Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a rolling hand cover for a tea manufacturing machine such as a tea rough rolling machine or a medium rolling machine used for stirring and kneading tea leaves in the tea manufacturing process.

<Prior Art> Conventionally, as a tea making machine of this type, for example, a rough rolling machine is arranged to be connected to a container and a drive shaft inside the container,
Stirring hands and kneading hands (spatula) rotated by a driving source
It is composed of working hands such as

In such a coarse rolling machine, tea leaves are stored in the container, and the tea leaves are heated by hot air supplied from a furnace while the drive shaft is rotated by a drive source, so that the tea leaves are stirred by a stirring hand. The drying process is performed while stirring uniformly, and twisting is applied between the circular arc-shaped inner wall surface of the container and the kneading hands.

<Problem to be solved by the invention> By the way, in such a conventional rough kneading machine, since the kneading hands are made of metal such as an iron plate, slippage may occur between the kneading hands and the inner wall surface of the container. Since the frictional force necessary for the rolling process is not applied, there is a drawback that the tea leaves are not formed into needles smoothly.

For this reason, as shown in Japanese Patent Publication No. 49-22719, etc., by providing a large number of uneven parts on the surface of the kneading hands, a sufficient frictional force acts between the inner bottom surface of the container and the kneading hands. Conventionally, a method is known in which tea leaves are smoothly shaped into needles in this manner.

However, this conventional configuration has the following problems.

In other words, as the tea stains adhere to the concave portions provided on the surface of the kneading hands, harden, and become laminated, the concave portions are eventually blocked and the original effect of the concave and convex portions is completely lost. It was something to put away.

Therefore, it is necessary to periodically peel off and remove the hardened tea stains that have adhered to the recessed parts, and during this work, the operation of the equipment is interrupted, which takes a long time to start the furnace for restarting. It cost.

Processing the picked tea leaves as quickly as possible will greatly affect the flavor and finish of the product, so removing such tea astringency will reduce the operating rate of the equipment and will disrupt the tea manufacturing process. This also disrupted work and made it difficult to continuously produce products of uniform quality.

In addition, the uneven parts provided on the kneading hands have their shape, depth, direction, etc. changed in order to change the pressing force on the tea leaves, etc., depending on the type, flexibility, and hardness of the tea leaves.
It is preferable to vary the quantity; if these quantities are not appropriate, damage to the tea leaves may occur.

Therefore, it is necessary to change the kneading hands every time the type of tea leaves changes, but such changing of the kneading hands is similar to the above-mentioned process for removing tea astringency, etc.
This results in a decrease in the operating rate of the equipment, making it difficult to manufacture products with uniform quality.

Furthermore, the kneading hands are conventionally made of metal such as iron, but it is preferable to change the hardness etc. depending on the type of tea leaves, etc. However, since the kneading hands are made of metal, there is a limit to the adjustment range of the hardness etc. However, it is difficult to achieve a flexible touch and appropriate pressing force by hand, and it may also cause damage to the tea leaves.

In view of the above-mentioned conventional circumstances, the present invention was developed by applying sufficient frictional force between the arc-shaped inner wall surface of the container and the kneading hands to smoothly shape the tea leaves into needles, while also reducing the tea astringency in the kneading hands. In a tea making machine, the shape and degree of flexibility can be changed as appropriate in order to prevent the adhesion and hardening of tea leaves, etc., and to change the pressure force against the tea leaves depending on the type, flexibility, and hardness of the tea leaves. The purpose is to provide a kneading cover.

<Means for solving the problem> For this reason, the kneading hand cover in the tea making machine of the present invention is designed so that the kneading spatula has a gentle play space so that it can swing relative to the metal kneading spatula. To provide a hand kneading cover for a tea making utensil, which is formed into a flexible bag-like body or cylindrical body of a size that can be accommodated, and has a plurality of uneven parts formed on the outer surface of the rubbing side.

<Function> In this configuration, tea leaves are stored in the container, the drive shaft is rotated by the drive source, and the kneading hands are rotated, so that the tea leaves are moved between the arcuate inner wall surface of the container and the bag-shaped body (cylindrical body). ) and the outside rubbing surface is rubbed with a rubbing spatula.

In this case, since the sliding surface of the bag is provided with uneven parts, sufficient frictional force acts on the tea leaves sandwiched between the bag and the arcuate inner wall surface of the container, and the tea leaves are smoothly formed into needles. It will be done.

In addition, the inner diameter size of the bag-like (cylindrical) body cover is
The kneading spatula is relatively large in size compared to the outer size of the kneading spatula to be stored, and the kneading spatula is accommodated in the cover in a loose manner. Therefore, when the tea leaves are rubbed, the uneven parts of the rubbing surface of the bag swing and twist irregularly and come into contact with the arc-shaped inner wall surface of the container or come into pressure contact with the tea leaves. Due to the frictional force, the tea stains etc. adhering to the concave parts are rubbed off,
There is no accumulation. As a result, the original function of the uneven portion can be maintained.

Furthermore, it is possible to quickly and freely exchange various bags with different shapes, degrees of flexibility, etc., depending on the type, flexibility, and hardness of the tea leaves, and the pressure applied to the tea leaves can be arbitrarily and easily changed. This makes it possible to perform kneading similar to that achieved by hand, and to prevent damage to the tea leaves.

<Example> Next, an example of the present invention will be described based on the drawings.

FIG. 1 shows a rough rolling machine as an embodiment of the tea making machine of the present invention.

That is, in the figure, 2 is the body as a container for storing tea leaves, and has a halved cylindrical shape.
Both edges of the machine frame 1 are supported between the side frames 1A, 1A. Reference numeral 3 denotes a drive shaft rotatably attached to the machine frame 1, and to the drive shaft 3, working hands such as a kneading hand spatula 5 and a stirring hand 7 as working hands are attached via arm rods 4. . A plurality of these kneading spatulas 5 and stirring hands 7 are provided alternately at intervals on the drive shaft 3, and are rotated clockwise in FIG. 1 by the drive shaft 3. Further, a synthetic resin layer 8 having a corrugated surface is stretched and fixed on the inner wall surface of the bottom portion of the body portion 2 having an arcuate cross section.

Reference numeral 10 denotes a lid portion that covers between the side frames 1A and 1A above the body portion 2.

The kneading spatula 5 is housed and covered in a bag-like body 11 which can be freely attached and detached. In this case, the bag-shaped body 11 has a relatively loose accommodation space to house and cover the kneading spatula 5, and a play space 11a is formed inside (see FIG. 2).

The bag-shaped body 11 is made of a cloth or sheet made of a flexible and highly wear-resistant material such as carbon fiber cloth or plastic sheet material, and the sliding surface facing the synthetic resin layer 8 of the body 2 has a Many uneven parts 1
2 are integrally molded.

As shown in FIG. 3, this uneven portion 12 is formed by arranging elongated protrusions 15 at predetermined intervals and extending in the width direction of the rubbing surface of the rubbing spatula 5, that is, in a direction substantially perpendicular to the rubbing direction. . Alternatively, as shown in FIG. 4, a large number of columnar or spherical small protrusions 15 are formed in a random arrangement on the rubbing surface of the rubbing spatula 5.

Note that, instead of integrally molding the uneven portions 12 on the bag-like body 11, a separate strip-shaped sheet on which the uneven portions are formed may be adhered and fixed to the bag-like body 11.

The bag-shaped body 11 is fastened and fixed to the proximal end of the kneading spatula 5 by a binding device 14 such as a band at its opening.

The above hand kneading spatula 5 and bag-like body 11 constitute the hand kneading cover 13 of the present invention.

In this configuration, when tea leaves are stored in the body 2 and the drive shaft 3 is rotated by a drive source (not shown) while heating the tea leaves with hot air supplied from a furnace (not shown), the tea leaves are moved to the stirring hand 7. The synthetic resin layer 8 of the body 2 and the kneading cover 13 are uniformly stirred by the
Twisting is applied between the sliding surface 12 and the sliding surface 12.

According to this configuration, since the rubbing surface of the bag-shaped body 11 that covers the kneading spatula 5 is provided with the uneven parts 12, the tea leaves sandwiched between the synthetic resin layer 8 of the body part 2 and Frictional force acts and the tea leaves are kneaded without slipping, so the tea leaves are smoothly shaped into needles.

Since the kneading spatula 5 inside the bag-like body 11 is inserted and stored with a gentle play, the uneven portions 12 on the surface of the bag-like body 11 swing irregularly when the tea leaves are rubbed, and the synthetic resin Contact with layer 8 and friction with tea leaves occur in random directions. Due to the frictional force at this time, the tea stains and the like adhering to the recessed portions are scraped off and do not accumulate. As a result, the uneven portion 1
2. The original effect can be maintained, and there is no need to periodically remove hardened tea stains etc. that adhere to the kneading spatula 5 as in the past, preventing a decrease in the operating rate of the device, and ensuring uniform It becomes possible to continuously manufacture high-quality products.

Moreover, by quickly selecting and exchanging the shape, flexibility, etc. according to the type, flexibility, and hardness of the tea leaves, it is possible to change the pressure force applied to the tea leaves, which can prevent damage to the tea leaves and prevent twisting. It can prevent a lack of heat.

Therefore, each time the type of tea leaves changes, it is necessary to knead and spatula 5
There is no need for the complicated work of removing and replacing the arm rod 4, and it is possible to manufacture products with uniform quality without reducing the operating rate of the device.

In this embodiment, the tip of the kneading cover is closed to form a bag-like body, but it may be formed into a cylindrical body without being closed. Although we have described an example in which the present invention is applied to a rough rolling machine, it goes without saying that it can be similarly applied to a medium rolling machine.

<Effects of the invention> As explained above, the kneading device in the tea making machine of the present invention has many uneven parts on the outer surface,
Since the cover is a bag-like or cylindrical body that gently stores and covers the kneading spatula with play space, sufficient frictional force is applied to the tea leaves between the container's arcuate inner wall surface and the tea leaves Needle forming is carried out smoothly.
Moreover, since the kneading spatula is stored with play space within the cover and does not come into close contact with the cover, the uneven portions on the cover surface swing irregularly when kneading the tea leaves. The frictional force at this time scrapes off the tea stains and the like adhering to the recessed portions, preventing them from accumulating. As a result, the original function and effect of the uneven portion can be maintained.

Furthermore, depending on the type of tea leaves, softness and hardness,
It is also possible to quickly and freely exchange various bags with different shapes, degrees of flexibility, etc., and it is possible to arbitrarily and easily change the pressure applied to the tea leaves, etc., to achieve a finish similar to that achieved by manually rolling the tea leaves. Furthermore, it is possible to prevent tea leaves from being damaged, and also to prevent a decrease in the operating rate of the equipment, making it possible to continuously manufacture products with uniform quality.
