And a residual grain presence / absence detecting means for detecting the presence / absence of grain in the paddy tank, a confirmation display and an input unit for confirming the execution of the discharge operation together with the grain residual state, and the discharge operation for driving and outputting to each operation unit by this confirmation input In the grain drying preparation system including an operation control device including means, a grain drying device including the grain drying unit 4 and the cooling tank 5, a grain huller, etc. Moving destination designating means for designating a destination to move the grain from the cooling tank to the grain drying section, and residual grain for detecting the presence or absence of grain in the destination cooling tank or grain drying section And no detection means is for the confirmation display and input unit confirms the execution of the discharge operation with grain remaining conditions, the configuration of the operation control device comprising a moving operation means for driving the output to the driving respective units by the confirmation input.

[0006]

[Effects of the Invention] For example, when performing a stake-in operation, when the stake-in destination is specified, it is judged by the residual grain presence / absence detection means whether or not there is any grain left in the stake-in destination. When a confirmation display prompting the user is displayed and the message that the sticking is OK is input, it is possible to newly add the added grain to the residual grain. Therefore, there is an effect that the additional extension can be easily selected when the work is interrupted.

The same applies to the discharge of grains or the exchange of grains between the grain drying section and the cooling tank.

It is used for own station determination when communication with a central control panel H described later is executed in a so-called multi-drop type line connection mode. For example, when "1 (unit)" is selected, each controller is controlled from the central control panel. It is configured such that the information signal related to "Unit No. 1" among the information signals to be received by the controller can be accepted by the controller and the drying control can be executed. At the same time, it is possible to select the "independent" mode in which the drying operation is performed separately from the central control panel, and the "inspection" mode in which the inspection of each operating part is executed.

Each layout of g is displayed graphically, and a display portion h for displaying operation switches or an abnormality is provided below the layout. The operation is in the form of a pick operation in which the user can directly select a desired driving state by directly touching the screen on which graphics or characters are displayed.

The power box 61 is composed of a programmable controller as a base, and receives a motor control signal from the central control board H for controlling a doctor 58, and convey system motors such as a stake elevator B, a stake conveyor D, and a discharge. It is a configuration capable of driving or stopping control of motors such as the conveyor E and the discharge elevator. In addition, the presence or absence of grain in the transport system and the input of a sensor system such as overcurrent detection are received and discharged to the control computer 58. The signals processed by the power box 61 are the controllers C ', C' ... of the dryers C, C ...
Unlike the signal under jurisdiction, the present invention relates to a common device such as the stake conveyor D.

The inside of the paddy tank F is No. 1 and N
o. The tank portion is divided into two layers, each tank portion is set to have substantially the same capacity as the cooling tank or the storage tank portion, and the remaining amount sensors 63 and 64 are provided below the inside of each tank portion. The operation of the above example will be described. In order to start the stake-in work, the drying device of the stake-in destination is selected by touching the "operation state / operation selection screen" (FIG.) Of the central control panel H (steps 101, 1).
02). When the No. 1 grain drying section is selected, that fact is displayed on the display section h, and the display section h
The screen moves to the "dryer operation screen" where the stop switch is displayed (step 103 in Fig. 8), and the operator touches the sticking switch part (step 104). Next, the presence or absence of grain in the designated destination, that is, the grain drying section of the first unit, is determined based on the detection information of the remaining amount sensors 50, 50 (step 105). As a result, if there is a grain, the screen is switched to the "prohibition / confirmation" screen (Fig. 11 (a)) (step 106), and then the "customer name input screen" and "grain name input screen" are displayed in response to the operator's "yes" response. When predetermined information is input in "(Step 107, 108)", the screen moves to the "Stick-in confirmation screen" (Fig. 11B) (Fig. 9, Step 1).
09), by returning to the above-mentioned "operating state / operation selection screen" by selecting "Yes" (step 110), the stake-in operation command is output, and the stake elevator B and the stake conveyor E are driven by motors (steps 111 to 111). 113) (Fig. 13).

At this time, by providing a swelling amount level sensor in the grain drying section 4, the grain level can be displayed so as to be gradually increased on the CRT display chart, which facilitates management. If there is no grain in step 105, step 107
Do the following. If the answer is "No" in step 106, the designation up to that point is cleared and the screen returns to the "operating state / operation selection screen".

In this way, at the time of stake-in, the presence or absence of grain is detected at the designated stake-in destination, and if grain is present, the mixture is expected to be mixed and the indication of stake-in prohibition is immediately displayed. It is possible to display the information and wait for the operator's instruction to perform additional stake-in. Therefore, when additional stake-in is performed due to interruption of the stake-in operation for some reason, it is convenient because grain separation does not occur.

Subsequently, the process proceeds to the drying operation. The operation at this time is to specify the grain drying section and to specify the grain drying section on the "operation state / operation selection screen" returned in step 110, as in the case of the loading operation. The operation is started by touching the drying switch (FIG. 10). Next, add the grains in the cooling tank to the paddy tank F.
The case of discharging into the air will be described with reference to the drawings.
First, a predetermined cooling tank is touch-operated from the "operation state / operation selection screen" (steps 201 and 202). Since the screen moves to the "dryer operation screen", the discharge switch section is touched (steps 203 and 204). The screen moves to the “destination confirmation screen” (FIG. 12A) (step 205) and selects “tank 1” or “tank 2” of the two layers (step 206). Remaining amount detection sensors 63 and 64 are provided in each layer of the paddy tank F, and the grain detection information of the designated tank is fetched to determine the presence or absence of grain (step 207). If there is grain, move to the "Emission Prohibition / Confirmation Screen" (Fig. 12 (b)) (step 208),
If the operator selects "Yes" on the screen, the screen returns to the "operation state / operation selection screen" (step 209), and the paddy tank F is switched and the discharge conveyor and the discharge elevator are driven and output (steps 210 to 21).
2) At the same time, the grain discharging operation from the designated cooling tank is started (step 213).

When there is no grain in step 207, the process proceeds to step 209 and the discharging operation is executed. In the above embodiment, when the grain is loaded and the grain is discharged, it is possible to perform the mixing process by checking the operator's confirmation while determining whether or not there is a grain destination grain, respectively. The same process can be performed when moving the dried grain from the grain drying unit 4 to the cooling tank 5, or conversely when moving the raw grain from the cooling tank 5 to the grain drying unit 4.

Further, when the grain should already be discharged to the grain and there is already a confirmation screen, when the caution is displayed, the customer name, the variety name, and the dry finish of the grain existing at the discharge destination are displayed in the display. The configuration of displaying (moisture value) is effective for the determination on the confirmation display screen. In addition, when communication is not possible due to disconnection of the connection line between the central control panel H and the drying section 4, the cooling tank 5, and the paddy tank F, etc., a "grain present" signal is detected by the remaining amount sensors 50, 50, etc. It is regarded as a logical input. By doing so, the tank empty information cannot be generated, and it is possible to prevent accidental grain loading.
