JPH0362299A - Selling nozzle for cup-type automatic vending machine - Google Patents

Abstract

PURPOSE:To prevent the stay of drink in a selling nozzle and the stay of drops of the drink in a selling port by forming a notch of the prescribed length on the lower surface of the nozzle from its tip. CONSTITUTION:A notch is formed on the lower surface of a selling nozzle 1 from its tip. The drink can be poured from the tip of the nozzle 1 since the drink flows forcibly through a drink supply pipe 9 right after the revolution of a stirring propeller of a mixing ball 6 is stopped. Then the drink never drops from the notch by the action of the surface tension even after the volume of the drink flowing out of th ball 6 is reduced and the flowing force of the drink is reduced. The drink held the notch by the surface tension is moved to the tip of the notch and turned into a ball shape. This ball-shaped drink drops vertically into a cup 13 without moving round the rear surface from the cut surface of the nozzle 1. Thus the drink is completely led into the cup 13 without soiling the side surface of the cup 13.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a cup vending machine that supplies a beverage through a vending nozzle to a cup placed at a vending spout.

(b) Conventional technology In general, with the vending nozzle, while the beverage is being fed vigorously, it is accurately introduced into the cup, but when the beverage feeding operation is nearing the end and the feeding force decreases, the next step is to issues arise.

(1) As shown in FIG. 2, the beverage that has lost its momentum wraps around the surface behind the cut surface of the dispensing nozzle 1 and adheres to the side surface of the cup 2 as dripping.

(2) A turbulent flow is generated at the tip of the vending nozzle 1, and as a result, the beverage that shakes from side to side adheres to the side surface of the cup 2.

Therefore, in order to solve problem (1),
Publication No. 2492 states that on the outer periphery of the tip of the sales nozzle body,
A configuration is disclosed in which a beverage pulling protrusion is provided to convey and attract the beverage whose flow rate has weakened, and the protrusion guides the dripping liquid to a place other than the cup.

In addition, in order to solve problem (2),
Publication No. 83 discloses a structure in which a rectifying rod is provided in a sales nozzle to prevent turbulence.

(c) Problems to be Solved by the Invention However, the above-mentioned conventional technology that solves problem (1) has a new problem in that beverages accumulate in the area where the drinker is led and that area tends to become unsanitary. arise.

Furthermore, the above-mentioned conventional technology that solves problem (2) has a new problem in that beverage remains in the gap between the inner surface of the vending nozzle and the rectifying rod, which also tends to lead to unsanitary conditions.

Therefore, the present invention provides a vending nozzle that reliably introduces drippings into a cup and prevents beverage from remaining inside.

(2) Means for Solving the Problems In order to solve the above problems, the vending nozzle of the cup vending machine according to the present invention has a cut of a predetermined length from the tip on the lower surface of the vending nozzle.

(*) While the beverage is being fed out with force, it flows along the notch and is introduced into the cup, but after the momentum is gone, the beverage tends to accumulate at the tip of the notch due to surface tension, and the accumulated beverage becomes spherical. become. Since the spherical beverage has the notch, it does not wrap around the back surface of the vending nozzle, so it falls vertically and all of the beverage enters the cup, and the dripping does not stain the sides of the cup.

(F) Embodiment Figure 5 shows the configuration of a cup vending machine. 2 is a hot water tank, and water supplied from a water pipe (not shown) is heated by a heater 3 to make hot water. Store in condition. 4
is a hot water pipe, which communicates with the hot water tank 2, opens and closes an electromagnetic valve 5 every time a product is sold, and supplies a predetermined amount of hot water to the mixing bowl 6. Reference numeral 7 denotes a raw material container, which supplies powdered raw materials for a beverage to the mixing bowl 6 via a chute 8. This mixing bowl 6 has a stirring propeller that mixes hot water and powder raw material.

Reference numeral 9 denotes a beverage supply conduit through which a beverage prepared by dissolving powdered raw materials in hot water by stirring in the mixing bowl 6 is passed through the vending nozzle 1 to the cup mounting table 11 of the vending spout 10 and is supported by the cup supporting member 12. Cup 13 placed in the state
supply to. A cup dispenser 14 supplies the cup 13 to the cup mounting table 11 via a cup chute 15.

As shown in FIG. 1, the sales nozzle 1 of the present invention is characterized in that a cut 16 is provided on the lower surface from the tip. In such a vending nozzle 1, since the beverage flows vigorously through the beverage supply pipe 9 immediately after the rotation of the stirring propeller of the mixing bowl 6 stops, the beverage can be dispensed without falling through the notch 16 as shown in FIG. can be poured out from the tip. Even after the amount of beverage flowing out of the mixing bowl 6 decreases and the flow force decreases,
Due to the effect of surface tension, the beverage does not fall from the notches 16 6. Due to the surface tension, the beverage held between the notches 16 moves to the tip of the notch 16 and becomes spherical, and the spherical beverage is As shown in FIG. 4, the sales nozzle 1 falls vertically from the cut surface of the sales nozzle 1 into the cup 13 without going around to the rear surface. Therefore, the last beverage flowing out from the mixing bowl 6 also
Everything is introduced into the cup 13 without staining the side surface of the cup 13 due to dripping.

(G) Effects of the Invention According to the present invention, since all the drinks dispensed towards the end of the vending operation are also introduced into the vending cup, they may remain in the vending nozzle or in the vending spout. A sanitary cup vending machine is provided in which there is no residue left behind, and the sides of the cup are not soiled by the residue, causing discomfort to customers.
