Description of the Related Art There is a seedling raising method for seedlings for rice transplanters in which seedling-raised seedling boxes are stacked in many stages (for example, 30 stages) and germinated. There is provided a seedling box stacking device for automatically stacking seeding-treated seedling boxes continuously carried out from the device to a desired number of stages. Conventionally, as a seedling box stacking device of this kind, as shown in FIGS. 25 and 26, for example, a seeded seedling box 1 that has been placed in the loading mechanism A and continuously transported in tandem is transported. In two sets of lift mechanisms Ba and Bb arranged in parallel at two locations in the direction, the chains 6 are intermittently turned upward and received and supported by locking pawls 3 provided at predetermined vertical intervals and sequentially lifted. When a predetermined number (for example, five) of the seedling raising boxes 1 are vertically supported by the lift mechanisms Ba and Bb, the lowermost seedling raising box 1 supported by the lift mechanisms Ba and Bb is provided.
Are lifted and moved by the support portions 7 of the stacking devices Ca, Cb, and the other seedling raising boxes 1 are directly stacked on the lowermost seedling raising box 1 and lifted, and a plurality (five) of the seedling raising boxes 1 are stacked. The seedling box block 1a is formed, and the seedling box block 1a is laterally transported to the stacking mechanism E by the horizontal transport mechanism D, and then supplied onto the elevating platform 26 of the stacking mechanism E. While descending by the height of the seedling box block 1a, the seedling box blocks 1a are sequentially stacked on the previous seedling box block 1a, and a plurality (for example, six blocks) of seedling box blocks 1a are stacked.
Finally, the seedling raising box 1 is placed in a predetermined stage (30 stages).

た。The conventional seedling box stacking apparatus has the following problems that hinder the improvement of the processing efficiency. In the above-described conventional apparatus, two sets of lift mechanisms Ba and Bb arranged in parallel in the transport direction are configured to be driven synchronously, so that the seedling boxes that have been transported in tandem are positioned at the lower portions of both lift mechanisms Ba and Bb. It is necessary to activate both lift mechanisms Ba and Bb after reaching the respective positions. For this purpose, the front end of the nursery box, which has been conveyed in a row, is brought into contact with a stopper to position the seedling raising box at a predetermined position for lifting, and the conveyance direction After confirming that the front and rear seedling raising boxes 1 are positioned in contact with the respective stoppers, two sets of lift mechanisms Ba and Bb are simultaneously activated to perform one pitch lift. At this time, if the transport speed of the seedling raising box 1 is high, the soil in the seedling raising box will be slightly deviated forward in the traveling direction due to the impact when the stopper comes into contact with the stopper. The conveying speed of the seedling raising box 1 must be set to a relatively low speed so as to fall within a non-uniform range, which is one of the factors that hinder improvement in the processing efficiency.

, And is conveyed laterally to the stacking mechanism E. However, the interval between the lift mechanisms Ba and Bb and the stacking mechanism E cannot be made too close due to the arrangement of various mechanisms. The lateral transport distance becomes relatively large, and as a result, it takes a long time to transport the upper side of the lift mechanisms Ba and Bb to the stacking mechanism E. Of course, in this case as well, the transport time can be shortened by increasing the lateral transport speed, but in the transport of the seedling raising box 1, the transport speed is increased unnecessarily in order to suppress the shifting movement of the soil in the box. This has been one of the factors that hinder the improvement of the stacking efficiency.

った。In the conventional apparatus, when a predetermined number (for example, 5) of the seedling raising boxes 1 are vertically supported by the lift mechanisms Ba and Bb, the lowermost seedling raising boxes 1 are stacked by the stacking mechanisms Ca and Cb. The seedling raising box 1a is formed by stacking a plurality of (five) seedling raising boxes 1 by sequentially lifting and raising the other seedling raising boxes 1 by sequentially lifting the seedling raising boxes 1 on the lowermost end of the seedling raising box 1 by lifting and moving. At this time, the upper edge of the seedling raising box 1 in the lower stage is brought into contact with the locking claw 3 receiving the seedling raising box 1 thereon, and the locking claw 3 is retracted upward and outward. By swinging, the next seedling raising box 1 is directly dropped and stacked on the lower seedling raising box 1, and thereafter, the upper seedling raising boxes 1 are sequentially stacked in the same manner. In this case, when the locking claw 3 is reciprocated upward and outward to drop the next seedling raising box 1 directly on the lower seedling raising box 1 and stack it, the next seedling raising box 1 is locked by the locking claw. 3 is lifted once upward by the upward and outward swing, then unlocked and dropped onto the seedling raising box at the lower stage. In order to increase the stacking speed, the support portions 7 in the stacking mechanisms Ca and Cb are increased. As the lifting speed of the seedlings is increased, the raising and unlocking of the seedling raising box 1 by the locking claws 3 is rapidly performed, and a large lifting impact and a drop impact are generated, and the soil in the raising seedling box is displaced. There is a problem that the collapse becomes large, and there is a limit in increasing the rising speed of the support portion 7. That is, the generation of an impact due to the release of the locking from the locking claw 3 is one of the factors that hinder the improvement of the processing efficiency of the entire seedling box stacking device.

るものである。(Operation) According to the above configuration, the timing at which the seedling boxes conveyed in tandem by the carry-in mechanism reach the predetermined positions in the respective lift mechanisms depends on the conveyance interval of the seedling boxes. In each of the possible lift mechanisms, a predetermined number of seedling boxes are lifted by moving the locking claws upward in accordance with the arrival timing of the seedling boxes. At this time, the timing of activating each lift mechanism is to raise the locking claw in advance before the seedling box reaches the position for lifting, and the seedling box that has begun to be locked by the locking claw is , Further advance on the locking claw due to the inertia of the transport. In other words, the nursery box slides on the locking claws, is decelerated by frictional resistance due to the sliding, and stops with less impact. The operation of lifting the seedling box while applying sliding resistance to the seedling box in this way must be synchronized with the transport timing of the seedling box. Therefore, it is impossible to execute the operation by synchronously driving a plurality of lift mechanisms. It can be executed only by driving.
Note that a slight error occurs in the stop position of the nursery box due to the sliding condition when lifted in this way, but this error is fixed by disposing a guide beside the path for lifting the nursery box, Can be easily corrected by sliding in contact with a fixed guide during lifting movement by one pitch.

The lift mechanism is activated in accordance with the loading of the seedling box, and it is possible to lift and regulate the position at a timing that does not make it close to the soil. The speed at which the boxes are transported can be increased, and the processing efficiency can be increased accordingly.
