A system for determining an amount of stretch film unwound from a stretch film dispensing apparatus. The stretch film dispensing apparatus includes a roller, from which the stretch film can be unwound, at least one supply roll sensor positioned relative to the roller to sense a distance from the at least one supply roll sensor to an outside face of a supply roll on a core on the roller, and a controller. The controller is configured to determine the amount of stretch film unwound based on the one or more signals provided by the at least one supply roll sensor.

Medicine packaging apparatuses and methods for accurately determining a remaining sheet amount of a medicine packaging sheet are described. The apparatus includes: a roll support section to which a core tube of a medicine packaging sheet roll is attached; a sensor disposed in the roll support section for outputting a count value according to a rotation amount; a wireless reader-writer unit for writing information to a core tube IC tag and reading said information; an information generation section for generating information to be written to the core tube IC tag; a remaining sheet amount estimation section for estimating a current amount of remaining sheet based on the information and dimensional information of the core tube; and a controller which selectively performs an operation if a reference time-point count value is not yet written to the core tube IC tag and another operation if the count value is already written thereto.

A method and an arrangement for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll is adapted for use with. a tissue dispenser for dispensing portions of the continuous web of tissue from the tissue roll. The method comprises the steps of counting portions of the tissue dispensed by the tissue dispenser, determining an initial filling level depending on the counter data and an initial tissue type information, and determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred.

A sheet binding device includes a sheet shifting unit, a tape cutter, and a tape attachment unit. The sheet shifting unit has a guide and is configured to stack multiple sheets on the guide with edge portions that are shifted from each other to form a sheet bundle. The tape cutter cuts tape with a target length that is varied in accordance with a thickness of the sheet bundle. The tape attachment unit is configured to attach the cut tape having the target length to an edge portion of the sheet bundle.

A winding condition generating apparatus includes: an input unit; an output unit; and a condition calculation unit. A winding condition calculation unit includes a learning model created by machine learning using a combination of a winding parameter and a winding condition in producing a wound web that satisfies a target winding quality as training data, and calculates a winding condition of a new wound web using the learning model, from a winding parameter of a new wound web input through the input unit. The output unit outputs the winding condition. The winding parameter includes a web width, a web transport velocity, and a web winding length. The winding condition includes a tension of the web at the start of winding and a tension of the web at the end of winding.

Provided is a bag making and packaging machine having superior workability in film joining work. A bag making and packaging machine is a bag making and packaging machine that uses film having at least one character or a figure printed on its front side, and is equipped with a film roll support unit, a conveyance unit, a bag making unit, and a light emitting component. The film roll support unit supports a film roll in which the film is wound in a roll. The bag making unit processes the film to make bags. The conveyance unit is positioned between the film roll support unit and the bag making unit. The conveyance unit feeds the film to the bag making unit. The light emitting component illuminates, from the direction of the front side of the film, the film positioned between the film roll support unit and the conveyance unit.
