For this reason, when the storage object 100 is stored in the storage space 2a, these cylindrical protrusions 16 support the storage object 100 from below. Such a cylindrical protrusion 16 is formed by, for example, pressing. All the cylindrical protrusions 16 have the same height and are set so as not to exceed the height of the stopper 12.

  As described above, when the storage object 100 is stored in the storage space 2a, the storage object 100 is supported by these cylindrical protrusions 16, and therefore, compared with the case where the cylindrical protrusion 16 is not installed. Thus, the contact area between the right back fall prevention member 10A and the accommodation 100 is reduced, and the surface pressure between the right back fall prevention member 10A and the accommodation 100 can be increased. That is, these cylindrical protrusions 16 increase the surface pressure between the right rear fall prevention member 10 </ b> A and the stored item 100.

  As shown in FIG. 4A, the second projecting portion 17 has a part of the base portion 11 with a fold line L1 that is long in the horizontal direction (X direction) perpendicular to the entering / exiting direction (Y direction) of the container 100 as a fold. It is formed by bending downward. This 2nd projection part 17 consists of a rectangular-shaped board part by which the front and back were orient | assigned to the entrance / exit direction (Y direction) of the stored article 100. FIG.

  The second projecting portion 17 is arranged at a position where the surface abuts the first stay 2c when the base portion 11 is installed at a predetermined location of the first stay 2c and the second stay 2d. Yes. By being arranged at such a position, the second projecting portion 17 sandwiches the first stay 2c between the first locking portion 13 and the second projecting portion 17 as shown in FIG. 4A, for example.

  As shown in FIG. 5A, the left back fall prevention member 20A has a shape that is symmetrical to the right back fall prevention member 10A. Further, as shown in FIG. 5 (b), the right front drop prevention member 30A has a shape symmetrical with the right back fall prevention member 10A described above and excludes portions corresponding to the back stopper 12a and the right stopper 12b. Has a shape. Further, the left front drop prevention member 40A has a shape symmetrical to the right back fall prevention member 10A described above and to the left and right and front and back, and has a shape from which portions corresponding to the back stopper 12a and the right stopper 12b are removed. Yes.

  When the right front drop prevention member 30A and the left front drop prevention member 40A have a portion corresponding to the back side stopper 12a of the right back fall prevention member 10A, the corresponding portions are the right front drop prevention member 30A and the left front drop prevention, respectively. The member 40A is disposed on the front end, that is, on the stacker crane 3 side. For this reason, for example, when the size of the container 100 is large, if the fall prevention member 2fA is to be installed later, the rear side stopper 12a of the right front fall prevention member 30A and the left front fall prevention member 40A are arranged. Corresponding parts may be placed on the installation area of the container 100, and as a result, it may happen that the installation of the fall prevention member 2fA has to be abandoned. On the other hand, such a problem is avoided when the right front fall prevention member 30A and the left front fall prevention member 40A do not have a portion corresponding to the back side stopper 12a of the right back fall prevention member 10A. The fall prevention member 2fA can be attached later to the rack 2 that accommodates the large-sized accommodation 100.

  Further, when the right front fall prevention member 30A and the left front fall prevention member 40A have a portion corresponding to the back stopper 12a of the right back fall prevention member 10A, the portion serves as an obstacle to taking in and out the contents 100. obtain. On the other hand, as in the present embodiment, when the portion corresponding to the back side stopper 12a of the right back fall prevention member 10A is removed from the right front fall prevention member 30A and the left front fall prevention member 40A. In addition, it is not necessary to perform an operation of avoiding the part when the container 100 is taken in and out, and the container 100 can be smoothly taken in and out.

  In this way, even if the right front drop prevention member 30A and the left front drop prevention member 40A do not have a portion corresponding to the back stopper 12a of the right back fall prevention member 10A, the fall of the present embodiment According to the prevention member 2fA, since the horizontal movement of the container 100 is prevented by the cylindrical protrusion 16 as described later, the container 100 can be prevented from falling due to an earthquake or the like.

  The fall prevention member 2fA of the present embodiment having such a configuration protrudes upward from the upper surface of the base portion 11 in the placement area of the accommodation object 100, and supports the accommodation object 100 placed in the placement area from below. A cylindrical protrusion 16 is provided. For this reason, compared with the case where the fall prevention member 2fA is not provided with the cylindrical protrusion 16, the surface pressure between the fall prevention member 2fA and the contained item 100 is increased, and the contained item 100 is prevented from moving due to an external force. Can do. In particular, when the container 100 has a pallet made of resin or wood, the tip of the cylindrical protrusion 16 slightly bites into the pallet due to an increase in surface pressure, and the movement of the container 100 is more reliably prevented. It becomes possible to do. In addition, when such a cylindrical protrusion 16 is installed, since the horizontal movement of the object 100 can be prevented by the cylindrical protrusion 16, all the stoppers 12 can be omitted.

  Further, the fall prevention member 2fA of the present embodiment includes a plurality of cylindrical protrusions 16. For this reason, even if it is a case where the mounting position of the storage thing 100 shifts | deviates slightly by the conveyance error by the stacker crane 3, the storage object 100 can be reliably mounted on the cylindrical protrusion part 16. FIG. For example, some of the pallets included in the container 100 have a complicated shape such as a lattice on the back surface, but the back surface of the pallet has a complicated shape by providing a plurality of cylindrical protrusions 16. Even so, the possibility that any one of the cylindrical protrusions 16 directly contacts the pallet is increased, and the horizontal movement of the contents 100 can be reliably prevented.

  Further, in the fall prevention member 2fA of the present embodiment, the cylindrical protruding portion 16 is provided at a location overlapping the second stay 2d in plan view. Since the second stay 2d is stronger than the fall prevention member 2fA, the second stay 2d (or the first stay) of the fall prevention member 2fA when the stored item 100 is placed on the fall prevention member 2fA. The portion overlapping the stay 2c) is most difficult to bend. By providing the cylindrical protrusion 16 at such a position where bending is most difficult, the container 100 and the cylindrical protrusion 16 can be reliably brought into contact with each other, and the horizontal movement of the container 100 can be more reliably prevented. It becomes possible.

  Moreover, in the fall prevention member 2fA of this embodiment, the cylindrical protrusions 16 are arranged in a straight line. Thereby, even if the lower surface of the container 100 is not a perfect plane due to the deformation of the container 100, the container 100 and the cylindrical protrusion 16 can be reliably brought into contact with each other. 100 horizontal movements can be prevented. For example, when the cylindrical protrusions 16 are two-dimensionally arranged, the cylindrical protrusions 16 can be arranged in a wider range, and the probability that the container 100 abuts any one of the cylindrical protrusions 16. Can be increased. On the other hand, when the lower surface of the container 100 is not a perfect plane due to the bending of the pallet or the like, it is difficult to predict which cylindrical protrusion 16 abuts. For this reason, for example, in the right rear fall prevention member 10A, the left rear fall prevention member 20A, the right front fall prevention member 30A, and the left front fall prevention member 40A, the number of the cylindrical protrusions 16 that are in contact with the contents 100 is increased. It is also conceivable that variations occur and the regulation force for the horizontal movement of the container 100 varies depending on the direction. As a result, the regulation force in the specific direction becomes unexpectedly weak, and there is a possibility that the container 100 may be allowed to move when the container 100 moves horizontally in that direction. On the other hand, when the cylindrical protrusions 16 are arranged in a straight line, all the cylindrical protrusions 16 are placed in the storage object 100 as compared to the case of two-dimensional arrangement, although depending on the bending direction and the amount of bending. The possibility of contact is increased. Actually, when the cylindrical protrusions 16 are arranged at the vertices of a quadrangle and arranged two-dimensionally, it has been confirmed that some cylindrical protrusions 16 and the object 100 are not in contact with each other. When three cylindrical protrusions 16 were arranged in a straight line, all the cylindrical protrusions 16 were in contact with the contents 100.

  As described above, the preferred second embodiment of the present invention has been described with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiment. Various shapes, combinations, and the like of the constituent members shown in the above-described embodiments are examples, and various modifications can be made based on design requirements and the like without departing from the spirit of the present invention.

  For example, in the above embodiment, the configuration in which only one row of the cylindrical protrusions 16 is provided for one fall prevention member 2fA has been described. However, the present invention is not limited to this. For example, it is possible to adopt a configuration in which a plurality of cylindrical protrusions 16 are provided. Thereby, the cylindrical protrusion 16 can be arranged in a wide range, and the probability that the stored item 100 abuts on any of the cylindrical protrusions 16 can be increased. Moreover, you may make it provide the single cylindrical protrusion part 16 with respect to one fall prevention member 2fA.

  Further, for example, the cylindrical protrusions 16 may be arranged so as to be the vertices of a triangle. In such a case, the stored object 100 can be stably supported when all the cylindrical protrusions 16 are in contact with the stored object 100.

  Moreover, in the said embodiment, the structure which the protrusion part of this invention is the cylindrical protrusion part 16 was demonstrated so that it could produce easily by press work. However, the present invention is not limited to this. For example, a bottomed cylindrical protrusion whose upper end is closed may be used as the protrusion of the present invention. In such a case, for example, by making the upper end surface of the bottomed cylindrical projecting portion rough, the frictional force acting between the projecting portion and the stored object 100 is increased, and the stored object 100 You may increase the control power with respect to a horizontal movement more. Further, a configuration in which the protruding portion is formed separately and attached to the base portion 11 may be adopted. In such a case, the shape of the protruding portion can be freely set, and for example, the shape of the protruding portion can be changed according to the contents 100.

  Further, for example, a plurality of notches may be provided on the upper end of the cylindrical protrusion 16. As a result, the contact area between the cylindrical protrusion 16 and the container 100 can be further reduced, and the surface pressure between the cylindrical protrusion 16 and the container 100 can be further increased.
