般的な方法である。2. Description of the Related Art For example, when a brazing filler metal piece having a thickness of 10 to 100 μm is manufactured, first, a raw material metal is melted so as to have a predetermined alloy composition and cast into an ingot, and the ingot is rolled to a desired thickness by a rolling mill. It is a general method to roll the foil into a foil having a desired shape and then punch the obtained foil with a punching die set in a press.

レンなどの有機溶剤を用いていた。[0003] In the above process, a lubricating oil is usually used for rolling, but no oil is used for punching. This is because if punching is performed with the oil film attached to the foil, dust, dust, or minute metal pieces tend to adhere to the foil surface, and if this is pressed onto the brazing material piece, the appearance becomes poor. Therefore, when oil is used for rolling,
It is necessary to wash and remove the oil film attached to the foil before punching. For such foil cleaning, the conventional method shown in FIG.
A cleaning device such as that shown in is used, and the cleaning liquid is Freon 113.
Or an organic solvent such as 1.1.1 trichloroethane or trichloroethylene was used.

The foils 2 sequentially fed from the cleaning tank 4 are guided into the cleaning tank 4 by the two dipping rollers 3 and immersed in the cleaning liquid. The ultrasonic film is applied to the foil 2 to remove the oil film, and the foil 2 is pulled out from the cleaning tank 4. The cleaning liquid 6 on the surface of the foil 2 is wiped off by the wiping cloth 6 and then wound on the winding spool 7.

イルの腐食や水シミなどの不良を招くことになる。Problems to be solved when methylene chloride is used as a cleaning liquid include a boiling point of about 40 ° C., which is lower than that of trichloroethane, and a large latent heat of vaporization. Therefore, when methylene chloride is put into the cleaning device shown in FIG. 2, the cleaning liquid attached to the foil surface when the foil 2 comes out of the cleaning tank 4 evaporates before being wiped off by the wiping cloth 6. At this time, the foil surface is excessively cooled in order to remove a large amount of heat of vaporization from the foil, so that moisture in the atmosphere is condensed and adheres to the foil surface, which causes corrosion of the foil and water stains. It will lead to defects such as.

An immersion roller for introducing and immersing the fed metal foil into the cleaning tank, an ultrasonic wave generator installed in the cleaning tank to promote cleaning, and an upper surface of the foil pulled up from the cleaning liquid surface. An upper surface draining roller for contacting and draining, a lower surface draining roller provided on the downstream side of the upper surface draining roller for contacting and draining the lower surface of the foil, and a downstream side close to the lower surface draining roller. And a wiping device with a heater for wiping off the cleaning liquid film remaining on the foil surface.

消されるのである。By placing the liquid draining rollers on the upper and lower surfaces in front of the wiping device, most of the methylene chloride adhering to the foil surface and being pulled up is drained and returned to the cleaning tank. Although the thin liquid film still remaining is removed by the wiping device, only the wiping cloth lowers the ambient temperature due to the evaporation of methylene chloride adhering to it and causes dew condensation. Therefore, in the present invention, this wiping cloth is used by being wound around the heater. This heater supplements the heat of vaporization, effectively prevents dew condensation, and eliminates the cause of poor cleaning.

The washing tank 4 used in the present invention is preferably a rectangular parallelepiped stainless steel tank, and is filled with methylene chloride so that the ultrasonic generator 5 and the dipping roller 3 are completely immersed in the liquid surface.
It is desirable to arrange the upper surface liquid draining roller 8 so that the lower end thereof slightly contacts the liquid surface. This is because when the liquid draining roller 8 separates from the liquid surface, the vaporization heat is taken away when the liquid film that has been drained and adhered to the roller 8 is evaporated, and the temperature is below the dew point to cause dew condensation. When the liquid draining roller 8 is arranged so as to slightly contact the liquid surface, even if the liquid film attached to the roller 8 evaporates, heat is replenished from the cleaning liquid in contact therewith, so that dew condensation does not occur.

うにするのが望ましい。The lower surface liquid draining roller 9 is arranged on the downstream side of the upper surface liquid draining roller 8 so that its lower end slightly contacts the liquid surface for the same reason as in the case of the upper surface liquid draining roller 8. The rollers 3, 8 and 9 are Teflon, the bearing is Rulon, and the shaft supporting these rollers is preferably made of stainless steel. Further, it is desirable that the immersion roller 3 and the liquid draining rollers 8 and 9 can be adjusted in position by a stainless steel arm.

使用時はフォイル２を挟み込む。The wiping device of the present invention is a device in which a wiping cloth 6 is wound around a heater 10 and is inclined so as to be parallel to the drained foil 2 and a lower surface draining roller 9 is used.
Install as a pair as close to each other as possible. It is suitable that the heater main body is made of a linear heating element in a zigzag shape in parallel and wrapped in an insulator to form a plate, which is embedded in a rectangular parallelepiped phenol resin plate provided with a recess into which the heater plate can fit. It is appropriate to cover the heater side with a copper plate to make the heat conduction uniform. This copper plate side is turned to the foil 2 side,
When using, sandwich the foil 2.
