Modular link conveyor with features for enhancing the efficient conveyance of articles
An apparatus for conveying an object in a conveying direction includes a conveyor comprised of a plurality of modular links adapted for interconnecting to form a chain. At least one of the links comprises a rounded upper portion forming an apical region for contacting and supporting the article for conveyance along at least a forward run in the conveying direction. The at least one link further including a forwardly projecting portion associated with a first transverse connector forming a part of the upper portion and a rearwardly projecting portion associated with a second transverse connector forming part of the upper portion. The first and second connectors may be staggered in the conveying direction and a direction transverse to the conveying direction. Further aspects pertain to a link with an apical engaging structure, and a sprocket with a removable tooth.
1. An apparatus for conveying an object in a conveying direction, comprising:
a conveyor including a plurality of modular links adapted for forming a chain, at least one of the links comprising a rounded upper portion for contacting and supporting the object for conveyance along at least a forward run in the conveying direction, the at least one link further including a forwardly projecting portion associated with a first transverse connector, a rearwardly projecting portion associated with a second transverse connector, the first and second connectors being non-collinear;
wherein the first and second connectors contact and support the object for conveyance.
2. The apparatus of claim 1 , wherein the first connector includes a first apical region and the second connector includes a second apical region.
3. The apparatus of claim 2 , further including a third connector including a third apical region, the third connector being collinear with either the first connector or the second connector.
4. The apparatus of claim 1 , wherein at least one of the links includes a portion for engaging a drive structure, the portion comprising an apical surface.
5. The apparatus of claim 4 , wherein the portion comprises a depending arm including the apical surface.
6. The apparatus of claim 4 , wherein the apical surface is provided by a spherical cap.
7. The apparatus of any of claim 4 , wherein the drive structure comprises a tooth of a sprocket.
8. The apparatus of claim 7 , wherein the sprocket comprises a sprocket body including one or more removable teeth for forming the drive structure.
9. The apparatus of claim 1 , wherein the at least one link comprises a side link, and further including another link forming a row of the chain and connected to the side link by the connector.
10. The apparatus of claim 1 , further including a connector rod for interconnecting adjacent rows of links to form the chain.
11. The apparatus of claim 1 , wherein the at least one link includes an upstanding wall for confining the object on the upper portion.
