Definitions

  • the invention relates to a gluing device, in particular for book blocks to be hung in book cover machines in book covers, with an application roller assigned to a surface area to be glued, rolling on this and thereby leaving a layer of glue, and with a metering roller assigned to this in the opposite direction of rotation, the for glue application Application roller is provided with an axially parallel recess and the metering roller is provided with an axially parallel projection engaging in it.
  • the application roller serves to provide the surface area of the book block to be glued with the required glue application
  • the metering roller conveys the correct uniform glue application to the application roller, for example from a glue bead present in the roller wedge.
  • the axially parallel depression the application roller picks up the projecting fold of the book block and ensures that it is correctly glued.
  • the protrusion of the metering roller dips into the recess as it passes through the common rolling zone, on the one hand to ensure the closure in this area and on the other hand to ensure the correct application of glue in the recess.
  • the interacting profiles of the depression of the application roller and the projection of the metering roller are particularly important. These profiles must be designed in such a way that, when they mesh with one another in the rolling zone, they maintain the correct closure of the roller wedge, enable the glue bead located between the rollers to escape unhindered without the risk of inclusions, and ensure correct glue application on the active surfaces of the recess. Until now, these various requirements could only be met with relatively complicated profiles that were difficult to manufacture.
  • the object of the invention is to provide a gluing device of the type specified in the introduction, in which the specified requirements are optimally met with a simple and easy-to-produce profile shape of the rollers.
  • this object is achieved in that the profile of the projection on the inlet section lying at the front in the direction of rotation passes over an involute from the circular-cylindrical circumferential surface of the metering roller to a coaxial circular-cylindrical section of larger diameter, and in that the profile of the depression at the Direction of rotation at the front of the inlet section via a counter-profile to the involute of the projection Curve passes from the circular cylindrical peripheral surface of the applicator roller to a coaxial circular cylindrical section of smaller diameter.
  • the curve forming the profile of the inlet section of the depression is an involute forming the counter profile to the involute of the projection.
  • the involutes of the protrusion and the depression are preferably designed with a pressure angle of 45 °.
  • a further advantageous embodiment of the gluing device according to the invention consists in that the profile of the projection at the outlet section lying at the rear in the direction of rotation passes over an eccentric circular-cylindrical section of smaller diameter from the coaxial circular-cylindrical section to the circular-cylindrical peripheral surface of the metering roller and that the transition from the recess from the coaxial circular cylindrical section of small diameter to the circular cylindrical peripheral surface of the applicator roller in the outlet section is designed as a counter-profile to the eccentric circular cylindrical outlet section of the projection.
  • the inventive design of the profiles of the recess of the applicator roller and the projection of the metering roller ensures that when the projection is immersed in the recess as a result of the rolling of the involute flank on the matching counter profile, the glue bead can escape unhindered without the risk of inclusions.
  • the secure closure of the roller wedge is guaranteed throughout the passage through the rolling zone.
  • the coordinated profiles of the projection and the depression ensure the correct application of glue, in particular on the surface section of the depression which is effective for glueing the fold.
  • a particular advantage of the profile design according to the invention is the inexpensive producibility because of the simple geometry, since the profiles essentially consist only of circles and involutes, which are easy to construct and can be produced by machine without problems.
  • Fig. 1 shows schematically in side view that a gluing unit of a gluing device for a book hanging machine.
  • the gluing unit essentially consists of an application roller 1 and a metering roller 2, the circumferential profiles of which can be seen in the drawing.
  • the application roller 1 has a circular cylindrical peripheral surface 3 with the radius R 1 over the largest part of its circumference, and the metering roller 2 is designed in a corresponding manner over the largest part of its circumference with a circular cylindrical peripheral surface 4, which preferably has the same radius R 1 .
  • the axes of the two rollers lie in a common horizontal plane of diameter, the center distance being substantially equal to the sum of the two radii R 1 , so that the rollers 1 and 2 are wholly or almost tangent in a rolling zone 5.
  • a glue supply device not shown, ensures a constant amount of glue 6 in the wedge of the two rollers 1 and 2.
  • the two rollers 1 and 2 are driven in opposite directions in the direction of the arrows, so that their peripheral surfaces pass through the rolling zone 5 from top to bottom.
  • the metering roller 2 ensures that the surface of the application roller 1 takes a glue application of predetermined thickness.
  • the amount of glue applied can be determined by the center distance of the two rollers and / or by depressions in the surface of the application roller 1.
  • the application roller 1 transfers the glue application carried along to one side of a book block 7, which comes in contact with the application roller 1 from below at the point substantially diametrically opposite the rolling zone 5 is moved upwards.
  • the gluing device contains a second gluing unit, which is arranged in mirror image to the gluing unit shown, but is not shown for simplification.
  • the application roller 1 is provided with a recess 10 which is so deep that it can accommodate the fold 8 of the book block 7.
  • a projection 20, which is complementary to the depression 10, is formed on the metering roller 2 and dips into the depression 10 when the rollers rotate as it runs through the rolling zone 5 (FIG. 2).
  • the projection 20 ensures that during this passage through the rolling zone the amount of glue 6 in the roller wedge is retained and the surfaces of the depression 10 receive the glue application required for the correct gluing of the fold 8.
  • the profiles of the depression 10 and the projection 20 are important for this.
  • the depression 10 and the projection 20 run parallel to the axes of the rollers 1 and 2, that is to say perpendicular to the plane of the drawing in FIG. 1, with a constant profile, as will be explained below with reference to FIG. 1.
  • the profile of the depression 10 consists of three sections, namely the inlet section 11 leading in the direction of rotation, the central section 12 forming the lowest point and the outlet section 13 trailing in the direction of rotation.
  • the profile of the projection 20 consists of three sections, namely the Inlet section 21 leading in the direction of rotation, middle section 22 forming the largest elevation and outlet section 23 trailing in the direction of rotation.
  • the middle section 12 which takes up the largest part of the angular extent of the depression 10, is formed by a circular cylindrical surface coaxial with the peripheral surface 3 of the application roller 1, the radius R 2 of which is smaller than the radius R 1 of the peripheral surface 3.
  • the angular expansion a of the circular-cylindrical central section 12 can be approximately 30 °.
  • the central section 22 of the projection 20 is formed by a circular cylindrical surface coaxial with the peripheral surface 4 of the metering roller 2, the radius R 3 of which is greater than the radius R 1 of the peripheral surface 4 by the radius difference AR.
  • the central section 22 has the same angular extent a as the central section 12 of the depression 10.
  • the inlet section 11 of the recess 10 forms the transition from the circular cylindrical peripheral surface 3 to the circular cylindrical central section 12, and in a corresponding manner the inlet section 21 of the projection 20 forms the transition from the circular cylindrical peripheral surface 4 to the circular cylindrical central section 22.
  • the profiles of these transitions are therefore important when the protrusion 20 enters the recess 10, the correct termination is ensured in the rolling zone 5 and the glue bead previously penetrated into the recess 10 can escape upwards without undesired inclusions.
  • the profile of the inlet section 21 of the Projection 20 is formed by an involute, so that the front flank of the projection 20 forming the inlet section 21 of the tooth flank corresponds to an involute toothing.
  • the profile of the inlet section 11 of the recess 10 forms the required counter profile to the involute flank of the projection 20.
  • this counter profile is also formed by an involute, so that the two inlet profiles interact like the tooth flanks of an involute toothing and interact when the projection 20 enters the recess 10 roll on each other according to the gearing laws.
  • these are circular involutes, the radius of the base circle of the involutes being smaller than the radius R 1 of the rollers.
  • the involute flanks of the inlet sections 11 and 21 are preferably designed with a pressure angle of 45 °. With this profile shape, the optimal conditions are achieved when the projection 20 enters the recess 10. Furthermore, the involute flanks 11 and 21 can be constructed and manufactured in a simple manner using the known toothing technology.
  • the outlet section 13 of the recess 10 forms the transition from the recessed circular-cylindrical middle section 12 to the circular-cylindrical peripheral surface 3, and it is the part of the recess 10 which brings about the gluing of the fold 8.
  • the outlet section 23 of the projection 20 forms the transition from the circular-cylindrical section in a corresponding manner Middle section 22 to the circular-cylindrical peripheral surface 4, and it cooperates with the outlet section 13 of the recess 10 when the projection 20 runs out of the recess 10 to achieve the correct application of glue.
  • the profile of the outlet section 23 of the projection 20 is formed by a circular cylindrical surface section whose radius R 4 is substantially small ner than the radius R 1 of the peripheral surface 4, and whose axis is eccentric to the axis of the metering roller 2.
  • the circular cylindrical outlet section 23 with the radius R 4 tangentially adjoins the circular cylindrical middle section 22 with the radius R 3 and extends over a central angle ⁇ which is greater than 60 ° and less than 90 °.
  • the profile of the outlet section 13 of the recess 10 is formed as a counter profile to the profile of the circular cylindrical outlet section 23 of the projection 20, so that the profiles roll on each other as they pass through the rolling zone 5 (FIG. 4) and thereby achieve the required conclusion and the achievement of ensure correct glue application.
  • the resulting profile shape of the outlet section 13 also results in the correct gluing of the fold 8.
