Definitions

• the invention relates to a rotor reel with two, independently rotatable, mounted in a rotatable rotor for successive, continuous winding of
• Hot-rolled reels which each have a reel mandrel, which consists of several segments that can be expanded, which are supported on axially displaceable wedge-shaped sliding surfaces, and in which the reels can be cyclically moved from a starting position into a band-bundle transfer position and with devices for guiding incoming hot strip onto the coiler mandrel of the coiler standing in the starting position and for applying it to the coiler mandrel until slip-free detection of the strip.
• a rotor reel for cold strip has already become known from EP-PS 0 221 373, but it has the object of spreading or expanding the reel mandrels.
• EP-OS 0 707 904 already discloses a device for the winding of strip-shaped rolling stock, the first of which
• Carousel reel should be suitable, there is a risk that if the tape is wound longer in the winding position, the tape can be touched with the device swung out to apply the tape to the reel. Under no circumstances is it possible, if necessary a complete one in the winding position
• the present invention is therefore based on the object of designing a rotor reel for hot strip in such a way that very thin, fast-running hot strips can be wound without breaking out during winding and essentially without damage by the device for winding, whereby it should be ensured that if necessary complete coil can be wound in the starting position of the reel.
• the device for guiding and applying the incoming strip is arranged on a sliding carriage which is driven by power and parallel to the reel.
• the device for guiding and applying the incoming strip is arranged on a carriage which can be completely extended from the winding position, the device can also no longer interfere if, if necessary, a complete coil has to be wound in the starting position of the reel.
• pressure rollers and deflection shells are arranged on the carriage, the pressure rollers preferably being driven at a slightly higher speed than the tape speed, so that the tape cannot break out.
• Possible injuries and a band emergence, e.g. on the deflecting shells are avoided in that the deflecting shells are acted upon by a medium which is directed towards the band, preferably in the direction of the band running, via nozzles in the deflecting shells, so that the band is pressed away from the pressure medium against the reel mandrel by the deflecting shell becomes.
• FIG. 1 shows a rotor reel with the coil to be wound in the starting position and the finished wound coil provided in the band bundle transfer position
• FIG. 2 shows the device for guiding and applying the incoming strip into a rotor reel in a sectional view
• FIG. 3 shows the side view of the device for guiding and applying the incoming belt
• FIG. 4 shows an alternative to the device for guiding and applying an incoming belt according to FIG. 2.
• the hot strip 4 coming from a rolling mill, not shown, is conveyed by means of a medium 5, e.g. Air or water, pressed on the roller table 6.
• the speed of the very thin hot strip can e.g. 20 m / sec.
• a device 7 for guiding and applying the incoming strip is used so that the first turns of the coil to be wound can be wound on the reel 2 safely and without slippage.
• a completely wound coil 8 is shown on the reel 3.
• Tape end rollers 9, 10, which are arranged on catch shells 11, 12 which can be pivoted against the coil 8, are driven at a slightly lower speed than the tape speed, so that it is ensured that the tape end cannot swing around the reel 3, but lies firmly against the coil .
• the coil 8 After the coil 8 has been completed, it can be pulled off the reel 3 after the mandrel support bearing (not shown) has been pivoted away via the coil carriage 13.
• Fig. 2 shows the device 7 for guiding and applying the incoming tape. It consists of a frame 15 which can be moved on rails 14 and on which the winding unit 16 is arranged.
• the winding unit 16 consists of pressure rollers 17, 18, 19 and deflection shells 20, 21, 22.
• the pressure roller 17 and the deflection shell 20 are fastened to a swivel arm 23 and are attached to it around a pivot point 24 fixed to the frame 15 by means of a piston-cylinder Unit 25 pivoted.
• the pressure roller 18 and the deflection shell 21 are held by a swivel arm 26 which can be pivoted about a pivot point 27 by a piston-cylinder unit 28.
• the pressure roller 19 and the deflection shell 22 are also held by a swivel arm 29 which can be pivoted about the pivot point 30 by a piston-cylinder unit 31.
• the piston-cylinder units 25, 28, 31 can pivot the pressure rollers 17 to 19 and deflection shells 20 to 22 in a position-controlled manner from a winding position into an open position.
• the piston-cylinder units 25, 28, 31 can be switched to pressure control. There is a possibility that the distance between the reel mandrel and the position-controlled pressure rollers decreases before the tape tip enters the reel from pressure roller 17 to pressure roller 19, thus forming an inlet funnel.
• the frame 15 In the winding position, the frame 15 is fixed via hydraulically driven locking devices 32, so that no displacement of the frame and the winding unit 16 in the axial direction of the reel 2 can take place.
• the fixing can also take place via wedge surfaces which are acted upon by the displacement cylinder.
• FIG. 3 shows a side view of the frame 14 which has a bracket 33.
• the bracket 33 holds the motors 34, 34 'and the gears 35, 35' for the pressure rollers 17, 18 and 19, the pressure roller 19 not being shown in FIG. 3.
• Between the gears 35, 35 'and the pressure rollers 17, 18, drive shafts 36, 36' are provided, which on the one hand bring about the rotary drive of the pressure rollers 17 and 18 and on the other are able to compensate for the pivoting movement of the pressure rollers 17 and 18 and the deflection shells 20 and 21, not shown.
• FIG. 4 shows a winding unit 37 which can be seen as an alternative to the winding unit 16.
• the winding unit 37 is also held on a frame 15 which can be moved on rails 14.
• a swivel arm 38 is provided which holds the deflection shell 39.
• a bearing lever 40 is provided which carries the pressure roller 17.
• the bearing lever 40 can be pivoted relative to the swivel arm 38 by means of a piston-cylinder unit 41, so that the pressure roller 17 can be swiveled towards the reel 2 separately from the bearing shell 39.
• the piston-cylinder unit 42 which drives the swivel arm 38, can be position-controlled and the piston-cylinder unit 41, which serves to press the pressure roller 17, can be operated in a position-controlled and pressure-controlled manner.
• the other pressure rollers and deflection shells are held and driven similarly.
• the kinematic system of the separate pressure roller bearings on bearing levers 40 separated from the deflection shells 39 enables, due to the low mass, sensitive and responsive adaptation of the pressure rollers 17 to 19 when winding thin tapes at high speed while simultaneously protecting the tape surface.
