Abstract
The ultrasonic sealing device (50) may be integrated on a packaging machine (20) such as a TETRA REX.RTM. packaging machine and used for sealing one end of a carton (200). The ultrasonic sealing device (50) includes a frame (52), an anvil (56), a horn (54) and a plurality of adjustable shafts (60-65). The anvil (56) is disposed on one side of a carton pathway (32) and moveably attached to the frame (52). The ultrasonic horn (54) is disposed on another side of the carton pathway (32) opposite the anvil (56) and moveably attached to the frame (52). The plurality of adjustable shafts (60-65) includes a first plurality of adjustable shafts (60,61) connected to the frame (52), and allowing for vertical adjustment of the frame (52) relative to the carton pathway (32). It also includes a second plurality of adjustable shafts (62,63) connected to the frame (52) and allowing for transversal adjustment of the frame (52) relative to the carton pathway (32). Yet further, the plurality of adjustable shafts (60-65) includes a third plurality of adjustable shafts (64,65) connected to the frame (52) and allowing for horizontal adjustment of the frame (52) relative to the carton pathway (32). A cooling jaw assembly (100) is disposed subsequent to the ultrasonic sealing device (50) for cooling of a carton (200) after sealing of one end thereof.
