状体の幅寸法と一側端の蛇行とを同時に検出する
装置に関する。[Detailed description of the invention] [Field of industrial application] The present invention is based on the width dimension and meandering of one side end of a continuously running metal strip such as steel or aluminum, or a band-like material such as paper or film. The present invention relates to a device for simultaneously detecting.

For example, in a continuous galvanizing line for steel sheets, the untreated strip is rewound by an unwinding device installed on the input side, and then passed through a heat treatment process and placed in an immersion zinc bath, and then stored in a strip storage installed on the output side. The material is wound up by a winding machine via an accumulator.
ところで、従来上記の如き帯状体を巻取りする

扱も容易な前記後者の手段を採用するものであ
る。 By the way, conventional methods for winding up the above-mentioned belt-shaped body include a method of aligning the center in the width direction of the traveling belt-shaped body as a reference, and a method that is completely different from this method, in which the width of the traveling belt-shaped body is adjusted. A method of aligning the ends with one end in the direction as a reference has been adopted, but the present invention adopts the latter method, which is structurally compact and easy to handle.
この後者の巻取りのための具体的な手段は、通
常以下の通りに構成されている。 The specific means for this latter winding is usually constructed as follows.

リツプの幅方向に移動させるようにして、巻取ス
トリツプの耳揃えを行つていた。 There is a considerable distance from the input side to the output side, so detectors are placed along the stripline at key points to detect changes in the position of the end of the strip, that is, meandering of one end of the strip. In response to the output signal of the inspection device, the tension is adjusted via a bridle roll to correct misalignment in the width direction of the strip, and at the winding point, the winding machine is moved in the width direction of the strip. and was aligning the edges of the winding strip.

ラインを操業・運転していた。 In addition, a strip width dimension detector is prepared separately from the above detector on the exit side of the strip (usually the front side of the accumulator), and the temperature of the strip in the heating furnace is determined based on the results of this detector. and tension so that the width dimension of the product strip conforms to predetermined product standards and quality;
Operated and operated the line.

However, the above conventional technology has the following drawbacks. That is, a detector for detecting the end position of the strip;
Since the detector for detecting the width dimension of the strip is installed separately on the exit side of the strip, a fairly large installation space is occupied along (or around) the line on the exit side. The space required for placing and moving other equipment or for stopping and moving the strip by an operator is reduced. For example, when threading a strip at the beginning of operation, when the space is reduced, the work efficiency is poor and it takes time and requires a lot of manpower.

現状である。b Since the width dimension detector is installed only on the output side, the correlation between the width of the raw material coil set on the input side and the width of the finished product after going through the process can be checked from moment to moment. Due to this inability to understand, optimal process controls were not carried out, resulting in a decrease in the pass rate of plated coils, leading to an increase in manufacturing costs. In order to solve this problem, it has been requested to install a width dimension detector on the entrance side and, if necessary, in the middle. Currently, it has not been installed for reasons such as necessity.

蛇行（本実施例においては右端位置を示す蛇行）
信号ｅが得られる。 FIG. 3 shows an example of a signal processing circuit that processes the output signals k 1 and k 2 output from the detectors K 1 and K 2. In the figure, A 1 and A 2 are amplifiers, T is an adder,
C is a comparator and D is a reference signal source. Then, the output signals k 1 and k 2 that have passed through the amplifiers A 1 and A 2 are calculated in the adder T, that is, the output signals k 1 and k 2 that have passed through the amplifiers A 1 and A 2 are calculated in the adder T, that is, both the detectors K 1 and K 2
The value of the result of adding the number of turned-on elements is calculated for both detectors.
Subtract from the reference number of image sensors K 1 and K 2 ,
By adding a value corresponding to the distance between the two detectors K 1 and K 2 to the resulting value, a width signal w corresponding to the width dimension of the strip S is outputted. Therefore, as an example, in Figure 2,
To explain specifically using an example where the right end of the strip S is displaced to the right and the left end is in the normal running position, on the right side of the strip S, the light from the light source H is
Compared to the case where the strip is in its normal running position, the amount of the strip that passes outside this right end of the strip S decreases, and the amount that enters the image sensor element of the right detector K1 decreases; Although the number of light received by the image sensor element decreases, on the left side of the strip S, the left end is in the normal running position, so the amount of light from the light source H is the same as that in the normal running position. There is no change in the amount that passes outside the left end of S and is therefore incident on the image sensor element of the left detector K2 , and there is no change in the number of image sensor elements turned on. The number of light received by the image sensor elements of both detectors K 1 and K 2 is output as an output signal to the amplifier A 1 ,
A 2 is input to the adder T, where it is added, and the value of this addition result is subtracted from the reference number of image sensors of both detectors K 1 and K 2 . A value corresponding to the distance between 1 and K2 is added. As a result, a width signal w indicating that the width dimension of the strip S exceeds the reference dimension is output. Further, the output signal k 2 that has passed through the one amplifier A 2 is input to the comparator C, and is compared with the reference position signal d corresponding to the reference end position of the strip S that is input to the comparator C. Meandering at one end of body S (in this example, meandering indicating the right end position)
A signal e is obtained.

信号により原材料ストリツプのチエツクを行う。 The width signal w and meandering signal e from one side end are sent to a control section (not shown), and actuate a predetermined control device in the line. That is, in the line shown in FIG. 1, the detection device K installed on the entry side detects the meandering state of the strip, and also detects the coil width and checks the raw material strip based on the signal.

Even if the above-mentioned detection device is applied, the effect is great.

めの検出装置が必要となるからである。 This is because these strips undergo a greater amount of stretching due to temperature and tension than galvanized steel sheets, and there are many process sections from the input side to the output side, so there are many points where meandering occurs and width fluctuations occur. This is because a detection device for meandering correction and width measurement is required at those positions.

As explained above, in the present invention, a frame is installed in the middle of the travel path of the continuously running strip, and the frame is placed at a position corresponding to the vicinity of both ends of the continuously running strip. Detectors each detecting a change in the position of the end in the width direction are arranged, and the width dimension of the strip is calculated based on the outputs of both detectors, and the output of one of the detectors is compared with a reference signal. Since the meandering of one side end of the strip is detected, the width dimension of the strip and the meandering of one side end can be detected at the same time and at the same location by one detection device. can. Therefore, compared to the conventional method in which two detectors are installed close to each other, the required installation area is smaller, allowing for the installation of other control devices and creating more space in the work space. can.

体装置に比べて極めて安価になる。 Furthermore, by electrically processing the output signal of the detector, it is possible to reliably detect the width dimension and the meandering of one end of the strip, and the meandering of the one end of the strip can be detected. Since the meandering of one side end of the strip can be corrected, the configuration is simple and the detection cost is extremely low compared to conventional separate devices.
