Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rootstock seedling tray and a rootstock seedling tray, which are rootstock seedlings and a rootstock seedling grown in a lattice shape in the width direction and the length direction, on a rootstock line and a rootstock line. It is placed and transported, and each of the rootstock seedlings and scion seedlings in each tray is clamped in a row by the clamp means that is inserted in a direction perpendicular to the tray transport direction, and the upper surface of the rootstock side clamp means is clamped. Along with the rootstock cutting device, also cut along the lower surface of the scion side clamping means by the scion cutting device, the cut scion seedlings were clamped on the rootstock side clamping means. The present invention relates to a grafting device and a grafting method for moving a clamp means to join cut surfaces of a rootstock seedling and a scion seedling.

2. Description of the Related Art In this type of grafting device, all seedlings are sown and grown in a grid in a seedling raising tray in an orderly manner, but the growth directions of individual seedlings are not uniform depending on the germination direction. It may grow up with a tilt.

In this type of conventional grafting device, the rootstock seedling is
Before being carried into the above-mentioned stock line, an unnecessary tip portion was cut by a preliminary cutting device or the like to be carried into a stock state as a stock.

Further, in the above-mentioned conventional grafting apparatus, grafted seedlings obtained by joining the rootstock seedlings to the rootstock seedlings are discharged to the seedling raising tray on the rootstock seedling side while being rooted.

In addition, when the grafting operation is performed on the rootstock line, there is no means for removing the scion seedlings when the seedlings are cut or adhesive failure occurs. There is also an adverse effect, and in order to prevent it, the workers had to remove the poorly adherent seedlings individually.

[0006] In the conventional grafting device, an adhesive agent is immediately applied to the rootstock seedling and the scion seedling in contact with each other, and then a curing agent is sprayed to spread the adhesive agent to cure it. Was there.

At the tip of the adhesive nozzle for discharging the adhesive, there is a tape-shaped mesh member for stripping off the adhesive which has adhered to the tip of the adhesive nozzle and has begun to cure.
It is provided so as to move while being in contact with the adhesive nozzles at regular intervals, and the adhesive passes through this mesh member and is discharged, and the adhesive nozzles are arranged in the above-mentioned rows. There were as many seedlings as there were, and each was provided integrally with the machine frame.

Each nozzle tube connected to the adhesive nozzle is inserted and supported in the machine frame supporting the adhesive nozzle.

[0009]

The conventional technique of the above-mentioned conventional grafting device has the following problems. (1) The rootstock clamping device and the rootstock clamping device for clamping the rootstock seedlings and the rootstock seedlings should be able to normally clamp even when the rootstock seedlings and the rootstock seedlings are slightly inclined when the clamps are activated. The opposing clamp portions are V-shaped and can be clamped while guiding the slanted seedlings on the slopes on both sides thereof.

The range of guiding rootstock seedlings and scion seedlings by the clamp means can be set largely in the moving direction of the seedling raising tray (longitudinal direction of the seedling raising tray) due to the opening / closing operation of the clamp plate. In the direction perpendicular to the moving direction (width direction of the seedling raising tray), the opening width of the clamp portion was too large to be large.

Therefore, in the conventional technique in which the rootstock seedlings and the spikelet seedlings are brought into each line in the natural seedling raising state in each seedling raising tray, each seedling raising tray in each seedling raising tray is If the seedlings are tilted in the direction perpendicular to the moving direction of the seedling raising tray and beyond the guiding range of the above clamping devices in this direction, the seedlings cannot be clamped, and thus the rootstock seedlings and the scion seedlings are grafted. However, there was a problem in that the clamp was defective.

(2) Further, in the grafting device using the above-mentioned conventional grafting device, like a sapling of the Cucurbitaceae, the grafted seedlings that have been grafted are rooted and inserted into a seedling raising tray to grow. In this case, the stem of the rootstock had to be manually cut and re-inserted in the seedling raising tray at the end of grafting, which was troublesome and inefficient.

(3) The seedlings with poor adhesion produced during the grafting work by the rootstock clamping means and the scion clamping means were removed by the workers one by one. Therefore, in order to improve the efficiency, the automatic grafting work is performed. It was a big problem for the purpose of doing.

(4) Further, since the sap comes out to each of the cut surfaces of the rootstock seedling and the scion seedling that have been cut, when the cut surfaces of both seedlings are butted, this sap produces It sticks to the surface of the stems of both seedlings.

For this reason, as in the prior art, the seedling seedlings cut by the respective cutting devices are brought into contact with the rootstock seedlings, and then immediately after the sap is adhered, an adhesive is applied to these portions. Then, this sap causes the adhesive to harden in unnecessary areas around the contact surfaces of both seedlings, and the contact surfaces around the contact ends of both seedlings cannot be firmly covered with the adhesive and adhere to each other. There were cases where defects occurred.

Further, the above-mentioned sap adheres to the adhesive remaining at the tip of the adhesive nozzle and solidifies the adhesive at this portion, so that the mesh member is moved at a high frequency to reach the tip of the adhesive nozzle. An operation is required to remove the solidified material of the cured adhesive.

(5) Further, the surface of the adhesive nozzle is
Since the mesh member continues to rub in order to strip off the solidified adhesive, the coating material such as the release agent coated on the tip of the adhesive nozzle is quickly released, which deteriorates the release property. If it comes, the mesh member will be cut off, and maintenance such as nozzle replacement will be required at an early stage. However, since the above-mentioned conventional adhesive nozzle is integrally fixed to the machine frame side, it cannot be replaced one by one and it is necessary to replace a plurality of them together, which is uneconomical.

(6) Further, in the above-mentioned conventional adhesive nozzle, the nozzle tube connected thereto is inserted and supported in the hole provided in the machine frame for supporting the adhesive nozzle. Connecting the nozzle tube to the nozzle during replacement is awkward and the workability is poor, and if the adhesive nozzle is fixed after inserting the nozzle tube, it is difficult to position the nozzle, and after fixing the nozzle, the nozzle is fixed. The problem of inserting the tube is that it is difficult to insert the nozzle tube into the hole.

In the first feed mode, the rootstock seedling 10 of the rootstock seedling tray 8 stops when it comes directly below the rootstock making device 19, then returns to the upstream side for several mm, and then returns to the pitch of the seedling row. The second feed mode has two types of feed operations in which the operation of moving to the downstream side by the amount added is repeated. The first feed mode is used at the time of rooted grafting, and the second feed mode is used at the time of rooted grafting.

The operation of the above configuration will be described below when the conveyor device 6b of the stock line 1 operates in the first feeding mode, that is, the rooted grafting operation. The stock 10 and the stock 11 are grown to a predetermined size in a greenhouse or the like in the stock 8 and the stock 9 respectively. At this time, the two seedlings 10 and 11 are reared neatly at the same interval in a grid pattern. The trays 8 and 9 where the seedlings were raised
Are stored in receiving trays 12 and 13, respectively, and supplied to the upstream side of each line 1 and 2.

Receiving tray 1 accommodating trays 8 and 9
2 and 13 are conveyed by the conveyors 6a and 7a of the lines 1 and 2, respectively. First, the stock 10 in the stock tray 8 in the stock line 1 is cut by the preliminary cutting device 4 at a position longer (higher) than the length as the stock.

At this time, in both lines 1 and 2, before the seedling trays 8 and 9 reach the respective seedling producing devices 19 and 20, in the grafting device 3, the tray aligning devices 161 and 161 are used on the lines. Are aligned in the width direction, and the sensors 165 and 165 perform positioning in the conveying direction, and then the seedling trays 8 and 9 are directed toward the seedling producing devices 19 and 20 at a pitch of one row in the conveying direction.

At this time, the rootstock seedlings 10 and the rootstock seedlings 11 before entering the rootstock guiding device 121a and the rootstock guiding device 121b.
Are inclined in the width direction of the tray, the guide pieces 12 of each pair
Since the tips of 2a and 122b are funnel-shaped, they are gradually corrected to an appropriate posture as the tray moves.

Next, each seedling making device 1 on both lines 1 and 2
The operation at 9, 20 will be described. Each of the seedling trays 8 and 9 conveyed at the above-mentioned feed pitch is connected to each of the seedling producing devices 1.
The seedlings are stopped for the seedling creation time in steps 9 and 20, and this stop time is the feed pitch interval. A predetermined seedling row of the seedling trays 8 and 9 of each line 1 and 2 is connected to each clamping device 2 of the grafting device 3.
In a state immediately below the lines 2 and 24, the conveyance of the lines 1 and 2 is stopped and the grafting operation is started.

The scion tray 9 and the stock tray 8 obtained by preliminarily cutting the tips 10a are moved to the tray positioning devices 161 and 161 on each line of the grafting device 3 in a synchronized state. While passing therethrough, the receiving trays 12 and 13 are positioned at predetermined positions in the width direction by the urging rollers 162, and the trays 8 and 9 are positioned by the pressing plate 164.

Each of the trays 8 and 9 positioned in the width direction as described above has the tray positioning devices 161 and 161.
After being conveyed further downstream, the subsequent trays 8 and 9 are detected by the sensors 165 and 165. These two sensors 161,
If the tray detection by 161 is simultaneous, the first conveyors 6b, 7b on both the stock side and the splint side intermittently start the transfer of the pots of the flower pots of the trays 8, 9 from that point in time. I do.

At this time, if the detections of both sensors 165 and 165 are deviated, the conveyor 6b of the one detected first is detected.
(7b) stops on the spot, and when the other sensor detects the tray, which has been delayed, the two conveyors 6b and 7b are operated intermittently as described above. In this way, the trays 8 and 9 on the stockstock side and the scion side are synchronized with each other and the conveyors 6b and 7 of the grafting device 3 are moved intermittently one row at a time.
b.

Of the above trays 8 and 9, the root tray 8
Rootstock seedlings 10 obtained by cutting the tip 10a of the rootstock
Then, it is clamped by the stock clamping device 22.
At this time, the first and second clamp devices 27 and 28 of the rootstock clamp plate device 26 of the rootstock clamp device 22 are inserted between the rootstock seedlings 10 in the tray 8 in an expanded state, and then the clamp operation is performed. By doing so, each clamp plate 31
The rootstock 10 is clamped by the clamps 37a and 37b a to 32b. Then, in this state, each clamp plate 3
The tips of 1a to 32b are clamped by a clamp device 30.

At this time, the first and second clamp plate devices 27 and 28 are operated separately, and the first and second clamp plate devices 27 and 28 are located below.
And then clamped by the first clamp plate device 27 located on the upper side. Thereby, even the bent rootstock seedling 10 can be clamped without difficulty.

Then, the rootstock cutting device 23 is operated,
The pre-cut rootstock seedling 10 is cut along the upper surface of the first clamp plate device 27 of the rootstock clamp plate device 26.

When the rootstock cutting device 23 is not used, the first cutting blade 104 located on the upper side moves the lifting rod 103 upward as shown by the chain line in FIGS. 6, 7 and 16. However, the clamp actuation device 5 of the scion clamp device 24
1a and 51b. Further, the second cutting blade 105 is rotated in the lateral direction.

When the grafted portion of the rootstock seedling 10 is cut, the second cutting blade 10 is cut as shown by the solid line in FIG.
5 is rotated downward in the horizontal direction to move the first cutting blade 104 down.
Is moved along the upper surface of the stock clamp plate device 26, and then the rodless cylinder 101 is operated to move the base 45 in the lateral direction. The plate is cut at a position along the upper surface of the plate device 26. After the cutting, the height is raised again to the standby state.

At this time, by rotating the second cutting blade 105 to the lower side of the root clamp plate device 26, the tip of the root seedling 10 is cut by the first cutting blade 104 and the root seedling 10 is cut. The root-root grafting operation is performed to create a root stock for root-root grafting. The root-root grafting operation by the root-root grafting rootstock will be described later.

On the other hand, the scion preparing device 20 operates in synchronization with the rootstock preparing device 19, and the scion seedling 11 of the scion tray 9 is used.
Is clamped by the scion clamp device 24, and then the cutting device 25 is positioned at a position along the lower surface of the scion clamp device 24.
Is cut at

At this time, since the scion seedling 11 located below the scion clamping device 24 is guided to the clamp position by the pair of guide pieces 122a and 122b of the scion guiding device 121b, the scion of the scion seedling 11 is guided. In the clamp portions 37a and 37b of each clamp plate of the clamp plate device 46,
It is clamped without deviating from this.

At this time, as shown in FIGS. 31 (a) and 31 (b), the clamping operation of the spike-clamp plate device 46 is stopped midway, and the spike-tree seedlings 11 are loosely clamped,
In this state, the cutting blade 65 of the cutting device 25 is lowered a little to cut the scion seedling 11 for a little longer, and then, as shown in FIGS. 32 (a) and 32 (b).
As shown in (3), the cutting operation is completed, and the long-cut cutting seedlings 11 are newly clamped, and the cutting blade 65 is raised to a position along the lower surface of the clamp plate to cut again.

By cutting by the two-step induction as described above, when the scion seedling 11 grows off the center of the flower pot as shown in FIG. 30 (b), it can be cut without damage. Further, according to this method, since the first stage cutting is not yet firmly clamped, each scion seedling 11 has its leaf portion clamped to the clamp plate by gravity as shown in FIGS. 32 (a) and 32 (b). It is dropped until it is caught on the tree, and in this state it is firmly clamped and the second step is cut, whereby a scion with a constant length from the leaf portion is obtained.

The cutting of the row of scion seedlings 11 clamped by the two-step induction is performed twice, but since the cutting blade 65 is a double-edged blade, both cuttings should be performed by the reciprocating motion of the cutting blade 65. You can When using a single blade, the cutting device may be run twice.

When the scion seedlings 11 are cut by the above operation, the scion clamp plate device 46 of the scion clamp device 24 maintains the clamped state by the clamp device 41, and as shown in FIG. The movement of the moving device 58 moves to the 1 side in parallel, and the positioning is stopped just above the root clamp plate device 26 that clamps the root seedling 10 in the cut state.

At this time, the scion clamp plate device 46
Moves under the stock cutting device 23 in the upward movement state and does not interfere therewith. Similarly, since the defective bonding seedling removing device 112 also moves upward, it does not interfere with the scion clamp plate device 46.

Then, the lifting device 5 of the spike-clamp device 24
7, the scion clamp plate device 46 descends, and the cut surface of the scion seedlings 11 clamped by the scion clamp plate device 46 becomes the rootstock clamp plate device 26.
The cut surface of the rootstock seedling 10 clamped to the abutment is brought into contact.

The parallel movement and lowering operation of the above-mentioned scion clamp device 24 are performed by the respective moving device 58 and elevating device 57.
Is performed by a positioning means (not shown) attached to the. Then, at this time, as shown in FIG. 15, the clamping device 41 of the scion clamping device 24 is changed to the root clamp device 30.
Are engaged and positioned.

In this state, the pair of first (upper) clamp pieces 38a of the clamp device 30 of the rootstock clamp device 22,
After unclamping 38b, the pair of clamp plates 31a and 31b of the first (upper) clamp plate device 27 of the stock clamp plate device 26 are unclamped, and the first clamp plate device 27 is attached to the stock line 1 Evacuate to the side.

At the same time, the second (lower) clamp plate device 46 of the spike-clamp device 24 is unclamped, and then the second (lower) clamp plate device 48 of the spike-clamp plate device 46 is paired. The clamp plates 50a and 50b are unclamped, and are evacuated to the side of the stock line 1 as in the case of the stock side.

[0106] As a result, the rootstock seedling 1 with the cut end face abutting
0 and the hogi seedling 11 are the second of the rootstock clamp plate device 26.
The clamp plates 32a and 32b of the (lower) clamp plate device 28 and the clamp plates 49a and 49b of the first (upper) clamp plate device 47 of the scion clamp plate device 48 will be clamped, and both seedlings 10 , 11 has a gap S (FIG. 23) extending over two clamp plates.

In the above operation, rootstock seedlings 10 and scion seedlings 1
Sap b exudes to the cut end face of No. 1 and the sap b overflows and adheres to the periphery of the contact portion due to the contact between the cut end faces of both seedlings.

In this state, the adhesive applying device 1 is applied to this portion.
When an adhesive is applied in step 8, the sap acts as a hardener and hardens where the adhesive is unnecessary, and good adhesion around the contact portion cannot be achieved.

From this, in the contact state of both seedlings, as shown in FIG. 33, first, the curing agent spray nozzle 85 of the adhesive applying device 18 is opposed to the contact portion of both seedlings, and the nozzle 8
Air 5 is jetted from 5 to blow out the sap b and remove it.

Next, after raising the hardening agent spraying nozzle 85, as shown in FIG. 23, the nozzle frame member 131 of the adhesive applying device 18 is made to face the abutting portion of both seedlings, and then this is applied to both seedlings. The adhesive c is discharged in the vicinity of the contact portion and applied in a dumpling shape on the contact portion.

At this time, the adhesive passes through the mesh member 88 interposed at the tip of the nozzle 76 and is supplied to the abutting portions of both seedlings 10, 11. Then, the nozzle 76 withdraws and slightly delays from this, and enters the state shown in FIG. 34. This time, the curing agent spray nozzle 85 sprays the curing agent d together with air to accelerate the curing of the adhesive. The adhesive applied in a dumpling shape is cured while being spread thinly on the peripheral surface of the joint portion by the curing agent blown with the air. Finally, after-blowing the air. As a result, the hardener remaining at the hardener outlet is discharged, and the remaining amount in the pipe is adjusted so that the hardener at the next time is maintained at a fixed amount, and the remaining hardener is used for the next sap blowing step. Prepare for air blast.

Since the adhesive adheres to the mesh member 88, it is wound up little by little each time the adhesive is discharged once or a plurality of times so that a new portion is always positioned at the tip of the nozzle. Thus, clogging of the adhesive nozzle 76 due to the curing of the adhesive can be prevented.

After applying the adhesive and curing it, the remaining clamp plate devices 28 and 47 of both the clamp plate devices 26 and 48 on the rootstock side and the scion side are unclamped to the side of the rootstock line 1. Evacuate to. At this time, if there is a bonding failure among the seedlings in one row, the scion seedlings 11 fall down and lean toward the clamp plate to be unclamped. If the clamp plate is pulled out to the side of the stock line 1 as it is, the fallen seedlings will be hooked by the clamps and will be pulled together, thereby defeating other seedlings that have been successfully grafted. This is prevented by the poor adhesion seedling removing device 112.

That is, as shown in FIG. 35, at the time of unclamping operation after the completion of adhesion, the adhesion-defective seedling removing device 112 is used.
The brush 115 is lowered between the clamp plates in the unclamped state, and the upper and lower clamp plate devices 28 and 47 of the clamp devices 22 and 24 are pulled out while rotating the brush 115.

As a result, the seedlings with poor grafting caused by the poor adhesion left between the plates or the absence of the rootstock are not found in the brush 1.
15 and is dropped and discharged to the side of the stock line 1. At this time, air may be blown from the brush 115. In this embodiment, the example of the poorly adhered seedling removing device 112 is fixed to the frame. However, the defective seedling removing device 112 is moved in the lateral direction without interfering with the rootstock cutting device 23 as in the above-mentioned rootstock cutting device 23. You may.

In the adhesive applying device 18, the mesh member 88 is the motor 1 of the mesh member winding device 139 every time the adhesive is discharged from the nozzle piece 134 of the nozzle frame member 131.
At this time, a certain amount is wound up. At this time, the feeding amount is counted by the encoder 142 of the mesh member feeding device 138 side, and when the encoder 142 counts a certain amount, the motor 140 is stopped by the signal. ing.

On the side of the motor 140 as well, if no signal is sent from the encoder 142 even if the motor 140 is operated for a certain period of time, for example, if the mesh member 88 is cut or the mesh member 88 disappears, the motor 140 is stopped. It is supposed to let you know. The encoder 142 counts the total amount of the feed, and can control the remaining amount of the mesh member 88.

If the mesh member 88 contains water, the adhesive will be easily hardened when the adhesive is applied to the joint portion of the seedling through the mesh member 88. In order not to absorb moisture, the moisturizing agent is sprayed while being wound on the bobbin 141.

As described above, the tip of the nozzle piece 134 is
By repeatedly rubbing with the mesh member 88, this film on the tip surface, which has been coated to prevent the adhesion of the adhesive, peels off, and the peelability of the adhesive deteriorates. Therefore, there is a problem that the mesh member 88 is broken.

Therefore, the nozzle piece 134 is regularly replaced. The nozzle pieces 134 are fitted into the nozzle frame member 131 in a detachable manner from the upper side, so that each nozzle piece 134 is individually replaced.

At this time, the nozzle tube 137 connected to the nozzle piece 134 is also the nozzle tube guide piece 135.
Since it is fitted in the groove 136 provided in the nozzle piece 13
4 can be easily detached from the nozzle frame member 131 together with the nozzle piece 134.
The nozzle tube 137 is contacted and separated. The above nozzle piece 1
In addition to the replacement of 34, the cleaning work is also carried out by detaching from the nozzle frame member 131 as in the above.

Next, with reference to FIG. 16, FIG. 36, FIG. 37 and FIG. 38, regarding the root grafting method using the grafting device having the above-mentioned structure and operating the conveyor device 6b in the stock line 1 in the second feed mode. And explain. The rootstock seedling tray 8 is transported to the grafting device 3, and the rootstock creating device 19 is provided.
The first cutting blade 10 on the upper side of the stock cutting device 23 at the time of the cutting action while being clamped by the stock clamping device 22 of FIG.
At the same time as the seam cutting by No. 4, the root of the rootstock 10 is cut by the lower second cutting blade 105 (FIG. 36).

At the time of this cutting action, the rootstock cutting device 2
3 is raised and lowered in a state where the second cutting blade 105 is rotated in the lateral direction, and in a state where the second cutting blade 105 is moved downward, the second cutting blade 105 is rotated so as to be positioned below the stock clamp device 22. The stock cutting device 23 is moved in the state.

[0124] By doing so, the root side of the rootstock seedlings 10 in a row in the lateral direction clamped by the rootstock clamping device is separated. Next, the stock cutting device 23 is retracted upward after rotating the second cutting blade 105 in the lateral direction. After that, in the same manner as the above-described ordinary rooted grafting operation, the ear tree seedling 1 is placed on the rootstock seedling 10 clamped by the rootstock clamping device 22.
1 is moved and bonded by the bonding device 18.

With the above grafting completed, the rootstock line 1
The conveyor device 6b is moved slightly (several mm) upstream (or downstream) in the transport direction to slightly shift the root-side cutting surface of the rootstock 10 in the traveling direction (FIG. 37).

Next, the conveyor device 6b of the stock line 1
Is raised by the lifting device 111. Thus, the root-side cut portion of the rootstock seedling 10 is inserted into the rootstock tray 8 in a position shifted from the root portion of the rootstock seedling 10 (FIG. 38).
