As a result, the elevator floor is held flush with the vehicle entry surface by the elevator means when the vehicle enters and exits the pallet in a state where it is arranged at the substantially central portion of the berth. It is designed to function as a platform. On the other hand, when the pallet is laterally fed between the berth portion and the lift device by the pallet lateral feeding device, the lifting floor is lowered to a position lower than the lower surface of the pallet by the lifting means. It is made to evacuate from the movement route.

  By the way, as another type of mechanical parking apparatus, a circulation path comprising two upper and lower horizontal transfer paths and lift lifts provided at both ends thereof is provided to circulate a pallet for mounting a vehicle. A box-type circulation type mechanical parking device is known.

  In this type of box-type circulation type mechanical parking device, when the direction of boarding the vehicle and the orientation of the vehicle retracted posture inside the parking device are different by 90 degrees, they are adjacent to the side of one lifting lift in the circulation path. Conventionally, it has been proposed to provide a loading / unloading section (berth section) and a means for causing the loading / unloading section to change the direction of the vehicle.

  The means for changing the direction of the vehicle is, for example, a rectangle in which a deck arranged on both the left and right sides in the vehicle entry direction is provided on the floor surface of the loading / unloading unit, and a pallet fits between the decks. And a lifting and turning device having a pallet lifting function and a turning function is provided in a pit below the opening. Furthermore, a transition rail located on the extended line of the upper horizontal transfer path is provided on the floor surface of the loading / unloading section so as to be positioned between the circulation path and the lifting swivel device. As a result, the pallet placed in the opening between the decks can be lifted by the lifting and swiveling device and turned 90 degrees, and the pallet after changing the orientation is placed on the crossing rail. I can do it.

  Further, when the pallet with the changed direction is placed on the crossing rail, it is locked with another pallet pushed out along the crossing rail from the upper horizontal transfer path of the circulation path. The pallet is laterally fed so as to be drawn into the circulation path together with the other pallet by the traversing device of the upper horizontal traversing path (see, for example, Patent Document 1).

  On the other hand, the pallet mounting portion 20 of the swivel floor 19 is bent downward and protrudes by a certain amount to the lower surface side of each end edge corresponding to the arrangement of the respective swivel floor support columns 23 and 23a. In this configuration, the projection 24 is provided. As a result, the swivel floor 19 is configured so that the load transmitting protrusions 24 are provided on the swivel floor support pillars 23 and 23a in a state where the pallet placing part 20 is disposed along the vertical pallet receiving port 6a. It is supposed to be received on the top. Therefore, in this state, the pallet 5 placed on the pallet placing portion 20 of the swivel floor 19 has a portion of the berth portion 1 near the entrance 2 of the swivel floor support column 23 and the swivel floor 19. It is supported from below via the pallet placing portion 20 and the load transmitting projection 24.

  Further, the swivel floor 19 is swung 90 degrees as described above, and in the state where the pallet placing portion 20 is disposed along the lateral pallet accommodating port 6b, the swivel floor 19 is aligned along the vertical pallet accommodating port 6a. The entire swivel floor 19 is placed in the berth pit 9 up to a height position at which the lower surface side of each platform forming plate 21 comes to contact the upper ends of the respective swivel floor support columns 23, 23a. It can be lowered. Therefore, in the state where the swivel floor 19 is lowered into the berth pit 9 as described above, the pallet 5 delivered from the swivel floor 19 to each pallet lateral feed device 11 does not interfere with the swivel floor 19. It is designed to be able to feed horizontally.

Before being sent to the lift device 4, the direction in which the vehicle c enters the berth portion 1 can be changed by 90 degrees.

  Therefore, the vehicle c placed on the pallet 5 that transports the hoistway 3 by the lift device 4 performs entry and exit of the storage layer of the vehicle storage layer in the same manner as a conventional mechanical parking device. Can do. Therefore, in the mechanical parking device of the present invention, the direction in which the vehicle enters the berth portion 1 and the orientation of the vehicle retracted posture inside the parking device can be different by 90 degrees.

  Furthermore, each pallet lateral feed device 11 used for laterally feeding the pallet 5 between the berth portion 1 and the lifting device 4 of the hoistway 3 can be configured to be installed in the berth portion pit 9. The thing of the structure similar to the pallet cross-feed apparatus used with the conventional mechanical parking apparatus can be used.

  Therefore, the mechanical parking apparatus of the present invention has a configuration limited to the box-type circulation type mechanical parking apparatus as shown in Patent Document 1, or a dedicated pallet as shown in Patent Document 2. A transfer device can be dispensed with.

  In addition, this invention is not limited only to the said embodiment, In the said embodiment, the entrance / exit 2 of the said berth part 1 is made about the pallet 5 arrange | positioned in the vertical pallet accommodation port 6a of the berth part 1. FIG. As the load support means 22 for supporting the close portion from below, the swivel floor support column 23 that supports the pallet 5 indirectly through the support of the swivel floor 19 is exemplified. The load support means 22 may be employed.

  That is, another example of the structure of the load support means 22 is, for example, the surface of the platform 8 at a position that is a peripheral portion of the vertical pallet receiving port 6a near the entrance / exit 2 of the berth portion 1 in the platform 8. At a position lower than the thickness of the pallet 5 by an actuator so that the actuator protrudes toward the inside of the vertical pallet receiving port 6a so that the outer peripheral portion of the pallet 5 can be locked from above and supported. It is good also as a structure provided with the latching means of the nail | claw shape etc. which can switch the storing attitude | position which does not protrude inside the pallet accommodation port 6a. In the retracted state, the locking means does not interfere with the vertical pallet receiving port 6a when passing the platform forming plate 21 of the swivel floor 19 in the vertical direction. The same entry / exit processing of the vehicle c can be performed.

  Another example of the structure of the load support means 22 is, for example, an upper end of the platform 8 directly below the vertical pallet receiving port 6a in the berth part pit 9 and near the entrance 2 of the berth part 1. As a configuration in which a pallet support column is erected at a position lower than the surface by the thickness dimension of the pallet 5, a portion near the entrance / exit 2 of the berth portion 1 in the pallet 5 disposed in the vertical pallet receiving port 6a You may make it support directly with a support pillar. In the case of this configuration, the pallet placing portion 20 of the swivel floor 19 has a shape that does not interfere with the pallet support pillar when the pallet placement portion 20 is disposed in the vertically oriented pallet receiving port 6a. The forming plate 21 is provided with a door that opens only on the upper surface side at a portion that interferes with the pallet support column when the platform forming plate 21 is lowered to the berth pit 9 through the vertical pallet receiving port 6a. What is necessary is just to set it as the structure provided with the opening part. Also with this configuration, the same entry / exit processing of the vehicle c as in the above embodiment can be performed.

  Further, as in each of the above-described configuration examples, the portion near the entrance / exit 2 of the berth portion 1 in the pallet 5 arranged in the vertically oriented pallet receiving port 6a is arranged on the platform 8 and the berth portion without the swivel floor 19 therebetween. When the pit 9 is configured to be supported directly via a predetermined member, the planar shape of the pallet placing part 20 on the swivel floor 19 supports the pallet 5 placed on the pallet placing part 20. If possible, the shape of the pallet 5 need not be extended in the longitudinal direction. Therefore, in this case, the planar shape of the swivel floor 19 is not necessarily a cross shape.

  The mechanical parking apparatus of the present invention is provided with a hoistway 3 on the opposite side of the entrance / exit 2 of the berth part 1 for loading and unloading of the vehicle c, the hoistway 3 is provided with a lift device 4, and the above A pair of pallets for laterally feeding between the berth part 1 and the lift device 4 in a state where each short side portion of the pallet 5 for vehicle placement is supported on the berth part pit 9 provided below the berth part 1 As long as it is a mechanical parking device of the type provided with the lateral feed device 11, it may be applied to any type of flat-reciprocating mechanical parking device, and further to a mechanical parking device other than the flat-reciprocating method. May be.

  Of course, various modifications can be made without departing from the scope of the present invention.
