Description

Die Erfindung betrifft einen Straßenfertiger gemäß Oberbegriff des Patentanspruches 1 sowie ein Verfahren gemäß Oberbegriff des Patentanspruches 6.The invention relates to a paver according to the preamble of claim 1 and a method according to the preamble of claim. 6

Moderne, auf dem Markt verwendete Straßenfertiger weisen ein Ventilationssystem mit einem ein- und abschaltbaren, ungeregelten Lüfter auf, um Dämpfe und Aerosole beim Einbau, beispielsweise von Walzasphalt im Straßenbau, zu sammeln und so abzuführen, dass Fertiger- bzw. Einbaubohlen-Bediener komfortablere Arbeitsbedingungen haben, und auch die direkte Umgebung auf der Baustelle durch das gezielte Abführen solcher Reizstoffe entlastet wird. Bestimmte Maschinenfunktionen und Betriebsarten des Straßenfertigers und der Einbaubohle sind nun grundsätzlich auf das jeweilige Mischgut abgestimmt. Walzasphalt, beispielsweise im Straßenbau, wird mit einem mit Bitumen gebundenen Mischgut mit definierter Einbautemperatur üblicherweise weit über 100°C verbaut, wobei auch die Heizeinrichtungen der Einbaubohle entsprechend leistungsstark betrieben werden. Dadurch werden Dämpfe und Aerosole beispielsweise aus dem Bitumen verstärkt freigesetzt. Hingegen wird bei hydraulisch gebundenen Mischgütern kaum Dampf und Aerosol freigesetzt, auch weil die Heizeinrichtungen nicht oder nur moderat betrieben sind. Ähnliches gilt für Beton-Mischgut. Hierbei ist der Betrieb des Ventilationssystems nicht sinnvoll, wie auch im Umsetzbetrieb oder bei Transportfahrten des Straßenfertigers ohne Mischgut.Modern road pavers used on the market have a ventilation system with an on and off switchable, uncontrolled fan to collect vapors and aerosols during installation, for example of asphalt in road construction, and to dissipate so that paver operators more comfortable working conditions and the immediate environment on the construction site is relieved by the targeted removal of such irritants. Certain machine functions and operating modes of the paver and the screed are now basically matched to the respective mix. Rolled asphalt, for example in road construction, is usually installed far above 100 ° C. with a mix bound with bitumen with a defined installation temperature, whereby the heaters of the screed are also operated correspondingly powerfully. As a result, vapors and aerosols are released, for example, from the bitumen reinforced. On the other hand, hardly any steam and aerosol are released in the case of hydraulically bound mixed products, also because the heating devices are not or only moderately operated. The same applies to concrete mix. In this case, the operation of the ventilation system does not make sense, as in Umsetzbetrieb or when transporting the paver without mix.

Es obliegt somit der Aufmerksamkeit und dem Fachwissen des Bedienungspersonals, ob und wann das Ventilationssystem eingeschaltet oder nicht ausgeschaltet wird. Aufgrund dieses menschlichen Faktors ist eine effiziente und sinnvolle Verwendung des Ventilationssystems nicht in jedem Einbaufall gewährleistet. So kann das Ventilationssystem wegen beispielsweise der Geräuschbelästigung abgeschaltet bleiben, obwohl es eigentlich benötigt würde, oder nicht mehr abgeschaltet werden, obwohl es eigentlich nicht benötigt würde.It is therefore the attention and expertise of the operator to determine if and when the ventilation system is turned on or not turned off. Due to this human factor, an efficient and meaningful use of the ventilation system is not guaranteed in every installation case. For example, the ventilation system may be shut down because of, for example, noise nuisance, although it would actually be needed or not turned off, although it would not actually be needed.

Aus WO 2007/043966 A1 ist ein Ventilationssystem für einen asphaltverarbeitenden Straßenfertiger bekannt, das mindestens einen Katalysator und einen Lüfter aufweist und von einer elektronischen Steuerung geregelt wird, welche die Drehzahl des Lüfters und Hydraulikventile nach Maßgabe von Signalen regelt, die von Druck- und Temperatur-Messeinrichtungen im Bereich des Katalysators und wenigstens eines Reizstoffsensors bereitgestellt werden. Die automatische Regelung des Ventilationssystems setzt ein, wenn das Ventilationssystem von einem Bediener eingeschaltet wird, wobei davon ausgegangen wird, dass im Betrieb des Straßenfertigers vom verarbeiteten Asphalt stets Gase austreten. Die Drehzahl des Lüfters wird zum Mindern der Geräuschbelästigung möglichst gering gehalten und nach einer Katalysator-Aufheizphase im Hinblick auf einen Gas-Solldruck im Katalysator geregelt.Out WO 2007/043966 A1 a ventilation system for a asphalt paver is known, comprising at least one catalyst and a fan and is controlled by an electronic control, which controls the speed of the fan and hydraulic valves in accordance with signals from pressure and temperature measuring devices in the region of the catalyst and at least one irritant sensor. The automatic control of the ventilation system starts when the ventilation system is switched on by an operator, assuming that gases always escape from the processed asphalt during operation of the paver. The speed of the fan is used to reduce the noise nuisance kept as low as possible and regulated after a catalyst heating phase with respect to a target gas pressure in the catalyst.

In bekannten Straßenfertigern sind für das Ventilationssystem zwei unterschiedliche Betriebsarten üblich. Das Ventilationssystem wird entweder grundsätzlich eingeschaltet und ungeregelt eingeschaltet gehalten, solange die Primärantriebsquelle, d.h., der Dieselmotor, läuft, oder das Ventilationssystem wird durch einen Bediener fallweise eingeschaltet und abgeschaltet, der die Notwendigkeit des Betriebs der Ventilationseinrichtung nach eigenem Ermessen beurteilt. Da das Ventilationssystem nicht nur einen beträchtlichen Energiebedarf hat z. B. durchaus 10 kW, und der Betrieb des Ventilationssystems allerdings nur bei bestimmten Mischgutarten oder Mischguttemperaturen bzw. Betriebsarten des Straßenfertigers tatsächlich sinnvoll ist, bedeutet die erste Betriebsart eine schlechte Energiebilanz für den Straßenfertiger, und eine auch bei Umsetzbetrieb des Straßenfertigers oder in dessen Transportphase ohne Mischgut unzweckmäßige Lärmbelästigung. Bei der zweiten Betriebsart hängt der sinnvolle Einsatz des Ventilationssystems vom Urteil, der Aufmerksamkeit, und auch dem Wohlwollen des Bedieners ab, d.h. einem menschlichen Faktor, der eine effiziente und sinnvolle Verwendung des Ventilationssystems nicht stets gewährleistet. Die deutliche Geräuschbelästigung durch den Lüfter und einen Abblasstrang verleitet nämlich Bediener häufig dazu, das Ventilationssystem gar nicht in Betrieb zu nehmen, obwohl es grundsätzlich sinnvoll wäre. Auch tendieren Bediener oftmals aufgrund äußerer Einflüsse dazu, das Abschalten des Ventilationssystems zu vergessen oder zu unterlassen. Ferner kann es Grenzfälle geben, in denen Bediener nicht sicher sind, ob ein Betrieb des Ventilationssystems sinnvoll ist oder nicht, weil keine eindeutigen oder aussagekräftigen Informationen vorliegen. Das Ventilationssystem wird dann entweder nicht eingeschaltet, obwohl es sinnvoll wäre, oder eingeschaltet, obwohl es nicht sinnvoll ist.In known road pavers, two different operating modes are common for the ventilation system. The ventilation system is either kept switched on and uncontrolled switched on as long as the prime mover source, i.e., the diesel engine, is running, or the ventilation system is switched on and off on a case by case basis by an operator who judges the need to operate the ventilator at its discretion. Since the ventilation system not only has a considerable energy consumption z. B. quite 10 kW, and the operation of the ventilation system, however, only makes sense in certain Mischgutarten or Mischguttemperaturen or modes of the paver, the first mode means a poor energy balance for the paver, and even in Umsetzbetrieb the paver or in its transport phase without Mischgut inconvenient noise pollution. In the second mode of operation, the sensible use of the ventilation system depends on the judgment, attention, and also the goodwill of the operator, i. a human factor that does not always ensure an efficient and meaningful use of the ventilation system. Namely, the significant noise pollution by the fan and a Abblasstrang tempted operators often to not even take the ventilation system in operation, although it would be useful in principle. Also, operators often tend to forget or refrain from turning off the ventilation system due to external influences. Further, there may be borderline cases where operators are not sure whether operation of the ventilation system is useful or not because there is no clear or meaningful information. The ventilation system will then either not be turned on, although it would be useful or turned on, although it does not make sense.

Ein Straßenfertiger mit einem Ventilationssystem ist bekannt aus US 5 938 371 A . In diesem Straßenfertiger ist der Tunnel des Längsförderers im Deckenbereich mit einer Doppelwand ausgebildet, so dass hier zum Lüfter ein Ansaugkanal verläuft, von dem sich ein Abblasstrang nach oben über den Führerstand des Straßenfertigers erstreckt. An den Ansaugkanal sind Ansaughauben beispielsweise oberhalb des Mischgutbunkers, oberhalb der Querverteilschnecke und gegebenenfalls an oder hinter der Einbaubohle angeschlossen, die Dämpfe und Aerosole sammeln und ansaugen.A paver with a ventilation system is known US 5,938,371 A , In this paver, the tunnel of the longitudinal conveyor is formed in the ceiling area with a double wall, so that the fan here runs an intake, from which extends a Abblasstrang up over the cab of the paver. To the intake duct suction hoods are connected, for example, above the Mischgutbunkers, above the transverse auger and optionally on or behind the screed, collect the vapors and aerosols and suck.

Der Erfindung liegt die Aufgabe zugrunde, einen Straßenfertiger sowie ein Verfahren anzugeben, die hinsichtlich der Energieeffizienz oder Energiebilanz im Hinblick auf den Einsatz eines Ventilationssystems verbessert sind, und die eine Komfortsteigerung und Entlastung von Bedienern ermöglichen.The invention has for its object to provide a road paver and a method that are improved in terms of energy efficiency or energy balance in terms of the use of a ventilation system, and allow comfort and relief of operators.

Die gestellte Aufgabe wird mit den Merkmalen des Patentanspruches 1 und den Merkmalen des Verfahrensanspruches 6 gelöst.The stated object is achieved with the features of claim 1 and the features of the method claim 6.

Da das Ventilationssystem bzw. dessen Lüfter über die Maschinensteuerung oder eine eigene Ventilationssystem-Steuerung automatisch abhängig von einem ermittelten Bedarf zumindest ein- oder ausschaltbar ist, brauchen Bediener nicht einzugreifen, und wird das Ventilationssystem nur betrieben, wenn dies tatsächlich sinnvoll ist. Auf diese Weise wird die Energiebilanz des Straßenfertigers verbessert, wird das Ventilationssystem nur betrieben, wenn Dämpfe oder Aerosole und dgl. in nennenswertem Maß freigesetzt werden, und liegen für Bediener optimierte Arbeitsbedingungen und ein Schutz der direkten Umgebung vor. Dabei weist die Maschinensteuerung oder die Ventilationssystem-Steuerung eine Bedarfs-Entscheidungssektion auf, mit der, vorzugsweise, beschaffte, verfügbare oder vorhandene Informationen zu einer Mischgutart- und/oder Betriebsart- und/oder Maschinenfunktions-Vorwähl- oder Einstelleinrichtung und/oder einer Temperaturmesseinrichtung des Straßenfertigers und/oder zu einer Reizstoff-Konzentration verarbeitbar sind. Diese Informationen sind aussagefähig und zuverlässig, auch in Grenzfällen, in denen ein Bediener gegebenenfalls überfordert wäre, und führen zum Einschalten des Ventilationssystems nur dann, wenn der Betrieb aufgrund der verfügbaren Informationen tatsächlich sinnvoll ist. Zumindest in der Maschinensteuerung ist eine Eingabe- und/oder Anzeigesektion für Mischgutarten und/oder Mischguttemperaturen und/oder Einbautemperaturen und/oder Verdichtungseinstellungen und/oder Bohlenaufheiztemperaturen und/oder einen Zielwert einer Reizstoff-Konzentration in einem Absaugbereich vorgesehen, über die der Entscheidungssektion erforderliche Informationen lieferbar sind. In der Eingabe- und/oder Anzeigesektion können auch Betriebsarten, Maschinenfunktionen, die Heizleistung von Bohlenheizeinrichtungen oder dergleichen eingestellt oder angezeigt, und gleich in aussagefähige Informationen für die Entscheidungssektion umgesetzt werden.Since the ventilation system or its fan via the machine control or its own ventilation system control automatically depending on a determined need at least on or off, operators do not need to intervene, and the ventilation system is operated only if this is actually useful. In this way, the energy balance of the paver is improved, the ventilation system is operated only when vapors or aerosols and the like are released to a significant degree, and are available for operator optimized working conditions and protection of the immediate environment. In this case, the machine control or the ventilation system control has a demand-decision section, with the, preferably, acquired, available or existing information for a Mischgutart- and / or mode and / or Maschinenfunktions Vorwähl- or adjustment and / or a temperature measuring device of Road finisher and / or are processable to an irritant concentration. This information is meaningful and reliable, even in borderline cases in which an operator might be overwhelmed, and lead to switching on the ventilation system only if the operation actually makes sense based on the information available. At least in the machine control, an input and / or display section for mixed material types and / or mixed product temperatures and / or installation temperatures and / or compaction settings and / or screed heating temperatures and / or a target concentration of irritant concentration in a suction area is provided via the information required by the decision section are available. In the input and / or display section also operating modes, machine functions, the heating power of screed heating devices or the like can be set or displayed and immediately converted into meaningful information for the decision section.

Verfahrensgemäß wird zunächst ein vorab definierter Bedarf für den Betrieb des Ventilationssystems bzw. Lüfters ermittelt, und wird das Ventilationssystem bzw. der abgeschaltete Lüfter nur nach Ermittlung des definierten Bedarfes zumindest automatisch eingeschaltet und gegebenenfalls mindestens über die Zeitdauer des anliegenden Bedarfes betrieben. Der Bedarf wird abhängig von der Betriebsart oder Maschinenfunktion des Straßenfertigers und/oder der Mischgutart und/oder der Mischguttemperatur ermittelt. Wird der Bedarf nicht oder nicht mehr ermittelt, wird der Lüfter abgeschaltet. Der Bediener ist von der Entscheidung, das Ventilationssystem zu betreiben oder nicht zu betreiben, freigestellt, und kommt dennoch in den Genuss des Ventilationssystems, falls dessen Einsatz sinnvoll ist, während er durch die Arbeitsgeräusche des Ventilationssystems nicht belästigt oder beeinträchtigt ist, wenn mangels ermittelten Bedarfs ein Betrieb des Ventilationssystems tatsächlich nicht sinnvoll ist und dieses abgeschaltet bleibt.According to the method, first of all a predefined demand for the operation of the ventilation system or fan is determined, and the ventilation system or the switched-off fan is at least automatically switched on only after determination of the defined requirement and optionally operated at least over the duration of the applied demand. Of the Demand is determined depending on the operating mode or machine function of the paver and / or the Mischgutart and / or the mixed product temperature. If the demand is not or no longer determined, the fan is switched off. The operator is free from the decision to operate or not operate the ventilation system and still benefit from the ventilation system if it makes sense to use it, while not being bothered or affected by the working noise of the ventilation system, if lacking identified needs An operation of the ventilation system actually does not make sense and this remains switched off.

Bei einer zweckmäßigen Ausführungsform weist der Straßenfertiger wenigstens eine Messeinrichtung für den Istwert der Mischguttemperatur und/oder der Eihbautemperatur und/oder der Einbaubohlentemperatur und/oder der Reizstoff-Konzentration auf, vorzugsweise im Bereich eines Gutbunkers und/oder eines Längsförderers und/oder der Einbaubohle und/oder einem Absaugbereich, um zuverlässig die jeweilige Isttemperatur oder Ist-Konzentration erfassen und für die Entscheidung verwenden zu können, das Ventilationssystem einzuschalten oder abzuschalten.In an expedient embodiment, the paver has at least one measuring device for the actual value of the mixed product temperature and / or the egg temperature and / or the screed temperature and / or the irritant concentration, preferably in the area of a Gutbunkers and / or a longitudinal conveyor and / or the screed and / or a suction area to reliably detect the respective actual temperature or actual concentration and use for the decision to turn on or off the ventilation system.

Bei einer zweckmäßigen Ausführungsform ist zumindest die Maschinensteuerung online oder fallweise mit einem Informationen für die Entscheidung über den Bedarf oder Nicht-Bedarf liefernden Baustellen-Management-System verlinkt oder verlinkbar, das, z.B. in einem diese Informationen bereithaltenden Planungsbüro, definitive Informationen bereitstellt, die der Straßenfertiger bzw. dessen Maschinensteuerung zum automatischen Ein- oder Abschalten des Ventilationssystems im Hinblick auf optimale Energieeffizienz verwerten kann.In an expedient embodiment, at least the machine controller is linked or linked, on-line or occasionally, with a site management system providing decision-making information on demand or non-demand, which may be e.g. in a planning office that provides this information, provides definitive information that the paver or its machine control can use to automatically switch the ventilation system on or off in terms of optimum energy efficiency.

Bei einer zweckmäßigen Verfahrensvariante wird der Bedarf für den Betrieb des Ventilationssystems anhand wenigstens eines ausgewählten Parameters der für den Einbau bestimmten Mischgutart und/oder in Zuordnung zu einer für den Einbau wählbaren Maschinenfunktion und/oder Betriebsart und/oder einer im Straßenfertiger durchgeführten oder gewählten Zustandsbestimmung oder einer Messung definiert, vorzugsweise automatisiert in einer Entscheidungssektion der Maschinensteuerung oder einer Ventilationssystem-Steuerung.In a suitable process variant, the need for the operation of the ventilation system based on at least one selected parameter of Mischgutart intended for installation Mischgutart and / or in association with a selectable for installation machine function and / or operating mode and / or carried out in the paver state or state determination a measurement defined, preferably automated in a decision section of the machine control or a ventilation system control.

Ferner kann es zweckmäßig sein, als den Bedarf definierende Maschinenfunktion des Straßenfertigers den Betrieb und/oder mindestens eine vorbestimmte Leistungsstufe einer Einbaubohlen-Heizeinrichtung und/oder eine Mischgut-Versichtungseinstellungsvorwahl, beispielsweise für Verdichtungswerkzeuge der Einbaubohle, und/oder eine gemessene Reizstoff-Istkonzentration im Vergleich zu einem Zielwert zu verwenden.Furthermore, it may be expedient to use the machine function of the paver defining the requirement as the operation and / or at least a predetermined power level of a screed heater and / or a Mischgut-Versichtungseinstellungsvorstellungs, for example, for compaction tools of the screed, and / or a measured irritant concentration in comparison to use to a target value.

Die gemessene Reizstoff-Ist-Konzentration könnte gegebenenfalls zum automatischen Einschalten und/oder Abschalten des Ventilationssystems verwendet werden.The measured actual irritant concentration could optionally be used to automatically turn on and / or turn off the ventilation system.

Alternativ oder additiv kann als den Bedarf definierende Zustandsbestimmung oder Messung die Mischgut-Einbautemperatur oder Bohlen-Isttemperatur bzw. Bohlentemperaturvorwahl oberhalb eines vorbestimmten Temperaturwertes, vorzugsweise etwa 100°C oder mehr, verwendet werden.Alternatively or additionally, condition determination or measurement defining the requirement can be the mixing material installation temperature or plank actual temperature or screed temperature preselection above a predetermined temperature value, preferably about 100 ° C. or more.

Dabei kann die Maschinensteuerung oder die Ventilationssystem-Steuerung bzw. Entscheidungssektion so ausgelegt oder programmiert sein, dass der Lüfter zumindest im Umsetzbetrieb und/oder für Transportfahrten des Straßenfertigers, die z.B. ohne Mischgut ausgeführt werden, automatisch abgeschaltet wird und solange abgeschaltet gehalten bleibt, bis erneut ein Bedarf für den Betrieb des Ventilationssystems ermittelt wird.In this case, the machine control or the ventilation system control or decision section may be designed or programmed so that the fan, at least in the conversion operation and / or for transporting the paver, the e.g. run without mixing, is automatically switched off and kept switched off until again a need for the operation of the ventilation system is determined.

Zweckmäßig wird die Leistung des Ventilationssystem und/oder Drehzahl des eingeschalteten Lüfters geregelt, beispielsweise über einen Vergleich zwischen einem Zielwert und wenigstens einem gemessenen Istwert der Reizstoff-Konzentration z. B. in einem Absaugbereich des Straßenfertigers. Die Leistung wird automatisch oder bedienergeführt so geregelt, dass gerade so viele Reizstoffe abgesaugt werden wie nötig. Dadurch bleibt auch die Geräuschbelästigung in Situationen minimal, in denen gerade weniger Reizstoffe abgesondert werden.Suitably, the power of the ventilation system and / or speed of the switched-on fan is controlled, for example, by comparison between a target value and at least one measured actual value of the irritant concentration z. B. in a suction of the paver. The performance is automatically or user-controlled so regulated that just as many irritants are extracted as necessary. This also minimizes noise pollution in situations where fewer irritants are being secreted.

Zweckmäßig erfolgt die Regelung automatisch, z. B. auch unter Beiziehen weiterer aussagefähigen Informationen, und gegebenenfalls mit einer Nachlaufphase, selbst wenn kein Einbaugut mehr verarbeitet wird.Appropriately, the scheme is automatic, z. B. also taking into account other meaningful information, and optionally with a follow-up phase, even if no more built-in material is processed.

Dazu sollte die Leistung des Lüfters regelbar sein, z. B. die eines elektrischen oder hydraulischen Lüfter-Antriebsmotors, und sollte ein Regler mit der Steuervorrichtung verlinkt sein.For this purpose, the performance of the fan should be controllable, z. As an electric or hydraulic fan drive motor, and a controller should be linked to the controller.

Der Straßenfertiger F weist in einem Chassis 3 vorderseitig einen Gutbunker 4 auf, der mit Mischgut G, beispielsweise von einem Lastkraftwagen, von einem Förderband oder einem Beschickerfahrzeug 5 befüllbar ist, und von dem sich unterseitig ein Längsförderer 10 zu einem hinteren Ende des Chassis 3 erstreckt. Hinter dem Gutbunker 4 ist eine Primärantriebsquelle 6, beispielsweise ein Dieselmotor, angeordnet, hinter welchem auf dem Chassis 3 ein Führerstand 7 mit einer Maschinensteuerung 8 platziert ist. Die Maschinensteuerung 8 umfasst u.a. eine Entscheidungssektion 9 und, vorzugsweise eine Eingabe- und Anzeigesektion 27, und steht beispielsweise in Verbindung mit einem bordeigenen Ventilationssystem 12 des Straßenfertigers F, und weiteren nicht hervorgehobenen Funktionsbaugruppen des Straßenfertigers F und/oder der Einbaubohle 2. Das Ventilationssystem 12 umfasst wenigstens einen ein- und abschaltbaren Lüfter 13, nicht gezeigte Kanäle zu beispielsweise diversen Ansaugvorrichtungen 14, beispielsweise im Bereich des Gutbunkers 4, im Bereich des Längsförderers 10, am Heck des Chassis 3 und im Bereich der Einbaubohle 2, sowie einen Abblasstrang 15, der sich nach oben über das Dach des Führerstandes 7 erstreckt.An in Fig. 1 Road paver F shown schematically comprises a traction machine 1 driving at low installation working speed or faster transport traveling speed and at least one screed 2 towed by the tractor 1 for installing a cover layer 24 of a mix G during installation work of the paver F. The paver F has in a chassis 3 on the front side Gutbunker 4, which is filled with mix G, for example, by a truck, by a conveyor belt or a feeder vehicle 5, and from which a longitudinal conveyor 10 extends to a rear end of the chassis 3 at the bottom. Behind the Gutbunker 4 is a primary drive source 6, for example, a diesel engine, arranged behind which on the chassis 3, a cab 7 is placed with a machine control 8. The machine control 8 comprises inter alia a decision section 9 and, preferably an input and display section 27, and is for example in connection with an on-board ventilation system 12 of the paver F, and other non-highlighted function modules of the paver F and / or the screed 2. The ventilation system 12th comprises at least one on and off fan 13, not shown channels for example, various suction devices 14, for example in the field of Gutbunkers 4, in the region of the longitudinal conveyor 10, at the rear of the chassis 3 and in the screed 2, and a Abblasstrang 15, the extends upward over the roof of the cab 7.

Das Ventilationssystem 12 ist dazu vorgesehen, im Betrieb aus dem Mischgut G im Straßenfertiger F, vor und gegebenenfalls hinter der Einbaubohle 2 freigesetzte Dämpfe und Aerosole und dgl. zusammen mit Umgebungsluft aufzunehmen und über den Abblasstrang 15 nach oben, z.B. durch eine nicht gezeigte Filtervorrichtung von Bedienern auf und beim Straßenfertiger F und der Einbaubohle 2, wie auch aus der direkten Umgebung des Straßenfertigers F abzuführen, indem diese gesammelten Reizstoffe abgesaugt und nach oben (oder hinten) abgeführt werden.The ventilation system 12 is intended to receive in operation from the mix G in the paver F, before and optionally behind the screed 2 liberated vapors and aerosols and the like. Together with ambient air and via the Abblasstrang 15 upwards, e.g. by a filter device, not shown by operators on and at the paver F and the screed 2, as well as from the immediate vicinity of the paver F dissipate by these accumulated irritants are sucked off and up (or back) to be dissipated.

Am Heck des Chassis 3 ist eine Querverteilvorrichtung 11, z.B. eine Querschnecke, angeordnet, die das von dem Längsförderer 10 auf ein Planum P (Untergrund) abgeworfene Mischgut G vor der Einbaubohle 2 verteilt. Die Einbaubohle 2 (eine Standardbohle unveränderlicher Grundbreite, oder eine Ausziehbohle variabler Arbeitsbreite) ist mit Holmen 16 an seitlichen Anlenkstellen 17 am Chassis 3 angelenkt und weist jeweils ein Glättblech 23 und eine Tampervorrichtung 22 auf, für die in der Einbaubohle 2 beispielsweise elektrische Bohlen-Heizeinrichtungen 26 vorgesehen sind, die von einem von der Primärantriebsquelle 6 angetriebenen Drehstromgenerator mit elektrischer Leistung versorgt und über die Maschinensteuerung 8 auf bestimmte Heizleistungsstufen oder Heiztemperaturen eingestellt und geregelt werden. An der Einbaubohle 2 kann mindestens ein Außensteuerstand 25 angeordnet sein, an welchem ein Bediener Betriebsarten oder Maschinenfunktionen zumindest der Einbaubohle 2, gegebenenfalls aber auch des Straßenfertigers F einzustellen vermag, ähnlich wie an der Maschinensteuerung 8.At the rear of the chassis 3, a transverse spreading device 11, for example a transverse screw, is arranged, which distributes the mixed material G dropped by the longitudinal conveyor 10 onto a flat P (substrate) in front of the screed 2. The screed 2 (a standard screed invariable base width, or a Ausziehbohle variable working width) is articulated with spars 16 at lateral articulation points 17 on the chassis 3 and each has a screed plate 23 and a tamper device 22, for example, in the screed 2 electric Plank heaters 26 are provided which are powered by a driven by the primary drive source 6 three-phase generator with electrical power and set and controlled by the engine control unit 8 to certain Heizleistungsstufen or heating temperatures. On the screed 2, at least one outside control stand 25 can be arranged, on which an operator is able to set operating modes or machine functions of at least the screed 2, but optionally also the paver F, similar to the machine control 8.

Ferner kann zumindest eine Messeinrichtung 16, 17, 18 (ein Temperatursensor) vorgesehen sein, die z. B. Temperaturmesswerte an die Maschinensteuerung 8 liefert. In der gezeigten Ausführungsform ist z.B. wenigstens eine Temperaturmesseinrichtung 16 im Bereich der Einbaubohle 2 platziert, um die Einbautemperatur abzugreifen, und/oder eine Temperaturmesseinrichtung 17 im Bereich des Gutbunkers 4, um die Mischguttemperatur abzugreifen, oder auch (nicht gezeigt im Bereich des Längsförderers 10), und/oder in dem das Mischgut G liefernden Fahrzeug 5. Die Mischguttemperatur wird als Information 19 beispielsweise drahtlos oder kabelgebunden an die Maschinensteuerung 8 gemeldet. Alternativ oder additiv kann zumindest eine Messeinrichtung 16 für Ermittlungen der Ist-Konzentration der Reizstoffe z. B. in einem Absaugbereich 44, dienen (Fig. 6).Furthermore, at least one measuring device 16, 17, 18 (a temperature sensor) may be provided, the z. B. Temperaturmesswerte to the machine control 8 supplies. In the embodiment shown, for example, at least one temperature measuring device 16 is placed in the region of the screed 2 to tap the installation temperature, and / or a temperature measuring device 17 in the region of the Gutbunkers 4 to tap the mixed product temperature, or (not shown in the region of the longitudinal conveyor 10). , and / or in which the mixture G supplying vehicle 5. The mixed product temperature is reported as information 19, for example, wireless or wired to the machine control 8. Alternatively or additionally, at least one measuring device 16 for determining the actual concentration of irritants z. In a suction area 44, serve ( Fig. 6 ).

Ferner kann zumindest die Maschinensteuerung 8 online oder bei Bedarf mit einem Baustellen-Management-System 20 (Server oder Rechner) verlinkt oder verlinkbar sein, von dem Informationen 21 zur Mischgutart und/oder der Mischguttemperatur und/oder der Einbautemperatur und/oder bestimmten Betriebsarten und/oder bestimmten Maschinenfunktionen des Straßenfertigers oder der Einbaubohle und/oder bestimmte Verdichtungsvorwahleinstellungen bzw. Zielwerte für die Reizstoff-Konzentration bereitstellbar sind, und beispielsweise in der Entscheidungssektion 9 verarbeitet werden, um festzulegen, ob für den begonnenen oder zukünftigen Einbau das Ventilationssystem 12 bzw. dessen Lüfter 13 eingeschaltet werden soll, weil dies sinnvoll ist, oder nicht eingeschaltet oder ausgeschaltet werden soll. Auch Informationen, die an der Eingabe- und Anzeigesektion 27 der Maschinensteuerung 8 eingegeben werden, beispielsweise von einem Bediener, können in der Entscheidungssektion 9 verarbeitet werden, um die Entscheidung zu fällen, das Ventilationssystem 12 automatisch ein- oder abzuschalten.Furthermore, at least the machine control unit 8 can be linked or linked to a construction site management system 20 (server or computer) on-line or on demand, from the information 21 on Mischgutart and / or the mixed product temperature and / or the installation temperature and / or certain modes and or certain machine functions of the paver or the screed and / or certain compression setpoints or target values for the irritant concentration can be provided, and processed, for example, in the decision section 9 to determine whether the ventilation system 12 or its Fan 13 should be turned on, because this makes sense, or should not be turned on or off. Also, information input to the input and display section 27 of the engine controller 8, for example from an operator, may be processed in the decision section 9 to make the decision to automatically turn the ventilation system 12 on or off.

Alternativ könnte das Ventilationssystem 12 eine eigene Ventilationssystem-Steuerung 8' aufweisen, die das Ventilationssystem 12 bzw. dessen Lüfter 13 automatisch und bedienerunabhängig stets dann einschaltet, oder abschaltet, wenn dies aufgrund eines ermittelten Bedarfs oder nicht gegebenen Bedarfs sinnvoll ist. Zweckmäßig ist die Leistung bzw. Drehzahl des Lüfters 13 regelbar.Alternatively, the ventilation system 12 could have its own ventilation system control 8 ', the ventilation system 12 and its fan 13 automatically and operator-independent always turns on, or turns off, if this makes sense on the basis of an identified need or need. Suitably, the power or speed of the fan 13 is adjustable.

Ob der Betrieb des Ventilationssystems 12 sinnvoll ist oder geregelt werden soll, oder nicht, richtet sich nach bestimmten Betriebszuständen oder Maschinenfunktionen des Straßenfertigers oder der Einbaubohle, und/oder nach bestimmten Mischgutarten und/oder bestimmten Mischguttemperaturen wie auch einer gegebenenfalls gemessenen Reizstoff-Konzentration, als entscheidenden Parametern zum Feststellen des Bedarfs für den Betrieb und gegebenenfalls eine Regelung des Ventilationssystems. Die Maschinensteuerung 8 (oder die Ventilationssystem-Steuerung 8') schaltet nach der getroffenen Entscheidung und Ermittlung des Bedarfs das Ventilationssystem 12 bzw. den Lüfter 13 automatisch ein und hält es z.B. eingeschaltet und regelt gegebenenfalls, solange Bedarf anliegt. Hingegen wird das Ventilationssystem 12 und dessen Lüfter 13, abgeschaltet oder abgeschaltet gehalten, solange kein Bedarf oder falls kein Bedarf mehr ermittelt wird.Whether or not the operation of the ventilation system 12 is useful or to be controlled depends on certain operating conditions or machine functions of the paver or screed, and / or on certain types of mix and / or specific mix temperatures as well as an optionally measured irritant concentration decisive parameters for determining the need for operation and, where appropriate, regulation of the ventilation system. The engine controller 8 (or the ventilation system controller 8 ') automatically turns on and holds the ventilation system 12 and the fan 13, respectively, after making the decision and determining the demand. switched on and regulates if necessary, as long as need arises. On the other hand, the ventilation system 12 and its fan 13 are kept switched off or switched off as long as there is no need or if no more need is detected.

Voreinstellungen der von den Verdichtungswerkzeugen der Einbaubohle 2 in der Deckenschicht 24 erzeugten Verdichtung können an der Maschinensteuerung vorgewählt werden, und lassen sich ebenfalls als ein aussagefähiger Parameter für die Entscheidung nutzen. Mischgutarten, die mit Bitumen gebunden sind und mit definierten Einbautemperaturen oder Mischguttemperaturen von beispielsweise mehr als 100°C eingebaut werden müssen, repräsentieren ebenfalls einen Bedarf definierende Parameter. Hydraulisch gebundene Mischgutarten oder Betonmischgüter benötigen hingegen meist den Betrieb des Ventilationssystems 12 nicht, wie auch eine Betriebsart des Straßenfertigers mit niedrigen Mischguttemperaturen unterhalb etwa 100°C oder Mischgutarten ohne Bitumenbindung, die mit Umgebungstemperatur eingebaut werden. Da dann auch die Heizeinrichtungen der Einbaubohle 2 nicht oder nur moderat betrieben werden, lässt sich auch dies als ein Parameter zur Entscheidungsfindung nutzen. Ferner ist beim Umsetzen des Straßenfertigers (Umsetzbetrieb) oder während einer Transportphase ohne Mischgut der Betrieb des Ventilationssystems 12 nicht sinnvoll, so dass auch diese Betriebsarten als Parameter für die Entscheidung, das Ventilationssystem 12 einzuschalten oder abzuschalten, verarbeitbar sind. Auch kann hierfür die gemessene Reizstoff-Ist-Konzentration alternativ oder additiv herangezogen werden.Presets of the compaction generated by the compaction tools of the screed 2 in the ceiling layer 24 can be preselected on the machine control and can also be used as a meaningful parameter for the decision. Mixed material types which are bound with bitumen and have to be installed with defined installation temperatures or mixed product temperatures of, for example, more than 100 ° C., also represent parameters defining need. Hydraulically bound Mischgutarten or concrete mixes, however, usually do not require the operation of the ventilation system 12, as well as an operating mode of the paver with low Mischguttemperaturen below about 100 ° C or Mischgutarten without Bitumenbindung, which are installed with ambient temperature. Since then also the heaters of the screed 2 are not or only moderately operated, this can also be used as a parameter for decision-making. Furthermore, the operation of the ventilation system 12 is not useful when converting the paver (Umsetzbetrieb) or during a transport phase without mix, so that these modes as parameters for the decision to turn on or off the ventilation system 12, are processable. Also, the measured irritant-actual concentration can be used alternatively or in addition.

In dem Flussdiagramm in Fig. 2 wird im Block 28 verfahrensgemäß eine Auswahl unter verfügbaren Parametern zur Mischgutart getroffen, beispielsweise in der Entscheidungssektion 9, und wird nach getätigter Auswahl in dem Block 29 abgefragt, ob der Betrieb des Ventilationssystems der Mischgutart zugeordnet werden kann. Ist die Antwort dieser Abfrage "Ja", dann wird im Block 30 das Ventilationssystem in Betrieb genommen und so lange betrieben, bis als Antwort "Nein" anliegt. Ist die Antwort hingegen von vornherein "Nein", dann bleibt im Block 31 das Ventilationssystem 12 außer Betrieb.In the flowchart in Fig. 2 In accordance with the method, in block 28, a selection is made among available parameters for the mixed material type, for example in the decision section 9, and after selection has been made in block 29, a query is made as to whether the operation of the ventilation system can be assigned to the mixed material type. If the answer to this query is "yes", then in block 30 the ventilation system is put into operation and operated until the answer "no" is present. If, on the other hand, the answer is "no" from the outset, then in block 31 the ventilation system 12 remains out of operation.

In der Verfahrensvariante in Fig. 3 wird im Block 32 die Messung der Temperatur des Mischgutes oder die Information über die Mischguttemperatur verarbeitet, und wird im Block 33 abgefragt, ob der Betrieb des Ventilationssystems der Mischguttemperatur zugeordnet ist. Ist die Antwort "Ja", dann wird im Block 30 das Ventilationssystem in Betrieb genommen und in Betrieb gehalten. Ist die Antwort "Nein", dann wird im Block 31 das Ventilationssystem nicht in Betrieb genommen bzw. abgeschaltet.In the process variant in Fig. 3 In block 32, the measurement of the temperature of the mixed material or the information about the mixed product temperature is processed, and in block 33 it is queried whether the operation of the ventilation system is assigned to the mixed product temperature. If the answer is "yes", then in block 30, the ventilation system is put into operation and kept in operation. If the answer is "No", then in block 31, the ventilation system is not put into operation or switched off.

In der Verfahrensvariante in Fig. 4 wird im Block 34 eine Auswahl einer bestimmten Maschinenfunktion getroffen, und wird im Block 35 abgefragt, ob der Betrieb des Ventilationssystems der Maschinenfunktion zugeordnet ist. Ist die Antwort "Ja", wird im Block 30 das Ventilationssystem in Betrieb genommen. Ist die Antwort "Nein" im Block 35, dann wird im Block 31 das Ventilationssystem nicht in Betrieb genommen oder abgeschaltet.In the process variant in Fig. 4 If a selection of a specific machine function is made in block 34, a query is made in block 35 as to whether the operation of the ventilation system is assigned to the machine function. If the answer is "yes", in block 30 the ventilation system is put into operation. If the answer is "No" in block 35, then in block 31 the ventilation system is not put into operation or switched off.

In der Ausführungsform in Fig. 5 wird im Block 36 eine Auswahl der Betriebsart des Straßenfertigers bzw. der Einbaubohle getroffen, und diese Auswahl an den Block 37 übermittelt. Im Block 37 wird abgefragt, ob der Betrieb des Ventilationssystems der ausgewählten Betriebsart zugeordnet ist. Ist die Antwort "Ja", wird im Block 30 das Ventilationssystem in Betrieb genommen und in Betrieb gehalten. Ist die Antwort "Nein", dann wird im Block 31 das Ventilationssystem nicht in Betrieb genommen bzw. abgeschaltet.In the embodiment in FIG Fig. 5 In block 36, a selection of the operating mode of the road paver or screed is made, and this selection is transmitted to block 37. In block 37 it is queried whether the operation of the ventilation system is assigned to the selected operating mode. If the answer is "yes", in block 30 the ventilation system is put into operation and kept in operation. If the answer is "No", then in block 31, the ventilation system is not put into operation or switched off.

Obwohl ein Bediener an der Maschinensteuerung 8 (bzw. der Ventilationssystem-Steuerung 8') Eingaben tätigen oder Betriebszustände abfragen kann, wird die Entscheidung, das Ventilationssystem 12 einzuschalten und/oder zu regeln oder abzuschalten bzw. eingeschaltet zu halten oder abgeschaltet zu halten, zweckmäßig bedienerunabhängig und automatisch über die Entscheidungssektion 9 getroffen, d.h. es wird zunächst der Bedarf festgestellt, dass das Ventilationssystem in Betrieb sein soll. Wird kein Bedarf festgestellt oder kein Bedarf mehr ermittelt, dann wird das Ventilationssystem 12 automatisch gar nicht in Betrieb genommen, oder abgeschaltet. Gegebenenfalls wird das Ventilationssystem automatisch auch in einer Nachlaufphase betrieben.Although an operator at the machine control 8 (or the ventilation system controller 8 ') may enter inputs or interrogate operating conditions, the decision to turn on and / or regulate the ventilation system 12 or keep it on or off is appropriate operator-independent and automatically made via the decision section 9, ie it is first determined the need that the ventilation system should be in operation. If no need is determined or no need is determined, then the ventilation system 12 will become automatic not put into operation, or switched off. Optionally, the ventilation system is automatically operated in a follow-up phase.

Fig. 6 zeigt als Detailvariante einen drehzahl- und/oder leistungsregelbaren Lüfter 13, dessen Antrieb 42 (z. B. Elektro- oder Hydromotor) von einem Regler 40 gesteuert wird, der einen von der Messeinrichtung 16, z. B. in einen Absaugbereich 44, gemessenen Reizstoff-Konzentrations-Istwert 38 mit einem in einer Eingabesektion 45 bereitgehaltenen oder eingegebenen Zielwert 39 vergleicht und die Leistung 43 anpasst. Fig. 6 shows a detailed variant of a speed and / or power adjustable fan 13, the drive 42 (eg., Electric or hydraulic motor) is controlled by a controller 40, one of the measuring device 16, z. B. in a suction 44, measured irritant concentration actual value 38 with a prepared in an input section 45 or entered target value 39 and adjusts the performance 43.

Die Drehzahl des Lüfters 13 ist dann nur so hoch wie gerade nötig. Der Istwert 38 könnte allein oder in Verbindung mit den erwähnten anderen Informationen zur Entscheidung verwendet werden oder Ventilationssystem 12 ein- oder abzuschalten und/oder bedarfsgerecht zu regeln. Damit ist eine wünschenswerte Energieeinsparung verbunden, wird das Betriebsgeräusch des Ventilationssystems 12 oftmals verringert, und wird vor allem eine unzweckmäßig starke Abkühlung des Einbauguts bei verminderter Lüfterdrehzahl und verringertem Luftdurchsatz vermieden, beispielsweise bei einer Unterbrechung des Einbauprozesses.The speed of the fan 13 is then only as high as just needed. The actual value 38 could be used alone or in conjunction with the other information mentioned for the decision or to switch ventilation system 12 on or off and / or to regulate it as needed. This is associated with a desirable energy saving, the operating noise of the ventilation system 12 is often reduced, and above all an inordinately heavy cooling of the paving material at reduced fan speed and reduced air flow is avoided, for example, in an interruption of the installation process.
