Description

  The present invention relates to a shelf facility used in an automatic warehouse or the like.

  A shelf facility used in an automatic warehouse or the like usually includes a plurality of storage shelves in which a plurality of luggage storage units are arranged in the vertical and horizontal directions. In general, an article to be stored and a pallet on which the article is placed are stored as luggage in the luggage storage unit.

  In this type of shelf equipment, a stopper may be provided to the luggage storage section in order to prevent the luggage from jumping out from the inside of the luggage storage section. However, even when such a stopper is provided, if a plurality of stacked items are stored as luggage in the luggage storage unit, when the pallet and the stopper collide, the items on the pallet continue to move due to inertia. In some cases, the cargo collapses.

  As a countermeasure, Patent Document 1 discloses a shelf facility in which a load receiving member on which a load is placed has a hollow structure, a viscoelastic body is disposed inside the load receiving member, and the viscoelastic body is incorporated in a stopper. . In this shelf facility, when the load collides with the stopper, the impact is reduced by the deformation of the viscoelastic body of the stopper to prevent the collapse of the load.

  As another proposal, Patent Document 2 discloses a shelf facility in which a stopper is made of an elastic material. Even in this shelf facility, when the load collides with the stopper, the shock is mitigated by the deformation of the stopper to prevent the collapse of the load.

  The connecting material 32 is constructed between the pair of support columns 28 and 30 along the front-rear direction X. The connecting material 32 is constructed so as to straddle the respective supports 28 and 30 of the pair of storage shelves 18.

  The lattice 34 is disposed obliquely with respect to the horizontal plane, and is laid between the front column 28 and the rear column 30. The plurality of lattices 34 are arranged so as to be bent in a zigzag shape in the front-rear direction. The plurality of lattices 34 are connected to the front column 28 and the rear column 30 using bolts and nuts (not shown).

  As shown in FIGS. 4 to 6, the luggage entrance 21 of the luggage storage unit 20 is formed between a pair of front struts 28 adjacent in the left-right direction Y.

  The placement surface 36 of the cargo receiving member 38 is provided so as to be located on the back side (the right side in FIG. 6) with respect to the luggage entrance 21. The load receiving member 38 of the present embodiment is configured by a pair of load receiving members 38 that are individually attached to each of two sets of struts 28 and 30 adjacent in the left-right direction Y. The load receiving member 38 includes a pair of arm members 42 that are individually connected to a pair of support columns 28 and 30 that are adjacent to each other in the front-rear direction X, and an erection member 44 that is laid between the pair of arm members 42.

  The arm member 42 is a long material extending along the left-right direction Y from the connection position to the support columns 28 and 30. The pair of arm members 42 are arranged in parallel to each other. The arm member 42 of the present embodiment extends from the connection position to the support columns 28 and 30 to both sides in the left-right direction Y, and each of the both side portions constitutes a load receiving member 38 of the load storage unit 20 adjacent in the left-right direction Y. ing.

  The erection member 44 is connected to the ends in the left-right direction Y of each of the pair of arm members 42. The erection member 44 is fixed to the columns 28 and 30 via a pair of arm members 42 and is cantilevered by the pair of arm members 42. The erection member 44 is a long material extending along the front-rear direction X from the connection position with respect to each of the pair of arm members 42. The erection member 44 has a protrusion 44 a that protrudes forward from the front arm member 42 of the pair of arm members 42. The protruding portion 44a of the erection member 44 and the front support column 28 are arranged with a space in the left-right direction Y, and a gap 46 is formed between them.

  The loading surface 36 of the load receiving member 38 is formed on the upper surface of the load receiving member 38, more specifically on the upper surface of the erection member 44 and the upper surface of the arm member 42. The load W is placed on the placement surface 36 of each of the pair of load receiving members 38.

FIG. 7 is an enlarged view of the stopper 40 of FIG.
As shown in FIGS. 5 and 7, the stopper 40 is provided at the front end 38 a of the cargo receiving member 38. The stopper 40 is disposed in a gap 46 formed at the front end portion 38 a of the cargo receiving member 38 and between the projecting portion 44 a of the erection member 44 and the front column 28. More specifically, the stopper 40 is disposed at a position near the erection member 44 in the gap 46.

  The stopper 40 of the present embodiment is configured by a member different from the cargo receiving member 38. The stopper 40 is made of a hard material such as metal or resin. The stopper 40 of this embodiment is attached to the arm member 42 of the cargo receiving member 38 via the attachment member 48.

  The attachment member 48 is made of a hard material such as metal or resin. The attachment member 48 includes a fixed portion 48 a provided on the rear side of the attachment member 48 and a stopper fixing portion 48 b provided on the front side of the attachment member 48. The fixed portion 48a is fixed to the front side surface of the arm member 42 by using a fixture 50 in which a bolt and a nut are combined. The stopper fixing portion 48 b has a first portion 48 c disposed on the lower side with respect to the stopper 40 and a second portion 48 d disposed on the front side with respect to the stopper 40. The stopper 40 is fixed to the stopper fixing portion 48b by adhesion or the like after abutting against the upper surface of the first portion 48c or the rear surface of the second portion 48d of the stopper fixing portion 48b.

  As shown in FIG. 7, the stopper 40 is provided so as to protrude above the placement surface 36 of the load receiving member 38. In the stopper 40, an inclined surface 52 is formed on the upper surface of the stopper 40. The inclined surface 52 gradually increases in height from the placement surface 36 of the load receiving member 38 toward the front side. The height here refers to a distance in the vertical direction Z (vertical direction) from the floor surface 26 (see FIG. 1).

  The rear surface 52 a of the inclined surface 52 is disposed below the placement surface 36 of the load receiving member 38. The inclined surface 52 has a front end 52b above the placement surface 36 and below the article Wa of the luggage W (see also FIG. 6). The inclined surface 52 is formed so as to be at the same height as the mounting surface 36 at a midway position from the rear side to the front side. The inclined surface 52 is formed to smoothly continue from the rear end 52a toward the front end 52b. The inclined surface 52 of the present embodiment is formed flat so as to extend linearly from the rear end 52a toward the front end 52b.

  The operation of the above shelf facility 10 will be described. FIG. 8 is a schematic diagram for explaining the operation of the shelf facility 10. FIG. 8A shows the load W on the placement surface 36 of the load receiving member 38 when the shelf facility 10 is in a stationary state where it does not vibrate. Here, a case where a plurality of stacked articles Wa and pallets Wb constitute one unit of luggage W will be described as an example.

  When horizontal vibration due to an earthquake is transmitted from the floor 26 to the storage shelf 18, the storage shelf 18 vibrates in the front-rear direction X and the left-right direction Y. When the storage shelf 18 vibrates in the front-rear direction X, the vibration is also transmitted to the load W on the load receiving member 38, and the load W is relatively displaced in the front-rear direction X with respect to the load receiving member 38. As shown in FIG. 8B, when the load W on the load receiving member 38 is relatively displaced forward (see direction Pa) with respect to the load receiving member 38, the pallet Wb of the load W contacts the stopper 40.

  Here, an inclined surface 52 is formed on the stopper 40. For this reason, as shown in FIG. 8C, the pallet Wb in contact with the inclined surface 52 of the stopper 40 together with the article Wa on the pallet Wb is displaced relative to the load receiving member 38 to the front side while being displaced relative to the load receiving member 38. It can be raised along (see direction Pb). Thereby, the kinetic energy of the load W having the pallet Wb and the article Wa can be converted into potential energy, and the relative speed of the load W with respect to the load receiving member 38 in the front-rear direction X can be gradually reduced.

  After the relative speed of the load W with respect to the load receiving member 38 in the front-rear direction X becomes zero, a load that causes the load W on the load receiving member 38 to be displaced rearward relative to the load receiving member 38 is transmitted to the load W. Consider the case. In this case, since a part of the pallet Wb of the load W is placed on the inclined surface 52, as shown in FIG. 8D, the pallet Wb together with the article Wa on the pallet Wb is placed on the load receiving member 38 by its own weight. On the other hand, it becomes easy to relatively displace to the rear side, and it becomes easy to return the load W to the rear side (see direction Pc) by its own weight.

The effect of the above shelf equipment 10 is demonstrated.
Since the inclined surface 52 is formed in the stopper 40, as described above, when the load W that is displaced relative to the load receiving member 38 comes into contact with the stopper 40, it is possible to prevent a rapid change in speed. For this reason, the impact of the load W caused by the collision with the stopper 40 can be reduced, and the collapse of the load of the article Wa on the pallet Wb can be prevented.

  Moreover, in the shelf installation 10 of embodiment, the above-mentioned load collapse prevention effect can be acquired by using the simple structure like the stopper 40 in which the inclined surface 52 was formed in the upper surface. Therefore, there is an advantage that labor and cost required for assembling the stopper 40 to the cargo receiving member 38 can be suppressed.

  Moreover, in the shelf equipment 10 of embodiment, the stopper 40 is comprised with the hard material instead of the elastic body. Therefore, unlike the shelf equipment of patent document 2, the elastic body which comprises the stopper 40 does not remain in the state which was crushed, and the load collapse prevention effect can be acquired stably.

  In addition, according to the shelf equipment 10 of the embodiment, as in Patent Document 1, the load receiving member does not have to have a hollow structure in order to arrange the viscoelastic body, and accordingly, the dimension in the vertical direction Z of the luggage storage portion. Can be made compact.

  Further, as a conventional countermeasure against collapse of the load, a technique of winding a stretch film around a plurality of articles Wa on the pallet Wb is known, but this technique requires a stretch film winding process and a removing process. In this respect, according to the shelf facility 10 of the embodiment, there is an advantage in that it is possible to take measures against the collapse of cargo without going through such a separate process.

(Second Embodiment)
FIG. 9 is a view of the stopper 40 of the second embodiment as seen from the same viewpoint as FIG.
The stopper 40 of the present embodiment is different from the first embodiment in terms of the inclined surface 52. The inclined surface 52 of the stopper 40 is formed in an arc shape that protrudes obliquely downward toward the front (left side in the figure). The inclined surface 52 is formed such that a tangent line La passing through the front end 52b is substantially parallel to the vertical surface. Accordingly, the rear portion 52c of the inclined surface 52 can reduce the gradient, while the front portion 52d of the inclined surface 52 can increase the gradient. The gradient here refers to a gradient with respect to a horizontal plane.

  If the slope of the rear portion 52c of the inclined surface 52 is large, the load W cannot be raised along the inclined surface 52 when the load W on the load receiving member 38 comes into contact with the inclined surface 52 of the stopper 40. It becomes difficult to alleviate the impact of the luggage W due to the collision with the stopper 40. On the other hand, if the slope of the front portion 52d of the inclined surface 52 is small, it is necessary to increase the longitudinal dimension and the vertical dimension of the inclined surface 52 in order to enhance the effect of preventing the luggage W from jumping out from the luggage entrance 21. When the front and rear dimensions and the vertical dimension of the inclined surface 52 become longer, it becomes necessary to increase the front and rear dimensions and the vertical dimension of the luggage storage unit 20, thereby increasing the size of the entire shelf facility 10.

  In this regard, if the inclined surface 52 is formed in an arc shape, since the gradient of the rear portion 52c of the inclined surface 52 is small, the load W on the load receiving member 38 is inclined when it comes into contact with the inclined surface 52 of the stopper 40. It becomes easy to raise the load W along the surface 52, and an impact relaxation effect can be obtained stably. Further, since the slope of the front portion 52d of the inclined surface 52 is large, the effect of preventing the luggage W from jumping out can be enhanced while shortening the front-rear dimension and the vertical dimension.

  In addition, since the slope of the front portion 52d of the inclined surface 52 is large, when a part of the load W is placed on the front portion 52d, it becomes easy to return the load W to the rear side by its own weight. It becomes easy to continuously obtain the load collapse prevention effect by the inclined surface 52 of the stopper 40.

  In the above, the example of embodiment of this invention was demonstrated in detail. The above-described embodiments are merely specific examples for carrying out the present invention. The embodiments do not limit the technical scope of the present invention, and many modifications can be made without departing from the spirit of the invention defined in the claims. Moreover, the hatching given to the cross section of drawing does not limit the material of the hatched object.

  The example in which the cargo receiving member 38 is configured by a pair of the cargo receiving members 38 that are individually attached to the two pairs of columns 28 and 30 adjacent in the left-right direction Y has been described. In addition to this, a single cargo receiving member 38 attached to two sets of struts 28 and 30 adjacent in the left-right direction Y may be used.

  In the embodiment, the example in which the stopper 40 is configured by a member different from the cargo receiving member 38 has been described. However, the stopper 40 may be configured by the same member as the cargo receiving member 38.

  In the embodiment, an example in which all the luggage storage units 20 have the stoppers 40 has been described, but at least one of the plurality of luggage storage units 20 may have the stoppers 40.

  The inclined surface 52 of the stopper 40 only needs to be formed so as to gradually become higher than the placement surface 36 of the load receiving member 38 toward the front side, and the specific shape is limited to that of the above-described example. I can't.
