[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tacking device for distributing and attaching a long material to a large plate in a hull block manufacturing process.

[0002]

2. Description of the Related Art In a long-end welding method which is one of the hull block manufacturing methods, a plurality of longe members are first welded to a large plate obtained by welding a plurality of veneers on one side.

[0003] In welding the long material to the large plate, it is necessary to perform tack welding before main welding. Japanese Patent Application Laid-Open No. Hei 5-319364, "Aggregate Automatic Distributing Apparatus" is known as the temporary welding automatic welding apparatus.

FIG. 13 is an overall view of the "automatic aggregate distributing apparatus" disclosed in the above-mentioned publication, in which the trolleys 15 and 16 move the trolleys 16 and 17, and the trolleys 16 and 17 move up and down. The shafts 18 and 19 are provided so as to be vertically movable. Below the elevating shafts 18 and 19, there are provided longitudinal positioning means 20 and 21 and a magnet 22 and 23 having a built-in pressing cylinder (not shown) therein. It is provided with welding devices 24 and 25.

[0005] When the NC traveling carriage 15 is moved to a predetermined distribution position of the large plate 2 by gripping the long material 10 by the long positioning means 20 and 21 from the long material storage area, the lifting shafts 18 and 19 are lowered. The magnets 22 and 23 are attracted to the large plate 2 to fix the large plate 2 and the longitudinal positioning means 20 and 21, and thereafter, the press-fitting of the long material 10 to the large plate 2 and the long material 10 Is corrected, and an arc is ignited on the temporary welding devices 24 and 25 to temporarily attach the long material 10 and the large plate 2.

[0006]

The invention disclosed in the above-mentioned publication can be evaluated as a direction for automating tack welding of a long material. However, the long material has a slight bend in the longitudinal direction. In addition, the large plate is not completely flat, and furthermore, because the longitudinal positioning means is hung down by the elevating shaft, a runout occurs at the lower portion, so that the longitudinal material is accurately positioned and temporarily positioned on the large plate. There is a problem that is not welded.

It is in an integrally locked state.

FIGS. 10 to 12 are side views showing the use of the present invention in the order of steps. FIG. 10 shows that one longitude material 10 has already been distributed on the large plate 2 and the next longitude material 10
FIG. 1 shows a state in which the filter 7 and the reference guide 11 are integrally taken to the long carriage 14.

In FIG. 11, the movement of the traveling vehicle 1 causes the fitter 7 and the reference guide 11 to move integrally above the long transporting vehicle 14 and to be located there.
By feeding 2 ', the filter 7 grips the long material 101 with the internal fluid cylinder 75, and
01 is received by the above-mentioned receiving bracket 74 and lifted.
At this time, the longitude members 101 to 103 are placed on the carrier 14 in a state of being offset from the end of the large plate 2 by a predetermined length (for example, 100 mm) in the longitudinal direction of the longitude member 10, and have the same input data as the value. In this case, the longi grip portion 115 is the longi material 1
01 is gripped.

In FIG. 12, the footer 7 having moved above the large plate 2 is gradually lowered onto the large plate 2 while being engaged with the reference guide 11 integrally. At that time, Longi 1
01 is dropped on the large plate 2 to a position where data is input at a predetermined pitch, and the distribution position of the long material 101 is determined.

At this time, the long grip 1 of the reference guide 11
15 descends onto the large plate 2 in a state where it is offset by a predetermined size as described above. Thereafter, the long material 101 is moved inward of the large plate 2 until the large plate end detection mechanism 116 detects the end position of the large plate 2 by the motor 111 (the other end detection mechanism of the reference guide 11 is the large plate 2). Move outward while pushing)
When the end of the large plate 2 is detected, it stops at the position, and the material distribution position of the long material 101 on the large plate 2 is determined.

Thereafter, the magnet 7 on the side surface of the filter 7 attracts the filter 7 to the reference guide 11 to perform positioning. When the position of the filter 7 is determined, the filter 7 is fixed on the large plate 2 by the bottom magnet 72.

Thereafter, the flange portions 10a and the web portions 10b of the long material 101 are pressed from above and from the sides by the fluid cylinders 73 and 75 in the fitter 7, and tack welding is performed by the welding torches 9, 9.

When the temporary welding at one place is completed, the magnet 71 holding the reference guide 11 of the filter 7 is demagnetized, the fluid cylinders 73 and 75 are released, and the trolley 4 shown in FIG. Using the reference guide 11 as a ruler, the filter 7 is moved, and the filter 7 is sucked to the reference guide 11 again. Then, the pressing cylinders 73 and 75 are operated to fix the longitude material 101 and perform temporary welding.

While the above description has been made with reference to the filter 7, the filter 6 also performs the same operation as the trolley 5.

Also, in FIGS.
Is described on the left side, but the present invention is not limited to this, and the carrier 14 may be arranged on the right side.

[0047]
