This allows the sweepings to reach the sweeping roller below the at least one flap and then be transported accordingly (particularly after the at least one flap has been returned to the second position) into the at least one sweepings container.
  • the solution according to the invention allows, in addition to “dust sweeping”, also "light waste” to be removed from the floor to be cleaned. By temporarily lifting the at least one flap and holding it in at least one third position, this light waste can reach the sweeping roller and from there be transported into the at least one sweeping waste container.

  • the second actuator device 156 is mechanically coupled to the first actuator device 122 via the bridge element 114. Activation of the second actuator device 156 causes a movement of the first actuator device 122 as a whole and thus a pivoting of the flap 92 about the pivot axis 96. However, the pivoting is such that the passage 152 is opened and the third position 150 is below the first position 142.
  • the second actuator device 156 is an electric motor, and in particular a linear motor 158.
  • This linear motor 158 has a linearly movable rod 160.
  • the rod 160 is coupled to the bridge element 114 at a distance from the pivot bearing 116.
  • a displacement position of the rod 160 determines a rotational position of the bridge element 114 on the pivot bearing 116.
  • the second actuator device 156 with its linear motor 148 is not active and the rod 160 is positioned so that the bridge element 114 is in its initial position 120 ( Figures 3 , 4 ).
  • the rod 160 is moved and pivoted, for example, in the direction of the sweeping roller 26 (compare Figure 5 ) that the first actuator device 122 with the base 126 and the movement element 128 is moved toward the sweeping roller 26.
  • This causes the flap 92 to be raised from the second position 146 and brings the flap into the third position 150 with the passage 152 open.
  • the third position 150 of the flap 92 was described above. It is generally possible for there to be exactly one third position 150, or for there to be multiple third positions 150. If there are multiple third positions 150, these can be set in steps or continuously.
  • the second actuator device 156 is arranged above the first actuator device 122 with respect to a height direction transverse to the installation plane 18.
  • the first actuator device 122 and the second actuator device 156 can be activated by the operating device 52.
  • the operating device 52 is designed such that permanent operator intervention is necessary to maintain the third position 150.
  • the operating device 52 comprises a button 162 (see Figure 1 ), which is assigned to the second actuator device 156.
  • the button 162 is not actuated, the bridge element 114 is in its initial position 120.
  • the second actuator device 156 is activated accordingly, displacing the rod 160 and pivoting the bridge element 114, as described above.
  • the button 162 must remain pressed, and to maintain the third position 150, the button 162 must also remain pressed.
  • the rod 160 returns to its initial position (automatically) and the bridge element 114 automatically moves to its initial position 120.
  • the flap 92 thereby automatically moves to the second position 146. Therefore, without active operator intervention on the button 162, the flap 92 does not remain in the third position 150.
  • the sweeper 10 functions as follows: During a non-cleaning trip, for example to or from a job site, the flap 92 is in the first position 142. This closes the opening 82 by the flap 92 (compare Figure 4 ).
  • the flap 92 is moved by the operator to the second position 146 (compare Figure 3 ). Sweepings can then be transported by the sweeping roller 26 (which is lowered onto the floor 16 to be cleaned) through the flap into the sweepings container 44.
  • a sensor device 164 (see Figure 3 ) is positioned, which monitors the space 148 for the accumulation of "light waste."
  • the sensor device 164 is, for example, an optical sensor device or a camera sensor device.
  • the sweeper 10 comprises a control device 166 (see Figure 1 ), which is signal-effectively coupled to the sensor device 164.
  • the control device 166 evaluates, in particular, signals from the sensor device 164 regarding an accumulation of "light waste" in the space 148. If an accumulation or excessive accumulation is detected, the control device 166 controls the second actuator device 156, which then briefly moves the flap 92 into the third position 150 in order to open the passage 152 to the sweeping roller 26.
  • the third position 160 is held for only a relatively short period of time, for example, 10 s, 20 s, or 30 s. Subsequently, the second actuator device 156 is controlled such that the flap 92 automatically returns to the second position 146.
  • FIG. 7 Another embodiment of a sweeper 168, which is shown in the Figures 7 and 8 is basically designed the same as the sweeper 10.
  • a second actuator device 170 is provided, which also acts on a bridge element 114', wherein the second actuator device 170 is positioned in particular between the first actuator device 122 and the installation plane 18.
  • the second actuator device 170 is, for example, an electric motor which acts directly on the pivot bearing 116 in order to pivot the bridge element 114'.
