Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal circulation type three-dimensional hangar. More specifically, the present invention relates to a multi-storey hangar such as a multi-storey parking lot or a multi-storey warehouse, in which a pallet stores cars and various articles, circulates in the same storage layer, is transferred to an elevator, and is loaded and unloaded. .

[0002]

2. Description of the Related Art A conventional horizontal circulation parking lot will be described with reference to FIG. In the figure, E is an elevator, and H is an arbitrary storage layer of a multilevel parking lot. Each storage layer H is divided into a grid pattern, and a pallet P on which automobiles are loaded in each division
Are arranged. The section indicated by the dotted line is the pallet P.
Means a section in which is not placed. A pallet transfer device is installed on the floor surface of each section.

A conventional pallet transfer device drives a roller by a motor or the like to feed the pallet P placed on the upper surface. In the longitudinal or width direction of the pallet P,
It is possible to feed in a reciprocating direction. Therefore, while the pallet P circulates in the reciprocating direction indicated by the arrow c, when the pallet P to be loaded and unloaded comes to a position adjacent to the elevator E, the vehicle is transferred to and from the elevator E (see the arrow b). Has become.

[0004]

However, in the conventional horizontal circulation parking lot, the circulation route of the pallet P is constant, and the pallet P can be moved only in the reciprocating direction. Therefore, depending on the position of the pallet, the linear distance from the elevator E may be small. Despite the fact that they are close to each other, they cannot come to the transfer position with the elevator unless they go all the way through the circulation route, and generally, there is a drawback that the loading and unloading time is long. This problem also applies to the three-dimensional warehouse.

In view of such circumstances, it is an object of the present invention to provide a horizontal circulation type three-dimensional hangar in which the warehousing time is greatly shortened.

[0006]

In the horizontal circulation type three-dimensional hangar of the present invention, a plurality of storage layers are arranged one above the other and each storage layer is partitioned in a grid pattern so that any one partition can be installed in an elevator. A pallet transfer device that is a three-dimensional hangar having an elevator room that moves up and down and all other compartments as storage rooms, and transfers pallets for loading and storing pallets to be stored in all storage rooms and elevators of each storage layer. The pallet transfer device is a bidirectional transfer type equipped with a vertical feed roller unit for feeding the pallet in the vertical direction and a horizontal feed roller unit for feeding the pallet in the horizontal direction. The three-dimensional hangar in the present invention is a concept that includes both a three-dimensional parking lot and a three-dimensional warehouse.

[0007]

According to the present invention, since the pallet transfer device is provided with the vertical feed roller unit and the horizontal feed roller unit and can feed the pallet in the vertical direction and the horizontal direction, the pallet to be loaded and unloaded from the pallet and the elevator at the minimum. By selecting the required path and sequentially driving only the pallet transfer device on the selected path, the object to be stored can be moved to (or from) the elevator at the shortest distance. Since each storage layer of the three-dimensional storage is connected by the elevator, the selective circulation operation of all the storage layers is organically linked, and the storage time of the entire three-dimensional storage can be shortened.

[0008]

EXAMPLES Next, the present invention will be described based on examples suitable for a three-dimensional parking lot. The multi-storey parking lot of the present invention has both a storage layer (aboveground storage layer) provided above the loading / unloading layer and a storage layer (underground storage layer) provided below (the intermediate loading system), as well as above ground. This includes those provided with only a storage layer (lower loading method) or those provided with only an underground storage layer (upper loading method), but the following will describe a lower loading multilevel parking lot.

First, the basic structure of the multi-storey car park according to this embodiment will be described. FIG. 1 is a schematic perspective view of a multilevel parking lot according to the present embodiment. The storage layers are four layers 1F to 4F, and each storage layer is partitioned in a grid pattern and has five rows in the width direction and four rows in the vertical direction. However, the number of columns and the number of columns are not limited to the above, and the number of columns can be about 2 to 20 and the number of columns in the width direction and the vertical direction can be about 2 to 10. EH is the elevator room, the lowest level
It is provided vertically from the 1st floor to the 4th floor. The position of this elevator room EH is arbitrary.

FIG. 2 is a plan view of the storage layers 2F-4F,
FIG. 3 is a plan view of the lowermost storage layer 1F. E is an elevator, and 1 in FIG. 3 is an entrance / exit. A pallet transfer device M is installed in all sections of the elevator E and the storage layers 1F to 4F. On both sides in the width direction of the elevator E, the pallet P is usually not placed and the pallet P is placed in an empty pallet state, and the pallet P is placed in all remaining sections. In addition, M1 and M2 indicate transfer devices in which a pallet is not mounted on the upper surface.

Next, the pallet transfer device M and the pallet P
The details of the elevator E will be described. 4 is a plan view of the pallet transfer device M, and FIG. 5 is a plan view (A) and a side view (B) of the lateral feed roller unit 8. In FIG. 4, 2
Is a rectangular base frame, and vertical feed roller units 3 are installed on both edges of the upper surface in the width direction, and horizontal feed roller units 8 are installed on both ends in the longitudinal direction. Each of the vertical feed roller units 3 has about five vertical feed rollers 4 axially supported by a fixed frame 5 and has a chain 6 or the like.
And is driven by the motor 7. In addition, the horizontal feed roller unit 8 includes a plurality of horizontal feed rollers 11 on the lifting frame 9.
Is rotatably supported and is driven by the motor 12.

The traverse roller unit 8 will be described in detail with reference to FIG. 5. Reference numeral 13 is a chain, which is wound around a sprocket 14 coaxial with each roller 11, and a single motor 12 is provided.
The rotational driving force of is transmitted to all the rollers 11. Further, the elevating frame 9 is provided with an elevating mechanism described below. Reference numeral 15 is a tilting link, and 16 is a lifting cylinder. A transmission link 17 is connected to both ends of the tilting link 15, and a support shaft 19 is connected to the other end of the transmission link 17 via an arm 18. The support shaft 19 has an eccentric shaft portion 19a, and the eccentric shaft portion 19a supports the elevating frame 9. Therefore, when the lift cylinder 16 is driven to rotate the eccentric shaft portion 19a via the tilting link 15 and the transmission link 17, the lift frame 9 moves up and down according to the amount of eccentricity, and the upper surface position of the lateral feed roller 11 is increased. Moves up and down.

FIG. 6 is a perspective view of the upper surface of the pallet P, and FIG. 7 is a perspective view of the lower surface of the pallet P. In FIG. 6, reference numeral 20 denotes a mounting surface on which an automobile is loaded, and guards 21 are provided on both side edges. On the back surface of the pallet P shown in FIG. 7, a vertical feed rail groove 22 on which the vertical feed roller 4 of the pallet transfer device M travels and a lateral feed rail groove 23 on which the horizontal feed roller 11 travels are formed.

FIG. 8 shows a state in which the pallet P is placed on the upper surface of the pallet transfer device M. The right side of the drawing shows a state in which the horizontal feed roller 11 is lowered, and in this case, the horizontal feed roller 11 is separated from the horizontal feed rail groove 23 and is in a posture of being vertically fed by the vertical feed roller 4. The left side of the figure shows the posture in which the horizontal feed roller 11 is lifted up. In this case, the vertical feed roller 4 is separated from the vertical feed rail groove 22, and the pallet P is in the state of being fed horizontally.

As described above, in the pallet conveying device M, the feeding direction applied to the pallet P can be switched between the vertical direction and the horizontal direction by selecting the elevation position of the lateral feed roller unit 8.

FIG. 9 is a schematic perspective view of the elevator E, FIG. 10 is a plan view thereof, and FIG. 11 is a side view thereof. 9-10,
Reference numeral 26 denotes a rectangular base frame, which is provided with a vertical feed roller unit 3 and a horizontal feed roller unit 8 having the same configuration as the pallet transfer device M. In addition, guide rollers 27 are attached to the four corners of the base frame 26,
Guide rails 28 are provided upright at the four corners of the elevator room EH to move up and down.

30 shown in FIGS. 1 and 9 is an elevator E.
, 31 is a motor, 32 is a speed reducer, and 33 is a bevel gear box. With these, the wire ropes 34 fixed to the four corners of the elevator E are wound to raise and lower the elevator E. Reference numeral 35 is a counterweight, and in the present embodiment, the weight of the counterweight 35 is used to offset the weight of the vehicle loaded on the elevator E. However, a method of hoisting only by the motor power is adopted instead of such a method. It is very good. Therefore, as shown in FIG. 11, when the hoisting mechanism 30 is driven by placing the pallet P on which the vehicle C is loaded on the elevator E, the vehicle C is loaded into the storage layers 1F to 4F.
Can be transported between.

Next, the loading / unloading operation of this embodiment will be described. In FIG. 2, when the vehicle is to be unloaded from the pallet indicated by the reference symbol P1, the transfer device M1 (or M2) in the empty pallet state on the side of the elevator E first passes through the shortest distance as indicated by the solid arrow. Then, the pallet P1 on which the car to be unloaded is loaded is transferred to the elevator E. In this case, the transfer of the pallet P1 can be performed only by vertical feeding. Also, there is no need to make a detour before reaching Elevator E, so the delivery time is the shortest. When the pallet P1 is transferred to the elevator E1, the elevator E1 descends to the ground floor 1F, and from there, exits via the doorway 1. It should be noted that, in the case of warehousing, the operation is performed in the reverse order of the above, but it goes without saying that the warehousing time is also short in this case.

Next, a case where the vehicle is unloaded from the pallet indicated by the symbol P3 in FIG. 2 will be described. In this case, first move the pallet P4 as shown by the double-lined arrow, and then move it onto the pallet positioner M1 and simultaneously move the pallet.
P3 is moved as indicated by the double-lined arrow and transferred to the elevator E. This operation can be performed by combining the vertical transfer and the horizontal transfer of the pallet transfer device M. And since it moves to Elevator E in the shortest distance, the delivery time is also the shortest. It should be noted that when warehousing is performed in the reverse order of the above, it goes without saying that the warehousing time is also shortened.

In short, according to the present invention, the movement path of the shortest distance can be freely selected, and the pallet P can be sent by the pallet transfer device M only on the route of the shortest distance.
The loading and unloading time can be shortened considerably. Moreover, even if the storage layer is a three-dimensional hangar having a plurality of upper and lower storage layers, since the transfer device M of the elevator E can feed in both the vertical and horizontal directions, it is possible to utilize the quick storage / removal operation of all the storage layers. As a result, the performance of the three-dimensional hangar as a whole can be significantly improved.

Next, another embodiment of the present invention will be described.
FIG. 12 is a perspective view of the elevator E having a turning function, FIG. 13 is a plan view of the turning portion, and FIG. 14 is a sectional view of the turning diagram. In FIG. 12, reference numeral 40 denotes an elevator frame, a turning portion 41 is mounted in the center thereof, and an automobile mounting frame 42 is attached to the turning portion 41. The pallet transfer device M (not shown) is installed on the bottom surface of the vehicle mounting frame 42, and the pallet P is loaded on the upper surface thereof.

Referring to FIGS. 13 to 14, the structure of the swivel portion 41 will be described. 43 is a swivel drum mounted on the upper surface of the vehicle mounting frame 42, and a guide rail 44 having a U-shaped cross section is fixed to the outer periphery thereof. ing. A roller 45 rolling in the guide rail 44 is pivotally attached to the elevator frame 40, and the automobile mounting frame 42 is rotatably suspended. On the other hand, a chain or belt 47 is wound around the turning drum 43 and the speed reducer 46, and when the motor 48 is driven, the vehicle mounting frame 42 turns. When the turning type elevator E is used, there is an advantage that the direction of the automobile can be changed at the entry point.

Next, still another embodiment of the present invention will be described with reference to FIGS. In FIG. 15, PF is a fork-shaped pallet and EF is a fork-type elevator. The fork-shaped pallet PF is equipped with front wheel and rear wheel forks 52 and 53 that project laterally from the base frame 51, and has a vertical feed rail groove 54 and a horizontal feed rail groove 55 formed on the lower surface. .

The fork-type elevator EF is composed of a rectangular base frame 60 and a fork-shaped lift table 61.
The 61 also has forks 62,63 for the front and rear wheels. The forks 62, 63 and the forks 52, 53 of the pallet PF are put together. elevator
Jacks 64 are arranged at the four corners of the base frame 60 of the EF, and the jacks 64 are used to move the lifting platform 61 up and down. Although a screw type jack is shown in the figure, an arbitrary jack such as a hydraulic type or a link type may be adopted. Further, the raising and lowering wire ropes 34 are fixed to the four corners of the base frame 60 via the brackets 65, and further raising and lowering guide rollers 27 (see FIG. 16) are attached. Therefore, for example, when the wire rope 34 is hoisted and unwound by the hoisting mechanism 30 as shown in FIG. 9, the elevator EF moves up and down while being guided by the guide rollers 27.

The elevating mechanism is not limited to the one described above, but any mechanism can be used. Further, when the elevator EF is of a turning type, a turning mechanism including an elevator frame 40, a turning portion 41, an automobile mounting frame 42, etc. shown in FIGS.

As shown in FIG. 16, on the base frame 60 of the elevator EF, the pallet transfer device M including the vertical feed roller unit 3 and the horizontal feed roller unit 8 similar to that shown in FIG. 10 is installed. ing. Therefore, the fork-shaped pallet PF can be vertically or horizontally fed from within the elevator EF (or into the elevator EF). That is, the left side of FIG. 16 shows a state in which the lateral feed roller 11 of the lateral feed roller unit 8 is raised and is in contact with the lateral feed rail groove 55 of the fork-shaped pallet P, and the right side of the figure is the vertical feed roller unit 3. The vertical feed roller 4 is in contact with the vertical feed rail groove 54. In the former case, the fork-shaped pallet PF can be fed laterally, and in the latter case, it can be fed longitudinally.
Further, as described above, since the fork 52 (53) of the pallet PF and the fork 62 (63) of the lift 61 have a shape and a positional relationship with each other, the lift 61 is shown in a solid line in a raised position and an imaginary line. It is possible to move up and down between the elevator EF and the pallet PF without interfering with the pallet PF, and the vehicle can be transferred between the elevator EF and the pallet PF.

When the pallet PF of this embodiment is used, the vertical feed roller unit 3 is provided in every section of each storage layer.
Pallet transfer device M equipped with a horizontal feed roller unit 8
It goes without saying that the

Next, the warehousing operation in this embodiment will be described with reference to FIG. FIG. 1 (I) shows a state in which a car is loaded on the elevator EF and is raised (or lowered) to an arbitrary storage layer. The elevator EF is stopped at a position where the pallet transfer device M is at the same level as the storage room side pallet transfer device M, and the lift 61 is raised. Here, the pallet transfer device M on the storage room side is transferred onto the transfer device M on the elevator side.
The fork-shaped pallet PF is fed by the vertical feed roller unit 3 of.

FIG. 2 (II) shows a state in which the feeding is completed, and the pallet PF is located below the lift table 61. Then, the jack 64 is driven to lower the lifting platform 61. The vehicle is transferred to the fork-shaped pallet PF by the lowering of the lifting platform 61.

FIG. 3 (III) shows the operation of feeding the fork-shaped pallet PF by the vertical feed roller units 3 of the elevator-side pallet transfer device M and the storage chamber-side pallet transfer device M. When the pallet PF is moved to the storage room side pallet transfer device M, the vehicle is further stored in the appropriate storage room through the transfer path having the shortest distance. This operation can be performed in the shortest time for the same reason as the shipping operation shown in FIG.

The operations (I) to (III) were carried out by vertically feeding the pallet PF. However, this may be carried out horizontally by using the horizontally feeding roller unit 8, or horizontally and vertically. It is also possible to combine the above. In the case of the leaving operation, the operations may be performed in the reverse order of the above.

In the case of the present embodiment, the pallet PF does not have to be used while the elevator EF moves up and down, and the pallet PF only needs to circulate in each storage layer. In other words, the elevator EF can transport cars without using the pallet PF,
It is not necessary to carry an empty pallet each time of loading and unloading to prepare for loading and unloading, and the time required for forwarding empty pallets can be eliminated, so that the loading and unloading time can be further shortened as compared with the above embodiment.

Next, FIG. 18 is a plan view of a storage layer of a parking lot according to another embodiment of the present invention. In the case of the above-mentioned embodiment, the outer shape of the storage layer is a quadrangle, but the shape is not limited to this, and the outer shape may be such that a part is cut out as shown in FIG. Such a shape may be appropriate depending on the location conditions. The reference numerals in the figure indicate the same parts as those in the above-mentioned embodiment.

Although each of the above-described embodiments is applied to the parking lot, the present invention can be applied to a three-dimensional warehouse. In this case, if the pallet for automobiles is understood as a pallet for storing articles, the structure of the above-mentioned multi-story parking lot may be understood as it is as the structure of a multi-story warehouse.

[0035]

According to the present invention, although it is a horizontal circulation type three-dimensional hangar, it is possible to make the warehousing time much shorter than the conventional example.
