  Hereinafter, an automatic warehouse according to an embodiment of the present invention or a support structure for an upper rail for a stacker crane will be described with reference to the drawings as appropriate.

  FIG. 1 is a partial perspective view of an automatic warehouse 1 according to the embodiment, and FIG. 2 is a partial plan view of the automatic warehouse 1, and the automatic warehouse 1 faces in the front direction in FIG. A plurality of rack panels 2 as support panels arranged, a beam 4 extending from the upper part of each rack panel 2 to the left side, a reinforcing panel 6 passed between the lower part near the center of the beam 4, and a reinforcing panel 6 And an upper rail 8 fixed to the lower portion of the head.

  Further, the automatic warehouse 1 includes a stacker crane S as a moving body that is movable along the upper rail 8 by sandwiching the upper rail 8 between the rolling wheels T. The stacker crane S delivers or transports the load W to or from a rack (not shown) formed between the rack panels 2. Further, most of the stacker crane S is disposed on the left side of the upper rail 8 (opposite side of the rack panel 2).

  On the other hand, the reinforcing panel 6 has a lattice structure including left and right string members 11 and a lattice material 12. The upper rail 8 is fixed to the left string member 11.

  Further, as shown in FIG. 3, the left side of the reinforcing panel 6 is supported on the lower side of each beam 4 via the suspension bolt 13. The head 14 of the suspension bolt 13 is disposed on the upper side (inside the beam 4) of the long hole 16 in the left-right direction provided at the lower part of the beam 4. Further, the leg portion 18 of the suspension bolt 13 is fixed on a plate 20 provided on the left side of the reinforcing panel 6. The width of the long hole 16 is smaller than the diameter of the head 14 of the suspension bolt 13 and larger than the diameter of the leg 18 (about the diameter of the leg 18).

  Further, the right side of the reinforcing panel 6 is fixed to the rack panel 2 and is not fixed to the beam 4.

  In such an automatic warehouse 1, a support structure for the upper rail 8 is formed by each rack panel 2, each beam 4, the reinforcing panel 6 and the upper rail 8, and the following support can be performed by this support structure.

  That is, when the stacker crane S receives a load W in particular, a force in the left-right direction (mainly leftward) as shown by the arrow M in FIG. Then, the left side of the reinforcing panel 6 to which the upper rail 8 is attached first receives this force. Next, since the reinforcing panel 6 has a lattice structure, the received force is distributed to the string material 11 and the lattice material 12 as indicated by an arrow N. Further, since the right side of the reinforcing panel 6 (the side opposite to the upper rail 8) is fixed to the rack panel 2, the dispersed force can be transmitted to many rack panels 2. Therefore, in the automatic warehouse 1, even a local force such as the arrow M can be resisted by the large number of rack panels 2.

  Further, since the left side of the reinforcing panel 6 is supported by the beam 4 by the suspension bolts 13 that enter the elongated holes 16 in the left-right direction, the reinforcing panel 6 is moved in the left-right direction by a force as indicated by an arrow M generated by the stacker crane S. The suspension bolt 13 only moves in the long hole 16 even if the suspension bolt 13 moves. Therefore, in the automatic warehouse 1, the force as indicated by the arrow M is not transmitted to the beam 4, but is applied to the reinforcing panel 6. This prevents the force from being directly transmitted from the beam 4 to the single rack panel 2. In addition, the force as indicated by the arrow N in the reinforcing panel 6 is sufficiently dispersed.

  In addition, the reinforcing panel 6 is not dropped from the beam 4 by each suspension bolt 13 but is fixed in the vertical direction. Further, since the stacker crane S is movable along the upper rail 8 facing the front and back direction in FIG. 1 (vertical direction in FIG. 2), the suspension bolt 13 or the beam 4 and the reinforcing panel 6 in the direction of the direction. The force becomes minute and does not become a problem.

  In the support structure of the automatic warehouse 1 or the upper rail 8 as described above, the upper rail 8 for the stacker crane S, the plurality of rack panels 2 arranged in the direction of the upper rail 8, and the upper portion of each rack panel 2 are provided. A fixed beam 4 and a reinforcing panel 6 passed under each beam 4 are provided, and the upper rail 8 is fixed to the edge of the reinforcing panel 6 opposite to the rack panel 2. The edge of the reinforcing panel 6 on the upper rail 8 side is supported so as to be movable in the direction of the beam 4, and the edge of the reinforcing panel 6 on the rack panel 2 side is fixed to the rack panel 2. Therefore, the force generated by the stacker crane S can be distributed and transmitted to a large number of rack panels 2, and each rack panel 2 has only to resist a relatively small dispersion force, so that it is simple. Therefore, the cost can be reduced, the size can be reduced, or the load capacity can be increased.

  Further, since the reinforcing panel 6 has a lattice structure, the force can be efficiently dispersed with a simple configuration. Further, since the edge of the reinforcing panel 6 on the upper rail 8 side is supported by the suspension bolts 13 that enter the long holes 16 facing the direction of the beam 4, the reinforcing panel 6 is supported by the beam without transmitting force. The structure can be provided simply. In addition, since the beam 4 extends only to one side of the rack panel 2, the cantilever (one side support) upper rail as in the small-scale one-side rack type automatic warehouse 1 that has not been realized due to insufficient strength in the past. Support can be provided, and an automatic warehouse or the like can be installed in a space that could not be installed conventionally.

  In addition, the form of this invention formed mainly by changing the said form is illustrated.

  A component having a shape symmetrical to the above form is further provided, and an automatic warehouse having racks on both sides is provided. Alternatively, a beam is provided on both sides of the rack panel and a reinforcing panel and an upper rail are attached. Also in these cases, the rack panel can be made relatively simple, and an automatic warehouse capable of storing many loads at low cost and space-saving can be provided.

  Further, the rack panel and the reinforcing panel are assumed to be a lattice structure in which lattice materials are combined in an X shape, a lattice structure including orthogonal members, a plate-like body, or a combination thereof. Or it replaces with a long hole and a suspension bolt, and a beam and a reinforcement panel are joined by a bearing. The upper rail is fixed to the side surface of the reinforcing panel.

  The present invention can also be applied to other types of automatic warehouses including those provided with guide rails, devices related to other moving bodies, or upper rail support structures thereof.

It is a partial perspective view of the automatic warehouse which concerns on this invention. It is a partial top view of the automatic warehouse which concerns on this invention. FIG. 2 is an enlarged view around a suspension bolt in FIG. 1.
