Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport facility, and more particularly to a transport facility having a plurality of overhead cranes and transport carriages such as extrusion profile coating facility and machining facility.

[0002]

2. Description of the Related Art Conventionally, an aluminum profile formed by an extrusion process is generally processed into a profile having excellent corrosion resistance and weather resistance through a surface treatment process. However, the conventional extruded profile coating equipment includes various equipment such as an anodizing treatment tank, an electrodeposition coating tank, and a baking room.
Since it is placed on the line, for example, if a lot of aluminum profile that requires a lot of processing time is ahead,
There is a problem that the processing time of the subsequent aluminum profile lot is restricted by the processing time of the preceding aluminum profile lot, and the waiting time of the subsequent aluminum profile lot increases. For example, suppose that it takes about 3 hours to process one lot of subsequent aluminum profiles and about 4 hours to process one lot of preceding aluminum profiles. Time) is about 1 hour.

On the other hand, in a machining facility having a plurality of overhead cranes, work is performed using these overhead cranes, but since these overhead cranes are designed to travel on the same traveling rail. , Unable to overtake other overhead cranes. As a result, there is an inconvenience that one overhead crane is forced to wait until the other overhead crane retracts from its working position.

Further, conventionally, in order to move the carrier truck in the orthogonal direction on the same plane, it was necessary to turn the rail at the cross point of the carrier rails. However, the turning device is installed at every cross point, which increases the cost.
