An endless conveyor, particularly for the precision assembly and disassembly of parts, comprises a plurality of pivotally interconnected links at least one of which includes a block member having at least one longitudinally extending bore defined therethrough. Linear bearings are mounted in the block bore and a fixed longitudinally extending cylindrical guide rail is adapted to be engaged in the linear ball bearing within the bore so that the block member is supported on the guide rail during an upper horizontal movement of the block member. A guide member is disposed below and substantially parallel to the guide rail. First and second sprocket wheels are rotatably mounted on respective axes between the guide rails and the guide member beyond the respective ends thereof and rollers are provided on the block member for engaging the guide member during a lower horizontal movement thereof.
An endless conveyor particularly for the precision assembly and the disassembly of parts, comprising a plurality of pivotally interconnected links at least one of which includes a block member having at least one longitudinally extending bore defined therethrough, linear ball bearing means extending through said block bore, a fixed longitudinally extending cylindrical guide rail adapted to be engaged in the linear ball bearing means within said bore, said block member being supported on said guide rail during its upper horizontal movement therealong, a guide member disposed below and substantially parallel to said guide rail, first and second sprocket wheels rotatably mounted on respective axes between said guide rails and said guide member beyond the respective ends thereof, and roller means on said block member engageable on said guide member during the lower horizontal movement of said block member.
A conveyor link construction comprising at least one block shaped member having a bore therethrough, linear roller bearing extending through said bore providing a rolling guide for a guide mmember, at least one roller projecting laterally from said block member on each side thereof for supporting the sides of the block member on a guide, said block member having a forwardly and rearwardly extending link portion, each link portion having a pivot at the end thereof for pivotally interconnecting said link to a next adjacent link.
