Description

【０００１】
【発明の技術分野】
本発明は、包装用の多数の袋を形成するために、帯状フイルムを長手方向に沿ってチューブに丸めると共に、該チューブフイルムの重なり両側縁を超音波振動によって溶着する装置に関する。
【０００２】
【従来技術の課題】
筒形に丸めたフイルム両側縁の重なり部を超音波振動によつて生ずる熱により溶着する従来装置は、図７に示すごとく、上下に振動するハンマー１０と、機台１１に固定したハンマー台１２との間に２枚の重ね合わせたフイルム１３を矢印１４の方向に移動させ、ハンマーから加わる振動熱によってフイルム１３を連続的に溶着するものであるが、前記フイルム１３の厚みには微妙な差があるから溶着強度が各領域で異なり、例えば真空包装した場合に空気漏れが起こることがある。
【０００３】
【目的】
そこで本発明は、フイルムに対する振動衝撃力を平均化して均等強度のチューブフイルムを形成するものである。
【０００４】
本発明は、下方向から供給する帯状フイルムを、断面筒形プレートの内面に沿って運搬してチューブ化する装置であって、前記筒形プレートにおける前記フイルムの入り口側両側面に、前記フイルムの進行方向に登坂状の傾斜縁を形成する一方、前記傾斜縁に続いて前記断面筒形プレートの上面に V 字形縁を形成すると共に、前記 V 字形縁に続く筒形プレートの襟重ね部における下側襟重ね部の下を移動する前記フイルムの一側縁を、同襟重ね部の上を移動するフイルム他側縁と重ね合わすために、同下側襟重ね部の一部を盗み欠きくと共に、前記盗み欠き部後方の前記下側襟重ね部からバネ片を後部に向けて突き出し、該バネ片の下面に米粒状のハンマー台を形成する一方、前記ハンマー台と対向するハンマーに対して超音波振動衝撃を加えて、前記チューブフイルムの襟重ね部分を溶着するように構成する。
【０００６】
【発明の実施形態】
図１及びそれを斜めに見た図２のごとく、断面筒形に折り曲げたプレート１５は、その両側縁１６．１７を着物の襟のごとく上下で重ね合せると共に、帯状フイルム１８の進入口１９には、該フイルムの抵抗を少なくするために傾斜縁２０とV字形縁２１とを形成する。このため該筒形プレート１５に沿って引き出されるフイルム１８の一側の縁２２は内側の側縁１６の下に潜り、他側縁２３は外側縁１７の下に潜る。ただこの場合プレートの内側縁一部を盗み欠き２４しているので、フイルムの一側縁２２はこの盗み欠き部分２４から上に導き出される結果、両側縁２２a．２３aは前記の盗み欠き部分から出た位置で着物の襟重ねのように２枚重ねされる(図４をも参照のこと)。
【０００７】
また前記の筒形プレートにおける内側の側縁１６の中央部に内面に短冊形のバネ片３０を固定し、該バネ片他端の開放端に米粒形のハンマー台３１を膨出すると共に、図４のごとく該ハンマー台３１に超音波ハンマー３２を対向して設置する。そこで前記ハンマー３２の超音波振動をフイルムを通してハンマー台３１に作用させると、かかる振動により発生する熱によってフイルムはチューブ状に溶着される。この場合前記バネ片３０には撓みがあり、フイルム１８に微妙な厚みの誤差があつても前記の撓みによつてフイルムに対する振動衝撃は平均に加わり、フイルムの溶着強度を平均化する。
【０００８】
なお図１ないし図４の実施例は、下方向から引き出した帯状フイルム１８を筒形プレート１５によつてチューブ化するごとく説明したが、筒形フイルムを１８０度回転してフイルムを上方向から導き入れることは可能であり、これは下記の実施例でも逆使用可能なことに当てはまる。
【０００９】
図５および図６に示すごとく機台４０に固定した筒形プレート４１は下面中央に連続的なスリツト４２を形成し、帯状フイルム４３は上方から導かれて、その両側縁４４を合掌状に前記スリツト４２から食み出しながら丸められる。
【００１０】
前記筒形プレートの下面には前記スリツト４２を隔て一側に基礎材４５を垂設し、該基礎材に短冊状のバネ片４６の一端を固定すると共に、該バネ片の多端にハンマー台４７を膨出する一方、機台４８に支持したベルクランク４９のハンマー５０を前記ハンマー台４７に対向させ、前記ベルクランクを振動機５１に連結する。そこで前記振動機５１の動力でハンマー５０を介してハンマー台４７に振動を作用させると、スリット４２から食み出て移動するフイルム合掌部は連続的に溶着される。
【００１１】
なお前記基礎材４５は筒形プレート４１でなく機台に不動の状態で固定しても目的は達成することは可能で、また図１と図６との両実施例それぞれのバネ片は、それがバネ専用材を使用したものでなくとも、ハンマーの振幅は僅かであるから、その振幅によって変形しない程度の弾力を備える材料によつて構成が可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for rolling a strip-like film into a tube along a longitudinal direction and welding the overlapping side edges of the tube film by ultrasonic vibration in order to form a large number of bags for packaging.
[0002]
[Prior art issues]
As shown in FIG. 7, a conventional apparatus for welding overlapping portions of both side edges of a film rounded into a cylindrical shape by a heat generated by ultrasonic vibration and a hammer base 12 fixed to a machine base 11 are shown. The two stacked films 13 are moved in the direction of the arrow 14 between them and the film 13 is continuously welded by the vibrational heat applied from the hammer, but there is a slight difference in the thickness of the film 13. Therefore, the welding strength differs in each region, and air leakage may occur, for example, when vacuum packaging is performed.
[0003]
【the purpose】
Accordingly, the present invention averages the vibration and impact force on the film to form a tube film with uniform strength.
[0004]
The present invention is an apparatus for transporting a strip-like film supplied from below along the inner surface of a cross-sectional cylindrical plate to form a tube, on both side surfaces of the inlet side of the film in the cylindrical plate, While forming an uphill-like inclined edge in the advancing direction, a V- shaped edge is formed on the upper surface of the cross-sectional cylindrical plate following the inclined edge, and a lower portion in a collar overlap portion of the cylindrical plate following the V- shaped edge. In order to overlap one side edge of the film moving under the side collar overlap part with the other side edge of the film moving over the same collar overlap part, and stealing a part of the lower collar overlap part A spring piece projecting toward the rear from the lower collar overlap portion behind the stealing portion and forming a rice-shaped hammer base on the lower surface of the spring piece, while being superfluous to the hammer facing the hammer base Apply sonic vibration shock , Configured to weld the collar overlapping portion of the tube film.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1 and FIG. 2 in an oblique view, the plate 15 folded into a cylindrical cross section has its both side edges 16.17 overlapped vertically like a kimono collar, and at the entrance 19 of the belt-like film 18. Forms an inclined edge 20 and a V-shaped edge 21 to reduce the resistance of the film. Therefore, one side edge 22 of the film 18 drawn out along the cylindrical plate 15 lies under the inner side edge 16, and the other side edge 23 lies under the outer edge 17. In this case, however, the inner edge portion of the plate is notched 24, so that one side edge 22 of the film is led up from the notched portion 24, so that both side edges 22a. Two pieces 23a are piled up like a kimono collar pile at the position which protruded from the said notch part (refer also FIG. 4).
[0007]
Further, a strip-shaped spring piece 30 is fixed to the inner surface at the center of the inner side edge 16 of the cylindrical plate, and a rice grain-shaped hammer base 31 bulges at the open end of the other end of the spring piece. As shown in FIG. 4, an ultrasonic hammer 32 is installed facing the hammer base 31. When the ultrasonic vibration of the hammer 32 is applied to the hammer base 31 through the film, the film is welded in a tube shape by the heat generated by the vibration. In this case, the spring piece 30 is bent, and even if there is a slight thickness error in the film 18, the vibration impact on the film is added to the average due to the bending, and the welding strength of the film is averaged.
[0008]
In the embodiment shown in FIGS. 1 to 4, the strip-shaped film 18 drawn from the lower direction is described as being formed into a tube by the cylindrical plate 15. However, the cylindrical film is rotated 180 degrees to guide the film from the upper direction. It is possible that this can be included, and this applies to the reverse use in the examples below.
[0009]
As shown in FIGS. 5 and 6, the cylindrical plate 41 fixed to the machine base 40 forms a continuous slit 42 at the center of the lower surface, and the belt-like film 43 is guided from above, and both side edges 44 are formed in the shape of a palm. Rolled out from the slit 42.
[0010]
On the lower surface of the cylindrical plate, a base material 45 is suspended from one side of the slit 42, and one end of a strip-shaped spring piece 46 is fixed to the base material, and a hammer base 47 is attached to multiple ends of the spring piece. On the other hand, the hammer 50 of the bell crank 49 supported on the machine base 48 is opposed to the hammer base 47 and the bell crank is connected to the vibrator 51. Therefore, when vibration is applied to the hammer base 47 via the hammer 50 with the power of the vibrator 51, the film palm portion that protrudes and moves from the slit 42 is continuously welded.
[0011]
The object can be achieved even if the base material 45 is fixed to the machine base in an immobile state instead of the cylindrical plate 41, and the spring pieces of both the embodiments of FIGS. However, even if the material for the spring is not used, the amplitude of the hammer is small, so that it can be constituted by a material having elasticity that is not deformed by the amplitude.
