PROCESS AND DEVICE FOR LOADING, UNLOADING AND CONTINOUS WINDING OF PRODUCT ON A REEL
FIG2 shows an expanded side view of the transport means in a forward position
Transport means (15) are used to move the movable reel (4) in the direction of the first shaft (6), in one direction or another, between the mobile station (1) and a loading position, as indicated by the horizontal double arrow of FIG2. As indicated above, the gripping means (10) take and release the movable reel (4) from one single side, called loading side, which is the side closest to the mobile station (1), specifically to the first shaft (6). According to a preferred embodiment, shown in the figures, the gripping means (10) are assembled on the first shaft, preferably on the end of the first shaft (6), for example on a head (11), to be able to be inserted in a central axial gap (7) of the movable reel (4). Preferably, the gripping means (10) can include extendable and retractable clamps, for example in a pneumatic or hydraulic manner, as schematically illustrated by means of vertical double arrows in FIG2.

['1. A process for loading, unloading and winding of product on a reel, that comprises the following steps: a) arranging in a loading position at least one movable reel (4), already loaded with a first product (2),facing a first shaft (6) of a mobile station (1) of a device for loading, unloading and winding of product on reels, wherein a loading side of the movable reel (4) closer to the first shaft (6), faces the first shaft (6); b) transporting gripping means (10) from the mobile station (1) by means of transport means (15); c) gripping the movable reel (4), from one single side, the loading side, with the gripping means (10); d) the movable reel (4) being gripped, moving, by means of the transport means (15), the gripping means (10) together with the movable reel (4) towards the mobile station (1) in the direction of the first shaft (6); e) assembly the movable reel (4) on the first shaft (6) in the mobile station (1), characterized in that  it further comprises the following steps: e1) hooking the first product (2) of the movable reel (4) on a non-movable reel (9) next to the movable reel (4), and start to transfer the first product (2) from the movable reel (4) to the non-movable reel (9) until completely emptying the movable reel (4); and e2) continuously providing a second product (3) on the movable reel (4), to simultaneously transfer the first product (2) back to the movable reel (4) from the non-movable reel (9) ; and f) the gripping means (10) being holding the winded movable reel (4) on the loading side, actuate the transport means (15) to move the gripping means (10) together with the movable reel (4) toward the loading position.']
