Definitions

  • the invention relates to a method for setting a preselected sweeping mirror width of a roller broom rotatable about an axis according to the preamble of patent claim 1.
  • vehicles with rotating roller brushes are used to clean surfaces such as roads or tarmacs at airfields.
  • Important for an optimal cleaning result is among other things the correct sweeping mirror or the correct sweeping mirror width, i.e. the contact area between the rotating roller brush and the surface to be cleaned.
  • sensor pins of a sensor are fastened to a swivel arm, the sensor pins coming into contact with the outer surface of the roller broom during operation. They continuously generate pulses that are fed into the actuating device. If the roller brush becomes smaller in diameter due to wear, the impulses are interrupted. Both the roller brush and the swivel arm of the sensor have to be readjusted, whereupon pulses are again recorded in a further phase until a new readjustment is necessary due to the wear.
  • the known device is inaccurate because the diameter of the roller broom is not exactly determined, but only a certain diameter range is monitored in accordance with an allowable degree of wear.
  • the invention has for its object to provide a method for setting a preselected sweeping mirror width, which enables a much more precise determination of the roller diameter of the roller brush and a much more precise setting of a desired sweeping mirror width in order to achieve an optimal cleaning result with little wear.
  • the invention is not limited to determining only the roller diameter of the roller broom. Rather, the actual distance between the axis and the surface to be cleaned is also measured in a new way.
  • This measured variable is compared with the target distance, which results from the recorded roll diameter. If the two values differ, the target distance is then readjusted.
  • the additional determination of the actual distance between the axis and the surface to be cleaned can therefore advantageously be used to implement a control circuit in order to set a distance which corresponds to a desired constant sweeping level.
  • the actual distance between the axis and the surface to be cleaned is measured continuously, with the measured values supplied by the measuring device being averaged over time in order to derive the actual distance therefrom.
  • the height of the static rest position of the axis above the surface to be cleaned can also be determined, taking into account unevenness in the surface to be cleaned, and with the aid of the additionally measured roller diameter, it is possible to regulate the distance between the axis and the given cleaning surface.
  • the roller brush can be held above the surface with a control circuit so that a pre-selected sweeping mirror width is always guaranteed.
  • a further development of the invention provides that an ultrasonic sensor is used as the measuring device, which is arranged in a stationary manner on the support and guide frame of the roller broom.
  • the actual distance between the axis of the roller broom and the surface to be cleaned can be determined in a known manner in a simple manner, since ultrasound sensors are known per se, which is advantageous in economic terms. Otherwise there is also the possibility of the ultrasonic sensor subsequently to be arranged on a support and guide device of the roller broom.
  • the actual distance is preferably determined at different measuring locations on the axis. This measure helps to ensure cylindrical wear of the roller brush.
  • the invention further relates to a device according to the preamble of claim 6.
  • the invention has for its object to enable an accurate determination of the diameter of the roller broom and to create the conditions to perform an accurate adjustment of the desired sweeping mirror, the Sweeping level should remain as constant as possible. This is to create the prerequisite for an optimal cleaning result.
  • the measuring device offers the possibility of determining the actual actual distance between the axis of the roller broom and the surface to be cleaned, and with the aid of the control arrangement which is also provided for comparing the desired distance with the actual distance and for generating a setting variable derived therefrom the optimal distance of the axis can be determined.
  • the device for cleaning surfaces shown in FIG. 1 is generally arranged on a special vehicle and connected to it by a support and guide frame 40.
  • the guide frame 40 supports a roller broom 14 which can be rotated about an axis 12, the axis 12 of which is supported on the surface 10 to be cleaned by means of a support and guide device 38 and can be adjusted at a distance h by means of an adjusting device 16.
  • the adjustability of the distance h also makes it possible to set the contact surface between the roller brush 14 and the surface 10, this surface being referred to as a sweeping mirror b s p.
  • the roller brush 14 is driven by a drive device 36 in the direction of rotation d and during the cleaning process the device is simultaneously moved in direction f over the surface to be cleaned.
  • the distance h variable by means of the adjusting device 16 and the associated size of the sweeping mirror b s p are of crucial importance for the cleaning result.
  • the adjusting device 16 receives control signals from a measuring and control device 24, which determines the current roller diameter 2r via a sensor device 18.
  • the sensor device 18 comprises a probe body 22 arranged on a rod 34, which can be moved towards or away from the roller brush 14 via a feed device 26.
  • a displacement measuring device 28 and an acceleration sensor 30 are provided.
  • the probe body 22 is first moved in the direction of the roller broom by means of the feed device 26. It is expedient to arrange the feed device 26 such that the direction of travel is perpendicular to the axis 12. In its initial position, the probe body 22 is at a distance e from the axis 12.
  • the surface of the feeler body 22 comes into contact with the lateral surface 20 of the roller broom, it is set in motion by the bristles of the roller broom 14 running along the surface 32. These vibrations can be measured via an accelerometer 30 e.g. be recorded as structure-borne noise. The occurrence of the signal change recorded by the acceleration sensor 30 can then cause the measuring and control device 24 to stop the feed device 26.
  • the travel distance z can then be recorded and the roller diameter then results from the difference between the original distance e and the travel distance z. After detection of the travel path, the probe body 22 can then be moved back to its starting position in the opposite direction.
  • the distance h required for a predetermined sweeping mirror b s p can be determined, specifically using the formula As the drawing shows, it is the man Tel surface 20 of the roller broom 14 facing surface 32 of the probe body 22 is convex. This has the advantage that the bristles of the roller brush 14 gradually run up and down on the surface 32, so that excessive wear of the probe body 22 and also of the roller brush 14 at the point of contact is avoided.
  • measuring locations e.g. measured at the measuring points a and b.
  • Several, e.g. two sensor devices 18 can be provided, or a single sensor device 18 can also be used, which is then axially connected to the different measuring locations, e.g. a and b.
  • the roller brush 14 can then be aligned differently from the surface 10, so that the difference in wear is compensated for again and a uniform sweeping level b s p is achieved. In this way, the cleaning effect can be kept optimal over the entire width of the broom until the roller brush 14 is completely worn.
  • the probe body 22 is preferably only brought to the lateral surface 20 of the roller broom 14 at predetermined time intervals, and then withdrawn again.
  • the drive device 36 for the roller brush 14 is also connected to the control device 24.
  • the roller brush 14 is controlled in such a way that the rotational speed is changed as a function of the roller diameter 2r in order to achieve a constant peripheral speed.
  • the sensor device 18 already described and the control device 24 can also be used.
  • Fig. 2 shows a side view of the roller brush 14 in the sweeping mode.
  • a contact surface between the roller brush 14 and the surface to be cleaned which is shown here as a sweeping mirror b s p.
  • the distance h and half the roll diameter r are also shown.
  • the relationship between the distance h, the roller diameter 2r and the sweeping mirror b s p can be derived from these variables in accordance with the formula mentioned above.
  • the distance h required for a predetermined sweeping mirror b s p can be determined and set on the basis of the determined roller diameter 2r.
  • the actual distance h, st that actually exists after the setting which is decisive for the actual sweeping mirror width b s p.
  • the distance h of the axis 12 above the is continuously during the sweeping operation Surface 10 determined.
  • an ultrasonic sensor 42 is arranged on the support and guide frame 40, which continuously determines the actual distance h, st .
  • the height of the static rest position of the axis 12 above the surface 10 is determined by a temporal averaging of the distance to the surface 10 provided by the ultrasonic sensor 42.
  • the setpoint value for the height h son of the axis 12 can now be determined for the control of the height h of the axis 12 above the surface 10 in accordance with the formula given above.
  • the control arrangement 44 comprises a controller 46, which is followed by the adjusting device 16.
  • a measuring transducer 48 connects to the adjusting device 16, as a result of which the control loop is closed.
