PURPOSE:To manufacture structures consisting of framelike members of desired sizes and shapes fully automatically by constituting a titled device of a conveying arm, a welding arm, a member supplying part, a controller, etc. CONSTITUTION:Desired quantities of members 200, 201- are contained in a member supply part 7, and a pusher 8 is operated by a transfer pawl 9 to press one end of the member 200 to a stopper 22. A conveying arm 2 is operated and the member 200 is gripped with a clamp 17 and is transferred. An X clamp 4 holds the member 200 in a direction X. The arm 2 grips and conveys the member 201 in a similar manner. a Y clamp 5 holds the member 201 in a direction Y. The arm 2 transfers the 202 in such a way that it is combined with the two members 200, 201 in the welding position point P. A welding arm 3 operates and the leading end of a welding torch 18 welds the weld line successively. The welded structure is released as the X clamp 4 is swiveled by 90 deg. in a direction R. The clamp 17 transfers the member 200 until part thereof arrives at the welding position point P, where the Y clamp 5 holds the same again, and the arm 3 welds the wled line again. The structure is obtained by the repetition of the above-mentioned operations. |
