Definitions
- the invention relates to a cleaning device for pressure rollers or cylinders by means of a cleaning cloth, which is pressed against the surface to be cleaned and transported from a supply shaft to a collecting shaft for dirty cleaning cloth, with a drive for rotating the collecting shaft comprising a drive cylinder whose piston rod is connected to a pivotable lever which cooperates with a freewheel, which transmits torque during the advancement of the piston, while decoupling the retraction of the piston.
- a cleaning device of this kind is from the DE 10 2004 035 399.9 A1 the applicant known.
- the cleaning cloth which is sprayed with water and / or a cleaning agent, pulled over an elastic strip, in particular rubber strip and pressed by this against the surface of the roller to be cleaned. After some contamination, the cleaning cloth is cyclically pulled from a supply shaft to a collecting shaft and wound up on this.
- the cleaning device is located in an elongated housing with two end plates in which the two ends of the supply shaft and the collecting shaft are mounted. Also, the mentioned elastic strip extends from one end plate to the other.
- an adjusting cylinder As a drive for rotating the winding shaft, an adjusting cylinder is described, the piston rod engages on an outer ring of a freewheel bearing so that the winding shaft is rotated during advancement of the piston rod in the winding direction, while the return stroke stops due to the freewheel effect.
- the GB 2 277 056 A describes a device for cleaning cylinders of a printing machine comprising a cleaning cloth that is of a replaceable Unwinded supply roll and can be wound up on a dirty cloth roll. Described is reversible drive for advancing and partially rewinding the cleaning cloth.
- the drive is an electronically controllable electric motor which drives a gear which is movably mounted so that it can be brought into engagement with either a gear which is connected to the supply roll, or with a toothed wheel which is connected to the dirty cloth roll.
- a device which is designed according to this operating principle works satisfactorily per se.
- the supply of cloth available on the supply shaft is limited so that the cleaning cloth has to be changed from time to time. This leads to business interruptions and thus to loss of time.
- the use of the cleaning cloth is relatively uneconomical. While much dirt accumulates at the beginning of a cleaning process, the dirt load gradually decreases more and more, so that the cleaning cloth is possibly only slightly contaminated.
- the invention has for its object to provide a space-saving and inexpensive to produce cleaning device with which the intervals in which the cleaning cloth must be changed, extended and the utilization of the cleaning cloth can be made more economical overall.
- the freewheel is connected to a drive wheel and that the drive cylinder and the drive wheel are mounted on a pivotally mounted on the device housing holder, which is movable in its pivotal movement between a first position in which a drive connection of the drive wheel for There is a collecting shaft for dirty cleaning cloth, and a second position in which there is a drive connection to the supply shaft.
- the cleaning cloth can therefore be pulled both from the supply shaft to the collecting shaft and vice versa from the collecting shaft back to Supply shaft.
- the cleaning cloth which is only slightly soiled towards the end of a cleaning process, can therefore be used again for cleaning heavily soiled roll surfaces.
- the drive wheel is a gear and on the collecting shaft and the supply shaft are also gears, with which the drive wheel can be alternately engaged. If the direction of rotation of the supply shaft in the return of the tape to be opposite to the direction of rotation of the collecting shaft in the forward, is located between the drive gear and the gear on one of the wool an idler gear.
- the holder, on which the drive cylinder and the drive wheel are located, is preferably formed as a flat plate, which is mounted at one end of the cleaning device.
- a drive for pivoting this plate is preferably a pivot cylinder, in particular air cylinder is provided, which is mounted fixed to the frame on the cleaning device, so that the pivotable plate can be pivoted by means of the pivot cylinder.
- the swivel cylinder for the pivotable holder or plate at the end of a drive operation is in a blocking position, so that it can not be pushed back by the stroke of the drive cylinder. This danger could exist because the drive cylinder is much stronger than the swing cylinder of the pivoting plate.
- a cam roller is otherwise provided, which is connected to a sensor for the winding thickness on the collecting shaft and rests against the other hand, the pivotable lever of the drive.
- This cam roller serves to limit the stroke of the drive cylinder and to adapt the stroke of the drive cylinder to the diameter of the wound web on the collecting shaft, so that with each stroke an equal length piece of the cleaning cloth can be wound.
- the cam roller which causes the stroke limit of the drive cylinder is rotated by the diameter sensor for the winding thickness on the collecting shaft and thus adjusted.
- Fig. 1 In the upper area of the Fig. 1 is the geometric axis of a perpendicular to the plane wave marked, which is hidden in the drawing and which should be referred to here as supply shaft 10.
- the supply shaft 10 serves to receive a supply roll of a clean cleaning cloth. This cleaning cloth is pulled in a manner not shown on an elastic strip and transferred step by step to a collecting shaft, which is also perpendicular to the plane in Fig. 1 is also represented by its geometric axis.
- the collecting shaft 12 is located in the lower region of Fig. 1 ,
- the two shafts 10 and 12 are mounted between two end plates 14, which support and limit the bar-shaped cleaning device on both sides.
- a pivotable plate 22 is mounted, on which some of the in Fig. 1 and 2 shown elements are stored, as will be explained below.
- the pivotable plate 22 is connected to a pivoting cylinder 24 in connection, the piston rod 26 is pivotally connected in an axis 28 with the pivotable plate 22.
- a drive cylinder 30 is pivotally mounted in an axis 32.
- the drive cylinder 30 has a piston rod 34 which is pivotally connected to a lever 36 via an axis 38.
- the lever 36 in turn is connected to an outer ring of a freewheel, not shown, in connection, whose inner ring is connected to a gear 40 in connection, which is mounted in an axis 42 on said pivotable plate 22.
- the freewheel causes 30 torque on the lever 36 and the freewheel on the gear 40 is transmitted during extension of the piston rod 34 of the drive cylinder, on the return stroke of the piston rod 34, however, there is no drive connection, so the gear stops.
- a pivotable pawl 44 is otherwise mounted, which can engage in the gear 40 and lock them. This can prevent the drive running unintentionally.
- the gear 40 may alternatively be engaged with the gear shaft 18 of the collecting shaft (forward drive) or with the gear 16 of the supply shaft (return transport).
- the gear 46 is provided as an intermediate gear, which causes a reversal of direction.
- connection between the piston rod 26 of the swivel cylinder 24 and the pivotable plate is shown here as being released.
- the axis 28 of the piston rod 26 is identical to the axis 52 of the pivotable plate 22, or there is a connection via a coupling joint, as will be described later.
- Fig. 1 shows the position in which the gear 40 is engaged with the gear 18 of the collecting shaft. In this position, the collecting shaft is rotated in the forward direction. It is the usual operation, in which the cleaning cloth is pulled from the supply shaft to the collecting shaft.
- This value is important since it depends on the thickness of the roll how long a portion of the cleaning cloth is that is picked up by a certain rotation of the winding shaft.
- the angle of rotation traveled by the winding shaft 12 at each stroke of the drive cylinder 30 depends on the length of this stroke.
- the stroke length of the piston rod 34 tends to be set the shorter the thicker the winding on the winding shaft.
- the cam roller 56 forms a stop for the pivoting of the lever 36 and thus for the stroke of the cylinder 30th
- Fig. 3 is an enlarged section of Fig. 1 and shows the pivotable plate 22 with the lever 36 and the gear 40 and the gear 18 on the collecting shaft. In this position, there is a risk that the much stronger drive cylinder 30, the relatively weak pivot cylinder 24 of the pivotable plate 22 penetratedrlindt so that it comes, for example, to an undesirable pivoting of the pivotable plate 22 by the drive cylinder 30.
- Fig. 3 shows therefore a joint which connects the piston rod 26 with the pivotable plate 22 and is designated 62.
- the pivotable plate 22 is locked by the hinge 62.
Description
Die Erfindung betrifft eine Reinigungsvorrichtung für Druckwalzen oder -zylinder mit Hilfe eines Reinigungstuches, das gegen die zu reinigende Oberfläche gedrückt und von einer Vorratswelle zu einer Sammelwelle für verschmutztes Reinigungstuch transportiert wird, mit einem Antrieb zum Drehen der Sammelwelle, der einen Antriebszylinder umfasst, dessen Kolbenstange mit einem schwenkbaren Hebel verbunden ist, der mit einem Freilauf zusammenwirkt, der beim Vorschub des Kolbens Drehmoment überträgt, beim Rückzug des Kolbens dagegen entkoppelt.The invention relates to a cleaning device for pressure rollers or cylinders by means of a cleaning cloth, which is pressed against the surface to be cleaned and transported from a supply shaft to a collecting shaft for dirty cleaning cloth, with a drive for rotating the collecting shaft comprising a drive cylinder whose piston rod is connected to a pivotable lever which cooperates with a freewheel, which transmits torque during the advancement of the piston, while decoupling the retraction of the piston.
Eine Reinigungsvorrichtung dieser Art ist aus der
Die
Eine Vorrichtung, die nach diesem Funktionsprinzip ausgebildet ist, arbeitet an sich zufriedenstellend. Naturgemäss ist der auf der Vorratswelle verfügbare Tuchvorrat begrenzt, so dass das Reinigungstuch von Zeit zu Zeit gewechselt werden muss. Dies führt zu Betriebsunterbrechungen und damit zu Zeitverlusten. Im übrigen ist die Ausnutzung des Reinigungstuches verhältnismässig unökonomisch. Während zu Beginn eines Reinigungsvorganges viel Schmutz anfällt, nimmt die Schmutzlast nach und nach immer mehr ab, so dass das Reinigungstuch schliesslich allenfalls noch geringfügig verschmutzt wird.A device which is designed according to this operating principle works satisfactorily per se. Naturally, the supply of cloth available on the supply shaft is limited so that the cleaning cloth has to be changed from time to time. This leads to business interruptions and thus to loss of time. Moreover, the use of the cleaning cloth is relatively uneconomical. While much dirt accumulates at the beginning of a cleaning process, the dirt load gradually decreases more and more, so that the cleaning cloth is possibly only slightly contaminated.
Der Erfindung liegt die Aufgabe zugrunde, eine platzsparende und günstig herzustellende Reinigungsvorrichtung zu schaffen, mit der die Intervalle, in denen das Reinigungstuch gewechselt werden muss, verlängert und die Ausnutzung des Reinigungstuches insgesamt ökonomischer gestaltet werden können.The invention has for its object to provide a space-saving and inexpensive to produce cleaning device with which the intervals in which the cleaning cloth must be changed, extended and the utilization of the cleaning cloth can be made more economical overall.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Freilauf mit einem Antriebsrad verbunden ist und dass der Antriebszylinder und das Antriebsrad auf einer schwenkbar am Vorrichtungsgehäuse gelagerten Halterung angebracht sind, die in ihrer Schwenkbewegung beweglich ist zwischen einer ersten Stellung, in der eine Antriebsverbindung des Antriebsrades zur Sammelwelle für verschmutztes Reinigungstuch besteht, und einer zweiten Stellung, in der eine Antriebsverbindung zur Vorratswelle besteht.This object is achieved in that the freewheel is connected to a drive wheel and that the drive cylinder and the drive wheel are mounted on a pivotally mounted on the device housing holder, which is movable in its pivotal movement between a first position in which a drive connection of the drive wheel for There is a collecting shaft for dirty cleaning cloth, and a second position in which there is a drive connection to the supply shaft.
Das bedeutet, dass die Transportrichtung des Reinigungstuches umgeschaltet werden kann. Das Reinigungstuch kann also sowohl von der Vorratswelle auf die Sammelwelle gezogen werden als auch umgekehrt von der Sammelwelle zurück zur Vorratswelle. Das gegen Ende eines Reinigungsvorgangs nur noch geringfügig verschmutzte Reinigungstuch kann also noch einmal genutzt werden zur Reinigung stark verschmutzter Walzenoberflächen.This means that the transport direction of the cleaning cloth can be switched. The cleaning cloth can therefore be pulled both from the supply shaft to the collecting shaft and vice versa from the collecting shaft back to Supply shaft. The cleaning cloth, which is only slightly soiled towards the end of a cleaning process, can therefore be used again for cleaning heavily soiled roll surfaces.
Vorzugsweise ist das Antriebsrad ein Zahnrad und auf der Sammelwelle sowie der Vorratswelle befinden sich ebenfalls Zahnräder, mit denen das Antriebsrad abwechselnd in Eingriff gebracht werden kann. Wenn die Drehrichtung der Vorratswelle beim Rücklauf des Bandes entgegengesetzt zu der Drehrichtung der Sammelwelle beim Vorlauf sein soll, befindet sich zwischen dem Antriebs-Zahnrad und dem Zahnrad auf einer der Wollen ein Zwischenzahnrad.Preferably, the drive wheel is a gear and on the collecting shaft and the supply shaft are also gears, with which the drive wheel can be alternately engaged. If the direction of rotation of the supply shaft in the return of the tape to be opposite to the direction of rotation of the collecting shaft in the forward, is located between the drive gear and the gear on one of the wool an idler gear.
Die Halterung, auf der sich der Antriebszylinder und das Antriebsrad befinden, ist vorzugsweise als flache Platte ausgebildet, die an einem Ende der Reinigungsvorrichtung gelagert ist. Als Antrieb zum Schwenken dieser Platte ist vorzugsweise ein Schwenkzylinder, insbesondere Luftzylinder vorgesehen, der gestellfest an der Reinigungsvorrichtung gelagert ist, so dass die schwenkbare Platte mit Hilfe des Schwenkzylinders geschwenkt werden kann.The holder, on which the drive cylinder and the drive wheel are located, is preferably formed as a flat plate, which is mounted at one end of the cleaning device. As a drive for pivoting this plate is preferably a pivot cylinder, in particular air cylinder is provided, which is mounted fixed to the frame on the cleaning device, so that the pivotable plate can be pivoted by means of the pivot cylinder.
Vorzugsweise geht der Schwenkzylinder für die schwenkbare Halterung bzw. Platte am Ende eines Antriebsvorganges in eine Sperrstellung, so dass er nicht durch den Hub des Antriebszylinders zurückgedrückt werden kann. Diese Gefahr könnte deshalb bestehen, weil der Antriebszylinder wesentlich stärker ist als der Schwenkzylinder der schwenkbaren Platte.Preferably, the swivel cylinder for the pivotable holder or plate at the end of a drive operation is in a blocking position, so that it can not be pushed back by the stroke of the drive cylinder. This danger could exist because the drive cylinder is much stronger than the swing cylinder of the pivoting plate.
Auf der schwenkbaren Platte ist im übrigen eine Kurvenrolle vorgesehen, die zum einen mit einem Fühler für die Wickeldicke auf der Sammelwelle verbunden ist und zum anderen gegen den schwenkbaren Hebel des Antriebs anliegt. Diese Kurvenrolle dient zur Hubbegrenzung des Antriebszylinders und zur Anpassung des Hubes des Antriebszylinders an den Durchmesser der aufgewickelten Bahn auf der Sammelwelle, so dass mit jedem Hub ein gleich langes Stück des Reinigungstuches aufgewickelt werden kann.On the pivotable plate, a cam roller is otherwise provided, which is connected to a sensor for the winding thickness on the collecting shaft and rests against the other hand, the pivotable lever of the drive. This cam roller serves to limit the stroke of the drive cylinder and to adapt the stroke of the drive cylinder to the diameter of the wound web on the collecting shaft, so that with each stroke an equal length piece of the cleaning cloth can be wound.
Die Kurvenrolle, die die Hubbegrenzung des Antriebszylinders bewirkt, wird durch den Durchmesserfühler für die Wickeldicke auf der Sammelwelle gedreht und damit eingestellt.The cam roller which causes the stroke limit of the drive cylinder is rotated by the diameter sensor for the winding thickness on the collecting shaft and thus adjusted.

Alle in der Zeichnung dargestellten Elemente, die nicht auf der schwenkbaren Platte 22 gelagert sind, sind auf der mit 14 bezeichneten Endplatte des Gehäuses befestigt oder gelagert, die das nicht dargestellte Gehäuse der Reinigungsvorrichtung abschließt. Dies gilt insbesondere für die beiden Wellen 10 und 12 mit ihren Zahnrädern 16 und 18, die schwenkbare Platte 22 selbst mit ihrem Schwenkzylinder 24, das Zwischenzahnrad 46, und eine Kurvenrolle 56, die in einer Achse 58 drehbar auf der Endplatte 14 gelagert ist. Die Kurvenrolle 56 kann durch einen schwenkbaren Fühler 60 in ihrer Winkelposition eingestellt werden, der hinter der Endplatte 14 liegt und daher nur gestrichelt dargestellt ist. Der Fühler dient dazu, die Dicke des aufgenommenen Wickels des verschmutzten Reinigungstuchs auf der Sammelwelle 12 abzutasten.All elements shown in the drawing, which are not mounted on the
