The present invention relates to an air blowing apparatus that automatically recognizes the size of a member and removes the foreign matter so as to automatically move the spray, and more particularly, detects the size of the member entering the air blowing booth and fits the size of the member. The present invention relates to an air blowing apparatus capable of completely removing foreign matter remaining in a member by adjusting a working position.

In general, the abrasive blast cleaning process is a process of removing the shot balls and dust remaining on the surface of the pretreated member in the shot blasting process, which is performed before the paint process. As described above, the abrasive blast cleaning process is a surface treatment method of spraying abrasive particles at a high speed to remove black skin, green skin, dirt, and the like, and to form a rough surface called an anchor pattern to improve adhesion of paint. The purpose of blasting is to prevent paint defects that may be present after the completion of the painting work, to obtain good coating quality, and to maintain the long life of the material from corrosion. The member surface is covered with a deteriorated layer, an oxide layer, etc. by the material or processing method of the member, and dirt, such as fat, oil, moisture, rust, dust, etc. is attached. Adhesion with a coating material falls, and unevenness, swelling, and a crack of a coating film arise, and it causes a coating film to peel. Therefore, the oxide layer or the foreign matter on the surface of the member is removed through a blast cleaning process prior to the painting operation, and then the foreign matter remaining on the surface of the member is removed by spraying air on the surface of the member.

The construction and operation of a conventional air blowing apparatus for removing foreign matter remaining by spraying air on the member surface as described above will be described with reference to FIG. 1. 1 is a front configuration diagram of a conventional air blowing apparatus.
