Embodiments of the present invention will be described. Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Embodiment 1 FIG. 1 is a partially cutaway front view of a main part of a grafted seedling temporary planting apparatus 100 of the present invention, FIG. 2 is a plan view of a main part of the grafted seedling temporary planting apparatus 100 of the present invention, and FIG. It is a partially cutaway side view of the main part of the invention grafted seedling temporary planting device 100,
FIG. 4 is a time chart of the operation of the grafted seedling temporary planting apparatus 100 of the present invention. FIG. 5 is an overall plan view of the automatic grafting device 1, and FIG. 6 is a side view of the entire automatic grafting device 1.

The example shown in the figure is an automatic grafting device 1 for cutting and grafting the root pots of cucurbit vegetables, which are cut from rootstock seedlings A and cut from rootstock seedlings B. A case where the grafted seedling E is produced by grafting with the scion will be described.

Machine frame 2 of automatic grafting device 1 (FIGS. 5 and 6)
A compressor (not shown) and solenoid valves (not shown) are provided in the lower part of the inside, and a rootstock seedling box feeder (not shown in FIG. 5), a spikelet feeder (not shown) in FIG. A stock supply device 5a, a scion supply device 5b, a stock alignment device 6a, a scion alignment device 6b, a stock and scion grafting device 7, a conveying belt means 11, a grafted seedling temporary planting device 100, and the like are provided.

The transport belt means 11 includes a transport belt 11
a, 11b, 11c, the rootstock seedling box supply device mounts a rootstock seedling box (a) for storing rootstock seedlings A having seedlings on the upper side of the conveyor belt 11a, and moves to a predetermined position. It is configured to transfer sequentially. Further, the scion seedling box supply device is configured to mount a scion seedling box (b) for accommodating scion seedlings B having seedlings on the upper side of the transport belt 11b and to sequentially transfer the scion seedling boxes to a predetermined position. .

The grafting seedling box supply device includes a conveyor belt 1
A grafting seedling box (c) in which a predetermined amount of soil is put in a concave portion is mounted on the upper side of 1c, and is sequentially transferred to a predetermined position.

The rootstock seedling A mounted on the rootstock seedling box supply device and accommodated in the rootstock seedling box (a) transferred to a predetermined position is:
Taken over by the stock supply device 5a, both are gripped by a gripping hand and a cutting cutter (not shown), cut the root of the hypocotyl, and then sent to the stock alignment device 6a to align the direction of cotyledon development. While being transferred to the stocking and scion grafting device 7.

Further, the scion seedlings B stored in the scion seedling box (b) mounted on the scion seedling box supply device and transferred to a predetermined position.
Are taken over by the scion supply device 5b, are gripped by a gripping hand and a cutting cutter (not shown), the roots of their hypocotyls are cut, and then sent to the scion alignment device 6b to develop cotyledons. Are transferred to the stocking and scion grafting device 7 while their directions are aligned.

In the cutting of the root portion of the hypocotyl of the rootstock seedlings A and B, especially in cucurbits, the rooting period is short because the seedling raising period is short, and the treatment with the rootstock is unstable. However, it is possible to stabilize the grafting treatment by cutting the roots, and to solve the problem of the growth difference after grafting by adjusting the roots to the same height.

At the grafting position of the stocking and scion grafting device 7, the cut portion of the stock and the cutting of the scion are joined, and a clip supplied from a grafting joining device (not shown) is used.

The pot 21 is filled with soil 22 for temporary planting in another device (not shown).

A vertical hole 23 is formed substantially in the center of the pot 21 in the soil 22 for temporary planting of the pot 21 so that the grafting seedling E can be easily planted. If the vertical hole 23 is drilled when filling the temporary planting soil 22 with another device (not shown), the center position of the vertical hole 23 is broken or the vertical hole 23 collapses during transportation. The hole is punched by the hole punching means 110 immediately before.

As shown in FIG. 1, the perforating means 110 of this embodiment is provided for one row of the pot 21 (in the illustrated case,
a, 21b,..., 21f), and a piercing needle 112 comprising a piercing needle mounting arm 112g.

Bearing bush 11 that slides up and down freely by loosely fitting
6. A mounting bracket 117 extending from the bearing bush 116 and supporting the piercing needle mounting arm 112g.
One end is fixed to the mounting bracket 117, and the other end is constituted by an urging spring 114 attached so as to urge the tray pressing plate 113 downward.

The tray holding plate 113 presses the cell tray 20 so that the cell tray 20 does not rise when the hole is punched, and loosely fits the punching needles 112a,..., 112f, and guides the hole punching needle 112 when the punching cylinder 111 is lowered. A hole (not shown) is provided.

The punching means 110 is provided above the transport belt 11c, on the front side of the temporary planting means 101 with respect to the traveling direction of the transport belt 11c.

Further, in order to stop the grafted seedling box (c) on the transport belt 11c, which is mounted on the transport belt 11c and is transferred, at a predetermined position P (FIG. 3), a grafted seedling box comprising position detecting sensors 91 and 92 is provided. Position detecting means is provided.

The operation of the perforating means 110 will now be described with reference to the provisional planting means 101 of the grafting seedling provisional planting apparatus 100 and the conveying belt means 1.
1 and FIG. 4 in connection with the operation of the grafted seedling box (c).

The pot 21 of the cell tray 20 accommodated in the under tray 25 of the grafted seedling box (c) is filled with soil 22 for temporary planting in another device (not shown). The grafting seedling box (C) is transported by the grafting seedling box feeding device.
1c and transferred to the grafted seedling temporary planting device 100.

When the grafted seedling box (c) on the conveyor belt 11c reaches the tray punching position P (FIG. 3), the detection sensor 91 at the punching position P sends a detection signal to a control device (not shown). The transport belt 11c stops. The position detection sensor 91 includes a light emitting device 91a fixed to one machine frame 2 and a light receiving device 91b fixed to the machine frame 2 on the opposite side across the conveyor belt 11c. The emitted light beam passes through the gap 24 (FIG. 3) between the cell tray 20 and the under tray 25 and reaches the light receiver 92b.
The light emitting device 91a and the light receiving device 9 are arranged such that the position where the wall of the pot 21 of the cell tray 20 blocks the light beam is a hole forming position P.
If 1b is attached, the control device can stop the grafting seedling box (c) when the conveyor belt 11c and thus the grafting seedling box (c) reaches the tray punching position P in response to the light beam cutoff signal.

Similarly, the position detection sensor 92 is connected to one of the
And a light receiver 92b fixed to the machine frame 2 on the opposite side of the conveyor belt 11c,
Normally, the light beam emitted from the light emitter 92a passes through the gap 24 between the cell tray 20 and the under tray 25 and reaches the light receiver 92b. If the light-emitting device 92a and the light-receiving device 92b are mounted so that the position where the wall of the pot 21 of the cell tray 20 blocks the light beam is the temporary planting (seedling insertion) position R, the control device receives the light-blocking signal and sets the transport belt. 11c, therefore, the grafted seedling box (c) can be stopped when it reaches the temporary planting (seedling insertion) position R (FIG. 3).

When the pots 21 of the cell tray 20 having different pitches are used, the position detecting sensors 91 and 9 are used.
The mounting position of 2 may be adjusted.

After the grafted seedling box (c) arrives at the tray punching position P and stops, the punching cylinder 111 of the punching means 110 operates to push down the punching needle 112. The vertical movement of the piercing needle 112 is controlled by the shaft 1 set up on the machine frame 2.
15 and is smoothly guided by a bearing bush 116 which is loosely fitted on the shaft and is slidable in the vertical direction. The piercing needle mounting arm 112g of the piercing needle 112 and the piercing cylinder 111 are connected via a cylinder rod 111a whose length can be adjusted.

Since the length of the cylinder rod 111a is adjustable, it is possible to easily cope with the case where the pot 21 of the cell tray 20 has a different depth by changing the depth of the vertical hole 23.

When the cylinder rod 111a drives the perforating needle mounting arm 112g downward by a required distance, the perforating needle mounting arm 112g has a diameter suitable for temporary planting and a required length, and a row of pots 21. Since the perforating needles 112a, 112b,..., 112f of the same pitch and number are fixed vertically downward, the vertical holes 23 for one row of pot holes are punched at a predetermined position all at once at a predetermined depth. be able to.

When the piercing needle mounting arm 112g is driven downward, the tray pressing plate 113 is attached to the mounting bracket 1.
Since the cell tray 20 is urged downward by the urging spring 114 via 17, the easily deformable cell tray 20 formed of a thin synthetic resin plate does not rise or deform during drilling. , And holes for loosely fitting the piercing needles 112 provided on the tray pressing plate 113 are formed by the piercing needles 112a, 112b,.
Guide the position of f.

If the cell tray 20 has a different number of holes or different pitches of the pots 21, the mounting bracket 1
17 is removed, and a piercing needle arm 11 having a piercing needle 112 adapted to the number of holes or the pitch of the pot 21 is removed.
Replace with 2g and tray holding plate 113.

After the perforation of the vertical hole 23 is completed, the perforating cylinder 111 is operated to drive the perforating needle mounting arm 112g upward, so that the perforating needles 112a, 112b,.
・ 112f rises all at once, but the tray holding plate 11

0 is spaced above the cell tray 20.

After the perforation is completed, the conveyor belt 11c starts moving again, and stops when the position of the pot 21 of the grafted seedling box (c) reaches the temporary planting position R where the seedlings are inserted.

In the meantime, the grafted seedlings E grafted by the stocking and scion grafting device 7 are grasped by the grasping hand of the stocking and scion grafting device 7 and taken over by the temporary planting means 101. Waiting at the point.

Temporary planting means 101 previously released
Gripping hand mechanism 120 is a gripping hand pushing mechanism 1
When reaching the point Q which is extruded by 30 and receives the grafted seedling E, the grafted seedling E is taken over and gripped. Next, the gripping hand of the rootstock / spike grafting device 7 is opened to release the gripping of the grafted seedling E.

Thereafter, the gripping hand mechanism 120 of the temporary planting means 101 keeps holding the grafted seedling E until the temporary planting end point S.

The gripping hand mechanism 120 retreats to a position where it does not interfere with the stock / spike grafting device 7 by retreating the gripping hand pushing mechanism 130, and then turns 90 degrees by the gripping hand rotating mechanism 140 to prepare for temporary planting. .

Simultaneously with the rotation of the gripping hand rotating mechanism 140, the gripping hand moving mechanism 150 starts moving. Further, the gripping hand pushing mechanism 130 is moved to the pushing position so that the grafted seedling E does not interfere with each part of the temporary planting means 101. The amount of movement of the grasping hand moving mechanism 150 is added to the amount of pushing of the grasping hand pushing mechanism 130 so that the position of the grafted seedling E is immediately above the center of the pot 21 at the temporary planting position S where the seedling is inserted. Is controlled by

Here, the center position of the pot 21 into which the seedlings of the grafted seedlings E are inserted is, as shown in FIG.
Starting from 1a, approach the seedling receiving position Q point sequentially 21
, 21c,..., 21f.

When the position of the grafted seedling E reaches just above the center of the pot 21a into which the seedling is inserted, the gripping hand moving mechanism 150 is stopped, and the gripping hand lowering mechanism 160 is lowered. Finally, the soil pressing cylinder 166 descends and pushes the hypocotyl of the grafted seedling E into the vertical hole 23 of the pot 21a.
By pressing the soil, the temporary planting of the first row and first pot 21a of the cell tray 20 is completed.

Thereafter, the gripping hand mechanism 120 is opened to release the gripping, the gripping hand mechanism 120 is separated from the hypocotyl part of the grafted seedling E, and then the gripping hand pushing mechanism 130 is retracted, and the gripping hand mechanism 120 and the grafted seedling are moved. E so as not to come into contact with it, and then raise the soil pressing cylinder 166 and the gripping hand lowering mechanism 160 to move the gripping hand moving mechanism 1
The gripping hand rotation mechanism 140 is turned back, and the gripping hand mechanism 120 is returned to the initial position.

In the meantime, the next grafted seedling E is held at the seedling receiving position Q in order to be gripped by the gripping hand 17 of the rootstock / spike grafting device 7 and taken over by the temporary planting means 101.

Hereinafter, the temporary planting means 101 repeats the same operation as described above, but the stop position of the gripping hand moving mechanism 150 is controlled so as to be immediately above the pots 21b, 21c,.

The pots 21a, 21b, 21c,...
When the temporary planting of the cell tray 21f is completed and the temporary planting of the first row of the cell tray 20 is completed, the conveyor belt 11c starts moving, and the center of the pot 21 in the next row (the third row in the example in the figure) is formed with a hole. When reaching the predetermined position P directly below 110, the conveyor belt 11c is stopped and the vertical hole 23 is made. After the perforation is completed, the conveyor belt 11c starts moving again and stops at the temporary planting position R where the seedlings in the second row of the cell tray 20 are inserted.

Thereafter, the same operation as above is repeated again, and temporary planting is performed up to the last row (the twelfth row in the example shown in FIG. 5) of the cell tray 20, and when the temporary planting of the first cell tray 20 is completed, the second cell tray 20 Perform temporary planting.

Thus, according to the above embodiment of the present invention, in the automatic grafting device 100, the grafting seedlings E are placed in the temporary grafting means 101 immediately before the temporary grafting is sequentially performed at the pot hole positions for one row of the grafting seedling box (c). A vertical hole 23 is formed in the temporary planting soil 22 filled in the pot 21 of the grafted seedling box (c) in one row of the pot 21 at a time.
Is accurate, the wall of the hole 23 is less likely to collapse, and the number and the pitch of the pots 21 can be easily changed, so that the grafted seedlings E grafted by the automatic grafting device 100 can be efficiently planted efficiently. In addition, there is an excellent effect that various cultivation conditions can be easily handled.
