Description

Die Erfindung betritt einen Tabakschneider mit einer motorisch angetriebenen Messertrommel und motorisch angetriebenen, aus Zwei zur Messetrommel hin konvergierenden Preßketten bestehenden Preßfördermitteln, an deren oberer Preßkette im Bereich des konvergierenden Mundstückendes der Preßfördermittel eine Preßvorrichtung angreift.The invention enters a tobacco cutter with a motorized knife drum and motor-driven, two converging towards the fair drum Press chains existing press conveyor, on their upper press chain a pressing device in the region of the converging mouthpiece end of the pressing conveyor attacks.

Der Erfindung liegt die Aufgabe zugrunde, die Preßvorrichtung bei einem Tabakschneider der eingangs bezeichneten Art baulich und funktionsmäßig zu verbessern.The invention has for its object the pressing device in a tobacco cutter improve the construction and function of the type described at the beginning.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Preßvorrichtung in ein hydropneumatisches Druckübertragungssystem integriert ist.
Gemäß einer vorteilhatten Ausgestaltung weist das hydro-pneumatische Druckübertragungssystem ein geschlossenes Hydrauliksystem mit das Mundstückende der Preßketten beaufschlagenden, an einen Hydraulikzylinder angeschlossenen Preßzylindern sowie einen mit dem Hydraulikzylinder in Wirkverbindung stehenden Pneumatikzylinder auf. Auf diese Weise wird ein System geschaffen, dessen kleinbauende Komponenten zum Teil direkt dem Tabakschneider eingefügt werden können und dessen übrige Komponenten eine flexible ortsunabhängige Unterbringung ermöglichen.
Eine vorteilhafte Verknüpfung der zusammenwirkenden Komponenten wird gemäß einer Weiterbildung dadurch errericht, daß die Wirkverbindung zwischen dem Pneumatikzylinder und dem Hydraulikzylinder eine den hydraulischen Preßdruck steigernde mechanische Kraftübersetzung umfaßt.
Eine zweckemäßige Weiterbildung der mechanischen Kraftübersetzung besteht darin, daß der Pneumatikzylinder und der Hydraulikzylinder durch zwei mit unterschliedlich langen Hebelarmen versehene, sich drehgelenkig an einem ortsfesten Lager abstützende Kipphebel verbunden sind.
Die erfindungsgemäßen Maßnahmen fügen sich auf vorteilhafte und effiziente Weise in ein Gesamtsystem ein, bei dem nach einem weiteren Vorschlag die Messertrommel und die Preßfördermittel mit separaten, elektromotorischen Antriebsmitteln ausgestattet sind.This object is achieved in that the pressing device is integrated in a hydropneumatic pressure transmission system.
According to an advantageous embodiment, the hydro-pneumatic pressure transmission system has a closed hydraulic system with press cylinders which act on the mouthpiece end of the press chains and are connected to a hydraulic cylinder, and a pneumatic cylinder which is operatively connected to the hydraulic cylinder. In this way, a system is created, the small components of which can partly be inserted directly into the tobacco cutter and the remaining components of which enable flexible location-independent accommodation.
According to a further development, an advantageous combination of the interacting components is achieved in that the operative connection between the pneumatic cylinder and the hydraulic cylinder comprises a mechanical force transmission which increases the hydraulic pressing pressure.
An expedient development of the mechanical power transmission is that the pneumatic cylinder and the hydraulic cylinder are connected by two rocker arms provided with differently long lever arms which are pivotally supported on a fixed bearing.
The measures according to the invention fit into an overall system in an advantageous and efficient manner, in which, according to a further proposal, the knife drum and the press conveying means are equipped with separate, electromotive drive means.

Der mit Der Erfindung erzielte Vorteil besteht darin, daß die dem Schneider unmittelbar zugeordneten Komponenten der Preßvorrichtung platzsparend integriert werden können, und daß weniger bewegte Teile der Preßvorrichtung längerfristig eine hohe Funktionssicherheit und Sicherheit gegen Leckageverluste des Hydrauliksystems gewährleisten.The advantage achieved with the invention is that the cutter immediately associated components of the pressing device integrated to save space can be, and that less moving parts of the pressing device in the long term high functional reliability and security against leakage losses of the hydraulic system guarantee.

Die Erfindung wird nachstehend anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to the embodiment shown in the drawing explained in more detail.

Die Figur zeigt schematisch einen Tabakschneider im Längsschnitt.The figure schematically shows a tobacco cutter in longitudinal section.

Der dargestellte Tabakschneider weist einen mit Tabak in Form von Blattgut 1 beschickbaren vertikalen Vorratsschacht 2 auf, in welchem rückseitig ein taktweise hin- und herschwingender Rechen 3 angeordnet ist. Der Vorratsschacht 2 geht in ein sich im wesentlichen horizontal erstreckendes Preßfördermittel 4 über, bestehend aus zwei in Förderrichtung (Pfeile 6) zueinander konvergierenden Preßketten 7 und 8, die den Tabak zu einem Kuchen 5 verdichten und die ausgangsseitig nahe einer mit Messern 9 besetzten Messertrommel 11 mit einem aus einem Oberteil 12 und einem Unterteil 13 bestehenden Mundstück 14 versehen sind, wobei das Unterteil 13 das Gegenmesser für die Messer 9 der Messertrommel 11 bildet.
aus Tabakfasern 15 vom Tabakkuchen 5 abgeschnitten und abgefördert werden. Zum Schleifen der Messer 9 dient eine Schleifscheibe 18, die von einem Diamanten 19 abgerichtet wird.The tobacco cutter shown has a vertical storage shaft 2 which can be loaded with tobacco in the form of sheet material 1, in which a rake 3 oscillating in cycles is arranged on the back. The storage chute 2 merges into a substantially horizontally extending press conveyor 4, consisting of two press chains 7 and 8 converging towards one another in the conveying direction (arrows 6), which compress the tobacco into a cake 5 and close on the output side to a knife drum 11 equipped with knives 9 are provided with a mouthpiece 14 consisting of an upper part 12 and a lower part 13, the lower part 13 forming the counter knife for the knives 9 of the knife drum 11.
cut from tobacco fibers 15 from tobacco cake 5 and removed. A grinding wheel 18, which is dressed by a diamond 19, is used to grind the knives 9.

Die obere Preßkette 7 mit dem Mundstückoberteil 12 ist als um eine Achse 21 drehbare Schwinge ausgebildet, an die zum Aufbringen eines Preßdruckes eine Preßvorrichtung in Form einer Kolbenstange 22 eines hydraulischen Preßzylinders 23 angreift, von dem ein zweiter, auf nicht dargestellte Weise auf der entgegengesetzten Seite (senkrecht zur Zeichenebene gesehen) der Preßkette 7 angreift. Die Preßzylinder 23 sind an einen gemeinsamen Hydraulikzylinder 24 angeschlossen und bilden mit diesem ein geschlossenes Hydrauliksystem 26, welches baulich unmittelbar mit dem Tabakschneider verbunden ist.The upper press chain 7 with the upper mouthpiece part 12 is about an axis 21 rotatable rocker formed, to which to apply a pressing pressure Press device in the form of a piston rod 22 of a hydraulic press cylinder 23 attacks, of which a second, in a manner not shown on the opposite Side (seen perpendicular to the plane of the drawing) of the press chain 7 attacks. The Press cylinders 23 are connected to a common hydraulic cylinder 24 and form with it a closed hydraulic system 26, which is structurally is directly connected to the tobacco cutter.

An einer Kolbenstange 27 des Hydraulikzylinders 24 greifen drehgelenkig zwei Kipphebel 28 und 29 an, die zur mechanischen Kraftübersetzung unterschiedlich lange Hebelarme 31, 32 aufweisen und sich drehgelenkig an einem ortsfesten Lager 33 abstützen sowie drehgelenkig mit der Kolbenstange 34 eines Pneumatikzylinders 36 verbunden sind.Two pivotally engage two piston rods 27 of the hydraulic cylinder 24 Rocker arms 28 and 29, which differ for mechanical power transmission have long lever arms 31, 32 and are pivotally attached to a stationary one Support bearing 33 and pivotally with the piston rod 34 of a pneumatic cylinder 36 are connected.

Auf diese Weise bilden das Hydrauliksystem 26 und der Pneumatikzylinder 36, welcher mit seiner Druckluftversorgung und seinen nicht weiter dargestellten pneumatischen Steuerungskomponenten außerhalb des Tabakschneiders untergebracht werden kann, ein effektives und funktionssicheres hydro-pneumatisches Druckübertragungssstem 37.In this way, the hydraulic system 26 and the pneumatic cylinder 36, which with its compressed air supply and its not shown pneumatic control components housed outside the tobacco cutter can be an effective and reliable hydro-pneumatic Pressure transmission system 37.
