Abstract

A conversion system wherein a crankshaft drives the motion of the tooling assemblies within a number of lanes is provided. The crankshaft is structured to move the tooling assemblies associated with less than the total number of lanes. That is, for example, a four lane conversion press could include two crankshafts each actuating the tooling assemblies of two lanes. In an exemplary embodiment, each lane has a single associated crankshaft. The conversion system includes a multiple press drive assembly with a clutch/brake assembly and a flywheel assembly. The clutch/brake assembly is structured to suspend operation of the press units while the flywheel assembly stores energy in a flywheel. When operation of the press units is restarted, energy from the flywheel aids the motor in bringing the press units to an operating speed.

First claim

What is claimed is:

1. A multi-press drive assembly for a conversion system, said conversion system including a number of crankshafts, said drive assembly comprising:
a motor including an output shaft;
a clutch/brake assembly including an output shaft;
a drive linkage assembly including a number of gearboxes, a number of linkage shafts, and a number of press shafts;
said clutch/brake assembly operatively coupled to said motor output shaft;
said clutch/brake assembly output shaft operatively coupled to at least one said drive linkage assembly linkage shaft;
each said press shaft structured to be operatively coupled to a crankshaft;
said clutch/brake assembly includes a flywheel assembly and a forward hub assembly;
said forward hub assembly including a wheel assembly and a clutch assembly;
said forward hub assembly wheel assembly fixed to said clutch/brake assembly output shaft;
said forward hub assembly clutch assembly including a mounting and a movable clutch pad;
said forward hub assembly clutch assembly mounting coupled to said forward hub assembly wheel assembly;
said forward hub assembly clutch assembly clutch pad movably coupled to said forward hub assembly clutch assembly mounting; and
said forward hub assembly clutch assembly clutch pad moves between a first position, wherein said forward hub assembly clutch assembly clutch pad is not fixed to said clutch/brake assembly flywheel assembly, and a second position, wherein said forward hub assembly clutch assembly clutch pad is fixed to said clutch/brake assembly flywheel assembly.

2. The multi-press drive assembly of claim 1 , wherein:
said clutch/brake assembly flywheel assembly includes a flywheel body, wherein said clutch/brake assembly flywheel body is generally a torus including a central passage; and
said clutch/brake assembly flywheel body is rotatably disposed about said clutch/brake assembly output shaft.

3. The multi-press drive assembly of claim 2 , wherein:
said clutch/brake assembly flywheel assembly includes a clutch disk, said clutch/brake assembly flywheel assembly clutch disk fixed to said clutch/brake assembly flywheel body; and
said hub assembly forward clutch assembly clutch pad moves between a first position, wherein said forward hub assembly clutch assembly clutch pad is not fixed to said clutch/brake assembly flywheel assembly clutch disk, and a second position, wherein said forward hub assembly clutch assembly clutch pad is fixed to said clutch/brake assembly flywheel assembly clutch disk.

4. The multi-press drive assembly of claim 3 , wherein:
said forward hub assembly clutch assembly includes a piston;
said forward hub assembly clutch assembly piston including a body;
wherein said forward hub assembly clutch assembly piston body is generally toroidal and includes a number of axial mounting pockets;
said forward hub assembly wheel assembly includes a wheel body;
wherein said forward hub assembly wheel body is generally toroidal and defines a clutch assembly cavity;
said forward hub assembly clutch assembly clutch pad includes a generally toroidal body;
said forward hub assembly clutch assembly clutch pad body fixed to said forward hub assembly clutch assembly piston body;
said forward hub assembly clutch assembly piston body and said forward hub assembly clutch assembly clutch pad body movably disposed in said forward hub assembly wheel body clutch assembly cavity; and
said forward hub assembly clutch assembly piston body moves between a first position, wherein said forward hub assembly clutch assembly clutch pad is not fixed to said clutch/brake assembly flywheel assembly clutch disk, and a second position, wherein said forward hub assembly clutch assembly clutch pad is fixed to said clutch/brake assembly flywheel assembly clutch disk.

5. The multi-press drive assembly of claim 4 , wherein:
said clutch/brake assembly includes a pneumatic actuator assembly; and
said clutch/brake assembly pneumatic actuator assembly structured to move said forward hub assembly clutch assembly piston body between said first position and said second position.
