 しかしながら、上記の植物栽培システムでは、植物の植付姿勢に制約が生じるため、植物の種類(例えばキャベツ等)によっては、栽培が困難なものがあることが明らかとなっている。
 これに対して、栽培ベッドを上下複数段に設けてなる多段棚式の植物栽培システムが知られている。このような植物栽培システムであれば、植物の植付姿勢にも無理がないことから、植物の種類を問わず比較的効率よく生産をおこなうことができる。
However, in the above plant cultivation system, restrictions are imposed on the planting posture of plants, and it has become clear that some plants are difficult to grow depending on the type of plant (for example, cabbage).
On the other hand, a multistage shelf type plant cultivation system in which cultivation beds are provided in a plurality of upper and lower stages is known. If it is such a plant cultivation system, since there is no unreasonableness also in the planting attitude | position of a plant, it can produce comparatively efficiently irrespective of the kind of plant.

A quantity of artificial light that is favorable for growth can always be irradiated. Thereby, the growth of the cultivated plant is promoted.
 また、空調装置により、各栽培ベッドの一方側から他方側に向かって形成される空気通路に、温度、湿度、CO濃度等が調整された空気を順次送り込むことにより、人工光源から発せられる熱を取り除き、栽培植物の周囲の温度や湿度等を、生育に最も適した状態にすることができる。さらに、空調装置を、筒状の形状とし、該栽培ベッドの長辺側に沿って一方に近接して、上下に移動可能な該天井部に固着して設置することで、天井部の昇降動作に連動して昇降し、天井部がどのような位置にあっても、常に天井部の真下部分に低温の空気を吹き付けることが可能となり、人工光源から発せられる熱をより確実に除去することができる。 Moreover, the heat generated from the artificial light source by sequentially sending air with adjusted temperature, humidity, CO 2 concentration, etc., into the air passage formed from one side to the other side of each cultivation bed by the air conditioner. The temperature and humidity around the cultivated plant can be brought into a state most suitable for growth. Furthermore, the air conditioner has a cylindrical shape, and is installed in close proximity to one side along the long side of the cultivation bed and fixed to the ceiling part that can be moved up and down, thereby raising and lowering the ceiling part. It is possible to blow low temperature air to the part directly below the ceiling part regardless of the position of the ceiling part, and more reliably remove the heat emitted from the artificial light source. it can.

 図3に示すように、植物栽培システム2では、供給タンク44に貯留される養液Aが、供給ポンプP1によってポンプアップされ、給液管41を介して各栽培ベッド40に供給される。養液Aとしては、液肥を希釈したものが用いられる。
 各栽培ベッド40から排出された養液Aは、排液管42を介して、土間地下に埋設されるポンプ槽50に収集されたのち、汲み上げポンプP2によってポンプアップされ、戻り液タンク45に回収される。ポンプ槽50と戻り液タンク45との間には、ゴミ取りカゴ52が介設されており、ここで汚泥等の大きなゴミが取り除かれる。
As shown in FIG. 3, in the plant cultivation system 2, the nutrient solution A stored in the supply tank 44 is pumped up by the supply pump P <b> 1 and supplied to each cultivation bed 40 via the liquid supply pipe 41. As the nutrient solution A, a solution obtained by diluting liquid fertilizer is used.
The nutrient solution A discharged from each cultivation bed 40 is collected in the pump tank 50 embedded in the soil underground via the drainage pipe 42, then pumped up by the pumping pump P2 and collected in the return liquid tank 45. Is done. A dust removal basket 52 is interposed between the pump tank 50 and the return liquid tank 45, where large dust such as sludge is removed.
 戻り液タンク45に運ばれた養液Aは、戻り液ポンプP3によってポンプアップされ、ろ過装置47および殺菌装置48を通過して、再び供給タンク44に貯留される。ろ過装置47は、フィルター54によって形成されており、ここで小さなゴミまで取り除くことができる。殺菌装置48は、オゾン発生器55を備えており、オゾン発生器55によって発生させたオゾンを、戻り液タンク45から供給タンク44に移される養液Aに混入攪拌して殺菌処理する機能を有している。 The nutrient solution A carried to the return liquid tank 45 is pumped up by the return liquid pump P3, passes through the filtration device 47 and the sterilization device 48, and is stored again in the supply tank 44. The filtration device 47 is formed by the filter 54, and even small dust can be removed here. The sterilizer 48 includes an ozone generator 55 and has a function of sterilizing the ozone generated by the ozone generator 55 by mixing and stirring the nutrient solution A transferred from the return liquid tank 45 to the supply tank 44. is doing.
 供給タンク44には、養液Aの濃度および容量を一定の値に保持する自動管理手段としての濃度センサー57および液位置センサー58が設けられている。図中60はコントローラであり、濃度センサー57および液位置センサー58からの入力信号に基づき、原液注入ポンプP4を適宜駆動させるようになっている。原液注入ポンプP4の駆動に伴って、原液タンク62の原液Bが供給タンク44に供給されるとともに、必要によって井水Wが混合攪拌されることにより、供給タンク44内で所定の養液Aが新たに調合される。 The supply tank 44 is provided with a concentration sensor 57 and a liquid position sensor 58 as automatic management means for maintaining the concentration and volume of the nutrient solution A at a constant value. In the figure, reference numeral 60 denotes a controller which appropriately drives the stock solution injection pump P4 based on input signals from the concentration sensor 57 and the liquid position sensor 58. As the stock solution injection pump P4 is driven, the stock solution B in the stock solution tank 62 is supplied to the supply tank 44, and if necessary, the well water W is mixed and stirred so that a predetermined nutrient solution A is supplied in the supply tank 44. Newly formulated.
 供給タンク44には、養液Aの温度を一定の値に保持する自動管理手段としての温度センサー59も設けられている。温度センサー59が検出した信号は同様にコントローラ60に入力され、循環ポンプP5を駆動させる。循環ポンプP5は、供給タンク44内の養液Aをポンプアップし、冷温装置65を介して適温とされた養液Aが、供給タンク44へと戻される。冷温装置65は、熱交換器66、冷温水槽67、冷温水ポンプP6、ヒートポンプチラー68とから構成されるものである。
 このようにして、供給タンク44に貯留される養液Aが、栽培植物Pの生育に最良のものとなるように常時保たれている。
The supply tank 44 is also provided with a temperature sensor 59 as automatic management means for maintaining the temperature of the nutrient solution A at a constant value. Similarly, the signal detected by the temperature sensor 59 is input to the controller 60 to drive the circulation pump P5. The circulation pump P <b> 5 pumps up the nutrient solution A in the supply tank 44, and the nutrient solution A having an appropriate temperature is returned to the supply tank 44 via the cooling / heating device 65.

 次に、栽培ベッド40及び植付パネル73について、図4、図5、図9、図10を参照してさらに説明する。図4は、育成室10の育成棚30に設けられる栽培ベッド40を示す一部破断拡大図、図5は溢流堰を設けた栽培ベッドを示す一部破断拡大図、図9は育苗用の植付パネルを示す図、図10は育成用の植付パネルを示す図である。 Next, the cultivation bed 40 and the planting panel 73 will be further described with reference to FIGS. 4, 5, 9, and 10. 4 is a partially broken enlarged view showing the cultivation bed 40 provided on the growing shelf 30 of the growing room 10, FIG. 5 is a partially broken enlarged view showing the cultivation bed provided with the overflow weir, and FIG. 9 is for raising seedlings. The figure which shows a planting panel, FIG. 10 is a figure which shows the planting panel for cultivation.
 図4に示すように、育成棚30が、直方体枠組み状に剛構成された架台70において、所定間隔で上下複数段に配設保持される栽培ベッド40を備えて構成されている。各栽培ベッド40は、ブラケットやアングルピース等の保持手段(図示せず)を介して、架台70の縦部材に略水平に固設されている。
 栽培ベッド40の段数は、植物の種類等によっても異なるが、3~9段程度とするのが作業性や生産効率の点から好ましい。
As shown in FIG. 4, the growing shelf 30 is configured to include a cultivation bed 40 that is arranged and held in a plurality of stages at predetermined intervals in a gantry 70 that is rigidly configured in a rectangular parallelepiped frame shape. Each cultivation bed 40 is fixed substantially horizontally to a vertical member of the gantry 70 via holding means (not shown) such as a bracket and an angle piece.
The number of stages of the cultivation bed 40 varies depending on the type of plant, but is preferably about 3 to 9 stages from the viewpoint of workability and production efficiency.
 栽培ベッド40は、平面視950mm×2600mmの矩形板状をなし、上部開放箱型の栽培槽72と、栽培槽72の上部に嵌着される植付パネル73とから構成されている。栽培槽72の底面75と植付パネル73との間には、養液Aの流路76が形成されている。そして、給液管41から分岐管41aを介して供給される養液Aが、植付パネル73の所定位置に穿設された給液口73aから栽培ベッド40に流入し、この流路76を連続的に通過して、栽培槽72の底面75の所定位置に接続される排液口75aおよび分岐管42aを介して、排液管42へと流下排出されるようになっている。 The cultivation bed 40 has a rectangular plate shape of 950 mm × 2600 mm in a plan view, and includes an upper open box type cultivation tank 72 and a planting panel 73 fitted on the upper part of the cultivation tank 72. A channel 76 for the nutrient solution A is formed between the bottom surface 75 of the cultivation tank 72 and the planting panel 73. Then, the nutrient solution A supplied from the liquid supply pipe 41 via the branch pipe 41 a flows into the cultivation bed 40 from the liquid supply port 73 a drilled at a predetermined position of the planting panel 73, and passes through this flow path 76. It passes continuously and flows down to the drainage pipe 42 through the drainage port 75a and the branch pipe 42a connected to a predetermined position on the bottom surface 75 of the cultivation tank 72.
 植付パネル73には、栽培植物Pを植付状態とするためのポット78を支持するポット受孔79が適宜の間隔で多数穿設されている。ポット78は、底部が開放且つ先端部がカットされた逆円錐形で、栽培植物Pの苗を培土とともに収容して栽培するための容器である。栽培植物Pは、植物根P’が、ポット78を貫通して、植付パネル73の下方に露出するようにして配設される。 The planting panel 73 has a large number of pot receiving holes 79 that support the pot 78 for planting the cultivated plant P at appropriate intervals. The pot 78 is an inverted conical shape whose bottom is open and whose tip is cut, and is a container for accommodating and cultivating seedlings of the cultivated plant P together with soil. The cultivated plant P is arranged such that the plant root P ′ penetrates the pot 78 and is exposed below the planting panel 73.
 また、種の状態から苗の状態になるまで栽培する育苗用と、苗の状態から収穫できる状態になるまで栽培する育成用との二種類の植付パネル73を用いると、より好ましい。育苗用植付パネル73aは、図9(a)(b)に示すとおり、表面にポット受孔79aを多数有する平板であり、四隅と、横辺の中間部に、平板を高い位置で地面から支えるための脚部77が設けられている。また、ポット受孔79aは、上下ともに開放された逆円錐台形となっている。育苗用植付パネルの高さは約5cmであり、ポット受孔の深さは約3cmであることから、育苗用植付パネルは、ポット受孔の下端が植付パネルの高さの略中間に位置するよう、ポット受孔を吊り下げた状態となっている。
 育成用植付パネル73bは、図10(a)(b)に示すとおり、育苗用植付パネル73aよりも、配置されるポット受孔の数が少なくなっている。その他の構成は、育苗用植付パネル73aと同様である。
Moreover, it is more preferable to use two types of planting panels 73 for growing seedlings that are cultivated from the seed state to a seedling state and for growing the seedlings until they are harvested from the seedling state. As shown in FIGS. 9A and 9B, the seedling planting panel 73a is a flat plate having a large number of pot receiving holes 79a on the surface, and the flat plate is located at a high position from the ground at the four corners and the middle part of the horizontal side. Legs 77 for supporting are provided. The pot receiving hole 79a has an inverted truncated cone shape that is open on both the upper and lower sides. The height of the seedling planting panel is about 5 cm and the depth of the pot receiving hole is about 3 cm. Therefore, the lower end of the pot receiving hole is about the middle of the height of the planting panel. The pot receiving hole is suspended so as to be positioned at the position.
As shown in FIGS. 10A and 10B, the growing planting panel 73b has fewer pot receiving holes than the seedling-growing planting panel 73a. The other structure is the same as that of the seedling planting panel 73a.
 育苗用植付パネル73aを用いる場合、ポット受孔79aに、栽培植物Pの種を植えた逆円錐形のウレタン等を培地として挿入する。そして、この育苗用植付パネルを栽培槽72に嵌着し、栽培する。流路76に養液Aを供給することにより、植付パネル73aの下部空間を養液Aが流れることになるが、ポット受孔79aの底部から1cm乃至1.5cm程度養液Aが浸る程度となることが好ましい。ポット受孔79aの底部は開放されているため、底部に1cm程度養液Aが浸ると、毛細管現象により、培地となるウレタン等の下部から上部まで短時間で養液Aが行き渡る。これにより、培地の上部に植え付けた栽培植物Pの種にも、十分に養分が行き渡ることとなる。また、流路76への養液Aの供給を停止し、養液Aをすべて排出した場合、ポット受孔79aの底部が植付パネル73aの底部よりも上位に設けられ、ポット受孔79aの底部が開放されていること、及び培地に水はけのよいウレタン等を用いることから、培地から、養液Aが短時間で排出される。このような構成により、栽培植物Pの種を植えた培地に養液Aを供給し、又は培地から養液Aを排出する作業を迅速に行うことが可能となる。
 上記育苗用植付パネル73aを用いて栽培植物Pを種の状態から育苗し、苗の状態になると、ポット受孔79aから培地を育成用植付パネル73bに植え替える。育苗用植付パネル73aと育成用植付パネル73bとは、ポット受孔の直径及び深さが略等しいため、培地はどちらにも容易に挿入できる。そして、育苗用植付パネル73aを栽培槽72から取り外し、該育成用植付パネル73bを栽培槽72に嵌着する。もちろん、あらかじめ植付パネルが嵌着されていない栽培槽を用意しておき、この栽培槽を用いてもよい。このように、二種類の植付パネルを用いることにより、苗の状態までは育苗用植付パネル73aを用いることで、より少ない植付パネル数で育成することができ、栽培に要される養液や照明を抑制できるため、経済的かつ効率よく栽培できる。また、育成用植付パネル73bは、ポット受孔間の配置間隔が広いため、育成用植付パネル73bへと移すことにより、栽培植物Pが苗の状態からさらに成長しても、互いに接触することなく、育成が阻害されることはない。
When using the planting panel 73a for raising seedlings, an inverted conical urethane or the like planted with seeds of the cultivated plant P is inserted into the pot receiving hole 79a as a medium. Then, the seedling planting panel is fitted into the cultivation tank 72 and cultivated. By supplying the nutrient solution A to the flow path 76, the nutrient solution A flows through the lower space of the planting panel 73a. However, the nutrient solution A is immersed by about 1 cm to 1.5 cm from the bottom of the pot receiving hole 79a. It is preferable that Since the bottom of the pot receiving hole 79a is open, when the nutrient solution A is immersed in the bottom by about 1 cm, the nutrient solution A spreads in a short time from the lower part to the upper part of urethane or the like serving as a medium due to capillary action. Thereby, nutrients will be sufficiently distributed to the seeds of the cultivated plant P planted on the top of the medium. Further, when the supply of the nutrient solution A to the flow path 76 is stopped and the nutrient solution A is completely discharged, the bottom portion of the pot receiving hole 79a is provided higher than the bottom portion of the planting panel 73a, and the pot receiving hole 79a The nutrient solution A is discharged from the culture medium in a short time because the bottom is open and the well-drained urethane is used for the culture medium. With such a configuration, it is possible to quickly perform the operation of supplying the nutrient solution A to the medium in which the seeds of the cultivated plant P are planted or discharging the nutrient solution A from the medium.
When the cultivated plant P is grown from the seed state using the seedling planting panel 73a, and the seedling state is reached, the medium is replanted from the pot receiving hole 79a to the planting panel 73b. Since the seedling planting panel 73a and the breeding planting panel 73b have substantially the same diameter and depth of the pot receiving holes, the medium can be easily inserted into either of them. Then, the seedling planting panel 73 a is removed from the cultivation tank 72, and the breeding planting panel 73 b is fitted into the cultivation tank 72. Of course, a cultivation tank not fitted with a planting panel may be prepared in advance, and this cultivation tank may be used. Thus, by using two types of planting panels, it is possible to grow with a smaller number of planting panels by using the seedling planting panel 73a up to the state of the seedling, and the cultivation required for cultivation. Since liquid and lighting can be suppressed, it can be cultivated economically and efficiently. Moreover, since the planting panel 73b for cultivation has a wide arrangement interval between pot receiving holes, even if the cultivated plant P further grows from the state of the seedling by moving to the planting panel 73b for cultivation, they contact each other. Without this, breeding is not hindered.
 排液口75aは、入口側よりも出口側が窄んだ漏斗状に形成されており、電磁弁41bによって養液Aの流入量や流入スピードを調整することで、流路76内を養液Aで略一杯に満たし、流路76に向けて露出した植物根P’が流路76を通過する養液Aに接触して、養液A中の栄養分を十分に吸収できるようになされている。 The drainage port 75a is formed in a funnel shape in which the outlet side is narrower than the inlet side. By adjusting the inflow amount and the inflow speed of the nutrient solution A by the electromagnetic valve 41b, the inside of the flow path 76 is fed with the nutrient solution A. The plant root P ′ that is filled almost completely and exposed to the flow path 76 comes into contact with the nutrient solution A passing through the channel 76 so that the nutrients in the nutrient solution A can be sufficiently absorbed.
 また、養液Aは、電磁弁41bを介して、流路76に間欠的に流入するように制御されている。養液Aの供給を一定時間ごとにストップし、植物根P’に養液Aと空気を交互に触れさせることで栽培植物Pの成長をさらに促進することができる。そのため、植付パネル73に空気を取り込むための多数の透孔を設けたり、植付パネル73自体をメッシュ状に形成すればより好ましい。 Further, the nutrient solution A is controlled to intermittently flow into the flow path 76 via the electromagnetic valve 41b. The supply of the nutrient solution A is stopped at regular intervals, and the growth of the cultivated plant P can be further promoted by alternately contacting the nutrient solution A and air with the plant root P ′. Therefore, it is more preferable if the planting panel 73 is provided with many through holes for taking in air, or the planting panel 73 itself is formed in a mesh shape.
 なお、栽培槽72における流路76の下流側に上部空間が開放された溢流堰91を形成し、養液Aが所定量になると堰を超えて、排液管42へと流出するような構成とすることもできる(図5)。この場合、溢流堰の下部に、排液用の小孔92を適所に設け、養液Aの供給を止めたときに、栽培槽72内の養液Aを残らず排液管へと排出できるようにする。また、溢流堰91の内側に、電磁弁に接続した排液口75aを設けておき、栽培槽72内の養液Aを残らず排液管42へと排出できるようにしてもよい。養液Aを排出し、植物根P’に空気を触れさせることで、植物根P’が刺激を受け、次に流入してくる養液Aを活発に吸い上げる。これによって、栽培植物Pの成長が促進される。
 また、植付パネル73を固定しておき、養液Aの満ちた栽培槽72を上下させる構成とすることもできる。
In addition, the overflow weir 91 having an open upper space is formed on the downstream side of the flow path 76 in the cultivation tank 72, and when the nutrient solution A reaches a predetermined amount, it flows over the weir and flows into the drainage pipe 42. It can also be configured (FIG. 5). In this case, when a small hole 92 for drainage is provided at an appropriate position below the overflow weir and the supply of the nutrient solution A is stopped, the nutrient solution A in the cultivation tank 72 does not remain and is discharged to the drainage pipe. It can be so. Moreover, the drainage port 75a connected to the solenoid valve may be provided inside the overflow weir 91 so that the nutrient solution A in the cultivation tank 72 does not remain and can be discharged to the drainage pipe 42. By discharging the nutrient solution A and allowing the plant root P ′ to be exposed to air, the plant root P ′ is stimulated and actively sucks in the nutrient solution A that flows next. Thereby, the growth of the cultivated plant P is promoted.
Moreover, the planting panel 73 can be fixed and the cultivation tank 72 filled with the nutrient solution A can be moved up and down.
 栽培植物Pとしては、野菜や果物など様々な種類の植物が対象となる。特に流路76内の養液Aが常に新鮮な状態に保たれることから、将来的には山葵や生姜も好適に採用され得る。 As the cultivated plant P, various types of plants such as vegetables and fruits are targeted. In particular, since the nutrient solution A in the flow path 76 is always kept fresh, yam or ginger can be suitably used in the future.
 図4に示すように、各栽培ベッド40の上方には、それぞれ栽培植物Pを照射するための人工光源80が付設されている。人工光源80は、手動または自動の走行装置81を介して、栽培ベッド40に対して上下移動自在に構成されている。
 人工光源80は、栽培植物Pの成長に応じて上下移動させられる。光の強度や量が不足すると栽培植物Pの成長が遅れ、逆に過剰であると栽培植物Pに焼け等が生じる結果となる。上記人工光源80の構成によれば、人工光源80と栽培植物Pとの間の距離が常に適正(通常10~20cm程度)に保たれ、栽培植物Pの成長を促進することが可能となる。
As shown in FIG. 4, an artificial light source 80 for irradiating each cultivated plant P is attached above each cultivation bed 40. The artificial light source 80 is configured to be movable up and down with respect to the cultivation bed 40 via a manual or automatic traveling device 81.
The artificial light source 80 is moved up and down as the cultivated plant P grows. If the intensity or amount of light is insufficient, the growth of the cultivated plant P is delayed. Conversely, if it is excessive, the cultivated plant P is burned. According to the configuration of the artificial light source 80, the distance between the artificial light source 80 and the cultivated plant P is always kept appropriate (usually about 10 to 20 cm), and the growth of the cultivated plant P can be promoted.
 さらに、図6(a)(b)に示すように、各栽培ベッド40の上方に天井部115を、天井部115の上方に駆動部118を設け、駆動部の作用により天井部を上下に移動可能としてもよい。天井部115は、栽培ベッド40に並行してその上部に設けられており、栽培ベッド40と同程度の面積を有する。駆動部118は、薄い箱型の形状で栽培ベッド40とは略水平に固着保持されており、主として軸ボルト100と、左右一対のアーム101a,101bとが内部に配置されている。
 軸ボルト100は、全長にわたって螺子が刻設されたものであり、図6(a)(b)に示すように、駆動部118の略中央位置に前後に延在して設けられている。アーム101a,101bは、図6(a)(b)に示すように、左右対称のくの字状に形成されており、従動部102a,102bを介してそれぞれ開閉自在となされている。アーム101a,101bの先端部には、螺合部104,104が、アーム101a,101bに対して回動自在に接続されている。そして、この螺合部104,104を介して、アーム101a,101bが平面視菱形状となるように、軸ボルト100に螺合されている。
Further, as shown in FIGS. 6A and 6B, a ceiling 115 is provided above each cultivation bed 40, and a driving unit 118 is provided above the ceiling 115, and the ceiling is moved up and down by the action of the driving unit. It may be possible. The ceiling part 115 is provided in the upper part in parallel with the cultivation bed 40, and has the same area as the cultivation bed 40. The drive unit 118 has a thin box shape and is fixed and held substantially horizontally with the cultivation bed 40, and a shaft bolt 100 and a pair of left and right arms 101a and 101b are mainly disposed inside.
The shaft bolt 100 is provided with a screw engraved over its entire length, and is provided so as to extend back and forth at a substantially central position of the drive unit 118 as shown in FIGS. 6 (a) and 6 (b). As shown in FIGS. 6 (a) and 6 (b), the arms 101a and 101b are formed in symmetrical left and right shapes, and can be opened and closed via the driven portions 102a and 102b, respectively. Screwed portions 104, 104 are rotatably connected to the tips of the arms 101a, 101b with respect to the arms 101a, 101b. The arms 101a and 101b are screwed to the shaft bolt 100 via the screw portions 104 and 104 so that the arms 101a and 101b have a rhombus shape in plan view.
 軸ボルト100の前端には、所定の操作孔106が露呈して連接されており、操作ハンドル109(図6(b))の先端を操作孔106に差し込むことによって、軸ボルト100を正逆廻りに容易に回転させることができる。
 上記螺合部104,104は、互いに逆向きの螺子が切られており、軸ボルト100の回転に伴って、螺合部104,104が、軸ボルト100に沿って互いに近づいたり離れたりして前後対称の移動をおこなう。これに従って、螺合部104,104に接続されるアーム101a,101bが左右方向に伸縮する。つまり、アーム101a,101bがそれぞれ開き角度を大小変化させながら、従動部102a,102bが軸ボルト100に略直行して互いに近づいたり離れたりして、左右対称の移動を行う。そして、天井部115の四隅近傍が、ワイヤー等の吊設部材110を介して従動部102a,102bに連結されていることから、従動部102a,102bの上記移動に連係して、天井部115が上下に移動可能となるものである。
A predetermined operation hole 106 is exposed and connected to the front end of the shaft bolt 100. By inserting the tip of the operation handle 109 (FIG. 6B) into the operation hole 106, the shaft bolt 100 is rotated in the forward and reverse directions. Can be easily rotated.
The threaded portions 104 and 104 are threaded in directions opposite to each other. As the shaft bolt 100 rotates, the threaded portions 104 and 104 move toward and away from each other along the shaft bolt 100. Perform symmetrical movement. Accordingly, the arms 101a and 101b connected to the screwing portions 104 and 104 expand and contract in the left-right direction. That is, while the arms 101a and 101b each change the opening angle, the driven portions 102a and 102b move substantially symmetrically to the shaft bolt 100 and move toward and away from each other, thereby performing a symmetrical movement. And since the four corner vicinity of the ceiling part 115 is connected with the driven parts 102a and 102b via the suspension members 110, such as a wire, the ceiling part 115 is linked with the said movement of the driven parts 102a and 102b. It can move up and down.
 また、図13(a)(b)に示すように、駆動部118は、主に軸ボルト100と、左右対となる各2個1組で配置されるの内側滑車107a,107b、及び外側滑車108a,108bとからなる構成としてもよい。
 軸ボルト100は全長にわたって螺子が刻設されたものであり、図13(a)(b)に示すように、駆動部118の略中央に前後して延在して設けられている。内側滑車107a,107bは、図13(a)(b)に示すように、螺合部104,104と線で結んだ場合に平面視菱形状となるよう、左右にそれぞれ、近接して2個ずつ駆動部118に固定して設けられている。外側滑車108a,108bは、図13(a)(b)に示すように、内側滑車107a,107bから軸ボルト100と垂直方向外側に、近接して2個ずつ駆動部118に固定して設けられている。
 そして、1つの螺合部104には左右に1本ずつワイヤー等の吊設部材70が着設されており、各吊設部材70は、内側滑車107a,107b及び外側滑車108a,108bを介して、それぞれ駆動部118の該螺合部側の四隅へと延伸される。もう一方の螺合部104からも同様に左右に1本ずつ吊設部材70が内側滑車107a,107b及び外側滑車108a,108bを介して四隅へと延伸される。そして、駆動部118の四隅には開口部が設けられており、それぞれの吊設部材70は該開口部を遊貫して、天井部115へと連結される。
Further, as shown in FIGS. 13A and 13B, the drive unit 118 is mainly composed of the shaft bolt 100 and the inner pulleys 107a and 107b and the outer pulleys that are arranged in a pair of left and right pairs. It is good also as a structure which consists of 108a, 108b.
The shaft bolt 100 has a screw engraved over its entire length, and is provided so as to extend back and forth substantially at the center of the drive unit 118 as shown in FIGS. 13 (a) and 13 (b). As shown in FIGS. 13 (a) and 13 (b), two inner pulleys 107a and 107b are arranged close to each other on the left and right sides so as to form a rhombus shape in plan view when connected to the threaded portions 104 and 104 by a line. They are fixed to the drive unit 118 one by one. As shown in FIGS. 13 (a) and 13 (b), the outer pulleys 108a and 108b are fixed to the driving unit 118 two by two in close proximity to the axial bolt 100 from the inner pulleys 107a and 107b. ing.
One threaded portion 104 is provided with a suspension member 70 such as a wire on the left and right, and each suspension member 70 is connected to the inner pulleys 107a and 107b and the outer pulleys 108a and 108b. , Respectively, are extended to the four corners of the driving portion 118 on the screwing portion side. Similarly, from the other threaded portion 104, one hanging member 70 is extended to the four corners via the inner pulleys 107a and 107b and the outer pulleys 108a and 108b. And the opening part is provided in the four corners of the drive part 118, and each suspending member 70 penetrates this opening part, and is connected with the ceiling part 115. As shown in FIG.
 軸ボルト100の前端には、所定の操作孔106が露呈して連接されており、操作ハンドル109の先端を操作孔106に差し込むことによって、軸ボルト100を正逆廻りに容易に回転させることができる。
 上記螺合部104,104は、互いに逆向きの螺子が切られており、軸ボルト100の回転に伴って、螺合部104,104が、軸ボルト100に沿って互いに近づいたり離れたりして前後対称の移動をおこなう。これに従って、螺合部104,104から内側滑車107a,107bまでの吊設部材70の距離が長短に変化する。つまり、螺合部が軸ボルト上中央に近づけば近づくほど内側滑車との距離は短くなるし、逆に離れれば離れるほど内側滑車との距離は長くなる。各吊設部材70自体の長さは変化しないため、螺合部104,104の近づいたり離れたりする前後対称の移動に連係して、螺合部104,104から内側滑車107a,107bまでの吊設部材70の長さが長短変動し、よって、天井部115が上下に移動可能となるものである。
 上記構成により、人工光源80と栽培植物Pとの間の距離を常に栽培植物Pの成育に最も適した距離に保つことが可能となる。
A predetermined operation hole 106 is exposed and connected to the front end of the shaft bolt 100. By inserting the tip of the operation handle 109 into the operation hole 106, the shaft bolt 100 can be easily rotated in the forward and reverse directions. it can.
The threaded portions 104 and 104 are threaded in directions opposite to each other. As the shaft bolt 100 rotates, the threaded portions 104 and 104 move toward and away from each other along the shaft bolt 100. Perform symmetrical movement. Accordingly, the distance of the suspending member 70 from the screwing portions 104, 104 to the inner pulleys 107a, 107b changes in length. That is, the closer to the center on the shaft bolt, the shorter the distance from the inner pulley, and vice versa. Since the length of each suspension member 70 itself does not change, the suspension from the threaded portions 104 and 104 to the inner pulleys 107a and 107b is linked to the symmetrical movement of the threaded portions 104 and 104 approaching and leaving. The length of the installation member 70 fluctuates in length, and thus the ceiling 115 can be moved up and down.
By the said structure, it becomes possible to always keep the distance between the artificial light source 80 and the cultivated plant P at the most suitable distance for the growth of the cultivated plant P.
 上記のような駆動部118を用いれば、アーム61a,61b、あるいは吊設部材70が、軸ボルト60を含む略同一平面内で伸縮して天井部115を上下移動させるため、天井部115上方の懐空間を非常に薄く構成することが可能となる。また、操作ハンドル109による簡単な操作であり、微調整も容易であることから、誤って栽培植物Pを傷つけてしまうおそれが低い。 When the driving unit 118 as described above is used, the arms 61a and 61b or the suspending member 70 expand and contract in substantially the same plane including the shaft bolt 60 to move the ceiling unit 115 up and down. It is possible to make the pocket space very thin. Moreover, since it is a simple operation by the operation handle 109 and fine adjustment is easy, there is a low risk of damaging the cultivated plant P by mistake.
 人工光源80としては、栽培植物Pの成長にとって好ましい波長域となるように、蛍光灯、高圧ナトリウムランプ、水銀ランプ、メタルハライドランプ、冷陰極ランプ、LED等を単独でまたは複数組み合わせて用いることができる。LEDを用いる場合には、例えば植付パネル73と略同面積の天井板を走行装置81によって上下移動自在に設け、この天井板に適宜間隔でLEDを埋設するようにしてもよい。 As the artificial light source 80, a fluorescent lamp, a high-pressure sodium lamp, a mercury lamp, a metal halide lamp, a cold cathode lamp, an LED, or the like can be used alone or in combination so that the wavelength range is preferable for the growth of the cultivated plant P. . When using the LED, for example, a ceiling plate having substantially the same area as the planting panel 73 may be provided so as to be movable up and down by the traveling device 81, and the LED may be embedded in the ceiling plate at an appropriate interval.
 また、図4に示すように、各栽培ベッド40は、空調装置84を備えている。空調装置84では、栽培ベッド40の短辺上部の一方側に送風口85、他方側に排気ファン86が設けられており、栽培ベッド40の上方において一方側から他方側に循環する空気通路87が形成されている。送風口85は、上記空調機34から延出するダクト34aの吹出し口に適宜接続されるとともに、排気ファン86は、上記空調機35から延出するダクト35aの吸込み口に適宜接続されている(図2参照)。送風口85に替えて、送風ファンを設けるようにしてもよい。 Moreover, as shown in FIG. 4, each cultivation bed 40 includes an air conditioner 84. In the air conditioner 84, an air outlet 85 is provided on one side of the upper short side of the cultivation bed 40 and an exhaust fan 86 is provided on the other side, and an air passage 87 that circulates from one side to the other side above the cultivation bed 40. Is formed. The air outlet 85 is appropriately connected to the outlet of the duct 34a extending from the air conditioner 34, and the exhaust fan 86 is appropriately connected to the inlet of the duct 35a extending from the air conditioner 35 ( (See FIG. 2). A blower fan may be provided in place of the blower opening 85.
 このような空調装置84により、温度、湿度、CO濃度等が調整された空気を、各栽培ベッド40の栽培植物Pに確実に供給することが可能となる。空調効果を高めるために、育成棚30の架台70を断熱パネル等によって被覆する構成としてもよい。 By such an air conditioner 84, it is possible to reliably supply the air whose temperature, humidity, CO 2 concentration, and the like are adjusted to the cultivated plants P of each cultivation bed 40. In order to enhance the air conditioning effect, the frame 70 of the growing shelf 30 may be covered with a heat insulating panel or the like.
 また、空調装置84は、人工光源80の熱を除去する働きもなす。人工光源80には、上記した如く栽培植物Pの成長に応じて上下動し、栽培植物Pに対する距離を調節できる走行装置81が付設されている。上記送風口85や排気ファン86を、この走行装置81の動作に伴って上下動するように構成し、常に人工光源80近辺に向かって冷風を吹き付けて冷却するようにしてもよい。これにより、人工光源80付近に熱が滞り、栽培植物Pの成長に悪影響が生じるのを確実に防止することが可能となる。送風口85に替えて送風ファンを用いてもよいことは上述のとおりである。
 冷却後の空気は、育成室10内に拡散させ、育成室10の空気と混同させて空調機で冷やし、これを循環させるようにしてもよい。
The air conditioner 84 also serves to remove heat from the artificial light source 80. As described above, the artificial light source 80 is provided with a traveling device 81 that moves up and down according to the growth of the cultivated plant P and can adjust the distance to the cultivated plant P. The air blowing port 85 and the exhaust fan 86 may be configured to move up and down in accordance with the operation of the traveling device 81, and may be cooled by always blowing cool air toward the vicinity of the artificial light source 80. This makes it possible to reliably prevent heat from stagnating near the artificial light source 80 and adversely affecting the growth of the cultivated plant P. As described above, a blower fan may be used instead of the blower opening 85.
The cooled air may be diffused into the growth chamber 10, mixed with the air in the growth chamber 10, cooled by an air conditioner, and circulated.
 以上、説明した如くの植物栽培プラント1および植物栽培システム2によれば、栽培ベッド40の流路76に供給される養液Aが、流路76を連続的に通過して排出され、ろ過装置47や殺菌装置48、さらに自動管理手段を有する供給タンク44などを経由した後に循環して再利用されるものであるため、常に一定の新鮮な養液Aを栽培植物Pに供給することができ、栽培槽72の流路76内に雑菌等が繁殖するおそれが低い。また、人工光源80や空調装置84などの所定構成とも相俟って、栽培植物Pの成長を促進して効率良く栽培をおこなうことができるものである。 As described above, according to the plant cultivation plant 1 and the plant cultivation system 2 as described above, the nutrient solution A supplied to the flow path 76 of the cultivation bed 40 is continuously discharged through the flow path 76 and is filtered. 47, the sterilizer 48, and the supply tank 44 having automatic management means, etc., so that it can be circulated and reused, so that a constant fresh nutrient solution A can always be supplied to the cultivated plant P. There is a low risk that germs and the like will propagate in the flow path 76 of the cultivation tank 72. Further, in combination with predetermined configurations such as the artificial light source 80 and the air conditioner 84, the growth of the cultivated plant P can be promoted and cultivation can be performed efficiently.
 本発明の第2の実施例について、図面を参照しつつ説明する。第2の実施例は、実施例1における空調装置とは別構成の空調装置を用いるものである。図7は、実施例2に係る空調装置を備えた栽培ベッドを示す一部破断拡大図であり、図8は、実施例2に係る空調装置を備えた栽培ベッドを示す側面断面図である。
 図7、図8に示すとおり、第2の実施例に係る空調装置116の形状は、栽培ベッド40の長辺の長さに略相当する全長を有する筒状であり、天井の一方の長辺側に沿って近接して設けることを特徴とする。
 空調装置116は、上下方向に移動可能な天井部115に吊り下げて設け、天井部の昇降動作に連動して空調装置116も昇降することとする。固着手段としては、例えば、図8に示すとおり、バンド状の取付金具133を用いることが考えられる。空調装置116は、伸縮自在のフレキシブルダクト131および分岐ダクト132を介して、架台70に近接して設けられた空調装置用ダクト130に接続されている。空調装置用ダクト130は、上記空調機34から延出するダクト34aの吹出し口に接続されることとしてもよいし、別の空気発生源から空気を取り込むこととしてもよい。
 空調装置116のやや上部所定の位置には、多数の噴出口135a,135bが、千鳥状の上下二段に設けられている。そして、下側の噴出口135aから、栽培ベッド40に植え付けられている栽培植物Pに向けて、温度、湿度、CO濃度等が調整された空気が噴出される。
A second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, an air conditioner having a configuration different from that of the air conditioner in the first embodiment is used. FIG. 7 is a partially broken enlarged view showing the cultivation bed provided with the air conditioner according to the second embodiment. FIG. 8 is a side sectional view showing the cultivation bed equipped with the air conditioning apparatus according to the second embodiment.
As shown in FIGS. 7 and 8, the shape of the air conditioner 116 according to the second embodiment is a cylindrical shape having a total length substantially corresponding to the length of the long side of the cultivation bed 40, and one long side of the ceiling Providing close proximity along the side.
The air conditioner 116 is provided suspended from a ceiling 115 that is movable in the vertical direction, and the air conditioner 116 is also raised and lowered in conjunction with the raising and lowering operation of the ceiling. As the fixing means, for example, it is conceivable to use a band-shaped mounting bracket 133 as shown in FIG. The air conditioner 116 is connected to an air conditioner duct 130 provided in the vicinity of the gantry 70 via an elastic flexible duct 131 and a branch duct 132. The air conditioner duct 130 may be connected to the outlet of the duct 34a extending from the air conditioner 34 or may take air from another air generation source.
At a predetermined position slightly above the air conditioner 116, a large number of jet outlets 135a and 135b are provided in two staggered upper and lower stages. Then, from the lower side of the ejection port 135a, toward the cultivated plants P are planted in the cultivation bed 40, the temperature, humidity, CO 2 air density and the like are adjusted is ejected.
 また、図8に示すように、上側の噴出口135bからは、人工光源80に向けても、温度、湿度、CO濃度等が調整された空気が噴出される。これにより、人工光源80から生じた熱を取り除き、栽培ベッド40の上部空間の温度を低温に保つことが可能となる。植物の種類によっても異なるが、栽培植物Pが生育する上で理想となる温度は、およそ15℃から20℃である。一方、人工光源80と栽培植物Pとの距離は約10cm~20cmと短く、かつ、人工光源80近辺は約60℃と高温になるため、熱を除去する工夫がなければ、栽培植物Pの周辺は高温になってしまう。さらに、本発明の栽培ベッド40は上下複数段で構成されており、下段の人工光源80から発生した熱は上昇するため、上段の栽培ベッド40の周囲は、より高温になってしまう。仮に栽培ベッドが5段で構成される場合、最下段と最上段の栽培ベッド40周囲の温度を比較した場合、最上段のほうが、およそ10℃近くも高温となる。
 天井部115の昇降動作に連動して空調装置116も昇降する構成とすると、天井部115の上下位置に関係なく、いつでも上側の噴出口135bからは、人工光源80に向けて、15℃前後の低温の空気が噴出される。これにより、人工光源80付近あるいは真下に停滞する熱を拡散させ、人工光源80自体も冷却することで、栽培ベッドの周囲(特に上部空間)の温度の上昇をより確実に抑制し、栽培植物Pの生育に悪影響が生じるのを防止することができるのである。
Also, as shown in FIG. 8, air with adjusted temperature, humidity, CO 2 concentration and the like is ejected from the upper ejection port 135b toward the artificial light source 80 as well. Thereby, the heat generated from the artificial light source 80 can be removed, and the temperature of the upper space of the cultivation bed 40 can be kept low. Although it varies depending on the type of plant, the ideal temperature for growing the cultivated plant P is approximately 15 ° C. to 20 ° C. On the other hand, the distance between the artificial light source 80 and the cultivated plant P is as short as about 10 cm to 20 cm, and the vicinity of the artificial light source 80 is as high as about 60 ° C. Becomes hot. Furthermore, since the cultivation bed 40 of the present invention is composed of a plurality of upper and lower stages, and the heat generated from the lower artificial light source 80 rises, the periphery of the upper cultivation bed 40 becomes higher in temperature. If the cultivation bed is composed of five stages, when the temperature around the cultivation bed 40 at the lowermost stage and the uppermost cultivation bed 40 is compared, the uppermost stage is as high as about 10 ° C.
If the air conditioner 116 is also raised and lowered in conjunction with the raising and lowering operation of the ceiling 115, the upper jet port 135 b is always at about 15 ° C. toward the artificial light source 80 regardless of the vertical position of the ceiling 115. Cold air is ejected. Thereby, the heat stagnating near or directly below the artificial light source 80 is diffused, and the artificial light source 80 itself is also cooled, so that the increase in the temperature around the cultivation bed (particularly the upper space) can be more reliably suppressed. It is possible to prevent an adverse effect on the growth of the plant.
 なお、栽培ベッド40の上部空間の温度等を計測するセンサーを、各段ごとに設けてもよい。育成ベッド40は、下段の育成光源80の熱が上昇し加わることにより、上段ほど高温になる傾向にある。そこで、各段の栽培ベッド40ごとに温度を計測し、高温の段ほど多量の空気あるいは冷たい空気が噴出されるようにすると、各段の栽培ベッド40周囲の温度を一定に保つことが可能となる。また、噴出口135a,135bとしてノズルを用いる場合には、噴出される空気を分散させ易くなり、噴出口135a,135bの配設数を低減できる。 In addition, you may provide the sensor which measures the temperature etc. of the upper space of the cultivation bed 40 for every step. The growth bed 40 tends to become higher in temperature as the upper stage is heated by the heat of the lower stage growth light source 80 being increased. Therefore, if the temperature is measured for each stage of the cultivation bed 40 and a larger amount of air or cold air is ejected as the stage becomes higher, the temperature around the cultivation bed 40 of each stage can be kept constant. Become. Further, when nozzles are used as the jet outlets 135a and 135b, the jetted air can be easily dispersed, and the number of the jet outlets 135a and 135b can be reduced.
 また、天井部115の下面には、図8に示すように、傾斜壁面122、122を有する凹部123が、栽培ベッド40に略等しい左右幅で、且つ長辺に略並行して2列に形成されることとしてもよい。そして、この凹部123に、人工光源80が配設されるとともに、少なくとも上記傾斜壁面122が、反射性を有する材料によって形成されることとしてもよい。傾斜壁面122の傾斜角度は、人工光源80の光を反射させたい方向に応じて適宜設定し得るものであるが、おおむね30度から45度前後が好ましい。このような構成により、狭小な空間であっても、人工光源80による光を拡散させることなく、非常に効率よく集中的に栽培植物Pに与えることが可能となる。例えば人工光源80として蛍光灯を使用する場合には、光量が約1.3倍から1.4倍に増加する。しかも、上記天井部115の構造によれば、凹部123内の熱が、工夫した空調装置により冷却されることで逃げ易いため、空調負荷の低減にもなる。 Moreover, as shown in FIG. 8, the recessed part 123 which has the inclined wall surfaces 122 and 122 is formed in two rows on the lower surface of the ceiling part 115 in substantially parallel with the long side in the left-right width substantially equal to the cultivation bed 40. It may be done. And the artificial light source 80 is arrange | positioned in this recessed part 123, and the said inclined wall surface 122 is good also as being formed with the material which has reflectivity. The inclination angle of the inclined wall surface 122 can be appropriately set according to the direction in which the light from the artificial light source 80 is desired to be reflected, but is preferably approximately 30 to 45 degrees. With such a configuration, even in a narrow space, the light from the artificial light source 80 can be distributed to the cultivated plant P very efficiently without being diffused. For example, when a fluorescent lamp is used as the artificial light source 80, the amount of light increases from about 1.3 times to 1.4 times. In addition, according to the structure of the ceiling 115, the heat in the recess 123 is easily escaped by being cooled by the devised air conditioner, so that the air conditioning load is also reduced.
 本発明の第3の実施例について図面を参照しつつ説明する。第3の実施例は、植物栽培プラント1及び植物栽培システム2の全体監視及び全体操作に関するものであり、さらには、遠隔からの全体監視及び全体操作に関するものである。図11はモニターに表示されるシステムの監視画面であり、図12Aから図12Hは、モニター操作を行った際にモニターに表示される所定の画面であり、図19はシステムの全体監視操作に係るコンピュータの構成を示すブロック図であり、図20はシステムの所定の遠隔操作手順を示すフローチャートである。
 本発明の植物栽培プラント1及び植物栽培システム2は、すべて機械室12に設置されているコンピュータによって制御されており、管理室15あるいはその近辺に設置される小型モニターによって、全体監視及び全体操作が可能になっている。図19に示すように、該コンピュータは、主に、自動モードと手動モードとの切り替えや、手動モードにおける各種弁の開閉、流入させる養液の量や温度、照明の量などの植物の栽培に関係するデータを入力するための入力装置301、入力されたデータを処理し、実行するためのCPU等からなるデータ処理装置302、現状選択され入力されている植物の栽培に関係するデータや、育成する野菜の種類ごとに最も適した養液の量や温度、照明の量等の環境データを記憶するためのデータ記憶装置303、そして各種弁の開閉、養液の量や温度、室内外の温度や湿度等の、稼動している植物栽培システムの状況を表示するための表示装置304から構成される。本実施例では、入力装置301、および表示装置304に、タッチパネル式の小型モニターを採用している。
 小型モニターには、通常、図1のようにシステム全体を監視する「全体監視画面」が表示されている。この画面では、主に、各段の栽培ベッド40の温度、供給タンク44の温度等、戻り液タンク45の温度、養液のヒートポンプチラー68通過前後の温度、室内外の温度や湿度等、植物栽培システム2を稼動させる上で重要な情報を確認することができる。
 また、小型モニターは、タッチパネル式となっており、画面に触れることで、各種のシステム操作が可能となる。例えば、植物栽培システムは自動モードと手動モードとの切り替えが可能であり、通常は自動モードにしておくことで、植物栽培プラント1における植物の栽培に最も適した環境が維持されることとなる。また、各段の栽培ベッドごとに異なる植物を栽培するため、各段ごとに異なる温度・湿度設定にしたい場合や、なんらかの事情により自動モードでは植物の栽培に支障が生じる場合は、手動モードにすることにより、不都合な部分のシステム操作を個別に行うことが可能となる。
A third embodiment of the present invention will be described with reference to the drawings. The third embodiment relates to overall monitoring and overall operation of the plant cultivation plant 1 and the plant cultivation system 2, and further relates to remote overall monitoring and overall operation. 11 is a system monitoring screen displayed on the monitor, FIGS. 12A to 12H are predetermined screens displayed on the monitor when the monitor operation is performed, and FIG. 19 relates to the overall monitoring operation of the system. FIG. 20 is a block diagram showing a configuration of a computer, and FIG. 20 is a flowchart showing a predetermined remote operation procedure of the system.
The plant cultivation plant 1 and the plant cultivation system 2 of the present invention are all controlled by a computer installed in the machine room 12, and the overall monitoring and overall operation are performed by a small monitor installed in the management room 15 or in the vicinity thereof. It is possible. As shown in FIG. 19, the computer is mainly used for cultivation of plants such as switching between automatic mode and manual mode, opening and closing various valves in manual mode, amount of nutrient solution to be introduced, temperature, amount of illumination, etc. An input device 301 for inputting related data, a data processing device 302 including a CPU for processing and executing the input data, data related to cultivation of plants currently selected and input, and breeding Data storage device 303 for storing environmental data such as the amount and temperature of the nutrient solution most suitable for each type of vegetable to be used, the amount of lighting, etc., and the opening and closing of various valves, the amount and temperature of the nutrient solution, and the outdoor temperature And a display device 304 for displaying the status of the plant cultivation system in operation, such as humidity and humidity. In this embodiment, a touch panel type small monitor is employed for the input device 301 and the display device 304.
A small monitor normally displays an “overall monitoring screen” for monitoring the entire system as shown in FIG. In this screen, mainly the temperature of the cultivation bed 40 at each stage, the temperature of the supply tank 44, the temperature of the return liquid tank 45, the temperature of the nutrient solution before and after passing through the heat pump chiller 68, the indoor and outdoor temperature and humidity, etc. Important information for operating the cultivation system 2 can be confirmed.
The small monitor is a touch panel type, and various system operations are possible by touching the screen. For example, the plant cultivation system can be switched between an automatic mode and a manual mode, and the environment most suitable for the cultivation of plants in the plant cultivation plant 1 is maintained by normally setting the automatic mode. Also, because different plants are cultivated for each cultivated bed, if you want to set different temperature and humidity settings for each tier, or if there is a problem in cultivating plants in automatic mode for some reason, switch to manual mode. As a result, it is possible to individually perform inconvenient system operations.
 さらに、あらかじめ育成する植物の種類ごとに最も適した養液量や照明の量、あるいは空調装置から噴出される空気の温度や湿度等の各設定をコンピュータのデータ記憶装置303に記憶させておき、特定の設定データを読み出すことで、あらかじめ記憶させた各設定を選択的に再現することができる。そして自動モードにしておくと、人間がシステムを操作しなくとも、あらかじめ記憶させた設定データのとおりに植物栽培システムを構成する機器や装置が自動制御され、選択した設定が維持されることとなる。これにより、栽培する植物に適した設定データを選択し、あとは自動モードにしておくだけで、その植物に適した環境が人の手を介さずとも維持されるのである。 Furthermore, the most suitable amount of nutrient solution and amount of illumination for each type of plant to be cultivated in advance, each setting such as temperature and humidity of air blown from the air conditioner is stored in the data storage device 303 of the computer, By reading specific setting data, each setting stored in advance can be selectively reproduced. And if it is set as automatic mode, even if a human does not operate a system, the apparatus and apparatus which comprise a plant cultivation system will be automatically controlled as the setting data memorize | stored beforehand, and the selected setting will be maintained. . Thereby, setting data suitable for the plant to be cultivated is selected, and then the automatic mode is set, so that an environment suitable for the plant is maintained without human intervention.
 以下、小型モニターを用いた植物栽培システム2の操作方法の一例を、図11、図12A~図12C、図12F、及び図20を用いて説明する。ここでは、所定の栽培ベッド40への養液の供給あるいは停止を手動で行うこととする。まず、現在モニターに表示されている画面が、「全体監視画面」(図11)か否かを確認する(S1)。「全体監視画面」でなければ、「メインメニュー画面」(図12A)か否かを確認する(S2,S3)。「メインメニュー画面」であれば、選択ボタンの中から「監視画面」ボタンを選択し、入力する(S4,S5)。入力は、画面の上から指で触れることにより、容易に行われる。「メインメニュー画面」でなければ、画面下側の各種パネルボタンから、「監視」ボタンを選択し、入力する(S4,S6)。これにより、「監視メニュー」画面(図12F)が表示される(S7)。続いて、「監視メニュー」画面において、「全体監視画面1」ボタンを選択し、入力する(S8)。これにより、「全体監視画面」(図11)が表示される(S9)。
 次に、「全体監視画面」において、育成トレー1の弁の開閉状態を確認する(S10)。もし弁が閉じた状態であれば、現状のモードを確認する(S11,S12)。もし「自動モード」が選択されているならば、「手動モード」ボタンを選択し、入力する(S13,S14)。これにより、植物栽培システムを手動で制御できるようになり、育成トレー1の弁の開閉に関しても、手動で決定できるようになる(S15)。
 さらに、「全体監視画面」(図11)において、下側の各種パネルボタンから「メインメニュー」ボタンを選択し入力することで、「メインメニュー画面」(図12A)が表示される(S16,S17)。続いて、各システムを操作する場合は、「メインメニュー画面」において、「運転操作画面」のボタンを選択し入力することで、「運転操作メニュー」画面(図12B)が表示される(S18,S19)。続いて、「弁手動操作(トレー1)」ボタン選択し入力することで、「手動操作(育成1トレー用弁)」画面(図12C)が表示される(S20,S21)。そして、この画面上で、所定の栽培ベッドに養液Aを供給あるいは停止するための電磁弁の開閉が可能となり、弁を開きたい箇所の「開」ボタンを選択し入力することで目的が達成される(S22、S23)。
 電磁弁の開閉は、栽培ベッド各段ごとに可能であるため、1段目は養液Aを供給して、2段目は供給を停止する、といった制御も行える。なお、各種画面の下側の各種パネルボタンから「メインメニュー」ボタンを押すことで、「メインメニュー画面」に戻る。
Hereinafter, an example of an operation method of the plant cultivation system 2 using a small monitor will be described with reference to FIGS. 11, 12A to 12C, FIG. 12F, and FIG. Here, supply or stop of the nutrient solution to the predetermined cultivation bed 40 is performed manually. First, it is confirmed whether or not the screen currently displayed on the monitor is an “overall monitoring screen” (FIG. 11) (S1). If it is not the “entire monitoring screen”, it is checked whether it is a “main menu screen” (FIG. 12A) (S2, S3). If it is the “main menu screen”, the “monitoring screen” button is selected from the selection buttons and input (S4, S5). Input is easily performed by touching the screen with a finger. If it is not the “main menu screen”, the “monitor” button is selected from various panel buttons at the bottom of the screen and input (S4, S6). Thereby, the “monitoring menu” screen (FIG. 12F) is displayed (S7). Subsequently, the “overall monitoring screen 1” button is selected and input on the “monitoring menu” screen (S8). Thereby, the “overall monitoring screen” (FIG. 11) is displayed (S9).
Next, on the “overall monitoring screen”, the open / close state of the valve of the growth tray 1 is confirmed (S10). If the valve is closed, the current mode is confirmed (S11, S12). If "automatic mode" is selected, the "manual mode" button is selected and entered (S13, S14). Thereby, it becomes possible to manually control the plant cultivation system, and it is possible to manually determine the opening and closing of the valves of the growth tray 1 (S15).
Furthermore, in the “overall monitoring screen” (FIG. 11), the “main menu screen” (FIG. 12A) is displayed by selecting and inputting the “main menu” button from the various lower panel buttons (S16, S17). ).

 本発明の第4の実施例について、図面を参照しつつ説明する。第4の実施例は、家庭用の植物栽培装置を提供することを目的とするものである。図14、図15は第4の実施例に係る植物栽培装置201を示す図であり、図14は斜視図、図15は全体構成を示す概略図である。図16は植物栽培装置201の栽培ベッド210を示す図、図17、図18は植物栽培装置201の天井部215および空調装置216を示す図である。 A fourth embodiment of the present invention will be described with reference to the drawings. The fourth embodiment is intended to provide a household plant cultivation apparatus. 14 and 15 are views showing a plant cultivation apparatus 201 according to the fourth embodiment, FIG. 14 is a perspective view, and FIG. 15 is a schematic view showing an overall configuration. FIG. 16 is a diagram illustrating the cultivation bed 210 of the plant cultivation apparatus 201, and FIGS. 17 and 18 are diagrams illustrating the ceiling portion 215 and the air conditioner 216 of the plant cultivation apparatus 201.
 図14、図15に示すように、植物栽培装置201は、全体として直方体形状(左右950mm×奥行き600mm×高さ2100mm程度)で移設可能な箱体202をなし、この箱体202の内部に所要設備が格納されているものである。必要な電源は、家庭用電源200V等が利用される。
 箱体202は、図14に示すように、断熱パネル203で被覆されており、前面の大半に、開閉扉204が大きく設けられている。開閉扉204には、箱体202内部の栽培ベッド210(後述)に植え付けられる栽培植物Pを見通せる複層ガラス205が嵌装されている。このような構成により、熱負荷の軽減が図られて、効率的な生産が可能となる。また、栽培植物Pの成長状況等を容易に確認でき、楽しみながら栽培をおこなうことが可能となっている。
As shown in FIGS. 14 and 15, the plant cultivation apparatus 201 has a box 202 that can be moved as a whole in a rectangular parallelepiped shape (left and right 950 mm × depth 600 mm × height 2100 mm), and required inside the box 202. Equipment is stored. As a necessary power source, a household power source 200V or the like is used.
As shown in FIG. 14, the box 202 is covered with a heat insulating panel 203, and a large opening / closing door 204 is provided on most of the front surface. The open / close door 204 is fitted with a multi-layer glass 205 through which a cultivated plant P to be planted on a cultivation bed 210 (described later) inside the box 202 can be seen. With such a configuration, the thermal load can be reduced and efficient production becomes possible. Moreover, the growth status etc. of the cultivated plant P can be easily confirmed, and it is possible to cultivate while having fun.
 上記複層ガラス205に代えて、他の材質のものを採用することもできる。但し、複層ガラス205は、断熱性が有り、透視性にも優れていることから好ましい材料である。中でも、空気層のガラス面に所定の金属膜を貼設して構成した低放射性ガラス(Low-Eガラス)は、きわめて高い断熱性ないし遮熱性を発揮するものであり、適している。 Instead of the multi-layer glass 205, other materials can be used. However, the multi-layer glass 205 is a preferable material because it has heat insulation properties and excellent transparency. Among these, low-radiation glass (Low-E glass) formed by pasting a predetermined metal film on the glass surface of the air layer is suitable because it exhibits extremely high heat insulating properties or heat shielding properties.
 箱体202内部には、図15に示すように、主として栽培ベッド210、冷蔵ユニット211、養液ユニット212が格納されている。冷蔵ユニット211および養液ユニット212は、箱体202のそれぞれ最上段および最下段に配置されており、その中間に栽培ベッド210が上下複数段に亘って配置されている。各栽培ベッド210の上方には、天井部215および空調装置216が配設されている。
 実施例1ですでに述べたように、栽培ベッド210を、育成用と育苗用とに分けて配置し、育苗用で所定期間育てた苗を、育成用に移し替え、その後栽培植物Pとして育成するようにしてもよい。
 箱体202は密閉可能な構造を有しており、給気ファン211aや吸込口211bを適宜備えた冷蔵ユニット211によって、内部の温度や湿度等が、年間を通して栽培植物Pの生育に最適な一定範囲に調整されるようになっている。吸込口211bを、図15に示す如くの位置に設けると、箱体202内部の温かい空気は上昇してくるため、空気を循環させ易いものとなる。
As shown in FIG. 15, a cultivation bed 210, a refrigeration unit 211, and a nutrient solution unit 212 are mainly stored inside the box 202. The refrigeration unit 211 and the nutrient solution unit 212 are disposed at the uppermost and lowermost stages of the box 202, respectively, and the cultivation bed 210 is disposed across a plurality of upper and lower stages in the middle. Above each cultivation bed 210, a ceiling 215 and an air conditioner 216 are disposed.
As already described in Example 1, the cultivation bed 210 is arranged separately for growing and for raising seedlings, and the seedlings grown for a predetermined period for raising seedlings are transferred to growing, and then grown as cultivated plants P. You may make it do.
The box 202 has a structure that can be hermetically sealed, and the internal temperature, humidity, and the like are constant for optimum growth of the cultivated plant P throughout the year by the refrigeration unit 211 that is appropriately provided with the air supply fan 211a and the suction port 211b. The range is adjusted. When the suction port 211b is provided at a position as shown in FIG. 15, the warm air inside the box 202 rises, so that the air can be easily circulated.
 養液ユニット212は、図15に示すように、ポンプ220、タンク221、ろ過器222、殺菌器223などから構成されており、各栽培ベッド210に養液Aを循環供給している。
 タンク221に貯留される養液Aは、ポンプ220によってポンプアップされ、給液管225を介して各栽培ベッド210に供給される。養液Aとしては、液肥を希釈したものが用いられる。各栽培ベッド210から排出された養液Aは、排液管226を介して、再びタンク221に回収される。排液管226とタンク221との間には、フィルターからなるろ過器222と、オゾン、紫外線等を利用した殺菌器223が介設されており、汚泥や塵埃等が取り除かれるようになっている。
 なお、必要に応じて、電磁弁や逆流を防止する逆止弁、さらに排液を再利用しない場合にそのまま排出する排出手段等を各所に適宜設けるようにしてもよい。
As shown in FIG. 15, the nutrient solution unit 212 includes a pump 220, a tank 221, a filter 222, a sterilizer 223, and the like, and circulates and supplies the nutrient solution A to each cultivation bed 210.
The nutrient solution A stored in the tank 221 is pumped up by the pump 220 and supplied to each cultivation bed 210 through the liquid supply pipe 225. As the nutrient solution A, a solution obtained by diluting liquid fertilizer is used. The nutrient solution A discharged from each cultivation bed 210 is again collected in the tank 221 through the drainage pipe 226. Between the drainage pipe 226 and the tank 221, a filter 222 made of a filter and a sterilizer 223 using ozone, ultraviolet light or the like are interposed so that sludge, dust, and the like are removed. .
If necessary, an electromagnetic valve, a check valve for preventing backflow, and a discharge means for discharging the liquid as it is when not reused may be provided at various places.
 また、タンク221には、養液Aの濃度、容量や温度をセンサー等によって一定の値に保持する自動管理手段を設けることもできる。但し、装置が過大になるのを防ぐために、このような手段の付設を省略し、養液Aを定期的(例えば2ヶ月ごと)に新しいものに交換するようにしてもよい。 Also, the tank 221 can be provided with an automatic management means for holding the concentration, volume and temperature of the nutrient solution A at a constant value by a sensor or the like. However, in order to prevent the apparatus from becoming excessive, the provision of such means may be omitted, and the nutrient solution A may be replaced with a new one periodically (for example, every two months).
 栽培ベッド210は、例えば直方体枠組み状に剛構成された架台(図示せず)によって、それぞれ略水平をなして配設保持されている。栽培ベッド210の段数は、設置場所や植物の種類等によっても異なるが、3~5段程度とするのが、省スペースや生産効率等の点から好ましい。 The cultivation bed 210 is arranged and held substantially horizontally, for example, by a gantry (not shown) rigidly configured in a rectangular parallelepiped frame shape. The number of stages of the cultivation bed 210 varies depending on the installation location, the type of plant, and the like, but is preferably about 3 to 5 stages from the viewpoint of space saving and production efficiency.
 栽培ベッド210はそれぞれ、図16(a)(b)に示すように、矩形板状(約850mm×450mm×90mm)をなし、上部開放箱型の栽培槽230と、栽培槽230上部の所定位置に嵌着される植付パネル231とから構成されている。
 栽培槽230の底面230aと植付パネル231との間には、養液Aの流路233が形成されている(図16(c))。そして、給液管225から分岐管225aを介して供給される養液Aが、給液部225bの給液口225cから栽培ベッド210に流入し、この流路233を連続的に通過して、栽培槽230側面の所定位置に穿設される排液口226b、および排液口226bに接続される分岐管226aを介して、排液管226へと流下排出されるようになっている。
Each of the cultivation beds 210 has a rectangular plate shape (about 850 mm × 450 mm × 90 mm) as shown in FIGS. 16 (a) and 16 (b), and a predetermined position on the upper open box type cultivation tank 230 and the cultivation tank 230. It is comprised from the planting panel 231 fitted by.
Between the bottom surface 230a of the cultivation tank 230 and the planting panel 231, the flow path 233 of the nutrient solution A is formed (FIG. 16C). And the nutrient solution A supplied from the liquid supply pipe 225 via the branch pipe 225a flows into the cultivation bed 210 from the liquid supply port 225c of the liquid supply part 225b, and continuously passes through this flow path 233, A drainage port 226b drilled at a predetermined position on the side surface of the cultivation tank 230 and a branch pipe 226a connected to the drainage port 226b are discharged and discharged to the drainage tube 226.
 植付パネル231には、栽培植物Pを植付状態とするためのポット235を支持するポット受孔231aが適宜の間隔で多数設けられている。図16(c)に示すように、ポット受孔231aは、下窄りで、上下に連通した形状をなす。これに対して、ポット235は、ポット受孔231aに対応し且つ底部が開放された形状をなし、栽培植物Pの苗を培土とともに収容している。そして、栽培植物Pの植物根P’が、ポット235を貫通して、植付パネル231の下方に露出するようにして配設されている。 The planting panel 231 is provided with a number of pot receiving holes 231a that support the pot 235 for placing the cultivated plant P in a planted state at appropriate intervals. As shown in FIG. 16 (c), the pot receiving hole 231a has a shape that communicates vertically with a narrowed bottom. On the other hand, the pot 235 has a shape corresponding to the pot receiving hole 231a and an open bottom, and accommodates the seedling of the cultivated plant P together with the cultivated soil. The plant root P ′ of the cultivated plant P is disposed so as to penetrate the pot 235 and be exposed below the planting panel 231.
 養液Aは、養液ユニット212のポンプ220に接続されるモータ(図示せず)を介して、流路233に間欠的に流入するように電磁制御されている。養液Aの供給を一定時間ごとにストップし、植物根P’に養液Aと空気を交互に触れさせることで栽培植物Pの成長をさらに促進することができる。そのため、植付パネル231に空気を取り込むための多数の透孔を設けたり、植付パネル231自体をメッシュ状に形成すればより好ましい。 The nutrient solution A is electromagnetically controlled so as to intermittently flow into the flow path 233 via a motor (not shown) connected to the pump 220 of the nutrient solution unit 212. The supply of the nutrient solution A is stopped at regular intervals, and the growth of the cultivated plant P can be further promoted by alternately contacting the nutrient solution A and air with the plant root P ′. Therefore, it is more preferable to provide a large number of through holes for taking air into the planting panel 231 or to form the planting panel 231 itself in a mesh shape.
 また、栽培ベッド210では、図16(a)(b)に示すように、栽培槽230の底面230aに調整板237と堰板238とが立設配置されており、これら調整板237と堰板238との間に植付パネル231が嵌着されている。堰板238は、栽培槽230における流路233の下流側に形成してあり、養液Aが所定量になると堰板238を超えて、排液口226bへと流出するような構成となされている。調整板237の下部は横長に切欠して構成されており、給液口225cから流下した養液Aを、流路233に流入させている。これにより、流路233内を養液Aで略一杯に満たし、流路233に向けて露出した植物根P’が流路233を通過する養液Aに接触して、養液A中の栄養分を十分に吸収できるようになされている。 Moreover, in the cultivation bed 210, as shown to Fig.16 (a) (b), the adjustment board 237 and the weir board 238 are standingly arranged by the bottom face 230a of the cultivation tank 230, These adjustment board 237 and a weir board are arranged. The planting panel 231 is fitted between the two. The dam plate 238 is formed on the downstream side of the flow path 233 in the cultivation tank 230, and when the nutrient solution A reaches a predetermined amount, the dam plate 238 flows over the dam plate 238 to the drainage port 226b. Yes. The lower part of the adjusting plate 237 is configured to be cut out in a horizontally long shape, and the nutrient solution A flowing down from the liquid supply port 225 c flows into the flow path 233. As a result, the inside of the flow path 233 is almost completely filled with the nutrient solution A, and the plant root P ′ exposed toward the channel 233 comes into contact with the nutrient solution A passing through the channel 233, so that the nutrients in the nutrient solution A It is made to be able to absorb enough.
 なお、堰板238の下部には、小孔239が適宜箇所に設けられており(図16(a)(b))、養液Aの供給をストップした際に、流路233内の養液Aを残らず排液管226へと排出できるようになっている。養液Aを排出し、植物根P’に空気を触れさせることで、植物根P’が刺激を受け、次に流入してくる養液Aを活発に吸い上げる。これによって、栽培植物Pの成長が促進される。 A small hole 239 is provided at an appropriate position below the barrier plate 238 (FIGS. 16A and 16B), and when the supply of the nutrient solution A is stopped, the nutrient solution in the flow path 233 is provided. All of A can be discharged to the drainage pipe 226. By discharging the nutrient solution A and allowing the plant root P 'to come into contact with air, the plant root P' is stimulated and actively sucks the nutrient solution A that flows in next. Thereby, the growth of the cultivated plant P is promoted.
 栽培植物Pとしては、野菜や果物など様々な種類の植物が対象となる。特に流路233内の養液Aが常に新鮮な状態に保たれることから、将来的には山葵や生姜なども好適に採用され得る。 As the cultivated plant P, various types of plants such as vegetables and fruits are targeted. In particular, since the nutrient solution A in the flow path 233 is always kept fresh, yam or ginger can be suitably employed in the future.
 図17、図18に示すように、各栽培ベッド210の上方には、それぞれ栽培植物Pを照射するための人工光源240を有する天井部215が配設されている。天井部215は、栽培ベッド210と同程度の面積を有しており、手動または自動の走行手段を介して、栽培ベッド210に対して上下移動自在に構成されている。本実施例では、走行手段として天井部215の上側に駆動部218を採用している(図17参照)。この駆動部の機構は、すでに実施例1で述べた、軸ボルト、左右一対のアーム、従動部、螺合部、吊設部材、操作ハンドルからなる機構、又は、軸ボルト、内側滑車、外側滑車、螺合部、吊設部材、操作ハンドルからなる機構、を小型化したものとする。これにより、天井部215は、栽培ベッド210に対して上下移動自在となる。 17 and 18, a ceiling portion 215 having an artificial light source 240 for irradiating the cultivated plant P is disposed above each cultivation bed 210. The ceiling part 215 has the same area as the cultivation bed 210 and is configured to be movable up and down with respect to the cultivation bed 210 via manual or automatic traveling means. In the present embodiment, a driving unit 218 is employed on the upper side of the ceiling 215 as a traveling means (see FIG. 17). The mechanism of this drive unit is the mechanism comprising the shaft bolt, the pair of left and right arms, the driven portion, the screwing portion, the suspension member, and the operation handle, as already described in the first embodiment, or the shaft bolt, the inner pulley, and the outer pulley. , A mechanism including a screwing portion, a suspension member, and an operation handle is miniaturized. Thereby, the ceiling part 215 becomes movable up and down with respect to the cultivation bed 210.
 天井部215および人工光源240は、栽培植物Pの成長に応じて上下移動させられる。光の強度や量が不足すると栽培植物Pの成長が遅れ、逆に過剰であると栽培植物Pに焼け等が生じる結果となる。上記天井部215によれば、人工光源240と栽培植物Pとの間の距離を常に適正(通常10~20cm程度)に保つことが容易であり、栽培植物Pの成長を促進することが可能となる。 The ceiling part 215 and the artificial light source 240 are moved up and down as the cultivated plant P grows. If the intensity or amount of light is insufficient, the growth of the cultivated plant P is delayed. Conversely, if it is excessive, the cultivated plant P is burned. According to the ceiling part 215, it is easy to keep the distance between the artificial light source 240 and the cultivated plant P always appropriate (usually about 10 to 20 cm), and the growth of the cultivated plant P can be promoted. Become.
 人工光源240としては、栽培植物Pの成長にとって好ましい波長域となるように、蛍光灯、冷陰極ランプ、LED等を単独でまたは複数組み合わせて用いることができる。特にLEDは、温度上昇が低く、耐久性にも優れるため、適したものとなる。 As the artificial light source 240, a fluorescent lamp, a cold cathode lamp, an LED, or the like can be used alone or in combination so that the wavelength range is preferable for the growth of the cultivated plant P. In particular, LEDs are suitable because they have a low temperature rise and excellent durability.
 天井部215の下面には、実施例2ですでに述べたように、傾斜壁面242及び凹部243が、栽培ベッド210に略等しい左右幅で、且つ長辺に略並行して2列に形成されることとしてもよい(図18参照)。 On the lower surface of the ceiling portion 215, as already described in the second embodiment, the inclined wall surface 242 and the concave portion 243 are formed in two rows with a lateral width substantially equal to the cultivation bed 210 and substantially parallel to the long side. (See FIG. 18).
 図17、図18に示すように、各栽培ベッド210は、後方に空調装置216を備えている。空調装置216は、栽培ベッド210の左右幅に略相当する全長を有する筒体をなし、伸縮自在のフレキシブルダクト251および分岐ダクト252を介して、給気ファン211aから下方に延出したダクト250に接続されている。
