目的は、相互干渉を招来することなくブースの小型化を
図ることができ、しかも、原動装置の小型化も図ること
ができるようにする点にある。However, the above conventional technique has the following drawbacks. That is,
When moving along an arcuate transfer path inside the booth, the objects to be coated in the transfer direction move closer to each other than when moving along a straight path outside the booth, and the degree of approach is the curvature of the arcuate transfer path. When the curvature of the arcuate transport path is too large, mutual interference occurs such that front and rear objects to be coated come into contact with each other and processing of the objects to be coated is hindered. On the other hand, in coating equipment, the curvature of the arc-shaped transfer path in the booth affects the size of the booth, and in order to reduce the size of the booth, the curvature of the arc-shaped transfer path should be increased as much as possible. Is essential. However, there is a limit to the minimum bending radius of the chain conveyor, and it is often larger than the minimum radius sufficient to prevent the mutual interference. Since the minimum radius of the route is restricted to be equal to or larger than the minimum bending radius of the chain conveyor, the booth tends to be unduly large. Moreover, in the chain conveyor, the smaller the bending radius, the larger the tension of the drive chain and the greater the drive resistance, which requires a large capacity drive device for moving the drive chain. In the case of the above-mentioned conventional technique in which an arcuate transport path exists in the middle of the chain conveyor, the cost of the prime mover is high. An object of the present invention is to make it possible to reduce the size of the booth without causing mutual interference, and also to reduce the size of the prime mover.
