Description
本考案は、金属等の硬質材を切断する切断装置に関するものである。 The present invention relates to a cutting device for cutting a hard material such as metal.
金属スクラップには、板状のものや、線状のものがある。金属スクラップは細かく裁断した後に、不純物を取り除いて精製される。裁断に利用される切断装置として、円周上に刃を配置した回転刃が利用されている。例えば、被覆電線のリサイクル化の処理過程で使用される回転刃として、特許文献1には、電線くずを破砕する回転刃と固定刃により、銅線と被覆部とを被覆電線を細かく切断する剥離粉砕機が示されている。また、櫛刃と、この櫛刃の間を回転する回転刃を有する粗切り機も示されている。特許文献２には、金属を切断するものではないが、被覆電線から分離された覆部は円柱形の回転刃により寸断する切断装置が開示されている。 Metal scrap includes plate-like and linear ones. After scraping metal scrap, it is refined by removing impurities. As a cutting device used for cutting, a rotary blade having a blade arranged on a circumference is used. For example, as a rotary blade used in the process of recycling coated electric wires, Patent Document 1 describes that a copper blade and a coated portion are separated into fine pieces by cutting a copper wire and a covered portion with a rotary blade and a fixed blade that crush electric wire scraps. A grinder is shown. A rough cutting machine having a comb blade and a rotating blade rotating between the comb blades is also shown. Patent Document 2 discloses a cutting device that does not cut metal, but cuts the cover portion separated from the covered electric wire with a cylindrical rotary blade.
金属スクラップを切断する際には、回転刃と固定刃とが互いに摺り合わせが悪いと金属スクラップを噛み込んで、うまく切断が行えない。また、回転刃を再生する際には研ぎが行われるが、特許文献１に開示された剥離粉砕機のように刃が円周上の配置されている場合は、外周側から研ぎを行うと刃が後退して固定刃との摺り合わせの間隔が空いてしまう。また、粗切り機の櫛刃の間を回転する回転刃は、その研磨自体が難しい。 When cutting the metal scrap, if the rotating blade and the fixed blade do not slide each other, the metal scrap is caught and cutting cannot be performed well. Further, when the rotary blade is regenerated, sharpening is performed. However, when the blade is arranged on the circumference like the peeling crusher disclosed in Patent Document 1, if the sharpening is performed from the outer peripheral side, the blade Retreats, and there is a gap in sliding with the fixed blade. In addition, it is difficult to polish the rotary blade rotating between the comb blades of the roughing machine.
本考案は、回転刃と固定刃とが互いに摺り合わせが良く、回転刃を容易に再生することを可能とする切断装置を提供することを目的とする。 An object of the present invention is to provide a cutting device in which a rotary blade and a fixed blade are slid well with each other and the rotary blade can be easily regenerated.
上記課題を解決するため、本考案は、内部中空の内周面が雌テーパ面であり、雌テーパ面へ被切断物を案内する供給孔出口に固定刃が形成された支承ブロックと、前記支承ブロックの雌テーパ面内で回転する中空の回転体であって、当該回転体は、前記供給孔の雌テーパ面を摺動する雄テーパ面の外周面を持ち、前記供給孔に対向する位置には前記外周面から内部中空に通じる透孔が形成され、該透孔の周壁部の半径方向最外箇所で回転方向後側となる部分に切刃が形成され、且つ内部中空は外部に開口していることを特徴とする。 In order to solve the above-described problems, the present invention provides a support block in which a hollow inner peripheral surface is a female tapered surface, and a fixed blade is formed at a supply hole outlet for guiding an object to be cut to the female tapered surface; A hollow rotating body that rotates within the female taper surface of the block, the rotating body having an outer peripheral surface of a male taper surface that slides on the female taper surface of the supply hole, at a position facing the supply hole. Is formed with a through hole communicating with the inner hollow from the outer peripheral surface, a cutting edge is formed at the outermost radial portion of the peripheral wall portion of the through hole on the rear side in the rotation direction, and the inner hollow opens to the outside. It is characterized by.
本考案によれば、回転体の外周面の刃面が雄テーパ上にあり、回転体が支承ブロックの雌テーパ面に包囲されているため、噛み込みにより固定刃と切刃の間隔が開くことが抑制される。また、回転体は、研磨されると後退するものとなるが、雌テーパ面に対して雄テーパ面の位置をずらせば、固定刃との摺り合わせの間隔を容易に調整できるという効果がある。 According to the present invention, since the blade surface of the outer peripheral surface of the rotating body is on the male taper and the rotating body is surrounded by the female taper surface of the support block, the gap between the fixed blade and the cutting blade is widened by biting. Is suppressed. In addition, the rotating body moves backward when polished, but if the position of the male taper surface is shifted with respect to the female taper surface, there is an effect that the interval of sliding with the fixed blade can be easily adjusted.
以下、図面を参照して本考案の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図１は、実施例の切断装置１００を被覆電線切断する被覆電線処理装置１に適用した例である。切断装置１００は、前処理装置１０１から供給される被覆電線を、輪切り状に裁断する。切断装置１００を構成する支承ブロック２１、回転体２２について、図２を参照して説明する。 FIG. 1 is an example in which the cutting device 100 of the embodiment is applied to a coated wire processing device 1 that cuts a coated wire.

The outlet portion on the inner peripheral surface 21a side of the supply hole 26 is a fixed blade 26a.
回転体２２は、図２Ｂに示すように、円錐状の雄テーパ面とされた外周面２２ａを有している。外周面２２ａは内周面２１ａに対応する傾斜を持つテーパ面であり、内周面２１ａ内に挿入される。回転体２２は、前端３０ａから後端３０ｂにかけて中空であり、前端３０ａ側が外部に向けて開口して排出穴３０を形成されている。 As shown in FIG. 2B, the rotating body 22 has an outer peripheral surface 22a that is a conical male tapered surface. The outer peripheral surface 22a is a tapered surface having an inclination corresponding to the inner peripheral surface 21a, and is inserted into the inner peripheral surface 21a. The rotating body 22 is hollow from the front end 30a to the rear end 30b, and the front end 30a side opens toward the outside to form a discharge hole 30.
回転体２２の外周面２２ａを形成した雄テーパ面の長さ途中で供給孔２６に対向する位置には外周面２２ａから排出穴３０内に通じる透孔３１が形成されており、透孔３１の移動軌跡の範囲内に、供給孔２６の出口開口が正対する。透孔３１の周壁部の半径方向最外箇所で回転方向後側となる部分には切刃３２が形成されている。この切刃３２は回転体２２の回転方向ｅにほぼ直交した刃縁を有する。 A through hole 31 communicating from the outer peripheral surface 22a into the discharge hole 30 is formed at a position facing the supply hole 26 in the middle of the length of the male tapered surface forming the outer peripheral surface 22a of the rotating body 22. The outlet opening of the supply hole 26 faces in the range of the movement locus. A cutting blade 32 is formed in a portion that is the rear side in the rotation direction at the radially outermost portion of the peripheral wall portion of the through hole 31. The cutting blade 32 has a blade edge substantially orthogonal to the rotation direction e of the rotating body 22.
上記した支承ブロック２１と回転体２２において、内周面２１ａと回転体２２の外周面２２ａとは何れも硬質の金属材料などで形成されている。 In the support block 21 and the rotating body 22 described above, the inner peripheral surface 21a and the outer peripheral surface 22a of the rotating body 22 are both formed of a hard metal material or the like.
また、支承ブロック２１と回転体２２には互いの位置関係の調節機構として、支承ブロック２１には等角度間隔に調節棒挿入孔２７が、回転体２２には外周溝２８が設けられているが、これについては後術する。 The support block 21 and the rotating body 22 are provided with adjusting rod insertion holes 27 at equal angular intervals, and the rotating body 22 is provided with an outer peripheral groove 28 as an adjustment mechanism for the positional relationship between the support block 21 and the rotating body 22. This will be done later.
図１に戻り、前処理装置１０１は、送込ローラ部２、一対の切断部３、４及び送出ローラ部５を備えている。送込ローラ部２は、下部駆動ローラ６と上部ローラ７とからなっている。下部駆動ローラ６は定位置で回転されるもので、外周面には被覆電線などの被切断物ｗを案内する比較的浅くて扁平な案内溝６ａが形成されて、この案内溝６ａと上部ローラ７の外周面とで形成された空間部に被覆電線を挟持する。一方、上部ローラ６は回転自在且つ上下変位可能に支持されると共に弾力を介して下方へ付勢された状態とされており、下部駆動ローラ６に対し上下変位することで径が大小に異なる被切断物ｗに対応できるようになっている。切断部３は上部回転刃８と線材案内部９からなっており、また送り方向ａの下手側（前側）の切断部４は下部回転刃１０と線材案内ローラ１１からなっている。 Returning to FIG. 1, the pretreatment device 101 includes a feeding roller unit 2, a pair of cutting units 3 and 4, and a feeding roller unit 5. The feeding roller unit 2 includes a lower driving roller 6 and an upper roller 7. The lower drive roller 6 is rotated at a fixed position, and a relatively shallow and flat guide groove 6a for guiding a workpiece w such as a covered electric wire is formed on the outer peripheral surface. The guide groove 6a and the upper roller A covered electric wire is held in a space formed by the outer peripheral surface of 7. On the other hand, the upper roller 6 is supported so as to be rotatable and vertically displaceable, and is urged downward through elasticity, and is displaced vertically with respect to the lower drive roller 6 so that the diameter varies depending on the size. It can respond to the cut object w. The cutting part 3 is composed of an upper rotary blade 8 and a wire guide 9, and the cutting part 4 on the lower side (front side) in the feed direction a is composed of a lower rotary blade 10 and a wire guide roller 11.
切断部３において、上部回転刃８は外周縁が先鋭状の円板体であり、矢印方向ｂへ回転駆動されると共に弾力で下方へ付勢された状態の下で上下変位可能に支持されている。一方、線材案内部９はその上面に案内溝９ａを形成されている。この案内溝９ａは下部駆動ローラ６のそれよりも深い略Ｖ字状に形成されており、この案内溝９ａ内の幅中央に上部回転刃８の外周縁が進入した状態となっている。上部回転刃８は案内溝９ａ上に位置した被切断物ｗを切り込む。 In the cutting part 3, the upper rotary blade 8 is a disc body having a sharp outer peripheral edge, and is supported so as to be vertically displaceable under a state of being rotationally driven in the arrow direction b and being urged downward by elasticity. Yes. On the other hand, the guide rod 9 has a guide groove 9a formed on the upper surface thereof. The guide groove 9a is formed in a substantially V shape deeper than that of the lower drive roller 6, and the outer peripheral edge of the upper rotary blade 8 enters the center of the width in the guide groove 9a. The upper rotary blade 8 cuts the workpiece w positioned on the guide groove 9a.
切断部４において、下部回転刃１０は外周縁が先鋭状とされた円板体であることは上部回転刃８と変わりないが、定位置にて矢印方向ｃへ回転駆動されるようになっている。一方、線材案内ローラ１１は弾力で下方へ付勢された状態の下で上下変位可能に支持されている。この線材案内ローラ１１の外周面に先の案内溝９ａと同様な深い略Ｖ字形の案内溝１１ａが形成されており、この案内溝１１ａ内の幅中央に下部回転刃１０の外周縁が進入された状態となっている。下部回転刃１０はこの案内溝１１ａ内に位置した被切断物ｗを切り込む。 In the cutting part 4, the lower rotary blade 10 is a disc having a sharp outer peripheral edge, which is the same as the upper rotary blade 8, but is rotationally driven in the arrow direction c at a fixed position. Yes. On the other hand, the wire guide roller 11 is supported so as to be vertically displaceable under a state where it is biased downward by elasticity. A deep substantially V-shaped guide groove 11a similar to the previous guide groove 9a is formed on the outer peripheral surface of the wire guide roller 11, and the outer peripheral edge of the lower rotary blade 10 enters the center of the width in the guide groove 11a. It is in the state. The lower rotary blade 10 cuts the workpiece w positioned in the guide groove 11a.
切断装置１００は、回転体２２を駆動手段２３により回転される。駆動装置２３は、支承ブロック２１の後面２１ｃに固定された減速機構３３ａ付の電動モータ３３と、サーボモータ３３の制御手段３５からなる。減速機構３３ａを介した回転伝動軸３４は回転体２２の後端中心部に結合されており、軸方向（図上、左右方向）に動くことが可能となっている。 In the cutting device 100, the rotating body 22 is rotated by the driving means 23. The drive device 23 includes an electric motor 33 with a speed reduction mechanism 33 a fixed to the rear surface 21 c of the support block 21 and a control means 35 of the servo motor 33. The rotation transmission shaft 34 via the speed reduction mechanism 33a is coupled to the center of the rear end of the rotating body 22, and can move in the axial direction (left and right in the figure).
調節機構２９は、回転伝動軸３４の回転を許容した状態でこの回転伝動軸３４に軸方向の位置を決めるものであり、調節棒挿入孔２７と外周溝２８と調節棒１３とにより構成され、支承ブロック２１と回転体２２との互いの位置関係を調整する。調節棒は、外周溝２８に勘合する頭頂円柱部１３ａと、挿入孔２７に勘合する基底円柱部１３ｂを有している。頭頂円柱部１３ａは、基底円柱部１３ｂの頂上部に変心した状態で設けられている。外周溝２８の溝幅は、調節棒挿入孔２７の内径より大きなものとなっており、回転体２２が初期の状態においては、調節棒挿入孔２７を覗いたときに後端側２５ｃ寄りに外周溝２８が覗けるように配置されている。調節棒１３を挿入孔２７に勘合すると、先端の頭頂円柱部１３ａは、外周溝２８に勘合する。調節棒１３を挿入孔２７内で回転することにより、回転体２２と支承ブロック２１の相対位置が変化し、外周面２２ａと内周面２１ａの間隔を調整することができる。回転体２２を研磨して外周面２２ａが後退しても、外周面２２ａを内周面２１ａに押し込むことにより、雄／雌テーパー面の勘合状態は変わらない。よって、調節棒１３を挿入孔２７内で回転することにより、透孔３１の周壁部の半径方向最外箇所で回転方向後側となる部分の切刃３２ａと供給孔２６の内周面２１ａ側出口部の固定刃２６ａとの間隔が調整される。調整機構２９は、これとは別の形態をとることも可能であり、例えば、支承ブロック２１を移動させたり、駆動手段自体を移動させたりする。 The adjustment mechanism 29 determines the axial position of the rotation transmission shaft 34 in a state where the rotation of the rotation transmission shaft 34 is allowed. The adjustment mechanism 29 includes an adjustment rod insertion hole 27, an outer peripheral groove 28, and the adjustment rod 13. The positional relationship between the support block 21 and the rotating body 22 is adjusted. The adjustment bar has a top columnar portion 13 a that fits into the outer circumferential groove 28 and a base columnar portion 13 b that fits into the insertion hole 27. The top columnar portion 13a is provided in a state of being eccentric to the top of the base columnar portion 13b. The groove width of the outer peripheral groove 28 is larger than the inner diameter of the adjusting rod insertion hole 27. When the rotating body 22 is in the initial state, the outer periphery is closer to the rear end side 25c when looking into the adjusting rod insertion hole 27. It arrange | positions so that the groove | channel 28 can be seen. When the adjustment rod 13 is fitted into the insertion hole 27, the top crown column portion 13 a is fitted into the outer circumferential groove 28. By rotating the adjusting rod 13 within the insertion hole 27, the relative position of the rotating body 22 and the support block 21 changes, and the distance between the outer peripheral surface 22a and the inner peripheral surface 21a can be adjusted. Even if the rotating body 22 is polished and the outer peripheral surface 22a is retracted, the mating state of the male / female tapered surface is not changed by pushing the outer peripheral surface 22a into the inner peripheral surface 21a. Therefore, by rotating the adjusting rod 13 in the insertion hole 27, the cutting blade 32 a at the rear side in the rotation direction at the radially outermost portion of the peripheral wall portion of the through hole 31 and the inner peripheral surface 21 a side of the supply hole 26. The distance between the outlet portion and the fixed blade 26a is adjusted. The adjustment mechanism 29 can take another form. For example, the adjustment mechanism 29 moves the support block 21 or moves the driving means itself.
尚、一般的に内面の研磨は難しいとされているが、仮にこれを行う場合でも、支承ブロック２１の固定刃２６ａを研磨した場合も、同様に切刃３２ａと固定刃２６ａの間隔を調整できる。尚、固定刃２６ａは鈍角となるので、切刃３２ａよりは破損しにくい。 Although it is generally difficult to polish the inner surface, even if this is performed, the interval between the cutting blade 32a and the fixed blade 26a can be adjusted similarly when the fixed blade 26a of the support block 21 is polished. . Since the fixed blade 26a has an obtuse angle, it is less likely to break than the cutting blade 32a.
潤滑剤供給手段２４は潤滑油源３６と、通路３７とを介して支承ブロック１の内周面２１ａと回転体２２の外周面２２ａと間に潤滑油を圧送して、内周面２１ａと外周面２２ａとの間の摺動を円滑にする。支承ブロック２１の後端側２５ｃには、Ｏリング１４が設けられており、潤滑油の飛散を抑止する。 The lubricant supply means 24 pumps the lubricating oil between the inner peripheral surface 21 a of the support block 1 and the outer peripheral surface 22 a of the rotating body 22 via the lubricant source 36 and the passage 37, so that the inner peripheral surface 21 a and the outer peripheral surface Smooth sliding between the surface 22a. An O-ring 14 is provided on the rear end side 25c of the support block 21 to suppress the scattering of the lubricating oil.
次に上記した切断装置の使用例及び作用を説明する。
被覆電線ｗは図３Ａに示すように環状の被覆部ｗ１と、この被覆部ｗ１で覆われた銅線ｗ２とからなっている。この被覆電線ｗの先端を前処理装置１０１の送込ローラ部２に差し込む。これにより被覆電線ｗは下部駆動ローラ６の案内溝６ａと上部ローラ７に挟まれて下部駆動ローラ６から送り力を付与され送り方向へ移動される。
Next, the usage example and effect | action of an above-described cutting device are demonstrated.
As shown in FIG. 3A, the covered electric wire w includes an annular covering portion w1 and a copper wire w2 covered with the covering portion w1. The tip of the covered electric wire w is inserted into the feeding roller portion 2 of the pretreatment device 101. As a result, the covered wire w is sandwiched between the guide groove 6a of the lower drive roller 6 and the upper roller 7, is applied with a feed force from the lower drive roller 6, and is moved in the feed direction.
被覆電線ｗが切断部３の上部回転刃８の下方に到達したとき、上部回転刃８の外周縁が被覆電線ｗの被覆部ｗ１の上下向きの直径の上端箇所にその回転力で切り込むように作用し、以後、被覆部ｗ１はこれの縦向きの直径面に沿ってその上部を連続的に切り離される。この後、被覆電線ｗが切断部４の下部回転刃１０の上方に到達したとき、線材案内ローラ１１の案内溝１１ａに案内され下部回転刃１０の外周縁がその被覆部ｗ１の上下向きの直径の下端箇所にその回転力で切り込む。こうして前処理装置１０１を通過後の被覆電線ｗは、図３Ｂに示すように外周の複数個所（電線直径上の位置ｆ１、ｆ１）において、被覆部ｗ１を長さ方向に沿って切り離された状態となる。 When the covered electric wire w reaches below the upper rotary blade 8 of the cutting portion 3, the outer peripheral edge of the upper rotary blade 8 is cut into the upper end portion of the diameter of the covered portion w1 of the covered electric wire w by the rotational force. Thereafter, the upper portion of the covering portion w1 is continuously cut along its longitudinal diameter surface. Thereafter, when the covered electric wire w reaches the upper part of the lower rotary blade 10 of the cutting part 4, the outer peripheral edge of the lower rotary blade 10 guided by the guide groove 11a of the wire guide roller 11 has a diameter in the vertical direction of the cover part w1. Cut at the lower end of the plate with that rotational force. Thus, the covered wire w after passing through the pretreatment device 101 is in a state where the covered portion w1 is cut along the length direction at a plurality of positions (positions f1, f1 on the wire diameter) on the outer periphery as shown in FIG. 3B. It becomes.
この後、被覆電線ｗは、切断装置１００の供給孔２６内に供給される。切断装置１００では、回転体２２がモータ３３により内周面２１ａと同心状態で回転された状態である。被覆電線ｗの先部は供給孔２６と透孔３１とが正対する間に、一定長さ（例えば２０ｍｍ）だけ排出穴３０内に挿入された状態となり、固定刃２６ａと切刃３２とによる切断作用で横断方向へ切断される。回転体２２の外周面２２ａの刃面が雄テーパ上にあり、回転体２２が支承ブロック２１の雌テーパ面に包囲されているため、噛み込みにより固定刃２６ａと切刃３２ａの間隔が開くことが抑制される。 Thereafter, the covered electric wire w is supplied into the supply hole 26 of the cutting device 100. In the cutting device 100, the rotating body 22 is rotated by the motor 33 in a concentric state with the inner peripheral surface 21a. The tip of the covered electric wire w is inserted into the discharge hole 30 by a certain length (for example, 20 mm) while the supply hole 26 and the through hole 31 face each other, and is cut by the fixed blade 26a and the cutting blade 32. It is cut in the transverse direction by the action. Since the blade surface of the outer peripheral surface 22a of the rotator 22 is on the male taper and the rotator 22 is surrounded by the female taper surface of the support block 21, the gap between the fixed blade 26a and the cutting blade 32a is increased by biting. Is suppressed.
上記実施例においては、切断装置１００は回転体２２の中心線を水平としたが、鉛直に配置しても良い。また、被覆電線を切断対象としたが、アルミ缶、鉄缶を切断対象として、これらを輪切り状に切断しても良い。この場合、供給孔２６、透孔３１は、被切断物の大きさに応じたものを使用する必要がある。上記実施例においては、供給孔２６および透孔３１は、Ｕ字形状のものを示したが、断面円、楕円、長円或いは多角形状の孔でもよい。また、金属棒等を切断対象とすることもできる。さらに、回転体２２の後端側３０ｂに駆動手段３３を配置したが、前側３０ａに駆動手段３３を配置してもよい。また、切刃３２の刃縁は、回転体２２の回転方向ｅにほぼ直交したものとしたが、斜めとすることも可能である。 In the embodiment described above, the cutting device 100 has the center line of the rotating body 22 horizontal, but it may be arranged vertically. Moreover, although covered electric wire was made into the cutting object, you may cut | disconnect these in a ring shape by making aluminum can and an iron can into cutting object. In this case, it is necessary to use the supply hole 26 and the through-hole 31 according to the size of the object to be cut. In the above embodiment, the supply hole 26 and the through hole 31 are U-shaped, but a cross-sectional circle, an ellipse, an ellipse, or a polygonal hole may be used. Further, a metal rod or the like can be a cutting target. Furthermore, although the drive unit 33 is disposed on the rear end side 30b of the rotating body 22, the drive unit 33 may be disposed on the front side 30a. Moreover, although the blade edge of the cutting blade 32 is substantially perpendicular to the rotation direction e of the rotating body 22, it can also be inclined.
