BACKGROUND ART Recently, there has been active research and development into coated metal enclosures that are constructed watertightly and airtight by seam welding coated metal materials (mainly stainless steel materials, etc.) to the inner and outer surfaces of structures. If the upper end of the joint a to be seam welded is simply cut off as shown in Figure 8, it will look like a vertical knife, which is not only extremely dangerous for construction workers, but also will cause the seam to be welded. Because of the inconvenience of cutting the cord of the welding machine, etc., it was necessary to break off the upper end of the joint part a. Folding machines have already been developed for this purpose, but they may not be able to reliably fold, or may not be able to produce good folds if the thickness of the coated metal material changes, or may cause problems during the folding process. When a problem occurs, the folding machine cannot be easily removed, resulting in a significant drop in folding work efficiency.

In this way, in the invention of claim 1, the swinging body 2 is swingably and fixedly provided with respect to the fixed main body 1, and the fixed main body 1 and the swinging main body 2 each have a plurality of groups. A folding roll for folding the upper edge of a vertical thin plate material is fixed to the lower end of each roll shaft 9, 9..., and one of the pair of folding rolls in each group is fixed to the lower end of each roll shaft 9, 9.... At least one of the main folding roll and the sub-folding roll has a diameter that becomes smaller as it goes downwards, and a worm wheel 16 is fixed to the upper end of each of the roll shafts 9, 9, and a worm wheel 16 is attached to the swinging center of the roll. Worm 17 stuck to shaft rod 3
First, by screwing the left and right worm wheels 16, 16 together and driving the shaft rod 3 with an electric motor 18, the diameter becomes smaller as it goes downward. The circumferential speed of the upper side of the rolls is higher than that of the lower side, and when the pair of folding rolls rotates, the thin plate material (joint part a) is lifted upward as the pair of folding rolls rotates. In other words, when considering a vertical thin sheet material (joint part a) as a reference, the folding roll acts as if it bites into the lower part of the thin sheet material (joint part a) while rotating, and the folding roll cuts into the thin sheet material during the folding operation. It does not easily come off from (joint part a) and prevents floating deviation, allowing extremely smooth breaking work.
The folding work efficiency can be significantly improved. In addition, in the present invention, in particular, a drive transmission structure is adopted using the worm 17 and the worm wheel 16, and the swinging body 2 can swing (open) relative to the fixed body 1 at the axis of the worm 17 (the center of the shaft rod 3). By doing so,
The worm 17 and the worm wheel 16 can be easily opened while maintaining the engaged state. Therefore, if any trouble occurs during folding work,
When the swinging body 2 is swung (opened) relative to the fixed body 1 around the shaft 3, the gap between the main folding roll and the sub-roll is widened, and the folding machine is It can be easily removed from a), which in turn can significantly improve the efficiency of the folding operation. In the past, the drive of the folding rolls had to be reversed to travel a certain length (for example, about 2 to 3 meters), which solved the disadvantage of being extremely inefficient. Even if the distance between the main folding roll and the secondary folding roll can be widened in this way, the folding rolls of the plurality of groups can be moved vertically by fixing the movable body 2 to the fixed body 1 during the folding operation. The thin plate material (joint part a) can be held well and the folding work can be performed.

Further, in the invention of claim 2, in addition to the structure of the invention of claim 1, a sliding support plate 31 is provided at a position slightly below the folding rolls of the plurality of groups.
31 to support the fixed main body 1 and the swinging main body 2, the entire load of the folding machine is supported by the sliding support plates 31, 31, and the folding rolls of the plurality of groups are made of thin plate material (the joint part a), and as a result, when the folding roll rotates and advances, a fine arc shape is formed on the flat main plate near the vertical thin plate material (joint part a). It can eliminate wrinkles and smooth the signal of the folding machine. In addition, the sliding support plates 31, 31
With the presence of the folding roll, the folding main roll and the folding sub-roll need only have a roll thickness corresponding to the folding height, which is economical. The other configurations are the same as the configuration of the invention in item 1, and the same effects are achieved.

In addition, in the invention of claim 3, the swinging body 2 is swingable with respect to the fixed main body 1, and elastically so that both the fixed main body 1 and the swinging main body 2 are in substantially close contact with each other. A plurality of groups of roll shafts 9, 9... are supported on the fixed main body 1 and the movable main body 2, respectively, and the upper end edges of the thin plate materials perpendicular to the lower ends of the roll shafts 9, 9... are broken. The rolls are fixed, and at least one of the main folding roll and the secondary folding roll of the pair of folding rolls in each group has a diameter that becomes smaller as it goes downward, and the roll axis 9,
9... Attach the worm foil 16 to the upper end of each,
The left and right worm wheels 16,1
6 are engaged with each other, and the shaft rod 3 is driven by the electric motor 18, so that even if the thickness of the coated metal material of the coated metal envelope changes, each group can be adjusted according to the plate thickness. The distance between the main folding roll and the sub-rolling roll of the pair of folding rolls can be regulated to provide a good response. A major feature of the present invention is that the breaking work can be carried out regardless of the thickness of the coated metal material of the coated metal envelope. Even if the distance between the main folding roll and the secondary folding roll can be widened in this way, the folding rolls of the plurality of groups are elastic so as to bring the movable body 2 into substantially close contact with the fixed body 1 during the folding operation. By supporting the vertical thin plate material (joint part a), the folding operation can be performed while holding the vertical thin plate material (joint part a) well. Furthermore, similar to the invention in item 1, the folding roll does not easily come off from the thin plate material (joint part a) during the folding operation, and it is possible to prevent the folding roll from floating off and deviating from the surface. The folding machine can be easily removed if necessary.

Further, in the invention of claim 4, in addition to the configuration of the invention of claim 1, the plurality of groups of folding rolls are made to repel each other in a substantially horizontal direction,
In addition, by forcing the upper roll, which bends the upper edge of the vertical thin plate material to a nearly right angle, to bounce downward, the thickness of the coated metal material of the coated metal envelope suddenly increases due to the presence of joints, etc. Even when the plate thickness becomes thicker or thinner, the distance between the folding rolls in each group changes according to the change in thickness, allowing extremely good folding work and significantly increasing folding efficiency. can. Furthermore, the other configurations are the same as the configuration of the invention in item 1, and the same effects are achieved.
