摘要： PROBLEM TO BE SOLVED: To provide a cable device for traveling apparatus, capable of being stored compactly when a traveling device returns to its initial position. SOLUTION: The guide means 42 of a cable 41 mounted between a traveling apparatus 10 and a stationary portion 30 is provided with a linear flame part 45 in the middle thereof, and the remaining part thereof is formed as bare cables 43, 44, 46 to meanderingly-store the frame part 45 in the stationary portion 30 as a traveling direction A. The guide means 42 is capable of being compactly stored in the stationary portion 30 with most thereof meandering positioned under the travel apparatus 10 at an initial position. The forward travel driving force of the traveling apparatus 10 permits the guide means 42 meandering stored in the stationary portion 30 to be pulled out automatically, and the reverse travel driving force of the traveling apparatus 10 permits the pulled-out guide means 42 to be meandering stored in the stationary portion 30 automatically.

摘要： PURPOSE:To improve the working rate by starting cutting after shifting a cutting torch to the same direction as the direction of movement of a cutting device in accordance with the detected partition distance of a material to be cut. CONSTITUTION:The plural materials to be cut 2 and 3 arranged in a cutting area 1 are simultaneously cut by the cutting device 10 mounting the plural cutting torches 14a and 14b. The cutting device 10 moves along a rail member 11, the end faces 2a and 3a in the breadthwise direction of the materials to be cut 2 and 3 arranged in the cutting area 1 are detected by detecting sensors 20a and 20b and the partition distance (d) of the materials to be cut 2 and 3 in the moving direction of the cutting device 10 is detected. The cutting of the materials to be cut is started after shifting the cutting torches 14a and 14b in the same direction as the movement of the cutting device 10 in accordance with the detected partition distance (d) of the materials to be cut 2 and 3. Thus the same graphics are respectively cut from the materials to be cut.

摘要： PURPOSE:To precisely meet a welding torch to perform automatic fillet welding even if the surface of a vertical plate fitted on a panel is inclined. CONSTITUTION:The inclination of the vertical plate V is obtained based on the installation data of a reference profile roller 6A to abut on the vertical plate V and measured values of a first distance sensor 7 and a second distance sensor 8 to measure the distance in the orthogonal direction to the traveling direction of a self-traveling type carriage 1 and the vertical plate V by a torch controller 4 and the distance to a fillet weld line X from the self-traveling type carriage 1 is operated to output a control signal to a torch driving device 5 to advance and retreat the welding torch 3. Consequently, the distance between the self-traveling carriage and the vertical plate surface is measured at three points to obtain the three-dimensional inclination of the vertical plate surface.

摘要： PURPOSE:To allow a moving body to automatically follow a traveling carriage by controlling the movement of the moving body based on a detection signal obtained by a detecting sensor of the tensile force of a tractive body and the moving direction of the traveling carriage. CONSTITUTION:At the time of welding a bar material 2 on a plate 1, when the traveling carriage 13 moves and the tensile force acts on a wire 27, the tensile force is transmitted to a block 26 for coupling and the tensile force is detected by a first strain gage 28. When the tensile force is above a reference, the tensile force is inputted as a detection signal from a second strain gage 29 and whether the direction of the tensile force is the front or the rear is judged based on the detection signal. Since the moving body 25 is moved so as to automatically fallow the traveling carriage 13 according to this judgement, a cable 22, etc., smoothly follow the traveling carriage 13 without working the excessive force on the cable 22, etc., and further, without twining round.

摘要： PURPOSE:To automatically and efficiently perform welding by detecting the distance with a work by noncontact-type distance sensors and profile-controlling a manipulator of a welding robot by a detected signal at the time of welding a corner part. CONSTITUTION:At the time of welding the corner part of a weld zone, the distance with the work is detected by the noncontact-type distance sensors 8a-8e. By the detected signal, the moving direction and the quantity of rotation of wheels 4 are deduced so that deviation between the working origin below the maximum operation of the manipulator 1b of the welding robot 1 and the operating central point of the manipulator 1b is diminished to zero. Based on this, the profile control is then executed. By this method, the welding can be automatically and efficiently performed.

摘要： PURPOSE:To improve efficiency of welding with a vertical thick plate joint which has low temp. toughness and for which specifications are severe by inserting a water-cooled copper strap having a projecting part and the other water-cooled copper strap into the groove of steel plates from one side. CONSTITUTION:The spacing between a backing strap 3 on the rear surface of the steel plates 1, 1 and the projecting part 6 of the water-cooled copper strap 4 in the groove 2 is subjected to root pass in a vertical attitude while the top end of a welding torch 12 is oscillated in the arrow direction shown in the figure from above. A shielding gas is blown from a blow-off port 9 in this stage and the strap 9 is moved upward along with progression of welding while said strap is cooled by the water in a cooling water pipe 11. The other water-cooled copper strap having no projecting part is used and the spacing between said strap and the root pass beads is similarly welded. Two-layer build-up electrogas arc welding is executed from one side under the welding conditions of the max. permissible heat input quantity for the plate 1 or below by the above-mentioned method with remarkably improved efficiency in a short period.

摘要： PURPOSE:To improve the molten metal fitness and bead appearance in toe part by forming a curved recess to the end face on the weld zone part of a water-cooled copper strap, keeping the notched angle of the toe part at 5-10 deg. and making the oscillating directions of the welding wire from a torch nozzle in the directions of a vertical plate, a base plate, a water-cooled strap and a vertical plate in this order. CONSTITUTION:A groove of about 45 deg. is formed to the end part of a vertical plate 2 to be welded to a base plate 1, and a water-cooled copper strap 6 is placed in the triangular weld zone formed by the base plate 1 and the vertical plate 2, thence welding is carried out. At this time, a curved recess 21 is formed to the end face on the weld zone 5 side of the strap 6, and the notched angle of the toe part A is kept at 5-10 deg.. Further, the oscillating directions of a wire are made in the directions of the plate 2, the plate 1, the strap 6 and the plate 2 in this order. Hence, the convection to the toe part A by the oscillating rotation of molten metal is made easy by the recess 21 and the notch.
