Japanese Patent No. 2787877 Japanese Patent No. 3385878

However, the entry / exit management system described in Patent Document 2 described above is insufficient in exit management although it can manage the blowing capacity of the drying device in stages. That is, the rack type grain drying facility basically has a series of 24 cycles of a receiving process, a drying process, and a discharging process (operation of transferring grains in a container after drying to a storage device such as a silo). For example, when an operator shifts day and night, every time a container drying process on a predetermined rack shelf is completed even at night, the grain is manually discharged. However, there is a problem that labor costs for night work increase. In other words, because the grain drying equipment performs the drying process according to the next day's receiving schedule, the grains in the container after the drying process must be discharged and emptied by the next morning, and the grains brought in the next morning It is necessary to secure the necessary quantity of containers to receive the cargo.

In view of the above problems, the present invention takes advantage of the advantage of a rack-type grain drying facility in which, for example, a drying process is individually performed with a container having a capacity of 1 ton and flexible handling is possible for each consignment. It is a technical problem to provide an unloading management device that can unmanned the discharge operation and efficiently perform the discharge process.

In order to solve the above-mentioned problems, a first aspect of the present invention is a shelf-shaped grain drying device that stores a plurality of ventilated containers into which grains are charged and that dries the grains, and a subsequent stage of the grain drying apparatus. And a reversing device that discharges the grain by allowing the grain in the container to flow out of the container, a transporting means that transports the container between the reversing device and the grain drying device, Control means for centrally controlling each device by contacting the grain drying device, the reversing device and the conveying means, and managing the loading and unloading of a plurality of containers accommodated in the grain drying device and the discharging of the grains by the reversing device And a rack type grain drying facility comprising: an automatic discharge input means for reserving a discharge operation for a plurality of dried containers in the grain drying apparatus as discharge targets; Self When the specific information including the grain type, quality and the number of containers to be discharged is input from the discharge input means, the control means checks the inventory of the dried containers, and the grain drying device, the conveying means and the reversing means are It is constituted so that it may operate and may perform discharge operation about a plurality of dried containers.

In addition, when the dried container to be discharged becomes insufficient as a result of checking the inventory of the dried container, the control means regards the drying container with a short remaining time as a dried container and adds it to the discharged object. Technical measures were taken to do.

According to the first aspect of the present invention, specific information including the grain type, quality, and the number of containers to be discharged is input to the automatic discharge input means for reserving the discharge operation with the dried container as the discharge target. When the reservation is made, the control means checks the inventory of the dried containers and operates the grain drying device, the conveying means and the reversing device to continuously execute the discharging operation for a plurality of dried containers. For example, when the operator finishes daytime work and sets an automatic discharge reservation, the discharge operation is continuously performed unattended without going through the operator at night. Then, the discharged empty container is returned to the original drying rack, and when the operator goes to work the next morning, an empty container corresponding to the amount of grain received that day is secured.

According to a second aspect of the present invention, when the inventory of dried containers is confirmed, the control means dries a container that is being dried with a short remaining time when there are not enough dried containers to be discharged. Since it is regarded as a container and added to the discharge target, the discharge operation is not stopped even when the number of dried containers to be discharged is insufficient. In addition, since the container being dried is unattended to be discharged after drying, if you make a reservation for the discharge operation according to the next day's receiving schedule, the required quantity of empty containers will be secured the next morning. Will be.

A control device 9 for centrally controlling each device is provided in an operator room (not shown) of the rack type grain drying facility 1 and controls each device in the rack type grain drying facility as shown in FIG. A central control panel 37 is connected to a display panel 40, a mouse 51, and a communication system 38 for exchanging control commands with each device. As a menu screen on the display panel 40, as shown in FIG. 3, an icon 39a related to normal operation for starting or stopping each device such as receiving, transporting, drying, and reversing, and a container discharging operation are reserved. An input unit 39 including an icon 39b, a data processing icon 39c, a history display / form print icon 39d, and a result display / form print icon 39e is displayed.

When the normal operation icon 39a is clicked with the mouse 51, as shown in FIG. 4, the state in each drying rack 24 is displayed in different colors for each column number and column number. That is, the dry racks 24 shown in black from the left end shown in FIG. 4 are currently “drying”, and the dry racks 24 shown in light gray are currently “waiting for rotation”. The shaded drying racks 24 in the fifth column from the left end are currently “dried” but have not yet been reserved for discharge. In addition, the states of the drying racks 24 are “empty container”, “empty drying shelf”, “moisture abnormality shelf”, “waiting for drying”, “priority inversion”, “discharge reservation”, “entry prohibited shelf”, and “ Displayed in different colors as "Available standby shelves".

Next, the discharge operation reservation will be described with reference to FIGS. When the operator finishes daytime work and wants to set automatic discharge reservation for a plurality of containers 20 at night (step 1 in FIG. 6), by clicking the icon 39b (see FIG. 3) for reservation of discharge operation. Then, the automatic discharge reservation mode in which the plurality of containers 20 are sequentially discharged is set (step 2 in FIG. 6). When the automatic discharge reservation is not set, it is possible to perform a normal discharge operation from the result display / form print icon 39e (see FIG. 3), and the manual discharge processing of the single container 20 specified by the operator None (step 3 in FIG. 6), the address is specified and stored as normal discharge data (step 4 in FIG. 6).

In the automatic discharge reservation mode, first, the central control panel 37 automatically creates a list of “dried” containers based on the state diagram of the drying racks 24 shown in FIG. 4 (FIG. 5 (a)-(1 )), And check the inventory of the containers 20. Referring to the table of FIG. 5, it can be seen that the container 20 has moisture in the range of 14.5 to 15.0% and can be discharged for all containers. I can confirm.

Then, the operator himself sets work data (Step 5 in FIG. 6). As the work data to be set, there are “product type”, “quality”, “number of containers to be discharged”, “designation of operation of reversing devices 6a, 6b, 6c” and “designation of discharge destination silo 7”. By operating the five types of pull-down menus indicated by reference numerals 41 to 45, "product type", "quality", "number of containers to be discharged", "designation of reversing device operation", and "designation of discharge destination silo" in this order. Set it up. For example, “Product type” is “Hit down”, “Quality” is “Excellent product”, “Number of containers to be discharged” is “50 containers”, “Specifying operation of reversing device” is “Reversing device 6a is stopped, Reversing device” 6b and 6c are set to operate ”, and“ designation of discharge destination silo ”is set to“ inject into silo 1 ”, and this is set as discharge setting of one unit. Continuing as the second unit discharge setting, for example, “Koshihikari” for “Kyoto”, “Organic cultivation” for “Grade”, “20 containers” for “Number of containers to be discharged”, “Designation of reversing device operation” “Reversing device 6a is stopped, reversing devices 6b and 6c are operated”, and “designation of discharge destination silo” are set to “put into silo 2”. In this way, specific information including “variety” and the like may be set for each unit to be discharged, and settings may be made to discharge the number of containers corresponding to the amount of grain brought in the next morning.

When the setting of the work data is completed, the central control panel 37 searches the table shown in FIGS. 5A to 5A for a match with the set condition (step 6 in FIG. 6), and FIG. As shown in the table in (1), a list is created as the containers to be discharged.

Then, the set number of containers and the number of containers to be discharged (inventory of “dried” containers) are compared (step 7 in FIG. 6). The respective addresses of the containers 20 are identified and stored as automatic discharge data for sequentially discharging the plurality of containers 20 (step 8 in FIG. 6).

When the number of containers to be discharged is small (there is no “dry” container stock), a list of “drying” containers is automatically created based on the state diagram of the drying rack 24 shown in FIG. )-(3)), it is determined whether or not to add this to the number of containers to be discharged (step 9 in FIG. 6). The “drying” container list is obtained by extracting a plurality of containers 20 with a short remaining time for completion of drying, and becomes “dried” during the container discharging operation. Therefore, the list is added to the number of containers scheduled to be discharged. be able to. If the “drying” container is not added to the number of containers scheduled to be discharged, an error message for re-setting the “number of discharged containers” set in step 5 is output (step 10 in FIG. 6).

Hereinafter, the automatic discharge operation based on the “automatic discharge reservation data” set as described above by the operator will be described with reference to FIG. First, the central control panel 37 searches for automatic discharge reservation data (step 1) and confirms whether there is discharge work data that must be executed at present. Next, it is confirmed whether or not the stacker crane 4 is performing other loading / unloading operations such as loading from the receiving device 2 to the drying device 4 and loading from the drying device 4 to the reversing device 6 (step 2). When inside, wait for the end and go to the next step. When the work of the stacker crane 4 is finished, the reversing device 6, the cereal mills 30, 32, and the flow conveyor are based on the operation data of the operation of the reversing device and the designation of the discharge destination silo set in step 5 of FIG. An operation permission signal is output to 34 and 35, and a signal for performing a switching operation in a predetermined direction is output to the two-port switching valves 31 and 33 (step 3). Next, the delivery data consisting of the address of the container 20 and the drying rack 24 specified in step 8 of FIG. 6 is output to the stacker crane control unit 36 (step 4).

When the delivery data is input to the stacker crane control unit 36, the stacker crane 4 moves to the designated drying rack 24, and the crane unit 22 and the lift unit 23 deliver the predetermined container 20 (step 5). The delivered container 20 is transferred to the reversing device 6 and then reversed to discharge the grain (step 6), and is stored in a predetermined silo 7 via a cereal mill and a flow conveyor. It will be.

When the grain discharge is completed, a discharge end signal is output to the central control panel 37, and the empty container 20 is transferred from the reversing device 6 to the stacker crane 4 and returned to the original drying rack 24 (step 7).

Next, the completion of discharge of the container 20 is counted up (step 8), and it is determined whether or not the “number of containers to be discharged” set by the operator in step 5 of FIG. 6 has been reached (step 9). If the “number of containers to be discharged” has not been reached, the process returns to step 2 and the discharge operation similar to the above is repeatedly executed.

When the number of containers to be discharged is reached, it is determined whether or not all automatic discharge reservation data has been executed (step 10). If not, the process returns to step 1 to set discharge as the second unit. The automatic discharge reservation data or the like is searched and the discharge operation similar to the above is repeatedly executed.

As described above, according to the present embodiment, a shelf-like grain drying device 5 that stores a plurality of ventilated containers 20 filled with grains and drys the grains, and the grain drying device 5 Of the reversing device 6 which is arranged in the subsequent stage and discharges the grains by letting the grains in the containers 20 flow out of the containers, and between the reversing device 6 and the grain drying device 5.
