20100210438 | BAG-MAKING PACKAGING MACHINE - A bag-making packaging machine includes a bag-producing part, a bag receiving part, and a bottom forming part. The bag-producing part is configured and arranged to transversely seal a tubular packaging material to produce a bag having a top seal part and a bottom seal part formed above and below a product-enclosing main body of the bag. The bag receiving part is configured and arranged to receive and hold the bottom seal part and a part of the main body of the bag, which has been dropped from the bag-producing part. The bottom-forming part is configured and arranged to deform the bag in contact with the bag receiving part to form a bottom portion of the bag into a prescribed shape. | 08-19-2010 |
20110131935 | FORM-FILL-SEAL MACHINE - A form-fill-seal machine is adapted to manufacture a bag having a gusset section, and includes a conveying part, a plurality of splitters and an inward-folding member. The conveying part is configured and arranged to convey a tubular packaging material. The splitters extend along a conveyance direction of the tubular packaging material to contact with the tubular packaging material from an interior side. The inward-folding member has a pressing part including a plurality of contacting portions that are three-dimensionally arranged to generally correspond to a shape of the gusset section. The inward-folding member is configured and arranged to press the contacting portions of the pressing part from an external side of the tubular packaging material against an outer surface of a gusset formation area of the tubular packaging material located between the splitters to form the gusset section. | 06-09-2011 |
20120204514 | PACKAGING MACHINE - A packaging machine includes a pair of brushes that hold a tubular film (Fm) therebetween while rotating and impeding the advancement of packaged articles. Consequently, an elongated stream of packaged articles aggregate at the leading end of the pair of brushes. When the pair of brushes release the tubular film, the packaged articles are again conveyed in a more closely aggregated state than the aggregated state thereof when the advancement of the packaged articles was temporarily impeded. The rotational axis of each brush is also biased a predetermined distance from the central axis of a core thereof. Since the brushes swing in conjunction with the rotation thereof, small vibrations and large swings cause the gaps between packaged articles to be readily filled and reduce the space occupied by the packaged articles. As a result, the bag size can be reduced. | 08-16-2012 |
20120204515 | PACKAGING MACHINE - In a packaging machine, a pair of shutter members holds a tubular film therebetween and shake the tubular film. Articles on an upstream side of the shutter members within the tubular film therefore aggregate toward the side of the shutter members while the vibration of the shutter members causes the gaps between the packaged articles to be filled. Since the packaged articles aggregate by inertia due to the vibration, fragmentation thereof is less likely than in a case in which the packaged articles are compressed by direct contact. Merely by the movement of rollers on a waved surface of a shutter cam, the shutter members are shaken in accordance with the waved surface. | 08-16-2012 |
20120204522 | ARTICLE TRANSFER DEVICE AND PACKAGING SYSTEM PROVIDED WITH SAME - An article transfer device includes a funnel-shaped structure and a high pressure air supply pipe. The funnel-shaped structure has an upper end opening adapted to receive articles dropped from above and a lower end opening adapted direct the articles to a form-fill-seal machine. An inner space is defined within the funnel-shaped structure between the openings. The upper part of the inner space has a greater cross-sectional area than the cross-sectional area of the lower part of the inner space. A plurality of air ejection holes are formed in an inner peripheral surface of the funnel-shaped structure surrounding the inner space. The air ejection holes are arranged with respect to one another defining a helical shape pattern about the funnel-shaped structure. Gaseous material is spouted out from the high pressure air supply pipe and into the inner space through the plurality of air ejection holes. | 08-16-2012 |
20120225763 | BAG-MAKING PACKAGING MACHINE - A bag-making packaging machine has a cylindrical part and a forming collar. The forming collar guides a sheet-shaped packaging material so that the packaging material wraps around the cylindrical part. The forming collar has a folded-back portion for changing a direction in which the packaging material advances to an approximately perpendicular direction. A cutout through which the thick-layered portion of the packaging material passes is formed in the folded-back portion. This reduces the amount of friction applied to the thick-layered portion when the packaging material passes by the folded-back portion of the forming collar. | 09-06-2012 |
20120285128 | FORM-FILL-SEAL MACHINE - A form-fill-seal machine has a tube, a sailor-collar-shaped part, and a vertical sealing mechanism. The sailor-collar-shaped part wraps a sheet-shaped film around the tube so that two edges thereof define overlapping portions. The vertical sealing mechanism ultrasonically seals the overlapping portions of the sheet-shaped film in the vertical direction. The vertical sealing mechanism has an oscillator and a roller. The oscillator generates ultrasonic waves. The roller is disposed downstream of the oscillator along the advancing direction of the film. The roller holds down the film while rotating in the advancing direction of the film after the film has passed the oscillator. | 11-15-2012 |
20130059709 | BAG MAKING AND PACKAGING MACHINE - A bag making and packaging machine forms a first transverse seal portion in a packaging material formed in a tubular shape, fills the packaging material with articles, thereafter further forms a second transverse seal portion to make a bag, and allows the bag to fall, and is equipped with a vibrating mechanism. The first transverse seal portion is formed in a direction perpendicular to a conveyance direction of the packaging material. The vibrating mechanism tilts the packaging material to an outer side of a fall path of the bag and vibrates the packaging material after the packaging material has been filled with the articles and before the second transverse seal portion is formed. | 03-07-2013 |
