<p>PURPOSE:To efficiently load seedling raising boxes on a shelf, by automatically controlling a conveyor speed to transport seedling raising boxes from a seeding device to a seedling raising box retainer and change of the action position and release position of a stopper set at the end of the conveyor. CONSTITUTION:Seedling raising boxes (a) are transferred by a conveyor 2, charged with soil and seeds, then transferred to a seedling raising box retainer B, supported vertically in parallel and loaded on a seedling raising box shelf 10 by a seedling raising box heaping device C. In the operation, a stopper 17 to receive the seedling raising boxes (a) while slipping the seedling raising boxes 10a on the conveyor 7 is set at the end of the conveyor in such a way that the action position is freely changed into release position. The transfer speed of the conveyor 7 is higher than that of the conveyor 2 by a control mechanism and the stopper 17 is in release position when the seedling raising box heaping device C is not driven. When the seedling raising box heaping device C is driven, the transfer speed of the conveyor 7 is low and the stopper 17 is in action position. Consequently, operation can be carried out even during loading of the seedling raising boxes on the seedling raising box shelf 10 without interrupting transfer of the seedling raising boxes from a seeding device A.</p> |
