Definitions

  • the invention relates to a method for controlling a loading process of a transport vehicle with milled material, a device for carrying out such a method and a milling device, in particular road milling machine, with such a device.
  • Milling devices are known from the prior art which have a milling rotor carried by a machine frame and arranged transversely to the working direction. In milling operation, such milling devices travel over the ground, wherein the milling rotor dips into the ground and mills soil material through the processing tools arranged on the rotating milling rotor. In milling operation, the milling device thus moves in the working direction and passes over the soil to be processed.
  • Typical applications of such milling devices include road construction and road construction, for example in the form of road milling, and the degradation of soil material, for example in open pit mining.
  • Such milling devices are preferably also designed as self-propelled machines, which can be dispensed with separate towing vehicles.
  • milling devices An essential aspect in the operation of such milling devices is the handling of the milled material, ie the milled from the milling rotor material.
  • a suitable transport device for example a lorry.
  • the milling device usually has a conveying device, via which the milled material is transported in the milling operation of the milling device from the area of the milling rotor to the transport container of the transport vehicle or can be promoted.
  • Different embodiments are known with regard to the specific arrangement of the conveyor in relation to the transport vehicle.
  • the milled material transported to the rear (“backloader”) or to the side (“side loader”), especially for milling machines designed as a road milling has a forwardly directed conveyor belt (“muzzle”) proved to be particularly suitable.
  • the latter has the advantage; that the transport vehicle can drive during the milling work in front of the milling device on the not yet milled ground.
  • this load variant however, the milling guide usually before increased demands.
  • the visibility of the preceding transport trucks are poor and the router operator, for example, can not fully see the loading trough. Even the driver of the transport truck can not see the loading belt.
  • the milling leader is responsible for a safe work process, especially with regard to traffic safety and personal safety.
  • the milled material often milled road surface, on a comparatively high density, so that it can quickly come to overload situations.
  • the transport trucks usually used here move at speeds of up to 100 km / h, so that overloaded vehicles can pose a particularly high security risk.
  • the transport vehicle Due to the fact that the milling device is usually in driving mode during working or milling operation, i. moves in the direction of travel, the transport vehicle often can not persist in one place over the entire loading process away. Rather, it must move with the milling device in the working direction in order to remain in the loading range of the conveyor. Since the milling device frequently moves comparatively slowly in milling operation, a repetitive approach and stop of the transport vehicle has proven itself, wherein at the same time, in particular, a uniform loading of the transport container of the transport vehicle can be achieved. This process will be explained further below by way of example with reference to the operation of a front loader road milling machine.
  • the minimum distance is corresponding to the distance at which the conveyor just drops the milled material in the front region of the transport container or in which the milling device does not yet collide with the transport vehicle, depending on which distance is greater.
  • the machine operator signals with the command "depart" that the loading process is completed. Then the loaded transport vehicle leaves.
  • This type of loading process makes a total of enormous demands on the operator of the milling device, in addition to the milling process (especially observation of the milling edge, operation and control of the machine during the milling process and locating the environment of the machine) always the loading process or the relative position between the transport vehicle and must observe the milling device. This leads to a considerable burden on the machine operator.
  • EP 2 298 997 A2 discloses a level gauge of a forage harvester having the features of the preamble of claim 1, which is for measuring and displaying a remaining filling potential a target area is provided. At the outlet nozzle a 3D camera is provided, which serves as a 3D sensor. The image data generated by this 3D sensor are transmitted to a monitor, which serves a vehicle driver to monitor the loading process.
  • the object of the invention is now to provide a way to relieve the machine operator during the working operation of the milling device and the simultaneous loading of the transport vehicle.
  • the object is achieved by a method for controlling a loading operation of a transport vehicle with milled material, with a device for carrying out such a method and with a milling device, in particular a road milling machine, according to the independent claims.
  • Preferred developments are specified in the dependent claims.
  • the basic idea of the invention lies in the fact that the machine operator with the embodiments according to the invention is relieved of the necessity of continuous observation of the relative position of the transport container of a transport vehicle in relation to the milling apparatus and this process, at least in essential parts, runs automatically according to the invention. Accordingly, the operator no longer has to continuously ensure that the transport vehicle is always in a position suitable for loading during the milling operation of the milling device and can accordingly concentrate on carrying out the milling work itself.
  • An essential aspect of the invention resides in a method for controlling a loading process of a transport container of a transport vehicle, which is loaded by a milling device in the milling operation, wherein the milling device comprises a conveyor via which milled material is conveyed into the transport container during the milling operation of the milling device.
  • the method according to the invention comprises the steps of a) detecting the relative position of the transport container in the loading area of the milling device by means of a sensor device, b) starting the loading process by starting the conveyor, c) monitoring the relative position of the transport container by means of the sensor device and preferably also controlling the loading process depending on the relative position of the transport container and d) outputting a signal to the machine operator of the milling device when a desired filling of the transport container is detected or when the sensor device detects a removal of the transport container from the loading area.
  • the output of the signal according to step d) For example, by means of an optical and / or acoustic signal and / or also include an automatic stopping of the loading process.
  • the inventive method is thus characterized in an essential aspect by the monitoring of the transport container by a sensor device, which is designed for detecting and tracking the position of the transport container and preferably also for monitoring the level or for monitoring to achieve a desired filling during the loading process.
  • a sensor device which is designed for detecting and tracking the position of the transport container and preferably also for monitoring the level or for monitoring to achieve a desired filling during the loading process.
  • the loading area of the milling device is the area in which the conveyor can convey or deposit milled material obtained during the milling process.
  • the loading area is, for example, when using a arranged on the milling conveyor belt as a conveyor in other words the discharge area of the conveyor belt.
  • the loading area shifts accordingly depending on the height and other factors, such as the rotational speed of the conveyor belt of the conveyor belt. Only when the loading area is above the transport container of the transport vehicle, the milled material is thus dropped into the transport container.
  • the relative position according to the method refers to the position of the transport container in relation to the milling device and especially in relation to the conveyor of the milling device.
  • the sensor device is designed in such a way that it can determine the presence of at least one subarea of the transport container in the loading area for receiving milled material. Specific embodiments of the sensor device will be described in more detail below.

  • three-dimensional information for example the distance of the loading area to the transport container in the vertical direction, can be taken into account in addition.
  • the loading process is started by putting the conveyor into operation. This can be done automatically, for example.
  • a start or release circuit can be enabled, which allows a manual start of the loading process by the machine operator.
  • Under commissioning of the conveyor falls according to the invention even signaling to the machine operator, which has determined the sensor device that the loading area is positioned above the transport container.
  • the coordination between the steps a) and b) takes place via a control unit, which is functionally connected to the sensor device and optionally further devices, such as the release circuit, the milling device.
  • a functional connection exists when communication between two elements is possible via the connection and, in particular, data and / or control commands can be received and / or sent.
  • a functional connection thus comprises, in addition to a mechanical connection, also line connections, for example for the transmission of electrical or optical signals, and also wireless connections, for example radio connections.
  • the milling device moves on the preciselyfräsenden underground.
  • a continuous monitoring of the relative position of the transport container to the milling device or to the loading area of the conveyor takes place by means of the sensor device.
  • the essential element of this step is thus that the sensor device continues to check continuously to what extent the loading area of the conveyor is located at least over a partial area of the transport container and the milled material is correspondingly dropped into the transport container.
  • a signal is output, for example optically, acoustically and / or in the form of at least one control function, if a nominal filling has been reached or the loading area is not more completely overlaps with the transport container or with the receiving opening of the transport container.
  • the output of a signal is thus to be understood broadly and includes all measures which are suitable to alert the operator to the situations "target filling reached” and / or "transport container removed from loading area”.
  • By controlling an optical and / or acoustic signal device it is for example it is possible to alert the operator to the achievement of the required filling or to the removal of the transport container from the loading area.
  • the outputting of a signal can alternatively or additionally also be pure control functions.
  • control functions for the loading process first of all all measures can be taken which have an influence on the loading process in some form, in particular, in particular, the commands "conveyor on” and “conveyor off”. It goes without saying that different signals or control functions can be triggered simultaneously. Overall, a considerable relief in particular of the milling guide is made possible because he no longer has to continuously observe and control the loading process of the milled material on the transport vehicle.
  • the loading process is preferably stopped according to the method when a desired filling of the transport container is determined or as soon as the sensor device detects a removal of the transport container from the loading area.
  • the nominal filling is that filling which must not be exceeded in order to avoid overloading the transport vehicle.
  • the desired filling may be defined by the filling volume of the transport container and / or in particular by the filling weight of the transport container.
  • the achievement of the desired filling can be determined concretely in different ways. Ideally, this is also done with the help of the sensor device, although other methods, such as weight-based methods, are possible.
  • a removal of the transport container from the loading area can for example be present when the distance between the milling device and transport vehicle is too large.
  • the specific implementation of the position determination of the transport container by the sensor device may vary.
  • corresponding marking elements may be present on the transport container, which selectively recognizes the sensor device and thereby makes inferences about the current position of the transport container.
  • These may be, for example, suitable reflectors and / or transponder elements.
  • the sensor device can be designed in particular in such a way that it covers the upper edge of the transport container or detects its peripheral edge, as is possible for example with known optoelectronic devices.
  • this has the advantage that the transport container does not have to be designed in a special way; after all, the use of upwardly open and peripheral edge transport containers is absolutely customary, and, on the other hand, a multiplicity of devices are known, via which such "edge recognition" is known. can be reached quickly.
  • the sensor device in such a way that it always detects the entire transport container or at least the peripheral upper edge of the transport container and monitors its relative position. Often this is not possible. This may be the case, for example, due to the specific arrangement of the sensor device and / or the dimensions of the transport container and / or the sensor field (area which the sensor device can detect). However, it has been shown that the detection of partial areas of the transport container by the sensor device is already sufficient for carrying out the method according to the invention. In this case, it has proved to be advantageous if, during monitoring of the relative position of the transport container with the aid of the sensor device, the following operations occur: 1.
  • the basic concept in this embodiment thus consists in a virtual division of the transport container into a plurality of subregions, which are each monitored by the sensor device.
  • the control unit creates a history of the subareas that have already been recorded, and finally determines the total filling of the transport container from the synopsis of the currently determined subarea and the additional subsections. Due to the fact that, in milling operation, the distance between the milling device and the transport vehicle changes between maximum approach in the loading area and maximum distance in the loading area, the sensor device is thus repeatedly guided with its detection area over the entire transport container, in particular its upper edge.
  • the method according to the invention solves this problem in that it subdivides the transport container into a plurality of subregions and uses the filling states respectively determined for the subregions to determine the overall filling state of the transport container.
  • the most up-to-date data record is always used, so that, for example, if the first sub-area has been checked by the sensor device three times in succession, the last and thus most recently determined filling state is used to determine the total filling.
  • these steps take place, for example, by a control unit, which receives the corresponding data from the sensor device, deposited and updated with respect to the respective subarea.
  • Essential criteria for a perfect filling of the transport container with milled material on the one hand as lossless promotion of the milled material in the transport container using the conveyor and at the same time the maximum and / or uniform loading of the transport container with milled material to an efficient removal of the milled material from the workplace to reach.
  • the strategy for filling the transport container can provide a load from behind or from the front or preferably to protect the transport vehicle evenly over the transport container.
  • the invention proposes in this context that during the step c) (monitoring of the relative position ...) and in particular during the control of the loading process (which, for example, during the step c) can take place) detecting the discharge path of the Milling material dropped from the conveyor into the transport container according to the invention together with at least the rules of the discharge of the discharge path, in particular by regulating the working speed of the conveyor, by a height adjustment of the conveyor and / or by adjusting the attitude angle of the conveyor, and optionally in addition to the Rules of the side deflection of the discharge path relative to the transport container by a lateral adjustment of the conveyor takes place.

  • the discharge point of the material to be milled in the transport container in different ways and by adjustments of the conveyor.
  • the sensor device detects the discharge path of the material to be milled and at least one virtual discharge point, in particular at the level of the upper edge of the transport container determined. It is important that the milled material can no longer fall out of the transport container below this virtual discharge point, which is the case below the upper edge of a transport container, for example.
  • a fine control of the discharge track or an influencing of the virtual discharge point, in particular in the surface of the upper edge of the transport container carried out in various ways and ways.
  • a lateral deflection of the conveyor for lateral adjustment of the discharge path can be triggered so that the discharge point of the milling material in the working direction moves to the right or to the left.
  • Side deflection thus refers to a change of the discharge track to the sides to the right or left.
  • the discharge of the discharge track for example, by increasing or decreasing the rotational speed of a conveyor belt or the height adjustment or the position adjustment of the conveyor take place.
  • a particularly uniform distribution of the milled material in the entire transport container can be achieved in this way. It goes without saying that to trigger the individual control functions suitable actuators are present and are controlled by the control unit.
  • the control unit is preferably designed in this case in such a way that it controls a signaling device depending on the degree of loading of the transport container and / or the distance between the milling device and the transport vehicle, which at least in each case a signal for the instructions "drive forward", “ stop “and” drive off "indicates.
  • the instructions are preferably carried out in a perceptible by the driver of the transport vehicle manner.
  • the control unit is thus able via the signal device to regulate the relative position between the transport vehicle and the milling device by the automatic output of appropriate commands to the driver of the transport vehicle.
  • the machine operator of the milling device for example, no longer has to take care that the transport vehicle advances and stops in time during the loading process and thus moves in a suitable manner with the milling device driving in the milling operation.
  • This embodiment of the method according to the invention is characterized in that the driver of the transport vehicle its driving commands during the loading process automatically receives from the controlled by the control unit signaling device.
  • control unit controls the travel movement of the transport vehicle directly during the loading process, for example via corresponding remote control devices or via a mechanical coupling, which is designed in such a way that it can also be controlled by the control unit for distance regulation.

  • the transport vehicle When forward or in the direction of loading loading milling devices, the transport vehicle is, for example, initially at a maximum distance. The maximum spacing is present when the milled material is just dropped in the rear of the transport container.
