The rotation instructing means 4
3, the transfer order specified by the memory (RA
In addition to designating the source bin based on the carrying-in order stored in M), when there are a plurality of empty storage bins 10, the receiving order, that is, the order of the receiving bins is designated in a preset order.

In this rotation control, as shown in FIG. 4, the rotation procedure is set in advance according to the rotation procedure setting subroutine shown in FIG. 5, and based on the set procedure, the rotation procedure is shown in FIG. The rotation control is executed according to the rotation control subroutine. First, the setting of the rotation procedure will be described with reference to the flowchart shown in FIG.

Now, as shown in FIG.
In a state where ten storage bins 10 consisting of No. 10 are arranged, the bins are sequentially carried in from No. 1 bin and 7 bins of No. 7 bin.
The case where grain is carried in the bottle will be described.

In this case, the fact that the grain is carried in the No. 1 to No. 7 bins is stored in the memory (RAM), and the weights and varieties of the No. 1 to No. 7 bins are also stored. In this case, the No. 1 to No. 7 bins are the initial bins to be set.

Then, these bottles are displayed on display 4.
While viewing the image displayed by 8, the bin generation order is manually set in accordance with the binning designation procedure 45, for example, according to the loading order, and the order is stored in the bin generation cutout memory. Also, the designation of the receiving bin is manually set by the receiving bin specifying means 49 while viewing the image display on the display 48. Note that the order of the bins stored in the bin separation memory is that the destination bin specified in the order is taken in at the end of the bin order as the rotation order progresses. The stored bin order changes with the progress of the transfer order.

That is, when the No. 1 bin is designated as the source bin of rank 1, and the empty storage bin, ie, the No. 8 bin of the No. 8 bin to the No. 10 bin is designated as the destination bin, When the order is changed from Rank 1 to Rank 2 and the rank advances, the above No.
The eight bins are designated at the end of the above-described bin generation order as the bins of the take-in order of eight.

As described above, the procedures of the departure bin and the arrival bin are stored in the departure / departure bin procedure memory at each designated time, and all the storage bins No. 1 to No. 7 into which the grain is carried in are stored.
When the transfer of the grain from is completed, one rotation is completed, and according to the preset number of rotations,
For example, rotation control is performed a plurality of times according to the procedure shown in Table 1.

[0041]

[Table 1]

Thus, in FIG. 5, in step 1,
One bin (for example, No. 1 bin) is cut out from the bin separation memory in accordance with a preset bin order, and the data of the bin (No. 1) is read.

Then, in step 2, the image display on the display 48 is viewed and the empty bins (No. 8 to No. 1) are displayed.
0), a desired empty bin (for example, No. 8) is manually specified as a destination bin by the destination bin specifying means 49.

In the memory (RAM), the data of each bin (No. 1 to No. 10) at the time of performing the procedure setting, that is, the loading completion data, weight data, and type data of each bin serving as a source bin are stored. Data of empty or not in each bin serving as a destination bin, and when grain is carried in, its weight data and variety data are stored,
In step 3, it is first determined whether or not the designated bin is empty. In the case of NO, it is determined in step 4 whether or not the source and destination bins are different varieties. It is determined whether or not the arrival bin specified in the above is empty. Further, in step 6, it is determined whether or not the arrival bin is included in the series of receiving bins. It is determined whether or not the grain is in a line that is input from the receiving and weighing machine 5 via the top conveyor 12b. In the case of YES, that is, when the receiving bin is in the line on the receiving side, a caution alarm is issued in step 7. The data is output, and in the case of NO, since there is no error in the designation, the data of the designated destination bin is stored in the destination bin procedure memory in step 8.

When the designation of the destination bin in the transfer of rank 1 as described above is completed, the destination bin designated in this rank carries the grain by executing the transfer. The destination bin is taken in at the end of the source bin order stored in the source bin cutout memory, and the source bin specified in the order becomes empty by executing the transfer.
This departure bin is designated as the next-ranked destination bin.

When the transfer of the ranks is executed, the status of the bins and the destination bins specified by the ranks changes, that is, the specified bins become empty and the grain is carried into the specified destination bins. Therefore, in step 11, the data of the source bin and the destination bin is updated, and
The designated number C counted by the counter in 2 is set to C + 1,
In step 13, it is determined whether or not the designated number C is equal to or greater than a preset designated number M, that is, a designated number M based on a preset number of rotations. Update the original, specify the source bin of rank 2 (for example, No. 2 bin), return to step 2, repeat the process of rank 1,
The designation of the second and subsequent ranks is performed. If the designated bin is empty in step 3, an alarm indicating that the bin is empty is displayed in step 15 to urge the operator to correct the bin designation.

Also, if the type in the designated destination bin is different in step 4, an alarm indicating that the type is different is displayed in step 16 to urge the operator to correct the destination bin designation. Further, if the designated destination bin is not empty at step 5, it is determined at step 17 whether or not the designated destination bin is full. If NO, that is, if not, the designated destination bin weight W ₂ is determined at step 18. reads, if the sum is determined whether it exceeds the maximum (MAX) of the receiving space in the specified attachment bin NO the weight W ₁ of the Des bin in step 19, if that is acceptable grain of the Des bottle Returns to step 6.

Then, in the judgments of steps 17 and 19, Y
In the case of ES, a warning is displayed in steps 20 and 21 that the designated destination bin is unacceptable, and the operator is prompted to correct the destination bin designation.

As described above, the destination bin is designated, and the designated number C becomes equal to or larger than the designated number M set in advance, and if the determination in step 12 becomes YES, the rotation procedure setting ends in step 22.

Next, the control in the case where the rotation procedure is set as described above and the transfer is executed based on this procedure will be described with reference to the flowchart shown in FIG. First, in step 23, the procedure counter i is set to 0, and in step 24, the procedure counter i is set to i +
1, that is, i = 1.

Then, in step 25, the originating and destination bins of the first rank are read out from the procedure data stored in the destination / arrival bin procedure memory. Next, in step 26, the presence or absence of the procedure data is determined. If the procedure data does not exist, the designated number C is equal to or greater than the designated number M set as scheduled, and the rotation control may be terminated. Therefore, the rotation control is terminated in step 27, and NO In the case of (2), the data of the designated bin and the destination bin stored in the memory are confirmed in step 28, and it is determined in step 29 whether the designated destination bin can be received.

That is, whether or not there is any inconvenience when the procedure is executed according to the procedure data based on the data confirmed in step 28, for example, the arrival bin is empty when the procedure is set, It is determined whether or not the cargo has been received and the weight has been exceeded, or it has been impossible to receive the cargo due to the receipt of a different kind. If the cargo can be received, the transfer device is driven in step 30 and the No. . From one bin
Transfer to No. 8 bin is executed.

Then, in step 31, it is determined whether or not the No. 1 bin designated as the source bin is empty.
In step 32, it is determined in step 32 whether the No. 8 bin designated as the destination bin has become full. In the case of YES, the transfer device is stopped in step 33, and the transfer of rank 1 ends.

When the transfer of the rank 1 is completed, the data of the No. 8 bin designated as the destination bin is updated in step 32, and the process returns to step 24.

Then, in step 24, the procedure counter i is set to i + 1, that is, i = 2. In step 25, the source and destination bins of rank 2 are read from the procedure data stored in the destination and arrival bin procedure memory, and the same process as in rank 1 is performed. , The transfer of the order 2 is executed. That is, as shown in Table 1, No. 2 bin is designated as the outgoing bin, and No. 9 bin is designated as the destination bin, and the transfer of rank 2 is executed through the same process as rank 1. Then, thereafter, a plurality of rotation controls are executed based on the designated number of times set in advance, and when the rotation control set in advance in the rotation procedure setting subroutine ends, the procedure data is lost, so as described above. The rotation control is terminated based on the determination in step 26.

If the determination in step 29 is NO, that is, if the designated destination bin cannot be received, it is determined in step 35 whether or not there is an empty bin. The designation is transferred to this empty bin, and the process returns to step 30. If there is no empty bin, a warning is issued in step 37 that transfer is impossible, that is, rotation control is impossible. It ends.

In other words, if new grain is loaded from the receiving and weighing machine 5 after setting the procedure data to the destination bin specified based on the specified procedure data and it becomes unloadable, At 35, it is searched for empty storage bins 10 among the storage bins 10 not included in the procedure data. If there are empty bins, the designation of the destination bin is canceled at step 36, and the designation of the procedure data is canceled. The empty bin not included in the procedure data is transferred to the destination bin,
And the transfer is performed in the above-described process, and the transfer is not possible in step 37;
That is, it is determined that the rotation control is impossible, and an alarm is issued, and the rotation control is terminated. (Step 38) Further, when the rotation control is performed in the above embodiment, when Chakubin specifying the procedure data based is carried cereal having a predetermined weight W ₂ not empty bottles, on the wearing bottle The same applies when a new grain is carried in from the receiving and weighing machine 5 and the weight is over due to transfer to the receiving bin,
Even in this case, the transfer of the arrival bin is interrupted, an air storage bin 10 not included in the procedure data is searched, and this air bin is transferred to the arrival bin.

The transfer designation of the empty bin may be performed by predicting and avoiding the storage bin 10 serving as the receiving side when the receiving is performed from the receiving and weighing machine 5, or by setting the receiving side bin in advance and departure / arrival. When setting the bin designation procedure, it is preferable to designate a storage bin 10 other than the receiving bin as a destination bin.

As described above, empty storage bins 10 are sequentially designated as destination bins, and rotation of grain transfer is controlled while updating empty storage bins one after another, so that the number of storage bins is small. Even in this case, the transfer of the grain between the storage bins 10 can be rotation-controlled.
Therefore, there is no need for a transfer tank for transfer, which makes it possible to reduce equipment costs and to over-dry with a simple operation because there is no need to specify the departure and arrival bottles each time a worker performs transfer. Drying unevenness can be prevented without danger.

In the above embodiment, a case has been described in which grain is transferred and no new loading is performed during rotation control. However, when rotation control is performed and new grain is loaded, this rotation control transfer is performed. Empty storage bins not included in the procedure may be designated as destination bins, and storage bins to be carried in may be removed from rotation control, or they may be imported in anticipation of new loading during rotation control. Rotation control may be performed while avoiding the storage bin 10.

After the rotation control is completed, the storage bin 10 may be stored in the storage bin 10 incorporated in the transfer procedure at the time of the rotation control. However, since a plurality of storage bin groups are actually used, the storage bin 10 is distant from the loading side. The storage bin group may be transferred to such a storage bin group, or the rotation control may be sequentially performed in a storage bin group located far from the loading side. In the above-described embodiment, the air conditioning apparatus 31 is used to supply dehumidified air to the supply path 11.
However, the atmosphere may be used as it is without using the processing air.

[0062]

The present invention utilizes empty storage bins 10 among a plurality of storage bins 10 provided as described above, and sequentially designates the empty storage bins 10 as destination bins, and designates empty storage bins next. Rotation control was performed while updating to transfer and dry the grains to be dried.Therefore, as in the conventional example, a drying tank and a special exchange tank for transfer were provided in addition to the drying tank. The drying target can be transferred between the storage bins 10 even when the number of the empty storage bins 10 is small.

Accordingly, the equipment cost can be reduced, and it is not necessary to specify the departure bin and the destination bin each time an operator performs a transfer. When the transfer is controlled by a predetermined rotation, even if a new material to be dried is carried into the storage bin 10 designated as the destination bin and cannot be received, the destination bin cannot be received. The rotation control can be continued by changing the specification, and the interruption of the rotation control due to unacceptability can be reduced.
