Abstract

(57) [Summary] [Purpose] The floating conveyance device for strip-shaped objects is equipped with a side seal plate, but there is a gap between the side seal plate and the floater due to the design, and a gap is formed due to thermal expansion in a high-temperature atmosphere.
This causes biting of the edges of the strip, causing scratches. [Structure] Side seal plates with convex portions on both sides of the floating conveyance device for strips are fitted into grooves provided on the floater,
When the side seal plate is made slidable, the convex portion of the side seal plate prevents the edge of the band from getting caught in the gap between the side seal plate and the floater.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a non-contact transport method for conveying strips such as steel strips, paper, and plastic films. The present invention relates to a floating support device.

0002

[Conventional technology]

To transport the strip without contact, a fluid cushion is installed between the strip and the floater. A floating support device that provides a levitation effect is known. For example, in Utility Model Publication No. 57-11971, as shown in FIG. Non-contact type with fluid ejection holes 4 drilled in the guide surface 3 of the main body 1 having a sealed pressure chamber 2 A support device has been proposed. 6 is a running strip, 9 is a side guide, and 10 is a moving rod of the side guide 9.

0003

[Problem that the idea aims to solve]

When a floating conveyed object meanderes, the floating fluid pressure on the meandering side increases and restores the meandering. Although side guides (hereinafter referred to as side seal plates) are effective for There is a gap between the seal plate and the main body (hereinafter referred to as the floater) due to machining, especially when the In a warm atmosphere, a gap is formed in consideration of thermal expansion. By the way, in the case of re-floating after the conveyed object has stopped levitating, the edge of the conveyed object is close to the side seal plate. If it gets caught in the gap between the objects, it becomes difficult to re-float the object, and it also causes damage to the transported object.

0004

[Means to solve the problem]

The present invention solves the above-mentioned problems, and the gist is to remove the floater from the floater. In a floating support device that supports a strip-shaped object in a non-contact manner by injecting fluid onto one side of the strip-shaped object, Side seal plates with convex parts are provided on both sides of the moving line of the floater, and A concave groove that fits into the convex part of the side seal plate is carved to allow the side seal plate to slide freely. This is a floating support device characterized by:

[0005] The present invention will be explained below based on the drawings. Figure 1 shows an embodiment of the present invention in a perspective view, showing a 180° turning floater, and Figure 2 shows an embodiment of the present invention. FIG. In the figure, the floater 1 forms an arcuate guide surface 3 and the flow It has a body introduction tube 5, and a floating nozzle 4 is bored therein. The side seal plates 9 of the present invention are installed on both sides of the floater 1 in the movement line of the strip 6. Although it is cut off, a protrusion 11 is provided on the side seal plate 9. Also floater 1 A concave groove 10 that fits into the convex portion 11 is carved in the groove.

[0006] Therefore, the side seal plate 9 is slidable in the width direction of the floater 1. Also, convex part 1 1 is provided protrudingly on the side seal plate 9 and is fitted into the groove 10, so that the strip 6 is floating. The upper part is stopped and rests on the guide surface 3 of the floater 1, and the side seal plate 9 and the flow Even if it tries to get caught in the gap with the side seal plate 9, the convex part 11 of the side seal plate 9 prevents the The body 6 does not get caught in the gap. In other words, the gap becomes a hindrance to the resurfacing of the strip 6. Since there are no scratches, the band 6 is prevented from being caught, and therefore no flaws occur.

[0007] Figure 3 shows an example of a 90° redirection floater.

[0008] 4 and 5 show still another example of the present invention, in which the guide surface 3 of the floater 1 is flat. It is a surface. In this example as well, when re-floating the strip 6, even if the floater 1 and the Even if a gap is formed between the side seal plate 9 and the side seal plate 9, the convex portion 11 of the side seal plate This is effective in preventing the band 6 from getting caught in the gap.

[0009] The convex part of the side seal plate and the concave groove of the floater form a pair on both sides, but it is preferable that Preferably, two or more pairs should be provided at appropriate intervals on the side seal plate. The present invention has been explained above using examples of strip-shaped bodies, but paper, plastic films, etc. It is also effective in conveying belt-shaped objects.

0010

[Effect of the idea]

This invention forms a convex part on the side seal plate and a concave groove on the floater, and Since the doshield plate is made to be slidable, there is no possibility of flaws occurring in the strip when it is re-floated. It has the effect of preventing
