When by chassis A in the time that travelling of arrow a direction makes this chassis A (switch 4a) contact with butt plate E, produce signal transmitting to control device 25 from switch 4a.Utilize this war signal station car A to arrive the wheeled limit.And under this state, the fillet welding that welding torch B carries out the bight F of base plate C and upright plate D does not finish.
Therefore, after identification chassis A has arrived the wheeled limit, as shown in Fig. 6 (b), welding torch B is rotated as center using center of rotation H (rotation motor 15), and along the direction that partly radially approaches upright plate D using center of rotation H as center move linearly (advancing)., make welding torch B using center of rotation H as middle mind-set counterclockwise with angular speed Vr rotational angle r.Meanwhile, make welding torch B along the radius using center of rotation H as center forwards with speed Vf displacement f.
From the moment that produces signal from switch 4a, the driving of CD-ROM drive motor 3 stops, and chassis A makes Speed Reduction while utilizes inertia force to continue to travel.The reduced rate of the speed of chassis now, the moment that operating range can complete at welder measure, even if increase and also can significantly not change between the operating period.Therefore, after switch 4a produces signal, consider the reduced rate of the speed of chassis A, make welding torch B towards anticlockwise rotation with synchronize and control towards the movement in front, thus, irrelevant with the rotational angle of welding torch B, the distance of the distance bight F on the top of this welding torch B can be remained to constant, and will remain constant towards the speed of arrow a direction.
The rotational angle r of welding torch B, rectilinear movement are accompanied by the distance top and the bight F that sets the distance from the end of chassis A to center of rotation H, welding torch B apart from f and are set as unique.In addition, angular speed Vr when welding torch B rotates, rectilinear movement are estimated Vf and are accompanied by with thickness of slab, the material of base plate C and upright plate D and set speed of welding accordingly and be set as unique.
Therefore, by comprise the weld information of end (switch 4a) from the chassis A speed of welding to the information of the mechanical dimension of the distance of center of rotation H (rotation motor 15), when comprising across corner F and welding to 25 inputs of control device in advance, can calculate thus as rotational angle r, the angular speed Vr of the condition that welding torch B is moved, move linearly apart from f and translational velocity Vf.
And, utilizing when recognizing chassis A and arrived the wheeled limit from the signal of switch 4a, utilize the data of described result of calculation to control the driving of rotation motor 15, linear motor drive 22, can make thus welding torch B move as described above, and proceed welding for bight F until corner portion G.Like this, in the time approaching corner portion G for the fillet welding of bight F, welding torch B arrives near the end of travel direction of chassis A.
Continue as described above to utilize welding torch B to carry out the fillet welding for bight F, can weld reliably until the cross part of upright plate D and butt plate E is corner portion G.Wherein, if finish welding in this stage, produce arc crater at corner portion G.
Therefore, after chassis A arrives the wheeled limit, control the driving of rotation motor 15, linear motor drive 22, to welding torch B is returned by condition identical when welding torch B is moved.That is, so that welding torch B drives rotation motor 15 to the mode of rotating with rotational angle r, angular speed Vr clockwise, meanwhile, so that the mode that welding torch B retreats apart from f, translational velocity Vf with rectilinear movement drives linear motor drive 22.
And, when welding torch B returns, welding current is reduced, utilize this welding torch B to continue across corner F and weld, can carry out built-up welding to arc crater thus and carry out arc crater processing.
It should be noted that, in the time that the welding that makes target starts, when be placed with the chassis A shown in Fig. 3 on base plate C time, have the worry that cannot weld between the end (disposing the end of a side of switch 4b) at the rear of this chassis A and welding torch B.In this case, chassis A is stopped and making under the state of welding torch B running, as shown in Figure 5, so that welding torch B drives rotation motor 15 to the mode of rotating clockwise, and so that the mode that welding torch B advances drives linear motor drive 22, afterwards, by making welding torch B to counterclockwise rotating, and retreat while carry out welding, can eliminate the part that cannot weld.
And, after welding torch B is formed as the attitude shown in Fig. 3, can be by making chassis A proceed the fillet welding for bight F to arrow a direction running.
In described embodiment, welder is configured to using fillet welding as object, but is not necessarily defined in fillet welding, also can be using butt welding as object.In the case of the welder using butt welding as object, due to welding torch with respect to docking a pair of soldered material vertical configure, therefore, can remain substantially vertical welding torch support (not shown) with respect to soldered material and deal with by welding torch B is replaced by.
Form as described above welder, after chassis arrives the wheeled limit, can make welding torch rotate and forwards move, move and continue to utilize welding torch to weld by being accompanied by this, even if butt welding also can be welded by the weld seam to target in length range.
In addition, by making welding torch return, and proceed to reduce the welding of welding current after butt welding finishes, can carry out thus arc crater processing.
Next, utilizing Fig. 7 is that the situation that the bight of lower end of base plate and two upright plates and the corner portion being made up of them, terminal comprise bight and be positioned at the position that exceedes this corner portion describes to the weld seam of target.
It should be noted that, in the present embodiment, identical to the described welding shown in welding and Fig. 6 of corner portion G with the bight F (the first bight Fa) of the lower end of upright plate D (the first upright plate D) from base plate C, therefore description thereof is omitted.In addition, in the accompanying drawings, also description thereof is omitted to mark identical Reference numeral for the part identical with described Fig. 6.
In the present embodiment, multiple soldered materials comprise the base plate C of horizontal arrangement, with respect to the first upright upright plate D of this base plate C and from base plate C the second upright plate E upright and that intersect with respect to the first upright plate D, be formed with corner portion G at the first upright plate D with the part that the second upright plate E intersects.In addition, the first bight Fa that the weld seam of target is set as from being made up of the lower end of base plate C and the first upright plate D arrives through corner portion G the second bight Fb being made up of the lower end of base plate C and the second upright plate E., the weld seam of target comprises corner portion G interior and be set as both direction (first bight Fa～corner portion G～the second bight Fb).
First, chassis A and the first bight Fa are positioned in to base plate C above accordingly, welding torch B are remained to distance and the attitude of regulation with respect to the first bight Fa.And, operation setting is set travel direction and travel speed in the operation dial 10b of operation board 10, and operating selection switch 10c sets to be had the corner portion G being made up of the first upright plate D intersecting, the second upright plate E and base plate C and change the bond pattern welding direction during the weld seam incoming terminal of target.Afterwards, pushbutton switch 10a and utilize welding torch B to start the fillet welding for bight F makes chassis A to arrow a direction running (Fig. 7 (a)) simultaneously.
When utilize chassis A in the time that travelling of arrow a direction makes this chassis A (switch 4a) contact with the second upright plate E, produce signal transmitting to control device 25 from switch 4a.Utilize this signal to identify chassis A and arrived the wheeled limit.Afterwards, as shown in Fig. 6 (b), welding torch B is rotated as center using center of rotation H (rotation motor 15), and along the direction rectilinear movement (advancing) that partly radially approaches the first upright plate D using center of rotation H as center, can continue thus the fillet welding for the first bight Fa, weld until the cross part of the first upright plate D and the second upright plate E, i.e. corner portion G.
And, carrying out from the first bight Fa after the fillet welding of corner portion G, further make welding torch B counterclockwise rotate as middle mind-set using center of rotation H, and along partly radially moving linearly (retreating) away from the direction of the second upright plate E using center of rotation as center, continue thus to weld towards the second bight Fb from corner portion G.
After the switch 4a of end that is arranged at chassis A contacts with the second upright plate E, welding torch B arrives the rotational angle of the revolving member 16 till corner portion G, is set as unique apart from numerical value such as f along with conditions such as the distances top and the first bight Fa, the second bight Fb of the permission rotational angle of the distance of setting from the end of chassis A to center of rotation H, revolving member 16, welding torch B with the rotational angle for revolving member 16 corresponding to the fillet welding length of the second upright plate E from corner portion G, rectilinear movement.In addition, angular speed Vr when welding torch B rotates, rectilinear movement are estimated Vf and are set as unique along with setting speed of welding.
Therefore, by comprise to 25 inputs of control device in advance end (switch 4a) from chassis A to the information of the mechanical dimension of the distance of center of rotation H (rotation motor 15), comprise for the weld length of the second bight Fb, the weld information of speed of welding when the first bight Fa and the second bight Fb are welded, thus, can calculate as rotational angle r, the angular speed Vr of the condition that welding torch B is moved, rectilinear movement apart from f and translational velocity Vf.
And, utilizing when recognizing chassis A and arrived the wheeled limit from the signal of switch 4a, utilize the data of described result of calculation to control the driving of rotation motor 15, linear motor drive 22, can proceed thus the fillet welding from the first bight Fa to corner portion G.
Detect the rotational angle r of welding torch B by the rotation of rotation motor 15, in the time that identification welding torch B has arrived corner portion G, keep the rotation of rotation motor 15 while the rotation of the linear motor drive 22 that reverses, welding torch B can be remained to the distance of distance the second upright plate E constant, and to moving away from the direction of the first upright plate D.And in rotation motor 15 keeps process that same directional rotation and linear motor drive 22 reverse, welding torch B can move to the second bight Fb from corner portion G and carry out fillet welding.
After fillet welding moves to the second bight Fb from corner portion G, do not limit and will be set as which kind of degree for the weld length of the second bight Fb making as described above.That is, only depend on the rotation of the revolving member 16 based on rotation motor 15 for the fillet welding of the second bight Fb, irrelevant with travelling of chassis A.
