서로 대향하는 한 쌍의 측판(WA, WA)과, 측판(WA, WA) 사이에 복수 배치되는 각재(WB)를 가부착하여 이루어지는 가조립 사다리(KW)를 길이 방향으로 이동시키는 이송기구(2)와, 이동 라인 상에 배치된 용접부(3)와, 가조립 사다리(KW)의 각재(WB)를 용접 위치에서 보유지지하는 위치 결정 클램프 기구(5)와, 각재(WB)의 보유지지가 이루어진 상태에서 가조립 사다리(KW)을 고정하는 홀더 기구(6)를 구비하고, 용접부(3)에는, 하방의 측판(WAL)의 각구멍(WAh)에 일단부(WBe)를 삽입한 각재(WB)를 하방의 측판(WAL)에 대하여 그 내향면(WAi)측에서 또한 가조립 사다리(KW)의 표리 양측으로부터 용접하는 2조의 하측 용접 토치(31)와, 상방의 측판(WAU)의 각구멍(WAh)에 일단부(WBe)를 삽입한 각재(WB)를 상방의 측판(WAU)에 대하여 그 외향면(WAo)측으로부터 용접하는 1조의 상측 용접 토치(32)가 배치되어 있다.

    A ladder manufacturing device comprises: a transport mechanism (2) that moves a pair of side plates (WA, WA) opposed to each other and a preassembled ladder (KW) formed by point welding a plurality ofsquare materials (WB) disposed between the side plates (WA, WA) in the longitudinal direction; a welding portion (3) disposed on a moving path; a positioning clamping mechanism (5) that holds the square materials (WB) of the preassembled ladder (KW) at a welding position; and a pressing mechanism (6) that fixes the preassembled ladder (KW) in a state in which the holding of the square materials (WB) has been completed. The welding portion (3) is provided with two groups of lower-side welding guns (31) which weld the square material (WB) having one end portion (WBe) inserted into in a square hole (WAh) of a lower side plate (WAL) on the lower side plate (WAL) on the inward facing (WAi) side of the lower side plate (WAL) and both surface sides of the preassembled ladder (KW); and a group ofupper side-welding guns (32) which welds the square material (WB) having one end portion (WBe) inserted into in a square hole (WAh) of a upper side plate (WAU) on the upper side plate (WAU) from outward-facing (WAo)side of the upper side panel (WAU).
