Definitions
- the invention relates to a control system for the automatic control of a movable bucket wheel device for the removal of stockpiles and / or for stockpiling bulk goods, wherein the bucket wheel device for receiving the bulk goods has at least one bucket wheel, at least one measuring device is provided for measuring the stockpile and the bucket wheel device depending on the measured and / or processed measurement data can be moved automatically to the desired dismantling and / or hold position.
- the bucket wheel device for receiving the bulk goods has at least one bucket wheel, at least one measuring device is provided for measuring the stockpile and the bucket wheel device depending on the measured and / or processed measurement data can be moved automatically to the desired dismantling and / or hold position.
- Invention a method for the automatic control of a movable bucket wheel device, in particular with the aid of the control system mentioned at the beginning, wherein an automatic control of a movable bucket wheel device takes place for the removal of stockpiles and / or for stockpiling bulk goods, the stockpile shape being recorded with the aid of at least one measuring device is and the paddle wheel device is automatically moved to the desired dismantling and / or hold position depending on the measured and / or processed measurement data.
- Handling facilities are particularly warehouse and transport systems optimized for inventory and lead times. Inexpensive and future-oriented solutions take particular account of the integration into the automation technology, so that inexpensive and simple handling can be implemented in later operation. It should be noted in particular that
- Bucket wheel devices generally run in 3-shift operation, that is, in the case of manual control of such a bucket wheel device, corresponding wages have to be paid by the employer, the operation of such a bucket wheel device is therefore associated with high costs.
- a paddle wheel device is known that is designed to break down, in particular, compacted heaps or to hold bulk goods.
- the bucket wheel device also called “bucket wheel excavator”, has a front boom, at the front end of which the bucket wheel is located, and a pylon, which is tower-like is executed on.
- a counterweight is provided that is arranged on the side of the pylon opposite the front boom, namely on a rear boom.
- the front area of the front boom is connected to the counterweight via suspension cable elements via the upper section of the pylon. The forces that occur when the bucket wheel is loaded with bulk goods on the front boom or on the bucket wheel device are compensated accordingly via the counterweight.
- the known paddle wheel device described here has a control system for the automatic control of the movable paddle wheel device.
- a measuring device is provided for measuring the shape of the stockpile, namely the surface profile of the stockpile. Since the bucket wheel device itself is designed to be movable, that is to say has a corresponding drive system, the bucket wheel device is moved to the desired dismantling and / or holding position depending on the measured and / or processed data that the measuring device has determined, and preferably in such a way that the paddle wheel located at the front end of the front boom is positioned at the desired dismantling or stopping position.
- the bucket wheel device itself is moved, and on the other hand the front boom of the bucket wheel device is moved in such a way that the bucket wheel is positioned in the desired height position and in the desired lateral position for removing or heaping up the stockpile.
- the bucket wheel device known here in the prior art is moved depending on a surface profile of the stockpile that is determined or calculated with the aid of the measuring device, or individual movable components of the bucket wheel device, which are referred to as combination devices, for example, are moved.
- the measuring device used here is designed as a 2-D scanner and scans the surface of the heap.
- the measuring device is arranged in the front area of the front arm of the bucket wheel device.
- the known paddle wheel device In order for the stockpile shape, ie the surface profile of the stockpile, to be ascertained, the known paddle wheel device must be moved along the stockpile, the front boom practically “running over” the stockpile and the measuring device scanning the surface while passing over the stockpile Before starting the work process, the paddle wheel device must first be subjected to a separate measurement run with the help of the travel path of the paddle wheel device, the position of the lifting mechanism, the pivoting mechanism and the Undercarriage, the respective positions of which are determined by separately provided angle sensors or separate sensors, the position of the measuring device can also be determined, among other things. This measuring device scans the stockpile shape during the measurement run.
- a 3-D stockpile model is calculated from the measurement data of the measurement device and the measurement data of the angle sensors provided on the travel swiveling and lifting mechanism and with the aid of a 2-D converter.
- the separately provided control system continuously polls the values of the angle transmitters and belt scale measurement values for the bulk goods that have been removed, that is to say dismantled.
- the control calculates a provisional stockpile model that is continuously updated in accordance with the measured excavation quantity or the hold-up quantity of the bulk material, so that preferably no separate measurement runs with the bucket wheel device have to be carried out in order to determine the surface profile of the stockpile.
- the stockpile shape is first of all determined with the aid of a measurement run of the paddle wheel device of the 2-D scanner, the dismantling or stopping process then being started and the corresponding measured values , in particular angle encoder signals and quantity values for the mined or piled up bulk material, then the control system calculates a provisional stockpile model.
- the control system known in the prior art or the method known here for the automatic control of a paddle wheel device has not yet been optimally designed.
- a measurement run of the bucket wheel device or a combination device for recording or determining the shape of the stockpile is always necessary, since the measuring device arranged in the area of the front boom must be moved over the stockpile in accordance with the length of the stockpile, so that the 2-D Scanner can also capture the stockpile shape.
- the movement of the entire bucket wheel device in particular the movement of the travel, lifting and swiveling mechanism, must be carried out. with the help of the angle encoder, i.e.
- the movement of the paddle wheel device about its two axes of rotation and the movement of the paddle wheel device vzw. along a rail along the heap by separate sensors, which measure the distance, are permanently determined so that on the one hand the position of the measuring device can be determined and on the other hand the heap shape or the heap model can also be calculated from the measurement data.
- the bucket wheel device is then automatically moved to the desired dismantling and / or hold position, so that the bucket wheel of the bucket wheel device begins, for example, with the stockpile being dismantled, based on that in the control unit Stored "recorded stockpile model".
- This stockpile model is then updated with the aid of further measurement data which are determined, in particular the quantity of bulk material arriving at the conveyor system or conveyed away from the conveyor system (for example the amount of hard coal) is recorded by appropriate sensors and thus the conveyor belt measurement values and
- further measurement data which are determined, in particular the quantity of bulk material arriving at the conveyor system or conveyed away from the conveyor system (for example the amount of hard coal) is recorded by appropriate sensors and thus the conveyor belt measurement values and
- the stockpile removal is therefore controlled on the constantly updated theoretical "stockpile model”.
- the shape of the stockpile can change during operation of the bucket wheel device, for example during rainfalls due to natural slipping processes or the like. Furthermore, slipping or slipping can be triggered by the dismantling process itself.
- a currently changing stockpile shape cannot be detected immediately, in particular cannot be recorded when, for example, the paddle wheel device is at a standstill, ie is not operated, since the measuring device does not pass over the stockpile. Due to the changing stockpile shape, in particular due to natural slipping processes, it can happen that the paddle wheel of the paddle wheel device assumes a starting position, for example, which is not optimal. This harbors dangers for the corresponding hydraulic system and also for the paddle wheel device itself (risk of tipping over). In the end, the known method or the known control system is not optimal here, since, during operation of the bucket wheel device, for example, slipping off of certain partial areas of the stockpile is not detected.
- the invention is therefore based on the object of To design and develop the system or the method mentioned at the outset in such a way that the control of a bucket wheel device is optimized, in particular the positioning of the bucket wheel vzw. is optimized while avoiding dangers and the necessary initial measurement run of the bucket wheel device for detecting the shape of the stockpile is also avoided.
- the task outlined above is now achieved in that the control system and the measuring device are designed or implemented in such a way that, regardless of the operation of the paddle wheel device, permanent detection of the current stockpile shape is guaranteed, namely a current change the stockpile shape can be detected at least in a certain surrounding area of the impeller.
- the current stockpile shape is recorded, namely a current change in the stockpile shape is detected at least in a certain surrounding area of the paddle wheel.

- At least one measuring device 11 is provided for measuring the heap 9. With the help of the control system 10 and the measurement data measured by the measuring device 11, the bucket wheel device 1 is then automatically moved to the desired dismantling and / or holding position, in particular the bucket wheel 6 is positioned accordingly.
- control system 10 and the measuring device 11 are designed or designed such that a permanent detection of the current stockpile shape is guaranteed, regardless of the operation of the bucket wheel device 1, namely a current change in the stockpile shape at least in a certain surrounding area of the impeller 6 can be detected. Consequently - in accordance with the method according to the invention - a permanent detection of the current stockpile shape is ensured, regardless of the operation of the bucket wheel device 1, and thus a current change in the stockpile shape - at least in a certain surrounding area of the bucket wheel 6 - is recorded. Due to the permanent recording of the stockpile shape, which corresponds to the actual circumstances, namely because the stockpile shape is scanned permanently, i.e.
- the paddle wheel 6 can always be optimally positioned at the desired opening or dismantling position. While in the prior art scale measurement values of the bulk goods dismantled via the conveyor belt had to be determined and the provisional “stockpile model” was thereby calculated, the components necessary for this in the control effort are dispensed with or a more precise control by the control system according to the invention is now eliminated or procedure possible. 1 and 3, the measuring device 11 is arranged on the pylon 3, namely at the upper end of the pylon 3.

- the first GPS position receiver 12a is arranged on the front boom 2 of the bucket wheel device 1. It is conceivable that in addition to the first GPS position receiver 12a, namely shortly behind the paddle wheel 6, a video camera system is also arranged which, for example, can in turn be connected to an external control station. However, this is not absolutely necessary here, since the paddle wheel device 1 is one by one Control center independent control system 10, as shown in Fig. 2, and here a separate control unit 10a and a separate control computer 10b are provided for the paddle wheel device 1.
- the control system 10 here has the control unit 10a, a separate control computer 10b and corresponding control lines 10c.

- the control system 10 or the measuring device 11 and the associated components of the control system 10 are designed such that the heap shape is recorded in real time. It is no longer necessary to run the entire stockpile 9 in the longitudinal direction.
- the movements or positions of the paddle wheel device 1 and its components, in particular the Movements of the paddle wheel device 1 about its three axes of rotation are recorded with the aid of the GPS system.
- the stockpile shape can always be continuously scanned or determined and the generation of a further scanning axis, such as in the 2-D scanner known in the prior art, is no longer necessary.
- the stockpile shape is always up-to-date calculated using the control system 10, in particular the control computer 10b, from the measurement data supplied here by the 3D scanner 11 and the GPS system.
- FIG. 4 finally shows the surface profile of a stockpile 9, which is calculated with the aid of the control computer 10b and is output in a two-dimensional color representation on a screen 16.
- This presentation has proven to be very advantageous. Individual segments 17, vzw. in different colors on the screen 16, here partially characterized by different hatching.
- Such a screen 16 could, for example, be provided in an external control station which is provided for the control or monitoring of a plurality of bucket wheel devices 1.

- an inclination angle sensor 14a is provided here, which is likewise connected in terms of circuitry to the control computer 10b or the control unit 10a. If the inclination angle sensor 14a determines a specific inclination angle of the bucket wheel device 1, the operation is immediately stopped, in particular the bucket wheel 6 is switched off. The measurement data of the inclination angle sensor 14a are compared with the measurement data of the GPS system.
- the angle of inclination sensor 14a determines the angle of inclination of the bucket wheel device 1, in particular the inclination of the upper area or part of the bucket wheel device 1, and therefore also the inclination of the boom 2, on the other hand, this inclination can also be determined accordingly with the aid of the first and second GPS position receivers 12a and 12b and the control computer 10b. If the measurement data differ from one another here, this shows that either the inclination angle sensor 14a or the GPS system is not functioning properly. In this case, the control system 10 is designed such that the bucket wheel device 1 is also switched off, so that a safety system for the bucket wheel device 1 is implemented.
- the control system 10 is now designed so that at least a relatively large area can be detected using the measuring device 11.
- detection of the current stockpile shape in the area of the front boom 2 and detection of the surrounding area of the rear boom 8 is ensured.
- the boom 8, in particular the counterweight 4 provided here on the rear boom 8, can be moved, in particular pivoted, without risk.
- the front boom 2 or rear boom 8 is not pivoted with the aid of the control unit 10a or the control computer 10b.
- Measuring device 11 can therefore, especially since it is arranged at the upper end of pylon 3, "scan" a relatively large area around bucket wheel device 1, so that the safety aspect during operation of bucket wheel device 1 is significantly increased. LIST OF REFERENCE NUMBERS
