Abstract

An apparatus for conveying a roll such as a paper web roll set on the roll stand of a corrugator to a predetermined location at low speed, with a small initial force and without scratches or other damage to the roll. The apparatus includes a plurality of flat plate-shaped bases arranged end-to-end in the direction in which the roll is conveyed, a plurality of fulcrum shafts each passing through shaft holes in a corresponding base to allow each base to pivot on its shaft, raising and lowering units beneath each base to raise and lower the base, a load sensing unit below the downstream side of each base to detect a load exerted on the base, and a controller responsive to a signal from the load sensing unit to control raising and lowering units at a subsequent stage. When the bases are assembled together with the fulcrum shafts, a conveyance path for conveying the roll to the predetermined final location at low speed and without any acceleration is formed.

Dependent claims

An apparatus for conveying a roll-shaped article on a conveyance path comprising;

a plurality of flat plate-shaped bases arranged end-to-end in a direction in which said roll-shaped article is conveyed, each of said bases including:
a projection on a downstream side thereof and a recess on an upstream side thereof for receiving a corresponding projection on an adjacent one of said plurality of bases;
an upper smooth surface extending substantially parallel to a bottom surface of the base;
and at least one fulcrum shaft hole, said fulcrum shaft hole being formed through the base;
a plurality of fulcrum shafts, each transversely disposed through said at least one fulcrum shaft hole in a corresponding one of said plurality of bases, wherein each base is pivotably disposed to turn about a corresponding fulcrum shaft disposed through said at least one fulcrum shaft hole, said fulcrum shafts for linking said bases to form said conveyance path;
a plurality of raising and lowering means, each disposed below a corresponding base to raise and lower said base;
a plurality of load sensing means, each disposed below the downstream side of a corresponding base to sense a load on said base and to generate a load sensing signal indicative of said load;
and
a controller responsive to said load sensing signal to actuate raising and lowering means disposed below a base at a subsequent stage.
