  Based on the drawings, an automatic rice milling facility for bringing raw rice brown rice into rice milling is partitioned into a building 7 by a partition wall 8, and is divided into an operation room 9 and a machine room 11 in which a rice milling apparatus 10 and the like are installed. A user who uses this automatic rice milling facility enters from the door opening 12 of the operation room 9, brings in the brown rice to be polished, supplies it to the brown rice hopper 1 provided on the partition wall 8, and supplies the rice polished by the rice milling apparatus 10. This is a configuration to be performed. The polished white rice is taken out from the white rice hopper 13.

  The partition wall 8 is provided with an operation panel 14 in the center, and comprises a brown rice inlet 2 on the front side of the left and right side brown rice hopper 1 and a closing shutter 3 that can open and close the inlet 2. It is the structure which arrange | positions the white rice hopper 13 grade | etc., On the left-right other side.

  In the vicinity of the partition wall 8 side of the machine room 11, the brown rice hopper 1 is provided on the left side, and the white rice hopper 13 is provided on the right side. In this machine room 11, there are arranged a stone extraction / separation device 15 that receives the unpolished rice fed and transported from the brown rice hopper 1 and sorts the stone, and a rice milling device 10 that receives the unpolished brown rice and polishes it. A first cerealing device 16 is disposed between the unpolished rice hopper 1 and the stone extraction device 15, and a second cerealing device 17 is disposed between the stone extraction device 15 and the rice milling device 10. The white rice polished by the rice milling apparatus 10 can be taken out to the white rice hopper 13.

  A cyclone 18 is disposed at a high position at the rear of the machine room 11, and the lower opening of the cyclone 18 is seen in the left and right intermediate portion of the soot transfer device 19. The intake port of the cyclone 18 is configured so as to be able to suck in the soot that is carried along the airflow as appropriate. Soot that does not ride on the swirling flow of the cyclone 18 is discharged from the lower intake port and is guided to be discharged into the soot transporting device 19. The rice bran transfer device 19 is provided with a transfer spiral 19b that can be linked forward and backward with the transfer cylinder 19a, and the transfer spiral 19b rotates forward by the forward rotation interlocking of the drive motor 20, and the rice bran discharged from the transfer rod 19a is removed. It moves toward the bag pack device 21 arranged at the rear. Further, when the drive motor 20 is reversely rotated, the transfer spiral 19b is reversely rotated so that the bag discharged to the transfer rod 19a is discharged and guided to the large bag 22.

  The bag pack device 21 will be described. While the thin film F wound around the roller 26 is fed out and formed into a cylindrical shape, the upper and lower vertical overlapping portions and the bottom portion are sealed by the welding means 27. Here, the bag is formed into a bag shape and receives the bag from the bag guide chute 28 as appropriate, and when the bag detects a predetermined weight, capacity, predetermined supply time, or the like, the block corresponding to the top of the bag is blocked. The top part is sealed (welded) and the upper part of the seal part is cut by a cutter 29 (FIG. 6). The cut bag is filled with the predetermined section of bag and discharged from the discharge unit 21a of the bag pack device 21 to the outside of the bag pack device 21. When a start signal is input to the bag pack device 21, the bag is supplied from above the bag-like film F in the standby state, and when a predetermined section (the bag weight, bag capacity, or supply time) is reached, the top seal is welded → One cycle of process bottom seal welding → feeding a predetermined length → vertical polymerization portion welding → standby is executed. Even if the activation signal is turned off in the middle of the operation, the operation for one cycle can be continuously executed.

  A bag pack conveyor 23 in the form of a belt conveyor which is inclined so as to become lower toward the operation chamber 9 side on the front side along the one side wall (right side in the illustrated example) of the machine room 11 is configured, In this configuration, the bag pack P discharged from the bag pack device 21 is conveyed. The end of the transport conveyor 22 is configured to be switched to a transport state and a transport stop state when the conveyor drive motor 25 is switched on and off by looking into the basket housing portion 24 provided on the operation chamber 9 side.

  The operation panel 14 has a coin insertion slot 4 for inputting a fee, a barcode sensor (not shown) for reading a barcode instead of inserting a coin, a return lever 31 for returning a fee, and a fee display for displaying an insertion fee. A part 32, a pilot lamp 33 for displaying an abnormality, and the like are arranged. Further, below the coin insertion slot 4, as a milling degree selection switch 5 for selecting a milling work course, an upper white switch 5C, a standard switch 5D, an eight-minute switch 5E, and a no-wash rice switch 5F are provided. Provide.

  On the surface of the operation panel 14 or in the vicinity of the white rice hopper 13, a paddle pack take-out switch 35 is disposed. When the soot pack take-out switch 35 is turned ON, a soot pack signal is output, and the drive motor 20 of the soot transporting device 19 outputs a forward drive output signal, an operation output signal to the soot pack device 21, and the soot pack transport. A drive output signal of the conveyor 23 is output so as to be executed at a predetermined timing.

  Here, the operation | movement of the rice bran pack apparatus 21 of an automatic rice milling apparatus is demonstrated based on a flowchart (FIG. 9). On the operation room 9 side, the user throws brown rice out of the brown rice hopper 1. Next, when a predetermined coin is inserted into the coin insertion slot 4, a coin mech signal is output and an activation signal is output to each part (step 101). Specifically, when the degree of milling is set after the coin is inserted, each part of the apparatus starts operation sequentially, and the activated brown rice is predeterminedly polished by the activation of each part. Next, it is input whether the soot pack take-out switch 35 is ON or OFF, and if it is determined that the soot pack activation signal is output when the switch 35 is ON (step 102), the built-in timer is activated to operate for a predetermined time Tn. When the time has elapsed (steps 103 and 104), each part of the rice milling equipment is driven (step 105), and the paddle pack device 21 is also activated. Here, the waiting for the elapse of the predetermined time Tn is based on the assumption that the bag pack device 21 is in a state where it is difficult to immediately receive the bag by stopping during the previous cycle in the previous operation.

As the rice milling operation progresses, the koji transport spiral 19b is also linked to forward rotation so that koji is supplied and guided one after another to the bag-shaped film waiting on the koji pack device 21 (steps 106 and 107). When the amount of soot generated reaches a predetermined amount (step 108), the bag forming operation of the soot pack device 21 is performed. Here, whether or not the generation amount of rice bran has reached a predetermined amount is determined based on whether the rotational speed of the rotary valve 1a provided in the brown rice hopper 1 part and feeding the brown rice toward the first cerealing device 16 has reached the predetermined rotational speed. In this case, various cases are conceivable, such as when the forward rotation interlocking time of the transfer helix 19b sent to the bag pack device 21 by the bag transfer device 19 reaches a predetermined value, or when a separately configured weight sensor detects a predetermined weight.
When the amount of soot generated reaches a predetermined amount in step 108, the timer means operates to interlock the reverse of the soot transport spiral 19b for a predetermined time Tm (steps 109 to 112). Within this period, the bag pack device 21 performs a bag top seal (welding) and a cutter cutting action (step 110).

  When the predetermined time Tm elapses, the bag pack device 21 draws the film into the next bag standby state, forms it into a bag shape, and waits in a posture to receive the bag (step 113). Thereafter, the conveyor 23 is activated and transports the bag pack P fed out from the discharge port, and sends it to the bag storage section 24 of the operation chamber 9 (step 114). At the same time, the soot transport spiral 19b is switched to normal rotation, and the soot pack device 21 is again in the soot collecting state (step 115). In step 114, the conveyor 23 may be driven for the time that one bag pack P is fed to the bag storage unit 24.

  If the soot pack take-out switch 35 is OFF in step 102 and the soot pack operation signal is not output, the soot transport spiral 19b is in a reverse state and the soot collection to the soot pack device 21 is not performed (step 116).

  When it is determined whether or not the rice milling process for the number of inserted coins has been completed, each unit stops operating (steps 118 and 119).

  In the rice milling equipment provided with the paddle pack takeout switch 35 as described above, the following configuration is added. In other words, the bag pack amount setting means S is provided so that the user can set the bag amount to be packed. As for the amount of rice bran, paying attention to the amount of generated rice being proportional to the amount of brown rice to be processed, as described above, the rotary valve 1a is provided in one part of the brown rice hopper and feeds the brown rice toward the first cerealing device 16. And the number of rotations of a feed roll (not shown) of the brown rice feed unit to the rice milling apparatus 10 are counted. Further, as a method for confirming the amount of the bag itself, there is a method of counting the forward rotation interlocking time of the transfer spiral 19b sent to the bag pack device 21 by the bag transfer device 19 and detecting it with a separately configured weight sensor.

  As a specific example of the kite pack amount setting means S, in the embodiment, the operation panel 14 is provided with a liquid crystal display unit 36 and can be increased or decreased in increments of 0.5 kg from 0.5 kg to 3.0 kg. Switches 37U and 37D are provided. The user presses the bag pack removal switch 35 and touches the increase / decrease switches 37U and 37D to set a desired amount of bag. If comprised in this way, the amount of dredging of a soot pack taking out can be set previously, and a desired soot amount taking out becomes possible. In this case, even when the soot pack take-out switch 35 is pressed and turned on, if there is no increase / decrease switch 37U, 37D operation, the work is performed with a preset soot amount Nkg (for example, 3 kg). In this case, if the user is warned that the setting is not set by blinking the display of the weight Nkg (for example, 3 kg), the user can notice and change the setting to the desired weight. . As described above, in order to manage the amount of soot generated, when the soot pack device 21 is in a standby state, the rotational speed of the rotary valve 1a and the forward rotation interlocking time of the transfer spiral 19b of the soot transfer device 19 ( Alternatively, the number of rotations) is stored.

  Next, the flowchart of FIG. 10 will be described. FIG. 10 shows the state of billing for brought-in brown rice. The operation time is set according to the weight of the brown rice, and the user inserts a coin corresponding to his / her own brown rice. Conventionally, the rice milling equipment is activated by the setting switch operation of the degree of whitening after the coin is inserted. In the structure shown in FIG. (Step 202), each part operates by the whitening setting (Steps 203 and 204). That is, at the start of rice milling, the insertion of the coins for the paddy pack is an essential condition for the rice milling operation. Next, after the predetermined work is completed and each part is stopped, it is determined whether or not the bag pack P has been taken out from the bag storage unit 24. The billing amount corresponding to the coin for use is returned (steps 210 and 211). If comprised in this way, the collection | recovery by the user of the rice bran pack P will be urged, and the automatic rice milling equipment installation side will omit the trouble of collecting the rice bran pack P. Can be prevented.

  In addition, as a specific means for detecting the removal of the soot pack in the above step 210, the soot pack P depositing state detecting means (camera detecting means) deposited on the soot collecting unit 24 is provided, and this deposition state is monitored. Thus, there is a means for determining whether or not the bag pack P is taken out. Moreover, the structure which determines with a user's intention of taking back the bag pack P by the presence or absence of switch operation of the bag pack extraction switch 35 may be sufficient.

  FIG. 11 is provided with film remaining amount detecting means Q (pack bag remaining amount detecting means) for detecting that the film for forming the pack bag of the bag pack device 21 is remaining, and this detecting means Q is less than a predetermined amount. Is detected, an alarm is displayed, and the guidance is switched to the take-out port 38 provided on the operation chamber 9 side with the soot discharged (steps 304 to 308). As a specific example of the film remaining amount detection means Q, a mark on the surface of the roll core is read by an optical sensor. When the thickness of the transparent film is reduced by feeding, the mark appears so that an image can be taken. When this is detected, there is a configuration in which it can be determined that the remaining amount is small. The form which can detect the thickness of a film directly may be sufficient.

  If comprised in this way, the situation where the bag pack apparatus 21 will operate | move continuously without a bag being shape | molded can be avoided, and a user can still be provided with a bag.

  The examples shown in FIGS. 12 to 14 relate to an improvement of the soot transfer device 19 under the cyclone 18. A bag transfer device 19A having a guide opening 40 to the bag pack device 21 and a guide opening 41 to the bag bag 22 includes a transfer spiral 19b extending between the guide openings 40, 41. The separated soot from the cyclone 18 located on the side close to the kite pack device 21 is transferred to the kite pack device 21 side by forward rotation of the transfer spiral 19b, and transferred to the kite bag 22 side having a slightly longer distance by reverse rotation. It is the structure to do. When the operation of the soot pack device 21 is switched, the transfer spiral 19b of the soot transfer device 19A may be stopped. At this time, if the discharge port of the cyclone 18 communicates directly with the guide opening 40, soot is ejected from the cyclone 18 It will be in the state which will receive an effect | action and will scatter from the guide opening part 40. FIG. However, such a scattering state can be avoided by arranging the guide opening 40 to the kite pack device 21 at a distance X from the transfer kite 19a directly below the cyclone 18 as described above.

  Next, the example shown in FIG. 13 is provided with a feeding valve 42 for supplying soot, and can be driven in a fixed amount by appropriately rotating it with a drive motor. By stopping the rotation of the feeding valve 42, it can be replaced with a shutter. In FIG. 13A, the feeding state is obtained by rotating the feeding valve 42 in the forward direction, and when stopped, the shutter can be replaced as described above. The configuration shown in FIG. 13B is a configuration in which the feeding valve 42A is switched and linked to forward / reverse, so that it can be supplied to the bag pack device 21 in forward rotation and can be accommodated in the bag 22 in reverse rotation. In this way, a single discharge port can be configured and a shutter function is provided by stopping the feeding valve 42A, thereby reducing the number of parts.

  In the example in FIG. 14, the transfer rod 19b and the transfer spiral 19a of the rod transfer device 19B are arranged in an inclined state. If comprised in this way, the succeeding soot in a soot pack will not be discharged | emitted from the discharge opening part 40 to the soot pack apparatus 21 without darkness.
