The method described in Japanese Patent No. 4527 has a problem that this operation is not easy because the transportation of the tiered seedling boxes taken out to the relocation part is not taken into consideration. That is, when the seedling box is sown, there is 6 to 8 kg of one seedling, and when ten seedlings are stacked,
It weighs 60-80 kg and is not easy to transport. For this reason, it is difficult to lift a product stacked on a low cradle. In this regard, if the transfer table is stacked upward at the end of the transfer table, there is no need to lift it, but since it is stacked in the frame, removal is difficult. Also, since the tiered seedling boxes are heavy, it is difficult to transfer them to the table of the transport lift device. Similarly, the loading and unloading of the transport system onto the cart is not easy. Also, the seedling box is sown on the upper surface, thinly covered with soil, and has a rib on the bottom surface of the seedling box. Since the seedling boxes are piled up, the seedling boxes that have been stacked cannot be shifted sideways, and in this regard, a general physical distribution system cannot be used. Also, the place to transport the nursery box is
Since the floor is a ground for placing soil, the floor surface is not horizontal, and a general physical distribution system cannot be used in this regard. The present invention has been made to overcome the above-mentioned problems, and to make the work from sowing to laying in a loading place continuous.

That is, the seedling transfer table 2 is adjusted to the work height of the worker, and is stacked on the receiving stand 12 of the seedling raising box stacking device 8 which is lower than the seeding transfer table 2 and is taken out from the transfer unit 13. Since the height of the start end of the box raising device 16 is the same as the height of the transfer portion 13, the box raising device 16 can be easily moved by pressing the box A.

Further, in the step-stacking seedling box raising device 16, a pair of right and left arms 19 are arranged side by side on a frame 18 placed on the floor, and a table 22 is provided at the end of the arm 19. When the user moves on the stacking seedling box A and energizes the motor 20 by the foot switch 23, each arm 19 rotates and the table 22 is stopped at the same or slightly higher position as the terminal mounting table 17, Table 22
The upper tiered seedling raising box A is placed on the terminal mounting table 17.
In this case, since the left and right arms 19 are positioned inside the frame 18 and the table 22 is positioned inside the arm 19, the table 22 can be lowered until the table 22 overlaps the frame 18 in a side view. Transfer from the factory. Further, since the arm 19 raises the table 22 as a parallel link, the motor 20 and the transmission mechanism are provided on the raising side, so that the arm 19 does not interfere with the lowering of the table 22 and has a reasonable arrangement. In addition, since the operation of the motor 20 is performed by the foot switch 23, the operator can easily perform the operation of turning the vertically stacked seedling raising seedling box A horizontally using both hands. Therefore, the vertically stacked seedling raising seedling box A is turned sideways, so that work efficiency is improved and workability is improved. Further, since the table 22 has the transport rollers 22a arranged side by side, it is not only easy to change the direction of the stepped seedling raising box A, but also to transport the transport rollers 22a to the table 2.
2, and the cost can be reduced by reducing the number of parts.

Then, a plurality of step-stacking seedling boxes A are placed on the terminal mounting table 17 by the step-stacking seedling box raising device 16, and the step stacking seedling boxes A on the terminal mounting table 17 are placed on the terminal mounting table 17. Is slid on the table 28 of the lift device 25 provided in the vicinity of, and is transferred to the transport carriage 32. The transport cart 32 runs on the traveling rail 31 by the power source 35 and stops automatically at a predetermined position. In the embodiment, the derivative 38 provided at each predetermined position is automatically controlled on the basis of a signal detected by the travel sensor 37, travels automatically on the travel rail 31, and automatically stops at the predetermined position. Next, the engaging hooks 62 provided on the supply carriage 49 are engaged with the engagement shafts 63 provided on the transport carriage 32, and in this state, the step stacking seedling box A on the transport carriage 32 is provided. Is mounted on the supply cart 49, and the transport cart 32 is returned to the original place.

In this case, the supply cart 49 is a tiered seedling raising box A
Since there is a pair of left and right guide rails 50 having a width and a front-to-rear length on which to place the container, the step-raising seedling box A on the transport carriage 32 is moved onto the guide rails 50. Supply trolley 49
Is provided with guide rods 53 on both sides of the guide rail 50. Since the guide rail 50 is inclined high at the start end and low at the end end, the stacking seedling raising box A can be easily moved to the end side, and The seedling raising box A comes into contact with the stopper plate 57 at the tip of the fork portion 56 and stops, and then the step stacking seedling raising boxes A on the transporting transport cart 32 are sequentially replaced with the supply carts 49. Is provided with a power source 35, a battery 40, and the like on a traveling frame 33 having a predetermined left-right width.
Much higher. On the other hand, in order to increase the number of stacked units in the transfer unit 13 and to reduce the impact of descent when laying the nursery box A in the nursery box parallel device 46, it is preferable to set the height as low as possible. When using the transport trolley 32, the height of the transport trolley 32 will not match both when loading and unloading, but the transport trolley 3
In order to load the seedlings on the tray 2, the tray-raising seedling box raising device 16 easily raises the tray-raising seedling boxes A while transporting them. At the same time, lower the height. Therefore, since the transfer unit 13, the stacking seedling box raising device 16, the terminal mount 17, the transport trolley 32, and the supply trolley 49 can be configured, the cost is reduced.

The traveling frame 33 of the transport carriage 32
Since the horizontal axis rollers 41 are juxtaposed on the upper surface of the transfer member 13, it is easy to push the horizontal axis rollers 41 from the rollers 14 of the transfer unit 13. Therefore, the box-raising seedling box A can be taken out and transported without the need for manual lifting. In addition, the transport trolley 3
Since the second operation panel 39 is arranged at a predetermined interval laterally from the traveling frame 33, it is also possible to change the direction of the stacked seedling raising box A, and it does not affect the unloading of the seedling box A at all. In addition, operability and workability are improved. Since the stacked seedling raising box A taken out of the relocation unit 13 is temporarily stored on the terminal mounting table 17 instead of being directly mounted on the transport cart 32, the capacity of the seedling box paralleling device 46 and the transfer for sowing are set. Even if there is a difference in the capacity of the table 2, work can be performed continuously. In addition, since the height of the terminal mounting table 17 and the height of the transport vehicle 32 are matched with each other, the lifting device 25 is provided between the terminal mounting table 17 and the transport vehicle 32, so that it can be performed very easily. . In addition, since one set of tiered seedling raising boxes A is moved up and down by the lift device 25 without moving the entire mounting table 17 for the terminal, the lift device 25 can be manufactured at low cost (in the embodiment, a cylinder is used). However, it can also be performed by a cam mechanism, and the cost is further reduced).

Thus, the supply cart 49 travels on the traveling rail 31 extending to the placement nursery 44 in the greenhouse 43 as it is, and the table 53 of the supply cart 49 is
When the fork portion 56 of the seedling box feeding device 48 described below is positioned between the left and right seedling box support members 119 of the seedling box feeding device 48, the contact portion 58 protruding downward at a predetermined position comes into contact with the seedling box feeding device 48 and stops. In this state, the stacked seedling raising box A on the fork portion 56 is located in the stacked storage space of the seedling raising box supply device 48. In this case, since the fork portion 56 of the guide rail 50 of the supply cart 49 is formed in an overhang shape with respect to the front horizontal rod 51, the frame 77 of the seedling box supply device 48 does not interfere. Supply becomes easy. Further, since the fork portion 56 is formed narrower than the left and right width of the seedling raising box A, it can be easily inserted between the left and right seedling raising box supports 119. In addition, since the supply cart 49 has the traveling wheel 52 mounted on the traveling rail 31 of the placement nursery 44, if the nursery box supply device 48 is positioned with respect to the seedling box paralleling device 46 described later, Just by moving the supply cart 49 forward,

The seedling box support 119 is engaged with the lower seedling box A at the bottom of the stacked seedling box A, and the seedling box support 119 is further inserted. When it is raised, the table 53 can be pulled out rearward, and the supply of the tiered seedling box A becomes extremely easy. In this case, since the seedling raising box support 119 waits at a position above the frame body 77, the fork portion 56 is pulled out without interfering with the frame body 77. Also, when transferring from the fork part 56,
Although the front-rear weight balance changes, a pair of left and right support frame support frames 59 are provided at the front and rear intermediate portions of the guide rail 50, and the nursery box A filled with soil is inserted into the support frame 59, so that the simplest is the simplest.
