Definitions

  • the invention relates to a winding and / or unwinding reel for rolled strip with a drum, which consists of a plurality of segments which can be spread, which are supported with wedge-shaped sliding surfaces against a reel shaft rotatably mounted in a reel housing, with a punch guided in the reel shaft, which is guided by means of a Connection flange is connected to the drum segments, wherein an actuator can cause a relative, axial displacement between the reel shaft and the punch connected to the reel segments, which causes a spreading movement of the segments, as well as with an insertion and removal of the reel drum relative to the coil and / or the shift drive effecting the belt center control.
  • EP-PS 004854 already discloses a roll coiler of the generic type. This has a non-rotatable actuator connected to the reel shaft, which must always be supplied with pressure medium during operation in order to keep the segments in the spread position. This means that pressure-sensitive rotary feeders that are prone to failure and cost are necessary.
  • the entire reel housing In order to be able to carry out the entry stroke into the coil (preferably with double cone coils) and to compensate for the strip center offset, the entire reel housing must be moved on rails or other guides in the direction of the reel shaft in this known rolled strip reel.
  • the sliding drive must be dimensioned so that the heavy reel housing together with reel, actuator, drive motor, clutch and Gear can be moved exactly. This necessitates expensive guides with which these large loads can be handled precisely. In addition, correspondingly large and expensive sliding drives are necessary.
  • the invention has for its object to improve a generic rewinding and / or unwinding reel in such a way that simple and easy despreading, optimal retraction and extension of the reel drum into one with small and inexpensive drives without the need to supply pressure medium rotating parts Coil or from the same as well as a secure adjustment of the belt center are guaranteed.
  • the reel shaft is axially displaceably mounted in the stationary reel housing
  • the actuator has a piston-cylinder unit which is non-rotatable but axially displaceable relative to the stationary reel housing for depressurizing the reel shaft
  • a compression spring as is known per se, always keeps the segments in a spread state
  • the displacement drive consists of a piston-cylinder unit, by means of which the reel shaft can be axially displaced.
  • the drives can be kept small and thus inexpensive, since it is no longer the entire reel housing that is axially displaced, but only the reel shaft. With the small ones pushing loads, a very precise retraction and extension of the reel drum as well as exact adherence to the center of the belt is cost-effectively guaranteed. Pressure medium feeds to rotating parts are superfluous due to the use of segments which are always held under tension by spring force.
  • reel shaft is arranged in a rotatable, axially non-displaceable hollow drive shaft axially displaceably and by means of wedges engaging in the groove, and that the hollow drive shaft is provided with a gear in which a drive gear of a fixed gear engages.
  • the actuator expediently has a pot-like extension, the edge of which encompasses the end of the reel shaft facing away from the reel drum and is mounted at this end in such a way that practically no moments are transmitted, but there is non-positive connection in the axial direction, so that the axial rotation takes up the reel shaft Coupling is effected, and that the displacement drive acts on the actuator and acts on the reel shaft via this.
  • the actuator is axially displaceable relative to the reel housing and the displacement drive is arranged stationary.
  • the reel 1 shows a reel 1 which is suitable both for winding up and unwinding rolled strip.
  • the reel 1 has a reel housing 3 mounted on a base frame 2.
  • a hollow drive shaft 6 is rotatably axially immovable.
  • a reel shaft 7 designed as a multi-spline shaft is guided so as to be axially displaceable in a rotationally fixed manner.
  • the wedges 8 of the reel shaft 7 engage in corresponding grooves 9 in the hollow drive shaft 6.
  • wedge-shaped sliding surfaces 10 are arranged, on which the segments 11 of the reel drum 12 are supported.
  • a punch 13 is guided in the reel shaft 7. This guide allows a relative axial displacement between the reel shaft 7 and the punch 13.
  • the punch 13 is connected to the segments 11 via a connecting flange 14.
  • the reel shaft 7 At the end of the reel shaft 7 facing away from the reel drum 12, the reel shaft 7 has an inner diameter that exceeds the outer diameter of the punch 13.
  • a compression spring 15 is embedded, which is supported on the one hand on the reel shaft 7 and on the other hand on a head 16 of the punch 13. By means of spring force, the segments 11 are held in the spreading position by the axially fixed punch 13 via the reel shaft 7.
  • the rotary drive of the reel drum 12 takes place from the motor 17 via the clutch 18, the gear 19, the gear 20 fixed on the drive hollow shaft 6 and the reel shaft 7.
  • the reel drum 12 can be despread by axially displacing the reel shaft 7 against the force of the compression spring 15.
  • the punch 13 should be axially fixed. This has the advantage that the segments 11 are also axially fixed during the spreading or de-spreading process. This means that there is no additional belt center offset when changing the coil.
  • the rotationally fixed but axially displaceable actuator 21 effects the de-spreading action on the reel shaft 7.
  • the actuator 21 is connected to the base frame 2 via a slide 22.
  • the actuator 21 consists of the cylinder 23 in which a piston 24 is guided. At the free end of the piston rod 25, a head 26 is provided which faces the head 16 of the plunger 13.
  • a pot-like extension 27 is mounted on the cylinder 23, the edges of which are connected to the end of the reel shaft 7 facing away from the reel drum 12 by means of bearings 28 which absorb rotary movements and which are non-positively coupled in the axial direction.
  • the piston rod 25 continues from the end facing away from the head 26 beyond the piston 24 and the cylinder 23 and there forms the point of application for the piston rod 29 of the the base frame 2 fixedly mounted sliding drive 30.
  • the reel drum 12 In the operating position (FIG. 1), the reel drum 12 is driven by the motor 17.
  • the head 26 on the actuator 21 is separated from the head 16 of the stamp 13.
  • the reel drum 12 is tensioned by the compression spring 15.
  • the displacement drive 30 can act on the reel shaft 7 and the punch 13 via the axially displaceable actuator 21 in such a way that the reel drum 12 is aligned precisely with the center of the band during operation without a spreading movement being carried out.
  • the motor 17 is stopped in the despread position (FIG. 2).
  • the reel shaft 7 is to be moved axially toward the actuator 21 via the pot-like extension 27.
  • the displacement drive 30 is acted upon in the opposite direction to the actuator 21.
  • the displacement drive 30 is displaced axially to the extent that the cylinder 23 of the actuator 31 is displaced.
  • the reel shaft 7 and the punch 13 remain axially at rest for the time being.
  • the displacement drive 30 is switched off.
  • the plunger 13 remains at rest, while the reel shaft 7 is moved axially toward the actuator 21 when the actuator 21 is further acted upon.
  • the relative displacement between the reel shaft 7 and the punch 13 causes the segments 11 to despread.
  • FIG. 3 shows the reel drum 12 extended from the coil 31.
  • the actuator 21 is still in the despread position, while the displacement drive 30 has axially displaced the actuator 21 on the carriage 22. Together with the actuator 21, the reel shaft 7, the punch 13 and thus the reel drum 12 were pulled axially out of the coil 31 via the pot-like extension 27.
  • the winding and / or unwinding reel according to the invention is outstandingly suitable for the operation of double-cone reels with belt center control.
  • For the construction of a double cone reel only two winding and / or unwinding reels according to the invention have to be mounted in mirror image to one another. It is also possible to design one of the double cone halves without the rotary drive 17 to 20.
