An overlaying device 10 is provided at the end of the sowing transfer stand 1. The stacking apparatus 10 stacks the sowed seedling containers A in two upper and lower stages, and transports the seedling containers A that have been stacked in two stages to a seedling device (nursery house) 12 by means of a transporting carriage 11, and seeded two-stage seedlings The container A is carried into the seedling raising device 12 and raised for a predetermined period.
Therefore, sowing work and seedling work for obtaining seedlings to be transplanted to a small field can be performed continuously, thereby saving labor.
The stacking apparatus 10 includes a fast-forwarding transfer unit 15 and a fast-forwarding transfer unit 15 connected to the terminal end of the seeding transfer table 1 and a stacking transfer unit 16 following the fast-forwarding transfer unit 15.
The fast-forwarding transfer unit 15 is provided with fast-forwarding means 17. The fast-forwarding means 17 is constituted by a roller or a belt, and in the embodiment, it is constituted by a pair of left and right fast-forwarding belts 18.

The fast-forward belt 18 is wound around a pair of front and rear pulleys (not shown), and a gear 22 is provided on the rotation shaft 21 of the pulley on the lower side (front side) in the transfer direction. The driving force of the transfer motor 23 is transmitted to the gear 22.
The stacking transfer unit 16 is provided with transfer means 24 for transferring the seedling container A stacked in two stages onto the transfer table 11. The transfer means 24 is constituted by a roller or a belt. In the embodiment, the transfer means 24 is constituted by a pair of left and right transfer belts 25 and a transfer roller 25A.
The fast-forward belt 18 is driven and rotated by a transfer motor 23 to fast-forward and transfer the preceding seedling container A to form an interval with the subsequent seedling container A, and to set an interval with the preceding seedling container A. While the succeeding seedling raising container A passes, an upper and lower support frame 27 described later is driven by a superposition motor 28 to lift the preceding seedling raising container A upward and wait.

  That is, the fast-forwarding belt 18 of the fast-forwarding transfer unit 15 fast-forwards the seeded seedling raising container A delivered to the fast-forwarding transfer unit 15 to form an interval with the subsequent seeded seedling raising container A (FIG. 16I). ), While the second seedling container A passes through the interval between the first seedling container A and the second seedling container A, the seedling has been sown by the upper and lower support frame 27 of the transfer unit 16 for overlaying The first seedling raising container A is once lifted and supported, and while the third seedling raising container A passes through the interval between the second seedling raising container A and the third seedling raising container A, the The seeded first seedling container A that has been lifted by the upper and lower support frame 27 is stacked on the second seedling container A (FIG. 16C), and then the two-stage stacked seedling container A is taken out and the third sheet is transferred. The seedling container A is fast-forwarded (FIG. 16D), and this operation is repeated.

Therefore, the interval between the preceding seedling container A and the succeeding seedling container A is set longer than the time required for the preceding seedling container A to rise and the time required for the preceding seedling container A to descend, and is overlapped in two stages ( In addition, each figure of FIG. 16 shows an outline and is not limited to the structure of the space | interval between the preceding seedling raising container A shown in FIG. 16, and the succeeding seedling raising container A).
The structure for lifting the seedling raising container A is configured by a pair of left and right upper and lower support frames 27. The vertical support frame 27 has mounting portions 30 at the front and rear, and the mounting portions 30 are connected by a vertical plate portion 31. The vertical plate portion 31 is provided with a substantially horizontal support portion 33 following the arc portion 32.
For this reason, the vertical plate portion 31, the arc portion 32, and the support portion 33 improve the rigidity of the upper and lower support frame bodies 27.
The upper and lower support frame 27 is attached to its attachment portion 30 to a pair of front and rear attachment arm portions 36 of the vertical movement body 35 so as to be rotatable by a shaft 37. The vertical moving body 35 is attached to a pair of vertical support shafts 39 provided on the frame 38 of the stacking transfer section 16 so as to be slidable in the vertical direction. Long vertical guide holes 42 in the transfer direction of the seedling raising container A are formed in the vertical plate portions 40 of the left and right vertical moving bodies 35, respectively. The guide holes 42 are fitted with rollers 43 whose axial centers are in the horizontal direction. The roller 43 is rotatably mounted on the tip of the arm 44 by a left and right shaft 45.

The base of each arm 44 is mounted on the vertical frame 46 of the frame 38 of the stacking transfer unit 16 by a left and right shaft 47, and a gear 48 is provided on the shaft 47. A chain 51 is hung between each gear 48 and an intermediate gear 50 provided on an intermediate shaft 49 in the left-right direction. A driven gear 52 is provided on either the left or right side of the intermediate shaft 49, and a chain 54 is wound around the driven gear 52 between the output gears 53 of the superposition motor 28.
The intermediate shaft 49 is mounted on the frame 38 of the stacking transfer unit 16 so as to be positioned above the upper surface of the seedling raising container A stacked in two upper and lower stages.
A pair of left and right receiving plates 55 are attached to the shaft 56 so as to be movable up and down. Reference numeral 57 denotes a spring that urges the receiving plate 55 so as to always move upward. The spring 57 supports the single seedling container A, but is configured to be elastic to lower the receiving plate 55 when the two-stage seedling container A is placed.
58 is a through-hole formed in the receiving plate 55 through which the upper and lower support frame bodies 27 pass.

That is, the receiving plate 55 receives the seedling raising container A at the upper receiving position, and when the first seedling raising container A is lowered to be stacked in two stages, the receiving plate 55 is lowered to transfer the two-stage stacked seedling container A to the transfer means 24. Place on top.
When the superposition motor 28 is energized, the roller 43 and the arm 44 rotate about the crossing direction with respect to the transfer direction of the seedling container A, and this rotational motion is moved up and down by the roller 43 and the guide hole 42 of the vertical moving body 35. Therefore, the vertical support frame 27 can be moved up and down in a small working space.

As shown in FIG. 10, the upper and lower support frame 27 waits below the receiving plate 55, comes into contact with the bottom surface of the seedling container A on the receiving plate 55, lifts the seedling container A as it is, and the seedling container A is once lifted. In this state, when the next seedling container A is received on the lower receiving plate 55 and is lowered onto the succeeding seedling container A that has received the raised seedling container A, it is evacuated to form two layers.
When the seedling containers A are stacked in two stages, the transfer belt 25 transfers (unloads) the seedling containers A stacked in two upper and lower stages to the transfer table 11, and the upper and lower support frame 27 is supported from the retracted position by its own weight. Return to.
The transfer table 11 is provided with a plurality of support legs 61 at predetermined intervals on a pair of left and right frames 60, and is installed between the seedling raising device 12 and the seeding transfer table 1. A plurality of transport rollers (not shown) are provided on the frame 60 at a predetermined interval. All transport rollers are free to rotate and not driven.

Further, a plurality of transfer tables 11 having a predetermined length may be prepared, and the plurality of transfer tables 11 may be connected depending on the distance between the sowing transfer table 1 and the seedling raising device (nursing house) 12.
Thus, as described above, in the stacking apparatus 10, the fast-feed belt 18 of the fast-forwarding transfer unit 15 fast-forwards the seeded seedling raising container A delivered to the fast-forwarding transfer unit 15, and the subsequent seeded seedling raising container A Between the first seedling raising container A and the second seedling raising container A while the second seedling raising container A passes therethrough, The first seedling container A that has been sowed by the support frame 27 is once lifted and supported to stand by, and the interval between the second seedling container A and the third seedling container A is set to the third seedling container A. , The seeded first seedling container A that has been lifted by the upper and lower support frame 27 is stacked on the second seedling container A, and then the two-stage stacked seedling container A is unloaded and three The fast-feeding of the single seedling seedling container A is simultaneously performed, and this operation is repeated (FIG. 16). .

The transfer motor 23 and the stacking motor 18 that perform this work perform on / off control by switches that are detection means provided in the stacking apparatus 10.
The arrangement of each switch is arbitrary, but as an example, when the seedling raising container A intrudes to a predetermined position on the receiving plate 55 at the standby position of the stacking transfer unit 16, an entry detection for detecting this intrusion. A switch 66 is provided on the frame 16 of the stacking transfer unit 16.
That is, the transfer motor 23 of the fast-forward transfer unit 15 is energized before the overloading operation is started, and drives the fast-feed belt 18 of the fast-feed means 17.
Therefore, when the seedling container A is transferred from the seeding transfer table 1 to the fast-forwarding transfer unit 15 of the overlaying apparatus 10, the preceding seedling container A is fast-forwarded and an interval is formed between the seedling container A and the subsequent seedling container A. When the seedling raising container A that has entered the predetermined position on the receiving plate 55 at the standby position and contacts the entry detection switch 66, the transfer motor 23 is temporarily stopped (FIG. 11).

When the preceding seedling container A comes into contact with the entry detection switch 66, the stacking motor 18 is energized, and the upper and lower support frames 27 raise the seedling container A to a height at which the next seedling container A can enter (FIG. 11, FIG. 12).
An upper standby detection switch 67 is provided at a predetermined position of the stacking transfer unit 16 to indicate that the preceding seedling container A has risen to a height at which the subsequent seedling container A can enter (FIG. 12).
Further, the receiving plate 55 and the upper and lower support frames 27 are lowered below the standby height position at a predetermined position of the frame 38 of the stacking transfer unit 16, and the two-stage stacked seedling container A is transferred onto the transfer means 24. Is placed, a descent detection switch 68 is provided.
When the vertical support frame 27 comes into contact with the lowering detection switch 68, it shifts from a lowering movement to an ascending movement, rises to a standby height position (upward movement position of the receiving plate 55), and comes into contact with the lower standby detection switch 69.

That is, the vertical support frame 27 moves up and down as the roller 43 of the arm 44 moves circularly about the shaft 47. The positional relationship between the vertical support frame 27 and the roller 43 will be described. The slightly raised position is defined as a lower standby position where the vertical support frame 27 receives the seedling container A (FIG. 10), and is positioned slightly below the receiving plate 55 at the reception position. 27 so that the lower standby detection switch 69 is in contact with it.
Therefore, as shown in FIG. 10, when only the lower standby detection switch 69 is in contact, the lower standby state without the seedling raising container A is entered.

Next, as described above, when the seedling container A is transferred to the fast-forwarding transfer unit 15 and fast-forwarded and enters the predetermined position on the receiving plate 55 at the standby position, the entry detection switch 66 that detects this intrusion is applied. Contact is made (FIG. 11), the transfer motor 23 is temporarily stopped, the superposition motor 28 is energized, and the arm 44 and the roller 43 rotate counterclockwise as shown in FIGS. When the seedling container A comes into contact with the upper standby detection switch 67, the energization of the overlapping motor 28 is temporarily turned off.
At this time, when the upper and lower support frame 27 is raised and the preceding seedling container A leaves the entry detection switch 66, the transfer motor 23 that has been temporarily stopped is energized and the subsequent seedling container A is fast-forwarded (from FIG. 11 to FIG. 11). The preceding seedling container A is rising to 12).

Next, when the entry detection switch 66 detects the entry of the succeeding (second) seedling container A, which is the lower one of the upper and lower stages, into the receiving plate 55, the upper standby detection switch 67 and the entry detection switch 66 simultaneously. Then, the power is supplied again to the overlapping motor 28, and the arm 44 and the roller 43 are rotated counterclockwise to lower the vertical support frame 27.
At this time, the upper and lower support frames 27 are in contact with the lower standby detection switch 69 at the lower standby position, but the arm 44 and the upper and lower support frames 27 are further lowered, and the upper and lower support frames 27 are in contact with the lower detection switch 68.

Accordingly, since the entry detection switch 66, the lowering detection switch 68, and the lower standby detection switch 69 are in contact with each other at the same time, the rotation of the stacking motor 28 is stopped, and the transfer motor 23 is energized at the same time, so The container A is carried out to the transfer table 11 for conveyance.
When the two-stage stacked seedling container A is carried out, the energization motor 28 is energized again, the roller 43 located at the lowest position is rotated up to the standby position, and the vertical support frame 27 is detached from the lowering detection switch 68. Thus, the energization to the superposition motor 28 is cut off at the standby height.
The fast-forwarding transfer unit 15 is provided with a transfer detection switch 65 for detecting the transfer of the seedling container A, and the transfer is performed while the entry detection switch 66, the lowering detection switch 68, and the lower standby detection switch 69 are in contact with each other at the same time. When the detection switch 65 detects the transfer of the seedling container A to the fast-forwarding transfer unit 15, all the operations of the sowing transfer stand 1 are stopped.

(Operation of Example)
The seeding transfer stand 1 is installed at a predetermined position in the vicinity of the seedling raising device 12 for raising the seeded seedling raising container A for a predetermined period, and the start end portion of the fast-forwarding transfer portion 15 of the overlaying apparatus 10 is connected to the end of the sowing transfer stand 1. The starting end of the transfer table 11 is connected to the end of the transfer unit 16 of the stacking apparatus 10, and the end of the transfer table 11 is installed in the vicinity of the carry-in entrance of the nursery device 12.
Next, an empty seedling container A is supplied to the starting end of the sowing transfer stand 1, and the seedling container A being transferred is supplied with floor soil below the floor soil supply device 2, irrigated, and seed supply device 3. The seed supply is received below the cover, and the cover is supplied below the cover supply apparatus 4.

The seedling container A which has been sowed and transferred to the end of the seeding transfer table 1 is transferred to the fast-feed belt 18 of the fast-feed transfer unit 15 of the stacking apparatus 10, and the fast-feed belt 18 is driven by the already-energized transfer motor 23. Then, the seedling container A is fast-forwarded and transferred, and an interval is formed between the seedling container A and the subsequent seedling container A.
When the first seedling container A is transferred onto the receiving plate 55 by the fast-forwarding belt 18 and enters the stacking transfer unit 16, the seedling container A contacts the entry detection switch 66 and energizes the stacking motor 28. The vertical support frame 27 is raised.
At this time, the transfer motor 23 is temporarily stopped by the contact between the seedling raising container A and the entry detection switch 66.

When the vertical support frame 27 raises the first seedling container A to a predetermined height, the seedling container A comes into contact with the upper standby detection switch 67, the energization of the stacking motor 18 is once cut off, and the transfer motor 23 is simultaneously turned off. Re-energize.
While the first seedling container A is supported by the upper and lower support frames 27, the subsequent second seedling container A is transferred to the fast-feed belt 18 of the fast-feed transfer unit 15 of the stacking apparatus 10, and the fast-feed belt 18. Thus, when the second seedling container A enters the receiving plate 55 of the stacking transfer unit 16 and contacts the entry detection switch 66, the stacking motor 28 is energized and the vertical support frame 27 starts to descend. .

In detail, when the first seedling container A starts to rise by the upper and lower support frames 27 and the seedling container A is separated from the entry detection switch 66 and is in a non-contact state, the transfer motor 23 is re-energized. In addition, the rising time of the first seedling container A can be included in the interval with the subsequent seedling container A, thereby improving work efficiency.
Next, when the first seedling container A is stacked above the second seedling container A by the lowering of the upper and lower support frame body 27, the receiving plate 55, the two-stage stacked seedling container A, and the upper and lower support frame body 27 are moved downward. When the standby detection switch 69 is touched, and the receiving plate 55, the two-stage stacked seedling container A, and the upper and lower support frame 27 are lowered and come into contact with the lowering detection switch 68, the stacking motor 18 is deenergized, Overlaying ends.

  At this time, since the lower second seedling container A is in contact with the entry detection switch 66, the transfer motor 23 is in a stopped state, and the receiving plate 55, the two-stage stacked seedling container A, and the upper and lower support frame 27 When the descent detection switch 68 comes into contact with further descent, the two-stage stacked seedling container A is placed on the transfer means 24, and all of the entry detection switch 66, the descent detection switch 68, and the lower standby detection switch 69 are in contact with each other. In addition, the energization of the stacking motor 18 is cut off, the energization of the transfer motor 23 is carried out, and the two-stage stacked seedling container A is carried out from the transfer transfer unit 16 to the transfer table 11 for transfer, and at the same time, the fast-forward transfer unit The third subsequent seedling container A from 15 is fast-forwarded.

In this way, the seedling raising seedling container A sowed on the seeding transfer stand 1 is stacked in two upper and lower stages by repeating the above operation, and is carried out.
Accordingly, the two-stage stacking of the second seedling container A and the carrying-out of the two-stage seedling container A to the first seedling container A are spaced from the subsequent seedling container A caused by fast-forwarding by the fast-forward belt 18. Is performed while the subsequent seedling raising container A moves.
In addition, since the vertical support frame 27 raises and lowers the seedling container A by rotating the arm 44 and the roller 43 once, the control can be easily and reliably performed, and the setting of the arrangement of each switch is also possible. It becomes easy.
Note that the upper and lower support frame bodies 27 have the front and rear attachment portions 30 attached to the pair of front and rear attachment arm portions 36 of the vertical movement body 35 so as to be rotatable by the shaft 37. When the first seedling container A is stacked above the eye seedling container A, the upper and lower support frame body 27 comes into contact with the side wall of the second seedling container A and retracts, and descends in the retracted state. Passes through the lower surface of the lower seedling raising container A, it returns to its supporting position by its own weight rotation.

In addition, the seedling raising seedling container A transferred from the seeding transfer table 1 is transferred onto the receiving plate 55, contacts the entry detection switch 66, energizes the superposition motor 28, and leaves the receiving plate 55 below and moves up and down. The support frame 27 rises from a position below the receiving plate 55 and comes into contact with the lower surface of the seedling raising container A, and the upper and lower support frame 27 raises the raising seedling container A as it is, leaving the receiving plate 55 below.
Therefore, the certainty of the support of the lower surface of the sowing seedling raising container A by the upper and lower support frame 27 is improved.

When the second seedling container A enters the receiving plate 55 below the first seedling container A held by the upper and lower support frame 27, it is supported by the receiving plate 55, and further enters and detects entry. The switch 66 contacts the energizing motor 28 and starts to descend the vertical support frame 27.
When the first seedling container A overlaps above the second seedling container A due to the lowering of the upper and lower support frame body 27, the upper and lower support frame body 27 comes into contact with the upper surface of the side wall of the second seedling container A and retracts. Rotate to position.

  Since the elasticity of the spring 57 urging the receiving plate 55 is set so as not to support the two seedling containers A, the first seedling container A overlaps the second seedling container A. Then, the receiving plate 55 lowers the two-stage stacked seedling container A and comes into contact with the lower standby detection switch 69, and further the two-stage stacked seedling container A descends, and the transfer belt 25 and the transfer roller 25 </ b> A of the transfer means 24. When placed on top, it comes into contact with the lowering detection switch 68, the energization of the stacking motor 18 is cut off, the upper and lower two-stage stacking is completed, the energization of the transfer motor 23 is performed, and the stacking transfer unit 16 The two-stage stacked seedling container A is carried out to the transfer table 11 for transfer.

Thus, since the receiving plate 55 is placed on the transfer belt 25 and the transfer roller 25A of the transfer means 24 only when the seedling raising container A is stacked in two stages, the operation can be reliably performed.
Therefore,


Thus, the above operation is repeated and stacked in two upper and lower stages, sent out to the transfer table 11 for transfer, and the two-stage stacked seedling container A sent to the transfer table 11 for transfer is transferred to the seedling container by the transfer table 11 for transfer. The seedling raising container A is carried to the seedling raising device 12.
In this case, the transfer table 11 is provided with a plurality of support legs 61 at predetermined intervals on a pair of left and right frames 60 and is installed between the seedling raising device 12 and the transfer table 1 for seeding. A plurality of rollers 62 are provided at predetermined intervals, and all of the transport rollers 62 are freely rotated and are not driven to rotate. Therefore, the seeded two-stage seedling container A carried out by the transfer unit 16 for overlaying is preceded by two seeded seedling containers A The stacked seedling container A is pushed, the seeded two-stage stacked seedling container A is sent in order, and reaches the end of the transfer table 11 for conveyance.

The seedling raising seedling container A sent to the terminal end of the transfer table 11 is carried into the seedling raising device 12 and raised for a predetermined period.
Therefore, the transfer table 11 does not require any drive device and can be configured to be extremely lightweight.
Therefore, installation of the transfer table 11 is easy, the selection range of the installation location of the sowing transfer platform 1 and the installation location of the seedling device 12 can be expanded, and the entire sowing and seedling work is facilitated.

In addition, the seedling raising container A sowed by the sowing transfer stand 1 is automatically stacked in the upper and lower stages by the stacking device 10 as it is, and when the stacking is finished, the seedling container A is automatically raised by the transporting transfer stand 11. Since it is transported to the vessel 12, it is freed from the work of transporting the heavy sowing seedling raising container A, and the reduction of sowing and raising seedling work is improved.
In addition, the transporting platform 11 can transport the preceding seedling container A by the subsequent seedling container A sent out from the stacking apparatus 10, although the seedling container A is fast-forwarded by the fast-forwarding means.
Therefore, when the seeding transfer table 1, the stacking device 10, and the transfer table 11 are installed, an operator for supplying an empty seedling container A to the seeding transfer table 1 at the start end of the seeding transfer table 1, and the transfer Thus, two workers who carry the seedling container A into the seedling raising device 12 at the end of the transfer table 11 can perform work, and labor costs can be reduced.

  Therefore, even in a small-scale work place, it is possible to perform continuous sowing work at a low cost, shorten the work time required for the sowing work, and free from the heavy sowing seedling container A carrying work. And the two workers work of the importer is also possible, and the labor cost can be reduced.
