Description

  The present invention relates to an article and / or an article storage container (hereinafter referred to as “articles etc.”) between adjacent storage shelves and between a plurality of storage facilities arranged with a certain interval between storage facilities composed of a pair of adjacent storage shelves. It is related to a three-dimensional automatic warehouse that can be freely moved and can easily sort articles and the like.

  A typical three-dimensional automatic warehouse is equipped with storage shelves for articles etc. that are arranged in a grid pattern in the horizontal longitudinal direction and the vertical direction, and a storage surface in which the articles etc. of the storage shelves can be taken in and out is provided with a passage (space). A set of storage shelves arranged in two rows so as to be opposed to each other is set as one set, and a predetermined number of sets are arranged, and moving means such as articles are arranged in each space.

  There are various three-dimensional automatic warehouses depending on the difference in the means for moving such goods. For example, a three-dimensional object that can freely move articles in the horizontal longitudinal direction (X-axis direction) and vertical direction (Y-axis direction) of the storage shelf by moving the articles etc. using a stacker crane as a moving means. Automatic warehouses (for example, Patent Documents 1 to 3) are known. In addition, as a moving means, a traveling carriage is arranged at each stage in the Y-axis direction, and articles and the like can be moved in the X-axis direction of the storage shelves at each stage, and articles and the like in the Y-axis direction can be moved by an elevator. 3D automatic warehouse (for example, Patent Document 4 and Non-Patent Document 1).

As an example of the three-dimensional automatic warehouse using the former stacker crane, a stacker crane type three-dimensional automatic warehouse disclosed in Patent Document 2 is shown in FIG. In the three-dimensional automatic warehouse 80, storage shelves for storing articles and the like arranged in a grid pattern in the X and Y directions are arranged in L _n columns, L _n ′ columns, and L _{n + 1} columns. A stacker crane 81 is disposed in the space 88 between the storage shelves in the L _n ′ row and the L _{n + 1} row. The stacker crane 81 includes a crane mast 82, a crane carriage 83, a lower traveling rail 84, an upper traveling rail 85, an article mounting table 86, and the like. The mounting table 86 of the stacker crane 81 is provided with, for example, a telescopic arm 87 for transferring the storage racks between the mounting table 86 and the L _n ′ and L _{n + 1} columns. In this example, the stacker crane 81 installed in the space 88 moves the storage shelf in the XY-axis direction, that is, the movement of articles in the vertical and horizontal directions, and the storage shelf in the depth direction (Z-axis direction). It is possible to move. Then, carrying in / out of articles and the like to / from the storage shelf is performed by the carry-in / out device 89.

  In this example, the loading / unloading of articles and the like seems to be performed directly between the stacker crane 81 and the loading / unloading device 89. However, another stacker crane is provided via a temporary storage shelf. An example of carrying in / out between stacker cranes is also disclosed in Patent Document 3.

On the other hand, as an example of a three-dimensional automatic warehouse using the latter traveling cart, a three-dimensional automatic warehouse disclosed in Non-Patent Document 1 is shown in FIG. The three-dimensional automatic warehouse 90 includes L _n−1 , L _n , L _{n + 1} , and L _{n + 2} storage shelves for storing articles and the like arranged in a grid pattern in the X and Y directions, and the storage shelves L. during the _n-1 rows and _{L n} columns, each space 98 between the storage shelves _{L n + 1} columns and _{L n + 2} columns, and a traveling carriage 95 in each stage. The storage shelves L _n-1 and L _n , and the storage shelves L _{n + 1} and L _{n + 2 are} arranged with their storage surfaces facing each other, and provided in the space 98 between them in the X-axis direction. The traveling carriage 95 can reciprocate on the rail 94. _{L n-1} column and the _{L n} columns by the traveling carriage 95, _also for transferring the articles of each storage shelf of _{L n + 1} columns and _{L n + 2} rows.

  For example, the traveling carriage 89 is provided with an extendable arm (not shown), and exchanges with a storage shelf.

  Further, on both sides in the X-axis direction, carry-in devices 96 and carry-out devices 97 for loading / unloading articles etc. into / from the storage shelves are arranged, and articles etc. are placed between the respective storage shelves and the carry-in devices 96 and the carry-out devices 97. Elevators 91 that perform the delivery are installed corresponding to each space 98.

The movement of articles and the like between each storage shelf L _n−1 row, L _n row, L _{n + 1} row, L _{n + 2} row and the carry-in device 96 and the carry-out device 97 is carried by a loading table 92 for the items and the like provided in the elevator 91. And by the traveling carriage 95 via the temporary storage carriage 93 that delivers articles and the like provided on the storage shelves at each stage. In addition, when it is necessary to move between the storage shelves in the vertical direction, it is also possible to perform this through the elevator 91.

Accordingly, in the three-dimensional automatic warehouse 90 provided with the elevator 91 having the traveling carriage 95 and the article carrying platform 92 for the articles and the like, it is possible to move the articles and the like in the X and Y axial directions by such moving means, and Articles and the like in the Z-axis direction can be moved between opposing storage shelves such as L _n−1 and L _n rows, L _{n + 1} and L _{n + 2} rows facing each other.

Also in the three-dimensional automatic warehouse 90 provided with the traveling cart that reciprocates in the XY-axis direction in the space between the opposing storage shelves shown in FIG. 11, like the stacker crane type three-dimensional automatic warehouse 80 shown in FIG. In some cases, the backs of the storage shelves L _n and L _{n + 1} in FIG. 11 are connected and integrated.

As shown in FIGS. 10 and 11, in this type of three-dimensional automatic warehouse, since the stacker crane 81 and the traveling carriage 95 are arranged in the spaces 88 and 98 as moving means for moving articles and the like, L _{n− It} is possible to move articles and the like in the XY-axis direction of the storage shelves in each column such as _one column, L _n−1 ′ column, L _n column, L _n ′ column, L _{n + 1} column, L _{n + 1} ′, and the like. However, it is difficult to move articles etc. to the storage shelves facing the other spaces 88, 98 across the spaces 88, 98, etc.

For example, the stereoscopic automatic warehouse 80 shown in FIG. 10, it is difficult to move the articles or the like in position P _n of the storage shelves L _n columns to the position of the P _{n + 1} of the storage shelf of L _{n + 1} row. Further, in the three-dimensional automatic warehouse 90 shown in FIG. 11, the articles etc. at the position of P _n−1 of the storage shelf of the L _n−1 row or the position of P _n of the storage shelf of the L _n row are stored in the L _{n + 1} row. it is difficult to move to the position of the P _{n + 2} of the storage shelf of P _{n + 1} position and L _{n + 2} rows of storage shelves. That is, it is difficult to move an article or the like across a row or across a space (passage).

  Further, only one row of the space 88 is illustrated in the three-dimensional automatic warehouse 80 shown in FIG. 10, but like the three-dimensional automatic warehouse 90 shown in FIG. It is necessary to install a plurality of elevators 91 that relay between the temporary carriages 93 to the traveling carriage 95 corresponding to each space 98, and the number of elevators can be increased along with the addition of storage shelf rows in any three-dimensional automatic warehouse. Will also increase.

  As a basic configuration of the three-dimensional automatic warehouse of the present invention, an elevator interposed between a device for loading / unloading articles etc. and a plurality of storage shelf rows in a multi-stage configuration is moved so as to be orthogonal to each storage shelf row. Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing a three-dimensional automatic warehouse according to an embodiment of the present invention. In FIG. 1, the three-dimensional automatic warehouse 1 includes a multi-stage storage shelf such as an L _n−1 ′ column, an L _n column, an L _n ′ column, an L _{n + 1} column, an L _{n + 1} ′ column, an L _{n + 2} column, and the like. It is composed of an elevator (crane) 11 and a conveying device 2 for carrying in / out goods. The conveying device 2 for loading / unloading articles and the like includes loading / unloading units 21 and 22 for loading / unloading the articles 23 and the like to / from the storage shelf via the elevator 11. The elevator 11 has a car 111 attached to the lower part thereof and is movable in the Z-axis direction on one end side of each storage shelf. In addition, on both sides of the elevator 11, a loading / carrying table 12 for articles and the like is provided, and each loading / carrying table 12 can be moved up and down asynchronously.

In addition, FIG. 1 illustrates a configuration composed of storage shelf rows adjacent on the back side, such as L _n−1 ′ row and L _n row, L _n ′ row and L _{n + 1} row, L _{n + 1} ′ row and L _{n + 2} row, etc. A moving means (not shown) is provided in the space 8 serving as a conveyance path for the articles and the like between them to convey and move the articles to each storage shelf.

In addition, the storage shelves of the L _n-1 ′, L _n , L _n ′, L _{n + 1} , L _{n + 1} ′, and L _{n + 2} columns are basically a loading / conveying table for articles and the like of the elevator 11. 12, a temporary carrying table 131 used for delivery of articles and the like, and a storage shelf 132 for storing and storing articles and the like.

  The elevator 11 moves articles in / out by moving in the direction orthogonal to each storage shelf row, that is, in the Z-axis direction in FIG. It is possible to face any temporary placement carriage 131 on the YZ plane. Further, in addition to the movement of articles to be carried in / out, it is further characteristic that the elevator 11 can be moved so that the movement between the storage shelves on the YZ plane of the storage rack can be temporarily transferred. The point is that this can be achieved via the base 131. Arbitrary movement of the storage shelf on the XY plane is enabled between the temporary transfer table 131 and each storage shelf by the moving means arranged in each space 8. Therefore, by making the elevator 11 movable in the Z-axis direction, not only economically, such as reduction of equipment, but also goods can be freely moved in the XYZ-axis direction of the storage shelf, and functions can be improved. .

  The moving means arranged in the space 8 between the storage shelf rows is sufficient if it has a function of holding and moving articles and the like and a function of transferring between the mounting table and the shelf. For example, a stacker crane or a traveling carriage can be used as the moving means. In the case of a stacker crane, since the mounting table can be moved up and down in addition to the function of delivering articles and the like between shelves, the movement in the XY plane can be freely performed. Further, in the case of a traveling carriage, the vehicle is disposed so that it can travel via a rail or the like for each step in the vertical direction. The embodiment shown in the following FIG. 2 and the like will be described using an example in which a traveling carriage is used, but it does not exclude moving means such as a stacker crane.

  In FIG. 1, in the three-dimensional automatic warehouse 1, an example in which the elevator 11 and the transport device 2 are provided on the near side in the X axis direction is shown, but the present invention is not limited to this, and the front and rear in the X axis direction An elevator 11 and a transfer device 2 that are movable at the ends (front and back sides), respectively, may be provided, and carry-in and carry-out may be separated in the front-rear direction. Moreover, the elevator 11 which can be moved to the near side in the X-axis direction may be arranged, and a conventional fixed elevator may be installed on the rear side (back side) corresponding to each space 8, and vice versa. A movable elevator may be installed on the rear side (back side) and a fixed elevator on the front side corresponding to each space 8.

  Further, regarding the moving structure of the elevator 11 in FIG. 1, a rail may be arranged on the floor surface instead of the car 111 and moved on the floor. Considering the occurrence of the above, movement by the car 111 is preferable.

FIG. 2 is a plan view of a three-dimensional automatic warehouse in which moving means are arranged between storage shelves according to an embodiment of the present invention. The basic configuration of the three-dimensional automatic warehouse in FIG. 2 is the same as that in FIG. 1, but in the configuration of each storage shelf, multi-stage storage shelves L _n-1 column and L _n column, L _{n + 1} column, L _{n + 2} column, L _{n + 3} The row and the Ln _{+ 4} row constitute the storage facility as one set each. Accordingly, in this case, the number of shelves may be increased by one set.

In FIG. 2, storage shelves as means for moving articles and the like between storage shelves such as L _n−1 and L _n , L _{n + 1} and L _{n + 2} , L _{n + 3} and L _{n + 4,} facing each other with a space 8 therebetween. The traveling cart 10 which moves on the rail 14 provided in the X-axis direction is illustrated. In a multi-stage storage shelf, the traveling carriage 10 and the rail 14 are installed in each stage.

  In FIG. 2, carrying in / out of articles and the like to / from the storage shelf is performed via a carry-in / out device (not shown) and a movable elevator 11. The movable elevator 11 moves in the Z-axis direction indicated by the arrow on the lower side of the storage shelf, thereby placing the transfer carrier 12 of the elevator 11 and any temporary storage platform 13 above, below, left, and right of the storage shelf row. Can be butt-connected.

  Therefore, installation equipment can be saved by installing a movable elevator as compared to a conventional elevator that is fixedly installed corresponding to the space of each storage shelf row.

Furthermore, the elevator 11 can be attached to any temporary storage table 13 such as each storage shelf row, L _n−1 row, L _n row, L _{n + 1} row, L _{n + 2} row, L _{n + 3} row, L _{n + 4} row, etc. Since the mounting / conveying table 12 can be connected, it is possible to move between the storage shelf rows, in particular, between the storage shelves across another space 8. That is, in the self-supporting automatic warehouse shown in FIG. 2, movement or replacement of articles in the X-axis direction between storage shelf rows facing each space 8 can be performed by the traveling carriage 10, and articles in the Y-axis direction. And the like can be moved by moving the mounting / conveying table 12 of the elevator 11 up and down, and the movement of articles and the like between the storage shelf rows (in the Z-axis direction) can be performed by moving the elevator 11. This is possible by going through the table 12 and the temporary transfer table 13. Therefore, articles can be freely moved between any storage shelves in XYZ.

  In addition, the connection between the mounting transport table 12 of the elevator 11 and the arbitrary temporary transport table 13 of the storage shelf row does not mean a tight connection, and articles and the like mounted between the transport tables move (transfer). It is sufficient to align with a possible interval. The same applies to the configurations of the embodiments in other drawings described below.

FIG. 3 is a plan view of a three-dimensional automatic warehouse according to an embodiment of the present invention in which moving means is arranged between storage shelves that are adjacent storage shelves on the back side. / Corresponds to a plan view omitting the part of the unloading device. While the three-dimensional automatic warehouse shown in FIG. 2 has a multi-stage storage facility composed of a pair of multi-stage storage shelves, FIG. 3 shows the L _n and L _n ′ columns of storage shelves. , L _{n + 1} column and L _{n + 1} ′ column are adjacent to each other on the back surface.

Also in FIG. 3, storage is performed between the L _n−1 ′ column and the L _n column, the L _n ′ column and the L _{n + 1} column, and the L _{n + 1} ′ column and the L _{n + 2} column that are opposed to each other with the space 8 as a moving unit. A traveling carriage 10 that moves on a rail 14 provided in the X-axis direction of the shelf is provided. In a multi-stage storage shelf, the traveling carriage 10 and the rail 14 are installed in each stage.

  As in FIG. 2, also in FIG. 3, the carry-in / out of articles and the like to / from the storage shelf is performed via a carry-in / out device (not shown) and the movable elevator 11. The movable elevator 11 moves in the Z-axis direction on the lower side of the storage shelf in the figure, so that the mounting conveyor table 12 of the elevator 11 and any temporary storage platform 13 above, below, left, and right of the storage shelf row are connected to each other. it can.

  Therefore, installation equipment can be saved by installing a movable elevator as compared to a conventional elevator that is fixedly installed corresponding to the space of each storage shelf row.

Furthermore, for any temporary storage table 13 such as each storage shelf row, L _n−1 ′ row, L _n row, L _n ′ row, L _{n + 1} row, L _{n + 1} ′ row, L _{n + 2} row, etc. Since the mounting carriage 12 of the elevator 11 can be connected, it is possible to move between storage shelf rows, particularly between storage shelves across another space 8. That is, in the self-supporting automatic warehouse shown in FIG. 3, it is possible to move or replace articles in the X-axis direction between the storage shelf rows facing each space 8 with the traveling carriage 10, and articles in the Y-axis direction. And the like can be moved by moving the mounting / conveying table 12 of the elevator 11 up and down, and the movement of articles and the like between the storage shelf rows (in the Z-axis direction) can be performed by moving the elevator 11. This is possible by going through the table 12 and the temporary transfer table 13. Therefore, articles and the like can be freely moved between arbitrary storage shelves in XYZ.

  FIG. 4 is a three-dimensional automatic warehouse in which moving means are arranged between storage shelves that are adjacent to each other on the back according to an embodiment of the present invention, and transports articles and the like to a specific storage shelf that is adjacent on the back. It is a top view of the three-dimensional automatic warehouse which provided the conveyance mechanism to perform.

FIG. 4 shows a configuration in which the storage shelf rows L _n and L _n ′, and L _{n + 1} and L _{n + 1} ′ are adjacent to each other on the back side, similar to the three-dimensional automatic warehouse shown in FIG. 3. 4, as a means for moving articles and the like between the L _n−1 ′ and L _n columns, the L _n ′ and L _{n + 1} columns, and the L _{n + 1} ′ and L _{n + 2} columns facing each other across the space 8. A traveling carriage 10 that moves on a rail 14 provided in the X-axis direction of the storage shelf is provided. In a multi-stage storage shelf, the traveling carriage 10 and the rail 14 are installed in each stage. In addition, loading / unloading of articles and the like into / from the storage shelf is performed via a loading / unloading apparatus (not shown) and the movable elevator 11. The movable elevator 11 moves in the Z-axis direction as indicated by the arrow on the lower side of the storage shelf, so that the temporary transfer carrier 12 on the top and bottom and left and right of the storage shelf row can be moved. 13 can be butt-connected.

Further, FIG. 4 is characterized in that a transport mechanism A in the Z-axis direction is provided in a set of specific storage shelves adjacent on the back side. This transport mechanism A, L _n columns and L _n can be more easily moved in the Z-axis direction of the article, such as between _'column, L n _{+ 1} columns and L _{n + 1'} storage shelf adjacent the back of the column. Although this conveyance mechanism A is not specifically limited, It can be comprised with various conveyors.

  Also in FIG. 4, movement and replacement of articles and the like in the X-axis direction between the storage shelf rows facing each space 8 can be performed by the traveling carriage 10, and movement and replacement of articles and the like in the Y-axis direction can be performed by the elevator 11.
