Attached to the storage cart side end of 3b, 93b,
It consists of an extrusion member 93c whose length is slightly longer than the width in the insertion/removal direction of the storage trolley 45, and when the air cylinder is operated to advance the rod, the extrusion member 93c at the tip pushes out the shelf T of the storage trolley 45 for germination. The seedling box S is transferred to the shelf T of the storage cart 55 for greening. A reed switch is used in the air cylinder 93a to detect that the rod has advanced a predetermined length and the seedling box S has been stored in the shelf T of the greening storage cart 55 from the germination storage cart 45. A seedling box storage sensor 97a is provided.

Moreover, on the movement trajectory of the guide pole 94a,

Further, sensors 97e and 97f for detecting fixed positions are arranged on the terminal end sides of the chain conveyors 91 and 92.

Further, an optical sensor 97t including a light emitting element 971 and a light receiving element 972 is installed on the side of the storage cart 45 side of the lifting platform 94, and the optical sensor 97t forms an angle that forms a shelf of the storage cart 45. is detected, and the lifting platform 94 is controlled to stop based on the detection result. As shown in FIG. 5, the optical sensor 97t has a light emitting element 971 and a light receiving element 972 arranged side by side in a sensor main body 970 provided at the illustrated position, and the light emitting element and the light receiving element are controlled by a separately installed control circuit. 973, the light emitting element emits light, and the light reflected at the angle is received by the light receiving element to operate. Note that a light emitting element and a light receiving element are provided near the control circuit, an optical fiber is extended from the light emitting element and the light receiving element, and the tip of the optical fiber is housed in the sensor main body attached to the lifting section 94. It is also possible to use one in which light is emitted from the tip and the reflected light is captured by the tip of the other optical fiber and transmitted to the light receiving element. When the optical sensor 97t detects the angle, a counter 9730 in the control circuit calculates this as a coefficient, and when the coefficient value of the counter 9730 reaches a preset value, the hydraulic cylinder 94c for driving the 94th elevation is activated.
The drive control circuit is configured so that the motor is stopped. The detection target of the optical sensor 97t is the angle,
In other words, it is not limited to a shelf, but may be the seedling box S itself.

Furthermore, guide chutes 99 are provided at fixed shelf intervals between the opposing positions of the storage trolley 45 for germination and the storage trolley 55 for greening, and are arranged in three rows for each shelf row. This guide chute 99 is positioned slightly lower than the shelf T of the storage trolley 45 for germination and slightly higher than the shelf T of the storage trolley 55 for greening in order to facilitate the transfer of the seedling box S. There is.

In addition, the storage cart 55 for greening is placed in the fixed position of the chain conveyor 92.
It is lifted to a predetermined height position by a lifting device 60 shown in FIG. 6 installed in the conveyance direction of FIG.

The lifting device 60 is installed parallel to the extending direction of the chain conveyor 92, and as shown in FIG. Support, L-shaped rod 6
At one end of 2a, 62b, the storage cart 5 for greening is installed.
Lifting rollers 63, 63b that come into contact with the lower surface of 5
The two L-shaped rods 62 are attached to the other end.
A connecting rod 64 that connects a and 62b is attached, and a cylinder 65 is provided at one end of the connecting rod 64. When the cylinder 65 is actuated, the L-shaped rods 62a and 62b rotate clockwise in the figure, lift up using the grounding wheels 61a and 61b as fulcrums, and move the greening storage cart 55 to the second position. 4. Lift up one shelf as shown in Figure 4.

As a result, the height between the shelf T on which the seedling box S transferred from the storage cart 45 for germination to the storage cart 55 for greening exists and the shelf T of the seedling box S that was left in the storage cart 45 for germination is become equal. This is because the position of the nozzle that automatically sprays water to the seedling boxes S during greening is fixed, so the seedling boxes S of each storage trolley 45, 55 are fixed.
This is because it is necessary to make the shelves T in which the items are stored be the same.

Next, the operation will be explained.

Storage cart 45 loaded with germinated seedling boxes S
and the empty green storage cart 55 are guided by the guide 98a.
and 98b to chain conveyors 91 and 92
When placed on the storage carts 45 and 5, the motor for driving the chain conveyor is rotated, and the two rows of storage carts 45 and 5
5 is moved, and when it reaches the home position, the home position detection sensors 97e and 97f detect this, the motor is stopped, and each storage trolley 45 and 55 is moved.
is fixed in place. In this state, the lifting device 6
0, the greening storage cart 55 is lifted to a position one step higher than the shelf.

A guide pole 94a having an extrusion device 93 on a lifting platform 94 is moved by the motor drive of a pinion 95a, and a limit switch 97b for detecting the shelf width movement direction is moved to a position corresponding to the side of the shelf diode T in the front row of the storage cart 45. detected and fixed. At this time, the extrusion device 93 on the lifting platform 94 is located at the second stage from the bottom of the storage cart 45.

In this state, the air cylinder 93a in the extrusion device 93 is operated to advance the rod together with the extrusion member 93c, and the seedling growing box S of the storage cart 45 for germination is moved from the storage cart 45 for germination to the guide chute 99. After that, it is pushed out and stored on the lowermost shelf T of the shelf row of the storage cart 55 for greening. When the seedling box storage sensor 97a detects that the air cylinder 93a has advanced a predetermined amount and the seedling box S has been stored on the lowermost shelf T of the storage cart 55 for greening.
The air cylinder 93a is operated to move the rod back and forth, and when this movement is completed, the lifting platform 94
is raised.

The optical sensor 97t detects the angle of the shelf T as it rises, and counts up the counter. Then, according to the information preset in the control circuit 973, the hydraulic cylinder 94c for driving the lifting platform 94 is stopped every time the coefficient becomes an even number, and the extrusion device 93 comes to face the shelf T at every other stage.

In this way, the extrusion device 93 is then made to face the fourth shelf T from the lowest side of the germination storage cart 45 placed on the chain conveyor 91. When this state is reached, the extrusion member 93c at the tip of the rod of the cylinder 93a of the extrusion device 93 pushes out the next seedling raising box S from the shelf of the germination storage cart 45 to the shelf T of the greening storage cart 55, and pushes it out onto the shelf. It is stored in the stage T, and the cylinder 93a is retracted and the lifting platform 9
4 by two shelves.

By repeating such an operation, when all the seedling boxes S are stored in every two rows T of the shelf rows of the greening storage cart 55 from the germination storage cart 45,
A guide pole 94a supporting the lifting platform 94 is moved forward by the motor drive of a pinion 95a, and a limit switch 97c for detecting the shelf width movement direction is moved.
When it is detected that the storage cart 45 has reached the second shelf row position, it is fixed at that position.

In this state, the extrusion device 93 moves the seedling boxes S to the shelf T of the greening storage cart 55 one after another, starting from the top shelf of the storage cart 45 for germination.
will be transferred. When the seedling boxes in the central row of shelves have been transferred, the guide pole 94a is moved forward, and the limit switch 97d for detecting the shelf width movement direction on the terminal side is activated to move the seedling boxes to the third row (the last row) of the storage cart 45. When it is detected that you have reached the shelf row position of
It will be fixed in that position.

This time, since the extrusion device 93 is in the lower position,
Starting from the second shelf T from the bottom of the germination storage cart 45, the seedling raising boxes S are sequentially stored in two shelves T of the greening storage cart 55 by the extrusion device 93.

As described above, each of the storage carts 45 and 55 in which the seedling raising boxes S are stored on each predetermined shelf stage can be left as is or moved to an appropriate location.
The seedlings inside are greened and grown.

In addition to the pinion and rack described above, a chain conveyor, a moving screw, etc. can be used as a means for moving the guide pole 94a that supports the extrusion device 93 on the lifting table 94. Further, the driving source for raising and lowering the lifting platform 94 is not limited to a hydraulic cylinder, but a motor can also be used.

In addition, two empty storage carts 55 for greening are prepared, and the seedling boxes S are first transferred to the first storage cart 55 for every two shelves, and after this transfer is completed, the seedling boxes S are transferred to the first storage cart 55 for greening. Move the storage trolley 55 to another position, and
The storage trolley 55 for greening is replaced by the storage trolley 45 for germination.
, and transfer the seedling boxes S every two shelves to the second greening storage cart 55 to form two greening storage carts 55 and one germination storage cart 4.
Seedling raising boxes S are stored in every two shelves in 5 and used for greening and cultivation. In this case, the motor stop control of the lifting platform 94 is performed so as to stop the motor when the coefficient value of the counter becomes a multiple of 3 or a coefficient of 3+1 (or 2). In addition, the lifting device 60 is configured so that it can be lifted in two stages, so that the shelves T of the seedling boxes S transferred to the two greening storage carts 55 from the seedling boxes S remaining on the storage cart 45 are all equally spaced. I will make it happen.

FIG. 7 shows another embodiment of the extrusion device 93, and this embodiment has a height that faces slightly inside the vertical frame member 450 of the storage cart 45 in the correct transfer position and does not face the shelf T made of an angle. Optical sensors 97t' and 97t' similar to the aforementioned optical sensor 97t are attached so as to be as follows.

The movement of the extrusion device 93 in the shelf row direction is stopped by limit switches 97b, 97c, 97d, etc., but if the stop position control by these is unknown, the light may be interrupted due to a poor relative position between the extrusion device 93 and the storage cart 45. Either one of the sensors 97t', 97t' detects the shelf frame members 450, 450. This detection signal is used to control the re-driving of the pinion 95a,
The extrusion device can be moved to the correct position and stopped.

Further, the guide chute 99 is attached to the side of the germination storage cart 45 with its both side lines rotating around the vertical axis, so that the seedling raising box S
The optical sensors 97t' and 97
It is also possible to configure the adjustment based on the output signal of t', and thereby, even when the stop position control of the extrusion device 93 is malfunctioning as described above, the seedling growing box extruded from the storage cart 45 can be adjusted. S can be reliably guided to the guide chute 99 and transferred to the storage cart 55.

〔effect〕

In the case of the device of the present invention as described above, the seedling growing boxes can be automatically transferred, thereby reducing labor and transfer space. In addition, since the extrusion device 93 is equipped with a sensor that detects a shelf or a seedling raising box, the storage cart 4
Even if the work precision of the shelf No. 5 is poor, the seedling growing box can be reliably pushed out, sent to the guide chute 99, and transferred to the storage cart 55. Further, the present invention has excellent effects such as being able to stop the extrusion device at any position detected by the sensor. Note that this sensor is not limited to an optical sensor, and may be other sensors such as a metal sensor or an ultrasonic sensor.
