A charge-type rice milling facility according to an embodiment of the present invention will be described.

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

A building T is partitioned by a partition wall 1 into a guest room K for users to go in and out and a machine room M in which each device is installed. In this embodiment, the passenger compartment K side is called the front, and the machine room M side is called the rear.

In the machine room M, there are a grain hoisting machine 3 for hoisting the brown rice thrown into the feeding hopper 2 by the user, a stone removing machine 4 for removing stones mixed in the brown rice, and a second machine for hoisting the brown rice from the stone removing machine 4. It is equipped with a grain raising machine 3a and a rice milling machine 5 for milling brown rice.

A switching valve 21 is provided on the discharge side of the grain raising machine 3, and brown rice is supplied to either the side of the destoner 4 or the side of the brown rice return port 22 on the input hopper 2. - 特許庁Unpolished rice can be returned to the top of the input surface of the input hopper 2 through the unpolished rice return cylinder 23 to the unpolished rice return port 22 .

On the guest room K side, there is an input hopper 2 for inputting brown rice brought by the user, an opening/closing door 6 for closing/opening the input port of the input hopper 2, and a polishing machine for storing polished rice polished by the rice milling machine 5. A polished rice tank 7, a control panel 8 operated by a user, and a lifting device 9, which will be described later, are provided. In addition, a human detection sensor 10 is provided to detect the presence or absence of a person (user) in the guest room K.

The operation panel 8 is provided with a polishing degree selection switch 11 for selecting the degree of polishing to be polished, a charge input port 19 for inserting a charge, and an elevation switch 12 for raising and lowering the lifting device 9 . The lift switch 12 includes a lift switch 12a and a fall switch 12b. 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 through the grain raising machine 3 and the brown rice return cylinder 23. It consists of

FIG. 1 shows a state in which the opening/closing door 6 is open and the brown rice in the bag h can be thrown into the feeding hopper 2. As shown in FIG.

A brown rice presence/absence detection sensor 13 for detecting whether or not there is unpolished rice in the charging hopper 2 is provided below the charging hopper 2 .

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

A lifting device 9 is provided in front of the charging hopper 2 . The lifting device 9 raises and lowers the mounting table 14 on which the bag h containing brown rice brought by the user is mounted, the weighing scale 15 for detecting the weight of the bag h mounted on the mounting table 14, and the mounting table 14. It includes an elevator 16 , a support 17 that supports the lower part of the elevator 16 , and a resin protective cover 18 that covers the periphery of the elevator 16 .

The elevator 16 is composed of 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 an electric motor 16m into linear motion. The X-shaped link portion 16a has its upper end connected to the mounting table 14 and its lower end connected to the support 17 as appropriate. 14 is constructed so that it can move up and down while its mounting surface remains horizontal. The cylinder base of the electric cylinder 16b is connected to the support base 17a provided on the support 17, and the piston tip of the electric cylinder 16b is connected to the bottom of the mounting table 14 using the reinforcing frame 14a. The electric cylinder 16b is extended by the forward rotation of the electric motor 16m and shortened by the reverse rotation, thereby moving the mounting table 14 up and down. While the lift switch 12a is turned on, the electric motor 16m is rotated forward to raise the mounting table 14 to an arbitrary height. It descends.

The protective cover 18 will be described in detail. In the illustrated example, four stages of cover members are configured such that the upper cover member overlaps the lower cover member in sequence. Among the cover members, the uppermost cover member 18u has a box-like shape with an opening facing downward so that the mounting table 14 can be mounted thereon, and is reinforced by a reinforcing frame 14a. 17 and is integrated with the support base 17 to form a box-like shape with an upward opening, and the support base 17a is contained therein. Between the lowermost cover member 18d and the uppermost cover member 18u, a plurality of intermediate cover members, two in the illustrated example, a first intermediate cover member 18m1 and a second intermediate cover member 18m2, are provided.

Here, regarding the interlocking structure of the protective cover members 18, the pin members 29m1 provided on the first intermediate cover member 18m1 are fitted into the longitudinally elongated holes 28d of the lowermost cover member 18d and connected. The pin member 29m2 provided on the second intermediate cover member 18m2 is fitted into the vertically elongated hole 28m1 of the second intermediate cover member 18m2 to connect it. are connected together.

As the X-shaped link portion 16a descends, the first intermediate cover member 18m1 overlaps the fixed lowermost stage cover member 18d and then the first intermediate cover member 18m1. The second intermediate cover member 18m2 is overlapped on the outside, and then the uppermost cover member 18u is overlapped on the outermost side of the second intermediate cover member 18m2. Conversely, as the X-shaped link portion 16a rises, the uppermost cover member 18u rises, followed by the second intermediate cover member 18m2 and the first intermediate cover member 18m1. When the pin member 29 reaches the upper end of the vertically elongated hole 28 during the upward movement, the cover member 18 on the lower side acts in the direction of lifting the entire cover member 18 .

Since the first intermediate cover member 18m1 and the second intermediate cover member 18m2 are intended for the safety of the users standing in the cabin K, they are not necessary on the side of the building side wall or the partition member from the machine room. It has a front side F facing the user and a lateral side S, and is formed in an L shape in plan view. Further, the linking structure of the vertically elongated hole 28 and the pin member 29 can be provided at a plurality of locations on the protective cover 28 to ensure stability during operation. For example, three locations are provided on the front side F and two locations are provided on one lateral side S.

The pin member 29 has a detachable structure, for example, made up of a bolt and a nut. Therefore, the first intermediate cover member 18m1 and the second intermediate cover member 18m2 can be removed individually even when the mounting table 14 is in the raised position, and inspection and repair from the side can be performed. When the inside is to be visually inspected, for example, the first intermediate cover member 18m1 and the second intermediate cover member 18m2 are supported from below 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 done by lifting upward along the longitudinal hole 28.

Next, a description will be given of smooth operation means for smoothing the sliding that accompanies the overlap and separation of the cover members. When the pin member 29 is mounted on the cover member 18 , a resin spacer 26 is provided on the pin member 29 side in order to properly secure the distance from the mating vertically elongated hole 28 . With this configuration, the pin member 29 can be smoothly moved along the elongated hole 28 . Reference numerals in the drawing match those of the pin member 29 . Since it is made of resin, the friction of the contact surface with the cover member can be reduced and the sliding can be performed smoothly. The outer shape of the resin spacer 26 is arbitrary, but if it is in the form of a ring-shaped collar, smoother operation can be achieved.

The support 17 is provided movably along a rail member 27 installed on the floor of the cabin K. As shown in FIG. The rail member 27 is laid between the front position of the input hopper 2 (the solid line in FIG. 1) and the front position of the milled rice tank 7 (the same phantom line). It is movable between the front position of the polished rice tank 7 and the front position. The rail member 27 is composed of two L-shaped elongated members arranged at equal intervals, and is configured such that idle rollers 17f provided at the bottom of the support 17 roll on the horizontal portion of the L-shaped rail member 27. , and the rail member 27 and the roller 17f constitute a hand-push type traveling means. It should be noted that the user can directly push and pull the lifting device 9 and the brown rice filling bag h to stop at an arbitrary position for reciprocating movement along the rail member 27 . An appropriate braking mechanism may be configured to ensure the stop.

Next, the rice polishing operation will be described with reference to FIG. First, the case where about 30 kg of unpolished rice is brought and 300 yen is invested to polish the rice, which is the most frequent case, will be described.

The user prepares a bag h (for example, 30 kg) containing unpolished rice brought by him and enters the guest room K. When the fee detection sensor 20 detects that a fee (for example, 300 yen) has been inserted into the fee input port 19 (S101), the opening/closing door 6 is opened (S102) so that brown rice can be input into the input port of the input hopper 2. Become. After the fee is charged, the user places the bag h on the placing table 14 at the initial position, that is, the lowered position (S103), and turns on the lift switch 12a to raise the placing table 14 of the lifting device 9 (S104). The weight is detected by the weighing scale 15 and displayed on the display screen 25 of the operation panel 8 . At this time, when the weighing scale 15 detects a weight within the set range (for example, 10 kg or more and less than 40 kg) (S105), the electric motor 16m is driven to rotate forward, and the mounting table 14 becomes the loading surface of the loading hopper 2. It rises to substantially the same height (S106, S107). Alternatively, after the charge is inserted, the mounting table 14 may be raised by automatically driving the electric motor 16m in the normal direction without using the raise switch 12a. The user puts the brown rice in the bag h into the feeding hopper 2 (S108).

If the determination in S105 is NO, that is, if the weighing scale 15 is out of the set range or if the weight is not detected, the lifting of the lifting device 9 is regulated, and the display screen 25 displays to that effect to issue an alarm (S109, S110). The case where the weight is not detected means that the user lifts the bag h from the outside of the lifting device 9 and throws it into the feeding hopper 2. In such a case, it is not necessary to drive the lifting device 9. Moreover, it is not preferable to raise the lifting device 9 from the safety point of view. In addition, when the weight exceeds the set range (40 kg or more), it may be determined that the user is on the mounting table 14. In such a case, it is preferable to raise the lifting device 9 from the safety point of view. because there is no The weight detected by the weighing scale 15 may not be displayed on the display screen 25, but may be used as a criterion for safety.

When the user selects the polishing degree selection switch 11 (S111), each operation part is driven and the rice polishing operation (normal operation mode) is started (S113, S114). The rice polishing operation continues for a time corresponding to the charged fee (S118), and when the unpolished rice presence/absence detection sensor 13 detects no unpolished rice during the rice polishing operation (S119), the leftover rice in the rice milling machine 5 is polished (remaining rice processing). operation mode) and finish the rice polishing operation (S120 to S122).

By the way, when there is no operation of the polishing degree setting switch 11 in the above S111, a notification to prompt the setting is made (S112). Further, during the rice polishing operation (S114) in the normal operation mode, the electric motor 16m of the lifting device 9 is reversely output to lower the mounting table 14 (S115, S116). This reverse rotation output is automatically output at a predetermined timing after the start of the rice polishing operation. After the mounting table 14 is lowered, it is manually moved along the rail member 27 to be positioned in front of the polished rice tank 7 (S117).

As described above, when the execution of the residual rice processing operation mode is completed, each operating unit is output to stop, and the rice polishing operation is completed (S121, S122). The user puts the polished rice, which has been polished by the rice polishing machine 5 and stored in the polished rice tank 7, into the bag h he brought and takes it home. By the way, while the bag h is placed on the mounting table 14 of the lifting device 9, the shutter of the polished rice tank 7 is opened to store the polished rice in the bag h (S123, S124). If the bag h interferes with the lifting of the mounting table 14 after the storage is completed, the lifting device 9 and the bag h for storing the polished rice are appropriately moved to a position away from the front of the polished rice tank 7 (S125). The mounting table 14 is raised. That is, by turning on the lift switch 12a and driving the electric motor 16m forward, the mounting table 14 is lifted (S126 to S128). The user can hold the raised polished rice storage bag h with both hands and take it out of the rice polishing equipment (S129). Then, when the lowering switch 12b is turned on, the mounting table 14 is lowered (S130 to S132).

If the determination in S118 is NO, it means that there is still brown rice remaining even after the operation time for the input charge has passed, so that the charge has run out. ' is displayed (S133, S134). Then, when the additional charge is entered (S135), the process returns to S113 to restart the rice polishing operation. On the other hand, when the input of the additional charge cannot be recognized in S135, the switching valve 21 is switched, and the unpolished rice return switch 24 is operated to recover the unpolished rice from the return port 22 (S136, S137).

When the human detection sensor 10 detects that there is no one after the rice polishing operation is finished, the opening/closing door 6 is closed (S138, S139).
As described above, the lifting device 9 is configured to be able to place the bag h containing the polished rice in the polished rice tank 7, and the lifting device 9 moves to an arbitrary position along the rail member 27 to carry the bag for carrying out. When lifting, the bag h on the mounting table 14 at the raised position can be lifted, and the burden of lifting the bag h on the floor surface can be reduced, and the bag h containing the milled rice can be easily handled.

As described above, by constructing the lifting device 9 until the user brings back the polished rice after polishing the brought-in brown rice, the labor for lifting the bag filled with the brown rice or the polished rice can be reduced. In addition, when the user is working in the cabin K, the protective cover 18 of the lifting device 9 prevents accidents due to entanglement of fingers or clothes by driving the lift 16 of the lifting device 9, thereby ensuring safety.

Next, the improved lifting operation of the lifting device based on the determination of the presence or absence of the waiting bag will be described with reference to FIG. 10 .

When the user's charge is detected, the device power is turned on, and detection signals from sensors and switches of each part of the device are input (S201 to 203). First, the cleaning mode is started (S204), and approximately at the same time, the electric motor 16m is driven forward to raise the mounting table 14 (S205, S206). ” is announced by voice (S207). After several seconds, the cleaning mode ends (S208), and the open/close door 6 is opened (S209). The cleaning mode is a configuration in which each part is driven before the rice polishing operation and mainly the remaining rice on the conveying path is discharged from the foreign matter removal part of the destoner 4 to the outside of the machine, and is executed over several seconds.

The forward rotation of the electric motor 16m started in S205 is once stopped (S210), and the mounting table 14 stops rising at an initial set height position which is a short distance from the floor and a low height (S211). Here, the initial setting height is performed by preset time management from the start of forward rotation of the electric motor 16m in S205, and is set at a height of, for example, 10 cm to 20 cm from the floor. indicates that the mounting table 14 will rise.

After the temporary stop of the mounting table 14 in S210 and S211, the electric motor 16m continues to rotate forward (S212), and the mounting table 14 reaches the highest position (S213). The user puts in brown rice and presses the polishing degree selection switch 11 to select the degree of polishing (S214, S215). By this selection of the degree of polishing, each part of the operation is turned on to enter the starting state.

When the rice polishing operation is started (S216), every time T elapses, in other words, every period T (S217, S218), the standby bag presence/absence determination mode is executed (S219). Here, the standby bag refers to a bag hw that the same user brings in a plurality of brown rice bags h and is waiting in addition to the bag h currently being processed. Based on actions, it is assumed that there is a waiting bag hw (S220).

If it is determined in S220 that there is no waiting bag hw, the normal operation ending process is started. That is, when it is determined that there is no unpolished rice in the charging hopper 2 (S221), the remaining rice processing operation mode is executed (S222), and a command to stop the rice polishing operation is output (S223). After that, the opening/closing door 6 is closed (S224), the electric motor 16m is reversely output, and the mounting table 14 is returned to the lowest position (S225, S226). If it is determined in S221 that there is unpolished rice, it is further determined whether or not the operating time for the input fee has elapsed (S227), and if the operating time has elapsed (Yes), the rice polishing operation is stopped ( S223), and if the operating time has not elapsed, the process returns to S216.

Now, if it is determined that the waiting bag hw is present in the presence/absence determination of the waiting bag hw in S220, the waiting bag hw is raised by the following procedure. That is, first, a reverse rotation command is output to the electric motor 16m to lower the mounting table 14 at the highest position, and during that time, the effect of the lowering is announced by voice (S228 to S230). Here, the user puts the standby bag hw on the mounting table 14 and turns on the lift switch 12a (S231). Then, the mounting table 14 can be raised to the highest position by the forward rotation output of the electric motor 16m (S232, S233).

The electric motor 16m that constitutes the elevator 16 is configured so that the number of revolutions thereof can be changed according to the supplied current. Therefore, variable speed control can be performed to vary the lifting and lowering speeds of the mounting table 14 . For this reason, the lifting speed and the lowering speed of the mounting table 14 can be varied, and the speed can be changed as appropriate during the lifting process. It can also be slowed down again. That is, the initial speed from the lowest position and the ending speed from just before the highest position to the end of the rise are slowed down. With this configuration, the bag h on the mounting table 14 can be prevented from falling over. In the descending process, the robot is descended at a constant high speed (either the maximum speed or any lower speed) to reduce time loss.

Next, execution of the standby bag presence/absence determination mode will be described with reference to FIG.

First, when this mode is entered, the elevation of the mounting table 14 by the elevation switch 12 is normally restricted, but the elevation restriction by the elevation switch 12 is released (S301). This is to cancel the operation based on the ON state of the lift switch 12a in S232. In S234, the regulation state is restored again.

Then, each switch and sensor information is input (S302), and it is determined whether or not an additional charge is charged (S303). If it is determined that there is an additional charge, it is determined that there is a waiting bag hw (S304). In addition, it is determined whether or not the operation time (so-called standard operation time) for consuming the amount of money required to process a standard bag of brown rice (for example, 30 kg), such as 300 yen, has elapsed. has passed and it is further determined that there is a balance in the inserted amount (S305, S306), then in S304 it is determined that there is a "waiting bag hw". In other words, the fact that the fee is more than the amount required for this standard operating time is because it is predicted that there will be carry-on bags other than the standard bags. Furthermore, by separately providing the waiting bag switch 35 and turning it on, or by turning on the lowering switch 12b (S307), it is determined that "there is a waiting bag hw". Turning on the waiting bag switch 35 and turning on the lowering switch 12b is caused by the user's behavior in anticipation of "there is a waiting bag hw".

If all of the following conditions are met: no additional charge, no remaining money after the standard operating time has passed, and no waiting bag switch and lowering switch 12b ON, it is determined that there is no waiting bag (S308).

As described above, when it is determined that there is a standby bag by executing the standby bag presence/absence determination mode, the mounting table 14 is automatically lowered to facilitate the work of placing the standby bag hw on the mounting table 14 .

A supplementary description will be given of the lifting operation of the lifting device 9 when the rice polishing operation is stopped due to the expiration of the charge (S119) after the operating time corresponding to the charge in the embodiment of FIG. 9 has elapsed.

When the brown rice presence/absence detection sensor 13 detects the presence of brown rice, but the rice polishing operation is stopped, there are three cases as follows. The first is when an additional fee is charged (S135). In this case, the rice polishing operation is started (restarted) as shown in FIG. The second case is that the amount of unpolished rice remaining in the input hopper 2 is small, or the user returns without noticing the remaining unpolished rice. In this case, when the human detection sensor 10 detects that there is no one in the guest room K (S138), the opening/closing door 6 is lowered and closed. In addition, the roller 17f on the rail member 27 of the lifting device 9 is replaced by a driven roller 17d driven by a traveling motor instead of a hand-pressed idle roller type, and a limit roller 17f that can contact the frame portion of the support body 17 is placed at an appropriate place on the rail member 27. If a position detection sensor in the form of a switch is provided to enable the lifting device 9 to move left and right along the rail member 27 and to detect its position (automatic travel means), the travel and position by the control unit A will be realized. control becomes possible. In such a case, when the lifting device 9 (mounting table 14) is in the raised position based on the human absence determination of the human detection sensor 10, the feeding hopper 2 is automatically moved to the initial position on the front side and loaded. The mounting table 14 can be automatically lowered. Thirdly, when the unpolished rice return switch 24 is operated (S136), the switching valve 21 is switched from the de-stoner 4 side to the unpolished rice return tube 23 side, and the grain hoisting machine 3 starts driving for a predetermined time. Then, the unpolished rice in the input hopper 2 passes through the grain raising machine 3 and the unpolished rice return cylinder 23 and is returned from the unpolished rice return port 22 to the input hopper 2 side. The user receives and stores the brown rice returned in the bag h brought by him on the input hopper 2.例文帳に追加At this time, when the mounting table 14 is in the raised position on the front side of the input hopper 2, it maintains that position, and when it is at a position away from this position, it moves along the rail member 27 to lift the mounting table 14. By ascending, the bag h containing brown rice can be placed on the placing table 14 and lowered. The unpolished rice return switch 24 is continuously operated until the remaining unpolished rice is accommodated from the unpolished rice return port 22. After the unpolished rice is accommodated, the polished rice is recovered, but the procedure is the same as S121 and subsequent steps in FIG.

Here, the electric type traveling means which replaces the hand-push type using the rail member 27 and the floating roller 17f as the traveling means with the drive type roller 17d using the electric traveling motor will be described in detail with reference to the control block diagram of FIG. 4 and the time chart of FIG. explain. First, as switch information to be input to the control unit A, in addition to the human detection sensor 10, the milling degree setting switch 11, the lift switch 12, and the information of the manual running switch 32 for switching the running motor 31 between normal rotation and reverse rotation are input. Further, as various detection means information, a weight sensor (weighing scale) 15, an elevation detection sensor composed of a rise detection sensor 33u for detecting that the mounting table 14 is in the raised position and a lowering detection sensor 33d for detecting that it is in the lowered position. 33, three traveling position sensors 34a, 34b, 34c for detecting that the lifting device 9 has reached a predetermined position on the rail member 27; Of these, the first traveling position sensor 34a detects when the lifting device 9 is positioned in front of the input hopper 2 (a), and the second traveling position sensor 34b detects when the lifting device 9 is positioned in front of the milled rice tank 7. When (b), the third running position sensor 34c is located at the intermediate position between the first running position sensor 34a and the second running position sensor 34b (c). It has a configuration of a limit switch type or a reed switch type which is turned on by contacting the lifting device 9 . The position of the third running position sensor 34 is adjustable along the rail member 27 .

When the human detection sensor 10 detects a person, the power source of the device and the control section is turned on. The user places the brown rice bag h on the mounting table 14 of the lifting device 9 at the initial position, that is, at the lower position in front of the feeding hopper 2 . When the lift switch 12a of the lift switches 12 is turned on, the mounting table 14 is lifted and the lift position detection sensor 33u of the lift detection sensor 33 is turned on. A user holds the raised brown rice bag h, puts brown rice into the charging hopper 2, and operates the polishing degree setting switch 11 to carry out the rice polishing operation.

After a predetermined time t1 after the milling degree setting switch 11 is operated, the control unit A issues a table lowering output, and the electric motor 16m of the elevator 16 rotates in reverse to lower the table 14. As shown in FIG. After the set time t1 has passed, the control section A waits until the second set time t2, which is a time sufficient for the mounting table 14 to reach the lowered position, and outputs the movement of the lifting device 9. FIG. Specifically, it is a movement from the front of the feeding hopper 2 to the front of the milled rice hopper 7 , and a normal rotation command is output to the traveling motor 31 . The lifting device 9 moves along the rail member 27 and stops in front of the polished rice tank 7 . This stop output is detected by the second traveling position sensor 34b.

Now, when the rice polishing operation is completed, the polished rice storage bag h is placed under the polished rice tank 7 . Open the shutter to eject. Accordingly, the weight sensor 15 detects and displays the detection result. When the bag h containing the polished rice is completed, the lifting device 9 is shifted from the position of the polished rice tank 7 to take it out. Since movement in this direction is executed by rotating the travel motor 31 in reverse, the manual travel switch 32 is set to the reverse rotation side. When the position of the third travel position sensor 34c is reached, the travel motor 31 stops. At this position, the polished rice storage bag h is taken out. If the lift switch 12a of the lift switch 12 is operated before taking out the bag, the mounting table 14 is lifted, making it easier to take out.

When the user leaves to finish the work and the human detection sensor 10 determines that there is no one, the control unit A returns to the initial position. When this output is received, first, a mounting table descending output is issued and the mounting table 14 descends. Immediately after the descent is confirmed by the elevation detection sensor 33 , a reverse rotation command signal is output to the traveling motor 31 , and the elevation device 9 reaches the front position of the input hopper 2 . Thus, the lifting device 9 can return to the front of the input hopper 2 with the mounting table 14 at the lowered position, and waits at the initial position for the next operation. A series of steps is completed within a predetermined time t3 (FIG. 12) after the initial position return output is output, and the power supply of the device and the control section is turned off.

Based on the forward or reverse rotation output of the travel motor 31 by the travel manual switch 32 or the drive output of the travel motor 31 of the controller A, the lifting device 9 travels along the rail member 27, but the mounting table 14 of the lifting device 9 does not move. When it is not in the lowered position, that is, when the lowering detection sensor 33d is not in the ON condition, the driving output of these traveling motors 31 is regulated (NG in FIG. 12). For this reason, if the mounting table 14 is at a high position and the bag h filled with brown rice or polished rice is moved, the filling bag h may drop depending on inertia and speed, but the mounting table 14 is in the lowered position. Even if it falls, there is little fear of scattering.

Further, when the weight detected by the weighing scale 15 exceeds a predetermined value, the movement output to the traveling means is restricted. In other words, in the case of an automatic traveling device, there is a risk that the device will fall unexpectedly, and if it falls, there is a risk of damage to other objects due to the heavy weight of the device, but this can be prevented.

In the description so far, the lift switch 12 is arranged on the operation panel surface as shown in FIG. With this configuration, the presence of the opening/closing door 6 which cannot be opened until the user has inserted a fee prevents anyone other than the user from haphazardly operating the up/down switch.

Also, even if the rice milling equipment such as the rice mill 5 fails to perform the rice polishing work, if the lifting device 9 does not malfunction, the lifting switch 12 of the lifting device 9 is allowed to operate. With this configuration, it is convenient to lift the bag when taking out the unpolished rice remaining in the input hopper 2 during the rice polishing work or when taking out the bagged polished rice from the polished rice tank 7.例文帳に追加

Next, referring to FIGS. 2 and 3, a packing device for the bran produced by the rice polishing process of the rice milling machine 5 will be described.

When the rice is polished to a predetermined degree of polishing in the rice polishing machine 5 , the bran layer peeled off from the surface of the brown rice grains is sorted and separated, and the bran is removed from the rice polishing chamber of the rice polishing machine 5 . The bran removed is conveyed by a suction dust extractor, an auger lathe, or the like, and stored in a bran bag disposed on the back side of the machine room M. When the user obtains a portion of the bran pack P during such a bran removal operation, the portion of the bran removed from the rice milling machine 5 is removed from the rice bran pack by the operation of obtaining the rice bran pack P. The rice bran is supplied to the device 50, and the rice bran packing device 50 packs P by the film sheets F in predetermined amounts. The bran pack P packed in the pack P is received by the upper surface of the inclined rice bran pack chute 53 and slid down to the cabin K side.

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

In addition, the film roll F for obtaining the bran pack P is loaded in advance inside the bran pack storage chamber 52 when performing the rice polishing action, but the film roll F may decrease with use. When the film roll F needs to be replaced with a new one or replenished, a new film roll F can be loaded into a predetermined location in the bran pack storage chamber 52 to maintain the state in which the bran pack P can be formed.

The bran that leaks from the rice bran removing net of the rice mill 5 is sucked and conveyed by a blower, which is a suction dust extractor 30 , and is blown and conveyed to the cyclone 41 . Conveying cylinders 44 and 45 having spirals 43 are arranged at the upper position extending from the bran packing device 50 in the machine room M to the bran bag chamber 42 on the far side, and the bran separated by the cyclone 41 is transferred. By the rotation of the screw 43, the rice is conveyed to the rice bran bag D in the rice bran bag chamber 42, and the rice is packed in the bag D and supplied from each outlet tube 46. - 特許庁A geared motor 47 provided at one end of the conveying cylinder 44 can be switched between normal and reverse rotation by operating a rice bran extraction switch 48. is conveyed to the discharge port cylinder 49 which is visible above the rice bran packing device 50 on the partition wall 1 side. The rice bran removal switch 48 is provided on the upper part of the partition wall 1 of the guest room K so that the user can easily operate it from the guest room K.
The ceiling of the machine room M is equipped with a noise meter 37 or a vibration meter. The noise level of the sound level meter 37 is connected to the control unit A via a current converter 38 that converts the noise level into a current. Then, the drive output of each part of the rice milling machine 5 is regulated. It is possible to detect the occurrence of abnormal noise due to the wear of each part of the rotating equipment, and to prevent damage to the rotating equipment. If the sound level meter 37 is mounted on the ceiling, it is possible to prevent the sound level meter 37 itself from malfunctioning by reducing dust adhesion.

By covering the sound level meter 37 with a dustproof filter, dust can be prevented from adhering to it, so it can be installed at a lower position such as the back side of the operation panel, and abnormal noise can be detected more accurately than when installed on the ceiling. .

The conversion current value is set in two stages to improve the abnormality detection accuracy. That is, the noise-converted current value Im when the whiteness of the rice mill 5 is set to the maximum pressure and the estimated noise-converted current value Ix when the rotating equipment such as the rice mill 5 is damaged are stored in the storage unit. Note that Im and Ix may be empirical values or estimated values. When the actual noise conversion current value I exceeds the first stage current value Im and reaches the second stage current value (=Im+(Ix−Im)/2), the device is stopped. Since the current value of the second stage is set to an intermediate value between Im and Ix, it can be detected before the device is damaged. Note that the current value in the second stage is not limited to the above formula as long as it is between Im and Ix. As a countermeasure when the current value of the second stage is exceeded during the rice polishing operation and the current value is stopped, there are various countermeasures such as displaying an error at the end of rice polishing and disabling the next rice polishing.

In addition, by providing the sound level meter 37 and the vibration meter in the machine room M, a crime prevention effect can be obtained by comparing the driving state of each part such as the rice milling machine. That is, when the sound level meter 37 or the vibration meter is detected to operate in the non-driving state, the crime prevention bell 39 is sounded. It is possible to detect the vibration caused by an act such as a person breaking into the machine room M using a large tool to damage a door or a safe, and to output a sound to the crime prevention bell 39 .
