Definitions

  • the invention relates to a device and a method for applying adhesive, in particular for gluing sheet stacks, consisting of an application roller immersed in an adhesive pool with at least one doctor blade which can be set against the circumference of the application roller.
  • the sheet stack is clamped in a holder and guided along a linear or curved path.
  • the back of the stack of sheets to be glued slides over a rotating applicator roller that dips part of its circumference into an adhesive basin.
  • wiping devices e.g. Squeegees, which can be set against the circumference of the application roller.
  • the object of the invention is to develop an adhesive application device with an application roller driven in the optimum direction of rotation, with the aid of which it is possible to bring about a uniform and intensive coating of the workpiece to be machined, without complicated and costly adjustment measures being necessary for this.
  • the object of the invention is not only directed to the gluing of sheet stacks but can also be directed to the coating of other workpieces, also with other liquid or pasty substances.
  • the invention is characterized by a reversible direction of rotation drive for the application roller and by the arrangement of an adhesive metering container on the outlet side of the application roller within the adhesive tank, the metering container forming two gap-like passages relative to the jacket of the application roller, of which the upper, the workpiece to be glued facing gap is wider than the lower one.
  • the edges of the metering container facing the application roller are preferably designed as doctor blades or similar scraping devices.
  • the reversible drive for the applicator roller first ensures that the optimal direction of rotation can be set for the coating of the workpiece, while the reverse direction of rotation can be used for the start of gluing. This means that the thickening of the coating to be found in the known method no longer occurs on the leading side of the workpiece.
  • the method for applying adhesive to a sheet stack back with a device according to the invention teaches that the application roller is first driven in a direction of rotation in the same direction as the feed of the sheet stack until the leading edge of the sheet stack has reached the application position, whereupon the direction of rotation the application roller is reversed. It is advisable here if the drive of the application roller is controlled by switches which can be actuated by the leading and trailing edges of the sheet stack or their tensioning devices.
  • sheet stack can be replaced by "workpiece”, provided that other objects also need to avoid thickening of the coating on the leading edge of the workpiece.
  • the arrangement of a metering container on the discharge side of the application roller which is also provided according to the invention, has the purpose of continuously carrying out the required, uniform amount of the coating substance on the workpiece to be coated, even if the application roller is reversed in its direction of rotation according to the invention.
  • the fact that the application roller rotates in the same direction as the feed of the workpiece to be coated before the start of the coating work is different because of the dimensioned gap between the edges of the metering container facing the applicator roller and the applicator roller brings about a filling of the metering container, so that more substance is conveyed into the metering container than can get out of it.
  • the leading area of the workpiece is coated with this direction of rotation.
  • the direction of rotation of the application roller is reversed, which means that the substance is now removed from the dosing container and transferred intensively to the workpiece when the application roller rotates in the opposite direction to the feed direction. If, according to the invention, the volume of the dosing container is several times larger than the maximum amount of adhesive required for a workpiece, then a uniform but also sufficient coating of the workpiece is achieved.
  • a further doctor blade is arranged on the inlet side of the application roller, the distance from the application roller is smaller than the upper gap width, but larger than the lower gap width between the dosing container and the application roller.
  • This squeegee prevents an excessive amount of substance from being carried along by the application roller if it rotates in the same direction as the workpiece is fed before the application work begins.
  • This doctor blade can also be used as a cylinder, for example be shaped, fixed rod and enforce the adhesive pool. Of course, this doctor blade can also be arranged to be adjustable.
  • the invention provides in a further exemplary embodiment that the upper doctor blade of the metering container is arranged above the axis of the application roller and the normal adhesive level in the adhesive tank.
  • the static pressure of the medium present in the adhesive tank thus has practically no influence on the substance present in the dosing container.
  • the substance present in the dosing container is located in its mirror much closer to the workpiece to be coated, so that in this way the risk of evaporation of the solvent possibly present in the substance is also substantially reduced.
  • FIGS. 1 and 2 shows the gluing of a sheet stack 14 which is clamped in the usual way and can be moved along a rotatably arranged application roller 3.
  • This application roller 3 is located in an adhesive basin 1 and is intended for the adhesive removed from the basin 1 to pass to the sheet edges of the sheet stack 14.
  • a metering container 2 On the outlet side of the application roller 3 there is a metering container 2 which, with the walls 7 (see FIG. 3), engages around the front of the application roller 3 and seals the metering container 2 there from the adhesive tank 1. With its upper and lower wall, the metering container 2 extends close to the application roller 3.
  • these upper and lower walls are designed as doctor blades 5 and 6.
  • the doctor blade 5 has a larger gap 11 than the doctor blade 6 with the gap 10 with respect to the application roller 3.
  • the inner surface of the doctor blade 5 is located above the axis of the application roller 3 and thus above the normal level inside the adhesive tank 1.
  • an overflow opening 8 is preferably provided in the upper region, through which the one located in the metering container 2 Substance can get back into the adhesive pool 1.
  • the application roller 3 is provided with a drive, not shown, reversible in the direction of rotation.
  • This drive can be reversed by means of special switches, which can be actuated in particular by the leading and trailing edges of the workpiece 14.
  • the arrangement according to the invention works as follows: In the position shown in FIG. 1, in which a workpiece 14 is still at a distance from the application roller 3, the application roller 3 rotates in the same direction as the direction of advance of the workpiece 14, which is indicated by the direction of rotation arrow 12. In this direction of rotation, the applicator roller 3 takes the adhesive (or another substance) located in the adhesive basin 1 in a counterclockwise direction, the doctor blade 4, which according to the exemplary embodiment can also be designed as a cylindrical rod, only lets through an amount of substance corresponding to the gap 9. The substance entrained on the circumference of the application roller 3 passes through the gap 11 into the metering container 2, where it is essentially retained because the gap 10 of the doctor blade 6 has a smaller width than the gap 11 of the doctor blade 5. If, in this direction of rotation 12 of the applicator roller 3, there is an excess delivery quantity for the metering container 2, the substance can escape again into the adhesive tank 1 through the overflow opening 8.
  • the direction of rotation of the application roller 3 is reversed by a switch (not shown) depending on the leading edge of the workpiece 14, so that it now moves in the direction of the arrow 12 2 revolves.
  • the substance to be applied is now removed from the metering container 2, which is continuously emptied because the gap 10 is smaller than the gap 11.
  • the volume of the metering container 2 is substantially larger than the amount of substance to be applied to the individual workpiece 14, there can be no danger.
