摘要:
A bag manufacturing and packaging apparatus capable of reducing power consumption at the time of sealing while improving the sealing performance for sealing a film is provided. Sealing members 110 and 111 are each comprised of sealing jaws 110a and 111a that hold three surfaces of prismatic-shaped heaters 130 that are being embedded therein; and heat insulating members 110b and 111b that contact the other surface of the heaters 130. Sealing portions 112 and 113 for sealing are formed on the sealing jaws 110a and 111a. The sealing jaw 110a is connected to the heat insulating member 110b, and the sealing jaw 111a is connected to the heat insulating member 111b.
摘要:
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.

A form-fill-seal machine (1) has a forming structure, a vertical seal structure, and a clamp fixing mechanism (18). The forming structure has a support frame (33), a tube (31), a sailor collar-shaped unit (32), and an anvil (51). The tube (31) is fixed to the support frame (33). The sailor collar-shaped unit (32) is fixed to the support frame (33), and wraps a sheet-shaped film around the tube (31) so that two ends thereof overlap. The anvil (51) is fixed to the tube (31). The vertical seal structure has an oscillator (50). The oscillator (50) generates ultrasonic waves in order to seal overlapping portions of two ends of the film, being conveyed through the intervening gap with the anvil (51), in a vertical direction. The clamp fixing mechanism (18) fixes the forming structure and the vertical seal structure in fixed positions relative to one another.

An article transfer device is provided with a funnel-shaped structure and a high pressure air supply pipe. The funnel-shaped structure is provided with an upper end opening adapted to receive the articles being dropped in from above and a lower end opening adapted to allow the articles to drop through to the 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 plurality of 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.

A bag-making and packaging apparatus (1) includes a bag-making and packaging mechanism (5) and a fold formation mechanism (3). The fold formation mechanism (3) is configured and arranged to deform a packaging material (F) from a planar state to a folded state having a cross-sectional shape including a fold portion (FF) formed by three creases, and to feed the packaging material to the bag-making and packaging mechanism (5). The fold formation mechanism (3) may include a conveying path regulating part (31) that defines a part of a conveying path of the packaging material with the conveying path regulating part (31) temporarily bending the packaging material for a plurality of times. The bag-making and packaging apparatus may further include a slanting member (343) for slanting the fold portion (FF) to be generally parallel to a region of the packaging material other than the folding section, and a conveying angle changing member disposed downstream of the slanting member (343).

摘要:
In a packaging machine, a pair of shutter members holds a tubular film therebetween and shakes 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.
