Description

本発明は、製袋包装機に関する。   The present invention relates to a bag making and packaging machine.

従来、袋を形成しながら、食品等の被包装物をその袋に充填して密閉包装する製袋包装機として、超音波シール方式を用いる製袋包装機が用いられている。この製袋包装機は、シート状のフィルムである包材をフォーマーおよびチューブによって筒状（チューブ状）に成形し、チューブ状の包材の重なり合った縦方向の縁をシールする。そして、被包装物をチューブ状の包材の内部に充填して、超音波シール機構により袋の上部と袋の下部とを横方向に超音波シールした後、シールされた部分の中央をカッターで切断する。   2. Description of the Related Art Conventionally, a bag making and packaging machine using an ultrasonic sealing method has been used as a bag making and packaging machine that forms a bag and fills the bag with an object to be packaged such as food and seals it. This bag making and packaging machine forms a wrapping material, which is a sheet-like film, into a tubular shape (tube shape) with a former and a tube, and seals the overlapping vertical edges of the tubular wrapping material. Then, after filling the inside of the tube-shaped packaging material and ultrasonically sealing the upper part of the bag and the lower part of the bag in the lateral direction by an ultrasonic sealing mechanism, the center of the sealed part is cut with a cutter. Disconnect.

超音波シール機構は、ホーンおよびアンビルによって包材を挟み、ホーンを超音波振動させて包材をシールする。例えば、特許文献１（国際公開第２００７／０１２９１７号）に開示されている超音波シール機構では、一対の回転体のそれぞれにホーンおよびアンビルが取り付けられ、ホーンおよびアンビルは、回転しながら、筒状の包材の搬送方向と直交する方向に沿って包材を挟み込んで超音波シールする。   The ultrasonic sealing mechanism sandwiches the packaging material between the horn and the anvil, and ultrasonically vibrates the horn to seal the packaging material. For example, in the ultrasonic sealing mechanism disclosed in Patent Document 1 (International Publication No. 2007/012917), a horn and an anvil are attached to each of a pair of rotating bodies, and the horn and the anvil are cylindrical while rotating. The packaging material is sandwiched along the direction orthogonal to the conveying direction of the packaging material and ultrasonically sealed.

しかし、従来、ホーンは、ホーン本体と、ホーン本体から延びる複数の支持部とから構成され、複数の支持部は、共通の加圧部材に固定されている。超音波シール機構のシール動作時には、加圧部材の両端部に力を加えることで、ホーンがアンビルに向かって押されて、包材が挟み込まれる。このとき、両端部に加えられる力によって加圧部材が撓むと、支持部を介してホーンの両端部も加圧されて、ホーンも撓む場合がある。その結果、超音波シール機構のシール動作時において、ホーンとアンビルとが接触して、袋のシール性および耐久性が低下するおそれがある。   However, conventionally, a horn is composed of a horn body and a plurality of support portions extending from the horn body, and the plurality of support portions are fixed to a common pressure member. During the sealing operation of the ultrasonic sealing mechanism, a force is applied to both ends of the pressure member, so that the horn is pushed toward the anvil and the packaging material is sandwiched. At this time, if the pressure member is bent by the force applied to both ends, both ends of the horn are also pressed through the support portion, and the horn may be bent. As a result, at the time of the sealing operation of the ultrasonic sealing mechanism, the horn and the anvil may come into contact with each other, and the sealing performance and durability of the bag may be reduced.

本発明の目的は、超音波シールに用いられるホーンとアンビルとの接触を防止することができる製袋包装機を提供することである。   An object of the present invention is to provide a bag making and packaging machine capable of preventing contact between a horn and an anvil used for ultrasonic sealing.

本発明に係る製袋包装機は、チューブ状の包材に被包装物を充填して密封する。この製袋包装機は、超音波シール機構と、ホーン支持体と、加圧部とを備える。超音波シール機構は、ホーンおよびアンビルで包材を挟み、包材に超音波振動を与えて包材を幅方向にシールする。ホーン支持体は、ホーンを支持する。加圧部は、ホーン支持体を加圧して、ホーンをアンビルに向かって押す。ホーンは、ホーン本体と、複数の支持部とを有する。ホーン本体は、アンビルと共に包材を挟む。複数の支持部は、ホーン本体から延び、幅方向に配列される。ホーン支持体は、第１支持部材と、第２支持部材と、連結部材とを有する。第１支持部材は、複数の支持部が固定される。第２支持部材は、加圧部によって両端部が加圧される。連結部材は、第１支持部材の中央部である第１中央部と、第２支持部材の中央部である第２中央部とを連結する。第１中央部は、幅方向の両端の支持部が固定される一対の固定部の間に位置する。   The bag making and packaging machine according to the present invention fills a tube-shaped packaging material with an article to be packaged and seals it. This bag making and packaging machine includes an ultrasonic sealing mechanism, a horn support, and a pressure unit. The ultrasonic sealing mechanism sandwiches the packaging material with a horn and an anvil and applies ultrasonic vibration to the packaging material to seal the packaging material in the width direction. The horn support supports the horn. The pressurizing unit pressurizes the horn support and pushes the horn toward the anvil. The horn has a horn main body and a plurality of support portions. The horn body sandwiches the packaging material with the anvil. The plurality of support portions extend from the horn body and are arranged in the width direction. The horn support includes a first support member, a second support member, and a connecting member. A plurality of support portions are fixed to the first support member. Both ends of the second support member are pressurized by the pressure unit. A connection member connects the 1st center part which is the center part of the 1st support member, and the 2nd center part which is the center part of the 2nd support member. The first center part is located between a pair of fixing parts to which support parts at both ends in the width direction are fixed.

本発明に係る製袋包装機では、ホーン支持体は、ホーン本体から延びる複数の支持部に連結される第１支持部材と、超音波シール時に両端部が加圧される第２支持部材とを有する。第１支持部材は、第２支持部材と連結部材を介して連結されている。超音波シール時にホーンをアンビルに向かって押す際に、第２支持部材の両端部は加圧部によって加圧されるが、第１支持部材は加圧部によって直接加圧されない。そのため、超音波シール時において、第１支持部材は、ホーン支持体の加圧によって撓みにくい。第１支持部材が撓みにくいので、第１支持部材から支持部を介して力が加えられるホーン本体も撓みにくい。そのため、この製袋包装機は、超音波シール時においてホーンの両端部がアンビルと接触することを回避することができる。従って、本発明に係る製袋包装機は、超音波シールに用いられるホーンとアンビルとの接触を防止することができる。   In the bag making and packaging machine according to the present invention, the horn support includes a first support member connected to a plurality of support portions extending from the horn body, and a second support member whose both ends are pressurized during ultrasonic sealing. Have. The first support member is connected to the second support member via a connection member. When pushing the horn toward the anvil during ultrasonic sealing, both end portions of the second support member are pressurized by the pressurizing unit, but the first support member is not directly pressurized by the pressurizing unit. Therefore, at the time of ultrasonic sealing, the first support member is difficult to bend due to pressurization of the horn support. Since the first support member is difficult to bend, the horn body to which force is applied from the first support member via the support portion is also difficult to bend. Therefore, this bag making packaging machine can avoid that the both ends of a horn contact an anvil at the time of ultrasonic sealing. Therefore, the bag making and packaging machine according to the present invention can prevent contact between the horn and the anvil used for ultrasonic sealing.

本発明に係る製袋包装機では、第１中央部は、ホーンおよびアンビルに挟まれている包材よりも小さい幅を有することが好ましい。   In the bag making and packaging machine according to the present invention, the first central portion preferably has a smaller width than the packaging material sandwiched between the horn and the anvil.

本発明に係る製袋包装機は、超音波シールに用いられるホーンとアンビルとの接触を防止することができる。   The bag making and packaging machine according to the present invention can prevent contact between a horn and an anvil used for ultrasonic sealing.

図２は、製袋包装ユニット３の概略的な構成を示す斜視図である。以下の説明において、「前（正面）」、「後（背面）」、「上」、「下」、「左」および「右」からなる６つの方向を、図２に示されるように定義する。 (2) Configuration of Bag Making and Packaging Unit FIG. 2 is a perspective view showing a schematic configuration of the bag making and packaging unit 3. In the following description, six directions consisting of “front (front)”, “rear (back)”, “up”, “down”, “left” and “right” are defined as shown in FIG. .

製袋包装ユニット３は、主として、成形機構１３と、プルダウンベルト機構１４と、縦シール機構１５と、横シール機構１７と、横方向駆動機構５５とから構成される。成形機構１３は、フィルム供給ユニット４から搬送されてくるシート状のフィルムＦを筒状に成形する。プルダウンベルト機構１４は、筒状に成形されたフィルムＦを下方に搬送する。縦シール機構１５は、筒状に成形されたフィルムＦの両端部の重なり部分を、搬送方向と平行な縦方向にシールして、筒状フィルムＦｃを形成する。横シール機構１７は、筒状フィルムＦｃを、搬送方向と直交する横方向にシールして、上端部および下端部が横シールされた袋Ｂを形成する。横方向駆動機構５５は、筒状フィルムＦｃの横シール時に、横シール機構１７を往復運動させる。   The bag making and packaging unit 3 mainly includes a forming mechanism 13, a pull-down belt mechanism 14, a vertical sealing mechanism 15, a horizontal sealing mechanism 17, and a horizontal driving mechanism 55. The forming mechanism 13 forms the sheet-like film F conveyed from the film supply unit 4 into a cylindrical shape. The pull-down belt mechanism 14 conveys the film F formed into a cylindrical shape downward. The vertical sealing mechanism 15 seals the overlapping portion of both end portions of the film F formed into a cylindrical shape in the vertical direction parallel to the transport direction to form the cylindrical film Fc. The horizontal sealing mechanism 17 seals the tubular film Fc in the horizontal direction perpendicular to the transport direction, and forms a bag B in which the upper end and the lower end are horizontally sealed. The lateral drive mechanism 55 reciprocates the lateral seal mechanism 17 when the cylindrical film Fc is laterally sealed.

（２−１）成形機構
成形機構１３は、チューブ１３ａとフォーマ１３ｂとを有する。チューブ１３ａは、上端および下端が開口している、円筒形状の部材である。チューブ１３ａの上端の開口には、組合せ計量ユニット２から供給される被包装物Ｃが投入される。フォーマ１３ｂは、チューブ１３ａを取り囲むように配置されている。フィルム供給ユニット４のフィルムロールから繰り出されてきたフィルムＦは、チューブ１３ａとフォーマ１３ｂとの間の隙間を通過する際に、チューブ１３ａに巻き付いて筒状に成形される。チューブ１３ａおよびフォーマ１３ｂは、製造する袋Ｂの大きさに応じて取り替えることができる。 (2-1) Forming mechanism The forming mechanism 13 includes a tube 13a and a former 13b. The tube 13a is a cylindrical member having an open upper end and a lower end. An article C to be packaged supplied from the combination weighing unit 2 is put into the opening at the upper end of the tube 13a. The former 13b is disposed so as to surround the tube 13a. When the film F fed out from the film roll of the film supply unit 4 passes through the gap between the tube 13a and the former 13b, the film F is wound around the tube 13a and formed into a cylindrical shape. The tube 13a and the former 13b can be replaced according to the size of the bag B to be manufactured.

縦シール機構１５は、筒状に成形されたフィルムＦを縦方向（図２では、上下方向）にシールする。縦シール機構１５は、チューブ１３ａの正面側に配置される。縦シール機構１５は、駆動機構（図示せず）によって、チューブ１３ａに近づくように、あるいは、チューブ１３ａから遠ざかるように前後方向に移動する。 (2-3) Vertical Seal Mechanism The vertical seal mechanism 15 seals the film F formed in a cylindrical shape in the vertical direction (the vertical direction in FIG. 2). The vertical seal mechanism 15 is disposed on the front side of the tube 13a. The vertical seal mechanism 15 is moved in the front-rear direction so as to approach the tube 13a or away from the tube 13a by a drive mechanism (not shown).

縦シール機構１５が駆動機構によってチューブ１３ａに近づくように駆動することで、チューブ１３ａに巻き付いたフィルムＦの縦方向の重なり部分は、縦シール機構１５とチューブ１３ａとの間に挟まれる。縦シール機構１５は、駆動機構によってフィルムＦの重なり部分を一定の圧力でチューブ１３ａに押し付けながら加熱して、フィルムＦの重なり部分を縦方向にシールして、筒状フィルムＦｃを形成する。縦シール機構１５は、フィルムＦの重なり部分を加熱するヒータ、および、フィルムＦの重なり部分と接触するヒータベルト等を有している。   When the vertical seal mechanism 15 is driven by the drive mechanism so as to approach the tube 13a, the vertical overlapping portion of the film F wound around the tube 13a is sandwiched between the vertical seal mechanism 15 and the tube 13a. The vertical sealing mechanism 15 heats the overlapping portion of the film F while pressing it against the tube 13a with a constant pressure by the driving mechanism, and seals the overlapping portion of the film F in the vertical direction to form the cylindrical film Fc. The vertical sealing mechanism 15 includes a heater that heats the overlapping portion of the film F, a heater belt that contacts the overlapping portion of the film F, and the like.

The second anvil 52a is attached at a position 180 degrees away from the first horn 51a with the rotation axis C1 of the first rotating body 50a as the center. The second rotating body 50b is provided with a first anvil 51b and a second horn 52b. The second horn 52b is attached at a position 180 degrees away from the first anvil 51b with the rotation axis C2 of the second rotating body 50b as the center.

図４は、第１回転体５０ａおよび第２回転体５０ｂのホーン５１ａ，５２ｂおよびアンビル５１ｂ，５２ａの軌跡を表す図である。第１回転体５０ａは、駆動モータ（図示せず）によって回転軸Ｃ１を中心に回転する。第２回転体５０ｂは、駆動モータ（図示せず）によって回転軸Ｃ２を中心に回転する。図４において二点鎖線で示されるように、第１ホーン５１ａおよび第２アンビル５２ａは、回転軸Ｃ１を中心にしてＤ字状に旋回し、第１アンビル５１ｂおよび第２ホーン５２ｂは、回転軸Ｃ２を中心にしてＤ字状に旋回する。第１回転体５０ａおよび第２回転体５０ｂの回転によって、筒状フィルムＦｃは、第１ホーン５１ａおよび第１アンビル５１ｂに挟み込まれ、第２ホーン５２ｂおよび第２アンビル５２ａによって挟み込まれる。   FIG. 4 is a diagram illustrating the trajectories of the horns 51a and 52b and the anvils 51b and 52a of the first rotating body 50a and the second rotating body 50b. The first rotating body 50a is rotated around the rotation axis C1 by a drive motor (not shown). The second rotating body 50b is rotated around the rotation axis C2 by a drive motor (not shown). As shown by a two-dot chain line in FIG. 4, the first horn 51a and the second anvil 52a rotate in a D shape around the rotation axis C1, and the first anvil 51b and the second horn 52b rotate about the rotation axis. It turns in a D shape around C2. The cylindrical film Fc is sandwiched between the first horn 51a and the first anvil 51b by the rotation of the first rotator 50a and the second rotator 50b, and is sandwiched between the second horn 52b and the second anvil 52a.

また、図３に示されるように、第１回転体５０ａは、第１水平移動板６１ａに支持され、第２回転体５０ｂは、第２水平移動板６１ｂに支持されている。第１水平移動板６１ａおよび第２水平移動板６１ｂは、横方向駆動機構５５によって、互いに近接または離間するように前後方向に移動する。   As shown in FIG. 3, the first rotating body 50a is supported by the first horizontal moving plate 61a, and the second rotating body 50b is supported by the second horizontal moving plate 61b. The first horizontal moving plate 61a and the second horizontal moving plate 61b are moved in the front-rear direction by the lateral drive mechanism 55 so as to approach or separate from each other.

また、図４に示されるように、横シール機構１７には、フィルム検知センサ５９が取り付けられている。フィルム検知センサ５９は、例えば、光電センサおよび超音波センサである。フィルム検知センサ５９は、第１ホーン５１ａおよび第１アンビル５１ｂ（または、第２ホーン５２ｂおよび第２アンビル５２ａ）によって筒状フィルムＦｃが挟み込まれる直前において、筒状フィルムＦｃの有無を検知する。フィルム検知センサ５９によって筒状フィルムＦｃが存在しないと検知された場合、第１ホーン５１ａと第１アンビル５１ｂとが互いに接触しないように、または、第２ホーン５２ｂと第２アンビル５２ａとが互いに接触しないように、第１回転体５０ａおよび第２回転体５０ｂの回転動作が制御される。   Further, as shown in FIG. 4, a film detection sensor 59 is attached to the lateral seal mechanism 17. The film detection sensor 59 is, for example, a photoelectric sensor or an ultrasonic sensor. The film detection sensor 59 detects the presence or absence of the tubular film Fc immediately before the tubular film Fc is sandwiched between the first horn 51a and the first anvil 51b (or the second horn 52b and the second anvil 52a). When the film detection sensor 59 detects that the tubular film Fc is not present, the first horn 51a and the first anvil 51b are not in contact with each other, or the second horn 52b and the second anvil 52a are in contact with each other.

（３−２）第１ホーンおよび第２ホーンの構成
以下、便宜上、図６に示されるユニットをホーンユニット５１と呼ぶ。ホーンユニット５１は、主として、第１ホーン５１ａと、３つの振動素子５１１と、４つの円柱状の共振体５１３とから構成される。第１ホーン５１ａは、第１アンビル５１ｂと共に筒状フィルムＦｃを挟むホーン本体である。第１ホーン５１ａは、後述するように、ホーン支持体７１によって支持されている。図７は、ホーンユニット５１の平面図である。図８は、図７の線分ＶＩＩＩ−ＶＩＩＩにおける断面図である。図９は、図７の線分ＩＸ−ＩＸにおける断面図である。なお、以下の説明は、第２ホーン５２ｂを有するホーンユニットにも適用可能である。 (3-2) Configuration of First Horn and Second Horn The unit shown in FIG. 6 is referred to as a horn unit 51 for convenience. The horn unit 51 mainly includes a first horn 51a, three vibration elements 511, and four columnar resonators 513. The 1st horn 51a is a horn main body which pinches | interposes the cylindrical film Fc with the 1st anvil 51b. The first horn 51a is supported by a horn support 71 as will be described later. FIG. 7 is a plan view of the horn unit 51. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 9 is a cross-sectional view taken along line IX-IX in FIG. In addition, the following description is applicable also to the horn unit which has the 2nd horn 52b.

３つの振動素子５１１は、第１ホーン５１ａと第２アンビル５２ａとの間において、シール方向に沿って等間隔に配置されるように、第１ホーン５１ａと連結されている。４つの共振体５１３は、第１ホーン５１ａと第２アンビル５２ａとの間において、シール方向に沿って等間隔に配置されるように、第１ホーン５１ａと連結されている。それぞれの振動素子５１１は、その両側を２つの共振体５１３によって挟まれている。すなわち、図７に示されるように、振動素子５１１および共振体５１３は、シール方向に沿って交互に配置されている。   The three vibration elements 511 are connected to the first horn 51a so as to be arranged at equal intervals along the sealing direction between the first horn 51a and the second anvil 52a. The four resonators 513 are connected to the first horn 51a so as to be arranged at equal intervals along the sealing direction between the first horn 51a and the second anvil 52a. Each vibrating element 511 is sandwiched between two resonators 513 on both sides. That is, as illustrated in FIG. 7, the vibration elements 511 and the resonators 513 are alternately arranged along the seal direction.

図８は、共振体５１３の長軸に沿ったホーンユニット５１の断面図である。共振体５１３の長軸方向の中央には、超音波振動の節が位置している。ホーンユニット５１は、この節の近傍を保持しつつ第１回転体５０ａを固定することによって、第１ホーン５１ａを安定して駆動することができる。超音波振動の節の位置において、共振体５１３の外周から径方向に沿って、フランジ５１３ａが突出している。ホーンユニット５１は、フランジ５１３ａを介して第１回転体５０ａを固定する。フランジ５１３ａの外周面は、保持部５１５によって、上下方向の両側から挟まれている。フランジ５１３ａの一方の側面は、保持部５１５と接触し、かつ、他方の側面は、保持板５１９と接触している。すなわち、保持部５１５および保持板５１９は、フランジ５１３ａを挟むように固定している。保持部５１５は、後述する第１支持部材７３に固定されている。   FIG. 8 is a cross-sectional view of the horn unit 51 along the long axis of the resonator 513. A node of ultrasonic vibration is located in the center of the long axis direction of the resonator 513. The horn unit 51 can stably drive the first horn 51a by fixing the first rotating body 50a while holding the vicinity of this node. A flange 513a protrudes along the radial direction from the outer periphery of the resonator 513 at the position of the node of the ultrasonic vibration. The horn unit 51 fixes the first rotating body 50a via the flange 513a. The outer peripheral surface of the flange 513a is sandwiched by the holding portion 515 from both sides in the vertical direction. One side surface of the flange 513a is in contact with the holding portion 515, and the other side surface is in contact with the holding plate 519. That is, the holding part 515 and the holding plate 519 are fixed so as to sandwich the flange 513a. The holding part 515 is fixed to a first support member 73 described later.

図９は、振動素子５１１の長軸に沿ったホーンユニット５１の断面図である。振動素子５１１は、第１ホーン５１ａと連結され、第１ホーン５１ａに超音波振動を伝達する円柱状の伝達体５１１ｂを有する。振動素子５１１の伝達体５１１ｂの長軸方向の中央において、振動素子５１１の外周から径方向に沿って、フランジ５１１ａが突出している。ホーンユニット５１は、フランジ５１１ａを介して第１回転体５０ａを固定する。フランジ５１１ａの外周面は、保持部５２５によって、上下方向の両側から挟まれている。フランジ５１１ａの一方の側面は、保持部５２５と接触し、かつ、他方の側面は、保持板５２９と接触している。すなわち、保持部５２５および保持板５２９は、フランジ５１３ａを挟むように固定している。   FIG. 9 is a cross-sectional view of the horn unit 51 along the long axis of the vibration element 511. The vibration element 511 is connected to the first horn 51a, and includes a columnar transmission body 511b that transmits ultrasonic vibration to the first horn 51a. A flange 511a protrudes from the outer periphery of the vibration element 511 along the radial direction at the center in the major axis direction of the transmission body 511b of the vibration element 511. The horn unit 51 fixes the first rotating body 50a via the flange 511a. The outer peripheral surface of the flange 511a is sandwiched by the holding portion 525 from both sides in the vertical direction. One side surface of the flange 511 a is in contact with the holding portion 525, and the other side surface is in contact with the holding plate 529. That is, the holding part 525 and the holding plate 529 are fixed so as to sandwich the flange 513a.

（３−３）ホーン支持体の構成
次に、ホーンユニット５１の第１ホーン５１ａを支持するホーン支持体７１について説明する。図１０は、ホーンユニット５１に取り付けられたホーン支持体７１の概略的な平面図である。図１０において、ホーン支持体７１は、ハッチングされた領域で示されている。以下の説明は、第２ホーン５２ｂにも適用可能である。 (3-3) Configuration of Horn Support Next, the horn support 71 that supports the first horn 51a of the horn unit 51 will be described. FIG. 10 is a schematic plan view of the horn support 71 attached to the horn unit 51. In FIG. 10, the horn support 71 is shown in the hatched area. The following description is applicable to the second horn 52b.

ホーン支持体７１は、ホーンユニット５１の第１ホーン５１ａに連結されている。ホーン支持体７１は、加圧部７２によって力が加えられる。加圧部７２は、例えば、エアシリンダ等の駆動機構である。図１０において、加圧部７２がホーン支持体７１に加える力は、白抜きの矢印で示されている。第１ホーン５１ａは、ホーン支持体７１を介して加圧部７２から力を受けて、第１アンビル５１ｂに向かって押される。第１ホーン５１ａは、振動素子５１１によって超音波振動する。これにより、第１ホーン５１ａおよび第１アンビル５１ｂによって挟まれている筒状フィルムＦｃに、第１ホーン５１ａから超音波振動が伝達されて、筒状フィルムＦｃが横シールされる。   The horn support 71 is connected to the first horn 51 a of the horn unit 51. A force is applied to the horn support 71 by the pressure unit 72. The pressurizing unit 72 is a drive mechanism such as an air cylinder, for example. In FIG. 10, the force applied by the pressure unit 72 to the horn support 71 is indicated by a white arrow. The first horn 51a receives a force from the pressure unit 72 via the horn support 71 and is pushed toward the first anvil 51b. The first horn 51a is ultrasonically vibrated by the vibration element 511. Thereby, ultrasonic vibration is transmitted from the first horn 51a to the tubular film Fc sandwiched between the first horn 51a and the first anvil 51b, and the tubular film Fc is laterally sealed.

ホーン支持体７１は、図１０に示されるように、主として、第１支持部材７３と、第２支持部材７４と、連結部材７５とから構成される。   As shown in FIG. 10, the horn support 71 is mainly composed of a first support member 73, a second support member 74, and a connecting member 75.

第１支持部材７３は、ホーンユニット５１に連結されている。具体的には、ホーンユニット５１の４つの共振体５１３は、それぞれ、第１支持部材７３に取り付けられて固定されている。すなわち、ホーンユニット５１の第１ホーン５１ａは、４つの共振体５１３を介して、第１支持部材７３と連結されている。しかし、第２支持部材７４および連結部材７５は、ホーンユニット５１と直接連結されていない。   The first support member 73 is connected to the horn unit 51. Specifically, the four resonators 513 of the horn unit 51 are respectively attached and fixed to the first support member 73. That is, the first horn 51 a of the horn unit 51 is connected to the first support member 73 via the four resonators 513. However, the second support member 74 and the connecting member 75 are not directly connected to the horn unit 51.

第２支持部材７４は、加圧部７２によって力が加えられる。図１０に示されるように、加圧部７２は、第２支持部材７４の両端部を第１アンビル５１ｂに向かって押す。すなわち、加圧部７２は、第１ホーン５１ａを第１アンビル５１ｂに向かって移動させて、第１ホーン５１ａおよび第１アンビル５１ｂによって筒状フィルムＦｃを挟み込むための力をホーン支持体７１に与える。   A force is applied to the second support member 74 by the pressure unit 72. As shown in FIG. 10, the pressurizing unit 72 pushes both end portions of the second support member 74 toward the first anvil 51b. That is, the pressurizing unit 72 moves the first horn 51a toward the first anvil 51b and gives the horn support 71 a force for sandwiching the tubular film Fc by the first horn 51a and the first anvil 51b. .

連結部材７５は、第１支持部材７３の中央部である第１中央部７３ａと、第２支持部材７４の中央部である第２中央部７４ａとを連結する。第１中央部７３ａは、第１支持部材７３の幅方向の中央部である。ここで、幅方向は、左右方向、または、図１０に示される第１ホーン５１ａの長手方向である。同様に、第２中央部７４ａは、第２支持部材７４の幅方向の中央部である。第１中央部７３ａは、第１支持部材７３の一対の端部固定部７３ｂの間に位置している。一対の端部固定部７３ｂは、図１０に示されるように、ホーンユニット５１の４つの共振体５１３の内、幅方向において両端に位置している２つの共振体５１３がそれぞれ固定される部分である。第１中央部７３ａは、連結部材７５が連結される部分であるので、連結部材７５の幅方向の寸法は、一対の端部固定部７３ｂにそれぞれ固定される２つの共振体５１３の間の間隔よりも小さい。   The connecting member 75 connects the first central portion 73 a that is the central portion of the first support member 73 and the second central portion 74 a that is the central portion of the second support member 74. The first central portion 73 a is a central portion in the width direction of the first support member 73. Here, the width direction is the left-right direction or the longitudinal direction of the first horn 51a shown in FIG. Similarly, the second central portion 74 a is a central portion in the width direction of the second support member 74. The first central portion 73 a is located between the pair of end portion fixing portions 73 b of the first support member 73. As shown in FIG. 10, the pair of end portion fixing portions 73b are portions to which two resonators 513 located at both ends in the width direction are fixed, respectively, among the four resonators 513 of the horn unit 51. is there. Since the first central portion 73a is a portion to which the connecting member 75 is connected, the dimension of the connecting member 75 in the width direction is the distance between the two resonators 513 fixed to the pair of end fixing portions 73b. Smaller than.

（３−４）電力供給機構の構成
次に、横シール機構１７の電力供給機構について説明する。図５に示されるように、第１回転体５０ａの回転軸Ｃ１の延長上には、第１スリップリング１０１が設けられ、第２回転体５０ｂの回転軸Ｃ２の延長上には、第２スリップリング１０２が設けられている。第１スリップリング１０１および第２スリップリング１０２は、回転する導体と、固定されて回転しない導体との間を、連続的かつ電気的に接続する導電回転リングである。第１スリップリング１０１は、第１回転体５０ａと共に回転する振動素子５１１に電力を供給し、第２スリップリング１０２は、第２回転体５０ｂと共に回転する振動素子５２１に電力を供給する。 (3-4) Configuration of Power Supply Mechanism Next, the power supply mechanism of the lateral seal mechanism 17 will be described. As shown in FIG. 5, a first slip ring 101 is provided on the extension of the rotation axis C1 of the first rotating body 50a, and a second slip is provided on the extension of the rotation axis C2 of the second rotating body 50b. A ring 102 is provided. The first slip ring 101 and the second slip ring 102 are conductive rotating rings that continuously and electrically connect a rotating conductor and a fixed, non-rotating conductor. The first slip ring 101 supplies power to the vibration element 511 that rotates together with the first rotating body 50a, and the second slip ring 102 supplies power to the vibration element 521 that rotates together with the second rotating body 50b.

第１回転体５０ａには、３つのトランス１１１が搭載されている。各トランス１１１は、１つの第１スリップリング１０１と、各振動素子５１１との間を介在する。３つのトランス１１１の一次側の巻き線が直列に接続されて構成された二極に、二極タイプの第１スリップリング１０１を介して電力が供給される。３つのトランス１１１の二次側の巻き線は、各振動素子５１１と対応し、それぞれ独立した駆動電圧が供給される。   Three transformers 111 are mounted on the first rotating body 50a. Each transformer 111 is interposed between one first slip ring 101 and each vibration element 511. Electric power is supplied to the two poles formed by connecting the primary windings of the three transformers 111 in series via the first slip ring 101 of the two-pole type. The secondary windings of the three transformers 111 correspond to the vibration elements 511 and are supplied with independent drive voltages.

３つのトランス１１１は、板状のトランスホルダ１２１に保持されている。トランスホルダ１２１の対向する一対の長辺のそれぞれの中央から、回転軸Ｃ１と平行に、アーム１３１が延びている。２つのアーム１３１の端部は、板状のスリップリングホルダ１４１を両端から挟むように固定している。スリップリングホルダ１４１には、回転軸Ｃ１と同心の孔が設けられている。スリップリングホルダ１４１は、この孔によって、第１スリップリング１０１を保持している。これにより、第１スリップリング１０１を介して、回転しない電源側から、回転する３つのトランス１１１側に電力が供給される。   The three transformers 111 are held by a plate-like transformer holder 121. An arm 131 extends in parallel with the rotation axis C1 from the center of each of the pair of opposing long sides of the transformer holder 121. The ends of the two arms 131 are fixed so as to sandwich the plate-shaped slip ring holder 141 from both ends. The slip ring holder 141 is provided with a hole concentric with the rotation axis C1. The slip ring holder 141 holds the first slip ring 101 through this hole. Thereby, electric power is supplied from the non-rotating power supply side to the rotating three transformers 111 via the first slip ring 101.

図１１は、第１回転体５０ａの第１スリップリング１０１、３つのトランス１１１および３つの振動素子５１１の電気的接続状態の模式図である。３つのトランス１１１の一次側の巻き線が直列に接続されているので、電力が供給される対象は二極となっている。そのため、１つの二極型の第１スリップリング１０１を用いて、回転する３つのトランス１１１に電力を供給することができる。   FIG. 11 is a schematic diagram of an electrical connection state of the first slip ring 101, the three transformers 111, and the three vibration elements 511 of the first rotating body 50a. Since the primary windings of the three transformers 111 are connected in series, the target to which power is supplied is bipolar. Therefore, electric power can be supplied to the three transformers 111 that rotate using one bipolar first slip ring 101.

また、第１回転体５０ａの側と同様に、第２回転体５０ｂの側には、第２スリップリング１０２、３つのトランス１１２、トランスホルダ１２２、アーム１３２およびスリップリングホルダ１４２が設けられている。これらの部材の動作は、第１回転体５０ａの側の対応する各部材の動作と同じである。   Similarly to the first rotating body 50a side, the second slip ring 102, the three transformers 112, the transformer holder 122, the arm 132, and the slip ring holder 142 are provided on the second rotating body 50b side. . The operations of these members are the same as the operations of the corresponding members on the first rotating body 50a side.

（４）製袋包装機の動作
最初に、製袋包装機１が被包装物Ｃを袋Ｂに充填する動作について説明する。フィルム供給ユニット４から成形機構１３に供給されたフィルムＦは、チューブ１３ａに巻き付けられて筒状に成形され、プルダウンベルト機構１４によって下方に搬送される。チューブ１３ａに巻き付けられたフィルムＦは、上下方向に延びている両端部が重ね合わせられている。筒状に成形されたフィルムＦの重なり部分は、縦シール機構１５によって縦方向にシールされ、筒状フィルムＦｃが形成される。 (4) Operation of the bag making and packaging machine First, the operation of the bag making and packaging machine 1 filling the bag B with the article C to be packaged will be described. The film F supplied from the film supply unit 4 to the forming mechanism 13 is wound around the tube 13 a to be formed into a cylindrical shape, and is conveyed downward by the pull-down belt mechanism 14. The film F wound around the tube 13a is overlapped at both ends extending in the vertical direction. The overlapping portion of the film F formed into a cylindrical shape is sealed in the vertical direction by the vertical sealing mechanism 15 to form a cylindrical film Fc.

縦シールされた筒状フィルムＦｃは、チューブ１３ａから抜けて、横シール機構１７まで搬送される。筒状フィルムＦｃの搬送と同時に、組合せ計量ユニット２で計量された被包装物Ｃがチューブ１３ａの上側の開口に投下される。被包装物Ｃは、チューブ１３ａ内を落下して、チューブ１３ａの下側の開口から排出される。このとき、チューブ１３ａの下方では、筒状フィルムＦｃは、第１ホーン５１ａおよび第１アンビル５１ｂによって既に横シールされた部分を有している。この横シールされた部分より上方の筒状フィルムＦｃは、下端部のみがシールされている袋Ｂを構成している。被包装物Ｃは、この袋Ｂの中に投入される。次に、第１ホーン５１ａおよび第１アンビル５１ｂが、袋Ｂの上端部に相当する部分を横シールして、被包装物Ｃが封入された袋Ｂを形成する。このとき、袋Ｂは、後続する筒状フィルムＦｃと連結されている。被包装物Ｃが封入された袋Ｂは、後続する筒状フィルムＦｃから、切断機構によって切り離される。   The longitudinally sealed tubular film Fc is removed from the tube 13 a and conveyed to the lateral sealing mechanism 17. Simultaneously with the conveyance of the tubular film Fc, the article to be packaged C weighed by the combination weighing unit 2 is dropped into the upper opening of the tube 13a. The packaged article C drops in the tube 13a and is discharged from the lower opening of the tube 13a. At this time, below the tube 13a, the tubular film Fc has a portion that has already been laterally sealed by the first horn 51a and the first anvil 51b. The tubular film Fc above the laterally sealed portion constitutes a bag B in which only the lower end is sealed. The packaged item C is put into the bag B. Next, the first horn 51a and the first anvil 51b laterally seal the portion corresponding to the upper end portion of the bag B to form the bag B in which the article to be packaged C is enclosed. At this time, the bag B is connected to the subsequent cylindrical film Fc. The bag B in which the article to be packaged C is enclosed is separated from the subsequent cylindrical film Fc by a cutting mechanism.

切断機構は、図６に示されるように、第１アンビル５１ｂおよび第２アンビル５２ａの先端部に設けられたカッター７８と、第１ホーン５１ａおよび第２ホーン５２ｂに設けられたスライド溝７９とから構成される。カッター７８は、筒状フィルムＦｃを横シールするタイミングに合わせて、エアシリンダ等の駆動機構によってスライド溝７９に向かって前進する。そして、横シールされた部分の上下方向の中央部にカッター７８が押し当てられて、横シールされた部分が切断される。 As shown in FIG. 6, the cutting mechanism includes a cutter 78 provided at the tip of the first anvil 51b and the second anvil 52a, and a slide groove 79 provided in the first horn 51a and the second horn 52b. Composed. The cutter 78 moves forward toward the slide groove 79 by a driving mechanism such as an air cylinder in accordance with the timing of laterally sealing the cylindrical film Fc. Then, the cutter 78 is pressed against the central portion in the vertical direction of the laterally sealed portion, and the laterally sealed portion is cut.

以上のようにして、被包装物Ｃが封入された袋Ｂが、連続的に製造される。製造された袋Ｂは、その後、ベルトコンベア（図示せず）によって導かれ、厚みチェッカーおよび重さチェッカー等の後工程の装置に移送される。   As described above, the bag B in which the article to be packaged C is enclosed is continuously manufactured. The manufactured bag B is then guided by a belt conveyor (not shown) and transferred to a subsequent device such as a thickness checker and a weight checker.

本実施形態では、第１ホーン５１ａおよび第１アンビル５１ｂは、旋回しながら互いに近付いて筒状フィルムＦｃを挟み込む。そして、第１ホーン５１ａおよび第１アンビル５１ｂは、筒状フィルムＦｃを挟んだまま旋回方向に沿って直線的に移動し、その間に筒状フィルムＦｃを横シールする。その後、第１ホーン５１ａおよび第１アンビル５１ｂは、互いに離間する方向に旋回する。具体的には、図４に示されるように、第１ホーン５１ａおよび第１アンビル５１ｂは、筒状フィルムＦｃを挟み始める時点で旋回運動から直線運動に移行し、筒状フィルムＦｃから離れ始める時点で直線運動から旋回運動に移行する、いわゆるＤモーションを行う。以上の動作は、第２ホーン５２ｂおよび第２アンビル５２ａにも適用可能である。   In the present embodiment, the first horn 51a and the first anvil 51b approach each other while turning and sandwich the tubular film Fc. Then, the first horn 51a and the first anvil 51b move linearly along the turning direction while sandwiching the tubular film Fc, and horizontally seal the tubular film Fc therebetween. Thereafter, the first horn 51a and the first anvil 51b are turned in directions away from each other. Specifically, as shown in FIG. 4, when the first horn 51a and the first anvil 51b start to sandwich the tubular film Fc, the turning movement is changed to the linear movement, and the first horn 51a and the first anvil 51b start to move away from the tubular film Fc. The so-called D-motion is performed in which the movement from the linear motion to the turning motion is performed. The above operation can also be applied to the second horn 52b and the second anvil 52a.

また、本実施形態では、第１ホーン５１ａは、軸受によって、その一端がレバー９１ｄの先端に、その他端がレバー９１ｅの先端に振れ自在に支持されている。第２アンビル５２ａは、軸受によって、その一端がレバー９２ｄの先端に、その他端がレバー９２ｅの先端に振れ自在に支持されている。第１アンビル５１ｂは、軸受によって、その一端がレバー９１ｆの先端に、その他端がレバー９１ｇの先端に振れ自在に支持されている。第２ホーン５２ｂは、軸受によって、その一端がレバー９２ｆの先端に、その他端がレバー９２ｇの先端に振れ自在に支持されている。これにより、第１ホーン５１ａおよび第１アンビル５１ｂのシール面を平面で構成し、かつ、第２ホーン５２ｂおよび第２アンビル５２ａのシール面を平面で構成することができる。   In the present embodiment, the first horn 51a is supported by a bearing such that one end of the first horn 51a swings freely on the tip of the lever 91d and the other end on the tip of the lever 91e. The second anvil 52a is supported by a bearing such that one end of the second anvil 52a is swingable to the tip of the lever 92d and the other end is swingable to the tip of the lever 92e. The first anvil 51b is supported by a bearing such that one end of the first anvil 51b swings freely on the tip of the lever 91f and the other end on the tip of the lever 91g. The second horn 52b is supported by a bearing such that one end of the second horn 52b swings freely on the tip of the lever 92f and the other end on the tip of the lever 92g. Thereby, the sealing surface of the 1st horn 51a and the 1st anvil 51b can be comprised by a plane, and the sealing surface of the 2nd horn 52b and the 2nd anvil 52a can be comprised by a plane.

（５）製袋包装機の特徴
本実施形態に係る製袋包装機１では、ホーン支持体７１は、第１ホーン５１ａから延びる４つの共振体５１３に連結されている第１支持部材７３と、筒状フィルムＦｃの横シール時に加圧部７２によって力が加えられる第２支持部材７４とを有している。第１支持部材７３は、第２支持部材７４と、連結部材７５を介して連結されている。 (5) Characteristics of the bag making and packaging machine In the bag making and packaging machine 1 according to the present embodiment, the horn support 71 is connected to the four resonators 513 extending from the first horn 51a, and the first support member 73. And a second support member 74 to which a force is applied by the pressurizing unit 72 when the cylindrical film Fc is laterally sealed. The first support member 73 is connected to the second support member 74 via a connecting member 75.

筒状フィルムＦｃの横シール時において、加圧部７２は、第１ホーン５１ａを第１アンビル５１ｂに向かって押す。このとき、第２支持部材７４の両端部は、加圧部７２から直接力を受ける。一方、第１支持部材７３は、加圧部７２から直接力を受けない。そのため、筒状フィルムＦｃの横シール時において加圧部７２がホーン支持体７１を加圧しても、第１支持部材７３は撓みにくい。   When the cylindrical film Fc is laterally sealed, the pressurizing unit 72 pushes the first horn 51a toward the first anvil 51b. At this time, both end portions of the second support member 74 directly receive a force from the pressurizing unit 72. On the other hand, the first support member 73 does not receive a direct force from the pressure unit 72. Therefore, even when the pressurizing unit 72 pressurizes the horn support 71 during the horizontal sealing of the tubular film Fc, the first support member 73 is not easily bent.

次に、その理由を具体的に説明する。加圧部７２から直接力を受けている第２支持部材７４は、連結部材７５を介して第１支持部材７３に力を伝えることができる。連結部材７５は、第１支持部材７３の第１中央部７３ａと、第２支持部材７４の第２中央部７４ａとを連結している。そのため、第１支持部材７３の両端部、すなわち、一対の端部固定部７３ｂの近傍は、第２支持部材７４から直接力を受けず、第１支持部材７３の第１中央部７３ａのみが、連結部材７５を介して第２支持部材７４から直接力を受ける。これにより、筒状フィルムＦｃの横シール時において、第１支持部材７３の両端部が直接力を受けることがないので、第１支持部材７３は撓みにくい。また、第２支持部材７４が加圧によって撓んでいる場合においても、第１支持部材７３は、連結部材７５のみを介して第２支持部材７４から力を受けるので、第１支持部材７３は撓みにくい。そして、筒状フィルムＦｃの横シール時において第１支持部材７３は撓みにくいので、第１支持部材７３から４つの共振体５１３を介して力が加えられる第１ホーン５１ａも撓みにくい。   Next, the reason will be specifically described. The second support member 74 receiving the force directly from the pressure unit 72 can transmit the force to the first support member 73 via the connecting member 75. The connecting member 75 connects the first center portion 73 a of the first support member 73 and the second center portion 74 a of the second support member 74. Therefore, both ends of the first support member 73, that is, the vicinity of the pair of end fixing portions 73 b do not receive direct force from the second support member 74, and only the first central portion 73 a of the first support member 73 is A force is directly received from the second support member 74 via the connecting member 75. Thereby, since the both ends of the 1st support member 73 do not receive direct force at the time of the horizontal seal of the cylindrical film Fc, the 1st support member 73 is hard to bend. Even when the second support member 74 is bent by pressure, the first support member 73 receives a force from the second support member 74 only through the connecting member 75, so the first support member 73 is bent. Hateful. Since the first support member 73 is not easily bent when the cylindrical film Fc is laterally sealed, the first horn 51a to which force is applied from the first support member 73 via the four resonators 513 is also not easily bent.

従って、本実施形態に係る製袋包装機１は、筒状フィルムＦｃの横シール時において、第１ホーン５１ａの両端部が第１アンビル５１ｂと接触することを回避することができる。これにより、製袋包装機１は、第１ホーン５１ａおよび第１アンビル５１ｂの破損を防止することができ、第１ホーン５１ａおよび第１アンビル５１ｂの寿命を向上させることができる。   Therefore, the bag making and packaging machine 1 according to the present embodiment can avoid that both end portions of the first horn 51a come into contact with the first anvil 51b when the cylindrical film Fc is laterally sealed. Thereby, the bag making packaging machine 1 can prevent the damage of the 1st horn 51a and the 1st anvil 51b, and can improve the lifetime of the 1st horn 51a and the 1st anvil 51b.

図１２は、比較例としての、ホーンユニット５１に取り付けられた従来のホーン支持体１７１の概略的な平面図である。図１２において、ホーン支持体１７１以外の構成要素は、図１０と同じである。図１２において、ホーン支持体１７１は、ハッチングされた領域で示されている。ホーン支持体１７１は、主として、本体１７１ａと、４つの支持部１７１ｂとから構成される。ホーンユニット５１の４つの共振体５１３は、それぞれ、４つの支持部１７１ｂに固定されている。すなわち、ホーン支持体１７１は、４つの支持部１７１ｂ、および、４つの共振体５１３を介して、第１ホーン５１ａと連結されている。   FIG. 12 is a schematic plan view of a conventional horn support 171 attached to the horn unit 51 as a comparative example. In FIG. 12, the components other than the horn support 171 are the same as those in FIG. In FIG. 12, the horn support 171 is shown in the hatched area. The horn support 171 mainly includes a main body 171a and four support portions 171b. The four resonators 513 of the horn unit 51 are respectively fixed to the four support portions 171b. That is, the horn support 171 is connected to the first horn 51a via the four support portions 171b and the four resonators 513.

図１２に示される比較例では、筒状フィルムＦｃの横シール時において、ホーン支持体１７１の本体１７１ａの両端部は、加圧部７２から直接力を受ける。本体１７１ａの両端部が力を受けることで、第１ホーン５１ａは、第１アンビル５１ｂに向かって押される。しかし、ホーン支持体１７１の本体１７１ａは、その長手方向の両端部において、長手方向に直交する方向の力を受けるので、撓みやすい。図１２では、本体１７１ａは、第１ホーン５１ａに向かって凹となるように撓みやすい。そのため、４つの支持部１７１ｂ、および、４つの共振体５１３を介してホーン支持体１７１の本体１７１ａと連結されている第１ホーン５１ａも、筒状フィルムＦｃの横シール時において、本体１７１ａと同様に撓みやすい。従って、図１２に示されるホーン支持体１７１を用いる場合、筒状フィルムＦｃの横シール時において、第１ホーン５１ａの撓みによって、第１ホーン５１ａの両端部が第１アンビル５１ｂと接触して、第１ホーン５１ａおよび第１アンビル５１ｂが破損するおそれがある。   In the comparative example shown in FIG. 12, both ends of the main body 171 a of the horn support 171 receive a force directly from the pressurizing unit 72 when the cylindrical film Fc is laterally sealed. The first horn 51a is pushed toward the first anvil 51b by receiving both ends of the main body 171a. However, since the main body 171a of the horn support 171 receives a force in a direction orthogonal to the longitudinal direction at both ends in the longitudinal direction, the body 171a is easily bent. In FIG. 12, the main body 171a is easily bent so as to be concave toward the first horn 51a. Therefore, the first horn 51a connected to the main body 171a of the horn support 171 via the four support portions 171b and the four resonators 513 is also the same as the main body 171a when the cylindrical film Fc is laterally sealed. It is easy to bend. Accordingly, when the horn support 171 shown in FIG. 12 is used, both ends of the first horn 51a come into contact with the first anvil 51b due to the bending of the first horn 51a when the cylindrical film Fc is laterally sealed. The first horn 51a and the first anvil 51b may be damaged.

（６）変形例
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。 (6) Modifications One embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

（６−１）変形例Ａ
本実施形態では、第１支持部材７３の第１中央部７３ａは、左右方向の両端の共振体５１３が固定される一対の端部固定部７３ｂの間に位置している。しかし、第１支持部材７３の第１中央部７３ａは、第１ホーン５１ａおよび第１アンビル５１ｂに挟まれている筒状フィルムＦｃの両端の間に位置してもよい。 (6-1) Modification A
In this embodiment, the 1st center part 73a of the 1st support member 73 is located between a pair of edge part fixing | fixed part 73b to which the resonator 513 of the both ends of the left-right direction is fixed. However, the first central portion 73a of the first support member 73 may be positioned between both ends of the tubular film Fc sandwiched between the first horn 51a and the first anvil 51b.

図１３は、本変形例における、ホーンユニット５１に取り付けられたホーン支持体７１の概略的な平面図である。図１３において、ホーン支持体７１の連結部材７５以外の構成要素は、図１０と同じである。図１３において、ホーン支持体７１は、ハッチングされた領域で示されている。本変形例では、ホーン支持体７１の連結部材７５の左右方向の幅Ｗ１は、筒状フィルムＦｃの左右方向の幅Ｗ２よりも小さい。   FIG. 13 is a schematic plan view of the horn support 71 attached to the horn unit 51 in the present modification. In FIG. 13, components other than the connecting member 75 of the horn support 71 are the same as those in FIG. In FIG. 13, the horn support 71 is shown in a hatched area. In this modification, the lateral width W1 of the connecting member 75 of the horn support 71 is smaller than the lateral width W2 of the tubular film Fc.

本変形例では、本実施形態と同様に、第２支持部材７４の両端部は、加圧部７２から直接力を受けるが、第１支持部材７３は、加圧部７２から直接力を受けない。そのため、筒状フィルムＦｃの横シール時において加圧部７２がホーン支持体７１を加圧しても、第１支持部材７３は撓みにくい。   In the present modification, as in the present embodiment, both ends of the second support member 74 receive a direct force from the pressurizing unit 72, but the first support member 73 does not receive a direct force from the pressurizing unit 72. . Therefore, even when the pressurizing unit 72 pressurizes the horn support 71 during the horizontal sealing of the tubular film Fc, the first support member 73 is not easily bent.

（６−２）変形例Ｂ
本実施形態では、第１支持部材７３の第１中央部７３ａは、左右方向の両端の共振体５１３が固定される一対の端部固定部７３ｂの間に位置している。しかし、第１支持部材７３の第１中央部７３ａは、左右方向の中央に位置する一対の共振体５１３が固定される、一対の中央固定部７３ｃの間に位置してもよい。 (6-2) Modification B
In this embodiment, the 1st center part 73a of the 1st support member 73 is located between a pair of edge part fixing | fixed part 73b to which the resonator 513 of the both ends of the left-right direction is fixed. However, the first center portion 73a of the first support member 73 may be positioned between the pair of center fixing portions 73c to which the pair of resonators 513 positioned at the center in the left-right direction are fixed.

図１４は、本変形例における、ホーンユニット５１に取り付けられたホーン支持体７１の概略的な平面図である。図１４において、ホーン支持体７１の連結部材７５以外の構成要素は、図１０と同じである。図１４において、ホーン支持体７１は、ハッチングされた領域で示されている。本変形例では、第１支持部材７３の第１中央部７３ａは、第１支持部材７３の一対の中央固定部７３ｃの間の部分である。一対の中央固定部７３ｃは、ホーンユニット５１の４つの共振体５１３の内、左右方向の両端の共振体５１３を除く２つの共振体５１３がそれぞれ固定される部分である。第１中央部７３ａは、連結部材７５が連結される部分である。そのため、図１４に示されるように、連結部材７５の左右方向の幅Ｗ１は、一対の中央固定部７３ｃに固定される２つの共振体５１３の間の間隔Ｗ３よりも小さい。   FIG. 14 is a schematic plan view of a horn support 71 attached to the horn unit 51 in the present modification. 14, components other than the connecting member 75 of the horn support 71 are the same as those in FIG. In FIG. 14, the horn support 71 is shown in a hatched area. In the present modification, the first center portion 73 a of the first support member 73 is a portion between the pair of center fixing portions 73 c of the first support member 73. The pair of central fixing portions 73 c are portions to which two resonators 513 except for the resonators 513 at both ends in the left-right direction are fixed, among the four resonators 513 of the horn unit 51. The first central portion 73a is a portion to which the connecting member 75 is connected. Therefore, as shown in FIG. 14, the width W1 of the connecting member 75 in the left-right direction is smaller than the interval W3 between the two resonators 513 fixed to the pair of central fixing portions 73c.

本変形例では、本実施形態と同様に、第２支持部材７４の両端部は、加圧部７２から直接力を受けるが、第１支持部材７３は、加圧部７２から直接力を受けない。そのため、筒状フィルムＦｃの横シール時において加圧部７２がホーン支持体７１を加圧しても、第１支持部材７３は撓みにくい。   In the present modification, as in the present embodiment, both ends of the second support member 74 receive a direct force from the pressurizing unit 72, but the first support member 73 does not receive a direct force from the pressurizing unit 72. . Therefore, even when the pressurizing unit 72 pressurizes the horn support 71 during the horizontal sealing of the tubular film Fc, the first support member 73 is not easily bent.
