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 passenger compartment K side is referred to as a front, and the machine room M side is referred to as a rear.

In the machine room M, a grain raising machine 3 for raising 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 raising 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 to supply brown rice to either the stone removing machine 4 side or the brown rice return port 22 side on the loading hopper 2. The brown rice can be returned to the brown rice return port 22 via the brown rice return cylinder 23, and the brown rice can be returned above the charging surface of the hopper 2.

On the K side of the guest room, there is an input hopper 2 for charging 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 a user, and an elevating device 9 described later are provided. Further, 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, a fee input port 19 for charging a fee, and a lifting switch 12 capable of raising and lowering 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 charging 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.

At the lower part of 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 unit 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 a mounting table 14 on which a bag h for accommodating brown rice brought by the user is placed, a weighing scale 15 for detecting the weight of the bag h placed on the mounting table 14, and a mounting table 14. It includes an elevating tool 16, a support 17 that supports the lower part of the elevating tool 16, and a resin protective cover 18 that covers the periphery of the elevating tool 16.

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 pedestal 14 and the lower end to the support 17, and pivotally connecting the ends to each other 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 configured 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 forward 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-mentioned pedestal 14, and is reinforced by a reinforcing frame 14a. The lowermost cover member 18d is the support pedestal. 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 above, 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.

In order to form the connection as described above, as the X-shaped link portion 16a descends, 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 the purpose is 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 in a plurality of places 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 vertical 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 it can be further facilitated by using an annular collar shape.

The support 17 is movably provided along the rail member 27 installed on the floor surface of the guest room K. The rail member 27 is laid between the front position of the charging hopper 2 (solid line in FIG. 1) and the front position of the polished rice tank 7 (the virtual line), so that the elevating device 9 is exactly the front position of the charging hopper 2. It is movable to and from the front position of the white rice tank 7. The rail member 27 is composed of two L-shaped long members arranged at equal intervals, and the idler roller 17f provided at the lower part of the support 17 is rolled on the horizontal portion of the L-shaped rail member 27. The rail member 27 and the roller 17f constitute a hand-push type traveling means. The user can directly push and pull the elevating device 9 and the brown rice filling bag h to stop at an arbitrary position for reciprocating along the rail member 27. An appropriate braking mechanism may be configured to ensure stopping.

Next, the rice milling operation will be described with reference to FIG. First, we will explain the case of bringing about 30 kg of brown rice, which is the most common scene, and putting in 300 yen to polish the rice.

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 at the initial position, that is, the descending position (S103) and turns on the ascending switch 12a to raise the mounting table 14 of the elevating device 9 (S104). The weight is detected by the weight scale 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 direction 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 is out of 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 elevating device 9 and puts it into the loading hopper 2. In such a case, it is not necessary to drive the elevating device 9. Moreover, raising the elevating device 9 is not preferable from the viewpoint of safety. Further, if the weight 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 (S118) and the brown rice presence / absence detection sensor 13 detects the absence of brown rice during the rice milling operation (S119), the residual rice in the rice milling machine 5 is milled (residual rice operation). Mode) to end the rice milling operation (S120 to S122).

By the way, when the whiteness setting switch 11 is not operated in S111, a notification prompting the setting is given (S112). Further, during the rice milling operation (S114) in the normal operation mode, the electric motor 16m of the elevating device 9 is reversely output to lower the mounting table 14 (S115, S116). It should be noted that this reverse output is automatically output at a predetermined timing after the start of rice milling operation. After the mounting table 14 is lowered, it is manually moved along the rail member 27 to be in the front position of the polished rice tank 7 (S117).

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 (S121, S122). The user brings the polished rice, which has been milled by the rice milling machine 5 and stored in the polished rice tank 7, into a bag h and takes it home.

By the way, the bag h is placed on the mounting table 14 of the elevating device 9 and 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 ascent of the mounting table 14 after the storage is completed, the elevating device 9 and the polished rice storage bag h are appropriately moved to a position off the front of the polished rice tank 7 (S125), and at that position. Ascend the mounting table 14. That is, the mounting table 14 is raised by turning on the rise switch 12a and driving the electric motor 16m in the forward direction (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 facility (S129). Then, when the lowering switch 12b is turned on, the mounting table 14 is lowered (S130 to S132).

The determination of NO in S118 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 (S133, S134). Then, when an additional charge is charged (S135), the rice milling operation is resumed by returning to S113. On the other hand, when the input of the additional charge cannot be recognized in S135, 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 (S136, S137).

When the human detection sensor 10 detects that no one is present after the rice milling operation is completed, the open / close door 6 is closed (S138, S139).
As described above, the elevating device 9 has a configuration in which the bag h for accommodating the polished rice in the polished rice tank 7 can be placed, and the elevating device 9 moves to an arbitrary position along the rail member 27 and carries it for taking out. When raising the bag h, the bag h of the mounting table 14 in the raised position may be lifted, the burden of lifting the bag h on the floor surface can be reduced, and the bag h containing polished rice can be easily handled.

As described above, the labor of lifting the brown rice or the bag filled with the polished 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 driving of the elevating tool 16 of the elevating device 9 prevents accidents such as finger entanglement and clothing entanglement, which is safe.

Next, another protective cover 35 provided on the side surface of the elevating device 9 will be described with reference to FIG. The screens 35F and 35S are provided on the front side F and the lateral side S of the elevating device 9 so as to be windable. It is fixedly connected to the member 36, and the lower end side is connected to the winding means 37F and 37S provided on the support 17. Here, the winding means 37F and 37S are configured to sequentially wind around the winding shafts 38F and 38S by the urging force of a spring (not shown) that incorporates the screens 35F and 35S by lowering the elevating device 9. There is. On the contrary, as the elevating device 9 rises, the screens 35F and 35S are sequentially extended to surround the front side F and the lateral side S of the elevating device 9. If the screen 35F on the front side F is extended so as to cover the front end edge of the screen 35S on the side S, the safety of the user can be further ensured. Further, by shifting the screen 35F on the front side F toward the screen 35S on the side S in a plan view, it is possible to further prevent the entry of fingers.

When the elevating device 9 is inspected or repaired, the upper ends of the screens 35F and 35S can be easily removed from the support member 36 regardless of the raised position of the mounting table 14. If the upper ends of the screens 35F and 35S are removed from the support member 36, they may be caught in the winding means 37F and 37S. To prevent this, the screens 35F and 35S have a winding restricting tool 39. Is provided. Specifically, iron plates 39F and 39S as winding regulators are appropriately attached near the upper ends of the screens 35F and 35S. The iron plates 39F and 39S may be provided on the entire widths of the screens 35F and 35S, or may be partially provided. When the screens 35F and 35S are wound around the winding shafts 38F and 38S of the winding means 37F and 37S due to the presence of the iron plates 39F and 39S, the winding means 37F and 37S are wound by the presence of the iron plates 39F and 39S. The iron plates 39F and 39S are trapped in the mouths 40F and 40S to restrict the entrainment of the screens 35F and 35S. Therefore, when the screens 35F and 35S are attached to the support member 36 again, the ends of the screens 35F and 35S can be easily gripped and the work can be facilitated.

Next, the operation of the elevating 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 for 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 ascending / descending operation is restricted.

As a case of restricting the descending 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 in terms of 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 rising switch 12a. Also in this case, if 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 raising the brown rice to the ascending position and then charging the brown rice into the charging hopper 2, the same procedure 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, the ascending / descending operation of the elevating device 9 in the case of 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 cabin 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 milling degree selection switch 11, the mounting table 14 may be controlled to be lowered to the initial position. In this case, if there is a bag h containing the next 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 (S119) after the operation time corresponding to the charge according to the embodiment of FIG. 7 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 (S135). 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 (S138), the opening / closing door 6 descends and closes. In addition, the elevating device 9 is replaced with a roller 17f on the rail member 27 from a hand-pushed floating roller type to a drive type roller 17d by a traveling motor, and a limit capable of contacting the frame portion of the support 17 at an appropriate position on the rail member 27. If a position detection sensor in the form of a switch is provided to enable left-right switching traveling along the rail member 27 of the elevating device 9 and the position can be detected (automatic traveling means), traveling and position by the control unit A are provided. Control is possible. In such a case, if the elevating device 9 (mounting table 14) is in the raised position based on the person absence determination of the person detection sensor 10, it is automatically moved to the initial position of the front position of the loading hopper 2 and mounted. The platform 14 can be automatically lowered. Third, when the brown rice return switch 24 is operated (S136), the switching valve 21 switches from the stone removing machine 4 side to the brown rice returning 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 frying 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 on the front side of the loading hopper 2, the position is maintained, and if the position is far from this position, the mounting table 14 is moved along the rail member 27 to move the mounting table 14. By ascending, the bag h containing brown rice can be placed on the mounting table 14 and 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 polished is collected, but the procedure is the same as that after S121 in FIG.

Here, as a traveling means, the electric traveling means in which the hand-push type by the rail member 27 and the floating roller 17f is replaced with the drive type roller 17d by the electric traveling motor is described in detail based on the control block diagram of FIG. 4 and the time chart of FIG. explain. First, as the switch information to be input to the control unit A, in addition to the person detection sensor 10, the whitening degree setting switch 11, and the elevating switch 12, the traveling manual switch 32 information for switching the traveling motor 31 to forward rotation or reverse rotation is input. Further, as various detection means information, an elevating detection sensor including a weight sensor (weigh scale) 15, an ascending detection sensor 33u for detecting that the mounting table 14 is in the ascending position, and a descent detecting sensor 33d for detecting that the mounting table 14 is in the descending position. 33, it has three traveling position sensors 34a, 34b, 34c for detecting that the elevating device 9 has reached a predetermined position of the rail member 27. Of these, in the first traveling position sensor 34a, when the elevating device 9 is located in front of the loading hopper 2 (a), in the second traveling position sensor 34b, the elevating device 9 is located in front of the polished rice tank 7. When (b), the third traveling position sensor 34c is appropriately arranged in the fixing member in the cabin K so as to detect when it is at an intermediate position between the first traveling position sensor 34a and the second traveling position sensor 34b (c). It is configured as a limit switch or a reed switch that is installed and is turned on when it comes into contact with the elevating device 9. The position of the third traveling position sensor 34 can be adjusted along the rail member 27.

When the human detection sensor 10 detects a person, the device and the control unit main power are turned on. The user puts the brown rice bag h on the mounting table 14 of the elevating device 9 in the initial position, that is, in front of the loading hopper 2 and in the descending position. Then, when the ascending switch 12a of the elevating switch 12 is turned on, the mounting table 14 ascends and turns on the ascending position detection sensor 33u of the elevating detection sensor 33. The user takes the raised brown rice bag h, puts the brown rice in the throwing hopper 2, and operates the whitening degree setting switch 11 to perform the rice milling operation.

After a predetermined time t1 after the operation of the whiteness setting switch 11, a mounting table lowering output is emitted from the control unit A, and the electric motor 16m of the elevating tool 16 reverses and lowers the mounting table 14. After the elapse of the set time t1, the control unit A waits for the elapse of the second set time t2, which is sufficient time to reach the descending position of the mounting table 14, and the control unit A moves and outputs the elevating device 9. Specifically, it is a movement from the front of the input hopper 2 to the front of the polished rice hopper 7, and a forward rotation command is output to the traveling motor 31. The elevating device 9 moves along the rail member 27 and stops in front of the polished rice tank 7. This stop output is based on the detection of the second traveling position sensor 34b.

When the rice milling operation is completed, the polished rice storage bag h is viewed below the polished rice tank 7. At this time, the bag h is placed on the mounting table 14 of the elevating device 9 that stands by at the lowering position, and the polished rice tank 7 is placed. Open the shutter and eject. Along with this, the weight sensor 15 detects and displays and outputs the detection result. When the storage of the polished rice bag h is completed, the elevating device 9 is displaced from the position of the polished rice tank 7 and taken out. Therefore, the traveling manual switch 32 is operated to move the polished rice to the charging hopper 2 side. Since the movement in this direction is executed by reversing the traveling motor 31, the traveling manual switch 32 is set to the reversing side. When the third traveling position sensor 34c position is reached, the traveling motor 31 stops. At this position, the polished rice storage bag h is taken out, but if the ascending switch 12a of the elevating switch 12 is operated before taking out, the mounting table 14 is raised and it becomes easy to take out.

In FIG. 12, a mounting table sliding means 55 is provided between the mounting table 14 and the uppermost cover member 18u, and the polished rice storage bag h is viewed below the polished rice tank 7 for convenience. The mounting table slide means 55 is composed of a slide mechanism 58 provided with left and right rails 56 on the cover member 18u side, left and right multiple rollers 57 on the mounting table 14 side, and an electric cylinder 59 that expands and contracts by forward and reverse rotation of the electric motor 59m. Become. The cylinder side base of the electric cylinder 59 is connected to the cover member 18u, and the tip on the piston side is connected to the mounting table 14. The electric cylinder 59 is extended by the forward rotation output to the electric motor 59m, and the mounting table 14 is connected to the rail 56. The electric cylinder 59 is shortened by the reverse output to the electric motor 59m, and the mounting table 14 is slid back along the rail 56. Here, the slide forward means a horizontal movement from the upper surface of the elevating device 9 toward the partition wall 1, that is, a horizontal movement toward the lower space of the polished rice tank 7, and the slide backward means the opposite. The forward / reverse output of the electric motor 59m depends on the operation of the slide switch 60. The slide switch 60 is, for example, in the form of a push button switch and has a momentary function, and is provided with a forward switch 60f and a reverse switch 60r. (Fig. 1).

Here, the mounting table slide control will be described with reference to FIG. When the rice milling operation is completed, the slide state of the mounting table 14 is input, and it is determined whether it is in the storage position or the forward position (S201 to S203). When the slide is in the forward position, an alarm is output and the mounting table 14 is retracted and slid by operating the backward switch 60r (S204 to S206). Further, when the vehicle is in the storage position in S203, the process proceeds to the next step, the second traveling position sensor 34b is turned on, and it is determined whether or not the elevating device 9 is in the position facing the polished rice tank 7. S207, S208). Then, when the rice is in a position facing the polished rice tank 7, the forward switch 60f is turned on (S209). The estimated polished rice weight is calculated by the input amount and the weight scale provided in the input hopper 2 (S210), and when the estimated polished rice weight is equal to or more than the predetermined weight G (for example, 20 kg), the lower switch 12b is turned on and the mounting table 14 is turned on. Is the lowest (S211 and S212). When the weight is less than the predetermined weight G (for example, 20 kg) in S210, the ascending switch 12a and the descending switch 12b are turned on to set the elevating device 9 to the predetermined intermediate position (S213, S214). The mounting table 14 can slide forward only in the states of S212 and S214 (S215). If NO in S208, the elevating device 9 is moved to the opposite position of the polished rice tank 7 (S216). The polished rice storage bag is set on the mounting table 14 that lowers the elevating device 9 and slides forward in the lowered state as in S212, or on the mounting table 14 that adjusts the height by the elevating device 9 and slides forward as in S214. (S217). Then, when the shutter of the polished rice tank 7 is opened, the filling of the polished rice starts (S218). When the discharged of polished rice is completed (S219), the retreat switch 60r is turned on and the mounting table 14 is stored and slid (S220, S221).

Then, the mounting table 14 is raised to take out the polished rice storage bag (S222, S223). When the estimated weight of the polished rice is the predetermined weight G (for example, 20 kg) or more, the height of the mounting table 14 is increased from the lowest position, but when the weight is less than the predetermined weight G, the weight is increased from the intermediate position. ..

Conventionally, the polished rice storage bag was placed directly on the floor below the polished rice tank 7 to store the discharged polished rice, so even if it is at the bottom, the filled polished rice storage bag is filled after the storage is completed. Had to be moved to the mounting table 14 side, but by incorporating the mounting table slide control as described above, the mounting table 14 can be slid forward to set the polished rice storage bag, and after filling the polished rice. The storage bag can be put into a storage state by sliding the mounting table 14 back, and the bag filled with polished rice can be easily placed in the upper part of the elevating device 9. Then, when it is determined that the filling amount is large and the weight is heavier than 20 kg, the mounting table 14 is set to the lowest position in S212, so that the upper space of the mounting table 14 can be secured. Since the mounting table 14 is in a cantilevered posture when the mounting table 14 slides forward, if a block-shaped spacer 61 is provided in the space between the lower portion of the mounting table 14 and the floor surface, the mounting table 14 can be stably supported. Can be done.

When the weight of the polished rice is less than 20 kg and the weight is relatively light, the mounting table 14 is set at a predetermined intermediate position in S214. Since it is relatively lightweight, it can satisfactorily support the bag during and after filling of polished rice even if the mounting table 14 is in a high-holding support state, and when it slides back in that position, the mounting table 14 becomes a high position. Easy to take out. Since the mounting table 14 is provided with a weight scale 15, it is possible to detect not only the input brown rice but also the polished rice filling weight. When the filling weight of the polished rice storage bag exceeds the predetermined weight G (20 kg), the shutter of the polished rice tank 7 is temporarily closed to interrupt the filling of the polished rice, and the mounting table 14 is set to the lowest position by the elevating device 9. After that, the shutter of the polished rice tank 7 may be opened again to continue filling. With this configuration, even if the detection accuracy of the estimated polished rice weight is not high, it is possible to avoid filling the mounting table 14 at the intermediate position with polished rice exceeding the safe range of 20 kg, and it is possible to prevent damage to the mounting table 14 and related equipment. ..

The user leaves to finish the work, and when the person detection sensor 10 determines that there is no person, the control unit A outputs a return to the initial position. Upon receiving this output, the mounting table lowering output is first output and the mounting table 14 is lowered. Immediately after the descent is confirmed by the elevating detection sensor 33, a reverse rotation command signal is output to the traveling motor 31, and the elevating device 9 reaches the position in front of the loading hopper 2. In this way, the elevating device 9 can return to the front of the loading hopper 2 at the lowering position of the mounting table 14, and stands by at the initial position for the next work. A series of steps are completed within a predetermined time t3 after the initial position return output is output, and the power supply of the device and the control unit is turned off.

The elevating device 9 moves and travels along the rail member 27 based on the forward or reverse rotation output of the traveling motor 31 by the traveling manual switch 32 or the traveling motor 31 drive output of the control unit A, but the mounting base 14 of the elevating device 9 moves. When the vehicle is not in the descending position, that is, when the descending detection sensor 33d is not in the ON condition, the drive outputs of these traveling motors 31 are regulated (NG in FIG. 8). Therefore, if the mounting table 14 is in a high position and the brown rice or polished rice filling bag h is moved, the filling bag h may fall depending on the inertia and speed, but the mounting table 14 is in the lowered position. Even if it falls, there is little risk of scattering.

Further, when the weight detected by the weight scale 15 exceeds a predetermined value, the movement output to the traveling means is regulated. That is, in the case of an automatic traveling device, there is a risk of accidentally falling, and if it falls, there is a risk of damage to other objects due to heavy objects, but these can be prevented.

Next, a case where the weight of the 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 milling machine 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 elevating 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, a 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 rice into packs 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 slanted 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 previously loaded in the bran pack storage chamber 52 in order to perform the rice milling action, but the film roll F may be reduced by use. When the film roll F needs to be replaced or replenished with a new one, the 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. The transport cylinders 44 and 45 having the spiral 43 are arranged at the 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 spiral 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.
