It arrange | positions back and forth and regulates the movement of the said accommodation 100 in the entrance / exit direction (Y direction).

  The side stopper 13 is a cylindrical rod member that is long in the entry / exit direction (Y direction) of the stored item 100 and is welded to each base portion 11 (the back side base portion 11a, the intermediate base portion 11b, and the near side base portion 11c). Has been. The side stopper 13 is continuously provided so as to span both of the two storage spaces 2 a arranged in the entry / exit direction (Y direction) of the stored item 100. That is, the side stopper 13 is continuously provided so as to span all of the plurality of storage spaces 2a arranged in the entry / exit direction (Y direction). As shown in FIG. 2 (a), such a side stopper 13 is disposed on the side of the storage object 100 placed on the first stay 2c and the second stay 2d, and the entrance / exit direction of the storage object 100 is provided. The movement in the horizontal direction (X direction) orthogonal to the (Y direction) is restricted.

  As shown in FIG. 3, the locking portion 14 is connected to the left end of each base portion 11 (the back side base portion 11 a, the intermediate base portion 11 b, and the near side base portion 11 c), and extends downward from the base portion 11. It is provided towards. The locking portion 14 is disposed along (in contact with) the left side surface of the second stay 2d when the base portion 11 is installed at a predetermined location of the second stay 2d, and the lower end portion 14a is Locked to the lower surface of the second stay 2d.

  The first projecting portion 15 is a plate-like member formed by bending a part of each base portion 11 downward, and is arranged so as to sandwich the second stay 2d with the locking portion 14. . In addition, before the right side fall prevention member 10 is attached to the 2nd stay 2d, the 1st protrusion part 15 is made into the attitude | position inclined in the opposite side to the attitude | position shown in FIG.3 (b). Accordingly, it is possible to prevent the first protrusion 15 from interfering with the second stay 2d when the right fall prevention member 10 is attached to the second stay 2d. Then, after the base portion 11 is arranged at a predetermined position on the second stay 2d, the first projecting portion 15 is deformed into the posture shown in FIG. Is done. As a result, the locking portion 14 (including the lower end portion 14a) and the first protrusion 15 surround the second stay 2d without any gap, and the right fall prevention member 10 (fall prevention member 2f) moves in the X and Z directions. It can be prevented from moving.

  As shown in FIG. 3B, the second protrusion 16 is a plate-like member formed by bending the right end of the back base portion 11a downward. The second projecting portion 16 is installed at a position where the front end is in contact with the side surface of the first stay 2c arranged on the back side of the two first stays 2c arranged in the Y direction from the back side. ing. The third protrusion 17 is a member attached to the side stopper 13 by welding or the like so as to hang down below the side stopper 13. The third projecting portion 17 is installed at a position that comes into contact with the side surface of the first stay 2c arranged on the front side of the two first stays 2c arranged in the Y direction from the front side.

  For example, when the right fall prevention member 10 is about to move in the + Y direction, the movement of the right fall prevention member 10 can be prevented by the third protrusion 17 being caught by the first stay 2c. Further, when the right fall prevention member 10 is about to move in the −Y direction, the movement of the right fall prevention member 10 can be prevented by the second protrusion 16 being caught by the first stay 2c. Therefore, the second protrusion 16 and the third protrusion 17 can prevent the right-side fall prevention member 10 from moving in the Y direction.

  In addition, the shape and arrangement | positioning of the 2nd projection part 16 and the 3rd projection part 17 are not restricted to the example of this embodiment. For example, the second protrusion 16 may be disposed so as to contact the first stay 2c from the front side, and the third protrusion 17 may be disposed so as to contact the first stay 2c from the back side. Moreover, you may arrange | position the 2nd projection part 16 and the 3rd projection part 17 so that it may contact | abut to the same 1st stay 2c. The third protrusion 17 may be formed by bending a part of the side stopper 13. Furthermore, only one of the second protrusions 16 and the third protrusions 17 may be provided.

  Returning to FIG. 2, the SUS band 2g ties the fall prevention member 2f to the first stay 2c by binding the side stopper 13 of the fall prevention member 2f and the stopper 2e provided on the first stay 2c. It is to be fixed. As shown in FIG. 2A, two SUS bands 2g are provided for one stopper 2e. In addition, since the weight of the container 100 is relatively small, the SUS band 2g is not installed when a large force is difficult to act on the fall prevention member 2f even if the container 100 is suddenly moved due to an earthquake or the like. The movement of the fall prevention member 2f may be prevented only by the second projecting portion 16 and the third projecting portion 17. In addition, the movement of the fall prevention member 2f can be prevented only by the SUS band 2g without providing the second protrusion 16 and the third protrusion 17. However, by using the 2nd projection part 16 and the 3rd projection part 17, and SUS band 2g together, it can prevent completely that the fall prevention member 2f moves from the rack 2. FIG.

  In such a rack 2 of this embodiment, when the container 100 tries to move in the left-right direction (X direction) due to vibration such as an earthquake, the movement is regulated by the side stopper 13. Further, when the object 100 tries to move in the entry / exit direction (Y direction), the movement is restricted by the front / rear stopper 12.

  In the rack 2 of the present embodiment as described above, the two storage spaces 2a in which the fall prevention members 2f (the right fall prevention member 10 and the left fall prevention member 20) are arranged in the entry / exit direction (Y direction) of the stored item 100. The side stopper 13 is provided continuously so as to hang over both. For this reason, in a state before the fall prevention member 2f is retrofitted to the rack 2, there is no stopper that prevents the left and right movement of the contents 100 (that is, two accommodation spaces in the entry / exit direction). 2a), the lateral stopper 13 can be disposed, and the effect of preventing the stored item 100 from moving in the left-right direction is also obtained at such a location.

  That is, in the rack 2 of the present embodiment, the side stopper 13 is provided so as to face the entire side surface of the stored item 100 stored in the storage space 2a when viewed from above. For this reason, even when the container 100 is about to rotate due to vibration such as an earthquake, the rotation can be restricted by the side stopper 13. Therefore, according to the rack 2 of the present embodiment, although the storage space 2a is a double rack in which two storage spaces 2a are arranged in the entry / exit direction (Y direction) of the storage object 100, the storage object 100 is provided by the fall prevention member 2f. The movement of the container 100 can be prevented and the fall of the stored item 100 from the first stay 2c and the second stay 2d can be prevented. As a result, the stored item 100 is prevented from falling on the track of the stacker crane 3, and the recovery work after an earthquake or the like is facilitated.

  Further, since the SUS band 2g is bound so as to surround the side stopper 13, for example, when the container 100 is lifted from the rack, the end of the container 100 should come into contact with the side stopper 13. Even in the case where there is a problem that the fall prevention member 2f is lifted upward, the effect of preventing the occurrence is also achieved. Regarding this effect, it can be said that the effect of the SUS band 2g is superior to the second protrusion 16 and the third protrusion 17.

  Moreover, in this embodiment, in the right side fall prevention member 10 and the left side fall prevention member 20, the base part 11, the front-and-rear stopper 12, the side stopper 13, the locking part 14, and the first protrusion part 15 are provided. The second protrusion 16 and the third protrusion 17 are integrated. For this reason, the attachment work of fall prevention member 2f can be performed easily.

  Further, in the present embodiment, the fall prevention member 2f is disposed along the second stay 2d, and the lower end portion 14a is locked to the lower surface of the second stay 2d and is connected to the base portion 11. The second stay 2 d is sandwiched between the portion 14 and the locking portion 14, and the first protrusion 15 is provided connected to the base portion 11. For this reason, it can prevent that the fall prevention member 2f moves on the 2nd stay 2d by the latching | locking part 14 and the 1st projection part 15, and it can prevent that the fall prevention member 2f falls from the 2nd stay 2d. it can.

  Further, the front and rear stoppers 12 are not provided on the right side fall prevention member 10A and the left side fall prevention member 20A. When the front and rear stoppers 12 are present, for example, when the size of the stored item 100 is large, the front and rear stoppers 12 are hung on the installation area of the stored item 100 when the fall prevention member 2fA is to be installed later. As a result, it may happen that the installation of the fall prevention member 2fA has to be abandoned. On the other hand, when the front-rear stopper 12 does not exist in the right-side fall prevention member 10A and the left-side fall prevention member 20A, such a problem can be avoided, and the rack 2 that accommodates a large-sized accommodation item 100. On the other hand, the fall prevention member 2fA can be attached later.

  Further, when the front / rear stopper 12 is present on the right-side fall prevention member 10 </ b> A and the left-side fall prevention member 20 </ b> A, the front / rear stopper 12 can be an obstacle to taking in / out the stored item 100. On the other hand, when the front / rear stopper 12 is removed from the right side fall prevention member 10A and the left side fall prevention member 20A as in the present embodiment, the front / rear stopper 12 is avoided when the object 100 is put in and out. There is no need to perform an operation, and the contents 100 can be taken in and out smoothly.

  In this way, even when the front and rear stoppers 12 are not present on the right side fall prevention member 10A and the left side fall prevention member 20A, the fall prevention member 2fA of the present embodiment has a cylindrical protrusion as described later. Since the horizontal movement of the container 100 is prevented by the portion 18, 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 18 is provided. For this reason, compared with the case where the fall prevention member 2fA is not provided with the cylindrical protrusion 18, 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 18 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.

  Further, the fall prevention member 2fA of the present embodiment includes a plurality of cylindrical protrusions 18. For this reason, even if it is a case where the mounting position of the stored item 100 is slightly shifted due to a transport error by the stacker crane 3, the stored item 100 can be reliably mounted on the cylindrical protrusion 18. 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 18. Even so, the possibility that any one of the cylindrical protrusions 18 directly contacts the pallet increases, 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 protrusion 18 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 18 at such a place where bending is most difficult, the container 100 and the cylindrical protrusion 18 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.

  Further, in the fall prevention member 2fA of the present embodiment, the cylindrical protrusions 18 are arranged in a straight line. Accordingly, 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 18 can be reliably brought into contact with each other. 100 horizontal movements can be prevented. For example, when the cylindrical protrusions 18 are two-dimensionally arranged, the cylindrical protrusions 18 can be arranged in a wider range, and the probability that the container 100 abuts any of the cylindrical protrusions 18. Can be increased. On the other hand, when the lower surface of the container 100 is not a perfect plane due to bending of the pallet or the like, it is difficult to predict which cylindrical protrusion 18 will contact. For this reason, for example, in the right fall prevention member 10A and the left fall prevention member 20A, the number of cylindrical protrusions 18 in contact with the accommodation 100 varies, and the regulation force for the horizontal movement of the accommodation 100 depends on the direction. It can be different. 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 18 are arranged in a straight line, all the cylindrical protrusions 18 are placed in the container 100 more than in the case of two-dimensional arrangement, although it depends on the bending direction and the amount of bending. The possibility of contact is increased.

  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 18 is provided for one fall prevention member 2fA has been described. However, the present invention is not limited to this, and for example, it is possible to adopt a configuration in which a plurality of cylindrical protrusions 18 are provided. Thereby, the cylindrical protrusion 18 can be arranged in a wide range, and the probability that the stored item 100 comes into contact with any of the cylindrical protrusions 18 can be increased. Moreover, you may make it provide the single cylindrical protrusion part 18 with respect to one fall prevention member 2fA.

  Further, for example, the cylindrical protrusions 18 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 18 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 18 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 18. As a result, the contact area between the cylindrical protrusion 18 and the container 100 can be further reduced, and the surface pressure between the cylindrical protrusion 18 and the container 100 can be further increased.
