Description

TECHNICAL FIELD The present invention relates to a plant cultivation apparatus and a plant cultivation method used, for example, for cultivation in a plant factory.

Conventionally, in a plant factory or the like, plant cultivation is performed by combining artificial light illumination and hydroponics. While temperature control of the cultivation area is indispensable for such plant cultivation, there is a problem that the heat radiation from the lighting device used for artificial lighting raises the temperature of the cultivation area. As one of the countermeasures, it is conceivable to use solid-state light-emitting elements such as LEDs with relatively high energy efficiency in the lighting device to suppress the amount of heat generated by the lighting device.

However, even in a lighting device with relatively high energy efficiency, about 70% of the energy is generally radiated as heat, so the amount of heat generated from the lighting device is still not negligible. In addition, very little of the light emitted from the lighting device is used for photosynthesis in plants, and most of it is finally converted into heat.

On the other hand, the transpiration of water from the plants also increases the humidity in the cultivation area. Become.

That is, when cultivating plants in a closed space such as a plant factory, an air conditioning system is essential to prevent the space from being filled with high-temperature, high-humidity air.

Patent Document 1 shows an example of such an air conditioning system, and in order to make the temperature and humidity uniform in a large cultivation area, air circulation is attempted by installing a fan or the like. It is difficult to evenly circulate the air between

Furthermore, as in the air conditioning system described in Patent Document 2, if a reflector is provided on a shelf to prevent light from leaking out, the air tends to stagnate. A countermeasure such as using a large fan is necessary, but such a countermeasure causes an increase in cost. In addition, considering the effect on plant growth, if the wind speed is to be suppressed, there is a risk that effective air circulation will not be possible unless fans are installed at regular intervals, so increasing the number of fans will reduce space efficiency. will also invite

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned matters, and its object is to provide a plant cultivation apparatus and a plant cultivation method capable of achieving good air conditioning control necessary for plant cultivation and also improving space efficiency. is to provide

In order to achieve the above object, a plant cultivation apparatus according to the present invention includes a plurality of lane bodies arranged at intervals in the vertical direction and having therein a ventilation passage extending in the longitudinal direction thereof; a conveying device for conveying the cultivation bottle along a direction; a lighting device arranged on the lower surface of the lane body for irradiating the cultivation bottle with light; A plurality of ventilation openings communicating with the ventilation path are formed on the upper surface of the lane body at intervals from one end side to the other end side in the longitudinal direction of the lane body, and the ventilation openings are formed in a space above the lane body. and the portion located above the air passage in the lane body is thinner than the portion located below, the vent is provided in the portion located above, and the portion located below and the transport device has a plurality of rotating bodies rotatably arranged on both sides of the lane body in the lateral direction in a plan view, and each rotating body is attached to the lane body. It is provided in a state of protruding upward from the upper surface (Claim 1).

In the above plant cultivation apparatus, the plurality of lane bodies are arranged three-dimensionally with intervals in both the vertical direction and the horizontal direction, and at least one of the horizontal interval and the vertical interval is It may be uneven (Claim 2).

In the above plant cultivation apparatus, the lane body may be inclined so as to become lower from one end side to the other end side (Claim 3).

In the above plant cultivation apparatus, the cultivation bottle may be configured to move in the conveying direction using its own weight (Claim 4).

In the plant cultivating apparatus, the area and/or density of the air vents may increase with increasing distance from a portion of the air passage connecting to the air blower (claim 5).
In addition, the plant cultivation device has a hanging basket body that is transported in a suspended state by the transport device, and the hanging basket body has a cultivation bottle placed on an upper part that is transported on the transport device, and , It may be possible to place another cultivation bottle on the lower part of the lower surface of the lane body that supports the transport device, which is transported below the lighting device (Claim 6).

On the other hand, in order to achieve the above object, a plant cultivation method according to the present invention cultivates a plant using the plant cultivation apparatus according to any one of claims 1 to 6 (claim 7).

INDUSTRIAL APPLICABILITY According to the present invention, a plant cultivation apparatus and a plant cultivation method can be obtained, which can satisfactorily perform air conditioning control necessary for plant cultivation and also improve space efficiency.

That is, in the plant cultivation apparatus of the invention according to each claim of the present application, by operating the air blower, the air whose temperature has been raised by the heat radiation of the lighting device and the water vapor derived from the plants held in the cultivation bottle are removed from the lighting device. Air can be sucked in through vents near plants and discharged outside through ventilation channels, or low-temperature and low-humidity air can be exhaled from vents, resulting in large unevenness in temperature and humidity distribution in the cultivation area. It is easy to turn off the air conditioning, and the air-conditioning control required for plant cultivation can be performed very well.
Here, when air is sucked through the vent and discharged to the outside, it is preferable to dispose the vent above the plants held in the cultivation bottle so that mainly warm air can be discharged. Conversely, when cold air is discharged from the vent, it is preferable to discharge it from below the plant. Then, for example, it is possible to provide both a ventilation path for sucking air from a ventilation port and discharging it to the outside and a ventilation path for discharging air from the ventilation port.

In addition, since the air passages and vents for air conditioning control can be configured to be not large and bulky, it also contributes to the improvement of space efficiency.

Furthermore, in the plant cultivating apparatus of the present invention, since the vent on the upper surface of the lane body communicates with the upper space of the lane body, when the air blower is not operating, the temperature rises due to heat radiation from the lighting device. By forming such an air flow, it becomes difficult for the temperature and humidity around the plant to rise immediately, and this is due to the operation of the blower. It can also lead to improvement in air conditioning energy efficiency due to shortening of time. This effect is obtained by tilting the lane body, as in the plant cultivation apparatus according to claim 3, so that the air flowing upward along the tilt in the space below the lane body and in the ventilation passage is also produced. It can be further enhanced by making it easier to generate.

Here, when cultivating plants continuously from the initial stage of growth in one plant cultivating apparatus, a plurality of lane bodies are spaced both vertically and horizontally in order to increase space efficiency. When arranging them three-dimensionally, it is conceivable to make the horizontal and vertical intervals non-uniform. In the conventional air-conditioning system, if the shelves are unevenly arranged, the flow of air tends to become stagnant, especially in areas where the shelves are densely packed, and there is a high tendency to hinder air-conditioning management. In the plant cultivation apparatus, as described in claim 1, since a plurality of ventilation holes are provided at intervals from one end side to the other end side in the longitudinal direction of the lane body, even if the arrangement of the lane bodies is uneven, In particular, it is possible to avoid the inconvenience that the air flow tends to be stagnant in areas where the lane bodies are densely packed.

In the plant cultivation apparatus according to claim 4, the energy required for conveying the cultivation bottles can be reduced or eliminated, and energy saving can be realized accordingly. In addition, the more energy consumption can be reduced, the more the temperature rise of the air inside the apparatus can be suppressed, and the environment inside the apparatus suitable for the growth of cultivated plants can be easily maintained accordingly.

In the plant cultivation apparatus according to claim 5, the amount of air taken in or discharged from the vents can be made uniform, contributing to further improvement in air conditioning management.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 6 to 8, in the plant cultivation apparatus 1 of this example, a plurality of lane bodies 3 (for example, nine or more) are arranged three-dimensionally at intervals in both the horizontal direction and the vertical direction. , so that the spaces around the lane bodies 3 lined up in this manner communicate with each other, so that partition walls or the like are not provided.

Although not clearly shown in FIGS. 6 to 8, as shown in FIGS. 1 to 5 (particularly FIGS. 3 to 5), the plant cultivation apparatus 1 includes cultivation bottles (not shown) holding plants. (not included) is arranged in the direction of conveying, and the ventilation path 2 is formed inside the lane body 3. In addition, the cultivation bottle is conveyed along the longitudinal direction X of the lane body 3. A device 4 and a plurality of lighting devices 5 arranged on the lower surface of the lane body 3 to irradiate the cultivation bottles with cultivation light and thermally and closely connected to the formation part of the ventilation path 2 are provided. That is, the plant cultivation apparatus 1 is configured to appropriately irradiate the plants held in the cultivation bottles with light from the illumination device 5 and convey the cultivation bottles by the conveying device 4 .

The air passage 2 is a passage formed so as to hollow out the interior of the lane body 3 made of a metal such as aluminum having excellent thermal conductivity. A plurality of intake ports (an example of ventilation ports) 2A are formed at intervals over the other end side 3B.

The intake port 2A preferably has a mechanism for preventing the intrusion of foreign matter such as dust. , the intake port 2A may be covered with a separate filter.

The lane body 3 has a large number of rotating bodies (rollers) rotatably arranged on both sides of the conveying device 4, so that the cultivation bottle or the cultivation bottle arranged on the lane body 3 can be detachably attached. It supports a holder (a dish, a basket body, etc.) to be movable in the longitudinal direction X. The conveying device 4 of the present embodiment is provided with a driving mechanism (motor) 4A for supplying driving force to, for example, important rollers, and a power transmission shaft 4B (see FIG. 4). Although not shown, it is preferable that the roller is formed by winding a power transmission flexible member such as a belt or wire around the roller. The drive mechanism 4A is preferably provided on the side where the culture bottle transfer mechanism 10, which will be described later, does not exist.

In addition, as shown in FIGS. 6 and 8, each lane body 3 is inclined from one end side 3A toward the other end side 3B so as to be lowered, and the weight of the cultivation bottle itself moves in the conveying direction. It is made to occur.

The lighting device 5 preferably emits light (cultivation light) having a wavelength suitable for growing a cultivated plant to be cultivated. Discharge tubes such as gas lamps and electrodeless lamps, and filament light-emitting elements such as gas lasers and incandescent lamps can be used, but are not particularly limited to these. However, from the point of view of high luminous efficiency, it is preferable to use a solid-state light-emitting device such as an LED, an OLED, or a laser as the lighting device 5 . For example, the lighting devices 5 may be arranged dispersedly on the lower surface of the lane body 3 or may be arranged continuously in the longitudinal direction thereof. You have to decide the placement. Further, in order to make the thermal connection between the lighting device 5 and the lane body 3 tight, the lighting device 5 may be attached to the lane body 3 via heat dissipating silicone having excellent insulation and thermal conductivity, for example. .

In addition, as shown in FIG. 5, the plant cultivation apparatus 1 is connected to one end of the ventilation path 2 and is connected to the ventilation path 2, and the heat of the lighting device 5 is transferred to the plant cultivation apparatus by using the air taken in from the intake port 2A. 1, a suction pump is provided as an exhaust device (an example of a blower device) 6 for discharging the air to the outside. In addition, the control circuit 5A that irradiates the lighting device 5 with an appropriate intensity of cultivation light (adjusts the light intensity) by supplying adjusted electric power to the lighting device 5 is separated from the lane body 3 as much as possible. It is arranged in a physically isolated position to prevent the heat generated from the control circuit 5A from diffusing into the device.

Furthermore, as shown in FIGS. 6 to 8, the plant cultivation apparatus 1 includes a cultivation bottle transfer mechanism 10 that transfers cultivation bottles to and from the conveying device 4 at the end of the lane body 3 . The cultivation bottle transfer mechanism 10 of the present embodiment transfers (carries in) the cultivation bottle to the carrier device 4 or the holder on the lane body 3 at one end side 3A of the lane body 3, for example, and the cultivation bottle or the cultivation bottle by the carrier device 4 A carry-in mechanism 10A that enables the movement of the holding body that holds it, and a carry-out mechanism 10B that transfers (carries out) the cultivation bottle that has moved on the lane main body 3 on the other end side 3B of the lane main body 3. , and a transfer means 10C for transferring the cultivation bottle transferred to the carry-out mechanism 10B to the one end side 3A of another lane body 3.

As clearly shown in FIG. 7, the lane bodies 3 are three-dimensionally arranged with intervals in both the horizontal direction and the vertical direction according to the growth of the cultivated plants mounted on the cultivation bottles. That is, for example, in the initial stage when the plants to be mounted on the cultivation bottles have not yet grown, the cultivation bottles are mounted on all the lane bodies 3 arranged horizontally in six rows provided at the bottom to maximize the space. It is possible to perform cultivation that makes the best use of it.

Next, when the plants grow to a certain extent, the lane bodies 3 arranged in five rows in the horizontal direction are sequentially used to grow the plants as shown in the second to fourth rows from the bottom, and when the plants grow further. , the lane bodies 3 arranged in four rows in the horizontal direction, as shown in the fifth to ninth rows from the bottom, can be used successively to further grow plants.

That is, since the horizontal and vertical intervals at which the lane bodies 3 are provided are adjusted in accordance with the growth of the cultivated plants, when the cultivation bottles are moved to the lane bodies 3, the cultivation bottles are moved to the growth stage of the plants. It can be moved to the transport device 4 of another lane body 3 according to the requirement. As the cultivation bottle moves between the lane bodies 3, the distance between the cultivated plant and the illumination changes, so that the cultivated plant can be properly irradiated with light of an appropriate intensity required by the cultivated plant. By arranging the horizontal and vertical intervals of the lane bodies 3 in at least three stages, it is possible to sufficiently cope with the growth of cultivated plants and to make the configuration of the plant cultivation apparatus 1 unnecessary. It can't be complicated.

Here, it is conceivable to provide air conditioning means (air conditioner) for air conditioning the cultivation area in which the plant cultivation apparatus 1 is arranged, and the air conditioning means can control at least one of the temperature and humidity of the cultivation area. Examples include, but are not limited to, absorption refrigerators, electric refrigerators, heat pump chillers, and desiccant air conditioners.

According to the plant cultivating method using the plant cultivating apparatus 1 configured as described above, by operating the exhaust device 6, the air whose temperature has increased due to the heat radiation of the lighting device 5 and the water vapor derived from the plant P etc. The air can be sucked in through the air intake port 2A near the lighting device 5 and the plant P and discharged to the outside through the ventilation path 2, and it is easy to prevent the temperature distribution and humidity distribution in the cultivation area from being greatly uneven. , the air conditioning control necessary for plant cultivation can be performed very well. Moreover, when conditioned air is supplied to the cultivation area by, for example, an air conditioner or the like, by providing the air intake port 2A at an appropriate position of the lane body 3, the supplied conditioned air can be distributed between the adjacent lane bodies 3. It can be pulled into a crowded space, etc., and air conditioning can be managed evenly and reliably throughout the cultivation area.

In addition, the ventilation path 2 and the intake port 2A for performing this air conditioning control can be provided in the lane body 3, and since they are not large and bulky, they also contribute to the improvement of space efficiency. Further, the effect of improving the spatial efficiency can be further enhanced by providing the lane main body 3 with a function to hold the transport device 4 and the lighting device 5, thereby eliminating the need for a configuration for separately holding the transport device 4 and the lighting device 5. can be enhanced. Desirably, the ventilation path 2, the intake port 2A, the conveying device 4, and the lighting device 5 are integrated with the lane body 3, and the height of the lane body 3 is suppressed to one-third or less of the cultivation space. As a result, the growth environment of cultivated plants can be appropriately maintained, and more plants can be cultivated.

Furthermore, as described above, the lane body 3 is made of a material such as a metal having excellent thermal conductivity, the ventilation path 2 is provided therein, and the lane body 3 holds the lighting device 5. 5 is thermally closely connected to the lane body 3, the lighting device 5, which dissipates heat, can be efficiently cooled, and further simplification of air-conditioning management can be expected.

On the other hand, in the plant cultivation apparatus 1 of this example, the intake port 2A on the outer surface (upper surface) of the lane body 3 communicates with the upper space of the lane body 3. Therefore, when the exhaust device 6 is not in operation, , the upward flow of the air whose temperature has been raised by the heat radiation of the lighting device 5 is not hindered, and the formation of such an air flow makes it difficult for the temperature and humidity around the plant P to immediately rise significantly. This can lead to an improvement in air-conditioning energy efficiency due to shortening of the operating time of the exhaust device 6 and the like. This effect is achieved by tilting the lane body 3 as described above and facilitating the generation of an upward air flow along the tilt in the space below the lane body 3 and in the ventilation passage 2. , will be further enhanced.

Moreover, if the lane main body 3 is provided with an inclination so that the cultivation bottle moves in the conveying direction using its own weight, the conveying device 4 does not need to be provided with the drive mechanism 4A or the like, thereby simplifying the configuration. You can also plan.

On the other hand, in the plant cultivating apparatus 1 of this example, the plant P can be cultivated continuously within one plant cultivating apparatus 1 from, for example, the initial stage of its growth. In order to arrange the lane bodies 3 three-dimensionally with intervals in both the vertical direction and the horizontal direction, the intervals in the horizontal direction and the intervals in the vertical direction are made uneven. Here, in a conventional air conditioning system, if the shelves are arranged in a dense or sparse manner, the flow of air tends to become stagnant, particularly in areas where the shelves are densely packed, and there is a high tendency to hinder air conditioning management. In the cultivation device 1, since the air inlet 2A is provided in the lane body 3, even if the arrangement of the lane bodies 3 is uneven, it is possible to avoid the inconvenience that the flow of air tends to be stagnated especially in the area where the lane bodies 3 are densely packed. can be done.

By the way, in this example, a plurality of air inlets 2A are formed at intervals from one end side 3A to the other end side 3B of the lane body 3. The plurality of air inlets 2A have the same size and are provided at regular intervals. In this case, the intake port 2A close to the exhaust device 6 in the lane body 3 draws a large amount of air, and the amount of air drawn from the intake port 2A decreases as the distance from this point increases. Therefore, it is preferable from the standpoint of air conditioning management that the area and/or density of the air intake port 2A increase with increasing distance from the portion of the lane main body 3 connected to the exhaust device 6, thereby making the amount of air drawn in uniform. In addition, in the examples of FIGS. 1, 2, and 5, the intake port 2A is made larger toward the one end side 3A.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be modified in various ways without departing from the gist of the present invention. For example, the following modifications can be given.

The cultivation bottle may hold one plant P or may hold a plurality of plants P. When holding a plurality of plants, the number of plants P may be 100 or less, 50 or less, 20 or less, or 10 or less. Especially when the plant P is small, it is preferable to hold (set) a plurality of plants in one cultivation bottle. In addition, it is conceivable that the size of the cultivation bottle is set to 5 types or less, preferably 3 types or less, or only 1 type. Here, dimensional differences of ±20% or less are included in one type.

Further, the cultivation bottle accommodates at least a nutrient solution (and/or water) in addition to the plant P, and the plant cultivation apparatus 1 includes a station for supplying the nutrient solution (and/or water) to the cultivation bottle. It may be arranged such that the transfer to this station is carried out by the transfer device 4 .

In the above example, an example in which the driving device 4A is provided in the conveying device 4 is shown, but this may be omitted and the cultivation bottle may be conveyed using its own weight (in this case, the conveying device 4 It is conceivable that it is composed of a rotating body such as a roller or a wheel). Conversely, the driving device 4A may be provided for each roller, and the lane body 3 may be horizontally arranged and conveyed by the driving device 4A.

Here, individual cultivation bottles can be conveyed by the conveying device 4, for example, when the conveying device 4 is a horizontal conveyor, by simply placing the cultivation bottles at appropriate intervals. For example, a guide mechanism may be provided so as to prevent this from occurring. In addition, when the lane body 3 is inclined and the conveying device 4 conveys the cultivation bottles by their own weight, the cultivation bottles may be conveyed by closing the gaps between the cultivation bottles, but for example, spacers may be provided in the cultivation bottles themselves. Alternatively, the spacing between adjacent cultivation bottles may be adjustable by appropriately setting the dimensions of a holder such as a plate that detachably holds the cultivation bottles. Furthermore, the holders that detachably hold the cultivation bottles may be spaced apart at appropriate intervals so that each holder can move. In any case, when the cultivation bottle is conveyed alone, for example, the cultivation bottle transfer mechanism 10 may be configured to transfer the cultivation bottle to and from the conveying device 4, but the cultivation bottle is held. When the cultivation bottle is detachably held by the body and transported, for example, the cultivation bottle transfer mechanism 10 needs to be provided with a mechanism for attaching and detaching the cultivation bottle to and from the holder.

In addition, the cultivation bottle is not limited to moving on the lane body 3 by the transport device 4 such as a roller or a belt, and may be transported in a state of being suspended below the lane body 3, for example. good. In the case of directly hanging the cultivation bottle, for example, a flange may be provided on the cultivation bottle, and the flange may be used for hanging. Of course, a holding body capable of holding the cultivation bottle in a suspended state may be provided and the holding body may be conveyed by the conveying device 4 .

Then, a plurality of transportation methods may be combined, or a cultivation bottle may be transported using a holder capable of realizing a plurality of transportation methods. For example, in FIG. 9, a conveying surface 11 that is conveyed on the conveying device 4 is provided, and another cultivation bottle B is detachably attached below the lighting device 5 on the lower surface of the lane body 3 that supports the conveying device 4. The cultivation bottle B is placed on the conveying surface 11 and can be moved in the conveying direction X (see FIG. 1 etc.) of the lane body 3 in a state where the cultivation bottle B is held in the concave portion 12. (an example of a holder) 13 is shown, and transportation using such a basket body 13 is also possible. In this example, the dimensions such as the width W and the height H of the basket body 13 may be changed according to the size of the plant P held in the cultivation bottle B, for example, large, medium and small. The hanging basket body 13 may be prepared by dividing into three types. Moreover, the suspension basket body 13 of this example is particularly suitable for use in the lowermost lane body 3 .

In the example of FIG. 9, in addition to the concave portion 12, a concave portion 14 capable of detachably holding the cultivation bottle B is also formed on the upper surface of the conveying surface 11. The bottles B may be placed only on the top (conveying surface 11) and bottom of the basket body 13, respectively. In any case, the upper part (conveying surface 11) and the lower part of the basket body 13 are at least on one side in the left-right direction (the direction orthogonal to the conveying direction X in plan view), as indicated by the arrow Y, by the cultivation bottle transfer mechanism. It is preferable to have an open space so that the cultivation bottle B can be easily transferred and attached/detached by 10 . Alternatively, as indicated by an arrow Y', for example, the entire basket body 13 may be detachable from the conveying device 4.

FIG. 10 is a plan view showing a modification of the plant cultivation apparatus of the present invention. As shown in FIG. 10, by curving the lane body 3' into a substantially U-shape and bringing the positions of the one end side 3A and the other end side 3B close to each other, one side of the lane body 3' can be used as a cultivation bottle transfer mechanism 10'. The cultivation bottle B may be transferred and attached/detached only on the side of . Note that the lane body 3 is not limited to being linear or U-shaped in a plan view, and may have various shapes such as a zigzag shape and a spiral shape.

In addition, in order to allow the cultivation bottle transfer mechanism 10 to be provided only on one side of the lane body 3, the conveying device 4 may be configured so that the cultivation bottle can be reciprocated along the lane body 3, or the lane body 3 It is also conceivable that a plurality of cultivation bottles that have reached the opposite side of the container are collectively returned to one side.

In the above example, one air passage 2 is provided inside the lane body 3, but a plurality of air passages 2 may be provided. You may make it differ.

In the above example, the lane body 3 also serves as the ventilation pipe having the ventilation path 2, but the ventilation pipe having the ventilation path 2 may be provided separately from the lane body 3. In this case, the ventilation pipe is the lighting device. 5 (a position that does not interfere with the light irradiation by the lighting device 5). A ventilation pipe may be provided so as to be positioned on the front side of the device 5 (position that prevents light irradiation by the lighting device 5).

In the above example, the exhaust device 6 is provided as the blower and sucks air from the intake port 2A. However, the present invention is not limited to this, for example, an air supply device is provided as the blower to discharge air from the intake port 2A. (The intake port 2A serves as an air supply port.) In this case, the temperature and humidity of the supplied air may be adjusted (dehumidified).

In the above example, the intake port 2A is provided on the upper surface of the lane body 3 (vent pipe), but the position where the intake port 2A is provided is not limited to the upper surface. can be Furthermore, in the example of FIG. 1, etc., a plurality of air intake ports 2A are provided, but for example, only one slit-shaped air intake port 2A connecting these may be provided. , it is conceivable that the lane body 3 (ventilation pipe) is made larger as it moves away from the portion connected to the exhaust device 6 .

In the above example, the ventilation path 2 (ventilation pipe 3), the conveying device 4, and the lighting device 5 are arranged along the lane body 3, respectively. may be provided along a direction different from the direction in which the lane body 3 extends.

In addition, it cannot be overemphasized that you may combine suitably the modification mentioned in this specification.
