Definitions
- the invention relates to an arrangement for fine positioning of coke oven machines.
- a coke plant usually consists of a coke oven, which is divided into several successive chambers is to operate them from the side and above with chamber doors closable openings are provided. At both Long sides and on top of the oven are on rails Movable operating machines arranged that are suitable are, each of the furnace chambers after opening the respectively assigned Chamber doors to operate, i.e. the chamber in question to feed and after the end of the coking process Pushing the glowing coke out onto a fire truck. To ensure trouble-free operation, is it is necessary to use the operating machines at the right time to position precisely.
- DE-OS 26 48 049 is a method for controlling and monitoring the operation of coke oven operating machines known with both the path detection of the operating machines such as their fine positioning and Tie monitoring is possible. To do this are at the breakpoints of the individual coke oven operating machines along their Roadway code plates mounted, their information content of reading devices attached to the machines in the corresponding position can be recorded. These code plates serve at the same time, the center of the respective furnace chamber for the purpose of fine positioning of the operating machines. From a comparison of a central control unit predetermined target goals with the actual positions of the operating machines become signals for the control of the travel drives derived, through which the machines exactly in the middle of the furnace Come to a standstill.
- the center detection of the individual furnace chambers is by additional magnets on the code plates and appropriately arranged magnetic receivers on the operating machines performed.
- the reading device gives positive or negative voltages that are dependent on the direction of travel Setpoints influence the speed control of the travel drives until until with the signal "O" the machine in the middle of the furnace is stopped.
- a positioning method using magnetic means has one in the zero range a relatively flat magnetic curve Field strength depending on the direction of movement and thus also the control voltage generated by the Hall generators.
- the present invention has for its object a Arrangement of the type mentioned in such a way that a millimeter-precise positioning of the operating machines in a given position despite the large amount of dust and heat is possible.
- Known code readers are the PP 2071 device and the predecessor device PP 2038, e.g. in the '82 catalog of photoelectrics Pauly GmbH is disclosed. There are possible uses for these devices known as the positioning of overhead cranes or shelf conveyors.
- Fig. 1 there is the positioning arrangement an operating machine from a position detection module 1, which is a signal generator 2 for path detection and an angular step signal generator coupled to the drive motor 3 are assigned. That from this position detection module 1 detected location signal is used both by an identification and positioning assembly 4 as well as one Lead setpoint generator 5 supplied. This in turn is with control electronics 6 for the drive motor 7 of the relevant Operating machine not shown connected. All units mentioned communicate via one Data bus 8 with a process computer, not shown.
- the identification and positioning assembly 4 is with one on the operating machine arranged signal transmitter 9 connected, which in connection with at the coke oven attached signal plates, not shown way of identification and description yet to be described Positioning signals generated.
- the Position detection module 1 After determining the respective location of the operating machine concerned by the Position detection module 1 generates this Location signal, which in the process computer with the location setpoint is compared. From these Both values will be the lead setpoint 5 a the direction of movement determining signal supplied. This gives the Control electronics 6 a corresponding Switch-on and direction of rotation command, its execution via the data bus 8 to the process computer is reported.
- the identification and positioning assembly 4 from the travel detection module 1 an enable command and directional information from the process computer.
- the signal generator 9 reaches a signal plate, controls the identification and positioning assembly 4 den Lead setpoint generator 5 for location-dependent Speed setpoint output and issued Start and stop commands. This is what happens Positioning with the help of each stop assigned identification codes during the breakpoint itself with the help of two positioning marks placed on each signal plate in collaboration with a corresponding number of signal generators 9 assigned light barriers to be described Way is determined.
- the signal generator is 9 the operating machine to be controlled and the marking plate of the associated furnace chamber.
- the U-shaped designed signal generator 9 has in one its legs infrared light transmitter 11, 12, 15 and infrared light receiver in the opposite leg 13, 14, 16.
- One sender and one receiver form an infrared light barrier.
- the arrangement is such that two of these Photoelectric sensors with transmitters 11 and 12 as well the assigned receivers 13 and 14 for exact positioning and the remaining 8, opposite the above arranged upwards Photoelectric sensors, with the transmitters 15 and the recipients 16 of the identification of the the breakpoint assigned to the respective furnace chamber serve (reading device).
- the marking plate 10 has correspondingly arranged, markings impermeable to infrared light.
- the both, the support body 17 of the marking plate 10 slightly higher markings on the side 18, 19 are arranged so that they in the Stop position the two positioning light barriers 11, 13 or 12, 14 at least partially interrupt. At least one of these marks is in the direction of movement of the marking plate 10 for adjustment purposes with an elongated hole provided so that after loosening an adjusting screw 20 this marker around a certain one Amount is adjustable in the direction of movement.
- Above these position marks are the Top edge of the support body 17 projecting outside Identification marks 21 arranged. They are placed so that they are at the breakpoints the identification light barriers assigned to them 15, 16 completely interrupt. By the number and arrangement of these identification marks can give each stop one certain coding can be assigned so that an appropriately programmed read memory is able to reach the breakpoint concerned identify.
- Each of the infrared transmitters and infrared receivers is with the identification and positioning assembly 4 connected, which the of the Recipients 13, 14, 16 transmitted identification and positioning signals in connection evaluates with the central process computer.
- FIG. 3 shows a functional diagram from which the principle of operation of the arrangement emerges.
- a positioning light barrier 22 consisting of the positioning transmitter 23 with the transmitter diode 24 and the optical lens 25 and the positioning receiver 26 with the receiver diode 27 and the optical lens 28, and an identification light barrier 29, consisting of the identification transmitter 30 with the transmitter diode 31 and the optical lens 32, and the identification receiver 33 with the receiver diode 34 and the optical lens 35 shown.
- the transmitters and Receiver of the aforementioned light barriers 22, 29 are connected via a cable 36 to the identification and positioning assembly 4 connected.
- This has a logic module 37, a read memory 38 with a position indicator 39, one Position evaluation module 40, one automatic read monitoring module 41 and a power supply part 42.
- the one assigned to this light barrier Positioning recipient transmitted this via the position evaluation module 40 to the process computer via line 44 supplies a start marker pulse, and the logic module 37 of the identification and Positioning module 4.
- the position evaluation module performs the Process computer via line 46 a «pre-position pulse »To what this the Command setpoint generator 5 for a changeover to "creep speed" during one of the position detection module 1 given route the operating machine causes.
- the position evaluation module receives 40 a corresponding Impulse of the assigned positioning receiver and reports this to the logic module 37, which in turn read memory 38 and Identification transmitter and the identification recipient starts up. Then the lead Identification receiver the read memory 38th their identification impulses to who the read Coding via the data bus 47 to the process computer passes on.
- the process computer reports this to the logic module 37, the position evaluation module 40 resets so that no shutdown the drive of the operating machine concerned takes place, which eliminates the "creep speed" and the operating machine is yours Can continue with normal driving.
- the position evaluation module 40 when reaching the target position line 48 sends an "in-position signal" to the Process computer.
- the position evaluation module guides the receiver 40 the management setpoint generator 5 a stop signal, which in turn via the control electronics 6 the drive motor 7 the operating machine stops.
- read memory 38 enters its contents in a Position indicator 39, which each reached Displays position in digital form.
- the logic module receives 37 a release from the process computer and renewed directional signal. As soon as one of the positioning light barriers again is free, the position evaluation module gives 40 via line 48 a «post-position pulse »To the process computer. At the same time the automatic read-monitoring module 41 released, the reading device 15, 16th constantly checked for errors when both positioning light barriers 11, 13 and 12, 14 not be covered. If an error occurs, be Position evaluation module 40 and read memory reset and the error to the process computer reported. This decides whether the Drive continues or is interrupted.
- the position marks in the direction of movement adjustably arranged on the support body 17 2, the position marker 18 provided with an elongated hole.
- the responsiveness and tolerance of position marks to the desired value adjust and thus also the hysteresis, d. H. the deviation of the target position depending optimize from the direction of travel, d. H. the cheapest value depending on the different Operating machine parameters to choose.
