Sealing station for sealing of film bags and corresponding method
10793306 · 2020-10-06 · ·

The invention relates to a sealing station in a film bag filling device for sealing of film bags after a filling process, wherein the sealing station comprises a first and a second sealing arm for sealing of several filled film bags that are arranged next to one another, wherein the first sealing arm is moveable with a first drive shaft and the second sealing arm with a second drive shaft. A servo engine is disposed on the first drive shaft, and a drive movement of the first drive shaft from a first gear wheel is transferred to a second gear wheel that encroaches in the first gear wheel and from the second gear wheel to the second drive shaft. The invention further relates to a method for sealing of film bags after a filling process with the sealing station according to the invention with the following steps: positioning of filled film bags below the sealing station; closing of the sealing arms and application of a contact pressure with a first value and sealing of the filled film bags.

Flexible jaws for vertical fill form and seal apparatus and methods of use

A vertical form fill and seal apparatus, for packaging particulates, includes a package sealing assembly that has opposed sealing jaws operatively coupled to each other by mechanical connection at a common pivot point. A first jaw actuator is mechanically coupled to the opposed sealing jaws to pivot the jaws in a controlled manner about the common pivot point. A second actuator is mechanically coupled to the package sealing assembly and is configured to impart controlled reciprocating motion to the package sealing assembly. A controller is configured to control the first actuator and to control the second actuator thereby causing the jaws to describe a preset locus of travel, allowing flexibility of type of bag being made without change-out of jaws. The packaging film may move continuously, or may optionally be controlled to move intermittently through the VFFS.
