Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a mechanical parking device.

(Prior Art) As an example of a mechanical parking device, a plurality of horizontal transfer rails are arranged above and below to support and transfer pallets for mounting on vehicles.
These horizontal transfer rails are connected to each other by two pallet lifting means installed on the outer side of both ends, so that vehicles can be circulated while being mounted on the pallets, and one of the lifting means is used for loading and unloading vehicles. A multi-layer box-type circulation parking device that is used for both circulation and circulation is generally known.

Regarding the above-mentioned multi-layer box-type circulation parking system, we would like to introduce the recent "
With the spread of high-height vehicles (hereinafter referred to as high-height vehicles) called "high-roof vehicles", regular low-height vehicles (hereinafter referred to as "high-height vehicles") have become popular.
A vehicle capable of parking both low vehicles (referred to as low vehicles) and high vehicles has been proposed (see Japanese Patent Laid-Open Publication No. 63-280157). This product has horizontal transfer rails in three levels: upper, middle, and lower, and a lifting means for loading and unloading and circulation is placed on the opposite side of the horizontal transfer rails in between, and is the same as the upper and lower horizontal transfer rails. An upper parking platform and a lower parking platform are provided, and the horizontal transfer rail accommodates low vehicles, while the upper and lower column platforms accommodate tall vehicles.

(Problem to be Solved by the Invention) However, in the case of the parking device proposed above, even if three levels of lateral transfer rails for low vehicles are provided on one side of the elevating means for both loading and unloading and circulation, two lateral transfer rails are provided on the opposite side. There is only enough parking space available. Even if a tall vehicle is accommodated in the lower parking platform, a large wasted space is created between the tall vehicle and the upper parking platform above it.

That is, an object of the present invention is to configure a parking device in such a way that the above-mentioned wasted space is not created as much as possible when parking sections are provided on both sides of the elevating means for both loading and unloading and circulation.

(Means for Solving the Problems) In order to solve these problems, the present invention focuses on the fact that the pallet support heights of the parking sections on both sides of the loading/unloading/circulating lifting means do not necessarily have to be the same. However, by making the pallet support heights of the two parking sections different so that the pallet elevating platform of the elevating means can be stopped at the pallet support height of each parking section, wasted space is avoided as much as possible. It is something to do.

That is, the means for this purpose includes a pallet circulation path incorporating a lateral transfer rail for supporting and lateral transfer of pallets to be mounted on multiple vehicles, and a pallet circulation path incorporating a lateral transfer rail for supporting and lateral transfer of pallets to be loaded on a plurality of vehicles. a first parking section for accommodating the pallets in a state in which the pallets are stored; and a support rail that is disposed on the side of the pallet circulation path at a predetermined distance from the horizontal transfer rail and that supports the pallets at a different height from the horizontal transfer rail. a second parking section that accommodates vehicles mounted on pallets on the support rail; and a pallet that supports the pallet and is provided between the horizontal transfer rail of the first parking section and the support rail of the second parking section. As well as raising and lowering the support member, the pallet support height position by the loading/unloading section provided above or below both parking sections, the horizontal transfer rail of the first parking section, and the pallet support height by the support rail of the second parking section. and a first pallet for transferring a pallet between the horizontal transfer rail of the first parking section and the pallet support member stopped at a height position where the pallet is supported by the horizontal transfer rail. a second pallet transfer means for transferring a pallet between a support rail of the second parking section and the pallet support member stopped at a height position where the pallet is supported by the support rail; This is a mechanical parking device that is characterized by:

(Function) In the above parking device, since the horizontal transfer rail of the first parking section and the support rail of the second parking section have different pallet support heights, the rail with the lower pallet support height is It is possible to accommodate a lower vehicle on the rail with a higher pallet support height. Since the pallet support member of the elevating means can be selectively stopped at the pallet support height provided by the rails of each parking section, there is no problem in entering and exiting vehicles in both parking sections.

In other words, if a space is secured in one parking section to lower the pallet support height of that rail, the upper end height of the vehicle accommodation space by each rail in both parking sections will be the same, and the height of the vehicle storage space will be the same for low and high vehicles. This means that the vehicle can be accommodated, and no wasted space is created above the vehicle accommodation space.

Therefore, even when a plurality of rails are provided in each parking section, there is no need to provide an extra wide interval between the upper and lower rails.

(Effects of the Invention) Therefore, according to the present invention, the pallet support heights of the rails of the parking section on both sides of the lifting means are made different,
Since the elevating platform of the elevating means can be stopped at the pallet support height of each parking section, two types of vehicles, high and low, can be parked without wasting space.
