By opening this guide rod 40, the seedling box B supplied from the seedling box supply frame 1 side can be taken out.

Switch-type seedling box sensors S1 and S2 for detecting the presence or absence of the seedling box B are arranged in front of and behind the drive roll 2, and similarly before and after the seedling box stopper 30 in the seedling box feeding passage 7. Seedling box sensors S3 and S4 are provided. By using these seedling box sensors S1 to S4 and the controller, the seedling box B can be supplied from the seedling box supply frame 1 to the seedling box feeding passage 7. Further, the seedling box supply from the upper and lower seedling box supply frames 1 is performed before the seedling box supply frame 1 on the upper stage side, and the supply from the lower stage side follows. Seedling box sensors S1, S3 are seedling box B
When the presence of the seedling box B is detected, the motor M1 is stopped, and when the absence of the seedling box B is detected, the motor M1 is driven. Also, seedling box sensor S
2, S4 stops the motor M1 when detecting the presence of the seedling box B, but drives the motor M1 when detecting the absence of the seedling box B.

By detecting the seedling box sensors S1 to S4 as described above, the seedling pushing rod 9 position in the seedling box feeding passage 7, the seedling box stopper 7 and the driving roll 2 of the upper seedling box supply frame 1 part.
The seedling boxes B can be continuously and continuously supplied to and fed out of the respective positions such as the position between and, and the position above the drive roll 2.
As described above, by driving the driving roll 2 and the feeding roll 25, the seedling box B on the seedling box feeding frame 1 can be supplied to the seedling box feeding passage 7 side.

When supply by the drive roll 2 or the like is not performed due to a failure of any one of the seedling box sensors S1 to S4 or other mechanical parts, clogging of the seedling box B, or the like, the pressing roll 3 is moved to the opposite arrow L direction.
By switching to the direction and separating from the upper surface of the box edge C,
The box edge C of the seedling box B is separated from the drive roll 2 by a gap D, and the seedling box B is easily moved in the front-rear direction.

Therefore, the seedling box B is used as it is for the seedling box feeding passage 7
When shedding to the side, the nursery box B may be pushed by hand. At this time, even if the bottom part of the seedling box B is engaged with the feeding roll 25, it is adapted to be interlocked with the belt 26 via the ratchet, so that the seedling box B is lightly rotated while rotating the feeding roll 25.
Can be drained. Moreover, when pulling out the seedling box B upward, the bottom part may be floated from the feeding roll 25.

Now, assuming that the seedling box sensors before and after the lower drive roll 2 are S5 and S6, and the motor is M2, the seedling box supply control unit 3 that is the drive control of these motors M1 and M2.
9, and this operation is as shown in FIGS. 2, 9 and 10.
Here, S7 is a seedling box sensor for detecting the presence or absence of an empty seedling box B at the end of the seedling box feeding passage 7. Seedling box sensor S
When LPS 1, S2, S5 and S6 are turned off when the seedling box B is not detected, the lamp LP is turned on. Even if this lamp LP is turned on, the seedling box B is not replenished, and when the seedling box sensor S7 is ON and the seedling box sensor S4 is OFF for a certain period of time, the buzzer BZ notifies of the seedling shortage.

If S3 is not turned on even if the motor M1 is driven while the seedling box sensor S1 is turned on, the seedling box B will not be sent out due to being jammed in the middle. In such a case, after the motor M1 is driven for a fixed set time (for example, about 4 seconds), the driving of the motor M1 is automatically stopped, the motor M2 is turned on, and at the same time, the lamp LP or the buzzer BZ is turned on.
Give an alarm. That is, the seedling box supply from the upper stage seedling box supply frame 1 is prioritized over the supply from the lower stage.

11 to 13, the difference from the above example is that a guide sensor S8 for detecting the opening and closing of the guide rod 40 is provided, and this guide sensor S8 detects the closed position of the guide rod 40 and turns it ON. When in the guidance state, the motor M
1 or M2 is driven, but the motor M1 is turned off when the guide rod 40 is in the opened state. Than this,
When the lower seedling box B is removed, the seedling box B is supplied from above by the detection of the seedling box sensor, so that the succeeding seedling box collides with the seedling box to be removed and the seedling box is removed. It is possible to prevent troubles such as the difficulty and the fact that the fuses are easily blown when the motors M1 and M2 are forcibly stopped and the failure is likely to occur.

In FIG. 11, the pivot shaft 41 of the guide rod 40 is provided on the seedling box feeding passage 7 side, and in FIG. 12, it is provided on the seedling box supply frame 1 side.
