Roll handling system for a winder comprising a receiving unit having positioning means and a method therefor

Method for positioning of cores in a roll handling system, with

• a supply unit in order to transfer a plurality of cores to a receiving unit,
• wherein the receiving unit is movably assembled between the supply unit and a transfer station, between the transfer station and the supply unit a positioning device is provided,
• the receiving unit comprises a first contact surface with positioning means extending as a protrusion from the contact surface,
• the transfer station comprises a holding device, which is directly assembled at a winding shaft,
• wherein the following steps are comprised:
• transfer of the cores to the receiving unit so that a least a core is applied on a positioning means, wherein the at least one core comprises an inclined state at the contact surface of the receiving unit,
• movement of the receiving unit in the direction of the transfer station wherein during this movement the positioning device acts on the at least one core and the core leaves the inclined state and is pushed on the contact surface of the receiving unit, wherein a first positioning of the at least one core occurs.

A Roll handling system for a winder in which cores received from a supply unit wind with a material web to produce a plurality of rolls consisting of the cores in order to transfer the plurality of cores to a receiving unit,

• the receiving unit is movably assembled between the supply unit and a transfer station with which the cores are transferable to the winder and rolls are transferable from the winder to the transfer station;
• wherein the receiving unit comprises a first contact surface with positioning means in order to align the core at the receiving unit via a positioning device assembled between the supply unit and the transfer station;
• wherein the receiving unit comprises a second contact surface in order to receive the rolls;
• wherein
• the second contact surface is movable independently from the receiving unit.
