Definitions

  • the invention relates to a device for applying a liquid adhesive on a passing object, consisting of a tub containing the adhesive, on which a transfer roller partially immersed in the adhesive is rotatably mounted about a horizontal axis.
  • Such facilities include when labeling objects or in perfect binding technology during production of adhesive-bound book blocks and books, brochures etc. known.
  • the transfer roller or rollers are driven by a shaft passing through the walls of the adhesive trough, on which the transfer roller is mounted.
  • the partly chemically aggressive Adhesives and alternately heating and cooling of the adhesives occupy those below the surface of the adhesive located bearing seals of the transfer roller visibly and leave behind after a certain period of use a leaky tub.
  • EP - A - 0 587 026 is a gluing unit for perfect binding machines known, which is located on the drive shaft outside of the glue tank half of one of two slices existing magnetic coupling and on the one stored in the glue unit Transfer roller the other half of the magnetic coupling located. Both halves of the magnetic coupling lie coaxially on both Sides of a pool wall facing each other. The one another facing end faces of the magnetic coupling halves are magnetized.
  • the object of the invention is therefore a device according to the to create the type described above, in which the leak fixed the tub and a related maintenance is not required.
  • the trough has the stator of the transfer roller designed as a rotor of an electric motor.
  • AC or DC motors with a magnetic rotor, electric motors with squirrel-cage rotors, eddy current motors, stepper motors, reluctance motors or other motors for generating a rotating field can be used as electric motors.
  • Both internal and external rotor motors are suitable for the device according to the invention.
  • the symmetrical structure of an electric motor prevents one-sided acting forces.
  • Trough 2 which has the stator 4 of a transfer roller 7 designed as a rotor 16 of an electric motor 6, is used for mounting the transfer roller 7 provided bores 8, the illustrated embodiment having an additional bearing block 9 for the double bearing of the transfer roller 7, which could also be overhung in the wall 10 of the tub 2.
  • the stator 4 of the electric motor 6 is provided on both sides of the rotor 16 and installed on the one hand in the wall 10 of the trough 2 and on the other hand in the rib-like bearing block 9.
  • the stator 4 generating a rotating field has an iron core 12 surrounded by an electrical field winding 11 - see FIG.
  • the transfer roller 7 consists of a non-magnetizable rotor 16 which has laterally projecting shaft journals 17.
  • the rotor 16 has one on each side of the permanent magnet 5 Guide ring 13 for the magnetic flux under the permanent magnet 5.
  • FIG. 4 illustrates an external rotor motor Electric motor 6, in which the rotating field generating Stator 4 formed in a ring and acting on the circumference of the Wall 10 is arranged in the tub 2.
  • the permanent magnet wheel-shaped rotor 16 surrounds the stator 4 and is through a lateral non-magnetizable disk 20 with one hand in the wall 10 and on the other hand in the bearing block 9 of the Tub 2 bearing shaft 18 connected.
  • Fig. 5 mediates an internal rotor motor in a correspondingly analog Arrangement as in FIG. 4.
