The power feeding efficiency of each power feeding coil 21a may be estimated from the distance from the power receiving coil 2a. That is, it may be estimated that the power feeding coil 21a, which is closer to the power receiving coil 2a, has better power feeding efficiency. In this case, the determination unit 24 selects one or a plurality of power feeding coils 21a having the closest distance from the power receiving coil 2a.
The determination unit 24 transmits the determined information to the power supply coil control device 25.

The image processing device 28, the communication control device 30, the parking facility control device 34, and the determination unit 24 are, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and a computer-readable storage. It is composed of media and the like. As an example, a series of processes for realizing various functions are stored in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is installed in a ROM or other storage medium in advance, is provided in a state of being stored in a computer-readable storage medium, or is distributed via a wired or wireless communication means. Etc. may be applied. Computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, semiconductor memories, and the like.

The power supply coil control device 25 is configured to be able to switch between supply and non-supply of electric power from the power supply 22 to each power supply coil 21a. Further, the power feeding coil control device 25 switches between supply and non-supply of electric power to each power feeding coil 21a so that power is supplied only from the power feeding coil 21a determined by the determination unit 24. That is, power is supplied only to the power feeding coil 21a determined by the determination unit 24, and power is not supplied to the other power feeding coils 21a.

Next, the process performed when the parking facility 1 determines the power feeding coil 21a to supply power will be described with reference to the flowchart of FIG.
First, in S1, the specific unit 23 acquires the imaging data captured by the camera 27, the vehicle information received by the antenna 29, the change in the magnetic field of the power feeding coil 21a detected by the detection unit, and the authentication information input to the numeric keypad 31 and the like. To do. Next, based on various data acquired in S2, the specific unit 23 (specifically, the image processing device 28, the communication control device 30 and the parking facility control device 34) is the power receiving coil 2a provided in the vehicle 2. Identify the location. Next, in S3, the determination unit 24 receives the position of the power receiving coil 2a specified by each device from the image processing device 28, the communication control device 30, and the parking facility control device 34, and moves to the position of the received power receiving coil 2a. Based on this, the feeding coil 21a for feeding is determined from the plurality of feeding coils 21a. When the power feeding coil 21a to supply power is determined, this process ends. In this way, the parking facility 1 determines the power feeding coil 21a that supplies power.

Next, the operation method of the parking facility 1 will be described. Hereinafter, an example of storing the vehicle 2 adopting the non-contact power supply system will be described.
When the vehicle 2 is stored in the parking facility 1, first, a process of determining the power supply coil 21a for supplying the above-mentioned power supply to the vehicle 2 that has entered the boarding / alighting room 3 is performed. Next, the entry / exit door is opened, and the vehicle 2 is mounted on the pallet 15 lowered to the entry floor. When the vehicle 2 is mounted on the pallet 15, the pallet 15 ascends the hoistway 13 by the conveyor 7. The carrier 7 stops when it rises to a height adjacent to the storage shelf 14 in which the vehicle 2 is stored. When the carrier 7 is stopped, the pallet 15 is transferred toward the storage shelf 14 by the transfer device, and the pallet 15 is stored in the storage shelf 14. When the pallet 15 is stored in the storage shelf 14, each power feeding coil 21a provided on the pallet 15 is connected to the power supply 22, and power can be supplied to each power feeding coil 21a. When each power feeding coil 21a is connected to the power supply 22, power is supplied only to the power feeding coil 21a determined by the determination unit 24 by the power feeding coil control device 25.

According to this embodiment, the following actions and effects are exhibited.
In the present embodiment, the power feeding unit 21 is provided on the pallet 15 mounted when the vehicle 2 is stored. As a result, when the vehicle 2 adopting the non-contact power feeding method (for example, an electric vehicle or the like) is stored, power can be supplied from the power feeding unit 21 to the stored vehicle 2.

When power is supplied to the vehicle 2 that employs the non-contact power supply method, the position is such that the power supply unit 21 (specifically, the power supply coil 21a) and the power receiving coil 2a provided in the vehicle 2 are in a position where power can be supplied. It is necessary to make adjustments. On the other hand, the position of the power receiving coil 2a provided in the vehicle 2 adopting the non-contact power feeding method differs depending on the manufacturer of the vehicle 2, the vehicle type, and the like.
In the present embodiment, the pallet 15 is provided with a power feeding unit 21 having a plurality of power feeding coils 21a arranged along the front-rear direction of the vehicle 2. As a result, power can be supplied by aligning either of the power feeding coils 21a and the power receiving coil 2a, so that it is possible to easily align the power feeding coil 21a and the power receiving coil 2a in the front-rear direction. Therefore, when the user mounts the vehicle 2 on the pallet 15 and aligns the power feeding coil 21a and the power receiving coil 2a, the alignment can be facilitated. Therefore, the convenience of the user can be improved. In particular, in the present embodiment, since the feeding coil 21a is provided in substantially the entire longitudinal direction of the pallet 15, it is not necessary for the user to perform the alignment, so that the convenience of the user can be further improved.

As a method of aligning the power feeding coil 21a and the power receiving coil 2a, a method of moving the power feeding coil to enable power feeding is also conceivable. However, such a method requires an actuator or the like, which complicates the structure. Further, a method of moving the vehicle 2 to enable power supply is conceivable, but similarly, there is a problem that an actuator or the like is required and the structure is complicated, and the maximum size vehicle that can be accommodated in the storage space of the vehicle 2 is also conceivable. There is also a problem that the vehicle 2 cannot be moved when the vehicle 2 is stored.

On the other hand, in the present embodiment, since the plurality of feeding coils 21a are only arranged side by side, no actuator or the like is provided. As a result, the configuration can be simplified as compared with the configuration in which the actuator or the like is provided. Therefore, the initial cost when manufacturing the parking facility 1 can be reduced. Moreover, since the configuration is simple, the frequency of failures can be reduced. Therefore, the reliability can be improved, and the configuration can be configured with less repairs, so that the running cost can be reduced. Further, since the actuator or the like is not provided, the consumables constituting the actuator or the like can be eliminated. Therefore, the repair frequency can be further suppressed.

Further, in the present embodiment, the position of the power receiving coil 2a provided in the vehicle 2 is specified by the specific unit 23, and the power feeding coil 21a for supplying power is determined based on the specified position of the power receiving coil 2a. With this configuration, even if the power receiving coil 2a is provided in the front part of the vehicle 2 as shown in FIG. 5A, the power receiving coil 2a is provided in the rear part of the vehicle 2 as shown in FIG. 5B. Even if this is the case, power is supplied by the power feeding coil 21a provided in the vicinity of the power receiving coil 2a (in the example shown in FIGS. 5A and 5B, the power feeding coil 21a provided vertically below the power receiving coil 2a). Can be done. Further, when the number of the power feeding coils 21a for supplying power is two, as shown in FIG. 5C, the power can be supplied by the two feeding coils 21a in the vicinity of the power receiving coil 2a.

As a result, the power supply coil 21a that does not supply power can be configured so that power is not supplied. Therefore, since extra power is not supplied, deterioration of power supply efficiency can be suppressed. Further, since power is not supplied to the power feeding coil 21a that does not supply power, the leakage magnetic field can be suppressed. Therefore, safety can be improved.
Further, the determination unit 24 determines the power supply coil 21a to supply power from among the plurality of power supply coils 21a so that the power supply efficiency is high. That is, the determination unit 24 selects the power supply coil 21a that can supply power most efficiently. Therefore, the power feeding efficiency of the power feeding unit 21 can be improved.

Further, in the present embodiment, the position of the power receiving coil 2a provided on the vehicle 2 is based on the correspondence between the authentication information input by the user on the numeric keypad 31 or the like and the authentication information stored in the storage unit and the vehicle information. Is specified. Thereby, the vehicle information can be specified from the authentication information based on the correspondence relationship, and the position of the power receiving unit can be specified based on the specified vehicle information. Therefore, the position of the power receiving unit can be specified more accurately. In particular, it is effective when the parking facility 1 is an environment mainly used by a specific user.

Further, in the present embodiment, the antenna 29 receives the vehicle information from the vehicle 2, and the position of the power receiving coil 2a provided in the vehicle 2 is specified based on the received vehicle information. As a result, vehicle information can be acquired from the target vehicle 2 for specifying the position of the power receiving coil 2a, and the position of the power receiving coil 2a can be specified based on the vehicle information. Therefore, the position of the power receiving coil 2a can be specified more accurately.

Further, in the present embodiment, a detection unit for detecting a change in the magnetic field of the power feeding coil 21a is provided, and the position of the power receiving unit provided in the vehicle 2 is specified based on the information from the detection unit. With this configuration, the position of the power receiving coil 2a in the state where the vehicle 2 is actually mounted on the pallet 15 can be specified. Therefore, the determination unit 24 can more accurately select the feeding coil 21a in which the feeding efficiency is high. Therefore, the power feeding efficiency of the power feeding unit 21 can be further improved.

Further, by specifying the position of the power receiving coil 2a by the power feeding coil 21a for supplying power, it is not necessary to provide a dedicated device for specifying the position of the power receiving coil 2a. Therefore, the number of parts can be reduced and the configuration can be simplified.

Further, in the present embodiment, the camera 27 for photographing the vehicle 2 is provided, and the position of the power receiving coil 2a provided on the vehicle 2 is specified based on the imaged data. Thereby, the position of the power receiving coil 2a can be specified more accurately.

[Modification 1]
Next, a modified example (modified example 1) of the present embodiment will be described with reference to FIGS. 6 to 7C. In the parking facility 1 according to the present modification, the power feeding unit provided on the pallet 15 is different from that of the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIGS. 6 and 7, the power feeding unit 41 according to this modification is a plurality of power feeding coils 21a (hereinafter, described later, upper part) arranged side by side at predetermined intervals along the longitudinal direction of the pallet 15. In order to distinguish it from the feeding coil 41b, it has a "lower feeding coil 41a") and an upper feeding coil 41b provided so as to bridge the adjacent lower feeding coils 41a. The lower surface of the upper feeding coil 41b is in contact with the upper surface of the lower feeding coil 41a. That is, the lower feeding coil 41a and the upper feeding coil 41b are provided so as to overlap each other, and are arranged so as to be offset in the longitudinal direction of the pallet 15.

Further, each upper feeding coil 41b is provided so that the height position of the upper surface (upper end) is substantially the same as the upper surface of the central convex portion 15a of the pallet 15. The mode in which each upper feeding coil 41b is provided is not limited to this. Each upper feeding coil 41b may be provided so that the distance B (see FIG. 7A) between the upper end of the upper feeding coil 41b and the upper surface of the wheel guide groove 15c is smaller than a predetermined value. For example, each upper feeding coil 41b may be provided so that the upper surface (upper end) is lower than the upper surface of the central convex portion 15a of the pallet 15, and the upper surface (upper end) is the central convex portion of the pallet 15. It may be provided so as to be above the upper surface of 15a. The predetermined value is determined based on, for example, the minimum ground height of the vehicle 2 that can be stored in the parking facility 1.

Further, in FIG. 7A, the height position of the lower surface (lower end) of the lower feeding coil 41a is provided so as to be substantially the same as the height position of the upper surface of the wheel guide groove 15c of the pallet 15. , The present invention is not limited to this. For example, the lower feed coil 41a may be provided so that the lower surface (lower end) is below the upper surface of the wheel guide groove 15c of the pallet 15, and the lower surface (lower end) is the wheel guide groove 15c of the pallet 15. It may be provided so as to be above the upper surface of the wheel.

According to this modification, the following effects are exhibited.
According to this modification, the feeding coil (lower feeding coil 41a and upper feeding coil 41b) can be provided on the pallet 15 without a gap. Therefore, it is possible to more accurately supply power with the power feeding coil corresponding to the power receiving coil 2a. Therefore, the power feeding efficiency can be further improved.

The feeding coil 42a may be provided as in the feeding portion 42 shown in FIG. 7B. In the feeding portion 42 shown in FIG. 7B, one end of the flat plate-shaped feeding coil 42a is provided so as to overlap the other end of the feeding coil adjacent to one end side from above. That is, the feeding coil 42a is arranged so as to be inclined with respect to the horizontal plane. Further, each feeding coil 42a is provided so that the distance C between the upper end of the feeding coil 42a and the upper surface of the wheel guide groove 15c is smaller than a predetermined value.
Even if a plurality of feeding coils 42a are arranged side by side in this way, the feeding coils 42a can be provided on the pallet 15 without any gaps. Therefore, power can be supplied more accurately by the power feeding coil 42a corresponding to the power receiving coil 2a, and the power feeding efficiency can be further improved.

Further, a power feeding coil 43a may be provided as in the power feeding unit 43 shown in FIG. 7C. Each power feeding coil 43a has a stepped portion formed in the central region, and one end portion is located above the other end portion. Further, one end of the feeding coil 43a is provided so as to overlap the other end of the feeding coil adjacent to the one end side from above. Further, each feeding coil 43a is provided so that the distance D between the upper end of the feeding coil 43a and the upper surface of the wheel guide groove 15c is smaller than a predetermined value.
Even if a plurality of power feeding coils 43a are arranged in this way, the power feeding coils 43a can be provided on the pallet 15 without any gaps. Therefore, power can be supplied more accurately by the power feeding coil 43a corresponding to the power receiving coil 2a, and the power feeding efficiency can be further improved.

[Modification 2]
Next, a modified example (modified example 2) of the present embodiment will be described with reference to FIGS. 8 and 9. In the parking facility 1 according to the present modification, the power feeding unit provided on the pallet 15 is different from that of the first embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
As shown in FIG. 8, the feeding portion 46 according to this modification is provided only from the central region in the longitudinal direction of the pallet 15 to one end in the longitudinal direction. That is, in this modification, the feeding portion 46 (feeding coil 46a) is provided from one end of the pallet 15 to a portion slightly beyond the center point C1.
In addition, this modification and the above-mentioned modification 1 may be combined. That is, the feeding coils may be provided so as to overlap only from the central region in the longitudinal direction of the pallet 15 to one end in the longitudinal direction.

Next, the process performed when the parking facility according to this modified example stores the vehicle 2 will be described with reference to the flowchart of FIG.
First, when there is a warehousing request for the vehicle 2, the parking facility performs S4. In S4, the position of the power receiving coil 2a provided in the vehicle 2 is specified. Since the method of specifying the position of the power receiving coil 2a is the same as that of the first embodiment, detailed description thereof will be omitted. At the same time, the feeding coil 21a for feeding power is determined. Since the method of determining the power feeding coil 21a to supply power is the same as that of the first embodiment, detailed description thereof will be omitted.

Next, the process proceeds to S5, and it is determined whether or not the position of the power receiving coil 2a matches the position of the feeding coil 21a provided on the pallet 15. Specifically, it is estimated from the position of the power receiving coil 2a whether the power receiving coil 2a is located on one end side or the other end side of the center point C1 when the vehicle 2 is mounted on the pallet 15. Then, when it is estimated that the power receiving coil 2a is located on one end side of the center point C1, it is determined that the position of the power receiving coil 2a matches the position of the power feeding coil 21a. On the other hand, when it is estimated that the power receiving coil 2a is located on the other end side of the center point C1, it is determined that the position of the power receiving coil 2a does not match the position of the power feeding coil 21a.

If it is determined in S5 that the position of the power receiving coil 2a matches the position of the power feeding coil 21a, the process proceeds to S6 and the entry / exit door is opened. Next, in S7, the vehicle 2 is mounted on the pallet 15 lowered to the boarding floor, and it is confirmed that the periphery of the pallet 15 is unmanned. Next, proceed to S8 and close the entry / exit door. Next, in S9, the pallet 15 on which the vehicle 2 is mounted is conveyed to the storage shelf 14 by the transfer machine 7, and the pallet 15 is stored in the storage shelf 14. When the pallet 15 is stored in the storage shelf 14, each power feeding coil 21a provided on the pallet 15 is connected to the power supply 22, and power can be supplied to each power feeding coil 21a. Next, in S10, the power supply coil control device 25 supplies power only to the power supply coil 21a determined by the determination unit 24. When the electric power is supplied, the process of storing the vehicle 2 ends.

If it is determined in S5 that the position of the power receiving coil 2a does not match the position of the feeding coil 21a, the process proceeds to S11. In S11, the swivel device 4 swivels the pallet 15 180 degrees around the center point C1. When the pallet 15 is turned, the process proceeds to S6. Subsequent processing is the same as in S5 when it is determined that the position of the power receiving coil 2a matches the position of the feeding coil 21a, and thus the description thereof will be omitted.

According to this modification, the following effects are exhibited.
In this modification, the feeding portion 46 is provided only from the central region in the longitudinal direction of the pallet 15 to one end in the longitudinal direction. When the power receiving coil 2a of the vehicle 2 mounted on the pallet 15 is in a position where power can be supplied from the power feeding unit 46 (that is, when the position of the power receiving coil 2a matches the position of the power feeding coil 21a), the power is conveyed as it is. The pallet 15 is conveyed to the storage shelf 14 by the machine 7. On the other hand, when the power receiving coil 2a of the vehicle 2 mounted on the pallet 15 is not in a position where power can be supplied from the power feeding unit 46 (that is, when it is determined that the position of the power receiving coil 2a does not match the position of the power feeding coil 21a). By turning the pallet 15 180 degrees by the turning device 4 before the vehicle 2 is mounted, the power feeding coil 21a and the power receiving coil 2a can be set to a position where power can be supplied.

As described above, even in a configuration in which the power feeding portion 46 is not provided in substantially the entire longitudinal direction of the pallet 15, the power receiving coil 2a and the power feeding coil 21a can be reliably set to a position where power can be supplied. Therefore, the number of feeding coils 21a can be reduced as compared with the configuration in which the feeding portion is provided from one end to the other end in the longitudinal direction. Therefore, the initial cost can be reduced. Further, since the number of the feeding coils 21a can be reduced and the configuration can be simplified, the failure frequency can be reduced and the running cost can be reduced.

[Second Embodiment]
Next, the second embodiment of the present invention will be described with reference to FIGS. 10 to 13C. The parking facility 51 according to the present embodiment is different from the first embodiment in that the feeding portion is mainly provided on the storage shelf instead of the pallet. In the following description, the same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In FIG. 10, for the sake of illustration, the opening pit 3b and the swivel device 4 are omitted.

As shown in FIG. 10, the parking facility 51 includes a plurality of storage shelves 54 provided on both sides of the hoistway 13, and a plurality of pallets 55 stored in each storage shelf 54.
As shown in FIG. 11A, each storage shelf 54 has two roller frames 56 protruding from the side wall of the parking facility 51 toward the inside of the parking facility 51 (that is, the hoistway 13 direction), and below the roller frame 56. The two feeding coil abutments 62 projecting from the side wall of the parking facility 51 toward the inside of the parking facility 51 and the substantially centers of the two feeding coil abutments 62 in the extending direction are provided so as to bridge each other. It has a connection portion 57.

The two roller frames 56 have substantially the same length and are provided substantially in parallel. Further, each roller frame 56 has a base portion 56a which is frame-shaped and one end of which is fixed to the side wall of the parking facility 51, and a plurality of roller portions 56b whose upper ends project from the upper surface of the base portion 56a. By placing the pallet 55 on the two roller frames 56, the pallet 55 is stored in the storage shelf 54. Further, when the pallet 55 is stored, the pallet 55 is placed on the roller portion 56b, and the pallet 55 is moved by the rotation of the roller portion 56b.
The two feeding coil abutments 62 have substantially the same length and are provided substantially in parallel. Each feeding coil abutment is a frame-shaped member and is formed shorter than the roller frame 56. Further, each feeding coil abutment 62 is provided so as to be located between the two roller frames 56 when viewed from above.

The connecting portion 57 includes a main body portion 58 provided with the feeding portion 61, and a supporting portion 59 (see FIG. 13A) that supports the main body portion 58 on the feeding coil abutment 62.
The main body 58 is a plate-shaped member extending in a direction orthogonal to the feeding coil abutment 62. The main body portion 58 is located above the upper end of the roller portion 56b of the roller frame 56. The main body 58 is located below the central convex portion 15a of the pallet 55 when the pallet 55 is stored in the storage shelf 54. The length of the main body 58 in the longitudinal direction (extending direction) is set shorter than the length of the pallet 55 in the longitudinal direction. Further, the length of the main body 58 in the lateral direction is set to be slightly shorter than the length of the central convex portion 15a of the pallet 55 in the width direction. On the upper surface of the main body 58, a power feeding unit 61 constituting the power feeding device 60 is provided. Specifically, a plurality of feeding coils 21a are arranged side by side at predetermined intervals along the longitudinal direction. The power feeding portion 61 is provided over substantially the entire longitudinal direction of the main body portion 58.

As shown in FIG. 13A, the support portion 59 has a spring portion (biased portion) 59a provided on the upper surface of the power feeding coil abutment 62, and a tubular portion 59b that covers the spring portion 59a. The support portion 59 supports the main body portion 58 so that the height position of the main body portion 58 is substantially the same as the height position of the upper end of the pallet 55 in the state of being stored in the storage shelf 54. The support portion 59 may support the main body portion 58 so that the height position of the main body portion 58 is higher than the height position of the upper end of the pallet 55 in the state of being stored in the storage shelf 54.

The spring portion 59a supports the main body portion 58 from below and urges the main body portion 58 upward. Specifically, the lower end of the spring portion 59a is fixed to the upper surface of the feeding coil abutment 62, and the upper end of the spring portion 59a is fixed to the lower surface of the main body portion 58. Further, two spring portions 59a are provided on each feeding coil abutment 62. That is, the main body portion 58 is supported by four spring portions 59a. The two spring portions 59a provided on one feeding coil abutment 62 are arranged at a predetermined distance in the extending direction of the feeding coil abutment 62, and the end portions of the main body portion 58 in the lateral direction are respectively arranged from below. I support it.

The tubular portion 59b is a cylindrical member whose central axis extends in the vertical direction. The tubular portion 59b accommodates the spring portion 59a in the space formed inside. The upper end of the tubular portion 59b is fixed to the lower surface of the main body portion 58. The vertical length of the tubular portion 59b is set shorter than the vertical length of the spring portion 59a in a normal state (a state in which no external force is applied). With this configuration, the lower end of the tubular portion 59b comes into contact with the upper surface of the feeding coil abutment 62 when the spring portion 59a contracts to a predetermined length, so that the spring portion 59a does not contract any further.

As shown in FIG. 12A, the pallet 55 is different from the pallet 15 described in the first embodiment in that the feeding portion 21 is not provided on the central convex portion 15a and an opening 55a is formed instead. There is. The same points as those of the pallet 15 described in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
The central convex portion 15a of the pallet 55 is formed with an opening (passing portion) 55a that communicates the upper surface and the lower surface of the central convex portion 15a in substantially the entire area in the longitudinal direction and the width direction. The opening 55a is located above the main body 58 when the pallet 55 is stored in the storage shelf 54. That is, the opening 55a is formed at a position corresponding to the feeding portion 61. By forming the opening 55a in this way, the magnetic field from the feeding portion 61 provided in the main body 58 passes through the opening 55a, so that the pallet 55 can be prevented from blocking the magnetic field. By passing a magnetic field, it is possible to supply power to the power receiving coil 2a of the vehicle 2 mounted on the pallet 55 from the power feeding unit 61. Instead of the opening 55a, substantially the entire area of the central convex portion 15a may be formed of a non-magnetic material. Further, the entire pallet 55 may be formed of a non-magnetic material. Even with this configuration, the magnetic field from the feeding unit 61 can be passed through without being cut off.

In this embodiment, the connection portion 57 is provided only in a part of the plurality of storage shelves 54. Specifically, the storage shelves 54 from the lower part to the second stage are provided with a connection portion 57 to provide a non-contact power supply storage shelf 54. With such a configuration, the cost can be reduced as compared with the configuration in which all the storage shelves 54 can be contactlessly fed. The vehicle 2 for which power supply has been completed may be configured to be moved together with the pallet 55 to a normal storage shelf 54 (storage shelf 54 for which non-contact power supply cannot be performed). With this configuration, even if only a part of the vehicle can be non-contactly fed, it is possible to supply more non-contact power to the vehicle 2.

In this embodiment, the following effects are exhibited.
In the present embodiment, the power feeding unit 61 is provided on the storage shelf 54 for storing the vehicle 2. Further, the pallet 55 is formed with an opening 55a at a position corresponding to the feeding portion 61. As a result, in a state where the pallet 55 on which the vehicle 2 is mounted is stored in the storage shelf 54, power can be supplied from the power feeding unit 61 to the power receiving coil 2a without being hindered by the pallet 55. Further, as in the first embodiment, the alignment can be facilitated, the convenience of the user can be improved, and the configuration can be simplified.

Further, in the present embodiment, the pallet 55 is formed by bending one steel plate. Therefore, unevenness is formed on the lower surface of the pallet 55. That is, the central convex portion 15a protruding upward is a concave portion recessed upward on the lower surface of the pallet 55.
By the way, when the pallet 55 is transferred from the transport machine 7 to the storage shelf 54, the pallet 55 is moved in the horizontal direction as shown in FIGS. 13A to 13C. At this time, it is necessary to prevent the connecting portion 57 from hindering the transfer. In order not to interfere with the transfer, for example, as shown in FIG. 18, the upper end of the connecting portion 57'should be lower than the lower end of the pallet 55 (that is, the upper end of the roller portion 56b of the roller frame 56). Can be considered. However, when the upper end of the connecting portion 57'is lower than the lower end of the pallet 55, the distance L2 from the feeding portion 61' to the power receiving coil 2a becomes long. In non-contact power feeding, the distance between the power feeding coil and the power receiving coil 2a greatly affects the power feeding efficiency. Therefore, in the configuration shown in FIG. 18, the power feeding efficiency may decrease.

On the other hand, in the present embodiment, the spring portion 59a urges the main body portion 58 provided with the feeding coil 61a in the direction of the vehicle 2. As a result, when a portion such as the wheel guide groove 15c in which the lower surface of the pallet 55 projects downward passes, the spring portion 59a contracts due to the pressing force of the pallet 55, and the height of the connecting portion 57 is lowered. (See FIG. 13B). As a result, the connecting portion 57 can be prevented from hindering the transfer of the pallet 55. Further, after the portion where the lower surface of the pallet 55 projects downward has passed, the main body portion 58 moves upward by the urging force of the spring portion 59a (see FIG. 13C). As a result, the distance between the power feeding unit 61 and the power receiving coil 2a provided in the vehicle 2 can be shortened. Therefore, the power feeding efficiency can be improved.

Further, since it is composed only of the spring portion 59a without providing an actuator or the like, the configuration can be simplified. Therefore, the configuration can be configured with a low failure frequency, the reliability can be improved, and the running cost can be reduced.

In the present embodiment, an example in which the power feeding portion 61 is formed in substantially the entire longitudinal direction of the main body 58 has been described, but as shown in FIG. 11B, the main body 58 is formed from the central region of the main body 58 in the longitudinal direction. The feeding portion 61 may be provided only up to one end in the longitudinal direction of the above. That is, the feeding portion 41 (feeding coil 61a) is provided from one end of the main body portion 58 to a portion slightly beyond the center point C2.

When the power feeding unit 61 is provided only from the central region in the longitudinal direction of the main body 58 to one end in the longitudinal direction of the main body 58, the vehicle 2 is stored as follows. When the power receiving coil 2a of the vehicle 2 mounted on the pallet 55 is in a position where power can be supplied from the power feeding unit 61, the pallet 55 is directly conveyed to the storage shelf 54 by the conveyor 7. On the other hand, when the power receiving coil 2a of the vehicle 2 mounted on the pallet 55 is not in a position where power can be supplied from the power feeding unit 61, the pallet 55 is swiveled by the swivel device 4 with the vehicle 2 mounted. The power feeding coil 61a and the power receiving coil 2a can be positioned so that power can be supplied.

As described above, even in a configuration in which the power feeding portion 61 is not provided in substantially the entire longitudinal direction of the main body portion 58, the power receiving coil 2a and the power feeding coil 61a can be reliably set to a position where power can be supplied. Therefore, the number of feeding coils 61a can be reduced as compared with the configuration in which the feeding coils 61a are provided from one end to the other end in the longitudinal direction. Therefore, the initial cost can be reduced. Further, since the number of feeding coils 61a can be reduced and the configuration can be simplified, the failure frequency can be reduced and the running cost can be reduced.

When the feeding portion 61 is provided only from the central region in the longitudinal direction of the main body portion 58 to one end in the longitudinal direction of the main body portion 58, as shown in FIG. 12B, from the central region in the longitudinal direction of the central convex portion 15a. The opening 55b may be formed only up to one end in the longitudinal direction of the central convex portion 15a. That is, the opening 55b may be formed from one end of the central convex portion 15a to a portion slightly beyond the center point C3. With this configuration, the area of the opening 55b can be reduced, so that a decrease in the rigidity of the pallet 55 can be suppressed. In the case of this configuration, when the vehicle 2 is mounted on the pallet 55, the vehicle 2 is mounted on the pallet 55 after the position of the power receiving coil 2a of the vehicle 2 and the position of the opening 55b are made to correspond to each other. .. That is, when the position of the power receiving coil 2a and the position of the opening 55b do not correspond to each other, the pallet 55 is turned 180 degrees before the vehicle 2 is mounted.

It has a second flange portion 64b and a bolt 64c that engages with the second flange portion 64b. The second flange portion 64b is formed with a bolt hole (not shown) penetrating in the vertical direction and is located above the first flange portion 64a. A bolt 64c is inserted into the bolt hole from above and screwed into the bolt hole. The lower end of the bolt 64c protrudes from the lower surface of the second flange portion 64b. Further, the lower end of the bolt 64c is in contact with the upper surface of the first flange portion 64a.

According to this modification, the protruding amount E of the main body 58 can be adjusted by adjusting the protruding amount of the bolt 64c protruding from the lower surface of the second flange portion 64b, so that the power receiving coil 2a and the feeding coil 61a can be adjusted. The distance from and can be a desired distance. Therefore, the power feeding efficiency can be further improved.

[Modification example 4]
Next, a modified example (modified example 4) of the present embodiment will be described with reference to FIG. In FIG. 15, the roller frame 56 is omitted for the sake of illustration. The parking facility 1 according to the present modification is different from the second embodiment in that guide portions 65 are provided on both side surfaces of the main body portion 58 in the lateral direction. The same components as those in the second embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
The guide portion 65 has an inclined surface 65a extending downward from the upper surface of the main body portion 58 and in a direction away from the main body portion 58. Further, the guide portion 65 is provided in substantially the entire longitudinal direction of the main body portion 58. The guide portion 65 may be provided in a part of the main body portion 58 in the longitudinal direction. For example, the guide portions 65 may be provided only at both ends in the longitudinal direction.

In this modification, when the pallet 55 is transferred from the transporter 7 to the storage shelf 54, when the connecting portion 57 (specifically, the inclined surface 65a of the guide portion 65) and the pallet 55 come into contact with each other, the pallet 55 comes into contact with the inclined surface 65a. Press. Since the inclined surface 65a extends downward from the upper surface of the main body 58 and in a direction away from the main body 58, the pressing force of the pallet 55 pushes the connecting portion 57 downward with respect to the connecting portion 57. It acts to guide you. From the above, it is possible to easily move the connecting portion 57 downward. Therefore, it is possible to more reliably prevent the connecting portion 57 from hindering the transfer of the pallet 55.

[Modification 5]
Next, a modified example (modified example 5) of this embodiment will be described with reference to FIGS. 16A and 16B. In FIG. 16A, the roller frame 56 is omitted for the sake of illustration. The parking facility 1 according to the present modification is different from the second embodiment in that guide rollers 66 are provided on both side surfaces of the main body 58 in the lateral direction. The same components as those in the second embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
The guide roller 66 is a roller member that rotates about a central axis extending along the longitudinal direction of the main body 58, and is rotatably supported by the main body 58. Further, as shown in FIG. 16B, the guide rollers 66 are provided only at both ends of the main body 58 in the longitudinal direction. The guide roller 66 may be provided in substantially the entire longitudinal direction of the main body 58.

In this modification, when the pallet 55 is transferred from the transporter 7 to the storage shelf 54, when the connecting portion 57 and the pallet 55 (specifically, the guide roller 66) come into contact with each other, the pallet 55 presses the guide roller 66. The guide roller 66 is rotatably supported around a central axis extending along the longitudinal direction of the main body 58. Therefore, the guide roller 66 is pressed against the pallet 55 to rotate. When the guide roller 66 is pressed against the pallet 55, the pressing force of the pallet 55 acts to guide the connecting portion 57 downward with respect to the connecting portion 57. From the above, it is possible to easily move the connecting portion 57 downward. Therefore, it is possible to more reliably prevent the connecting portion 57 from hindering the transfer of the pallet 55.
