Side-flexing conveyor module with detachable roller assembly
View Patent ↗A link module suitable for use in a conveyor chain intended for travel along an intended direction on a given path. The module includes a first eye and a second eye adjacent the first eye. The eyes define a space therebetween. A roller assembly extends into the space and is detachably mounted between the first and second eyes.
1. A conveyor chain intended for travel along an intended direction on a given path, said conveyor chain comprising:
a chain pin;
a first link module including a first plurality of laterally spaced eyes extending in a direction of conveyor travel and which respectively have therein aligned first bores receiving said chain pin, and which define a series of spaces, said first link module further including a second plurality of laterally spaced eyes extending in a direction opposite to the direction of conveyor travel and being laterally offset from said first plurality of laterally spaced eyes;
a second link module including a third plurality of laterally spaced eyes which respectively have therein aligned second bores receiving said chain pin to prevent disconnection of said first and second modules; and
a roller assembly detachably mounted to at least one of said first and second link modules between adjacent laterally spaced eyes of said at least one of said first and second link modules, and a portion of said roller assembly extending downwardly from said at least one of said first and second link modules.
2. The conveyor chain as in claim 1 , in which said roller assembly engages said at least one of said first and second link modules in said space to detachably mount said roller assembly to said at least one of said first and second link modules.
3. The conveyor chain as in claim 1 , in which said detachable roller assembly includes a roller rotatably mounted on a spindle detachably mounted to said at least one of said first and second link modules.
4. A conveyor chain intended for travel along an intended direction on a given path, said conveyor chain comprising:
a chain pin;
a first link module including a first plurality of laterally spaced eyes which respectively have therein aligned first bores receiving said chain pin, and which define a series of spaces;
a second link module including a second plurality of laterally spaced eyes which respectively have therein aligned second bores receiving said chain pin to prevent disconnection of said first and second modules; and
a roller assembly detachably mounted to at least one of said first and second link modules between adjacent laterally spaced eyes of said at least one of said first and second link modules, and a portion of said roller assembly extending downwardly from said at least one of said first and second link modules, wherein said detachable roller assembly includes a roller rotatably mounted on a spindle detachably mounted to said at least one of said first and second link modules, and said spindle includes a stepped shaft having a first diameter and a smaller second diameter interposed between the first diameter and distal end of the shaft, said roller is rotatably mounted on the second diameter and abuts a step defining a boundary between said first and second diameters.
5. The conveyor chain as in claim 4 , in which a circumferential groove is formed in said second diameter proximal said shaft distal end for receiving a C-clip that axially locks said roller onto said shaft.
6. The conveyor chain as in claim 1 , in which said detachable roller assembly includes a roller rotatably mounted between a pair of arms extending radially from a shaft detachably mounted to said at least one of said first and second link modules.
7. The conveyor chain as in claim 1 , in which said roller rotates about an axis of rotation, and said roller includes a surface defining a plane intersecting said axis of rotation.
8. The conveyor chain as in claim 1 , in which said roller rotates about a substantially vertical axis of rotation.
9. A link module for use in a conveyor chain intended for travel along an intended direction on a given path, said module comprising:
a first eye:
a second eye adjacent said first eye and defining a space therebetween; and
a roller assembly extending into said space and detachably mounted between said first and second eyes, wherein said detachable roller assembly includes a roller rotatably mounted on a spindle detachably mounted between said first and second eyes, and said spindle includes a stepped shaft having a first diameter and a smaller second diameter interposed between the first diameter and distal end of the shaft, said roller is rotatably mounted on the second diameter and abuts a step defining a boundary between said first and second diameters.
10. The link module as in claim 9 , in which a circumferential groove is formed in said second diameter proximal said shaft distal end for receiving a C-clip that axially locks said roller onto said shaft.
