BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for assembling an H-shaped structure constructed by combining one web material and two flange materials arranged at both ends thereof.

[0002]

2. Description of the Related Art An H-shaped structure called a built-in H is formed by abutting both ends of a single web material by abutting the widthwise central portion of a flange material in a direction perpendicular thereto. The parts are assembled by fillet welding.

[0003]

Assembling of this type of H-shaped structure has heretofore been carried out mostly by hand, but this is a very laborious work. That is, since the recent H-shaped structure is required to have high dimensional accuracy, the web material and the two flange materials are aligned with each other, and those materials are supported and welded so as not to move in an unstable state. It requires extreme caution. Particularly, in the taper-shaped H-shaped structure, since the web material is a taper and the width of the web continuously changes in the longitudinal direction, it is more difficult to position and support.

Therefore, an object of the present invention is to make the assembling process of the H-shaped structure more automated than in the past, to improve the dimensional accuracy of the H-shaped structure and to shorten the time required for assembling.

[0010]

According to the present invention, as shown in FIG. 29A, for example, one web material (1) and two flange materials (2, 3) are placed horizontally on a table. When arranged side by side, the two flange members are vertically raised by the flange raising mechanism, and are oriented substantially perpendicular to the web member, as shown in FIG. 29 (B). Furthermore, the tip of the web material is lifted to about half the height of the flange material by the web tip positioning mechanism,
As shown in FIG. 29 as (C), it is supported horizontally.
That is, by this, the cross-sections of the leading end portions of the web material and the flange material are combined into an H shape. In that state, the abutting part of the web material and the flange material is slightly a little (for example, 50
If manually welded (about mm), the web material (1) and the two flange materials (2, 3) are temporarily attached at their tips to be integrated. The material that has been tacked is carried to the next main welding step by the carrying mechanism. In the main welding step, the material positioning mechanism sequentially positions and holds each part of the web material and the flange material, which are integrated and conveyed at a predetermined welding speed, in the H shape. Then, the abutting portions of the web material and the flange material are continuously welded by the continuous welding mechanism.

Therefore, most of the assembling operations requiring high accuracy are mechanically and automatically performed, so that highly accurate positioning is possible and positioning can be performed in a short time.

Further, in the third invention, the flange raising mechanism is configured to be movable in the width direction of the web material,
Moreover, a plurality of flange raising mechanisms are installed at different positions in the longitudinal direction of the web material. Therefore, even if the web material is tapered, the flange material can be abutted against the web material at each position. Further, the material positioning mechanism includes a support position moving means, and the support position of the web material is moved in the plate width direction of the web material as the web material moves in the longitudinal direction. Also, at any position in its longitudinal direction, it supports an appropriate position, and near the welding position of the web material and the flange material,
It can be held in a predetermined H shape. Further, since the continuous welding mechanism includes the welding position moving means for moving the welding position of the web material in the plate width direction of the web material in accordance with the movement of the web material in the longitudinal direction, even if the web material has a taper shape. It is possible to continuously weld the whole by moving the welding machine along the contact position between the web material and the flange material, that is, along the welding line inclined with respect to the material conveying direction.

In the second and fourth aspects of the invention, a plate joining mechanism is further provided, and the web members can be formed by joining together materials having short lengths. In particular, when a tape-shaped web material is cut out from a rectangular plate to be produced, a scrap material is more likely to be formed as the web material becomes larger, resulting in a large waste of material. Since a material having a small length is unlikely to form a scrap, a waste material caused by a scrap can be reduced by constructing a web material by joining materials having a short length.

[0069]

As described above, according to the present invention, as shown in FIG. 29A, for example, one web member (1) and two flange members (2, 3) are provided on the table. 2) are arranged side by side in a horizontal state, the two flange members are raised vertically by a flange raising mechanism, respectively.
As shown in FIG. 9 (B), it is oriented substantially perpendicular to the web material. Further, the front end portion of the web material is lifted up to about half the height of the flange material by the web front end positioning mechanism and horizontally supported as shown in FIG. 29 (C). That is, by this, the cross-sections of the leading end portions of the web material and the flange material are combined into an H shape. In that state, if the abutting portions of the web material and the flange material are welded by a small amount (for example, about 50 mm) by hand, the web material (1) and the two flange materials (2, 3) will have their tip portions. Is temporarily attached and becomes one. The material that has been tacked is carried to the next main welding step by the carrying mechanism. In the main welding step, the material positioning mechanism sequentially positions and holds each part of the web material and the flange material, which are integrated and conveyed at a predetermined welding speed, in the H shape. Then, the abutting portions of the web material and the flange material are continuously welded by the continuous welding mechanism. Therefore, most of the assembling operations that require high accuracy are mechanically and automatically performed, so that highly accurate positioning is possible and positioning can be performed in a short time.

In the third aspect of the invention, the flange raising mechanism is configured to be movable in the plate width direction of the web material,
Moreover, a plurality of flange raising mechanisms are installed at different positions in the longitudinal direction of the web material. Therefore, even if the web material is tapered, the flange material can be abutted against the web material at each position. Further, the material positioning mechanism includes a support position moving means, and the support position of the web material is moved in the plate width direction of the web material as the web material moves in the longitudinal direction. Also, at any position in its longitudinal direction, it supports an appropriate position, and near the welding position of the web material and the flange material,
It can be held in a predetermined H shape. Further, since the continuous welding mechanism includes the welding position moving means for moving the welding position of the web material in the plate width direction of the web material in accordance with the movement of the web material in the longitudinal direction, even if the web material has a taper shape. It is possible to continuously weld the whole by moving the welding machine along the contact position between the web material and the flange material, that is, along the welding line inclined with respect to the material conveying direction.

In the second and fourth aspects of the invention, a plate joining mechanism is further provided, and the web material can be formed by joining together materials having short lengths. In particular, when a tape-shaped web material is cut out from a rectangular plate to be produced, a scrap material is more likely to be formed as the web material becomes larger, resulting in a large waste of material. Since a material having a small length is unlikely to form a scrap, a waste material caused by a scrap can be reduced by constructing a web material by joining materials having a short length.
