摘要:
A method and an apparatus for ultrasonic staking a first part having a fastening portion to a second part having an opening corresponding to the fastening portion. The method comprises aligning the fastening portion of the first part with the corresponding opening in the second part, inserting a head of the fastening portion through the corresponding opening, and causing a horn of an ultrasonic staking stack to contact the head, apply ultrasonic energy oscillating at a frequency between 45 kHz and 75 kHz, and move along an axis of the fastening portion as the head melts to form a stake. The stake can include a melt-form that joins the first part and the second part to each other, and the fastening portion can have a geometry or a size disposed to flapping.

A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.

Apparatus and methods for effecting ultrasonic bonds in sequentially advancing workpiece segments, in a nip defined by a rotary ultrasonic horn and rotary anvil roll. The ultrasonic bonding apparatus comprises support structure comprising anvil support apparatus and horn support apparatus. A closed loop control apparatus is connected to one or both of the anvil support apparatus and horn support apparatus. The closed loop control apparatus comprises a programmable logic controller, a load cell, and an adjustor. Information output from the load cell triggers the closed loop control apparatus through the programmable logic computer and the adjustor to move one or both of the anvil support apparatus and horn support apparatus toward or away from the other in dynamic response to the information output from the load cell, thereby regulating pressure in the nip with ongoing real-time adjustments to distance between the anvil support apparatus and the horn support apparatus.

This invention pertains to apparatus and methods for creating ultrasonic bonds in sequentially advancing absorbent article workpiece segments, in a bonding nip. The ultrasonic bonding apparatus comprises a frame, anvil support apparatus, horn support apparatus, closure apparatus, a load cell support member, and a load cell. The ultrasonic horn and the anvil roll collectively are mounted and configured such that the ultrasonic horn and the anvil roll can be brought together, via the closure apparatus, to define the nip therebetween. The load cell is mounted to the load cell support member such that force representative of force exerted on the anvil roll at the nip is detected by the load cell. In preferred embodiments, the invention includes outputting information from the load cell and adjusting force in the nip in response to the information received from the load cell.

A method and system for ultrasonic sealing of food product packaging is provided. The ultrasonic sealing system preferably includes a food product packaging-positioning system that delivers food product packaging and food product into direct on-item-packaging forming box. The direct on-item-packaging forming box then receives the food product packaging and forms it directly around the supplied food product forming a partially packaged food product. The partially packaged food product is then ultrasonically edge sealed around the food product by an ultrasonic food product packaging fin-sealing unit forming a partially sealed food product packaging. The partially sealed food product packaging then enters a food product packaging end-sealing unit which ultrasonically seals and crimps the ends of the food product packaging resulting in a fully packaged and ultrasonically sealed food product.
