Abstract
A vibrating conveying system having a plurality of rotating shafts and associated eccentric weights uses a sliding eccentric weight or weights mounted on one or more driving shafts to reverse the movement of the articles carried by the conveyor. The sliding weights move between first and second spaced positions relative to the driving shaft when the rotation of the driving shaft is reversed and are latched into place once in the selected positions preventing further movement while the apparatus is operating.
Claims13
A vibrating conveyor apparatus for reversing the movement of articles carried by said apparatus comprising
- a conveying trough for moving articles through vibratory motion imparted to said trough;
- a stationary frame;
- a plurality of spring members mounting said trough on said frame;
- a vibrating assembly for imparting vibratory motion to said trough, said assembly comprising a plurality of shaft components mounting eccentric weights adapted to be rotated to generate said vibratory motion, one of said shaft components mounting a first eccentric weight that is movable with respect to said one shaft component between a first predetermined latched position and a second predetermined latched position, said first eccentric weight and said shaft component having a latching mechanism that latches said first eccentric weight in said first predetermined latched position when said shaft component is rotated in a first direction and in said second predetermined latched position when said shaft component is rotated in a direction reverse to said first direction.

A vibrating conveyor apparatus for reversing the movement of articles carried by said apparatus comprising
- a conveying trough for moving articles through vibratory motion imparted to said trough;
- a stationary frame;
- a plurality of spring members mounting said trough on said frame;
- a vibrating assembly for imparting said vibratory motion to said trough, said assembly including a plurality of shafts and associated eccentric weights for generating said vibratory motion and a hub assembly fixed to one of said shafts,
- said hub assembly mounting a first eccentric weight that is movable with respect to said hub assembly and said one shaft between a first position and a second position, said first eccentric weight having a first stop element and said hub assembly having a pair of spaced stop components,
- said stop element abutting one of said stop components when said first eccentric weight is in said first position and abutting an other of said stop components when said eccentric weight is in said second position,
- said first eccentric weight and said hub assembly collectively defining a latching mechanism that is
- activated when said stop element abuts said stop components and holds said first eccentric weight in respective said first and second positions and
- deactivated when a direction of rotation of said one shaft is reversed thereby allowing said first eccentric weight to move relative to said one shaft between said first and second positions.

A vibratory conveying apparatus comprising a conveying trough for moving articles through vibratory motion imparted to said trough;
- a stationary frame;
- a plurality of spring members mounting said trough on said frame;
- a vibrating assembly for imparting said vibratory motion to said trough, said assembly including a central shaft and a pair of shafts parallel to and located on either side of said central shaft, said shafts operably connected to one another so that said central shaft rotates in the opposite direction to said pair of shafts, each of said pair of shafts mounting eccentric weights and said central shaft having at least one hub assembly fixed thereto,
- said hub assembly mounting a first eccentric weight that is movable with respect to said hub assembly and said central shaft between a first position and a second position, said first eccentric weight having a first stop element and said hub assembly having a pair of spaced stop components,
- said stop elements abutting one of said stop components when said first eccentric weight is in said first position and abutting an other of said stop components when said eccentric weight is in said second position,
- said first eccentric weight and said hub assembly collectively defining a latching mechanism that is
- activated when said stop element abuts said stop components and holds said first eccentric weight in respective first and second positions and
- deactivated when a direction of rotation of said central shaft is reversed and thereby allowing said first eccentric weight to move relative to said central shaft between said first and second positions.
