Alternatively, a stainless steel syrup tank is placed, and the syrup raw material is replenished and stored in this syrup tank. When selling juices, syrup raw materials are sucked up from this syrup tank using a pump through a pipe and discharged into a paper cup. At the same time, it has been conventionally known that syrup raw materials are diluted and provided as juices by discharging cold water or carbonated water into a paper cup.

[0003]

However, in the case of the syrup raw material discharging apparatus of the cup type vending machine in the above-mentioned prior art, the syrup raw material before being pumped up by the pump always remains in the syrup tank. Become. However, it is necessary to always keep a certain amount of syrup raw material in the syrup tank in order to keep the syrup tank from being sold out, so that the remaining old syrup raw material is replenished with new syrup raw material. Therefore, there is a problem that old and new ones are mixed and freshness cannot be maintained.

[0004] In view of this situation, the present invention must be carried out after the cassette-type syrup raw material container previously attached is emptied.
Then, the syrup raw material is replenished to the sub tank from the attached cassette type syrup raw material container. It is an object of the present invention to provide a storage and discharge device for syrup raw materials in a cup-type vending machine in which the old syrup raw materials and the new syrup raw materials are not mixed.

[0005]

The present invention employs the following technical means in order to solve the above-mentioned problems. In the invention according to claim 1, in the cup-type vending machine, a syrup pump for discharging syrup is provided in a sub-tank having an opening formed in an upper portion, and a seesaw is provided on a fulcrum above the sub-tank via a fulcrum. A seesaw member is provided which is fixed to both sides of the seesaw member.
By inserting two pipes into a sub-tank and attaching a cassette type syrup raw material container to each of the two pipes, the syrup raw material is always replenished from the previously mounted cassette type syrup raw material container to the sub tank. Means were adopted. According to the second aspect of the invention, in addition to the first aspect, a technical means is provided in which a water tank for cooling the sub-tank is provided so as to cover the sub-tank.

[0006]

According to the present invention, as a result of employing the above technical means, when one cassette type syrup raw material container is mounted with the sub tank empty, the mounted one becomes heavier and the pipe is inserted to a lower position. The syrup raw material in the cassette type syrup raw material container falls naturally and is replenished until the syrup liquid level in the sub tank reaches the opening of the pipe (FIG. 2).
See).

When the second cassette type syrup raw material container is mounted, the first cassette type syrup raw material container side is lighter by the amount of the refilled syrup, so that the second side is lowered and the pipe connected thereto is inserted to a lower position. At that time, as the first pipe rises, the syrup raw material is replenished from the first cassette type syrup raw material container by an amount corresponding to the rise. In order to sell juices in this state, when the syrup pump discharges the syrup raw material in the sub-tank, the liquid level drops, and the liquid level drops by one.
Syrup is replenished from the first cassette type syrup raw material container (see FIG. 3).

[0008] Each time juice is sold, the syrup raw material is replenished from the cassette type syrup raw material container having the higher seesaw as described above, so that the first cassette syrup raw material container becomes empty. When the juice is sold after the first bottle is emptied, the raw material in the sub tank is discharged and the liquid level drops. When the liquid level becomes lower than the opening of the lower pipe of the seesaw, the syrup raw material is replenished from the second cassette type syrup raw material container by that amount (see FIG. 4). Thereafter, the above operation is repeated (see FIG. 5) by replacing the empty cassette type syrup raw material container with a new cassette type syrup raw material container.
