Definitions

  • the present invention relates to a pasting device for a glue machine to be equipped in a corrugate machine.
  • FIG. 2 One example of a pasting device for a glue machine in the prior art is illustrated in Figs. 2 to 4, and an arrangement of a glue machine and a double-facer apparatus in the prior art is shown in Fig. 5.
  • a double-facer apparatus is composed of a heating part 13 and a cooling part 14, and in this apparatus a single-faced corrugated cardboard sheet 1 produced by a single-facer (not shown) in the preceding step and a liner 15 fed through a separate route are stuck together and a double-faced corrugated cardboard sheet 5 is manufactured.
  • the above-mentioned heating part 13 is constructed of a preheat section 16, a heating box (hot plate section) 17, a canvas belt 18 and a pressing mechanism 19.
  • the above-described cooling part 14 is constructed of a conveyor belt 20, a canvas belt 18 and a pressing mechanism 21.
  • the single-faced corrugated cardboard sheet 1 produced by the single-facer in the preceding step has paste (starch) 2 applied to its hill-shaped corrugate crest portions in the glue machine 3, and then it is transferred to the double-facer heating part 13 on the downstream side.
  • the liner 15 is, after preheated in the preheat section 16, similarly transferred to the double-facer heating part 13 on the downstream side.
  • the single-faced corrugated cardboard sheet 1 and the liner 15 joined at the sheet introducing port section of the heating part 13 are pinched between the canvas belt 18 that is made to travel by a roll 23 driven by a motor 22 and the heating box (hot plate section) 17 thereunder, and further they are conveyed to the cooling part 14 on the downstream side as pressed by weight rolls 24.
  • the double-faced corrugated cardboard sheet 14 formed by sticking is pinched between the canvas belt 18 and the conveyor belt 20 positioned above and below and is conveyed as applied with an appropriate pressing force by the pressing mechanism 21, thereby the sticking condition between the single-faced corrugated cardboard sheet 1 and the liner 15 is more assured, and also warp deformation of the board that is liable to occur upon cooling is amended.
  • reference numeral 4 designates a pasting device, and this pasting device 4 is composed of a pasting roll 6, a doctor roll 25 disposed in opposi­tion to the same pasting roll 6 as apart therefrom by a predetermined gap clearances, a blade 26 that is movable in the axial direction of the doctor roll 25, a paste reservoir 27 and a press roll 28.
  • a rotary drive mechanism for the above-mentioned pasting roll 6 is constructed in the following manner. That is, reference numeral 29 in Fig.
  • numeral 2 designates a roll of the canvas belt 18
  • numeral 30 designates a sprocket coaxial with the same roll 29
  • numeral 34 designates a gear coaxial with the pasting roll 6
  • numeral 33 designates a gear meshed with the same gear 34
  • numeral 32 designates a sprocket co­axial with the same gear 33
  • numeral 31 designates a chain suspended between the same sprocket 32 and the aforementioned sprocket 30.
  • rotation of the roll 30 of the canvas belt 18 is transmitted to the pasting roll 6 through the route of roll 29 ⁇ sprocket 30 ⁇ chain 31 ⁇ sprocket 32 ⁇ gear 33 ⁇ gear 34 ⁇ pasting roll 6, thereby the pasting roll 6 is rotated, and a circumferential velocity (V R ) of the pasting roll 6 is made to coincide with a traveling velocity (V S ) of the single-faced corrugated cardboard sheet 1.
  • the paste 2 in the paste reservoir 27 is scooped up by the pasting roll 6 rotating in the direction of an arrow, while surplus paste 2 is scraped out by the doctor roll 25 to make a thickness of paste 2 rotationally moving jointly with the pasting roll 6 constant, and this paste 2 is brought into contact with hill-shaped corrugate crest portions of the single-faced corrugated cardboard sheet 1 to transfer the paste 2 on the pasting roll 6 to the hill-shaped corrugate crest portions.
  • the pasting device for use in a glue machine in the prior art as shown in Figs. 2 to 4 involved the following problems. That is, when the paste 2 on the pasting roll 6 is transferred to the hill-shaped corrugate crest portions of the single-faced corrugated cardboard sheet 1 by bringing the paste 2 having a constant thickness and rotationally moving jointly with the pasting roll 6 into contact with the hill-shaped corrugate crest portions of the single-faced corrugated cardboard sheet moving in the direction of an arrow, it is desirable that a circum­ferential velocity V R of the pasting roll 6 and a traveling velocity V S of the single-faced corrugated cardboard sheet 1 coincide with each other.
  • FIG. 3(a) shows the case of V S > V R while Fig. 3(b) shows the case of V S ⁇ V R .
  • V S > V R shown in Fig.
  • the paste 2 on the pasting roll 6 would be scraped up towards the down­stream side by the hill-shaped corrugate crest portion of the single-faced corrugated cardboard sheet 1, hence the transferred amount of paste on the downstream side with respect to the traveling direction of the hill-shaped corrugate crest portion is increased, whereas in the case of V S ⁇ V R shown in Fig. 3(b), the paste 2 on the pasting roll 6 would be scraped up towards the upstream side by the hill-shaped corrugate crest portion of the single-­faced corrugated cardboard sheet 1, and so, the transferred amount of paste on the upstream side with respect to the traveling direction of the hill-shaped corrugate crest portion is increased.
  • the present invention has been proposed in view of the aforementioned problems in the prior art, and it is a principal object of the present invention to provide a pasting device for use in a glue machine, in which products having a large strip-resistance force can be obtained and yet consumption of paste can be minimized.
  • a pasting device for use in a glue machine to be equipped in a corrugate machine, com­prising a detector for detecting a traveling velocity of a single-faced corrugated cardboard sheet, and a control device responsive to a detection signal issue from the detector for calculating a control signal for making a circumferential velocity of a pasting roll coincide with the traveling velocity of the single-faced corrugated cardboard sheet and applying this control signal to a rotational drive motor for the pasting roll, whereby the circumferential velocity of the pasting roll can be varied depending upon the traveling speed of the single-faced corrugated cardboard sheet.
  • a traveling velocity of a single-faced corrugated cardboard sheet is detected by a detector, a resultant detection signal for the traveling velocity of the single faced corrugated cardboard sheet is sent to a control device, in which a control signal for making a circumferential velocity of a pasting roll coincide with the traveling velocity of the single-faced corrugated cardboard sheet is calculated, and this control signal is applied to a rotational drive motor of the pasting roll, whereby the circumferential velocity of the pasting roll can be made to coincide with the traveling velocity of the single-faced corrugated cardboard sheet.
  • a double-facer apparatus is composed of a heating part 13 and a cooling part 14, and in this apparatus, a single-faced corrugated cardboard sheet 1 produced in a single-facer (not shown) in the pre­ceding step and a liner 15 fed through a separate route are joined together, and thereby a double-faced corrugated cardboard sheet 5 can be produced.
  • the above-mentioned heating part 13 is constructed of a preheat section 16, a heating box (hot plate section) 17, a canvas belt 18 and a pressing mechanism 19.
  • the above-­described cooling part 14 is constructed of a conveyor belt 20, a canvas belt 18 and a pressing mechanism 21, and the single-facer produced in the preceding step has paste (starch) 2 applied to hill-shaped corrugate crest portions in a glue machine, and is transferred to the double-facer heating part 13.
  • the liner 15 is, after preheated in the preheat section 16, likewise transferred to the double-facer heating part 13 on the downstream side.
  • the single-faced corrugated cardboard sheet 1 and the liner 15 joined at the sheet introducing port section of the heating part 13 is pinched between the canvas belt 18 that is made to travel by a roll 23 driven by a motor 22 and the heating box (hot plate section) 17 thereunder, and further they are conveyed to the cooling part 14 on the downstream side while being pressed by weight rolls 24.
  • the double-faced corrugated cardboard sheet 5 formed by sticking is pinched between the canvas belt 18 and the conveyor belt 20 positioned above and below, and is con­veyed while it is applied with an appropriate pressing force by the pressing mechanism 21, thereby the stuck condition of the single-faced corrugated cardboard sheet 1 and the liner 15 is more assured, and furthermore, warp deformation of the board that may possibly occur upon cooling is amended.
  • a traveling velocity detecting roller (detector) 7 provided in the vicinity of a pasting device 4a is brought into contact with the single-faced corrugated cardboard sheet 1 to be rotated, and on the basis of a rotational speed of the traveling velocity detecting roller 7 obtained by an encoder directly coupled to the traveling velocity detect­ing roller 7, a traveling velocity V S of the single-faced corrugated cardboard sheet 1 can be detected.
