Description

本発明は、超音波振動を利用して薄く長い生地やシートなどを連続的に溶着または溶断する超音波連続溶着溶断装置に関する。   The present invention relates to an ultrasonic continuous welding fusing device that continuously welds or cuts a thin and long fabric or sheet using ultrasonic vibration.

一般的に超音波溶着装置は、振動子と該振動子に連結されたホーンとを有する超音波ユニットを備え、該超音波ユニットがアクチュエータによって昇降自在に支持され、ホーンが被加工物を載置する受け冶具の真上に対向配置される。また、発振器で増幅された所定周波数の電気信号が振動子へと伝えられ、そこで機械振動エネルギーに変換され、その振動エネルギーが振動子からホーンに伝達され、ホーンを振動させる。   In general, an ultrasonic welding apparatus includes an ultrasonic unit having a vibrator and a horn coupled to the vibrator, the ultrasonic unit is supported by an actuator so as to be movable up and down, and the horn places a workpiece. It is arranged to face the receiving jig just above. In addition, an electric signal having a predetermined frequency amplified by the oscillator is transmitted to the vibrator, where it is converted into mechanical vibration energy, and the vibration energy is transmitted from the vibrator to the horn to vibrate the horn.

特許文献１には、アクチュエータに空気圧シリンダを用いた超音波溶着装置が示されている。該超音波溶着装置によって受け冶具に載置した例えば２つの熱可塑性樹脂パーツの溶着を行う場合、空気圧シリンダを駆動制御して超音波ユニットを下降させ、ホーンを熱可塑性樹脂パーツに押し付け、熱可塑性樹脂パーツに所定の加圧力を印加しながら、ホーンから熱可塑性樹脂パーツに超音波振動を付与する。これにより、２つの熱可塑性樹脂パーツの接合面では強力な摩擦熱が発生し、樹脂の溶融温度にまで瞬時に上昇し、溶着される。   Patent Document 1 discloses an ultrasonic welding apparatus using a pneumatic cylinder as an actuator. When, for example, two thermoplastic resin parts placed on a receiving jig are welded by the ultrasonic welding apparatus, the pneumatic unit is driven and controlled, the ultrasonic unit is lowered, and the horn is pressed against the thermoplastic resin parts to make thermoplasticity. While applying a predetermined pressure to the resin part, ultrasonic vibration is applied from the horn to the thermoplastic resin part. As a result, strong frictional heat is generated at the joining surface of the two thermoplastic resin parts, and the temperature rises instantaneously to the melting temperature of the resin and is welded.

また、超音波溶着によって薄く長い生地やシートなどを連続的に溶着または溶断する超音波連続溶着溶断装置では、例えば特許文献２〜５に示されているように、上述した超音波溶着装置の受け冶具に回転ローラを用い、相対するホーンと回転ローラ間に薄く長い生地やシートなどの被加工物を所定の送り速度で連続的に送り、ホーンが空気圧シリンダから付与された押え圧力によって被加工物に押し付きながら、超音波振動を該被加工物に連続的に付与することにより、該被加工物を超音波振動と加圧力によって連続的に溶着する。なお、一般的な超音波連続溶着溶断装置の場合、発振周波数１０ｋＨｚ〜５０ｋＨｚ、振幅１０μｍ〜１００μｍ、超音波出力数１０Ｗ〜数ｋＷ、印加圧力１０Ｎ〜１０００Ｎ、送り速度１ｍ／ｍｉｎ〜５０ｍ／ｍｉｎである。

A rotating roller is used as a jig, and workpieces such as thin and long fabrics and sheets are continuously fed at a specified feed speed between the opposing horn and the rotating roller, and the horn is pressed by the pressing pressure applied from the pneumatic cylinder. By continuously applying ultrasonic vibration to the workpiece while pressing against the workpiece, the workpiece is continuously welded by ultrasonic vibration and pressure. In the case of a general ultrasonic continuous welding fusing device, the oscillation frequency is 10 kHz to 50 kHz, the amplitude is 10 μm to 100 μm, the ultrasonic output is 10 W to several kW, the applied pressure is 10 N to 1000 N, and the feed rate is 1 m / min to 50 m / min. is there.

図５は上述した従来の超音波連続溶着溶断装置の溶着溶断部を示す部分拡大図であり、図中の１がホーン、２が回転ローラ、３が薄く長い生地やシートなどの被加工物、つまりワーク、４はワーク３に発生したシワである。また、図６は上述した従来の超音波連続溶着溶断装置の動作チャートである。図５に示したシワ４は、ワーク３を加熱することでそのほとんどの素材に生じる伸びと、ホーン１がワーク３を押え付けていることで生じるワーク３両面の摩擦抵抗差によって発生し、特にワーク３が加熱されやすい素材または伸縮性が高い素材の場合には多く発生し、超音波連続溶着または溶断の仕上がり風合いを低下させることが確認されている。しかも図６に示すように、ワーク３に対する印加圧力Ｐを一定に保った状態で超音波連続溶着または溶断を行うために、その超音波連続溶着または溶断開始からの経過時間に比例してシワ４の発生が積算され、ワーク３の長さが長くなるに連れて仕上がり風合いの低下の度合いが大きくなる。ワーク３に対する印加圧力Ｐを低下させることで、そのシワ４を抑制することは可能であるが、その場合、ワーク３に付与される振動エネルギーも低下するために、適正な溶着強度または溶断が得られない。このように従来の超音波連続溶着溶断装置では、シワが発生し仕上がり風合いが低下することを抑制できないという課題があった。   FIG. 5 is a partial enlarged view showing a welding fusing part of the above-described conventional ultrasonic continuous fusing and fusing device, in which 1 is a horn, 2 is a rotating roller, 3 is a work piece such as a thin and long fabric or sheet, That is, the workpiece 4 is a wrinkle generated in the workpiece 3. FIG. 6 is an operation chart of the conventional ultrasonic continuous welding fusing apparatus described above. The wrinkles 4 shown in FIG. 5 are generated by the elongation generated in most of the material by heating the workpiece 3 and the frictional resistance difference between both surfaces of the workpiece 3 caused by the horn 1 pressing the workpiece 3. It has been confirmed that the workpiece 3 is frequently generated when it is easily heated or highly stretchable, and the finished texture of continuous welding or fusing is reduced. Moreover, as shown in FIG. 6, in order to perform continuous ultrasonic welding or fusing while keeping the applied pressure P to the workpiece 3 constant, wrinkles 4 are proportional to the elapsed time from the start of the ultrasonic continuous welding or fusing. As the length of the work 3 becomes longer, the degree of decrease in the finished texture increases. It is possible to suppress the wrinkle 4 by reducing the applied pressure P to the work 3, but in this case, the vibration energy imparted to the work 3 is also reduced, so that an appropriate welding strength or fusing is obtained. I can't. As described above, the conventional ultrasonic continuous welding fusing device has a problem that wrinkles are generated and it is not possible to prevent the finished texture from being lowered.

上記課題を解決するための本発明の超音波連続溶着溶断装置は、相対するホーンと回転ローラ間に薄く長いワークが連続的に送られ、前記ホーンが空気圧シリンダから付与された押え圧力によってワークに押し付きながら超音波振動を該ワークに連続的に付与し、該ワークを超音波振動と加圧力によって連続的に溶着または溶断する超音波連続溶着溶断装置であって、溶着または溶断時にホーン押え用電磁弁を介して前記空気圧シリンダに印加した空気圧力を一定周期で開放するホーン押え圧力開放用電磁弁を設けたことを特徴とする。   In order to solve the above problems, the ultrasonic continuous welding fusing device of the present invention is such that a thin and long workpiece is continuously sent between an opposing horn and a rotating roller, and the horn is applied to the workpiece by a presser pressure applied from a pneumatic cylinder. An ultrasonic continuous welding fusing device that continuously applies ultrasonic vibration to the workpiece while pressing, and continuously welds or cuts the workpiece by ultrasonic vibration and pressure, for holding the horn during welding or fusing A horn presser pressure release solenoid valve is provided that releases the air pressure applied to the pneumatic cylinder via a solenoid valve at a constant period.

本発明の超音波連続溶着溶断装置によれば、溶着または溶断時にホーン押え圧力開放用電磁弁の駆動信号を一定周期でＯＮ／ＯＦＦさせることで、ホーン押え用電磁弁を介して前記空気圧シリンダに印加した空気圧力を一定周期で加圧／開放を繰り返す。これにより、ワークに印加される加圧力Ｐが一定周期で変化する（Ｐ→Ｐ２→Ｐ→Ｐ２→・・・、但し、Ｐ＝Ｐ１＋Ｐ２、Ｐ１：空気圧シリンダによりワークに印加される圧力、Ｐ２：空気圧シリンダにより支えられるホーンを含む超音波ユニットの荷重）。このようにワークに印加される加圧力Ｐが一定周期で変化するため、シワの発生が積算されず、空気圧シリンダに印加する空気圧力Ｐ１が開放される度に、発生したシワが減少する。つまりシワが発生／減少を繰り返すことで、シワの発生が積算されず抑制することができ、良好な仕上がり風合いを得ることができる。また、ワークに対する印加圧力を一定周期で変化させると、適正溶着／未溶着または適正溶断／未溶断が繰り返されるように感じるが、加圧時間と開放時間を適正な時間に設定することで、未溶着部分または未溶断部分を限りなくゼロにすることができ、実用上問題のない適正な溶着強度または溶断を得ることができる。   According to the ultrasonic continuous welding fusing device of the present invention, the driving signal of the solenoid valve for releasing the horn presser pressure is turned ON / OFF at a constant cycle during welding or fusing, so that the pneumatic cylinder is connected to the pneumatic cylinder via the horn presser solenoid valve. Repeated pressurization / release of the applied air pressure at regular intervals. As a result, the pressure P applied to the workpiece changes at a constant cycle (P → P2 → P → P2 →..., Where P = P1 + P2, P1: pressure applied to the workpiece by the pneumatic cylinder, P2: The load of the ultrasonic unit including the horn supported by the pneumatic cylinder). Since the applied pressure P applied to the workpiece changes in a constant cycle as described above, the generation of wrinkles is not integrated, and the generated wrinkles decrease every time the air pressure P1 applied to the pneumatic cylinder is released. That is, by repeating the generation / reduction of wrinkles, the generation of wrinkles can be suppressed without being integrated, and a good finished texture can be obtained. In addition, when the applied pressure to the workpiece is changed at a certain period, it seems that proper welding / non-welding or proper fusing / uncutting is repeated, but by setting the pressurization time and release time to appropriate times, The welded portion or the unfused portion can be reduced to zero as much as possible, and an appropriate welding strength or fusing without any practical problem can be obtained.

本発明によれば、超音波連続溶着または溶断時に、ワークにシワが発生し仕上がり風合いが低下することを適正に抑制することができるという顕著な効果を奏する。   ADVANTAGE OF THE INVENTION According to this invention, there exists a remarkable effect that it can suppress appropriately that a wrinkle generate | occur | produces on a workpiece | work and a finished texture falls at the time of continuous ultrasonic welding or cutting.

Therefore, the vibration energy is converted into mechanical vibration energy, and the vibration energy is transmitted from the vibrator 21 to the horn 22 to vibrate the horn 22.

スライド機構４０は、支持フレーム３０に垂直に取り付けるガイド棒４１と、ガイド棒４１に摺動自在に取り付ける上下一対の摺動子４２と、上下の摺動子４２を一体に連結する連結板４３と、連結板４３から一体に延出された超音波ユニット取り付けフレーム４４とを有して構成され、超音波ユニット取り付けフレーム４４に取り付けた前記超音波ユニット２０をガイド棒４１に沿って上下にスライド移動自在に支持フレーム３０に取り付ける。   The slide mechanism 40 includes a guide bar 41 that is vertically attached to the support frame 30, a pair of upper and lower sliders 42 that are slidably attached to the guide bar 41, and a connecting plate 43 that integrally connects the upper and lower sliders 42. And the ultrasonic unit mounting frame 44 integrally extended from the connecting plate 43, and the ultrasonic unit 20 mounted on the ultrasonic unit mounting frame 44 is slid up and down along the guide rod 41. Attached to the support frame 30 freely.

空気圧シリンダ５０は、支持フレーム３０の上部に垂直に取り付ける円筒状の本体部５１と、該本体部５１の下面から下向きに突出させて、突出端部を上側の摺動子４２に連結するロッド５２とを有して構成され、空気圧シリンダ５０の伸縮運動によって前記超音波ユニット２０を昇降させる。   The pneumatic cylinder 50 includes a cylindrical main body 51 that is vertically attached to the upper portion of the support frame 30, and a rod 52 that protrudes downward from the lower surface of the main body 51 and connects the protruding end to the upper slider 42. The ultrasonic unit 20 is moved up and down by the expansion and contraction of the pneumatic cylinder 50.

回転ローラ６０は、生地やシートなどの薄く長いワーク７０の送り方向と直交する水平な駆動軸６１を介して前記超音波ユニット２０の真下に軸支される。   The rotating roller 60 is pivotally supported directly below the ultrasonic unit 20 via a horizontal drive shaft 61 orthogonal to the feeding direction of a thin and long workpiece 70 such as a cloth or a sheet.

そして、図２にも示すように、上部に前記ホーン２２を有し、下部に前記回転ローラ６０を有し、これら相対するホーン２２と回転ローラ６０間に前記ワーク７０が連続的に送られ、前記ホーン２２が空気圧シリンダ５０から付与された押え圧力によってワーク７０に押し付きながら超音波振動を該ワーク７０に連続的に付与し、該ワーク７０を超音波振動と加圧力によって連続的に溶着または溶断する溶着溶断部を形成している。   And as shown also in FIG. 2, it has the said horn 22 in the upper part, and has the said rotation roller 60 in the lower part, The said workpiece | work 70 is sent continuously between these horn 22 and the rotation roller 60, Ultrasonic vibration is continuously applied to the work 70 while the horn 22 is pressed against the work 70 by the pressing force applied from the pneumatic cylinder 50, and the work 70 is continuously welded by the ultrasonic vibration and the applied pressure. A welded and melted portion to be melted is formed.

また、図３に示すように、ポンプ（コンプレッサー）などの空気圧力源５３からフィルタ５４ａおよび減圧弁５４ｂを有する空気圧調整ユニット５４を通して供給される圧縮空気を、空気圧シリンダ５０の本体部５１ヘッド側および本体部５１ロッド側に択一的に送り込む２位置５ポートの電磁弁であるホーン押え用電磁弁５５を設けており、ホーン押え用電磁弁５５のソレノイド５５ａがＯＦＦになった状態（図３に示す状態）で、下降側の速度制御弁（チェック弁付き絞り弁）５６を通して空気圧シリンダ５０の本体部５１ロッド側に圧縮空気を送り込み、空気圧シリンダ５０のロッド５２を上向きに後退させて、空気圧シリンダ５０を縮小させ、超音波ユニット２０を上昇させる。このとき空気圧シリンダ５０の本体部５１ヘッド側から押し出される空気を上昇側の速度制御弁（チェック弁付き絞り弁）５７を通して大気に放出させ、メータアウトにて超音波ユニット２０の上昇速度を一定に保つ。このように超音波ユニット２０を上昇させることで、ホーン２２をワーク７０に対し離反保持するように構成している。一方、ホーン押え用電磁弁５３のソレノイド５３ａがＯＮになった状態（図３に示す状態）で、上昇側の速度制御弁５７を通して空気圧シリンダ５０の本体部５１ヘッド側に圧縮空気を送り込み、空気圧シリンダ５０のロッド５２を下向きに前進させて、空気圧シリンダ５０を伸長させ、超音波ユニット２０を下降させる。このとき空気圧シリンダ５０の本体部５１ロッド側から押し出される空気を下降側の速度制御弁５６を通して大気に放出させ、メータアウトにて超音波ユニット２０の下降速度を一定に保つ。このように超音波ユニット２０を下降させることで、ホーン２２をワーク７０に押し付け、ワーク７０に対し所定の加圧力Ｐを印加するように構成している。このときのワーク７０に対する印加圧力Ｐは、図４に示すように、空気圧シリンダ５０の本体部５１ヘッド側に印加された空気圧力、つまり空気圧シリンダ５０によりホーン２２に加えられる押え圧力Ｐ１と、超音波ユニット２０の荷重Ｐ２とを合算したものである（Ｐ＝Ｐ１＋Ｐ２）。   Further, as shown in FIG. 3, compressed air supplied from an air pressure source 53 such as a pump (compressor) through a pneumatic pressure adjusting unit 54 having a filter 54a and a pressure reducing valve 54b is supplied to the main body 51 head side of the pneumatic cylinder 50 and A horn-pressing solenoid valve 55, which is a 2-position 5-port solenoid valve that is alternatively sent to the rod side of the main body 51, is provided, and the solenoid 55a of the horn-pressing solenoid valve 55 is turned off (see FIG. 3). In the state shown), compressed air is fed to the rod 51 side of the main body 51 of the pneumatic cylinder 50 through the speed control valve (throttle valve with check valve) 56, and the rod 52 of the pneumatic cylinder 50 is retracted upward, so that the pneumatic cylinder 50 is reduced and the ultrasonic unit 20 is raised. At this time, the air pushed out from the head side of the main body 51 of the pneumatic cylinder 50 is released to the atmosphere through the ascending speed control valve (throttle valve with check valve) 57, and the ascending speed of the ultrasonic unit 20 is made constant by meter-out. keep. By raising the ultrasonic unit 20 in this way, the horn 22 is configured to be held away from the work 70. On the other hand, in a state where the solenoid 53a of the horn presser solenoid valve 53 is ON (the state shown in FIG. 3), compressed air is sent to the main body 51 head side of the pneumatic cylinder 50 through the speed control valve 57 on the rising side. The rod 52 of the cylinder 50 is advanced downward, the pneumatic cylinder 50 is extended, and the ultrasonic unit 20 is lowered. At this time, the air pushed out from the rod 51 side of the main body 51 of the pneumatic cylinder 50 is released to the atmosphere through the speed control valve 56 on the lower side, and the lowering speed of the ultrasonic unit 20 is kept constant by meter-out. In this way, the ultrasonic unit 20 is moved down so that the horn 22 is pressed against the work 70 and a predetermined pressure P is applied to the work 70. As shown in FIG. 4, the applied pressure P to the work 70 at this time is the air pressure applied to the main body 51 head side of the pneumatic cylinder 50, that is, the presser pressure P <b> 1 applied to the horn 22 by the pneumatic cylinder 50, This is the sum of the load P2 of the sound wave unit 20 (P = P1 + P2).

ここで、ホーン押え用電磁弁５５と上昇側の速度制御弁５７との間に、空気圧シリンダ５０によりホーン２２に加える押え圧力Ｐ１を設定するための圧力制御弁（減圧弁またはチェック弁付き減圧弁）５８を設け、空気圧シリンダ５０を超音波ユニット２０の上昇時に高圧で用い、下降時に上昇時より低圧で用いる。つまり圧力制御弁５８によって余剰圧力を逃がし（大気開放）、予め設定された空気圧力（押え圧力Ｐ１）を空気圧シリンダ５０の本体部５１ヘッド側に印加し、空気圧シリンダ５０によりホーン２２に押え圧力Ｐ１を加えるように構成している。なお、この押え圧力Ｐ１の調整は圧力制御弁５８にバネ圧を調整できる減圧弁またはチェック弁付き減圧弁を用いることで容易に行うことができる。   Here, a pressure control valve (a pressure reducing valve or a pressure reducing valve with a check valve) for setting a pressure pressure P1 applied to the horn 22 by the pneumatic cylinder 50 between the horn pressing electromagnetic valve 55 and the speed control valve 57 on the ascending side. 58) and the pneumatic cylinder 50 is used at a high pressure when the ultrasonic unit 20 is raised, and is used at a lower pressure than when it is raised. That is, surplus pressure is released by the pressure control valve 58 (atmospheric release), and a preset air pressure (pressing pressure P1) is applied to the head portion 51 side of the pneumatic cylinder 50, and the pressing pressure P1 is applied to the horn 22 by the pneumatic cylinder 50. It is configured to add. The presser pressure P1 can be easily adjusted by using a pressure reducing valve capable of adjusting the spring pressure or a pressure reducing valve with a check valve for the pressure control valve 58.

また、前記圧力制御弁と上昇側の速度制御弁５７との間に、ホーン押え用電磁弁５５および圧力制御弁５８を通じて空気圧シリンダ５０の本体部５１ヘッド側に印加する所定の空気圧力（押え圧力Ｐ１）を一定周期で開放するための２位置３ポートの電磁弁であるホーン押え圧力開放用電磁弁５９を設けており、ホーン押え圧力開放用電磁弁５９の駆動信号を一定周期でＯＮ／ＯＦＦさせることで、ホーン押え圧力開放用電磁弁５９のソレノイド５９ａがＯＦＦになった状態（図３に示す状態）で、空気圧シリンダ５０の本体部５１ヘッド側に所定の空気圧力を印加し、空気圧シリンダ５０によりホーン２２に押え圧力Ｐ１を加える一方、ホーン押え圧力開放用電磁弁５９のソレノイド５９ａがＯＮになった状態で、空気圧シリンダ５０の本体部５１ヘッド側に印加する空気圧力（押え圧力Ｐ１）を遮断し、同時に空気圧シリンダ５０の本体部５１ヘッド側を大気に開放して、空気圧シリンダ５０によりホーン２２に加える押え圧力Ｐ１をなくす。このように空気圧シリンダ５０の本体部５１ヘッド側に印加した空気圧力（押え圧力Ｐ１）を一定周期で加圧／開放を繰り返すことにより、図４に示すように、ワーク７０に印加する加圧力Ｐを一定周期で変化（Ｐ→Ｐ２→Ｐ→Ｐ２→・・・）させるように構成している。この際、加圧時間（ホーン押え圧力開放用電磁弁５９の駆動信号ＯＮ時間）ｔ２と開放時間（ホーン押え圧力開放用電磁弁５９の駆動信号ＯＦＦ時間）ｔ１を適正な時間（例えば加圧時間ｔ１を開放時間ｔ２よりも十分に長くする、つまりデューティを大きくする）に設定することで、未溶着部分または未溶断部分を限りなくゼロにすることができ、実用上問題のない適正な溶着強度または溶断を得ることができる。   Further, a predetermined air pressure (pressing pressure) applied to the main body 51 head side of the pneumatic cylinder 50 through the horn pressing electromagnetic valve 55 and the pressure control valve 58 between the pressure control valve and the speed control valve 57 on the ascending side. A horn presser pressure release solenoid valve 59, which is a 2-position 3-port solenoid valve for releasing P1) at a constant cycle, is provided, and the drive signal for the horn presser pressure release solenoid valve 59 is turned ON / OFF at a constant cycle. Thus, in the state where the solenoid 59a of the solenoid valve 59 for releasing the horn presser pressure is OFF (the state shown in FIG. 3), a predetermined air pressure is applied to the head side of the main body 51 of the pneumatic cylinder 50, and the pneumatic cylinder 50, the presser pressure P1 is applied to the horn 22 while the solenoid 59a of the horn presser pressure release solenoid valve 59 is turned on. Part 51 is shut off air pressure to be applied to the head side (pressing pressure P1), at the same time the body portion 51 the head side of the pneumatic cylinder 50 open to the atmosphere, eliminating the presser pressure P1 applied to the horn 22 by pneumatic cylinder 50. In this way, by repeatedly pressurizing / releasing the air pressure (pressing pressure P1) applied to the main body 51 head side of the pneumatic cylinder 50 at a constant cycle, the applied pressure P applied to the workpiece 70 as shown in FIG. Is changed at a constant cycle (P → P2 → P → P2 →...). At this time, pressurization time (drive signal ON time of the horn presser pressure release solenoid valve 59) t2 and release time (drive signal OFF time of the horn presser pressure release solenoid valve 59) t1 are appropriate times (for example, pressurization time). By setting t1 to be sufficiently longer than the opening time t2, that is, to increase the duty), the unwelded portion or the unfused portion can be made zero as much as possible, and an appropriate welding strength with no practical problem Or fusing can be obtained.

次に、上記のように構成された本実施形態の超音波連続溶着溶断装置１０によりワーク７０（具体的には、重ね合わせた２枚の生地同士またはシート同士）を連続的に溶着またはワーク７０（具体的には、１枚の生地またはシート）を連続的に溶断する場合の動作を図４を参照しながら説明する。   Next, the workpiece 70 (specifically, two overlapped fabrics or sheets) are continuously welded or the workpiece 70 by the ultrasonic continuous welding fusing device 10 of the present embodiment configured as described above. The operation in the case of fusing (specifically, one piece of fabric or sheet) will be described with reference to FIG.

まず、空気圧シリンダ５０により超音波ユニット２０を上昇位置に支持した状態で、相対するホーン２２と回転ローラ６０との間に溶着または溶断するワーク７０を通した後、空気圧シリンダ５０により超音波ユニット２０を下降させ、ホーン２２をワーク７０に押し付け、ワーク７０に対し所定の加圧力Ｐを印加すると共に、発振器を発振状態にして振動子２１を振動させ、その超音波振動をホーン２２を通してワーク７０に伝達する。この発振状態（図２の状態）で回転ローラ６０を回転駆動させ、ホーン２２と回転ローラ６０との間にワーク７０を連続的に送り込み、通常通り溶着または溶断作業を開始する。   First, in a state where the ultrasonic unit 20 is supported at the raised position by the pneumatic cylinder 50, the workpiece 70 to be welded or blown is passed between the opposing horn 22 and the rotating roller 60, and then the ultrasonic unit 20 is used by the pneumatic cylinder 50. , The horn 22 is pressed against the work 70, a predetermined pressure P is applied to the work 70, the oscillator 21 is oscillated to vibrate the vibrator 21, and the ultrasonic vibration is applied to the work 70 through the horn 22. introduce. In this oscillation state (the state shown in FIG. 2), the rotary roller 60 is rotationally driven, and the workpiece 70 is continuously fed between the horn 22 and the rotary roller 60, and welding or fusing work is started as usual.

そして、溶着または溶断作業開始に伴って、ホーン押え圧力開放用電磁弁５９の駆動信号を一定周期でＯＮ／ＯＦＦさせ、空気圧シリンダ５０に印加した空気圧力Ｐ１を一定周期で開放し、ワーク７０に印加する加圧力Ｐを一定周期で変化（Ｐ→Ｐ２→Ｐ→Ｐ２→・・・）させながら、ホーン２２と回転ローラ６０との間に連続的に送り込まれるワーク７０を、超音波振動と一定周期で変化させる加圧力（Ｐ→Ｐ２→Ｐ→Ｐ２→・・・）によって連続的に溶着または溶断する。   Then, with the start of welding or fusing operation, the drive signal of the horn presser pressure release solenoid valve 59 is turned on / off at a constant cycle, the air pressure P1 applied to the pneumatic cylinder 50 is released at a constant cycle, and the workpiece 70 is released. While changing the applied pressure P at a constant cycle (P → P2 → P → P2 →...), The workpiece 70 continuously fed between the horn 22 and the rotating roller 60 is made constant with ultrasonic vibration. The welding is continuously welded or cut by the applied pressure (P → P2 → P → P2 →.

このようにワーク７０に印加する加圧力Ｐを一定周期で変化（Ｐ→Ｐ２→Ｐ→Ｐ２→・・・）させることにより、従来のようにシワ４の発生が積算されず、空気圧シリンダ５０に印加する空気圧力Ｐ１が開放される度に、発生したシワ４が減少する。つまりシワ４が発生／減少を繰り返すことで、シワ４の発生が積算されず抑制することができ、良好な仕上がり風合いを得ることができる。また、加圧時間ｔ２と開放時間ｔ１を適正な時間に設定することで、未溶着部分または未溶断部分を限りなくゼロにすることができ、実用上問題のない適正な溶着強度または溶断を得ることができる。   In this way, by changing the pressure P applied to the work 70 at a constant cycle (P → P2 → P → P2 →...), The generation of wrinkles 4 is not integrated as in the conventional case, and the pneumatic cylinder 50 is not accumulated. Every time the applied air pressure P1 is released, the generated wrinkles 4 decrease. That is, by repeating the generation / reduction of wrinkles 4, the generation of wrinkles 4 can be suppressed without being integrated, and a good finished texture can be obtained. Further, by setting the pressurization time t2 and the release time t1 to appropriate times, the unwelded portion or the unfused portion can be reduced to zero as much as possible, and an appropriate welding strength or fusing without any practical problems can be obtained. be able to.

したがって、本実施形態の超音波連続溶着溶断装置１０によれば、適正な溶着強度または溶断を得ながら、ワーク７０にシワ４が発生し仕上がり風合いが低下することを適正に抑制することができる。また、加圧時間ｔ２と開放時間ｔ１を調整することで、他の条件（発振周波数、振幅、超音波出力、印加圧力、送り速度）を変化させることなく、仕上がり風合いを変化させることもできる。   Therefore, according to the ultrasonic continuous welding fusing device 10 of the present embodiment, it is possible to appropriately suppress the occurrence of wrinkles 4 on the workpiece 70 and a reduction in the finished texture while obtaining appropriate welding strength or fusing. Further, by adjusting the pressurization time t2 and the release time t1, it is possible to change the finished texture without changing other conditions (oscillation frequency, amplitude, ultrasonic output, applied pressure, feed rate).
