Be sprinkled on.

[0005]

However, in the above-mentioned conventional apparatus, since the liquid agent is supplied by using the pump, the liquid agent supply pressure is low and the liquid agent is vigorously dispersed in the chamber. Therefore, there is a risk that the sterilization process, the cleaning process, and the like for the chamber and various devices stored in the chamber may become insufficient.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a liquid agent supply device capable of increasing the discharge pressure of the liquid agent from a liquid agent outlet such as a spray nozzle. And

The operation of the liquid agent supply system having the above structure will be described below.

Considering the case of sterilizing the filling and packaging apparatus 1 in FIG. 1, the switching valves 12 and 37 are both switched so as to select the first liquid agent source 13. In this state, the supply pump 33 operates and the germicide is sucked from the liquid source tank 31. The sucked germicide is heat exchanger 3
4 is heated to an appropriate temperature of about 60 ° C., is sent to the liquid agent supply pipe 15 through the switching valve 12, and is guided to the liquid agent supply stage S (FIG. 2) of the outer housing 11 by the liquid agent supply pipe 15.

The bactericide introduced by the liquid agent supply pipe 15 passes through the opening 19 of the outer housing 11 and the opening 23 of the inner cylinder 20 in FIG. It is injected into the tank 21. When the liquid tank 21 is full of germicide,
In FIG. 2, the motor 27 is operated to activate the sprocket 28.
And 22 rotate, so that inside the outer housing 11, the inner cylinder 20 intermittently rotates in the direction of arrow E by 90 °. By this rotation, the liquid agent tank 21 filled with the germicide reaches the liquid agent discharge stage T, that is, the position below the air feed pipe 17, and stops there.

In this state, the compressed air sent from the air compressor 16 (FIG. 1) via the air feed pipe 17 is applied to the germicide stored in the liquid agent tank 21. Thereby, the bactericidal agent is, for example, ² kgfG / cm ²
It is pressurized with a relatively low pressure (gauge pressure). The pressurized bactericide is delivered to the liquid agent discharge pipe 18 through the opening 24 provided in the bottom surface of the liquid agent tank 21 and the opening 30 provided in the bottom surface of the outer housing 11 in FIG. The sent germicide is pressure-fed to the spray nozzles 6 and sprayed from the spray nozzles 6 into the chamber 2. The sprayed disinfectant sterilizes the inner wall surface of the chamber 2 and various devices stored inside the chamber 2.

The disinfectant obtained by sterilizing the chamber 2 and the like flows down to the bottom of the chamber 2 in FIG.
Be recovered by. The recovered germicide is returned to the inside of the liquid source tank 31 by the recovery pump 36.

In FIG. 4, while the sterilizing agent in the liquid agent tank 21 placed on the liquid agent discharging stage T is pressure-fed to the liquid agent discharging pipe 18 by compressed air, in the liquid agent supplying stage S, the liquid agent supplying pipe 15 is used. The bactericide is supplied into the liquid agent tank 21. When the sterilizing agent in the liquid agent tank 21 placed on the liquid agent discharging stage T is used up, the motor 2 in FIG.
7 is actuated to rotate the inner cylinder 20 by 90 °. By this rotation, the liquid agent tank 21 filled with the sterilizing agent is placed again below the air feeding pipe 17. After that, by the compressed air supplied from the air feed pipe 17,
The sterilizing agent is pumped again. After that, the internal cylinder 2
The intermittent rotation of 0 is continuously performed, and the liquid agent tanks 21 filled with the sterilizing agent are sequentially transported to the liquid agent discharging stage T, and the sterilizing agent is continuously pressure-fed.

As a drive control method for intermittently rotating the inner cylinder 20 by 90 °, any method can be used. For example, in the above embodiment using the sprocket driving method, as shown in FIG. 2, projections 38 for position confirmation are provided coaxially with the sprocket 28, and the motor 27 is detected when these projections 38 are detected. By stopping the operation of, the desired intermittent rotation operation can be obtained. Instead of the protrusion 38, a slit or other position display portion can be used. In addition to such a driving method, a positioning mechanism using an indexing cam or a positioning mechanism using an air cylinder and a one-way clutch can be used.

According to this embodiment, the air compressor 16
Since the liquid agent such as the sterilizing agent and the cleaning liquid is pressure-fed to each spray nozzle 6 by the compressed air sent from the liquid agent, the liquid agent can be sprayed at a high pressure from the spray nozzle 6 as compared with the case where the pressure is pumped. Furthermore, in some cases it is possible to dispense with the supply pump. Then, by spraying the liquid agent under the high pressure, accurate sterilization treatment or cleaning treatment can be performed in a short time. In particular,
In the case of the cleaning process, the disinfectant firmly adhered to the inner wall surface of the chamber 2 is scraped off by spraying the cleaning agent under high pressure, so that the cleaning effect is further improved.

The above is the operation when the aseptic filling apparatus 1 is sterilized. With respect to the aseptic filling device 1, the chamber 2 and various devices inside thereof may be washed as a pre-treatment before performing a sterilization process or as a post-treatment when the operation of the device is stopped. The second liquid agent source 14 shown in FIG. 1 is the first liquid agent source 1 when performing such a cleaning process.
Used in place of 3. Specifically, the switching valves 12 and 37 are switched from the first liquid agent source 13 side to the second liquid agent source 14 side. The operation until the cleaning agent delivered from the liquid source tank 31 of the second liquid agent source 14 is sprayed from the spray nozzles 6 into the chamber 2 is exactly the same as in the case of the first liquid agent source 13 described above.

FIG. 5 shows the entire sterilization cleaning system for an aseptic filling and packaging apparatus using another embodiment of the liquid agent supply apparatus according to the present invention. The purpose of the liquid agent supply device used here is to perform the sterilization process and the cleaning process on the aseptic filling device 1 in exactly the same manner as the embodiment shown in FIG. In FIG. 5, the same reference numerals as those used in FIG. 1 indicate the same members, and the description thereof will be omitted.

The sterilization cleaning system shown in FIG. 5 has two liquid agent supply devices, a first liquid agent supply device 40 for supplying a sterilizing agent and a second liquid agent supply device 50 for supplying a cleaning liquid. ing. These liquid agent supply devices 40 and 50
Are four liquid agent tanks 21a, 21b, 21c, 21d
, Liquid agent feed pipes 15 connected to the individual liquid agent tanks 21a to 21d, air feed pipes 17 connected to the individual liquid agent tanks 21a to 21d, and individual liquid agent tanks 21a to 2
1d, and a liquid agent discharge pipe 18 connected to 1d. An air compressor 16 as a compressed air supply source is connected to the air supply pipe 17. The liquid agent discharge pipe 18 is the heat exchanger 3
It is connected to the switching valve 12 via 4. Both liquid agent supply devices 40 and 50 are exactly the same in structure,
The liquid agents stored in the liquid agent tanks 21a to 21d are different. That is, the sterilizing agent is stored in the liquid agent tanks 21a to 21d of the first liquid agent supplying apparatus 40, and the cleaning agent is stored in the liquid agent tanks 21a to 21d of the second liquid agent supplying apparatus 50.

As shown in FIG. 6, valves 39a, 39b corresponding to the liquid tanks 21a to 21d are provided in the middle of the liquid supply pipe 15.
39b, 39c, 39d are provided. Further, the valves 42a, 42b, 42c, 42 are provided in the middle of the air feeding pipe 17.
d is provided. Further, valves 43a, 43b, 43c and 43d are provided in the middle of the liquid agent discharge pipe 18. The opening / closing operation of each of the valves 39a to 39d, 42a to 42d, and 43a to 43d is controlled by the control device 41. Each of the liquid agent tanks 21a to 21d is provided with a pair of liquid level sensors 44a and 44b which detect that the liquid level in each tank has dropped to an allowable minimum and output an electric signal. The output signal is output from one sensor 44b, and the output signal is sent to the control device 41.

The operation of the apparatus shown in FIG. 5 will be described below. In addition, for convenience of explanation from now on, the liquid agent tank 2
1a to 21d in order from the left, the first tank 21a, the second tank 21b, the third tank 21c, and the fourth tank 21d.
I will call it.

First, as shown in FIG. 6, the first tank 21
It is assumed that a is empty and the remaining three tanks 21b to 21d are filled with the sterilizing agent. In this state, the controller 41 controls the liquid supply valve 34a of the empty first tank 21a to be "open", and the second tank 21 adjacent thereto.
The air supply valve 42b and the liquid agent discharge valve 43b of b are set to "open". For convenience, the valves shown in white in the figure are in the "open" state and the valves shown in black are in the "closed" state.
It is in a state.

In the open / closed state of the valve shown in FIG. 6, a liquid agent, for example, a sterilizing agent is pressure-fed by compressed air from the second tank 21b through the valve 43b to be delivered to the liquid agent discharging pipe 18, and the sterilizing agent is In FIG. 5, after being heated by the heat exchanger 34, it is sprayed from the spray nozzle 6 to the inside of the chamber 2 through the switching valve 12. The inside of the chamber 2 is sterilized by the sprayed germicide. The sterilizing agent after the sterilization treatment is recovered from the bottom surface of the chamber 2 into the liquid agent recovery pipe 35,
Switching valve 3 while being sucked by recovery pump 36
7 and flows into the liquid agent supply pipe 15. The bactericide that has flowed in is collected in the first tank 21a through the liquid agent feeding valve 39a in the "open" state in FIG. 6 and is stored therein.

As shown in FIG. 7, while the disinfectant is collected and supplied into the first tank 21a, the second tank 2 next to the disinfectant is provided.
The amount of bactericide in 1b gradually decreases. When the sensors 44a and 44b detect that the amount of the disinfectant has dropped to the permissible limit value, the control device 41 (FIG. 6) switches the open / closed state of the valve as follows. That is, as shown in FIG. 8, the second liquid material feeding valve 39b, the third air material feeding valve 42c, and the third liquid material discharging valve 43c are all “open”.
Is set to. As a result, the bactericide stored in the third tank 21c instead of the second tank 21b is stored in the liquid agent discharge pipe 1
8 will be pumped.

After that, when the sterilizing agent in the third tank 21c is reduced to the allowable limit, as shown in FIG. 9, the third liquid agent feeding valve 39c, the fourth air feeding valve 42d and the fourth liquid agent discharging valve 43d. Is in an "open" state, and the sterilizing agent is pressure-fed from the fourth tank 21d instead of the third tank 21c. After that, storage and pressure feeding of the bactericide are sequentially repeated for each liquid agent tank 21a to 21d, and as a result, the bactericide is continuously pressure-fed from the liquid agent discharge pipe 18 to the spray nozzle 6. After being supplied, the sterilizing agent is continuously sprayed from the nozzle 6 into the chamber 2.

When the aseptic filling device 1 is subjected to a cleaning process using a cleaning agent instead of the sterilization process, the switching valves 12 and 37 are switched to the second liquid agent supply device 50 side in FIG. As a result, the cleaning agent is supplied from the liquid agent tanks 21a to 21d in the second liquid agent supply device 50 toward the aseptic filling and packaging apparatus 1. The operation of each device at that time is exactly the same as that of the above-described first liquid agent supply device 40, and thus the description thereof will be omitted.

Also in this embodiment, since the sterilizing agent is pressure-fed by the compressed air and is sprayed from the spraying nozzle 6 into the chamber 2, the spraying pressure of the sterilizing agent can be increased.

In the embodiment shown in FIG. 5, the heat exchanger 34 is provided at a position downstream of the liquid agent tanks 21a to 21d with respect to the flow direction of the germicide. However, it is also possible to arrange the heat exchanger 34 at the upstream position of the liquid agent tanks 21a to 21d. From the viewpoint of reducing the pressure loss of the sterilizing liquid or the like supplied from the liquid agent tanks 21a to 21d, the heat exchanger 34 is thus connected to the liquid agent tanks 21a.
It is desirable to arrange it on the upstream side of ~ 21d.

In the embodiment described above, all the liquid agents were collected and reused, but this is not always necessary. For example, in the case of the embodiment shown in FIG. 5, a storage tank may be separately arranged and the liquid agent may be supplied from here to the liquid agent tank through the liquid agent supply pipe.

[0040]

According to the liquid agent supply device of the first and second aspects, a liquid agent such as a sterilizing agent is pressure-fed by using compressed air to be sprayed, that is, discharged from a liquid agent discharge port such as a spray nozzle. Therefore, the discharge pressure of the liquid agent from the liquid agent outlet can be increased, and as a result, the inside of the chamber can be surely sterilized and cleaned in a short time. Especially when considering the case of performing a cleaning process for cleaning the disinfectant adhering to the inside of the chamber, the disinfectant liquid adhering to the chamber is forcibly scratched due to the high discharge pressure of the cleaning agent discharged from the liquid agent discharge port. It can be dropped, and the cleaning process can be performed more reliably.

According to the liquid agent supply device of the third aspect, the pressure loss of the liquid agent supplied from the liquid agent tank to the liquid agent ejection port is reduced, and the liquid agent can be ejected from the liquid agent ejection port at a higher ejection pressure. Become.
