Abstract
System for handling cardboard reels to feed machines that produce cardboard tubes, comprising a station (P) for picking up the reels configured to receive a stack (2) of overlapping cardboard reels (1), a station (U) for unwinding of the reels comprising at least one unwinding unit (UU), and handling means (D) for moving the reels (1) along a predetermined path between the reel pick-up station (P) and the unwinding station (U). The reel handling means are provided with an additional reversible device for hooking the reels to the handling means themselves.
Claims18
A plant for handling cardboard reels for feeding tube-forming machines, comprising a reel pick-up station (P) configured to receive a stack (2) of cardboard reels (1) superimposed according to a predetermined orientation, an unwinding station (U) for unwinding the reels (1) comprising at least an unwinding unit (UU) adapted to support the reels to be unwound in an unwinding position, in the unwinding station (U) being also provided splice means configured to splice a tail portion (TY) of a running out reel (1Y) with a new reel (1W) to continuously unwind the reels progressively arranged in the unwinding station (U), and handling means (D) for moving the reels (1) along a predetermined path comprised between the reel pick-up station (P) and the unwinding station (U), characterized in that said reel handling means are configured and controlled for picking up the reels from the stack in the reel pick up station (P), moving the reels along said path, and positioning the reels in the unwinding station, by keeping the initial orientation of the reels constant with respect to the stack (2) at least in the step of picking up the reels from the stack (2) and in that said handling means of the reels are provided with an additional reel engaging/disengaging device associated with the reel handling means and adapted for reversible hooking of the reels to the same handling means.
A process for handling cardboard reels for feeding tube-forming machines, comprising the arrangement of a reel pick-up station (P) configured to receive a stack of cardboard reels (1) superimposed according to a predetermined orientation, an unwinding station (U) for unwinding the reels (1) comprising at least one unwinding unit (UU) adapted for supporting the reels to be unwound in an unwinding position, splice means being also provided in the unwinding station (U) configured to splice a tail portion (TY) of a reel (1Y) in the run-out phase with a new reel (1W) to continuously unwind the reels progressively arranged in the unwinding station (U), and handling means (D) for moving the reels (1) along a predetermined path between the reel pick-up station (P) and the unwinding station (U), characterized in that the pick-up of the reels from the stack arranged in the pick-up station (P), the movement of the reels along said path, and the positioning of the reels in the unwinding station are executed by keeping constant the initial orientation of the reels in relation to the stack (2) at least during the step of pick- up the reels from the stack (2) and in that the handling means of the reels are provided with an additional reel engaging/disengaging device associated with the reel handling means and adapted for reversible hooking the reels to the same handling means.
