Abstract
Provided are a method and an apparatus for packaging liquids in which bubbles are suppressed as much as possible when carbonated and stock liquids are fed to accurately fill a container with carbonated drinks. Included are means (9,7,11) for conveying the container (1), means (3) for filling the container with the carbonated liquid, means (4) for filling the container with the stock liquid, and means (5) for covering the container, filled with the carbonated and stock liquids, with a cap.
Description
- The present invention relates to a method, for use in an industry, such as one producing carbonated beverages in containers, like soft or fruit drinks, of packing liquids, and to an apparatus for packing the same.
- In an industry producing carbonated drinks in containers, such as soft or fruit drinks, conventionally, syrup and treated water are first mixed together to a predetermined sugar content. Carbon dioxide gas is then absorbed in a carbonation tank to form a carbonated liquid. A device used exclusively for filling, fills containers with the carbonated liquid. Desired carbonated drinks are thus produced.
- In recent years, as commercial products on the soft and fruit drink market have become diversified, there has been a demand for a single packing apparatus to handle many types of products (different types of syrup and shapes of containers), for improving production efficiency and reducing personnel as well as manufacturing cost.
- When syrup is changed during a filling cycle, the previously fed flavor must be removed and the path along which it is conveyed must be completely cleaned. Such an operation consumes a great deal of time during which the packing apparatus ceases, thus significantly reducing productivity.
- A filling nozzle is inserted into the mouth of a container into which a carbonated drink is filled. The portion around the mouth is sealed, and pressure equal to that of the carbonated drink is supplied into the container. After the pressure inside the container has become substantially equal to that of the drink, the filling process begins under such pressure while the drink is prevented from bubbling as much as possible.
- A filling method is employed in which the liquid is filled until degassing pores in the nozzle are filled with the liquid. Once the pores are filled, no more liquid is fed. In this method it is impossible to control the flow rate during filling, and it is therefore difficult to control the filling time and to suppress the bubbles of the liquid during filling.
- Furthermore, in many cases the liquid bubbles when the pressure inside the container is removed after it has been filled, thus making it difficult to accurately fill the container with the carbonated drink.
- In this industry, there has been a demand to accurately fill containers with liquids in a short period of time without causing unnecessary pressure inside the container or causing the liquid to pour out.
- However, when the filling method is actually employed to fill a fixed amount of liquid into the container, it requires the processes of pressurizing, filling and decreasing pressure, after filling has been completed, for each container. In addition, because the liquid is fed by gravity, the flow rate cannot be controlled. When packing liquids on a large scale, it is impossible to reduce the filling time for each container.
- The present invention has been made to solve the above problems. The object of this invention is to provide a method and an apparatus for packing liquids. A container being conveyed is filled first with a carbonated liquid and then with a stock liquid, and then the mouth of the container is capped, whereby it is possible to suppress bubbles as much as possible while the carbonated and stock liquids are filled and to accurately fill carbonated drinks. Driving means is linked to a fixed-amount feed member facing one end of a sending pipe in a frame. The amount of carbonated liquid to be fed is adjusted through numerical control. The liquid can be filled accurately at a high speed through a porous injecting member connected to the sending pipe.
- The container being conveyed is filled first with the carbonated liquid and then with the stock liquid, and then the mouth of the container is capped, whereby it is possible to suppress the bubbles as much as possible while the carbonated and stock liquids are filled and to accurately fill the carbonated drinks.
- It is not necessary to pressurize the inside of the container, and therefore the processes of pressuring and decreasing pressure can be omitted. The container is not damaged during the pressurizing process, and it is safe. The amount of liquid to be filled into the container is accurately controlled at a high speed. The carbonated liquid is filled into the container under atmospheric pressure, i.e., an open filling operation can be uniformly performed.
- Various advantageous effects, such as those described below can be obtained. The carbonated liquid and syrup serving as the stock liquid are filled separately during filling. The aroma, flavor and the color of the stock liquid do not adhere to the inside of the fixed-amount feed member. Cleaning operation can be performed easily and quickly before or after filling is carried out.

member 7 of the conveyingmeans 2. The stock liquid filling means 4 is used for filling the containers 1, which have already been filled with the carbonated liquid, with a stock liquid. An ordinary piston-type filling machine may be used as the filling means 4. In this embodiment, a double-head type is used to suit the two containers 1 and 1 being conveyed simultaneously. - As shown in Fig. 5, a filling
nozzle 44 is lowered through asupport 43 which is fitted around a column 42 standing on one side of theframework 20 so that thesupport 43 can move up and down along the column 42. A liquid-feedingmember 46, which is a piston/cylinder, is disposed above the fillingnozzle 44 to which astock liquid tank 48 is connected through apipe 47. Ahose 45 connects the fillingnozzle 44 to the liquid-feedingmember 46. - Though not shown, the liquid-feeding
member 46 may be disposed below thesupport 43 and push the stock liquid so as to feed it after it has been fed from thestock liquid tank 48. - A threaded
piece 51 is attached to thesupport 43, whichpiece 51 is mated with a threadedshaft 50 rotatable clockwise or counterclockwise by drivingmeans 49, such as a servomotor. Signals from a controller (not shown) move thesupport 43 up and down in predetermined timing. - The above-mentioned covering means 5 next to the stock liquid filling means 4 is disposed in the path along which the containers 1 are carried by the feeding
member 7 of the conveyingmeans 2. The covering means 5 is used for covering the container 1 with acap 52, the container 1 having already been filled with the carbonated and stock liquids. The covering means 5 is of a double-head type to suit the two containers 1 and 1 being conveyed simultaneously. - As shown in Fig. 6, an attaching
member 54 is fixed to asupport post 53 standing on theframework 20 so that the attachingmember 54 can move up and down. A cappingshaft 56 rotatable by drivingmeans 55 is suspended from the attachingmember 54. Acap holder 57 is attached to the lower end of the cappingshaft 56 so that it is free to open and close. - Thus, the
cap holder 57 receives thecap 52 from cap lining/feeding means 58 disposed between the stock liquid filling means 4 and the adjacent covering means 5, and tightens thecap 52 to a predetermined amount. - In the above-described structure of an embodiment of this invention, when a carbonated drink containing, e.g., fruit is filled, the carbonated liquid for dilution flows from the
tank 22 to theframe 14, thus filling theaccommodating chamber 21. At this phase, a signal is transmitted to the driving means 16 in accordance with a numerical value input to the control means 17, thus operating the driving means 16. When therotator 28 is rotated a predetermined number of revolutions, a fixed amount of the carbonated liquid sealed between the fixingmember 27 and therotator 28 is discharged to the sendingpipe 25 through one end of the fixed-amount feed member 15. - While the container 1 is carried to the feeding
member 7 of the conveyingmeans 2, the driving means 16 is operated to drive therotator 28. The pressure under which therotator 28 feeds the liquid increases more than the pressing force of thespring 39, thus opening thevalve 38. The fixed amount of the carbonated liquid is thus discharged without causing a decrease in the pressure of the carbonated liquid. The carbonated liquid passes through the microporous pores 40 in the sprayingmember 41 and spouts into the container 1 at atmospheric pressure; so-called open filling is performed. - It is desirable that the numerical value to be input to the control means 17 be set so that the container 1 is filled with the carbonated liquid in an ideal manner. For instance, the amount of the carbonated liquid to be filled is such that a small amount is fed at the beginning of feeding, and after a certain amount has been fed, as much liquid as possible is fed at the same time to improve the efficiency of feeding. At the end of feeding, the liquid is gently fed to prevent it from pouring out of the container 1 due to feeding pressure.
- At this phase, the pressurized carbonated liquid, which has been sent from the fixed-
amount feed member 15, permeates through themany pores 40 in the inner wall of the sprayingmember 41 of the injectingmember 19. The pressure of the liquid changes as it flows through thepores 40, that is, it changes from a high pressure to pressure close to atmospheric pressure, which is normal pressure, inside the container 1. Thus the pressure of the carbonated liquid which has been pressurized decreases gradually, and becomes substantially equal to atmospheric pressure when the liquid reaches the outer wall of the sprayingmember 41 after having passed inside themember 41. The carbonated liquid bubbles as its pressure changes rapidly, and is separated into carbon dioxide gas and a particulate liquid. - However, since the carbon dioxide gas itself is very soluble in water, it is immediately absorbed into the particulate liquid in the microporous pores 40. The carbonated liquid becomes stable and returns to being the same liquid as before being fed. The container 1 is filled with the fixed amount of the carbonated liquid with the aid of the fixed-
amount feed member 15. In this way, a carbonated beverage mixed with the stock liquid is produced. - The packing method thus described is capable of immediately reducing both a decrease in the amount of carbonated liquid for dilution and a loss of the carbon dioxide gas. Both problems are due to a foaming phenomenon, and are conventional problems which have to be solved.
- The container 1 thus filled with the carbonated liquid is carried by the conveying
means 2 to the stock liquid filling means 4, which is used for the next step. A fixed amount of the stock liquid is fed into the container 1 by the fillingnozzle 44 after it has pass through the liquid-feedingmember 46. At this time, the bubbles of the carbonated liquid which has already been fed are suppressed, and the liquid is filled with a high degree of accuracy. - The
cap 52 is sent from the cap lining/feeding means 58 to the container 1 which has been carried by the conveyingmeans 2 and has reached the covering means 5. Thecap 52 is tightened with a predetermined pressure by the clamping and rotation of thecap holder 57, this rotation being caused by the driving means 55. The container 1 as a product is conveyed onto the carrying-out member 11. - The packing apparatus A is disposed in such a manner that the
means member 7 of the conveyingmeans 2. Such an arrangement makes it possible to render the packing apparatus A smaller and to manufacture it at low cost.
