The joining line 3 may meander from side to side, and in this case conventionally the operator has controlled the welding device 6 such as a welding torch to the position along the joining line 3 by visual inspection. When manufacturing is carried out at high speed and the strip material 2 is fed quickly, such visual control by the operator is often insufficient and often causes the discharge of defective products, and also has the drawback of generally low production efficiency. It was hot.

転駆動されるものである。 A hollow circular rotary wheel 9 is rotatably supported on the base 10, and is rotated by a drive gear 11 via a gear attached to the outer periphery of the rotary wheel 9. The lever drive gear 11 is rotationally driven by a drive motor M, such as a step motor, which rotates in both left and right directions by a minute angle in response to input pulse information.

図ａに示されるように、その円形の検出用視野の
中心、つまりひとつの直径位置に端縁２１の線が
あらわれるように設定される。 The color detection plate 7 is a plate having a color that contrasts with the surface color of the strip material 2, for example, if the surface of the strip material 2 is white, it will be black.As shown in FIG. It is held between and supported by the edge of the strip material 2 to be joined. At this time, one edge 21 of the strip material 2 covers a part of the detection color plate 7, and the strip material 2 is arranged so as to cover a part of the detection color plate 7. However, the line image sensor 8 is the fourth
As shown in Figure a, the setting is such that the line of the edge 21 appears at the center of the circular detection field of view, that is, at one diameter position.

行するのである。 That is, the strip material 2 is vertically attached to the outside of the cable core 1, and the end edges 21 of the strip material 2 are overlapped to form an overlapping portion 22. The color plate 7 for position detection is inserted into this overlapping portion 22, and the strip material 2
advances while sliding against the color plate 7 for position detection.

るのである。 At this position, the light reflected from the joint part and entering the line image sensor 8 is equal in light from the white reflective part 2A on the strip material 2 side and from the black reflective part 7A on the position detection color plate 7 side. This allows it to be detected that the line of the edge 21 is at the center position.

ことになるわけである。 Now, if the joining line 3 of the strip material 2 moves due to the undulation or twisting of the cable, the edge 21 will appear in the detection field of view of the line image sensor 8 as shown in FIG. 4b or c. The line should appear shifted to the left or right. At this time, a command is issued from the line image sensor 8, and a servo control mechanism operates to rotate the rotary wheel 9 in a direction in which the light reflected from both sides of the position detection color plate 7 is equal, and the drive motor M is activated. As a result, the line image sensor 8 and the joining device 6 that moves integrally therewith return to the normal position shown in FIG. 4a, and the joining device 6 accurately aligns the joining line 3.
Therefore, the joining operation will be continued at this position.
