方法及び装置を提供することにある。The above-mentioned thermal spraying method is excellent in forming a film on the whole object, but it is not easy to form a film such as a metal on only a part of the object. . When spraying only a part of the object in this way, a method of narrowing the spray diameter by narrowing the spot diameter of the spray, or a shielding plate that exposes only a part of the object to be sprayed is placed on the object. For example. However, the method for narrowing the spot diameter of the thermal spraying cannot be used when the distribution of thermal spraying is not allowed even slightly outside the spot.On the other hand, the method using the shielding plate, because of the thermal spray coating accumulated on the shielding plate, When spraying multiple objects, the spraying path to the object is disturbed, and there is a disadvantage that the spray boundary gradually becomes inaccurate and the accuracy as a processed product decreases. . Further, as a method of removing the thermal spray coating accumulated on the shielding plate, when performing the thermal spraying work manually, it is possible to remove the thermal spray coating by cleaning the shielding plate once and so on. In thermal spraying, it is impossible to clean the shield plate once. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to form a sprayed material coating having a high-precision boundary on a part of the surface of the object, thereby eliminating the need for the sprayed material of the object. An object of the present invention is to provide a masking method and apparatus in thermal spraying for automatically scraping and removing a thermal spray material deposit attached to a shielding member when spraying a thermal spray material by shielding a portion with a shielding member.

しにくくなる。According to the method and apparatus for masking in thermal spraying according to the present invention described above, an accurate thermal spraying range is always formed on the target by the shielding member, so that a high target is obtained. Partial thermal spray material coating can be formed with high accuracy. In addition, if the shielding member is formed of a belt, there is no need to replace the shielding member even if the size of the object is different, and the versatility is excellent. Further, if the shielding member is always moved between the object spraying position and the retreat position, the shielding member can also be moved while the object is traveling, so that the spraying operation on the object and the deposition on the shielding member can be performed. The object scraping operation can be performed simultaneously, and the thermal spraying efficiency can be increased.
In addition, if the shielding member is continuously supplied to the target spraying position by using a belt-shaped shielding member, the position of the shielding member is particularly considered if the target is positioned at the target spraying position. Spraying can be performed immediately without increasing the spraying efficiency. In addition, the moving direction of the shielding member and the moving direction of the target object are reversed, or the moving speed of the shielding member and the moving speed of the target object are relatively different from each other, so that the moving direction of the shielding member and the target object is over. The sprayed material is less likely to adhere.

にまたがって溶射金属等が付着しにくくなる。According to the above embodiment, the object 10 to be sprayed is masked by the belt-shaped shielding plates 30 and 31, and after the metal spraying, the shielding plates 30 and 31 are moved from the object spraying position to the retreat position. By removing the metal by the scraping means 40, the sprayed boundary of the object 10 can always be kept accurately. Further, since the belt-shaped shielding plates 30 and 31 always travel between the object spraying position A and the retreat position B, the shielding plates 30 and 31 also travel while the object 10 travels by the moving means 11. Object 1
The spraying operation for zero and the scraping operation by the scraping means 40 can be performed simultaneously, and the metal spraying efficiency can be increased. Also, belt-shaped shielding plates 30, 31
Since the shielding member is continuously supplied to the target spraying position A by the above, if the target 10 is positioned at the target spraying position A, the positions of the shielding plates 30 and 31 are not particularly taken into consideration.
The thermal spraying by the thermal spraying means 20 can be performed immediately, and the thermal spraying efficiency can be improved. Further, since the shielding member is constituted by the belt-shaped shielding plates 30, 31, there is no need to replace the shielding plates 30, 31 even if the size of the object 10 is large or small, and the versatility is excellent. Further, the moving direction of the shielding plates 30 and 31 and the moving direction of the moving object 11 of the object 10 are reversed, or the moving speed of the shielding plates 30 and 31 and the moving speed of the moving device 11 of the object 10 are changed. By making them relatively different, the spray metal or the like hardly adheres over the shielding plates 30 and 31 and the object 10.
