SUMMARY OF THE INVENTION The above-mentioned JP-A-63-15
The method described in Japanese Patent No. 4527 has a problem that this operation is not easy because the transportation of the tiered seedling boxes taken out to the relocation part is not taken into consideration. That is, when the seedling box is sown, there is 6 to 8 kg of one seedling, and when ten seedlings are stacked,
It weighs 60-80 kg and is not easy to transport. For this reason, it is difficult to lift a product stacked on a low cradle. In this regard, if the transfer table is stacked upward at the end of the transfer table, there is no need to lift it, but since it is stacked in the frame, removal is difficult. Also, since the tiered seedling boxes are heavy, it is difficult to transfer them to the table of the transport lift device. Similarly, the loading and unloading of the transport system onto the cart is not easy. Also, the seedling box is sown on the upper surface, thinly covered with soil, and has a rib on the bottom surface of the seedling box. Since the seedling boxes are piled up, the seedling boxes that have been stacked cannot be shifted sideways, and in this regard, a general physical distribution system cannot be used. Also, the place to transport the nursery box is
Since the floor is a ground for placing soil, the floor surface is not horizontal, and a general physical distribution system cannot be used in this regard.

Receiving the supply, the seedling transfer table 2 is slid and placed on the right and left receiving frames 9 of the seedling raising box stacking device 8 from the terminal end, and when the left and right receiving frames 9 receive one seedling raising box A, the chain 10 is rotated to descend. Then, the other left and right receiving frames 9 stand by at the receiving position, and the left and right receiving frames 9 on which only one seedling raising box A is placed immediately descend to place the seedling raising boxes A on the receiving tray 12, and the other left and right receiving frames are placed. 9 receives the subsequent seedling box A, descends, hits the seedling box A already placed on the receiving tray 12 and turns upward and retreats, and the subsequent seedling box A is already placed on the receiving tray 12. Are stacked on the seedling raising box A, and when the predetermined number of sheets are stacked on the receiving tray 12, -11 is rotated to transfer the tiered seedling raising box A on the receiving tray 12 to the transfer part 13 and the next seedling raising box A is laid on the receiving tray 12, and the tiered seedling raising seedling A on the transfer part 13 is The seedling raising box A which has been sown is taken out from the relocation part 13 by the stepped raising seedling box raising and conveying device 16 described later, and the seedling raising box A is stacked.

Therefore, only by supplying a plurality of empty seedling raising boxes A to the automatic feeding device 3 of the seeding transfer table 2, continuous operations can be performed until the seeded raising seedling boxes A are stacked. In addition, since the transfer table 2 for sowing of the sowing apparatus 1 is set to a height at which the operator can operate the automatic supply device 3 to the soil supply device 6 in a standing position, the work can be performed very easily. I can do it. Also,
Since the seedling raising box stacking device 8 stacks the seedling raising boxes A by lowering them with the left and right receiving frames 9, it can be configured with a mechanism for supporting one seedling raising box A, and the strength and other configurations are simple and take up little space. However, the end of the relocation unit 13 faces the beginning of the step-stacking seedling box ascending and transporting device 16 slightly lower than the transfer unit 13.
Is transferred (manual operation or the transfer force of the transfer unit 13). That is, the receiving stand 12 of the seedling box stacking device 8 is lower than the seeding transfer table 2 according to the work height of the worker.
It is not easy because it is taken out from the transfer unit 13, but the starting end of the stacking seedling box ascending and transporting device 16 is located at the transfer unit 1.
Since the height is the same as that of No. 3, it can be easily moved by pressing the box A.

Further, the stacking raising seedling box raising and conveying device 16 is formed by a driving and rotating conveying belt 21. The terminal of the conveying belt 21 is the same as or slightly higher than the upper surface of the terminal mounting table 17, so that the terminal mounting It is conveyed toward the mounting table 17, the height position is raised during the conveyance, and the stepped seedling raising box A is mounted on the terminal mounting table 17. Next, when the subsequent step-stacking seedling box A is unloaded from the relocation unit 13, the step-stacking seedling box ascending and transporting device 16 places the step-stacking seedling box A on the mounting table 17 for the terminal. Presses the preceding tiered seedling raising box A. Therefore, the tiered seedling raising box A carried out from the transfer part 13 having a low height can be placed on the terminal mounting table 17. Also, the end of the conveyor belt 21 is
Since it is formed in a horizontal portion with a longer interval, the step-stacking seedling box A that is raised obliquely is changed to a horizontal position, so that it can be easily slid toward the terminal mounting table 17 to move over. Then, the plurality of step-stacking seedling boxes A are placed on the terminal mounting table 17 by the step stacking seedling box ascending and transporting device 16, and the step stacking seedling boxes A on the terminal mounting table 17 are connected to the terminal mounting table 1.
7 is slid on the table 28 of the lift device 25 provided in the vicinity of 7 so as to be transferred to the transport carriage 32.

The carriage 32 runs on the traveling rail 31 by a power source 35 and stops automatically at a predetermined position. In the embodiment, the derivative 38 provided at each predetermined position is automatically controlled on the basis of a signal detected by the travel sensor 37, travels automatically on the travel rail 31, and automatically stops at the predetermined position. Next, the one-side engaging portion 63 provided on the transporting carriage 32 is engaged with the other-side engaging portion 64 provided on the supply truck 49. In this state, the step on the transporting carriage 32 is The stacking seedling box A is replaced with the supply cart 49, and the transport cart 32 is returned to the original place. Then, the supply cart 49 travels on the traveling rail 31 extending to the placement nursery 44 in the greenhouse 43 as it is, and the table 53 of the supply cart 49 is
The fork portion 62 faces between the left and right seedling box support members 119 of the seedling box supply device 48, which will be described later.
When the one-side engaging portion 66 provided on the front side of the tray is placed on the tray 56, and then the stepped seedling raising box A on the placing part 56 is pushed toward the fork part 62, the stepped seedling raising box A becomes the seedling box feeding device 48. Is located in the storage space.

In the above case, the transporting carriage 32 is provided with a power source 35 and a battery 40 on a traveling frame 33 having a predetermined left and right width. Get higher. On the other hand, in order to increase the number of stacked units in the transfer unit 13 and to reduce the impact of descent when laying the nursery box A in the nursery box parallel device 46, it is preferable to set the height as low as possible. When using the transport trolley 32, the height will not match both when loading and unloading the transport trolley 32,
When loading on the transport trolley 32, stepped seedling raising box raising transport device 1
6 easily raise while transporting the stacked seedling raising box A,
When lowering, lower the table on the supply cart 49 and then on the table 5
By the inclination of 3, the height is reduced in accordance with the seedling box supply device 48. Therefore, the relocation unit 13, the stepped raising seedling box raising and transporting device 16, the terminal mounting table 17, and the transporting cart 32
And the supply cart 49, so that the cost is reduced.

The traveling frame 33 of the carriage 32
Since the horizontal axis rollers 41 are juxtaposed on the upper surface of the transfer member 13, it is easy to push the horizontal axis rollers 41 from the rollers 14 of the transfer unit 13. Therefore, the box-raising seedling box A can be taken out and transported without the need for manual lifting. In addition, the transport trolley 3
Since the second operation panel 39 is arranged at a predetermined interval laterally from the traveling frame 33, it is also possible to change the direction of the stacked seedling raising box A, and it does not affect the unloading of the seedling box A at all. In addition, operability and workability are improved. Since the stacked seedling raising box A taken out of the relocation unit 13 is temporarily stored on the terminal mounting table 17 instead of being directly mounted on the transport cart 32, the capacity of the seedling box paralleling device 46 and the transfer for sowing are set. Even if there is a difference in the capacity of the table 2, work can be performed continuously.

In addition, since the height of the terminal mounting table 17 and the height of the transport trolley 32 are made to be the same, it is extremely troublesome because the lift device 25 is provided between the terminal mounting table 17 and the transport trolley 32. Easy to do. In addition, since one set of tiered seedling raising boxes A is moved up and down by the lift device 25 without moving the entire mounting table 17 for the terminal, the lift device 25 can be manufactured at low cost (in the embodiment, a cylinder is used). However, it can also be performed by a cam mechanism, and the cost is further reduced). Then, since the transfer cart 32 is moved to the supply cart 49 traveling on the traveling rail 31, the stacked seedling box A can be easily obtained.
Can be transported. In addition, since the supply cart 49 has the handle 55 on the side, the stacking seedling raising box A can be easily moved from the transport cart 32 at the rear of the supply cart 49. in this case,
When the supply carriage 49 is provided with a horizontal-axis transport roller, the transfer can be further facilitated. Thus, since the supply cart 49 has the table 53 formed in an overhang shape with respect to the traveling vehicle body 50, the supply is easy without the frame 77 of the nursery box supply device 48 being in the way. Further, since the table 53 is formed narrower than the left and right width of the seedling raising box A, it can be easily inserted between the left and right seedling raising box supports 119. In addition, the supply cart 49 is a traveling wheel 5 of the traveling body 50.
1 is placed on the running rail 31 of the placement nursery 44, so that if the seedling box supply device 48 is positioned with respect to the seedling box paralleling device 46, which will be described later, the traveling vehicle body 50 only needs to be moved forward. The fork 62 can be inserted between the seedling box supports 119.

Although the operation of the seedling box supply device 48 will be described later in detail, the seedling box support 1 of the seedling box supply device 48 will be described later.
Since 19 is provided below the support arm 118 fixed to the shaft cylinder 116 having a cantilever structure, the front side of the seedling box supply device 48 is opened, and the supply by the supply cart 49 is further facilitated. Therefore, the fork part 62 is connected to the seedling box support 1.
19, the left and right seedling raising box supports 119 are raised, and the seedling raising box support 119 is engaged with the lower surface of the lowermost seedling raising box A of the stacked seedling raising boxes A. Is raised, the table 53 can be pulled out backward, and the supply of the tiered seedling box A becomes very easy. in this case,
Since the nursery box support 119 is on standby at a position above the frame 77, the fork 62 of the table 53 is pulled out without interfering with the frame 77. Thus, the seedling raising box A supplied to the seedling raising box supply device 48 is supplied to the placement moving frame 70 of the seedling raising box paralleling device 46 by the seedling raising box supply device 48, and is laid on the left and right sides of the traveling rail 31. When one line is laid, the traveling frame 47 is advanced. Therefore, a series of operations from sowing to an empty nursery box A to laying in the placement nursery 44 can be performed continuously, and the operation can be simplified, so that it can be performed by a small number of people.

Although the configurations of the seedling box supply device 48 and the seedling box paralleling device 46 are not essential, the operation of the embodiment will be described. The traveling frame 47 is provided so as to be able to travel on the traveling rail 31 in the front-rear direction of the placement nursery 44 provided in the greenhouse. The relationship between the nursery box supply device 48 and the traveling rail 31 is as follows. The seedling box supply device 48 forms a seedling box supply space having an area for accommodating one seedling box A in plan view.
Is formed longer than the interval between the running rails 31 by an interval L. When the seedling raising box A is supplied in a stacked state in the stacked space above the frame body 77, as shown in FIG. As described above, the seedling box supply device 48 is moved to the right by the interval L because the placement moving frame 70 moves to the right (FIG. 16).
B) When a predetermined position is reached, the lower side surface on the opposite side corresponding to the other side surface 79 of the seedling box supply device 48 is moved to the projection 8 for stopping movement.
The lateral movement stops upon contacting the position No. 3. Motor 1 in this state
27, and the gearbox 1 is driven by the motor 127.
26, the pinion gear is engaged with the rack groove 124 of the vertical movement shaft 125 to lower the vertical movement shaft 125, and the vertical movement shaft 125 lowers the vertical movement engagement plate 123, and the vertical movement engagement plate 123 Moving frame 11 supported via moving frame support 122
2 is lowered, and the entire left and right support arms 118 are lowered by the lowering of the moving frame 112.

That is, most of the load applied to the seedling box support 119 acts to lower the support arm 118, but a small load acts to rotate the support arm 118 outward. As a result, the engagement shaft 121 acts so as to rise, and the vertical movement engagement plate 123 provided on the vertical movement shaft 125 is located above the engagement shaft 121. , And is in an immobile state, and this state is maintained without opening the support arm 118. At this time, since the spring 131 is provided between the engagement shafts 121, the support state of the support arm 118 is more reliably held. next,
When the lower seedling raising box A is placed on the placement moving frame 70 of the seedling raising box paralleling device 46 to be described later, the moving frame 112 comes into contact with the stopper 130 to stop the downward movement of the moving frame 112. The moving frame support portion 122 is separated below the upper horizontal frame 115, and the vertical moving shaft 125 is further lowered, and the vertical moving engaging plate 123 pushes the engaging shaft 121 from above.
Numeral 21 is pivoted downward about the axis 117, support arm 118 is pivoted outward around the axis 117, and the seedling box support 119 of the support arm 118 is the lower surface of the seedling box A at the lowermost stage (in the embodiment, the seedling box A Evacuate from the collar.

The timer plate 132 comes into contact with the upper end surface of the timer longitudinal axis 134 due to the lowering of the support arm 118, and the timer longitudinal axis 134 descends as it is against the elasticity of the spring 136. When the seedling raising box support 119 of the support arm 118 is opened outward, the engagement hole 133 of the timer plate 132 faces above the timer longitudinal axis 134, and the timer longitudinal axis 134 is in the engagement hole 133 by the elastic force of the spring 136. Projecting upward through Timer longitudinal axis 134 is engaging hole 1
33, the motor 127 is rotated in the reverse direction, the vertical movement shaft 125 moves upward, and the vertical movement engagement plate 123 comes into contact with the lower surface of the moving frame support portion 122 of the moving frame 112 and moves upward. As described above, since the timer longitudinal axis 134 protrudes upward in the engagement hole 133 by the elastic force of the spring 136, the support arm 118 moves upward while the seedling raising box support body 119 is in the retracted state. Next, when the seedling box support 119 of the support arm 118 passes the rib on the side surface of the lowermost seedling raising box A or comes to a desired predetermined position next to the second seedling raising box A from the bottom, The upper end of the timer longitudinal axis 134 is disengaged from the engagement hole 133, and the support arm 118 is
(With other factors such as the weight of the support arm 118), the seedling box support 119 is engaged with the second seedling box A from the bottom, and the lower seedling box A is removed as it is. To lift the seedling raising box A.

The seedling raising box A in the lowermost stage is placed on the placing / moving frame 70. In this state, the placing / moving frame 70 is located on the left side. The placement / movement frame 70 is moved to the right, and the placement space for the seedling raising box A1 on the right side of the placement / movement frame 70 becomes the seedling box supply device 48.
Is located below, the frame moving motor 75 is stopped,
Next, the supply motor 127 is energized to supply only one seedling box A by the seedling box supply device 48 as described above (FIG. 16B). Again, when the frame moving motor 75 is rotated forward to move the placing and moving frame 70 by one box toward the right side (FIG. 16C), the placing space for one box of the placing and moving frame 70 becomes a nursery box. Since it is located below the supply device 48, the frame moving motor 75 is stopped, and then the motor 127 is energized and the seedling box A is supplied by the seedling box supply device 48 located on the right side (FIG. 16C). (E in FIG. 16), the seedling raising box A is placed over the entire length of the placement moving frame 70 (FIG. 1).
6 f).

When the nursery box supply device 48 is first moved to the left in this state, the stopper 76 in the retracted state located on the upper surface of the innermost nursery box A is moved to the end face of the nursery box A. After passing through, the vehicle turns to an upright state and is located substantially above the right traveling rail 31 (FIG. 16G). Next, when the frame moving motor 75 is reversed to open a placement space for one seedling box A at the left end of the placement moving frame 70, this placement space is At the lower position, the frame moving motor 75 is stopped, and then the motor 127 is energized, and only one seedling box A is supplied by the seedling box supply device 48 (FIG. 16H). At this time, the left end surface of the seedling raising box A on the right side of the stopper 76 is in contact with the stopper 76. Therefore, when the placement moving frame 70 moves to the left side, only the placement moving frame 70 moves, and the other side surface The inner seedling box A comes into contact with the stopper 76 provided in the stopper 79 and becomes immobile, and the seedling box A adjacent to the seedling box A dammed by the stopper 76 contacts the whole seedling box A. As a result, it is immobilized with respect to the placement moving frame 70, and moves until one placement space for one box is opened on the left side, and one seedling raising box A on the right side falls and is placed (FIG. 16C). ). When the placing and moving frame 70 is moved to the left again by one box, the right seedling raising box A falls (FIG. 16), and the space of the left placing and moving frame 70 faces below the seedling box supply device 48. Therefore, the seedling raising box A is supplied (FIG. 16), and when this is repeated (FIG. 16), the placement moving frame 7 is provided.
The seedling box A is placed on the placement nursery 44 on the right side of the traveling rail 31 while the seedling box A is being supplied by moving 0 to the left.

Next, though not shown, when the nursery box supply device 48 is moved to the right and the placement moving frame 70 is moved to the right, the parallel operation of the nursery boxes in the first row is completed, and The next seedling box A is supplied onto the moved placement moving frame 70, and in this state, the traveling frame body 47 is moved forward, and the above operation is repeated to perform the seedling box parallel work in the second and subsequent rows. The seedling raising boxes A can be juxtaposed on the left and right sides of the center running rail 31. Therefore, when the placing / moving frame 70 moves from one of the left and right sides of the traveling rail 31 to the other side, the seedling raising box A on the placing / moving frame 70 is lowered to one side (except for the first row). Since the seedling box A is newly supplied on the placement moving frame 70, the work efficiency is improved. That is, only in the first row of the initial operation, the seedling box A is supplied on the placement moving frame 70. It is necessary to move the placement moving frame 70, but when the second row, the seedling raising box A is already supplied on the placement moving frame 70, and the work efficiency is greatly improved. Also, since the movement of the placement moving frame 70 is configured to intermittently move by one box, the placement of the placement movement frame 70 to the placement nursery 44 and the movement of the placement movement frame 70 Can be smoothly and reliably supplied at the same time.
That is, when the seedling raising box A is supplied from the seedling raising box supply device 48 to the placement moving frame 70, the placement moving frame 70 is stopped, so that the seedling raising box A is prevented from shifting with respect to the mounting moving frame 70. And it can be placed on the floor smoothly.

Thus, the seedling box supply device 48 is provided movably in the left-right direction with respect to the traveling frame 47, and is the difference from the width of the seedling box supply device 48 that is larger than the width of the traveling rail 31. When the seedling box supply device 48 is moved left and right, the left and right stoppers 76 provided on the seedling box supply device 48 are substantially above the left and right running rails 31. And the innermost nursery box A on the placement moving frame 70 can be placed near the traveling rail 31. The nursery box supply device 4
Since the rotation control of the motor 127 may be changed for the vertical stroke of the seedling box support 119 of FIG. 8, the step stacking seedling box A supplied by the supply cart 49 is moved to the low placement moving frame 70 near the floor. Also surely supply. Further, the placing and moving frame 70 is provided at a predetermined height so as not to contact the root cutting net or sheet.
The shock absorbing rotation members 84 are provided on both left and right sides of the moving body 70, so that the shock when the moving member 70 is lowered from the mounting moving frame 70 to the mounting surface is reduced, and the scattering of soil and seeds is prevented.
