Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation parking device that parks a vehicle by circulating a large number of vehicle mounting cages in a vertical direction.

(Prior Art) Generally, such a vertical circulation parking apparatus is configured by suspending a large number of vehicle-mounted cages in a chain form on an endless chain that circulates in the vertical direction. In addition, the cage includes a horizontal pallet and a pair of front and rear inverted U-shaped hangers that support the front and rear portions of the pallet. The pallet and the hanger can be attached and detached except when they are fixed to each other. In some cases, they can be connected together (see Japanese Patent Laid-Open No. 61-75172). This is because the lifter device with a turntable provided at the bottom of the cage circulation path lifts the pallet while the vehicle is still mounted on the pallet so that the pallet can be turned, so that the pallet can always be delivered in forward operation.

(Problems to be solved by the invention) By the way, in the above-mentioned conventional vertical circulation type parking apparatus, the vehicle at the time of entry / exit is installed inside the hanger regardless of whether the pallet and the hanger of the cage are fixed or removable. Although the driver has to pass through, if the driver is inexperienced, there is a risk that the hanger may come into contact with the door mirror or the side part of the vehicle body. In order to prevent such contact, the lateral width of the cage is set to be somewhat larger than the vehicle width.
If the lateral width of the cage is made too large, there are problems such as an increase in the size and cost of the parking device.

The present invention has been made in view of the above points, and an object thereof is to make it possible to enter and leave without passing through the inside of the hanger of the cage as described above, and to prevent a contact accident with the hanger. This is to prevent it in advance.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the invention according to claim (1)
Is a vertical circulation parking device, in which a number of vehicle-mounted cages are suspended in a chain in an endless chain that circulates in the vertical direction, and the cage has a pair of inverted U-shaped front and rear portions of a pallet. It is assumed that it is configured to be supported by a hanger. Then, while the pallet of the cage is placed and engaged with the lower part of the hanger so that it can be pulled out upward,

In particular, in the case where two kinds of cages for vehicles with different heights are mixed as a cage for mounting on a vehicle, in addition to the configuration of the above (1) or (2), the height of the boarding floor can be changed by the cage circulation. The lifter device is installed so that it can be moved up to the pallet position of the low vehicle cage whose table is located at the bottom of the cage circulation route, while the lifter device is set corresponding to the high vehicle cage located at the bottom of the route. The configuration is as follows.

(Operation) With the above configuration, in the vertical circulation parking apparatus according to claim (1), the pallet of the cage located at the bottom of the cage circulation path is lifted from below by the lifter apparatus at the time of loading / unloading. Then, the engagement between the pallet and the hanger is released. After that, the hanger on the loading / unloading port side is flipped inward by the flip-up means to a substantially horizontal state, whereby the cage can be loaded / unloaded into / from the pallet without passing through the inside of the hanger.

Further, in the vertical circulation type parking device of claim (2), especially when the car is unloaded, after the pallet of the cage is lifted by the lifter device and the coupling between the pallet and the hanger is released as described above, a pair of flip-ups is performed. The front and rear hangers are respectively flipped up inward by the means, and in this state, the table of the lifter device is rotated and the vehicle is directed toward the entrance / exit side, so that the pallets can always be discharged in forward operation.

Further, in the vertical circulation type parking device of claim (3), the lifter device can smoothly carry out the loading and unloading of the vehicle into and from the cages for two types of vehicles. In other words, the height of the boarding floor is set corresponding to the high vehicle cage located at the bottom of the cage circulation path,
When a vehicle is loaded into or unloaded from a high vehicle cage, the lifter device only lifts the pallet to release the engagement between the cage pallet and the hanger, and the lifted pallet is lowered to the loading floor. Vehicles are loaded and unloaded from the pallets in a state where they are flush with each other.

It consists of 31 and.

Next, in order to explain the operation of the above embodiment, a cage for a high vehicle
The high-roof car W1 mounted on 4a has a high car height.
When unloading from the car, the cage 4a that has circulated to the vehicle loading place P stops with its pallet 9 flush with the loading floor surface F, as shown in FIG. In this case, the high-roof vehicle W1 on the pallet 9 of the cage 4a has its back turned to the loading / unloading port side (right side in the figure) in the state of loading on the cage 4a (pallet 9). Then, from such a state, the following operations are sequentially performed.

(1) First, the jacks 22, 22, ... Of the lifter device 21 are extended and the turntable 25 causes the cages to move.
The pallet 9 of 4a is lifted up by a predetermined distance. At this time, the front and rear parts of the pallet 9 and the lower parts of the hangers 8a and 8b are engaged with each other by the receiving plate 12 on the pallet 9 side and the pin 10 on the hanger 8a, 8b side as shown in FIGS. 6 and 7. Separated from each other and released.

As a result, the pair of front and rear hangers 8 whose engagement with the pallet 9 is released as described above
The a and 8b are flipped up inside the cage 4a centering on the penetrating portions to the central members 7a and 7b, respectively, and are held in a substantially horizontal state where they are wrapped with the suspension shaft 6 as shown by phantom lines in FIG. .

(3) Subsequently, in the lifter device 21, the rotation mechanism 24 operates and the turntable 25 turns 180 degrees with the pallet 9 being supported.
In the case of 1, the front part faces the entrance / exit side.

(4) After that, the jack 22 expands and contracts, and the pallet 9 descends to a position flush with the loading floor F. Then, in this state, the driver gets into the high-roof vehicle W1 and exits from the top of the pallet 9 through the loading / unloading port by the forward driving. At this time, since the hangers 8b on the loading / unloading port side are in a state of being flipped up in a substantially horizontal state inside the cage 4a together with the other hangers 8a, a door mirror or the like is not brought into contact with the hangers 8b.

(5) Lifter device 21 after exiting this high-roof vehicle W1
Lifts up the empty pallet 9 again. Also, the actuator 28 of each flip-up means 27 operates in the reverse rotation and

When the hangers 8a and 8b are rotated, the hangers 8a and 8b are respectively attached to the stoppers 1 at the front and rear portions of the pallet 9.
While the lever 30 stops at the position where it hits 1, the lever 30 rotates to the position of the substantially drooping state so as not to hinder the circulation of the cage group.

(6) Next, the jacks 22, 22, of the lifter device 21 are
The turntable 25 and the pallet 9 above it are lowered by the expansion and contraction operation of. During this descent, the pallet 9 is placed in the engagement groove 12a of the receiving plate 12 on the pallet 9 side in the hanger 8a, at a position flush with the vehicle loading floor P, as shown in FIG.
When the pin 10 on the 8b side is engaged, it is supported by the hangers 8a and 8b. On the other hand, the turntable 25 stops at a position slightly lower than the pallet 9 engaged and supported by the hangers 8a and 8b as described above. Due to the above, cages for high vehicles
A series of operations when the high-roof vehicle W1 is unloaded from the 4a ends, and the cages 4a and 4b can be circulated.

When the high-roof vehicle W1 is stored in the high-vehicle cage 4a, the operation sequence (1) is substantially the same as the case of the above-mentioned storage.
~ (6) The high roof vehicle W1 is loaded.

That is, when the empty high vehicle cage 4a is stopped at the vehicle entry location P, first, the lifter device 21 is used to move the cage.
The pallet 9 of 4a is lifted and the pallet 9 and the hanger
The engagement with 8a and 8b is released. Next, after the hanger 8b on the loading / unloading entrance side is flipped up to the inside of the cage 4a by the flipping means 27 to a substantially horizontal state, the pallet 9 is lowered to its original position (a position flush with the loading floor surface F). Then, in this state, the high-roof vehicle W1 gets on the pallet 9 from the entrance / exit side in a forward operation. At that time, as in the case of unloading, it is possible to get on the pallet 9 without passing through the inside of the hanger 8b, so that a contact accident with the hanger 8b does not occur. The operation of the high-roof vehicle W1 after getting on the pallet 9 is exactly the same as the operation (5) / (6) after the high-roof vehicle W1 has left the pallet 9 when leaving the garage.

On the other hand, when the low passenger car W2 mounted on the low vehicle cage 4b exits from the cage 4b, the cage 4b that has cyclically moved to the vehicle entry location P is as shown in FIGS. 1 and 2. Then, the pallet 9 is stopped with the loading / unloading port side facing the back, and the pallet 9 is located at a position higher than the loading floor F (about 40 cm above). Therefore, first, at the lifter position 21, the jacks 22, 22, ... Extend with the maximum stroke to lift the pallet 9 of the cage 4a by the turntable 25, and the pallet 9 and the hangers 8a, 8b. To disengage from.

Then, after the hangers 8a, 8b are flipped up to the inside of the cage 4a by the flip-up means 27, 27, ... to a substantially horizontal state, the turntable 25 of the lifter device 21 keeps supporting the pallet 9 180 By turning once, the front part of the high-roof vehicle W1 is turned to the loading / unloading side. continue,
The jacks 22, 22, ... Of the lifter device 21 extend and contract to lower the pallet 9 to a position flush with the loading floor F,
In this state, the ordinary passenger car W2 exits from the pallet 9.

After that, the jacks 22, 22, ... Of the lifter device 21 again extend with the maximum stroke to lift the empty pallet 9. The subsequent operations are exactly the same as the operations (5) and (6) after the high-roof vehicle W1 exits from the pallet 9.

Incidentally, regarding the operation when the ordinary passenger car W2 enters the low vehicle cage 4b, regarding the operation when the high roof vehicle W1 enters the high vehicle cage 4a described above and the ordinary vehicle W2 from the low vehicle cage 4b. Since it is clear from the operation at the time of leaving the warehouse, its explanation is omitted.

Even when the ordinary passenger car W2 enters and leaves such a low vehicle cage 4b, the hanger 8b on the entrance / exit opening side is provided.
Hangers can be entered and exited without passing through the inside.
Of course, there is no chance of contact with 8b. Further, as the pallet 9 of the cage 4b is lifted and lowered by the lifter device 21, the pallet 9 is loaded and unloaded in the same state as the loading floor surface F in the same manner as when the high roof vehicle W1 is loaded and unloaded into the high vehicle cage 4a. Since it is performed, it can be facilitated and facilitated.

The present invention is not limited to the above-mentioned embodiments, but includes various other modified examples. For example, in the above-described embodiment, the bounce-up means 27 is provided at the vehicle entry place P for each of the hangers 8a, 8b of the cages 4a, 4b, one pair each on the left and right sides. The actuator 28 of the two flip-up means 27 may be used in common, or the flip-up means 2 for each hanger 8a, 8b may be used.
Needless to say, the configuration may be such that seven are provided one by one.

Further, as in the embodiment, when the loading / unloading port is provided on one of the ground walls of the building and the table of the lifter device 21 supporting the pallets 9 of the cages 4a, 4b is not the rotatable turntable 25 as in the embodiment ( In this case, when applying the present invention to either one of the entry and exit is performed in reverse operation, only the hanger 8b on the entry / exit opening side of the pair of front and rear hangers 8a, 8b of the cages 4a, 4b. The flip-up means 27 may be configured so that it can be flipped up.

Further, in the above embodiment, the case where the entrance / exit is provided on one of the ground walls of the building facing the vehicle entry place P has been described, but the entrance and exit are provided separately in different directions of the building. It goes without saying that it can also be applied to cases.

(Effects of the Invention) As described above, according to the vertical circulation parking apparatus of the first aspect of the present invention, when the vehicle enters and leaves the cage, the pallet of the cage and the hanger are engaged with each other. It is released by lifting the pallet by, and the hanger on the entrance / exit side of the cage is flipped up to the position of a substantially horizontal state by the flip-up means, so that it is possible to enter and exit without passing through the inside of the hanger. Therefore, contact with the hanger can be prevented.
