Road finisher, shuttle buggy and a process for the preparation of a road surface as well as a method for operating a mobile feeder

摘要

Road finisher (10) are used for the production of road surfaces of road-building material such as, for example, asphalt. For the production of the road surface of the road building material used is, by means of a truck (48) is delivered and a supply container (14) of the road finisher (10) is supplied to. By means of steering instructions of a person, the truck (48) to the front end (21) of the road finisher (10) maneuvered. This procedure for the filling of the storage container (14) is very costly, since the process of the filling by at least one person constantly has to be controlled. Thus the incorporation of road-building material uniformly and can be carried out continuously, a paving screed (17) must always be supplied with sufficient road-building material. Due to the complexity and the size of the road finisher (10), in particular the width of the paving screed (17) is a detecting the road-building material in front of the paving screed (17) by a sensor, is insufficiently. The material flow from the reservoir (14) to the paving screed (17) can thus be controlled only very inaccurate. The present invention provides a device and a method in which the production of the road surface is at least partially, by an automated. For this purpose, the truck (48) for supplying road-building material into the storage container (14) of at least one sensor (22) of the road finisher is detected. Furthermore, the road finisher (10) associated with a plurality of sensors for the determination of the material flow.
