Definitions

  • the present invention relates to a reel for winding strip-shaped material on a driven by a drive device coiler mandrel, which is provided for radially prestressed receiving a coil with Sp DrISSsegmenten, which are provided on its inside with a wedge surface arrangement and are arranged on a spreader on their Outside is provided with a wedge surface arrangement (see for example the DE 27 23 964 A1 on which the preamble of claim 1 is based).
  • Reels of the type mentioned are used, for example, in strip production in a rolling process, where regularly in a one-way or Reversier ceremonies the tape unwound with a defined strip tension of a first reel, moved through a nip of a roller device and wound on another reel with defined strip tension is then to be wound on the reel in a subsequent rolling pass after repeatedly repeated passage through the roller means until the desired rolled strip thickness is reached.
  • Starting material for such a rolling process is a rolled strip with a relatively large thickness, the must be taken on the first reel at the beginning of the rolling process and must be removed after completion of the rolling process as a rolled strip of the desired thickness of the reel.
  • reels that are provided with a small diameter coiler mandrel and Sp Sonsegmenten with relatively small surface area, which serves as a contact surface for transmitting the torque must be transmitted to generate the necessary high radial clamping forces of the expansion tensile forces with the tie rod, in particular in connection can cause a pull bar break due to the exceeding of the permissible voltage values with the stress acting on the drawbar with rotating reel shaft due to continuous alternating bending.
  • the present invention has for its object to provide a reel that allows safe torque transmission between the coiler mandrel and a coil with a comparatively simple construction of the coiler mandrel.
  • the invention has the features of claim 1.
  • a reel is provided with a coiler mandrel having a spreading device which is arranged radially between the expansion segments and a reel shaft and by means of a drive device axially against the expansion segments and the reel shaft is displaceable, wherein the drive means arranged on the reel shaft piston Cylinder unit whose piston for spreading the Sp Sonsegmente via a formed in the reel shaft axial fluid supply can be acted upon with a pressure medium and connected to transmit an axial displacement via a driver with the spreading device.
  • the drawbar known from the prior art which interacts with the spreading device via a driver, is replaced by an axially acting piston-cylinder unit which, via the piston, generates the force necessary for generating the radial clamping forces of the expanding segments transfers the expansion segments.
  • an axially acting piston-cylinder unit which, via the piston, generates the force necessary for generating the radial clamping forces of the expanding segments transfers the expansion segments.
  • the function of the conventional drawbar is replaced by the fluid supply and connected to the fluid supply piston-cylinder unit.
  • the reel mandrel of the present invention designed reel, which has only an axially acting piston-cylinder unit for transmitting the tensile forces on the driver, in comparison to the known, provided with a hydraulically operated spreader coiler mandrel a comparatively simple construction.
  • This structurally simple construction also makes it possible to retrofit a reel mandrel conventionally designed with a pull rod acting on the driver by retrofitting it with a fluid supply and an axially acting piston-cylinder unit to form a coiler mandrel of a reel designed according to the invention.
  • radial return of the expansion segments can be provided on the reel mandrel, in particular at one axial end of the coiler mandrel, for example, a spring means, so that a fluid supply, which acts to act on a single-acting piston, which cooperates with the driver such that the expansion segments radially be moved to the outside, in principle, is sufficient for the realization of a reel according to the invention.
  • the radial return of the expansion segments can then be done after switching off the pressurization of the piston via the restoring forces of the prestressed spring device.
  • the fluid supply has a coaxial channel arrangement with an inner channel and an outer channel arranged concentrically to the inner channel, and the piston of the piston-cylinder unit is designed as a double-acting piston.
  • both a radially outward movement of the expansion segments and a radially inwardly directed movement of the expansion segments can take place via the pressure medium acting on the piston-cylinder unit.
  • a structurally particularly simple embodiment is possible if the inner channel is formed by an inserted into an axial bore of the reel shaft and the outer channel channel formed between the sewer pipe and a bore wall of the axial bore annular channel, such that an application of a piston surface of the piston via the sewer pipe and an impact of an opposing piston surface of the piston takes place via the annular channel.
  • a cylinder space of the piston-cylinder unit is formed by a bore section of the axial bore of the reel shaft.
  • the piston is guided with a guide member on a sewer pipe end of the sewer pipe, wherein the guide member is provided with a fluid passage for forming an axially penetrating the piston and exiting in the piston surface for pressurizing the piston surface pressure line.
  • the guide member is provided with a fluid passage for forming an axially penetrating the piston and exiting in the piston surface for pressurizing the piston surface pressure line.
  • the formed in the guide part fluid channel is used to form a telescopic extension of the sewer pipe, so that regardless of the relative position of the piston relative to the sewer pipe, a pressure medium supply is ensured on a piston surface for pressurizing the piston.
  • the opposing piston surface is acted upon by the opening into the cylinder chamber of the piston-cylinder unit annular channel of the channel arrangement with pressure medium, the piston serves not only to form a telescopic extension of the inner channel formed by the sewer pipe, but also to extend the External channel of the channel arrangement.
  • the piston opposite the guide part preferably has an actuating part led out of the cylinder space guided in the reel shaft, on which the driver for the connection to the spreading device is arranged, so that a direct coupling of the driver to the piston is possible without the use of special coupling elements.
  • Fig. 1 shows a coiler mandrel 10 with a reel shaft 11, which, in particular the Fig. 4 can be seen, is provided with three distributed over the circumference expansion segments 12, which form an expansion drum 13, which serves for torque transmission to a coil not shown here, the coil being disposed on a recorded by the expansion drum coil or directly on the expansion drum can.

  • FIG. 4 shows the cross section of the coiler mandrel 10 in a despread state in which the spreader bars 15 in their in Fig. 1 drawn position.
  • Fig. 5 shows the cross section of the coiler mandrel 10 in a spread state in which the expansion strips 15 from the in Fig. 1 drawn position shifted to the left.
  • a piston-cylinder unit 21 is provided on a central axis 20 of the reel shaft 11 with a piston 22, which via an associated with the piston 22 driver 23 an axial movement of the Piston 22 transmits to the Sp Dahln 15.
