摘要： PURPOSE:To improve the welding accuracy and to reduce the welding cost by setting three-dimensional rectangular coordinates on material to be welded and classifying a weld line executing group capable of welding at one position of a welding robot and then, performing welding successively for every group. CONSTITUTION:A traveling carriage 12 on which the welding robot 11 capable of executing the articulated automatic position control is mounted is provided and positioners 13 to hold the material 15 to be welded freely turnably at both ends of a longitudinal axis are arranged. At this time, the positioners 13 are arranged so that the material 15 to be welded can be fixed for every 90 deg.. Three- dimensional axes X, Y and Z are set on a steel frame joint 15 and the Y axis is coincident with an axis of rotation of the positioners 13. A computer 14 classifies the stopping position of the carriage 12 and the torch position into groups for every turning angle of 0 deg., 90 deg., 180 deg. and 270 deg. of the positioners 13 and welding is performed successively for every group. Since a simple program can do, the welding accuracy is improved and the welding cost is reduced.

摘要： PURPOSE:To expand a working area and to improve productivity by maintaining a chair track of a closed loop in a trapezoid by four wheels and reversing a member which is carried in by adjusting an interval of the lower side wheels and adjusting the sag of the track by the normal rotation and the reverse rotation of the four wheels. CONSTITUTION:A closed-loop caterpillar 11 consisting of a chain is maintained in the trapezoid by the four wheels. The member 1 such as the long-size steel frame, etc., is carried from a chain conveyor 12 in the chain caterpillar 11 which is rotated normally. After the member 1 is taken in the sage 13 taking place on the chain caterpillar 11, the chain caterpillar 11 is stopped. At this time, the interval between the lower side two wheels is shortened. Next, the chain caterpillar 11 is rotated reversely and the member 1 is reversed in the sag 13. The chain caterpillar 11 is returned to the normal rotation and the member 2 after being reversed is carried out by a chain conveyor 16. The chucking time is shortened and the restriction of a reverse angle of the long-size member 1 is eliminated by this mechanism.

摘要： PROBLEM TO BE SOLVED: To make a prompt correspondence to an arbitrary roof slope by the use of a support metal fitting including in integral relation a base frame secured to a main frame, skeleton frame for wall material, and skeleton arms for a roof member. SOLUTION: A skeleton frame 6 projecting to the side of a wall material 1 is joined to a base frame 5 being bent into an L-shape secured to a main frame 4 by bolts, and s skeleton arm 7 projecting to the side of a roof material 2 from the midpoint of the skeleton arm 6 is joined thereto in order to form a support metal fitting 3, thereby allowing rain gutter joint members 8, 9 for the wall material and roof material each comprising a Z-bar to be joined in a relative posture to distal ends of the arms 6, 7. Thus, the wall material 1 and roof material 2 can be supported in a mutual function separation manner respectively in use of the joint members comprising general lightweight bars, and by selecting one of the relative posture of the skeleton arms 6, 7 and attachment posture of the rain gutter joint members 8, 9 relative to the arms 6, 7, a prompt and proper correspondence can be done to various kinds of slopes of the roof material 2.
