  • Patent number: 11136155
    Abstract: A bag-making and packaging machine packages, in bags made from a film, articles discharged and dropped from an article discharge apparatus. The bag-making and packaging machine has a transverse sealing mechanism, a receiving member, a vertical moving mechanism, and a control unit. The transverse sealing mechanism transversely seals a film tube. The receiving member contacts an outer surface of the film tube above the transverse sealing mechanism and receives the articles A that drop through the inside of the film tube. The vertical moving mechanism moves the transverse sealing mechanism and the receiving member in the up and down direction. The control unit switches between a first mode and a second mode. In the second mode, the receiving member contacts the outer surface of the film tube at a lower height position than in the first mode.

  • Patent number: 11052628
    Abstract: A bag making and packaging machine has pull-down belt mechanisms, a transverse sealing mechanism, a rotatable folding member, and a gas blowing mechanism. The folding member, before the transverse sealing mechanism, seals a cylindrical film, pushes against a side portion of the cylindrical film to thereby fold the cylindrical film inward and form a fold in the cylindrical film. The gas blowing mechanism blows a gas onto the fold to thereby inhibit the cylindrical film from sticking to the rotating folding member.

  • Patent number: 11046468
    Abstract: A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.

  • Patent number: 11046467
    Abstract: A packaging apparatus includes a controller configured to control operation of a first conveying unit, a second conveying unit, a first moving unit, and a second moving unit. When a film is loaded onto the first conveying unit and the second conveying unit, the controller causes a first clamp unit to clamp the film delivered from a delivering unit and causes a first feeder portion to convey the film. Simultaneously, while causing a second clamp unit to be released or the second clamp unit to intermittently clamp the film delivered from the delivering unit, the controller causes a second feeder portion to convey the film and also causes the second conveying unit to move in a direction separating from the first conveying unit and, when the second conveying unit reaches a predetermined position, causes the second clamp unit to clamp the film.
