Abstract

The cutting device proposed has a cutter (4) held in a holder (5) which is moved up and down approximately vertically by a drive (13), the tobacco bale being fed towards the cutter (4) by a feed device (1). The cutter holder (5) is moved by means of a set of pulleys which pull it both upwards and downwards, the moving pulleys (6, 7) being mounted on the cutter holder (5) and at least one (9) of the fixed pulleys (9, 10) being driven by a reversible motor (13). The usual hydraulic drive is thus replaced by a mechanical one, the pulley action enabling a traction system of relatively small dimensions to be used.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Abtrennung von Scheiben von Tabakballen oder ähnlichem gepressten Gut mittels eines Trennorganes, das in einem Träger gehalten ist, der von einem Antrieb annähernd vertikal auf- und abbewegbar ist, wobei der Tabakballen von einer Fördereinrichtung dem Trennorgan zugeführt wirdThe invention relates to a device for separating slices from tobacco bales or similar pressed material by means of a separating member which is held in a carrier which can be moved up and down approximately vertically by a drive, the tobacco bale being fed to the separating member by a conveying device

Für die Behandlung von Tabakballen sind Konditioniertrommeln bekannt, denen der Tabak in Scheiben zugeführt wird. Zur Abtrennung der Scheiben sind grundsätzlich zwei Arten von Vorrichtungen in Gebrauch, die den Tabakballen entweder in einer horizontalen oder einer vertikalen Ebene trennen.Conditioning drums are known for the treatment of tobacco bales, to which the tobacco is fed in slices. Basically, two types of devices are used to separate the slices, which separate the tobacco ball either in a horizontal or a vertical plane.

Bei der horizontalen Trennung wird der Tabakballen auf einen Hubtisch gefördert. Der Hubtisch positioniert den Ballen so, daß ein gabelartiges Trenn-organ eine Scheibe bestimmter Dicke vom Ballen abtrennt. Ein weiterer Schieber befördert die abgetrennte Scheibe dann durch einen Übergabeschacht in die Konditioniertrommel.With the horizontal separation, the tobacco bale is conveyed to a lifting table. The lifting table positions the bale so that a fork-like separating element separates a disc of a certain thickness from the bale. Another slider then conveys the separated slice through a transfer shaft into the conditioning drum.

Im Gegensatz dazu wird bei der vertikalen Trennung der Ballen mit einem Förderband oder einem Schieber auf einen Schneidtisch gefördert, an dessen Abgabeende ein Trennorgan angeordnet ist, das den Ballen von oben nach unten im wesentlichen vertikal durchschneidet. Die abgetrennten Scheiben fallen auf ein nachgeschaltetes Förderband.In contrast, the vertical separation of the bales is conveyed to a cutting table by means of a conveyor belt or a pusher, at the discharge end of which a separating element is arranged which cuts the bale essentially vertically from top to bottom. The separated slices fall onto a downstream conveyor belt.

Es hat sich gezeigt, daß durch das vertikale Trennen ein besser zu verarbeitender Tabak hergestellt werden kann, sodaß diese Art der Trennung viel-fach bevorzugt wird.It has been shown that tobacco can be processed better by vertical separation, so that this type of separation is preferred many times.

Bei bekannten Vorrichtungen der beschriebenen Art wird als Antrieb ein hydraulisch betätigtes Zylinder-Kolbenaggregat verwendet. Nachteilig hiebei ist, daß einerseits an der Oberseite der Vorrichtung verhältnismäßig viel Platz für das Aggregat erforderlich ist, andererseits die Gefahr besteht, daß bei einer Undichtheit im Aggregat die Tabakballen bzw. die davon abgeschnittenen Scheiben beschmutzt und damit unbrauchbar werden.In known devices of the type described, a hydraulically operated cylinder-piston unit is used as the drive. The disadvantage here is that, on the one hand, a relatively large amount of space is required for the unit at the top of the device, and on the other hand, there is a risk that if there is a leak in the unit, the tobacco balls or the slices cut from them will become dirty and therefore unusable.

Es ist auch schon eine Vorrichtung zum Abtrennen von Scheiben von einem Tabakballen bekannt geworden (SIEHE z.B. DE-B-1139419), bei der mehrere Trennmesser an zwei endlosen Zugmitteln befestigt sind, wobei diese Zugmittel über oberhalb und unterhalb der Fördereinrichtung angebrachte Umlenkrollen derart geführt sind, daß das oder die Trennmesser auf den rücklaufenden Trumen der Zugmittel die Stirnfläche des sich vorwärts bewegenden Tabakballens nicht berührt bzw. berühren.A device for severing slices from a tobacco bale has also become known (SEE DE-B-1139419, for example), in which several severing knives are attached to two endless traction means, these traction means being guided in this way over deflection rollers attached above and below the conveying device that the cutting knife or blades on the returning run of the traction means the end face of the Do not touch or touch the forward moving bale of tobacco.

Die Trennmesser dieser bekannten Vorrichtung laufen daher immer in der gleichen Richtung um, sodaß unterhalb der Fördereinrichtung viel Platz für die Umlenkung der Zugmittel erforderlich ist. Überdies müssen die Zugmittel wegen der auftretenden Beanspruchungen sehr stark dimensioniert sein.The cutting knives of this known device therefore always run in the same direction, so that a lot of space is required below the conveyor for deflecting the traction means. In addition, the traction means must be very large because of the stresses that occur.

Die Erfindung hat es sich zum Ziel gesetzt, eine Vorrichtung der eingangs genannten Art zu schaffen, die die Nachteile der bekannten Vorrichtungen mit auf- und abbewegbaren Trennorganen nicht aufweist. Erreicht wird dies dadurch, daß der Träger mittels eines sowohl nach oben als auch nach unten wirkenden Flaschenzuges bewegbar ist, wobei die losen Rollen des Flaschenzuges auf dem Träger gelagert sind und wenigstens eine der festen Rollen von einem um-steuerbaren Motor angetrieben ist.The invention has set itself the goal of creating a device of the type mentioned, which does not have the disadvantages of the known devices with up and down movable separators. This is achieved in that the carrier can be moved by means of a pulley which acts both upwards and downwards, the loose rollers of the pulley system being mounted on the carrier and at least one of the fixed rollers being driven by a reversible motor.

Bei einer erfindungsgemäßen Vorrichtung wird der hydraulische Antrieb durch einen mechanischen ersetzt, sodaß die geschilderten Nachteile der hydraulischen Antriebe nicht mehr auftreten können. Zufolge der Flaschenzugwirkung des mechanischen Antriebes nach der Erfindung können auch dessen Zugorgane schwächer, d.h. im Rahmen der Gesamtvorrichtung annehmbar, dimensioniert werden.In a device according to the invention, the hydraulic drive is replaced by a mechanical one, so that the disadvantages of the hydraulic drives described can no longer occur. Due to the pulley effect of the mechanical drive according to the invention, its traction elements can also be weaker, i.e. be acceptable within the scope of the overall device.

Es hat sich im Rahmen der Erfindung als zweckmäßig erwiesen, wenn das Zugorgan des Flaschenzuges als Gelenkkette ausgebildet ist und die Rollen Kettenräder sind.It has proven to be expedient in the context of the invention if the pulling element of the pulley is designed as an articulated chain and the rollers are sprockets.

Eine besonders kompakte Anordnung ergibt sich, wenn das Zugorgan von einem oberen Festpunkt über eine lose Rolle am Träger, weiters eine obere feste Rolle, eine untere feste Rolle und eine zweite lose Rolle am Träger zu einem unteren Festpunkt geführt ist.A particularly compact arrangement results when the traction element is guided from an upper fixed point via a loose roller on the carrier, furthermore an upper fixed roller, a lower fixed roller and a second loose roller on the carrier to a lower fixed point.

Zweckmäßig ist dabei die obere feste Rolle mit dem Antrieb verbunden.The upper fixed roller is expediently connected to the drive.

Nachstehend ist die Erfindung anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher beschrieben, ohne jedoch auf dieses Beispiel beschränkt zu sein. Dabei zeigt Fig. 1 in Seitenansicht schematisch eine erfindungsgemäße Vorrichtung und Fig. 2 stellt in schaubildlicher Ansicht das Prinzip der Anordnung nach der Erfindung dar.The invention is described in more detail below with reference to an exemplary embodiment shown in the drawings, but without being restricted to this example. 1 schematically shows a device according to the invention in a side view, and FIG. 2 shows a diagrammatic view of the principle of the arrangement according to the invention.

Gemäß Fig. 1 weist eine Vorrichtung zur Abtrennung von Scheiben von Tabakballen ein Förderband 1 auf, mittels dem die Tabakballen der eigentlichen Trennvorrichtung 2 zugeführt werden. Die abgetrennten Scheiben fallen auf ein Förderband 3, das die Scheiben einer Konditioniervorrichtung zuführt.1, a device for separating slices from tobacco bales has a conveyor belt 1, by means of which the tobacco bales are fed to the actual separating device 2. The separated slices fall onto a conveyor belt 3, which feeds the slices to a conditioning device.

Die Trennvorrichtung 2 besitzt als Trennorgan ein Messer 4, das in einem Träger 5 gehalten ist. Dieser Träger 5 ist in seitlichen Führungen 6 in einer im wesentlichen vertikalen Ebene auf- und abbewegbar geführt. An jeder Seite des Trägers 5 sind je zwei Kettenräder 6 und 7 gelagert, die die losen Rollen eines Flaschenzuges bilden. Über diese Kettenräder 6 und 7 ist je ein als Gelenkkette 8 ausgebildetes Zugorgan geführt. Die Enden jeder Gelenkkette 8 sind zu Festpunkten 11 und 12 geführt, der Mittelteil über als feste Rollen wirkende Kettenräder 9 und 10 geschlungen.The separating device 2 has a knife 4 as a separating member, which is held in a carrier 5. This carrier 5 is guided up and down in lateral guides 6 in a substantially vertical plane. On each side of the carrier 5 two sprockets 6 and 7 are mounted, which form the loose rollers of a pulley. About each chain sprockets 6 and 7 is designed as a link chain 8 traction member. The ends of each link chain 8 are guided to fixed points 11 and 12, the middle part looped over chain wheels 9 and 10 acting as fixed rollers.

Die oberen festen Kettenräder 9 werden von einem umsteuerbaren Getriebemotor 13 angetrieben.The upper fixed sprockets 9 are driven by a reversible gear motor 13.

In Fig. 1 ist überdies eine schwenkbare Messerabdeckung 14 sowie ein Sicherheitsbolzen 15 schematisch eingezeichnet.In Fig. 1, a pivotable knife cover 14 and a safety pin 15 is also shown schematically.

Es ist ohne weiteres ersichtlich, daß bei Antrieb durch den Getriebemotor 13 der Träger 5 und damit das Messer 4 auf- und abbewegt wird. Die über die Gelenkketten 8 zu übertragenden Kräfte sind bei Vernachlässigung der Reibung dabei nur halb so groß wie bei einem direkten Angriff der Ketten 8 am Träger 5.It is readily apparent that the carrier 5 and thus the knife 4 is moved up and down when driven by the gear motor 13. When the friction is neglected, the forces to be transmitted via the articulated chains 8 are only half as great as when the chains 8 directly engage the carrier 5.

Zahlreiche Abänderungen DES DARGESTELLTEN AUSFÜHRUNGSBEISPIELES sind möglich. So könnte statt des Förderbandes 1 zur Zuführung der Tabakballen in bekannter Weise ein Schieber verwendet werden.Numerous changes to the EXAMPLE EMBODIMENT represented are possible. So instead of the conveyor belt 1 for feeding the tobacco bale, a slide could be used in a known manner.
