  • the self-propelled floor milling machine is characterized by a monitoring system for monitoring the working process, which has a detection unit which is designed such that a physical quantity is detected, which is characteristic of a malfunction of the working process.
  • This disorder is characterized by the fact that during the processing of the traffic area with the work roll fragments are broken out of the traffic area, which apply a compressive force on the height-adjustable hold-down.
  • the compressive force exerted by the fragments on the movable hold-down means that the hold-down in a raised position relative to the traffic surface is pressed. As a result, the disturbance of the work process can first be detected.

Furthermore, this ensures that the fragments are successively crushed and not captured as a whole by the milling drum and accelerated in the milling drum housing. Overall, the applied pressure force thus leads to the fact that the milling process can be continued substantially without impairment despite the breaking out of large fragments or clods.
  • the contact pressure of the hold-down should preferably be such that the gap between the lower edge of the blank and the surface of the traffic area is as small as possible or the hold-down rests on the traffic surface to escape the milling material from the Fräswalzengephaseuse to prevent.

  • a significant advantage of the adjustment of the contact pressure of the blank holder according to the invention is that the increase of the contact pressure is fully automatic only when needed without any intervention of the machine operator in the control of the machine. The machine operator can thus concentrate on the actual control of the machine. The wear on the relevant components of the ground milling machine is significantly lower than when the contact pressure of the blank holder is permanently increased during the entire milling process.
  • the hold-down is designed such that it constantly rests with a predetermined force, in particular with its weight in a floating position on the traffic surface. Therefore, the hold-down is subject to some wear.
  • the adjustment according to the invention of the contact pressure of the hold-down device allows the operation of the hold-down device in the floating position with a reduced contact force on the traffic surface, if a clod formation does not occur.
  • the hold-down in the floating position can be easily raised against its weight, so that it slides with less force than its weight over the traffic area.
  • the contact force is only increased when a floe occurs. As a result, the wear on the hold-down can be reduced.
  • a further preferred embodiment of the invention provides that the device for height adjustment of the hold-down is designed such that on the hold-down against the pressure force directed contact pressure for a predetermined time interval is applied. After the specified time interval has elapsed, it can be checked whether disturbances in the milling process occur again when the contact pressure is reduced. Should it again come to disruptions in the milling process, the contact pressure is increased again. The hold-down device will therefore be operated with increased contact pressure only if a Schollen Struktur shows.
  • a particularly preferred embodiment provides that the device for adjusting the height of the hold-down is designed such that the contact pressure directed against the pressure force is increased as long as the detection unit detects disturbances of the working process.
  • the contact pressure can be increased gradually or continuously.
  • the hold-down in a floating position initially rest only with its own weight on the traffic surface. In a floe formation is then exerted by the device for height adjustment, an additional contact force on the hold-down.
  • the holddown initially rests with a lower weight than its own weight on the traffic area, d. H. the hold-down is relieved, is dispensed in a first step on the discharge of the hold and then a predetermined contact force is applied, which is optionally increased until it no longer comes to floe formation.

  • the recognition of the disturbance of the working process, ie the formation of floes, is also possible because different characteristic physical quantities are evaluated. If several physical values are the basis of the evaluation, the redundancy can be increased for the detection of the disturbance.
  • the detection unit has a measuring unit which is designed such that a movement of the blank holder is detected as a result of a compressive force acting on the hold-down, if broken out during the processing of the traffic area with the work roll fragments from the traffic area become.

  • the movement of the hold-down can be detected, for example, directly on the hold-down or parts connected to the hold-down or indirectly in the hydraulic system of the device for height adjustment of the hold-down.
  • the measuring unit for detecting the movement of the blank holder has a Wegumblensensor, which measures the distance to which the holddown against the traffic area due to the breaking out of fragments lifted from the traffic area becomes.
  • the evaluation unit of the detection unit is designed such that the amount of the distance by which the hold-down is raised, is compared with a predetermined limit, wherein the disturbance of the working process is concluded when the amount of the distance is greater than the limit.
  • the distance can be measured on the hold-down device itself or on components associated with the hold-down device. For example, if the hold-down is connected to a piston / cylinder arrangement, movement of the piston or cylinder of the piston / cylinder arrangement or relative movement of the piston and cylinder can also be detected.
  • a particularly preferred embodiment provides that the temporal change of the distance, d. H. the acceleration of the holddown is detected.
