Zusammenfassung:The present invention relates to a film wrapping machine for a stretchable film packaging device. The film wrapping machine for a stretchable film packaging device comprises: a frame which has vertical bars extending upward and mutually spaced to provide a mobile allowance space below for the entry of the wrapping target product; a pair of suction pads which move in a mutually spaced direction while a front end portion of the stretchable film supplied from the film supplier is opened and each stretchable film is vacuum-suctioned; a film clamping unit which has a plurality of clamps which pinch the front end portion of the stretchable film opened by the suction pads and process the stretchable film, which has been cut and joined at the top by the film supplier, into a wrinkled state, and during the lowering of the vertical bars, the stretchable film is processed to be wrapped around the product; and a control unit which controls the operation of the film clamping part and the film supplying part to lower along the vertical bars while the clamps of the film clamping part pinch the stretchable film, and to rise along the vertical bars while the clamps of the film clamping part release the pinch of the stretchable film. The present invention can support packaging operations for products without the need for a separate heat-shrinking process. 본 발명은 신축필름 포장장치용 필름 랩핑기에 관한 것으로서, 하부에 랩핑 대상 물품이 유입될 수 있는 이동 허용공간을 갖게 상호 이격되어 상방으로 연장된 수직바를 갖는 프레임과, 상기 필름공급기로부터 공급된 신축 필름의 전단부가 개구되도록 상기 신축 필름을 각각 진공압에 의해 흡착된 상태에서 상호 이격되는 방향으로 이동되는 한 쌍의 석션패드와, 석션패드에 의해 개구된 신축 필름의 전단부를 파지하여 필름공급기에 의해 상단이 절단 및 접합처리된 신축필름을 주름 상태로 수용처리하고, 수직바를 하강하는 과정에서 신축필름이 물품에 씌어지도록 처리하는 복수개의 클램프를 구비하는 필름 클램핑부와, 필름클램핑부의 클램프가 신축 필름을 파지한 상태에서 수직바를 따라 하강되고 클램프가 신축 필름의 파지를 해제한 상태에서 수직바를 따라 상승되도록 필름클램핑부 및 필름공급부의 작동을 제어하는 제어부를 구비한다.
