Abstract

The method involves delivering a marking material (2) for a base layer (31) as a marking material flow (21) from an outlet (16.1). The material for embossed elements (32) is partitioned into small portions from another marking material flow (22) and delivered from another outlet (16.2). Each material flow is conveyed independent of the other material flow at the outlets. Quantities of the material flows are controlled independent of each other. The material flows are individually pumped with a variable pump power for conveying. An independent claim is also included for a device for producing marking lines from pumpable marking material.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Erzeugen von aus einer glatten gleichmäßigen Grundschicht und aus darauf aufgesetzten erhabenen Elementen bestehenden Markierungslinien aus pumpfähigem Markierungsmaterial, wobei das Markierungsmaterial für die Grundschicht als erster, stetiger Markierungsmaterialstrom aus einem ersten Auslass ausgetragen wird und wobei das Markierungsmaterial für die aufgesetzten erhabenen Elemente aus einem zweiten Markierungsmaterialstrom in kleine Portionen aufgeteilt und aus einem zweiten Auslass ausgetragen wird. Außerdem betrifft die Erfindung eine Vorrichtung zum Erzeugen von aus einer glatten gleichmäßigen Grundschicht und aus darauf aufgesetzten erhabenen Elementen bestehenden Markierungslinien.The present invention relates to a method for producing marking lines of pumpable marking material consisting of a smooth uniform base layer and raised elements thereon, wherein the marking material for the base layer is discharged as first, continuous marking material flow from a first outlet and wherein the marking material for the patch raised elements from a second stream of marking material is divided into small portions and discharged from a second outlet. In addition, the invention relates to a device for producing marking lines consisting of a smooth, uniform base layer and of raised elements placed thereon.

Eine Vorrichtung zum Erzeugen von Markierungslinien der vorstehend genannten Art ist aus dem Dokument WO 03/006744 A1 bekannt. Dieses Dokument zeigt in Figur 5 eine Ausführung einer Markierungsvorrichtung mit einem Rotor, dessen Außendurchmesser kleiner ist als der Innendurchmesser einer ihn aufnehmenden und umgebenden Hülse. Dadurch besteht zwischen dem Rotor und der Hülse ein stets für Markierungsmaterial durchgängiger Ringspalt. Im Rotoraußenumfang sind in dessen Umfangsrichtung verteilte Ausnehmungen angebracht. Bei Drehung des Rotors und Fortbewegung der Vorrichtung ergibt sich durch den Ringspalt hindurch ein stetiger Durchfluss von Markierungsmaterial, dem portionsweise ausgetragenes Markierungsmaterial aus den Ausnehmungen überlagert wird. Hierdurch wird eine konstant dicke Grundschicht mit überlagerten erhabenen Elementen ausgetragen und auf eine zu markierende Oberfläche, wie Straße, aufgebracht. Dabei erfolgt der Austrag des Markierungsmaterials durch einen einzigen Materialauslass. Die Dicke der Grundschicht und die Höhe der erhabenen Elemente sind deshalb nicht unabhängig voneinander beeinflussbar, so dass die Möglichkeiten für die Gestaltung der erzeugten Markierungslinie beschränkt sind.An apparatus for producing marking lines of the aforementioned type is known from the document WO 03/006744 A1 known. This document shows in Figure 5 an embodiment of a marking device with a rotor whose outer diameter is smaller than the inner diameter of him receiving and surrounding sleeve. As a result, there is an annular gap which is always continuous for marking material between the rotor and the sleeve. In the rotor outer circumference distributed in the circumferential direction recesses are mounted. Upon rotation of the rotor and locomotion of the device results through the annular gap through a steady flow of marking material, the portionwise discharged marking material from the recesses is superimposed. As a result, a constant thick base layer is discharged with superimposed raised elements and applied to a surface to be marked, such as road. The discharge of the marking material is effected by a single material outlet. The thickness of the base layer and the height of the raised elements are therefore not independent influenced by each other, so that the possibilities for the design of the generated marking line are limited.

Bei einem dem Erfinder aus der einschlägigen Praxis bekannten Verfahren und einer Vorrichtung zu dessen Durchführung wird das Markierungsmaterial aus zwei in Fahrtrichtung der Markierungsvorrichtung hintereinander angeordneten Auslässen ausgetragen und zwar aus dem in Fahrtrichtung ersten Auslass ein der Markierungslinienbreite entsprechendes gleichmäßig dickes Markierungsmaterialband und aus dem zweiten Auslass einzelne kleine Markierungsmaterialportionen. Der zweite Auslass ist dazu mit einer Einrichtung versehen, die den Materialstrom in die kleinen Materialportionen aufteilt, die auf der vorher erzeugten glatten Grundschicht der Markierungslinie die erhabenen Elemente bilden.In a method known to the inventor from the relevant practice and a device for carrying it out, the marking material is discharged from two outlets arranged one behind the other in the direction of travel of the marking device, namely from the first outlet in the direction of travel to a uniform marking strip of the marking line width and single from the second outlet small marking material portions. The second outlet is for this purpose provided with a device which divides the flow of material into the small material portions which form the raised elements on the previously produced smooth base layer of the marking line.

Nachteil des bekannten Verfahrens und der Vorrichtung ist, dass die Förderung des Markierungsmaterials nur durch eine für beide Auslässe gemeinsame Pumpe erfolgt. Dies erschwert die Erzeugung exakt definierter und reproduzierbarer Markierungslinien, da sich eine Verstellung der Fördermenge z. B. durch Verstellung der Pumpendrehzahl stets Durchfluss verändernd auf die Materialströme aus beiden Auslässen auswirkt.Disadvantage of the known method and the device is that the promotion of the marking material is carried out only by a common pump for both outlets. This complicates the generation of precisely defined and reproducible marking lines, since an adjustment of the delivery rate z. B. by adjusting the pump speed always flow changing effect on the material flows from both outlets.

Zwar ist es möglich, ohne Veränderung der Pumpenfördermenge den Materialdurchfluss durch die Auslässe zu beeinflussen und zwar durch Veränderung des Auslassöffnungsquerschnittes. Dies ist aber nur bei dem ersten, die glatte Grundschicht der Markierungslinie erzeugenden Auslass durch Veränderung der Schlitzweite des Auslasses möglich. Bei Veränderung der Schlitzweite ändert sich jedoch auch der Widerstand, den dieser Auslass dem Materialstrom entgegensetzt, und damit auch der Materialdruck stromaufwärts vor diesem Auslass. Eine Druckerhöhung wiederum bewirkt eine oft nicht gewünschte Vergrößerung des Materialdurchflusses durch den zweiten Auslass, so dass sich oft in unzulässiger Weise die Größe der die erhabenen Elemente bildenden auszutragenden Materialportionen ändert.Although it is possible to influence the material flow through the outlets without changing the pump delivery rate and by changing the Auslassöffnungsquerschnittes. However, this is only possible with the first, the smooth base layer of the marking line generating outlet by changing the slot width of the outlet. However, as the slot width changes, so does the resistance that this outlet opposes to the material flow, and thus also the fluid pressure upstream of that outlet. An increase in pressure, in turn, often causes an undesirable increase in the flow of material through the second outlet, so that the size of the portions of material forming the raised elements often changes in an inadmissible manner.

Während des Betriebes einer Markierungsvorrichtung kommt es häufig zu Änderungen der Widerstandsverhältnisse an und vor den Auslässen und in der Regel betreffen solche Änderungen die Auslässe unterschiedlich oder nur einen der beiden Auslässe. Insbesondere bei heißen thermoplastischen Markierungsmaterialien treten diese Änderungen der Widerstandsverhältnisse auf, z. B. infolge von Viskositätsänderungen durch ungleichmäßige Beheizung der Vorrichtung oder infolge von Ablagerungen von separierenden, im Markierungsmaterial enthaltenen Feststoffen. Stets hat eine Änderung der Verhältnisse für den einen Auslass auch Nebenwirkung auf den Materialstrom aus dem anderen Auslass. Dies alles macht die Einstellung im Hinblick auf ein gewünschtes Erscheinungsbild der Markierungslinie und die Beibehaltung eines einmal erreichten gewünschten Erscheinungsbildes schwierig oder in der Praxis sogar fast unmöglich.During operation of a marking device, changes in the resistance ratios often occur and in front of the outlets and, as a rule, such changes affect the outlets differently or only one of the two outlets. Especially when hot thermoplastic marking materials occur these changes in the resistance conditions, z. As a result of changes in viscosity due to uneven heating of the device or as a result of deposits of separating, contained in the marking material solids. A change in the conditions for one outlet always has a side effect on the flow of material from the other outlet. All this makes the adjustment difficult in view of a desired appearance of the marking line and the maintenance of a desired appearance once achieved, or even almost impossible in practice.

Durch die Erfindung soll der Mangel der bekannten Verfahren und Vorrichtungen beseitigt werden und es sollen ein Verfahren und eine Vorrichtung geschaffen werden, mit denen die Einstellung eines gewünschten Erscheinungsbildes der Markierungslinie und die Beibehaltung eines einmal erreichten gewünschten Erscheinungsbildes vereinfacht oder überhaupt erst ermöglicht werden.The invention seeks to remedy the deficiency of the known methods and apparatuses and to provide a method and an apparatus with which the setting of a desired appearance of the marking line and the maintenance of a desired appearance once achieved can be simplified or even made possible.

Die Lösung des Teils der Aufgabe, der das Verfahren betrifft, gelingt erfindungsgemäß mit einem Verfahren der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1.The solution of the part of the object, which relates to the method, according to the invention succeeds with a method of the type mentioned above with the characterizing features of patent claim 1.

Erfindungsgemäß ist vorgesehen, dass jeder Markierungsmaterialstrom unabhängig vom jeweils anderen Markierungsmaterialstrom zu seinem Auslass gefördert wird. Dadurch wird erreicht, dass eine Änderung der Widerstandsverhältnisse vor und in einem Auslass und damit eine Änderung des Druckes vor einem Auslass keinen Einfluss auf die Druckverhältnisse vor dem anderen Auslass hat und somit auch keinen Einfluss auf die Größe des Materialstromes und auf das Erscheinungsbild der Markierungslinie hat.According to the invention, it is provided that each marking material flow is conveyed to its outlet independently of the respective other marking material flow. This ensures that a change in the resistance ratios before and in one outlet and thus a change in the pressure before one outlet has no influence on the pressure conditions before the other outlet and thus has no effect on the size of the material flow and on the appearance of the marking line ,

In einer weiteren Ausgestaltung der Erfindung werden die einzelnen Markierungsmaterialströme unabhängig voneinander in ihrer Größe gesteuert. Dies ermöglicht es, unabhängig voneinander die Größe der Materialströme durch die beiden Auslässe einzustellen und/oder bei Änderung der Widerstandsverhältnisse in der Auslassöffnung bzw. stromaufwärts vor der Auslassöffnung den Materialstrom sofort entsprechend dem gewünschten Erscheinungsbild der Markierungslinie korrigierend zu verändern.In a further embodiment of the invention, the individual marking material streams are independently controlled in size. This makes it possible to independently adjust the size of the material flows through the two outlets and / or to change the material flow immediately corresponding to the desired appearance of the marking line when the resistance conditions in the outlet opening or upstream of the outlet opening change.

Für das Verfahren ist weiter bevorzugt vorgesehen, dass zu ihrer Förderung die Markierungsmaterialströme einzeln mit jeweils veränderbarer Pumpleistung gepumpt werden. Auf diese Weise lassen sich mit technisch wenig Aufwand die Markierungsmaterialströme in ihrer Größe auf ein gewünschtes Maß einstellen und bei Bedarf leicht korrigieren.For the method, it is further preferred for the marking material streams to be pumped individually, each with variable pumping power, in order to be conveyed. In this way, the marking material streams can be adjusted in size to a desired level with little technical effort and easily corrected if necessary.

Die Lösung des zweiten Teils der Aufgabe, betreffend die Vorrichtung, gelingt erfindungsgemäß mit einer Vorrichtung zum Erzeugen von aus einer glatten gleichmäßigen Grundschicht und aus darauf aufgesetzten erhabenen Elementen bestehenden Markierungslinien aus pumpfähigem Markierungsmaterial, wobei das Markierungsmaterial für die Grundschicht als erster, stetiger Markierungsmaterialstrom aus einem ersten entsprechend geformten Auslass austragbar ist und wobei das Markierungsmaterial für die aufgesetzten erhabenen Elemente aus einem mit einer einen zweiten Markierungsmaterialstrom in kleine Portionen aufteilenden Aufteileinrichtung kombinierten zweiten Auslass austragbar ist, welche dadurch gekennzeichnet ist, dass jeder Markierungsmaterialstrom unabhängig vom jeweils anderen Markierungsmaterialstrom zu seinem Auslass förderbar ist.The solution of the second part of the object, concerning the device, according to the invention succeeds with a device for producing from a smooth uniform base layer and placed thereon raised elements marking lines of pumpable marking material, wherein the marking material for the base layer as a first, continuous marking material flow of a wherein the marker material for the attached raised elements is dischargeable from a second outlet combined with a second marker stream in small portions, characterized in that each marker stream is independently deliverable to its outlet from the other marker stream is.

Mit dieser Vorrichtung kann das erfindungsgemäße Verfahren mit geringem technischem Aufwand ausgeführt werden und es lassen sich Markierungslinien in der vorstehend genannten Art mit hoher, gleichbleibender Qualität und guter Reproduzierbarkeit herstellen.With this device, the inventive method can be carried out with little technical effort and it can be produced marking lines in the aforementioned manner with high, consistent quality and good reproducibility.

Die Vorrichtung 1 ist an oder auf einem Fahrzeug angeordnet, um sie in der Richtung R relativ zu einer zum markierenden Oberfläche 30, wie Straße, zu bewegen. Die Vorrichtung 1 ist in einem schematischen Vertikalschnitt gezeigt, wobei das zugehörige Fahrzeug nicht dargestellt ist. FIG. 1 1 shows a device 1 for producing marking lines 3, which consist of a uniformly thick base layer 31 with raised elements 32 distributed thereon. The device 1 is disposed on or on a vehicle to move in the direction R relative to a marking surface 30, such as a road. The device 1 is shown in a schematic vertical section, wherein the associated vehicle is not shown.

In einem Markierungsmaterialvorratsbehälter 10 befindet sich ein Vorrat an Markierungsmaterial 2, zum Beispiel ein thermoplastisches Markierungsmaterial. Vom Vorratsbehälter 10 führt eine Pumpenzuleitung 11 zu den Einlässen von zwei Pumpen 12.1 und 12.2. Die beiden Pumpen 12.1 und 12.2 sind hier als Schneckenpumpen ausgeführt, können aber auch von anderer geeigneter Konstruktion sein. Jede Pumpe 12.1 und 12.2 besitzt einen eigenen Pumpenantrieb 13.1 und 13.2. Jeder Pumpenantrieb 13.1 und 13.2 besteht aus einem für sich steuerbaren Motor, so dass die Pumpenleistung jeder Pumpe 12.1 und 12.2 individuell eingestellt und bei Bedarf geändert werden kann. Auslassseitig führt von jeder Pumpe 12.1 und 12.2 eine Förderleitung 14.1, 14.2 zu zwei Materialkammern 15.1 und 15.2.In a marking material reservoir 10 is a supply of marking material 2, for example a thermoplastic marking material. From the reservoir 10, a pump supply line 11 leads to the inlets of two pumps 12.1 and 12.2. The two pumps 12.1 and 12.2 are designed here as worm pumps, but may also be of other suitable construction. Each pump 12.1 and 12.2 has its own pump drive 13.1 and 13.2. Each pump drive 13.1 and 13.2 consists of a self-controllable motor, so that the pump power of each pump 12.1 and 12.2 can be set individually and changed if necessary. On the outlet side of each pump leads 12.1 and 12.2 a delivery line 14.1, 14.2 to two material chambers 15.1 and 15.2.

Die erste Materialkammer 15.1 liegt in Bewegungsrichtung R vorne und dient zur Erzeugung der Grundschicht 31 der Markierungslinie 3. Hierzu besitzt die erste Materialkammer 15.1 an der Vorderkante ihres Bodens einen ersten Auslass 16.1, der schlitzartig ausgebildet ist. Die Länge des Schlitzes entspricht dabei der Breite der zu erzeugenden Markierungslinie 3. Die Weite des Schlitzes entspricht der Dicke der Grundschicht 31. Mittels eines Schlitzverschlusses 17 kann die Weite des den ersten Auslass bildenden Schlitzes 16.1 und damit die Dicke der Grundschicht 31 bedarfsgerecht eingestellt werden. Hierzu umfasst der Schlitzverschluss 17 eine bewegliche Schlitzbegrenzung, die von einer Kolben-Zylinder-Einheit 17.1 über einen Hebel verstellbar ist. Mittels eines Anschlages 17.2, der den Bewegungsweg des Kolbens im Zylinder begrenzt, kann eine maximale Schlitzweite festgelegt werden. In umgekehrter Richtung kann der erste Auslass 16.1 durch den Schlitzverschluss 17 vollständig verschlossen werden.The first material chamber 15.1 lies in the direction of movement R at the front and serves to produce the base layer 31 of the marking line 3. For this purpose, the first material chamber 15.1 at the front edge of its bottom has a first outlet 16.1, which is slit-like. The width of the slot corresponds to the width of the marking line 3 to be produced. The width of the slot corresponds to the thickness of the base layer 31. By means of a slot closure 17, the width of the slot 16.1 forming the first outlet and thus the thickness of the base layer 31 can be adjusted as required. For this purpose, the slot closure 17 comprises a movable slot boundary, which is adjustable by a piston-cylinder unit 17.1 via a lever. By means of a stop 17.2, which limits the path of movement of the piston in the cylinder, a maximum slot width can be set. In the reverse direction, the first outlet 16.1 can be completely closed by the slot closure 17.

Mittig im Boden der hinter der ersten Materialkammer 15.1 liegenden zweiten Materialkammer 15.2 befindet sich ein zweiter Auslass 16.2, durch den die erhabenen Elemente 32 der Markierungslinie 3 ausgebracht werden. Im Inneren der Materialkammer 15.2 ist eine Trommel 18' angeordnet, die um eine horizontal und quer zur Bewegungsrichtung R verlaufende Achse drehbar ist, wie durch den Pfeil in der Trommel 18' angedeutet ist. Die Trommel 18' besitzt in Umfangsrichtung und/oder in ihrer Längsrichtung abwechselnd Bereiche, die für das Markierungsmaterial 2 durchlässig oder undurchlässig sind. Im unteren Bereich ihres Außenumfangs wirkt die Trommel 18' dichtend mit zwei Kanten 19.1 und 19.2 zusammen, die zwischen sich den zweiten Auslass 16.2, ebenfalls in Form eines Schlitzes, bilden. Dabei bildet die Kante 19.1 einen Teil eines Auf-/Zu-Schiebers 19, mit dem der zweite Auslass 16.2 wahlweise geöffnet und geschlossen werden kann.Located centrally in the bottom of the second material chamber 15.2 located behind the first material chamber 15.1 is a second outlet 16.2, through which the raised elements 32 of the marking line 3 are deployed. Inside the material chamber 15.2, a drum 18 'is arranged, which is a horizontal and transverse to the Moving direction R axis is rotatable, as indicated by the arrow in the drum 18 '. The drum 18 'has in the circumferential direction and / or in its longitudinal direction alternately areas which are permeable or impermeable to the marking material 2. In the lower part of its outer periphery, the drum 18 'sealingly cooperates with two edges 19.1 and 19.2, which form between them the second outlet 16.2, also in the form of a slot. In this case, the edge 19.1 forms part of an open / close slide 19 with which the second outlet 16.2 can optionally be opened and closed.

Im Betrieb der Vorrichtung 1 wird diese in Richtung des Bewegungspfeils R relativ zu der zu markierenden Oberfläche 30 bewegt. Mittels der beiden Pumpen 12.1 und 12.2 wird Markierungsmaterial 2 aus dem Markierungsmaterialvorratsbehälter 10 in die Förderleitungen 14.1 und 14.2 gefördert. Dabei erfolgt die Förderung durch die beiden Pumpen 12.1 und 12.2 unabhängig voneinander. Durch die beiden zugeordneten Förderleitungen 14.1 und 14.2 gelangt das Markierungsmaterial 2 in die beiden Materialkammern 15.1 und 15.2.During operation of the device 1, it is moved in the direction of the movement arrow R relative to the surface 30 to be marked. By means of the two pumps 12.1 and 12.2 marking material 2 is conveyed from the marking material reservoir 10 in the delivery lines 14.1 and 14.2. The promotion is carried out by the two pumps 12.1 and 12.2 independently. Due to the two associated delivery lines 14.1 and 14.2, the marking material 2 enters the two material chambers 15.1 and 15.2.

Aus der ersten Materialkammern 15.1 wird das Markierungsmaterial 2 in Form eines ersten kontinuierlichen Markierungsmaterialstroms 21 ausgebracht und bildet auf der zu markierenden Oberfläche 30 die gleichmäßige, glatte Grundschicht 31.From the first material chambers 15.1, the marking material 2 is applied in the form of a first continuous stream of marking material 21 and forms the uniform, smooth base layer 31 on the surface 30 to be marked.

Aus der zweiten Materialkammer 15.2 wird infolge der Drehung der Trommel 18' das Markierungsmaterial 2 in Form eines zweiten, einzelne kleine Materialportionen bildenden Markierungsmaterialstroms 23 ausgebracht, wodurch auf die Grundschicht 31 die erhabenen Elemente 32 aufgebracht werden.From the second material chamber 15.2, as a result of the rotation of the drum 18 ', the marking material 2 is applied in the form of a second marking material stream 23 forming individual small material portions, whereby the raised elements 32 are applied to the base layer 31.

Wenn eine glatte Markierungslinie ohne erhabene Elemente erzeugt werden soll, wird der Auf-/Zu-Schieber 19 in Schließstellung gebracht und ein Markierungsmaterialaustrag erfolgt nur noch durch den ersten Auslass 16.1. Wenn eine nur aus erhabenen Elementen bestehende Markierungslinie erzeugt werden soll, wird der Schlitzverschluss 17 in Schließstellung gebracht und ein Markierungsmaterialaustrag erfolgt nur noch portionsweise durch den zweiten Auslass 16.2.If a smooth marking line is to be produced without raised elements, the open / close slide 19 is brought into the closed position and a marking material discharge takes place only through the first outlet 16.1. If a marking line consisting only of raised elements is to be produced, the slot closure 17 is brought into the closed position and a marking material discharge takes place only in portions through the second outlet 16.2.

Figur 2 der Zeichnung zeigt in einer Draufsicht einen Abschnitt der von der Vorrichtung 1 gemäß Figur 1 erzeugten Markierungslinie 3. Im vorderen Bereich, das heißt in Figur 2 rechts, ist zunächst nur die gleichmäßig dicke, glatte Grundschicht 31 ausgebracht. Im weiter hinten liegenden Teil, das heißt in Figur 2 links, sind auf die Grundschicht 31 auch die erhabenen Elemente 32 aufgebracht, wodurch die Markierungslinie 3 auf der zu markierenden Oberfläche 30 gebildet wird. FIG. 2 The drawing shows a plan view of a portion of the device 1 according to FIG. 1 generated marking line 3. In the front area, that is in FIG. 2 on the right, initially only the uniformly thick, smooth base layer 31 is applied. In the further back, that is in FIG. 2 On the left, the raised elements 32 are also applied to the base layer 31, whereby the marking line 3 is formed on the surface 30 to be marked.
