Reference numeral 86 denotes a stacking completion sensor that detects that the support base 75 has placed the stacking seedling raising box A on the receiving and conveying device 74. When the stacking completion sensor 86 detects the stacking completion sensor 86, the receiving and conveying device 7
The transport motor 87 of FIG. 4 is rotated to transport the stacked seedling raising box A, and when this is detected by the unloading detection sensor 88, the support table 7 is
5 is raised to the standby position.

The relationship between the receiving frame 69 and the support table 75 is such that the receiving frame 69 lowers the lower sprocket 67 by lowering at least one seedling raising box A from a receiving position for receiving the seedling raising box A from the transfer table 1. One rotation of the receiving frame 69 returns to the standby position, but one rotation of the receiving frame 69 removes the step-stacking seedling box A on the support base 75 by the transport belt 78, and the upper step-stacking seedling box A disappears. Is set so as to coincide with the time required for the support base 75 to return to the standby position through the space between the left and right transport belts 78. That is, the receiving frame 69 puts the n-th last seedling raising box A on the (n-1) th seedling raising box A. Time required for receiving the next seedling box A to be stacked from the transfer table 1 and transferring it to the support table 75, and time required for unloading the stacked seedling box A on the conveyor belt 78 and returning the support table 75 And receiving frame 69
Is lowered as much as possible to improve the working efficiency. Therefore, the descending distance of the receiving frame 69 is longer than one seedling raising box A, but shorter than the n seedling raising boxes A. 75 is set at the same time as the return. The transfer unit 19 is connected to the receiving / conveying device 74. The transfer unit 19 is for taking out the seedling raising boxes A stacked in the seedling raising box stacking device 11 and stacking the subsequent seedling raising boxes A in the empty receiving / transporting device 74 in the seedling raising box stacking device 11. In addition, support rollers 21 are axially mounted on a pair of left and right front and rear support plates 20 at predetermined intervals. The support roller 21 is set at the same height as the transport roller 14. The support roller 2

I do. Therefore, a stop mechanism is provided in all of the seedling box automatic feeding device 6, the floor soil feeding device 7, the seed feeding device 8, the covering soil feeding device 9 and the like of the seeding transfer table 1 and the irrigation device.

[0013]

Since the present invention has the above construction, the empty seedling box A is supplied to the automatic seedling box feeding apparatus 6 located above the start end of the seeding transfer table 1, and the automatic seedling box feeding apparatus 6 transfers the seedling box. Stand 1
The seedling boxes A are supplied one by one to the transfer rollers 5 of FIG. As an example, when a predetermined number is supplied in a state of being stacked vertically on the accommodation space of the seedling box automatic feeding device 6, the automatic seedling box feeding device 6 is engaged with the seedling box A at the lowermost stage of the stacked seedling box A. The upper part engages to support the whole, then the upper engaging part protrudes and engages with the second seedling box A from the bottom, and the lower engaging part retracts to transfer only the lowermost seedling box A. Then, the lower engaging portion protrudes and the upper engaging portion retracts, and this is repeated to automatically supply the seedling raising box A. The seedling raising box A supplied to the transfer roller 5 is supplied with floor soil by the floor soil supply device 7, supplied with seeds by the seed supply device 8, and supplied with soil by the cover soil supply device 9 to complete seeding (in addition, Since the content of the seeding operation is not a requirement, the explanation is simplified, and the leveling of the floor soil and irrigation are omitted.) The seedling raising box A that has been sown is rapidly forwarded by the rapid feeding device 10 and the seedling raising box stacking device 11 is moved.
, And the seedlings are stacked vertically by the seedling box stacking device 11. In the embodiment, since the seedling transfer box 1 is provided with the seedling raising box stacking device 11 at the end of the seedling transfer table 1, a series of operations from sowing to the empty seedling raising box A and stacking the seeded seedling raising box A is performed. As it can be done continuously, improving work efficiency.

When the seedling raising box A slides on the receiving frame 69 provided on the pair of front and rear chains 68, the nursery box stacking device 11 detects the start sensor 80 and energizes the receiving frame motor 81. The chain 68 is rotated to lower the receiving frame 69. When the seedling raising box A is placed on the support base 75, the receiving frame 69 is retracted and returns to the standby position for receiving the subsequent seedling raising box A from the transfer table 1 and waits. The return sensor 82 detects that the receiving frame 69 returns to the standby position. Is detected, the power source 77 is operated to lower the support base 75. The lowering stop sensor 84 detects that the support 75 has descended by one step and the nursery box A on the support 75 has passed.
Is detected, the power source 77 is stopped. On the other hand, the receiving frame 69 returns to the standby position and receives the subsequent seedling raising box A, and the succeeding seedling raising box A overlaps the preceding seedling raising box A of the support base 75 as described above. Descend,
This is repeated to stack about 10 sheets. The stacking of the seedling boxes A is repeated, the receiving frame 69 is lowered and the nth seedling box A is stacked, and when the stacking is completed, the support base 75 is located below the receiving and transporting device 74. The stacking completion sensor 86 detects the current and energizes the transport motor 87, and causes the transporting belt 78 of the receiving and transporting device 74 to move the stacking seedling raising box A to the transfer unit 19. When the stacked seedling raising box A is carried out to the relocation unit 19, the sensor unloading detection sensor 88 provided in the relocation unit 19 detects this, and raises the support base 75 to the standby position. in this case,
The time required for unloading the stacked seedling box A to the transfer unit 19 and elevating the support base 75 to the standby position, and the receiving frame 69 stacking the nth seedling box A, and the subsequent seedling box A Of the receiving frame 69 is set so that the time required for lowering the seedlings to the support base 75 coincides, so that the support base 75 reliably supports the subsequent seedling raising box A, and Start stacking work.

As described above, since the receiving frame 69 only lowers one (one) seedling raising box A, it is possible to quickly return to the standby position, and to provide a high-speed seeding apparatus of 1,000 boxes or more per hour. Can also be stacked correspondingly. In addition, the transport belt 78 of the receiving and transporting device 74 is provided below the nursery box stacking device 11 at a narrow interval from the left and right width of the nursery box A.
The conveyor belt 78 reliably supports the stacked seedling raising box A. Further, since the support base 75 is formed to have a narrow left and right width from the left and right interval of the pair of right and left transport belts 78, the support base 75
Is lowered from the upper surface of the conveyor belt 78, so that delivery can be performed smoothly and reliably. Thus, the stacked seedling raising box A is transferred from the conveyor belt 78 to the support roller 21 of the transfer section 19, is conveyed by the rotation of the conveyor belt 78 and the rotation of the support roller 21a on the start end side, and comes into contact with the stopper 22 to be conveyed. Stopped. At this time, since the stacked seedling box A is in contact with the stopper 22, there is no problem even if the support roller 21a is driven and rotated, and the supporting roller 21a removes the stacked seedling box A from the receiving / conveying device 74 and conveys it. It stops when the rotation of the belt 78 stops. Support roller 21 of transfer section 19
When the stacking seedling box A comes into contact with the stopper 22 and the stopper 22 is brought into contact with the stopper motor 22, the extrusion motor 36 is energized, the extrusion motor 36 rotates the chain 26, and the rotation of the chain 26 causes the extruded body 27 to move onto the support roller 21. The stacked seedling raising box A is pushed out, and the pushed-out stacked seedling raising box A is transferred onto the pallet 24 on the pallet mounting table 23 provided on the side of the transfer part 19. Thus, the preceding stepped seedling raising box A extruded on the pallet 24 is pushed by the succeeding seedling raising box A and moved to the transfer section 1.
9, the pallet transport motor 52 moves when the preceding stacking seedling box A comes into contact with the pallet detection sensor 60.
To the pallet 2
When the pallet 24 advances by one row and the pallet 24 advances by one row, the transport position detection sensor 58 detects this and stops the pallet transport motor 52.

Next, when the tiered seedling box A is placed on the pallet 24 and the pallet detection sensor 60 detects the pallet, the pallet transport motor 52 is energized to advance the pallet 24, and the mounting space at the end of the pallet mounting table 23 is set. When the trailing end of the pallet 24 passes through the drive-rotating transport roller 51, the transport is stopped, and the subsequent pallet 24 is transported by the rotating transport roller 51. When the front end reaches the reference position detecting sensor 57, this is detected and the pallet transport motor 52 is stopped, and the stepped seedling raising box A is transferred onto the succeeding pallet 24. Is transported by a forklift to a desired position such as a greenhouse called a germination room or a seedling placement place. The pallet 24 is placed on the starting end side of the pallet placing table 23 by a forklift, and when a pallet transport motor 52 is energized by a manual switch, the pallet 24 is transported by the drive rotation transport roller 51 and reaches the side of the transfer section 19. The push-out motor 36 is stopped by being detected by the position detecting sensor 57, and the pallet 24 is then moved to the empty space on the starting end side of the pallet mounting table 23 by a forklift.
Is placed. The transfer unit 19 has the support rollers 21 arranged side by side. Of these, the support rollers 21a on the start end side are configured to be driven to rotate by receiving the rotation of the transport belt 78. Since the stacked seedling raising box A is continuously transported by the support roller 21a at the same transport speed as the transport belt 78 of the transport device 74, the transport belt 7
8 and the support roller 21a can be smoothly and reliably transferred, and the transfer unit 19 does not need to be provided with a rotation transmission mechanism for only the support roller 21a. Therefore, the configuration is simplified, and only the last support roller 21a is driven. There is no problem even if the seedling raising box A is pressed against 22.

Since the tiered seedling box A is pushed out to the pallet mounting table 23 in a direction crossing the transport direction of the support roller 21, the tiered seedling box A and the support roller 21 come into line contact with each other to reduce the movement resistance. Move less. The extruded body 27 that pushes out the stacked seedling raising box A is fixed to the pair of front and rear chains 26 and rotates the pair of chains 26, so that the configuration is simple and inexpensive. In addition, since the chain 26 is supported by the chain support rail 34, the extruded body 27 is reliably moved. In addition, since the lower surface of the extruded body 27 is located above the upper surface of the support roller 21, the extruded body 27 can push out the stacked seedling box A without interfering with the support roller 21. The support roller 21 is mounted on the front and rear support plates 20 arranged on the left and right sides.
Is formed, the chain 26 and the chain support rail 34 are arranged in the cutout 33. That is, since the transport mechanism is configured by arranging the left and right support rollers 21 side by side in the front and rear direction, the transfer mechanism is provided without interfering with the rotation mechanism of the extruded body 27 extruding in the cross direction. The support plate 20 is supported, and a simple and rational configuration can be achieved as a rotation mechanism by the pair of rotation shafts 29 and the drive rotation shaft 31. The support roller 21 on the pallet mounting table 23 side is shortened due to the presence of the drive rotation shaft 31 as a rotation mechanism of the chain 26, but the upper end of the front and rear support plate 20 on the pallet mounting table 23 side and the pallet Since the sliding plate 44 is provided between the mounting table 23 and the position other than the position above the chain 26, the gap between the supporting roller 21 and the pallet 24 is eliminated, and the transfer of the stacked seedling raising box A is performed smoothly. I have to.

The extrusion motor 36 automatically reverses after a predetermined time has elapsed after the extruded body 27 has extruded the step-growing seedling box A, so that it is simply reversed through a delay circuit. Automate. Since the pallet mounting table 23 is arranged on the side of the transfer section 19 so as to convey the pallets 24 in parallel with the transfer direction of the seedling raising box A, the tiered seedlings pushed out by the transfer section 19 are arranged. Box A
Is efficiently placed on the pallet 24 and the pallet 2
4 facilitates supply and removal. The pallet 24 is transported by a transport roller 51 driven and rotated by a pallet transport motor 52. Since the pallet transport motor 52 is controlled by a sensor, it can be a fully automatic continuous operation except for the supply and unloading of the pallet 24. .
