Is integrally formed so that the cell-shaped pots 5 are arranged in a grid pattern in the vertical and horizontal directions (6 in the horizontal direction, 12 in the vertical direction in the embodiment). The seedling of tree 6 and the seedling of scion 7 are raised in advance at locations not shown.

The grafting and seedling production apparatus 1 of the present invention includes a rootstock 6
Transporting means 8 and 9 such as a belt conveyor for intermittently moving the tray 4 of No. 7 and the tray 4 of the scion 7 in the directions A and B, respectively, are arranged in parallel. Discharge conveyors 10 and 11 that convey the tray 4 in a direction perpendicular to the side ends are arranged adjacent to the side ends (see FIG. 1).

As shown in FIG. 1, in order to form a cutting surface for joining at a predetermined height position of the stem 6a of the rootstock 6, a base is formed in the middle of the conveying means 8 of the tray 4 of the rootstock 6. While the wood cutter mechanism unit 12 is provided, a pre-cutting mechanism unit 13 that cuts the upper part of the cutting surface in advance is provided on the upstream side in the conveying direction, and the upper part of the stem is formed to form a cutting surface for later joining. It is configured so that it can be smoothly discharged.

The pre-cutting mechanism 13 shown in FIGS.
The tray 15 includes a receiving plate 16 that extends upstream in the transport direction of the tray 4 and that is disposed so as to cross over the transporting means 8 and a cutter means 21 described below. It is movably supported and a drive actuator 27 is attached to the pivot 15. The installation height of the receiving plate 16 is set to be substantially equal to the preliminary cutting height of the rootstock 6, and the stem 6a of the rootstock 6 intermittently conveyed in the direction of the arrow A is fitted into the receiving board 16. The guide groove 17 is formed, and the stem 6a temporarily stopped at the position of the guide groove 17 is attached to the holding bar 19 having a hook shape in a plan view which is substantially horizontally rotated by a rotary actuator 18 provided on the lower surface of the receiving plate 16. It is held and held in position.

3 and a rotary blade 22 that is driven thereby, and a pinion gear 25 that rotates from a drive motor 23 via a transmission gear mechanism 24 meshes with a rack portion formed on the side surface of the horizontal shaft 20 to move the cutter means 21 at the same time. Rotary blade 22
When is rotated, the upper end side of the stem 6a is cut and dropped on the receiving plate 16.

A discharge conveyor is disposed behind the receiving plate 16 (downstream side of the conveyance) so as to cross the upper side of the conveying means 8 in parallel with the pivot 15, and the upper surface is moved toward the waste box 28 by a motor (not shown). 26 is arranged, and the receiving plate 16 is centered on the pivot 15 by the drive actuator 27.
When the solid line state is rotated to the two-dot chain line state, the unnecessary stems 6a that have been cut off fall from the receiving plate 16 to the discharge conveyor 26 and are then discharged to the waste box 28. As a result, the upper ends of the stems 6a of the horizontal rows 6 of the rootstocks 6 on the tray 4 are cut off all at once, and the inverted backing plate 16 is returned to the state shown by the solid line in FIG. The transporting means 8 is driven intermittently so as to be sent to a location.

The root cutter mechanism 12 is shown in FIGS.
The plurality of boat-shaped guide plates 30 for guiding the left and right sides of the stems 6a of the rootstocks 6 arranged in a row on the tray 4 and for positioning the vicinity of the roots of the stems 6a are shown in FIG. An actuator 32 with a holding bar 31, a cutter means 33 for cutting the stalk 6a into a predetermined shape to form a cut surface, and a discharge conveyor 35 for discarding the unnecessary stalk 6a in a waste box 34 (drive means: (Not shown).

As shown in FIGS. 11 and 12, the hull form guide plates 30 are arranged in a horizontal row with a gap 29 through which each stem 6a can pass, and are attached to the front end of the upper surface of each hull form guide plate 30. 36 is fixed to the lateral support rod 37, and the support rod 38 attached to the rear end of the upper surface of each boat-shaped guide plate 30 is the inclined guide plate 39.
The horizontal support rod 37 and the guide plate 39 are fixed to a frame (not shown). The inclined guide plate 39 has a guide groove 4 which is open at one end and which guides the stem 6a of the rootstock 6 up and down.
The notch 0 is formed.

On the upper surface of each boat-shaped guide plate 30, each stem 6a
Two actuators 32 each having a holding bar 31 for positioning the vicinity of the root part of the ship are attached, and the holding bar 31 horizontally rotated from the backward position to the front lateral direction by the operation of the actuators 32 is used for the left and right vessels. Mold guide plate 3
The rear end surface of the stalk 6a that has stopped advancing in the gap 29 between the side surfaces of 0 is brought into contact with and positioned, and then the other actuator 32 is operated to horizontally rotate the holding bar 31 facing forward in the rear lateral direction, As shown by the solid line in FIG. 11, the holding bar 3
It is sandwiched by 1, 31 and held in position.

The front end side (transport upstream side) of the inclined guide plate 39 is extended downward, and the cutter means 33 having the following construction is provided below the inclined surface. That is, a case 42 is movably mounted on a guide support shaft 41 extending in a direction orthogonal to the transport direction (arrow A direction), and a pinion gear that is driven by a motor 43 attached to the case and that rotates via a built-in transmission mechanism is provided. The case 42 engages with a rack formed on the side surface of the guide support shaft 41 so that the case 42 can reciprocate along the guide support shaft 41. The case 42 has a cutting blade 44 substantially parallel to the lower inclined surface of the inclined guide plate 39. A plurality of stalks 6a that are attached in parallel and are arranged in a horizontal row are cut in a sloping manner (at a lower position on the upstream side of conveyance and at a higher position on the downstream side of conveyance). The cutter means 33 provided in the rootstock cutter mechanism section 12 may be a rotary blade similar to the cutter means 21 provided in the preliminary cutting mechanism section 13.

The clamping hands 45a and 45b are for clamping the upper side of the stem 6a to be cut and discarded.
A pair of operating shafts 46a, 46b to which the roots of the gripping hands 45a, 45b are fixed at each of the stems 6a.
Are slidably supported by the left and right frames 54, 54 via sliding bearings (see FIG. 9). One ends of the pair of actuating shafts 46a and 46b and both ends of a swinging link 47 that is swingable about a central axis 49 are pivotally mounted via a connecting link 48 to expand and contract the swinging link 47. The pair of gripping hands 45a, 45b is swung by the moving actuator 50 to move one operating shaft 46a in the direction of arrow C and the other operating shaft 46b in the direction of arrow D.
The interval between the tip holding portions 51, 51 is narrowed to hold the stem 6a. On the contrary, when the one operating shaft 46a is moved in the arrow E direction and the other operating shaft 46b is moved in the arrow F direction, the gap between the pair of holding portions 51, 51 is widened.

The arm portions 52 of the both holding hands 45a and 45b may be formed of leaf springs that are easily elastically deformed,
If the tip holding portion 51 is made of soft rubber or synthetic resin sponge material that is easily elastically deformed, the position of the holding stem 6a is slightly displaced in the left-right direction (direction orthogonal to the transport direction A). Also the pair of clamping hands 45a, 45
The stem 6a can be firmly clamped by b.

Then, each pair of clamping hands 45a, 45
After the lower part of the stalk 6a clamped by b is cut by the cutter means 33, the rotary actuator 53 is operated to lift the clamping hands 45a, 45b together with the side frames 54, 54 and the operating shafts 46a, 46b. , Figure 1
When the actuator 50 is driven to widen the interval between the holding hands 45a and 45b in a state where the posture is reversed to the position indicated by the two-dot chain line 0, the unnecessary stem 6a that has been cut off falls onto the discharge conveyor 35 and the waste box 34 It is discharged to. As a result, the upper ends of the stems 6a of the rootstocks 6 arranged in a line on the tray 4 are cut off all at once, and the gripping hands 45 are turned upside down.
After a and 45b have returned to the solid line state of FIG. 10, the actuator 32 is used to feed the rootstock 6 in the rear row to the 40 guide grooves.
Is reversely operated to return the holding bar 31 to the posture substantially parallel to the carrying direction, and the carrying means 8 is intermittently driven.

Next, the construction of the scion cutting mechanism section 2 will be described with reference to FIGS. 1, 2, and 15 to 20.
The gate-shaped frame 55 in the spike-cutting mechanism unit 2 is arranged so as to straddle the rear ends (lower ends of the transport downstream) of both the transport means 9 for the spikes 7 and the transport means 8 for the rootstock 6. On the upper side of the transport means 9 of the gate-shaped frame 55, as in the rootstock cutter mechanism section 12, right and left near the roots of the stems 7a of the spikes 7 arranged in a horizontal row on the tray 4. A plurality of boat-shaped guide plates 30 for guiding the ship are arranged. Each hull-shaped guide plate 30 is made to hold its position by the structure of the support rods 36, 38, the lateral support rod 37, etc. as in the above.

Further, an actuator 32 with a holding bar 31 for positioning the vicinity of the root portion of each stem 7a in the scion 7, and a cutter means 33 for cutting the stem 7a into a predetermined shape to form a cut surface. Since the configuration is the same as that described above, the reference numerals of the components are the same, and the description thereof is omitted. What is needed in the scion cutting mechanism section 2 is the tip side of the stem 7a, and the unnecessary root part of the scion 7 is transferred to the discharge conveyor 11 together with the tray 4 after the cutting work described later.

In the scion cutting mechanism section 2 of this embodiment,
The operation of cutting the scions 7 on the tray 4 one by one and conveying the cut stems 7a on the upper side (parts with cotyledons) one by one toward the grafting mechanism section 3 described later is repeated. The mechanical unit 3 also executes the grafting operation one by one. In addition, the side-by-side cuttings before cutting are not disturbed during lateral transportation of the cuttings, and the grafted seedlings that have completed the grafting work do not interfere with the grafting operation with the rootstock in the grafting mechanism. As shown in FIG. 2, the cutting order of the spikes 7 in the transporting means 9 is executed from the right side to the left when viewed from the downstream side in the traveling direction of the tray 4, and the grafting work is similarly performed in the downstream direction in the traveling direction in the tray 4 on the transporting means 8. You can run from right to left as seen from the side.

The scion hand mechanism 56 in the scion cutting mechanism section 2 has one support 58 having a holding body 57 for holding each stalk 7a at its lower end, and vertically driving the support 58. An actuator 59 including a hydraulic cylinder, an air cylinder, and the like, and a traveling platform 6 that is equipped with this actuator 59 and can reciprocate laterally along a gate-shaped frame 55.
It consists of 0 and.

One embodiment of the holding body 57 is a flexible hollow bag having a groove 57a which is open toward the upstream side in the traveling direction of the tray 4, and comprises a high pressure air supply means (not shown) (for example, a compressor or air). From the tank etc.) to the pipe 57
b and the control valve 57c capable of controlling the inflow / exhaust of air, when high pressure air is flown into the holding body 57, the groove 57 is formed.
The interval between a is narrowed, the stem 7a can be held, and when air is discharged, the groove 57a is opened and the holding can be released. In this case, if the back side of the holding body 57 (the side opposite to the groove 57a is adhered to a solid member such as a metal plate), displacement of the holding body 57 due to inflow and outflow of air is prevented. In addition, it is preferable to ensure a wide and narrow movement of the gap of the groove portion 57a.In another embodiment, although not shown, a pair of left and right finger portions are driven wide and narrow by an actuator to hold the stem 7a. It may be configured to be held or released.

The grafting mechanism 3 which will be described later on the cuttings 7 after cutting
60 as a transfer means for laterally moving toward
Is attached to a part of a timing belt 63, which is slidably supported by guide shafts 61, 61 on the gate-shaped frame 55 and is wound around pulleys 62, 62 provided on both left and right ends of the gate-shaped frame 55. When the drive motor that can rotate in the forward and reverse directions is not operated, the configuration is such that the grafting mechanism can be laterally moved to three locations, which will be described later.

With this structure, the left and right hull-shaped guide plates 30
The rear end surface of the stem 7a of the spike 7 that has stopped advancing in the gap 29 between the side surfaces of the sprocket is brought into contact with the holding bar 31 that is horizontally rotated from the rearward position to the front lateral direction by the operation of the actuator 32. Positioning and then the other actuator 32
Is operated to horizontally rotate the holding bar 31 facing forward in the rearward and lateral direction, and the stem 7a is sandwiched between the holding bars 31 and 31 to be positioned and held as shown by the solid line in FIG.

Next, the upper end side of the stem 7a of the spike 7 is held by the pair of left and right holding portions 57, 57 of the support 58 lowered to the upper surface of the inclined guide plate 39 by the operation of the actuator 59 so as not to fall. To have. Next, the cutting means 33 travels to cut only one stem 7a of the spike 7 into a slanted shape (lower position on the upstream side of conveyance and higher position on the downstream side of conveyance). The cutter means 33 may be a rotary blade similar to the cutter means 21 provided in the preliminary cutting mechanism section 13.

The stem 7a on the upper end side of the cut-off cutting 7 is moved toward the grafting mechanism 3 to be described later while being held at a high position by raising the support 58. Note that FIG.
And the curtain plate 64 disclosed in FIG. 18 is for partitioning so that the true leaves of the one already grafted by the grafting mechanism section 3 described later do not interfere with the grafting operation in the grafting mechanism section 3. Reference numeral 64 is a structure that is attached to the traveling platform 60 and horizontally moves integrally.

When all the cutting work of the horizontal row of spikes is completed, the spikes 7 in the rear row are guided by the guide groove 40 in the inclined guide plate 39.
In order to send to the location, the actuator 32 is reversely operated to return the holding bar 31 to the posture substantially parallel to the transport direction, and the transport means 9 is intermittently driven. Next, the grafting mechanism section 3 will be described with reference to FIGS. 21 to 24. The grafting mechanism section 3 includes a pair of front and rear guide bodies 65 and 66 and each of the guide bodies 65 and 66, at least each of the stem guide portions 67.
And a guide body for moving the stem 7a of the scion 7 to an approaching position where the stem 7a can hold the outer circumference of the stem 7a and an isolation position where the stem 7a is inserted into and removed from the stem guides 67, and the guide body. At positions below 65 and 66, a holding means 69 for holding the stem 6a of the rootstock 6 and the stem 7a of the scion 7 so as to join the cut surface portions of both stems, and the joining portion Adhesive supply means 70 for supplying adhesive toward the outer circumference of the stem
With. When the adhesive is a two-component type composed of a main agent and a curing agent, a curing agent supply means 71 for supplying the curing agent toward the adhesive (main agent) attached to the joint is added.

These means are arranged in association with a gate-type frame 72 that laterally extends above the conveying means 8 of the tray 4 for the stock 6. The hull-shaped guide plates 73 are arranged with a predetermined gap allowing the stems 6a to pass through at every left-right interval between the stems 6a of the side-by-side rootstocks 6 in the tray 4.
Is fixed to the gate-shaped frame 72 via a support rod 74. A pair of rotary actuators 75, 76 are attached to the upper surface of each guide plate 73,
The operating bar 77 extending upward from the upper end of the base 76 and the like has a base 6
And the supporting portions 78 and 79 for holding the stems of the spikelets 7 in the postures of substantially the same axis are configured to horizontally rotate between the solid line state and the one-dot chain line state in FIG. 22 (FIG. 21 and (See FIG. 22). The stem 6 a of the rootstock 6 is placed between the light projecting portion 87 and the light receiving portion 88 of the optical sensor provided on the upper surface of the guide plate 73.
Detecting that the tray 4 has passed, the intermittent movement of the tray 4 in the direction of arrow A is temporarily stopped, and the stop position is the stem 7 of the scion 7 held by the stem guides 67 of the pair of front and rear guide bodies 65, 66.
The axis of a and the stem 6a of the rootstock are controlled to be substantially the same axis.

The pair of front and rear guide bodies 65, 66 are movable to the left and right along the upper surface of the gate type frame 72.
0 is attached to a pinching / expanding drive means (manipulator) 68 projecting to the rear surface (downstream side of the tray 4 in the transport direction). In the embodiment, as shown in FIG. Each of the funnels has an upwardly expanding funnel and is divided in half. When the pinching / expanding driving means 68 is operated in the forward direction, the front and rear guide bodies 65 and 66 are separated from each other on the left and right sides about the axis 90 (see FIG. When the pinching / expanding driving means 68 is operated in the opposite direction, the two guide bodies 6 are moved.
5 and 66 are combined from the left and right sides at 90 axes,
The stalk guide portion 67 having a small diameter moves so that the stalk 7a of the scion 7 can be guided along the direction of the axis 90 (in the solid line state in FIG. 23).

The traveling operation console 80, as shown in FIG.
Guide rails 81 provided on the upper surface of the gate-shaped frame 72,
It is reciprocally movable to the left and right via a timing belt 80 which is supported by 82 and is moved by a driving means (not shown). , A drive pump 85 for injection,
86 and 86 are mounted. As shown in FIGS. 21 and 24, the ejection nozzles (arranged at 120 ° intervals along the circumferential direction), which are the adhesive supply means 70 for supplying the adhesive, are attached to the outer circumference of the stem only during the supply. It rotates substantially horizontally around the drive portion 91 so as to approach. A nozzle as the curing agent supply means 71 (opposed in 180 degrees in the embodiment) is provided at a lower portion of the inner side surface of the narrowing and expanding drive means 68.

Next, the grafting operation of the grafting mechanism 3 will be described. As shown in FIG. 21, due to the intermittent movement of the feeding means 8 (belt conveyor), the tray 4 on which the rootstock 6 having the slanted cutting surface formed on the upper end of the stem 6a is planted intermittently moves in the direction of arrow A. As shown in FIG. 22, of the rootstocks 6 stopped at a predetermined position between the side surfaces of the left and right guide plates 73 arranged in parallel, the rear end surface of the stem 6a to be grafted is rotated to the rear side. Positioning is performed by abutting on the support portion 79 at the tip of the actuation rod 77 that is horizontally rotated in the front lateral direction from the rearward position by the operation of the die actuator 76.

At approximately the same time as this operation, the traveling operation console 80 laterally moves to above the location of the rootstock to be grafted, and the distance between the pair of front and rear guide bodies 65, 66 is narrowed so that the narrowing / expanding drive means 6 is provided.
8 is activated. At this time, as shown in FIG. 23, the support 5 on the traveling platform 60 in which the gate-shaped frame 55 is laterally moved.
The stem 7a of the spikelet carried by the two guides 65, 6
6 above (see FIG. 21), the actuator 59
Is operated to lower the support 58, insert the stalk 7a into the stalk guide portion 67 so that the stalk 7a is fitted, and open the holding body 57 to release the holding.

As a result, the stem 7a of the scion is guided by the stem guide portion 67.
The slanted cut surfaces are brought close to each other on the stem 6a of the rootstock while being guided by. In this state, when the other (front side) rotary actuator 75 is operated to horizontally rotate the forward operating rod 77 rearward and laterally, the support portion 78 at the tip of the operating rod 77 causes the stem 78 of the spike 7. Since 7a is pushed in the direction of arrow A, the cutting surfaces of both the stems 6a and 7a are held in position so that they are in close contact with each other. The traveling platform 60 in which the hugging of the spikes 7 has been released returns to the original position (on the side of the conveying means 9), and the cutting work of the stem of the next spikes 7 is executed.

Next, the drive unit 91 is operated so that the ejection nozzle of the adhesive supply means 70 approaches the outer periphery of the joint between the two stems 6a, 7a, and the drive pump 85 is operated to remove the adhesive from both stems. It is attached to the outer periphery of the joint portion of 6a and 7a. Next, after the injection nozzle is moved away by the reverse operation of the drive unit 91, the curing agent supply unit 71 provided in the narrowing and expanding drive unit 68.
The spray is sprayed toward the surface of the adhesive adhered to the outer circumferences of both stems, and the postures of both stems 6a and 7a are maintained by the rotary actuators 75 and 76 for a short period of time.

The adhesive used in this embodiment is a so-called two-component type instant adhesive which is cured by adding a curing agent. In the case of a so-called UV curable adhesive, which is a modified acrylic resin adhesive and is cured in seconds by ultraviolet irradiation, it is necessary to provide an ultraviolet irradiation means instead of the curing agent supply means. Further, in the case of a one-component instant adhesive such as a cyanoacrylate resin, a curing agent supply means is unnecessary.

When the grafting work of the scion 7 to the rootstock 6 is completed, the interval between the pair of front and rear guide bodies 65 and 66 is widened (see the chain double-dashed line in FIG. 23), and the traveling operation console 80 is inserted via the timing belt 89. It is moved in the direction of arrow K, and the grafting work for the rootstock 6 at the right lateral position is started. By repeating such cycle control, the scion 7 can be grafted one by one to the rootstocks 6 arranged in a horizontal row.
The grafted seedling 100, which has thus completed grafting, is moved toward the discharge conveyor 10 while being placed on the tray 4. Reference numeral 92 is a control unit such as a computer for controlling the driving timing of each of the above means.

As shown in FIG. 2, the cutting height H1 position of the scion 7 in the scion cutting mechanism 2 in the above-described embodiment is set to the root 6 in the grafting mechanism 3 connected to the side thereof. If it is set so as to be higher than the joining work height position H2, the stem 7a of the spike 7 is cut by the cutter means 33 at the position of the supply means 9, and then the actuator 59 is operated to operate the support body 58. The pedestal 7a can be moved to the upper part of the guide bodies 65 and 66 by moving the traveling platform 60 laterally without raising, and a part of the raising and lowering operation of the support body 58 can be omitted. As a result, it is possible to speed up the cycle as described above, and it is possible to realize a quick and efficient grafting work. Further, as described above, when the joining and fixing work of the scion is completed while the rootstock is still planted in the tray, the grafting work can be made efficient and damage to the root of the rootstock can be completely eliminated. Play.

In the above-mentioned embodiment, the six rootstocks and spikes were lined up in parallel in the tray advancing direction, but they may be arranged in a line in the tray advancing direction. good. Then, the stem 6a of the rootstock 6 that is still planted in the pot portion 5 of the tray 4 may be cut off, and in that state, the spikes 7 may be joined and fixed. Prior to this, the upper part of the stem 6a of the rootstock 6 may be manually cut and removed at another location in advance. The present invention may be configured such that a plurality of the grafting mechanism portions 3 are arranged so that the scions are simultaneously attached to a plurality of parallel rootstocks.

[0041]

As described above, in the grafted seedling production apparatus of the present invention, means for guiding the stem of the rootstock and the stem of the scion substantially along the axes of both stems, A holding means for holding the posture so as to join the cut surface portions of both stems, and an adhesive supply means for supplying an adhesive toward the outer circumference of the stem of the joint portion. Since the adhesive is simply attached to the outer circumference of the joint between the stem and the stem of the scion, there is little labor for fixing and there is little risk of damaging the seedling. Then, as the grafted seedling grows after joining and fixing, the adhesive after rooting peels off from the stem of the plant almost automatically, so post-treatment can be extremely simple and the cost of producing grafted seedlings is low. Play.
