As shown in FIG. 2 and FIG.
A sample grain (for example, about 500 g of paddy rice) for each farmer is set in a sample bucket 2a (10 pieces are provided in the embodiment) in the sample setting section 2 provided outside the area a. It is assumed that the sample paddy rice is appropriately dried in a predetermined drying facility (not shown). When a button (not shown) of the operation panel 63 or the sample setting section 2 is pressed, a shutter (not shown) is opened, and the sample is supplied to the sample supply port 3 via a rotating conveyor or the like.

In the main body case 1a, a supply skip 4, a first grain sorter 5, a treated grain skip 6, and a second
Working units such as a grain sorter 7, a discharge skip 8, a first weighing machine 9, a second weighing machine 10, a hulling machine 11 and the like are arranged, and as described later, sorted, collected, and weighed grains, Bagging device 3 from discharge hopper 30 shown in FIG.
The granules are transferred to the sample No. 2 and are discharged by being packed in a bag made of synthetic resin or the like for each sample number and for each selected sorting grade.

Next, the configuration of the main part of the assay device 1 will be described with reference to FIG. 1 and FIGS. The paddy rice of the sample supplied from the sample supply port 3 is once received by the paddy hopper 12 arranged on the left side in the main body case 1a, and the on-off valve 13 with the electromagnetic solenoid in the paddy hopper 12 is opened and the paddy rice is placed below the paddy rice. It is received by the hopper 9a of the first weighing device 9 arranged, and the first weighing device 9 of an electronic type or the like is used.
Is configured to measure the weight. The configuration of the second measuring device 10 described later is the same.

The opening / closing valve 14 with the electromagnetic solenoid provided at the discharge port of the hopper 9a is opened and moved to the bucket 15 stopped at the lowered position in the supply skip 4. The supply skip 4 is a drive wheel 4 such as a sprocket mounted on an output shaft of a drive motor 16 having a speed reduction mechanism disposed at the upper end.
a, a lower driven wheel 4b, and a bucket 15 connected to an endless belt such as a chain 4c wound around these wheels.
An opening / closing shutter (not shown) provided at a lower end discharge opening of the bucket 15 is spring-biased in a closing direction, and an operation lever (not shown) provided at a predetermined height position (a position at which the opening / closing shutter is opened). , And the opening / closing shutter is opened against the spring force. Note that the processing grain bucket 43 in the processing grain skip 6 to be described later and the discharge bucket 47 in the discharge skip 8 are also the bucket 1.
5, the detailed description is omitted.

The measured paddy is supplied from the bucket 15 stopped at a predetermined halfway position of the supply skip 4 to a receiving hopper 11a of a rice huller 11 disposed on the left in the main body case 1a, Brown rice receiving hopper 1 for brown rice after hulling
7, while the chaff is discharged to the chaff box 18 via a cyclone or the like. By driving the supply skip 4, the empty bucket 15 is lowered to the position where the grains are discharged from the brown rice receiving hopper 17 and stopped, and the open / close valve 19 with an electromagnetic solenoid provided at the discharge port of the brown rice receiving hopper 17 is opened. The empty bucket 15 is again thrown into the empty bucket 15 and rises to the throwing section 20 for the first grain sorter 5, and the slanted throw is made from the throwing section 20 to the supply hopper section 21 in the first grain sorter 5. A gutter 22 is arranged.

The first grain sorter 5 and the second grain sorter 7 are arranged side by side in a front view in the main body case 1a. Sorting machine 5
A hollow rotary sorting cylinder 24 having a sorting net 27a stretched in an octagonal cross section in front view and a hollow rotary sorting cylinder 25 having a sorting net 27b stretched in an octagonal cross section in front view in the second grain sorter 7. Are drive motors 26a, 26 which can rotate forward and reverse respectively.
b is driven to rotate. The roughness of the sorting net 27a stretched on the peripheral surface of the first rotary sorting cylinder 24 is such that sieving (grain such as brown rice having a large grain size that has been finely selected) cannot pass therethrough, and the grain size is larger than the sizing. A small screen (processed grain) is set to such an extent that it can pass through, and the sorting net 2 is stretched on the peripheral surface of the second rotary sorting cylinder 25.
The roughness of 7b is such that, among the treated grains, litter grains such as broken rice can pass, but immature rice (middle grains) such as blue rice, which has a larger particle size than the litter grains and a smaller grain size than the sized grains, can pass. It is set to be disabled. The sorting nets 27a and 27b may be perforated plates having a large number of holes corresponding to a predetermined particle size.

As shown in FIG. 6, the rotary sorting cylinder 24 (25) is disposed so as to be inclined downward by an appropriate angle θ toward the small room 35 defined on one side of the sealed case 23. First rotary sorting cylinder 24 and second rotary sorting cylinder 2
When 5 is rotated forward (rotated counterclockwise in FIG. 4), small grains leak through each sorting net. And, between the side plates at one end of the rotary sorting cylinder 24 (25),
While forming a hollow passage having an octagonal shape in front view facing the small room 35, one end of a laterally open intake gutter 41 disposed on the inner peripheral surface of the rotary sorting cylinder 24 (25) is connected to the hollow passage. And a discharge hole formed outside the hollow passage communicates with the inside of the small chamber 35.
4 (25), the sized particles remaining in the inner diameter part are
When 4 (25) is reversely rotated, it is discharged from the small room 35.

Therefore, the sizing in the first rotary sorting cylinder 24 is introduced into a sizing hopper 33 having an opening / closing valve 33a at the lower end, and is collected. Sorting net 2 of first rotary sorting cylinder 24
Processed particles having a smaller particle size than the sized particles leaked from 7a are introduced from a large room of the sealed case 23 into a processed particle hopper 34 having an open / close valve 34a at the lower end, and are collected. On the other hand,
The intermediate grains remaining in the inner diameter portion of the second rotary sorting cylinder 25 are introduced into an intermediate grain hopper 36 having a lower end with an on-off valve 36a, and are collected. Similarly, small dust particles leaking from the sorting net 27b of the second rotary sorting cylinder 25 are introduced from a large room of the sealed case 23 into a waste hopper 37 having an open / close valve 37a at the lower end. Grained. Each of the on-off valves 33a, 34a, 36a, 37a is urged in the closing direction by an unillustrated urging spring, and is opened by electromagnetic solenoids 38a, 38b, 38c, 38d against this urging force. It is configured as follows.

Processed grains having a smaller particle size than the sized granules leaked from the sorting net 27a of the first rotary sorting cylinder 24 are collected in a treated grain hopper 34 and stopped at a lower position in the treated grain skip 6. The processed grain bucket 43 is received by the grain bucket 43, and the processed grain bucket 43 is raised to a position of the treated grain supply hopper 44 in the second grain sorter 7, and the treated grains are thrown into the treated grain supply hopper 44. The small-sized dust particles leaking from the sorting net 27b of the second rotating sorting cylinder 25 rotating forward are received by the above-mentioned dust grain hopper 37, collected, and then passed through the second rotating sorting cylinder 25. By rotating in the reverse direction, the intermediate grains having a smaller diameter than the sized grains and a larger diameter than the waste grains become the intermediate grain hopper 3.
It is introduced in No. 6 and collected.

In this way, the particles can be sorted so as to be classified according to the particle size. The sized particles accumulated in the sized hopper 33, the intermediate particles accumulated in the intermediate particle hopper 36, and the litter particles accumulated in the litter hopper 37 are weighed by the weighing hopper 10a in the second measuring device 10 for each sorting grade. After being discharged to the discharge bucket 8, the on-off valve 46 with the electromagnetic solenoid is opened, and the discharge bucket 47 is moved to the discharge bucket 47 stopped at the lower position in the discharge skip 8. The granules are released and sent to the bagging device 32 via the discharge gutter 31. This operation is sequentially repeated for the sized, intermediate, and waste particles for each sample. From the discharge unit 48 of the bag packing device 32, the sized, intermediate, and waste particles for one sample are sealed in a bag 49 for each sample. It is released.

The block diagram shown in FIG. 7 is an electronic controller 60 such as a computer as a control means for automatically controlling the above-mentioned operations of sorting, weighing and bagging.
The controller 60 includes a CPU 61 as an arithmetic means for executing control and calculations to be described later, a ROM (read only memory) 65 storing a control program, and input values such as set values and various data such as detected values (measured values). A data memory 63 such as a RAM, which can be read and written at any time, as a storage means for storing, a keyboard 64a and a touch panel type liquid crystal display unit 6
Operation panel 64 including 4b, printer 62, alarm 67
7, and although not shown in FIG. 7, the bag filling device 32, the huller 11, the first grain sorter 5, the second grain sorter 7, the first scale 9, the second scale 10, Supply skip 4,
Processing grain skip 6, discharge skip 8, each hopper 33,
Electromagnetic solenoids 38a, 38b, 38c, 38d for operating the on-off valves in 34, 36, 37,
4, 19, and 46 electromagnetic solenoids for operation are connected.

As described above, the controller 60 separates the grain from the hulling operation for each sample by sorting the grains for each sample, and separates the classified sized, intermediate, and waste particles separately. The operation of bagging and the printing of the test result are automatically executed. An example of the operation of the control and operation by the controller 60 will be described in detail. The screen of the touch panel 64b (shown in an enlarged view in FIG. 8) provided on the operation panel 64 in FIG. Displayed after the operation of a “preparation screen” (not shown) or a “confirmation screen” (not shown) of the roughness of the sorting net in the first grain sorting machine 5 and the second grain sorting machine 7. Screen ", a timer displays the current date, the first number of the sample (consignment), and the like. Here, when it is desired to change the inspection date or the test object, the user touches the “screen selection” button in FIG. 8 to display the “screen selection screen” shown in FIG. Touching the button of "screen" switches to the screen of FIG. Therefore, when it is desired to change the inspection date in FIG. 10, a numerical value is input using a keyboard (such as a numeric keypad). By touching the button of “switching of processing object”, it is possible to switch between two types of “rice processing mode” and “wheat processing mode”.

Next, when changing the setting values of the huller 11, etc., the "screen selection" button is touched to display the "screen selection screen" shown in FIG. Here, the user can touch the button portion of the setting screen in each component to change the set value. Touching the button portion of the “hulling-related setting screen” in FIG. 9 switches to the “hulling-related setting screen” shown in FIG. 11, so that the set value can be switched by pressing the ten keys.

In the "input screen" shown in FIG. 8, after confirming that the respective numbers are correct and pressing an execution button (not shown) on the operation panel 64, the supply of the paddy rice and the The data of the sample weight measured by the first measuring device 9 and the data of the sized, intermediate, and waste particles measured by the second measuring device 10 are executed until sorting, weighing, and bagging are performed. , Are stored in the data memory 63 collectively for each sample number (inspection number). And
In the calculation unit (CPU 61), the sizing rate (ratio%) with respect to the sample weight, the sizing rate (ratio%) of the intermediate grains, the swarf rate (ratio%), and the weight sum of the sizing and swarf grains similarly (Ratio%) is calculated, and this is also stored in the data memory 63 collectively for each sample number (inspection number).

FIG. 12 shows the sample weight for each sample number (inspection number), the sizing, and the weight of each piece (each unit g) displayed when the "processing data transfer screen" in FIG. 9 is activated. This is a graph display. FIG.
3 is a graph showing the rate of sizing for each sample number (inspection number) and the rate of the sum of the weight of sizing and waste (with respect to the sample weight).

As described above, when the weight and the commission are displayed in a graph for each sample number, the operator can see at a glance whether the test result is right or wrong, and can easily compare the normal test with the error. For example, in the weight display graph of FIG. 12, in the sample number 15, since the sample weight and the sizing weight are extremely small as compared with other samples, the paddy rice is clogged at the place of the paddy hopper 12 and the whole amount is not released. Is determined. In addition, since the sample weight is larger than the other samples at the positions of the sample numbers 16 to 18, the sample number 16 to 18 may be mixed with the sample of the sample number 15, Therefore, at least the sample numbers 15 to 18 are erroneous and need to be re-tested. Further, in sample No. 20, since the weight of the sized granules is extremely low as compared with those of the other samples, the granules are formed between the supply skip 4 and the sized hopper 33 of the first grain sorter 5. It may be stuck and should also be considered an error.

Further, the sample number 20 in FIG.
It can be seen that the percentage of sizing and the total percentage of sizing and waste particles are extremely low as compared with other samples. In addition, it can be seen that the sizing rate and the sum of the sizing and waste particles in the sample numbers 21 to 24 are higher than those of the other samples. Therefore, from the graph of the commission, the test should be redone even after the sample number 20.

In the controller 60, in order to easily leave such an error to the operator, the standard value of the sample weight, the rate (ratio) of sizing, and the rate (sum of the sizing and waste particles) are determined in advance. The standard value of the ratio (predetermined value determined for each region and rice variety from the accumulated data in the past) is stored in the ROM 65 or a data memory 6 such as a rewritable RAM or a non-volatile memory which is not erased even when the power is turned off.
3 is compared with the result measured and calculated for each sample, and when the value in a specific sample is greatly deviated from a predetermined value or a predetermined ratio, the alarm device 67 is activated, The worker is informed that the test is not successful. Here, the CPU 61 functions as a calculating means and a comparing means for executing the above-described calculating and comparing operations.

When an error occurs or an alarm is activated, the date and time are stored in a nonvolatile memory as a history, and can be called up and displayed on the touch panel 64a as necessary. Keep it. In this history memory area, a plurality of cases (for example, 20 cases) from the latest date and time of occurrence can be stored, and when the number of cases exceeds this number, the oldest one is deleted. With such a configuration, there is an effect that information to be referred to at the time of later inspection and repair can be quickly obtained.

Further, on the switching screen of the touch panel 64b, as shown in FIG. 1, a graphic of each component of the test apparatus 1 and a work flow are displayed, and each component on the screen is touched. By doing so, the controller 60 is provided with a program that performs control so as to switch to a screen that displays information on the components. For example, when the position of the huller 11 is touched on the switching screen, the set value of the huller is displayed, and the work status of the huller, for example, which sample number is being processed is displayed. It is configured to switch to the screen to be displayed. Further, the setting value may be configured to be changeable on a screen on which this information is displayed. As a result, there is an effect that the operability of the testing device is further simplified, as is the case with recent operations using icons on the screen of a personal computer.

The paddy hopper 12, the hopper 9a,
Brown rice receiving hopper 17, sizing hopper 33, treated hopper 34, intermediate hopper 36, waste hopper 37,
Other hoppers, buckets 15, 43, 47, etc. are provided with sensors for detecting whether or not the particles are clogged in a bridge shape. When the clogging is detected, a vibrating device (shown in FIG. ) Can prevent the particles from remaining in the hopper or the bucket in a bridge shape.

The sample number and / or the name of the sample submitter, the sample weight, the size of the sized product, the weight of each of the intermediate particles and the waste particles, the percentage of the sized product relative to the sample weight (%), the percentage of the intermediate product (%), and the same The test paper on which the test results (data) such as the percentage of waste particles (%) are printed by the printer unit attached to the bag packing device 32 is enclosed in each bag 49, or the test paper is stuck on the bag 49. Alternatively, the determination result is printed directly on the surface of the bag 49. On the other hand, a paper or the like on which a test result of a predetermined format is printed is also output from a printer 62 provided on a front surface of the main body case 1a of the test device 1 or the like.

The hulling machine 11 is configured to measure the time required for hulling for each sample, and when it is determined that the required time is too long or too short in a normal case, an alarm is issued and a worker is notified. In addition, it is preferable to automatically control the opening degree of the supply valve in the huller 11 in addition to the above. In addition, in the bag filling device 32, for one sample, the lower end of the cylindrical synthetic resin bag is heat-sealed, the sizing portion is put therein, and then the upper part is heat-sealed. Put the intermediate grain part and heat-seal it, and then put the waste particles in the upper part and heat-seal it to make a continuous bag that is divided for each grain part,
If the bag is configured to be separated for each sample, the bag can be easily distinguished from other samples. In addition, by interlocking the operation of the conveyor for transporting the bagged items to the outside, breakage from the heat-sealed portion of the bags and the like can be prevented.
