前記一対のシール体と前記搬出コンベヤの上流端部との間において前記物品の搬送路内の作動位置に進退するよう上下動する後耳折り体と、
一包装体における前後の耳部の間隔分だけ前記後耳折り体の作動位置より下流側で前記物品の搬送路内の作動位置に進退するよう上下動する前耳折り体とを備え、
前記前後の耳折り体は、前記作動位置に進出してシール直後の包装体の前後の耳部を各折り癖から折り曲げるよう構成したことを特徴とする。 In order to overcome the above-mentioned problems and achieve the intended object, a horizontal bag making and filling machine according to the invention of claim 1 is provided:
A pair of seal bodies that move vertically opposite to each other to obtain a package by performing transverse sealing and cutting on the tubular film before and after in the conveyance direction of the article in the tubular film,
A carry-out conveyor disposed on the downstream side of the seal body;
When the side seal is applied with the seal body to form the ear portion before and after the package body, a brazing means for giving a crease to the ear portion;
A rear-ear folding body that moves up and down so as to advance and retreat to an operating position in the conveyance path of the article between the pair of seal bodies and the upstream end of the carry-out conveyor;
A front ear folding body that moves up and down so as to advance and retreat to the operation position in the conveyance path of the article on the downstream side of the operation position of the rear ear folding body by an interval between the front and rear ear portions in one package .
The front and rear ear folding body, characterized in that the ear portions of the front and rear of the front SL operating position to be advanced sealed immediately after the package was configured to bend from the crease.

請求項２に係る発明では、前記一対のシール体は、筒状フィルムを挟持した状態で下流側に移動してから相互に離間した後、上流側に移動するよう構成され、
前記包装体の後側の耳部を折り曲げる前記後耳折り体は、両シール体がフィルムを解放した直後に作動位置に進出して下流側に移動するよう構成したことを特徴とする。 In the invention according to claim 2, the pair of seal bodies are configured to move to the upstream side after being separated from each other after moving to the downstream side in a state of sandwiching the tubular film,
The rear-ear folding body that folds the rear-side ear portion of the package is configured to advance to the operating position immediately after both seal bodies release the film and move to the downstream side.

請求項３に係る発明では、前記筒状フィルムは、上面側に縦シール部が形成され、前記前後の耳折り体は、作動位置に下側から進出して前後の耳部を上側に折り曲げるよう構成したことを特徴とする。 In the invention according to claim 3, the cylindrical film has a vertical seal portion formed on the upper surface side, and the front and rear ear folds are advanced from the lower side to the operating position so that the front and rear ear portions are bent upward. It is characterized by comprising.

請求項４に係る発明では、前記前後の耳折り体の間隔を調節可能に構成したことを特徴とする。 The invention according to claim 4 is characterized in that the distance between the front and rear ear folds is adjustable.

請求項５に係る発明では、前記前後の耳折り体が作動位置に進出するタイミングを可変可能に構成したことを特徴とする。 The invention according to claim 5 is characterized in that the timing at which the front and rear ear folds advance to the operating position is variable.

請求項１に係る発明によれば、前後の耳部の間隔分だけ離間する前後の耳折り体で包装体を前後から挟んだ状態で前後の耳部を折り曲げるよう構成したので、耳部の折り曲げに際して包装体が前後に移動するのを規制する部材を別途設ける必要はなく、構成を簡略化し得る。また、シール体により加熱されて軟化した耳部が初期の復元力を取り戻す前に、該耳部を折り癖の部分を基点として折り曲げることができ、前後の耳部が折り曲げられた状態を維持した包装体が得られる。すなわち、フィルムとして腰の強い素材を用いる場合であっても、耳部が確実に折り曲げられた状態を維持した包装体を製造し得る。
請求項２に係る発明によれば、シール体によるフィルムへの加熱終了直後に後耳折り体で折り曲げた耳部を、温度が低下するまで折り曲げ状態に保持することができ、耳部の折り曲げ状態は確実に維持される。
請求項３に係る発明によれば、包装体における縦シール部が形成された面側に耳部を折り曲げるので、反対面側の見栄えを良好にすることができる。
請求項４に係る発明によれば、包装体のサイズ変更に簡単に対応し得る。
請求項５に係る発明によれば、前後の耳部の長さの違い等に応じて、各耳部を最適なタイミングで折り曲げることができる。 According to the invention of claim 1, since it is configured such that the bend Ri folded ears before and after a state sandwiching the package from the back and forth around the ear folding body spaced intervals worth of front and rear ear portion, the ear portion It is not necessary to separately provide a member for restricting the package from moving back and forth during the folding, and the configuration can be simplified. Also, before the ears heated and softened by the sealing body regain their initial restoring force, the ears can be folded with the crease portion as a base point, and the front and rear ears are kept folded. A package is obtained. That is, even when a firm material is used as the film, it is possible to manufacture a package that maintains the state in which the ear portion is securely bent.
According to the invention which concerns on Claim 2, the ear | edge part bent by the rear ear | edge folding body immediately after completion | finish of the heating to the film by a sealing body can be hold | maintained in a bending state until temperature falls, The bending state of an ear | edge part Is reliably maintained.
According to the invention which concerns on Claim 3, since an ear | edge part is bend | folded to the surface side in which the vertical seal part in the package was formed, the appearance of the opposite surface side can be made favorable.
According to the invention which concerns on Claim 4, it can respond easily to the size change of a package.
According to the invention which concerns on Claim 5, according to the difference in the length of the front-and-rear ear | edge part, each ear | edge part can be bent at the optimal timing.
