Abstract: 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.

Abstract: A bag-making and packaging machine forms a sheet-like film into a tubular shape and transversely seals the film to manufacture bags containing articles. The bag-making and packaging machine includes a transverse sealing mechanism and a control unit. The transverse sealing mechanism pinches and transversely seals the tubular film that has been formed into a tubular shape to form a transverse seal portion. The control unit determines whether or not there is jamming in the transverse seal portion and, in a case where it has determined that there is jamming, switches between a first bag-making process to continue bag-making operation and a second bag-making process to stop bag-making operation based on a jamming state.

Abstract: A bag-making and packaging machine includes a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film roll holding unit that rotatably holds a first film roll, a film temporary placement member on which a vicinity of a leading end portion of a first film wound into the first film roll is manually temporarily placed when attaching the first film roll to the film roll holding unit, a leading end portion detection sensor configured to detect that the leading end portion of the first film is positioned in a prescribed position, and a controller configured to control a rotating mechanism to convey the first film along a predetermined conveyance path until the leading end portion detection sensor detects that the leading end portion of the first film is positioned in the prescribed position.

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 holding mechanisms each having a shaft that holds a film roll, a holding mechanism support frame supporting the holding mechanisms, a moving mechanism that rotates the holding mechanism support frame to move each holding mechanism between a film roll setting position and a film supply position, a splicing mechanism splicing a trailing end portion of the film of the roll of one of the holding mechanisms and a leading end portion of the film of the roll of another one of the holding mechanisms, and a film drawing mechanism that rotates the shafts of the holding mechanisms to draw the film independently from the film rolls attached to the shafts of the holding mechanisms and changes the drawing speed of the film during bag-making and packaging.

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.

Abstract: 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.

Abstract: Certain implementations provide a form-fill-seal machine that can efficiently seal a packaging material. The transverse sealing unit may have first members to sandwich the packaging material and sealing the packaging material in a transverse direction, and second members for squeezing the packaging material while sandwiching the packaging material with a prescribed gap left therebetween. The control unit may cause the packaging material to be squeezed by the second members by causing the transverse sealing unit located at a reference position to descend faster than the packaging material being conveyed downward. The control unit may cause the transverse sealing unit to ascend while the packaging material is being sealed by the first members. The control unit may cause the transverse sealing unit to move such that the first members are separated from the packaging material.
