Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant-interval-adjustment type transplanter, a method for operating the plant, and a cultivation panel, which can be used in a plant factory for automating cultivation of agricultural products.

[0002]

BACKGROUND ART In the agricultural field, mechanization has been conventionally achieved by introducing various agricultural machines, but further labor saving and improvement of working environment have been demanded against the background of labor shortage in recent years. On the other hand, there is an increasing demand for high-quality crops with low pesticides from the viewpoint of environmental hygiene. As a response to such a demand, a plant factory that hydroponically cultivates crops in a building shielded from the outside world has been attempted. In such a plant factory, the influence of pests can be eliminated by shutting off from the outside, and the influence of pests in soil can be eliminated by hydroponics, and therefore the amount of pesticide used can be greatly reduced. Also,
Since it is cultivated in a building, it is possible to freely set environmental conditions such as internal temperature, humidity, light intensity, and ventilation, and it is also possible to freely set the culture solution for hydroponic cultivation. It enables efficient cultivation and harvesting.

Incidentally, as the hydroponic culture mentioned above, a method of placing a plant strain to be cultivated on a panel or the like and immersing the root extending from the lower surface side in a culture solution stretched in an aquarium has been conventionally used (special feature). See Kaihei 1-137926, etc.). However, the aquarium immersion method requires a large amount of culture solution and is economically problematic. Therefore, in recent years, a method of spraying and supplying the culture solution to the back side of a panel or the like has been used. See Kaihei No. 2-31332, etc.). In addition, in order to make it possible to transport the route from the device that puts the strains on the panel to the device that harvests while cultivating the plant, a transport cultivation device that performs spray cultivation while moving the panel is developed. ing.

[0004] Here, since the strain grows and grows while being transported and cultivated, a sufficient space is required between each strain in order to achieve good growth. However, if the plants are cultivated at intervals between the plants that have been sufficiently grown from the beginning, the space will be wasted when the plants are not grown, and the space efficiency will be reduced. For this,
In recent years, there has been proposed a device capable of changing the stock interval as the stock grows.

As a first method, there is a system in which adjacent strains are conveyed radially and the intervals between the strains are automatically widened as they grow (Japanese Patent Laid-Open No. 940385/1985). (See Sho 61-199734, etc.). As a second method, long and narrow panels in which multiple strains are aligned are installed side by side in the width direction of the cultivation line, and spacers are inserted between the panels as they grow, so that the spacing between rows can be expanded. (See Japanese Patent Laid-Open Nos. 2-276515 and 2-171123, etc.). As a third method, the panel is provided with holes for accommodating the strains at predetermined intervals, and the strains are accommodated in all the holes at the time of non-growth so that the interval between the strains is narrow, and after the growth, every other strain is left, Some other holes have a large space between them, such as by covering with a lid (see Japanese Patent Laid-Open No. 2-195826).

[0006] However, in the above-mentioned first method, each strain has to be transported through a large number of radial transport routes, the apparatus configuration becomes large compared to the number of cultivated strains, and in terms of equipment cost and space efficiency. There is a problem that it is not practical. And
In the above-mentioned second method, although the equipment can be simplified,
There is a problem in that the space can be expanded only in one direction in the transport direction, and it is not possible to expect a sufficient improvement in space efficiency due to expansion in both the vertical and horizontal directions. Further, in the above-mentioned third method, although high space efficiency can be obtained by bidirectional expansion, it is necessary to put in and take out every other stock, and it is necessary to perform work such as covering open holes. There was a problem that improvement of work efficiency could not be expected.

In order to solve such a problem, the applicant of the present application has proposed a stock-spacing-adjustment-type transport cultivation method in which a stock interval is expanded by using a plurality of cultivation panels having different stock intervals. In this method, the strains are housed in a cultivation panel with a small spacing between the plants at the previous stage and transported and cultivated, and the strains are taken out from the panels of these preceding stages and transplanted to a cultivation panel at the subsequent stage with a large spacing between the cultivation stages, By carrying and cultivating in, the expansion of the stock interval between the front and rear stages is realized. Therefore, it is possible to simplify the device and improve work efficiency with good space efficiency.

[0008]

By the way, in the above-mentioned strain interval adjustment type transport cultivation method using a plurality of cultivating panels, the strain is extracted from the cultivating panel having a small strain interval,
When transplanting to a cultivation panel with a large plant spacing, the plant spacing expansion operation is performed. This expansion can be carried out by transferring each strain one by one, but this would result in low work efficiency, and therefore a device capable of transplanting a plurality of strains together is required. Further, when transplanting a plurality of strains together, it is necessary that the strains placed on the panel of the subsequent stage match the strain interval of the panel, and a device capable of adjusting the strain interval at the same time when transplanting is required. Become.

However, when cultivating leafy vegetables, the leaf portion of the strain is the main part of the product. Therefore, it is not possible to use a device that grips the entire leaf portion of the stock. Therefore, it is desired to develop a device capable of avoiding damage to the leaves and simultaneously transplanting a plurality of strains while adjusting the intervals. Then, the device for simultaneous transplantation while adjusting the intervals of such a plurality of strains is not limited to the above-described hydroponic-type strain-based cultivation, and another treatment is performed by taking out the strains from the panel during other cultivation or harvesting. It was also required when rearranging to do. An object of the present invention is to provide a plant-interval-adjustment-type transplantation device capable of avoiding damage to leaves and simultaneously transplanting a plurality of plants while adjusting the intervals, a method for operating the plant, and a cultivation panel.

[0010]

The device of the present invention is a plant-interval-adjusting transplanter for taking out strains arranged in a state where the inter-plant spacing is narrow and transplanting the plants in a wide inter-plant spacing condition. It is characterized by including a support capable of supporting the root portion of the strain and the in-row spacing adjusting means capable of adjusting the spacing between the respective strains supported by the support. In such a configuration, the efficiency of work can be improved by collectively transplanting a plurality of rows for one row by the support, and the spacing of the stock for one row supported by the intra-row spacing adjusting means is adjusted. At this time, the interval adjustment may be performed linearly for one row of stocks,
The structure and operation can be simplified. The support may include a pair of rail members that support a row of stocks from both sides. As a result, the rail member is extended so as to pass through both sides of the root portion of the plant, whereby one line of the plant can be supported, and damage to the leaf portion of the plant can be avoided when supporting.

Further, the in-row space adjusting means is an engagement member which is arranged along the support and is engageable with each stock supported by the support and movable in the row direction of the stock.
And a coupling mechanism that automatically couples the engaging members so that the distance between them is the same.
As a result, the stocks can always be arranged at equal intervals, and the above-mentioned in-row space adjustment can be easily and reliably performed. Also,
The engagement member can be retracted from a position in which the stock is supported by the support to a position in which the stock does not interfere with the stock. As a result, it is possible to avoid damage to the leaves or roots of the plant due to the engaging members for adjusting the in-row spacing.

Further, a plurality of the in-row space adjusting means are arranged in parallel in the row direction, and the tips of the in-row space adjusting means are connected to each other by a connecting bar arranged below the engaging member. This makes it possible for the in-row spacing adjustment means to correspond to the stocks in each row and to facilitate the operation to be introduced between the stocks, and to maintain the in-row spacing adjustment means in each row in parallel with each other, which is stable. It is possible to perform the operation that has been performed.

Further, there is provided an inter-row spacing adjusting means having a plurality of the above-mentioned supports arranged in parallel and a connecting mechanism for connecting the supports so that the intervals between them are automatically the same. And With such a configuration, it is possible to collectively transplant a plurality of rows of strains, such as one cultivation panel, and further improve work efficiency, and it is possible to simultaneously perform two-way spacing adjustment within and between rows. .
Further, the connection mechanism is formed of a pantograph type link. This makes it possible to easily perform automatic holding at equal intervals in and between rows.

In the method for operating the plant-interval-adjustment-type transplantation device of the present invention, when the inter-row spacing adjusting means and / or the inter-row spacing adjusting means is adjusted to a predetermined spacing, the spacing is once set to the predetermined spacing. It is characterized in that it is expanded as described above and then the interval is reduced to match the predetermined value interval. By doing so, for example, even when the distance adjustment amount is small, the operation amount becomes large, and it is possible to eliminate the movement error caused by the sliding resistance and the like and perform the distance adjustment reliably. When the strain supported by the support is placed on the portion to be transplanted, the support is lowered to the portion to be transplanted, once raised, and then lowered again to place the strain. It is characterized by By doing this, when the strain is placed on the part to be transplanted, even if the strain does not fit well in the desired posture, it can be reliably put in again by descending and stable operation is possible. Becomes

The cultivating panel of the present invention is characterized in that it has a large number of stock holes arranged on the surface thereof, and that guide grooves for holding and guiding the support are provided along each row of these holes. To do. In such a configuration, the support will be placed along the panel surface and guided prior to lifting the stock and installed in the desired condition along the stock. Therefore, it is possible to perform a reliable transplanting operation and also to avoid damage to the leaf portion of the strain.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of a plant factory 10 to which the present invention is applied. FIG. 2 shows a work process in the plant factory 10. In FIG. 2, the plant factory 10 of the present example is for manufacturing leafy vegetables such as spinach and salad vegetables, and mainly focuses on a cultivation process in which a culture solution or the like is spray-supplied and grown while the strain is housed in a panel and conveyed. First, each step of sowing, raising seedlings, and fixed planting is performed, and then the harvesting step is performed.

(Seeding Step) The seeds 20 of leaf vegetables to be produced are settled on a seedling raising mat 21 which serves as a nursery bed. The seedling-growing mat 21 is a sponge-like material having a water-absorbing property, and is preliminarily provided with a cut 21A.
Are formed and partitioned in a grid shape, and can be separated by pulling them away from each other. An adhesive for fixing the seed 20 is applied to the surface of each section. (Seedling raising step) The seeded raising seedling mats 21 are accommodated in a tray or the like and hydroponically cultivated, and seeds 20 are germinated to be raised as seedlings 22. (Planting process) The seedlings 22 raised by the seedling mat 21 are cut 21
By separating from A, each seedling block 23 is divided into strains 24. Then, the individual strains 24 are housed in the cultivation cup 25, and the cultivation cup 25 is placed on the cultivation panel 26.

(Cultivation Step) The cultivation step is divided into first to third stages, in each of which the strain 24 is transported and cultivated using three kinds of cultivation panels 26 to 28 of small, medium and large. Between each stage, the strain 24 on the cultivation panels 26, 27 of the previous stage is sequentially transferred to the cultivation panels 27, 28 of the next stage together with the cultivation cup 25 by the first and second transplantation. In each cultivation panel 26-28 to which the strain 24 is transferred, the mutual spacing of the holes 26A to 28A for accommodating the strain 14 is made larger as the later one, and the strain 24 sent to each stage is suitable for the growth degree. Cultivated at intervals of plants. (Harvesting Step) Subsequently, the cultivation panel 28 is received from the cultivation step, the roots 29 of the strain 24 are cut off, and the cultivation cup 25 is taken out, and the strain 24 with the seedling block 23 is taken out from the cultivation cup 25 to obtain a product. The product is appropriately packaged and shipped.

Next, the cultivation cup 25 and cultivation panels 26 to 28 used in the above-mentioned steps will be described. (Cultivation Cup) FIGS. 3 and 4 show a cultivation cup 25 used in this embodiment. The cultivating cup 25 has a tubular main body 250, and the main body 250 is composed of a tapered upper part 251 and a lower part 252, each of which has an expanded upper side.
1 has a larger diameter than the lower part 252. The upper part 251 and the lower part 252 are connected by a substantially horizontal step 253, and the upper opening 254
A substantially horizontal flange 255 is formed on the outer periphery of the.

The bottom surface of the lower portion 252 is formed with a lower surface opening 256 whose inner peripheral edge is curved downward, and the inner periphery of the upper portion 251 is formed with three ribs 257 evenly in the circumferential direction.
And is connected to the step portion 253. here,
The inner edge of the rib 257 is gradually widened downward, and the envelope circle connecting the same height of each inner edge is reduced in diameter as it goes downward. The lower end of each inner edge is continuous with the inner surface of the lower portion 252. These parts 250 to 257 are integrally formed by injection molding a semitransparent synthetic resin material.

(Effect of Cultivation Cup) In the cultivation cup 25 of this embodiment, the seedling block 23 is inserted from the upper surface opening 254, the seedling 22 extends from the upper surface opening 254, and the root 29 extends from the lower surface opening 256. To be done. At this time, the seedling block 23 is tightened by the rib 257 as it is inserted,
Although it is easy to introduce, it does not easily fall off the cultivation cup 25. Furthermore, since the rib 257 is continuous with the inner surface of the lower portion 252, a part of the seedling block 23 can be guided to the inside of the lower portion 252, and more reliable fall prevention can be achieved.

When a mechanical drawing means is introduced from the lower surface opening 256 for inserting the seedling block 23, the inner circumference of the lower surface opening 256 is curved downward, so that the seedling block 23 is sandwiched and the diameter is expanded. Even if it is done, it is easy to pull out. Furthermore, since the step portion 253 and the flange 255 are provided,
The cultivation cups 25 can be supported by each, and they can be easily handed over or handed over by alternately supporting them.

Since the upper part 251 and the lower part 252 are tapered so that the upper side is widened, in this respect also, the seedling block 23 can be easily pulled in and taken out, and the panels 26 to 28 can be removed.
It is easy to insert it when storing it in the
Upper 251 and lower 252 depending on inner diameter setting from A to 28A
It can also be supported in the middle part of. In addition, the upper 251

(Cultivation Panel) FIGS. 5 and 6 show cultivation panels 26 to 28 used in this embodiment. In addition,
FIG. 5 shows a quarter of each of the cultivation panels 26 to 28. FIG. 5 (A) shows the cultivation panel 26 for the first stage, and FIG. 5 (B) shows the cultivation panel 27 for the second stage. 5 (C) shows the cultivation panel 28 for the third stage. Each of the cultivation panels 26 to 28 has a plate-shaped base material 260 made of a styrene resin foam and a large number of holes 26A to 28A penetrating through the front and back sides thereof so that the cultivation cup 25 can be held. At the edges of each cultivation panel 26-28, a reinforcing material 26 having a U-shaped cross section covering from the upper surface to the lower surface.
1 is covered all around. A plurality of ridges 262 are formed in the longitudinal direction on the lower surface and side surfaces of the reinforcing material 261.

In the cultivation panels 26 and 27, the inner diameters of the holes 26A and 26B are larger than the lower portion 252 of the cultivation cup 25 and smaller than the step portion 253, and the cultivation cup 25 is locked by the step portion 253. On the other hand, in the cultivation panel 28, the inner diameter of the hole 28A is the same as the outer diameter of the middle position of the upper portion 251 of the cultivation cup 25, and the cultivation cup 25 is locked in a state where the upper portion 251 is partially retracted. The holes 26A-28A of each cultivation panel 26-28 are
It is arranged in seven long rows 26B to 28B arranged in rows of eight and six short rows 26C to 28C arranged in rows of seven, forming a total of 98 pieces. The holes in the long rows 26B to 28B and the holes in the short rows 26C to 28C are staggered and staggered as a whole.

In each cultivation panel 26-28, the inter-row spacing d261-d281 between the holes in each row and the inter-row spacing d2 between each row.
62-d282, the spacing d261, d262 of the cultivation panel 26 is smaller than the spacing d271, d272 of the cultivation panel 27, and between the cultivation panel 28 and the cultivation panel 27, the row spacing d282 and the row spacing d2.
Same as 72, but in-row spacing d281 is larger than in-row spacing d271. And, assuming that the plant spacing d263 to d283 to the nearest hole of each hole in each cultivation panel 26-28, in the cultivation panel 26, 27 the intra-row spacing d261, d271 is the stock spacing d263, d273.
Therefore, the cultivation panel 27 has a wider spacing than the cultivation panel 26. On the other hand, the plant spacing d283 of the cultivation panel 28 is generated between the holes of the adjacent rows and is smaller than the intra-row spacing d281, but is wider than the plant spacing d273 of the cultivation panel 27.

(Effect of Cultivation Panel) In the cultivation panels 26 to 28 of this embodiment, the strain 24 is added to each cultivation panel 26 in the cultivation process.
Sequential transplantation to ~ 28 allows the plant interval to be gradually expanded as the plant grows, and an appropriate cultivation environment can be obtained while improving space efficiency. In particular, the cultivation panel 26,
Between 27, the use of panels of different vertical and horizontal dimensions allows for greater intra-row and inter-row spacing and two-dimensional extension of the stock spacing. In addition, since the staggered arrangement is used between the cultivation panels 27 and 28, it is possible to two-dimensionally expand the stock spacing only by expanding the intra-row spacing. Therefore, cultivation panels 27,28
Can have the same width but different depth,
It is also possible to share the transportation mechanism and the like in the cultivation process.

Further, since the reinforcing material 261 is provided all around,
It is possible to prevent damage caused by handling the cultivation panels 26 to 28, and to secure the load strength when the plant 24 is placed. Further, since the ridges 262 are provided on the reinforcing material 261, it is possible to reduce the frictional resistance when the both sides are slidably guided by the guide rails and conveyed in the cultivation process. Further, since the reinforcing material 261 and the base material 260 are separated from each other, a strip-shaped metal reinforcing plate can be sandwiched along the end surface of the base material 260 inside the widthwise reinforcing material 261 as necessary. It is possible to further increase the load strength when supporting both sides during transportation in the cultivation process.

(Effects of the cultivating apparatus of the present embodiment) In the cultivating apparatus 14 of the present embodiment, transport cultivation is performed while expanding the interval between the stocks at each of the first to third stages, so that space efficiency is improved. Appropriate strains 24 can be cultivated and the harvesting efficiency can be improved. In particular, in expanding the plant interval, using the cultivation panels 26 to 28 in which the plant interval gradually expands to the first to third stages, the plant interval was expanded when transplanting between each stage, so that the bidirectional It is possible to easily and surely extend the stock interval.

Further, since the numbers of the strains 24 on one of the cultivation panels 26 to 28 are set to be the same and the strains of each panel are collectively transplanted at the time of transplantation, the working efficiency can be improved and the interval between the strains can be easily expanded. It can be carried out. Furthermore, in transplanting between each stage, by processing from the rear stage to the front stage in order, the spacing machine 19 takes out the strain 24 from the cultivation panel 26, 27 at the exit of the previous stage and the new cultivation at the entrance of the rear stage. Shares 24 to panels 27, 28
Can be continuously placed, and work efficiency can be improved. Then, by performing the transplant in the order from the later to the previous, all the transplantation can be performed on the cultivation line 16, since the strain 24 does not go out of the range of the cultivation line 16, the strain 24 is not It is possible to avoid inconvenience such as being exposed to a stable situation for a long time, and it is possible to prevent stains and the like around the surroundings due to drops from the stock 24.

In the cultivating apparatus 14 of this embodiment, the respective cultivating lines 16 are arranged in parallel and opposite directions as the feed line 16A and the return line 16B, and each stage is constituted by folding back by the lane shifter 17 on the folding side. The equipment structure can be made compact while securing the stage length. Also, since the panel server 18 and the spacing machine 19 on the loading and unloading side made the three stages continuous,
The stages are arranged in a zigzag manner, which makes it possible to make the equipment configuration more compact. Further, since the folding side and the putting-in side of each stage are matched with each other, the lane shifter 17 of each stage does not interfere with each other on the folding side, and the occupied area can be reduced, and at the putting-in side, the panel server 18 and the spacing machine. 19 can be shared by a plurality of stages, and equipment can be simplified and compacted.

Further, in the cultivating apparatus 14 of the present embodiment, since either one of the feed line 16A and the return line 16B of each stage is arranged in parallel, a larger number of panels can be transported and cultivated on the side of the plurality of lines. The transport time at each stage can be extended, and the stock 24 can be sufficiently grown. In particular, since only one of the feed and return is pluralized, the period during which the seeds are continuously conveyed and cultivated during folding or transplanting can be extended, and the strains 24 can be left standing in the same state for a long time. Can be further improved.

Further, since the conveying speed of a plurality of lines is set to be a fraction of the number of lines with reference to the feeding speed of one line,
The number of panels to be delivered between the feed and return lines can be made equal, and timing adjustment and the like are not required, so that feed control and the like can be simplified. Further, since the lane shifter 17 and the panel server 18 can be moved to perform panel distribution from one line and panel merging from a plurality of lines, it is not necessary to use a dedicated allocating means and merging means for multiple lines. The equipment configuration and control can be simplified.

In this embodiment, since each stage is constructed by using a large number of cultivation lines 16, the same members can be shared and the installation cost can be reduced. Further, by adjusting the number of lines, it is possible to flexibly adjust the scale, cultivation period, and the like. Furthermore, cultivation line 16
Since no drive unit is installed in the lane shifter and the entire panel of each line is moved by extrusion drive by the lane shifter 17 and the panel server 18, the drive mechanism of the lane shifter 17 and the panel server 18 shared by multiple lines can be effectively used. At the same time, it is not necessary to provide a drive mechanism or the like in each of the cultivation lines 16, and the equipment can be simplified.

Next, the cultivation line 16, the lane shifter 17, the panel server 18, and the spacing machine 19 for realizing the above-described cultivation device 14 will be described in detail. (Cultivation Line) FIGS. 8 to 13 show the structure of the cultivation line 16. Figure 8 shows the side of the cultivation line 16,
Figure 9 shows a cross section of the cultivation line 16 for the first stage,

Cultivation line 16 supports a large number of cultivation panels 26 to 28 sent from the inlet side end portion over the entire length, grows each strain 24 by spraying a culture solution or the like from the lower surface side, and from the outlet side end portion. It is something to send out.

The cultivation line 16 has a frame 160 assembled from a shaft material and a wire, and this frame 160 forms a partition part 160A extending in the carrying direction and a bottom part 160B connecting these lower parts. A guide rail member 161 extending in the transport direction is supported on the upper end of the partition 160A and the bottom 160B.
A trough-shaped collection member 162 for collecting the sprayed culture solution is installed along the center line. Collection member 162
A supply pipe 16 for pumping the culture solution along the transport direction inside the
3 is supported, and a spray nozzle 164 for spraying the culture solution upward is installed at predetermined intervals. A flexible side cover 165 made of a synthetic resin sheet is stretched from both sides of the recovery member 162 to the guide rail member 161.

As shown in FIG. 11, the guide rail member 161 is a synthetic resin molded product by extrusion or the like having guide grooves 161A for receiving the ends of the cultivation panels 26 to 28 on both sides of a central box-shaped structure, The guide groove 161A is formed so as to surround the reinforcing material 261 at the end of the panel from the upper surface to the lower surface, and communication between the front and back of the panel through the relevant portion is blocked. The lower side of the guide groove 161A supporting the panel load is formed to be long, and a sliding contact material 161B having a low friction coefficient is attached to the surface thereof.
Together with the ridges 262, the slidability of the cultivation panels 26 to 28 during transportation is considered to be good. Clips 161C are formed at lower ends of the guide grooves 161A continuously or intermittently in the transport direction. A bar 161D in which the upper end of the side cover 165 is wound is fitted into the clip 161C, whereby the upper end of the side cover 165 is connected to the guide rail member 161.

As shown in FIG. 12, the recovery member 162 is a synthetic resin molded product obtained by extrusion or the like, and has leg portions 162A for fixing the frame formed on both sides of the bottom surface, and a slit having an upward facing shape at the center of the bottom surface. The Y-shaped supply pipe support portion 162B is formed continuously or intermittently in the transport direction. Collection member 162
Clips 162C that are continuously or intermittently wound inward in the transport direction are formed on both upper ends of the clip 162C. This clip 162C is a bar that is wrapped around the bottom edge of the side cover 165.
162D is fitted in, so that the lower end of the side cover 165 is connected to the recovery member 162.

The supply pipe 163 is a synthetic resin molded product formed by extrusion or the like having a cylindrical shape extending in the conveying direction, and has a support rib 163A on the lower surface side and a pedestal portion 163B on the upper surface side continuously or intermittently. Has been formed. The support rib 163A is inserted and engaged with the supply pipe support portion 162B of the recovery member 162, so that the supply pipe 163 is supported at a predetermined position in the recovery member 162. The spray nozzles 164 are screwed and fixed to the pedestal portion 163B at predetermined intervals in an internal communication state, and the culture solution or the like that is pressure-fed and supplied into the supply pipe 163 is sprayed upward from the spray nozzle 164. The spray nozzle 164 has a blade 164A that is rotatably held inside, and the culture solution sprayed upward.
The 164B is designed to have enough space.

As shown in FIG. 13, the recovery member 162 and the supply pipe 163 are formed by appropriately adding pipes of a predetermined length. The recovery member 162 is connected by a joint material 162E having an E-shaped cross section. The joint material 162E is a flexible synthetic resin material or the like. The supply pipe 163 is connected by a joint pipe 163E having an outer diameter substantially the same as its inner diameter.
The joint pipe 163E is made of the same synthetic resin material as the supply pipe 163. The ends of the recovery member 162 and the supply pipe 163 are sealed with cap members 162F and 163F, respectively. These cap materials 162F and 163F have the same end surface shape as the recovery member 162 or the supply pipe 163, and the joint material 162E or the joint pipe 162F.
Connected via 163E.

In the case of the first stage shown in FIG. 9, the side cover 165 is composed of one sheet, and its upper end is locked to the clip 161C of the guide rail member 161, as described above.
The lower end is locked to the clip 162C of the recovery member 162C. At this time, the intermediate portion is stretched through the outside of the intermediate bar 160C supported in the intermediate heights on both sides of the partition 160A of the frame 160 and extending in the carrying direction, forming a so-called home base type. On the other hand, in the case of the second and third stages shown in FIG. 10,
Similarly placed on the home base, but with side cover 165
Is composed of two sheets 165A and 165B. Lower sheet
The upper end of 165B is locked to the intermediate rod member 160C, and the lower end thereof is locked to the clip 162C of the recovery member 162C and is in a tensioned state. The upper seat 165A has a guide rail member 161 at the upper end.
Of the lower seat 16
I just put it along 5B. In addition, each clip 161C, 162C
The portion to be locked with may be simply wrapped around the rods 161D and 162D, but it is preferable to form it in a bag shape in advance. Further, it is desirable that the lower sheet 165B that is locked to the intermediate rod member 160C is also formed in a bag shape so that it can be inserted into the intermediate rod member 160C.

Returning to FIG. 8, the portions below the cultivation panels 26 to 28 on both end surfaces of the cultivation line 16 are sealed with end plates 166, and the space surrounded by the cultivation panels 26 to 28 and the side cover 165 is substantially the same. It is designed to be hermetically sealed. Of the end plates 166, the one facing the lane shifter 17 and the harvesting device 15 is formed with a door 167, and this door 167 can be opened by moving it upward, and when it is opened, the cultivation panels 26 to 28 and their lower parts are opened. The opening area is sufficient to allow the roots of the hanging plant 24 to pass through without fail. An operation lever 167A for opening and closing is formed on the surface of the door 167 so that the lane shifter 17 and the harvesting device 15 can automatically open and close the door.

Of the other ends, the portion facing the planting device 13 does not require the door 167 because the root of the plant 24 is short, and the portion facing the panel server 18 is taken out by the spacing machine 19, etc. Since the cultivation panels 26 to 28 are taken in and out without the stock 24, the door 167 is unnecessary. Also, the supply pipe 16
3 is a part of the cultivation panel 26-28 transplanted by the spacing machine 19 is a supply pipe 163G of a different system from the other parts, and there is no stock 24 in the holes 26A-28A of the cultivation panel 26-28. While it is opened, only the supply pipe 163G can independently stop the pressure feeding of the culture solution.

(Effects of Cultivation Line) In the cultivation line 16 of the present embodiment, the guide rail members 161 support the cultivation panels 26 to 28, and new panels are sent from the lane shifter 17 and the panel server 18 to each panel. Can be sequentially transported. Also, during transportation, the spray nozzle 164
The culture broth can be spray-supplied to the lower surface side of the cultivation panels 26 to 28, whereby the transport cultivation of the strain 24 can be performed.

Further, the substantially U-shaped guide portion 161A of the guide rail member 161 accommodates the end portions of the cultivation panels 26 to 28, and the lower portion of the cultivation panels 26 to 28 is covered with a side cover 165.
By surrounding the end face plate 166 with the end plate 166, it is possible to prevent the sprayed culture solution from leaking out and eliminate waste of the culture solution. Then, add excess culture solution to the side sheet
It is also possible to reuse by collecting from 165 to the recovery member 162. In addition, since the section to be transplanted by the spacing machine 19 is a separate line, the culture solution does not scatter to the outside through the holes 26A to 28A even when the cultivation panel 26 to 28 does not have the strain 24, and the culture solution is wasted. Not only can it be prevented, but surrounding dirt and the like can also be avoided.

On the other hand, the cultivation panel 16 of this embodiment has a simple frame 160 and a guide rail member 161 formed by resin molding.
, Collecting member 162, supply pipe 163, sheet-like side cover 1
Since it is composed of 65 etc., the structure is simple and the manufacturing cost can be reduced, and the cultivation lines 16 having different sizes can be configured by sharing each other. Also, since the guide rail member 161 has the guide portions 161A on both sides, one member can be shared by two adjacent lines, and the connection between the recovery member 162 and the supply pipe 163 is also a insertion type, so the structure is simple. In addition, the installation work can be done easily. In particular, since the side cover 165 for the second and third stages is composed of two sheets 165A and 165B, it is not necessary to use a special wide sheet, and since they are connected by lining each other, the connection is easy. Despite this, sufficient performance can be obtained for blocking the fog and drops of the culture solution.

Further, the side cover 165 is of a so-called home base type so that the culture solution can be smoothly returned to the recovery member 162 and the cultivation panel 26 to
A sufficient space corresponding to the planar shape of 28 can be formed, and even the plant 24 at the peripheral portion of the panel does not interfere with the roots, and good growth can be achieved. Also, the end plate 16
Since the door 167 of 6 is also opened below the cultivation panels 26 to 28, the possibility of damaging the roots of the plant 24 when the cultivation panels 26 to 28 are taken in and out can be eliminated, and good growth can be expected.

(Lane Shifter) FIGS. 14 and 15 show the structure of the lane shifter 17. Lane shifter 17
Includes a substantially box-shaped frame 170 whose planar shape is larger than that of the cultivation panels 26 to 28. The frame 170 is supported by rails 170B via wheels 170A provided on the lower portion, and is movable along all the feed line outlets and the return line inlets of each stage. The rail 170B is continuous from the first stage to the third stage, and is shared by the three lane shifters 17 of each stage. rail

Next, the received cultivation panels 26 to 28 are moved along the rail 170B to the entrance side of the cultivation line 16 and the door 167 of the cultivation line 16 is opened by the opening / closing lever 175. In this state, wait for a signal of completion of preparation from the panel server 18 or the harvesting device 15 on the loading / unloading side, and when the signal is received, the moving member 172 is retracted to push out the cultivation panels 26 to 28, and each panel on this cultivation line 16 is pushed. The panels that are currently being pushed are completely pushed into the cultivation line 16 while sequentially feeding and pushing the panels on the loading / unloading side. When this panel is completely contained in the cultivation line 16, the lane shifter 17
The gripping arm 173 is opened and retracted, the opening / closing lever 175 is lowered, and the door 167 of the cultivation line 16 is closed. As a result, the cultivation panels 26 to 28 are folded back.

(Effect of Lane Shifter) According to the lane shifter 17 of the present embodiment, all the cultivation lines 16 in the corresponding stage can be dealt with by moving along the rail 170B, and the cultivation panels 26 to 28 other than the folding panels 26-28 can be used. Can also be transferred to the line by the transfer. For this reason, when only the panel is moved, the transport mechanism and the like are complicated and large, but the configuration can be extremely simple. Also, since it can be connected to any cultivation line 16,
Panel distribution and merging can be freely performed when there are a plurality of feed lines and return lines.

Further, since the panel pushed out from the cultivation line 16 is pulled in by the gripping arm 173, the panel can be reliably pulled in, and the inconvenience such as catching when moving to another line is surely done. It can be avoided. Further, when the panel is completely taken out, it is supported by the auxiliary supporting member 174, so that the position of the panel can be reliably aligned with the cultivation line 16 when it is sent to another line, and the sending can be performed smoothly. Further, the door 167 of the cultivation line 16 can be automatically opened / closed by the opening / closing lever 175, and the panel folding operation can be completely automated.

Move to. When the cultivation panel 26 is pushed out from the return line 16B, the panel is gradually inserted into the collecting section 186, and the tip is gripped by the gripping arm 185 and retracted by the moving member 183, so that it is completely accommodated in the collecting section 18C. To be done. When the cultivation panel 26 is completely accommodated, the stocker 186 descends by one panel, and the upper surface of the accommodated panel is adjusted to the panel lower surface height of the cultivation line 16.

As a result, panel supply to the second stage and panel recovery from the first stage are sequentially performed.
The panel server 18B for the second and third stages has different types of panels (the collection section 18C has a cultivation panel 27 and a supply section).
18D becomes a cultivation panel 28), but the operation is similar to that for the first and second stages described above, whereby the panel supply to the third stage and the panel recovery from the second stage are sequentially performed.

(Effect of Panel Server) According to the panel server 18 of this embodiment, by moving along the rail 180B, it is possible to correspond to all the cultivation lines 16 on the feeding side of the rear stage and the returning side of the preceding stage, Panel supply and panel recovery for each can be performed. Since the collecting unit 18C and the supplying unit 18D for collecting the panel and supplying the panel are integrated, a moving mechanism and the like for moving each to each line are shared, and the facility structure can be simplified. Further, since the panel to be supplied is preliminarily loaded in the supply unit 18D and the collected panel is loaded and held in the recovery unit 18C, it is not necessary to move to a stocker device or the like at a different position for each supply or recovery, The operation can be performed efficiently. Furthermore, since the panel pushed out from the cultivation line 16 is pulled in by the gripping arm 185, the panel can be reliably pulled in, and inconvenience such as catching when moving to another line can be surely avoided.

The 2L rotates by a predetermined angle, but this angle is regulated by mutual connection. Therefore, the distance between the moving members 192G is always maintained at the same distance by the connecting mechanism 192K. As a result, each moving member 192G is moved via the connecting mechanism 192K with the distance between the moving members 192G at both ends.
It is designed such that the mutual intervals are always the same and are enlarged or reduced. The lower end of each moving member 192G receives the receiving member 19 with which the tip of the stock support rail 193 is engaged.

The rail member 193A has a pair of intervals set to be larger than the outer diameter of the upper portion 251 of the cultivation cup 25 and smaller than the outer diameter of the flange 255, and is supported by each panel by advancing along the cultivation panels 26 to 28. The cultivation cups 25 of the strains 24 are sequentially sandwiched from both sides, and one row can be collectively lifted. The base end side of each rail member 193A is supported by a pair of width-direction guide rails 193E so as to be movable in the width direction, and the guide rails 193E are supported by the base end member 193D in the base 191. The base end member 193D is screwed and supported by a pair of feed screw shafts 193B supported in the base 191 in the transport direction.
Each feed screw shaft 193B is synchronously rotated by a motor 193C provided on the front side (cultivation line 16 side), whereby each rail member 193A is integrally advanced and retracted.

Of the base end side of the rail member 193A, the ones at both ends are screwed to the reverse screw type feed screw shaft 193F, and the motor 193J
They are driven to rotate by and are separated from each other. Each rail member
The base end side of 193A is connected via a pantograph-type connecting mechanism 193K (similar to the connecting mechanism 192K of the above-mentioned tip support arm). As a result, the rail members 193A can be expanded or reduced with respect to each other in a state of being evenly spaced from each other. The tip of the rail member 193A is tapered, and can be inserted and engaged in the hole of each receiving member 192M of the tip support arm 192. In addition, the rail member 193A in the stock support rail 193

192J is controlled in synchronization with each other, and the rail member 193A and the receiving member 192M are movable in the width direction while being engaged and connected to each other. With these stock support rails 193 and tip support arms 192, it is possible to lift the stocks 24 accommodated in the cultivation panels 26 to 28 for each row, and to increase the interval for each row. Is configured.

The rail member 193A is previously formed on the panel surface so that the rail member 193A can be reliably guided when it is extended.
You may form the concave guide groove which can be inserted.
In addition, a plurality of guide members having grooves for guiding the rail members 193A are provided on the cultivation line 16 side of the base 191, and each groove interval is made to correspond to the row interval of the cultivation panels 26, 27 used in the previous stage. Therefore, the interval between the rail members 193A may be regulated before the extension.

(Auxiliary Arm of Spacing Machine) The auxiliary arm 194 has rail members directly below the stock support rail 193.
A total of 13 rod-shaped rail members 194A corresponding to 193A are provided, and the same number of arm members 195A are provided below the rail members 194A. Each arm member 195A has a tip member 195B and a base plate 195C, and each rail member 193A has its tip and base end rotatably supported by the tip member 195B and the base plate 195C. Each base plate 195C includes a pair of widthwise guide rails 194E.
It is supported by the guide rail 19 so that it can move in the width direction.
4E is supported by base end members 194D on both sides inside the base 191. The base end member 194D is screwed and supported by the feed screw shaft 194B in the carrying direction, and is moved forward and backward by the rotational driving of the motor 194C.
As a result, the holding arm 194 is moved back and forth in the transport direction as a whole.

Of the base plate 195C, those at both ends are screwed onto a reverse screw type feed screw shaft 194F and are driven to rotate by a motor 194J so as to be separated from each other. The base plates 195C are connected to each other via a pantograph-type connecting mechanism 194K (similar to the connecting mechanism 192K of the tip support arm described above). As a result, the base end plates 195C or the arm members 195A and the rail members 194A can be enlarged or reduced in the mutual intervals in the state of being evenly spaced from each other.

A plurality of moving members 194G are arranged at predetermined intervals on each rail member 194A. The number of the moving members 194G corresponds to the number of the strains 24 in the corresponding rows of the cultivation panels 26 to 28, and is 8 and 7 alternately. As shown in FIGS. 23 and 24, the moving member 194G is a substantially U-shaped member formed by bending a plate material, and each rod-shaped rail member 194A is inserted through circular insertion holes formed on both sides of the U-shape. And rail member 194A
It is movable and rotatable along. Each moving member 194G
A substantially U-shaped engaging member 194M is disposed on the inside of this, and this engaging member 194M is capable of inserting and engaging the cultivation cup 25 on the inside of the U-shape and at the square hole formed on the base end side. Rail member
It has been penetrated through 194A. As a result, a spline fitting is formed, the engaging member 194M is rotated according to the rotation of the rail member 194A, and is movable along the rail member 194A according to the movement of the moving member 194G. In addition, rail member
The rotation of 194A is performed by a drive source 195N such as a solenoid provided on the base plate 195C.

The lower part of each moving member 194G is connected via a pantograph type connecting mechanism 194K. Connecting mechanism 194K
Is a series of a number of so-called parallel link mechanisms, and the upper rotation connecting portion of each link member 194L is a moving member.
It is rotatably supported at the bottom of 194G. Of the moving members 194G, the most distal one is connected to the tip member 195B, and the most proximal one is connected to the transmission rod 194H. Transmission rod 19
4H is moved back and forth in the carrying direction by a motor 194J provided on the base plate 195C, so that the moving members 194G are kept close to each other and are spaced apart from each other. With such an auxiliary arm 194, the stock 24 lifted for each row by the stock support rail 193 can be moved by the engaging member 194M to increase the intra-row spacing, and as described above, the intra-row spacing adjusting mechanism is provided. Is configured.

(Operation of Spacing Machine) In such a spacing machine 19, normally, the base 191 is moved above the frame 190 and the tip support arm 19 is moved.
2. The stock support rail 193 and the auxiliary arm 194 at the bottom are housed in the frame 190. The engaging member 194M of the auxiliary arm 194 is in a state of being tilted downward. In this state, each arm 192, 194 and arm 193 has a cultivation line 16
It is possible to freely move to any cultivation line 16 without interfering with the above and without interfering with each other across the panel server 18. Here, when transplanting from the first to the second or second to the third stage, the spacing machine 19 moves to the front of the return line of the previous stage, and the cultivation panel 26,27 at the line exit. All of the 98 strains 24 accommodated in each of the cultivation cups 25 are collectively lifted.

To lift the stock 24, first, the tip support arm
192 is extended so that the receiving member 192M is located right above the boundary position between the panel at the exit position and the next panel. In this state, the base 191 is lowered so that the receiving member 192M reaches the upper surface of the panel. Next, the mutual distance between the rail members 193A is adjusted according to the distance between the rows of the front stage panel, and then the stock support rail 193 is extended. This allows
The rail members 193A of each pair sequentially pass through both sides of the cultivation cup 25 of each strain 24 along the panel surface, and the tips are receiving members.
192M is engaged and supported. When the base 191 is raised in this state, the flanges 255 of the cultivation cup 25 are locked by the rail members 193A, and the plants 24 are taken out from the panel and held above.

While lifting the stock 24, each rail member 193A
The interval between columns is expanded so as to correspond to the interval between columns of the front stage panel, and thereby the interval between columns of the stock 24 is expanded. After lifting the strain 24, perform intra-row expansion. In the in-row space expansion, first, the mutual space between the engaging members 194M along each rail member 194A is adjusted to match the in-row space of the panel of the previous stage. Then, the intervals of the rail members 194A and the like are adjusted so that they are located between the stocks 24 held by the stock support rails 193. Next, the auxiliary arm 194 is extended and each engaging member 19 is extended.
4M is placed beside the cultivation cup 25 of each strain 24 and the root hanging from it. In this state, each engaging member 194M
When raised, the engaging members 194M sandwich the corresponding cultivation cup 25 of the plant 24 from below. In this state, the respective engaging members 194M are moved and adjusted so that the mutual intervals match the in-row intervals of the panel of the rear stage. As a result, the stock 24 having the cultivation cup 25 sandwiched between the engaging members 194M becomes the rail member 19
It moves along 4A, and has an interval corresponding to the in-row interval of the rear stage panel. As a result, the in-row spacing of the stock 24 is expanded.

While performing the in-row spacing expansion, the spacing machine 19 moves to the front of the feed line of the rear stage. In the front of the feed line of the rear stage, when the in-row spacing is expanded, the auxiliary arm 194 is contracted and the base 191 is lowered. As a result, the stock holding rail 193 and the tip support arm 192 are lowered, and the stock 24 that has been supported is placed on a new panel supplied from the panel server 18 at the line entrance. By the above, the transplantation of the stock 24 for one panel and the bidirectional expansion of the stock interval are performed.

In order to expand the space between the rows and within the rows, after the rail members 193A and the engagement members 194M are once wider than the desired spacing (here, the spacing corresponding to the rear stage panel). , Operate to shorten to this desired interval. As a result, the amount of movement for adjusting the spacing becomes large, and malfunctions and the like due to sliding resistance can be eliminated and reliable operation can be obtained. In addition, when placing the plant 24 on a new panel, after the plant holding rail 193 is lowered to the vicinity of the panel surface (for example, the height at which the bottom of the cultivation cup 25 reaches the panel surface), the plant holding rail 193 is once set to a predetermined height. Raise
Try to lower it to the panel surface again. As a result, even if the stock 24 does not fit properly into the hole of the panel when it first descends to the panel surface, it is moved by performing the rise and fall again and comes to have the correct posture.

(Effect of Spacing Machine) According to the spacing machine 19 of the present embodiment, the stocks 24 on the panel of the exit line of the preceding stage return line are collectively lifted and are integrated into the panel of the entrance line of the subsequent stage feed line. Can be transplanted. Therefore, as compared with the case where the strains 24 are transplanted row by row or one by one, the transplanting work can be performed more quickly and the efficiency can be improved. Further, since all the stocks 24 on the panel are handled collectively, the stocks 24 can be transferred from the front stage to the rear stage by moving the spacing machine 19 itself. It is possible to eliminate complications and complications. Further, the stock 24 can be put in and taken out from an arbitrary line by selecting the stop position, and it is possible to easily cope with the case where a plurality of parallel return lines and feed lines are used as in the present embodiment.

Further, in the spacing machine 19 of this embodiment, at the time of transplantation operation, the bidirectional expansion operation from the narrow stock interval corresponding to the panel of the front stage to the wide stock interval corresponding to the panel of the rear stage is simultaneously performed. It can be performed, and both space efficiency and work efficiency can be improved as compared with the case where each is performed by another device. And with rail member 193A, stock 24
And the stocks 24 in each row that have been lifted are moved along the rail member 193A by the engaging members 194M of the auxiliary arm 194, the inter-row spacing and intra-row spacing can be adjusted reliably and easily. At the same time, the mechanism can be simplified. Furthermore, the inter-row spacing adjustment operation can be performed simultaneously when the stock is lifted and raised, and the intra-row spacing adjustment operation can be performed simultaneously when moving between lines, thus further improving work efficiency.

On the other hand, in the spacing machine 19 of the present embodiment, since the rail member 193A for lifting the stock 24 extends along the panel surface, it does not damage the overgrown leaves. Further, since the tip end of the rail member 193A is supported by the tip holding arm 192, the rail member 193A can withstand the load of a large number of stocks 24. This tip holding arm 192 also descends from the upper side to the far side end of the panel, so that the leaves of the stock 24 are not damaged. Further, the auxiliary arm 194 extends between the roots of the lifted stock 24, and each stock 24 is engaged by raising the engaging member 194M, so that the roots are not damaged.
And each arm 192, 194 and rail 193 is a frame
Since all can be stored in 190, it does not interfere with the cultivation line 16 when moving, and it can be moved across the panel server 18 by raising the base 191, so it can move independently. It is also possible to increase the degree of freedom of each operation to simplify the control procedure and improve efficiency.

Further, when expanding the space between rows and within the rows, each rail member 193A and each engagement member 194M is once expanded to a size larger than the desired space and then operated so as to be contracted to this desired space. As a result, the movement amount for adjusting the interval can be increased, and malfunctions and the like due to sliding resistance can be eliminated and reliable operation can be obtained. Further, when mounting the stock 24 on a new panel, the stock holding rail 193 is lowered to near the panel surface, then once raised to a predetermined height, and then lowered again to the panel surface. Even if the stock 24 does not fit properly into the hole of the panel when it descends to the surface, it can be moved by moving up and down again, and can be stored in the correct posture.

The present invention is not limited to the above-mentioned embodiment, but each device in the plant factory 10 and the cultivation panels 26-28.
The shape, arrangement, number of installations, etc. of each of the above may be appropriately selected for implementation. That is, in the spacing machine 19, if the rigidity of the stock support rail 193 can be made sufficient, the tip support arm 192 may be omitted, and the mechanism for adjusting the inter-row adjustment of the tip portion can be omitted, which simplifies the structure. Can be achieved. However, according to the above-described embodiment, the base end side and the tip end side are moved together, so that the inter-row adjustment can be surely performed. Further, the engaging member 194M is not limited to the substantially U-shaped member, but a pair of engaging rods may be erected up and down to lock the stock 24, in short, the stock supported by the rail member 193A. It is sufficient if each can be moved.

Further, in the above embodiment, the stock support rail 193 is used.
Although the auxiliary rail 194 and the auxiliary rail 194 are both formed so that the inter-row spacing can be adjusted, the auxiliary rail 194 may have a fixed inter-row spacing.
In this case, after lifting the stock 24 with the stock support rails 193, adjust the stock support rails 193 according to the inter-row spacing of the auxiliary rails 194, and after adjusting the intra-row spacing by the auxiliary rails 194,
The stock support rails 193 may be operated so as to match the stock spacing of the next stage. In this way, the auxiliary rail 194
The column-to-row spacing adjustment mechanism is not required, and the structure can be simplified.

Further, as shown in FIG. 25, the tip members 195B of the auxiliary arms 194 of each row may be connected to each other, the distance between the tip ends of the auxiliary arms 194 of each row can be regulated, and the corresponding stock support can be supported. The inconvenience of being separated from the rail 193 more than necessary can be eliminated, and the operation can be performed more reliably. At this time, the tip member 195B is extended downward, and the connecting member 19 is provided at the lower end thereof.
By connecting with the 5D, it is possible to eliminate inconveniences such as contacting and damaging roots hanging from the stock 24 supported by the stock support rail 193. This connecting member 195D needs to be a pantograph-type link when the auxiliary rail 194 can be adjusted between rows, but when it is not adjusted, a simple rod or the like may be used.

Further, the connecting mechanisms 192K, 193K, 194K are not limited to the pantograph mechanism using the links, but may have other structures, for example, the moving members are sequentially connected by the coil springs having the same spring constant. Each can be expanded and contracted while maintaining the same mutual spacing. Further, the spacing machine is not limited to the one in which a plurality of rows of strains are collectively lifted and expanded while being expanded in two directions, and a pair of rail members 193A is used.
Alternatively, the implanting member 194M may be provided only in one row, and the implanting may be performed while performing only in-row expansion for each row. If the number of strains in each cultivation panel in the front and rear stages is different,
Row-wise porting is appropriate, and such a configuration is sufficient. However, it is possible to improve work efficiency and the like by making the number of strains of each panel the same as in the above-mentioned embodiment and collectively transplanting with a spacing machine.

Further, in the cultivation panels 26 to 28, the groove or the like for guiding the rail member 193A for supporting the stock is, for example, a concave groove in which the rail member 193A can be housed on both sides of the row of the holes 26A to 28 for housing the stock 24. Can be realized by forming On this occasion,
Two rail members 193A are arranged between the adjacent holes 26A to 28, but not limited to the individual grooves corresponding to the respective rail members 193A, but may be wide grooves that collectively accommodate the two. Further, the groove for guiding the rail member 193A is not limited to those engraved from the surface of the cultivation panels 26 to 28, and it may be provided on the convex portion formed on the surface so that the bottom surface thereof may coincide with the panel surface, You may provide this convex part intermittently. For example,
In the cultivation panel 27 shown in FIG. 26, the intermittent protrusions 27E are formed between the holes 27A in each row, and the continuous protrusions 27F are formed between each row.
Is provided. Here, a groove 27G is formed between the convex portion 27E and the convex portion 27F, and the stock support rail 193 can be inserted therethrough. The bottom surface of the groove 27G is the same surface 27D as the peripheral portion of the hole 27A formed between the convex portions 27E. By forming in this way, it is possible to avoid a decrease in panel strength and ensure the ease of insertion of the rail member 193A.

A pair of rail members 19 is used as a support.
Not limited to 3A, it may be one having an individual support portion similar to the engaging portion 194M of the above embodiment on one side, or the like, and the in-row spacing may be adjusted by adjusting the spacing of each individual support portion Good. Further, the present invention is not limited to the consistent plant factory as in the above embodiment, but may be applied to a cultivation line that only grows seedlings procured from outside. Furthermore, it is not limited to the panel type, and may be applied to a line that conveys a strain by a continuous conveyor, or not limited to the cultivation line and may be a take-out part to a harvesting device, etc., and an application site may be appropriately selected.
