Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seal cutting device for a continuous package that cuts a horizontal seal that divides a storage section for storing powdery or liquid soup, for example.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as a device for cutting a seal portion of a continuous package of this type, there is a device shown in FIG. The conventional sealing part cutting device is incorporated in a so-called pouch dispenser, which is provided on both sides of a continuous package P conveyed along a conveying path α extending vertically upward and downward. An upper cutter blade driving unit 3 and a lower cutter blade driving unit 4 are disposed on the lower surface side of a base plate 2 fixed to a mounting plate 1 in a dispenser so as to face each other. Reference numerals 5 and 5 are feed rollers for transporting the continuous package P 2.

[0003] The continuous package P is configured such that storage sections 6 for storing the articles to be packaged are sectioned and connected along a transport path α, and a horizontal seal section 7 formed by a heat seal substantially orthogonal to the transport path α. Are formed at a required interval from each other, and a vertical seal portion 8 also formed by heat sealing is continuously formed along one of the side edges P 'and P ".

The upper cutter blade driving unit 3 slidably attaches a slider 10 to a slide guide 9 attached to the lower surface of the base plate 2, and attaches an upper cutter blade 12 to the slider 10 via a cutter blade holder 11. It is made to hold.

The lower cutter blade driving unit 4 slidably attaches a slider 10 ′ to a slide guide 9 ′ attached to the lower surface of the base plate 2, and a cutter 10 ′ to the slider 10 ′ via a cutter blade holder 13. The lower cutter blade 14 is held. In the seal cutting device having the above-described configuration, the upper seal blade 12 and the lower cutter blade 14 are driven to advance and retreat horizontally with respect to the continuous package P, so that each of the horizontal seal portions 7 of the continuous package P is formed. Is disconnected.

Meanwhile, since the vertical and horizontal seal portions 8 and 7 of the continuous package P are formed by performing so-called heat sealing, the base material is smaller than before forming the respective seal portions. Tends to stretch. In particular, when one side edge portion P 'on which the vertical seal portion 8 is formed is extended, as shown in FIG. 7, the continuous package P is bent and deformed toward the other side edge portion. It will be transported in the shifted state.

However, in the above-described conventional apparatus, the upper and lower cutter blades 12 and 14 for cutting the horizontal seal portion 7 are directly opposed to the horizontal seal portion 7 in accordance with the shift of the horizontal seal portion 7. Since the horizontal seal portion 7 cannot be inclined vertically, it cannot be cut up and down at the center of the horizontal seal portion 7, thereby deteriorating the commercial value.

Conventionally, as shown in FIG. 8, the conveying posture of the continuous package P is set so that the horizontal seal portion 7 conveyed between the upper and lower cutter blades 12 and 14 is horizontal. Or the upper cutter blade drive unit 3 and the lower cutter blade drive unit 4 are tilted in advance in accordance with the curved deformation of the continuous package P. It is supported by installing.
