[0018] A fee-based rice milling equipment according to an embodiment of the present invention will be described below.

[0019] As shown in Figures 1 and 2, the rice milling facility is configured with a building 1 divided in the front-to-back direction by a partition wall 2 into a machine room 3 and a passenger room 4.

[0020] 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 in the input hopper 5, a first elevator 7 that receives the discharged brown rice and lifts it up, a stone remover 8 that sorts and separates 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.

[0021] The feeding hopper 5 and white rice tank 11 are installed facing the passenger compartment 4, while the first elevator 7, stone remover 8, second elevator 9 and rice polisher 10 are installed on the machine room 3 side. The feeding hopper 5 is installed on one side (left or right) of the passenger compartment 4, and the white rice tank 11 is installed on the other side (right or left) of the passenger compartment 4. Between the feeding hopper 5 and the white rice tank 11 is provided a control panel 15 on whose surface there are disposed a whitening degree selection switch 12 for setting the whitening degree, a fee slot 13 for inserting the fee, a change return slot 14 and the like. On the front side of the feeding hopper 5 is provided an opening / closing shutter 16 for closing and opening the feeding opening of the feeding hopper 5.

[0022] 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 of the so-called double sliding door type, and the left and right doors 20L, 20R are provided so as to be independently operable automatically 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. An open command signal or a close command signal for the electric motors 21L, 21R is sent as follows to control the opening and closing of the left and right entrance doors 20L, 20R.

[0023] As a premise, entrance opening / closing detection sensors 24L, 24R are provided at low positions 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, for example, the approach of a user's feet is detected. 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 or the like, 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.

[0024] The opening and closing control of the entrance door 20 will be described with reference to the flow chart of Fig. 8. When a user approaches the left entrance door 20L and places his / her 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 is driven in the forward direction, and the entrance door 20L is opened (S103). When the user enters the passenger compartment 4 from the open entrance door 20L side entrance, the human detection sensor 25 is turned ON to detect the presence of a person in the passenger compartment 4, and when the user inserts the usage fee into the fee insertion slot 13 in this state, a close command signal is output, the electric motor 21L is driven in the reverse direction, and the entrance door 20L is closed (S104 to S107).

[0025] Next, when the degree of polishing is set by operating the degree of polishing setting switch 12, a rice polishing operation start signal is output, and the drive motors of the elevators 7, 9, the stone remover 8, and the rice polisher 10 are driven to start the rice polishing operation (S108-S110). During this rice polishing operation, the entrance opening / closing detection sensors 24L, 24R are restricted to ON (S111). In other words, during this time, the entrance / exit door 20 is configured so that both the left and right doors cannot be opened. Therefore, even if someone approaches the entrance opening / closing detection sensor 24L or 24R and tries to turn the sensor ON, this is restricted, preventing unauthorized entry and exit.

[0026] 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 normal 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 to, for example, the right side 26R, an open command signal is output to the right entrance / exit door 20R, the electric motor 21R is driven in the normal direction, and the right entrance / exit door 20R close to the polished rice tank 11 is opened (S112 to S115). When the entrance door open signal is output, the ON restriction of the entrance opening / closing detection sensors 24L, 24R is released (S116), and a reset state is entered so that the entrance door can be opened and closed by the next user without any problems.

[0027] When the rice milling operation is in progress in S112, if the user attempts to go outside 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 close 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 entrance / exit door 20L is closed when the user is outside the guest room 4, 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 door 20L closes (S123), and thereafter the control returns to S110.

[0028] If the human detection sensor 25 does not turn ON in S104 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 opened unexpectedly. 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.

[0029] Since 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, the entrance opening / closing detection sensors 24L, 24R can be turned on by the approach of the foot, and the user can easily enter the passenger compartment 4 even when holding a bag containing brown rice in both hands. Similarly, since the exit opening / closing detection sensors 26L, 26R are provided at a low position, the exit opening / closing detection sensors 26L, 26R can be turned on by the approach of the foot, and the user can easily exit the passenger compartment 4 even when holding a bag containing polished rice in both hands.

[0030] The entrance opening / closing detection sensors 24L, 24R are provided on the outside of the building 1 support pillars 27L, 27R adjacent to the opening operation start side of the entrance doors 20L, 20R. Therefore, a user can easily enter through the entrance doors 20L, 20R, which open immediately when the entrance opening / closing detection sensors 24L, 24R detect the approach of the user's feet.

[0031] In the above embodiment, the entrance / exit doors 20 are in the form of two so-called 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 / exit doors 20L, 20R, respectively, so that the entrance / exit doors 20L, 20R can be opened and closed from the outside or the passenger compartment 4 side as desired.

[0032] Incidentally, it is advisable to provide at least the entrance opening / closing detection sensor 24 on the support pillar 27 (27L in the illustrated example) facing the brown rice feeding hopper 5. When the entrance / exit door 20L opens to enter the guest room 4, the feeding hopper 5 is right in front of the door, making it easy to enter. On the other hand, by providing the exit opening / closing detection sensor 26 on the support pillar 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 easy to leave the guest room 4.
