　従来、単一の包装用フィルムロールをカットして複数に分割し、分割された各フィルムに対して搬送方向に沿って縦シールをして複数の筒状フィルムを生成し、各筒状フィルムに被包装物を充填した後、搬送方向に垂直な方向に単一の横シール機構により横シールを行い、同時に横シール機構に設けられたカッターで各筒状フィルムを切断する製袋包装装置が知られている。例えば、特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置には、単一の包装用フィルムロールをカットして５つに分割し、分割された各フィルムに対して搬送方向に沿って縦シールをして複数の筒状フィルムを生成し、単一の横シール機構を用いて、筒状フィルムの横シールおよび、カッターによる切断を行う構成が開示されている。複数の製袋ラインで包装用フィルムロールや横シール機構を共用することで、製袋包装装置をコンパクトにでき、製袋包装装置のコストダウンを図ることができるというメリットがある。 Conventionally, a single film roll for packaging is cut and divided into a plurality of pieces, and a plurality of tubular films are produced by vertically sealing each divided film along the conveying direction. A bag making and packaging device is known in which after a package is filled, horizontal sealing is performed by a single horizontal sealing mechanism in a direction perpendicular to the conveying direction, and at the same time, each cylindrical film is cut by a cutter provided in the horizontal sealing mechanism. It has been. For example, in the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327), a single packaging film roll is cut and divided into five parts, which are conveyed to the divided films. A configuration is disclosed in which a plurality of cylindrical films are generated by performing vertical sealing along a direction, and the horizontal sealing of the cylindrical film and cutting with a cutter are performed using a single horizontal sealing mechanism. By sharing a packaging film roll and a horizontal sealing mechanism in a plurality of bag making lines, there is an advantage that the bag making and packaging apparatus can be made compact and the cost of the bag making and packaging apparatus can be reduced.
　なお、一般に、製袋包装装置は、被計量物の計量を高速かつ高精度に行うことが可能な組合せ計量器を有する製袋包装装置と共に使用されることが多い。組合せ計量器は、複数のホッパに一時的に収容される被計量物を計量し、計量結果を用いて組合せ演算を行い、演算値が所定の許容範囲内となるホッパの組合せを選択し、選択された組合せに含まれるホッパ内の被計量物を集合させ、集合させられた被計量物を被包装物として製袋包装装置に供給する。 In general, the bag making and packaging apparatus is often used together with a bag making and packaging apparatus having a combination weighing device capable of measuring an object to be weighed at high speed and with high accuracy. The combination weigher measures the objects to be temporarily stored in multiple hoppers, performs combination calculation using the measurement results, and selects and selects the combination of hoppers whose calculated value is within the predetermined allowable range. The objects to be weighed in the hopper included in the combination are assembled, and the assembled objects to be weighed are supplied to the bag making and packaging apparatus as the objects to be packaged.
　ところで、組合せ計量器においては、いずれのホッパの組合せを選択しても、被計量物の計量値の合計が許容範囲に収まらない、いわゆる組合せエラーが発生する場合がある。特に、組合せエラーの中には、ホッパに収容される被計量物を、許容範囲を超えて排出しなければ組合せエラーを解消できない場合がある。例えば、最軽量の被計量物の組合せであっても、その計量値の合計が許容範囲を超過する場合である。 By the way, in a combination weighing instrument, there is a case where a so-called combination error occurs in which the total of measured values of the objects to be weighed does not fall within the allowable range regardless of which hopper combination is selected. In particular, among the combination errors, there is a case where the combination error cannot be resolved unless the objects to be weighed accommodated in the hopper are discharged beyond an allowable range. For example, even in the lightest combination of objects to be weighed, the sum of the measured values exceeds the allowable range.
　組合せ計量器から、特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置の一部の製袋ラインに、許容範囲を超過した被計量物が被包装物として排出される場合、供給された被包装物が１袋に収容可能な量を超過し、横シール部で被包装物の噛み込みが発生する場合がある。この場合、その過剰量の被包装物が供給された製袋ラインにおいて被包装物の噛み込みを原因とした、横シール不良が発生する。さらに、特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置では、横シール機構を共用するため、一部の製袋ラインにおける被包装物の噛み込みに由来して、他の製袋ラインにおいても、シール不良が発生し得る。そのため、被包装物が適正に供給された製袋ラインにおいてもシール不良品が発生し、適正に供給された被包装物のロスが生じる。 When a weighed item exceeding the allowable range is discharged as a packaged item from the combination weighing device to a part of the bag making line of the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327) In some cases, the supplied packaging material exceeds the amount that can be accommodated in one bag, and the lateral packaging portion bites the packaging material. In this case, a lateral seal failure occurs due to the biting of the package in the bag making line to which the excessive package is supplied. Furthermore, since the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327) shares a horizontal seal mechanism, it is derived from the biting of an article to be packaged in some bag making lines. Also in the bag making line, a sealing failure may occur. For this reason, a defective product is generated even in a bag-making line in which the articles to be packaged are properly supplied, and loss of the articles to be packaged properly is generated.
　このような問題は、横シール機構を製袋ライン毎に設ければ解決可能であるが、その場合には、横シール機構を共用することにより得られるメリットが失われる。 Such a problem can be solved by providing a horizontal seal mechanism for each bag making line, but in that case, the merit obtained by sharing the horizontal seal mechanism is lost.
　本発明の課題は、複数の製袋ラインを有し、横シール機構を共用する製袋包装装置において、一部の製袋ラインでシール不良が発生した場合であっても、そのことを原因として、その他の製袋ラインでシール不良が起こることがない製袋包装装置を提供することにある。 The problem of the present invention is that, in a bag making and packaging apparatus having a plurality of bag making lines and sharing a horizontal sealing mechanism, even if a seal failure occurs in some bag making lines, Another object of the present invention is to provide a bag making and packaging apparatus that does not cause defective sealing in other bag making lines.
　本発明に係る製袋包装装置は、筒状フィルムを横シールして袋を形成する第１から第ｎの製袋ラインを有する（ｎは２以上の整数）製袋包装装置であって、横シール機構を備える。横シール機構は、筒状フィルムを挟み込んで熱圧着し横シールを行う一対のシールジョーを有し、第１から第ｎの製袋ラインで共用される。少なくとも一方のシールジョーは、第１から第ｎの製袋ラインの筒状フィルムを個別に挟み込むｎ個の分割部材に分割されている。 A bag making and packaging apparatus according to the present invention is a bag making and packaging apparatus having first to n-th bag making lines (n is an integer of 2 or more) for horizontally sealing a tubular film to form a bag. A sealing mechanism is provided. The horizontal sealing mechanism has a pair of sealing jaws that sandwich and seal a tubular film to perform horizontal sealing, and is shared by the first to nth bag making lines. At least one of the sealing jaws is divided into n divided members that individually sandwich the tubular films of the first to nth bag making lines.
　これにより、横シール機構は共有でありながら、製袋ライン別に横シールをすることが可能になる。製袋ライン別に横シール可能であるため、例えば被包装物の供給量過剰により、１の製袋ラインのシールジョー部分で被包装物の噛み込みが発生した場合にも、他の製袋ラインにおいては、そのことを原因としたシール不良が発生しにくい。その結果、不良包装の発生率が低減される。 This makes it possible to carry out horizontal sealing for each bag making line while sharing the horizontal sealing mechanism. Since it is possible to perform horizontal sealing for each bag making line, for example, even if the biting of the packaged object occurs in the sealing jaw part of one bag making line due to an excessive supply of packaged goods, Is less likely to cause a seal failure due to that. As a result, the incidence of defective packaging is reduced.
　また、本発明に係る製袋包装装置では、横シール機構は、ｎ個の分割部材を支持するベース部材をさらに有することが望ましい。ベース部材は、ｎ個の分割部材に共用されることが望ましい。 Further, in the bag making and packaging apparatus according to the present invention, it is desirable that the lateral seal mechanism further includes a base member that supports n divided members. It is desirable that the base member is shared by n divided members.
　これにより、横シール機構を駆動する駆動部を製袋包装装置全体で共用でき、製袋包装装置のコストダウンを図りながら、シール不良包装の発生率を低減できる。 This allows the drive unit that drives the lateral seal mechanism to be shared by the entire bag making and packaging apparatus, and reduces the rate of defective seal packaging while reducing the cost of the bag making and packaging apparatus.
　また、本発明に係る製袋包装装置では、横シール機構は、分割部材とベース部材とを連結する伸縮部材をさらに備えることが望ましい。 Moreover, in the bag making and packaging apparatus according to the present invention, it is desirable that the lateral seal mechanism further includes an elastic member that connects the divided member and the base member.
　これにより、一部の分割部材に大きな力が加わった場合には、その分割部材がベース部材方向に回避するように移動可能である。したがって、一部の製袋ラインにおいて、横シール機構部での被包装物の噛み込みが発生しても、他の製袋ラインのシールジョーの動作には影響を及ぼさない。その結果、シール不良品の発生率を低減できる。 Thus, when a large force is applied to some of the divided members, the divided members can move so as to avoid the base member direction. Therefore, in some bag making lines, even if the laterally packed mechanism bites into the package, it does not affect the operation of the seal jaws in other bag making lines. As a result, the incidence of defective seals can be reduced.
　また、本発明に係る製袋包装装置では、横シールによって形成された袋を後続の筒状フィルムから切り離すカッター部をさらに有することが望ましい。カッター部は、第１から第ｎの製袋ラインの筒状フィルムを個別に切り離すｎ個の分割刃物を有することが望ましい。 Moreover, in the bag making and packaging apparatus according to the present invention, it is desirable to further include a cutter unit that separates the bag formed by the transverse seal from the subsequent cylindrical film. It is desirable that the cutter unit has n divided blades for individually cutting the cylindrical films of the first to nth bag making lines.
　特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置では、共用されている横シール機構にカッターが具備されているため、一部の製袋ラインだけの筒状フィルムを切断することができない。そのため、一部の製袋ラインに過剰量の被包装物が供給された場合に、以下のような問題が発生する。 In the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327), since the cutter is provided in the shared horizontal seal mechanism, a cylindrical film of only a part of the bag making line is cut. Can not do it. Therefore, the following problems occur when an excessive amount of articles to be packaged is supplied to some bag-making lines.
　一部の製袋ラインに過剰量の被包装物が供給されシール不良が発生している場合には、筒状フィルムを切断すると、被包装物が外部に漏れ出る可能性がある。そのため筒状フィルムは切断されない方がよい。一方で、適正量の被包装物が供給され、横シールに不良がない製袋ラインにおいては、不良品率を抑制するため、その筒状フィルムを切り離し、切り離した袋を製品として利用することが望ましい。 ¡If an excessive amount of packaged material is supplied to some bag-making lines and a sealing failure occurs, the packaged product may leak outside when the tubular film is cut. Therefore, it is better that the tubular film is not cut. On the other hand, in a bag making line in which an appropriate amount of articles to be packaged is supplied and there is no defect in the lateral seal, in order to suppress the defective product rate, the cylindrical film is cut off and the cut bag can be used as a product. desirable.
　これに対し、本発明に係る製袋包装装置では、カッター部は、製袋ラインの筒状フィルムを個別に切り離す分割刃物を有するため、横シール機構を共用しながら、製袋ライン別に独立した製袋が可能となる。例えば、一部の製袋ラインで、連包状態（２袋分の筒状フィルムが、横シールされず連なった状態）で製袋をすることが必要になった場合にも、他の製袋ラインにおいては１袋ずつ筒状フィルムとの切り離しが可能である。その結果、不良包装の発生率を抑制しながら、装置の稼働率を上げることが可能である。 On the other hand, in the bag making and packaging apparatus according to the present invention, the cutter unit has a split blade that individually cuts the tubular film of the bag making line, so that the horizontal seal mechanism is shared, and independent manufacturing is performed for each bag making line. Bags are possible. For example, when it is necessary to make a bag in some bag making lines in a continuous packaging state (a state where two bags of cylindrical films are connected without being horizontally sealed), The line can be separated from the tubular film one bag at a time. As a result, it is possible to increase the operating rate of the apparatus while suppressing the occurrence rate of defective packaging.
　つまり、本発明に係る製袋包装装置では、製袋ライン毎に筒状フィルムから袋を切り離すことが可能であるため、製袋包装装置の稼働率を向上させることができる。複数の製袋ラインを有し、筒状フィルムに横シールした後、カッターで袋と筒状フィルムとを切り離す製袋包装装置であるため、シール不良品は排除しつつ、稼働率を向上させた製袋包装装置を提供することができる。 That is, in the bag making and packaging apparatus according to the present invention, since the bag can be separated from the tubular film for each bag making line, the operating rate of the bag making and packaging apparatus can be improved. Since it is a bag making and packaging device that has a plurality of bag making lines and laterally seals on a tubular film, the bag and the tubular film are separated with a cutter, thus improving the operating rate while eliminating defective seals. A bag making and packaging apparatus can be provided.
　また、本発明に係る製袋包装装置は、シート状のフィルムを筒状に成形するフォーマを具備する製袋ラインを少なくとも２つ有し、製袋ラインでフィルムロールを共用する製袋包装装置であり、切断部と、バッファ部とを備えることが望ましい。切断部は、フィルムロールから連続的に引き出される単一のシート状のフィルムを各製袋ライン用に切り離すことが望ましい。バッファ部は、切断部と製袋ラインがそれぞれに有するフォーマとの間に配置され、フィルムを一時的に製袋ライン別に溜めることが望ましい。 Moreover, the bag making packaging apparatus which concerns on this invention is a bag making packaging apparatus which has at least two bag making lines which comprise the former which shape | molds a sheet-like film in a cylinder shape, and shares a film roll in a bag making line. It is desirable to include a cutting unit and a buffer unit. As for a cutting part, it is desirable to cut | disconnect the single sheet-like film continuously pulled out from a film roll for each bag making line. It is desirable that the buffer unit is disposed between the cutting unit and the formers included in each of the bag making lines, and temporarily stores the film for each bag making line.
　特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置では、単一の包装用フィルムロールから分割された分割フィルムが一様に製袋ラインに送られるため、製袋ライン毎にフィルムの搬送量を変更することはできない。 In the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327), the divided films divided from a single packaging film roll are uniformly fed to the bag making line. However, the amount of film transport cannot be changed.
　その結果、何らかの原因で、一部の製袋ラインに被包装物が供給されない場合でも、全ての製袋ラインを一律に稼働させる必要があり、被包装物が供給されない製袋ラインではフィルムロスが発生するという問題がある。このような問題は、製袋ライン毎に包装用ロールを設ければ解決可能であるが、その場合には、包装用ロールを共用することにより得られるメリットが失われる。 As a result, even if the packaging materials are not supplied to some bag making lines for some reason, it is necessary to operate all the bag making lines uniformly, and there is a film loss in the bag making lines where the packaging materials are not supplied. There is a problem that occurs. Such a problem can be solved by providing a packaging roll for each bag making line, but in that case, the merit obtained by sharing the packaging roll is lost.
　これに対し、本発明に係る製袋包装装置は、複数の製袋ラインで単一の包装用フィルムロールを共用しながら、製袋ライン別にフィルムの送り量を制御することができる。一部の製袋ラインのフィルムだけを搬送して、他の製袋ラインのフィルム搬送を停止するという操作も可能になるため、フィルムロスの発生が抑制されやすい。 On the other hand, the bag making and packaging apparatus according to the present invention can control the film feed amount for each bag making line while sharing a single packaging film roll in a plurality of bag making lines. Since it becomes possible to carry out an operation of conveying only the film of some bag-making lines and stopping the film conveyance of other bag-making lines, it is easy to suppress the occurrence of film loss.
　また、本発明に係る製袋包装装置は、バッファ部に溜められているフィルムの量を把握するバッファ量把握部をさらに備えることが望ましい。 Moreover, it is desirable that the bag making and packaging apparatus according to the present invention further includes a buffer amount grasping unit that grasps the amount of film accumulated in the buffer unit.
　これにより、各製袋ラインの特性等の違いを原因として、各製袋ラインのフィルム送り量が一時的に異なる場合であっても、バッファ部に溜められているフィルム量を把握することでフィルム送り量の差が明確になり、フィルム送り量の補正を行うことが容易になる。 By this, even if the film feed amount of each bag making line is temporarily different due to the difference in the characteristics of each bag making line, etc., the film can be obtained by grasping the amount of film stored in the buffer section. The difference in the feed amount becomes clear and it becomes easy to correct the film feed amount.
　また、本発明に係る製袋包装装置では、縦シール機構と、横シール機構とを有することが望ましい。縦シール機構は、フォーマにより筒状に形成されたフィルムの縦方向に重なる部分を連続的に縦シールする。横シール機構は、縦シールがされた筒状フィルムを横シールして袋を形成する。バッファ部は、少なくとも袋１つ分のフィルムを溜めることが可能であることが望ましい。 Also, it is desirable that the bag making and packaging apparatus according to the present invention has a vertical seal mechanism and a horizontal seal mechanism. The longitudinal seal mechanism continuously longitudinally seals the overlapping portion in the longitudinal direction of the film formed into a cylindrical shape by the former. The lateral seal mechanism forms a bag by laterally sealing the cylindrical film that has been longitudinally sealed. It is desirable that the buffer unit can store at least one bag of film.
　これにより、被包装物が供給されないなどの原因で一部の製袋ラインを停止する必要がある場合にも、そのサイクルに本来使用されるはずであったフィルムをバッファ部に溜めることができ、フィルムのロスが発生しない。逆に、製袋ラインが動いているにもかかわらず、フィルムロールの搬送を停止すべき状況が発生した場合にも、バッファ部に溜めておいたフィルムを利用することが可能で、製袋包装装置を停止させる必要がない。つまり、フィルムのロスを抑制すると装置の稼働率を上げることができる。 Thereby, even when it is necessary to stop some bag-making lines due to reasons such as not being supplied with packages, it is possible to store the film that was originally used for that cycle in the buffer section, No film loss occurs. Conversely, even when the bag making line is moving, it is possible to use the film stored in the buffer even when there is a situation where film roll transport should be stopped. There is no need to stop the device. That is, if the film loss is suppressed, the operating rate of the apparatus can be increased.
　また、本発明に係る製袋包装装置は、シート状のフィルムを筒状に成形するフォーマを具備する製袋ラインを少なくとも２つ有し、前記製袋ラインでフィルムロールを共用する製袋包装装置であり、切断部を備えることが望ましい。切断部は、フィルムロールから連続的に引き出される単一のシート状のフィルムを各製袋ライン用に切り離すことが望ましい。切断部は、フィルムを切り離す切断ツールとしての第１切断部材および第２切断部材と、第１切断部材と第２切断部材の少なくとも一方が常にフィルムに接触した状態で第１切断部材から第２切断部材に切断ツールを切り替える切替部とを有することが望ましい。 In addition, the bag making and packaging apparatus according to the present invention has at least two bag making lines having a former for forming a sheet-like film into a cylindrical shape, and uses the film roll in the bag making line. It is desirable to provide a cutting part. As for a cutting part, it is desirable to cut | disconnect the single sheet-like film continuously pulled out from a film roll for each bag making line. The cutting unit performs the second cutting from the first cutting member in a state where at least one of the first cutting member and the second cutting member as a cutting tool for cutting the film, and at least one of the first cutting member and the second cutting member is always in contact with the film. It is desirable to have the switching part which switches a cutting tool to a member.
　特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置では、単一の包装用フィルムロールを分割して利用するため、スリッタにより連続的にフィルムを切断している。スリッタは次第に刃先が劣化するため交換が必要であり、特許文献１（実公昭５８－５４３２７号公報）に記載の製袋包装装置では、スリッタ交換のたびに定期的に機械を停止させる必要がある。 In the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327), since a single packaging film roll is divided and used, the film is continuously cut by a slitter. The slitter needs to be replaced because the blade edge gradually deteriorates. In the bag making and packaging apparatus described in Patent Document 1 (Japanese Utility Model Publication No. 58-54327), it is necessary to periodically stop the machine every time the slitter is replaced. .
　ところが、スリッタの交換のために機械を停止させると、製袋包装装置の稼働率が低下するという問題がある。このような問題は、製袋ライン毎に包装用ロールを設ければ解決可能であるが、その場合には、包装用ロールを共用することにより得られるメリットが失われる。 However, when the machine is stopped to replace the slitter, there is a problem that the operating rate of the bag making and packaging apparatus decreases. Such a problem can be solved by providing a packaging roll for each bag making line, but in that case, the merit obtained by sharing the packaging roll is lost.
　これに対し、本発明に係る製袋包装装置では、第１切断部材もしくは第２切断部材が常にフィルムを切断しているため、切断部材の切替の際に製袋包装装置を停止する必要がない。そのため、複数の製袋ラインで単一の包装用フィルムロールを共用する製袋包装装置において、その稼働率を向上させることができる。 On the other hand, in the bag making and packaging apparatus according to the present invention, since the first cutting member or the second cutting member always cuts the film, it is not necessary to stop the bag making and packaging apparatus when switching the cutting member. . Therefore, in a bag making and packaging apparatus that shares a single packaging film roll with a plurality of bag making lines, the operating rate can be improved.
　また、本発明に係る製袋包装装置では、切替部は、自動で第１切断部材から第２切断部材に切断ツールを切り替えることが望ましい。 In the bag making and packaging apparatus according to the present invention, it is desirable that the switching unit automatically switches the cutting tool from the first cutting member to the second cutting member.
　これにより、作業員が手動で切断ツールを切り替える工数を削減することができる。 This can reduce the man-hour for the operator to manually switch the cutting tool.
　また、本発明に係る製袋包装装置では、切断部は、平面視において棒状のサポート部材を有することが望ましい。サポート部材は、平面視においてサポート部材の両端に前記第１切断部材および前記第２切断部材がそれぞれ取り外し可能に固定される第１および第２固定部と、第１固定部と第２固定部との間に配置される軸部とを有する。サポート部材は、軸部を中心としてフィルム面に交差する方向に回動可能である。 Further, in the bag making and packaging apparatus according to the present invention, it is desirable that the cutting portion has a rod-shaped support member in plan view. The support member includes first and second fixing portions, the first fixing portion and the second fixing portion, to which the first cutting member and the second cutting member are detachably fixed to both ends of the support member in plan view, And a shaft portion disposed between the two. The support member is rotatable in a direction intersecting the film surface around the shaft portion.
　これにより、簡易な構成で切断部材を稼働中に切り替え可能な切替部を実現できる。 This makes it possible to realize a switching unit that can switch the cutting member during operation with a simple configuration.
　また、本発明に係る製袋包装装置では、第２切断部材は、第１切断部材がフィルムから離れる時点で、フィルムの切り離しを開始していることが望ましい。 Also, in the bag making and packaging apparatus according to the present invention, it is desirable that the second cutting member starts to separate the film when the first cutting member leaves the film.
　これにより、常にいずれかの切断部材がフィルムを切り離しているため、製袋包装装置の稼働率を高く維持できる。 Thereby, since one of the cutting members always cuts the film, the operation rate of the bag making and packaging apparatus can be maintained high.
　本発明に係る製袋包装装置では、複数の製袋ラインが横シール機構を共用するが、横シール機構が有するシールジョーは各製袋ライン用に分割されている。これにより、製袋ライン別に横シールをすることが可能になる。そのため、例えば被包装物の供給量過剰により、１の製袋ラインのシールジョー部分で被包装物の噛み込みが発生した場合にも、そのことを原因としたシール不良は他の製袋ラインでは発生しにくい。その結果、不良包装の発生率を低減できる。 In the bag making and packaging apparatus according to the present invention, a plurality of bag making lines share the horizontal seal mechanism, but the seal jaws of the horizontal seal mechanism are divided for each bag making line. Thereby, it becomes possible to carry out a horizontal seal for each bag making line. For this reason, for example, even when the package jaws are bitten in the seal jaw part of one bag making line due to an excessive supply amount of the packaged items, the sealing failure caused by that is not possible in other bag making lines. Hard to occur. As a result, the incidence of defective packaging can be reduced.
　また、本発明に係る製袋包装装置では、カッター部が各製袋ライン用に分割されている。製袋ライン毎に筒状フィルムから袋を切り離すことが可能で、シール不良品等の割合は抑制しつつ、装置の稼働率を上げることができる。 Further, in the bag making and packaging apparatus according to the present invention, the cutter portion is divided for each bag making line. The bag can be separated from the tubular film for each bag making line, and the operating rate of the apparatus can be increased while suppressing the ratio of defective seals and the like.
　また、本発明に係る製袋包装装置では、複数の製袋ラインでフィルムロールを共有する製袋包装装置であって、各製袋ラインに分割後のフィルムを一時的に溜めるバッファ部を備える。そのため、製袋ライン別にフィルムの送り量を制御可能である。一部の製袋ラインのフィルムだけ搬送して、他の製袋ラインのフィルム搬送を停止するという操作が可能になるため、フィルムロスの発生が抑制されやすい。 Further, the bag making and packaging apparatus according to the present invention is a bag making and packaging apparatus that shares a film roll among a plurality of bag making lines, and includes a buffer unit for temporarily storing the divided film in each bag making line. Therefore, the film feed amount can be controlled for each bag making line. Since it becomes possible to perform an operation of transporting only the film of some bag making lines and stopping the film transport of other bag making lines, it is easy to suppress the occurrence of film loss.
　また、本発明に係る製袋包装装置では、複数の製袋ラインでフィルムロールを共有する製袋包装装置であって、フィルムロールを切断する第１切断部材もしくは第２切断部材のどちらかが、切断部材の切り替え時にも常にフィルムを切断している。切断部材の切替の際に製袋包装装置を停止する必要がなく、製袋包装装置の稼働率を高めることができる。 Moreover, in the bag making and packaging apparatus according to the present invention, the bag making and packaging apparatus shares a film roll with a plurality of bag making lines, and either the first cutting member or the second cutting member for cutting the film roll is provided. The film is always cut even when the cutting member is switched. It is not necessary to stop the bag making and packaging apparatus when switching the cutting member, and the operating rate of the bag making and packaging apparatus can be increased.

　被包装物Ｃの供給される方の製袋ラインＭ１，Ｍ２のフィルム貯留部４０Ａ，４０Ｂに１袋分のフィルムＦが貯留されている場合には、フィルム繰り出し部８０は休止させ、被包装物Ｃの供給される方のプルダウンベルト１３Ａ，１３Ｂだけを駆動して、フィルム貯留部４０Ａ，４０Ｂから１袋分のフィルムＦを製袋包装部３に供給する。 When one bag of film F is stored in the film storage units 40A and 40B of the bag making lines M1 and M2 to which the product C is supplied, the film feeding unit 80 is paused and the product to be packaged. Only the pull-down belts 13A and 13B to which C is supplied are driven to supply one bag of film F to the bag making and packaging unit 3 from the film storage units 40A and 40B.
　被包装物Ｃの供給される方の製袋ラインＭ１，Ｍ２のフィルム貯留部４０Ａ，４０Ｂに１袋分のフィルムＦが貯留されていない場合には、被包装物Ｃの供給されない方の製袋ラインＭ２，Ｍ１のフィルム貯留部４０Ｂ，４０Ａに１袋分のフィルムＦを貯留できるかがバッファ量把握部５ａにより確認される。１袋分のフィルムＦが貯留可能な場合には、フィルム繰り出し部８０は動かしたままとし、被包装物Ｃの供給されない製袋ラインＭ２，Ｍ１では、プルダウンベルト１３Ｂ，１３Ａは駆動しない。つまり、被包装物Ｃの供給されない製袋ラインＭ２，Ｍ１のフィルム貯留部４０Ｂ，４０Ａでは、フィルムＦが貯留される。一方、被包装物Ｃの供給される方製袋ラインＭ１，Ｍ２では、プルダウンベルト１３Ａ，１３Ｂを駆動して、１袋分のフィルムＦを製袋包装部３に供給する。 When the film F for one bag is not stored in the film storage portions 40A and 40B of the bag making lines M1 and M2 to which the packaged article C is supplied, the one for which the packaged article C is not supplied. The buffer amount grasping unit 5a confirms whether one bag of film F can be stored in the film storage units 40B and 40A of the lines M2 and M1. When the film F for one bag can be stored, the film feeding portion 80 is kept moving, and the pull-down belts 13B and 13A are not driven in the bag making lines M2 and M1 to which the article C is not supplied. That is, the film F is stored in the film storage portions 40B and 40A of the bag making lines M2 and M1 to which the article C is not supplied. On the other hand, in the bag making lines M1 and M2 to which the article C is supplied, the pull-down belts 13A and 13B are driven to supply the film F for one bag to the bag making and packaging unit 3.

　本実施形態に係る製袋包装装置１は、筒状フィルムＦｔを横シールして袋を形成する第１および第２製袋ラインＭ１，Ｍ２を有する製袋包装装置であって、横シール機構２０を備える。横シール機構２０は、筒状フィルムＦｔを挟み込んで熱圧着し横シールを行う一対のシールジョー（後側シールジョー２１および前側シールジョー２２）を有し、第１および第２の製袋ラインＭ１，Ｍ２で共用される。後側シールジョー２１は、第１製袋ラインＭ１の筒状フィルムＦｔを個別に挟み込む第１後側シールジョー２１Ａと、第２製袋ラインＭ２の筒状フィルムＦｔを個別に挟み込む第２後側シールジョー２１Ｂと、に分割されている。 (3) Features (3-1)
The bag making and packaging apparatus 1 according to the present embodiment is a bag making and packaging apparatus having first and second bag making lines M1 and M2 that form a bag by laterally sealing the tubular film Ft, and includes a lateral sealing mechanism 20. Is provided. The lateral seal mechanism 20 has a pair of seal jaws (a rear seal jaw 21 and a front seal jaw 22) that sandwich and seal the tubular film Ft and perform lateral seal, and the first and second bag making lines M1. , M2. The rear seal jaw 21 includes a first rear seal jaw 21A that individually sandwiches the tubular film Ft of the first bag making line M1, and a second rear side that individually sandwiches the tubular film Ft of the second bag making line M2. It is divided into a seal jaw 21B.
　これにより、横シール機構２０は共有でありながら、第１および第２製袋ラインＭ１，Ｍ２で、ライン別に横シールをすることが可能である。そのため、例えば被包装物Ｃの供給量過剰により、一方の製袋ラインＭ１，Ｍ２のシールジョー部分（第１後側シールジョー２１Ａと前側シールジョー２２との間、もしくは、第２後側シールジョー２１Ｂと前側シールジョー２２との間）で被包装物Ｃの噛み込みが発生した場合にも、他方の製袋ラインＭ２，Ｍ１においては、そのことを原因としたシール不良が発生しにくい。その結果、不良包装の発生率が低減される。 Thereby, while the horizontal sealing mechanism 20 is shared, the first and second bag making lines M1 and M2 can perform horizontal sealing for each line. Therefore, for example, due to an excessive supply amount of the article to be packaged C, the sealing jaw portion of one of the bag making lines M1 and M2 (between the first rear sealing jaw 21A and the front sealing jaw 22 or the second rear sealing jaw 21B and the front seal jaw 22), even if the packaged article C is bitten, the other bag making lines M2 and M1 are less likely to cause a sealing failure due to that. As a result, the incidence of defective packaging is reduced.

　本実施形態に係る製袋包装装置１では、横シール機構２０は、第１および第２後側シールジョー２１Ａ，２１Ｂを支持する共用のベース部材２３を有する。 (3-2)
In the bag making and packaging apparatus 1 according to the present embodiment, the lateral seal mechanism 20 has a common base member 23 that supports the first and second rear seal jaws 21A and 21B.
　これにより、横シール機構２０を駆動する駆動部を製袋包装装置１全体で共用でき、製袋包装装置１のコストダウンを図りながら、シール不良包装の発生率を低減できる。 Thus, the drive unit for driving the lateral seal mechanism 20 can be shared by the entire bag making and packaging apparatus 1, and the rate of occurrence of defective packaging can be reduced while reducing the cost of the bag making and packaging apparatus 1.
　（３－３）
　本実施形態に係る製袋包装装置１では、横シール機構２０は、第１および第２後側シールジョー２１Ａ，２１Ｂとベース部材２３とを連結するバネ２４を備える。 (3-3)
In the bag making and packaging apparatus 1 according to the present embodiment, the lateral seal mechanism 20 includes a spring 24 that connects the first and second rear seal jaws 21 </ b> A and 21 </ b> B and the base member 23.
　これにより、一方の後側シールジョー２１Ａ，２１Ｂに大きな力が加わった場合には、その後側シールジョー２１Ａ，２１Ｂがベース部材２３方向に回避するように移動可能である。したがって、一方の製袋ラインＭ１，Ｍ２で、横シール機構２０における被包装物Ｃの噛み込みが発生しても、他方の製袋ラインＭ２，Ｍ１の後側シールジョー２１Ｂ，２１Ａと、前側シールジョー２２による熱圧着には影響を及ぼさない。その結果、シール不良品の発生率を低減できる。 Thus, when a large force is applied to one of the rear seal jaws 21A and 21B, the rear seal jaws 21A and 21B can move so as to avoid the base member 23. Therefore, even if the one of the bag making lines M1 and M2 bites the article C to be packed in the lateral seal mechanism 20, the rear seal jaws 21B and 21A of the other bag making lines M2 and M1 and the front seal The thermocompression bonding by the jaw 22 is not affected. As a result, the incidence of defective seals can be reduced.

　本実施形態に係る製袋包装装置１では、横シールによって形成された袋Ｂを後続の筒状フィルムＦｔから切り離すカッター部３０（カッター部３０Ａ，３０Ｂ）を有する。カッター部３０は、第１および第２製袋ラインＭ１，Ｍ２の筒状フィルムＦｔを個別に切り離す２個の分割刃物を、カッター３２Ａ，３２Ｂとして有する。 (3-4)
The bag making and packaging apparatus 1 according to the present embodiment includes a cutter unit 30 ( cutter units 30A and 30B) that separates the bag B formed by the horizontal seal from the subsequent tubular film Ft. The cutter unit 30 has two divided blades as cutters 32A and 32B that individually cut the tubular films Ft of the first and second bag making lines M1 and M2.
　これにより、横シール機構２０を共用しながら、製袋ラインＭ１，Ｍ２別に独立した製袋が可能となる。例えば、一方の製袋ラインＭ１，Ｍ２で、連包状態（２袋分の筒状フィルムＦｔが横シールされず、連なった状態）で製袋をすることが必要になった場合にも、他の製袋ラインＭ２，Ｍ１においては１袋ずつ筒状フィルムＦｔとの切り離しが可能である。その結果、不良包装の発生率を抑制しながら、製袋包装装置１の稼働率を上げることが可能である。 This makes it possible to make bags independently for the bag making lines M1 and M2 while sharing the horizontal seal mechanism 20. For example, when one bag making line M1, M2 needs to make a bag in a continuous packaging state (a state in which two tubular films Ft are not side-sealed and joined together), The bag making lines M2 and M1 can be separated from the tubular film Ft one by one. As a result, it is possible to increase the operating rate of the bag making and packaging apparatus 1 while suppressing the occurrence rate of defective packaging.
　なお、横シール部と筒状フィルムの切り離しが異なる機構で行われる場合であっても、筒状フィルムの切り離しを行うカッター部３０が、分割刃物であるカッター３２Ａ，３２Ｂを、第１および第２製袋ラインＭ１，Ｍ２に対しそれぞれ備えていれば、袋Ｂの切り離しを製袋ライン毎に自由に決定でき、有利な効果が得られる。 Even when the horizontal seal portion and the tubular film are separated by different mechanisms, the cutter portion 30 that separates the tubular film is provided with the cutters 32A and 32B, which are divided blades, as the first and second cutters. If each of the bag making lines M1 and M2 is provided, the separation of the bag B can be freely determined for each bag making line, and an advantageous effect can be obtained.

　本実施形態に係る製袋包装装置１は、シート状のフィルムＦを筒状に成形するフォーマ１１２Ａ，１１２Ｂを具備する第１および第２製袋ラインＭ１，Ｍ２を有し、フィルムロールＲを共用する製袋包装装置である。製袋包装装置１は、切断部であるスリッタ５０と、バッファ部であるフィルム貯留部４０Ａ，４０Ｂとを備える。スリッタ５０は、フィルムロールＲから連続的に引き出される単一のシート状のフィルムＦを第１および第２製袋ラインＭ１，Ｍ２用に２つに切り離す。フィルム貯留部４０Ａ，４０Ｂは、スリッタ５０と第１および第２製袋ラインＭ１，Ｍ２がそれぞれに有するフォーマ１１２Ａ，１１２Ｂとの間に配置され、フィルムＦを一時的に製袋ラインＭ１，Ｍ２別に溜める。 (3-5)
The bag making and packaging apparatus 1 according to the present embodiment includes first and second bag making lines M1 and M2 having formers 112A and 112B for forming a sheet-like film F into a cylindrical shape, and shares a film roll R. This is a bag making and packaging device. The bag making and packaging apparatus 1 includes a slitter 50 that is a cutting portion and film storage portions 40A and 40B that are buffer portions. The slitter 50 separates the single sheet-like film F drawn continuously from the film roll R into two for the first and second bag making lines M1 and M2. The film storage units 40A and 40B are disposed between the slitter 50 and the formers 112A and 112B included in the first and second bag making lines M1 and M2, respectively, and the film F is temporarily separated by the bag making lines M1 and M2. Accumulate.
　このため、製袋ラインＭ１，Ｍ２別にフィルムＦの送り量を調整することができる。一方の製袋ラインＭ１，Ｍ２のフィルムＦだけを搬送して、他方の製袋ラインＭ２，Ｍ１のフィルムＦの搬送を停止するという操作も可能になるため、フィルムＦのロスの発生が抑制されやすい。 Therefore, the feeding amount of the film F can be adjusted separately for the bag making lines M1 and M2. Since the operation of conveying only the film F of one bag-making line M1, M2 and stopping the conveyance of the film F of the other bag-making line M2, M1 is also possible, the occurrence of loss of the film F is suppressed. Cheap.
　（３－６）
　本実施形態に係る製袋包装装置１は、フィルム貯留部４０Ａ，４０Ｂに溜められているフィルムＦの量を把握するバッファ量把握部５ａを有する。 (3-6)
The bag making and packaging apparatus 1 according to the present embodiment includes a buffer amount grasping unit 5a that grasps the amount of the film F stored in the film storing units 40A and 40B.
　このため、フィルム貯留部４０Ａ，４０Ｂに製袋可能な分量のフィルムＦが貯留されているか、あるいは、フィルム貯留部４０Ａ，４０ＢにフィルムＦが貯留可能かを判断して、製袋包装装置１の運転を停止しないよう、製袋ラインＭ１，Ｍ２毎にフィルムＦの調整を行うことが容易である。 For this reason, it is judged whether the film F of the amount which can be made in the film storage part 40A, 40B is stored, or the film F can be stored in the film storage part 40A, 40B. It is easy to adjust the film F for each bag making line M1, M2 so as not to stop the operation.
　さらに、各製袋ラインＭ１，Ｍ２の特性等の違いを原因として、各製袋ラインＭ１，Ｍ２のフィルム送り量が一時的に異なる場合であっても、フィルム貯留部４０Ａ，４０Ｂに溜められているフィルムＦの量を把握することでフィルム送り量の差が明確になり、フィルム送り量の補正を行うことが容易になる。 Further, even if the film feed amount of each bag making line M1, M2 is temporarily different due to the difference in the characteristics of each bag making line M1, M2, etc., it is stored in the film storage units 40A, 40B. By grasping the amount of the film F that is present, the difference in the film feed amount becomes clear, and it becomes easy to correct the film feed amount.

　本実施形態に係る製袋包装装置１は、縦シール機構１２Ａ，１２Ｂと、横シール機構２０とを有する。縦シール機構１２Ａ，１２Ｂは、フォーマ１１２Ａ，１１２Ｂにより筒状に形成されたフィルムＦｔの縦方向に重なる部分を連続的に縦シールする。横シール機構１２Ａ，１２Ｂは、縦シールがされた筒状フィルムＦｔを横シールして袋Ｂを形成する。フィルム貯留部４０Ａ，４０Ｂは、袋Ｂ１つ分のフィルムＦを溜めることが可能である。 (3-7)
The bag making and packaging apparatus 1 according to the present embodiment includes vertical seal mechanisms 12A and 12B and a horizontal seal mechanism 20. The vertical sealing mechanisms 12A and 12B continuously vertically seal the overlapping portions of the film Ft formed in a cylindrical shape by the formers 112A and 112B in the vertical direction. The lateral sealing mechanisms 12A and 12B form a bag B by laterally sealing the cylindrical film Ft that has been longitudinally sealed. The film storage units 40A and 40B can store the film F for one bag B.
　このため、被包装物Ｃが供給されないなどの原因で一方の製袋ラインＭ１，Ｍ２を１サイクル停止する必要がある場合にも、そのサイクルに本来使用されるはずであったフィルムＦをフィルム貯留部４０Ａ，４０Ｂに溜めることができ、フィルムＦのロスが発生しない。逆に、製袋ラインＭ１，Ｍ２は動かしながら、フィルムロールＲの搬送を１サイクル停止すべき状況が発生した場合にも、フィルム貯留部４０Ａ，４０Ｂに溜めておいたフィルムＦを利用することが可能で、製袋包装装置１を停止させる必要がない。つまり、フィルムＦのロスを抑制すると共に、製袋包装装置１の稼働率を上げることができる。 For this reason, even if it is necessary to stop one of the bag making lines M1 and M2 for one cycle due to the fact that the article to be packaged C is not supplied, the film F that should have been originally used in that cycle is stored in the film. The film F can be stored in the portions 40A and 40B, and the loss of the film F does not occur. Conversely, when the bag making lines M1 and M2 move and the situation where the conveyance of the film roll R should be stopped for one cycle occurs, the film F stored in the film storage units 40A and 40B can be used. It is possible and there is no need to stop the bag making and packaging apparatus 1. That is, the loss of the film F can be suppressed and the operating rate of the bag making and packaging apparatus 1 can be increased.

　本実施形態に係る製袋包装装置１は、シート状のフィルムＦを筒状に成形するフォーマ１１２Ａ，１１２Ｂを具備する第１および第２製袋ラインＭ１，Ｍ２を有し、フィルムロールＲを共用する製袋包装装置である。製袋包装装置１は、切断部であるスリッタ５０を備える。スリッタ５０は、フィルムロールＲから連続的に引き出される単一のシート状のフィルムＦを各製袋ラインＭ１，Ｍ２用に切り離す。スリッタ５０は、フィルムＦを切り離す切断ツールとしての第１切断部材５１および第２切断部材５２と、第１切断部材５１と第２切断部材５２の少なくとも一方が常にフィルムに接触した状態で、第１切断部材５１と第２切断部材５２との間で切断ツールを切り替える切替部と、を有する。すなわち、本実施形態に係る製袋包装装置１では、一方の切断部材５１，５２がフィルムから離れる時点で、他方の切断部材５２，５１が、フィルムＦの切り離しを開始している。 (3-8)
The bag making and packaging apparatus 1 according to the present embodiment includes first and second bag making lines M1 and M2 having formers 112A and 112B for forming a sheet-like film F into a cylindrical shape, and shares a film roll R. This is a bag making and packaging device. The bag making and packaging apparatus 1 includes a slitter 50 that is a cutting unit. The slitter 50 separates a single sheet-like film F drawn continuously from the film roll R for each bag making line M1, M2. The slitter 50 is a first cutting member 51 and a second cutting member 52 serving as cutting tools for cutting the film F, and the first cutting member 51 and the second cutting member 52 are always in contact with the film. A switching unit that switches a cutting tool between the cutting member 51 and the second cutting member 52. That is, in the bag making and packaging apparatus 1 according to the present embodiment, the other cutting members 52 and 51 start detaching the film F when the one cutting members 51 and 52 are separated from the film.
　より具体的には、スリッタ５０は、平面視において棒状のサポート部材５３を有する。サポート部材５３は、平面視においてサポート部材５３の両端に第１切断部材５１および第２切断部材５２がそれぞれ取り外し可能に固定される第１および第２固定部５３ａ，５３ｂと、第１固定部５３ａと第２固定部５３ｂとの間に配置される軸部５３ｃとを有する。サポート部材５３は、軸部５３ｃを中心として搬送されるフィルムＦのフィルム面に交差する方向に回動可能である。すなわち、軸部５３ｃが、切断ツールを第１切断部材５１と第２切断部材５２との間で切り替える切替部として機能する。 More specifically, the slitter 50 has a rod-like support member 53 in plan view. The support member 53 includes first and second fixing portions 53a and 53b to which the first cutting member 51 and the second cutting member 52 are detachably fixed to both ends of the support member 53 in plan view, and a first fixing portion 53a. And a shaft portion 53c disposed between the first fixing portion 53b and the second fixing portion 53b. The support member 53 is rotatable in a direction intersecting the film surface of the film F that is conveyed around the shaft portion 53c. That is, the shaft portion 53 c functions as a switching unit that switches the cutting tool between the first cutting member 51 and the second cutting member 52.
　このため、第１切断部材５１もしくは第２切断部材５２が常にフィルムＦを切断しているため、切断部材の切替の際にも製袋包装装置１を停止する必要がない。そのため、製袋包装装置１の稼働率を向上されることができる。 For this reason, since the first cutting member 51 or the second cutting member 52 always cuts the film F, it is not necessary to stop the bag making and packaging apparatus 1 even when the cutting member is switched. Therefore, the operation rate of the bag making and packaging apparatus 1 can be improved.
　また、本実施形態に係る製袋包装装置１では、軸部５３ｃは、モータにより自動で第１切断部材５１から第２切断部材５２に切断ツールを切り替える。 In the bag making and packaging apparatus 1 according to the present embodiment, the shaft portion 53c automatically switches the cutting tool from the first cutting member 51 to the second cutting member 52 by a motor.
　このため、作業員が手動で切断ツールを切り替える工数を削減できる。 For this reason, it is possible to reduce the man-hours for the operator to manually switch the cutting tool.

　上記の実施形態に係る製袋包装装置１では、製袋ラインを２つとしたが、これに限定されるものではなく、２つ以上の製袋ラインを有する製袋包装装置であってもよい。 <Modification>
(A)
In the bag making and packaging apparatus 1 according to the above embodiment, the number of bag making lines is two. However, the present invention is not limited to this and may be a bag making and packaging apparatus having two or more bag making lines.
　（Ｂ）
　上記の実施形態に係る製袋包装装置１では、フィルム貯留部４０Ａ，４０Ｂのフィルム貯留量を把握するためのセンサとして、可動ローラ４１Ａ，４１Ｂを駆動させる水平移動機構のモータの回転角度を把握するロータリーエンコーダ４２Ａ，４２Ｂを利用したが、これに限定されるものではない。 (B)
In the bag making and packaging apparatus 1 according to the above-described embodiment, the rotation angle of the motor of the horizontal movement mechanism that drives the movable rollers 41A and 41B is grasped as a sensor for grasping the film storage amount of the film storage portions 40A and 40B. Although the rotary encoders 42A and 42B are used, the present invention is not limited to this.
　例えば、フィルムの貯留量を可動ローラ４１Ａ，４１Ｂの移動量で把握する際に、リニアセンサや近接センサのような別のセンサが用いられてもよい。 For example, another sensor such as a linear sensor or a proximity sensor may be used when grasping the storage amount of the film by the movement amount of the movable rollers 41A and 41B.
　（Ｃ）
　上記の実施形態に係る製袋包装装置１では、計量機からの信号に基づいて、各製袋ラインＭ１，Ｍ２のカッター部３０Ａ，３０Ｂによる袋Ｂと筒状フィルムＦｔとの切り離しを決定しているが、これに限定されるものではない。例えば、後側シールジョー２１Ａ，２１Ｂとベース部材２３との間のバネ２４に作用する力、もしくはバネ２４の変位を検知して被包装物Ｃの噛み込みを検知し、カッター部３０Ａ，３０Ｂによる袋Ｂと筒状フィルムＦｔとの切り離しの実行の可否を決定してもよい。 (C)
In the bag making and packaging apparatus 1 according to the above embodiment, based on the signal from the weighing machine, the separation of the bag B and the tubular film Ft by the cutter units 30A and 30B of the bag making lines M1 and M2 is determined. However, it is not limited to this. For example, the force acting on the spring 24 between the rear seal jaws 21A, 21B and the base member 23, or the displacement of the spring 24 is detected to detect the biting of the article C to be packaged, and the cutter parts 30A, 30B. Whether or not the bag B and the tubular film Ft can be separated may be determined.

　上記の実施形態に係る製袋包装装置１では、フィルム貯留部４０Ａ，４０Ｂは、可動ローラ４１Ａ，４１Ｂを前後方向に動かすことでフィルムＦの貯留量を変更しているが、これに限定されるものではなく、例えば可動ローラ４１Ａ，４１Ｂを上下方向に稼動してもよい。 (D)
In the bag making and packaging apparatus 1 according to the above-described embodiment, the film storage units 40A and 40B change the storage amount of the film F by moving the movable rollers 41A and 41B in the front-rear direction. For example, the movable rollers 41A and 41B may be operated in the vertical direction.
　また、可動ローラ４１Ａ，４１Ｂの可動距離を長くとることで、もしくは、可動ローラ４１Ａ，４１Ｂを複数設けることで、１袋分以上のフィルムＦを貯留できるようにしてもよい。これにより、さらに製袋包装装置１の稼働率を高めることが可能になる。 Also, the film F of one bag or more may be stored by increasing the movable distance of the movable rollers 41A and 41B or by providing a plurality of movable rollers 41A and 41B. Thereby, the operation rate of the bag making and packaging apparatus 1 can be further increased.

　本発明の第２実施形態に係る製袋包装装置２０１について以下に説明する。なお、第２実施形態に係る製袋包装装置２０１は、第１実施形態に係る製袋包装装置１と共通する部分も多いため、第１実施形態との相違点についてのみ説明する。 <Second Embodiment>
A bag making and packaging apparatus 201 according to the second embodiment of the present invention will be described below. In addition, since the bag making packaging apparatus 201 which concerns on 2nd Embodiment has many parts which are common in the bag making packaging apparatus 1 which concerns on 1st Embodiment, only a different point from 1st Embodiment is demonstrated.
　（１）概略説明
　第２実施形態に係る製袋包装装置２０１は、第１実施形態に係る製袋包装装置１とその概略は同様である。 (1) Schematic Description The bag making and packaging apparatus 201 according to the second embodiment is substantially the same as the bag making and packaging apparatus 1 according to the first embodiment.
　（２）詳細説明
　第２実施形態に係る製袋包装装置２０１は、第１実施形態に係る製袋包装装置１と、主に以下の２点が相違する。図７および図８に基づいて説明する。 (2) Detailed Description The bag making and packaging apparatus 201 according to the second embodiment is mainly different from the bag making and packaging apparatus 1 according to the first embodiment in the following two points. This will be described with reference to FIGS.
　１点目は、フィルム搬送部２０４のフィルム搬送機構２６０は、フィルム貯留部４０Ａ，４０Ｂを有しない。 First, the film transport mechanism 260 of the film transport unit 204 does not have the film storage units 40A and 40B.
　２点目は、フィルムＦのスリッタ５０が、各製袋ラインＭ１，Ｍ２のフォーマ１１２Ａ，１１２Ｂのごく近傍に配置される。そのため、フィルムＦは分割後すぐにフォーマ１１２Ａ，１１２Ｂに供給され、第１実施形態では、スリッタとフォーマ１１２Ａ，１１２Ｂの間に蛇行防止のために配置されていた方向調整ローラが不要になる。 2nd, the slitter 50 of the film F is arrange | positioned in the very vicinity of former 112A, 112B of each bag making line M1, M2. Therefore, the film F is supplied to the formers 112A and 112B immediately after the division, and in the first embodiment, the direction adjusting roller arranged for preventing meandering between the slitter and the formers 112A and 112B becomes unnecessary.
　なお、フォーマ１１２Ａ，１１２Ｂは、フィルムＦのたるみや過剰な張りがない位置に、図８のように近接して配置される。 Note that the formers 112A and 112B are arranged close to each other at a position where there is no sagging or excessive tension of the film F as shown in FIG.
　その他の点については、同様であるため、説明は割愛する。 The other points are the same, so the explanation is omitted.
　（３）特徴
　本実施形態に係る製袋包装装置１は、シート状のフィルムＦを筒状に成形するフォーマ１１２Ａ，１１２Ｂを具備する第１および第２製袋ラインＭ１，Ｍ２を有し、フィルムロールＲを共用する製袋包装装置である。製袋包装装置１は、切断部であるスリッタ５０を備える。スリッタ５０は、フォーマ１１２Ａおよび１１２Ｂに近接して配置される。 (3) Features The bag making and packaging apparatus 1 according to this embodiment includes first and second bag making lines M1 and M2 including formers 112A and 112B for forming a sheet-like film F into a cylindrical shape. This is a bag making and packaging apparatus that shares the roll R. The bag making and packaging apparatus 1 includes a slitter 50 that is a cutting unit. The slitter 50 is disposed adjacent to the formers 112A and 112B.
　ここでは、フィルムＦが、フィルムロールＲの近傍ではなく、フォーマ１１２Ａ，１１２Ｂに近接した位置に配置されるため、フィルムＦの分割後にフィルムＦが蛇行しにくい。そのため、各製袋ラインＭ１，Ｍ２毎に必要であったフィルムＦの方向調整ローラが省略できる。簡素化した構成により製袋包装装置１のコストダウンを図ることができる。 Here, since the film F is arranged not in the vicinity of the film roll R but in a position close to the formers 112A and 112B, the film F is difficult to meander after the film F is divided. Therefore, the direction adjustment roller of the film F required for each bag making line M1, M2 can be omitted. The cost reduction of the bag making packaging apparatus 1 can be aimed at by the simplified structure.
