Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a method for extracting grains from a plurality of preset storage bins based on the moisture content and variety of input grains. A grain receiver that automatically selects the most suitable storage bin for grain input and inputs the grain relates to an improvement of the device.

Conventional technology Grain receiving equipment such as rice centers is equipped with a large number of storage bins for storing grains, and the received grains are sorted according to attributes such as moisture content and variety, and storage bins corresponding to the sorting are carried out. It is designed to be put in and stored.

The grain receiving device generally consists of a grain receiving device A, a storage bin side device B1 having a plurality of storage bins, and a weighing device C disposed between them, as shown in FIG.
and a control device.

The receiving device A is equipped with a separator 102 for removing dust from the grains received from the receiving hopper 101.

Weighing device C is a preliminary hopper 1 that receives coarsely selected grains.
03a and a weighing machine 103b that measures the moisture content and weight of grains in a badge style.

Storage bin side device B includes a plurality of storage bins 10 for storing grains.
4a ~104. f, and a switching conveyance path 109 consisting of a bell 1 to a conveyor 108 and a horizontally movable belt conveyor 108-.

In addition, between each device is a belt conveyor 10 that roars along the grain conveyance path.
5 and packet conveyors 106, 107, etc. After receiving the cargo, the grains that have been roughly selected and measured by the rough sorting machine 102 and weighing machine 103b are transferred to the packet conveyor 10.
Belt conveyor 108 of conveyor path 109 switched via 7
further, via the belt conveyor 108,
The grains are dropped onto a belt conveyor 108' which can be positioned on a storage bin into which the grains are placed and which can move horizontally and change the direction of transport. Note that this belt conveyor 108- has previously completed positioning and horizontal movement onto the storage bin selected according to the attributes of the grains, and therefore the grains are conveyed in a predetermined transport direction and transferred to the belt conveyor 108-. A plurality of storage bins 104a selected from the end of the grain input section
~104-f.

Further, as the control device, a normal control device including a memory, a microprocessor, an input/output section, etc. is used.

In FIG. 12, reference numeral 110 indicates storage bins 104a to 10/
1. Bell 1 conveys the grains discharged from f to the next process
-It is a conveyor.

As shown in FIG. 13, the weighing device C receives grains from the coarse sorter 102 into a preliminary hopper 103a, and when the shutter 111 of this preliminary hopper 1038 is opened, the grains are fed into a weighing machine 103b. Ru. and the grain 1
When the weight reaches a preset amount and the weight scale 112 detects this, the shutter 111 of the preliminary hopper 1038 is opened.
is closed and the input of grains to the total ff1l*103b is stopped. At this time, the weight of the grains in the weighing machine is precisely weighed again using the weighing scale 112, while the moisture content is measured using the moisture meter 113, and these values are transmitted to the control device HD.

When these measurement processes are completed, the shutter 114 provided at the bottom of the total 111103b is opened and the grains for which one measurement process has been completed are discharged, and when the discharge is completed, the shutter 114 is opened.
is closed and the shutter 1 of the reserve hopper 1038 is closed again.
11 is opened and grains are put into the weighing machine 103b. Note that while the shutter 111 of the reserve popper 103a is closed, the grains discharged from the coarse sorter 102 are gradually stored in the reserve hopper 1038, but if the reserve hopper 103a becomes full during this operation, When this happens, the level detection sensor 115 installed above the preliminary hopper 1038 detects this, and the cargo receiving operation is temporarily stopped.

In such a configuration, when the attributes (variety, moisture content, etc.) of the grains in the receiving bin change due to a change in the tube opening, and the receiving bin is switched to the storage bin to which the grain should be put, in other words, the receiving bin is unable to accept grains with different attributes. When newly inputting from hopper 101,
Although it is necessary to move the belt conveyor 108' of the switching conveyance path 109 horizontally for positioning and to switch the conveying direction, it is necessary to move the belt conveyor 108' of the switching conveyance path 109 horizontally and to switch the conveying direction. Since the horizontal positioning movement is not performed instantaneously, the switching conveyance path 109 starts moving after selecting the input bin and horizontally moves for positioning to the target storage container 104, and as a result, the grain conveyance path is set. Usually 30 to 9 Q Se
It requires a waiting time of about c.

If the shutter 114 of the weighing machine 103b is opened during this waiting time, the grains will be mixed into the storage bin 104 whose attributes do not match, so the shutter 114 cannot be opened. It becomes impossible to continue working. In other words, in the conventional grain pre-receiving device, the grain input section of the switching conveyance path 109 for newly introduced grains is positioned on the storage bin 104 to be stored (the grain conveyance path is set). The problem is that the receiver cannot change the grain until after the grain processing is completed.

This is a major cause of traffic congestion at rice centers and the like where grains or grains with a wide variety of attributes are brought in during the harvest season. In addition, receiving goods is one of the reasons why it has not been possible to automate the work.

Problems to be Solved by the Invention Therefore, an object of the present invention is to provide a grain receiving device that can smoothly continue weighing operation even during grain conveyance path setting work associated with changing grains. .

Means to solve problems FIG. 1 is a block diagram of the means adopted by the invention.

The present invention provides a grain storage device equipped with a weighing device having a moisture meter between a cargo receiving device and a storage bin side device including a plurality of storage bins, in which the grain storage device is provided with a weighing device downstream of the weighing device. a storage bin data storage means a for storing preset moisture content and variety data in each of the plurality of storage bins; and the moisture meter. The storage into which the grain should be placed is determined based on the moisture content of the grain measured by the method, the variety code of the grain inputted by the data input means C, and the moisture percentage and variety data stored in the storage bin data storage means a. Storage bin selection means d for selecting a bin
and conveyance path setting means e for selecting a grain conveyance path from the adjustment tank to the storage bin by means of storage bin selection means d, and detecting that the grain conveyance path has been established by the conveyance path setting means e. The above-mentioned problem has been solved by providing a conveyance path setting confirmation means f for checking the conveyance path setting, and a shutter opening means q for opening the discharge shutter of the adjustment tank based on a confirmation signal from the conveyance path setting confirmation means f.

Function The storage bin data storage means a stores moisture content to be stored, product type data, etc. set in advance for each storage bin in association with each storage bin.

The storage bin selection means d selects the moisture content of the grains measured by the moisture meter of the weighing machine and the variety code of the grains inputted by the data input means C, from the storage bins stored in the storage bin data storage means a. The storage bin to which the grains should be placed is selected by comparing the moisture content and variety data for each bin.

When the storage bin selection is completed, the conveyance path setting means e sets a grain conveyance path from the discharge shutter of the adjustment tank to the storage bin selected by the storage bin selection means d.

The conveyance path setting confirmation means f confirms the establishment of the grain conveyance path, and the adjusting tank shutter release means q checks the discharge of grains that have been discharged from the weighing machine and temporarily stored in the adjustment tank during the conveyance path setting work. possible.

The operation of this embodiment will be explained below based on the processing flow chart of the system 1 weighing machine CPU 20a and the main CPU 29. Note that when data is stored in a register in each step, the register name is treated as a variable name.

First, Figure 5 (a) shows the processing of the system 1 weighing machine CPU 20a
), the system 1 weighing machine CPU 20a, which is initialized at the same time as the power is turned on (step 5101), receives the cargo from the operation panel 2.
The system enters a standby state waiting for data input from 6a (step 5102), and the receiver is placed on the operation panel 2 using the keyboard 24a.
When the data is entered from 6a, the consignee stores the year, month, and day in the variable N, the acceptance number in the variable Nc, and the personal code in the variable P.
In step 510, store the product code in variable Sn in step 510.
3) Immediately move belt conveyor 1a and packet conveyor 2.
The grain receiver starts transporting grains from the hopper 9a to the preliminary hopper 11a via the rough sorter 110a (step 5104). Next, level detection sensor LV2 is set to O.
If the answer is N, check whether the minimum amount of grains to start weighing has been put into the preliminary hopper 11a (step 5105), and if the level detection sensor LV2 is OFF and the amount of grains thrown is If the minimum amount to start weighing is not met,
Next, the cargo receiver checks whether the forced weighing switch on the operation panel 26a is ON (step 8106), and if the forced weighing switch is OFF, returns to step 5105 and processes from step $105 to step 5106. A loop is formed, and the minimum amount of grains to start weighing is put into the preliminary hopper 11a, and the level detection sensor LV2 is turned on.
Wait until . Next, the process moves to step 5107, and the cargo receiver waits until the weighing start switch on the operation panel 26a is turned on. Then, when the operator turns on the metering start switch, the process moves to step 8108 and starts processing related to metering.

Note that if the forced word volume switch is turned on in step 8106, 1tffi=
17 - Processing related to weighing from step 8108 onwards will be executed without waiting for the minimum starting amount of grains to be input.

In the processing related to weighing, the system 1 weighing machine CPU 20a
First, check whether the level detection sensor LV1 is OFF or not.
That is, it is checked whether the preliminary hopper 11a is full or not (step 8108), and the level detection sensor LV1 is OF.
If it is F and the preliminary hopper 11a is not full, grains are continued to be fed into the preliminary hopper 11a.

Next, it is determined whether the current input signal from the weight scale Mm of the weighing machine 12a indicates the input weight [0], that is, the grains in the weighing machine 12a that have finished weighing in the previous processing cycle. Step 51
11), the input signal from the ff1fa meter Mm is the input weight [
0] and the grains weighed last time in the weighing machine 12a have been completely discharged, then the preliminary hopper 1
The solenoid S1, which opens and closes the shutter 17 provided at the bottom of the shutter 18, is driven to open the shutter 17, and the loading of grains from the preliminary hopper 118 to the weighing machine 12a is started.Step S112), the timer king 1 detects the fraction. The time is set and started (step S113). Next, step 5114 compares the magnitude relationship between the weight currently detected by the weighing scale Mm of the weighing unit 112a and the set weighing weight (for example, 100Kg, 200Ky, etc. can be set).
), weight if' M The weight currently detected by m is full of the weight setting weight. If it is within the set time of timer T1, the process returns to step 5114 and the process returns to step 5.
A loop consisting of steps 114 and 5115 is formed, and in step 5114 the weight currently detected by weighing scale Mm reaches the weighing set weight, or in step 5115 the set time of timer T1 ends.

In step 5114, if the weight currently detected by the weight scale Mm reaches the weight setting, the solenoid S1 is turned off.
Step 511 closes the shutter 17 and prohibits the loading of grains from the preliminary hopper 11a to the weighing machine 12a.
6) Add 1 to the counter Z, which is the argument for the number of moisture content measurements (step 5117), and calculate the measured value of the moisture meter MW, that is,
The moisture content W (%) measured this time is added to the variable W that stores the cumulative moisture content (step $118), and step 512
Transition to 0.

On the other hand, if the set time of the timer T1 has expired in step 5115, the end amount detection time (the time sufficient for the weight of grains thrown into the total ff1li12a from the preliminary hopper 11a to reach the weighing set weight in normal conditions) is determined. ) has elapsed, the weight currently detected by the scale Mm is less than the set weighing weight, which means that the grains to be fed from the preliminary hopper 118 to the weighing machine 12a have already This means that it does not exist, and the current weighing is the final weighing process for the previous day, so the system 1 weighing machine CPU 20
Step a moves to step 5119, sets the measurement end flag F1, and moves to step 5120 without updating the counter Z that increments the number of moisture content measurements by η1 and measuring the moisture content while keeping the shutter 17 open. do.

In this way, the system 1 weighing machine CPU 20a, which has moved to step 5120, adds the weight m (K9) of the grains currently measured by the weight scale Mm to the variable M that stores the total weight of the grains (step 5120).

Next, in step 5121), it is checked whether the continuous processing flag F2 (described later) is set to cell i~, that is, whether the current weighing process is the first weighing process. If this is not the case and this is the first weighing process, then the main CPU 29 receives data 1 necessary for selecting the storage bin to be loaded, that is,
Step 5122) to send the device name 1 indicating that the data is being sent from the system 1 weighing machine 20a, the variety code 3n input in step 5102, and the moisture content W of the grain measured in step $118. 1st total fi)
A continuation processing flag F2 indicating that the processing has ended is set (step S123>).

= 21- Next, determine whether the level detection sensor lV3 is OFF or not.
That is, it is checked whether the adjustment tank 13a is full or not (step 5124), and the level detection sensor LV3 is turned off.
If the adjustment tank 13a is not full, the weighing machine 12
The solenoid S2, which opens and closes the shutter 18 provided at the bottom of the container a, is driven to open the shutter 18 and start charging the grains from the weighing machine 12a to the adjustment tank 13a (step 5125), and immediately set the shutter 18 open time. The timer T2 for monitoring the time is started at a predetermined time (step 8126).

Next, whether or not the set time of timer T2 has ended, that is,
Check whether the preset opening time of the shutter 18 for discharging grains from the weighing machine 12a to the adjustment tank 13a has ended (step 5127), and if the set time of the timer T1 has not ended, the shutter is closed. 18 remains open and waits for the set time of timer T2 to end.

When the set time of the timer T2 ends and the preset opening time of the shutter 18 for grain discharge ends, the solenoid S2 is immediately turned off and the shutter 18 is opened.
is closed, the grains put into the preliminary hopper 11a are stored in the weighing machine 12a, and the weighing process in the next processing cycle is enabled (step S128).

Next, check whether the conveyance path setting completion flag F3, which will be described later, has already been set, that is, whether the grain conveyance path from the outlet of the adjustment tank 13a to the storage bin 14a into which the grains are to be input has been established. Confirm whether or not (step S129
>.

If the transport path setting end flag F3 is not set,
Next, data 2 is sent from the main CPU 29, that is, from the outlet of the adjustment tank 13a to the storage bin 14 into which grains are to be input.
When the grain transport path leading to a has been set, the main CP
Check whether the position information of the storage bin 14a transmitted from U29 has been input (Step 5130), and if it has been input, set the variable j to indicate the storage bin 14a into which grains should be placed.
.

Position information P1 (1) indicating the system of 14b is added to the system in variable 1 (position information P2 indicating the bin number of the storage bin)
Remember (1) in step 3131), and set the conveyance path setting completion flag F3 to indicate that the conveyance path from the adjustment tank 13a to the storage bin 14a1 or 14b into which grains are to be introduced has been established (step 5132). , the solenoid S3 is driven to open the shutter 19 provided at the bottom of the adjustment tank 1.38, and the discharge of grains temporarily stored in the adjustment tank 13a is started (step 513).
3).

Furthermore, if the transport path setting end flag F3 is set in step 5129, steps 8130 to 5
Since the process up to step 133 has already been completed and the shutter 19 has been opened to allow the grain to be discharged from the adjustment tank 13a, the process immediately moves to step 5134.

On the other hand, if the conveyance path setting end flag F3 is not set in step 5129, and furthermore, the data from the main CPU 29 cannot be confirmed in step 5130,
Since the conveyance path from the outlet of the adjustment tank 13a to the storage bin 14a into which the grains are to be input has not yet been established,
The processes from step 8130 to step 5133 are not executed, and the shutter 19 of the adjustment tank 13a is kept closed to prohibit the discharge of grains, and the process moves to step 5134.

Then, in step 5134, it is checked whether the weighing end flag F1 is set, that is, whether all the weighing of the evening goods received this time has been completed, and if the weighing end flag F1 is not set, Next, timer T3 is set to a cushion time, that is, an interval time to absorb delays in the operation of each device or control system, and started (step 5135), and after waiting until the set time of timer T3 ends, (Step 8136), Step 5
The process returns to step 108 to start the next cycle of measurement processing.

In this way, the system 1 weighing machine CPU 20a performs steps 8108 - 5111 - step 5112 - step 5113 - step 5114 - (step S115
) - Step 8116 - Step 5117 - Step 8
The processes of 118-step 5120-step 5121 are repeatedly executed, but in step 5121, the continuation processing flag F2 is set after the end of the first measurement process, so data 1 transmission in step 5122 and step 5123 are performed.
Bypassing the 7-lag F2 set process, step $124 - step 5125 - step 8126 - step 5127 - step 5122 - step 8128
The processing leading up to is executed.

In the second cycle, if the conveyance path setting end flag F3 is still not confirmed in step 5129 and furthermore, the data from the main CPU is not confirmed in step 5130, that is, if the conveyance path setting end flag F3 is not confirmed in step 5130, If the settings are too high, the shutter 19 of the adjustment tank 13a is closed and the weighing process is performed twice, so the adjustment tank 13a has twice the capacity of the weighing machine 12a (however, the capacity of the adjustment tank 13a is twice that of the weighing machine 12a (however, the capacity ) will be input, and in step 8124 of the next processing cycle, the full state of the adjustment tank 13a will be detected by the level detection sensor 1-
Detected by V3, the processing from step 5125 onwards will not be executed, and the shutter 18 of the weighing machine 2a will no longer be opened, prohibiting the introduction of grains into the adjustment tank 13a, resulting in an accident in which the adjustment tank 13a overflows. is prevented. In addition, system 1 total f[cPU2
0a returns to step 5108, and from the next processing cycle onwards, the charging process will be executed only on the upstream side of the adjustment tank 13a.

And the total! Since the opening of the shutter 18 of the fi 12a is prohibited, after the second weighing process, the fi machine 12a
Since the grains are prevented from being discharged from the weighing machine 112a, the grains subjected to the third reduction process remain in the sugar bean 112a, and in the fourth cycle, the grain weight in the weighing machine 12a is reduced. The weight it M m to be detected detects the residual grains in the weighing t112a in step 5111, and the process from step 5112 onwards is not executed, and the shelf 1 of the preliminary hopper 11a
? Tsuta-17 will no longer be released and the random weight machine 12
It is prohibited to input grains into the tank 12a, thereby preventing an accident in which one machine 12a overflows. d3, system 1
The total UIC CPU 20a returns to step 5108, and from the next processing cycle onwards, the loading process will be executed only on the upstream side of the grinding machine 12a.

Then, by prohibiting the opening of the shutter 17 of the reserve hopper 11a, the discharge of grains from the reserve popper 11a is closed, so that the reserve hopper 11a is finally full, and in step 8108, the reserve hopper 11a is closed.
18 is detected by the level detection sensor 1-V1, the system 1 weighing machine CPU 20a stops driving the bell 1 to conveyor 1a and the bucket 1 to conveyor 2a, and prohibits the loading of grains into the preliminary hopper 11a. (Step 510
9) Prevent overflow of the spare hopper 11a, output an alarm output,
25a, etc. (step 511).
0), the operator manually performs fault recovery.

In this way, overflow of each device is prevented, but in this embodiment, abnormal conditions are sequentially detected from the downstream side of the grain flow, that is, from the adjustment tank 13a side, and the adjacent upstream Since opening of the shutter of the device on the side is prohibited, even if the device on the downstream side becomes full, the input of grains into the device on the upstream side is not hindered.

On the other hand, level detection sensor 1-■1 to LV3 and weight scale M
If the weighing end flag F1 is confirmed in step 5134 while m is performing smooth weighing operations without detecting any abnormal condition, this means that all weighing processing regarding the grains in this tube mouth has been completed. 1 city machine cPU20a,
The driving of bell 1 to conveyor 1a and bucket 1 to conveyor 2a is stopped (step 5137), and the final value Z of the number of moisture content measurements for this cylinder mouth counted in step 5117 is calculated in step $118. Based on the final value W (%) of the ratio, the average moisture content W/7 (
%) and store it in the variable W (step 5138),
Next, the level detection sensor LV4 of the adjustment tank 13a is set to O.
It is determined whether or not it is FF, and whether all the grains of the final badge of this tube mouth have been discharged from the adjustment tank 13a (step 5139), and when the completion of discharge is confirmed, the solenoid S3 is activated. is turned off and the discharge shutter 19 of the adjustment tank 13a is closed (step 8140>).

Note that the solenoid $1 that operates the shutter 17 of the spare popper 11a is normally closed, and the shutter 18 of the weighing unit 1j2a has already been closed in step 8128, so all the shutters have completed closing and are in the initial state. This means that he has returned to . Next, data 3, that is, the date of acceptance (N) and the acceptance number (Nc) read in step 5103 are sent to the main CPU 29.

Personal code (Pc), product code (Sn), step 8
The average moisture content (W) obtained in step 138, the total amount ffi (M) finally obtained in step 5120, step 51
Step 5141) , of which the date of acceptance (N
), acceptance number (Nc>, personal code (Pc), product code (Sn), average moisture content (W), total vehicle ffi (M) as shown in Figure 10, and print it out in the form 1~
After it has finished (step 5142), the process returns to step 5101, where it is initialized, and the receiving operation is performed. From 26a, the system enters a standby state in which it waits for the next data input from the tube mouth. In addition,
At the end of the measurement process, the device is always in a standby state in step S102, so it is possible to cut off the power as it is.

On the other hand, in FIG. 6 showing the processing of the main CPU 29,
The main CPU 29, which is initialized at the same time as the power is turned on (step 5201), performs each determination process from step 8202 to step 8206 to determine the system 1 total ff1i.
Whether or not data 1 is input from the cPU 20a or the system 2 meter hoisting machine CPU 20b (step 5202>, whether or not the selection request flag F4 or F5 described later is set, step 5203. Step 5204), the system 1 meter hoisting machine CPU20a or 2 systems ff1licPU20b
Step 5205>
1 Whether or not there is a completion signal input from the receiving () operation panel (
Step 5206) is monitored to determine whether each subroutine from step 8207 to step 5210 is to be executed.

First, in step 8202, the system 1 weighing machine CPU 20
The case where data 1 is input from a will be explained.

In step 5122 of FIG. 5 (a>) showing the processing of the system 1 weighing machine CPU 20a, the system 1 weighing machine CPU 20a that has finished the first weighing process receives data 1, that is, data transmitted from the system 1 weighing machine CPU 20a. When the main CPU 29 receives this information in step 5202, the main CPU 29 moves to input bin search subroutine A (step 5207). >.

The main CPU 29, which has moved to input bin search subroutine A as shown in FIG. 7, first determines whether the device name of input data 1 is 1 or not.
301), and the device name = 32- is 1, that is, if it is from the system 1 sugar meter CPU 20a, the device 1 selection request flag indicating that the system 1 is requested to receive the goods (device 1 selection request flag indicating that the system A is requested to receive the goods) F4 to Sera1
~ (step 5302), and a variable k indicating the device name is set to 1 (step 8303). On the other hand, if the input device name is not 1, that is, system 2 weighing machine CPU
If it is from 20b, the device 2 selection request flag F5 is set, indicating that the system 2 receiving is not requested to be received by the individual device A (step 5304), and the variable k indicating the device name is set to 2. Step 8305
).

Next, in step 5306, variables j (indicating the system of storage bins) and i (indicating the bin number of the storage bins), which serve as data search indicators, are set to 1. Step 8307), first
The upper limit moisture content Uw(j, i) and the lower limit moisture content Lw(j) are set in advance for each storage bin in random files R and F as shown in FIG.

i) 2 product code 5c (j, i), set weight Ms (j,
i), step 3308 to read each data of the current weight Mn (j, i Step 5309).
Step 5310) to determine whether the value of i exceeds 6, that is, whether it exceeds the number of storage bins provided in each prefecture. (If you press it, you will return to step 8308,
Based on the updated value of i, the data of the next storage bin is read and the moisture content W reaches the upper limit moisture UW(j
, i) to the lower limit moisture Lw(j, i) (step 5309). Also,
When the value of i reaches 6, storage bins (1,1) to (1,
If a suitable storage bin cannot be found even after the search for 6> is completed, the process moves to step 5312, resets the value of j to 2, returns to step 5307, and then searches for the storage bin of system 2 again in the same manner. Continue. When data that matches the moisture content W is read while repeating such processing, it is then determined whether the product code 3n sent from the system 1 weighing machine CPU 20a matches the product code 5c (j, i). step S3"13), and if they match, further,
Determine whether or not the value of set weight Ms (j, i) - current weight Mm (j, i) is greater than a predetermined value ε, that is, whether there is enough room to put grains into this storage bin. Step 8
314>, if there is room to input grains, this storage bin is selected as the input bin, and a variable P indicating the position information of the bin is selected.
The values of the data search index j and 1 are stored in i (k) (indicating the system) and P2 (k) (indicating the bin number), respectively, and the process returns to step 5203 of the main CPU processing flowchart 1 (step 5315). Note that if the value of k is 1, it indicates the position information of the input bin in response to the request of device 1, and if the value of k is 2, it indicates the position information of the input bin in response to the request of device 2.

The same applies to the case where data 1 is input from the system 2 weighing machine CPU 20b, so the explanation will be omitted.

Next, a case will be described in which it is confirmed in step 5203 that the selection request flag F4 is set.

Main C confirms that the selection request flag F4 is set and moves to the transport path setting subroutine B1 (step 8208).
In the conveyance path setting subroutine B1 as shown in FIG. In step S401'), it is determined whether or not the bin belongs to system 1. If it belongs to system 1, then the system 1 bin in use flag "6
is set (step 840).
2).

If the system 1 in-use flag F6 is not set, bell 1 to conveyors 3a, 3a are not in use and it is possible to input grain into the system 1 storage bin. starts horizontal movement to P2(1), that is, the position of the first bin number of system 1 selected in step 5315 of input bin search subroutine A (step 54
03), Step 5404> waits until reaching the target position is confirmed by the limit switch 31a.

Then, when reaching the target position is confirmed by the limit 1 to switch 31a, the drive of the belt conveyor 3a is stopped (step 5405), and next, whether or not the value of P2(1), that is, the bin number is greater than 3, is determined. If it is smaller than 3, the direction of rotation of the belt conveyor 3a is set to the left and grains are introduced from the left side of the belt conveyor 3a (Step 407), and if it is larger than 3, the rotation direction of the belt conveyor 3a is set to the left. The rotation direction of the bell 1-conveyor 3a is set to the right and grains are introduced from the right side of the belt conveyor 3a (step 84.08>. In this way, when the setting of the conveyance path in response to the request of the device 1 is completed, Next, reset the selection request flag F4 of device 1 to 1.
Also, since we set the conveyance path on the storage bin side of system 1 this time, we set the system 1 in-use 7 lag "6" to indicate that the system 1 bin is in use (step 84.09 >
. Next, the switching valve 4a is returned to its normal position (step 34).
10), drive the transfer device 5a, bucket 1 to conveyor 7a, and belt conveyor 8a (step 5411),
The weighing machine CPU 20 a receives data 2, that is, storage bin position information Pi (1) (indicating the system) and P2 (1) (
(indicating the storage bin number) (step 5422)
.

Note that the transmitted data 2 is processed in step S in the process of the system 1 weighing machine CPU 20a as shown in FIG. 5(b).
130, the system 1 weighing machine CPU 20a opens the shutter 19 of the storage tank 13a, and the grains discharged from the shutter 19 are transferred to the packet conveyor 2a,
Through the switching valve 4-a which has returned to its normal position, the belt conveyor 8a, and the belt conveyor 3a, the system P1 selected in step 5315 of the loaded garbage search subroutine A (
k).

It will be loaded into the storage bin (-1 in this case) of bin No. P2 (k>).On the other hand, step 5401 of the conveyance path setting subroutine B1 as shown in FIG. 8(a)
In step 5402, the variable P1(1) indicating the system of storage bins to be inputted is 1, and the system 1 bin in use flag F6 is set in step 5402.
is set, or if the variable Pi(1) indicating the system of storage bins to be inputted is 2 in step 5401, and the system 2 bin in use 7 lag F7 is set in step 5412. , because the transport paths overlap, device 1
cannot respond to the selection request flag F4 of device 1, and the main CPU 29 returns to the processing flow of the main CPU 29 as shown in FIG. 6, leaving the selection request flag F4 of device 1, and the previous measurement is completed. Then, the system 1 bin in use flag F6 or system 2 bin in use 7 lag F7 is reset. Note that steps 3412 to 3412 of the conveyance path setting subroutine B1 shown in FIG. 8(a)
The process leading to step 5421 is performed when the variable P1 (1) indicating the system of storage bins to be loaded is 2, that is, the storage container of system 2 is executed at step 5315 of the input bin search subroutine A.
This is the process corresponding to the case where the main CP is selected.
The operations of U29 are as described above from step 8402 to step 5.
Since the process is the same as that of step 411, the explanation regarding the flow will be omitted.

Also, in the case where the setting of the selection request flag F5 is confirmed in step 8204 of the main CPU processing flow, the same algorithm as in the case where the setting of the flag F4 is confirmed, so the explanation will be omitted.

Next, a case will be described in which data 3 is input from the system 1 measurement 11cPU 20a in step 5205 of the main CPU processing flow.

In step 5141 of FIG. 5(b) showing the processing of the system 1 weighing machine CPU 20a, the system 1 weighing machine CPU 20a confirms the discharge of the final badge of grain and inputs data 3, that is, the receiving date (N) and the receiving number. (C), individual code (Pc), variety code (Sn), average moisture content (%), total type fi (M
), storage bin position information (j, i), and device name (1) indicating that data is being sent from system 1, and when the main CPLI 29 receives this information in step 5205, the main CPU 29 Weighing end subroutine 40- Proceed to step C (step 8210). The main CP has transitioned to the measurement end subroutine C as shown in FIG.
The LI 29 first determines whether the device name of the input data 3 is 1 (step 5501), and if the device name is [1 piece and the receiving of the system 1 has finished weighing in the individual device A. If so, then it is determined whether the variable j1, ie, the value indicating the system in the storage bin position information, belongs to the system 1 (step 5502). If it is j-1 and the storage bin that has been loaded so far belongs to system 1, then the packet conveyor 7a.

Stop the transfer device 5a and belt conveyors 8a and 3a (step 5503), stop all conveyance paths from the outlet of the adjustment tank 13a of device 1 to the storage bin of system 1, and then set the system 1 bin in use flag F6 Reset system 1
Indicates that the bin is no longer in use (step 5504)
). Further, if the variable j is 2 in step 5502 and the storage bin that has been loaded so far belongs to system 2, the packet conveyor 7a, transfer device 6a, and belt conveyors 8b and 3b are stopped in step 5505. ), all conveyance paths from the outlet of the adjustment tank 13a of device 1 to the storage bin of system 2 are stopped, and then the system 2 bin in use flag F7 is reset to make the system 2 bin inactive. t (step 5506). On the other hand, step 55
If it is determined in step 01 that the device name is 2, the process from step 8507 to step 5509 or the process from step 8507 to step 8510 to step 5511 similarly drains the system from the outlet of adjustment tank 13b of device 2. All conveyance paths leading to the storage bins of system 1 or system 2 are stopped, and the system 1 bin in use flag F6 or the system 2 bin in use flag F7 is reset to indicate that the bins in each prefecture are no longer in use. Step 5509, Step 8
511).

In this way, each prefecture's bottle usage flags 1~
Then, the main CPU 29 executes the transport path setting processing subroutine 81 (step 5208) as shown in FIG.
and conveyance path setting processing subroutine B2 (step 8209
) can be executed again.

Next, the main CPU 29, which has proceeded to step 5512, accesses the random file R0, which stores the data of each storage bin, as shown in FIG.
, D, (j, i, n(j, i)), i.e., the nth (j, i)th storage bin that stores the personal data regarding the grains placed in bin NO1 of the storage bins of system j. Data 3 entered in step 5205 in the record, namely, date of acceptance (N), acceptance number (NOC), and personal code (
Pc), product code (Sn), average moisture content (W), and total weight ffi (M) are registered. Step 5512>, data indicating the current weight Mn(j.

The total weight fAM of the grains input this time is added to 1) to update the current weight. Step 5513), 1 is added to record No. n (j, i) that stores personal data and personal data is registered next time. After setting the desired record number (step 3514), the process returns to the main CP LJ processing flow shown in FIG.

In this embodiment, the process of the system 1 weighing machine CPU 20a is not shown, but as is clear from FIG. and the moisture content W, that is, the data necessary to select the storage bin into which the grains should be input, and the main CPU 29 searches the storage bins based on this information and selects the appropriate storage bin. Search subroutine A) moves bell 1 to conveyors 3a and 3b, positions them at the input position, determines the rotational direction of the conveyors, transfers devices 5a, 5b, 6a, 6b, packet conveyors 7a and 7b, and bells 1 to conveyors. 3a.

8b (convey path setting subroutine B1).
．． B2>, the grains should be input from the outlets of the adjustment tanks 13a and 13b, and after the setting of the grain conveyance path to the storage bin is completed, the outlet of the adjustment tanks is opened and the conveyance of the grains begins. (Steps 8130 to 5133).

Then, until the conveyance path setting is completed, system 1 (
System 2) Total fF [cPU 20a (b) can perform the weighing process up to three times under the control of Once the settings have been completed, even if grains are changed the day before, the receiver can continue to weigh the grains in the separate port, and there is no need to interrupt the receiving operation. In this example, the capacity of the adjustment tank is approximately twice the capacity for weighing, but the capacity of the adjustment tank depends on the relationship between the time required for searching and selecting storage bins, setting the transport route, and the time required for weighing processing. Needless to say, it may be set appropriately based on. In addition, in FIG. 5(b) showing the processing of the system 1 weighing machine CPU, the processing from step 8130 to step 8133, that is, the reception of data 2 from the main CPU 29 is confirmed and the shutter 1 of the adjustment tank 13a is
9 is released as an independent program as data 2.
It may also be executed by an interrupt input. Also, in step 8108, the level detection sensor 1 LV1 is set to the preliminary hopper 1.
When the full state of conveyor 1a is detected, the conveyor 18.2a is stopped (step 8109), an alarm is output (step 8110), and then the progress of the program is stopped and manual recovery is performed. , if data 2 is received by −45= interrupt input as described above, conveyor 1a
, 2a, check the input of data 2, and sequentially take out the grains from the downstream side, it is also possible to automatically perform failure recovery.

In the weighing process of grains for the final badge, moisture content is measured only for the final badge, taking into consideration the case where there is a small amount of remaining grains to be input, that is, there is a problem with the reliability f1 of moisture measurement by moisture calculation MW. Since this is not performed, it is possible to obtain a precise average moisture content based on a simple relationship between the cumulative moisture content W (%) and the counter Z indicating the number of moisture measurements.

In addition, as shown in the input bin search subroutine △, the selection of the storage bin into which the grains are to be inputted is not limited to the moisture content W1 variety Sn of the grains (steps 5309 and 5313), but also the selection of the storage bin to which the grains should be inputted. Since the relationship between the current type of grains that has already been input [tMn and the set weight MS that can be input (step 5314) is also determined, the grains in the storage bin will overflow.'': Such an accident will not occur. .

Furthermore, as shown in the conveyance path setting subroutine B1, if the storage bins selected for grain input belong to different systems, the system 1 and system 2 receivers input grain from side device A at the same time. It also allows for effective cargo receiving operations.

In addition, as shown in FIG. 11, the data for each storage bin, that is,
Upper limit moisture Uw, lower limit moisture LW, variety code Sc, set weight 1vis, current weight Mn, and personal data P, D regarding inputted grains (see Figure 10) are stored in the main CPU 2.
A CR7 display device or the like may be connected to 9 to display graphics so that it can be constantly monitored.

Effects of the Invention According to the present invention, it is possible to receive and process grains or grains at a separate pipe opening even during the conveyance path setting work associated with switching grains or grains, thereby interrupting the receiving work. Receiving goods can be carried out smoothly without the need for such operations.
