Definitions

  • the invention relates to a transport device for transporting a coil, the use of such a transport device, a coil processing system with such a transport device, and a method for transporting a coil.
  • a rolled product such as metal strip or metal wire
  • a coil i. H. in coiled form to be transported.
  • Such a bundle of a wound rolled product is also called a coil in technical circles.
  • a coil transport vehicle for the transport of a coil, for example, a coil transport vehicle can be used, which is equipped with a coil support on which the coil can be placed.
  • a coil in which the wound rolled product has a high strength and/or a high thickness, can tend to jump out of a coil support of a coil transport car or fall off the coil support, since the coil acts like a (spiral) spring due to its material rigidity. If a coil jumps open, there is a risk that people in the vicinity of the coil will be injured and/or system components will be damaged.
  • the coil can be closed with one or more straps after the rolled product has been wound up.
  • any straps that are present are removed in a separate strap-removal station upstream of the sampling station, there is a risk that a coil that tends to jump open will jump open during its transport from the strap-removal station to the sampling station.
  • a coil that tends to jump open if it is strapped (again) in a strapping station downstream of the sampling station, may jump open during its transport from the sampling station to the strapping station.
  • a transport device for transporting a coil with a coil transport carriage and a height-adjustable coil support according to the preamble of claim 1 is known.
  • a movable fixing device provides a height-adjustable clamping unit for pressing the coil to be transported against the coil support, the clamping unit being insertable at least partially into a coil eye of the coil.
  • One object of the invention is to enable a coil to be transported safely.
  • the transport device according to the invention for transporting a coil has a coil transport carriage.
  • the coil transport vehicle includes a chassis and a coil support, which is height-adjustable relative to the chassis.
  • the transport device according to the invention has a movable fixing device with a clamping unit for pressing the coil to be transported against the coil support, the clamping unit being height-adjustable relative to the coil support and being at least partially insertable into a coil eye of the coil.
  • a coil to be transported can be moved from one place to another, lying on the coil support of the coil transport car.
  • the moveable fixing device in particular its clamping unit, can be used to fix the coil in relation to the coil support during transport, i. H. to hold the coil in its position with respect to the coil support.
  • Pressing the coil to be transported against the coil support using the clamping unit makes it possible to form a non-positive connection between the coil and the coil support.
  • the coil By pressing the coil to be transported against the coil support, the coil can be reliably secured against tipping over and/or against jumping open.
  • the transport device can thus be used in particular to transport coils that tend to jump up and/or tip over, the transport device not being restricted to the transport of such coils.
  • the transport device is not limited to transporting coils of a predetermined diameter, but can transport coils of different diameters.
  • a coil to be transported can be fixed with respect to the coil support using the clamping unit, it is also not necessary for the coil to be closed with one or more straps when it is being transported on the coil transport wagon - especially even if the coil tends to jump open .
  • the clamping unit With the help of the clamping unit it is also possible at a coil processing station to press the coil against a coil holder of the coil processing station. This enables the coil to be processed safely in/at the coil processing station, especially when the coil tends to spring open and is not strapped with a strap.
  • the coil transport car is preferably a rail-guided car.
  • the coil transport carriage can be moved on rails in a preferred manner.
  • the coil transport carriage is equipped with a drive unit for driving the coil support, in particular for raising and lowering the coil support.
  • This drive unit can, for example, be a lifting cylinder, in particular a hydraulic lifting cylinder. Hydraulic jacks have the advantage that they are generally compact and robust.
  • the fixing device has its own drive unit for driving the clamping unit, in particular for raising and lowering the clamping unit.
  • This drive unit can be, for example, a lifting cylinder, in particular a hydraulic lifting cylinder.
  • the clamping unit can be moved linearly.
  • the coil transport carriage can, for example, have a guide element, in particular a sliding guide, by means of which the clamping unit is mounted in a linearly displaceable manner relative to the coil support of the coil transport carriage.
  • a guide element can be part of the coil support or the chassis, for example, or it can be attached to the coil support or the chassis.
  • the clamping unit can be moved in a pivoting manner.
  • the clamping unit can have sections that can be pivoted relative to one another.
  • the fixing device in particular its drive unit for driving the clamping unit, is attached to the coil support or to the chassis of the coil transport vehicle. This enables a compact configuration of the transport device, since a separate carriage for the fixing device and said synchronization device can be dispensed with in this case. The movability of the fixing device can therefore be ensured in particular by the movability of the coil transport carriage.
  • the transport device preferably includes a synchronization device for synchronizing the movements of the clamping unit and the coil support.
  • This synchronization device is advantageously set up to control the drive unit for driving the clamping unit and the drive unit for driving the coil support in such a way that the coil support and the clamping unit move synchronously, i. H. move with the same speed and the same direction of movement.
  • the synchronization device can have one or more position sensors for monitoring the positions of the clamping unit and/or the coil support.
  • the clamping unit is preferably moved by the same height as the coil support when the coil support is raised/lowered, unless the clamping unit is raised/lowered relative to the coil support by the drive unit of the fixing device.
  • a synchronization device for synchronizing the movements of the clamping unit and the coil support can be dispensed with in this case.
  • the clamping unit has a clamping section and a base section connected to the clamping section.

  • the clamping section preferably extends in the longitudinal direction of the coil support.
  • the previously mentioned drive unit of the fixing device can be at least partially integrated into the clamping unit, in particular into the base section of the clamping unit.
  • the clamping unit can be lowered at least partially, in particular at least a part of its clamping section, into the coil support.
  • the clamping unit can be sunk into the coil support in particular when it is not necessary to press the coil to be transported against the coil support, for example because the coil neither tends to jump up nor tip over. In such a case, there is no need to insert the clamping unit into a coil eye of the coil to be transported or to press the coil against the coil support, which can make the coil transport more time-efficient overall.
  • the coil support has a recess in which the clamping unit can be lowered at least partially. It is particularly preferred if the clamping unit can be lowered into the coil support in such a way that its upper side is flush with the upper side of the coil support.
  • the clamping unit is equipped with a friction reduction unit.
  • the friction reduction unit advantageously serves to reduce frictional resistance between the coil and the clamping unit, in particular when winding and/or unwinding the coil.
  • the friction reduction unit can have, for example, one or more rollers as friction reduction means.
  • the rollers are rotatably mounted.
  • the friction reducing unit is arranged on the underside of the clamping portion of the clamping unit, in particular on that end of the clamping portion remote from the base portion of the clamping unit.
  • the clamping unit can have a rounded contact surface for pressing onto the coil eye. Due to the rounding of the contact surface of the clamping unit, its contact pressure (compared to a flat contact surface) can act on a larger area of the coil to be transported. As a result, the coil can be damaged by the clamping unit, e.g in the form of indentations, can be avoided or at least reduced.
  • the rounded contact surface is preferably located on the underside of the clamping section of the clamping unit, in particular on that end of the clamping section which is remote from the base section of the clamping unit.
  • the coil support can have several support prongs on which the coil can be placed. It is advantageous if the support prongs are bevelled towards the longitudinal center plane of the coil support. In this way, the support prongs can stabilize the coil to be transported on the coil support.
  • the longitudinal center plane of the coil support means a plane parallel to the longitudinal direction of the coil support, with respect to which the coil support is mirror-symmetrical.
  • the wording that “the support prongs are beveled towards the longitudinal center plane of the coil support” can be understood to mean that the upper side of the respective support prong is oriented obliquely to the longitudinal center plane and faces the longitudinal center plane.
