Abstract

PURPOSE:To improve operating efficiency without hindering the conveyance of a succeeding stock by capturing the connecting part between the rolling stock in continuous type hot rolling during high velocity traveling, cutting the connecting part and removing said part to the outside of the line. CONSTITUTION:The traveling velocity of the rolling stock under continuous travel is detected by a detector 1 and is inputted to a control device 6. The hole position bored preliminarily to the stock S is also detected and is inputted to the sevice 6. The position of the connecting part is operated and tracked by the traveling velocity signal and the hole position check signal in the device 6 and the simultaneous operation signal is outputted to a rolling stock lifter 4, a rolling stock pincher 5 and a set of cutters 3a, 3b. Only part of the belt-like stock S where the connecting part exists is instantaneously cut during traveling on the line and the rolling piece including the connecting part is immediately expelled off the line by the pincher 5. The succeeding rolling stock is conveyed in the coiling direction without receiving any influence at all.

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application The present invention relates to a continuous hot rolling process in which continuous rolling is carried out by joining the rear end of a preceding rolled material and the leading end of a trailing rolled material. The present invention relates to a method and apparatus for detecting and cutting a rolled material joint during rolling and automatically removing it from the running line.

However, in this continuous rolling method, the quality of the joint rolled at the same time is significantly inferior to that of other parts, so it is necessary to remove the part after finishing rolling to produce a finished product. However, since the running speed of the rolled material in continuous hot rolling usually reaches as high as 1'100 m/mir+, it is not easy to detect joints during rolling. To be careful, no high-speed partial cutting means has been developed so far, and crop removal during high-speed rolling has not been possible.

(e) Function The function of the developed method will be explained once with reference to FIG. 1 showing the basic configuration of the present invention. In the method of the present invention, the running speed of the continuously running rolled material S is first measured by the speed accumulator 1.
This is detected by the control device B and inputted to the control device B. Simultaneously with this speed detection, the hole position detector 2 also detects the position of a hole drilled in advance in the rolled material S, and based on this, the connection portion position is predicted and calculated.

As soon as the cutting is completed, the cutting machines 6α and 6 are immediately separated vertically to open a path to the top of the subsequent rolled material S', and the subsequent rolled material S' moves straight on the conveyance line (Fig. D). At this time, the lifting roller 41 is located above the conveyance line, but in anticipation of this situation, a preliminary guide roller 42 is provided below the lifting roller.
- so as to be able to rise and align with the level of the transport line. On the other hand, the cut piece S including the connected part after being cut
" is removed out of the line by the reversal of the pincer arms while being held by the pincer arms 51.52. (Fig. 4) When the pincer arms 51.52 have finished removing the cut pieces, the pincer arms 51.52 again is in the open state, rotates normally, and charges the rolled material from one side, returning to the upper and lower positions of the rolled material conveying line as shown in Figure (E), and the lifting roller 41 also By moving laterally from the side of the rolled material, it returns to its original position under the conveyance line as shown in the figure (CF) and prepares for the next cutting and removal.

(2) A hole position detector that optically detects the position of each hole provided at the upstream position of the rolled material connection part, and a speed detector that detects the running speed of the rolled material, and a hole position detector that detects the position of each hole provided at the upstream position of the rolled material connection part, and a speed detector that detects the running speed of the rolled material, and a Two pairs of high-speed cutting machines are placed in the middle of the two pairs of high-speed cutting machines, which rotate and operate synchronously to follow the running speed of the rolled material. The roller has a holding body that is fixed in a cantilever manner, and the holding body is moved up and down so that the roller can move up and down in the vertical direction in a plane perpendicular to the rolling material running line, and can also move laterally in the width direction of the sheet. A rolled material lifting device provided so as to be movable laterally;
Rolled material clamps are arranged in groups on both sides of the upstream and downstream sides of the rolled material lifting device, and are capable of pinching the rolled material and inverting and removing it out of the traveling line according to a command, and are movable transversely in the width direction of the sheet. an off-line device, and a control device that tracks and calculates the movement value of the rolled material connecting portion from the reference point and issues an operation timing control signal to the rolled material lifting device, the rolled material clamping offline device, and the high-speed cutting machine. A continuous hot-rolled material joint removal device.
