Description

Die Erfindung betrifft eine Wasch-, Trocknungs- oder Polierwalze für Fahrzeugwasch- und/oder -polieranlagen, mit mehreren auf einem rotierend antreibbaren Walzenkern in axialem Abstand voneinander in Radialebenen zur Walzenachse angeordneten Tragscheiben und mit einer Vielzahl von im wesentlichen radial vom Umfang der Scheiben abstehenden, streifenförmigen Arbeitselementen aus Filz, Vlies, Kunstleder, Leder, fellartigem Material oder dgl., deren Arbeitsflächen sich im wesentlichen parallel zur Walzenachse erstrecken und deren radial innere Befestigungsenden jeweils mit einer der Tragscheiben verbunden sind.The invention relates to a washing, drying or Polishing roller for vehicle washing and / or polishing systems, with several on a rotating driven core at an axial distance from one another in radial planes to the roller axis arranged support disks and with a variety of radially projecting from the periphery of the disks, strip-shaped working elements made of felt, Fleece, synthetic leather, leather, fur-like material or Like. whose work surfaces are essentially parallel extend to the roller axis and its radially inner Fastening ends with one of the support washers are connected.

Bei einer derartigen bekannten Walze zum Waschen von Fahrzeugen (DE 295 09 406 U1) sind die Arbeitselemente jeweils an ihren Befestigungsenden in Längsrichtung des Arbeitselements gefaltet und die durch den Einschnitt im Befestigungsende gebildeten Endabschnitte liegen vollflächig an der Tragscheibe an und sind an diese angenäht. Das Annähen hat den Nachteil, daß die Arbeitselemente bei Verschleiß nicht einzeln ausgetauscht werden können. Es muß vielmehr die gesamte Walze aus der Fahrzeugwaschanlage ausgebaut und dann zerlegt werden, um die Tragscheiben nach und nach vom Walzenkern abziehen zu können und durch Tragscheiben mit neuen Arbeitselementen zu ersetzen. Weiterhin werden die Arbeitselemente durch die Faltung ihres Befestigungsendes an diesen versteift, wobei die Versteifung je nach Drehrichtung der Walze unterschiedlich ist. Dies hat zur Folge, daß die Waschwalze je nach Drehrichtung ein unterschiedliches Drehmoment erfordert, was zu Steuerungsproblemen führen kann. Es gibt Wasch-, Trocknungs- oder Polierwalzen, bei denen die Tragscheiben gegenüber dem Walzenkern drehbar sind und zwischen den Tragscheiben Stützelemente mit radial abstehenden Borsten angeordnet sind. Diese Stützelemente sind mit dem Walzenkern drehfest verbunden (vgl. DE 295 18 089 U1). Bei diesen Walzen erfolgt die Drehmitnahme der Arbeitselemente hauptsächlich dadurch, daß die Borsten am radial inneren Ende der Arbeitselemente anliegen. Wenn jedoch das radial innere Ende, wie es zuerst beschrieben wurde, flächig an der Tragescheibe anliegt, dann ist keine genau definierte Drehmitnahme der Arbeitselemente gewährleistet.In such a known roller for washing Vehicles (DE 295 09 406 U1) are the working elements in each case at their fastening ends in the longitudinal direction of the working element folded and that through the incision end portions formed in the fastening end are in full contact with the support disc and are on these sewn on. Sewing has the disadvantage that the Work elements are not replaced individually when worn can be. Rather, it must be the entire Roller removed from the car wash and then be dismantled to gradually remove the support disks from To be able to pull off the roller core and through support disks to be replaced with new work elements. Farther are the working elements by folding their End of attachment to this stiffened, the stiffening depending on the direction of rotation of the roller is. This has the consequence that the washing roller ever a different torque depending on the direction of rotation requires, which can lead to control problems. There are washing, drying or polishing rollers, at which the support disks opposite the roller core are rotatable and between the support disks support elements are arranged with radially projecting bristles. This Support elements are non-rotatably connected to the roller core (see DE 295 18 089 U1). With these rollers, the Rotational entrainment of the work elements mainly through that the bristles at the radially inner end of the working elements issue. However, if the radially inner end, as it was first described, flat on the support disc is present, then there is no precisely defined rotary drive of the working elements guaranteed.

Der Erfindung liegt damit die Aufgabe zugrunde, eine Wasch-, Trocknungs- oder Polierwalze für Fahrzeugwasch- und/oder -polieranlagen der eingangs erwähnten Art zu schaffen, bei der die Arbeitselemente ohne Demontage der Tragscheibe von dem Walzenkern einzeln leicht austauschbar sind.The invention is therefore based on the object Washing, drying or polishing roller for vehicle washing and / or -polishing systems of the type mentioned at the beginning create the work elements without disassembly the supporting disc can easily be replaced individually by the roller core are.

Dies wird nach der Erfindung dadurch erreicht, daß zur lösbaren Verbindung jedes Arbeitselementes mit der Tragscheibe ein Verbindungsteil aus steifem Material vorgesehen ist, welches durch eine in der Tragscheibe vorgesehene Öffnung gesteckt ist und mit jedem seiner beiden Enden in jeweils eine am Befestigungsende ausgebildete Tasche oder Ausnehmung eingreift, wobei die beiden Taschen oder Ausnehmungen jedes Arbeitselementes an entgegengesetzten Seiten einer durch die zugehörige Tragscheibe verlaufenden Ebene vorgesehen sind. This is achieved according to the invention in that releasable connection of each work element with the Carrying disc is a connecting part made of rigid material is provided, which by a in the support plate provided opening is inserted and with each of its both ends in one each formed at the fastening end Pocket or recess engages, the two Pockets or recesses of each work element on opposite Sides of a through the associated support disc trending level are provided.

Dank dieser Ausgestaltung können die Arbeitselemente bei Beschädigung oder Verschleiß sehr leicht von der Tragscheibe demontiert bzw. wieder an dieser montiert werden, ohne daß hierfür die Walze aus der Fahrzeugwasch- oder -polieranlage ausgebaut werden müßte. Auch eine Zerlegung der Walze selbst ist nicht erforderlich. Da außerdem die Arbeitselemente im Bereich ihres Befestigungsendes nicht mehr gefaltet werden müssen, ergeben sich keine unterschiedlichen Drehmomente beim Wechsel der Drehrichtung der Walze. Bei der neuen Befestigungsart der Arbeitselemente kann das Verbindungsteil mit seinen Enden so in die Taschen oder Ausnehmungen des Arbeitselementes eingreifen, daß auch das Befestigungsende des Arbeitselementes im wesentlichen parallel zur Walzenachse verläuft. Dies wiederum hat den Vorteil, daß eine bessere Drehmitnahme der Arbeitselemente durch die Borsten gewährleistet ist. Da die Borsten jeweils auf eine sich parallel zur Walzenachse erstreckende Fläche des Befestigungsendes auftreffen, kann die Drehmitnahme der Arbeitselemente sehr genau vorausbestimmt werden. Diese Drehmitnahme kann dadurch variiert werden, daß die "Eintauchtiefe" der Befestigungsenden der Arbeitselemente in die Borsten verändert wird. Da die Arbeitselemente an ihren Befestigungsenden nicht gefaltet zu sein brauchen, decken sie die Sicht auf die Borsten weitgehend ab, so daß die Borsten für den Benutzer der Fahrzeugwasch- und/oder -polieranlage unsichtbar bleiben und ihm auch optisch der Eindruck vermittelt wird, daß sein Fahrzeug nur durch die textilartigen Arbeitselemente und nicht durch Borsten gewaschen wird. Thanks to this configuration, the working elements in the event of damage or wear very easily from the Disassembled or reassembled the support disk be, without this the roller would have to be removed from the vehicle washing or polishing system. It is also not necessary to disassemble the roller itself. Since also the work elements in the area of their fastening end can no longer be folded there are no different torques when changing the direction of rotation of the roller. With the new one The connecting element can be used to fasten the working elements with its ends in the pockets or recesses of the working element that also engage the fastening end of the working element essentially parallel runs to the roller axis. This in turn has the advantage that a better rotation of the work elements the bristles is guaranteed. Because the bristles each on a parallel to the roll axis Impact the surface of the fastening end, the rotary drive of the working elements is determined very precisely become. This turning entrainment can be varied by that the "immersion depth" of the fastening ends of the Working elements in the bristles is changed. Since the Working elements are not folded at their fastening ends need to be, they cover the view of the Bristles largely off, so that the bristles for Vehicle washing and / or polishing system users stay invisible and give it the visual impression is conveyed that his vehicle only through the textile-like working elements and not through bristles is washed.

In Figur 1 und 2 ist mit A die Walzenachse (Drehachse) einer Wach-, Trocknungs- oder Polierwalze - in Folgendem nur noch Walze genannt - bezeichnet. Auf einem nicht dargestellten Walzenkern sind in axialen Abständen voneinander mehrere in Radialebenen zur Walzenachse A angeordnete Tragscheiben 1 vorgesehen. Die Tragscheiben 1 bestehen vorzugsweise aus Kunststoff, sie können jedoch auch gegebenenfalls aus Filz oder einem ähnlichen Material bestehen. Zwischen den Scheiben 1 sind entweder, wie es in Figur 1, links oben, dargestellt ist, von einem Borstenträger getragene Borsten 2 oder, wie es in Figur 1, links unten, dargestellt ist, Distanzscheiben 3 aus Schaumstoff angeordnet. In letzterem Fall erfolgt die Drehmitnahme der Tragscheiben 1 dadurch, daß die Distanzscheiben reibschlüssig auf dem nicht dargestellten Walzenkern angeordnet sind und axial an die Tragscheibe 1 angedrückt werden. Bei Verwendung von Borsten 2 sind die nicht dargestellten Borstenträger mit dem Walzenkern verbunden und die Übertragung des Drehmoments erfolgt hauptsächlich dadurch, daß die äußeren Enden der Borsten 2 am Befestigungsende 4 der Arbeitselemente 5 zur Anlage kommen, wie es beispielsweise in dem DE 295 18 089 U1 beschrieben ist. Je weiter die Befestigungsenden 4 in radialer Richtung in die Borsten 2 eintauchen und je breiter die Befestigungsenden 4 in Richtung der Walzenachse sind, desto größer ist das von den Borsten 2 auf die Arbeitselemente 5 übertragbare Drehmoment.In Figures 1 and 2, A is the roller axis (axis of rotation) a waxing, drying or polishing roller - in the following just called roller - called. On a not shown Roll core are at axial distances from each other several arranged in radial planes to the roller axis A. Support discs 1 provided. The support disks 1 exist preferably plastic, but they can also made of felt or the like, if necessary Material. Between the disks 1 are either as shown in Figure 1, top left, by one Bristle holder worn bristles 2 or as in Figure 1, shown bottom left, spacers 3 arranged from foam. In the latter case the rotational driving of the support disks 1 in that the Spacers frictionally on the not shown Roll core are arranged and axially to the support disc 1 can be pressed. When using bristles 2 are the bristle carriers, not shown, with the Roll core connected and the transmission of the torque is done mainly by the fact that the outer ends of the Bristles 2 at the fastening end 4 of the working elements 5 come to the system, such as in the DE 295 18 089 U1 is described. The farther the attachment ends 4 Dip into the bristles 2 in the radial direction and the wider the fastening ends 4 in the direction the roller axis, the larger that of the bristles 2 transferable to the working elements 5 Torque.

Die Arbeitselemente 5 sind streifenförmig ausgebildet und sie bestehen vorzugsweise aus Filz oder Vlies. Als Material für die Arbeitselemente 5 kommt aber auch Kunstleder, Leder oder fellartiges Material sowie sonstiges Textilmaterial in Frage. Jedes Arbeitselement 5 ist an seinem Arbeitsende 6 vorzugsweise durch mehrere Einschnitte 7 in einzelne Streifen oder Finger unterteilt. Bei frei rotierender Walze sind die Arbeitselemente 5 im wesentlichen radial zur Walzenachse A angeordnet und ihre Arbeitsflächen 6a verlaufen im wesentlichen parallel zur Walzenachse. Wenn die Arbeitsflächen 6a auf die Oberfläche des zu waschenden, zu trocknenden oder zu polierenden Fahrzeugs auftreffen, dann schmiegen sie sich der Kontur dieser Oberfläche an. Auch die Befestigungsenden 4 der Arbeitselemente 5 verlaufen vorzugsweise im wesentlichen parallel zur Walzenachse A, damit die gewünschte Drehmomentsübertragung zwischen den Borsten 2 und den Befestigungsenden 4 der Arbeitselemente 5 stattfinden kann. The working elements 5 are strip-shaped and they are preferably made of felt or fleece. As Material for the working elements 5 also comes Synthetic leather, leather or fur-like material as well other textile material in question. Every work item 5 is preferably 6 at its working end through several cuts 7 in individual strips or Fingers divided. With the roller rotating freely the working elements 5 substantially radially Roller axis A arranged and their work surfaces 6a run essentially parallel to the roller axis. If the work surfaces 6a to the surface of the washing, drying or polishing vehicle hit, then they nestle the contour this surface. The fastening ends 4 of the working elements 5 preferably run essentially parallel to the roller axis A, so that the desired Torque transmission between the bristles 2 and Fastening ends 4 of the working elements 5 take place can.

Wie weiterhin insbesondere aus den Figuren 3, 4, 5 und 7 hervorgeht, ist das Befestigungsende 4 jedes Arbeitselementes 5 durch einen radialen Einschnitt 8 in zwei getrennte Endabschnitte 4a, 4b geteilt. Die Endabschnitte 4a, 4b sind beiderseits der Tragscheibe 1 angeordnet, die sich mehr oder weniger tief in den Einschnitt 8 hineinerstreckt. Zur lösbaren Verbindung jedes Arbeitselementes 5 mit der Tragscheibe 1 ist ein Verbindungsteil 9, 10 oder 11 vorgesehen, welches sich jeweils durch eine in der Tragscheibe 1 vorgesehene Öffnung 12 bzw. 12a, 12b (siehe Figur 2) erstreckt. Die Verbindungsteile 9, 10, 11 können aus Metall, wie z.B. rostfreiem Stahl, oder auch aus Kunststoff, oder auch aus beiden, nämlich Metall, welches von Kunststoff ummantelt ist, bestehen. Jedes dieser Verbindungsteile 9, 10, 11 greift mit jeweils einem Ende 9a, 9b bzw. 10a, 10b bzw. 11a, 11b jeweils in eine am Endabschnitt 4a, 4b ausgebildete Tasche 13a, 13b bzw. 14a, 14b bzw. 15a, 15b oder in eine Ausnehmung 16a, 16b ein, wie es nachstehend noch näher beschrieben wird.As furthermore in particular from FIGS. 3, 4, 5 and 7 emerges, the fastening end 4 of each working element 5 through a radial incision 8 in two divided separate end portions 4a, 4b. The end sections 4a, 4b are arranged on both sides of the support disk 1, which are more or less deep in the incision 8 stretched in. For detachable connection of each work element 5 with the support plate 1 is a connecting part 9, 10 or 11 is provided, which is characterized by an opening 12 provided in the support disk 1 or 12a, 12b (see Figure 2) extends. The connecting parts 9, 10, 11 can be made of metal, e.g. stainless steel, or also from plastic, or also from both, namely Metal, which is encased by plastic, exist. Each of these connecting parts 9, 10, 11 engages with each one end 9a, 9b or 10a, 10b or 11a, 11b each in one formed at the end section 4a, 4b Pocket 13a, 13b or 14a, 14b or 15a, 15b or in a recess 16a, 16b, as follows is described in more detail.

Bei den in Figur 1 - 3 und 4 dargestellten Ausführungsbeispielen ist das Verbindungsteil ein sich senkrecht zur Tragscheibe 1 erstreckender Stift 9. Die Taschen 13a, 13b bzw. 14a, 14b sind jeweils durch einen Umschlag eines Teiles des jeweiligen Endabschnittes 4a bzw. 4b gebildet. Nach dem Umschlagen des Endabschnittes ist der umgeschlagene Teil zweckmäßig durch Nähen mit dem übrigen Endabschnitt 4a bzw. 4b verbunden, um somit die Tasche abzugrenzen und auszuformen. Anstelle von Nähen kommen jedoch auch Kleben, Schweißen (bei Kunststoff), Nieten, Klettverschlüsse, Druckknöpfe oder dgl. in Frage, wobei jedoch das Nähen die einfachste und haltbarste Verbindung sein dürfte. Das Nähen zur Ausgestaltung der Taschen erfolgt, bevor die einzelnen Arbeitselemente 5 mit der Tragscheibe 1 verbunden werden.In the embodiments shown in Figures 1-3 and 4 the connecting part is a vertical pin 9 extending to the supporting disk 1. The pockets 13a, 13b and 14a, 14b are each through an envelope a part of the respective end section 4a or 4b educated. After turning the end section is the folded part is expediently sewn with the remaining end section 4a and 4b connected to the Define and shape the bag. Instead of sewing but also come gluing, welding (with plastic), Rivets, Velcro fasteners, snap fasteners or the like in question, however, sewing is the easiest and most durable Connection should be. Sewing to design the pockets take place before the individual work items 5 are connected to the support plate 1.

Bei dem in Figur 1 - 3 dargestellten Ausführungsbeispiel sind die beiden Taschen 13a, 13b an ihren der Tragscheibe 1 abgewandten Enden jeweils durch eine Naht 16 geschlossen. Die Nähte 17 sind zweckmäßig so genäht, daß sie jede Tasche 13a, 13b zu ihrem inneren Ende hin, d.h. zur Tragscheibe 1 hin, eine Erweiterung 18 aufweist. Die Verbindung des Arbeitselementes 5 mit der Tragscheibe 1 erfolgt bei diesem Ausführungsbeispiel dadurch, daß man zunächst den Stift 9 mit seinem Ende 9b beispielsweise in die Tasche 13b einsteckt und dann das andere Ende 9a durch die Öffnung 12 in der Tragscheibe 1 steckt. Der Endabschnitt 4a wird dann von der Tragscheibe 1 weg gezogen und das andere Ende 9a des Stiftes in die Tasche 13a eingeführt, wobei die Erweiterung 18 das Einführen erleichtert. Der Endabschnitt 4a wird dann bis zur Tragscheibe 1 geschoben, womit die Befestigung des Arbeitselementes 5 an der Tragscheibe 1 abgeschlossen ist. In umgekehrter Weise kann das Arbeitselement wieder von der Tragscheibe 1 gelöst werden, wenn es verschlissen oder beschädigt ist. Wenn man die Drehmitnahme des Arbeitselementes 5 erhöhen will, dann kann man den Stift gemäß Figur 2 in eine radial weiter innen liegende Öffnung 12a oder 12b stecken. Dies kann bei einigen Arbeitselementen oder auch bei allen erfolgen. Auf diese Weise kann man durch Veränderung der "Eintauchtiefe" der Arbeitselemente 5 zwischen die Borsten 2 das vom Walzenkern über die Borsten 2 auf die Arbeitselemente 5 übertragbare Drehmoment leicht verändern und auf diese Weise die Arbeitsleistung der jeweiligen Walze optimieren. In the embodiment shown in Figures 1-3 are the two pockets 13a, 13b on their support disk 1 opposite ends each closed by a seam 16. The seams 17 are appropriately sewn so that they each Pocket 13a, 13b towards its inner end, i.e. to the support disk 1 out, has an extension 18. The connection of the working element 5 with the support plate 1 in this embodiment in that first the pin 9 with its end 9b for example in the Pocket 13b and then through the other end 9a the opening 12 is in the support plate 1. The end section 4a is then pulled away from the supporting disk 1 and the other end 9a of the pin into the pocket 13a introduced, the extension 18 facilitates insertion. The end section 4a is then up to the support disk 1 pushed, with which the attachment of the working element 5 is completed on the support plate 1. Conversely, the working element can be used again can be released from the support plate 1 when it is worn out or is damaged. If you take the turning element of the work element 5 wants to increase, then you can according to the pen Figure 2 in a radially inner opening Insert 12a or 12b. This can be the case with some work items or done with all. In this way can be changed by changing the "immersion depth" of the Working elements 5 between the bristles 2 that of the roll core transferable to the working elements 5 via the bristles 2 Change torque slightly and on this How to optimize the work performance of the respective roller.
