Description

The present invention relates to a rice milling facility for milling brown rice brought by a user.

An elevating device for raising and lowering the mounting table is provided at the position of the cabin facing the loading hopper, and the lifting device is equipped with a mounting table, a lifting device for raising and lowering the mounting table, and a support for supporting the lifting device from below. It is known that the configuration is such that it can be raised from the lowest initial position toward the height of the charging position of the charging hopper (Patent Document 1).

JP-A-2019-63681

Since the mounting table of Patent Document 1 can be raised, it is excellent in that labor can be reduced to the height at which it is put into the hopper. However, the floor of the guest room may be wet during rainfall or snowfall. In this state, while the polished rice from the white rice tank is collected in a bag and the opening of the bag is closed, such as by tying a string, the bag comes into contact with the floor and is made of wet paper, so there is a risk of damage. In view of the above, the present invention makes it possible to close the bag mouth portion without getting the storage bag wet by using the mounting table even if the floor surface F of the guest room is wet. In addition, the platform can be used appropriately when bringing back a small amount of brown rice left in the rice milling process.

In order to solve such a problem, in the invention according to claim 1, the building is divided into a guest room K where a user enters and exits and a machine room M provided with a rice milling machine 5, and brown rice put into a rice milling hopper 2 is used as a rice milling machine 5. In the rice milling equipment for rice milling and discharging the polished rice from the rice milling machine 5 to the milled rice tank 7, an elevating device 9 provided with a mounting table 14 is provided at a position on the K side of the guest room facing the charging hopper 2, and the elevating device 9 elevates and elevates. The mounting table 14 is raised and lowered by the operation of the switch 12 and the elevating signal from the control unit A, and a brown rice presence / absence detection sensor 13 for detecting the presence / absence of brown rice in the charging hopper 2 is provided, and the brown rice presence / absence detection sensor 13 determines the absence of brown rice. It is characterized in that the mounting table 14 is configured to be automatically lowered when it is detected.

The invention according to claim 2 is configured to raise the mounting table 14 in response to the input of the brown rice return switch 24 which is operated when the brown rice remaining in the charging hopper 2 is brought back in the invention according to claim 1.

The invention according to claim 3 includes a person detection sensor 10 capable of detecting the presence or absence of a person in the guest room K in the invention according to claim 2, and when the person detection sensor 10 detects the absence of a person, the mounting table 14 is used. It is configured to be automatically lowered, and even if the person detection sensor 10 detects the presence of a person, the mounting table 14 is automatically lowered when the charge input to the charge input port 19 is detected.

According to the invention of claim 1, the loading table 14 can be automatically lowered by the time the rice milling is completed, and the storage bag h containing the polished rice can be easily placed on the loading table 14 and the bag. Since the opening can be closed, the storage bag h does not have to be placed directly on the floor surface F of the guest room K, and there is no problem even if the floor surface F is wet with rainwater.

According to the invention of claim 2, in addition to the effect of claim 1, the mounting table 14 can be raised and used as a table for a bag for storing the remaining brown rice, which can reduce labor for the user.

According to the invention of claim 3, in addition to the effect of claim 2, the mounting table 14 is automatically lowered when a fee is charged, so that the person detection sensor 10 continues to have a person while waiting for a turn or the like. Even in this case, the mounting table 14 can be efficiently lowered, which can contribute to light labor.

The charge-type rice milling equipment according to the embodiment of the present invention will be described.

The basic configuration of the rice milling equipment will be described with reference to FIGS. 1 to 4.

A partition wall 1 partitions the inside of the building T into a guest room K for users to enter and exit and a machine room M in which each device is provided. In the present embodiment, the K side of the guest room is referred to as the front, and the M side of the machine room is referred to as the rear.

In the machine room M, a grain frying machine 3 for frying brown rice put into the input hopper 2 by the user, a stone removing machine 4 for removing stones mixed in the brown rice, and a second for frying brown rice from the stone removing machine 4. A rice milling machine 3a and a rice milling machine 5 for milling brown rice are provided.

A switching valve 21 is provided on the discharge side of the grain raising machine 3, and brown rice is supplied to either the stone removing machine 4 side or the brown rice return port 22 side on the loading hopper 2. It is possible to return the brown rice to the brown rice return port 22 above the charging surface of the charging hopper 2 via the brown rice returning cylinder 23.

On the K side of the guest room, there is an input hopper 2 for inserting brown rice brought by the user, an opening / closing door 6 for closing / opening the input port of the input hopper 2, and a mill for storing polished rice processed by the rice mill 5. A white rice tank 7, an operation panel 8 operated by the user, and an elevating device 9 described later are provided. In addition, a person detection sensor 10 is provided so that the presence or absence of a person (user) in the guest room K can be detected.

The operation panel 8 is provided with a milling degree selection switch 11 for selecting the milling degree for rice milling, and a lifting switch 12 capable of raising and lowering the charge input port 19 for charging the charge and the lifting device 9. The elevating switch 12 includes an ascending switch 12a and a descending switch 12b. Further, a brown rice return switch 24 is provided in the vicinity of the brown rice return port 22, and when the brown rice return switch 24 is operated, the brown rice in the input hopper 2 can be discharged from the brown rice return port 22 via the grain raising machine 3 and the brown rice return tube 23. It is configured in.

FIG. 1 shows a state in which the opening / closing door 6 is opened and the brown rice in the bag h can be charged into the charging hopper 2.

Below the charging hopper 2, a brown rice presence / absence detection sensor 13 for detecting whether or not there is brown rice in the charging hopper 2 is provided.

A control unit A is provided in the operation panel 8 of the rice milling equipment, and the control unit A controls each part of the rice milling equipment as shown in FIG. 4 in the block diagram thereof.

An elevating device 9 is provided in front of the loading hopper 2. The elevating device 9 raises and lowers the mounting table 14 on which the bag h for accommodating the brown rice brought by the user is placed, the weight scale 15 for detecting the weight of the bag h placed on the mounting table 14, and the mounting table 14. A lifting tool 16, a support 17 that supports the lower portion of the lifting tool 16, and a resin protective cover 18 that covers the periphery of the lifting tool 16 are provided.

The lifting tool 16 includes an X-shaped link portion 16a in which a plurality of inverted X-shaped links are continuously combined, and an electric cylinder 16b that converts the rotation of the electric motor 16m into a linear motion. The X-shaped link portion 16a is mounted by appropriately pivotally connecting the upper end to the above-mentioned stand 14 and the lower end to the support 17, and pivotally connecting the ends and the intermediate portions as shown in the figure. 14 is configured to be able to move up and down with its mounting surface in a horizontal state. Then, the cylinder base of the electric cylinder 16b is connected to the support base 17a provided on the support body 17, and the tip of the piston portion of the electric cylinder portion 16b is connected by using the reinforcing frame 14a formed at the bottom of the mounting base 14. The electric cylinder 16b is extended by the forward rotation of the electric motor 16m and shortened by the reverse rotation to move the mounting table 14 up and down. While the ascending switch 12a is pressed and turned on, the electric motor 16m is rotated in the normal direction to raise the mounting table 14 to an arbitrary height, and while the descending switch 12b is pressed, the electric motor 16m is reversed to raise the mounting table 14 to an arbitrary height. It is something that descends.

The protective cover 18 will be described in detail. In the illustrated example, the four-stage cover member is configured to sequentially polymerize the upper cover member on the lower cover member. Among the cover members, the uppermost cover member 18u has a box shape with an opening facing downward and can mount the above-described stand 14, and is reinforced by a reinforcing frame 14a. The lowermost cover member 18d is the support base. It is fixed to 17 and integrated with the support base 17 to form a box shape having an opening facing upward, and the support base 17a is incorporated therein. A plurality of intermediate cover members, a first intermediate cover member 18m1 and a second intermediate cover member 18m2, are provided between the lowermost cover member 18d and the uppermost cover member 18u.

Here, regarding the interlocking connection configuration of the protective cover member 18, the pin member 29m1 provided in the first intermediate cover member 18m1 is fitted and connected to the vertically elongated hole 28d of the lowermost cover member 18d, and similarly, the first intermediate cover member 18m1 is connected. The pin member 29m2 provided in the second intermediate cover member 18m2 is fitted and connected to the vertically elongated hole 28m1 of the second intermediate cover member 18m2, and similarly, the pin member 29u provided in the uppermost cover member 18u is fitted in the vertically elongated hole 28m2 of the second intermediate cover member 18m2. It is connected together.

Since the X-shaped link portion 16a is lowered as described above, the first intermediate cover member 18m1 is polymerized outward with respect to the fixed lowermost cover member 18d, and then the first intermediate cover member 18m1 is formed. On the other hand, the second intermediate cover member 18m2 is polymerized on the outer side, and then the uppermost cover member 18u is polymerized on the outermost side with respect to the second intermediate cover member 18m2. On the contrary, as the X-shaped link portion 16a rises, the uppermost cover member 18u rises, and then the second intermediate cover member 18m2 and the first intermediate cover member 18m1 rise in this order. During the ascending action, the lower cover member 18 acts in the direction of pulling up the entire cover member 18 when the pin member 29 reaches the upper end of the vertically elongated hole 28.

The first intermediate cover member 18m1 and the second intermediate cover member 18m2 are not required on the side wall of the building or the partition member side from the machine room because they are intended for the safety of the user standing in the guest room K. The front side F and the side S side facing each other are formed in a plan view L shape. Further, by providing the vertically elongated hole 28 and the pin member 29 at a plurality of locations of the protective cover 28, stability during operation can be ensured. For example, three places are provided on the front side F and two places are provided on one side S.

The pin member 29 has a detachable structure including, for example, a bolt and a nut. Therefore, the first intermediate cover member 18m1 and the second intermediate cover member 18m2 can be removed from each other even when the mounting table 14 is in the raised position, and inspection and repair from the side surface are possible. When visually recognizing the inside such as inspection work, the first intermediate cover member 18m1 and the second intermediate cover member 18m2 are supported from the lower side by removing the pin member 29m1 that fits into the vertically elongated hole 28d of the lowermost cover member 18d. It is convenient because it can be lifted up along the vertically elongated hole 28.

Next, a smooth operation means for facilitating sliding of cover members with polymerization or separation will be described. The pin member 29 is attached to the cover member 18, but a resin spacer 26 is provided on the pin member 29 side in order to properly secure a distance from the mating vertically elongated hole 28. With this configuration, the pin member 29 along the vertically elongated hole 28 can be smoothly operated. The reference numerals in the figure match the reference numerals of the pin member 29. Since it is made of resin, friction on the contact surface with the cover member can be reduced and sliding can be performed smoothly. The outer shape of the resin spacer 26 is arbitrary, but a ring-shaped color form can be used for further smoothness.

Next, the rice milling operation will be described with reference to FIG. First, a case where about 30 kg of brown rice, which is the most common scene, is brought in and 300 yen is put into the rice polishing process will be described.

The user prepares a bag h (for example, 30 kg) containing the brown rice brought in and enters the guest room K. When the charge detection sensor 20 detects that a charge (for example, 300 yen) has been input to the charge input port 19 (S101), the opening / closing door 6 opens (S102), and brown rice can be charged into the input port of the input hopper 2. Become. After the charge is charged, when the user places the bag h on the mounting table 14 in the initial position, that is, the lowering position (S103) and turns on the raising switch 12a to raise the mounting table 14 of the lifting device 9 (S104), the weight is increased. The weight is detected by a total of 15, and is displayed on the display screen 25 of the operation panel 8. At this time, when the weight scale 15 detects a weight within the set range (for example, 10 kg or more and less than 40 kg) (S105), the electric motor 16 m is driven in the forward direction, and the mounting table 14 is used as the loading surface of the loading hopper 2. It rises to substantially the same height (S106, S107). Alternatively, the mounting table 14 may be raised by automatically driving the electric motor 16m in the forward rotation regardless of the rise switch 12a after the charge is charged. The user throws the brown rice in the bag h into the throwing hopper 2 (S108).

If NO is determined in S105, that is, if the weight outside the set range or no weight is detected, the lifting device 9 is restricted from rising, and a warning is displayed on the display screen 25 to that effect (S109, S110). The case without weight detection is a case where the user himself lifts the bag h from the outside of the lifting device 9 and throws it into the loading hopper 2. In such a case, it is not necessary to drive the lifting device 9. Moreover, raising the elevating device 9 is not preferable from the viewpoint of safety. Further, if it is equal to or more than the set range (40 kg or more), it may be determined that the user is on the mounting table 14, and in such a case, it is preferable to raise the elevating device 9 from the viewpoint of safety. Because there is no such thing.

The weight detection value by the weight scale 15 may be configured to be a safety criterion without being displayed on the display screen 25.

When the user selects the whitening degree selection switch 11 (S111), each operation part is driven and the rice milling operation (normal operation mode) is started (S113, S114). When the rice milling operation continues for the time corresponding to the input charge (S115) and the brown rice presence / absence detection sensor 13 detects the absence of brown rice during the rice milling operation (S116), the residual rice in the rice milling machine 5 is milled (residual rice operation). Mode) and end the rice milling operation (S119 to S121).

By the way, when the whiteness setting switch 11 is not operated in S111, a notification prompting the setting is given (S112). Further, when the brown rice presence / absence detection sensor 13 detects the absence of brown rice in S116, the electric motor 16m of the elevating device 9 is reversely output and the mounting table 14 is lowered (S117, S118). By lowering it, it can be prepared for the next use, and can be used for placing a storage bag for polished rice as described later.

In S116, the determination of NO is that brown rice still remains even after the operation time for the input charge has elapsed, so that the charge has expired, the operation parts are stopped, and the display screen shows "Insufficient charge". Is displayed (S122, S123). Then, when the additional charge is input (S124), the process returns to S113 and the rice milling operation is restarted. Since the brown rice loading operation is scheduled immediately, the electric motor 16m of the elevating device 9 is reversely output to lower the mounting table 14 (S125, S126). On the other hand, when the input of the additional charge cannot be recognized in S124, the switching valve 21 is switched and the brown rice is collected from the return port 22 by operating the brown rice return switch 24 (S127, S130). When the brown rice return switch 24 is turned on in S127, the electric motor 16m of the elevating device 9 is output in the forward direction to raise the mounting table 14 (S128, S129).

The labor can be reduced by receiving the brown rice discharged from the brown rice return port 22 viewed above the charging surface of the charging hopper 2 in a bag, placing it on the raised mounting table 14 and taking it out.

As described above, when the execution of the residual rice processing operation mode is completed, each operation unit is stopped and output, and the rice milling operation is completed (S120, S121). The user puts the polished rice, which has been milled by the rice milling machine 5 and is stored in the polished rice tank 7, in the bag h, and takes it home. By the way, the bag h is viewed below the polished rice tank 7, the shutter is opened, and the polished rice is stored in the bag h (S131, S132). After the storage is completed, the user can hold the raised polished rice storage bag h with both hands and take it out from the rice polishing equipment (S133). Here, if the floor surface F of the guest room K is wet due to rainy weather, snowy season, or the like, the storage bag h is made of paper, which causes a problem. In such a case, since the mounting base 14 of the elevating device 9 is lowered in S117 and S118, the bag h for containing polished rice is placed on the elevating device 9 to close the opening of the bag such as stringing. This prevents contact with the floor surface F and eliminates the above-mentioned drawbacks.

When the person detection sensor 10 detects that no one is present after the rice milling operation is completed (S134), the opening / closing door 6 is closed and the work is completed (S138), but when it is determined in S134 that there is no person detection output. It is determined whether the mounting table 14 is in the ascending position or the descending position, and when the mounting table 14 is in the ascending position, the electric motor 16m is reversed to lower the mounting table 14 (S136, S137).

Since the mounting table 14 is lowered in S117 and S118, the S135 is determined to be in the lowered position if there is no subsequent rising output, but the mounting table 14 is raised in S128 and S129 or the raising switch 12a is operated due to some need. Is performed, S135 is determined to be an ascending position.

As described above, the elevating device 9 can place the bag h for accommodating the polished rice in the polished rice tank 7, and there is no possibility that the bag h will be immersed in rainwater. If the lifting device 9 is raised to an arbitrary position in S133, the bag h of the mounting table 14 in the raised position may be lifted when the lifting device 9 is lifted for taking out, and the bag h on the floor surface F may be lifted. The burden of lifting can be reduced, and the bag h containing polished rice can be easily handled.

As described above, the labor of lifting the brown rice can be reduced by configuring the elevating device 9 until the user polishes the brown rice brought in and brings back the polished rice. Further, when the user is working in the guest room K by the protective cover 18 of the elevating device 9, the elevating tool 16 of the elevating device 9 is driven to prevent accidents such as entanglement of fingers and clothes, which is safe.

Next, the operation of the lifting device 9 when continuously polishing a large amount of brown rice (for example, 60 kg) will be described.

The capacity of the charging hopper 2 is usually about 40 kg, and when more brown rice is charged, it is necessary to separately charge the brown rice.

Therefore, when the elevating device 9 is in the ascending position during the rice milling operation, it is necessary to lower it to the initial position. Therefore, the elevating switch 12 is configured to be operable during the rice milling operation. However, in the following cases, the lifting operation is restricted.

As a case of restricting the lowering operation, it is a case where a set weight or more (for example, 40 kg or more) is detected. In this case, the user may be sitting on the mounting table 14, which is not preferable for safety. If the weight is less than the set weight or no weight is detected, the weight can be lowered by the lowering switch 12b.

A new bag h containing brown rice is placed on the lowered mounting table 14, and the bag h is raised by the ascending switch 12a. Also in this case, when the set weight or more (for example, 40 kg or more) is detected, the increase is restricted. This is because, as described above, the user may be on the mounting table 14.

After the brown rice is charged into the charging hopper 2 after being raised to the raised position, the same as the rice milling operation according to FIG. 7 is performed.

If an increase or decrease in weight is detected in a short time during the ascending / descending operation of the mounting table 14, it is desirable for safety to stop. The increase is, for example, when the user gets on as described above, and the decrease is when the bag h collapses and the brown rice in the bag h is scattered in the guest room K.

Next, based on FIG. 10, the regulation for raising and lowering the mounting base 14 of the lifting device 9 will be described. After the brown rice bag h is placed on the loading table 14 and the charge is charged, when the ascending switch 12a is turned on, the mounting table 14 of the elevating device 9 rises, so that the operator loads the brown rice into the loading hopper 2 (S201 to S203). ). Then, when the whitening degree selection switch 11 is operated, the rice milling operation is started (S204, S205).

It is determined whether or not the elevating switch 12 is turned on. That is, it is determined whether or not the ascending switch 12a or the descending switch 12b is turned on (S206). Then, it is determined whether the operation of the ascending switch 12a or the descending switch 12b is operated more than the limited number of times (S207). Here, as a reference example of determining the operation for the limited number of times or more, the ascending switch 12a and the descending switch 12b are set as one set, and the ascending switch 12a when the mounting table 14 is in the descending position is more than a predetermined number of sets (for example, 3 sets). The number of operations is a predetermined number of times (for example, 3 times) or more, and the number of operations of the lowering switch 12b when the mounting table 14 is in the ascending position is a predetermined number of times (for example, 3 times) or more.

If the determination is less than the predetermined number of times in S207, the mounting table 14 is raised or lowered according to the operation of the lifting switch 12 (S208), but if the number of times is more than the predetermined number in S207, the lifting switch 12 is operated. However, the lifting operation of the mounting table 14 is restricted (S209).

Then, when the brown rice presence / absence detection sensor 13 operates and detects that the amount of brown rice in the charging hopper 2 is equal to or less than the set amount (S210), the rice milling operation ends (S212), but before that, the mounting table 14 is lowered (S211). .. If the set amount or more remains in S210, it is determined whether or not the charge has expired (S213). If it is determined to be Yes in S213, that is, it is recognized that brown rice remains in the input hopper 2 even after the rice milling work time commensurate with the initial input charge has passed, and no additional charge is input. It reaches S212 and the rice milling operation is completed. On the other hand, if No is determined in S213, it is determined that the input charge is within the range (including the addition of the intermediate charge), and the rice milling operation is continued.

By the way, the rice milling operation is terminated in S212, and after that, it is determined whether or not the position of the mounting table 14 of the elevating device 9 is raised by operating the raising switch 12a (S214). When it is determined that the mounting table 14 is raised by operating the ascending switch 12a and the person detection sensor 10 is turned off and it is determined that no person is in the guest room K (S215), the mounting table 14 is lowered (S216). .. The next time the user brings in the brown rice bag h, the lower the mounting table 14, the better the workability.

By restricting the lifting operation of the mounting table 14 as in S207 and S209, it is possible to prevent mischief of moving up and down on the mounting table 14.

Next, the ascending / descending operation of the elevating device 9 when automatically ascending / descending during the rice milling operation will be described. After the rice milling operation is completed and the person detection sensor 10 no longer detects a person in the guest room K, the mounting table 14 descends and returns to the initial position, but there are other timings as follows. For example, when the rice milling operation is started by operating the whitening degree selection switch 11, the mounting table 14 may be controlled to be lowered to the initial position. When there is the next bag h containing unpolished brown rice, it is possible to quickly prepare to charge the bag h containing brown rice to be charged into the charging hopper 2 into the charging hopper 2.

The lifting operation of the lifting device 9 when the rice milling operation is stopped due to the charge running out (S116) after the operation time corresponding to the charge according to the embodiment of FIG. 9 has elapsed will be supplementarily described.

When the rice milling operation is stopped even though the brown rice presence / absence detection sensor 13 detects the presence / absence of brown rice, there are the following three cases. The first is the case of inputting an additional charge (S124). In this case, the rice milling operation is started (restarted) as shown in FIG. The second is a case where the user returns as it is without noticing a small amount of brown rice remaining in the input hopper 2 or the remaining brown rice. In this case, when the person detection sensor 10 detects that there are no more people in the guest room K (S134), the opening / closing door 6 is lowered to close the door 6. Third, when the brown rice return switch 24 is operated (S127), the switching valve 21 switches from the stone remover 4 side to the brown rice return cylinder 23 side, and the grain raising machine 3 starts driving for a predetermined time. Then, the brown rice in the charging hopper 2 is returned to the charging hopper 2 side from the brown rice return port 22 via the grain raising machine 3 and the brown rice returning cylinder 23. The user receives and stores the brown rice returned in the bag h that he brought on the input hopper 2. At this time, if the mounting table 14 is in the raised position, the position is maintained, and if the mounting table 14 is in the lowered position, the mounting table 14 is raised to place the bag h containing brown rice on the mounting table 14. Can be lowered. The brown rice return switch 24 is continuously operated from the brown rice return port 22 until the remaining brown rice is stored, and after the storage is completed, the polished rice that has been milled is collected, but the procedure is the same as that after S120 in FIG.

Next, a case where the weight of polished rice is displayed on the display screen 25 by using the weight scale 15 of the elevating device 9 will be described.

The user may want to know the amount of polished rice that has been milled by the rice mill 5. Therefore, after the rice polishing operation is completed, the weight of the polished rice can be displayed on the display screen 25 by placing the bag h containing the polished rice on the mounting table 14 of the elevating device 9.

When the mounting table 14 of the lifting device 9 is in the raised position at the end of the rice milling operation, the lowering switch 12b is operated to lower the mounting table 14 to the initial position, and the bag h is placed on the mounting table 14 to polish the polished rice. Can be measured and displayed on the display screen 25.

Next, the bran packing device generated by the whitening treatment of the rice milling machine 5 will be described with reference to FIGS. 2 and 3.

When the rice is milled to a predetermined degree of whitening in the rice mill 5, the bran layer peeled from the surface of the brown rice particles is sorted and separated, and the bran is removed from the rice milling chamber of the rice mill 5. This bran removal is conveyed by a suction dust remover, an organizer, or the like, and is housed in a bran bag arranged at the back side of the machine room M. When the user acquires a part of the bran pack P during such a bran removing action, the part of the bran removed from the rice mill 5 by the acquisition operation of the bran pack P is the bran pack. It is supplied to the device 50, and the bran pack device 50 packs the pack P in predetermined amounts by the film sheet F. The bran pack P packed with the pack P is received by the upper surface of the inclined bran pack chute 53 and is slid down to the guest room K side.

At this time, the bran pack P that is sequentially dropped between the rice milling machine 5 in the machine room M and the side wall of the building slides down along the inclined surface of the bran pack chute 53, and the bran pack of the partition wall 1 in the middle It flows down from the discharge port 51 into the bran pack storage room 52 on the K side of the guest room. The rice milling user can take out the bran pack P that has flowed down into the bran pack storage chamber 52 and take it home.

Further, the film roll F for acquiring the bran pack P is loaded in the inside of the bran pack storage chamber 52 in advance in performing the rice milling action, but the film roll F may be reduced by use. , When it is necessary to replace or replenish with a new film, a new film roll F can be loaded into a predetermined place in the bran pack storage chamber 52 and maintained in a state where the bran pack P can be formed.

The bran leaking from the bran removing net of the rice milling machine 5 is sucked and conveyed by a blower which is a suction and dust removal machine 30, and is blown and conveyed to the cyclone 41. Transport cylinders 44 and 45 having a spiral 43 are arranged at an upper position extending from the bran pack device 50 part of the machine room M to the bran bag chamber 42 part on the back side, and the bran separated by the cyclone 41 is placed. By the rotation of the racen 43, it can be conveyed to the bran bag D of the bran bag chamber 42, and can be packed and supplied from each discharge port cylinder 46. The geared motor 47 provided at one end of the transport cylinder 44 can be switched between forward and reverse rotation by operating the bran take-out switch 48, and the bran delivered from the cyclone 41 by rotating the racen 43 of the transport cylinder 44 in the reverse direction. Is conveyed to the discharge port cylinder 49 viewed on the bran pack device 50 on the partition wall 1 side. The bran take-out switch 48 is provided above the partition wall 1 of the guest room K so that the user can easily operate the rice bran take-out switch 48 from the guest room K.

A noise sensor 60 is provided at a predetermined position in the machine room M. The noise sensor 60 has a configuration that can input an ambient sound pressure level and convert it into a current value and output it. When installed in the machine room M, the noise sensor 60 detects the rice milling sound generated during the rice milling process of the rice milling machine 5. The noise current value rises. The noise current value during this rice milling operation is monitored, and the following control is performed. When the noise current value during a certain rice milling operation exceeds a predetermined value, the rice milling operation is completed, and when the person detection sensor 10 detects that there is no person, a temporary operation is automatically started to automatically start each part of the operation, and the noise current value. Enter. The control unit A analyzes the noise current value during this temporary operation, compares it with a preset limit current value, and if it exceeds this limit current value, stops the rice milling operation from the next time onward. The manager of the rice milling equipment is configured so that the noise current value abnormality during the provisional operation can be notified via wireless communication means or the like, and the use of the rice milling equipment is urged to be stopped.

Abnormal noise is likely to occur due to damage to parts, etc., but with the above configuration, abnormal noise that does not occur in normal operation can be detected, and abnormal stoppage of the rice milling machine can be avoided. In addition, since the rice milling machine or the like is started and checked while there are no users, the impact on sales can be reduced.

When the noise sensor 60 determines an abnormality, the set current value is set in two stages, and if the set current value exceeds the low set current value but is less than the high set current value, a display or notification to the above-mentioned administrator is performed to obtain a high current. It is configured to stop the rice milling operation immediately when the value is exceeded. By setting a low set value, it is possible to quickly respond to abnormalities and perform appropriate maintenance.

In the above embodiment, the noise sensor 60 detects abnormal noise to monitor the abnormality in the machine room M. However, the vibration sensor 61 may be arranged in each operation part in the machine room M to detect the abnormal vibration. .. For example, by providing the rice milling machine 5 with a vibration sensor 61, if it is detected that the vibration becomes stronger due to wear of each part of the rice milling machine 5, the rice milling operation is disabled. The abnormal vibration confirmation may be performed in an unmanned state like the noise sensor 60.

Next, the foreign matter removing device 31 connected to the stone removing machine 4 and the brown rice discharging side of the stone removing machine 4 will be described. As shown in FIG. 11, the stone removing machine 4 includes a tilt sorting net 4a, a fan in a fan body 4b (not shown), a swing mechanism (not shown), and the like, and is tilted by rotation of a drive motor (not shown). The sorting net 4a oscillates in the direction of the arrow in the figure and winds up to swing foreign substances such as stones and metals mixed in the brown rice upward on the slope, and the brown rice flows down the slope and is discharged. It is configured so that it can be discharged separately. A foreign matter discharge shutter (not shown) is provided on the upper side of the inclined sorting net 4a, and is always urged to the "closed" state, and receives a stop signal such as the end of rice milling operation and is linked to the "open" stone. It is a configuration that can discharge.

A foreign matter removing sorting net 31a of the foreign matter removing device 31 is provided integrally with the stone removing machine 4. The foreign matter removing and sorting net 31a can accept brown rice because its inclined upper end communicates with the inclined lower side of the inclined sorting net 4a of the stone remover 4. Light and long straw debris (hereinafter referred to as foreign matter) is mixed in the brown rice, and the foreign matter removal sorting net 31a swings together with the inclined sorting net 4a while leaking the brown rice from the mesh 31b due to a large number of punching holes. However, the configuration is such that foreign matter can be discharged from the inclined end side. A hopper-type receiving portion 32 that receives brown rice leaking from the mesh and a flow path 33 for foreign matter or the like are provided in parallel.

The degree of inclination of the foreign matter removal sorting net 31a is set to be steeper than the inclination of the inclined sorting net 4a. As a result, it is possible to prevent the foreign matter removal and sorting net 31a from staying on the surface.

A plate member 34 inclined upward toward the end is attached to the end of the foreign matter removal sorting net 31a. The plate member 34 is formed with a slit 34a in the width direction to allow the passage of brown rice. With this configuration, the plate member 34 acts as a resistor to prevent the brown rice from scattering, and by providing the slit 34a, the brown rice leaks and only foreign matter and the like are discharged beyond the slit 34a. Convex lines 34b are formed in several places on the plate member 34, and are appropriately inserted and fixed in the mesh 31b formed by the punching holes of the foreign matter removing and sorting net 31a. In addition to being simple in construction, there is no gap between the edge portion of the plate member 34 and the upper surface of the foreign matter removal sorting net 31a, and foreign matter and the like can be reliably discharged. Further, the structure is such that no punching hole is formed in the foreign matter removal sorting net 31a at the joint portion between the two. As a result, even if foreign matter or the like is returned to the joining portion without climbing the plate member 34, there is no risk of leakage from the mesh. On the other hand, a punching hole 31c is formed at a position close to the partition plate 35 that regulates the discharge of brown rice leaking from the slit 34a on the plate member 34 side. As a result, the brown rice shielded by the partition plate 35 can be leaked downward.
