Two seedling growing boxes are integrally stored on one shelf T.

Thus, with the seedling growing box S stored on each shelf T, the seedling growing boxes S are moved to that position or another location to promote germination of the seedlings.

Next, the operation when transferring the seedling box S to the greening storage cart 55 will be described. First, the pushing member 68c shown in FIGS. 7a and 7b is attached to the tip of the air cylinder 18a of the shelving pusher 18.
Install it in place of 8c. As shown in FIGS. 1 and 3, the seedling raising boxes S are stored on each shelf T, and when the seedlings have germinated, the germination storage cart 45 and the empty greening storage cart 55 are placed on each shelf. It is placed on chain conveyors 41 and 51.

Initially, the storage cart 45 for germination and the storage cart 51 for greening are placed on the chain conveyors 41 and 51, and in this state, the cart sensors 33d and 37
When detected at point d, the motors 41b and 51b for driving the chain conveyor are driven at high speed, and the two rows of storage carts 45 and 55 are guided by the guide bodies 42b and 52b and moved at high speed, and are moved to the end side in the conveyance direction. When the ends are detected by the truck sensors 33c' and 37c', the motors 41b and 51b both change to low speed rotation, and the air cylinders 43f and 53f are activated to operate the stoppers 43c and 53c detected by the truck sensors 33c and 37c. is operated, and the driving of chain conveyors 41 and 51 is stopped. As a result, the shelf rows on the front end side in the transport direction of the two rows of storage carts 45 and 55 are positioned opposite to the shelving pusher 18 in the shelving device 10. At this time, the storage cart 55 for greening is lifted and installed so that it is at a position one shelf above by driving the cylinder 65 of the lifting device 60 shown in FIG.

On the other hand, the elevating table 13 in the shelving device 10 is moved to a lower position by the action of the level sensor 34, that is, the upper surface of the pair of roller conveyors 12 placed on the upper side is placed on a storage cart for germination placed on the chain conveyor 41. 45, and is opposite to the lowermost shelf T of the greening storage cart 55 placed on the chain conveyor 51. position.

That is, the mask plate 70 that is placed over the level meter 44
17 slits 44b or 44a are sealed every other step, and when the second slit 44a is detected from the bottom side opposite to the slit 44c,
The hydraulic cylinder 13c is stopped. In this state, the air cylinder 18a in the shelving pusher 18 is operated to advance the rods together with the extrusion member 68c, and the two of the germination storage carts 45 are operated.
The two seedling growing boxes are pushed out and stored together from the storage cart for germination via the guide piece 85 onto the lowermost shelf T of the row of shelves of the storage cart 55 for greening. When the seedling box storage sensor 32 detects that the air cylinder 18a has advanced a predetermined amount and the two seedling boxes S have been stored on the lowermost shelf T of the storage cart 55 for greening, the air cylinder 18a It is operated to move the platform 13 in and out, and then it is operated to raise the lifting platform 13.

The height position of the lifting table 13 is detected by the level sensor 34, and the level sensor 34 detects that the level sensor 34 has been raised by two shelves in the storage cart 45 for germination through the sealed part of the level meter 44. When detected by the slits 44c and 44a, the operation of the hydraulic cylinder 13c is stopped, and the upper surface of the roller conveyor is placed on the fourth shelf from the bottom of the germination storage cart 45 placed on the chain conveyor. Step T
be faced with. When such a state is reached, the pushing member 68c at the rod end of the cylinder 18a of the shelving pusher 18 pushes out the next seedling raising box S from the shelf T of the germination storage cart 45 to the shelf T of the greening storage cart 55. and store it on the shelf T, and raise the lifting platform 13 by two shelves.

By repeating such an operation, when all the seedling boxes S are stored in every two shelves T of the row of shelves of the storage cart 55 for greening from the storage cart 45 for germination, the lifting device 60 lifts the seedlings. The storage trolley 55 for greening is lowered, and the air cylinders 43f and 53f for driving the stoppers 43c and 53c arranged in the conveyance area of the chain conveyors 41 and 51 are operated, and the storage trolley for germination is lowered by the stoppers 43c and 53c. 45 and the storage cart 55 for greening are released from the stopped state, and the chain conveyors 41 and 5 are
1, the motors 41b and 51b are driven at high speed. As a result, the storage cart 45 for germination and the storage cart 55 for greening are transferred to the terminal end side in the transport direction, and when the front end in the transport direction is detected by the cart sensors 33b' and 37b', the motors 41b, 51
b is driven at low speed, and then the bogie sensors 33b and 37
When detected at point b, chain conveyors 41 and 5
The air cylinders 43e and 53e of the stoppers 43b and 53b arranged in one conveyance area are operated, and the chain conveyors 41 and 51 are stopped, and the central shelves of the storage cart 45 for germination and the storage cart 55 for greening are operated. Row is put on shelf 18
I was forced to face him. In this state, the afforestation storage cart 55 is lifted again to the position shown in FIG. 3 by the lifting device 60. At this time, the lifting platform 13 is at the uppermost position, so the storage of the seedling boxes S from the central shelf row of the germination storage cart 45 to the central shelf row of the greening storage cart 55 is carried out on the uppermost shelf. Seedling box S to each shelf T is carried out sequentially from tier T to the bottom every two tiers.
The storage operation is the same as described above, and each time a seedling box S is stored on each shelf T of the greening storage cart 55, the lifting platform 13 is lowered every two stages.

When the storage of the seedling boxes S on the shelves T in the central shelf row of the greening storage cart 55 is completed, the greening storage cart 55 is lowered by the lifting device 60, and the Similarly, the storage trolley 45 for germination and the storage trolley 55 for greening are transported by chain conveyors 41 and 51, and the row of shelves on the rear side in the transport direction of the storage trolley 45 for germination and the storage trolley 55 for greening is placed in the shelf. After the storage cart 55 for greening is lifted again by the lifting device 60, the two seedling boxes S are integrally moved from the lower shelf T to the position facing the pusher 18, every two stages. It is stored on one shelf T.

After this storage is completed, the seedling raising boxes S left in every two tiers in the storage cart 45 for germination and the seedling raising boxes S stored in every two tiers in the storage cart 55 for greening are placed in an appropriate place. Seedlings are cultivated and cultivated.

In addition, in this embodiment, the storage carts 45, 5
5 is moved laterally to perform the transfer to each shelf row, however, instead of this, the shelving device 10 may be moved laterally to sequentially transfer to each shelf row.

〔effect〕

When using the transfer device according to the present invention as described above, the seedling boxes can be automatically transferred, reducing labor and
It is possible to reduce the space required for transfer. First, the relative movement of the storage cart or shelving device for the seedling box, that is, the extrusion device for the seedling box, is performed at high speed.
Since the next row is then moved at a low speed, the next row can be positioned quickly, the impact on the stopper can be reduced, and the positioning accuracy can be increased, and the present invention has excellent effects.

In addition, as in the above-mentioned embodiment, the motors 41b and 51
