DETAILED DESCRIPTION OF THE INVENTION “Industrial field of application” The present invention is used, for example, when a long object such as a skin plate that is a member of a box column is groove-processed along the longitudinal direction.

“Prior Art” Conventionally, in the case of manufacturing a box column used as a column for construction, it is configured by combining four long plate-shaped members generally called a skin plate. At this time, in order to weld the abutting surfaces of the longitudinal edges of the skin plates to be joined to each other, and further to weld a plurality of reinforcing plates called diaphragms or rib plates to the skin plate so as to partition the inside of the column space. First, a predetermined groove is formed on the skin plate to be joined.

Specifically, it is as shown in FIG. This FIG. 6 shows a state in which the end portions of the groove-finished skin plate are assembled so as to vertically abut, and before welding.

FIG. 6 is a view showing a groove shape which is generally called a V-shaped groove. In the figure, reference numerals 3 and 4 indicate skin plates that have been groove processed. These skin plates
The three and four are arranged to vertically abut each other at their ends. The edges of the skin plates 3 and 4 that are brought into contact with each other are chamfered so that the chamfered surfaces 3a, 3b, 3c, 3d, 4a, 4b, 4c, 4d Are formed. Beveled faces 3a, 3b, 3c and Beveled faces 4a, 4
b and 4c are surfaces that are formed so as to be continuous, and the groove processed surfaces 3c and 4c are formed with deeper cuts than the groove processed surfaces 3a and 4a. This allows the skin plates 3,4
In the, along with the edge, a groove having a groove processed surface 3a, 4c and 4a, 4c having a constant groove shape, and a groove processed surface 3b, 4b in which the groove shape changes between them, Has been formed. Also, the cuts 3d formed on the skin plates 3 and 4,
4d is formed so as to be located at a position slightly separated from the end portions of the groove processed surfaces 3c, 4c. Then, the skin plates 3 and 4 are joined by injecting a welding additive into the groove-processed surfaces 3a, 3b, 3c, 3d, 4a, 4b, 4c and 4d.

Here, the reason why the groove shape is changed is to reinforce the portions that particularly require the bonding strength when, for example, a beam or the like is further provided on the skin plates 3 and 4.

Note that FIG. 6 describes an example of a V-shaped groove, but in a groove processing called a groove groove in which only one of the two skin plates arranged to be in contact with each other is groove-processed. Also, groove processing and welding similar to the above are performed.

[Problems to be solved by the invention] In this case, in the groove processing when the groove shape changes, the setting of the crater of the portable gas cutting machine is changed according to the groove shape which differs depending on the place. It cannot be continuously processed because it must be processed.

Also, when the groove is processed on the workpiece, the groove shape and its range are marked, and the worker sets the crater of the portable gas cutting machine to the groove condition, and the groove processed surface 3a, 3c, Groove processing is performed on 4a and 4c, and the groove shape changes 3
Since it was a process to finish b and 4b later,
At the same time as the work efficiency is poor, there is a defect that the groove shape varies depending on the degree of skill of the operator.

Based on the processing information received from the computer 40, the judging circuit 41 appropriately operates the traveling vehicle 6, the lateral moving bases 8,8,8,8, the vertical moving shaft 16, the rotary moving base 19, and the cutting torch 21. A command signal for the control signal is sent to each control circuit 42, 43, 44, 45, 46. Details of this command signal will be described together with the operation description of the groove processing device 5 described later.

The traveling vehicle control circuit 42, the lateral movement platform control circuit 43, the vertical movement axis control circuit 44, and the rotary movement platform control circuit 45 are judgment circuits.
According to the command signal received from 41, by controlling the positions of the traveling vehicle 6, the lateral moving bases 8,8,8,8, the vertical movement shaft 16, and the rotary moving base 19, respectively, they are fixed to the rotary moving base 19. The position of the cutting torch 21 is controlled. Also,
The gas output control circuit 46 controls the output of the cutting torch 21 according to the command signal received from the determination circuit 41.

In order to perform the groove processing by the groove processing device 5 configured as described above, first, the two running tracks 7 extending in parallel,
The workpieces 30 and 30 are fixedly arranged between the seven, and then the traveling vehicle 6 is arranged on the traveling tracks 7 and 7. Then, by operating the operation panel 50, the control device 60 is operated according to the processing information provided by the computer 40, and the traveling vehicle 6,
The horizontal moving table 8, 8, 8, 8, the vertical moving shaft 16 and the rotary moving table 19 are operated. As a result, the desired groove shape is processed on the work pieces 30, 30.

Next, the operation of the groove processing device 5 in this groove processing will be described in more detail with reference to FIG.

First, when the work vehicle operates the operation panel 50 and the operation of the groove processing device 5 is started, the processing information created in advance by the computer 40 is supplied to the determination circuit 41 in the control device 60 in STEP 1. It Then, when a machining start command is input from the operation panel 50 in STEP2, in STEP3, the determination circuit 41 performs each control for performing the groove machining on the workpieces 30, 30 in the groove shape according to the machining information. Circuit 42,43,44,4
A command signal is given to 5,46. The first command signal in this STEP3 is, for example, the end position of the section in which the first groove shape, which is the machining start position of the workpieces 30, 30, does not change, and the axis of the cutting torch 21 is the workpiece 30, Move the cutting torch 21 to a predetermined position that does not intersect with 30,
It is given to each control circuit 42, 43, 44, 45. Each control circuit 42,4
3,44,45 control the speeds and positions of the traveling vehicle 6, the lateral moving bases 8,8,8,8, the vertical moving shaft 16, and the rotary moving base 19 to move the cutting torch 21 to the processing start position. In addition, the gas output control circuit 46
, A command signal is sent to keep the cutting torch 21 inactive.

Then, when the cutting torch 21 is placed at the processing start position, the workpiece is cut at the end of the section where the groove shape does not change.
30,30 cuts are made. Next, when the cutting process is completed, that is, when the groove shape in the section in which the groove shape does not change is achieved, the process proceeds to STPE4 and fixed groove processing is performed. In this fixed groove machining, the cutting torch 21 is moved in parallel along the edges of the workpieces 30, 30 while the posture of the cutting torch 21 is maintained. Therefore, in this fixed groove machining, the command signal from the determination circuit 41 is mainly supplied to the traveling vehicle control circuit 42 and the gas output control circuit 46, and the other control circuits 4
A command signal for maintaining the attitude of the cutting torch 21 is supplied to 3,44,45. As a result, a groove whose groove shape is kept constant is processed.

Further, when the cutting torch 21 reaches the end position of the groove changing section, the process proceeds to STEP5, where the groove shape changing processing is performed in which the groove shape is changed within the groove changing section specified by the processing information. . That is, in the groove machining in the groove changing section, the cutting torch 21 has a groove shape that is machined after the groove changing section from the attitude in the section where the already processed groove shape is constant. The groove processing is performed while continuously changing until.

At this time, in order to obtain a smooth groove surface in the groove changing section, the determination circuit 41 determines that the traveling vehicle 6, the lateral moving platform 8,8,8,8,
Each of the control circuits 42, 4 is configured so that the vertical movement shaft 16 and the rotary moving base 19 simultaneously end the operation at the end point of the groove change section, that is, at the boundary position with the section where the subsequent groove shape is constant.
Supply command signals to 3,44,45.

Then, when the groove shape changing process in STEP 5 is completed, the cutting torch 21 is arranged at the end of the subsequent section in a posture capable of processing the groove shape of the section,
Moving to STEP6, fixed groove processing for the section will be implemented. Also in this fixed groove machining, similarly to the previous fixed groove machining, the cutting torch 21 is moved in parallel along the edges of the workpieces 30, 30 while the posture of the cutting torch 21 is maintained. Therefore, even in this fixed groove machining, the command signal from the determination circuit 41 is mainly supplied to the traveling vehicle control circuit 42 and the gas output control circuit 46, and the other control circuits 43, 44, 45 are disconnected. A command signal for maintaining the attitude of the torch 21 is supplied. As a result, the groove shape is kept constant and a groove having a shape different from that of the previous section is processed.

Then, when the fixed groove machining is completed, the process proceeds to STEP7, and the determination circuit 41 determines whether or not the machining is completed according to the content of the machining information. When finishing the machining, the workpiece 3 is moved while moving the cutting torch 21 in the vertical plane at the end position of the section, contrary to the cutting.
Cutting 0 and 30 ends the machining operation.

In STEP7, the case where the machining operation is not finished means that the position information of another groove change section adjacent to the section is further included in the processing information or there is no processing information of the adjacent groove change section. However, in the case where the groove shape contains other processing information at a position away from a certain section, in these cases, move to STEP 8 and make a determination according to the type of the processing information. Be seen.

Then, in the former case, the process returns to STEP 5 and the same groove shape changing process as described above is repeated, and in the latter case,
Similar to the case where the groove machining is finished in STEP 7, the machining opposite to the cutting is performed, and then the process returns to STEP 3 to repeat the cutting at a position apart from the end position of the section.

As described above, according to the processing apparatus of the present embodiment, even when there is a groove change section where the groove shape changes, not only a section where the groove shape is constant, but these sections are continuously opened. Pre-processing can be performed and a continuous smooth groove surface can be obtained.

Further, according to the processing apparatus according to the present embodiment, a plurality of cutting torches 21 and a traveling vehicle 6 that can move these in a multi-axis direction, a plurality of lateral moving platforms 8,8,8,8, a vertical moving shaft 16 and Rotary transfer table 19
Since it is equipped with, it is possible to simultaneously process two sides of the workpiece. As a result, in particular, it is possible to process two sides at the same time without deforming the workpiece of the long object during the groove processing. Further, since all the groove processing is controlled by the control device, the operator only needs to operate the operation panel, and the work efficiency can be improved.
