Abstract

An apparatus is disclosed for controlling the movement of flat bottomed articles in a plurality of different directions relative to a supporting platform. The article is supported on a plurality of clusters of helical, freely rotatable rollers mounted on a plurality of shafts. Selected ones of the shafts, or groups of shafts, each lying in one of a plurality of zones, are selectively driven in a clockwise direction, a counterclockwise direction or are held stationary. Selective control of the shafts enable the apparatus to move the article parallel to the longitudinal axis of the platform in two selected directions, perpendicular to the longitudinal axis in two selected directions; diagonally of the longitudinal axis in four selected directions, and either clock or counterclockwise about an axis normal to the flat bottom of the article.

Dependent claims

An apparatus for selectively moving an article having a flat bottom lying in a support plane in a plurality of different directions, comprising:

means defining a platform having a longitudinal axis and a transverse axis;
means defining a plurality of parallel shafts journaled on said platform and having axis of rotation parallel to said transverse axis of the platform;
a plurality of independently controlled selectively operated power means each operatively connected to at least one of said shaft means;
a plurality of roller mounting means secured to each shaft;
a plurality of evenly space barrel shaped rollers journaled on each roller mounting means and having their axes of rotation disposed helically at an acute angle relative to the axis of rotation of their associated said shaft, said acute angle of said helical rollers mounted on said shaft being reversed relative to the acute angle of the rollers mounted on said at least one other shaft, and
control means for independently and selectively controlling each of said plurality of power means for maintaining said associated at least one shaft stationary or for driving said operatively connected at least one shaft in a selected direction.

means defining a roller platform having a longitudinal axis and a transverse axis;
means defining a first plurality of shafts in a first zone journaled on said platform and having longitudinal axes parallel to said transverse axis of said platform;
first power means operatively connected to said first shafts;
means defining a second plurality of shafts in a second zone journaled on said platform and having longitudinal axes parallel to said transverse axis of said platform;
second power means operatively connected to said second shafts;
means defining a third plurality of shafts in a third zone journaled on said platform having longitudinal axes parallel to said transverse axis of said platform;
third power means operatively connected to said third shafts;
means defining a fourth plurality of shafts in a fourth zone journaled on said platform and having longitudinal axes parallel to said transverse axis of said platform;
fourth power means operatively connected to said fourth shafts,
a plurality of roller mounting means on each of said shafts;
a plurality of evenly spaced barrel shaped rollers journaled on each roller mounting means and having their axes of rotation disposed helically at an acute angle relative to the axes of their associated shaft, said acute angle of said helical rollers mounted on the shafts in said first and third zones being reversed from the acute angle of the helical rollers mounted on the correpsonding shafts in said second and fourth zones;
and
control means for independently and selectively controlling said first, second, third and fourth power means between a locked position holding their associated plurality of shafts stationary and positions which selectively rotate all shafts in the associated zones in clockwise or counterclockwise directions thereby moving the article in predetermined directions relative to said platform.
