Description

Cup Dispenser of Vending Machine

The present invention relates to a cup dispensing apparatus of a vending machine, and more particularly, to a cup dispensing apparatus of a vending machine, which is capable of dispensing cups of different sizes by changing only the position of the cup discharging cam in one apparatus. will be.

In general, vending machines are devices for diluting raw materials such as powders or concentrates with water and supplying them into separate cups and then selling them as beverages or discharging containers stored therein.

As shown in FIG. 1, the vending machine is provided with a powder raw material container 1 storing powder raw materials therein, a hot water container 2 storing hot water, and a cold water container 3 storing cold water, respectively. On the lower side thereof, there is provided a mixing bowl part 4 which uniformly mixes the powder raw material container 1, the hot water container 2, the powder raw material supplied in the cold water container 3, hot water or cold water, One side of the mixing bowl 4 is provided with a cup dispensing member 6 for supplying a cup 5 for storing the mixed beverage so that the user can drink.

The mixing bowl 4 is configured to mix the powder raw material with hot water or cold water while the stirring blade 8 is rotated in response to the driving of the mixing motor 7.

Therefore, when the user selects a desired beverage, the powder raw material is supplied in the powder raw material container 1, and the hot water or cold water is supplied into the mixing bowl part 4 in the hot water container 2 or the cold water container 3, and the mixing bowl part is supplied. In (4), the stirring blade 8 is rotated by the driving of the mixing motor 7 to uniformly mix the powder raw material and cold or hot water to discharge the beverage into the cup 5 discharged from the cup dispensing member 6. Will be done.

In the cup dispensing apparatus applied to the conventional vending machine, as shown in FIG. 2, the internal gear 9b, which is rotated at a predetermined angle in accordance with the driving of the rotation motor M, is engaged in the lower housing 9a and at the same time. A plurality of cams (9c) for lowering the cup (5) seated on the upper side by engaging with the gear (9b) is rotatably coupled, the upper housing (9d) is configured to be fastened and fixed.

Accordingly, when the cup 9 is rotated while the internal gear 9b is rotated at a predetermined angle in accordance with the driving of the motor M, the cup 5 seated on the upper side of the cam 9c is one by one. By lowering it is possible to discharge the mixed drink water.

However, in the conventional cup dispensing apparatus, when selling hot drinks such as coffee and cold drinks such as carbonated beverages, the sizes of the cups are different, so that the sizes of the cups are different depending on the size of the cups in the separate cup dispensing apparatus. There are many problems inherent, such as the need for gears and cams, which increase the number of parts and increase manufacturing costs.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to produce a cup with a different internal size by one internal gear and cam to minimize the number of parts and at the same time further manufacturing It is to provide a cup dispensing device of a vending machine that can reduce the cost.

The cup dispensing apparatus of the vending machine according to the present invention made to achieve the above object comprises a lower housing, an internal gear seated rotatably in the lower housing, and a cam for discharging the cup as engaged with the internal gear. In the vending machine, the lower housing has inner and outer seating portions formed so that the seating positions of the cams are different depending on the size of the cup, respectively, and the internal gears have small pitch diameters that selectively engage the cams seated at different positions, respectively. And large pitch diameter portions alternately formed.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

3 is an exploded perspective view of the cup dispensing apparatus of the vending machine according to the present invention, wherein reference numeral 10 denotes a lower housing.

An opening 12 is formed at one side of the lower housing 10, a plurality of fastening bosses 14 are formed at an edge thereof, and a seating part 16 in which the internal gear 20 is rotatably seated inside the lower housing 10. And inner and outer seating portions 18a and 18b to which the cam 30 engaged with the internal gear 20 is seated, respectively.

The internal gear 20 is composed of a small pitch diameter portion 22 having a different pitch diameter and a larger pitch diameter portion 24 having a larger pitch diameter than the small pitch diameter portion 22, and alternately repeat each other. It is formed.

The length of the large pitch diameter portion 24 is more preferably formed smaller than the length of the small pitch diameter portion 22 so that the rotation operation of the cam 30 can be made smoothly.

The small and large pitch diameter portions 22 and 24 are respectively engaged with the cams 30 seated on the inner and outer seat portions 18a and 18b, respectively.

The upper housing 40 is detachably fastened by a fastening means such as a bolt on the upper side of the lower housing 10.

The cup dispensing apparatus of the vending machine according to the present invention configured as described above is engaged with the small pitch diameter portion 22 of the internal gear 20 when the internal gear 20 is rotated at a predetermined angle by the driving of a motor (not shown). As the true cam 30 rotates, the cup 5 seated on the upper side is discharged downward.

At this time, the cam 30 is to be rotated in the state seated in the inner seating portion (18a) of the lower housing (10).

Then, when the size of the cup 5 is different, that is, larger than the size of the cam 30 engaged with the small pitch diameter portion 22, the cam 30 seated in the inner seating portion 18a is mounted on the outer seating portion. When settled in 18b, it engages with the large pitch diameter part 24. As shown in FIG.

At this time, when the internal gear 20 rotates at a predetermined angle according to the driving of the motor, the cam 30 meshed with the large pitch diameter portion 24 rotates and the large cup 5 seated on the upper side is lowered. Will be thrown out.

Accordingly, the cams 30 having the same size are selectively engaged with the small and large pitch diameter portions 22 and 24 of the internal gear 20, respectively, to rotate the cups 5 having different sizes. It becomes possible.

As described above, in the cup dispensing apparatus of the vending machine according to the present invention, a cup having a different size can be dispensed by a cam that is selectively engaged with one internal gear, thereby minimizing the number of parts and at the same time manufacturing costs. There are several effects, such as saving money.
