The harvesting device 30 is a device that harvests plants that have grown to a size that can be harvested in the cultivation unit 22 placed on the shelves 21 of the shelf structures 15 to 20 from the fixed planting panel 25.

  As shown in FIG. 2, a rail 31 made of steel or the like is installed on the upper part in the cultivation room 13 so as to extend in the horizontal direction along the ceiling 32. The rail 31 is installed in the air near the ceiling 32 via a beam member 33 or the like that connects the upper ends of the shelf structures 15 to 20 adjacent in the direction along the X axis. As shown in FIG. 1, the rail 31 extends along the Y axis between the odd-numbered shelf structures 15, 17, 19 and the even-numbered shelf structures 16, 18, 20 in a plan view from above. When the position on the extending passage is the first position P1, and the position where the planting device 29 and the harvesting device 30 are respectively installed is the second position P2, the circulation path passing through the first position P1 and the second position P2 Forming.

As shown in FIG. 1, the straight rail portion 34 has a first position P <b> 1 between the odd-numbered shelf structures 15, 17, 19 and the even-numbered shelf structures 16, 18, 20 and the planting device 29 and the harvesting. A rail portion extending in the Y-axis direction through each of the second positions P2 where the device 30 is installed, and a rail portion extending in the X-axis direction outside the region where the shelf structures 15 to 20 are installed. In the plurality of linear rail portions 34, the rail portion extending in the X-axis direction and the rail portion extending in the Y-axis direction are connected by the curved rail portion 35, so that the rail 31 has the first position P1 and the second position P2. A circulation path is formed via

  As shown in FIG. 4, a moving body 36 is supported on the rail 31 so as to be movable in the air along the rail 31. That is, the moving body 36 has a plurality of pairs (two pairs as an example in the present embodiment) of driving rollers 38 inside the casing 37. Each of the driving rollers 38 is partially exposed through a notch 39 formed on a surface of the casing 37 that faces the side surface of the rail 31, and is exposed from the notch 39 of the pair of driving rollers 38. The rails 31 are sandwiched between the exposed portions. Then, the driving roller 38 rotates based on a driving force from a driving source (not shown) such as a motor, so that the moving body 36 moves in the air along the rail 31.

  Below the moving body 36, the transfer mechanism 40 configured to be able to transfer the cultivation unit 22 to and from the predetermined shelf 21 at the first position P <b> 1 in the cultivation room 13 moves in the air together with the moving body 36. It is arranged to be possible. A frame structure 43 including a pair of vertical plates 41 along a vertical plane and a plurality of horizontal shafts 42 connecting the vertical plates 41 in a parallel manner is suspended from the moving body 36. It is suspended via a lowering member 44. Incidentally, the vertical plate 41 has a rectangular shape whose longitudinal direction is the horizontal direction, and the length dimension in the longitudinal direction is substantially the same as the length dimension in the longitudinal direction of the cultivation unit 22.

  The suspension member 44 is configured such that the length in the vertical direction expands and contracts as shown in FIG. 2 in accordance with the driving of a lifting device (not shown) disposed in the casing 37 of the moving body 36. . Therefore, the delivery mechanism unit 40 suspended from the movable body 36 via the suspension member 44 moves in the horizontal direction as the movable body 36 moves along the rails 31, while the suspension member 44 extends and contracts. It moves in the vertical direction as it moves. As a result, the delivery mechanism 40 is opposed to the opening 23 of the desired shelf 21 among the plurality of shelves 21 provided on the plurality of shelves 15 to 20 so as to extend in a plurality of rows and stages. It can be moved to a position.

  As shown in FIG. 4, in the vicinity of both ends of the frame structure 43 in the horizontal direction of the vertical plate 41, the sprocket 45 is rotatable in the forward and reverse directions around a shaft portion 46 parallel to the horizontal shaft 42, respectively. It is supported by. Between the paired sprockets 45, an endless chain 47 that circulates when the sprocket 45 rotates based on a driving force from a driving source (not shown) is hung. Further, in a part of the chain 47 in the circumferential direction (two places as an example in the present embodiment), a shaft shape that can be engaged with the hook-shaped engaged portion 28 in the cultivation unit 22 during the circular movement of the chain 47. The engaging portion 48 is provided.

  In the present embodiment, the delivery mechanism unit 40 includes a frame structure 43 suspended from the moving body 36, a pair of sprockets 45 rotatably supported by the frame structure 43, and a pair of sprockets 45. The chain 47 includes an endless chain 47 that is hung in between, and an engaging portion 48 that is provided in a part of the chain 47 in the circumferential direction. And the cultivation unit 22 spans the 1st position P1 which can deliver the cultivation unit 22 between the one shelf parts 21 in the shelf structures 15-20, and the 2nd position P2 different from the said 1st position P1. The transfer mechanism 49 that can transfer the above-mentioned structure includes the rail 31, the moving body 36, and the delivery mechanism unit 40.

  Next, the operation of the cultivation apparatus 11 configured as described above will be described below by focusing on the operation when the cultivation unit 22 is transferred by the transfer mechanism 49. In the following, among the upper, middle, and lower three-tier shelf portions 21 schematically shown in FIG. 5, cultivation is performed with the middle shelf portion 21 in the right-side even-row shelf structure 16 (18, 20). A case where the unit 22 is delivered will be described as an example.

  As shown in FIG. 5, when the cultivation unit 22 is transferred by the transfer mechanism 49, when the cultivation unit 22 is delivered between the shelf portions 21 of the shelf structures 15 to 20, the cultivation unit 22 is delivered. The delivery mechanism 40 is positioned at a position facing the shelf 21 in the X-axis direction. That is, in the transfer mechanism 49, the moving body 36 is moved in the air along the rails 31, and the delivery mechanism unit 40 is moved up and down by extending and retracting the suspension member 44, thereby moving the delivery mechanism unit 40 to the predetermined shelf 21. To the first position P1 where the cultivation unit 22 can be delivered.

  At this time, the delivery mechanism unit 40 moves in the air together with the moving body 36 from a position different from the first position P1 (for example, the second position P2) to the first position P1. Therefore, as shown by a two-dot chain line in FIG. 2, between the odd-numbered shelf structures 15, 17, and 19 and the even-numbered shelf structures 16, 18, and 20 where the first position P <b> 1 is set in this case. Even if an article 50 such as a cardboard box is stacked or a groove 51 for drainage or the like is dug on the passage, there is no problem in movement of the delivery mechanism 40.

  Then, as shown in FIG. 6, when the sprocket 45 in the delivery mechanism 40 rotates in the counterclockwise direction indicated by the arrow in FIG. 6, the chain 47 rotates. For this reason, the engaging portion 48 provided in a part of the chain 47 in the circumferential direction similarly moves in the counterclockwise direction on the outer side of the circulation locus of the chain 47. Then, the engaging portion 48 that has rotated in the counterclockwise direction together with the chain 47 is engaged with the engaged portion 28 in the cultivation unit 22 to be transferred. When the sprocket 45 continues to rotate further counterclockwise from that state, the cultivation unit 22 is horizontally moved in the direction in which the cultivation unit 22 is pulled out from the shelf 21 while the engagement portion 48 is engaged with the engaged portion 28. .

  Then, as shown in FIG. 7, the cultivation unit 22 that has been placed on the predetermined shelf 21 in the even-numbered shelf structure 16 (18, 20) on the right side is covered at both ends in the longitudinal direction. With the pair of engaging portions 48 in the chain 47 engaged from below with the engaging portion 28, the transfer mechanism portion 40 of the transfer mechanism 49 is transferred. Then, when the moving body 36 moves along the rail 31 from that state, the delivery mechanism unit 40 is transferred to the second position P2, which is a position different from the first position P1, or in an empty shelf state, for example. It is transferred to another first position P <b> 1 that faces a certain other shelf 21. At the second position P2, the plant seedling N is planted by the planting device 29, or the plant grown by the harvesting device 30 is harvested, while at the other first position, other shelves in an empty shelf state. The cultivation unit 22 is delivered from the delivery mechanism unit 40 to the unit 21.

  Contrary to the above case, for example, the cultivation unit 22 in which the plant seedlings N are planted by the planting device 29 at the second position P2 is delivered to the shelf 21 in an empty shelf state at the first position P1. In the case, it is as follows. That is, as shown in FIG. 7, the transfer mechanism 40 that is in the state of supporting the cultivation unit 22 is moved to the position facing the shelf 21 in the empty shelf state and the moving member 36 is moved up and down the lifting member 44. Move through the air through.

  Then, from the state shown in FIG. 7, the sprocket 45 in the delivery mechanism unit 40 is now rotated clockwise in FIG. 7. Then, in the cultivation unit 22 that is in a state supported by the delivery mechanism unit 40, the engaging unit 48 rotates in the clockwise direction as the chain 47 rotates in the clockwise direction. The portion of the engaged portion 28 is pushed to move horizontally in the direction to be inserted into the shelf portion 21 of the empty shelf. Then, when the chain 47 is rotated clockwise by about a half turn from the state shown in FIG. 7 to the state shown in FIG. 5, as shown in FIG. 5, the cultivation unit 22 is a delivery mechanism part of the transfer mechanism 49. 40 is delivered to a predetermined shelf 21.

  1 and 2, the left-side odd-numbered shelf structure 15 (17, 19) and the right-side even-numbered shelf structure 16 (18, 20) are designated as the first position P1 on the rail 31. It is also referred to as a first shelf structure and a second shelf structure that face each other across the straight rail portion 34 that passes. In this case, the delivery mechanism section 40 of the transfer mechanism 49 is driven in the first mode, so that the shelf section of the odd-numbered shelf structure bodies 15 (17, 19) on the left side called the first shelf structure body. The cultivation unit 22 can be delivered to and from 21. On the other hand, by driving in the second mode in which the driving direction is opposite to that in the first mode, the shelves of the right-side even-numbered column rack structure 16 (18, 20) referred to as the second shelf structure. The cultivation unit 22 can be delivered to and from 21.

  That is, in the state shown in FIG. 5, when the delivery mechanism 40 rotates the sprocket 45 in the clockwise direction as an example of the forward direction as the driving of the first mode, the chain 47 and the engaging portion 48 are also rotated in the clockwise direction. Move around. And the engaging part 48 is below the engaged part 28 of the cultivation unit 22 placed on the middle shelf part 21 of the left first shelf structure 15 (17, 19) in the middle of its circular movement. When the sprocket 45 continues to rotate further clockwise from that state, the cultivation unit 22 is pulled out from the shelf 21 while the engagement portion 48 is engaged with the engaged portion 28. Then, the cultivation unit 22 pulled out from the shelf 21 is transferred to the delivery mechanism unit 40.

  On the other hand, in the state shown in FIG. 5, when the delivery mechanism unit 40 rotates the sprocket 45 in the counterclockwise direction as an example of the reverse direction as the driving of the second mode, the chain 47 and the engaging unit 48 are also the same. Move around counterclockwise. And the engaging part 48 is below the engaged part 28 of the cultivation unit 22 placed on the middle shelf part 21 of the second shelf structure 16 (18, 20) on the right side while moving around. When the sprocket 45 continues to rotate further counterclockwise from that state, the cultivation unit 22 is pulled out from the shelf 21 while the engagement portion 48 is engaged with the engaged portion 28. Then, the cultivation unit 22 pulled out from the shelf 21 is transferred to the delivery mechanism unit 40.

  In this way, the transfer mechanism 49 that transfers the cultivation unit 22 to and from the shelf 21 in the transfer mechanism 49 switches between driving in the first mode and driving in the second mode in which the driving directions of each other are reversed. It is possible to easily transfer the cultivation unit 22 between any of the shelf portions 21 of the first shelf structure and the second shelf structure that face each other across the first position P1. Further, since the engaging portion 48 has a simple structure in which the rotation direction of the sprocket 45 that is hung on the chain 47 provided in a part in the circumferential direction is switched, it contributes to simplification of the delivery mechanism portion 40. .

According to said embodiment, the following effects can be acquired.
(1) The first position P1 corresponding to one shelf 21 of the shelf structures 15 to 20 is different from the first position P1 by the transfer mechanism 49 in the cultivation unit 22 where the plant seedlings N are planted. It can be transferred to and from the second position P2. Moreover, in the transfer mechanism 49, since the delivery mechanism part 40 which delivers the cultivation unit 22 moves in the air together with the moving body 36 that moves along the rail 31 installed in the air, the shelf structures 15 to 20 are installed. It is not necessary to secure a space for laying the rails 31 on the floor surface 14. Therefore, the cultivation unit 22 can be easily transferred while effectively utilizing the installation space of the cultivation apparatus 11.

  (2) Even if there are a plurality of straight rail portions 34 whose extending directions intersect each other between the first position P1 and the second position P2, the plurality of straight rail portions 34 are connected by the curved rail portion 35. Therefore, it is not necessary to interpose another transfer mechanism such as a conveyor for changing the transfer direction. Therefore, the cultivation unit 22 can be transferred between the first position P1 and the second position P2 by a single type of transfer mechanism 49.

  (3) The cultivation unit 22 received from the shelf portion 21 of the shelf structures 15 to 20 at the first position P1 is transferred to the first position P1 again after performing, for example, a planting process or a harvesting process at the second position P2. And it can be handed over to the original shelf part 21 in the shelf structures 15-20. Therefore, when the transfer mechanism 49 is configured to travel a plurality of moving bodies 36 along the rail 31 of the circulation path, the first position P1 while sequentially interposing a predetermined process for the plurality of cultivation units 22 one by one. And the second position P2 can be transferred to continue cultivation.

  (4) The configuration of the delivery mechanism unit 40 in the transfer mechanism 49 can be simplified, and weight reduction applied to the moving body 36 can be reduced by weight reduction through simplification of such a mechanism.

  (5) The delivery mechanism unit 40 switches the rotation direction of the sprocket 45 on which the chain 47 is hung in the frame structure 43 suspended from the moving body 36, thereby opposing the first shelf structure with the rail 31 interposed therebetween. And the delivery of the cultivation unit 22 between any one of the shelf parts 21 facing each other in the second shelf structure can be easily switched.

In addition, you may change the said embodiment as follows. Further, the following modifications may be combined as appropriate.
