In the embodiment described below, an elevator-type tower-type mechanical parking device will be described as an example of the mechanical parking device of the present disclosure, but is not limited to this example. The mechanical parking device of the present disclosure may be a vertical circulation type, a flat reciprocating type, a horizontal circulation type, a two-tier type, etc. Also, it may be a conveyor-type or fork-type mechanical parking device that does not use pallets.

[0021] FIG. 1 is a vertical cross-sectional view of a mechanical parking device 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the mechanical parking device 1 is an elevator-type tower-type multi-story parking facility capable of accommodating a plurality of vehicles 2, and includes a parking tower 5 provided with an entrance / exit gate 3 and an entrance / exit door 4. The ground floor of the parking tower 5 is a boarding / deboarding room 7 for entering and exiting the vehicle 2, and a turntable 8 for changing the direction of the vehicle 2 is installed on the floor of the boarding / deboarding room 7. The turntable 8 is configured such that a rotating plate 10 and a turning drive unit 11 are provided in a concave pit 9 formed on the floor of the boarding / deboarding room 7. Note that, in this embodiment, a case in which both entry and exit are performed in the boarding / deboarding room 7 is shown, but is not limited to this. For example, the boarding / deboarding rooms may be different for entry and exit, and a boarding / deboarding room dedicated to entry and a boarding / deboarding room dedicated to exit may be provided. Also, in this embodiment, one boarding / deboarding room is shown, but multiple boarding / deboarding rooms may be provided.

[0022] A vertical ascent passage 13 is formed in the center of the parking tower 5, within which a lift 14 (elevator-like conveyor) is provided so as to be able to ascend and descend. The lift 14 is suspended at its four corners by a number of wire ropes extending downward from a winch (not shown) provided at the top of the parking tower 5, for example, and can ascend and descend within the ascent passage 13 when the winch is activated.

[0023] Meanwhile, vehicle storage shelves 17 (parking spaces) are provided on both sides of the elevator passage 13. These vehicle storage shelves 17 are provided in multiple levels, one above the other, on either side of the elevator passage 13, and each vehicle storage shelf 17 stores one pallet 18 for loading vehicles. Note that the pillars and other elements of the vehicle storage shelves 17 are omitted from the illustration.

[0024] A transfer mechanism (not shown) is provided on the floor surfaces of the lift 14 and the vehicle storage shelf 17, which enables smooth transfer of an empty pallet 18 or a pallet 18 loaded with a vehicle 2 from the lift 14 to the vehicle storage shelf 17, or from the vehicle storage shelf 17 to the lift 14, when the heights of the two floor surfaces are the same.

[0025] 2 is a schematic perspective view showing the boarding / disembarking room 7. Inside the boarding / disembarking room 7, there is a space in the center where the pallet 18 is placed, and on the wall in front of the entrance / exit door 4, there is a mirror 24 that allows the driver (user) to check the position of the vehicle 2, and an electric parking position indicator light 25 that provides guidance on "going forward," "stopping," and "backing up."

[0026] Four cameras 35A to 35D that capture images of the interior of the boarding / deboarding compartment 7 are installed in the boarding / deboarding compartment 7. In this embodiment, the cameras 35A to 35D are, for example, video cameras, and are attached to different wall surfaces (four surfaces) of the boarding / deboarding compartment 7. Note that the number of cameras installed is not limited to the above, and it is sufficient that at least one camera is installed.

[0027] An internal detection sensor (internal detection means) 30 (see FIG. 5) for detecting a person (object) in the boarding / alighting compartment 7 is provided inside the boarding / alighting compartment. The internal detection sensor 30 may include sensors for detecting a person (object) in each of the front, right, left, and rear areas of the boarding / alighting compartment 7. As these sensors, known sensors can be appropriately adopted. Examples include a human sensor and a photoelectric sensor. The internal detection sensor 30 may also include a vehicle position detection sensor for detecting the stopping position of the vehicle. The internal detection sensor 30 may also include two range sensors 30A and 30B provided at diagonal positions of the boarding / alighting compartment 7.

[0028] 3 is a diagram showing an example of the installation positions and detection ranges of the range sensors 30A and 30B in the boarding / deboarding compartment 7. The range sensors 30A and 30B can detect people in the boarding / deboarding compartment, the presence or absence of a vehicle, etc., by emitting a search wave W, such as a laser beam or ultrasonic wave, which has the property of hitting a target and being reflected, and scanning a predetermined angle range in the horizontal direction while receiving the reflected wave.

[0029] Moreover, the above-mentioned cameras 35A to 35D can also be used as a substitute for the interior detection sensor 30. In this case, it is possible to confirm whether or not there is anyone in the boarding / deboarding compartment based on image data acquired by the cameras 35A to 35D. The interior detection sensor 30 is a sensor used to check for unoccupied inside the boarding / deboarding compartment, and is not limited to the above-mentioned various sensors. The above-mentioned various sensors may be used in combination, or other known sensors may be appropriately adopted.

[0030] As shown in FIG. 2, an entrance / exit detection sensor 32 for detecting the entrance or exit of a person or vehicle from the boarding / deboarding room 7 may be provided at the entrance / exit gate 3 of the boarding / deboarding room 7. In addition, a notification unit (notification means: not shown) may be provided in the boarding / de-boarding compartment to notify the user of information by voice (guidance information for entering and leaving the parking lot, information on the occurrence of an error, etc.) Examples of the notification unit include a speaker and a warning light.

[0031] Outside the boarding / deboarding room 7, an entrance control light 21 having blue and red lamps is provided above the entrance / deboarding door 4. Also, outside the boarding / deboarding room 7, an operation panel 22 that receives input information for closing the entrance / deboarding door 4 is provided. The operation panel 22 is operated by, for example, a user, a manager, a maintenance worker, etc. Also, a monitor 28 is provided near the operation panel 22 for displaying real-time images captured by the cameras 35A to 35D. In addition, the boarding / disembarking room 7 is provided with an emergency door 6 for workers and the like to enter and exit in emergencies or during maintenance.

[0032] In addition, a control device 40 that performs overall control of the mechanical parking device 1 is installed inside or outside the boarding / disembarking room 7. In addition, the mechanical parking device 1 is equipped with a door current control device 80 (see FIG. 6) and a conveyor current control device 90, which will be described later.

[0033] Fig. 4 is a diagram showing an example of the configuration of the operation panel 22. As shown in Fig. 4, the operation panel 22 is housed in a metal housing 43 to protect it from wind and rain and to prevent tampering, and this housing 43 is provided with a lockable lid 44. When an operator operates the operation panel 22, the operator unlocks the housing 43, opens the lid 44, and accesses the operation panel 22.

[0034] The operation panel 22 includes, for example, an authentication information input unit for receiving authentication information of a user. In the present embodiment, an IC card reader 46 is provided as an example of the authentication information input unit, but is not limited to this example. The authentication information input unit may be configured with, for example, a biometric information reading unit that reads so-called biometric authentication information such as a numeric keypad, fingerprint, iris, vein information, face image, etc., a wireless communication unit that receives authentication information via wireless communication (for example, 3G, 4G, 5G, 6G, wireless LAN, Wifi, LTE, etc.), etc.

[0035] The operation panel 22 may also be equipped with a touch panel 45, a speaker 47 for providing audio guidance to an operator (e.g., a user) on how to operate the device, an emergency stop button 48 for emergency stopping the operation of the mechanical parking device 1, a microphone, etc.

[0036] The touch panel 45 has both a display function and an input function. For example, various kinds of guidance information for performing operations for entering and leaving the warehouse are displayed on the touch panel 45, as well as operation buttons and the like for allowing the operator to perform operations for entering and leaving the warehouse. The display on the touch panel 45 is controlled by the control device 40, which will be described later, and information input by operating the touch panel 45 by the operator or the like is output to the control device 40.

[0037] FIG. 5 is a functional block diagram showing an example of functions of the control device 40 of the mechanical parking device 1 according to this embodiment. The control device 40 is, for example, an information processing device, and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for connecting to a network, and the like. The control device 40 also includes a comprehensive database 52 in which various data required for controlling the mechanical parking device 1 are stored. The comprehensive database 52 stores vehicle presence status, pallet shape type, vehicle storage shelf shape type, identification information of persons permitted to use the mechanical parking device 1, and contact information of users, etc. (for example, registered email addresses, etc.). The persons permitted to use the mechanical parking device 1 include users, managers, maintenance personnel, etc.

[0038] The control device 40 also includes a storage unit 41 for storing necessary data in association with the execution of the later-described entry process and exit process. For example, the storage unit 41 stores a user ID (first authentication information) that has been successfully authenticated in the first user authentication process, information on various modes, and the like.

[0039] The auxiliary storage device of the control device 40 stores control programs for controlling each mechanism of the mechanical parking device 1, and the CPU reads out the various programs stored in the auxiliary storage device into the main memory and executes them to realize the functions of each unit described below. In addition, when executing the programs, the CPU refers to and uses various data stored in the comprehensive database 52.

[0040] The control programs may be stored in advance in an auxiliary storage device such as a ROM when the control device 40 is manufactured, or may be downloaded and installed from a server or the like that distributes control programs and the like after construction. Alternatively, the programs may be installed via an external storage device. In this way, there is no particular limitation on the method of installing the various programs.

[0041] The control device 40 includes a main control unit 50. In addition to the above-mentioned general database 52, the main control unit 50 is connected to a storage door control unit 55, a conveyor control unit 56, a sensor control unit 57, a camera control unit 58, an image database 59, a vehicle measurement control unit 61, a turning control unit 62, and the like. The main control unit 50 is also connected to an operation panel 22, and is configured to enable two-way communication.

[0042] The entrance / exit door control unit 55 receives an operation command from the main control unit 50 and controls the door drive unit 63 that drives the entrance / exit door 4 to open and close, thereby opening and closing the entrance / exit door 4. The entrance / exit door control unit 55 also receives a position signal of the entrance / exit door 4 from the entrance / exit door sensor 65, and feeds back the information to the main control unit 50. The door driving unit 63 is configured to include, for example, a motor, etc. Note that the door driving unit 63 can appropriately employ various known configurations. The entrance / exit door sensor 65 includes, for example, a door full-open detection sensor 66 (see FIG. 12) that detects the full opening of the entrance / exit door 4, and a door full-close detection sensor 67 (see FIG. 6) that detects the full closure of the entrance / exit door 4. Any known sensor can be appropriately used as the entrance / exit door sensor 65. One example of the door full-open detection sensor 66 and the door full-close detection sensor 67 is a limit switch.

[0043] The conveyor control unit 56 receives an operation command from the main control unit 50 and controls a lift drive unit 64 that drives the lift 14, thereby controlling the raising and lowering of the lift 14 and the loading and unloading of the pallets 18. The conveyor control unit 56 also receives a position signal of the lift 14 from a conveyor position sensor 68 and feeds back the information to the main control unit 50.

[0044] The sensor control unit 57 receives a detection signal from the interior detection sensor 30 and outputs the information to the main control unit 50. The sensor control unit 57 also determines whether a person or vehicle has entered or exited based on the detection signal from the entry / exit detection sensor 32 and outputs the determination result to the main control unit 50. The sensor control unit 57 also receives a detection signal from the floor-landing detection sensor 34 and outputs the information to the main control unit 50. Here, the floor-landing detection sensor 34 is, for example, a sensor that detects that the lift 14 has landed on the boarding / deboarding compartment 7. The floor-landing detection sensor 34 is a sensor that is generally provided in mechanical parking devices (for example, the cage floor-landing detector of JP 2006-307495 A), and any known sensor may be used.

[0045] The camera control unit 58 receives an operation command from the main control unit 50, causes the cameras 35 (35A to 35D) installed inside the boarding / deboarding compartment 7 to capture images, and outputs the image information to the main control unit 50. This image information is stored in the image database 59 for a predetermined period of time. The image database 59 may be provided inside the general database 52, or on the cloud.

[0046] The vehicle measurement control section 61 receives an operation command from the main control section 50, measures the weight of the vehicle mounted on the lift 14 using the vehicle measuring device 69, and feeds back the information to the main control section 50 via the vehicle weight sensor 73. This vehicle weight information is used for controlling the lift 14, etc.

[0047] The turning control unit 62 receives an operation command from the main control unit 50 and controls the turning drive unit 11 that turns the turntable 8, thereby operating the turntable 8. The turning control unit 62 also receives a turning position signal of the turntable 8 from the turntable position sensor 71, and feeds back the information to the main control unit 50.

[0048] The main control unit 50 operates the mechanical parking device 1 based on feedback from each control unit 55, 56, 57, 58, 61, 62 and input information from the operation panel 22. The main control unit 50 also executes a control program for the entry process and a control program for the exit process based on various information exchanged with the operation panel 22. Note that the detection signals of the interior detection sensor 30, the entry / exit detection sensor 32, and the landing detection sensor 34 may be input directly to the main control unit 50 instead of being input to the main control unit 50 via the above-mentioned sensor control unit 57. This makes it possible to implement more rapid control in response to the detection signals.

[0049] FIG. 6 is a diagram showing an example of the configuration of the door current control device 80 and the transport current control device 90 according to this embodiment. 6, the door current control device 80 includes a switch (door switch) 81 and a switch control unit (door switch control means) 82. The transport current control device 90 includes a switch 91 and a switch control unit (switch control means) 92.

[0050] A power source 70 supplies power to the door drive unit 63 that drives the entrance / exit door 4. A breaker 74 is provided in the electrical circuit that connects the power source 70 and the door drive unit 63. Similarly, a power source 70 supplies power to a transportation equipment driving unit 60 that drives transportation equipment related to vehicle transportation. The transportation equipment includes a lift 14. The transportation device may also include a turntable 8. The transportation equipment driving unit 60 also includes a lift driving unit 64 that drives the lift 14. The transportation equipment driving unit 60 also may include a swivel driving unit 11 that drives the turntable 8. A breaker 75 is provided in the electrical circuit connecting the power source 70 and the transport device driving unit 60 .

[0051] In the event of an abnormality such as an overcurrent, the breakers 74, 75 are activated to cut off the power supply to the door drive unit 63 and the transport equipment drive unit 60. After an operator or the like has confirmed safety, the breakers 74, 75 are restored by the operator and the power is turned on again.

[0052] A switch 81 is provided on an electric circuit connecting the power source 70 and the door drive unit 63, downstream of the breaker 74, in other words, closer to the door drive unit 63. The switch 81 controls the power supply to the door drive unit 63. The switch 81 is, for example, a mechanical switch that switches between turning on and off power to the door drive unit 63, and examples of the switch 81 include a magnet contactor and a magnet switch. The opening and closing of the switch 81 is controlled by a switch control unit 82.

[0053] The switch control unit 82 is, for example, an information processing device, and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for transmitting and receiving information to and from other devices, etc. The auxiliary storage device of the switch control unit 82 stores a door current control program for controlling the opening and closing of the switch 81, etc., and the CPU reads out the program stored in the auxiliary storage device into the main memory and executes it to realize various processes described later.

[0054] The door current control program may be stored in advance in an auxiliary storage device such as a ROM when the switch control unit 82 is manufactured, or may be downloaded and installed from a server or the like that distributes the program after construction. Also, the program may be installed via an external storage device. In this way, there is no particular limitation on the method of installing the various programs.

[0055] For example, when the landing detection sensor 34 detects that the lift 14 has landed at the boarding / de-boarding compartment 7 during entry or exit, the switch control unit 82 closes the switch 81 to start the power supply to the door drive unit 63. Also, for example, when the vehicle has completed entering or leaving the boarding / de-boarding compartment 7 during entry or exit, and the transport of the lift 14 has started, the switch control unit 82 opens the switch 81 to cut off the power supply to the door drive unit 63. More specifically, the switch control unit 82 closes the switch 81 when a landing detection signal (on signal) is input from the landing detection sensor 34, and opens the switch 81 when a landing release signal (off signal) is input from the landing detection sensor 34.

[0056] A switch 91 is provided on an electric circuit connecting the power source 70 and the transport equipment driving unit 60, downstream of the breaker 75, in other words, closer to the transport equipment driving unit 60. The switch 91 controls the power supply to the transport equipment driving unit 60. The switch 91 is, for example, a mechanical switch that switches between turning on and off power to the transport equipment driving unit 60, and examples of the switch 91 include a magnet contactor and a magnet switch. The opening and closing of the switch 91 is controlled by a switch control unit 92.

[0057] The switch control unit 92 is, for example, an information processing device, and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for transmitting and receiving information to and from other devices, etc. The auxiliary storage device of the switch control unit 92 stores a conveyance current control program for controlling the opening and closing of the switch 91, etc., and the CPU reads out the program stored in the auxiliary storage device into the main memory and executes it to realize various processes described later.

[0058] The transportation energization control program may be stored in advance in an auxiliary storage device such as a ROM when the switch control unit 92 is manufactured, or may be downloaded and installed from a server or the like that distributes the program after construction. Alternatively, the program may be installed via an external storage device. In this manner, there is no particular limitation on the method of installing the various programs.

[0059] The switch control unit 92 is configured to receive a detection signal from, for example, the door full closure detection sensor 67. For example, when the door full closure detection sensor 67 detects that the entrance / exit door 4 has started to open during entry or exit, the switch control unit 92 opens the switch 91 to cut off the power supply to the transport equipment driving unit 60. Also, when the door full closure detection sensor 67 detects that the entrance / exit door 4 has become fully closed during entry or exit, the switch control unit 92 closes the switch 91 to start the power supply to the transport equipment driving unit 60. More specifically, the opening / closing switch control unit 92 opens the opening / closing switch 91 when a door close release signal (off signal) is input from the door fully closed detection sensor 67, and closes the opening / closing switch 91 when a door fully closed signal (on signal) is input from the door fully closed detection sensor 67.

[0060] [Warehousing process] Next, an example of a warehousing process executed by the control device 40 at the time of warehousing will be described with reference to the drawings. Figs. 7 to 9 are flowcharts showing an example of the procedure of the warehousing process executed by the control device 40.

[0061] When entering the vehicle, the user first moves the vehicle 2 in front of the entrance / exit 3, gets off, and heads to the operation panel 22. Then, the user unlocks the vehicle 2 with a special key and opens the lid 44 of the housing 43. When the control device 40 detects that the lid 44 has been opened (SA1 in FIG. 7), it causes the touch panel 45 of the operation panel 22 to display a first user authentication screen (SA2).

[0062] When a user touches an IC card to the IC card reader 46, the user ID (first authentication information) registered in the IC card is read and transmitted to the control device 40. When the user ID is input (SA3), the control device 40 performs a first user authentication (first authentication) to determine whether or not the person attempting to enter the parking lot is a pre-registered user (SA4). Specifically, the control device 40 accesses the general database 52 and determines whether or not the input user ID is registered. As a result, if the first user authentication is unsuccessful (SA5: NO), a message indicating that the user authentication has failed is displayed on the touch panel 45 to notify the user that the authentication has failed, and then the first user authentication screen is displayed (SA2).

[0063] On the other hand, if the first user authentication is successful (SA5: YES), that is, if the user ID is registered in the comprehensive database 52, the system is set to an operation permitted state in which input operations are possible from the touch panel 45 of the operation panel 22 (SA6), the user ID for which the first user authentication was successful is stored in the memory unit 41 (SA7), and a warehousing startup confirmation screen is displayed on the touch panel 45 of the operation panel 22 (SA8).

[0064] When the start button is pressed on the warehousing start confirmation screen (SA9), the control device 40 sets the mechanical mechanisms (storage entry / exit door 4, turntable 8, lift 14, etc.) to an operation permission state (SA10) in which operation is possible, and retrieves an empty pallet from the vehicle storage shelf 17. At this time, a warehousing waiting confirmation screen indicating a warehousing waiting state may be displayed on the touch panel 45.

[0065] Next, when the empty pallet arrives at the boarding / disembarking room 7 and the landing of the lift is detected by the landing detection sensor 34 (SA11), an ON signal is sent from the landing detection sensor 34 to the door current control device 80 (see FIG. 6). Upon receiving the ON signal, the switch control unit 82 of the door current control device 80 closes the switch 81 to start supplying power to the door drive unit 63 (ST1).

[0066] Next, the control device 40 displays a door open screen on the touch panel 45, indicating that the entrance / exit door 4 will open (SA12), and starts opening the door (SA13 in FIG. 8). As the entrance / exit door 4 starts to open, an OFF signal is sent from the door full closure detection sensor 67 to the transport energization control device 90 (see FIG. 6). When the switch control unit 92 of the transport energization control device 90 receives the OFF signal, it opens the switch 91 to cut off the power supply to the transport equipment drive unit 60 (SH1).

[0067] Next, when the full-open door detection sensor (not shown) detects that the loading / unloading door 4 is fully open (SA14), the control device 40 displays an entrance guide screen on the touch panel 45 to encourage the user to enter the storage facility (SA15), and further sets the operation panel 22 to an operation-locked state in which no input is accepted from the touch panel 45 (SA16). This makes it possible to prevent a third party from entering input from the touch panel 45 while the user is away from the operation panel 22.

[0068] After checking the entry information screen, the user gets into vehicle 2, moves vehicle 2 into the boarding / de-boarding compartment, stops vehicle 2 on the empty pallet that has been transported into the boarding / de-boarding compartment, and returns to the front of the operation panel 22. The control device 40 displays a second user authentication screen on the touch panel 45 of the operation panel 22, and prompts the user to input authentication information (SA17).

[0069] As a result, when a user or the like touches an IC card to the IC card reader 46 and inputs authentication information (second authentication information) (SA18), the control device 40 performs a second user authentication (SA19). In the second user authentication (second authentication), it is determined whether or not the received user ID (second authentication information) is a user ID that has been registered in advance. As a result, if the second user authentication is successful (SA19: YES), a comparison process is then performed to determine whether or not the user ID (first authentication information) input in the first user authentication is the same as the user ID (second authentication information) input in the second user authentication (SA20). In the comparison process, it is determined whether or not the person who opened the loading / unloading door 4 is the same as the person who will close it. If the comparison process is successful (SA20: YES), the process proceeds to step SA21.

[0070] On the other hand, if the second user authentication is not successful (SA19: NO) or if the matching process is not successful (SA20: NO), the process returns to step SA17 and the second user authentication screen is displayed. At this time, it is also possible to notify the user that the authentication or matching has failed.

[0071] In step SA21, the control device 40 sets the operation panel 22 to an operation permission state (SA21). Next, the control device 40 displays an unmanned confirmation screen on the touch panel 45 to allow the user to confirm that there is no one in the boarding / deboarding compartment (SA22 in FIG. 9). On the unmanned confirmation screen, for example, an unmanned confirmation button is displayed, and guidance is displayed to encourage the user to confirm that there is no one in the boarding / deboarding compartment before operating the unmanned confirmation button. When the unmanned confirmation button is pressed on this unmanned confirmation screen (SA23), the control device 40 displays a door close screen for closing the entrance / exit door 4 on the touch panel 45 of the operation panel 22 (SA24). On the door close screen, for example, a door close button is displayed, and guidance is displayed to encourage the user to confirm again that there is no one in the boarding / deboarding compartment before operating the door close button.

[0072] When the close door button is pressed on this door closing screen (SA25), the control device 40 starts closing the door (SA26). Then, when the door full closure detection sensor 67 detects that the entrance / exit door 4 is fully closed (SA27), an ON signal is sent from the door full closure detection sensor 67 to the transport power control device 90 (see FIG. 6). When the switch control unit 92 of the transport power control device 90 receives the ON signal, it closes the switch 91 and starts supplying power to the transport equipment driving unit 60 (SH2). Next, the control device 40 starts storing the vehicle (SA28). Specifically, the lift 14 is driven to store the vehicle on a specified storage shelf. As the lift 14 rises, an OFF signal is sent from the floor landing detection sensor 34 to the door current control device 80 (see FIG. 6). Upon receiving the OFF signal, the switch control unit 82 of the door current control device 80 opens the switch 81 and cuts off the power supply to the door drive unit 63 (ST2). Next, when the storage of the vehicle 2 is completed (SA29), the user ID (first authentication information) stored in the memory unit 41 is erased (SA30), and the warehousing process is terminated.

[0073] [Door current control process] Next, an example of a door energization control process executed by the door energization control device 80 during warehousing will be described with reference to the drawings. Fig. 10 is a flowchart showing an example of a process procedure of a door energization control method executed by the door energization control device 80, specifically, the opening / closing switch control unit 82.

[0074] First, when the storage process is started by the control device 40, the switch control unit 82 judges whether or not a floor-landing detection signal (ON signal) has been received from the floor-landing detection sensor 34 (SB1). As a result, if the floor-landing detection signal has not been received (SB1: NO), the switch control unit 82 enters a standby state until the floor-landing detection signal is received. On the other hand, if the floor-landing detection signal has been received (SB1: YES), the switch control unit 82 closes the switch 81 (SB2). This starts the supply of power from the power source 70 (see FIG. 6) to the door drive unit 63 (ST1 state in FIG. 7).

[0075] Next, the switch control unit 82 judges whether or not a landing release signal (OFF signal) has been received from the landing detection sensor 34 (SB3). As a result, if the landing release signal has not been received (SB3: NO), the switch control unit 82 enters a standby state until the landing release signal is received. On the other hand, if the landing release signal has been received (SB3: YES), the switch control unit 82 opens the switch 81 (SB4) and ends this process. This cuts off the power supply from the power source 70 (see FIG. 6) to the door drive unit 63 (state ST2 in FIG. 9).

[0076] [Transport current control process] Next, an example of a transportation energization control process executed by the transportation energization control device 90 at the time of warehousing will be described with reference to the drawings. Fig. 11 is a flowchart showing an example of a processing procedure of a transportation energization control method executed by the transportation energization control device 90, specifically, the switch control unit 92.

[0077] First, when the storage process is started by the control device 40, the switch control unit 92 judges whether or not a door fully closed release signal (OFF signal) has been received from the door fully closed detection sensor 67 (SC1). As a result, if the door fully closed release signal has not been received (SC1: NO), the switch control unit 92 enters a standby state until the door fully closed release signal is received. On the other hand, if the door fully closed release signal has been received (SC1: YES), the switch control unit 92 opens the switch 91 (SC2). This cuts off the power supply from the power source 70 (see FIG. 6) to the transport equipment driving unit 60 (SH1 state in FIG. 8).

[0078] Next, the switch control unit 92 judges whether or not a door fully closed signal (ON signal) has been received from the door fully closed detection sensor 67 (SC3). As a result, if the door fully closed signal has not been received (SC3: NO), the switch control unit 92 enters a standby state until the door fully closed signal is received. On the other hand, if the door fully closed signal has been received (SC3: YES), the switch control unit 92 closes the switch 91 (SC4) and ends this process. This starts the supply of power from the power source 70 (see FIG. 6) to the transport equipment driving unit 60 (state SH2 in FIG. 9).

[0079] [Shipping process] The unloading process is the same as the various processes in the unloading process described above, except that screens specialized for unloading, such as the entry start confirmation screen (SA8 in FIG. 7) and the entry guide screen (SA15 in FIG. 8), are changed to screens specialized for unloading, such as the exit start confirmation screen and the exit guide screen, and that in the pallet calling process, an empty pallet is called when entering the warehouse, whereas a pallet on which a vehicle is placed is called when leaving the warehouse. Therefore, a detailed explanation will be omitted here.

[0080] In addition, the door current control method by the door current control device 80 and the conveyor current control method by the conveyor current control device 90 when leaving the warehouse are the same as when entering the warehouse, so detailed explanations are omitted here.

[0081] As described above, according to this embodiment, it is possible to cut off the power supply to the transport equipment (lift 14, turntable 8, etc.) during a period when there is a possibility that a person may enter the boarding / disembarking room 7. This makes it possible to reliably prevent the transport equipment from being driven during a period when there is a possibility that a person may enter the boarding / disembarking room 7. That is, according to this embodiment, the power supply itself to the transport equipment driving unit 60 that drives the transport equipment is cut off, so it is possible to more reliably prevent the transport equipment from being driven compared to a case where the operation of the transport equipment is locked by software processing. This makes it possible to further improve safety.

[0082] In this embodiment, the switch 91 is opened when the loading / unloading door 4 starts to open, in other words, when a door full-close release signal is notified from the door full-close detection sensor 67, but this is not limited to the above. For example, the switch control unit 92 may open the switch 91 at a predetermined timing from when the transport equipment (e.g., the lift 14) lands on the boarding / deboarding room 7 to when the full-open state of the loading / unloading door 4 is detected. For example, the switch control unit 92 may open the switch 91 when the landing detection sensor 34 detects the landing. Also, the switch control unit 92 may open the switch 91 when the full-open state of the loading / unloading door 4 is detected by the door full-open detection sensor.

[0083] In addition, in this embodiment, the internal detection sensor 30 may be combined with the unoccupied confirmation, and when the internal detection sensor 30 confirms that there is no occupant in the boarding / de-boarding compartment, the switches 81, 91 may be closed. For example, in step SB1 of Figure 10, when a floor landing detection signal is received, the switch control unit 82 determines whether or not the internal detection sensor 30 has detected that the boarding / deboarding room 7 is unoccupied, and if it determines that the boarding / deboarding room 7 is unoccupied, it may close the switch 81.

[0084] Also, for example, when a door fully closed signal is received in step SC3 of FIG. 11, the switch control unit 92 may determine whether or not the internal detection sensor 30 has detected that the boarding / deboarding room 7 is unoccupied, and may close the switch 91 if it is determined that the boarding / deboarding room 7 is unoccupied. Whether the boarding / deboarding compartment 7 is unoccupied may be determined by the switch control units 82, 92 based on a signal from the interior detection sensor 30, or an unoccupied confirmation signal may be input from the main control unit 50 to the switch control units 82, 92. Alternatively, an image captured by the camera 35 may be displayed on the monitor 28 to allow the user to confirm that the boarding / deboarding compartment 7 is unoccupied.

[0085] Second Embodiment Next, a conveyance energization control device, a conveyance energization control method, a conveyance energization control program, and a mechanical parking device according to a second embodiment of the present disclosure will be described with reference to the drawings. In the first embodiment described above, door current control is performed based on a signal from the floor landing detection sensor 34, and transport current control is performed based on a signal from the door full-close detection sensor 67. This embodiment differs in that a signal from the main control unit 50 is reflected in the opening and closing control of the switches 81 and 91. Also, this embodiment differs from the first embodiment in that the opening and closing of the switches 81 and 91 is controlled more finely than in the first embodiment. Hereinafter, the same components as those in the first embodiment described above will be denoted by the same reference numerals and description thereof will be omitted, and different components will be mainly described.

[0086] FIG. 12 is a diagram showing an example of the configuration of the door current control device 80a and the transport current control device 90a according to this embodiment. 12, the switch control unit 82a is configured to receive signals from, for example, the floor landing detection sensor 34, the door fully open detection sensor 66, the door fully closed detection sensor 67, and the main control unit 50. The switch control unit 92a is configured to receive signals from the floor landing detection sensor 34, the door fully closed detection sensor 67, and the main control unit 50.

[0087] [Door current control process] Next, an example of a door current control process executed by the door current control device 80a during warehousing will be described with reference to the drawings. Fig. 13 is a flowchart showing an example of a process procedure of a door current control method executed by the door current control device 80a according to this embodiment, specifically, by the opening / closing switch control unit 82a.

[0088] First, when the storage process is started by the control device 40, the switch control unit 82a judges whether or not a floor-landing detection signal (ON signal) has been received from the floor-landing detection sensor 34 (SD1). As a result, if the floor-landing detection signal has not been received (SD1: NO), the switch control unit 82a enters a standby state until the floor-landing detection signal is received. On the other hand, if the floor-landing detection signal has been received (SD1: YES), the switch control unit 82a closes the switch 91 (SD2). This starts the supply of power from the power source 70 (see FIG. 6) to the door drive unit 63.

[0089] Next, the switch control unit 82a judges whether or not a door fully open signal (ON signal) has been received from the door fully open detection sensor 66 (SD3). As a result, if the door fully open signal has not been received (SD3: NO), the switch control unit 82a enters a standby state until the door fully open signal is received. On the other hand, if the door fully open signal has been received (SD3: YES), the switch control unit 82a opens the switch 81 (SD4). This cuts off the power supply from the power source 70 (see FIG. 12) to the door drive unit 63.

[0090] Next, the switch control unit 82a judges whether or not a door close instruction signal has been received from the main control unit 50 (SD5). This door close instruction signal is a signal output from the main control unit 50 to the door drive unit 63 and the door current control device 80a when a door close instruction is input by the user in step SA25 of FIG. 9, for example. When the switch control unit 82a has not received a door close instruction signal (SD5: NO), it goes into a standby state until it receives a door close instruction signal. On the other hand, when it receives a door close instruction signal (SD5: YES), the switch control unit 82a closes the switch 81 (SD6). This starts the supply of power from the power source 70 (see FIG. 12) to the door drive unit 63.

[0091] Next, the switch control unit 82a judges whether or not a door fully closed signal (ON signal) has been received from the door fully closed detection sensor 67 (SD7). As a result, if the door fully closed signal has not been received (SD7: NO), the switch control unit 82a enters a standby state until the door fully closed signal is received. On the other hand, if the door fully closed signal has been received (SD7: YES), the switch control unit 82a opens the switch 81 (SD8) and ends this process. This cuts off the power supply from the power source 70 (see FIG. 12) to the door drive unit 63.

[0092] According to the above door current control method, for example, when the landing of the lift is detected in step SA11 of Fig. 7, power supply to the door drive unit 63 is started, and when the full opening of the loading / unloading door is detected in step SA14 of Fig. 8, power supply to the door drive unit 63 is cut off. Then, when a door close command is input by the user in step SA25 of Fig. 9 and a door close command signal is received from the main control unit 50, power supply to the door drive unit 63 is started, and when the full closing of the loading / unloading door 4 is detected in step SA27 of Fig. 9, power supply to the door drive unit 63 is cut off.

[0093] [Transport current control process] Next, an example of the transportation energization control process executed by the transportation energization control device 90a at the time of warehousing will be described with reference to the drawing. Fig. 14 is a flowchart showing an example of the processing procedure of the transportation energization control method executed by the transportation energization control device 90a, specifically, the switch control unit 92a.

[0094] First, when the storage process is started by the control device 40, the switch control unit 92a judges whether or not it has received a start permission signal from the main control unit 50 (SE1). This start permission signal is a signal output from the main control unit 50 to the transportation energization control device 90a when, for example, the start button is pressed by the user in step SA9 of FIG. 7 in the storage process of the first embodiment described above. When the switch control unit 92a has not received the start permission signal (SE1: NO), it is in a standby state until it receives the start permission signal. On the other hand, when it has received the start permission signal (SE1: YES), the switch control unit 92a closes the switch 91 (SE2). This starts the supply of power from the power source 70 (see FIG. 12) to the transportation equipment driving unit 60.

[0095] Next, the switch control unit 92a judges whether or not a floor landing detection signal (ON signal) has been received from the floor landing detection sensor 34 (SE3). As a result, if the floor landing detection signal has not been received (SE3: NO), the switch control unit 92a enters a standby state until the floor landing detection signal is received. On the other hand, if the floor landing detection signal has been received (SE3: YES), the switch control unit 92a opens the switch 91 (SE4). Next, the opening / closing switch control unit 92a judges whether or not a door fully closed signal (ON signal) has been received from the entrance / exit door sensor 65 (SE5). As a result, if the door fully closed signal has not been received (SE5: NO), the opening / closing switch control unit 92a waits until the door fully closed signal is received. On the other hand, if the door fully closed signal has been received (SE5: YES), the opening / closing switch control unit 92a closes the opening / closing switch 91 (SE6). Next, the switch control unit 92a judges whether or not a storage completion signal has been received from the main control unit 50 (SE7). This storage completion signal is a signal output from the main control unit 50 to the transportation energization control device 90a when the storage of the vehicle is completed in step SA29 of FIG. 9 in the warehousing process of the first embodiment described above. When the storage completion signal has not been received (SE7: NO), the switch control unit 92a enters a standby state until the storage completion signal is received. On the other hand, when the storage completion signal is received (SE7: YES), the switch control unit 92a releases the switch 91 (SE8) and ends this process. This causes the power supply from the power source 70 (see FIG. 12) to the transportation equipment driving unit 60 to be cut off.

[0096] According to the above-mentioned transport power control method, for example, when a start button is pressed by a user in step SA9 in Fig. 7 and a start permission signal is received from the main control unit 50, power supply to the transport equipment driving unit 60 is started, and when the landing of the lift 14 is detected in the following step SA11, power supply to the transport equipment driving unit 60 is cut off. Then, when the full closure of the loading / unloading door 4 is detected in step SA27 in Fig. 9, power supply to the transport equipment driving unit 60 is started, and when a storage completion signal is received from the main control unit 50 in the following step SA29, power supply to the transport equipment driving unit 60 is cut off.

[0097] As described above, according to this embodiment, the opening and closing control of the switches 81 and 91 is performed more precisely than in the first embodiment. This makes it possible to reduce power consumption.

[0098] In the present embodiment, in addition to the main control unit 50, detection signals from various sensors are input to the switch control units 82a, 92a, but this is not limiting. For example, the detection signals from the various sensors may also be input to the switch control units 82a, 92a via the main control unit 50.

[0099] Furthermore, the timing for cutting off the power supply to the door drive unit 63 is not limited to the above example. For example, the switch control unit 82 may be configured to open the switch 81 at a predetermined timing during the period from when the full opening of the loading / unloading door 4 is detected by the door full-open detection sensor 66 to when the landing detection sensor 34 no longer detects landing.

[0100] Furthermore, the timing for starting the supply of power to the door drive unit 63 is not limited to the above example. For example, the switch control unit 82 may be configured to close the switch 81 at a predetermined timing during the period from when the unattended vehicle is confirmed (for example, SA23 in FIG. 9) until the main control unit 50 starts closing the entrance / exit door 4 (for example, SA26 in FIG. 9).

[0101] In addition, in this embodiment, the internal detection sensor 30 may be combined with the unoccupied confirmation, and when the internal detection sensor 30 confirms that there is no occupant in the boarding / de-boarding compartment, the switches 81, 91 may be closed. For example, when a floor landing detection signal is received in step SD1 of FIG. 13, or when a door close instruction signal is received in step SD5, the switch control unit 82a may determine whether or not the internal detection sensor 30 has detected that the boarding / deboarding room 7 is unoccupied, and if it determines that the boarding / deboarding room 7 is unoccupied, close the switch 81.

[0102] Also, for example, when a start permission signal is received in step SE1 of FIG. 14, or when a door fully closed signal is received in step SE5, the switch control unit 92a may determine whether or not the internal detection sensor 30 has detected that the boarding / deboarding room 7 is unoccupied, and may close the switch 91 if it is determined that the boarding / deboarding room 7 is unoccupied. In addition, the determination that the boarding / disembarkation room 7 is unoccupied may be made by the switch control units 82a, 92a based on a signal from the internal detection sensor 30, or an unoccupied confirmation signal may be input from the main control unit 50 to the switch control units 82a, 92a.

[0103] [Modifications] For example, the door current control devices 80, 80a and the conveyor current control devices 90, 90a may be configured to be able to communicate with each other. In this case, the door current control devices 80, 80a and the conveyor current control devices 90, 90a notify each other of the timing to open and close the switches 81, 91, thereby avoiding a state in which the switches 81 and 91 are both in a closed state. This allows the switch 91 to be in an open state during a period in which the switch 81 is closed, and similarly, allows the switch 81 to be in an open state during a period in which the switch 91 is closed. This makes it possible to further improve safety.

[0104] Also, a configuration may be adopted in which an operation signal of an emergency stop button provided in the boarding / disembarking room 7 or on the operation panel 22 is input to the door current control devices 80, 80a and the transport current control devices 90, 90a. When the emergency stop button is operated, the door current control devices 80, 80a and the transport current control devices 90, 90a may open the switches 81, 91 to cut off the power supply to the door drive unit 63 and the transport equipment drive unit 60.

[0105] Although one each of the switches 81 and 91 is provided, the number of switches to be provided is not limited. For example, the switches 81 and 91 may each be configured with a plurality of switches connected in series. In this way, even if one switch breaks down, the other switches are opened, so that the power supply can be reliably cut off.

[0106] In addition, the door current control devices 80, 80a and the conveyor current control devices 90, 90a are provided as separate control devices from the control device 40, but this is not limited to the above. For example, the control device 40 may be configured to have at least one of the functions of the door current control devices 80, 80a and the conveyor current control devices 90, 90a.

[0107] Third Embodiment Next, a conveyance energization control device, a conveyance energization control method, a conveyance energization control program, and a mechanical parking device according to a third embodiment of the present disclosure will be described with reference to the drawings. In the above-mentioned first and second embodiments, an elevator-type mechanical parking device 1 in which a pallet 18 is conveyed by a lift 14 between a boarding / deboarding room 7 and a vehicle storage shelf 17 is illustrated, but in this embodiment, a flat reciprocating-type mechanical parking device 100 in which a vehicle is handed over by a conveyor is illustrated.

[0108] Fig. 15 is a perspective view showing a schematic structure of the mechanical parking device 100 according to this embodiment. As shown in Fig. 15, the mechanical parking device 100 includes, for example, a plurality of multi-row storage shelf groups 110. In the multi-row storage shelf group 110, a plurality of storage shelves 112 for storing vehicles 2 are arranged in succession. A lateral feed conveyor 117 is provided on each storage shelf 112. One or more trolleys 105 are provided in the passage (trolley running path) between each of the multi-row storage shelf groups 110. The trolleys 105 can run along the multi-row storage shelf groups 110 by running on rails, for example. Note that the multi-row storage shelf groups 110 have a hierarchical structure, and correspondingly, the trolleys 105 are provided on each floor. The trolleys 105 are provided with a lateral feed conveyor 116 for transporting the vehicles 2 laterally.

[0109] In the group of double-row storage shelves 110, a berth (boarding and disembarking room) 102 for loading and unloading is provided on the loading / unloading floor. The berth 102 is provided next to a lift elevator room 101 where a lift 103 ascends and descends. The berth 102 is provided with a lateral feed conveyor 114 (see FIG. 16). In addition, the lift 103 is provided with a lateral feed conveyor 115. Fig. 16 is a schematic external view of a berth (boarding and disembarking room) 102, and Fig. 17 is a schematic plan view of the berth 102. As shown in Figs. 16 and 17, a partition door 104 is provided between the berth 102, which also serves as a boarding and disembarking room, and the lift ascending and descending room 101.

[0110] As shown in Fig. 17, an automatic door 123 is provided on the parking lot entrance / exit SP side of the berth 102. This automatic door 123 is an entrance / exit door used when people move between the berth 102 and the parking lot entrance / exit SP. An operation panel 125 is provided on the parking lot entrance / exit SP side. This operation panel 125 is preferably provided near the automatic door 123 in a location where the inside of the berth 102 can be seen.

[0111] A plurality of cameras (not shown) are installed at each location of the berth 102. The plurality of cameras are controlled by a control device 130 (see FIG. 18), which will be described later. Furthermore, an interior detection sensor (not shown) may be installed at each location of the berth 102 to check whether there is anyone inside. The interior detection sensor makes it possible to detect people and the like inside the berth, as well as the position of a vehicle, and the like.

[0112] The configuration of the mechanical parking device 100 in this embodiment is just an example, and other known configurations can be adopted.

[0113] Fig. 18 is a schematic diagram showing the electrical configuration of this embodiment. As shown in Fig. 18, the mechanical parking device 100 includes a control device 130, a berth power supply control device 180, and a transportation power supply control device 190. The control device 130 controls the entire mechanical parking device 100. The control device 130 is composed of, for example, a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and a computer-readable storage medium (not shown). A series of processes for realizing various functions is stored in a storage medium or the like in the form of a program (for example, a control program for the mechanical parking device, etc.), and the CPU reads this program into the RAM or the like and executes information processing and arithmetic processing to realize various processes such as a parking entry process and a parking exit process (described later). The program may be installed in a ROM or other storage medium in advance, provided in a state stored in a computer-readable storage medium, or distributed via a wired or wireless communication means. The computer-readable storage medium may be a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc.

[0114] The control device 130 controls, for example, a berth drive unit 140 that drives equipment provided on the berth 102, a lift drive unit 150 that raises and lowers the lift (transport equipment) 103, a cart drive unit 160 that runs the cart 105, etc. Furthermore, the control device 130 controls, for example, a lateral feed drive unit (not shown) that drives the lateral feed conveyors 115, 116, and 117. The berth driving unit 140 includes, for example, a door driving unit 141 that opens and closes the compartment door 104. Furthermore, the berth driving unit 140 may include a transverse feed driving unit 142 that drives the transverse conveyor 114.

[0115] The berth energization control device 180 includes a switch (berth switch) 181 and a switch control section (berth switch control means) 182. The transport energization control device 190 includes a switch 191 and a switch control section (switch control means) 192.

[0116] Power is supplied to the berth drive unit 140, the lift drive unit 150, and the cart drive unit 160 from a power source 200. A breaker 120 is provided in the electric circuit connecting the power source 200 and the berth drive unit 140, a breaker 121 is provided in the electric circuit connecting the power source 200 and the lift drive unit 150, and a breaker 122 is provided in the electric circuit connecting the power source 200 and the cart drive unit 160.

[0117] In the event of an abnormality such as an overcurrent, the breakers 120 to 122 are activated to cut off the power supply to the berth drive unit 140, the lift drive unit 150, and the cart drive unit 160. After safety is confirmed by an operator, the breakers 120 to 122 are restored by the operator and the power is turned on again.

[0118] A switch 181 is provided on an electric circuit connecting the power source 200 and the berth drive unit 140, downstream of the breaker 120, in other words, closer to the berth drive unit 140. The switch 181 controls the power supply to the berth drive unit 140. The switch 181 is, for example, a mechanical switch that switches between turning on and off power to the berth drive unit 140, and examples of the switch 181 include a magnet contactor and a magnet switch. The opening and closing of the switch 181 is controlled by a switch control unit 182.

[0119] The switch control unit 182 is, for example, an information processing device, and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for transmitting and receiving information to and from other devices, etc. The auxiliary storage device of the switch control unit 182 stores a bus current control program for controlling the opening and closing of the switch 181, etc., and the CPU reads out the program stored in the auxiliary storage device into the main memory and executes it to realize various processes described later.

[0120] The berth energization control program may be stored in advance in an auxiliary storage device such as a ROM when the switch control unit 182 is manufactured, or may be downloaded and installed from a server or the like that distributes the program after construction. Alternatively, the program may be installed via an external storage device. In this way, there is no particular limitation on the method of installing the various programs.

[0121] When the lift 103 arrives at the boarding floor where the berth 102 is provided, for example, when entering or leaving the warehouse, the switch control unit 182 closes the switch 181 to start the power supply to the berth drive unit 140. When the movement of the vehicle 2 from the berth 102 to the lift 103 is completed and the transportation of the lift 103 is started, for example, when entering or leaving the warehouse, the switch control unit 182 opens the switch 181 to cut off the power supply to the berth drive unit 140. More specifically, the lift boarding room 101 is provided with a lift boarding room sensor 171 for detecting that the lift 103 has arrived at the boarding room floor. A known sensor can be appropriately adopted as the lift boarding room sensor 171. For example, a limit switch or the like can be given as an example of the lift boarding room sensor 171. The switch control unit 182 closes the switch 181 when an on signal (arrival detection signal) is output from the lift boarding / disembarking space sensor 171, and opens the switch 181 when an off signal (arrival release signal) is output from the lift boarding / disembarking space sensor 171.

[0122] A switch 191 is provided on an electric circuit connecting the power source 200 and the lift driving unit 150, downstream of the breaker 121, in other words, closer to the lift driving unit 150. The switch 191 controls the power supply to the lift driving unit 150. The switch 191 is, for example, a mechanical switch that switches between turning on and off power to the lift driving unit 150, and examples of the switch 191 include a magnet contactor and a magnet switch. The opening and closing of the switch 191 is controlled by a switch control unit 192.

[0123] The switch control unit 192 is, for example, an information processing device, and includes a CPU, an auxiliary storage device for storing programs executed by the CPU, a main memory that functions as a work area when each program is executed, a communication interface for transmitting and receiving information to and from other devices, etc. The auxiliary storage device of the switch control unit 192 stores a conveyance current control program for controlling the opening and closing of the switch 191, etc., and the CPU reads out the program stored in the auxiliary storage device into the main memory and executes it to realize various processes described later.

[0124] The transportation energization control program may be stored in advance in an auxiliary storage device such as a ROM when the switch control unit 192 is manufactured, or may be downloaded and installed from a server or the like that distributes the program after construction. Alternatively, the program may be installed via an external storage device. In this way, there is no particular limitation on the method of installing the various programs.

[0125] The switch control unit 192 is configured to receive a detection signal from the door full closure detection sensor 172. For example, when the compartment door 104 starts to open during entry or exit, the switch control unit 192 opens the switch 191 to cut off the power supply to the lift drive unit 150. Also, for example, when the compartment door 104 is in a fully closed state during entry or exit, the switch control unit 192 closes the switch 191 to start the power supply to the lift drive unit 150. For example, the switch control unit 192 closes the switch 191 when an ON signal (door full closure signal) is output from the door full closure detection sensor 172, and opens the switch 191 when an OFF signal (door full closure release signal) is output from the door full closure detection sensor 172.

[0126] [Warehousing process] Next, the control of the berth energization control device 180 and the transport energization control device 190 when the mechanical parking device 100 according to this embodiment enters a parking space will be described with reference to Fig. 19. Fig. 19 is a diagram showing an example of the procedure of the parking entry process according to this embodiment. First, the user stops the vehicle 2 at a predetermined stopping position within the berth 102, gets off, and exits through the automatic door 123. When the user exits the berth 102, the operator inputs authentication information by holding an IC card over the IC card reader of the operation panel 125. When the control device 130 of the mechanical parking device 100 receives the authentication information from the operation panel 125, it makes a reservation for entry.

[0127] The control device 130 drives the lift drive unit 150 to raise and lower the lift 103 toward the berth 102. In addition, the control device 130 drives the cart drive unit 160 to move the cart 105 from the lift 103 to a receiving position where the cart can be received. When the lift 103 arrives at the boarding floor, the lift boarding / disembarking compartment sensor 171 is turned on, and an arrival detection signal (on signal) is output to the switch control unit 182. When the switch control unit 182 receives the arrival detection signal, it closes the switch 181 and starts supplying power to the berth drive unit 140 (SH1).

[0128] On the other hand, when a user confirms that no one is present in the berth 102 and presses the no-person confirmation button on the operation panel 125, the operator then performs a safety check and presses the safety confirmation button on the operation panel 125. Upon receiving the pressing of the safety confirmation button, the control device 130 drives the door drive unit 141 to open the compartment door 104. As a result, a door full-close release signal (off signal) is output from the door full-close detection sensor 172 to the switch control unit 192. Upon receiving the door full-close release signal, the switch control unit 192 opens the switch 191 and cuts off the power supply to the lift drive unit 150 (SH2).

[0129] Next, when a door full-open sensor (not shown) detects that the compartment door 104 is fully open, the control device 130 drives the lateral feed drive unit 142. As a result, the vehicle 2 is lateral-handed over to the lift 103 by the lateral feed conveyor 114. When the movement of the vehicle 2 onto the lift 103 is completed, the control device 130 closes the compartment door 104. Then, the compartment door 104 is completely closed, and a door full-close detection signal (ON signal) is output from the door full-close detection sensor 172 to the opening / closing switch control unit 192. When the opening / closing switch control unit 192 receives the door full-close detection signal, it closes the opening / closing switch 191 and starts supplying power to the lift drive unit 150 (SH3).

[0130] Next, the control device 130 drives the lift driving unit 150 to move the lift 103 to the storage floor. As a result, an arrival release signal (off signal) is output from the lift boarding / alighting compartment sensor 171 to the switch control unit 182. Upon receiving the arrival release signal, the switch control unit 182 opens the switch 181 to cut off the power supply to the berth driving unit 140 (SH4). When it is detected that the lift 103 has reached the storage floor, the control device 130 drives a lateral feed drive unit (not shown) of the lateral feed conveyor 115 provided on the lift 103. As a result, the vehicle 2 is lateral-handed over to the trolley 105 that has been waiting for interlocking at the storage floor. Next, the control device 130 drives the trolley drive unit 160 to move the trolley 105 to a predetermined storage shelf 112. Then, the control device 130 drives a lateral feed drive unit (not shown) of the lateral feed conveyor 116 provided on the trolley 105 and a lateral feed drive unit (not shown) of the lateral feed conveyor 117 provided on the storage shelf 112, thereby storing the vehicle 2 in the predetermined storage shelf 112, and completing the warehousing process.

[0131] [Shipping process] For the leaving process, the movement route of the vehicle 2 is reversed from that for entering the shed, and the main process is the same. Therefore, a detailed explanation will be omitted here. In addition, the berth energization control method by the berth energization control device 180 and the lift energization control method by the transport energization control device 190 at the time of leaving the shed are also the same as those at the time of entering the shed, so a detailed explanation will be omitted here.

[0132] As described above, the transport current control device 190 according to this embodiment makes it possible to cut off the power supply to the lift (transport equipment) 103 when the compartment door 104 is open. This makes it possible to reliably prevent the lift 103 from being driven when the compartment door 104 is open. That is, according to this embodiment, the power supply itself to the lift drive unit 150 that drives the lift 103 is cut off, so it is possible to more reliably prevent the lift 103 from being driven compared to a case where the operation of the lift 103 is locked by software processing. This makes it possible to further improve safety.

[0133] Furthermore, the berth power control device 180 according to this embodiment makes it possible to cut off the power supply to the berth drive unit 140 while the lift 103 is moving. This makes it possible to reliably prevent the compartment door 104, the lateral conveyor 114, etc. from being driven while the lift 103 is moving. That is, according to this embodiment, the power supply itself to the berth drive unit 140 that drives the compartment door 104, the lateral conveyor 114, etc. is cut off, making it possible to more reliably prevent these devices from being driven compared to a case in which the operation of these devices is locked by software processing. This makes it possible to further improve safety.

[0134] [Fourth embodiment] Next, a conveyance energization control device, a conveyance energization control method, a conveyance energization control program, and a mechanical parking device according to a fourth embodiment of the present disclosure will be described with reference to the drawings. In the above-mentioned third embodiment, berth energization control is performed based on a signal from the lift boarding / deboarding chamber sensor 171, and transport energization control is performed based on a signal from the door full-closure detection sensor 172. This embodiment differs in that signals from the lift boarding / deboarding chamber sensor 171, the door full-closure detection sensor 172, and the control device 130 are reflected in the opening and closing control of the switches 181 and 191. This embodiment also differs in that the opening and closing of the switch 191 is controlled more precisely than in the third embodiment. Hereinafter, the same components as those in the above-described third embodiment will be denoted by the same reference numerals and description thereof will be omitted, and different components will be mainly described.

[0135] Fig. 20 is a schematic diagram showing the electrical configuration according to this embodiment. As shown in Fig. 20, the switch control unit 182a is configured to receive signals from the lift boarding / deboarding chamber sensor 171 and the control device 130. The switch control unit 192a is configured to receive signals from the door full-close detection sensor 172 and the control device 130.

[0136] [Warehousing process] Next, the control of the berth energization control device 180a and the transport energization control device 190a when the mechanical parking device 100 according to this embodiment enters a parking space will be described with reference to Fig. 21. Fig. 21 is a diagram showing an example of the procedure of the parking entry process according to this embodiment.

[0137] First, up to the warehousing reservation, the description will be omitted since it is the same as the third embodiment described above. When the warehousing reservation is made, the control device 130 outputs a lift start instruction signal to the switch control unit 192a. When the switch control unit 192a receives the lift start instruction signal, it closes the switch 191 and starts supplying power to the lift driving unit 150 (SJ1). The control device 130 drives the lift driving unit 150 to raise and lower the lift 103 toward the berth 102. In addition, the control device 130 controls the cart driving unit 160 to move the cart 105 to a receiving position where the vehicle can be received from the lift 103. When the lift 103 arrives at the boarding floor, the lift boarding / disembarking compartment sensor 171 is turned on, and an arrival detection signal (on signal) is output to the switch control unit 182a. When the switch control unit 182a receives the arrival detection signal, it closes the switch 181 and starts supplying power to the berth drive unit 140 (SH1).

[0138] On the other hand, when a user confirms that no one is present in the berth 102 and presses the no-person confirmation button on the operation panel 125, the operator then performs a safety check and presses the safety confirmation button on the operation panel 125. Upon receiving the pressing of the safety confirmation button, the control device 130 drives the door drive unit 141 to open the compartment door 104. This turns off the door full-close detection sensor 172, and a door full-close release signal (off signal) is output to the switch control unit 192a. Upon receiving the door full-close release signal, the switch control unit 192a opens the switch 191 and cuts off the power supply to the lift drive unit 150 (SH2).

[0139] Next, when a door full-open sensor (not shown) detects that the compartment door 104 is fully open, the control device 130 drives the lateral feed drive unit 142. As a result, the vehicle 2 is lateral-handed over to the lift 103 by the lateral feed conveyor 114. When the control device 130 has completed moving the vehicle 2 onto the lift 103, it drives the door drive unit 141 to close the compartment door 104. Then, the compartment door 104 is completely closed, and a door full-close detection signal (on signal) is output from the door full-close detection sensor 172 to the opening / closing switch control unit 192a. When the opening / closing switch control unit 192a receives the door full-close detection signal, it closes the opening / closing switch 191 and starts supplying power to the lift drive unit 150 (SH3). Next, the control device 130 drives the lift driving unit 150 to move the lift 103 to the storage floor. As a result, an arrival release signal (off signal) is output from the lift boarding / alighting compartment sensor 171 to the switch control unit 182a. Upon receiving the arrival release signal, the switch control unit 182a opens the switch 181 to cut off the power supply to the berth driving unit 140 (SH4).

[0140] When it is detected that the lift 103 has reached the storage floor, the control device 130 drives a lateral feed drive unit (not shown) of the lateral feed conveyor 115 provided on the lift 103. This causes the vehicle 2 to be lateral-handed over to the trolley 105 that has been waiting for interlocking at the storage floor. Next, when the control device 130 has completed the movement of the vehicle 2 from the lift 103 to the trolley 105, it outputs a trolley movement completion signal to the switch control unit 192a. On receiving the trolley movement completion signal, the switch control unit 192a opens the switch 191 and cuts off the power supply to the lift drive unit 150 (SJ2). Next, the control device 130 drives the cart drive unit 160 to move the cart 105 to a predetermined storage shelf 112. Then, the control device 130 drives a lateral feed drive unit (not shown) of the lateral feed conveyor 116 provided on the cart 105 and a lateral feed drive unit (not shown) of the lateral feed conveyor 117 provided on the storage shelf 112 to store the vehicle 2 in the predetermined storage shelf 112, and the warehousing process is completed.

[0141] [Shipping process] For the leaving process, the movement route of the vehicle 2 is reversed from that for entering the shed, and the main process is the same. Therefore, a detailed explanation will be omitted here. In addition, the berth energization control method by the berth energization control device 180a and the lift energization control method by the transport energization control device 190a at the time of leaving the shed are also the same as those at the time of entering the shed, so a detailed explanation will be omitted here.

[0142] As described above, according to this embodiment, the opening and closing control of the switch 191 is performed more precisely than in the third embodiment, so that it is possible to control the supply and cut-off of power to the lift driving unit 150 at appropriate timing according to the entering and leaving situation. As a result, it is possible to improve safety and reduce power consumption.

[0143] In the above-described third and fourth embodiments, the bogie drive unit 160 is always energized, but this is not limited thereto. For example, a switch may be provided between the breaker 122 and the bogie drive unit 160 to control the energization of the bogie drive unit 160. For example, as shown in FIG. 22, when a lift start instruction signal is received from the control device 130, the switch may be closed to start the supply of power to the bogie drive unit 160 (SK1), and when a storage shelf movement completion signal is received from the control device 130 due to the completion of the transfer of the vehicle 2 from the bogie 105 to the storage shelf 112, the switch may be opened to cut off the supply of power to the bogie drive unit 160 (SK2).

[0144] In the third embodiment described above, signals from the lift boarding / deboarding chamber sensor 171 and the control device 130 are input to the opening / closing control unit 182a, and signals from the door full-closure detection sensor 172 and the control device 130 are input to the opening / closing control unit 192a, but this is not limiting. For example, signals from the lift boarding / deboarding chamber sensor 171 and the door full-closure detection sensor 172 may also be input via the control device 130.

[0145] Furthermore, the timing for opening and closing the switches 181, 191 in the third and fourth embodiments described above is not limited to the above examples, and the opening and closing of these switches 181, 191 may be controlled at other timings. For example, the switch control unit 182a may close the switch 181 at a predetermined timing from when an arrival detection signal (ON signal) is output from the lift boarding / disembarking compartment sensor 171 until when safety within the berth 102 is confirmed. Here, the time when safety within the berth 102 is confirmed may be, for example, when an unmanned confirmation or safety confirmation is input by a user or operator as described above, or when safety within the berth 102 is confirmed by an internal detection sensor (for example, a human presence sensor, a vehicle position detection sensor, a range sensor, a camera, etc.) installed in the berth 102.

[0146] In addition, the opening / closing switch control unit 182a may open the opening / closing switch 181 at a predetermined timing from when the fully open door 104 is detected by the full-open door detection sensor (not shown) to when an arrival release signal (off signal) is output from the lift boarding / disembarking chamber sensor 171.

[0147] Also, for example, the switch control unit 192a may open the switch 191 at a predetermined timing from when the lift boarding / deboarding compartment sensor 171 outputs an arrival detection signal (ON signal) until the full opening of the compartment door 104 is detected and the full opening door sensor outputs a full closing door detection signal (ON signal). This makes it possible to extend the off period and reduce power consumption.

[0148] In addition, the berth energization control devices 180, 180a and the transport energization control devices 190, 190a are provided as control devices separate from the control device 130, but this is not limited to the above. For example, the control device 130 may be configured to have the functions of the berth energization control devices 180, 180a and the transport energization control devices 190, 190a.

[0149] The present disclosure has been described above using the above embodiment, but the technical scope of the present disclosure is not limited to the scope described in the above embodiment. Various changes or improvements can be made to the above embodiment without departing from the gist of the disclosure, and forms with such changes or improvements are also included in the technical scope of the present disclosure. In addition, the flows of the warehousing process, warehousing process, door energization control process, transport energization control process, berth energization control process, etc. described in the above embodiment are examples, and it is possible to delete unnecessary steps, add new steps, or change the order of processes without departing from the gist of the present disclosure.

[0150] For example, the entrance / exit door 4 and the compartment door 104 are described as upward-opening doors, but are not limited thereto. For example, the entrance / exit door 4 and the compartment door 104 may be horizontally opening doors or downward opening doors (types that are stored on the ground).

[0151] The conveying energization control device, the conveying energization control method, the conveying energization control program, and the mechanical parking device described in each of the embodiments described above can be understood, for example, as follows.
