Definitions

  • the present invention relates to a device for opening a rolled strip coil with a pressure roller arranged in a height-adjustable manner on a frame device for contacting a coil circumference of the rotating rolled strip coil and a strip beginning detachment device arranged in a height-adjustable manner on the frame device, the frame device being provided with a strip beginning forming device.
  • Rolled strip coils consist of a spirally wound rolled strip, so that the coil must be secured during handling to maintain the coil shape by fixing the rolled strip end and the rolled strip start.
  • the outer end of the rolled strip is often welded to an adjacent winding on the outer coil circumference.
  • coils without spools are fixed to the inner circumference of the coil with a weld seam fixation of the end of the rolled strip.
  • a so-called “coil preparation” is therefore regularly carried out, in which the rolled strip coil is "opened", i.e. the fixing of the beginning of the rolled strip and, if necessary, the end of the rolled strip is released.
  • a set of straightening rollers is provided in an infeed device upstream of the rolling mill, which sets the rolled strip with an alternating bending stress and which, in order to facilitate the introduction of the beginning of the rolled strip into the set of straightening rollers, is regularly preceded by a bending device which forms a so-called "rolled strip ski” at the beginning of the rolled strip when introducing the beginning of the rolled strip, such that the edge of the rolled strip at the beginning of the rolled strip has a curvature directed upwards like a ski shovel.
  • coil preparation has required the use of manually operated tools and causes additional non-productive times in the rolling process, with corresponding effects on the productivity of the rolling mill.
  • the formation of the "rolled strip ski” takes place in a bending device arranged on the infeed device, as a result of which the overall length of the rolling plant is increased.
  • the JP S56 45214 A shows a device for opening a rolled strip coil, and forms the basis for the preamble of claim 1.
  • the present invention is based on the object of proposing a device which enables the coil preparation to be largely automated and a rolled-strip ski to be formed independently of the configuration of the rolling plant.
  • the device according to the invention for opening a rolled strip coil is arranged with a height-adjustably arranged pressure roller on a frame device for bearing against a coil circumference of the rotating rolled strip coil and a height-adjustably arranged on the frame device Provide beginning of tape detaching device, wherein the frame device has a beginning of tape forming device.
  • the device according to the invention not only enables the rolled strip coil to be opened with the strip start detaching device, but also allows the rolled strip ski to be formed independently of the rolling plant by means of the strip start shaping device.
  • the device according to the invention can be arranged both in the rolling plant, in particular in an uncoiling device, and at a location independent of the rolling plant, so that the coil preparation of a rolled strip coil can take place while a previously opened rolled strip coil is already in the uncoiling device of the rolling mill is located.
  • the formation of the rolled strip ski is made possible in cooperation with the initial strip forming device on the rotating rolled strip coil.
  • the stand device is provided with a drive device for driving the rolled strip coil in rotation, so that no drive device independent of the stand device is required for rotating the rolled strip coil.
  • the pressure roller is designed as a drive device for driving the rolled strip coil in rotation.
  • the device according to the invention can be operated in combination with a conventional coil car on which the rolled strip coil is located.
  • the rotary drive can be effected by support rollers which are arranged on the coil carriage and receive the rolled strip coil.
  • the rotational drive can take place by means of the drive of the uncoiling device.
  • the beginning-of-strip forming device has a beginning-of-strip lifter and a beginning-of-strip hold-down device, which are arranged following the pressure roller in the drive direction and at a distance from one another, so that depending on the distance between the beginning-of-strip lifter and the beginning-of-strip hold-down device and the lifting speed of the beginning-of-strip lifter in relation to the drive speed of the rolled strip coil the formation of the rolled strip ski can take place.
  • the leading-edge hold-down device is arranged on the frame device so that it can be adjusted between an operating configuration and a non-operating configuration in its position relative to the pressure roller, the leading-edge hold-down device can be arranged in the immediate vicinity of the pressure roller and removed from the coil circumference when the leading-edge detaching device is in operation, so that, despite a compact arrangement, a collision between the tape beginning detaching device and the tape beginning hold-down device is excluded.
  • the hold-down device for the beginning of the tape preferably has a pivoting lever which is arranged on the frame device and can be pivoted about a roller axis of the pressure roller and has a support roller arranged on the pivoting lever, so that to transfer the hold-down device for the beginning of the tape from the non-operating position to the operating position, only a comparatively short pivoting path has to be carried out, during which the Roller axis of the pinch roller is pivoted.
  • the strip start lifter preferably has a lifting bar that is height-adjustable relative to the frame device and has at least one lifting bar element, which has a preferably wedge-shaped contact edge for contact with a strip leading edge of the rolled strip coil is provided. It is thus possible to adapt the positioning of the lifting bar to the diameter of the rolled strip coil, with the lifting bar allowing penetration into a winding gap formed between the leading edge of the strip and the circumference of the coil after actuation of the strip start detachment device.
  • the contact edge is wedge-shaped, so that at the same time as the contact edge penetrates into the gap at the beginning of the tape, the gap at the beginning of the tape widens.
  • the lifting strip element has a ramp surface arranged between an impact surface and the contact edge, during the penetration of the contact edge into the winding gap with progressive rotational movement of the rolled strip coil through the ramp surface, a defined guidance of the strip leading edge against the impact surface with a radially outward deflection of the strip leading edge is formed of a rolled strip ski allows.
  • the lifting strip element is preferably provided with an adjustment device for setting an angle of attack formed between the run-on surface and the leading edge of the belt, so that by setting the smallest possible angle of attack it is possible to prevent the beginning of the belt from piling up on the run-on surface.
  • the lifting bar element can be pivoted about its longitudinal axis and fixed in the pivoted position by means of the adjustment device.
  • the lifting strip element is preferably provided at the contact edge with a nozzle arrangement for impinging the leading edge of the strip with a flow defined in the direction.
  • the nozzle arrangement can be used to flow against the edge of the rolled strip in a direction opposite to the direction of rotation of the rolled strip coil, so that in particular in the case of small rolled strip thicknesses, the formation or widening of the winding gap can be supported.
  • the lifting bar element is arranged at the lower end of a lifting device arranged on the frame device, so that the lifting bar element can be moved radially outwards from the rolled strip coil into a non-operating configuration by means of the lifting device, and the start of strip detachment device can therefore be used to open the rolled strip coil in the immediate vicinity to the pinch roller.
  • the lifting bar element can be moved into its operative configuration for forming the rolled strip ski without a significant rotational movement of the rolled strip coil being necessary. Both the beginning-of-strip detaching device and the beginning-of-strip reshaping device can therefore be used when the rolled strip coil has an essentially identical rotational position.
  • the lifting device is preferably designed as a lifting cylinder arrangement with at least one lifting cylinder, which is arranged on a frame crossbar arranged parallel to the lifting bar element on the frame device.
  • the start-of-strip detaching device has two severing devices whose spacing can be changed, so that the positioning of the severing devices at the connection points between the leading edge of the strip and the circumference of the coil can be adjusted as simply as possible.
  • the separating devices have separating chisels provided with a vibration device for separating a respective strip fixation formed in a winding surface of the rolled strip coil on the coil circumference.
  • the separating chisels are designed as compressed air chisels.
  • the frame means is pivotally mounted on a frame base.
