An apparatus is disclosed for downending a vertically disposed cylindrical coil supported on an underlying pallet, with a stem projecting from the pallet through the coil. The apparatus comprises a cradle rotatable about a horizontal axis. A table on the cradle is configured and arranged to receive and retain the pallet with the coil in a vertical first position at which the coil extends across the horizontal axis. An electrically powered drive serves to rotate the cradle about the horizontal axis to translate the coil from its vertical first position to a horizontal second position.
1. Apparatus for downending a vertically disposed cylindrical coil supported on an underlying pallet, with a stem projecting from the pallet through the coil, said apparatus comprising:
a cradle rotatable about a horizontal axis, said cradle having at least one partially circular track arranged concentrically with respect to said horizontal axis, said track being supported on stationary bearings for rotation about said horizontal axis;
a table on said cradle, said table being configured and arranged to receive and retain said pallet with said coil in a vertical first position above said horizontal axis and at which the coil axis extends across said horizontal axis; and
drive means for rotating said cradle about said horizontal axis to translate said coil from said vertical first position to a horizontal second position;
wherein said drive means comprises a chain of finite length extending around said track, with opposite ends of said chain fixed with respect to said track, and with a segment of said chain between the chain ends being engaged by a sprocket, whereby rotation of said sprocket will result in rotation of said track and said cradle about said horizontal axis.
2. The apparatus of claim 1 wherein said sprocket is electrically driven.
3. The apparatus of claim 1 wherein two of said circular tracks are arranged in parallel planes, with said table being located between said tracks.
4. The apparatus of claim 1 wherein said table is a roller table on which said pallet is received along said horizontal axis.
5. The apparatus of claim 4 further comprising means for retaining said pallet on said roller table during translation of said coil from said vertical first position to said horizontal second position.
6. The apparatus of claim 3 wherein said table is a roller table on which said pallet is received along said horizontal axis.
7. The apparatus of claim 6 further comprising means for retaining said pallet on said roller table during translation of said coil from said vertical first position to said horizontal second position.
8. Apparatus for downending a vertically disposed cylindrical coil supported on an underlying pallet, with a stem projecting from the pallet through the coil, said apparatus comprising:
a cradle rotatable about a horizontal axis, said cradle having a pair of partially circular tracks arranged concentrically with respect to and spaced one from the other along said horizontal axis;
a table positioned on said cradle between said tracks, said cradle being configured and arranged to receive and retain said pallet with said coil in a vertical first position above said horizontal axis and at which the coil axis extends across said horizontal axis; and
drive means for rotating said cradle about said horizontal axis to translate said coil from said first position to a horizontal second position, said drive means comprising chains of finite length extending around said tracks, with opposite ends of said chains fixed with respect to their respective tracks, and with segments of said chains between said ends being engaged by sprockets, whereby rotation of said sprockets will result in rotation of said tracks and said cradle about said horizontal axis.
9. The apparatus of claim 8 wherein said sprockets are carried on a common shaft driven by an electrically powered motor.
