Field of the Invention The present invention relates to an improvement of a grafted seedling producing machine for automatically feeding and adhering rootstock seedlings and scion seedlings to produce grafted seedlings. Is. 2. Description of the Related Art As a conventional grafted seedling producing machine, a seedling placing table on which a rootstock seedling and a scion seedling are placed, and each seedling placed on each seedling placing stand are individually gripped. A transport device for transporting, a cutting device that intervenes in the transport route of each transport device and cuts the cotyledon part of the rootstock seedling and the hypocotyl part of the scion seedling to be transported, and is gripped by both transport devices. There is proposed a seedling adhering device in which both cut surfaces of the rootstock and the scion are opposed at a predetermined position and adhered and fixed by a clip (for example, Japanese Patent Laid-Open No. 2-107125). In this conventional grafted seedling manufacturing machine, there is still room for improvement regarding the supply and bonding of clips by the seedling bonding device. Therefore, the present inventor prototypes a seedling adhering device 151 as shown in FIG. In this device, the clips 62, 62 are attached to the air cylinder 1.
At 55, the guide 62 is guided toward the grafting position A, and the clip 62 is held in the open state at the tip of the guide groove 152, while the rootstock seedling 3 is transferred by the transfer arm 153 and the scion seedling 4 is transferred by the transfer arm 1.
At 54, they are respectively conveyed to the grafting position A, and both cutting ends 103, 104 of these rootstock seedlings 3 and scion seedlings 4 are supplied between the sandwiching portions of the opened clip 62. By closing the clip 62,
Both seedlings 3 and 4 are adhered. In this prototype, the clip 64 is attached at the grafting position A.
There is an advantage that it can be continuously supplied and adhered from the rear side by the guide path 152 and the mechanism is simple. However, due to the bending and inclination of the seedlings, the cutting edges 103, 1 of the seedlings
04 is in a position away from the clip 62,
When the cutting ends 103 and 104 of both seedlings are located apart from each other, the clips 62 may not be bonded even if they are closed as they are, or both seedlings 3 and 4 may not be able to survive well even if they are bonded. However, there was a problem that expensive grafted seedlings were likely to be wasted. The present invention has been made to solve this problem, and provides a grafting seedling manufacturing machine capable of reliably carrying out the grafted seedling manufacturing process by preventing adhesion failure due to bending and inclination of the seedlings. The purpose is to provide. [0006] In order to achieve the above object,

At this time, as shown in FIG. 13, the auxiliary cutting blade 101 presses the cotyledon 97 on the remaining side on the cotyledon support roller 98 by its side surface, so that the rootstock seedling 3 does not escape from the cutting blade 46. It is possible to prevent the cutting position from shifting. When the cotyledon 102 is incompletely cut and the veins 109 remain uncut, the veins 109 are cut by the tip of the auxiliary cutting blade 101. Further, even when the cotyledon 97 on the remaining side is torn, a part of the torn cotyledon 97 is cut by the tip portion of the auxiliary cutting blade 101, and the tear does not expand. Thus, in the second embodiment, the cotyledon 102
Can be reliably separated from the rootstock seedling 3, and thus the adhesion of the spikelet seedling can be further ensured. Moreover, in this embodiment, since the cotyledon 97 on the remaining side is pressed by the side surface of the auxiliary cutting blade 101, there is no possibility that the tip of the auxiliary cutting blade 101 damages the cotyledon 97.

Since it is close to the normal direction of 8, the cotyledon 102 on the cutting side can be reliably cut without damaging the cotyledon 97 on the remaining side. As described in detail above, according to the present invention, the cutting ends of rootstock seedlings and scion seedlings are tilted toward the bottoms of the openings of the clips by the carrier device, and are conveyed to both seedlings. The cut end was brought into contact with the bottom of the opening of the clip, and the clip was closed to bond both seedlings. Therefore, in the present invention, both cutting ends are once aligned along the bottom of the opening of the clip, and the clip is closed and adhered from that state, so if the seedling is bent or tilted, the cutting end of the seedling should be kept away from the clip. Even if the seedlings are in different positions or the cut ends of both seedlings are distant from each other, the individual difference of such seedlings can be tolerated and reliable adhesion can be achieved, and the adhesion can always be performed in a good posture, thus improving the survival rate. There is an effect that can be.
