One of the plant cultivation shelves 11 is shielded from the light emitted from the light source 1. Further, the reflector 5 in the second state reflects the light emitted from the light source 1 on one side of the plant cultivation shelf 11 arranged with the light source 1 sandwiched therebetween, and is arranged with the light source 1 sandwiched therebetween. The other side of the plant cultivation shelf 11 is shielded from the light emitted from the light source 1. In the example shown in FIG. 4, the reflecting plate 5 1 in the first state, to reflect light emitted by the light source 1 1 on the side of the plant cultivation rack 11 2 and emits a plant cultivation rack 11 first light source 1 1 Shield from light. Further, the reflecting plate 5 1 in the second state, to reflect light source 1 1 emitted to the side of the plant cultivation rack 11 1, and to shield the plant cultivation rack 11 2 from the light source 1 1 is emitted. The reflection plate 5 2 in the first state, to reflect light source 1 2 is emitted to the side of the plant cultivation rack 11 2, and to shield the plant cultivation rack 11 3 from the light source 1 2 is emitted. The reflection plate 5 2 in the second state, to reflect light source 1 2 is emitted to the side of the plant cultivation rack 11 3, and to shield the plant cultivation rack 11 2 from the light source 1 2 is emitted.
図５は、実施の形態１に係る栽培装置の植物栽培棚の配置状態を示す図である。図５は、実施の形態１に係る栽培装置２０の一部分のみを図示している。図５に示すように積み重ねられた植物栽培棚１１に隣接して、投光部１２を配置する。さらに、投光部１２に隣接して植物栽培棚１１を配置し、投光部１２を隣接する二つの植物栽培棚１１で共有させる。このように、栽培装置２０は、交互に配置された植物栽培棚１１及び投光部１２を有する。
FIG. 5 is a diagram showing an arrangement state of the plant cultivation shelves of the cultivation device according to the first embodiment. FIG. 5 illustrates only a part of the cultivation device 20 according to the first embodiment. The light projecting unit 12 is arranged adjacent to the stacked plant cultivation shelves 11 as shown in FIG. Further, the plant cultivation shelf 11 is arranged adjacent to the light projecting unit 12, and the light projecting unit 12 is shared by the two adjacent plant cultivation shelves 11. As described above, the cultivation device 20 has the plant cultivation shelves 11 and the light projecting unit 12 that are alternately arranged.
図１に示したように、光源１及び反射板５は、隣接する植物栽培棚１１同士の間に配置される。回転軸８は、隣接する二つの植物栽培棚１１のどちらからも等しい距離に配置される。回転軸８を中心に反射板５を回転させることにより、光源１の光を照射する植物栽培棚１１を選択することができる。図６は、実施の形態１に係る栽培装置の使用時の状態を示す図である。複数の植物栽培棚１１が並ぶ植物工場では、図６に示すように明期となっている植物栽培棚１１と暗期となっている植物栽培棚１１が交互に並ぶように光源１の光を照射する植物栽培棚１１を選択する。明期となっている植物栽培棚１１と暗期となっている植物栽培棚１１とが交互に並ぶことにより、隣接する植物栽培棚１１間で光源１を共有でき、植物工場に設置する光源１の数を減らすことができる。実施の形態１に係る栽培装置２０は、明期と暗期との切り替えを部屋単位で行う栽培装置と比較して光源１の数を半分にした場合でも、植物栽培棚１１単位で明期と暗期の切り替え、光源１を常時点灯させることにより、同じ育成効率で植物４を栽培することができる。
As shown in FIG. 1, the light source 1 and the reflector 5 are arranged between adjacent plant cultivation shelves 11. The rotary shaft 8 is arranged at the same distance from both of the two adjacent plant cultivation shelves 11. By rotating the reflection plate 5 about the rotation axis 8, it is possible to select the plant cultivation shelf 11 to which the light from the light source 1 is irradiated. FIG. 6 is a diagram showing a state when the cultivation device according to the first embodiment is in use. In a plant factory in which a plurality of plant cultivation shelves 11 are lined up, as shown in FIG. 6, the light of the light source 1 is arranged so that the plant cultivation shelves 11 in the light period and the plant cultivation shelves 11 in the dark period are alternately arranged. The plant cultivation shelf 11 to be irradiated is selected. By alternately arranging the plant cultivation shelves 11 in the light period and the plant cultivation shelves 11 in the dark period, the light source 1 can be shared between the adjacent plant cultivation shelves 11, and the light source 1 installed in the plant factory The number of can be reduced. Even when the number of the light sources 1 is halved in comparison with the cultivation device that switches the light period and the dark period in a room unit, the cultivation device 20 according to the first embodiment makes the plant cultivation shelf 11 unit the light period. By switching the dark period and turning on the light source 1 at all times, the plant 4 can be cultivated with the same growth efficiency.
反射板５の断面形状が半円であり、回転軸８の位置が反射板５の断面の半円の中心と一致しているため、反射板５の回転時の回転半径を小さくでき、植物栽培棚１１と反射板５との干渉を発生させないために必要となる隣接する植物栽培棚１１間の間隔を小さくできる。また回転軸８を隣接する二つの植物栽培棚１１のどちらからも等しい距離に配置することで、植物４と光源１との距離を隣接する植物栽培棚１１間で等しくできる。これにより、植物栽培棚１１ごとに植物４の育成状態にむらが生じることを低減できる。
Since the cross-sectional shape of the reflector 5 is a semi-circle and the position of the rotation axis 8 is coincident with the center of the semi-circle of the cross-section of the reflector 5, the radius of gyration when the reflector 5 is rotated can be reduced, and plant cultivation can be performed. It is possible to reduce the interval between the adjacent plant cultivation shelves 11 which is necessary to prevent the interference between the shelves 11 and the reflection plate 5. Further, by disposing the rotating shaft 8 at the same distance from both of the two adjacent plant cultivation shelves 11, the distance between the plant 4 and the light source 1 can be made equal between the adjacent plant cultivation shelves 11. As a result, it is possible to reduce unevenness in the growing state of the plants 4 for each of the plant cultivation shelves 11.
実施の形態１に係る栽培装置２０は、光源１及び反射板５を互いに隣接する二つの植物栽培棚１１の間に設置し、一つの植物栽培棚１１に対し両側から光を照射することで照射むらを低減することができる。また、反射板５を回転させることで、光源１から開口部９を通じて植物４に直達光６及び反射光７が到達しないようにすることができ、暗期となる領域を確実に形成させることができる。
The cultivating apparatus 20 according to the first embodiment irradiates by irradiating the one light source 1 and the reflection plate 5 between two adjacent plant cultivation shelves 11 and irradiating one plant cultivation shelf 11 with light from both sides. The unevenness can be reduced. Further, by rotating the reflection plate 5, it is possible to prevent the direct light 6 and the reflected light 7 from reaching the plant 4 from the light source 1 through the opening 9, and it is possible to surely form a dark period region. it can.
また、実施の形態１に係る栽培装置２０は、光源１及び反射板５を植物４の上方に設置する場合に比べ、光源１及び反射板５の位置を下げることができ、植物栽培棚１１の一層当たりの高さサイズを小さくすることができる。したがって、植物栽培棚１１を複数段に設けた場合の植物栽培棚１１全体の高さを抑えることができ、上位段の植物栽培棚１１へのアクセス性及び視認性を維持することができる。
Further, the cultivating apparatus 20 according to the first embodiment can lower the positions of the light source 1 and the reflection plate 5 as compared with the case where the light source 1 and the reflection plate 5 are installed above the plant 4, and thus The height size per layer can be reduced. Therefore, when the plant cultivation shelves 11 are provided in a plurality of stages, it is possible to suppress the height of the entire plant cultivation shelves 11, and it is possible to maintain the accessibility and visibility to the upper-level plant cultivation shelves 11.
また、実施の形態１に係る栽培装置２０は、植物栽培棚１１と投光部１２とが上下方向に重なっておらず、各層において投光部１２を同じ位置に配置できるため、光源１及び反射板５への配線作業及びメンテナンス作業が容易となる。また、万が一、植物栽培棚１１から養液の漏れが生じた場合でも光源１及び反射板５に掛かることを大幅に低減できる。このため、光源１反射板５に養液が頻繁にかかり、故障の原因となったり、表面汚れによる光量不足の原因となったりすることを抑制できる。
In the cultivation device 20 according to the first embodiment, the plant cultivation shelf 11 and the light projecting unit 12 do not overlap each other in the vertical direction, and the light projecting unit 12 can be arranged at the same position in each layer. Wiring work to the plate 5 and maintenance work become easy. Further, even if the nutrient solution leaks from the plant cultivation shelf 11, it is possible to greatly reduce the light source 1 and the reflector 5 from being leaked. For this reason, it is possible to prevent the nutrient solution from being frequently applied to the light source 1 reflection plate 5 to cause a failure or a shortage of light amount due to surface contamination.
実施の形態１に係る栽培装置２０は、上記の植物栽培棚１１を複数段積み重ねて配置されているが、植物栽培棚１１を積み重ねずに一段だけ配置してもよい。
The cultivating apparatus 20 according to the first embodiment is arranged by stacking the above-described plant cultivation shelves 11 in a plurality of stages, but the plant cultivation shelves 11 may be arranged in one stage without being stacked.
