An apparatus and a method for treating a surface to definitely, and with a high quality, finish an object to be processed, are obtained. In the step of a first check, the numbers of objects (W) that are carried into areas (20A, 42A, 74A) where the steps of pre-cleaning, shot peening, and post-cleaning, are carried out, are counted and the conditions of the surfaces of the objects are detected. In the step of a second check, the numbers of objects (W) that are carried out of the areas are counted and the conditions of the surfaces of the objects are detected.

A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.

First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.
