なかつた。 A plastic container forming machine is a series of machines that melt a synthetic material, blow air into a plastic container, fill the container with a sterile filling, such as a fluid food or medicine, and then seal the opening of the container. It is a machine that can repeat the process. Since the sterile air blown into the container when it is molded by this machine must be exhausted when filling the container, the device is equipped with piping for an air supply system and an exhaust system. With conventional machines, it was not possible to maintain the air supply system piping and exhaust system piping for molding in a sterile state during the entire operation, and therefore it was not possible to fill the mold with aseptic filling.

Move to blow filling station as shown. A blow-molding and filling head 10 of the forming-filling device 2 is provided above the blow-filling station. A tube member 11, which will be described later, descends from the blow molding filling head 10 and is inserted into the opening of the parison 5, and the neck of the parison 5 is sandwiched between the dies 6, 6 and the tube member 11 in an airtight manner. Sterilized pressurized air is blown into the parison 5 from the supply/exhaust port 12 through the pipe member 11, and the container 13 is blow-molded. The injection pipe 14 housed in the center of the tube member 11 is lowered, its injection port is opened, and the filling material is injected. Accordingly, the air inside the container 13 is discharged to the outside air from the air supply/exhaust port 12 as will be described later. Injection tube 1
4 is connected via a hose 15 to a metering cylinder 17 which supplies a fixed amount of filling from a tank 16. The metering cylinder 17 is reciprocated through a constant stroke by an attached hydraulic cylinder. When the container 13 is filled with the filling material, the injection tube 14 and the tube member 11 are raised, and the opening of the container 13 is sealed by the obturator 31 of the blow die device 3.

A blowing mandrel 21 is fixed to the lower end of the tube member 11, and the lower end is formed into a size and shape that airtightly sandwiches the neck of the parison held by the die 6 when the mandrel 21 descends. ing. An injection pipe 1 is located in the center of the pipe member 11 and the blowing mandrel 21.
4 is provided so as to be freely movable up and down, and a gasket 22 is provided between the pipe member 11 and the pipe member 11 to maintain airtightness. The gap between the blowing mandrel 21 and the injection pipe 14 forms a passage 23 for blowing pressurized air, which communicates with the supply/exhaust port 12 provided in the pipe member 11 .

The lower end of the valve 24 serves as a valve seat that comes into close contact with the valve 24.
The gap between the central axis 25 and the injection tube 14 forms a passage 26 for the filling, which is connected to the hose 15 shown in FIG. 1 at the upper part of the injection tube 14. Pipe member 11
The air supply/exhaust port 12 is connected to an air supply system circuit 18 and an exhaust system circuit 19 via a control valve 27 . When the control valve 27 is switched, the A side connected to the air supply/exhaust port 12 is connected to either the B side connected to the air supply system circuit 18 or the C side connected to the exhaust system circuit 19. The air supply system circuit 18 is a sterilization filter 28
is connected to the pressurized air source 29. The terminal of the exhaust system circuit 19 opens into the disinfectant solution in the disinfectant tank 30. The tank 30 is provided with an opening that communicates with the atmosphere from above the liquid level.

い。 Next, we will discuss the effect. When blow molding the container 13, the central shaft 25 is raised relative to the injection pipe 14, the passage 26 is sealed by the valve 24, and in this state the tube member 11 is lowered. Control valve 27 is closed on B side, AC
Although the disinfection tank 30 is switched to the open state, the disinfection tank 30
There is no risk of outside air entering the exhaust system circuit 19 from the outside. A blowing mandrel 21 is inserted into the opening of the parison held by the die 6, and the parison is airtightly held between the blowing mandrel 21 and the die 6. During this time, the parison 5, whose lower end is sealed, expands slightly in the die 6 and then deflates slightly, and sterile air is released from the opening. There is no risk of intrusion into 5.

閉塞器31により容器13の口が密閉される。 Next, the control valve 27 is switched to close the C side and open the AB, and pressurized air is blown into the parison 5 via the sterilization filter 28 through the supply/exhaust port 12 and the passage 23, and the parison 5 conforms to the inner shape of the die 6. The container 13 is formed along the same line. Subsequently, when the control valve 27 is switched to AC communication and the injection pipe 14 is lowered to a predetermined height, the central shaft 25 is slightly lowered, the valve 24 is opened, and the filling material is injected into the container 13. The air inside the container 13 pushed by the filling is released into the disinfectant solution in the disinfection tank 30 through the passage 23 and the control valve 27, and escapes to the outside air. As the filler is injected, the injection pipe 14 rises, and when a predetermined amount has been injected into the container 13, the valve 24 closes and the blowing mandrel 21 rises. At the same time, the mouth of the container 13 is sealed by the obturator 31.

きい。 As is clear from the above description, according to the present invention, the terminal of the exhaust system circuit is opened below the liquid level of the sterilization tank to prevent backflow of outside air containing bacteria, and the sterilized air supply system circuit and control valve are used. Since it can be switched, both the molding and filling operations of plastic containers can be performed continuously in a sterile state.This is a practical example of a plastic container molding machine that is capable of filling sterile fillings such as food or pharmaceutical products. The effects and benefits are extremely large.
