ある。2. Description of the Related Art Conventionally, when a belt-shaped material such as a metal strip is supported and conveyed in a non-contact state, a levitation supporting device as disclosed in Japanese Patent Publication No. 44-11451 has been put into practical use. This levitation support device is installed so as to face the belt-shaped material to be conveyed, and has a structure in which two slits for ejecting gas toward each other are provided in a header to which high-pressure gas is supplied. The static pressure is generated between the strip-shaped material and the header by the gas from the above to float and support the strip-shaped material.

圧状態に保持することも提案されている。By the way, in the levitation support device, when the width of the strip is shorter than the length of the slit, the gas escapes from the outer edges of both ends of the strip, and a sufficient levitation force cannot be obtained.
A large amount of gas is required to obtain sufficient levitation force.
Also, if a large amount of gas escapes from the outer edges of the strips,
The belt-shaped material flaps or tilts to one side, making stable levitation support impossible. Therefore, the actual development number 59-118997
In the publication, it is proposed that the slit length be adjusted to the optimum slit length for the width of the band-shaped material by moving the cover. Further, in Japanese Patent Laid-Open No. 61-210131, a baffle plate provided with a plurality of partition plates at a predetermined interval in the conveying direction of the strip-shaped material is provided in the header to partition a static pressure area to both sides of the fluid. It has also been proposed to prevent outflow and maintain high static pressure.

目的とする。If the two known means are combined as shown in FIG. 3, it should be possible to maintain static pressure in an ideal state. In the figure, 6 is a baffle plate including a large number of partition plates 7 provided on the header 1, 3 is a side plate, and W is a strip-shaped member. However, according to the experiments, satisfactory results could not be obtained depending on the distance between the partition plates of the baffle plate and the width of the band-shaped material. As a result of examining the cause, the baffle plate 6 is fixed to the upper surface of the header 1, and therefore, as shown in FIGS.
If the width of the strip W changes as shown by, the opening area S 1 formed between the strip W and the partition plate closest to the strip edge of the baffle plate 6 changes to S 2. It turns out that it is because it is doing. Therefore, according to the present invention, even if the width of the strip is changed, the distance between the edge of the strip and the partition plates of the side plate and the baffle plate is constant,
An object of the present invention is to obtain a levitation support device for a strip-shaped material that can obtain a stable levitation support force without increasing the amount of jet gas.

たものである。In order to achieve the above-mentioned object, the present invention ejects gas toward the headers, which are installed so as to face the belt-like material to be conveyed and to which high-pressure gas is supplied, inwardly. In the levitation support device for the strip-shaped material, which is provided with two slits in the width direction of the strip-shaped material, a side plate for restricting the ejection width of the slit is provided in the header, and a predetermined interval in the transport direction of the strip-shaped material. A baffle plate consisting of a partition plate provided in, is provided so as to be movable respectively on both sides in the width direction of the strip-shaped material, and the baffle plate is attached to the side plate,
Both plates are integrally movable on both sides of the strip in the width direction.

In FIGS. 1 and 2, reference numeral 1 denotes a header, which is arranged orthogonal to the transport direction of the strip-shaped material W, and slits 2 for ejecting gas toward each other on both sides of the header 1.
Have two. Reference numerals 3 and 3 denote driving means (not shown), for example, side plates movable on the upper surface of the header 1, and a sliding portion 4 covers a part of the slits 2 and 2. Reference numeral 6 is a baffle plate, and a plurality of partition plates 7 lower than the side plates 3, three partition plates 7 in the figure, are arranged in the bottom plate 5 facing the side plates 3 and 3 in the conveyance direction of the strip W. .

In the above description, the baffle plate 6 is replaced by the side plate 3
The side plate 3 is formed integrally with the side plate 3 so as to be movable. However, both are independently movable, and the distance between the edge of the band W and the side plate 3 is changed by the band W. Good.

In a levitation support device for a strip-shaped material in which a plurality of slits are provided in the width direction of the strip-shaped material, the header is provided with a side plate that regulates the ejection width of the slit and a predetermined interval in the conveyance direction of the strip-shaped material. Since the baffle plate composed of a partition wall plate is provided so as to be movable on both sides in the width direction of the strip member or integrally with each other, the opening area between the outer partition plate of the baffle plate and the edge of the strip member is always provided. Further, the distance between the side frame and the edge of the strip-shaped material can be kept constant, and the strip-shaped material can be stably floated and supported while minimizing the loss of high-pressure gas.
