A stacker for the stacking of metallic section bars in alternating upright and reverse layers in an orderly manner, in particular of section bars originating from rolling mills by a conveying line which includes a plurality of trolleys equipped with lances capable of moving forward and backward from the reception area of a stack of section bars to a deposition area of the same layer of section bars in an upright position, and a plurality of magnetic heads capable of being actuated to rotate by a first set of actuating members from a picking-up position of another layer of section bars to a depositing position of the same layer of section bars reversed on top of the first layer of upright section bars. According to the invention, each head performs both a vertical shifting motion essentially parallel to itself and an oscillating motion, where the shifting motion is actuated by a second set of actuating mechanisms independent of the first and the said oscillating motion is actuated by a third set of actuating mechanisms also independent of the first set.

Stacker for the stacking of metallic section bars in alternating,

An automatic stacker with rotary heads for stacking in an ordered manner in alternate upright and inverted layers rolled metal sections originating from a rolling mill via a transport line is characterised in that each head also undergoes vertical translational movement in the directions of the arrow substantially parallel to itself, such movement being provided by a second drive mechanism independent of a first providing rotation of the head itself. In this manner, the head deposits softly and with precision each layer of sections on the layer placed below, thus avoiding jamming and improper stacking.

Automatic stacker with rotary heads for stacking, in an ordered manner

A rotary electromagnetic head for automatic stackers of iron sections originating from a rolling mill. And an expulsion device is provided with a bar rotating together with the head but also provided with simultaneous movement relative to the head. This relative movement is caused by a cam against the action of a counteracting spring.

Rotary electromagnetic head with improved mechanical expulsion device

A facility for in-line heat treatment of hot-rolled products, for example, long rods (16) includes: a tank (11) suitable for containing a refrigerating liquid medium (12), a plate (13) with stationary rakes (14) and mobile rakes (15) suitable for receiving the products (16) and transporting them through the tank (11) and outside of it on heat treatment performed, and closure lids (27) arranged above the plate (13).
