Description

【考案の詳細な説明】[Detailed description of the device]

【０００１】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、熱可塑性フィルム袋の入口を瞬間的に加熱して接着するための自動 包装機用インパルスヒータに関するものである。 The present invention relates to an impulse heater for an automatic packaging machine for instantaneously heating and adhering an inlet of a thermoplastic film bag.

【０００２】[0002]

【従来の技術】[Prior art]

従来、この種のインパルスヒータは、図３に示すように一対の開閉板１、２の 間に充填物を収容したフィルム袋Ｆを挟圧して、その上端部を熱シールするよう になっている。一方の開閉板１には、絶縁材３を介して帯状のヒータ線４が取り 付けられ、このヒータ線４の表面は粘着性の接着剤によりテフロンテープ６が接 着され、フィルム袋Ｆにはテフロンテープ６を介して加熱するようにされている 。また、他方の開閉板２にはシリコンゴム等の緩衝材５が取り付けられている。 Conventionally, this type of impulse heater is designed to sandwich a film bag F containing a filling material between a pair of opening / closing plates 1 and 2 and heat seal the upper end thereof as shown in FIG. . A strip-shaped heater wire 4 is attached to one opening / closing plate 1 via an insulating material 3. The surface of the heater wire 4 is attached with a Teflon tape 6 by an adhesive agent, and the film bag F is attached to It is designed to be heated via the Teflon tape 6. Further, a cushioning material 5 such as silicon rubber is attached to the other opening / closing plate 2.

【０００３】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら上述した従来例は、ヒータ線４の表面にテフロンテープ６が被着 されているため、ヒータ線４に通電が繰り返されると、その都度、ヒータ線４が 伸縮してテフロンテープ６の表面に皺が発生し、フィルム袋Ｆにシール不足や仕 上り不良が発生し易いという問題がある。また、テフロンテープ６の粘着性接着 剤が断熱作用し、ヒータ線４の設定温度を高くする必要が生じている。また、テ フロンテープの焼損によってテープを交換する際に、ヒータ線に付着した接着剤 を除去しないと、新しいテープの接着剤とで２層の接着剤となるため、複数ヘッ ドの場合にはヘッド別に温度条件が変わってくる。更に、シングルヘッドにおい てもテープ交換前と条件が変わってくる。 However, in the above-mentioned conventional example, since the surface of the heater wire 4 is coated with the Teflon tape 6, the heater wire 4 expands and contracts on the surface of the Teflon tape 6 each time the heater wire 4 is repeatedly energized. There is a problem that wrinkles are generated, and the film bag F is apt to have insufficient sealing and poor finish. In addition, the adhesive agent of the Teflon tape 6 acts as a heat insulator, and it is necessary to raise the set temperature of the heater wire 4. Also, if the adhesive attached to the heater wire is not removed when replacing the tape due to burning of the Teflon tape, two layers of adhesive will be created with the adhesive of the new tape. The temperature conditions change depending on the head. Furthermore, even with a single head, the conditions differ from those before the tape was replaced.

【０００４】 本考案の目的は、上述した問題点を解消し、フィルム袋を良好に接着し、かつ 熱効率の良くテフロンテープの寿命を長くできる自動包装機用インパルスヒータ を提供することにある。An object of the present invention is to solve the above-mentioned problems, to provide an impulse heater for an automatic wrapping machine, which can adhere a film bag well, and have a good thermal efficiency and a long life of the Teflon tape.

【０００５】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

上述の目的を達成するための本考案に係る自動包装機用インパルスヒータは、 一方に発熱体を備えた一対の開閉板の間に熱可塑性のフィルム袋を挟圧し、前記 発熱体を加熱して前記フィルム袋を接着する自動包装機用インパルスヒータにお いて、前記発熱体の前面に離間してテフロンシートを吊り下げたことを特徴とす るものである。 The impulse heater for an automatic wrapping machine according to the present invention for achieving the above-mentioned object is configured such that a thermoplastic film bag is sandwiched between a pair of opening and closing plates having a heating element on one side to heat the heating element to heat the film. An impulse heater for an automatic wrapping machine for adhering a bag is characterized in that a Teflon sheet is hung at a distance from the front surface of the heating element.

【０００６】[0006]

【作用】[Action]

上述の構成を有する自動包装機用インパルスヒータは、発熱体の前面にテフロ ンシートを吊り下げたので、テフロンシートは開閉板間に挟圧されたときにのみ 発熱体に当接し、挟圧が解除されるとテフロンシートは発熱体から離れる。 In the impulse heater for the automatic packaging machine having the above-mentioned configuration, the Teflon sheet is hung on the front surface of the heating element, so the Teflon sheet comes into contact with the heating element only when it is clamped between the opening and closing plates, and the clamping pressure is released. Then, the Teflon sheet separates from the heating element.

【０００７】[0007]

【実施例】【Example】

本考案を図１、図２に図示の実施例に基づいて詳細に説明する。 図１は実施例の一部断面で示す構成図であり、図２はその部分拡大断面図であ る。充填物を収容した熱可塑性のフィルム袋Ｆは、図示しない搬送手段により開 閉板１１、１２の間に搬入される。これらの開閉板１１、１２は、架台１３に装 備された一対の駆動棒１４、１５にそれぞれ取り付けられ、駆動棒１４、１５の 一方が駆動されることにより、フィルム袋Ｆが開閉板１１、１２の間に挟圧され るようになっている。また、一方の開閉板１１には絶縁材１６が貼着等により取 り付けられ、この絶縁材１６の表面に帯状のヒータ線１７が取り付けられている 。また、他方の開閉板１２にはシリコンゴム等から成る緩衝材１８が取り付けら れている。開閉板１１の上部には、テフロンシート１９の上端を貼着した断面Ｌ 字状のシート保持具２０が、シート取付台２１に取付ボルト２２により取り付け られ、ヒータ線１７の前面に吊り下げられたテフロンシート１９は、ヒータ線１ ７から離間するようになっている。 The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a configuration diagram showing a partial cross section of the embodiment, and FIG. 2 is a partially enlarged cross sectional view thereof. The thermoplastic film bag F containing the filling material is carried in between the opening and closing plates 11 and 12 by a conveying means (not shown). These opening / closing plates 11 and 12 are attached to a pair of drive rods 14 and 15 mounted on a pedestal 13, respectively, and by driving one of the driving rods 14 and 15, the film bag F is opened / closed. It is designed to be pinched between 12 pieces. An insulating material 16 is attached to one of the opening / closing plates 11 by sticking or the like, and a belt-shaped heater wire 17 is attached to the surface of the insulating material 16. A cushioning material 18 made of silicon rubber or the like is attached to the other opening / closing plate 12. A sheet holder 20 having an L-shaped cross section to which an upper end of a Teflon sheet 19 is attached is attached to an upper portion of the opening / closing plate 11 by a mounting bolt 22 on a sheet mounting base 21 and is hung in front of the heater wire 17. The Teflon sheet 19 is separated from the heater wire 17.

【０００８】 このような構成により、充填物を収容したフィルム袋Ｆが、図示しない搬送手 段により緩衝材１８とテフロンシート１９の間に搬送されると、開閉板１１、１ ２の一方又は双方が移動してフィルム袋Ｆの両側を挟圧する。このとき、フィル ム袋Ｆの片面は吊り下げられたテフロンシート１９を介してヒータ線１７に圧接 し、他面は緩衝材１８に圧接した状態になる。With such a configuration, when the film bag F containing the filler is transported between the cushioning material 18 and the Teflon sheet 19 by a transporting means (not shown), one or both of the opening / closing plates 11, 12 are opened. Moves to pinch both sides of the film bag F. At this time, one surface of the film bag F is in pressure contact with the heater wire 17 through the Teflon sheet 19 that is suspended, and the other surface is in pressure contact with the cushioning material 18.

【０００９】 この状態でヒータ線１７に瞬間的に通電するとヒータ線１７が発熱し、その熱 がテフロンシート１９を介してフィルム袋Ｆに伝えられ、フィルム袋Ｆが熱シー ルされる。フィルム袋Ｆが熱シールされた後に、開閉板１１、１２の一方又は双 方が移動してフィルム袋Ｆの挟圧を開放し、フィルム袋Ｆは図示しない搬送手段 により搬出され、テフロンシート１９はヒータ線１７から離れて吊り下げられた 元の状態に戻る。When the heater wire 17 is momentarily energized in this state, the heater wire 17 generates heat, and the heat is transferred to the film bag F via the Teflon sheet 19, and the film bag F is heat-sealed. After the film bag F is heat-sealed, one or both of the opening and closing plates 11 and 12 moves to release the pinching pressure of the film bag F, and the film bag F is carried out by a conveying means (not shown), and the Teflon sheet 19 is It returns to the original state in which it is suspended from the heater wire 17.

【００１０】 このように、本実施例のテフロンシート１９は挟圧時のみにヒータ線１７に接 触し、通電時にはテフロンシート１９の一端は自由端になって自由に伸展する。 通電が停止されて挟圧が開放されると、テフロンシート１９の熱はヒータ線１７ から離れて吊り下げられた状態になって放出されるため、ヒータ線１７に繰り返 し通電されても、テフロンシート１９に皺が発生することはない。 なお、開閉板１１の内部に空間を設けると、放熱効果が上がってヒータ線１７ の変形が少なくなる。As described above, the Teflon sheet 19 of this embodiment is in contact with the heater wire 17 only when it is pressed, and one end of the Teflon sheet 19 becomes a free end and freely extends when energized. When the energization is stopped and the pinching force is released, the heat of the Teflon sheet 19 is released from the heater wire 17 in a suspended state, so even if the heater wire 17 is repeatedly energized, Wrinkles do not occur on the Teflon sheet 19. If a space is provided inside the opening / closing plate 11, the heat radiation effect is improved and the deformation of the heater wire 17 is reduced.

【考案の効果】[Effect of device]

以上説明したように本考案に係る自動包装機用インパルスヒータは、発熱体を 覆うようにテフロンシートを吊り下げたので、発熱体に通電が繰り返されてもテ フロンシートは自由に伸縮し、テフロンシートの熱は両面から効率良く放出され るため、テフロンシートに皺が発生することはなく、フィルム袋を良好に接着す ることができる。 As described above, in the impulse heater for the automatic packaging machine according to the present invention, the Teflon sheet is hung so as to cover the heating element. Therefore, even if the heating element is repeatedly energized, the Teflon sheet freely expands and contracts, and the Teflon sheet is expanded and contracted. Since the heat of the sheet is efficiently released from both sides, wrinkles do not occur on the Teflon sheet, and the film bag can be bonded well.
