The operation status can be grasped by the operation panels 65 and 66, and each device can be operated individually by operating each switch.

The operation of the seedling raising facility having such a configuration will be described. In the seeding device 50, the seedling raising box is sequentially seeded,
The seedling-raising boxes that have undergone the sowing process are sequentially conveyed by the feed conveyor 51 onto the belt conveyor 61 in the shelving device 60. At this time, on the chain conveyor 71 on the side of the shelving device 60, the storage cart 75 is placed in advance, and when this state is detected by the cart sensor 83d, the motor 71b for driving the chain conveyor 71 is detected. When the carriage 75 is operated, the carriage 75 is guided and moved by the guide body 72b, and when the end in the transport direction is detected by the carriage sensor 83c, the air cylinder 73f is operated to operate the stopper 73c and the chain conveyor. 71
Is stopped. As a result, the rack row on the trailing end side of the storage cart 75 in the transport direction is moved to the rack loading pusher of the rack loading device 60.
The position is opposite to 68.

On the other hand, the elevator 63 in the shelving device 60 is at the lowermost position, that is, the upper surface of the roller conveyor pair 62 placed on the upper side thereof is the lowest shelf of the storage cart 75 placed on the chain conveyor 71. And the distribution guide 62e at the starting end of the roller conveyor pair 62 has a rear opening,
The rod of the air cylinder 62g is advanced so as to be located on the roller conveyor 62r near the chain conveyor 71. In such a state, the seedling raising box that has been sown by the belt conveyor 61 is conveyed onto the roller conveyor pair 62, and is conveyed onto the roller conveyor 62r near the chain conveyor 71 by the distribution guide 62e. The seedling raising box carried on the roller conveyor 62r is carried to the end portion thereof, abuts on the stopper 62l, and stops on the end portion. At this time, when the nursery box sensor 82a detects that the nursery box is being conveyed on the roller conveyor 62r, the air cylinder 62g is operated to retract the rod, and the rear end of the sorting guide 62e is the other roller conveyor. When the guide sensor 85 is rotated so as to be positioned above the 62r and such a state is detected by the guide sensor 85, the operation of the air cylinder 62g is stopped. And
The seedling raising box to be conveyed next is positioned on the other roller conveyor 62r by the distribution guide 62e, conveyed to the end portion by the roller conveyor 62r, and abutted on the stopper 62l and positioned on the end portion. However, when the nursery box sensor 82b detects that the nursery box is being conveyed on the roller conveyor 62r, the rod of the air cylinder 62g is advanced by a predetermined amount and the air cylinder 68a of the shelving pusher 68 is advanced by the rod. The seedling raising boxes located at the terminal end of the roller conveyors 62r are integrally pushed and stored in the lowest shelf of the shelf row of the storage cart 75 on the terminal side in the transport direction. Air cylinder 68a
When the nursery box housing sensor 82 detects that the two nursery boxes have been housed in the lowermost shelf after advancing by a predetermined amount, the air cylinder 68a is operated to retract the rod, and at the same time, the lift table is lifted. 63 A hydraulic cylinder 63c for raising and lowering is operated to raise the lifting platform 63.

The height position of the lifting platform 63 is captured by the level sensor 84. When the level sensor 84 detects that the level is raised by one shelf in the storage cart 70, the operation of the hydraulic cylinder 63c is stopped, and accordingly, The upper surface of the roller conveyor 62 is opposed to the second shelf from the bottom of the storage cart 75 placed on the chain conveyor 71. In such a state, the seedling raising boxes transported as described above are sequentially transported to the end portions of the roller conveyors 62r and juxtaposed at the end portions, and the shelving pushers 68 integrally store them.
Store in 75 shelves and raise the lifting platform 63 by one shelve.

By repeating such operations, when the seedling raising boxes are stored in all the shelves of the shelf row on the end side in the transport direction of the storage cart 75, the stopper 73c for driving the air cylinder 73f arranged in the transport area of the chain conveyor 71 Is operated to release the stopped state of the storage cart 75 by the stopper 73c and drive the motor 71b to operate the chain conveyor 71. As a result, the storage cart 75 is transferred to the terminal end in the carrying direction, and when the carrying sensor 83b detects the terminal end in the carrying direction, the air cylinder 73e of the stopper 73b arranged in the carrying area of the chain conveyor 71 is operated. The operation of the chain conveyor 71 is stopped, and the central row of shelves in the storage cart 75 faces the shelving pusher 68. During this time, the driving of each roller conveyor 62r is stopped. Then, in such a state, the driving of each roller container 62r is restarted, and the seedling raising box is conveyed to the end portion of each roller conveyor 62r. In this case, since the lifting platform 63 is at the uppermost position, the storage of the seedling raising boxes in the central shelf row of the storage cart 75 is performed sequentially from the uppermost shelf to the lower side,
The operation of storing the seedling raising box in each shelf is the same as that described above, and every time the seedling raising box is stored in each shelf, the elevating table 63 is lowered by one shelf.

When the storage of the seedling raising box in the shelf in the central shelf row of the storage cart 75 is completed, the storage cart 75 is transported by the chain conveyor 71 in the same manner as described above, and the shelf row on the starting end side in the transport cart 75 in the transport direction is shelved. It is located at a position facing the pusher 68, and two seedling raising boxes are integrally stored in one shelf from the lower shelf after the push.

When the storage of the nursery boxes on all the shelves in the storage cart 75 is completed, such a state is notified, the storage cart 75 is unloaded from the chain conveyor 71, and is positioned above each pit 93 in the germination section 94. By controlling the atmosphere of the storage cart 75 at such a position, germination of each nursery box is promoted.

Thus, during such a shelving operation, for example, although the roller conveyor 62r driving motor 62a is driven, the nursery box sensors 81a and 81b on each roller conveyor 62r do not detect the transport of the nursery boxes. If each roller conveyor 62r
Although the nursery box is placed at each end, the nursery box storage sensor 82 is the air cylinder for pushing the shelving pusher.
If the operation of 68a is not detected, or if the carriage 75 is placed on the chain conveyor 71 but the carriage sensor 83a does not operate, the nursery box is moved into each shelf of the storage carriage 75. Level sensor 85 despite being listed
If the operation is not performed in spite of the fact that a predetermined operation should be performed, such as when the operation of the lifting platform 63 lifting hydraulic cylinder 63c is not detected, the sequencer 90
All the operations of the shelving unit are stopped, the warning light 65n is turned on, and the buzzer 65p is sounded. As a result, transportation of the nursery boxes, transfer, and transfer of the storage cart 75 are stopped, and it is possible to prevent the troubles from being propagated by the successive transport of the nursery boxes, and to prevent the nursery boxes from colliding with each other. There is no fall or drop of the nursery box from the roller conveyor 62r.

Further, if the transfer of the seedling raising box from the roller conveyor pair 62 to each shelf of the storage cart 75 is not reliably performed, a warning is issued particularly, the driving of the shelving pusher 68 is stopped, and the roller conveyor 62r Each drive system is sequentially stopped from the terminal end in the transport direction of the seedling raising box, such as stopping driving, stopping driving of the sorting guide 62e, and stopping driving of the belt conveyor 61. In this case, the trouble is dealt with by the manual operation.

Furthermore, in the seeding device 50 that is connected to the shelving device 60, if a missing box occurs, or if a problem occurs in the seeding device 50, if the transport of the nursery box is stopped,
An alarm is issued and all operation of the shelving device 60 is stopped. In this case, the warning by the patrol light 65n and the buzzer 65p may be a voice warning by the voice synthesizer.

In the above-described embodiment, when the transfer of the seedling raising box to all the shelves of one shelf row in the storage cart 75 is completed, all the operations may be temporarily stopped to give an alarm. Well, on the side of the roller conveyor 62r, a cleaning mud scraper, an air gun, or a water spray is provided, and when the transfer of the seedling raising box to one shelf row of the storage cart is completed, the scraper is driven. Good.

〔effect〕

According to the present invention, when a trouble occurs during a series of shelving operations, all the operations are stopped, so that the expansion of the trouble can be prevented in advance, and furthermore, the trouble can be easily resolved and the work efficiency can be improved. Will be significantly improved.
