- conveyor drums which are primarily drums of cigarette manufacturing machines or filter attaching machines, usually with suction air.
- cigarettes can be arranged next to one another in two essentially parallel rows on the conveyor drums and moved on the conveyor drums at right angles with respect to the cigarette axes.
- cigarettes are mostly produced in so-called double-filter cigarette units, ie in units of two cigarettes with a double filter attached between them, ie a filter or filter rod of double the useful length.
- double-filter cigarette units ie in units of two cigarettes with a double filter attached between them, ie a filter or filter rod of double the useful length.
- cut, double-length tobacco sticks are spread axially on the conveyor drum and a double-length filter rod is inserted between these two tobacco sticks or cigarettes.
- a conveyor drum that enables such a spreading of the tobacco sticks is, for example, from the DE 103 49 967 B4 known.
- these double filter cigarettes are divided into two filter cigarettes by dividing them in the middle of the double filter.
- filter cigarettes have to be aligned in order to pack them, ie have to be aligned in such a way that all filters or mouthpieces are on the same side, at least the filter cigarettes of a lane have to be turned over.
- the devices and methods mentioned at the beginning for turning rod-shaped objects were created for this turning process.
- the EP 1 050 222 B1 describes, for example, a device in which several cigarettes can be turned parallel to one another at the same time. Such devices can also be referred to as segment turner.
- Existing devices for turning rod-shaped objects are mostly mechanically complex constructions with a large number of expensive, mechanically complex components.
- a device for turning rod-shaped objects of the tobacco processing industry comprising a turning drum with a drum shaft driven by a drum drive and with at least one turning segment which has at least two receptacles for has turning rod-shaped objects, and which is arranged so as to be rotatable relative to the turning drum about an axis of rotation that upon rotation of the turning segment in the at least two receptacles, objects arranged in the at least two receptacles are turned essentially parallel to one another, an additional electrical drive device which is arranged and designed, to drive the at least one turning segment, characterized in that the additional electrical drive device is arranged and designed to drive the at least one turning segment via a transmission.

Derartige Vorrichtungen und Verfahren sind aus dem Stand der Technik bekannt. Zumeist werden sie bei der Zigarettenherstellung verwendet. Zigaretten werden meist quer zu ihrer längsaxialen Ausrichtung auf Fördertrommeln, bei denen es sich in erster Linie um Trommeln von Zigarettenherstellungsmaschinen bzw. von Filteransetzmaschinen handelt, in der Regel mit Saugluft gehalten. Auf den Fördertrommeln können in der Regel nebeneinander in zwei im Wesentlichen parallelen Reihen Zigaretten angeordnet und auf den Fördertrommeln rechtwinklig mit Bezug zu den Zigarettenachsen bewegt werden.Such devices and methods are known from the prior art.

Diese Vorrichtung sieht zunächst eine Wendetrommel mit einer drehbaren, durch einen Trommelantrieb angetriebenen Trommelwelle vor. Die Trommelwelle kann mechanisch angetrieben sein, beispielsweise durch einen als Zahnrad- oder Zahnriemengetriebe ausgebildeten Trommelantrieb. Die Trommelwelle kann auch durch einen elektrischen, meist an einem Maschinengestell fixierten und als Einzelantrieb ausgebildeten, Trommelantrieb angetrieben sein. Die Wendetrommel weist mindestens ein bewegliches, insbesondere um eine, vorzugsweise radial zur Trommelwelle ausgerichtete, Rotationsachse drehbares, Wendesegment auf. Vorzugsweise sind mehrere, insbesondere vier, Wendesegmente vorgesehen.This device initially provides a turning drum with a rotatable drum shaft driven by a drum drive. The drum shaft can be driven mechanically, for example by a drum drive designed as a gear or toothed belt drive. The drum shaft can also be driven by an electrical drum drive, usually fixed on a machine frame and designed as an individual drive. The turning drum has at least one movable turning segment, in particular rotatable about an axis of rotation that is preferably oriented radially to the drum shaft. Several, in particular four, turning segments are preferably provided.
Das mindestens eine Wendesegment weist mindestens zwei Aufnahmen für zu wendende stabförmige Gegenstände auf, um diese parallel zueinander, vorzugsweise sowohl zeitlich als auch örtlich parallel zueinander, zu wenden. Das zumindest eine Wendesegment kann vorzugsweise auch mehr als zwei Aufnahmen aufweisen, so dass auch mehr als zwei stabförmige Gegenstände, insbesondere eine Gruppe von Zigaretten, gemeinsam parallel zueinander gewendet werden kann bzw. können.The at least one turning segment has at least two receptacles for rod-shaped objects to be turned in order to turn them parallel to one another, preferably both temporally and spatially parallel to one another. The at least one turning segment can preferably also have more than two receptacles, so that more than two rod-shaped objects, in particular a group of cigarettes, can or can be turned together parallel to one another.
Das mindestens eine Wendesegment ist vorzugsweise am Umfang der Wendetrommel vorgesehen. Das mindestens eine Wendesegment ist um eine Drehachse drehbar angeordnet, wobei die Drehachse vorzugsweise bezogen auf die Wendetrommel radial ausgerichtet ist. Die Drehung des Wendesegments bewirkt, dass die in den mindestens zwei Aufnahmen angeordneten Gegenstände parallel zueinander gewendet werden. Vorzugsweise erfolgt dies bei einer Drehung des Wendesegments um 180 Grad, und vorzugsweise bei einer vollen Umdrehung der Wendetrommel. Wenn mehrere Wendesegmente vorgesehen sind, kann bevorzugt sein, dass benachbarte Wendesegmente in entgegengesetzter Richtung drehen und ein Wendesegment seine Drehung erst dann beginnt, wenn ein benachbartes Wendesegment eine Drehung um eine Mindestgradzahl bereits ausgeführt hat, wie beispielsweise in der
Die Erfindung beruht unter anderem auf der Erkenntnis, dass das mindestens eine Wendesegment durch eine elektrische Antriebsvorrichtung angetrieben werden kann. Dies hat gegenüber existierenden Vorrichtungen den Vorteil, dass mechanisch aufwändige, häufig ölgeschmierte Getriebe zum Realisieren der Wendebewegung, insbesondere der Drehung, des Wendesegments nicht mehr oder zumindest in deutlich geringerem Maße erforderlich sind. Vorzugsweise ist eine Steuerungsvorrichtung zur Ansteuerung der elektrischen Antriebsvorrichtung vorgesehen, die eine Drehung des Wendesegments, vorzugsweise in Abhängigkeit von der Trommelposition, insbesondere des Drehwinkels der Wendetrommel um ihre Längsachse, steuert.The invention is based, inter alia, on the knowledge that the at least one turning segment can be driven by an electric drive device. This has the advantage over existing devices that mechanically complex, often oil-lubricated gears for realizing the turning movement, in particular the rotation, of the turning segment are no longer required, or at least to a significantly lesser extent. A control device is preferably provided for controlling the electric drive device, which controls a rotation of the turning segment, preferably as a function of the drum position, in particular the angle of rotation of the turning drum about its longitudinal axis.
Falls mehrere Wendesegmente vorgesehen sind, kann die elektrische Antriebsvorrichtung mehrere Wendesegmente antreiben oder es können alternativ mehrere elektrische Antriebsvorrichtungen vorgesehen sein, so dass jedes Wendesegment von einer eigenen elektrischen Antriebsvorrichtung angetrieben wird. Wenn im Folgenden auf ein Wendesegment und/oder eine elektrische Antriebsvorrichtung Bezug genommen wird, gelten die Ausführungen entsprechend auch für Ausgestaltungen der Vorrichtungen mit zwei oder mehreren Wendesegmenten und/oder zwei oder mehreren Antriebsvorrichtungen.If several turning segments are provided, the electric drive device can drive several turning segments or, alternatively, several electric drive devices can be provided so that each turning segment is driven by its own electric drive device. If reference is made in the following to a turning segment and / or an electric drive device, the explanations also apply accordingly to configurations of the devices with two or more turning segments and / or two or more drive devices.
Eine bevorzugte Ausgestaltung sieht vor, dass die elektrische Antriebsvorrichtung an der Trommelwelle befestigt ist. Die elektrische Antriebsvorrichtung ist ferner vorzugsweise derart an der Trommelwelle befestigt, dass sie mit der Trommelwelle umläuft, wenn die Trommelwelle vom Trommelantrieb angetrieben wird. Auf diese Weise, da auch das Wendesegment mit der Trommelwelle umläuft, erfolgt eine Rotation sowohl des Wendesegments als auch der elektrischen Antriebsvorrichtung um die Längsachse der Wendetrommel bzw. der Trommelwelle gemeinsam.A preferred embodiment provides that the electric drive device is attached to the drum shaft. The electric drive device is also preferably attached to the drum shaft in such a way that it rotates with the drum shaft when the drum shaft is driven by the drum drive. In this way, since the turning segment also rotates with the drum shaft, both the turning segment and the electric drive device rotate together around the longitudinal axis of the turning drum or the drum shaft.
Alternativ kann die elektrische Antriebsvorrichtung ortsfest, d.h. nicht drehend, angeordnet und ausgebildet sein, wobei keine elektrischen Signale in drehende Teile übertragen werden müssen. Die Drehbewegung des Wendesegments kann sich in einer solchen Ausgestaltung vorzugsweise aus der Überlagerung der Drehung der Trommelwelle und der Drehung der elektrischen Antriebsvorrichtung bzw. des Motors ergeben. Ein Eingangsrad eines Kegelgetriebes kann über ein Ritzel mit einem Motor angetrieben werden. Beim Vorsehen von vier Wendesegmenten können entsprechend vier Kegelräder ineinandergestaffelt auf einer Trommelantriebswelle oder einem Lagerflansch gelagert werden.Alternatively, the electric drive device can be arranged and designed to be stationary, that is to say non-rotating, with no electrical signals having to be transmitted to rotating parts. In such an embodiment, the rotary movement of the turning segment can preferably result from the superposition of the rotation of the drum shaft and the rotation of the electric drive device or the motor. An input gear of a bevel gear can be driven by a motor via a pinion. If four turning segments are provided, four bevel gears can be stored in a staggered manner on a drum drive shaft or a bearing flange.
Ferner ist bevorzugt, dass die elektrische Antriebsvorrichtung als Elektromotor ausgebildet ist. Ferner kann die elektrische Antriebsvorrichtung auch ein oder mehrere elektrische Funktionselemente, wie beispielsweise Sensoren, etwa Lichtschranken für die mindestens zwei Aufnahmen, beinhalten. Solche elektrischen Funktionselemente können auch zusätzlich zur elektrischen Antriebsvorrichtung vorgesehen sein.It is also preferred that the electric drive device is designed as an electric motor. Furthermore, the electrical drive device can also contain one or more electrical functional elements, such as sensors, for example light barriers for the at least two receptacles. Such electrical functional elements can also be provided in addition to the electrical drive device.
In einer weiteren bevorzugten Ausgestaltung ist vorgesehen, dass die Trommelwelle als Hohlwelle ausgebildet ist und eine Leitungsverbindung, vorzugsweise eine Kabelverbindung, von der elektrischen Antriebsvorrichtung durch die Hohlwelle aus der Wendetrommel hinausgeführt ist.In a further preferred embodiment it is provided that the drum shaft is designed as a hollow shaft and a line connection, preferably a cable connection, is led out of the turning drum from the electric drive device through the hollow shaft.
Vorzugsweise weist die Trommelwelle eine oder mehrere, vorzugsweise radiale, Öffnungen auf, durch die die Leitungsverbindung von der elektrischen Antriebsvorrichtung in das Innere der als Hohlwelle ausgebildeten Trommelwelle gelangen kann. Insbesondere falls mehrere elektrische Antriebsvorrichtungen vorgesehen sind oder neben einer oder mehren elektrischen Antriebsvorrichtungen weitere elektrische Funktionselemente, wie beispielsweise Sensoren, vorgesehen sind, hat die Herausführung einer oder mehrerer Leitungsverbindungen durch die Hohlwelle den Vorteil, dass der Raum innerhalb der Trommelwelle genutzt und die Leitungsverbindungen zentral aus der Wendetrommel herausgeführt werden können. Die Leitungsverbindung kann beispielsweise Versorgungs-, Steuerungs- und/oder Auswerteleitungen umfassen. Eine Versorgungsleitung kann beispielsweise die Versorgung mit (elektrischer) Energie oder anderer Medien, wie etwa Fluiden, beispielsweise Öl, Wasser oder Druckluft, beispielsweise zur Kühlung oder Schmierung der drehenden Trommel, beinhalten. An einem, vorzugsweise aus der Wendetrommel herausragenden, Ende der Hohlwelle ist vorzugsweise eine Drehdurchführung für Leitungsverbindungen vorgesehen. Die Leitungsverbindung wird durch die Hohlwelle aus der Wendetrommel vorzugsweise in einen Maschinenraum oder ein Maschinengestell geführt.The drum shaft preferably has one or more, preferably radial, openings through which the line connection from the electric drive device can pass into the interior of the drum shaft designed as a hollow shaft. In particular, if several electric drive devices are provided or, in addition to one or more electric drive devices, further electrical functional elements, such as sensors, are provided, leading one or more line connections through the hollow shaft has the advantage that the space inside the drum shaft is used and the line connections are centrally located the turning drum can be brought out. The line connection can include, for example, supply, control and / or evaluation lines. A supply line can contain, for example, the supply of (electrical) energy or other media, such as fluids, for example oil, water or compressed air, for example for cooling or lubricating the rotating drum. At one end of the hollow shaft, preferably protruding from the turning drum, a rotary leadthrough for line connections is preferably provided. The line connection is led through the hollow shaft from the turning drum, preferably into a machine room or a machine frame.
Ferner ist bevorzugt, dass die Trommelwelle aus der Wendetrommel hinausgeführt ist und außerhalb der Wendetrommel an der Trommelwelle ein Aufnahmeabschnitt angeordnet ist.It is also preferred that the drum shaft is led out of the turning drum and a receiving section is arranged outside the turning drum on the drum shaft.
Die Trommelwelle ist vorzugsweise aus der Wendetrommel hinausgeführt, so dass außerhalb der Wendetrommel, vorzugsweise in einem Maschinenraum oder an einem Maschinengestell, an der Trommelwelle ein, vorzugsweise mit der Trommelwelle mitdrehender, Aufnahmeabschnitt angeordnet ist. Der Aufnahmeabschnitt kann beispielsweise als sich radial von der Trommelwelle nach außen erstreckende Scheibe ausgebildet sein.The drum shaft is preferably led out of the turning drum, so that outside the turning drum, preferably in a machine room or on a machine frame, a receiving section, preferably rotating with the drum shaft, is arranged on the drum shaft. The receiving section can, for example be designed as a disc extending radially outward from the drum shaft.
Dabei ist ferner bevorzugt, dass an dem Aufnahmeabschnitt mindestens eine Versorgungs-, Steuer- und/oder Auswerteeinheit angeordnet ist, welche mit der elektrischen Antriebsvorrichtung und/oder einem oder mehreren elektrischen Funktionselementen, vorzugsweise über die durch die Hohlwelle geführte Leitungsverbindung, verbunden ist. Diese Ausgestaltung hat den Vorteil, dass sowohl die am Aufnahmeabschnitt angeordneten Einheiten ebenso wie die elektrische Antriebsvorrichtung bzw. die elektrischen Funktionselementen vorzugsweise mit der Trommelwelle mitdrehen, so dass vorzugsweise keine relative Rotationsbewegung zwischen der elektrischen Antriebsvorrichtung bzw. den elektrischen Funktionselementen und der mindestens einen Versorgungs-, Steuer- und/oder Auswerteeinheit erfolgen muss. Die mindestens eine Versorgungs-, Steuer- und/oder Auswerteeinheit ist vorzugsweise ausgebildet, um die elektrische Antriebsvorrichtung und/oder weitere, vorzugsweise elektrische, Funktionselemente, welche vorzugsweise an der Wendetrommel, insbesondere an der Trommelwelle und/oder am Wendesegment befestigt sind, zu verbinden. Insbesondere kann eine Versorgung mit (elektrischer) Energie und/oder Fluiden, wie beispielsweise Öl, Wasser oder Druckluft vorgesehen sein. Ebenso können Datenverbindungen zur Steuerung und/oder Auswertung der elektrischen Antriebsvorrichtung und/oder weiterer (elektrischer) Funktionselementen, wie Sensoren, vorgesehen sein.It is further preferred that at least one supply, control and / or evaluation unit is arranged on the receiving section, which is connected to the electrical drive device and / or one or more electrical functional elements, preferably via the line connection routed through the hollow shaft. This configuration has the advantage that both the units arranged on the receiving section and the electrical drive device or the electrical functional elements preferably rotate with the drum shaft, so that preferably no relative rotational movement between the electrical drive device or the electrical functional elements and the at least one supply , Control and / or evaluation unit must take place. The at least one supply, control and / or evaluation unit is preferably designed to connect the electrical drive device and / or further, preferably electrical, functional elements, which are preferably attached to the turning drum, in particular to the drum shaft and / or to the turning segment . In particular, a supply of (electrical) energy and / or fluids such as oil, water or compressed air can be provided. Data connections for controlling and / or evaluating the electric drive device and / or further (electric) functional elements, such as sensors, can also be provided.
In einer Steuereinheit ist vorzugsweise insbesondere ein Bewegungsgesetz des mindestens einen Wendesegments, vorzugsweise mehrerer Wendesegmente abgespeichert. Ferner vorzugsweise ist in der Steuereinheit die Information über die aktuelle Istlage der Wendetrommel, wie sie beispielsweise in einem Drehgeber des Trommelantriebs erfasst wird, vorhanden und wird zur Berechnung der Sollposition des mindestens einen Wendesegments herangezogen. Diese Sollposition des mindestens einen Wendesegments wird in der Steuereinheit vorzugsweise mit der Istposition des mindestens einen Wendesegments verglichen, welche ebenfalls beispielsweise über einen Drehgeber der elektrischen Antriebsvorrichtung erfasst werden kann. Aus diesem Vergleich errechnet die Steuereinheit vorzugsweise ein Steuersignal für die elektrische Antriebsvorrichtung. Wenn auch die Steuereinheit mitdrehend an der Trommelwelle befestigt ist, wird die Anzahl der von rotierenden auf nicht rotierende Einheiten zu übertragenden Daten bzw. Signale deutlich reduziert. Auf diese Weise kann zum einen der konstruktive Aufwand für die Signalübertragung und damit auch die Anzahl potentieller Störstellen reduziert und so die Zuverlässigkeit der Vorrichtung zum Wenden von stabförmigen Gegenständen erhöht werden.In particular, a law of motion of the at least one turning segment, preferably a plurality of turning segments, is preferably stored in a control unit. Furthermore, the information about the current actual position of the turning drum, as detected, for example, in a rotary encoder of the drum drive, is preferably present in the control unit and is used to calculate the target position of the at least one turning segment. This target position of the at least one turning segment is preferably compared in the control unit with the actual position of the at least one turning segment, which can also be detected, for example, via a rotary encoder of the electric drive device. From this comparison, the control unit preferably calculates a control signal for the electric drive device. If the control unit is also attached to the drum shaft while rotating, the number of data or signals to be transmitted from rotating to non-rotating units is significantly reduced. In this way, on the one hand, the structural effort for the signal transmission and thus also the number of potential interference points can be reduced and the reliability of the device for turning rod-shaped objects can be increased.
Insbesondere ist bevorzugt, dass an dem Aufnahmeabschnitt ein Schleifringübertrager angeordnet ist, der mit der mindestens einen an dem Aufnahmeabschnitt angeordneten Versorgungs-, Steuer- und/oder Auswerteeinheit verbunden ist. Vorzugsweise ist bzw. sind die mindestens eine elektrische Antriebsvorrichtung und/oder ein oder mehrere elektrische Funktionselemente über die Leitungsverbindung direkt oder indirekt, beispielsweise über eine Versorgungs-, Steuer- und/oder Auswerteeinheit mit dem Schleifringübertrager verbunden. Vorzugsweise besteht eine Leitungsverbindung zwischen einem rotierenden Teil des Schleifringübertragers und der ebenfalls mitdrehenden, durch die Hohlwelle geführten Leitungsverbindung und/oder der mindestens einen an dem Aufnahmeabschnitt angeordneten Versorgungs-, Steuer- und/oder Auswerteeinheit.In particular, it is preferred that a slip ring transmitter is arranged on the receiving section and is connected to the at least one supply, control and / or evaluation unit arranged on the receiving section. The at least one electrical drive device and / or one or more electrical functional elements is / are preferably connected to the slip ring transmitter via the line connection directly or indirectly, for example via a supply, control and / or evaluation unit. There is preferably a line connection between a rotating part of the slip ring assembly and the line connection, which also rotates with it and guided through the hollow shaft, and / or the at least one supply, control and / or evaluation unit arranged on the receiving section.
Diese Ausgestaltungen haben den Vorteil, dass die über den Schleifringübertrager zu übertragende Datenmenge minimiert werden kann, da beispielsweise die Steuerung eines oder mehrerer elektrischer Antriebsvorrichtungen durch mitdrehende Steuereinheiten erfolgen kann und/oder die Auswertung von einem oder mehreren an der Wendetrommel vorgesehenen elektrischen Funktionselementen, wie Sensoren, über ebenfalls mitdrehende Auswerteeinheiten erfolgen kann, so dass für die im laufenden Betrieb erfolgende Steuerung und/oder Auswertung keine oder nur eine minimierte Datenübertragung über den Schleifringübertrager erforderlich ist.These configurations have the advantage that the amount of data to be transmitted via the slip ring assembly can be minimized since, for example, one or more electrical drive devices can be controlled by co-rotating control units and / or one or more electrical functional elements, such as sensors, provided on the turning drum can be evaluated , can also take place via evaluation units that also rotate, so that no or only minimal data transmission via the slip ring assembly is required for the control and / or evaluation that takes place during operation.
Auf diese Weise kann eine Vielzahl von elektrischen Signalen durch auf der Trommelwelle mitdrehende Einheiten, beispielsweise steuerungstechnisch, verarbeitet werden. Die Zahl der Übertragungsspuren des Schleifringübertragers kann somit klein gehalten werden. Ein weiterer Vorteil besteht darin, dass, insbesondere durch das Vorsehen eines Aufnahmeabschnitts außerhalb der Wendetrommel, Versorgungs-, Steuer- und/oder Auswerteeinheiten, sowie sonstige Auswerteelektronik und/oder Energieversorgung in einem sauberen Maschinenraum bzw. Maschinengestell außerhalb der Wendetrommel angeordnet sein können. Ein weiterer Vorteil ergibt sich durch das Mitrotieren der Versorgungs-, Steuer- und/oder Auswerteeinheiten bzw. der Auswerteelektronik oder Energieversorgung insofern, dass durch die Drehbewegung dieser Einheiten eine aktive Luftkühlung erfolgt.In this way, a large number of electrical signals can be processed by units rotating on the drum shaft, for example in terms of control technology. The number of transmission tracks of the slip ring assembly can thus be kept small. Another advantage is that, in particular by providing a receiving section outside the turning drum, supply, control and / or evaluation units, as well as other evaluation electronics and / or power supply can be arranged in a clean machine room or machine frame outside the turning drum. A further advantage results from the fact that the supply, control and / or evaluation units or the evaluation electronics or power supply also rotate, insofar as active air cooling takes place through the rotary movement of these units.
In einer weiteren bevorzugten Ausgestaltung ist vorgesehen, dass das Getriebe ein Riemen- oder Kegelradgetriebe ist.In a further preferred embodiment it is provided that the transmission is a belt or bevel gear transmission.
Insbesondere als Alternative zu einem Direktantrieb kann beispielsweise der Einsatz eines Getriebemotors, etwa mit einem Winkelgetriebe bevorzugt sein. Durch eine Übersetzung in der Getriebestufe kann somit in vorteilhafter Weise eine kleinere Baugröße der elektrischen Antriebsvorrichtung realisiert werden. Der Einsatz eines Zahnriemengetriebes hat zudem insbesondere den Vorteil eines ölfreien Aufbaus.In particular, as an alternative to a direct drive, the use of a geared motor, for example with an angular gear, can be preferred. Through a translation In the gear stage, a smaller size of the electric drive device can thus be implemented in an advantageous manner. The use of a toothed belt drive also has the particular advantage of an oil-free structure.
Wie oben bereits erwähnt, ist ferner eine Ausgestaltung bevorzugt, bei der zwei, drei oder mehrere, vorzugsweise vier Wendesegmente vorgesehen sind, wobei vorzugsweise für den Antrieb jedes der Wendesegmente vorgesehen sind jeweils eine elektrische Antriebsvorrichtung vorgesehen ist, und wobei ferner vorzugsweise die elektrischen Antriebsvorrichtungen aller Wendesegmente an der Trommelwelle befestigt sind.As already mentioned above, an embodiment is also preferred in which two, three or more, preferably four, turning segments are provided, an electric drive device being provided for driving each of the turning segments, and preferably all of the electric drive devices being provided Turning segments are attached to the drum shaft.
In einer weiteren bevorzugten Ausgestaltung ist ferner vorgesehen, dass das mindestens eine Wendesegment derart ausgebildet und angeordnet ist, dass das mindestens eine Wendesegment bei Antrieb durch die elektrische Antriebsvorrichtung berührungsfrei zu benachbarten, weiteren Wendesegmenten und/oder benachbarten Maschinenelementen, wie beispielsweise benachbarten Trommeln, dreht.In a further preferred embodiment it is further provided that the at least one turning segment is designed and arranged in such a way that the at least one turning segment, when driven by the electric drive device, rotates without contact to neighboring, further turning segments and / or neighboring machine elements, such as neighboring drums.
Beim Drehen bzw. Rotieren des mindestens einen Wendesegments beim Antrieb durch die elektrische Antriebsvorrichtung ist es bevorzugt, dass keine Berührung oder Kollision mit benachbarten weiteren Wendesegmenten und/oder benachbarten Maschinenelementen erfolgt. Benachbarte Maschinenelemente können beispielsweise benachbarte Trommeln, wie etwa Zuführtrommeln, sein. Das Wendesegment ist vorzugsweise derart ausgebildet, dass es bei einer Drehung um seine Rotationsachse nicht mit benachbarten Maschinenelementen und/oder benachbarten Wendesegmenten in Berührung kommt.When turning or rotating the at least one turning segment when being driven by the electric drive device, it is preferred that there is no contact or collision with adjacent further turning segments and / or adjacent machine elements. Adjacent machine elements can be, for example, adjacent drums, such as feed drums. The turning segment is preferably designed in such a way that it does not come into contact with adjacent machine elements and / or adjacent turning segments when it rotates about its axis of rotation.
Vorzugsweise ist vorgesehen, dass das mindestens eine Wendesegment in einen Kugelabschnitt einschreibbar ist und/oder abgerundete Ecken aufweist. Vorzugsweise sind sämtliche Wendesegmente einer Vorrichtung in einer Kugel einschreibbar bzw. liegen innerhalb einer Kugelfläche, wobei vorzugsweise der Mittelpunkt der Kugel im Schnittpunkt der Drehachsen der Wendesegmente liegt.It is preferably provided that the at least one turning segment can be inscribed in a spherical segment and / or has rounded corners. Preferably, all of the turning segments of a device can be inscribed in a ball or are located within a spherical surface, the center point of the ball preferably being at the intersection of the axes of rotation of the turning segments.
Insbesondere ist der Abschnitt des mindestens einen Wendesegments in einen Kugelabschnitt einschreibbar und/oder weist abgerundete Ecken auf, der den Außenumfang der Wendetrommel bildet oder über diesen Außenumfang radial nach außen herausragt.In particular, the section of the at least one turning segment can be inscribed in a spherical section and / or has rounded corners, which forms the outer circumference of the turning drum or protrudes radially outward beyond this outer circumference.
Durch das Einschreiben des mindesten einen Wendesegments bzw. des zuvor genannten Abschnitts und/oder entsprechendes Abrunden von Ecken kann die Berührungs- bzw. Kollisionsfreiheit zu benachbarten Wendesegmenten und/oder benachbarten Maschinenelementen in besonders einfacher Weise realisiert werden. Insbesondere kann auf diese Weise realisiert werden, dass benachbarte Wendesegmente unabhängig voneinander ohne Kollisionsrisiko um ihre jeweilige Rotationsachse drehen können. Insbesondere ist bevorzugt, dass die Wendesegmente derart ausgebildet und angeordnet sind, dass benachbarte Wendesegmente unabhängig von einem Drehwinkel des jeweils anderen Wendesegments um mindestens 180 Grad, vorzugsweise um 360 Grad, um ihre jeweilige Drehachse drehen können, ohne mit dem jeweils anderen Wendesegment in Berührung zu kommen.By inscribing the at least one turning segment or the aforementioned section and / or correspondingly rounding corners, the freedom from contact or collision with adjacent turning segments and / or adjacent machine elements can be achieved can be implemented in a particularly simple manner. In particular, it can be realized in this way that adjacent turning segments can rotate around their respective axis of rotation independently of one another without the risk of collision. In particular, it is preferred that the turning segments are designed and arranged in such a way that adjacent turning segments can rotate independently of an angle of rotation of the other turning segment by at least 180 degrees, preferably 360 degrees, around their respective axis of rotation without coming into contact with the other turning segment come.
Ein solcher Aufbau bzw. eine solche Konstruktion der Wendesegmente kann eine Kollision der Wendesegmente untereinander vorzugsweise in jeder ihrer Positionen vermeiden. Vorzugsweise werden die Wendesegmente derart gestaltet, dass sie innerhalb einer Kugelfläche liegen. Vorzugsweise liegt der Mittelpunkt der Kugel in einem Schnittpunkt der Drehachsen der Wendesegmente. Auf diese Weise kann gewährleistet werden, dass sich die Wendesegmente während ihrer jeweiligen Rotation immer innerhalb der Kugel befinden. Je größer der Kugeldurchmesser gewählt werden kann, desto länger können auch die Aufnahmen ausgebildet sein, so dass sich die Länge der Auflage der stabförmigen Gegenstände in den Aufnahmen vergrößert. Bei einer detaillierten Konstruktion mit beispielsweise einer genauen Untersuchung der Kollisionsbedingungen kann vorzugsweise von einer exakten Kugelform abgewichen werden, um die Länge der Aufnahmen weiter zu vergrößern und gleichzeitig die Kollisionsfreiheit sicherzustellen. Ferner ist bevorzugt, eine benachbarte Trommel, insbesondere eine Einlegetrommel, im Bereich einer Maschinenmitte einzudrehen, wodurch ebenfalls die Länge der Aufnahmen der Wendesegmente erhöht werden kann.Such a structure or such a construction of the turning segments can avoid a collision of the turning segments with one another, preferably in each of their positions. The turning segments are preferably designed in such a way that they lie within a spherical surface. The center of the ball is preferably located at an intersection of the axes of rotation of the turning segments. In this way it can be ensured that the turning segments are always located within the sphere during their respective rotation. The larger the ball diameter that can be selected, the longer the receptacles can also be designed, so that the length of the support of the rod-shaped objects in the receptacles increases. In the case of a detailed construction with, for example, a precise examination of the collision conditions, an exact spherical shape can preferably be deviated from in order to further increase the length of the receptacles and at the same time ensure that there are no collisions. It is also preferred to screw in an adjacent drum, in particular an insert drum, in the area of the center of the machine, whereby the length of the receptacles of the turning segments can also be increased.
In einer weiteren Ausgestaltung ist bevorzugt, dass das mindestens eine Wendesegment einen Kurvenkörper aufweist, der in einer Kurvenbahn geführt ist. Dabei ist ferner bevorzugt, dass die Kurvenbahn derart ausgebildet und angeordnet ist, dass, vorzugsweise in jeder Position der Wendetrommel, das mindestens eine Wendesegment berührungsfrei zu benachbarten Wendesegmenten und/oder benachbarten Maschinenelementen angeordnet und ausgerichtet ist.In a further embodiment it is preferred that the at least one turning segment has a curved body which is guided in a curved path. It is further preferred that the curved path is designed and arranged in such a way that, preferably in every position of the turning drum, the at least one turning segment is arranged and aligned without contact with adjacent turning segments and / or adjacent machine elements.
Die Kurvenbahn ist vorzugsweise an der Trommelwelle oder mit dieser verbundenen Elementen angeordnet. Der Kurvenkörper ist vorzugsweise im Normalbetrieb frei, d.h. nicht zwangsgeführt, in der Kurvenbahn geführt. Wenn mehrere Wendesegmente vorgesehen sind, ist es ferner bevorzugt, dass entsprechend jedes Wendesegment einen Kurvenkörper, der in einer entsprechenden Kurvenbahn geführt ist, aufweist. Die Kurvenbahn bzw. die Kurvenbahnen ist bzw. sind vorzugsweise so angeordnet, dass sie eine gewollte Rotation der Wendesegmente um ihre jeweilige Rotationsachse erlauben und gleichzeitig verhindern, dass benachbarte Wendesegmente in Berührung kommen oder ein Wendesegment mit benachbarten Maschinenelementen, wie beispielsweise benachbarten Trommeln, wie Zuführtrommeln, in Berührung kommt. Dazu ist die Kurvenbahn vorzugsweise derart ausgebildet und angeordnet, dass ein Eingriff des Kurvenkörpers mit der Kurvenbahn, also eine Zwangsführung, vorzugsweise nur dann erfolgt, wenn eine Bewegung bzw. Rotation des Wendesegments bzw. der Wendesegmente zu einer Berührung benachbarter Wendesegmente und/oder benachbarter Maschinenelemente führen würde. Wenn mit der Kurvenbahn nicht nur die Kollisionsfreiheit des mindestens einen Wendesegments zu benachbarten Maschinenelementen sichergestellt werden soll, sondern gleichzeitig auch die Kollisionsfreiheit mehrerer benachbarter Wendesegmente sicher verhindert wird, können auch Wendesegmente eingesetzt werden, die - ohne das Vorsehen einer Kurvenbahn - nicht vollständig kollisionsfrei drehen könnten. Dadurch können sich Vorteile bei der Gestaltung der Wendesegmente ergeben, beispielsweise eine besser Luftführung, oder längere Aufnahmen für eine bessere Auflage der stabförmigen Gegenstände.The cam track is preferably arranged on the drum shaft or elements connected to it. In normal operation, the cam body is preferably guided freely, ie not positively guided, in the cam path. If a plurality of turning segments are provided, it is also preferred that each turning segment has a curved body that is guided in a corresponding curved path. The curved path or the cam tracks is or are preferably arranged in such a way that they allow a desired rotation of the turning segments around their respective axis of rotation and at the same time prevent adjacent turning segments from coming into contact or a turning segment from coming into contact with neighboring machine elements, such as neighboring drums, such as feed drums Touch comes. For this purpose, the cam track is preferably designed and arranged in such a way that the cam body engages the cam track, i.e. forced guidance, preferably only when a movement or rotation of the turning segment or the turning segments causes contact with adjacent turning segments and / or adjacent machine elements would lead. If the cam path is not only intended to ensure that the at least one turning segment is not collision-free with adjacent machine elements, but at the same time the freedom from collision of several neighboring turning segments is reliably prevented, turning segments can also be used which - without the provision of a cam path - could not turn completely collision-free . This can result in advantages in the design of the turning segments, for example better air guidance or longer receptacles for better support of the rod-shaped objects.
Ferner ist bevorzugt, dass mindestens ein Kollisionssensor vorgesehen ist, beispielsweise eine ortsfest angebrachte Lichtschranke, der angeordnet und ausgebildet ist, unerwünschte Bewegungen, Drehungen und/oder Positionen des mindestens einen Wendesegments zu detektieren und ferner vorzugsweise ein Kollisionssignal an die elektrische Antriebsvorrichtung und/oder den Trommelantrieb zu übermitteln, wobei vorzugsweise die elektrische Antriebsvorrichtung und/oder der Trommelantrieb in Abhängigkeit des Kollisionssignals gestoppt werden, um eine Kollision zu verhindern.It is also preferred that at least one collision sensor is provided, for example a stationary light barrier which is arranged and designed to detect undesired movements, rotations and / or positions of the at least one turning segment and also preferably a collision signal to the electric drive device and / or the To transmit drum drive, wherein preferably the electric drive device and / or the drum drive are stopped as a function of the collision signal in order to prevent a collision.

Der Elektromotor 4 treibt ein Wendesegment 5 derart an, dass das Wendesegment 5 um seine Rotationsachse dreht, die orthogonal zur Rotationsachse der Trommelwelle 2 und radial zu dieser verläuft.In the drum space, firmly connected to the
Eine als Kabelverbindung ausgebildete Leitungsverbindung 10 ist vom Elektromotor 4 durch das Innere der als Hohlwelle ausgebildeten Trommelwelle 2 vom Trommelraum in den rückwärtigen Maschinenraum geführt und tritt dort aus einer Öffnung in der Trommelwelle aus. An einem im rückwärtigen Maschinenraum befindlichen Ende der Trommelwelle 2 ist ein Aufnahmeabschnitt 6 angeordnet, der mit der Trommelwelle 2 mitrotiert und daher auch als Drehteller bezeichnet werden kann. An dem Aufnahmeabschnitt 6 sind Auswerte- und/oder Steuereinheiten 7 angeordnet, welche die Auswertung und/oder Steuerung der Motordaten und/oder von Signalen anderer (elektrischer) Funktionselemente übernehmen. Dazu sind die Auswerte- bzw. Steuereinheiten 7 über eine oder mehrere Leitungsverbindungen mit dem Elektromotor 4, weiteren Elektromotoren und/oder weiteren (elektrischen) Funktionseinheiten verbunden. Mittig bzw. zentral auf dem Aufnahmeabschnitt 6 ist ein Schleifringübertrager angeordnet, der einen rotierenden Teil 8a und einen stehenden Teil 8b aufweist.
