[0100] In the rack system 10, the first rack is always present no matter where the movable racks (rack 100B, rack 100C, rack 100D) are moved. Note that the configuration of the rack system 10 is not limited to the configurations of the rack system 10 in Fig. 1 and Fig. 4 to Fig. 19. Various configurations can be realized by the movable rack being guided and slid by the first guide rail 171A and the first guide rail 171B.

[0101] (2-2-2-2) Control based on termination information When the completion information is received, the movement control unit 192 moves the racks 100B, 100C, and 100D in a direction substantially perpendicular to the front wall 11 so that the state of the rack system 10 in Fig. 1 and Fig. 4 to Fig. 9 is realized after the first work is completed.

[0103] (3) Operation The operation of the facility 1 when a person or device performs a first task will be described. The first task is performed in the order of rack 100A, rack 100B, rack 100C, rack 100D, and rack 100E. Fig. 21 is a flowchart showing the operation of the facility 1. The embodiment of the rack system 10 is the embodiment of the rack system 10 in Figs. 1 and 4 to 9.

[0104] Heated air is supplied to the interior I1 through the opening O. Therefore, the interior I1 maintains a higher temperature than the outside of the plant factory 1000. The interior I1 has an environment suitable for growing plants P.

[0105] Aisle A for rack 100A has already been secured. A person or device moves to the front of rack 100A through entrance / exit 121 and aisle A. The person or device starts a first task on rack 100A. After the first task on rack 100A is completed, the person or device starts a first task on rack 100B, since aisle A for rack 100B has already been secured. After the first task on rack 100B is completed, the person or device leaves aisle A.

[0106] A person or device inputs work information indicating that the target of the first work is rack 100C to the control device 19. The reception unit 191 receives the work information indicating that the target of the first work is rack 100C. The movement control unit 192 moves rack 100B and rack 100C in approximately the negative X direction (step S1). In this way, the movement control unit 192 realizes the aspects of the rack system 10 in FIGS. 10 to 14.

[0107] A person or device moves to the front of rack 100C via aisle A. The person or device starts a first task on rack 100C. After the first task on rack 100C is completed, the person or device starts a first task on rack 100D because aisle A for rack 100D has already been secured. After the first task on rack 100D is completed, the person or device leaves aisle A.

[0108] A person or device inputs work information indicating that the target of the first work is rack 100E to the control device 19. The reception unit 191 receives the work information indicating that the target of the first work is rack 100E. The movement control unit 192 moves the rack 100D in approximately the negative X direction (step S2). In this way, the movement control unit 192 realizes the aspects of the rack system 10 in FIGS. 15 to 19.

[0109] The person or the device moves behind the rack 100E through the aisle A. The person or the device starts a first operation on the rack 100E. After the first operation on the rack 100E is completed, the person or the device leaves the aisle A.

[0110] A person or device inputs end information to the control device 19. The reception unit 191 receives the end information. The movement control unit 192 moves rack 100B, rack 100C, and rack 100D approximately in the X direction (step S3). In this way, the movement control unit 192 realizes the aspects of the rack system 10 in FIG. 1 and FIG. 4 to FIG. 9. The opening O no longer faces the five racks (rack 100A, rack 100B, rack 100C, rack 100D, and rack 100E).

[0111] (4) Features (4-1) The rack system 10 includes three or more racks (rack 100A, rack 100B, rack 100C, rack 100D, rack 100E) on which a plant P is cultivated. The racks are present inside I1 of another structure and are approximately parallel to a first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move approximately perpendicularly to the first vertical wall. Even if the movable rack is moved approximately perpendicularly to the first vertical wall, at least one of the three or more racks is a first rack that is a rack in which an aisle A that is approximately parallel to the first vertical wall is not secured, which is a passage A used by a person or a device when a first task, which is a task of a person or a device on a plant P, is performed. By moving the movable rack approximately perpendicularly to the first vertical wall, one or more of the three or more racks are changed to a second rack that is a rack in which an aisle A is secured.

[0112] Racks are used inside the structure on which plants are grown. Plant cultivation requires human or equipment work on the plants. Inside the structure, passages are provided for human or equipment work. Therefore, a large amount of space is taken up by the passages inside the structure, and the space available for plant cultivation is reduced. This increases the space cost for plant cultivation. Also, to make the inside of the structure an environment suitable for plant cultivation, air conditioning is performed inside the structure. The amount of energy required for air conditioning is correlated with the volume. A wide passage inside the structure increases the amount of energy required for plant cultivation. This increases the air conditioning cost for plant cultivation.

[0113] In the rack system 10, no matter where the movable rack is moved, there are racks for which aisle A is not secured. Since there are racks for which aisle A is not secured, the rack system 10 can achieve space saving for aisle A. As a result, the rack system 10 can achieve space and energy saving for the cultivation of the plant P.

[0114] In the rack system 10, the first rack is changed into the second rack by moving the movable rack. This allows the rack system 10 to secure the aisle A for the first rack as well, making it possible to perform the first work on the plants P.

[0115] The racks of the rack system 10 (rack 100A, rack 100B, rack 100C, rack 100D, rack 100E) are approximately parallel to the first vertical wall. The movable racks are moved approximately perpendicular to the first vertical wall. This allows the rack system 10 to reduce wasted space in the interior I1 other than the racks and aisle A, even when the movable racks are moved.

[0116] (4-2) In the rack system 10, when one or more first racks among the three or more racks are changed to a second rack by moving the movable rack in a direction approximately perpendicular to the first vertical wall, one or more second racks among the three or more racks are changed to the first rack.

[0117] In the rack system 10, even if a first rack is changed to a second rack, the other second racks are changed to the first rack. In the rack system 10, there are racks for which an aisle A is not provided. Therefore, the rack system 10 can realize space saving for the aisle A. As a result, the rack system 10 can realize space saving and energy saving for the cultivation of the plant P.

[0118] (4-3) The rack system 10 further includes a first guide rail 171A and a first guide rail 171B that are fixed to a floor F of another structure and extend in a direction substantially perpendicular to the first vertical wall. The movable rack is guided and slid by the first guide rail 171A and the first guide rail 171B, and thereby moves in a direction substantially perpendicular to the first vertical wall.

[0119] The movable racks (rack 100B, rack 100C, rack 100D) are guided and slid by the first guide rails 171A and 171B. Therefore, the force received by the movable racks is not dispersed, and the movable racks are efficiently moved in a direction substantially perpendicular to the first vertical wall. This makes it easier for the rack system 10 to ensure the passage A for each rack.

[0120] (4-4) In the rack system 10, a rack that is located at the shortest distance from the first vertical wall in a direction substantially perpendicular to the first vertical wall is not a movable rack. A rack that is located at the shortest distance from the second vertical wall of another structure facing the first vertical wall in a direction substantially perpendicular to the second vertical wall is not a movable rack.

[0121] A vertical wall does not require an aisle. An aisle serves as an aisle on both sides (both sides horizontal to the direction in which people or equipment move). If an aisle is secured between the vertical wall and a rack that is at the shortest distance in a direction approximately perpendicular to the vertical wall, one side of the aisle (the vertical wall side) cannot serve as an aisle. Therefore, when the rack at the shortest distance is moved to secure the aisle, an unnecessary aisle is secured on one side. An unnecessary aisle on one side wastes space and lengthens the movement line of people or equipment when working.

[0122] In the rack system 10, the rack 100E located at the shortest distance from the front wall 11 in the approximately vertical direction is not a movable rack. Furthermore, the rack 100A located at the shortest distance from the rear wall 14 in the approximately vertical direction is also not a movable rack. Therefore, the rack system 10 can ensure an aisle A that can function as an aisle on both sides. The rack system 10 can limit the movable racks to a portion, and can shorten the movable distance of the movable racks and the movement of people or equipment. As a result, the rack system 10 can further achieve energy savings in cultivating the plants P.

[0123] (4-5) In the rack system 10, a rack that is at the shortest distance from the first vertical wall in a direction approximately vertical to the first vertical wall, and a rack that is at the shortest distance from a second vertical wall of another structure opposite the first vertical wall, are longer in the approximately horizontal direction in which the first vertical wall extends than any other rack among the three or more racks other than the rack that is at the shortest distance in the direction approximately vertical to the first vertical wall and the rack that is at the shortest distance in the direction approximately vertical to the second vertical wall.

[0124] When an aisle is provided in the space adjacent to the vertical wall, one side of the aisle is wasted. Therefore, it is desirable to utilize the space adjacent to the vertical wall as a space in which racks are located.

[0125] In the rack system 10, the racks 100A and 100E are long in the substantially horizontal direction in which the first vertical wall extends due to the racks 100B, 100C, and 100D. This allows the rack system 10 to secure a large space for cultivating the plant P in the interior I1, thereby realizing space-saving and energy-saving in cultivating the plant P.

[0126] (4-6) The control device 19 includes a movement control unit 192 that controls the movable rack in the rack system 10 so that the movable rack is moved in a direction substantially perpendicular to the first vertical wall.

[0127] It may be difficult to move a heavy or large rack by hand. Also, moving a rack takes time. The control device 19 moves the racks 100B, 100C, and 100D. Therefore, the control device 19 can move a heavy or large rack, and the time required for moving can be reduced.

[0128] (4-7) The control device 19 determines that the other structure has an opening O for supplying conditioned air. The movement control unit 192 further controls the movable rack to be moved in a direction substantially perpendicular to the first vertical wall so that three or more racks do not face the opening O after the first work is completed.

[0129] Air is blown out from the opening that supplies conditioned air. When a rack faces an opening, the degree of air conditioning may differ greatly between the periphery of the rack facing the opening and the area far from the opening. Therefore, an environment suitable for cultivation cannot be provided for plants grown on at least one of the rack facing the opening and the rack far from the opening. In addition, the air blown out from the opening may collide with the rack facing the opening, forming a distorted airflow. Therefore, temperature or humidity unevenness may occur inside.

[0130] After the first task is completed, the control device 19 moves the movable racks so that three or more racks do not face the opening O. Therefore, the control device 19 can reduce the possibility of temperature or humidity unevenness occurring, and can create an environment in the interior I1 that is more suitable for cultivating the plant P.

[0131] (4-8) The control method includes a movement control step of controlling the movable rack in the rack system 10 so that the movable rack is moved in a direction substantially perpendicular to the first vertical wall.

[0132] Therefore, when the control method is implemented, even heavy or large racks can be moved, thereby reducing the effort required for movement.

[0133] (5) Variations Regarding the modified example of the first embodiment, the description will be centered on the differences from the first embodiment and the description of the similarities to the first embodiment will be omitted.

[0134] (5-1) Variation 1A The reception unit 191 may receive movement information from a person or device via an input device (not shown). The movement information is information indicating at least one of the movement direction and movement distance of the movable racks (rack 100B, rack 100C, rack 100D) and the location to which the movable racks are to be moved. The location to which the movable racks are to be moved may be a location represented by two-dimensional coordinates in a two-dimensional coordinate system of X-axis and Z-axis or three-dimensional coordinates in a three-dimensional coordinate system of X-axis, Y-axis, and Z-axis. The reception unit 191 may receive movement information from a server or a cloud via a network.

[0135] (5-2) Variation 1B The equipment 1 may not include the control device 19. In this case, the movable rack is moved in a direction substantially perpendicular to the front wall 11 by human power.

[0136] (5-3) Variation 1C The facility 1 may include a vinyl greenhouse 2000 instead of the plant factory 1000. Fig. 22 is a perspective view showing the overall configuration of the facility 1 according to Modification 1C. The vinyl greenhouse 2000 is a structure in which a framework is assembled and the upper part is covered with vinyl or the like in order to cultivate a plant P. The plant P is cultivated inside the vinyl greenhouse 2000.

[0137] The facility 1 may include a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 2000. The vinyl greenhouse 2000 may or may not be a building.

[0138] A rack system 10 is mainly provided in the interior I2 of the vinyl greenhouse 2000. The rack system 10 is similar to the rack system 10 in any one of the first embodiment, the embodiment of Modification 1A, and the embodiment of Modification 1B.

[0139] The vinyl greenhouse 2000 mainly has a front wall 11, a left side wall 12, a right side wall 13, a rear wall 14, a ceiling 15, and one or more lights (not shown). The structures and functions of the components of the vinyl greenhouse 2000 are similar to those of the first embodiment except for the shape of the ceiling 15, and therefore will not be described.

[0140] (5-4) Variation 1D (5-4-1) Structure The facility 1 may include a mushroom cultivation facility 3000 instead of the plant factory 1000. Fig. 23 is a perspective view showing the overall configuration of the facility 1 according to Modification 1D. The mushroom cultivation facility 3000 refers to a building or a vinyl greenhouse in which mushrooms M are cultivated.

[0141] A rack system 10 is mainly provided in the interior I3 of the mushroom cultivation facility 3000. The rack system 10 is similar to the rack system 10 in any one of the first embodiment, the embodiment of Modification 1A, and the embodiment of Modification 1B, except that mushrooms M are cultivated in the rack instead of plants P.

[0142] The mushroom cultivation facility 3000 mainly has a front wall 11, a left side wall 12, a right side wall 13, a rear wall 14, a ceiling 15, and one or more lights (not shown). The structures and functions of the components of the mushroom cultivation facility 3000 are similar to those of the first embodiment, and therefore will not be described.

[0143] Mycelium bottles B are placed on five racks (rack 100A, rack 100B, rack 100C, rack 100D, rack 100E). Mushrooms M are cultivated in the mycelium bottles B. The mycelium bottles B and mushrooms M are collectively referred to as set MS. Note that the mushrooms M may be cultivated in a mushroom bed bag instead of the mycelium bottles B. Note that the mushrooms M may be cultivated on wood instead of the mycelium bottles B.

[0144] The first work is mushroom work performed by a person or a machine on mushrooms M. Examples of the mushroom work include an inoculation work for planting seed cultures of mushrooms M, a cultivation work for cultivating mushrooms M, a harvesting work for harvesting all or part of mushrooms M, and other mushroom work.

[0145] (5-4-2) Features The rack system 10 includes three or more racks on which mushrooms M are cultivated. The racks are present inside another structure and are approximately parallel to a first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move approximately perpendicularly to the first vertical wall. Even when the movable rack is moved approximately perpendicularly to the first vertical wall, at least one of the three or more racks is a first rack that is a rack in which an aisle A that is approximately parallel to the first vertical wall is not secured, which is a passage A used by a person or a device when a first task, which is a task of a person or a device on mushrooms M, is performed. By moving the movable rack approximately perpendicularly to the first vertical wall, one or more of the three or more racks are changed to a second rack that is a rack in which an aisle A is secured.

[0146] Inside the structure, racks are used for growing mushrooms. Mushroom cultivation requires human or equipment work on the mushrooms. Inside the structure, an aisle is provided for the human or equipment work. Therefore, a large amount of space is taken up by the aisle inside the structure, and the space available for mushroom cultivation is reduced. This increases the space cost for mushroom cultivation. Also, to make the inside of the structure an environment suitable for mushroom cultivation, air conditioning is performed inside the structure. The amount of energy required for air conditioning is correlated with the volume. A wide aisle inside the structure increases the amount of energy required for mushroom cultivation. This increases the air conditioning cost for mushroom cultivation.

[0147] The rack system 10 can realize space-saving and energy-saving in cultivating the mushrooms M. Furthermore, the rack system 10 can ensure an aisle A for the first rack as well, making it possible to perform the first operation on the mushrooms M.

[0148] (5-5) Variation 1E (5-5-1) Structure The facility 1 may include a warehouse 4000 instead of the plant factory 1000. Fig. 24 is a perspective view showing an overall configuration of the facility 1 according to Modification 1E. Examples of the warehouse 4000 include, but are not limited to, a normal temperature warehouse, a low temperature warehouse, a freezer warehouse, and a refrigerated warehouse.

[0149] A rack system 10 is mainly provided in the interior I4 of the warehouse 4000. The rack system 10 is similar to any one of the rack systems 10 in the first embodiment, the embodiment of the modified example 1A, and the embodiment of the modified example 1B, except that the racks store products G instead of cultivating plants P. The products G include products packaged in cardboard boxes or the like.

[0150] The warehouse 4000 mainly has a front wall 11, a left side wall 12, a right side wall 13, a rear wall 14, a ceiling 15, and one or more lights (not shown). The structures and functions of the components of the warehouse 4000 are similar to those of the first embodiment, and therefore will not be described.

[0151] The first work is a warehouse work performed by a person or a device (robot, vehicle, etc.) on the goods G. Examples of the warehouse work include a loading work of loading the goods G onto a rack, a picking work of picking the goods G from the rack, a confirmation work of confirming the quantity and condition of the goods G, and other warehouse work. A roller conveyor (not shown) for transporting the goods G may be provided inside the warehouse 4000.

[0152] (5-5-2) Features The rack system 10 includes three or more racks in which products G are stored. The racks are present inside another structure and are approximately parallel to a first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move approximately perpendicularly to the first vertical wall. Even when the movable rack is moved approximately perpendicularly to the first vertical wall, at least one of the three or more racks is a first rack that is a rack in which an aisle A that is approximately parallel to the first vertical wall is not secured, which is an aisle A used by a person or a device when a first task, which is a task performed by a person or a device on a product G, is performed. By moving the movable rack approximately perpendicularly to the first vertical wall, one or more of the three or more racks are changed to a second rack that is a rack in which an aisle A is secured.

[0153] Racks are used inside the structure to store goods. Storing goods requires human or machine work on the goods. Inside the structure, aisles are provided for use by human or machine work. As a result, a large amount of space is taken up by the aisles inside the structure, reducing the space available for storing goods. This increases the space cost for storing goods. Also, air conditioning may be performed inside the structure to create an environment suitable for storing goods inside the structure. The amount of energy required for air conditioning is correlated with the volume. Wide aisles inside the structure increase the amount of energy required for storing goods. This increases the air conditioning cost for storing goods.

[0154] The rack system 10 can achieve space-saving and energy-saving in storing the products G. Furthermore, the rack system 10 can ensure the aisle A for the first rack as well, making it possible to perform the first work on the products G.

[0198] (2-2) Control device 44 is a functional block diagram of the control device 29. The control device 29 mainly includes a reception unit 291 and a movement control unit 292.

[0199] (2-2-1) Reception The reception unit 291 receives work information and completion information from a person or device via an input device (not shown). The reception unit 291 also receives purchase orders. A purchase order is information indicating the location of a plant P to be purchased. For example, the reception unit 291 receives a purchase order from a terminal. Examples of terminals include, but are not limited to, mobile terminals (smartphones, mobile terminals, tablet terminals, notebook computers, wearable terminals, etc.), desktop personal computers, touch panels, and POS (Point of Sales) terminals.

[0200] The receiving unit 291 may receive at least one of the work information, the completion information, and the purchase order from a server or the cloud via a network.

[0201] (2-2-2) Movement control unit The movement control unit 292 controls, based on the work information, so that racks 200B and 200C are moved in a direction approximately perpendicular to the front wall 11.

[0204] 25 and 28 to 33 have already been realized, the movement control unit 292 does not move the racks 200B and 200C. The racks 200C and 200D remain as the first racks. The rack 200A remains as the second rack.

[0205] 34 to 38, the movement control unit 292 moves the rack 200B substantially in the X direction. As a result, the rack 100A, which is the first rack, changes to the second rack. The rack 200D remains the first rack.

[0206] 39 to 43, the movement control unit 292 moves the rack 200B and the rack 200C substantially in the X direction. As a result, the rack 200A, which is the first rack, changes to the second rack. The rack 200D, which is the second rack, changes to the first rack.

[0207] When work information is received indicating that the target of the first work is the front side of rack 200B or the rear side of rack 200C, the movement control unit 292 controls rack 200B and rack 200C so that the configurations of rack system 20 in Figures 34 to 38 are realized.

[0208] 25 and 28 to 33, the movement control unit 292 moves the rack 200B in approximately the negative X direction. As a result, the rack 200A, which is the second rack, becomes the first rack. The rack 200D remains the first rack.

[0209] 34 to 38 have already been realized, the movement control unit 292 does not move the racks 200B and 200C. The racks 200A and 200D remain as the first racks.

[0210] 39 to 43, the movement control unit 292 moves the rack 200C substantially in the X direction. As a result, the rack 200D, which is the second rack, becomes the first rack. The rack 200A remains the first rack.

[0211] When work information is received indicating that the target of the first work is the front side of rack 200C or rack 200D, the movement control unit 292 controls rack 200B and rack 200C so that the aspects of the rack system 20 in Figures 39 to 43 are realized.

[0212] 25 and 28 to 33, the movement control unit 292 moves the rack 200B and the rack 200C in the approximately negative X direction. The first rack, ie, the rack 200D, changes to the second rack. The second rack, ie, the rack 200A, changes to the first rack.

[0213] 34 to 38, the movement control unit 292 moves the rack 200C in approximately the negative X direction. The first rack, ie, the rack 200D, becomes the second rack. The rack 200A remains the first rack.

[0214] 39 to 43 have already been realized, the movement control unit 292 does not move the racks 200B and 200C. The racks 200A and 200B remain the first racks. The rack 200D remains the second rack.

[0215] In rack system 20, the first rack is always present no matter where the movable racks (rack 200B, rack 200C) are moved. Note that the configuration of rack system 20 is not limited to the configurations of rack system 20 in Fig. 25 and Fig. 28 to Fig. 43. Various configurations can be realized by the movable rack being guided and slid by first guide rails 171C and 171D and second guide rails 172A and 172B.

[0216] (2-2-2-2) Control based on termination information When the completion information is accepted, the movement control unit 292 moves the racks 200B and 200C in a direction substantially perpendicular to the front wall 11 so that the state of the rack system 20 in Fig. 25 and Fig. 28 to Fig. 33 is realized. In other words, after the first work is completed, the movement control unit 292 moves the racks 200B and 200C in a direction substantially perpendicular to the front wall 11 so that the state of the rack system 20 in Fig. 25 and Fig. 28 to Fig. 33 is realized. As a result, the racks 200A, 200B, 200C, and 200D no longer face the opening O.

[0217] 25 and 28 to 33 have already been realized, the movement control unit 292 does not move racks 200B and 200C. In the case of the rack system 20 in the states of FIGS. 34 to 38, the movement control unit 292 moves rack 200B approximately in the X direction. In the case of the rack system 20 in the states of FIGS. 39 to 43, the movement control unit 292 moves racks 200B and 200C approximately in the X direction.

[0218] (2-2-2-3) Control based on purchase orders When a purchase order is received indicating that the location of the plant P to be purchased is behind rack 200A or rack 200B, the movement control unit 292 controls rack 200B and rack 200C so that the aspects of the rack system 20 in Figures 25 and 28 to 33 are realized.

[0219] When a purchase order is received indicating that the location of the plant P to be purchased is in front of rack 200B or behind rack 200C, the movement control unit 292 controls rack 200B and rack 200C so that the aspects of the rack system 20 in Figures 34 to 38 are realized.

[0220] When a purchase order is received indicating that the location of the plant P to be purchased is in front of rack 200C or rack 200D, the movement control unit 292 controls rack 200B and rack 200C so that the aspects of the rack system 20 in Figures 39 to 43 are realized.

[0221] (3) Operation The operation of the facility 2 will be described when a person or device performs the first task and when a purchase order is accepted. In the following operations, the rack system 20 is in the form shown in FIG. 25 and FIG. 28 to FIG. 33. Heated air is supplied to the interior I1 from the opening O. Therefore, the interior I1 maintains a higher temperature than the outside of the plant factory 1000. The interior I1 has an environment suitable for cultivating a plant P.

[0222] (3-1) When a person or equipment performs the first operation 45 is a flowchart showing the operation of the facility 2 when a person or device performs a first task. The first task is performed in the order of rack 200A, the rear side of rack 200B, the front side of rack 200B, the rear side of rack 200C, the front side of rack 200C, and rack 200D.

[0223] Aisle A for rack 200A has already been secured. A person or device moves to the front of rack 200A through entrance / exit 121 and aisle A. The person or device starts a first task on rack 200A. After the first task on rack 200A is completed, the person or device starts a first task on the rear side of rack 200B, since aisle A on the rear side of rack 200B has already been secured. After the first task on the rear side of rack 200B is completed, the person or device leaves aisle A.

[0224] A person or device inputs work information indicating that the target of the first work is the front side of rack 200B to control device 29. Receiving unit 291 receives the work information indicating that the target of the first work is the front side of rack 200B. Movement control unit 292 moves rack 200B in approximately the negative X direction (step S11). In this way, movement control unit 292 realizes the aspects of rack system 20 in FIGS. 34 to 38.

[0225] The person or device moves to the front of rack 200B via aisle A. The person or device starts a first task on the front side of rack 200B. After the first task on the front side of rack 200B is completed, the person or device starts a first task on the rear side of rack 200C because aisle A on the rear side of rack 200C has already been secured. After the first task on the rear side of rack 200C is completed, the person or device leaves aisle A.

[0226] A person or device inputs work information indicating that the target of the first work is the front side of rack 200C to control device 29. Receiving unit 291 receives the work information indicating that the target of the first work is the front side of rack 200C. Movement control unit 292 moves rack 200C in approximately the negative X direction (step S12). In this way, movement control unit 292 realizes the aspects of rack system 20 in Figs. 39 to 43.

[0227] A person or device moves to the front of rack 200C via aisle A. The person or device starts a first task on the front side of rack 200C. After the first task on the front side of rack 200C is completed, the person or device starts the first task on rack 200D because aisle A for rack 200D has already been secured. After the first task on rack 200D is completed, the person or device leaves aisle A.

[0228] A person or device inputs end information to the control device 29. The receiving unit 291 receives the end information. The movement control unit 292 moves rack 200B and rack 200C substantially in the X direction (step S13). As a result, the movement control unit 292 realizes the state of the rack system 20 in FIG. 25 and FIG. 28 to FIG. 33. The opening O no longer faces the four racks (rack 200A, rack 200B, rack 200C, rack 200D).

[0229] (3-2) When a purchase order is accepted Fig. 46 is a flowchart showing the operation of the equipment 2 when a purchase order is accepted. A user who wants to purchase a plant P inputs a purchase order for the plant P to a terminal. The purchase order indicates that the position of the plant P to be purchased is the front side of the rack 200C. The purchase order is transmitted from the terminal to the control device 29. The accepting unit 291 accepts the purchase order (step S21).

[0230] The movement control unit 292 moves the rack 200B and the rack 200C substantially in the negative X direction so as to realize the states of the rack system 20 in FIGS. 39 to 43 (step S22).

[0231] The person or equipment moves to the front of rack 200C through entrance / exit 121 and aisle A. The person or equipment starts harvesting work on the plants P related to the purchase order. The person or equipment harvests the plants P related to the purchase order. After the harvesting work on the plants P related to the purchase order is completed, the person or equipment leaves aisle A.

[0232] A person or device inputs the end information to the control device 29. The reception unit 291 receives the end information. The movement control unit 292 moves the rack 200B and the rack 200C substantially in the X direction (step S23) so that the state of the rack system 20 in FIG. 25 and FIG. 28 to FIG. 33 is realized. The opening O no longer faces the four racks (rack 200A, rack 200B, rack 200C, rack 200D).

[0233] (4) Features (4-1) The rack system 20 further includes a second guide rail 172A and a second guide rail 172B that are fixed to the ceiling 15 of the other structure and extend in a direction substantially perpendicular to the first vertical wall. The movable rack is guided and slid by the first guide rail 171C and the first guide rail 171D and the second guide rail 172A and the second guide rail 172B, and thereby moved in a direction substantially perpendicular to the first vertical wall.

[0234] To utilize the space in the vertical direction (Y direction), a tall movable rack is used. A tall movable rack may be structurally unstable when moved. The rack system 20 also uses second guide rails 172A and 172B fixed to the ceiling 15 to move the movable rack. The rack system 20 makes it easy to utilize the space in the vertical direction, and can achieve space and energy savings in cultivating the plant P.

[0235] (4-2) In the rack system 20, at least one of the movable racks is a third rack, which requires an aisle A from both the first vertical wall side and the second vertical wall side of another structure opposite the first vertical wall.

[0236] When a movable rack moves in the forward direction of the movable rack, the passage in front of the movable rack disappears and an passage behind the movable rack is secured. The state of the space on both the front side of the movable rack and the rear side of the movable rack changes. Therefore, when an passage is secured from one side of the movable rack (for example, the front side of the movable rack), if the movable rack is moved, the passage of the movable rack may be secured again from the other side (for example, the rear side of the movable rack). This passage may become useless.

[0237] In the rack system 20, the racks 200B and 200C are third racks that require the passages A from both sides of the front wall 11 and the rear wall 14. Therefore, the rack system 20 can efficiently move the movable racks, and can further reduce the energy required for the plants P.

[0238] (4-3) In the rack system 20, a rack located at the shortest distance from the first vertical wall in a direction substantially perpendicular to the first vertical wall is not the third rack. A rack located at the shortest distance from the second vertical wall in a direction substantially perpendicular to the second vertical wall is not the third rack.

[0239] If the rack closest to the vertical wall is the third rack, an aisle is required between the vertical wall and the rack. However, since the vertical wall does not require an aisle, one side of the aisle is wasted.

[0240] In the rack system 20, the rack 200D that is the shortest distance from the front wall 11 and the rack 200A that is the shortest distance from the rear wall 14 are not the third rack. Therefore, the rack system 20 can ensure that the aisle A can function as an aisle on both sides. Also, the rack system 20 can limit the movable racks to a portion, and can shorten the movable distance of the movable racks. Therefore, the rack system 20 can further achieve energy savings.

[0241] (4-4) The control device 29 further includes a reception unit 291 that receives a purchase order for the plant P cultivated in the three or more racks. When the reception unit 291 receives a purchase order, the movement control unit 292 further controls the movable rack to be moved in a direction substantially perpendicular to the first vertical wall to secure an aisle A for the purchase order among the three or more racks.

[0242] In some cases, a purchase order for a plant to be grown on the racks requires an immediate response. If a person were to check the contents of the purchase order and control the movable racks based on the contents of the purchase order, the control would take time and effort.

[0243] When a purchase order is accepted, the control device 29 controls so as to secure passage A for the purchase order. Therefore, the control device 29 can shorten the work time and effort required for the purchase order.

[0244] (5) Variations Regarding the modified example of the second embodiment, the description will be omitted for the similarities to the second embodiment, and the description will be centered on the differences from the second embodiment.

The mushrooms M may be cultivated in a mushroom bed bag instead of the mycelium bottles B. The mushrooms M may be cultivated on wood instead of the mycelium bottles B.

[0253] The first operation is a mushroom picking operation by a person or a machine on the mushrooms M. The passage A is used by the person or the machine when the mushroom picking operation is performed. The purchase order is information indicating the location of the mushrooms M to be purchased.

[0254] (5-4-2) Features The control device 29 further includes a reception unit 291 that receives a purchase order for the mushrooms M cultivated in the three or more racks. When the reception unit 291 receives a purchase order, the movement control unit 292 further controls the movable rack to be moved in a direction substantially perpendicular to the first vertical wall to secure an aisle A for the purchase order among the three or more racks.

[0255] There are cases where an immediate response is required for purchase orders for mushrooms grown on racks. The control device 29 can shorten the work time and reduce the effort required for purchase orders.

[0256] (5-5) Variation 2E (5-5-1) Structure The facility 2 may include a warehouse 4000 instead of the plant factory 1000. A rack system 20 is mainly provided in the interior I4 of the warehouse 4000. The rack system 20 is similar to the rack system 20 in any one of the second embodiment, the embodiment of the modified example 2A, and the embodiment of the modified example 2B, except that instead of cultivating plants P on the racks, products G are stored therein. The products G include products packaged in cardboard boxes or the like.

[0257] The warehouse 4000 mainly has a front wall 11, a left side wall 12, a right side wall 13, a rear wall 14, a ceiling 15, and one or more lights (not shown). The structures and functions of the components of the warehouse 4000 are similar to those of the second embodiment, and therefore will not be described.

[0258] The first task is a warehouse task performed by a person or a device (robot, vehicle, etc.) on the product G. The aisle A is used by the person or the device when the warehouse task is performed. The purchase order is information indicating the location of the product G to be purchased.

[0259] (5-5-2) Features The control device 29 further includes a reception unit 291 that receives a purchase order for the product G stored in the three or more racks. When the reception unit 291 receives a purchase order, the movement control unit 292 further controls the movable rack to be moved in a direction substantially perpendicular to the first vertical wall to secure an aisle A for the purchase order among the three or more racks.

[0260] There are cases where an immediate response is required to purchase orders for products stored in the racks. The control device 29 can shorten the work time and reduce the effort required for purchasing orders.

[0261] <Third embodiment> (1) Overall structure The overall configuration of the facility 3 according to the third embodiment will be described.

The configuration of the plant factory 1000 is similar to that of the first embodiment except for the openings O1 and O2, so a description thereof will be omitted.

[0263] An opening O1 and an opening O2 are provided in the left side wall 12. The openings O1 and O2 are openings for supplying conditioned air from an air conditioner (not shown) to the interior I1.

[0264] The openings O1 and O2 may be provided in at least one of the front wall 11, the left side wall 12, the right side wall 13, and the rear wall 14. The openings O1 and O2 do not have to be provided. The openings O1 and O2 may be formed not only by holes provided in the components of the plant factory 1000, but also by holes provided in an air conditioner present in the interior I1. In other words, the openings O1 and O2 may be air outlets of an air conditioner present in the interior I1. The number of openings is not limited to two (openings O1 and O2). The number of openings may be three or more.

[0265] (1-2) Sensor The sensor Y1 and the sensor Y2 detect the presence of a person or a device in the passage A and generate detection information. Examples of the sensor Y1 and the sensor Y2 include, but are not limited to, an infrared sensor, an image sensor, a heat sensor, and an electromagnetic sensor.

The control device 39 may be connected to the rack systems 30 provided in multiple plant factories 1000.

[0268] (2) Detailed configuration (2-1) Rack system A detailed configuration of the rack system 30 will be described. The rack system 30 mainly includes a rack 300A, a rack 300B, a rack 300C, and a rack 300D. The number of racks included in the rack system 30 may be three or more, and is not limited to four.

[0269] The structure of rack 300A and the structure of rack 300D are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The structure of rack 300B and the structure of rack 300C are similar. The function of rack 300A and the function of rack 300D are similar. The function of rack 300B and the function of rack 300C are similar. The structure and function of rack 300A and the structure and function of rack 300B are described below.

[0270] (2-1-1) Rack 300A 48 is a perspective view showing a detailed configuration of the rack 300A. The rack 300A has a plurality of stands S arranged substantially perpendicular to the floor F. For example, the rack 300A has six stands S arranged substantially perpendicular to the floor F. A plant P is grown on each stand S.

The rack 300B may be provided with a lighting device (not shown) that serves as a light source for the plant P.

[0272] Furthermore, rack 300B is provided with first wheels 181A, 181B, 181C, 181D, 182A, 182B, 182C, and 182D.

[0273] The first wheel 181A, the first wheel 181B, the first wheel 181C, and the first wheel 181D are wheels that come into contact with the floor F. The rotation axes (not shown) of the first wheel 181A, the first wheel 181B, the first wheel 181C, and the first wheel 181D are approximately parallel to the front wall 11.

[0274] The second wheel 182A, the second wheel 182B, the second wheel 182C, and the second wheel 182D are wheels that come into contact with the ceiling 15. The rotation axes (not shown) of the second wheel 182A, the second wheel 182B, the second wheel 182C, and the second wheel 182D are approximately parallel to the front wall 11.

[0275] By rotating first wheel 181A, first wheel 181B, first wheel 181C, first wheel 181D, second wheel 182A, second wheel 182B, second wheel 182C, and second wheel 182D, rack 300B is moved in a direction approximately perpendicular to front wall 11. Rack 300B is a movable rack.

[0276] The number of wheels (first wheel 181A, first wheel 181B, first wheel 181C, first wheel 181D, second wheel 182A, second wheel 182B, second wheel 182C, second wheel 182D) attached to rack 300B is not limited to the above example.

[0277] (2-1-3) Various aspects of rack systems Various aspects of the rack system 30 will be described. Fig. 50 is a front view showing the detailed configuration of the rack system 30. Fig. 51 is a rear view showing the detailed configuration of the rack system 30. Fig. 52 is a left side view showing the detailed configuration of the rack system 30. Fig. 53 is a right side view showing the detailed configuration of the rack system 30. Fig. 54 is a plan view showing the detailed configuration of the rack system 30. Fig. 55 is a schematic configuration diagram showing the configuration of the facility 3 excluding four racks (rack 300A, rack 300B, rack 300C, rack 300D).

[0278] The rack 300A is approximately parallel to the front wall 11 and the rear wall 14. The rack 300A is a rack that is located at the shortest distance in a substantially vertical direction to the rear wall 14. The rack 300A is long in the approximately horizontal direction in which the front wall 11 extends, due to the racks 300B and 300C.

[0279] The rack 300A is provided so that the shortest distance from the left side wall 12 to the rack 300A is a value between 0 cm and 5 cm, but is not limited to this. The rack 300A is provided so that the shortest distance from the right side wall 13 to the rack 300A is a value between 0 cm and 5 cm, but is not limited to this. The rack 300A is provided so that the shortest distance from the rear wall 14 to the rack 300A is a value between 0 cm and 5 cm, but is not limited to this.

[0280] There is a space in front of the rack 300A, but the space is not secured to the depth of the aisle A. Therefore, the aisle A does not exist in front of the rack 300A. The rack 100A is the first rack.

[0281] The rack 300B is approximately parallel to the front wall 11 and the rear wall 14. The movement direction of the rack 300B is approximately perpendicular to the front wall 11. Therefore, even when the rack 300B is moved, it remains approximately parallel to the front wall 11 and the rear wall 14. The rack 300B is short in the approximately horizontal direction in which the front wall 11 extends, due to the racks 300A and 300D.

[0303] (2-2) Control device A detailed configuration of the control device 39 will be described below. Fig. 66 is a functional block diagram of the control device 39. The control device 39 mainly includes a receiving unit 390, a receiving unit 391, a movement control unit 392, and a storage unit 393.

[0304] (2-2-1) Receiving section The receiving unit 390 receives the detection information from the sensor Y1 and the sensor Y2.

[0305] (2-2-2) Reception The reception unit 391 receives work information, start information, and end information from a person or device via an input device (not shown). The start information is information indicating the start time when the first task is to be started and the target rack for the first task. The reception unit 391 records the received start information in the storage unit 393.

[0306] The receiving unit 391 may receive at least one of the task information, end information, and start information from a server or cloud via a network. The start information may include information associating at least one of the date, month, date, day, and day of the week with the start time.

[0307] (2-2-3) Movement control unit The movement control unit 392 controls the racks 300B and 300C to be moved in a direction substantially perpendicular to the front wall 11 based on the work information. The movement control unit 392 controls the racks 300B and 300C to be moved in a direction substantially perpendicular to the front wall 11 before the start time to ensure passage A for the racks that are the targets of the first work. The movement control unit 392 controls the racks 300B and 300C to be moved in a direction substantially perpendicular to the front wall 11 based on the end information so that the racks 300A, 300B, 300C, and 300D do not face the openings O1 and O2. When the receiving unit 390 receives the detection information, the movement control unit 392 controls the racks 300B and 300C not to be moved in a direction substantially perpendicular to the front wall 11.

[0308] The control of the movement control unit 392 will be explained below by dividing it into control based on work information, control based on start information, control based on end information, and control based on detection information.

[0309] (2-2-3-1) Control based on work information When work information indicating that the target of the first work is rack 300A or 300B is received, the movement control unit 392 controls rack 300B and rack 300C so that the aspects of the rack system 30 in Figures 56 to 60 are realized.

[0310] In the case of the rack system 30 in the modes of Figures 47 and 50 to 55, the movement control unit 392 moves the racks 300B and 300C substantially in the X direction. As a result, the racks 300A and 300B, which are the first racks, become the second racks. The racks 300C and 300D remain the first racks.

[0311] 56 to 60 have already been realized, the movement control unit 392 does not move the racks 300B and 300C. The racks 300C and 300D remain as the first racks. The racks 300A and 300B remain as the second racks.

[0312] 61 to 65, the movement control unit 392 moves the racks 300B and 300C substantially in the X direction. As a result, the first racks, ie, the racks 300A and 300B, become the second racks. The second racks, ie, the racks 300C and 300D, become the first racks.

[0313] When work information indicating that the target of the first work is rack 300C or 300D is received, the movement control unit 392 controls rack 300B and rack 300C so that the aspects of the rack system 30 in Figures 61 to 65 are realized.

[0314] In the case of the rack system 30 in the modes of Figures 47 and 50 to 55, the movement control unit 392 moves racks 300B and 300C in approximately the negative X direction. As a result, racks 300C and 300D, which are the first racks, become second racks. Racks 300A and 300B remain the first racks.

[0315] In the case of the rack system 30 in the embodiment of Figures 56 to 60, the movement control unit 392 moves the racks 300B and 300C in the approximately negative X direction. As a result, the first racks, that is, the racks 300C and 300D, become the second racks. The second racks, that is, the racks 300A and 300B, become the first racks.

[0316] 61 to 65 have already been realized, the movement control unit 392 does not move the racks 300B and 300C. The racks 300A and 300B remain as the first racks. The racks 300C and 300D remain as the second racks.

[0317] In the rack system 30, the first rack always exists no matter where the movable racks (rack 300B, rack 300C) are moved. The state of the rack system 30 is not limited to the state of the rack system 30 in Fig. 47 and Fig. 50 to Fig. 65. The first wheel 181A, the first wheel 181B, the first wheel 181C, the first wheel 181D, the second wheel 182A, the second wheel 182B, the second wheel 182C, and the second wheel 182D are rotated, whereby the movable rack is moved and various states can be realized.

[0318] (2-2-3-2) Control based on start information The movement control unit 392 reads start information from the memory unit 393. The movement control unit 392 specifies the start time and the target rack for the first work based on the start information. The movement control unit 392 controls the rack 300B and the rack 300C to be moved in a direction substantially perpendicular to the front wall 11 before the start time to ensure the aisle A for the target rack for the first work. An example of a time before the start time includes, but is not limited to, a time between 30 seconds and 5 minutes after the start time.

[0319] When the target of the first work in the start information is rack 300A or rack 300B, the movement control unit 392 controls rack 300B and rack 300C so that the state of the rack system 30 in Figures 56 to 60 is realized by the start time. When the target of the first work in the start information is rack 300C or rack 300D, the movement control unit 392 controls rack 300B and rack 300C so that the state of the rack system 30 in Figures 61 to 65 is realized by the start time.

[0320] (2-2-3-3) Control based on termination information When the completion information is received, the movement control unit 392 moves the racks 300B and 300C in a direction substantially perpendicular to the front wall 11 so that the state of the rack system 30 in Fig. 47 and Fig. 50 to Fig. 55 is realized. In other words, the movement control unit 392 moves the racks 300B and 300C in a direction substantially perpendicular to the front wall 11 so that the state of the rack system 30 in Fig. 47 and Fig. 50 to Fig. 55 is realized after the first work is completed. The racks 300A, 300B, 300C, and 300D no longer face the openings O1 and O2.

[0321] 47 and 50 to 55 have already been realized, the movement control unit 392 does not move racks 300B and 300C. In the case of the rack system 30 in the states of FIGS. 56 to 60, the movement control unit 392 moves racks 300B and 300C substantially in the negative X direction. In the case of the rack system 30 in the states of FIGS. 61 to 65, the movement control unit 392 moves racks 300B and 300C substantially in the X direction.

[0322] (2-2-3-4) Control based on detection information When the receiving unit 390 receives the detection information, the movement control unit 392 controls so that the racks 300B and 300C do not move. The control based on the detection information is given priority over other controls. In other words, the control based on the detection information is given priority over the control based on the work information, the control based on the start information, and the control based on the end information. Therefore, when a person or device is present in the aisle A, the movement control unit 392 does not perform the control based on the work information, the control based on the start information, and the control based on the end information, and controls so that the racks 300B and 300C do not move.

[0323] (2-2-4) Storage section The start information is stored in the storage unit 393. Examples of the storage unit 393 include a hard disk drive (HDD) and a solid state drive (SSD).

[0324] (3) Operation The operation of the equipment 3 when a person or device performs a first task will be described. Start information is pre-recorded in the memory unit 393. The start information indicates that the start time is 8 o'clock and that the target of the first task is rack 300A. The first task is performed on rack 300A, rack 300B, rack 300C, and rack 300D in that order. FIG. 67 is a flowchart showing the operation of the equipment 3. The configuration of the rack system 30 is the configuration of the rack system 30 in FIG. 47 and FIG. 50 to FIG. 55.

[0325] Heated air is supplied to the interior I1 through the openings O1 and O2. Therefore, the interior I1 maintains a higher temperature than the outside of the plant factory 1000. The interior I1 has an environment suitable for cultivating the plant P.

[0326] The movement control unit 392 reads the start information from the storage unit 393. The movement control unit 392 specifies that the start time is 8 o'clock and that the target of the first task is rack 300A.

[0327] At 7:57, which is three minutes before the start time, the movement control unit 392 moves rack 300B and rack 300C substantially in the X direction (step S31). In this way, the movement control unit 392 realizes the state of the rack system 30 shown in Fig. 56 to Fig. 60. Note that step S31 may be performed at any time that allows aisle A for the rack that is the target of the first task to be secured by the start time, and is not limited to a time three minutes before the start time.

[0328] At the start time (8:00), aisle A for rack 300A has already been reserved, so the person or device can move to the front of rack 300A via aisle A. The person or device starts a first task on rack 300A. After the first task on rack 300A is completed, aisle A for rack 300B has also been reserved, so the person or device starts a first task on rack 300B. After the first task on rack 300B is completed, the person or device leaves aisle A.

[0329] A person or device inputs work information indicating that the target of the first work is rack 300C to the control device 39. The reception unit 391 receives the work information indicating that the target of the first work is rack 300C. The movement control unit 392 moves rack 300B and rack 300C in approximately the negative X direction (step S32).

[0330] A person or device moves to the front of rack 300C via aisle A. The person or device starts a first task on rack 300C. After the first task on rack 300C is completed, because aisle A for rack 300D is also secured, the person or device starts a first task on rack 300D. After the first task on rack 300D is completed, the person or device leaves aisle A.

[0331] A person or device inputs end information to the control device 39. The receiving unit 391 receives the end information. The movement control unit 392 moves rack 300B and rack 300C substantially in the X direction (step S33). As a result, the movement control unit 392 realizes the state of the rack system 30 in FIG. 47 and FIG. 50 to FIG. 55. The openings O1 and O2 no longer face the four racks (rack 300A, rack 300B, rack 300C, and rack 300D).

[0332] (4) Features (4-1) In the rack system 30, the movable rack is provided with first wheels 181A, 181B, 181C, and 181D that come into contact with the floor F of another structure. The movable rack is moved in a direction approximately perpendicular to the first vertical wall by rotating first wheels 181A, 181B, 181C, and 181D.

[0333] In order for the movable rack to move on the guide rails, the guide rails must be provided in advance. The movable rack of the rack system 30 is moved by rotating the first wheels 181A, 181B, 181C, and 181D. The rack system 30 can move the movable rack without providing the guide rails in advance.

[0334] (4-2) In the rack system 30, the rotation axes of the first wheels 181A, 181B, 181C, and 181D are substantially parallel to the first vertical wall.

[0335] The first wheels 181A, 181B, 181C, and 181D rotate about a rotation axis that is approximately parallel to the front wall 11. The movable rack is moved in a direction approximately perpendicular to the front wall 11. Therefore, the force received by the movable rack is not dispersed, and the movable rack is moved efficiently in a direction approximately perpendicular to the front wall 11. This makes it easier for the rack system 30 to ensure the passage A for the rack.

[0336] (4-3) In the rack system 30, the movable rack is further provided with second wheels 182A, 182B, 182C, and 182D that come into contact with the ceiling 15 of another structure. The movable rack is moved in a direction approximately perpendicular to the first vertical wall by rotating the first wheels 181A, 181B, 181C, 181D, 182A, 182B, 182C, and 182D.

[0337] To utilize the vertical space, a tall movable rack is used. A tall movable rack may be structurally unstable when moved. The rack system 30 moves the movable rack using second wheels 182A, 182B, 182C, and 182D that contact the ceiling 15. The rack system 30 makes it easy to utilize the vertical space, and can achieve space and energy savings in cultivating the plant P.

[0338] (4-4) The control device 39 further controls the movement control unit 392 so that, before the start time, which is the time when the first work is to begin, the movable rack is moved in a direction approximately perpendicular to the first vertical wall to secure an aisle A for the rack that is the target of the first work, among the three or more racks.

[0339] It takes time to move the movable rack. Therefore, the first work may be delayed due to the movement of the movable rack. The control device 39 controls to secure aisle A for the rack that is the target of the first work before the start time. This allows the control device 39 to reduce the time it takes to move the movable rack, and to make the first work more efficient.

[0340] (4-5) The control device 39 further includes a receiving unit 390 that receives detection information indicating the presence of a person or device in the aisle A from the sensors Y1 and Y2 that detect the presence of a person or device in the aisle A. When the movement control unit 392 receives the detection information, it further controls the movable rack so that it is not moved in a direction approximately perpendicular to the first vertical wall.

[0341] If the movable rack is moved when there is a person or device in the passage, the person may be injured or the device may be damaged. When the control device 39 receives the detection information, it controls the movable rack so that it is not moved. Therefore, the control device 39 can ensure the safety of the person or device.

[0342] (4-6) The control device 39 determines that the other structure has a plurality of openings (opening O1 and opening O2). The movement control unit 392 further controls the movable rack to be moved in a direction substantially perpendicular to the first vertical wall after the first work is completed so that three or more racks do not face the plurality of openings.

[0343] When the racks are arranged close together, it is difficult for airflow to form, and temperature or humidity unevenness may occur. In the other structure, there are openings O1 and O2. The control device 39 controls the movable rack to be moved so as not to face the openings O1 and O2 after the first work is completed. Therefore, the control device 39 can reduce the possibility of temperature or humidity unevenness occurring by the airflow from the multiple openings, and can make the interior I1 an environment more suitable for growing the plant P.
