Description

Distribution and Checking System of Metal Scrap Compressed Material using Image Data And Method Thereof}

The present invention provides the distribution and image data of metal scrap compacts related to the distribution and acquisition of internal and external image data of the metal scrap compressed material from the shipment of the metal scrap compressed material to the final stage of input of the blast furnace of the steel mill, and the identification of abnormality. The inspection system and method using the same.

As is well known, there are many materials such as tongues from various production activities, molds used and disposed of in various production activities, rebars from demolition buildings, scrap cars from consumption activities, and metal waste such as waste gas cans and cans. Metal scrap is sorted, collected and melted to manufacture various steel materials, thereby recycling resources used for steel production, saving energy, and consequently protecting the environment.

To this end, metal scraps made of various shapes and materials are classified according to materials through basic classification, and the compacted metal scraps are formed into shapes and specifications that can be directly loaded into a blast furnace at the steelmaking company.

Such metal scrap compacts should generally have a sum of width, length, and height of not less than 600 mm and not more than 2,100 mm, and have a maximum length of less than 800 mm and a density of not less than 0.15 g / cm ³ .

In order to manufacture such a metal scrap compacted material, a metal scrap such as steel scrap collected by various paths or a non-ferrous scrap such as aluminum or copper is conventionally classified, and these sorted metal scraps are put into a compression apparatus and compressed to meet the selected specifications. It was molded into a hexahedron to form an iron scrap compact.

These metal scrap compacts must be made of pure metal, of course, but some metal scrap compact manufacturers are contaminated and damaged by the blast furnace molten steel in which steel scrap is provided as the metal scrap is increased by mixing impurities. There was a problem.

As a result, the inspector gets on the vehicle loaded with the metal scraps and uses the metal scrap compressed material after visual inspection every day, so it takes a lot of time and effort to inspect the metal scrap compressed material. Since it is a compression of several metals, the sharp metal protrudes in various directions even after compression, so the process of inspecting it on a loading vehicle is very dangerous. Since it is a heavy weight that cannot be handled by manpower, it is impossible to observe each side of the compressed product evenly, so it is difficult to guarantee the reliability of the inspection.In case of problems, it is difficult to verify the responsible materials. If its cause and responsibilities are impossible to identify There is a problem.

Therefore, a precise inspection to check the inside by shocking or decomposing the metal scrap compressed material which is received into the steelworks irregularly is also performed, but it is time and costly and cannot be carried out with sufficient frequency. Accordingly, metal scrap compacts manufacturers are still manufacturing metal scrap compacts by incorporating impurities.

In addition, in the past, a number of unjust cases have occurred in the transportation process from the manufacture of the metal scrap compacted material to just before it is introduced into the steelworks furnace.

That is, the weight difference between the total weight of the vehicle loaded with metal scrap and the tolerance weight after unloading in the steelworks weighbridge is calculated so that the weight and number of the metal scrap compressed materials can be determined. There is an irregularity that manipulates the results of weighing the vehicle through public offering.

In addition, part of the loaded metal scrap is removed, and water is added to the weight of the removed metal scrap compressed material through the weighbridge. Unclean cases are frequently occurring.

An object of the present invention to solve this problem is to take the image of the moment the metal scrap is loaded in order to carry out the compression process before shipment of the metal scrap compressed material to secure the image data, and to identify the compression means to the compressed material after performing the compression process In addition, the vehicle registration number, tolerance weight, loading gross weight, departure year, month, day, hour and minute data of the vehicle loaded with a plurality of compressed materials are stored and provided to the steelworks server. The present invention provides an inspection system and a method using the distribution and image data of metal scrap compressed material that can be used for receipt and inspection on the side.

In order to achieve the above object, the present invention provides a camera for securing image data by performing photographing while a metal scrap is loaded in a compression chamber of a compression product manufacturer, and an identification for attaching identification means to the corresponding compressed product. Means attachment device, and a microprocessor equipped with a weighbridge to input the tolerance weight secured at the time of registration of the vehicle, the total weight of the vehicle detected by the load cell after loading is completed, the vehicle number, and the departure time of the weighbridge; A memory for storing data and data obtainable from the weighbridge;

An infrared transmitter for detecting the start of operation of the apparatus for attaching the identification means operated by the microprocessor when the compressed article reaches a predetermined position, an infrared receiver, and a driver for driving them;

A multiplexer for sequentially outputting image data output from one or more cameras, a connector for transferring the generated compressed data to a terminal,

We propose an inspection system using data and a method thereof.

In this way, the present invention is to produce a compressed product in the compressed material manufacturer to carry the image data of the metal scrap is put into the compression chamber, the ID data of the compressed material in which the metal scrap is compressed, and various data that can be obtained from the weighbridge By serving to the submission server before reaching

If necessary, the inspector can quickly and accurately read the metal scrap status of the compressed product in the working place where the display is installed and determine the abnormality before the vehicle arrives at the steel mill.

The defective compacts that have a problem can be secured by selecting ID in advance, and the compressed materials made of good metal scrap can be sorted and put into the blast furnace immediately upon arrival of the vehicle, thereby improving work efficiency. It becomes possible.

In addition, in the case of inspection after pre-injection, it is possible to identify the responsible material by obtaining image data from the memory where the metal scraps manufactured the compressed material are stored in case of accidents caused by the introduction of foreign substances, so that the compressed material of good quality can be distributed. It will be able to induce.

In addition, in the present invention, the compressed material may be input to the blast furnace while reading the ID of the compressed product while sequentially loading the compressed product into the blast furnace, and reading the image data in real time.

In addition, in the present invention, when the loaded truck arrives at the steel mill starting from the compressed material manufacturer, the vehicle weighs the vehicle at the weighbridge and monitors whether there is a change in the gross weight of the truck. The absence of water is identified, which has a useful effect of preventing unintended accidents such as thefts that occur during distribution.

In particular, the present invention is not to confirm the abnormality of the metal scrap as a raw material by impacting the bulky and heavy compacts or by using a welding machine to inspect the compressed material, the compression of the metal scrap as a raw material in a compression facility Before the image data is obtained and provided to the steel mill side, there is a useful effect that it is possible to fundamentally and clearly verify the raw material abnormalities of the compressed material.

In addition, the present invention, as shown in FIG. 2, one or more cameras 40 are installed around the compression chamber of the compression facility used by the compression manufacturer to produce the compression product 20, and the image data obtained therefrom is As shown in the circuit diagram shown in FIG. 4, the memory 50 is stored in the memory 50 under the control of the microprocessor 70 via the multiplexer 60. In addition, the shipping position should be provided with equipment as shown in FIG. 3.

That is, in the present invention, the identification means such as a bar code label or an RFID tag having an adhesive layer is attached to the compressed product 20 to give an ID to the compressed product 20. The identification means attaching device of FIG. It is possible to attach automatically by 130.

In addition, the identification means attaching device 130 illustrated in FIG. 3 of the present invention has a rod for attaching the identification means as shown by a dashed line, protrudes from the main body, and adheres the identification means at its tip while contacting the compressed material 20. It can be carried out in an in-situ form.

Also, in order to move the compressed material 20 to the identification means attaching position, as shown in FIG. 10 may be used, and the compressed material 20 may be placed on a pedestal at a fixed position with a fork lane, and may be loaded on a vehicle after the identification means is attached.

In addition, in the present invention, before the metal scrap is charged into the compression chamber and compressed, the image data obtained from the plurality of cameras 40 may be sequentially stored at the designated address of the memory 50, and the above-described identification means attacher ( It is a matter of course that the ID data of the identification means attached by the 130) is stored together with the image data of the metal scrap prior to manufacturing the compressed material 20.

In addition, the present invention is equipped with a weighbridge, the vehicle registration number secured at the time of registration of the vehicle, the tolerance weight and the signal detected by the load cell after loading is completed, the total weight data of the vehicle obtained through the A / D converter 100, weighing platform Departure year, month, day, time data is input to the microprocessor 70 through the LAN,

The microprocessor 70 stores the data output from the weighing station together with the ID data and the image data at an address in a specified range of memory.

The overall configuration of the compressed data generation system according to the present invention is shown in FIG. 4, which includes an identification device attachment device 130, a weighbridge reader 90, one or more cameras 40 installed on the compression chamber side, and Infrared transmitter 72, infrared receiver 73, and microprocessor 70 to detect the approach to the identification means attachment device 130 position of the compressed material 20 is connected to the infrared transmitter 72, infrared The first driver 71 for driving the receiver 73, and the connector 120 for connecting the terminal 110 and the microprocessor 70.

In addition, as shown in FIG. 1, the terminal 110 transmits the compressed data transmitted by the microprocessor 70 to the steelworks server 200 through a communication network such as the Internet or an intranet.

The inspection system is provided with an identification means reader and a display 201 for inspectors installed adjacent to the weighing platform and the blast furnace input conveyor 10 connected to the steelworks server 200 and the LAN.

Referring to the flow diagram shown in Figure 5 the operation of the present invention as described above is as follows.

The present invention first outputs the image data obtained immediately before the metal scrap compression from the at least one camera 40 installed on the compression chamber side of the compression facility for compressing the metal scrap to a high pressure, the image data is a microprocessor 70 By the multiplexer 60 controlled by the in order to store in the memory 50.

Here, the metal scrap compaction equipment is a large-scale automation equipment, and the opening and closing doors of the compression chamber opening and closing of the metal scrap compaction equipment are all controlled automatically. After the metal doors are closed and the closing door is closed, the compression is completed. Since the compression chamber is open because it can not be arbitrarily opened until the completion of the introduction of scraps of metal, the compression chamber is closed after the compression chamber is closed, so that no more metal scraps can be added as well as impurities, and the compression chamber is opened. Continuous image data of the entire process of closing the compression chamber can confirm whether impurities are added.

Subsequently, in the compression chamber of the compression facility, the photographed metal scrap is compressed to form a metal scrap compact 20 (hereinafter referred to as a 'compressed article'), which is dropped during the production process or lifted by a forklift as shown in FIG. 3. It is put on the conveyor 10 together. As such, the compressed product 20 mounted on the conveyor 10 is moved downward and rightward in FIG. 2 by the conveyor 10 driven by the microprocessor 70, and at this time, by the microprocessor 70. A compressed object conveyor step is performed in which the states of the infrared transmitter and the infrared receiver 72, 73 which are transmitting and receiving infrared rays by the output of the first driver 71 are reversed to block the transmission and reception of infrared rays. This condition is detected by the microprocessor 70, the microprocessor 70 is carried out a conveyor operation stop step of stopping the drive of the conveyor belt drive motor.

Accordingly, the compressed product 20 is stopped at a predetermined position, and the microprocessor 70 drives the identification means attacher 130 to attach the identification means, and the identification means attacher 130 identifies the ID of the corresponding identification means. Attached to the compressed material identification means to be transmitted to the microprocessor 70 and performs the ID storage step.

In this way, the present invention obtains both the ID of the compressed material 20 and the image data which can grasp the property of the metal scrap inserted into the compression chamber before the compression process is performed and input it to a specific address of the memory 50.

Subsequently, the microprocessor 70 of the present invention operates the conveyor belt driving motor 100 in the opposite direction as before, so that the compressed product 20 is moved to the left and the upper side of FIG. To stop.

Subsequently, the driver of the forklift lifts the compressed product 20 on the conveyor 10 and loads it in the loading box of the truck.

If this process is repeated, a sufficient number of compressed materials 20 are loaded in one truck, and in this state, IDs and compressed materials of the plurality of compressed materials 20 are stored in the memory 50 of the compressed data generation system. (20) The metal scrap image data which is the raw material before manufacture is in the state stored in the address of a specific range.

After doing this, the driver of the truck loaded with the compressed material 20 drives the truck and enters the weighbridge, and is attached to the windshield glass of the truck by the RFID reader 90 installed on the weighbridge. The gross weight calculated by the microprocessor 70 by reading the data of the RFID card and outputting the vehicle registration number of the vehicle, the pre-registered tolerance weight data, and the signal detected by the load cell of the weighbridge; The stepping vehicle vehicle data memory storage step of storing the weighing vehicle departure time data at an address connected to the address of the memory 50 in which the corresponding compressed product ID and the metal scrap image data were previously recorded is performed.

The driver then drives the truck to arrive at the steel mill, while the microprocessor 70 of the compact data generation system is adapted from individual IDs, individual scrap image data, and weighbridges of all the compacts 20 stored in the memory 50. Data such as vehicle registration number, tolerance weight, loading gross weight, weighing station departure time data of the provided transport vehicle will be transmitted to the terminal 110,

The terminal 110 transmits such data to the terminal steelworks server 200 through a communication network such as the Internet or an intranet.

Accordingly, before the truck driving by the driver reaches the steel mill, the server 200 on the steel mill side receives the corresponding data and stores the data in the memory.

In this state, the inspector of the steel mill side may use the metal scrap image data for each ID stored in the steel mill server 200 to look at the metal scrap images for each ID through the display 201. In the case where it is read that there is an abnormal substance in the raw metal scrap, the defect determination data is immediately added to the compressed data of the corresponding ID stored in the memory, and the updated ID compressed product defect determination data is further added.

In addition, when there is no abnormality as a result of the inspection of the metal scrap image of the compressed product through the display 201, the good judgment data is immediately added to the compressed data of the corresponding ID stored in the memory, and the updated ID compressed data is further updated. To perform the steps.

This inspection process can be completed before the vehicle loaded with a number of compressed materials 20 enters the weighbridge as shown above,

In this way, the scrap image of each ID is read, and the ID is classified according to the quantity and part of the compressed product to update the data.

When the vehicle arrives in such a state, the steel mill weighbridge recognizes the vehicle number and notifies the steel mill server through the LAN.

Therefore, the steelworks server determines whether or not the vehicle number corresponds to the vehicle number previously stored in the memory, and if it matches, it is regarded as an authenticated vehicle, and the vehicle that fails authentication has a request for unloading.

In addition, the total weight of the loading vehicle is calculated based on the signal output from the load cell of the weighbridge.

On the basis of this, when the current total weight of the loaded vehicle is out of the tolerance range compared with the stored total weight already transmitted, it is notified that the vehicle is an abnormality.

For example, if a difference of more than 30 kg by more than 30% of the weight of one compressed product 20 is considered to be outside the allowable range, the compressed material manufacturer will be notified of the total gross weight or more. If so, it is considered to be within tolerance, and the subsequent process is carried out. In this process, when it is in the tolerance range that enters the weighbridge, the compressed material loaded on the vehicle is moved on the conveyor using a fork lane. In this process, if the ID of the compressed product 20 is detected by the identification means reader 202 installed on the conveyor side, it is transmitted to the steelworks server 200 through a LAN, and the steelworks server 200 stores data already stored in the memory. It is determined whether or not the ID has been judged good or by the ID determined bad.

As a result, if the ID is judged to be defective, the compressed material is moved to the designated place by the steel mill by the conveyor.

In the case of the ID having been judged to be good, the compressed material is introduced into the blast furnace by the conveyor.

After doing this, when there is no compressed material conveyed by the conveyor for a predetermined time, the work is considered to be finished.

In this process, the present invention immediately transmits the compressed material data to the steelworks server when the vehicle loaded with the compressed material departs to the steel mill side, finishes the inspection in advance, and gets off after the arrival of the vehicle to filter out the compressed product of the defective ID. Since only the compressed material of ID which has been judged as good can be put into the blast furnace, very quick and accurate inspection can be performed.

In addition, the present invention can also be implemented in the form shown in FIG.

That is, in the present invention, unlike the method of FIG. 5 described above, the compressed data and the vehicle data are transmitted to the steelworks server through a communication network.

Image of the metal scrap used to manufacture the compressed material according to the ID of the unloaded compact, if the vehicle registration number certification and the loading gross weight are within tolerance after the vehicle leaving the compact manufacturer has reached the weighbridge of the steelworks. By repeating the process of reading data through the display 201, only good compressed material can be introduced into the blast furnace of the steel mill.

The present invention is described in more detail with reference to FIG. 6 as follows. In this embodiment, in the same process as in the embodiment of FIG. 5, the compressed material manufacturer and the vehicle-related data are transmitted from the terminal to the steelworks server through the communication network and then transported to the vehicle. After the input, it is determined whether the company is the subject of inspection, and when it is not the target of first-in, the ID of the compressed product which is loaded by the forklift and loaded on the conveyor is sequentially detected. In this process, since the ID of the compressed product is detected by the identification means reader 202 and transmitted to the steelworks server through the LAN, the steelworks server 200 stores the compressed product 20 previously stored in the memory through the display 201. The abnormality of the metal scrap which is a raw material of) is judged.

If it is determined that the foreign material is contained in the metal scrap of the compressed material 20 through this process, the defect data is added to the compressed data of the inspected ID stored in the memory to update the data, and the compressed material is designated. In this case, the conveyor will automatically move to the designated place.

In addition, when it is determined that there is no abnormality in the metal scrap of the compact 20, the compact 20 is put into the blast furnace by the conveyor, and data indicating the completion of the blast furnace addition is added to the data of the compact. To update the compressed data.

In addition, in the above-described process, the compressed material which has been unloaded from the vehicle of the inspection target after the first input is continuously injected into the blast furnace through the conveyor at the same time as the unloading, and as shown in FIG. By reading the extrudate ID, and transmits it to the steelworks server through the LAN, the steelworks server updates and stores the data with the contents indicating that the ID data is put into the blast furnace in the memory,

Subsequently, the conveyor is continuously operated to inject the compressed material into the blast furnace.

On the other hand, if a problem occurs due to the foreign matter introduced into the blast furnace due to the amount of water introduced in this way, by checking the display 201 through the display 201, the metal scrap image data corresponding to the input of the compressed material to check whether or not mixed with It will be possible to identify the responsibilities.

In this way, all the compression loaded on the truck is processed so that there is no loading of the compressed material 20 for inputting into the blast furnace by a fork lane for a predetermined time, so in this case, the inspection operation is finished.

In addition, as described above, the pre-inspection subject to be pre-injected may be applicable to the case of pre-injection into the blast furnace for the rapid process in the case of a compressed product manufacturer that has a track record of providing a compressed product 20 of stable quality. to be.

In addition, in the present invention, a bar code may be used as the identification means, and in this embodiment, the identification means attaching device 130 may operate a barcode in the form of an adhesive sticker having an adhesive layer on the compressed material 20 while the identification means attaching device 130 is operated. The identification means reader 202 connected to the steelworks server 200 and the LAN may use a barcode scanner.

In addition, in the present invention, an RFID method may be employed as an identification means, and in such an embodiment, an adhesive layer is formed on the RFID tag to be attached to the compressed material 20 by the identification means attacher 130 and the steelworks server 200. The identification means reader 202 connected to the LAN may use an RFID reader.

In addition, the present invention is provided with a system for identifying the vehicle registration number in the weighbridge and connected to the terminal 110 or the steel mill server 200 in a LAN, the truck departing from the weighbridge of the compact manufacturer arrives at the steel mill side weighbridge Although authentication is performed using the vehicle registration number, authentication may be performed by manually inputting the vehicle registration number as necessary.
