[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelving device for an automatic warehouse.

[0002]

2. Description of the Related Art An automatic warehouse is a stacker crane type in which a movable carriage is provided with a lift that can be raised and lowered, a type in which the movable carriage only travels horizontally on rails, or a lift in which the movable carriage is only moved up and down. There are types that are configured in a shape. Among these, as a rack device in an automatic warehouse of a type in which a moving carriage only travels horizontally on rails, Japanese Utility Model Publication No. 6-22642 discloses that the rails are fixed to front columns that are erected at appropriate intervals and the rails are sandwiched. A rear support frame that extends parallel to the rail is arranged at the rear support column that forms a pair with the front support column on the opposite side across the traveling path of the moving carriage, and in the depth direction in plan view between the rail and the rear support frame. The extending strip-shaped shelf boards are arranged at appropriate intervals, and each shelf board is fixed to the rail and the rear support frame with bolts or the like, and the adjacent shelf boards form a rectangular container (a box or a box). A structure adapted to support the side edge of the tray is disclosed.

That is, in this conventional shelving device, a space is provided between adjacent shelves.

[0004]

In the case of a type in which luggage is stored in a container, such as the automatic warehouse of the above publication, since the container has sufficient strength, a space is provided between adjacent shelf boards. You may form. However, the means for storing and storing the luggage in the container has the drawbacks that the utilization efficiency of the space is low and it takes time to take the luggage in and out of the container. For this reason, recent automated warehouses are required to have a function of directly loading luggage of different sizes on a shelf without using a container. For that purpose, the entire bottom surface of the shelf is covered with a shelf board. There is a need.

In this case, the lateral distance between the columns supporting the shelves and the rails (the distance along the traveling direction of the moving carriage) needs to be as long as possible from the viewpoint of storage efficiency.
The width of the shelf board has a certain limit in terms of processing and carrying. Therefore, a plurality of shelves are arranged in parallel between the pair of columns adjacent to each other on the left and right. In other words, one storage area is composed of a plurality of shelves.

[0006] On the other hand, a transfer device for a movable carriage generally has a structure in which moving frames that move forward and backward toward the inside of the shelf are provided on both sides of the load carrying portion, and at the end of the moving frame. By moving the moving frame forward and backward while the picker provided is applied to the luggage, the luggage is transferred between the shelf and the moving carriage, and therefore the moving carriage also moves to the shelf. It is necessary to provide partitions according to the intervals between the frames.

According to the present invention, it is possible to reduce the manufacturing cost in a shelf device in which a plurality of shelves are lined up and mounted between columns and a storage area composed of a plurality of shelves is partitioned by a partition member. The purpose is to

[0008]

In order to achieve this object, the present invention provides: "A front support post located near the traveling path of the moving carriage and a traveling path of the moving carriage on one or both sides of the traveling path of the moving carriage. A plurality of pairs of rear columns, which are located apart from each other, are erected at appropriate intervals along the traveling direction of the moving carriage, and a front support frame is provided between the adjacent front columns, and between the adjacent rear columns. A rear support frame is horizontally mounted on each of the racks, and a plurality of shelves are installed side by side between the front and rear support frames, so that the part between adjacent pairs of columns becomes one storage area. In the device, each of the shelves is set to have the same frontage dimension, and each of the shelves is placed on the front-rear support frame so as not to be displaced back and forth, and engaged with both side edges along the depth direction of each shelf. While making holes, overlap the partition members while straddling the side edges of the adjacent shelf plates. Partition members are also arranged at the parts located at both ends of the storage area, and half of the partition member with the longitudinal center line sandwiched therebetween is overlapped on the side edge of the shelf plate, and the partition member is provided with engaging holes of the shelf plate. An engaging claw that fits and engages so that it cannot be pulled out vertically is provided so as to project downward.Furthermore, partition members located at both ends of the storage area are brought into contact with the front and rear columns or the horizontal rail member mounted between the front and rear columns. Or it is made to approach. "

[0009]

With this structure, since the adjacent shelves are in the same state as when they are connected to each other via the partition member, one shelving board constituting one storage area is one sheet. It becomes the same state as the plate-like connection, and as a result, the shelf device can have a sturdy structure without screwing the shelf plates one by one.

By the way, when one storage area is composed of a plurality of shelves, the side surfaces of the shelves located at both ends of the storage area are brought into contact with the support columns, in other words, one storage area is covered by the shelves without gaps. It is conceivable to cover it and partition the storage area with a partition member in that state. In that case, it is desirable to arrange the partition member at a position inside the storage area in a state of straddling the adjacent shelf plates from the viewpoint of effective use of space.

On the other hand, in order to secure a space for moving the moving frame in the moving carriage, it is necessary to provide partition members also at both ends near the supporting column, and when the shelf boards are arranged so as to hit the supporting column without any gap, Since the partition member located at the end of the storage area entirely overlaps the side edge of the shelf board,
The lateral width dimension of the shelf located at the end must be made larger than the lateral width dimensions of other shelf boards by half the lateral width dimension of the partition member, and the mounting position of the partition member must be changed.

Therefore, if the shelves are arranged without gaps between the adjacent columns, it is necessary to manufacture a plurality of kinds of shelves, which increases the manufacturing cost. On the other hand, according to the present invention, the partition member at any position,
Since each half sandwiching the center line overlaps the side edge of one shelf board, only one kind of each shelf board and partition member is required. In this case, since there is a gap between the shelf board and the support at the end of the storage area, half of the partition members located at the end of the storage area overhang the center line from the shelf. However, since the engaging claws of the partition member are fitted in the engaging holes of the shelf plate in a non-removable manner, the partition member does not fall off.

Therefore, according to the present invention, in a shelf device in which one storage area is composed of a plurality of shelves and is partitioned by a plurality of partition members, each of the shelves and partition members is of one type. Therefore, the manufacturing cost can be reduced. Further, according to the second aspect, the shelf plate can be attached by a very simple procedure of supporting the shelf plate by the front and rear partition members and then inserting the partition member into the front opening groove of the rear support frame. Not only can the labor for assembling the shelving device be reduced, but also the shelf plate, the rear support frame, and the partition member will be in a state of being integrally combined, so that there is an advantage that the strength can be improved.

Pickers 14 are provided at both ends of the second moving frame 13 so as to be horizontally rotatable in the direction of the luggage placement section 10. The picker 14 is driven by a driving unit such as a motor or an electromagnetic solenoid built in the second moving frame 13. When the picker 14 is laterally projected while the second moving frame 13 is greatly advanced, and the second moving frame 13 is retracted in this state, the luggage W is pulled out from the shelf 3 to the moving carriage 1. On the contrary, mobile trolley 1
The loader W is transferred from the moving carriage 1 to the shelf 3 by projecting the picker 14 sideways with the load W placed on it and advancing the second moving frame 13 to push the load W with the picker 14 in that state. be able to.

Next, the structure of the shelf 3 will be described with reference to FIGS. FIG. 3 is a plan view of the shelf 3. The shelf 3 is a plurality of shelf plates 16 formed of a metal plate in a shallow box shape with a downward opening.
Is equipped with. For example, as shown in FIG. 4 (A) and FIG.
A front foot piece 16a having an L-shaped cross section is provided at the front edge of each shelf 16 so as to project downward, while the rail 2 has the shelf 16 described above.
Is formed with a step portion 2a that supports the front foot piece 16a in a state in which it cannot be displaced forward. In the present embodiment, the rail 2 also serves as a front support frame that supports the front edge of the shelf plate 16.

As shown in FIGS. 4 (B) and 6, the rails 2 are fixed to the front faces of the front columns 17 adjacent to each other with bolts 18. The rear end edge of each shelf 16 is supported by a rear support frame 21 made of a metal plate extending parallel to the rail 2. The rear support frame 21 is also set to have the same length as the rail 2, as shown in FIG.
As shown in (B), the end of the bolt 1
It is concluded with 8. The front and rear columns 17 and 22 are erected at regular intervals along the traveling direction of the mobile trolley 1, and a pair of adjacent columns 17 and 22 forms one storage area 3a, and each storage area 3a has a space. A plurality of shelf boards 16 are arranged side by side.

As shown in FIGS. 4A and 7, the rear support frame 21 has a front opening groove 23 that opens toward the rail 2.
Is formed, and the rear end edge of the shelf 16 is inserted into the front opening groove 23. In this case, an upright standing piece 21a is formed on the front end edge of the front opening groove 23 in the rear support frame 21, while a rear foot piece 16b having an L-shaped cross section is formed on the rear end edge of the shelf board 16. The rear leg piece 16b is supported by the standing piece 21a of the front opening groove 23. The shelf 16 is held by the rear support frame 21 so as not to be displaced backward.

The front opening groove 23 of the rear support frame 21 has a gap 2 between the upper surface of the rear support frame 21 and the upper surface of the shelf plate 2 with a certain distance.
4 is set to such a height that the gap 24
, The rear end edge of the partition member 25 that overlaps and overlaps with both of the adjacent shelves 16 is inserted in a tight manner, whereby each of the shelves 16 is held in a vertically immovable state.

On the upper end of the rear support frame 21, a stopper piece 21b for preventing the luggage W from falling is provided so as to project upward. As shown in FIG. 4 (A) and FIG. 5 (A), the partition member 25 is formed so as to extend long along the depth direction of the shelf 3, and the luggage W is laterally offset on both longitudinal edges thereof. Guide part 2 protruding upward to prevent
5a is formed so as to extend over the entire length, and the rear end portion of this guide portion 25a is inserted into the gap 24 in a state in which it cannot move vertically. The front end portions of both guide portions 25a are inclined toward the longitudinal center line so as to have a C shape in a plan view.

As shown in FIGS. 4 (A) and 5, the lower surface of the partition member 25 at a plurality of locations along the longitudinal direction has hook-like shapes extending laterally in the direction of the center line of the partition member 25. The engaging claws 26 are cut and raised one by one. On the other hand, an engaging hole 27 corresponding to the engaging claw 26 is formed in the side edge of each shelf plate 16. This engaging hole 27 is
The wide portion 27a into which the engaging claw 26 can be vertically fitted and disengaged, and the engaging claw 2
6 is composed of a narrow portion 27b which cannot be removed. By inserting the engaging claw 26 into the wide width portion 27a, the partition member 25 is superposed on the shelf board 16, and in that state, the partition member 25 is slid toward the front opening groove 23 of the rear support frame 21. The rear end edge of the guide portion 25a of the member 25 is fitted into the front opening groove 23 of the rear support frame 21, and the engaging claw 26 moves to the narrow width portion 27b of the engaging hole 27 to be adjacent to the partition member 25. The three parts with the shelved board 16 are connected to each other.

By making the groove width of the narrow width portion 27b of the engaging groove 27 larger than the plate thickness of the engaging claw 26 to some extent, the narrow width portion 27b of the engaging groove 27 extends along the frontage direction. It is set so that it can move slightly. Figure 5 (A)
As shown in (C), each engaging claw 2 of the partition member 25
A dowel 28 extending obliquely forward is cut and raised at a portion in front of 6 so as to project downward. When the partition member 25 is fully slid toward the rear support frame 21,
As shown in (B), the dowel 28 is fitted and engaged with the front end edge of the engagement hole 27 in the shelf board 16, and the partition member 25 is held so as not to come out forward.

The shelves 16 and the partition members 25 are of the same type, and as shown in FIG.
On the side edge of the shelf 16 located at the end of a, columns 17, 2
The partition member 25 is attached in a state of being in contact with or close to the side surface of No. 2. Since there is only one type of each shelf 16 as described above, the shelf 16 located at the end of each storage area 3a
Between the column and the columns 17 and 22, there is a gap of half the width of the column 25. In other words, the partition member 25 located at the outermost end of the storage area 3a overlaps the shelf plate 16 only on one side across the center line, and in that state, the engaging claw 26 cannot be removed from the engaging hole 27. It is fitted and engaged.

Therefore, each shelf 16 has left and right columns 17, 22.
The columns 25 are held so that they cannot be laterally displaced from each other, and the columns 25 located at both ends of the storage section 3a do not fall off. As shown by the chain double-dashed line in FIG. 3, both moving frames 12 and 13 of the moving carriage 1 are set so as to move back and forth in the shelf 3 at a position above the partition member 25. Therefore, the shelf 16
Even if the luggage on the
In the next transfer operation, the moving frames 12 and 13 are the luggage W.
There is no hit.

In mounting the shelf board 16 in the above construction, first, the rear end edge of the shelf board 16 is inserted into the front opening groove 23 of the rear support frame 21, and then the front end edge is set on the step portion of the rail 2. 2a, and then placed, and then FIG.
As shown in (B), the partition member 25 is slid toward the rear support frame 21 in a state of being in contact with the upper surface of the shelf board 16.
This is an extremely simple procedure. Therefore, the shelf frame 4 can be assembled efficiently.

Further, since the rail 2 and the rear support frame 21 are made of a metal plate, if the wall thickness is thin, an arrow A in FIG.
As shown in FIG. 3, the rail 2 can be easily bent and deformed about the axis, but in the present invention, the rail 2 is fitted with the front end edge of the shelf 16 tightly with the step portion 2a of the rail 2. The rear end edge of the rail 2 and the rear end edge of the partition member 25 are fitted into the front opening groove 23 of the rear support frame 21 while being prevented from being deformed so as to be twisted about the axis, Since the rear support frame 21 is prevented from being deformed so as to bend around its axis, the rail 2 and the rear support frame 21 are prevented.
The strength of the shelf 3 can be improved without increasing the thickness.

Furthermore, since the shelf plate 16, the partition member 25, and the rear support frame 21 are in a state of being connected to each other, the strength of the shelf frame 4 can be further improved. Further, since the rear edge of the shelf board 16 is fitted into the rear support frame 21, the flexure deformation of the rear foot piece 16b and the rear foot piece 16b of the shelf board 16 is used to attach the shelf board 16 without play. You can

Since it is sufficient to manufacture each of the shelves 16 and the partition member 25 one by one, the manufacturing cost can be reduced and the labor for assembling can be reduced. As in the embodiment, when the engaging claw 26 is configured so as to be able to move slightly in the narrow width portion 27b of the engaging groove 27 along the frontage direction, the lateral width dimension of the shelf 16 and the left and right engaging claws of the partition member 25. Even if there is a processing error in the space dimension between the 26, there is an advantage that the processing error can be absorbed and the shelf board 16 can be reliably attached. The engaging claw 26 may be formed so as to extend in the direction of the rear support frame 21.

In the above embodiment, the partition member 25 directly abuts on the front and rear columns 17 and 22, but the partition member 2
5 may be applied to a reinforcing cross beam member or a brace mounted between the front and rear columns 17 and 22. The above embodiment was applied to the automatic warehouse of the type in which the moving carriage travels only horizontally on the rail, but the present invention is of the stacker crane type automatic warehouse or the lift type that only moves up and down. It goes without saying that the present invention can also be applied to other types of automated warehouses, such as an automated warehouse of a type in which luggage is transferred to a shelf by a mobile trolley.
