An efficient coating machines capable of hardening coating on works in a short hardening time with a small-sized hardening oven at reduced costs. The coating machine has a painting booth, a hardening oven and a work transfer device. The work transfer device has a rotary shaft provided at a center of the coating machine, and a plurality of hangers, each holding one piece of work and being turnable about the rotary shaft. The painting booth and the hardening oven are arranged around the rotary shaft into an arc-shaped configuration, respectively. The hardening oven has an arc-shaped work passage adapted to move the works. One piece of work is coated in the painting booth and continuously transferred to the work passage of the hardening oven while being held with each of the hangers and turned about the rotary shaft. In the work passage, the work is blown with hot air fed from a hot air generating device for hardening the coating on the work.
A coating machine for applying a coating to works, and heating the coating applied to the works for hardening, comprising: a painting booth for applying the coating to the works; a hardening oven for hardening the coating applied to the works; and a work transfer device, said work transfer device having a rotary shaft provided at a center of the coating machine, and a plurality of hangers, each holding one piece of the works and being turnable about said rotary shaft, said painting booth and said hardening oven being arranged around said rotary shaft into an arc-shaped configuration, respectively, said hardening oven having an arc-shaped work passage adapted to move the works, whereby the works are coated within said painting booth and continuously transferred in said work passage of said hardening oven while being held with said hangers and turned about said rotary shaft, and then, the works are blown with hot air fed from a hot air generating device for hardening the coating on the works.
