〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic plan view of the entire grafting device, where 1 is a seedling supply section, 2 is a scion processing section, 3 is a rootstock processing section, 4 is a seedling joint section, and 5 is a seedling gripping body (clip) supply. 6 indicates a seedling adhesion/discharge section, and 7 indicates a grafted seedling transport section.

The seedling supply section I supports a pair of scion seedling cassette 8 and rootstock seedling cassette 9 so as to rotate in the direction of the arrow at a predetermined interval. The cassettes 8 and 9 have the same substantial configuration, so one (cassette 8 for scion seedlings) will be explained, and the other (cassette 9 for rootstock seedlings) will be explained with the same reference numerals attached to common parts. Omitted. The scion seedling cassette 8 is
A large number (20 in the drawing) of seedling support arms II, 11... are arranged at predetermined intervals around the outer periphery of the disc part IO, and a seedling support hole 12 is provided at the tip of each seedling support arm 11. ing. The scion seedling A1 rootstock seedling is supported in each seedling support hole 12, 12, . . . . Although not shown below the seedling support arms 11, 11..., a seedling A or B supported by the seedling support hole 12 is placed.
When rotating due to the rotation of the disk part IO, an L-shaped anti-sway body is provided to prevent the seedlings from shaking due to the inertia and falling from the seedling support hole 12 and from making mistakes in transferring the seedlings. Also,
The scion seedling cassette 8 is configured to be attachable to and detachable from the rotating shaft 13 via a fitting portion 14 .

And cassette 8 for scion seedlings (cassette 9 for rootstock seedlings)
A plurality of sets are prepared, and the scion seedling A or rootstock seedling B is manually suspended and supported in each seedling support hole 12 so that the vicinity of the base of the petiole of the cotyledon is supported, and the cassette is replaced. ing.

In addition, as shown in FIG. 1, the supporting direction of the seedling with respect to the seedling support hole 12 is such that in the scion seedling A, the cotyledon development direction is oriented in the rotation tangent direction, and in the rootstock seedling B, the cotyledon development direction is oriented in the rotation center direction. If the grafted seedlings are supported in such a way that the cut surfaces of the scion and rootstock are facing each other and are glued together, the cotyledon development direction of the scion and the cotyledon development direction of the rootstock will be crossed, and subsequent grafting will be difficult. Although this was predicted to have a positive effect on the growth of seedlings, it is also possible to create grafted seedlings even if the direction of the cotyledons is changed, so there is no need to be particular about the direction in which the cotyledons develop.

The rotating shaft 13 is intermittently rotated (or synchronously rotated) by a stepping motor (not shown), and the intervals of the intermittent rotation are synchronously set to match the mutual spacing between the seedling support arms 11 and 11. .

The stepping motor driver is one that can arbitrarily adjust the rotation angle and rotation speed. A programmable controller is used in the control unit that controls each of these operations to perform sequence control, and a timing chart thereof is shown in FIG. There are three control modes: ``Manual mode J'' that allows each part to be driven independently, ``1 plant grafting mode'' that grafts only one plant and stops, and ``20 plant grafting mode'' that grafts 20 plants continuously.
It has a mode. It is also equipped with an emergency switch that stops all mechanisms in the event of an abnormality.

Next, the operation of the grafting device configured as described above will be explained.

First, prepare the seedlings and clips. For the seedlings, place the scion seedling A in the scion seedling cassette 8 so that the cotyledon development direction is tangential, and the rootstock seedling B in the rootstock seedling cassette 9. The cotyledon developing parts are suspended in the seedling support hole 12 so that the developing direction faces the radial direction, and the fitting parts 14 are set on the rotating shaft 13, respectively. The clip 48 is placed inside the clip housing case 50.
A large number of them are housed so as to overlap in the vertical direction from the upper end supply port along the guide 50b, and a lid 50e having a presser plate 50c and a spring 50d is placed over them. The lower part of the cassette-shaped clip storage case 50 that accommodates a large number of clips 48 is inserted into the case fitting hole 49a provided on the outer periphery of the rotating disk 49, and the engaging flange 4 of the rotating disk 49 is inserted.
The rotating disk 49 is loaded by rotating so that the engaging protrusion 50a of the clip housing case 50 is engaged with the clip housing case 9b. Then, select the control mode of the control section and turn on the power switch.

When the power switch is turned on, a stepping motor (not shown) for driving the rotating shaft 13, a stepping motor 20 for transporting seedlings (driving the rotating shaft 17), a bin cylinder 28 for grasping and releasing seedlings, etc. Air cylinder 39 for operating the scion hypocotyl support 40. Stepping motor for feeding clips 49. Stepping motor for cutting seedlings 34.
42. Air cylinder 54 for clip hook. The air cylinders for discharging seedlings operate according to the timing chart shown in FIG. 6. That is, first, the scion processing section 2 and the rootstock processing section 8
The seedling transport rotary disk 18.18 starts rotating in the direction of the arrow,
Next, after 0.15 seconds, the disk 10.10 of the seedling supply unit l rotates in the direction of the arrow, and after 0.25 seconds from the start of rotation of the seedling conveyance rotary disk 18, the bin cylinder 28 extends and the cam 27 is extended. , the movable hand 22 is moved via the cam roller 29 to open a space between it and the fixed hand 21, and the seedling A is suspended in the seedling support hole 12 of the seedling support arm 11;
With the hypocotyl of H positioned in the opening, insert bottle cylinder 2.
8 and fix the fixed hand 21. It is held between the urethane rubber 30 and 30 of the movable hand 22.

The seedlings A and B held by the hands 21 and 22 are conveyed by the rotation of the seedling conveying rotary disk I8 to a position facing the scion cutting device 329 and the rootstock cutting device 3S, and then stopped. Then, the rotation arm 35.43 is rotated by the rotation of the stepping motor 34.42, and the cutting blade 37.45 cuts off the scion seedling A with the root side facing diagonally downward, and the rootstock seedling B has cotyledons. One side and the growing point are cut with the cut surface facing diagonally upward.

When the scion seedling A is cut, a hypocotyl presser 38 is provided on the front side in the rotation direction of the cutting blade 37, and a hypocotyl supporter 40 that is moved by an air cylinder 39 is provided on the fixed disk I5 side. Therefore, when cutting the hypocotyl, it can be stably cut at a predetermined position, and even if the hypocotyl is curved, it can be cut at a fixed position. That is, if there is no hypocotyl presser 38 or hypocotyl support 40, as shown in FIG.
If the shaft is straight a, it will be cut at point P, but if the shaft is straight b
If the cutting point is bent like +c, the cutting point will be shifted to the position, or the cutting will not be possible, or the cutting point will be shifted downward, but the present invention can avoid such situations.

In addition, for rootstock seedling B, as shown in Figure 12 (a), shallow cutting by cutting only one cotyledon leaving a growing point, deep cutting as shown in (c), and neck cutting as shown in (d) are all possible. It is preferable to cut one side of the cotyledons and the growing point as shown in (B). Therefore, in the present invention, a cotyledon presser body 46° and a cotyledon presser body 46° on the front side in the rotational direction of the cutting blade 45 and a seedling conveying rotary disk 18 are provided. Since the cotyledon posture regulating body 47 is provided on the upper side, when cutting the rootstock seedling B, the cotyledons to be left can be tilted by θ degrees and cut into a desired state as shown in FIG.

The scion seedlings A and rootstock seedlings B thus cut are positioned one above the other at the seedling junction 4, with their respective cut surfaces facing each other as shown in FIGS. 11(a) to 11(c). It turns out. In this example, the so-called single-leaf cutting grafting method is mechanized. For example, in the case of the split grafting shown in FIG. If the cotyledon hangs down on both sides, clipping cannot be done when mechanizing it, so mechanization is possible by providing a cotyledon posture regulating body as shown in (Iff).
In the call grafting shown in Figure 19, as shown in (a), the hypocotyls of scion seedling A and rootstock seedling B are broken and clipping cannot be done, but as shown in (rl), scion seedling A and rootstock seedling Mechanization is possible by controlling the posture of each seedling B using a cotyledon posture regulating body.

In the seedling gripping body (clip) supply section 5, the seedling conveying rotary disk 1
0.5 seconds after the start of rotation of stepper motor 51
The rotating disk 49 rotates and stops when the clip storage case 50 is at the clip supply position. When this rotary disk 49 rotates and reaches the clip supply position, the stopper release mold 50i comes into contact with the stopper 50f, the stopper 50f rotates horizontally around the bin 50g, and the clip 48 in the case is ejected. This allows them to be taken out horizontally one by one from the outlet at the bottom of the case. The clip 48 inside the clip storage case 50
are sequentially supplied to the slide guide 57 of the seedling adhesion/discharge section 6.

In the seedling adhesion/discharge section 6, the piston 5 of the air cylinder 54
5 extends 0.5 seconds after the graft conveying rotary disk 18 starts rotating, and moves the piston rod 56.

As the piston rod 56 moves, the clip 48 is pushed out by the clip pushing part 59, the slide block 57 is moved forward by the coil spring 65, and when the slide block 57 stops moving by the stopper, the clip 48 opens along the slide block 57. At the same time, the cam 60 (beak 61.610 roller 63.63
are moved away from each other against the force of the return spring 64. As a result, the tips of the beaks 61 and 61 are brought closer together, and the cut surfaces of the scion seedling A and the rootstock seedling B are shown in Figure 22 (A).

They are brought close together as shown in (b) and held by clips 48 to adhere the cut surfaces. When the clip 48 inside the clip storage case 50 is removed, it is inserted into the clip sensor 5.
0j is detected, the stepping motor 5I is intermittently rotated to rotate the rotary disk 49, and stopped when the clip storage case 50 reaches the clip supply position, and the clip supply operation is restarted.

Once the grafted seedling has been clipped, the hands 21 and 22 are opened (at the same time, the air cylinder for seedling discharge extends to push out the grafted seedling, discharge it, and let it fall. At the position where the grafted seedling falls, there is a grafted seedling conveying section 7). A belt conveyor is provided, by which the materials are transported and stored in containers.

Among these series of operations, the operations of grasping the seedling, cutting it, supplying the clip, and gluing the seedling are performed almost simultaneously when the rotation of the seedling conveying rotary disk I8 is stopped.

〔Effect of the invention〕

As explained above, according to the grafting clip supply method of the present invention, the following effects can be achieved.

(2) Since the clips are housed in a cylindrical case provided with a guide that restricts the movement of the clips, a large number of clips can be housed in the case not only by manual force but also by mechanical force.

Further, the clips can be continuously taken out and supplied one by one from the storage case.

■ The cylindrical case that houses the clips has a clip supply port on one side and a clip outlet with a stopper on the other, and the stopper is released during work to feed the clips, making mechanized work easier. Moreover, it is possible to carry out grafting work reliably and efficiently.

■ Multiple cylindrical cases for storing clips are arranged in a circular or linear manner to supply clips, which increases the number of clips that can be stored (and thus increases the continuous working time due to mechanization). , efficient grafting work can be done.
