Stacking machine for rolled bar shapes

A stacking machine for the interlocking method of stacking rolled bar shapes on a stacking roller table on which a completed stack is discharged toward the next area, utilizing rotatable magnetic turnover arms for inversion of a partial group of n-1 bars onto a non-inverted partial group of n bars, characterized by

• (a) a feed roller table (11a), the width of which is larger than that of the two partial groups of 2n-1 bars,
• (b) a wedge-shaped separating gib (29) extending over the length of the feed roller table portion ahead of the stacking machine (27), for separation of a group of 2n-1 bars into two partial groups of bars (50, 51), continued down to the end of the feed roller table by two separating walls (29a) spaced in parallel relationship,
• (c) vertical guides (30) disposed between the separating walls (29a) over the length of the feed roller table, to guide up and down movement of two groups of push rods (31, 32) in which either said push rods may operate in said groups or said groups may operate commonly,
• (d) swivel shafts (37, 40) supported on the upper ends of the push rods of each group, with swivel drives for rotatable braking skids (38, 41) connected to the swivel shafts for elevation of the partial groups of bars from the roller table in the horizontal position of the braking skids which extend in groups left and right over the partial widths of the feed roller table and which may rotate into the vertical position subsequent to an upward stroke, in which they may move downward in simultaneous alignment with the vertical guides (30) of the push rods, to a point from which they may rotate back into the horizontal working position without intersecting the roller table level,
• (e) the design of the braking skids which, in their horizontal working positions, extend over the partial width (B) of the feed roller table for the partial groups (51) of n-1 bars, to function as turnover magnets (41) which may be rotated selectively through 90.degree. or 180.degree.,
• (f) horizontal guides (42) approximately on level with the turnover magnet braking skids (41) in their uppermost horizontal swivel positions, provided to guide back and forth movement of receiving magnets (43) which move double layers of bars (52) suspended therefrom from their position on the roller table partial width (A) for partial groups (50) of n bars to a position over the stacking roller table (28) located beside the feed roller table,
• (g) vertical guides (60) disposed externally beside the stacking roller table for up and down movement of push rods (45) which support vertical swivel shafts (46) and swivel drives (48), the swivel shafts being connected to stacking table arms (49) which may move back and forth horizontally to receive double layers of bars (52) and which may swivel back into their receiving positions above the stack of bars exiting on the stacking roller table and below the level of the horizontally supported receiving magnets (43) without intersecting the stack.
