PURPOSE:To eliminate the need for the intermittent move of a fluorescent tube and improve its productivity by continuously moving the fluorescent tube and temporally stopping a desired metallic cap pin. CONSTITUTION:When a fluorescent tube 1 arrives at a trough section 4 and at the lower slope 41, a metallic pin 2 is guided by the lower slope 41 and a metallic pin 21 is fit in the bottom of the trough. The fluorescent tube 1 rotates by using the metallic cap pin 21 fit in the bottom of the trough 42 as an axial fulcrum and a backward travelling metallic pin 22 moves to the upper slope 43 when inverted. The fluorescent tube 1 slowly slides on the upper slope 43. The metallic cap pin 21 stops until the metallic cap pin 21 finishes being inverted at the specified position of the bottom of the trough. Specified welding work is performed with welding electrodes using this interval of time. |
