【０００１】
【発明の属する技術分野】
本発明は、主として木製廃材を切断せしめるさいに使用する廃材用切断装置に関する。
【０００２】
従来より、廃材の切断装置としては、出願人等が先に開示した金属製廃材などの切断装置（実公昭６３−４８３４０号公報、実公平６−４１７７６号公報、実公平７−５００９５号公報、特許第３０５６０６９号公報等参照）が知られている。
そして、かかる切断装置は、直線状とされた一対の固定刃と可動刃とが軸を介してスリ合せ自在に軸着されると共に、可動刃の基端部に流体圧シリンダが連結された基本構成よりなり、流体圧シリンダの作動により可動刃を固定刃にスリ合せて金属製廃材などを切断せしめるものとされている。
【０００３】
ところで、上述のごとく構成された従来例は、固定刃と可動刃とが各々直線状に形成されているから、物理的・機械的強度が大な金属製廃材を確実に切断せしめることが出来る反面、金属製廃材に比して物理的・機械的強度の劣る木製廃材を切断せしめるさいにはその性状に起因して確実なる切断がしずらいものである。
【０００４】
本発明は、かかる従来例の問題点を一挙に解決し、主として木製廃材を確実に切断せしめることが出来るのみならず、被切断物等を掴持して移動せしめることが出来る、廃材用切断装置を提供しようとするものである。
【０００５】
【課題を解決するための手段】
即ち、請求項１記載の発明は、ホルダ−１の先部に略湾曲状とされた両側一対の受片２が所定間隔をおいて並設され、該受片２間には略半円形状の可動刃４が嵌合自在に軸着され、該可動刃４はその弧状外周縁に沿って鋸歯状刃体６が形成され、可動刃４には流体圧シリンダ８が接続され、上記受片２の基端部には各々固定掴持片３が立設されると共に、該固定掴持片３に対応すべく可動刃４の背部に掴持部７が形成されてなることを特徴とする、廃材用切断装置を要旨とするものである。
【０００６】
そして、本発明のかかる廃材用切断装置は、両側の受片２に木製廃材などの被切断物Ａを横架状に保持せしめつつ、流体圧シリンダ８の作動により刃体６が鋸歯状とされた可動刃４を受片２間に嵌合せしめ、鋸歯状刃体６を被切断物Ａに食込ませてその逃げを防止せしめつつ確実に切断せしめることが出来るのみならず、流体圧シリンダ８の作動により可動刃４を介して掴持部７を固定掴持片３方向に可動せしめ、固定掴持片３との間に所要の被切断物Ａやその切断片などを掴持せしめることが出来るものである。
【０００７】
【発明の実施の形態】
以下に、本発明の実施例の形態を図面に示す一実施例に基づいて説明する。
図１及び図２は本発明の一実施例を示すもので、同図中、１は後記するパワ−ショベル１０の多関節ア−ム１１に取付け自在とされたホルダ−、２は該ホルダ−１の先部に所定間隔をおいて並列状に取付けられた両側一対の湾曲状受片、３は該両側の受片２に各々対向すべくその基端がわに一体に立設された湾曲状の固定掴持片である。４は両側受片２の中間部位に軸５を介して嵌合自在に軸着された略半円形状の可動刃、６は該可動刃４の弧状外周縁に沿って所定ピッチ毎に形成された鋸歯状の刃体、７は前記固定掴持片３に対向すべく該可動刃４の背部に切欠き形成された湾曲状の掴持部、８は可動刃４を可動せしめるべくその背部下端に取付け部材９を介して連結された油圧シリンダで、該油圧シリンダ８の基端部は受片２の基端部に枢着されている。その他、１０はパワ−ショベル、１１は該パワ−ショベル１０を構成する旋回・屈曲自在な多関節ア−ム、Ａは木製廃材などの被切断物を示す。
【０００８】
上述のごとく構成された切断装置は、図３に示すように、パワ−ショベル１０の多関節ア−ム１１先部に所要の取付け部材を介して取付け、所要の被切断物Ａを切断せしめる。
即ち、図４に示すように、油圧シリンダ８の作動により軸５を支点として可動刃４を開作動せしめ、両側の受片２間に被切断物Ａを横架状に保持せしめる。しかるのち、油圧シリンダ８の作動により刃体６が鋸歯状とされた可動刃４を閉作動せしめて受片２内に嵌合せしめ、鋸歯状刃体６を被切断物Ａに食込ませてその逃げを防止せしめつつ切断せしめる。このさい、被切断物Ａを受片２内に保持せしめつつ可動刃４により切断せしめるものであるから、木製廃材などの切断を常に確実に行なうことが出来る。
【０００９】
また、上述のごとく構成された切断装置は、被切断物Ａの切断のみならず、被切断物Ａやその切断片などを掴持せしめて移動せしめることが出来る。
即ち、図５に示すように、流体圧シリンダ８の作動により軸５を支点として可動刃４を閉作動せしめることにより掴持部７と固定掴持片３との間を拡開せしめる。しかるのち、被切断物Ａやその切断片などに固定掴持片３を当てがいつつ、油圧シリンダ８の作動により可動刃４を開作動せしめることにより掴持部７と固定掴持片３との間に掴持せしめ、所要の場所に移動せしめるものである。
【００１０】
なお、上記実施例において、可動刃４は油圧シリンダ８により作動せしめるものとされているが、エアシリンダなどの流体圧シリンダを採用してもよいものである。
【００１１】
【発明の効果】
請求項１記載の発明によれば以上の次第で、ホルダ−１の先部に略湾曲状とされた両側一対の受片２が所定間隔をおいて並設され、該受片２間には略半円形状の可動刃４が嵌合自在に軸着され、該可動刃４はその弧状外周縁に沿って鋸歯状刃体６が形成され、可動刃４には流体圧シリンダ８が接続され、上記受片２の基端部には各々固定掴持片３が立設されると共に、該固定掴持片３に対応すべく可動刃４の背部に掴持部７が形成されているから、両側の受片２間に被切断物Ａを横架状に保持せしめつつ、流体圧シリンダ８の作動により刃体６が鋸歯状とされた可動刃４を受片２内に嵌合せしめ、鋸歯状刃体６を被切断物Ａに食込ませてその逃げを防止せしめつつ確実に切断せしめることが出来るものであって、特に木製廃材などの被切断物Ａを確実に切断せしめることが出来るのみならず、流体圧シリンダ８の作動により可動刃４を介して掴持部７を可動せしめ、固定掴持片３との間に被切断物Ａやその切断片などを確実に掴持して所要の場所に移動せしめることが出来るものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a waste material cutting device mainly used for cutting wooden waste material.
[0002]
DESCRIPTION OF RELATED ART Conventionally, as a cutting | disconnection apparatus of a waste material, the cutting apparatus of the metal waste materials etc. which the applicant etc. previously disclosed (Japanese Utility Model Publication No. 63-48340, Japanese Utility Model Publication No. 6-41776, Japanese Utility Model Publication No. 7-50095), Japanese Patent No. 3056069 is known.
Such a cutting device has a basic configuration in which a pair of linear fixed blades and a movable blade are pivotally mounted on a shaft via a shaft, and a fluid pressure cylinder is connected to a base end of the movable blade. The movable blade is fitted to the fixed blade by the operation of the fluid pressure cylinder to cut metal waste material and the like.
[0003]
By the way, in the conventional example configured as described above, since the fixed blade and the movable blade are each formed in a straight line, physical and mechanical strength can reliably cut metal waste materials having large physical strength. However, it is difficult to reliably cut a wooden waste material having a lower physical and mechanical strength than a metal waste material due to its properties.
[0004]
SUMMARY OF THE INVENTION The present invention solves the problems of the conventional example at once, and not only can mainly cut wooden waste materials reliably, but also can grip and move an object to be cut, etc. It is intended to provide.
[0005]
[Means for Solving the Problems]
That is, according to the first aspect of the present invention, a pair of substantially curved receiving pieces 2 are arranged side by side at a predetermined interval at the tip of the holder 1, and a substantially semicircular shape is formed between the receiving pieces 2. the movable blade 4 is axially mounted freely fitting, movable blade 4 is formed serrated blade 6 along its arcuate peripheral edge, the fluid pressure cylinder 8 is connected to the variable moving blade 4, the A fixed gripping piece 3 is erected at the base end of the receiving piece 2, and a gripping portion 7 is formed on the back of the movable blade 4 to correspond to the fixed gripping piece 3. The gist of the present invention is a waste material cutting device.
[0006]
In the waste material cutting apparatus according to the present invention, the blade body 6 is formed into a saw-tooth shape by the operation of the fluid pressure cylinder 8 while the cut pieces A such as wooden waste materials are horizontally held by the receiving pieces 2 on both sides. Not only can the movable blade 4 be fitted between the receiving pieces 2 so that the saw-toothed blade body 6 can be cut into the workpiece A so as to prevent the escape thereof, and can be reliably cut. By moving the gripping portion 7 in the direction of the fixed gripping piece 3 via the movable blade 4, the required object A or the cut piece can be gripped between the gripping portion 7 and the fixed gripping piece 3. You can do it.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to an embodiment shown in the drawings.
FIGS. 1 and 2 show one embodiment of the present invention. In the drawings, reference numeral 1 denotes a holder which can be freely attached to a multi-joint arm 11 of a power shovel 10 described later, and 2 denotes the holder. A pair of curved receiving pieces 3 are attached to the front end of the base 1 in parallel at a predetermined distance, and the curved receiving pieces 3 have their base ends erected integrally to face the receiving pieces 2 on both sides. It is a fixed holding piece of a shape. Reference numeral 4 denotes a movable blade having a substantially semicircular shape which is rotatably fitted to an intermediate portion of the both-side receiving piece 2 via a shaft 5, and 6 is formed at a predetermined pitch along an arc-shaped outer peripheral edge of the movable blade 4. A saw-toothed blade body 7 is a curved gripping portion formed by notching a back portion of the movable blade 4 so as to face the fixed gripping piece 3, and 8 is a lower end of the back portion for moving the movable blade 4. The hydraulic cylinder 8 is connected via a mounting member 9 with a base end of the hydraulic cylinder 8 pivotally attached to a base end of the receiving piece 2. In addition, reference numeral 10 denotes a power shovel, 11 denotes a swivel / bendable articulated arm constituting the power shovel 10, and A denotes an object to be cut such as a wooden waste material.
[0008]

That is, as shown in FIG. 4, the movable blade 4 is opened with the shaft 5 as a fulcrum by the operation of the hydraulic cylinder 8, and the object A to be cut is horizontally held between the receiving pieces 2 on both sides. Accordingly Thereafter, the movable blade 4 to blade 6 is serrated by the operation of the hydraulic cylinder 8 brought closing operation tighten fit fit into receiving piece 2, thereby bite the serrated blade 6 object to be cut A Cutting is performed while preventing the escape . At this time, since the object to be cut A is cut by the movable blade 4 while being held in the receiving piece 2, it is possible to always reliably cut the wooden waste material and the like.
[0009]
In addition, the cutting device configured as described above can not only cut the object A, but also move the object A and its cut pieces by gripping them.
That is, as shown in FIG. 5, by operating the fluid pressure cylinder 8, the movable blade 4 is closed with the shaft 5 as a fulcrum, so that the space between the gripping portion 7 and the fixed gripping piece 3 is expanded. Thereafter, the movable blade 4 is opened by the operation of the hydraulic cylinder 8 while the fixed gripping piece 3 is applied to the object A or the cut piece thereof, so that the gripping portion 7 and the fixed gripping piece 3 are connected. They can be grasped in between and moved to the required location.
[0010]
In the above embodiment, the movable blade 4 is operated by the hydraulic cylinder 8, but a hydraulic cylinder such as an air cylinder may be employed.
