Description

Control device of grain preparation equipment

Technical Field

The present invention relates to a control device for grain preparation equipment, which combines a rice hulling section, a winnowing section, a shaking sorting section, and a particle sorting section.

Background

As a grain preparation apparatus in which a rice hulling section, a winnowing section, a shaking sorting section, and a particle sorting section are combined, there is, for example, a grain preparation apparatus described in japanese patent laid-open No. 2005-152684.

The grain preparation facility disclosed in this document is a control mechanism for controlling a rice and wheat preparation facility including a raw material elevator, a hulling and winnowing device, a separator feeding elevator, a shaking and sorting device, and the like, via a touch panel, and has the following functions: a function of displaying an abnormality cause switch on a display surface of the touch panel, a function of displaying an abnormality occurrence and a position thereof of the preparation apparatus on the display surface by emitting light, and a function of displaying character information on a content of the abnormality and a coping method on the display surface when an operator touches the abnormality cause switch in the light-emitting state.

Thus, since the touch panel is used to control the production facilities such as the raw material elevator, the hulling and winnowing device, the classifier feeding elevator, and the shaking and sorting device of the rice and wheat production facility, the monitoring operation unit can be miniaturized, and the actual monitoring, the rich control, and the inputting operation can be performed even in the field near the production facility.

In addition, the following advantages are provided: the occurrence of an abnormality can be recognized by light emission on the touch panel, and details of the abnormality and a coping method can be obtained by character information by a simple operation, so that an operator can quickly eliminate the abnormality without consulting a skilled person, and efficient preparation processing can be performed.

However, since the control means described above does not record history information such as failure information immediately before the occurrence of a failure and maintenance information at the time of replacing a component, it is impossible to know the past abnormality occurrence situation and maintenance situation, it takes time to find the cause of the failure, and the recovery time and repair time of the failure are relatively long.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a control device for a grain preparation facility, which controls the preparation facility by a touch panel, can grasp an operation state at a glance, can grasp a cause of a failure quickly when the failure occurs, and can shorten a recovery time and a repair time of the failure.

The present invention provides a control device for grain preparation equipment, which comprises: a rice threshing section, a winnowing section, a shaking sorting section, a particle sorting section, and a touch panel control section operable to drive and stop the respective sections, the touch panel control section including: a production line flow display function for displaying the normal operation state by lighting when the grain preparation equipment is normally driven; an error display function of displaying the location of an abnormal portion and displaying the repair sequence of the abnormality when the abnormality occurs in the grain preparation facility; and an abnormality history display function that displays a history of past abnormality occurrences when an abnormality occurs in the grain preparation apparatus.

According to this configuration, the touch panel control unit includes: a production line flow display function for displaying the normal operation state by lighting when the grain preparation equipment is normally driven; an error display function of displaying the location of an abnormal portion and displaying the repair sequence of the abnormality when the abnormality occurs in the grain preparation facility; and an abnormality history display function for displaying the history of past abnormality occurrence when abnormality occurs in the grain preparation facility, so that the operation status can be grasped at a glance by the production line flow display function, and the abnormality site and the cause of the abnormality can be rapidly grasped when abnormality occurs, etc. by the error display function, and the content of past abnormality occurrence can be grasped by the abnormality history display function, and recovery time and repair time can be shortened.

For example, if the same abnormality history is reported in the past by referring to the abnormality history display function, the serviceman can think which component is the cause and the normal operation and the abnormal operation are repeated. In addition, the recovery time and repair time can be shortened by replacing the desired part with a new one immediately.

The touch panel control unit may be provided with a component replacement reporting function for setting an endurance time of a consumable component used by each unit of the grain preparation facility in advance and reporting an alarm when the endurance time of the consumable component reaches the set endurance time.

According to the touch panel control unit, since the touch panel control unit has a component replacement notification function for setting the endurance time of the consumable component used by each unit of the grain preparation facility in advance and notifying an alarm when the usage time of the consumable component reaches the set endurance time, the replacement timing of the consumable component is notified in advance, and the operator can operate the device with caution. In addition, the maintenance personnel can easily grasp the maintenance state of the consumable parts, find out the cause of the abnormality and shorten the recovery time and the repair time.

The touch panel control unit may have a traceable history writing function, so that the distribution history of the raw material supplied to the grain preparation facility can be confirmed. According to the touch panel control unit, since the touch panel control unit has a traceable history writing function, it is possible to confirm the distribution history of the raw material supplied to the grain preparation facility, and it is possible to confirm whether the cause of the abnormality is caused by the raw material. For example, if the moisture content of the raw material grain supplied to the grain preparation facility is grasped from the traceable history, the maintenance worker can estimate that the flow resistance of the grain is large due to the excessive moisture content of the raw material grain, and the clogging is likely to occur in the transportation path, which contributes to finding the cause of the abnormality.

The shaking separation section may separate mixed rice subjected to rice husking and air separation by the rice husking section and the air separation section into a rice region, a mixed rice region, and a brown rice region, a separation partition plate may be movably provided at a grain discharge end of the shaking separation section to separate the regions, and when an automatic operation mode provided in the touch panel control section is selected, movement of the separation partition plate may be controlled so as to be accurately positioned in the vicinity of a boundary position of the regions.

Embodiments of the present invention are explained with reference to the drawings. Fig. 1 is a flowchart showing a treatment process of a grain preparation facility of the present invention, fig. 2 is a perspective view showing an appearance of the whole grain preparation facility, and fig. 3 is a front view thereof.

As shown in fig. 1 to 3, the grain preparation apparatus 1 of the present invention has the following parts as main parts: a rice hulling section 2 formed by a pair of rubber rollers; a winnowing part 3 for wind-sorting rice hulls, blighted grains and light impurities from the hulled rice; a shaking separation part 4 for separating the mixed rice after the air separation into paddy, brown rice and mixed rice by shaking separation; a granule sorting section 5 for sorting the sorted brown rice into whole granules having full granules and unripe granules.

The rice hulling section 2 and the winnowing section 3 are arranged in parallel to form an integral structure, and a mixed rice winnower 6 and a mixed rice tank 7 are provided between the winnowing section 3 and the shaking separation section 4 to winnower the mixed rice from the winnowing section 3 to the shaking separation section 4. Further, a brown rice winnower 8 is provided between the shaking and sorting section 4 and the grain sorting section 5 to winnower the brown rice from the shaking and sorting section 4 to the grain sorting section 5. Reference numeral 9 denotes a rice returning winnower for returning sorted rice in the winnowing section 4 and winnowing such as overflowed rice which cannot be husked by the rice husking section 2 to the rice husking section 2, reference numeral 10 denotes a control panel for controlling each section, reference numeral 11 denotes a suction fan for discharging rice husks and foreign matters separated by the winnowing section 3 to the outside of the winnowing section, reference numeral 12 denotes a supply tank for the rice husking section 2, reference numeral 13 (see fig. 1) denotes a return tank for rice to the rice husking section 2, reference numeral 84 denotes a stand for arranging the grain sorting section 5 at a relatively high position, reference numeral 9a denotes a changeover valve for changing over whether to supply the grain which is winnowed by the winnowing section 9 to the supply tank 12 or to discharge the grain to the outside of the winnowing section 2, and reference numeral 8a denotes a changeover valve for changing over whether to supply the grain sorting by the winnowing section 8 to the grain sorting section 5 or to discharge the grain to the outside of the grain.

The control panel 10 is constituted by: a mechanical input unit 10a including basic various switches, and a touch panel display unit 10b that can be touched by a liquid crystal panel. As shown in fig. 4, 4 buttons, that is, an "operation button 14", a "setting button 15", a "tracking button 16", and an "alarm button 17", are substantially set on the touch panel display unit 10 b.

In the operation button 14 of fig. 4, the operation menu of fig. 7 is shifted to by pressing the operation button 14, so that three operation methods of automatic operation, single operation, and remote operation can be selected. That is, if the "automatic operation" 14a (see fig. 7) is selected, the automatic operation is enabled, and if the "individual operation" 14b is selected, the rice threshing section 2, the air separation section 3, the shaking and sorting section 4, the mixed rice winnower 6, the brown rice winnower 8, and the rice returning winnower 9 can be operated individually, and if the "remote operation" 14c is selected, the operation can be enabled by a remote command from an operation room away from the machine.

In the setting button 15 of fig. 4, by pushing the setting button 15 and shifting to the maintenance screen 18 of fig. 5, the duration of each consumable part can be set. Further, if the usage time reaches the endurance time while the grain preparation facility 1 is operating, an alarm may be issued through the pop-up window screen to urge the user to replace the consumable part.

Referring to fig. 5, a durable time setting frame 19 for each consumable part is provided on the maintenance screen 18, and by pressing a numeric key displayed in the setting frame 19, a numeric value of an arbitrary value can be input to the durable time. Further, by pressing the "display only" button 20 provided on the maintenance screen 18, it is possible to confirm whether or not the pop-up display is performed when the set time has elapsed. The initialization button 21 provided on the lower portion of the maintenance screen 18 is a button that can return to a preset standard endurance time. As the standard durability time, the consumption time of the rubber roller was 100 hours, the consumption time of the lubrication oil was 200 hours, the consumption time of the rice husker charging tank was 1000 hours, the consumption time of the particle sorter wire mesh replacement was 1500 hours, and the consumption time of the compressor discharge was set to 50 hours. If the grain preparation apparatus 1 is operated with the endurance time set as described above, the user may be notified with an alarm if the usage time reaches the endurance time.

Next, the tracking button 16 in fig. 4 is pushed to move to the tracking setting screen 22 in fig. 6, whereby various kinds of tracking information can be inputted and recorded. The tracking information is automatically assigned year, month, day, start/end time as one data file on the database, and various conditions and data such as variety, grade, division, cultivation division, color selection, metal mesh size, discharge source, input destination, output amount, yield, sales destination, end user, and water are sequentially input, and the data is registered by pressing the write button 23. The number of data files can be saved to 1000, and if the number exceeds 1000, the data files are overwritten and saved from the old data files. In addition, by pressing the tracking history tag 24, past information can be retrieved. Reference numeral 25 is a page up button, and reference numeral 26 is a page down button, and has a function of enabling page turning.

Next, the automatic operation of the grain preparation facility according to the present embodiment will be described. When the "automatic operation" 14a in fig. 7 is selected, the swing-sorting-machine setting screen 27 (see fig. 8) is started to perform an operation of discharging all grains on the sorting plate of the swing-sorting machine, and then the operation is shifted to the automatic operation screen 28 (see fig. 9). In the automatic operation screen 28, when the preparation for operation is completed, the "preparation completion" button 29 is turned on, so that if the "operation" button 30 is pressed, the operation starts from the particle sorting unit 5 in the subsequent step, and the brown rice winnower 8, the shaking sorting unit 4, the mixed rice winnower 6, the rice returning winnower 9, the winnowing unit 3, and the rice threshing section 2 are started in this order. On the other hand, the "stop" button 31 is for stopping the rice hulling part 2 in the preceding step, and stops the air separation part 3, the rice returning and winnowing machine 9, the mixed rice winnowing machine 6, the shaking and sorting part 4, the brown rice winnowing machine 8, and the grain sorting part 5 in this order. Reference numeral 32 is a "temporary stop" button that puts the entire apparatus 1 into a standby state.

When the "operation" button 30 is pressed to start the automatic operation, the respective parts are adjusted. In fig. 9, if the supply tank sensor button 33 is pressed, the flow proceeds to the tank sensor setting screen 34 (fig. 10). A lower limit sensor 12a (see fig. 1) for detecting a lower limit value of grains is provided in the supply tank 12 of the rice hulling part 2, and the condition setting when the lower limit sensor 12a is operated can be set on the sensor setting screen 34 of fig. 10. That is, in the left column of fig. 10, a rice hulling section activation time setting section 35 (20 seconds as a standard value) for setting a time to immediately activate the rice hulling section 2 when the lower limit sensor 12a is on (i.e., a state in which the raw material is left), and a rice hulling section deactivation time setting section 36 (0.7 seconds as a standard value) for setting a time to immediately deactivate the rice hulling section 2 when the lower limit sensor 12a is off (i.e., a state in which the raw material is not present) are provided.

On the other hand, an upper limit sensor 13a (see fig. 1) for detecting an upper limit value of grain is provided in the return tank 13 of the rice hulling section 2, and the condition setting when the upper limit sensor 13a is operated can be set on the sensor setting screen 34 of fig. 10. That is, in the right column of fig. 10, there are provided a rocking sorting section stop time setting section 37 (2 seconds as a standard value) for setting a time to immediately stop the rocking sorting section 4 when the upper limit sensor 13a is on (i.e., a state immediately before returning more rice and overflowing from the return tank), a rocking sorting section start time setting section 38 (0.7 seconds as a standard value) for setting a time to immediately start the rocking sorting section 4 when the upper limit sensor 13a is off (i.e., a state where returning less rice is present), and an alarm occurrence time setting section 39 (3 seconds as a standard value) for setting a time to immediately issue an alarm when the upper limit sensor 13a is on (i.e., a state where returning more rice and overflowing from the return tank). The above-described time setting is performed on the sensor setting screen 34.

When the time setting is completed, the rice husking portion button 40 is pushed in fig. 9, and the screen is shifted to a rice husking portion adjustment screen 41 (fig. 11). Here, a hulling ratio is set arbitrarily in the hulling current setting unit 42 and a flow rate setting unit 43 by providing the hulling current setting unit 42 and the flow rate setting unit 43 and pressing the upward and

downward keys

44 and 45, respectively.

In fig. 9, if the rice blending bin sensor button 46 is pressed, the operation proceeds to a rice blending bin sensor setting screen 47 (fig. 12). The rice-mixing tank 7 of the swing sorting section 4 is provided with an upper limit sensor 7a for detecting an upper limit value of grains and a lower limit sensor 7b for detecting a lower limit value of grains (see fig. 1), and conditions for setting the operation of the upper limit sensor 7a can be set on the rice-mixing tank sensor setting screen 47 of fig. 12. That is, in the upper left column of fig. 12, a rice husking section stop time setting unit 48 (3 seconds as a standard value) for setting a time to set whether or not the rice husking section 2 is stopped immediately when the upper limit sensor 7a is on (i.e., a full state in which the mixed rice is staying, i.e., just about to overflow), and a rice husking section restart time setting unit 49 (15 seconds as a standard value) for setting a time to slightly reduce the flow rate until the rice husking section 2 is restarted when the upper limit sensor 7a is off (i.e., a state in which the mixed rice is reduced from the full state) are provided. In addition, in the upper right column of fig. 12, there are provided an oscillating sorting section stop time setting section 50 (standard value: 3.5 seconds) for setting a time to immediately stop the oscillating sorting section 4 when the lower limit sensor 7b is off (that is, when the mixed rice is reduced and the sorting unevenness is generated), and an oscillating sorting section restart time setting section 51 (standard value: 15 seconds) for setting a time to slightly increase the flow rate until the oscillating sorting section 4 is restarted when the lower limit sensor 7b is on (that is, when the mixed rice is retained again and the sorting unevenness is eliminated).

As shown in fig. 1, a vibratory feeder 52 capable of controlling the increase and decrease of the flow rate when the raw material is supplied from the supply tank 12 to the rice hulling section 2 is provided. For example, when an electromagnetic feeder is used, the magnitude of the vibration can be adjusted by current control, and the amount of flow can be adjusted when the raw material is supplied from the supply tank 12 to the rice hulling section 2. A control panel provided with the oscillating feeder 52 in the lower left column of fig. 12 is provided with a feeder flow rate increasing unit 53 (0.2% more than the current) for slightly increasing the flow rate when the lower limit sensor 7b is turned on, and a feeder flow rate reducing unit 54 for slightly reducing the flow rate when the upper limit sensor 7a is turned off (in a state where the mixed rice is reduced from a full state).

When the setting is completed, the swing sorting unit button 55 is pressed in fig. 9, and the screen transitions to the swing sorting machine setting screen 27 (fig. 8). As shown in fig. 1, in the swing sorting section 4, a sorting partition plate 4a for partitioning each of the rice area, the mixed rice area, and the brown rice area is provided at the grain discharge end of the swing sorting plate, and the sorting partition plate 4a is configured to be electrically controllable so that a screw with a gear motor is movably attached in the left-right direction (reference numeral 4a in fig. 8 denotes a partition plate for partitioning the brown rice area and the mixed rice area, and reference numeral 4c denotes a partition plate for partitioning the rice area and the mixed rice area, and the partition plate 4c is also moved by moving the partition plate 4 a). In particular, an optical sensor 4b that can determine the paddy and the brown rice by color is attached to the sorting partition plate 4a (partition plate that partitions the brown rice region and the mixed rice region), and this optical sensor 4b can determine whether the paddy is flowing or the brown rice is flowing near the boundary position, and functions to accurately position the sorting partition plate 4a near the boundary position of the mixed rice region and the brown rice region. In the adjustment screen 27 of fig. 8, adjustment during automatic operation of the sorting partition plate 4a can be performed.

Referring to the setting screen 27 of fig. 8, the divider plate position setting unit 55 is shown in the lower part of the screen 27, and the operator can check whether or not the position of the sorting divider plate 4a is the reference position 56, and can press the right button 57 to move the display of the reference position 56 to the right when the brown rice region is to be enlarged, and can press the left button 58 to move the display of the reference position 56 to the left when the brown rice region is to be reduced. Reference numeral 59 is a determination button for determining the reference position 56 of the sorting

separator

4a, 60 is a pointer indicating the position of the sorting separator 4a at the present time, 61 is a flow rate adjusting unit for adjusting the amount of mixed rice in the

oscillating sorting unit

4, and 62 is an angle adjusting unit for adjusting the angle of the oscillating sorting unit 4.

Next, the automatic operation of the sorting partition plate 4a will be described with reference to fig. 13. Now, as shown in fig. 13A, when the pointer 60 indicating the mounting position of the optical sensor 4b indicates the position of "5", the sorting separation plate 4a is located at a position shifted to the paddy side by "2" more than the reference position "3". At this time, the circulation discharge valve 63 (see fig. 9) of the shaking and sorting unit 4 is switched to the outside of the discharge machine, and the brown rice is discharged. At this time, the gear motor of the sorting partition plate 4a is controlled to move the sorting partition plate 4a in the rice grain direction.

Next, as shown in fig. 13B, the movement of the sorting separator 4a in the rice grain direction is controlled, and when the optical sensor 4B finally senses "rice" and the pointer 60 indicates the vicinity of the position of "6", if this state is reached, the circulation discharge valve 63 (see fig. 9) is switched to the in-machine circulation side, and the sorting separator 4a is controlled to move in the brown rice direction.

As shown in fig. 13C, when the sorting separation plate 4a is moved in the brown rice direction and the optical sensor 4b does not sense "rice", the pointer 60 indicates "5" or less, and if this state is reached, the circulation discharge valve 63 (see fig. 9) is switched to the machine-outside discharge side, and the brown rice discharge state is reached. Then, as shown in fig. 13A, the separation partition plate 4a is controlled to be close to the rice. The position control of the sorting separator 4a as described above is a control for controlling the sorting separator 4a to be near the reference position "3" and for increasing the discharge amount of the brown rice to the outside of the machine as much as possible. At this time, when the movement of the sorting separator 4a is greatly deviated from the reference position 56 and it takes a long time for the movement of the sorting separator 4a to converge to the reference position "3", it is considered that an abnormality occurs during the operation, and the operator can easily estimate whether or not the abnormality occurs by observing the movement of the sorting separator 4 a.

When the above setting is completed, the particle sorting unit button 64 is pressed in fig. 9, and the screen transitions to a particle sorting unit setting screen 65 (fig. 14). In the grain sorting section setting screen 65, the timing of the normal rotation and reverse rotation of the sorting wire netting 5a (see fig. 1) of the grain sorting section 5 may be set in order to prevent rice grains from clogging the mesh of the sorting wire netting 5 a. Reference numeral 66 denotes a normal rotation time setting unit which can set a normal rotation time of the sorting expanded metal 5a, and two hours can be set as a standard value. Reference numeral 67 denotes an inversion time setting unit, which can set an inversion time, and 30 seconds can be set as a standard value. Reference numeral 68 denotes a stop time setting unit which can set a time for stopping the normal rotation of the sorting wire 5a and then starting the reverse rotation of the circulation discharge valve 8a (fig. 1) in a state outside the discharge machine (a state where rice grains are not supplied), and 60 seconds can be set as a standard value.

Next, the single-action operation of the grain preparation facility according to the present embodiment will be described. When the "single action operation" 14b in fig. 7 is selected, the operation proceeds to a single action screen 69 (see fig. 15) and the motors are driven. When starting, the motor is started from the downstream side. First, in order to drive the particle sorting unit 5, the motor 70 of the particle sorting machine is rotated in the normal direction, the motor 71 of the residual discharge valve 8a is switched to the normal state, and the motor 72 of the grain sorting machine 8 is driven. The driving of each motor can be started by pressing a touch button on the one-touch screen 69. Subsequently, the rice threshing section 2, the winnowing section 3, and the shaking and sorting section 4 are driven. The motor 73 of the mixed rice thresher 6 is started, and the swing sorting section 4 switches the valve motor 74 of the circulating discharge valve 63 of the swing sorting section 4 to the circulating position, and after the sorting state on the sorting plate is stabilized, the valve motor is switched to the discharge position. Further, the local motor 75 of the swing sorting unit 4 may be driven after the flow rate of the swing sorting unit 4 and the angle of the sorting plate are appropriately adjusted. The rice husking part 2 and the winnowing part 3 start a rice husk conveying fan motor 76, a motor 77 of the rice returning winnowing machine 9, a motor 78 for a mixed rice discharging screw, and a motor 79 for a winnowing machine in this order, and then start a local motor 80 of the rice husking part 2. By pressing each start button on the one-touch screen 69, the on/off operation of each motor can be performed.

As described above, the operation of the grain preparation facility according to the present embodiment is performed by the automatic operation or the single-action operation selected by the operator, and a method of dealing with the occurrence of an abnormality in the motor or the like will be described below.

In the automatic operation, an automatic operation monitor as shown in fig. 9 is displayed during the operation, and the flow of the entire facility becomes a production line flow display, so that the operation state can be grasped at a glance. In such a normal operation, if an abnormality occurs in the motor or the like, for example, an abnormal portion and an alarm display are displayed as shown in fig. 16. When such screen display is performed, the operator finds the cause and takes a recovery measure. For example, in the case of fig. 16, if the clogging of the grain is simply caused in the mixed rice thresher 6, the grain is removed to remove the clogging, the thermal relay in the power disc 81 (see fig. 2) is restored, and the alarm is released by pressing the alarm release button 82. On the other hand, when the motor 73 of the mixed rice grain thrower 6 is damaged, such as being burned out, the thermal relay of the power disk 81 is restored after the motor 73 is replaced with a new one. At this time, the confirmation of the simple clogging of the mixed rice thresher 6 or the burnout of the motor 73 can be determined to some extent by confirming the alarm screen of fig. 17.

When the alarm release button 82 of fig. 16 is pressed, the process goes to the main menu of fig. 4, and the alarm button 17 is pressed to display a past alarm history list as shown in fig. 17. Referring to fig. 17, it can be known that the mixed rice winnower 6 is clogged many times in the past. If a maintenance person can determine that a part of the motor 73 is burned out based on the history and the operation of temporarily stopping the motor is repeated, the motor 73 can be replaced with a new one as a fundamental solution.

After the maintenance person replaces the motor 72 of the rice mixer 6 with a new one, the operator pushes the alarm release button 83 of fig. 17 to move to the main menu of fig. 4, and can start the operation again. The present invention can be applied to the field of small-sized compact grain preparation equipment such as a small-sized rice center.

The embodiments of the present invention have been described above, but the present invention is not limited to the examples of the above embodiments, and can be implemented in other forms by adding appropriate modifications.
