Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a receiving part for receiving granular grains delivered by a supplier, a conveying means for conveying the grains received in the receiving part, and a batch for weighing the weight of the grains conveyed by the conveying means. The present invention relates to a load receiving processing section in a grain processing facility provided with a weighing means of a type and a control means for managing operation so as to measure and manage the weight of the grain received in the receiving section for each cargo port.
[0002]
[Prior art]
The grain processing equipment configured as described above receives granular grains such as rice and wheat delivered by the supplier, measures the weight of the grains for each consignment while being transported by the transport means, and converts the grain into the accepted grains. However, in such a grain processing facility, a sample is taken from the grains weighed by the weighing means, and the yield (in the whole area) is measured. The ratio of normal grains) or the properties of grains such as moisture content is measured.
[0003]
And, for example, when measuring the yield of grains, samples are collected by the sample collecting device for a set number of times at a set cycle from the grains weighed by the batch type weighing means. The collected sample is automatically or manually transferred to a separate inspection device, and the measurement processing such as yield is performed by this inspection device. By collecting samples over a number of times and measuring properties such as yield with the samples, the average properties of the entire cargo port will be obtained, but conventionally, the set cycle is set to a predetermined fixed cycle. It was set.
[0004]
In addition, when measuring the moisture content of grains as a property, samples are sequentially collected from one grain of grain that is measured by the weighing means using the property measuring means, and The properties are measured until the number of samples reaches the set number. Conventionally, the set number collected for one grain of grain has been set to a predetermined constant value.
[0005]
[Problems to be solved by the invention]
By the way, in the case of granular grains such as rice and wheat to be processed by such a grain processing facility, they are transported due to the amount of moisture contained therein or the difference in frictional resistance of the grain surface. There are cases in which the degree of whether the material is easy to flow or difficult to flow, that is, the fluidity of the grains is different. And if the flowability of such grains is different, for example, after receiving at the receiving section, starting the conveyance and starting the receiving process for one loading port until the processing of that loading port is completed. The required time will be different. For example, when the cereal fluidity is high, the required time is shortened and the processing is completed in a relatively short time. However, when the cereal fluidity is low, the required time is increased and the processing time is long. Will take.
[0006]
However, in the above-described conventional configuration, when a sample for property measurement is collected by the sample collection device, a set cycle when a sample is repeatedly collected multiple times for a grain at one loading port is set at a predetermined cycle. Therefore, if the fluidity of the grains is different, it will not be possible to take the sample at the right time for the length of time required for weighing, and the sample will be taken evenly over the entire loading port. The average grain properties may not be accurately determined.
[0007]
For example, as the set cycle, the average measured value of the entire cargo port can be appropriately obtained even if the grain to be processed has the lowest fluidity, in other words, the grain that takes the longest time. If a long time is set and a grain with high fluidity is carried in, the sample will be sampled over a set number of times at a set period set to a long time, even though the required time is reduced. Therefore, there is a risk that the processing will end before sampling is performed a preset number of times, and the average grain properties over the entire consignment may not be measured.
On the other hand, if the set cycle is set to a short time, when a low-fluid grain is processed, the sampling cycle is too short for the long time required. Measurement is performed only when the grain in the first half of the consignment is being transported for receiving, and measurement processing is not performed when the grain in the second half of the consignment is being transported. As a result, there is a risk that the average grain properties over the entire loading port cannot be measured.
[0008]
In addition, when the property measuring means as described above is provided, the properties of a predetermined set number of samples are measured. It may become impossible to accurately determine the characteristics of typical grains.
For example, a sample for measuring the properties so that the average properties of the entire cargo outlet can be appropriately obtained even if the grains to be processed have the lowest fluidity, in other words, the grains that take the longest time. If the set number of items is set in advance, when grains with high fluidity have been delivered, the set time is set assuming a long required time even though the required time is shortened as described above. Since the properties of a number of samples are measured, the number of samples for measurement may be insufficient, and the properties may not be appropriately measured as an average value over the entire cargo port. Also, if the set number is set to a large value assuming that the fluidity is high, the number of samples for measurement will increase too much when the grain with low fluidity is processed, and the entire loading port There is a possibility that the property cannot be appropriately measured as an average value over the range.
[0009]
The present invention has been made paying attention to such a point, and the purpose of the present invention is to obtain an average over the entire loading port even in the case where a grain with high fluidity or a grain with low fluidity exists as a processing target. The object of the present invention is to provide a consignment processing unit in a grain processing facility that can appropriately measure grain properties.
[0010]
[Means for Solving the Problems]
The cargo receiving processing unit in the grain processing facility according to claim 1 includes: a receiving unit that receives the granular grain delivered by the supplier; a transport unit that transports the grain received by the receiving unit; and the transport unit A batch type weighing means for weighing the weight of the conveyed grain, and a control means for managing the operation so as to measure and manage the weight of the grain received in the receiving portion for each cargo port. There,
A sample collecting means for collecting a sample from the grains weighed by the weighing means for measuring the properties of the grain, and a fluidity measuring means for measuring the fluidity of the grain are provided,
When the control means manages the operation of the sample collecting means so as to execute the sampling of the sample at a set cycle, and the set cycle is high based on detection information of the fluidity measuring means. This is characterized in that it is configured to change in a shorter state than when fluidity is low.
[0011]
That is, when the grain receiving process is started, the grain received by the receiving unit is transported by the transport means toward the batch-type weighing means, and the batch-type weighing means measures the weight of the conveyed grain. become. On the other hand, the fluidity measuring means measures the fluidity of the grain, and the setting cycle is changed in a state where the measured fluidity of the grain is higher than that when the fluidity is low. Then, the sample collecting means collects a sample from the grains weighed by the weighing means for measuring the properties of the grains, and at that time, every set period changed based on the fluidity of the grains. A sample will be taken.
[0012]
In other words, the time required from the start of receiving processing to the end of processing for a single consignment grain is shorter when the grain fluidity is high and when the grain fluidity is low. Is longer, but if the grain fluidity measured by the fluidity measuring means is high and the required time is long, a sample is taken every long set period, and if the grain fluidity is low and the required time is short, the sample is short Samples are collected at each set cycle, and the grain properties are measured by the collected samples.
As a result, grain samples can be sampled almost evenly across the consignment, depending on the length of time that varies due to the grain fluidity, even if the grain fluidity may vary. Thus, the grain properties are measured by the collected sample. By measuring the properties of the grain with the sample collected almost uniformly over the whole cargo port, it becomes possible to measure the properties of the grain almost evenly over the whole cargo port.
[0013]
The fluidity of the grain is a degree of whether it is easy to flow or difficult to flow when being transported, for example, the grain is stored in the grain storage space for weighing in the batch type weighing means. The length of storage time until the set target weight of grain is stored after the start of storage of the grain corresponds to the fluidity of the grain. In addition to this storage time, the length of the discharge time from the start of grain discharge from the grain storage space for weighing to the discharge of all grains, and the size of the transport load when transporting grains Etc. correspond to the fluidity of grains.
[0014]
Therefore, even if there are grains with high or low fluidity to be processed, by measuring the grain properties almost evenly throughout the consignment, It has become possible to provide a cargo receiving processing unit in a grain processing facility that can appropriately measure properties.
[0015]
The receipt processing part in the grain processing facility according to claim 2 is the detection information of the fluidity measurement unit according to claim 1, wherein the control unit determines an execution time of the sample collection for each set period of the sample collection unit. Based on the above, the fluidity is changed so that the fluidity is changed in a shorter state than when the fluidity is low.
[0016]
That is, in the case of grains with high fluidity measured by the fluidity measuring means, in other words, grains that are easy to flow when transported, sampling is performed in a short time, so the yield can be efficiently achieved in a short time. Thus, it is possible to reliably collect a set amount of grains necessary for measuring the properties of the grains. In addition, in the case of grains with low fluidity measured by the fluidity measuring means, in other words, grains that are difficult to flow when transported, a sample amount is taken over a long period of time to obtain the set amount necessary for measurement. Can be harvested and a suitable means for carrying out claim 1 is obtained.
[0017]
The cargo receiving processing unit in the grain processing facility according to claim 3 is a receiving unit that receives the granular grain delivered by the supplier, a transport unit that transports the grain received by the receiving unit, and a transport unit that transports the grain. Batch type weighing means for measuring the weight of the grain to be received, and control means for managing the operation so that the weight of the grain received in the receiving part is measured and managed for each cargo port. And
A property measuring means for sequentially collecting samples from the grains weighed by the weighing means and measuring the properties of the sequentially collected samples until the number of samples reaches a set number, and the fluidity of the grains Fluidity measuring means for measuring
The control means manages the operation of the property measuring means so as to execute sample collection and property measurement for a set number of samples, and sets the set number of samples for measuring the property to the fluidity. Based on the detection information of the measuring means, it is configured to change in a state where the fluidity is higher than when the fluidity is lower than when the fluidity is low.
[0018]
That is, when the grain receiving process is started, the grain received by the receiving unit is transported by the transport means toward the batch-type weighing means, and the batch-type weighing means measures the weight of the conveyed grain. become. On the other hand, the fluidity of the grain is measured by the fluidity measuring means, and the property of the grain is measured by the property measuring means in a state where the fluidity of the measured grain is higher than when the fluidity is low. The set number of samples at the time is changed. Then, the property measuring means sequentially collects samples from the grains weighed by the batch type weighing means, and measures the properties of the sequentially collected samples until the number of samples reaches the set number. become.
[0019]
In other words, the time required from the start of receiving processing to the end of processing for a single consignment grain is shorter when the grain fluidity is high and when the grain fluidity is low. Is longer, but when the fluidity of the grain measured by the fluidity measuring means is high and the required time is short, the set number of samples when measuring the properties increases, and the fluidity of the grain is low and the required time is low. When the length of the sample is long, the set number of samples when measuring the properties is reduced.
When the flow rate of grains is high and the required time is short, the number of samples when measuring properties increases, so that the number of samples in the entire consignment collected by shortening the required time is not insufficient, It is possible to appropriately measure the average properties over the entire cargo port. In addition, when the flowability of grains is low and the required time is long, the number of samples when measuring the properties decreases, so that the total number of samples collected at the consignment as a whole increases due to the increase of the required time. Therefore, it is possible to appropriately measure the average property over the entire cargo port.
[0020]
The fluidity of the grain is a degree of whether it is easy to flow or difficult to flow when being transported, for example, the grain is stored in the grain storage space for weighing in the batch type weighing means. The length of storage time until the set target weight of grain is stored after the start of storage of the grain corresponds to the fluidity of the grain. In addition to this storage time, the length of the discharge time from the start of grain discharge from the grain storage space for weighing to the discharge of all grains, and the size of the transport load when transporting grains Etc. correspond to the fluidity of grains.
[0021]
Therefore, even when there are grains with high fluidity and grains with low fluidity as the processing target, the cargo receiving facility at the grain processing facility can appropriately measure the average grain properties at the consignment. We have been able to provide a processing unit.
[0022]
5. The cargo receiving processing unit in the grain processing facility according to claim 4, wherein the receiving unit receives the granular grain delivered by the supplier, the transporting means for transporting the grain received by the receiving unit, and transported by the transporting means. Batch type weighing means for measuring the weight of the grain to be received, and control means for managing the operation so that the weight of the grain received in the receiving part is measured and managed for each cargo port. The property measuring means for sequentially collecting samples from the grains weighed by the weighing means and measuring the properties of the sequentially collected samples until the set measurement time elapses, and the flow of the grains Fluidity measuring means for measuring properties, and the control means operates the property measuring means so as to cause sampling and property measurement of the sample to be executed. Managing and changing the set measurement time in a state where the fluidity is higher when the fluidity is higher than when the fluidity is lower based on the detection information of the fluidity measuring means. Features.
[0023]
That is, when the grain receiving process is started, the grain received by the receiving unit is transported by the transport means toward the batch-type weighing means, and the batch-type weighing means measures the weight of the conveyed grain. become. On the other hand, the fluidity measuring means measures the fluidity of the grain, and the set measurement time is changed in a state where the fluidity of the measured grain is higher than that when the fluidity is low.
[0024]
In other words, the time required from the start of receiving processing to the end of processing for a single consignment grain is shorter when the grain fluidity is high and when the grain fluidity is low. However, when the grain fluidity measured by the fluidity measurement means is high and the required time is short, the set measurement time for measuring the properties of the samples collected sequentially becomes long. When the number of samples increases and the flowability of grains is low and the required time is long, the set measurement time for measuring the properties of the samples collected sequentially becomes short, so the number of samples when measuring properties decreases. .
Therefore, when the flowability of grains is high and the required time is short, the number of samples for measuring properties increases, so even if the required time is shortened, there is no shortage of samples collected at the entire cargo port. It is possible to appropriately measure the average properties over the entire cargo port. In addition, when the flowability of grains is low and the required time is long, the number of samples when measuring the properties decreases, so that the total number of samples collected at the consignment as a whole increases due to the increase of the required time. Therefore, it is possible to appropriately measure the average property over the entire cargo port.
[0025]
The fluidity of the grain is a degree of whether it is easy to flow or difficult to flow when being transported, for example, the grain is stored in the grain storage space for weighing in the batch type weighing means. The length of storage time until the set target weight of grain is stored after the start of storage of the grain corresponds to the fluidity of the grain. In addition to this storage time, the length of the discharge time from the start of grain discharge from the grain storage space for weighing to the discharge of all grains, and the size of the transport load when transporting grains Etc. correspond to the fluidity of grains.
[0026]
Therefore, even when there are grains with high fluidity and grains with low fluidity as the processing target, the cargo receiving facility at the grain processing facility can appropriately measure the average grain properties at the consignment. We have been able to provide a processing unit.
[0027]
The cargo receiving processing unit in the grain processing facility according to claim 5 is the cargo receiving processing unit according to any one of claims 1 to 4, wherein the fluidity measuring unit starts storing grains in the grain storing space for measurement in the batch type measuring unit. The storage time until the set target weight of grain is stored is measured as the fluidity of the grain, and the fluidity is higher when the storage time is short than when the storage time is long. It is characterized by being.
[0028]
That is, the storage time from the start of grain storage to the grain storage space for weighing in the batch type weighing means until the grain of the set target weight is stored is measured as the fluidity of the grain. When the storage time is short, the fluidity is high, and when the storage time is long, the fluidity is low. Such storage time corresponds to the fluidity of the grain, and the control means manages the operation of the weighing means, so that a special measuring processing device is provided to make the configuration complicated. Can be easily measured, and a suitable means for carrying out any one of claims 1 to 4 can be obtained.
[0029]
The receipt processing part in the grain processing facility according to claim 6 is provided with a moisture content measuring means for measuring the moisture content of the grain according to claim 5, and the fluidity measuring means uses the fluidity measured by the fluidity measuring means. Based on the moisture content measured by the moisture measuring means, the higher the moisture content, the lower the correction.
[0030]
That is, the moisture content of the particulate matter affects the viscosity of the particulate matter. If the viscosity is high, the fluidity of the particulate matter becomes low, but if the moisture content of the particulate matter is high, the viscosity becomes high. Therefore, the moisture content of the particulate matter is measured by the moisture measurement means, and the fluidity measured based on the measurement result is corrected to be lower as the moisture content is higher. It becomes possible to measure, and means suitable for carrying out claim 5 is obtained.
[0031]

Grains are stored in one of the storage bins 19 by the moving belt conveyor 22 that is configured to be capable of changing the position of the supply position along the conveying direction. Then, the grains stored in the storage bin 19 and dried are discharged by blowing air from the fan 24, supplied to the hulling adjustment unit 3 by the lateral feed conveyor 23 and each conveyance conveyor, and further through the shipping unit 4. It is supposed to be shipped.
In this processing facility, a plurality of producers individually carry grain into the receiving part, but each producer accepts the entire amount of grain carried in as one cargo outlet, and the total weight and grain of each grain are accepted. Grain properties such as moisture content and yield are measured and the measurement results are reported to the producer.
[0034]
Next, the configuration of the load receiving weighing machine 11 will be described.
As shown in FIG. 2, the load receiving weighing machine 11 serves as a weighing hopper 25 for temporarily storing the grains discharged from the sorting machine 10 and the grains from the feeding hopper 25 as weighing means. A weighing hopper 27 for weighing using the load cell 26 is arranged side by side in a vertical direction while being supported by the frame body 28. The load cell 26 supports the load in a cantilevered state with a pair of front and rear support arms 34 on the weighing hopper 27 and measures the weight of the grains stored in the weighing hopper 27 in such a supported state. It is provided in a state supported by the frame body 28 so that it can be made.
[0035]
The lower opening of the supply hopper 25 opens and closes supply as a granular material supply means that can be switched between a supply operation state in which stored grains are supplied in a fall state and a supply stop state in which the supply is stopped. A mechanism 29 is provided.
[0036]
As shown in FIG. 5, the supply opening / closing mechanism 29 has two supply mechanisms that can be switched between a closed state for closing the lower opening of the supply hopper 25 and an open state for opening the lower opening. Gates 30 and 31 are provided to be opened and closed by driving air cylinders 32 and 33, respectively. When the two gates 30 and 31 are both switched to the closed state, the lower opening of the supply hopper 25 is closed and the supply of grain is stopped. When one small supply gate 30 is kept closed and the other large supply gate 31 is switched to the open state, the lower opening is opened by about half, so that the grain is supplied in a small amount. Small supply state. Then, when the two gates 30 and 31 are both switched to the open state, the lower opening of the supply hopper 25 is fully opened, and a large supply state in which grain is supplied in a large amount is supplied. Therefore, the supply operation state can be switched between two states, a small supply state and a large supply state.
[0037]
In addition, a discharge opening / closing mechanism 35 that opens and closes the lower discharge portion of the weighing hopper 27 to switch between a storage state and a discharge state is provided. The discharge opening / closing mechanism 35 includes a discharge gate 36 that can be swung between a closed state in which a lower discharge portion of the weighing hopper 27 is closed and an open state in which the lower discharge portion is opened, and an air cylinder that can be operated to switch the discharge gate 36. 37. That is, by switching the discharge gate 36 to the closed state, the storage state in which the grains are stored in the weighing hopper 27 is established, and by switching the discharge gate 36 to the open state, the grains stored in the weighing hopper 27 are stored. It becomes the discharge state to discharge.
[0038]
The side wall 38 of the supply hopper 25 is provided with a sample collection device 39 as sample collection means for collecting a sample from the grains weighed by the load receiving weighing machine 11. As shown in FIGS. 3 and 4, the sample collection device 39 includes a cylindrical body 40 that is disposed in a state of passing through the side wall 38 and facing one opening into the supply hopper 25, and the cylindrical body 40. The movable body 41 is movably installed, the air cylinder 42 that slides the movable body 41, and the sample chute 43 that is connected to the bottom of the cylindrical body 40. An accommodation space U for accommodating the sample is formed in a state of penetrating from the upper surface to the lower surface and in an inclined posture state in which the upper opening is positioned on the inner side of the hopper with respect to the lower opening.
[0039]
In the sample collecting device 39, the air cylinder 42 is operated, as shown in FIG. 3A, the sample receiving state in which the tip of the moving body 41 protrudes from the opening of the cylindrical body 40, and FIG. As shown in FIG. 5, a grain sample can be collected by switching to the retracted state in which the entire moving body 41 is fitted into the tubular body 40.
That is, in the sample receiving state, the upper opening portion of the storage space U faces the supply hopper 25 and the lower opening portion is closed at the bottom of the cylindrical body 40 so that the grains are stored in the storage space U. Be contained. Then, with the movement of the moving body 41, the grain on the upper part is scraped off at the upper edge of the opening in the tubular body 40, so that a predetermined amount of grain is held in the accommodation space U. Switch to retirement state.
Then, a predetermined amount of grain held in a state where the lower opening of the accommodation space U faces the sample chute 43 is discharged to the sample chute 43.
The sample discharged from the sample chute 43 is collected by a collection box 44, and an operator takes it by hand to an inspection device (not shown) prepared separately to inspect the yield of grains. For example, the sample may be transferred to the inspection apparatus automatically by an automatic transfer apparatus using air transfer or the like instead of the manual operation.
[0040]
The weighing hopper 27 is provided with a moisture measuring device 45 as a moisture content measuring means for taking in each grain in the hopper and measuring its moisture content. As shown in FIG. 6, the moisture measuring device 45 has a device body 45 a attached to the outer side of the side wall 46 of the weighing hopper 27, and a grain feeding lateral feed screw 45 b is inserted into the hopper through an insertion hole formed in the side wall 46. An introduction chute 45c for entering the inside and guiding the grain to the transverse feed screw 45b is attached by being fastened together with the apparatus main body 45a with a screw across the side wall 46. As shown in FIG. 7, the lateral feed screw 45b is configured to feed the grain guided by the introduction chute 45c into the screw groove 47 and feed it laterally one by one into the apparatus main body 45a. As shown in FIG. 8, the apparatus main body 45 a is configured such that the grains taken inside one by one are crushed by sandwiching the grains one by one with a pair of rollers 48 that also serve as electrodes, and the electric resistance between the rollers 48. It is comprised with the single grain moisture meter of the well-known structure which measures the moisture content of a grain based on the electrical signal corresponding to the change of. Further, the grains collected one by one by the lateral feed screw 45b overflow and are discharged downward from the lower discharge port 49 when the moisture measurement processing by the roller 48 is finished. Yes. Note that the number of measured samples can be determined by the control device H described later based on the electrical signal.
The moisture measuring device 45 measures the moisture content that is the property of the grain, and sequentially takes samples from the grain in the weighing hopper 27, that is, the grain that is being weighed by the load receiving weighing machine 11, This corresponds to the property measuring means SK for measuring the properties of the sequentially collected samples until the number of samples reaches a set number.
[0041]
As shown in FIG. 2, the load receiving weighing machine 11 is provided with a control device H using a microcomputer. The control device H puts the discharge opening / closing mechanism 35 into the storage state and the supply opening / closing mechanism 29. Measurement storage processing for storing grains in the storage space in the supply operation state, and when the weight of the set target value is measured by the load cell 26 in the measurement storage processing, the supply opening / closing mechanism 29 is in a supply stop state and discharged The discharge process for bringing the open / close mechanism 35 into the discharge state is a mode in which the measurement storage process is started as the grain discharge is completed in the discharge process, and the target set in the load cell 26 in the measurement storage process When the end amount specific time elapses before the value weight is weighed, the discharge process is started and executed repeatedly. Further, the measurement value measured by the load cell 26 immediately before the discharge opening / closing mechanism 35 is set to the discharge state is set as the actual measurement value.
[0042]
More specifically, the grains received by the supplier are sequentially conveyed from the load receiving hopper 5 by the load receiving conveyor 6 and the first lifting conveyor 5, and are supplied for the supply through the flow rate adjusting tank 8 and the coarse selector 9. It is supplied to the hopper 25 and temporarily stored. When the grain is supplied to the supply hopper 25 and the weighing operation is started, the measurement storage process and the discharge process as described above are repeatedly executed to obtain the total weight for each cargo port, and the moisture content of the grain is measured and the yield inspection is performed. Samples are collected for the purpose.
[0043]
To explain the weight measurement, the weighing hopper 27 is configured to be able to store a little more grain than the set target value weight (about 200 kg), and weighs each set target value weight. Batch-type weighing is performed while repeating this several times, and the total weight (for example, about several hundred kilograms to about 2,000 kilograms) of the consignment is obtained from the cumulative value of the measured weights. Further, when the last weighing is performed at the cargo port, only the grain (weight) smaller than the set target value is supplied to the weighing hopper 27. At this time, the measured value of the load cell 26 is The set target value is never reached. Accordingly, when the end amount specific time elapses before the weight of the set target value is weighed by the load cell 26, the discharge process is started and the weighing process at the cargo port is ended.
[0044]
And the said control apparatus H performs the fluidity | liquidity measurement process which measures the fluidity | liquidity of a grain. That is, in the measurement storage process, the storage time from the start of grain storage to the grain storage space for measurement until the storage of the grain of the set target weight is measured as the fluidity of the grain, and the storage time The fluidity is higher when the length is shorter than when the length is shorter.
[0045]
Further, the control device H manages the operation of the sample collection device 39 so that the sample collection is executed at the sample collection set cycle, and the sample collection set cycle is set to the flow measurement process. Based on the result, the fluidity is changed so that the fluidity is shorter when the fluidity is lower than when the fluidity is low. Further, the sample collection device 39 is configured to change the sample collection execution time for each set period in such a manner that the grain fluidity is longer when the grain fluidity is higher than when the grain fluidity is lower.
[0046]
Further, the control device H manages the operation of the moisture measuring device 45 so as to perform sample collection and measurement of moisture for a set number of samples, and the number of samples for measuring moisture is measured by the fluidity measurement. Based on the result of the process, the fluidity is changed so as to increase when the fluidity is higher than when the fluidity is low.
[0047]
Therefore, the control device 100 that manages the operation of the cargo receiving processing unit 1 and the fluidity measurement means 101 that measures the fluidity of the grain are configured using the control device H.
[0048]
Hereinafter, based on a control flowchart and a time chart, the control operation | movement by the control apparatus H is demonstrated concretely. In this control operation, the grain conveyance control from the load receiving hopper 5 is not mentioned, but it is assumed that the grain is appropriately supplied to the supply hopper 25.
As shown in FIGS. 9 and 10, when the supply of the grain to the supply hopper 25 is started and the weighing is started, the sample collection setting period Ts1 and the sample collection execution time Ts2 and moisture in the sample collection device 39 are measured. An initial value stored in advance as a standard value is set for each of the number M of samples to be measured (step 1).
When the standby interval time T0 has elapsed, it is checked whether or not the measured value Wx of the load cell 26 is near zero (steps 2 and 3). That is, it is checked whether or not the measurement value Wx is within a predetermined allowable range with respect to zero. If it is not near zero, an abnormal process such as notifying that the load cell 26 is abnormal is performed (step 4).
If the weighing value Wx of the load cell 26 is near zero, the weighing value Wx of the load cell 26 at that time is reset as a value corresponding to zero (step 5), and the large supply gate 31 in the supply opening / closing mechanism 29 is reset. Then, both the small supply gate 30 are switched to the open state to be in the supply operation state (large supply state), and the grain is stored in the storage space (step 6). At this time, the discharge gate 36 is closed in advance. At this time, the time counting by the timer counter is started (step 7).
[0049]
Then, as shown in FIG. 14, the measured value Wx of the load cell 26 increases with the supply, but the measured value Wx is not less than the set value W1 for small supply set as a value slightly lower than the set target value W2. Then, the large supply gate 31 is closed to switch to the small supply state (steps 8 and 9). When the measured value Wx becomes equal to or greater than the set target value W2, the small supply gate 30 is also closed and switched to the supply stop state (steps 10 and 11).
[0050]
When switching to the supply stop state in this way, the time counting by the timer counter is stopped, and the storage time Tc from when the storage of the grain is started until the grain of the set target weight is stored is measured ( Step 12). This storage time Tc corresponds to the fluidity of the grain indicating the degree of whether the grain is easy to flow or difficult to flow, and when the storage time Tc is short, it is longer. This means that the liquidity is high.
[0051]
When the grain supply is performed in the large supply state, the time counting by the timer counter is stopped when the end amount specific time Th has passed before the measured value Wx becomes the set value W1 for small supply or more. Then, the process proceeds to end amount processing as will be described later (steps 13, 14, and 15). Similarly, in the small supply state, when the specified amount of time Th elapses before the measured value Wx becomes equal to or greater than the set target value W2, the time counting by the timer counter is stopped and the process proceeds to the amount of amount process (step 16). 17).
[0052]
When the weighing value Wx exceeds the set target value W2 and switches to the supply stop state and the weighing balance time Tb for stabilizing the output has elapsed, the weighing value Wx measured at the load cell 26 at that time is changed to the actual weighing value. Are stored in a memory (not shown) (steps 18 and 19), the discharge gate 36 is switched to the open state, the grain is discharged, and when the discharge is completed, the discharge gate 36 is closed (steps 20, 21, and 22).
[0053]
Then, based on the measurement information in the fluidity measurement process, specifically, the measurement result of the storage time Tc, the sample collection setting period Ts1 and the sample collection execution time Ts2 in the sample collection device 39, the moisture measurement device 45 The sample collection execution time Tw2 and the number M of samples for measuring moisture are changed (step 23). In other words, the setting period Ts1 for sampling is changed in a state in which the fluidity of the grain is shorter when the fluidity of the grain is lower than when the fluidity is low. Specifically, as shown in FIG. 17, the set period Ts1 is continuously generated based on a correlation indicating a preset linear change between the length (fluidity) of the storage time Tc and the set period Ts1. Change in a state that changes automatically. Further, the sample collection execution time Ts2 in the sample collection device 39 is changed in the same manner as the set cycle Ts1 so that the grain fluidity is shorter when the grain fluidity is higher than when the grain fluidity is lower (see FIG. 15). And the setting number M of the sample which measures a water | moisture content in the water | moisture-content measuring apparatus 45 is changed in the state which increases when the fluidity | liquidity of a grain is higher than when the fluidity | liquidity is low. Specifically, as shown in FIG. 16, the set number M is continuously generated based on a correlation indicating a preset linear change between the length (fluidity) of the storage time Tc and the set number M. Change in a state that changes automatically. Further, when moisture measurement as described later is performed, the fluidity is corrected to be lower as the moisture content is higher based on the measured value of the moisture content of the grain measured (step 24, 25).
[0054]
Then, the process returns to step 2 and the processes in steps 2 to 23 are repeated a plurality of times until it is detected in step 8 and step 10 that the end amount specific time Th has elapsed. Then, when it is detected in step 8 or step 10 that the end amount specific time Th has elapsed, the end amount processing as shown in FIG. 11 is executed (step 15).
[0055]
Next, the end amount processing will be described. When the end amount specifying time Th has passed in the large supply state, the large supply gate 31 and the small supply gate 30 are switched to the closed state by switching both to the closed state, and the end amount is specified in the small supply state. When the time Th has elapsed, the small supply gate 30 is switched to the closed state by switching to the closed state (step 151). When the measurement balance time Tb elapses after switching to the supply stop state, the measurement value Wx measured by the load cell 26 at that time is read as an actual measurement value and stored in a memory (not shown) (steps 152 and 153). Then, a plurality of actual measurement values measured and stored a plurality of times after the start of measurement are summed, and the total weight Wt at the loading port is calculated and stored, and the measurement of the moisture measurement performed a plurality of times is performed. The average moisture obtained by averaging the values is obtained and stored (step 154), the discharge gate 36 is switched to the open state, and the grain is discharged. When the discharge is completed, the discharge gate 36 is closed and the weighing is finished (step 155). 156, 157).
[0056]
Next, the moisture measurement process will be described.
This moisture measurement process is performed only once for the grain at the beginning of the weighing of the grain at one loading port, and is performed as shown in the time chart of FIG. That is, when the supply of the grain to the supply hopper 25 is started and the weighing process as described above is started, the transverse feed screw is started to start sampling of the grain, and the sample is collected by sequentially collecting the samples. Is measured one by one and the moisture content is measured while crushing the grains with the roller 40 (steps 31 and 32). Then, the measurement process is performed until the number N of samples whose moisture has been measured reaches the set number M set as described above, and when the set number M is reached, the moisture measurement is terminated and the operation of the transverse feed screw is performed. Stop sampling to stop sampling (steps 33 and 34).
[0057]
Next, sample collection processing by the sample collection device 39 will be described.
The sample collection process by the sample collection device 39 is repeatedly performed at set intervals by timer interruption. That is, as shown in FIG. 13, it is determined whether or not the timing for sample collection has passed after the set period Ts1 for sample collection has elapsed since the previous measurement by the timer interruption (step 41). When it is determined that the sample collection device 39 has been detected, the sample collection device 39 is switched to the sample receiving state to place the sample in the accommodation space of the moving body 41 (step 42). When the sample collection execution time Ts2 set as described above elapses after the process is started, the sample collection device 39 is switched to the retreated state and the sample collection process is terminated (steps 43 and 44). . The collected sample is collected in the collection box through the sample chute 43.
[0058]
Thus, according to the fluidity of the grain, by changing and adjusting the set period Ts1 when collecting a sample for yield measurement, the execution time Ts2 of sample collection, and the measurement number M when performing moisture measurement, It is possible to appropriately measure the average grain properties over the entire loading port.
[0059]
[Another embodiment]
Next, another embodiment will be listed.
[0060]
(1) In the above embodiment, based on the measurement information in the fluidity measurement process, each of the sample collection setting period Ts1 and sample collection execution time Ts2 in the sample collection device 39, and the number M of samples for measuring moisture However, instead of such a configuration, it may be configured as described in the following (A) to (D).
(A) A configuration in which only the sample collection setting period Ts1 in the sample collection device 39 is changed, and other measurement conditions are not changed.
(B) A configuration in which the sample collection setting period Ts1 and sample collection execution time Ts2 in the sample collection device 39 are changed, and other measurement conditions are not changed.
(C) A configuration in which only the number M of samples in the moisture measuring device is changed, and other measurement conditions are not changed.
(D) A configuration in which the number M of samples in the moisture measuring device is changed, and other measurement conditions are not changed.
[0061]
(2) In the above embodiment, the configuration in which the moisture measuring device as the property measuring unit changes the set number of samples for measuring moisture based on the detection information of the fluidity measuring unit is exemplified. Instead, it may be configured as follows.
In other words, the property measuring means sequentially collects samples from the grains weighed by the batch-type weighing means and measures the properties of the sequentially collected samples until the set measurement time elapses. The control unit manages the operation of the property measuring unit so that the sample is collected and the property is measured for the sample, and the set measurement time is changed based on the detection information of the fluidity measuring unit. It is configured to change in a longer state when the liquidity is higher than when the liquidity is low.
[0062]
In this embodiment, the configuration of the measurement process in the moisture measuring device as the property measuring unit and the configuration other than the control configuration by the control unit as the control unit are the same as those in the above embodiment, so only the different configuration is used. explain.
As shown in FIG. 18, when the supply of the grain to the supply hopper 25 is started and the moisture measurement process is started, the transverse feed screw is started to start sampling of the grain, and each grain sample is taken. Moisture measurement is started to measure the moisture content while taking in and crushing the grain with a roller (steps 51 and 52), and the time for executing the measurement process after starting the moisture measurement is set time (Tw) as the set measurement time When the time has passed, the moisture measurement is terminated, and the operation of the lateral feed screw is stopped to stop the sampling (steps 53 and 54). And as shown in FIG. 19, the said control means changes in the state which makes the said measurement time Tw longer when the fluidity is higher than when the fluidity is lower based on the detection information of the fluidity measurement means. It is configured as follows.
[0063]
(3) In the above embodiment, as an example of a configuration in which the set period Ts1 for sample collection in the sample collection device 39 is shorter when the grain fluidity is higher than when the grain fluidity is low, Based on the correlation indicating a linear change, the setting cycle Ts1 is continuously changed. However, the present invention is not limited to such a configuration. For example, as shown in FIG. The setting cycle Ts1 may be changed stepwise, and at this time, it may be changed in three or more steps, or may be changed in two steps of large and small.
Similarly, when changing the set number of samples for moisture measurement when the grain fluidity is higher than when the grain fluidity is lower than when the grain fluidity is low, the change in the fluidity is linear. Instead of a configuration in which the set number M is continuously changed based on the correlation shown, a configuration in which the set number M is changed stepwise in response to a change in fluidity is possible. It is also possible to change it in two stages of large and small.
[0064]
(4) In the above embodiment, based on the detection information of the moisture measuring means for measuring the moisture content of the cereal, the measured fluidity is corrected to be lower as the moisture content is higher. It is good also as a structure which does not perform correction | amendment by a water | moisture content.
[0065]
(5) In the embodiment described above, the storage time from when the fluidity measuring unit starts storing grains to the weighing grain storage space in the batch type weighing unit until the grains of the set target weight are stored. Although it was set as the structure measured as the fluidity | liquidity of a grain, as said fluidity | liquidity measurement means, you may implement with various forms like the following (f)-(li) not only in such a structure, In short, any configuration may be used as long as it measures the fluidity of grains.
(F) A configuration in which the discharge time until the discharge of the grain from the storage space in the first discharge process after the start of weighing is measured as the fluidity of the grain.
(G) A configuration in which the elapsed time for performing a series of operations from the start of supplying grains to the storage space in the weighing hopper until the completion of the discharging operation is measured as the fluidity of the grains.
(H) A configuration in which the storage time, the discharge time, or the average value of the elapsed time for performing a series of operations as described above is measured as the fluidity of the grain.
(I) A configuration in which the magnitude of the load current in the drive motor when the grain is transported in the grain conveying device in the cargo receiving unit, for example, the first lifting conveyor 5, is measured as the fluidity of the grain.
(N) The size of the total weight Wt of the grain that has been weighed during the time when the property measuring means executes the measurement processing of the set number of samples or the time when the property is measured over the set time. Based on the configuration to measure the fluidity of grain.
In this configuration, the set number and set time may be changed according to the fluidity of the grain.
For example, as shown in FIG. 21, as a process for measuring moisture as a property, the supply of grain is started and moisture measurement is started (steps 61 and 62), and the number N of samples whose moisture has been measured is initially set in advance. When the set number M1 is reached, if the total weight Wt of the grains that have been weighed up to that time is smaller than the preset set weight Ws, the fluidity of the grains is greater than a predetermined value. If the total weight Wt of the grain is larger than the set weight Ws, it is judged that the fluidity of the grain is higher than a predetermined value. Then, when the additional number M2 to be additionally measured for moisture is set and the number N of samples whose moisture has been measured becomes the number obtained by adding the additional number M2 to the number M1, the moisture measurement is continued until the number reaches that number. Stop the measurement process It may be a structure that (step 65, 66, 67). In this case, the set number of samples for property measurement is switched to two levels, high and low.
[0066]
(5) In the above-described embodiment, the sample collecting means has exemplified that the sample is collected for measuring the yield of the grain as an example of the grain property. However, the property is not limited to the yield. It can be used for measuring various properties such as appearance quality, mixing ratio of waste grains, internal quality such as grain taste, and moisture content.
[0067]
(6) In the said embodiment, although what measured the moisture content of a grain was illustrated as said property measurement means, as a property, it is not restricted to a moisture content, For example, the external appearance quality of a grain, the mixing rate of a waste grain, a grain It can be used to measure the internal quality such as the taste of food and various properties such as the yield.
