DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 4, the medium fire system to which the present embodiment is applied is a variety of twisting machines including a 120K leaf punch 1, a 120K roughing machine 2, a 120K twisting machine 3, a 120K centering machine 4, and a 120K centering machine 5. And the conveying means (vertical bucket conveyors 6 to 10, vibration conveyors 11 to 15, and distribution conveyors 17 to 19) that connect these and constitute a conveyance line, and tea leaves steamed in the steaming process A fixed amount is charged, and the tea leaves are subjected to a cocoon drying process in each cocoon dryer in a batch process.
[0017]
In addition, the steaming system 16 in the figure includes an input raw leaf flow meter 16a for measuring tea leaves to be input to the line, a steamer 16b for steaming tea leaves and a cooler for removing moisture on the surface of steamed tea leaves. The tea leaves that have passed through the cooler 16c are transported to the vertical bucket conveyor 6 in the medium fire system.
[0018]
The tea leaves conveyed by the vertical bucket conveyor 6 are put into the leaf cutter 1 and subjected to leaf processing. The leaf cutter 1 is used as an initial operation of the rough dredge process. A hammer is fixed to a main shaft penetrating the trunk, and hot air from a hot air furnace is applied to tea leaves while rotating the hammer. It is a hit processing. A vibrating conveyor 11 is arranged below the leaf cutter 1, and the tea leaves after the leaf punching process are conveyed to the vertical bucket conveyor 7 by the vibrating conveyor 11.
[0019]
The tea leaves conveyed by the vertical bucket conveyor 7 are alternately put into the roughing machine 2 provided by the sorting conveyor 17 and subjected to roughing processing. This roughing machine 2 is a machine that heats the wet tea leaves with the steaming machine 16b of the steaming system 16 and heats them with the hot air guided into the machine, softens the tissue of the steamed leaves by compression and friction, and at the same time evaporates the moisture. It is.
[0020]
Further, the rough grinder 2 is configured such that a leaf grind and a hand are fixed to a main shaft passing through the tearoom into which tea leaves are placed, and hot air can be supplied from the hot air furnace into the firewood chamber. A vibrating conveyor 12 is disposed below the two roughing machines 2, and the tea leaves after the roughing process are conveyed to the vertical bucket conveyor 8 by the vibrating conveyor 12.
[0021]
The tea leaves transported by the vertical bucket conveyor 8 are alternately put into the twisting machine 3 provided in parallel by the sorting conveyor 18 and subjected to a twisting process. This twisting machine 3 is intended to facilitate the subsequent process operation by making up the moisture and making the moisture uniform with the roughing machine 2, and pressurizes the tea leaves put in from the receiving hopper 3a. It is configured to soften and break tissue. A vibrating conveyor 13 is disposed below the two twisting machines 3, and the tea leaves after the twisting process are conveyed to the vertical bucket conveyor 9 by the vibrating conveyor 13.
[0022]
The tea leaves conveyed by the vertical bucket conveyor 9 are put into the intermediate massaging machine 4 and subjected to a drying process. This medium grinder 4 removes the surface moisture of the tea leaves that have been swallowed by the twister 3 and performs sufficient swallowing with a wrinkle-type grabber (not shown), as well as solving small balls that are entangled with tea leaves. The shape is adjusted to facilitate shaping with a precision machine in the finishing process. A vibrating conveyor 14 is disposed below the intermediate massaging machine 4, and the tea leaves after the intermediate massaging are conveyed to the vertical bucket conveyor 10 by the vibrating conveyor 14.
[0023]
The tea leaves conveyed by the vertical bucket conveyor 10 are alternately put into the two intermediate machines 5 provided by the sorting conveyor 19 and subjected to a drying process. This crunching machine 3 is dried by hot air when the water inside the tea leaves oozes out by the twisting operation by the cramping machine 3, is twisted, and the water is evaporated to the average without drying outside. It is for adjusting the shape.
[0024]
In addition, the intermediate hoisting machine 5 is configured such that a split cylinder made of lining is lined on the inner surface of a short cylindrical body, and a hand is fixed to a shaft passing through the body, and the rotational direction of the body and the hand is the same. However, by making the rotation speed of the rower 1.8 to 2 times the rotation speed of the trunk, the tea leaves are also cut off due to the difference. A vibrating conveyor 15 is disposed below the intermediate dredge machine 5, and the tea leaves that have undergone a series of medium-heat processes are conveyed by the vibrating conveyor 15 to a finishing system (not shown) as a subsequent process.
[0025]
Of the various rice dryers related to the medium-fired system, the 120K twisting machine 3 is replaced with 240K, which has a large tea leaf capacity that can be twisted, and the subsequent medium update machine 4 and the medium basketing machine 5 are also changed to 240K. To do. Since 120K and 240K have different capacities for twisting tea leaves, batch processing in this step becomes impossible. In this embodiment, in order to avoid this, FIG. 1 and FIG. 2 (in FIG. 4) As shown in (enlarged part A), a conveyor-type weighing pool 28 is disposed above the 240K twisting machine 3 as a conveyance amount adjusting means.
[0026]
The 240K twisting machine 3 has the same configuration as the conventional one. More specifically, as shown in the schematic diagram of FIG. 2, a thick board 23 having a substantially circular recess at the center, A bowl 25 that can rotate while being eccentric on the concave portion of the board 23; a bowl arm 26 that extends outward from the side surface of the bowl 25; a crank 24 that connects the bowl arm 26 to the base frame 20; It is mainly composed of a base frame 20 that supports the crank 24 and the grid 23 and a hopper 22 for introducing tea leaves into the bowl 25. The pot 25 is applied with a moderate downward load by a weight (not shown).
[0027]
A frame 21 is disposed around the twister 3, and a conveyor-type measuring pool 28 is fixed to the upper surface of the frame 21. The conveyor-type measuring pool 28 is disposed between the roughing machine 2 (one paddy dryer) and the twisting machine 3 (other paddy dryer) in the previous process via the vibrating conveyor 12 and the vertical bucket conveyor 8. A conveyor belt 28c suspended between a pair of pulleys 28b, which temporarily holds the tea leaves unloaded from the roughing machine 2 and can carry the held tea leaves into the twister 3 at a predetermined timing; A bar-type load cell 28a for measuring the weight of the tea leaves on the conveyor belt 28c.
[0028]
In addition, the base end b of the conveyor-type weighing pool 28 is located below the charging port 8a of the vertical bucket conveyor 8, and the tip a is positioned above the receiving hopper 22 of the twister 3 via the charging chute 27. The tea leaves discharged from the charging port 8a to the base end b side of the conveyor belt 28c are dropped into the charging chute 27 from the tip a side and can be introduced into the receiving hopper 22. The tea leaves introduced from the receiving hopper 22 are accommodated in the bowl 25 and subjected to a sufficient twisting process by the bowl 25 that rotates eccentrically with the crank 24 while being pressurized with a weight by a driving source (not shown).
[0029]
According to such a conveyor-type weighing pool 28, the tea leaves sent from the roughing machine 2 in the previous process are temporarily held on the conveyor belt 28c, and the measured value is the set input amount (in this embodiment, two batches of the roughing machine). Since it is dropped from the tip side when it reaches the point and put into the receiving hopper 22, even if the processing capacity of the roughing machine 2 and the twisting machine 3 is different, batch processing can be continued and the receiving hopper The tea leaves can be surely dropped little by little with respect to 22. Further, since the tea leaves are transported by the transport belt 28c, it can be used as a part of the transport means from the roughing machine 2 (pre-process) to the twisting machine 3 (post-process), and a separate pool means is provided. Compared to the case, the installation space can be effectively used.
[0030]
Next, another embodiment according to the present invention will be described.
As in the previous embodiment, among the various rice dryers related to the medium-fire system shown in FIG. It is assumed that dredging machine 5 also changes the line to 240K. Since 120K and 240K have different capacities for twisting tea leaves, batch processing in this step becomes impossible. In this embodiment, in order to avoid this, in FIG. 3 (B portion in FIG. 4). As shown in (enlargement), a drive control means 29 as a conveyance amount adjusting means is connected to the vibrating conveyor 12 via a wiring 30.
[0031]
As shown in the figure, the drive control means 29 controls the drive timing of the vibrating conveyor 12 for conveying the tea leaves taken out from the two roughing machines 2, and from both of the two roughing machines 2. After the tea leaves are taken out, a signal is sent to the drive source of the vibration conveyor 12 via the wiring 30 to drive the vibration conveyor 12. The drive control means 29 may be provided in a control panel for controlling the roughing machine 2 or may be provided separately.
[0032]
According to the above-described embodiment, even when the tea leaves are taken out of the respective coarse brewing machines 2 provided at the same time, the tea leaves taken out first are temporarily held on the vibration conveyor 12 so that the tea leaves to be conveyed to the twisting machine 3 are always kept. Since constant control can be performed, batch processing can be continuously performed even if the dryers with different processing capacities (in the present embodiment, the twisting machine 3) are arranged in the line. For example, when three or more roughing machines 2 are arranged, the timing of the tea leaves to be taken out may be greatly shifted. However, every time the tea leaves for two of the roughing machines 2 are collected on the vibration conveyor by the drive control means 29, the vibrations are vibrated. It can be controlled to drive the conveyor 12 and is effective (in the case of this embodiment, the capacity of the twisting machine 3 is two batches of the roughing machine 2).
[0033]
As mentioned above, although this embodiment was described, this invention is not limited to this, Even if the pre-process and the post-process are adjacent to each other and the processing capacities of the dryers arranged in these are different from each other. For example, the present invention can be applied to a drying machine different from the machine shown in the embodiment. For example, even in the case of a line update in which the medium dredge machine 5 in FIG.
[0034]
Moreover, in the line of this embodiment, although the vibration conveyor and the vertical bucket conveyor are mentioned as a conveyance means, it may replace with them and may be another general-purpose conveyance means. For example, a belt conveyor or the like may be used instead of the vibration conveyor controlled by the drive control means 29. In this case, the drive timing of the conveyor belt is controlled. In addition, the line which comprises a medium-fired system may consist of another thing drought machine, for example, arrange | position the separate large-sized roughing machine called a wide roughing machine between the leaf cutter 1 and the roughing machine 2. May be. That is, the present invention can be applied to other various medium-fire line configurations.
[0035]
【The invention's effect】
According to the first aspect of the present invention, the user can expand the range of selection of the dryer at the time of line update, and for example, a tea factory that facilitates updating a machine that has been used in parallel with a single large machine. The space inside can be used effectively.
[0036]
According to the invention of claim 2, when the other dryers have different capacities due to the line update, the amount of tea leaves conveyed from one of the dryers is adjusted by the conveyor-type measuring pool while the other Since it is transported to the bottle dryer, it can be used as a part of the transport means from one bottle dryer to another bottle dryer, and the tea leaves can be carried into other bottle dryers little by little.
[0037]
According to the invention of claim 3, since the tip of the conveyor-type measuring pool is located above the receiving hopper of the twisting machine, the tea leaf charging port (receiving hopper) is smaller than other twisting machines. On the other hand, tea leaves can be easily introduced.
[0038]
According to the fourth aspect of the present invention, the amount of tea leaves transported from one rice dryer is adjusted by controlling the drive timing in the transporting means, so that separate adjusting means such as a pool can be dispensed with.
