When the sensor 165 detects the leading end of the scion tray 9 in the conveying direction, the conveyor device 7b intermittently intervenes one row in the conveying direction of each flower pot of the scion tray 9 from that point. Activated.

On the other hand, the conveyor device 66 on the stock line 1 side
Operates intermittently in the same manner as the conveyer device 76 on the scion line 2 side, but the operation interval is the same as the feed interval on the scion line 2 side, and intermittently operates one line at a time in the conveying direction of the flowerpot. 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 in the above configuration will be described below when the conveyor device 6b of the stock line 1 operates in the first feed 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 containing 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, before the respective seedling trays 8 and 9 reach the respective seedling producing devices 19 and 20 in both the lines 1 and 2, the grafting device 3 uses the tray positioning devices 161 and 161 on the line. Of the seedling trays 8 and 9 in the row direction of the seedling trays 8 and 9 toward the respective seedling producing apparatuses 19 and 20. Conveyed. At this time, the adhesive application device 18 is in a standby state, the base 70a is raised, the bracket 74a is retracted, and the nozzle frame member 131 is retracted and raised, The nozzle frame member 131 does not interfere with the rootstock 10.

At this time, on the stock line 1 and the scion line 2, the stock trays 8 and the scion trays 9 of the stock tray 9 aligned in the width direction by the tray positioning devices 161 and 161. , The seedling 11 is a rootstock guiding device 121a,

Guided by a and 122b, the rootstock seedlings 10 and the scionling seedlings 11 in each row are adjusted in the width direction of the tray to an appropriate posture at the time of the rootstock clamping operation and the operation of the scionging clamp operation in the next process.

At this time, the rootstock seedling 10 and the earling seedling 11 before entering the rootstock guiding device 121a and the scion 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 producing apparatus 1 in 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 from which the spikes 10a are preliminarily cut 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.

The trays 8 and 9 positioned in the width direction as described above are placed in 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 the two sensors 165 and 165 are shifted from each other, the conveyor 6b which has been detected first is used.
(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 trays 8 and 9, the stock 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 distal ends of 1a to 32b are clamped by the distal end clamp device 30.

At this time, the first and second clamp plate devices 27 and 28 are separately operated, and first, the second
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.

Next, the stock 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 stock cutting device 23 is not in use, the raising and lowering rod 103 is moved upward as shown by the chain line in FIGS. 6, 7 and 16, and the first cutting blade 104 located on the upper side is moved. Is the clamp operating device 5 of the scion clamp device 24.
1a and 51b. Further, the second cutting blade 105 is rotated in the lateral direction.

When cutting the grafted portion of the rootstock 10, 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, it is raised again to the above-mentioned height and put on standby.

At this time, by rotating the second cutting blade 105 to the lower side of the rootstock clamp plate device 26, the first cutting blade 104 cuts the tip of the rootstock seedling 10 and the rootstock seedling 10 Is performed to create a rootstock for root graft grafting. The root root grafting action of this rooting graft rootstock will be described later.

On the other hand, the scion creating device 20 operates in synchronism with the rootstock creating device 19, and
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, the scion seedlings 11 located below the scion clamping device 24 are guided to the clamp position by the guide pieces 122a and 122b of each pair of the scion guiding device 121b. In the clamp portions 37a and 37b of each clamp plate of the clamp plate device 46,
It is clamped without deviating from this.

If the clamping interval of each clamp plate device is narrower than the thickness of the hypocotyl of each of the seedlings 10 and 11 during the clamping operation of each of the rootstock seedling 10 and the scionling seedling 11, the hypocotyl is crushed. Therefore, the clamp interval width of each clamp plate can be changed for each tray, each seedling rod, and each seedling type. The adjustment of the clamp interval width is performed by each of the clamp plate devices 27 and 2.
8, 47, 48 clamp actuators 33a, 33b, 5
This is performed by changing the length of protrusion of the stopper screw 208 with respect to each base in 1a and 51b.

At this time, also in the tip clamping devices 30 and 41 for clamping the tip portions of the clamp plate devices 27, 28, 47 and 48, the stopper screw 208a is similarly adjusted to adjust the clamp interval width. .

The cutting device 2 in the scion making device 20 described above.
The cutting of the scion seedling 11 by 5 is performed by a scion cutting blade 65 having a two-stage blade configuration, as shown in (a), (b) and (c) of FIGS. The hypocotyl is on the root side and on the plate side.
By 5b, the plate side is cut later with a time difference. Thereby, even when the germination position of the scion seedling 11 is deviated from each clamping position of the clamp plate device, the hypocotyl of the scion seedling cut at the root side by the first blade 65a is clamped to the clamping part. The shape follows the axis, and in this state, it is cut again by the second blade 65b, and the cut surface of the hypocotyl becomes perpendicular to the clamp axis. At this time, the cutting action is performed even if the embryo oil is inclined in any direction as long as it is within the range of the interval between the two blades 65a and 65b having the two-stage blade configuration.

When the scion seedling 11 is cut by the above operation, the scion clamping plate device 46 of the scion clamping device 24 is maintained in the clamped state by the clamping device 41, as shown in FIG. It moves in parallel to the first side by the operation of the moving device 58, and is positioned and stopped immediately above the rootstock clamp plate device 26 which is clamping the rootstock 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.

Next, the elevating device 5 of the scion 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. At this time, the cut surfaces of the seedlings 11 are perpendicular to the hypocotyl due to the cutting action, so that the cut surfaces of both seedlings are in close contact with each other.

The parallel movement and the lowering operation of the scion clamp device 24 are performed by a moving device 58 and a lifting device 57, respectively.
The positioning is performed by a positioning means (not particularly shown) attached to. At this time, as shown in FIG. 16, the clamp device 41 of the scion clamp device 24 is
Are engaged and positioned.

In this state, a pair of first (upper) clamp pieces 38 of the distal end clamp device 30 of the stock clamp device 22 are set.
a and 38b are unclamped and then a pair of clamp plates 31a and 31b of a first (upper) clamp plate device 27 of the base clamp plate device 26 are unclamped, and the first clamp plate device 27 is connected to the stock line. Evacuate to the side of 1.

At the same time, the second (lower) clamp piece of the tip clamp device 41 of the scion clamp device 24 is unclamped, and then the second clamp plate device 46 of the scion clamp plate device 46 is unclamped.
(Lower side) The pair of clamp plates 50a and 50b of the clamp plate device 48 are unclamped and retracted to the side of the stock line 1 as in the case of the stock.

[0094] Thus, the rootstock seedling 1 in contact with the cut end surface
0 and the hogi seedling 11 are the second of the rootstock clamp plate device 26.
The two seedlings 10 are clamped by 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. , 11 have a gap S (FIG. 27) covering two clamp plates.

In the above operation, the rootstock seedling 10 and the hogi seedling 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 application device 1
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.

Therefore, in a state where the two seedlings are in contact with each other, as shown in FIG. 33, first, the hardener spray nozzle 85 of the adhesive application device 18 is lowered, and the entire adhesive application device 18 is advanced to move both the seedlings. The nozzle 85
The sap b is blown and removed by blowing out the air a.

Then, after raising the hardening agent spray nozzle 85, as shown in FIG. 27, the nozzle frame member 131 of the adhesive applying device 18 is lowered to face the contact portion of both seedlings. The adhesive c is discharged close to the contact portions of both seedlings, and applied in a dumpling shape to the contact portions. At this time, the holding plate 143 holding the tape-shaped mesh member 88 along the tip of the nozzle hole 133 of the adhesive coating device 18 is supported, and the support frame 215 supporting this is retracted by the cylinder device 216. Thus, the mesh member 88 is in contact with the tip of the nozzle hole 133 of the nozzle piece 134 by the holding plate 143 as shown in FIG.

Therefore, the adhesive at this time penetrates the mesh member 88 interposed at the tip of the nozzle 76, and the two seedlings 10, 11
Is supplied to the contact portion. Then, the nozzle frame member 131 rises while retreating, but retreats, and slightly retreats from the nozzle frame member 131 to the state shown in FIG.
, And the curing agent d is sprayed together with air to accelerate the curing of the adhesive. An instant adhesive is used as 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, blow 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. After the end of the adhesive application operation, the hardener spray nozzle 85 is raised together with the base 70a.

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

The winding operation of the mesh member 88 will be described below. First, the function of pushing the holding plate 143 forward by the cylinder device 216 and holding the mesh member 88 is released.
Next, the nozzle frame member 131 is connected to the cylinder device 13.
2, 132, the mesh member 88 and the nozzle piece 13
4 is completely separated. Then, simultaneously with retracting the tension stopper 140b, the winding motor 140 is driven to start winding the mesh member 88.

When the mesh member 88 is wound up by a predetermined amount by the counting of the encoder 142, the nozzle frame member 13
1 is brought forward, the tip of the nozzle hole 133 is lightly brought into contact with the mesh member 88, and the adhesive remaining on the tip surface of the nozzle hole 133 is transferred to the mesh member 88 by the mesh member 88 which is being wound and moved. Cleaning. After the predetermined amount of cleaning is completed, the tension stopper 140b is advanced and the winding motor 140 is stopped, and the holding plate 143 is retracted while the mesh member 88 is maintained in a certain tension, so that the mesh member 88 is moved to the nozzle. Frame member 1
31 is pressed to the tip surface of each nozzle hole 133 and brought into contact therewith. The above operation is performed when the adhesive attached to the tip of the nozzle hole 133 starts to harden, so that the tip of the nozzle hole 133 can be cleaned.

As described above, at the time of winding the mesh member 88, the mesh member 88 is wound in a state of being separated from the holding plate 143 and the nozzle hole 133, and can be wound without resistance. Further, the tip end surface of the nozzle hole 133 does not wear because the mesh member 88 does not slide on the tip surface except for the cleaning operation.

After the application of the adhesive and the curing thereof, the remaining clamp plate devices 28 and 47 of the clamp plate devices 26 and 48 on the rootstock side and the splint side are unclamped and the sides of the rootstock line 1 are removed. 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 the unclamping operation after the completion of the bonding, the defective bonding seedling removing device 112
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, poorly grafted seedlings caused by poor adhesion or absence of rootstock remaining between the plates can be removed by 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, every time the adhesive is discharged from the nozzle hole 133 of the nozzle frame member 131, the mesh member 88 is driven by the motor 1 of the mesh member winding device 139.
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.

If no signal is sent from the encoder 142 even if the motor 140 is operated for a certain period of time or longer, for example, if the mesh member 88 is cut off or the mesh member 88 is exhausted, the motor 140 is stopped. 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 moisture, the adhesive is easily cured when the adhesive is applied to the joint of the seedlings through the mesh member 88. Is sprayed with a desiccant while it is wound around the bobbin 141 so that it does not absorb moisture.

Next, with reference to FIGS. 17, 36, 37 and 38, a root grafting method using the grafting device having the above-described configuration and operating the conveyor device 6b in the root line 1 in the second feed mode will be described. I will 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 operation, the stock 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.

Thus, the root side of the row of rootstock seedlings 10 clamped by the rootstock clamping device is cut off. 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.

When the grafting has been completed, the root 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).

In this state, both clamp plate devices 26,
At the same time as unclamping 46, the conveyor device 6b of the stock line 1 is lowered to a normal position, and then is run until the next stock is at a predetermined position. The running length at this time is set to a length obtained by adding or subtracting the length shifted at the time of cutting with respect to the implantation pitch of the rootstock seedlings 10, and the rootstock seedlings 10 in the next row are placed directly below the rootstock clamping device 22. Make it go.

In this root cutting grafting method, as shown by a chain line in FIG. 36, by cutting the second cutting blade 105, the root cutting end can be cut with an inclination, and cutting can be performed well. it can.

In the above embodiment, the clamp actuating devices 33a, 33b, 51a, 51b of the clamp plate devices 27, 28, 47, 48 of the stock and scion clamp plate devices 26, 46, respectively, Clamp actuating device 40 of each tip clamp device 30, 41 for scion
As an example of the clamp interval adjusting means for adjusting the respective clamp widths of a, 40b, 51a, and 51b, stopper members 208 and 208a each having a tip abutting on a base are used for one member that performs a clamp operation. However, the clamp interval adjusting means is not limited to this stopper screw mechanism, and other embodiments will be described below with reference to FIGS. FIG. 1 shows another embodiment.

An adhesive tank 81 in the adhesive application device 18 shown in FIG. 26 is, for example, as shown in FIG. 44, and is an adhesive tank in which an adhesive made of a soft material is put in a pressure tank 233. A pressure bag 234 is put into the pressure tank 233, and pressurized air flows from an air tube 234a into the pressure tank 233. The pressure is applied to the pressure-sensitive adhesive bag 234 from outside, and the adhesive is pushed out from the pressure bag.

In such an adhesive tank 81, the adhesive can be pressurized without touching the air, and the curing of the adhesive due to the contact with the air can be prevented. By using a transparent material for the pressurized tank 233 and the adhesive bag 234, the remaining amount of the adhesive in the bag can be grasped from the outside.

It is to be noted that the adhesive bag 234 is made transparent in order to know the remaining amount of the contact agent in the bag, and the remaining amount can be easily grasped by taking it out of the pressurized tank 233. The amount of the adhesive is measured by measuring the weight of the pressurized tank 233 itself with the scale 236. Even when the adhesive is used up due to some mistake, there is no possibility that air is mixed into the adhesive supply tube 235. When the adhesive is changed, it can be replaced smoothly.
