Description

本発明は物品包装の技術分野に属する。   The present invention belongs to the technical field of article packaging.

一般に、合成樹脂等でなる熱溶融性のフィルムを物品供給用チューブの周囲で筒状に曲成し、重なり合ったフィルムの側縁部を縦シール装置で加熱溶着して縦にシールすると共に、その筒状のフィルムを横シール装置で加熱溶着して横にシールすることで袋を製作しながら、その袋に前記チューブを介して物品を導入充填する構成の包装機が広く知られている。このような包装機においては、例えば特許文献１に開示されているように、横シール領域内のほぼ中央の部位を横に切断して袋を１つづつ切り離す切断装置が備えられる。しかし、図８に例示するように、従来、この切断装置の切刃（切断部材）ａは横シール装置のシールジョー（シール部材）ｂのシール面ｃから突出して設けられてはいるものの、シールジョーｂと切刃ａとの間にはどうしても機械的な間隙ｄができるため、横シール領域と袋ｅの切断端部との間に非溶着部分ｆが発生し、これがフレアとなってめくれるため袋ｅの見栄えが低下する不具合があった。   Generally, a heat-meltable film made of a synthetic resin or the like is bent into a cylindrical shape around an article supply tube, and the side edges of the overlapped films are heat-welded with a vertical seal device and vertically sealed. 2. Description of the Related Art A packaging machine configured to introduce and fill articles through a tube while manufacturing a bag by heat-welding a cylindrical film with a horizontal sealing device and sealing it horizontally is widely known. In such a packaging machine, for example, as disclosed in Patent Document 1, a cutting device that cuts a substantially central portion in the lateral seal region laterally to separate the bags one by one is provided. However, as illustrated in FIG. 8, the cutting blade (cutting member) a of this cutting device is conventionally provided so as to protrude from the sealing surface c of the sealing jaw (seal member) b of the horizontal sealing device. Since a mechanical gap d is inevitably formed between the jaw b and the cutting edge a, a non-welded portion f is generated between the lateral seal region and the cut end portion of the bag e, and this becomes a flare. There was a problem that the appearance of the bag e deteriorated.

このような問題に対処するものとして、例えば特許文献２に開示されているように、フィルムを圧力のみで切断するのではなく、フィルムを加熱溶融もして切断する溶断式の切断装置（溶断装置）を採用することが考えられる。これによれば、図９に例示するように、たとえその溶断装置の切断部材ｇとシール装置のシールジョーｂとの間に間隙ｄが残っても、袋ｅの切断端部が前記切断部材ｇで溶融接合ｈしてフレアの発生が抑制される。また、これにより袋ｅの密封性もより一層向上することが期待される。   As a countermeasure against such a problem, for example, as disclosed in Patent Document 2, a fusing-type cutting device (fusing device) that cuts a film by heating and melting instead of cutting the film only by pressure. Can be considered. According to this, as illustrated in FIG. 9, even if a gap d remains between the cutting member g of the fusing device and the sealing jaw b of the sealing device, the cut end of the bag e remains at the cutting member g. Therefore, the occurrence of flare is suppressed by fusion bonding. Further, it is expected that the sealing property of the bag e is further improved.

しかし、従来、前記溶断装置を備えたシール装置では、シール装置のシール部材の加熱も溶断装置の切断部材の加熱も共通する単一のヒータで行っていたので、次のような不具合が生じていた。すなわち、そもそもフィルムをシール装置で加熱溶着してシールする温度と、フィルムを溶断装置で加熱溶融して切断する温度とは相互に異なり、一般に、シール温度は溶断温度よりも低い。それゆえ、フィルムがシール領域で溶融して変形することを避けるために、どうしてもヒータの設定温度は低いほうのシール温度に調節することになる。すると、溶断装置の切断部材の加熱熱量が不足してフィルムが速やかに溶融せず、熱だけではフィルムを速やかに切断することが困難になるので、切断部材の形状はフィルムに高圧が作用するように前記切刃のごとく先端の尖ったものが使用される傾向にある。その結果、切断部材の先端の耐久性が低下し、頻繁に切断部材の先端を研摩したり、あるいは切断部材を取り替える必要が生じて、時間やコストが余計にかかってしまうことになるのである。   However, conventionally, in the sealing device provided with the fusing device, since the heating of the sealing member of the sealing device and the heating of the cutting member of the fusing device are performed by a single heater, the following problems have occurred. It was. That is, the temperature at which a film is heat-welded and sealed with a sealing device is different from the temperature at which a film is heat-melted and cut with a fusing device, and generally the sealing temperature is lower than the fusing temperature. Therefore, in order to avoid the film from melting and deforming in the seal region, the set temperature of the heater is inevitably adjusted to the lower seal temperature. Then, the amount of heat of heating of the cutting member of the fusing device is insufficient and the film does not melt quickly, and it becomes difficult to cut the film quickly only with heat, so the shape of the cutting member seems to act on the film at high pressure. In addition, there is a tendency to use a sharp tip like the cutting edge. As a result, the durability of the tip of the cutting member is lowered, and it becomes necessary to frequently polish the tip of the cutting member or replace the cutting member, resulting in extra time and cost.

本発明は、前記のような不具合に対処するもので、溶断装置を備えたシール装置において、シール部材を適切なシール温度に加熱して、フィルムがシール領域で溶融して変形することを避けながら、切断部材もまた適切な溶断温度に加熱して、フィルムを速やかに溶断することのできるシール装置の提供を課題とする。   The present invention addresses the problems as described above, and in a sealing device equipped with a fusing device, the sealing member is heated to an appropriate sealing temperature while avoiding the film melting and deforming in the sealing region.

However, in the present embodiment, the pressing surface 16 a of the cutter member 16 is provided by a wedge-shaped member 17 fitted to the front surface of the cutter member 16. A first fusing heater 19 and a second fusing heater 20 for heating the members 16 and 18 are provided for each of the cutter member 16 and the receiving member 18, and the cutter member 16 and the fusing heaters 19 and 20 are disposed in the vicinity of the fusing heaters 19 and 20.

Further, various conditions information such as the material of the film F manually input from the operation panel 90, the thickness of the film F, the welding time, and the fusing time are input.

そして、コントロールユニット１００は、前記各信号及び情報に基づいて、第１、第２の溶断ヒータ１９，２０を制御してカッタ部材１６の溶断温度及び受け部材１８の溶断温度をそれぞれ所定の目標温度（例えば１６０〜１７０℃等）に調節し、また、シールヒータ１４…１４を制御してシールジョー１３…１３の各部位１３ａ，１３ｂ：１３ａ，１３ｂのシール温度を所定の目標温度（例えば９０℃〜１２０℃等）に調節する。さらに、溶断アクチュエータ２５を制御してカッタ部材１６及び受け部材１８の溶断圧力を所定の目標圧力に調節する。   The control unit 100 controls the first and second fusing heaters 19 and 20 on the basis of the signals and information to set the fusing temperature of the cutter member 16 and the fusing temperature of the receiving member 18 to a predetermined target temperature. (For example, 160 to 170 ° C.) and the seal heaters 14... 14 are controlled to set the seal temperatures of the portions 13 a and 13 b: 13 a and 13 b of the seal jaws 13 to 13 to a predetermined target temperature (for example, 90 ° C.). ˜120 ° C.). Further, the fusing actuator 25 is controlled to adjust the fusing pressure of the cutter member 16 and the receiving member 18 to a predetermined target pressure.

その場合に、コントロールユニット１００は、前記第１、第２の溶断温度センサ２１，２２の検出結果に基づいて、前記第１、第２の溶断ヒータ１９，２０をフィードバック制御する。   In that case, the control unit 100 feedback-controls the first and second fusing heaters 19 and 20 based on the detection results of the first and second fusing temperature sensors 21 and 22.

しかも、コントロールユニット１００は、前記第１、第２の溶断ヒータ１９，２０をそれぞれ個別に制御して、カッタ部材１６及び受け部材１８をそれぞれ異なる溶断温度（例えばカッタ部材１６は１６０℃で、受け部材１８は１７０℃等）に調節する。   In addition, the control unit 100 individually controls the first and second fusing heaters 19 and 20, respectively, so that the cutting member 16 and the receiving member 18 are received at different fusing temperatures (for example, the cutting member 16 is 160 ° C.). The member 18 is adjusted to 170 ° C. or the like.

また、コントロールユニット１００は、前記シールヒータ１４…１４をそれぞれ個別に制御して、シールジョー１３，１３の各部位１３ａ，１３ｂ：１３ａ，１３ｂをそれぞれ異なるシール温度（例えば右上の部位１３ａは９０℃で、右下の部位１３ｂは１００℃、及び左上の部位１３ａは１１０℃で、左下の部位１３ｂは１２０℃等）に調節する。   Further, the control unit 100 individually controls the seal heaters 14... 14 so that the portions 13a and 13b of the seal jaws 13 and 13: 13a and 13b have different seal temperatures (for example, the upper right portion 13a is 90 ° C.). The lower right portion 13b is adjusted to 100 ° C., the upper left portion 13a is adjusted to 110 ° C., and the lower left portion 13b is adjusted to 120 ° C.

さらに、コントロールユニット１００は、前記溶断アクチュエータ２５を制御してカッタ部材１６及び受け部材１８の溶断動作を調節する。例えば図６に例示するように、シールジョー１３，１３がＤ字旋回に伴い対接してフィルムＦの挟み付けを開始した後に、カッタ部材１６を押し出して受け部材１８との間でフィルムＦを押圧してフィルムＦの溶断を開始すると共に、シールジョー１３，１３がＤ字旋回に伴い離反してフィルムＦの挟み付けを終了する前に、カッタ部材１６を後退させてフィルムＦの溶断を終了する。つまり、溶断開始時刻をシール開始時刻より遅くしながらも、溶断完了時刻ｔｃをシール完了時刻ｔｓより早くするのである。この場合、シールジョー１３，１３が時刻ｔｓに離反したときに袋Ｘは筒状フィルムＦと切り離されて落下する。   Further, the control unit 100 controls the fusing actuator 25 to adjust the fusing operation of the cutter member 16 and the receiving member 18. For example, as illustrated in FIG. 6, after the sealing jaws 13, 13 come into contact with the D-shaped rotation and start to sandwich the film F, the cutter member 16 is pushed out to press the film F between the receiving member 18. Then, the fusing of the film F is started, and before the sealing jaws 13 and 13 are separated by the D-shaped rotation and the clamping of the film F is finished, the cutter member 16 is moved backward to finish the fusing of the film F. . That is, the fusing completion time tc is made earlier than the sealing completion time ts while the fusing start time is later than the sealing start time. In this case, when the sealing jaws 13 and 13 are separated at time ts, the bag X is separated from the tubular film F and dropped.

また、例えば図７に例示するように、シールジョー１３，１３がＤ字旋回に伴い対接してフィルムＦの挟み付けを開始する前に、カッタ部材１６を押し出して受け部材１８との間でフィルムＦを押圧してフィルムＦの溶断を開始すると共に、シールジョー１３，１３がＤ字旋回に伴い離反してフィルムＦの挟み付けを終了した後に、カッタ部材１６を後退させるようにしてもよい。ただし、シールジョー１３，１３が離反する前の時刻ｔｃに、溶断は完了している。つまり、溶断開始時刻をシール開始時刻より早くし、かつ溶断完了時刻ｔｃもシール完了時刻ｔｓより早くするのである。この場合も、シールジョー１３，１３が時刻ｔｓに離反したときに袋Ｘは落下する。   For example, as illustrated in FIG. 7, before the sealing jaws 13 and 13 come into contact with the D-shaped rotation and start to sandwich the film F, the cutter member 16 is pushed out and the film is received between the receiving member 18. The cutting of the film F may be started by pressing F, and the cutter members 16 may be retracted after the sealing jaws 13 and 13 are separated along with the D-shaped rotation and the film F has been clamped. However, the fusing is completed at time tc before the seal jaws 13 and 13 are separated. In other words, the fusing start time is set earlier than the seal start time, and the fusing completion time tc is also set earlier than the sealing completion time ts. Also in this case, the bag X falls when the sealing jaws 13 and 13 are separated at time ts.

次に、以上のように構成したこの横シール装置１０ないし包装機１の特徴を述べる。まず、フィルムＦを溶着してシールするシールジョー１３，１３と、そのシール領域Ａ内の所定の部位を溶融して切断する切断部材１６，１８とを有するシール装置１０において、前記シールジョー１３，１３を加熱するシールヒータ１４…１４と、前記切断部材１６，１８を加熱する溶断ヒータ１９，２０とを個別に設けたから、それぞれ異なるシール温度と溶断温度との両方に適正に対応することが可能となり、シールヒータ１４…１４で相対的に低いシール温度を設定しながら、溶断ヒータ１９，２０で相対的に高い溶断温度を設定することができて、その結果、フィルムＦがシール領域Ａで溶融して変形することを避けながら、同じフィルムＦを速やかに溶断することが可能となる。   Next, the features of the horizontal sealing device 10 or the packaging machine 1 configured as described above will be described. First, in the sealing device 10 having the sealing jaws 13 and 13 for welding and sealing the film F and the cutting members 16 and 18 for melting and cutting a predetermined portion in the sealing region A, the sealing jaws 13 and 13 Since the seal heaters 14... 14 for heating 13 and the fusing heaters 19 and 20 for heating the cutting members 16 and 18 are individually provided, it is possible to appropriately cope with both different sealing temperatures and fusing temperatures. The relatively high fusing temperature can be set by the fusing heaters 19 and 20 while the relatively low sealing temperature is set by the seal heaters 14..., And as a result, the film F is melted in the seal region A. Thus, it is possible to quickly melt the same film F while avoiding deformation.

次に、溶断ヒータ１９，２０を制御して切断部材１６，１８の加熱温度を目標温度に調節するコントロールユニット１００を設けたから、例えばフィルムＦの種類や厚みあるいは溶断時間等の諸条件に応じて溶断温度をいろいろに変更することができ、フィルムＦの溶断を精度よく行うことが可能となる。   Next, since the control unit 100 that controls the fusing heaters 19 and 20 to adjust the heating temperature of the cutting members 16 and 18 to the target temperature is provided, for example, depending on various conditions such as the type and thickness of the film F or fusing time. The fusing temperature can be changed variously, and the fusing of the film F can be performed with high accuracy.

次に、切断部材１６，１８の温度を検出する溶断温度センサ２１，２２を備え、前記コントロールユニット１００は前記センサ２１，２２の検出結果に基づいて溶断ヒータ１９，２０をフィードバック制御するから、溶断温度をフィードバック制御によって短時間に制度よく変更することが可能となる。   Next, fusing temperature sensors 21 and 22 for detecting the temperature of the cutting members 16 and 18 are provided, and the control unit 100 feedback controls the fusing heaters 19 and 20 based on the detection results of the sensors 21 and 22. The temperature can be changed systematically in a short time by feedback control.

なお、これに代えて、コントロールユニット１００は溶断ヒータ１９，２０をオープン制御するようにしてもよい。例えば、操作パネル９０を操作して溶断温度を指定するだけで、予め決められた電流が溶断ヒータ１９，２０に流されて、該ヒータ１９，２０が予め決められた熱量を発生するようにする。この場合は、溶断温度をオープン制御によって簡単な構成で容易に変更することができる。   Instead of this, the control unit 100 may perform open control of the fusing heaters 19 and 20. For example, only by operating the operation panel 90 and specifying the fusing temperature, a predetermined current is passed through the fusing heaters 19 and 20 so that the heaters 19 and 20 generate a predetermined amount of heat. . In this case, the fusing temperature can be easily changed with a simple configuration by open control.

次に、シールジョー１３，１３はフィルムＦを挟み付けるように１対設けられていると共に、切断部材１６，１８は前記シールジョー１３，１３に備えられてフィルムＦを押圧するように１対設けられているから、フィルムＦの溶断は加熱溶融だけでなく加圧もされてより円滑に行われる。   Next, a pair of sealing jaws 13 and 13 are provided so as to sandwich the film F, and a pair of cutting members 16 and 18 are provided so as to press the film F provided on the sealing jaws 13 and 13. Therefore, the fusing of the film F is performed more smoothly by being pressurized as well as heated and melted.

しかも、シールジョー１３，１３のシール面が平坦であるから、該シールジョー１３，１３によるフィルムＦのシール動作（ひいては包装動作）が高速で行われても、該ジョー１３，１３同士の対接のずれが低減されて、位置決め精度が高まり、その結果、切断部材１６，１８によるフィルムＦの溶断動作もまた精度よく確実、円滑に行なわれる。   In addition, since the sealing surfaces of the sealing jaws 13 and 13 are flat, even when the sealing operation (and consequently the packaging operation) of the film F by the sealing jaws 13 and 13 is performed at high speed, the jaws 13 and 13 are in contact with each other. As a result, the fusing operation of the film F by the cutting members 16 and 18 is also accurately and surely performed smoothly.

次に、切断部材１６，１８の一方のカッタ部材１６を押圧面１６ａが尖った刃形状とし、他方の受け部材１８を押圧面１８ａが平坦な受け形状としたから、フィルムＦに作用する圧力が高められてフィルムＦの溶断がより一層円滑に行われる。また、カッタ部材１６の押圧面１６ａが狭いから、カッタ部材１６がフィルムＦと接触したときに温度低下することが抑制され、この点からもフィルムＦの溶断が支障なく円滑に行われる。   Next, since one cutter member 16 of the cutting members 16 and 18 has a blade shape with a sharp pressing surface 16a and the other receiving member 18 has a pressing shape with a flat pressing surface 18a, the pressure acting on the film F is increased. As a result, the fusing of the film F is performed more smoothly. Further, since the pressing surface 16a of the cutter member 16 is narrow, the temperature drop is suppressed when the cutter member 16 comes into contact with the film F, and also from this point, the fusing of the film F is performed smoothly without any trouble.

次に、溶断ヒータ１９，２０を切断部材１６，１８毎に設け、前記コントロールユニット１００は前記切断部材１６，１８毎に温度調節するから、フィルムＦを裏表両面から速やかに加熱することができ、フィルムＦの溶断が短時間で完遂する。しかも、フィルムＦを裏表両面から異なる温度で加熱することができ、フィルムＦの溶断をより精度よく行うことができる。   Next, since the fusing heaters 19 and 20 are provided for each of the cutting members 16 and 18, and the control unit 100 adjusts the temperature for each of the cutting members 16 and 18, the film F can be quickly heated from both the front and back surfaces. The fusing of the film F is completed in a short time. In addition, the film F can be heated at different temperatures from the front and back surfaces, and the film F can be melted more accurately.

次に、切断部材１６，１８の少なくとも一方のカッタ部材１６をシールジョー１３に対して押圧方向に相対移動自在に設けたうえで、その相対移動自在のカッタ部材１６を駆動する溶断アクチュエータ２５を備えたから、シールジョー１３に具備したカッタ部材１６を該シールジョー１３に対して相対移動させることにより、前記カッタ部材１６をシールジョー１３とは独立してフィルムＦに対して進退させることができ、その結果、カッタ部材１６及び受け部材１８によるフィルムＦの加熱や加圧を必要に応じて行うことが可能となる。   Next, at least one cutter member 16 of the cutting members 16 and 18 is provided so as to be relatively movable in the pressing direction with respect to the sealing jaw 13, and a fusing actuator 25 for driving the relatively movable cutter member 16 is provided. Therefore, by moving the cutter member 16 provided on the seal jaw 13 relative to the seal jaw 13, the cutter member 16 can be moved forward and backward with respect to the film F independently of the seal jaw 13, As a result, the film F can be heated and pressurized by the cutter member 16 and the receiving member 18 as necessary.

したがって、状況によっては、例えば異常品を包装したような場合に、正常品と区別するために、フィルムＦを切断しない動作や、フィルムＦに切り目だけを付与する動作等の、連包動作も実行可能となる。   Therefore, depending on the situation, for example, when abnormal products are packaged, in order to distinguish them from normal products, a continuous operation such as an operation that does not cut the film F or an operation that gives only cuts to the film F is also performed. It becomes possible.

次に、前記溶断アクチュエータ２５を制御して前記切断部材１６，１８の切断動作を調節するコントロールユニット１００を備えたから、シールジョー１３，１３によるフィルムＦのシール動作と、切断部材１６，１８による同フィルムＦの溶断動作とを、様々なタイミングで互いに影響されることなく個別に開始及び終了させることができる。   Next, since the control unit 100 for controlling the cutting operation of the cutting members 16 and 18 by controlling the fusing actuator 25 is provided, the sealing operation of the film F by the sealing jaws 13 and 13 and the same operation by the cutting members 16 and 18 are provided. The fusing operation of the film F can be started and ended individually without being influenced by each other at various timings.

次に、溶断アクチュエータ２５を制御して切断部材１６，１８の切断圧力を調節するコントロールユニット１００を備えたから、溶断圧力の調節を行うことによって、例えばフィルムＦの種類や厚みあるいは溶断時間等の諸条件に応じて溶断圧力をいろいろ変更することができ、フィルムＦの溶断を精度よく行うことが可能となる。   Next, since the control unit 100 for adjusting the cutting pressure of the cutting members 16 and 18 by controlling the fusing actuator 25 is provided, by adjusting the fusing pressure, for example, various kinds of film F, thickness, fusing time, etc. Various fusing pressures can be changed according to the conditions, and the fusing of the film F can be performed with high accuracy.

次に、シールヒータ１４…１４を制御してシールジョー１３，１３の加熱温度を目標温度に調節するコントロールユニット１００を備えたから、シール温度の調節を行うことによって、例えばフィルムＦの種類や厚みあるいはシール時間等の諸条件に応じてシール温度をいろいろ変更することができ、フィルムＦの溶着を精度よく行うことが可能となる。   Next, since the control unit 100 for adjusting the heating temperature of the seal jaws 13 and 13 to the target temperature by controlling the seal heaters 14... 14 is provided, by adjusting the seal temperature, for example, the type or thickness of the film F or Various sealing temperatures can be changed according to various conditions such as the sealing time, and the film F can be welded with high accuracy.

そして、シールジョー１３，１３は切断部材１６，１８で複数の部位１３ａ，１３ｂに区切られ、前記シールヒータ１４…１４は前記区切られた部位１３ａ，１３ｂ毎に設けられ、前記コントロールユニット１００は前記部位毎１３ａ，１３ｂに温度調節するから、切断部材１６，１８の加熱の影響を考慮して、切断部材１６，１８で区切られたシールジョー１３，１３の各部位１３ａ，１３ｂの加熱温度をいろいろ変更することができ、フィルムＦの溶着をより精度よく行うことが可能となる。   The sealing jaws 13, 13 are divided into a plurality of parts 13a, 13b by cutting members 16, 18, the seal heaters 14 ... 14 are provided for the divided parts 13a, 13b, and the control unit 100 is Since the temperature is adjusted to each part 13a and 13b, the heating temperature of each part 13a and 13b of the seal jaws 13 and 13 divided by the cutting members 16 and 18 is considered in consideration of the effect of heating of the cutting members 16 and 18. Therefore, the film F can be welded with higher accuracy.

以上説明した実施の形態は、本発明の最良の実施の形態ではあるが、特許請求の範囲を逸脱しない限りなお種々の選択や変更あるいは修正が可能であることはいうまでもない。   Although the embodiment described above is the best embodiment of the present invention, it goes without saying that various selections, changes or modifications can be made without departing from the scope of the claims.

以上具体例を挙げて詳しく説明したように、本発明は、シール部材を適切なシール温度に加熱することによりフィルムがシール領域で溶融して変形することを避けつつ、切断部材を適切な溶断温度に加熱することによりフィルムを速やかに溶断することの可能なシール装置及びそれを備えた包装機を提供する。本発明は、物品包装の技術分野において広範な産業上の利用可能性が期待される。   As described above in detail with reference to specific examples, the present invention can prevent the film from melting and deforming in the sealing region by heating the sealing member to an appropriate sealing temperature, and the cutting member to an appropriate fusing temperature. The present invention provides a sealing device capable of quickly fusing a film by heating to a wrapping machine and a packaging machine including the same.
