BACKGROUND OF THE INVENTION Grafting is a method of adhering a part of a plant to another plant and mixing them to obtain a plant having desired properties.
As a result, it is possible to control tree vigor, promote flowering, increase the amount of results, improve quality, etc., and have been widely used since ancient times. Such grafting is usually carried out manually. Specifically, use hand scissors (for example, hand scissors capable of cutting wedge-shaped by moving the blade part in a diagonal direction) to cut the joints of the rootstock and the scion into a predetermined joint shape. A work is performed in which the joint is cut by a work, the joints of the rootstock and the scion are cut, and the positions of the joints are manually fixed while fixing the portions.

[0003]

When grafting is carried out by such manual work, the rootstock and the scion are usually small in size, so the work corresponding to the joining of the rootstock and the scion is cut into a predetermined bonding shape. And it is necessary to pay close attention to the work of aligning the positions of both the cut rootstock and the cut root of the scion, which imposes a mental burden on the worker, and also pays close attention. There is a problem that it takes a considerable amount of time to perform the work (specifically, one grafting takes about 1 minute).
Further, there is a problem in that the quality of the resulting graft varies depending on the individual difference of the worker in such work. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an automatic grafting device that can solve the above problems all at once.

[0004]

SUMMARY OF THE INVENTION An automatic grafting device according to the present invention is a holding means for individually holding a rootstock and a spike, and a rootstock and a rootstock while holding the rootstock and the spike in the holding means. Cutting means for respectively cutting the joint-corresponding parts into a predetermined joint shape, positioning means for aligning the positions of the rootstock and the earstock while holding them by the holding means, and a base in which the positions of both joints are aligned It is characterized in that it is provided with a fixing means for fixing the joint portion of the tree and the scion.

[0005]

When the grafting is performed by using such a device, the rootstock and the scion are individually held by the holding means capable of mechanically high-accuracy positioning. Can be placed in a highly precise position. Then, while holding the rootstock and the scion with the holding means, the joint corresponding portion of the rootstock and the scion is cut into a predetermined shape by the cutting means, and the relative position of the rootstock and the scion is further cut. By mechanically aligning and fixing the cut joints by changing the distance, the work can be performed accurately and quickly.

[0006]

Therefore, when grafting is performed by using such a device, cutting of a portion corresponding to the joining of the rootstock and the scion and positioning of the joining portion are accurately performed, and the quality of the resulting graft is obtained. Will be excellent with no variations. Further, since each work is mechanically performed, quick grafting can be performed and the efficiency thereof can be significantly improved (specifically, one grafting can be completed in 15 to 20 seconds). ). Further, the operator only has to mechanically manage the device, and the mental burden as in the conventional case is not applied.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic grafting device for grafting a scion on a rootstock.

[0002]

BACKGROUND OF THE INVENTION Grafting is a method of joining a part of a plant (spindle) to another plant (rootstock) to obtain a plant having a desired property, thereby controlling the vigor and promoting flower setting. It has been widely used since ancient times because it can increase the amount of results and improve the quality. An example of an automatic grafting device that automatically performs the grafting process described above is disclosed in Japanese Utility Model Laid-Open No. 61-31038. In this automatic grafting device, as shown in FIG. 18 of the above publication, the stem portion of the scion is cut into a wedge shape, and a hole is made in the upper end surface of the stem portion of the root tree to make the stem portion of the root tree The hole on the upper end surface of the section is configured to be grafted.

[0003]

As described above, when making a hole in the upper end surface of the stem of the rootstock, the diameter of this hole is smaller than the diameter of the stem of the rootstock, and the hole itself is very small. Since the size is small, the above-mentioned automatic grafting device is in a state in which the stem portion of the scion is joined to the small hole on the upper end surface of the stem portion of the rootstock. On the other hand, the stems of the rootstock and the stems of the scion are often in a different orientation and tend to change direction easily. In many cases, it is difficult to join the stems of the rootstock and the stems of the scion. Furthermore, in a rootstock that can be called a small seedling, it is actually difficult to make a small hole in a very narrow area called the upper end surface of the thin stem of this rootstock.

Further, in the above-mentioned automatic grafting device, all the cotyledons of the rootstock are left when the upper end surface of the root of the rootstock is punched, so that the cotyledons of the rootstock grow after the grafting treatment. Occasionally, the growth of the cotyledons of this rootstock may hinder the growth of the scion. An object of the present invention is to configure an automatic grafting device such that the growth of cotyledons of the rootstock does not hinder the growth of the rootstock so that the rootstock and the rootstock can be successfully joined.

[0005]

A feature of the present invention is that the automatic grafting device is configured as follows. [1] Root cutting means for cutting a joint-corresponding portion into a predetermined joint shape, a joint-corresponding portion of a rootstock cut into a predetermined joint shape, and a joint-corresponding portion of a rootstock are joined to each other And means.

[2] Root cutting means for cutting a joint-corresponding portion of which the tip side has been roughly cut into a predetermined joint shape, a joint-corresponding portion of the root joint cut into a predetermined joint shape, and a joint of a spike And a joining means for joining corresponding portions to each other.

[0007]

[I] [I] When the construction is such that the upper end surface of the stem of the rootstock is perforated as in the automatic grafting device described in Japanese Utility Model Laid-Open No. 61-31038, the stem of the scion is joined. The only possible part is the small part called the hole mentioned above. On the other hand, according to the feature of claim 1, the joint-corresponding portion of the rootstock is cut into a predetermined joint shape, and the joint-corresponding portion of the rootstock cut into the predetermined joint shape and the joint-corresponding portion of the scion are cut. To be joined. In this case, by diagonally cutting the joint-corresponding portion of the rootstock, it is possible to make the portion where the joint-corresponding portion of the rootstock can be joined larger than the small portion called the hole. As a result, the joining of the rootstock and the scion is hindered without being affected by the condition of the stem of the rootstock and the stem of the scion, which are different in orientation and tend to change direction. Can be done reliably without

[0008] In the case of the structure of cutting the joint corresponding portion of the rootstock into a predetermined joint shape as in the feature of claim 1, the target of the cutting is the very narrow range called the upper end surface of the stem of the rootstock. Instead, the relatively wide area of the entire stem of the rootstock (corresponding to the joint) is to be cut. As a result, the joint-equivalent portions of the rootstock can be cut into the predetermined joint shape without hindrance, without being affected by the condition of the stem of the rootstock, which has different orientations and is soft and easy to change direction. can do.

According to the first aspect of the present invention, when the roots of the rootstock (part or all) are cut off when the roots of the rootstock are cut into a predetermined joint shape, the rootstock can be processed after the grafting. Since it is less likely that the cotyledon will grow, the growth of the cotyledon of the rootstock does not prevent the growth of the scion.

[II] According to the feature of the second aspect, similar to the case of the first aspect, it has the "action" described in the above-mentioned [I], and additionally has the following "action" in addition to this. ing. According to the feature of claim 2, the joint-corresponding portion of which the tip side is roughly cut is cut into a predetermined joint shape. If the tip side (cotyledons, etc.) of the rootstock is roughly cut in advance in this way, the tip side (cotyledons, etc.) of the rootstock will be cut when the section corresponding to the joining of the rootstock is cut into a predetermined joint shape by the rootstock cutting means. ) Does not interfere with the root cutting means.

[0011]

According to the first aspect of the present invention, the joint-corresponding portion of the scion can be joined by cutting the joint-corresponding portion into a predetermined joint shape and performing the grafting process. The part could be made large, and the target of cutting could be a relatively wide range of the entire stem of the rootstock (corresponding to the joint). As a result, the prescribed joining shape of the joining equivalent part of the rootstock is not affected by the state of the stem of the rootstock and the stem of the scion, which are different in orientation and tend to change direction. It has become possible to reliably cut and join the rootstock and the scion without any problems, and it has been possible to suppress the defective rate of the grafting process in the automatic grafting device. According to the feature of claim 1, when cutting the joint-corresponding part of the rootstock into a predetermined joint shape, the cotyledons (part or all) of the rootstock can be cut off. It was possible to prevent a situation where the growth hinders the growth of the scion, and it was possible to improve the survival rate of the automatic grafting device.

According to the feature of claim 2, the "effect of the invention" of the above-mentioned claim 1 is provided as in the case of claim 1, and in addition to this, the following "effect of the invention" is provided. . According to the feature of claim 2, the rootstock is constructed by cutting the joint-corresponding portion into a predetermined joint shape in a state where the tip end side (cotyledons, etc.) of the rootstock has been roughly cut in advance. It becomes possible for the rootstock cutting means to accurately cut the joint-corresponding portion of the rootstock into a predetermined joint shape without being disturbed by the tip end side (cotyledons or the like) of the rootstock. As a result, the rootstock and the scion can be joined more accurately, and the survival rate of the automatic grafting device can be further improved.

After the flower pot 11 is translated, a root cutter 72 '(corresponding to a root cutting means) cuts a portion corresponding to the joint of the root A into a predetermined joint shape, a root cutting position S2, the flower pot 1
After 1 is further moved in parallel, while the scion B is held by the scion holding means 62 ′ in order to supply the scion B to the rootstock A, the portion corresponding to the splicing B is joined to the scion cutter 71. The scoop holding cutting position S3 is provided for cutting into a predetermined joint shape by using '.

Using a swivel arm 21 (corresponding to a joining means) that swivels 180 ° with respect to the rootstock A, which has been cut into a predetermined joining shape at a portion corresponding to a joint, the ears whose corresponding portions are cut into a predetermined joining shape. After turning 180 degrees to align the tree B, the turning arm 21 is moved in parallel, and the fixing medium is fed from the fixing device 91 ′ to the joint portion of the rootstock A and the scion B, and the base is fixed by the fixing medium. There are provided an alignment fixing position S4 for fixing the joint between the tree A and the scion B, and a removal position S5 for taking out the rootstock A on which the scion B is grafted together with the flowerpot 11.

The rootstock cutter 72 'is mounted on the tilt base 22 together with the swivel arm 21 and the earstock cutter 71',
By moving the rotary blade in parallel along the inclined surface of the sloping table 22 so as to approach the pedestal A side, the joining corresponding portion of the pedestal A is cut into a predetermined joining shape. The information on the parallel movement distance of the rotary blade at the time of cutting is used when the scion B is aligned with the rootstock A at the alignment fixed position S4.

In this case, the alignment fixed position S4
At the same time, while holding the cuttings B cut by the cuttings cutter 71 ′, the turning arm 21 is rotated downward by 180 °, and the roots A along the inclined surface of the tilting table 22.
The position corresponding to the joint of the rootstock A and the scion B is aligned by parallel movement to the side, and the amount of parallel movement is set based on the above-mentioned information.
