Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a charging device for uniformly charging fresh leaves to a tea management device.

[Conventional technology]

In recent years, freshly picked tea leaves are stored in a tea fresh leaf management device that has both side walls standing on both sides of a breathable conveyor and blows air from below, and blows air from below to prevent deterioration due to heat generation of the fresh leaves. Every time, a raw leaf management device such as moving the conveyor to take out fresh leaves is becoming popular.
In this case, if there is unevenness in the placement of the fresh leaves, the air is blown at a part with low resistance (a part with low stacking or a part with low density).
Since it is easy to pass through the area, there is a risk that the fresh leaves will be denatured without sufficient air blowing in the areas with high resistance.

Japanese Patent Application No. 56-103296 was filed by the present applicant in the past, but the technique found in this application is to convey a narrow conveyor below the leading edge feeding type leaf feeder in order to solve the above problems. Is provided so as to be slidable from side to side, and by this means, it is intended to uniformly insert fresh leaves in the width direction of the tea fresh leaf management device.

[Problems to be solved by the invention]

This one exerts an excellent function when the supply of fresh leaves from the leaf feeder is always constant, but has the following drawbacks.

The variation in the amount of raw leaves supplied from the leaf feeder is
That is, it directly affects the placement of fresh leaves on the management device. In other words, if there is a part where the supply of fresh leaves is reduced or interrupted due to some reason in the middle, the stacking of fresh leaves will be low in that part, and if the nodules are supplied from the leaf feeder, it will be small. That is, the nodule remains on the management device, which causes uneven ventilation as described above, which causes alteration.

[Means for solving problems]

In order to solve the above problems, the present invention has the following structure below the delivery end of a transport machine that sets up both side walls on both sides of a breathable conveyor and feeds fresh leaves to a tea fresh leaf management device that blows air from below. A charging device with a different structure was attached. This throwing device includes a raw leaf pool having a width length substantially equal to that between the both side walls, a scraping tool formed by attaching a scraping claw to a rotary shaft provided at the bottom of the raw leaf pool over the entire width of the fresh leaf pool, and the transportation. It consists of a tea leaf sorter installed between the machine and the fresh leaf pool.

[Action]

The fresh leaves supplied from the transporter are stored in the fresh leaf pool while being sorted by the tea leaf sorter in the width direction of the fresh leaf pool. At the same time, the fresh leaves in the fresh leaf pool
It is scraped out by the scraping claw of the rotating scraping tool, but at this time, even if there is a variation in the flow rate of fresh leaves supplied from the transport machine due to some cause, it is temporarily stored in the fresh leaf pool and scraped out. It is absorbed while being scratched by the ingredient, and the flow rate of fresh leaves delivered from the fresh leaf pool becomes constant with only random variations. Further, at this time, even if the fresh leaves stored in the fresh leaf pool are not uniform in the width direction, they are evened out when being scraped out by the scraping tool and are uniformly sent out in the width direction.
Also, even if baby-nosed leaves are supplied from the transport machine,
It can be loosened to some extent when being scratched by the scraping tool. In other words, the fresh leaves delivered by the fresh leaf pool are evenly dropped in the width direction between both side walls of the fresh tea leaf management device, and the flow rate is always constant, so that the fresh leaf placement surface on the fresh tea leaf management device is flat. The internal density is also constant.

The scraping and equalizing tool 16 is also rotatably attached to the machine frame 12 by a bearing 20a, and the scraping and smoothing claws 23 in the shape of, for example, a round bar are alternately shifted 90 degrees on the shaft 20 extending in the width direction of the machine frame 12. It is formed so as to penetrate a large number.

For mounting the bearing 20a that holds the shaft 20 of the scraping and leveling tool 16, for example, by mounting the mounting height with bolts and nuts in a long hole provided in the machine frame 12, the flow rate of fresh leaves can be adjusted. Make it adjustable. This adjustment is preferably performed so that the flow rate of fresh leaves delivered from the fresh leaf pool 17 is substantially equal to or slightly larger than the flow rate of delivery of the transportation machine 8.

Then, the rotary shaft 18 of the scraping tool 15 and the scraping tool 16
The sprockets 24a and 24b are attached to one end of the shaft 20 of each of the sprocket 24c and the sprocket 24c attached to the output shaft 27 of the motor 26 attached to the machine frame 12 by the motor attaching stay 25, and connected by the chain 42. Therefore, when the motor 26 operates, the rotary shafts 18 and 20 rotate in the directions shown by the arrows in FIG.

In the present embodiment, a scraping tool 15 is provided on the upper part of the scraping tool 15.
16 is provided, one wall of the fresh leaf pool 17 is formed with these, and further, the delivery flow rate of the fresh leaves is adjusted by adjusting the position of the scraping tool 16 in the vertical direction, but the scraping tool 16 is omitted. The flow rate of fresh leaves may be adjusted by changing the number of rotations of the rotary shaft 18 of the scraping tool 15.

Further, a flat plate may be provided as an auxiliary to a portion other than the delivery path of the fresh leaves by the scraping tool 15 to enhance the airtightness of the fresh leaf pool 17.

Next, the tea leaf distributor 28 provided between the transport machine 8 and the fresh leaf pool 17 will be described.

This tea leaf allocating device 28 is preliminarily distributed in the width direction of the fresh leaf pool 17 to some extent in advance so that when the fresh leaves supplied from the transporter 8 into the fresh leaf pool 17 are scraped out by the scraping device, the fresh leaves are uniformly sent out in the width direction. Although various forms are adopted, it is desirable that at least the fresh leaves are distributed in three or more positions in the width direction.

In this embodiment, the following configuration is adopted.

A moving conveyor 29 reciprocates on a traveling rail 30 mounted on the machine frame 12 so as to cover the entire width of the fresh leaf pool 17 immediately above the fresh leaf pool 17.

Reference numeral 31 is a vehicle body of the moving conveyor 29, and an axle 32 is rotatably supported at the front and rear of the vehicle body 31, and four wheels 33 are attached to the axle 32.
Are mounted to hold the moving conveyor 29 on the traveling rail 30.

A drum shaft 34 is pivotally supported at both front and rear ends of the vehicle body 31, and a rubber belt 35 is stretched between the drum shafts 34 so as to surround the vehicle body 31.

A motor 36 is mounted on the vehicle body 31, a pulley 38a attached to an output shaft 37 of the motor 36 is connected to a pulley 38b attached to one end of the axle 32 by a V belt 39a, and the pulley 38b is A pulley 38c attached to one end of the drum shaft 34 and a V belt 39b are connected to each other. Therefore, the output shaft 37 of the motor 36, the axle 32, and the drum shaft 34 rotate in the same direction. In other words, the tea leaves on the rubber belt 35 are
It is delivered to the moving direction side of the moving conveyor 29.

40 is a limit switch mounted on the machine frame 2
When it comes into contact with the sensed part 41 attached to 31, a command for reversing the rotation of the motor 36 is sent. Therefore, the mobile conveyor 29
Reciprocates on the traveling rail 30 during operation.

Next, the operation of each part will be described along with the method of using the device.

There are several methods for introducing the fresh leaves into the whole-area input type fresh-leaf management apparatus as in the embodiment, but here, the transport device 8 is slowly and repeatedly moved back and forth within its moving range. First, fresh leaves are always sent out from the front side of the transporting machine 8 (outgoing end side of the conveyor 2), firstly the fresh leaves are put into the front half of the storage tank, and when the feeding is finished properly, then the fresh leaves are sent to the transporting machine 8. The method of sending out from the opposite direction and putting it in the rear half of the storage tank will be taken up.

The energization of the motors 26 and 36 is interlocked with the energization of the transport machine 8. However, only the loading device 11 in the transport direction of the transport machine 8 is operated, and the stop is carried out for a while after the transport machine 8 is stopped. Give time.

Therefore, if the transport plane 8 is operated and the transport surface of the endless transport belt 10 is moved forward while slowly reciprocating on the rail 9, the scraping tool 15 and the scraping tool 16 start rotating at the same time, On the other hand, the moving conveyor 29 reciprocates on the traveling rail 30, and the conveying surface of the rubber belt 35 moves in the same direction as the moving direction of the moving conveyor 29.

Then, when the fresh leaves are sent from the fresh leaf supply conveyor 7 onto the transport machine 8, the fresh leaves are transferred one after another on the moving conveyor 29 of the loading device 11 attached to the front side of the transport machine 8 as the endless transport zone 10 moves. Then, as the moving conveyor 29 moves, it is thrown into the fresh leaf pool 17 below it across the width thereof.

Then, the fresh leaves are scraped up by the drum type diffusing tools 21 and 22, and while being leveled by the scraping leveling tool 16, from between the drum type diffusing tools 21 and 22 and the scraping leveling tool 16, uniformly over the entire width thereof. Sent out.

That is, the fresh leaves supplied from the transportation device 8 are used as the fresh leaf management device 1
Before being put in, the storage tank 2 is preliminarily spread in the width direction and then uniformly put in the width direction, so that the apparent density of the fresh leaves to be delivered becomes low.

This also means that the effect of loosening the fresh leaves can be obtained, and the variation in the delivery amount due to the nodule-like fresh leaves is reduced.

In addition, since the leaves are loosened and dropped, the cooling effect by exposing the fresh leaves to the outside air during that time is enhanced.

Actually, there is a variation in the flow rate of fresh leaves delivered from this device, but this variation is due to chance, and the variation that is caused by the flow rate delivered from the transport machine 8 is in the fresh leaf pool 17. Since it is absorbed by, the range of variation is small and it does not pose any problem when viewed comprehensively.

Moreover, this apparatus moves only in the longitudinal direction of the fresh leaf management apparatus 1, and there is no variation in the width direction due to the movement of the apparatus.

In this way, while uniformly dropping the fresh leaves from the fresh leaf pool 17 in the width direction of the management device 1, the transport machine 8 itself is reciprocated in the longitudinal direction of the management device 1 so that a desired amount of fresh leaves is provided in the front half of the conveyor 2. After being placed, the transfer direction of the endless transportation zone 10 of the transportation machine 8 is reversed next, and similarly, fresh leaves may be placed on the rear half of the conveyor 2.

Then, the air blower 4 appropriately ventilates the air, and the conveyor 2 is moved whenever necessary to scrape off the fresh leaves on the conveyor 2 and the device 5 drops them little by little onto the vibrating conveyor 6 and supplies them to the next step. To do.

The device of the present invention can be applied not only to the whole-area feeding type as in the embodiment but also to a single-end feeding type fresh tea leaf management apparatus as shown in Japanese Patent Application No. 56-103296.

〔effect〕

As described above, according to the present invention, when the fresh leaves are placed on the tea fresh leaf management device, the variation caused by the flow rate of the fresh leaves sent from the transport machine is temporarily removed from the fresh leaves in the fresh leaf pool. By storing it, it is possible to change it to an accidental variation, and the fresh leaves sent from the fresh leaf pool are
By the tea leaf sorter and the scraping tool, the tea leaves are thrown while being uniformly loosened in the width direction of the conveyor of the fresh tea leaf management device.Therefore, unevenness is formed on the placement surface of the fresh leaves placed in the fresh tea leaf management device. It is difficult to prevent deterioration of quality due to uneven ventilation.
