その際、生産性向上のために特開昭51−70424に示されているように焼結基板を巻回体の状態で一連の浸漬・乾燥・アルカリ処理・水洗の各工程を施す方法が提案されている。この方法では、焼結基板をステンレス製スプリングなどの間隔保持体により所定極板間隔を保持して巻回し、巻回体の状態で含浸することにより大量処理を可能にしている。この支持リールは図4および図5に示すように、主軸11の両端に配設された支持部12a、12bを有している。またこれら支持部には、主軸を中心として放射状にリブ13が配設されており、巻回された焼結基板7の側端部がこれらリブ13によって支持されるようになっている。通常、支持リールは主軸11が直立するような態勢で使用されるが、リブ13による部分的支持により、巻回された焼結基板の側端部の全辺が支持部と接触することがない。これにより、焼結基板側端部の損傷が防止でき、かつ焼結基板を処理液に浸漬しても処理液などの循環が妨げられないようになっている。しかしながら、近年、更なる大量処理が求められるようになり、焼結基板の幅広化、長尺化が更に推し進められるようになった。この結果、リブにかかる焼結基板の重みが増大し、特に保持体外周部においてはリブの間隔が広がることから、焼結基板が自重で変形し、巻回体の真円度が維持できなくなるといった問題が生じるようになった。これにより、焼結基板同士が接触し、その部分で液体あるいは気体の流通が悪くなり、極板表面に汚れが生じたり、均一な表面処理ができなかったりすることにより、品質低下の原因となっていた。[0009]
At that time, as shown in JP-A-51-70424, in order to improve the productivity, a method is proposed in which the sintered substrate is subjected to a series of steps of immersion, drying, alkali treatment and water washing in the state of a wound body. It is done. In this method, a large amount of processing can be performed by winding the sintered substrate while maintaining a predetermined electrode plate distance by a spacer such as a stainless steel spring and impregnating the sintered substrate in the state of a wound body. As shown in FIGS. 4 and 5, the support reel has support portions 12 a and 12 b disposed at both ends of the main shaft 11. In addition, ribs 13 are radially disposed around the main axis in these supporting portions, and the side end portions of the wound sintered substrate 7 are supported by the ribs 13. Usually, the support reel is used in such a manner that the main shaft 11 is erected, but partial support by the rib 13 prevents all sides of the side end of the wound sintered substrate from contacting the support. . Thereby, damage to the sintered substrate side end can be prevented, and even if the sintered substrate is immersed in the treatment liquid, circulation of the treatment liquid and the like is not hindered. However, in recent years, become further mass treatment is required, broadening of the sintered substrate, lengthening becomes so that is further promoted. As a result, the weight of the sintered substrate applied to the ribs is increased, and in particular at the outer peripheral portion of the holder, the distance between the ribs is increased, so the sintered substrate is deformed by its own weight and the circularity of the wound body can not be maintained. The problem came to occur. As a result, the sintered substrates come in contact with each other, the flow of the liquid or gas becomes worse at that portion, the electrode plate surface becomes dirty, or uniform surface treatment can not be performed, which causes quality deterioration. It was

そこで、上記焼結基板同士の接触を防ぐために、リール中心部の軸受型鍔部から放射状に延び出たリブ上に渦巻き状に極板支持ガイド片を固定し、帯状の焼結基板を支持する極板支持ガイド片相互の間隔を、鍔部に近い巻き初め部分で広くし、外周部に近い巻き終わり部分では狭くして巻き取る方法が提案されている(特開平11−213997)。[0010]
Therefore, in order to prevent contact between the sintered substrate, an electrode plate support guide piece fixed to the spiral on ribs extending out radially from the bearing-type flange portion of the reel center to support the belt-like sintered substrate A method has been proposed in which the distance between the electrode plate support guide pieces is increased at the winding start portion near the buttocks, and the winding end portion near the outer periphery is narrowed for winding (Japanese Patent Application Laid-Open No. 11-213997).

【発明が解決しようとする課題】
しかし、そのような方法では、巻回体中心部での巻回ピッチが大きくなるため焼結基板の巻長さが減少し、生産性向上効果を十分に発揮し得ず、又、巻回体の外周部と内周部で焼結基板同士の間隔が異なり、液体、気体の流通が均一にならないなどの問題があった。[0011]
[Problems to be solved by the invention]
However, such a method reduces the winding length of the sintered substrate for the winding pitch at the wound body center becomes large, fully productive improvement Eze, also wound body the different spacing of the sintered boards at the outer peripheral portion and the inner peripheral portion, there liquids, circulation of gas, such as not uniform problems.

したがって、本発明の支持リールによれば、巻回体内周部から外周部にわたって巻回体を構成する焼結基板などの帯状体の距離を短く保ったまま、支持することができるため、巻回体が全体にわたって真円に近い形状を維持することが可能となる。一方、内周部では必要以上にリブが密集することが無いため、液体、気体の流通が悪くなることもない。従って、液体や気体の通過を遮断することのないように配置することができる。その結果、巻回体全長にわたって必要最低限の間隔で巻回することができ、一度に処理し得る最大量の処理を行なうことが可能となり、生産性が飛躍的に向上する。また、十分に均一な処理を行なうことが可能となる。[0016]
Therefore, according to the support reel of the present invention, while maintaining a short distance of the belt, such as a sintered substrate of the wound body over the outer periphery of the winding body periphery, it is possible to support, wound It is possible for the body to maintain a near-round shape throughout. On the other hand, in the inner peripheral portion, since the ribs are not densely packed more than necessary, the flow of the liquid and the gas does not deteriorate. Therefore, it can be arranged so as not to block the passage of liquid or gas. As a result, it is possible to wind at the necessary minimum intervals over the entire length of the wound body, and it is possible to perform the maximum amount of processing that can be processed at one time, and productivity is dramatically improved. In addition, it becomes possible to perform sufficiently uniform processing.

かかる構成によれば、領域面積が小さくなる内周側でリブが少なく、領域面積の大きくなる外周側ではリブが多くなる構造の支持リールを用いているため、この支持リールは、外周側の機械的強度が高められ、面全体にわたって同程度の機械的強度をもつものとなっている。したがって巻回体内周部から外周部にわたって巻回体を構成する帯状焼結基板の距離を短く保ったまま、全体にわたって真円に近い形状を維持することが可能となる。一方、内周部では必要以上にリブが密集することが無いため、液体、気体の流通が悪くなることもなく表面状態の良好な電極基板を形成することが可能となる。したがって、巻回体全長にわたって必要最低限の間隔で巻回することができ、一度に処理し得る最大量の処理を行なうことが可能となり、生産性が飛躍的に向上する。[0022]
According to this configuration, since the support reel having a structure in which the rib is small on the inner circumferential side where the area area is small and the rib is large on the outer circumferential side where the area area is large The mechanical strength is enhanced, and the mechanical strength is the same as that of the entire surface. Thus while maintaining short distance of the strip sintered substrate constituting the wound body over the outer periphery of the winding body periphery, it is possible to maintain the shape close to a true circle throughout. On the other hand, in the inner peripheral portion, since the ribs are not densely packed more than necessary, it is possible to form an electrode substrate having a good surface condition without deterioration of the flow of liquid and gas. Therefore, it is possible to wind at the necessary minimum intervals over the entire length of the winding body, and it becomes possible to perform the maximum amount of processing that can be processed at one time, and the productivity is dramatically improved.

The relationship of A to S is shown in FIG. In addition, in FIG. 6, S in the part in the largest rib contact space | interval is normalized and shown to 100%.
