Japanese Patent No. 3449669 Japanese Patent No. 3947063 Japanese Patent Laid-Open No. 2008-8003

FIG. 1 is a front view of an uneven pallet 1A and a conventional flat pallet 1B. FIG. 1A shows the uneven pallet 1A, and FIG. 1B shows the flat pallet 1B.
On the side surfaces of the uneven pallet 1A and the flat pallet 1B, there are provided transverse grooves 2 that extend horizontally in the longitudinal direction and open downward.
Hereinafter, the conventional flat pallet 1B is referred to as an “old flat pallet 1B”.

2A and 2B are front views of the cage 3 on which the uneven pallet 1A and the old flat pallet 1B are mounted. FIG. 2A shows the case of the uneven pallet 1A, and FIG. 2B shows the case of the old flat pallet 1B.
In the traversing grooves 2 of the pallets 1A and 1B, horizontal traversing pins (traversing pins 4) of a traversing device (so-called register mark mechanism) on the cage 3 are engaged from below, and the traversing grooves 2 and the traversing pins 4 As a result of the engagement, the uneven pin 1A and the old flat pallet 1B are horizontally traversed.

In FIG. 2, at the entrance / exit, the entrance height H1 (the height of the roadway at the entrance / exit entrance) and the height of the road surface 5 of the pallets 1A, 1B (the tires of the car) so that the car can enter and exit smoothly. The height of the surface to be mounted) must match.
In the conventional concavo-convex pallet 1A, the concavo-convex pallet 1A has an uneven surface, and the concavo-convex pallet 1A has high bending rigidity due to the concavo-convex. Therefore, as shown in FIG. The height a1 (for example, 130 mm) up to the vehicle road surface 5 was set relatively low.
On the other hand, the old flat pallet 1B having a flat upper surface has the same upper end height of the above-described traverse groove 2, and this portion does not protrude upward from the road surface 5, so as shown in FIG. The height a2 (for example, 230 mm) from the upper surface of the traversing rail on the cage to the road surface 5 of the pallet was relatively high.

Therefore, when stopping the cage at the loading / unloading port, it is necessary to change the stop height of the stopper 7 provided in the cage 3 between the uneven pallet 1A and the old flat pallet 1B as shown in FIG.
For example, in the example of FIG. 2A, when the stop height of the lower surface of the stopper 7 provided in the cage 3 is b1 (for example, 90 mm) from the entry height, in the example of FIG. It was necessary to set the stop height of the lower surface to b2 (for example, 90 + 230−130 = 190 mm) larger than b1 from the boarding height.
Therefore, conventionally, it was necessary to provide two sets of dog retracting devices 8 respectively corresponding to the uneven pallet 1A and the old flat pallet 1B at the entrance / exit, and to perform different controls corresponding to each.
In order to support the four corners of the cage 3, the dog haunting device 8 is usually a set of four units. Therefore, it is necessary to provide a total of eight dog retracting devices 8 at the entrance / exit, and there is a problem that the structure and control at the entrance / exit are complicated.

  For this reason, it is difficult to mix the uneven pallet and the flat pallet, particularly in an intermediate-loading type elevator parking device in which the entrance / exit is in the middle of the cage hoistway and no fixed dog is provided at the intermediate position.

  The present invention has been developed to solve the above-described problems. That is, the object of the present invention is to allow the uneven pallet and flat pallet to be mixed, and to make the stop height of the cage common at the entrance / exit. It is an object of the present invention to provide an elevator-type parking apparatus that can reduce the number, simplify the structure, and facilitate the control.

According to the present invention, a plurality of storage shelves provided in the vertical direction adjacent to the widthwise end of the cage hoistway extending in the vertical direction, the cage for raising and lowering the cage hoistway, and the cage attached to the cage An elevator-type parking device comprising a traverse rail for guiding the traversal of a pallet on which a car is placed, and a traverse device attached to the cage and traversing the pallet between the storage shelves,
The pallet is composed of an uneven pallet with unevenness on the upper surface and a flat pallet with a flat upper surface, and has lateral grooves that extend horizontally in the longitudinal direction on each side surface and open downward.
The uneven pallet and the flat pallet have the same height from the upper surface of the traverse rail to the road surface on which the vehicle is mounted, and the traverse groove of the flat pallet does not protrude upward from the upper surface. It is provided at a position lower than the transverse groove,
The traversing device includes a horizontal swiveling device that horizontally swivels a traversing pin engaged with a traversing groove, and a lifting device that lifts and lowers the horizontal swiveling device on a cage,
There is provided an elevator parking apparatus characterized in that a horizontal turning device is moved up and down in accordance with the height of the traversing groove by a lifting device.

According to the above configuration of the present invention, the uneven pallet and the flat pallet of the present invention have the same height from the upper surface of the traverse rail to the road surface on which the vehicle is placed, so the cage is stopped at the entrance / exit In this case, the stop height of the stopper provided in the cage is the same for the uneven pallet and the flat pallet.
Therefore, the stop height of the cage at the loading / unloading port can be made common, thereby reducing the required number of dog retracting devices required at the loading / unloading port.

On the other hand, the traversing groove of the flat pallet of the present invention is provided at a position lower than the traversing groove of the uneven pallet so as not to protrude upward from its upper surface, but is adjusted to the height of the traversing groove by an elevating device. To move the horizontal swivel up and down. Accordingly, in both cases of the uneven pallet and the flat pallet, the pallet can be traversed between the storage shelf by horizontally traversing the traversing pin engaged with the traversing groove by the horizontal pivoting device.
Therefore, depending on the type of pallet (uneven pallet or flat pallet), the concavo-convex pallet and flat pallet can be mixed by simply raising and lowering the horizontal swivel device by a lifting device to a predetermined height, simplifying the structure and controlling it. It can be simplified.

Therefore, even in an intermediate parking type elevator parking apparatus in which a fixed dog cannot be provided in the middle of the cage hoistway, the uneven pallet and the flat pallet can be easily mixed.
Further, in the case of a parallel type elevator type parking apparatus, by providing a flat pallet for a roadway, it is not necessary to install an elevating floor, which makes it possible to reduce costs and shorten the construction period.

The string member 14b extends vertically upward, and the string member 14b can be wound and unwound by a hoisting device (not shown) installed in the upper part of the apparatus.
The cage central portion 14c moves up and down along the cage hoistway 11 by winding and lowering the string member 14b.

  In this example, the storage shelf 12 is provided with a mixture of a storage shelf 12a for a normal vehicle having a storage height for a normal vehicle and a storage shelf 12b for a high roof vehicle having a storage height for a high roof vehicle. .

The elevator type parking apparatus 10 of FIG. 3 is located on the front side and the back side, and is composed of two elevator type parking apparatuses (vertical type elevator type parking apparatus described above) set at the same height where the entrance / exit is continuous. The elevator type parking apparatus of the near side is shown.
At least one flat pallet 1C of the elevator parking device 10 on the front side can be placed on a cage that stops at the entrance / exit of the front side, and the car can travel on its own and pass to the entrance / exit on the back side. This is a flat pallet 1C for a rough road.
The flat pallet 1C for the roadway is substantially the same in shape although the usage is different from the flat pallet 1C for storage.
Hereinafter, the flat pallet 1C of the present invention is referred to as “new flat pallet 1C”.

  At least one storage shelf 12 of the elevator parking device 10 on the near side of the tandem elevator parking device is a high roof vehicle storage shelf 12b having a storage height for a high roof vehicle. Further, a storage shelf 12c for a roadway for storing a new flat pallet 1C for a roadway with a storage height for an ordinary vehicle is provided above the storage rack 12b for the high roof vehicle.

  4A and 4B are front views of the uneven pallet 1A and the new flat pallet 1C of the present invention. FIG. 4A shows the uneven pallet 1A, and FIG. 4B shows the new flat pallet 1C. The uneven pallet 1A is the same as the conventional uneven pallet 1A shown in FIG. 1, but the new flat pallet 1C is different from the conventional old flat pallet 1B shown in FIG.

On the side surfaces of the pallets 1A and 1C, there are provided transverse grooves 2 that extend horizontally in the longitudinal direction and open downward.
Further, the uneven pallet 1A and the new flat pallet 1C have the same height a1, a3 from the upper surface of the traversing rail 16 to the road surface 5 on which the vehicle is placed.
Furthermore, the traverse groove 2 of the new flat pallet 1C is provided at a position lower than the traverse groove 2 of the uneven pallet 1A so as not to protrude upward from the upper surface thereof. That is, the traverse groove 2 of the new flat pallet 1C is set to a height h (for example, 100 mm) lower than the traverse groove 2 of the uneven pallet 1A.

  Accordingly, in FIG. 3, the stop height of the lower surface of the stopper 7 provided on the cage suspension 14a of the cage 14 is b1 (for example, 90 mm) from the entry height H1 and is the same for the uneven pallet 1A and the new flat pallet 1C. It is.

  5A and 5B are explanatory diagrams of the traversing device 20, in which FIG. 5A shows the traversing of the uneven pallet 1A, and FIG. 5B shows the traversing of the new flat pallet 1C. In each figure, the uneven pallet 1A and the new flat pallet 1C are not shown.

  5A and 5B, the traversing device 20 includes a horizontal swiveling device 22 that horizontally swivels the traversing pins 21 that engage with the traversing grooves 2 (not shown) of the pallets 1A and 1C, and a horizontal swirling device. And a lifting device 30 that lifts and lowers 22 on the cage 14.

The traversing pin 21 is, for example, a cylindrical roller that freely rotates about a vertical axis.
The horizontal turning device 22 includes, for example, a turning drive device 23, a turntable 24, and a horizontal member 25. The turning drive device 23 includes, for example, a ring gear fixed to the turntable 24 and a motor that rotationally drives a pinion gear that meshes with the ring gear.
The horizontal member 25 has a traversing pin 21 fixed to the upper surface of the tip and a terminal fixed to the outer surface of the turntable 24.
Further, the turntable 24 can support the lower surfaces of the pallets 1A and 1C without the traversing pins 21 and the horizontal members 25 interfering with the pallets 1A and 1C.

The lifting device 30 includes, for example, a lifting frame 31, a lifting ball screw 32, a ball nut 33, a synchronous sprocket 34, and a thrust bearing 35.
The elevating frame 31 has a horizontal turning device 22 fixed to an upper portion thereof and is attached to the cage 14 so as to be movable up and down. In this example, ball nuts 33 are fixed to the four corners of the lifting frame 31. Further, four elevating ball screws 32 screwed with the ball nut 33 extend vertically, and lower ends of the ball screws 33 are fixed to the cage central portion 14 c of the cage 14 via thrust bearings 35.
A synchronous sprocket 34 is attached to each lifting ball screw 32, and four lifting ball screws 32 are rotated in synchronization with a chain (not shown) meshing with the same. Further, a drive motor (not shown) for driving the chain or the synchronous sprocket 34 is provided.

With the above-described lifting device 30, the lifting frame 31 can be lifted and lowered with respect to the cage 14 by rotating the four lifting ball screws 32 in synchronization with a drive motor (not shown). Moreover, the raising / lowering position can be correctly set to arbitrary positions by a limit switch or NC control.
Hereinafter, this lift position is defined as three positions: an upper position, a middle position, and a lower position. The elevating device 30 elevates and lowers the horizontal turning device 22 in accordance with the height of the transverse groove 2 of the pallets 1A and 1C.

  The “upper position” by the elevating device 30 is set to a state where the lower surfaces of the pallets 1A and 1C are supported by the turntable 24 of the horizontal turning device 22 and the pallets 1A and 1C are floated from the traverse rail 16. In this state, the pallets 1A and 1C can be horizontally turned on the cage 14 by horizontally turning the turntable 24 by the turning drive device 23.

The “middle position” by the elevating device 30 is the height at which the turntable 24 of the horizontal turning device 22 does not contact the lower surface of the pallets 1A and 1C and the traversing pins 21 are fitted in the traversing grooves 2 of the uneven pallet 1A. Is set to
The “lower position” by the lifting device 30 is such that the turntable 24 of the horizontal turning device 22 does not come into contact with the lower surfaces of the pallets 1A and 1C, and the traversing pins 21 are fitted in the traversing grooves 2 of the new flat pallet 1C. It is set to the height you want.
With this configuration, the pallet 1A, 1C is traversed between the storage shelf 12 by horizontally traversing the traversing pin 21 by horizontally traversing the horizontal member 25 by the pivot driving device 23 at the middle position and the lower position. Can be made.

FIG. 6 is a front view of the cage 14 at the loading / unloading port, where (A) shows an uneven pallet 1A and (B) crosses a new flat pallet 1C.
6A and 6B, the stop height of the lower surface of the stopper 7 provided on the cage suspension 14a of the cage 14 is b1 (for example, 90 mm) from the boarding height H1. The same is true for the flat pallet 1C.

  In FIG. 6A, the horizontal turning device 22 is positioned at the above-mentioned “middle position” by raising and lowering the horizontal turning device 22 according to the height of the traversing groove 2 of the uneven pallet 1A by the lifting device 30. ing. In this state, the turntable 24 of the horizontal turning device 22 does not contact the lower surface of the uneven pallet 1A, and the traversing pins 21 are fitted in the traversing grooves 2 of the uneven pallet 1A. Therefore, in this state, by horizontally swiveling the traversing pin 21 by the horizontal swivel device 22, the uneven pallet 1 </ b> A is horizontally moved along the traversing rail 16 by the engagement of the traversing groove 2 and the traversing pin 21. The concavo-convex pallet 1 </ b> A can be traversed between adjacent storage shelves 12.

  In FIG. 6B, the horizontal turning device 22 is moved to the above-described “lower position” by moving the horizontal turning device 22 up and down in accordance with the height of the transverse groove 2 of the new flat pallet 1 </ b> C by the lifting device 30. doing. In this state, the turntable 24 of the horizontal turning device 22 does not contact the lower surface of the new flat pallet 1C, and the traversing pins 21 are fitted in the traversing grooves 2 of the new flat pallet 1C. Accordingly, in this state, the horizontal swiveling device 22 horizontally swivels the traversing pin 21, and the new flat pallet 1 </ b> C is moved along the traversing rail 16 by the engagement of the traversing groove 2 and the traversing pin 21. The new flat pallet 1 </ b> C can be moved horizontally between the adjacent storage shelves 12.

According to the configuration of the present invention described above, the uneven pallet 1A and the new flat pallet 1C of the present invention have the same height from the upper surface of the traverse rail 16 to the road surface 5 on which the vehicle is placed. When 14 is stopped at the loading / unloading port, the stop height of the stopper 7 provided in the cage hanging portion 14a of the cage 14 is the same for the uneven pallet 1A and the new flat pallet 1C.
Therefore, the stop height of the cage 14 at the loading / unloading port can be made common, thereby reducing the required number of the dog retracting devices 8 required at the loading / unloading port.

On the other hand, the traversing groove 2 of the new flat pallet 1C of the present invention is provided at a position lower than the traversing groove 2 of the uneven pallet 1A so as not to protrude upward from its upper surface. The horizontal turning device 22 is moved up and down in accordance with the height of 2. Accordingly, in both cases of the uneven pallet 1A and the new flat pallet 1C, the horizontal slewing device 22 horizontally swivels the traversing pins 21 engaged with the traversing grooves 2, thereby allowing the pallets 1A and 1C to move to the storage shelf 12. Can be rampant between.
Therefore, depending on the type of pallet (uneven pallet 1A or new flat pallet 1C), the concavo-convex pallet 1A and the new flat pallet 1C can be mixed by simply lifting and lowering the horizontal swivel device 22 by the lifting device 30, and the structure is simplified. And control can be facilitated.

Therefore, even in an intermediate-loading type elevator parking apparatus in which a fixed dog is not provided in the middle of the cage hoistway 11, the uneven pallet 1A and the new flat pallet 1C can be easily mixed.
Further, in the case of a column type elevator parking device, the provision of a new flat pallet 1C for a roadway eliminates the need for installing an elevating floor, thereby reducing the cost and the construction period.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
