Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intermediate parking elevator type parking apparatus and a method for loading and unloading a vehicle.

[0002]

2. Description of the Related Art Generally, a parking device of this type is required to accommodate a large number of automobiles in a narrow space, and at the same time, it is required to shorten the processing time required for loading and unloading automobiles. Further, in order to realize a front entrance and a front advance warehouse to easily carry out an entering and exiting operation of an automobile, a device in which a turntable that is a rotating device is installed on a car entrance floor of the parking device is widely used. An increase in the number of vehicles that can be accommodated can be dealt with by increasing the number of parking spaces on the ground or underground or both for one site. Although the number of floors of the parking space can be increased, since the turntable is located on the entry / exit floor of the vehicle, it is an obstacle for the elevator device to perform the ascending / descending operation from the floor above the floor to the floor below. Therefore, as a conventional example for solving such a problem, for example, there is one disclosed in Japanese Patent Laid-Open No. 3-208970. This is a parking device having an elevator device that has a carriage that moves up and down in the hoistway of a parking device, and a turntable that turns the vehicle on the loading and unloading floor of an automobile, and the turntable can be retracted to the outside of the hoistway. It is characterized by having done.

As a method of retracting the turntable from the hoistway, the turntable is supported on a lifter installed at the bottom of the hoistway, and the lifter is moved up and down to move the turntable into and out of the vehicle. Examples have been proposed in which the elevator is moved up and down between the floor and the retracted position, or the turntable is supported by a lifter mechanism and a slide mechanism and retracted to the side of the hoistway.

[0004]

However, in the above-mentioned conventional intermediate entry parking system, a rather large mechanism is adopted as a device for advancing and retracting the turntable into the hoistway. Therefore, the cost becomes high. In addition, the elevator device will stop the lifting operation until the turntable advances into the hoistway or until it has been retracted from the hoistway, so the loading and unloading time becomes longer accordingly. There is also the problem of being lost.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a turntable on the floor for loading and unloading vehicles and to transport a vehicle to both upper and lower floors by one elevator. It is an object of the present invention to provide an intermediate parking elevator-type parking device capable of

[0006]

In order to achieve the above object, the present invention provides a hoistway which communicates upwards and downwards from an entry / exit floor of a vehicle, a parking space in which a traverse vehicle is installed, and the hoisting / lowering. It has an elevator device that moves up and down the road and transports the tray, and the tray is inserted into the intermediate loading elevator system parking device that is designed to transfer the tray by the cooperation operation of the elevator device and the traverse carriage. A turntable having a hole formed therein, which is installed in the hoistway of the loading / unloading floor to change the direction of the vehicle, is provided in a tray fitting hole portion of the turntable, and the tray is loaded into the turntable through the tray fitting hole. A tray elevating device for elevating and lowering a certain distance up and down with respect to a surface is provided, and the elevator device includes a turntable and an upper hoistway. The upper lift that lifts up and down and the lower lift that is directly connected to the upper lift at a fixed interval and that moves up and down in the lower hoistway are attached, and the tray lifting device transfers the tray between the upper lift on the upper side of the turntable. The main point is that the trays are delivered to and from the lower lift on the lower side of the turntable.

The parking device may have the same or different number of floors between the upper and lower floors on the basis of the entry / exit floor of the vehicle. In the same case, the parking device may be installed in the upper and lower floors. There is one lower lift, one lift is located at the entry / exit floor of the vehicle, and the other lift is connected at intervals such that it is located at the end of the hoistway. Are different from each other, a plurality of lifts of the elevator apparatus are provided in the hierarchy having the larger number of floors.

In the case where the number of floors is different, when the intermediate lift is located on the entry / exit floor of the vehicle on the side where a plurality of lifts are installed, the lift with the smaller number of floors is located on the endmost floor. When the lift with the smaller number of floors is located on the entry / exit floor of the vehicle, the lift with the largest number of floors is connected at intervals such that it is located on the floor at the end. Further, a relay space is secured in one of the floors through which all of the plurality of lifts provided on the one side pass.

Further, according to another invention of the present application, a hoistway and a parking space formed stepwise along the hoistway, in which the number of floors is different between upper and lower floors based on the entry / exit floor of the vehicle.
It has an elevator device for transporting trays in the hoistway and a turntable for rotating the tray in the hoistway on the loading / unloading floor. The elevator device sandwiches the turntable and hoists in the upper hoistway. The upper lift and the lower lift that goes up and down in the lower hoistway are directly connected to each other, and an elevator apparatus provided with a plurality of lifts is configured in a layer having a large number of layers, and in the layer having a large number of layers, One of the floors through which each of the lifts passes is provided with a relay space for temporarily storing and delivering the tray transported to the endmost direction, and the one with a large number of floors when loading and unloading vehicles. In the hierarchy of, the trays that are transported from the end floor to the entry / exit floor, or from the entry / exit floor to the end floor,
The gist is a method in which one lift transports it to a relay space and temporarily stores it in this relay space, and then the other lift transports it to a target position.

[0010]

According to the present invention, one elevator upper lift is moved up and down only in the upper floor and the lower lift is moved up and down only in the lower floor, so that vehicles of each floor can be loaded and unloaded. Therefore, even if a turntable is installed on the entry / exit floor of the vehicle, only one elevator device is required. In addition, 2 on the hoistway
Since three or three lifts move up and down as a unit, the upper and lower lifts can be selectively used according to the positional relationship between the parking space for the previous loading / unloading work and the parking space for the next loading / unloading preparation work. It is possible to reduce the movement amount for each loading / unloading operation. Further, since the vehicle loading / unloading section is provided with a turntable, it is possible to carry out front entry and exit operations, and even though upper and lower floors are provided, only one elevator device is required, so the cost can be kept low.

Further, even if the number of upper and lower layers is different, it is not necessary to add an elevator device, but simply increase the lift,
Since only one of the plurality of parking spaces needs to be diverted to the relay space, it is economically advantageous that there is no need to take measures such as drastic remodeling of the parking device or addition of equipment.

Further, according to the method of the present invention, in order to load and unload a vehicle located far from the vehicle loading and unloading section, a relay space is utilized, and a tray carried by one lift is moved to this relay space in the middle of lifting. Store temporarily and then continue to transport trays on behalf of another lift. As a result, the vehicle located far from the vehicle loading / unloading section can be brought to the loading / unloading floor efficiently, and the efficiency of the parking device in terms of price increases.

The tray lifting / lowering device 28 lifts / lowers the tray 26 within a certain vertical range centered on the loading / unloading level L of the vehicle, and constitutes a mechanism different from the elevator device 8. Further, the positional relationship among the turntable 14, the tray lifting device 28, and the elevator device 8 is as shown in FIGS. 5 and 6. That is, the turntable 14 takes the position shown in FIG. 5 (hereinafter, referred to as “in / out position”) by the rotating operation when the vehicle is in / out. At this time, the tray 6 is the tray lifting device 2
The vehicle 8 is supported by the vehicle 8 and is installed at the level of the entry / exit level L of the vehicle, and is completely removed from the elevator apparatus 8. On the other hand, the turntable 14 rotates 90 degrees with respect to the previous loading / unloading position when the tray 6 is moved up and down, and takes the position shown in FIG. 6 (hereinafter, referred to as “turning position”). At this time, the tray 26 is in a positional relationship so that it can be supported by the elevator apparatus 8 when viewed in a planar arrangement, and the elevator apparatus 8 and the tray lifting device 28 are inside the elevator apparatus 8 when viewed in a planar arrangement. The tray elevating devices 28 are arranged so as to come to the position of, and do not interfere with each other. Therefore, the tray 26 can be transferred between the elevator device 8 and the tray elevating device 28 by combining the elevating operations of both devices. Each parking space 7 is provided with a traverse carriage 44 for transferring the tray 26 to and from the elevator lift 10, a drive device for the traverse carriage 44, and the like.

Next, an example of the vehicle loading / unloading operation of the parking device 1 according to the above embodiment will be described. 1 to 4 are diagrams for explaining the operation when the vehicle 45 is unloaded from the parking space 7a on the top floor, that is, the tenth floor above the ground. In this case, first, as shown in FIG. 1, the three elevator lifts 10 are lifted and lowered by the operation of the lifting drive device 9, and
The upper lift 10a in the parking space 7a on the 10th floor above the ground
Reach level and stop. On the other hand, in the parking space 7a on the 10th floor above the ground, the tray 26 on which the automobile 45 is placed is pulled out to the ground hoistway 6a together with the transverse carriage 44, and is put on standby. The operation of pulling out the tray 26 and the automobile 45 and the standby operation may be performed before or simultaneously with the lifting operation of the elevator lift 10. And
When the three elevator lifts 10 are lifted again by the lifting device 9, the first upper lift 10a receives the tray 26 as if lifting it from below.

After that, the traverse vehicle 44 is retracted to the parking space 7a in which the tray 26 is pulled out first, and the elevator lift 10 is lowered, so that the tray 26 and the automobile 45 can be lowered, but the elevator lift 10 is lowered as it is. Continuing, the second upper lift 1
0b reaches the entry / exit floor 2 and collides with the turntable 14. Therefore, the elevator lift 10 is lowered and stopped until the first upper lift 10a reaches the sixth floor above the ground (at this time, the second upper lift 10b has not yet reached the loading / unloading floor 2), and at this stage Then, the transverse carriage 44 is pulled out from the relay space 7c on the fifth floor above the ground to the ground hoistway 6a, and the loaded tray 26 and automobile 45 are delivered to the transverse carriage 44. Then, the traverse vehicle 44 is retracted into the relay space 7c, thereby completing the first stage of the vehicle unloading operation shown in FIGS. 1 and 2.

Next, the second stage of the vehicle unloading operation will be described with reference to FIGS. As mentioned above, the traverse truck 4
4 is retracted into the relay space 7c, and then the three elevator lifts 10 are lifted again to move the second upper lift 10b.
To reach the level of the relay space 7c on the fifth floor above the ground and stop it. On the other hand, in the relay space 7c on the fifth floor above the ground, the tray 26 carried in earlier is pulled out to the ground hoistway 6a together with the transverse carriage 44, and is made to stand by. Then, if the three elevator lifts 10 are lifted again by the lifting device 9, this time the second upper lift 10b becomes the tray 26.
Receive and lift. After that, the traverse cart 44 is retracted to the relay space 7c from which the tray 26 is pulled out first, and the elevator lift 10 is lowered, so that the tray 26 and the automobile 45 are lowered.
The upper lift 10b is moved to the vehicle loading / unloading section 3.

The second upper lift 10b that has reached the vehicle loading / unloading section 3 is located before the loading / unloading level L of the vehicle, that is, a position above the loading / unloading level L of the vehicle by a height dimension H1 in FIG. It descends to height position 1), stops, and does not descend below this. Next, the turntable 14 is turned 90 degrees and turned to the turning position (FIG. 6).
Take Then, in the tray elevating device 28, the lever mechanism 33 operates to raise the link member 30 in the guide member 29. As a result, the upper hook 31 attached to the link member 30 reaches the height position 1, and the tray 26
The tray 26 is hit and supported at four points on the lower surface of the tray (see the left side portion of the upper half of FIG. 8). In this way, with the tray lifting device 28 supporting the tray 26, the turntable 14 is rotated 90 degrees to take the loading / unloading position. In this way, when the turntable 14 takes the loading / unloading position, the transfer of the tray 26 is completed, the elevator device 8 is in a free state in which the tray 26 is not loaded, and the elevator device 8 may be stopped at that position or may be on the ground. It is also possible to raise the hoistway 6a.

On the other hand, in the tray elevating / lowering device 28 that has received the tray 26, the lever mechanism 33 is operated after the turntable 14 has reached the loading / unloading position, and the link member 30 is lowered in the guide member 29. As a result, the link member 3
The upper hook 31 attached to 0 moves down to a position (the height position 2) below the loading / unloading level L of the vehicle by the thickness dimension H2 of the tray 26, and then stops. By lowering the tray 26 to this position, the upper surface of the table plate 17 of the turntable 14 and the upper surface of the tray 26 coincide with the loading / unloading level L of the vehicle (see the right portion of the upper half of FIG. 8). Therefore, the automobile 45 placed on the tray 26 can be moved forward from the automobile loading / unloading section 3. After this, the empty tray 26 is transferred to the elevator apparatus 8 by the operation in the procedure opposite to the above, and the original parking space 7a on the 10th floor above the ground
Alternatively, the tray 26 may be placed in the vehicle loading / unloading section 3 while being supported by the tray lifting / lowering device 28, and may be put on standby in preparation for the loading of a new vehicle 45.

Next, the operation for storing the vehicle in the lower floor 5 of the parking device 1 will be described. In this case, the empty tray 26 is supported by the lower hook 32 of the tray lifting device 28, the lower hook reaches the height position 2 by the operation of the lever mechanism 33, and is made to stand by at that position (lower half of FIG. 8). See the left side of the). At this time, the turntable 14 is in the loading / unloading position. In this state, when the automobile 45 enters the automobile loading / unloading section 3 forward and is placed on the tray 26, the turntable 14 is swung 90 degrees to take the turning position (FIG. 6). At the next stage, the elevator device 8 starts to operate, and the three elevator lifts 10 are lifted, and the lower lift 10c is moved to near the lower side of the vehicle loading / unloading section 3. The lower lift 10c that has reached the lower side of the vehicle loading / unloading section 3 rises from the loading / unloading level L of the vehicle to a position (height position 3) below by a height dimension H3, and then stops. It does not rise higher. Next, in the tray lifting / lowering device 28, the lever mechanism 33 slowly operates to gently lower the link member 30 in the guide member 29. As a result, the lower hook 32 attached to the link member 30 descends to the height position 3 while supporting the automobile 45 and the tray 26, and further passes through the height position 3 and moves downward. Then, the lower lift 10c of the elevator device 8 hits the lower surface of the tray 26 at four points and supports the tray 26 (see the right side portion of the lower half of FIG. 8). This completes the transfer of the tray 26 from the tray lifting device 28 to the elevator device 8. The lower hook 32 of the tray elevating device 28 continues to descend after the tray 26 is passed to the elevator device 8 in accordance with the descending motion of the link member 30, and moves outward from the tray fitting hole 27 along the backward trajectory of the guide member 29. Be drawn in.

Next, the elevator device 8 starts to operate again, this time the three elevator lifts 10 are lowered, and the lower lift 10c on which the tray 26 and the automobile 45 are loaded.
Is moved to the lower floor of the target underground parking space 7b. At this time, the tray lifting device 2 is inserted into the tray fitting hole 27.
Since the lower hook 32 of 8 does not project, there is no concern that the body of the automobile 45 descending the underground hoistway 6b will be caught by the lower hook and damaged. Then, the elevator device 8 that has reached the target floor by the lower lift 10c delivers the tray 26 and the automobile 45 to the transverse carriage 44, and stores them in the underground parking space 7b by the transverse carriage 44. The elevator device 8 that has passed the tray 26 and the automobile 45 to the transverse carriage 44 is in a free state in which the tray 26 is not loaded, and may be stopped at that position, or may be moved up and down the underground hoistway 6b. Will also be possible. Further, the turntable 14 may also be kept in the current turning position, or the elevator device 8
It is also possible to take the empty tray 26 carried by the customer and rotate it to take the loading / unloading position.

As described above, according to the present invention,
In a parking device having a plurality of floors above and below ground and a turntable at a vehicle loading / unloading level in the middle of a hoistway, a plurality of lifts are connected to an elevator device at predetermined intervals, It is not necessary to provide separate elevator devices above and below the ground because the tray lifting device is provided on the turntable as well as the lifting and lowering motion is performed separately in the basement. In addition, by separately using the upper and lower lifts according to the positional relationship with the parking space in which the previous loading / unloading work is performed, it is possible to reduce the amount of movement of the entire elevator device each time the loading / unloading work is performed, and the entire device is simple. It is possible to increase the accommodation capacity of an automobile and shorten the time required for loading and unloading while securing safety while ensuring low cost in the structure.

Further, even if the number of upper and lower floors is different, it can be dealt with by adding a lift and securing a relay space without adding an elevator device. Therefore, a large modification of the parking device or a fundamental review of the design is required. It is economically advantageous because it does not require major changes and does not require additional equipment or equipment.

Further, since the elevator device has a plurality of lifts, the amount of movement of the elevator device is reduced, so that the height of the entire device or the lower pit can be reduced. Furthermore, when a vehicle is loaded and unloaded by one lift, the other lifts can be in a position to wait for loading and unloading of the vehicle in a position corresponding to the next lift at a position distant from the loading and unloading floor of the vehicle. It is possible to shorten the time required to reach the target layer when the delivery operation of the vehicle is started, and it is possible to quickly perform the loading / unloading operation of the vehicle.

Further, according to the method of the present invention, in order to carry out the loading and unloading of the vehicles on both the upper and lower floors with one elevator device without the lift colliding with the turntable, the relay space is utilized and one The tray carried by the lift is temporarily stored in the relay space while moving up and down, and then
Since we have devised a method to continue transporting trays instead of another lift, trays farthest from the loading and unloading floor of the vehicle can be brought to the loading and unloading floor with ease, and the price of parking equipment can be kept low. Further, various effects can be obtained, such as being able to sufficiently cope with the demand for function integration such as equipment of turntables or high-rise parking devices.
