DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft clip for joining a scion and a stock.

[0002]

2. Description of the Related Art A rectangular projection is provided on an inner surface of a long groove formed in an opening and closing portion of a graft clip (see FIG. 6).

[0003]

However, in the above-described graft clip, it is difficult for the ring to come off when the ring enters the long groove beyond the projection of the other graft clip.

[0004]

SUMMARY OF THE INVENTION The present invention provides a graft clip which can be easily removed even when the graft clips are entangled with each other, and has the following technical means. That is, clip pieces 4 and 5 having an opening / closing portion 3 having a holding portion 2 on one side and a long groove 10 formed from the front end toward the rotation center portion are opposed to each other with the rotation center portion 1 interposed therebetween. A ring 7 is provided that separates and passes through both opening / closing portions 3 and whose leading end fits into a groove 6 provided on the back surface of the clip pieces 4 and 5. When the opening / closing portions 3 are approached, the grip portion 2 opens and the opening / closing portion 3 is moved away. The grafting clip is configured so that the grip portion 2 is closed, and a projection 9 having a slope 8 is provided on the inner surface of the long groove 10 of the opening / closing portion 3 toward the distal end side and approaches the other inner surface of the long groove 10.

[0005]

When the opening / closing portions 3 are brought closer to each other, the gripping portion 2 is opened, and when the opening / closing portion 3 is moved away, the gripping portion 2 is closed, and the gripping portion 2 grips the joint between the scion and the stock. The ring 7 may enter the long groove 10 on the rotation center side beyond the projection 9 of the other graft clip. In this case, the ring 7 is pulled toward the tip of the opening / closing section 3 (the side opposite to the rotation center section 1). Then, since the protrusion 9 located in the long groove is provided on the slope toward the front side,
The ring 7 can be removed from the slot 10 of another graft clip.

[0006]

[Effect] Even if the graft clip is entangled, it can be easily separated.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. First, the construction will be described. The grafting device 11 is provided with a rootstock seedling receiver 14 for receiving a rootstock seedling 13 on one side of the clip feeder 12 in plan view.
A scion seedling receiver 16 for receiving scion seedlings 15 is provided on the other side. The clip feeder 12 and the rootstock seedling receiver 1
And a stock transport device 17 for transporting the stock 13 to the joining position between the clip feeder 12 and the scion seedling receiver 1.
6 is provided with a scion seedling conveying device 18. In addition, a stock cutting device 19 is provided for cutting the predetermined position of the stock seedling 13 during the transfer of the stock transfer device 17, and a scion cutting the predetermined position of the scion seedling 15 during the transfer of the scion transfer device 18. A cutting device 20 is provided.

The graft clip 21 includes a pair of clip pieces 4, 5 and a ring 7 formed in a discontinuous ring shape and having a restoring force. The clip piece 4 has a grip portion 2 having a grip surface on one side and a U-shaped long groove 10 formed at the other end (opposite to the grip portion 2) on both sides of the rotation center portion 1 in front view. A vertically long opening / closing portion 3 is provided, and the rotation center portion 1, the grip portion 2, and the opening / closing portion 3 are integrally formed. In addition, the rotation center portion 1 is inflated inward and formed to be thick, and the tip portion is formed in a spherical shape. Recess 23 into which the rotation projection 22 fits on the other side.
Is provided.

A rectangular recess 24 is provided on the back surface of the rotation center portion 1 of the grip portion 2, and a groove 6 into which the tip of the ring 7 can be fitted is provided above the recess 24 at an intermediate portion in the left-right direction. . The clip piece 5 has a grip portion 2 having a gripping surface on one side and a U-shaped long groove 10 formed on the other end (on the side opposite to the grip portion 2) with the rotation center portion 1 interposed therebetween in a front view. The rotation center part 1, the grip part 2, and the opening / closing part 3 are integrally formed. Further, the rotation center portion 1 is inflated inward and formed to be thick, and when the gripping surface is opposed to the gripping surface of the clip piece 4, the tip portion is formed in a spherical shape so that the axial center is formed in the lateral direction. The turning projection 22 that fits into the recess 23 of the clip piece 4 is provided on one side in a side view, and the recess 23 that the turning projection 22 of the clip piece 4 fits is provided on the other side.

Reference numeral 25 denotes a plurality of projections provided on the respective inner surfaces of the opening and closing portions 3 of the clip pieces 4 and 5 on the tip side (the side opposite to the rotation center portion 1). The projection 9 is provided on the tip side of the opening / closing portion 3 of one clip (the clip 4 in the embodiment) and protrudes into the long groove 10. The projection 9 is formed on the slope 8 from the center of rotation toward the tip, and the tip is formed on a substantially vertical surface.

Next, the operation will be described. First, the manufacture of the graft clip 21 will be described. The gripping surfaces of both clip pieces 4 and 5 are opposed to each other, and the respective rotation projections 22 of the clip pieces 4 and 5 are fitted into the concave portions 23 of the other party, and the ring 7
Through the long groove 10 of both clip pieces 4 and 5, and the leading ends are fitted into the groove 6 of the clip piece 4 and the groove 6 of the clip piece 5. Then, the grip portions 2 of the clip pieces 4 and 5 rotate inward around the rotation center portion 1 by the force of the ring 7 and the grip surfaces contact.

Next, a description will be given of a case where the joint between the scion and the stock of the grafted seedling is grasped. First, when a large number of graft clips 21 are supplied to the clip feeder 12 and driven, the graft clips 21 are sent to the joining side and aligned in a line. Then, when the worker supplies the rootstock seedling 13 to the rootstock seedling receiver 14 and supplies the earling seedling 15 to the earling seedling receiver 16 and turns on a work switch (not shown), the rootstock transport is performed. Device 17
Holds the rootstock seedling 13 and transports it to the joining side, and the scion transport device 1
8 holds the scion seedlings 15 and transports them to the joining side.

At the time of this transportation, the rootstock seedling 1
3 is cut at a predetermined position by a stock cutting device 19, and the scion seedling 15 is cut at a predetermined position by a scion cutting device 20. Then, when reaching the joining position, the joining surfaces of the rootstock seedling 13 and the scionling seedling 15 are in a state of being joined. Subsequently, the grafting clip 21 is sent out, and the gripping surface of the gripping portion 2 grips the joining surface between the rootstock seedling 13 and the scionling seedling 15 to complete the grafting operation (see FIG. 4).

The ring 7 of the graft clip 21 may enter the slot 10 of another graft clip 21 (see FIG. 6). The graft clip conventionally considered has a configuration in which a projection 9 is provided as shown in FIG. 5 so that it is difficult to enter the long groove, but once it enters, the surface of the projection 9 on the rotation center side is formed as a substantially vertical surface. It was difficult to remove it out of the slot.

In this embodiment, since the projection 9 is provided on the slope, the ring 7 can be easily detached from the long groove 10 by pulling the ring 7 along the slope 8 to the tip side, and the loss of the graft clip 21 can be prevented.
