2. Description of the Related Art A conventional grafting device is disclosed, for example, in Japanese Patent Laid-Open No. 6-
There is one described in Japanese Patent No. 38630. This grafting device is for a rootstock tray conveyor that is a stockstock means and a rootstock tray conveyor that is a stockstock means, and for rootstocks that are the rootstock transport means for rootstock shells and spikestocks from both tray conveyors. Root supply means for replacing each separately on the shell conveyor and the scoop shell conveyor serving as the scoop conveying means, or the shell taking-out arm device serving as the scoop supplying means, and the stand taken out on the stock shell conveyor A rootstock cutting device that clamps the lower part of the rootstock seedling of the tree shell to cut the upper part, and the upper part of the rootstock seedling of the earstock shell taken out on the scion shell conveyor is clamped to lower the bottom part. Along with cutting, a scion cutting device that grafts the cutting surface of this scion seedling to the cutting surface of the rootstock, and a clip fitting device that fits a clip to the connection part that connects the rootstock to the rootstock, The above Those with a shell removal device for taking out the graft shell planted grafted seedling fitted with the clip at the end of the wooden shell conveyor on one by one ejection tray conveyor.

The rootstock shell and the scion shell are respectively conveyed by the stock tray conveyor or the scion tray conveyor. The rootstock shell and the scion shell conveyed to a predetermined position on each tray conveyor are rotated, lifted and clamped and unclamped by the respective shell take-out arm devices to perform the rootstock shell conveyor and the scion shell conveyor. Transferred to the top.
As a result, the rootstock seedlings are conveyed by the rootstock shell conveyor, and the upper part is cut by a rootstock cutting device to form rootstocks during the feeding, and the scion seedlings are conveyed by the scion shell conveyor. During the feeding, the lower part is cut by a scion cutting device to form a scion, the scion is directly connected to the rootstock, and the clip is fitted to the grafted connecting portion by the clip fitting device. After that, at the end of the rootstock shell conveyor, the shell take-out device operates to take out the grafted shells one by one onto the discharge tray conveyor.

[0008] Further, since the stock take-out arm device is used to transfer the stock stock shell or the scion shell from the stock stock or the scion tray conveyor to the stock stock or the scoop shell conveyor, the take-out arm is set at a predetermined angle. Therefore, it is necessary to make a vertical movement by a predetermined distance as well as a vertical movement, and since the rotation angle and the ascending / descending distance must be accurately specified, the control becomes complicated.

Further, the grafted shells are sandwiched one by one and lifted up, transferred from the stock shell conveyor to a predetermined position on the discharge tray conveyor, and the grafted shells are lowered at this predetermined position and replaced one by one. Therefore, the efficiency of replacing the graft shell is very poor.

The present invention has been made in order to solve the above problems, and a row-shaped seedling pot in which a large number of pots are continuously arranged in a row in a small installation area is transferred from the supply means to the transfer means at a time.

Transferred to. At the time of this transfer, the transfer force of the auxiliary conveyor 15 acting on the row-shaped grafted seedling pots 2a is weaker than the transfer force of the rootstock transfer conveyor 12 acting on the row-shaped grafted seedling pots 2a. The grafted seedling pot 2a is not pulled by the auxiliary conveyor 15 and does not affect the transportation of the stock transport conveyor 12. In addition, the carrying force of the auxiliary conveyor is that the grafted seedling pots 2 are arranged in rows.
It works after a is almost transferred.

In this way, the grafted seedling pots 2a in a row are transferred from the rootstock conveyor 12 to the auxiliary conveyor 15.
Are transported to the end portion thereof, abut on the stopper 15c, and are temporarily stocked there. On the other hand, when the row-shaped grafted seedling pots 2a come into contact with the stopper 15c, the sensor 15d detects this and operates the seedling raising box conveyor 19 so that the empty box stock means 16 moves the seedling raising seedlings 3
To transport. When the transfer of the seedling raising box 3 is detected by the limit switch provided in the middle of the seedling raising box conveyor 19, the seedling raising box conveyor 19 temporarily stops the transfer of the seedling raising box 3, and the limit switch transfers the grafted seedlings. The means 17 is operated.

Locking claw 1 in the grafted seedling transfer means 17
7a moves along the path indicated by the double-dashed line arrow l in FIG. That is, the row-shaped grafted seedling pots 2a temporarily stocked at the end portion of the auxiliary conveyor 15 are lifted after being locked by the locking claws 17a, and along the support frame 43 in the grafted seedling stocking means 20 direction. Row-shaped grafted seedling pots 2a that have been transferred and aligned in the seedling raising box 3
Passing through above and descending to an intermediate height position at a position where it does not interfere with the already-grafted leaves. Next, the row-shaped grafted seedling pots 2 are locked by the locking claws 17a.
a is an empty box stock means 16 along the support frame 43.
It returns to the direction and is placed adjacent to the row-shaped grafted seedling pots 2a already aligned in the seedling raising box 3. The locking claws 17 after the row-shaped grafted seedling pots 2a are placed on the seedling raising box 3
7a returns to the original position in order to transfer the next row of grafted seedling pots 2a along the path indicated by the two-dot chain line arrow r in FIG. By repeating this operation, the row of grafted seedling pots 2a can be filled in the seedling raising box 3.

When the row-shaped grafted seedling pots 2a are fully filled in this way, the seedling raising box conveyor 19 operates again to convey the seedling raising box 3 to the grafted stock means 20. In the graft stock means 20, the nursery box conveyor 19
The presence of the seedling raising box 3 conveyed by is detected, the driving force transmission mechanism 51 is operated via the driving motor 52, and the attachment chain 47 is swiveled to swivel the hanger 49. As a result, the seedling raising box 3 is locked and mounted on the hanger 49, and is housed in the stock part frame 46. In this case, the hanger 49 on which the seedling raising box 3 is locked and mounted rises and stops until it contacts the projection 56 on the limit switch 53c. At the position where the protrusion 56 contacts the limit switch 53c, the next hanger 49 is stopped in a state corresponding to the height position of the nursery box conveyor 19. In this way, after the seedling raising box 3 in which the grafted seedling pot 2a is stocked is placed on each hanger 49 of the grafted stock means 20, the grafted stock means 20 is humidified and heated to cure the grafted seedlings. In this case, the graft stocking means 20 is entirely covered with a sheet such as a vinyl sheet.

As described above, according to the above embodiment, the following effects can be obtained.

Between the rootstock and the scion stocking means, the starting end portions of the rootstock conveying means and the scion conveying means are arranged in parallel to each other, and the grafting feeding means penetrates through the lower side of the end portion. Are arranged orthogonally, and since the grafted seedling stock means is continuously arranged on the downstream side of this grafted supply means,
The installation area of the whole device can be made small, and the row seedling pots 2 for rootstocks and scions, in which a large number of pots are connected in a row, are transported from the rootstock supply means and the scion supply means to the rootstock at a time It can be transferred to the means and the transport means for the scion.

Transfer of the row-shaped seedling pots 2 from the rootstock supply conveyor 7 and the earstock supply conveyor 10 to the rootstock conveyor 12 and the earstock transfer conveyor 13 is performed by the rootstock transfer means 9 and the earstock transfer means 11, respectively. Since the operation is performed by moving it up and down and moving it back and forth, each operation is simple and therefore these can be operated by simple control.

Since the row-shaped grafted seedling pots 2a are transferred one row at a time from the terminal end of the rootstock carrying means 12 to the grafted feeding means, the handling amount per one time is large and the efficiency is improved.

Since the distance between the stock means for the rootstock and the scion and the transport means for the rootstock and the scion can be freely set, a large number of rootstock seedlings or scion seedlings can be stocked as stock means at one time. .

Since the stock stock means and the scion stock means are connected and supported by the gate type frames 32 and 33, both stock means can be reliably supported.

A processing unit having a cutting blade is provided between the two conveyors 12, 13 so that the cutting seedling and the rootstock seedling can be shared by one cutting blade.

[0048]

As is apparent from the above description, according to the present invention, the rootstock stocking means and the ears are arranged at the starting end thereof with the rootstock conveying means and the earring conveying means arranged in parallel. While arranging the tree stock means at right angles,
Grafting seedling stock means is arranged orthogonally to the end portion of the rootstock conveying means, and each row is connected from the rootstock stocking means and the scion stocking means to the rootstock conveying means and the scion conveying means. Since it is provided with a rootstock supply means for transferring the seedling pots and a scion supply means, and a grafting supply means for transferring the grafted seedling pots in a row from the rootstock transport means to the grafted seedling stock means. , It is possible to continuously supply seedlings for seedlings and seedlings for scion and store the grafted seedlings, and the installation area of the device can be reduced. Further, a row-shaped seedling pot in which a large number of pots are continuously arranged in a row can be transferred from the supply means to the transportation means, and the row-shaped grafted seedling pots are arranged one row at a time from the transportation means to the grafted seedling stock means. Therefore, the grafted seedlings can be treated with high work efficiency.
