Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a coin milling apparatus, in which milling is performed by inserting coins. [0002] Japanese Patent Application Laid-Open No. 62-279847 discloses that
After the milling process of the brown rice supplied from the brown rice tank with a rice mill, the milling machine puts the milled rice in the stone remover, sorts and separates foreign matter such as stones, and discharges it outside the machine. A technology is disclosed in which the opening / closing valve of a quarrying machine is operated upon detection of the quarrying machine to prevent stones and the like from being mixed into the polished rice and discharge the whole amount to the outside of the machine. [0003] In a coin milling machine, it is desirable to keep the operating time of the on-off valve of the stone crusher constant after the milling operation. However, the time required for the whitening process in a rice mill differs depending on the variety, moisture, and the like. Accordingly, the time from when the sensor detects that there is no brown rice to supply to when all the polished rice is actually discharged from the polished rice mill is not constant. It is difficult to set the time for operating the on-off valve until the entire amount is discharged. That is, if the operation time is too short, the polished rice remains in the destoner, and the polished rice is mixed during the subsequent polishing operation.On the other hand, if the operation time is too long, the open / close valve is driven unnecessarily. In addition, the durability of the motor that operates the on-off valve is reduced. The present invention
Despite setting the operating time of the on-off valve of the destoner to discharge foreign matter and residual rice etc. at a fixed time, foreign matter and residual rice in the destoner after milling work is more reliably eliminated, and the brown rice to be fed in the subsequent process And remaining rice from the previous process. [0004] In order to solve such a problem, the following technical measures have been taken. In other words, a stone crusher that sorts and separates foreign matter such as stones mixed in the brown rice supplied by the supply means, a rice mill that whitens the brown rice that is separated and separated by the stone crusher, and a stone crusher and a rice mill are operated. A coin milling machine that has a slot for coins to be operated, and when a coin is inserted into the slot, a stone crusher and a rice milling machine are operated via a timer, and automatically stops after a predetermined time according to the number of coins inserted. In the device, after the end of the previous milling operation,
After stopping the supply means, by opening the stone discharge port of the destoner for a certain period of time, the foreign matter and residual rice separated and separated during the rice milling operation are discharged, and the stone discharge port is closed at the start of the subsequent step milling operation. A coin polishing machine is provided with a foreign matter discharge shutter which is in a state of being put into a state. An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a building in which an unmanned rice polishing facility is installed, and the inside is partitioned into an operation room 3 and a machine room 4 by a partition wall 2. The operation room 3 includes a brown rice input unit 5, an operation panel 6, a white rice extraction unit 7, and the like, and the machine room 4 includes an input hopper 8, a stone removal elevator 9, a stone removal machine 10, a rice mill 11 , A rice mill 12, a bran processing unit 13 and the like. As shown in FIGS. 1 and 2, the brown rice charging section 5 is provided with a brown rice table 15 in the operation room 3 side before and after the opening 14 of the partition wall 2, and is loaded in the machine room 4 side. The supply hopper 8 is provided with a supply gutter 17 provided inside the supply hopper 8, and the supply helical shaft 16 is rotatable by a motor 18 provided at one end thereof. Provided. Reference numeral 19 denotes a sieve mesh provided in the charging hopper 8. [0007] The transfer end of the supply gutter 17 is viewed from the hopper of the stone removal elevator 9, and a stone removal machine 10 is provided below the upper hopper of the stone removal elevator 9. As shown in FIG.
1. Includes a rocking mechanism 22 and the like. The rotation of the drive motor 23 causes the tilting sorting net 20 to oscillate in the direction of the arrow in FIG. It is configured to swing upward and allow brown rice to flow downward and be discharged from the outlet 24. The foreign matter discharge shutter 25 provided on the upper side of the inclined sorting screen 20 is normally kept in a "closed" state by a spring 26, and rotates forward and backward in response to the supply spiral 16 stop signal. It is opened by the data 27. Reference numerals 28 and 29 denote limit operation setting limit switches, which can set the rotation limit of the opening / closing motor 27 that rotates in reverse after maintaining the "open" state for a short time (for example, 5 seconds). The hopper of the rice mill 11 is the outlet 2 of the brown rice.
4 The rice cooker 12 has a brown rice tank 30 at the bottom of the upper tank. The rice mill 12 is of a known type in which a whitening roll 32 is provided in a whitening room 31, and the bran separated from the bran removing screen 33 is conveyed to a bran treating section 13 by a bran conveying fan 34. Reference numeral 35 denotes a rice milling motor, which is the above-mentioned whitening roll 32.
The rotation of the rice bran transport fan 34 and the like is linked. The above-mentioned polishing room 31
Is connected to a white rice tank 36 as a white rice extraction section 7. Reference numeral 37 denotes a blower fan that blows air into the refining chamber 31. The adjustment of the degree of whitening is performed by changing the elastic force of a whiteness adjusting spring 40 applied to the compression plate 39 on the outlet side by the forward / reverse rotation of the whiteness adjusting motor 38. That is, the whiteness adjusting spring 40 loosely fitted to the shaft 41 connected to the motor 38 is received by the upper receiving member 42 and the nut 43 screwed to the lower portion of the shaft 41, and is rotated by the rotation of the shaft 41. The effective length is adjusted to be longer or shorter, and the pressure of the compression plate 39 connected by the wire 44 is adjusted and changed. The upper receiving member 42 is connected to a bran removing screen 33 provided to move freely. In an overload state such as at the time of starting, the upper receiving member 42 is rotated with the whitening roll 32 to pull the wire 44, and the outlet side is opened. In this way, the load can be reduced. As shown in FIG. 2, the bran processing unit 13 includes a cyclone 45, a bran transfer spiral 46 gutter 47, and a spiral gutter 47 for horizontally transporting the bran which has fallen below the cyclone 45 and falls.
And a bran bag 48 for receiving the falling bran from the discharge part which opens to the middle part and the end side. As shown in FIG. 9, the operation panel 6 on the operation room 3 side includes a brown rice insertion possible lamp 49, a coin number display lamp 50, a coin mech 51, and a glutinous rice button 5.
2. Whiteness selection buttons 53, 54 and 55 (in the example shown, three levels of white, standard and eight) can be selected, and a charge table 56
(For example, “100 yen up to 10 kg”) and the like, among which the coin mech 51 is provided with a discrimination unit for inserted coins, a coin sensor 57 that operates for each inserted coin, and the like. The operation panel 6 is provided with a microcomputer for controlling the drive motors of the respective components. As shown in FIG. 10, the arithmetic processing unit (CPU) 58 of the microcomputer includes detection information from the coin sensor 57, whiteness selection information, a brown rice detection sensor signal described later, and a whiteness adjustment mode. A limit switch 60 signal, a clock signal, and the like, which come into contact with a cam 59 connected to the negative terminal 38, are input. On the other hand, as the output information, the supply spiral drive motor 18 control signal, the crusher 10 drive motor 23, the elevator 9,
11 drive motor 61, rice milling machine 12 drive motor 35, bran transfer spiral motor 62, etc. drive system control signals for this machine, stone opener shutter open / close motor 27 control signal, whiteness adjustment motor 38 control There are signals, etc. The CPU 58 mainly has the following functions. That is, receiving the signal from the coin sensor 57, it calculates the inserted amount or the inserted number. Insert coin (100 yen coin)
By operating the built-in timer mechanism according to the number, the motor 18 for the supply spiral 16 is driven by t 1 (135 seconds per 100 yen),
Rice-milling machine 12 drive motor 35 and lifters 9 and 11 motor 6
1 like the motor drive system motor - slightly longer t 2 (180 seconds) the data and outputs the starting and stopping signals to drive (Fig. 11 b). The brown rice tank 30 of the rice polishing machine 12 is provided with a brown rice detection sensor 63 on the wall side, and outputs the supply spiral motor 18 stop signal based on the presence or absence of brown rice detection. That is, when brown rice is detected and the brown rice detection sensor 63 is turned on, a predetermined time (t)
(3 : 30 seconds), the motor 18 stops when the sensor 63 continues to be turned ON, and is driven again when the sensor 63 is turned OFF (FIG. 11B). As shown in FIG. 2B, a set time t 1 (t 1 = t based on the number of inserted coins)
4 + t 5 + t 6) is passed a result, the set time t 7 (e.g. 3
(0 second) Outputs in order to stop the motor of the machine drive system such as the motor 35 for the rice mill 12 with a delay. If the driving time based on the number of inserted coins expires within the predetermined time t 1 , the operation is stopped after the predetermined time t 8 elapses after an extended driving time T until the brown rice detection sensor 63 is turned off. It is controlled (FIG. 11C). Before starting the work, the signal is input by pressing the whiteness selection buttons 53, 54, 55, but the whiteness adjustment motor 38 rotates forward or backward so that the whiteness according to the selected position is obtained. It reverses and is set to a preset rotational position. That is, the motor 3 is compared with the newly set whiteness from the whiteness state stored before the button setting.
While outputting the eight rotation signal, the degree of rotation is obtained by rotation of the limit switch 60 fitted into the concave portion of the cam 59, and when a predetermined count is reached, a stop signal is output. After the operation end signal, that is, the operation time of the supply spiral 16 drive motor 18 set according to the number of inserted coins, the foreign matter discharge shutter 25 motor 27 of the stone removing machine 10 is rotated forward, and a predetermined time elapses. Then, a reverse rotation signal is output to return to the reverse rotation. Therefore, at the start of rice polishing, the shutter 25
Automatically opens and automatically discharges foreign matter such as rice and stones that have been removed before the stone removal operation, and closes automatically after a certain period of time. Next, the operation of the above example will be described. In advance, coins sufficient to secure the operation time corresponding to the amount of the raw brown rice are inserted into the insertion opening of the coin mech 51, and the brown rice is supplied to the input hopper 8. Then, each part of the apparatus starts to operate at the same time as coin insertion, and brown rice from the input hopper 8 is horizontally transferred by the supply spiral 16 and is input into the stone removal / lifting machine 9. The brown rice discharged from the upper part of the elevator 9 enters the destoner 10 and is rocked or subjected to a wind selection process to remove stones and remaining rice mixed in the rice grains. The brown rice from below the sorting net 20 is supplied to the rice mill 11 to be lifted and supplied into the brown rice tank 30. The brown rice that flows into the polishing room 31 of the rice polishing machine 12 is a polishing roll 3
By the rotation of 2, the bran layer on the surface is peeled and refined between the grains and the bran removing screen 33. At this time, the compression plate 39 at the exit
Is set to a desired pressure by the whitening selection button, and the desired whiteness is finished. The milled rice from the milling chamber 31 is appropriately collected in the operation room 3 through the milled rice extracting section 7. Since data is stopped - operation each part driving the time t 1 set by the paid amount is passed first supplied helix 16 motor - motor 18 is stopped, the predetermined time t 2 later rice mill, etc. the machine drive motor Thus, the amount of brown rice remaining in the elevators 9 and 11 and the polishing room 31 can be reduced. During the above operation, the flow rate of the brown rice flowing down from the rice mill 11 and the processing amount of the rice mill 12 are set to substantially match each other.
It is not uniform due to the amount of water and the like, so brown rice stagnates in the brown rice tank 30 when the amount of polished rice drops, and the brown rice detection sensor 63 turns on when the stagnation amount gradually increases. Also this state continuously for a predetermined time t 3 Note that when the sensor 63 is ON driving motor of the feed helix 16 - motor 18 stops once the supply of the new raw materials is stopped. Since the motor 35 of the rice mill 12 is continuously driven, the whitening process is continued and the sensor 63 is delayed.
Turns off. At the same time, the motor 18 of the supply spiral 16 is started again to restart the supply of the raw material. On the other hand, when the driving time has expired within the above-mentioned predetermined time t 3 , after the extended driving time T until the brown rice detection sensor 63 is turned off, and the safe driving time of the predetermined time t 8 , the rice mill 12 or the like is stopped. The motor for driving the machine is stopped, and the drive for the rice milling machine 12 or the like is not stopped simply after the time lags t 2 and t 7 with respect to the drive stop reference of the supply spiral 16. It is advantageous. Upon receiving a drive stop signal of the supply spiral 16, specifically, a drive motor 18 stop signal, the drive motor of the discharge shutter 25 of the stone cutter 10 rotates forward to open the opening.
Thus, foreign substances and the like remaining on the sorting net 20 can be discharged and can be prevented from being mixed in the next rice polishing operation. According to the present invention, after the stones and the like in the brown rice supplied by the supply means are separated and sorted by the stone remover, the rice is milled by the rice mill. Then, after finishing the milling operation, after the supply means is stopped, that is, after brown rice is no longer supplied to the destoner, the debris discharge shutter of the destoner is operated to open the stone discharge port to remove debris such as stones and residual rice. Discharge. Therefore, by operating the foreign matter discharge shutter for a certain period of time after the completion of the milling operation, it is possible to reliably remove foreign matter, residual rice, and the like after the milling operation in the destoner. As a result, it is possible to prevent the brown rice thrown in the subsequent process from mixing with the remaining rice in the previous process.
