Definitions

  • the invention relates to a device for winding material webs, in particular paper or cardboard webs, onto winding cores according to the preamble of patent claim 1.
  • a winding device which has a driven support roller and winding stations arranged on both sides of the support roller.
  • Each winding station consists of two swiveling support arms, each of which is equipped with a hydraulic winding drive.
  • the two hydraulic motors of a winding station are connected in parallel and are fed by a hydraulic variable pump.
  • EP-A-0 324 707 describes a generic winding device in which a DC magnetic motor of high power density with special permanent magnets is used as rotary drives for the guide heads.
  • the invention has for its object to provide a generic device with an electric motor as a rotary drive, which has a small motor volume with high power (high power density), the winding stations can be easily adjusted to different formats, especially very narrow formats.
  • Liquid-cooled three-phase asynchronous motors provide the required acceleration and braking performance with a relatively small size.
  • the size of the motor is important because the support elements (e.g. winding frames) and the motors must be kept as close as possible to one another for small format widths.
  • the liquid-cooled motors also require supply hoses for the coolant, the pressure required in the hoses is significantly lower than in the supply hoses of hydraulic drives. It has been shown that a fluid pressure of 0.1 bar is sufficient. Due to the low pressure, the feed hoses are very flexible and can therefore easily adjust their position when changing formats.
  • the subclaims contain preferred, since particularly advantageous, embodiments of the invention.
  • the use of a three-phase asynchronous motor with a water- or oil-cooled stator winding according to claim 3 enables a small motor volume with high output, since in these motors the heat is generated mainly in the stator winding and the control via a frequency converter is the least complex (claim 4).
  • a supply roll not shown
  • a driven support roller 8 On both sides of the support roller 8 there are winding stations 9, 10, each consisting of two support elements which can be moved parallel to the support roller axis.
  • the support elements are winding blocks 11, 12, and the use of pivotable support arms is also possible.
  • Each winding block 11, 12 carries on its upper side a slide 13, 14 which can be moved radially to the support roller 8 and on which a guide head 15, 16 is fastened with its rotary drive 17, 18.
  • the guide heads 15, 16 are retractable for holding and driving the winding roll 19, 20 in its winding tubes.
  • Three-phase asynchronous motors are used as rotary drives 17, 18, the stator winding of which is cooled with water. Cooling with oil is also possible.
  • the housings of the motors 17, 18 have circumferential cooling channels for the cooling liquid. So that the winding stands 11, 12 can be moved as close as possible to one another for narrow formats, the motors 17, 18 are installed in the longitudinal direction, that is to say in the web running direction, and are connected to the guide heads 15, 16 via an angular gear.
  • the gears are flanged to the motors 17, 18, each flange also having cooling channels. In the flange area, cooling can be increased to also dissipate heat generated in the transmission.
  • a regulating or control device (not shown) regulates or controls the winding hardness of the winding rollers 19, 20 via the torques of the motors 17, 18.
  • the torque regulation or control is carried out via a frequency converter.
  • direct current or servo motors can also be used, the stator winding of which is cooled with water or oil.
  • DC motors require more complex maintenance due to the wear of carbon brushes, and a complex control concept is required for servomotors.
  • the cooling channels of the motors 17, 18 are connected to supply hoses for coolant, which are supplied by a common cooling system outside the winding machine.
  • the supply hoses on each side of the winding machine are combined into tows, due to the low pressure in the hoses (0.1 bar), the hoses are very flexible and can therefore be arranged in a space-saving manner and easily moved with a format adjustment. Furthermore, the risk of leaks is minimal at the low pressure.
  • a longitudinal cutting device 21 is arranged above the support roller 8 in the area between the guide rollers 6 and 7 and consists of a plurality of pairs of circular knives 21.1, 21.2 which can be adjusted transversely to the running direction to different format widths of the individual webs to be cut.
  • a roller 22 is supported on the side pivot levers 23 against the support roller 8 in the area wrapped by the webs 1.
  • the roller 22 serves, together with the support roller 8, to interrupt the tension of the webs 1 in front of the winding stations 9, 10.
  • the tension behind the nip formed by the roller 22 and the support roller 8 is determined by the torques of the motors 17, 18 by means of a frequency converter regulated to the value required for the desired winding hardness.
  • the tension for each winding roller 19, 20 can be regulated individually via the motors 17, 18, so that each winding station 9, 10 can be operated as an independent winding machine.
  • the winding machine is preferably used for producing rolls with a large diameter (for example 1.5 m) from HWC (High Weight Coated) papers. These papers are sensitive to marking so that the line force on the support roller 8 should be kept low. Since the tension of the web 1 required for winding is applied by the drives 17, 18, the line force with which the winding rollers 19, 20 are pressed against the support roller 8 can be kept at values less than 30 N / m during the winding. The line force should, however, be at least 10 N / m, so that no air is wrapped in and 1 round winding rolls are wound even in the event of profile fluctuations in the web.
