Milling Machine, In Particular Surface Miner, And Method For Mining Milled Material Of An Open Cast Surface

Abstract

In a method for milling an opencast mining surface or for milling off layers of an asphalt or concrete traffic surface with a milling machine removing the ground surface, by milling the ground surface along a predetermined milling track and by transporting the milled material via a conveying device to at least one container of a truck that travels along next to the milling machine, a relative position between the container and the conveying device is automatically controlled to regulate the loading of the container.

What is claimed is: 
     
         1 . A method of controlling a loading process of a transport container of a transport vehicle by a milling device during a milling operation, wherein the milling device comprises a conveyor, via which milled material is transported to the transport container during a milling operation of the milling device, and a control unit, comprising the steps:
 a) detecting the relative position of the transport container in a loading range of the milling device via a sensor device;   b) starting the loading process by starting up the conveyor;   c) monitoring the relative position of the transport container via the sensor device; and   d) issuing a signal when a predetermined fill level of the transport container is determined, for stopping the loading process.   
     
     
         2 . A method according to  claim 1 , wherein the control unit controls driving movement of the transport vehicle during the loading operation. 
     
     
         3 . A method according to  claim 1 , wherein the control unit considers at least one of the following operating parameters of the milling device for controlling the loading process:
 speed of the milling device during the milling operation;   milling depth of a milling rotor; and   delivery speed of a conveyor belt of the conveyor.   
     
     
         4 . A device for controlling a loading process of a transport container of a transport vehicle by a milling device during a milling operation,
 wherein the milling device comprises a conveyor via which milled material is transported into the transport container during a milling operation of the milling device,   wherein the device comprises a sensor device designed for detection of a relative position of the transport container to the milling device, and   in that the device comprises a control unit, which controls the loading process based on the relative position of the transport container to the milling device detected by the sensor device.   
     
     
         5 . A milling machine, comprising a device according to  claim 4  for implementing a method according to  claim 1 . 
     
     
         6 . A milling machine according to  claim 5 , wherein the milling machine comprises a road milling machine or a device for removal of soil material.
