る。[0007] Therefore, the pair of vertically long vertical heat welding opening / closing seal bars are provided between the vertical seal start position and the vertical seal end position.
Both side edges of the packaging film closed by the opening / closing means and folded in two along the longitudinal direction are vertically sealed over a length of one bag or more to form a tube, and the length of one bag is lengthened by the vertical moving means. Is conveyed over 1/2 of the distance. At the horizontal seal start position adjacent to the vertical seal end position, a pair of horizontal heat welding open / close seal bars are closed by the opening / closing means, and are horizontally sealed with the tubular packaging film therebetween to form a bottomed state and form an article to be packaged. While being filled via the chute, it is further conveyed by the vertical moving means to the end position of the horizontal seal over a distance of 1/2 the length of one bag. The open / close seal bars for vertical heat welding and horizontal heat welding are returned to the position where the sealing is started while the other is open by the opening / closing means and the vertical moving means for simultaneously opening and closing them in opposite directions and moving and driving. You. Therefore, unlike the conventional one in which the feeding is stopped during the vertical heat sealing, the feeding is performed while the vertical sealing is being performed, so that the speed can be increased, and the productivity is greatly improved. The vertical movement stroke of each open / close seal bar is also reduced to approximately half the length of one bag, so that the radial load on the heater power supply line can be reduced. The vertical welding means is moved up and down on each side of the gear that is reciprocated at a turning angle of, for example, 180 degrees. The power consumption for driving can be greatly reduced by balancing, and the load on the film can be reduced by moving the packaging film smoothly by the substantially continuous longitudinal movement of the packaging film.

ルムに対する負荷も軽減することが出来る。As is apparent from the above description, according to the seal bar type vertical automatic packaging machine according to the first aspect of the present invention, the pair of vertically elongated vertical heat welding opening / closing seal bars are positioned at the vertical seal starting position. To the vertical seal end position, the both side edges of the packaging film closed by the opening / closing means and folded in two along the longitudinal direction are vertically sealed over a length of one bag or more to form a tube and the vertical moving means Transport over a distance of 1/2 of the length of one bag. At the horizontal seal start position adjacent to the vertical seal end position, a pair of horizontal heat welding open / close seal bars are closed by the opening / closing means, and are horizontally sealed with the tubular packaging film therebetween to form a bottomed state and form an article to be packaged. While filling through the chute, the vertical moving means further moves to the end of the horizontal seal 1 / of the length of one bag.
Conveyed over a distance of 2. The open / close seal bars for vertical heat welding and horizontal heat welding are returned to the position where the sealing is started while the other is open by the opening / closing means and the vertical moving means for simultaneously opening and closing them in opposite directions and moving and driving. You. Therefore, unlike the conventional one in which the feeding is stopped during the vertical heat sealing, the feeding is performed while the vertical sealing is being performed, so that the speed can be increased, and the productivity is greatly improved. The vertical movement stroke of each open / close seal bar is also reduced to approximately half the length of one bag, so that the radial load on the heater power supply line can be reduced. The vertical welding means is moved up and down on each side of the gear that is reciprocated at a turning angle of, for example, 180 degrees. The power consumption for driving can be greatly reduced by balancing, and the load on the film can be reduced by moving the packaging film smoothly by the substantially continuous longitudinal movement of the packaging film.
