BEST MODE FOR CARRYING OUT THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

  1 to 8 are views showing a first embodiment of a cut label discharging system according to the present invention.

  First, referring to FIG. 1 and FIG. 2, for example, the entire blank manufacturing system for manufacturing a printed sheet-fed blank for producing a paper container or the like will be described.

  As shown in FIGS. 1 and 2, the blank manufacturing system 10 incorporates a cut label discharge system 20A according to the present invention. Such a blank manufacturing system 10 winds up a printed elongated web 1 (see FIGS. 3A, 3B, and 3C) having a defect display label 2 for displaying a print defect on one side edge. A web feed unit 11A for continuously feeding the web 1 from the wound body 11, a web feed line 12 for feeding the web 1 unwound from the paper feed unit 11A, and a downstream side of the web feed line 12. A longitudinal cutter 20 that cuts both side edges of the web 1 in the longitudinal direction to generate a cut web 1c (see FIG. 4), and is provided downstream of the longitudinal cutter 20 via a web conveyance line 12A. And a widthwise cutter 13 for producing a printed sheet-fed blank 3 by cutting the web 1 having the edge cut in the widthwise direction. The web 1 is transported in the horizontal direction, and the transport speed is 80 to 200 m / min.

  The printed sheet-like blank 3 obtained by cutting the web 1 in the width direction by the width-direction cutter 13 is then sent to the blank transport unit 14, and the printed sheet-like blank 3 is then sent from the blank transport unit 14. Transferred to the blank discharge unit 15. The printed sheet-fed blank 3 transferred to the blank discharge unit 15 is then fed into the blank stacking unit 16 by the blank discharge unit 15 and stacked in the blank stacking unit 16.

  The printed sheet-fed blank 3 accumulated in the blank accumulating unit 16 is then sent to a subsequent process, punched into a blank for each product, and used as a paper container.

  Of the above components, the longitudinal cutter 20 and a label guide mechanism 23A described later constitute a cut label discharge system 20A according to the present invention.

  Note that the wound body 11 disposed in the paper feeding unit 11A winds the printed elongated web 1 and displays a printing defect on one side edge of the web 1 to identify the defective portion. The defect display label 2 is affixed.

  Next, the defect display label 2 affixed to one side edge of the web 1 will be described with reference to FIGS. As shown in FIGS. 3A, 3B, and 3C, the defect display label 2 has an adhesive region 2a having a length of 25 mm bonded to the web 1 and a non-adhesive region 2b having a length of 15 mm that is not bonded. The overall length is 40 mm and the width is 25 mm. Moreover, the adhesive is apply | coated to the adhesion | attachment area | region 2a. Of these, the bonded region 2a side is bonded to the web 1, and the non-bonded region 2b protrudes outward from the side edge of the web 1 by 10 mm.

  The defect display label 2 displays a defect such as a print defect or a defect of the web 1, for example. In a later process, the printed sheet blank 3 with the defect display label 2 affixed to the outside as a defective product. Is discharged.

  As will be described later, the defect display label 2 is cut by the longitudinal cutter 20 to generate a cut label 2c. However, as shown in FIG. 4, the defect display label 2d remaining on the cut label 2c and the sheet blank 3 is provided. A common identification number n may be attached to both. In this way, in the subsequent process, it is possible to confirm whether the defective product is discharged by matching the recognition number of the defect display label 2d attached to the defective sheet blank 3 and the recognition number of the cut label 2c. Therefore, it is possible to reliably prevent a defective product from flowing out as a non-defective product.

  As described above, in the longitudinal cutter 20, both side edges of the web 1 are cut in the longitudinal direction to generate the cut web 1c. The cut web 1c generated by cutting the web 1 with the longitudinal cutter 20 is then guided and accumulated in the accumulating section 25 installed below the conveying line 12A of the web 1. When both side edges of the web 1 are cut in the longitudinal direction by the cutter 20, the defect display label 2 is also cut at the same time to generate a cut label 2c.

  In this case, since both sides of the web 1 are cut about 2 to 5 mm from the end so that the adhesive of the defect display label 2 does not adhere to the longitudinal cutter 20, the cut label 2c is not bonded. It consists of only the region 2b, and the bonded region 2a is not cut, but of course it is not limited to this, and the cut label 2c may include the non-bonded contact region 2b and the bonded region 2a.

  Next, the longitudinal cutter 20 will be described with reference to FIGS. As shown in FIGS. 4 to 8, the longitudinal cutter 20 has a side edge of the web 1 between the circular lower blade 21 and the lower blade 21 in a side view provided on each side edge of the web 1. It has a circular upper blade 22 in a side view to be cut.

  In this case, each side edge of the web 1 is cut between the corresponding inner edge 21 a of the lower blade 21 and the upper blade 22.

  Each of the lower blades 21 has a circumferential surface 21b, and a cutting label 2c is provided between the lower blade 21 and the circumferential surface 21b on the lower blade 21 that cuts the side edge on which the defect display label 2 is attached. A guide roller 23 is provided for clamping.

  As shown in FIGS. 7A and 7B, a plurality of, for example, three guide rollers 23 sandwiching the cutting label 2 c between the lower blade 21 and the circumferential surface 21 b are arranged on the lower blade 21. Along the surface 21b, the lower blade 21 and the web 1 are provided downstream from the installation surface. Note that at least two guide rollers 23 are provided. In this case, each guide roller 23 has a diameter of 20 mm and a width of 6 mm. The distance D1 between the guide rollers 23 in the horizontal direction is 20 mm in the distance between the centers, and the most upstream guide roller 23 and the most downstream side. A distance D2 between the guide rollers 23 in the height direction of the guide roller 23 is 8.5 mm as a distance between the centers.

  On the other hand, since the length of the cutting label 2c in the discharge direction is 25 mm, the cutting label 2c can be securely held and guided by the three guide rollers 23. That is, the cut label 2c is transported downward along the lower blade 21, and is discharged from the most downstream guide roller 23. Therefore, the cut label 2c is discharged at a position away from the transport line 12A of the web 1. Thus, it is possible to prevent the cut label 2c from being mixed into the web of the next process or the cut label from adhering to a printed blank as a product. If the cut label 2c can be transported in a direction different from the transport direction of the web 1, the lower blade 21 may not be circular in a side view. Furthermore, the effect of this invention can be improved by narrowing the space | interval D1 between the guide rollers 23 in a horizontal direction rather than the length of the discharge direction of the cutting label 2c. Moreover, when the conveyance speed of the web 1 is set to 80 to 200 m / min, the cut label 2c is easily pulled in the conveyance direction of the web 1, and thus the cut label discharge system of the present embodiment is suitable.

  When both side edges of the web 1 are cut along the longitudinal direction between the lower blade 21 and the upper blade 22 of the longitudinal cutter 20, the cut web 1c is generated from the web 1 and the cut label 2c is cut from the defect indication label 2. Is also generated.

  The cut web 1c generated in this way is continuously guided into the accumulating section 25, but the cut label 2c is peeled off from the cut web 1c and scattered into the web 1 in the next process to become a product. It is also possible to adhere to the printed blank 3.

  In the present embodiment, in order to prevent scattering of the cut label 2c, the cut label 2c is held between the circumferential surface 21b of the lower blade 21 and the three guide rollers 23, and the cut web 1c is held. . Then, the cutting label 2c is sandwiched between the circumferential surface 21c of the lower blade 21 and the guide roller 23, and the cutting label 2c is guided to a position away from the conveying line 12A of the web 1, whereby the cutting label 2c is scattered. It can prevent in advance that it mixes in the web 1 of the next process. At this time, the cut label 2c may be guided into the stacking section (cut label stacking section) 25 by sucking with a vacuum or the like. If it does in this way, the operation | work which matches the recognition number of the defect display label 2d stuck on the defective sheet | seat-shaped blank 3 and the recognition number of the cutting label 2c can be made easy. Alternatively, the cut label 2c may be guided to a stacking unit (not shown) different from the stacking unit 25 by sucking with vacuum or the like. In this case, since only the cut label 2c exists in another stacking unit, the operation of matching the recognition number of the defect display label 2d attached to the defective sheet blank 3 with the recognition number of the cut label 2c is further performed. Can make it easier.

  Thus, the circumferential surface 21b of the lower blade 21 that sandwiches the cut label 2c generated in the longitudinal cutter 20 and the guide roller 23 constitute a label guide mechanism 23A that guides and discharges the cut label 2c. In this case, the cutting label 2c is sandwiched between the lower blade 21 and the guide roller 23, the lower blade 21 becomes a nip roller (one nip roller) on the lower surface side of the cutting label 2c, and the guide roller 23 is an upper surface of the cutting label 2c. This is the nip roller on the side (nip roller on the other side). The cut label discharging system 20A according to the present invention includes the longitudinal cutter 20 and the label guide mechanism 23A as described above.

  Next, the operation of the present embodiment having such a configuration will be described.

  In this case, as the web 1, a paper web or a laminate web including a paper layer is used, but a plastic web may be used.

  The web 1 unwound from the paper supply unit 11A is then conveyed by a web supply line 12, and the web 1 reaches a longitudinal cutter 20 provided on the downstream side of the web supply line 12, and the longitudinal cutter 20 In FIG. 4, both side edges of the web 1 are cut in the longitudinal direction to generate a cut web 1c (see FIG. 4).

  Next, the web 1 with both side edges cut reaches the width direction cutter 13 provided on the downstream side of the longitudinal direction cutter 20 via the web conveyance line 12A, and the web 1 is cut in the width direction by the width direction cutter 13. Thus, a printed sheet-fed blank 3 is obtained.

  The printed sheet-like blank 3 obtained by cutting the web 1 in the width direction by the width-direction cutter 13 is then sent to the blank transport unit 14, and the printed sheet-like blank 3 is then sent from the blank transport unit 14. Transferred to the blank discharge unit 15. The printed sheet-fed blank 3 transferred to the blank discharge unit 15 is then fed into the blank stacking unit 16 by the blank discharge unit 15 and stacked in the blank stacking unit 16.

  The printed sheet-fed blank 3 accumulated in the blank accumulating unit 16 is then sent to a subsequent process, punched into a blank for each product, and used as a paper container.

  Meanwhile, as shown in FIGS. 4 and 5, in the longitudinal cutter 20, both side edges of the web 1 are cut in the longitudinal direction to generate a cut web 1 c. Guided and accumulated. Further, when both side edges of the web 1 are cut in the longitudinal direction by the longitudinal cutter 20, the defect display label 2 is also cut at the same time to generate a cut label 2c.

At this time, the cut label 2c may also be guided into the stacking unit (cutting label stacking unit) 25. Alternatively, the cut label 2c may be guided to a stacking unit different from the stacking unit 25.

  Next, the operation of the longitudinal cutter 20 will be described in detail with reference to FIGS. First, as shown in FIGS. 7A and 7B, when the web 1 reaches the longitudinal cutter 20, both side edges of the web 1 extend in the longitudinal direction between the lower blade 21 and the upper blade 22 of the longitudinal cutter 20. The cut web 1c is generated by being cut, and the cut web 1c is sandwiched between the circumferential surface 21b of the lower blade 21 and the guide roller 23 and led into the stacking portion 25.

  Next, as shown in FIGS. 8 (a) and 8 (b), when the defect display label 2 affixed to the web 1 reaches the longitudinal cutter 20, the defect display label 2 together with the side edges of the web 1 are the lower blade 21 and the upper blade. The cut label 2c and the cut web 1c are generated at the same time.

  The cut label 2 c is sandwiched between the circumferential surface 21 b of the lower blade 21 and the guide roller 23 and is discharged to a position away from the conveyance line 12 A of the web 1.

  As described above, according to the present embodiment, the cutting label 2 c generated by cutting the web 1 and the defect display label 2 in the longitudinal direction in the longitudinal cutter 20 is used as the circumference of the lower blade 21 of the longitudinal cutter 20. The cutting label 2c can be guided by being sandwiched between the surface 21b and the guide roller 23 and guided to a position away from the conveying line 12A of the web 1. For this reason, the cut label 2c generated in the longitudinal cutter 20 is not scattered and mixed into the web 1 of the next process, and the cut label does not adhere as a foreign matter to the print blank 3 as a product.
