A brown rice sorting and weighing device E is arranged on the brown rice outlet side of the rice brown rice sorting section, and finished brown rice from which waste rice has been removed is packed in a predetermined weight bag. 43
Converter for connecting the facility appropriate location central control panel in which is installed in the keyboard 45 to the control unit 44, a color CRT 46, each drying device B _1, B ₂ ... arranged in the control panel 47, 47 ... it is 48, a power box 49 for receiving signals from a detection sensor and amplifying a signal to drive the equipment. A touch panel 50 is formed on the surface of the color CRT 46, and a pick signal (a signal generated based on pressing the designated position of the panel 50 by a finger) is input to the control unit 44 via the interface 51. The touch panel 50 has a known configuration, and is formed of a single glass sensor. A conductive film having a uniform resistivity is printed on both surfaces of the sensor, and input is performed by lightly touching (picking) the screen with a finger. Things.

The central control panel 43 has normal operation operation functions such as filling, drying, grain movement, discharge, hulling, stop, etc.
It has a function to monitor and display the status of each drying device, customer status, etc., and a data management function. In addition, the drying devices B ₁ and B ₂
... The setting of individual operating conditions, for example, the filling amount, the finish moisture value, etc., is performed by operating a setting switch provided on each control panel of the drying device.

FIG. 7 shows an example of the CRT 46 screen on which a pick operation can be performed. 1 to N
O. 4 of the drying apparatus b ₁ ~b _4, rice tank c, hulling machine d, Chokomi and discharge conveyor e, respectively layout graphical representation of f, the character display unit h of in its lower operating switches g and abnormal content Is provided. Each drying device b ₁ , b ₂
.. Are vertically divided into a cooling unit and a storage / drying unit, and are configured to be able to color-code the presence or absence of grain storage. For example, the display colors are black without grains, green before drying, magenta during drying, and white after drying. In addition, the condition of the contained grains depends on their moisture level,
This is a configuration in which a grain temperature, a drying temperature, and the like are numerically displayed and represented.

The grain drying devices B ₁ , B ₂ ... The individually provided control panels 47 are installed in the drying section 4 and the cooling tank 5 respectively.
Drying (or ventilation), moving, discharging and stopping switches 5
2, 53, 54, 55, 56, and 57, 58, 59,
60 and 61 are provided. On the upper part of each of these switches, monitor lamps 62, 62,... For notifying that the operation is currently being performed, and monitor lamps 63, 6 for notifying the permission or prohibition of the shift of the operating state and switching on and off.
3 are provided.

The control panel 47 has, in addition to the above switches, operation switches 64, 65, and 66 for setting drying conditions such as the type of grain, the set moisture, and the amount of stuffing. Reference numeral 67 denotes a single / double setting switch.
While the standard work is performed so that the cereal stuck in the drying unit 2 is returned from the drying unit 2 to the storage unit 1 through the elevator 15 and the opening a, the fresh cereal is also stored in the cooling tank 5 in the double setting. The switching valve 17 is of a second opening-open type, and the bottom valves 30 and 30 are configured to rotate.

The operation of the above example will be described. Grains harvested in the field, for example, paddy, are transported by trucks or the like, and thrown into the pit A. The user instructs the start of the filling from the color CRT 46 screen of the central control panel 43, and inputs the filling destination drying device, the name of the customer, and the type of grain. The loading device is selected by selecting one of the empty drying units of the grain drying device graphically displayed from the basic pattern screen and performing a pick operation (FIG. 8). This is performed by sequentially performing a pick operation from the sound kana character display. When these setting operations are completed, a confirmation display of "YES" or "NO" is displayed for the start of the insertion,
The operation is started by picking “YES”. The insertion start signal causes the power box 49 to output a start signal for a driving motor (not shown) for the insertion elevator 41, the insertion conveyor 39, and the like. The elevator 15 of the designated drying device (No. 1 in the example in the figure) is a converter 48.
It is started by a drive command from the control unit 47 output via the.

The cereal thus received in the pit A is lifted by the elevator 41 and supplied to the start end of the conveyer 39. When the filling is completed, the operation proceeds to the drying operation. At this time, the display is returned to the basic pattern screen, and when there is grain filling, the CRT 46 displayed based on the previous color display is displayed.
The drying device b to be dried is selected by a pick operation on the screen. Then, a setting state confirmation screen of the grain stuck on the drying device is displayed. In other words, when the conditions need to be changed, the control units 47 provided in the individual drying devices B ₁ , B _2, ... Do this in. When drying is permitted, a "dry" switch on the screen is picked to issue a drying execution command (FIG. 9).
In this case, since the staking operation cannot be executed, it disappears from the screen display, and only the executable operation state can be displayed.
Incorrect operation is prevented. When each condition is satisfied, the screen is switched to a screen prompting confirmation, and "YES" or "NO" is selected in the same manner as the insertion. The drying operation signal is input to the control unit of the drying apparatus through the converter 49, and outputs signals necessary for drying, such as a combustion signal of the burner 6, a start signal of each rotating unit, and the like.

During the repetition of the drying / circulating refining process, the finishing water value reaches a preset value, and the drying is completed. The grain in the storage section 1 of the grain drying apparatus thus finished can be selected as “moving” to be discharged to the cooling tank 5 or “discharge” to be directly discharged to the external discharge conveyor 34. That is, when the cooling tank on the storage unit used for the drying is empty, “Move” is picked from the basic pattern screen.
A signal is output to the control unit of the drying device, and a drive signal of a switching motor (not shown) for the switching valve 17 and a drive signal of a circulation system motor such as the elevator 15 are output. The grain dried and finished in the drying section is transferred to the upper cooling tank 5 where the grain temperature is cooled. When it is necessary to immediately discharge the grain from the machine, "discharge" on the basic pattern screen may be selected. The signal input to the power box 49 outputs a signal for starting the discharge conveyor 34, a signal for starting the discharge spirals 28, 28, and the like.
Moved to

As described above, regarding the CRT 46 screen,
On the basic pattern screen, a drying unit or a cooling tank to be operated, such as a stitching / drying operation, is selected by a pick operation, and then this operation state is selected from the character display unit h therebelow. for display, the operating state of the currently operating and configured to control "stop", i.e., easy operation as configured to display effect of "Chokomi stop" when selecting the Chokomi operation drying section b ₁ (Fig. 1
0). Note that a configuration in which a cancel switch is provided to cancel the setting may be adopted. The same applies to other operation states, for example, a drying operation, a discharging operation, and a moving operation,
"Stop drying", "Stop discharging", and "Stop moving" are displayed, respectively. In the case where all the parts are stopped, the basic pattern may be selected from any one of the following: embedding, drying, moving, discharging, and stopping.
