Description

本発明は、超音波切断装置におけるホーンへのカッター刃の固定方法に関するものである。   The present invention relates to a method for fixing a cutter blade to a horn in an ultrasonic cutting apparatus.

ホーンの超音波振動によりその先端に固定したカッター刃をもって種々の切断対象物を切断する超音波切断装置が広く用いられている。   2. Description of the Related Art An ultrasonic cutting device that cuts various cutting objects with a cutter blade fixed to the tip thereof by ultrasonic vibration of a horn is widely used.

そして、斯かる超音波切断装置においてそのカッター刃は消耗品であり、短い周期で頻繁に交換しなければならない。また、このカッター刃の交換には一々装置の稼働を停止しなければならないから、交換作業を迅速に行わなければならない。   In such an ultrasonic cutting apparatus, the cutter blade is a consumable item and must be frequently replaced in a short cycle. In addition, since the operation of the apparatus must be stopped for exchanging the cutter blade, the exchanging work must be performed quickly.

このため、従来においても超音波切断装置におけるホーンへのカッター刃の固定方法として、例えば特許文献１に示された如きものが案出されている。   For this reason, conventionally, as a method for fixing the cutter blade to the horn in the ultrasonic cutting device, for example, the one shown in Patent Document 1 has been devised.

それは図１０乃至図１４に示す通りであり、ホーン１００に、その先端面に中心部に向かって深くなるテーパー状の傾斜面１０１を設けると共に、該傾斜面１０１から奥の方にホーン１００の軸に沿った雌ネジ１０２を刻設した孔１０２Ａを設ける一方、前記ホーン１００と別体で、ホーン１００の前記雌ネジ１０２を刻設した孔１０２Ａに螺入するボルト１０３における頭部１０３ａを、その雌ネジ１０２を刻設した孔１０２Ａとの螺合側の面を前記傾斜面１０１と同等のテーパー状の傾斜面１０４となすと共に、頭部１０３ａの端面にホーン１００の軸に沿ったカッター刃挿入溝１０５を設け、該カッター刃挿入溝１０５にカッター刃１０６を挿入した状態で前記ボルト１０３を前記ホーン１００の雌ネジ１０２を刻設した孔１０２Ａ内に螺進させ、前記ホーン１００の傾斜面１０１と前記ボルト１０３の傾斜面１０４との共働によってボルト１０３のカッター刃挿入溝１０５を狭め、もって該ボルト１０３のカッター刃挿入溝１０５によってカッター刃１０６を把持するものである。   This is as shown in FIGS. 10 to 14, and the horn 100 is provided with a tapered inclined surface 101 deeper toward the center at the tip surface thereof, and the axis of the horn 100 is provided at the back from the inclined surface 101. Is provided with a hole 102A engraved with a female screw 102 along the head, and a head 103a of a bolt 103 screwed into the hole 102A provided with the female screw 102 of the horn 100 separately from the horn 100. The surface on the screwing side with the hole 102A in which the female screw 102 is engraved is formed into a tapered inclined surface 104 equivalent to the inclined surface 101, and a cutter blade is inserted into the end surface of the head 103a along the axis of the horn 100. A groove 105 is provided, and the bolt 103 is inserted into the cutter blade insertion groove 105 in the hole 102A in which the female screw 102 of the horn 100 is cut. The cutter blade insertion groove 105 of the bolt 103 is narrowed by the cooperative action of the inclined surface 101 of the horn 100 and the inclined surface 104 of the bolt 103, and the cutter blade 106 is thereby moved by the cutter blade insertion groove 105 of the bolt 103. To grip.

特開２０１０−５９１号公報JP 2010-591 A

斯かる従来方法によれば、切れ味の悪くなったカッター刃を迅速に新しいカッター刃と交換することができる。しかしまた一方で、実際に使用している上で次の如き改善すべき問題点のあることも判明した。   According to such a conventional method, it is possible to quickly replace a cutter blade having a poor sharpness with a new cutter blade. However, on the other hand, it has been found that there are the following problems to be improved in actual use.

先ず、第１の改善すべき問題点は、ボルト１０３のカッター刃挿入溝１０５の挟持によるカッター刃１０６の把持力が弱い点である。即ち、ボルト１０３の螺進につれてカッター刃挿入溝１０５の対向壁は徐々に狭められるが、それは図１３に示す如く、カッター刃挿入溝１０５の対向壁１０５ａ、１０５ａにおける切口側（開放端）の部分Ｐ、Ｐからカッター刃１０６への接触が始まるから、両対向壁１０５ａ、１０５ａは平行にならず、カッター刃１０６に対しては面ではなく点或いは線で接触していることになる。このため把持力が弱く、振動中にカッター刃１０６の抜け落ちを招く虞があった。そしてまた、これが超音波振幅を上げられない原因ともなっていた。そしてまた、一旦カッター刃１０６の抜け落ちが発生するとカッター刃挿入溝１０５の対向壁１０５ａ、１０５ａに焼きつき等が起こり、高い摩擦係数を維持することができなくなる。そしてこの場合においては再組み付けをしても摩擦係数の低下によりカッター刃１０６が抜け落ち易く、そして対向壁１０５ａ、１０５ａの面の修正を行おうとすると嵌め合い校差が大きくならざるを得ず、初期状態に戻すことはできない。   First, the first problem to be improved is that the gripping force of the cutter blade 106 due to the clamping of the cutter blade insertion groove 105 of the bolt 103 is weak. That is, as the bolt 103 is screwed, the opposing wall of the cutter blade insertion groove 105 is gradually narrowed. As shown in FIG. 13, this is a portion on the cut side (open end) of the opposing walls 105a and 105a of the cutter blade insertion groove 105. Since the contact from P and P to the cutter blade 106 begins, the opposing walls 105a and 105a are not parallel, and the cutter blade 106 is in contact with a point or line instead of a surface. For this reason, the gripping force is weak, and the cutter blade 106 may fall off during vibration. In addition, this is also the cause of the inability to increase the ultrasonic amplitude. Further, once the cutter blade 106 falls off, the opposing walls 105a and 105a of the cutter blade insertion groove 105 are seized and the high friction coefficient cannot be maintained. In this case, the cutter blade 106 is likely to fall off due to a decrease in the coefficient of friction even if reassembly is performed, and if the surface of the opposing walls 105a and 105a is to be corrected, the fitting gap must be increased. It cannot be returned to the state.

また、第２の改善すべき問題点は、ボルト１０３をねじ回すことによってカッター刃１０６を把持するものであるから、カッター刃１０６のホーン１００の円周方向に対する位置の再現性に問題があるということである。即ち、図１４に示す如く、カッター刃の交換の度毎にホーン１００に対するカッター刃１０６の回転方向の位置がずれるということである。この場合には改めてホーン或いは切断部材の位置を再セットし直さなければならず、その分余計な手間と時間を要していた。   Further, the second problem to be improved is that the cutter blade 106 is gripped by screwing the bolt 103, so that there is a problem in the reproducibility of the position of the cutter blade 106 in the circumferential direction of the horn 100. That is. That is, as shown in FIG. 14, the position of the cutter blade 106 in the rotational direction is shifted with respect to the horn 100 every time the cutter blade is replaced. In this case, it is necessary to reset the position of the horn or the cutting member again, which requires extra labor and time.

本発明は上記の点に鑑みなされたものであって、ホーンの先端面に、ホーンの中心部において最も深くなる三角形状の切り込みを設け、該三角形状の切り込みの各平坦な傾斜面に夫々、各傾斜面にホーンの軸と平行に螺装したネジの螺進をもって該傾斜面に沿って接離方向に摺動する一対の挟持駒を取り付け、該一対の挟持駒の平坦な対向壁間にカッター刃を挟持固定するようになし、もって上記従来方法の問題点を悉く解消することができるようになした超音波切断装置におけるホーンへのカッター刃の固定方法を提供しようとするものである。   The present invention has been made in view of the above points, and provided on the front end surface of the horn a triangular cut that is deepest in the center of the horn, and each flat inclined surface of the triangular cut, A pair of clamping pieces that slide in the approaching and separating direction along the inclined surface is attached to each inclined surface by screwing of a screw threaded parallel to the axis of the horn, and a cutter is provided between the flat opposing walls of the pair of holding pieces. It is an object of the present invention to provide a method for fixing a cutter blade to a horn in an ultrasonic cutting apparatus that is capable of pinching and fixing the blade and thus resolving the problems of the conventional method.

而して、本発明の要旨とするところは、ホーンの先端面に、ホーンの中心部において最も深くなる三角形状の切り込みを設け、該三角形状の切り込みの各平坦な傾斜面に夫々、各傾斜面にホーンの軸と平行に螺装したネジの螺進をもって該傾斜面に沿って接離方向に摺動する一対の挟持駒を取り付け、該一対の挟持駒の平坦な対向壁間にカッター刃を挟持固定するようになしたことを特徴とする超音波切断装置におけるホーンへのカッター刃の固定方法にある。   Therefore, the gist of the present invention is that a triangular notch that is deepest in the center of the horn is provided on the tip surface of the horn, and each flat inclined surface of the triangular notch is provided with each inclined surface. Attach a pair of clamping pieces that slide in the contact and separation direction along the inclined surface by the screwing of the screw threaded parallel to the axis of the horn on the surface, and insert a cutter blade between the flat opposing walls of the pair of clamping pieces The present invention resides in a method for fixing a cutter blade to a horn in an ultrasonic cutting apparatus characterized by being clamped and fixed.

また、上記構成を更に具体化した、ホーンの先端面に、ホーンの中心部において最も深くなる三角形状の切り込みを設け、該三角形状の切り込みの各平坦な傾斜面の夫々に、該傾斜面の夫々と同一角度の傾斜面を設けて該傾斜面に沿って摺動自在となすと共に、双方の対向壁をホーンの軸と平行な平坦面となした一対の挟持駒を、それらの中心部に穿設したホーンの軸方向に沿い且つ前記三角形状の切り込みの傾斜面の浅深方向に長いネジ挿通孔に挿通した、ホーンの前記三角形状の切り込みの各傾斜面にホーンの軸と平行に螺装した六角孔付き頭部のネジをもって保持し、前記ネジを螺進させ、その頭部で前記一対の挟持駒の夫々を前記三角形状の切り込みの傾斜面に押し付けることによって双方の対向間隙を狭め、もってこれら一対の挟持駒間にカッター刃を挟持固定するようになしたことを特徴とする超音波切断装置におけるホーンへのカッター刃の固定方法も、その要旨とするものである。   Further, the above-described configuration is further embodied, and a triangular incision that is deepest in the center of the horn is provided on the front end surface of the horn, and each of the flat inclined surfaces of the triangular incision is provided with each of the inclined surfaces. A pair of sandwiching pieces, each of which has an inclined surface of the same angle and is slidable along the inclined surface, and whose opposing walls are flat surfaces parallel to the horn axis, Along the axial direction of the drilled horn and through a screw insertion hole that is long in the shallow depth direction of the inclined surface of the triangular notch, each triangular inclined surface of the horn is threaded parallel to the horn axis. Held with a hexagonal hole head screw mounted, the screw is screwed, and the opposing gap is narrowed by pressing each of the pair of holding pieces against the inclined surface of the triangular notch with the head, With these pairs Fixing method of the cutter blade to the horn in the ultrasonic cutting device being characterized in that none so as to sandwich the fixed cutter blade between frames is also one in which the gist thereof.

また、上記構成において、ホーンの先端面における前記三角形状の切り込みのいずれか一方側の外端近傍位置に、前記一対の挟持駒のカッター刃の接触壁と反対側の壁面に接触する、前記一対の挟持駒の対向壁と平行する突起を設けるようになしてもよい。   Further, in the above-described configuration, the pair of the pair of sandwiching pieces that are in contact with the wall on the opposite side to the contact wall of the cutter blade at a position near the outer end on either side of the triangular notch on the tip surface of the horn. You may make it provide the protrusion parallel to the opposing wall of a clamping piece.

また、上記構成において、一対の挟持駒を、その横断面形状を方形状とし、該一対の挟持駒とは別体の、一対の挟持枠からなり、双方の合わせ目の中央部に該一対の挟持駒と略同形同大の切り込みを設けると共に、適宜の手段をもって接離自在とした位置決め用補助具を用い、該位置決め用補助具を、該一対の挟持駒の対向間隙を狭めるときに該一対の挟持駒に被せてカッター刃の位置決めを行うようになしてもよい。   Further, in the above configuration, the pair of holding pieces has a rectangular cross-sectional shape, and is formed of a pair of holding frames that are separate from the pair of holding pieces, and the pair of holding pieces are arranged at the center of both the joints. A positioning aid that is provided with a notch of approximately the same shape and size as the sandwiching piece and that can be freely attached and separated by appropriate means is used to narrow the opposing gap between the pair of sandwiching pieces. The cutter blade may be positioned over the holding piece.

本発明は上記の如き構成であるから、ホーンの先端面に設けた三角形状の切り込みの各平坦な傾斜面の夫々に摺動自在に取付けた一対の挟持駒を、各傾斜面にホーンの軸と平行に螺装したネジを螺進させることによってその頭部で押圧して相互間の距離を縮め、それらの平坦な対向壁間にカッター刃を挟持固定するようになしたものであるから、挟持した状態においては一対の挟持駒はいずれもその対向壁がカッター刃と平行し、もって該カッター刃に対して面で接触するものである。したがって、接触面積が大きいことから従来方法に比してはるかに把持力が増大することになるものである。   Since the present invention is configured as described above, a pair of sandwiching pieces slidably attached to each of the flat inclined surfaces of the triangular notch provided on the tip surface of the horn are provided on each inclined surface. Because the screw screwed in parallel with the head is pressed at its head to reduce the distance between them, and the cutter blade is sandwiched and fixed between those flat opposing walls, In the clamped state, each of the pair of clamping pieces has an opposing wall parallel to the cutter blade, and thus makes contact with the cutter blade on the surface. Therefore, since the contact area is large, the gripping force is much increased as compared with the conventional method.

また、一対の挟持駒は、ホーンの三角形状の切り込みの各平坦な傾斜面に沿って接離方向に摺動し、そして最終的に平坦な両対向壁は自然に平行した状態になるものであるから、これら一対の挟持駒に把持された状態においては、カッター刃は必然的にホーンの円周方向に対して一定の位置になるものである。したがって、従来方法におけるが如く、カッター刃の交換の度毎にホーンに対する位置がずれ、一々再セットし直す手間と時間を不要とすることができるものである。加えて、一対の挟持駒の対向壁が摩耗した場合においては、これを研磨等によって修正することにより、再使用することが可能となるものである。   The pair of sandwiching pieces slide in the approaching / separating direction along the flat inclined surfaces of the triangular cuts of the horn, and finally the flat opposing walls are naturally parallel. Therefore, in a state of being gripped by the pair of sandwiching pieces, the cutter blade inevitably becomes a fixed position with respect to the circumferential direction of the horn. Therefore, as in the conventional method, the position relative to the horn is shifted every time the cutter blade is replaced, and the labor and time for resetting one by one can be eliminated. In addition, when the opposing walls of the pair of sandwiching pieces are worn, they can be reused by correcting them by polishing or the like.

また、ホーンの先端面における前記三角形状の切り込みのいずれか一方側の外端近傍位置に、前記一対の挟持駒のカッター刃の接触壁と反対側の壁面に接触する、前記一対の挟持駒の対向壁と平行する突起を設けるようになした場合には、一対の挟持駒の対向壁と平行する突起が、該一対の挟持駒のいずれか一方の位置決めストッパーとして作用し、もって一対の挟持駒によるカッター刃の挟持状態の稼働中におけるずれを防いで、確固として保持することができるものである。また、カッター刃のホーンの円周方向に対する位置の確保もより一層確実に行うことができるようになるものである。   Further, the opposing walls of the pair of sandwiching pieces that come into contact with the wall surface on the opposite side of the contact wall of the cutter blade of the pair of sandwiching pieces at a position near the outer end on either side of the triangular notch on the tip surface of the horn. When the projection parallel to the pair of sandwiching pieces is provided, the projection parallel to the opposing wall of the pair of sandwiching pieces acts as a positioning stopper for one of the pair of sandwiching pieces. It is possible to prevent misalignment during operation in the sandwiched state and hold it firmly. In addition, the position of the cutter blade in the circumferential direction of the horn can be ensured more reliably.

また、一対の挟持駒をその横断面形状を方形状とし、該一対の挟持駒とは別体の、一対の挟持枠からなり、双方の合わせ目の中央部に該一対の挟持駒と略同形同大の切り込みを設けると共に、適宜の手段をもって接離自在とした位置決め用補助具を用い、該位置決め用補助具を、該一対の挟持駒の対向間隙を狭めるときに該一対の挟持駒に被せてカッター刃の位置決めを行うようになした場合には、より迅速に且つ確実にカッター刃の把持力の増大とカッター刃の位置決めを行うことができるものである。即ち、斯かる場合には、両方の挟持駒は一対の挟持枠によってその切り込み内においてずれるようになるから、両方の挟持駒は向きを規制されて、その対向壁を平行に維持した状態で接近することになり、もって、カッター刃の固定作業時において迅速且つ確実に、両方の挟持駒の各対向壁を、カッター刃に対してその全面を均一に密接させるようにすることができるものである。また、カッター刃を、確実に三角形状の切り込みの最深部、即ちホーンの中心部に位置させることができると共に、カッター刃の向きを常に一定にすることができるものである。   Further, the pair of holding pieces has a square cross-sectional shape and is composed of a pair of holding frames that are separate from the pair of holding pieces, and is substantially the same as the pair of holding pieces at the center of both joints. A positioning aid that is provided with a notch of the same size and that can be contacted and separated by appropriate means is used to cover the pair of sandwiching pieces when the opposing gap between the pair of sandwiching pieces is narrowed. Thus, when the cutter blade is positioned, the gripping force of the cutter blade can be increased and the cutter blade can be positioned more quickly and reliably. That is, in such a case, since both the holding pieces are displaced in the notch by the pair of holding frames, both the holding pieces are restricted in direction and approached with their opposing walls maintained in parallel. As a result, the opposing walls of both sandwiching pieces can be brought into close contact with the cutter blade evenly and reliably during the fixing operation of the cutter blade. Further, the cutter blade can be surely positioned at the deepest portion of the triangular cut, that is, the center portion of the horn, and the direction of the cutter blade can always be made constant.
