The tank 15 that stores the grains from the cargo receiving device 2 is provided with a lower limit level sensor 29 and an upper limit level sensor 30, which are linked to start signals of the cargo receiving process and the weighing process. In addition, the discharge port of the tank 15 communicates with the measuring instrument 16 via an openable / closable shutter 28. The weighing instrument 16 is equipped with a sample collection device (not shown), and a sample is taken out from the sample take-out bowl 31 and supplied to a self-testing device (not shown) to measure the moisture, variety, etc. of the sample. Various data are input to the control device 9, and the ownership ratio and the like are calculated. Further, a branch path 33 is connected to the discharge port of the weighing instrument 16 via an openable / closable shutter 32, and further, grain dropping basins 34 and 35 are connected to the branch path 33. The branch path 33 is provided with a switching valve 36 for switching the grain conveying direction.
[0016]
Further, the outlet of the grain loading culvert 34 faces a loading station 17 that waits for the empty container 19 via a disperser 37 that makes the dispersion of the grains uniform. The 35 outlets face the charging station 18 where the empty container 19 is put on standby with a disperser 38 for evenly dispersing the grain. The input stations 17 and 18 have a shape like a frame on which empty containers 19 and 19 are placed. Then, the empty container 19 is carried in and out from the standby rack 23 in the drying device 5 to the loading stations 17 and 18, and the grain loaded container 19 is loaded from the drying rack 22 in the drying device 5 into the loading stations 17 and 18. Unloading is performed by the transfer device 4.
[0017]
The specific configuration of the dispersers 37 and 38 interposed in the outlets of the grain dropping basins 34 and 35 is an inclined chute 39 and 40 for discharging the grain, and the inclined chute 39 and 40 are rotatably supported. In addition, the rotary shafts 41 and 42 in the vertical direction inserted into the downflow rods 34 and 35, cylindrical bearings 43 and 44 through which the rotary shafts 41 and 42 are inserted, and motors 45 and 46 as appropriate prime movers, The motor shafts 47 and 48 of the motors 45 and 46, and the transmission devices 49 and 50 that connect the motor shafts 47 and 48 and the rotary shafts 41 and 42, respectively. Reference numerals 51 and 52 denote gear boxes of the dispersers 37 and 38.
[0018]
As the transmission devices 49 and 50, a configuration in which a belt is wound around different diameter pulleys, a configuration using a transmission gear, and a method in which a stepping motor or the like is directly connected without using a transmission device can be considered. Then, a commercially available transmission gear called a Geneva gear was used. This Geneva gear will be described with reference to FIGS. The Geneva gear 53 includes a wheel gear 54 in which a plurality of concave holes 55 are formed in the circumferential direction, and a driver gear 57 in which a single pin 56 fitted in the concave hole 55 is provided upright. In the dispersing machine, the boss portion 58 is fitted to the rotating shafts 41 and 42 so that the wheel gear 54 is axially mounted, and the boss portion 59 is fitted to the driving shafts 47 and 48 so that the driver gear 57 is axially mounted. Disguise. Thereby, when the driving shafts 47 and 48 rotate, the pin 56 of the driver gear 57 is fitted into the concave hole 55 of the wheel gear 54, and the rotation of the wheel gear 54 is performed during the period in which the pin 56 is fitted into the concave hole 55. Will be stopped. That is, the driver gear 57 rotates continuously, but the wheel gear 54 rotates intermittently so as to repeat rotation and stop. That is, since the inclined chutes 39 and 40 rotate intermittently, there is no uneven dispersion of the grains in the container 19, and the container capacity can be made uniform.
[0019]
Next, the operation of the above configuration will be described.
[0020]
The harvested grain is received from the receiving hoppers 10 and 11, and it is confirmed whether or not the empty container 19 is waiting at the loading stations 17 and 18 before the receiving process.
[0021]
FIG. 6 is a flowchart showing an empty container transfer process to the loading stations 17 and 18. First, container information to be transferred from the standby rack 23 to the loading stations 17 and 18 is output to the control device 9, and empty container delivery data is created (step 1). Then, it is confirmed by the container confirmation sensor 62 whether or not the empty container 19 is waiting at the loading station 17 (left side in FIG. 3) (step 2). Similarly, it is confirmed by the container confirmation sensor 63 whether or not the empty container 19 is waiting at the loading station 18 (right side in FIG. 3) (step 3). If there is no empty container 19 in any of the loading stations 17 and 18, the empty container 19 is unloaded from the standby rack 23 by the transfer device 4 (Step 4), transferred to the loading station 17 (Step 5), and the like. Are also transferred to the loading station 18 (steps 6 and 7). Then, a receipt OK signal is output to the control device 9 and a receipt process is performed (step 8).
[0022]
When there is no empty container at the input station 17 and there is an empty container at the input station 18, the empty container 19 is unloaded from the standby rack 23 by the transfer device 4 (step 9), and transferred to only the input station 17 (step 9). Step 10).
Then, a receipt OK signal is output to the control device 9 and a receipt process is performed (step 8).
[0023]
If there is an empty container at the input station 17, it is confirmed whether an empty container 19 is present at the input station 18 (step 11). If the empty container 19 does not exist in the input station 18, the empty container 19 is unloaded from the standby rack 23 by the transfer device 4 (step 12), and transferred only to the input station 18 (step 13). Then, a receipt OK signal is output to the control device 9 and a receipt process is performed (step 8).
[0024]
When there is an empty container in both the loading stations 17 and 18, a cargo receiving OK signal is output to the control device 9 and a cargo receiving process is performed (step 8). As described above, the cargo receiving OK signal is output only when the empty container 19 exists in both the loading stations 17 and 18.
[0025]
Next, the receiving process will be described with reference to the receiving process flowchart of FIG. When the consignment OK signal is output to the control device 9 (step 20), it is further confirmed whether or not the empty container 19 exists in the loading station 17 (step 21). If there is an empty container 19 at the charging station 17, the switching valve 36 provided below the meter 16 is switched so that the grain flows down in the direction of the downfall 34 (step 22), and the disperser 37 on the downfall side 34 ( 3 is driven (step 23).
[0026]
If the empty container 19 does not exist in the input station 17, the process proceeds to step 38 to check whether or not the empty container 19 exists in the input station 18. When the empty container 19 does not exist in the charging station 17 and the empty container 19 exists in the charging station 18, the switching valve 36 provided below the measuring instrument 16 is switched so that the grain flows down in the direction of the flow-down rod 35 (step) 39), the disperser 38 (the upper left side in FIG. 3) on the downstream side 34 is driven (step 40).
[0027]
When the control of the switching valve 36 is completed, it is confirmed whether or not the measuring instrument 16 is normal (step 24). Subsequently, the load receiving shutters 60 and 61 are opened (step 25), and the harvested grains are sequentially loaded to receive the load. I will go. At this time, the grain is transported from the receiving hoppers 10 and 11 to the coarse selection machine 13 connected via the grain raising machine 12 and coarsely selected, and the grain raising machine 14 communicates with the grain input device 3 from the coarse selection machine 13. Are stored in the tank 15. Since the grain stored in the tank 15 can be measured by the measuring device 15 in the next process if it has a certain amount of capacity, it is monitored whether the weighing can be performed by the lower limit level sensor 29 at the bottom of the tank 15. (Step 26). At this time, the upper and lower level sensor 30 may control the opening and closing of the cargo receiving shutter so that the grain does not overflow from the tank 15 (steps 27 and 28).
[0028]
Next, weighing is started. First, it is confirmed that the shutter 32 at the bottom of the weighing instrument 16 is closed (step 29). Then, the shutter 28 at the bottom of the tank 15 is opened (step 30), and measurement is started (step 31). At this time, the weight is set in the weighing device 16 in advance so as to be weighed batchwise so that the weight can be accommodated in the container 19 (for example, 1 ton). In step 32, it is confirmed whether or not the measurement set value is reached. If it is the measurement set value, the shutter 28 at the bottom of the tank 15 is closed to complete the measurement (step 33). Next, the shutter 32 at the bottom of the measuring instrument 16 is opened in order to pay out the grains stored in the measuring instrument 16. As a result, the slag 34 (or 35) flows down and is introduced into the container 19 while being dispersed by the disperser 37 (or 38) (step 36). When the dispensing from the weighing instrument 16 into the container 19 is completed, the shutter 32 is closed (step 36), and the input of grain is completed (step 37).
[0029]
FIG. 8 is a flowchart of the container transfer process. When the grain has been put into the container 19 (step 50), a transfer OK signal is output to the control device 9 (step 51). Then, the transfer device 4 is transferred from the charging station 17 (or 18) to an arbitrary drying rack 22 in the drying device 5 (step 52). At the loading station, there is no container 19 placed on either of the reference numerals 17 or 18, so return to the empty container transfer process of FIG. 6 and check whether the empty container 19 is waiting. Then, a new empty container 19 is supplied.
[0030]
In this way, the empty container 19 is kept waiting for each of the plurality of input stations 17 and 18 before receiving the goods, the delivery of the grains of 19 to one empty container is completed, and then the switching operation of the switching valve 36 is performed. Then, the grain is discharged to the empty container 19 to the other side. Then, when the empty container 19 is not waiting at the charging station 17 (or 18), the supply of a new empty container 19 is performed, so that the delivery of the grains is not delayed, and the play time of the measuring instrument 16 is reduced. It does not occur, and it is possible to fully demonstrate the weighing ability.
[0031]
