Effects of the Invention The known method has problems in that it is configured so that it is fed by a fast-feeding roll, and that the fast-feeding roll and the support beam are rotated by separate motors. When feeding by rapid-feeding rolls, the friction coefficient is insufficient and the material cannot be fed completely. In addition, since the rapid-feed roll and the support bar are configured to be rotated by separate motors, multiple motors are required.
The cost will be high. However, the present invention provides a stacking device which has a receiving bar 34 at the end of the transfer table 1 of the seedling box seeding device, which can receive the seedling boxes 5 transferred by the transfer table 1 and stack them by lowering them. 22, and a fast-feeding belt stand 32 on which a fast-feeding belt 33 is wound is provided between the transfer table 1 and the receiving bar 34, and both the fast-feeding belt 33 and the receiving bar 34 are rotated by one motor 30. A one-turn clutch 31 is provided between the receiving bar 34 and the motor 30, and the one-turn clutch 31 is actuated when the seedling box 5 is transferred to a position near the receiving bar 34. Since this device is a seedling box stacking device of a seedling box seeding device which is provided with a link mechanism 48, the fast-forwarding belt 33 and the support bar 34 are rotated by one motor 30, resulting in cost reduction. Furthermore, since the paper is fed by the fast-feeding belt 33 instead of the fast-feeding roll, there is little slippage.
