Definitions

  • the present invention relates to an automatic device for controlling the operation of the brushes in wheeled vehicles for cleaning floors.
  • These vehicles are generally motorised and move on wheels, steered by an operator seated on the vehicle itself.
  • the rotation speed of the brushes in these vehicles is fixed, although vehicles are known where it is possible to regulate the speed of the brushes manually. In other words, while the driver is steering the vehicle, he adjusts the rotation speed of the brushes according to the speed at which they are advancing.
  • Another problem of the known technology is due to the fact that the side brushes cannot be used while the central brush is in its raised position.
  • An object of the present invention is therefore to solve the above mentioned problems by providing a vehicle of this type which is able to automatically adjust the operation of the brushes as a function of the condition of the vehicle, that is according to its state parameters (advance speed of same and/or state of at least one of the brushes). In this way, the driver need only adopt the appropriate speed for the ground conditions and can drive the vehicle safely.
  • the device detects the advance speed of the vehicle and consequently controls the brush rotation speed.
  • the device detects the operative or non-operative state of the central brush of the vehicle and consequently activates or deactivates the operation of the side brushes.
  • fig. 1, 1 indicates an automatic control device according to the present invention.
  • the detecting elements for detecting the speed of a wheel 3 which is rotatably mounted on a chassis 5 (shown in part) of a vehicle.
  • the detecting elements consist of an encoder which, as it is well known, basically consists of a fixed detector 7 to read off the revolutions of the wheel attached to the chassis and a rotating reference 9 integral to the wheel.
  • the number of revolutions of the wheel detected by the encoder is sent via a line 10 to automatic regulation elements 11.
  • These elements may be electronic means, a microprocessor for example.
  • Said automatic regulation elements 11 are connected via another line 12 to an electric motor 13 which enables the rotation of the brush 15.
  • the elements 11 allow to vary the rotation speed of the motor 13 as a function of the rotation speed of the wheel according to preset parameters laid down by the manufacturer or operator of the vehicle.
  • the motor is in turn coupled to one or more brushes 15.
  • the automatic regulation devices can be connected to a number of electric motors activating as many brushes.
  • the automatic regulation devices will not be connected to an electric motor but rather to a switchboard or integrated circuit for controlling the fluid. In this case, the automatic regulation devices will vary the brush rotation speed by controlling the flow of a fluid.
  • Line 4 as shown in fig. 1, makes it possible to detect the state of the brush 15 in order to consequently control, by means of elements 11, the operation of the remaining brushes of the vehicle.
  • the elements 11 can be used to activate or deactivate the side brushes 17 in accordance with the operative or non-operative state of the central brush 19.
  • the side brushes operate only if the central brush is in operation, that is if it is lowered in the direction of the bidirectional arrow A. In fact, only when the brush 19 is lowered all the blocking means on the controls 8 of the side brushes are freed and all the side brushes may be lowered, raised and activated either all together or only some at a time independently of one another. However, if the central brush has not been lowered, then it will not be possible to lower and activate the side brushes. In the same way, if the central brush is raised, the elements 11 will automatically operate the elements 8 to raise the side brushes 17 and disactivate them.
  • the device operates as follows. First of all, the operator starts the vehicle, and drives it over surfaces to be cleaned. The operator moves the vehicle at the advance speed which is most conducive to optimum cleaning.
  • the detector 7 reads the reference position 9 and is able to calculate the advance speed of the vehicle. It communicates this information via line 10 to the automatic electronic regulation elements 11. These elements, on this basis of their information, use the programme to process a particular control which is sent to the electric motor 13 via line 12. This control enables the motor and therefore the brush 15 to revolve at a speed with is a function of the advance speed of the vehicle.
  • the vehicle may now be driven by the operator with the brushes rotating at the most appropriate speed for the type of surface and dirt encountered during the passage of the vehicle. For example, if certain parts of the surface are particularly dirty, he will drive the vehicle slowly and the brush or brushes will also turn slowly in order to render their cleaning action more efficient. Thus an efficient cleaning is obtained.
  • the operator can also drive the vehicle safely and continuously since he is not obliged to change the brush speed manually.
  • the vehicle has a safety function which prevents an undesired activation of the side brushes independently of the activation of the central brush.
