 aufliegen.The various positions and functions of the guiding and supporting members 36, 37 can best be explained with reference to FIGS. 4 to 6. 4 shows a relative position before the start of the cigarette test. The comb webs 38 are aligned with the partition walls 42, so that the test wells 28 extend all the way to the support webs 39. The latter are moved offset to the ridge webs 38 and are therefore located in the area of the test wells 28, so that the cigarettes located in them (test series 26) rest on the support webs 39.

Zur Durchführung der Prüfung werden die Kammstege 38 aus der Stellung gemäß Fig. 4 nach rechts bewegt in die Stel­lung gemäß Fig. 5. Die Kammstege 38 befinden sich nunmehr in der (Vertikal-)Ebene der Prüfschächte 28, so daß die sich oberhalb der Kammstege 38 befindenden Zigaretten auf den Kammstegen 38 abstützen. Die Relativstellung ist nun so gewählt, daß die Zigaretten in der Prüfebene 34 exakt auf die Prüforgane 30 ausgerichtet sind. Zugleich (Stel­lung gem. Fig. 5) sind auch die Stützstege 39 nach rechts verschoben. Sie befinden sich nun unterhalb der Trennwän­de 42 und dienen zur Abstützung der jeweils zwei überein­anderliegenden Zigaretten zwischen benachbarten Kammstegen 38. Diese bereits geprüften Zigaretten, einschließlich et­waiger Fehlzigaretten 18 sind mit den Kammstegen 38 in die gezeigte, versetzte Position bewegt worden. In der Posi­tion gemäß Fig. 5 werden die Fehlzigaretten 18 in Axial­richtung aus dem Zigaretten-Magazin 12 herausgefördert.To carry out the test, the comb webs 38 are moved from the position shown in FIG. 4 to the right into the position shown in FIG. 5. The comb webs 38 are now in the (vertical) plane of the test wells 28, so that they are above the comb webs Support 38 cigarettes on the ridges 38. The relative position is now selected so that the cigarettes in the test plane 34 are exactly aligned with the test organs 30. At the same time (position according to FIG. 5), the support webs 39 are also shifted to the right. They are now located below the partition walls 42 and serve to support the two superposed cigarettes between adjacent comb webs 38. These cigarettes which have already been checked, including any missing cigarettes 18, have been moved with the comb webs 38 into the offset position shown. In the position according to FIG. 5, the missing cigarettes 18 are conveyed out of the cigarette magazine 12 in the axial direction.

In der Stellung gemäß Fig. 6 werden die geprüften, in­takten Zigaretten 11 an den Zigarettenvorrat 20 übergeben. Zu diesem Zweck werden die Stützstege 39 aus der Position gemäß Fig. 5 querverschoben unter Öffnung der durch die Kammstege 38 begrenzten Teilschächte. Die sich in diesen befindenden Zigaretten können nunmehr nach unten ausgeworfen werden. Bei dem dargestellten Ausführungsbei­spiel sind zu diesem Zweck in den Trennwänden 42 Blas­düsen 43 angeordnet. Da sich die abzugebenden Zigaretten im Bereich unterhalb der Trennwände 42 befinden, werden die Blasdüsen 43 bzw. die von diesen abgegebene Druckluft unmittelbar im Sinne eines Austragens der Zigaretten wirk­sam. Wie aus Fig. 2 ersichtlich, sind in jeder Trennwand 42 zwei Blasdüsen 43 mit Abstand voneinander angeordnet. Diese werden über einen gemeinsamen Druckluftanschluß 44 versorgt.6, the tested, intact cigarettes 11 are transferred to the cigarette store 20. For this purpose, the support webs 39 are displaced transversely from the position according to FIG. 5, opening the partial shafts delimited by the comb webs 38. The cigarettes in these can now be ejected downwards. In the illustrated embodiment, for this purpose 42 blow nozzles 43 are arranged in the partition walls. Since the cigarettes to be dispensed are located in the area below the dividing walls 42, the blowing nozzles 43 or the compressed air emitted by them are effective immediately in the sense of discharging the cigarettes. As can be seen from FIG. 2, two blowing nozzles 43 are arranged at a distance from one another in each partition wall 42. These are supplied via a common compressed air connection 44.

Nach Abgabe der geprüften Zigaretten gemäß Fig. 6 wird das Führungs- und Stützorgan 36 mit den Kammstegen 38 in die Stellung gemäß Fig. 4 zurückbewegt. Dadurch können in jedem Prüfschacht 28 zwei Zigaretten nach unten nach­fallen bis zur Anlage auf den gegenüber Fig. 6 unverän­derten Stützstegen 39.After delivery of the tested cigarettes according to FIG. 6, the guide and support member 36 with the comb webs 38 is moved back into the position according to FIG. 4. As a result, two cigarettes can fall down in each test shaft 28 until they rest on the support webs 39, which are unchanged from FIG. 6.

Die vorliegende Ausführungsform der Vorrichtung ist hin­sichtlich der Prüfung der Zigaretten 11 sowie des Durch­satzes derselben durch die Prüfeinheit 17 auf zweier Gruppen ausgerichtet. Die Prüfebene 34 ist mit Abstand - entsprechend dem Durchmesser von zwei Zigaretten - oberhalb der Abgabeebene 19 angeordnet. Die geprüften Zigaretten gelangen damnach erst nach zwei Fördertakten in den Bereich des Abgabe- und Ausstoßorgans 35.The present embodiment of the device is oriented towards two groups with regard to the testing of the cigarettes 11 and the throughput thereof through the testing unit 17. The test level 34 is arranged at a distance - corresponding to the diameter of two cigarettes - above the delivery level 19. According to this, the tested cigarettes only reach the area of the delivery and ejection organ 35 after two production cycles.

Die relativ zueinander bewegbaren Führungs- und Stützorgane 36, 37 sind, wie in Fig. 2 gezeigt, außerhalb des Zigaretten-­Magazins 12 neben der Seitenwand 32 auf zwei parallelen Tragstangen 45, 46 verschiebbar gelagert und gestützt. Die Seitenwand 32 ist in diesem Bereich mit einer Ausneh­mung 47 für den Durchtritt der Führungs- und Stützorgane 36, 37 versehen.The guide and support members 36, 37, which are movable relative to one another, are, as shown in FIG. 2, displaceably mounted and supported outside of the cigarette magazine 12 next to the side wall 32 on two parallel support rods 45, 46. The side wall 32 is provided in this area with a recess 47 for the passage of the guide and support members 36, 37.

Der Ausstoß der Fehlzigaretten 18 im Bereich des Führungs- und Stützorgans 36 kann auf verschiedene Weise erfolgen. Im vorliegenden Falle sind zwei übereinander liegende Aus­werferdüsen 48, 49 in der Seitenwand 32 des Zigaretten-­Magazins 12 angeordnet, und zwar jeweils in Höhe und in Position der geprüften Zigaretten zwischen den Kammstegen 38. Auf der gegenüberliegenden Seite ist eine Auswerfer­öffnung 50 in der Seitenwand 31 vorgesehen.The ejection of the missing cigarettes 18 in the area of the guiding and supporting member 36 can take place in various ways. In the present case, two ejector nozzles 48, 49 lying one above the other are arranged in the side wall 32 of the cigarette magazine 12, in each case in the height and position of the tested cigarettes between the comb webs 38. On the opposite side there is an ejector opening 50 in the side wall 31 intended.
