ところで、近年、技術の進歩やコスト低減などの理由から包装フィルムが薄膜化されている。例えば、最近、６０μｍの包装フィルムが袋などの製造に利用されている。そして、このように薄い包装フィルムが通常の超音波溶着機により超音波溶着されると、溶着箇所の溶着強度が不均一になる傾向がある。これは、おそらくホーンとアンビルとの端面精度や、ホーンとアンビルとの噛み合わせ精度が低く、包装フィルムに均一な圧力が付与されていないことに起因するものと考えられる。したがって、上記精度を改善すれば、溶着箇所の溶着強度を均一にすることができるものと期待される。   Incidentally, in recent years, packaging films have been made thinner for reasons such as technological progress and cost reduction. For example, recently, a 60 μm packaging film has been used for manufacturing bags and the like. And when such a thin packaging film is ultrasonically welded by a normal ultrasonic welding machine, the welding strength at the welded portion tends to be non-uniform. This is probably due to the fact that the end face accuracy between the horn and the anvil and the meshing accuracy between the horn and the anvil are low, and no uniform pressure is applied to the packaging film. Therefore, if the accuracy is improved, it is expected that the welding strength at the welding location can be made uniform.

しかし、上記精度の改善には、ホーンやアンビルの精密加工や精密位置合わせなどが必要となり、多額のコストが必要となることが想定される。また、そのようにホーンやアンビルの精密加工や精密位置合わせをうまく実現することができたとしても、超音波溶着操作を繰り返す度にその精度が狂ってくることが容易に想定される。そうすると、ホーンやアンビルの精密加工や精密位置合わせが度々必要となり、袋の生産性に悪影響を及ぼすことが懸念される。   However, the improvement of the accuracy requires precise processing and alignment of the horn and anvil, and it is assumed that a large cost is required. Moreover, even if precision processing and precise positioning of the horn and anvil can be successfully realized as described above, it is easily assumed that the accuracy will be lost every time the ultrasonic welding operation is repeated. This often requires precision processing and alignment of the horn and anvil, which may adversely affect the productivity of the bag.

本発明の課題は、ホーンやアンビルの精密加工や精密な位置合わせを必要とすることなく、薄い溶着フィルムからでも安定した溶着強度を示す袋などを製造することができる超音波溶着方法および超音波溶着機を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide an ultrasonic welding method and an ultrasonic wave capable of manufacturing a bag showing stable welding strength even from a thin welding film without requiring precision processing and precise positioning of a horn or anvil. It is to provide a welding machine.

第１発明に係る超音波溶着方法は、ホーンおよびアンビルを有する超音波溶着機を用いて被溶着物を超音波溶着する超音波溶着方法である。なお、ここにいう「ホーン」とは振動側の金具であり、「アンビル」とは、その受け金具である。そして、この超音波溶着方法では、被溶着物とホーンとの間および被溶着物とアンビルとの間の少なくとも一方の間に緩衝材が挟まれながらホーンとアンビルとにより被溶着物が超音波溶着される。なお、ここにいう「緩衝材」は、特に限定されないが、例えば、紙や、木製シート、フッ素樹脂シート、シリコーンシート、ポリイミドシートなど、溶着対象物の超音波溶着時に溶着対象物に溶着しないような素材であるのが好ましい。また、確かでないが、この緩衝材は圧力および超音波の両方を緩衝する作用があると想定される。また、ここにいう「被溶着物」とは、例えば、包装フィルムなどである。   The ultrasonic welding method according to the first invention is an ultrasonic welding method in which an object to be welded is ultrasonically welded using an ultrasonic welding machine having a horn and an anvil. Here, the “horn” is a vibration-side metal fitting, and the “anvil” is the receiving metal fitting. In this ultrasonic welding method, the welded material is ultrasonically welded by the horn and the anvil while the buffer material is sandwiched between at least one of the welded material and the horn and between the welded material and the anvil. Is done. The “buffer material” here is not particularly limited, but for example, it does not weld to the object to be welded during ultrasonic welding of the object to be welded, such as paper, a wooden sheet, a fluororesin sheet, a silicone sheet, and a polyimide sheet. Preferably, the material is the same. In addition, although not certain, it is assumed that this buffer material has an action of buffering both pressure and ultrasonic waves. Further, the “welded object” referred to here is, for example, a packaging film.

このように被溶着物とホーンとの間および被溶着物とアンビルとの間の少なくとも一方の間に緩衝材が挟まれると、ホーンとアンビルとの端面精度や、ホーンとアンビルとの噛み合わせ精度が低くても、被溶着物に適度に均一な圧力を付与しながら被溶着物を超音波溶着して袋などを製造することができる。このため、この超音波溶着方法では、ホーンやアンビルの精密加工や精密な位置合わせを必要とすることなく、薄い溶着フィルムからでも安定した溶着強度を示す袋などを製造することができる。
第２発明に係る超音波溶着方法は、第１発明に係る超音波溶着方法であって、緩衝材は、ホーンおよびアンビルの少なくとも一方の先端に装着される。
このため、この超音波溶着方法では、緩衝材の使用量を必要最小限にすることができる。 In this way, when the cushioning material is sandwiched between at least one of the object to be welded and the horn and between the object to be welded and the anvil, the end face accuracy between the horn and the anvil, and the meshing accuracy between the horn and the anvil. Even when the temperature is low, a bag or the like can be manufactured by ultrasonically welding the welded material while applying a moderately uniform pressure to the welded material. For this reason, in this ultrasonic welding method, a bag or the like showing stable welding strength can be manufactured even from a thin welding film without requiring precision processing or precise positioning of a horn or anvil.
The ultrasonic welding method according to the second invention is the ultrasonic welding method according to the first invention, wherein the cushioning material is attached to at least one tip of the horn and the anvil.
For this reason, in this ultrasonic welding method, the amount of use of the buffer material can be minimized.

第３発明に係る超音波溶着方法は、第２発明に係る超音波溶着方法であって、緩衝材は、ホーンおよびアンビルの少なくとも一方の先端に着脱可能に装着される。
このため、この超音波溶着方法では、緩衝材が繰り返し使用により劣化する場合であっても、緩衝材を容易に交換することができる。
第４発明に係る超音波溶着方法は、第１発明に係る超音波溶着方法であって、緩衝材は、被溶着物に脱着可能に付着されている。
このため、この超音波溶着方法では、常に新たな緩衝材が使用されることになる。したがって、この超音波溶着方法では、緩衝材の劣化を考慮せずに済む。 The ultrasonic welding method according to the third invention is the ultrasonic welding method according to the second invention, wherein the cushioning material is detachably attached to the tip of at least one of the horn and the anvil.
For this reason, in this ultrasonic welding method, even when the buffer material is deteriorated by repeated use, the buffer material can be easily replaced.
An ultrasonic welding method according to a fourth invention is the ultrasonic welding method according to the first invention, and the buffer material is detachably attached to the object to be welded.
For this reason, a new buffer material is always used in this ultrasonic welding method. Therefore, in this ultrasonic welding method, it is not necessary to consider the deterioration of the buffer material.

The anvil is provided to face the horn. The cushioning material is attached to the tip of at least one of the horn and the anvil.

このため、この超音波溶着機では、ホーンとアンビルとの端面精度や、ホーンとアンビルとの噛み合わせ精度が低くても、被溶着物に適度に均一な圧力を付与しながら被溶着物を超音波溶着して袋などを製造することができる。したがって、この超音波溶着機では、ホーンやアンビルの精密加工や精密な位置合わせを必要とすることなく、薄い溶着フィルムからでも安定した溶着強度を示す袋などを製造することができる。
また、この超音波溶着機では、ホーンおよびアンビルの少なくとも一方の先端に緩衝材が装着されるため、緩衝材の使用量を必要最小限にすることができる。
第６発明に係る超音波溶着機は、第５発明に係る超音波溶着機であって、緩衝材は、ホーンおよびアンビルの少なくとも一方の先端に着脱可能に装着される。
このため、この超音波溶着機では、緩衝材が繰り返し使用により劣化する場合であっても、緩衝材を容易に交換することができる。 For this reason, in this ultrasonic welding machine, even if the end face accuracy of the horn and the anvil and the meshing accuracy of the horn and the anvil are low, the welding object is superposed while applying an appropriate uniform pressure to the welding object. A bag etc. can be manufactured by sonic welding. Therefore, with this ultrasonic welding machine, a bag or the like that exhibits stable welding strength can be manufactured even from a thin welding film without requiring precision processing and precise positioning of the horn or anvil.
Moreover, in this ultrasonic welding machine, since the buffer material is attached to the tip of at least one of the horn and the anvil, the use amount of the buffer material can be minimized.
An ultrasonic welder according to a sixth aspect of the present invention is the ultrasonic welder according to the fifth aspect of the present invention, wherein the cushioning material is detachably attached to the tip of at least one of the horn and the anvil.
For this reason, in this ultrasonic welding machine, even when the buffer material is deteriorated by repeated use, the buffer material can be easily replaced.

The film feeding unit feeds out the film. The ultrasonic welding mechanism has a horn, an anvil, and a buffer material. The anvil is provided to face the horn. The cushioning material is attached to the tip of at least one of the horn and the anvil. And this ultrasonic welding mechanism produces a bag by ultrasonically welding a film with a horn and an anvil.

このため、この包装機では、ホーンとアンビルとの端面精度や、ホーンとアンビルとの噛み合わせ精度が低くても、被溶着物に適度に均一な圧力を付与しながら被溶着物を超音波溶着して袋を製造することができる。したがって、この包装機では、ホーンやアンビルの精密加工や精密な位置合わせを必要とすることなく、薄い溶着フィルムからでも安定した溶着強度を示す袋を製造することができる。
また、この包装機では、ホーンおよびアンビルの少なくとも一方の先端に緩衝材が装着されるため、緩衝材の使用量を必要最小限にすることができる。 For this reason, in this packaging machine, even if the end face accuracy between the horn and the anvil and the engagement accuracy between the horn and the anvil are low, the welding object is ultrasonically welded while applying an appropriate uniform pressure to the welding object. The bag can be manufactured. Therefore, in this packaging machine, a bag showing a stable welding strength can be manufactured even from a thin welding film without requiring precision processing and precise positioning of the horn or anvil.
Moreover, in this packaging machine, since the shock absorbing material is attached to at least one tip of the horn and the anvil, the amount of the shock absorbing material used can be minimized.

The vertical welding mechanism includes a first horn, a first anvil, and a first cushioning material. The first anvil is provided to face the first horn. The first cushioning material is attached to the tip of at least one of the first horn and the first anvil. And this longitudinal welding mechanism ultrasonically welds the both ends of the width direction of a film with a 1st horn and a 1st anvil, and produces a cylindrical film continuously. The horizontal welding mechanism includes a second horn, a second anvil, and a second cushioning material. The second anvil is provided to face the second horn. The second cushioning material is attached to the tip of at least one of the second horn and the second anvil. And this horizontal welding mechanism ultrasonically welds a cylindrical film along the direction which cross | intersects the axial direction of a cylindrical film with a 2nd horn and a 2nd anvil, and produces a bag.

このため、この包装機では、縦溶着機構により連続的に筒状フィルムを作製しつつ商品をその筒状フィルムに投入し、横溶着機構により密閉袋を作製すると共に次の商品を受けるための受け底を筒状フィルムに形成することができる。   For this reason, in this packaging machine, while a cylindrical film is continuously produced by a vertical welding mechanism, a product is put into the cylindrical film, a sealed bag is produced by a horizontal welding mechanism, and a receiver for receiving the next product is received. The bottom can be formed into a tubular film.

The cushioning material is arranged such that a part thereof is inserted between at least one of the film and the horn and between the film and the anvil. The drive unit drives the buffer material so that the buffer material passes between at least one of the film and the horn and between the film and the anvil. The buffer material may be continuously driven or intermittently driven.

Further, it is preferable that the cushioning material is driven when a gap is generated between the film and the horn and between the film and the anvil. Further, the cushioning material may be a sheet shape or an endless belt shape.

この包装機では、この超音波溶着機構がフィルムを超音波溶着して袋を連続的に作製している間であってフィルムとホーンとの間およびフィルムとアンビルとの間に隙間が生じたとき等に、緩衝材駆動機構が緩衝材を駆動させる。このため、この包装機では、一定の期間、常に新たな緩衝材が使用されることになる。したがって、この包装機では、一定の期間、緩衝材の劣化を考慮せずに済む。   In this wrapping machine, when this ultrasonic welding mechanism ultrasonically welds the film to continuously produce the bag, and there is a gap between the film and the horn and between the film and the anvil. For example, the buffer material driving mechanism drives the buffer material. For this reason, in this packaging machine, a new cushioning material is always used for a certain period. Therefore, in this packaging machine, it is not necessary to consider the deterioration of the buffer material for a certain period.

チューブ１３ａは、上端及び下端のいずれもが開口している円筒形状の部材である。そして、このチューブ１３ａには、図２に示されるように、計量機２（図１参照）で計量された所定量の被包装物Ｐ（例えば、ポテトチップス等）が投入される。なお、投入された被包装物Ｐは、チューブ１３ａ内を通ってチューブ１３ａの下端から、封止前の袋Ｂ内へと排出される。   The tube 13a is a cylindrical member that is open at both the upper and lower ends. Then, as shown in FIG. 2, a predetermined amount of an object to be packaged P (for example, potato chips or the like) measured by the weighing machine 2 (see FIG. 1) is put into the tube 13 a. The input package P is discharged from the lower end of the tube 13a into the bag B before sealing through the tube 13a.

As shown in FIGS. 3 and 4, the vertical seal mechanism 15 mainly includes a horn 15a, an anvil 15b, and an ultrasonic generator. (Not shown) and a slide substrate (not shown).

ホーン１５ａは、略柱状の金属成形体であって、基端側に超音波発生器が取り付けられており、超音波発生器により超音波振動する。なお、このホーン１５ａの先端には、緩衝材として紙Ｃが両面テープで付されている。   The horn 15a is a substantially columnar metal molded body, and an ultrasonic generator is attached to the base end side, and is ultrasonically vibrated by the ultrasonic generator. Note that a paper C as a cushioning material is attached to the tip of the horn 15a with a double-sided tape.

アンビル１５ｂは、円柱状の金属成形体であって、側面がホーン１５ａの先端面に対向するように配置されている。なお、本実施の形態において、このアンビル１５ｂは、スライド基板に回転自在に取り付けられており、スライド基板がスライドすることにより、ホーン１５ａに接触するまで直進移動することができるようになっている。なお、スライド基板は、エアシリンダや油圧シリンダ等によりスライドされる。また、アンビル１５ｂの回転軸は、円柱軸に一致する。また、このアンビル１５ｂの側面には、緩衝材として紙Ｃが両面テープで付されている。   The anvil 15b is a cylindrical metal molded body, and is disposed so that the side surface faces the tip surface of the horn 15a. In the present embodiment, the anvil 15b is rotatably attached to the slide substrate, and the slide substrate can slide to move straight until it contacts the horn 15a. The slide substrate is slid by an air cylinder, a hydraulic cylinder, or the like. The rotation axis of the anvil 15b coincides with the cylinder axis. Further, a paper C as a cushioning material is attached to the side surface of the anvil 15b with a double-sided tape.

なお、この縦シール機構１５では、ホーン１５ａ付与される超音波の振幅や、ホーン１５ａに対するアンビル１５ｂの押し付け圧力などが制御装置によって制御される。

横シール機構１６は、筒状フィルムＦｍを横方向にシールして袋Ｂの上下を封止するための機構であって、図２及び図５に示されるように、主に、第１横シール部１６Ａ及び第２横シール部１６Ｂから構成されており、チューブ１３ｂの下端よりも下側に配置されている。   The horizontal sealing mechanism 16 is a mechanism for sealing the cylindrical film Fm in the horizontal direction to seal the upper and lower sides of the bag B. As shown in FIG. 2 and FIG. It is comprised from the part 16A and the 2nd horizontal seal part 16B, and is arrange | positioned below the lower end of the tube 13b.

第１横シール部１６Ａは図５に示されるように主に軸１６ｃ、ホーン５１ａ、超音波発生器（図示せず）及び連結部１６ｂから構成されており、第２横シール部１６Ｂは図５に示されるように主に軸１６ｃ、アンビル５１ｂ及び連結部１６ｂから構成されている。
軸１６ｃは、柱状の部材であって、図示しない駆動機構によって自転および前後移動が可能となっている。 As shown in FIG. 5, the first horizontal seal portion 16A mainly includes a shaft 16c, a horn 51a, an ultrasonic generator (not shown), and a connecting portion 16b. The second horizontal seal portion 16B is shown in FIG. As shown in FIG. 4, the shaft 16c, the anvil 51b, and the connecting portion 16b are mainly configured.
The shaft 16c is a columnar member, and can rotate and move back and forth by a drive mechanism (not shown).

ホーン５１ａは、図６に示されるように、側面から突起する突起部を有する略柱状の金属成形体であって、突起部の裏側に超音波発生器が取り付けられており、超音波発生器により超音波振動する。なお、このホーン５１ａの先端には、緩衝材として紙Ｃが両面テープで付されている。   As shown in FIG. 6, the horn 51a is a substantially columnar metal molded body having a protruding portion protruding from a side surface, and an ultrasonic generator is attached to the back side of the protruding portion. Vibrates ultrasonically. In addition, the paper C is attached to the front-end | tip of this horn 51a with a double-sided tape as a buffering material.

アンビル５１ｂは、図６に示されるように、略柱状の金属成形体であって、ホーン５１ａの突起部に嵌合する凹部を側面に有する。なお、このアンビル５１ｂの凹部の底面には、緩衝材として紙Ｃが両面テープで付されている。   As shown in FIG. 6, the anvil 51 b is a substantially columnar metal formed body, and has a recess on the side surface that fits into the protrusion of the horn 51 a. Note that a paper C as a cushioning material is attached to the bottom surface of the concave portion of the anvil 51b with a double-sided tape.

そして、ホーン５１ａ及びアンビル５１ｂは、図５及び図６に示されるように、前後に並んで配置されており、図５中の符号ｒ２で示される位置において、縦シール機構１５を通過した筒状フィルムＦｍを前側と後側とから挟み込んで筒状フィルムＦｍを横方向に超音波溶着する。本実施の形態では、このようにして被包装物Ｐが詰め込まれた袋Ｂの上側が封止される。なお、ここで、横方向とは、左側または右側へと向かう方向である。   As shown in FIGS. 5 and 6, the horn 51a and the anvil 51b are arranged side by side in the front-and-rear direction, and at the position indicated by reference numeral r2 in FIG. The film Fm is sandwiched from the front side and the rear side, and the tubular film Fm is ultrasonically welded in the lateral direction. In the present embodiment, the upper side of the bag B packed with the article P to be packaged in this way is sealed. Here, the lateral direction is a direction toward the left side or the right side.

連結部１６ｂは、第１横シール部１６Ａにおいてホーン５１ａと軸１６ｃとを連結しており、第２横シール部１６Ｂにおいてアンビル５１ｂと軸１６ｃとを連結している。   The connecting portion 16b connects the horn 51a and the shaft 16c in the first horizontal seal portion 16A, and connects the anvil 51b and the shaft 16c in the second horizontal seal portion 16B.

そして、この横シール機構１６では、ホーン５１ａ及びアンビル５１ｂは所定の位置ｒ１から互いに反対側へと円弧軌道Ｔ２を描きながら所定の位置ｒ２まで移動する。なお、所定の位置ｒ２は、チューブ１３ａの下端よりも下側にある。その後、ホーン５１ａ及びアンビル５１ｂは、筒状フィルムＦｍを超音波溶着しながら、直線軌道Ｔ１に沿って所定の位置ｒ１まで移動する。このとき、横方向にシールされた筒状フィルムＦｍが下側に移動させられる。そして、ホーン５１ａ及びアンビル５１ｂは、所定の位置ｒ１を通過すると、互いに離間して筒状フィルムＦｍを開放する。その後、溶着箇所は、アンビル５１ｂに取り付けられたカッターにより、縦方向中央付近で切断される。この横シール機構１６の一連の動作により、袋Ｂが作製される。   In the lateral seal mechanism 16, the horn 51a and the anvil 51b move from the predetermined position r1 to the predetermined position r2 while drawing the circular arc trajectory T2 from the opposite side to each other. The predetermined position r2 is below the lower end of the tube 13a. Thereafter, the horn 51a and the anvil 51b move to the predetermined position r1 along the linear trajectory T1 while ultrasonically welding the tubular film Fm. At this time, the tubular film Fm sealed in the lateral direction is moved downward. And if the horn 51a and the anvil 51b pass predetermined position r1, it will mutually space apart and will open the cylindrical film Fm. Then, the welding location is cut in the vicinity of the center in the vertical direction by a cutter attached to the anvil 51b. The bag B is produced by a series of operations of the lateral seal mechanism 16.

なお、直線軌道Ｔ１は、横シール部１６Ａ，１６Ｂに属する軸１６ｃがそれぞれ自転しながら互いに反対側へ移動することで形成される。また、円弧軌道Ｔ２は、軸１６ｃの自転のみで形成される。
３．制御装置 The linear track T1 is formed by the shafts 16c belonging to the lateral seal portions 16A and 16B moving to opposite sides while rotating. Further, the circular arc trajectory T2 is formed only by the rotation of the shaft 16c.
3. Control device

制御装置は、計量機２の制御および製袋包装機３の制御を行うものであって、ＣＰＵ、ＲＯＭ、ＲＡＭなどから構成されている。この制御装置は、操作スイッチ類７やタッチパネル式ディスプレイ８（図１参照）から入力される入力値に従って、フィルム供給ユニット６の送出モータや製袋包装ユニット５の各機構の駆動部分などを制御する。また、制御装置は、計量機２および製袋包装機３に設置されている各種センサから必要な情報を取り込み、その情報を各種制御において利用する。
＜実施例＞
以下、実施例を用いて本発明を詳細に説明する。 The control device controls the weighing machine 2 and the bag making and packaging machine 3, and includes a CPU, a ROM, a RAM, and the like. This control device controls a drive motor of the feed motor of the film supply unit 6 and each mechanism of the bag making and packaging unit 5 according to input values input from the operation switches 7 and the touch panel display 8 (see FIG. 1). . Further, the control device takes in necessary information from various sensors installed in the weighing machine 2 and the bag making and packaging machine 3, and uses the information in various controls.
<Example>
Hereinafter, the present invention will be described in detail using examples.

図１３に示されるように、ホーン１５１ａとフィルムＦ１１との間、アンビル１５１ｂとフィルムＦ１２との間に紙Ｃを挟んだ状態で、ホーン１５１ａとアンビル１５１ｂとによりフィルムＦ１１とフィルムＦ１２とを超音波溶着させて試験片を作製した。なお、本実施例では、図１３に示されるように、アンビル１５１ｂが５本歯を有する形状をしている。このため、フィルムＦ１１とフィルムＦ１２とは、長手方向に５箇所で超音波溶着されることになる。また、本実施例においてフィルムＦ１１，Ｆ１２の厚みはそれぞれ６０μｍであり、紙Ｃの厚みは１００〜１２０μｍであった。
そして、図１４に示されるように、この試験片を引張試験機２０にセットして試験片の剥離強度（溶着強度）を測定した。 As shown in FIG. 13, with the paper C sandwiched between the horn 151a and the film F11 and between the anvil 151b and the film F12, the film F11 and the film F12 are ultrasonically transmitted by the horn 151a and the anvil 151b. A test piece was prepared by welding. In this embodiment, as shown in FIG. 13, the anvil 151b has a shape having five teeth. For this reason, the film F11 and the film F12 are ultrasonically welded at five locations in the longitudinal direction. Further, in this example, the thicknesses of the films F11 and F12 were 60 μm, and the thickness of the paper C was 100 to 120 μm.
And as FIG. 14 shows, this test piece was set to the tensile tester 20, and the peeling strength (welding strength) of the test piece was measured.

なお、引張試験機２０は、図１４に示されるように、主に、クロスヘッド２４、ロードセル２３、カップラー２２、上側チャック２１ｂ及び下側チャック２１ａから構成されている。本実施例では、下側チャック２１ａに試験片の下側のフィルムＦ１２を把持させ、上側チャック２１ｂに試験片の上側のフィルムＦ１１を把持させた後、クロスヘッド２４を一定速度で上昇させ、その間に試験片にかかる荷重をロードセル２３で計測した。なお、図１４中の符号ＭＰはフィルムＦ１１，Ｆ１２の溶着箇所を示している。   As shown in FIG. 14, the tensile testing machine 20 mainly includes a cross head 24, a load cell 23, a coupler 22, an upper chuck 21b, and a lower chuck 21a. In this embodiment, the lower chuck 21a grips the lower film F12 of the test piece and the upper chuck 21b grips the upper film F11 of the test piece, and then the cross head 24 is raised at a constant speed. The load applied to the test piece was measured with the load cell 23. In addition, the code | symbol MP in FIG. 14 has shown the welding location of the films F11 and F12.

なお、本実施例では、３つの試験片それぞれについて剥離試験（＜試験条件＞試験片の幅：１５ｍｍ，剥離速度（クロスヘッドの上昇スピード：３００ｍｍ／ｍｉｎ，最大剥離強度５０Ｎ）を行った。その結果を図９に示す。図９に示されるように、３つの試験片の剥離強度は、非常に均一なものとなっている。また、試験片の部分断面写真を図１１に示す。図１１から明らかなように、本実施例の試験片の溶着箇所は、非常に滑らかな形状となっている。
（比較例１）
紙Ｃを差し込まなかったこと以外は実施例１と同様にして試験片を作製して剥離試験を行った。 In this example, a peel test (<test condition> test piece width: 15 mm, peel speed (crosshead ascending speed: 300 mm / min, maximum peel strength 50 N)) was performed on each of the three test pieces. The results are shown in Fig. 9. As shown in Fig. 9, the peel strengths of the three test pieces are very uniform, and a partial cross-sectional photograph of the test piece is shown in Fig. 11. As is clear from the above, the welded portion of the test piece of this example has a very smooth shape.
(Comparative Example 1)
A test piece was prepared and a peel test was performed in the same manner as in Example 1 except that the paper C was not inserted.

なお、本比較例では、４つの試験片それぞれについて剥離試験を行った。その結果を図１０に示す。実施例１の剥離試験結果と比較すると、４つの試験片の剥離強度にはかなりバラツキがあった。また、試験片の部分断面写真を図１２に示す。図１２から明らかなように、本比較例の試験片の溶着箇所は、実施例１の試験片の溶着箇所に比べて、非常に薄くなっている。これは、比較例の試験片作製に当たり、圧力が特定の溶着箇所に集中していたことを示すものである。
＜製袋包装機の特徴＞
（１） In this comparative example, a peel test was performed on each of the four test pieces. The result is shown in FIG. Compared with the peel test result of Example 1, the peel strengths of the four test pieces varied considerably. Moreover, the partial cross-sectional photograph of a test piece is shown in FIG. As is apparent from FIG. 12, the weld location of the test piece of this comparative example is much thinner than the weld location of the test piece of Example 1. This indicates that the pressure was concentrated at a specific welding location in preparing the test piece of the comparative example.
<Features of bag making and packaging machine>
(1)

本発明の実施の形態に係る製袋包装機３では、縦シール機構１５および横シール機構１６においてホーン１５ａ，５１ａ及びアンビル１５ｂ，５１ｂに緩衝材として紙Ｃが付され、フィルムＦ及び筒状フィルムＦｍが紙Ｃを介して超音波溶着される。このため、この製袋包装機３では、ホーン１５ａ，５１ａとアンビル１５ｂ，５１ｂとの端面精度や、ホーン１５ａ，５１ａとアンビル１５ｂ，５１ｂとの噛み合わせ精度が低くても、フィルムＦ及び筒状フィルムＦｍに適度に均一な圧力を付与しながらフィルムＦ及び筒状フィルムＦｍを超音波溶着して袋Ｂを製造することができる。したがって、この製袋包装機３では、ホーン１５ａ，５１ａやアンビル１５ｂ，５１ｂの精密加工や精密な位置合わせを必要とすることなく、薄いフィルムＦ，Ｆｍからでも安定した剥離強度（溶着強度）を示す袋Ｂを製造することができる。
（２） In the bag making and packaging machine 3 according to the embodiment of the present invention, the paper C is attached to the horns 15a and 51a and the anvils 15b and 51b as cushioning materials in the vertical sealing mechanism 15 and the horizontal sealing mechanism 16, and the film F and the cylindrical film Fm is ultrasonically welded through the paper C. For this reason, in this bag making packaging machine 3, even if the end face accuracy between the horns 15a and 51a and the anvils 15b and 51b and the meshing accuracy between the horns 15a and 51a and the anvils 15b and 51b are low, the film F and the cylindrical shape The bag B can be manufactured by ultrasonically welding the film F and the tubular film Fm while applying a moderately uniform pressure to the film Fm. Therefore, in this bag making and packaging machine 3, a stable peel strength (welding strength) can be obtained even from the thin films F and Fm without requiring precise processing and precise alignment of the horns 15a and 51a and the anvils 15b and 51b. The bag B shown can be manufactured.

Although ultrasonic welding was performed via the paper C, the film F and the tubular film Fm were ultrasonically welded via the paper C when the paper C was fed out below the film F as shown in FIG. It doesn't matter if it is done. In such a case, it is easy to arrange the paper supply unit on which the paper roll is set below the film supply unit 6.

Then, the drive motor drives the drawing roll 17b at the timing when the paper deteriorates (the signal transmission time interval is set by the control device), and pulls out the paper C from the buffer material roll 17a. In such a case, the cutter is provided on the downstream side of the lateral seal mechanism 16 so as not to cut the paper C.

また、縦シール機構１５においても、上記と同様にして、ホーン１５ａとフィルムＦとの間、アンビル１５ｂとフィルムＦとの間に紙Ｃを繰り出すようにしてもかまわない。
