Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport system for a lightweight container which is easily affected by wind. More specifically, the transport route is maintained at a higher degree of cleanliness than other parts, and more This is to minimize the fixation of the transported object.

[0002]

2. Description of the Related Art Clean room systems are roughly divided into two types depending on the object to be cleaned. That is, an industrial clean room (ICR) whose main target is fine powder and a biological clean room (BCR) whose main target is microorganisms. Semiconductors in ICR,
Precision machines and the like are applied fields, whereas in BCR, medical care and medicine are applied fields. BCR is intended to create a sterile space in medical facilities, pharmaceutical facilities, etc., but its method is almost the same as ICR except for biohazard countermeasure equipment. A medical / pharmaceutical facility or the like requires a manufacturing / conveying system combined with such a BCR.

FIG. 8 is a perspective view of a transfer means in a conventional sterilization chamber, FIG. 9 is a perspective view of a conventional sterilizer, and FIG. 10 is a side view showing a penetrating portion between the sterilization chamber and the filling chamber. As shown in FIG. 8, a conveyor 3 is provided in the sterilization chamber 1 having the BCR structure, and the conveyor 3 conveys, for example, a lightweight container filled with chemicals or the like. A tunnel-shaped hood 5 made of a transparent resin material or the like is provided on the conveyor 3, and the hood 5 covers a transport space on the conveyor 3 to prevent large dust from adhering to the lightweight container. On the other hand, as shown in FIG.
A sterilizer 7 is installed in the sterilizer 7, and the sterilizer 7 covers the conveyance path with a large hood 9. A sterilizing lamp 11 is provided in the hood 9, and the sterilizing lamp 11 sterilizes the lightweight container conveyed into the hood 9. A plurality of exhaust fans 13 are attached to the hood 9, and the exhaust fan 13 exhausts the indoor air sucked from the inlet 9 a of the hood 9 to the outside of the hood 9 so that the germicidal lamp 11
This prevents the temperature from rising. That is, the exhaust fan 13
Is cooling the inside of the hood 9. As shown in FIG. 10, in the sterilization chamber 1, the transport system configured as described above has a through hole 17 formed in the partition wall 15.

In addition, in this transport structure, dust is generated from the conveyor 3 and dust rises from under the conveyor, which causes a problem that it is difficult to ensure cleanliness. Furthermore, in this transport structure, when the lightweight container falls down in the hood 5, the hood 5 must be removed, and maintenance takes time. On the other hand, in the conventional sterilizer 7, the indoor air sucked from the inlet 9a is exhausted to the outside of the hood 9 to prevent the temperature rise by the sterilization lamp 11, so that the inside of the sterilizer 7 is equivalent to the cleanliness of the inside of the sterilization chamber 1. There was a drawback that it was not possible to create a highly sterile environment. Further, since the intake port is limited to the inlet 9a, the wind speed at this portion is locally increased, which may cause the lightweight container to fall. Furthermore, the air pressure of the sterilization chamber 1 is equal to that of the filling chamber 1.
When the pressure is lower than 9 atmospheres, the air in the filling chamber 19 flows from the through hole 17 to the sterilization chamber 1, so that the lightweight container is
It was contaminated with 9 air and sometimes fell by the wind. The present invention has been made in view of the above circumstances, provides a lightweight container transfer system that can improve the cleaning of only the transfer path, and can prevent falls due to the influence of the wind at a minimum fixed position, and the initial cost.・
The objective is to reduce running costs and improve cleanliness, transport stability, and maintainability.
