The system is primarily comprised of a conveyor section, for receipt of a bulk flow of articles and conveyance of spaced apart metered article groups downstream of an ingress portion thereof, and an article metering station characterized by an article metering apparatus characterized by a drive assembly and a driven member driven thereby. The driven member includes an end effector for select positioning between adjacent articles of articles of the bulk flow of articles received by the conveyor section in furtherance of delimiting a downstream spaced apart metered article group characterized by a select number of columns. The drive assembly includes cooperatively driven servo drives to effectuate travel of the end effector in either of a downstream article flow direction or an upstream article flow direction, and an up/down direction in relation to articles of the bulk flow of articles received by the conveyor section. ## Claims ### Claim 1 An article metering system comprising: a. a conveyor section for receipt of a bulk flow of articles characterized by at least a single row of articles at a ingress portion thereof, and for conveyance of spaced apart metered article groups downstream of said ingress portion; and, b. an article metering station characterized by an article metering apparatus comprising a drive assembly and a driven member driven thereby, said driven member including an end effector for select positioning over and thereafter down and between adjacent articles of articles of the bulk flow of articles received by said conveyor section in furtherance of delimiting a downstream spaced apart metered article group characterized by a select number of columns, said drive assembly comprising cooperatively driven servo drives to effectuate travel of said end effector in either of a downstream article flow direction or an upstream article flow direction, and an up/down direction in relation to articles of the bulk flow of articles received by said conveyor section, at least one servo drives of said cooperatively driven servo drives supported at an elevation not greater than an elevation of a conveyor surface of said conveyor section. ### Claim 2 (depends on 1) The article metering system of claim 1 further comprising a surge feedback control, load monitoring and/or sensing undertaken in connection to said drive assembly of said article metering apparatus with control of a conveyor of said conveyor section selectively effectuated by said surge feedback control in response to said load monitoring and/or sensing. ### Claim 3 (depends on 1) The article metering system of claim 1 wherein said article metering apparatus includes a load sensing/monitoring element for sensing/monitoring article surge associated with article accumulation during select positioning of said end effector between adjacent articles of articles of the bulk flow of articles conveyed by said conveyor section. ### Claim 4 (depends on 1) The article metering system of claim 1 wherein said article metering station is characterized by a further article metering apparatus, said further article metering apparatus synchronously operated in relation to said article metering apparatus. ### Claim 5 (depends on 1) The article metering system of claim 1 wherein said article metering station is characterized by a further article metering apparatus, said further article metering apparatus positioned across from said article metering apparatus. ### Claim 6 (depends on 1) The article metering system of claim 1 wherein said article metering station is characterized by a further article metering apparatus, a first metered article group of sequential formed metered article groups delimited by said article metering apparatus, a second metered article group of sequential formed metered article groups delimited by said further article metering apparatus. ### Claim 7 (depends on 1) The article metering system of claim 1 wherein said ingress portion of said conveyor section includes a retractable transfer device, a downstream most portion of the bulk flow articles selectively supported and conveyed at a bulk flow velocity, retraction of said retractable transfer device transferring an article group to a conveyor of said conveyor section having a velocity greater than the bulk flow velocity so as to effectuate formation of a spaced apart metered article group. ### Claim 8 An article metering system comprising: a. a conveyor section for receipt of a bulk flow of articles characterized by at least a single row of articles at a ingress portion thereof, and for conveyance of spaced apart metered article groups downstream of said ingress portion; and, b. an article metering station characterized by an article metering apparatus comprising a drive assembly and a driven member driven thereby, said driven member including an end effector for select positioning over and thereafter down and between adjacent articles of articles of the bulk flow of articles received by said conveyor section in furtherance of delimiting a downstream spaced apart metered article group characterized by a select number of columns, said drive assembly comprising cooperatively driven servo drives to effectuate travel of said end effector in either of a downstream article flow direction or an upstream article flow direction, and an up/down direction in relation to articles of the bulk flow of articles received by said conveyor section, servo drives of said cooperatively driven servo drives underlie a conveyor surface of said conveyor section. ### Claim 9 An article metering apparatus for metering a bulk flow of articles conveyed upon a conveyor into an article group, the metering apparatus comprising a drive assembly and a driven member driven thereby, said driven member including an end effector for select positioning relative to select adjacent articles of articles of the bulk flow of articles conveyed upon the conveyor in furtherance of delimiting a downstream spaced apart metered article group characterized by the select number of articles columns, said drive assembly comprising paired rotating servo drive mechanisms and a set arms characterized by arm segments, each arm of said set of arms joining each rotating servo drive mechanism of said paired rotating servo drive mechanisms to said driven member, said end effector positionable to overly the bulk flow of articles such that a tool of said end effector is selectively introduced into the bulk flow of articles from above so as to delimit the select number of article columns for the at least single row of articles.
