The invention relates to a reel handling system for a winder (50), in which bobbins (1) with a material web (2) can be applied, with the result that a plurality of reels (3) which are wound on the bobbins (1) with a material web (2) are produced, having a feed unit (10), in order to transfer a plurality of bobbins (1) to a receiving unit (20), wherein the receiving unit (20) is arranged movably between the feed unit (10) and a transfer station (60), by way of which receiving unit (20) bobbins (1) can be transferred to the winder (50) and reels (3) can be transferred from the winder (50) to the transfer station (60), wherein the transfer station (60) has a holding device (61), to which a winding shaft (62) is fastened releasably on one side, wherein the bobbins (1) can be pushed onto the winding shaft (62) during the movement of the receiving unit (20) in the direction of the transfer station (60).

The invention relates to a roll handling system for a winder (50) in which cores (1) are applicable each with a material web (2) so that a plurality of rolls (3) consisting of cores (1) wound with the material web (2) are produced with a supply unit (10) in order to transfer a plurality of cores (1) to a receiving unit (20), wherein the receiving unit (20) is movably assembled between the supply unit (10) and a transfer station (60) with which cores (1) are transferable to the winder (50) and rolls (3) are transferable from the winder (50) to the transfer station (60). According to the invention the receiving unit (20) comprises a first contact surface (23) with positioning means (24) in order to align the core (1) at the receiving unit (20) via a positioning device (80) assembled between the supply unit (10) and the transfer station (60).

A method for storing cardboard tubes (2) in a storing unit according to the present invention comprising the following steps: providing a storage unit with an input section for the tubes (2), a storage section (AC) comprising a plurality of storing planes (13), an output section for the tubes (2), transfer means (3) for transferring the tubes (2) from the input section to the storage section, and discharge means for conveying the tubes (2) from the storing section to the output section; providing a plurality of cardboard tubes (2) in the input section (E) of said storage unit; transferring the tubes (2) from the input section of the storage unit to the storage section; storing a plurality of tubes (2) in said storage section (AC); transferring the tubes (2) from said storage section (AC) to said output section. The step of transferring the tubes (2) from said input section to said storage section involves more tubes (2) simultaneously, whereby a plurality of tubes (2) are transferred from said input section simultaneously on a plurality of storing planes (13) of the storage section (AC).

An automatic core loading system for loading a plurality of cores onto a rewind shaft includes a populating conveyor and a loading conveyor. The populating conveyor is configured to grab and move each core from a core source with the plurality of cores to a loading point for the loading conveyor one core at a time. The loading conveyor is configured to grab and move each of the cores from the populating conveyor at the loading point and move each core to a set position with a pre-determined or electronically measured gap between each core on the rewind shaft. Wherein, the automatic core loading system is configured to automatically load the plurality of cores onto the rewind shaft with the pre-determined or electronically measured gap between each core to match slit widths and spacing between a slit web of material.

A method for replacing a working component in an automatic machine has a mapping phase and a working phase. The mapping phase involves defining a first reference point fixed relative to the automatic machine and a position in machine of the working component. The working phase involves: stopping the automatic machine (2); starting a procedure of configuration change preparing the automatic machine for a withdrawal of the working component; detecting the first reference point; determining the position in machine of the working component; picking up the working component from the position in machine by means of a gripping device; releasing the working component in a storing position; picking up a replacement working component from a stocking position by means of the gripping device; positioning the gripping device at the position in machine; and inserting and fixing the replacement working component in the position in machine.

A device is for automatically introducing a reinforcing sheet into a coreless coil applicable to a coreless winding machine. The winding machine includes such a device. In particular, a device is for introducing a reinforcing paper sheet into a coreless roll being wound with a continuous strip material by a coreless winding machine. The device includes a feeding tray for paper sheets, a feeder of the paper sheets taken from the feeding tray, and an introduction member of a paper sheet loaded into a roll being wound in the winding machine.

The disclosed subject matter provides a mandrel feeding device and a battery winder. The mandrel feeding device has a dispensing station, an adjusting station, an adhesive application station, a transferring unit, a dispensing unit, a feeding unit configured for gripping a mandrel on the transferring unit and transferring gripped mandrel to a winding mechanism.
