Rack 100E is installed such that the shortest distance from the front wall 11 to rack 100E is between 0 cm and 5 cm, but is not limited to this.

[0062] There is no aisle A in front of or behind rack 100E. Rack 100E is the first rack.

[0063] The first guide rails 171A and 171B are fixed to the floor F. Alternatively, the first guide rails 171A and 171B may be fixed to the recessed portion of the concave shape of the floor F. In this case, even if the first guide rails 171A and 171B are present on the floor F, it is less likely that a step will occur in the floor F.

[0064] The first guide rails 171A and 171B extend substantially perpendicular to the front wall 11 and the rear wall 14. The first guide rails 171A and 171B are installed so that the movable racks (rack 100B, rack 100C, rack 100D) are guided and can slide along them.

[0065] The first guide rails 171A and 171B are installed such that the shortest distance from the rear end of the first guide rail 171A and the rear end of the first guide rail 171B to the rack 100A is between 0 cm and 5 cm, but are not limited to this. In other words, the first guide rails 171A and 171B are installed such that the shortest distance from the rack 100B to the rack 100A can be between 0 cm and 5 cm.

[0066] The first guide rails 171A and 171B are installed such that the shortest distance from the front end of the first guide rail 171A and the front end of the first guide rail 171B to the rack 100E is between 0 cm and 5 cm, but are not limited to this. In other words, the first guide rails 171A and 171B are installed such that the shortest distance from the rack 100D to the rack 100E is between 0 cm and 5 cm.

[0067] The depth of the first guide rail 171A and the depth of the first guide rail 171B are the sum of the depth of passage A, the depth of rack 100B, the depth of rack 100C, the depth of rack 100D, and a value between 0 cm and 20 cm, but are not limited to this.

[0068] The shortest distance from rack 100A to rack 100B is greater than or equal to the depth of aisle A. The shortest distance from rack 100B to rack 100C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 100C to rack 100D is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 100D to rack 100E is between 0cm and 5cm, but is not limited to this value.

[0069] In the configurations of the rack system 10 shown in Figures 1 and 4 through 9, passage A faces the opening O. In the configurations of the rack system 10 shown in Figures 1 and 4 through 9, racks 100A, 100B, 100C, 100D, and 100E do not face the opening O.

[0070] Since the shortest distance from racks 100B, 100C, and 100D to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance 121 is also secured.

[0071] This section describes a configuration of rack system 10 that differs from the configurations of rack system 10 shown in Figures 1 and 4 through 9. Figure 10 is a perspective view showing the overall configuration of equipment 1. Figure 11 is a left side view showing the detailed configuration of rack system 10.

[0073] The shortest distance from rack 100A to rack 100B is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 100B to rack 100C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 100C to rack 100D is greater than or equal to the depth of aisle A. The shortest distance from rack 100D to rack 100E is between 0cm and 5cm, but is not limited to this value.

[0074] Aisle A, rack 100A, rack 100C, rack 100D, and rack 100E do not face opening O. Rack 100B faces opening O.

[0075] Since the shortest distance from racks 100B, 100C, and 100D to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance 121 is also secured.

[0076] This section describes configurations of rack system 10 that differ from those shown in Figures 1 and 4 through 9, and those shown in Figures 10 through 14. Figure 15 is a perspective view showing the overall configuration of equipment 1. Figure 16 is a left side view showing the detailed configuration of rack system 10. Figure 17 is a right side view showing the detailed configuration of rack system 10. Figure 18 is a top view showing the detailed configuration of rack system 10. Figure 19 is a schematic configuration diagram showing the configuration of equipment 1 excluding five racks (rack 100A, rack 100B, rack 100C, rack 100D, and rack 100E). The front and rear views showing the detailed configuration of rack system 10 are the same as those in Figures 4 and 5, and are therefore omitted.

[0077] There is no aisle A in front of or behind rack 100A. Rack 100A is the first rack. There is no aisle A in front of or behind rack 100B. Rack 100B is the first rack. There is no aisle A in front of or behind rack 100C. Rack 100C is the first rack. There is an aisle A in front of rack 100D. Rack 100D is the second rack. There is an aisle A behind rack 100E. Rack 100E is the second rack.

[0078] The shortest distance from rack 100A to rack 100B is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 100B to rack 100C is between 0cm and 5cm, but is not limited to this value.

[0079] Aisle A, rack 100A, rack 100C, rack 100D, and rack 100E do not face opening O. Rack 100B faces opening O.

[0080] Since the shortest distance from racks 100B, 100C, and 100D to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance 121 is also secured.

[0081] (2-2) Control device The detailed configuration of the control device 19 will now be described. Figure 20 is a functional block diagram of the control device 19. The control device 19 mainly comprises a reception unit 191 and a movement control unit 192.

[0082] (2-2-1) Reception Department The reception unit 191 receives work information and completion information from a person or device via an input device (not shown). Work information is information indicating the subject of the first work. Completion information is information indicating that the first work has been completed. The reception unit 191 may also receive at least one of the work information and completion information from a server or cloud via a network.

[0083] (2-2-2) Mobile Control Unit The movement control unit 192 controls racks 100B, 100C, and 100D to move approximately perpendicular to the front wall 11 based on work information. Furthermore, the movement control unit 192 controls racks 100A, 100B, 100C, 100D, and 100E to move approximately perpendicular to the front wall 11 based on completion information, so that they do not face the opening O. The control of the movement control unit 192 will be described below, divided into control based on work information and control based on completion information.

[0084] (2-2-2-1) Control based on work information When work information is received indicating that the target of the first work is rack 100A or rack 100B, the movement control unit 192 controls rack 100B, rack 100C, and rack 100D so that the configuration of the rack system 10 shown in Figures 1 and 4 to 9 is realized.

[0085] If the configurations of the rack system 10 shown in Figures 1 and 4 through 9 have already been implemented, the movement control unit 192 will not move racks 100B, 100C, and 100D. Racks 100C, 100D, and 100E will remain as the first rack. Racks 100A and 100B will remain as the second rack.

[0086] In the configuration of the rack system 10 shown in Figures 10 to 14, the movement control unit 192 moves racks 100B and 100C in approximately the X direction. As a result, the first racks, racks 100A and 100B, become the second racks. The second racks, racks 100C and 100D, become the first racks. Rack 100E remains the first rack.

[0087] In the configuration of the rack system 10 shown in Figures 15 to 19, the movement control unit 192 moves racks 100B, 100C, and 100D in approximately the X direction. As a result, the first racks, racks 100A and 100B, become the second racks. The second racks, racks 100D and 100E, become the first racks. Rack 100C remains the first rack.

[0088] When work information is received indicating that the target of the first work is rack 100C, the movement control unit 192 controls rack 100B, rack 100C, and rack 100D so that the configurations of the rack system 10 shown in Figures 10 to 14 are realized.

[0089] In the configuration of the rack system 10 shown in Figures 1 and 4 through 9, the movement control unit 192 moves racks 100B and 100C in approximately the negative X direction. As a result, the first racks, racks 100C and 100D, become the second racks. The second racks, racks 100A and 100B, become the first racks. Rack 100E remains the first rack and does not change.

[0090] If the configurations of the rack system 10 shown in Figures 10 to 14 have already been implemented, the movement control unit 192 will not move racks 100B, 100C, and 100D. Racks 100A, 100B, and 100E will remain as the first rack. Racks 100C and 100D will remain as the second rack.

[0091] In the configuration of the rack system 10 shown in Figures 15 to 19, the movement control unit 192 moves rack 100D in approximately the X direction. As a result, rack 100C, which is the first rack, becomes the second rack. Rack 100E, which is the second rack, becomes the first rack. Rack 100D remains the second rack. Racks 100A and 100B remain the first racks.

[0092] When work information is received indicating that the target of the first work is rack 100D, the movement control unit 192 controls rack 100B, rack 100C, and rack 100D so that the configurations of the rack system 10 shown in Figures 10 to 14 or Figures 15 to 19 are realized.

[0093] In the configuration of the rack system 10 shown in Figures 1 and 4 through 9, the movement control unit 192 moves racks 100B and 100C in approximately the negative X direction. As a result, the first racks, racks 100C and 100D, become the second racks. The second racks, racks 100A and 100B, become the first racks. Rack 100E remains the first rack and does not change.

[0094] If the configurations of the rack system 10 shown in Figures 10 to 14 have already been implemented, the movement control unit 192 will not move racks 100B, 100C, and 100D. Racks 100A, 100B, and 100E will remain as the first rack. Racks 100C and 100D will remain as the second rack.

[0095] If the configurations of the rack system 10 shown in Figures 15 to 19 have already been implemented, the movement control unit 192 will not move racks 100B, 100C, and 100D. Racks 100A, 100B, and 100C will remain as the first racks. Racks 100D and 100E will remain as the second racks.

[0096] When work information is received indicating that the target of the first work is rack 100E, the movement control unit 192 controls rack 100B, rack 100C, and rack 100D so that the configurations of the rack system 10 shown in Figures 15 to 19 are realized.

[0097] In the configuration of the rack system 10 shown in Figures 1 and 4 through 9, the movement control unit 192 moves racks 100B, 100C, and 100D in approximately the negative X direction. The first racks, racks 100D and 100E, are converted into the second rack. The second racks, racks 100A and 100B, are converted into the first rack. Rack 100C remains the first rack and does not change.

[0098] In the configuration of the rack system 10 shown in Figures 10 to 14, the movement control unit 192 moves rack 100D in approximately the negative X direction. Rack 100E, which is the first rack, becomes the second rack. Rack 100C, which is the second rack, becomes the first rack. Rack 100D remains the second rack. Racks 100A and 100B remain the first rack.

[0099] If the configurations of the rack system 10 shown in Figures 15 to 19 have already been implemented, the movement control unit 192 will not move racks 100B, 100C, and 100D. Racks 100A, 100B, and 100C will remain as the first racks. Racks 100D and 100E will remain as the second racks.

[0100] In the rack system 10, the first rack always exists regardless of where the movable racks (rack 100B, rack 100C, rack 100D) are moved. The configuration of the rack system 10 is not limited to the configurations shown in Figures 1 and 4 through 19. Various configurations can be realized by having the movable racks slide guided by the first guide rails 171A and 171B.

[0101] (2-2-2-2) Control based on termination information When completion information is received, the movement control unit 192 moves racks 100B, 100C, and 100D in a direction substantially perpendicular to the front wall 11 so that the configurations of the rack system 10 shown in Figures 1 and 4 to 9 are realized. In other words, after the first operation is completed, the movement control unit 192 moves racks 100B, 100C, and 100D in a direction substantially perpendicular to the front wall 11 so that the configurations of the rack system 10 shown in Figures 1 and 4 to 9 are realized. As a result, after the first operation is completed, racks 100A, 100B, 100C, 100D, and 100E no longer face the opening O.

[0102] If the configurations of the rack system 10 shown in Figures 1 and 4 through 9 have already been implemented, the movement control unit 192 does not move rack 100B, rack 100C, and rack 100D. If the configurations of the rack system 10 shown in Figures 10 through 14 are implemented, the movement control unit 192 moves rack 100B and rack 100C in approximately the X direction. If the configurations of the rack system 10 shown in Figures 15 through 19 are implemented, the movement control unit 192 moves rack 100B, rack 100C, and rack 100D in approximately the X direction.

[0103] (3) Operation The operation of Equipment 1 when a person or device performs the first operation will be described below. The first operation is performed in the order of rack 100A, rack 100B, rack 100C, rack 100D, and rack 100E. Figure 21 is a flowchart of the operation of Equipment 1. The configurations of the rack system 10 are shown in Figures 1 and 4 through 9.

[0104] Warm air is supplied to the interior I1 through the opening O. As a result, the interior I1 maintains a higher temperature than the exterior of the plant factory 1000. The interior I1 provides an environment suitable for cultivating plants P.

[0105] The passage A for rack 100A is already secured. A person or device moves in front of rack 100A via entrance / exit 121 and passage A. The person or device begins the first operation on rack 100A. After the first operation on rack 100A is completed, since passage A for rack 100B is also already secured, the person or device begins the first operation on rack 100B. After the first operation on rack 100B is completed, the person or device leaves passage A.

[0106] A person or device inputs work information to the control device 19 indicating that the target of the first work is rack 100C. 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 racks 100B and 100C in approximately the negative X direction (step S1). As a result, the movement control unit 192 realizes the configuration of the rack system 10 shown in Figures 10 to 14.

[0107] A person or device moves in front of rack 100C via aisle A. The person or device begins the first operation on rack 100C. After the first operation on rack 100C is completed, since aisle A for rack 100D is also already secured, the person or device begins the first operation on rack 100D. After the first operation on rack 100D is completed, the person or device leaves aisle A.

[0108] A person or device inputs work information to the control device 19 indicating that the target of the first work is rack 100E. 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 rack 100D in approximately the negative X direction (step S2). As a result, the movement control unit 192 realizes the configuration of the rack system 10 shown in Figures 15 to 19.

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

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

[0111] (4) Features (4-1) The rack system 10 comprises three or more racks (rack 100A, rack 100B, rack 100C, rack 100D, rack 100E) on which plants P are cultivated. The racks are located inside I1 of another structure and are substantially parallel to the first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move substantially perpendicular to the first vertical wall. Even when the movable rack is moved substantially perpendicular to the first vertical wall, at least one of the three or more racks is a first rack that does not have a passage A, which is used by a person or device when a first operation, which is work performed on plants P, is carried out, and which is a passage A substantially parallel to the first vertical wall. As the movable rack is moved substantially perpendicular to the first vertical wall, one or more of the three or more first racks change into second racks that have a passage A secured.

[0112] Racks are used inside the structure for cultivating plants. Cultivating plants requires human or mechanical work on the plants. Passages are provided inside the structure for the work of humans or mechanical personnel. As a result, a large amount of space is occupied by these passages inside the structure, reducing the space available for plant cultivation. This increases the cost of space for plant cultivation. In addition, air conditioning is provided inside the structure to create an environment suitable for plant cultivation. The amount of energy required for air conditioning correlates with volume. Wide passages inside the structure increase the amount of energy required for plant cultivation. This increases the cost of air conditioning for plant cultivation.

[0113] In the rack system 10, there are racks where aisle A is not secured regardless of where the movable racks are moved. Because there are racks where aisle A is not secured, the rack system 10 can achieve space savings in aisle A. As a result, the rack system 10 can achieve space savings and energy savings in the cultivation of plants P.

[0114] The rack system 10 changes from the first rack to the second rack when the movable rack is moved. As a result, the rack system 10 can secure a passage A for the first rack as well, enabling the first work on the plant P.

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

[0116] (4-2) In the rack system 10, if the movable rack is moved in a direction substantially perpendicular to the first vertical wall, and one or more of the three or more racks change into second racks, then one or more of the three or more racks change into first racks.

[0117] In rack system 10, when a first rack is converted into a second rack, other second racks are converted into first racks. In rack system 10, there are racks that do not have aisle A. Therefore, rack system 10 can achieve space savings in aisle A. As a result, rack system 10 can achieve space savings and energy savings in the cultivation of plants P.

[0118] (4-3) The rack system 10 further comprises first guide rails 171A and 171B, which are fixed to the floor F of another structure and extend substantially perpendicular to the first vertical wall. The movable rack is moved substantially perpendicular to the first vertical wall by sliding guided by the first guide rails 171A and 171B.

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

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

[0121] Vertical walls do not require a passageway. A passageway serves as a passageway on both sides (both sides in the lateral direction relative to the direction of movement of people or equipment). If a passageway is secured between a rack located at the shortest distance approximately perpendicular to the vertical wall and the vertical wall, one side of the passageway (the side facing the vertical wall) cannot serve as a passageway. Therefore, if the rack located at the shortest distance is moved to secure that passageway, a wasted passageway is created on one side. This wasted passageway on one side is a waste of space and lengthens the movement path for people or equipment during work.

[0122] In the rack system 10, the rack 100E located at the shortest distance approximately vertically from the front wall 11 is not a movable rack. Similarly, the rack 100A located at the shortest distance approximately vertically from the rear wall 14 is also not a movable rack. Therefore, the rack system 10 can secure passage A that can function as a passage on both sides. The rack system 10 can limit the number of movable racks to a portion, thereby shortening the movement 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 the cultivation of plants P.

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

[0124] When a passageway is provided in a space adjacent to a vertical wall, one side of the passageway becomes wasted space. Therefore, it is desirable to utilize the space adjacent to the vertical wall as space for racks.

[0125] The rack system 10 is elongated in a substantially horizontal direction, with racks 100A and 100E extending along with racks 100B, 100C, and 100D, forming a first vertical wall. As a result, the rack system 10 can secure a large space for cultivating plants P inside I1, thereby achieving space and energy savings in plant cultivation.

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

[0127] Heavy or large racks can be difficult to move manually. Furthermore, moving racks is a time-consuming process. The control device 19 moves racks 100B, 100C, and 100D. Therefore, the control device 19 can move heavy or large racks, reducing the effort required for their movement.

[0128] (4-7) The control device 19 determines that other structures have openings O for supplying air-conditioned air. The movement control unit 192 further controls the movable racks to move substantially perpendicular to the first vertical wall so that no more than three racks face the openings O after the first operation is completed.

[0129] Air is blown out from the opening that supplies air-conditioned air. When a rack and an opening face each other, the degree of air conditioning may differ significantly between the area around the rack facing the opening and the area far from the opening. Therefore, it may not be possible to provide a suitable environment for cultivation for plants grown on at least one of the racks, either the one facing the opening or the one far from the opening. In addition, the air blown out from the opening may collide with the rack facing the opening, creating an uneven airflow. As a result, temperature or humidity unevenness may occur inside.

[0130] After the first operation is completed, the control device 19 moves the movable racks so that no more than three racks face the opening O. As a result, the control device 19 can reduce the possibility of temperature or humidity unevenness and create an environment more suitable for plant P cultivation inside I1.

[0131] (4-8) The control method includes a movement control step in which the movable rack in the rack system 10 is controlled to move 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, reducing the effort required for movement.

[0133] (5) Variant Regarding the modified version of the first embodiment, we will omit explanations of points that are the same as those of the first embodiment and focus on explaining the differences from the first embodiment.

[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 following: the direction and distance of movement of the movable racks (rack 100B, rack 100C, rack 100D), and the location of movement. The location of movement may be represented by two-dimensional coordinates in a two-dimensional coordinate system of the X and Z axes, or by three-dimensional coordinates in a three-dimensional coordinate system of the X, Y, and Z axes. The reception unit 191 may also receive movement information from a server or cloud via a network.

[0135] (5-2) Variation 1B Equipment 1 does not necessarily need to be equipped with a control device 19. In this case, the possible rack is moved manually in a direction approximately perpendicular to the front wall 11.

[0136] (5-3) Modification 1C Facility 1 may include a greenhouse 2000 instead of a plant factory 1000. Figure 22 is a perspective view showing the overall configuration of Facility 1 according to Modification 1C. The greenhouse 2000 is a structure in which a frame is assembled and the upper part is covered with vinyl or the like for cultivating plants P. Plants P are cultivated inside the greenhouse 2000.

[0137] Furthermore, facility 1 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the vinyl greenhouse 2000. Also, the vinyl greenhouse 2000 may or may not be a building.

[0138] A rack system 10 is mainly provided inside the greenhouse 2000, I2. The rack system 10 is the same as the rack system 10 of the first embodiment, the embodiment of modification 1A, and the embodiment of modification 1B.

[0139] The greenhouse 2000 mainly consists of 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 structure and function of the components of the greenhouse 2000 are the same as in the first embodiment, except for the shape of the ceiling 15, so a description is omitted.

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

[0141] A rack system 10 is mainly provided inside the mushroom cultivation facility 3000 I3. The rack system 10 is the same as the rack system 10 of the first embodiment, the embodiment of modified example 1A, and the embodiment of modified example 1B, except that mushrooms M are cultivated in the racks instead of plants P.

[0142] The mushroom cultivation facility 3000 mainly consists of 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 structure and function of the components of the mushroom cultivation facility 3000 are the same as in the first embodiment, so a description is omitted.

[0143] Five racks (rack 100A, rack 100B, rack 100C, rack 100D, rack 100E) are each containing mycelium bottle B. Mushroom M is cultivated in mycelium bottle B. Mycelium bottle B and mushroom M together are called set MS. Note that mushroom M may be cultivated in a mushroom substrate bag instead of mycelium bottle B. Note that mushroom M may be cultivated on wood instead of mycelium bottle B.

[0144] The first type of work refers to mushroom cultivation work performed by people or equipment on mushroom M. Examples of mushroom cultivation work include inoculation work, which involves planting mushroom M spawn; cultivation work, which is performed for cultivating mushroom M; harvesting work, which involves harvesting all or part of mushroom M; and other mushroom cultivation work.

[0145] (5-4-2) Characteristics The rack system 10 comprises three or more racks on which mushrooms M are cultivated. The racks are located inside another structure and are substantially parallel to the first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move substantially perpendicular to the first vertical wall. Even when the movable rack is moved substantially perpendicular to the first vertical wall, at least one of the three or more racks is a first rack that does not have a passage A, which is used by a person or device when a first operation, which is work performed on the mushrooms M, is carried out, and which is a passage A substantially parallel to the first vertical wall. As the movable rack is moved substantially perpendicular to the first vertical wall, one or more of the three or more first racks change into second racks that have a passage A secured.

[0146] Inside the structure, racks are used for cultivating mushrooms. Mushroom cultivation requires human or mechanical work on the mushrooms. Passages are provided inside the structure for the work of humans or mechanical personnel. As a result, a large amount of space is occupied by these passages inside the structure, reducing the space available for mushroom cultivation. This increases the cost of space for mushroom cultivation. In addition, air conditioning is provided inside the structure to create an environment suitable for mushroom cultivation. The amount of energy required for air conditioning correlates with volume. Wide passages inside the structure increase the amount of energy required for mushroom cultivation. This increases the cost of air conditioning for mushroom cultivation.

[0147] The rack system 10 enables space and energy savings in the cultivation of mushrooms M. Furthermore, the rack system 10 ensures that aisle A is maintained even in the first rack, allowing for the first stage of work on the mushrooms M.

[0148] (5-5) Modification 1E (5-5-1) Structure Facility 1 may include a warehouse 4000 instead of a plant factory 1000. Figure 24 is a perspective view showing the overall configuration of Facility 1 according to Modification 1E. Examples of warehouse 4000 include, but are not limited to, ambient temperature warehouses, low temperature warehouses, frozen warehouses, and refrigerated warehouses.

[0149] A rack system 10 is mainly installed inside warehouse 4000 I4. The rack system 10 is the same as the rack system 10 of the first embodiment, the embodiment of modification 1A, and the embodiment of modification 1B, except that goods G are stored in the racks instead of plants P being cultivated there. Goods G include goods packaged in cardboard boxes or the like.

[0150] Warehouse 4000 mainly consists of 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 structure and function of the components of warehouse 4000 are the same as in the first embodiment, so a description is omitted.

[0151] The first operation is warehouse work performed on product G by a person or equipment (robot, vehicle, etc.). Examples of warehouse work include loading work, which involves placing product G onto racks; picking work, which involves picking product G from racks; checking work, which involves verifying the quantity and condition of product G; and other warehouse work. A roller conveyor (not shown) for transporting product G may be provided inside warehouse 4000.

[0152] (5-5-2) Features The rack system 10 comprises three or more racks on which goods G are stored. The racks are located inside another structure and are substantially parallel to the first vertical wall of the other structure. At least one of the three or more racks is a movable rack that can move substantially perpendicular to the first vertical wall. Even when the movable rack is moved substantially perpendicular to the first vertical wall, at least one of the three or more racks is a first rack that does not have a passage A, which is used by a person or device when a first operation, which is an operation performed by a person or device on goods G, is secured, and which is a passage A substantially parallel to the first vertical wall. As the movable rack is moved substantially perpendicular to the first vertical wall, one or more of the three or more first racks change into second racks that have a passage A secured.

[0153] Racks are used to store goods inside the structure. Storing goods requires human or mechanical work on the goods. Passageways are provided within the structure for human or mechanical work. Therefore, a large portion of the space is occupied by these passageways, reducing the available space for goods storage. This increases the cost of space for goods storage. Furthermore, air conditioning may be provided inside the structure to create an environment suitable for goods storage. The amount of energy required for air conditioning correlates with volume. Wide passageways within the structure increase the amount of energy required for goods storage. This increases the cost of air conditioning for goods storage.

[0154] The rack system 10 can achieve space and energy savings in the storage of product G. In addition, the rack system 10 can secure aisle A in the first rack as well, enabling the first work on product G.

[0155] <Second Embodiment> (1) Overall structure The overall configuration of the equipment 2 according to the second embodiment will be described below. Hereinafter, similarities between the first and second embodiments will be omitted, and the differences between the first and second embodiments will be the focus of the description. Figure 25 is a perspective view showing the overall configuration of equipment 2. Equipment 2 mainly comprises a plant factory 1000 and a control device 29.

[0156] (1-1) Plant factory A rack system 20 is mainly installed inside the plant factory 1000, I1. Details of the rack system 20 will be described later. The configuration of the plant factory 1000 is the same as in the first embodiment, except for the position of the opening O, so a description will be omitted.

[0157] An opening O is provided in the left wall 12. The opening O may also be provided in at least one of the front wall 11, the left wall 12, the right wall 13, and the rear wall 14. The opening O is not required.

[0158] (1-2) Control device The control device 29 primarily controls the rack system 20. The control device 29 connects to the rack system 20 by wire or wireless connection. Details of the control device 29 will be described later. The control device 29 may be installed on internal I1. The control device 29 may also be installed on a server or in the cloud. The control device 29 may be connected to rack systems 20 installed in multiple plant factories 1000.

[0159] (2) Detailed configuration (2-1) Rack System The detailed configuration of the rack system 20 is described below. The rack system 20 mainly consists of rack 200A, rack 200B, rack 200C, rack 200D, first guide rail 171C, first guide rail 171D, second guide rail 172A, and second guide rail 172B. Note that the number of racks in the rack system 20 may be three or more, but is not limited to four.

[0160] The structure of rack 200A and the structure of rack 200D are approximately symmetric with respect to the planes extending in the Y and Z directions. The structure of rack 200B and the structure of rack 200C are the same. The function of rack 200A and the function of rack 200D are the same. The function of rack 200B and the function of rack 200C are the same. The structure and function of rack 200A and rack 200B will be described below.

[0161] (2-1-1) Rack 200A Figure 26 is a perspective view showing the detailed configuration of rack 200A. Rack 200A has a plurality of platforms S arranged substantially perpendicular to the floor F. For example, rack 200A has six platforms S arranged substantially perpendicular to the floor F. Plants P are cultivated on each platform S. Plants P are planted in soil (not shown) on rack 200A or immersed in nutrient solution (not shown) on rack 200A. Rack 200A may be provided with a lighting device (not shown) that serves as a light source for the plants P. Rack 200A is not a movable rack.

[0162] (2-1-2) Rack 200B Figure 27 is a perspective view showing the detailed configuration of rack 200B. Rack 200B has a plurality of stands S arranged substantially perpendicular to the floor F. For example, rack 200B has six stands S arranged substantially perpendicular to the floor F. Plants P are cultivated on each stand S. Plants P are planted in soil (not shown) on rack 200B or immersed in nutrient solution (not shown) on rack 200B. Rack 200B may be provided with a lighting device (not shown) that serves as a light source for plants P.

[0163] Rack 200B is moved approximately perpendicular to the front wall 11 by sliding guided by the first guide rails 171C and 171D and the second guide rails 172A and 172B. Rack 200B is a movable rack.

[0164] The depth of rack 200B is the value obtained by multiplying the depth from which the first operation can be performed from one side (front wall 11 side or rear wall 14 side) by a number between 1 and 2, but is not limited to this. The depth of rack 200B is longer than the depths of racks 200A and rack 200D. Rack 200B requires passages A on both the front and rear sides of rack 200B. In other words, rack 200B is a rack that requires passages A from both the front wall 11 side and the rear wall 14 side. Rack 200B is the third rack. The third rack is a rack that requires passages A from both the front wall 11 side and the rear wall 14 side.

[0165] (2-1-3) Various forms of rack systems Various configurations of the rack system 20 will be described. Figure 28 is a front view showing the detailed configuration of the rack system 20. Figure 29 is a rear view showing the detailed configuration of the rack system 20. Figure 30 is a left side view showing the detailed configuration of the rack system 20. Figure 31 is a right side view showing the detailed configuration of the rack system 20. Figure 32 is a top view showing the detailed configuration of the rack system 20. Figure 33 is a schematic configuration diagram showing the configuration of equipment 2 excluding four racks (rack 200A, rack 200B, rack 200C, and rack 200D).

[0166] Rack 200A is approximately parallel to the front wall 11 and the rear wall 14. Rack 200A is the rack that is located at the shortest distance in the direction approximately perpendicular to the rear wall 14. Rack 200A is elongated in the direction approximately horizontal to the extension of the front wall 11, due to racks 200B and 200C.

[0167] Rack 200A is installed such that the shortest distance from the left wall 12 to rack 200A is between 0 cm and 5 cm, but is not limited to this. Rack 200A is installed such that the shortest distance from the right wall 13 to rack 200A is between 0 cm and 5 cm, but is not limited to this. Rack 200A is installed such that the shortest distance from the rear wall 14 to rack 200A is between 0 cm and 5 cm, but is not limited to this.

[0168] Aisle A exists in front of rack 200A. Rack 200A is a rack that has a reserved aisle A. Rack 200A is the second rack.

[0169] Rack 200B is approximately parallel to the front wall 11 and the rear wall 14. The direction of movement of rack 200B is approximately perpendicular to the front wall 11. Therefore, even when rack 200B is moved, it remains approximately parallel to the front wall 11 and the rear wall 14. Rack 200B is shorter in the approximately horizontal direction in which the front wall 11 extends due to racks 200A and 200D.

[0170] Rack 200B is installed such that the shortest distance from the left wall 12 to rack 200B is greater than or equal to the depth of passage A, but is not limited to this. Rack 200B is installed such that the shortest distance from the right wall 13 to rack 200B is between 0 cm and 5 cm, but is not limited to this.

[0171] There is no aisle A in front of rack 200B. There is an aisle A behind rack 200B. Rack 200B requires aisles A on both sides, but only aisle A on one side (the side behind 200B) is available.

[0172] Rack 200C is approximately parallel to the front wall 11 and the rear wall 14. The direction of movement of rack 200C is approximately perpendicular to the front wall 11. Therefore, even when rack 200C is moved, it remains approximately parallel to the front wall 11 and the rear wall 14. Rack 200C is shorter in the approximately horizontal direction in which the front wall 11 extends due to racks 200A and 200D.

[0173] Rack 200C is installed such that the shortest distance from the left wall 12 to rack 200C is greater than or equal to the depth of passage A, but is not limited to this. Rack 200C is installed such that the shortest distance from the right wall 13 to rack 200C is between 0 cm and 5 cm, but is not limited to this.

[0174] There is no aisle A in front of or behind rack 200C. Rack 200C is the first rack.

[0175] Rack 200D is approximately parallel to the front wall 11 and the rear wall 14. Rack 200D is the rack that is located at the shortest distance in the direction approximately perpendicular to the front wall 11. Rack 200D is elongated in the direction approximately horizontal to the front wall 11, due to the presence of racks 200B and 200C.

[0176] Rack 200D is installed such that the shortest distance from the left wall 12 to rack 200D is between 0 cm and 5 cm, but is not limited to this. Rack 200D is installed such that the shortest distance from the right wall 13 to rack 200D is between 0 cm and 5 cm, but is not limited to this. Rack 200D is installed such that the shortest distance from the front wall 11 to rack 200D is between 0 cm and 5 cm, but is not limited to this.

[0177] There is no aisle A in front of or behind rack 200D. Rack 200D is the first rack.

[0178] The first guide rail 171C and the first guide rail 171D are fixed to the floor F. Alternatively, the first guide rail 171C and the first guide rail 171D may be fixed to the recessed portion of the concave shape of the floor F. In this case, even if the first guide rail 171C and the first guide rail 171D are present on the floor F, it is less likely that a step will occur in the floor F.

[0179] The first guide rails 171C and 171D extend substantially perpendicular to the front wall 11 and the rear wall 14. The first guide rails 171C and 171D are installed so that the movable racks (rack 200B, rack 200D) are guided and can slide.

[0180] The first guide rails 171C and 171D are installed such that the shortest distance from the rear end of the first guide rail 171C and the rear end of the first guide rail 171D to the rack 200A is between 0 cm and 5 cm, but are not limited to this. In other words, the first guide rails 171C and 171D are installed such that the shortest distance from the rack 200B to the rack 200A can be between 0 cm and 5 cm.

[0181] The first guide rails 171C and 171D are installed such that the shortest distance from the front end of the first guide rail 171C and the front end of the first guide rail 171D to the rack 200D is between 0 cm and 5 cm, but are not limited to this. In other words, the first guide rails 171C and 171D are installed such that the shortest distance from the rack 200C to the rack 200D can be between 0 cm and 5 cm.

[0182] The depth of the first guide rail 171C and the depth of the first guide rail 171D are the sum of the depth of passage A, the depth of rack 200B, the depth of rack 200C, and a value between 0 cm and 15 cm, but are not limited to this.

[0183] The shortest distance from rack 200A to rack 200B is greater than or equal to the depth of aisle A. The shortest distance from rack 200B to rack 200C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 200C to rack 200D is between 0cm and 5cm, but is not limited to this value.

[0184] The second guide rails 172A and 172B are fixed to the ceiling 15. The second guide rails 172A and 172B extend substantially perpendicular to the front wall 11 and the rear wall 14. The second guide rails 172A and 172B are installed so that the movable racks (rack 200B, rack 200D) are guided and can slide.

[0185] The second guide rail 172A is provided opposite to the first guide rail 171C, but is not limited thereto. The second guide rail 172B is provided opposite to the first guide rail 171D, but is not limited thereto.

[0186] In the configurations of the rack system 20 shown in Figures 25 and 28 to 33, rack 200A, rack 200B, rack 200C, and rack 200D do not face the opening O.

[0187] Since the shortest distance from racks 200B and 200C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

[0188] This section describes a configuration of the rack system 20 that differs from the configurations of the rack system 20 shown in Figures 25 and 28 to 33. Figure 34 is a perspective view showing the overall configuration of equipment 2. Figure 35 is a left side view showing the detailed configuration of the rack system 20. Figure 36 is a right side view showing the detailed configuration of the rack system 20. Figure 37 is a top view showing the detailed configuration of the rack system 20. Figure 38 is a schematic configuration diagram showing the configuration of equipment 2 excluding four racks (rack 200A, rack 200B, rack 200C, and rack 200D). The front and rear views showing the detailed configuration of the rack system 20 are the same as those in Figures 28 and 29 and are therefore omitted.

[0189] There is no aisle A in front of or behind rack 200A. Rack 200A is the first rack. There is an aisle A in front of rack 200B. However, there is no aisle A behind rack 200B. There is an aisle A behind rack 200C. However, there is no aisle A in front of rack 200C. There is no aisle A in front of or behind rack 200D. Rack 200D is the first rack.

[0190] The shortest distance from rack 200A to rack 200B is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 200B to rack 200C is greater than or equal to the depth of aisle A. The shortest distance from rack 200C to rack 200D is between 0cm and 5cm, but is not limited to this value.

[0191] Racks 200A, 200C, and 200D do not face opening O. Rack 200B faces opening O.

[0192] Since the shortest distance from racks 200B and 200C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

[0193] This section describes configurations of the rack system 20 that differ from those shown in Figures 25 and 28 to 33, and those shown in Figures 34 to 38. Figure 39 is a perspective view showing the overall configuration of equipment 2. Figure 40 is a left side view showing the detailed configuration of rack system 20. Figure 41 is a right side view showing the detailed configuration of rack system 20. Figure 42 is a top view showing the detailed configuration of rack system 20. Figure 43 is a schematic configuration diagram showing the configuration of equipment 2 excluding four racks (rack 200A, rack 200B, rack 200C, and rack 200D). The front and rear views showing the detailed configuration of rack system 20 are the same as those in Figures 28 and 29, and are therefore omitted.

[0194] There is no aisle A in front of or behind rack 200A. Rack 200A is the first rack. There is no aisle A in front of or behind rack 200B. Rack 200B is the first rack. There is an aisle A in front of rack 200C. However, there is no aisle A behind rack 200C. There is an aisle A behind rack 200D. Rack 200D is the second rack.

[0195] The shortest distance from rack 200A to rack 200B is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 200B to rack 200C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 200C to rack 200D is greater than or equal to the depth of aisle A.

[0196] Racks 200A, 200C, and 200D do not face opening O. Rack 200B faces opening O.

[0197] Since the shortest distance from racks 200B and 200C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

[0198] (2-2) Control device The detailed configuration of the control device 29 will now be described. Figure 44 is a functional block diagram of the control device 29. The control device 29 mainly comprises a reception unit 291 and a movement control unit 292.

[0199] (2-2-1) Reception Department 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 the plant P to be purchased. For example, the reception unit 291 receives purchase orders from a terminal. Examples of terminals include, but are not limited to, mobile terminals (smartphones, mobile devices, tablet devices, laptops, wearable devices, etc.), desktop personal computers, touch panels, and POS (Point of Sales) terminals.

[0200] Furthermore, the reception unit 291 may receive at least one of the following from a server or cloud via the network: work information, completion information, and purchase orders.

[0201] (2-2-2) Mobile Control Unit The movement control unit 292 controls racks 200B and 200C to move approximately perpendicular to the front wall 11 based on work information. The movement control unit 292 also controls racks 200B and 200C to move approximately perpendicular to the front wall 11 based on completion information so that racks 200A, 200B, 200C, and 200D do not face the opening O. Furthermore, the movement control unit 292 further controls racks 200B and 200C to move approximately perpendicular to the front wall 11 based on a purchase order to secure passage A related to the purchase order.

[0202] The control of the movement control unit 292 will be explained below, divided into control based on work information, control based on completion information, and control based on purchase orders.

[0203] (2-2-2-1) Control based on work information When work information is received indicating that the target of the first work is the rear side of rack 200A or rack 200B, the movement control unit 192 controls racks 200B and 200C so that the configurations of the rack system 20 shown in Figures 25 and 28 to 33 are realized.

[0204] If the configurations of the rack system 20 shown in Figures 25 and 28 to 33 have already been implemented, the movement control unit 292 will not move racks 200B and 200C. Racks 200C and 200D will remain as the first rack. Rack 200A will remain as the second rack.

[0205] In the configuration of the rack system 20 shown in Figures 34 to 38, the movement control unit 292 moves rack 200B in approximately the X direction. As a result, rack 100A, which is the first rack, becomes the second rack. Rack 200D remains the first rack.

[0206] In the configuration of the rack system 20 shown in Figures 39 to 43, the movement control unit 292 moves racks 200B and 200C in approximately the X direction. As a result, the first rack, rack 200A, becomes the second rack, and the second rack, rack 200D, becomes 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 racks 200B and 200C so that the configurations of the rack system 20 shown in Figures 34 to 38 are realized.

[0208] In the configuration of the rack system 20 shown in Figures 25 and 28 to 33, the movement control unit 292 moves rack 200B in approximately the negative X direction. As a result, rack 200A, which is the second rack, becomes the first rack. Rack 200D remains the first rack.

[0209] If the configurations of the rack system 20 shown in Figures 34 to 38 have already been implemented, the movement control unit 292 will not move racks 200B and 200C. Racks 200A and 200D will remain as the first rack.

[0210] In the configuration of the rack system 20 shown in Figures 39 to 43, the movement control unit 292 moves rack 200C in approximately the X direction. As a result, rack 200D, which is the second rack, becomes the first rack. 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 racks 200B and 200C so that the configurations of the rack system 20 shown in Figures 39 to 43 are realized.

[0212] In the configuration of the rack system 20 shown in Figures 25 and 28 to 33, the movement control unit 292 moves racks 200B and 200C in approximately the negative X direction. The first rack, rack 200D, is replaced by the second rack. The second rack, rack 200A, is replaced by the first rack.

[0213] In the configuration of the rack system 20 shown in Figures 34 to 38, the movement control unit 292 moves rack 200C in approximately the negative X direction. Rack 200D, which is the first rack, changes into the second rack. Rack 200A remains the first rack and does not change.

[0214] If the configurations of the rack system 20 shown in Figures 39 to 43 have already been implemented, the movement control unit 292 will not move racks 200B and 200C. Racks 200A and 200B will remain as the first rack. Rack 200D will remain as the second rack.

[0215] In rack system 20, the first rack always exists regardless of where the movable racks (rack 200B, rack 200C) are moved. The configuration of rack system 20 is not limited to the configurations shown in Figures 25 and 28 through 43. Various configurations can be realized by having the movable racks slide guided by the first guide rails 171C and 171D, and the second guide rails 172A and 172B.

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

[0217] If the configurations of the rack system 20 shown in Figures 25 and 28 to 33 have already been implemented, the movement control unit 292 does not move racks 200B and 200C. If the configurations of the rack system 20 shown in Figures 34 to 38 are implemented, the movement control unit 292 moves rack 200B in approximately the X direction. If the configurations of the rack system 20 shown in Figures 39 to 43 are implemented, the movement control unit 292 moves racks 200B and 200C in approximately the X direction.

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

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

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

[0221] (3) Operation The operation of equipment 2 in the case where a person or device performs the first operation and when a purchase order is accepted will be described below. In the following operations, the configuration of rack system 20 is the configuration of rack system 20 shown in Figures 25 and 28 to 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 is an environment suitable for cultivating plants P.

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

[0223] The passage A for rack 200A is already secured. Person or equipment moves in front of rack 200A via entrance / exit 121 and passage A. Person or equipment begins the first operation on rack 200A. After the first operation on rack 200A is completed, since the passage A on the rear side of rack 200B is also already secured, person or equipment begins the first operation on the rear side of rack 200B. After the first operation on the rear side of rack 200B is completed, person or equipment leaves passage A.

[0224] A person or device inputs work information to the control device 29 indicating that the target of the first work is the front of rack 200B. The reception unit 291 receives the work information indicating that the target of the first work is the front of rack 200B. The movement control unit 292 moves rack 200B in approximately the negative X direction (step S11). As a result, the movement control unit 292 realizes the configuration of the rack system 20 shown in Figures 34 to 38.

[0225] A person or device moves in front of rack 200B via aisle A. The person or device begins the first operation on the front of rack 200B. After the first operation on the front of rack 200B is completed, since aisle A on the rear side of rack 200C is already clear, the person or device begins the first operation on the rear side of rack 200C. After the first operation on the rear side of rack 200C is completed, the person or device leaves aisle A.

[0226] A person or device inputs work information to the control device 29 indicating that the target of the first work is the front of rack 200C. The reception unit 291 receives the work information indicating that the target of the first work is the front of rack 200C. The movement control unit 292 moves rack 200C in approximately the negative X direction (step S12). As a result, the movement control unit 292 realizes the configuration of the rack system 20 shown in Figures 39 to 43.

[0227] The person or equipment moves in front of rack 200C via aisle A. The person or equipment begins the first operation on the front of rack 200C. After the first operation on the front of rack 200C is completed, since aisle A for rack 200D is also already cleared, the person or equipment begins the first operation on rack 200D. After the first operation on rack 200D is completed, the person or equipment leaves aisle A.

[0228] A person or device inputs end information to the control device 29. The reception unit 291 receives the end information. The movement control unit 292 moves the racks 200B and 200C substantially in the X direction (step S13). Thereby, the movement control unit 292 realizes the modes of the rack system 20 from FIGS. 25 and 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 received FIG. 46 is a flowchart showing the operation of the facility 2 when a purchase order is received. A user who purchases the plant P inputs a purchase order for the plant P to the terminal. The purchase order indicates that the position of the plant P to be purchased is in front of the rack 200C. The purchase order is transmitted from the terminal to the control device 29. The reception unit 291 receives the purchase order (step S21).

[0230] The movement control unit 292 moves the racks 200B and 200C substantially in the minus X direction so that the modes of the rack system 20 from FIGS. 39 to 43 are realized (step S22).

[0231] A person or device moves in front of the rack 200C through the entrance / exit 121 and the passage A. A person or device starts the harvesting operation for the plant P related to the purchase order. A person or device harvests the plant P related to the purchase order. After the harvesting operation for the plant P related to the purchase order is completed, the person or device leaves the passage A.

[0232] A person or device inputs end information to the control device 29. The reception unit 291 receives the end information. The movement control unit 292 moves the racks 200B and 200C substantially in the X direction so that the modes of the rack system 20 from FIGS. 25 and 28 to FIG. 33 are realized (step S23). 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 is further provided with a second guide rail 172A and a second guide rail 172B, which are fixed to the ceiling 15 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 171C and the first guide rail 171D, and the second guide rail 172A and the second guide rail 172B, so as to move in a direction substantially perpendicular to the first vertical wall.

[0234] In order to utilize the space in the vertical direction (Y direction), a tall movable rack is used. A tall movable rack may be structurally unstable during movement. The rack system 20 also uses the second guide rail 172A and the second guide rail 172B fixed to the ceiling 15 to move the movable rack. The rack system 20 facilitates the utilization of the vertical space and can achieve space saving and energy saving for cultivating the plant P.

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

[0236] When the movable rack moves forward in the movable rack, the passage in front of the movable rack disappears, and the passage behind the movable rack is secured. The space modes on both sides of the front side and the rear side of the movable rack change. Therefore, when the movable rack is moved with a passage secured from one side (for example, the front side of the movable rack), the passage of the movable rack may be secured again from the other side (for example, the rear side of the movable rack). Such a passage may be wasted.

[0237] In the rack system 20, the racks 200B and 200C are third racks that require a passage A from both sides of the front wall 11 side and the rear wall 14 side. Therefore, the rack system 20 can improve the efficiency of the movement of the movable rack and can further achieve energy saving for the plant P.

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

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

[0240] In rack system 20, rack 200D, which is closest to the front wall 11, and rack 200A, which is closest to the rear wall 14, are not the third rack. Therefore, rack system 20 can secure passage A, which can function as a passage on both sides. In addition, rack system 20 can limit the number of movable racks to a portion, and shorten the travel distance of the movable racks. Consequently, rack system 20 can achieve further energy savings.

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

[0242] There are times when immediate action is required for purchase orders of plants grown on racks. If a person has to verify the purchase order details and control the movable racks based on those details, the control process is time-consuming and labor-intensive.

[0243] When a purchase order is received, the control device 29 controls the system to secure the passage A for the purchase order. As a result, the control device 29 can reduce the processing time and effort required for the purchase order.

[0244] (5) Variant Regarding the modified version of the second embodiment, we will omit explanations of points that are the same as those of the second embodiment and focus on explaining the differences from the second embodiment.

[0245] (5-1) Modification 2A The reception unit 291 may receive movement information from a person or device via an input device (not shown). The reception unit 291 may also receive movement information from a server or cloud via a network.

[0246] (5-2) Modification 2B Equipment 2 does not necessarily need to be equipped with a control device 29. In this case, the possible rack is moved manually in a direction approximately perpendicular to the front wall 11.

[0247] (5-3) Modification 2C Facility 2 may be equipped with a greenhouse 2000 instead of a plant factory 1000. Alternatively, Facility 2 may be equipped with a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of a greenhouse 2000. The greenhouse 2000 may or may not be a building.

[0248] A rack system 20 is mainly provided inside the greenhouse I2 of the vinyl greenhouse 2000. The rack system 20 is the same as the rack system 20 of the second embodiment, the embodiment of modified example 2A, and the embodiment of modified example 2B.

[0249] The greenhouse 2000 mainly consists of 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 structure and function of the components of the greenhouse 2000 are the same as in the second embodiment, except for the shape of the ceiling 15, so a description is omitted.

[0250] (5-4) Modified example 2D (5-4-1) Structure Instead of the plant factory 1000, the device 2 may be equipped with a mushroom cultivation facility 3000. Inside the mushroom cultivation facility 3000, a rack system 20 is mainly provided. The rack system 20 is the same as any of the rack systems 20 in the second embodiment, the modified example 2A embodiment, and the modified example 2B embodiment, except that mushrooms M are cultivated in the racks instead of plants P.

[0251] The mushroom cultivation facility 3000 mainly includes 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 illuminations (not shown). Since the structure and function of the components of the mushroom cultivation facility 3000 are the same as those in the second embodiment, the description thereof is omitted.

[0252] Four racks (rack 200A, rack 200B, rack 200C, rack 200D) are placed with mycelium bottles B. Mushrooms M are cultivated in the mycelium bottles B. Note that the mushrooms M may be cultivated in mycelium beds instead of the mycelium bottles B. Note that the mushrooms M may be cultivated on trees instead of the mycelium bottles B.

[0253] The first operation is a mushroom operation on the mushrooms M by a person or a device. The passage A is used by a person or a device when the mushroom operation is performed. The purchase order is information indicating the position 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 three or more racks. When the reception unit 291 receives a purchase order, the movement control unit 292 further controls the movable rack to move in a direction substantially perpendicular to the first vertical wall so as to secure the passage A related to the purchase order among the three or more racks.

[0255] There may be a need for an immediate response to a purchase order for mushrooms cultivated in the racks. The control device 29 can shorten the working time required for the purchase order and reduce the labor.

[0256] (5-5) Modified Example 2E (5-5-1) Structure Facility 2 may include a warehouse 4000 instead of a plant factory 1000. Inside the warehouse 4000, I4, a rack system 20 is mainly provided. The rack system 20 is the same as the rack system 20 of the second embodiment, the embodiment of modification 2A, and the embodiment of modification 2B, except that instead of plants P being cultivated on the racks, goods G are stored there. Goods G include goods packaged in cardboard boxes or the like.

[0257] Warehouse 4000 mainly consists of 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 structure and function of the components of warehouse 4000 are the same as in the second embodiment, so a description is omitted.

[0258] The first operation is warehouse work performed on product G by people or equipment (robots, vehicles, etc.). Aisle A is used by people or equipment when warehouse work is performed. A purchase order is information indicating the location of product G to be purchased.

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

[0260] In some cases, immediate action is required for purchase orders of products stored in racks. The control device 29 can reduce the processing time and effort involved in handling purchase orders.

[0261] <Third Embodiment> (1) Overall structure The overall configuration of the equipment 3 according to the third embodiment will be described below. Hereinafter, similarities between the first and third embodiments will be omitted, and the differences between the first and third embodiments will be the focus of the description. Figure 47 is a perspective view showing the overall configuration of equipment 3. Equipment 3 mainly comprises a plant factory 1000, sensors Y1 and Y2, and a control device 39.

[0262] (1-1) Plant factory A rack system 30 is mainly installed inside the plant factory 1000, I1. Details of the rack system 30 will be described later. The configuration of the plant factory 1000 is the same as in the first embodiment, except for openings O1 and O2, so a description will be omitted.

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

[0264] Furthermore, openings O1 and O2 may also 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. Furthermore, openings O1 and O2 are not required to be provided. Moreover, 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 located inside I1. In other words, openings O1 and O2 may be air outlets of an air conditioner located inside I1. Furthermore, the number of openings is not limited to two (openings O1 and O2). There may be three or more openings.

[0265] (1-2) Sensor Sensors Y1 and Y2 detect the presence of a person or device in passage A and generate detection information. Examples of sensors Y1 and Y2 include, but are not limited to, infrared sensors, image sensors, thermal sensors, and electromagnetic sensors. The detection information indicates the presence of a person or device in passage A. The detection information may also indicate whether or not a person or device is present in passage A.

[0266] Sensors Y1 and Y2 are provided on the left wall 12, but are not limited to this location. Sensors Y1 and Y2 may be provided in other locations where the presence of a person or device in the passage A can be detected. For example, sensors Y1 and Y2 may be provided on at least one of the floor F, the right wall 13, the ceiling 15, and each rack of the rack system 30.

[0267] (1-3) Control device The control device 39 primarily controls the rack system 30. The control device 39 connects to the rack system 30 by wire or wireless connection. Details of the control device 39 will be described later. The control device 39 may be installed on internal I1. The control device 39 may be installed on a server or in the cloud. The control device 39 may be connected to rack systems 30 installed in multiple plant factories 1000.

[0268] (2) Detailed configuration (2-1) Rack System The detailed configuration of rack system 30 is described below. Rack system 30 mainly consists of racks 300A, 300B, 300C, and 300D. Note that the number of racks in rack system 30 does not need to be more than three, but is not limited to four.

[0269] The structure of rack 300A and the structure of rack 300D are approximately symmetrical with respect to the planes extending in the Y and Z directions. The structure of rack 300B and the structure of rack 300C are the same. The function of rack 300A and the function of rack 300D are the same. The function of rack 300B and the function of rack 300C are the same. The structure and function of rack 300A and rack 300B will be described below.

[0270] (2-1-1) Rack 300A Figure 48 is a perspective view showing the detailed configuration of rack 300A. Rack 300A has a plurality of stands S arranged substantially perpendicular to the floor F. For example, rack 300A has six stands S arranged substantially perpendicular to the floor F. Plants P are cultivated on each stand S. Plants P are planted in soil (not shown) on rack 300A or immersed in nutrient solution (not shown) on rack 300A. Rack 300A may be provided with lighting devices (not shown) that serve as a light source for plants P. Rack 300A is not a movable rack.

[0271] (2-1-2) Rack 300B Figure 49 is a perspective view showing the detailed configuration of rack 300B. Rack 300B has a plurality of stands S arranged substantially perpendicular to the floor F. For example, rack 300B has six stands S arranged substantially perpendicular to the floor F. Plants P are cultivated on each stand S. Plants P are planted in soil (not shown) on rack 300B or immersed in nutrient solution (not shown) on rack 300B. Rack 300B may be provided with lighting devices (not shown) that serve as a light source for plants P.

[0272] Furthermore, rack 300B is equipped with the following wheels: 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.

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

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

[0275] As the first wheels 181A, 181B, 181C, 181D, 2nd wheels 182A, 2nd wheels 182B, 2nd wheels 182C, and 2nd wheels 182D rotate, the rack 300B moves in a direction approximately perpendicular to the front wall 11. The rack 300B is a movable rack.

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

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

[0278] Rack 300A is approximately parallel to the front wall 11 and the rear wall 14. Rack 300A is the rack that is located at the shortest distance in the direction approximately perpendicular to the rear wall 14. Rack 300A is elongated in the direction approximately horizontal to the extension of the front wall 11, due to racks 300B and 300C.

[0279] Rack 300A is installed such that the shortest distance from the left wall 12 to rack 300A is between 0 cm and 5 cm, but is not limited to this. Rack 300A is installed such that the shortest distance from the right wall 13 to rack 300A is between 0 cm and 5 cm, but is not limited to this. Rack 300A is installed such that the shortest distance from the rear wall 14 to rack 300A is between 0 cm and 5 cm, but is not limited to this.

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

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

[0282] Rack 300B is installed such that the shortest distance from the left wall 12 to rack 300B is greater than or equal to the depth of passage A, but is not limited to this. Rack 300B is installed such that the shortest distance from the right wall 13 to rack 300B is between 0 cm and 5 cm, but is not limited to this.

[0283] Aisle A does not exist in front of rack 300B. Behind rack 300B, there is space, but it does not extend to the depth of aisle A. Therefore, aisle A does not exist behind rack 300B either. Rack 300B is the first rack.

[0284] Rack 300C is approximately parallel to the front wall 11 and the rear wall 14. The direction of movement of rack 300C is approximately perpendicular to the front wall 11. Therefore, even when rack 300C is moved, it remains approximately parallel to the front wall 11 and the rear wall 14. Rack 300C is shorter in the approximately horizontal direction in which the front wall 11 extends due to racks 300A and 300D.

[0285] Rack 300C is installed such that the shortest distance from the left wall 12 to rack 300C is greater than or equal to the depth of passage A, but is not limited to this. Rack 300C is installed such that the shortest distance from the right wall 13 to rack 300C is between 0 cm and 5 cm, but is not limited to this.

[0286] There is no aisle A behind rack 300C. There is space in front of rack 300C, but it is not deep enough for aisle A. Therefore, aisle A does not exist in front of rack 300C either. Rack 300C is the first rack.

[0287] Rack 300D is approximately parallel to the front wall 11 and the rear wall 14. Rack 300D is the rack that is located at the shortest distance in the direction approximately perpendicular to the front wall 11. Rack 300D is elongated in the direction approximately horizontal to the extension of the front wall 11, due to racks 300B and 300C.

[0288] Rack 300D is installed such that the shortest distance from the left wall 12 to rack 300D is between 0 cm and 5 cm, but is not limited to this. Rack 300D is installed such that the shortest distance from the right wall 13 to rack 300D is between 0 cm and 5 cm, but is not limited to this. Rack 300D is installed such that the shortest distance from the front wall 11 to rack 300D is between 0 cm and 5 cm, but is not limited to this.

[0289] Behind rack 300D, there is space, but it does not extend to the depth of aisle A. Therefore, aisle A does not exist behind rack 300D. Rack 300D is the first rack.

[0290] The shortest distance from rack 300B to rack 300C is between 0cm and 5cm, but is not limited to this value.

[0291] Racks 300A, 300B, 300C, and 300D do not face openings O1 and O2.

[0292] Since the shortest distance from racks 300B and 300C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

[0293] This section describes a configuration of rack system 30 that differs from the configurations of rack system 30 shown in Figures 47 and 50 to 55. Figure 56 is a perspective view showing the overall configuration of equipment 3. Figure 57 is a left side view showing the detailed configuration of rack system 30. Figure 58 is a right side view showing the detailed configuration of rack system 30. Figure 59 is a top view showing the detailed configuration of rack system 30. Figure 60 is a schematic configuration diagram showing the configuration of equipment 3 excluding four racks (rack 300A, rack 300B, rack 300C, and rack 300D). The front and rear views showing the detailed configuration of rack system 30 are the same as those in Figures 50 and 51 and are therefore omitted.

[0294] Aisle A exists in front of rack 300A. Rack 300A is the second rack. Aisle A exists behind rack 300B. Rack 300B is the second rack. Aisle A does not exist in front of or behind rack 300C. Rack 300C is the first rack. Aisle A does not exist in front of or behind rack 300D. Rack 300D is the first rack.

[0295] The shortest distance from rack 300A to rack 300B is greater than or equal to the depth of aisle A. The shortest distance from rack 300B to rack 300C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 300C to rack 300D is between 0cm and 5cm, but is not limited to this value.

[0296] Racks 300A, 300B, 300C, and 300D do not face opening O1. Racks 300A, 300B, and 300D do not face opening O2. Rack 300C faces opening O2.

[0297] Since the shortest distance from racks 300B and 300C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

[0298] This section describes a configuration of the rack system 30 that differs from the configurations of the rack system 30 shown in Figures 47 and 50 to 55, and the configurations of the rack system 30 shown in Figures 56 to 60. Figure 61 is a perspective view showing the overall configuration of equipment 3. Figure 62 is a left side view showing the detailed configuration of the rack system 30. Figure 63 is a right side view showing the detailed configuration of the rack system 30. Figure 64 is a top view showing the detailed configuration of the rack system 30. Figure 65 is a schematic configuration diagram showing the configuration of equipment 3 excluding four racks (rack 300A, rack 300B, rack 300C, and rack 300D). The front and rear views showing the detailed configuration of the rack system 30 are the same as those in Figures 50 and 51, and are therefore omitted.

[0299] There is no aisle A in front of rack 300A. Rack 300A is the first rack. There is no aisle A in front of or behind rack 300B. Rack 300B is the first rack. There is an aisle A in front of rack 300C. Rack 300C is the second rack. There is an aisle A behind rack 300D. Rack 300D is the second rack.

[0300] The shortest distance from rack 300A to rack 300B is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 300B to rack 300C is between 0cm and 5cm, but is not limited to this value. The shortest distance from rack 300C to rack 300D is greater than or equal to the depth of aisle A.

[0301] Racks 300A, 300B, 300C, and 300D do not face opening O2. Racks 300A, 300C, and 300D do not face opening O1. Rack 300B faces opening O1.

[0302] Since the shortest distance from racks 300B and 300C to the left wall 12 is greater than the depth of passage A, a path from passage A to entrance / exit 121 is also secured.

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

[0304] (2-2-1) Receiver The receiving unit 390 receives detection information from sensors Y1 and Y2.

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

[0306] The reception unit 391 may receive at least one of the following from a server or cloud via the network: work information, completion information, and start information. The start information may include information that associates the start time with at least one of the following: year, month, day, day, and day of the week.

[0307] (2-2-3) Mobile Control Unit The movement control unit 392 controls racks 300B and 300C to move approximately perpendicular to the front wall 11 based on work information. Before the start time, the movement control unit 392 controls racks 300B and 300C to move approximately perpendicular to the front wall 11 to secure passage A for the rack that is the target of the first work. Based on completion information, the movement control unit 392 controls racks 300B and 300C to move approximately perpendicular to the front wall 11 so that racks 300A, 300B, 300C, and 300D do not face openings O1 and O2. When the receiving unit 390 receives detection information, the movement control unit 392 controls racks 300B and 300C not to move approximately perpendicular to the front wall 11.

[0308] The control of the movement control unit 392 will be explained below, divided 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 is received indicating that the target of the first work is rack 300A or 300B, the movement control unit 392 controls racks 300B and 300C so that the configurations of the rack system 30 shown in Figures 56 to 60 are realized.

[0310] In the configuration of the rack system 30 shown in Figures 47 and 50 to 55, the movement control unit 392 moves racks 300B and 300C in approximately the X direction. As a result, the first racks, racks 300A and 300B, become the second racks. Racks 300C and 300D remain the first racks.

[0311] If the configurations of the rack system 30 shown in Figures 56 to 60 have already been implemented, the movement control unit 392 will not move racks 300B and 300C. Racks 300C and 300D will remain as the first rack. Racks 300A and 300B will remain as the second rack.

[0312] In the configuration of the rack system 30 shown in Figures 61 to 65, the movement control unit 392 moves racks 300B and 300C in approximately the X direction. As a result, the first racks, racks 300A and 300B, become the second racks. The second racks, racks 300C and 300D, become the first racks.

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

[0314] In the configuration of the rack system 30 shown in 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 the second racks. Racks 300A and 300B remain the first racks.

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

[0316] If the configurations of the rack system 10 shown in Figures 61 to 65 have already been implemented, the movement control unit 392 will not move racks 300B and 300C. Racks 300A and 300B will remain as the first rack. Racks 300C and 300D will remain as the second rack.

[0317] In the rack system 30, the first rack always exists regardless of where the movable racks (rack 300B, rack 300C) are moved. The configuration of the rack system 30 is not limited to the configurations shown in Figures 47 and 50 to 65. By rotating the first wheels 181A, 181B, 181C, 181D, 2nd wheels 182A, 2nd wheels 182B, 2nd wheels 182C, and 2nd wheels 182D, the movable rack can be moved, enabling various configurations.

[0318] (2-2-3-2) Control based on start information The movement control unit 392 reads the start information from the storage unit 393. Based on the start information, the movement control unit 392 identifies the start time and the rack to be targeted for the first operation. Before the start time, the movement control unit 392 controls racks 300B and 300C to move substantially perpendicular to the front wall 11 to secure passage A to the rack to be targeted for the first operation. An example of a time before the start time is, but is not limited to, 30 seconds to 5 minutes before the start time.

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

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

[0321] If the configurations of the rack system 30 shown in Figures 47 and 50 to 55 have already been implemented, the movement control unit 392 does not move racks 300B and 300C. If the configurations of the rack system 30 shown in Figures 56 to 60 are implemented, the movement control unit 392 moves racks 300B and 300C in approximately the negative X direction. If the configurations of the rack system 30 shown in Figures 61 to 65 are implemented, the movement control unit 392 moves racks 300B and 300C in approximately the X direction.

[0322] (2-2-3-4) Control based on detection information When the receiving unit 390 receives detection information, the movement control unit 392 controls racks 300B and 300C to prevent them from moving. Control based on detection information takes precedence over other controls. In other words, control based on detection information takes precedence over control based on work information, control based on start information, and control based on end information. Therefore, if a person or device is present in passage A, the movement control unit 392 does not perform control based on work information, control based on start information, or control based on end information, and controls racks 300B and 300C to prevent them from moving.

[0323] (2-2-4) Storage section The memory unit 393 stores start information. Examples of memory units 393 include HDDs (Hard Disk Drives) and SSDs (Solid State Drives).

[0324] (3) Operation The operation of equipment 3 when a person or device performs the first operation will be described. Start information is pre-recorded in the storage unit 393. The start information indicates that the start time is 8:00 and the target of the first operation is rack 300A. The first operation is performed in the order of rack 300A, rack 300B, rack 300C, and rack 300D. Figure 67 is a flowchart of the operation of equipment 3. The configurations of rack system 30 are shown in Figures 47 and 50 to 55.

[0325] Warm air is supplied to the interior I1 through openings O1 and O2. As a result, the interior I1 maintains a higher temperature than the exterior of the plant factory 1000. The interior I1 provides an environment suitable for cultivating plant P.

[0326] The movement control unit 392 reads the start information from the storage unit 393. The movement control unit 392 identifies that the start time is 8:00 and that the target of the first operation is rack 300A.

[0327] At 7:57, three minutes before the start time, the movement control unit 392 moves racks 300B and 300C in approximately the X direction (step S31). This allows the movement control unit 392 to realize the configuration of the rack system 30 shown in Figures 56 to 60. Note that step S31 is not limited to three minutes before the start time; it should be performed at a time that allows for the securing of aisle A for the racks targeted by the first operation before the start time.

[0328] At the start time (8:00), the person or equipment can move in front of rack 300A via aisle A, which is already reserved. The person or equipment begins the first task on rack 300A. After the first task on rack 300A is completed, the person or equipment begins the first task on rack 300B, as aisle A for rack 300B is also reserved. After the first task on rack 300B is completed, the person or equipment leaves aisle A.

[0329] A person or device inputs work information to the control device 39 indicating that the target of the first work is rack 300C. 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 racks 300B and 300C in approximately the negative X direction (step S32).

[0330] A person or device moves in front of rack 300C via aisle A. The person or device begins the first operation on rack 300C. After the first operation on rack 300C is completed, aisle A for rack 300D is also cleared, so the person or device begins the first operation on rack 300D. After the first operation on rack 300D is completed, the person or device leaves aisle A.

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

[0332] (4) Features (4-1) The rack system 30 has first wheels 181A, 181B, 181C, and 181D attached to the movable rack, which are in contact with the floor F of another structure. The movable rack is moved in a direction approximately perpendicular to the first vertical wall by the rotation of the first wheels 181A, 181B, 181C, and 181D.

[0333] For the movable rack to be moved by the guide rail, the guide rail must be installed in advance. The movable rack of the rack system 30 is moved by the rotation of the first wheels 181A, 181B, 181C, and 181D. The rack system 30 can move the movable rack even without the installation of guide rails in advance.

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

[0335] The first wheels 181A, 181B, 181C, and 181D are rotated around a rotation axis that is substantially parallel to the front wall 11. The movable rack is moved substantially perpendicular to the front wall 11. As a result, the force acting on the movable rack is not dispersed, and the movable rack is moved efficiently substantially perpendicular to the front wall 11. This makes it easier for the rack system 30 to secure passage A to the rack.

[0336] (4-3) The rack system 30 is further equipped with second wheels 182A, 182B, 182C, and 182D on the movable rack, which are in contact with the ceiling 15 of another structure. The movable rack is moved in a direction approximately perpendicular to the first vertical wall by the rotation of the first wheels 181A, 181B, 181C, 181D, 2 wheels 182A, 2 wheels 182B, 2 wheels 182C, and 2 wheels 182D.

[0337] To utilize vertical space, tall movable racks are used. However, tall movable racks can be structurally unstable when moved. The rack system 30 moves the movable racks using second wheels 182A, 182B, 182C, and 182D that are in contact with the ceiling 15. The rack system 30 facilitates the utilization of vertical space and enables space and energy savings in the cultivation of plants 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 operation is to begin, the movable rack is moved in a direction substantially perpendicular to the first vertical wall to secure a passage A for the rack that is the target of the first operation among the three or more racks.

[0339] Moving the movable racks takes time. Therefore, the first operation may be delayed due to the movement of the movable racks. The control device 39 controls the system to secure passage A for the racks targeted by the first operation before the start time. This allows the control device 39 to reduce the time required to move the movable racks and improve the efficiency of the first operation.

[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 passage A from sensors Y1 and Y2, which detect the presence of a person or device in passage A. When the movement control unit 392 receives detection information, it further controls the movable rack so that it does not move in a direction substantially perpendicular to the first vertical wall.

[0341] If a movable rack is moved while a person or equipment is present in the passageway, it may result in injury to a person or damage to equipment. When the control device 39 receives detection information, it controls the movable rack to prevent it from moving. Therefore, the control device 39 can ensure the safety of people or equipment.

[0342] (4-6) The control device 39 has multiple openings (opening O1 and opening O2) in the other structure. After the first operation is completed, the movement control unit 392 further controls the movable racks to move substantially perpendicular to the first vertical wall so that no more than three racks face multiple openings.

[0343] When racks are installed in a dense arrangement, airflow may be difficult to form, potentially leading to temperature or humidity unevenness. Other structures have openings O1 and O2. The control device 39 controls the movable racks to move so that they do not face openings O1 and O2 after the first operation is completed. As a result, the control device 39 can reduce the possibility of temperature or humidity unevenness occurring due to airflow from multiple openings, and create an environment in the interior I1 that is more suitable for cultivating plants P.
