Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for manufacturing a control panel that is installed to control electrical equipment and the like and houses electrical appliances and control devices.
[0002]
[Prior art]
The control panel houses electric appliances and control devices in a housing, and is provided with a door for performing maintenance and inspection in the housing and operating internal devices. FIG. 5 shows an example of a conventional control panel. (For example, see Patent Document 1)
In FIG. 5, a mounting frame 12 is arranged on a housing 11 manufactured by a method of welding a steel plate or a method of assembling members, and a panel 13 for mounting an electrical component that has been drilled for mounting a plurality of components is mounted. Attach. Next, the electrical equipment mounting members 15a and 15b, the electrical equipment 6, the wiring member 16, and the wiring ducts 14a and 14b are mounted, and the electrical wiring is performed. Thereafter, a door is attached to the opening to complete the control panel.
[0003]
Generally, the height of the control panel has a dimension of about 2.0 m. Therefore, the work of mounting parts on the panel and wiring work are performed using a stepladder or the like. In addition, since the width of the control panel is generally about 0.7 m, a plurality of workers cannot enter the housing and work at the same time. Furthermore, if the housing 11 and the panel 13 are not prepared at the same time in the process, the manufacture of the control panel does not proceed.

[Problems to be solved by the invention]
As described above, in the conventional control panel, the casing 11 is manufactured in advance, and the assembling work of parts and the electric wiring work are performed in a state where the casing 11 is upright. For this reason, the worker has to work in a narrow environment with his or her arm and body inside the housing 11 and also has to work alone by himself throughout the work, which is poor in workability. In addition, the work of mounting and wiring components on the upper part of the housing 11 is performed at a high place using a stepladder or a step platform, which is dangerous. Further, the work below the housing 11 is performed while bending or waisting, which places a physical burden on the worker. Further, if the housing 11 and the panel 13 are not prepared at the same time in the process, the production of the control panel does not proceed, so that the production efficiency is poor.
[0006]
Next, when manufacturing the housing 11 by a method of welding steel materials, when the production amount is large, it is necessary to secure a lot of storage sites before the production is started. Must be implemented. Further, in the transportation process from the manufacturing factory of the housing 11 to the assembly work site, defects such as distortion and scratches may occur on the outer skin of the housing 11.
[0007]
Further, in the conventional control panel, the panel 13 for mounting control devices, electric appliances, wiring parts, and the like is manufactured by dividing it into a plurality of pieces in order to make the size and weight easy to mount. Therefore, there is a problem that the number of parts and the number of screwing points are large, and the number of assembling steps is increased.
[0008]
The present invention has been made in order to solve the above problems, and reduces the number of parts and the number of assembling steps, is safe and efficient, shortens the manufacturing process, and saves storage space before the production is started. It is an object of the present invention to provide a method of manufacturing a control panel with reduced management time.
[0009]
[Means for Solving the Problems]
According to the present invention, a panel for mounting an electric appliance is disposed in a vertical direction in a housing, an electric appliance is attached to the panel, wiring is performed, and the electric appliance is installed in a vertical direction of a surface of the panel on which the electric appliance is attached. A method of manufacturing a control panel for performing maintenance and inspection, wherein the panel is composed of one member for each direction in which maintenance and inspection is performed, and components for mounting electrical supplies on the panel outside the panel, After mounting articles, wiring ducts and wiring parts, and performing wiring work, the ceiling member and the bottom member of the housing are respectively attached from both sides in the long side direction of the panel, and the short side of the mounting surface of the panel for the electric article is installed. The housing is formed by attaching side members of the housing from both sides in the side direction.
[0010]
In addition, the method of manufacturing the control panel includes disposing the electrical component mounting surface of the panel facing upward, mounting the electrical component mounting component, the electrical component, a wiring duct, and a wiring component on the panel surface, The method includes a step of performing construction, a step of attaching the bottom member, a ceiling member, and a side member to the panel, and a step of attaching a door to an opening of a housing facing a mounting surface of the electric appliance.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example of an embodiment of a control panel manufacturing method according to the present invention. 2 and 3 are conceptual diagrams of a control panel manufacturing process, and FIG. 4 is a flowchart of a control panel manufacturing process.
In FIG. 1, a panel 1 for mounting an electric appliance is formed of an integral part with a size smaller than a width dimension and a vertical dimension of a housing. On the electric appliance mounting surface of the panel 1, electric appliance mounting components 5a and 5b, electric appliances 6, wiring ducts 7a, 7b and 7c, wiring components 8a and 8b, a ground bus 9 and the like are mounted, and electric wiring is performed. You. FIG. 2 shows a conceptual diagram of one method of manufacturing a control panel, which corresponds to step S1 shown in FIG. That is, the component mounting surface of the panel 1 is arranged upward, the mounting object is arranged on the surface of the panel 1, and electric wiring is performed. As shown in FIG. 2, holes 5c and 5d for attaching the attachment are provided on the attachment surface of the panel 1. The holes 5 c are elongated in the direction of the longer side of the surface of the panel 1, so that the device mounting interval can be adjusted according to the size of the electric appliance 6.
[0012]
FIG. 3 shows a conceptual diagram of the step S2 in FIG. That is, the ceiling member 2 and the bottom member 3 are attached to the panel 1 on which electric wiring has been performed from the long side of the panel 1, and the side members 4 are attached to the panel 1 from both sides of the panel 1.
Step S3 in FIG. 4 is a step of attaching the door 10 shown in FIG.
[0013]
In the present embodiment, since the panel 1 for mounting electrical appliances is integrally formed, the number of parts and the number of assembly steps can be reduced. In addition, since the panel 1 is arranged sideways like a work bench and assembly and electrical wiring work is performed outside the housing, multiple workers can work without the need to work at heights. Work efficiency is good. Furthermore, since the production can be started without preparing the housing and the panel 1 at the same time, the process can be shortened, and the labor for managing the parts storage area and the management can be reduced before the production is started.
[0014]
【The invention's effect】
As described above, according to the present invention, the number of parts and the number of assembly steps are reduced, the safety and work efficiency are improved, the production process is shortened, and the storage space before production is started and the control panel is reduced in labor. It is possible to provide a fabrication method.
