Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bottling machine equipped with an air passage leading from the upper part of the bottling tank to the bottling valve and a liquid passage leading from the lower part of the bottling tank to the bottling valve.

This type of conventional bottling machine is explained with reference to Fig. 1. A is a main body frame, and a bottling tank b is installed in the upper center of the main body frame a;
A liquid supply passage c is connected to the bottom of the liquid supply passage c.

The bottling tank b is sealed with a lid d, an air passage e and an air discharge passage f are connected to the top space of the tank b, and a liquid level control float g is floated on the liquid level in the tank b.

Further, a plurality of sets of bottling valves i equipped with a switching lever h are mounted on the outer periphery of the main body frame a, and a bottle stand j is mounted so as to be able to rise freely opposite to the bottling valves i.

Furthermore, a diaphragm type on-off valve l is interposed in the air passage k leading from the upper part of tank b to the bottling valve i, and the lower part of the tank b and the bottling valve i are connected by a liquid passage m, and a bubble-blocking valve is installed in the upper part of the tank b. A hollow umbrella body n is provided.

For hygiene reasons, the bottling machine must be cleaned and sterilized every day after bottling work is completed.

In the conventional bottling machine configured as described above,
When the bottling work is completed, the remaining liquid in tank b is discharged from liquid supply passage c, and then lid d and float g of tank b are removed, and bottling valve i is closed with switching lever h to stop the liquid supply. Fresh water is supplied from passage c into tank b. When the fresh water overflows from tank b, when the bottling valve i is switched using the switching lever h, the fresh water in the tank b flows out of the machine from the air passage k and the liquid passage m through the bottling valve i, and is transferred to the tank b. , the liquid remaining in the air passage k, liquid passage m and bottling valve i is washed out.

After washing with a large amount of fresh water, hot water of 80 to 90°C is supplied for further sterilization.

When sterilizing medicine, the bottling valve i is closed, the tank b, the air passage k, the liquid passage m, and the bottling valve i are filled with the medicine liquid and held for a certain period of time to perform sterilization. This is because discharging a large amount of chemicals is uneconomical and poses problems in terms of wastewater treatment.

In addition to carrying out such cleaning and sterilization work every day after the bottling work is completed, every 1 to 2 weeks, the bottling valve i and the switching lever h are removed and disassembled for cleaning, and the tank b, air passage k, and liquid passage are It is necessary to clean the inside of m with a brush, etc.

The above is the conventional cleaning and sterilization method for bottling machines.
Since a large amount of fresh water and hot water are required for daily cleaning and sterilization work, it is extremely uneconomical and also has the disadvantage that bacterial contamination occurs when the tank lid d and float g are reassembled.

The present invention was developed to address the above-mentioned drawbacks, and includes a liquid supply passage, a bottling tank connected to the liquid supply passage, and a bottling tank connected to the lower part of the bottling tank.

A bubble-blocking hollow umbrella body n is placed on the bubble-blocking hollow umbrella n so as to be slidable in the circumferential direction.

Furthermore, referring to FIG. 3, the outline of the bottling machine 41 will be explained. The bottle filling machine 41 includes a large number of bottle stands j arranged at predetermined intervals in the circumferential direction and revolving around the center of the bottle filling machine 41, and the bottles p fed by the bottle feeding screw 42 and the conveyor 43 are placed in a bottle guide. The bottles are placed one by one on the bottle stand j while being fed by the bottle guide 45 and the star wheel 46, and then filled in the bottle by the bottle filling machine 41.
7 and is discharged by a conveyor 48.

Since the embodiment shown in FIGS. 2 to 8 is constructed as described above, after the bottling operation is completed, the remaining filling liquid in the tank b is filled via the liquid supply passage c and the stop valve 9, which is not shown. Collected in liquid tank.

After that, open the on-off valve 49 provided on the lid d,
Fresh water is supplied into the tank b by a means not shown through the stop valve 9 and the liquid supply passage c, and when the tank b is full and the bottling machine 41 is operated idly, the fresh water flowing into the air passage _k1 is opened and closed by a diaphragm type. The fresh water is discharged from the machine through the air passage k ₂ and the bottling valve i via the valve 14, and the fresh water that has flowed into the liquid passage m is discharged from the machine from the bottling valve i. The liquid, foam, etc. in ₁ and _k2 are also discharged to the outside of the machine, and the bottling machine 41 is roughly cleaned. The stop valve 9 is closed, and the fresh water in the tank b flows through the same path as described above and is discharged from the bottling valve i.

Further, the bottle p fed by the conveyor 43 is fed by the bottle feeding screw 42 to the space between qr and bottle filling machine 41 via the star wheel 46 and the bottle guide 45, and then the bottle guide 45 is passed through the bottle guide 44.
Fill the bottle p between r and q, and at the same time fill the washing tank 4 with washing liquid.

In this state, the stop valves 3, 8, 1
2 is opened, and the hole 17 is open to the atmosphere. When the pump 7 is operated and the cleaning heater 5 is also operated, the heated cleaning liquid flows from the cleaning tank 4 to the piping 6, the pump 7, and the stop valve 8. and is supplied to tank b via liquid supply passage c.

After the bottling tank b is filled with the cleaning liquid in this way, when the on-off valve 49 is closed, cleaning is started.

That is, when the lever 37 is rotated, the canopy body n is rotated by the shaft 36 through the groove 38 of the canopy body n, and the aperture plate 3
9 narrows down the opening area of the air passage _k1 .

As described above, since the hole 7 is open to the atmosphere, the seal gasket 26 is separated from the seat 28 by the action of the spring 31, and the cleaning liquid is distributed to the tank b, the throttle plate 39, the air passage k ₁ , the hole 24, Protrusion 1
5, hole 32, stop valve 12, piping 13, manifold 11, piping 10, rotary joint 1, piping 2, stop valve 3, cleaning tank 4,
It circulates to tank b via piping 6, pump 7, stop valve 8 and liquid supply passage c.

On the other hand, the liquid in the liquid passage m is supplied to the bottle valve i, bottle p(q
- r is in communication with bottle p, and between r and q, bottling valve i is closed via a switching lever h by means not shown and is not communicated with bottle p), bottling valve i, air passage k ₂ , hole 27 , sheet 28, hole 2
4, protrusion 15, hole 32, stop valve 12, piping 13, manifold 11, piping 10, rotary joint 1, piping 2, stop valve 3, cleaning tank 4, piping 6, pump 7, stop valve 8
and circulates to tank b via liquid supply passage c.

Here, to explain in detail about the bottle p between q and r, since the bottle filling valve i is opened and communicating with the bottle p, even if the bottle p is filled with liquid, the bottle filling valve i is connected to the bottle p from the liquid passage m. The filled liquid sequentially flows out into the air passage _k2 through the outlet side passage of the bottling valve i. In this example, although not shown, the bottle filling valve i is a bottom filling type, so the liquid in the bottle P is supplied from the bottom and flows out from the top, so there is no stagnation, and the drug is not used. Even afterwards, it is washed away by the circulation of fresh water.

After washing with clean water in this way,
Since the heated cleaning liquid can be circulated without disassembling part of the bottling machine 41 to perform non-disassembly cleaning similar to normal bottling work, the number of work steps can be greatly reduced.

Moreover, since it is a circulation system, even the end parts of the bottling machine 41 are cleaned at a uniformly high temperature, which improves the sterilization of the parts to be cleaned.

Furthermore, since the cleaning method can be used in the same way as for normal bottling work, there is no leakage of the heated cleaning agent as in the past, which saves resources and energy. Since no emissions are released, the working environment is improved and the growth of indoor bacteria and mold is inhibited.

Furthermore, since the bottling machine 41 does not have to be disassembled, bacterial contamination during reassembly can be prevented.

Moreover, since the air passages were narrowed using the conventional bubble shielding plate 33, the air passages k ₁ and k ₂ and the liquid passage m
The liquid flow resistance can be easily adjusted, improving the circulation of the cleaning cycle and making it practical.

Furthermore, since the expansion device can be formed without providing a valve in the air passage k, there is no need to extensively modify the existing bottling machine.

Furthermore, a hole 24 is provided in the seal packing holder 25 of the diaphragm type on-off valve 14, and the lower valve body 1
The cleaning liquid circulation circuit is formed by simply opening the hole 32 located outwardly from the protrusion 15 of 6 and connecting the hole 32 to the rotary joint 1 via the piping 13, the manifold 11, and the piping 0. Modifications can be kept to a small scale.

In the embodiments illustrated in FIGS. 2 to 8,
Instead of the piping 2, manifold 11, and piping 13, as shown in FIG. It is also possible to provide the same effect as the embodiments shown in FIGS. 2 to 8.

Furthermore, in the embodiments shown in FIGS. 2 to 8 or 9, the tank 4, piping 6, pump 7, and stop valve 8 may be omitted, and the piping 2 or the rubber hose 51 may be connected to the drain. In this case, the cleaning liquid is continuously supplied to the liquid supply passage c to maintain the liquid in the tank b at a constant level, and the cleaning liquid after cleaning is discharged to the drain, making it impossible to recover the cleaning liquid. .

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. .
