Abstract

A method to form bundles (11) of one or more layers (20) of adjacent rolled sections (12). The method comprises discharging the rolled sections (12) from a terminal end (13a) of a transporter to cause the rolled sections (12) to fall from the terminal end (13a) onto discharge rods (14); forming at least one layer (20) of the rolled sections (12), which fall from the terminal end (13a) of the transporter (13) onto the discharge rods (14), the discharge rods (14) being arranged parallel to the transporter (13) and underneath the upper plane where the sections (12) are transported on the transporter (13). The discharge rods (14) are axially displaced with respect to the transporter (13) to define from time to time a lateral discharge space ("s") adjacent the terminal end (13a), for placing the sections (12) on the rods (14), wherein the lateral discharge space ("s") equals a transverse dimension of each rolled section (12). The axial displacements ("s") of the rods (14) with respect to the transporter (13) are correlated with the discharge of the sections (12) from the transporter (13). The discharge rods (14) progressively retract to transfer the layer (20) of the discharge rods (14) to a storage and unloading assembly (17) which has a least one transfer element (21) located on a plane below the discharge rods and lowering from time to time the transfer element (21) to discharge the rolled sections. Repeating these steps progressively forms a bundle (11) with a desired number of layers (20). A device for performing this process is also provided.

Dependent claims

A method to form bundles (11) of one or more layers (20) of rolled sections (12), each layer (20) including at least a row of adjacent rolled sections (12) comprising:

transporting each rolled section (12) on a transporter (13) having a terminal end (13a), wherein the rolled sections (12) lie adjacent to each other in a direction substantially at right angles to the longitudinal axis of the sections (12) on an upper plane during said transporting
discharging said rolled sections (12) from the terminal end (13a) of the transporter to cause the rolled sections (12) to fall from the terminal end (13a) onto discharge rods (14);
forming at least one layer (20) of said rolled sections (12), which fall from the terminal end (13a) of the transporter (13) onto said discharge rods (14), said discharge rods (14) being arranged parallel to the transporter (13) and on a plane underneath the upper plane where the sections (12) are transported on the transporter (13),
axially displacing the discharge rods (14) with respect to the transporter (13) to sequentially define from time to time, a series of lateral discharge spaces ("s") adjacent the terminal end (13a), for placing the sections (12) on the rods (14), wherein each lateral discharge space ("s") equals a transverse dimension of each rolled section (12),
correlating the axial displacing of the rods (14) with respect to the transporter (13) to be sequential with the discharge of the sections (12) from the transporter (13);
progressively retracting the discharge rods (14) to transfer the layer (20) from the discharge rods (14) to a storage and unloading assembly (17) which has at least one transfer element (21) located on a plane below the discharge rods (14);
lowering from time to time the transfer element (21) by a distance substantially correlated to the height of the layer (20) located on the rods (14);
progressively forming a bundle (11) with a desired number of layers (20) by the sequentially repeating said forming of said at least one layer (20) on the discharge rods (14) and the subsequent unloading of the at least one layer (20) onto the transfer element (21);
discharging the bundle (11) from the storage and unloading assembly (17).

6 more elements

A device to form bundles (11) of one or more layers (20) of rolled sections (12), each layer (20) comprising at least one row of adjacent rolled sections (12), the device being used in cooperation with a transporter (13) suitable to transport the rolled sections (12) as they lie one rolled section (12) adjacent to another rolled section (12) in a direction substantially at right angles to the longitudinal axis of the rolled sections (12) themselves, the transporter having a terminal end (13a) for discharging the sections (12) to cause the sections (12) to fall from the transporter (13), the device being suitable for discharging said sections (12) to at least a station (23) to perform at least one function selected from the group consisting of storing, tying or discharging the bundles (11), the device comprising:

discharge rods (14) on which the layer (20) is formed, the discharge rods (14) being locatable to receive sections (12) as the sections (12) fall from the terminal end (13a) of the transporter (13) and be in a position underneath an upper plane of the transporter (13),
the discharge rods (14) being axially movable with respect to the transporter (13) on a plane substantially parallel to the upper plane of the transporter (13) from a first position where the formation of the layer (20) is begun to sequentially define from time to time, a series of lateral discharge spaces ("s") adjacent the terminal end (13a), for placing the sections (12) on the rods (14), wherein each lateral discharge space ("s") equals a transverse dimension of each rolled section (12), to a second position where the formation of the layer (20) is completed on the discharge rods (14),
a storage and unloading assembly (17) upon which the laver (20) of rolled sections (12) is deposited to form at least a part of the bundle (11) comprising at least a transfer element (21), the transfer element (21) being arranged in a position underneath the discharge rods (14) and being movable from a first position to receive the layer (20) from the discharge rods (14) to at least a second position which is achieved when the deposited rolled sections (12) are transferrable to the station (23) to perform at least one function selected from the group consisting of storing, tying, or discharging the bundles.
