Description

[Detailed explanation of the invention] [Technical field of the invention] This invention is used in small and medium-sized tea factories to aerate fresh tea leaves with cold air, store them, and automatically direct the fresh tea leaves to a steamer during processing. The present invention relates to a fresh tea leaf management device suitable for supplying tea leaves little by little.

[Technical background of the invention and its problems]

Utility Application No. 57-68844 (Utility Application No. 58-182646) as a fresh tea leaf management device for small and medium-sized tea factories.
There is an idea. By forming the ventilation member on the bottom with an air permeable conveyor 5, the green tea leaves are automatically carried out when they are supplied, and the drive body can be freely separated, so that one drive body can be used as a large number of green tea leaf management devices. It is designed so that it can be used in common with the main unit.

However, when supplying fresh tea leaves, the front wall on the supply end side is simply opened and the leaves are transported as is.
The green tea leaves stacked to a depth of about m are intermittently collapsed and fed, making it impossible to reliably and quantitatively feed the green tea leaves little by little to the steamer. Therefore, in reality, a wide conveyor is required to carry out a relatively large amount of green tea leaves that intermittently crumble without spilling elsewhere, and furthermore, a wide conveyor is required to carry out the relatively large amount of green tea leaves that intermittently crumble without spilling. An intermediate conveyor is also required to collect the fresh leaves and transport them to the steamer, so even if cost reduction is attempted by standardizing the drive unit, the cost is extremely high.

In addition, the drive body connects a unit consisting of a motor and a speed reducer to the drive shaft via a clutch, so its mechanism is complex, heavy, difficult for operators to handle, and expensive. be.

[Purpose of invention]

This idea was created in view of the above problems, and by installing a removable and common tea leaf scraping device behind the open front wall of the tea leaf management device, the above-mentioned problem can be solved. The purpose is to provide a tea leaf management device that solves problems.

[Structure of the idea]

In order to achieve the above object, the green tea leaf management device according to this invention has a permeable conveyor installed in the longitudinal direction on a machine frame equipped with a plurality of running wheels, and a conveyor with air permeability is installed in the middle part of the conveyor. A plurality of storage tank bodies are provided with a ventilation casing, longitudinal side walls, a rear wall, and a front wall that can be opened and closed are erected above the conveyor, and a large gear is attached to the roller shaft of the conveyor of the main body. A small gear that can be freely engaged and disengaged is attached to the main body, and the drive body is formed to be separable from the main body, and a scraping device is attached to the front wall after the opening and is separable from the main body. It is.

[Example of idea]

Hereinafter, embodiments of this invention will be described based on the drawings. 1, 2, 3, and 4 show examples thereof.

The storage tank body A has four running wheels 1 attached to the bottom of a machine frame 2, a conveyor 3 of a net belt (breathable) running around the longitudinal direction of the machine frame 2, and is equipped with a ventilation housing 4, and on the conveyor 3 there are longitudinal side walls 5, a rear wall 6,
and a front wall 7 is erected. Note that the blower housing 4 is equipped with a blower 8 and a humidifier (not shown in the drawings). The front wall 7 is formed to be openable and closable, and when opened, is accommodated in the upper part of the storage tank body A, and the entire surface thereof is opened.

At one end of the drive shaft 9 on the front side of the conveyor 3,
A relatively large gear 10 is mounted, and a motor fixture 11 is mounted on the upper side wall 5 adjacent to the gear 10.
Slide base 1 that supports the slide up and down freely
Fix 2. The motor fixture 11 is a U-shaped frame, one end of which is slidably accommodated in the slide base 12, and the other end of which is fitted with the deceleration motor 1.
3 and inserted into the U-shaped frame.
A small gear 14 is attached to the shaft 3. With the slide base 12 and the deceleration motor 13, the storage tank body A
A drive body B is formed which can be freely separated from the drive body B.

The scraping device C includes a frame 15 that is slightly smaller than the front wall 7, rotatable shafts 16, 16 that are horizontally mounted above and below the frame 15, and the shafts 16, 16 are connected to each other via a sprocket 17. Two chains 18 arranged between them, a large number of claw members 19 fixed to the two chains 18 so as to intersect with each other in a perpendicular direction, and a small motor 20 that drives the shaft 16.
It is constructed from lightweight materials with no waste. The scraping device C is installed after the front wall 7 after opening, and hooks 21 fixed to both ends of the upper part of the frame 15 are hooked to pins (engaging members) 22 at the upper part of the storage tank body A. The other end of the connecting rod 23, which is pivoted to both ends of the lower part of the frame 15, is hooked to a pin 24 at the lower part of the storage tank main body A, so that the lower part is also firmly fixed.

Next, use of the embodiment will be described. First, the front wall 7 is closed. The harvested green tea leaves are evenly thrown in without being pushed in from the open top surface. After the supply is completed, the blower 8 is operated. The air is blown from the ventilation case 4 between the upper and lower net belts of the conveyor 3, and further aerated through the upper net belt to be supplied between the green tea leaves stacked on top of the net belt. It removes heat and leaves the tea leaf layer. In this way, the tea is stored until processing.

When providing tea for processing, the storage tank body A containing the green tea leaves is transported to the input port of a leaf feeder (underground type) or to the production conveyor 25 (conveyor to the leaf feeder), and the front side is inserted into the input port or Place it on fresh leaf conveyor 25. Next, the front wall 7 is opened as shown in FIG. 3, and the back of the front wall 7 is opened. Then, a scraping device C prepared nearby is attached to the back of the front wall 7. That is, since the scraping device C is made of lightweight members and weighs 15 to 20 kg, it is carried, hung by the hook 21 on the pin 22 of the storage tank main body A, and then the lower part of the scraping device C is suspended. The connecting rod 23 is fixed to the pin 24. Connecting rod 23 and pin 24
The connection point with the tea leaves is adjusted so that the gap d becomes wider when a larger amount of green tea leaves is to be supplied or when the apparent volume is large, such as for summer tea.

Furthermore, drive body B prepared nearby in advance
is attached to the storage tank main body A along the slide base 12. The small gear 14 easily meshes with the gear 10 on the storage tank main body A side due to the weight of the deceleration motor 13 and the like and is connected to each other. Small motor 20 and deceleration motor 1
3 is turned on at the same time by a control device (not shown in the drawing) that controls the amount of fresh tea leaves in a leaf feeder, etc.
It shall be controlled to be OFF.

Therefore, when feeding green tea leaves, the deceleration motor 13
is driven, the conveyor 3 of the net belt is rotated very slowly via the small gear 14 and the gear 10 (so that the amount of scraping by the scraping device C matches the amount of conveyance by the conveyor 3). Waru. In addition, the small motor 20 also operates and the chain 1
8 rotates, the claw member 19 attached to the chain 18 touches the layer of green tea leaves that is gradually conveyed by the conveyor 3, scraping it up from the bottom to the top, and scraping it off little by little. .

When the supply of green tea leaves to the storage tank body A is completed, turn off the power switch (not shown in the drawing), remove the drive body B and the scraping device C, and return them to their original positions. Since the drive body B only has the small gear 14 resting on the gear 10 due to its own weight, it can be easily removed by simply pulling it upward without using a clutch or the like. Further, the scraping device C can also be easily removed by simply removing the hook 21 and the connecting rod 23.

If it is necessary to supply fresh tea leaves again, the storage tank body A filled with the next fresh tea leaves is brought in and the fresh tea leaves are supplied in the same manner.

[Effect of idea]

As described above, according to the green tea leaf management device according to this invention, an air permeable conveyor is installed in the machine frame provided with a plurality of running wheels in the longitudinal direction,
A ventilation housing is attached to the middle part of the conveyor, and a plurality of storage tank bodies are formed by vertically erecting both longitudinal side walls, a rear wall, and a front wall that can be opened and closed, and a roller shaft of the conveyor of the main body. A small gear that can engage and disengage freely is attached to a large gear that is attached to the main body, a drive body that is formed to be separable from the main body, and a scraping device that is attached to the front wall that is open and that is separable from the main body. Since the drive body B meshes and connects the small gear 14 and the gear 10 by its own weight, it can be easily installed or removed without the need for expensive and complicated parts such as a clutch. Furthermore, when the conveyor 3 is overloaded, the drive body B
It floats up and the small gear 14 of the deceleration motor 13
is idling and the motor 13 is protected.
Furthermore, by increasing the diameter ratio of the small gear 14 and the gear 10, the reduction effect is significant and the reduction ratio of the reduction motor 13 can be kept small, so that the reduction motor 13 can be made lightweight and compact. Furthermore, since the driving torque applied to the deceleration motor 13 can be reduced, the method for supporting the motor 13 can be simple. Next, after opening the front wall 7, a scraping device C is installed to slowly break up the stack of green tea leaves that are being conveyed little by little and allow them to fall, so that the stack does not collapse intermittently and It is taken out little by little without spreading around, and transported to the steamer, making it extremely inexpensive as there is no need for a wide conveyor like in the past.
By linking a leaf feeder or the like with a control device that controls the amount of fresh tea leaves, it is possible to unattend the long-time work of removing fresh tea leaves from the storage tank body A.
