Description

The present invention relates to rice milling equipment that mills rice by paying a fee.

A rice milling facility is known that has a guest room door at the front of the building for users to enter and exit the guest room, which can be opened and closed manually by the user (Patent Document 1).

In addition, a rice milling facility is known in which the guest room entrance is an automatic door and an entrance fee insertion section 1f using a coin slot, card reader, or the like is provided near the guest room entrance to open the door. This means that the guest room entrance door will not open unless the entrance fee is paid at the entrance fee insertion section, thus cutting out unnecessary visitors and preventing vandalism and theft (Patent Document 2).

JP 2017-113708 A JP 2009-50832 A

In particular, in the case of an automatic door that can be opened and closed automatically when an entrance fee is paid, as in Patent Document 2, third parties cannot enter, which has the effect of preventing vandalism and theft.

However, when users use the rice milling equipment, they head to the building carrying a bag of brown rice containing 10 kg or more of brown rice in both hands, and when they enter their guest room, they must first put the bag on the ground to open the entrance door, then pick up the bag again to enter the guest room, which is a burden and bothersome as it involves lifting and lowering heavy luggage.

The objective of the present invention is to make it easier for passengers to enter and exit a passenger room while holding a bag of brown rice or the like in both hands.

In order to solve this problem, the invention described in claim 1 is a rice milling facility in which a building 1 is divided into a machine room 3 and a passenger room 4 by a partition wall 2, and an entrance door 20 that opens and closes automatically is provided at the entrance to the passenger room 4, and entrance door opening and closing detection sensors 24, 26 are provided at the bottom of the building 1, and the entrance door opening and closing detection sensors 24, 26 are configured to output an entrance door open signal when they detect the approach of an object.

The invention described in claim 2 is the invention described in claim 1, in which the entrance door 20 is configured to slide left and right to open and close the entrance section, and the entrance opening and closing detection sensor 24 is provided on the outside of the support pillar 27 of the building 1 adjacent to the starting end side of the opening operation of the entrance door 20.

The invention described in claim 3 is the invention described in claim 1, in which the entrance door 20 is configured to slide left and right to open and close the entrance, and the exit opening and closing detection sensor 26 is provided on the passenger compartment 4 side of the building 1 support 27 adjacent to the starting end of the opening operation of the entrance door 20.

The invention described in claim 4 is the invention described in claim 2 or claim 3, in which a brown rice input hopper 5 is provided on one of the left and right sides of the partition wall 2, and a white rice tank 11 for storing white rice is provided on the other side, and an inlet opening/closing detection sensor 24 is provided on a support 27 facing the input hopper 5, and an outlet opening/closing detection sensor 26 is provided on a support 27 facing the white rice tank 11.

The invention described in claim 5 is the invention described in claim 2 or claim 3, in which a left entrance door 20L and a right entrance door 20R are provided in a two-leaf sliding door configuration, and multiple entrance opening/closing detection sensors 24L, 24R and exit opening/closing detection sensors 26L, 26R are arranged to correspond to the left and right entrance doors 20L, 20R, respectively.

According to the invention described in claims 1 and 2, the entrance/exit opening/closing detection sensors 24, 26 are provided at a low position on the bottom of the building 1 outside the passenger compartment 4. Therefore, even if a user is holding a bag of brown rice or polished rice with both hands, the entrance/exit opening/closing detection sensors 24, 26 detect this by bringing the user's feet close to the bag and output an entrance/exit door open signal, allowing the entrance/exit door 20 to open and allowing the user to easily enter and exit through the open entrance/exit.

According to the invention described in claim 2 or claim 3, in the invention described in claim 1, the entrance door 20 opens as soon as the user's foot is detected, making it easy for the user to enter and exit.

In addition to the effects of claims 2 and 3, the invention described in claim 4 makes it easy to enter the passenger compartment 4 because the input hopper 5 is right in front of the passenger when the entrance door 20 opens. On the other hand, by providing the exit opening/closing detection sensor 26 on the support 27 facing the white rice tank 11, a user who has bagged polished rice in the white rice tank 11 can quickly approach the exit opening/closing detection sensor 26 even while holding the bag, making it easy to exit the passenger compartment 4.

The invention described in claim 5 has the same effect as claims 2 and 3, and also allows easy entry and exit from either the left or right entrance of building 1.

The following describes a fee-based rice milling system according to an embodiment of the present invention.

As shown in Figures 1 and 2, the rice milling facility is constructed with a building 1 separated in the front-to-rear direction by a partition wall 2 into a machine room 3 and a passenger room 4.

As shown in Figures 2, 3, and 4, the rice milling equipment is equipped with an input hopper 5 that stores brown rice brought by users, a rotary valve 6 that discharges the brown rice from the input hopper 5, a first elevator 7 that receives the discharged brown rice and lifts it up, a stone remover 8 that separates and sorts out stones mixed in with the brown rice, a second elevator 9 that lifts the brown rice sorted by the stone remover 8, a rice milling machine 10 that mills the brown rice to make white rice, and a white rice tank 11 that stores the white rice.

The input hopper 5 and the white rice tank 11 are arranged facing the passenger compartment 4, while the first elevator 7, stone remover 8, second elevator 9 and rice polisher 10 are arranged on the machine room 3 side. The input hopper 5 is arranged on one side of the passenger compartment 4, left or right, while the white rice tank 11 is arranged on the other side of the passenger compartment 4. Between the input hopper 5 and the white rice tank 11 is a control panel 15 on whose surface a whiteness selection switch 12 for setting the whiteness, a fee slot 13 for inserting the fee, a change return slot 14 and the like are arranged. On the front side of the input hopper 5 is an opening/closing shutter 16 for opening and closing the input slot of the input hopper 5.

As shown in Figures 5(A), (B), 6 and 7, left and right sliding entrance doors 20 are provided at the entrances of the building 1 and the guest rooms 4. The two entrance doors 20 are in the form of so-called sliding doors, and the left and right doors 20L, 20R are provided so that they can be automatically operated independently from a fully open state to a fully closed state by electric motors 21L, 21R, fully open detection limit sensors 22L, 22R, and fully closed detection limit sensors 23L, 23R. The open command signal or close command signal of the electric motors 21L, 21R is transmitted as follows to control the opening and closing of the left and right entrance doors 20L, 20R.

As a premise, entrance opening/closing detection sensors 24L, 24R are provided at a low position on the outside of the passenger compartment of the entrance/exit doors 20L, 20R. The entrance opening/closing detection sensors 24L, 24R are in the form of capacitance-type proximity sensors, and are configured to switch ON when they detect, for example, the approach of a user's feet. In addition, a human detection sensor 25 is provided at an appropriate location in the passenger compartment 4, for example, on the front side of the control panel 15. The human detection sensor 25 is of an ultrasonic or infrared type, etc., and is configured to radiate light in a wide range, up, down, left and right, as shown in Figure 6, so that it can detect the presence or absence of a user in the passenger compartment 4.

The opening and closing control of the entrance door 20 will be described with reference to the flowchart in Figure 8. When a user approaches the left entrance door 20L and places their feet close to the entrance opening and closing detection sensor 24L to turn it on (S101), an open command signal is output (S102), the electric motor 21L rotates forward, and the entrance door 20L opens (S103). When the user enters the passenger compartment 4 through the open entrance door 20L side entrance, the human detection sensor 25 turns on and detects the presence of a person in the passenger compartment 4. In this state, when the user inserts the usage fee into the fee slot 13, a close command signal is output, the electric motor 21L rotates in the reverse direction, and the entrance door 20L closes (S104 to S107).

Next, when the degree of polishing is set by operating the degree of polishing setting switch 12, a polishing operation start signal is output, and the drive motors of the elevators 7, 9, stone remover 8 and rice polisher 10 are driven to start the rice polishing operation (S108-S110). During this polishing operation, the entrance opening/closing detection sensors 24L, 24R are restricted to be ON (S111). In other words, during this time, the left and right entrance doors 20 cannot be opened together. Therefore, even if someone approaches the entrance opening/closing detection sensors 24L or 24R and tries to turn the sensors ON, this is restricted, preventing unauthorized entry and exit.

Next, regarding the control related to the exit opening/closing detection sensors 26L, 26R provided inside the passenger compartment 4, when the exit opening/closing detection sensor 26L detects the approach of the feet of a user in the passenger compartment 4, an open command signal is output to the left entrance/exit door 20L, the electric motor 21L is driven in the forward direction, and the entrance/exit door 20L is opened. Similarly, the exit opening/closing detection sensor 26R opens the entrance/exit door 20R. Therefore, when the rice polishing operation is completed and the exit opening/closing detection sensor detects the approach of the feet of a user on the right side 26R, for example, an open command signal is output to the right entrance/exit door 20R, the electric motor 21R is driven in the forward direction, and the right entrance/exit door 20R closer to the white rice tank 11 is opened (S112 to S115). Then, when the entrance door open signal is output, the ON restriction on the entrance opening/closing detection sensors 24L and 24R is released (S116), and the entrance door is reset so that it will not be affected when the next user opens or closes it.

When the rice milling operation is in progress in S112 and the user attempts to leave the guest room 4, the exit opening/closing detection sensor, for example the left side 26L, detects the user's feet approaching (S117), and an open command signal is output to the left entrance/exit door 20L, the electric motor 21L rotates forward, and the left entrance/exit door 20L closest to the input hopper 5 opens (S118, S119). Note that after a predetermined time (for example, 30 seconds) in S119, a close signal is output and the entrance/exit door 20L closes, but the entrance/exit door open output in S118 releases the ON restriction of the entrance/exit opening/closing detection sensors 24L, 24R (S120). Therefore, even if the user is outside the guest room 4 and the entrance/exit door 20L is closed, the entrance/exit door 20L can be opened by turning on the entrance/exit opening/closing detection sensor 24L (S121 to S123). After a predetermined time has elapsed, the entrance/exit door 20L closes (S123), after which control returns to S110.

If the human detection sensor 25 does not turn ON in S104 above and a predetermined time has elapsed, a close command signal is output, the electric motor 21L rotates in the reverse direction, and the entrance door 20L is closed (S124-S126). This is the case when it is presumed that a small animal or bird other than a user has reacted to the entrance opening/closing detection sensors 24L, 24R, and it is possible to prevent the entrance door 20 from being accidentally opened. Note that a configuration may be adopted in which an alarm sound is output in response to the entrance door close command signal in S125.

The entrance opening/closing detection sensors 24L, 24R are provided at a low position on the outside of the passenger compartment of the entrance/exit doors 20L, 20R, so that the entrance opening/closing detection sensors 24L, 24R can be turned ON by the approach of the foot, allowing the user to easily enter the passenger compartment 4 even when holding a bag containing brown rice in both hands. The exit opening/closing detection sensors 26L, 26R are also provided at a low position, so that the exit opening/closing detection sensors 26L, 26R can be turned ON by the approach of the foot, allowing the user to easily exit the passenger compartment 4 even when holding a bag containing polished rice in both hands.

The entrance opening/closing detection sensors 24L, 24R are installed on the outside of the building 1 support pillars 27L, 27R adjacent to the opening end side of the entrance/exit doors 20L, 20R. Therefore, it is easy for users to enter through the entrance/exit doors 20L, 20R, which open immediately when the entrance opening/closing detection sensors 24L, 24R detect the approach of the user's feet.

In the above embodiment, the entrance doors 20 are two sliding doors, and the entrance opening/closing detection sensors 24L, 24R and the exit opening/closing detection sensors 26L, 26R are arranged to correspond to the left and right entrance doors 20L, 20R, respectively, so that the left and right entrance doors 20L, 20R can be opened and closed from the outside or the passenger compartment 4 side as desired.

By the way, it is advisable to provide at least the entrance opening/closing detection sensor 24 on the support 27 (27L in the illustrated example) facing the brown rice input hopper 5. When the entrance/exit door 20L opens to enter the guest room 4, the input hopper 5 is right in front of the user, making it easy to enter. On the other hand, by providing the exit opening/closing detection sensor 26 on the support 27 (27R in the illustrated example) facing the white rice tank 11, a user who has bagged polished rice in the white rice tank 11 can quickly approach the exit opening/closing detection sensor 26 even while holding the bag, making it easier to leave the guest room 4.
