Next, for safety, the outer door 9 is closed and the intermediate door 10 is opened, and then the vehicle storage operation is started. Transfer device 40b
Is moved from the first stop position 13a toward the second stop position, the tray 30b supported on the swivel forks 50b, 50b.
Or a car moves together. As shown in FIG. 6 (a), the tray 30b is first taken out and the cage 20b is waiting as it is. The tray 30b is inserted into the area of the cage 30b through the opening 27b of the cage 20b. The state shown in FIG. 7A and FIG. That is, the transfer device 40b is in the second stop position 13b, and the turning fork 5 of the transfer device 40b is
The tray 30b is in the raised position by 0,50.

Next, a turning operation is performed, but this operation is performed in exactly the same way as the case where the tray 30a is turned using the transfer device 40a described above, and therefore the illustration is omitted.

After the turning operation is completed, the rods 46b, 46b, 46b, 46b of the cylinders 45b, 45b, 45b, 45b of the transfer device 40b are shortened and the turning forks 50b, 50b are lowered, and the tray 30b is also lowered. Passed to 20b and supported. The swivel forks 50b, 50b pass through the space 26b of the cage 20b, further descend, and then retract and stop downward. This operation process corresponds to the process from FIG. 5 (a) to FIG. 5 (a) in the case of the first transfer device 20a, and is an equivalent operation.

The above describes the case of warehousing, but the case of warehousing can also be performed by substantially the reverse procedure. However,
Since the turning operation has been completed at the time of entering the warehouse, the turning operation is not performed at the time of leaving the warehouse.

That is, even when leaving the second parking device unit 2b, the outer door 9 is closed to ensure safety, and the intermediate door 10 is opened to form a passage. The second parking device unit 2b is circulated to call the cage 20b on which the required vehicle is mounted to the loading / unloading floor, and the transfer device 40b is positioned at the second stop position 13b, and the turning forks 50b, 50b are raised. Let
Take from tray 30b with car from cage 20b.
On the other hand, the first parking device unit 2a is circulated to call the empty space 6 in the loading / unloading hierarchy, and if the transfer device 40a is located at the first stop position 13a, this is moved to the retracted position 1
Evacuate to 4. Thus, the transfer device 40b is then moved from the second stop position 13b to move the tray 30b together with the car into the cage.
It is pulled out from 30b and conveyed to the first stop position 13a.

If the outer door 9 is opened and the intermediate door 10 is closed, the exit condition is set. The driver of the car can walk from the entrance / exit 7 to the floor 15
After that, the vehicle on the tray 30b is boarded, and the vehicle rolls out through the vestibular portion 8 in the forward posture and exits. Further, next, the outer door 9 is closed and the intermediate door 10 is opened, and the transfer device 40b carrying the tray 30b of the empty vehicle is moved toward the second stop position 13b. In this process, the tray 30b is moved to the previous cage. Insert in 20b. The turning forks 50b, 50b of the transfer device 40b are lowered, the tray 30b is transferred to the cage 20b and returned, and the turning forks 50b, 50b are further retracted downward, thus completing the operation related to the delivery.

The above describes the warehousing / discharging process for each of the parking device units. What is characteristic of this device is that the two transfer devices are processed in parallel according to the warehousing / leaving request to operate efficiently. There is a point that can be. Although various cases can be assumed as to how to operate the transfer device, an example will be described here.

FIG. 8 (a) is for explaining a case in which the warehousing requests are continuously generated and the warehousing to the second parking device unit 2b and the warehousing to the first parking device unit 2a are alternately performed. 4 is a movement diagram of transfer devices 40a and 40b.

In the figure, the vertical axis indicates the position within the pit 11.
The horizontal axis indicates the time T. The polygonal line shows the position of the transfer device 40a or 40b, of which the solid line is unloaded on the transfer device 40a or 40b, the white double line is the black line when only the tray 30b is loaded. The thick line shows the case where an automobile and a tray 30b are loaded. Further, the two lines with diagonal lines indicate the period during which the warehousing work for the first parking device unit is being performed.

Further, regarding the time T, here, it is assumed that the time required for the transfer device 40a or 40b to move at each point (for example, between 13a and 13b) is one unit time, and the processing time such as warehousing and warehousing at each point. Is assumed to take 3 unit hours. The processing time for warehousing and warehousing at each point includes the circulation of the cage 20a or 20b, the raising / lowering operation and turning of the transfer devices 40a and 40b, the opening and closing of the outer door 9 and the intermediate door 10, the entry and exit of cars and people, etc. Therefore, there are variations in practice, but here, for convenience of explanation, it is assumed that the time is constant. In addition, the time indicates cumulative time in the footnote such as T ₀ to T ₃ , T ₄ ...

In the figure, at time T ₀ , the transfer device 40a without a load is retracted to the retracted position 14, and the transfer device 40b loaded with the tray 30b is waiting at the first stop position 13a.

Here, if it is assumed that the second parking device unit 2b has been requested to enter the garage, the vehicle entering from the warehousing port 7 between T _{0 and} T ₃ is received in the tray 20b. The transfer device 40b with said actual vehicle tray 20b in between the next T ₃ through T ₄ is moved to the second stop position 13b, in between the next T ₄ through T _7, the mixture was allowed to pivot vehicle tray 20b 2 The parking device unit 2b is delivered to and stored in the cage 20b. Here, the transfer device 40b is unloaded, but in the next T _{7 to} T ₁₀ , the empty car cage 30b from the other cage 20b of the second parking device unit 2b is also prepared in preparation for the subsequent storage request. Wait for receipt.

Here, if there is a next request for warehousing to the first parking device unit 2a, the transfer device 40 that is retracted to the retracted position 14
a a T ₃ to feed the first stop position 13a moves in between through T _4. T ₄ accept receipts car tray 30a on the cage 20a in between through T _7, in between the next T ₇ through T _10, delivery receipts tray 30a of the vehicle to the cage 20a again pivoted in the region of the cage 20a Let That, T ₄ through T ₇ while the transfer device 40b in between through T ₁₀ is performed taking work receipts and the tray 30b according to the second parking units 2b, parking transfer device 40a is first a parallel task It is possible to execute the warehousing operation related to the device unit 2a.

Transfer device 40a of the non-load in this way T ₁₀ is in the first stop position 13a, while the transfer device 40b loaded with empty car tray 30b is located at the second stop position 13b, the following T ₁₀
Between T _{11 and} T ₁₁ , they are transferred to the retreat position 14 and the first stop position 13a, respectively, and the work of one cycle is completed. Since the state at T ₁₁ is the same as the state at T ₀ , even if the stocking requests of the same pattern continue one after another, the corresponding processing can be performed in exactly the same manner as described above. In addition, one cycle in this example is between T _{0 and} T ₁₁ , that is, 11 unit time.

Here, in order to compare with this, FIG. 8 (a) shows a movement diagram of the transfer device when the conventional device shown in FIG. 11 is used and the work under the same conditions is performed.

Here, it is assumed that only one transfer device 140 is used, and at time T ₀ , the transfer device 140 is loaded with empty trays 130b and stands by at the first stop position 113a.
Assuming that there is receipts requested here to the second parking device unit 102b, accept receipts car tray 130b on the transfer device 140 in between T ₀ through T _3, which in between the next T ₃ through T ₄ Is moved to the second stop position 113b. Then T ₄ ~ T ₇
After that, the tray 130b of the actual vehicle is swung, and then the tray 130b of the actual vehicle is delivered to the cage 120b of the second parking device unit 102b to finish the warehousing, and the transfer device 140 is unloaded.

Here, next, if there is a storage request to the first parking device unit 102a, since the turning operation by the transfer device 140 is required, the transfer device 140 that has not been loaded first is moved to the T
Forwarding to move to the first stop position 113a in between ₇ through T _8. T
_{Between 8 and} T ₁₁ , the receiving vehicle is directly received in the tray 130a on the cage 120a in the first parking device unit 102a, and the transfer device 140 is rotated between T _{11 and} T ₁₄ to end the storing operation. _{At 14} , the transfer device 140 is unloaded.

Moreover, this in turn assumed to be goods receipt request to the second parking device unit 102b, is necessary to keep receiving the empty car tray 130b as this preparation, the transfer device 140 in between T ₁₄ through T ₁₅ It must be forwarded to the second stop position 113b. Between T _{15 and} T ₁₈ , the transfer device 140 is the tray of the empty car from the cage 120b of the second parking device unit 102b.
And receiving the 130b, and moves to the first stop position 113a in between T ₁₈ through T _19, completes the operation of the thus one cycle. Since the state at T ₁₉ is equal to the state at T _0, it is possible to successively respond to the storage request of the same pattern as described above.

In the conventional device described for comparison, 19 units of time were required for one cycle of work, but as described above, 11 units of time were sufficient in the device of the present invention, and the processing time was shortened. ing.

In addition to the above-described example, other loading / unloading patterns are conceivable, but the processing time can be shortened in any case by operating so that two transfer devices can perform parallel work.

[Second Embodiment] Next, FIG. 9 and FIG. 10 in the case where the double row type vertical circulation parking apparatus 1A with a transfer device is constituted by three rows, that is, three parking apparatus units 2A, 2B and 2C. It will be described with reference to the drawings.

In FIG. 9, the parking device units 2A, 2B, 2C are arranged side by side in a triple row, and the parking device units 2A, 2B other than the farthest parking device unit 2C are respectively provided with 1
Blank areas 6A or 6B are formed. A pit 11A is dug through the lower part of these parking device units 2A, 2B, 2C and rails 12A, 12A are laid.
1A and rails 12A, 12A are further extended to the lower part of the front yard 8A,
The retracted position 14A is formed. It also has two transfer devices 40A and 40B rolling along the rails 12A and 12A. In the figure, the transfer device 40A is shown in a first stop position 13A, the transfer device 40B is shown in a third stop position 13C, and each transfer device 40A, 40B is shown schematically, but the configuration is It is equivalent to FIG. 3 (A) and (A) of the above embodiment.

FIG. 10 is a diagram showing a movable range of these transfer devices 40A and 40B, and each movable range is within a hatched range. That is, the transfer device 40A can move from the retracted position 14A to the second stop position 13B via the first stop position 13A. Further, the transfer device 40B is movable between the first stop position 13A, the second stop position 13B, and the third stop position 13C.

In such a configuration, the first parking device unit 2A
If the transfer device 40A is used to perform processing such as warehousing, warehousing, and turning related to the transfer device 40B, the transfer device 40B performs the next warehousing / unloading preparation work relating to the second or third parking device unit 2B or 2C. be able to. Next, if the transfer device 40B is used to perform processing such as loading and unloading, turning, etc. relating to the third parking device unit 2C, the transfer device 40 that has been evacuated.
Early A or second parking device unit 2A using A
Or you can move to 2B loading / unloading work.

Processing such as warehousing, warehousing, and turning related to the second parking device unit 2B can be executed using either of the transfer devices 40A and 40B, but in this case, the next warehousing and unloading work scheduled is Which of the parking device units 2A or 2C is to be used is selected. That is, when the next storage / receipt schedule relates to the third parking device unit 2C, the current work is performed using the transfer device 40A, and the transfer device 40B prepares for the next storage / receipt. Alternatively, if the next loading / unloading schedule relates to the first parking device unit 2A, this work is performed using the transfer device 40B, and the transfer device 40A is evacuated to the retreat position 14A for the next loading / unloading. Make them stand by so that they can respond promptly.

[Effect of device]

The double-row vertical circulation parking system is often adopted because it effectively uses an elongated land, and the device with the transfer system does not require a person to reach deep inside the machinery and equipment. Therefore, it is a preferable device in terms of comfort of use and safety. However, in such a conventional device, one transfer device performs the entire loading and unloading of goods, and therefore, while the transfer device is operating for one work, if this is not completed, the next loading or unloading or preparatory work is performed. Therefore, there is a problem that the waiting time for the customers entering and leaving the warehouse becomes long, and the operating efficiency of the parking facility is reduced.

In the device of the present invention, two transfer devices are used, and the evacuation space for one of the transfer devices is provided, so that while one transfer device is in operation, the other transfer device is moved in and out as a parallel operation. Alternatively, preparatory work can be performed, or the work can be waited for immediately. Therefore, the processing time for loading and unloading can be shortened and the operating efficiency of the apparatus can be improved.
