Problems solved by technology

Because the ventilation system not only has a considerable energy demand, for example around 10kW, but the operation of the ventilation system is actually only effective for a specific type of material mixture or material mixture temperature or operating mode of the road finishing machine, the first operating mode means Poor energy balance of road finishing machines and unsuitable noise pollution during site change operations of road finishing machines or during transport phases without loading material mixtures
In the second mode of operation, the proper use of the ventilation system also depends on the judgment, attention and good faith of the operator, i.e. it is a human factor, and such human factors cannot always ensure the effective and reasonable use of the ventilation system
Differential noise pollution from fans and exhaust ducts often causes operators not to run the ventilation system even though it is basically functioning
Also, due to external influences, operators often tend to forget or neglect to turn off the ventilation system
In addition, ambiguity can occur when operators cannot determine whether ventilation system operation is functioning due to unavailability of clear or meaningful information
Thus, the ventilation system may not be turned on when it would be functional, or it may be turned on when it is not

Embodiment Construction

[0025] exist figure 1 The road finishing machine F shown schematically in FIG. 2 comprises a self-propelled tractor 1 operating at a low drive speed during laying and at a faster drive speed during transport and site change drives. At least one screed 2 is towed by the tractor 1 for laying a road surface 24 of material mixture G during the laying drive of the road finishing machine F. The road finisher F has a hopper 4 at the front of the chassis 3 which can be filled with a material mixture G eg from a dump truck, a conveyor belt or a charging truck 5 . A longitudinal conveyor 10 extends to the rear end of the chassis 3 at the bottom side. Behind the hopper 4, a main drive source 6 (such as a diesel engine) is arranged, and behind the main drive source, a driver's platform 7 equipped with a machine console 8 on the chassis 3 is arranged. The machine console 8 comprises, inter alia, a decision section 9, and preferably an input and display section 27, and is connected, for e...

Abstract

In a road finishing machine (F) comprising at least one screed (2), a machine control (8), and a ventilation system (12) including a fan (13), the fan (13) can be switched on or off via the machine control (8) automatically independent of the operator and exclusively depending on demand. According to the invention, before or during the laying operation, a defined demand for the operation of the ventilation system (12) is determined, and during or for the laying operation, the ventilation system (12) is operated independent of the operator and automatically, and optionally power-controlled, upon determination of the defined demand.

Description

technical field [0001] The invention relates to a road finishing machine according to the preamble of claim 1 and also to a method according to the preamble of claim 9 . Background technique [0002] Modern road finishers on the market have ventilation systems with uncontrolled fans that can be switched on and off during paving operations to collect and release vapors or aerosols (e.g. from asphalt to be rolled during road construction steam or aerosols) so that the operator of the finisher and its screed can have more comfortable working conditions and the immediate surroundings on the construction site are less affected by the deliberate discharge of such irritants . Certain machine functions and operating modes of road finishers and screeds depend on the respective material mixture. In road construction, for example, asphalt to be rolled after laying is laid as an asphalt-bound mixture with a defined laying temperature, usually well above 100° C., forcing the heating of...
