BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously applying a photosensitive liquid to both sides of a rolled metal sheet.

[0002]

2. Description of the Related Art Conventionally, an apparatus for continuously applying a photosensitive liquid to both sides of a rolled metal sheet is disclosed in, for example, Japanese Utility Model Publication No. Sho 62-235.
No. 75, a photosensitive liquid is put in a storage tank, a thin metal plate is immersed, and squeezed by a squeeze roll to apply the photosensitive liquid. Since the photosensitive solution is always used by being applied to the metal material, the new photosensitive solution is constantly supplied from the supply tank to the storage tank.

[0003]

[Problems to be Solved by the Invention] However, during use, the photosensitive solution in the storage tank gradually becomes old even if a new photosensitive solution is constantly supplied, and the photosensitive solution is entirely removed. However, there is a problem that the sensitivity of the photosensitive solution is lowered due to fatigue.

[0004] The present invention has been developed to solve the above problems.
An object of the present invention is to provide an apparatus capable of constantly applying a new photosensitive liquid to both surfaces of a metal material.

[0005]

According to the present invention, two frames are provided facing each other, a pair of squeeze rolls are mounted on an upper portion between the frames, and a lower portion is mounted on a lower portion between the frames. A guide roll, a new liquid tank mounted so as to surround the squeeze roll between the frames, a liquid storage tank surrounding the two frames, and a position above the new liquid tank And a liquid replenisher for replenishing the new coating liquid, wherein a bottom of the new liquid tank has a slit with a packing member for drawing the metal sheet from a guide roll, and the photosensitive liquid is applied to the metal sheet. Device.

Further, there is provided an apparatus for applying a photosensitive liquid to a thin metal plate, wherein the liquid storage tank is movable up and down.

[0007]

[Function] The photosensitive liquid is squeezed with a squeeze roll on both sides of the metal material. This is a new liquid tank with a small capacity. A photosensitive liquid can be applied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to FIGS.

As shown in FIGS. 1 and 2, a pair of squeeze rolls 13 are mounted on an upper portion between two frames 12 which are mounted on opposite sides of the support 11 and provided to face each other.
The interval between the pair of squeeze rolls 13 can be freely adjusted (not shown). A guide roll 14 is attached to a lower portion between the frames 12.

A new liquid tank 15 having an upper opening is attached between the frames 12 so as to surround a pair of squeeze rolls 13 as shown in FIG. It is preferable that the new liquid tank 15 be removable. The new liquid tank 15 may be attached to the liquid storage tank 16. The new liquid tank 15 has a notch 22 for overflow in a part of the wall surface as shown in FIG. 4 and a slit 20 at the bottom as shown in FIG. As shown in FIG. 8, two packing members 21 in which the elastic rubber 19 is attached to the metal fittings 20 are prepared in the slit 20, the ends of the elastic rubber 19 are aligned with each other, and the ends are inserted as shown in FIG. The metal fitting 20 is fixed to the bottom of the new liquid tank 15 with a screw or the like. The new liquid tank 15 may be configured to be vertically split into two from the slit 20. For example, it is designed to be broken from the dotted line portion in FIG. By doing so, the new liquid tank 15 can be assembled after the metal thin plate 18 is set in the coating device 10. However, the present invention is not limited to this structure.

As shown in FIGS. 1, 2, and 3, two frames 12 having a pair of squeeze rolls 13, guide rolls 14, and a new liquid tank 15 are provided between the two frames 12. So that the liquid storage tank 1 is open at the top
6 is attached to the support 11.

The liquid storage tank is made movable up and down. The liquid storage tank can move up and down, so if you lower the liquid storage tank,
It becomes easier to clean guide rolls, squeeze rolls, new liquid tanks, and the like.

Above the new liquid tank 15, the tip of a liquid replenisher 17 for replenishing a new coating liquid is located as shown in FIG.

As shown in FIG. 3, the liquid level of the photosensitive liquid in the liquid storage tank 16 is set to be higher than the position of the slit of the new liquid tank 15. In this way, a state where there is no air between the new photosensitive solution and the photosensitive solution in the solution storage tank 16 is obtained. New liquid tank 15
The new photosensitive solution is replenished from the solution replenisher 17, and the overflowed new photosensitive solution falls from the overflow notch 22 into the solution storage tank 16.

As shown in FIG. 3, the apparatus 10 comprises a metal sheet 18.
Enters the liquid storage tank 16 from diagonally above, and the guide roll 14
And is drawn upwards, passes between the packing members 21 of the slits 20 of the new liquid tank 15, enters the new liquid tank 15, and further passes through the squeeze roll 13, so that a predetermined amount of light is exposed to the metal sheet 18. The liquid is applied.

[0016]

[Effect of the Invention] With the above-described apparatus, the new liquid tank may be a tank having a size just to enclose a pair of squeeze rolls. Therefore, the new liquid tank can be made smaller, and the new liquid tank can be continuously formed on both sides of the metal sheet. A photosensitive liquid can be applied. In an apparatus such as the conventional example, even if an attempt is made to reduce the size of the tank, the tank needs to have a size enough to surround the pair of squeeze rolls and the guide roll, and therefore the tank does not become small.

Since the new liquid tank is provided with a packing member, the new photosensitive liquid can be kept in the new liquid tank even when a thin metal plate is run. If the liquid leaks, it just enters the liquid storage tank.

By using a double type tank in which a new liquid tank with a packing member is located above the inside of the liquid storage tank, a drawback that can occur when the coating apparatus is a single liquid tank with a packing member alone, for example, a packing portion That the liquid leaks from and that air is drawn in along with the metal sheet when running the metal sheet,
Can be prevented. In other words, even if the liquid leaks, it will only enter the liquid storage tank, and since the photosensitive liquid is filled in both tanks and there is no air in the slit part with the packing member of the new liquid tank, the metal thin plate There is no need to worry about drawing air into the new liquid tank.

Since the thin metal sheet is guided into the new liquid tank through the slit with the packing member of the new liquid tank, most of the photosensitive liquid on the surface of the thin metal sheet is scraped off by the packing of the new liquid tank, but a small amount of the remaining photosensitive liquid is removed. The new liquid can improve the wettability of the new photosensitive liquid.

Since the liquid storage tank can be moved up and down, lowering the liquid storage tank makes it easier to clean guide rolls, squeeze rolls, new liquid tanks, and the like.
