Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method of manufacturing a rectangular frame formed by using a channel material and mainly used for a wall for a house.
[0002]
[Prior art]
Conventionally, a rectangular frame that is formed using a long grooved material and a short grooved material and is used for residential walls, etc., is assembled by welding the long grooved material and the short grooved material on a horizontal plane. It is manufactured by doing. Therefore, there is a problem that a large space is required for assembly and welding.
[0003]
Further, although three or more groove-shaped short members are usually used, a device for positioning each of the groove-shaped short materials is required. Therefore, there is a problem that the number of devices corresponding to the number of short grooves is required, and the manufacturing cost increases.
[0004]
[Problems to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a method for producing a rectangular frame made of a channel material according to the first invention will be described with reference to FIGS. This frame is used as a wall of a house. In this manufacturing method, first, the long groove-shaped material 1 conveyed by the first conveyor 10 is horizontally held in a downward opening posture at a predetermined height position by an upper fixture 35 that can be moved up and down, and the upper groove. It is assumed to be the elongated material 1a. The upper groove length 1a is conveyed by the first conveyor 10 in the upward opening posture, and is reversed by the reversing mechanism 11 attached to the first conveyor 10 immediately before being held by the upper fixture 35. It is said. The front end of the upper groove-shaped long member 1a held by the upper fixture 35 is brought into contact with the upper stopper 37, whereby accurate positioning is performed.
[0008]
Next, the separate long grooved material 1 conveyed by the same first conveyor 10 is horizontally fixed immediately below the upper grooved long material 1a to form a lower grooved long material 1b. The tip of the lower groove-shaped long member 1b abuts on the lower stopper 38 and is positioned. The lower groove-shaped long member 1b is fixed on the first conveyor 10 by a fixing mechanism (not shown).
[0009]
Subsequently, the plurality of short grooves 2 conveyed by the second conveyor 20 provided in parallel with the first conveyor 10 are sequentially held by the mobile robot device 40 to be in a vertical state, and the upper groove length Between the material 1a and the lower groove-shaped long material 1b, it is magnetically attached to an electromagnetic cage 36 that can be moved up and down. The electromagnetic cage 36 is provided in the horizontal direction between the upper fixture 35 and the first conveyor 10, and firmly holds the short channel material 2 by its magnetic force.
[0010]
From this state, the grooved short member 2 is lowered Y together with the electromagnetic cage 36, and the upper grooved long member 1a is lowered Z together with the upper fixture 35, and the lower end of the grooved short member 2 is moved to the lower grooved long member 1b. After fitting into the groove, the upper end of the groove-shaped short material 2 is press-fitted into the groove of the upper groove-shaped long material 1a to form the temporary frame 5a. The reason for lowering the electromagnetic retainer 36 is to lower it while maintaining the vertical posture of the short grooved material 2 magnetically attached thereto. Thereby, the position shift of the groove-shaped short material 2 can be prevented reliably.
[0011]
Finally, after the temporary frame 5a is released from the electromagnetic holder 36, the temporary frame 5a is conveyed to the next process, and the upper groove-shaped long member 1a and the lower groove-shaped long member 1b and the groove shape are connected by the welding device 50 via the back bar electrode 53. The press fitting part with the short material 2 is welded. Positioning in this welding process is achieved by the horizontal stopper 51 with which the front end surface of the temporary frame 5a abuts and the vertical stopper 52 with which the front end upper surface abuts.
[0012]
Further, the vertical positioning of the long groove material 1 and the short groove material 2 is achieved by a positioning mechanism 60 provided in the welding apparatus 50. That is, the pin 61 of the positioning mechanism 60 is driven by the cylinder 62 into the hole 2a previously drilled in each short groove member 2, and the vertical position of the short groove member 2 is determined. After finishing the welding process and performing predetermined post-processing, a rectangular frame is completed.
[0013]
In the first invention, since the rectangular frame is assembled and welded on the vertical plane, a significant space saving can be achieved as compared with the case of performing on the horizontal plane. Further, since the plurality of short grooves 2 are magnetically fixed to the electromagnetic cage 36, a device for holding each short groove 2 is not required, leading to a reduction in manufacturing cost.
[0014]
An embodiment of a method for producing a rectangular frame made of a channel material according to the second invention will be described with reference to FIG. In this manufacturing method, first, the long channel-shaped material 1 conveyed by the first conveyor 10 is horizontally held in a downwardly opening posture at a predetermined height position by an upper fixture 85 that can be moved up and down. Thus, the upper groove-shaped long member 1a is obtained.
[0015]
Next, the separate long grooved material 1 conveyed by the same first conveyor 10 is horizontally fixed immediately below the upper grooved long material 1a to form a lower grooved long material 1b.
[0016]
Subsequently, the plurality of short grooved materials 2 conveyed by the second conveyor 20 were sequentially moved between the upper grooved long material 1a and the lower grooved long material 1b while being inclined by the mobile robot device 90. After (position P in FIG. 6), it is further rotated M to a vertical state (position Q in FIG. 6). By doing so, the upper end of the short groove-shaped material 2 is press-fitted into the groove of the upper groove-shaped long material 1a, and the lower end is press-fitted into the groove of the lower groove-shaped long material 1b.
[0017]
Finally, welding is sequentially performed by the welding device 50 from the portion where the press fitting is completed, and predetermined post-processing is performed to complete the manufacture of the rectangular frame.
[0018]
In the second invention as well, since the rectangular frame is assembled and welded on the vertical plane, significant space saving can be achieved. In addition, since the plurality of short groove-shaped members 2 are press-fitted between the upper groove-shaped long member 1a and the lower groove-shaped long member 1b by one robot device 90, and sequentially welded from the portions where the press-fitting is completed, Thus, the apparatus which hold | maintains each groove-shaped short material 2 is unnecessary. Therefore, the manufacturing cost can be greatly reduced.
[0019]
【The invention's effect】
In the first invention, since the rectangular frame is assembled and welded on the vertical plane, a significant space saving can be achieved as compared with the case of performing on the horizontal plane. Further, since the plurality of short grooves 2 are magnetized and fixed to the electromagnetic cage 36, an apparatus for holding each short groove 2 is not required, the manufacturing cost is reduced, and the productivity is improved. be able to.
[0020]
In the second invention as well, since the rectangular frame is assembled and welded on the vertical plane, significant space saving can be achieved. In addition, since the plurality of short groove-shaped members 2 are press-fitted between the upper groove-shaped long member 1a and the lower groove-shaped long member 1b by one robot device 90, and are sequentially welded from the portions where the press-fitting has been completed. The apparatus which hold | maintains each groove-shaped short material 2 is unnecessary. Therefore, manufacturing costs can be greatly reduced, and productivity can be improved.
