Method and installation for the deposition of profiled rods

A method for an oriented deposition of hexagonal profiled rods (2), in which the cross-section of the individual profiled rods (2) of a first row of profiled rods (3) are arranged side by side are deposited with their longitudinal edges (5) pointing downward in the direction of a stacking table (9) of a stacking installation (1), whereby the method includes following steps:

• providing at least an initial number of n-profiled rods (2) on a feed table (8) of the stacking installation (1), and placing the profiled rods (2) side by side as well as resting on one of their side areas (6) on the feed table (8),
• forming a stacking shaft (11) at the stacking table (9) of the stacking installation (1) subsequently at the feed table (8), whereby the stacking shaft (11) is formed with a width (14) between first and second stacking shaft walls (12, 13), the width (14) which is formed at least in a product value of a cross-section dimension between the side areas (6) of the profiled rods (2) aligned as running parallel to one another and the initial number “n” of the profiled rods (2),
• adjusting several first transfer arms (17) starting from the feed table (8) so that first ends (20) of the first transfer arms (17) protrude above the stacking shaft (11) on the side facing away from the feed table (8),
• transferring the initial number of n-profiled rods (2) in vertical direction with respect to their longitudinal extensions by means of a transfer device (10) on the first transfer arms (17) present above the stacking table (9),
• placing the initial number of n-profiled rods (2) on support areas (18) arranged horizontally on the transfer arms (17) so that the first profiled rod (2) with its longitudinal edge (5) in the direction of transfer is brought up against at least at the first stacking shaft wall (12) arranged at a distance from the feed table (8),
• adjacently holding the initial number of n-profiled rods (2) at their respective longitudinal edges (5) facing each other by means of the transfer device (10),
• re-adjusting the first transfer arms (17) in direction to the feed table (8), whereby the first end areas of the first transfer arms (17) each adjoining the horizontally aligned support areas (18) point towards the first end (20) of sloping aligned guide surface (21), and during the re-adjusting movement of the first transfer arms (17) the first profiled rod (2) is brought from its position at the horizontally aligned support surfaces (18) in the area of the sloping aligned guide surfaces (21),
• in doing so, swiveling the first profiled rod (2) along its longitudinal axis so that it lies with one of its side surfaces (6) at the first stacking shaft wall (12) and with one of its other side surfaces (6) at the sloping aligned guide surfaces (21) of the first transfer arms (17),
• guided lowering, of the first profiled rod (2) with one of its side surfaces (6) at the first stacking shaft wall (12) as well as with one of its other side surfaces (6) at the guide surfaces (21) until it is deposited directly with its longitudinal edge (5) at a stacking shaft bottom (15) of the stacking shaft (11),
• consecutively rotating the further profiled rods (2) on their longitudinal axis for building the first profiled rod row (3) so that the further profiled rods (2) are placed respectively with their side surfaces (6) at the sloping aligned guide surfaces (21) of the first transfer arms (17),
• guided lowering of the further profiled rods (2) until their direct contact with their respective longitudinal edges (5) at the stacking shaft bottom (15) of the stacking shaft (11) and, in doing so, completing the formation of the first profiled rod row (3), whereby both the outermost profiled rods (2) of the first profiled rod row (3) are supported respectively with their side surfaces (6) resting at both the stacking shaft walls (12, 13) of the stacking shaft (11) and form the profiled rod row (3) adjoining each other at their side surfaces (6).
