Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to warehouse equipment that is equipped with shelves and a loading/unloading device for loading and unloading loads onto and from the shelves, and is capable of handling loads of different sizes.

Conventional technical warehouse equipment that handles loads of different sizes is disclosed, for example, in Japanese Patent Application Laid-open No. 48-2673 and Japanese Patent Publication No. 56
It is disclosed in Japanese Patent No.-12568.

The curved type has a pair of front support columns set up at predetermined intervals corresponding to the size (width) of the load to be carried in in the running direction of the loading/unloading device, and the bottom sides of the load are placed at opposite positions of the left and right columns. A supporting arm rail is attached between the front and rear supports. A plurality of loading/unloading shells are moved in and out of the loading/unloading device according to the size of the load to carry in the load.

In addition, the latter is equipped with a shelf in which a pair of front and rear shelves are supported along the running direction of the loading/unloading device, and is supported by multiple sets of supports, and the loading/unloading device is equipped with a roller conveyor device for loading/unloading. It is something.

Problems to be Solved by the Invention In the former case, the spacing between the supports is set according to the size (width) of the load, and the storage amount of the load is determined for the type (size) of the load. When different amounts of cargo are received unevenly, a play space is created that cannot be carried by the person carrying it, and the storage capacity of the entire shelf may not be utilized effectively.

In addition, although the latter type is flexible with respect to the size of the load,
Since a roller conveyor device is used for loading, it cannot be used for items that are likely to be damaged by activities on the shelves or for loads that have a problem with the depth.Also, since a roller device is used, errors in the loading position on the shelves can be avoided. was likely to become large. moreover,
It is conceivable to use a pallet and use a fork or other loading/unloading tool, but there is a problem in that it is difficult to determine the insertion position of the loading/unloading tool. Furthermore, it is not possible to load or unload cargo from the front support column, and there is a lot of idle space in this area where cargo cannot be carried in, resulting in a low utilization efficiency of the storage surface of the shelf.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide warehouse equipment that can efficiently store cargo of different sizes regardless of the ratio of the amount of cargo received, and that can accurately carry in the amount of cargo.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a warehouse facility equipped with shelves and a loading/unloading device that can move freely along a fixed path along the front surface of the shelves, in which the shelves are installed vertically. with a shelf frame,
It has cantilever-shaped arms protruding forward from the shelf frame and arranged at regular pitches in the running direction of the loading/unloading device, and is configured to be able to support loads across at least three or more of these arms. and the loading/unloading device,
At least three or more insertion/removal tools are provided which can be moved up and down and moved in and out on the II side, and which can be inserted between the arms.

Effects With the above configuration, there is no support on the front side of the shelf that would be an obstacle to loading and unloading loads, so loads can be efficiently stored in order on the arms, and even if loads of different sizes are placed on one side and entered, they will not mix. Can be stored. In addition, since the load/unloader selected from three or more is moved up and down through the arms to move in and out to load/unload the load, it is possible to carry in an accurate and stable amount of load.

Example An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a shelf disposed before and after a passage 2, and in the passage 2, a loading/unloading device @4 that can freely run on a fixed path 3 along the front surface of the shelf 1 is disposed. Ru. The shelf 1 includes pillars 5 (an example of a shelf frame) with an H-shaped cross section that are erected at regular pitches P in the running direction of the loading and unloading equipment@4, and pillars 5 that protrude forward at predetermined intervals in the vertical direction from the pillars 5. It is configured to be able to support loads 7A and 7B across at least three or more arms 6.

Note that this support 5 may have a shape that continues in the running direction of the loading/unloading device 4. The loading/unloading device 4 is a floor rail 8
A traveling machine stand 9 guided by the traveling machine stand 9, a pair of posts 10 erected on this moving machine stand 9, a weighing table 11 that can be raised and lowered by being guided by these posts 10, and a weighing table 11 arranged on these four lowering tables 11. For example, three fork-type loading and unloading tools 12A to 12G are provided and can be freely moved in and out on the @1 side, and an upper frame 14 that is attached between the upper ends of both posts 10 and guided by the ceiling rail 13.
It is composed of a control box 15 provided on the side of the traveling machine base 9, a traveling drive device @16, and a culm descent drive device 17. The said putting in/out tools 12Δ to 12C are the arm pitch P of 111.
The pallets 7A, 7B(7)l@(actual 1!

18B width) and is selected and driven in and out.

In this warehouse facility, the cargoes 7A and 7B handled are, for example, two types of cargoes 7A and 7B having different widths.

7] The amount is carried in via pallets 18A and 18B corresponding to 3. As a standard for designing this shelf 1,
For example, a pallet 18A on which a smaller load 7A can be placed.
The width L1 is adopted. That is, in the stored state of the shelf 1, as shown in FIG. 4, the pallets 18A, 1
The pallet 8B is placed over at least three arms 6, and the arms 6 supported at both ends are set to support both ends of the pallets 18A and 183, which are carried in adjacently at the same time. . Therefore, the relationship between the width L1 of the pallet 18A and the pitch P of the arm 6 is 2P=11+2α1.

Here, α1 is a gap from the center of the arm 6 that allows insertion error of the pallet 7A, and the relationship between this gap α1 and the width W of the arm 6 is α1 < W/2. Further, this arm width W is set in relation to the width a of the loading/unloading tools 12A to 12C, and P=W+(a+2β).

Here, β is a gap that allows an error in the insertion position of the loading/unloading tools 12A to 12C, that is, an error in the stopping position of the loading/unloading device 4.

From the above conditions, each value can be set, and the width L2 of the pallet 183 on which the larger load 7B is placed is L1 +
P, and even if a palette with a wider width than this is used, the width will be Lx=Lt+xp (x is an integer).

Note that since there is an allowable range of the gap α depending on the arm width W, the width lx is allowed to be changed within a predetermined range.

In this embodiment, as an example, P=590, W=27

In addition, here, the width ρ1 of the loads 7A and 7B. ρ2 is g
It is desirable that 1≦L1 and J22≦L2.

The loading and unloading device 4 carries in the loads 7A and 7B using two and three loading/unloading tools 12A to 12C, respectively. As shown in Fig. 5(a), the smaller load 7A
To carry the cargo 17A into the cargo handling area 19, the two adjacent loading and unloading tools, for example 12A and 12B, are protruded to remove the receiver at a predetermined position, and after placing the load 17A on the lifting table 11, the loading and unloading device 4 is moved. While running, the lifting platform 11 is raised and lowered and stopped in front of the arm 6 of a predetermined AL. and,
Input/output shell 12A.

12B is projected above the center position between the arms 6 to be carried in (the center position of the pitch P), and then lowered downward through the arms 6, and the load 7A is placed on the arms 6. Then, the loading/unloading tools 12A and 12B are retracted to complete the loading. Carry out the procedure in reverse order as above.

In the case of the larger load 7B, as shown in FIG. 5(b), the above operation is performed by three loading/unloading shells 12A.

128 and 120 may be used.

According to the above embodiment, the pallets 18A, 18B (loads 7Δ, 7B) are supported between three or four arms 6, the side ends of the pallets 18A, 18B are supported on the arms 6, and Since both ends of the adjacent pallets 18A and 18B are supported on the cross arm 6 at this end, the loads 7A and 7B can be stably supported, and the play space between the adjacent pallets 18A and 18B is also reduced. It can be made extremely small.

Furthermore, since the load is always stored between a plurality of arm pitches 1, the location of the load can be easily memorized and detected.

Further, by moving the loading/unloading tools 12A to 12C in and out at the center position of the pitch P, the loads 7A and 7B can be stably supported on the loading/unloading tools 12A to 12C, and can be carried in.

In the above example, two types of Valen 1-18A were used.

18B (loads 7A, 7B) were stored, but three or more types may be stored, and in this case, a loading/unloading tool is provided for each pinch.Also, although pallets 18A and 18B were used, loads 7A and 7B It is also possible to import and unload directly.

Effects of the Invention As described above, according to the present invention, the @ front side support that is an obstacle to loading and unloading is eliminated, and the arms protruding forward are arranged in a cantilevered manner at predetermined pitches. Since the load is supported between the arms as described above, even if the amount of arrived loads of different widths is uneven, it can be efficiently stored in a mixed manner. In addition, since the load is carried in through the arms using three or more loading/unloading tools, loading and unloading can be carried out more accurately and more stably than when using a roller conveyor device.
