  The present invention relates to a three-dimensional automatic warehouse for storing and storing articles and a method for using the same.

  In general, a three-dimensional automatic warehouse for storing and storing articles includes a plurality of article storage units composed of a plurality of support columns and an article placement member supported by the support columns, and the articles are taken in and out of the article storage units. And a stacker crane. Then, the article is placed directly on the article placement member constituting the article storage section, or the pallet on which the article is placed is placed on the article placement member to store and store various articles. It has become.

  At that time, since the height of the articles to be stored is often almost constant, the vertical interval between the article mounting members is constant so that the height of each article storage section is constant. Thus, each article placement member is semi-permanently fixed to the column by welding, rivets or the like.

  However, in recent years, the height of articles to be stored has been increased due to diversification of articles and the like, and in the conventional structure in which each article mounting member is semi-permanently fixed to a column, the articles are stored. If you try to change the position of each article placement member in the vertical direction in response to the change in the height of the article, a large work is required, so if the height of the article to be stored is low, The waste of the height space of the article storage unit is used as it is, or the storage is abandoned when the height of the article to be stored becomes high.

  Therefore, recently, a three-dimensional automatic warehouse has been proposed in which the height of each article storage unit can be easily changed in accordance with the change in the height of the articles to be stored (for example, Patent Documents). 1-3.)

  In Patent Document 1, a plurality of attachment holes for attaching the article placement member to the support with bolts are provided along the height direction of the support, and an appropriate attachment hole is selected from among the attachment holes. A three-dimensional automatic warehouse is described in which the height of each article storage unit can be changed in accordance with a change in the height of the article to be stored by being attached to the column.

  Further, in Patent Document 2, a plurality of pallet receiving portions are provided in the height direction so as to face the opposite struts, and by selecting an appropriate pallet receiving portion from among them and placing the pallet, There is described a three-dimensional automatic warehouse in which the height of each article storage unit can be changed according to the change in height.

Further, in Patent Document 3, a plurality of front pallet receiving plates are provided in the height direction in the front pallet receiving plate on the column on which the stacker crane travels, and a plurality of rear pallet supports are provided in the height direction, respectively. Depending on the change in the height of the articles to be stored, the concave guide provided at the end of the pallet is placed on the front pallet receiving plate at an appropriate position, and the end of the rear pallet frame is placed on the rear pallet receiver at the corresponding position A three-dimensional automatic warehouse that can change the height of each article storage unit is described.

However, the three-dimensional automatic warehouse described in Patent Documents 1 to 3 described above has the following structural strength. There are problems.

  First, in the three-dimensional automatic warehouse described in Patent Document 1, since a large number of mounting holes are provided in the support column, a defect portion is generated in the support column cross section, and the performance as a structural member is deteriorated.

  In the three-dimensional automatic warehouse described in Patent Document 2, since the pallet is only placed on the pallet receiving portion, the pallet cannot play a role of supporting the horizontal force as a structural member and improving the buckling strength of the column. . Furthermore, there is a risk that the pallet may fall off the pallet receiving part in an earthquake or the like.

  Further, even in the three-dimensional automatic warehouse described in Patent Document 3, since the pallet frame is simply placed on the front pallet receiving plate and the rear pallet receiver, the role of supporting the horizontal force as the structural member and the role of improving the buckling strength of the support column. A pallet frame cannot bear. Furthermore, there is a risk that the pallet frame may fall off the front pallet receiving plate and the rear pallet receiving in an earthquake or the like.

A three-dimensional automatic warehouse characterized in that a receiving metal fitting having an insertion hole to be inserted and removed from above is provided.

  [2] The method of using the three-dimensional automatic warehouse according to [1], wherein when the support position of the article placement member is changed in the vertical direction of the column, the article placement member is held by the stacker crane and moved up and down And using the three-dimensional automatic warehouse characterized in that the support position is changed.

  In the present invention, the locking bracket provided to project downward at the end of the article mounting member is removably inserted into the insertion hole provided at a predetermined interval in the vertical direction of each column. Therefore, the height of each article storage section can be easily changed according to the height of the article to be stored, and the article placement member is firmly fixed to the column to support the horizontal force And the role of improving the buckling strength of the support can be maintained, and appropriate structural strength can be maintained.

  In addition, when changing the support position of the article placement member, the height is changed more easily because the stacker crane provided in the three-dimensional automatic warehouse is used. Is possible.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing the overall structure of a three-dimensional automatic warehouse according to one embodiment of the present invention. The three-dimensional automatic warehouse according to this embodiment has three rows in the horizontal direction as shown in FIG. And six columns 11 arranged in two rows in the depth direction (front-rear direction), an upper frame 16 connecting between the upper ends of the columns 11, and a lower frame 17 connecting the lower ends of the columns 11. The article placing member 21 supported by the column 11 is provided, and a plurality of article storage portions 20 are formed by them. In addition, although not shown in figure, the stacker crane for taking in / out articles | goods in those articles | goods storage parts 20 is provided.

  In order to support the article placing member 21 with the support column 11, a plurality of metal fittings 12 and metal fittings 13 are provided on the support column 11 at predetermined intervals, respectively, and receiving units provided at intervals of h in the vertical direction. By selecting either the metal fitting 12 or the receiving metal fitting 13 provided at an interval of H in the vertical direction and supporting the article placement member 21, the vertical distance of the article placement member 21 is changed, The height of each article storage unit 20 can be changed.

  That is, in FIG. 1A, the article placing member 21 is supported by the support metal fitting 12 in both the left row and the right row, and the heights of all the article storage portions 20 have the same dimension h. On the other hand, in FIG. 1B, in the left column, the height of the article storage unit 20 is h by supporting the article placing member 21 with the metal fitting 12, but in the left column, By supporting the article placement member 21 with the metal fitting 13, the height of the article storage unit 20 is H.

  Next, a support / connection structure between the support 11 and the article mounting member 21 for supporting the article mounting member 21 with the support 11 will be described with reference to FIGS.

  FIG. 2 is a perspective view showing a support / connection structure between the column 11 and the article placement member 21. As shown in FIG. 2, locking metal fittings 22 projecting downward are provided at both ends of the front pallet frame 21 a and the rear pallet frame 21 b that are the article placement members 21, and the vertical direction of each column 11. The receiving metal 12 having the insertion hole 12a into which the locking metal member 22 is removably inserted from above and the receiving metal 13 having the insertion hole 13a are provided at positions having a predetermined interval. The front pallet frame 21a is a pallet frame on the side on which the stacker crane runs, and the rear pallet frame 21b is a pallet frame on the side on which the stacker crane does not run. (Not shown) is arranged, and the stored article is placed on the pallet.

  And FIG. 3 is a figure which shows the state which the latching bracket 22 of the pallet frame 21a is inserted in the receiving bracket 12 provided in the support | pillar 11, and the support | pillar 11 and the pallet frame 21a are connected, (a). Is a front view, (b) is an AA arrow view in (a), (c) is an BB arrow view in (a). As shown in FIG. 3, the locking metal fittings 22 attached to both ends of the pallet frame 21 a with bolts 23 are inserted from above into the insertion holes 12 a of the receiving metal fittings 12 provided on the column 11, thereby The pallet frame 21a is firmly fixed and connected to the support column 11.

  On the other hand, FIG. 4 is a view showing a state in which the pallet frame 21 a is separated from the column 11. By moving the pallet frame 21 a upward, the locking bracket 22 of the pallet frame 21 a comes out of the insertion hole 12 a of the receiving bracket 12, and the pallet frame 21 a is separated from the column 11. As a result, the pallet frames 21a and 21b can be moved and installed at other support positions.

  When the support position is changed by moving the pallet frames 21a and 21b in the vertical direction, it is preferable to use a stacker crane provided in the three-dimensional automatic warehouse.

  That is, when the pallet frames 21a and 21b are placed on the arms of the stacker crane and lifted, and the locking bracket 22 is removed from the insertion hole 12a of the receiving bracket 12, the pallet frames 21a and 21b overlap with the receiving bracket 12 as viewed from above. Move horizontally until it disappears. Thereby, when the pallet frames 21a and 21b are moved up and down in order to change the support position, interference between the pallet frames 21a and 21b and the metal fittings 12 and 13 can be avoided. Next, the pallet frames 21a and 21b are moved to a height slightly above the metal fitting 13 to be connected. Then, after moving horizontally so that the locking metal fitting 22 is positioned above the insertion hole 13a of the metal fitting 13, the pallet frames 21a and 21b are lowered and the metal fitting 22 is inserted into the insertion hole 13a of the metal fitting 13. .

  As described above, in this embodiment, the locking metal fittings 22 provided so as to protrude downward at the end portions of the pallet frames 21a and 21b, which are article placement members, are provided with a predetermined interval in the vertical direction of each column 11. In this case, the height of each article storage unit 20 can be easily changed according to the height of the article to be stored. The pallet frames 21a and 21b are firmly fixed to the column 11, and can play a role as a structural member that supports the force in the horizontal direction and improve the buckling strength of the column 11, and maintain an appropriate structural strength. Is possible.

  Further, when changing the support positions of the pallet frames 21a and 21b, the stacker crane provided in the three-dimensional automatic warehouse is used for the change, so an external crane or the like is arranged and the change work is performed. This is unnecessary, and the height of each article storage unit can be changed more easily.

  In this embodiment, the front pallet frame 21a and the rear pallet frame 21b, which are article placement members, are independent. However, as shown in FIG. 5, the front pallet frame 21a and the rear pallet frame are used as the article placement members. 21b may be connected and integrated by a horizontal pallet frame 21c or a connected pallet frame 21d, and a pallet or a stored article may be placed on the integrated article placement member 25.

  And also when moving such an integrated article mounting member 25 in the up-down direction and changing the support position, it is preferable to use a stacker crane provided in this three-dimensional automatic warehouse.

  In this case, as shown in FIG. 6, the arm 41 of the stacker crane 40 is extended and inserted below the integrated article placement member 25. Then, the article placement member 25 is placed on the arm 41 of the stacker crane and lifted, and after the locking fitting 22 is removed from the insertion hole 12a of the receptacle 12, the article placement member 25 is overlapped with the receptacle 12 when viewed from above. The arm 41 of the stacker crane is contracted to a position where it becomes no longer, and the article placement member 25 is moved in the horizontal direction. Accordingly, when the article placement member 25 is moved up and down in order to change the support position, it is possible to avoid interference between the article placement member 25 and the metal fittings 12 and 13. Next, the article placement member 25 is moved to a height slightly above the metal fitting 13 to be connected. Then, after extending the arm 41 of the stacker crane and moving the article placement member 25 in the horizontal direction so that the locking fitting 22 is positioned above the insertion hole 13a of the receiving fitting 13, the article placement member 25 is lowered. Then, the locking fitting 22 is inserted into the insertion hole 13 a of the receiving fitting 13.

  In the above description, when the article placement member 25 is moved up and down, the front pallet frame 21a and the rear pallet frame 21b of the horizontal pallet frame 21c are prevented from interfering with each other. When the article placement member 25 is moved in the horizontal direction, the connection position of the pallet frames 21a and 21b is slightly moved in the horizontal direction. Since it is only necessary to prevent the metal fitting 12 from interfering, the horizontal movement distance can be shortened.

  In addition to the article placement member 25 described above, as shown in FIG. 7, the front pallet frame 21 a and the rear pallet frame 21 b are connected and integrated by a flat plate 23, and on the integrated article placement member 26. You may make it the structure which mounts a pallet and a storage article.

  And also when moving such an integrated article mounting member 26 to the up-and-down method and changing a support position, it is preferable to carry out using the stacker crane with which this solid automatic warehouse is equipped.

  The procedure at that time may be performed in the same manner as in the case of the article placing member 25 described above.

  Then, when the article placement member 26 is moved up and down in the vertical direction, the connecting portion of the flat plate 23 to the front pallet frame 21a and the rear pallet frame 21b is locked to prevent the flat plate 23 and the receiving brackets 12 and 13 from interfering with each other. If the article placement member 26 is moved in the horizontal direction, it is slightly moved in the horizontal direction so that the pallet frames 21a and 21b and the metal fitting 12 do not interfere with each other. Since it is only necessary to do so, the horizontal movement distance can be shortened.

  In the embodiment shown in FIGS. 2, 5, and 7, when it is desired to further increase the structural strength, the locking fitting 22 and the receiving fittings 12 and 13 may be bolted. In this case, a bolt hole is provided in the locking metal fitting 22, but it is not necessary to make a bolt hole in the support column 11, so that the structural strength of the support column 11 is not lowered as in the case of Patent Document 1.

  Further, in some cases, a locking plate 22 is provided only on the front pallet frame 21 a and inserted into the receiving bracket 12, and the locking plate 22 is not provided on the rear pallet frame 21 b, but a receiving plate provided instead of the receiving bracket 12. You may make it place an edge part on top.
