関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for stopping the running of a continuous steel strip processing line, and more particularly to a method for stopping the running of a continuous steel strip processing line, and more particularly, to a method for stopping the running of a continuous steel strip processing line, which can accurately stop necessary parts at fixed positions.
銅帯の連続処理ラインにおいては、溶接による溶接部あ

の近傍にパンチャーにより被処理部指示用のパンチ孔を
あけることが多い。In a continuous processing line for copper strips, punch holes are often punched near the welded parts or defective parts to indicate the parts to be processed.
例えば溶接部の手入れ装置を備えた処理ラインでは、溶

置により検出し、この検出信号に基づき手入れ装置の直
下に溶接部を停止場せることになる。For example, in a processing line that is equipped with a weld care device, the weld must be precisely stopped directly below the care device. in this case,! When the belt is welded, a key metal punch is first punched, and the entire punch hole detection device detects this at the entry side of the care device, and based on this detection signal, the welding part is stopped immediately below the care device.
なお、パンチ孔以外の方法として、溶接部全直接検出す

性に乏しい。またテレビ画像処理による方法もあるが、
装置が大規模になシ設備費が高い。従って上記のパンチ
孔による間接方法が一般的である。As a method other than punch holes, there is also a device that directly detects the entire weld, such as a weld detector using eddy current, but it is not reliable. There is also a method using TV image processing,
The equipment is large-scale and equipment costs are high. Therefore, the above-mentioned indirect method using punch holes is common.
このようにパンチ礼法が一般に採られているが。In this way, punch etiquette is generally adopted.

ていた。Conventionally, a photoswitch 2 as shown in FIG. 1 has been used to detect punch holes. Punch hole 6 drilled in steel strip 4
When the light passes between the floodlight 8 and the photoswitch 2, the light that was previously blocked by the steel strip 4 passes through the punched hole 6, making the photoswitch 2 visible. Based on this signal, the time required for the weld to come directly under the care device is calculated based on the distance between the detection device and the care device, the distance between the weld waist and the punch hole, and the line running speed. The line was placed at a stop so that the process 2 was directly below the equipment.

作業を行う必要があり、生産性を阻害すると同時に作業
者の負担を大きくする問題点があった。However, with this conventional method, the punch hole detection accuracy is limited to ±5 degrees, and a pulse transmitter attached to a conveying device such as a roll is usually used to detect the loose line speed. If the copper strip slips with respect to the conveying device, the stopping accuracy will further deteriorate. Therefore, in the past, it was necessary for the operator to finally correct the welded part so that it was directly below the welding device, which had the problem of hindering productivity and increasing the burden on the operator.

向に配列されている。a step of calculating the total transmission time of a running stop signal to stop the steel strip immediately below the processing position of all the processed parts from the four items, and transmitting all running stop signals at the transmission time from the running control device of the processing line to stop the steel strip. The step of completely stopping the processing line, and the method of stopping the running of a continuous steel strip processing line, which is characterized by the following steps, will be explained with reference to FIG. 2: The entire apparatus used in the method of the present invention. FIG. 2 shows a state in which the punched hole 6 of the steel strip 4 passes through the entire area where the projector 8A and the image sensor 10 are installed. In the image sensor 10 according to the method of the present invention, elements consisting of multi-bit diodes are arranged in the line running direction so that the moving punch hole 6 can be continuously detected.

The signal from the arithmetic unit 12 is sent to the transport roll 16 via the travel control device 14. The configuration is such that the drive motor 18 can be controlled.

出力する。The details of the method of the present invention using the above-mentioned apparatus will be explained based on examples. As the steel strip 4 runs, punch holes 6 (usually 12
m+diameter) also moves in the same way. Once the punch hole 6 hits the image sensor 10, it will not be blocked by the steel strip 4 until now.
The light from the light projector 8A passes through the punched hole 6, stimulates all the elements of the image sensor 10 corresponding to the punched hole 6, and is output.

ものがあるためであシ、従って標準出力０．３Ｖ以上を
もって出力の有無を演算装置１２に判断させればよい。As the punch hole 6 moves, the sensor elements outputting n also move one after another in the advancing direction. At this time, the output waveform of the image sensor 1O moves as shown in FIG. Therefore, the time tkt from when the first element of the image sensor 10 outputs output to when the last element stops outputting the image sensor 1
The arithmetic unit 12 calculates the moving speed of the punch hole 6, that is, the running speed of the steel strip 4 by calculating the length of the known image sensor 10 using the output signal of the arithmetic unit 12. Since the running speed based on this calculation can be directly determined from the moving speed of the punch hole 6, the influence of slipping of the steel strip 4, which has been a problem with conventional line speed detection pulse transmitters, is completely eliminated, and the detection accuracy is It is also equivalent to 1 bit of feldspar, so it is very accurate. For example, long explosion 300 5 width J4 fight, number of bits 512
If the image sensor is -10, the resolution is 300■1
512=0.6 tag, which greatly improves accuracy compared to conventional photoswitches. Note that the output when the image sensor 10 received the light sound from the light projector 8A was 0.5V, and the nozzle level was 0.05V. Also, the output waveform is almost trapezoidal as shown in Figure 3, but this is because some of the light from the projector 8A is incident obliquely, so the output has a standard output of 0.3V or more. What is necessary is to have the arithmetic unit 12 determine the presence or absence of the .

ンチ孔６の中心位置を演算する。In addition, in order to stop accurately, it is necessary to know the center position of the edge hole 6, so the calculation unit j2 calculates the number of elements that the image sensor 10 simultaneously receives and outputs from the punch hole 6. The center position of the punched hole 6 is calculated by determining the diameter of the punched hole 6 and dividing it by half.

要であり直ちに被処理部の処理ができた。The travel control device 14 receives notification of the travel stop signal transmission time from the arithmetic device 12 and stops the drive motor 18 at the specified time, and the processed portion of the steel strip 4 is placed directly under the processing device with an excellent stopping accuracy of ±1 inch. It stopped. Therefore, there was no need to correct the stop position, and the part to be processed could be processed immediately.
