Reciprocating sealer for web converters

摘要

Various device embodiments perform a sealing operation on a moving web, and comprise, among other things a plate assembly with an air cylinder assembly. The air cylinder assembly comprises a mount, a back plate, at least one air cylinder positioned between the mount and the back plate. The first plate assembly further includes a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, and a first tooling plate with a sealing surface area. The first tooling plate coupled to the back plate.

1. A device for performing a sealing operation on a moving web, the device comprising:
a first plate assembly comprising,
a first base,an air cylinder assembly connected to the first base, the air cylinder assembly comprising:
a mount having a periphery,a back plate,two air cylinders positioned between the mount and the back plate,wherein the mount has two approximately equal air cylinder areas, and one the air cylinders is approximately centered in one of the air cylinder areas and the other of the air cylinders is approximately centered in the other of the air cylinder areas,a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, anda first tooling plate with a sealing surface area, the first tooling plate coupled to the back plate; a second plate assembly comprising,
a second base,a second tooling plate, anda linear servo motor for linearly moving the second tooling plate with respect to the second base; at least one plate assembly motor operably linked to the first base and the second base to provide a linear motion of the first and second plate assemblies toward each other during the sealing operation on the moving web and away from each other after the sealing operation.
