DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for treating a strip such as a steel strip, for example, a plating apparatus, a cleaning apparatus and the like, and especially to a strip treating apparatus in which homopolar electrodes as anodes or cathodes are arranged so as to face to each other in a bath tank, and a strip is travelled between these electrodes.
For the purpose of increasing production and improving productivity in the above-described strip treating apparatus, it has been required to decrease the distance between a strip and each of electrodes such as anodes or cathodes, to stir a treating solution such as a plating solution between the strip and each of the electrodes such as anodes or cathodes, and to supply ions between the strip and each of the electrodes such as anodes or cathodes. In view of these circumstances, the applicant has developed an apparatus in which insulators (stabilizers) are provided so as to be projected face to face or in zigzags on opposite inner surfaces of homopolar electrodes arranged so as to face to each other, and each of these insulators is provided with a slant face inclined from a side of the electrode toward the strip in a travelling direction of the strip (Japanese Patent Provisional Publication No. H3-20494). It became thus possible to extremely decrease the distance between the homopolar electrodes so as to remarkably improve productivity with the use of the strip treating apparatus.
However, the above-described strip treating apparatus has involved problems, and has been required to be further improved.
There is the first problem which relates to a mechanism for adjusting the distance between the electrodes. In the above-described strip treating apparatus, the distance between the electrodes is extremely short. Use of the electrodes stationarily arranged thus makes it impossible to pass a rope between the electrodes, which is to be used for passing the strip through the strip treating apparatus prior to the start thereof. The connecting portion of the strips by means of a welding and so on has a relatively large thickness. It has therefore been considered at the time of development of the apparatus that the above-mentioned connecting portion would be in contact with the stabilizer to cause the breakage thereof. For these reasons, there has been required a mechanism for opening and closing the electrodes.
There have conventionally been provided an opening and closing mechanism and operating members thereof, in which both of the electrodes were openable against each other as shown in FIG. 13, in order to secure a space necessary for an operation of passing a rope between the electrodes, which is to be used for passing the strip through the strip treating apparatus prior to the start thereof, and to prevent the welded portion of the strips from being in contact with the stabilizer during travelling of the strip.
A treating solution such as a plating solution (not shown) is filled in a vertical-pass type bath tank 1 as shown in FIG. 13. As electrodes 2, there may be used one of anodes and cathodes, or electrodes which are changeable into anodes or cathodes. The upper portions of the respective electrodes 2 are supported by means of upper electrode-holders 3. On these upper electrode-holders 3, there are provided pneumatic cylinders 4 for opening and closing the upper portions of the electrodes. The lower portions of the respective electrodes 2 are supported by means of lower electrode-holders 5. On these lower electrode-holders 5, there are provided cams 6 for opening and closing the lower portions of the electrodes. The opening or closing of the electrodes is carried out by operating all of the pair of pneumatic cylinders 4 and the pair of cams 6 for each electrode.
Both of the electrodes are movable in this manner. There has been a necessity of securing in the bath tank 1 a space necessary for moving also the electrode arranged farthest from a conducting drum 7, i.e., the electrode 2a arranged at the side of the wall of the ba
