It is known as Japanese Patent Publication No.

In addition, the abnormality removing operation procedure is stored in a cassette tape, and when the above abnormality is detected, the abnormality removing operation procedure corresponding to the abnormal portion is played by voice from the cassette tape, and the operator follows the voice. A dryer with a voice announcement that operates a machine to eliminate abnormalities is disclosed in Japanese Patent Laid-Open No. 57-57
It has been proposed as No. 169587, but if it is only broadcast by voice, once it is overheard due to noise while the dryer is operating, etc., it will have to be reset and listened again, and it is troublesome to find the announcement start position. Moreover, there is a lot of lost time and it is not efficient. In addition, due to the restriction on the structure of the cassette tape, the information that can be broadcast is limited to simple information, so that it is not always possible to sufficiently convey all the operating procedures required for removing abnormalities.

Further, as a device for displaying necessary information using a rotary panel display, for example, a cooker in which a large number of display cards with a cooking menu is attached to a rotating member and the rotating member is rotationally driven by a pulse motor is disclosed. 57-212
No. 25 is proposed.

However, in this case, even with a simple operation that can be heard and understood, it is not possible to determine what the next work should be done without reading the card of the expandable display, and
When some kind of abnormality occurs, and when the information is provided only by the expansion display, it is possible to overlook the page change of the expansion display, and it is not enough to use it together with a warning such as a buzzer.

In addition, a display device provided with a recording medium on the message board and reproducing a matter corresponding to the displayed content of the displayed message board and displaying the sound when the message is displayed on the display window is disclosed in Japanese Utility Model Laid-Open No. 56-8.
It is known as Japanese Patent No. 3785.

Each address of the expandable display 12 indicating the rotation position of is stored.

FIG. 4 is a block diagram showing the configuration of the expandable display 12, 20 is a expandable display, and 21 is an interface circuit 15.
A control circuit 22 for the stepping motor SM which receives a signal from the display circuit 22 is a display position detector for detecting the display position of the expansion display 12. A command from the CPU 13 is transmitted via the interface circuit 15 to the stepping motor control circuit 2
When input to 1, the control circuit 21 drives the stepping motor SM to rotate the shaft 24 of the expandable display body 20 to release the panel 23 of the expandable display body 20 from the locking of the claw 25, Turn over one by one. On the other hand, the display position detector 22 detects the current value of the rotational position of the shaft 24, inputs it to the CPU 13 through the interface circuit 14, and when this current value and the command value from the CPU 13 match, the control circuit 21 causes the stepping motor to move. Stop the rotation of SM,
The panel 23, in which detailed information such as an abnormality removing operation procedure corresponding to the above-described abnormality signal is written, is arranged at the display position.

Next, the operation of the CPU 13 in this embodiment will be described with reference to the display control flow shown in FIG. 5 as the display selecting means stored in the memory 19.

When the switch on the operation panel 16 is turned on (step 10
1), the CPU 13 activates each drive unit 17 such as a motor through the interface circuit 15, selects the operation start position display address A ₁ from the memory 19, and outputs it to the voice synthesizer 11 and the expansion display 12. . The voice synthesizer 11 uses the information stored at the selected address A ₁ ,
For example, a message such as "Please perform a start-up inspection. Please press the monitor button after the inspection" is broadcast from the speaker 18. On the other hand, the stepping motor SM of the expansion display 12 is rotated, and when the operation start position read from the memory 19 and the detection position from the display position detector 22 match, the stepping motor SM stops.
At this time, the display contents written on the panel 23 of the unfoldable display body 20 describe the details of the start-up inspection items and finally that the monitor button is pushed (step 102).

Next, the CPU 13 determines whether the monitor button MB is ON (step 103), and if it is pressed, the memory 19 is pressed.
Address A ₂ is selected, the voice synthesizer 11 instructs by voice the selection operations of various processes such as sticking, drying, discharging, and the end of work, and a panel displaying the various processes is displayed on the expansion display. (Step 104). For example, while broadcasting that "Please select the operation to be performed from the contents of the expansion display 12 card," the expansion display 12 rotates as before and the address A ₂ The contents are displayed, and the operation to be performed next is displayed in detail as follows, for example.

1. Stake-in operation-set the type of grain and turn on the push-button switch.

2. Drying operation-Set the amount of swelling and the finishing moisture, and turn on the dry push button switch.

3. Discharge operation-turn on the discharge pushbutton switch.

4. Work done-power off.

On the other hand, the CPU 13 keeps the tension on the operation panel 16 during that period.
It is detected whether or not various processing switches such as drying and discharging or push button switches are operated (steps 105, 115, 148, 161), the common abnormality detection display processing shown in steps 163 to 190 is performed, and step 105 is performed again. The same process described below is repeatedly performed at fixed timings. This common abnormality detection display processing is the processing from steps 163 to 190 shown in FIG. 5, and is the sensor S ₁ , S ₂ , S ₃ for detecting the overload of the motor, the safety switch S ₄ , the automatic digestion device operation sensor S. _{5. It} detects whether or not the abnormality detection sensors such as ₅ , the seismic sensor S ₆ and the power failure sensor S ₇ are ON, and when they are ON, the motors and valves of the dryer are stopped and an alarm is issued. Therefore,
When the monitor switch is pressed, the voice synthesizer 11 broadcasts the occurrence of the abnormality, and instructs the location of the abnormality and the abnormality removing operation procedure by the expansion display.

For example, when the sensor S ₃ is ON, the "trouble has occurred. Please see the deployment type display device." And then broadcast, the display position of the expansion type display device 12 corresponding to the abnormality detection sensor that is ON The reading from the memory 19 is performed, and the stepping motor SM is rotated to flip the panel 23 until the display position is reached. Then, on the panel 23 at the corresponding display position, detailed information necessary at that time, that is, the abnormal portion and the abnormal elimination operation procedure and the fact that the monitor button is pressed after the abnormal elimination is finished, is described. Sensor S when detecting the motor heating of
_The expandable display 12 is rotated and displayed at a display position corresponding to ₃ . At this display position, it is displayed that the motor for the suction device 8 is overloaded, the inspection location and the like are displayed, and the abnormality removal operation procedure is displayed in detail. Admin
The abnormality removal operation should be performed according to this display.

When the abnormality is removed, the process returns to step 103 again.

The above is the common abnormality detection display processing, but if there is no abnormality, the dryer does not issue an alarm and stands by. Therefore, the operator follows the support displayed at the address A ₂ and, for example, performs a sticking operation. In this case, the grain selection switch of the operation panel 16 is set to the grain to be stretched and the stretch push button switch is pressed. Then, the CPU 13 detects the change of the push-in pushbutton switch (step 105), and since the push-in pushbutton switch is ON (step 107), the contents of the address A ₃ of the memory 19 are broadcast and displayed (step 105). 108). In other words, the voice synthesizer 11 broadcasts that the expansion display 12 is to be viewed, and the expansion display 12 displays details of precautions for sticking and that the stop button should be pressed when the sticking work is completed. To do. Then, the dryer performs grain filling, and during that time, the processes from step 105 to step 190 are performed at constant timings as described above.

That is, it is determined whether the push-in pushbutton switch has changed (step 105). In this case, since it has not changed, whether the push-in pushbutton switch is ON (step 1).
06) In this case, since it is ON, it is then detected whether or not the level sensor S ₁₂ for detecting the grain level in the tank T is ON (step 109), and if OFF, whether or not the stop button is pressed. (Step 113)
If not pressed, step 115 and subsequent steps 190
The processes up to step 190 are repeated again in the same manner. When the level sensor S ₁₂ is turned on (step 109), the motors are stopped and an alarm is issued (step 110). Then, when the monitor switch is pressed, the fact that the grain is full is broadcasted, and the development display 12 displays that the grain is full, details of the precautions and the monitor switch to be pressed (step 112). .

If the stop button is pressed before the level sensor S ₁₂ is turned on (step 113), the expansion display 12 is broadcast so that the expansion display 12 is displayed, and details of the stop precautions and the monitor are displayed. The switch is displayed to be pressed next (step 114).

Thus, Zhang inclusive operation is complete, then press monitor switch, according to the display described above at that time (display corresponding to the address A ₂₎ (step 104), Zhang inclusive amount, finishing moisture operation panel setting switch Then, when the dry push button switch is pressed, the CPU 13 detects the change and ON of the dry push button switch (step 115,
117), the address A _{6 of the} memory 19 is read, and the expandable display 12 is rotated to the position designated by the address A ₆ ,
Display details such as precautions for drying. Along with that CP
U13 temporarily stores the address A ₆ in a buffer register in the memory 19. It should be noted, are stored as "will start the blower" to the speech synthesis apparatus to the position of the address A _6. Next, the address B ₁ described in the buffer synthesizer as “amount of expansion” is stored in the buffer register, and the amount of expansion is read from the expansion amount setting switch. If it was a stone, CP
U13 is the memory address C _{10 of} "10".
And then "2 (d)" address C _{2 of} are stored in the respective buffer register address B ₂ of "stone". Further, the CPU 13 reads the finish moisture setting switch,
For example, if it is 20.5%, "finishing moisture",
Addresses B ₃ , C ₂₀ , C ₀ , C ₅ , and B ₄ of “20”, “. (Ten)”, “5”, and “%” are similarly stored in the buffer. Similarly, the CPU 13 reads the grain type setting switch, and if it is barley, for example, "grain type,
Start drying with barley. The address A ₇ which stores a "is stored in the buffer register (step 118).
Then, the CPU 13 sends each address stored in the buffer register to the speech synthesizer 11. Therefore, the voice synthesizer 11 broadcasts the driving condition from the speaker 18 with the information stored at each address.
In the case of the above example, "Begin blowing. 12 stones overhang,
Finish drying with 20.5% water, grain type and barley. Will be broadcast (step 119). If neither the monitor switch nor the stop button is pressed, an abnormality detection process during the drying operation (steps 125 to 14)
Perform 7). That is, when the dry push button switch is pressed, the ignition motor, the fuel pump ignition valve, etc. are turned on, but after this process, if the ignition sensor S ₁₁ for detecting the ignition of the burner 6 is not turned on, the motor is turned on. When the monitor is stopped and the alarm is issued (steps 125 and 126) and the monitor switch is pressed, the deployable display 12 is rotated to the misfire display position to broadcast the trouble occurrence and to display the misfire. (Steps 127, 12
8). If the ignition sensor S ₁₁ is ON, the CPU 13
Detects whether or not the sensor S ₈ for detecting heating, the sensor S ₉ for detecting digestion of the burner 6 and the sensor S ₁₀ for detecting oil shortage are ON, and further measures the signal from the moisture meter 4 for moisture measurement. From the processing loop, it is detected whether the water content has reached the set value, whether the water content meter 4 is judged to be out of order, or the like. Then, the sensor S ₈ to S ₁₀ without reaching to set the water without it turned ON, and if there moisture meter 4 also fails, then performs common abnormality detection display processing shown in FIG. 5. After this processing is completed, as shown in FIG. 5, the processing from step 105 onward is repeated again. In this case, since the dry push button switch has already been pressed and there is no change, the determination in steps 115 and 116 is made. The processing from step 120 onward is performed. If the monitor switch is pressed during this process, first, the remaining drying time is calculated from the value read from the moisture meter 4 (note that the remaining drying time is calculated and displayed even in the conventional dryer). Therefore, the processing at this point is omitted), and the value is, for example, 1
If the value is 2.5, the CPU 13 first moves the address B ₅ stored as “after drying is completed” to the buffer register, and then “10 (ju)”, “2 (d)”, “.
(Ten) "," 5 addresses B ₆ of (rubber) "of the respective address and" time after "is moved to the buffer register (step 121), and outputs it to the speech synthesizer," dried from the speaker 18 It will be finished after 12.5 hours. "
2). Then, when the stop button is pressed, the expansion display 12 is broadcast so as to be viewed, and the expansion display 12 displays precautions for stopping and pressing the monitor switch.
Further, when the sensors S _{8 to} S ₁₀ are turned on and an abnormality detection signal is output, the motors are stopped and an alarm is issued (step 1
30, 134, 138), next, when the monitor switch is pressed, the trouble occurrence is broadcast, and the expandable display 12 is rotated to the display position of the address A _{10 to} A ₁₂ corresponding to the sensor, and each abnormality is detected. The cause, details of the error removal operation procedure, etc. are displayed to press the monitor switch after error removal.

When the moisture meter 4 is determined to be out of order and a moisture meter abnormality detection signal is output, similar processing is performed, and the deployable display 1 is displayed.
2 shows in detail the failure of the moisture meter and the countermeasure for the failure. When the water content reaches the set value, the selected address is stored in the buffer register as in the previous case, and the "water content
It automatically stopped. ", The operation status is broadcasted by the speaker 18, and the notification that the set water content has been reached is displayed, and at the same time, the broadcast is displayed by pressing the monitor switch (step 14).
5-147).

In this way, when the dryer is stopped due to abnormality detection and achievement of water content, etc., after removing the abnormality, the monitor switch is pressed (step 103) and the detailed instructions displayed on the expansion display 12 are followed. The following processing may be performed.

Next, when the eject push button switch is pressed (step 1
46, 148), the CPU 13 calculates the discharge end time from the set amount of the swelling amount setting switch, and moves the address required for broadcasting to the buffer register according to the time, whereby, for example, "the discharge end is about 0. It will be 7 hours later. " And the expandable display 12
Is displayed on the display (step 151.
152). Also, the common abnormality detection display process is performed during the discharge period. Also, when the monitor switch or the stop button is pressed, the same processing as in the previous drying operation is performed as shown in FIG. When the discharge is completed and the discharge sensor S ₁₃ is turned off, the motors are stopped and an alarm is output. When the monitor button is pressed, the alarm is stopped, the discharge is completed, the expansion display 12 is broadcast to watch, and the expansion display 12 is displayed. Indicates that after handling, the monitor switch is pressed (steps 157 to 160).

Finally, when the power button is turned off, the expandable display 1
No. 2 is rotated to the position of address A ₀ , the handling is displayed on the dryer and the power button is displayed at the start of the operation, and the operation is completed.

In the above embodiment, the voice synthesizer is used as the voice storage generator, but a tape recorder or an audio disc device may be used.
