DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grafting safety device for a grafting machine.

[0002]

Conventionally, rootstock seedlings are supplied to a rootstock seedling support frame, and scion seedlings are supplied to a scion seedling support frame. When these rootstock seedlings and spikelet seedlings are supplied, The feed is detected by the rootstock seedling sensor and the earling seedling sensor, and the respective grafting mechanisms are started by this detection, and the rootstock seedlings and the earling seedlings are turned over to the predetermined positions by the respective grafting mechanisms. These rootstocks and spikelets are cut diagonally from a predetermined position separately by each cutting blade of each cutting mechanism, and these cut rootstocks and spikelets are separated from each other. The grafting mechanism is rotated to a predetermined position to join the cut portions, and the graft is terminated by holding the joined portion with a clip or the like, but does not have a special grafting safety device.

[0003]

In the grafting operation of a seedling with a grafting machine, one of the workers supplies rootstock seedlings to a rootstock seedling support frame, and the other worker receives seedlings. The seedlings are supplied to the scion seedling support frame, and the supplied rootstock seedlings and scion seedlings are detected by the rootstock seedling sensor and the scionling seedling sensor. The seedlings and the scion seedlings are pivotally moved to predetermined positions by the respective grafting mechanisms and stopped, and these stocks leave one side cotyledons and rooted stems, and the other side cotyledons and true leaves (buds). Is cut by the rotation of the cutting blade of the cutting mechanism for rootstock seedlings, and the spikelet leaves both cotyledons and true leaves (buds), and the predetermined position of the rooted stem is Cutting is performed by the rotation of the cutting blade of the cutting mechanism, and the cut rootstock seedlings and spikelets are rotated to predetermined positions by the respective grafting mechanisms to join the cut portions. The junction is pinched by a clip or the like grafting is completed, grafting already seedlings are discharged grafting operation is completed to a predetermined position.

In the grafting operation described above, for example, the supply positions of rootstock seedlings and spikelet seedlings are poor, and correction may be made after the supply. At this time, the rootstock seedling sensor and spikelet seedling sensor have already been corrected. If it is detected that the seedlings and spikelets have been supplied,
When each grafting mechanism is started, the operator may injure his hand with this grafting mechanism, but this is intended to prevent this danger.
