Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This 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 milling device, and a device drive unit that can drive these devices by inserting a coin.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 brown rice, it may damage the rice milling equipment, etc.
Since stones are mixed into the polished rice, it is necessary to install a single 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. 1
Brown rice is distributed almost over the entire top 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. A problem arises in that it is virtually impossible to work on the selected parts. (In addition, in the rice milling equipment, the very small amount of non-glutinous rice remaining at the end of the milling roll is removed at the beginning of milling, so its sorting is relatively easy and there is almost no problem.) Therefore, when polishing mochi rice with an unmanned rice milling device, the present invention provides a stone removing drive operation means that can drive only the stone removing device in advance of other devices, thereby sorting the stone removing device. By removing the brown rice distributed on the top surface of the plate prior to the rice polishing process, it is possible to prevent non-glutinous rice from being mixed into the sticky rice over a wide area.

This is an attempt to eliminate the drawbacks of conventional devices.

[Means for Solving the Problem] The technical means of the present invention for solving the above technical problem is that the brown rice input hopper 2. Stone removing device 8 in the front stage of the rice polishing device 18. An unmanned rice milling facility equipped with a rice milling device 18 and equipped with a stone removing drive operating means 32 that can drive only the stone removing device 8 in advance of other devices. This is the structure.

[Operations and Effects of the Invention] When milling mochi rice in an unmanned rice milling facility, one stone is removed by operating the stone removal drive operation means 32 that can drive only the stone removal device 8 in advance of other devices. The non-glutinous rice distributed over the entire surface of the sorting plate 10 of the removing device 8 can be discharged from the previously milled rice, and the non-glutinous rice can be removed from the mochi rice of the next applicant for milling. By removing the non-glutinous rice distributed over a wide area on the sorting plate 10 of the destoning device 8, it is possible to prevent the non-glutinous rice from being mixed with the mochi rice over a wide area, and it is possible to prevent This is an attempt to eliminate the drawbacks of the device.

[Example] Embodiments of the invention shown in the drawings will be described below.

First, the configuration of the embodiment will be explained. Reference numeral 1 denotes a building in which an unmanned rice milling facility is installed. This building 1 has a partition wall between a brown rice input room 1a where rice milling applicants supply brown rice to the input hopper 2, and a machine room 1b where the rice milling facility is installed. It is divided by 3. 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. A vibrating sorting plate 10 is installed obliquely on the stone removing frame 9, and a stone numbering passage 11 is connected to the inclined upper side of the sorting plate 10.
Stones that have moved to the upper side of the slope due to vibration are discharged from this stone count outlet 11, and brown rice from which stones have been removed flows down from the lower side of the slope of the sorting plate 10 and is taken out. be. A brown rice take-out hole 12 that can be opened and closed is formed in this koku number outlet 11, and a spring 14 that always biases the open-close plate 13 in the closing direction is attached to one end of an opening/closing plate 13 that opens and closes this brown rice taking hole 12. In addition, one end of an interlocking wire 15 is connected to the other end of the opening/closing plate 13, and a solenoid 16 is attached to the other end of the interlocking wire 15. Normally, the opening/closing plate 13 is in the closed state by the spring 14. , when the solenoid 16 is activated, the opening/closing plate 13 is connected to the interlocking wire 15.
The brown rice removal hole 12 is configured to open when the brown rice is pulled.

The brown rice flowing down from the stone removal device 8 flows into the hopper 17a of the second elevator 17, is fried by the second elevator 17, and is supplied to the brown rice tank 19 of the rice milling device 18. This love story @
18 is also well known, and although the drawings are omitted, it includes a grain feeding spiral, a bran removal net, and a whitening 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 transferred to the polished rice tank 21.
After that, it is 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), and the bran flowing down from the lower part of the cyclone 24 is conveyed by the bran helix 25 and transferred to the bran bag 26. It will be stored.

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 milling device 18 is empty and brown rice can be input. Coin mech 30 with coin slot 29. Coin number indicator 31 to display the number of coins inserted. Mochi rice polishing button to press when polishing mochi rice 32.

6, the opening/closing plate 13 is moved toward the opening side. Then, since no new brown rice is supplied from the elevator 6, the remaining brown rice distributed over the entire surface of the sorting plate 1o from the previous milling is gradually moved to the upper side of the slope due to the vibration of the sorting plate 10. The brown rice is moved and taken out of the machine from the open brown rice take-out hole 12 of the koku number outlet 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.

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 mech 30 to polish non-glutinous rice. To do this, press any of the lower upper white buttons 33, standard buttons 34, or 8 minute buttons 35 without pressing the glutinous rice polishing button 32. Then, all parts of the device are driven at the same time, and the brown rice that has been input is transferred to the input hopper. While foreign matter such as straw waste is removed by the wire mesh 4 for foreign matter removal in step 2.

The grain is fed to the lower part of the elevator 6 by the feed 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 move to the upper side of the slope of the sorting plate 10 and are discharged to the outside from the stone count outlet 11.
In addition, the brown rice is placed on the sorting plate 1 along with the brown rice that is subsequently supplied.
It flows to the lower side of the slope of 0 and is taken out.

The brown rice flowing down from the stone removal device 8 flows into the hopper 17a of the second elevator 17, is fried by the second elevator 17, and is supplied to the brown rice tank 19 of the rice milling device 18, and then to the rice milling device I.
