Appl. No.:

11/444869

Assignee:

JohnsonDiversey, Inc. - Sturtevant WI

International Classification:

A47L 15/46

US Classification:

222651, 222 52, 3405721, 340 101, 340 103

Abstract:

A dispensing system responds to reading data stored on a container by determining a dose for a chemical stored in that container. Then each time that the chemical is to be fed into a cleaning machine, the dispensing system operates a flow control device to deliver the designated dose. Thus the dispensing system is automatically reconfigured when different concentrations of the chemical are supplied to the dispensing system. Various mechanisms for storing the data on and reading the data from the container are described.

Abstract:

A system controls dispensing different chemicals received from containers at a plurality of ports. Each container has data thereon that identifies the chemical within the container. The system reads the data from each container to determine which port is associated with each chemical. When a given chemical is required, the system activates a flow control device coupled to the port associated with that given chemical, thereby supplying the given chemical to a consuming device. Therefore regardless of into which port an operator places a particular chemical, the system automatically knows which port has which chemical and the dispensing is configured accordingly. Various mechanisms for storing the data on and reading the data from the container are described.
