[0021]
FIG. 3 shows a known roll gap adjusting means 39 for opening and closing the roll gap of the hulling rolls 7 and 7. The lower end portion of the arm 29 is pivotally supported by the hulling machine body 31 so as to be able to rotate in the front-rear direction. It is the structure which can adjust the auxiliary hulling roll 7b to a perspective direction with respect to the main hulling roll 7a by screw-fitting to the upper end part of this, and rotating the roll gap | interval adjustment rod 30 forward and backward.
[0022]
A support cylinder 32 is provided on the front side portion of the hulling machine body 31 so as to protrude, a vertical gear case 34 is attached to an end of the support cylinder 32, and a roll screw tube 33 is rotatably fitted and supported on the support cylinder 32. The The gear case 34 is provided with a gear 36 driven by a roll gap adjusting motor 35 and a gear 37 attached to the roll screw 33 in mesh. Thus, the roll screw tube 33 can be rotated forward and backward via the gears 36 and 37 by rotating the roll gap adjusting motor 35 forward and backward. Further, a roll gap adjusting rod 30 is pivoted at the center of the support cylinder 32, and a base portion of the roll gap adjusting rod 30 is engaged with the roll screw tube 33 so as to rotate. Is screwed to the end of the arm 29 supporting the auxiliary hull roll 7b.
[0023]
Thus, when the roll gap adjusting motor 35 rotates in the forward / reverse direction, the arm 29 moves in the perspective direction about the support shaft 29b via the gear 36, the gear 37, the roll screw tube 33, the roll gap adjusting shaft 30, and the screwing piece 29a. And the auxiliary hull roll 7b is moved far and near with respect to the main hull roll 7a, and the gap between the two is adjusted. An adjustment handle 38 is attached to the gear 37. Therefore, when the adjustment handle 38 is manually operated, the roll gap adjusting rod 30 is rotated via the gear 37 and the roll screw 33 to adjust the roll gap between the main hull roll 7a and the auxiliary hull roll 7b. it can.
[0024]
Another embodiment of the roll gap adjusting means 39 will be described with reference to FIGS. A roll screw tube 33 is rotatably fitted and supported on a support cylinder 32, a gear case 34 is fixed to an end of the roll screw tube 33, and a gear 37 attached to the roll screw tube 33 and a roll gap are adjusted in the gear case 34. A gear 36 rotated by a motor 35 is provided in a meshed state. Thus, when the roll gap adjusting motor 35 is rotated in the forward and reverse directions, the arm 29 is rotated in the perspective direction via the gear 36, the gear 37, the roll screw 33, and the roll gap adjusting rod 30, and is moved to the main hull roll 7a. On the other hand, the auxiliary hulling roll 7b is adjusted to be opened and closed.
[0025]
Then, a locking device 40 composed of a ball, a spring and a recess is provided between the support tube 32 and the roll screw tube 33, and the gear case 34 is rotated upward as shown in FIGS. It can be locked in a state (solid line in FIG. 6), or can be locked in a state where the gear case 34 is rotated downward (same phantom line).
[0026]
Therefore, when the adjustment handle 38 is not operated, if the gear case 34 is locked in the upwardly rotated state, the space in front of the operation unit formed on the side of the machine frame can be widened and the periphery of the hulling unit 1 can be increased. The roll gap adjusting means 39 does not get in the way during maintenance. Also, when manually adjusting the roll gap of the hulling roll, if the gear case 34 is locked in a state where it is rotated downward, the adjustment handle 38 can be moved to the state where it is pulled out to the front of the operation unit. The operator can easily operate the adjustment handle 38 positioned in front of the operator and can easily perform maintenance such as replacement of the hulling roll.
[0027]
In this embodiment, with respect to the configuration shown in FIG. 3, by providing the adjustment handle 38 on the inner side and the roll gap adjustment motor 35 on the outer side, the position of the gear case 34 can be brought closer to the side of the hulling chamber 8 and is not bulky. In addition to the configuration, maintenance such as replacement of the hulling roll can be facilitated at the position pulled out before the operation unit as described above during operation. Further, since the operation of the adjustment handle 38 is not obstructed by the dust removal cylinder 14 as in the configuration of FIG. 3, the adjustment side 38 is adjusted while being in a position to operate another operation unit on the operation side (one side of the machine body). Can be operated.
[0028]
Further, the gear case 34 attached to the roll screw 33 is fixed to the support cylinder 32 with bolts in a state of being aligned in the left-right direction (vertical direction in FIG. 7), and the adjustment handle 38 attached to the gear 36 is centered in the front-rear direction of the airframe. It is good also as a structure arrange | positioned in a fixed state so that it may be located in the operation side of the heel hopper 6 from a line. With this configuration, the adjustment handle 38 can be operated easily.
[0029]
Next, another embodiment of the distribution case 17 that distributes and supplies the grains to the swing sorting plates 15 will be described with reference to FIGS. The distribution case 17 attached to the supply part of the oscillating sorting plates 15,... Is divided by the distribution partition plates 41, etc. so as to form the number of distribution channels corresponding to the number of the oscillating sorting plates 15,. .. Are formed on the end surfaces of the partition plates 41,... And filled with a sealing agent 42 such as silicon so as to rise from the end surfaces.
[0030]
The manufacturing method will be described with reference to FIG. As shown in FIG. 9 (1), the convex material 44 is press-fitted into the concave material 43 to mold the distribution case 17, and then the convex material 44 is pulled out from the concave material 43 as shown in FIG. 9 (2). 9 (3), instead of the convex member 44, a sealant-filling mold material 45 is disposed opposite to the concave mold material 43, and silicon or the like is provided in the grooves 41a, 41a ... of the distribution partition plates 41, 41 ... of the distribution case 17. Are filled with the sealant 42, and the sealant-filling mold material 45 is lowered and lowered to fill the grooves 41a of the distribution partition plates 41,.
[0031]
Since it did as mentioned above, the sealing property of the distribution case 17 can be improved, aiming at efficiency of manufacture.
As shown in FIG. 10, a load current sensor 48 for detecting a load current value of the main motor 47 for driving the huller and a hail supply control valve 49 of the hull hopper 6 are provided on the input side of the control unit 46 incorporating the CPU.調節 Supply control valve opening sensor 50, power on / off switch 51, operation / stop switch 52, roll gap opening adjustment switch 53, roll gap closing adjustment switch 54, automatic / manual changeover switch 55, display A changeover switch 56 is connected.
[0032]
The output side of the control unit 46 is connected to a roll gap adjusting motor 35, a main motor 47 for driving the hulling sorter, and a display unit 57 via an output interface (not shown) and a drive circuit. ing.
Next, the control content of the control part 46 is demonstrated.
[0033]
When the power on / off switch 51 is turned on, the control unit 46 is energized and control is started. Whether the operation / stop switch 52 is ON or OFF is detected. When the operation / stop switch 52 is ON, the hulling roll 7 , 7 is executed.
[0034]
The initial gap setting control of the hulling roll is executed as follows, for example. First, when the roll gap is adjusted to open and the load current value detected by the load current sensor 48 does not change, it is determined that the hulling rolls 7 and 7 are not in contact with each other, and the opening adjustment is stopped. When the load current sensor 48 detects an increase in the load current value, the close adjustment is stopped by determining the fine contact of the hulling rolls 7 and 7, and then the roll gap is adjusted to open for a predetermined time. Adjustment is set to a predetermined initial gap (for example, 0.8 mm).
[0035]
When the roll gap initial setting control is completed, an automatic roll gap control operation is then performed. When shifting to this control, the process shifts to a work stabilization waiting process for a predetermined time (for example, 5 minutes), during which the roll gap opening / closing control is stopped, and the roll gap is fixed and the hulling work is performed. Then, when the work stabilization waiting process is completed, roll gap automatic control for adjusting the roll gap to a predetermined gap is performed every predetermined time.
[0036]
Next, another roll gap control device for the hulling roll will be described with reference to FIGS. 11 and 12.
As shown in the flow of FIG. 11, when the operation / stop switch 52 is ON (S01), it is determined whether or not the source power on / off switch 51 has been turned off (S02). Since the determination of the presence / absence of the turn-off operation is regarded as the determination of the presence / absence of the reset state, the main power on / off switch 51 is turned on when the main power on / off switch 51 is in the off state and the operation / stop switch 52 is turned on. In this case, it is determined that the initial hulling work is started. Thus, the roll gap of the hulling roll is adjusted to close (S03), and when the load current sensor 48 detects an increase in the load current value and determines that the fine movement of the hulling roll is detected, the standard 6 sec roll gap is adjusted to open. Adjustment is set to the standard initial roll gap (S04). Next, the operation shifts to an automatic roll gap control operation, and roll gap automatic control is performed to adjust the roll gap to be closed every predetermined time (for example, 12 minutes) (S05). When the operation / stop switch 52 is turned OFF (S05) and the rotation of the hulling roll is stopped, the roll gap control is stopped.
[0037]
Further, when the operation / stop switch 52 is ON and the original power on / off switch 51 is ON and not reset, it is determined that the operation is restarted after the initial hulling operation is stopped. Accordingly, the roll gap of the hulling roll is adjusted to be closed (S07), and the roll gap closing adjustment time until the load current sensor 48 determines the fine contact of the hulling roll to detect an increase in the load current value is measured. It is determined whether or not the roll gap closing adjustment time is a standard time (for example, 6 sec ± α) (S08). If it is the standard time (6 sec ± α), the roll gap of the hulling roll is adjusted to the standard initial roll gap (for example, 0.8 mm) by adjusting the opening gap for a standard time of 6 seconds (S09), and thereafter Performs an automatic roll gap control operation for closing the roll gap for a predetermined gap every predetermined time (for example, 12 minutes) (S05).
[0038]
If the roll gap closing adjustment time is not the standard time (6 sec ± α), it is then determined whether or not the roll time is not less than the standard time (6 sec ± α) (S10). If it is, the roll gap is adjusted to a standard time (for example, 6 sec) and adjusted to a standard initial roll gap (for example, 0.8 mm) (S11), and then the roll gap is set every predetermined time (for example, 10 minutes). An automatic roll gap control operation for adjusting the predetermined gap is performed (S12).
[0039]
Further, when the roll gap closing adjustment time is not longer than the standard time (6 sec ± α), the roll gap of the hulling roll is adjusted to the standard initial roll gap (eg, 0.8 mm) by adjusting the roll gap to the standard time (eg, 6 sec). (SX13), and thereafter, an automatic roll gap control operation is performed (S14) in which the roll gap is adjusted to be closed at predetermined intervals (for example, 15 minutes). When the operation / stop switch 52 is turned OFF and the main motor 47 is stopped, the roll gap control is stopped.
[0040]
Note that the roll gap closing adjustment output time may be changed to be longer or shorter instead of the predetermined time.
As described above, when the hulling operation is temporarily stopped and the hulling operation is resumed, the roll gap of the hulling roll is adjusted to the standard initial roll gap, and then the automatic roll gap control operation is performed. Now, the predetermined time for closing the roll gap can be automatically set to be longer or shorter according to the previous work efficiency, and the resumption hulling work will be based on the previous hulling work, and the hulling work will be resumed smoothly. can do.
[0041]
The initial gap setting when resuming work is adjusted to the roll gap at the previous work, and the predetermined time interval for closing and adjusting the roll gap in the subsequent automatic roll gap control operation is automatically set according to the previous work efficiency. You may comprise.
Next, another embodiment of the hulling roll roll gap control will be described with reference to FIG.
[0042]
In the roll gap control of the hulling roll, the automatic roll gap control device that initially sets the initial adjustment of the hulling roll gap and then closes the roll gap every predetermined time when the automatic roll gap control operation is started. When the operator adjusts the roll gap opening adjustment switch 53 and the roll gap closing adjustment switch 54 to change the standard depletion rate during the operation, the switch adjustment operation is stored. When the hulling operation is temporarily suspended and then resumed, the contents of the change in the removal rate are reflected in the roll gap setting after the resumption.
[0043]
This will be described based on the flow of FIG.
When the operation / stop switch 52 is turned ON, the initial adjustment setting of the roll gap of the hulling roll is made as in the above-described embodiment (S101 to S103). Thereafter, the process shifts to an automatic roll gap control operation, and the roll gap is closed and adjusted every predetermined time, and the hulling operation is performed while maintaining a predetermined removal rate. Thus, when the automatic roll gap control operation is started, the number of times the operator operates the roll gap opening adjustment switch 53 and the roll gap closing adjustment switch 54 is detected (S104). Then, at the end of detection when the operation / stop switch 52 is turned OFF, for example, adjustment operation of depow rate increase adjustment: n1 times, depowment rate decrease adjustment: n2 times is detected (S105), and the final depow rate adjustment result Is determined as n1-n2 = n3 (S106). Next, the initial roll gap opening correction time is calculated by a predetermined calculation formula (n3 × time correction coefficient = T1) (S107). Next, it is determined whether or not the initial roll gap opening correction time (T1) is within an appropriate range (S108). If it is within the appropriate range, the initial roll gap opening correction time (T1) is stored in the storage unit of the control unit (S109). When calculating the initial roll gap opening correction time (T1), the adjustment gap is set to be narrow when the removal rate is increased, and the adjustment gap is set to be wider when the removal rate is reduced. Therefore, consideration is given to prevent the removal rate from becoming high, and the initial roll gap during the resuming operation is set wider to prevent damage to the grains.
[0044]
When the operation / stop switch 52 is turned on (S110) and the hulling operation is resumed, the roll gap initial adjustment setting including roll gap opening adjustment, roll gap closing adjustment, and roll gap opening adjustment of the hulling roll is performed. In this case (S101 to S103), if an appropriate initial roll gap opening adjustment correction time is stored (S114), the roll gap is adjusted based on the corrected opening adjustment time, and the initial roll gap is set. The roll gap is adjusted and set according to the previous work. If an appropriate corrected opening adjustment time is not stored (S115), the roll gap initial adjustment setting based on the standard roll gap opening adjustment time is made.
[0045]
Therefore, while the automatic roll gap control is performed while the roll gap of the hulling roll is closed and adjusted every predetermined time, the hulling work is resumed at the roll gap and the removal rate according to the operator's preference when the work is resumed. Thus, the hulling operation can be resumed smoothly while simplifying the operation at the time of resumption.
[0046]
Note that the roll gap opening (decrease rate lowering) adjustment switch 53 and the roll gap closing (depletion rate higher) adjustment switch 54 may be operated as follows. As shown in FIG. 12, the roll gap opening adjustment switch 53 and the roll gap closing adjustment switch 54 are continuously continuously operated during the hulling operation in which the operation / stop switch 52 is ON and the main power ON / OFF switch 51 is ON. Even if the operation is turned on, the adjustment output of a certain length is output only once. Also, when the operation / stop switch 52 is OFF and the hulling operation is interrupted, and the controller is energized, the roll gap opening adjustment switch 53 and the roll gap closing adjustment switch 54 are turned on. When the manual operation is continuously turned ON, the adjustment output can be continuously output.
[0047]
By configuring in this way, it is possible to prevent the roll gap from being largely adjusted during the hulling operation to prevent abrupt removal rate adjustment, and during maintenance work when the operation is interrupted, The roll gap can be adjusted quickly, and the hulling roll can be replaced quickly.
[0048]
Further, the roll gap opening adjustment switch 53 and the roll gap closing adjustment switch 54 may be configured to be operated as follows. As shown in FIG. 15, during the hulling operation in which the operation / stop switch 52 is turned on and the main power on / off switch 51 is turned on after setting the initial gap of the hulling roll, the roll gap opening adjusting switch 53 and the roll Even if the gap closing adjustment switch 54 is continuously turned on manually, a constant length adjustment output is output only once. Even if the roll gap closing adjustment switch 54 is manually operated, it is continuously turned on for a predetermined time. The adjustment output is performed only a predetermined number of times (for example, twice). Further, in the manual operation of the roll gap opening adjustment switch 53, all the continuous ON operations for a predetermined time are adjusted and output without limitation. Therefore, since the adjustment on the side of lowering the deflation rate is made quick and the adjustment on the side of increasing the deflation rate is made slowly, it is possible to perform the hulling operation while preventing damage to the grains.
[0049]
Next, a vertical grain sorter for grain sorting brown rice will be described with reference to FIG.
The vertical grain sorter 58 for sorting brown rice is configured as follows. Brown rice sorting net tube 59 rotating around the vertical axis, waste rice sorting chamber 60 formed on the outer periphery of brown rice sorting net tube 59, and waste connected to one side of the lower end portion of waste rice sorting chamber 60 The rice extraction cylinder 61a, the brown rice milling spiral cylinder 61 that rotates in the opposite direction to the brown rice sorting mesh cylinder 59 around the same axis axis on the inner periphery of the brown rice sorting mesh cylinder 59, and the lower end of the brown rice milling spiral cylinder 61 Brown rice input hopper 62 for supplying brown rice to the section, fine brown rice extraction hopper 65 for taking out the selected brown rice, and rice cake sorting for removing the rice cake from the waste rice sorting chamber 60 through the waste rice extraction cylinder 61a. The apparatus 63, and a basket take-out cylinder 64 for taking out the basket from the basket sorting apparatus 63 are configured.
[0050]
When the brown rice is supplied to the brown rice charging hopper 62, the brown rice is supplied to the lower end portion of the brown rice cereal helix spiral cylinder 61, and the brown rice cereal helix helix 61 is cerealed in the brown rice sorting net cylinder 59. During the cerealing process, the small grain rice is leaked from the brown rice sorting net 59 to the outside waste rice sorting chamber 60 and discharged, and the large grain rice is cerealed to the upper side and taken out from the milled rice extraction hopper 65 to the outside. It is. Also, the waste rice that has dropped to the lower end of the waste rice sorting chamber 60 is sent to the waste rice take-out cylinder 61a by the take-out blade 66, and the rice cake adhering when it is taken out from the waste rice take-out cylinder 61a is separated by the straw sorter 63. Then, the soot is taken out of the machine through the soot take-out cylinder 64.
[0051]
Then, one end of a ground wire 67 is attached to, for example, the milled rice extraction hopper 65 of this vertical grain sorter 58, and a semiconductor 68 having a negative charge is attached to the other end of the ground wire 67. When it is summed, it emits light. Thus, the static electricity generated by the friction of brown rice during grain sorting and the negative charge of the semiconductor 68 are neutralized to prevent electrostatic charging, and dust adheres to the inner surface of the hopper 65 of the vertical grain sorter 58. To prevent. Further, the neutralized state of static electricity can be confirmed by the light emission of the semiconductor 68.
[0052]
It should be noted that a charge detector capable of detecting electrostatic charge is provided along with the connection of the semiconductor 68, and in accordance with the charge detection of the detector, an attached spraying means is operated to spray the antistatic agent on the inner surface of the hopper 65. It may be configured. This configuration is convenient because it prevents static electricity from being charged.
