It is aimed to eliminate charges accumulated inside a wall structure of a resin vessel 2, which is sterilized by an electron beam irradiator 16, and an ionizer 134 disposed outside a filler 112 emits to the outer surface of the resin vessel 2 with negative ions having the same polarity as that of charges accumulated in the wall section of the resin vessel 2, while conveying the resin vessel 2 sterilized by the electron beam irradiator 16 to the filler 112, by which liquid fills the resin vessel 2. A filling nozzle 132 is connected to ground, and an ion flowing path is formed through a liquid column La filling the interior of the resin vessel 2 from the filling nozzle 132. The ions having the negative charges in a filling liquid L flow toward ground side of the ionizer 134, and on the other hand, ions having positive charges are attracted to the inner surface of the resin vessel 2 to thereby neutralize the charges remaining inside the wall structure of the resin vessel 2 with the ions having the positive charges.

To prevent electrical charging inside a resin material as well as a surface of a resin vessel at a time of sterilizing the resin vessel by being irradiated with electron beam, a bottle support unit is mounted to a lower end portion of a cylindrical rotating shaft rotatably supported by a rotating wheel. The bottle support unit includes a pair of griper members by which a mouth portion of a bottle is gripped. A ground electrode is disposed to be capable of being inserted into the interior of the resin vessel through a mouth portion thereof, and the interior of the resin vessel is irradiated with the electron beam in a state of the ground electrode being inserted into the resin vessel.

摘要:
Plastic containers fed by an article feeder housed in a shield chamber are sterilized by being irradiated with an electron beam that is radiated from an irradiation window of an electron beam irradiation unit which is coupled to an opening of the shield chamber. In a maintenance mode, an adjustment irradiation box is detachably mounted on the electron beam irradiation unit in covering relation to the irradiation window of the electron beam irradiation unit. The adjustment irradiation box houses therein an electron beam receiver for receiving the electron beam radiated from the irradiation window, a cooling mechanism for cooling the electron beam receiver, and an exhaust mechanism for discharging an atmosphere in the adjustment irradiation box.

In an irradiation region A in which an electron beam irradiator emits an electron beam through an irradiating surface 12a of the electron beam irradiator, areas B and D are formed in which one surface of a rectangular resin bottle 8 is in parallel with the irradiating surface 12a. Grippers 6 are arranged to an outer peripheral portion of a rotary body 14 in a circumferential direction thereof at an equal interval, and the resin bottles 8 are conveyed with neck portions 8a thereof being held. Rotating means (52, 58, 62) that rotate the grippers 6 with respect to the rotary body 14 and forward/rearward moving means (18, 50) that keeps constant a distance from the irradiating surface 12a of the electron beam irradiator are provided. In the electron beam irradiation region A, by rotating the gripper 6 by the rotating means, the resin bottle 8 is moved while maintaining one surface of the rectangular resin bottle 8 to be in parallel with the flat irradiating surface 12a.
摘要:
Even in a case where a spark is generated in an electron beam irradiation device 28, all the vessels 2 now being conveyed are surely sterilized by the irradiation with the electron beam. The electron beam is emitted by heating filaments 42 arranged in a vacuum chamber 40, and the vessels 2 are irradiated with the electron beam taken out into atmosphere through a window foil 48 of an irradiation window 46 formed to an irradiation section 44. The vessels 2 are conveyed in a state of being held by vessel holding portions 36A and 36B of a vessel conveying device 24 and pass in front of the irradiation window 46. Although the electron beam irradiation is temporarily interrupted when a spark is generated, a length of the irradiation window 46 in a vessel conveying direction X is made larger than a vessel conveying distance in an interruption time.
摘要:
An irradiation surface of an electron beam irradiation device 28 is directed toward a vessel 2 conveyed by a vessel conveying device 24 to thereby irradiate the vessel 2 with the electron beam to sterilize the vessel, an irradiation chamber 30 is provided so as to surround the irradiation surface of the electron beam irradiation device 28 and the vessel 2 subjected to the irradiation, a discharge chamber 32 is provided on an outlet side of the irradiation chamber 30, and dry-air supply means 80 for supplying a dried aseptic air is connected to the irradiation chamber 30. By removing moisture within the irradiation chamber 30 which is irradiated with the electron beam, the changing of nitrogen oxide to nitric acid is suppressed to thereby prevent metal portions from corroding.

An electron beam sterilizer has a bottle holder 28 provided with a rotation shaft 38, a neck gripper 70 mounted to a lower end of the rotation shaft 38, a rotating body 30 for rotating and moving the neck gripper 70 and a rotator revolver (segment gear 54, pinion gear 46, disc-shaped cam 66, etc.), and while conveying the resin bottle 2 in the state of being held, the resin bottle 2 is sterilized by irradiation with the electron beam through the irradiation window 19 of the electron beam irradiation device 18. The entire surface of the resin bottle 2 is completely sterilized by being rotated by the rotator during the movement in front of the irradiation window 19 and, thereafter, the rotator is inverted in position to return the neck gripper to thereby discharge the bottle.
