This welding robot device 4 attaches anchor hardware S with ferrules F to all anchor hardware attachment positions on the plate P.

When the plate P to which the anchor hardware S is attached further rotates to position D, the ferrule removal and product unloading device 6 repeatedly destroys and blows away the ferrules F for each anchor hardware S to remove all the ferrules F, and then removes the plate. Fixing device 1
2 and 13 release the clamp on the plate P.
Then, the ferrule removing and product unloading device 6 unloads the product W onto the overturning table 63 of the overturning device 62 . Therefore, the product W is carried out from the turntable 1.

When the product W is fed into the overturning device 62, the overturning table 63 of the device 62 rotates laterally by 90 degrees.
The product W is placed upside down on the conveyor 65 of the coating device 64, and while being moved by the conveyor 65, it is further coated by the coating mechanism 66 and dried, and the coating finish is completed on the exit side of the conveyor. The finished product W is transferred to the product stacking device 6
8 is loaded onto the cart 69.

Since each of the above-mentioned operations is performed simultaneously and automatically on one turntable 1 while the turntable 1 is stopped, the manufacturing work after preparation for manufacturing can be performed efficiently.
