Description

Detailed Description of the Invention "Industrial Application Field" The present invention is an automated system for raising seedling boxes in which sown seedling boxes are stored in multiple tiers on storage shelves of a seedling cart, and seedlings are raised for a certain period of time in a greening room. Regarding a shelving device.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Publication No. 56-2678, there is a technique for automatically placing a seedling-growing box in which seeds have been sown on a cart.

"Problems to be Solved by the Invention" In the above-mentioned conventional technology, the work of moving the empty cart to the position where the nursery box is loaded and the work of moving the trolley from the position where the nursery box is loaded are manually performed. It is necessary to form a two-pronged conveyor, and to alternately deliver seedling boxes to the two-pronged feeding end of the conveyor and place them on a trolley. There were problems such as the fact that it was not easy to save labor in loading the seedling boxes onto the trolley.

``Means for Solving the Problems'' However, the present invention provides a cart having storage shelves for storing seedling boxes in multiple stages, a seedling box shelving machine that sequentially feeds seedling boxes to the upper and lower stages of the storage shelf, An automatic seedling box shelving device comprising a seedling box transport conveyor whose elevation angle is varied in conjunction with the shelving machine,
A means for moving the carts is arranged in parallel on one side of the shelving machine, and is moved from a standby position before shelving the seedling boxes to a position where the seedling boxes are shelved, and from a position where the seedling boxes are shelved to a standby position after shelving the seedling boxes. The present invention is characterized in that the cart is configured to be automatically moved.

``Operation'' Therefore, the work of sequentially moving empty carts to the seedling box shelving position of the shelving machine can be performed automatically, and the successively delivered seedling growing boxes can be efficiently placed on a plurality of carts. , it is possible to easily save labor in loading seedling boxes onto carts, and it is also possible to easily shorten the time required to replace empty carts with empty carts. This eliminates the need for complex configurations such as bifurcating the end of the box transport conveyor and installing two shelving machines, making it easy to simplify the structure for placing seedling boxes on carts, and also installing two shelving machines. Multi-layered seedling boxes can be placed on the cart in multiple rows with simple control to adjust the position of the cart, making it easy to improve the throughput of sown seedling boxes and the automatic control function. It is possible.

Now, when the lifter 24 of the shelving machine 20 is at the lowest position, as shown in FIG. When the cylinder 27 makes one movement on one shelf 18, the first seedling box 15 is sent in, and when the cylinder 27 makes one movement, the second seedling box 15 is sent to the shelf 18. At the same time, the second seedling growing box 15 pushes the first seedling growing box 15 to the back of the shelf, and when the first box 15 is stored in a predetermined position, the contact pressure of the surface pressure plate 28 increases. Based on this, the sensor 29 operates and drives the motor 23 to raise the lifter 24 by one shelf. In other words, when the switch 48 detects the next upper shelf 18 with the lifter 24 rising and the sensor 29 not detecting a box, the lifter 24 stops moving upward, and the seedling box 15 is stored again, and this process is repeated for the last time. Go to the top shelf 18.

When the storage of the boxes 15 on the top shelf 18 is completed and it is confirmed that all the shelves in the front chamber 19a are stored, the cart 17 is moved to the switch 40 by the chain conveyor 22b.
Thereafter, as shown in FIG. 2B, the seedling-growing boxes 15 are placed from the uppermost shelf 18 to the lowermost shelf 18 of the central chamber 19b in the same manner as described above.

When all the shelving in the central chamber 19b is completed, the cart 17 is moved to the switch 41 position, and then the cart 17 is moved from the lowest shelf 18 to the uppermost shelf 18 of the rear chamber 19c to be shelved again. When all the shelving in the rear chamber 19c is completed, the chain conveyor 22b transports it to the end of the movement and sends it to the greening room 5.
When the passage of the cart 17 is detected, each conveyor 22a is driven and the next cart 17 is sent to the putaway machine 20 position. In addition, in this case, the shelving work order continues and in the front chamber 19a, as shown in FIG.
As shown in the figure, the central chamber 1 is located below the top shelf 18.
9b, the lowest shelf 18 as shown in FIG.
In the upper part of the rear chamber 19c,
As shown in the figure, the shelving work is performed successively from the top shelf 18 downward.
