Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention consists of a transverse section consisting of storage carts or trays that are arranged movably adjacent to each other in horizontal traveling rows disposed one above the other; This invention relates to a multi-layered box-type circulation parking system in which parking system units are arranged in a superimposed manner, each consisting of a vertical transfer means or an elevating section consisting of a lift.

(Prior art) The above-mentioned two-layer box-type circulation parking device includes:
For example, there is Patent No. 430880 (Special Publication No. 39-7442) "Garage with Elevator", which is shown in Figures 1 and 2.
As shown in the figure, trays 1 on which automobiles are to be placed are arranged adjacently in two rows that exist above and below, and one vertical tray is placed at the beginning and end of each row. Transfer means or lift 2,
3 is installed and drive-coupled with the transverse part,
These transfer means include drive shafts 6, 7 mounted on two posts 4, 5 which operate in a bucket elevator type, and a drive shaft 1 wound endlessly around these shafts.
It is composed of a pair of link chains 8, 9 and movable rails 10, 11 for accommodating the tray 1, which are articulated to these chains, and in this case, the drive shafts 6, 7 are 12,
13 connects the connecting shafts 14, 15 and the turning transmission mechanism 1.
The number of movable rails 10, 11 is preferably the same as the number of existing columns;
A roller 18 attached to the tray 1 rotates on a fixed rail 19 and movable rails 10, 11,
This roller rotation is caused by the motor 20 connecting shaft 21,
This takes place via a right-angle transmission mechanism 22 and a pinion 23.

In addition, in the parking device described above, the circulation drive in the direction of the arrow shown in FIG.
At the same time as the trays 1 to movable rails 11 move upward, the trays 1 to movable rails 10 of the starting end elevating section or lift 2 move downwards, and then the There is one upper tray row connected to each other by the engagement of the connecting fitting 24 and the female connecting fitting 25 having a U-shaped cross section.
This is achieved by a two-step drive system in which the lower tray row moves one pitch to the right at the same time as it moves one pitch to the left.

(Problem to be solved by the invention) In the parking device using the drive method described above, the limit of the number of cars that can be accommodated is determined by the machine operating speed in relation to the retrieval time. If the layout becomes
The drawback is that it is difficult to use because it takes a long time to enter and exit the warehouse.

(Means for solving the problem) Therefore, according to the present invention, adjacent to one side of the tray loading/unloading lift that reaches the boarding level installed on the underground floor, there is a sequential front parking unit, an intermediate lift, and a rear parking unit. The side parking device unit and the end lift are installed so as to be drivingly connected to each other, and the level of the plurality of tray rows of the rear parking device unit is set to be lower than the level of the plurality of tray rows of the front parking device unit so that the coupler engages or disengages. In addition to increasing the height by the distance, the intermediate lift and end lift are also set to a height corresponding to the distance.

(Example) In FIG. 3 (two underground levels) showing the multi-layer box-type circulation parking system according to the present invention, the same parts as the conventional system shown in FIGS. 1 and 2 are given the same reference numerals. Basically, there is a tray loading/unloading lift 31 installed on the underground floor 30 that reaches the boarding level GL, a front parking device unit U ₁ , an intermediate lift 32, a rear parking device unit U ₂ , and an end lift 33. In other words, there is an intermediate lift 32 located in the center of the horizontal portion forming the upper row and lower row consisting of a large number of trays 1, which can also serve as a circulating operation for both of the parking device units. This is what was installed.

That is, the tray loading/unloading lift 31 mainly includes a lower drive shaft 36 driven by a motor 35 provided at the base of the gate-shaped post 34, a driven shaft 37 provided on the upper surface of the post, and a drive shaft 37 provided on the top surface of the post, and a drive shaft 37 that is connected to these shafts as appropriate. A pair of endless chains 38 and tray 1 are mounted via sprocket wheels (not shown).
The parking system units U ₁ and U ₂ are arranged vertically in horizontal traveling rows, as shown in FIGS. The traversing device (motor 20, connecting shaft 21, right-angle transmission mechanism 22, and pinion 23) shown in FIG. It consists of a car loading tray 1, an intermediate lift 32 and an end lift 33.
is of similar construction to the vertical transfer means or lifts 2, 3 shown in FIGS. 1 and 2.

Here, in order to shorten the entry/exit time in a parking device that accommodates a large number of parking devices, parking device units U ₁ and U _{2 are}
It is necessary to perform circulating operation for each separately and independently. Therefore, it is necessary to disengage the male connecting fitting 24 and female connecting fitting 25 shown in Fig. 2 at the intermediate lift 32. Therefore, the level of the plurality of tray rows of the parking device unit U ₂ is made higher than the level of the plurality of tray rows of the parking device unit U ₁ by the engaging or disengaging distance S of the coupler, and accordingly, the intermediate lift 32 and the end The height of the section lift 33 is also set to a height that can correspond to the distance S.

(Function) As shown in FIG. 3, when the tray 1 is placed on the movable rail 10 of the intermediate lift 32, the circulation drive of the front parking device unit _U1 is as described for the conventional device shown in FIG. As shown above, tray lifting and tray horizontal movement are performed independently and separately in two steps in the directions of the arrows, and in the case of a conventional parking device that accommodates a large number of vehicles, it is carried out at the back side far from the entrance. When calling the tray 1, the circulation operation was not possible while the tray was operating on the loading/unloading lift 31 and during loading/unloading time at the entrance, but the tray 1 on the movable rail 10 of the intermediate lift 32 was Raise it to the position, remove the coupler, and connect the coupler with the upper tray 1 of the parking device unit _U2 .
The parking device unit _U2 on the back side can be independently operated in circulation.

(Effects of the invention) As described above, according to the invention, the intermediate lift 32 is installed in the center of the transverse part of the multi-vehicle parking system, and the front side and back side parking system units U ₁ ,
Since the parking system is divided into ₂ parts and both parking equipment units can be operated independently, circulating operation is possible by circulating the rear tray, which can shorten the parking time. It is.

In the above embodiment, a parking device with two underground levels was described, but it goes without saying that the present invention can be applied to a parking device with at least six levels.
