    Metal sheet cutting device and its cutting method
    The present invention relates to a metal sheet material cutting device and a cutting method thereof, and more particularly, by installing an automatic operation processing device using an encoder and a dip sensor, the size of the metal sheet material (product) having different cutting effective surfaces is the same. The present invention relates to a metal sheet cutting device that can increase productivity by cutting precisely one by one, automatically adjusting the feed rate, and preventing double cutting.
    1 is a schematic diagram schematically showing a cutting device of a shadow mask which is a conventional metal sheet material, and FIG. 2 is an explanatory view showing a cutting process of the shadow mask 10. Referring to this figure, the carrying out roller 20 which carries out the continuous shadow mask 10 of an etching process, and the motor 72 which conveys the shadow mask 10 carried out by this carrying roller 20 are conveyed. The branch detecting portion 30 includes a feed roller 70, a cutting detection sensor for detecting a cutting effective surface 12 between the shadow mask product and the product, and determining a cutting position, and the shadow mask 10 conveyed during cutting. Cutting effective surface of the dip part 40 having a deep bar that accumulates), the upper / lower limit detection parts 52 and 54 that control the transfer of the dip bar due to deflection of the steel plate, and the transfer when descending. It consists of the cutting part 60 which has the cutting blade which cuts (12).
    The cutting method of the conventional shadow mask cutting device configured as described above is as follows.
    3 is a flowchart showing a flow of a cutting process of a conventional metal sheet cutting device. When the continuous shadow mask 10 carried out by the transport roller 20 of FIG. 1 is transported by the transport roller 70, the cutting detection sensor of the cutting detection unit 30 is cut effective surface 12 of FIG. 2. That is, after detecting a non-transmissive part, the cutting blade of the cutting part 60 is operated to cut the metal material by the cut shadow mask 100 is made.
    After the cutting is completed, the iron plate is re-transmitted to repeat the above operation, and if the number of times the dip bar of the dip unit 40 rises, the upper limit detection sensor 52 is activated to stop the iron plate transfer.
    Then, when the dip bar is lowered as the iron plate sag, the lower limit sensor 54 is operated to resume the transfer of the iron plate, and the above operation is repeated.
    By the way, the conventional metal sheet material cutting device and the cutting method having the above structure adopts a method in which the continuous shadow mask 10 is cut by a cutting blade when transferred by the feed roller 70, and cutting When the fixed cutting detection sensor on the sensing unit 30 detects the cutting effective surface 12, the transfer of the shadow mask 10 is stopped and the cutting is performed. As shown in FIG. 2, the width of the cutting effective surface 12 is different. In this case, when the size of the cut shadow mask 100 is changed and is loaded, scratches and bending occur and become a defect.
    In addition, since the cutting is repeated in FIG. 1 and the feeding speed is faster than the discharging speed, deflection of the shadow mask 10 is reduced, the dip bar of the dip part 40 is raised, and the upper limit detection sensor 52 is operated to stop the feeding. At this time, when it is operated simultaneously with the cutting detection sensor of the cutting unit 60, the cutting occurs among them to cut the product, not the effective cutting surface of the product occurs.
    Therefore, an object of the present invention is to adopt an encoder and a dip sensor to cut the metal sheet material having different intervals of the effective surface of the metal material in the same size, to adjust the feed rate automatically and to prevent the double cutting of the cutting process An object of the present invention is to provide a metal sheet cutting device capable of improving efficiency.
    In addition, another object of the present invention is to adopt an encoder and a dip sensor to cut the metal sheet material having different intervals of the effective surface of the metal material in the same size, to adjust the feed rate automatically and to prevent the double cutting cutting process It is to provide a metal sheet material cutting method that can improve the efficiency.
