A control panel 15 is provided. An opening/closing shutter 16 for closing/opening the input port of the input hopper 5 is provided on the front side of the input hopper 5. - 特許庁

A left-right sliding door (door for entrance and exit) 20 is provided at the entrance/exit of the guest room 4 of the building 1 . The two entrance/exit doors 20 are in the form of so-called sliding doors, and the left and right doors 20L and 20R are independently operated by electric motors 21L and 21R, fully open detection limit sensors 22L and 22R, and fully closed detection limit sensors 23L and 23R. It is provided to be automatically operable from the fully open state to the fully closed state. An open command signal or a close command signal for the electric motors 21L and 21R is transmitted as follows to control the opening and closing of the left and right entrance/exit doors 20L and 20R.

The opening and closing operation of the left side door 20L of the entrance door 20 will be described below. As a premise, a switch (entrance opening switch) 31 is provided at a low position outside the passenger compartment of the entrance door 20L. As shown in FIG. 6, the doorway open switch 31 is arranged as switches 31a and 31b at two locations, one on the outside and one on the inside of the passenger compartment 4. It is a configuration in which each switch is switched to ON by contacting.

Either the switch 31a or the switch 31b is turned on, and it is set so as not to be turned on at the same time. Based on one of the ON signals, the controller C transmits an opening signal for the opening/closing door 20L, and outputs an opening command signal to the electric motor 21L. Even if the ON input of the switch 31a or 31b continues, the output of the open command signal to the electric motor 21L is stopped along with the detection of the full-open detection limit sensor 22L.

The switch button 32, as shown in FIGS. 1 and 5, is provided on the outside of the pillar 27L of the building 1 adjacent to the opening operation start side of the access door 20L. 5 and 6 so as to be slidable back and forth within the cylindrical boss body 33, and when one end side is pushed from the outside of the opening/closing door 20, it slides and moves away, and the other end portion is the passenger compartment 4. (Fig. 5(A), Fig. 6(A)), and conversely, when the end on the passenger compartment 4 side is pushed, it slides to retreat and the outer end protrudes (Fig. 5(B)). , FIG. 6(B)). This operation is set to a height and size that can be performed by toe operation in the embodiment.

Furthermore, the switch button 32 is biased to one side by a spring 34 wound thereon. In this embodiment, the force is applied toward the outside of the building 1 . The cylindrical boss body 33 is provided with an electromagnetic solenoid 35 which acts on the switch button 32 and maintains the switch button 32 in a protruding state toward the passenger compartment 4 (FIG. 6(B)) against the spring 34 .

Further, a human detection sensor 25 is provided at an appropriate place in the cabin 4, for example, on the front side of the control panel 15. As shown in FIG. The human detection sensor 25 is of an ultrasonic type infrared type or the like, and as shown in FIG.

Next, mainly referring to FIGS. 8 to 11, the configuration and operation of the rice milling equipment according to the embodiment of the present invention will be described more specifically.

The opening/closing control of the entrance/exit door 20 will be described based on the flowchart of FIG. When the user approaches the left entrance door 20L and presses the end operation surface of the switch button 32 with the toe to turn on the entrance opening switch 31a (S101), an open command signal is output (S102) by the electric motor. 21L is driven to rotate forward, and the entrance/exit door 20L is opened (S103). At S102, the electromagnetic solenoid 35 is turned on, and the switch button 32 is pushed and held at the operating position. Then, when the user enters the passenger compartment 4 through the door 20L that has been opened, the human detection sensor 25 is turned on to detect the presence of a person in the passenger compartment 4 (S104). In this guest room 4, the user inserts the usage fee from the fee input port 13, and then operates the polishing degree setting switch 12 to set the polishing degree (S105, S106). Then, the electric motor 21L is reversely driven and the door 20L is closed (S107, S108). At the same time, a rice-polishing operation start signal is output to drive the elevators 7 and 9, the destoner 8 and the rice-polishing machine 10, and the rice-polishing operation is started (S109, S110).

During this rice polishing operation, the electromagnetic solenoid 35 is continuously turned on to be energized, and the switch button 32 maintains a state in which the outer end enters the cylindrical boss body 33 . That is, during this time, the switch button 32 cannot be operated from the outside of the building, and the access door 20L cannot be opened. Therefore, it is impossible for others to come in and out of mischief by approaching.

During the rice polishing operation, it is determined whether or not the doorway open switch 31b is ON (S111). The doorway open switch 31b is turned on when the operator opens the opening/closing door 20 to go out of the building, and presses the switch button 32 projecting from the cabin 4 side. by action. That is, the switch button 32 slides against the excitation of the electromagnetic solenoid 35 to turn on the doorway opening switch 31b. In this case, the operation proceeds to S113, which will be described later, and the opening/closing door 20L can be opened.

When it is determined in S111 that the entrance/exit opening switch 31b is not turned ON and the rice polishing operation ends (S112), the electromagnetic solenoid 35 is demagnetized by the rice polishing operation end signal (S113), and the switch protrudes toward the inside of the cabin 4 due to the action of the spring 34. The button 32 slides toward the outside of the building to turn on the exit opening switch 31b (S114). As a result, an open command signal is output to the left access door 20L, the electric motor 21L is driven forward, and the access door 20L is opened. (S115-S116). When the electromagnetic solenoid 35 is demagnetized, the spring 34 maintains the switch button 32 in a protruded state outside the building, and is reset so as not to hinder the opening and closing of the entrance door by the next user.

When the human detection sensor 25 is not turned ON in S104 and a predetermined time has elapsed, a close command signal is output to demagnetize the electromagnetic solenoid 35, the electric motor 21L is reversely driven, and the access door 20L is closed (S117). ~S119). Even if it is estimated that a small animal or bird other than the user has touched the switch button 32, it is possible to avoid an unexpected open state of the access door 20. - 特許庁It should be noted that an alarm sound may be output in response to the entry/exit door closing command signal in S118.

According to the above embodiment, when a user enters an unmanned guest room 4 with a bag of brown rice, the operating surface of the switch button 32 protrudes outside the building 1, so that the user can operate it. When the switch button 32 is operated, the opening/closing door 20 is opened and the user enters the passenger compartment 4. At this time, the operating surface of the switch button 32 from outside the building 1 enters the cylindrical boss body 33 to retreat and switch. Since the button 32 protrudes toward the cabin 4, it cannot be operated from outside the building 1. Therefore, the user in the guest room 4 can use the rice polishing equipment without being disturbed by others.

Since the switch button 32 is provided at a low position outside the passenger compartment of the entrance doors 20L, 20R, the entrance opening switches 31a, 31b can be turned on by foot operation, and the user can hold the brown rice storage bag with both hands. Even when trying to enter the cabin 4, the passenger can easily enter the cabin 4.例文帳に追加In addition, it is possible to prevent the door 20 from opening by detecting a person passing in front of the rice milling facility.

In the above-described embodiment, the electromagnetic solenoid 35 is provided on the side of the cylindrical boss body 33 through which the switch button 32 is inserted to maintain the position of the switch button 32 biased by the spring 34 or to return to the original position by the biasing force of the spring 34 . Since the opening and closing door 20 is automatically opened at the end of the rice polishing operation, the operation of the switch button 32 from the side of the guest room 4 can be omitted. The switching operation may be performed by simply sliding the switch button 32 by toe operation.

In addition, in the above-described embodiment, after the bill is inserted, the selection operation of the milling degree selection switch 12 is configured to output the door closing command signal for entry and exit. The entry/exit door 20 is closed and safe.

It should be noted that the same effect can be obtained by adopting a configuration in which the entry/exit door closing command signal is output after the toll is inserted.

Furthermore, if the human detection sensor 25 does not detect a person for a predetermined period of time after the door 20 is opened, the door closing command signal is output to close the door 20. Since it is demagnetized, it is configured to return to the state of protruding outside the building 1 by the action of the spring 34, so that the door 20 can be avoided from being opened when there is no one in the guest room 4, and unexpected accidents and theft can be prevented. .

Next, instead of the switch button 32, a configuration for detecting the approach of the user's feet and controlling the opening/closing of the entry/exit door 20 will be described. As a premise, as shown in FIG. 10, entrance opening/closing detection sensors 24L and 24R are provided at low positions outside the passenger compartment of entrance/exit doors 20L and 20R. The entrance opening/closing detection sensors 24L and 24R are in the form of capacitance type proximity sensors.

In the flow chart of FIG. 11, when the user approaches the left entrance door 20L and turns on the entrance opening/closing detection sensor 24L (S201), an open command signal is output (S202) and the electric motor 21L rotates forward. The door 20L is driven to open (S203). When the user enters the guest room 4 through the door 20L side door that has been opened, the human detection sensor 25 is turned ON to detect the presence of a person in the guest room 4. In this state, the user inserts the charge from the charge input port 13. , the closing command signal is output, the electric motor 21L is reversely driven, and the access door 20L is closed (S204 to S207).

Next, when the polishing degree setting switch 12 is operated to set the polishing degree, a rice polishing operation start signal is output, and the driving motors of the elevators 7 and 9, the destoner 8 and the rice polishing machine 10 are driven to start the rice polishing operation (S208). ~S210). During this rice polishing operation, the entrance opening/closing detection sensors 24L and 24R are set to the ON restriction state (S211). That is, during this period, the access door 20 cannot be opened on both the left and right sides. Therefore, even if another person approaches the entrance opening/closing detection sensor 24L or 24R and tries to turn on the sensor, this is regulated, and it is impossible to enter or leave the entrance for mischief.

Next, regarding the control related to the exit opening/closing detection sensors 26L and 26R provided inside the cabin 4, when the exit opening/closing detection sensor 26L detects the approach of the user's feet in the cabin 4, the left entrance/exit door 20L is opened. A command signal is output, the electric motor 21L is driven to rotate forward, and the entrance door 20L is opened. Similarly, the exit opening/closing detection sensor 26R opens the entry/exit door 20R. Therefore, when the rice milling operation ends and the exit opening/closing detection sensor, for example, the right exit opening/closing detection sensor 26R detects the approach of the user's feet, an open command signal is output to the right entrance/exit door 20R, and the electric motor 21R rotates forward. The right door 20R close to the polished rice tank 11 is opened (S212-S215). Then, when the entrance door open signal is output, the ON regulation of the entrance opening/closing detection sensors 24L and 24R is released (S216), and a reset state is set so as not to hinder the opening/closing of the entrance door by the next user.

When the user tries to go out of the passenger compartment 4 during the rice polishing operation in S212, the exit opening/closing detection sensor, for example, the left exit opening/closing detection sensor 26L is caused to detect the approach of the user's feet. Then (S217), an open command signal is output to the left entrance/exit door 20L, the electric motor 21L is driven forward, and the left entrance/exit door 20L near the input hopper 5 is opened (S218, S219). In S219, after a predetermined time (for example, 30 seconds), the door 20L is closed by outputting the closing signal. (S220). Therefore, even if the user is outside the guest room 4 and the door 20L is closed, the door 20L can be opened by turning on the entrance opening/closing detection sensor 24L (S221 to S223). After the predetermined time has elapsed, the access door 20L is closed (S223), but the control returns to S210 thereafter.

When the human detection sensor 25 is not turned ON in S204 and the predetermined time has elapsed, the closing command signal is output and the electric motor 21L is reversely driven to close the access door 20L (S224-S226). Even if small animals or birds other than the user are presumed to have reacted to the entrance opening/closing detection sensors 24L and 24R, it is possible to avoid an unexpected open state of the access door 20. FIG. It should be noted that an alarm sound may be output in response to the entry/exit door closing command signal in S225.

Since the entrance opening/closing detection sensors 24L, 24R are provided at low positions outside the passenger compartment of the entry/exit doors 20L, 20R, the entrance opening/closing detection sensors 24L, 24R can be turned ON by the approach of the user's foot, and the user can eat brown rice. Even when trying to enter the passenger compartment 4 while holding the storage bag with both hands, the user can easily enter the passenger compartment 4.例文帳に追加Since the outlet opening/closing detection sensors 26L and 26R are similarly provided at a low position, the exit opening/closing detection sensors 26L and 26R can be turned ON by the approach of the user's foot, and the user can hold the milled rice storage bag with both hands. However, it is possible to easily exit to the outside of the guest room 4.

The entrance opening/closing detection sensors 24L and 24R are provided outside the pillars 27L and 27R of the building 1 adjacent to the starting ends of the opening operation of the entrance/exit doors 20L and 20R. Therefore, the user can easily enter through the entry/exit doors 20L, 20R which open immediately upon detection of foot approach by the entrance opening/closing detection sensors 24L, 24R.

The entrance/exit door 20 has a so-called double sliding door configuration, and entrance opening/closing detection sensors 24L and 24R and exit opening/closing detection sensors 26L and 26R are arranged to correspond to the left and right entrance/exit doors 20L and 20R, respectively. The doors 20L and 20R can be opened and closed from the outside or from the side of the guest room 4 arbitrarily to the left and right.

By the way, at least the inlet opening/closing detection sensor 24 is preferably provided on the support 27 (support 27L in the figure) facing the unpolished rice input hopper 5 side. When entering the guest room 4, when the entrance/exit door 20L is opened, the input hopper 5 is in front of the eyes, making it easy to enter. On the other hand, the exit opening/closing detection sensor 26 is provided on a support 27 (support 27R in the figure) facing the polished rice tank 11, so that the user who has packed the polished rice in the polished rice tank 11 is carrying the bag. The foot can be brought closer to the exit opening/closing detection sensor 26 more quickly, and the exit from the passenger compartment 4 is facilitated.
