Abstract
Pick-up device (10) configured to selectively pick up and extract at least one bar (B) from a plurality of bars (B) disposed on a feed plane (111) and to position it on a delivery plane (12), said pick-up device (10) comprising a support arm (11) terminally provided with a pick-up head (12). The present invention also concerns an apparatus (100) for feeding bars (B) comprising the device (10) as above and a corresponding method for picking up bars (B).
Claims9
A pick-up device (10), comprising:
- a support arm (11) terminally provided with a pick-up head (12), configured to selectively pick up and extract, from a feed plane (111), at least one bar (B) in order to position the bar on a delivery plane (112), wherein said pick-up device (10) comprises:
- a temporary support means (13) comprising:
- at least one central support (14) provided with seatings (30) configured to support a central portion (b1) of said at least one bar (B);
- lateral supports (16) movable away from said central support (14) in a transverse direction (T), said lateral supports (16) configured to support and extract lateral portions (b2, b3) of said at least one bar (B) to align said lateral portions to said central portion (b1);
- and
- vertically movable secondary supports (17) disposed at a lower height than that of said central support (14) and said lateral supports (16).

A pick-up device (10), comprising:
- a support arm (11) terminally provided with a pick-up head (12), configured to selectively pick up and extract, from a feed plane (111), at least one bar (B) in order to position the bar on a delivery plane (112), wherein said pick-up device (10) comprises:
- a temporary support means (13) comprising:
- at least one central support (14) provided with seatings (30) configured to support a central portion (b1) of said at least one bar (B), and
- lateral supports (16) movable away from said central support (14) in a transverse direction (T), said lateral supports (16) configured to support and extract lateral portions (b2, b3) of said at least one bar (B) to align said lateral portions to said central portion (b1),
- wherein said support arm (11) is configured to move said pick-up head (12) in a first linear positioning direction (D) toward the said temporary support means (13) and a second linear positioning direction (D) away from said temporary support means (13),
- wherein said pick-up head (12) comprises a gripping matrix (23) movable in an operating direction (F) transverse to said first and second linear positioning direction (D) and transverse to said transverse direction (T), and
- wherein said gripping matrix (23) is made, or coated, in whole or in part, with a magnetic material or an electromagnetic material, and has a gripping surface (26) provided with a plurality of gripping seatings (27), wherein said plurality of gripping seatings have a downward concavity and wherein each of said plurality of gripping seatings is separated by a predetermined pitch (P).
4 more elements
A method for picking up bars (B), the method comprising:
- selectively picking up and extracting at least one of said bars (B) disposed on a feed plane (111) of an apparatus (100) for feeding said bars (B), and
- positioning said at least one bar (B) downstream on a delivery plane (112) of said apparatus (100) with a pick-up device (10) by moving a support arm (11) terminally provided with a pick-up head (12),
- wherein said method provides temporarily supporting said at least one bar (B) on a temporary support means (13) comprising at least one central support (14) provided with seatings (30) to support a central portion (b1) of said at least one bar (B), lateral supports (16) movable away from said central support (14) in a transverse direction (T) to support and extract respective lateral portions (b2, b3) of said at least one bar (B) to align said lateral portions to said central portion (b1), and vertically movable secondary supports (17) disposed at a lower height than that of said central support (14) and said lateral supports (16).
