By doubling, the difference is applied to the tea leaves. A vibration conveyor 15 is provided below the middle massage machine 5, and the tea leaves having undergone a series of medium heat processes are conveyed by the vibration conveyor 15 to a finishing system (not shown) which is a subsequent process.

Among the various types of kneading and drying machines related to the medium fire system, the 120K kneading machine 3 is replaced with 240K, which has a large capacity of tea leaves capable of kneading, and the subsequent middle kneading machines 4 and 5 are also changed to 240K. Assume an update. 120
K and 240K have different capacities for kneading tea leaves, so that batch processing in this step becomes impossible. However, in order to avoid this, in this embodiment, FIG.
As shown in FIG. 2 and FIG.
A conveyor-type measuring pool 28 as a conveyance amount adjusting means is disposed above the K kneading machine 3.

The 240K kneading machine 3 has the same structure as that of the conventional kneading machine. However, in detail, as shown in the schematic diagram of FIG. 2, the kneading machine 23 made of a thick plate having a substantially circular concave portion in the center.
And a bowl 25 rotatable while being eccentric on the concave portion of the kneading machine 23
And a pot arm 26 extending outward from the side surface of the pot 25,

And a hopper 22 for introducing tea leaves therein. The bowl 25 is given a moderate downward load by a weight (not shown).

A frame 21 is provided around the kneading machine 3, and a conveyor type measuring pool 28 is fixed on the upper surface of the frame 21. The conveyor type measuring pool 28
Is disposed between the coarse kneading machine 2 (one kneading and drying machine) and the kneading machine 3 (other kneading and drying machine) in the preceding process via the vibration conveyor 12 and the vertical bucket conveyor 8. The tea leaves transported from the conveyor belt 28c are temporarily held, and the held tea leaves can be carried into the kneading machine 3 at a predetermined timing. A bar-type load cell 28a for measuring the weight of tea leaves.

The base b of the conveyor type measuring pool 28
Is located below the input port 8a of the vertical bucket conveyor 8, and the tip a is
The tea leaves discharged from the inlet 8a to the base end b of the conveyor belt 28c are positioned above the receiving hopper 22.
Of the receiving hopper 22
It is configured so that it can be introduced into. And
The tea leaves introduced from the receiving hopper 22 are housed in a pot 25 and subjected to a sufficient kneading process by the pot 25 eccentrically rotated by the crank 24 while being pressed by a weight by a drive source (not shown).

According to the conveyor type weighing pool 28, the tea leaves sent from the rough rubbing machine 2 in the previous process are temporarily held on the conveyor belt 28c, and the weighing value is set to the set amount (in the case of the present embodiment, the coarse rubbing machine 2). When it reaches the batch hopper, it is dropped from the front end side and put into the receiving hopper 22, so that even if the processing capacity of the rough kneader 2 and the kneading machine 3 is different, the batch processing can be performed continuously. Thus, the tea leaves can be surely dropped into the receiving hopper 22 little by little. In addition, since the tea leaves are transported by the transport belt 28c, the tea leaves can be used as a part of transport means from the coarse kneading machine 2 (pre-process) to the kneading machine 3 (post-process), and a separate pool means is provided. As compared with the case, the installation space can be effectively used.

Next, another embodiment according to the present invention will be described. As with the previous embodiment, the capacity of the tea leaves capable of kneading the 120K kneading machine 3 among the various kneading and drying machines according to the medium fire system shown in FIG.
It is assumed that the subsequent middle kneading machine 4 and the middle kneading machine 5 are also updated to 240K. 120K and 240K have different capacities for kneading tea leaves, so that batch processing in this step becomes impossible. However, in order to avoid this, in this embodiment, FIG. 3 (part B in FIG. 4) As shown in (enlargement), a drive control unit 29 as a conveyance amount adjusting unit is connected to the vibration conveyor 12 via a wiring 30.

As shown in FIG.
It controls the drive timing of the vibrating conveyor 12 for transporting the tea leaves taken out of the two rough massage machines 2,
After the tea leaves are taken out from both of the two rough massage machines 2, 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 coarse kneading machine 2, or may be provided separately.

According to the above-described embodiment, even if the timing of taking out the tea leaves of the respective coarse kneading machines 2 is different, the tea leaves taken out first are temporarily held on the vibrating conveyor 12 and conveyed to the kneading machine 3. Since the tea leaves can be controlled to be always constant, batch processing can be continuously performed even if kneading dryers having different processing capacities (in this embodiment, kneading machines 3) are arranged in the line. it can. In addition, for example, when three or more coarse kneading machines 2 are provided, there is a possibility that the timing of the tea leaves to be taken out may be largely shifted.
9 can be controlled to drive the vibrating conveyor 12 each time two tea leaves of the coarse kneading machine 2 accumulate on the vibrating conveyor, which is effective (in the case of this embodiment, the capacity of the kneading machine 3 is 2 Batch.)

Although the present embodiment has been described above, the present invention is not limited to this, and the pre-process and the post-process are adjacent to each other, and the processing capacities of the kneading dryers disposed therein are different from each other. In this case, the present invention can be applied to a kneading dryer different from the machine described in the embodiment. For example, even in the case of a line update in which the middle kneader 5 in FIG. 4 is changed to a large one (for example, 240K), if the present invention is applied,
Batch processing in the medium heat process can be performed continuously.

Further, in the line of the present embodiment, a vibration conveyor and a vertical bucket conveyor are mentioned as the conveying means, but other general-purpose conveying means may be used instead. For example, a belt conveyor or the like may be used instead of the vibration conveyor controlled by the drive control unit 29, and in this case, the drive timing of the transport belt is controlled. In addition, the line which comprises a medium-fire system may consist of other kneading-drying machines, for example, arrange | positioning a separate large-sized rough kneading machine which becomes a wide coarse kneading machine between the leaf driving machine 1 and the rough kneading machine 2. You may. That is, the present invention can be applied to other various medium-fire line configurations.

[0035]

According to the first aspect of the present invention, the range of selection of the drying machine by the user at the time of updating the line is expanded, and
For example, it is possible to easily replace a plurality of machines that have been used in parallel with one large machine, thereby effectively utilizing the space in the tea factory.

According to the second aspect of the present invention, when the capacity of another kneading dryer is changed by line renewal, the amount of tea leaves conveyed from one kneading dryer is adjusted by the conveyor type measuring pool. As it is transported to other kneading dryers, it can be used as a part of the transportation means from one kneading dryer to another kneading dryer, and the tea leaves are transported to other kneading dryers little by little. Can be.

According to the third aspect of the present invention, since the tip of the conveyer type measuring pool is located above the receiving hopper of the kneading machine, the tea leaf input port (receiving hopper) as compared with other kneading and drying machines.
However, tea leaves can be easily fed into a small kneading machine.

According to the fourth aspect of the present invention, since the amount of tea leaves conveyed from one kneader-dryer is adjusted by controlling the drive timing of the conveying means, it is not necessary to use a separate adjusting means such as a pool. it can.
