Abstract

In a papermaking factory a large roll of paper is transported between winding and unwinding stations on a rail (5) mounted rolling (3, 4) chassis (2). The large paper roll rests on a spindle (7) supported at each end in a cradle (6, 7). The chassis (2) incorporates a chassis-turning device (9) that rotates the chassis on the rails with respect to a vertical axis (16). The chassis-turning device (9) incorporates a jack resting on a pressure plate which raises the chassis from the rails (5). The plate spans the full width of track between the wheels.

Description

Die Erfindung betrifft einen Tambourwagen mit einem Chassis, das Räder, die auf einer Fahrbahn aufstehen, und eine Tambouraufnahme aufweist. Ferner betrifft die Erfindung ein Verfahren zum Ändern der Abwickel-Lage einer auf einem ein Chassis aufweisenden Tambourwagen abgelegten Jumbo-Rolle.The invention relates to a spool truck with a chassis, the wheels that stand up on a roadway, and a Tambouraufnahme has. Furthermore, the invention relates to a method for changing the unwinding position of a jumbo roll deposited on a chassis having a spool truck.

Die Erfindung wird im folgenden in Verbindung mit der Herstellung einer Papierbahn beschrieben. Sie ist aber auch bei anderen Materialbahnen anwendbar, die auf ähnliche Weise gehandhabt werden, beispielsweise Kartonbahnen.The invention will be described below in connection with the production of a paper web. But it is also applicable to other webs that are handled in a similar manner, such as cardboard sheets.

Papierbahnen werden in der Regel endlos produziert. Eine durchgehende Herstellung, bei der die Papierbahn von der Papiermaschine bis zu einem Rollenschneider durchläuft, wo sie zu verkaufsfertigen Rollen aufgewickelt wird, ist jedoch in den meisten Papierfabriken noch nicht möglich. Die Papierbahn wird daher vielfach zwischen einzelnen Bearbeitungsschritten aufgewickelt. Hierzu verwendet man relativ stabile Wickelkerne, sogenannte Tamboure. Die darauf gebildeten Papierrollen werden auch als Jumbo-Rollen bezeichnet. Jumbo-Rollen haben bei entsprechenden Breiten der Papierbahn, die bis zu 10 m betragen kann, ein relativ großes Gewicht, das durchaus eine Größenordnung von über 100 Tonnen erreichen kann.Paper webs are usually produced endlessly. Continuous production, however, in which the paper web passes from the paper machine to a slitter where it is wound into ready-to-roll rolls, is still present in most paper mills not possible. The paper web is therefore often wound up between individual processing steps. For this one uses relatively stable hubs, so-called Tamboure. The paper rolls formed thereon are also called jumbo rolls. Jumbo rolls have a relatively large weight at appropriate widths of the paper web, which can be up to 10 m, which can well reach a magnitude of over 100 tons.

Zum Transport der Jumbo-Rollen in der Halle einer Papierfabrik'verwendet man unter anderem Tambourwagen. Diese Tambourwagen haben eine Tambouraufnahme, in der die Jumbo-Rolle abgelegt werden kann. Mit Hilfe des Tambourwagens kann eine Jumbo-Rolle beispielsweise von einer Aufwickelstation einer Papiermaschine zu einer Abwickelstation eines Kalanders verfahren werden.For transporting the jumbo rolls in the hall of a paper mill, one uses, among other things, drum wagons. These spools have a reel seat in which the jumbo roll can be stored. With the aid of the spool truck, a jumbo roll can be moved, for example, from a winding station of a paper machine to an unwinding station of a calender.

Hierbei tritt gelegentlich das Problem auf, daß die Aufwickelrichtung der Jumbo-Rolle nicht mit der gewünschten Abwickelrichtung in der zu versorgenden Bearbeitungseinrichtung übereinstimmt. In diesem Fall muß die Jumbo-Rolle mit einem Hallenkran angehoben und um 180° gedreht werden. In einer alternativen Vorgehensweise muß man den Tambourwagen in einer Schleife fahren, so daß am Ende dieses Fahrweges die Jumbo-Rolle in die gewünschte Lage gebracht worden ist. Ähnliche Probleme gelten dann, wenn die Laufrichtung der Papierbahn geändert werden muß, beispielsweise um 90°. In diesem Fall muß der Tambourwagen eine entsprechende Kurve fahren können, was nicht immer problemlos möglich ist.Occasionally, the problem arises that the winding direction of the jumbo roll does not match the desired unwinding direction in the processing device to be supplied. In this case, the jumbo roll must be lifted with a hall crane and rotated by 180 °. In an alternative approach you have to drive the spool truck in a loop, so that at the end of this driveway, the jumbo roll has been brought into the desired position. Similar problems apply when the direction of the paper web must be changed, for example by 90 °. In this case, the Tambourwagen must be able to drive a corresponding curve, which is not always easily possible.

DE 26 31 355 A1 zeigt eine fahrbare Transportbühne für die Beschickung von Rollenträgern an Rotations-Druckmaschinen. Die Transportbühne ist dabei mit mehreren am äußeren Umfang angeordneten Stützrollen und einem Drehzapfen um einen kleinen Winkel drehbar in einem Bühnenrahmen gelagert, der wiederum mit Laufrollen ausgerüstet ist und auf Schienen verfahren werden kann. Damit möchte man die Papierrolle, die auf der Transportbühne gelagert ist, so ausrichten können, daß sie von den Rollenträgern erfaßt werden kann.DE 26 31 355 A1 shows a mobile transport platform for the loading of roller carriers on rotary printing machines. The transport platform is mounted with several arranged on the outer circumference support rollers and a pivot about a small angle rotatably mounted in a stage frame, which in turn is equipped with rollers and can be moved on rails. This would like to align the paper roll, which is mounted on the transport platform, so that it can be detected by the roller carriers.

JP 07 242 356 A zeigt ein Fahrzeug zum Transportieren einer Papierrolle und ein Verfahren zum Zuführen einer Papierrolle. Das Fahrzeug weist eine Tragfläche auf, die mit zwei um 90° zueinander versetzten Aufnahmen für die Papierrolle versehen ist.JP 07 242 356 A shows a vehicle for transporting a paper roll and a method for feeding a paper roll. The vehicle has a support surface which is provided with two mutually offset by 90 ° receptacles for the paper roll.

Der Erfindung liegt die Aufgabe zugrunde, auf einfache Weise die Abwickelrichtung einer Jumbo-Rolle ändern zu können.The invention has for its object to be able to change the unwinding of a jumbo roll in a simple manner.

Diese Aufgabe wird bei einem Tambourwagen der eingangs genannten Art gelöst durch eine am Chassis angeordnete Drehvorrichtung, die eine Hubeinrichtung aufweist, mit der das Chassis vom Fußboden abhebbar ist und mit der das Chassis gegenüber der Fahrbahn um eine vertikale Achse drehbar ist.This object is achieved in a spool truck of the type mentioned by a arranged on the chassis rotating device having a lifting device with which the chassis is lifted from the floor and with which the chassis relative to the roadway about a vertical axis is rotatable.

Mit einem derartigen Tambourwagen ist es nicht länger erforderlich, die Jumbo-Rolle mit Hilfe eines Hallenkranes vom Tambourwagen abzuheben und zu drehen. Die Jumbo-Rolle kann vielmehr auf dem Tambourwagen verbleiben. Der Tambourwagen weist selbst eine Drehvorrichtung auf, die so ausgebildet ist, daß sie das Chassis gegenüber der Fahrbahn verdrehen kann. Die Fahrbahn kann einfach der Fußboden der Halle sein. In der Regel ist jedoch die Fahrbahn als Schienenpaar ausgebildet. In diesem Fall wird das Chassis gegenüber der Fahrbahn so gedreht, daß es beispielsweise um 180° versetzt wieder auf den Schienen aufgesetzt werden kann. Die Hubeinrichtung muß zwar ein relativ großes Gewicht anheben können, nämlich das Gewicht der Jumbo-Rolle und zusätzlich das Gewicht des Tambourwagens. Dafür wird aber der Drehvorgang deutlich vereinfacht. Man muß nicht mehr die Reibung der Räder auf der Fahrbahn oder dem Untergrund überwinden.With such a spool truck, it is no longer necessary to lift the jumbo roll with the help of a hall crane from the spool truck and turn. The jumbo roll can rather remain on the spool cart. The spool truck itself has a turning device which is designed so that it can rotate the chassis relative to the roadway. The roadway can simply be the floor of the hall. As a rule, however, the roadway is designed as a pair of rails. In this case, the chassis is rotated relative to the road so that it can be placed back on the rails, for example offset by 180 °. Although the lifting device must be able to raise a relatively large weight, namely, the weight of the jumbo roll and additionally the weight of the Tambourwagens. But the turning process is significantly simplified. You no longer have to overcome the friction of the wheels on the road or the ground.

Bevorzugterweise weist die Hubeinrichtung eine Druckplatte auf, die auf einen Fußboden aufsetzbar ist. Die Druckplatte leitet die entstehenden Gewichtskräfte über einen größeren Bereich in den Fußboden ab. Eine Beschädigung des Fußbodens ist damit nahezu ausgeschlossen. Darüber hinaus bekommt die Hubeinrichtung durch die Druckplatte eine erhöhte Stabilität. Es besteht also praktisch keine Gefahr, daß der Tambourwagen bei der Drehung um seine vertikale Achse kippt.Preferably, the lifting device has a pressure plate which can be placed on a floor. The pressure plate derives the resulting weight forces over a larger area in the floor. Damage to the floor is thus almost impossible. In addition, the lifting device gets through the pressure plate increased stability. Thus, there is virtually no danger that the spool truck tilts during rotation about its vertical axis.

Vorzugsweise weist die Druckplatte eine Breite auf, die dem seitlichen Abstand der Räder entspricht. Dies ist vor allem dann von Vorteil, wenn die Fahrbahn als Schienenpaar ausgebildet ist. In diesem Fall paßt die Druckplatte genau zwischen die Schienen. Die Schienen bilden dann eine Drehmomentstütze für die Druckplatte, so daß die beim Drehen auftretenden Beschleunigungs- und Bremskräfte optimal abgeleitet werden können.Preferably, the pressure plate has a width which corresponds to the lateral spacing of the wheels. This is especially advantageous if the roadway is designed as a pair of rails. In this case, the pressure plate fits exactly between the rails. The rails then form a torque support for the pressure plate, so that the acceleration and braking forces occurring during rotation can be optimally dissipated.

Hierbei ist bevorzugt, daß die Druckplatte in Verlängerung eines Rades auf mindestens einer Seite eine Eingriffsgeometrie zu der Fahrbahn aufweist. Man muß sich dann nicht mehr darauf beschränken, daß die Druckplatte zwischen die Schienen paßt. Unter ungünstigen Bedingungen könnte dies dazu führen, daß die Druckplatte, die in der Regel rechteckförmig ausgebildet ist, beim Verdrehen die Schienen spreizt. Dies gilt beispielsweise dann, wenn die Diagonale der Druckplatte größer ist als der Abstand zwischen den Schienen. Wenn man eine Eingriffsgeometrie vorsieht, dann wird die Druckplatte mit Hilfe der Eingriffsgeometrie nicht nur gegen Verdrehen gesichert. Die Druckplatte hält die Schienen auch fest, so daß die Gefahr einer Beschädigung nicht besteht.It is preferred that the pressure plate in extension of a wheel on at least one side has an engagement geometry to the roadway. One then no longer has to confine himself to the fact that the pressure plate fits between the rails. Under unfavorable conditions, this could cause the pressure plate, which is generally rectangular in shape, spreads the rails during rotation. This applies, for example, when the diagonal of the pressure plate is greater than the distance between the rails. If you provide an engagement geometry, then the pressure plate is not only secured against rotation by means of the engagement geometry. The pressure plate also holds the rails so that the risk of damage does not exist.

Vorzugsweise weist die Hubeinrichtung einen Drehkranz mit einem Drehantrieb auf. Die Hubeinrichtung stützt sich also auf einer Unterlage ab, die über den Drehkranz auf der Druckplatte abgestützt ist. Die einzelnen Bewegungen des Chassis des Tambourwagens werden also voneinander entkoppelt.Preferably, the lifting device on a turntable with a rotary drive. The lifting device is thus supported on a base, which is supported on the turntable on the pressure plate. The individual movements of the chassis of the Tambourwagens are thus decoupled from each other.

Bevorzugterweise ist eine mitfahrende Leitungstrommel vorgesehen, auf die eine elektrische Versorgungsleitung aufgewickelt ist. Damit ist eine elektrische Energiezufuhr möglich. Die Versorgungsleitung kann an einem Ende fest mit einem Einspeisepunkt verbunden sein. Das andere Ende ist beweglich, so daß der Tambourwagen nicht nur relativ freizügig verfahren werden kann, sondern auch an anderen Stellen der Ausrichtung der Jumbo-Rolle ändern kann.Preferably, a traveling cable drum is provided, on which an electrical supply line is wound. This is an electrical power supply possible. The supply line may be fixedly connected to an entry point at one end. The other end is movable, so that the spool truck can not only be moved relatively freely, but also at other locations the orientation of the jumbo roll can change.

Vorzugsweise weist der Fußboden einer Kabelrinne auf. In diese Kabelrinne kann die Versorgungsleitung abgelegt werden, wenn der Tambourwagen verfahren wird. Wenn dann die Druckplatte auf den Fußboden aufgesetzt wird, dann wird die Versorgungsleitung auch bei größeren Kräften nicht beschädigt, weil sie geschützt in der Kabelrinne liegt.Preferably, the floor of a cable tray. In this cable tray, the supply line can be stored when the drum is moved. Then, when the pressure plate is placed on the floor, then the supply line is not damaged even with larger forces, because it is protected in the cable tray.

Vorzugsweise ist an mindestens einer Drehposition eine elektrische Verbindung zwischen der Versorgungsleitung und einer Versorgungsstation vorgesehen. Wenn nur eine Drehposition für den Tambourwagen vorgesehen ist, dann befindet sich idealerweise dort die elektrische Versorgung.Preferably, an electrical connection between the supply line and a supply station is provided at at least one rotational position. If only one rotational position is provided for the spool truck, then ideally there is the electrical supply.

Auch ist von Vorteil, daß Sensoren vorgesehen sind, die den Drehbereich des Chassis und/oder den Fahrweg überwachen. Dies ist eine Sicherheitsmaßnahme. Der Tambourwagen kann dann ferngesteuert oder automatisch nicht nur verfahren, sondern auch gedreht werden.It is also advantageous that sensors are provided which monitor the range of rotation of the chassis and / or the track. This is a security measure. The spool truck can then be remotely controlled or automatically not only moved, but also rotated.

Die Aufgabe wird bei einem Verfahren der eingangs genannten Art dadurch gelöst, daß der Tambourwagen mit seinem Chassis durch eine am Chassis angeordnete Drehvorrichtung um eine vertikale Achse verdreht wird und der Tambourwagen vor dem Verdrehen angehobene wird.The object is achieved in a method of the type mentioned above in that the spool truck is rotated with its chassis by a arranged on the chassis rotating device about a vertical axis and the spool truck is raised before twisting.

Wenn der Tambourwagen um eine vertikale Achse verdreht wird, dann wird die Jumbo-Rolle mitgedreht. Sie kann damit problemlos ihre Ausrichtung und damit ihre Wikkelrichtung ändern. Das Anheben ist eine einfache Maßnahme, um das Verdrehen zu erleichtern. Ein angehobener Tambourwagen kann einfach um seine vertikale Achse gedreht werden, ohne daß Teile von ihm auf dem Fußboden oder auf dem Fahrweg schleifen.If the drum is rotated about a vertical axis, then the jumbo roll is rotated. It can easily change their orientation and thus their Wikkelrichtung. Lifting is a simple measure to facilitate twisting. A raised spool truck can simply be rotated around its vertical axis without any parts of it dragging on the floor or on the track.

Vorzugsweise verwendet man eine Drehvorrichtung, die sich zwischen Schienen abstützt, auf denen der Tambourwagen verfahren wird. Die Schienen bilden dann eine Drehmomentstütze, so daß beim Drehen auftretende Beschleunigungs- und Bremskräfte auch bei größeren Gewichten der Jumbo-Rolle aufgefangen werden können.Preferably, a rotating device is used, which is supported between rails on which the spool truck is moved. The rails then form a torque arm, so that acceleration and braking forces occurring during turning can be absorbed even with larger weights of the jumbo roll.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher beschrieben. Hierin zeigen:

The roadway is, as can be seen from Fig. 2, formed by two parallel rails 5a, 5b, which are placed on a floor 5 or embedded in it.

An der Oberseite des Chassis ist eine Tambouraufnahme 6 angeordnet, in die ein Tambour 7 eingelegt ist, auf dem eine Jumbo-Rolle aufgewickelt ist. Die Darstellung der Jumbo-Rolle 8 ist hier nicht maßstäblich. Die Jumbo-Rolle kann durchaus eine Länge von bis zu 10 m und einen Durchmesser von über 3 m aufweisen. Ihr Gewicht beträgt mehrere Tonnen. Große Jumbo-Rollen 8 können durchaus ein Gewicht von über 100 Tonnen aufweisen.At the top of the chassis, a spool receptacle 6 is arranged, in which a spool 7 is inserted, on which a jumbo roll is wound up. The representation of the jumbo roll 8 is not to scale here. The jumbo roll may well have a length of up to 10 m and a diameter of over 3 m. Their weight is several tons. Large jumbo rolls 8 can have a weight of more than 100 tons.

Auf die Jumbo-Rolle 8 ist eine Materialbahn, beispielsweise eine Papierbahn, aufgewickelt. Diese Aufwicklung ist in einer bestimmten Richtung erfolgt. Beispielsweise kann die Jumbo-Rolle 8 eine Wickelrichtung aufweisen, bei der die Materialbahn von oben aus der Sicht des Betrachters kommend auf die Jumbo-Rolle 8 aufgewikkelt worden ist. Wenn die Materialbahn nun in die entgegengesetzte Richtung abgewickelt werden soll, beispielsweise von oben, aber in die Zeichenebene hinein (bezogen auf die Darstellung der Fig. 1), dann ist ein Umsetzen der Jumbo-Rolle 8 erforderlich. Dies wurde bislang mit Hilfe eines Hallenkranes durchgeführt, der die Jumbo-Rolle 8 vom Tambourwagen 1 abgehoben hat. Ein Arbeiter hat die Rolle dann gedreht und nach dem Auspendeln konnte die Jumbo-Rolle 8 wieder auf den Tambourwagen 1 aufgesetzt werden. Eine alternative Vorgehensweise bestand darin, die Fahrbahn 5a, 5b des Tambourwagens in einer Schleife zu führen, so daß der Tambourwagen 1 nach dem Durchfahren dieser Schleife um 180° gedreht war. Dies bedeutete jedoch einen teilweise erheblichen Raumbedarf, weil ein minimaler Kurvenradius nicht unterschritten werden dürfte.On the jumbo roll 8, a material web, such as a paper web, wound up. This winding has been done in a certain direction. For example, the jumbo roll 8 may have a winding direction in which the material web has been wound onto the jumbo roll 8 coming from above, as seen by the observer. If the material web is now to be unwound in the opposite direction, for example from above, but into the plane of the drawing (with reference to the representation of FIG. 1), it is necessary to convert the jumbo roll 8. That was previously carried out with the help of a hall crane, which has lifted the jumbo roll 8 from the spool truck 1. A worker has then turned the roller and after swinging out the jumbo roller 8 could be put back on the spool truck 1. An alternative approach was to run the carriageway 5a, 5b of the drum wagon in a loop, so that the spool truck 1 was rotated by 180 ° after passing through this loop. However, this meant a partially considerable space requirement, because a minimum radius of curvature should not be undershot.

Um dieses Problem zu entschärfen, weist der in Fig. 1 dargestellte Tambourwagen 1 eine Drehvorrichtung 9 auf, die in weiteren Einzelheiten in Fig. 2 dargestellt ist.To alleviate this problem, the sprocket truck 1 shown in FIG. 1 has a rotating device 9, which is shown in more detail in FIG.

Die Drehvorrichtung weist zunächst eine Druckplatte 10 auf. Die Druckplatte 10 hat parallel zu den Schienen 5a, 5b jeweils eine Eingriffsgeometrie 11a, 11b, mit der sie mit den Schienen 5a, 5b in Eingriff gebracht werden kann. Die Druckplatte 10 befindet sich vorzugsweise zwischen den Rädern 3, 4, die aber in der Darstellung der Fig. 2 aus Gründen der Übersicht weggelassen worden sind. Die Druckplatte 10 wird während eines Verfahrens des Tambourwagens in einem gewissen kleinen Abstand zu den Schienen 5a, 5b und zum Fußboden 5 gehalten, so daß die Druckplatte 10 ein Verfahren des Tambourwagens 1 nicht behindert.The rotating device initially has a pressure plate 10. The pressure plate 10 has parallel to the rails 5a, 5b respectively an engagement geometry 11a, 11b, with which they can be brought into engagement with the rails 5a, 5b. The pressure plate 10 is preferably located between the wheels 3, 4, but have been omitted in the illustration of FIG. 2 for reasons of clarity. The pressure plate 10 is held during a process of the Tambourwagens at a certain small distance from the rails 5a, 5b and the floor 5, so that the pressure plate 10 does not hinder a process of the Tambourwagens 1.

Auf der Druckplatte 10 ist ein Drehkranz 17 angeordnet, der drehbar eine Lagerplatte 12 abstützt. Ein Drehantrieb 13 ist vorgesehen, um die Lagerplatte 12 gegenüber der Druckplatte 10 zu verdrehen. Der Drehantrieb 13 hat beispielsweise ein Ritzel 14 oder ein Reibrad, das mit dem Drehkranz 11 in Eingriff steht.On the pressure plate 10, a turntable 17 is arranged, which rotatably supports a bearing plate 12. A rotary drive 13 is provided to rotate the bearing plate 12 relative to the pressure plate 10. The rotary drive 13 has, for example, a pinion 14 or a friction wheel, which is in engagement with the turntable 11.

Auf der Lagerplatte 12 ist eine Hubeinrichtung 15 vorgesehen, die sich mit ihrem oberen Ende am Chassis 2 des Tambourwagens 1 abstützt. Die Hubeinrichtung 15 kann auf vielerlei Weise ausgebildet sein. Sie kann beispielsweise durch hydraulische Kolben-ZylinderAnordnungen gebildet sein. Es ist aber auch möglich, einen Spindelantrieb zu verwenden, der elektrisch betätigt wird, oder ein Druckkissen, das mit Luft gefüllt werden kann.On the bearing plate 12, a lifting device 15 is provided, which is supported with its upper end on the chassis 2 of the Tambourwagens 1. The lifting device 15 can be designed in many ways. It can be formed for example by hydraulic piston-cylinder arrangements. But it is also possible to use a spindle drive, which is electrically operated, or a pressure pad that can be filled with air.

Wenn nun die Ausrichtung der Jumbo-Rolle 8 verändert werden soll, dann wird der Tambourwagen 1 in eine Position verfahren, in der er um seine vertikale oder Hochachse 16 verdreht werden kann. Die Hubeinrichtung 15 wird in Betrieb gesetzt und senkt zunächst die Druckplatte 10 so ab, daß die Eingriffsgeometrien 11a, 11b der Druckplatte 10 in Eingriff mit den Schienen 5a, 5b kommen. Bei der Fortsetzung der Betätigung der Hubeinrichtung 15 wird das Chassis 2 dann soweit angehoben, daß die Räder 3, 4 von den Schienen 5a, 5b frei kommen. Dies ist in der Regel bereits nach wenigen Zentimetern Hub der Fall.If now the orientation of the jumbo roll 8 to be changed, then the spool truck 1 is moved to a position in which it can be rotated about its vertical or vertical axis 16. The lifting device 15 is put into operation and first lowers the pressure plate 10 so that the engagement geometries 11a, 11b of the pressure plate 10 come into engagement with the rails 5a, 5b. In the continuation of the operation of the lifting device 15, the chassis 2 is then raised so far that the wheels 3, 4 come free from the rails 5a, 5b. This is usually the case after only a few centimeters of stroke.

Sobald das Chassis 2 in ausreichendem Maße angehoben worden ist, wird der Drehantrieb 13 betätigt. Dieser dreht nun die Lagerplatte 12 gegenüber der Druckplatte 10 und damit das auf der Hubeinrichtung 15 abgestützte Chassis 2. Wenn dann das Chassis 2 um beispielsweise 180° gedreht worden ist, dann wird das Chassis 2 mit Hilfe der Hubeinrichtung 15 wieder abgesenkt, so daß die Räder 3, 4 wieder auf den Schienen 5a, 5b aufstehen. Damit ist die Wickelrichtung der Jumbo-Rolle 8 gegenüber Behandlungsstationen, in denen die auf der Jumbo-Rolle 8 aufgewickelte Bahn behandelt werden soll, geändert worden.Once the chassis 2 has been sufficiently raised, the rotary actuator 13 is actuated. This now rotates the bearing plate 12 relative to the pressure plate 10 and thus supported on the lifting device 15 chassis 2. If then the chassis 2 has been rotated by 180 °, for example, then the chassis 2 is lowered by means of the lifting device 15 again, so that the wheels 3, 4 rise again on the rails 5a, 5b. Thus, the winding direction of the jumbo roll 8 has been changed from treatment stations in which the web wound on the jumbo roll 8 is to be treated.

Das Chassis 2 weist Sensoren 18, 19 auf, die das "Umfeld" des Tambourwagens 1 überwachen und eine Bewegung stoppen, sobald sich ein Gegenstand oder eine Person im Bewegungsbereich des Tambourwagens 1 befindet. Dies gilt auch für die oben geschilderte Drehbewegung.The chassis 2 has sensors 18, 19 which monitor the "environment" of the drum-type vehicle 1 and stop movement as soon as an object or a person is in the range of motion of the drum-type vehicle 1. This also applies to the above-described rotational movement.

Der Tambourwagen 1 weist eine mitfahrende Leitungstrommel 20 auf, auf die eine elektrische Versorgungsleitung 21 aufgewickelt ist. Wenn der Tambourwagen 1 verfahren wird, dann wickelt sich die Versorgungsleitung 21 von der Leitungstrommel 20 ab oder wird auf die Leitungstrommel 20 aufgewickelt. Die Leitungstrommel 20 kann hierzu beispielsweise eine Federvorspannung oder einen Motor (nicht dargestellt) aufweisen.The spool truck 1 has a traveling cable drum 20, on which an electrical supply line 21 is wound. When the spool truck 1 is moved, the supply line 21 unwinds from the reel drum 20 or is wound on the reel drum 20. For this purpose, the line drum 20 can, for example, have a spring preload or a motor (not shown).

Die Versorgungsleitung 21 ist mit einem Einspeisepunkt 22 verbunden, beispielsweise einer Steckdose. Es ist allerdings von Vorteil, wenn der Einspeisepunkt 22 einen drehbaren Anschluß aufweist, so daß es im Grunde keine Rolle spielt, ob sich der Tambourwagen 1 in die eine oder in die andere Richtung von dem Einspeisepunkt 22 entfernt. Die Versorgungsleitung 21 ist auf dem Tambourwagen durch ein Rollenpaar 23 geführt, so daß sich immer eine definierte Ausgangslage für die Versorgungsleitung ergibt.The supply line 21 is connected to a feed point 22, for example a socket. However, it is advantageous if the feed point 22 has a rotatable connection, so that it basically does not matter whether the drum carriage 1 in one or the other direction away from the feed point 22. The supply line 21 is guided on the spool by a pair of rollers 23, so that there is always a defined starting position for the supply line.

Wie aus Fig. 2 zu erkennen ist, weist der Fußboden 5 eine Kabelrinne 24 auf, in die die Versorgungsleitung 21 eingelegt wird, wenn sich der Tambourwagen bewegt. Durch die Kabelrinne 24 steht ein Raum zur Verfügung, in dem die Versorgungsleitung 21 geschützt liegt und deswegen auch nicht beschädigt werden kann, wenn die Druckplatte 10 auf dem Fußboden 5 abgelegt wird und beim nachfolgenden Anheben des Chassis mit aufgelegter Jumbo-Rolle 8 erhebliche Kräfte zwischen der Druckplatte 10 und dem Fußboden 5 wirken.As can be seen from Fig. 2, the floor 5 has a cable tray 24, in which the supply line 21 is inserted when the drum moves. Through the cable tray 24 is a space available in which the supply line 21 is protected and therefore can not be damaged if the pressure plate 10 is placed on the floor 5 and the subsequent lifting of the chassis with the jumbo roller 8 considerable forces between the pressure plate 10 and the floor 5 act.
