Description

[Detailed explanation of the idea] This project concerns the improvement of a bottling machine.

A conventional bottling machine will be explained with reference to FIGS. 1 to 7. Reference numeral 41 in FIG. 2 shows the bottling machine, and FIG. 1 shows the structure of the bottling machine 41, respectively. In FIG. 1, one end of a pipe 2 is connected to a rotary joint 1 attached to a lid d, a stop valve 3 is interposed in the pipe 2, and the other end of the pipe 2 is inserted into a cleaning tank 4. , the tank 4 is provided with a heater 5 for heating the cleaning liquid. A pump 7 and a stop valve 8 are interposed in a pipe 6 leading from the cleaning tank 4 to the liquid supply passage c, and a stop valve 9 is also interposed in the liquid supply passage c. Also, the rotary joint 1 and the manifold 11 are connected to the piping 10.
The manifold 11 and the diaphragm on-off valve 14 are connected by a pipe 13 with a stop valve 12 interposed therebetween. Furthermore, the air passage
An air passage restricting device 33 is provided on the inlet side of _k1 . Further, the diaphragm type on-off valve 14 has a lower valve body 16 having a protrusion 15 as shown in FIG.
, an upper valve body 18 having a hole 17, a diaphragm presser 20 having a hole 19, and a lower valve body 1.
6 and a diaphragm holding device 20, a diaphragm holding device 22 that holds the diaphragm 21, and a diaphragm holding device 22 that holds the diaphragm 21.
a shaft 23 that penetrates through the diaphragm clamp 22 and is slidably fitted to the diaphragm holding tool 20; and a seal packing holder 25 that has a hole 24 and is integrally fixed to the shaft 23. and,
A seal packing 26 fixed to one end of the holder 25 and a plurality of holes 2 provided in the lower valve body 16.
Seal packing sheet 28 integrally fitted to 7
and a spring 31 interposed between a spring receiver 29 attached to one end of the upper end of the shaft 23 and a spring receiver 30 integrated with the diaphragm holding device 20. The end of the piping 13 is connected to the hole 32 opened on the side, the end of the air passage k ₁ near the tank b is connected to the lower part of the lower valve body 16, and the end of the air passage k 2 near the bottling valve i is connected to the end of the air passage k ₁ near the tank b. The end is connected to the hole 27. In addition, one tank-side air passage k ₁ is connected to one diaphragm type on-off valve 14, and one bottling valve-side air passage k ₂ (1
A plurality of bottling valves i are attached to _each of the diaphragm on-off valves 14). The total flow rate flowing out of the air passage _k2 near the bottling valve is equal to the total flow rate. Further, the hole 17 of the upper valve body 18 is connected to the atmosphere and an air pressure supply source through a three-way valve (not shown), and is communicated with the atmosphere during bottling. Next, the air passage restricting device 33 will be explained with reference to FIGS. 4 to 7. A bearing 34 integral with the lid d
A shaft 36 is rotatably mounted via a collar 35 and a lever 37, and a lever 37 is integrally fixed to the upper end of the shaft 36. In addition, a groove 38 that engages with the shaft 36 is formed in the bubble-blocking hollow umbrella n disposed at the upper part of the tank b in FIG. 1, and an air passage _k1 is formed in the hollow umbrella n.
A diaphragm plate 39 corresponding to the tank b is integrally attached, and a pin 40 is provided to protrude from the inner wall of the tank b in the circumferential direction. Possibly placed. Next, the outline of the bottling machine 41 will be explained with reference to FIG.
Reference numeral 1 denotes a large number of bottle stands j that are arranged at predetermined intervals in the circumferential direction and that revolve around the center of the bottle filling machine 41.
(see Fig. 1), the bottles p fed by the bottle feeding screw 42 and the conveyor 43 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 the bottles are packed in the bottle filling machine 41. After being bottled, the bottle guide 45 and star wheel 47
The bottles are then discharged by a conveyor 48.

In the bottling machine shown in FIGS. 1 to 7, after the bottling operation is completed, the filling liquid remaining in the tank b is collected via the liquid supply passage c and the stop valve 9 to a filling liquid tank (not shown). After that, open the on-off valve 49 provided on the lid d, and open the stop valve 9.
Fresh water is then supplied into the tank b by a means not shown through the liquid supply passage c to fill the tank b, and the bottling machine 41 is operated idly. Then,
The fresh water that has flowed into the air passage _k1 is discharged to the outside of the machine via the diaphragm type on-off valve 14, the air pipe _k2 , and the bottling valve i, and the fresh water that has flowed into the liquid passage m is discharged to the outside of the machine via the bottling valve i. At the same time, the liquid, bubbles, etc. in the air passages m, k ₁ , k ₂ are also discharged to the outside of the machine, and the bottling machine 41 is roughly cleaned. Next, the stop valve 9 is closed, and the fresh water in the tank b is discharged from the bottling valve i through the same route as described above. Further, the bottle p fed by the conveyor 43 is fed by the bottle feeding screw 42 to the space qr of the 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.
, and fill the space between r and q with bottle p, and at the same time, fill the cleaning tank 4 with cleaning liquid. When this state is reached, the stop valves 3, 8, and 12 are opened. The hole 17 is open to the atmosphere, and 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 pipe 6.
→ pump 7 → stop valve 8 → liquid is supplied to tank b via liquid supply passage c. When the bottling tank b is filled with cleaning liquid in this way, the on-off valve 49
Close it and start cleaning. That is, the canopy n is rotated via the lever 37, the shaft 36, and the groove 38 of the canopy n, and the opening area of the air passage _k1 is narrowed by the aperture plate 39. At this time, since the hole 17 is open to the atmosphere, the seal packing 26 is separated from the seat 28 by the action of the spring 31, and the cleaning liquid flows from the tank b → the throttle plate 39 → the air passage k ₁ → the hole 24 → Projection 15 → 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 → liquid supply passage c. On the other hand, the liquid in the liquid passage m is transferred from the bottling valve i to the bottle p (between q and r, it is communicated with the bottle p, and between r and q, the bottling valve i is closed by means not shown in the figure via the switching lever h, and the bottling valve i is connected to the bottle. (Not connected to p) → Bottling valve i → Air pipe k ₂ → Hole 27 → Seat 28 → Hole 24 → 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 -> Liquid is circulated to tank b via the liquid supply passage c.

During the above cleaning, it is necessary to flow the cleaning liquid into the air passage k ₁ and the liquid passage m as described above, but the passage resistance of the air passage k ₁ is very small compared to the liquid passage m, and the cleaning liquid from the tank b Most of them are air passages k ₁
It flows into As a countermeasure, the opening area of the air passage _k1 was narrowed down by a throttle plate 39 provided on the umbrella body n, so that the cleaning liquid flowed almost evenly into the liquid passage m and the air passage _k1 . However, in order to narrow down the opening area of the air passage _k1 , the operator has to operate the lever 37 at the top of the tank b, which is troublesome and dangerous. Furthermore, the air passage restricting device 33 present in the tank b becomes dirty due to long-term use, but the dirt cannot be completely removed by cleaning only with the non-decomposition cleaning described above, so it is necessary to periodically Currently, the tank lid must be removed and disassembled for cleaning, which ultimately undermines the advantages of non-disassembly cleaning and creates opportunities for contamination by bacteria.

This proposal addresses the above-mentioned problems, and includes a liquid supply passage c, a bottling tank b installed in the center of the bottling machine and communicating with the liquid supply passage c, and a bottling tank b.
