Display in 3). This communication is bidirectional, and the contents set by the control panels 11A to 18 are sent to the computer 22, and the contents changed by the computer 22 are transferred to the control panels 11.
It can be transferred to A-18 and changed (communication may be one-way from the control means to the management means, since there is no obstacle for carrying out the present invention, one-way communication is possible). This computer 2
2 and the display 23 are often provided in a corner room of a tea factory.

FIG. 2 shows the display means in the tea production FA system of the tea production factory in which the steamers 1A to 7B and the conveying device 8 are arranged, which is similar to the arrangement of the tea production factory 26. In the tea factory, there are other processes such as a fresh leaf chamber where a fresh tea leaf management device for storing fresh tea leaves and a dryer and subsequent steps such as selection, mixing, and bagging are performed.
Only the medium-heated tea production process of Nakabushi will be explained. The arrangement of this tea making machine varies depending on the tea making factory, and varies depending on the space of the tea making factory, the size of the tea making machine, the number of tea making machines, etc.
Not limited to this.

In the steamers 1A and 1B, steam is supplied from the boiler 27, and the fresh tea leaves supplied from the fresh tea leaf feeder 28 in a fixed amount are steam-heat treated. After that, the surface water is removed by the steam treatment machine 29, and the leaf cutter 2, the first rough kneader 3 and the second rough kneader 4 are used.
Rubbing is performed with A and 4B. The steamers 1A, 1B and the leaf beater 2 are continuous type, but the tea leaves for one cup of tea making machine are weighed by the weighing machine 10, and the batch machine after the first rough kneading machine 3 is a batch type. This tea making machine 1
The cup portion is called a roaster (robe) rather than the old tea making tools. next,
The kneading machines 5A and 5B knead the internal water content of the tea leaves, and the back middle kneading machine 6 and the middle kneading machines 7A and 7B perform the kneading and drying treatment again. afterwards,
The shaping process is performed by a refiner (not shown), but this is omitted in this embodiment.

Among these, the raw leaf feeder 28, steamer 1A, 1
B, the steam-leaf processing machine 29, the leaf-beating machine 2, the first roughing machine 3, the second roughing machine 4A, the kneading machine 5B, the middle kneading machine 7B, and a part of the transporting devices 8 and 25 are painted, which means that the tea leaves are It indicates that it is inside the tea making machine, and is green on the color display screen. Other unpainted second roughing machine 4

A, the kneading machine 5B is in use, so next, the second rough kneading machine 4B,
It seems natural to put it in the kneading machine 5A, but when both tea making machines to be distributed are not used or both are used conversely, it is difficult to know which one to put and the arrow is displayed like this. It is obvious at a glance. The arrow of the middle kneading machine 7B is painted out, which means that the middle kneading machine 7B is being charged.

Information 31 of tea leaves processed in each tea making machine
~ 34 are shown above the drawings of each tea making machine 1A-7B. Here, the roaster number (first cup, second cup, ...) And the variety of tea leaves are displayed, but information on other tea leaves may be displayed.
To set the tea leaf information 31 to 34, select the tea making condition change 35 in the input tea leaf setting 30 at the upper left, and on the tea making condition confirmation / change screen (not shown), select date, time, tea season, and weather. (Temperature, humidity), person in charge of tea making, producer, plucking method, variety, steaminess (tea making conditions), remarks, etc. are input. With this setting, it is possible to manage the tea leaf information for each roasting furnace. In addition, the items set on the confirmation / change screen of the tea-making conditions are not limited to this.

Reference numerals 41A to 47B in FIG. 2 indicate the operating conditions of each tea making machine. Normally, as shown in the operation status table 41B of the steamer 1B, the operation status table 44B of the second rough kneader, the operation status table 45B of the kneading machine 5B, the operation status table 46 of the rear center kneading machine 6 and the operation status table 47A of the middle kneading machine A. If only the set value and the current value are displayed and the cursor is moved to the operation status table you want to see, the operation status table 41A of the steamer 1A, the operation status table 42 of the leaf cutter 2 and the first rough kneading machine 3 are displayed. Operation status table 43, operation status table 44A of second rough kneader 4A, operation status table 45 of kneading machine 5A
A, items are displayed as in the operation status table 47B of the central kneading machine 7B. In addition to moving the cursor to the operation status table, when selected, the setting of the corresponding tea making machine is displayed in detail. That is FIG. 4, which is the detailed setting of the second rough kneader.

If the user wants to change the setting value, the setting value 58 can be changed by selecting the setting change 58 and adjusting the value with the arrow 56 to the right of the value. As it is, only the numerical value is changed on this screen. Therefore, when the transfer 59 is selected, the information is transferred to the second rough kneading machine control panel 14 and the setting value can be changed. At the same time, the screen returns to the monitor display. Further, after selecting the setting change 58, the monitor 57 can be selected to return to the monitor screen. To close this screen, press Close 60 or the X mark on the upper right.
When the history display 54 of the trouble content on the upper left is selected, the display shown in FIG. 5 is displayed.

In FIG. 5, the history of the trouble content in the second rough massage is displayed. If you select another tea making machine by the display machine name, only the history of the trouble content related to the selected tea making machine is displayed. If you select the whole, the trouble occurrence date of all the tea making machines connected, as shown in Fig. 6, Occurrence time, machine name,
The contents are displayed. The content of the trouble is a machine malfunction,
Not only the malfunction, human error, and operation error but also the quality defect during the tea making process can be displayed, which is useful for improving and stabilizing the product quality.

In FIG. 7, a small image is always displayed below the screen. When trouble occurs, keep displaying until it is resolved. Also, cautions that are not troubles are displayed in the same manner. Regarding this caution, when it occurs, it is preferable to display it as shown in FIG. 3 or to fill the display of the tea making machine of FIG. 2 with a specific color such as yellow.

Next, the flow when a trouble occurs will be described with reference to FIG. When a trouble occurs in the tea making machine and each control means detects it, code data corresponding to the trouble content is transmitted to the tea making FA system through an electronic signal.
The tea manufacturing FA system extracts the trouble content and the rank corresponding to the code data from the database and displays them according to the rank. At this time, the character color or the display frame is displayed in different colors according to the rank. Further, the tea manufacturing FA system records and registers the date and time of occurrence, the tea making machine, and the content of the detected trouble in the trouble history database as needed. When the trouble is solved, the corresponding trouble content is removed from the display, and the date and time of the solution, the tea making machine, and the content are registered in the trouble history database.

Next, FIG. 9 will be described. A database is prepared in advance, which is associated with the causes that can be inferred from troubles, the number of troubles that occur about special notes, and the frequency of occurrences within a certain period. When an actual trouble occurs, referring to the trouble history database, the number and frequency of occurrences are analyzed to search whether the corresponding inference result is registered, and if there is, display the contents. For example, if three or more misfires continue, the cause of fuel shortage will be inferred and displayed, and if there are two or more raw leaves shortage, the cause of dead leaves in the tea fresh leaf container will be inferred and displayed. If there is more than one possible cause, then display them. At that time, it is preferable to display the items with the highest possibility.
