TECHNICAL FIELD OF THE INVENTION
The present invention relates to a liquid extraction device for quantitatively extracting a liquid from inside a flexible liquid container containing the liquid.
[0002]
[Prior art]
Conventionally, for example, in a cup dispenser or a cup-type vending machine that provides a beverage by extracting the beverage into a cup, coffee, black tea, oolong tea, etc., a low-acid beverage raw material liquid and a neutral beverage raw material liquid that are easily contaminated by bacteria and the like. The concentrated raw material liquid of the above is sealed aseptically in a flexible bag-shaped liquid container made of polyethylene or the like, and when the beverage is served, the raw material liquid in the liquid container is quantitatively extracted and diluted with cold or hot water. There is a liquid extraction device which is designed to extract the liquid into a cup.
[0003]
As described above, in the liquid extraction device configured to quantitatively extract the raw material liquid from the liquid container, for example, as described in JP-A-6-293348 or JP-A-6-293393, By arranging the extraction port of the liquid container in the state of being inclined downward toward the extraction port formed at one end of the container and arranging the extraction port of the liquid container in the extraction mechanism, the raw material liquid in the liquid container is extracted by gravity action in the extraction port. , And a certain amount of the raw material liquid drawn into the extraction port is extracted by an extraction mechanism.
[0004]
By the way, when the extraction of the raw material liquid is repeated and the remaining amount of the raw material liquid in the liquid container is reduced, compared with the state before the remaining amount of the raw material liquid in the liquid container is reduced, a certain time ( For example, a certain amount of the raw material liquid may not be drawn into the extraction port within a period of time from the start of the raw material liquid drawing after the completion of one extraction to the start of the next extraction. There is a problem that the quantitativeness varies in a decreasing direction.
[0005]
Further, when the remaining amount of the raw material liquid in the liquid container decreases, the liquid container becomes wrinkled, and a phenomenon that the raw material liquid remains in the wrinkled portion occurs. Despite the presence of, the fixed amount of the raw material liquid cannot be drawn into the extraction port, and the liquid container needs to be replaced early.
[0006]
Then, for example, as described in Japanese Patent Publication No. 3-1997, the remaining amount of the raw material liquid in the liquid container is reduced, so that the liquid container is opened flat and the extraction port of the liquid container is opened. There is a structure in which the other end opposite to the above is wound by a spring to apply a pressure to draw the raw material liquid in the liquid container to the extraction port and to prevent the liquid container from wrinkling.
[0007]
Also, as described in Japanese Patent Publication No. 6-45397, the liquid container is pressed flat from the upper surface of the liquid container with a pressing plate in a state where the liquid container is opened flat, and the raw material liquid in the liquid container is supplied to the extraction port. There is a structure in which a suction pressure is applied and the raw material liquid remaining in the wrinkled portion is forcibly pushed out even if the liquid container is wrinkled.
[0008]
[Problems to be solved by the invention]
However, in each of the structures described in the above publications, the liquid container must be disposed in the liquid extraction device with the liquid container opened flat, and a wide liquid container that secures the content of the raw material liquid is used. In such a case, only one liquid container can be arranged in the liquid extraction device, or when a plurality of liquid containers are arranged in parallel in the liquid extraction device, the liquid extraction device becomes large in the width direction.
[0009]
Therefore, for example, in the case of a liquid extraction device in which the liquid container is bent in a substantially U-shape and arranged in a small size, the structure described in each of the above publications cannot be applied, and the residual liquid in the liquid container described above cannot be applied. As the amount decreases, the problem that the quantitativeness of the raw material liquid varies in the decreasing direction and the problem that the raw material liquid remains due to wrinkling of the liquid container cannot be solved.
[0010]
The present invention has been made in view of such a point.For example, even when the liquid container is bent in a substantially U-shape and arranged in a small size, the liquid in the liquid container is reduced, so that the quantitativeness of the liquid is reduced. It is an object of the present invention to provide a liquid extraction device that can prevent the liquid from remaining in the liquid container by wrinkling in the direction or wrinkling.

Then, in order to obtain a beverage by operating the dispenser, the cup 2 is placed on the extractor 1 from which the desired type of beverage is extracted, that is, on the snowboard 42 of the saucer 43, and the desired type of beverage and the amount of extraction are set. The extraction button 45 of the corresponding front door 33 is pushed and operated.
[0060]
When the extraction button 45 is operated, the pressing plate 116 of the corresponding type of fixed quantity extracting means 4 is retracted by a distance corresponding to the amount of extraction to form a call space 114 on the front side of the pressing plate 116. As a result, the fixed quantity extraction bag portion 55 of the extraction port portion 52 can protrude in the direction of the inlet space 114, and the raw material liquid in the liquid storage bag portion 51 of the liquid container 3 is displaced by its own weight. It is called into the fixed quantity extraction bag section 55 through the inlet section 56 (see FIG. 1). At this time, an amount of the raw material liquid corresponding to the retreat amount of the pressing plate 116 is drawn into the fixed quantity extraction bag section 55.
[0061]
Subsequently, the upper pinch body 117 moves to the closed position, and the lower pinch body 118 moves to the open position. As a result, the inlet portion 56 of the extraction port 52 is closed by the upper pinch body 117, and the raw material liquid in the liquid storage bag 51 is prevented from flowing into the extraction port 52. When the lower pinch body 118 moves to the open position, the outlet 57 of the extraction port 52 is opened, and the raw material liquid drawn into the fixed quantity extraction bag section 55 flows from the lower end of the outlet 57 to the extraction section 1. Is extracted in the cup 2 or the mixing ball 41 disposed in the mixing bowl. Further, the pressing plate 116 moves forward and forcibly presses the fixed amount extraction bag portion 55 against the movable frame 112, and the raw material liquid in the fixed amount extraction bag portion 55 is forcibly extracted.
[0062]
Subsequently, after a lapse of a predetermined time in consideration of the time during which the source liquid from the outlet 57 of the extraction port 52 is eliminated, the upper pinch body 117 is moved to the open position, and the lower pinch body 118 is moved to the closed position. Move to As a result, the quantitative extraction means 4 returns to the initial standby state, completes a series of extraction operations of the raw material liquid, and stands by for the next raw material liquid extraction operation.
[0063]
On the other hand, in response to the operation of extracting the raw material liquid, the chilled water supply device 5 operates to extract the cold water into the cup 2 of the extraction unit 1 or to the mixing ball 41, and to extract the raw liquid in the cup 2 or the mixing ball 41.
