Definitions

  • the invention relates to a drive unit for a rotating roller, for example a pressure roller or guide roller in a machine for manufacturing and / or Finishing a running fibrous web, in particular from paper or cardboard, wherein the drive unit comprises a motor and a drive shaft.
  • This pressing or swiveling in or out of the process Guide roller is mainly used to capture and support the transfer of the Fiber web from one section to the next section within the above Machine used.
  • This roller presses against the fibrous web or against a threading strip separated in the edge region of the fibrous web, the is also called a ribbon or a tail.
  • Fibrous web over a screen suction roll, press roll or counter roll.
  • Such a pressure roller is known, for example, from US Pat. No. 4,014,740, the pressure roller also intended to eliminate the tendency of the web to flutter.
  • This patent discloses the transfer of a paper web from the press section into the dryer section. This takes place in the area where the web is not supported by a screen.
  • the pressure roller itself can have an individual drive, which is not explained in more detail in the patent specification, and is dimensionally shorter than the paper web and the support roller. For this purpose, the pressure roller can be swiveled into the transfer process.
  • drum motors that perform transport tasks in conveyor belts.
  • the bearing of such a drum motor is designed for double-sided loading, which makes it less suitable for the rotating rollers to be pivoted.
  • the object of the invention is to provide a drive unit for a rotating roller create with which the disadvantages mentioned can be avoided.
  • the object is achieved in that the drive unit within the rotating roller is arranged.
  • the motor in particular an electric motor
  • the roller with rotating roller shell Drive shaft is fixed.
  • the drive shaft is on one side beyond the end of the roller extended and serves as a bearing for the roller in this area. This end area is therefore also dimensioned stronger than the rest of the Drive shaft.
  • the reinforced end area is in the stool of the manufacturing and / or Refinement machine can be easily installed.
  • roller is shorter or less wide than the web and with it cooperating counter-roller is formed, it is easier to move.
  • the drive unit according to the invention allows the roller and drive only then and only in the process must be swiveled where and when the said transfer is to take place. This can be done in different sections of the paper and Carton machine, for example the press section, dryer section, reel, respectively.
  • the relatively simple construction and the low weight of the unit is from Advantage.
  • a particular advantage of the invention is that the unit can be retrofitted an existing machine can be installed. Installation is therefore also easier than before because the motor or the entire drive unit only from one side to be pushed onto the drive shaft. Installation is both from the right side as well as from the left side (driver or drive side) possible.
  • Another advantageous embodiment of the invention is that the interior the engine can be cooled with compressed air.
  • Another convenient solution can be that with the drive shaft an encoder is mechanically connected, which in turn via a Coupling with the protective cover and the rotating roller shell of the roller connected is.
  • the rotary encoder is arranged on that end of the roller that the Clamping area in the swivel arm is opposite.
  • the paper web is to be separated from a section 1, for example a press I, in the next treatment section, for example the Press II to be transferred.
  • the transfer point is marked with 1.
  • the paper web 2 or one runs from its side edge separated threading strips via a sieve 3 and a suction roller 4, via which also the sieve 3 runs.
  • the screen 3 is supported and tensioned by guide rollers 5.
  • the suction roller 4 forms with a pressure roller 6 or its outer roller shell 6a a nip N through which the web to be transferred or the threading strip 2 running. Both rollers 4 and 6 run in opposite directions to one another, as indicated by the arrow is. In addition, the roller 6 has an inner stabilizing Roll jacket 6a '.
  • the roller 6 is considerably smaller (in diameter and above all in length) dimensioned as the roller 4 and is with its own drive, i.e. drive unit 7 provided.
  • This drive unit 7 is more clearly visible in FIG. 2.
  • It comprises an electric motor 8 and a fixed drive shaft 9.
  • the positioning of the roller 6 takes place via a swivel arm 10, which is part of the Seating S of the paper machine is.
  • the pressure roller 6 can then depending on the operating situation in the ongoing process be pivoted in, as the double arrow in Figure 1 shows.
  • the roller rotates at a constant speed.
  • the roller 6 is pivoted into the paper web 2, that is to say in the operating position, the roller 6 is raised to the required operating speed.
  • the circumferential speed of both rollers must be the same (with the usual tolerances of the control technology).
  • the one-sided articulation of the roller 6 allows a much simpler Construction than with conventional double-sided motors.
  • roller 6 Due to its size and the integrated drive unit 7, the roller 6 is also Particularly suitable for retrofitting into an existing machine to be able to install. This design also enables the Use in the wet end of the paper machine, since the motor is exposed to splash water, Dust and foreign bodies are protected.
  • the installation is from the right side as well as from the left side possible without any problems.
  • roller shell in its place Vary the choice of diameter and length.
  • the motor 8 is cooled with compressed air.
  • Supply line 11 which leads from the outside into the drive shaft.
  • the fed Compressed air flows through channels 9c to the engine to be cooled and from there via channels 9d to an exhaust air line 12, from which the exhaust air flows outwards.
