A bag-making and packaging machine includes a bag-making and packaging section and a film supply section. The film supply section includes a film conveyance section that conveys a starting end portion of a replacement film roll supported by a film roll support portion to a bonding portion. The film conveyance section includes a clamping portion that holds a tape adhering to the starting end portion of the replacement film roll, and a pulling mechanism that pulls a second film held by the clamping portion from the replacement film roll. When the replacement film roll is mounted, the film roll support portion rotates the replacement film roll, and the clamping portion holds the tape of the replacement film roll rotated by the film roll support portion.

Bag-making and packaging machine

A bag-making and packaging machine includes sealing jaws, a horizontal moving device, a vertical moving device, and a control unit. The sealing jaws perform a transverse sealing operation. The vertical moving device moves the sealing jaws in a vertical direction. The vertical moving device includes a rotating shaft, a motor, and a link mechanism. The link mechanism transmits rotational force of the rotating shaft to the sealing jaws. The control unit performs first control or second control. The first control forwardly rotates and reversely rotates the rotating shaft during a period of time from a start of the transverse sealing operation to a start of a subsequent transverse sealing operation. The second control performs one of the transverse sealing operation and the subsequent transverse sealing operation with a forward rotation of the rotating shaft and the other with a reverse rotation of the rotating shaft.

A continuous bag-making and packaging apparatus is disclosed. In the apparatus, sealing is performed on a film at a predetermined position to make a bag while the film is continuously conveyed. The apparatus includes a film-conveying unit configured to change a feeding speed of the film, a printing unit configured to print on the film conveyed, a bag information acquisition unit configured to acquire information of a bag to be made, and a print timing presentation unit configured to present information pertaining to a print timing suitable for printing based on the information of the bag.

Continuous bag-making and packaging apparatus

A film roll supporting device comprises a shaft body part, a shaft tip part, and a projection part. The shaft body part extends through a central hole of a film roll and having the film roll mounted thereon. The shaft tip part extends in an axis direction of a shaft from one end of the shaft body part on a side to be inserted into the central hole of the film roll. The projection part extends in a direction intersecting the axis direction of the shaft body part from the shaft tip part. The projection part abuts from below to a core of the film roll provisionally placed on the shaft tip part when the mounting of the film roll is performed. A cutout recessed in a direction intersecting the axis direction of the shaft body part is formed in the projection part.
