Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grafted seedling production apparatus and a grafted seedling production method.

[0002]

2. Description of the Related Art As a device for continuously producing a large amount of grafted seedlings, the applicant of the present invention has previously disclosed Japanese Patent Laid-Open No. 6-141.
The one disclosed in Japanese Patent No. 679 (Japanese Patent Application No. 4-154305) was proposed. In the grafted seedling production apparatus according to this prior application, a root line and a scion line are provided so as to be opposed to each other in their moving directions, and the upper and lower two-stage clamp plates are separately clamped to the root line. A clamp device for wood is provided so as to be movable in a direction crossing the stock line, and a positioning clamp device for clamping this, and a stock cutting device for cutting the stock in a clamped state along the upper surface of the clamp plate. A rootstock making device consisting of is provided, and on the scion line, with substantially the same configuration as the above rootstock making device,
In addition, a scion cutting device consisting of a scion cutting device that cuts scions along the lower surface of the clamp plate is provided, and the clamp plate of this scion forming device is moved up and down and the scoop cutting position and the clamp position of the rootstock creating device. It has a structure that can be turned over.

[0003]

In the above-mentioned conventional grafted seedling production apparatus, since the tip of the rootstock seedling was temporarily cut manually, this temporary cutting requires considerable time and labor. Was there. Moreover, the seedlings that had been grafted were left to stand beside the device for a while, so that there were seedlings that shrank and could not survive, resulting in poor yield.

Further, by raising and lowering the table on the side of the spikes to prevent interference and to reduce the installation area of the apparatus, the cycle time etc. did not increase and it was structurally impossible to improve the time efficiency. In addition, it was moved to the rootstock seedling by rotating the spikelet seedling making device (spindle unit), but considering the vibration of the seedling, it is difficult to rotate at high speed and it is difficult to improve the cycle time. Met. In addition, due to the rotary motion, it is dangerous because it is necessary to pay attention to safety in the rotation range.

Further, the tip end of the clamp plate on the side of the bush is loosened and cannot be clamped due to mechanical vibration or the like, and it slips through the upper part at the time of positioning and cannot obtain a crimping force.

Further, when the scion clamp plate descends onto the root clamp plate, not only is the leaf of the seedling that has finished grafting caught between the clamp plates, but it is also damaged when the clamp plate is retracted. There was a case where the grafted part was removed. In addition, in the case of seedlings that failed to bond at the end of grafting or seedlings without rootstocks from the beginning,
In some cases, the unfixed scion seedlings had knocked down the seedling-end seedlings.

Further, with respect to seedlings having poor sowing position accuracy and guided and fixed from a distance from the center of the clamp, the seedlings may be cut or crushed during the induction. Moreover, the height of the grafting positions of the seedlings with uneven growth of scion also varied, and the growth of the seedlings in the tray was uneven.

Also, since the instant adhesive reacts with water to coagulate, the adhesive remaining at the tip of the adhesive nozzle gradually begins to coagulate and begins to rise at the nozzle tip, pushing the hypocotyl at the time of adhering and shifting the position. Will cause the
In order to prevent this, maintenance such as washing was necessary frequently.

Further, since the current nursery tray is made of a soft material and is lightweight, it is inconvenient to carry it and install it in a grafting device. Since it is carried on the receiving tray and used for transportation, it is necessary to remove the seedling raising tray from the receiving tray if it is not placed on the line of the grafting device while being carried on the receiving tray. In addition, since there was a space between the current seedling raising tray and receiving tray, there was backlash,
It was difficult to accurately position the seedling raising tray.

Further, by inserting the clamp plate so as to cross the grafting line, the positional deviation of the seedlings in the line direction can be corrected, but the lateral direction is limited by the guiding angle and the guiding range of the plate. .

Further, if the grafting failure is left as it is and the operation is continued, the machine is damaged and the yield is lowered. In addition, it takes a lot of cost and labor for mass monitoring, such as continuous operation, when multiple people monitor. In addition, when there is a difference in the growth of scion seedlings, there is a problem that the length after cutting becomes different.

The present invention has been conceived in view of the above, and it is possible to automatically perform temporary cutting of rootstock seedlings, improve grafting efficiency, and improve grafting yield. The grafted seedling production device and grafted seedling production are designed to solve the above-mentioned conventional problems, such as making it possible to create both spikes and rootstocks at the same time without increasing the installation area, and shortening the cycle time. It is intended to provide a method.

The protection plate 127 has both ends rotatably supported by the bracket 126, and the protection plate 127. A rotation device 128 that rotates the protection plate 127 downward from a substantially horizontal state, a base 129 that supports the bracket 126, and a moving device 130 that reciprocates the base 129 in the transport direction of the stock line 1. It consists of The seedling 1 is attached to the tip of the protective plate 127.
The rake 131 is placed at a position equally spaced from the lateral pitch of 0 and 11.
Is protruding. Note that each rake 131 is shown in FIG.
As shown in (a) and (b), the seedlings 10 and 11 are arranged so as to oppose to the pull-out direction side of the clamp plate when unclamping.

The operation of the above configuration will be described below.
The rootstock seedling 10 and the scion seedling 11 are grown to a predetermined size in a greenhouse or the like in the rootstock seedling tray 8 and the scion seedling tray 9, respectively. At this time, both seedlings 10 and 11 are regularly grown in a grid shape with the same intervals. The trays 8 and 9 thus raised are stored in receiving trays 12 and 13, respectively, and supplied to the upstream side of the lines 1 and 2.

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

At this time, in the lines 1 and 2, before the seedling trays 8 and 9 reach the seedling producing devices 19 and 20, respectively, in the grafting device 3, the tray aligning devices 115 and 115 are used on the lines. After the positioning in the width direction of the seedlings is performed and the positioning in the transport direction is performed by the sensors 119 and 119, the seedling trays 8 and 9 are directed toward the seedling production devices 19 and 20 at a pitch of one row in the transport direction. Be transported.

Next, each seedling producing device 1 on both lines 1 and 2
The operation at 9 and 20 will be described. The seedling trays 8 and 9 conveyed at the feed pitch are the seedling producing devices 1
The seedling production time is stopped at 9 and 20, and this stop time is the feed pitch interval. The predetermined seedling rows on the seedling trays 8 and 9 of the lines 1 and 2 are the clamping devices 2 of the grafting device 3.
The transportation of the lines 1 and 2 is stopped in a state where it has reached just below 2, 24, and the grafting work 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 115, 115 on each line of the grafting device 3 in a synchronized state. Then, while passing therethrough, the receiving trays 12 and 13 are positioned by biasing rollers 117, and the trays 8 and 9 are positioned at predetermined positions in the width direction by the pushing plate 118.

Each of the trays 8 and 9 positioned in the width direction as described above has the tray positioning devices 115 and 115.
After being conveyed further downstream, the sensors 119 and 119 detect the subsequent trays 8 and 9. Both sensors 119,
If the tray detection by 119 is simultaneous, from that point, both the first conveyors 6b and 7b on the rootstock side and the scion side synchronously start the transfer of the flowerpots of the trays 8 and 9 by one row pitch. To do.

At this time, if the detections of both sensors 119 and 119 are deviated, the conveyor 6b of the one detected first is detected.
When (7b) stops on the spot and is delayed, when the other sensor detects the tray, both conveyors 6b and 7b are intermittently operated in the same manner as above. In this way, the trays 8 and 9 on the rootstock side and the scion side are synchronously moved intermittently one row at a time, and each conveyor 6b, 7 of the grafting device 3 is moved.
It is transported on b.

Of the above trays 8 and 9, the root tray 8
The rootstock seedling 10 obtained by cutting the tips 10a of
Then, it is clamped by the root clamp device 22, and then cut by the cutting device 23 at a position along the upper surface of the root clamp device 22. At this time, the root clamp device 2
Each of the first and second clamp devices 27 and 28 of the second root clamp plate device 26 is inserted between the root seedlings 10 in the tray 8 in the expanded state, and then the clamp operation is performed, whereby the respective clamp plates 31a. ~ 32b clamp 37
The rootstock seedling 10 is clamped to a and 37b. Then, in this state, the tips of the clamp plates 31a to 32d are clamped by the 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.
The clamp plate device 28 may be used for clamping, and then the first clamp plate device 27 located on the upper side. As a result, the curved rootstock seedling 10 can be clamped without difficulty.

On the other hand, the scion producing device 20 operates in synchronization with the rootstock producing device 19, and the scion seedling 11 on the scion tray 9 is used.
Is clamped by the scion clamping device 24, and then the cutting device 23 is placed at a position along the lower surface of the scion clamping device 24.
Is cut at

At this time, as shown in FIGS. 25 (a) and 25 (b), the clamping operation of the scion clamp plate device 46 is stopped midway to loosely clamp the scion seedling 11, and in this state, the cutting device is cut. The cutting blade 65 of 23 is slightly lowered and the scion seedling 1
1 is cut a little longer, and then, as shown in FIGS. 26 (a) and 26 (b), after the clamping operation is completed and the above-cut long cuttings 11 are clamped again, the cutting blade 65 is attached to the clamp plate. Lift to a position along the bottom surface and cut again. By cutting by the two-step induction as described above, when the scion seedling 11 is grown off the center of the flowerpot as shown in FIG. 25 (b), it can be cut without being damaged. Further, according to this method, since the first stage cutting is not yet firmly clamped, each scion seedling 11 has its leaf portion clamped by gravity as shown in FIGS. 26 (a) and 26 (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 above 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 the scion seedling 11 is cut by the above-mentioned 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 transfer device 58 is moved in parallel to the first side, and the positioning is stopped immediately above the rootstock clamp plate device 26 in a state where the tips of the rootstock seedlings 10 have been cut off. Then, the raising / lowering device 57 of the scion clamp device 24 is operated to lower the scion clamp plate device 46, and the cut end of the scion seedling 11 clamped by the scion clamp plate device 46 is the root clamp plate device 26.
The cut end of the rootstock seedling 10 clamped at is abutted.

The parallel movement and the lowering operation of the above-mentioned scion clamping 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, the clamp device 41 of the scion clamp device 24 is engaged and positioned with the rootstock clamp device 30.

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 rate device 27 of the stock clamp plate device 26 is 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 piece of the clamp device 41 of the spike clamp device 24 is unclamped, and then a pair of second (lower) clamp plate devices 48 of the spike clamp plate device 46 are 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.

As a result, the rootstock seedling 1 with which the cut end surface is abutted
0 and sapling 11 are the second of the root 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 (FIGS. 18 and 19) extending over two clamp rates.

Next, the adhesive applying device 18 is moved to the stock making device 19 side, and as shown in FIG. 18, the adhesive nozzle is placed in the gap S between the portions clamped by the clamp plate devices 28 and 47. 76 is inserted, the tip of this is made to oppose the contact part of both seedlings 10 and 11, an adhesive is discharged, and this is applied in the shape of a dumpling at the contact.

At this time, the adhesive passes through the mesh member 88 interposed at the tip of the nozzle 76 and is supplied to the joint between the seedlings 10, 11. Then, the nozzle 76 retreats, and slightly later than this, as shown in FIG. 19, the curing agent is sprayed from the curing agent spray nozzle 85 to accelerate the curing of the adhesive.

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. This can prevent clogging of the adhesive nozzle 76 due to the curing of the adhesive.

After applying the adhesive and curing the same, 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 poor adhesion in one row of seedlings, the scion seedlings 11 fall and lean against the clamp plate side to be unclamped. When the clamp plate is pulled out to the side of the stock line 1 again, the fallen seedlings are hooked at the clamps and dragged together, thereby knocking down other seedlings that have been grafted well. This is prevented by the graft protection device 125.

That is, the protection plate 127 of the graft protection device 125 is operated as shown in FIG.
As shown in (a), the portion of the rake 131 is inserted between the grafted seedlings 11. As a result, the unbonded spikes 11 are not caught by the rake 131 and dragged by the clamp plate.

Further, when the scion clamp plate device 46 descends to the position of the root clamp plate device 26,
As shown in FIG. 24 (b), the protection plate 127 is moved to the seedling side on the grafting end side, and is rotated downward to press the leaf of the seedling on the grafting end side, and the scoop clamp plate device 46 is lowered. Contact with.

As a result of the above-described operation of each section, each rootstock seedling 9 in the rootstock tray 8 on the rootstock line 2 is horizontally aligned with each rootstock seedling 8 in the rootstock tray 8 on the rootstock line 1. Grafted one by one. And the conveyor 6 of both lines 1 and 2 of the grafting device 3
b and 7b are intermittently moved at a pitch of one row in synchronization with the grafting operation.

The rootstock tray 8 which has been grafted as described above is conveyed to the end of the rootstock line 1 together with the receiving tray 12, and is sequentially stored from here to the multi-tiered rack 102 in the temporary curing apparatus 5, and all the tiers. When the tray is stored in, move it to the main room. In the temporary curing device 5, the humidifier 107 humidifies the tray so that the humidity is constant, and the trays are stored in the multi-stage rack 102 for a relatively long time.

Different embodiments of the above-mentioned device of the present invention will be described below. 27 to 30 show another embodiment for performing two-stage induction clamping of the respective clamp plate devices 47 and 48 of the scion clamp plate device 46 of the scion clamp device 24. In this description, the first clamp plate device 47 located on the upper side is shown. Two spacer pieces inserted into the base 52a of the first clamp plate device 47 between both movable pieces 135a and 135b of the first clamp actuation device 51 and both sides of the clamp actuation part 136 in which the cylinder device is installed. A spacer 138 having 137a and 137b is attached through a vertical movement device 139 composed of a rodless cylinder or the like.

FIGS. 28 (a), (b), and (c) show the operation of the above-described two-stage induction clamp device, in which the spacer 138 is lowered at the start of clamping to move both movable pieces 135a, 13a.
Spacer pieces 137a and 137b are inserted between 5b and both sides of the clamp operating portion 136 (FIG. 28 (a)). By operating the clamp in this state, the spacer piece 1
37a, 137b and the clamp actuator 51,
The intermediate stop position is provided at an interval corresponding to the thickness of the spacer piece (FIG. 28 (b)). The first cutting of the scion seedlings 11 is performed in this state, and the scion seedlings 11 fall until the leaf portions are caught by the clamp plates 49a and 49b.

Then, the spacer 138 is raised to move the spacer portions 137a and 137b into the movable pieces 135a and 135.
It is pulled out from between b and the clamp operating portion 136, and the clamp operation is performed again (FIG. 28 (c)). As a result, 1 sapling
1 is clamped in a state where the heights up to the leaves are aligned, and in this state, the second cutting is performed along the lower surface of the lower clamp plate.

29 and 30 show still another embodiment of the two-stage clamp mechanism. This is the clamp actuator 5

The operation of this embodiment will be described below. When the clamp cylinder 142 is in the open state, the pneumatic bubble 144 is energized to the solenoid A and is in the unclamp position (a) (FIG. 30 (a)). At this time, only the magnetic sensor 141a on one side catches magnetism.
When the clamp is started by the clamp command, the solenoid B is energized to reach the clamp position (b), and the clamp cylinder 143 starts the shortening movement (FIG. 30 (b)). As a result, both clamp plates 49a and 49b are clamped, and in conjunction with this, the magnet 142 is positioned between the two magnetic sensors 141a and 141b facing each other (FIG. 29).
(B)). In this state, both magnetic sensors 141a, 14
1b catches the magnetism, and in response to the symbol, both solenoids A and B of the pneumatic valve 144 are in the OFF position (C), the air inside the clamp cylinder 143 is released (Fig. 30 (c)), and an intermediate stop is made. It becomes a state (Fig. 29)
(B)).

In this state, the first disconnection is performed, and then the solenoid B of the pneumatic valve 144 is energized by the clamp command again to perform the clamp action (FIG. 30).
(D)), both clamp plates are clamped (FIG. 29 (c)). In this state, the second cutting is performed. After that, both clamp plates 49a and 49b are unclamped again (FIGS. 29A and 30A).

FIGS. 31 to 33 show another example of the adhesive applying device 18, and FIG. 31 is adapted to apply the adhesive indirectly. That is, the root line 1 in advance
To the roller 153 driven by the motor 152 while intermittently applying the adhesive to the tape 150 made of a material such as a paper tape that can be wound up on the outer side of the tape, which is hard to soak the adhesive with the pressure dispenser 151 in accordance with the seedling interval. The tape 150 is wound up, and the tape 150 stands by while straddling the stock line 1. A pinch roll 154 is arranged on the feeding side of the tape 150 to provide tension. The tape 150 is held horizontally by the receiving member 155.

The adhesive applying device 18 is moved up and down by the elevating device 156, and is waited upward by the elevating device 156 when the tray moves on the stock line 1. At the time of adhesion, the adhesive is applied by coming down and advancing by the slide tables 157 and 158 to press the adhesive-applied tape 150 onto the adhering portion of the seedling. After that, it moves backward and rises and stands by. Then, during this standby, the tape 150 is fed while applying the adhesive. Reference numeral 159 is a coma roll for sending the tape 150.

FIG. 32 shows another example of an adhesive applying device for applying adhesive directly. The tip of each adhesive nozzle 76a is fixed to the plate 160, and each adhesive nozzle is attached to this plate 160. 76a is opened. The plate 160 is made of a material to which an adhesive does not easily adhere.
Then, the adhesive application device advances to apply the adhesive with the tip of the nozzle 76a facing the joint of the seedlings clamped by the clamp plate device together with the plate 160.
After that, after retreating to the original position, the scraper 163 of the adhesive stripping device 162 provided so as to straddle the stock line 1 strips the adhesive on the surface of the plate 160 and on the nozzle opening. To do. Adhesive peeling device 16
The second scraper 163 is adapted to be vertically operated by an elevating device 166 on a base 165 which moves laterally by a rodless cylinder 164 with respect to a table 161 which supports the adhesive nozzle 76a.

FIG. 33 shows another example of the tray position adjusting device, in which the receiving trays 12, 13 which have been conveyed through the lines 1 and 2 of the grafting device 3 are stopped by the stoppers 170 (or 170a and 170b). Temporarily fixed, receiving tray 12
When the tray is stopped, the tray fixing jigs 171 and 171 in a skewered shape are slid from both sides of the line by the slide device 173.
(9) is inserted into the bottom side recessed portion to receive trays 12, (1
Hold regardless of 3). After the hold is completed, the stopper 170 (or 170a, 170b) is lowered and the slide cylinders 172, 172 are moved in the line direction. By the slide cylinders 172 and 172, the space between the trays 8 and (9) of both lines 1 and 2 is managed one row at a time, and the positions are surely aligned.

As shown in FIG. 35, a comb-shaped scion guide plate 175 is provided below the clamp rate device of the scion clamp device, and the scoops conveyed to the scion line 2 are provided. Before the seedling 11 is inserted into the clamp plate device, even if the seedling 11 is misaligned so as not to fall within the guide width of the clamp plate, the spikelet seedlings can be inserted into the spike guide plate 175.
It is designed to be preliminarily guided to a predetermined position. 36 (a), (b), and (c) show the above-described guiding state, in which the slanted panicle seedlings 11 are pulled up by the panicle guide plate 175 before the clamp plate device is inserted.

As shown in FIG. 37, the clamp plate of the root clamp device 26 is provided with optical sensors 180a and 180b for monitoring the upstream side and the downstream side of the root line 1, and the optical sensor 180b on the downstream side is provided. The presence / absence of seedlings after grafting is confirmed, and the upstream optical sensor 180a confirms the presence / absence of rootstock seedlings 8 on the line to be grafted next. Further, although not shown, the clamp plate devices 47, 48 of the scion clamping device 46
An optical sensor is embedded in the tip of the clamp plate on the upstream side, and the presence or absence of the next row is checked by this optical sensor when the clamp plate is inserted.

A switch for applying an adhesive can be used when the grafting operation of the next row is performed based on the detection data of each optical sensor. Also, by checking the presence or absence of seedlings on the downstream side of the rootstock line 1, if seedlings in the same row do not continuously exist, it is considered that some grafting error has occurred, and this sensor can be used to detect the malfunction of the device as soon as possible.

In the above embodiment, the rootstock seedling 10 and the scion seedling 11 are used.
At the time of bonding with, in order to hold the bonded seedling at this time, a graft protection device 125 was provided on the downstream side of the bonding work position. As means for protecting the grafted seedling at the time of bonding, other than the above-mentioned embodiment In addition, the following configurations may be adopted.

That is, as shown in FIGS. 38 to 43, above the stock clamp device 22, it operates in conjunction with the operation of the second (lower) clamp plate device 28 of this stock clamp device 22. A protective plate 201 is provided.

This protective plate 201 is located upstream of the stock line 1 of the clamp actuating device 33b for fixing and clamping the second clamp plate device 28 of the stock clamping device 22 via the cylinder device 202 and the arm 203. It is cantilevered on the block 33b 'side. The cylinder device 202 and the arm 203 wrap around so as to avoid the first and second clamp plate devices 27 and 28 from the lower side, and the first (upper) clamp plate device 27.
It is designed to stand vertically on the upper side of. The position of the protective plate 201 in the clamp operating direction is shown in FIG.
As shown in (a) and (b), the unclamped state (see FIG.
3 (a)), it is located above the stock clamp device 26, but in the clamped state (FIG. 43 (b)), it is disengaged from the stock clamp device 26 to the downstream side of the stock line 1. Further, in this state, the cylinder device 202
By extending, as shown in FIG. 44, it is possible to move further downstream. At this time, arm 2
03 is slidably supported by a rod 202a and a guide 202b.

Bracket 2 for supporting the protection plate 201
02 and the arm 203 are on the side of the clamp actuating device 33b and deviate laterally from the moving range of the seedling so that the bracket 202 and the like do not interfere with the seedling.

In this construction, when the rootstock clamping device 26 is inserted between the rootstock seedlings 10, the protection plate 201 becomes integrated with this and is inserted into the upstream side of the grafted seedlings. As a result, even the seedlings that have been grafted, which had been tilting obliquely, will be scraped toward the downstream side by the protective plate 201 (FIG. 43 (a)).

When the root clamp device 26 is clamped, the clamp actuating device 33b clamps the block 33b 'to the downstream side of the protective plate 2 by the clamp operation.
01 moves to the downstream side (FIG. 43 (b)), whereby the leaf portion of the seedling after the grafting is pushed to the downstream side by the protective plate 202.

At this time, the protective plate 201 is located at a position deviated from the upper side of the root clamp device 26 in the clamped state to the downstream side, so that the leaves of the seedlings after grafting do not remain above the root clamp device 26. When the scion seedlings are clamped on the root stock clamp device 26 and the scooping clamp device 24 descends, it is possible to prevent the leaf portion of the seedlings after the grafting from being pinched. When the grafting operation is completed and both clamp plates of the scion clamp plate device 46 are lifted in an open state, the cylinder device 202 is extended to move the protective plate 2.
02 is further moved to the downstream side (FIG. 44). As a result, the clamp device 24 is raised without interfering with the protection plate 201.

Further, as shown in FIGS. 38, 39, 45 and 46, the clamp plate 49 on the upstream side of the first (upper) clamp plate device 47 of the spike clamp device 24.
By arranging the leaf drip prevention plate 204 on the upper surface of a as well, it becomes possible to bond the leaf portions of the rootstock seedlings without interfering with the operation of bonding the rootstock seedling 10 and the rootstock seedlings 11.
FIG. 46 shows such a state, in which the leaf portion of the scion seedling 11 is scraped upward by the leaf dripping prevention plate 204, and the adhesive nozzle 76 is provided between the clamp devices 22 and 24 in the gap S. This will not get in the way when you insert.

FIG. 47 shows another embodiment of the adhesive applying device 18 shown in FIG. Adhesive nozzles 76 for the number of grafted seedlings are fixed to one guide plate 205, and the adhesive is ejected from an adhesive ejection port 205a provided corresponding to each nozzle 76 on this guide plate 205. There is. A tape-shaped mesh member 88 is guided along the front surface of the guide plate 205.

A mesh member feeding device 206 is provided on one side of the guide plate 205, and a mesh member winding device 207 is provided on the other side. 207a is a winding motor. Mesh member feeding device 206
Is a bobbin 208 for feeding the mesh member 88 and the mesh member 8
8 and an encoder 209 for detecting the feeding amount.

The adhesive nozzle 76, as shown in FIG.
It may be attached obliquely to the adhesive discharge port 205a provided in the guide plate 205 'so as to avoid seedlings.
Further, in order to give tension to the mesh member 88 and reduce the contact surface with the mesh member 88, the adhesive discharge port 20
The stopper plate 2 for making the mesh member 88 have a tension between the adhesive discharge ports 205a by making the portion 5a trapezoidal.
You may provide 10.

In such an adhesive applying device 18 ', the mesh member 88 is wound up by the motor 207a of the mesh member winding device 207 by a predetermined amount. At that time, the encoder 209 on the mesh member feeding device 206 side. The feeding amount is counted at, and when the encoder 209 counts a fixed amount, the motor 207a is stopped by the signal.

On the motor 207a side as well, if a signal is not sent from the encoder 209 even if the motor 207a is operated for a certain period of time or more, for example, the mesh member 88 may be cut or the mesh member 88 may be broken.
If it disappears, it will stop and notify you. The encoder 209 can count the total amount of feeding and control the remaining amount of the mesh member 88.

If the mesh member 88 contains such water, the adhesive agent is easily cured when the adhesive agent is applied to the joint portion of the seedling through the mesh member 88. The moisture preventive agent is sprayed while being wound on the bobbin 208 so as not to absorb moisture.

In addition, in the above-described embodiment, FIG. 33 and FIG.
As shown in, an example in which the trays 8 and 9 on the rootstock side and the scion side are synchronously transported on the respective conveyors 6b and 7b while being intermittently moved one row at a time As shown, in the spike producing device 20, the operation of the spike tray 9 is performed immediately after the spike seedlings 11 are separated by the cutting device 25, and the slide cylinder 172 moves the tray 9 for one row or a fixed amount. You may just return it to the upstream side.

As a result, the scion seedlings clamped and separated by the clamp device are separated from the scion seedlings in the next row, and when the scion clamping device 20 moves to the rootstock making device 22 side.

Air may be ejected after the spraying of each.

In this case, as shown in FIG. 53, the curing agent spray nozzle 85 has a double configuration of a curing agent ejection hole 214 and an air ejection hole 215. Then, as shown in FIG. 54, air is blown against the adhesive. This spreads the dumpling-like adhesive thinly around the stem.

Next, as shown in FIG. 55, the curing agent is discharged together with the air. As a result, the curing agent is atomized and sprayed, the adhesive is cured, and the rootstock seedling 10 and the scion seedling 11 are fixed. Finally, after-blowing the air. As a result, the curing agent remaining in the curing agent ejection port 214 is discharged, and the remaining amount in the pipe is adjusted so that the curing agent at the next time is kept at a constant amount.

Further, by the after-blowing of the air, the curing agent existing around the stem is blown off to the downstream side of the stock line and diffused. In order to blow off and diffuse the curing agent, a blower 216 may be provided on the upstream side of the adhesive application device 18 toward the downstream side as shown in FIG.
