BELT CONVEYOR
A conveyor is disclosed herein. An embodiment of the conveyor comprises an upper side, an under side, a first end, a second end, and a frame comprising a first side and a second side. At least one roller is located in the underside, the at least one roller extends between the frame first side and the frame second side. A belt extends between the first end and the second end, wherein the belt contacts the at least one roller. A bracket connects the first side of the frame to the at least one roller. The bracket comprises a first portion that is pivotally connected to the first side of the frame and a second portion pivotally connected to the roller, the bracket enables the roller to pivot relative to the first side of the frame.
1 . A conveyor comprising:
an upper side;
an under side;
a first end;
a second end;
a frame comprising a first side and a second side;
at least one roller located in said underside, said at least one roller extending between said frame first side and said frame second side;
a belt extending between said first end and said second end, wherein said belt contacts said at least one roller;
a first bracket connecting said first side of said frame to said at least one roller;
said first bracket comprising a first portion that is pivotally connected to said first side of said frame and a second portion pivotally connected to said roller, said first bracket enabling said roller to pivot relative to said first side of said frame.
2 . The conveyor of claim 1 , wherein said roller has a first end located proximate said first side of said frame and a second end located proximate said second side of said frame, wherein said first bracket enables said first end of said roller to move closer to said upper side than said second end of said roller.
3 . The conveyor of claim 1 and further comprising a second bracket, said second bracket comprising a first portion that is pivotally connected to said second side of said frame and a second portion pivotally connected to said roller, said second bracket enabling said roller to pivot relative to said second side of said frame.
4 . The conveyor of claim 3 , wherein said roller has a first end located proximate said first side of said frame and a second end located proximate said second side of said frame, wherein said second bracket enables said second end of said roller to move closer to said upper side than said first end of said roller.
5 . The conveyor of claim 1 , wherein said first bracket enables said roller to move in a direction normal to said first side of said frame.
6 . The conveyor of claim 1 , wherein said first bracket has a motor connected thereto, said motor enabling said first bracket to pivot relative to said first frame.
7 . A conveyor comprising:
an upper side;
an under side;
a first end;
a second end;
a frame comprising a first side and a second side;
a roller located in said underside, said roller extending between said frame first side and said frame second side, said roller having a first end located proximate said first side of said frame and a second end located proximate said second side of said frame;
a belt extending between said first end and said second end, wherein said belt contacts said at least one roller;
a first bracket connecting said first side of said frame to said first side of said roller, said first bracket comprising a first portion that is pivotally connected to said first side of said frame and a second portion pivotally connected to said first end of said roller, said first bracket enabling said roller to pivot relative to said first side of said frame; and
a second bracket connecting said second side of said frame to said second side of said roller, said second bracket comprising a first portion that is pivotally connected to said second side of said frame and a second portion pivotally connected to said second end of said roller, said second bracket enabling said roller to pivot relative to said second side of said frame.
8 . The conveyor of claim 7 , wherein said first bracket and said second bracket enable said roller to move in a direction normal to said first side of said frame.
9 . The conveyor of claim 7 , wherein said first bracket and said second bracket enable said first end of said roller to move closer to said upper side than said second side of said roller.
10 . The conveyor of claim 7 , wherein said first bracket has a motor connected thereto, said motor enabling said first bracket to pivot relative to said first frame.
11 . A method for aligning a belt used in a conveyor, said conveyor having an upper side and an under side, wherein items are transported by a continuous belt on said upperside and wherein a roller on said underside supports said belt during the return, said method comprising:
supporting said belt using said roller; and
lifting a side of said roller when said belt wanders, said lifting causing said belt to wander perpendicular to the movement of said belt.
12 . The method of claim 11 , wherein said roller has a first end and a second end, said belt being located between said first end and said second end; and wherein said lifting comprises lifting said first end closer to said upperside than said second end.
13 . The method of claim 11 , wherein said conveyor comprises a bracket pivotally attaching said roller to a frame associated with said conveyor; and wherein said lifting comprises pivoting an end of said roller by way of said bracket.
14 . The method of clam 11 and further comprising sensing wandering of said belt; and wherein said lifting comprises lifting in response to said sensing.
