Abstract

PURPOSE:To solve an inconvenience that the weight of every sample grain offered for voluntary examination is varied for every examination by arranging so that the weight of said sample grain obtained after it is completely dried by a dryer is always constant. CONSTITUTION:When grains are carried into an equipment where they are dried and the weight of the effective grains starts to be measured by a measur ing instrument 1A, sample grains as collected by a sample collector 2A during the measurement. The sample grains are transferred by a cyclone 3 and accom modated into a bucket 7 of a conveyor 6. The bucket 7 is transferred by the movement of the conveyor, so that the sample grains in the bucket 7 are thrown into a meter 8A. The initial moisture of the sample grains is measured by a moisture sensor 9A. The initial weight Wo of the sample grains corresponding to the measured value of the moisture (mo) is obtained. The conveyor 6 is again driven to send the sample grains in the bucket 7 to the meter 8A until the weight reaches Wo. Thereafter, the sample grains are thrown into a dryer box 11 which is sent into a drying chamber 13. After the sample grains are dried to have a predetermined weight W1, the grains are led into a distributor 15A.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used in a grain drying and preparation facility that receives grain from each producer, goes through the steps of drying, sorting, and storage, and then ships it. , the receipt is related to the improvement of a grain self-inspection system that tests the quality of grain from a sample of a portion of the grain.

(Prior art) Conventionally, in this type of system, when the receiver weighs the grain with a weighing machine, he or she takes a portion of the grain as a sample (for example, IKg) and dries it with a sample dryer. was. During drying in the dryer, when the moisture content of the sample reaches the finished moisture content, the sample is supplied to a self-testing device for self-testing.

As described above, conventionally, each sample supplied to the sample dryer is a quantitative amount, but since each sample has a different initial moisture content, each sample has a different weight when dried to a finished moisture content.

(Problem to be solved by the invention L2) Therefore, in the past, it has been difficult to carry out self-verification using a self-testing device, and to measure in advance i′ji,♀, , 41 meters were required to be installed in the I'-Il-, assay device, and the measured values varied depending on the sample.

The purpose of the present invention is to eliminate such inconveniences. (One stage of solving the problem of time Il!f!shi?) In order to achieve the above object, the present invention has the following features. The structure of the bar is as follows: [5] In other words, according to the present invention, a part of the grain is collected by the receiver →) A moisture meter is used to measure the initial moisture content of the grain, and a moisture meter is used to dry the grain. and an initial step of determining the initial weight of the sample to be dried in the sample dryer based on the measured moisture value so that the sample to be dried in the sample dryer has a constant finished weight. a weight calculation means, a sample supply means for supplying the sample to the sample dryer by the calculated initial weight of the sample; and a sample dryer for measuring the weight of the sample being dried in the sample dryer. , the 3tll constant value reaches 1-1. The sample dryer is equipped with a cutting sheath [discharge stage] for the first time when the sample is dried.

(Function) With the present invention configured as described above, one day before drying the sample in a 4-ton pull dryer, the moisture content is determined by a moisture meter to be x+l! Make a decision.

Based on the measured value, the initial weight calculation means drys the sample using a sample dryer. 1) Calculate the initial weight of the 2/pull during drying in the sur-pull dryer described above so that the finished weight of the sani-pull to be removed is always constant.

Then, when the initial weight of this sample is calculated, the sample supply means supplies the sample '#1) corresponding to the calculated initial type 1- to the sample dryer.

The weight of the sample that is being dried in the sample dryer is determined using a weighing scale. Then, when the measured value reaches the limit mentioned above, the sample is discharged from the sample dryer by the sample discharge means.

Therefore, the weight φ of the dried sample discharged from the sample dryer is always constant.

A switching valve 30B similar to the switching valve 3OA is also provided below the initial weighing scale 8A.

The sample dryer 10A is from the initial weighing scale 8A to jJI
The dried sample grains are received in a drying box 11, and the drying box 11 is carried into drying chambers 13 arranged vertically and horizontally in large numbers by an automatic carrying mechanism 12, and the sample grains in the drying box 11 are dried. During drying, as will be described later, the drying box 11 is taken in and out of the drying chamber 13 by the automatic loading mechanism 12, and the weight of the sample grains is repeatedly measured with the weighing scale 14A. It is assumed that the finishing moisture has been reached, and the sample grains in the finishing weighing scale 14A are conveyed to the next process.

The sample dryer 10B has the same configuration as the sample dryer 10A, so a description thereof will be omitted. In addition, 14 in the figure

．． Connect the switching valves 30A, 30B, and e respectively.

Next, a third example of the operation of the embodiment configured as described above will be explained.
This will be explained with reference to the figures.

Now, when grains are brought into the grain drying and preparation facility and, for example, the weighing of the grains is started by the weighing machine IA, the sample collector 2A collects sample grains during this weighing (step Sl).

When a predetermined amount of sample grains have been collected, the sample grains are transported by the cyclone 3 (step S2) and accommodated in the packets 7 of the packet type conveyor 6.

Next, when the packet type conveyor 6 is operated to transport the packets 7 toward the initial weighing scale 8A to the loss output end, the packets 7 are gradually tilted at the output end. As a result, the sample grains in the packet 7 are loaded into the initial weighing scale 8A, and during this loading period, the measured value of the weighing scale 8A is read and quantitative weighing is performed (step S3).

When the measured value of the weighing scale 8A reaches a predetermined relatively large amount (for example, IKg) (step S4), the packet type conveyor 6 is reversed to stop discharging the sample grains, and waits in this state. do.

Next, the initial moisture content of the sample grains accommodated in the initial weighing scale 8A is measured using the moisture meter 9A (step S5).

Next, the initial weight Wo of the sample powder corresponding to the measured moisture value mo is determined (step S6).

This initial weight Wo is a fixed finished weight W1 (for example, 1 kg) when the sample grains are dried to a finished moisture value m1.
The predicted weight corresponds to fi, which is calculated by adding the amount of heavy acid loss during the drying process to the mold part W1.

The initial weight Wo of this sample grain is the measured moisture value mQ, i + n, 1. Moisture value m1. It is calculated from the measured moisture value mQ and the initial weight W1 using a predetermined formula, but since the finished moisture value m1 and the finished weight W1 are known in advance, a correspondence table between the measured moisture value mQ and the initial weight WO is created in advance. Then, by table processing, the initial type #WO corresponding to each measured moisture value mo can be found in two series.

Next, the initial tonnage It of the sample grain determined in this way,
When W o is set (step S7), Hege again,
1. Rotate the conveyor 6 in the forward direction at low speed, and feed the remaining sample grains in the packet 7 into the initial weighing scale 8A, 11 at a time. During this time, the measurement value of the initial weighing scale 8A was changed to 1
When the measured value reaches the initial weight Wo (step S8), the conveyor 6 is reversed and all the remaining sample grains in the packet (7) are transferred into the other initial weight scale 8B. Dump it.

Next, the sample stored in the initial weighing scale 8A is discharged, but at that time, the switch j (3OA is in a state where the sample grains are led to the drying box 11 side, so all the sample grains are inside the drying box 1). Initial weight scale 8B
The surplus supplement grains dumped into the box 27 are thrown into the surplus box 27 via the switching valve 30Bt.

Next, the automatic transfer mechanism 12 is started and the drying box 11 containing the sample grains is carried into a predetermined drying chamber 13, and the sample grains start drying while remaining in the drying box 11 (step S9).

During this drying, at predetermined time intervals, the automatic transfer mechanism 12 takes out the drying box]1 from the drying chamber 13, and inserts the sample grains in the drying box]1 into the finishing mold ¥14A. The weight of the sample grains is measured (step A10). When the measured value does not reach the finished weight W1, the sample grains in the finish weighing scale 14A are returned to the drying box 11 and re-dried.

On the other hand, when the measured value reaches the finishing weight W1 (step 311), the sample grains in the finishing weighing scale 14A are guided into the distributor 15A.

Accordingly, according to the embodiment of the present invention, the self-testing device 22
The weight of each sample grain supplied to the machine and subjected to self-inspection is always constant (ie, finished weight Wt).

By the way, in the embodiment described in -1-1, the weight of the sample particles in the drying box 11 is measured at predetermined time intervals.
However, instead of this, the weight of the sample grains is
It is also possible to predict in advance the time when the sample grains become 1, and to measure the weight of the sample grains when this predicted time is reached.

(Effect of the invention) As described above, in the present invention, the sample dryer is used in the drying box 1]
Since the weight of the re-sample grains obtained at the time of testing is always constant, the weight of the sample grains subjected to self-verification by the self-testing device is constant. Therefore, if the present invention is connected to a self-testing device and used, it is possible to omit a weighing scale for measuring the weight of sample grains during self-testing, and it is also possible to omit the weighing scale that measures the weight of sample grains during self-testing. This eliminates the inconvenience of having different departments each time.
