Description

Die Erfindung betrifft eine Vorrichtung gemäss dem Oberbegriff des Anspruchs 1 zum Entfernen von Markierungen auf Strassendecken od. dgl. Markierungen auf Strassendecken od. dgl. müssen häufig entfernt werden. Es ist bekannt, zum Entfernen dieser durch Farbauftrag oder Beschichtung hergestellten Markierungen Walzen zu verwenden, die ähnlich wie Abrichtwalzen für Schleifscheiben eine Anzahl von hartmetallbestücken, über den Umfang verteilten Zähnen aufweisen und unter entsprechender Anpressung gegen die Strassenoberfläche bzw. den Farbbelag abgerollt werden. Dabei ist es - wie bei Abrichtwalzen - bekannt, diese Walzen aus einer Anzahl aneinanderliegender Sternscheiben zusammenzusetzen.The invention relates to a device according to the preamble of claim 1 for removing markings on road surfaces or the like. Markings on road surfaces or the like must frequently be removed. It is known to use rollers to remove these markings produced by paint application or coating, which, like dressing rollers for grinding wheels, have a number of carbide tipped teeth, teeth distributed over the circumference, and are rolled off with appropriate pressure against the road surface or the ink coating. It is known - as with dressing rolls - to assemble these rolls from a number of star disks placed one against the other.

Um eine ausreichende Abrollgeschwindigkeit zu erreichen, ist es dazu bekannt, diese Schrämwalzen an den Achsen eines Achsenkreuzes anzubringen, das an einer vertikal zur Strassendecke angeordneten motorangetriebenen Spindel angebracht ist. Ein wesentliches Problem bei dieser Art von « Demarkierungsvorrichtungen ergibt sich daraus, dass der Strassenbelag, insbesondere im Bereich von Randmarkierungen sehr uneben sein kann, und daher der bis zu 2 mm oder darüber dicke Farbbelag in Vertiefungen durch die in einer Ebene drehenden Walzen nur unvollständig abgearbeitet werden kann, ohne dass die Erhebungen der Strassendecke ebenfalls abgearbeitet werden. Dies führt jedoch zu einer unnötigen Abarbeitung von Fahrbelag mit einem erheblichen Zeit- und Werkzeugaufwand.In order to achieve a sufficient rolling speed, it is known to attach these scraper rollers to the axes of an ax interlock, which is attached to a motor-driven spindle arranged vertically to the road surface. A major problem with this type of "demarcation device arises from the fact that the road surface, particularly in the area of edge markings, can be very uneven, and therefore the up to 2 mm or more thick colored surface in recesses is only incompletely processed by the rollers rotating in one plane can be processed without the elevations of the road surface also being processed. However, this leads to an unnecessary processing of the driving surface with a considerable expenditure of time and tools.

Um eine bessere Anpassung der an den Achsen des Achsenkreuzes gelagerten Schrämwalzen an Bodenunebenheiten zu erreichen, ist es bekannt, das starre Achsenkreuz über ein Gummifedereiement od. dgl. in Richtung auf die Strassendecke zu vorgespannt an der Spindel zu lagern. Dies führt jedoch bei Bodenunebenheiten zu einer ungleichförmigen Verteilung des auf die einzelnen Achsen des Achsenkreuzes ausgeübten vertikalen Anstelldruckes. Dadurch wird eine Verminderung der Arbeitsleistung, d. h. eine Erhöhung des Zeitaufwandes bewirkt. Ausserdem arbeiten auch bei dieser bekannten Vorrichtung die Schrämwalzen, die auf den Achsen des starren Achsenkreuzes gelagert sind, in einer, wenn auch gegen die Achse der Spindel und damit gegen die Strassenoberfläche schrägstellbaren Ebene. Dadurch ist nur eine beschränkte Anpassung an Bodenunebenheiten möglich.In order to achieve a better adaptation of the cutting rollers mounted on the axes of the axis cross to uneven ground, it is known to mount the rigid axis cross over a rubber spring element or the like in the direction of the road surface too prestressed on the spindle. However, this leads to an uneven distribution of the vertical contact pressure exerted on the individual axes of the ax cross in the event of uneven ground. This will reduce labor performance, i.e. H. causes an increase in time expenditure. In addition, in this known device, the cutting rollers, which are mounted on the axes of the rigid axis cross, work in a plane that can be tilted against the axis of the spindle and thus against the road surface. This means that only a limited adaptation to uneven floors is possible.

Es ist die der Erfindung zugrunde liegende Aufgabe, eine derartige bekannte Vorrichtung zum Entfernen von Markierungen auf Strassendecken od. dgl. so weiterzubilden, dass eine wesentlich bessere Anpassung an Unebenheiten der Strassendecke mit gleichförmigem Arbeitsdruck für jede der an je einer Achse des Achsenkreuzes gelagerten Schrämwalzen erreicht wird, und damit die Wirkung und die Arbeitsleistung bei grösstmöglicher Schonung der Strassendecke wesentlich verbessert wird.It is the object of the invention to develop such a known device for removing markings on road surfaces or the like in such a way that a substantially better adaptation to unevenness of the road surface is achieved with a uniform working pressure for each of the scraper rollers mounted on one axis of the axis cross is, and thus the effect and work performance with the greatest possible protection of the road surface is significantly improved.

Diese Aufgabe wird gemäss des Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 enthaltenen Massnahmen gelöst.This object is achieved according to the invention by the measures contained in the characterizing part of claim 1.

Gemäss der Erfindung wird also jede der Schrämwalzen, unabhängig von der Lage der anderen Schrämwalzen des Achsenkreuzes mit einem von ihrer Höhenlage im wesentlichen unabhängigen Arbeitsdruck gegen die Strassendecke angepresst, wobei der Arbeitsdruck im wesentlichen von dem jeder Schrämwalze zugeordneten Federelement abhängt. Dadurch ist die Arbeitswirkung jeder der Schrämwalzen unabhängig von ihrer Höhenlage und damit wie die Arbeitswirkung aller Schrämwalzen gemeinsam gleich. Dadurch wird eine wesentliche Erhöhung der Arbeitsleistung erreicht. Dies ist, abgesehen von der Kostenfrage, insbesondere für die Verkürzung von Zeiten der Verkehrsbehinderung durch Baustellen auf Autobahnen oder Bundesstrassen von ganz wesentlicher Bedeutung.According to the invention, therefore, each of the cutting rollers, regardless of the position of the other cutting rollers of the axis cross, is pressed against the road surface with a working pressure that is essentially independent of its height, the working pressure essentially depending on the spring element assigned to each cutting roller. As a result, the working effect of each of the cutting rollers is independent of their altitude and thus, like the working effect of all cutting rollers, is the same. This leads to a significant increase in work performance. Apart from the question of costs, this is very important, in particular for the reduction of times of traffic obstruction caused by construction sites on motorways or federal roads.

Durch die in den Ansprüchen 5-6 gekennzeichnet Aufhängung der Spindel mit Achsenkreuz, zusammen mit der Spindellagerung und den übrigen mit der Spindellagerung verbundenen Bauelementen, z. B. der Schutzabdeckung des Achsenkreuzes mit den Schrämwalzen wird der Abstand der Spindel und damit der Anpressdruck der Schrämwalzen gegen den Fahrbelag genau einstellbar, ohne dass die freie Beweglichkeit der Vorrichtung behindert wird.Characterized in the claims 5-6 suspension of the spindle with axis cross, together with the spindle bearing and the other components connected to the spindle bearing, z. B. the protective cover of the axis cross with the scraper rollers, the distance of the spindle and thus the contact pressure of the scraper rollers against the driving surface is precisely adjustable without the free mobility of the device being impeded.

Dabei können bei der Ausführungsform nach Anspruch 6 die Winkelhebel auch dadurch gebildet werden, dass entsprechende Einzelarme fest in der für die Verbindung mit anderen Bauteilen günstigsten Lage an den Achsen angebracht sind. Durch diese Anordnung wird es möglich, nur ein aus je einem langen Arm der beiden Winkelhebel und einer Schubstange bestehendes Lenkerwerk zu verwenden, während die Achsen an zwei in Abstand liegenden Punkten aufgehängt sind. Es werden dann auch zwei Zwischenstücke verwendet, die über einen gemeinsamen Querzapfen am Gerätewagen angehängt sind.In the embodiment according to claim 6, the angle levers can also be formed in that corresponding individual arms are firmly attached to the axles in the most favorable position for connection to other components. This arrangement makes it possible to use only one linkage consisting of one long arm each of the two angle levers and one push rod, while the axles are suspended at two spaced apart points. Then two intermediate pieces are used, which are attached to the equipment trolley via a common cross pin.

Die Erfindung wird im folgenden anhand der Zeichnungen an Ausführungsbeispielen näher erläutert.The invention is explained below with reference to the drawings of exemplary embodiments.

In den Zeichnungen zeigen :

  • Fig. 1 einen Axialschnitt durch eine Spindel mit Achsenkreuz und Schrämwalzen,
  • Fig. 2 ein kinematisches Schema des Parallelenkerwerks zur höhenverstellbaren Aufhängung der Spindel mit der Lagerung an einem Fahrwerk. und
  • Fig. 3 eine Draufsicht auf einen Gerätewagen, an dem mehrere Demarkierungsvorrichtungen hintereinander anhängbar sind.
The drawings show:
  • 1 shows an axial section through a spindle with a cross-piece and cutting rollers,
  • Fig. 2 is a kinematic diagram of the parallel link mechanism for the height-adjustable suspension of the spindle with the bearing on a chassis. and
  • Fig. 3 is a plan view of an equipment cart on which several demarcation devices can be attached one behind the other.

Bei der in Fig. 1 dargestellten Ausführungsform ist die Spindel 1 mit dem Kopf 2 des Achsenkreuzes in einem Stück ausgebildet. Aus fertigungstechnischen Gründen kann selbstverständlich auch der Kopf 2 gesondert hergestellt und mit der Spindel 1 in bekannter Weise verbunden werden. Die Spindel 1 ist mittels Wälzlagern 3 in einem Spindelgehäuse 4 gelagert. Die axiale Lage der Spindel 1 im Gehäuse 4 ist über die Lager 3 durch einen auf einem Gewindeabschnitt 5 der Spindel aufgeschraubten Gewindering 6 und eine Dichtung 7 sichergestellt. Das Lagergehäuse 4 ist mit einem unteren Flansch 8 an einem Schutzgehäuse 9 verschraubt, welches den Kopf 2 mit den daran angebrachten Achsenkreuz und den Schrämwalzen 10 abdeckt.In the embodiment shown in Fig. 1, the spindle 1 is formed in one piece with the head 2 of the axis cross. From manufacturing For technical reasons, the head 2 can of course also be manufactured separately and connected to the spindle 1 in a known manner. The spindle 1 is mounted in a spindle housing 4 by means of roller bearings 3. The axial position of the spindle 1 in the housing 4 is ensured via the bearings 3 by a threaded ring 6 screwed onto a threaded section 5 of the spindle and a seal 7. The bearing housing 4 is screwed to a protective housing 9 with a lower flange 8, which covers the head 2 with the axis cross attached to it and the cutting rollers 10.

Am unteren Ende des Kopfes 2 sind in gleichmässiger Umfangsteilung (beim Ausführungsbeispiel vier) Paare von Laschen 11 ausgebildet, die Querbohrungen 12 aufweisen. Zwischen jedem Paar von Laschen 11 ist durch die Bohrungen ein Achshebel 14 um einem durch die Bohrungen 12 gesteckten Bolzen 13 schwenkbar angeordnet. Der Achshebel 14 weist eine etwa rechtwinklig zur Spindelachse wegragende Achse 15, sowie einen in Fig.1 nach oben wegragenden Arm 16 auf. Im Arm 16-ist eine Blindbohrung 17 und gegenüberliegend im Kopf 2 der Spindel 1 eine Blindbohrung 18 vorgesehen. In diese Bohrungen ist eine Schraubenfeder 19 eingelegt, die den Hebelarm 16 nach aussen, und damit die rechtwinklig von diesem Hebelarm wegragende Achse 15 nach unten vorspannt.At the lower end of the head 2, pairs of tabs 11 are formed in a uniform circumferential division (four in the exemplary embodiment), which have transverse bores 12. Between each pair of tabs 11, an axle lever 14 is pivotally arranged through the bores around a bolt 13 inserted through the bores 12. The axis lever 14 has an axis 15 projecting approximately at right angles to the spindle axis, and an arm 16 projecting upwards in FIG. A blind bore 17 is provided in the arm 16 and a blind bore 18 is provided opposite in the head 2 of the spindle 1. In these holes, a coil spring 19 is inserted, which biases the lever arm 16 outwards, and thus the axis 15 projecting at right angles from this lever arm downwards.

Auf der Achse 15 ist eine Büchse 20 aus verschleissfestem Material aufgesetzt und mittels einer Scheibe und Mutter 22 oder auf andere bekannte Weise axial und in Umfangsrichtung festgelegt. Auf der Büchse 20 sitzt eine Anzaht von Sternscheiben 21, die zusammen die Schrämwalze 10 bilden. Die Sternscheiben 21 haben ein geringes Spiel gegen die Büchse 20, so dass sie auf dieser drehen können.A bushing 20 made of wear-resistant material is placed on the axis 15 and fixed axially and in the circumferential direction by means of a washer and nut 22 or in another known manner. On the sleeve 20 there is a number of star disks 21 which together form the cutting roller 10. The star disks 21 have a slight play against the sleeve 20 so that they can rotate on it.

Zum Betrieb wird die Spindel 1 in Drehung gesetzt und gegen die Arbeitsfläche abgesenkt. Wenn die aus den Sternscheiben 21 gebildeten Schrämwalzen 10 in Berührung mit der Arbeitsfläche gelangen, wird die Achse 15 nach oben, und damit der Hebelarm 16 unter gleichzeitiger Zusammendrückung der Feder 19 nach innen um den Zapfen 13 verschwenkt. Dabei übt die Feder 19 eine zunehmende Reaktionskraft gegen diese Schwenkbewegung aus, so dass die Schrämwalze 10 mit einer von der Absenkung abhängenden, zunehmenden Kraft gegen die Arbeitsfläche angepresst wird. Wenn die Schrämwalze 10 eine Bodenunebenheit durchläuft, wird diese Bodenunebenheit durch eine geringfügige Zusammenpressung oder Ausdehnung der Feder 19 ausgeglichen. Bei diesen im Verhältnis zum Gesamtfederweg geringfügigen Längenänderungen der Feder 19 ändert sich der Anstelldruck der Schrämwalzen 10 gegen den Boden nur geringfügig. Dadurch wird ein praktisch gleichförmiger Arbeitsdruck, unabhängig von den üblicherweise auftretenden Bodenunebenheiten ausgeübt.For operation, the spindle 1 is set in rotation and lowered against the work surface. When the cutting rollers 10 formed from the star disks 21 come into contact with the working surface, the axis 15 is pivoted upward, and thus the lever arm 16 is pivoted inward about the pin 13 while the spring 19 is compressed. The spring 19 exerts an increasing reaction force against this pivoting movement, so that the cutting roller 10 is pressed against the work surface with an increasing force that depends on the lowering. If the cutting roller 10 passes through an uneven ground, this uneven ground is compensated for by a slight compression or expansion of the spring 19. With these changes in length of the spring 19, which are minor in relation to the total spring travel, the setting pressure of the cutting rollers 10 against the ground changes only slightly. As a result, a practically uniform working pressure is exerted, regardless of the unevenness in the floor that usually occurs.

Die in Fig. 1 dargestellte Vorrichtung kann im Ganzen an einem Gerätewagen angebracht und durch bekannte Anordnungen gegen den Boden angestellt werden. Da jedoch der Gerätewagen einen relativ grossen Achs- und Radabstand hat, und die Räder gefedert sind, und damit Krümmungen auf der Fahrbahn sich in einer grossen Änderung des Abstandes der Spindel gegen den Boden auswirken können, wird vorzugsweise jede Vorrichtung gemäss Fig. 1, wie in Fig. 2 schematisch dargestellt, direkt auf gegen den Boden ablaufenden Rollen gelagert. Um eine gleichförmige Höhen-verstellung, ohne Winkelverlagerung der Spindelachse gegen den Boden zu erreichen, sind die Räder mit der Spindellagerung vorzugsweise höhenverstellbar über ein Parallellenkerwerk verbunden, das eine gleichmässige Höhen-verstellung aller Räder sicherstellt.The device shown in Fig. 1 can be attached as a whole to an equipment cart and can be set against the ground by known arrangements. However, since the equipment trolley has a relatively large center-to-center distance and wheel spacing, and the wheels are sprung, and therefore curvatures on the roadway can result in a large change in the spacing of the spindle from the ground, each device according to FIG shown schematically in Fig. 2, mounted directly on rollers running against the floor. In order to achieve a uniform height adjustment without angular displacement of the spindle axis against the ground, the wheels are preferably connected to the spindle bearing in a height-adjustable manner via a parallel link mechanism, which ensures a uniform height adjustment of all wheels.

In Fig. 2 ist ein Ausführungsbeispiel eines derartigen Parallellenkerwerkes anhand eines kinematischen Schemas dargestellt. Dabei sind auf der Oberseite des Gehäuses 9 vorzugsweise zwei parallel in Abstand voneinander liegende Arme 30 angeschweisst. Jeder der Arme 30 ist mit einem Zwischenstück 31 verschweisst. Die Zwischenstücke weisen vertikale Langlöcher 32 auf. Durch die Langlöcher 32 aller Zwischenstücke verläuft ein Querzapfen 33, der mit dem Gerätewagen verbunden ist. Ferner ist mit dem Gehäuse 9 ein Stützrohr 34 verschweisst.An exemplary embodiment of such a parallel link mechanism is shown in FIG. 2 on the basis of a kinematic scheme. Two arms 30, which are spaced apart and parallel to one another, are preferably welded onto the top of the housing 9. Each of the arms 30 is welded to an intermediate piece 31. The intermediate pieces have vertical elongated holes 32. A transverse pin 33, which is connected to the equipment trolley, runs through the elongated holes 32 of all intermediate pieces. Furthermore, a support tube 34 is welded to the housing 9.

Diese, in sich starre Anordnung ist mit den Rädern durch ein Lenkerwerk verbunden. Dieses Lenkerwerk besteht aus einem ersten Winkelhebei 35 und einem zweiten Winkelhebel 36. Die freien Enden der langen Arme der Winkelhebel 35 und 36 sind an den Enden einer Schubstange 37 angelenkt. Am Winkelpunkt der Winkelhebel 35 und 36 liegen Radachsen 38, die an ihren Enden strichpunktiert dargestellte Räder 39 tragen. Das freie Ende des kurzen Armes des ersten Winkelhebels 35 ist bei 40 am Gehäuse 9 angelenkt, während das freie Ende des kurzen Armes des zweiten Winkelhebels 36 bei 41 an dem Zwischenstück 31 angelenkt ist.This rigid arrangement is connected to the wheels by a link mechanism. This linkage consists of a first angle lever 35 and a second angle lever 36. The free ends of the long arms of the angle levers 35 and 36 are articulated on the ends of a push rod 37. At the angular point of the angle levers 35 and 36 there are wheel axles 38 which carry wheels 39 shown in broken lines at their ends. The free end of the short arm of the first angle lever 35 is articulated at 40 on the housing 9, while the free end of the short arm of the second angle lever 36 is articulated at 41 on the intermediate piece 31.

Mindern ersten Winkelhebel 35 starr verbunden, ist ein Stellhebel 42, der eine Spindelmutter 43 trägt, in der eine Spindel 44 eingeschraubt ist. Das eine Ende 45 der Spindel ragt durch einen nicht dargestellten Vertikalschlitz an der in Fig. 2 linken Seite des Rohres 43 und ist an einer in diesem Rohr 43 verschiebbaren Kugel bzw. bei Verwendung eines Vierkantrohres an einer Rolle axial festgelegt, aber drehbar. Am anderen Ende ist an der Spindel 44 ein Handrad 46 angebracht. Wenn die Spindel 44 mittels des Handrades 46 so gedreht wird, dass der Hebel 42 sich im Pfeilrichtung A vom Rohr 34 wegbewegt, bewegt sich entsprechend auch die Anlenkstelle 40 des kurzen Armes des Winkelhebels 35 in Richtung des Pfeiles A nach oben, und gleichzeitig der lange Arm des Winkelhebels 35 in Pfeilrichtung A nach aussen. Durch die Schubstange 37 wird entsprechend auch der lange Arm des zweiten Winkelhebels 36 in Richtung des Pfeiles A nach innen bewegt. Dadurch wird der kurze Arm des Winkelhebels 36 in Pfeilrichtung A nach oben verschwenkt und bewegt über den Anlenkpunkt 41 das Zwischenstück 31 und damit auch über die Arme 30 das Gehäuse 9 nach oben. Da der erste Winkelhebel 35 und der zweite Winkelhebel 36 identisch sind, bewegt sich das Gehäuse 9 gegen die Räder 39 in einer Parallelbewegung nach oben. Bei umgekehrter Verstellung der Spinder 44 erfolgt die gleiche Parallelbewegung entgegengesetzt, d. h. das Gehäuse 9 bewegt sich gegen die Räder nach unten, und die Schrämwalzen 10 werden gegen den Boden angestellt.The first angle lever 35 is rigidly connected to an adjusting lever 42, which carries a spindle nut 43, in which a spindle 44 is screwed. One end 45 of the spindle protrudes through a vertical slot (not shown) on the left-hand side of the tube 43 in FIG. 2 and is axially fixed but rotatable on a ball that can be displaced in this tube 43 or, when using a square tube, on a roller. At the other end, a handwheel 46 is attached to the spindle 44. If the spindle 44 is rotated by means of the handwheel 46 so that the lever 42 moves away from the tube 34 in the direction of arrow A, the articulation point 40 of the short arm of the angle lever 35 also moves upward in the direction of arrow A, and at the same time the long one Arm of the angle lever 35 in the direction of arrow A outwards. The long arm of the second angle lever 36 is accordingly moved inwards in the direction of arrow A by the push rod 37. As a result, the short arm of the angle lever 36 is pivoted upward in the direction of arrow A and moves the intermediate piece 31 via the articulation point 41 and thus also via the Arms 30 up the housing 9. Since the first angle lever 35 and the second angle lever 36 are identical, the housing 9 moves upwards in a parallel movement against the wheels 39. With the reverse adjustment of the spindle 44, the same parallel movement takes place in the opposite direction, ie the housing 9 moves downwards against the wheels, and the cutting rollers 10 are set against the ground.

In Fig. 3 ist in Draufsicht ein Gerätewagen zum Anhängen von mehreren Vorrichtungen gemäss Fig. 1 und 2 dargestellt. Der Wagen hat eine Plattform 50, die sich auf vier Räder 51 in bekannter Weise abstützt. Auf der Plattform sind Führungen für Querschienen 52 angebracht, in denen diese nach beiden Seiten des Wagens verschiebbar sind. An den Querschienen 52 sind Laschenpaaare 54 anbringbar, in denen der Querbolzen 33 (Fig. 2) gelagert werden kann. Auf dem Querbolzen 33 sitzen die Zwischenstücke 31 mit ihren Langlöchern.3 shows a top view of an equipment trolley for attaching several devices according to FIGS. 1 and 2. The carriage has a platform 50 which is supported on four wheels 51 in a known manner. On the platform guides for cross rails 52 are attached, in which they can be moved to both sides of the car. Pairs of tabs 54 can be attached to the transverse rails 52, in which the transverse bolt 33 (FIG. 2) can be mounted. On the cross bolt 33, the intermediate pieces 31 sit with their elongated holes.

Auf der Plattform 50 sind nicht dargestellte Aggregate, z. B. ein mittels Brennkraftmaschine betriebenes Stromaggregat, das oberhalb der Lagergehäuse 4 (Fig. 1) über Zwischenstücke mit diesen verflanschte Elektromotore ggf. über ein Reduziergetriebe antreibt.On the platform 50 are aggregates, not shown, for. B. a generator operated by an internal combustion engine which drives above the bearing housing 4 (FIG. 1) via intermediate pieces with these flanged electric motors, if necessary via a reduction gear.

Oberhalb der Plattform 50 kann eine nicht dargestellte Plattform angeordnet sein, welche mit den Querschienen 52 vergleichbare Querträger aufweist. An diesen oberen Querträgern können hydraulische Hubeinrichtungen angebracht sein, die über am Motor, bzw. am Lagergehäuse direkt, angreifende Bügel die Vorrichtungen anheben bzw. absenken können.A platform (not shown) can be arranged above the platform 50, which has cross members comparable to the cross rails 52. Hydraulic lifting devices can be attached to these upper cross members, which can raise or lower the devices via brackets which act directly on the motor or on the bearing housing.

Durch diese in Fig. 3 dargestellte Anordnung können eine beliebige Anzahl von Vorrichtungen gemäss Fig. 1 und 2 hintereinander am Gerätewagen angeordnet sein, so dass bei einem Durchgang, auch bei starkem Farbauftrag und schonender Bearbeitung durch jede einzelne der Vorrichtungen, in einem Durchgang jede Markierung beseitigt werden kann.Through this arrangement shown in Fig. 3, any number of devices according to FIGS. 1 and 2 can be arranged one behind the other on the equipment trolley, so that in one pass, even with heavy paint application and gentle processing by each of the devices, each marking in one pass can be eliminated.

Abweichend von der gezeigten Schraubenfeder 19 für die Federanordnung können auch andere Federanordnungen verwandt werden, die beispielsweise auf pneumatischen, hydraulischen, elektrischen oder magnetischen Prinzipien beruhen.In a departure from the coil spring 19 shown for the spring arrangement, other spring arrangements can also be used which are based, for example, on pneumatic, hydraulic, electrical or magnetic principles.
