Abstract

PURPOSE:To stop a working machine at a predetermined position of an oven to be operated with a predetermined stopping accuracy, by detecting an oven number and oven core information stored in an information memory provided in each oven by means of a reader mounted on a coke oven working machine, and outputting the oven number and oven information. CONSTITUTION:A coke oven working machine 6 having a reader 5 mounted thereon is provided on rails 7 laid on in a direction parallel to a group of coke ovens 1 comprising several hundreds of ovens 2 provided with an information memory 3 storing the oven number and oven core information. The oven number and the oven core information stored in a storage 8 of the memory 3 are output as a medium 4 from a data transmitting section 9. A sensor 11 of the reader 5 receives the data. An operation is conducted in a controller 12 to output an oven signal 14, and an error of a distance between the machine 6 and the oven core in the direction of travel is measured. When the error is within a predetermined position accuracy, an oven core signal 15 is output to stop the machine 6.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a coke extruder, a coal charging vehicle 1. The present invention relates to a furnace number and furnace core detection device necessary for stopping coke oven working machines such as coke guide cars and fire extinguishing trucks at predetermined positions and with a predetermined stopping accuracy for the furnace to be operated.

``Prior Art'' In order to operate a coke oven working machine reliably, it is important to stop the working machine at a predetermined oven number and within a predetermined accuracy with respect to the center of the oven. The detection method known as the furnace core detection device required for this purpose is to attach a touch roller directly connected to an encoder that emits an electric signal proportional to the number of rotations to the coke oven working machine and move it on the running rail. There is a method of calculating the furnace number and furnace core from an electric signal proportional to the traveling distance emitted by an encoder, but this method was prone to errors due to wear and slippage of the rolling wheels.
No. 180582). Another method is to attach a sign (target) that displays the furnace number and furnace core to the coke oven bank, and install an image detector that optically reads the furnace number and furnace core on the coke oven working machine. There is a method for detecting the furnace number and furnace core, but if the sign or image detector lens is contaminated with dust, the furnace number or furnace core cannot be detected accurately (Special Publication No. 55-44118 ) Another method is to install a transmitting element (magnetic element) of a magnetic proximity switch on the coke oven working machine, and arrange a receiving element (contact element) of the magnetic proximity switch for each oven in the corresponding coke oven group. There is a method of concentrating the output signals in the control room and detecting the running position of the coke oven working machines, but this method has the drawback that it requires a large number of electrical wiring for each oven, which increases the cost (Japanese Patent Laid-Open No. 58 -180582).

``Object of the Invention'' The present invention provides an oven number and oven core detection device for a coke oven operating machine that solves the above-mentioned problems.

"Structure of the Invention" The present invention is a coke oven working machine that travels along a coke oven, and a reading device for detecting the furnace number and furnace core signal is installed on the working machine side, and the reading device is installed on the working machine side to detect the furnace number and the furnace core signal, and the reading device is installed on the working machine side and corresponds to the traveling position of the working machine. The information holding body stores the furnace number and furnace core information, and is stored in the information holding body by the reading device when the working machine is traveling. The present invention is comprised of a furnace number detection device for a coke oven working machine, which is characterized by reading and calculating information on a coke oven, and outputting a furnace number and a furnace core signal.

``Example'' In FIG. 1, numeral 1 denotes a coke oven group, which is composed of several hundred furnaces 2. The coke oven working machine 6 is arranged on a rail 7 laid in a direction parallel to the coke oven bank 1. The information holding body 3 is attached to the oven side perpendicular to the traveling direction (direction of arrow a) of the coke oven working machine 6 at a position where the center position of the oven can be displayed. The number of information holding bodies 3 is the same as the number of coke ovens 2, which are several hundred pieces. Further, the coke oven working machine 6 is provided with a reading device M5 which is arranged in an area corresponding to the information holding body 3 while the machine is running. In Fig. 2, the information holding body 3 is composed of a data storage section 8, a data transmitting section 9, and a battery 10.In the data storage section 8, the number 1 information of the coke oven attached to the coke oven is encoded and stored. The first information is radiated from the data transmitter to the outside as a medium 4 such as a magnetic field and electromagnetic waves, and core information (FIG. 3) is transmitted based on the radiation intensity.

On the other hand, the reading device 5 installed in the coke oven working machine 6 is composed of a reading sensor 11, a controller 12, a power supply section 13,
When the coke oven working machine 6 travels and comes to a position corresponding to the information holding body 3, the reading sensor 11 receives the magnetic field, electromagnetic waves, etc. radiated from the information holding body 3, and the read signal is sent to the controller 12. It is calculated and outputs the first signal 14. That is, the reading device 5 can reliably detect the furnace number without contacting the information holding body 3. In addition, the strength of the magnetic field and electromagnetic waves radiated from the information carrier 3 is strong at the center and weakens as you move away from the center, thereby obtaining core information (Figure 3).
The position of the core of the coke oven working machine can be detected by reading this and measuring its intensity with the sensors 1, 1.

That is, if the distance error in the running direction between the coke oven working machine 6 and the furnace core is measured and is within a predetermined positional accuracy, the furnace core signal v1 is determined.
5 can be output. The information stored in the information holding body 3 includes not only the furnace number and the above-mentioned furnace core data, but also other information can be added.0Although the power source of the information holding body 3 was described as a battery, there is a magnetic field on the reader 5 side. By adding a power supply device according to the above, the battery on the information holding body side can be omitted.

Although the information transmission media has been described in terms of magnetic fields or electromagnetic waves, an optical system that combines a light emitting element and a light receiving element is also possible. Installation adjustment is easy because the separation distance between the two is large, and the information holding body has the functions of both the furnace number and furnace core information, and no electrical wiring is required, so installation is easy even when multiple units are used. Since it is possible to accurately detect the furnace number and furnace core of a coke oven working machine, it has the effect of promoting labor saving and unmanned operation of the machine.
