The scaffold 220 has a rectangular shape, for example, and is formed in a long shape along the width direction (longitudinal direction) of the outer protective cover 110. Although the scaffolding 220 may have at least two stages, it may be three stages, four stages, or five stages or more.

The tray 150 is also referred to as a seedling tray, a cultivation tray, a planting bed, a seedling bed, and the like for planting plants.

In each of the scaffoldings of the plurality of scaffolding 220, at least one tray 150 is disposed. In the present embodiment, as shown in Fig. 2, five trays 150 are disposed in one scaffold 220. Although five trays 150 can be arranged at an arbitrary interval on the scaffold 220, it is preferably fixed. The intervals are arranged on the scaffold 220.

The plant factory apparatus 100 of the present embodiment includes a horizontal movement mechanism 221 that moves the tray 150 in the longitudinal direction of the scaffold 220, and a vertical movement mechanism 230 that moves the tray 150 from the scaffolding to the vertical direction of the scaffold.

Further, the plant factory apparatus 100 includes a movable control unit 300 that intermittently moves the tray 150 by controlling the horizontal movement mechanism 221 and the vertical movement mechanism 230. The movable control unit 300 circulates the tray 150 inside the plant factory device 100 by intermittently moving the tray 150 to uniformize the cultivation environment of the plant 400 cultivated inside.

The movable control unit 300 is connected to the terminal device 500 via the network 600, for example. The manager (also referred to as a user) of the plant factory device 100 sends a control signal (control command 510) to the movable control unit 300 of the plant factory device 100 by the terminal device 500. Alternatively, the manager of the plant factory device 100 may input control to the movable control unit 300 from an input unit (not shown) provided in the plant factory device 100. Command 510.

The tray 150 forms an opening 151 for the nursery that is used to set the nursery of the plant 400. In the present embodiment, six nursery openings 151 are formed in one tray 150.

The length of the longitudinal direction of the tray 150 (hereinafter referred to as the longitudinal direction of the tray) is slightly shorter than the length of the short side of the scaffold 220. Further, the length of the short side direction of the tray 150 (hereinafter referred to as the short side direction of the tray) is, for example, about one-seventh of the length in the longitudinal direction of the scaffold 220. Thereby, the interval of about one-half of the length of the tray 150 in the short-side direction is provided, and five trays 150 can be placed on the scaffold 220.

However, the number of the trays 150 arranged in one scaffold 220 and the size of the tray 150 may be arranged at intervals other than the above, and the present embodiment can be applied to the number and size other than the above.

Further, it is preferable that the trays 150 have the same shape, but the present embodiment can be applied even if a tray having a different size or number of openings for the nursery is mixed.

Here, an example of a method of arranging the tray 150 on the scaffold 220 will be described.

For example, the scaffold 220 is formed of a rectangular frame portion. That is, the scaffolding 220 is only a frame and is generally open on the entire surface.

As shown in Fig. 1, the tray 150 is the side of the end portions on both sides in the longitudinal direction of the tray. The rim portion can be assembled by detaching the frame portion of the end portions on both sides in the short side direction of the scaffolding 220. As shown in Fig. 2, the inner surface (lower surface) of the tray 150 is exposed by the opening of the frame, and the root side of the stalk plant 400 provided with the plant 400 on the tray 150 is exposed by the surface below the tray 150.

As shown in Fig. 2, a nutrient solution basin 330 is provided in the lower portion of the lowermost scaffold 220a. In the nutrient solution basin 330, a nutrient solution containing nutrients required for cultivating the plant is introduced. The nutrient solution in the nutrient solution basin 330 is immersed by planting the root side of the plant 400 placed on the tray 150 of the scaffold 220a disposed at the lowermost stage to supply the nutrient solution to the plant 400.

In other words, the plant 400 of the tray 150 is absorbing the nutrient solution of the nutrient solution basin 330 when passing through the lowermost scaffold 220a.

In the above description, the scaffold 220 is formed only by the frame, but the structure in which the root side of the plant 400 planted in the tray 150 is exposed by the opening of the scaffold 220 and immersed in the nutrient solution of the nutrient solution basin 330 may be used. It is not just the construction of the frame.

For example, the scaffolding 220 may also be provided with a thin plate or the like across the short side direction of the frame. The durability of the scaffold 220 for weight is increased by arranging a thin plate or the like in the short side direction of each of the frames.

As shown in Fig. 2, the horizontal moving mechanism 221 is disposed in each of the scaffoldings 220a, 220b, 220c, and 220d. As shown in Fig. 2, the horizontal movement mechanism 221 is disposed at a position (horizontal movement mechanisms 221a, 221b, 221c, and 221d) surrounded by broken lines of the respective scaffolds 220a, 220b, 220c, and 220d. The horizontal movement mechanism 221 is a mechanism that moves the trays 150 disposed in the respective scaffolds 220a, 220b, 220c, and 220d toward the longitudinal direction of the scaffold 220 (hereinafter also referred to as the left-right direction).

The horizontal movement mechanism 221 can be realized, for example, by: In the frame portion forming the scaffold 220, a rail or a belt is disposed on the inner surface of the frame 225 (see the frame 225d extending in the longitudinal direction of the first drawing) that extends in the longitudinal direction. Direction guide. The left-right direction guide portion of the horizontal movement mechanism 221 is engaged with the edge portion of the end portions of the tray 150 on both sides in the longitudinal direction of the tray, and the end portions on both sides in the longitudinal direction of the tray of the tray 150 are guided by the left-right direction. The tray 150 moves in the left and right direction.

Further, as shown in Fig. 2, the vertical movement mechanism 230a is disposed between the scaffold 220a and the scaffold 220b. The vertical movement mechanism 230a is a mechanism for moving the tray 150 from the scaffold 220a toward the scaffold 220b.

The vertical movement mechanism 230b is disposed between the scaffold 220b and the scaffold 220c. The vertical movement mechanism 230b is a mechanism for moving the tray 150 from the scaffold 220b toward the scaffold 220c.

The vertical movement mechanism 230c is disposed between the scaffolding 220c and the uppermost scaffold 220d. The vertical movement mechanism 230c is a mechanism for moving the tray 150 from the scaffold 220c toward the scaffold 220d.

Further, as shown in Fig. 2, a vertical movement mechanism 230d that connects the scaffold 220d and the scaffold 220a is disposed. The vertical movement mechanism 230d is a mechanism for moving the tray 150 from the scaffold 220d toward the scaffold 220a, that is, the lower moving mechanism 240.

The vertical movement mechanism 230 can be realized, for example, by a vertical direction guide portion formed by a rail and a belt disposed in the vertical direction.

The vertical movement mechanism 230 moves the tray 150 that has moved to the position of the vertical direction guide in the vertical direction by the horizontal direction guide of the horizontal movement mechanism 221.

As shown in Fig. 2, the plant factory device 100 has four vertical moving mechanisms. 230a, 230b, 230c, 230d.

For example, when the tray 150 is moved to the position of the vertical direction guide by the movement of the right and left direction guides of the horizontal movement mechanism 221, the engagement with the right and left direction guides may fall off, and the up and down direction The guide is engaged. Then, the tray 150 is engaged with the vertical direction guiding portion, and is movable in the vertical direction by the vertical direction guiding portion.

When the tray 150 is moved to the other scaffold 220 by the movement of the up-and-down direction of the up-and-down moving mechanism 230, the engagement with the up-and-down direction guide portion is lost, and the left-right direction guide portion is stuck. Hehe. Then, the tray 150 is engaged with the right and left direction guides, and is moved in the left-right direction by the right and left direction guides.

Next, an environmental adjustment machine for appropriately maintaining the internal environment of the plant factory apparatus 100 will be described. The lower machine accommodating portion 120 shown in Fig. 2 is schematically illustrated for easy understanding of the internal configuration.

As shown in FIG. 2, in the lower machine storage unit 120, an environment adjustment device for appropriately maintaining the internal environment of the plant factory device 100 is housed. As shown in Fig. 1, it is also possible to store the environment adjustment device in the upper portion of the outer casing 110 and the machine storage portion 121.

On the inner side of the upper surface of the outer protective cover 110, a top surface LED light source 371 is disposed. For example, a lighting device, a power supply device, or the like for adjusting the amount of light of the top surface LED light source 371 may be housed in the upper device storage unit 121.

Further, on the inner surface of the tray 150, each segment of the LED light source 372 to which the waterproof structure has been applied is disposed. Each segment of the LED light source 372 can emit light required for photosynthesis to the plant 400 of the lower tray 150 in a state where the tray 150 is stopped.

In the second drawing, in order to facilitate the understanding of the respective LED light sources 372 on the inner surface of the tray 150, it is described that the inner surface (bottom surface) of the tray 150 is exposed to the lower side from the lower surface of the scaffold 220. However, the inner surface of the tray 150 and the lower surface of the scaffold 220 may have a positional relationship in substantially the same planar state. Alternatively, the position of the inner surface of the tray 150 at a position higher than the lower surface of the scaffolding 220 may be used.

The plant factory device 100 is housed in the lower device storage unit 120 as an air conditioner 310, a liquid fertilizer tank 320, a nutrient solution delivery pipe 322, an opening and closing valve 323 (automatic nutrient solution input machine), and an air mixer 360 as environmental adjustment devices.

Further, as described above, the plant factory apparatus 100 includes a horizontal movement mechanism 221 that moves the tray 150 in the longitudinal direction of the scaffold 220, and moves the tray 150 from the scaffolding to the vertical direction of the scaffold in the vertical direction.

The movable control unit 300 that controls the horizontal movement mechanism 221 and the vertical movement mechanism 230 is also housed in the lower device storage unit 120.

As shown in Fig. 1, the outer casing portion 112 of the lower machine storage portion 120 is an opaque plate material, and the design of the plant factory device 100 is improved by hiding the internal equipment.

The air conditioner 310 controls the temperature/humidity inside the plant factory device 100.

The liquid fertilizer tank 320 is a tank for storing nutrient solution. In the nutrient solution basin 330, the nutrient solution is supplied from the liquid fertilizer tank 320 via the nutrient solution delivery pipe 322.

The nutrient solution delivery tube 322 is provided with an on-off valve 323 (automatic nutrient solution input machine). For example, the opening and closing valve 323 (automatic nutrient solution input machine) is controlled by an external control command 510 to automatically adjust the nutrient solution input into the nutrient solution basin 330. the amount. Further, the configuration of the amount of the nutrient solution to be introduced into the nutrient solution basin 330 may be manually adjusted.

The air mixer 360 agitates the air inside the plant factory device 100 (outer protective cover 110). The air mixer 360 is provided with an air blowing port 361. The air mixer 360 is disposed at, for example, two places below the scaffolding 220a of the lowermost stage. Alternatively, the air mixer 360 may be disposed at three places or four places.

As shown in Fig. 3, the air mixer 360 blows air upward from the air blowing port 361, thereby agitating the air inside the outer protective cover 110. As described above, the temperature/humidity/CO ₂ /air volume inside the plant factory device 100 can be made uniform by the agitation of the air from the lower side to the upper side.

The air mixer 360 is oriented in a predetermined angle (α degree) from the normal direction P of the surface formed by the lowermost scaffold 220a, and the air is blown out by the air blowing port 361.

The air mixer 360 is, for example, directed to a range of 45 degrees (α=45 degrees) from the normal direction P, and air is blown by the air blowing port 361.

The angle of the air blown by the air mixer 360 is preferably within 45 degrees, but is also effective within 50 degrees and 60 degrees. Alternatively, the air mixer 360 may be set to three or more, and the air blowing angle may be set to be within 30 degrees.

As shown in Fig. 3, the air mixer 360 is blown out of the air blowing port 361 toward a predetermined angle (α degree), thereby effectively allowing air to pass through the plant factory device 100, and having the plant factory device The effect of environmental homogenization within 100.

Next, a method of performing tray movement control by the movable control unit 300 of the plant factory apparatus 100 will be described with reference to FIG.

As described above, the horizontal movement mechanism 221 and the vertical movement mechanism 230 move the tray 150 toward the longitudinal direction of the scaffold 220 in which the tray 150 is disposed by receiving the control, and the tray 150 is moved from the upper and lower scaffolds. An example of a tray moving mechanism in which one scaffold moves toward another scaffolding.

Further, the movable control unit 300 controls the horizontal movement mechanism 221 and the vertical movement mechanism 230 to repeat the operation in which the tray 150 is moved by the stopped state and stopped by the movement state. This is not controlled by the ON/OFF power supply, but is controlled by the mobile state being turned off (ON) and stopped by the mobile state. That is, the movable control unit 300 intermittently moves the tray 150.

The movable control unit 300 controls the horizontal movement mechanism 221 and the vertical movement mechanism 230 to intermittently move the tray 150, and causes the tray 150 to start moving from a predetermined position of any one of the plurality of scaffolds 220. And the movement moves over all the scaffoldings of the plurality of scaffoldings and returns to the predetermined position.

The movable control unit 300 repeatedly performs control for moving and stopping the tray 150 periodically or irregularly.

Next, a specific example in which the movable control unit 300 intermittently circulates the tray 150 will be described.

The user can send a control command 510 to the movable control unit 300 from the terminal device 500 via the network 600, for example. Alternatively, the plant factory device 100 may include an input unit that inputs a control command 510 to the movable control unit 300. Alternatively, the movable control program may be installed in advance in the movable control unit 300 of the plant factory device 100, and all of them may be automatically controlled.

The control command 510 can be selected, for example, as an intermittent mode or a continuous moving mode, and can set the moving time interval of the tray 150 in the intermittent mode, the tray 150 The speed of movement, etc.

The intermittent mode is a mode in which the movement of the tray 150 is repeated or stopped periodically or irregularly.

The continuous movement mode is a manner in which the tray 150 is continuously moved. A control command 510 for the continuous movement mode of the continuous movement mode may be input to the plant factory apparatus 100. By instructing the tray 150 to continuously move or stop moving, it is easy to arrange all the trays 150 (20 trays in Fig. 2) inside the plant factory apparatus 100 at the start of cultivation, which is true for the user. It is convenient.

The speed system can specify the actual speed, and can also be selected by a predetermined plurality of stages such as "fast, normal, slow". Moreover, in the intermittent mode, the periodic intermittent mode or the irregular intermittent mode can also be selected.

Further, the outer protective cover 110 is provided near the end of at least one of the plurality of scaffolds 220, and includes a sealed automatic opening and closing door 140 (see FIG. 1, FIG. 2, and FIG. 3). In the plant factory apparatus 100, there is a case where the plant 400 which has to be removed is defective. In this case, the user can use the continuous movement mode to move the defective plant 400 to be removed to the vicinity of the sealed automatic opening and closing door 140, and the defective plant 400 can be quickly taken out by the sealed automatic opening and closing door 140.

Here, the user is in the intermittent mode and the periodic mode, and the moving time interval is 1 hour, and the moving speed is designated as "normal". Further, in the intermittent mode and the irregular mode, for example, a time interval of a plurality of movements is input. Alternatively, when the time interval of one movement is input in the irregular mode, the movable control unit 300 may automatically and irregularly control according to the time interval of the input movement.

If it is in the intermittent mode and is in the periodic mode, the moving time interval is 1 hour, and when the moving speed is designated as "normal", the movable control unit 300 is used. The tray 150 (refer to Fig. 2) of P1 is moved from P1 to P2 after 1 hour, and then moved at a normal speed and then stopped. Then, after 2 hours, the movement from P2 to P3 is performed at a normal speed and then stopped. In the same manner, when moving from P3 to P4, from P4 to P5, ..., it returns to the position of P1 again in 20 hours.

In the same manner, the tray 150 (refer to Fig. 2) located at P2 is moved from P2 to P3 at a normal speed and then stopped after 1 hour.
