2. Description of the Related Art The above-mentioned quality measuring device is disclosed, for example, in Japanese Patent Laid-Open No.
As disclosed in Japanese Unexamined Patent Publication No. 300350, the grain processing equipment is provided and used. In other words, the grain processing equipment, the grain before receiving into the receiving unit, or
The grain to be inspected, which is collected from the grain before being weighed after being received by the receiving unit, is supplied to the quality measuring device in a state where the drying process is not performed, and the quality measuring device discriminates for sorting. It is designed to detect information, whereby the grain to be inspected collected at the time of being weighed after being received by the receiving part is supplied to the quality measuring device,
Compared to the one that detects the discrimination information for sorting, a wait time is avoided until the weighed grain is transferred to the processing in the drying unit, and further, the collected inspection grain is dried. Since the drying process takes a longer time than the one that is supplied to the quality measuring device after
By avoiding waiting more time, the work efficiency of grain processing was improved as much as possible.

Further, in the construction of a quality measuring device, conventionally, the grain to be inspected supplied to the hopper for grain supply is directly supplied to the depulling section to be depulled, and the grain after the depulding treatment is carried out. Quantitatively, in the quality measurement unit, for the quantitatively measured grains, the water content by a taste meter,
The taste and the like were measured, and the quality of grain was measured by determining the quality of appearance such as normal grains or defective grains by an appearance quality meter.

By the way, the grain brought into the grain processing equipment is obtained by cutting the grain culms in the field with a combine or the like, and transporting the harvested grain culms by a truck or the like. May contain straw chips, grains with branching, etc., and when the grain to be inspected collected from such grains is supplied to the quality measuring device, clogging of straw chips, etc. occurs in the removing section, As a result, the operation of the removing section stops, or the removing operation in the removing section is not performed properly and the removal rate decreases, so that the quality measurement section should perform quality measurement properly. May not be possible. In such a case, it is necessary to stop the operation of the quality measuring device to remove the clogging, and until the clogging is cleared, measure the quality of the grain received by the grain processing equipment and sort it. However, there is a problem in that the processing in the grain processing equipment cannot be smoothly executed based on the classification information for sorting. In particular, the harvesting and harvesting work will be concentrated for a period of time, and the delivery to the grain processing equipment will also be concentrated, so if troubles occur with the quality measuring device at such times, it will be difficult to process many brought-in grains. It will not be possible to put it in the box and it will cause a great deal of trouble to the supplier.

The present invention has been made in view of the above circumstances. A first object of the present invention is to smoothly perform a quality measuring operation on a grain to be inspected, which contains straw chips, etc., without trouble as much as possible. The second object is to provide a quality measuring device capable of performing the above, and a second object is to obtain the discrimination information for sorting by measuring the quality of the grains sequentially received by the grain processing equipment by the quality measuring device. In addition, it is necessary to detect the above discrimination information as much as possible with regard to grains to be inspected that include straw waste, etc., and to smoothly perform the processing in the grain processing equipment based on the discrimination information for sorting. It is in.

[0006]

According to a first aspect of the present invention, a grain quality measuring device is provided with a hopper to which a grain to be inspected is supplied, and a coarse selection section for selecting a grain supplied from the hopper. A depulling unit that depries the grain supplied from the rough selection unit, and a preset amount of grain necessary for quality measurement by weighing on the grain supplied from the depulping unit and separating from other grains And a quality measuring unit for measuring the quality of the set amount of grains separated by the quantitative measuring unit. In other words, the grain to be inspected supplied from the outside to the hopper is supplied from the hopper to the coarse selection unit, the scraping action of the coarse selection unit removes the straw debris, and the grain from which the straw debris has been removed is removed by the desorption unit. Is fed to the grain and is subjected to degumming, and the dequantified grain is weighed by the quantitative measuring unit to separate the set amount of grain required for quality measurement from other grains, and the separated set amount. The quality of the grain is measured by the quality measuring unit. Further, according to claim 1, the inspection target is provided on the hopper.
Supply detecting means for detecting whether or not the grain has been supplied,
And a control means for controlling the quality measurement operation of the grain,
The control means feeds the feed detection means to the front of the hopper.
As soon as it is detected that the grain has been supplied,

It is configured to control each of the driving operations.

Therefore, even when the grain to be inspected supplied to the quality measuring device contains straw debris and the like, the grain from which the debris and the like have been properly removed by the sorting operation of the rough selection section is removed in the depulling section. Since it will be processed, as in the past,
If the grain to be inspected containing straw waste etc. is directly supplied to the dewetting section and is subjected to dewetting treatment, the straw debris etc. becomes clogged in the dewetting section, and as a result, the operation of the dewetting section stops. Or the removal operation in the removal section may not be performed properly and the removal rate may decrease, making it impossible to properly perform quality measurement in the quality measurement section. Therefore, it has become possible to obtain a quality measuring device capable of avoiding such a problem and performing a measurement operation with as little trouble as possible. Also, as the grain to be inspected is supplied to the hopper,
Then, the supplied grain is supplied from the hopper to the rough selection section.

Wear.

According to a second aspect of the present invention, in the first aspect, the rough selecting section has a cylindrical body having an outer peripheral wall formed with a large number of passage holes for allowing grains to pass, and the cylindrical axis of the cylindrical body is arranged in the horizontal direction. It is provided rotatably around the cylinder axis in a state of being directed, and is configured to pass the grain to be inspected from the upper side to the lower side of the cylindrical body to perform a sorting action. In other words, the cylindrical body provided with the outer peripheral wall in which a large number of passage holes for allowing the grain to pass is driven and rotated around the cylinder axis centering in the horizontal direction,
When the grain to be inspected is supplied to the upper side of the cylindrical body, the grain passes through a large number of passage holes formed in the outer peripheral wall of the cylindrical body and passes from the upper side to the lower side of the cylindrical body. It is skipped in the rotating direction of the cylinder, and is selected by this. Therefore, when the rough selection unit is composed of, for example, an oscillating type rough selecting machine that oscillates the sorting plate on which the objects to be sorted are oscillated, the oscillating operation is slow, and thus the sorting operation is slow. I feel bad
In addition, the vibration associated with the rocking motion is large, and compared to the large-sized device due to the rocking mechanism and the sorting plate, the sharpness of the sorting can be improved by the rotating motion, and the vibration due to the rotating motion. Has a merit that it is possible to make a coarse selection section of small size, and thus the preferred means of claim 1 can be obtained.

According to a third aspect of the present invention, there is provided a feeder according to the first or second aspect, which conveys, from the hopper, a grain to be inspected to the coarse selection unit by a set amount per unit time. Therefore, since the grain to be inspected is conveyed by the feeder from the hopper to the coarse selection unit by the set amount per unit time, if a large amount of grain is supplied from the hopper to the coarse selection unit at a time without the feeder, Grains may be removed together with the straw scraps that are selected and removed in the rough selection section, and grain loss may occur. Compared to the possibility that the performance (plucking rate) may decrease, such a problem can be avoided, and the preferred means of claim 1 or 2 can be obtained.

According to a fourth aspect of the present invention, in the third aspect, the feeder is a rotary feeder.
Therefore, for example, in a vibrating feeder that vibrates and conveys a vibrating plate on which grain is placed, the vibration noise accompanying the swinging operation is large, and unconveyed grain may remain in a corner or the like with respect to the center of the vibrating plate. In contrast to the above, since the roll-shaped conveying member is rotated, the operation noise can be reduced and the unconveyed grain can be conveyed in a state where it does not remain. Therefore, the preferable means of claim 3 can be obtained. .

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the take-off section is configured to be an impact-rubbing type. Therefore, since the grain will be subjected to the depuffing treatment by impact, when the depuffing part is constituted by, for example, a roll type hulling machine, it is possible to satisfactorily remove the grain in the unhulled state that has not been dried. Compared with being unprocessable, it is possible to remove the unwheated grain in a good manner.
The preferred means of any one of claims 1 to 4 is obtained.

According to a sixth aspect, in any one of the first to fifth aspects, there is provided a supply port for directly supplying the grain to be inspected to the rough selection section or the deplucking section.
Therefore, when the grain to be inspected supplied to the hopper is insufficient in the set amount required for quality measurement, additional grain is directly supplied from the above-mentioned supply port to the rough selection section or the depulling section and the quality is improved. The set amount necessary for measurement can be set and the quality measurement can be smoothly performed. Especially when the grains to be inspected are sequentially supplied to the hopper, when the grains in the hopper are sent to the rough selection section, Since the grain of the above is supplied to the hopper and the additional grain cannot be supplied from the hopper, the quality measurement cannot be performed without the supply port for the above additional input. Therefore, the preferred means of any one of claims 1 to 5 can be obtained.

[0013]

According to claim 7, any of the preceding claims
In paragraph 1 , the quantitative weighing unit is provided with quantitative detection means for detecting whether or not the set amount of grains has been separated, and the control means supplies the grain to the hopper by the supply detection means. If it is not detected that the set amount of grains has been separated by the quantitative detection means even after the set time has elapsed after it is detected that the supply amount of the inspection target grains is insufficient. It is configured to operate the notification means for notifying that the user is present. That is, during the set time, after the grain to be inspected is supplied to the hopper, it is processed in the rough selection section and the depulling section and sent to the quantitative measuring section, and the quantitative measuring section separates the set amount of grain. It is set to the time required to add the margin time. Therefore, it is automatically determined that the supply amount of the inspection target grains supplied to the hopper is insufficient with respect to the set amount necessary for quality measurement, and the insufficient supply amount of the grains is notified, and based on the notification, for example, Since additional grains can be supplied from the supply port to the roughing section and the depulling section, the measurement operation should be started when the grain supply amount is insufficient, and the quality measurement operation may not be performed properly. It is possible to appropriately avoid such a situation, so that the preferred means of any one of claims 1 to 6 can be obtained.

According to claim 8, receiving the grain receiving portion, and a load receiving portion that performs load receiving process of weighing the accepted crop for consignment treated grain, based on the determination information for sorting sorting a drying section in a state the drying process, a dry cereal processing equipment that includes a reservoir for storing grain, quality measurement device grain according to any one of claims 1-7 Is provided, the grain before receiving into the receiving unit, or the grain to be inspected collected from the grain before receiving the weighing after receiving into the receiving unit, the quality measurement without performing a drying process It is configured such that the sorting information is supplied to an apparatus and the sorting information is detected by the quality measuring apparatus. Therefore, the grain to be inspected collected from the grain before being received in the receiving part or before being weighed after being received in the receiving part is dried while the receiving process is being performed in the receiving part. Since the quality information is measured without processing and the discrimination information for sorting is detected, it is possible to minimize the waiting time for detection of discrimination information. It contains a lot of grains with branch branches,
Alternatively, even if a large amount of dust is attached after cutting, the quality measuring device removes straw debris properly and performs measurement with the trouble such as clogging as small as possible to obtain the discrimination information for sorting. Therefore, the processing in the grain processing equipment can be smoothly executed based on the discrimination information for sorting. In particular, even when deliveries to grain processing equipment are concentrated during the harvesting season, it is possible to measure sorting information for many brought-in grains and input them into the processing equipment in sequence, so problems with quality measurement equipment As a result, a grain processing facility can be obtained that can avoid the inconvenience that the processing is interrupted and the supplier is greatly inconvenienced.

When the hulling machine 53 is in operation when the loading sensor 51a is turned on, and when the start time T1 has elapsed after the operation is started, it is determined whether hulling is possible. The condition under which hulling is possible is a state in which the transport lift of the transport unit HU is stopped and an empty container stands by at a position that can accept brown rice carried in from the carry-in gutter 81.
When hulling is possible, the rotary feeder 56 and the rough selector 52 are activated, and it is determined whether or not the loading sensor 51a is turned off. After the closing sensor 51a is turned off, the sensor delay time T2 is further increased.
As (5 seconds) elapses, the rotary feeder 56
Then, the operation of the coarse selector 52 is stopped and the lift standby flag is turned on.

In the processing from the transportation by the transportation unit to the quantitative weighing (FIG. 11), when the lift standby flag is turned on, the rice huller waiting time T3 (15 seconds) is waited until the processing in the rice huller 53 is completed. Then, when the waiting time T3 for the huller has elapsed, it is determined whether the huller can be transported. The condition that the transportation is possible is when the quantitative sensor 68b is in the off state (the box 68a is empty). When it is determined that the transportation is possible, the transportation unit HU is operated, the lift standby flag is turned off, and the fixed quantity sensor flag is turned on.

Processing from quantitative measurement to taste measurement (Fig. 1
In 2), when the quantitative sensor flag is turned on, it is determined whether the quantitative sensor 68b is in the on state. Quantitative sensor 6
When 8b is in the off state, it is judged whether or not the set time has elapsed since the closing sensor 51a was turned on. Even if the set time has elapsed since the closing sensor 51a was turned on, the quantitative sensor When 68b is in the off state, it is determined that the input sample is insufficient, and "insufficient sample" is displayed on the screen of the touch panel 62 to notify. That is,
The touch panel 62 constitutes an informing unit for informing that the supply amount of the grain to be inspected is insufficient. When the operator additionally supplies the shortage amount from the supply port 54 by looking at this shortage display, if the hulling machine 53 has stopped operating,
With the manual switch provided on the touch panel 62, the huller 53
Will be started. The above set time depends on the hopper 51.
It is set to a time (for example, 90 seconds) obtained by adding a margin time to the time required for the paddy rice thrown into No. 2 to be supplied to the quantitative weighing unit 68 after undergoing rough selection, hulling, and the like. When the quantitative sensor 68b is turned on, it is determined whether or not the tasting meter 63 can perform measurement (a state in which the measurement of the sample previously put in has been completed). When it is determined that the measurement can be performed, the shutter 69 is opened and the sample is eaten by the taste meter 6
Send to 3. Then, when the quantitative sensor 68b is turned off, the shutter 69 is closed after the time T4 (4 seconds) has elapsed, and the taste measurement by the taste meter 63 is started. When the taste measurement is completed, the sample is discharged and the processing is completed.

In the stopping process of the huller machine 53 (FIG. 13), it is determined whether or not the huller machine 53 is in operation. When the huller machine 53 is in operation, the loading sensor 51a is turned off. If the rotary feeder 56 and the rough selector 52 are being activated, the stop timer is started. When the input sensor 51a does not turn on before the set time (60 seconds) of the stop timer elapses, it is determined that the sample paddy rice is not supplied, and the operation of the rice huller machine 53 is stopped, and the stop timer sets the set time ( If the closing sensor 51a is turned on before the elapse of 60 seconds, the process returns to the beginning.

The numbers attached to the time chart of FIG. 14 indicate the numbers of the producers corresponding to the order in which the sample paddy is placed. Even if the next producer's sample paddy is input while the measurement is being performed, those measuring procedures are properly managed.

From the above, the control unit 66 starts the grain quality measuring operation when the feeding sensor 51a detects that the grain is supplied to the hopper 51.
To control the supply operation from the hopper 51 to the coarse selector 52, the operation operation of the coarse selector 52, the operation operation of the removing unit 53, the operation operation of the quantitative measuring unit 68, and the operation operation of the quality measuring unit 63. In the case where it is configured, the quantitative sensor 68b does not detect that the set amount of grain has been separated even after the set time has elapsed after the input sensor 51a detects that the grain has been supplied to the hopper 51. In addition, the touch panel 62 is configured to perform an alarm operation of a shortage of the supply amount.

The measurement results such as taste and moisture information measured by the quality measuring device F1 are input to the data management device F2, and the data management device F2 uses the input information as identification information such as the identification number of the producer. It is managed in a state of being associated with, and is output to the control device SH as discrimination information for sorting. That is, in this grain processing facility, the inspection target grain collected from the grain received in the receiving section A is measured by the quality measuring device F1 and is sorted based on the discrimination information for sorting measured at the time of receiving the grain.

Such taste and moisture are measured with sample paddy, the quality of the grain is comprehensively evaluated and sorted based on the measurement result, and the subsequent processing such as the drying process is performed for each measurement state. Processing is performed under different conditions that are appropriate. In the figure, the fact that the grain flow after the drying process is branched into multiple does not mean that multiple dryers process them in parallel at the same time, but the grain flow in such a sorted state is It represents. It should be noted that, based on the shipping instruction information that is separately input, the silo 9 is provided so that grains of different qualities managed separately are shipped individually or in a state where they are mixed at a set mixing ratio. To a state in which the discharge state of grains is controlled, and the measurement information of a temperature sensor (not shown) or a moisture meter provided in the drying process or silo 9 is displayed on the monitor.
