Definitions

  • the present invention relates to a corrugated-paperboard box wherein flute restoring force which is induced around a main crease, is reduced and thereby a bulging phenomenon does not occur in the corrugated-paperboardbox and dimensional stability is enhanced, and more particularly, the present invention relates to an apparatus and a method for producing a corrugated-paperboard box, wherein a plurality of preliminary creases or fold lines which have gradually decreasing widths and gradually increasing depths, are overlappingly formed in a multi-stepwise manner along a linear region where a corrugated-paperboard box blank is to be folded, in the course of feeding a corrugated paperboard by feeding means, which is printed with a predetermined pattern, whereby a cause of dimensional unstableness which can be generated by a cumulative error due to folding position deviations upon folding the corrugated-paperboard box blank, is eliminated, and productivity is improved and high value added is accomplished.
  • packing boxes are divided into paper boxes and corrugated-paperboard boxes.
  • a paper box is produced using a single paperboard which has a certain stiffness.
  • the paper boxes are used for packing goods such as clothes, confectionaries or the like, which are free from shocks applied thereto from the outside.
  • a corrugated-paperboard box is produced in such a manner that at least one corrugated medium which has a shock-absorbing property, is intervened between a pair of liners, thereby to secure a shock-absorbing space between the pair of liners.
  • the corrugated-paperboardboxes are used for safely protecting packed articles from shocks which are applied thereto from the outside while the articles are transported or stored.
  • Such corrugated-paperboard boxes can be produced using a double-faced single-medium corrugated paperboard or a double-faced double-medium corrugated paperboard, depending upon a kind of an article to be packed.
  • a double-faced double-medium corrugated paperboard as the corrugated paperboard which is wound around a roll, is fed, an outer surface of a first liner which is adhesively laminated on a first corrugated medium having a dense flute structure, is printed with a predetermined pattern.
  • the corrugated paperboard 10 which is printed with the predetermined pattern is guided between an upper feeding roll 22 and lower feeding means 26.

  • a multicolored printing pattern is formed on the corrugated paperboard 10. Then, a creasing and slotting process for forming at least one crease or folding line and at least one slot is performed, thereby to define a linear folding region on an outer surface of a second liner which is adhesively laminated on a second corrugated medium having a sparse flute structure. Thereafter, a resultant corrugated-paperboard box blank is supplied to a folding guider (not shown), to experience a folding process for folding the corrugated-paperboard box blank along the linear folding region. Next, by implementing a gluing process for gluing both ends of the corrugated-paperboard box blank to each other, a desired corrugated-paperboard box is accomplished.
  • the conventional apparatus for producing a corrugated-paperboard box suffers from defects in that, when the corrugated paperboard 10 printed with the predetermined pattern is fed, only the upper feeding roll 22 shaped in the form of a cylindrical column and the lower feeding means 26 including the plurality of feeding rolls 24 which guide the corrugated paperboard 10 to the subsequent process in a state wherein they elastically support the printed surface of the corrugated paperboard 10, are used. Therefore, the upper feeding roll 22 and the lower feeding means 26 merely feed the corrugated paperboard 10 on a plane. Moreover, because only some portions (three portions in FIG.

That is to say, in order to fold a corrugated paperboard 10 along preset positions depending upon a size of a corrugated-paperboard box to be produced, creases or folding lines are formed at the preset positions. These preset positions are designated by points A, B and C in FIG. 2 for ease of reference.
  • an inner corrugated medium 13 is sandwiched between an inner liner 11 and an intermediate liner 12, and an outer corrugated medium 15 is sandwiched between the intermediate liner 12 and an outer liner 14 an outer surface of which is printed with a predetermined pattern.
  • the inner corrugated medium 13 which has a large pitch and a large flute height, reveals superior foldability to the outer corrugated medium 15 which has a small pitch and a small flute height. Therefore, the corrugated paperboard 10 is folded downward at the points A, B and C in a manner such that each folded portion of the corrugated paperboard 10 defines a V-shaped contour rather than a 180°-rotated V-shaped contour.
  • a folding position deviation of dl is engendered, thereby inducing final mismatch between both ends of a corrugated-paperboard box blank as shown in FIG. 3a.
  • This folding position deviation dl is represented by a distance between the point A and an actual folding point which corresponds to a position of a valley portion, nearest to the point A, of the inner corrugated medium 13.
