The present invention improves productivity by computerizing production management through the automatic management of the steel plate input management and steel information in real time in the pretreatment process that performs non-contact automatic marking on the steel plate for wire rod or manual marking in shipyards handling large steel sheets. The present invention relates to an automatic marking system for steel information for wire rods.

Currently, when marking letters or numbers on steel materials, workers can stamp work information by hand or mark it by hand, and some companies use manual marking robots, server communication via modems, and bar codes. Automatic marking and production control computerization system using ID input module and separate steel standard detection system has been established, but automatic marking cannot be performed in response to steel plates entering irregular positions on conveyor width. Since it is necessary to align the position within the section, it is inconvenient to follow work constraints when mounting steel on the conveyor by crane. In case of small steel (1M), if there is much information to be marked, marking processing is difficult, and accurate steel transfer to subsequent process Corresponds to the hazardous location information or the transportation destination for the steel It is impossible to mark the information or the marking character is too small to be practical, and it is inconvenient to introduce and manage a separate bar code management system for processing the order information of the imported steel. The automatic marking of steel information such as steel is difficult, and due to problems in the data processing method between the steel standard detection system and the actual steel information, such as the failure of the practical use, only the partial function is used.

E. ID (Identification Number) input module 201,

The module unit is composed of a portable ID input unit 203 and an ID input and correction query unit 202 and has the following important functions.

1) Portable ID input unit 203-It consists of a wireless base station and a portable radio terminal connected to the file server (S) through a modem as a hardware, and to the crane for the material management of the steel material brought into the preprocessor. When the operator keyes the ID number (unique identification number) of the steel plate mounted on the conveyor into the portable wireless terminal 203, the main information about the steel is inquired from the file server through the base station and the screen of the portable wireless terminal 203 is displayed. On the basis of this information, the operator judges the authenticity of the steel and decides whether or not to import the steel, and inputs the key to allow the import. The order of steel sheet is automatically determined and recorded and managed in the file server through the base station. In order to deliver information on the steel import order, the OCR card is transferred to the next work process (hand marking process). To eliminate the inconvenience that must be passed, and also provide the ability to relatively increase the working efficiency by maximizing the radius of action of the operator to employ a wireless manner.

The marking server frequently checks the steel information to verify the authenticity of the marking information while marking robots for entering steel in real time. It reads from S) and outputs it at the same time as importing the steel plate, and provides the function to search, modify and input the information about the place where the steel sheets waiting to be marked are placed (loading place number) or the next workshop number to which the steel is delivered. .

4 is a flow chart of the present invention consisting of the above-described software module showing the transmission of the steel material for marking and the production management data centering on the file server (S) and the operation state will be described in detail as follows. same.

First, when the operator inputs the ID number (unique identification number) of the steel plate mounted on the conveyor in the ID input module 201 to the portable wireless terminal 203, the main information about the steel is inquired from the file server through the base station and is portable. It is displayed on the screen of the wireless terminal 203 and the operator judges the authenticity of the steel based on this information, determines whether or not to carry in, and inputs a key to allow the import of the steel sheet. S) record management and steel information management control module 111 reads the steel plate information to be marked periodically from the file server (S) and manages by a certain amount and at the same time with the information of the back and forth work steel on the monitor screen for the operator's work confirmation When the steel reaches the sensing carriage 2, the entry detection sensor 4 (4 ') detects this and sends it to the system interlock control module 113. It transmits the arc and the sensing carriage (2) is operated to read the entry position of the steel plate 11 and the width value of the steel to transfer to the robot control module unit 114 and the marking robot (1) operates according to this value to the steel (11) ) Moves the print head T to the entry position, and the signal transmitted to the system interlock control module 113 by the entry detection sensors 4 and 4 'formed on the sensing carriage 2 is a steel material information control module. Also transmitted to (111) and according to this signal, the steel information management module combines the marking information of the corresponding steel of the steel information already read from the file server (S) in the order of entry of the steel sheet marking information and injection control module 112 To be transmitted in real time.

When the steel enters the lower portion of the print head T, another entry sensor 14 detects this and descends the Z axis of the marking robot 1 of the robot control module 114 to approach the print head T on the steel sheet. Let's do it.

At this time, the height sensor 8 of the marking robot 1 operates to control the Z axis of the robot 1 so that the print head continuously maintains a constant distance from the steel sheet, and then moves the robot Y axis at high speed. Give a marking start command to the marking information and injection control module 112 through (113).

When the marking is completed, the robot 1 returns to the home position and enters the working standby state. The marking end signal is transmitted to the system interlock control module unit 113, and the module unit transmits this signal to the steel information management control module 111. Then, the marking work of the steel is completed and real-time production management of the marking steel is performed.

In addition, the steel check and stockyard number management module 204 reads the steel information given the serial number from the file server (S) from time to time and outputs in real time, and if necessary, the number of the stockyard or workshop to which the steel is to be transferred by hand operation. By inputting correction, when marking steel information, these information can be marked simultaneously.

Referring to the effects of the present invention configured and operated as described above in detail.

1. In the shipping and checking process of steel, frequent OCR card transfer and movement between workplaces is unnecessary, and due to the drastic reduction of work orders, distribution of file lists and stock piles is unnecessary. In addition, wireless checking input method is applied during steel checking, so there is almost no work error during delivery of steel entry order information and inspection of steel shipment, and it is possible to immediately grasp the status of steel shipment.

2. In the pretreatment process, it is easy to manage by centralized equipment control, and it can save the extension base for monitoring the pretreatment equipment operation status in the future and can automatically control the primer method by software.

3. In the marking process, remote monitoring of the marking equipment is possible, real-time production control of pretreatment is possible, and the number of management personnel can be greatly reduced.

4. In the trans bay process, it is possible to automatically output the steel identification data, and computerized management of the transbay pile pile loading status and stock status of the steel sheet can maximize productivity efficiency and reduce human and material cost. You can see the effect.
