[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to obtain a sample cell in which sample grains required for inspection are packed in a predetermined state when grains such as wheat are rapidly sorted at the stage of receiving the grains. And a method for filling grains in the sample cell.

[0002]

2. Description of the Related Art Conventionally, at the stage of receiving goods, the sorting of grains brought into small lots and carried in by small lots has been done by visual inspection by an inspector. Therefore, because no mechanical (automatic) sample inspection has been performed, only the grain is selected from the mixture of the grain and the contaminants, and this is filled in the sample cell in a state suitable for the inspection. for,
There was no grain filling device. Further, in the filling into the sample cell, it is necessary to fill the grain into the sample cell in a desired uniform and high filling rate,
There was no grain filling method that could achieve such a purpose.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to quickly provide a sample cell for inspection in which grains are packed at a predetermined density at the stage of receiving grains in which grains and impurities are carried as a mixture. The object is to obtain a grain filling device that can be obtained and a grain filling method adopted in this device.

[0004]

To achieve this object, the grain filling device according to the present invention is characterized by a grain separating section for separating the grain from a mixture of the grain and impurities, and a grain separating unit. At the lower part of the grain transfer path that carries out and transports the grains from the separating unit, a grain filling unit that drops and fills the grains into the sample cell is provided, and a sample cell vibrating unit that gives vibration to the sample cell is provided. There is something. Furthermore, the characteristic means of the method for filling a grain according to the present invention for achieving the above-mentioned object, while dropping the grain into the sample cell, imparts vibration to the sample cell to cause the sample cell to be filled with the grain, and filling. It is to increase the rate. The action and effect are as follows.

[0005]

In this grain filling device, the grain separation unit separates and sorts the grains from the impurities, and the grains are carried out to the grain transfer path side. A sample cell is vertically arranged at the downstream end of the grain transfer path, and the grains are dropped and stored and filled in the sample cell from the upper side. In addition, a vibrating means is provided for the sample cell, which is subjected to a rocking operation during this filling operation. Therefore, the grains are filled while dropping in the operating state, and a sample cell in a constant filling state is obtained. Furthermore, the method of filling the grain is
As described in the operating state of the apparatus described above, the grains are filled while dropping in the state of being supplied to the sample cell. In the case of this method, as the cell is filled, the grains that have already been stored (positionally located at the bottom) are automatically placed in the closest packed state due to vibration, and new grains are supplied from the top side. As a result, these are sequentially brought into the densest state and the filling proceeds. As a result, a good filling state of the grains in the sample cell can be obtained.

[0006]

As a result, at the stage of receiving a grain in which the grain and impurities are carried as a mixture, a grain filling device capable of quickly obtaining a sample cell for inspection in which the grain is filled with a predetermined density. By using this grain filling method, a grain filling method was obtained in which the filling state was sufficiently resistant to the subsequent inspection.

EXAMPLES A grain filling device 1 adopting the grain filling method of the present application will be described below, and this device 1 is used to analyze the grain attributes together with a spectroscopic analysis device (not shown), A grain sorting system capable of sorting small lots will be described.

In a large-scale drying facility such as an agricultural cooperative, grains (raw wheat, raw rice, etc.) received in small lot units are analyzed at high speed according to the receiving time, and sorting is performed based on the contents of the components. Although it is necessary to perform this, conventionally, this sorting work has been mainly performed manually.
For example, taking fresh wheat as an example, the loading to a large-scale drying facility is carried out in 2 to 3 minutes per car, and within this time, sorting is performed according to water content, appearance (color tone) and the like. In contrast to such conventional techniques, it has been attempted to measure physical properties of grains such as water, protein, and amylo value (stickiness) by a spectroscopic analyzer in a non-pulverized state, and sort by measured values. There is. The grain filling device 1 of the present invention is developed so that a sample with little variation suitable for inspection can be quickly obtained in this system. Here, the grain is raw, and is carried in while covering the shell, and in the carried-in state, the grain and foreign substances are carried in in a mixed state.

The construction of the grain filling device 1 will be described below with reference to FIG. FIG. 1 shows a sectional view of the grain filling device 1. The grain filling device 1 includes a grain separating unit 2 and a grain filling unit 3. The grain separation unit 2 is configured to include a sorting function plate 4 and a blower 5 for separating grains and impurities by wind sorting. As shown in the figure, the grain transfer path 6 through which the grains separated by the grain separation section 2 move is provided, and the lower region of the downstream end 6t of the grain transfer path 6 is the above-mentioned grain filling section. It is said to be 3.
In this grain filling unit 3, sample cells 7 in which grains are filled are vertically arranged, and in the vertically arranged state of the sample cells 7,
An exciter 8 is provided as a sample cell vibrating means for vibrating this in the lateral direction. Here, sample cell 7
Is a cylindrical container having an opening on the upper side, and a predetermined portion is formed of a transparent member 7a so that the inspection light can be transmitted in the lateral direction. The operation of the device will be described below.
In the above, the mixture of the grain and the contaminants air-transported from the apparatus inlet 1a is guided to the grain transfer path 6 side while the grain hits the sorting function plate 4 in the separation space 1b. On the other hand, the foreign matters are sucked by the blower 5,
The foreign matter is discharged from the foreign matter suction passage 1c, the blower portion 1d, and the foreign matter discharge port 1e. In this way, first, the removal of impurities is completed. Then, the grains falling from the grain transfer path 6 fall from the lower end portion 6t of the grain transfer path 6 and are filled in the sample cell 7 arranged at the lower position of this end portion. In this filling state, the sample cell 7 is oscillated in the lateral direction in the figure by the vibrating machine 8, and while the grains are being dropped and supplied, the filling density is adjusted by vibration until the filling density is close to the limit value. To be done.

That is, the grain filling apparatus 1 is provided with a sample cell mounting portion 9 provided with a vibrator 8 on the carry-out side of the transfer path 6 through which the grain after the removal of the contaminants is transferred. It is possible to simultaneously perform the removal and the vibration filling of the sample cell 7. Further, a series of measurement time including preparation of a sample sample and a spectroscopic analysis step described below is possible within 2 minutes.
