度増加および硬化などの原因となる。 A common method of coating the outer circumferential surface of a cylindrical object, such as a tube, with an ultraviolet curable resin and irradiating it with ultraviolet rays is to apply a high-pressure mercury lamp in parallel to the direction of travel of the tube and surrounding the tube. There is a method of curing the resin by passing the tube through a plurality of ultraviolet irradiation devices, but in this method, if the tubes are transported into the device intermittently, if the tubes are interrupted, The ultraviolet rays from the high-pressure mercury lamp leak outside through the opening of the apparatus, causing increased viscosity and hardening of the coating liquid in the coating apparatus near the entrance of the ultraviolet irradiation apparatus.

In the figure, 1, 6, 6' are high-pressure mercury lamps, 2, 7, 7' are reflectors, 3, 8, 8' are cylindrical objects to be treated, 4, 9, 9' are ultraviolet irradiation equipment, 5,
10 and 10' are openings of the ultraviolet irradiation device, and 11 is a light shielding plate.

もれの量は少ない。 In FIGS. 3 and 4, a plurality of arc-shaped high-pressure mercury lamps 6 each having a reflector 7 are arranged so as to surround the outer peripheral surface of a cylindrical object 8 to be processed. The cylindrical object 8 is uniformly irradiated while passing from left to right in FIG. In FIG. 4, since the irradiation direction of the high-pressure mercury lamp is perpendicular to the longitudinal direction of the cylindrical object, the amount of ultraviolet rays leaking from the entrance/exit opening is small.

理物に接触しても悪影響を及ぼすことはない。 5 and 6 are examples in which a reflector with a light-shielding plate is used, arranged so that the direction of ultraviolet rays emitted from a high-pressure mercury lamp forms an obtuse angle with the direction of travel of a cylindrical object. In FIG. 6, the direction of the ultraviolet rays emitted from the high-pressure mercury lamp makes an obtuse angle with the direction of travel of the cylindrical object, and since a reflector with a light shielding plate is used, after the cylindrical object 8' has passed, Also, there is almost no leakage of ultraviolet rays from the entrance opening, and normally,
There is almost no increase in the viscosity or hardening of the coating liquid placed near the inlet opening. Note that ultraviolet rays leaking from the exit opening can be prevented by installing a curtain or a brush-like device, if necessary. Note that since the coating applied to the cylindrical workpiece is already hardened when it passes through the outlet, there will be no adverse effect even if the brush or curtain comes into contact with the cylindrical workpiece.
