Abstract
A method and device for feeding and changing reels on a manufacturing machine, whereby reels of strip material arranged side by side are fed successively into a first operating position substantially coplanar to a second operating position wherein the strip material is unwound normally. Each reel is supported in the second position by an arm which, as the reel in the second position runs out, releases the core of the empty reel, and picks up the reel in the first position; which reel has already been rotated, in the first position, by an unwinding device designed to feed the strip material on the reel in the first position at the same speed as the strip material on the reel in the second position.
Claims13
A device for feeding and changing reels (2) of strip material (5) on a manufacturing machine (4), characterised by the fact that it comprises a storage fixture (6) for said reels (2);
- means (8, 21) for successively feeding said reels (2) along said storage fixture (6), in a direction substantially parallel to their axis (9), and so as to set a first (2a) of said reels (2) in a first given position (7) on said storage fixture (6);
- means (16, 17) for supporting said first reel (2a) in said first position (7) and in such a manner as to rotate about is axis (9);
- a transfer element (26) for successively transferring said reels (2) from said first position (7) to a second normal unwinding position (31) adjacent to said first position (7), said transfer element (26) being connectable in rotary manner to each said reel (2) for supporting the same in said second position (31);
- and means (32) for unwinding said strip material (5a) off said reels (2a, 2b) in said first and said second position (7, 31) at normal unwinding speed and along a given path.
A method of feeding and changing reels (2) of strip material (5) on a manufacturing machine (4), comprising:
- positioning a plurality of reels (2), containing wound strip material, on a storage fixture (6);
- moving a first (2a) of said reels (2) to a first position (7) by a feeding means (8, 21);
- supporting the first reel (2a) in the first position for rotation about its axis (9);
- mounting a second reel (2b), containing strip material (5b) to be unwound and supplied therefrom to a given path, on a transfer element (26) located at a second position (31);
- unwinding strip material (5b), at a predetermined normal speed, from the strip-supplying second reel (2b) located on the transfer element 26 and at the second position (31), which is occupied successively by second reels (2b) and feeding the unwound strip material (5b) along the given path;
- the first position (7) being within the storage fixture (6);
- the second position (31) being adjacent the first position (7) and outside the storage fixture (6);
- continuing to unwind strip material (5b) from the second reel (2b) until the second reel (2b) is nearly empty;
- rotating the first reel (2a) about its axis (9) and unwinding strip material (5a) therefrom and feeding the said strip material (5a) along said given path while adjacent to, and at substantially the said same predetermined normal speed, as the strip material (5b) from the second reel (2b) travels along said given path;
- unloading the second reel (2b) from the said transfer element (26) and removing the second reel (2b) from the second position (31);
- moving the transfer element (26) to the first position (7);
- rotatably mounting the first reel (2a) on the transfer element (26) while the strip material (5a) is being unwound therefrom at a normal speed;
- and
- moving the transfer element containing the first reel (2a) from the first position to the second position while the strip material (5a) is being unwound from the first reel (2a) and fed to the said given path at said normal speed.
A method of feeding and changing reels (2) of strip material (5) on a manufacturing machine (4), comprising:
- positioning a plurality of reels (2), containing wound strip material, on a storage fixture (6);
- moving a first (2a) of said reels (2) to a first position (7) by a feeding means (8, 21);
- supporting the first reel (2a) in the first position by means of driving support means (16, 17) for rotating the first reel (2a) about its axis (9);
- mounting a second reel (2b), containing strip material (5b) to be unwound and supplied therefrom to a given path, on a transfer element (26) located at a second position (31);
- unwinding strip material (5b), at a predetermined normal speed, from the strip-supplying second reel (2b) located at the second position (31) occupied successively by second reels (2b) and feeding the unwound strip material (5b) along the given path;
- the first position (7) being within the storage fixture (6);
- the second position (31) being adjacent the first position (7) and outside the storage fixture (6);
- continuing to unwind strip material (5b) from the second reel (2b) until the second reel (2b) is nearly empty;
- activating the driving support means (16, 17) to rotate the first reel (2a) about its axis (9) so as to unwind strip material (5a) therefrom and feed the said strip material (5a) along said given path while adjacent to, and at substantially the said same predetermined normal speed, as the strip material (5b) from the second reel (2b) travels along said given path;
- unloading the second reel (2b) from the said transfer element (26) and removing the second reel (2b) from the second position (31);
- moving the transfer element (26) to the first position (7);
- rotatably mounting the first reel (2a) on the transfer element (26) while the strip material (5a) is being unwound therefrom at a normal speed;
- and
- moving the transfer element containing the first reel (2a) from the first position to the second position while the strip material (5a) is being unwound from the first reel (2a) and fed to the said given path at said normal speed.
