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 frying brown rice put into the input hopper 2 by the user, a stone removing machine 4 for removing stones mixed in the brown rice, and a second for 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, and brown rice is supplied to either the stone removing machine 4 side or the brown rice return port 22 side on the loading hopper 2. 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 the 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 whitening degree selection switch 11 for selecting the degree of milling of rice to be milled, a charge input port 19 for inputting a charge, and an elevating switch 12 capable of raising and lowering the elevating device 9. The elevating switch 12 includes an ascending switch 12a and a descending switch 12b. Further, a brown rice return switch 24 is provided in the vicinity of the brown rice return port 22, and when the brown rice return switch 24 is operated, the brown rice in the input hopper 2 passes through the grain raising machine 3 and the brown rice return tube 23, and the brown rice is discharged from the brown rice return port 22. It is configured so that it can be discharged.

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.

As shown in FIG. 4, the rice milling equipment is provided with a control unit A to control the rice milling equipment.

An elevating device 9 is provided in front of the loading hopper 2. The elevating device 9 elevates and elevates the mounting table 14 on which the bag h for accommodating the brown rice brought by the user is placed, the weight scale 15 for detecting the weight of the bag h placed on the mounting table 14, and the mounting table 14. A lifting tool 16, a support 17 that supports the lower portion of the lifting tool 16, and a soft bellows-shaped protective cover 18 that covers the periphery of the lifting tool 16 are provided. The support 17 is installed on the floor FL of the guest room K. The initial position of the elevating device 9 constitutes a separation portion R so that the space between the mounting table 14 and the support 17 is not sandwiched between the mounting table 14 and the support 17 on which the user's feet or the like descend.

Further, by covering the space between the mounting table 14 and the support 17 with the protective cover 18, the user's feet and large foreign substances are prevented from entering from the separation portion R.

The support 17 is fixed to the partition wall 1 with a fixture 31. The fixture 31 can be attached / detached only from the machine room M side, and cannot be attached / detached by the user. Further, around the fixture 31, there is a space portion s that can be formed below the inclined surface 2a at the lower part of the charging hopper 2, which is a maintenance space for the manager of the rice milling equipment to attach / detach the fixture 31.

Next, the rice milling operation will be described with reference to FIG. 7. First, a case where about 30 kg of brown rice, which is the most common scene, is brought in and 300 yen is put into the rice polishing process will be described.

The user enters the guest room K with a bag h (for example, 30 kg) containing the brown rice brought in. When the charge detection sensor 20 detects that the charge (for example, 300 yen) has been charged into the charge input port 19, the opening / closing door 6 opens, and brown rice can be charged into the input port of the input hopper 2. When the user places the bag h on the mounting table 14 in the initial position, that is, in the lowered position after the charge is charged, the weight is detected by the weight scale 15 and 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) (S100), the lifting tool 16 is automatically driven, and the mounting table 14 is used as the loading surface of the loading hopper 2. It rises to about the same height. Alternatively, the elevating switch 12 can be operated after the charge is charged, and the elevating tool 16 is driven by the manual operation of the ascending switch 12a of the user to raise the mounting table 14. The user throws the brown rice in the bag h into the throwing hopper 2.

When the weight meter 15 has a weight outside the set range or no weight detection, the lifting device 9 is regulated both automatically and manually. The case without weight detection is a case where the user himself lifts the bag h from the outside of the lifting device 9 and throws it into the loading hopper 2. In such a case, it is not necessary to drive the lifting device 9. Moreover, raising the elevating device 9 is not preferable from the viewpoint of safety. Further, if 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 (S101), the rice milling operation is started. The operation will continue for the time corresponding to the input fee. When the presence / absence detection sensor 13 for brown rice detects the absence of brown rice during the rice milling operation (S103), the remaining rice in the rice milling machine 5 is milled to end the rice milling operation. The user puts the polished rice, which has been milled by the rice milling machine 5 and stored in the polished rice tank 7, in the bag h, and takes it home. The human detection sensor 10 detects that no one is present after the rice milling operation is completed (S104), and if the elevating device 9 is in the ascending position at that time, the elevating device 9 is lowered to the initial position.

It is safe because the lifting device 9 is lowered after the human detection sensor 10 detects that there is no user. Further, after the mounting base 14 of the elevating device 9 returns to the initial position, it is preferable in terms of safety to regulate the elevating operation by operating the elevating switch 12 until the next user pays the fee.

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

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

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

As a case of restricting the lowering operation, it is a case where a set weight or more (for example, 40 kg or more) is detected. In this case, the user may be sitting on the mounting table 14, which is not preferable 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 ascending switch 12a. Also in this case, when the set weight or more (for example, 40 kg or more) is detected, the increase is restricted. This is because, as described above, the user may be on the mounting table 14.

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

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

Next, the ascending / descending operation of the elevating device 9 in the case of automatically ascending / descending during the rice milling operation will be described.

According to the embodiment of FIG. 7, 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 is lowered to return to the initial position. There is timing. For example, when the rice milling operation is started by operating the whitening degree selection switch 11, the mounting table 14
May be controlled to descend to the initial position. In this case, when there is a next bag h containing unpolished brown rice, it is possible to quickly prepare to charge the bag h containing brown rice to be charged into the charging hopper 2 into the charging hopper 2.

The lifting operation of the lifting device 9 when the rice milling operation is stopped due to the charge running out (S102) after the operation time corresponding to the charge according to the embodiment of FIG. 7 has elapsed will be 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 injecting an additional charge (S105). 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 (S104), the opening / closing door 6 is lowered to close the operation, and then the elevating device 9 (mounting table 14) is raised. If it is in the position (S017), it descends to the initial position. Third, when the brown rice return switch 24 is operated (S106), 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 raising machine 3 and the brown rice returning cylinder 23. The user receives and stores the brown rice returned in the bag h that he brought on the input hopper 2. At this time, when the mounting table 14 is in the raised position, the bag h containing the brown rice can be placed on the mounting table 14 and lowered by maintaining the position. After accommodating the remaining brown rice from the brown rice return port 22, it is the same as after S104 in FIG.

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

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

When the mounting table 14 of the elevating device 9 is in the ascending position at the end of the rice milling operation, the elevating device 9 does not descend until the person detection sensor 10 detects no person as shown in FIG. 7 (S104, S107). The lowering switch 12b is operated to lower the mounting table 14 to the initial position. Then, the bag h can be placed on the mounting table 14, the weight of the polished rice can be measured, and the bag h can be displayed on the display screen 25.

It is possible to measure with the weigh scale 15 from the end of the rice milling operation to the detection of no person by the person detection sensor 10.

Next, a feature in the case of a simple lifting device in which the weight scale 15 is not mounted on the lifting device 9 of the present embodiment will be described.

In this case, the mounting table 14 is manually lifted and lowered by the lift switch 12.

The elevating operation by the elevating switch 12 is possible from after the charge is charged before the rice milling operation until the person detection sensor 10 detects no person after the rice milling operation is completed.

This embodiment can be used not only for rice milling equipment for milling brown rice, but also for charge-type preparation equipment such as paddy rice milling equipment for paddy rice milling and milling equipment for milling brown rice and white rice.
