Description

Die Erfindung bezieht sich auf einen Straßenfertiger der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a paver of the type explained in the preamble of claim 1.

Ein derartiger Straßenfertiger ist beispielsweise aus dem DE-U 92 03 867 bekannt. Die bekannten Straßenfertiger haben im in Fahrtrichtung vorderen Bereich einen Bunker, in dem Einhaumaterial zwischengelagert wird. Der Bunker wird während der Arbeit des Straßenfertigers von einem LKW beschickt und hat ein ausreichendes Fassungsvermögen, um die ungehinderte Weiterarheit des Straßenfertigers zwischen zwei Beschickungsvorgängen zu garantieren. Zum Beschicken des Bunkers fährt der LKW rückwärts an den vorwärtsfahrenden Straßenfertiger heran und entleert seine Ladefläche in den Bunker, während der Straßenfertiger den LKW schiebt. Diese Art der Beschikkung erfordert jedoch erfahrenes Personal und eine abgestimmte Arbeitsweise zwischen dem Fahrer des Straßenfertigers und dem Fahrer des LKWs. Dies ist jedoch nicht immer gewährleistet.Such a paver is known for example from DE-U 92 03 867. The well-known road pavers have a bunker in the front area in the direction of travel, in which the ply material is temporarily stored. The bunker is loaded by a truck while the paver is working and has sufficient capacity to guarantee the paver's unhindered continuity between two loading processes. To load the bunker, the truck drives backwards to the forwarding paver and empties its loading area into the bunker while the paver is pushing the truck. However, this type of charging requires experienced personnel and a coordinated way of working between the driver of the paver and the driver of the truck. However, this is not always guaranteed.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Straßenfertiger der genannten Art so auszugestalten, daß die Beschickung des Straßenfertigers mit Einbaumaterial auch von ungeübten Personen sicher und in abgestimmten Vorgehensweisen durchgeführt werden kann.The invention is therefore based on the object of designing a paver of the type mentioned in such a way that loading of the paver with paving material can also be carried out safely by inexperienced persons and in coordinated procedures.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.

Durch die erfindungsgemäße Einrichtung zum Überwachung und Anzeigen von Parametern der Beschickung mit Einbaumaterial werden subjektive Eindrücke des Bedienungspersonals eliminiert und dem Bedienungspersonal genaue und exakte Anweisungen bzw. Befehle für jeweils ganz bestimmte vom Bedienungspersonal vorzunehmende Handlungen entsprechend der tatsächlich festgestellten Parameter gegeben. Damit wird erreicht, daß der Straßenfertiger mit Einbaumaterial beschickt werden kann, ohne daß eine dritte Person die Versorgungseinheit und den Straßenfertiger koordinieren muß und ohne daß die Gefahr von Mißverständnissen und daraus resultierendem Fehlverhalten besteht.The inventive device for monitoring and displaying parameters of the loading with installation material eliminates subjective impressions of the operating personnel and gives the operating personnel precise and exact instructions or commands for very specific actions to be carried out by the operating personnel in accordance with the parameters actually determined. This ensures that the paver can be loaded with paving material without a third person having to coordinate the supply unit and the paver and without the risk of misunderstandings and the resulting misconduct.

Zwar ist es bei Straßenfertigern bekannt, beispielsweise aus der DE-A-39 11 229, der EP-A-562 586 oder der EP-A-279 795 bestimmte Parameter von Sensoren überwachen zu lassen. Die von den Sensoren gelieferten Signale werden jedoch zum Steuern maschineninterner Betriebsabläufe verwendet, also z.B. für die Zuschaltung des Vorderradantriebs bei vollständig beladener Mulde in der DE-A-39 11 229, für die Steuerung der Länge des Überstandes einer Abstützvorrichtung zum Schieben der mobilen Versorgungseinheit in Abhängigkeit von Form und Abmessung der Versorgungseinheit in der EP-A-562 586 oder für die Steuerung der Verteilung des Einbaumaterials in Abhängigkeit von der Höhe des von der Schnecke vorgelegten Materials in der EP-A-279 795. Eine Anzeige der Signale und eine Umwandlung in Befehle ist nicht vorgesehen. Andererseits wird die Anzeigevorrichtung in Form eines Monitors des DE-U-93 17 225 zur Darstellung von Videobildern von Kameras rund um den Fertiger bzw. zur Darstellung üblicher Betriebsdaten, wie beispielsweise die Fahrzeuggeschwindigkeit, und nicht zur Anzeige von Parametern der Beschickung mit Einbaumaterial durch eine externe, mobile Versorgungseinheit verwendet.It is known in road pavers, for example, to have certain parameters monitored by sensors from DE-A-39 11 229, EP-A-562 586 or EP-A-279 795. However, the signals supplied by the sensors are used to control internal machine operations, e.g. for the connection of the front wheel drive when the trough is fully loaded in DE-A-39 11 229, for controlling the length of the overhang of a supporting device for pushing the mobile supply unit depending on the shape and dimensions of the supply unit in EP-A-562 586 or for controlling the distribution of the paving material depending on the height of the material presented by the screw in EP-A-279 795. A display of the signals and a conversion into commands is not provided. On the other hand, the display device in the form of a monitor of DE-U-93 17 225 for displaying video images from cameras around the paver or for displaying conventional operating data, such as the vehicle speed, and not for displaying parameters of the loading with paving material by a external, mobile supply unit used.

Die Ansprüche 2 bis 5 beschreiben verschiedene Fühler, die alternativ oder gemeinsam in der erfindungsgemäßen Einrichtung zum Überwachen und Anzeigen vorgesehen werden können.Claims 2 to 5 describe various sensors which can alternatively or jointly be provided in the device according to the invention for monitoring and displaying.

Zusätzlich kann auch der in Anspruch 6 beschriebene Fühler vorgesehen sein.In addition, the sensor described in claim 6 can also be provided.

Zweckmäßigerweise enthält die Anzeigevorrichtung gemäß Anspruch 7 eine Anzeigeeinheit für die Bedienperson des Straßenfertigers und gemäß Anspruch 8 eine Anzeigeeinheit, die an die Versorgungseinheit gerichtet ist.Advantageously, the display device according to claim 7 contains a display unit for the operator of the paver and according to claim 8 a display unit which is directed to the supply unit.

Gemäß den Ansprüchen 9 und 10 kann die an die Versorgungseinheit gerichtete Anzeigeeinheit eine elektronische Anzeigetafel und/oder ein Sender sein, mit dem die Parameter, zweckmäßigerweise umgewandelt in entsprechende Befehle, einem geeigneten Empfänger in der Versorgungseinheit übertragen werden.According to claims 9 and 10, the display unit directed to the supply unit can be an electronic display board and / or a transmitter with which the parameters, expediently converted into corresponding commands, are transmitted to a suitable receiver in the supply unit.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 eine schematische Darstellung eines erfindungsgemäßen Straßenfertigers, und
  • Fig. 2a - 2g Darstellungen von Befehlen auf einer Anzeigetafel am Straßenfertiger nach Fig. 1.
An embodiment of the invention is explained below with reference to the drawings. Show it:
  • Fig. 1 is a schematic representation of a paver according to the invention, and
  • 2a-2g representations of commands on a display panel on the paver of FIG. 1.

Fig. 1 zeigt einen nur schematisch angedeuteten Straßenfertiger 1, der einen in einem Fahrerhaus 2 angeordneten Bedienungsbereich 3, den üblichen, nicht gezeichneten Fahrantrieb mit wenigstens einer angetriebenen Achse 4, eine in Fahrtrichtung A nachgeschleppte Einbaubohle 5, der von einem Einbauförderer Einbaumaterial vorgelegt wird, wobei der Einbauförderer eine der üblichen Schnekkenförderer 6 und nicht gezeichnete, ebenfalls übliche Kratzerbänder im Inneren des Straßenfertigers aufweist. Die Kratzerbänder des Einbauförderers fördern Einbaumaterial aus einem Bunker 7, der in Fahrtrichtung A vorn am Straßenfertiger 1 angeordnet ist. Der Bunker 7 hat, wie ebenfalls üblich aber nicht gezeichnet, abklappbare Bunkerwände zum Freilegen einer Einfüllöffnung 8. An der in Fahrtrichtung A vorderen Seite des Straßenfertigers 1 stehen Addruckrollen 9 vor, mit denen der Straßenfertiger 1 eine externe, mobile Versorgungseinheit, bevorzugt einen LKW 10 mit nach hinten kippbarer Ladefläche, während seiner Arbeit beim Einbau von Staßenbaumaterial vor sich her schieben kann.1 shows a road paver 1, indicated only schematically, which has an operating area 3 arranged in a driver's cab 2, the usual drive drive (not shown) with at least one driven axle 4, a screed 5 dragged in the direction of travel A, which is provided by paving material from a paving conveyor, wherein the built-in conveyor has one of the usual screw conveyors 6 and not shown, also usual scraper belts inside the paver. The scraper belts of the paving conveyor convey paving material from a bunker 7, which is arranged at the front of the paver 1 in the direction of travel A. The bunker 7, as is also common but not shown, has bunker walls that can be folded down to expose a filling opening 8. On the front side of the paver 1 in the direction of travel A there are pressure rollers 9 with which the paver 1 has an external, mobile supply unit, preferably a truck 10 with after rear tilting loading area, during his work when paving road building material in front of him.

Der Straßenfertiger 1 ist mit einer Einrichtung 11 zum Überwachen und Anzeigen von für eine Beschickung mit Einbaumaterial relevanten Betriebsparametern des Straßenfertigers versehen. Die Einrichtung 11 enthält wenigstens einen Abstandssensor 12, der in Fahrtrichtung A nach vorn gerichtet und in der Läge ist, den Abstand zum hinteren Ende des LKW 10 festzustellen. Die Einrichtung 11 enthält weiterhin wenigstens einen Sensor 13, mit dem der Befüllungsgrad bzw. der Füllstand im Bunker 7 festzustellen ist. Die Einrichtung 11 enthält weiterhin wenigstens einen Sensor 14, der die Drehmomentaufnahme am Antriebemotor feststellt. Die Einrichtung 11 enthält einen weiteren Sensor 15, mit dem festgestellt werden kann, ob die Bunkerwände auf- oder abgeklappt, die Einfüllöffnung 8 somit offen oder geschlossen ist. Schließlich ist am Straßenfertiger 1 ein weiterer Sensor 16 vorgesehen, mit dem der Füllstand im Schneckenraum der Förderschnecke 6 festgestellt, d.h. bestimmt werden kann, ob der Schnecke 6 genügend Einbaumaterial zum Beschicken der Einbaubohle 5 mit der vorbestimmten Menge an Einbaumaterial zugeführt werden kann.The road paver 1 is provided with a device 11 for monitoring and displaying operating parameters of the road paver which are relevant for loading with paving material. The device 11 contains at least one distance sensor 12, which is directed forward in the direction of travel A and is able to determine the distance to the rear end of the truck 10. The device 11 also contains at least one sensor 13 with which the degree of filling or the fill level in the bunker 7 can be determined. The device 11 further contains at least one sensor 14 which detects the torque absorption on the drive motor. The device 11 contains a further sensor 15, with which it can be determined whether the bunker walls are opened or closed, the filling opening 8 is thus open or closed. Finally, a further sensor 16 is provided on the paver 1 with which the fill level in the screw chamber of the screw conveyor 6 is determined, i.e. It can be determined whether the auger 6 can be supplied with enough paving material to load the screed 5 with the predetermined amount of paving material.

Im Bedienungsbereich 3 des Fahrerhauses 2 des Straßenfertigers 1, gut sichtbar für den Fahrer des LKW 10, ist eine elektronische Anzeigetafel 17 angeordnet. Die Anzeigetafel ist am Fahrerhaus 2 in einer Höhe und einer Lage befestigt und bevorzugt ausklappbar, so daß sie auch vom Fahrer des Straßenfertigers 1 ohne weiteres einsehbar ist. Mit der Anzeigetafel 17 ist eine Datenverarbeitung verbunden, die die Signale von allen Sensoren 12, 13, 14, 15, 16 erhält und sie in Befehle umwandelt, die zweckmäßigerweise in Form von Piktogrammen oder Analoganzeigen auf der Anzeigetafel 17 erscheinen. Darüber hinaus kann die Datenverarbeitungseinrichtung auch zum direkten Steuern verschiedener Betriebszustände am Straßenfertiger 1 verwendet werden, sie kann beispielsweise den Befehl zur automatischen Schließung der Bunkerwände geben, wenn der Füllstandssensor 13 einen vollständig gefüllten Bunker 7 signalisiert, oder sie kann beispielsweise die Einbaubarbeiten stoppen, wenn der Füllstandssensor 16 signalisiert, daß im Schneckenraum zu wenig Material für einen Einbau des Straßenbaumaterials in vorgegebener Stärke vorhanden ist.An electronic display panel 17 is arranged in the operating area 3 of the driver's cab 2 of the road finisher 1, which is clearly visible to the driver of the truck 10. The display panel is attached to the cab 2 at a height and position and can preferably be folded out, so that it can also be easily viewed by the driver of the paver 1. A data processing unit is connected to the display panel 17, which receives the signals from all sensors 12, 13, 14, 15, 16 and converts them into commands which expediently appear on the display panel 17 in the form of pictograms or analog displays. In addition, the data processing device can also be used for direct control of various operating states on the road paver 1, it can, for example, give the command to automatically close the bunker walls when the level sensor 13 signals a completely filled bunker 7, or it can stop the paving work, for example Level sensor 16 signals that there is too little material in the screw chamber for the road building material to be installed in a predetermined thickness.

Die Anzeigetafel 17 hat, wie Fig. 2 zeigt, drei Anzeigefelder 17a, 17b und 17c. Die Wirkungsweise der Einrichtung 11 und die Anzeige beim Beschicken des Bunkers 7 mit Straßenbaumaterial aus dem LKW 10 wird nachfolgend anhand der Darstellungen der entsprechenden Anzeigen auf der Anzeigetafel 17 näher erläutert. Im Anzeigenfeld 17a erscheinen die Antriebs- und Bewegungszustände von LKW und Straßenfertiger. Im Anzeigenfeld 17b erscheint zum einen eine Analoganzeige des Abstandes zwischen dem Straßenfertiger 1 und dem LKW 10 und zum zweiten Befehle zum Bewegen der Ladefläche des LKWs 10. Das Anzeigenfeld 17c beschreibt den Ist-Zustand von LKW 10 und Straßenfertiger 1.As shown in FIG. 2, the display panel 17 has three display fields 17a, 17b and 17c. The mode of operation of the device 11 and the display when loading the bunker 7 with road building material from the truck 10 is explained in more detail below on the basis of the representations of the corresponding displays on the display panel 17. The drive and movement states of trucks and road pavers appear in display field 17a. The display field 17b shows, on the one hand, an analog display of the distance between the paver 1 and the truck 10 and, secondly, commands for moving the loading area of the truck 10. The display field 17c describes the actual state of the truck 10 and the paver 1.

Vor Beginn des Beschickungsvorganges hat der Füllstandssensor 13 festgestellt, daß der Füllstand im Bunker 7 unter einen vorbestimmten Wert abgesunken ist, und hat die Bunkerwände abgeklappt, so daß die Befüllöffnung 8 des Bunkers 7 offen ist. Der LKW 10 nähert sich in langsamer Rückwärtsfahrt dem sich in Fahrtrichtung A bewegenden und Straßenbaumaterial einbauenden Straßenfertiger 1. Die Rückwärtsfahrt des LKW 10 ist durch ein Dreieck mit nach rechts gerichteter Spitze im ersten Feld 17a der Anzeigetafel 17 angezeigt, während im zweiten Feld 17b der vom Abstandssensor 12 festgestellte Abstand zwischen dem Straßenfertiger 1 und dem LKW 10 in Analoganzeige erscheint. Das dritte Feld 17c stellt den Ist-Zustand in Piktogrammform dar. Der LKW 10 und der Straßenfertiger 1 nähern sich weiter aneinander an, wobei der abnehmende Abstand, wie Fig. 2b zeigt, im zweiten Feld 17b angezeigt wird. Dann wird im zweiten Feld 17b, Fig. 2c, dem LKW "STOP" signalisiert. Der LKW-Fahrer löst gegebenenfalls seine Bremse und der Straßenfertiger 1 kommt mit seinen Abdruckrollen 9 mit dem LKW 10 in Eingriff und schiebt den LKW 10 vor sich her, während nach wie vor Straßenbaumaterial eingebaut wird. Dieses Schieben wird vom Sensor 14 durch einen Drehmomentanstieg am Fahrantrieb festgestellt und im ersten Feld 17a durch zwei mit ihren Basislinien aufeinander zu weisende Dreiecke dargestellt. Gleichzeitig ergeht durch ein Dreieck mit nach oben gerichteter Spitze im zweiten Anzeigefeld 17b an den LKW-Fahrer der Befehl, die Ladefläche zu kippen. Gleichzeitig wird im dritten Anzeigefeld 17c der Ist-Zustand, d.h. die in den Bunker 7 eingekippte Ladefläche in Piktogrammform dargestellt (Fig. 2d). Ist die Ladefläche gekippt, so daß Einbaumaterial in den Bunker 7 hineinrutscht, so erscheinen auf dem zweiten Anzeigefeld 17b (Fig. 2e) zwei schräggestellte, mit ihren Basisflächen zueinander gerichtete Dreiecke, die dem LKW-Fahrer signalisieren, daß er die Ladefläche in gekippter Stellung halten soll. Dieser Zustand hält so lange an, bis der Füllstandssensor 13 die vollständige Befüllung des Bunkers 7 meldet. Dann erscheint auf dem zweiten Anzeigefeld 17b der Anzeigetafel 17 (Fig. 2f) der Befehl an den LKW-Fahrer, daß er die Ladefläche senken soll, in Form eines einzelnen Dreiecks mit schräg nach unten gerichteter Spitze. Anschließend erscheint im ersten Anzeigefeld 17a (Fig. 2g) der Befehl, daß der LKW 10 nach vorn vom Straßenfertiger 1 wegfahren soll, in Form eines Dreiecks mit nach links gerichteter Spitze. Damit ist der Beschickungsvorgang des Bunkers 7 beendet und die Bunkerwände werden selbsttätig wieder hochgeklappt, sobald der Abstandssensor 12 meldet, daß der LKW 10 mit seiner Ladefläche aus dem Bereich des Bunkers 7 nach vorn vorgefahren ist.Before the loading process begins, the fill level sensor 13 has determined that the fill level in the bunker 7 has dropped below a predetermined value and has folded down the bunker walls so that the filling opening 8 of the bunker 7 is open. The truck 10 approaches the paver 1 moving in the direction of travel A and incorporating road construction material in slow reverse travel. The backward travel of the truck 10 is indicated by a triangle with a point pointing to the right in the first field 17a of the display panel 17, while in the second field 17b that of the Distance sensor 12 detected distance between the paver 1 and the truck 10 appears in an analog display. The third field 17c represents the current state in the form of a pictogram. The truck 10 and the paver 1 move closer together, the decreasing distance, as shown in FIG. 2b, being displayed in the second field 17b. Then the truck is signaled "STOP" in the second field 17b, FIG. 2c. The truck driver may release his brake and the paver 1 comes into engagement with the truck 10 with his impression rollers 9 and pushes the truck 10 in front of him while road building material is still being installed. This pushing is detected by the sensor 14 through an increase in torque on the travel drive and is represented in the first field 17a by two triangles with their base lines pointing towards one another. At the same time, a triangle with the tip pointing upward gives the command to the truck driver to tilt the loading area in the second display field 17b. At the same time, the actual state, ie the loading area tipped into the bunker 7, is shown in the form of a pictogram in the third display field 17c (FIG. 2d). If the loading area is tilted so that paving material slips into the bunker 7, then two oblique triangles with their base surfaces facing each other appear on the second display field 17b (FIG. 2e), which signal to the truck driver that he is loading the loading area in the tilted position should hold. This state continues until the fill level sensor 13 reports that the bunker 7 has been completely filled. Then on the second display field 17b of the display panel 17 (FIG. 2f) the command to the truck driver that he should lower the loading area appears in the form of a single triangle with the tip pointing obliquely downwards. The command that then appears in the first display field 17a (FIG. 2g) the truck 10 is to move away from the paver 1 in the form of a triangle with the tip pointing to the left. This completes the loading process of the bunker 7 and the bunker walls are automatically folded up again as soon as the distance sensor 12 reports that the truck 10 has moved forward with its loading area out of the area of the bunker 7.

Anstelle der Anzeige auf einer nur am Straßenfertiger angeordneten Anzeigetafel, kann die Einrichtung 11 auch einen nicht gezeichneten Sender aufweisen, der die ermittelten Daten bzw. die daraus gewonnenen Befehle schnurlos an einen geeigneten Empfänger im Fahrerhaus des LKW überträgt.Instead of the display on a display panel arranged only on the paver, the device 11 can also have a transmitter, not shown, which transmits the determined data or the commands obtained therefrom wirelessly to a suitable receiver in the cab of the truck.

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann für den Fertigerfahrer eine eigene Anzeigeeinheit, beispielsweise auf seinem Bedienpult, vorgesehen werden. Zur Ermittlung der Befehle für den Beschickungsvorgang können, je nach Baurt und Ausstattung des Straßenfertigers, weitere Signale von weiteren Sensoren herangezogen werden.In a modification of the exemplary embodiment described and drawn, a separate display unit can be provided for the paver operator, for example on his control panel. To determine the commands for the loading process, further signals from other sensors can be used, depending on the construction machine's construction and equipment.
