Abstract

PURPOSE: To reduce the amount of use of washing solution by removing and recovering the washing solution adhered to a hoop material after washing without being gasified. CONSTITUTION: An upper case 10 is connected with a lower case 11 at one point by a pin 12, and the total weight of the upper case 10 with various parts incorported therein is supported by a compression spring 13 at another point. The upper case 10 and the lower case 11 are respectively provided with a press roller 5 for pressing a hoop material 1, a spur gear 6 for transmitting rotating force to a liquid removing roller by the press roller 5, a shaft 7 for supporting the liquid removing roller 4, a bearing 8 for the shaft 7 and a stop ring 9. A rubber or plastic is used as a material for the purpose of reducing the weight of the spur gear 6 and the liquid removing roller 4 and preventing the damage to the hoop material 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recovering a cleaning solution adhering to a hoop after cleaning when degreasing and cleaning a hoop material.

[0002]

2. Description of the Prior Art Press oil adheres to the hoop material, which is a product after the hoop material is continuously punched by a press, and degreasing cleaning is performed to remove the press oil.
If the cleaning solution used at that time is dried while attached to the hoop material, the cleaning solution will be consumed and the drying performance will be adversely affected. Therefore, conventionally, the cleaning solution is removed by blowing air, and as shown in FIG. A method of sandwiching the hoop material 1 from above and below with a plain roller 3 and rotating a smooth liquid removing roller in the same direction as the moving direction of the hoop material to remove the cleaning solution 2 has been used.

[0003]

However, the method for blowing off the cleaning solution by air blow is the best method from the viewpoint of removing the cleaning solution in the sense that the hoop material is not easily scratched. It is easy to vaporize, and it is very difficult to recover the vaporized gas of the cleaning solution, which is not preferable as a cleaning solution recovery method.

Further, in the cleaning solution removing method using the plain roller, the cleaning solution escapes in the width direction of the plain roller as shown in FIG. 3, but the cleaning solution is plain because the plain roller rotates in the same direction as the moving direction of the hoop material. After being rotated, the hoop material under the roller was drawn in, and a considerable amount of unremoved material was left, which was also insufficient as a solution recovery method.

An object of the present invention is to reduce the amount of cleaning solution used by removing and recovering the cleaning solution adhering to the hoop material after cleaning the hoop material with a solvent without vaporizing it. It is to provide a method for collecting a hoop material cleaning solution.

[0006]

The gist of the present invention is based on the same principle as that of cutting with a milling cutter, and the hoop material is sandwiched from above and below by a liquid removing roller having a helical angle like a helical gear. The cleaning solution is scraped off by rotating the roller in the direction opposite to the traveling direction, and the cleaning solution is caused to flow out in one direction by the twisted groove of the helical gear removal roller.

That is, the above object of the present invention is to provide a method for collecting a cleaning solution after cleaning a hoop material with a solvent, in which a pair of helical gear-shaped liquid removing rollers are arranged above and below the hoop material so that the hoop material can be lightened. A method for recovering a cleaning solution for hoop material, comprising rotating the pressing solution in a direction opposite to the direction in which the cleaning solution is fed to the hoop material at a peripheral speed equal to or higher than the feeding speed of the cleaning solution.

The method for recovering a hoop material cleaning solution according to claim 1, wherein the rotational speed of the helical gear-shaped liquid removal roller is increased by gear shifting.

Is achieved by

FIG. 2 shows the principle of the cleaning solution removal of the present invention. In order to remove the cleaning solution 2 adhering to the hoop material 1, the hoop material 1 is sandwiched from above and below by the helical-shaped liquid removal rollers 4 arranged above and below the hoop material 1, and the liquid removal roller 4 is attached to the hoop material 1. The cleaning solution 2 adhering to the hoop material 1 is scraped off by rotating in the direction opposite to the traveling direction. The removed cleaning solution 2 flows out along the twist groove of the liquid removing roller 4 in, for example, the right direction in FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a liquid removing device. The upper case 10 and the lower case 11 are connected at one place by a pin 12, and the other place supports the weight of the entire upper case 10 in which various parts are assembled by a compression spring 13. The upper case 10 and the lower case 11 respectively support a pressing roller 5 for pressing the hoop material 1, a spur gear 6 for transmitting a rotational force from the pressing roller 5 to the liquid removing roller 4, and a liquid removing roller 4. A shaft 7, a bearing 8 for the shaft, and a stop ring 9. The spur gear 6 and the liquid removing roller 4 are preferably made of rubber or plastic so as to reduce the weight and prevent the hoop material 1 from being damaged.

When the hoop material 1 is sandwiched between the pressing rollers 5 from above and below, the pressing roller 5 rotates along the moving direction as the cleaning of the hoop material 1 progresses. This rotational force is transmitted to the liquid removing roller 4 through the spur gear 6, and the liquid removing roller 4
Is rotated in the direction opposite to the advancing direction to remove the attached cleaning solution 2. The pressing force of the liquid removing roller 4 can be adjusted by interposing a compression spring 13 between the upper case 10 and the lower case 11 so that the liquid removing roller 4 is not strongly pressed against the hoop material 1. Further, by combining the spur gear 6 with a different number of teeth, the peripheral speed of the liquid removing roller 4 can be increased and the liquid removing efficiency can be increased.

The present invention is applied to the solvent cleaning of the hoop material, but as a modification, it can also be applied to the recovery of the deposition solution after the plating processing of the hoop material.

[0014]

According to the method for recovering the hoop material cleaning solution of the present invention, since the amount of vaporizing the solution is not so large as in the case of air blow, the amount of solution removed and recovered is increased, and the amount of cleaning solvent used can be reduced.
