Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic tea leaf feeding device for an automatic tea dispenser for green tea, black tea, etc.

BACKGROUND OF THE INVENTION A tea leaf feeding device that automatically feeds tea leaves into a tea strainer and a part of a filter has been known, for example, in Japanese Utility Model Publication No. 60-10508.
It is shown in the publication No. The contents will be explained here. The device described in Japanese Utility Model Publication No. 60-10508 consists of a tea caddy that stores tea leaves and a rotating drum with a recess that supplies a certain amount of tea leaves to a tea strainer filter. The purpose is to supply the tea to the tea strainer filter according to the following.

Problems to be Solved by the Invention However, in the conventional configuration as described above, the size of the opening of the recess is limited because the rotating drum cannot be made infinitely large. When this happens, the opening of the recess becomes clogged with tea leaves, which prevents a sufficient supply of tea leaves to the tea strainer and filter, resulting in insufficient tea extraction and a bad taste.

In view of the above-mentioned problems, the present invention provides a tea leaf supply device that can reliably strain and supply tea leaves to a filter even if the tea leaves have many stems.

Above are the means to solve the problem! In order to solve one problem, the tea leaf supply device of the present invention includes a tea caddy for storing tea leaves, a hollow cylindrical casing which is connected to the tea caddy at one end below the tea caddy and has an open opening at the other end, and a predetermined container inside the casing. A worm pin auger is inserted with a clearance and fixed by a yoke part and a shaft provided on the outside of the casing, and a thin shaft is installed in a part of the casing so as to be rotatable, and the opening opening is opened and closed. a shutter, an arc-shaped engagement part provided on a part of the shutter, a tea strainer filter part located below the shutter and having an automatic reversing function, and a drive provided to be connected to the yoke part. A gear, an interlocking gear meshing with the drive gear and connected to a drive motor, a shaft fixed to the interlocking gear and provided to move in contact with an arc-shaped engagement portion provided on a part of the shutter, and a drive gear. , a guard box consisting of interlocking gears, and a drive motor.

With this configuration, when the tea strainer filter receives a tea leaf replacement instruction signal, the tea strainer filter is turned over from its normal horizontal position by the automatic reversing function, and the old tea leaves in the tea strainer filter are discarded. After the tea strainer filter returns to its normal horizontal position, new tea leaves are supplied. At this time, the drive motor rotates, and the interlocking gear and drive gear also rotate. The rotation of the drive gear rotates the auger via the yoke. The tea leaves stored in the tea caddy are collected at the open mouth of the casing by the auger rotation conveyance operation. The open opening is such that the shutter is closed by the force of a spring attached to the shutter. When a certain amount of tea leaves accumulates in the open mouth, the shaft fixed to the interlocking gear touches the arc-shaped engagement part provided on a part of the shutter and moves upwards, forcing the shutter to close as the shaft rotates. Since the shutter is designed to be open, new tea leaves can be reliably supplied to the tea strainer filter along the shutter.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of the configuration of an automatic tea leaf feeding device in an embodiment of the present invention. The second section is a section taken along the line A--A in FIG. 1, FIG. 3 is a schematic diagram of the tea leaf supplying operation in the embodiment, and FIG. 4 is a schematic diagram of the tea leaf supplying operation in the embodiment.

1 is a tea caddy, 2 is a casing connected to the tea caddy, 3 is an open opening provided in the casing, 4 is a worm-shaped auger inserted into the casing with a predetermined clearance,
5 is a yoke portion that is directly connected to the auger by a shaft; 6 is a shutter 7 that is attached to the outer shell of the casing using a thin shaft and extends over the open mouth portion 3; 8 is a spring that is attached between the thin shaft and the shutter 6; 9 is a guard box, and 9 is a drive gear provided in the guard box 8, which is installed so as to be concentrically joined to the yoke portion 5. Reference numeral 10 denotes an interlocking gear provided in the guard box, which is installed so as to mesh with the drive gear 9. A drive motor 11 is directly connected to the interlocking gear 10 and fixed to the guard box 8. 12 is a shaft fixed to the interlocking gear 10; 13 is a circular engagement portion 5'R provided in a part of the shutter 6; the shaft 12 is in contact with the arc-shaped engagement portion 13 of the shutter 6 and extends along the arc; Go for a walk. Reference numeral 14 denotes a tea strainer filter, which is installed so that the shutter 6 is positioned downward when it is opened.

The operation of the automatic tea leaf exchanger configured as described above will be explained below. 6 During normal use, the tea strainer filter 14 is held in the normal horizontal position as shown in FIGS. 1 and 2. .

Tea leaves are placed in the tea strainer filter 14, and tea is extracted by pouring the tea leaves into the tea strainer filter 14. When a predetermined amount of tea is extracted, the tea leaves become sludgy, so if you set it so that a tea leaf replacement instruction signal is issued when a preset amount of tea is extracted, the tea leaf replacement instruction signal will be activated when the preset amount is reached. First, the tea strainer filter 14 is turned over by an automatic reversing function, and the tea leaves are discarded. When the tea strainer filter 14 returns to its normal horizontal position, new tea leaves will be supplied.

At this time, the drive motor 11 rotates, and the interlocking gear 10 and the drive 1
! 1$9 also rotates. The rotation of the drive tooth $9 causes the auger 4 to rotate via the yoke portion 5. The tea leaves stored in the tea caddy 1 are collected in the open mouth 3 of the casing 2 by the rotational conveyance operation of the auger 4. The open opening 3 is configured so that the shutter 6 is closed by the force of a spring 7 attached to the shutter 6. When a certain amount of tea leaves has accumulated in the opening 81S3, the shaft 12 fixed to the interlocking gear 10 comes into contact with the arc-shaped engagement part 13 provided in a part of the shutter 6 and moves on it. Since the shutter 6 is forcibly opened as it rotates, new tea leaves can be reliably supplied to the tea strainer filter 14 along the shutter 6.

Effects of the Invention As described above, the present invention provides a tea caddy for storing tea M, a hollow cylindrical casing which is connected to the tea caddy at one end below the tea caddy and has an open opening at the other end, and a hollow cylindrical casing having a predetermined clearance inside the casing. a worm-shaped auger that is inserted and fixed by a yoke portion and a shaft provided on the outside of the casing; and a shutter that is installed in a part of the casing so as to be rotatable by a thin shaft and opens and closes the opening portion. and an arc-shaped engagement portion provided in a part of the shutter,

An automatic tea dispenser equipped with a guard box consisting of a shaft, a drive gear, an interlocking gear, and a drive motor, the shaft being fixed to the shutter and movable in contact with an arc-shaped engagement part provided in a part of the shutter. With this tea leaf feeding device, the opening area of the contact area between the tea caddy and the casing can be equal to or larger than the M diameter of the auger8, so even if tea leaves with many stems are put into the tea caddy, there will be no contact area at the connection part. Tea leaves do not get clogged, and therefore commercially available tea leaves can be used without preparing tea 11 especially for an automatic tea dispenser.

Furthermore, since the tea leaves are not clogged in the conveying section due to the twisting conveyance by the auger, the tea leaves can be supplied reliably.
