<Purpose of the invention> The present invention focuses on the above-mentioned drawbacks and attempts to provide a beverage supply device that can use viscous liquid raw materials by improving the structure of the raw material supply sections B and C. be.

<Construction of the invention> The beverage dispensing device of the present invention includes a canister main body,
The mixing section is equipped with a cylinder, a piston that is slidably moved within the cylinder by a raw material delivery motor with a speed reducer, a cam, an arm, and a rod bar, and a valve that is always held in a closed state by the biasing force of a spring. The raw material is mixed with water or hot water.

<Example> Hereinafter, a detailed explanation will be given using an example shown in FIG.

The raw material container 16' is a container containing product raw materials, and if it is a hard material that does not deform so that atmospheric pressure and gravity are applied to the raw material, an air hole 39 is provided so that outside air can be taken in. Use a structured container or a soft material such as a plastic bag, and hang it upside down with a hanger or secure it to the canister 17'.
It is installed in a completely sealed state so that there is no leakage. A substantially cylindrical cylinder 40 is provided at the lower part of the canister 17'.
0 includes a piston 4 with packings 41 and 42.
3 is provided. The piston 43 is rotatably driven by a raw material delivery motor 18 with a speed reducer, and is connected to the piston rod 4 via a cam 44, a rod bar 45, and an arm 46.
7 is caused to reciprocate, thereby reciprocatingly slides within the cylinder 40. Further, the driving and stopping of the raw material delivery motor 18 is controlled by the rotation of a cam 44 and the opening and closing of a cam switch 48. The cam 44 and the rod bar 45 are rotatably connected by a pin 49, and the rod bar 45 and the arm 46 by a pin 50, respectively. The arm 46 is rotatably attached to an adjustment plate 53 provided on the main body by a pin 51 and a fixing metal fitting 52, and
2 is movable on the adjustment plate 53 according to the amount of raw material supplied by changing the tightening position of the adjustment screw 54. The arm 46 has an arm groove 5.
5 is bored and fixed with a pin 56 provided on the piston rod 47, and the fixing position can be changed within the arm groove 55 depending on the position of the fixing metal fitting 52, and the rotational movement of the raw material delivery motor 18 is controlled. cam 4
4. Through the rod bar 45 and arm 46, the piston 43 and piston rod 47 can be converted into reciprocating motion. In addition, 57 is an air hole 58
It is a piston cap with a

At the other end of the cylinder 40 is a valve packing 5.
9, a valve 62 consisting of a valve cap 60 and a spring 61 is provided, and when the valve is not in operation, the biasing force of the spring 61 causes the valve packing 59 to close to the cylinder 40.
The opening 63 is closed. Further, the valve gasket 59 is structured to cover the spring 61.

20' is a raw material outlet, 26 is a hot water supply port, and in a mixing part 25', the raw material sent from the raw material outlet 20' and water or hot water supplied from the hot water supply port are mixed and stirred,
A container or the like (not shown) is supplied from the beverage outlet 27'.

The operation of the beverage supply device of the present invention having the above-mentioned configuration and operation will be explained next.

First, as a preparatory work, a raw material container or raw material bag 1
The raw material outlet part 6' is inserted into the raw material inlet part of the canister 17', and the raw material container or raw material bag 16' is hung or fixed upside down on a hanger or the like. As a result, the raw material enters around the piston 43, that is, between the packing 41 and the packing 42, due to atmospheric pressure or gravity.

In this state, drive the raw material carry-out motor 18,
When a trial run is performed, the piston 43 first moves in the direction of arrow A, compressing the air in the cylinder 40 and pressing the valve gasket 59 of the valve 62.
Air inside the cylinder 40 is exhausted from the opening 63. Next, the piston 43 moves in the opposite direction to the arrow A, and in order to create a negative pressure inside the cylinder 40, the raw material enters the cylinder 40 due to atmospheric pressure and gravity, filling the cylinder 40 with air. At this time, the valve 62 is in a closed state. With the above steps, preparation is complete.

Next, normal operation will be explained. First, when you press the start switch (not shown), the hot water supply valve (not shown)
is opened, and water or hot water is supplied in advance to the mixing section 25'. Next, after time t, the raw material discharge motor 18 rotates, causing the cam 44 to rotate. Cam 44 here
A part of the outer periphery is cut out, and when it rotates once, the cam switch 48 is turned OFF and the raw material delivery motor 18 is stopped. The rotational motion of the cam 44 is converted into a reciprocating motion of the piston rod 47 via a rod bar 45 pivotally connected to the cam 44 by a pin 49 and an arm 46 pivotally connected to the rod bar 45 by a pin 50. move. At this time, the packing 41 functions as a valve for extruding and sucking the raw material, and also serves as a seal, and the packing 42 plays the role of sealing to prevent the raw material from leaking from inside the cylinder 40 to the outside. Then, as described above, the piston 43 first moves in the direction of arrow A, presses the raw material filled in the cylinder 40, opens the valve 62, and flows from the opening 63 to the mixing section 25' via the raw material outlet 20'. Send out raw materials. In the mixing section 25', the water or hot water supplied from the hot water supply port 26 and the raw material are mixed and stirred, and the mixture is poured into a container (not shown) from the drinking port 27'. Here, the valve gasket 59 has an opening 63 at its tip.
The valve 62 has a trapezoidal cross section so as to fit into the valve 61 to prevent positional displacement and prevent the valve 62 from opening beyond a certain dimension.The valve 62 is also structured to cover the spring 61 to prevent corrosion of the spring 61. Mixing section 2
Since the space 5' is narrowed and the beverage outlet 27' is narrowed, the raw materials and water or hot water are well mixed and stirred, and are gradually poured out from the beverage outlet 27'. When the supply of raw materials and water or hot water is exhausted and the beverage has been dispensed, the piston 43 moves in the opposite direction of arrow A to replenish the raw materials into the cylinder 40, and the raw material delivery motor 18 stops, and the state is in a standby state. Become.

In the above operation, as shown in FIG. 3, by controlling the operating times of the raw material delivery motor and the hot water supply valve, solubility, delivery performance, and operability are further improved. That is, by first operating the hot water supply valve to supply water or hot water into the mixing section 25', and then driving the raw material delivery motor 18 and supplying the raw material, the solubility is improved and the mixing process is improved. It is also possible to prevent raw materials from adhering to the wall surface of the portion 25'. Here, by changing the closing timing of the hot water supply valve, it is possible to adjust the amount of hot water supplied and freely change the concentration of the beverage. Further, the raw material delivery motor 18 is stopped by a cam switch 48.

In order to adjust the amount of raw material supplied, it is sufficient to change the position of the fixing metal fitting 52. If it is set to the position shown by the broken line in FIG. The amount can be increased and easily adjusted.

<Effects of the invention> As mentioned above, the beverage dispensing device of the present invention is provided with a seal around the outer periphery of the piston, thereby reducing the reciprocating force of the piston required for sucking in and discharging raw materials, resulting in smooth and airtightness. This improves airtightness, ensures reliable operation, allows most raw materials to be transported as long as they are liquids, is not affected by viscosity, and by increasing airtightness, even low-pressure gases can be transported. The cylinder and valve parts are sealed with simple piston caps and valve caps, making them easy to clean. In addition, by using a structure in which the valve is pushed open by the pressing force of the piston, the amount of raw materials can be discharged uniformly and accurately, there is little residual raw material, and it can be discharged reliably. This can be easily done by simply adjusting the position of the metal fittings and the fixing position of the arm and piston rod. Furthermore, by narrowing the space in the mixing section, the raw material can be sufficiently mixed with water or hot water with good force, resulting in many effects such as improved solubility.
