Next, the lower clamp device 27 will be described.

As shown in FIG. 11, the lower clamp device 27 is for holding the lower part of the hypocotyl of the scion seedling to be cut, and the chuck claws 90, which oppose each other in a state of being guided so as to move forward and backward. Has 91. The rear portions of these chuck claws 90, 91 are connected to wires 92, 93, and are also connected to the cams in the cam group 70 via rollers 94, 95. Therefore, the opening and closing of the chuck claws 90 and 91 is controlled in accordance with the operation of this cam.

Next, the spike cutter 28 will be described.

As shown in FIG. 2, this scion cutter 28 can be moved forward and backward by an air cylinder 29, and its forward movement cuts the hypocotyls of the lower part of the cotyledon of the scion seedling. The cutting position at this time is approximately 10 mm below the cotyledon position of the scion seedling by adjusting the height of the lifting plate 30 of the scion transport conveyor 6, and the cutting surface is the hypocotyl of the scion seedling. It is arranged so as to be cut obliquely at an angle of about 30 degrees (see FIG. 26). This is because when they are joined to the rootstock, the joining area is increased to increase the survival rate. (2) Conveying means 22 As shown in FIG. 16, the conveying means 22 nips and conveys the scion cut by the scion cutter 28 to the root position cut by the scribing cutter 28 'described later. It has a rotation base 101 that rotates about the rotation shaft 100. A slide base 102 is placed on the upper part of the rotating base 101, and the slide base 102 is connected to a cam in the cam group 70 via a pulley 111 and a wire 106, and moves in the horizontal direction by the rotation of the cam. It is controlled. An upper clamper 103 is attached to the slide base 102 via a clamp base 113, and a true leaf spread preventing bar 104 is attached above the upper clamper 103. Then, the upper clamper 103 is

It is possible to rotate up and down around. Further, two air cylinders 108 and 109 are axially attached to the upper portion of the slide base 102, and the other end of the air cylinder 109 is attached to the clamp base 11 via a bracket 115.
It is attached to 3.

The rotary base 101 is provided with a roller 114 for contacting the clamp base 113 for correcting the locus. This roller 114 is the upper clamper 1
It is used to correct the motion locus of 03 to smoothly insert the scion into the clip.

As shown in FIG. 17, a rotary solenoid 105 is attached to the rear of the upper clamper 103, and the rotary solenoid 105 controls the opening and closing of the grip portion at the tip. Also, the true leaf spread prevention bar 10
An air chuck 107 is attached to the rear portion of the sheet No. 4, and the grip portion of the true leaf spreading prevention bar 104 is controlled to be opened and closed by the air chuck 107.

Next, the operation of the carrying means 22 will be described with reference to FIGS. 31 and 32.

The upper clamper 103 and the true leaf spread preventing bar 104 can be moved forward and backward by the movement of the slide base 102, and are advanced when cutting the scion seedlings to spread the true leaf spread preventing bar 104. After the leaf is prevented from spreading and the hypocotyl is grasped by the grasping portion of the upper clamper 103 and the ear portion is cut, the rotation base 101 is rotated to move above the rootstock position while grasping this ear portion. . On the rootstock side, the one air cylinder 108 is connected to the upper clamper 1.
By rotating 03 about the vertical rotation fulcrum 112, the spikes for spikes are inserted into the clip 130.
Further, the other air cylinder 109 further pushes the spikes with a predetermined pressure in order to improve the survival rate of the graft.

FIG. 33 shows the locus of insertion of the spikes into the clip 130 by the upper clamper 103.
In the present embodiment, when the spikes are inserted by the rotation of the upper clamper 103, the slide base 102 comes into contact with the trajectory correction roller 114 provided on one end side of the rotation base 101, so that the slide base 102 moves. The forward movement is blocked, and the clamp base 113 rotates about the vertical rotation fulcrum 112. Therefore, the tip of the bristle portion is smoothly inserted into the clip 130 with a locus that is approximately a straight line, as compared with the case shown in FIG. 34 in which the locus is not corrected. (3) Cutting means 23 As shown in FIG. 2, the cutting means 23 on the rootstock side has a front seedling scraping device 25 'for scraping one rootstock seedling before the rootstock seed to be cut. , A cutting seedling scraping device 26 'for scraping a rootstock seedling to be cut, and a lower clamp device 27'
, Rootstock cutter 28 ', and tip clamp device 120
And a seedling gathering device 121.

However, except for the tip clamping device 120 and the seedling gathering device 121, the construction is the same as that of the cutting-side cutting means 21 described above, and therefore the description thereof will be omitted.

The tip clamping device 120 is for grasping and ejecting the tips of the rootstock cut by the rootstock cutter 28 ', and the tip clamping unit 1 as a gripping portion at the tip.
22 and an air chuck 123 at the rear portion thereof, and the tip clamp portion 122 is provided by the air chuck 123.
Is controlled to open and close. Further, two air cylinders 124, 1 integrally fixed to the rear portion of the air chuck 123 are provided.
27, and the tip clamp portion 122 can be moved forward and backward by the air cylinder 124. Then, when cutting the seedlings for the rootstock, the lower clamp device 2
7'advance to clamp the hypocotyl under the cotyledon of the rootstock, and the tip clamp part 122 moves forward to grip the tip of the rootstock and cut the tip with the rootstock cutter 28 '.
In the operation of the tip clamp part 122 at this time, first, one air cylinder 127 extends and moves to the standby position, and in this state, the other air cylinder 124 extends and moves to the cutting position.

The cutting position of the rootstock seedlings by the rootstock cutter 28 'is determined by the lifting plate 3 of the rootstock conveyor 7.
By adjusting the height of 0 ', it is about 5 mm below the cotyledon position of the rootstock seedling, and its cutting surface is cut obliquely at an angle of about 30 degrees with respect to the hypocotyl of the rootstock seedling. (See FIG. 27). This is to increase the contact area with the scion seedling at the time of grafting to increase the survival rate.

After cutting the tips as described above, the tip clamps 122 retract due to the air cylinders 124 and 127 contracting substantially at the same time, and the cut tips are moved from the grafting position to the discharging position and discharged. In addition, when discharging the cut tip, the tip clamp part 122 is unclamped (restrained).
In many cases, even if it is released, it does not easily fall, and it is necessary to bring it outside the device, but if the stroke is lengthened, the air cylinder will protrude outward and it will take a long time. Therefore, in this embodiment, 2
By integrally connecting the two air cylinders 124 and 127, the processing can be performed in a short time. This makes it possible to reliably discharge the tips, and does not hinder the subsequent seedling treatment work.
