Place the rail parallel to the welding line (of course, you can also place the welding object so that the welding line is parallel to the rail), and while running the welding machine on the rail, weld the welding line. It is known to weld automatically. In this case, welding is easy if the welding line is a straight line, and it is sufficient to simply place a straight rail parallel to the welding line and weld the welding line while running the welding machine truck on the rail. The welding speed is equal to the cart speed, and in order to set the welding speed to a desired value, the cart speed may be set to the desired value. On the other hand, if the weld line is bent, the situation becomes complicated. In other words, if a straight rail is placed almost parallel to the bent welding line and the welding machine cart is placed on the rail and welded while traveling, the distance between the welding machine and the welding line changes as it travels, so it is possible to move forward and backward from the welding machine. It is necessary to take measures such as taking out an arm, attaching a welding torch to the tip of the arm, and moving the arm back and forth in accordance with the above-mentioned interval variation so that the tip of the torch always aims at the welding line. Various means have been developed for automatic torch tracing.

However, even if the torch tip is controlled so that it always aims at the weld line, the problem of welding speed remains unsolved. In other words, the welding line is the straight rail and θi (i= 1 , 2
...), the length ΔL of the weld line welded while traveling on a certain section Δ l of the rail is ΔL = Δ l /cosθi, and the speed of the bogie on the rail is kept constant. Since V, that is, Δl /Δt (where Δt is the time for traveling Δl ), the welding speed U, that is, ΔL/Δt, changes according to 1/cosθi. The rail is straight,
If the welding line is a curve, the welding speed changes continuously.

To explain the operation, the material to be welded is placed on the base 40 so that the weld line A is parallel to the rail 12, but since the rail is straight and the weld line is doglegged, it is not completely parallel. The guide arm is moved up and down appropriately so that the roller 32 hits the back side of the upright plate 30 (with the torch side as the front side), and the torch 24 welds the weld line A created by the contact area between the surface of the upright plate 30 and the surface of the bottom plate 28.
Try to aim for The aiming angle θ of the torch with respect to the welding line A is adjusted by moving the torch along the arcuate plate 22a of the support frame 22. The roller 32 is constantly pressed against the upright plate 30 by a spring 38, and the position of the roller 32 with respect to the support frame 22 is detected by a potentiometer 36, and the output of this potentiometer becomes a signal for controlling the movement of the guide arm 16. Initially, the position of the guide arm 16 is set so that the potentiometer output is zero.

When the presetting is completed, the cart 10 is moved and gas arc welding is started. As the truck 10 travels, the distance between the upright plate 30 and the rail 12 changes, which causes the roller 32 to move back and forth and the output of the potentiometer 36 to change. For example, when the roller 32 moves toward the rail 12, the output becomes a negative value according to the amount of movement, and the guide arm 16 moves backward until the output becomes 0, and the roller 32 moves away from the rail 12. Then, the output of the potentiometer becomes a positive value corresponding to the amount of movement thereof, so that the guide arm 16 advances until the output becomes zero. Thus roll 3
The guide arm 16 is moved forward and backward by the output of the potentiometer generated by the lateral movement of the torch 24, and the torch 24 is automatically controlled so as to always aim at the welding line A and perform welding.

When the trolley 10 travels, the rollers 32
The encoder 34 contacts and rolls on the vertical plate, thereby causing the encoder 34 to generate pulses. This pulse is generated every predetermined rotation angle of the roller 32, and the pulse period is equal to the rotation speed of the roller 32, and the number of pulses is equal to the rotation speed of the roller 32.
Indicates the number of rotations. The rotation speed of the roller 32 takes a constant value proportional to the speed of the truck 10 when the weld line A is parallel to the rail 12, and changes depending on the angle θi when the weld line A is oblique to the rail 12, as described above. The welding speed can be detected by the speed of the roller 32, which is desired to be constant, so in the present invention, the pulse period of the encoder 34 is detected and the speed of the trolley 10 is changed so that this becomes constant. Thus, according to the present invention, by attaching a potentiometer for detecting the lateral movement of the control roller 32 and an encoder for detecting the roller rotation speed, the weld line is not simply parallel to the rail 12 but is bent. Automatic fillet welding and constant welding speed control of objects to be welded can be easily performed.
Next, details of each part will be shown using specific examples.

is a terminal connected to the encoder 34 and receiving pulse output. 70 is a photocoupler comprising two pairs of light emitting diodes and phototransistors, which receives pulses from the encoder and outputs the signals shown in Fig. 7 at output terminals a and b.
Rectangular waves a and b (indicated by the same symbols) shown in (1) and (4) are generated. FF1 to FF4 are flip-flops, connected as shown in the figure, and the Q output terminals are connected to the terminals shown in Fig. 7 (2), (3),
As shown in (5) and (6), pulses indicating the leading and trailing edges of rectangular waves a and b are generated. These pulses are collected by an OR gate OR to produce pulse g shown in FIG. 7(7). This pulse g has a frequency of 4 rectangular waves a and b.
It has been doubled. That is, this FIG. 5 shows a frequency multiplier circuit. The welding speed is extremely slow compared to the motor rotation speed, etc., and therefore the frequency of the signal output from the encoder is also extremely low, making it difficult to use as it is, so this circuit increases the frequency.

1. A truck that runs on a rail almost parallel to the weld line made by the vertical plate and the bottom plate, a guide arm that protrudes laterally from the truck and can move up and down and move forward and backward, and a guide arm that is attached to the tip of the guide arm. , a welding torch that aims at the welding line, a roller that rolls in contact with the back side of the standing plate opposite to the welding torch, an encoder that generates a pulse according to the rotation of the roller, and detects the forward and backward movement of the roller. a detector; a traverse motor that advances and retreats the guide arm based on the output of the detector so that the welding torch always aims at the welding line; and a traverse motor that adjusts the traveling speed of the trolley based on the output of the encoder so that the welding speed is at a predetermined value. 1. An automatic welding machine for fillet welding, characterized in that it has a running motor that makes the welding speed equal to .
