A material storage and delivery structure and system having a first container storage rack for accumulating and storing full containers of parts, and a container indexing and transfer mechanism for delivering individual full containers from the first storage rack to an assembly line work station. The transfer mechanism is also operative to move empty containers from the work station to a second container storage rack for accumulating and storing empty or depleted containers. A full container loading station and an empty container unloading station are provided for delivering full containers to the first rack and removing empty containers from the second rack as desired. Movement of containers the loading station toward the transfer mechanism and from the transfer mechanism to the unloading station is effected by positive gravity flow rails disposed along each storage rack. The transfer mechanism also includes gravity flow rails to facilitate indexing of containers onto and from the storage racks. The full and empty container storage racks can be provided in over-under, under-over and side-by-side configurations. The system can also be provided in a closed loop configuration. Each of the configurations can be provided with side shuttle mechanisms for indexing and moving containers to and from intermediate work stations disposed laterally of individual storage racks.

Material storage and delivery system

An improved material flow rail construction of the type employed to transmit containers or articles from one location to another gravity force. The improved material fow rail comprises a substantially U-shaped channel within which a multiplicity of mounting bolts are attached. Individual bearing assemblies are placed on the mounting bolts. By placing the individual bearing assemblies closely adjacent one another in a longitudinal direction with respect to the support channel, the flow rail has the ability to transmit parts having very small 'footprint' areas since a large space between rollers is not presented for parts or components thereof to become caught. By providing a loose fit between the bearing inner races and the supporting mounting bolts, the inner race is permitted to rotate slightly with respect to the mounting bolts thereby presenting new wear surfaces as the flow rail is put into use. Additionally, such loose fit may be provided between the mounting bolts and the support channel to permit the latter to rotate with respect to the former, also presenting new wear surfaces.
