  • Bag making and packaging machine
    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.

  • Packaging apparatus
    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.

  • Bag-making and packaging machine
    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.

  • WEIGHING APPARATUS
    Publication number: 20210102833
    Abstract: [Problem] To provide a combination weighing apparatus that reduces power consumption during opening and closing operations of a hopper gate. [Solution] In a combination weighing apparatus 1, a control unit 70 controls a stepping motor 60 via a control signal that is input to the stepping motor 60. The control signal that is input to the stepping motor 60 is a voltage value corresponding to a desired current value. The control unit changes the control signal to the stepping motor 60 in conjunction with a change in the settings of the opening and closing speed of the gate 20. As a result, it becomes possible to supply power needed for the operation of the gate 20, and power can be saved.

  • Conveying device, and combination weighing apparatus having the conveying device
    Patent number: 10954075
    Abstract: The object of the present invention is to provide a novel conveying device with which it is possible to easily adjust a conveying amount of articles in a trough using a restricting plate, and a combination weighing apparatus having the conveying device. A conveying device to convey articles in a trough has a restricting plate to restrict a flow of the articles in the trough and the angle at which the restricting plate faces the articles is variable. With this configuration, there is no need to prepare a plurality of restricting plates that have different shapes and materials or to exchange such a plurality of restricting plates in the same manner as in a conventional device because the conveying amount in the trough can be adjusted merely by varying the angle at which the restricting plate faces the articles.
