Description

[Detailed Description of the Invention] The present invention relates to a tea leaf or raw material tea storage tank having a structure capable of storing tea raw materials, that is, tea leaves, and smoothly supplying tea leaves in a beverage supply device such as a tea dispenser.

In a conventional tea leaf storage tank, in the process of rotation of a cylindrical rotating body having a concave portion for discharging a fixed amount of tea leaves in the tank toward a discharge port, the rotating body and the adjacent tea leaf storage tank are rotated. There were cases where tea leaves were chewed between the tea leaves and the inclined part of the tank, and an excessive load was placed on the tea leaf quantitative supply mechanism. This caused the drive motor that rotates the rotating body to spin idle, caused damage to component parts, and even caused the tea leaves to be crushed into powdered tea.

The present invention was developed to solve the above-mentioned drawbacks, and it prevents tea leaves from being chewed, significantly reduces the load on the tea leaf quantitative supply mechanism, etc., and allows smooth tea leaf supply. To provide a tea leaf storage tank that does not break and can discharge almost no tea leaves in the tank outside the tank.

Next, a preferred embodiment of the tea leaf storage tank of the present invention will be described in detail with reference to the drawings.

In FIG. 1, a tea leaf storage tank (tea raw material storage tank) 12 that stores tea raw materials, which are tea leaves, includes:
In order to allow the tea leaves to fall under their own weight, there is a tank sloped part (wall part) 14 and a tea leaf guide sloped part (wall part) that is connected to this and guides the tea leaves toward the discharge port 17.
16 are provided. At the bottom of the storage tank 12, an arc-shaped tank side wall (wall) 18 is provided that makes surface contact with a cylindrical measuring device (rotary measuring device) 22, and prevents steam from entering from the discharge port 17. ing. A projection 20 is provided between the tank slope 14 and the tea leaf guide slope 16 so as to come into surface contact with the measuring device 22, and the tea leaves are chewed between the projection and the measuring device 22. is prevented. In addition, the tea leaf guide slope part 16 and the tank slope part 1
A step d is provided between the protrusion 20 and the protrusion 20, thereby eliminating the amount of tea leaves remaining at the protrusion 20. In addition, code 23
is the D-shaped micro switch contact part 29 (third
This is the hole that accepts the (Fig.).

In FIG. 2, the weighing device 22 has a metering recess 32 for weighing tea leaves and receiving a fixed amount of tea leaves. The outer circumferential wall 30 of the metering device 22 which is in surface contact with the side wall 18 of the storage tank prevents steam from entering through the outlet 17 and prevents tea leaves from flowing into the outlet 17. The upper part of the tank is sealed with a lid 11.

In FIG. 3, the drive motor 10 is connected to the metering device 22.
It is electrically controlled by a microswitch 28 which drives the tea leaf exchanging device 26 and which is electrically opened and closed by the microswitch contact portion 29 of the metering device.

Upper and lower teeth 26a, 26b of the tea leaf exchange device 26
(FIG. 2) meshes with a gear attached to the rotating shaft of the drive motor 10, and the rotation of the rotating shaft causes the tea leaf exchanging device 26 to move left and right. A tea strainer 24 for receiving tea leaves is attached to a tea leaf exchanging device 26.

Next, the relationship between the measuring device 22 and the tea leaf storage tank 12 will be explained with reference to FIGS. 2 to 5.

In the state shown in FIGS. 2 and 3, the drive motor 10 is stopped and the tea strainer 24 is located at a normal position. At this time, the measuring device 22
The quantitative recess 32 is located in a position where it is closed by the tank side wall 18, and tea leaves from the upper part enter the quantitative recess 32.
It does not invade inside. Outer peripheral wall 30 of the weighing device
is in surface contact with the tank side wall 18 and the protrusion 20, so that steam does not enter the tea leaves in the tank from the outlet 17. The microswitch 28 that electrically controls the drive motor 10 is also opened by the flat portion of the microswitch contact portion 29.

Here, when the drive motor 10 is driven by an electric means such as a reset switch, its rotating shaft begins to rotate clockwise, and the micro switch 28 is closed by the circumferential part of the micro switch contact part 29, and the circuit is connected to the drive motor 10. Start energizing. Drive motor 10
As the rotating shaft further rotates, the tea leaf exchanging device 26 moves to the left as shown in FIG. The tea strainer 24 is inverted. In this way, the tea waste is disposed of in a receptacle (not shown) disposed below the tea strainer 24 at this position. The metering recess 32 of the measuring device 22 rotates clockwise, leaves the tank side wall 18, and flows into the tea leaves from above, filling the metering recess 32 and measuring the tea leaves.

When the drive motor 10 continues to rotate further, the metering recess 32 rotates and moves while being filled with a fixed amount of tea leaves, and the inverted tea strainer 24 is returned to its original state by the tea leaf changing device 26 or the like, and its Move to a position below the discharge port 17 in this state. This state is shown in FIG. At this time, a part of the outer peripheral wall 30 above the metering recess 32 in the measuring device 22 is in contact with the protrusion 20, and tea leaves in the tank are prevented from entering the metering recess 32 which is already filled. At this position, the tea leaves in the quantitative recess 32 have begun to fall toward the discharge port 17 from the lower part of the quantitative recess 32 . When all the tea leaves in the recess 32 have been transferred to the tea strainer 24, the tea leaf exchanging device 26 moves to the left, and the tea strainer 24 attached thereto moves to the regular position shown in FIG. . At this time, the micro switch 28 is opened by the flat part of the micro switch contact part 29, the drive motor 10 is stopped, and the series of tea leaf exchange operations is completed.

In this series of operations, the measuring device outer peripheral wall 30
is in almost continuous contact with the protrusion 20,
Since the protrusion 20 is in contact with the outer circumferential wall 30 to form an obtuse angle, the measuring device 22 rotates smoothly without causing the tea leaves to get caught in the measuring device 22 when it is rotated. In addition, since a step is provided between the tank slope part 14 and the tea leaf guide slope part 16, even if the amount of tea leaves in the storage tank 12 decreases, the tea leaves can be stacked from the protrusion part 20 to the tank slope part 14. Almost all the tea leaves are discharged to the outlet 17 of the tank.
