Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a tea scattering device for scattering tea leaves sent from a tea leaf dropping transporter onto a placing surface.

[Conventional technology]

In recent years, the use of fresh leaf management devices such as "conveyor type,""pittype," and "mobile container type" has become popular when storing fresh leaves. Normally, fresh leaves are dropped using a transporter for dropping fresh leaves.

However, if the fresh leaves are simply dropped from a transporter onto the placing surface, the placed fresh leaves tend to form clumps, causing uneven ventilation and degrading the quality of the tea leaves.

Therefore, a number of devices have been tried in the past for dispersing fresh leaves sent from transporters. The device described in Japanese Patent Application Laid-Open No. 59-102326 is one of them, and this device is equipped with an umbrella-shaped tea leaf dispersing blade that is rotatably placed in the middle of the fall of fresh leaves sent from a transporter. The fresh leaves are then placed while loosening them. In particular, FIGS. 5 to 9 show a device in which an umbrella-shaped dispersing blade is attached to a vertical rotating shaft.

[Problem that the invention seeks to solve]

However, in the above device, the dispersing blades descend as they move away from the center of rotation in the centrifugal direction, so the spreading width of fresh leaves is narrow, and if the placement surface is vast, the transport I had to move it back and forth many times, both horizontally and vertically.

In addition, fresh leaves that fall onto the dispersing blade immediately slide down the slope under the influence of centrifugal force and gravity, and the time that the fresh leaves are on the dispersing blade is short, so the distribution state of the placed fresh leaves is The airflow was not uniform around the rotation axis, leading to problems such as uneven ventilation.

The above conditions are briefly shown in Figures 1 and 2.
A is a transporter for dropping tea leaves, B is a rotating shaft, C is a dispersion blade, and D is a mounting surface.

[Means for solving the problems] In order to solve the above problems, the present invention has the following configuration.

That is, the tea scattering device for the tea leaf dropping transport device of the present invention is provided with a tea scattering tray that has a vertical axis of rotation and rotates at an appropriate speed during the drop of tea leaves from the transportation device, and the shape of this tea scattering tray is adjusted. , is formed to have a slope that rises as it moves away from the rotating shaft in the centrifugal direction, and a resistance portion is provided on this slope substantially in the centrifugal direction.

[Effect]

The operation of the tea scattering device in the tea leaf dropping transport device of the present invention will be described below.

The tea leaves sent by the tea leaf dropping transport machine fall onto a scattering tray that rotates at an appropriate speed, and the tea leaves rise as they move away from the rotation axis in the centrifugal direction. The tea leaves that have fallen onto the slope are rotated by the resistance part along with the tea bowl, are subjected to centrifugal force, and go up the slope, and are released and scattered around the tea bowl. Because of the momentum, it moves down the slope to near the rotation axis, and then, due to centrifugal force, it moves up the slope and is released and scattered around the tea tray.

At this time, it takes time for the tea leaves to be scattered after they fall onto the slope, so they are spread evenly around the rotating shaft.Also, the tea leaves are released upward along the slope, so they are not placed on the slope. The spread width of tea leaves is wider than before.

This state is briefly shown in Figures 3 and 4 as an example, where A' is a transporter for dropping tea leaves, B' is a rotating shaft,
C' is a tea dish, and D' is a mounting surface.

〔Example〕

Next, a case where the tea scattering device of the present invention is attached to a feeding device of a fresh leaf management conveyor of an area feeding type will be explained using an example shown in the drawings.

Reference numeral 1 denotes a tea scattering device of the present invention, which is attached to the left and right ends of a second transporter 2 so that fresh leaves introduced from the second transporter fall into a tea scattering tray 3, which will be described later.

The second transporter 2 has rails 6 provided along both side walls 5 of a conventionally known fresh leaf management conveyor 4.
It is capable of moving left and right on its own using wheels 7, and has a first transporter 8 orthogonal thereto above.

9 is the machine frame of the fresh leaf management conveyor,
Reference numeral 10 denotes an air-permeable conveyor constructed by connecting a large number of caterpillar plates 10'.
1, each section is ventilated.

Reference numeral 12 indicates a driving portion of the conveyor, 13 indicates a side wall, 14 indicates an end wall, and 15 indicates an end wall on the sending side.

16 is a scraping device, and 17 is a vibrating conveyor for feeding leaves to the next steaming process.

7 and 8, a mounting machine frame 20 is attached to the end of the second transport machine 2, and this mounting machine frame 20
A rotary shaft 21 is rotatably attached to the second transport device 2 by bearings 22a and 22b so as to be located at the center in the width direction of the transport zone 18 of the second transport device 2.

Further, the rotating shaft 21 is provided with a bevel gear 23, and this bevel gear 23 is a transmission shaft orthogonal to the rotating shaft 21 rotatably mounted on the mounting machine frame 20 by bearings 25a, 25b. The transmission shaft 26 meshes with a bevel gear 27 provided at one end of the transmission shaft 26.
A sprocket 28 is attached to the other end.

This sprocket 28 is connected by a chain 29 to a sprocket 31 attached to a driven shaft 30 of the second transport machine 2.
When activated, the rotation of the driven shaft 30 is transmitted to the rotation of the rotary shaft 21.

Next, the shape of the tea bowl 3, which is the main part of the present invention, will be explained.

In this embodiment, the tea dish 3 is constructed by, for example, six flat plates 32 successively attached to form a substantially hexagonal pyramidal slope 3.
3, and with the apex 35 of this hexagonal pyramid facing downward, attach the stopper 34 at the position of this apex 35,
This stopper 34 is formed by attaching the rotating shaft 21.

In this case, the joining sides 37 of the adjacent flat plates 32 become the resistance portions 36.

Further, in this embodiment, the width L of the tea dish 3 is approximately equal to the width of the transport zone 18, and the slope angle α is 35°.

There are two methods for placing fresh leaves on the fresh leaf management conveyor in the above embodiment using the first transporter 8 and the second transporter 2: an entire area loading method and a starting end loading method.
Since these methods are conventionally known, only the case where fresh leaves are charged using the starting end feeding method will be briefly explained.

First, move the second transporter 2 along the rail 6 so that the right end of the second transporter 2 faces near the starting end of the fresh leaf management conveyor 4, and then move the second transporter 2 along the rail 6 so that the upper surface of the transport belt 18 moves to the right. When the second transport device 2 is operated, the rotation of the driven shaft 30 is transferred to the transmission shaft 26 via the sprocket 31, the chain 29, and the sprocket 28.
The rotation shaft 21 is further rotated via the bevel gear 27 and the bevel gear 23.

Therefore, when the first transporter 8 is operated to supply fresh leaves onto the second transporter 2, the fresh leaves fall one after another from the right end of the transport belt 18 into the rotating tea leaf tray 3.

Then, the fresh leaf is attached to the joining edge 37 of the adjacent flat plates 32.
It rotates with the tea dish by the barrel resistance part 36, receives centrifugal force, ascends the slope 33, is released around the rotation axis, and a part of it is pushed down the slope 33 to the vicinity of the rotation axis 21 due to the force of falling. , then ascends the slope 33 due to centrifugal force, and is released around the rotation axis.

At this time, the height of the tea dish 3 from the conveyor 10,
Alternatively, if the above-mentioned slope inclination angle α etc. are formed so that the scattering width L of the fresh leaves is slightly larger than the width of the conveyor 10, the state of the fresh leaves placed on the conveyor is such that the vicinity of the side walls 5 are raised. Although it may seem stylish, if the fresh leaves placed on the conveyor 10 are ventilated from below, the ventilation will easily pass just inside the side wall.
It is more convenient to place it in this manner.

Then, when the stack reaches a certain height, the conveyor 10 is moved forward a little, and fresh leaves are similarly scattered and stacked.

In addition, in this embodiment, since the joint side 37 of the adjacent flat plates 32 is used as the resistance part 36, the tea leaves are not easily damaged and the quality is not deteriorated.

In addition, the tea scattering device of the tea leaf dropping transport device of the present invention can be used not only for transporting tea leaves to the fresh leaf management conveyor as in the above embodiment, but also for dropping tea leaves to a “pit type” fresh leaf management device. Of course, it can be carried out on a transport machine, but it can also be carried out on any type of transport machine for dropping tea leaves onto a surface on which tea leaves are placed, such as a tea leaf combination machine.

9a to 9d show other embodiments of the scattering tea dish. In FIG.
In FIGS. and d, the flat plates 32 are assembled into an octagonal pyramid shape, and the joint sides 37 thereof serve as the resistance portions 36, and a notch portion 39 is further provided.

Further, in FIG. b, a perfectly circular flat plate 32 is bent into a dogleg shape to form two slopes 33, and a resistance portion is formed on the slopes 33 by a thin plate 38.

〔effect〕

According to the tea scattering device for dropping and transporting tea leaves devised in the present application, the tea leaves that have fallen onto the tea scattering tray are widely and evenly scattered around the rotating shaft of the tea scattering tray, so that the tea leaves are placed without forming lumps. be done.

In addition, if the loading surface is large, it is necessary to drop the tea leaves while moving the tea leaf dropping transport machine vertically and horizontally, but at this time, since the scattering width is wide, the moving distance of the transport machine can be shortened and power consumption can be reduced. In addition, if the surface on which the tea leaves are placed, such as a fresh leaf management conveyor, is within the width of the tea leaf scattering device, there is no need to move the transporter.

Further, according to the present invention, it is possible to widely scatter tea leaves even in places where the height space from the placement surface is small.
