Description

Description: [Industrial application] The present invention relates to a grain refining device for performing grain refining for removing the outer coat of grain.

[Prior Art] A so-called cylindrical friction grain refining device using frictional force is used for grain refining.

In this type of grain refining device, a grain milling cylinder having a large number of through holes formed in the wall surface and a grain milling roll having a spiral protrusion formed on the outer peripheral surface thereof rotatably arranged in the grain milling cylinder are provided. I have it. Also, a grain tank is connected to the fine grain cylinder,
The grain can be fed into the fine grain cylinder. When performing grain refinement, the open / close valve of the grain tank is opened to feed grain between the grain cylinder and the grain roll, and the grain roll is rotated to perform grain refinement. ing.

In addition, a pressure device for adjusting the pressure of the grains to be refined in the refinement cylinder is arranged in this refiner, and by adjusting this, the degree of refinement of the grains can be changed. Has become. For example, in the case of brown rice, if the grain pressure is set high, the grain-refining action can be increased to produce white rice, while if the grain pressure is set low, the grain-refining action can be reduced to produce germ rice. Is able to.

By the way, even if grains are of the same type, there are grains that are easy to grind and grains that are difficult to grind, depending on the variety, region or crop. In order to treat the grain, it is necessary to treat the grain under a pressure condition adapted to the variety of the grain, a pressure condition adapted to the region, or a pressure condition adapted to the crop.

At the same time, some grains, even if they are of the same type, are soft or hard depending on the variety, region or pattern, that is, they are easily crushed when high pressure is applied. For example, it is necessary to reduce the grain refining time for a long time, and the grain refining time (pressurization time) needs to be treated under the conditions adapted to the grain.

Furthermore, in brown rice, different varieties may be mixed (blended) and supplied to the consumer as mixed polished rice. Even when mixed rice with different mixing ratios has the same grain refinement, the optimum grain pressure and The grain-refining time (pressurizing time) is different, and it is necessary to perform grain-refining even under the conditions adapted to the mixing ratio.

[Problems to be Solved by the Invention] In this respect, in the conventional grain refining apparatus, in order to set the degree of grain refining to a desired value, the treatment state is complicatedly monitored or treated experimentally at the initial stage of the treatment work. Therefore, it was necessary to repeat the readjustment while considering the result. For this reason, the work efficiency is poor, and a skilled worker is required to set the desired degree of grain refinement.

In consideration of the above facts, the present invention can be operated under the optimum conditions according to the grain to be refined to perform the refinement treatment, whereby a production efficiency is good and it is possible to obtain a refinement device which does not require the skill of the operator. Is the purpose.

[Means for Solving the Problem] A grain refining device according to the present invention supplies grains between a grain refinement cylinder and a grain refinement roll rotatably arranged in the grain refinement cylinder to rotate the grain refinement roll. A grain refining device for performing grain refining by storing a grain refining program for controlling a grain supply amount into the grain refining cylinder during grain refining and a grain pressure in the grain refining cylinder, and a device main body With respect to the external storage means configured to be removable, a supply amount detection means and a pressure detection means for detecting the grain supply amount into the refined grain cylinder and the grain pressure in the refined grain cylinder during grain refinement processing, According to the data input from the supply amount detecting means and the pressure detecting means during the grain processing, the grain supply amount into the grain grinding cylinder and the grain pressure in the grain grinding cylinder are automatically adjusted according to the grain processing program. And a control device for controlling, ing.

[Operation] In the grain refiner having the above-described configuration, the grain supply amount into the grain refinement cylinder and the grain pressure in the grain refinement cylinder depend on the data input from the supply amount detection means and the pressure detection means during grain refinement processing. It is automatically controlled according to the grain processing program. Therefore, by setting a large number of fine grain processing programs of the external storage means according to the conditions adapted to the region, the conditions adapted to the type of grain, the conditions adapted to the crop, the conditions adapted to the mixing ratio, etc., the user can The desired grain refinement program is selected and used, which allows grain to be milled under optimum conditions.

[Embodiment] FIG. 1 shows a sectional view of a grain refining device 10 according to a first embodiment of the present invention.

The grain refining device 10 is constituted by a frame 12 in a box shape that is vertically high. A guide tube suspension member 14 is attached to the upper part of the frame 12. A hopper 16 is placed on the guide tube suspension member 14, and the hopper 16 is further mounted on the hopper 16.
17 are connected. The grain tank 17 has a cylindrical shape in which the lower portion is squeezed into a funnel shape, and the grain is stored inside. The stored grains flow into the hopper 16 from the lower end opening by gravity.

An opening / closing door 19 is rotatably arranged in the hopper 16 and is further connected to a drive motor 21. This door
19 moves from a state where the inner cavity of the hopper 16 is opened to a state where the inner cavity of the hopper 16 is closed by the operation of the drive motor 21, whereby the grain such as brown rice flowing from the grain tank 17 and stretched into the grain refiner 10 The amount can be adjusted.

A guide cylinder 18 is fixed to the lower end of the guide cylinder suspension member 14. The guide cylinder 18 has a substantially cylindrical shape, a flange portion 20 projecting inward is formed at an upper end portion, and a convex portion 22 projecting outward is formed at an intermediate portion.

The upper end of the shaft 28 of the grain roll 26 is supported by the flange portion 20 via a bearing 24, and the vicinity of the lower end of the shaft 28 is supported by a flange 32 fixed to the frame 12 via a bearing 30. There is. Also, a pulley is attached to the lower end of the shaft 28.
34 is fixed and further connected to a drive device (not shown). Therefore, the fine grain roll 26 receives the driving force via the pulley 34 and rotates. A ring-shaped projection 36 is formed near the lower end of the grain roll 26 so as to project outwardly at an acute angle.

On the other hand, the worm wheel is located above the convex portion 22 of the guide tube 18.
38 is rotatably mounted. A worm gear 40 meshes with the worm wheel 38, and the worm gear 40 is fixed to a drive shaft of a motor 42. Therefore, the worm wheel 38 is adapted to rotate by receiving a driving force via the worm gear 40 as the motor 42 rotates.

A gear 39 is attached to a part of the worm wheel 38, and the gear 39 meshes with a gear 43 fixed to the rotary shaft of a potentiometer 41. Therefore, when the worm wheel 38 rotates, the gear 43 rotates accordingly, and the potentiometer 41 can detect the degree of rotation of the worm wheel 38.

Inside the lower end of the guide cylinder 18, the upper end support frame of the fine grain cylinder 44.
46 is inserted so as to be vertically movable and rotatable. A metered grain is supplied to the space between the fine grain cylinder 44 and the fine grain roll 26 by the opening / closing door 19 of the hopper 16.

A flow rate sensor 47 is arranged inside the upper end portion of the guide cylinder 18 so as to detect the amount of grain supplied to the fine grain cylinder 44 through the opening / closing door 19.

A flange portion 48 is formed on the upper end support frame 46 of the fine grain cylinder 44 so as to project outward. A link device 50 is attached between the flange portion 48 and the convex portion 22 of the guide cylinder 18, and a tension coil spring 52 is attached between the flange portion 48 and the worm wheel 38. Therefore, the flange portion 48 and the fine grain cylinder 44, when the grain pressure between the fine grain cylinder 44 and the fine grain roll 26 (fine grain chamber) becomes high,
By the action of the link device 50, the link device 50 moves downward about the axis while resisting against the tensile force of the tension coil spring 52. Further, when the worm wheel 38 rotates, the locking position of the tension coil spring 52 changes, so that the biasing force of the tension coil spring 52 can be changed. Therefore, the biasing force of the tension coil spring 52 can be indirectly detected by the potentiometer 41 that detects the degree of rotation of the worm wheel 38.

Further, a large number of through holes 54 are formed in the middle portion of the grain refinement cylinder 44 so that the outer skin such as bran peeled from the brown rice can pass to the outside.

A ring-shaped projection 56 is formed at the lower end of the refined grain cylinder 44 so as to project inwardly at an acute angle, and the tip thereof is normally in contact with the protrusion 36 of the refined grain roll 26. Therefore, in this state, the grain remains between the mill roll 26 and the grain cylinder 44, but when the grain cylinder 44 moves downward and the protrusion 56 separates from the protrusion 36, a gap is generated. It is designed to flow downwards through.

Below the refined grain cylinder 44, a grain extraction cylinder 58 is arranged so as to be continuous with the inside of the refined grain cylinder 44, and the grains flowing out from between the protrusions 56 and 36 are outside the grain refiner 10. It can be taken out. Further, a bran discharge tube 60 is arranged below the grain extracting cylinder 58 so as to be continuous with the outside of the refined grain cylinder 44 (through hole 54). Can be discharged to the outside of the grain refiner 10.

A control panel 62 is provided on the front surface of the grain refining device 10 (on the left side in FIG. 1), and in this control panel 62, a connector 66 for mounting a storage section 64 of the control device is arranged as shown in FIG. Has been done. The connector 66 is formed in a box shape with one end open in the longitudinal direction, and both ends in the width direction are guide portions 66A having a U-shaped cross section. A plurality of connecting pins 68 are attached to the other end in the longitudinal direction so as to project inward. This connection pin 68
Is connected to a control circuit described later.

A dustproof lid 70 is arranged in front of the control panel 62 in front of the connector 66, and the connector 66 is protected from dust by closing the lid.

The storage unit 64 is a thin-card-shaped semiconductor storage device, and one end portion 64A in the longitudinal direction has a power supply, address, data, write enable (WE), output enable (OE),
Each terminal such as a chip enable (CE) is arranged so as to correspond to the connection pin 68 of the front connector 66. Each of these terminals has a concave shape so that the connection pin 68 of the connector 66 can be fitted therein. Therefore, the terminals and the connecting pins 68 can be fitted and removed without using a special tool.
Therefore, when the storage part 64 is inserted into the connector 66 from the one end 64A in the direction of arrow A in FIG. 2 after the dustproof cover 70 is opened, the storage part 64 is guided along the guide part 66A formed on the connector 66, and then the inside of the connector 66 is guided. The connection pin 68 arranged at and the respective terminals of the storage unit 64 are adapted to be fitted to each other. In this case, since the support (detection) terminals are arranged in the storage unit 64 and the support pins are attached to the connectors 66 respectively, the storage unit 64 is prevented from being inserted upside down. is doing. When removing the storage unit 64, it may be removed as it is.

Both a read only memory (ROM) and a random access memory (RAM) are mounted in the storage unit 64, and are connected to the respective terminals.

The ROM stores a grain processing program for grain flow rate control and grain pressure control, which is determined according to the region, the type of grain, the pattern, or the mixing ratio. Therefore, the grain refiner is adapted to perform grain refinement according to this grain refinement program.

The storage unit 64 has a built-in backup battery and is connected to the RAM. Therefore, when the current supply from the power supply is cut off (for example, the storage unit 64 is connected to the connector 66
If you remove it from), you can save the memory as it is in RAM.

Further, this storage unit 64 stores different grain processing programs in the ROM (that is, grain processing programs for grain flow rate control and grain pressure control determined according to region, grain type, cropping or mixing ratio). A variety of stored items are prepared so that the user can freely select his / her preference.

As shown in FIG. 3, the storage section 64 is connected to the control circuit of the grain refiner 10 by inserting it into the connector 66. The control circuit includes a central processing unit (CPU) 72, an input circuit 74, an output circuit 76, and a bus connecting these. The above-mentioned potentiometer 41 and flow rate sensor 47 are connected to the input circuit 74. Further, the output circuit 76 includes the relay circuit 77 of the drive motor 21 and the motor 42.
The relay circuit 78 of is connected.

Next, the operation of this embodiment will be described.

When operating the grain refiner 10, one of the variously prepared storage units 64 in which a desired program is stored is selected and inserted into the connector 66 of the control panel 62. As a result, the storage unit 64 is connected to the central processing unit (CPU) 72 in the control circuit.

Further, the fine grain roll 26 is rotated and the grain is fed from the hopper 16 to the fine grain cylinder 44. This starts the grain processing. When the grain flows into the fine grain cylinder 44, frictional pressure is generated, which causes the grain to be milled.

When the frictional force between the grain mill roll 26 and the grain grain cylinder 44 increases and the grain pressure in the grain grain cylinder 44 increases, the grain grain cylinder 44 has the grain pressure in the grain grain cylinder 44 of the tension coil spring 52. Move diagonally downward until the state corresponding to the biasing force is reached. When the refined grain cylinder 44 moves downward, a gap is created between the protrusion 36 of the refined grain roll 26 and the protrusion 56 of the refined grain cylinder 44, and this gap serves as a grain passage for discharging the grain after grain refinement. Grain take-out cylinder 58
Be taken out through. Further, the outer skin such as bran peeled from the grain passes through the through hole 54 of the fine grain cylinder 44 to the outside and is discharged through the bran discharge tube 60.

In this grain processing, the central processing unit (CPU) 72 is based on the signals from the flow rate sensor 47 and the potentiometer 41 input through the input circuit 74, and the grain processing stored in the ROM of the storage unit 64. Process according to the program. 4 and 5 show an example of the control routine in this case.

When the grain refiner 10 is operated, the grain pressure P detected and converted by the potentiometer 41 is read in step 100, and the grain pressure read in step 100 in step 102 is set to a preset grain pressure Po. Be compared.

If the grain pressure P and the set grain pressure Po are the same, the grain pressure adjusting process is ended. When the grain pressure P is higher than the set grain pressure Po, the motor 42 is rotated clockwise in step 104, the worm wheel 38 rotates in the same direction as the rotation direction of the grain roll 26, and the support position of the tension coil spring 52 is increased. To reduce its bias. As a result, the grain cylinder 44 moves further downward, the distance between the protrusion 36 and the protrusion 56 increases, and the grain pressure P decreases.

On the other hand, when the grain pressure P is lower than the set grain pressure Po, the motor 42 is rotated counterclockwise in step 106, and the worm wheel 38 is rotated in the direction opposite to the rotation direction of the fine grain roll 26.
Rotates to change the support position of the tension coil spring 52 and increase its urging force. As a result, the grain cylinder 44 moves upward, the distance between the protrusion 36 and the protrusion 56 decreases, and the grain pressure P increases. In this way, the grain pressure in the grain refinement cylinder 44 is automatically controlled according to the set program to perform grain refinement.

On the other hand, in the grain supply amount adjusting process, step 108
Supply amount W detected by flow sensor 47 at
Is read, and the grain supply amount W read in step 108 in step 110 is the preset grain supply amount.
Compared to Wo.

If the grain supply amount W and the set grain supply amount Wo are the same, the grain supply amount adjustment processing ends. When the grain supply amount W is smaller than the set grain supply amount Wo, the drive motor 21 is rotated clockwise in step 112, and the opening / closing door 19 is rotated in the direction to open the inner cavity of the hopper 16. As a result, the grain supply amount W increases.

On the other hand, when the grain supply amount W is larger than the set grain supply amount Wo, the drive motor 21 is rotated counterclockwise in step 114, and the opening / closing door 19 is rotated in the direction to close the inner cavity of the hopper 16. This reduces the grain supply W.

In this way, the amount of grain supplied into the grain refinement cylinder 44 is automatically controlled according to the set program to perform grain refinement. Therefore, if the grain pressure in the grain cylinder 44 is set to a predetermined pressure, the opening / closing door 19 is rotated to increase or decrease the grain supply amount, whereby the grain flow rate and the pressurizing time in the grain cylinder 44 are increased. Can be varied (for example, increasing the grain supply also increases the grain flow in the grain cylinder 44 in an attempt to maintain it at a given pressure, which reduces the pressurization time. ), The grain can be milled in a pressure time (grain processing time) adapted to the grain to be milled.

In this case, the grain supply amount into the fine grain cylinder 44 is not limited to being detected by the flow rate sensor 47, but a potentiometer is arranged on the rotary shaft of the opening / closing door 19 to detect the opening degree of the opening / closing door 19,
The supply amount may be calculated by this.

The storage unit 64 can be easily inserted into or removed from the connector 66 of the control panel 62 without using a special tool after opening the dustproof cover 70 as shown in FIG. A person can operate the grain refiner 10 by freely selecting a grain refinement processing program adapted to a desired regional condition, a variety of grains, or a mixing (blending) ratio of different varieties. Therefore, by preparing a plurality of types of storage unit 64, it becomes possible to perform grain processing suitable for the region with a single model in any region of the country,
Further, it is possible to set a desired degree of grain refinement without requiring skilled techniques, and work efficiency is improved and cost can be reduced.

Further, since the storage unit 64 has a compact shape, even if the user prepares a plurality of types, storage management can be easily performed.

Furthermore, the storage section 64 has a built-in backup battery and is connected to the RAM, so that the storage can be maintained. That is, since the grain processing data such as the grain supply amount, the grain pressure during the grain processing, and the time required for the grain processing can be stored in this RAM, the storage unit 64 can be collected and analyzed. For example, the best grain processing program can be determined at the time of program creation at a later date, and the experiment can be performed under other conditions, which can be effectively used.

In the present embodiment, the storage unit 64 has both a ROM and a RAM and has a built-in backup battery. However, the present invention is not limited to this, and only one of them may be used. That is, if it is desired to be able to change the grain processing program, only the ROM needs to be provided, and if the grain processing data is to be stored and further removed and analyzed, only the back-up RAM needs to be provided. In these cases, the storage unit 64
Can be even more compact.

Further, in the present embodiment, the memory unit 64 is a card-shaped semiconductor memory device, but it is not limited to this, and may be a magnetic memory device, and may be a cassette-shaped or disk-shaped one.

Next, a second embodiment of the present invention will be described. The same reference numerals as those in the first embodiment are given to those basically the same as those in the first embodiment, and the description thereof is omitted.

In the control panel 62 on the front of the grain refiner 10, a grain refinement control circuit is arranged as in the first embodiment. As shown in FIG. 6, the control circuit includes a storage unit 80, a central processing unit (CPU) 72, an input circuit 74, an output circuit 76, and a bus connecting these.

In the ROM, the grain supply amount into the grain cylinder 44 and the grain cylinder 4
A basic grain processing program for controlling grain pressure in 4 is stored. Further, the ROM stores the data of the grain supply amount and the grain pressure determined according to the region, the variety, the crop and the mixing ratio for each code, and the control contents can be changed.

In addition, a plurality of types of data corresponding to each condition are coded and stored. For example, as shown in Table 1, in the case of processing “Sasashishiki” grown in the “Hokkaido” region as “super polished rice”, the optimum grain supply is “10 l / H” and the optimum grain pressure is "10l / H" and "high pressure at the early stage of grain refinement, gradually decreasing from the middle stage to low pressure at the latter stage" The data "It becomes pressure" is stored as the code number "0009", or "Sasashishiki" grown in the "Tohoku" area mixed with 5% of "Koshihikari" is treated as "embryo rice". In this case, if the optimum grain supply is "20 l / H" and the optimum grain pressure is "high pressure from the early to middle stage of the grain refinement and low pressure in the latter period", High pressure from the beginning to the middle period and low pressure in the latter period ” Say data is code number "1051"
Is remembered as In addition, similarly to this, data is coded and stored for the product type and the design.

Each of these coded data is further displayed as a bar code, and is prepared as one bar code collection or bar code label collection. Therefore, the user can select the bar code corresponding to desired data according to the grain to be dried.

A relay circuit 77 for the drive motor 21 and a relay circuit 78 for the motor 42 are connected to the output circuit 76. Further, the input circuit 74 includes the potentiometer 41 and the flow sensor described above.
47 are connected to each, and a receiver 82 is further connected. The receiver 82 is arranged on the front surface of the control panel 62, and can receive a radio signal from the bar code reader 84 and supply the signal to the input circuit 74.

As shown in FIG. 8, the bar code reader 84 contains a light source 86 and a lens 88, and is further connected with a sensor 90, a decoding 92 and a transmitter 94. The bar code reader 84 can read the bar code 96, convert the code number into an electric signal, and then transmit the electric signal to the outside. The transmitted signal is received by the receiver 82 and then supplied to the central processing unit (CPU) 72 via the input circuit 74. The central processing unit (CPU) 72 selects the data corresponding to the code number among the stored data based on this signal, and the grain refinement processing program is determined by this. As described above, when the user reads the desired bar code 96 with the bar code reader 84, data corresponding to the region, the type of grain, the pattern and the mixing ratio is automatically input to the control circuit. .

Next, the operation of this embodiment will be described.

When operating the grain refiner 10, the operator selects one of the various barcodes 96 corresponding to the desired grain refinement condition and reads it by the barcode reader 84 as shown in FIG. The bar code reader 84 converts the read optical signal into an electric signal and then transmits the electric signal. The transmitted signal is received by the receiver 82 arranged on the control panel 62 and then supplied to the central processing unit (CPU) 72 via the input circuit 74.

The central processing unit (CPU) 72 considers the signals from the potentiometer 41 and the flow rate sensor 47 input via the input circuit 74 based on the set optimum grain processing program, and the relay circuit via the output circuit 76. Outputs operation signals to 77 and 78. Therefore, the motor 42 is driven, the biasing force of the tension coil spring 52 is automatically adjusted, the grain pressure in the fine grain cylinder 44 is automatically controlled, and the drive motor 21 is rotated to rotate the opening / closing door 19 to perform the fine adjustment. The grain supply amount into the grain cylinder 44 is automatically controlled.

Thus, in the present embodiment, when operating the grain refiner 10,
Only by reading the bar code 96 with the bar code reader 84, it is possible to set the desired data, that is, the refinement processing control adapted to the variety or region of the grain to be refined or the mixing ratio, so that the refinement apparatus 10 can be operated under the optimum conditions. You can Therefore, regardless of the region of the whole country and the variety and the pattern are different, it becomes possible to process the fine grain suitable for the grain with a single model, and the cost can be reduced.

In the present embodiment, the ROM is used to store various coded data and the selection signal is converted into a bar code. However, the present invention is not limited to this, and each data necessary for setting the grain processing program is directly bar coded. The barcode may be read by the barcode reader 84.

Furthermore, in the present embodiment, the data read by the bar code reader 84 is photoelectrically converted and then transmitted as a radio signal, but the present invention is not limited to this, and the control circuit for the grain refiner 10 that transmits by an optical signal or a sound wave signal is used. It may be configured to supply to. Further, the barcode reader 84 and the control circuit may be directly connected by an electric cable. In this case, the receiver 82 and the transmitter 94 are unnecessary, and the structure is simple.

Furthermore, a selection button may be arranged on the control panel 62, and various data stored in the ROM may be selected by this selection button.
