  However, the installation of the louver requires the movable means and the control means, which complicates and enlarges the ultraviolet irradiation device, and the installation place is limited. In addition, while irradiating a sufficient amount of ultraviolet rays to the glove inserted into the sterilizing chamber, an ultraviolet guide path can be formed between the louvers such that ultraviolet rays can be prevented from leaking from the insertion port. Due to the small size, it is not easy to prevent not only the worker sterilizing the glove but also the surrounding workers from being irradiated with the ultraviolet rays.

  Therefore, the present invention has been made to solve the above-described problem, and is not only for workers who sterilize gloves, but also for workers around them while maintaining simplification and miniaturization of the device. It is another object of the present invention to provide a safe ultraviolet irradiation apparatus that is not irradiated with ultraviolet rays (or that irradiation of ultraviolet rays is suppressed as much as possible).

Irradiation light from the ultraviolet irradiation unit can be prevented from being directly radiated. Further, ultraviolet rays reflected from the inner wall of the sterilizing chamber and leaking from the insertion port can be shielded by a translucent ultraviolet light shielding plate covering the front and side surfaces above the insertion port. As described above, the ultraviolet device according to the present invention can protect the eyes of the worker who inserts the glove into the insertion port and the surrounding workers from the ultraviolet light without providing a movable louver, thereby simplifying and reducing the size of the device.

  Each of the insertion ports 130 is provided with a sleeve-shaped guide 140 extending from the opening edge thereof to the inside of the sterilization chamber housing 120, and a sensor 150 is provided inside the sleeve-shaped guide 140. I have. The sensor 150 detects a bar code or the like described in a detection object ID worn near the wrist wearing the glove G. In addition, on the upper part of the gantry 110, a translucent upper surface ultraviolet shielding plate 160 that covers the front above the pair of insertion ports 130, and a translucent side ultraviolet shielding plate 170 that covers the upper side surface of the pair of insertion ports 130 are provided. Is provided. A portion of the upper surface ultraviolet light shielding plate 160 that covers the middle part between the pair of insertion openings 130 projects more than the other part to form an overhang part 160a, and an eye of an operator who sterilizes gloves is exposed. Ultraviolet rays leaking from the insertion port 130 can be further shielded. The display unit 180 is provided between the upper surface ultraviolet light shielding plate 160 and the upper surface of the main body 100.

  The sterilization chamber housing 120 is formed of a light-shielding material that blocks ultraviolet light, such as a metal plate, and has a sterilization chamber 121 formed therein as shown in FIG. The sterilization chamber 121 is formed in a tapered shape that gradually becomes narrower from the insertion port 130 toward the inner bottom surface in accordance with the shape of a hand wearing gloves G inserted from each of the pair of insertion ports 130. . A plurality of ultraviolet irradiation lamps 123 as an ultraviolet irradiation unit are provided on an inner surface corresponding to the back side and the palm side of the inserted glove G among the inner side surfaces of the sterilization chamber 121. The ultraviolet irradiation lamp 123 is a mercury lamp that emits ultraviolet light having a wavelength of 185 to 280 nm, is installed in parallel with the upper surface of the sterilization chamber 121, and is bridged over substantially the entire width of the sterilization chamber 121. I have. The plurality of ultraviolet irradiation lamps 123 are parallel to each other. Further, a protective sheet 4 made of a member capable of transmitting ultraviolet light is attached so as to cover the entirety of the plurality of ultraviolet irradiation lamps 123. The protection sheet 124 prevents the fragments of the ultraviolet irradiation lamp 123 from scattering into the sterilization chamber 121 even if the ultraviolet irradiation lamp 123 is damaged. Although not shown in FIG. 2, a protection net may be provided on the front side of the protection sheet 124.

  The data of the description items of the detected object ID of the glove G read by the sensor 150 of the guide 140 of the insertion slot 130 is transmitted to the control unit 260, collated with the worker list stored in the worker identification unit 210, and At 10 it is identified whether the worker needs to be sterilized. If the worker needs to be sterilized, the control section 260 controls the display section 180 to display the worker name and to transmit an irradiation start signal from the ultraviolet irradiation lamp 123 to the irradiation determination section 125. When the ultraviolet irradiation from the ultraviolet irradiation lamp 123 is started, the control unit 260 starts the timer 240 and starts measuring the ultraviolet irradiation time. At that time, the sterilization state determination unit 220 starts monitoring the intensity and stability of the ultraviolet light from the ultraviolet irradiation lamp 123. The control unit 260 determines that the time measured by the timer 240 has reached a preset time (ultraviolet irradiation time), and that the glove G has a high intensity and stability from the ultraviolet irradiation lamp 123 within the ultraviolet irradiation time. When it is determined that is completely sterilized, the irradiation determination unit 125 controls the ultraviolet irradiation lamp 123 to transmit an irradiation stop signal. When the irradiation of the ultraviolet light from the ultraviolet irradiation lamp 123 is stopped, the control unit 260 displays the sterilization completion on the display unit 180 and transmits data such as the sterilization state from the communication unit 250 to the personal computer or the like.

  Meanwhile, when the stop time of the ultraviolet irradiation lamp 123 is long, the intensity, frequency, and the like of the ultraviolet light emitted from the re-lighted ultraviolet irradiation lamp 123 may become unstable.
