Abstract

PROBLEM TO BE SOLVED: To solve the problem that the visibility of unhulled rice worsens by the violent movement of the unhulled rice made visible by an illumination lamp caused to flash in synchronization with the rocking period of a rocking sorting-plate and resulting from the difference in the rocking cycle of the rocking sorting-plate and that of the unpolished rice and the unhulled rice moving thereon.SOLUTION: There is disclosed an apparatus for sorting hulled rice. The apparatus including a rocking sorting-plate 1 for receiving and rocking/sorting hulled rice hulled in a hulling device, a sorting/discharging port 2 constituted of a zone A for discharging unpolished rice, a zone B for discharging mixed rice, a zone C for discharging unhulled rice, and the like, disposed along the side part of the rocking sorting-plate 1, and a transparent plate 3 made from a transparent material and attached to the sorting/discharging port 2, for receiving and guiding the mixed rice to flow out, is characterized by causing an illumination lamp 4 transmissively illuminating the transparent plate 3 from below in the upward direction to flash at a shorter cycle relative to the rocking cycle of the rocking sorting-plate 1.

Description

  In the sorting unit of brown rice and mixed rice in the swing sorter of the rice huller, the sorting state between the brown rice and the mixed rice is easily monitored, and the partition adjustment by the partition plate is facilitated.

  A window plate is provided on the upper surface of the sorting case having the swing sorting plate, and a mirror film is provided on the back surface of the window plate so that the opening / closing angle can be adjusted. There is known a technique (see, for example, Patent Document 1) in which an illumination lamp that blinks in synchronization with the lamp is provided.

JP 2001-246274 A (2nd page, 3rd page, FIG. 1).

  In the swinging sorting of the brewed rice by the swinging sorter, the brown rice and rice bran are flowing due to rocking. It is difficult to identify the mixed state.

  Further, the swinging cycle of the swing sorter is different from the swing cycle of brown rice moving on the swing sorter surface and the fir. Therefore, if the illumination lamp is turned on and off in synchronization with the oscillation cycle of the oscillation sorter, the movement of the eyelid that becomes visible due to this lighting becomes intense, and the visibility deteriorates.

  According to the first aspect of the present invention, the brown rice discharge area A and the mixed rice discharge area B are arranged along the side portion of the swing sorting plate 1 that receives and swings out the rice slid out by the rice huller. And a sorting discharge port 2 such as a soot discharge area C, etc. The transparent discharge port 2 is provided with a transparent plate 3 made of a transparent material for receiving and mixing the mixed rice. The illuminating rice sorting apparatus is characterized in that the illumination lamp 4 that transmits light from the side to the top is blinked at a cycle lower than the oscillation cycle of the oscillation sorting panel 1.

  The brewed rice removed by the hulling device is sorted and discharged to the sorting discharge port 2 through the upper surface of the transparent plate 3 while the upper surface of the swinging sorter 1 is being swung and sorted. The swing sorter 1 is formed on an inclined surface, moving the fed rice to the swaying side while sorting the squeezed rice supplied to the brown rice and the slag while moving the sashimi to the swinging side. The brown rice is sorted and discharged to the brown rice discharge area A of the sorting outlet 2, the mixed rice mixed with brown rice and rice bran is sorted to the mixed rice discharge area B, and the rice bran is sorted to the rice straw discharge area C. At this time, when the operator sees these sorting states, the illumination lamp 4 is turned on. When the illumination lamp 4 is turned on, the illumination is transmitted from the lower side to the upper side of the transparent plate 3, and the brown rice and rice bran flowing on the upper surface of the transparent plate 3 to the sorting outlet 2 are irradiated and transmitted from the lower side. At this time, the brown rice easily permeates the transmitted illumination and absorbs and receives a vision as a substantially translucent state, and the rice bran receives a vision as a dark and substantially black state because it is difficult to pass through the transmitted illumination. As a result, the state and position of the brown rice are difficult to see, and only the state of the rice bran can be clearly identified. Therefore, it can be easily determined whether or not the flow boundary position between the brown rice and the mixed rice has already been properly determined.

  For example, when the rocking cycle of the rocking sorter 1 is driven to rock at about 60 HZ, if the rocking cycle of brown rice and rice bran on the surface of the rocking sorter 1 is about 30 HZ, The blinking lighting of the transmissive illumination lamp 4 that passes through the transparent plate 3 is output at this oscillation cycle (about 30 Hz). The wrinkles on the surface of the rocking sorter 1 move at a cycle lower than the rocking cycle of the rocking sorter 1 (about 30 Hz). 3. Recognized when the ridge on the upper surface is stationary.

  The invention according to claim 2 is provided so that the frequency of the illumination lamp (4) can be changed and adjusted. As described above, the oscillating cycle of the soot and the like on the surface of the oscillating sorter 1 is lower than the oscillating cycle of the oscillating sorter 1, so that the transmitted illumination lamp is irradiated from the lower side to the upper side of the transparent plate 3. The frequency of 4 is also set to a low value in accordance with the oscillation cycle of this haze or the like. However, brown rice, rice bran, and the like that flow down on the surface of the rocking sorter 1 are not uniform because they often have different flow rates, varieties, and moisture amounts. For this reason, the visibility is favorably maintained by changing and adjusting so as to obtain the illumination intensity at the optimum lighting frequency according to the change in the amount of straw, the variety, the moisture value, and the like.

  According to the first aspect of the present invention, since the illumination lamp 4 that transmits and illuminates the wrinkles on the upper surface of the transparent plate 3 blinks in synchronization with the wobbling of the wrinkles on the upper surface of the swing sorter 1, the flow of the wrinkles is stopped. It is easy to confirm the distribution of wrinkles on the surface of the rocking sorter 1 and the visibility can be facilitated.

  According to the second aspect of the present invention, in order to change and adjust the frequency of the illumination lamp 4 that transmits and illuminates the rice bran etc. on the upper surface of the transparent plate 3, the oscillation period varies depending on both the brown rice, rice bran, variety, moisture content, etc. Visibility can be maintained satisfactorily by setting the lighting frequency according to.

  Based on the drawing, a multistage number of swing sorting boards 1 are suspended inside a box-shaped sorting frame 7 and swinged by driving a motor. The rocking sorter 1 has a large number of irregularities on the upper surface, is tilted three-dimensionally, and reciprocally rocks with an appropriate vertical tilt angle in the lateral direction with respect to the longitudinal longitudinal direction. A sorting discharge port 2 is formed on the front end side of the swing sorting plate 1 of each stage, and a squeezed rice supply port 8 is provided on the rear end side to be slid out by the hulling device to supply the squeezed rice. The sorting and discharging port 2 at the front end is formed so as to be almost full in the width direction of the swing sorting plate 1, and this sorting and discharging port 2 is formed at the one side end portion across the lateral end of the swing sorting plate 1. It has a form. The sorting outlet 2 for sorting and discharging the mixed rice at the front end comprises a transparent plate 3 formed on the same surface as the front end surface of the uppermost swing sorter 1, and the swing sorter 1 is a form that swings integrally with the unit 1. A partition plate 6 for partitioning the sorting partition position between the brown rice discharge area A and the mixed rice discharge area B is provided at an intermediate portion of the sorting discharge port 2 viewed through the transparent plate 3. The discharge port 2 is set as a soot discharge area C for discharging the selected soot. A discharge port case 9 that covers the outer periphery of the sorting discharge port 2 is provided.

  By oscillating the oscillating sorter 1, the squeezed rice supplied from each squeezed rice supply port 8 oscillates while flowing on the upper side of the oscillating sorter 1 to the front side of the sorter outlet 2. The brown rice is sorted and divided into brown rice with a large specific gravity when moved upward, light rice cake with a specific gravity that floats and flows to the downside, and mixed rice in a mixed state of brown rice and rice bran between them. The mixed rice flows down to the brown rice discharge area A, the mixed rice flows down to the mixed rice discharge area B, and the rice cake flows down to the straw discharge area C to be conveyed to a predetermined rice hull and sorting process. Among them, in order to move and adjust the partition plate 6 to the sorting partition position between the brown rice discharge area A and the mixed rice discharge area B, a handle 10 is provided on the front surface of the discharge port case 9, and the handle 10 is moved in the lateral direction. The sorting partition position between the brown rice and the mixed rice can be determined by adjusting the movement.

  The rice huller is in a form mounted above the sorting frame 7, and the rice crushed from the rice hulled by the rice huller is removed from the rice hulls by wind sorting (mixed brown rice and rice bran). In this case, the rice is supplied from the sliding rice supply port 8 of each swing sorter 1.

  Here, this rocking sorter is a brown rice discharge area A, a mixed rice discharge area along the side part of the rocking sorter 1 which receives and shakes out the brewed rice slid out by the rice huller. B and a sorting discharge port 2 such as a soot discharge area C are formed. In this sorting discharge port 2 part, a transparent plate 3 made of a transparent material and receiving and mixing the mixed rice is provided. An illumination lamp 4 that transmits light from the lower side to the upper side is provided. The brewed rice removed by the hulling device is sorted and discharged to the sorting discharge port 2 through the top surface of the transparent plate 3 while the top surface of the rocking sorter 1 is rocked and sorted. The swing sorter 1 is formed on an inclined surface, moving the fed rice to the swaying side while sorting the squeezed rice to the swaying specific gravity into the brown rice and the slag. The brown rice is sorted and discharged to the brown rice discharge area A of the sorting discharge port 2, the mixed rice mixed with brown rice and rice bran is sorted to the mixed rice discharge area B, and the rice bran is discharged to the discharge area C. At this time, when the operator sees these sorting states, the illumination lamp 4 is turned on. When the illumination lamp 4 is turned on, the illumination is transmitted from the lower side to the upper side of the transparent plate 3, and the brown rice or rice cake that flows to the sorting outlet 2 on the upper surface of the transparent plate 3 is irradiated and transmitted from the lower side. At this time, the brown rice easily permeates the transmitted illumination and absorbs and receives a vision as a substantially translucent state, and the rice bran receives a vision as a dark and substantially black state because it is difficult to pass through the transmitted illumination. As a result, the state and position of the brown rice are difficult to see, and only the state of the rice bran can be clearly identified. Therefore, it can be easily determined whether or not the flow boundary position between the brown rice and the mixed rice has already been properly determined.

  Further, the transparent plate 3 is provided so as to be able to transmit red illumination, or the illumination lamp 4 is provided so that red illumination is possible. As described above, the crushed rice that is oscillated and sorted by the oscillating sorter 1 and flows out to the upper surface of the transparent plate 3 receives the illumination transmitted by the illumination lamp 4 below, but the transparent plate 3 is red. The brown rice is made of a material, or the illumination lamp 4 is red illumination so that the red illumination is transmitted, whereby the brown rice has a good absorbency of the red illumination and maintains the translucent state well. In addition, since the eyelids do not have this red absorptivity, it is difficult to pass through this transmitted illumination, so that it is visually perceived as a dark and substantially black state.

  The illumination lamp 4 is provided with light sources 5 on the brown rice discharge area A side and the rice bran discharge area C side at both ends of the sorting discharge port 2, and the partition plate 6 part of the mixed rice discharge area B between them. Illuminate by lighting toward the side. Illuminated by projecting light from the brown rice discharge area A located on both sides of the sorting discharge port 2 and the light source 5 on the side of the rice bran discharge area C toward the mixed rice discharge area B between them. Since the transmission irradiation is performed from the lower side to the upper side of the plate 3, the emission intensity of the light emitting surface across the both ends in the longitudinal direction of the illumination lamp 4 can be stabilized, and uniform transmission illumination can be performed over the entire length. be able to. Moreover, the brown rice discharge area A side end, the rice bran discharge area C side end, and the like at both ends of the sorting discharge port 2 are positioned on the partition plate 6 so that direct light illumination from the light source 5 is not performed. By concentrating the transparent illumination on the transparent plate 3 at the basin boundary between the brown rice and the mixed rice, it is possible to accurately discriminate the brown rice and rice bran sorting partition positions at this partition plate 6 position.

  Further, the transmitted illumination area P of the transparent plate 3 is set substantially above the adjustment area of the partition plate 6. The transmitted illumination applied from the lower side to the upper side of the transparent plate 3 by the illumination lamp 4 allows the presence or absence of wrinkles flowing on the upper surface of the transparent plate 3 to be discriminated. Is limited to a substantially adjusting area portion of the partition plate 6 necessary for identification, so that sorting and identification can be performed without showing a part of sorting and discharging conditions such as brown rice at both ends of the sorting discharge port 2 and rice bran. Make it easy and accurate.

  The transparent plate 3 is set to a length over an appropriate width region on both the left and right sides around the sorting partition position between the brown rice discharge area A and the mixed rice discharge area B of the sorting discharge port 2. In response to the mixed rice spill, it is set to an appropriate width for dropping to the sorting outlet 2. The transparent plate 3 is provided in such a manner that it projects and extends only to the front edge portion of the swing sorting plate 1 located at the uppermost stage. Without setting in the lower swaying sorter 1, the sorting of each swaying sorter 1 in the lower tier is made by looking at the sorting partition position of brown rice or mixed rice flowing down on the uppermost swaying sorter 1. The state is determined as the same state. Further, the transparent plate 3 can be integrally configured so as to cover the upper side of the illumination lamp 4.

  The illumination lamp 4 has brackets 11 at the left and right lateral ends of the transparent plate 3, and an LED is attached as a light source 5 to the lower side of the bracket 11. By projecting the light toward the surface, transmission illumination is performed from the lower side to the upper side of the transparent plate 3. This illumination lamp 4 is a fluorescent lamp configuration in which the light projecting tubes 12 at both ends of the glass tube 13 are attached with set bolts 14 so as to be fixed to the bracket 11 portion, and illumination is emitted by light projecting on the glass tube 13 by the light source 5. It is configured. The transparent plate 3 is provided so as to cover the upper side of the illumination lamp 4, and brown rice, mixed rice, or the like flowing down from the upper surface of the swing sorter 2 is received by the transparent plate 3 to flow down.

  The brewed rice flowing down the upper surface of the rocking sorter 1 moves the brown rice to the rocking side of the rocking motion and moves the rice bran to the rocking side, and the mixed rice is between the brown rice layer and the rice bran layer. Layers are formed to form sorting lines La and Lb along the boundaries of each sorting layer. The partition plate 6 is positioned in a sorting line La between the brown rice layer and the mixed rice layer, and performs partition sorting of brown rice and rice cake discharged and dropped from the upper surface of the transparent plate 3 to the sorting discharge port 2. The rice is screened so that no koji is mixed in. The partition plate 6 can partition the sorting partition position between the brown rice and the mixed rice by moving and adjusting the handle 10 laterally along the adjustment hole 15 of the discharge port case 9. A transparent cover 16 is formed in the adjustment area of the partition plate 6 of the discharge port case 9 so that the inside of the discharge port can be easily seen through. A sorting cover 17 is provided on the upper portion of the sorting frame 7 so as to cover the upper surface of the swing sorting plate 1 or the upper surface of the sorting discharge port 2. A transparent window 18 is formed so that the operator can see through the uppermost swing sorter 1 and the sorting discharge port 2.

  The transmission illumination by the transparent lamp 4 is more effective when it is red illumination. Brown rice has good red absorptivity, and the appearance of this brown rice becomes difficult to see by transmitting the brown rice. In addition, since wrinkles do not absorb red, the wrinkles appear black and the wrinkles are easily discriminated. FIG. 5 is a graph showing the spectral reflection spectra of rice bran and brown rice. In brown rice and rice bran, the absorbance P of red illumination is the same regardless of whether the illumination wavelength M is the visible light region Ma or the near infrared region Mb. In contrast, when the absorbance P of red illumination by brown rice is high, A and B are large. In order to emit such red illumination, the light source 5 may be a red lamp or an infrared lamp, the transparent plate 3 may be configured in red, or a red film may be formed on the lower or upper surface of the transparent plate 3. By laying or the like, the illumination that transmits through the transparent plate 3 can be made red, and the brown rice or rice cake that flows down the upper surface can be illuminated in red.

  As shown in FIG. 6, the transmitted illumination 4 is a transparent plate 3 using a surface light emitting member 20 made of a transparent glass plate, a resin plate, or the like, and the surface light emitting member 20 from the light source 5 provided at one end is provided. By transmitting light along the direction, transmitted light is emitted from the surface light emitting member 20 to discriminate brown rice or rice bran flowing through the upper surface of the surface light emitting member 20. Reference numeral 21 denotes a holder that covers 5 parts of the light source. Through the transmission illumination by the surface light emitting member 20, the transmission brightness of brown rice, rice bran, etc. can be recorded as a brightness graph G, and the brown rice discharge area A, mixed rice discharge area B, rice bran discharge area C, etc. are detected. Can be selected. In addition, when rice bran C is mixed in this brown rice layer, the brightness is locally lowered G1, so that the mixing of rice bran can be known.

  An illumination lamp 19 is provided in the sorting cover 17 above the swing sorter 1 so that the projected rice on the surface of the shake sorter 1 can be easily seen by reflected illumination. Moreover, it is also possible to employ a structure in which the illumination lamp 19 for reflection illumination and the illumination lamp 4 below the transparent plate 3 at the portion of the sorting discharge port 2 are switched on by a changeover switch 22. When reflection illumination by the illumination lamp 19 is performed during transmission illumination of brown rice or rice bran flowing down the upper surface of the transparent plate 3, the difference in transmitted light amount between rice bran and brown rice is reduced, and the distinguishability of rice bran is lowered. When it is desired to see the entire surface, the illumination lamp 19 is turned on to reflect illumination, and the illumination lamp 4 is turned off to turn off the illumination from below and make it easy to see. Further, when it is desired to see the state of soot mixing on the upper surface of the transparent plate 3, the illumination lamp 4 is turned off to transmit illumination, and the illumination lamp 19 is turned off. As a result, both the illumination lamps 4 and 19 are not turned on at the same time, and appropriate and easy illumination is performed.

  The sorting cover 17 is provided with a transparent window 18, and the discharge port case 9 is provided with a transparent cover 16. The magnifying lens is provided on a part of the transparent window 18 or the transparent cover 16 to adjust the partition plate 6. The partitioning position on the upper surface of the transparent plate 3 can be easily seen. In addition, when the wrinkles on the upper surface of the transparent plate 3 are identified by transmitted illumination, the visibility of the wrinkles tends to be reduced if there is reflected light. For this reason, a magic mirror or a magic mirror film having a magic mirror function is pasted on the transparent window 18 or the transparent cover 16, etc., and only the illumination from the transmitted illumination lamp 4 is transmitted, and the swing sorter It is possible to improve the visibility environment such as 1 upper surface and 2 parts of the sorting discharge port so that the visibility of the bag is not lowered even in a bright environment.

  Further, as the power source of the transmissive illumination lamp 4, an AC power source (for example, a power source for the controller 30) or a DC power source in the controller 30 can be used as a power source (FIG. 8). A hulling machine having a control controller steps down the AC 200 V of the outlet 31 and uses it as a power source for the controller 30. Therefore, since the secondary side AC voltage (DC12V) 32 is used, a power supply substrate for the light emitting device is not necessary, and the cost can be reduced.

9 and 10, reference numeral 26 denotes an oscillating unit, and 27 denotes LED lighting, which constitutes an intermittent lighting circuit 28.
Since the swinging period of the protruding rice on the top surface of the sorter 1 is shorter (for example, approximately 30 Hz) than the swinging period of the peristaltic sorter 1 (for example, 60 HZ), the transparent plate 3 Since the lighting lamp 4 that is lit on the lower side is flashed intermittently with this swinging rice swinging period (30HZ), the protruding rice can be recognized in a state close to rest. It becomes easy to confirm the distribution of wrinkles on the upper surface of the sorter 1. For this reason, the brown rice A is difficult to recognize as translucent, and the cocoon C becomes black and easily recognized, and the sorting partition position of the cocoon is easily recognized.

  In FIG. 11, a lighting frequency changing device 29 is provided in the intermittent lighting circuit 28. Since the oscillating period of the brewed rice varies depending on the amount of brewed rice on the oscillating sorter 1, the variety, the moisture value, etc., the lighting frequency of the transmitted illumination lamp 4 can be changed arbitrarily according to these. Therefore, the visibility of the wrinkles can be maintained well. Further, the lighting time can be changed together with the lighting frequency.
