Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a multi-level circulation parking system.

(Prior Art) In general, in a multi-layer circulation parking system, in order to support and circulate a plurality of pallets to be mounted on vehicles, a plurality of lateral transfer paths, each equipped with a transfer rail, are spaced vertically in a multi-layer parking system. At the same time, two vertical transfer paths are provided to connect one end of each horizontal transfer path and the other end to transfer the pallet up and down. A parking section in which pallets are circulated is constituted by the road and the road. In this case, a vehicle loading/unloading section is provided above the parking section, and one of the above two vertical transfer paths is extended upward for use in lifting and lowering pallets to connect the parking section and the loading/unloading section. It is usually considered to be a lift.

Furthermore, it is generally known that in a parking device, a pallet turning means is provided in order to smoothly load a vehicle onto the pallet at the loading/unloading section and unload the vehicle from the pallet. That is, for example,
Publication No. 5539 discloses a system in which a turntable is provided in the loading/unloading section, and a pallet is inserted into the pallet insertion opening provided in the center of the turntable, and the vehicle is turned 180 degrees to change the direction of the vehicle. Are listed. According to this, even if the vehicle is placed on a pallet while being moved forward when entering the warehouse, it is possible to unload the vehicle from the pallet while moving the vehicle forward when leaving the warehouse.

(Problem to be Solved by the Invention) Incidentally, the above-mentioned vehicle loading/unloading section is often provided on the first floor of a building facing the road, but generally the area adjacent to the loading/unloading section on the first floor is a store. It is usually used for highly profitable purposes such as However, in the above-mentioned conventional technology, if an entry/exit section is provided on the first floor,
A large space must be secured there for vehicles to turn around, and even if this first floor is to be used for profitable purposes, there is a problem in that the usable space becomes narrow. Furthermore, the method of turning the vehicle by fitting the pallet into the turntable requires a large turntable, and such turning means increases the manufacturing cost of the parking equipment.

(Means for Solving the Problems) The present invention solves these problems by providing a system in which the direction of the vehicle is changed at the parking section where the vehicle is accommodated, instead of at the loading/unloading section. This eliminates the need for a large space in the loading and unloading section, and by locating the pallet turning position on the horizontal transfer path in the parking section and next to the lift, there is no extra space in the parking section for turning. This eliminates the need to take up a lot of space.

In other words, the concrete means for this purpose are a plurality of lateral transfer paths provided vertically at intervals so that a plurality of pallets to be mounted on a vehicle are supported on transfer rails for lateral transfer, and a plurality of lateral transfer paths provided at intervals vertically, A multi-layered circulation system comprising a lift having a pallet support rail connectable to the transfer rail of each of the horizontal transfer paths, and a plurality of vertical transfer paths for vertically transferring pallets between each end of the plurality of horizontal transfer paths. The parking apparatus is characterized in that a turning means for receiving a pallet from the horizontal transfer path and rotating it around a vertical axis is provided at a position adjacent to the lift on the horizontal transfer path.

(Function) In the above parking device, even if the vehicle is moved forward and loaded onto an empty pallet in the loading/unloading section, the pallet can be rotated by the turning means in the horizontal transfer path to change the direction of the vehicle. When the vehicle is taken out of the warehouse, the vehicle can be unloaded from the pallet while being moved forward at the entry/exit section.

Since the turning means is a horizontal transfer path and is provided at a position adjacent to the lift, a pallet turning space can be formed by using the pallet hoisting path and the horizontal transfer path by the lift. It is something that can be done.

That is, after the pallet is transferred laterally to the lift side on the horizontal transfer path and the pallet carrying the vehicle to be turned is positioned on the turning means, the pallet on the lift is raised or lowered by this lift, and the pallet is Free space can be created in the hoistway. Next, the pallet to be rotated is left on the rotation means and the other pallets are transferred laterally to the opposite side of the lift, thereby creating an empty space on the opposite side of the lift between the pallets on the rotation means. be able to. In other words, an empty space for one pallet is formed on each side of the pallet to be rotated, and the pallet can be rotated using both of these empty spaces.

(Effects of the Invention) Therefore, according to the present invention, in the multi-layer circulation parking system, since the pallet turning means is provided in the lateral transfer path and at the position adjacent to the lift, there is no need to The pallet can be rotated to change the direction of the vehicle without having to secure a large pallet rotation space, and the efficiency of using limited space can be improved. In addition, since the lift and the turning means are basically independent, when the vehicle to be put into the warehouse is on the width side, the lift is used only for the work of putting the vehicle into the warehouse, and the vehicle is moved only after the work has finished. When vehicles to be taken out are piled up, the lift is used exclusively for the unloading work, thereby increasing the operating efficiency of the lift and making it possible to quickly carry out the work in and out of the warehouse.

(Example) Embodiments of the present invention will be described below based on the drawings.

In the parking apparatus shown in FIG. 1, reference numeral 1 indicates a parking section provided in the basement of a building, and 2 indicates a vehicle entry/exit section provided above the parking section. In the parking section 1, there are pallets 3 for mounting multiple vehicles.
There are two upper and lower layers of lateral transfer paths 4.5 each extending laterally to support and circulate the vehicle. A circulation path is constructed in which the pallets 3 are circulated up and down by communicating with each other by a lift (vertical transfer path) 6 and connecting the other end by an up and down transfer path 7.

Then, the pallet 3 is placed on the floor of the loading and unloading section 2.
The loading/unloading port 8 into which the pallet 3 is inserted is open, and a turning means 9 for turning the pallet 3 is provided at a position of the lower lateral transfer path 5 and adjacent to the lift 6.

First, as shown in FIG. 2, the pallet 3 is equipped with connectors 11a and 11b on both left and right sides of the pallet 3, which connect horizontally adjacent pallets with each other during lateral transfer, and from the four corners of the lower surface, respectively. A total of four wheels 12 are provided that protrude from the front and rear. The coupler 11a is L-shaped and has a vertical plate-shaped engagement part that protrudes in one direction in the vertical direction at the tip of the base that protrudes from the end of the pallet 3 toward the lift 6, and the coupler 11b It has an L-shape having a vertical plate-shaped engagement portion projecting in the other direction in the vertical direction at the tip of the base projecting from the end of the top part 3 toward the vertical transfer path 7 side. That is, the two connectors 11a and 11b connect adjacent pallets by lateral transfer by bringing the inner surfaces of their engaging portions into contact with each other, and also prevent separation and connection due to relative vertical movement of the pallets. There are two things that allow the transition to .

Thus, the pallet 3 is connected to the couplers 11a, 1 on both sides with respect to the center of rotation C of the pallet by the rotation means 9.
1 a, 1 l b, and 11 b are configured to be point symmetrical (that is, in Fig. 2, pallet 3 shown by a solid line and pallet 3 shown by 2 store relocations are arranged so that they are point symmetrical before and after turning, respectively. (indicates the condition).

Each of the upper and lower lateral transfer paths 4 and 5 includes a pair of parallel and laterally extending transfer rails 13.13 for supporting the pallet 3 and guiding its lateral transfer; lateral transfer means 14.

The lift 6 extends from the lower side of the lower lateral transfer path 5 to the above-mentioned entry/exit port 8, and is connected to the transfer rail 1 of each lateral transfer path 4, 5.
A plurality of pallet support rails 15 which can be connected to the pallets 3.13 are provided so as to be movable up and down, and the pallets 3 can be moved up and down between the upper and lower lateral transfer paths 4.5 and the loading/unloading section 2. That is, four pillars 16 are erected in the hoistway of the pallet 3, corresponding to the four corners of the rectangular pallet. Then, two sprockets 18 are attached at intervals to upper and lower horizontal shafts 17.17 installed on two horizontally adjacent columns 16.16, and between the upper and lower corresponding sprockets 18.18. An endless chain 19 is suspended from the top. Therefore, a total of four chains 19 are provided at the front and rear positions of the hoistway, two chains 19 at intervals in the lateral direction.

The plurality of pallet support rails 15 are connected to two laterally adjacent chains 19 and 19 located at the front and rear of the hoistway, respectively, at intervals in the chain longitudinal direction. Pallet support rail 15.1
At 5, the pallet 3 engages the wheels 12 and is supported.

In this case, in order to drive the chain 19, a reducer 2020 is directly connected to the two lower shafts 17, 17, and a drive motor 21 is connected to the transmission shaft 22.
．． They are connected via 22.

The vertical transfer path 7 has four pillars 23 similar to the lift 6 described above.
Since the sprocket 25 is attached to the upper and lower shafts 24 and 24 provided in the
A support rail 27 for supporting the pallet 3 is connected to the pallet 3. The drive mechanism of the chain 26 is the same as that of the lift 6, and its illustration is omitted.

The turning means 9 is located at the lower lateral transfer path 5, and
At a position adjacent to the lift 6, it is supported on the floor of the parking section 1 via elevating means (four jack cylinders) 31. That is, the elevating means 31 includes an elevating base 32.
is supported, and a swivel base 33 for supporting the pallet 3 is supported on the lifting base 32 so as to be rotatable around a vertical axis by a swivel drive means 34. In this case, the lifting means 3
1 is configured such that the pallet 3 can be raised and lowered between the height supported by the transfer rail 13 of the lateral transfer path 5 and the height at which the connection between adjacent pallets 3, 3 is released.

Next, the operation of the parking facility will be explained.

First, in the circulation path, two empty spaces where no pallet 3 is present are arranged in the lift 6 and the vertical transfer path 7 so as to be located diagonally to each other, and the pallet 3 is circulated. That is, the lift 6 and the vertical transfer path 7
The pallet support rails 15.15.27.27 are connected to the transfer rails 13.13 of the upper and lower lateral transfer paths 4.5, and the pallet lateral transfer in opposite directions is carried out toward the two diagonally diagonal empty spaces. The pallet 3 is moved in circulation by repeating the following operations: simultaneously carrying out the above operations, and then raising and lowering the pallet 3 using the lift 6 and the vertical transfer path 7.

Now, when storing a vehicle, the vehicle is supported by the support rails 15 of the lift 6 and loaded onto the empty pallet 3 fitted into the loading/unloading port 8 of the loading/unloading section 2. 15 to the upper or lower horizontal transfer path 4,
5 is connected to the transfer rail 13, and the stored vehicle is transferred to the circulation path together with the pallet 3 by the operation of the traversing means 14.

When changing the direction of a vehicle, the target pallet 3 carrying the vehicle whose direction is to be changed is placed on the turning means 9 in the lower lateral transfer path 5 by the above-mentioned circular transfer of the pallet 3. In this case, there are two pallet support rails 15 connected to the horizontal transfer path 4 above the lift 6 and a pallet support rail 27 connected to the horizontal transfer path 5 below the vertical transfer path 7.
An empty space will be created at the location. and,
Operate the lift 6 to raise it. This allows this lift 6
The pallet 3 located below and connected to the target pallet 3 is disconnected from the target pallet 3 and rises, and an empty space is formed on the lift side of the target pallet 3.

Next, by raising and lowering the elevating means 31 of the turning means 9, the target pallet 3 is picked up from the lower horizontal transfer path 5 onto the rotating platform 33 and raised, and the target pallet 3 and the lower horizontal transfer path 5 are lifted. The connection with the remaining pallet 3 is released. Then, by laterally transferring the remaining pallets 3 in the lower horizontal transfer path 5 to the vertical transfer path 7 side, an empty space is also formed on the opposite side of the lift 6 with the target pallet 3 sandwiched therebetween.

That is, as a result, empty spaces are formed on both sides of the target pallet 3.

Then, by activating the rotation driving means 34 of the rotation means 9 and rotating the rotation table 33 by 180 degrees, the two empty spaces on both sides are used to move the target pallet 3.
To turn a vehicle and change the direction of the vehicle without causing interference with other vehicles.

After that, the remaining pallets 3 on the horizontal transfer path 5 are transferred horizontally by one pallet to the lift 6 side, and the lifting means 3 of the turning means 9
1 to lower the target pallet 3 to the transfer rail 1.
3, the pallet 3 for this purpose and the remaining pallets 3 are connected. Then, by lowering the lift 6, the state before changing the direction of the vehicle, that is,
Empty spaces are formed at two locations: the pallet support rail 15 connected to the horizontal transfer path 4 above the lift 6, and the pallet support rail 27 connected to the horizontal transfer path 5 below the vertical transfer path 7. .

In this case, as mentioned above, the pallet couplers 11a, ll
Since b is provided point symmetrically with respect to the turning center C,
The pallet 3 after the above-mentioned turning is connected to the couplers 11a and 1 that it has.
This means that it can be connected to the pallets 3, 3 on both sides by lb.

When leaving the warehouse, the target pallet 3 carrying the vehicle is transferred from the upper or lower horizontal transfer paths 4, 5 to the support rail 15 of the lift 6 by the above-mentioned circulation transfer. And lift 6
is operated to raise the pallet for this purpose to the loading/unloading section 2. Thereby, the vehicle can be unloaded from the pallet 3 in a forward state.

In the above embodiment, the entry/exit section is provided above the parking section, but the present invention can also be applied to a case where it is provided below the parking section. Of course, the present invention can also be applied to an intermediate direct entry system in which an entry/exit port 8a is provided beside the lateral transfer path and a vehicle is directly loaded onto the pallet 3 of the lateral transfer path through the entry/exit port 8a.

Further, the position where the turning means is provided may be a place adjacent to the lift (vertical transfer path) 6 in the upper horizontal transfer path 4, and
Vertical transfer path 7 in the upper layer or lower layer lateral transfer path 4.5
A location adjacent to is also acceptable. Furthermore, there is no particular need to make the position of the storage entrance correspond to the position of the turning means.

Furthermore, although the above embodiment relates to a parking device with two upper and lower layers, it goes without saying that the present invention can also be used in a parking device with three or more layers.
