Abstract:
1. 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; a hot air generating device for feeding hot air to the works transferred in said hardening oven; and a work transfer device, wherein said hardening oven includes an outside air feeding wall and an inside air feeding wall, each being tubular and having an are-shaped cross-section, to define an arc-shaped work passage to move the works therebetween, said hardening oven further includes a plurality of screen plates which are respectively provided in an interior of each of said outside air feeding wall and said inside air feeding wall for locally screening passages for hot air fed from said hot air generating device, said work transfer device has a rotary shaft provided at a center of the coating machine, and a plurality of hangers, each holding at least one piece of the works and being turnable about said rotary shaft, and said painting booth and said hardening oven are arranged around said rotary shaft into an arc-shaped configuration, respectively, whereby the works are coated within said painting booth and continuously transferred in said arc-shaped 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 said hot air generating device for hardening the coating on the works.
