Abstract
A slat for a conveyor that has one or more curves.
Claims19
A conveyor utilizing a plurality of slats;
- said conveyor comprising:
- a) a helical support comprising:
- i) a first track, wherein at least a portion of said first track extends simultaneously with said helical support;
- ii) a second track separate from said first track, wherein at least a portion of said second track extends simultaneously with said helical support;
- and
- iii) a wall positioned between said first track and said second track;
- wherein at least a portion of said wall spirals simultaneously with said helical support;
- b) said plurality of slats traveling an endless pathway about said helical support;
- each slat having a superior article carrying side and an opposed side;
- wherein said opposed side further comprises:
- i) a first landing gear integral with said slat carrying a first wheel for engaging said first track, wherein vertical and horizontal movement but not rotational movement of said first wheel is limited by contact with said first track;
- and
- ii) a second landing gear integral with said slat carrying a second wheel for engaging said second track, wherein vertical and horizontal movement but not rotational movement of said second wheel is limited by contact with said second track;
- and
- c) a drive driving said plurality of slats.
12 more elements
An endless plurality of slats driven about a support, wherein said support comprises a first track proximate a first side of said support and a second track separate from said first track, proximate a second side of said support, wherein each of said plurality of slats comprises an article carrying side and an opposed side, and wherein one or more of said opposed sides comprises:
- a) a first landing gear carrying a first wheel for engaging said first track for limiting vertical and horizontal movement but not rotational movement of said first wheel such that said first wheel rotates in a first plane generally perpendicular to said slat;
- and
- b) a second landing gear carrying a second wheel for engaging said second track for limiting vertical and horizontal movement but not rotational movement of said second wheel such that said second wheel rotates in a second plane generally perpendicular to said slat.
A conveyor comprising:
- a) a plurality of slats comprising article carrying sides, opposed sides and a central transverse axis for each said slat, wherein one or more of said opposed sides comprises:
- i) a first landing gear, carrying a first wheel, located on a first side of said central transverse axis;
- and
- ii) a second landing gear, carrying a second wheel, located on a second side of said central transverse axis;
- and
- b) a support for said slats;
- said support comprising two tracks separate from each other and positioned on opposite sides of a wall of said conveyor;
- said tracks engaging at least some of said wheels, wherein at least one of said tracks comprises an upper rail and a lower rail.
5 more elements
A slat for an endless carrier of a conveyor;
- said slat comprising a superior article carrying side and an opposed side, wherein said opposed side further comprises first and second landing gears carrying wheels traversing an approximate distance of an article transportation path of said conveyor;
- said conveyor further comprising tracks, distinct from each other, limiting vertical and horizontal movement of said wheels, wherein axes of rotation of said wheels are parallel said article transportation path.
A slat for an endless loop traversing a conveyor;
- said slat comprising:
- a) a first side adapted for carrying articles;
- b) a central transverse axis;
- and
- c) a second side opposite said first side;
- said second side comprising landing gears on opposed sides of said central transverse axis, wherein each landing gear further comprises a wheel, set apart from said second side, including an axis of rotation parallel said slat;
- each said wheel adapted to engage a surface distinct from that of its opposed wheel, wherein at least one of said distinct surfaces limits vertical and horizontal movement of said wheels contacting said one distinct surface.
