Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cup-type beverage vending machine that prepares and sells beverages by mixing powdered raw materials with hot or water.

[Conventional technology]

First, FIG. 1 shows a conventional beverage system diagram of the cup-type beverage vending machine mentioned above. In the figure, 1 is a raw material box with a raw material delivery mechanism, 2 is a potable water tank containing hot water or water (the hot water tank shown), 3 is a raw material shooter placed facing the raw material export port of the raw material box 1, and 4 6 is a mixing agitator that mixes the powdered raw material carried out from the raw material box 1 and hot water supplied from the hot water tank 2 via the hot water supply valve 5; 6 is its stirring motor;
Reference numeral 7 denotes a beverage supply pipe installed between the mixing agitator 5 and the bending stage 8, 9 a tip nozzle of the pipe, and 10 a cup conveyed to the bending stage 8 from a cup mechanism (not shown). Among the raw material boxes 1 described above, the raw material boxes denoted by symbols A to G store, for example, cocoa, youth, black tea, lemon, coffee, sugar, and cream, respectively, in order from the left. If, for example, milk or sugar-containing coffee is selected at the time of sale, a predetermined amount of powdered raw material is transported to the common computer 3 from the designated E, F, and G raw material boxes 1. and falls into the mixing agitator 4. On the other hand, a hot water supply valve 5 leading from the tank 2 to the agitator
is opened to supply hot water, and here the powdered raw materials of coffee, sugar, and milk are mixed with the hot water to prepare coffee containing sugar and milk, and from here, the beverage is supplied to the cup 10 via the beverage pipe 7. .

[Problem to be solved by the invention]

By the way, as mentioned above, the raw material boxes are divided into groups based on the powdered raw materials that are mixed together for each type of beverage, such as coffee and tea, and the common shooter and mixer are assigned to each group to produce each system of beverages. In the conventional machine that is configured as a line, the combinations of various raw materials are fixed in advance, and it is not possible to respond to requests for selection between different beverage systems, such as black tea with milk, as shown in FIG. 1, for example. Furthermore, even if it were possible to select raw materials for tea and milk separately and transport the raw materials from each raw material box C and G, if the configuration of the conventional machine remains unchanged, raw material box G for milk would be handled by the coffee group. Because it belongs to a production line, even if only the milk is carried out separately, the flavor, aroma, and color of the coffee remaining in the brewer, stirrer, etc. will be transferred to the milk that is carried out. A defect occurs that impairs quality. Furthermore, within each group for coffee, tea, etc., multiple raw material boxes are associated with one common shooter, so within the same group, each raw material box must be placed adjacent to each other. This places restrictions on the layout of the raw material boxes inside the machine. In other words, in conventional machines, although the machine is equipped with multiple types of ingredient boxes, the combination of ingredients is fixed in advance depending on the type of beverage.
Even if an arbitrary combination of raw materials is required for different types of beverages, this cannot be met.

On the other hand, recently, with the diversification of beverages, new types of powder raw materials have been developed one after another, but the conventional machines mentioned above can flexibly respond to changes in powder raw materials, changes in the blending combination of raw materials, etc. Therefore, the arrangement of the shutter, mixer, etc. must be rearranged each time.

This invention was made in consideration of the above points, and it is a powder raw material that enables the preparation of various beverages by combining various raw materials in various ways without changing the layout in the machine between multiple types of powder raw materials. The purpose is to provide a highly versatile cup-type beverage vending machine that can respond to diversification.

[Means to solve the problem]

This invention comprises an independent beverage production line in which each raw material box passes through a raw material shooter between the raw material box and the bend stage, and a mixing agitator for mixing powdered raw materials and hot water supplied from a tank. an input means for selecting a beverage, a setting input means for presetting a combination of raw materials to be prepared for each type of beverage, an amount of raw materials and hot water for one drink, and an input signal for selecting the beverage. a control processing means for outputting operation signals for transporting raw materials, hot water and a mixing agitator to a designated beverage production line according to setting conditions determined by a setting input means; and based on an output signal from the control processing means. It is inserted into the circuit corresponding to each group of the beverage production line, which is grouped by the type of raw materials, to control the operation of the raw material box, hot water supply valve, and mixing stirrer of the beverage production line specified by the method. a common relay contact, an individual relay contact that is individually inserted into a circuit corresponding to the beverage production line for each raw material, and the common relay contact and the individual relay contact.
This is achieved by a driving means constituted by a relay circuit consisting of an AND circuit and a relay circuit.

[Effect]

According to this invention, at the time of sale, the beverage production line designated by the control command based on the beverage selection is individually operated, and one or more types of powder raw materials are individually mixed with a predetermined amount of hot water within the production line. A single drink made by mixing is discharged and supplied into a cup placed on a bend stage, and mixed in the cup to make a desired drink.
