Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raw material supply device for a ready-to-drink beverage vending machine that takes out beverage raw materials from a beverage tank at the time of sale, dilutes them with a diluent such as hot water in a mixing bowl, and then sells the beverage raw materials. This particularly relates to the improvement of raw material supply equipment.

By the way, if we look at the conventional raw material supply device of such a vending machine, as shown in Fig. 1, there is a spiral spiral rotatably driven by a supply motor (not shown) at the lower end of a raw material tank 1 called a canister. A blade 2 is provided, and the canister nozzle 3 is driven by the timed drive of the spiral blade 2.
It had a structure that supplied a more appropriate amount of raw materials.

For this reason, in such a conventional device, the structure of the lower end of the raw material tank 1 cannot be complicated, and since the raw material is carried out and supplied using a spiral blade, the driving time of the spiral blade is shortened. However, even if the drive time were to be constant, the feed rate of raw materials would not be constant due to voltage fluctuations or other conditions, and as a result, the taste would be different each time it was sold. Was.

The present invention was invented based on the drawbacks of the conventional equipment, and it uses its own natural falling blade to store the raw material from the raw material tank in the metering space and supplies it at all times. This system is characterized by being able to supply a fixed amount of raw material and automatically preparing for the next operation after supplying the fixed amount of raw material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.

The valve plate 18 of the drain valve 12 is supported by the protrusion 17 in this supported state.
The mixing device C is connected to the connecting pipe 15 that constitutes the support part 16 that lifts up against the spring 19 to open the valve port 20, and the mixing device It is comprised of a hot water supply vibrator 21 that extends to a mixing bowl, which will be described later.

In the hot water tank 13, what is designated by the reference numeral 23 is a partition plate, which is a cylinder that stands upright at the center of the bottom of the hot water tank 13, and forms a preheating chamber 24 therein.

That is, the water led from the water storage tank 11 through the connecting vibrator 15 enters the bottom of the preheating chamber 24, where it is preheated by the heater 14, and then flows to the top of the preheating chamber 24 as shown by arrow a. The water flows between the water storage tank 11 and the partition plate 23.

Therefore, the hot water between the water storage tank 11 and the partition plate 23 is not rapidly cooled by new water introduced from the water storage tank 11, so that hot water at an appropriate temperature can always be supplied to the mixing device. . Next is the mixing device C, which is made up of upper and lower components 26 and 27 that are removably screwed together at a centrally reinforcing portion, and is configured to mix hot water supplied through the hot water supply vibrator 22 with a raw material vibrator, which will be described later.

This coating 34 is provided with a perforation line 35 indicated by a dotted line, and by cutting the coating 34 along this perforation line 35, a fan-shaped raw material outlet 36 is formed. Further, 37 is constructed by providing a hollow support protrusion 38 in the center of a disc whose diameter is smaller than the inner diameter of the raw material tank 33 by the thickness of the coating 34, and opening a sector-shaped first raw material port 39 on the plate surface. The raw material tank 33
It is designed to be fitted onto the end surface on which the coating 34 is applied.

Further, reference numeral 40 designates a lid member consisting of a short cylindrical body with a bottom having an inner diameter that is approximately the same as the outer diameter of the raw material tank 33, and the bottom surface of the lid member is aligned with the raw material outlet 36 and the first raw material port 39. A fan-shaped second raw material port 41 is provided at the center of the bottom surface for supporting the support projection 38 of the rotary plate 37, and a locking projection 43 is provided on the outer surface of the bottom surface. In both cases, a positioning protrusion 44 is provided in the center.

The lid member 40 is fitted onto the end surface of the raw material tank 33 with the rotary plate 37 fitted therein, since it is difficult for the bottom surface to make surface contact with the rotary plate 37 in this fitted state. , a ring-shaped support protrusion 45 is provided on the inner surface of the bottom surface.

Further, reference numeral 46 is a base fixed to a support plate 62 inside the machine, and has a fitting part 47 on the top surface into which the lid member 40 can be fitted, and a through hole 48 is provided in the center. 48
A third raw material port 49 that can match the raw material outlet 36 etc. is provided on the outer side, and a locking hole 50 that engages with the locking protrusions 43, 43 of the lid member 40 on the bottom surface of the fitting part 47. It is constructed by providing the following.

Further, reference numeral 51 has a flange 52 on the upper periphery of the disc material, and an engagement hole 53 on the lower surface of the center of the plate surface.
A second rotary plate configured by providing a raw material outlet 54 that can match the raw material outlet 36 etc. on the outside of the base 46, and a mounting bracket 55 that is attached to the lower surface of the base 46 by screw means. By engaging the collar 52, the first rotary plate 37 is rotatably supported on the lower surface of the base 46, and a transmission shaft 56 protruding from the upper surface of the center of the plate surface passes through the through hole 48 of the base 46. The engagement hole 3 drilled in the support protrusion 38 of
", the rotational force of the second rotary plate 51 is applied to the first rotary plate 37.
It is designed to communicate to people.

Further, the upper end of 57 is engaged with the engagement hole 53 of the second rotary plate 51, and the lower end is connected to the raw material supply motor 59 via the transmission means 58.
The motor 59 is configured to have a drive shaft connected to the motor 59 and apply the driving force of the motor 59 to the first and second rotary plates 37 and 51.

Further, 60 has a lower end facing into the mixing bowl 25 of the mixing device C, and an upper end approximately facing the lower surface of the second rotary plate 51 at a position facing the third raw material port 49 of the base 46. This is a raw material supplying vibrator that is installed so that the two parts are in contact with each other.

Note that 61 is a bearing that allows the second rotary plate 51 to rotate smoothly. The constituent members of the beverage raw material supply device C are as described above, and in such a device, the raw material tank 33
A large number of containers containing beverage raw materials and sealed with a coating 34 are prepared in advance, and if necessary, one of the coatings 34 of the raw material tank is cut out along the cutting line 35 to open the raw material outlet 36.
At the same time as opening the first rotary plate 37, the first raw material port 3 is opened.
9 is 90 in the counterclockwise direction from the raw material outlet 36.
The coating 3 is placed on the end face of the raw material tank 33 so as to be in the above position.
4, and furthermore, the lid member 40 is fitted onto the end face of the raw material tank 33 on the side where the first rotary plate 37 is fitted, so that the second raw material port 41 thereof coincides with the raw material outlet 36 of the coating 34. After fitting in such a manner (see step (1) in FIG. 5), the raw material tank 33 is inverted and placed on the fitting part 47 of the base 46 via the lid member 40. , it becomes possible to supply a fixed quantity of beverage raw materials, and it also becomes possible to use the raw material tank as a spare.

At this time, the engagement hole 38'' of the first rotating plate 34 is engaged with the upper end of the transmission shaft 56.

Also, in this way, the raw material tank 33 is connected to the fitting part 47 of the base 46.
In the unoperated state immediately after setting the
As shown in (2), the raw material outlet 36, the second raw material port 41,
and the third raw material port 49 are relatively aligned, and the first
The raw material outlet 39 and the raw material outlet 54 are respectively shifted from the three ports 36, 41, 49 as shown in the figure, and in particular,
Since the first raw material port 39 of the first rotary plate 37 is misaligned with the raw material outlet 36, the raw material in the raw material tank 33 has not yet come out.

Since the present invention is constructed as described above, its operation will be explained below.

Now, as described above, attach the raw material tank 33 to the fitting part 4 of the base 46.
When a sales signal is output by inserting a coin or the like in the raw material supply waiting state (step (■) in FIGS. 2 and 5) placed on 7, the raw material supply motor 59 is driven. The driving force is transmitted to the second rotary plate 51 through the transmission means 58 and the drive shaft 57, and is also transmitted to the first rotary plate 37 through the transmission shaft 56.

As a result of this power transmission, both the rotary plates 37 and 51 begin to rotate counterclockwise, and after 905 rotations each, the second rotary plate located at the lowest end as shown in FIG. Except for the raw material outlet 54 of the rotary plate 51, the first rotary plate 3
7, the first raw material port 39 is the raw material outlet 36, and the second raw material port 4
1, and the third raw material port 49, so the raw material tank 3
The raw material in 3 is dropped and carried out through the raw material outlet 36 and the first raw material port 39 to the second and third raw material ports 41 and 49.

In this state, the lower end of the third raw material port 49 is connected to the second rotating plate 51.
Since the port 49 is closed, the raw material in the port 49 is momentarily retained within the port 49. When the rotation of the first and second rotary plates 37 and 51 advances further from this state, and reaches a state where the rotation has advanced by 900 degrees from (■) as shown in FIG. 5 (■),
The first raw material port 39 of the first rotary plate 37 is the raw material outlet 36
, the first rotary plate 37 closes the raw material outlet 36 so that the second and third raw material ports 41 and 49 do not match, and the raw material outlet 54 coincides with the second and third raw material ports 41 and 49. Therefore, the raw materials in these ports 41 and 49 that have been held until then are supplied to the mixing bowl 25 through the raw material outlet 54 and the raw material supply vibrator 60. On the other hand, since the mixing bowl 25 is supplied with an appropriate amount of hot water from the hot water tank 13 through the hot water supply vibrator 21 by opening the solenoid valve 22 in accordance with the timing of this raw material supply, these raw materials and hot water are At the right timing, the mixing blade 30 drives the mixing motor 31 to mix the water, and the water is poured into the cup F from the pouring vibrator 28 to become suitable drinking water.

Also, while the raw materials are being supplied and being mixed with hot water and poured into the cup F, the first and second rotary plates 37, 51 are successively rotated,
At the timing of further 180 rotations from the state shown in the figure (■), the machine enters the original raw material supply waiting state shown in FIG. 5 (■) and stops.

That is, the raw material supply motor 59 starts driving at θ based on the input of the sales signal, and stops driving at the timing when each rotary plate 37, 51 has rotated exactly one rotation. From then on, such operations are repeated every time the sales signal, etc. is input, but when the supply of raw materials progresses and there are no more raw materials in the raw material tank 33, the operator must remove the empty raw materials. Remove the tank 33 together with the lid member 40 from the base 46, and replace it with a new raw material tank 33 by attaching it to the fitting part 4 of the base 46 with the raw material outlet 36 of the coating 34 open.
7 and prepare for the next sale. Of course, on the end surface of the new raw material tank 33 on the coating 34 side, the first rotary plate and the lid member removed from the empty old raw material tank 33 have respective openings 39 and 41 as shown in FIG. 5 (1). Needless to say, it will be addressed in such a way that it will be in the same state as before.

Although not mentioned in the above description, the reference numeral 63 designates an exhaust vibrator with one end facing inside the mixing bowl 25 and a blower 64 at the other end. The drive exhausts the water vapor generated in the mixing bowl 25 during mixing, prevents the water vapor from entering the raw material supply vibrator 60, and also exerts its suction force inside the raw material supply vibrator 60 to This prevents the raw material from adhering to the inner wall of 60.

Further, in the above practical example, the second raw material port 41 of the lid member and the third raw material port 49 of the base 46 form a metering port that keeps the amount of raw material supplied at one time constant, Therefore, the amount of raw material supplied can be changed by appropriately changing the volume of this metering port.

Of course, in this case, if the first rotating plate 37 rotates too fast,
Since a sufficient amount of raw material is not dropped from the raw material tank 33 into the metering port, it is necessary to select an appropriate driving speed of the raw material supply motor. As described above, the present invention provides a base having a raw material port forming a metering space for storing raw materials for one batch, and a base that is rotatable above and below the base and has at least the raw material port. A first rotating plate and a second rotary plate each having a raw material outlet or a raw material discharging port formed in such a positional relationship that when either the upper or lower end opening is closed, the other is opened.
A rotary plate, a drive source for driving the first rotary plate and the second rotary plate, and a drive source that is detachable from the first rotary plate and has a raw material outlet relative to the raw material port of the first rotary plate. Since it is equipped with a formed raw material tank, there is no need to worry about various conditions such as the drive time setting of the raw material feeding means and voltage fluctuations, unlike in the past, and the structure is extremely simple, and it is always accurate. In addition to being able to supply a certain amount of raw material to the tank, it is also possible to automatically prepare for the next operation due to the mutual relationship between the first rotary plate, the second rotary plate, and the base. Since it has a structure that can be attached to and removed from the single-rotation plate, it is extremely easy for the operator to replace the raw material tank, and there are fewer malfunctions, which is advantageous in terms of space, and the entire device is designed to be small and compact. It can have many remarkable effects.
