[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional storage tower such as a multi-story parking device.

[0002]

2. Description of the Related Art As a conventional multi-story parking device, there is one as shown in FIG. In the three-dimensional parking device,
The storage spaces K are provided side by side on the left and right sides of the elevating space S extending in the vertical direction (the direction of the front and back of the paper). The elevating space S and the storage space K are provided with the first and second roller frames 51 and 5.
Each is divided into a plurality of floors by two. The traversing trays 53A and 53B on which the automobiles are placed have a storage space K.
In the storage room K1 formed on each floor.
The traversing trays 53A and 53B can traverse the same floor between the storage room K1 and the elevating space S when the vehicle enters and leaves the vehicle. The elevating lift 54 is provided to be able to move up and down in the elevating space S. The traversing tray 53A, 5
The 3B and the lifting lift 54 have alternately comb-shaped forks 53a and 54a. Therefore, the traversing tray 53
A, 53B and the lift 54 pass each other with the forks 53a, 54a in the lift space S, so that the vehicle is delivered between the two 53A, 53B, 54.

As a traversing mechanism for traversing the traversing trays 53A and 53B, a plurality of first and second guide rollers 55 and 56 are provided on the first and second roller frames 51 and 52, respectively. (Four on each roller frame 51, 52). The traversing motors 57A, 57B, 57C such as electric motors
The first and second guide rollers 55 and 56 are independently driven by the roller frames 51 and 52 via a chain 58. Therefore, between the storage room K1 on the left side of the drawing and the lift space S,
When the movement of A is performed, the traversing motors 57A, 57A
When B moves the traversing tray 53B between the right storage room K1 and the elevating space S, the traversing motors 57B and 57C are driven, respectively. It should be noted that guide rollers 55,
The drive of the traversing motors 57A, 57 is connected only to one of the front and rear roller frames 51, 52.
B and 57C may be arranged.

[0004]

However, the above prior art has the following problems. (1) The traversing mechanism includes first and second guide rollers 5
5, 56 and the traversing trays 53A, 5 placed on it.
3B, the transverse tray 53A,
53B is traversed. Here, in order to surely move the traversing trays 53A, 53B between the storage room K1 and the elevating space S, the contact between each guide roller 55, 56 and the traversing trays 53A, 53B is ensured. Needs to be done. That is, each guide roller 5
It is necessary to accurately assemble the rollers 5 and 56 with the roller frames 51 and 52. Accordingly, for example, when holes for accommodating the bearings of the guide rollers 55, 56 are formed in the roller frames 51, 52, the holes must be finished with high precision by boring or the like, which increases the processing cost. Was.

(2) Each of the roller frames 51, 5 is so moved as to ensure that the traversing trays 53A, 53B are traversed.
All the four guide rollers 55 and 56 arranged in 2 are driven and rotated. Therefore, the problem of the processing cost of (1) has been serious.

(3) The traversing mechanism includes a traversing tray 53
A, guide rollers 55 and 56 supporting 53B are directly
In order to rotate, the traversing motors 57A, 57B, 57 are moved between the first guide roller 55 and the second guide roller 56.
It was difficult to standardize C. That is, for example, the second guide corresponding to the first guide roller 55 and the traversing tray 53A
It is assumed that both traversing motors 57A and 57B of the guide roller 56 are shared. In this case, when the traversing tray 53B traverses, the first guide roller 55 is driven and rotated, and the second guide roller 56 corresponding to the traversing tray 53A is unnecessarily driven and rotated via the power transmission system. In order to prevent this, a mechanism for transmitting / cutting power must be interposed between the common traversing motor and the second guide roller 56, which is a very complicated mechanism. is there.

Therefore, in the prior art, the traversing motors 57A, 57B, 57C for driving the first and second guide rollers 55, 56 are independently provided on both the first and second roller frames 51, 52. Was provided.
As a result, expensive traversing motors 57A, 57B, 57C
, And the cost of the traversing mechanism is increased. In addition, the left or right traversing tray 53A, 5
Each of the traversing motors 57A, 57A according to the traversing movement of 3B.
The ON / OFF and rotation directions of B and 57C must be controlled independently, and the control circuit is complicated.

As described above, the conventional multi-story parking device requires a cost for the traversing mechanism of the traversing trays 53A and 53B.
The cost of the entire apparatus was increased. SUMMARY OF THE INVENTION The present invention has been made in view of the problems existing in the prior art, and an object of the present invention is to provide a three-dimensional storage tower capable of inexpensively configuring a traversing mechanism of a traversing tray. .

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a pair of front and rear followers formed on the traversing tray and extending along the moving direction of the traversing tray, In the space, a pair of front and rear first rotators arranged so that the original section formed on the outer peripheral side thereof intersects the movement trajectory of the follower section, and the follower section in the storage space A pair of front and rear second rotators arranged so that the original section formed on the outer peripheral side thereof intersects the movement locus, and an interlocking shaft rotatably mounted between the roller frames, A pair of front and rear drive chains wound between sprockets fixed to the rotating shafts of the first and second rotating bodies and both end portions of the interlocking shaft, respectively, and the first and second rotating bodies are fixed together with the interlocking shaft. Turn in the opposite direction And a driving means for driving, by said first and second rotors are rotated in forward and reverse directions,
The traversing tray is configured to be moved between the same floors of the storage space and the lift space, and the storage space is located on both sides of the lift space.
Side, and corresponds to one of the traversing trays
The rotating body has its original section shifted to the follower section of the other traversing tray.
It is a three-dimensional storage tower located at a position that does not intersect with the moving trajectory .

According to the second aspect of the present invention, the four corners of the lifting space
A lifting frame is arranged in the drive chain.
It is routed outside the frame.

[0011]

(Operation) In order to store a stored object in the first aspect of the present invention, the stored object is placed on an elevating lift and moved up and down the elevating space to a predetermined floor.
The stored items moved up and down to a predetermined floor are stored by moving the traversing tray from the elevating space to the storage space.

[0013] When a stored object is to be unloaded, the traversing tray on which it is placed is traversed from the storage space to the elevating space. And the stored items moved to the lifting space,
It is moved to the floor at the unloading position by the lift.

Here, the movement of the traversing tray between the storage space and the elevating space is performed by rotating the first and second rotating bodies in the forward and reverse directions by driving the driving means. That is, for example, it is assumed that the traversing tray is in the storage space. In this state, the original section of the second rotating body intersects the follower section of the traversing tray. Accordingly, the traversing tray is moved toward the elevating space by a moving force given by the second rotating body.

When the traversing tray is moved to a certain section between the storage space and the elevating space, the original section of the first rotating body intersects the follower section. Therefore, in this section, the traversing tray is fed to the lifting space by the moving force given by the two rotating bodies.

Further, as the traversing tray is moved into the elevating space, the engagement between the original section of the second rotating body and the follower section of the traversing tray is released. Accordingly, in the subsequent sections, the traversing tray is moved into the elevating space by applying a moving force only by the first rotating body.

In order to traverse the traversing tray in the elevating space to the storage space, first and second driving means are used.
What is necessary is just to rotate a rotating body in the opposite direction to the above. Also, drive
The driving force of one drive source is transmitted to the first and second rotating bodies by the moving chain, and the first and second rotating bodies are rotated.
That is, the driving source is shared between the two rotating bodies.

Further, the follower portions are formed in a front and rear pair , and the first and second rotating bodies and the drive chain are arranged in a pair corresponding to the respective follower portions. That is, the moving force is distributed and applied to the traversing tray at a plurality of locations, and the traversing movement of the traversing tray is stabilized.

Also, the driving force of one driving source is transmitted to the first and second rotating bodies on the front side , and is transmitted via the interlocking shaft.
The first and second rotating bodies on one side are rotated. In other words, before and after
A drive source is shared between the pair of first and second rotating bodies.

[0020] Before Symbol storage space is arranged on both sides of the elevating space, the first rotating body that corresponds to one of the transverse tray, its HaraTakashi portion does not intersect the moving locus of the followers of the other of the transverse tray Is located in the position. Therefore, the traversing movement of one traversing tray causes the first traversing tray to correspond to the first traversing tray.
The rotating body is not driven and rotated. As a result, for example, even when the drive source is shared between the first and second rotating bodies, it is possible to prevent the second rotating body corresponding to the other transverse tray from being unnecessarily driven and rotated via the power transmission system. it can. Contract
In the invention according to claim 2, the drive chain is provided on the lifting frame.
It is handled on the outside. Therefore, the lift space (lift
Trajectory of the lifting lift).

Each storage space K is divided into a plurality of floors by the second roller frame 15, and a storage room K1 is formed on each floor.

The second guide roller 16 is provided in the accommodation room K on each floor.
In FIG. 1, the second roller frames 15 are rotatably provided on opposing surfaces. Second guide roller 16
Are arranged at predetermined intervals along the longitudinal direction of each second roller frame 15. The first and second guide rollers 14 and 16 are constituted by free rollers.

The elevating lift 17 includes a pair of lift frames 18 extending in the front-rear direction on both left and right sides of the elevating space S, and a comb-tooth-like shape protruding from the lift frames 18 toward the lift frames 18 opposed to each other. And a fork 19. The front and rear ends of each lift frame 18 are front and rear elevating frames 12A-1

As shown in FIGS. 2 and 5, a pair of balance chains 20 are disposed on the left and right sides in the lift space S. The guide sprockets 21A and 21B
Each of the lift frames 18 is rotatably disposed at the front and rear ends. The balance chain 20
Are inserted through the inner space of each lift frame 18 in a substantially horizontal state. The rear end of each balance chain 20 is raised via a guide sprocket 21B, and the raised end is fixed to the upper ends of the rear lifting frames 12C and 12D. The other end of each balance chain 20 is lowered via the guide sprocket 21A, and the lower end is fixed to the lower end of the front lifting frame 12A, 12B.

The counter shaft 22 is rotatably supported between the upper ends of the front elevating frames 12A and 12B, and is rotated by a motor 23 fixed to the upper end of the right elevating frame 12B. It is driven to rotate in the direction. The pair of driving sprockets 24 are fixedly arranged at positions corresponding to the inner spaces of the front-side elevating frames 12A and 12B on the counter shaft 22.

One end of the lift chain 26 is fixed to the front end of the lift frame 18 of the lift 17, and a balance weight 27 is attached to the other end. The balance weight 27 adjusts the weight balance with the lift 17.

Here, the balance chain 20 has a guide sprocket 21 at a height difference between its rising end and the falling end.
It has a length substantially equal to the length obtained by adding the distance between A and 21B (crossing distance). Therefore, the front end side of the lift frame 18 is suspended and supported by the lift chain 26, so that the guide sprocket 21A, the balance chain 20
The rear end of the lift frame 18 is also held at substantially the same height as the front end by the linkage of the guide sprocket 21B and the guide sprocket 21B.
That is, the lift 17 is supported in a substantially horizontal balance.

When the lift chain 26 is moved in one direction or the other direction by driving the lift motor 23, the front end of the lift 17 is raised or lowered. The rear end of the elevating lift 17 is moved up and down through the guide sprocket 21A, the balance chain 20, and the guide sprocket 21B in conjunction with the elevating operation on the front end side. Therefore, the lift 17 is guided by the lift frames 12A to 12D and moves up and down in the lift space S while maintaining a substantially horizontal state.

The traversing trays 28A and 28B are fitted to the second guide rollers 16 with “U” -shaped inner spaces of the guide frames 30, respectively.
5 supported. Traversing tray 28A, 28B
Is always stored in the storage room K1 on each floor,
When the vehicle C enters and leaves the vehicle, the vehicle C is guided and supported by the second guide roller 16 and the first guide roller 14 disposed at the same height position as the second guide roller 16.
1 and the ascending / descending space S can be traversed between the same floors.

The entry / exit room F is provided on the lowest floor of the elevating space S, and the entry / exit room F is an entrance / exit of the automobile C to / from the multi-story parking device. The floor 32 is provided in the lower part of the loading / unloading room F, and although not shown, the left and right sides of the floor 32 have the same shape as the forks 31 of the traversing trays 28A and 28B, that is, the forks 19 of the lift 17 And a fork alternately formed.

Next, a traversing mechanism for traversing the traversing trays 28A and 28B will be described. Figure 2
As shown in FIG. 4, the chain portion 35 as a follower portion is provided on both the guide frames 3 in each of the transverse trays 28A and 28B.
0 are provided on the upper surface. The chain part 35
In the longitudinal direction of the guide frame 30 (the traversing tray 28
A, 28B).

The first and second bearings 36 and 37 are disposed on the upper surfaces of the front and rear first and second roller frames 13 and 15, respectively, near the elevating frames 12A to 12D. Each pair of first traversing sprockets 38 as first rotating bodies is rotatably supported by first bearings 36. Each pair of second traversing sprockets 39 as the second rotating body is rotatably supported by the second bearing 37. As shown in the enlarged circle of FIG. 4, the first and second traversing sprockets 38, 39 have teeth 38a, 39a as original nodes formed on the outer peripheral side thereof.
They are arranged so as to intersect the movement trajectory of the chain portion 35 of each of the traversing trays 28A and 28B (the teeth 38a of the first traversing sprocket 38 have a similar configuration, not shown). The first and second traversing sprockets 38, 3
9 is arranged such that at least one of the trays 28A, 28B is always engaged with the chain portion 35 when the traversing trays 28A, 28B are moved between the storage room K1 and the elevating space S.

The interlocking shaft 40 is rotatably mounted between the front and rear second roller frames 15. Sprockets 38b, 39b, 40a, 40b are fixed to the rotating shafts of the first and second transverse sprockets 38, 39 and to both ends of the interlocking shaft 40, respectively. The drive chain 41 includes front sprockets 3 and rear sprockets 3.
8b, 39b, and 40a (40b). The drive chain 41 is provided so as not to be interfered by the elevating space S (elevation locus of the elevating lift 17).
It is routed outside the lifting frames 12A to 12D.

Traversing motors 42A and 42 as drive sources
Reference numeral B denotes an electric brake motor, which is disposed above the second bearing 37 on the front side. The traversing motors 42A and 42B are meshed with the drive chain 41 on the rear side with a sprocket 42a attached to the drive shaft. Accordingly, the first and second traverse sprockets 38, 3 on the front side are driven by the traverse motors 42A, 42B.
9 is rotated, and the first and second traversing sprockets 38, 39 on the rear side are also interlockedly rotated in the same direction via the interlocking shaft 40. Tension adjusting roller 43
Are interposed in each drive chain 41. By changing the position of the tension adjusting roller 43 with respect to the second roller frame 15, the tension of the drive chain 41 can be adjusted.

Note that the chain portions 35 are not provided in the guide frame 30 near the lifting space S. Therefore, for example, as shown in FIG. 7, it is assumed that the traversing tray 28B (28A) on the right side (left side) in the drawing is moved to the lifting space S. In this case, only the right (left) first traversing sprocket 38 is engaged with the chain portion 35, and the left (right) first traversing sprocket 38 is engaged.
However, it is not engaged with the chain portion 35. In other words, the movement trajectory of the chain portion 35 of one of the traverse trays 28B (28A) corresponds to the other traverse tray 28A (28A).
The teeth 38a of the first traverse sprocket 38 corresponding to (28B) do not cross each other.

Now, as shown in FIG.
In the state where A and 28B are stored in the storage room K1, only the second traversing sprocket 39 is moved to the traversing trays 28A and 28A.
B is engaged with the chain portion 35. In this state, for example, when the traversing motor 42B is driven, the first and second traversing sprockets 38, 3 connected thereto are driven.
9 is rotated in one direction. Therefore, the traversing tray 28B
Is moved by the second traversing sprocket 39, which is in meshing relationship, to the traversing space S.

As shown in FIG. 6, the traversing tray 28B
Comes to an intermediate position between the storage room K1 and the elevating space S, the first traversing sprocket 38 is also meshed with the chain portion 35. Therefore, the traversing tray 28B is
And the second traversing sprockets 38 and 39 provide a moving force.

As shown in FIG. 7, as the traversing tray 28B is moved to the elevating space S, the traversing tray 28B and the second traversing sprocket 39 are disengaged from each other. Therefore, after that, the first traversing sprocket 38
The movement force is provided only by the above.

In order to store the traversing tray 28B arranged in the elevating space S in the storage room K1, the traversing motor 42
The first and second traversing sprockets 38, 39 may be rotated in the opposite direction by B.

Next, the operation of the multi-story parking device having the above configuration will be described. (Storing Operation) In order to store the car C in the multi-story parking device, the lift 17 is moved and arranged below the floor 32 (the state shown in FIG. 1). In this state, the vehicle C enters the loading / unloading room F and stops on the floor 32. By raising the lift 17, the fork 19 of the lift 17 and the fork of the floor 32 pass each other, and the vehicle C on the floor 32 is transferred to the lift 17.

The lift 17 carrying the car C is lifted in the lift space S and stopped at a position above the floor to which the predetermined storage room K1 belongs. Thereafter, the traversing tray 28A (28B) in the storage room K1 is traversed to the elevating space S by the above-described operation. In this state, when the lift 17 is lowered, the fork 19 of the lift 17 and the fork 31 of the traversing tray 28A (28B) are moved.
And the traversing tray 28A
The vehicle C is delivered to (28B). Car C
Tray 28A (28B) receiving the
1, and the vehicle C is stored in a predetermined storage room K1.

(Exiting Operation) In order to take out the car C from the multi-story parking device, the storage room K in which the car C is stored.
The first traversing tray 28A (28B) is traversed to the elevating space S. By raising the lift 17 in this state, the fork 19 of the lift 17 and the fork 31 of the traversing tray 28A (28B) pass each other, and the vehicle C is moved from the traversing tray 28A (28B) to the lift 17. Is passed.

The lift 17 carrying the car C is temporarily stopped at a position above the floor of the storage room K1, and the traversing tray 28A (28) located in the lift space S during that time.
B) is traversed to its own storage room K1. Then, the lift 17 is lowered to the lowest floor, and the lift 17
Of the fork 19 and the fork of the floor 32 pass each other, and the automobile C is delivered to the floor 32 from the elevating lift 17. Then, when the car C is put out of the entry / exit room F, the exit is completed.

The present embodiment having the above configuration has the following effects. (1) Due to the meshing relationship between the chain portions 35 of the traversing trays 28A, 28B and the first and second traversing sprockets 38, 39, the traversing trays 28A, 28B are stored in the storage room K1.
And the ascending / descending space S are traversed between the same floors. Therefore, the first and second guide rollers 14 and 16 may be free rollers, and each roller frame 1 of the free rollers may be a free roller.
Not much accuracy is required for attachment to 3,15. Accordingly, holes provided in the roller frames 13 and 15 for accommodating bearings (not shown) that support the first and second guide rollers 14 and 16 are, for example,
Processing with only punch holes is sufficient, and the processing cost can be greatly reduced.

(2) First and second traversing sprockets 3
Only by adjusting the arrangement positions of the trays 8 and 39 and the arrangement position of the chain portion 35 formed on the traversing trays 28A and 28B, the other traversing trays 28A and 28
The first traverse sprocket 38 corresponding to B is not engaged. Therefore, the traversing motor 42 for rotating and driving the first and second traversing sprockets 38 and 39 is used.
A and 42B could be shared without a complicated power transmission system (power transmission / shutoff mechanism). Therefore, a control circuit (not shown) that controls the small number of traversing motors 42A and 42B can simplify the configuration.

(3) By interposing the interlocking shaft 40 between the front and rear drive chains 41, the first and second traversing sprockets 38 and 39 on the rear side can be replaced with the first and second traversing sprockets 38 on the front side. , 39.
Therefore, the front and rear first and second transverse sprockets 38,
The 39 traversing motors 42A, 42B can be shared, and in addition to the above (2), the traversing motors 42A, 42B are provided on each floor.
Only two 2Bs are arranged, which is more effective for simplifying the control circuit.

As described above, according to (1) to (3), the cost of the traversing mechanism can be reduced, and the multi-story parking device can be provided at low cost. In addition, the following effects are obtained.

(4) The chain portion 35 is provided with the traversing tray 28
A and 28B are provided on both sides, and first and second traversing sprockets 38 and 39 are provided corresponding to the two. That is, the driving force of each of the traversing motors 42A and 42B is applied to two places on both sides of the traversing frames 28A and 28B. Therefore, for example, the traversing motor 42
The horizontal movement of the horizontal frames 28A, 28B is performed more stably than in the case where the driving force of the horizontal frames A, 42B is applied at one place in the center of the horizontal frames 28A, 28B.

(5) The first and second traversing sprockets 38 and 39 are provided with first and second guide rollers 14 and 16.
Are arranged on the opposite side with respect to the chain portion 35. Therefore, the traversing trays 28A, 28B are in a state of being sandwiched by the first and second traversing sprockets 38, 39 and the first and second guide rollers 14, 16. As a result, the traversing of the traversing trays 28A and 28B is performed stably without slipping, and it is possible to suppress generation of noise, vibration, and the like due to unstable traversing.

(6) The traversing motors 42A and 42B are brake motors and cannot be driven to rotate. The chain portion 35 of the traversing trays 28A, 28B and the first and / or second traversing sprockets 38, 39 are always in a meshed state. Therefore, even if stress (for example, shaking due to an earthquake) is applied to the traversing trays 28A, 28B for some reason, unnecessary movement of the traversing trays 28A, 28B can be prevented.

Here, the first and second traversing sprockets 38 and 39 are moved to the traversing trays 28A and 28B side, and the chain portion 35 is moved to the first traverse.
And the second roller frames 13 and 15 may be provided. In this case, the traversing motors 42A and 42B
It is arranged on the side of the traversing trays 28A, 28B.
In such a configuration, the inventor of the present invention
Various attempts have been made to route the wiring from the external power supply to A and 42B (realistic in terms of cost, etc.). In either case, however, the horizontal movement of the traversing trays 28A and 28B caused the wiring to interfere with the elevating trajectory of the elevating lift 17, thereby hindering the elevating lift 17. Therefore, such a configuration is not a practical configuration because of its wiring.

The present invention can be practiced in the following modes without departing from the spirit of the present invention. (1) A traversing motor for rotating and driving the first traversing sprocket 38 and a traversing motor for rotating and driving the second traversing sprocket 39 are separately provided. This eliminates the need for the drive chain 41 or the like to transfer driving force between the two sprockets 38 and 39, thereby simplifying the power transmission structure of the traversing mechanism.

(2) A traversing motor for rotationally driving the first and second traversing sprockets 38, 39 on the front side, and the first and second traversing sprockets 38, 3 on the rear side.
9 is separately provided with a traversing motor for rotationally driving 9. By doing so, it is not necessary to transfer the driving force between the front and rear sprockets 38 and 39 by the interlocking shaft 40 and the like, and the power transmission configuration of the traversing mechanism can be simplified.

(3) The chain part 35 is changed to a rack, and the first and second traversing sprockets 3 are changed accordingly.
8 and 39 must be changed to gears such as pinions and worms that mesh with the rack.

(4) In the above embodiment, the chain portion 35
