Definitions

  • the present invention relates to a double facer that is available in a heating part of a double facer system within a corrugate machine.
  • FIG. 10 A general construction of the heretofore known double facer system is illustrated in Fig. 10, and de­tailed structures of a weight roll section in the double facer system in the prior art and problems involved in these structures are shown in Figs. 5 to 9.
  • a double facer system in a corrugate machine is constituted of a heating part 10 and a cooling part 15, and this is a system for manufac­turing various kinds of double-faced corrugated cardboard sheet 3 by sticking a single-faced corrugated cardboard sheet 1 produced by a single facer in the preceding stage and a liner 2 to each other.
  • the above-mentioned heating part 10 is composed of a preheater section 16, a heating box (hot plate) section 13, a canvas belt section 14, a pressing section 17 and the like
  • the cooling part 15 is composed of a conveyor belt section 18, a canvas belt section 14, a pressing section 19 and the like.
  • a single-­faced corrugated cardboard sheet 1 produced by the single facer in the preceding stage has starch paste 24 applied to crests 20 of its corrugations in a glue machine 20, and then it is conveyed into the heating part 10 of the double facer system.
  • the liner 2 is preheated by the preheater 16, and is likewise conveyed into the heating part 10 of the double facer system.
  • the starch paste 24 is solidified, hence the single-faced cardboard sheet 1 and the liner 2 are sticked to each other, and a double-­faced corrugated cardboard sheet 3 is formed.
  • the weight rolls 23 of the double facer in the prior art are constructed as shown in Figs. 5 to 7, in which an integral type weight roll 23 having such length that it can press the corrugated cardboard sheet over the entire width is pivotably secured to one ends of a pair of arms 26 via bearings provided at its opposite ends, and the other ends of the same arms 26 are pivotably secured to a fulcrum shaft 9 via bushes or bearings 8.
  • the oppo­site ends of the fulcrum shaft 9 are fixedly secured to frames 30 positioned on the opposite sides of the heating part 10.
  • the weight rolls 23 each of which is constructed as described above, are disposed as arrayed in the travel­ing direction of the corrugated cardboard sheet 3.
  • the weight roll 23 cannot make the deformation along the concaved surface of the hot plate, although it flexes to a certain extent due to its own weight. Accordingly, the pressing force exerted by the weight roll 23 would become uneven along the widthwise direction of the machine. In other words, there occurs a tendency that pressing forces at the opposite end por­tions become large as compared to the pressing force at the central portion of the machine.
  • the prior art double facer system involved the problems that loss sheets were produced due to poor sticking caused by the uneven pressing and it was difficult to insure the quality of the produced corrugated cardboard sheet.
  • the above-featured double facer in which weight roll rows in each of which a plu­rality of weight rolls are aligned in the widthwise direc­tion of the corrugated cardboard sheet, are disposed in multiple as arrayed in the direction of traveling of the corrugated cardboard sheet, and the weight rolls in the adjacent rows are disposed in a staggered relationship so as to form a checker pattern.
  • each weight roll in the prior art is divided into a plurality of minor weight rolls along the axial direction of the weight roll and the respective minor weight rolls are respectively swingable independently of each other, is employed, always uniform pressing forces can be obtained regardless of deformation of the heating box, hence it becomes possible to make heat and tension applied to the corrugated cardboard sheet uniform along the widthwise direction, and so manufacture of a corrugated cardboard sheet of excellent quality becomes possible.
  • uniform pressing forces over the sheet traveling direction of the corrugate machine can be applied to the double-faced corrugated cardboard sheet.
  • a double facer in a corrugate machine that is, with regard to a series of working steps and a schematic construction of an apparatus for manufacturing a double-faced corrugated cardboard sheet 3 by sticking a single-faced corrugated cardboard sheet 1 produced by a single-facer in the preceding step and a liner 2 carried in through a separate route, it is quite similar to that described above in connection to the prior art.
  • the weight rolls 4 shown in Figs. 1 to 3 respec­tively have a individual roll shape formed by dividing a single weight roll extending over the entire width of the corrugated cardboard sheet as used in the prior art into a plurality of shorter weight rolls aligned in the width­wise direction, each of the weight rolls 4 is pivotably supported by pins 7 projected from free ends of a pair of arms 6 via self-aligning bearings 5 provided at its oppo­site ends, and the other ends of the same arms 6 are pivotably secured to the fulcrum shaft 9 via bushes or bearings 8.
  • the opposite ends of the fulcrum shaft 9 are fixedly secured to frames not shown which are positioned on the opposite sides of the heating part 10.
  • the weight rolls 4 formed in the above-described manner are aligned in multiple in the widthwise direction of the corrugated cardboard sheet to form a weight roll row, and the weight rolls 4 in adjacent two rows are disposed in a staggered relationship so as to form a checker pattern along the traveling direc­tion of the double-faced corrugated cardboard sheet 3.
  • the arms 6 for pivotably supporting one row of weight rolls 4 and arms 11 for pivot­ably supporting another row of weight rolls 4 disposed at adjacent positions are illustrated to be pivotably supported from the same fulcrum shaft 9 in the figure, modification could be made such that the row of arms 6 and the row of arms 11 are pivotably supported respectively from different fulcrum shafts.
  • the stoppers 12 are provided for the pur­pose of restraining the position of the arms 6 and 11 in the axial direction.
  • the respective weight rolls 4 can swing individually, even in the event that the upper surface of the heating box 13 has deformed along the width­wise direction due to temperature variations, the respective weight rolls 4 can swing by the distance corresponding to the amount of deformation so as to follow the deformation, and therefore, always uniform pressing forces W can be applied to the surface of the double-faced corrugated card­board sheet via the canvas belt 14 as shown in Fig. 4. Accordingly, heat and tension applied to the corrugated cardboard sheet 3 can be made uniform over the entire region in the widthwise direction, and so, various troubles in the prior art as described previously can be eliminated.
  • the double facer according to the present invention is constructed in the above-described manner, uniform pressing forces over the entire region in the widthwise direction of the liner sliding along the heating box can be applied to the corrugated cardboard sheet. Accordingly, a uniform heating temperature and a uniform frictional resistance (tension) can be applied to the liner over its entire width, and so, prevention of loss sheets caused by poor sticking or the like and insurance of quality of a corrugated cardboard sheet can be expected.
