Description

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

Conventionally, in plant factories and the like, plant cultivation that combines artificial light lighting and hydroponics has been carried out. Since temperature control of the cultivation area is indispensable for such plant cultivation, there is a problem that heat radiation from the lighting device used for artificial light lighting raises the temperature of the cultivation area. As one of the countermeasures, it is conceivable to use a solid light emitting element such as an LED having a relatively high energy efficiency in the lighting device to suppress the amount of heat generated by the lighting device.

Japanese Unexamined Patent Publication No. 2014-023497 JP-A-2017-6052

However, even in a lighting device having relatively high energy efficiency, about 70% of the energy is generally radiated as heat, so that the amount of heat generated from the lighting device cannot be ignored. Also, the light emitted from the lighting device is used for photosynthesis of plants very little, and most of it is finally converted into heat.

On the other hand, the humidity of the cultivated area also increases due to the evaporation of water from the plants, but if the humidity becomes too high, the transpiration will not proceed, the amount of water sucked up by the cultivated plants will decrease, and eventually growth inhibition will occur. Become.

That is, when cultivating plants in a closed space such as a plant factory, an air conditioning system is indispensable to prevent the space from being filled with hot and humid air.

Patent Document 1 shows an example of such an air-conditioning system, in which air is circulated by installing a fan in order to make the temperature and humidity in a wide cultivation area uniform, but a narrow cultivation shelf. It is difficult to circulate the air evenly between the two.

Further, as in the air conditioning system described in Patent Document 2, if a reflector is provided on the shelf to prevent the lighting from leaking, air stagnation is likely to occur. Therefore, a fan is placed on each shelf to obtain the maximum wind speed. Measures such as using a large fan are required, but such measures are a factor in increasing costs. In addition, when the wind speed is suppressed in consideration of the influence on the growth of plants, for example, effective air circulation may not be possible unless fans are installed at regular intervals, and an increase in the number of fans reduces space efficiency. Will also be invited.

The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is a plant cultivation apparatus and a plant cultivation method capable of improving air-conditioning control necessary for plant cultivation and improving space efficiency. Is to provide.

In order to achieve the above object, the plant cultivation device according to the present invention conveys a plurality of lane bodies arranged at intervals in the vertical direction, a ventilation pipe having a ventilation path formed inside, and a cultivation bottle. A transport device, a lighting device for irradiating the cultivation bottle with light, and a blower device that is communicatively connected to the vent passage, and a vent that communicates with the vent passage is formed on the outer surface of the vent pipe. The vent communicates with the space above the lane body (claim 1).

In the plant cultivation apparatus, a plurality of the lane bodies are three-dimensionally arranged at intervals in both the vertical direction and the horizontal direction, and at least one of the horizontal interval and the vertical interval is set. It may be non-uniform (claim 2).

In the plant cultivation apparatus, the lane body may be inclined so as to be lowered from one end side to the other end side (claim 3).

In the plant cultivation device, the cultivation bottle may be configured to move in the transport direction by utilizing its own weight (claim 4).

In the plant cultivation apparatus, the area and / or density of the vent may be increased as the distance from the portion of the vent pipe connected to the blower increases (claim 5).

On the other hand, in order to achieve the above object, the plant cultivation method according to the present invention cultivates a plant using the plant cultivation apparatus according to any one of claims 1 to 5 (claim 6).

INDUSTRIAL APPLICABILITY According to the present invention, a plant cultivation apparatus and a plant cultivation method capable of satisfactorily controlling air conditioning necessary for plant cultivation and improving space efficiency can be obtained.

That is, in the plant cultivation device of the invention according to each claim of the present application, by operating the ventilation device, the air vapor whose temperature has risen due to the heat radiation of the lighting device and the water vapor derived from the plants held in the cultivation bottle are emitted to the lighting device. It is possible to suck in air from a vent near the plant or to the outside through a vent, or to expel low-temperature, low-humidity air from the vent, which causes large unevenness in the temperature distribution and humidity distribution in the cultivation area. It is easy not to let it occur, and the air conditioning control required for plant cultivation can be performed very well.
Here, when air is sucked in from the vent and discharged to the outside, it is preferable to arrange the vent above the plant held in the cultivation bottle so that warm air can be mainly discharged. On the contrary, when the cold air is discharged from the vent, it is preferable to discharge the cold air from below the plant. Then, for example, it is possible to provide both a ventilation path that sucks air from the ventilation port and discharges it to the outside, and a ventilation path that discharges air from the ventilation port.

Further, since it is possible to adopt a structure that is not large and bulky for the ventilation passage and the ventilation port for performing this air conditioning management, it also contributes to the improvement of space efficiency.

Further, in the plant cultivation device of the present invention, since the vent on the outer surface of the ventilation pipe communicates with the space above the lane body, the temperature rises due to the heat radiation of the lighting device when the blower is not operating. It is not hindered from the upward flow of the air, and the formation of such an air flow makes it difficult for a large rise in temperature and humidity around the plant to occur immediately, which is the operation of the blower. It can also lead to improvement of air conditioning energy efficiency by shortening the time. Then, this effect also tilts the lane body and causes the air flow to move upward along the slope in the space below the lane body and in the ventilation path, as in the plant cultivation apparatus according to claim 3. It can be further enhanced by making it more likely to occur.

Here, when cultivating a plant, for example, continuously from the initial stage of its growth in one plant cultivation device, a plurality of lane bodies are spaced apart in both the vertical direction and the horizontal direction in order to improve space efficiency. It is conceivable that the horizontal spacing and the vertical spacing are non-uniform in the three-dimensional arrangement. Further, in the conventional air conditioning system, if the shelves are arranged in a coarse and dense manner, the air flow tends to be stagnant especially in the area where the shelves are dense, and the air conditioning management tends to be hindered. In the plant cultivation device, since the vent is provided in the ventilation pipe extending along the lane body, even if the lane body and the ventilation pipe are arranged unevenly, the air flow is blocked especially in the area where the lane body and the ventilation pipe are densely packed. It is possible to avoid inconveniences such as facilitation.

In the plant cultivation apparatus according to claim 4, the energy required for transporting the cultivation bottle 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 in the device can be suppressed, and the more the environment in the device suitable for the growth of cultivated plants can be easily maintained.

In the plant cultivation apparatus according to claim 5, the amount of air sucked in or discharged from the vent can be made uniform, which contributes to further improvement of air conditioning management.

It is a top view which shows the main part of the modification of the plant cultivation apparatus of this invention.

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

In the plant cultivation device 1 of this example, as shown in FIGS. 6 to 8, a plurality of lane bodies 3 (for example, 9 or more) are arranged three-dimensionally at intervals in both the horizontal direction and the vertical direction. , A partition wall or the like is not provided so that the spaces around the lane main bodies 3 arranged in this way communicate with each other.

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 is a cultivation bottle holding a plant (shown). In addition to the lane body 3 in which the longitudinal direction X is arranged in the direction of transporting (not) and the ventilation path 2 is formed inside, the transport for transporting the cultivation bottle along the longitudinal direction X of the lane body 3. The device 4 is provided with a plurality of lighting devices 5 arranged on the lower surface of the lane main body 3 to irradiate the cultivation bottle with cultivation light and thermally closely connected to the forming portion of the ventilation path 2. That is, the plant cultivation device 1 is capable of appropriately irradiating the plants held in the cultivation bottle with light from the lighting device 5 and transporting the cultivation bottle by the transport device 4.

The ventilation path 2 is a flow path formed so as to hollow out the inside of the lane body 3 formed of a metal having excellent thermal conductivity such as aluminum, and on the upper surface thereof, for example, from one end side 3A in the longitudinal direction of the lane body 3. A plurality of intake ports (an example of ventilation ports) 2A are formed at intervals from the other end side 3B.

The intake port 2A preferably has a mechanism for preventing the intrusion of foreign matter such as dust. For example, the intake port 2A may be formed by forming a large number of fine holes or a labyrinth structure in the lane body 3. , 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 transport device 4, so that the cultivation bottles or cultivation bottles arranged on the lane body 3 can be detachably attached and detached. It supports a holding body (such as a plate or a hanging basket) to be held so as to be movable in the longitudinal direction X. The transport device 4 of the present embodiment is formed with, for example, a drive mechanism (motor) 4A for supplying a driving force to a roller which is a key point, 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 a wire around the roller. The drive mechanism 4A is preferably provided on the side where the cultivation bottle transfer mechanism 10 described later does not exist.

Further, as shown in FIGS. 6 and 8, each lane body 3 is inclined so as to be lowered from one end side 3A to the other end side 3B, and a force for moving the lane body 3 in the transport direction by the weight of the cultivation bottle itself is applied. It is designed to be generated.

The lighting device 5 preferably emits light having a wavelength suitable for growing cultivated plants to be cultivated. For example, solid-state light emitting elements such as LEDs, OLEDs, and lasers, fluorescent tubes, mercury lamps, and rare lamps. 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 the present invention is not particularly limited thereto. However, from the viewpoint of high luminous efficiency, it is preferable to use a solid-state light emitting element such as an LED, an OLED, or a laser as the lighting device 5. The lighting devices 5 may be distributed on the lower surface of the lane body 3 or continuously arranged in the longitudinal direction thereof, for example, and the number of the lighting devices 5 may be increased in consideration of cultivation efficiency, energy efficiency, and the like. You just have to decide the arrangement. Further, in order to make the thermal connection with the lane main body 3 close, the lighting device 5 may be attached to the lane main body 3 via, for example, heat-dissipating silicone having excellent insulation and thermal conductivity. ..

Further, as shown in FIG. 5, the plant cultivation device 1 applies the heat of the lighting device 5 to the plant cultivation device by using the air taken in from the intake port 2A connected to the ventilation path 2 on one end side of the ventilation path 2. 1 A suction pump is provided as an exhaust device (an example of a blower) 6 for discharging to the outside. In addition, the control circuit 5A that irradiates the lighting device 5 with the cultivated light of an appropriate intensity (adjusts the light intensity) by supplying the adjusted power to the lighting device 5 is as hot as possible with the lane body 3. It is arranged in a physically isolated position so that the heat generated from the control circuit 5A is not diffused into the device.

Further, as shown in FIGS. 6 to 8, the plant cultivation device 1 includes a cultivation bottle transfer mechanism 10 for transferring the cultivation bottle to and from the transfer device 4 at the end of the lane body 3. The cultivation bottle transfer mechanism 10 of the present embodiment transfers (carries) the cultivation bottle to the transport device 4 or the holding body 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 transport device 4. A carry-in mechanism 10A that holds the holding body so that it can be moved, and a carry-out mechanism 10B that transfers (carries out) the cultivation bottle that has moved on the lane body 3 at the other end side 3B of the lane body 3. A transfer means 10C for transporting the cultivation bottle transferred to the carry-out mechanism 10B to one end side 3A of another lane main body 3 is provided.

As is clearly shown in FIG. 7, the lane main body 3 is three-dimensionally arranged in both the horizontal direction and the vertical direction at intervals according to the growth of the cultivated plants mounted on the cultivation bottles. That is, for example, in the initial stage where the plants mounted on the cultivation bottles have not yet grown, the cultivation bottles are mounted on all the lane bodies 3 formed by arranging 6 rows in the horizontal direction provided at the bottom to maximize the space. Cultivation that makes full use of it can be carried out.

Next, when the plant grows to some extent, the plant is grown by sequentially using the lane main bodies 3 formed by arranging 5 rows in the horizontal direction as shown in the 2nd to 4th stages from the bottom, and further, when the plant grows. As shown in the 5th to 9th stages from the bottom, plants can be further grown by sequentially using the lane bodies 3 formed in four rows in the horizontal direction.

That is, since the distance between the horizontal direction and the vertical direction in which the lane body 3 is provided is adjusted according to the growth of the cultivated plant, when the cultivation bottle is moved to the lane body 3, the cultivation bottle is put into the growth stage of the plant. It can be moved to another transport device 4 of the lane main body 3 according to the situation. Then, as the distance between the cultivated plant and the lighting changes as the lane body 3 of the cultivated bottle moves, the cultivated plant can be appropriately irradiated with light of an appropriate intensity required by the cultivated plant. By arranging the horizontal and vertical intervals of the lane body 3 in at least three stages, it is possible to sufficiently cope with the growth of the cultivated plant and the configuration of the plant cultivation device 1 becomes unnecessary. It doesn't get complicated.

Here, it is conceivable to provide an air-conditioning means (air conditioner) for air-conditioning the cultivation area in which the plant cultivation device 1 is arranged, and the air-conditioning means can control at least one of the temperature and humidity of the cultivation area. Those are preferable, and examples thereof include, but are not limited to, an absorption refrigerator, an electric refrigerator, a heat pump chiller, and a desiccant type air conditioner.

According to the plant cultivation method using the plant cultivation device 1 configured as described above, by operating the exhaust device 6, the air whose temperature has risen due to the heat radiation of the lighting device 5 and the water vapor derived from the plant P and the like can be removed. It can be sucked from the 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 large unevenness in the temperature distribution and the humidity distribution in the cultivation area. , The air conditioning control required for plant cultivation can be performed very well. Moreover, when air-conditioned air is supplied to the cultivation area by, for example, an air conditioner, the air-conditioned air is provided between the adjacent lane bodies 3 by providing the intake port 2A at an appropriate position of the lane body 3. It can be drawn firmly into a crowded space, etc., and air conditioning can be managed evenly and reliably throughout the cultivation area.

Further, the ventilation passage 2 and the intake port 2A for performing the air conditioning management can be provided in the lane main body 3 and are not large and bulky, which contributes to the improvement of space efficiency. The effect of improving the space efficiency is further achieved by providing the lane body 3 with a function of holding the transport device 4 and the lighting device 5 and eliminating the need for a configuration in which the transport device 4 and the lighting device 5 are separately held. Can be enhanced. Desirably, the ventilation path 2, the intake port 2A, the transport device 4, and the lighting device 5 are integrated into 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 growing environment of the cultivated plants can be properly maintained, and more plants can be cultivated.

Further, as described above, the lane body 3 is formed of a material such as metal having excellent thermal conductivity, a ventilation path 2 is provided inside the lane body 3, and the lane body 3 holds the lighting device 5, especially the lighting device. If the 5 is thermally closely connected to the lane body 3, the illuminating device 5 that dissipates heat can be efficiently cooled, and further simplification of air conditioning management can be expected.

On the other hand, in the plant cultivation device 1 of this example, the intake port 2A on the outer surface (upper surface) of the lane body 3 communicates with the space above the lane body 3, so that when the exhaust device 6 is not operating, The heat radiation of the lighting device 5 does not prevent the air whose temperature has risen from flowing upward, and the formation of such an air flow makes it difficult for the temperature and humidity around the plant P to rise immediately. Therefore, this can lead to improvement of air conditioning energy efficiency by shortening the operating time of the exhaust device 6. Then, this effect is due to the fact that the lane body 3 is tilted as described above, and the air flow that tends to move upward along the tilt is easily generated in the space below the lane body 3 and in the ventilation path 2. , Will be further strengthened.

Moreover, if the lane body 3 is provided with an inclination so that the cultivation bottle moves in the transport direction by utilizing its own weight, it is not necessary to provide a drive mechanism 4A or the like in the transport device 4, and the configuration is simplified. You can also plan.

On the other hand, in the plant cultivation device 1 of this example, the plant P can be cultivated continuously in one plant cultivation device 1 from the initial stage of its growth, for example, and in order to improve the space efficiency, a plurality of plants P can be cultivated. In order to arrange the lane main body 3 three-dimensionally with an interval in both the vertical direction and the horizontal direction, the interval in the horizontal direction and the interval in the vertical direction are non-uniform. Here, in the conventional air-conditioning system, if the shelves are arranged in a coarse and dense manner, the air flow tends to be blocked, especially in the area where the shelves are dense, and the air-conditioning management tends to be hindered. In the cultivation device 1, since the intake port 2A is provided in the lane main body 3, even if the arrangement of the lane main body 3 is uneven, it is possible to avoid the inconvenience that the air flow tends to be blocked especially in the region where the lane main body 3 is dense. Can be done.

By the way, in this example, a plurality of intake ports 2A are formed at intervals from one end side 3A to the other end side 3B of the lane body 3, but the plurality of intake ports 2A have the same dimensions and are provided at equal intervals. In this case, the amount of air sucked in the intake port 2A near the portion connected to the exhaust device 6 in the lane main body 3 is large, and the amount of air sucked from the intake port 2A decreases as the distance from the intake port 2A increases. Therefore, it is preferable in terms of air conditioning management that the area and / or density of the intake port 2A is increased as the distance from the portion of the lane body 3 connected to the exhaust device 6 increases to make the suction amount uniform. In the examples of FIGS. 1, 2, and 5, the intake port 2A is set to be larger toward one end side 3A.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

The cultivation bottle may hold one plant P or may hold a plurality of plants P. When a plurality of plants P are retained, the number of plants P may be 100 or less, 50 or less, 20 or less, and 10 or less. In particular, when the plant P is small, it is preferable to hold (set) a plurality of plants in one cultivation bottle. Further, the size of the cultivation bottle is considered to be 5 types or less, preferably 3 types or less, and may be only 1 type. Here, the difference in dimensions of ± 20% or less is included in one type.

Further, the cultivation bottle accommodates at least nutrient solution (and / or water) in addition to plant P, and the plant cultivation apparatus 1 provides a station for supplying nutrient solution (and / or water) to the cultivation bottle. It may be provided so that the transport device 4 can carry out the transport to this station.

In the above example, the example in which the drive device 4A is provided in the transfer device 4 is shown, but this may be omitted and the transfer using the own weight of the cultivation bottle may be performed (in this case, the transfer device 4 may be used. It may be composed of rotating bodies such as rollers and wheels). On the contrary, the drive device 4A may be provided on each roller and the lane body 3 may be horizontally arranged for transportation by the drive device 4A.

Here, the individual transportation of the cultivation bottles by the transfer device 4 can be performed only by placing the cultivation bottles at appropriate intervals, for example, when the transfer device 4 is a horizontal conveyor, and in addition, the cultivation bottles fall down. A guide mechanism may be provided so as not to be present. Further, when the lane body 3 is inclined and the transport device 4 transports by the own weight of the cultivation bottles, the cultivation bottles may be packed and transported, but for example, a spacer is provided in the cultivation bottle itself. Alternatively, the size of the holding body such as a plate that holds the cultivation bottles detachably may be appropriately set so that the distance between the adjacent cultivation bottles can be adjusted. Further, the holding bodies that hold the cultivation bottles detachably may be separated from each other at appropriate intervals so that the holding bodies can move. In any case, when the cultivation bottle is transported alone, for example, the cultivation bottle transfer mechanism 10 only needs to be configured so that the cultivation bottle can be delivered to and from the transport device 4, but the cultivation bottle holds it. When the cultivation bottle is detachably held and transported by the body, for example, the cultivation bottle transfer mechanism 10 needs to be provided with a mechanism for attaching / detaching the cultivation bottle to / from the holding body.

Further, the cultivation bottle is not limited to the one that moves 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. Then, when the cultivation bottle is directly hung, for example, it is conceivable to provide a flange on the cultivation bottle and hang it using this flange. Of course, a retainer capable of holding the cultivation bottle in a suspended state may be provided, and the retainer may be conveyed by the transfer device 4.

Then, a plurality of transport methods may be combined, or the cultivation bottle may be transported using a holder capable of realizing the plurality of transport methods. For example, FIG. 9 includes a transport surface 11 that is transported on the transport device 4, and another cultivation bottle B can be detachably attached to the lower surface of the lane body 3 that supports the transport device 4 below the lighting device 5. A recess 12 that can be held in the recess 12 is formed, and the cultivation bottle B can be placed on the transport surface 11 and can be moved in the transport direction X (see FIG. 1 and the like) of the lane body 3 with the cultivation bottle B held in the recess 12. A hanging car body (an example of a holding body) 13 is shown, and transportation using such a hanging car body 13 is also possible. In the case of this example, the dimensions such as the width W and the height H of the hanging 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. Further, the hanging car 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 recess 12, the recess 14 on which the cultivation bottle B can be detachably held is formed on the upper surface of the transport surface 11, but the recesses 12 and 14 are not provided for cultivation. The bottle B may only be placed on the upper portion (transport surface 11) and the lower portion of the hanging car body 13, respectively. In either case, the upper part (transport surface 11) and the lower part of the hanging car body 13 are at least one side in the left-right direction (the direction orthogonal to the transport direction X in the plan view) as shown by the arrow Y, 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 according to 10. Alternatively, as shown by the arrow Y', the hanging car body 13 may be removable from the transport device 4, for example.

FIG. 10 is a plan view showing a modified example of the plant cultivation apparatus of the present invention. As shown in FIG. 10, by bending the lane body 3'in a substantially U shape and bringing the positions of the one end side 3A and the other end side 3B closer to each other, one of the lane bodies 3'is used as the cultivation bottle transfer mechanism 10'. The cultivation bottle B may be configured so that it can be transferred / detached only on the side of. The lane body 3 is not limited to a straight line or a U-shape in a plan view, and may take various forms such as a zigzag shape and a spiral shape.

Further, in order to enable the cultivation bottle transfer mechanism 10 to be provided only on one side of the lane body 3, the transport device 4 may be configured so that the cultivation bottle can be reciprocated along the lane body 3, or the lane body 3 may be reciprocated. It is also conceivable to configure a plurality of cultivation bottles that have reached the opposite side of the above to be returned to one side at a time.

In the above example, one ventilation passage 2 is provided inside the lane body 3, but a plurality of ventilation passages 2 may be provided. In this case, for example, an intake port 2A communicating with each ventilation passage 2 is provided. You may try to make them different.

Further, in the above example, the lane main body 3 also serves as a ventilation pipe having a ventilation passage 2, but a ventilation pipe having a ventilation passage 2 may be provided separately from the lane main body 3, and in this case, the ventilation pipe is a lighting device. It is preferable to provide it on the back side of 5 (a position that does not interfere with the light irradiation by the lighting device 5), but for example, when the light irradiation direction of the lighting device 5 or the position of the ventilation pipe changes with time, the lighting is temporarily or constantly. A ventilation pipe may be provided so as to be located on the front side of the device 5 (a position that hinders light irradiation by the lighting device 5).

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

Further, 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, and may be, for example, a side surface or a lower surface, and may be provided on a plurality of surfaces. It may be. Further, in the example of FIG. 1 and the like, a plurality of intake ports 2A are provided, but for example, only one slit-shaped intake port 2A connecting these may be provided. In this case, for example, the width of the slit may be increased. It is conceivable that the lane body 3 (vent pipe) becomes larger as the distance from the portion connected to the exhaust device 6 increases.

In the above example, the ventilation passage 2 (vent pipe 3), the transfer device 4, and the lighting device 5 are arranged along the lane body 3, but the present invention is not limited to this, and for example, any one or more of them is used. May be provided so as to be along a direction different from the extending direction of the lane body 3.

Needless to say, the modifications given in the present specification may be combined as appropriate.
