Abstract

Only a bottle properly preliminarily heated is sterilized by hydrogen peroxide. Temperature inspection to the bottle is performed while travelling the bottle. During the inspection, a bottle of which temperature does not reach a predetermined temperature is removed and a bottle of which temperature reaches the predetermined temperature is continuously travelled, hydrogen peroxide condensed mist α is blown toward a mouth portion 1 a of the bottle by a spray tube 59 disposed at a predetermined position, and hot air is blown into the bottle from the nozzle while the nozzle 64 following the mouth portion of the bottle. According to such operation, only the bottle properly heated can be sterilized by the hydrogen peroxide, Thereafter, beverage fills the bottle, which is then sealed.

First claim

The invention claimed is:

1. A beverage filling apparatus comprising:
a molding section for molding a bottle from a heated preform through a blow molding process;
a sterilization section for sterilizing the bottle molded in the molding section with hydrogen peroxide mist or hydrogen peroxide gas;
a filling section for filling the bottle sterilized in the sterilization section with beverage and then sealing the bottle, the molding section, the sterilization section and the filling section being coupled continuously with each other;
bottle travelling means disposed for continuously travelling the bottle on a travelling path from the molding section to the filling section through the sterilization section, wherein the bottle travelling means is provided with wheels disposed in a row from the molding section toward the filling section;
grippers turning around the wheels while gripping bottle neck portion and transferring the bottle from an upstream side wheel to a downstream side wheel;
an inspection section for performing a predetermined inspection to the bottle molded in the molding section, the inspection section being disposed between the molding section and the sterilization section so as to be coupled therewith, the inspection section being provided with an inspection means configured to inspect an upper face of the bottle neck portion and the inspection section being further provided with discharging means for discharging, from the travelling path, the bottle being judged as existence of abnormality, the inspection means including a camera configured to receive light of a lamp reflected by the upper face of the bottle neck portion, an image of the upper surface of the bottle neck portion being picked up by the camera processed by an image processing device configured to discriminate existence of abnormality;
a chamber of the inspection section for covering a portion from the sterilization section to the filling section;
an air supply means coupled to the chamber of the inspection section for supplying cleaned air into the inspection section, in which the cleaned air streams toward the sterilization section,
wherein an atmosphere shutoff chamber is disposed between the chamber of the inspection section and a chamber of the sterilization section,
wherein partition walls are disposed, respectively between the chamber of the inspection section and the atmosphere shutoff chamber and between the atmosphere shutoff chamber and the chamber of the sterilization section,
wherein an air exhaust, as an air exhaust means, is coupled with the atmosphere shutoff chamber, and
wherein the air exhaust means is coupled to a portion adjacent to the atmosphere shutoff chamber in the chamber of the sterilization section, and the air exhaust means is connected to the air exhaust coupled with the atmosphere shutoff chamber, and thereby air with hydrogen peroxide mist or gas is exhausted out of the chamber by the air exhaust means.

2. The beverage filling apparatus according to claim 1 , wherein clean air is supplied into the chamber of the inspection section by air supply means, and air is discharged from the atmosphere shut off chamber by discharge means.

3. The beverage filling apparatus according to claim 2 , wherein an air nozzle forming an air curtain is disposed at a portion at which the chamber of the sterilization section contacts the atmosphere shutoff chamber.

4. The beverage filling apparatus according to claim 1 , air supply means have a heater for heat the supplying cleaned air into the inspection section.
