This drive motor 7 drives the feed rollers 41, 41,... Of the roller conveyor means 4 all at once, and wraps P, P,. Is carried out in a predetermined direction.

本発明における、反転式包袋アンローダを用いた包袋搬送方法の実施例を図１から図８に基いて以下に説明する。まず、複数個の包袋Ｐを整列状態に面状に載置せるバッチトレー１をトレー搬送コンベア手段２に載置して（図１参照）、所定位置（ベース部材５における下向きのローラコンベア４の対向面）にまで搬送する（図２参照）。   An embodiment of a bag transport method using a reversible bag unloader according to the present invention will be described below with reference to FIGS. First, a batch tray 1 on which a plurality of wrapping bags P are placed in an aligned state is placed on a tray transporting conveyor means 2 (see FIG. 1), and a predetermined position (a downward roller conveyor 4 on a base member 5). (Refer to FIG. 2).

こうしてトレー搬送コンベア手段２に配設されて前記包袋Ｐ・Ｐ…を載置したバッチトレー１を、トレークランプ機構部３によって前後からクランプして上方へリフトせしめる（図３参照）。   In this way, the batch tray 1 placed on the tray conveying conveyor means 2 on which the wrapping bags P, P,... Are placed is clamped from the front and rear by the tray clamp mechanism 3 and lifted upward (see FIG. 3).

次に、ローラコンベア手段４に多数の送りローラ41・41…を所定の平行間隔で配設し、かつ、これら各々の送りローラ41と41との間に抑えバー42を出没可能に配設する一方、これら抑えバー42を突出動することによって前記トレークランプ機構部３でバッチトレー１と共にリフトされてくる包袋Ｐ・Ｐ…を当該トレーとの間に挟着する（図４参照）。   Next, a large number of feed rollers 41, 41,... Are arranged on the roller conveyor means 4 at predetermined parallel intervals, and a restraining bar 42 is arranged between the feed rollers 41 and 41 so as to be able to appear and retract. On the other hand, by projecting these holding bars 42, the packaging bags P, P,... Lifted together with the batch tray 1 by the tray clamp mechanism 3 are sandwiched between the trays (see FIG. 4).

この際、トレークランプ機構部３を伸縮動作してバッチトレー１をトレー搬送コンベア手段２から持ち上げるとともに、加えて、ベース部材５のローラコンベア手段４方向に付勢できるように構成することによって、包袋Ｐを確実に挟持することができる。   At this time, the tray clamp mechanism 3 is expanded and contracted to lift the batch tray 1 from the tray transporting conveyor means 2 and, in addition, the base member 5 can be biased in the direction of the roller conveyor means 4, The bag P can be securely held.

この際、バッチトレー１を搬送してきたトレー搬送コンベア手段２をローラコンベア手段４の傍らに退避させることにより、このローラコンベア手段４の作動時の干渉を防止することができる。   At this time, by retracting the tray conveying conveyor means 2 that has conveyed the batch tray 1 to the side of the roller conveyor means 4, it is possible to prevent interference during the operation of the roller conveyor means 4.

また、本実施例では、転回機構部６によって、ベース部材５におけるローラコンベア手段４の配設面を略水平に停止させることによって、包袋Ｐがズレたりせず、安定載置することができる。   Further, in this embodiment, the wrapping mechanism portion 6 stops the disposition surface of the roller conveyor means 4 in the base member 5 substantially horizontally, so that the wrapping bag P is not displaced and can be stably placed. .

然る後、転回機構部６によって、前記トレークランプ機構部３とローラコンベア手段４とを少なくとも一面に備えたベース部材５を転回して、これら包袋Ｐをバッチトレー１との間に挟着したローラコンベア手段４を上下に反転させて、かつ、バッチトレー１を上側へ移行せしめる（図５および６参照）。   After that, the base member 5 provided with the tray clamp mechanism 3 and the roller conveyor means 4 on at least one surface is turned by the turning mechanism 6 and the packaging bag P is sandwiched between the batch tray 1. The roller conveyor means 4 is turned upside down and the batch tray 1 is moved upward (see FIGS. 5 and 6).

そうして、このバッチトレー１を前記トレークランプ機構部３により分離し、前記ローラコンベア手段４の送りローラ41・41…を駆動モータ７によって一斉に駆動させて当該送りローラ上の包袋Ｐ・Ｐ…を所定方向へ搬出する（図７参照）。   Then, the batch tray 1 is separated by the tray clamp mechanism section 3, and the feed rollers 41, 41,... Of the roller conveyor means 4 are simultaneously driven by the drive motor 7, so that the wrapping bags P. P ... is carried out in a predetermined direction (see FIG. 7).

この際、この上向きに反転されたローラコンベア手段４の上向き載置面において、送りローラ41の移送沿路に沿って配設した取出コンベア８により、送りローラ41上に載置した前記包袋Ｐを受継して搬送することができ、必要に応じて、送りローラ41の回転による包袋Ｐの移送進行方向と取出コンベア８の移送方向とは同方向であるので、これらの移動速度を等しくして相対速度差をなくすことによって、包袋Ｐを引っ掛けることなくスムースに取り出すことも可能である（図８参照）。   At this time, the wrapping bag P placed on the feed roller 41 is taken up by the take-out conveyor 8 disposed along the transfer path of the feed roller 41 on the upward placement surface of the roller conveyor means 4 reversed upward. The transfer direction of the packaging bag P due to the rotation of the feed roller 41 and the transfer direction of the take-out conveyor 8 are the same as necessary, so that the moving speeds are equalized as necessary. By eliminating the relative speed difference, it is also possible to remove the bag P smoothly without being caught (see FIG. 8).

なお、本実施例では、図９に示すように、ベース部材５の表裏面それぞれにトレークランプ機構部３およびローラコンベア手段４を配設し、転回機構部６により、当該ベース部材５を回転軸61を対称にして下面と上面とを交互に反転せしめることができ、２倍の量の包袋Ｐの処理ができるように構成することも可能である。   In this embodiment, as shown in FIG. 9, the tray clamp mechanism portion 3 and the roller conveyor means 4 are disposed on the front and back surfaces of the base member 5, and the base member 5 is rotated by the turning mechanism portion 6. The lower surface and the upper surface can be alternately reversed with 61 being symmetrical, and it is also possible to configure so as to be able to process double the amount of sachets P.

本発明は、概ね上記のように構成されるが、本発明は図示の実施形態に限定されるものでは決してなく、「特許請求の範囲」の記載内において種々の変更が可能であって、例えば、ローラコンベア手段４の抑えバー42は、包袋Ｐを緩衝的に抑え付けるものであれば、スポンジ体や軟質ゴム体、ウレタン材などに限らず、他のプラスチック材料や発泡材料などを採用することもできる。   The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims. For example, The restraining bar 42 of the roller conveyor means 4 is not limited to a sponge body, a soft rubber body, a urethane material, etc., as long as it can restrain the wrapping bag P in a buffering manner, and other plastic materials or foam materials are employed. You can also.

また、ローラコンベア手段４の送りローラ41およびトレー搬送コンベア手段２の取り付け方向などのレイアウトを変更することによって、包袋Ｐの移送方向を適宜変更することも可能であり、更にまた、ベース部材５に、トレークランプ機構部３およびローラコンベア手段４を４面に配設して、転回機構部６を９０°ごとに反転させて、４倍の量の包袋Ｐの処理ができるように構成することも可能であり、これら何れのものも本発明の技術的範囲に属する。   Further, by changing the layout such as the mounting direction of the feed roller 41 of the roller conveyor means 4 and the tray conveying conveyor means 2, it is possible to appropriately change the transfer direction of the wrapping bag P. Furthermore, the base member 5 In addition, the tray clamp mechanism 3 and the roller conveyor means 4 are arranged on four sides, and the turning mechanism 6 is inverted every 90 ° to be able to process four times the amount of wrapping bags P. Any of these are within the scope of the present invention.
