Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a quality measuring device for sample grains.

[0002]

[Problems to be solved by conventional techniques and devices]

 It is known that the grain is packed into a sample through a test drying of the consigned grain and a voluntary test, and it is also known that the grade of the sample-packed grain is graded by visual determination (for example, Jitsukaihei 2-129847). Bulletin). However, since the conventional method relies on visual observation, the measurement results vary. This device is intended to eliminate such drawbacks.

[0003]

[Means for Solving the Problems]

 For this reason, the present invention is provided with a sample pack mechanism 7 for receiving a part of the grain to be received, passing through a test dryer 5 and a voluntary inspection device 6 and sorting the sample grain into at least brown rice and scrap rice and bagging them. The sample grain quality measuring device is provided with a quality detecting device 17 for determining the quality of the brown rice contained in the bag, in the middle of the transportation path for feeding the continuous sample-containing bags to the storage location.

[0004]

[Function and effect of the device]

 It has a sample pack mechanism that receives a part of the received grain, passes through a test dryer and a voluntary verification device, and sorts the sample grain into at least brown rice and scrap rice and bags it. Since a quality detection device that determines the quality of the brown rice contained in the bag is installed in the middle of the transportation route for feeding to the location, grain quality can be detected automatically, so there is no need to rely on visual inspection as in the past. It leads to improvement of accuracy. However, since the quality of the grain after being packed through the voluntary verification device is detected, it is clear that the grain is plain rice that does not contain waste rice, which is convenient for determining the quality of regular brown rice. Is.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a cargo receiving unit, which is configured such that the received grain is conveyed to a primary storage tank (not shown) via an elevator 2 and a cargo receiving and measuring device 3. The cargo receiving and weighing device 3 has a sampling mechanism, and a part of the grain for each cargo receiving and weighing is taken out to the test dryer 5. This test dryer 5 and the subsequent voluntary verification device 6 have a known structure. After the sample grain is dried to a predetermined moisture value by the test dryer 5, it is transferred to the voluntary verification device 6 for removal and selection. It is sorted into regular brown rice and scrap rice. The voluntary inspection device 6 has a weighing mechanism and can detect the weight of each of the input paddy, the unpolished rice, and the scrap rice. The grain in the primary storage tank is subjected to a dry preparation process.

[0006] As described above, the dry sample paddy that is put into the voluntary verification device 6 is separated into unpolished rice (dotted line in the figure) and scrap rice (dotted line in the figure) and taken out, and the paddy sample remains as the dried sample paddy. Along with (solid line in the figure), the sample pack mechanism 7 is guided. The sample pack mechanism 7 is composed of a sample supply hopper 8, a pair of transparent film F feeding parts 9, a heat seal part 10 and the like, and partitions or seals the film F to form a plurality of accommodating parts continuously, and inside each of them, a loading port. The structure is such that the paddy, scrap rice, and brown rice are transferred in this order to the supply hopper 8 and subjected to bagging processing. It should be noted that the sample pack mechanism 7 receives the consignee code, product type, acceptance date, voluntary verification result, etc. from the consignor (not shown) via the central controller 11 and the printer (Fig. It is configured to be output to the data slip from (not shown). This data slip D is output together with the barcode for the consignee, and is enclosed in a predetermined space provided between the scrap rice sample and the brown rice sample.

Reference numeral 12 denotes a chute for guiding the sample storage bag to be fed out, 13 denotes a guide roller, and the guide roller 13 is constituted from the chute 12 as a conveyance path, and a quality measuring device 14 is provided. Grain quality judgment refers to the judgment of the foreign matter mixture ratio, the cracking condition of the brown rice, and the coloring condition of the brown rice. The quality judgment device 14 uses the pressure rolls 15 and 15 and the receiving paper preprinted on the data slip D. It is composed of the above-mentioned bar code reader 16 for human discrimination and an optical quality detector 17.

The optical quality detector 17 employs a line sensor camera, which allows the whole brown rice pack portion which is stretched in a thin layer to be observed, and mainly detects the mixing ratio of the colored rice depending on the degree of coloring. It has a function. This detection result is output to the controller 11 and stored together with the above-mentioned voluntary verification data, while it is used as calculation data for the amount conversion to the brought-in farm.

Below the guide roller 12, a sample pack storage box 18 is seen, and the sample pack storage box 18 can be appropriately reciprocally moved back and forth to store a continuous sample pack in a folded shape. The operation of the above example will be described. The sample grain (paddy) from the load receiving and weighing device 3 is transferred to the test dryer 4. Here, it is dried for a predetermined period of time at a predetermined drying loss rate and dried to a finished moisture value. Subsequently, the sampled paddy is sent to the voluntary inspection device 6, and a part of the inside is left inside the device 6. In this process, test hulls and graders are used for sorting, and it is divided into regular rice and scrap rice, and the total weight and these weights are sent to the controller 11 for storage and the yield rate is calculated together. ..

The paddy waiting in the voluntary verification device 6 and the sorted and weighed scrap rice and smoothed rice are sent to the sample pack mechanism 7 in this order by an air transfer mechanism (not shown). The film that is successively fed out is formed into a bag shape, and the paddy, waste rice, data slips, and plain brown rice are packed into a partitioned space as a cargo port. Here, the film is not cut, and the same processing is performed for another cargo port.

When the controller 11 receives the detection signal from the bar code reader 16 among the sample packs on the transport path, the sample pack immediately after that, that is, the state of brown rice is detected by the line sensor camera as the quality detector 17. To be done. The camera divides the pixel into a plurality of pixels and determines the quality by a method of determining whether or not each pixel is normal brown rice and a method of estimating the degree of coloring from the total number ratio of the brown rice estimated pixel and the non-brown rice estimated pixel.

In the above-described quality detection, the sample is pressed by the pressing rolls 15 and 15 to form a thin layer, so that the detection accuracy is not deteriorated without being localized.
