Description

Description: TECHNICAL FIELD The present invention relates to an improvement of a horizontal circulation type parking device, and particularly to a measure for increasing transfer efficiency.

(Prior Art) In recent years, due to the soaring land prices and the difficulty in obtaining construction sites, mechanical parking devices installed underground without using ground space in order to make effective use of the site have increased remarkably. And as such a mechanical parking device, for example,
As disclosed in Japanese Unexamined Patent Publication No. 15059, a rectangular pallet on which a vehicle is mounted is composed of two horizontal transfer paths arranged side by side and two vertical transfer paths connecting the two horizontal transfer paths. 2. Description of the Related Art A horizontal circulation type device configured to be able to circulate on a circulation path having a shape is generally well known.

(Problems to be Solved by the Invention) However, in the above-described conventional horizontal circulation type parking apparatus, when a large number of vehicles are parked, the number of pallets transferred on the lateral transfer path naturally increases, and the circulation transfer distance increases. Because of the lengthening, it takes a long time to circulate and transfer the target pallet to the loading / unloading position at the time of loading and unloading, and there is a problem that the transfer efficiency is reduced.

The present invention has been made in view of such a point, and a purpose thereof is to take a target pallet up to a loading / unloading position by taking appropriate means capable of shortening a substantial circulating transfer distance of the pallet. The object is to circulate and transfer in a short time, and to surely improve the transfer efficiency. Another object is to reduce the equipment cost by sharing the vertical transport path.

(Means for Solving the Problems) In order to achieve the above object, a solution of the present invention is to additionally provide a vertical transfer path substantially at the center in the longitudinal direction of the horizontal transfer path, Two independent circulation paths are formed, and an elevating means is provided next to the additional vertical transport path.

Specifically, a plurality of horizontal transfer paths for transferring a pallet on which a vehicle is mounted in a horizontal direction are provided side by side, and first and second vertical transfer paths for transferring a pallet in a vertical direction between the horizontal transfer paths are provided as described above. It is provided so as to intersect with one end and the other end of the lateral transfer path. Further, a third vertical transfer path for transferring the pallets in the vertical direction between the horizontal transfer paths is provided so as to divide each of the horizontal transfer paths into two horizontal transfer paths at a substantially central portion in the longitudinal direction. Also,
The third vertical transfer path is shared by the horizontal transfer path portion on one side of each of the horizontal transfer paths divided by the third vertical transfer path, the first or second vertical transfer path, and the third vertical transfer path. And independently constitute first and second circulation paths. The first and second circulation paths arrange two empty spaces in which pallets do not exist at diagonal positions, thereby enabling vertical transfer of a plurality of pallets. The pallets are circulated by performing the lateral transfer. In addition, an elevating unit is provided adjacent to the third vertical transfer path, and the pallets are moved up and down by the elevating unit to load and unload the vehicle. The first and second circulation paths are individually circulated and used.

(Operation) With the above configuration, in the present invention, the plurality of pallets on which the vehicles are mounted are formed by the third vertical transport path that divides the substantially central portion in the longitudinal direction of the plurality of parallel lateral transport paths into two horizontal transport path portions. On either side of the first and second circulation paths configured by being divided, two empty spaces where no pallets exist are arranged at diagonal positions and circulated by performing vertical transfer and horizontal transfer, The vehicle is moved up and down by a lifting means provided adjacent to the third vertical transfer path so as to enter and leave the vehicle.

Therefore, the lifting / lowering means is located substantially in the middle between the first circulation path and the second circulation path, and the circulating / transporting distances to the two lifting / lowering means are substantially equal. In the case where no vertical transfer path is provided, that is, a circulation path for transferring a pallet in a vertical direction by first and second vertical transfer paths provided so as to intersect one end and the other end of each of the horizontal transfer paths. Is reduced by half compared to the case of
Therefore, the target pallet is circulated and transferred to the loading / unloading position in a short time, and the transfer efficiency is reliably improved.

Further, since the third vertical transfer path is shared as the vertical transfer path of the first and second circulation paths, it is sufficient that there is one vertical transfer means including a driving device or the like for driving the vertical transfer path, Equipment costs are reduced accordingly.

Next, the operation of the parking device configured as described above will be described.

As described above, this parking device uses the first circulation path 15 and the second circulation path 16 individually.
The pallet transfer by the circulation path 15 will be described.

(1) First, as shown in FIG. 1, the intersection of the first horizontal transfer path 2 and the first vertical transfer path 4, the second horizontal transfer path 3 and the third
The pallet 1 is circulated and transferred by forming two empty spaces S, S where the pallet 1 does not exist at the intersection with the vertical transfer path 14, respectively. In other words, the two empty spaces S, S are used to simultaneously perform the lateral transfer in the first and second lateral transfer paths 2, 3 in opposite directions, and the two empty spaces S, S are used to perform the lateral transfer. By repeating the operation of simultaneously performing vertical transports in the opposite directions in the first and third vertical transport paths 4 and 14, as shown in FIG.
Is transported next to the lifting / lowering means 17 and stopped. At this time, the second circulation path 16 is stopped, but the stop position of the pellet 1 in this stopped state is slightly shifted (for example, 60 mm) away from the first circulation path 15 from the position during traveling. . Thus, the couplers 8 of the pallets 1, 1,... Circulating through the first circulation path 15 come into contact with the couplers 8 of the pallets 1, 1 located at the ends of the second circulation path 16. And the traveling of the pallet 1 in the first circulation path 15 is not hindered. In this state, the intersection between the first horizontal transfer path 2 and the third vertical transfer path 14 and the intersection between the second horizontal transfer path 3 and the first vertical transfer path 4 are each free space S. _1, and has a S _1.

(2) Then, the pallets 1, 1,... On the side of the first horizontal transfer path 2 of the first circulation path 15 are slightly moved in a direction away from the second circulation path 16, and the first lateral transfer of the second circulation path 16 is performed. The pallets 1, 1,... On the side of the path 2 are transferred to the first circulation path 15 by one pitch (for one pallet), and as shown in FIG. the intersection portion between the second vertical transfer channel 5 to the empty space S _2. At this time, since the pallets 1, 1,... Of the first circulation path 15 on the side of the first horizontal transfer path 2 are slightly moved away from the second circulation path 16, the pallets 1 And the second circulation path which has been laterally transported.
The contact of the pallets 1 located at the end of the pallet 16 on the side of the first horizontal transfer path 2 with the connectors 8 is avoided.

(3) Thereafter, as shown in FIG.
The pallet 1 located a lateral flow path 3 at an intersection between the second vertical transfer path 5 to the vertical transfer in the free space S _2. Thus, intersection portions of the second lateral transfer passage 3 and the second vertical transfer path 5 becomes empty space S _3.

(4) Thereafter, the second view, as shown in (d), 1 pitch of each pallet 1 of the second lateral flow path 3 side of the second circulation path 16 in the empty space S ₃ side (1 pallet min) Only lateral transfer. Thus, the upper elevator means 17 is vacant space S _4.

(5) Then, as shown in FIG. 2 (e), 1 pitch of each pallet 1 of the second lateral flow path 3 side of the first circulation path 15 in the empty space S ₄ side (1 pallet min) only Transfer horizontally. As a result, the target pallet 1 is moved up and down
It is transferred onto the movable rails 6a, 6a above the 17.

(6) Thereafter, the elevating means 17 is operated to elevate and lower, and the target pallet 1 is moved up and down to enter and exit the vehicle. In other words, the empty pallet 1 is moved up and down between the pallet 1 on which the vehicle is loaded and the pallet 1 on which the vehicle is loaded when leaving the warehouse.

When the circulation path is switched from the first circulation path 15 to the second circulation path 16, first, the state shown in FIG.
Is moved by one pitch (one pallet) in the direction away from the second circulation path 16. Next, each pallet 1 on the side of the first horizontal transfer path 2 of the second circulation path 16 is moved by one pitch (one pallet) in a direction approaching the first circulation path 15, whereby the first horizontal transfer path 2 The intersection with the second vertical transfer path 5, the second horizontal transfer path 3 and the third
Empty space S, S at the intersection with the vertical transfer path 14 respectively
Are arranged at diagonal positions, and thereafter, the pallet 1 is circulated and transferred in the second circulation path 16. Thereafter, when the target pallet 1 is transferred onto the movable rails 6a, 6a above the lifting / lowering means 17,
The elevating means 17 is moved up and down to move the pallet 1 up and down so that the vehicle enters and leaves.

As described above, in this embodiment, the two first and second horizontal transfer paths 2, 3 arranged in parallel are divided into two horizontal transfer paths by the third vertical transfer path 14 at a substantially central portion in the longitudinal direction. The first and second circulation paths 15 and 16 are configured, and the first and second circulation paths 15 and 16 are configured.
On either side of the pallet 16, the two empty spaces S, S where the pallet 1 does not exist are arranged at diagonal positions and vertical transfer and horizontal transfer are performed to circulate a plurality of pallets 1, 1,.
The vehicle is moved up and down by the elevating means 17 provided adjacent to the third vertical transfer path 14 so as to enter and exit the vehicle.

Thus, the lifting / lowering means 17 can be positioned almost at the middle between the first circulation path 4 and the second circulation path 5 so that the circulating transfer distances to the lifting / lowering means 17 of the vehicle can be made substantially equal. When the third vertical transfer path 14 is not provided, that is, when the first and second horizontal transfer paths 2 and 3 are provided so as to intersect with one end and the other end of the first and second horizontal transfer paths 2 and 3, respectively.
And the pallet 1 can be shortened by half in the second vertical transfer path 4, 5 as compared with the circulation path for transferring the pallet 1 in the vertical direction, whereby the target pallet 1 is circulated and transferred to the loading / unloading position in a short time. Transfer efficiency can be reliably improved.

Further, since the third vertical transfer path 14 is shared as the vertical transfer paths of the first and second circulation paths 15 and 16, the vertical transfer means 13 including a driving device for driving the vertical transfer path is used. It is only necessary to install one instead of separately installing in the first and second circulation paths 15 and 16, and it is possible to reduce the equipment cost by that much.

(Second Embodiment) FIG. 3 shows a schematic configuration of a horizontal circulation type parking device according to a second embodiment of the present invention.
Are smaller than the pallets 1, 1,... On the side of the second horizontal transfer path 3 by one in the first embodiment, and the other components are the same. The reference numerals are attached and the detailed description is omitted.

Therefore, in the present embodiment, the same operation and effect as those of the first embodiment can be obtained. In addition, in the present embodiment, the number of pallets 1 is smaller by one, so that the first
The operation procedures (2) and (3) of the embodiment can be omitted, and the transfer time of the pallet 1 can be shortened accordingly,
There is a merit that the transfer efficiency can be further improved as compared with the case of the first embodiment.

When the circulation path is switched from the first circulation path 15 to the second circulation path 16, first, the second horizontal transfer path 3 of the first circulation path 15 is switched.
Each pallet 1 on the side of the second horizontal transfer path 3 of the second circulation path 16 is slightly circulated in the first circulation direction after moving the respective pallets 1 on the side of the second circulation path 16 away from the fixed position during transfer. It is moved in the direction approaching the road 15 and returned to the home position during transfer (the state of FIG. 3).

Next, the pallet 1 located at the intersection of the first horizontal transfer path 2 and the third vertical transfer path 14 is vertically transferred to the empty space S, and each coupler 8 of the vertically transferred pallet 1 is moved to the second horizontal transfer path. The pallet 1 on the side of the transfer path 3 is engaged and connected to each connector 8.
As a result, the empty spaces S, S are diagonally formed at the intersection of the first horizontal transfer path 2 and the third vertical transfer path 14 and at the intersection of the second horizontal transfer path 3 and the second vertical transfer path 5, respectively. Placed in the position
Thereafter, the pallet 1 is circulated and transferred in the second circulation path 16.

Thereafter, when the target pallet 1 is transferred onto the movable rails 6a, 6a above the lifting / lowering means 17, the lifting / lowering means 17 is moved up and down, and the target pallet 1 is raised / lowered and the vehicle is loaded / unloaded.

(4) As described above, according to the present invention, the circulation path composed of a plurality of side-by-side horizontal transfer paths and the first and second vertical transfer paths is reduced to two by the third vertical transfer path. Since the first and second circulation paths that can be divided and used independently and independently can be used, and the lifting / lowering means are provided adjacent to the third vertical transfer path,
The circulating distance of each of the first circulation path and the second circulation path can be reduced by half, and the target pallet can be circulated and transferred to the loading / unloading position in a short time, so that the transfer efficiency can be reliably improved.
Further, since the third vertical transfer path is shared as the vertical transfer paths of the first and second circulation paths, the equipment cost can be reduced as compared with the case where dedicated vertical transfer paths are provided in the first and second circulation paths, respectively. Can be achieved.
