Description

The present invention relates to a self-testing device used for measuring the weight ratio of rice and wheat grains and scrap grains in joint drying and preparation facilities for grains. It relates to a test device.

Self-testing devices installed in joint drying and preparation facilities for grains are used to hull (dehull) samples of several hundred grams extracted from grains brought into the facility, and then sort and sort the grains rather than sort them. Waste grains with a small diameter are sorted, and the weight of each is measured (see Patent Documents 1 to 4). As a result, the self-verification device calculates the weight ratio of the sieved grains and the waste grains, and certifies the yield of the sieved grains and the like. Rice and wheat are usually tested by such self-testing devices.

On the other hand, the soybean self-testing device sorts out large, medium, small and scrap soybeans brought into the soybean drying facility and measures the weight of each soybean to test the weight ratio. The soybean self-testing device comprises a sorting machine for separating scraps, a sorting machine for separating large, medium and small grain sizes, and a weighing machine (Non-Patent Document 1). The sorting machine has an inclined conveyor structure that utilizes the fact that the rolling direction of soybeans on an inclined belt conveyor is different between scrap grains and sorted grains. As a sorter, there are two types of sorters: a rotary type that separates soybeans by rotating a mesh tube with a predetermined mesh size and whether or not the soybeans can pass through the mesh, and an inclined conveyor type that uses an inclined belt conveyor similar to the sorter. (see Patent Document 5).

It has a transfer mechanism (rodless cylinder) 52b for throwing in and a receiving cylinder 52c into which the discharge chute 70b of the selector 70 is inserted or connected. The movable hopper 52a is arranged below the weighing unit 80 and receives the weighed raw material grains by the weighing unit 80 when the raw material grains are conveyed. Further, when receiving the grain from which the grains have been removed by the selector 70 from the discharge chute 70b of the selector 70, the movable hopper 52c receives the grain from the receiving cylinder 52c.

The rodless cylinder 52 b vertically moves the movable hopper 52 a to the upper portion of the input path switching section 51 to input the raw material grain or the scrap-removed grain after sorting into the input path switching section 51 .

As shown in FIGS. 6(a) and 6(b), the receiving portion (receiving cylinder 52c) is provided with an on-off valve 52d capable of switching between a state of receiving grain from which scraps have been removed and a state of waiting for receiving. , and its drive portion 52e. The operation of the on-off valve 52 d is interlocked with the switching operation of the input path switching valve 54 .

Further, the weighing scale 80 for weighing the raw grains is arranged below the input port 12 into which the user throws in the raw grains and between the position where the movable hopper 52a receives the raw grains.

In addition, a control unit 100 is arranged in the self-certification device 1, receives the operation set in the operation unit 13, operates the huller unit 20, operates the grain sorter 30, and controls the input route switching valve 54 and opening and closing. It controls the operation of the valve 52d and the movable hopper 52a. The control unit 100 incorporates a CPU and a memory, and implements its control operation by software by reading and executing a program stored in advance in the memory. However, this embodiment is not limited to realizing the functions of the control unit 100 by software, and it is also possible to realize part or all of the functions by hardware. For example, the control unit 100 is configured using a custom IC such as an ASIC (Application Specific Integrated Circuit) or a programmable IC such as an FPGA (Field-Programmable Gate Array), and circuit design is performed to realize the control operation. Do it.

The hulling unit 20 includes a pair of hulling rollers 21 and 22. At least one roller (main shaft roller) 21 of the pair of hulling rollers 21 and 22 is detachable from a shaft 23 that rotates the roller 21. Configuration. Here, as shown in FIGS. 4(a) and 4(c), a screw is formed at the tip of the shaft 23, and the flange 21a of the main shaft roller 21 is sandwiched between the retainer 24 and the cup 25, and tightened with the nut 26. , the main shaft roller 21 is detachably fixed to the shaft 23 .

As a result, when inspecting rice (hull), the main shaft roller 21 is fixed to the shaft 23 and rotated together with the roller 22 so that the chaff passes between the main shaft roller 21 and the roller 22 and is threshed. be done.

In addition, the hulling part 20 is provided with an air blower 27, and blows air to the unhusked brown rice to separate the unhulled rice from the hulls.

When the user selects soybeans as the grain to be tested via the operation unit (touch panel) 13, the control unit 100 displays a display prompting the user to remove at least one of the pair of hulling rollers. (or the screen of the touch panel 13).

The grain sorter includes first and second screen tubes 31, 32 and a drive (not shown) that rotates the first and second screen tubes. When the user selects the grain to be tested via the operation unit 13, the control unit designates the mesh width of the first and second net tubes 31 and 32 according to the selected grain, and replaces the net tubes. A display prompting to do so is displayed on the display device (or the screen of the touch panel 13).

For example, when rice is selected by the user, the control unit 100 designates the same predetermined size as the mesh width of the first and second mesh tubes 31 and 32 . On the other hand, when soybeans are selected by the user, the control unit 100 sets the first mesh tube 31 to a mesh tube having a predetermined mesh width, and sets the second mesh tube 32 to a predetermined mesh width smaller than the mesh width of the first mesh tube. The display urges the user to change to a mesh tube with a mesh width of .

Further, the grain sorter 30 is provided with a pre-grain sorting switching section 33 between the grain hulling section 20 and the grain sorting section 20 as shown in FIG. 4(a). By switching the pre-grain sorting switching unit 33 by its driving unit 34, the grain that has passed through the hulling unit 20 is selectively made to reach one or both of the first and second net cylinders 31 and 32, and grains are sorted. can be selected.

Further, the grain sorter 30 is provided with post-grain sorting switching units 35 , 36 and 37 between the scale 40 and the scale 40 . The post-grain sorting switching units 35, 36 and 37 can selectively cause the grain sorted by the first and second mesh tubes 31 and 32 to reach the scale 40 or the movable hopper 52a.

The control unit 100 controls the pre-grain sorting switching unit 33 and the post-grain sorting switching units 35 to 37 to allow the grains that have passed through the hulling unit 20 to reach the first net tube 31, and the first net tube. Large grains that have not passed through 31 are made to reach a scale 40 and weighed. In addition, the medium and small grains that have passed through the first net cylinder 31 are made to reach the movable hopper 52a and conveyed by the rodless cylinders 52b, so that they pass through the hulling section 20 from the first path 53a to the first The second screen tube 32 can be used to sort the particles into small particles and medium particles. Then, the control unit 100 causes the small grain and medium grain grains sorted by the second net tube 32 to reach the scale 40 in order by the post-grain sorting switching unit 36 and weigh them respectively.

In addition, the self-certification device 1 is provided with a conveying section 90 that conveys the grains weighed by the scale 40 to the sample packer. The transport section 90 includes a discharge hopper 90a and a transport mechanism 90b for transporting the discharge hopper 90a.

In addition, the input port 12 is connected to a path 12a that guides the input raw material grains to the scale 80 and a path 12b that branches a part of the raw material grains as storage raw materials and guides them to a standby hopper 12c. The storage raw material guided to the standby hopper 12c is put into the sample packer 60 by the discharge hopper 90a and the transport mechanism 90b, and packed.

7 and 8 and examples of display screens of the touch panel 13 in FIGS. 9 and 10, the operation of each part of the self-testing device 1 during the rice test and the soybean test will be further described.

As shown in the setting screen in FIG. 10(a), the mesh width of the mesh tube suitable for testing rice (non-glutinous rice, glutinous rice), barley, and soybean is set in advance by the user or by default. stored in memory within 100. It is also assumed that the mesh cylinders 31 and 32 having a mesh width suitable for testing rice (non-glutinous rice) are attached to the grain sorter 30 as an initial setting.

The control unit 100 causes the operation panel 13 to display a screen for accepting the type of grain to be tested, as shown in FIG. 9(a). When the user selects rice (non-glutinous rice) on this screen, the operation of each unit is controlled according to the flow of FIG.

First, the control unit 100 displays on the screen of the touch panel 13 a display prompting the user to dry the raw material grain (rice (non-glutinous rice)) in the test dryer, and then instructs the user to input the dried rice from the input port 12 . is displayed (steps 101 and 102). In response to this, if the user puts in dried rice from the inlet 12, part of the rice reaches the scale 80 through the path 12a. Another part of the rice reaches the waiting hopper 103 through the path 12b and becomes a storage raw material. The control section 100 causes the stock material to be discharged from the standby hopper 103 and conveyed by the conveying section 90 (steps 103 to 105). The transport unit 90 puts the storage material into the sample packer 60, and the sample packer packs the storage material (step 106). It should be noted that it is also possible for the user to select to discharge the raw material to be stored from the machine without packing it (step 107).

After causing the weighing device 80 to weigh the rice, the control unit 100 controls the weighing device 80 to dispense it downward (steps 108 to 110). The rice discharged from the scale 80 is received by the movable hopper 52a. The control unit 100 operates the conveying unit 52 to move the movable hopper 52a to the upper part of the input path switching unit 51, and input rice (step 111). At this time, the control unit 100 switches the input path switching valve 54 of the input path switching unit 51 to the side that guides the rice to the first path 53a. As a result, the rice passes through the first path 53a, reaches the hulling section 20, is dehulled by passing between the hulling rollers 21 and 22, and is separated from the chaff by the wind of the blower 27. and reaches the grain sorter 30 (steps 112, 113).

The control unit 100 switches the switching unit 33 to feed the rice into the first and second mesh cylinders 31 and 32 respectively, and rotates the first and second mesh cylinders 31 and 32 . The mesh widths of the first and second mesh tubes 31, 32 are the same, so that the scrap passes through the mesh and the sieved particles remain in the mesh tubes 31, 32 (steps 114, 115).

The control unit 100 switches the switching units 35, 36, 37 to first discharge the waste grains outside the first and second mesh tubes 31, 32 to the scale 40 (steps 116, 118). After causing the weighing device 40 to weigh the scraps, the control unit 100 causes the weighing unit 40 to discharge the scraps and transport the scraps to the sample packer 60 by the transport unit 90 (steps 120 to 123). The sample packer 60 packs the debris (step 124).

Next, the control unit 100 switches the switching units 35, 36, 37 to discharge the sized grains inside the first and second mesh cylinders 31, 32 to the weigher 40 (steps 117, 119). The control unit 100 causes the weighing device 40 to measure the granules, and calculates the granule yield from the weighing result and the raw material weighing result of step 108 (step 126). The calculation result is printed by the printer 14 provided on the front door 11a. After that, the weighing device 40 is caused to dispense the sized grains, and the sized grains are conveyed to the sample packer 60 by the conveying section 90 (steps 127 and 128). The sample packer 60 packs the sized grains (step 129).

As a result, a sample pack 130 in which raw materials to be stored, waste grains, and sorted grains are packed, and a slip printed with the yield of sorted grains can be created as shown in FIG.

Next, when the user selects soybean 2 on the screen of FIG. 9A, the operation of each section is controlled according to the flow of FIG.

First, the control unit 100 shifts to the navigation mode (step 200), displays the screens of FIGS. (a)), removal of the roller 21 (FIG. 9B), and installation of the selector 70 (FIG. 9C). Specifically, the procedure for exchanging the first and second mesh tubes 31 and 32 is displayed on the screen of FIG. Prompt to replace with the one with the specified mesh width. When the user replaces the first and second mesh tubes 31 and 32, the procedure for removing the roller 21 is displayed on the screen of FIG. 9(c) to urge the user to remove it. When the user removes the roller 21, the screen of FIG. 9(d) prompts the user to install the selector 70, insert the hose 56 into the receiving portion 70a, and connect the discharge chute 70b to the receiving cylinder 52c. prompt.

When the sorting machine 70 is installed, after displaying on the screen of the touch panel 13 a display urging the user to dry the raw material grains (soybeans) in the test dryer, the dried soybeans are put in through the inlet 12.例文帳に追加display urging to do so (steps 201 and 202). In response to this, when the user puts in dried soybeans from the inlet 12, some of the soybeans reach the scale 80 through the path 12a. Another part of the soybeans reaches the standby hopper 103 through the path 12b and becomes stock material. The control unit 100 causes the stock material to be discharged from the standby hopper 103, conveyed by the conveying unit 90, put into the sample packer 60, and packed (steps 203 to 206). It should be noted that the user may select to discharge the cartridges to the outside of the machine without packing them (step 207).

After the soybeans are weighed by the weigher 80, the controller 100 causes the soybeans to be discharged downward (steps 208 to 210), and the soybeans enter the movable hopper 52a as shown in FIG. 5(a). The control unit 100 causes the movable hopper 52a to be transported by the transport unit 52 and loaded from the input path switching unit 51 (step 211). At this time, the control unit 100 switches the input path switching valve 54 of the input path switching unit 51 to the side that guides the soybeans to the second path 53b. As a result, the soybeans pass through the second path 53b and the hose 56 and enter the selector 70 as shown in FIG. 5(b). The sorting machine 70 sorts the soybeans into scrap grains and regular grains. The granules reach the receiving cylinder 52c from the discharge chute 70b as shown in FIG. 6(a) (step 212). At this time, the control unit 100 closes the on-off valve 52d, waits for sizing the soybeans in the receiving cylinder 52c, and lowers the movable hopper 52a in the meantime. When the movable hopper 52a descends, the controller 100 opens the on-off valve 52d as shown in FIG. 6(b), and moves the soybean sizing to the movable hopper 52a.

The control unit 100 transports the movable hopper 52a again by the transport unit 52 and causes it to be loaded from the input path switching unit 51 (step 213). At this time, the control unit 100 switches the input path switching valve 54 of the input path switching unit 51 to the side that guides the soybeans to the first path 53a. As a result, the soybeans enter the hulling section 20 through the first path 53a as shown in FIG. 6(c). Since the rollers 21 of the huller 20 have been removed, the soybeans pass through the huller 20 and reach the grain sorter 30 (step 214).

The control unit 100 switches the switching unit 33 to put the soybeans into the first mesh tube 31 and rotate the first mesh tube 31 . Since the mesh width of the first mesh tube 31 is large, medium grains and small grains pass through the mesh, and large grains remain in the mesh pipe 31 (step 214).

The control unit 100 switches the switching units 35, 36, and 37 to first discharge the large grains in the first mesh tube 31 to the scale 40 (step 215). After having the weighing device 40 weigh the large grains, the control unit 100 causes the weighing device 40 to dispense the large grains, and causes the conveying unit 90 to convey the large grains to the sample packer 60 (steps 216 to 219). The sample packer 60 packs the large grains (step 220).

Next, the control unit 100 switches the switching units 35, 36, and 37 to discharge medium grains and small grains outside the first mesh tube 31 to the weighing device 80, pass through the weighing device 80, and pay out the grains. (steps 221 to 223). Medium grains and small grains enter the movable hopper 52 a , and the control section 100 causes the conveying section 52 to convey them again and throws them from the throwing path switching section 51 . At this time, the control unit 100 sets the input path switching valve 54 of the input path switching unit 51 to the side that guides the medium and small particles to the first path 53a. As a result, medium grains and small grains pass through the first path 53a, enter the hulling section 20, pass through the hulling section 20 from which the rollers 21 are removed, and reach the grain sorter 30 (step 224). .

The control unit 100 switches the switching unit 33 to feed the soybeans into the second mesh tube 32 and rotate the second mesh tube 32 . Since the mesh width of the second mesh tube 32 is smaller than that of the first mesh tube 31, the small particles pass through the mesh and the medium particles remain in the mesh tube 32 (step 225).

The control unit 100 switches the switching units 35, 36, and 37 to first dispense the granules outside the second mesh tube 32 to the scale 40 (step 226). After having the weighing device 40 weigh the granules, the control unit 100 causes the granules to be discharged from the weighing device 40 and transported to the sample packer 60 by the transport unit 90 (steps 227 to 230). The sample packer 60 packs the granules (step 231).

Next, the control section 100 switches the switching sections 35, 36 and 37 to discharge the medium grains in the second mesh tube 32 to the weighing machine 40 (step 232). After causing the weighing device 40 to weigh the medium grains, the control section 100 calculates the yield of the medium grains from the weighing result and the raw material weighing result of step 209 (step 235). The calculation result is printed by the printer 14 provided on the front door 11a. After that, the weighing machine 40 is caused to dispense the regulated grains, and the medium grains are conveyed to the sample packer 60 by the conveying section 90 (steps 236 to 127). The sample packer 60 packs the grains (step 238).

As described above, a sample pack 240 in which soybeans sorted into three stages of large grains, medium grains, and small grains and storage raw materials are packed, and a slip printed with a yield value can be prepared. Also, as shown in FIG. 10(b), the test results can be displayed on the screen.

The self-testing device 1 of the present embodiment described above has the same main body size as the conventional self-testing device 1 for rice and wheat, and can test soybeans only by installing and connecting the selector 70. can. Therefore, it is possible to provide a compact self-testing device capable of testing not only rice but also soybeans.

In addition, in the self-testing device of the present embodiment, it is also possible to test wheat by widening the gap between the rollers 21 and 22 of the hulling section 20 . Also, for soybeans, if only the scraps and the sieved grains are to be separated, the gap between the rollers 21 and the rollers 22 can be widened in the same way as for wheat, and the scraps and the sieved grains can be separated by the grain sorter 30. It is possible.
