Definitions

  • the present invention relates to a device making it possible to carry out the instantaneous change of glued width during the manufacture of corrugated cardboard, in particular single-sided, more particularly during the passage of an automatic connection between two reels of fluted paper of widths. different.
  • the invention also relates to a method of using this device.
  • the strip of fluted paper is corrugated by the passage between two fluted rolls and glued to a strip of cover paper between the lower grooved cylinder, placed downstream, and a smooth cylinder around which the cover paper passes.
  • the glue is deposited on the top of the corrugations of the corrugated paper using a glue roller driven in rotation and soaking in a glue tank.
  • the width of the gluing zone that is to say the zone of the cylinder wetted by the glue, is conventionally imposed, as described in detail in the aforementioned French patent 2,433,985, by the adjustable distance between two barriers, both in the glue tank.
  • gluing area is less than the width of the corrugated paper strip, waste is produced by lack of gluing at the edges.
  • the gluing area is greater than the width of the corrugated paper strip, the excess glue is then deposited on the lower corrugated cylinder, causing it to become clogged, which means that machine stops for cleaning.
  • These two problems have become crucial due to the widespread use of reel launchers making it possible from now on to connect practically end to end the end of one reel on the beginning of the other.
  • the gluing area remains the same and there is no difficulty.
  • the vagaries of the manufacturing programs mean that often the width of the successive reels is not the same, and it is then necessary to modify the position of the barriers so that the gluing area corresponds to the new width of the paper being worked. This movement takes some time and as the change in width of the paper is instantaneous, there is either waste due to lack of collar lage, or fouling of the lower grooved cylinder.
  • the device of the invention makes it possible to instantly change, therefore without stopping the machine, the width of the gluing area of the gluing cylinder when the connection of the two coils passes. It is characterized in that it also comprises a removable auxiliary scraping device, comprising two scrapers intended to be applied momentarily to the two ends of the gluing cylinder, on the non-submerged upstream part thereof, this scraping device being also equipped with means for adjusting the distance left free for the adhesive to pass between the two doctor blades, and with means for moving the doctor blades between an active position pressing on the gluing cylinder and a release position out of contact with the cylinder .
  • a removable auxiliary scraping device comprising two scrapers intended to be applied momentarily to the two ends of the gluing cylinder, on the non-submerged upstream part thereof, this scraping device being also equipped with means for adjusting the distance left free for the adhesive to pass between the two doctor blades, and with means for moving the doctor blades between an active position pressing on the gluing cylinder and
  • the scraper device consists of a cylinder provided with two end sleeves in excess thickness, symmetrical with respect to the transverse plane of symmetry of the cylinder, and the two opposite internal faces of which are cut in a helix so as to define a width free for the passage of the adhesive which varies continuously according to the fixed, but adjustable angular position, given to the cylinder.
  • the auxiliary scraper device consists of a metal roller 1 coated at its two ends with a non-metallic material, such as polyurethane, forming two sleeves 2 which make extra thickness.
  • the two sleeves 2 have a symmetry with respect to the transverse median plane 3 of the cylinder 1, and their facing internal faces 4 make an angle a with the horizontal and are cut in a helix as shown in the perspective of FIG. 2.
  • the roller 1 is brought in, using an irreversible motor at low speed 7 for example. the corresponding angular position b.
  • An angular measurement device such as a potentiometer 8 connected to an electrical measurement device, makes it possible to ensure that the roller 1 is indeed in the desired angular position b.
  • the motor 7 being irreversible, the cylinder 1 is then immobilized in rotation despite the contact with the glue cylinder 5 which itself rotates continuously.
  • the sleeves 2 form a doctor blade for the adhesive outside the space 6, and the latter falls back into the adhesive container where the cylinder 5 soaks.
  • FIGS. 3 and 4 schematically represent a single-sided gluing machine using, to allow instant change of glued width, the scraper device of FIGS. 1 and 2.
  • FIG. 3 a single-sided corrugator in which, in a very conventional manner, the corrugated paper 9 is corrugated by passing between an upper corrugated cylinder 10 and a lower corrugated cylinder 11, then glued to a cover paper 12 between the cylinder lower grooved 11 and a smooth cylinder 13.
  • the corrugated paper once formed, receives glue on the top of its corrugations via a gluing cylinder 5 of which the lower part is dipped in the glue 14 contained in the tray 15.
  • the thickness of glue deposited on the corrugated paper is regulated by the interval which exists between the glue cylinder 5 and a non-submerged cylinder 16, called the doctor cylinder.
  • the width of the gluing zone of the gluing cylinder 5 is imposed by the distance existing between two barriers 17, a distance which is adjustable, as can be seen in FIG. 4, by a conventional drive translation device 18 and endless screw 19 with inverted steps.
  • a further distinction is made between the conventional device for driving in rotation the gluing cylinder 5 with a motor 20 and angular gear 21.
  • a scraper device as described above with reference to FIGS. 1 and 2 can be temporarily applied to the top, upstream side, of the gluing cylinder 5.
  • the roller 1, furnished with its two sleeves 2 described above, is supported by two levers 22, each lever being articulated on a pivot 23 fixed in each frame 24 and controlled by a jack 25 also articulated on the corresponding frame 24.
  • the jacks 25 make it possible to obtain a high position in which the roller 1 is not in abutment on the gluing cylinder 5, which allows the free passage of the adhesive deposited on the cylinder after soaking in the tank 15.
  • the roller 1 presses on the cylinder 5 via the sleeves 2, then limiting the gluing area to the distance L which separates, on the contact generator of the roller 1 and the gluing cylinder 5, the two scraper sleeves 2.
  • the roller 1 can be rotated by means of the irreversible motor 7 and the pinion and chain transmission 26. It is thus possible to adjust the distance L desired between the two sleeves 2 before applying the roller 1 to the cylinder 5 As the motor 7 is irreversible, the roller 1, once brought to its angular position b for adjustment, is locked in this angular position despite contact with the cylinder 5 which itself turns continuously. The distance L is therefore kept for the entire contact time between the roller 1 and the cylinder 5. The excess glue due to the wiping of the cylinder 5 by the sleeves 2 is recovered in a transverse chute 27.
  • the roll 1 was raised and the width of the gluing area of the roll 5 was adapted to the width of the corrugated paper strip only by the barriers 17 of the glue tank.
  • the roller 1 still being in the high position, by means of the motor 7, the distance L between the two sleeves 2 is adjusted to the new smaller value.
  • a detection system 28 with a photocell for example, detects the connection of the two widths.
  • An electronic computer not shown, calculates the time that will elapse before the connection arrives at the location where the paper is glued, as a function of the distance to be covered and the speed of travel of the strip.
  • the jacks 25 are actuated to bring the roller 1 into contact with the cylinder 5, instantly limiting the gluing area to the new distance L corresponding to the new width worked. From this moment the barriers 17 are set in motion to come to be in accordance with the new width worked. Roller 1 can then be raised again. The excess glue due to the wiping of the cylinder 5 by the sleeves 2 during the movement of the barriers is recovered in the chute 27.
  • the roller 1 and the doctor blades 2 are again applied to the glue roller 5, which has no immediate effect since the gluing width determined by the barriers 17 is the same as that determined by the angular position of the helical doctor blades 2. It is then possible, by means of the motor 18, to progressively move the barriers 17 to their new position corresponding to the new large width. During the whole time of operation of the barriers 17 the excess glue entrained by the roller 5 will be removed by the doctor blades 2, and recovered by the chute 27.
  • the jacks 25 are actuated to raise the roller 1; the doctor blades 2 then cease their action and the gluing area is instantly brought to its new larger width determined by the bars laughs 17.
  • the invention is not strictly limited to the embodiment which has been described by way of example, but it also covers the embodiments which would differ from it only in details, in variant embodiments or by use of equivalent means.
  • other equivalent means could be used to adjust the variable spacing between the doctor blades 2 which would not necessarily be helical sleeves, as well as to move them selectively between an active position bearing on the ends of the gluing cylinder 5 and a release position out of contact with this cylinder 5.
