The charging pallet 20 has the same form as the standard pallet 90. In this example, the standard pallet 90 and the charging pallet 20 are mixedly mounted, but all may be configured by the charging pallet 20.

  On the other hand, the elevator shaft 10 is provided with an elevator carrier 12 that conveys the pallets 20 and 90. The elevator transporter 12 is moved up and down the hoistway 10 by an elevating wire rope 14 wound by an elevating drive unit 13 provided at the upper part of the parking tower 2.

  On the other hand, the charging control device 51 includes a RAM, a ROM, a CPU, and the like, and a detection unit 61 by a non-contact type engagement confirmation means 70. This figure shows a state in which the lowermost photodetector 62 performs engagement confirmation by the non-contact type engagement confirmation means 70.

  The charging power source device 52 is provided with a switch 63, a power meter 64, and a breaker 65 for each storage shelf 11, and is supplied with power from an external power source 66. In this figure, the current collector 32 (power feeding unit) connected to the trolley wire 31 (power receiving unit) of the charging pallet 20 transferred from the elevator carrier 12 to the storage shelf 11 (storage unit) is connected to the charging power supply device 52. The lower switch 63 is connected by a power supply wiring 38. This example is a single-phase three-wire system. Further, the trolley wire 31 of the charging pallet 20 is connected to the relay stand 22 (relay unit) by the relay wiring 39. The relay wiring 39 is an L1 phase, an L2 phase, and a ground electrode.

  The branch wiring 73 from the L1 phase and the L2 phase of the relay wiring 39 is connected to the light emitting unit 71 (signal generation unit) installed at a predetermined position as the configuration on the charging pallet 20 side of the non-contact type engagement confirmation means 70. It is connected. A light receiving unit 72 (signal receiving unit) is provided on the storage shelf 11 side so as to face the light emitting unit 71. The light receiving unit 72 is connected to a detection unit 61 provided in the charge control device 51 by a wiring 74. As the light emitting unit 71, a phototube light projector and other light emitters (for example, a laser diode, an LED, a light bulb, etc.) are used. As the light receiving unit 72, a photoelectric tube light receiver and other light receivers (for example, a photodiode, Phototransistors, CCD elements, etc.) are used. The light emitting unit 71 and the light receiving unit 72 are installed so as to have a close positional relationship when the current collector 32 and the trolley wire 31 are engaged.

  In the case of such a photoelectric type, when the light receiving unit 72 of the storage shelf 11 detects lighting of the light emitting unit 71, voltage generation and current flow are generated in the light receiving unit 72. Thus, it can be detected that the trolley wire 31 (power receiving unit) of the charging pallet 20 and the current collector 32 (power feeding unit) of the storage shelf 11 are normally engaged.

  A plug 25 provided at one end of the charging cable 24 is connected to the outlet 23 provided in the relay stand 22, and a charging adapter 26 provided at the other end of the charging cable 24 is connected to a charging port of the electric vehicle EV. 27.

  The non-contact type engagement confirmation means 70 shown in FIG. 4 is an example of an optical configuration as shown in FIG. 5 (a), but the non-contact type engagement confirmation means 70 may be of other types. . An example is shown below.

  The non-contact type engagement confirmation means 70 of the second embodiment shown in FIG. 5B is an example of a magnetic type. In this case, a magnetic force line generator 75 (signal generator) is installed at a predetermined position of the charging pallet 20, and the branch line 73 from the relay wiring 39 is connected to the magnetic force line generator 75. The magnetic force generated by the magnetic line generator 75 may be a magnetic force generated by the relay wiring 39. On the other hand, a magnetic force line detection unit 76 (signal receiving unit) is installed at a predetermined position on the storage shelf 11 side so as to face the magnetic force line generation unit 75. As the magnetic line generator 75, a coil having an open magnetic path structure is used in which a magnetic field is generated when the trolley wire 31 and the current collector 32 are engaged and supplied with power. A coil (or a Hall element; an element that generates a Hall effect) that can detect the generated magnetic field is used. The magnetic force line generation unit 75 and the magnetic force line detection unit 76 are installed so as to be close to each other when the current collector 32 and the trolley wire 31 are engaged.

  In the case of such a magnetic system, a magnetic field detector (not shown) of the detection unit 61 detects that a magnetic field of the magnetic field generation unit 75 is detected by the magnetic field detection unit 76 on the storage shelf 11 side and a voltage is generated between the wirings 74. By detecting, it can detect that the electric power feeding means 30 of the charging pallet 20 and the storage shelf 11 are normally engaged.

  The non-contact type engagement confirmation means 70 of the third embodiment shown in FIG. 6A is an example of a sound wave (including ultrasonic wave) type. In this case, a sound wave generator 80 (signal generator) is installed at a predetermined position on the charging pallet 20, and the branch wiring 73 from the relay wiring 39 is connected to the sound wave generator 80. On the other hand, a sound collection unit 81 (signal reception unit) is installed at a predetermined position on the storage shelf 11 side so as to face the sound wave generation unit 80. As the sound wave generation unit 80, a piezoelectric element such as a speaker or a piezoelectric ceramic is used. As the sound collection unit 81, a piezoelectric element such as a microphone or a piezoelectric ceramic is used. The sound wave generation unit 80 and the sound collection unit 81 are installed so as to be close to each other in a state where the current collector 32 and the trolley wire 31 are engaged.

  In the case of such a sound wave type, a sound wave detector (not shown) of the detecting unit 61 indicates that the sound wave from the sound wave generating unit 80 is collected by the sound collecting unit 81 on the storage shelf 11 side and a voltage is generated between the wirings 74. ) To detect that the power supply means 30 between the charging pallet 20 and the storage shelf 11 is normally engaged.

  The non-contact type engagement confirming means 70 of the fourth embodiment shown in FIG. 6B is an example of a radio wave type. In this case, a radio wave transmission unit 85 (signal generation unit) is installed at a predetermined position of the charging pallet 20, and the branch wiring 73 from the relay wiring 39 is connected to the radio wave transmission unit 85. On the other hand, a radio wave receiver 86 (signal receiver) is installed at a predetermined position on the storage shelf 11 side. An antenna, a transmitter, or the like is used as the radio wave transmission unit 85, and an antenna, a receiver, or the like is used as the radio wave reception unit 86. In the case of this example, the radio wave receiver 86 may not be at the position of the storage shelf 11 as long as the radio wave from the radio wave transmitter 85 reaches. In addition, the number of radio wave transmission units 85 and radio wave reception units 86 may not be a pair, and one radio wave reception unit 86 may be provided for a plurality of radio wave transmission units 85.

  In the case of such a radio wave type, the radio wave receiving unit 86 on the storage shelf 11 side receives the radio wave from the radio wave transmitting unit 85 and voltage or current is generated between the wires 74, or the contact or the like is turned on. Is detected by a radio wave detector (not shown) of the detection unit 61, it can be detected that the power supply means 30 between the charging pallet 20 and the storage shelf 11 is normally engaged.

  Next, based on the flowchart shown in FIG. 7, the trolley wire 31 (power reception unit) of the charging pallet 20 and the current collector 32 ( A control method for detecting that the power supply unit is normally engaged will be described. This flowchart is an example in which the engagement confirmation is performed only for the charging pallet 20 on which the electric vehicle EV having a charging request is mounted. This is not subject to engagement confirmation. In the flowchart, the electric vehicle EV is simply referred to as “EV”.

  According to the elevator parking apparatus 1 described above, the trolley wire 31 on the charging pallet 20 side is the final stage in which the charging pallet 20 mounted with the electric vehicle EV requiring charging is transferred and stored in the storage shelf 11 and stopped at a predetermined position. Is in contact with the current collector 32 on the storage shelf 11 side. At this time, the light emitting unit 71 is disposed close to the light receiving unit 72.

  First, it is determined whether or not the storage / transfer of the charging pallet 20 is in progress (S1). If it is not in the middle of transfer / transfer, it is determined whether or not the storage / transfer has been completed (S2). ). If it is determined by this determination that the storage transfer has been completed, the charging control device 51 closes the switch 63 of the charging power supply device 52 (S3), and charges the electric vehicle EV requested to be charged. At the same time, the operation of confirming the engagement of the power feeding means 30 is started.

  When the switch 63 is closed, when the current collector 32 and the trolley wire 31 are completely engaged, the light emitting unit 71 (photoelectric tube or the like) is energized through the branch wiring 73 of the relay wiring 39. Therefore, the light emitting unit 71 emits light. If the light receiving unit 72 detects the light emission of the light emitting unit 71 (S4), the current collector 32 (power feeding unit) and the trolley wire 31 (power receiving unit) are “electrically completely engaged”. To be judged. Then, a closing maintenance command for the switch 63 is issued (S5), and charging is continued. Thereafter, when the battery is fully charged, the switch 63 is automatically opened and charging is terminated.

  On the other hand, when the current collector 32 and the trolley wire 31 are poorly engaged, the light emitting portion 71 is not energized because it is electrically disconnected at the poorly engaged portion although the switch 63 is closed. . Therefore, in the above determination (S4), the light receiving unit 72 does not detect the light emission of the light emitting unit 71, and it is determined as “electrically poor engagement”.

  In this way, when it is determined that “electrically poor engagement”, the charging control device 51 issues a retry command for transferring the charging pallet 20 (S6), and until a predetermined number of retries (for example, two times) is reached (S7) After opening the switch 63 and interrupting the engagement confirmation (S8), the operations after (S1) are repeated. After that, when the number of retries reaches N times (for example, 2 times) and “engagement failure” occurs (S7), the charging control device 51 issues an opening command (engagement stop) to the switch 63 ( S9), “engagement failure alarm” (maintenance check notification, etc.) is issued (S10).

  In the flowchart of FIG. 7, a process of performing “transfer retry” of the charging pallet 20 in the case of “unsatisfactory” is included, and therefore the current collector 32, the trolley wire 31 itself, and the mounting structure thereof “ In the case of “engagement failure” caused by a deviation of the stop position due to an unbalanced load or the like associated with mounting of the electric vehicle EV on the charging pallet 20 instead of “failure engagement”, the “engagement failure” is indicated by “transfer retry”. It can be eliminated and charged. The “transfer retry” may be omitted.

  Next, on the basis of the flowchart of FIG. 8, in addition to the “engagement confirmation” performed on the charging pallet 20 on which the electric vehicle EV requested to be charged in the flowchart of FIG. An example of performing “confirmation of engagement” when the charging pallet 20 and the empty charging pallet 20 are also stored in the storage shelf 11 will be described.

  First, it is determined whether or not the charging pallet 20 has been transferred to the charging storage shelf 11 and stopped (S11). If the stopping is completed, a closing instruction for the switch 63 is issued (S12), and the power supply means The operation of 30 confirmation of engagement is started.

  When the current collector 32 and the trolley wire 31 are completely engaged by closing the switch 63, the light emitting unit 71 is energized to emit light. If the light receiving unit 72 detects the light emission of the light emitting unit 71 (S13), the current collector 32 (power feeding unit) and the trolley wire 31 (power receiving unit) are “electrically completely engaged”. To be judged. Thereafter, it is determined whether or not the charging request electric vehicle EV is mounted on the charging pallet 20 (S14). If the charging request electric vehicle EV is mounted, a closing maintenance command for the switch 63 is issued. When the battery is discharged (S15), charging of the electric vehicle EV is started, and when the battery is fully charged, the switch 63 is automatically opened and the charging is finished.

  If the electric vehicle EV requiring charging is not installed in the determination of (S14), the opening command is sent to the switch 63 because the empty charging pallet 20 or the electric vehicle EV not requiring charging is installed. Is issued (S16), and the engagement confirmation is completed.

  On the other hand, when the light receiving unit 72 does not detect the light emission of the light emitting unit 71 in the determination of (S13), it is determined as “electrically poor engagement”, and the charging control device 51 retries the transfer of the charging pallet 20. A command is issued (S17), and until the predetermined number of retries (for example, 2 times) is reached (S18), the switch 63 is opened and the engagement confirmation is interrupted (S19), and then the above (S11) Subsequent operations are repeated. After that, even if the number of retries reaches a predetermined number of times, if “engagement failure” occurs (S18), the charging control device 51 issues an opening command (engagement stop) to the switch 63 (S20). A "failure alarm" (maintenance check notification, etc.) is issued (S21).

  In this way, with respect to the charging pallet 20 that is not charged, the aged deterioration of the constituent members (the current collector 32 and the trolley wire 31, the plug 40 and the outlet 43, the internal wiring, etc.) of the power feeding means 30 (power feeding unit / power receiving unit). It is possible to detect in advance physical and electrical engagement failures due to (abrasion) and disconnection, and to make it useful for an engagement confirmation inspection during maintenance inspection.

  As described above, according to the elevator parking apparatus 1, the non-contact type engagement confirmation means 70 is employed as the engagement confirmation means for the power supply means 30 (the current collector 32 and the trolley wire 31). It is not necessary to provide a physical connection means for detection between the storage shelf 11 and the charging pallet 20, and the power supply means 30 (the current collector 32. The engagement of the trolley wire 31) can be reliably confirmed.

  In addition, by adopting non-contact type means as the engagement confirmation means, the existing mechanical parking apparatus can be easily modified by simple additional work, and the reliability of the charging function can be greatly improved.

  Furthermore, in the power supply means 30 of the above-described embodiment, the current collector 32 (power supply unit) is provided on the storage shelf 11 side, and the short trolley wire 31 (power reception unit) is disposed on the charging pallet 20 side. Even in the system, it is possible to charge the charging amount for the charging pallet 20 for each storage shelf 11 by providing the power amount meter 64 for each storage shelf 11, and the fairness of charging only between parking and parking and charging users Can be improved.

  In the above embodiment, the elevator parking apparatus 1 has been described as an example. However, any system (for example, a vertical circulation system, a horizontal circulation system, a vertical circulation system, a mechanical parking apparatus including a pallet for mounting an electric vehicle) may be used. A box-type circulation type, a circular circulation type, a multistage type, a plane reciprocating type, and the like are also applicable, and the type of the mechanical parking device is not limited to the above-described embodiment.

  Further, in the above-described embodiment, the “optical type”, “magnetic type”, “sonic wave / ultrasonic type”, and “radio wave type” have been described as examples of the non-contact type engagement confirmation unit 70. The combination confirmation unit 70 may have another configuration as long as it is a unit that can confirm engagement without contact, and is not limited to the above embodiment.

  Furthermore, the above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention, and the present invention is not limited to the above-described embodiment.

  The mechanical parking apparatus provided with the charging function according to the present invention can be used for a parking apparatus that reliably confirms the engagement between the power feeding unit on the housing side and the power receiving unit on the charging pallet side.
