Description

本発明は、竹を所要の長さに効率よく切断させる竹切断装置およびその方法に関する。   The present invention relates to a bamboo cutting apparatus and method for efficiently cutting bamboo into a required length.

竹はこれを竹炭とした場合にその大きな比表面積から吸臭、吸湿さらには洗浄機能に優れ、また、竹の素材自体を生かした伝統的な建物内装材や工芸品原料あるいは筍等の食品材料としても有用であることが知られている。ところで、例えば竹炭や竹酢液の製造工程において、竹は予め扱いやすい長さあるいは竹炭釜に効率的に詰め込める長さに切断する必要がある。竹のうちの真竹等の曲げ性が強く、食器、工芸品などの細工物に適した用途のある竹はともかく、孟宗竹等は節部分が極めて硬く、節間が短く、切り出した後の適宜長さごとの切断作業に大きな作業負担を強いられる。孟宗竹の所要間隔ごとの切断について、まず手引き鋸による方法があるが、労力が大きすぎて作業時間がかかり人件費がかかりすぎて事業化が困難である。手引き鋸の代わりにチェーン・ソーを用いる切断方法がある。これについては、孟宗竹は一般的な樹木と異なり肉厚のうち、特に表皮が硬く、通常、その切断に利用されるチェーン・ソーは１４〜１５箇所程度の使用（切断）で刃こぼれが激しくなり刃の切れ味が極端に悪くなる。そして、そのたびに刃の目立てを行うので切断作業効率が劣り、多くの作業時間と作業労力を費やすのが現実であった。   Bamboo has excellent odor absorption, moisture absorption and cleaning functions due to its large specific surface area when it is made of bamboo charcoal, and it is also used as a traditional building interior material, craft material, or food material such as firewood utilizing the bamboo material itself. Are also known to be useful. By the way, for example, in the manufacturing process of bamboo charcoal or bamboo vinegar, it is necessary to cut the bamboo into a length that is easy to handle in advance or a length that can be efficiently packed in a bamboo charcoal pot. Bamboo, such as true bamboo, has strong bendability and is suitable for work such as tableware and crafts. Soso bamboo has extremely hard joints, short internodes, and an appropriate length after cutting. A heavy work burden is imposed on the cutting work. First, there is a hand saw method for cutting the required intervals of Munetake bamboo, but it is difficult to commercialize due to too much labor, too much work time and labor costs. There is a cutting method using a chain saw instead of a hand saw. In this regard, Munetake is different from ordinary trees in that it has a particularly thick skin, and usually the chain saw used for cutting is severely spilled when it is used (cut) at around 14-15 locations. The sharpness of the blade becomes extremely bad. Further, since the blade is sharpened each time, the cutting work efficiency is inferior, and it is a reality that a lot of work time and work labor are expended.

これに対し、竹の切断効率を向上させる提案は少なく、特に竹が長手方向に大きな湾曲あるいは反りを生じている場合が多い点、孟宗竹のように節が硬くかつ節間長さが短いものがある点、比較的に細身で幹の部分と先端部分との直径が異なる点、等の竹特有のくせがあり、このために竹の効率の良い切断のための装置の出現を阻んでいた。従来この竹切断の機械化に対して丸鋸盤で竹切断を行うものがあった。ところが、この丸鋸盤による被切削物の切削時に切刃に摩擦熱が生じこれによって、台金を膨張させ切刃への歪発生、切削能力低下、加工精度劣化、異音発生等の問題を発生させる。これを解決しようとする提案が特開平１０−７１５２２号においてなされているが、切刃を支持する台金に同心円状の溝を形成させたに過ぎず、竹切断作業全体について、労力を軽減しつつ該竹切断効率自体を高効率に行わせるようにすることは困難であった。
特開平１０−７１５２２号（明細書の特許請求の範囲、段落番号００１１、図１、図６） On the other hand, there are few proposals to improve the cutting efficiency of bamboo, especially that bamboo has a large curvature or warp in the longitudinal direction, and there are those with hard nodes and short internode lengths, such as Munetake bamboo. At one point, there is a habit peculiar to bamboo such as being relatively thin and having different diameters between the trunk and the tip, and this has hindered the emergence of an apparatus for efficient cutting of bamboo. Conventionally, there has been a method of cutting bamboo with a circular saw machine in response to the mechanization of bamboo cutting. However, frictional heat is generated on the cutting edge when cutting the workpiece with this circular saw, which causes problems such as expansion of the base metal, generation of distortion to the cutting edge, reduction of cutting ability, deterioration of processing accuracy, generation of abnormal noise, etc. generate. A proposal to solve this is made in Japanese Patent Laid-Open No. 10-71522, but only a concentric groove is formed in the base metal supporting the cutting blade, which reduces the labor for the entire bamboo cutting operation. However, it has been difficult to make the bamboo cutting efficiency itself highly efficient.
Japanese Patent Laid-Open No. 10-71522 (Claims of the specification, paragraph number 0011, FIG. 1, FIG. 6)

である。 The present invention has been made in view of the above-described conventional problems. One object of the present invention is to provide a bamboo cutting apparatus and method that can cut many bamboos reliably in a short time without requiring labor. Is to provide. Another object of the present invention is to provide a bamboo cutting apparatus and method that can cut bamboo efficiently at low cost. Another object of the present invention is to provide a bamboo cutting apparatus and method for supplying raw bamboo continuously and producing a processed bamboo by cutting smoothly.

本発明は、上記の目的を達成するために、横回転軸１２に固定されて回転する1個または複数個のブレード１４と、回転するブレード１４に対して原竹１６をその長手軸線が横回転軸の軸線に対して平行移動するように送り供給する送り供給手段（１３）と、を有し、送り供給手段は原竹１６の両小口（１６１ａ、１６１ｂ）にそれぞれ脱着自在に接続される支軸手段（４２）を含み、支軸手段の支軸４６を介してブレード１４の切断円領域Ｕに原竹１６を供給しつつ所望長さに切断する竹切断装置１０から構成される。原竹の両小口に脱着させる支軸手段は例えば口径外部から把持、挟み付け解除自在に接続するものでもよいが、竹の繊維方向に穿刺部材を設けてこれらで穿刺離脱自在に穿刺する構成とすると構造が簡単で、保守、交換も容易となって有利である。支軸手段の支軸を用いて回転するブレード側に送る送り供給手段は、該支軸を転動自在に載置させる構成とするのが簡易な構造で実現し得る。例えば機枠の上端などを利用してもよく、また、別途誘導用のレール等を設置しても良い。案内ガイドを取り付けても良い。また、送り方向に向けて下がるスロープを設けておくと原竹を軽く転がるように押すだけでその上を転がって例えば他の送り位置や位置決め用のセット位置に誘導しうるから有利である。ブレード間の離隔位置で切断後の竹の切断長さ寸法を決定する。   In order to achieve the above object, the present invention achieves one or a plurality of blades 14 fixed to the horizontal rotation shaft 12 and rotating, and the longitudinal axis of the raw bamboo 16 with respect to the rotating blade 14 is rotated horizontally. Feed supply means (13) for feeding and feeding so as to move parallel to the axis of the shaft, and the feed supply means is detachably connected to both small ends (161a, 161b) of the raw bamboo 16 respectively. The bamboo cutting device 10 includes a shaft means (42), and cuts the raw bamboo 16 to a desired length while supplying the raw bamboo 16 to the cutting circle region U of the blade 14 via the support shaft 46 of the support shaft means. The supporting shaft means to be attached to and detached from both small ends of the original bamboo may be connected from the outside of the caliber so that it can be grasped and pinched and released, but the puncture member is provided in the direction of the bamboo fiber and puncture is performed so that the puncture can be removed. This is advantageous because the structure is simple and maintenance and replacement are easy. The feed supply means for feeding to the rotating blade side using the support shaft of the support shaft means can be realized with a simple structure in which the support shaft is mounted so as to be able to roll. For example, the upper end of the machine frame or the like may be used, or a guide rail or the like may be separately installed. A guide may be attached. In addition, it is advantageous to provide a slope that descends in the feed direction because the bamboo can be rolled and guided to another feed position or a set position for positioning, for example, by simply pushing the raw bamboo so that it rolls lightly. The cutting length dimension of the bamboo after cutting is determined at a separation position between the blades.

支軸を介して原竹を回転ブレード方向に送り供給する際、ブレード１４の切断円領域Ｕに対して下方側から上昇しつつ進入させるように原竹１６を送るようにするとよい。単に上に開く凹部に支軸を係止させる状態で保持してそのまま上昇させながら切断円領域に進入させることにより極めて簡単な構造で原竹を切断円領域中に配置させた状態でさらに竹自身の自転回転操作を行える。回転入力は手動でも良いが機械駆動により自動で行っても良い。   When the raw bamboo is fed in the direction of the rotating blade via the support shaft, the raw bamboo 16 may be fed so as to enter the cutting circle region U of the blade 14 while ascending from the lower side. The bamboo itself is placed in the cut circle area with a very simple structure by holding it in the recess that opens upward and holding it in the state of being lifted and entering the cut circle area while raising it as it is. Can rotate and rotate. The rotation input may be performed manually or automatically by mechanical drive.

A parallel feed holding portion 64 may be provided. By sending the raw bamboo to the blade cutting area after performing the width direction cutting positioning, an accurate cutting length can be ensured and reliable cutting can be performed.

The blade is fed so as to move parallel to the axis of the rotary shaft, and is moved forward and backward to the cutting circle region U of the raid 14 while rotating the raw bamboo itself arranged in the cutting circle region of the blade as necessary. The bamboo cutting method is characterized by cutting the bamboo into a desired length.

本発明は、横回転軸に固定されて回転する1個または複数個のブレードと、回転するブレードに対して原竹をその長手軸線が横回転軸の軸線に対して平行移動するように送り供給する送り供給手段と、を有し、送り供給手段は原竹の両小口にそれぞれ脱着自在に接続される支軸手段を含み、支軸手段の支軸を介してブレードの切断円領域に原竹を供給しつつ所望長さに切断する竹切断装置の構成であるから、竹自体に後付の支軸を取り付けてその後の回転ブレードへ向けた供給搬送を円滑に行えるとともに、竹の自転方向回転駆動を簡単な構成で実現し得る。また、簡単な構成で低コストで装置を製造しうる。   The present invention feeds and feeds one or more blades fixed to a horizontal rotation shaft and rotating the bamboo so that its longitudinal axis is parallel to the axis of the horizontal rotation shaft. Feed supply means, and the feed supply means includes support shaft means detachably connected to both ends of the raw bamboo, and the raw bamboo is cut into the cutting circle region of the blade via the support shaft of the support shaft means. Since the bamboo cutting device is configured to cut to the desired length while supplying the material, a support shaft attached to the bamboo itself can be attached to smoothly feed and feed the rotating blade, and the bamboo can rotate in the rotation direction. Driving can be realized with a simple configuration. In addition, the apparatus can be manufactured at a low cost with a simple configuration.

能となり手動操作等を行えて構造を簡単とし、また、低コストに資する。 In addition, by adopting a configuration in which the raw bamboo is sent so as to enter the blade cutting circle region while ascending from the lower side, it is sent in the blade cutting region, that is, in the cutting depth direction, and the bamboo itself is further rotated in this state. Rotation drive can be performed smoothly and without difficulty. In addition, it is possible to reliably position the cutting lateral width to the blade by laterally feeding the raw bamboo arranged horizontally and holding it in the middle, and then sending the raw bamboo so as to enter while rising. Feeding by rollover of the support shaft becomes possible, and manual operation can be performed to simplify the structure and contribute to low cost.

また、送り供給手段は、支軸手段の支軸を支持しつつブレードの切断円領域に向けて誘導させる誘導機構を含む構成とすることにより、支軸手段の支軸と協働して円滑に原竹をブレードの切断領域に送り供給することができる。また、丸棒等の支軸で原竹を支持するからその移動に際しては支軸を転動させて案内させるレール等で支持すればよく、例えば、機枠の外壁等を利用してその上に載置懸架させることにより安定した一定方向への原竹の送り移動を実現し得る。また、下がり傾斜状に誘導部を構成することにより、手動でも簡単にしかも確実にブレード側に向けて原竹を送り供給しうる。   Further, the feed supply means includes a guide mechanism that supports the support shaft of the support shaft means and guides it toward the cutting circle region of the blade, so that the feed supply means can smoothly cooperate with the support shaft of the support shaft means. Raw bamboo can be fed to the cutting area of the blade. In addition, since the original bamboo is supported by a support shaft such as a round bar, the support may be supported by a rail or the like that rolls and supports the support shaft. For example, the outer wall of the machine frame is used to support it. By placing and suspending it, it is possible to realize the feed movement of the raw bamboo in a stable and constant direction. In addition, by configuring the guiding portion in a downwardly inclined manner, the raw bamboo can be fed and supplied toward the blade side easily and surely even manually.

By having the configuration, it is possible to reliably feed the raw bamboo in the lateral feed and position the cutting lateral width to the blade, and to accurately feed the cutting area to the cutting area by the next blade.

By providing a driving means for swinging and driving the parallel feed holding portion side, a reliable lateral feed and cutting lateral width of the raw bamboo arranged horizontally is provided. While performing positioning, the blade can be fed to the cutting region while being lifted by the driving means while being held by the parallel feed holding portion.

Positioning protrusions are provided at a position with a width interval corresponding to the distance between the positioning protrusions when the raw bamboo is fed from the lateral feed supply side and held and converged to the parallel feed holding part. By adopting a configuration in which the width direction cutting positioning is performed so as to sandwich the part, for example, it is automatically performed by rolling the support shaft from the state where the raw bamboo is set long in the lateral direction and moving it to the parallel feed holding part. In addition, it is possible to perform cutting in the width direction with respect to the blade.

The bamboo cutting device of the present invention is a device that reliably cuts bamboo by rotating the raw bamboo in the cutting area according to the warp state of the bamboo while smoothly supplying the raw bamboo to the cutting area by the rotary blade. is there.

図１ないし図７は、本発明の実施形態に係る竹切断装置を示しており、図１において、竹切断装置１０は、横回転軸１２に固定されて軸回り方向に回転するブレード１４と、原竹１６を軸平行送りしつつブレードの切断領域に送る送り機構１３と、原竹に脱着自在に連結される支軸機構４２と、を備えている。図１、図２において、機枠１８の前後中間位置であって地上からある程度の高さ位置に横長の横回転軸１２が軸受部２０を介して回転自在に軸支されている。機枠１８の正面側Ｋには鋼板等からなる正面壁２２が設けられるとともに機枠１８の背面側Ｌには切断加工済みの加工竹１６Ａを収容する集積部２３が設けられている。   1 to 7 show a bamboo cutting device according to an embodiment of the present invention. In FIG. 1, the bamboo cutting device 10 includes a blade 14 that is fixed to a horizontal rotation shaft 12 and rotates around an axis. A feed mechanism 13 that feeds the raw bamboo 16 to the cutting region of the blade while being axially fed, and a spindle mechanism 42 that is detachably connected to the raw bamboo are provided. In FIG. 1 and FIG. 2, a horizontally long horizontal rotating shaft 12 is rotatably supported via a bearing portion 20 at a middle position in the front and rear of the machine casing 18 and at a certain height from the ground. A front wall 22 made of a steel plate or the like is provided on the front side K of the machine casing 18, and a stacking portion 23 is provided on the rear side L of the machine casing 18 to accommodate the cut processed bamboo 16A.

図２、図５に示すように機枠１８の前後中間位置に４個の脚板２４が立設されそれらの上端に共通に載置されて横方向に角鋼管等からなる支持梁２６が連結固定されている。さらに、この支持梁２６の上部であって例えば４個の脚板２４のそれぞれの取り付け位置に対応した支持梁の上部側に４個の上支持板２８が固定されている。上支持板２８の上部にはそれぞれ分割軸受カバー３０と該分割軸受カバーに支持された軸受３２とを含む軸受け部２０が設けられており、さらにこの軸受３２に軸支されて横方向に長く設けられた横回転軸１２が回転自在に支持されている。実施形態において、回転軸１２は例えば７メートル程度の１本の長尺の軸から形成されており、分割軸受けカバー３０の連結を解除して分割させることにより簡単に軸受部２０から離脱させ得るようになっている。そして、該回転軸１２にブレード１４が固定されている。   As shown in FIGS. 2 and 5, four leg plates 24 are erected at the front and rear intermediate positions of the machine frame 18, and are commonly mounted on the upper ends thereof, and support beams 26 made of square steel pipes are connected and fixed in the lateral direction. Has been. Further, the four upper support plates 28 are fixed to the upper side of the support beam 26 corresponding to the attachment positions of the four leg plates 24, for example. A bearing portion 20 including a split bearing cover 30 and a bearing 32 supported by the split bearing cover is provided at the upper portion of the upper support plate 28. Further, the bearing portion 20 is supported by the bearing 32 and provided long in the lateral direction. The horizontal rotation shaft 12 is rotatably supported. In the embodiment, the rotating shaft 12 is formed of one long shaft of about 7 meters, for example, and can be easily detached from the bearing portion 20 by releasing the connection of the divided bearing cover 30 and dividing it. It has become. A blade 14 is fixed to the rotary shaft 12.

実施形態において、横回転軸１２には９枚の円盤状丸鋸体からなるブレード１４がその中心部を回転軸１２が貫通するように連結固定されている。すなわち、ブレード１４は横回転軸１２に固定され横回転軸と一体回転しつつその際の円周上に形成された切刃による円形状の切断領域Uを形成させる。本実施形態において、例えば定尺６メートル程度の竹林から切り出された原竹を分割切断するようにしてあり、例えば６０ｃｍ間隔で設けた９枚のブレードで１０分割して一度に１０個の切断加工済み竹を製造する。分割数はこれに限定されず、例えば３分割、５分割、その他の複数分割構成としても良いし、ブレード間の間隔設定ひいては加工切断長さ寸法設定も任意に計画しうる。さらに、実施形態において、ブレード１４は例えば直径４０ｃｍ程度の直径のものに設定されている。円盤状のブレードの中心には回転軸及びその固定金具があり、例えば孟宗竹の最大口径（直径）を２５ｃｍとすると、軸平行状に竹を送りながらする切断については、全断面の同時切断（１度の軸平行送り動作で輪切り状に切断すること）は困難である。これに対し、例えば３０インチ（７６２ｍｍ）程度のブレードを計画すれば、直径２５０ｍｍの全断面同時切断は可能であるが、ブレードの単価に加えブレード半径による負荷トルクが大きくなり、さらにその高速回転時の消費電力量も膨大となる。ブレード１４はその円形板の中心部に横回転軸１２の挿通用の孔が設けられ、横回転軸１２にブレード１４が１個づつその挿通孔を挿通されブレードの両面から挟み付ける固定金具３４を介して所定の離隔間隔位置で固定されている。   In the embodiment, a blade 14 made of nine disc-shaped circular saw bodies is connected and fixed to the horizontal rotating shaft 12 so that the rotating shaft 12 passes through the center portion thereof. That is, the blade 14 is fixed to the horizontal rotation shaft 12 and rotates integrally with the horizontal rotation shaft, and forms a circular cutting region U by a cutting blade formed on the circumference at that time. In the present embodiment, for example, raw bamboo cut out from a bamboo forest having a fixed length of about 6 meters is divided and cut, for example, divided into 10 pieces by nine blades provided at intervals of 60 cm, and 10 pieces are cut at a time. Produces finished bamboo. The number of divisions is not limited to this. For example, it may be divided into three, five, or other plural divisions, and the interval setting between the blades and the machining cut length dimension may be arbitrarily planned. Further, in the embodiment, the blade 14 is set to have a diameter of about 40 cm, for example. At the center of the disk-shaped blade, there is a rotating shaft and its fixing bracket. For example, when the maximum diameter (diameter) of Munetake bamboo is 25 cm, all sections are cut simultaneously (1) It is difficult to cut into a ring shape by an axial parallel feed operation. On the other hand, if a blade of about 30 inches (762 mm), for example, is planned, simultaneous cutting of the entire cross-section with a diameter of 250 mm is possible. The amount of power consumption becomes enormous. The blade 14 is provided with a hole for insertion of the horizontal rotary shaft 12 at the center of the circular plate, and a fixing metal fitting 34 is inserted into the horizontal rotary shaft 12 one by one through the insertion hole and sandwiched from both sides of the blade.

揺動するように設けられている。 In FIG. 3, the support lever 66 is disposed closer to the blade installation side than the temporary table 74, and the side wall 7.
The tip is lowered and provided in a tilted manner via a pivotal support 68 provided at zero. The support lever 66 is provided with a parallel feed holding portion 64 at a tip end portion having a downward slope, and constitutes a part of guiding means for rotatably mounting a support shaft 46 connected to the raw bamboo on the upper surface. In the embodiment, the guided raw bamboo is once held by the parallel feed holding portion 64, and further, in that state, the parallel feed of the raw bamboo toward the cutting region is realized by a smooth arc-shaped motion around the pivot portion 68. That is, the support lever 66 is provided so as to swing the parallel feed holding portion 64 on the front end side so as to freely advance and retract toward the cutting circle region of the blade.

図２、７において、本実施形態ではこの支持レバー６６は、側面視厚板状で平面視杓文字
状の部材からなり、平面視で枢支部６８側に形成された小幅部７８と、小幅部７８に連続し
しだいにその横幅を拡大させた大幅部８０を含む帯状部８２を備えている。そして、支持レバー６６の上面となる帯状部８２上に原竹の小口１６１ａ、１６１ｂに連結した支軸４６が転動自在に載置され下がり傾斜部をブレード側に向けて自然に下降誘導される。この際、前記した基板５０と位置決め用突起５６との間の支軸部分を小幅部７８上に載置しておけば転動して下り下端側に支軸４６（原竹）が下降し、さらに平行送り保持部６４に保持された状態で位置を決められその状態あるいは横方向長さ位置関係でブレード１４により１度に１０本の切断加工竹が製造される。すなわち、支軸４６の位置決め用突起５６は、支持レバー６６の大幅部８０に対応する程度の基板５０からの幅間隔をあけた位置に設定される。これによって、原竹１６が横送り供給元側から送られて平行送り保持部６４に保持収束される際に位置決め突設部（５６）間に大幅部８０を挟みつけるようにして幅方向切断位置決めを行う。図３，８，９において、支持レバー６６の先端部の平行送り保持部６４は大幅部８０の平坦部から連続し上開きフック状に凹設された上開きフック８４から構成されている。支持レバー６６の平坦部に載置される支軸４６は、下降して上開きフック８４の凹部に円滑に落ち込むように形成されており、これによって、誘導機構から平行送り保持部６４への移行を円滑に行ない、同時に幅方向切断位置決めを行う。さらに、上開きフック８４の凹部に載置させただけで保持するから軸回転方向についてはフリーであり、よって、回転入力手段を介して容易にかつ簡単に回転させることができる。 2 and 7, in the present embodiment, the support lever 66 is formed of a thick plate-like member in a side view and a letter-like member in a plan view, and a narrow portion 78 formed on the pivot portion 68 side in a plan view, and a narrow portion. A belt-like portion 82 including a large portion 80 having a lateral width that is gradually increased in succession to 78 is provided. Then, the support shaft 46 connected to the small bamboo stems 161a and 161b is slidably mounted on the belt-like portion 82 which is the upper surface of the support lever 66, and is lowered and guided naturally toward the blade side. . At this time, if the support shaft portion between the substrate 50 and the positioning projection 56 is placed on the small width portion 78, it rolls and the support shaft 46 (raw bamboo) descends to the lower end side, Further, the position is determined while being held by the parallel feed holding portion 64, and 10 cutting bamboos are manufactured at a time by the blade 14 in that state or in the lateral length positional relationship. That is, the positioning projection 56 of the support shaft 46 is set at a position spaced apart from the substrate 50 by a degree corresponding to the large portion 80 of the support lever 66. As a result, when the raw bamboo 16 is fed from the lateral feed supply side and held and converged by the parallel feed holding portion 64, the width direction cutting positioning is performed such that the large portion 80 is sandwiched between the positioning projecting portions (56). I do. 3, 8, and 9, the parallel feed holding portion 64 at the distal end portion of the support lever 66 includes an upper opening hook 84 that is continuous from the flat portion of the large portion 80 and is recessed in the shape of an upper opening hook. The support shaft 46 placed on the flat portion of the support lever 66 is formed so as to descend and smoothly fall into the concave portion of the upper opening hook 84, thereby shifting from the guide mechanism to the parallel feed holding portion 64. Is performed smoothly, and at the same time, positioning in the width direction is performed. Further, since it is held only by being placed in the recess of the upper opening hook 84, the axial rotation direction is free, and therefore it can be easily and easily rotated via the rotation input means.

図３，８，９において、支持レバー６６の下端側には油圧シリンダ８６の伸縮ロッド８８の端部が枢着されている。油圧シリンダ８６は、支持レバーの平行送り保持部６４側を上下方向に揺動駆動させる駆動手段であり、伸縮ロッド８８の上下動に対応して保持部６４に保持した支軸４６を介して支持する原竹１６をブレードの切断円領域Ｕに入出させて切断を行わせる。図８，９において、伸縮ロッド８８の上端部と支持レバー６６との枢着部分には押しバネ部材８９が挿嵌されており、ブレード１４による切断時の振動を緩衝させる。支持レバーの傾斜下がり状態であり、かつ、平行送り保持部６４で支軸４６を保持した状態では回転するブレードに原竹が接触しないようにしておくのが良い。また、竹は幹部分と穂先部分とでは口径が異なるので、これらの点から、油圧シリンダ８６の高さは事前に原竹の口径の変化を統計し、ブレードとの当たり部分が一様となるような高さ位置に油圧シリンダの高さを調整するようにすると良い。なお、図示しないが支持レバー６６の枢支部６８回り回動を円滑にし、かつ、補強を行うために適宜当該円弧移動用の案内補強機構を設けると良い。   3, 8, and 9, the end of the telescopic rod 88 of the hydraulic cylinder 86 is pivotally attached to the lower end side of the support lever 66. The hydraulic cylinder 86 is a driving means that swings and drives the parallel feed holding portion 64 side of the support lever in the vertical direction, and is supported via the support shaft 46 held by the holding portion 64 corresponding to the vertical movement of the telescopic rod 88. The raw bamboo 16 to be cut into and out of the cutting circle region U of the blade is cut. In FIGS. 8 and 9, a push spring member 89 is inserted into a pivotal portion between the upper end portion of the telescopic rod 88 and the support lever 66, and the vibration at the time of cutting by the blade 14 is buffered. In a state where the support lever is tilted downward and the support shaft 46 is held by the parallel feed holding portion 64, it is preferable that the raw bamboo does not contact the rotating blade. In addition, since the diameter of bamboo differs between the stem portion and the tip portion of bamboo, the height of the hydraulic cylinder 86 statistics the change in the diameter of the raw bamboo beforehand, and the contact portion with the blade is uniform. It is preferable to adjust the height of the hydraulic cylinder to such a height position. Although not shown, a guide reinforcing mechanism for moving the arc may be provided as appropriate for smooth rotation of the support lever 66 around the pivotal support portion 68 and for reinforcement.

上記した支持レバー６６、支軸機構４２、油圧シリンダ８６は横長に配置した原竹の両側
に設けられている。図中９０は、コントロールボックスであり、操作レバー９２を操作することにより油圧シリンダ８６の駆動、停止等の操作を行わせる。コントロールボックス９０は、例えば左端側などのいずれか一方側にのみ設置されている。左右の油圧シリンダ８６は連通しており、左右連動して駆動される。 The support lever 66, the support shaft mechanism 42, and the hydraulic cylinder 86 described above are provided on both sides of the raw bamboo arranged horizontally. In the figure, reference numeral 90 denotes a control box, which operates the operation of the hydraulic cylinder 86 by operating the operation lever 92. The control box 90 is installed only on one side such as the left end side. The left and right hydraulic cylinders 86 communicate with each other and are driven in conjunction with the left and right.

には例えば重機等でブレードを取り付けた横回転軸１２全体を吊支するが、その際に円滑な取り外しあるいは、取り付けができる。また、図５に示すように機枠１８の内部側であって、ブレード１４の設置位置の下部側には緩衝用スロープ１００が正面側から背面側にかけて下り傾斜となるように設けてあり、切断後の竹１６Ａを自然に集積部２３に集積させるようにしている。また、この緩衝用スロープ１００の表面にはゴム等の弾性部材が張設してある。 Further, 94 is a hood standing upright from the machine casing 18, and 96 is a protective cover. The protective cover is positioned at a position d shifted from the vertical upper side of the lateral rotation shaft 12 pivotally supported by the bearing 32 to the back side. 94 is connected to hinges 94 so as to stand up and down. When the blade is sharpened or replaced, for example, the entire horizontal rotating shaft 12 to which the blade is attached is suspended by a heavy machine or the like, and at that time, smooth removal or attachment is possible. Further, as shown in FIG. 5, a buffering slope 100 is provided on the inner side of the machine casing 18 at the lower side of the installation position of the blade 14 so as to be inclined downward from the front side to the rear side. The later bamboo 16A is naturally accumulated in the accumulation unit 23. Further, an elastic member such as rubber is stretched on the surface of the buffering slope 100.

次に、図に基づいて実施形態の竹切断装置１０の作用について説明すると、駆動モータ３８を介して横回転軸12及びそれに固定された９枚の丸鋸状ブレード１４を同時に回転させる。クレーンやホイスト等で例えば６ｍ程度の長さに切断した原竹１６を仮置き台７４上に横長状に載置させる。この状態で支軸機構４２の脱着部４８の穿刺針５２を原竹１６の両小口１６１ａ，１６１ｂに工具等で打ち込み、原竹の軸心を延長させるように支軸４６を連結させる。この状態で、原竹の両端側に在る作業者は協同して原竹を転がし、突丘７６を乗り越えて支持レバー６６の上部に押しやると下がり斜面により自然に支軸４６が帯状部８２上を転動して下降し、ついには平行送り保持部６４の上向きフック８４の凹部中に係合して保持される。この際、下がり斜面を支軸４６が下降するときに支軸の位置決め用突起５６と基板５０との間隙部分の支軸が帯状部８２上に載置されるから、傾斜面を下降する際に自然に原竹のブレード位置に対する横幅方向の位置が決められ、大幅部８０の横幅が位置決め用突起５６と基板５０との間に挟まれて位置決めを行う。この状態でコントロールボックスの操作レバー９２を介して油圧シリンダ８６を駆動して支持レバー６６の平行送り保持部６４側を上昇駆動させると原竹全体を回転ブレードにより輪切り切断される方向に供給することとなり、これによって、設定された所望長さに原竹を切断させる。原竹の口径がブレードの半径あるいはそれ以上の時には油圧シリンダ８６の１回の上下動送りのみでは１度に切断することは困難であり、この様な場合には、ブレード１４の切断円領域Ｕ内に原竹の一部をせり出させて一部を切削させ、その状態で自在脱着部６２を介して取り付けた手動入力用ハンドル６０を低速で回転させることにより原竹を自転させ、これによって、完全にブレードによる切断を行える（図８参照）。このように、油圧シリンダの可動範囲θで、下から原竹を上昇させる際にブレードによる切り込み深さを設定するようにしているので、切り込み深さ方向への原竹の移動並びにそれに続く原竹の自転操作を極めて簡単な構造で、しかも円滑に、かつ無理なく行える。これによって、１本ごとに素性が異なる軸方向変形を伴う竹の複数同時切断を確実に行える。   Next, the operation of the bamboo cutting device 10 according to the embodiment will be described with reference to the drawings. The horizontal rotary shaft 12 and nine circular saw blades 14 fixed thereto are simultaneously rotated via a drive motor 38. The raw bamboo 16 cut into a length of, for example, about 6 m by a crane, a hoist or the like is placed on the temporary placement table 74 in a horizontally long shape. In this state, the puncture needle 52 of the attaching / detaching portion 48 of the support shaft mechanism 42 is driven into both the small openings 161a and 161b of the raw bamboo 16 with a tool or the like, and the support shaft 46 is connected so as to extend the axial center of the original bamboo. In this state, the workers on both sides of the original bamboo roll together to roll the original bamboo and push it over the hill 76 and push it onto the upper portion of the support lever 66. , And finally, it is engaged and held in the concave portion of the upward hook 84 of the parallel feed holding portion 64. At this time, since the support shaft in the gap portion between the support positioning projection 56 and the substrate 50 is placed on the belt-like portion 82 when the support shaft 46 is moved down the inclined surface, when the inclined surface is lowered. The position in the width direction with respect to the blade position of the raw bamboo is naturally determined, and the width of the large portion 80 is sandwiched between the positioning projection 56 and the substrate 50 for positioning. In this state, when the hydraulic cylinder 86 is driven via the control lever 92 of the control box and the parallel feed holding portion 64 side of the support lever 66 is driven upward, the whole bamboo is supplied in a direction in which the rotary blade is cut into a ring. Thus, the raw bamboo is cut to the set desired length. When the diameter of the raw bamboo is larger than or equal to the radius of the blade, it is difficult to cut at once with only one vertical movement of the hydraulic cylinder 86. In such a case, the cutting circle region U of the blade 14 is difficult to cut. A portion of the raw bamboo is protruded into the inner portion, and a portion of the raw bamboo is cut. In this state, the manual bamboo is rotated by rotating the handle 60 for manual input attached through the free attaching / detaching portion 62 at a low speed. The blade can be completely cut (see FIG. 8). In this way, the depth of cut by the blade is set when raising the raw bamboo from below within the movable range θ of the hydraulic cylinder, so that the movement of the raw bamboo in the direction of the cut depth and the subsequent raw bamboo Rotation operation can be performed smoothly and easily with an extremely simple structure. As a result, multiple simultaneous cuttings of bamboo with axial deformation with different features for each piece can be reliably performed.

以上のように、本発明の竹切断装置は、横回転軸１２に固定されて回転する1個または複数個のブレード１４に対して原竹１６を横回転軸の軸線に対して平行移動するように送り、
ブレード１４の切断円領域Ｕに進退移動させつつ必要に応じて該ブレード１４の切断円領域中に配置された原竹自体を回転させることにより原竹１６を所望長さに切断するので、堅くて長くしかも反りあるいは曲がりを有する個々の竹について確実にしかも高効率に切断を行える。特に竹の両端に支軸を脱着可能に一体的に取り付け、これを利用して原竹の横送りあるいは平行送りを行うので個体により大きく異なる口径、曲がり、堅さ等に柔軟に対応して送り、回転などの処理を有効に行える。さらに、原竹を下方から切断領域に向けて上昇するように進入移動させる際に切断させるから、原竹の切断領域への移動と、原竹自体の自転回動を無理なく簡単な構成で低コストに実現し得る。 As described above, the bamboo cutting device according to the present invention translates the raw bamboo 16 relative to the axis of the horizontal rotation shaft with respect to one or a plurality of blades 14 fixed to the horizontal rotation shaft 12 and rotating. To
The raw bamboo 16 is cut to a desired length by rotating the raw bamboo itself disposed in the cutting circle area of the blade 14 as necessary while moving forward and backward to the cutting circle area U of the blade 14. It is possible to reliably and efficiently cut individual bamboos that are long and warped or bent. In particular, the support shafts are attached to both ends of the bamboo so as to be detachable, and the raw bamboo is fed laterally or parallelly using this, so it can be fed flexibly according to the diameter, bend, hardness, etc., which varies greatly depending on the individual. , Processing such as rotation can be performed effectively. Furthermore, since the raw bamboo is cut when entering and moving so as to rise from below to the cutting area, the movement of the raw bamboo to the cutting area and the rotation of the original bamboo itself can be reduced with a simple structure without difficulty. Can be realized at cost.
