Description

The present invention relates to a wiring work assisting device for a control panel using a projector.

Conventionally, a manufacturing work instruction method for projecting work instruction information in a manufacturing process on a processed surface of a manufacturing object using a projector (a device for projecting an image or a video on a large screen or the like) is known (Patent Document 1). ). As a result, the worker can correctly recognize the type and mounting method of the parts each time the parts are mounted, so that work errors can be reduced and work efficiency can be improved.

However, the above method indicates a method of mounting relatively large-shaped parts such as ICs, diodes, and chemical capacitors, and there is no description of wiring work of a control panel that is complicated and requires a lot of man-hours.
In the wiring work of these control panels, a large number of vinyl-insulated electric wires are used in consideration of the magnitude of the current, and the wiring is arranged so that the electric wires are not loaded in a limited space. There was a problem that it was very troublesome because it was necessary to wire it neatly.

Therefore, in view of the above problems, the present invention provides a wiring work assisting device for a control panel that quickly recognizes wiring points and does not make a mistake when performing wiring work for a control panel that is complicated and requires a lot of man-hours. Is a technical issue.

In order to solve the above problems, the wiring work assist device for the control panel of the present invention has a work table for wiring a control panel to which a plurality of control devices are attached, and between the plurality of control devices on the work table. A projector that directly projects the image of the wiring diagram on the housing of the control panel, a switch for the operator to switch the image of the wiring diagram, and information to be projected using the projector are recorded, controlled, and managed. It is a wiring work auxiliary device for the control panel equipped with a computer.
The computer displays an image of a wiring diagram for performing the wiring work by the projector at the time of the wiring work of the worker, and the worker presses the switch to perform the next wiring work. It is characterized by switching to the image of the wiring diagram of the above and controlling the interval of pressing the switch to be measured for each wiring operation.

According to the wiring work assisting device of the control panel of the present invention, since the wiring diagram is projected by using the projector, it is possible to give the wiring work instruction by the image.
Therefore, even in the wiring work of the control panel, which is complicated and requires a lot of man-hours, the wiring work can be performed according to the projected wiring diagram, so that the wiring work can be performed without making a mistake.
Further, since it is equipped with a computer that records, controls, and manages information projected on the projector, it is possible to handle different types of control panels.
In addition, in the projected image, only the wiring diagram in which the worker performs the wiring work at that time is displayed by the projector, and when the wiring work is completed, only the wiring diagram in which the wiring work is performed next is displayed. It is possible to switch to the image to be displayed, and the interval for switching the image (the interval between the switches pressed by the operator to switch the image) is measured for each wiring work. It becomes possible to measure the skill level.

It is a schematic front view (wiring is not shown) of the control panel. It is a schematic diagram at the time of wiring work of the control panel of this invention. It is a projector projection drawing. It is a schematic diagram of another embodiment.

A mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a schematic front view of the control panel (wiring is not shown), FIG. 2 is a schematic view of the control panel of the present invention during wiring work, and FIG. 3 is a projector projection drawing. 4 is a schematic diagram of another embodiment.

As shown in FIG. 1, the control panel 1 is a control panel base 2 in which a large number of various parts 3 such as a breaker 3a, a switch 3b, a relay 3c, and a transformer 3d are assembled (wiring is not shown).

FIG. 2 is a schematic diagram when the operator 100 performs the wiring work of the control panel.
First, various parts 3 such as a breaker 3a, a switch 3b, a relay 3c, and a transformer 3d are attached to the control panel base (housing) 2 based on a design drawing, and the front side of the control panel base 2 faces upward and the rear side faces downward. A projector 6 (a device that projects an image or a video on a large screen or the like) that projects a wiring diagram is installed above the work table 4.
The length of the legs 5 that support the workbench 4 can be adjusted according to the physique (height and the like) of the worker 100 and the size of the control panel base 2.
When the projector 6 is installed above the workbench 4, it does not interfere with the wiring work of the worker 100, and it is possible to prevent shadows of various parts 3 from being generated. However, it is not always necessary to install it above the workbench 4. For example, the projector 6 may be installed diagonally with respect to the workbench 4.
Further, the projector 6 is installed on the ground (floor surface), a wiring diagram is projected toward the ceiling, the projection drawing is reflected by a reflector (not shown) provided on the ceiling, and wiring is performed on the workbench 4. The figure may be projected.

The projector 6 may be suitable for the wiring work of the control panel 1 in terms of focal length, projection range, image correction function, and the like.
If the projection drawing from the projector 6 is out of focus due to the size and thickness of the control panel base 2 and each component 3, the automatic focus adjustment function of the projector 6 can be used, or the height of the legs 5 can be automatically adjusted. Manual adjustment is recommended.

The projected image information such as the wiring diagram projected from the projector 6 is controlled and stored by the personal computer 7 connected by wire or wirelessly.

The worker 100 can browse the wiring completion drawing from the screen of the personal computer 7 and browse the flow of the series of wiring work prior to the work (the wiring work can be prepared).
The personal computer 7 may be connected to the server 9 via the Internet 8, and the data may be stored in the server 9.

When changing the projection drawing when performing the next work, the personal computer 7 may be directly operated to instruct to project the next wiring drawing, but the switch 10 installed near the workbench 4 may be used. You may use it. It is also possible to measure the working speed (proficiency) by measuring the interval at which the switch 10 is pressed.

Next, a working method of wiring the control panel, which is a main part of the present invention, will be described in detail with reference to FIG.
In this example, wiring (connection) is performed from the component (3A) to another component (3B, 3C, 3D). Although the components (3A, 3B, 3C, 3D) are shown in FIG. 3 for the sake of explanation, the projector 6 does not necessarily have to project the components (3A, 3B, 3C, 3D). Only the wiring needs to be projected.

Here, three methods of FIG. 3 (a), FIG. 3 (b), and FIG. 3 (c) are illustrated as projection methods.

FIG. 3A displays only the wiring currently to be performed when wiring (connecting) a total of three wires (connections) from the component (3A) to the other components (3B, 3C, 3D). The wiring for which the wiring work has been completed is not displayed, and only the next wiring diagram is displayed.
Specifically, in FIGS. 3A and 3I, the component 3A is instructed to be wired to the component 3D, and the operator 100 performs wiring in this portion. After the wiring of the component 3A and the component 3D is completed, the operator 100 presses the switch 10 to project the next wiring diagram (FIGS. 3A and 3II). Then, in the next wiring diagram, the wiring that has already been completed is not displayed, and the wiring of the component 3A and the component 3C is instructed. After wiring to this portion, the operator 100 presses the switch 10 to project the next wiring diagram (FIGS. 3 (a) and 3 (III)). Then, in the next wiring diagram, the wiring that has already been completed is not displayed, and the wiring of the component 3A and the component 3B is instructed.

FIG. 3 (b) highlights (thickness, color) the wiring that is currently to be routed when wiring (connecting) a total of three wires (connections) from the component (3A) to the other components (3B, 3C, 3D). , Flashing, etc.). That is, the wiring work is completed and the wiring in the previous process is displayed at the same time.
Specifically, in FIGS. 3 (b) and 3 (I), the component 3A is emphasized to be wired to the component 3D, and the operator 100 performs wiring in this portion. After the wiring is completed, the operator 100 presses the switch 10 to project the next wiring diagram (FIGS. 3 (b) and (II)). Then, in the next wiring diagram, the wiring that has already been completed is usually displayed, and an emphasis instruction is given to wire the component 3A and the component 3C. The worker 100 performs wiring in this portion. After the wiring is completed, the operator 100 presses the switch 10 to project the next wiring diagram (FIGS. 3 (b) and (III)). Then, in the next wiring diagram, the wiring that has already been completed is usually displayed, and an emphasis instruction is given to wire the component 3A and the component 3B.

FIG. 3 (c) continues to project the wiring for which the wiring work has been completed. Since the screen change when switching the projection drawing is smaller than that in FIGS. 3A and 3B, it is possible to reduce the burden on the eyes and fatigue of the operator 100.

The embodiments shown in FIGS. 3 (a), 3 (b), and 3 (c) may be appropriately changed according to the preference of the worker 100. For example, in FIG. 3A, since the extra wiring is not displayed, it is possible to concentrate only on the target wiring. Since all the wiring is displayed in FIGS. 3 (b) and 3 (c), it is possible to easily imagine the rendering even during the wiring work.

It should be noted that the same projection method does not have to be consistently used when wiring one control panel 1, and the method of FIG. 3 (a) may be changed to the method of FIG. 3 (b) in the middle of the work.

Work progress information may be shown as part of the projection drawing. In this case, for example, in the control panel 1 that requires wiring at 1000 places in total, when the worker has finished wiring work at 600 places at present, "600/1000" or "60%" is displayed.
By displaying in this way, the worker 100 can clearly grasp his / her progress status numerically.
Further, a related person (factory manager or the like) can grasp the progress status of the work by looking at the progress status information of the control panel 1 in the process of creation without directly confirming with the worker 100.

Another embodiment will be described.
FIG. 4 shows the use of two projectors 6a and 6b. In FIG. 4, since the projectors 6a and 6b project the same location, it is possible to prevent the shadow of the worker 100 from being cast on the workbench 4.

In FIG. 4, the same location is projected by a plurality of projectors, but different projections may be performed. In this case, since a wide range that cannot be projected by one projector can be shared and projected by a plurality of projectors, it is suitable for wiring work of a large control panel.

Further, by connecting each projector to a personal computer and projecting different wiring diagrams to different areas, it is possible for a plurality of people to work at the same time.

The number of projectors may be set arbitrarily regardless of whether the number of projectors is two or two or more. Even if multiple projectors are installed, it is not necessary to use multiple projectors in the entire process, and only the necessary projectors need to be used according to the work content.

The operation of the wiring work method of the control panel 1 of the present invention will be described.
The worker 100 installs the base 2 of the control panel on the workbench 4 and starts the wiring work.
The worker 100 starts the personal computer 7, calls the data of the projection drawing of the control panel 1 to be worked on from the personal computer 7, and projects the data from the projector 6.
When the first wiring work is completed, the projection drawing from the projector 6 is switched for the next wiring by pressing the switch 10 (hand switch or foot switch), and the worker 100 re-wiring according to the projection drawing. The worker 100 repeats this work.
The management of the projection drawing is managed by the personal computer 7 connected to the projector 6, and the switch 10 projects a wiring diagram suitable for the work content.
In the projection drawing, not only the wiring diagram but also the work progress information of the worker can be known by displaying how far the worker 100 has proceeded with the work.

Since the personal computer 7 can access the server 9 via the Internet 8, it is installed not only at the time of wiring work of the control panel 1 at the factory but also at the site such as a building after the wiring work of the control panel 1 is completed. Even after that, if you bring the personal computer to the site, you can check whether the wiring is done correctly. In this case, the projector 6 does not necessarily have to be used.

Needless to say, the present invention is not limited to the above-described embodiment, and its configuration can be appropriately changed as long as it does not deviate from the scope of the invention. For example, the robot arm may perform the wiring work according to the projection drawing on behalf of the worker 100.

The working method of the control panel of the present invention is very useful because the wiring of the control panel can be wired without mistake.
