Using the force, the tower side connector 7 is pressed against the pallet side connector 6 to maintain the connection state of both connectors.

  At this time, as shown in FIG. 6, the holding unit 40 is configured such that the magnet 41 is attracted to the side protrusion 3 b of the pallet 3 in a state where the tower-side connector 7 and the pallet-side connector 6 are connected. 3 is held at the storage position P with a predetermined holding force.

  The holding force for holding the pallet 3 at the storage position P (that is, the attracting force of the magnet 41) by the holding unit 40 is set to be stronger than the urging force of the first elastic member 21. For this reason, even when the pallet 3 is released from the predetermined storage position P due to the restoring force of the first elastic member 21 of the follow-up mechanism 16 when the pallet 3 is fixed by the lock mechanism, the magnet 41 does not move. A stopper plate 45 that is attracted to the side protrusion 3b of the pallet 3 and connected to the magnet 41 via the mounting plate 44 and the support bar 43 comes into contact with the standing wall 47a, and the side protrusion 3b of the magnet 41 Restrict movement in the direction toward. As a result, the pallet 3 can be prevented from being displaced or detached from the predetermined storage position P. As a result, an engaging member such as a claw of a lateral feeding device that laterally feeds the pallet 3 is normally engaged with a predetermined engaged portion formed on the pallet 3 and the pallet 3 is pulled out from the storage position P. Is possible.

  On the other hand, when the pallet 3 is moved from the storage position P, an operation of pulling the pallet 3 from the storage position P and releasing the connection between the tower-side connector and the pallet-side connector using the above-described engaging members such as claws. By applying a force (that is, an operating force larger than the holding force of the holding unit 40), the holding of the pallet 3 by the holding unit 40 can be released.

  Further, when the pallet 3 is transferred to a position facing the storage unit 5, the pallet-side connector 6 is more than the tower-side connector 7 due to a manufacturing error in the tower 2 or the like or deformation of the pallet 3. When there is a positional shift that is in the lower position, when the pallet 3 is laterally moved, the tip of the peripheral wall plate 12 provided at the lower part of the pallet side connector 6 is connected to the tower side connector 7. By making it contact with the guide part 25a of the surrounding wall board 25 provided in the lower part of this, the pressing force which presses this downward is applied.

  In response to the pressing force, the tower side connector 7 and the support plate 23 supporting the tower side connector 7 are displaced downward, and the support bar 20 is inclined to lower the tower side connector 7 and the support plate 23 etc. Thus, it is possible to correct the positional deviation between the two connectors 6 and 7 so that the connectors 6 and 7 are properly opposed to each other. In this state, the pallet 3 is further laterally moved, so that the positioning pins 13 protruding from the holding bracket 11 of the tower side connector 7 are inserted into the positioning holes 26 formed in the holding bracket 24 of the tower side connector 7. The connecting terminal 6a protruding from the pallet side connector 6 and the connecting hole 7a formed in the tower side connector 7 can be accurately positioned.

  When the pallet-side connector 6 is displaced laterally from a position directly facing the tower-side connector 7 in a plan view, one side of the pallet-side connector 6 according to the lateral feed operation of the pallet 3 The front end portion of the peripheral wall plate 12 provided in the side portion is brought into contact with the guide portion 25a of the peripheral wall plate 25 provided in one side portion of the tower side connector 7 and pressed in the direction indicated by the arrow X in FIG. By applying the pressing force to be applied, the positional deviation between the connectors 6 and 7 is corrected.

  In the state where the pallet side connector 6 and the tower side connector 7 are accurately positioned in accordance with the lateral feed operation of the pallet 3 as described above, the connection terminal 6a of the pallet side connector 6 is inserted into the connection hole 7a of the tower side connector 7. Thus, both connectors 6 and 7 can be automatically and properly connected.

  When the tower 2 vibrates and the pallet 3 and the pallet-side connector 6 are shaken in the connected state of the connectors 6 and 7, the follower mechanism 16 expands and contracts the first elastic member 21 and By tilting and displacing the support bar 20, the tower side connector 7 can be displaced by following the pallet side connector 6. In addition, the tower-side connector 7 is supported by a bushing member 19 that supports the support bar 20 in a tiltable manner, and a tiltable universal joint 22 that flexibly connects the tip of the support bar 20 and the support plate 23. It is possible to allow the parallel movement while maintaining the set angle.

In this state, the pallet 3 can be held at the storage position P by the holding force of the holding unit 40. As a result, when the pallet 3 is in the storage position P, it is possible to avoid the pallet 3 being displaced or detached from the predetermined storage position P due to the restoring force of the first elastic member 21 of the tracking mechanism 16.

  For example, in the above embodiment, in a state in which the pallet 3 is fixed at the storage position P by a lock mechanism (not shown), the first elastic member 21 is slightly contracted, and the restoring force of the first elastic member 21 is used to make the tower The side connector 7 is pressed against the pallet side connector 6 to maintain the connection state of both the connectors 6 and 7. When the pallet 3 is moved from the storage position P, the side protrusion 3b of the pallet 3 is attracted by the magnet 41 of the holding unit 40 even if the pallet 3 is fixed by the lock mechanism. It is held at position P. Therefore, the possibility that the pallet 3 is misaligned or detached from the storage position P due to the restoring force of the first elastic member 21 is avoided.

  This makes it possible for an engaging member such as a claw for conveying the pallet 3 to normally engage with a predetermined engaged portion formed on the pallet 3, resulting in poor work with respect to the movement operation of the pallet 3. Can be avoided.

  On the other hand, when the pallet 3 is moved, the operation force for pulling the pallet 3 from the storage position P and releasing the connection between the tower-side connector 6 and the pallet-side connector 7 using an engaging member such as the above-mentioned claw is used. By making it act, holding | maintenance of the pallet 3 by the holding | maintenance part 40 can be cancelled | released.

In the electrical connection structure for a multi-story parking apparatus according to this embodiment, since the holding portion 40 includes the magnet 41, when the pallet 3 is in the storage position P, the magnet 41 is a side protruding portion at the end of the pallet 3. The pallet 3 can be reliably held by being adsorbed to 3b. In addition, since the holding unit 40 has a simple structure that does not have an electrically operating mechanism, it is possible to reduce manufacturing costs and running costs.

(4)
In the electrical connection structure for a multi-story parking apparatus according to the present embodiment, the holding portion 40 includes the second elastic member 42 on the tower side, so that the magnet 41 is moved to the end side of the pallet 3 by the second elastic member 42. It is possible to bias in the direction of pressing toward the side protrusion 3b. Thereby, it is possible to relieve the impact when the side protrusion 3b at the end of the pallet 3 moving to the storage position P collides with the magnet 41 stationary on the tower side by the second elastic member 42. . Thereby, it is possible to prevent damage to the magnet 41 and its peripheral part.

(5)
In the electrical connection structure for the multi-story parking apparatus of the present embodiment, the magnet 41 receives the biasing force of the second elastic member 42 and is attracted to the side protrusion 3b at the end of the pallet 3 at the storage position P. Since the movement of the magnet 41 is restricted by the stopper plate 45, which is a restricting member, even if trying to move further in the direction of pressing toward the side protrusion 3b at the end, the second elastic member 42 is provided. Also in the configuration, the magnet 41 can be attracted to the side protrusion 3 b at the end of the pallet 4 and the pallet 3 can be reliably held at the predetermined storage position P.

(Modification)
In the above embodiment, the entire pallet 3 is manufactured from a magnetic material such as a steel plate that can be attracted to a magnet, but the present invention is not limited to this. It is only necessary that at least the end of the pallet 3 at a position facing the magnet is made of a magnetic material.

  Moreover, although the holding part 40 of the said embodiment is equipped with the 2nd elastic member 42 which urges | biases the magnet 41 to the direction which presses the side protrusion part 3b of the edge part of the pallet 3, the said 2nd elastic member 42 is provided. Can be omitted. Further, the magnet 41 may be fixed to the standing wall 47a of the first bracket 47 so that it cannot be displaced in the feed direction Y of the pallet 3.

  Furthermore, in said embodiment, although the holding part 40 provided with the magnet 41 which adsorb | sucks the side protrusion part 3b of the pallet 3 is mentioned as an example, this invention is not limited to this, If it is a structure which hold | maintains a pallet, it is possible to employ | adopt the holding | maintenance part of a various aspect.

  For example, the holding portion shown in FIGS. 7A to 7C is attached to the upright wall 18a of the support bracket 18 fixed to the tower 2 (see FIG. 2) side. The holding portion includes a movable piece 61 that can be engaged with the side protrusion 3b of the pallet 3, an elastic member 62 that urges the movable piece 61 in a direction toward the side protrusion 3b, and a support bar 63. , A fixed plate 64, a support shaft 65, and a mounting plate 66.

  The movable piece 61 has a protruding portion 61a that protrudes upward. The protruding portion 61a has a mountain shape or an arch shape having a pair of oblique sides. One end of the movable piece 61 is supported by a support shaft 65 extending in the horizontal direction so as to be able to rotate in the vertical direction. The support shaft 65 is attached to the upright wall 18 a of the support bracket 18 via the attachment plate 66. The end 61b on the distal end side of the movable piece 61 is bent to the lower side of the protrusion 61a, and the upper end of the support bar 63 is connected. The lower end portion 63 a of the support bar 63 passes through the fixing plate 64 attached to the upright wall 18 a and is positioned below the fixing plate 64. The lower end 63 a is formed wider than the through hole 64 a of the fixed plate 64. The elastic member 62 is made of a coil spring or the like, and is disposed between the end portion 61 b of the movable piece 61 and the fixed plate 64 in a constantly compressed state. As shown in FIG. 7A, the movable piece 61 and the support bar 63 are urged upward by the elastic member 62. However, the movable piece 61 and the support bar 63 are movable when the lower end 63a of the support bar 63 abuts against the fixed plate 64a. The position at which the piece 61 and the support bar 63 can move to the uppermost position is restricted.

  In the holding part configured as described above, when the pallet 3 moves to the storage position as shown in FIGS. 7A to 7C (that is, the direction approaching the upright wall 18a in FIG. 7 (left direction)). ), The side protrusion 3b of the pallet 3 abuts against the protrusion 61a of the movable piece 61, thereby pushing the movable piece 61 downward while resisting the upward biasing force of the elastic member 62. After the side protrusion 3b passes through the apex of the protrusion 61a, the movable piece 61 returns upward due to the biasing force of the elastic member 62. Thereby, when the pallet 3 is in the retracted position, the side protrusion 3b of the pallet 3 engages with the protrusion 61a of the movable piece 61, and the pallet 3 is held by the holding portion with a predetermined holding force. On the other hand, holding the pallet 3 by the holding unit by applying an operation force larger than the holding force of the holding unit to the pallet 3 in the direction of releasing from the storage position using an engaging member such as the above-described claw. Can be released.

  As another modification of the present invention, as shown in FIG. 8, a holding portion including a pair of engaging portions 71 and 72 may be employed. That is, the holding portion is provided on the pallet side engaging portion 71 provided on the side end portion 3c of the pallet 3 and on the standing wall 18a of the support bracket 18 on the tower 2 (see FIG. 2) side. And an engaging portion 72.

  The pallet side engaging portion 71 has a tip portion 71a that bulges locally. The base side end of the pallet side engaging portion 71 is connected to the outer surface of the side end 3 c of the pallet 3.

  On the other hand, the tower side engaging portion 72 is made of an elastically deformable material such as rubber or resin, and has a pair of claw portions 72a that are spaced apart from each other and face each other. Inside the tower side engaging part 72, a space part 72c for accommodating the tip part 71a of the pallet side engaging part 71 is formed. The space 72c communicates with the outside through a gap 72b between the pair of claw portions 72a. The tower side engaging portion 72 is fixed to the standing wall 18a of the tower side support bracket 18 via the bracket 73 so that the gap 72b between the pair of claw portions 72a faces the pallet 3 side.

  In the holding part configured as described above, when the pallet 3 moves to the storage position as shown in FIG. 8 (that is, when it moves in the direction approaching the upright wall 18a in FIG. 8), the pallet 3 side The tip end portion 71a of the pallet-side engaging portion 71 is inserted into the gap 72b between the pair of claw portions 72a of the tower-side engaging portion 72 fixed to the tower side. While resisting, the gap 72b between the pair of claws 72a is pushed wide. After the tip 71a passes through the gap 72b, the pair of claws 72a returns to the initial position by the elastic force of the tower side engaging portion 72. Thus, when the pallet 3 is in the retracted position, the pallet side engaging portion 71 on the pallet 3 side engages with the tower side engaging portion 72 on the tower side, and the pallet 3 is held with a predetermined holding force by the holding portion. Is done. On the other hand, holding the pallet 3 by the holding unit by applying an operation force larger than the holding force of the holding unit to the pallet 3 in the direction of releasing from the storage position using an engaging member such as the above-described claw. Can be released.

  As described above, in the holding portion shown in FIG. 8, when the pallet 3 is in the retracted position, the pallet-side engaging portion 71 and the tower-side engaging portion 72 are engaged with each other, so that the pallet 3 is securely attached. Can be held. In addition, since such a holding portion has a simple structure that does not have an electrically operating mechanism, manufacturing costs and running costs can be reduced. In addition, the aspect which mutually replaced the structure of the pallet side engaging part 71 and the structure of the tower side engaging part 72 may be sufficient.

  In addition, you may arrange | position the holding | maintenance part of the above-mentioned various aspect not only to the upper side of the tower side connector 7, but one place or several places in another position.
