no. 1 Embodiment approach
[0055] First, a first embodiment of the present invention will be described. figure 1 It is a schematic configuration diagram of the blanking system related to the first embodiment. Such as figure 1 As shown, the unloading system of the first embodiment unloads the product steel plate 1a from the uncut steel plate 1 after rolling (hereinafter, simply referred to as "steel plate 1") placed on a workbench not shown. The material system is composed of camera device 100, laser irradiation device 200, rail 300, gas cutting device 400 (mobile cutting device) and management device 500. In addition, in figure 1 The illustration of the rail 300 and the gas cutting device 400 is omitted in FIG. About the use of track 300 and gas cutting device 400 figure 2 to be described later.
[0056] Above the workbench, an imaging device 100 for imaging the steel plate 1 is arranged. The steel plate 1 can be photographed by the imaging device 100 and the outline 1b of the steel plate 1 can b...
no. 2 Embodiment approach
[0091] As mentioned above, in 1st Embodiment, the gas cutting apparatus 400 advances along the rail 300, and performs gas cutting. On the other hand, in this second embodiment, the rail 300 is not provided, and the gas cutting device 700 runs on the steel plate 1 along the cutting line 2 to perform gas cutting along the cutting line 2 .
[0092] Figure 7 It is a plan view of the blanking system of this 2nd Embodiment. Such as Figure 7 As shown, the gas cutting device 700 includes a main body 702 , a torch 402 for gas cutting, and a laser detector 403 .
[0093] The main body 702 includes wheels 701 . The wheel 701 rotates about its central axis CL, thereby moving the gas cutting device 700 . In addition, the traveling direction of the gas cutting device 700 can be changed by changing the orientation of the wheels 701 .
[0094] When gas cutting is performed, the gas cutting device 700 is advanced. At this time, the gas cutting device 700 performs gas cutting while chan...

Abstract
The blanking system of the steel plate of the present invention does not require equipment investment, and realizes the rationalization and rapidity of the blanking operation of blanking the product steel plate from the steel plate after rolling. The blanking system of the steel plate is equipped with: a laser irradiation device ( 200), irradiating laser light on the surface of the steel plate (1) to draw a cutting line (2) representing the shape of the product steel plate; The cutter (402) and the main body (405) traveling on the above-mentioned steel plate; the above-mentioned mobile cutting device (400) detects the above-mentioned cutting line (2) through the above-mentioned laser detector (403), so as to follow the above-mentioned cutting line (2 ) to implement cutting.
Description
technical field [0001] The present invention relates to a steel plate blanking system and method suitable for blanking a product steel plate from a rolled steel plate. [0002] This application claims priority based on Patent Application No. 2012-276008 for which it applied in Japan on December 18, 2012, and uses the content here. Background technique [0003] Conventionally, when blanking a product steel plate from a rolled steel plate, an operator draws a plotted line on the surface of the rolled steel plate, and performs gas cutting along the plotted line. In order to perform gas cutting along the plotted line, a rail is placed on the steel plate after rolling, and a gas cutting device fixed with a gas cutting torch that blows out a gas flame travels along the rail. In such a blanking method, since the rail is placed on the steel plate using a movable cutting device and the cutting is performed, there is an advantage that the space for the blanking work is not limited. ...
