の充填機である．Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an aseptic filling machine for aseptically filling liquid contents such as food, drink, medical drugs, etc. in a linear or rotary filling machine. ．． (Prior technology) Conventionally, when filling work is performed in a clean or dust-free environment, a filling machine or a filling section is installed in a sterile room. In a sterile room, HEP A (High Efficiency) is generally used.
Sterile air is passed through a filtration device with a filter as the final stage, and the resulting sterile air is blown into a clean room through a large-diameter pipe, and the room is sterilized by maintaining positive pressure with sterile air. In order to prevent contamination of the contents by microorganisms, etc., the sterilization of the sterile room is maintained, and in order to prevent contamination, the sterile air blowing line is sterilized, including the filling nozzle and the filling pipe. This is carried out along with sterilization of roads, aisles for contents, etc. Conventionally, the sterilization of the 1!2M air blowout line has been carried out separately from the sterilization of the filling line of the filling machine, the passage through which the contents pass, etc. Sterilization of sterile air outlet pipes is generally performed in an open system because the pipes have a large diameter. Therefore, IR cannot be sterilized using hot water or superheated steam (above Zoo℃).
The iJ method uses low-pressure steam (maximum 100°C), heated gas, a mixture of heated air and steam, or a mixture of heated air and chemical sterilizers to sterilize. When hot water or superheated steam is used, it is possible to sterilize deep layers, but these methods only sterilize the surface layer or do not apply enough heat, resulting in insufficient sterilization. There is. Sterilization is also carried out using disinfectants alone, but in this case, only the surface layer is sterilized, and the disadvantage is that it cannot sterilize the bacteria beneath the foreign object. There are also problems with cleaning and sterilizing the passages through which the contents of the filling pipes and the contents of the filling machine pass, such as the mechanism being structurally complex and requiring a lot of labor. A liquid filling device 'I1 (Japanese Unexamined Patent Application Publication No. 1983-1993) was developed to easily perform cleaning and iRrII.
-67201) has been disclosed. this! A2l
! In this case, a cap is attached to a nozzle that communicates with a drain pipe at the opening end of the filling nozzle using a combination of an up-and-down mechanism and a rotating mechanism, so that it can be automatically attached and detached, and during sterilization, the filling nozzle cap is fitted and used to remove F:II agent, steam, etc. The inside of the passage for the contents is sterilized, and when filling, the nozzle cap is removed and lowered along with the drain pipe to ensure that there is no problem with filling. However, with this method, the drain pipe enters and exits the filling section in the sterile chamber, and there are many pipes, mechanical parts, parts with sliding parts, moving parts, etc. remaining in the S-sterilization chamber, resulting in the risk of contamination. , and the filling head is working.
In some cases, the mechanism becomes complicated, which is not desirable. Furthermore, the sterile air outlet line must be sterilized separately, which requires more labor. (Problems to be Solved by the Invention) In the conventional aseptic filling method, the sterilization of the air supply pipe in the sterile room and the cleaning and sterilization of the contents filling pipe of the filling machine, the passage through which the contents pass, etc. are performed by separate mechanisms. Since this was done separately, the mechanism is complex and requires a lot of labor. In addition, because sterilization methods are used that use low-pressure steam, heated gas, heated air and steam, heated air and chemical sterilizers, or sterilizers alone, sterilization is performed only on the surface layer. or the sterilization of the water pool is insufficient.
There are many problems in ensuring sterility, such as the inability to sterilize bacteria under foreign substances. In addition, there is a high risk of contamination in maintaining the cleanliness of a sterile room, and the 1-hour contamination prevention mechanism is not necessarily sufficient, and improvements are desired. The present invention has been made in view of the above circumstances, and an object of the present invention is to localize the filling part to facilitate maintaining positive pressure with sterile air, improve the contamination prevention effect, and improve the supply of sterile air. By using the conduit as part of the recovery conduit for cleaning liquid or sterilizing fluid, the sterile air supply conduit, the filling conduit for the contents, or the passage through which the contents pass can be simultaneously cleaned. Ha
It is simple in structure and has an excellent contamination prevention mechanism. There are fewer restrictions on work due to I characteristics, and labor can be saved.1
It provides a linear type or rotary type M. leprae filling machine. (Means for Solving the Problems) As a means for solving the above problems, the present invention provides a filling section partitioned by walls, a container support mechanism in the filling section, and contents provided in the filling section. A product filling nozzle, piping for supplying the contents to the filling nozzle, an air outlet for locally applying positive pressure in the filling section with sterile air, and a flow connecting the filling nozzle and the air outlet in a detachable manner. It is equipped with a channel forming connector and a switching mechanism for switching and connecting the air outlet to a sterile air supply source and a collection tank for cleaning liquid or sterilizing fluid, and the air outlet is connected to a collection tank for cleaning liquid or sterilizing fluid. It is designed to form part of the road. For reasons to be described later, the outlet 7 is provided coaxially with the filling nozzle and in an annular shape around its outer periphery, and the TTC connector for forming the flow path is a cap, and the cap is fastened to the outlet 7. It is effective to form a recovery conduit for cleaning fluid or sterilizing fluid. (Function) The aseptic filling machine of the present invention includes a filling section partitioned by a wall, a container support mechanism for the filling section, an inner container filling nozzle provided in the filling section, and supplying the contents to the filling nozzle. It is equipped with piping and an air outlet for locally creating positive pressure in the filling section with sterile air, but it also includes a flow path forming connector that removably connects the filling nozzle and the air outlet. , a switching mechanism for switching and connecting the air outlet to a sterile air supply source and a cleaning liquid or sterilizing fluid recovery tank is provided, and the air outlet constitutes a part of the cleaning liquid or sterilizing fluid recovery circuit. The characteristic of ras is that it does this. That is, by dividing the filling section by walls, the sterile zone is localized, so the sterile air supply pipe can be made wider and smaller in diameter than when the entire filling machine is installed in a sterile room. As a result, the difficulty of sterilization in open systems, such as those carried out in large-diameter pipes, can be fundamentally resolved by using closed systems. Furthermore, the air outlet blows out the original sterile air during filling operations, and on the other hand, during sterilization or cleaning, it becomes part of the recovery circuit for cleaning liquid or sterilizing fluid, so that the air outlet and the cleaning liquid or sterilizing fluid recovery port are connected to each other. Compared to the case where both are provided, the structure inside the filling part is simplified and the number of entrances and exits opening into the filling part can be reduced, so the frequency of contamination can be significantly reduced. ．． Moreover, during sterilization or cleaning, by connecting the filling nozzle and the air outlet with a flow path-forming fitting and switching the switching mechanism to the recovery tank side, the sterilizing fluid or cleaning liquid can be directly connected to the contents piping and the contents. The air flows through the product filling nozzle, the Mt path forming connector, the air outlet, and finally the air piping, thereby achieving the effect of simultaneously sterilizing and cleaning the product filling system path and the sterile air blowing system path. Especially when it comes to sterilizing the sterile air blowing system, this system can be sterilized as a closed system, so it is possible to use a more reliable M bacteria fluid such as hot water or superheated steam, which is much easier than in the case of a conventional open system. Compared to the application of sterilizing liquid in the flow path, it is possible to obtain exceptionally superior sterility. In addition, by arranging the air outlet coaxially with the filling nozzle and annularly around its outer periphery, and using a cap that can be fastened to the air outlet as a flow path forming connector, the supply of sterile air during filling can be filled. This is done in the desired manner to achieve the most positive pressure around the contents, and switching between filling operation and sterilization or cleaning can be easily done by simply attaching and detaching the cap. (Example) The present invention will be explained below with reference to the drawings. Figures 1 to 4 show an embodiment of a rotary type filling machine of the aseptic filling machine of the present invention. Figure 1 is an explanatory cross-sectional view of the main parts of a rotary-type aseptic filling machine, showing the filling section on the left side of the rotating shaft of the filling machine body, the unloading section on the right side, the sterile air supply pipe, etc. ．． Figure 2 is an explanatory plan view showing the relationship between the filling section and the loading section and unloading section before and after it. Figure 3 is a cross-sectional view of the filling nozzle during cleaning and sterilization. Figure 4 is a piping diagram showing the system of the contents (filling liquid) piping and sterile air piping. In the figure, a rotating wall with a U-shaped cross section is formed by integrating an inner peripheral wall (12) and a clay wall (13) with a rotating table (10), and a fixed outer peripheral wall (14) makes up a filling section ( 15)

The outer peripheral wall (10) is made to be detachable, and a small spacer (16) is provided between the rotating wall and the outer peripheral wall (14) to facilitate the rotation of the rotating wall and to prevent air from blowing out. In the filling section (15), a large number of container seats (11) are installed in a ring shape on a rotary table (10), each of which is provided with a container support (17).

Then, the sterile air supply pipe (21) passes through the switching valve (22).
The air passes through the sterile air distribution pipe (19) and is blown out from the air outlet (9) to the filling section (15). The Wk small gap (16) facilitates air blowing from the filling part (15), making it easy to replace the filling part (15) with sterile air and maintain a positive pressure with sterile air. In addition, the loading section (28) and the loading section (29) are divided by a fixed outer wall (30), two outer walls (3!), a table under the star wheel (32), and a rotating wall. There is.

The filling nozzle and the air outlet for sterile air, which has an annular outlet located on the outer periphery and coaxial with the filling nozzle, are provided immediately above the filling nozzle, improving the ability to prevent contamination of the sterile zone. By attaching a removable flow path forming connector to the filling nozzle and air outlet, the filling pipe for the contents or the passage for the contents to communicate with the sterile air supply pipe can be used during cleaning and sterilization. The sterile air supply line constitutes a part of the cleaning liquid or sterilizing fluid recovery line, and the filling line for the contents or the passage through which the contents pass and the sterile air supply line are simultaneously operated by the same mechanism. This eliminates the need for a separate mechanism to sterilize the sterile air blowing line, as was the case in the past. Also, sterile air outlet (air nozzle)
Since the sterile air supply pipe and sterile air supply pipe constitute a part of the cleaning liquid or sterilizing fluid recovery pipe, there is no need to provide a separate pipe, and the number of pipes and mechanical parts in the filling section is reduced, reducing the risk of contamination. becomes unconstrained. Furthermore, since the sterile air outlet is part of the recovery pipeline for cleaning liquid or sterilizing fluid, cleaning and sterilization are performed in a closed system pipeline. Therefore, cleaning removes foreign substances, and after that, sterilization using hot water or superheated steam becomes possible. Therefore, heat can reach deep layers and complete sterilization can be achieved.
