Abstract:
A method and apparatus is disclosed for receiving a helical formation of rings (12) free falling from the delivery end of a conveyor and for gathering the rings into an upstanding cylindrical coil. The free falling rings encircle a vertically disposed guide (16) and are supported initially on elevated intercepting elements (20). The interceptor elements are gradually lowered past a coil plate (18) onto which the accumulated rings are transferred. The coil plate is then covered to accommodate continued formation of the coil, and the intercepting elements are returned to their elevated position. (Figures 4A∼4F).
Abstract:
In a rolling mill, a reforming chamber (24) is positioned to receive rings (20) of hot rolled steel rod descending along a vertical path from the delivery end of a conveyor (22) onto a support (40) on an underlying carrier (36). The carrier has an upstanding stem (42) around which the rings (20) accumulate to form a cylindrical coil C. First, interceptor elements (30) operate above the carrier (36) to interrupt the descent of rings (20), and second interceptor elements (60,62) supported on the carrier (36) beneath the first interceptor elements (30) operate to subdivide the coil C being formed around the stem (42) into upper and lower segments, with a gap therebetween occupied by the second intercepting elements (60,62).
Abstract:
In an apparatus for receiving a series of loops (L) descending along a vertical path from the delivery end of a conveyor (12) and for accumulating the thus received loops (L) into an annular coil, a device for horizontally distributing the descending loops (L). The device includes a ring (18) surrounding the vertical path. The ring (18) has a cylindrical vertical wall (18a) and a radially outwardly extending horizontal ledge (18b). A curved guide member (32) extends around a segment of the ring (18) and has leading and trailing ends (32a,32b). The guide member (32) protrudes inwardly from the ring (18) into the vertical path, with the extent of the inward protrusion being greater at the trailing end (32b) than at the leading end (32a). The guide member (32) is in mechanical interengagement with the horizontal ledge (18b) and in horizontal abutting engagement with the vertical wall (18a) to thereby accommodate vertical placement and removal of the guide member (32) onto and off of the ring (18) without attendant radial displacement of the guide member (32) with respect to the ring (18).
Abstract:
An apparatus for gathering descending annular rings, e.g. of steel rod, into an upstanding annular coil is disclosed. An auxiliary coil plate (24) is mounted on and vertically adjustable with respect to the conventional elevator platform (16). The coil plate is designed to be raised into the coil forming chamber (14) well above the level of the shear mechanism (42). By doing so, the ring free fall distance is beneficially reduced at an early stage in the coil formation cycle when the bottom most rings are displayed.
Abstract:
A rolling mill reforming station (24) has an annular chamber (26) into which rings (L) are dropped to accumulate in coil form. A guide member (54) is rotated about a circular path (P a ) surrounding the path of ring descent. The guide member has a three-dimensionally curved guide surface (60) configured in the general shape of a plough share which distributes the descending rings around the circumference of the accumulating coil.
