Patent number: 11878829Abstract: A packaging machine is provided for producing single and multiple compartment film wrapped pouches. Multiple linear motors allow aspects of the forming, filling, cutting and discharging to run at different speeds. The pouches are formed, filled and discharged from platens that are secured to movers that proceed through the packaging process by following magnetic fields created by independently controlled linear motors. Overall, cycle time is decreased as a result of speeding up parts of the process, including the platen return process, possible because there is no mechanical connection and not a single conveyor moving the platens while the other parts of the process may be simultaneously slowed down or even temporarily stopped. Changeover of platens, to accommodate different products, such as single compartment pouch to multiple compartment pouches, is also simplified because platens are simply connected to the movers and are thus easily removed and replaced.Type: GrantFiled: December 9, 2022Date of Patent: January 23, 2024Assignee: NEW SPS POD, LLCInventors: Thomas M.
