できるものである。2. Description of the Related Art For example, when a rolled section steel such as an H-section steel or an I-section steel is manufactured, a defective shape called a tongue is generated at a leading end or a rear end of the section steel. In an intermediate process or a final process, the steel is cut and removed as an unnecessary part to manufacture a shaped steel product. In such a cutting operation, it is important to accurately cut the tongue position in terms of improving the biting property in the next process mill, product accuracy and quality, and product yield. No. 56-3133. The content of this technology is to move the position of the section steel conveyed from the predetermined cutting position on the pass line to the temporary cutting position on the downstream side by the roller conveying means including a roller table, and to move and move the position of the parent and child carriages and the stopper. It is a method for setting a cutting position in a cutting equipment for a shaped steel that is moved and positioned to a predetermined cutting position by a positioning means, and cuts the positioned shaped steel with upper and lower cutting blades, and the cutting object is cut. By stopping the temporary cutting position of the section steel before the moving / positioning means, it is possible to prevent the section steel from colliding with the moving / positioning means, thereby damaging the moving / positioning means and causing the section steel to collide or rebound. Can be prevented from becoming inaccurate.

をその目的とする。However, the prior art disclosed in Japanese Patent Application Laid-Open No. 56-3133 has the following problems. That is, in a rolled section steel production line, section steels are generally rolled and manufactured continuously, and various process times in each step are greatly reflected in production costs, so that the time required in each step is reduced. Is desired. Here, as a method of shortening the setting time of the cutting position in the section cutting step, if the moving speed to the predetermined cutting position is too fast, the type of the section steel to be cut is
The size is large and the weight is greatly different, so the inertia force during movement is also greatly different. Therefore, depending on the type, the predetermined cutting position is over-learned by the inertial force, and as a result, the time required for the positioning becomes longer. Therefore, in the current actual operation, the section steel is moved slowly and positioned. As a result, much time is required for positioning, and there is a limit in reducing the production cost. Further, when stopping the material at the temporary cutting position, it is necessary to stop the material in the movable range of the moving / positioning means without colliding with the moving / positioning means. Naturally, the movable range is limited in terms of equipment costs, so that good precision is required for the temporary cutting position of the material. In view of the above-mentioned problems of the prior art, an object of the present invention is to provide a method for setting a cutting position in a section steel cutting facility, in which the positioning can be performed accurately and quickly, thereby improving productivity.

Next, the operation of the device will be described. FIG. 3 is an explanatory diagram of the operation procedure for the tongue on the right side. The operation procedure of the device of the present invention is as follows. (1) In FIG. 3 (a), the tongue on the right side of the section steel 1 transported by the roller transport means 2, that is, the section steel 1 transported from left to right as indicated by an arrow A in FIG. 3 (a). When the tip 1a is detected by the first tip position detector 3, a detection signal is input to the control device 8 (FIG. 1), and the control device 8 decelerates the motor of the roller 2a. Next, shaped steel 1
Is detected by the second front end position detector 4, the motor M is stopped after the predetermined distance is conveyed by the PLG count, the conveyance of the shaped steel 1 is stopped, and coarse positioning is performed. . The rough positioning is set so that the cutting position of the section steel 1 is located before the cutting position 15 of the cutting machine (right side in FIG. 3). (2) As shown in FIG. 3B, the retracted swing arm 10 is rotated downward, and the pressing member 12 is positioned in front of the tip 1a of the shaped steel 1. (3) As shown in FIG. 3 (c), the pressing member 12 is advanced by the hydraulic cylinder 13, and the shaped steel 1 is pressed and positioned. When the section steel 1 is pressed by the pressing member 12, the section steel 1 is pressed against the pressing member 12 by rotating the roller 2 a of the roller conveying means 2 toward the pressing member 12, and the section steel 1 flows on the roller by the pressing. Can be prevented. (4) As shown in FIG. 3 (d), it is controlled that the cutting position of the section 1 has reached the cutting position 15 of the saw based on the moving distance detected by the detecting means 14 for detecting the moving distance of the tip of the pressing member. When it is determined by the device 8 (FIG. 1), the rotation of the roller 2a and the advance of the pressing member 12 are stopped.
Cut the tongue on the right side of the. (5) As shown in FIG. 3 (e), when the cutting of the right tongue is completed, the swing arm 10 is rotated upward to retract the pressing member 12, and then the section steel 1 is roll-transported. 2
To be transported. The cutting position of the left tongue is set and cut by the same operation as that of the right tongue, as shown in FIG. That is, in FIG. 4, when the tip of the left tongue of the section steel conveyed by the roller conveying means 2 is detected by the first tip position detector, the motor of the roller is decelerated. Subsequently, when the tip of the shaped steel is detected by the second tip position detector, the motor is stopped after the predetermined distance is conveyed by the PLG count, and coarse positioning is performed.
The rough positioning is set so that the cutting position of the section steel is located after the cutting position of the saw (left side in FIG. 4). Next, after the retracted pressing member 12 is positioned in front of the tip of the section steel, the pressing member is advanced, and the section steel is pressed and positioned. When pressing the shaped steel with the pressing member, the shaped steel is pressed against the pressing member by rotating the roller toward the pressing member,
Prevents running on roller tables. When it is determined by the control device that the cutting position of the shaped steel has come to the cutting position of the saw based on the moving distance detected by the detecting unit that detects the moving distance of the tip of the pressing member, the rotation of the roller and the advance of the pressing member are performed. After stopping, cut the tongs on the left side of the section steel with a saw. When the cutting of the tongue on the left side is completed, the swing arm is rotated upward to retract the pressing member upward, and then the section steel is transported by the roll transporting means.

い。According to the present invention, the section steel conveyed to the temporary cutting position is moved in the direction opposite to the conveying direction by the moving / positioning means while rotating the rollers of the roller conveying means in the conveying direction. In order to set the predetermined cutting position, even if the moving speed of the pressing member is increased, the braking force from the roller is applied to the lower surface of the moving shaped steel during this time, so that the shaped steel is moved at a high speed. There is no over-learning from the predetermined cutting position due to the inertia force generated at that time. Thereby, the setting operation of the cutting position can be performed accurately and quickly, and the productivity is improved. Also, since the rollers are rotated in the transport direction at a very low speed, the moving / positioning means is moved to the predetermined cutting position in the reverse direction even if the material stop does not exceed the cutting position by rough positioning (FIG. 3). During the setting, the material is conveyed by the roller, so that the rough positioning failure of the material can be relieved. When the section steel to be cut is transported to the temporary cutting position, the moving / positioning means is retracted from the pass line.
If the section steel is transported to the coarse positioning zone, even if the zone is over-learned, the section steel does not collide with the moving / positioning means and the means is not damaged.
