Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage facility using a vertical and horizontal traveling carriage for efficiently storing luggage.

[0002]

2. Description of the Related Art Conventional three-dimensional automatic storage equipment adopts a stacker crane system or a dolly system in order to maximize the use of a predetermined storage area. The former stacker crane method is an effective method for efficiently loading and unloading various types of stacker cranes, because a rack is installed so as to face the stacker cranes when transferring and receiving luggage. Has the drawback of becoming a dead space.

The latter dolly system is suitable for storing a small number of products in a large amount because it has the advantage of requiring less dead space because the dolly passes under the luggage. Since the dolly moves to and from where the goods are put in and taken out, it becomes difficult to meet the shipping request when the variety of products increases.

For example, as shown in FIG. 2, track 01
Luggage 02 carried in from the
Traverser 0 for transporting in the horizontal direction at 3
4 is conveyed in the vertical direction to reach the storage rack 05. As shown in FIG. 12, the storage rack 5 is configured such that rails 06 having a U-shaped cross section are arranged on the left and right sides, and the left and right wheels 08 of the dolly 07 are inserted into the rails 06 to run.

Therefore, at the time of warehousing, as shown in FIG. 13, there is no load 0 from the warehousing traverser 04 onto the dolly 07.
2 is transferred and the dolly 07 is run from the left side to the right side in the drawing to be stored in the storage rack 05 in order from the right end in the drawing. Further, at the time of unloading, as shown in FIG. 14, by running the dolly 07 from the left to the right in the drawing, the luggage 02 is transferred and carried out from the right end in the drawing to the unloading traverser 09 in order.

Further, as a first packing function, as shown in FIG. 15, the dolly 07 is run from the left side to the right side in the drawing to load the packages 02 in order from the right end in the drawing. In this way, in the dolly method, the parcels 02 are stored in columns, so that if the articles in each row are not the same, then the shipment cannot meet the shipping request.

[0007]

When storing, for example, a beverage product in a three-dimensional storage facility, there is a small number of products in the related art, and the problem is how to store a large amount of the same volume. Therefore, the dolly method is useful. Although it was a means, in recent years, even one kind of product has tended to be in cans, bottles, plastic containers, etc., and also in diversification in size and large variety and small capacity. Therefore, the stacker crane system is widely used, but as described above, there are many dead spaces and the storage efficiency is poor.

[0008] Further, due to the recent tendency, mixed loading in which multiple types of products are simultaneously placed on one pallet and shipped is demanded, and the same storage is required because it is desired to change the number of products to be stored depending on the season. Free design of storage layout in equipment is required. The present invention has been made in view of the above-described conventional art, and an object of the present invention is to provide a storage facility that allows a carrier to travel vertically and horizontally to efficiently store luggage.

[0009]

An object of the present invention to achieve such an object is to vertically install a plurality of vertical columns and horizontally mount a traveling rail having an intersection between the vertical columns, while the traveling rail is installed. It is characterized in that a load receiving arm is attached to the vertical column at a position slightly higher than the height of the vertical and horizontal traveling carriage that travels vertically and horizontally on the rail. Here, in the vertical / horizontal traveling carrier, at least one traveling wheel is provided on a carriage main body so as to be rotatable, and a speed reducer, a motor and a brake are attached to at least one of the traveling wheels, and at least the traveling rail is guided vertically and horizontally. Characterized in that two or more guide rollers are attached to the transport carriage,
An elevating table for transferring luggage to and from the arms is provided on the trolley body so as to be vertically movable.

[0010]

According to the present invention, unlike the conventional dolly system in which the traveling rail on which the carrier truck travels is also used as the arm for holding luggage, since the traveling rail and the arm are functionally separated, movement of the carrier truck is performed. Has become a structure that is not constrained in one direction. Further, by mounting a traveling rail having an intersection between a plurality of vertical pillars in the horizontal direction, it becomes possible for the carriage to travel in two horizontal directions, that is, in the vertical and horizontal directions of the X axis and the Y axis.

The vertical and horizontal traveling carriage is equipped with swingable wheels on the main body of the carriage, so that it can travel in both the X-axis direction and the Y-axis direction, and at least one of the wheels is a speed reducer on the wheels themselves. Since it is equipped with a motor and brakes, it can run on its own, and since the guide rollers that guide at least two or more traveling rails in the vertical and horizontal directions are attached to the main body of the carriage, the crossing on the traveling rails in the X-axis and Y-axis directions It became possible to run in either direction. The trolley body has a lifting table that can be lifted and lowered, so that luggage can be transferred to and from the arms.

Running rails 13, 13 ', 14, 14'
As shown in FIG. 5, is composed of a traveling portion 17, rising portions 18 and reinforcing portions 19 formed on both sides of the traveling portion 17. The running portion 17 is a portion on which the wheels 32a to 32d of the XY dolly 30 are placed, and the rising portion 18 is a portion to receive and guide the guide rollers 51a to 51d. The rail itself is relatively thin in order to reduce the weight of the rail structure, but a reinforcing portion 19 is provided to maintain the required strength.

Further, as shown in FIG. 4, a cargo receiving arm 15 is attached to the vertical column 12 so as to project in the horizontal direction. Therefore, the luggage 1 supported by this arm 15
It is possible for the XY dolly 30 to travel on the traveling rail 8 while diving under 6. As shown in FIG. 4, the cargo receiving arm 15 is located at a position slightly higher than the height of the XY dolly 30 from the traveling rail 8 and holds the luggage 16 at the four corners in the front, rear, left and right in each storage space.

As shown in FIGS. 6 to 9, the XY dolly 30 is a trolley capable of traveling in two directions, a vertical direction and a horizontal direction, and is provided with a lifting table 41 for transferring the load 16. There is. That is, the wheels 32 are provided at the four corners of the carriage main body 31.
a, 32b, 32c, 32d are arranged, and these wheels 3
As shown in FIG. 10, 2a, 32b, 32c, and 32d are pivotally supported by brackets 36a to 36d at bearings 37a to 37d at four corners of the bogie body 31 so as to be rotatable.

The wheels 32a to 32d are mounted on the traveling rail 8 and support the carriage main body 31, and in the present embodiment, urethane rubber is attached to the outer peripheral surfaces of the wheels 32a to 32d. Each wheel 32a, 32b, 32
c and 32d are motors 33a, 33b, 33c and 33d incorporating reduction gears (not shown) and a brake 34.
a, 34b, 34c, 34d are attached.

Therefore, by transmitting the rotations of the motors 33a to 33d to the wheels 32a to 32d through the speed reducer, the carriage main body 31 can travel on the traveling rail 8 and the brakes 34a to 34d can be used to drive the trucks. You can stop at a position. The motors 33a to 33d and the brakes 34a to 34d are not necessary for all the wheels 32a to 32d, but may be provided to at least one of the wheels.

Further, each wheel 32a, 32b, 32c, 3
One ends of turning cylinders 35a, 35b, 35c and 35d are pivotally attached to brackets 36a to 36d that pivotally support 2d, and the other ends of the turning cylinders 35a to 35d are connected to the carriage main body 31. Turning cylinders 35a-3
5d is an electrically expandable / contractible cylinder. By expanding and contracting the turning cylinders 35a to 35d, as shown in FIGS. 6A and 6B, the wheels 32a together with the motors 33a to 33d and the brakes 34a to 34d. ~ 32d can be swiveled about 90 °.

Therefore, it is possible to travel the XY dolly 30 in the vertical and horizontal directions by arbitrarily selecting the directions of the wheels 32a to 32d. Further, traveling guide rollers 51a, 51b, 51c, 51d are arranged at four corners of the carriage main body 31, and these traveling guide rollers 51a to 51d are
As shown in FIG. 11, the XY dolly 30 has a structure in which the XY dolly 30 accurately moves straight by guiding the rising 18 of the traveling rail 8.

Further, a lift table 41 is provided on the carriage main body 31 so as to be lifted and lowered so as to transfer the luggage 16. That is, the bogie body 31 includes two lifting shafts 45, 4
8 is rotatably supported, and the lifting shaft 45 has an arm 4
9c, 49d, the arms 49a, 4 on the lifting shaft 48.
While 9b is fixed, supporting metal fittings 50a, 50b, 50c and 50d are fixedly mounted on the lower surface of the lifting table 41, and these arms 49a to 49d and supporting metal fittings 50a to 50d are respectively pin-coupled.

The lifting table 41 has a horizontal upper surface on which the luggage 16 can be placed. It is omitted in FIGS. 6A and 6B. The lifting shafts 45, 48 are further provided with arms 44, 4
7 are fixed to each other, and the ends of the connecting rod 46 are pin-connected to the arm 44 and the arm 47, respectively. 42 is fixed, and the ends of the connecting rod 43 are pin-connected to the arms 42 and 44, respectively.

Therefore, when the lifting motor 40 is driven to rotate the arm 42, power is transmitted through the connecting rod 43, so that the lifting shaft 45 rotates integrally with the arm 44,
At the same time, power is transmitted via the connecting rod 46, so that the lifting shaft 48 rotates integrally with the arm 47. Therefore, the arms 49c and 49 are coaxially integrated with the lifting shafts 45 and 47.
The d, 49a, and 49b rotate, and the lifting table 41 moves up and down while maintaining the horizontal state together with the support fittings 50c, 50d, 50a, and 50b that are pin-connected to the d and 49a.

For this reason, as shown in the lower part of FIG. 4, the XY dolly 30 is run on the running rail 8 while the lifting table 41 on which the luggage 16 is placed is raised, so that the arms 15 are shielded. The storage space can be passed through without being damaged. Further, as shown in the upper part of FIG. 4, the luggage 16 can be transferred onto the arm 15 by lowering the elevating table 41 in a predetermined storage space. Only the XY dolly 30 can be run on the running rail 8.

In the storage facility of the present embodiment having the above-mentioned structure, the luggage 16 is carried in as follows. First, the cargo entering from the storage line 6 composed of a conveyor or the like is carried to a predetermined shelf by a storage elevator 7 such as a vertical conveyor or a stacker crane, and then the XY dolly 30 waiting on the traveling rail 8 is provided. Is carried and stored in a predetermined storage space.

On the contrary, in the case of warehousing, it is passed from the predetermined storage location through the traveling rail 8 and is carried out through the warehousing elevator 9 and the warehousing line 10 similar to the warehousing elevator 7. In this embodiment, there is a frontage of 15 columns and 15 rows and 10 shelves.
The number of tiers can store 2250 pallets, which is equivalent to the conventional dolly system. If the stacker crane system is used under the same conditions, 5 rows,
In other words, since it is necessary to use five lanes as a passage for the stacker crane, only one pallet can be stored.

Therefore, in the present invention, 1500 pallets to
This means designing the storage layout freely among the 2250 pallets. In this embodiment, columns G and N are lanes functioning only for transportation, and 7 rows H to
The same lane is used for the 5 frontages in the L row, so the actual storage space is 1900 pallets. In such a storage layout, the packages with the largest number are stored in the rows A to C, and the packages with the smallest number are stored in the rows M and O.

The storage layout of this embodiment is an example of the present invention, and it is not necessary to have all 10 storage stages as such a storage layout, and different layouts can be used depending on the stage. It can be easily stored according to the same equipment. Further, not all of the 10 steps of loading and unloading work are performed fully, and in this case, the XY dolly 30 is changed using the elevators 7 or 9 in accordance with the significant difference in the loading and unloading work amount. You can also do the work.

[0031]

As described above concretely on the basis of the embodiments, the present invention functionally separates the traveling rail on which the carrier truck travels from the arms for holding luggage and has an intersection. A traveling rail is provided so that the transport cart can travel vertically and horizontally. Therefore, compared to the conventional dolly method, not only can the luggage be stored over the entire rack surface as in the conventional case, but also various types of luggage can be stored.
It is possible to perform shipments that meet arbitrary shipping requirements. Further, as compared with the conventional stacker crane system, not only can the load of each pallet be put in and out as in the conventional stacker crane system, but also a large amount can be stored in the same storage volume. As described above, according to the present invention, in the three-dimensional storage facility, the storage layout can be appropriately changed even for each shelf, and it is possible to easily cope with the change in the quantity and type of the stored load depending on the season and time. You can
