Abstract
Apparatus for winding at least one strip of material for the production of electrical energy storage devices, comprising: a rotatable winding core, configured to grip the strip and actuatable to carry it in rotation and thus form a winding; a feed unit to feed the strip of material; and a handling device configured to move the winding core at least between a winding station, at which the winding core is configured to receive the strip in feeding, grip it and wind it about the rotation axis, and a second station; wherein the handling device is configured to move the winding core from the winding station to the second station during the winding.
Claims13
Apparatus (1) for winding at least one strip (2, 3) of material for the production of electrical energy storage devices, the apparatus (1) comprising:
- a winding core (5) rotatable around a rotation axis (R), configured to grip said strip (2, 3) and actuatable to carry in rotation the gripped strip (2, 3) and thus form a winding (4) about the rotation axis (R) from a predetermined-length portion of said strip (2, 3);
- a feed unit (6, 7, 8) to feed the strip (2, 3) of material to the winding core (5);
- and
- a handling device (20) configured to move the winding core (5) at least between a winding station (A), at which the winding core (5) is configured to receive the strip (2, 3) in feeding, grip it and wind it about the rotation axis (R), and a second station (B, C), at which the apparatus (1) is configured to perform on the formed winding (4) a further process successive to the winding of the strip;
- wherein the handling device (20) is configured to move the winding core (5) from the winding station (A) to the second station (B, C) during the winding about the core (5) of at least part of said predetermined-length portion;
- the apparatus comprising a fixed frame (13), wherein the feed unit (6, 7, 8) is mounted to the frame (13) in a movable manner;
- and wherein the apparatus further comprises an actuator configured to drive a movement of the feed unit (6, 7, 8) relative to the frame (13), during the movement of the winding core (5) from the winding station (A) to the second station (B, C), in order to adjust the positioning of the strip (2, 3) in feeding to the core (5) according to a trajectory (T) of this latter between the winding station (A) and the second station (B, C).
Method for winding a strip (2, 3) of material for the production of an electrical energy storage device, the method comprising the steps of:
- a) feeding the strip (2, 3) of material to a winding core (5) rotatable around a rotation axis (R);
- b) gripping the strip (2, 3) by means of the winding core (5);
- c) rotating the winding core (5) to carry in rotation the gripped strip;
- d) winding, by means of step c) of rotating, the gripped strip (2, 3) about the rotation axis (R), thus forming a winding (4) from a predetermined-length portion of said strip (2, 3);
- e) moving the winding core (5) from a winding station (A), at which steps b) of gripping and c) of rotating are carried out, to a second station (B, C), at which a further process successive to the winding of the strip (2, 3) is carried out on the formed winding (4);
- wherein step e) of moving is performed during at least part of step d) of winding;
- the method further comprising the step of:
- f) adjusting, during step e) of moving, a positioning of the strip (2, 3) in feeding to the winding core (5) as a function of a trajectory (T) of the winding core (5) between the winding station (A) and the second station (B, C).
