JP 2000-334317 A

  In the above-described conventional configuration, when the rice milling process is performed, the user operates the whiteness setting unit, so that any one of a plurality of preset reference whiteness levels can be obtained. In such a configuration, whiteness other than the reference whiteness of the plurality of steps cannot be selected, so that the change adjustment to finer whiteness can be performed. For users who want to use this, it has become inconvenient.

  In addition, for example, users who wish to make finer adjustments to whiteness, for example, recently want a lower whiteness level where the starch layer containing nutrients remains in the surface layer of rice. Such users may generally desire to be highly health conscious and to change whiteness finely. However, in the above-described conventional configuration, whiteness other than the reference whiteness of the plurality of stages cannot be selected, and therefore it is necessary to cope with the user's preference for such a finer whiteness change adjustment. It was not easy to use.

  By the way, among the unspecified number of users who use the rice milling equipment, other users other than the user who desires the fine whiteness change adjustment as described above, the whiteness setting means In many cases, it is only necessary to select one of the reference whiteness levels of the plurality of steps set by operating, and fine whiteness change adjustment is not necessary. However, there is a disadvantage that it is difficult to handle if the whiteness change adjustment is performed so that it can be changed in addition to the reference whiteness.

  An object of the present invention is to provide a rice milling treatment facility that can be adjusted to whiteness according to user's preference in a form that is easy for a large number of users to handle.

The rice milling processing facility according to the present invention includes a rice milling process unit that performs a rice milling process on the processing target rice that has been input to the input unit and discharges it to the take-out unit, and a whiteness adjusting unit that changes and adjusts the whiteness adjustment state in the rice processing unit. A manually operated whiteness setting means for instructing any of a plurality of reference whiteness information corresponding to a plurality of preset reference whiteness levels, the rice milling means, and the whiteness adjustment means Operation control means for controlling the operation of the system, and the operation control means satisfies an operation start condition determined in a state including at least compensation payment information indicating that compensation for the use of the facility has been paid. The rice milling means performs the rice milling process in the rice milling means and adjusts the whiteness adjusting means to a whiteness adjustment state corresponding to the reference whiteness information commanded by the whiteness setting means. And said Be those that are configured to perform rice operation control process for controlling the operation of the degree adjusting means,
The first characteristic configuration is a manually operated whiteness fine adjustment for instructing fine adjustment information for at least one reference whiteness information among a plurality of reference whiteness information instructed by the whiteness setting means. Means as the fine adjustment information, information corresponding to an unadjusted state in which the reference whiteness information is not finely adjusted, information for fine adjustment to the whiteness increasing side with respect to the reference whiteness information, and the reference whiteness information It is provided in a state where it is possible to command information for fine adjustment to the whiteness reduction side,
The operation control means is
When the reference whiteness information to be finely adjusted by the whiteness fine adjustment unit is commanded by the whiteness setting unit, the reference whiteness information commanded by the whiteness setting unit and the whiteness The rice milling operation control process is executed in such a manner that the whiteness adjusting means is adjusted to the whiteness adjustment state corresponding to the adjusted whiteness information obtained based on the fine adjustment information commanded by the fineness adjusting means. And
When a reset determination condition defined as a condition for resetting the whiteness fine adjustment means is satisfied, a reset process is executed to return the whiteness fine adjustment means to a state instructing information corresponding to the non-adjustment state. The point is that it is configured to do.

  According to the first characteristic configuration, when the reference whiteness information to be fine-adjusted by the whiteness fine adjustment unit is instructed by the whiteness setting unit, the operation control unit has the whiteness The whiteness adjustment means is brought into a whiteness adjustment state corresponding to the adjustment whiteness information obtained based on the reference whiteness information commanded by the setting means and the fine adjustment information commanded by the whiteness fine adjustment means. The rice milling operation control process is executed in the form of adjustment.

  In other words, when the operation start condition such as the user putting the processing target rice into the input unit and paying the compensation is satisfied, the rice milling means starts the rice milling process and selects the processing target rice. The rice is treated and discharged to the take-out section, and it is confirmed whether or not the desired whiteness is obtained by visually observing the treated rice that has been subjected to the rice treatment and discharged to the take-out section. At that time, the reference whiteness information to be finely adjusted by the whiteness fine adjustment means is commanded by the whiteness setting means, and the whiteness of the processing target rice discharged to the take-out unit is desired whiteness When the user commands the fine adjustment information for the reference whiteness information by manually operating the whiteness fine adjustment means, the adjustment obtained based on the fine adjustment information for the reference whiteness information. Since the whiteness adjusting means is adjusted to the whiteness adjustment state corresponding to the whiteness information, the whiteness of the processing target rice that is actually subjected to the rice milling process is changed and adjusted in the rice milling process.

  When the fine adjustment information of the whiteness fine adjustment means is described, when information corresponding to an unadjusted state in which the reference whiteness information is not finely adjusted is commanded as the fine adjustment information by the whiteness fine adjustment means. The adjusted whiteness information corresponds to the reference whiteness information commanded by the whiteness setting means. Further, when the whiteness fine adjustment means instructs the fine adjustment information to finely adjust the whiteness increase side with respect to the reference whiteness information, the adjusted whiteness information is instructed by the whiteness setting means. The reference whiteness information is finely adjusted to the whiteness increasing side. When the whiteness fine adjustment means instructs the fine adjustment information to finely adjust the whiteness reduction side of the reference whiteness information, the adjusted whiteness information is instructed by the whiteness setting means. The reference whiteness information is finely adjusted to the whiteness reduction side.

  In other words, if the whiteness of the rice to be processed after the rice milling process is different from the whiteness desired by the user, the user instructs the fine adjustment information by the whiteness fine adjustment means, so that the process after the rice polishing process is performed. It is possible to change and adjust the whiteness adjustment state in the rice milling means so that the whiteness of the target rice becomes the whiteness desired by the user. As a result, it is possible for a user who desires a fine adjustment of the whiteness to adjust the whiteness according to his / her preference in an easy-to-use manner of operating the whiteness fine adjustment means.

  Then, when a reset determination condition defined as a condition for resetting the whiteness fine adjustment means is satisfied, the operation control means executes the reset process to place the whiteness fine adjustment means in the unadjusted state. It returns to the state which commands the information corresponding to. As the determination condition for resetting, for example, the condition corresponding to the fact that the user who has been using the equipment until that time has finished using the equipment, etc., the state of fine adjustment by the whiteness fine adjustment means is not adjusted. This is a condition for returning to the state corresponding to the state.

  As a result, when another user introduces the rice to be treated and starts the rice milling process, the whiteness fine adjustment means has returned to a state in which information corresponding to the non-adjustment state is commanded. Even if the fineness adjusting means is not operated, the whiteness adjusting means is adjusted to the whiteness adjusting state corresponding to the reference whiteness information commanded by the whiteness setting means.

  By the way, instead of such a configuration, for example, even when the user has finished using the equipment, the previous user adjusted the whiteness fine adjustment means without executing the reset process. Although it is conceivable to keep the fine adjustment information in a commanded state, in this type of milling processing equipment, it is used by an unspecified number of users. When the fine adjustment means is operated to the adjustment position desired by the user and the rice milling process is performed, for example, another reference that does not require fine adjustment with respect to the reference whiteness information commanded by the whiteness setting means. If the user forgets to return to the state in which the whiteness fine adjustment means commands information corresponding to the non-adjusted state when the milling process is performed, the whiteness fine adjustment means is adjusted by the previous user. To command the fine adjustment information Since is maintained, there is a risk that processed rice whiteness after being actually milled is what the user that is different from the whiteness desired. In this way, the user who does not need to finely adjust the reference whiteness information is rather unusable.

  On the other hand, according to the first characteristic configuration, when another user different from the previous user uses the equipment, the whiteness fine adjustment means commands information corresponding to the non-adjustment state. The whiteness adjustment means is brought into a whiteness adjustment state corresponding to the reference whiteness information commanded by the whiteness setting means without performing any operation on the whiteness fine adjustment means. Therefore, even if it is used by another user who does not need to make fine adjustments to the reference whiteness information, the whiteness can be adjusted according to the user's preference in an easy-to-use form. It becomes possible to do.

  Therefore, according to the 1st characteristic composition, it came to be able to provide the rice mill processing equipment which can be adjusted to whiteness according to a user's liking in the form which many users can handle easily.

  In addition to the first feature configuration, the second feature configuration of the present invention includes a plurality of levels of fine adjustment amounts as information that the whiteness fine adjustment unit finely adjusts to the whiteness increase side with respect to the reference whiteness information. A plurality of corresponding information can be commanded, and a plurality of pieces of information corresponding to a plurality of fine adjustment amounts can be commanded as information for fine adjustment to the whiteness decreasing side from the reference whiteness information. In the point.

  According to the second characteristic configuration, when the user manually operates the whiteness fine adjustment means and instructs the fine adjustment information, the fine adjustment information is finer on the whiteness increasing side than the reference whiteness information. When commanding the information to be adjusted and the information to finely adjust to the whiteness decreasing side from the reference whiteness information, it is possible to command a plurality of information corresponding to a plurality of levels of fine adjustment amounts. Since the fine adjustment amount is finely adjusted, the user has experienced whether the whiteness of the processing target rice is in a desired state by adjusting the whiteness fine adjustment means to which fine adjustment amount among a plurality of steps. By knowing, for example, it is possible to determine the fine adjustment amount as a guide when performing fine adjustment operation to achieve the desired whiteness, compared to a configuration where fine adjustment is performed steplessly. It becomes easy to operate.

  Therefore, according to the second characteristic configuration, it is possible to provide a rice milling facility that makes it easy to determine a guideline for fine adjustment and facilitates the fine adjustment operation.

  According to a third feature configuration of the present invention, in addition to the first feature configuration or the second feature configuration, the whiteness fine adjustment unit is more than the information finely adjusted to the whiteness increase side than the reference whiteness information. The information that finely adjusts to the whiteness decreasing side rather than the reference whiteness information is configured to command a larger fine adjustment amount.

  Among users who use this type of rice processing equipment, for example, users who desire a larger whiteness corresponding to the whiteness of standard white rice are required to finely adjust the whiteness over a large range. However, users who desire a lower whiteness with a large amount of starch layer containing nutrients in the surface layer of rice generally have a high degree of health and a fine range of whiteness. Tend to want to be able to

  Therefore, the information for fine adjustment to the whiteness decrease side rather than the information for fine adjustment to the whiteness increase side than the reference whiteness information is configured to instruct a larger fine adjustment amount. When finely adjusting to the whiteness increasing side, the fine adjustment amount is not so large, but when finely adjusting to the whiteness decreasing side, a large fine adjustment amount is commanded. It becomes easy to perform over a large range, and it becomes easy to perform a fine adjustment operation for instructing fine adjustment information corresponding to the desired whiteness.

  Therefore, according to the 3rd characteristic structure, it came to be able to provide the rice mill processing equipment which can make it easy to perform fine adjustment operation.

  According to a fourth feature configuration of the present invention, in addition to any of the first feature configuration to the third feature configuration, the whiteness fine adjustment unit is configured to perform the fine adjustment based on temperature information or season information of the processing target rice. The fine adjustment amount corresponding to the information is corrected.

According to the fourth characteristic configuration, the whiteness fine adjustment unit corrects the fine adjustment amount corresponding to the fine adjustment information based on the temperature information or the season information of the processing target rice. For example, if the temperature of the rice to be treated is different, or the season in which rice is polished is different, for example, in summer and winter, for example, even if the same information is commanded as the fine adjustment information, Later whiteness may be different.
In other words, when the rice to be treated at high temperature is polished, or when rice is polished in the summer when the humidity and temperature are high, the rice to be treated has a relatively high moisture content and is relatively soft. In the rice milling process, the surface layer of rice tends to be whitened. On the other hand, when milling low-temperature processing target rice, or when milling rice in winter when humidity and temperature are low, the processing target rice has a low moisture content and is relatively hard, There is a tendency that the surface layer of rice is not easily whitened.

  Therefore, by correcting the fine adjustment amount corresponding to the fine adjustment information based on the temperature information or season information of the processing target rice, it corresponds to the difference in temperature and season of the processing target rice when performing the rice milling process. Appropriate fine adjustment information can be commanded, for example, even if the temperature and season of the processing target rice are different, if the same fine adjustment information is commanded, the whiteness after milling can be the same, There is no trouble of commanding different fine adjustment information, and the fine adjustment operation can be performed in an easy-to-handle form.

  Therefore, according to the fourth feature configuration, the whiteness after the rice milling process can be the same if the same fine adjustment information, regardless of the temperature difference or season difference of the processing target rice, It has come to be able to provide a rice milling facility that enables fine adjustment operations in an easy-to-handle form.

  The fifth characteristic configuration of the present invention is that, in addition to any of the first characteristic configuration to the fourth characteristic configuration, the whiteness fine adjustment means is provided in the vicinity of the extraction portion.

  According to the fifth characteristic configuration, since the whiteness fine adjustment means is provided in the vicinity of the take-out part, the user can determine the actual whiteness of the processing target rice after the rice milling process discharged from the take-out part. While visually confirming, fine adjustment information can be commanded so as to achieve a desired whiteness by manually operating whiteness fine adjustment means provided in the vicinity of the take-out portion.

  Therefore, according to the fifth characteristic configuration, the user operates the whiteness fine adjustment unit in a state in which appropriate fine adjustment information is instructed while visually confirming the actual whiteness of the processing target rice after the rice milling process. It has become possible to provide rice milling facilities that are easy to use for users.

  In addition to any of the first to fifth feature configurations, the sixth feature configuration of the present invention is a work space in which a user enters and exits for work on the input portion and the take-out portion in the rice milling means. A human body presence / absence detecting means for detecting whether a user is present in the work space or a non-existing state in which the user is present in the work space, and the operation control The means is configured to determine that the reset determination condition is satisfied when the usable time set corresponding to the consideration has elapsed and the human body presence detection means detects the non-existing state. There is in point.

  According to the sixth characteristic configuration, the user brings his / her processing target rice into the work space, puts it into the input section, and pays for the use of the facility. Then, when the rice milling process is completed, the processing target rice discharged from the take-out unit is taken out, and then left out of the work space.

  Therefore, when the operation control means detects that the usable time that has been set corresponding to the price has passed and the human body presence detection means does not exist in the work space, the user is not present. It is determined that the use of the equipment by the user has been completed and the determination condition for reset is satisfied, and the whiteness fine adjustment means is reset to return to a state instructing information corresponding to the non-adjustment state. It is.

  By the way, as the determination criterion for resetting, for example, a configuration may be adopted in which it is determined that the resetting determination criterion is satisfied as soon as the milling process is completed after the usable time set corresponding to the consideration has elapsed. However, with such a configuration, when the amount of processing target rice to be processed is large and the processing cannot be divided by a single rice polishing process, the same user may perform the rice polishing process multiple times. However, in such a case, the reset process is executed every time the rice milling process is completed, and the user must readjust the fine adjustment information each time the rice milling process is started. However, the operation is troublesome, but by setting the above-described reset determination condition, the reset is not performed while the same user is in the work space. Interest is not.

  Therefore, according to the sixth feature configuration, it has become possible to provide a rice milling treatment facility that can perform a rice milling process satisfactorily without troublesome operations such as readjustment of fine adjustment information.

Can be placed.

  As shown in FIG. 1, an operation control panel 60 is disposed so that the front surface of the cabin 3 faces the cabin 3. The front portion of the operation control panel 60 is instructed to either a coin insertion slot 61 for inserting coins as a consideration for the use of equipment or a plurality of reference whiteness information corresponding to a plurality of levels of reference whiteness. A plurality of whiteness selection buttons 62 are provided as manual operation whiteness setting means. Inside the operation control panel 60, as shown in FIG. 6, a coin detector 63 that outputs consideration payment information indicating that a coin has been inserted from the coin insertion portion 61, that is, the consideration has been paid, Based on a plurality of detection switches S1 to S4 that detect operations of the plurality of whiteness selection buttons 62, compensation payment information of the coin detector 63, reference whiteness information commanded by the whiteness selection button 62, and the like. A control unit 64 including a microcomputer for controlling the rice milling machine 11 and the opening adjusting motor 34 is provided. Therefore, the operation control means 100 is configured using the control unit 64. Although not shown in FIG. 6, the control unit 64 includes the tension elevator 10, the rice mill 12, and each device for discharging rice bran that convey the processing target rice put into the feeding hopper 8 to the rice mill 11. This will also control the operation.

As shown in FIG. 9, the whiteness selection button 62 includes a “partial” whiteness selection button 62a, a “standard” whiteness selection button 62b, an “upper white” whiteness selection button 62c, and a “clean” whiteness selection. There are four buttons 62d. Among them, when the “standard” whiteness selection button 62b is operated, a reference whiteness set as a standard value is selected in advance, and when the “upper white” whiteness selection button 62c is operated. When the standard whiteness that is higher than the standard whiteness is selected and the “clean” whiteness selection button 62d is operated, the whiteness is higher than that of “upper white” and is sharpened with water before cooking rice. Whiteness equivalent to so-called no-wash rice that can reduce the number of operations is selected.
In addition, when the “percentage” whiteness selection button 62a is operated, a whiteness level of 7 minutes is basically selected as the reference whiteness. As described later, this “percentage” whiteness selection button is selected. The whiteness can be finely adjusted when 62a is operated.

  That is, in this rice milling equipment, at least one reference whiteness information of the plurality of reference whiteness information commanded by the whiteness selection button 62, specifically, the whiteness of “split” The manually operated whiteness fine adjustment means BT for instructing fine adjustment information for the reference whiteness information corresponding to the operation of the selection button 62a is in an unadjusted state in which the reference whiteness information is not finely adjusted as the fine adjustment information. Corresponding information, information for fine adjustment to the whiteness increasing side with respect to the reference whiteness information, and information for fine adjustment to the whiteness decreasing side with respect to the reference whiteness information can be commanded.

  In addition, the whiteness fine adjustment means BT can command a plurality of pieces of information corresponding to a plurality of fine adjustment amounts as information for fine adjustment to the whiteness increase side with respect to the reference whiteness information, and the reference As information for fine adjustment to the whiteness decrease side rather than the whiteness information, a plurality of information corresponding to a plurality of steps of fine adjustment amounts can be commanded, and further, the whiteness increase side can be finer than the reference whiteness information. The information for fine adjustment to the whiteness decreasing side rather than the reference whiteness information is configured to command a larger fine adjustment amount than the reference whiteness information.

Next, a specific configuration of the whiteness fine adjustment unit BT will be described.
As shown in FIG. 6, the whiteness fine adjustment means BT displays the fine adjustment information based on the operation panel 69 for fine adjustment for the user to manually operate and the operation state of the operation panel 69. The operation panel 69 for fine adjustment is obtained in the vicinity of the take-out hopper 19, that is, above the take-out hopper 19, as shown in FIG. The partition wall 1 on the side is provided at a location where the user can easily operate the wall surface on the cabin 3 side.

  As shown in FIG. 6, the fine adjustment operation panel unit 69 includes a rotary switch 66 operated by a manually operated rotary knob 65 and a display unit 68 including a plurality of display lamps 67 for displaying a fine adjustment state. The display unit 68 is provided with a total of nine display lamps 67 arranged on the outer peripheral side of the rotary knob 65 at appropriate intervals in the circumferential direction, and any one of them is provided. It is configured to display the current fine adjustment information when lit.

  The fine adjustment processing unit 200 is configured by using the control unit 64. The fine adjustment processing unit 200 includes the rotation operation direction and the rotation of the rotary knob detected based on the detection information of the rotary switch 66. A process for obtaining fine adjustment information from the operation amount and instructing the operation control means 100 and a process for controlling the operation of the display unit 68 so as to be in a display state corresponding to the fine adjustment information are executed.

  In other words, when the new user starts using the equipment, the fine adjustment processing unit 200 always supports the non-adjustment state in which the reference whiteness information is not finely adjusted as the fine adjustment information. In this case, the display lamp 67 located at the center (± 0) is turned on. Then, when the user rotates the rotary knob 65 in the right direction from the non-adjusted state, the fine adjustment information is instructed to finely adjust the whiteness higher than the reference whiteness information. Is rotated in the left direction, the fine adjustment information is instructed to finely adjust the whiteness reduction side of the reference whiteness information.

  In other words, when it is detected that the rotary knob 65 has been operated to the right by a unit amount from the state in which the information corresponding to the non-adjustment state is commanded, the whiteness of the processing target rice increases on the increasing side set unit amount. The fine adjustment information corresponding to the whiteness adjustment information to be performed is commanded, and the display state of the display unit 68 is switched so that the first (+1) right display lamp 67 is lit. Subsequently, every time the rotary knob 65 is operated to the right, the fine adjustment information corresponding to the whiteness adjustment information in which the whiteness increases in increments of the set unit amount up to four steps is commanded, and sequentially adjacent to each other. The display state of the display unit 68 is switched so that the display lamp 67 to be turned on.

  On the other hand, when it is detected that the rotary knob 65 has been operated to the left by a unit amount from the state in which information corresponding to the non-adjustment state is commanded, the whiteness of the processing target rice decreases by the set unit amount on the decreasing side. The fine adjustment information corresponding to the adjustment information is commanded, and the display state of the display unit 68 is switched so that the first (−1) left display lamp 67 is lit. Thereafter, every time the rotary knob 65 is operated to the left, the fine adjustment information corresponding to the whiteness adjustment information in which the whiteness is decreased by the set amount on the decreasing side is commanded up to four steps, and the adjacent adjustments are sequentially performed. The display state of the display unit 68 is switched so that the display lamp 67 to be turned on. The decrease side set unit amount is set to be larger than the increase side set unit amount.

  As described above, a plurality of pieces of information corresponding to a plurality of steps (four steps) of fine adjustment amounts are commanded as information for fine adjustment on each of the whiteness increase side and the decrease side with respect to the reference whiteness information. The information for fine adjustment to the whiteness decrease side instructs a larger fine adjustment amount than the information for fine adjustment to the whiteness increase side.

  Then, when the operation control means 100 outputs the payment information from the coin detector 63 and any one of the whiteness selection buttons 62 is operated to command the whiteness, the operation start condition is satisfied. As an example, the rice milling machine 11 and the opening adjustment motor are adjusted so that the rice milling process is performed by the rice milling machine 11 and the whiteness adjustment state corresponding to the reference whiteness information commanded by the whiteness selection button 62 is adjusted. It is comprised so that the rice-milling operation control process which controls the action | operation of 34 may be performed.

  That is, the operation control means 100 starts driving the rice polishing drive motor 27 and the brown rice supply motor 36 in the rice milling machine 11 in addition to the transfer processing and rice bran discharge processing of the supplied brown rice as the rice polishing operation control processing. Then, the rice milling process is performed by the rice milling machine 11, and the opening adjustment motor 34 is driven to adjust the whiteness adjustment state corresponding to the reference whiteness information. The usable time for performing the rice polishing is set according to the number of coins (100 yen) inserted from the coin insertion slot 61, and automatically when the usable time elapses after the start of the rice milling process. It is configured to stop the rice milling process. By the way, when the consideration is 100 yen, the processing time required to execute the rice milling process of 10 Kg, 20 Kg when the price is 200 Yen, and 30 Kg when the price is 300 Yen is set as the usable time. . However, the absence of brown rice is detected by a brown rice presence / absence sensor (not shown) provided in the rice milling tank 17 until the usable time elapses after the rice milling process is started, and the state is set time. If it continues, the milling process is stopped.

  The operation control means 100 is instructed when reference whiteness information to be finely adjusted by the whiteness fine adjustment means BT is instructed, i.e., when the whiteness selection button 62a for "split" is operated. Is adjusted whiteness information (specifically, as will be described later) obtained based on the reference whiteness information commanded by the whiteness selection button 62 and the fine adjustment information commanded by the whiteness fine adjustment means BT. The rice milling operation control process is executed in such a manner that the opening adjustment motor 34 is adjusted to a whiteness adjustment state corresponding to a target power value).

  In other words, based on the experimental results obtained by actually performing the rice milling process under various conditions for the rice milling, the reference whiteness information instructed by the “sorting” whiteness selection button 62a in advance. A target power value of the rice drive motor 27 capable of obtaining whiteness corresponding to each fine adjustment information is obtained in association with a plurality of fine adjustment information instructed by the whiteness fine adjustment means BT. Fine adjustment information, that is, information corresponding to the non-adjustment state, and information on each of the four levels on the whiteness increasing side and the four levels on the whiteness decreasing side (9 to -4 to +4 information) A plurality of target power values that are stored as map data, and when executing the actual rice milling process, a target power value corresponding to the commanded adjustment state is obtained from the map data, and is measured and measured. 27 power value is the target power value It is to adjust the degree of opening adjustment motor 34 as. Accordingly, the difference between the target power value of any fine adjustment information in the map data and the target power value corresponding to the reference whiteness information corresponds to the fine adjustment amount corresponding to the fine adjustment information.

The whiteness fine adjustment means BT is configured to correct the fine adjustment amount corresponding to the fine adjustment information based on the season information.
Specifically, the map data is prepared with a plurality of map data with different target power values even if the same fine adjustment information is commanded according to the difference in season. The target power value of the rice drive motor 27 is determined using any one of a plurality of map data depending on the situation. In other words, as shown in FIG. 8, a plurality of map data having standard values corresponding to spring (March to May) and autumn (September to November), summer (June to August) ) And a value corresponding to the winter season (December to February). In the example shown in FIG. 8, the target power value corresponding to the reference whiteness information commanded by the four whiteness selection buttons 62 uses the same value in any season.

  In other words, when rice milling is performed in the summer, the rice to be treated has a relatively high moisture content and is relatively soft, and tends to be shaved during the rice milling process. In some cases, the rice to be treated has a low moisture content and is relatively hard, and tends to be difficult to scrape in the rice milling process. When the information is commanded, the fine adjustment amount determined by the experimental result or the like is set so that the rice after the milling process has the same or substantially the same whiteness.

  As a configuration for determining the season, the control unit 64 has a calendar function and can determine which season is currently in accordance with the passage of time, and according to the determination result of the season As described above, appropriate map data among a plurality of types of map data stored in advance is used. With such a configuration, the fine adjustment amount corresponding to the fine adjustment information is corrected based on the season information.

  Further, the operation control means 100 instructs the whiteness fine adjustment means BT to provide information corresponding to the non-adjustment state when the reset discrimination condition set as a condition for resetting the whiteness fine adjustment means BT is satisfied. A reset process for returning to a state to be performed, when the usable time set corresponding to the consideration has elapsed, and when the non-existence state of the user is detected by the human body presence sensor 80, It is configured to determine that the reset determination condition is satisfied.

The adjustment of the whiteness adjustment state in the rice mill 11 will be described.
A load is applied to the rice polishing drive motor 27 that drives the rice milling roll 24 in accordance with the internal pressure of the rice milling chamber 28, and the electric power value changes as the load changes. The change in the load of the rice milling chamber 28 corresponds to the change in the whiteness adjustment state when performing the rice polishing. Therefore, a wattmeter 71 (see FIG. 6) for measuring the actual electric energy of the rice milling drive motor 27 is provided, and the load is detected as a predetermined load while detecting the load of the milling roll 24 from the output information of the wattmeter 71. In other words, the urging force of the urging spring 38 is changed by operating the opening adjustment motor 34 so that the electric energy of the rice drive motor 27 becomes the target electric power value. The whiteness adjustment state is adjusted so that the whiteness of rice is obtained.

Hereinafter, the rice milling operation control process by the control unit 64 will be described based on a flowchart.
As shown in FIG. 7, when the compensation payment information is output from the coin detector 63 and any whiteness selection button 62 is operated and the reference whiteness information is commanded, The driving of the brown rice supply motor 36 is started, and the rice milling process is started by the rice milling machine 11 (steps 1, 2, and 3). When the whiteness selection button 62a for “split” is operated, if the fine adjustment operation is performed by operating the rotary knob 65 in the whiteness fine adjustment means BT, the white balance selection button 62a is operated based on the detection information of the rotary switch 66. The display state of the display unit 68 is switched so as to display fine adjustment information corresponding to the operation state (steps 4, 5, 6). When the rotary knob 65 is operated to perform a fine adjustment operation, fine adjustment information corresponding to the operation state is obtained as fine adjustment information to be commanded. If no fine adjustment operation is performed, the fine adjustment information is currently set. Fine adjustment information is obtained as fine adjustment information to be commanded (step 7). Then, as described above, the season at that time is determined from the measurement result of the calendar function and the elapsed state of time, and appropriate map data is selected. Based on the map data, the target power of the rice drive motor 27 is determined. A value is obtained (step 8), and the opening adjustment motor 34 is controlled so that the actual power value of the rice drive motor 27 measured by the wattmeter 71 becomes the target power value (step 9).

  When the whiteness selection button 62 other than the “percentage” whiteness selection button 62a is operated, the target power value is obtained from the reference whiteness information corresponding to the operated whiteness selection button 62 (step 10). ) The opening adjustment motor 34 is controlled so that the actual power value of the rice milling drive motor 27 measured by the wattmeter 71 becomes the target power value (step 9).

  When the available time set according to the paid consideration, that is, the number of inserted coins has elapsed since the start of the rice milling process, the rice milling process is stopped (steps 11 and 12). Although not shown in the figure, the absence of brown rice is detected by the brown rice presence / absence sensor provided in the rice milling tank 17 until the usable time elapses after the rice milling process is started. If the existence state continues for a set time, the milling process is stopped.

  Then, when the usable time elapses or the non-existing state of the brown rice in the rice milling tank 17 continues for a set time, the rice milling process is stopped, and when the human body presence sensor 80 detects the non-existing state of the user, A reset process for returning to a state in which information corresponding to the non-adjustment state is commanded as fine adjustment information is executed assuming that the reset discrimination condition defined as a condition for resetting the whiteness fine adjustment means BT is satisfied. (Steps 13 and 14). At this time, the display unit 68 is switched to a display state corresponding to the non-adjustment state, that is, a display state in which the display lamp 67 located at the center (± 0) is lit. If the coin insertion is performed after the rice milling process is stopped and the human body presence / absence sensor 80 does not detect the non-existing state, the process proceeds to step 2 and the rice milling process is executed again in the same processing state (step). 15).

[Another embodiment]
(1) In the above embodiment, the whiteness fine adjustment means BT detects the operation state of the rotary switch 66 and commands the fine adjustment information, and the display lamps 67 are arranged in an arc. Instead of such a configuration, the following configuration may be used.

  For example, as shown in FIG. 10, an increase switch 75 that increases the whiteness step by step from the current fine adjustment information by pressing, and the whiteness step by step from the current fine adjustment information by pressing. A reduction switch 76 may be provided, or the display lamps 67 of the display unit 68 may be arranged in a line in the horizontal direction instead of an arc.

  As the configuration of the display unit, fine adjustment information may be displayed by a moving needle type display device or the like instead of a plurality of display lamps.

  Instead of providing a single rotary knob and rotary switch, it is equipped with a plurality of operation switches corresponding to each of a plurality of fine adjustment amounts, and by operating one of the operation switches, It is good also as a structure which commands the said fine adjustment information of the corresponding fine adjustment amount to the said operation control means.

Further, as a configuration that enables the whiteness fine adjustment means to be reset, the following configuration may be used.
That is, in place of the rotary knob and the rotary switch, the fine adjustment processing in the above embodiment can be performed with information on fine adjustment amounts that can be rotated in the forward and reverse directions from the neutral position and that are different in a plurality of stages according to the rotation operation amount. The potentiometer may be configured to include a return operation means for forcibly returning the operation position of the potentiometer to the neutral position when the reset process is performed.

  Further, as the whiteness fine adjustment means, it is linked and linked so that the biasing force of the biasing spring 38 in the above embodiment can be changed and adjusted, and can be moved forward and backward from the neutral position and returned to the neutral position. A manually operated operation tool that is biased and an electric operation type holding means that holds the operation tool in either the forward or reverse direction when the operation tool is operated in either the forward or reverse direction. The operation type holding unit may be configured to release the holding state.

(2) In the above embodiment, the whiteness fine adjustment means can command a plurality of pieces of information corresponding to a plurality of fine adjustment amounts as information for fine adjustment to the whiteness increase side with respect to the reference whiteness information. In addition, as information to be finely adjusted to the whiteness reduction side from the reference whiteness information, the information configured to be capable of commanding a plurality of pieces of information corresponding to a plurality of fine adjustment amounts is exemplified. Instead of the configuration, the configuration may be such that the fine adjustment information can be commanded in a form in which the fine adjustment amount is changed steplessly.

(3) In the above-described embodiment, the whiteness fine adjustment means finely adjusts the whiteness decreasing side rather than the reference whiteness information rather than the information that finely adjusts the whiteness increasing side than the reference whiteness information. The information is exemplified to be configured to command a large fine adjustment amount, but instead of such a configuration, for example, a whiteness of 5 minutes is set as the reference whiteness information. The same fine adjustment amount may be commanded on both the whiteness increasing side and the whiteness decreasing side with respect to the reference whiteness information.

(4) In the above embodiment, as the plurality of map data for obtaining the target power value, the target power values corresponding to the plurality of reference whiteness information are exemplified to use the same value in any season. For example, as shown in FIG. 11, those corresponding to the spring season (March to May) and autumn season (September to November), those corresponding to the summer season (June to August), as shown in FIG. For each of those corresponding to the winter season (December to February), the target power values corresponding to the plurality of reference whiteness information may be set to different values. By the way, in this embodiment, as in the above embodiment, the same or substantially the same white when the same fine adjustment information is commanded in advance according to the experimental result or the like according to the difference in the state of rice that changes according to the difference in season. A value obtained in advance so as to be a degree is set as a target power value corresponding to the plurality of reference whiteness information.

(5) In the above embodiment, the whiteness fine adjustment unit is exemplified to be configured to correct the fine adjustment information based on the season information, but instead of such a configuration, the processing target rice The fine adjustment information may be corrected based on the temperature information.

That is, a grain temperature sensor for detecting the rice temperature is provided at a place where the processing target rice such as the input hopper 8 or the rice milling tank 17 in the above embodiment is temporarily stored, and based on detection information of the grain temperature sensor. For example, if the temperature is a high temperature corresponding to the summer temperature, the information corresponding to the summer map data in the above embodiment is used, and if the temperature is a low temperature corresponding to the winter temperature, the above embodiment is used. It is good also as a structure which uses the information corresponding to map data in winter.
Further, instead of using information corresponding to the map data in this way, information on the difference between the detected value of the grain temperature and a preset reference value, or the outside air temperature and a preset reference outside air temperature Calculating a correction amount for correcting the reference whiteness information commanded by the whiteness setting means from the difference information and the like, and correcting the reference whiteness information by the correction amount You may make it perform.

(6) In the above embodiment, the operation control means adjusts the whiteness based on the reference whiteness information commanded by the whiteness setting means and the fine adjustment information commanded by the whiteness fine adjustment means. The configuration for obtaining the target power value as information is determined based on the map data. However, the configuration is not limited to such a configuration, but only a plurality of reference whiteness information corresponding to the command content of the whiteness setting means is obtained in advance. The information of the correction amount for increasing / decreasing the reference whiteness information is input as the fine adjustment information commanded by the whiteness fine adjustment unit, and is commanded by the whiteness setting unit. The reference whiteness information may be calculated to be increased / decreased by a correction amount commanded by the whiteness fine adjustment means to obtain a target power value as adjusted whiteness information.

(7) In the above embodiment, as the determination criterion for resetting, the usable time set corresponding to the consideration paid by the user has elapsed, or the non-existence state of the brown rice in the polished rice tank has continued for the set time Then, the rice milling process is stopped, and when the human body presence detection means detects the non-existing state, it is configured to determine that the determination criterion for reset is satisfied. Instead of such a configuration, for example, Without detecting the non-existing state of brown rice in the rice milling tank, the usable time set according to the consideration paid by the user has passed, and the human body presence detection means detects the non-existing state Then, it is configured to determine that the reset determination condition is satisfied, or when the usable time set corresponding to the price has elapsed, the reset determination condition Various conditions can be set, such as a configuration for determining that the reset target condition has been satisfied after the set time has elapsed since there is no processing target rice in the milled rice tank. In short, what is necessary is just to determine that the milling process for the processing target rice introduced by the user is finished and the use of the equipment by the user is finished. Is possible.

(8) In the above-described embodiment, the whiteness fine adjustment can be performed when the whiteness selection button 62a of “percentage” among the plurality of whiteness selection buttons 62 is operated. It may be configured such that the whiteness can be finely adjusted even when the whiteness selection button 62 other than the whiteness selection button 62a is operated.

(9) In the above-described embodiment, the coin is inserted as the payment of the compensation for the use of the equipment. However, the payment is not limited to the coin, and the bill is paid, or the prepaid magnetic card or the contactless IC is used. It is possible to apply a form of paying the value by various methods such as payment by card.

(10) In the above embodiment, as the rice milling means, a vertical rice milling machine that performs the rice milling process while the rice mill roll rotates around the vertical axis and moves the processing target rice along the vertical direction is exemplified. However, a horizontal axis type rice milling machine that performs the rice milling process while rotating the rice to be treated along the horizontal direction by rotating the rice mill roll around the horizontal axis may be used.

(11) In the above-described embodiment, the operation control unit 100 adjusts based on the reference whiteness information commanded by the whiteness setting unit and the fine adjustment information commanded by the whiteness fine adjustment unit. As whiteness information, a target power value of the rice polishing drive motor 27 is obtained, and the opening degree adjusting motor 34 as whiteness adjusting means is set so that the actual power value of the rice polishing drive motor 27 becomes the target power value. However, instead of such a configuration, a target value of the pressure applied to the opening degree regulating member 32 is obtained as the adjusted whiteness information, and the detected value of the actually applied pressure becomes the target value. Various configurations such as a configuration for controlling the opening adjustment motor 34 can be applied.

(12) In the above-described embodiment, the case where the processing target rice is brown rice has been described. However, the present invention is not limited to this, and the milled rice processing is provided with a rice huller and the processing target rice introduced into the inlet is rice bran.
