Description

  The present invention includes an article storage shelf that stores articles, an article transport device that transports articles to the article storage shelf, and a control unit that controls the operation of the article transport device. A plurality of article support sections arranged side by side in the direction, and the article support section can support a plurality of articles arranged in the width direction from below, and is supported by a plurality of support posts standing apart in the width direction. The present invention relates to an article storage facility.

  As such an article storage facility, for example, as shown in Japanese Patent Application Laid-Open No. 2005-138955 (Patent Document 1), an article support unit capable of supporting an article at an arbitrary position between a pair of columns arranged in the width direction. There is something with.

JP 2005-138955 A

  In an article storage facility such as Patent Document 1, a fluid outlet (sprinkler or the like) that jets a fire-extinguishing fluid such as fire-extinguishing water or carbon dioxide gas to an article storage shelf in preparation for a fire in an article to be stored ) May be installed.

  Patent Document 1 does not describe a specific configuration of the article support unit, but the article support unit in the article storage facility is configured by a plate-like body that does not have a through-hole penetrating in the vertical direction. There is. In this case, since the fire-extinguishing fluid cannot flow smoothly in the vertical direction at the place where the article support portion exists in a plan view, a plurality of fluid ejection ports are provided in the vertical direction corresponding to each of the article support portions arranged in the vertical direction. There is a need. For this reason, the configuration of the fire extinguishing apparatus is complicated.

  In order to reduce the number of fluid ejection ports in the vertical direction, it is conceivable that each of the plurality of article support portions has a through portion that passes through the vertical direction and through which the fire-extinguishing fluid can flow. However, in the article storage facility of Patent Document 1, there may be a problem even if an article support portion having a penetrating portion is used, as will be described below.

  The article storage shelf in the article storage facility of Patent Document 1 is configured to be able to support an article at an arbitrary position in a unit storage area formed between a pair of struts adjacent in the width direction. And the control part manages the dimension (it calls an empty area dimension) of the width direction of the area | region where articles | goods are not supported about each unit storage area. When the storage of the article in the article storage shelf is instructed, the control unit stores the unit that can support the article based on the width direction dimension of the article (referred to as the article width) and the empty area dimension. The area is searched, and the operation of the article conveying apparatus is controlled so that the article is supported in the unit storage area so that the gap between the adjacent articles is a predetermined interval.

  Each time the storage of an article is commanded, the control unit determines in which unit storage area the article is stored based on the article width of the article and the empty area dimensions in the plurality of unit storage areas. For this reason, a state in which a plurality of types of articles having different dimensions in the width direction are mixedly stored in the same unit storage region may occur.

  However, when a plurality of types of articles having different dimensions in the width direction are mixedly stored in the same unit storage area as described above, the structure has a through portion that penetrates the article support portion in the vertical direction. Even if the article support part is one stage below the article support part below the fire extinguishing fluid that is ejected from the fluid outlet corresponding to the article support part in the upper stage and flows downward from the through hole of the article support part. If the supported article exists, the article may become an obstacle and the fire fighting fluid may not flow smoothly downward. For this reason, it is necessary to provide a plurality of fluid ejection ports in the vertical direction. For this reason, it is necessary to provide a plurality of fluid ejection ports in the vertical direction corresponding to each of the plurality of article support portions, which complicates the configuration of the fire extinguishing apparatus.

  Then, when installing a fire extinguishing apparatus, the article | item storage facility which can suppress that the said fire extinguishing apparatus becomes complicated is desired.

An article storage facility according to the present invention for solving the above-described problems includes an article storage shelf that stores articles, an article transport device that transports articles to the article storage shelf, and a control unit that controls the operation of the article transport device. The article storage shelf includes a plurality of article support portions arranged in a vertical direction, and the article support portion can support a plurality of articles arranged in the width direction from below and in the width direction. It is supported by a plurality of struts standing upright apart,
The article includes a plurality of types of articles classified by the dimension in the width direction, each of the article support portions includes a penetrating portion penetrating in the vertical direction, and the control unit is provided in the article support portion. Storage position determination for determining the storage position of the article in the unit storage area, where a unit storage area is an area formed between a pair of struts adjacent to each other in the width direction. Control the article transport device to store the article in the storage position determined in the storage position determination process, and in the storage position determination process, the width direction in the unit storage area The single or plural article non-existing regions where the article does not occupy a space are at the same position in the width direction with respect to the plurality of article support parts arranged in the vertical direction and at positions overlapping the penetrating part when viewed in the vertical direction. Characterized in that determining the storage position of the article to be made.

That is, in a unit storage area formed between a pair of struts adjacent in the width direction, a single or a plurality of article absence areas are formed at the same position in the width direction for a plurality of article support portions arranged in the vertical direction. The
Since the article non-existing region is formed at a position overlapping with the penetrating portion when viewed in the vertical direction, for example, the article non-existing region is provided with a fluid ejection port (for example, a sprinkler) that ejects a fire-extinguishing fluid and is ejected from the fluid ejection port. When the fire extinguishing device that extinguishes the article with the fire extinguishing fluid is provided, it becomes possible for the fire extinguishing fluid ejected from the fluid ejection port to smoothly flow from the upper part to the lower part through the penetration part of the article absent region.

  For this reason, the fire-extinguishing fluid ejected to the upper article support in the up-down direction can reach the lower article support, and the number of fluid outlets installed in the up-down direction can be reduced. Can be reduced. Therefore, when installing a fire extinguishing apparatus, it becomes possible to suppress that the fire extinguishing apparatus becomes complicated.

  In the article storage facility according to the present invention, it is preferable that a fluid ejection port for ejecting a fire-extinguishing fluid is provided above the article storage shelf.

  In other words, the fire-extinguishing fluid ejected from the fluid ejection port provided above the article storage shelf flows favorably from the uppermost stage to the lowermost stage of the article support lined up and down through the through-hole of the article absence region. For this reason, it is not necessary to arrange a plurality of fluid jet outlets corresponding to each stage of the article storage shelf, and the configuration of the fire extinguishing apparatus can be simplified.

  In the article storage facility according to the present invention, the fluid ejection port is disposed at a position overlapping with the article absence region in the vertical direction, and the fluid ejection port lowers at least a part of the fire-extinguishing fluid. It is preferable to eject toward

  That is, a part of the fire-extinguishing fluid ejected from the fluid ejection port is ejected toward the article non-existence region of the article support portion located immediately below. For this reason, the fire-extinguishing fluid ejected from the fluid ejection port flows efficiently and satisfactorily from the uppermost stage to the lowermost stage of the article support lined up and down through the penetration part of the article absence region. For this reason, it is not necessary to arrange a plurality of fluid jet outlets corresponding to each stage of the article storage shelf, and the configuration of the fire extinguishing apparatus can be simplified.

  In the article storage facility according to the present invention, the control unit sets the unit storage area as a plurality of small storage areas divided in the width direction by the article absence area, and the control unit further includes: In the storage position determination process, it is preferable that the articles stored in the small storage area are limited to articles of the same type as the articles initially stored in the small storage area.

  That is, when the article storage shelf is configured to be able to support an article at an arbitrary position with respect to a unit storage area formed between a pair of struts adjacent in the width direction, the unit storage area is defined by the article absence area. Since it is set as a plurality of small storage areas divided in the width direction, an article non-existence area can be reliably formed in the unit storage area.

  Further, since the articles stored in the small storage area are limited to the same type of articles as the articles initially stored in the small storage area, it can be determined by simple processing whether or not the articles can be stored in the small storage area. In other words, since only articles of the same type (for example, a type based on the article width) are stored in the small storage area, the number that can be stored in the small storage area is determined for each type of article. For this reason, for example, the control unit manages the empty area size of the small storage area, and performs small storage without performing a complicated process of determining whether the article can be stored based on the empty area size and the article width. Only by managing the type and number of articles stored in the area, it is possible to determine whether or not the articles can be stored in the small storage area, and the control configuration can be simplified.

  Next, based on FIG. 5, the control configuration of the article storage facility of the present embodiment will be described. The control part H is comprised by the computer provided with the arithmetic unit and the memory | storage device, for example, and performs various control by running the program memorize | stored in the memory | storage device.

  The control unit H is configured to be able to communicate with the management apparatus K via a wired LAN or a wireless LAN. The management device K is composed of, for example, a computer including an arithmetic device and a storage device, manages the entry / exit of the item B with respect to the item storage shelf T, and instructs the control unit H to enter / exit the item B. .

  As shown in FIG. 4, the control unit H stores an area formed between a pair of struts 11 adjacent to each other in the width direction X, in which the article B supported by the article support unit TS is stored. As the area At, a storage position determination process for determining the storage position of the article B in the unit storage area At is executed. In the storage position determination process, the article support unit TS that stores the article B is determined, and when the article B already exists in the unit storage area At, the distance to the adjacent article B is the width direction X. The position of the article B to be stored is determined in such a manner that the article B is separated by a width that allows the pair of holding bodies of the transfer device 26 to enter.

  Further, as shown in FIG. 4, the control unit H, in the storage position determination process, includes a plurality of article nonexistent areas A2 in which the article B does not occupy space in the width direction X in the unit storage area At. The storage position of the article B is determined so that the article support portion TS is formed at the same position in the width direction X and overlapping with the penetrating portion when viewed in the vertical direction. In the present embodiment, the jet outlet Ps is arranged at a position overlapping the article non-existing region A2 in plan view, and the jet outlet Ps is set to jet out at least a part of fire-extinguishing water downward. Yes.

  The stacker crane 20 includes a controller 20 </ b> C that controls the operation of its own traveling motor 24, lifting motor 25, and transfer device 26. When the control unit H instructs the stacker crane 20 to transport the article B to the position determined in the storage position determination process (referred to as a determined position), the controller 20C moves to the travel position corresponding to the determined position. The traveling motor 24 is controlled so as to move the traveling unit 21, and the lifting motor 25 is controlled so that the lifting body 23 is positioned at a height corresponding to the article support unit TS that stores the article B. Then, at the determined position, the transfer device 26 is controlled so that the article B supported by the elevating body 23 is transferred to the article support part TS. That is, the control unit H controls the stacker crane 20 to store the article B in the storage position determined by the storage position determination process.

  Further, the control unit H manages the article B by classifying the article B into a plurality of types based on the dimensions in the width direction X. Specifically, the first type article B1, the second type article B2, the third type article B3, and the fourth type article B4 are managed in order from the smaller dimension in the width direction X (see FIG. 4). That is, as the articles B to be stored, a plurality of types of articles B (first-type articles B1, second-type articles B2, third-type articles B3, and fourth-type articles B4) classified by dimensions in the width direction X are included. It is. Note that the type of the article B is not limited to the above four types, and may be three types or less, or five or more types.

  As shown in FIG. 4, the control unit H sets the unit storage area At as a plurality of small storage areas A1 divided in the width direction X by the article non-existence area A2, and in the storage position determination process The articles B stored in the small storage area A1 are limited to the same types of articles B as the articles B initially stored in the small storage area A1. For example, as shown in FIG. 3, the control unit H sets the number of articles B that can be stored in the small storage area A1 to five for the first type article B1 and about the second type article B2. Management is performed for each type of article B, such as four, three for the third type article B3, and two for the fourth type article B4. In the following description, the number of articles B that can be stored in the small storage area A1 is referred to as a “storable number”.

  Next, the control executed by the control unit H will be described based on the flowchart of FIG. When the control unit H is instructed to store the article B from the management apparatus K (step # 1: Yes), the type information (first type article B1, first article B1, A second type article B2, a third type article B3, or a fourth type article B4) is acquired (step # 2). The method for acquiring the type information by the control unit H may be a mode in which the control unit H transmits a notification request to the management device K, and the management device K transmits the type information to the control unit H as a response to the request. The management device K may transmit the type information of the article B to the control unit H together with an instruction to store the article B.

  Subsequently, the control unit H determines whether or not there is a small storage area A1 that stores an article B having the same type information as the storage target article (step # 3). If the control unit H determines that there is a small storage area A1 that stores an article B of the same type information as the storage target article (step # 3: Yes), the control unit H determines the number of articles B that are already stored in the small storage area A1. Based on the storable number of the small storage area A1, it is determined whether or not a storage target article can be stored in the small storage area A1 (step # 4). Note that the processing of step # 3 and step # 4 is executed until a small storage area A1 in which the storage target article can be stored is found.

  When the control unit H determines that there is a small storage area A1 that is set for the same type as the storage target article and can store the storage target article (step # 4: Yes), the small storage with respect to the stacker crane 20 is performed. In step A5, the storage target article is instructed to be transported to the determined position determined in the position determination process in the area A1 (step # 5), and the flow ends.

  On the other hand, the control unit H determines that there is no small storage area A1 storing the article B of the same type information as the storage target article (step # 3: No), or stores the storage target article in the small storage area A1. If it is determined that it cannot be stored (step # 4: No), subsequently, it is determined whether or not the small storage area A1 that is empty (no article B is supported) exists in the article storage shelf T. Discriminate (step # 6).

If the control unit H determines that the article storage shelf T is empty (step # 6: Yes), then, the control unit H sets the small storage area A1 to be limited to the same type as the articles to be stored (step # 7). Then, the process proceeds to step # 5.
On the other hand, when the control unit H determines that there is no space in the article storage shelf T (step # 6: No), the control unit H activates or manages a warning lamp to notify that the storage area in the article storage shelf T is full. A message to that effect is displayed on the display screen of the device K or the control unit H (step # 8), and the flow ends.

  Thereby, in the article storage facility of the present embodiment, the storage positions of a plurality of types of articles B having different dimensions in the width direction X can be easily managed, and a plurality of items arranged in the vertical direction in the article storage shelf T. Since the article absence region A2 is formed at the same position in the width direction X for each of the article support portions TS, as shown in FIGS. 4 and 7, a communication space Aa along the vertical direction can be formed. Therefore, as shown in FIG. 7, the fire-fighting water ejected from the sprinkler spout Ps can reach the position of the first-stage article support part TS1 in the vertical direction through the communication space Aa, and is positioned downward in the vertical direction. Even if the article B supported by the article support unit TS to be ignited, an article storage facility that can easily extinguish the ignited article B can be provided.

A plurality of height positions at T (for example, a position that is above the fourth stage article support part TS4 in the vertical direction and a position that is above the second stage article support part TS2 in the vertical direction) and the width direction X Thus, the spout Ps may be provided at a position corresponding to the article absence region A2. Also in this case, since the article absence area A2 of each of the plurality of article support portions TS arranged in the vertical direction is formed at the same position in the width direction X, the article absence area A2 communicates in the vertical direction, and the upper stage Since the fire-extinguishing water passes from the article support part TS on the lower side to the article support part TS on the lower side, the fired article B that has been properly ignited can be extinguished even with a small number of jets Ps.

(5) In the above embodiment, in the storage position determination process, the article B stored in the small storage area A1 is limited to the same type of article B as the article B initially stored in the small storage area A1. The type of the article B stored in the small storage area A1 may not be limited to one. In this case, the control unit H manages the dimension in the width direction X of an area where the article B is not located (referred to as an empty area) in the small storage area A1, and the control unit H receives the article B from the management device K. When instructed, the size in the width direction of the article B (article width) is acquired from the management device K, and whether or not the article B can be stored in the empty area is determined from the article width and the dimension of the empty area. You may comprise as follows.

(6) In the above-described embodiment, the article storage shelf T is configured to be installed so that the article support part TS and the jet outlet Ps overlap with each other when viewed in the vertical direction. However, the article support part TS and the jet outlet are illustrated. The article storage shelves T may be arranged so that Ps does not overlap with the vertical view. Also in this case, it is preferable to arrange the article storage shelf T so that the article non-existence area A2 is below the jet outlet Ps when viewed in the depth direction Y.
Moreover, although the example which arrange | positions the jet nozzle Ps in the position which overlaps with the article | item non-existence area | region A2 by planar view was shown in the said embodiment, the jet nozzle Ps does not overlap with the article | item absent area | region A2 by planar view. You may arrange in a position. In this case, it is desirable to set the ejection direction of the fire-extinguishing water from the ejection port Ps so that the fire-extinguishing water is ejected toward the article absence area A2 of the uppermost article support part TS in the article storage shelf T.

(7) Although the automatic warehouse which provided the stacker crane as an article conveyance apparatus was illustrated in the said embodiment, things other than a stacker crane may be used for an article conveyance apparatus. For example, it is conceivable to provide an article conveying apparatus including an article conveying movable body that travels in the width direction for each stage of the article support section.
