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 rather only a certain diameter range is monitored in accordance with a permissible 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 travel path is measured, which is covered between an initial position of the probe body and a position in which the probe body comes into contact with the lateral surface of the roller broom.
  • the contact with the rotating roller broom causes the bristles of the roller broom to slide along the feeler body, thereby causing it to vibrate by means of an accelerometer can be clearly recorded.
  • roller diameter is determined at least at two different measuring locations on the lateral surface of the roller broom.
  • Different wear can be recognized and e.g. can be compensated for by changing the distance between the axis and the surface to be cleaned.
  • the sweeping level and consequently the cleaning result can be kept constant over the entire length of the roller brush.
  • the probe body is applied to the lateral surface only at predetermined time intervals.
  • the costs for the production of the corresponding device and the maintenance costs can be kept low and a high level of functional reliability achieved by using conventional components.
  • a further development of the invention provides that the rotational speed of the roller broom is controlled as a function of the roller diameter in order to achieve a constant peripheral speed.
  • This measure contributes to a further improvement in the cleaning effect, and the existing devices for determining the roller diameter can also be used for controlling the speed.
  • the invention further relates to a device according to the preamble of claim 5.
  • 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 should create the prerequisite for an optimal cleaning result.
  • the probe body can be moved by the feed device from an initial position in the direction of the roller broom, whereby the contact point of the probe body with the lateral surface of the roller broom can be determined.
  • This contact point can be identified in that the bristles of the roller brush slide over the probe body during operation and thereby excite it to vibrate.
  • the vibrations can be detected and evaluated using an accelerometer.
  • the path between the starting position of the probe body and the position in which contact with the lateral surface of the roller broom can be exactly determined via the path measuring device.
  • the device also makes it possible to repeat the determination of the roller broom diameter more frequently in order to be able to check the correctness of the measurement itself and to register progressive wear on the roller broom and to bring about a corresponding change in the adjusting device.
  • the probe body is formed with a convex surface facing the lateral surface of the roller broom, the probe body being arranged on a longitudinally displaceable rod of the feed device.
  • This configuration of the surface ensures that when the probe body touches the outer surface of the roller broom, the bristles gradually slide up and down, thereby protecting both the roller brush and the probe body from excessive wear and also having a clear point of contact on the probe body the bristles is created, which is advantageous for the accuracy of the measurement.
  • the feeler body Due to the longitudinally movable rod, the feeler body can be moved exactly in the direction of the axis, regardless of the respective roller diameter, so that the additional travel path that must be covered by the feed device represents exactly a measure of the decrease in the diameter of the roller broom. A complicated conversion of the measurement data can therefore be omitted.
  • two sensor devices are arranged at different measuring locations on the lateral surface of the roller broom.
  • a further embodiment of the invention provides that a sensor device is provided which can be moved axially parallel to the roller broom to different measuring locations.
  • This configuration makes it possible to detect uneven wear on the roller broom and, for example, to compensate for it by means of different changes in the distance between the axis and the surface to be cleaned so that a uniform sweeping level is achieved.
  • the described configuration can also be used advantageously when the roller broom is checked for wear and for device malfunctions.
  • the probe body rests on the lateral surface only at predetermined time intervals.
  • the accelerometer is designed as a structure-borne sound receiver.
  • the device can be constructed inexpensively.
  • a drive device is advantageous of the invention provided for the roller broom, which is connected to the measuring and control device and controlled in such a way that the speed can be controlled as a function of the roller diameter in order to achieve a constant peripheral speed.
  • both the method and the device measure the center distance during the sweeping operation.
  • the device for cleaning surfaces shown in Fig. 1 is usually 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 allows the contact area between the roller brush 14 and the surface 10 ⁇ to be set, this area being referred to as a sweeping mirror b sp .
  • 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 which can be changed by means of the adjusting device 16 and the associated size of the sweeping mirror b sp 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 probe body 22 comes into contact with the lateral surface 20 ⁇ of the roller broom, it is caused to vibrate by the bristles of the roller broom 14 running along the surface 32.
  • These vibrations can be accelerometer 30 ⁇ e.g. be recorded as structure-borne noise.
  • the occurrence of the signal change recorded by the accelerometer 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 surface 32 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.
  • measurements are expediently carried out at several measuring locations, for example at measuring locations a and b.
  • several, for example two, sensor devices 18 can be provided, or a single sensor device 18 can also be used, which is then moved axially to the different measuring locations, for example 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 sp 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 only brought to the lateral surface 20 ⁇ of the roller broom 14 at predetermined time intervals, and then withdrawn again. This also reduces the wear on both the probe body 20 ⁇ and the roller brush 14. Since the measured value acquisition takes up very little time, the measurements can be repeated at short time intervals, so that monitoring and measurement of the roller diameter 2r, adapted to the task, is possible while maintaining the advantage of low wear with increased brush wear.
  • 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 sp .
  • 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 sp can be derived from these variables in accordance with the formula mentioned above.
