Description

The present invention relates to a kneading machine that has been used in tea factories for a long time.

In recent years, as an alternative to traditional kneading, a rotor van kneading machine that kneads with a screw, a CTC kneading machine that cuts tea leaves with a roller, and the like have been used. However, many orthodox type kneading machines that put tea leaves in a cylindrical drum that rotates on a kneading board and pressurize the tea leaves with a pressure lid are still used.

As the orthodox type kneading machine, the one shown in Patent Document 1 in which a gate form is passed above the cylindrical drum and a pressure rod with a pressure cover at the tip is attached to the gate form.
A rod (horizontal girder), one of which is supported by a support, is passed above the cylindrical drum shown in Patent Document 2, a weight that can be moved on the rod is provided, and a pressure rod with a pressure lid is attached to the center of the rod. The former is used for black tea production and the latter is used for green tea production.

Japanese Unexamined Patent Publication No. 2011-200186 Japanese Unexamined Patent Publication No. 10-56968

Each orthodox kneading machine has a long history, but the basic structure has hardly changed.

The one provided with the gate formwork shown in Patent Document 1 has a complicated structure and is difficult to operate, and the gate formwork becomes an obstacle when tea leaves are put into a cylindrical drum. In addition, since the operation mechanism of the pressure rod pops out high on the gate formwork, the installation space must be high.

In the case where the weight is placed on the cross girder on the cylindrical drum shown in Patent Document 2, the weight is unstable and dangerous, and it is difficult to increase the pressing force. Since the pressure rod moves up and down in an arc with one of the cross girders as a fulcrum, the movement of the pressure lid up and down does not become a straight line, and the movement distance cannot be increased.

In claim 1, in order to solve the above problem,
A strut provided on the outside of the cylindrical drum is made expandable, a pressure lid holding arm is extended from the strut to the vicinity of the central axis of the cylindrical drum, and a pressure rod with a pressure lid at the lower end near the tip of the holding arm. Use the means of mounting.
Further, in claim 2,
The telescopic column is composed of a fixed guide column and a vertically moving column, a pressure lid holding arm is attached to the upper end of the vertically moving column, and the vertically moving column is moved up and down by an air cylinder.
Further, in claim 3,
A means is used in which the pressure rod extending upward from the center of the pressure lid and the attachment portion of the pressure lid holding arm are made into a universal joint.

By providing the support on the outside of the cylindrical drum, the gate form as seen in the example of Patent Document 1 becomes unnecessary, and the tea leaves can be easily put in.
In order to make this column expandable and contractible, it is composed of a fixed guide column and a vertically moving column, a pressure lid holding arm is provided at the upper end of the vertically moving column, and a pressure rod with a pressure lid is attached to the tip of the column to move up and down. The structure that raises and lowers the moving pillar with an air cylinder, raises and lowers the pressure lid, and pressurizes the tea leaves simplifies the pressure mechanism. If the cylinder is provided in the column portion, it is not necessary to extend the pressurizing mechanism upward, and the installation space can be lowered.
Further, unlike the example of Patent Document 2, a cross girder and a weight are not required, which makes it simple and safe.
Since the pressure lid is up and down in the vertical direction, the movement distance can be long.

The plan view of the tea leaf kneading machine which shows the Example of this invention. The side view of the tea leaf kneading machine of FIG. 1, and the inside of the cylindrical drum show the cross section.

Examples of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a kneading machine of an orthodox type kneading machine, and a cylindrical drum 2 is supported by cranks 3, 4, and 5 to rotate on the upper surface of the kneading machine 1. A pressure lid 6 is provided in the cylindrical drum 2, and is attached to the tip of the pressure lid holding arm 8 by a pressure rod 7.
A universal joint 9 is used for the mounting portion. The pressure lid 6 is made smaller than the cylindrical drum 2 and a gap 11 is provided in order to put in the tea leaves. Therefore, the pressure rod 7 swings left and right due to the movement of the cylindrical drum. The universal joint 9 absorbs this runout. The universal joint 9 includes a ball joint, a cross joint, and the like.
The pressure lid holding arm 8 is attached to the vertical movement column 12 and moves up and down together. The vertical movement pillar 12 is connected to the lot 16 of the air cylinder 15, and moves up and down along the fixed guide pillar 14. The fixed guide pillar 14 stands on the rear arm 13 of the cylindrical drum 2 and contains an air cylinder 15.

Next, the operation of this embodiment will be described.
Initially, when the pressure of the air cylinder 15 is set to zero, the pressure lid 6 hangs at the lower end position by its own weight.
When the tea leaves are thrown in little by little from the top of the cylindrical drum 2, they slide down along the pressure lid cover 17 and collect on the kneading board 1 through the gap 11.
Due to the movement of the cylindrical drum 2, the tea leaves enter under the pressure lid 6 and gather in the center of the kneading board 1 to form a mass of tea leaves 10 and push up the pressure lid 6. When a certain amount of tea leaves are charged, the pressure lid 6 is pushed down by the air cylinder 15 to pressurize the tea leaf mass 10. The tea leaf mass 10 sandwiched between the kneading board 1 and the pressure lid 6 is subjected to a kneading action by the rotation of the cylindrical drum 2.
When the tea leaves are charged at one time, the pressure lid 6 is pulled up to the top of the cylindrical drum 2 by the air cylinder 15, and the tea leaves are charged from the top of the cylindrical drum 2.
