Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a movable vehicle that can travel along a guide rail and is provided with an article support for supporting an article to be coated (C) by regulating its inclination with respect to a horizontal plane. The present invention relates to a coating transport facility in which an electric wire for setting a potential for an article to be coated, which is provided to be movable up and down and is supported by the article support tool, is wired between the mobile vehicle and the article support tool.

[Conventional technology]

The above-mentioned transporting equipment for coating is used when an article to be coated such as an automobile body is immersed in a coating tank for electrodeposition coating.

That is, the article support is lowered to immerse the article to be coated in the electrodeposition coating liquid. And the article to be coated is the (+) pole,
An electrodeposition coating film is formed by passing a direct current through the paint tank as the (-) pole. It should be noted that since the moving vehicle is usually at ground potential, it must be electrically insulated from the article to be coated.

Therefore, wiring for connecting the (+) side of the power supply device and the article to be coated is provided. If slack occurs in the wiring and gets caught on a mechanical structure during transportation, it may cause a failure or an accident. Therefore, this wiring must be properly held so that there is no slack. Moreover, the article support must be properly held both in the raised position and in the lowered position.

Therefore, for example, a wire winding mechanism may be provided to adjust the winding amount of the electric wire as the article supporter moves up and down, and hold the electric wire so as not to sag.

Further, the article to be coated is supported with its longitudinal direction oriented in the longitudinal direction of the moving vehicle.

[Problems to be solved by the device]

In the configuration in which the electric wire is wound as the article support is moved up and down as described above, an actuator for winding is required.

In addition, since the electric wire cannot be properly wound in a slack state, the electric wire is wound in a tensioned state. If tension is applied to the electric wire or the connecting portion between the electric wire and the electrode, mechanical damage may occur and cause a failure.

Further, in the structure in which the longitudinal direction of the article to be coated is supported in the front-rear direction of the moving vehicle, the pre-coating treatment liquid tank and the paint tank are long in the carrying direction, which is disadvantageous in that the carrying facility is long.

An object of the present invention is to eliminate the above drawbacks.

[Means for Solving the Problems]

In order to achieve this object, the characteristic structure of the transfer equipment for coating according to the present invention is that the article supports (B) are arranged side by side in the lateral direction of the moving vehicle in a front view and in the longitudinal direction of the moving vehicle in a side view. It is provided with four supporting rods (9) arranged with a space in between, and the front side left and right supporting rods (9) and the rear left and right supporting rods (9) are provided. It is configured to support the article (C) in the state in which the longitudinal direction of the article (C) is oriented in the lateral direction of the moving vehicle, and between the moving vehicle (V) and the article support (B), a bending and stretching type link. The mechanism (L) is provided, and the electric potential setting electric wire (11) is wired along the link member (7) of the link mechanism (L).

[Action]

The link mechanism bends and stretches as the article support moves up and down. Since the electric potential setting wire is wired along the link member of the link mechanism, the electric wire can be properly held regardless of whether the article support is in the raised position or the lowered position. Also, no tension is applied to the wires.

Further, since the article is supported with its longitudinal direction oriented in the lateral direction of the moving vehicle, the length of each processing liquid tank in the transport direction can be shortened.

[Effect of device]

Even if the article support is moved up and down, the electric wire can be properly held without using an actuator or the like for winding the electric wire. As a result, it is possible to provide highly reliable equipment having a simple structure and less risk of failure. Moreover, the conveying path can be shortened, which is advantageous in terms of equipment configuration.
