Description

本発明は、苗切断装置及び接ぎ木システムに関する。 The present invention relates to a seedling cutting device and a grafting system.

土壌病害対策や収量向上の一助として接ぎ木の利用が世界的に増加している。従来、接ぎ木において台木苗と穂木苗とを切断する方法として、Ｖ字型台木切断刃及びＶ字型穂木切断刃を用いて台木苗と穂木苗を別々に切断する方法（特許文献１参照）や、回転する２枚のカット刃で台木と穂木をカットする方法（特許文献２参照）が知られている。また、穂木及び台木を異なる位置で切断する方法も知られている（例えば、特許文献３、４等参照）。 The use of grafts is increasing worldwide as an aid to soil disease control and yield improvement. Conventionally, as a method of cutting rootstock seedlings and scion seedlings in grafting, a method of separately cutting rootstock seedlings and scion seedlings using a V-shaped rootstock cutting blade and a V-shaped scion cutting blade ( Patent Document 1) and a method of cutting a rootstock and scion with two rotating cutting blades (see Patent Document 2) are known. Further, a method of cutting the scion and the rootstock at different positions is also known (see, for example, Patent Documents 3 and 4 and the like).

特開２００５−１４３３９５号公報Japanese Unexamined Patent Publication No. 2005-143395 特開２００５−２１１０４６号公報Japanese Unexamined Patent Publication No. 2005-21014 特開平７−２７４７１６号公報Japanese Unexamined Patent Publication No. 7-274716 特開２０１１−１３５８０１号公報Japanese Unexamined Patent Publication No. 2011-135801

しかしながら、上記特許文献１、２等では、同軸上で台木と穂木を同時に切断しているものの、切断後の穂木と台木との間に一定の間隔が生じるため、穂木や台木を上下動させて、切断後の穂木と台木を合わせるための機構が必要となる。また、上記特許文献３、４等では、切断後の穂木と台木が接触するように移動させる機構が必要となる。 However, in the above-mentioned Patent Documents 1 and 2, etc., although the rootstock and the scion are cut at the same time on the same axis, a certain distance is generated between the scion and the rootstock after cutting, so that the scion and the scion are cut. A mechanism is required to move the tree up and down to match the scion and rootstock after cutting. Further, in Patent Documents 3 and 4, etc., a mechanism for moving the scion and the rootstock after cutting so as to come into contact with each other is required.

したがって、これらの技術では、切断後の穂木と台木を接触させるための機構を用意するのにコストがかかったり、切断後の穂木と台木を接触させるための処理工程が必要になることによる作業効率の低下が懸念される。 Therefore, in these techniques, it is costly to prepare a mechanism for contacting the scion and the rootstock after cutting, and a processing step for contacting the scion and the rootstock after cutting is required.

以下、接ぎ木システムの一実施形態について、図１〜図１０に基づいて詳細に説明する。 Hereinafter, one embodiment of the grafting system will be described in detail with reference to FIGS. 1 to 10.

図１には、本実施形態の接ぎ木システム１００の概要が示されている。接ぎ木システム１００は、図１に示すように、回転台としての回転テーブル２０を有しており、時計回り方向に３０°ずつ間欠的に回転する回転テーブル２０に対して、「（Ａ）穂木・台木の供給」処理、「（Ｂ）穂木・台木の切断」処理、「（Ｃ）穂木・台木の接合」処理、「（Ｄ）接合された苗の排出」処理の４つの処理を順次実行することで、接ぎ木を自動的に実行するシステムである。 FIG. 1 shows an outline of the grafting system 100 of the present embodiment. As shown in FIG. 1, the grafting system 100 has a rotary table 20 as a turntable, and the grafting system 100 has "(A) scion" with respect to the rotary table 20 which rotates intermittently by 30 ° in the clockwise direction.・ "Supply of rootstock" processing, "(B) Cutting of scion / rootstock" processing, "(C) Joining of scion / rootstock" processing, "(D) Discharging of joined seedlings" processing 4 It is a system that automatically executes grafting by executing two processes in sequence.

図２には、接ぎ木システム１００のブロック図が示されている。本実施形態では、「（Ａ）穂木・台木の供給」処理は、図２に示す苗供給部１２が実行し、「（Ｂ）穂木・台木の切断」処理は、苗切断装置としての苗切断部１４が実行し、「（Ｃ）穂木・台木の接合」処理は、接ぎ木装置としての苗接合部１１０が実行し、「（Ｄ）接合された苗の排出」処理は、苗排出部１１２が実行する。このうち、「（Ａ）穂木・台木の供給」処理においては、予め本葉が切除されている台木と、予め根鉢が切除されている穂木とが回転テーブル２０に対して供給される。なお、台木及び穂木のいずれかに、子葉を残すこととしてもよいし、台木及び穂木には子葉を残さないようにしてもよい。また、「（Ｂ）穂木・台木の切断」処理においては、穂木と台木を切断し、穂木の切断面の少なくとも一部と台木の切断面の少なくとも一部とを合わせた状態にするまでの工程を行い、その後、切断面が合わせられた状態で穂木と台木は移動する。また、「（Ｃ）穂木・台木の接合」処理では、移動してきた接ぎ木苗の合わせた部分を接合資材（テープ）で覆い、合わせた部分がずれないようにする（以下、「接合」という）。なお、苗供給部１２、苗切断部１４、苗接合部１１０、苗排出部１１２は、制御装置１０により制御される。 FIG. 2 shows a block diagram of the grafting system 100. In the present embodiment, the "(A) scion / rootstock supply" process is executed by the seedling supply unit 12 shown in FIG. 2, and the "(B) scion / rootstock cutting" process is performed by the seedling cutting device. The seedling cutting section 14 as a grafting device executes the "(C) joining of scion and rootstock" process, and the seedling joining section 110 as a grafting device executes the "(D) discharging of the joined seedlings" process. , Seedling discharge unit 112 executes. Of these, in the "(A) Supply of scion / rootstock" process, the rootstock from which the true leaves have been cut in advance and the scion from which the root pot has been cut in advance are supplied to the rotary table 20. Will be done. The cotyledons may be left on either the rootstock or the scion, or the cotyledons may not be left on the rootstock or the scion. Further, in the "(B) cutting of scion / rootstock" process, the scion and rootstock were cut, and at least a part of the cut surface of the scion and at least a part of the cut surface of the rootstock were combined. After that, the scion and the rootstock move with the cut surfaces aligned. In addition, in the "(C) scion / rootstock joining" process, the joined part of the grafted seedlings that have moved is covered with a joining material (tape) so that the joined part does not shift (hereinafter, "joining"). ). The seedling supply unit 12, the seedling cutting unit 14, the seedling joint unit 110, and the seedling discharge unit 112 are controlled by the control device 10.

図３は、接ぎ木システム１００の回転テーブル２０を上方（＋Ｚ側）から見た状態が示されている。回転テーブル２０は、上側テーブル２６Ａと、上側テーブル２６Ａの下側（図３の場合、紙面奥側）に設けられた下側テーブル２６Ｂと、を有する。上側テーブル２６Ａと下側テーブル２６Ｂは、同一径の円盤状部材であり、上下方向（図３のＺ軸方向）に所定間隔をあけた状態で、回転軸１２０に固定されている。上側テーブル２６Ａと下側テーブル２６Ｂは、制御装置１０の制御の下、図２に示す回転テーブル駆動装置２２により、所定時間間隔で、間欠的に３０°ずつ時計回り方向に回転駆動される。 FIG. 3 shows a state in which the rotary table 20 of the grafting system 100 is viewed from above (+ Z side). The rotary table 20 has an upper table 26A and a lower table 26B provided on the lower side (in the case of FIG. 3, the back side of the paper surface) of the upper table 26A. The upper table 26A and the lower table 26B are disk-shaped members having the same diameter, and are fixed to the rotating shaft 120 in a state of being spaced apart from each other in the vertical direction (Z-axis direction in FIG. 3). The upper table 26A and the lower table 26B are intermittently driven to rotate clockwise by 30 ° at predetermined time intervals by the rotary table driving device 22 shown in FIG. 2 under the control of the control device 10.

上側テーブル２６Ａの上面の外周部近傍には、図３に示すように、穂木１０２（図４参照）を把持する第１把持部としての上側把持機構２４が３０°間隔で設けられ、各上側把持機構２４の近傍には、テープ引き出し機構３９が設けられている。また、下側テーブル２６Ｂの上側把持機構２４に対向する位置（−Ｚ側）には、台木１０４を把持する第２把持部としての下側把持機構１２４が設けられている（図４参照）。すなわち、下側テーブル２６Ｂの下面の外周部近傍には、３０°間隔で下側把持機構１２４が設けられている。 As shown in FIG. 3, upper gripping mechanisms 24 as a first gripping portion for gripping the scion 102 (see FIG. 4) are provided at intervals of 30 ° in the vicinity of the outer peripheral portion of the upper surface of the upper table 26A, and each upper side is provided. A tape pulling mechanism 39 is provided in the vicinity of the gripping mechanism 24. Further, at a position (-Z side) of the lower table 26B facing the upper gripping mechanism 24, a lower gripping mechanism 124 is provided as a second gripping portion for gripping the rootstock 104 (see FIG. 4). .. That is, the lower gripping mechanism 124 is provided at intervals of 30 ° in the vicinity of the outer peripheral portion of the lower surface of the lower table 26B.

なお、上側把持機構２４が把持する穂木１０２の切断面（下端面）の少なくとも一部と、上側把持機構２４の鉛直方向下側に位置する下側把持機構１２４が把持する台木１０４の切断面（上端面）の少なくとも一部とが合わせられた状態で接ぎ木苗になる。また、接ぎ木苗は、回転テーブル２０により回転されるので、接ぎ木苗の移動経路は、回転テーブル２０の外周に沿った経路となっている。 It should be noted that at least a part of the cutting surface (lower end surface) of the scion 102 gripped by the upper gripping mechanism 24 and the rootstock 104 gripped by the lower gripping mechanism 124 located on the lower side in the vertical direction of the upper gripping mechanism 24 are cut. Grafted seedlings are formed with at least a part of the surface (upper end surface) aligned. Further, since the grafted seedlings are rotated by the rotary table 20, the movement path of the grafted seedlings is a route along the outer circumference of the rotary table 20.

なお、回転テーブル２０が停止した状態における把持機構２４、１２４の位置は、図３に示すように、時計の文字盤の数字の位置と対応する。したがって、以下においては、図３の最も＋Ｙ側の把持機構２４、１２４の位置を「１２時の位置」と呼び、１２時の位置から３０°時計回り方向にずれた位置を「１時の位置」、１時の位置から３０°時計回り方向にずれた位置を「２時の位置」と呼ぶものとする。すなわち、最も−Ｙ側の位置は、「６時の位置」となる。なお、本実施形態では、一例として、図１に示すように、「（Ａ）穂木・台木の供給」処理は、１２時の位置にある把持機構２４、１２４に対して実行され、「（Ｂ）穂木・台木の切断」処理は、３時の位置にある把持機構２４、１２４が保持する穂木及び台木に対して実行される。また、「（Ｃ）穂木・台木の接合」処理は、６時の位置にある把持機構２４、１２４が保持する穂木及び台木に対して実行され、「（Ｄ）接合された苗の排出」処理は、把持機構２４、１２４が７時の位置にある把持機構２４、１２４に対して実行される。 The positions of the gripping mechanisms 24 and 124 when the rotary table 20 is stopped correspond to the positions of the numbers on the clock face, as shown in FIG. Therefore, in the following, the positions of the gripping mechanisms 24 and 124 on the most + Y side of FIG. 3 are referred to as "12 o'clock positions", and the positions deviated by 30 ° clockwise from the 12 o'clock position are referred to as "1 o'clock positions". The position deviated by 30 ° clockwise from the 1 o'clock position is referred to as the "2 o'clock position". That is, the position on the most −Y side is the “6 o'clock position”. In the present embodiment, as an example, as shown in FIG. 1, the "(A) supply of scion / rootstock" process is executed for the gripping mechanisms 24 and 124 at the 12 o'clock position, and the "(A) scion / rootstock supply" process is executed. The "(B) cutting of scion / rootstock" process is executed for the scion and rootstock held by the gripping mechanisms 24 and 124 at the 3 o'clock position. Further, the "(C) grafting of scion and rootstock" process is executed on the scion and rootstock held by the gripping mechanisms 24 and 124 at 6 o'clock, and "(D) grafted seedlings". The "discharging" process is performed on the gripping mechanisms 24, 124 in which the gripping mechanisms 24, 124 are in the 7 o'clock position.

図４は、上側把持機構２４及び下側把持機構１２４近傍を拡大して示す斜視図である。図４に示すように、上側把持機構２４は、第１把持部材２９Ａ、第２把持部材２９Ｂ、力作用部３４、及び軸２２９を有する。第１把持部材２９Ａは、上側テーブル２６Ａの上面に固定されている。第２把持部材２９Ｂは、上側テーブル２６Ａの上面に、軸２２９を介して設けられている。これにより、第２把持部材２９Ｂは、軸２２９を中心として、Ｚ軸回りに回動可能とされている。力作用部３４は、第２把持部材２９Ｂの軸２２９近傍に固定されている。なお、力作用部３４には不図示のトーションバネの弾性力が常時付勢されており、力作用部３４及び第２把持部材２９Ｂには軸２２９を中心とした上方から見て時計回り方向の力が常時付勢されている。これにより、第２把持部材２９Ｂと第１把持部材２９Ａとの間で穂木１０２を保持できる（挟むことができる）ようになっている。なお、力作用部３４がトーションバネの付勢力に抗する力を受けた場合には、力作用部３４及び第２把持部材２９Ｂは、軸２２９を中心に反時計回り方向に回動し、保持していた穂木１０２を解放する。 FIG. 4 is an enlarged perspective view showing the vicinity of the upper gripping mechanism 24 and the lower gripping mechanism 124. As shown in FIG. 4, the upper gripping mechanism 24 has a first gripping member 29A, a second gripping member 29B, a force acting portion 34, and a shaft 229. The first gripping member 29A is fixed to the upper surface of the upper table 26A. The second gripping member 29B is provided on the upper surface of the upper table 26A via a shaft 229. As a result, the second gripping member 29B can rotate about the Z axis around the shaft 229. The force acting portion 34 is fixed in the vicinity of the shaft 229 of the second gripping member 29B. The elastic force of the torsion spring (not shown) is constantly urged to the force acting portion 34, and the force acting portion 34 and the second gripping member 29B are in the clockwise direction when viewed from above with respect to the shaft 229. The force is always urged. As a result, the scion 102 can be held (sandwiched) between the second gripping member 29B and the first gripping member 29A. When the force acting portion 34 receives a force that opposes the urging force of the torsion spring, the force acting portion 34 and the second gripping member 29B rotate and hold in the counterclockwise direction about the shaft 229. Release the scion 102 that had been doing.

下側把持機構１２４は、前述した上側把持機構２４と同様の構造を有する。すなわち、下側把持機構１２４は、図４に示すように、第１把持部材１２９Ａと、第２把持部材１２９Ｂと、力作用部１３４と、を有しており、第２把持部材１２９Ｂと第１把持部材１２９Ａとの間で台木１０４を保持できる（挟むことができる）ようになっている。ここで、第１把持部材１２９Ａの上側の面には、直方体状の第２誘導機構としての誘導部材１７０が設けられている。誘導部材１７０は、穂木１０２から力を受けて−Ｙ側に曲がった状態の台木１０４の茎部を第１把持部材１２９Ａと第２把持部材１２９Ｂが把持したときに、台木１０４の茎部の軸の向きを鉛直方向に矯正する力を付与する力付与部として機能している。なお、力作用部１３４に常時かかっている付勢力に抗する力を受けた場合には、力作用部１３４及び第２把持部材１２９Ｂは、保持していた台木１０４を解放する。 The lower gripping mechanism 124 has the same structure as the upper gripping mechanism 24 described above. That is, as shown in FIG. 4, the lower gripping mechanism 124 has a first gripping member 129A, a second gripping member 129B, and a force acting portion 134, and has a second gripping member 129B and a first gripping member 129B. The rootstock 104 can be held (sandwiched) between the grip member 129A and the grip member 129A. Here, a guide member 170 as a rectangular parallelepiped second guide mechanism is provided on the upper surface of the first grip member 129A. The guide member 170 receives a force from the scion 102 and bends to the -Y side. When the first gripping member 129A and the second gripping member 129B grip the stem of the rootstock 104, the stem of the rootstock 104 It functions as a force-giving part that gives a force to correct the direction of the axis of the part in the vertical direction. When the force acting unit 134 receives a force that opposes the urging force that is constantly applied to the force acting unit 134, the force acting unit 134 and the second gripping member 129B release the rootstock 104 that has been held.

上側把持機構２４それぞれの近傍（各把持機構２４の時計回り方向前方）に設けられたテープ引き出し機構３９は、＋Ｚ方向から見て略Ｕ字形状を有する固定部材２７と、固定部材２７に対して揺動可能に設けられたピン２８と、を有する。このテープ引き出し機構３９は、苗接合部１１０において接ぎ木苗の一部（穂木１０２と台木１０４が合わさった部分）を覆う接合資材（テープ）を引き出すために用いられる。すなわち、「（Ａ）穂木・台木の供給」処理や、「（Ｂ）穂木・台木の切断」処理では、テープ引き出し機構３９は用いられない。 The tape pull-out mechanism 39 provided in the vicinity of each of the upper gripping mechanisms 24 (clockwise forward of each gripping mechanism 24) has a substantially U-shaped fixing member 27 when viewed from the + Z direction, and the fixing member 27. It has a pin 28 provided so as to be swingable. This tape pulling mechanism 39 is used to pull out a joining material (tape) that covers a part of the grafted seedlings (the portion where the scion 102 and the rootstock 104 are combined) at the seedling joining portion 110. That is, the tape pull-out mechanism 39 is not used in the "(A) supply of scion / rootstock" process and the "(B) cutting of scion / rootstock" process.

次に、苗切断部１４について、詳細に説明する。図５、図６には、苗切断部１４の構成が示されている。なお、図５には、苗切断部１４の近傍（３時の位置）に存在する上側把持機構２４及び下側把持機構１２４が穂木１０２及び台木１０４を把持していない状態が示され、図６には、苗切断部１４の近傍（３時の位置）に存在する上側把持機構２４及び下側把持機構１２４が穂木１０２及び台木１０４を把持した状態が示されている。 Next, the seedling cutting portion 14 will be described in detail. 5 and 6 show the configuration of the seedling cutting portion 14. Note that FIG. 5 shows a state in which the upper gripping mechanism 24 and the lower gripping mechanism 124 existing in the vicinity of the seedling cutting portion 14 (position at 3 o'clock) do not grip the scion 102 and the rootstock 104. FIG. 6 shows a state in which the upper gripping mechanism 24 and the lower gripping mechanism 124 existing in the vicinity of the seedling cutting portion 14 (position at 3 o'clock) grip the scion 102 and the rootstock 104.

苗切断部１４は、図５に示すように、切断刃１３８と、第１誘導機構としての誘導部材１５０と、切断刃駆動機構１４２と、苗受け治具１３６と、苗受け治具保持部２３４と、苗受け治具駆動機構１４４と、前述した誘導部材１７０と、を備える。 As shown in FIG. 5, the seedling cutting portion 14 includes a cutting blade 138, an induction member 150 as a first guiding mechanism, a cutting blade driving mechanism 142, a seedling receiving jig 136, and a seedling receiving jig holding portion 234. The seedling receiving jig drive mechanism 144 and the above-mentioned guide member 170 are provided.

切断刃１３８は、穂木１０２の茎部及び台木１０４の茎部を同時に、かつ同一高さにおいて斜めに切断するための刃物である。切断刃１３８としては、市販の剃刀刃を用いることができる。切断刃１３８は、不図示のネジ等により誘導部材１５０に着脱可能（交換可能）に固定され、誘導部材１５０は、切断刃駆動機構１４２の移動部１４０Ｂに固定されている。図７（ａ）は、切断刃１３８及び誘導部材１５０と、穂木１０２及び台木１０４の、切断前の状態を概略的に示す斜視図であり、図７（ｂ）は、図７（ａ）を＋Ｙ方向から見た状態を示す図である。図７（ａ）、図７（ｂ）からわかるように、切断刃１３８は、その刃部（鋭利なエッジ部分）１３９がＹ方向に延びているとともに、全体がＸＹ面（水平面）及びＹＺ面に対して傾斜した状態となっている。切断刃１３８とＹＺ面との間の角度（図７（ｂ）において示す角度θ）は、例えば２０°〜３０°であるものとする。 The cutting blade 138 is a blade for cutting the stem of the scion 102 and the stem of the rootstock 104 at the same time and diagonally at the same height. As the cutting blade 138, a commercially available razor blade can be used. The cutting blade 138 is detachably (replaceable) fixed to the guide member 150 by a screw or the like (not shown), and the guide member 150 is fixed to the moving portion 140B of the cutting blade drive mechanism 142. FIG. 7A is a perspective view schematically showing the state of the cutting blade 138 and the guiding member 150, and the scion 102 and the rootstock 104 before cutting, and FIG. 7B is FIG. 7A. ) Is shown in the + Y direction. As can be seen from FIGS. 7 (a) and 7 (b), the cutting blade 138 has a blade portion (sharp edge portion) 139 extending in the Y direction, and the entire cutting blade 138 has an XY plane (horizontal plane) and a YZ plane. It is in a state of being inclined with respect to. The angle between the cutting blade 138 and the YZ surface (angle θ shown in FIG. 7B) is assumed to be, for example, 20 ° to 30 °.

誘導部材１５０は台形状の板部材であり、＋Ｚ側の面（誘導部材１５０の最も広い面）は、図７（ａ）に示すように、切断刃１３８の＋Ｚ側の面よりもわずかに高くなっている。このため、誘導部材１５０と切断刃１３８との間には、段差部１３７ａが形成されている。ここで、段差部１３７ａは、Ｙ軸方向と、切断刃１３８の移動方向（図７（ａ）の破線矢印方向）とに対して傾斜する方向（図７（ａ）において、Ｙ軸を基準とした角度αの方向）に延びている。なお、段差部１３７ａの作用については、後述する。 The guide member 150 is a trapezoidal plate member, and the surface on the + Z side (the widest surface of the guide member 150) is slightly higher than the surface on the + Z side of the cutting blade 138 as shown in FIG. 7 (a). It has become. Therefore, a step portion 137a is formed between the guiding member 150 and the cutting blade 138. Here, the step portion 137a is inclined with respect to the Y-axis direction and the moving direction of the cutting blade 138 (the direction indicated by the broken arrow in FIG. 7A) (in FIG. 7A, with reference to the Y-axis). It extends in the direction of the angle α). The action of the step portion 137a will be described later.

切断刃駆動機構１４２は、本体部１４０Ａと、本体部１４０Ａに対して図５に示す矢印Ａ，Ａ’方向に移動する移動部１４０Ｂとを有する。移動部１４０Ｂは、本体部１４０Ａ内に設けられたモータやエアシリンダ等により駆動される。ここで、矢印Ａ、Ａ’方向は、例えばＸＺ面内においてＺ軸に対して角度θ（θ＝２０°〜３０°）傾斜する方向であるものとする。移動部１４０Ｂには、上述した誘導部材１５０及び切断刃１３８が設けられている。このため、切断刃１３８は、切断刃駆動機構１４２により、図５に示す矢印Ａ、Ａ’方向に移動し、この移動により、穂木１０２及び台木１０４を切断する。 The cutting blade drive mechanism 142 has a main body portion 140A and a moving portion 140B that moves in the directions of arrows A and A'shown in FIG. 5 with respect to the main body portion 140A. The moving portion 140B is driven by a motor, an air cylinder, or the like provided in the main body portion 140A. Here, it is assumed that the arrows A and A'directions are inclined by an angle θ (θ = 20 ° to 30 °) with respect to the Z axis in the XZ plane, for example. The moving portion 140B is provided with the above-mentioned guiding member 150 and cutting blade 138. Therefore, the cutting blade 138 is moved in the directions of arrows A and A'shown in FIG. 5 by the cutting blade driving mechanism 142, and the scion 102 and the rootstock 104 are cut by this movement.

苗受け治具１３６は、ＹＺ方向に広がる面を有する板状部材である。苗受け治具１３６の材質は、接ぎ木対象の苗の種類によって適宜選択することができる。例えば、苗が柔らかい場合には、樹脂やゴムなどの弾性部材とすることができ、苗が固い場合には、金属などとすることができる。また、例えば、苗がトマトである場合には、苗受け治具１３６として、表面にゴムシートを貼り付けた金属板を採用することができる。苗受け治具１３６は、Ｚ軸方向に延びる苗受け治具保持部２３４に保持されている。また、苗受け治具保持部２３４は、苗受け治具駆動機構１４４に接続されている。 The seedling receiving jig 136 is a plate-shaped member having a surface extending in the YZ direction. The material of the seedling receiving jig 136 can be appropriately selected depending on the type of seedling to be grafted. For example, when the seedling is soft, it can be made of an elastic member such as resin or rubber, and when the seedling is hard, it can be made of metal or the like. Further, for example, when the seedling is a tomato, a metal plate having a rubber sheet attached to the surface can be adopted as the seedling receiving jig 136. The seedling receiving jig 136 is held by the seedling receiving jig holding portion 234 extending in the Z-axis direction. Further, the seedling receiving jig holding portion 234 is connected to the seedling receiving jig driving mechanism 144.

苗受け治具駆動機構１４４は、モータやエアシリンダ等を有し、苗受け治具保持部２３４及び苗受け治具１３６をＹ軸方向（図５、図６の矢印Ｂ，Ｂ’方向）に移動させる。本実施形態では、苗受け治具駆動機構１４４により、苗受け治具１３６が図５の位置と図６の位置との間を往復移動する。なお、図５の位置は、回転テーブル２０が回転しても他の部材（例えば、上側把持機構２４や下側把持機構１２４、テープ引き出し機構３９など）と苗受け治具１３６が接触せず、苗受け治具１３６が回転テーブル２０の回転の邪魔にならない位置である。以下においては、図５の位置を「退避位置」と呼ぶものとする。また、図６の位置は、図１の３時の位置に存在する把持機構２４，１２４が保持する穂木及び台木を介して、切断刃１３８と対向する位置である。以下においては、図６の位置を「切断位置」と呼ぶものとする。 The seedling receiving jig drive mechanism 144 has a motor, an air cylinder, etc., and moves the seedling receiving jig holding portion 234 and the seedling receiving jig 136 in the Y-axis direction (directions of arrows B and B'in FIGS. 5 and 6). Move. In the present embodiment, the seedling receiving jig 136 moves back and forth between the position of FIG. 5 and the position of FIG. 6 by the seedling receiving jig drive mechanism 144. At the position of FIG. 5, even if the rotary table 20 rotates, other members (for example, the upper gripping mechanism 24, the lower gripping mechanism 124, the tape pulling mechanism 39, etc.) do not come into contact with the seedling receiving jig 136. The seedling receiving jig 136 is in a position where it does not interfere with the rotation of the rotary table 20. In the following, the position shown in FIG. 5 will be referred to as a “evacuation position”. Further, the position of FIG. 6 is a position facing the cutting blade 138 via the scion and the rootstock held by the gripping mechanisms 24 and 124 existing at the position of 3 o'clock in FIG. In the following, the position of FIG. 6 will be referred to as a “cutting position”.

（苗切断部１４による切断方法）
ここで、苗切断部１４による穂木１０２及び台木１０４の切断方法について説明する。なお、本実施形態では、「（Ａ）穂木・台木の供給」処理において、図６や図７（ａ）に示すように、穂木１０２の下端部が台木１０４の上端部よりも＋Ｙ側に位置するように供給されるものとする。なお、穂木１０２の下端部の台木１０４とＹ軸方向に関して隣接する部分が第１部分であり、台木１０４の上端部の穂木１０２とＹ軸方向に関して隣接する部分が第２部分である。本実施形態では、これら第１部分と第２部分が同一高さ位置において切断刃１３８により切断されるようになっている。 (Cut method by seedling cutting part 14)
Here, a method of cutting the scion 102 and the rootstock 104 by the seedling cutting portion 14 will be described. In the present embodiment, in the "(A) supply of scion / rootstock" process, as shown in FIGS. 6 and 7 (a), the lower end of the scion 102 is larger than the upper end of the rootstock 104. It shall be supplied so as to be located on the + Y side. The portion adjacent to the rootstock 104 at the lower end of the scion 102 in the Y-axis direction is the first portion, and the portion adjacent to the scion 102 at the upper end of the rootstock 104 in the Y-axis direction is the second portion. be. In the present embodiment, the first portion and the second portion are cut by the cutting blade 138 at the same height position.

まず、制御装置１０は、図６に示すように、穂木１０２及び台木１０４を把持する把持機構２４、１２４が３時の位置に移動してくるタイミングで、苗受け治具駆動機構１４４を駆動し、苗受け治具１３６を図５の退避位置から図６の切断位置まで移動させる。すなわち、苗受け治具１３６を、回転テーブル２０の回転の邪魔にならない位置から切断刃１３８と対向する位置まで移動させる。 First, as shown in FIG. 6, the control device 10 sets the seedling receiving jig drive mechanism 144 at the timing when the gripping mechanisms 24 and 124 that grip the scion 102 and the rootstock 104 move to the 3 o'clock position. It is driven to move the seedling receiving jig 136 from the retracted position in FIG. 5 to the cutting position in FIG. That is, the seedling receiving jig 136 is moved from a position that does not interfere with the rotation of the rotary table 20 to a position that faces the cutting blade 138.

次いで、制御装置１０は、切断刃駆動機構１４２を駆動し、切断刃１３８を矢印Ａ方向に移動させる。図８（ａ）は、切断刃１３８が穂木１０２及び台木１０４を切断した状態を＋Ｙ方向から見た状態を示す図であり、図８（ｂ）は、図８（ａ）の状態を概略的に示す斜視図である。図８（ａ）からわかるように、苗受け治具１３６は、穂木１０２及び台木１０４が切断刃１３８により切断されている間は、穂木１０２及び台木１０４が切断刃１３８に押されて−Ｘ方向に移動しないように押さえている。これにより、図８（ａ）に示すように、切断刃１３８により穂木１０２の茎部及び台木１０４の茎部を同時に、同一の高さ位置で切断することができる。この場合、穂木１０２と台木１０４の切断面は、Ｙ軸方向に対して平行かつＹＺ面に対して角度θ（θは例えば２０°〜３０°）をなす面となっている。ここで、本実施形態では、図１０に示すように、誘導部材１５０の刃部１３９と平行な面１５０ａは、刃部１３９よりも寸法ｍだけ穂木１０２及び台木１０４の方向に突き出た状態となっている。このため、本実施形態では、切断刃１３８及び誘導部材１５０が矢印Ａ方向（図８（ａ）、図８（ｂ）参照）に移動すると、穂木１０２の位置が刃部１３９の移動軌跡からわずかに＋Ｙ側にずれていても、図１０において破線円で示す部分が穂木１０２を−Ｙ側に誘導することができる。これにより、穂木１０２全体を刃部１３９により確実に切断できるようになっている。なお、上述のように誘導部材１５０の面１５０ａが刃部１３９よりも突き出ているが、穂木１０２及び台木１０４の切断の際には、図８（ｂ）に示すように、苗受け治具１３６と誘導部材１５０の−Ｘ側端部とは接触しないように、苗受け冶具１３６が位置決めされている。このため、切断の際に、切断刃１３８の刃部１３９と苗受け治具１３６の＋Ｘ面とを接触（当接）させることができる。なお、図８（ｂ）の場合に限らず、例えば、苗受け治具１３６のうち少なくとも誘導部材１５０と対向する箇所をスポンジ等の弾性部材で構成してもよい。このようにすることで、誘導部材１５０が苗受け治具１３６に接触した場合に苗受け治具１３６の一部（誘導部材１５０と接触した箇所）が凹むため、切断刃１３８の刃部１３９と苗受け治具１３６とを当接させることができる。 Next, the control device 10 drives the cutting blade driving mechanism 142 to move the cutting blade 138 in the direction of arrow A. FIG. 8 (a) is a diagram showing a state in which the cutting blade 138 cuts the scion 102 and the rootstock 104 as viewed from the + Y direction, and FIG. 8 (b) shows the state of FIG. 8 (a). It is a perspective view which shows schematicly. As can be seen from FIG. 8A, in the seedling receiving jig 136, the scion 102 and the rootstock 104 are pushed by the cutting blade 138 while the scion 102 and the rootstock 104 are being cut by the cutting blade 138. It is held down so that it does not move in the -X direction. As a result, as shown in FIG. 8A, the stem portion of the scion 102 and the stem portion of the rootstock 104 can be simultaneously cut at the same height position by the cutting blade 138. In this case, the cut surfaces of the scion 102 and the rootstock 104 are surfaces that are parallel to the Y-axis direction and have an angle θ (θ is, for example, 20 ° to 30 °) with respect to the YZ surface. Here, in the present embodiment, as shown in FIG. 10, the surface 150a of the guide member 150 parallel to the blade portion 139 protrudes in the direction of the scion 102 and the rootstock 104 by the dimension m from the blade portion 139. It has become. Therefore, in the present embodiment, when the cutting blade 138 and the guiding member 150 move in the direction of arrow A (see FIGS. 8A and 8B), the position of the scion 102 moves from the movement locus of the blade portion 139. Even if it is slightly deviated to the + Y side, the portion indicated by the broken line circle in FIG. 10 can guide the scion 102 to the −Y side. As a result, the entire scion 102 can be reliably cut by the blade portion 139. As described above, the surface 150a of the guiding member 150 protrudes from the blade portion 139, but when cutting the scion 102 and the rootstock 104, as shown in FIG. 8B, the seedling receiving treatment is performed. The seedling receiving jig 136 is positioned so that the tool 136 does not come into contact with the −X side end of the guide member 150. Therefore, at the time of cutting, the blade portion 139 of the cutting blade 138 and the + X surface of the seedling receiving jig 136 can be brought into contact (contact). Not limited to the case of FIG. 8B, for example, at least a portion of the seedling receiving jig 136 facing the guide member 150 may be formed of an elastic member such as a sponge. By doing so, when the guiding member 150 comes into contact with the seedling receiving jig 136, a part of the seedling receiving jig 136 (the part in contact with the guiding member 150) is dented, so that the cutting blade 138 has a blade portion 139. The seedling receiving jig 136 can be brought into contact with the seedling receiving jig 136.

この切断の間、穂木１０２の茎部は、図８（ｂ）に示すように段差部１３７ａに常に接触した状態となっている。したがって、穂木１０２は、切断刃１３８の矢印Ａ方向の移動に伴って、段差部１３７ａに沿って矢印Ｃ方向（−Ｙ方向）に誘導される。一方、台木１０４を把持する下側把持機構１２４においては、第１把持部材１２９Ａの上側の面（＋Ｚ面）に誘導部材１７０が設けられている。したがって、台木１０４の茎部が切断されると、台木１０４の茎部の軸の方向が鉛直方向と一致するように、台木１０４の茎部が誘導される。このような誘導により、穂木１０２の茎部の切断面と、台木１０４の茎部の切断面とが近づき合うため、各切断面の少なくとも一部同士を合わせることができる。 During this cutting, the stem of the scion 102 is in constant contact with the stepped portion 137a as shown in FIG. 8 (b). Therefore, the scion 102 is guided in the arrow C direction (−Y direction) along the step portion 137a as the cutting blade 138 moves in the arrow A direction. On the other hand, in the lower gripping mechanism 124 that grips the rootstock 104, the guiding member 170 is provided on the upper surface (+ Z surface) of the first gripping member 129A. Therefore, when the stem portion of the rootstock 104 is cut, the stem portion of the rootstock 104 is guided so that the direction of the axis of the stem portion of the rootstock 104 coincides with the vertical direction. By such guidance, the cut surface of the stem portion of the scion 102 and the cut surface of the stem portion of the rootstock 104 come close to each other, so that at least a part of each cut surface can be aligned with each other.

その後は、制御装置１０は、切断刃駆動機構１４２を駆動し、切断刃１３８を矢印Ａ’方向に移動させる。これにより、図９に示すように、穂木１０２の切断面の少なくとも一部と台木１０４の切断面の少なくとも一部が合わせられた状態になる。なお、本実施形態では、穂木１０２及び台木１０４を斜めに切断しているため、切断刃１３８の厚みにより穂木１０２の切断面と台木１０４の切断面の高さがわずかにずれたとしても、穂木１０２の切断面の少なくとも一部と台木１０４の切断面の少なくとも一部とを合わせることができる。なお、制御装置１０は、苗受け治具駆動機構１４４を駆動し、苗受け治具１３６を図５の位置まで移動させる。 After that, the control device 10 drives the cutting blade driving mechanism 142 to move the cutting blade 138 in the direction of arrow A'. As a result, as shown in FIG. 9, at least a part of the cut surface of the scion 102 and at least a part of the cut surface of the rootstock 104 are put together. In this embodiment, since the scion 102 and the rootstock 104 are cut diagonally, the heights of the cut surface of the scion 102 and the cut surface of the rootstock 104 are slightly deviated due to the thickness of the cutting blade 138. Even so, at least a part of the cut surface of the scion 102 and at least a part of the cut surface of the rootstock 104 can be combined. The control device 10 drives the seedling receiving jig drive mechanism 144 to move the seedling receiving jig 136 to the position shown in FIG.

なお、本発明者が装置を試作したところ、切断刃１３８とＹＺ面との間の角度θ（図７（ｂ）参照）を２０°〜３０°とした場合、段差部１３７ａの傾斜角度α（図７（ａ）参照）は、６０°〜８０°とするのが好ましいことが分かった。このような角度θ、αとすることで、穂木１０２及び台木１０４の切断と同時に、穂木１０２の茎部の切断面と台木１０４の茎部の切断面を互いに近づけ、合わせることが可能となり、従来のように穂木１０２の切断面と台木１０４の切断面とを合わせるための機構を用意しなくてもよくなることが分かった。 When the present inventor made a prototype of the apparatus, when the angle θ between the cutting blade 138 and the YZ surface (see FIG. 7B) is 20 ° to 30 °, the inclination angle α of the step portion 137a (see FIG. 7B) (see FIG. 7B). (See FIG. 7A), it was found that the temperature is preferably 60 ° to 80 °. By setting such angles θ and α, at the same time as cutting the scion 102 and the rootstock 104, the cut surface of the stem of the scion 102 and the cut surface of the stem of the rootstock 104 can be brought close to each other and aligned. It has become possible, and it has been found that it is not necessary to prepare a mechanism for aligning the cut surface of the scion 102 and the cut surface of the rootstock 104 as in the conventional case.

上述したように穂木１０２と台木１０４の切断が行われた後は、図１の６時の位置において、「（Ｃ）穂木１０２と台木１０４の接合」処理が行われる。この場合、回転テーブル２０の回転に伴って、不図示のテープ供給装置から供給されるテープ（熱可塑性テープ）をテープ引き出し機構３９が引き出し、引き出されたテープにより穂木１０２及び台木１０４の合わさった部分を挟む。そして、穂木１０２及び台木１０４の合わさった部分を挟んだテープを超音波溶着や熱溶着等することで、穂木１０２と台木１０４の接合を行う。なお、穂木１０２と台木１０４の接合方法としては、様々な方法を採用することができる。例えば、穂木１０２と台木１０４を粘着テープにより接合してもよい。また、穂木１０２と台木１０４をクリップや断面Ｃ字状の略筒状部材により接合してもよい。 After the scion 102 and the rootstock 104 are cut as described above, the "(C) grafting of the scion 102 and the rootstock 104" is performed at the position of 6 o'clock in FIG. In this case, as the rotary table 20 rotates, the tape pull-out mechanism 39 pulls out the tape (thermoplastic tape) supplied from the tape supply device (not shown), and the drawn tape is used to combine the scion 102 and the rootstock 104. Sandwich the part. Then, the scion 102 and the rootstock 104 are joined by ultrasonic welding, heat welding, or the like of the tape sandwiching the joined portion of the scion 102 and the rootstock 104. As a method of joining the scion 102 and the rootstock 104, various methods can be adopted. For example, the scion 102 and the rootstock 104 may be joined with an adhesive tape. Further, the scion 102 and the rootstock 104 may be joined by a clip or a substantially cylindrical member having a C-shaped cross section.

その後は、図１の７時の位置において、上側把持機構２４の力作用部３４、下側把持機構１２４の力作用部１３４の順に、トーションバネの付勢力に抗する力を付与することで、上側把持機構２４、下側把持機構１２４の順に把持を解除する。これにより、「（Ｄ）接合された苗の排出」処理が行われる。 After that, at the 7 o'clock position in FIG. 1, a force that opposes the urging force of the torsion spring is applied in the order of the force acting portion 34 of the upper gripping mechanism 24 and the force acting portion 134 of the lower gripping mechanism 124. The upper gripping mechanism 24 and the lower gripping mechanism 124 are released in this order. As a result, the process of "(D) discharging the joined seedlings" is performed.

なお、本実施形態では、切断刃１３８、苗受け治具１３６、及び切断刃駆動機構１４２等を含んで、穂木１０２の茎部及び台木１０４の茎部を同一高さで同時に切断する切断機構としての機能が実現されている。 In this embodiment, the cutting blade 138, the seedling receiving jig 136, the cutting blade driving mechanism 142, and the like are included to cut the stem of the scion 102 and the stem of the rootstock 104 at the same height at the same time. The function as a mechanism is realized.

以上、詳細に説明したように、本実施形態によると、上下に並ぶ上側把持機構２４及び下側把持機構１２４が穂木１０２及び台木１０４を把持し、切断刃１３８は、穂木１０２の茎部と台木１０４の茎部のＹ軸方向に関して隣接する部分を同一高さで同時に切断する。そして、誘導部材１５０は、切断刃１３８による切断と同時に、切断刃１３８の移動に応じて、穂木１０２の茎部を台木１０４側（−Ｙ側）に誘導する。これにより、本実施形態では、穂木１０２の茎部と台木１０４の茎部を同一高さにおいて切断すると同時に、穂木１０２の茎部を台木１０４側に移動させることで、穂木１０２の切断面の少なくとも一部と台木１０４の切断面の少なくとも一部とを合わせやすくすることができる。したがって、穂木１０２と台木１０４を上下動させるなどして穂木１０２の切断面の少なくとも一部と台木１０４の切断面の少なくとも一部とを合わせるための機構を用意する必要がない。このため、コストの低減を図ることができるとともに、切断面を合わせるための処理が不要になるため、「（Ｂ）穂木・台木の切断」処理に要する時間を削減することが可能となる。また、穂木１０２と台木１０４を１つの切断刃１３８で切断しているので、穂木１０２と台木１０４の切断面の角度を一致させることができるとともに、穂木１０２と台木１０４が同一軸上で保持されているため、切断面の向きを一致させることができる。これにより、接ぎ木苗における活着率を向上することができる。 As described in detail above, according to the present embodiment, the upper gripping mechanism 24 and the lower gripping mechanism 124 arranged one above the other grip the scion 102 and the rootstock 104, and the cutting blade 138 is the stem of the scion 102. The part and the part adjacent to the stem part of the rootstock 104 in the Y-axis direction are cut at the same height at the same time. Then, at the same time as cutting by the cutting blade 138, the guiding member 150 guides the stem portion of the scion 102 to the rootstock 104 side (−Y side) according to the movement of the cutting blade 138. As a result, in the present embodiment, the stem of the scion 102 and the stem of the rootstock 104 are cut at the same height, and at the same time, the stem of the scion 102 is moved to the rootstock 104 side, thereby causing the scion 102. It is possible to easily align at least a part of the cut surface of the rootstock 104 with at least a part of the cut surface of the rootstock 104. Therefore, it is not necessary to prepare a mechanism for aligning at least a part of the cut surface of the scion 102 with at least a part of the cut surface of the rootstock 104 by moving the scion 102 and the rootstock 104 up and down. For this reason, it is possible to reduce the cost and it is possible to reduce the time required for the "(B) cutting of scion / rootstock" process because the process for aligning the cut surfaces is not required. .. Further, since the scion 102 and the rootstock 104 are cut by one cutting blade 138, the angles of the cut surfaces of the scion 102 and the rootstock 104 can be matched, and the scion 102 and the rootstock 104 can be matched. Since they are held on the same axis, the orientations of the cut surfaces can be matched. Thereby, the survival rate in the grafted seedlings can be improved.

また、本実施形態では、誘導部材１５０は、切断刃１３８に設けられ、切断刃１３８の移動に応じて、穂木１０２の茎部を台木１０４の方向（−Ｙ側）に押して、誘導する。これにより、簡易な構成で、切断刃１３８の動きと連動して、穂木１０２を台木１０４側に誘導することができる。 Further, in the present embodiment, the guiding member 150 is provided on the cutting blade 138, and the stem portion of the scion 102 is pushed in the direction of the rootstock 104 (-Y side) in response to the movement of the cutting blade 138 to guide the scion 102. .. As a result, the scion 102 can be guided to the rootstock 104 side in conjunction with the movement of the cutting blade 138 with a simple configuration.

また、本実施形態では、第１把持部材１２９Ａに誘導部材１７０が設けられ、台木１０４の茎部の切断後に台木１０４の茎部を穂木１０２側（＋Ｙ側）に誘導する。これにより、穂木１０２と台木１０４の両方を寄せるように誘導するため、穂木１０２と台木１０４の各切断面を合わせやすくなる。 Further, in the present embodiment, the guiding member 170 is provided on the first gripping member 129A, and after cutting the stem portion of the rootstock 104, the stem portion of the rootstock 104 is guided to the scion 102 side (+ Y side). As a result, both the scion 102 and the rootstock 104 are guided to be brought together, so that it becomes easy to align the cut surfaces of the scion 102 and the rootstock 104.

また、本実施形態では、把持機構２４，１２４が回転テーブル２０の外周部に設けられており、回転テーブル２０の回転により３時の位置に位置決めされた把持機構２４，１２４が保持する穂木１０２及び台木１０４を切断刃１３８が切断する。これにより、本実施形態では、回転テーブル２０の回転により３時の位置に順次位置決めされる穂木１０２及び台木１０４を切断することが可能である。 Further, in the present embodiment, the gripping mechanisms 24 and 124 are provided on the outer peripheral portion of the rotary table 20, and the scion 102 held by the gripping mechanisms 24 and 124 positioned at the 3 o'clock position by the rotation of the rotary table 20. And the rootstock 104 is cut by the cutting blade 138. Thereby, in the present embodiment, it is possible to cut the scion 102 and the rootstock 104 which are sequentially positioned at the 3 o'clock position by the rotation of the rotary table 20.

また、本実施形態の接ぎ木システム１００は、上述したような苗切断部１４と、苗切断部１４により切断され、切断面の少なくとも一部が合わせられた状態の穂木１０２と台木１０４を、テープで挟み、テープを溶着することで、合わせられた部分をテープで覆う苗接合部１１０とを備えている。この場合、苗切断部１４における穂木１０２と台木１０４の切断及び切断面を合わせるのに要する時間を短縮できるため、接ぎ木に要する時間を短縮することができる。また、苗切断部１４のコスト削減により、接ぎ木システム１００全体のコストを削減することも可能となる。 Further, in the grafting system 100 of the present embodiment, the seedling cutting portion 14 as described above and the scion 102 and the rootstock 104 in a state where at least a part of the cut surface is combined after being cut by the seedling cutting portion 14 are provided. It is provided with a seedling joining portion 110 that covers the combined portion with the tape by sandwiching the tape with the tape and welding the tape. In this case, the time required for cutting and aligning the cut surfaces of the scion 102 and the rootstock 104 in the seedling cutting portion 14 can be shortened, so that the time required for grafting can be shortened. Further, by reducing the cost of the seedling cutting portion 14, it is possible to reduce the cost of the entire grafting system 100.

なお、上記実施形態では、切断刃１３８により、穂木１０２及び台木１０４を同一高さで切断する場合について説明したが、これに限られるものではない。すなわち、例えば、切断刃１３８の刃部１３９の延びる方向をＹ軸に対して傾斜させ、穂木１０２と台木１０４の切断高さを異ならせてもよい。この場合、穂木１０２の切断高さが台木１０４の切断高さよりも、切断刃１３８の厚さ分だけ低くなるように傾斜角度を設定することで、穂木１０２の切断面と台木１０４の切断面との間に隙間を生じさせないように穂木１０２の切断面と台木１０４の切断面とを合わせる場合に、接触面積を広くすることが可能となる。 In the above embodiment, the case where the scion 102 and the rootstock 104 are cut at the same height by the cutting blade 138 has been described, but the present invention is not limited to this. That is, for example, the extending direction of the blade portion 139 of the cutting blade 138 may be inclined with respect to the Y axis, and the cutting heights of the scion 102 and the rootstock 104 may be different. In this case, the cutting surface of the scion 102 and the rootstock 104 are set by setting the inclination angle so that the cutting height of the scion 102 is lower than the cutting height of the rootstock 104 by the thickness of the cutting blade 138. When the cut surface of the scion 102 and the cut surface of the rootstock 104 are aligned so as not to generate a gap between the cut surface of the scion 102, the contact area can be widened.

なお、切断刃１３８と苗受け治具１３６とによる切断の際に、穂木１０２及び台木１０４の表皮が未切断になることを防止するため、切断刃１３８が苗受け治具１３６に当接した状態で、苗受け治具１３６をＹ軸方向に動かすようにしてもよい。また、上記実施形態では、苗受け治具１３６が平板状の部材（＋Ｘ側の面が平面）である場合について説明したが、これに限らず、例えば、苗受け治具１３６の＋Ｘ側の面のうち、切断刃１３８が対向する箇所にスリットや凹部を形成してもよい。 When cutting with the cutting blade 138 and the seedling receiving jig 136, the cutting blade 138 comes into contact with the seedling receiving jig 136 in order to prevent the skins of the scion 102 and the rootstock 104 from being uncut. In this state, the seedling receiving jig 136 may be moved in the Y-axis direction. Further, in the above embodiment, the case where the seedling receiving jig 136 is a flat plate-shaped member (the surface on the + X side is a flat surface) has been described, but the present invention is not limited to this, and for example, the surface of the seedling receiving jig 136 on the + X side. Of these, slits and recesses may be formed at locations where the cutting blades 138 face each other.

（穂木１０２の誘導部材に関する変形例）
なお、上記実施形態では、誘導部材１５０が切断刃１３８による穂木１０２及び台木１０４の切断と同時に、穂木１０２を台木１０４側に誘導する場合について説明したが、これに限られるものではない。すなわち、穂木１０２及び台木１０４を切断した後に、穂木１０２を台木１０４側に誘導することとしてもよい。この場合、誘導部材としては、図１１（ａ）に示すような形状の誘導部材１５０’を用いることができる。図１１（ａ）の誘導部材１５０’の場合、切断刃１３８が矢印Ａ方向に移動して穂木１０２及び台木１０４を切断している間は、誘導部材１５０’は、穂木１０２を−Ｙ側に誘導しない。一方、切断が完了した後も切断刃１３８及び誘導部材１５０’が矢印Ａ方向に移動することで、図１１（ａ）において太線で示す部分が穂木１０２を−Ｙ方向に誘導することができる。この場合、穂木１０２を切断した後に穂木１０２を誘導するため、切り落とした部分が誘導の邪魔にならず、抵抗なく穂木１０２を誘導することができる。 (Modification example of the guiding member of the scion 102)
In the above embodiment, the case where the guiding member 150 guides the scion 102 to the rootstock 104 side at the same time as cutting the scion 102 and the rootstock 104 by the cutting blade 138 has been described, but the present invention is not limited to this. No. That is, after cutting the scion 102 and the rootstock 104, the scion 102 may be guided to the rootstock 104 side. In this case, as the guiding member, a guiding member 150' having a shape as shown in FIG. 11A can be used. In the case of the guiding member 150'in FIG. 11A, while the cutting blade 138 moves in the direction of arrow A to cut the scion 102 and the rootstock 104, the guiding member 150'-cuts the scion 102. Do not guide to the Y side. On the other hand, even after the cutting is completed, the cutting blade 138 and the guiding member 150'move in the direction of arrow A, so that the portion shown by the thick line in FIG. 11A can guide the scion 102 in the −Y direction. .. In this case, since the scion 102 is guided after cutting the scion 102, the cut-off portion does not interfere with the guidance, and the scion 102 can be guided without resistance.

なお、図１１（ａ）の場合、切断が完了した後も切断刃１３８及び誘導部材１５０’が矢印Ａ方向に移動する必要があるため、苗受け治具１３６には、切断刃１３８や誘導部材１５０’が通過できるスリット１３６ａを設けておくことが好ましい。なお、スリット１３６ａを設けずに、苗受け治具１３６が−Ｘ側に移動できるようにし、苗受け治具１３６の移動により、切断完了後における切断刃１３８及び誘導部材１５０’の矢印Ａ方向への移動を許容するようにしてもよい。 In the case of FIG. 11A, since the cutting blade 138 and the guiding member 150'need to move in the direction of arrow A even after the cutting is completed, the seedling receiving jig 136 includes the cutting blade 138 and the guiding member. It is preferable to provide a slit 136a through which 150'can pass. The seedling receiving jig 136 can be moved to the −X side without providing the slit 136a, and by moving the seedling receiving jig 136, the cutting blade 138 and the guiding member 150'in the direction of arrow A after the cutting is completed. May be allowed to move.

なお、上記実施形態では、誘導部材が切断刃１３８とともに移動する場合について説明したが、これに限られるものではない。例えば、切断と同時に又は切断後に穂木１０２を−Ｙ側に誘導する機構として、図１２に示すような誘導機構２５０を採用することもできる。図１２の誘導機構２５０は、Ｌ字状の誘導部材３０２と、誘導部材３０２をＹ軸方向に往復移動させる駆動装置３０４と、を備える。制御装置１０は、切断と同時に穂木１０２を−Ｙ方向に誘導する場合には、切断刃１３８による切断開始に合わせて、駆動装置３０４を用いて誘導部材３０２を−Ｙ方向に駆動する。この駆動により、誘導部材３０２が穂木１０２を押すため、上記実施形態と同様、切断中に穂木１０２を−Ｙ方向に誘導できるようになっている。一方、切断後に穂木１０２を−Ｙ方向に誘導する場合には、制御装置１０は、切断刃１３８による切断終了後の所定タイミングにおいて、駆動装置３０４を用いて誘導部材３０２を−Ｙ方向に駆動する。この駆動により、誘導部材３０２が穂木１０２を押すため、切断後に穂木１０２を−Ｙ方向に誘導できるようになっている。このように、誘導という機能に特化した誘導機構２５０を用いることで、誘導を的確に行うことが可能である。 In the above embodiment, the case where the guide member moves together with the cutting blade 138 has been described, but the present invention is not limited to this. For example, as a mechanism for guiding the scion 102 to the −Y side at the same time as or after cutting, the guidance mechanism 250 as shown in FIG. 12 can be adopted. The guidance mechanism 250 of FIG. 12 includes an L-shaped guidance member 302 and a driving device 304 that reciprocates the guidance member 302 in the Y-axis direction. When the control device 10 guides the scion 102 in the −Y direction at the same time as cutting, the control device 10 drives the guiding member 302 in the −Y direction by using the drive device 304 at the start of cutting by the cutting blade 138. Since the guiding member 302 pushes the scion 102 by this drive, the scion 102 can be guided in the −Y direction during cutting as in the above embodiment. On the other hand, when guiding the scion 102 in the −Y direction after cutting, the control device 10 drives the guiding member 302 in the −Y direction using the drive device 304 at a predetermined timing after the cutting by the cutting blade 138 is completed. do. By this drive, the guiding member 302 pushes the scion 102, so that the scion 102 can be guided in the −Y direction after cutting. In this way, by using the guidance mechanism 250 specialized in the function of guidance, it is possible to accurately perform guidance.

なお、図１２においては、誘導部材３０２を駆動するために、駆動装置３０４を用意する場合について説明したが、これに限られるものではない。例えば、図１３に示すように、苗受け治具１３６に誘導部材３０２を固定するようにしてもよい。この場合、切断と同時に又は切断後に、苗受け治具１３６を−Ｙ側に移動させることで、図１２と同様の効果を発揮することができる。なお、切断前の苗受け治具１３６の移動の際、及び穂木１０２を誘導した後の苗受け治具１３６の移動の際には、穂木１０２や台木１０４と誘導部材３０２とが機械的に干渉しないように、苗受け治具１３６を移動させることが好ましい。 In addition, in FIG. 12, the case where the driving device 304 is prepared for driving the guiding member 302 has been described, but the present invention is not limited to this. For example, as shown in FIG. 13, the guide member 302 may be fixed to the seedling receiving jig 136. In this case, by moving the seedling receiving jig 136 to the −Y side at the same time as or after cutting, the same effect as in FIG. 12 can be exhibited. When the seedling receiving jig 136 is moved before cutting, and when the seedling receiving jig 136 is moved after guiding the scion 102, the scion 102, the rootstock 104, and the guiding member 302 are mechanical. It is preferable to move the seedling receiving jig 136 so as not to interfere with each other.

（台木１０４の誘導部材に関する変形例）
なお、上記実施形態において下側把持機構１２４の第１把持部材１２９Ａに設けられた誘導部材１７０は、スポンジやゴム、ばね、フェルトなどの弾性部材であってもよい。このように誘導部材１７０に弾性を持たせることで、誘導部材１７０との接触による台木１０４の損傷を抑制することができる。また、誘導部材１７０として弾性部材を用いることで、弾性部材の弾性力により、切断後の台木１０４（＋Ｙ方向に穂木１０２の存在がなくなった台木１０４）を＋Ｙ方向に誘導しやすくなる。なお、誘導部材１７０の全てが弾性部材でなくてもよく、台木１０４と接触する一部分のみが弾性部材であってもよい。 (Modification example of the guide member of the rootstock 104)
In the above embodiment, the guiding member 170 provided on the first gripping member 129A of the lower gripping mechanism 124 may be an elastic member such as a sponge, rubber, a spring, or felt. By giving the guiding member 170 elasticity in this way, it is possible to suppress damage to the rootstock 104 due to contact with the guiding member 170. Further, by using the elastic member as the guiding member 170, the elastic force of the elastic member makes it easier to guide the rootstock 104 after cutting (the rootstock 104 in which the scion 102 does not exist in the + Y direction) in the + Y direction. .. It should be noted that not all of the guide members 170 may be elastic members, and only a part of the guide member 170 that comes into contact with the rootstock 104 may be an elastic member.

なお、上記実施形態では、第１把持部材１２９Ａの上側の面（＋Ｚ面）に誘導部材１７０を設ける場合について説明したが、これに限らず、誘導部材１７０を設けずに、第１把持部材１２９Ａの高さ方向の寸法を、第２把持部材１２９Ｂよりも大きく（高く）することとしてもよい。これにより、上記実施形態と同様の効果を得ることができるとともに、部品点数を削減し、コスト低減を図ることができる。 In the above embodiment, the case where the guide member 170 is provided on the upper surface (+ Z surface) of the first grip member 129A has been described, but the present invention is not limited to this, and the first grip member 129A is not provided without the guide member 170. The dimension in the height direction of the second gripping member 129B may be made larger (higher) than that of the second gripping member 129B. As a result, the same effect as that of the above embodiment can be obtained, the number of parts can be reduced, and the cost can be reduced.

なお、上記実施形態では、台木１０４の茎部を＋Ｙ方向に誘導する（軸を矯正する）ための誘導部材１７０が、下側把持機構１２４の第１把持部材１２９Ａに設けられている場合について説明したが、これに限られるものではない。例えば、図１４に示すように、苗受け治具１３６の一部（＋Ｘ側の面）に誘導部材３１０を設けることとしてもよい。この場合、苗受け治具１３６の＋Ｙ側への移動により、誘導部材３１０と台木１０４を接触させることで、上記実施形態の誘導部材１７０と同様の効果を得ることができる。なお、図１４の例では、切断と同時に又は切断後に、苗受け治具１３６を＋Ｙ方向に移動してもよい。これにより、台木１０４を＋Ｙ方向に押し込むことができるため、台木１０４の＋Ｙ側への誘導をスムーズに行うことが可能となる。 In the above embodiment, the case where the guiding member 170 for guiding the stem portion of the rootstock 104 in the + Y direction (correcting the shaft) is provided on the first gripping member 129A of the lower gripping mechanism 124. I have explained, but it is not limited to this. For example, as shown in FIG. 14, the guide member 310 may be provided on a part (+ X side surface) of the seedling receiving jig 136. In this case, by moving the seedling receiving jig 136 to the + Y side, the guiding member 310 and the rootstock 104 are brought into contact with each other, so that the same effect as that of the guiding member 170 of the above embodiment can be obtained. In the example of FIG. 14, the seedling receiving jig 136 may be moved in the + Y direction at the same time as or after cutting. As a result, the rootstock 104 can be pushed in the + Y direction, so that the rootstock 104 can be smoothly guided to the + Y side.

なお、図１４の構成において、誘導部材３１０の高さ方向の位置を調整可能にするための調整機構を苗受け治具１３６に設けることとしてもよい。調整機構としては、例えば、誘導部材３１０をＺ軸方向にスライド自在に保持するスライド機構などとすることができる。このように、調整機構を苗受け治具１３６に設けることで、穂木１０２や台木１０４の太さや硬さを考慮して、誘導部材３１０の位置を適切な高さ位置（Ｚ位置）に調整することが可能である。 In the configuration of FIG. 14, the seedling receiving jig 136 may be provided with an adjusting mechanism for adjusting the position of the guiding member 310 in the height direction. The adjusting mechanism may be, for example, a slide mechanism for holding the guide member 310 so as to be slidable in the Z-axis direction. In this way, by providing the seedling receiving jig 136 with the adjusting mechanism, the position of the guide member 310 is set to an appropriate height position (Z position) in consideration of the thickness and hardness of the scion 102 and the rootstock 104. It is possible to adjust.

なお、誘導部材は、図１５に示すように、苗受け治具保持部２３４に設けることとしてもよい（符号「３２０」参照）。すなわち、誘導部材３２０を、苗受け治具１３６に対して間接的に設けることとしてもよい。この場合、穂木１０２及び台木１０４が切断刃１３８により切断されるときに、誘導部材３２０の＋Ｙ端部が台木１０４に接触するようにしておけば、上記実施形態や図１４と同様の効果を得ることができる。なお、この場合にも、切断と同時に又は切断後に、苗受け治具保持部２３４を＋Ｙ方向に移動してもよい。なお、図１４の場合と同様、苗受け治具保持部２３４に調整機構（誘導部材３２０をＺ軸方向にスライド自在に保持するスライド機構など）を設けることとしてもよい。なお、台木１０４を＋Ｙ側に誘導するために、苗受け治具１３６や苗受け治具保持部２３４とは別に、図１２と同様の誘導機構を用いることとしてもよい。 As shown in FIG. 15, the guide member may be provided in the seedling receiving jig holding portion 234 (see reference numeral “320”). That is, the guide member 320 may be indirectly provided to the seedling receiving jig 136. In this case, when the scion 102 and the rootstock 104 are cut by the cutting blade 138, if the + Y end of the guide member 320 is brought into contact with the rootstock 104, the same as in the above embodiment and FIG. The effect can be obtained. In this case as well, the seedling receiving jig holding portion 234 may be moved in the + Y direction at the same time as cutting or after cutting. As in the case of FIG. 14, the seedling receiving jig holding portion 234 may be provided with an adjusting mechanism (such as a slide mechanism for holding the guide member 320 so as to be slidable in the Z-axis direction). In order to guide the rootstock 104 to the + Y side, a guidance mechanism similar to that shown in FIG. 12 may be used separately from the seedling receiving jig 136 and the seedling receiving jig holding portion 234.

なお、台木１０４を＋Ｙ側に誘導するための誘導部材は、切断刃１３８に設けることとしてもよい。図１６（ａ）、図１６（ｂ）には、切断刃１３８に穂木１０２用の誘導部材１５０と台木１０４用の誘導部材４５０を設けた例が示されている。本例では、図１６（ａ）、図１６（ｂ）に示すように、切断刃１３８の表側かつ＋Ｙ側には、上記実施形態と同様、穂木１０２用の誘導部材１５０が設けられ、切断刃１３８の裏側かつ−Ｙ側には、台木１０４用の誘導部材４５０が設けられている。誘導部材４５０は、三角形状のシート部材であり、切断刃１３８に対して接着剤やねじ等により固定される。このような構成を採用することで、穂木１０２及び台木１０４の切断と同時に、穂木１０２が誘導部材１５０によって−Ｙ側に誘導され、台木１０４が誘導部材４５０によって＋Ｙ側に誘導されることになる。このようにしても、上記実施形態と同様の効果を得ることができる。 The guiding member for guiding the rootstock 104 to the + Y side may be provided on the cutting blade 138. 16 (a) and 16 (b) show an example in which the cutting blade 138 is provided with the guiding member 150 for the scion 102 and the guiding member 450 for the rootstock 104. In this example, as shown in FIGS. 16A and 16B, a guide member 150 for scion 102 is provided on the front side and the + Y side of the cutting blade 138 to cut the scion 102, as in the above embodiment. A guide member 450 for the rootstock 104 is provided on the back side and the −Y side of the blade 138. The guide member 450 is a triangular sheet member, and is fixed to the cutting blade 138 with an adhesive, screws, or the like. By adopting such a configuration, at the same time as cutting the scion 102 and the rootstock 104, the scion 102 is guided to the −Y side by the guiding member 150, and the rootstock 104 is guided to the + Y side by the guiding member 450. Will be. Even in this way, the same effect as that of the above embodiment can be obtained.

なお、図１１（ａ）、図１１（ｂ）の例において、図１６（ａ）、図１６（ｂ）と同様に、切断刃１３８に台木１０４用の誘導部材を設けることとしてもよい。具体的には、図１７（ａ）、図１７（ｂ）に示すように、切断刃１３８の表側かつ＋Ｙ側に穂木１０２用の誘導部材１５０’を設けるとともに、切断刃１３８の裏側かつ−Ｙ側に台木１０４用の誘導部材４５０’を設けることとしてもよい。このような構成を採用することで、穂木１０２及び台木１０４の切断後に、穂木１０２が誘導部材１５０’によって−Ｙ側に誘導され、台木１０４が誘導部材４５０’によって＋Ｙ側に誘導されることになる。 In the examples of FIGS. 11 (a) and 11 (b), the cutting blade 138 may be provided with a guide member for the rootstock 104, as in the case of FIGS. 16 (a) and 16 (b). Specifically, as shown in FIGS. 17 (a) and 17 (b), a guide member 150'for the scion 102 is provided on the front side and + Y side of the cutting blade 138, and the back side and-of the cutting blade 138. The guide member 450'for the rootstock 104 may be provided on the Y side. By adopting such a configuration, after cutting the scion 102 and the rootstock 104, the scion 102 is guided to the −Y side by the guiding member 150', and the rootstock 104 is guided to the + Y side by the guiding member 450'. Will be done.

なお、上記実施形態及び変形例では、穂木１０２の下端部が台木１０４の上端部よりも＋Ｙ側に位置するように供給される場合について説明したが、これに限らず、穂木１０２の下端部が台木１０４の上端部よりも−Ｙ側に位置するように供給されてもよい。この場合、切断刃１３８と誘導部材１５０の位置関係を反転したり、誘導部材１７０を下側把持機構１２４の第２把持部材１２９Ｂに設けるなど、穂木１０２と台木１０４の位置関係に合わせて、各部の配置を適宜変更すればよい。 In the above embodiment and the modified example, the case where the lower end portion of the scion 102 is supplied so as to be located on the + Y side of the upper end portion of the rootstock 104 has been described, but the present invention is not limited to this. The lower end portion may be supplied so as to be located on the −Y side of the upper end portion of the rootstock 104. In this case, the positional relationship between the cutting blade 138 and the guiding member 150 is reversed, or the guiding member 170 is provided on the second gripping member 129B of the lower gripping mechanism 124, so as to match the positional relationship between the scion 102 and the rootstock 104. , The arrangement of each part may be changed as appropriate.

なお、上記実施形態では、把持機構２４、１２４を回転テーブル２０に３０°間隔で配置する場合について説明したが、これに限らず、その他の角度間隔で把持機構２４、１２４を配置するようにしてもよい。この場合、回転テーブル駆動装置２２は、把持機構２４、１２４を配置した間隔（角度）だけ回転テーブル２０を回転すればよい。 In the above embodiment, the case where the gripping mechanisms 24 and 124 are arranged on the rotary table 20 at intervals of 30 ° has been described, but the present invention is not limited to this, and the gripping mechanisms 24 and 124 are arranged at other angular intervals. May be good. In this case, the rotary table driving device 22 may rotate the rotary table 20 by the interval (angle) at which the gripping mechanisms 24 and 124 are arranged.

なお、上記実施形態では、把持機構２４，１２４が回転テーブル２０に設けられた場合について説明したが、これに限らず、把持機構２４，１２４は、直線状に移動する移動機構（コンベア状の移動機構）に設けられてもよい。 In the above embodiment, the case where the gripping mechanisms 24 and 124 are provided on the rotary table 20 has been described, but the present invention is not limited to this, and the gripping mechanisms 24 and 124 are moving mechanisms (conveyor-like movements) that move linearly. It may be provided in the mechanism).
