JPH01142894A - Door opening-closing mechanism for food vending machine - Google Patents

Abstract

PURPOSE: To prevent food or drink from dripping afterwards and a nozzle from being touched directly with a hand by closing a 2nd door when a 1st door is opened and opening the 2nd door when the 1st door is closed. CONSTITUTION: A shaft 14 is driven by a driving source and the 1st door 2 moves clockwise to close the opening 1b in the front of a case 1. The upper end of a shaft 9 stood on the 2nd door 6 is fitted in the long hole 11 of an arm 3a, so the arm 3a rotates and the 2nd door 6 rotates clockwise on a support shaft 8 to open the upper opening of the case 1. Then the drink and ice are supplied from a nozzle 12 and an ice chute 13 into a cup la by specific amounts. The shaft 14 reverses and the 1st door 2 moves again to open the front opening 1b of the case 1, so that the 2nd door 6 closes the upper opening associatively with the said operations. Consequently, the drink or food is prevented from dripping afterwards and those supply openings are never touched with the hand.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates primarily to a vending machine that supplies solid or liquid food materials to cups and sells them.

(B) Conventional technology Traditionally, vending machines that sell food and beverages in cups are equipped with a beverage supply nozzle, ice chute, impeller (stirring blade), etc. above the cup installation chamber, and also have a cup ejector. A door is provided to open and close the mouth, and the door is closed when the material is supplied to the cup, and when the supply is finished, the door is opened and the cup is taken out.

(c) Problems to be Solved by the Invention However, in such vending machines, there are nozzles and ice chutes for feeding food and drinks above the cup installation area, so after the supply is finished, However, there is a problem in that material adhering to the nozzle or chute drips down, resulting in so-called "drip" and staining the user's hands and the place where the cup is installed. In addition, these nozzles and chutes can be touched directly from the cup outlet, and if something like a poison gets on them,
There are sanitary issues that can be life-threatening.

This invention was made in consideration of these circumstances,
To provide a safe and sanitary door opening/closing mechanism for a vending machine that prevents food and drinks from dripping and is configured so that nozzles and chute cannot be directly touched from a cup outlet.

(d) Means for Solving the Problems This invention provides solid and/or
Alternatively, a supply nozzle for supplying liquid food material is provided, and when a cup is installed in the installation chamber, the food material is supplied from the nozzle to the cup through the top opening of the installation chamber, and the cup is removed from the front opening of the installation chamber. In a food vending machine configured to be able to take out a cup, the arm is rotatably supported on a first fulcrum provided outside the upper part of the cup installation chamber, and the second arm is fixed to the arm and opens and closes the front opening of the cup installation chamber. It is rotatably supported by a first door and a second fulcrum provided outside the upper part of the installation chamber, and is connected to the arm to open and close the top opening of the installation chamber in conjunction with the operation of the first door. Equipped with a second door, the second! This door opening/closing mechanism for a food vending machine is characterized in that the second door closes when the door opens, and the second door opens when the first door closes.

(e) When the cup is installed in the action installation chamber, the first door closes and the second
The door opens and ingredients are fed into the cup.

When the supply ends and the first door opens, the second door is closed in conjunction with this. Therefore, the dripping of the food material is blocked by the second door, and the second door is always closed when the first door is open, so the material supply port is not touched from the cup takeout port. , hygienic.

(f) Examples The present invention will now be described in detail based on examples shown in the drawings. This invention is not limited by this.

FIG. 1 is a front view showing one embodiment of the present invention, FIG. 2 is a top view of FIG. 1, and FIG. 3 is an explanatory diagram of the operation of FIG. 2. In these figures, l is the case of the installation chamber in which the cup la is installed, and 2 is the part that opens and closes the opening (cup ejection port) Ib on the front of the case. 3a and 3b are arms that support the first door 2; 4 is a bracket fixed to the top surface of the case; 5 is a rotating shaft that rotatably supports the arm 3a;
6 is a second door that opens and closes the opening 1c (FIG. 3) on the top surface of the case l; 7 is a support shaft 8 of the second door 6 provided on the top surface of the case 1;
(Fig. 2); 9 is a shaft provided upright on the second door 6; 10 is a roller rotatably provided at the upper end of the shaft 9; 11 is provided in the arm 3a, and the roller 10 is 12 is a beverage supply nozzle, 13 is an ice chute, 14 is a shaft provided on the arm 3b coaxially with the rotating shaft 5, and the shaft 14 is connected to a drive source and is connected to the first door 2. Rotates when opening and closing.

In such a configuration, when a charge is placed in the vending machine and a desired beverage is set, the shaft 14 is rotated by the drive source, and the first door 2 shown in FIG. 2 is opened as shown in FIG. 3. Move clockwise to open the front opening 1b of case l.
Close. At this time, since the roller lO at the upper end of the shaft 9 installed upright in the second door 6 is fitted into the elongated hole 11 of the arm 3a, the arm 3a shown in FIG. 2 rotates to the position shown in FIG. 3. , whereby the second door 6 rotates clockwise about the support shaft 8 to open the upper opening 15 of the case l. Next, a predetermined amount of beverage and ice are supplied into the cup 1λ from the nozzle 12 and the ice chute 13. When these supply operations are completed, the shaft L4 rotates in the opposite direction, the first door 2 moves again to the position shown in FIG. 2, and the front opening tb of the case l is opened. In conjunction with this operation, the second
A door 6 closes the opening 1c. Therefore, the dripping from the nozzle 12 and the shoe 13 is blocked by the second door 6 as shown in FIG. Furthermore, when the opening 1b at the front of the case is open, the opening 15 at the top of the case l is closed, so the nozzle 12 and the chute 13 cannot be touched from the outside.

In this way, a door opening/closing mechanism for a vending machine is provided that prevents food and beverages from being left behind and prevents the supply opening from being touched by hand.

(g) Effects of the Invention According to this invention, not only is it possible to prevent food and beverages from being contaminated, but also the nozzles and stirring blades that supply them are not directly touched by hands, making them safe and sanitary. Food vending machines will be provided.
