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

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.
A case will be described in which ten storage bins 10 composed of O.10 are provided, and the bins are sequentially loaded from the No. 1 bin and grain is loaded into seven bins of the No. 7 bin.

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

Then, these bottles are displayed on a 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 rank 1 source bin and the empty storage bin, that is, the No. 8 bin out of the No. 8 bin to the No. 10 bin is designated as the destination bin, Rank 1
From No. 8 to No. 8
The bin is designated as the bin of the take-in rank 8 at the end of the above-mentioned bin order.

Further, as described above, the procedures of the departure bin and the arrival bin are stored in the departure and arrival bin procedure memory each time designated, and all the bins from the storage bins No. 1 to NO. When the grain transfer is completed, one rotation is completed, and a plurality of rotation controls are performed, for example, according to a procedure shown in Table 1 according to a preset number of rotations.

[0036]

[Table 1]

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

In step 2, the empty bins (No. 8 to No. 1) are checked by looking at the image displayed on the display 48.
0), a desired empty bin (for example, No. 8) is manually designated as a destination bin by the destination bin designating means 49.

In the memory (RAM), the data of each bin (NO. 1 to NO. 10) at the time of setting the procedure, that is, the loading completion data, the weight data and the kind data of each bin as the source bin are stored. In each bin serving as a destination bin, data indicating whether the bin is empty or not, and when grain is carried in, weight data and type data are stored. In step 3, the designated bin is first empty. Is determined, if NO, it is determined in step 4 whether the source and destination bins are different varieties, and if NO, it is determined whether the destination bin specified in step 5 is empty. It is determined whether the receiving bin is included in the series of receiving bins in step 6, that is, when there is a receiving when the rotation is performed, the received grain is moved from the receiving weighing machine 5 to the top. It is determined whether or not the system is in the system inserted through the conveyor 12b. If YES, that is, if the destination bin is in the receiving system, a cautionary warning is output in step 7, and if 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 grain is carried in the destination bin specified in this rank 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 when the order is changed, the status of the source bin and the destination bin specified by the order is taken. Changes
That is, the designated bin is empty, and the grain is carried into the designated destination bin.
The data of the receiving bin is updated, and in step 11, the designated number C counted by the counter is set to C + 1. In step 12, the designated number C is the designated number M set in advance, that is, the designated number M based on the preset number of rotations. It is determined whether or not this is the case. If the determination is NO, in step 13 the bins are updated based on the bin order stored in the bin extraction memory, and the bin 2 of rank 2 (for example, No. 2 bin) is designated, and the process proceeds to step 2. Returning, the process of rank 1 is repeated, and designation of rank 2 and thereafter is performed. If the designated bin is empty in step 3, an alarm indicating that the bin is empty is displayed in step 14 to urge the operator to correct the bin designation.

Even 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 15 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 16 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 17. Is read, and it is determined in step 18 whether or not the sum of the weight W ₁ of the designated bin exceeds the maximum (MAX) of the receiving capacity of the designated bin, and if NO, that is, if the grain of the designated bin can be accepted. Returns to step 6.

Then, in the judgments of steps 16 and 18, Y
In the case of ES, in steps 19 and 20, a warning that the designated destination bin is unacceptable is displayed, 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 greater than the designated number M set in advance, and if the determination in step 12 becomes YES, the rotation procedure setting is ended in step 21.

Next, a description will be given, with reference to the flowchart shown in FIG. 6, of the control in the case where the transfer is executed based on this procedure after the rotation procedure is set as described above. First, in step 22, the procedure counter i is set to 0, and in step 23, the procedure counter i is set to i +
1, that is, i = 1.

Then, in step 24, the originating and destination bins of the first rank are read from the procedure data stored in the destination / arrival bin procedure memory. Next, in step 25, 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 larger than the designated number M set as planned, and the rotation control may be terminated. Therefore, the rotation control is terminated at step 26. In the case of (2), in step 27, the data of the designated source bin and destination bin stored in the memory is confirmed, and in step 28, it is determined whether or not the designated destination bin can be received.

That is, whether or not inconvenience occurs when the procedure is executed according to the procedure data based on the data confirmed at step 27, for example, the arrival bin is empty when the procedure is set, It is determined whether or not the receiving device is overweight due to receiving, or it is impossible to receive the product due to receiving a different type of product. If the receiving is possible, the transfer device is driven in step 29 and the NO designated in the order 1 is set. .1 bottle to N
The transfer to the O.8 bin is performed.

Then, in step 30, it is determined whether or not the No. 1 bin designated as the source bin is empty.
In the case of, it is determined in step 31 whether or not the No. 8 bin designated as the destination bin is full, and in the case of YES, the transfer device is stopped in step 32, and the transfer of rank 1 is completed.

When the transfer of rank 1 is completed, the data of the No. 8 bin designated as the destination bin is updated in step 33, and the process returns to step 23.

In step 23, the procedure counter i is set to i + 1, that is, i = 2. In step 24, the originating and destination bins of rank 2 are read out from the procedure data stored in the destination and arrival bin procedure memory, and , The transfer of the order 2 is executed. That is, as shown in Table 1, the No. 2 bin is designated as the outgoing bin, and the No. 9 bin is designated as the destination bin, and the transfer of rank 2 is performed through the same process as rank 1. After that, a plurality of rotation controls are executed based on the preset number of times, and when the preset rotation control in the rotation procedure setting subroutine is completed, the procedure data is lost, so as described above. Then, the rotation control is terminated based on the determination in step 25.

If the determination in step 28 is NO,
In other words, if the designated destination bin cannot be received, it is determined in step 34 whether there is an empty bin. If there is an empty bin, the destination bin designation is transferred to this empty bin in step 35 and the process proceeds to step 29. If there are no empty bottles, it is impossible to transfer in step 36, that is,
A warning that the rotation control is impossible is issued, and the rotation control is terminated in step 37.

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 the grain is transferred and no new carry-in is performed during the rotation control. However, when the rotation control is performed and a new grain is carried in, the transfer of the rotation control 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 data 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 used in practice, 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.

[0054]

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.

Therefore, 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. You can do it.
