う問題が生じる。 However, in conventional mechanical shearing length adjustable shearing machines, the second transport roll that conveys the steel plate to the shearing machine and the shearing machine that shears the steel plate are generally driven by one drive device, and the shearing length can be changed. In this case, the shear length must be changed by changing gears in the drive device and the speed ratio of the continuously variable transmission, and the shear length cannot be changed to a desired length during operation, so the shear device must be stopped to change the length. . In a steel plate shearing line equipped with such a shearing machine, if the operation is stopped and the shear length is changed in order to avoid shearing the weld, the production volume will decrease, so normally the shear length should not be changed. It is something that is not done. In this case, if the shearing timing of the shearing machine and the time when the welded part of the steel plate passes directly under the shearing machine are synchronized, the welded part will be sheared by the shearing machine.
This welded part is made of two overlapping steel plates, so it is thicker than other parts of the steel plate, and shearing the welded part will seriously damage the shearing blade of the shearing machine. The problem arises of shortening the life of the shear blade.
本考案は、上記問題点を解消すべく成されたも
ので、溶接部を剪断することなく、連続的に所定
長さで鋼板を剪断する鋼板剪断ラインを提供する
ことを目的とする。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a steel plate shearing line that continuously shears a steel plate to a predetermined length without shearing the welded portion.

剪断直前で１回、所定長さを越える長さまたは所

らし、溶接部が剪断されないようにしている。 The configuration of the present invention is that in the conventional steel sheet shearing line as described above, a shearing machine driving device that drives the shearing machine and a roll driving device that rotates the conveyor roll are provided independently, and the shearing machine and the shearing machine are controlled by a control device. The position of the weld is determined by dividing the length of the steel plate between the welding machine and the shear length, and the shearing timing of the shear is controlled to prevent the shear from shearing the weld. In other words, since the steel plate is continuously sheared to a predetermined length, the value obtained by dividing the steel plate length between the shearing machine and the welding machine by the above-mentioned predetermined length (shearing length) is an integer or a value within a predetermined range. In this case, the weld will be sheared by a shear. Therefore, in the present invention, the shearing timing of the shearing machine is controlled, and the welded part is sheared once to a length exceeding a predetermined length or less than a predetermined length, and the shearing timing is shifted, and the welding part is sheared once just before shearing. This prevents the parts from being sheared.

It is preferable to determine the position of the weld by determining whether the value is within a predetermined range. Furthermore, when shearing the steel plate to avoid shearing of the weld, the shearing timing of the shearing machine is controlled.
