Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft seedling producing apparatus for fixing a rootstock stem and a scion stalk by joining them at cut surface portions thereof.

[0002]

2. Description of the Related Art Conventionally, as a grafting plant producing device for joining a rootstock stem and a scion stem at their cut surface points, and fixing the joining point with a clip, Japanese Patent Laid-Open No. 2-10
7125, JP-A-4-187029 and JP-A-4-304817.

The common point of these devices is that one scion and the rootstock are sequentially joined and fixed by a clip, which is inefficient because it is impossible to graft a plurality of seedlings at once. was there. Therefore, the applicant of the present application has previously described in Japanese Patent Application No. 5-291922 a grafting that can perform work such as cutting, joining, and fixing clips of a plurality of spikes and rootstocks at once in order to improve work efficiency. Proposed the structure of seedling production equipment.

In this grafted seedling production apparatus, a scion seedling transfer line, a rootstock seedling transfer line, and a grafted seedling transfer line are arranged in parallel in a plan view, and each line has a scion and a stand. A tray in which a plurality of tree seedlings are planted in a row so as to intersect the seedling transport direction is placed, and a frame provided so as to straddle the above three transport lines has a stem of each seedling. A gripping transfer mechanism for gripping the parts, a cutting mechanism for cutting the stalks of each seedling at the same height position, and a clip transport mechanism for grafting are moved laterally in parallel with the row-shaped seedlings. It is arranged as possible.

According to this structure, the stem between the upper and lower grips is cut in a state where the middle of the stem of the root from the seedling transfer line for the root is gripped by the pair of upper and lower gripping means. Similarly, the stem between the upper and lower grips is cut in a state where the middle of the stem of the scion is gripped and lifted by the pair of gripping means from the seedling conveying line for the scion. Among these cut pieces, the stem of the rootstock side of the rootstock and the stem upper side of the scion side are joined and sandwiched by clips to be grafted. In this case, to discard the upper part of the stem that is no longer needed and the root pot part that is also unnecessary in the spikelet, discard each stem of the rootstock and the spikelet by each lateral movement type gripping transfer mechanism. The unnecessary part of the upper part of the stem and the root pot part are discarded by gripping the part and laterally moving it to the top of the waste box, and then releasing the grip.

[0006]

However, in general, since the rootstock used is a rootstock grown until the stem becomes thick to some extent, the rootstock leaves planted in the tray are prosperous, so that the tray pot There was a risk of missing a rootstock stock in the club. Further, since the unnecessary height of the upper part of the stem is long and it is bulky due to the thickening of leaves, if the interval between the root pots in the tray in the left-right direction and the front-rear direction is narrow, the stem is straightened. In addition, in many cases, they are not arranged at regular intervals, so that the gripping operation by the gripping transfer mechanism cannot be performed reliably, and the upper part of the stem is caught by other parts during lateral movement by the gripping transfer mechanism. There is a possibility that various troubles may occur such as occurrence of.

Further, in the above-mentioned prior art, the spikes are lifted together with the unnecessary root pots by the gripping transfer mechanism from the seedling transport line for the scion and then cut, and the root pots are transferred to the seedling transport line for the rootstock. However, if the lowering work cannot be performed smoothly, this unnecessary root pot will be carried around to the scion seedling transportation line again, and the next time There was a problem that the scooping and lifting work could not be carried out smoothly.

The present invention has been made in order to solve these problems, and improves work efficiency by performing operations such as cutting, joining, and fixing clips of a plurality of spikes and rootstocks at once. An object of the present invention is to provide a graft seedling production apparatus capable of reliably carrying out grafting work.

On the other hand, in the dust removing device 82, a rotary brush may be arranged in front of the suction port 92a of the suction box 92 to scrape off the cut chips such as the upper stems toward the suction box 92. .

In the gripping transfer mechanism 7, which will be described later in detail, 6 trays H for seedlings and 6 seedlings for rootstock D are provided from the trays 5 and 5 in the seedling transport line 2 for seedlings and the seedling transport line 3 for rootstocks. 6
This is for grasping a total of 12 seedlings at a time, and in this grasping and transferring mechanism 7, the root side and the tip (upper side) stems (upper and lower two places) of one seedling are moved up and down. The gripping hands 15 and 16 sandwich the gripping hands. This upper gripping hand 1
The upper transfer frame 17 supporting the fifth group and the lower transfer frame 18 supporting the lower gripping hand 16 group are integrally lifted by a dimension H1 (not shown) (see FIGS. 6 and 8).

In the seedling transfer line 3 for the rootstock, as shown in FIG. 6, the seedlings sandwiched by the upper and lower gripping hands 15 and 16 are extracted upward from the pot portion 20 of the tray 5, and then the upper portion of the tray 5 is removed. In the space, the cutter 19 of the cutting mechanism 8 is pushed between the upper and lower gripping hands 15 and 16 to move the cutter 1 at once.
The stems of the two seedlings are cut diagonally with respect to their axis. As described above, in the rootstock preliminary tip device 81, the upper part of the stalk has already disappeared, so after cutting by the cutting mechanism 8, only the short stalk is gripped by the upper gripping hand 15.

On the other hand, in the scion seedling conveying line 2, as shown in FIGS. 9 and 13 and described later, a razor or the like as a scion preliminary cutting device provided on the lower end side of the lower gripping hand 16 is fixed. When sandwiching the stem of the scion with the blade 95, the stem in the vicinity of the root pot portion 20a is cut, and the pot portion 20 of the tray 5 is cut.
In addition, while leaving the unnecessary root pot portion 20a, only the leaf stem portion is gripped by the vertical gripping hands 15 and 16 and lifted by a predetermined distance H1, and then in the space above the tray 5, the vertical gripping hand 15 and 16.

On the other hand, the upper transfer frame 17 of the upper gripping hand group 15 is slightly raised by a dimension H2 (not shown) while holding the upper side stalks of the 12 seedlings with the stalks cut, and then the ears. The distance L2 (the distance L1 is set so that the upper side stem of the tree seedling H is located above the tray 5 of the grafted seedling transport line 4 and the upper side stem of the rootstock seedling D is located on the waste box 12). After moving laterally by 2 times), the upper gripping hand 15 group is arranged so that the upper side stem of the seedling H for scion joins the cut surface of the lower side stem portion (with soil) of the seedling D for rootstock. It is lowered by a predetermined dimension H2. In this state, above the tray 5 of the grafted seedling transport line 4, the clip 10 preloaded in the clip transport mechanism 9 is brought close to the joints of the seedlings and fixed so as to be sandwiched and fixed. It becomes the seedling S.

In this way, the six grafted seedlings S that have completed the grafting work are moved down the gripping transfer mechanism 7 by the distance H1, and the empty pots in the tray 5 of the grafted seedling transfer line 4 are removed. Since it is stored in the part 20, in this state,
The upper gripping hand 15 and the lower gripping hand 16 may be opened to release the grip of the stem. When the preliminary cutting device for spikes is not provided, the rooting portion 20a and the tray 5 are pulled out from the tray 5 in the gripping transfer mechanism 7 for the spikelet seedlings H.
At this time, the root pot portion 20a of the seedling H for the spike is no longer needed.
Is stored in the empty pot portion 20 of the tray 5 from which the rootstock seedlings D have been extracted in the rootstock seedling transfer line 3 by the opening movement of the lower gripping hand 16, and is no longer needed. The tip side stalk of the seedling D is naturally dropped toward the waste box 12 by the opening movement of the upper gripping hand 15 and is discarded.

Next, the detailed structure of the gripping transfer mechanism 7 will be described with reference to FIGS. The lifting / lowering frame 21 of the grip transfer mechanism 7 includes a first lifting / lowering actuator 22 such as a lifting / lowering air cylinder fixed to the upper surface plate of the gate-shaped frame 6.

On the moving frame 61, a clip holder 70 consisting of six pairs of left and right hand bodies 70a and 70b is arranged at a constant interval (P2) equal to the installation interval of the upper gripping hand 15 (lower gripping hand 16) in the gripping transfer mechanism 7. ) Is arranged. The horizontal rods 71 to which the bases of the six right hand bodies 70b are fixed and the horizontal rods 72 to which the bases of the six left hand bodies 70a are also fixed are attached to the moving frame body 60 so that they can move from side to side. ing.

On the other hand, the left and right hand bodies 70a and 70b of each clip holder 70 are opened inward with each other.
Guide grooves 76, 76 are formed in the longitudinal direction, and the split ring spring 10c of the clip 10 is inserted into the guide grooves 76, 76 and is held in the posture while the clip 10 is held.
The stem grasping portion 10a, which is the tip of, can move to the holding portion 77.

Then, as will be described later, the left and right hand bodies 70
In the state where the distance between a and 70b is maintained at P4, the supply port 11 of the supply passage 11a in the clip feeder 11
When located in front of b, the push body 79 at the tip of the piston rod 78a of the clip supply actuator 78 such as an air cylinder arranged along the supply passage 11a pushes the clip 10 forward and makes it inherited by the clip holder 70 ( 19 (a)).

At this time, the base portion of the opening / closing operation portion 10b is arranged so as to be connected to the middle portion in the height direction of the stem grip portion 10a, and is made of a spring plate fixed to the base portion of each clip holder 70. The clip restricting body 103 is disposed below the pair of left and right hand bodies 70a and 70b so as to extend toward the tip (free end) side thereof.
The tip end side of the
It is arranged so that the tip of 3 abuts on the lower end of the connecting portion of the stem gripping portion 10a of each clip 10 and the base of the opening / closing operation portion 10b. In addition, the clip regulating body 10 at this time
As shown in FIGS. 19B and 19C, the tip end surface of 3 is arranged so as to be parallel to the tip ends of the left and right hand bodies 70a and 70b in a plan view and protrude by a distance L3. .

When the transfer of one clip 10 to one clip holder 70 is completed, the step motor 66 is operated to move the entire moving frame 60 to the pitch P.
The clip holder 70 in the empty state is positioned in front of the supply port 11b by intermittently moving in the lateral direction (X direction) by 2, and the clip 10 is inherited by the clip holder 70. When the clip 10 is supplied to all 70, the moving frame 61 is enlarged toward the front of the gripping transfer mechanism 6 in a state where the cutting points of the rootstock seedling D and the scion seedling H are joined. It is moved in the X direction. The piston rod 73a protruding from the left side of the first clip actuator 73 such as an air cylinder fixed to the moving frame 61 is connected to the second clip actuator 74, and the piston rod 74a of the second clip actuator 74 is connected to the lateral side. A piston rod 73b that is connected to the rod 71 and projects from the right side
Is connected to the second clip actuator 75, and
Piston rod 75a of the clip actuator 75
Is connected to the horizontal rod 72. As a result, when the piston rods 73a and 73b project from each other, the distance between the left and right hand bodies 70a and 70b is reduced to P3 (see the state of FIG. 19B), and the left and right opening / closing operation portions 10b and 10b of the clip 10 are closed. The interval between the stems is narrowed, and the stem grip portion 10a
Can be held in an expanded state. Both piston rods 73
When a and 73b retreat from each other, the left and right hand bodies 70
The lateral distance between a and 70b has expanded to P4 (see the state in FIG. 19A), and the clip feeder 11 is in a standby position in which the clip 10 is inherited from the supply port 11b. Then, in this expanded state, the second clip actuators 74, 75 are operated to operate the piston rods 74a, 75.
When a is moved so as to project, the left-right spacing between the left and right hand bodies 70a, 70b expands to P5 (see the state in FIG. 19C), and the joint portion of the grafted seedling S is joined from the left and right at the stem gripping portion 10a of the clip 10. Grab and fix. When the piston rods 74a and 75a are moved backward, the left and right hand bodies 70
The distance between the left and right sides of a and 70b is narrowed down to P4 (see the state of FIG. 19B), and the system is restored.

As described above, the left and right hand bodies 70a, 70
When the left-right space of b is widened, the free end side (the most widened part) of the opening / closing operation parts 10b, 10b of the clip 10 is opened and closed by the tip of the clip restricting body 103 and the stem grasping part 10a of the clip 10. Unless the location of the portion of the portion 10b that is continuous with the base is abutted against the left and right holding portions 77, 77, the distance from the tips of the hand bodies 70a, 70b remains constant. The rotation fulcrum of the grip portion 10a (in other words, the hand bodies 70a, 70
The turning fulcrum of b) approaches the tips of the hand bodies 70a and 70b as the tip ends of the left and right stem gripping portions 10a narrow. Therefore, in this case, as the tip ends of the left and right stalk gripping portions 10a, 10a become narrower, the position of the stalk is deviated so as to become shorter than the position where the stalks are gripped by the left and right stalk gripping portions 10a, 10a. As a result, it becomes impossible to reliably carry out the work of gripping the stem. Therefore, if the clip 10 is regulated by the tip edge of the clip regulating body 103 so as not to approach the tip side of the hand bodies 70a and 70b, the stem grasping work can be surely executed. Further, the tip edge of the clip restricting body 103 has the left and right stalk gripping portions 1
0a and the base portion of the opening / closing operation portion 10b are brought into contact with each other, so that the contact release timing between one holding portion 77 and the hand body 70a when the hand bodies 70a and 70b are opened and moved. Even if the contact release timing between the other holding part 77 and the hand body 70a is deviated, the left and right stalk gripping parts 1
There is no deviation in posture so that 0a and 10a rotate in a plan view.

With the above structure, the gripping transfer mechanism 7
A total of 12 stalks of 6 sapling seedlings H and 6 rootstock seedlings D are sandwiched between the upper gripping hands 15 and the lower portion 16 and picked up from the tray 5, and the middle of the stalks is cut. After cutting the part, and moving the upper part of the stem slightly after lifting, the upper part of the stem is moved by a distance of L2, and the lower part of the stem is laterally moved by a distance L1. During the process of lowering and joining the upper part of the stem of the scion seedling H to the cutting surface of the lower part of the stem of the rootstock D, the clip transport mechanism 9 clips the six clips 10 from the clip feeder 11. After being loaded in the holder 70, the process of moving in the X direction to approach the junction of the six seedlings is simultaneously advanced.

In this case, on the upstream side of the seedling transport line 3 for the rootstock, the unnecessary upper part of the stem is previously cut by the rootstock preliminary cutting device 81 and removed by the scrap removing device 82. In this case, the leaves on the upper part of the stem do not get in the way, and the stem part of the rootstock is sandwiched by the gripping transfer mechanism 7 on the downstream side of the conveyance to fix the root pot part 20.
It is possible to surely perform the work of raising and moving laterally. In this case, if the height position of the sub-column 84a with respect to the main column 83a is changed, the height position of the cross beam 48 and the cutting height position of the rootstock preliminary cutting device 81 can be changed. The height from the upper surface of the seedbed to the cut surface of the rootstock can be changed and adjusted to a suitable dimension.

The lower gripping hand 1 for gripping the lower part of the stem of the gripping transfer mechanism 7 in the scion seedling conveying line 2.
6 is provided with a fixed blade 95 on the lower clamping piece 37b, the upper part of the stem of the spikelet seedling H is clamped and transferred while leaving the unnecessary root pot 20a in the pot 20 of the tray 5. As a result, it is possible to eliminate the inconvenience caused by carrying around the unnecessary root pot 20a as in the conventional technique.

When the grafting work of fixing the joints of the six seedlings with the clip 10 is completed, the clip transport mechanism 9 returns to the original position and the clip loading work is executed. In the meantime, by lowering the grip transfer mechanism 7 by a distance of H1, the grafted work finished 6 is finished.
The seedlings S of the book are stored in the empty pot portion 20 of the tray 5 of the grafted seedling transport line 4, so in this state, if the upper gripping hand 15 and the lower gripping hand 16 are opened, gripping of the stem is released. good.

In the embodiment in which the rootstock pre-cutting device 81 and the scrap removing device 82 are provided in the rootstock seedling transfer line 3 described above, the gripping transfer mechanism 7 in the scion seedling transfer line 2 is used.
In the case where the stem cutting pre-cutting device for cutting the lower part of the stem is not provided, the root pot portion 20a of the spear seedling H which becomes unnecessary is used for the rootstock by the opening movement of the lower gripping hand 16 after lateral movement. Tray 5 from which seedling D for seedlings has been extracted in seedling transfer line 3
Will be stored in the empty pot section 20.

Further, the grasping and transferring mechanism 7 in the scion seedling conveying line 2 is provided with a scion preliminary cutting device for cutting the lower part of the stem, while the scion seedling conveying line 3 is provided with a stock preliminary cutting device 81 and scraps. In the case where the removing device 82 is not provided, the tip end side stalk of the rootstock seedling D that has become unnecessary due to the opening movement of the lower gripping hand 16 after the lateral movement moves to the upper gripping hand 15
When it is opened, it falls naturally toward the waste box 12 and is discarded.

In the above embodiment, an apparatus capable of simultaneously producing 6 grafted seedlings has been described, but the number can be increased or decreased depending on the required area of the installation section.
