Abstract
A suction control apparatus is adapted to be used in a packaging machine for conveying and packaging a belt-shaped film while the film is being suctioned by a suction-type film conveyor. The suction control apparatus includes a proper vacuum-degree determination section and a vacuum-degree control unit. The proper vacuum-degree determination section is configured and arranged to determine a proper degree of vacuum of the suction-type film conveyor, which is less than a reference value set in advance. The vacuum-degree control unit is configured to set the degree of vacuum to a first value corresponding to the proper degree of vacuum determined by the proper vacuum-degree determination section.
Claims8
A suction control apparatus adapted to be used in a packaging machine for conveying and packaging a belt-shaped film while the film is being suctioned by a suction-type film conveyor, the suction control apparatus comprising:
- an air intake box with an air intake opening;
- a conveying belt arranged adjacent to the air intake box, the conveying belt having plurality of air intake holes;
- a vacuum-degree determination section configured and arranged to determine a proper degree of vacuum of the suction-type film conveyor, which is less than a reference value set in advance, such that the film is drawn toward the conveying belt in response to the proper degree of vacuum being applied to the air intake box;
- and
- a vacuum-degree control section configured to set the degree of vacuum to a first value corresponding to the proper degree of vacuum determined by the proper vacuum-degree determination section.
A suction control apparatus adapted to be used in a packaging machine for conveying and packaging a belt-shaped film while the film is being suctioned by a suction-type film conveyor, the suction control apparatus comprising:
- a conveying state detection section configured and arranged to detect a speed at which the film is conveyed or a conveying time required for a predetermined length of the film to be conveyed;
- a storage section configured and arranged to store a set speed value for the conveying speed or a set time value for the conveying time;
- a vacuum-degree determination section configured and arranged to determine a proper degree of vacuum of the suction-type film conveyor, which is less than a reference value set in advance, such that the film is drawn toward the conveying belt in response to the proper degree of vacuum being applied to the film;
- and
- a vacuum-degree control section configured to set the degree of vacuum to a first value corresponding to the proper degree of vacuum determined by the vacuum-degree determination section, the vacuum-degree control section being further configured to adjust the degree of vacuum so that the conveying speed falls within a predetermined range with respect to the set speed value, or so that the conveying time falls within a predetermined range with respect to the set conveying time value.
