That is, the present invention is not limited to the dimensional ratio in the drawings.

(Example 1)
FIG. 1 is a perspective view of a parking device 10 according to an embodiment of the present invention, and FIG. 2 is a schematic front view of the parking device 10. As shown in FIG. 1, the parking device 10 of the present embodiment is a fork type multistory parking lot (device). With reference to FIG.1 and FIG.2, the mechanical structure and operation | movement of the fork type multi-story parking apparatus 10 of one Embodiment are demonstrated.

  As shown in FIGS. 1 and 2, the parking apparatus 10 includes a boarding place 11 disposed on the ground surface, a lifting space 13 connected vertically upward from the boarding place 11, and left and right sides of the lifting space 13. It is a mechanical multi-story parking lot provided with a plurality of parking rooms 20 arranged on a plurality of floors. The boarding place 11 is arranged on the ground floor so that the vehicle V can enter or leave, and includes a boarding base 11a and a recessed portion 11b below the boarding base 11a. The boarding board 11a has a comb-teeth shape (not shown) in which comb teeth extend from the center frame to the left and right outwards.

  The elevating space 13 is defined by four guide rails 13a extending vertically, and is a space for elevating the elevating lift 12. The height of the elevating space 13 (guide rail 13a) is arbitrarily set according to the desired number of parking rooms 20, that is, the number of floors of the parking tower. The lifting lift 12 has a mounting surface 12a on which the vehicle V is loaded. The mounting surface 12a is composed of a frame divided into a pair of left and right, and comb teeth extend inward from the outer frame. The comb teeth of the mounting surface 12 a and the comb teeth of the boarding base 11 a are formed so as to be able to pass each other, and the mounting surface 12 a is movable in the recessed portion 11 b of the boarding place 11. That is, the boarding platform 11a and the lift lift 12 can pass the vehicle V to each other.

  The elevating space 13 is provided with an elevating drive unit 14 for elevating the elevating lift 12. The elevating drive unit 14 includes a drive motor 15, a pulley 16, a cord-like body 17, and a balance weight 18. The drive motor 15 and the pulley 16 are installed in the top part of the raising / lowering space 13, and the drive motor 15 is arrange | positioned so that the pulley 16 can be rotationally driven. A plurality of long cords 17 are wound around the pulley 16. The cord-like body 17 is disposed inside the four guide rails 13a and is suspended in the vertical direction along the guide rails 13a. One end of the cord-like body 17 is connected to the lifting lift 12 and the other end of the cord-like body 17 is connected to the balance weight 18. That is, when the pulley 16 rotates in one direction, the lifting lift 12 is raised and the balance weight 18 is lowered via the cord-like body 17. On the other hand, when the pulley 16 rotates in the other direction, the lifting / lowering lift 12 is lowered and the balance weight 18 is raised via the cord-like body 17. The lift 12 can be lifted from the top floor to the ground floor in the lift space 13.

  The weight of the balance weight 18 is set so as to be heavier than the weight of the lift lift 12 and lighter than the total weight of the lift lift 12 and the mounting vehicle V. In this embodiment, the lifting lift 12 has a weight of about 500 kg to about 700 kg, and the balance weight 18 has a weight of about 1200 kg to about 1700 kg. On the other hand, the weight of a light vehicle is about 700 kg to about 1000 kg. The weight of the balance weight 18 is determined so as not to exceed the sum of the weight of the lifting lift 12 and the weight of the light vehicle. That is, the parking apparatus 10 of the present embodiment is configured to be able to handle the entry and exit of light vehicles. However, the weight of the balance weight 18 can be optimized arbitrarily according to the type of the vehicle V to be parked.

  Moreover, each parking room 20 is arrange | positioned adjacent to the raising / lowering space 13 in each floor. Each parking room 20 is a space in which one vehicle V can be parked. A transverse tray 21 on which the vehicle V is placed is disposed in the parking room 20. The traverse tray 21 has a comb-teeth shape in which comb teeth extend from the center frame to the left and right outwards. The traverse tray 21 is formed so as to be able to pass the comb-teeth mounting surface 12a of the lift lift 12 described above. That is, the lift 12 and the traverse tray 21 can pass the vehicle V to each other. A transverse rail 22 extends between the elevating space 13 and each parking room 20. The transverse tray 21 reciprocates between the parking room 20 and the elevating space 13 along the transverse rail 22. The front and rear ends of the traversing tray 21 are supported by a plurality of driving rollers 22a formed on the traversing rail 22, and are traversed by the rotation of the driving rollers 22a. The plurality of drive rollers 22 a are rotationally driven by a traverse motor 23.

  Next, a series of mechanical operations for placing the vehicle V in the parking device 10 and parking in the predetermined parking room 20 will be described. When the lift 12 is positioned on the ground floor in the initial state, the mounting surface 12 a is accommodated in the recessed portion 11 b of the boarding place 11. Then, when the vehicle V gets into the boarding place 11 and is placed on the boarding platform 11a, when the lift 12 is raised, the comb-like placement surface 12a and the comb-like boarding platform 11a Pass each other, and the vehicle V is transferred from the boarding board 11a to the mounting surface 12a. The lift lift 12 loaded with the vehicle V is pulled up above the traverse rail 22 of the predetermined parking chamber 20, and the traverse tray 21 traverses in the lift space 13 and is disposed below the lift lift 12. Then, the lift lift 12 is lowered, and the comb-shaped mounting surface 12 a and the comb-shaped traverse tray 21 pass each other, whereby the vehicle V is transferred from the lift lift 12 to the traverse tray 21. After the transfer, the traversing tray 21 on which the vehicle V is mounted traverses the parking chamber 20 along the traversing rail 22, whereby the vehicle V is accommodated in the parking chamber 20.

  On the other hand, when the vehicle V is discharged from the predetermined parking chamber 20, the traversing tray 21 on which the vehicle V is mounted traverses from the parking chamber 20 to the lifting / lowering space 13 and the empty lift 12 is lifted. Then, the placing surface 12a of the lift 12 is raised so as to pass the transverse tray 21, stops above the transverse tray 21, and the vehicle V is transferred from the transverse tray 21 to the placing surface 12a. Next, the empty traversing tray 21 traverses and is accommodated in the parking room 20. Subsequently, the lift lift 12 in the loaded state descends to the ground floor, and the vehicle V is placed at the boarding place 11. And the mounting surface 12a passes the boarding base 11a, and is accommodated in the recessed part 11b, and the vehicle V is transferred from the mounting surface 12a to the boarding base 11a.

  In this embodiment, when raising / lowering the lifting lift 12, the drive motor 15 is comprised so that a power running operation or a regenerative operation may be performed. The drive motor 15 needs to be supplied with power by the power supply 31 or the power storage device 32 when performing a power running operation. On the other hand, the drive motor 15 is reversely driven by the pulley 16 to perform a regenerative operation. In this regenerative operation, the drive motor 15 functions as a generator, and regenerative power is generated. The regenerative power of the drive motor 15 can be stored in the power storage device 32.

  Then, when the lifted lift 12 loaded with the vehicle V is raised, the drive motor 15 performs a power running operation to compensate for the difference between the weight of the lifted lift 12 in the loaded state and the weight of the balance weight 18, and the pulley 16. Is lifted to raise the lift lift 12. When the lift lift 12 in an empty state without the vehicle V is raised, the balance weight 18 (heavier than the lift lift 12) is lowered in the vertical direction by its own weight (gravity). Rotation drives the drive motor 15, and the drive motor 15 performs a regenerative operation. Further, when the loaded lift lift 12 mounted with the vehicle V is lowered, the loaded lift lift 12 (heavier than the balance weight 18) is lowered by its own weight in the vertical direction, whereby the rotation of the pulley 16 causes the drive motor 15 to rotate. And the drive motor 15 performs a regenerative operation. When the empty lift lift 12 that is not mounted with the vehicle V is lowered, the drive motor 15 performs a power running operation to compensate for the difference between the weight of the balance weight 18 and the weight of the lift lift 12 in the empty condition. And the balance weight 18 is pulled up.

  FIG. 3 is a schematic configuration diagram of the parking apparatus 10. With reference to FIG. 3, the control system of the parking apparatus 10 is demonstrated.

  The parking apparatus 10 according to the present embodiment is powered by a commercial power supply 31 of AC 200V. The commercial power supply 31 can supply a predetermined allowable power amount, and the allowable power amount is determined by a contract with an electric power company. The commercial power supply 31 is connected to a converter 36a, and the converter 36a temporarily converts AC power into DC power. The converter 36a is electrically connected to an inverter 36b, an inverter 36c, a DC / DC converter 36d, and a resistor 36e via a DC bus line. When the power supply from the commercial power supply 31 is cut off due to a power failure, the connection is interrupted at the contact 31a (solid line). The state in which the normal commercial power supply 31 can supply power is indicated by a dotted contact 31a. As will be described later, when the power supply is cut off, information is sent to the control unit 35 to switch from the normal entry / exit operation mode to the outage operation mode during a power failure either manually or automatically.

  In the parking device 10, the inverter 36 b converts the DC power from the converter 36 a into predetermined AC power and supplies the predetermined AC power to the drive motor 15. The inverter 36 c converts the DC power from the converter 36 a into predetermined AC power, and supplies the predetermined AC power to the traverse motor 23. A resistor 36e is connected to the inverter 36b. In the present embodiment, when the amount of power stored in the power storage device 32 reaches the normal upper limit value, the regenerative power from the drive motor 15 is consumed by the resistor 36e.

  The power storage device 32 is connected to the DC / DC converter 36d. The power storage device 32 is, for example, a lithium ion battery, a nickel metal hydride battery, a lead battery, a prismatic battery, an electric double layer capacitor, or the like, and is selected from those having a power storage function. The power storage device 32 receives the regenerative power generated from the drive motor 15 in the regenerative operation state via the DC / DC converter 36d and stores it. In the present embodiment, the power storage device 32 serves both as an energy saving application in the normal entry / exit operation and a power supply application in an emergency (power failure). Although not shown, an ammeter and a voltmeter are connected to the power storage device 32, the ammeter and the voltmeter detect the amount of power stored in the power storage device 32, and the information is sent to the control unit 35. In addition, the power storage device 32 can be connected to the external power source 33, and can be supplied with power from the external power source 33 to the power storage device 32. The external power source 33 is, for example, a generator, a solar power source, an electric vehicle, or the like.

  Furthermore, the control part 35 is connected to the DC / DC converter 36d as a control means of the parking apparatus 10. The control unit 35 controls a series of operations for entering and leaving the vehicle V in the parking device 10. The control unit 35 can receive power from both the commercial power supply 31 and the power storage device 32 via the DC / DC converter 36d. Further, the control unit 35 receives a signal from an operation unit (not shown) such as an operation panel that can be operated by the user. Then, the control unit 35 collects various information such as the power supply status from the commercial power supply 31, the position information of the lifting lift 12, the operating status of each motor, the maintenance information, the power storage amount of the power storage device 32, and the like. The operation of the parking device 10 is controlled so that the delivery operation is performed safely and reliably.

  Note that the power required to operate the control unit 35 and the traversing motor 23 is very small compared to the power required to drive the drive motor 15. Therefore, in order to operate the control unit 35 and the traversing motor 23, the power from the power storage device 32 can be sufficiently covered.

  Next, the control flow of the parking apparatus 10 in the loading / unloading operation of the vehicle V will be described based on a flowchart. The mechanical operation of the lifting lift 12 and the like is as described above.

  FIG. 4 is a flowchart for explaining the flow of control of the warehousing operation of the vehicle V in the normal warehousing / unloading operation mode in which the power supply from the commercial power supply 31 is not interrupted (in a daily power supply state). As shown in FIG. 4, the user inputs a warehousing instruction to the control unit 35 and starts the warehousing operation. In the normal warehousing / unloading operation mode, in the warehousing operation of the vehicle V, the drive motor 15 is driven by the power source 31 and the commercial power supply 31 and the power storage device so as to mainly drive the drive motor 15 to raise the lift 12 equipped with the vehicle V. Power is supplied from at least one of 32.

  First, immediately after the start of the warehousing operation, the control unit 35 determines whether or not the amount of power stored in the power storage device 32 is equal to or greater than the normal time lower limit value (step S01). The normal lower limit value is a value set in advance in the control unit 35 as the amount of power that allows the drive motor 15 to continue powering operation for a time (arbitrary) of several seconds to several tens of seconds. For example, if the electric power required to raise the lift 12 mounted with the vehicle V to the uppermost floor is about 30% of the maximum storage capacity of the power storage device 32, the lower limit value during normal operation is larger than 30% of the storage capacity 35. Set to ~ 40%. Such information can be collected in the control unit 35 and can be individually set for each floor of the parking room to be stored.

  In step S01, when the storage amount of the power storage device 32 is equal to or higher than the normal lower limit value, the drive motor 15, the traversing motor 22 and / or the control unit 35 are assisted to assist the commercial power source 31 or instead of the commercial power source 31. Electricity is supplied from the power storage device 32 and the warehousing operation is performed (step S02). The operation like step S02 using the power supply of the power storage device 32 is referred to as a power compensation operation. Even during the power compensation operation, the amount of power stored in the power storage device 32 is monitored to determine whether or not the amount of stored power reaches the normal time lower limit (step S03). When the power storage amount of the power storage device 32 does not reach the normal lower limit, the power compensation operation using the power from the power storage device 32 is continued, and the warehousing operation is completed. On the other hand, when the power storage amount of the power storage device 32 falls below the normal lower limit in the determination before the start of the power compensation operation (step S01) and the determination during the power compensation operation (step S03), the power supply from the power storage device 32 is cut off. Then, the commercial power supply operation is performed only with the electric power from the commercial power supply 31 (step S04), and the warehousing operation is completed.

  FIG. 5 is a flowchart for explaining the flow of control of the delivery operation of the vehicle V in the normal entry / exit operation mode in which the power supply from the commercial power supply 31 is not interrupted (in a normal power supply state). As shown in FIG. 5, the user inputs an exit instruction to the control unit 35 via the operation unit, and starts the exit operation. In the normal entry / exit operation mode, mainly in the delivery operation of the vehicle V, the drive motor 15 is regeneratively operated so as to lower the lift 12 mounted with the vehicle V. The control unit 35 and the traversing motor 23 receive power from the power storage device 32 and / or the commercial power supply 31.

  First, immediately after the start of the warehousing operation, the control unit 35 determines whether or not the amount of power stored in the power storage device 32 has reached the normal upper limit value (step S11). The normal upper limit value is a value (for example, a full charge amount value) preset in the control unit 35 as an upper limit value at which the power storage device 32 can no longer store power. The normal upper limit is set to 95 to 100% of the storage capacity, for example.

  In step S11, when the amount of electricity stored in the power storage device 32 has not reached the normal upper limit, the regenerative power from the drive motor 15 that performs the regenerative operation is stored in the power storage device 32 via the DC / DC converter 36d (step S11). S12). The operation like step S12 for storing the power storage device 32 is referred to as a regenerative power storage operation. Even during the regenerative power storage operation, the power storage amount of the power storage device 32 is monitored to determine whether or not the power storage amount reaches the normal upper limit value (step S13). When the power storage amount of the power storage device 32 does not reach the normal upper limit, the regenerative power storage operation is continued and the delivery operation is completed. On the other hand, if the amount of power stored in the power storage device 32 has reached the normal upper limit in the determination before the start of the regenerative power storage operation (step S11) and the determination during the regenerative power storage operation (step S13), in step S14, the drive motor 15 The regenerative electric power is consumed by a resistor (Examples 1 and 3), or power is returned to the commercial power supply 31 (Examples 2 and 4), and the delivery operation is completed.

  FIG. 6 is a flowchart for explaining the control flow of the delivery operation of the vehicle V in the delivery operation mode during a power failure when the power supply from the commercial power supply 31 is interrupted due to a power failure. When the control unit 35 detects that the power supply from the commercial power supply 31 has been cut off, the control unit 35 automatically or manually (for example, a user inputs to the operation panel) controls the operation of the parking device 10 during normal entry / exit operation. Switch from mode to power outage operation mode. At this time, control unit 35 receives power from power storage device 32 and maintains the operating state. As shown in FIG. 6, the user inputs an exit instruction to the control unit 35 and starts an emergency exit operation. In the unloading operation mode at the time of a power failure, mainly in the unloading operation of the vehicle V, the drive motor 15 is regeneratively operated so as to lower the lift 12 mounted with the vehicle V. Then, the control unit 35 and the traversing motor 23 receive power from the power storage device 32.

  First, immediately after the start of the warehousing operation, the control unit 35 determines whether or not the amount of power stored in the power storage device 32 is equal to or greater than the lower limit during power failure (step S21). When the amount of power stored in the power storage device 32 falls below the lower limit during power failure, the external power source 33 supplies power to the power storage device 32 and stores the power (step S22). The lower limit value at the time of a power failure is determined as the amount of electric power that can operate the elements other than the drive motor 15 such as the operation unit 35 and the traversing motor 23 to complete the delivery of at least one vehicle V. It is a set value. This lower limit during power failure is smaller than the lower limit during normal times. This is because the power consumption for operating the control unit 35 and the traversing motor 23 is much smaller than the power consumption for powering the drive motor 15. For example, if the power required to operate at least the control unit 35 and the traversing motor 23 is about 5% of the maximum power storage capacity of the power storage device 32 while leaving one vehicle V, the lower limit at power failure is set. What is necessary is just to set to 8-15% larger than 5% of electrical storage capacity.

  In step S22, when the amount of power stored in power storage device 32 is equal to or greater than the lower limit during power failure, control unit 35 determines that normal shipping operation is possible (without being uncontrollable) and performs shipping operation. . Subsequently, the lift lift 12 in the empty state is raised to the height of the predetermined parking chamber 20 (by the weight of the balance weight 18), and the regenerative power of the drive motor 15 is charged in the power storage device 32 (step S23 and FIG. a)). Electric power is supplied from the power storage device 32 to the traversing motor 23 that consumes a small amount of power, and the traversing tray 21 on which the vehicle V is mounted is traversed in the ascending / descending space 13 (see step S24 and FIG. 7A). Next, the vehicle V is transferred from the traversing tray 21 to the lift lift 12 (see step S25 and FIG. 7B), and the traversing tray 21 is traversed in the parking chamber 20. Subsequently, the lift lift 12 loaded with the vehicle V is lowered, and the regenerative power of the drive motor 15 is charged in the power storage device 32 (see step S26 and FIG. 7C). Thereby, the storage amount of the power storage device 32 is increased by the regenerative power more than before the delivery operation is performed (immediately before step S23), and the delivery of the vehicle V is completed (step S27). Next, the controller 35 determines whether or not the vehicle V remains in the other parking room 20 (step S28). If the vehicle V remains, the exit operation (step 21) is performed again without passing through steps 21 and 22. S23) is performed. By repeating these, even in the event of a power failure, the power storage device 32 and the regenerative power can be efficiently used, and all the vehicles V parked in the plurality of parking rooms 20 can be delivered.

  In the present embodiment, when the vehicle V is transferred from the traversing tray 21 to the lifting / lowering lift 12, the drive motor 15 is caused to perform a power running operation in order to move the lifting / lowering lift 12 above the traversing tray 21. However, since the distance of the power running operation of the drive motor 15 is very small (several centimeters to several tens of centimeters), the power of the power storage device 32 can be sufficiently covered.

  Hereinafter, the effect of the parking apparatus 10 of one Embodiment which concerns on this invention is demonstrated.

  In the parking device 10 of this embodiment, when the power supply from the commercial power supply 31 is cut off during a power failure, the operation of the control unit 35 is maintained by supplying power from the power storage device 32 to the control unit 35. Next, the control unit 35 raises the empty lift 12 to a predetermined position while causing the drive motor 15 to perform a regenerative operation. At this time, since the weight of the balance weight 18 is larger than the weight of the lifted lift 12 in the empty state, the balance weight 18 is lowered by its own weight, and the regenerative operation is performed without driving the drive motor 15, thereby reducing the amount of power stored in the power storage device 32. Can be increased. Then, by supplying relatively low power from the power storage device 32 to the transverse motor 23 (compared to the drive motor 15), the transverse motor 23 is controlled so as to horizontally move the transverse tray 21, and placed on the transverse tray 21. The parked vehicle V can be transferred to the lift lift 12. After the parked vehicle V is loaded on the lift lift 12 from the parking chamber 20, the control unit 35 controls the drive lift 15 to be lowered while the drive motor 15 is regeneratively operated. At this time, since the weight of the lift lift 12 in the loaded state is larger than the weight of the balance weight 18, the lift lift 12 is lowered by its own weight, and the regenerative operation is performed without causing the drive motor 15 to perform the power running operation, thereby reducing the amount of power stored in the power storage device 32. Can be increased. That is, in the shipping operation mode during a power failure, the control unit 35 and the traversing motor 23 are operated with relatively low power from the power storage device 32, and the traversing motor 23 is driven and the drive motor 15 is driven by a signal from the control unit 35. The parked vehicle V can be delivered by moving the lift 12 up and down while performing regenerative operation.

  Further, in the shipping operation mode at the time of power failure, it is determined whether or not the power storage amount of the power storage device 32 is equal to or greater than the lower limit value at the time of power failure (step S21). The power supply from the external power supply 33 to the power storage device 32 without starting the operation prevents the power supply from the power storage device 32 from being cut off during the first output operation and the control of the output operation. And if the amount of electrical storage of the electrical storage apparatus 32 is more than the lower limit at the time of a power failure, the mechanical operation | movement (step S23) of shipping operation will be started, and if the shipping operation of the 1st vehicle V is complete | finished, As a result, the power storage capacity of the power storage device 32 increases more than before the start of operation (step S23). Therefore, in this embodiment, even in the event of a power outage when there is no power supply from the commercial power supply 31, by efficiently using the power of the power storage device 32 and the regenerative power of the drive motor 15, a plurality of parking rooms 20 are provided. It is possible to let all parked vehicles V go out continuously.

FIG. 8 is a schematic configuration diagram of a parking apparatus according to another embodiment (Example 2). As shown in FIG. 8, in the parking apparatus of the second embodiment, a regenerative converter 36a ′ is arranged instead of the converter 36a and the resistor 36e is omitted as compared with the block diagram of FIG. That is, in Example 2, when the amount of electricity stored in the power storage device 32 is equal to or greater than the upper limit value, the regenerative power from the motor 15 is supplied to the commercial power supply 31 via the regenerative converter 36a ′ without consuming the regenerative power by the resistor. The power is returned (step S14).

(Example 3)
FIG. 9: is a schematic block diagram of the parking apparatus of another embodiment (Example 3). As shown in FIG. 9, the power storage device 32 ′ of the parking device according to the third embodiment is not divided into one (for emergency and energy saving) power storage device 32 as compared with the block diagram of FIG. The first power storage device 32a for energy saving and the second power storage device 32b for emergency (power failure) are provided. The first power storage device 32a and the second power storage device 32b are connected to the DC / DC converter 36d via the first switch 32c and the second switch 32d, respectively. That is, the 1st electrical storage apparatus 32a is comprised for the energy saving in normal time storage / extraction operation. On the other hand, the 2nd electrical storage apparatus 32b is comprised for the electric power feeding at the time of a power failure. These first and second power storage devices 32a and 32b are connected to an external power source 33 such as a generator, a solar power source, and an electric vehicle, and can receive power simultaneously or individually.

  In the third embodiment, in the normal entry / exit operation mode, the control unit 35 controls the first switch 32c to be turned on and the second switch 32d to be turned off. Only the first power storage device 32a is connected to the DC / DC converter 36d. On the other hand, in the shipping operation mode during a power failure, the control unit 35 controls the first switch 32c to be turned off and the second switch 32d to be turned on. Only the second power storage device 32b is connected to the DC / DC converter 36d. In other words, by separating the power storage device 32 into the first power storage device 32a and the second power storage device 32b, in the normal normal loading / unloading operation, priority is given to the use of the first power storage device 32a for energy saving. The second power storage device 32b can be preserved. In this manner, the performance of the second power storage device 32b is prevented from deteriorating due to daily use, and the risk of failure is reduced, and the power supply function is more reliably exhibited in the emergency operation mode for power outages during an emergency. Enable. Therefore, the parking apparatus of a present Example improves the reliability of the parking operation of the parking apparatus in the shipping operation at the time of a power failure.

As shown in FIG. 10, in the parking device of the fourth embodiment, a regenerative converter 36a ′ is arranged instead of the converter 36a, and the resistor 36e is omitted as compared with the block diagram of FIG. That is, in Example 4, when the amount of electricity stored in the power storage device 32 is equal to or greater than the upper limit value, the regenerative power from the motor 15 is supplied to the commercial power supply 31 via the regenerative converter 36a ′ without consuming the regenerative power by the resistor. The power is returned (step S14).

With reference to Fig.11 (a)-(c), the process of unloading a vehicle in the unloading operation mode at the time of a power failure with pallet type multistory parking apparatus 10 'is demonstrated. In the pallet type multilevel parking apparatus 10 ′, the weight of the balance weight 18 ′ is larger than the total weight of the pallet P and the lift lift 12 ′ and smaller than the total weight of the pallet P, the lift lift 12 ′ and the vehicle V.

  As shown in FIG. 11 (a), the lifting lift 12 ′ carrying the empty pallet P is raised to a predetermined parking room 20 ′ by regenerative operation, and the empty pallet P is moved to the empty parking room 20 ′. return. Next, the vehicle V is raised to the parking room 20 'of the vehicle V to be delivered by regenerative operation. Then, as shown in FIG. 11 (b), the pallet P on which the parked vehicle V is mounted is moved laterally into the lift space 13 'and loaded on the lift lift 12'.
