The supporting claw portion 26 projects into the step stacking extraction space 8 and abuts against the bottom surface of the seedling raising box A to support it. Since the cam disk 19 continues to rotate, when the maximum diameter portion of the cam disk 19 passes below the roller 20, the roller 20 starts descending and the vertical movement frame 12 returns to its original position. And then
The stop switch 48 is disengaged from the protrusion 36 of the disc 35 and turned off to stop the raising motor 22 and the vertical movement frame 12 is put in a standby state, and the next seedling raising box transferred from the seedling raising box transfer table 1. Accept A and raise again. Repeating this, the nursery box A transferred from the nursery box transfer table 1
Are sequentially stacked in the stacking extraction space 8.

When the vertical movement frame 12 raises and fills the last seedling raising box A into the stacking take-out space 8, the detection switch 49 is turned on because the upper surface of the stepped seedling raising box A contacts the detection switch 49. Then, by energizing and operating the transfer motor 45 to rotate the drive gear 42 to move the endless chain 44, the rear surface of the lowermost stage of the seedling raising box A in which the transfer protrusions 43 provided on the endless chain 44 are stacked. The seedling raising box A stacked on the stacking and taking-out space 8 slides on the supporting claw portions 26 of the supporting member 25 and is transferred by the endless chain 44 to the transferring and taking-out table 46. Is taken out from the stepped stacking and taking-out space 8 and conveyed to a predetermined position for post-treatment such as seedling raising and packing.

When the stacking and raising box A is taken out from the stacking and taking-out space 8, the vertical moving frame 12 descends and receives the next raising box A transferred from the raising box transfer table 1. , The above operation is repeated. In this case, the right frame 7
Since the guide guide 33 is provided in the container, the shoulder of the raising seedling raising box A abuts and is pushed to the transfer device 40 side, and abuts the guide guide 34 provided on the left frame 6, so that the stacked seedling raising box A is It is located where the transfer protrusion 43 always comes into contact.

Since the transfer device 40 is configured to slide and transfer the seedling raising box A stacked on the support claw portion 26 of the support member 25, a separate support member or the like is not required. Since the length direction of the support claw portion 26 of the support member 25 and the transfer direction of the transfer protrusion 43 may be parallel to each other, not only the same direction as the transfer direction of the seedling raising box A transferred by the transfer table 1, It is also possible to adopt a configuration in which they are transferred in the intersecting direction.

[0016]
