The storage silo unit 4 includes a plurality of silos 25, 25..., Destinations are specified for each type of product or for each sorting standard such as appearance quality, and are sorted and stored.

  When a carry-out command from the storage silo unit 4 is received, the degranulated particles are removed by the fine-selection unit 5 in the next step, and then transferred to the preparation unit 6 and subjected to predetermined processing. That is, the fine selection unit 5 is provided with a grain sorting cylinder 30 in the form of an indent cylinder, and the degranulated particles mixed in the cocoon are crushed by the indent and collected in a predetermined take-out tub so that the degranulated grains are taken out from the cocoon. It is. The degranulated particles are stored in the degranulated tank 32 via the degranulated elevator 31 and can be appropriately metered out.

  The selection unit 5 includes a selection weighing machine 33, which is supplied to the wind selection unit 35 of the preparation unit 6 via the preparation unit elevator 34 through a selection process and a measurement process. The scrap particles are collected in the defluxing tank 32 and collected.

  The refined rice cake that has passed through the wind selection unit 35 is supplied to a rice hull sorter 37 via a relay elevator 36 and is subjected to pudding sorting, and the crushed brown rice is removed from the crushed brown rice by the grain shape sorting machine 38. It is a configuration. The sized brown rice is supplied to a stone remover 39, subjected to a stone removal and sorting process, and is transferred from the discharge port to the color sorting unit 7 via a two-way switching valve 41 through a stone removal discharge elevator 40.

  The color selection unit 7 has the following configuration. A configuration is adopted in which the first two-way switching valve 41 is supplied to the flow rate adjustment tank 50 of the color selection unit 7 on the exit side of the stone removing machine discharge elevator 40. Below the flow rate adjusting tank 50, two color sorters are provided, one of which is a primary color sorter 51 and the other is a secondary color sorter 52.

  In the color sorters 51 and 52, a vibration feeder 55 is disposed in the upper part of the box 54 having an upper hopper 53, and an inclined guide chute 56 is provided over the feeder 55 discharge end. Is provided with a light emitting unit 57a, a light receiving unit 57b, and the like above and below the grain (brown rice) flow path, and provided with a color sensor 57 for detecting color information on the surface of the grain for each grain. Further, on the downstream side of the color sensor 57, there is provided an ejector 58 that is connected to a compressed air supply source and controls the on-off valve to turn off the flowing grain out of the path. Below the box body, a guide unit 59 that leads to a non-defective product receiving box that receives the non-defective product G, and a sorting unit that receives the colored particles T that have been removed from the path under the action of the ejector 58 are provided in a mountain shape above the guide unit 59. 60 is formed and guided to the colored particle receiving box.

  Each of the color sorters 51 and 52 has a configuration in which a plurality of combinations of the vibration feeder 55, the inclination guide chute 56, the color sensor 57, the ejector 58, and the like are provided side by side to ensure a predetermined processing amount.

  Now, the brown rice taken out from the primary color sorter 51 (hereinafter referred to as “color selection good product”) is taken out to the shipping section 8 via the color selection good product elevator 61 and the shipping tank elevator 62. On the other hand, the colored particles extracted from the primary color sorter 51 by the action of the ejector 58 are supplied to the secondary color sorter 52 via the return elevator 63. In the secondary color sorter 52, the same processing is performed to sort into two ports. The colored particles (color selection waste) ejected from the secondary color sorter 52 by the action of the ejector 58 are collected in a predetermined waste tank 65 via the color selection waste elevator 64.

  The grains taken out by the non-defective product take-out port of the secondary color sorter 52 are reduced to the stone remover discharge elevator 40 and supplied to the flow rate adjusting tank 50 together with new brown rice.

  The shipping unit 8 is configured to sort and store the color-selected products transferred by the shipping tank elevator 62 into two shipping tanks 66 and 67. A flexible container bagging device 68 that handles an amount of about 1 ton is removed below the shipping tank 66 on one side, and a 30 kg individual bag bagging device 69 is placed below the shipping tank 67 on the other side. Each can be shipped in a package as needed.

  In addition to the above-mentioned packaged shipping mode, the shipping unit 8 has a bulk shipping mode. In the illustrated example, the two-way switching valve 70 is passed through the stone-cutter discharge elevator 40 through the two-way switching valve 41. After passing through the weighing machine 71 by the switching operation, it is configured so as to be transported and supplied to a plurality of bulk shipping tanks 72, 72... This rose shipment form does not go through the color selection unit 7 and is often used mainly for the preparation shipment of wheat.

  One of the plurality of rose shipping tanks 72, 72,... Also serves as the waste tank 65 for collecting color selection waste. That is, the color selection waste elevator 64 is connected to a shipment tank 72a, which is one of the rose shipment tanks, via a path 74, and the color selection waste particles transferred by the color selection waste elevator 64 are arranged in a plurality of rows. Is stored in the tank 72a.

The operation of the above example will be described.
The soot received at the facility is roughly selected and weighed by the receiving part 1 and then transferred to the primary storage part 2 of the next process. Here, drying is performed by ventilating the cocoons sorted and put into the storage bins for each type of product, so that a so-called semi-dry state is obtained.

  Next, the drying unit 3 performs a drying process to a predetermined moisture value. The dried soot is stored in the silo 25. The soot in the silo 25 is prepared and shipped according to appropriate demands.

  The cocoon from the silo 25 is first subjected to a selection process to remove mixed degranulated grains, and the preparation unit 6 prepares it. Here, after the desiccation sorting process is performed by the hulling sorter 37, the grain sorting machine 37 sorts the waste grains and the sized grain brown rice by a sorting net set to a predetermined scale. The sized unpolished rice is further passed through a stone remover 39 to remove foreign matters.

  The sized grain brown rice obtained by the above preparation process is supplied to the flow rate adjusting tank 50 through the stone remover discharge elevator 40 and the two-way switching valve 41. The brown rice in the tank 50 is first supplied to the primary color sorter 51 for processing. That is, in the primary color sorter 51, the flow rate is adjusted by the vibration feeder 55 from the hopper 53 and supplied to the tilt guide chute 56. In the inclined guide chute 56, the color sensor 57 detects whether or not it is a colored particle at a position where it flows down in a line and comes off the chute 56. This detection result is input to the control unit outside the figure, and when it is determined that it is a colored particle, the ejector 58 is turned on, the compressed air is ejected in time, and the colored particle is blown out of the normal path, while the color is recognized. The unpolished brown rice flows down as it is as a non-defective product, and reaches the shipping section 8 via the color selection non-defective product elevator 61 and the shipping tank elevator 62.

  On the other hand, the unpolished rice determined and collected as colored grains is for the purpose of re-selecting the color according to the ejection accuracy of the ejector 58 to ensure the selection accuracy. Therefore, the colored particles are supplied to the secondary color sorter 52 via the return elevator 63 and are subjected to another sorting process.

  The color selection waste particles discharged as colored particles by the secondary color sorter 52 are collected in a predetermined shipping tank 72a among the rose shipping tanks 72 via the color selection waste elevator 64. In addition, this stored color selection waste grain will be used for livestock feed etc., and will be carried out suitably.

  As described above, since the color selection waste particles are for collection using the existing rose shipping tank 72, it is not necessary to separately configure the waste tank, and the installation cost can be reduced. In recent years, wheat is the main target grain for rose shipments, while the target grain for color selection processing is mainly straw. Therefore, it can be used effectively by filling the empty state of the rose shipping tank 72 at different times. Will be.

  FIGS. 5 and 6 show another example of the color selection unit. The stone selection machine discharge elevator 40 of the color selection unit 7 ′ has a third two-way between the first and second two-way switching valves 41 and 70. The switching valve 75 is provided, and in addition to the tank 72 a that receives the color selection particles of the bulk shipping tank 72, the switching discharge destination of the two-way switching valve 75 is the tank 72 b of the bulk shipping tank 72. That is, this tank 72b is used as a temporary storage tank 72b for brown rice before color selection, and is substituted for the flow rate adjustment tank 50. Note that the same reference numerals as those in FIG. 1 indicate the same configuration, and the difference from the configuration in FIG. 1 is that, in addition to the above, a relay elevator 76 is configured as a receiving destination from the temporary storage tank 72b. The elevator 76 has a configuration in which the re-sorted particles that are not actuated by the ejector 58 from the secondary color sorter 52 are returned to the primary color sorter 51 so as to reduce costs by increasing the number of functions.

  Moreover, by configuring as described above, by switching the two-way switching valve 77 from the temporary storage tank 72b, it is possible to supply the accepted grain to the color sorter 51 or to switch the wheat grain to be shipped in bulk. . Accordingly, the flow rate adjustment tank 50 of the color selection unit 7 can be omitted, and the cost can be reduced.

  Inside the box 54 of the color sorters 51 and 52, a cylindrical intake cylinder 78 is disposed in the middle of the flight path k of the colored particles blown off by the ejector 58. The intake cylinder 78 is appropriately attached to the side wall with a length extending across the entire width of the box 54. The intake cylinder 78 has a number of downward intake holes 78a, 78a,... And one side connected to a suction fan 79 to form an intake structure. As described above, by arranging the intake cylinder 78 formed with the plurality of intake holes 78a, 78a ... in the flight path k of the colored particles or in the vicinity thereof, the flight path k is likely to generate a lot of dust. This dust can be efficiently removed from the intake holes 78a and the intake cylinder 78 by suction. Therefore, dust can be prevented from accumulating on the color sensor 57 and the ejector 58 provided above the flight path k, thereby extending the life of the apparatus.

  7 to 9 show an improved configuration of the particle shaper 38. Conventionally, as shown in FIG. 1, a plurality of stages of sorting cylinders 38a, 38a,. As a configuration that provides a better-tasting brown rice by classifying the sized grains into multiple stages by dividing the meshes of the sorting nets 38a, 38a ... and connecting them in series. Yes. By the way, it is usual that the scale of the sorting cylinder is appropriately changed and used depending on the pattern and area. However, this replacement work is cumbersome, and if it is unfamiliar, it may not be possible to obtain an appropriate item, so improvement is necessary.

  Therefore, as shown in FIG. 7, the inner and outer double cylinders 80 and 81 are provided, and the outer cylinder 81 is an octagonal cylinder and has a large mesh M. The inner cylinder 80 is divided into four parts, and the inner cylinder 80 is mounted on the drive shaft 82 for each divided piece, and the outer cylinder 81 is integrated with the inner cylinder 80 by a connecting member. Each of the divided cylinder pieces 80a, 80b, 80c, 80d is configured to have a gap S provided so that the front side portion of the forward rotation (clockwise in FIG. 7) overlaps the outside of the immediately preceding divided cylinder piece within an appropriate range L. In addition, each of the divided cylindrical pieces 80a, 80b, 80c, and 80d is formed with a mesh m set smaller than the mesh M.

  A pulley 83 is provided at one end of the drive shaft 82, and is belt-conducted between the pulley 85 of the drive motor 84. The drive motor 84 is provided so that it can be switched between forward and reverse by a switch operation.

  86 is a guide chute that supplies brown rice to the grain shaper 38 ′ having the above-described configuration, and the whole of the brown rice that is supplied by inserting the tip side of the guide chute 86 into the start end side of the inner cylinder 80 is the inner surface of the inner cylinder 80. It is set as the structure supplied to. 87 is a waste particle collection hopper that receives the grains that leak from the mesh of the outer cylinder 81, and 88 is a sized particle collection hopper that receives the grains remaining up to the terminal ends of the inner cylinder 80 and the outer cylinder 81.

  When sorting the brown rice with the grain shaper 38 ′ configured as described above, the sorting standard of the brown rice is set as the mesh M or the mesh m (M> m) is determined. When selecting the mesh m with slightly small grains, the inner cylinder 80 is used as a sorting net, so the drive motor 84 is switched to the forward rotation side (in the direction of arrow A) with a non-illustrated switch for the drive shaft 82 to rotate forward. (FIG. 9 (1)). The brown rice moves to the terminal side while flowing in the slightly inclined inner cylinder 80, and anything smaller than the mesh m in the meantime leaks from the mesh m and reaches the outer cylinder 81. The outer cylinder 81 is formed with a mesh M, and its size is M> m. Therefore, the waste brown rice that leaks into the outer cylinder 81 leaks the mesh of the outer cylinder 81 as it is. Received by the grain recovery hopper 87. On the other hand, the brown rice grains larger than the mesh m remain in the inner cylinder 80 and are discharged from the terminal portion, and are received by the sized particle collection hopper 88. During normal rotation of the inner cylinder 80, the grains in the inner cylinder 80 are unlikely to enter the gap S, and do not overflow from the gap S and reach the outer cylinder 81.

  Next, when selecting the degree M for brown rice sorting, the drive shaft 82 is rotated in the reverse direction so that the outer cylinder 81 can be used as a sorting net. That is, the drive motor 84 is switched in the reverse direction (arrow B direction) with the changeover switch (FIG. 9 (2)). Brown rice is supplied into the inner cylinder 80 in the same manner as described above, but the brown rice supplied to the starting end side as the inner cylinder 80 reverses flows down from the gap S, and all of it enters the outer cylinder 81 on the starting end side. Become. Thereafter, the waste particles sorted out by the mesh M of the outer cylinder 81 and the leakage of the mesh M are collected by the waste particle collection hopper 87, and the sized particles reach the terminal side of the outer cylinder 81 without leaking the mesh M. Is recovered by the sized particle collection hopper 88.

  As described above, it consists of the outer cylinder 81 and the inner cylinder 80, the mesh of the inner cylinder 80 is set smaller than the mesh of the outer cylinder, and the inner cylinder 80 is formed into a cylindrical shape by combining the divided cylinders. By forming a gap S that can not overflow in the normal rotation and overflow in the reverse rotation in an appropriate range in the overlapping portion, and the inner and outer cylinders 80 and 81 are integrally switched to normal rotation and reverse rotation, By switching between forward rotation and reverse rotation, it is possible to correspond to work with different scales. The brown rice supply position and the collecting means do not need to be installed exclusively, and can be shared by the inner cylinder 80 and the outer cylinder 81, and there is an effect that the apparatus is not increased in size.

  FIGS. 10 to 12 show other examples of the preparation unit, which shows a configuration in which a rocking sorter type heterogeneous grain remover 90 is interposed between the hull sorter 37 and the grain sorter 38. is there. The sizing of the hulling sorter 37 is supplied from the final take-out section through the grain sorting elevator 91 to the hopper 92 of the different grain removing machine 90, and is sequentially supplied from the hopper 92 through the feeding section 93 to the surface of the sorting board 94. It is a configuration to be selected. In some cases, residual wheat grains used in the previous use may be mixed in brown rice as the sized grain, and the wheat grains cannot be removed by the rice hull sorter 37, but they are to be removed by the different grain remover 90. What is separated and separated by the different grain sorter 90 as being critical is taken out to the outside as different grains, or in some cases, the sorter of the hull sorter 37 is reduced and switched by the return elevator 95 and re-sorted. Reference numeral 96 denotes a circulating elevator that reduces mixed grains of different grains and sized grains. The sized particles taken out by the different grain sorter 90 as having a low specific gravity are sent to the grain shape sorter 38 via the brown rice elevator 97.

  The specific configuration of the foreign particle remover 90 is as follows. That is, a cube-shaped frame 90a is configured, a swinging selection mechanism 90b is assembled in the frame 90a, and the lower half of the return elevator 95 and the circulation elevator 96 is assembled (FIG. 12). On the other hand, an upper frame 90c into which the hopper 92 is incorporated is formed on the upper part of the frame 90a.

  Since it is the above configuration, it is possible to facilitate on-site assembly by previously setting the swing sorting mechanism 90b and the lower half of the elevator in the frame 90a. That is, the basic attachment can be completed by setting the upper frame 90c and mounting the upper half of the elevator. In addition, since the elevators 93 and 96 are provided, it is not necessary to install them in the vicinity of the hull sorter when expanding in the facility, which is advantageous in terms of layout.

A sample collecting means 140 is connected to the load receiver 105 and is configured to supply the sampled brown rice to the self-inspection machine 141 for the sizing / waste particle ratio test of the self-inspection unit E.
The flexible container 135 is transported by a transport cart 139 while being placed on a pallet 138 and transported to predetermined shelves 176 and 176 by a stacker crane 175. In response to a shipping request, the product is unloaded from a predetermined shelf via a stacker crane 175. The empty pallet 138 remaining after shipment is collected as follows. That is, the flexible container 135 that is unloaded for each pallet 138 to the predetermined unloading position 177 using the stacker crane 175 and the transport carriage 139 is lifted by a hoist or a forklift or the like and moved to a predetermined position in the product shipping area C2. The empty pallet 138 left at the unloading position 177 is collected in the following manner. That is, the pallet stock portion 178 is provided in the vicinity of the carry-out position 177. The pallet stock unit 178 has a table lifter configuration, receives empty pallets remaining in the adjacent unloading position 177 while being lowered step by step by pneumatic supply / discharge to the cylinder mechanism 181 and stacks a predetermined number of steps (for example, six steps). The empty pallet stocked in a predetermined number of stages is returned to the original carry-out position 177 by the extrusion cylinder 179. Then, the multistage pallet 138 is moved to the transport carriage 139. In this configuration, the carriage 139 is returned to the pallet standby unit 136a by reverse transfer. The reduction transfer of the empty pallet is performed by turning on a switch of the operation panel 180 disposed in the vicinity of the pallet stock unit 178. When this switch is pressed, the stacker crane 175 is being transported while the flexible container 135 is being transported by the transport carriage 139. After delivery to the vehicle, the vehicle waits at the empty pallet receiving position of the transport carriage rail 137, interrupts the loading / unloading operation of the flexible container 135, and preferentially transports the empty pallet. Reference numeral 182 denotes a forward / reverse motor as a roller conveyor direction changing means constituting the carry-out position 177, and its operation switch is provided on the operation panel 180, for example.

  In the above-described embodiment, the empty pallets are stacked in multiple stages and returned to the pallet standby unit 136a at once. However, the pallet stock unit 178 may be omitted and the pallet standby unit 136 may be returned to the transport carriage 139 each time.
