  Further, the blade 31b of the die roll 31 has a plurality of quadrangular frames (four in the drawing) arranged in parallel in the axial direction in accordance with the outer shape of the package A, and projects in parallel in the circumferential direction, in other words, a lattice. It protrudes in a shape. The die roll 31 is also provided with bulging portions 31c that hold both side portions of the upper original fabric 202 at both ends of the roll body 31a.

  The four-side sealed package manufacturing apparatus of the first embodiment is configured as described above. Next, a method for manufacturing the package will be described.

  In this manufacturing apparatus, the lower original fabric 201 and the upper original fabric 202 sandwich the preparation 1 cut from the original preparation by the preparation supply means arranged on the upstream side. The lower original fabric 201 and the upper original fabric 202 are sandwiched one after another at intervals of a plurality of preparations 1 in the width direction (four in the drawing) and also in the length direction.

  Then, the sealing means 10 sandwiches the lower original fabric 201 and the upper original fabric 202 so as to continuously seal the four sides in the length direction so as to surround each preparation 1. In this embodiment, as shown in FIG. 5, the lower original fabric 201 and the upper original fabric 202 have a square shape (in the drawing, opposite to the square shape) with respect to the center line of the original fabric. The seals on the two sides face each other, and the portions to be the unsealing knobs 211 and 221 are provided between the seals on the two sides. Further, the center line and both side edges of the lower original fabric 201 and the upper original fabric 202 are also sealed.

  The lower original fabric 201 and the upper original fabric 202 that are sealed in this way are conveyed toward the half-cut means 20 on the downstream side of the sealing means 10. As shown in FIG. 6, the half-cut means 20 is configured so that one opening knob 221 provided adjacent to the width direction of the lower and upper original fabrics 201 and 202 is shorter than the other opening knob 211. Only the upper raw fabric 202 is punched at a position close to the preparation 1 side, and the punched narrow intermediate scrap 204 is removed as shown in FIG.

  The lower original fabric 201 and the upper original fabric 202 from which the intermediate scrap 204 has been removed are conveyed toward the full cut means 30 on the downstream side of the half cut means 20. As shown in FIG. 7, the full cut means 30 punches only the lower original fabric 201 at the portion where the intermediate scrap 204 has been removed, and the upper original fabric 202 and the lower original fabric 201 at other portions. The package A is manufactured. In FIG. 7, a large gap is drawn between each package A for easy viewing, but in reality, only a gap corresponding to the blade 31 b is left between each package A.

  As shown in FIG. 11, the package A is formed such that the upper opening knob 221 is shorter than the lower opening knob 221, and the corners are squared at right angles. Note that both side portions of the upper and lower raw fabrics 202 and 201 are removed as band-like ear scraps 203 as shown in FIG.

  Next, a second embodiment will be described with reference to FIGS. 2nd Embodiment manufactures the package A in which the corner as shown to Fig.12 (a) was formed in circular arc shape.

  In order to make the corners of the package A into an arc shape, the full cut means 30 for punching out the upper original fabric 202 and the lower original fabric 201 uses a die roll 31 in which the corners of the square frame-shaped blade 31b are arc shapes.

  As explained in the first embodiment, when the full cut means 30 punches the upper raw fabric 202 and the lower raw fabric 201 so as to form the arcuate corner of the package A with only the gap between the blades 31b, In a portion surrounded by four adjacent packages A, chip scraps of a substantially rectangular star shape are formed. However, since this chip scrap is a small piece, it is difficult to remove it, and it tends to remain attached to any package A.

  Therefore, in the four-side sealed package manufacturing apparatus of the second embodiment, a full cut means 30 as shown in FIG. 8 is used to manufacture the package A with arcuate corners without forming chip scrap. use. The full-cut means 30 has a space between a quadrangular frame-shaped blade 31b and a quadrangular frame-shaped blade 31b that are adjacent to each other in the axial direction, and the corners of each quadrangular frame-shaped blade 31b have an arc shape. ing.

  Also in the case of manufacturing the package A by punching out the upper original fabric 202 and the lower original fabric 201 with the full cut means 30 as described above, there are a plurality of packages A in the width direction (4 in the drawing). Sheet) of the preparation 1 from above and below between the upper original fabric 202 and the lower original fabric 201, as shown in FIG. 5, the periphery of the preparation 1 is sealed in four directions by the sealing means 10, and as shown in FIG. The upper raw fabric 202 on the side where the unsealing knob 221 is provided is punched out by the cutting means 20 and removed as intermediate scrap 204.

  The upper original fabric 202 and the lower original fabric 201 are conveyed to the downstream side of the half-cut means 20, and the full-cut means 30 is partially only for the lower original fabric 201, and the upper original fabric 202 is in another portion. And the lower raw fabric 201 is punched out. That is, the full cut means 30 is formed by punching only the lower original fabric 201 at the site where the upper original fabric 202 is removed as the intermediate scrap 204 by the half cut device 20 and the upper original fabric 202 at the site not removed as the intermediate scrap 204. The lower raw fabric 201 is punched out.

  And since the full cut means 30 has the space | interval between the blade 31b and the blade 31b which are adjacent in the axial direction, the package A and the package A which are manufactured adjacent in the axial direction. Intermediate scraps 204 (three in the drawing) are formed in between. The intermediate scrap 204 is formed with a protruding portion that bites into a deformed V-shape (a pair of arcs) at the boundary between the package A and the package A manufactured adjacent to each other in the length direction.

  Therefore, as shown in FIG. 9, the manufactured package A has a corner formed in an arc shape, and the chip scraps of small pieces are not attached to any of the packages A by the intermediate scrap 204. . Thus, in 2nd Embodiment, the package A as shown to Fig.12 (a) can be manufactured one after another.

  Next, a third embodiment will be described with reference to FIG. In the third embodiment, a package A in which a pair of unsealed knob portions 211 and 221 have the same length as shown in FIG. Therefore, in the third embodiment, the half-cut means 20 is not provided, and after the sealing means 10 as shown in FIG. 2 seals each formulation 1 in four directions, the full-cut means 30 as shown in FIG. By punching out the lower raw fabrics 202 and 201, the packages A are manufactured one after another as shown in FIG.

  The present invention can be variously modified without being limited to the first to third embodiments. For example, even if the pair of opening knobs 211 and 221 described in the third embodiment is the same length of the package A, the second cut-off means 30 shown in FIG. As described in the embodiment, the corner can be formed in an arc shape.

  Moreover, although the said embodiment demonstrated the case where the package A was manufactured 4 sheets at a time with respect to the width direction of the upper side original fabric 202 and the lower side original fabric 201, it becomes object with respect to the centerline of an original fabric. Needless to say, even numbers such as 6 or 8 can be manufactured, and odd numbers such as 3 or 5 may be manufactured.

  Further, by intermittently transporting the upper and lower raw fabrics 202 and 201, the sealing means 10 is provided with a frame-like protruding portion 11b that seals in four directions on the plate that moves up and down instead of the heat seal roller 11, and is half cut The means 20 and the full cut means 30 may be formed by projecting a frame-shaped blade 31b on a plate that moves up and down instead of the die roll 31.

  Moreover, the to-be-packaged product packaged in the package A is not limited to the preparation 1, and may be flat food or daily necessities. Moreover, even if the four-side sealed package is not a pentagonal shape but a four-sided sealed shape, it can be manufactured in the same manner as in the above embodiment by making the protruding portion 11b of the sealing means 10 into a rectangular shape. it can.
