Even after the upper surface of the storage target article comes into contact with the bottom surface of the storage article, the storage target article is further raised so that the storage target article supports the storage article. In this state, the support that has supported the stored article is not subjected to a load from the stored article. That is, the supported part of the stored article and the support are in a state of being separated in the vertical direction. In this state, the support is moved to the retracted position, and then the article to be stored is raised to the height of the support by the lifting device. The article to be stored is raised to the height of the support, the support in the retracted position is moved to the support position, and the article to be stored is supported by the support. Thus, the facility of Patent Document 1 stores a plurality of articles in a stacked state.

Japanese Patent Application Laid-Open No. 5-254662

  If the number of stacks of articles stored in the facility as in Patent Document 1 is large, the load received by the lowest article increases. When a plurality of stacked articles have the same shape and are stacked in a completely overlapping state (positioned at the same position) in plan view, the article has a thick part and a thin part In order to stack the articles through the state in which the articles to be stored support the stored articles as described above, it is necessary for the support to support the thin portion of the lowermost article. In addition, when the plurality of stacked articles have the same shape and are in the same position in plan view, a gap is formed between the thin portions of each article. Therefore, if the load of the laminated article is supported by the support in the thin portion of the lowermost article, the lower article may be deformed, and it is difficult to store a plurality of articles in a laminated state. .

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an article storage facility capable of stacking and storing articles having thin portions in a state where deformation is unlikely to occur. is there.

  In order to solve the above problems, the characteristic configuration of the article storage facility according to the present invention includes a support body that is disposed at a position spaced upward from the floor surface and supports a supported portion on the bottom surface of the article, and a preparation position for raising and lowering from the outside. An elevating device that moves up and down between a receiving height for receiving the article supplied to the support and a delivery height for delivering the article to the support, and the receiving height is provided on the support. The delivery height is lower than the height of the article that is directly supported, and the delivery height is higher than the height of the article that is directly supported by the support. It is configured to be switchable between an overlapped support position and a retreat position where the whole is located outside the article, and a plurality of articles having the same shape are in the same posture by the lifting and lowering operations of the lifting device and the switching operation of the support. An article storage facility for storing in a layered state, wherein articles are arranged in a line-up direction along a horizontal plane with a thin-walled portion having a narrow vertical width and a thick-walled portion having a vertical width wider than the thin-walled portion. The horizontal movement device further includes a horizontal movement device that moves the articles in the arrangement direction, and the horizontal movement device overlaps the thick portions of the plurality of articles stored in a stacked state in the arrangement direction. And it exists in the point comprised so that an article may be moved to the position where this overlapping length becomes shorter than the length of the said alignment direction of the said thick part in the said alignment direction.

  According to this configuration, when storing a plurality of articles having a thin-walled portion and a thick-walled portion aligned in the alignment direction along the horizontal plane, the articles can be moved in the alignment direction by the horizontal movement device. it can. Therefore, the horizontal movement device is configured so that the thick portions of the plurality of articles stored in the stacked state overlap in the arrangement direction, and the overlapping length is longer than the length in the arrangement direction of the thick portions. Articles can be moved in the alignment direction so as to be shorter. When a plurality of articles are laminated in such a state, each of the plurality of laminated articles is supported by an article positioned immediately below the thick portion having high strength. Therefore, according to this structure, it becomes possible to laminate | stack the article | item which has a thin part, and to store it in the state which is hard to produce a deformation | transformation.

  Further, the horizontal movement device is configured to place the article in the arrangement direction so that a part of the thick portion of the article directly supported by the support is located at a position overlapping the support in the arrangement direction. It is suitable if it is comprised so that it may move by.

  According to this configuration, the article directly supported by the support can have the thick part supported by the support. Therefore, according to this configuration, it is possible to suppress the deformation of the article supported by the article located directly below the plurality of stacked articles and the lowest article supported by the support. Further, since the position of the support is configured to overlap with a part of the thick part of the article directly supported by the support, the part of the directly supported article is supported. While being supported by the body, the other part can be supported by the article rising from below the directly supported article. That is, conventionally, the stacked articles have the same shape and are stacked so as to be completely overlapped in a plan view. When the article is supported by the support, the article rising from below the directly supported article interferes with the support and supports the thick part of the article supported directly by the support. become unable. However, according to the present configuration, any of a plurality of stacked articles can be supported by the thick portion.

  Preferably, the horizontal movement device is configured to move up and down integrally with the lifting device, and the operation of the horizontal movement device and the operation of the lifting device are configured to overlap at least for a certain period. It is.

  According to this configuration, when stacking the plurality of articles such that the thick portions of the plurality of articles overlap in the arrangement direction, the lifting of the article by the lifting device and the horizontal movement of the article by the horizontal movement device are performed. Since the process can proceed at the same time for at least a certain period, the working time can be shortened.

  The article storage facility according to the present invention preferably includes a transport device that transports the article in a direction orthogonal to the arrangement direction along a horizontal plane and supplies the article from the outside to the lifting preparation position. It is.

  According to this configuration, the article can be supplied to the lifting preparation position by conveying the article by the conveying device, and the labor of supplying the article manually can be reduced.

  The support includes a first support and a second support, and each of the first support and the second support is configured to be switchable between the support position and the retracted position, and It is preferable that the support position of the first support member and the support position of the second support member are configured to be different in the arrangement direction.

  According to this configuration, when stacking a plurality of articles in a state where the plurality of articles are alternately arranged at two positions different in the arrangement direction, the support for supporting the lowest article in the plurality of stacked articles is supported. By alternately using the first support and the second support that are in different positions in the alignment direction as a body, the step of moving the entire stacked article in the alignment direction can be omitted. Thereby, shortening of work time can be aimed at.

Then, one of the pair of chain sprockets 23 is driven by a conveying motor (not shown), and the chain 24 operates. By operating the chain 24, the driving force of the conveying motor is transmitted to the other chain sprocket 23, whereby the other chain sprocket 23 is driven. The transport device 2 has a pair of such configurations in a state of being separated in the arrangement direction X. As a result, the transport device 2 is configured to be able to transport the article 7 along the transport direction Y in a state in which the vicinity of both ends in the arrangement direction X of the articles 7 is supported. As shown in FIG. 1, the receiving height H <b> 1 at which the lifting device 3 receives the article 7 from the transport device 2 is set to a height at which the chain 24 of the transport device 2 is disposed.

  As shown in FIG. 1, the lifting device 3 is configured to receive the article 7 from the transport device 2 at the lifting preparation position RP. The lifting device 3 is disposed below the receiving height H1 at the lifting preparation position RP. The elevating device 3 includes a base 31 provided on the floor, a first elevating unit 32 that is inserted into the base 31 from the vertical direction and moves up and down relatively with respect to the base 31, and a first from the vertical direction. And a second elevating unit 33 that is inserted into the first elevating unit 32 and is moved up and down relatively with respect to the first elevating unit 32. The elevating device 3 is configured to be able to move up and down the first elevating unit 32 and the second elevating unit 33 by being driven by a hydraulic cylinder (not shown).

  As shown in FIG. 1, the support 51 is configured to be able to support the supported portion 71 of the article 7 at a position spaced upward from the floor surface. As shown in FIGS. 1 and 2, four frames 8 are erected around the elevating device 3. Each of the four frames 8 is provided with a bracket 6 formed in an angular U shape when viewed from the transport direction Y. A vertical shaft 52 along the vertical direction is rotatably attached to the bracket 6 via a bearing (not shown).

The support body 51 is provided in a posture along a direction orthogonal to the arm 50 in the horizontal plane. That is, the arm 50 and the support body 51 are integrally formed so as to be L-shaped in plan view. The support 51 is configured to be switchable between a support position SP at least partially overlapping the article 7 when viewed in the vertical direction and a retracted position EP located entirely outside the article 7 (see FIG. 2). . Specifically, the support position SP refers to a position where at least a part of the support 51 overlaps the article 7 arranged in the vertical direction where the lifting preparation position RP is positioned when viewed in the vertical direction. The retreat position EP refers to a position where the entire support 51 does not overlap the article 7 when viewed in the vertical direction. When the vertical shaft 52 is rotated by the turning motor 53 provided on the upper portion of the bracket 6, the arm 50 and the support body 51 attached to the vertical shaft 52 are turned in the horizontal plane around the vertical shaft 52. Thereby, the support body 51 can be switched between the support position SP and the retracted position EP. The article storage facility 1 can store a plurality of articles 7 having the same shape in the same posture and in a stacked state by the lifting operation of the lifting device 3 and the switching operation of the support 51.

  As described above, the article 7 to be stored by the article storage facility 1 according to the present embodiment is a pallet. As shown in FIG. 3, the article 7 is formed in a substantially plate shape. Both end portions in the arrangement direction X of the articles 7 have a shape protruding upward along the conveyance direction Y (see also FIG. 2). This protruding portion becomes the thick portion 74. The portion other than the thick portion 74 in the article 7 becomes the thin portion 73. Since the article 7 is a pallet made of an iron plate and is a heavy article, a large load is applied to the article 7 when a plurality of articles 7 are stacked. In this case, when the thin-walled portion 73 having a low strength is supported for the article 7, the article 7 may bend around the supported portion due to the influence of the load. When the article 7 is bent, it is difficult to store a plurality of articles 7 in a stacked manner. Therefore, in this embodiment, since all of the plurality of articles 7 to be stacked are supported by the thick portion 74, the articles 7 are configured to be stacked while being moved in the alignment direction X.

  That is, as shown in FIGS. 1 and 2, the article storage facility 1 according to the present embodiment further includes a horizontal movement device 4 that moves the articles 7 in the arrangement direction X. The horizontal movement device 4 is configured by a belt 43 being wound around a pair of belt sprockets 42 which are provided in the box-like frame 41 so as to be separated from each other along the alignment direction X. Then, one of the pair of belt sprockets 42 is driven by a moving motor (not shown), and the belt 43 operates. By the operation of the belt 43, the driving force of the moving motor is transmitted to the other belt sprocket 42, whereby the other belt sprocket 42 is driven. For this reason, the horizontal movement device 4 can move the article 7 in the arrangement direction X in a state where the article 7 is placed on the belt 43. In the present embodiment, the horizontal movement device 4 is configured such that the thick portions 74 of the plurality of articles 7 stored in the stacked state overlap in the alignment direction X, and the overlapping length is the thickness of the thick portion 74. The article 7 is configured to move in the arrangement direction X to a position that is shorter than the length in the arrangement direction X. With such a configuration, all of the plurality of articles 7 stored in a stacked state can be supported by the thick portion 74. Therefore, according to this embodiment, it can suppress that the problem on the intensity | strength of the articles | goods 7 arises. In the present embodiment, the horizontal movement device 4 is configured to move the articles 7 so as to arrange the plurality of articles 7 stored in a stacked state in a zigzag manner along the vertical direction. For example, even if the plurality of articles 7 are stacked so that the plurality of articles 7 stored in a stacked state are supported by the thick portion 74, all of the plurality of articles 7 are arranged in the same direction. If it is, the balance of the entire article 7 to be laminated is deteriorated. In this case, there is a high possibility that the plurality of stacked articles 7 will collapse. However, when the horizontal movement device 4 is configured to move the articles 7 such that the plurality of articles 7 are arranged in a zigzag manner along the vertical direction as in the present embodiment, they are stacked. Good balance of the entire article 7 can be maintained.

  As shown in FIG. 6 and the like, the upper surface of the thick part 74 of the article 7 is a support part 72, and an arbitrary article 7 of the plurality of articles 7 to be stacked is arranged directly above this. The article 7 is supported by the support portion 72. Furthermore, the bottom surface of the thin portion 73 of the article 7 is a supported part 71, and the arbitrary article 7 is configured such that the supported part 71 is supported by another article 7 disposed immediately below the supported part 71. Has been. And the article 7 (hereinafter referred to as the lowest article 7) located in the lowest stage among the plurality of articles 7 stored in the stacked state is configured such that the supported portion 71 is supported by the support body 51. Yes. Here, for example, when the entire supported portion 71 of the lowermost article 7 is supported by the support body 51, the article to be stored that is raised by the lifting device 3 from below the lowermost article 7. 7 (hereinafter referred to as the storage object 7) cannot support the supported portion 71 of the lowermost article 7. Therefore, in the present embodiment, the horizontal movement device 4 arranges the articles 7 in the arrangement direction so that a part of the thick portion 74 of the lowermost article 7 overlaps the support body 51 in the arrangement direction X. It is comprised so that it may move by X. As a result, the lowermost article 7 can be supported by the support body 51 in the thick portion 74 that overlaps the support body 51 in the alignment direction X, and the other portion of the thick wall portion 74 is stored. It can be supported by the target article 7. The lowermost article 7 corresponds to “an article directly supported by a support”. In the following description, articles 7 that have already been stored, including the lowest article 7, may be described as stored articles 7.

  As shown in FIGS. 1 and 2, the horizontal movement device 4 is configured to move up and down integrally with the lifting device 3. That is, the horizontal movement device 4 is provided on the upper portion of the lifting device 3. As a result, the horizontal movement device 4 is also moved up and down as the lifting device 3 moves up and down. In the present embodiment, “the lifting device supports the article supplied to the lifting preparation position from below” means that the article 7 is indirectly supported via the horizontal movement device 4. Moreover, in this embodiment, it is comprised so that the operation | movement of these horizontal movement apparatuses 4 and the operation | movement of the raising / lowering apparatus 3 may overlap at least for a fixed period. Accordingly, the article 7 can be moved up and down and horizontally moved along the alignment direction X at least simultaneously for a certain period. Therefore, the work time of the entire storage work can be shortened compared with the case where the article 7 performs these operations separately for different periods.

  Next, the operation of the article storage facility 1 will be described with reference to FIGS. # 1 to # 10 shown in FIGS. 3 to 7 are first to tenth regions obtained by dividing a region along the vertical direction in the arrangement direction X.
