Description

TECHNICAL FIELD The present invention relates to a measuring instrument that performs a plurality of measurements in parallel on an object to be measured, which is, for example, granular or powdery, and outputs respective measurement results.

Conventionally, rice grains produced by producers are inspected for quality and the like, and for this inspection, for example, a grain discriminator disclosed in Patent Document 1 is used. The grain discriminator includes a rotating plate with an inclined rotation axis, a data detecting section arranged on the outer peripheral portion of the rotating plate, and a data discriminating section connected to the data detecting section. On the outer peripheral edge of the rotating plate, a large number of storage recesses that are open in the outer direction and can store one grain are provided at predetermined intervals in the circumferential direction. The operation conveys the grains one by one to the data detector. A data detection part detects light reception data by irradiating the grain accommodated in the accommodation recessed part with light and imaging the state of the kernel. Then, the data discrimination unit determines the grade of each grain based on the received light data obtained by the data detection unit, and discriminates each grain into four types: dead rice, colored grain, cracked grain, and crushed grain. It has become so.

By the way, in addition to the indicators for knowing the quality of rice such as those disclosed in Patent Document 1, there are water content and volume weight as important indicators for knowing the quality of rice. Measurements are typically made using a measuring device.

Patent No. 4529700

However, when knowing the quality of the produced rice, after performing the discrimination work with a grain discriminator, the moisture content and volume weight of each rice grain are measured in order using a moisture meter and a volumetric weight measuring device. As a result, it takes a lot of time to finish all the tests. In addition, when a large amount of grains such as rice is measured in order by each measuring device, a large amount of grains must be put into each measuring device in order, and there is also a problem that the work is complicated. . Such a problem is not limited to the measurement of grains such as rice, but can also be applied to the measurement of other objects to be measured using a plurality of measuring instruments to obtain respective measurement results.

The present invention has been made in view of such a point, and its object is to output measurement results from a plurality of measurement units in the shortest time possible when measuring an object to be measured. To provide a measuring instrument capable of performing a simple measurement work.

In order to achieve the above object, the present invention provides a plurality of measuring units in a measuring machine, and divides an object to be measured into the measuring machine so that measurements in each measuring unit are performed in parallel. It is characterized by being introduced by

Specifically, the following countermeasures were taken for a measuring instrument configured to measure with a plurality of measuring units and output the measurement results respectively.

That is, in the first invention, one end has one input port for inputting the object to be measured, and the other end has a plurality of introduction ports for introducing the object to be measured into each of the measurement units, Distributing means is provided for guiding each of the objects to be measured inserted from the input port to the downstream side and distributing them to each of the introduction ports.

In a second aspect of the invention, in the first aspect, the distribution means has the inlet at one end, and is a main guide passage that guides each object to be measured that is introduced from the inlet while flowing down to the downstream side. and a plurality of branch guides each having an upper end opening in the middle of the main guide passage and each introducing port at a lower end for guiding each object to be measured guided in the main guide passage to each measuring unit. and a passage.

In a third invention according to the second invention, the main guide passage extends obliquely downward from one end toward the other end in a straight line, and each of the branch guide passages extends in the extension direction of the main guide passage. It is characterized by being arranged side by side with a predetermined interval along the line.

According to a fourth invention, in the third invention, each branch guide passage is provided with a shutter mechanism capable of switching the branch guide passage between a closed state and an open state.

In a fifth invention, in any one of the first to fourth inventions, the object to be measured is a grain, each of the measurement units is a volumetric weight measurement unit capable of measuring volumetric weight, and the grain and a grain discriminating unit capable of discriminating the grain type.

In the first invention, when the object to be measured is put into the inlet provided in the measuring machine, the distribution means divides the object to be measured and introduces them into the respective measuring units. Therefore, each measurement unit can perform measurements in parallel, and the time spent to complete all inspections can be shortened. In addition, since the distributing means distributes the objects to be measured to the respective measuring units when the operator puts the object to be measured once, the operator does not have to put the object to be measured into each measuring unit, which improves work efficiency. It can be a good measuring instrument.

In the second invention, the object to be measured that is put in through the inlet flows down the main guide passage by its own weight, and then, when it reaches the upper end opening of each branch guide passage, it drops down each branch guide passage by its own weight. Alternatively, it is introduced into each measuring unit while being guided along each branch guide passage by its own weight. Therefore, the object to be measured can be distributed to each measuring unit with a simple structure, and a low-cost measuring machine can be obtained.

In the third invention, since the dimension of the distribution means in the horizontal direction intersecting the extension direction of the main guide passage is shortened, the entire measuring machine can be made compact.

In the fourth invention, when the shutter mechanism is switched to the closed state and the object to be measured is introduced into the inlet, the object to be measured gradually accumulates from the side of the branch guide passage located on the upstream side of the main guide passage. That is, when the object to be measured accumulates in the branch guide passage up to its upper end opening position, the object to be measured flowing down the main guide passage crosses over the branch guide passage in which the object to be measured reaches the upper end opening position and flows down. It will accumulate in the branch guide passage located downstream of the guide passage. When the shutter mechanism is opened at a predetermined timing in a state in which all the branch guide passages are filled with objects to be measured, the objects to be measured are simultaneously introduced into each measuring unit through each introduction port. In this way, it is possible to simultaneously load the objects to be measured into the respective measuring units in a state in which the objects to be measured are divided into predetermined quantities for each measuring unit, so that the measurement conditions can be aligned. Each measurement can be performed efficiently in a state.

In the fifth invention, the volumetric weight, moisture content and appearance quality of grains can be efficiently determined in a short period of time using a single measuring device.

It is introduced into the unit 3, the volumetric weight measurement unit 4, and the moisture measurement unit 5, respectively. Therefore, the grain discriminating unit 3, the volumetric weight measuring unit 4, and the moisture measuring unit 5 can perform measurements in parallel, and the time spent to complete all inspections can be shortened. In addition, since the distributing unit 6 distributes the grains M1 to the grain discrimination unit 3, the volume weight measurement unit 4, and the moisture measurement unit 5 in one operation of throwing a large amount of grains M1 by the measurer, the measurer can The grain appearance quality inspection device 1 with good work efficiency can be obtained without the trouble of putting the grains M1 into each of the grain discrimination unit 3, the volumetric weight measurement unit 4 and the moisture measurement unit 5.例文帳に追加

Also, the grains M1 fed from the grain feeding port 2b flow down the main guide passage 7 due to their own weight, and then the upper end openings of the first branch guide passage 81, the second branch guide passage 82, and the third branch guide passage 83. , the first branch guide passage 81, the second branch guide passage 82, and the third branch guide passage 83 drop by their own weight, or the first branch guide passage 81, the second branch guide passage 82 by their own weight. , and the third branch guide passage 83 , respectively, and are introduced into the grain discriminating unit 3 , the volumetric weight measuring unit 4 , and the moisture measuring unit 5 . Therefore, the grains M1 can be distributed to the grain discrimination unit 3, the volumetric weight measurement unit 4, and the moisture measurement unit 5 with a simple structure, and the grain appearance quality inspection device 1 can be made at a low cost.

Also, the first branch guide passage 81, the second branch guide passage 82 and the third branch guide passage 83 are arranged side by side at predetermined intervals along the extending direction of the linear main guide passage 7. , the dimension in the horizontal direction intersecting the extension direction of the main guide passage 7 in the distribution unit 6 is shortened, and the entire grain appearance quality inspection device 1 can be made compact.

Further, when the first shutter mechanism 81b and the second shutter mechanism 82b are switched to the closed state and the grain M1 is thrown into the grain inlet 2b, the first branch guide passage 81 located upstream of the main guide passage 7 Grain M1 gradually accumulates. That is, when the grains M1 accumulate in the first branch guide passage 81 up to the upper end opening position, the grains M1 flowing down the main guide passage 7 pass through the first branch guide passage 81 in which the grains M1 are collected up to the upper end opening position. It climbs over and flows down, and accumulates in the second branch guide passage 82 located downstream of the first branch guide passage 81 . When the second branch guide passage 82 is filled with grains M1, the grains M1 flowing down the main guide passage 7 pass through the second branch guide passage 82 and enter the third branch guide passage 83, After being guided to the guide passage 83, it is introduced into the moisture measuring unit 5 through the third inlet 83a, and the moisture measuring unit 5 starts measuring the moisture content of each grain M1. On the other hand, when the first shutter mechanism 81b and the second shutter mechanism 82b are opened at a predetermined timing in a state in which the grains M1 are accumulated in the first branch guide passage 81 and the second branch guide passage 82, the grains M1 are moved to the second position. Through the first inlet 81a and the second inlet 82a, the grains are introduced into the grain discriminating unit 3 and the volumetric weight measuring unit 4 at the same time. In this way, a predetermined amount of grains M1 are divided into the grain discrimination unit 3 and the volumetric weight measurement unit 4, and the grains M1 are put into the grain discrimination unit 3 and the volumetric weight measurement unit 4. can be performed at the same time, each measurement can be performed efficiently under the same measurement conditions.

Furthermore, the grain appearance quality inspection device 1 according to the embodiment of the present invention can efficiently and quickly know the volumetric weight, the content moisture value and the appearance quality of the grain M1 with a single device.

In the embodiment of the present invention, a large amount of grains M1 are measured by the grain discrimination unit 3, the volumetric weight measurement unit 4, and the moisture measurement unit 5, respectively. The configuration may be such that each measurement unit measures another object to be measured. Moreover, the measurement unit is not limited to the three types of measurement units described above, and may be a measurement unit that performs other verifiable measurements.

In the embodiment of the present invention, the distribution unit 6 has three branch guide passages, but it may be two or four or more according to the number of measurement units to be measured.

Further, in the embodiment of the present invention, the first solenoid 81c, the second Although the solenoid 82e, the third solenoid 47b, and the fourth solenoid 43b are used, they are not limited to this, and may be operated by another drive source such as a gear motor.

Further, in the embodiment of the present invention, the first shutter mechanism 81b and the second shutter mechanism 82b are configured to open at the same time. The timing can be appropriately changed depending on the type and amount of the object to be measured, the frequency of measurement, or the like.

Further, in the embodiment of the present invention, after the upstream shutter mechanism 7b is opened, the level sensor 84 detects that the second branch guide passage 82 is full, and the upstream shutter mechanism 7b returns to its original position to be closed. However, the configuration is not limited to this, and after the upstream shutter mechanism 7b is opened and a predetermined time elapses, the upstream shutter mechanism 7b returns to its original position and becomes closed. may be
