Definitions
- the invention relates to an expandable reel mandrel.
- reel arrangements which often consist of a carousel reel, i.e.
- two horizontally and parallel to each other spreadable reel mandrels are provided on a drum-shaped support frame arranged to be driven in rotation about a common axis. Exemplary designs for this are described in DE 195 43 046 A1 or DE 197 58 106 A1.
- the beginning of the band of a band to be wound is first inserted into a clamping slot of the reel dome and clamped (DE 42 07 041 C1).
- the remaining strip is then wound up, with the reel mandrel being spread out in order to hold the first strip layers firmly on the mandrel.
- the mandrel is reduced in diameter so that the coil can be pushed off the mandrel.
- Reel assemblies are not only used for reeling, but also for supplying a processing system with strip material.
- a finished coil is pushed onto the reel mandrel and - after the dome has been spread to clamp and hold the coil - the strip is pulled off and fed to a rolling mill, for example.
- the spreading reel mandrel determines the inside diameter of the coil during reeling, this can be very different in the case of delivered coils, so that problems can arise in holding a coil for unwinding on the reel mandrel.
- segments that can be placed on the coiler mandrel in these cases. However, these had to be attached to the mandrel for fixation, for example screwed on.
- Such a cover results in a certain increase in the mandrel diameter, but primarily serves to protect the ends of the strip, so that they are pressed into the elastomer material and do not appear in the adjacent layers of the coil.
- the invention is therefore based on the object of creating a reel mandrel, the diameter adjustment of which is possible to a greater extent with short changeover times.
- an expandable coiler mandrel which is characterized by a sleeve which can be pushed onto the mandrel and which consists of individual ring segments which are connected to one another by tension springs.
- the sleeve preferably consists of four such ring segments, the tension springs being arranged between the circumferential end of one and the circumferential beginning of the other ring segment.
- the ring segments that are kept together to form a sleeve in this way are easy to handle, ie they can be placed together for assembly on a pallet truck and then pushed by this over the mandrel. An additional indoor crane is not required.
- the mandrel is then reduced in diameter so that the sleeve can be removed.
- a diameter expansion of the dome can not only be achieved more safely because the assembly and disassembly is carried out by the - already present - pallet truck, but the whole process is also much faster, so that the rolling mill operation is not interrupted or only briefly must become.
- Another advantage is the relief of the operating personnel.
