Bag-making and packaging machine

A bagmaking and packaging device includes a transverse sealing unit, a first tube member, and a gas flow path member. The first tube member is disposed above the transverse sealing unit and extends in an up and down direction. The first tube member allows a packaging material to become wrapped around it to thereby form the packaging material into a tubular shape. At least part of the gas flow path member is disposed inside the first tube member. The gas flow path member delivers nitrogen into the packaging material formed into the tubular shape. The first tube member includes a cutout portion that extends in the up and down direction. The cutout portion is formed so that the nitrogen can move between a space between the packaging material formed into the tubular shape and the first tube member and the inside space of the first tube member.

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 bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.

Bag-making and packaging apparatus

A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit.

A form-fill-seal machine is configured to adjust for changes in the thickness of bags within a short time, and is provided with seal jaws, gas removal members, an air cylinder, and a control unit. The seal jaws transverse-seal a cylindrical film in a widthwise direction forming a bag. The gas removal members come into contact against the bag prior to transverse sealing of an upper edge part, discharging a gas upward from the bag. The air cylinder moves the gas removal members, switching the position of the gas removal members between a first position and a second position with respect to the seal jaws. The control unit, in a time slot just prior to the start of a transverse sealing action performed by the seal jaws, changes the timing of switching between the first position and the second position, and adjusts the amount of gas discharged from the bag.
