ず、装置全体が長大化する欠点がある。Problems that the invention aims to solve In the conventional device described above, only a small portion of the ultraviolet light emitted from the ultraviolet lamp of the irradiation device is used because the optical fiber that is the object to be irradiated is thin, and most of the ultraviolet light is used. Since the particles scatter, the irradiation efficiency is poor and the irradiation time for curing the photosensitive coating material becomes long, making it impossible to increase the transport speed of the optical fiber. In order to increase the transport speed, it is necessary to increase the number of irradiation instruments, which has the drawback of increasing the length of the entire apparatus.

る。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks, and in order to efficiently utilize the ultraviolet rays from the lamps, a plurality of ultraviolet lamp irradiation devices each having a shutter are placed around the passing position of the object to be irradiated. The object-side surface of the shutter is a reflective surface, and the shutter is configured to open and close in a substantially circumferential manner around the position where the object passes.

され、同一方向に開閉動作をさせる機構とする。 In the figure, reference numeral 1 denotes an irradiation device, and the irradiation device is composed of a reflecting plate 2, an ultraviolet lamp 3, and a shutter 4 whose surface corresponding to the object to be irradiated is a reflective surface. 5 is a quartz tube through which an object to be irradiated, such as an optical fiber coated with a photosensitive resin coating material, passes. In FIG. 1, the shutter 4 is in a closed state, and ultraviolet rays are blocked. In FIG. 2, the shutter 4 is in an open state, and the shutter 4 is stopped between adjacent irradiation devices. The ultraviolet rays from the ultraviolet lamp 3 pass through the quartz tube 5 and are irradiated onto the optical fiber, and the ultraviolet rays leaving the optical fiber are reflected by the surface of the shutter 4 facing the opposite side, and the reflected light is irradiated onto the optical fiber. The shutters of each irradiation device are arranged approximately in a circumferential manner around the passing position of the object to be irradiated, and are configured to open and close in the same direction.

Ultraviolet rays that do not hit the irradiated object are reflected by the reflective surface of the shutter, and more of the UV rays hit the irradiated object, resulting in high irradiation efficiency and even when the irradiated object is transported at high speed, it does not damage the photosensitive coating material or the like. The paint can be cured in a short time, and the installation space can be reduced by arranging a plurality of irradiation devices facing each other in a substantially circumferential manner around the path of the object to be irradiated.
