A monitoring and control system for a fluid container filler line having an empty container in-feed conveyor (11), a multivalve fill station (14), a multihead scanner station (17), a discharge conveyor (20) and a fill height detector (25), the system comprising a sensing module (22) having a first s

A monitoring and control system for a fluid container filler line having an empty container in-feed conveyor (11), a multivalve fill station (14), a multihead scanner station (17), a discharge conveyor (20) and a fill height detector (25), the system comprising a sensing module (22) having a first sensor (44) to indicate the first of a sequence of numbered valves with means to reset a valve counter, a second sensor (45) to count each valve of the sequence and controller means (50) responsive to said sensors to spacially track each container (12) through the system and to identify the particular fill valve for each particular container. A detector (54) is responsive to the controller and signals from the height detector to detect an improperly filled faulty container and identify the particular number valve which did the faulty filling. The invention also includes detection of faulty seamer operation, means to automatically sample containers for test purposes and means to prevent an incoming container from taking a position to be filled by a faulty valve. Means are also included to analyze the flow of containers and the quality of filling and predict line fill losses attributable to faulty valves which information is used to decide if a faulty valve shall be rendered inoperative.

A monitoring and control system for a fluid container filler line having an empty container in-feed conveyor, a multi-valve rotary fill station, a multi-head seamer station to close and seal the then filled containers, a discharge conveyor and a fill height detector for under and overfill detection

A monitoring and control system for a fluid container filler line having an empty container in-feed conveyor, a multi-valve rotary fill station, a multi-head seamer station to close and seal the then filled containers, a discharge conveyor and a fill height detector for under and overfill detection of liquid within said containers, said monitoring and control system comprising: (a) first sensor means located for indicating a first valve of a sequence of numbered fill valves in said fill station, a valve counter, and means for resetting said valve counter to 1 each time increment that said first valve passes said first sensor means; (b) second sensor means located for counting each valve of the sequence to fill valves; a signal from said second sensor means for advancing said valve counter; (c) controller means responsive to said first and second sensor means and said valve counter for spacially tracking each of said containers through said system and for identifying a particular fill valve for each particular container; (d) detector means responsive to said controller means and fault signals from said fill height detector for detecting an improperly filled faulty container and the particular numbered valve which filled said faulty container; and (e) means responsive to detection of improperly filled faulty containers for preventing a container on said infeed conveyor from being positioned in said filter station at a numbered valve of said fill station which has been detected as being faulty.
