Description

  The present invention relates to a metal plate test piece identification management method and system for identifying and managing a test piece of a metal plate, for example, after cutting and processing a steel plate manufactured in a cold-rolled steel plate production line, It is used when performing the relevant test.

  Conventionally, management of test pieces cut out from steel materials and steel plates manufactured at steelworks is done by marking each test piece with an individual test piece identification number (alphanumeric characters) in advance and testing it. Occasionally, the operator visually checks the specimen identification number written on the machining / test instruction and the specimen identification number marked on the specimen, and then the machining / test conditions written on the machining / test instruction. We were working according to.

  However, the above-described visual collation by hand has a problem that mistakes or oversights occur. In order to solve such problems, as a technology for automating visual verification, the test piece identification number is converted into a bar code, and the bar code is printed on the surface of the test piece with a paint spraying device or the like for processing and testing. A technique for reading by a bar code reader and eliminating errors in manual collation when performing is disclosed (for example, Patent Document 1).

In addition to the technique of printing directly on the surface of the test piece, there is a technique of attaching a barcode label printed with a barcode to the test piece (for example, Patent Document 2).
JP 59-215216 A Japanese Patent Laid-Open No. 7-27675

  However, as in the technique disclosed in Patent Document 1, it is difficult to always maintain a clear contrast between the paint and the surface of the test piece by the method of directly printing the test piece using paint or ink. The accurate detection of was not always possible. As a countermeasure, it is conceivable to apply a white paint on the background before printing the barcode, and then print the barcode. However, this method has a problem that the white paint cannot be applied uniformly when oil is applied to the surface.

  Similarly, even in the technique disclosed in Patent Document 2, if there is oil on the surface of the test piece, the adhesive strength of the bar code label is reduced and cannot be properly applied, and the subsequent process is peeled off. Was left.

  Furthermore, the conventional barcode is a one-dimensional barcode, and the amount of information held is small, and at most, only information for collation can be obtained. Therefore, even if verification can be automated, there is a problem in that subsequent machining conditions and test conditions must be manually read from the machining / test instruction sheet and manually set in the machine, resulting in setting errors there. .

  The present invention has been made to solve the above problems, and provides a metal plate test piece identification management method and system capable of accurately detecting a barcode and performing processing and testing of an accurate test piece. The purpose is to provide.

  The invention according to claim 1 of the present invention is the step of marking a two-dimensional code including information for identifying it, processing condition information, test condition information on a test piece of a metal plate by a marking marking device, Reading the information of the two-dimensional code stamped on the test piece, collating the test piece with the read two-dimensional code information, processing the test piece according to the processing condition information, and the reading And a step of comparing the test piece with the information of the two-dimensional code and testing the test piece according to the test condition information.

  According to a second aspect of the present invention, there is provided a marking apparatus for marking a metal plate test piece with a two-dimensional code including information for identifying it, processing condition information, and test condition information, and the test. A two-dimensional code reading device that reads information on a two-dimensional code stamped on a piece, and a processing device that checks the test piece based on the read two-dimensional code information and processes the test piece according to the processing condition information And a test apparatus for verifying the test piece based on the read two-dimensional code information and testing the test piece according to the test condition information. .

  In the present invention, in addition to the test piece identification information, the processing conditions and test condition information are engraved on the test piece as a two-dimensional barcode with a marking device, and the two-dimensional code is read in the subsequent steps. In addition to the verification, the machining conditions and test conditions are automatically set and input to the machining apparatus and test apparatus, so that accurate machining and testing of the test piece can be performed.

  FIG. 1 is a diagram showing an overall configuration example of a metal plate test piece identification management system according to the present invention. In the figure, 1 is a test material, 2 is a label, 3 is a test piece punching device, 4 is a bar code reader, 5 is a management computer, 6 is a test piece, 7 is a two-dimensional code generating device, and 8 is a marking marking. Device, 9 is a two-dimensional code, 10 is a processing device, 11 is a two-dimensional code reader, 12 is a verification device, and 13 is a test device.

  In order to extract the test piece 6, for example, a steel plate having a length of 0.5 m is cut as the test material 1 from the coil manufactured in the manufacturing line. The cut test material 1 is affixed with a label 2 printed with a one-dimensional barcode having identification information such as a steel plate production number, and a test piece for cutting out the test piece 6 from the test material 1. It is conveyed to the punching device 3. Before or when the test piece punching device 3 is reached, the one-dimensional bar code is read by the bar code reader 4, and the production number of the corresponding steel sheet is output to the management computer 5 and based on the production number. Thus, the corresponding cutting process conditions are read, and the cutting process conditions are set in the test piece punching apparatus 3. Thereby, it is possible to automatically cut until punching.

  In order to prevent mixing of test pieces after cutting in the punching process here, part of the corners of the test pieces are connected with micro joints, and the test pieces are sorted so that they do not mix. It is conveyed to the sorting process to be performed. In the sorting step, it is possible to classify the test pieces without mixing after cutting the micro joints of the test pieces with a micro joint cutter in a predetermined order.

  Thereafter, the sorted test pieces 6 are conveyed to a marking apparatus 8 capable of marking a two-dimensional code, and the two-dimensional code 9 is stamped on the test piece 6. The two-dimensional code generation device 7 generates information about the test piece number, processing conditions, and test conditions as a two-dimensional code, and sends the information to the marking marking device 8. The marking marking device 8 is a known marking device (generally, an air pen, an air pen) that performs marking by marking the surface of a target material with a stylus (needle) attached to the tip following a reciprocating piston. It is preferable to use a so-called stamping machine. Furthermore, there is a device in which there are a plurality of styluses and they are two-dimensionally arranged. Using this device is preferable because high-speed marking is possible and efficient marking is possible.

  FIG. 2 is a diagram illustrating a conceptual example of marking applied to a test piece. The two-dimensional code 9 is for automating a series of processing. However, in the case where a different material is determined by collation to be described later, it is necessary to visually check by hand. In addition to the two-dimensional code, The test piece number (for visual confirmation) 14 that can be visually confirmed is also marked by the above-described marking marking device. Examples of the two-dimensional code include QR code (registered trademark), data matrix (DATA MATRIX registered trademark), PDF417 (registered trademark), and the like. Although any two-dimensional code can be applied, a data matrix is most preferable in order to increase the recognition rate of the reading device in the steel plate test piece.

  Thereafter, the marked test piece 6 is conveyed to a test piece processing step for testing. When the test piece is set in the processing apparatus 10, the two-dimensional code information is read by the two-dimensional code reader 11 installed in the processing apparatus. In the processing apparatus 10, the processing condition data included in the two-dimensional code read through the collation apparatus 12 is automatically set and processed.

  Next, the processed test piece 6 is transported to the test process and set in the test apparatus 13. The test apparatus is also provided with a two-dimensional code reader 11 and reads the two-dimensional code 9. Then, test condition data included in the two-dimensional code read through the collation device 12 is automatically set and a test is performed.

  Finally, the test result data after the test is output to the management computer 5 and is managed together with the test piece number or provided as test result information of the steel sheet delivered to the customer.

  FIG. 3 is a diagram illustrating a processing flow example of a process of marking a two-dimensional code in the two-dimensional code generation apparatus and the marking marking apparatus. The processing will be described with reference to FIG. 3 and FIG.

  First, when the test piece 6 is conveyed to the marking marking device 8, a two-dimensional code marking command is input to the two-dimensional code generation device 7 manually or automatically (step S101). After that, the two-dimensional code generation device 7 inputs information to be marked as the two-dimensional code 9, for example, test piece number, processing condition, and test condition data from the management computer 5 (step S102).

  Then, the two-dimensional code generation device 7 converts and generates the input information into control data for the marking marking device 8 for marking the two-dimensional code 9 and the visual data (step S103).

  The control data is output to the marking device 8, and the two-dimensional code 9 and the test piece number (for visual confirmation) 14 are marked on the test piece 6 using the marking device (step S104).

  Steps S102 to S104 are repeated until marking is completed for all the test pieces to be marked (No in step S105). If marking has been completed for all the test pieces, the marking process ends.

  FIG. 4 is a diagram illustrating a processing flow example of a process of performing a test operation by reading a marked two-dimensional code in a test apparatus, a collation apparatus, and a two-dimensional code reading apparatus. The processing will be described with reference to FIG. 4 and FIG.

  First, the test piece 6 is attached to the test apparatus 13, and a test start instruction is input manually or automatically (step S201). At this time, data equivalent to the two-dimensional code information such as the specimen number is input from the management computer 5 for verification.

  Then, the two-dimensional code reader 11 installed in the test apparatus 13 reads the two-dimensional code 9 (step S202).

  The collation device 12 performs collation processing to check whether the read two-dimensional code information, for example, the test piece number is the same as the information input from the management computer 5. As a result, if the test piece numbers match (step S203 / Yes), the process proceeds to step S204. On the other hand, if they do not match (No at Step S203), the process proceeds to Step S207.

  If the test piece numbers match (step S203 / Yes), in step S202, the collation device inputs the test conditions out of the read two-dimensional code information, and sets the test conditions in the test device ( Step S204). Under the conditions, test measurement is performed (step S205), and test piece measurement data is output from the test apparatus to the management computer 5 (step S206).

  On the other hand, if they do not match in step S203, it means that a different material has been mixed in, so an alarm for notifying the operator of the test apparatus that the test piece is a different material is output. In step S207, the operator is prompted to confirm the test piece. The operator visually confirms the test piece number marked on the test piece, and confirms the test piece number instructed from the management calculation on the operation monitor or the like. Further, information that does not match is output to the management computer 5 (step S208).

  Steps S202 to S208 are repeated until marking is completed for all the test pieces that are the test target (No in step S209). If the test is completed for all the test pieces, the test process is completed.

  Note that the processing flow of the process of performing the processing operation in the processing apparatus 10 can be realized by changing the test apparatus 13 of FIG. 4 to the processing apparatus 10, and thus description thereof is omitted here.
