Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a horizontal circulation parking device.

(Prior Art) As a parking device, a plurality of pallets for mounting a vehicle are provided by two horizontal transfer paths that are arranged in parallel with each other and two vertical transfer paths that connect the both horizontal transfer paths between both ends thereof. A horizontal circulation type that is configured to circulate in a rectangular shape is generally known (see Japanese Patent Laid-Open No. 45-32568). In this case, the horizontal transfer path is provided with a pair of parallel horizontal transfer rails for supporting the pallet, and the pallet is transferred using the horizontal transfer rails as guides. Further, in the vertical transfer path, as shown in FIG. 5, a pair of moving rails c and d are provided on an endless conveyor chain b suspended on a pair of sprockets a and a.
4 sets of pallets are arranged, the pallet e is supported by the moving rails c and d of 2 sets, and the pallet e is transferred between the two lateral transfer paths by the traveling of the conveyor chain b. Is normal.

That is, the distance between the pair of moving rails c and d corresponds to the distance W between the pair of horizontal transfer rails in the horizontal transfer path. By moving the conveyor chain b, one set of moving rails c and d in the vertical transfer path are connected to the horizontal transfer rail to transfer the pallet e between the two transfer paths.

By the way, the circulating transfer of the pallets in the horizontal circulating parking apparatus is performed by forming an empty space at either end of the vertical transfer path. That is, the pallet e can be transferred along the horizontal transfer path by feeding the pallet e into the empty space through the horizontal transfer path. Therefore, an empty space is formed by moving the pair of moving rails c and d located on the carrier side of the conveyor chain b from the state in which they are connected to one horizontal transfer rail to the state in which they are connected to the other horizontal transfer rail. At this time, the pair of moving rails c and d located on the return side of the conveyor chain b must be stopped in the empty space at a position where they are connected to the one lateral transfer rail.

In this case, in order to enable the pallet e to be circulated and moved using the above-mentioned vacant space, the distance between adjacent pairs of moving rails is set so that the adjacent horizontal transfer paths are parallel to each other. All must be constant to accommodate the spacing S between the rails. Therefore, the total length of the conveyor chain b is 4 × (W + S) because four sets of moving rails c and d are arranged at intervals S, that is, the transfer stroke (W + S of the pallet to be transferred in the vertical transfer path). ) Is four times as long.

(Problems to be solved by the invention) However, when the distance S between the adjacent lateral transfer rails between the two lateral transfer paths arranged side by side is wide, the protrusion amount of the sprocket a from the lateral transfer rails (lateral From the moving rail d stopped at the connecting position to the transfer rail to the sprocket a
Distance L) becomes larger. That is, in order to tension the conveyor chain b between the moving rails c and d located at the ends of the carrier side and the return side, the sprocket a must be largely projected from the moving rail at the connecting position. I won't.

In this case, a simple calculation results in the protrusion amount L = 1/2 · S.

Then, as described above, the large protrusion amount L means that when the pair of moving rails c and d support both ends of the pallet e, the sprocket is more sprocket than the stop position of the pallet e in the vertical transfer path. This means that a projects to the outside greatly, and an extra space that does not contribute to parking must be taken. In particular, even if a rectangular parking space is secured in the building to install a horizontal circulation parking device, the pillars of the building often project from the wall at the corners of this space. The sprocket a to be positioned and the column are likely to interfere with each other. Therefore, in order to avoid this interference, the horizontal transfer rails can actually be arranged only inside the pillars, and the utilization efficiency of the parking space is low.

That is, an object of the present invention is to reduce the above-mentioned protrusion amount L so that the drive portion of the vertical transfer path can be contained within the range of the movement path of the pallet as much as possible, and the utilization efficiency of the parking space for housing the vehicle. Is to be able to increase.

(Means for Solving the Problem) In order to solve such a problem, the present invention provides a method in which two moving rails are used as one set and a plurality of sets are arranged on a conveyor chain. By making the gap wider than the rail gap in one set of moving rails, 3
A set of moving rails enables vertical transfer of pallets.

That is, the concrete means for this purpose is to provide two lateral transfer rails, which are provided in parallel with each other and each of which includes a pair of parallel laterally extending lateral transfer rails for supporting a pallet for mounting a vehicle and guiding the transfer thereof. A transfer path, an endless conveyor chain which is disposed between the outer sides of the ends of both the horizontal transfer paths so as to be able to travel in the vertical direction orthogonal to the horizontal transfer rail, and on the conveyor chain along the running direction. And a plurality of moving rails each extending in parallel with the lateral transfer rail, each supporting a pallet by a set of two moving rails with a fixed rail interval, and by moving a conveyor chain, both A rectangular horizontal circulation path for circulating the pallet is formed by the two vertical transfer paths for transferring the pallet between the ends of the horizontal transfer path. A horizontal circulating parking apparatus in which a pair of moving rails of a vertical transfer path are positioned on an extension of the horizontal transfer path to transfer a pallet between the two transfer paths. The chain has three sets of moving rails each having a rail interval shorter than the length of the pallet in the vertical transfer direction, with a constant interval wider than the rail intervals between adjacent sets of moving rails. It is a horizontal circulation type parking device characterized in that it is arranged at a pitch longer than the length of the pallet in the vertical transfer direction.

In this case, the rail spacing of the pair of horizontal transfer rails and the rail spacing of the pair of moving rails do not necessarily have to be the same. A lateral transfer wheel that engages and a vertical transfer wheel that engages the moving rail will be provided.

(Operation) In the above horizontal circulating parking apparatus, the length required on the carrier side of the conveyor chain for positioning the two sets of moving rails adjacent to each other on the extension lines of the two horizontal transfer paths is as follows.
If the rail spacing of one set of moving rails is RG and the spacing between moving rails of adjacent groups is S, then 2 × RG + S, and there are three sets of moving rails on the conveyor chain, so the rest of the conveyor chain Has a length of 2 × S + RG. In this case, since S> RG, it becomes 2 × S + RG> 2 × RG + S, and the sprocket at both ends is suspended to secure a return side length comparable to the carrier side with the remaining length of the conveyor chain. be able to.

The three sets of moving rails are arranged at a pitch corresponding to the pallet transfer stroke in the vertical transfer path, that is, at a pitch longer than the length of the pallet in the vertical transfer direction. When the conveyor chain is run for one pitch of the moving rail from the state where the two moving rails are positioned on the side, the remaining one moving rail on the return side moves to the carrier side,
The pair of moving rails that were at the rear position on the carrier side first move to the front position on the carrier side. That is,
Two sets of moving rails will be located on the carrier side,
Even in this state, the pallets can be transferred from one horizontal transfer path to one vertical transfer path, and at the same time, the pallets can be transferred from the one vertical transfer path to the other horizontal transfer path.

Therefore, as described above, the total length of the conveyor chain is three times the above-mentioned transfer stroke because three sets of moving rails are arranged on the conveyor chain at a pitch corresponding to the transfer stroke of the pallet in the vertical transfer path. Is the length of 4
It is shorter than the conventional one that requires double the length, and the sprocket spacing at both ends of the lateral transfer conveyor chain can be reduced accordingly.

Therefore, according to the present invention, three sets of moving rails having a rail interval shorter than the length of the pallet in the vertical transfer direction are arranged on the conveyor chain of the vertical transfer path between adjacent sets of moving rails. Since they are arranged at regular intervals wider than the rail intervals and at a pitch longer than the length of the pallet in the vertical transfer direction, two sets of two moving rails are moved by traveling the conveyor chain. While making it possible to connect to each of the horizontal transfer paths simultaneously, the total length of the conveyor chain can be shortened and, by extension, the driving part of the vertical transfer path can be kept within the range of the movement path of the pallet to increase the vehicle accommodation rate of the parking space. As well as being able to increase
Since the total length of the conveyor chain is shortened and the number of moving rails can be reduced, the structure of the parking device is simplified.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show a parking facility in which horizontal circulating parking devices are provided in upper and lower two layers.

In the figure, 1 is an upper-level parking device, 2 is a lower-level parking device, and is provided in the basement of the building 3. Upper parking system 1
Is a pair of parallel laterally extending rails 5 that support a pallet 4 for mounting a vehicle and guide its transportation.
The first and second horizontal transfer paths 6 and 7 are provided in parallel with each other, and are provided between both ends of both the horizontal transfer paths 6 and 7, respectively. The first and second vertical transfer paths 8 and 9 for moving the pallet 4 between the ends of the paths 6 and 7 constitute a rectangular horizontal circulation path for circulating the pallet 4. A horizontal transfer means 10 for moving the pallet 4 laterally is provided at the central position of each horizontal transfer path 6, 7. The lower parking apparatus 2 also has substantially the same configuration as the upper parking apparatus 1.

First, the horizontal transfer rails 5 and 5 of both the horizontal transfer paths 6 and 7 engage the horizontal transfer wheels 4a on the lower surface of the pallet 4 to support the pallet 4 so as to be horizontally movable. ,
Support 12 consisting of columns, beams, etc. assembled on the basement floor 11
It is fixed and supported by. Then, the lateral transfer means 10
Is provided with a crank arm 14 rotated around a vertical axis by a driving means 13, and rollers provided at both ends of the crank arm 14 are engaged with groove members 15 provided on the lower surface of the pallet 4 to rotate the crank arm 14. The pallet 4 is moved laterally.

On the other hand, the vertical transfer paths 8 and 9 are the two sprockets 16 and 16 located on the first horizontal transfer path 6 side and the second horizontal transfer path 7 respectively.
Two endless conveyor chains 18 and 18 are provided so as to be suspended by two sprockets 17 and 17 located on the side and are arranged so as to be able to travel in a vertical direction orthogonal to the horizontal transfer rails 5 and 5. The two conveyor chains 18, 18 extend in parallel with the horizontal transfer rail 5 and three sets of moving rails 19a, 19a, 19a, 19a, which support the pallet 4 movably in pairs.
19b, 19b, 19c, 19c are arranged and fixed at an equal pitch P along the traveling direction of the conveyor chain 18. These moving rails 19a to 19c engage the vertical transfer wheels 4b and 4b provided on the lower surface of the pallet 4 to support the pallet 4.

That is, as shown in FIG.
The rail distance RG of 19a to 19c is different from the rail distance W between the pair of horizontal transfer rails 5 and 5 in the horizontal transfer paths 6 and 7 (corresponding to the distance between the horizontal transfer wheels 4a and 4a of the pallet 4). It is formed narrower than this. For this reason, the pallet 4 is provided with wheels 4a, 4a for horizontal transfer and wheels 4b, 4b for vertical transfer separately.

Then, as shown in FIG. 4, the above three sets of moving rails are provided.
19a ~ 19c, between the adjacent moving rails of the adjacent group,
Each of them is arranged at a constant interval S wider than the rail interval RG. And these three sets of moving rails 19
The arrangement pitch P of a to 19c, that is, (RG + S), is the vertical transfer paths 8 and 9 for transferring the pallet 4 between the horizontal transfer paths 6 and 7.
With a length comparable to the vertical transfer stroke of the pallet 4 in
Specifically, it is set to a dimension longer than the length of the pallet 4 in the vertical transfer direction. As a result, the total length of the conveyor chain 18 is three times as long as the vertical transfer stroke.

Further, as shown in FIG. 3, guide rails 21 and 21 are provided on both outer sides of the conveyor chain 18, respectively. Furthermore, on both outer sides of both guide rails 21,21,
Considering the elongation due to the use of the conveyor chain 18,
Compensation rails for lateral transfer wheels 4a and vertical transfer wheels 4b
22, 23 and stopper rails 24, 25 are provided so as to be supported by the support members 26, 26.

The guide rails 21 and 21 are for moving the moving rails 19a to 19c in a horizontal state.
Guide rollers 27, 27 provided at both ends of a to 19c are engaged with each other to roll.

The correction rails 22 and 23 are provided between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9. That is, the correction rail 22 of the lateral transfer wheel 4a is located on the extension line of the lateral transfer rail 5, is pivoted on the support member 26 with the lateral transfer rail side as a fulcrum, and the middle portion is formed into an elongated hole. By applying an adjusting screw (not shown), the conveyor chain 18 can be appropriately rotated and fixed in the extending direction. The correction rails 23 of the vertical transfer wheels 4b are located on the extension lines of the movement loci of the vertical transfer wheels 4b in the horizontal transfer paths 6 and 7, and in the same manner as the correction rails 22, the horizontal transfer paths 6 and 7 are provided. Conveyor chain as a fulcrum 1
It can be fixed by rotating it appropriately in the direction of extension of 8.

The stopper rails 24 and 25 are respectively provided at positions facing the rails 22 and 23 across the vertical transfer paths 8 and 9, and in the same manner as the correction rails 22 and 23, the support member 26 of the conveyor chain 18 is provided. It can be fixed by rotating it appropriately in the extension direction.

On the opposite side of the first horizontal transfer path 6 across the first vertical transfer path 8, the pallet 4 is provided between the entrance / exit 30 of the vehicle on the ground and the upper and lower parking devices 1 and 2. Lifting means 3 for lifting
1 is provided. The lifting means 31 is a pallet mounting table 32.
Is connected to a conveyor chain (not shown) which is engaged with the guide 33 and driven by the motor 34. In addition, each pallet 4 is provided with a connector that can be connected to the adjacent pallet 4, and the connection is released when the pallet 4 is vertically transferred.

The vertical transfer paths 8 and 9 are provided with tensioning means (not shown) that adjusts the length between the sprockets 16 and 17 to apply tension to the conveyor chain 18.

Therefore, in the case of the above parking facility, the vehicle is on the ground entrance / exit 30
From the lifting means 31 to the pallet 4 and the lifting means 31
Is transferred to the upper parking device 1 or the lower parking device 2. Then, each pallet 4 is basically sent from the first vertical transfer path 8 to the first horizontal transfer path 6 and then to the first vertical transfer path 9 via the second vertical transfer path 9 and the second horizontal transfer path 7. It is designed to circulate throughout. In addition, upon unloading, each pallet 4 is moved in an appropriate direction on the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9 so that the pallet 4 on which the corresponding vehicle is placed can be moved to the location of the lifting means 31 in the shortest distance. It will be transferred. In this case, the transfer of each pallet 4 is performed by the first and second vertical transfer paths 8,
An empty space is formed on the side of the first horizontal transfer path 6 or the side of the second horizontal transfer path 7 in 9. That is, the pallets 4 can be transferred along the horizontal transfer paths 6 and 7 by feeding the pallets 4 into the empty spaces from the horizontal transfer paths 6 and 7.

Therefore, in transferring the pallet 4 between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9, two sets of the three transfer rails 19a to 19c of the vertical transfer paths 8 and 9 are used. It must be connected to the lateral transfer paths 6,7. In this case, 3 sets of moving rails 19a-1
When one set of the moving rails 9c, for example, the moving rails 19a, 19a is in the connection position with the first lateral transfer path 6, the moving rail pitch P
Corresponds to the vertical transfer stroke, so that the moving rails 19b, 19b of the adjacent set come to the connection position with the second horizontal transfer path 7. Therefore, the pallets 4 can be simultaneously transferred between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9.

Further, when the conveyor chain 18 is further traveled by one pitch, for example, the moving rails 19a and 19a are moved to the conveyor chain 1
As the moving rails 19b, 19b move to the connection position with the first horizontal transfer path 6 by turning to the return side of 8, the moving rails 19c, 19c on the return side turn to the carrier side and move to the second horizontal transfer path 7 It will come to the connection position with and eventually the moving rail
19b and 19b are connected to the first and second horizontal transfer paths 8 and 9 so that the pallets 4 can be transferred simultaneously between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9. Is.

Then, as described above, the total length of the conveyor chain 18 is
Since the length of the pallet 4 is three times the vertical transfer stroke, the length of the pallet 4 is shorter than that of the conventional pallet which requires four times the vertical transfer stroke. Therefore, the distance between the sprockets 16 and 17 at both ends is shortened by one stroke, that is, 1/2 stroke.
It becomes possible to put the sprockets 16 and 17 at both ends and the drive parts thereof within the range of the pallet movement locus in the parking device, and even if the building 3 has a pillar that has traveled from the wall, the sprockets 16 and 17 can be stored. The movement path of the pallet 4 can be expanded and the utilization efficiency of the parking space can be improved without causing interference with the above.

Further, the transfer of the pallet 4 between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9 is performed as follows.

For example, in transferring the pallet 4 from the first horizontal transfer path 6 to the first vertical transfer path 8, the horizontal transfer wheel 4a on the front side in the transfer direction.
Is transferred from the horizontal transfer rail 5 to the correction rail 22, and at the same time, the vertical transfer wheel 4b on the front side in the transfer direction, which was suspended in the first horizontal transfer path 6, rides on the correction rail 23. Subsequently, the horizontal transfer wheels 4a are suspended in the first vertical transfer path 8 while the vertical transfer wheels 4b are moved from the correction rail 23 to the moving rail 19a. Then, both the wheels 4a, 4b for horizontal transfer and for vertical transfer on the rear side in the transfer direction are suspended in the same manner as the wheels on the front side, and are moved to the moving rail 19a, and then moved from the first horizontal transfer path 6 to the first side. The transfer of the pallet 4 to the 1 vertical transfer path 8 is completed.

The transfer of the pallet 4 from the first vertical transfer path 8 to the second horizontal transfer path 7 is the reverse of the above transfer.

Then, when elongation occurs in the conveyor chain 18, while applying tension to the conveyor chain 18 by a tensioning means, in accordance with the amount of expansion of the conveyor chain 18, the correction rails 22, 23 and By rotating the stopper rails 24 and 25 to be inclined, the pallets 4 can be smoothly transferred between the horizontal transfer paths 6 and 7 and the vertical transfer paths 8 and 9.

In the above embodiment, the pallet 4 is provided with two sets of wheels for horizontal transfer and vertical transfer, but the rail interval W between the horizontal transfer rails 5, 5 is narrowed to the same as the rail interval RG of the moving rail. One set of wheels may be used for both horizontal transfer and vertical transfer.
