  Based on the drawings, the coin milling machine partitions the inside of the house 7 of the building by a partition wall 8 and divides and configures an operation room 9 and a machine room 11 in which the rice milling apparatus 10 and the like are installed. A user who uses this coin milling machine enters through the door opening 12 of the operation room 9, brings in the brown rice to be polished, supplies it to the brown rice hopper 1 provided on the partition wall 8, and supplies the polished rice by the rice milling apparatus 10. The rice is taken out into the white rice hopper 13 as white rice. The partition wall 8 is provided with an operation panel 14 at the center, and the brown rice hopper 13 on the front side of the left and right side brown rice hopper 13, the closing shutter 3, etc., and the white rice hopper 13 on the left and right other side. Etc.

  On the partition wall 8 side of the machine room 11, the brown rice hopper 1 is provided at the left end, and the white rice hopper 13 is provided at the right end. In the machine room 11, a stone extraction device 15 that receives and removes brown rice supplied and transported from the brown rice hopper 1, a rice milling device 10 that receives the selected brown rice and polishes the rice, and between them The arranged rice milling devices 16, 17, etc. can be arranged, and the white rice polished by this rice milling device 10 can be taken out to the white rice hopper 13.

  Further, a washing-free rice hopper 18 for temporarily storing the white rice taken out from the rice milling apparatus 10 is provided at the side of the rice milling apparatus 10, and the white rice stored in the washing-free rice hopper 18 is again used in the above-mentioned rice mill 17. Is supplied to the rice milling apparatus 10 and polished to be washed out and washed to the white rice hopper 13.

On the upper side of the brown rice hopper 1, a brown rice charging port 2 communicating with the operation chamber 9 is formed, and a charging shutter 3 capable of opening and closing the brown rice charging port 2 is provided.
The operation panel 14 has a coin insertion slot 4 for inputting a fee, a barcode sensor (not shown) for reading a barcode instead of inserting a coin, a return lever 21 for returning a fee, and a fee display for displaying an insertion fee. A window 22, an abnormal display pilot lamp 23, and the like are arranged. Further, below the coin insertion slot 4, as a milling degree selection switch 5 for selecting a milling work course, an upper white switch 5C, a standard switch 5D, an eight-minute switch 5E, and a no-wash rice switch 5F are provided. Furthermore, a shutter switch 6 for continuously operating the polished rice while continuously feeding the brown rice to the brown rice hopper 1 is provided. Reference numeral 20 denotes a speaker for voice guidance.

  Here, a coin insertion slot is provided which is provided with a closing shutter 3 for moving the brown rice into the brown rice hopper 1 and moving it up and down to close or open it, and starts a rice milling operation upon receiving a predetermined rice polishing fee. 4 and a coin milling machine provided with a milling degree selection switch 5 for determining the milling degree of the rice milling operation and starting the milling process, by charging the coin insertion slot 4, the opening shutter 3 is opened and the brown rice is inserted. And the closed shutter 3 is closed after the start of the rice milling. When the brown rice brought in is to be polished, a rice polishing fee (coins) corresponding to the amount of brown rice to be polished is inserted into the coin insertion slot 4. The rice milling apparatus 10 is operated by this charge input, and the input shutter 3 of the brown rice input port 2 is opened so that the brown rice can be input to the brown rice hopper 1 from the brown rice entrance 2. A predetermined amount of brown rice is thrown into the brown rice hopper 1 through the brown rice slot 2 opened by the shutter 3. Here, when the milling degree selection switch 5 is selected and operated, the rotary valve 30 starts to be driven to perform the brown rice milling operation by the rice milling apparatus, and the throw shutter 3 is closed by the start of the rice milling operation.

  During the rice milling operation, when the amount of brown rice brought in is large and additional brown rice is added, or when the state in the brown rice hopper 1 is checked, the shutter 3 is opened by operating the shutter switch 6. When the additional brown rice is thrown in or the current brown rice amount is confirmed and the shutter switch 6 is operated again, the throwing shutter 3 is closed. As described above, the closing shutter 3 during the operation of the rice milling apparatus is maintained in the closed state by driving the rice milling apparatus by operating one of the milling degree selection switches 5, but by operating this shutter switch 6, Since it can be opened, it is convenient when adding additional brown rice to the brown rice hopper 1 and continuing the rice polishing.

  Alternatively, instead of the shutter switch 6, the whitening degree selection switch 5 can be used to open the closing shutter 3, and additional brown rice can be used by using other switches without providing a special switch. It is also possible to adopt a form that makes it easy to input the. In addition, when adding additional brown rice, before or after the completion of the initial rice milling, an additional rice milling fee is introduced into the coin insertion slot 4 so as to be detected by the fee insertion sensor 28 and output from the controller 29. Therefore, a configuration may be adopted in which the closing shutter 3 of the brown rice inlet 2 is opened. Here, by adding additional brown rice from the brown rice input port 2 to the brown rice hopper 1, the drive of the rice milling apparatus can be extended to continue the additional brown rice. At this time, when a predetermined time elapses after the closing shutter 3 is opened or the shutter switch 6 is operated, the closing shutter 3 is closed and the rice milling operation is continued as described above.

  In addition, in the rice milling operation, when the insertion fee for the coin insertion slot 4 is mistakenly insufficient, the rice milling operation is stopped halfway and brown rice remains in the middle of the rice milling apparatus or the like. is there. At this time, a shortage charge is inserted into the coin insertion slot 4 and any milling degree selection switch 5 is operated to resume or continue the rice milling operation. The operation of the switch 5 makes it unnecessary to put in brown rice, restarts the rice milling operation, and can immediately close it. It is possible to prevent brown rice from being introduced due to an erroneous operation during the milling operation.

  It should be noted that the detection of whether brown rice remains in the middle position of the above-described rice milling apparatus or the like is a temporary storage for temporarily storing the brown rice supplied to the rice milling apparatus 10 or the sensor for detecting the presence or absence of introduced brown rice in the brown rice hopper 1. It is determined by detecting the presence of brown rice by the residual brown rice presence / absence detection sensor 25 s provided in the hopper 25 and informing through the audio speaker 20.

  As another embodiment of the throwing shutter 3, as shown in FIG. 6, a throwing function having a function of opening and closing the brown rice slot 2 and a lift function of placing a brown rice bag and raising it to the height position of the brown rice slot 2. Shutter 33.

Prior to the start of the operation, the throwing shutter 33 is maintained at the closed position 33c of the brown rice slot 2 so that brown rice, foreign matter, or the like cannot be thrown from the brown rice slot 2.
By inserting the rice milling fee into the coin insertion slot 4, the insertion shutter 33 that has closed the brown rice insertion slot 2 rotates horizontally around the shutter shaft 20, so that the brown rice insertion slot 2 is Open. The opening shutter 33 that has been rotated and rotated is driven downward by a lifter with the shutter shaft 20 being guided by the lift guide 21 in the vertical direction. Then, the descent drive is stopped as the closing shutter 33 reaches the brown rice bag placement position 33a approaching the floor surface Y of the operation chamber 9. Wait for the subsequent brown rice bag G to be placed.

  The brown rice bag G brought in advance is mounted on the upper surface of the closing shutter 33 lowered to the brown rice bag placement position 33a. A weight sensor 22 composed of a load cell or the like is provided at the shutter shaft 20 portion of the closing shutter 33, and the closing shutter 33 is driven up by the weight detection by the weight sensor 22. In a state where the brown rice bag G is placed, the throwing shutter 33 is raised to the brown rice throwing position 33b which is substantially the same height as the brown rice throwing opening 2 and stops. In this state, the user opens the bag mouth of the brown rice bag G on the top surface of the charging shutter 33, discharges it onto the bag receiving net shelf 23 on the brown rice hopper 1, and inputs the brown rice. The brown rice supplied into the brown rice hopper 1 is detected by the brown rice sensor 24 provided in the brown rice hopper 1 and can be fed and conveyed to the cerealing machine 16 side by driving the rotary valve 30.

  In this way, while the throwing shutter 33 is stopped at the brown rice throwing position 33b in the brown rice bag placement posture, the brown rice throwing operation is performed and the weight of the brown rice bag G is not detected, or By selecting the milling degree with the milling degree selection switch 5, the brown rice bag loading posture closing shutter 33 is rotated upward around the shutter shaft 20 by the output from the controller 29, and the brown rice inlet closing position is set. It moves to 33c, and the brown rice inlet 2 is closed.

  The throwing shutter 33 can be configured so as to be appropriately rotated to the tilt opening A position at the ascending position and stopped so that the brown rice can be discharged and thrown from the brown rice bag G more easily. Such an operation of the tilt angle A position of the closing shutter 33 may be performed by providing the operation panel 14 with the shutter rotation switch 26. Alternatively, the throwing shutter 33 may be moved up and down by providing a shutter raising / lowering switch 27 to lift a plurality of brown rice bags G so that the brown rice hopper 1 can be continuously thrown into the brown rice hopper 1. Alternatively, the shutter rotation switch 26 and the shutter raising / lowering switch 27 may be combined and the closing shutter 33 may be manually operated with two switches, an up / close switch (not shown) and a down / open switch (not shown). .

  In this way, after the brown rice bag G is raised and the brown rice is put into the brown rice hopper 1, when the milling degree selection switch 5 is pressed, the rice milling device 10, the stone extraction and sorting device 15, the cerealing devices 16 and 17, etc. The rice milling work is started by driving. Then, when the rice milling operation is started, the input shutter 33 closes the brown rice input port 2 and completes the operation.

  The shutter shaft 20 which is guided by the lift guide 21 and moved up and down has a plate arm 28 and is configured to be detachable by fitting a socket 29 of the closing shutter 3. A weight sensor 22 made of a load cell is provided on the upper portion of the socket 29 of the throwing shutter 3 so that the weight of the brown rice bag supported by the throwing shutter 33 can be detected.

  As described above, in the mode in which the charging shutter 33 is opened by charging a coin into the coin insertion slot 4, it is possible to input brown rice even after the rotary valve 30 of the brown rice hopper 1 is stopped. Is performed, brown rice may remain in the brown rice hopper 1, which is not preferable. However, as described above, by closing the closing shutter 33 of the brown rice input port 2 during the rice polishing, erroneous input of the brown rice to the brown rice hopper 1 can be prevented.

  Of course, also in this embodiment, the aforementioned shutter switch 6 can be operated to open the closing shutter 33 again to perform additional charging of brown rice or confirmation in the brown rice hopper 1. Alternatively, by operating the above-described lowering / opening switch (not shown), the closing shutter 33 is opened / lowered to a desired position, and the next brown rice bag G is placed, and the up / down switch (not shown). It can also be configured to operate so that new brown rice can be introduced.

  In the rice milling control, the normal rice milling course A and the non-washing rice course B are controlled so that they can be changed even after the rice milling machine is activated. If the user selects courses A and B, or selects whiteness 5C, 5D, or 5E, and selects another whiteness while moving the whiteness 5C, 5D, or 5E position, select it first. Even if the whiteness position is being moved, the movement is temporarily stopped and the movement control is performed to the last selected whiteness position. As a result, even if the whiteness position is selected by mistake, if the user notices that he / she has made a mistake, he / she can select the desired whiteness level again, thereby minimizing unintentional mixing of different types of polished rice. can do.

  Since a waiting time is provided at each whiteness selection setting position, a confirmation calculation process is performed as to whether or not the user has been reselected at each whiteness setting position. When the user is performing reselection, control is performed so as to cancel the movement to the initial whiteness movement position and move to the reselection position.

  Since the parts of the rice milling machine wear with the operation period, the whiteness gradually decreases. For this reason, it is necessary to perform maintenance adjustment so as to maintain the whiteness constant. Therefore, the accumulated rice milling amount is stored, and control is performed to increase the whiteness when a predetermined amount of processing has elapsed. Then, since the processing amount is automatically measured and the whiteness adjustment corresponding to it is performed, maintenance can be saved. For example, when the processing amount of the polished rice is detected by the processing capacity of the rotary valve 30 at the lower part of the brown rice hopper 1 and accumulated in the control unit, when a predetermined processing amount, for example, 1 ton, is finished, Is moved to a position (for example, 0, 5 points above) where the position is increased by a predetermined whiteness, and control is performed.

  The control can be configured to start the rice milling operation when the closing shutter 33 is closed. In this case, a switch for closing the closing shutter 3 is any of the milling degree selection switches 5. The control mode is such that even if the closing shutter 3 is in the middle of closing operation, the operation of the closing shutter 3 can be temporarily stopped and opened again by the whiteness selection switch 5. can do.

  Since the rice milling apparatus 10 is activated after the brown rice is completely introduced from the brown rice inlet 2 of the user, the addition of brown rice and the interruption are eliminated. It can be used at a regular price, and rice milling time can be shortened. Even when the user is in a continuous use state, since the closing shutter 3 is closed, foreign matter cannot be put in unless a coin is inserted, so that foreign matter can be prevented from being mixed. Moreover, the danger at the time of closing the closing shutter 3 can be prevented by disposing a closing switch for closing the closing shutter 3 at a position away from the brown rice opening 2. In addition, by using the whiteness selection switch 5 as described above, an inexpensive configuration can be achieved without providing a special switch.

  Control is performed so that the rice milling operation is started when the closing shutter 3 is closed. In case of bringing in and feeding several bags of brown rice continuously, if the shutter switch 6 is pushed before the milling operation and the milling degree selection switch 5 is turned on, the milling is performed without the closing shutter 3 being closed. It is the control structure which can throw in brown rice to the brown rice hopper 1 continuously. When this rice milling apparatus 10 is selected and activated for continuous use, even if the brown rice sensor provided in the brown rice hopper 1 part is turned off, it does not shift to the end operation unless it is turned off for a predetermined time longer than usual. Control.

  Since the rice milling apparatus is started after the user has completely introduced the brown rice, there is no need to add or interrupt the brown rice. The rice can be used at a regular price and the rice milling time can be shortened. Even if there are continuous users, the closing shutter 3 is closed, and the charging shutter 3 does not open unless a fee is charged, so that no foreign matter can be introduced, so that foreign matter can be prevented from being mixed. Further, the user who uses continuously does not have to close the closing shutter 3 frequently.

  As described above, the opening shutter 3 that can be opened and closed is provided at the brown rice opening 2, and the opening shutter 3 is opened when the charging of the user is detected. After the user completes the introduction of brown rice, the shutter switch 6 provided in the operation chamber 9 is pressed so that the whiteness can be selected without closing the closing shutter 3. When the brown rice is reduced in one part of the brown rice hopper after the start of the rice milling, the user can put in the next brown rice and use it continuously. In this way, since the user is continuously used in advance, even if the detection sensor of the brown rice hopper 1 is turned off, the operation is not immediately shifted to the end operation, but is shifted to the end operation until the operation time corresponding to the usage fee. It can be controlled not to.

  Further, when a coin mech that can return coins is provided at the coin insertion slot 4, when the user returns the usage fee, the next fee must be closed unless the closing shutter 3 of the brown rice insertion slot 2 is closed. Control not to accept. Since the rice milling apparatus 10 is activated after the user completely inputs the brown rice, additional brown rice is not added and no interruption occurs. It can be used at a regular price and shortens the rice milling time. Further, even if there are continuous users, the closing shutter 3 is closed, so that no foreign matter can be put in without a charge, so foreign matter can be prevented from being mixed. If a returnable coin mech is equipped, foreign matter can be mixed after the fee is returned, which is prevented.

  An openable shutter 3 that can be opened and closed is provided at the brown rice input port 2, and the open shutter 3 is opened when the user's charge input is detected. When the user returns the input money, the input money is returned, but even if a fee is charged to be used again, it is not accepted, and the operation of closing the input shutter 3 with the sound of the speaker 20 is guided. Later, the closing shutter 3 is closed, and after detecting this closing, the charge shutter 3 is again controlled to accept the charge.

  Further, if a refund operation is performed after the closing shutter 3 is opened, the closing fee can be controlled to be refunded after the closing shutter 3 is closed.
