Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stone removal device for an unmanned rice milling facility.

[Prior art] The machine is equipped with a brown rice input hopper, a rice polishing device, and a device drive unit that can drive these devices by inserting a coin, and a person who wishes to mill brown rice can input brown rice into the input hopper and insert a coin. There is an unmanned rice milling facility that mills rice.

[Problems to be solved by the invention] When milling brown rice in such an unmanned rice milling facility, if stones are mixed in the brown rice, the rice milling equipment etc. may be damaged or stones may be mixed in the polished rice. It becomes necessary to install a stone removal device and add a stone removal process.

If this de-stoning device is installed, after the previous rice milling operation is completed, the brown rice will gradually flow over the top surface of the sloping and vibrating sorting plate of the de-stoning device. , brown rice is distributed almost over the entire upper surface of the sorting plate, and a very small amount of polished rice remains at the end of the polishing roll in the rice polishing device.

In this situation, the rice milling process is carried out by the next person who wants to mill the rice.If the brown rice to be milled is both non-glutinous rice, there is almost no problem even if the white rice before and after it is mixed, but if the rice to be milled later is In the case of glutinous rice, the glutinous rice that is distributed over the entire surface of the top surface of the sorting plate of the destoning device mixes with the glutinous rice that is supplied later for a long time, resulting in glutinous rice in many parts of the glutinous rice. This causes a problem in that the sorting work is virtually impossible. (In addition, non-glutinous rice, which remains in a very small amount at the end of the polishing roll in the rice milling device, is concentrated and taken out at the beginning of milling, so its sorting is relatively easy and there is almost no problem.) Therefore, this invention was developed. When milling mochi rice with an unmanned rice milling device, by providing a de-stoning drive operation means that can drive only the de-stoning device in advance of other devices, the top surface of the sorting plate of the de-stoning device is By removing the distributed brown rice prior to the rice polishing operation, it is possible to prevent non-glutinous rice from being mixed with sticky rice over a wide area, thereby solving the drawbacks of conventional equipment.

[Means for solving the problem] The technical means of the present invention for solving the technical problem is as follows: brown rice input hopper 2, rice milling device 1
The unmanned rice milling facility is equipped with a de-stoning device 8 and a rice polishing device 18 in the previous stage of the de-stoning device 8, and is provided with a de-stoning drive control means that can drive only the de-stoning device 8 in advance of other devices. This is the configuration of the stone removing device for an unmanned rice milling facility.

[Operations and Effects of the Invention] When milling sticky rice in an unmanned rice milling facility, for example, due to the operation of a sticky rice polishing button, only the stone removing device 8 may be driven before other devices. The de-stoning drive control means operates, and the previously milled non-glutinous rice distributed over the entire surface of the sorting plate 10 of the de-stoning device 8 can be discharged, and the mochi rice can be transferred to the next person who wishes to mill the rice. The contamination of non-glutinous rice can be prevented in the stone removal device 8, and by removing the non-glutinous rice distributed over a wide range on the sorting plate 10 of the stone removal device 8, The purpose is to prevent the mixing of non-glutinous rice with glutinous rice and eliminate the drawbacks of conventional devices.

[Examples] Examples of the present invention shown in the drawings will be described below.

First, the configuration of the embodiment will be explained. 1 is
This is the building where the unmanned rice milling facility will be installed.
The room is divided by a partition wall 3 into a brown rice input room 1a where a person who wants to mill rice supplies brown rice to an input hopper 2, and a machine room 1b where a rice milling facility is installed. A wire mesh 4 for removing foreign matter is stretched over the upper part of the input hopper 2, and the brown rice input into the input hopper 2 is supplied to the lower part of the elevator 6 by a supply helix 5 at the bottom. The brown rice fried by the elevator 6 is supplied from a hopper 7 of the elevator 6 to a destoning device 8.

This stone removing device 8 is a well-known device and is constructed as follows. Sorting plate 10 vibrating on stone removal frame 9
is provided obliquely, and a stone removal path 11 is provided in series on the upper side of the slope of the sorting plate 10, and stones that have moved to the upper side of the slope due to vibration are discharged from this stone removal path 11. The brown rice from which stones have been removed flows down from the inclined lower side of the sorting plate 10 and is taken out. This stone removal path 11 is configured with a brown rice removal hole 12 that can be opened and closed freely.
At one end of the opening/closing plate 13 that opens and closes the opening/closing plate 13
A spring 14 is connected to the opening/closing plate 13, and one end of an interlocking wire 15 is connected to the other end of the opening/closing plate 13. A solenoid 16 is attached to the other end of the interlocking wire 15. The opening/closing plate 13 is in a closed state by the spring 14, but when the solenoid 16 is operated, the opening/closing plate 13 is pulled by the interlocking wire 15, and the brown rice removal hole 12 is opened.

The brown rice flowing down from the stone removing device 8 is transported to the second elevator 1.
The grains flow into the hopper 17a of No. 7, are fried by the second elevator 17, and are supplied to the brown rice tank 19 of the rice milling device 18. This rice milling device 18 is also well known, and although the drawings are omitted, it includes a grain feeding spiral, a bran removal screen, a milling roll,
It is composed of a pressure plate etc. that adjusts the polishing degree, and the polished rice taken out from the polished rice take-out path 20 is
The polished rice is stored in a container 22 via a tank 21. Further, the bran generated in the rice polishing device 18 is transferred to the cyclone 2 through the bran pipe 23 by a fan (not shown).
The bran that flows down from the lower part of the cyclone 24 is conveyed by the bran helix 25 and transferred to the bran bag 26.
will be stored in.

27 is an operation panel, and this operation panel 27 is configured as follows. A brown rice input ready lamp 28 lights up when the rice polishing device 18 is empty and brown rice can be input, a coin mark 30 with a coin insertion slot 29, a coin number indicator 31 that displays the number of coins to be inserted, and mochi rice being polished. It consists of a glutinous rice polishing button 32 that is pressed when cleaning, a top white button 33 that allows you to select the desired degree of polishing, a standard button 34, and an 8-minute button 35.

When the glutinous rice polishing button 32 is operated, the destoning device 8 and the solenoid 16 are activated for a predetermined period of time (for example, 1 minute) prior to the activation of other devices such as the rice polishing device 18, and the sorting plate 10 vibrates, and the solenoid 16 causes the opening/closing plate 1 to vibrate.
3 moves toward the opening side (stone removal drive control means). Then, since no new brown rice is supplied from the elevator 6, the remaining brown rice from the previous milling distributed over the entire surface of the sorting plate 10 is gradually moved to the upper side of the slope due to the vibration of the sorting plate 10. move,
The brown rice is taken out of the machine from the open brown rice removal hole 12 of the stone removal path 11. Incidentally, when driving the de-stoning device 8 in advance for a predetermined period of time, a sequence control may be performed so that the de-stoning device 8 is always performed prior to the polishing work without providing a special operation button.

The stone removal drive control means is for, after performing the preceding operation of the stone removal device 8 and the solenoid 16 for a predetermined period of time, continuing the operation of the stone removal device 8 in parallel with the drive means of other devices. be.

Next, the operation of the embodiment will be explained. When a person wishing to mill rice supplies brown rice to the input hopper 2, confirms that the brown rice input ready lamp 28 is lit, and inserts coins corresponding to the amount of input brown rice into the input slot 29 of the coin pick 30 to polish non-glutinous rice. To do so, press any of the lower upper white button 33, standard button 34, or 8 minute button 35 without pressing the glutinous rice polishing button 32. Then, all parts of the device are driven at the same time, and the loaded brown rice is cleaned of foreign matter such as straw waste by the foreign matter removal wire mesh 4 of the input hopper 2.
The grain is fed to the lower part of the elevator 6 by the supply helix 5 at the bottom, then fried by the elevator 6, and fed from the hopper 7 of the elevator 6 to the destoning device 8.

The brown rice supplied to the stone removing device 8 is sorted by a vibrating sorting plate 10, and foreign objects such as pebbles are moved to the upper side of the inclined side of the sorting plate 10, and then passed through the stone removing path 11.
The brown rice is discharged to the outside, and the brown rice flows to the lower inclined side of the sorting plate 10 and is taken out together with the brown rice that is subsequently supplied.

The brown rice flowing down from the stone removing device 8 is transported to the second elevator 1.
The rice flows into the hopper 17a of No. 7, is fried by the second elevator 17, is supplied to the brown rice tank 19 of the rice milling device 18, is then polished by the rice milling device 18, and the polished white rice is taken out from the take-out path 30 and sent to the polished rice tank. 21 and then stored in a container 22. Further, the bran generated in the rice milling device 18 is sent to the cyclone 24 via the bran pipe 23 by a fan (not shown).
The bran flowing down from the lower part of the cyclone 24 is conveyed by a bran helix 25 and stored in a bran bag 26.

Next, when polishing sticky rice, put the sticky rice into the input hopper 2 and the brown rice input lamp 2.
8 is lit, insert the coins corresponding to the amount of mochi rice to be inserted into the slot 29 of the coin pick 30, press the mochi rice polishing button 32, and then press the lower upper white button 33, standard button 34 or 8. minute button 3
Press one of 5.

Then, when you press the mochi rice polishing button 32,
The stone removing device 8 is driven in advance of the other rice milling devices 18, etc., and the stone removing device 8 and solenoid 16 operate in advance for a predetermined period of time (for example, 1 minute), the sorting plate 10 vibrates, and the solenoid 16 opens and closes the plate. 13 moves to the opening side. Then, the non-glutinous rice that remains from the previous milling and is distributed over the entire surface of the sorting plate 10 is gradually moved to the upper side of the slope due to the vibration of the sorting plate 10, since no new brown rice is supplied from the elevator 6. The brown rice is then taken out of the apparatus through the open brown rice removal hole 12 of the stone removal path 11.

In addition, when discharging the remaining unpolished rice from the stone removal device 8, the inclination angle of the sorting plate 10 may be made steeper.

When the removal work of the rice remaining in the stone removing device 8 is completed, the other devices such as the rice polishing device 18 and the elevator 6 are operated by sequence control, and the stone removing device 8 is restarted, and the above-mentioned non-glutinous rice is polished. The polishing work is carried out in the same way as in .

Therefore, when polishing glutinous rice, by operating the glutinous rice polishing button 32 on the operation panel 27, only the stone removing device 8 can be driven to discharge for a predetermined period of time before other devices. It is possible to discharge the non-glutinous rice that was distributed over the entire surface of the sorting plate 10 of the removing device 8, and to prevent the non-glutinous rice from being mixed into the mochi rice of the next person who wishes to mill the rice. It is something that can be partially prevented,
By removing the non-glutinous rice distributed over a wide area on the sorting plate 10 of the destoning device 8, mixing of the previous non-glutinous rice over a wide range is prevented, thereby solving the drawbacks of the conventional device.
