2. Description of the Related Art For example, as an apparatus for processing main materials such as box girders and steel girders, which are the main girders of steel bridges, a steel plate is carried along a longitudinal direction on a processing line for conveying the steel plate. NC cutting machine from the good side, a long plate cutting machine that cuts both edges in the longitudinal direction of the steel plate while following the writing line with a copying jig, a longitudinal cutting machine with a crater, a width cutting machine, a drilling plate handling machine, a drilling machine ， Used seed plate handling machine ，
BACKGROUND ART A steel plate processing apparatus in which a primer-separator and the like are sequentially arranged is generally known. (For example, JP-A-60-1311
In the above apparatus, the steel sheet to be conveyed on the processing line is simultaneously guided and conveyed along the copying jig, and the left and right writing line portions are simultaneously cut by the large plate cutting crater of the longitudinal cutting machine. During this cutting, the left and right edges of the steel sheet are elongated and twisted waste material is generated due to heat insulation. If this waste material is not processed during cutting, it may come into contact with the copying jig or the large plate cutting crater and damage them, or the crater may come off the scribing line due to shock of collision. For this reason, conventionally, the worker manually cuts the waste material to an appropriate length, but there is a problem that the cutting processing of the waste material that occurs continuously requires at least two workers.

[0003] As a means to solve such problems,
A frame plate as shown in Japanese Kokai No. 56-22315
A residual material cutting device for a corner has been proposed. This equipment

It was made to let you. However, this device
Torch for cutting residual material generated on both sides of steel plate by
Run the frame planar body on the slide rails
By traveling at the same speed in the opposite direction,
It is designed to maintain a stationary state with respect to the board.
Of course, complicated control means are required, and residual material cutting operation
The order is defined, and the holding time, one action and the next action
A timer or a pulse counter that controls the delay time between
If the structure becomes more complicated, such as requiring such means
There is still a problem.

The object of the present invention is to greatly simplify a device for cutting a waste material generated by cutting a steel plate at a large plate cutting crater with a waste material cutting crater that reciprocates in a direction intersecting with a conveying direction of the steel plate at a constant cycle . And to provide a steel plate processing apparatus capable of saving labor.
