An apparatus for applying discrete components of a first substrate to a second substrate includes a programmable servo motor having a shaft. The servo motor is programmed to rotate the shaft in a first phase and a second phase at a variable angular velocity in a single direction. The apparatus also includes a crank member connected with the shaft, a connector link connected with the crank member, and a tamper member connected with the connector link. When the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component.

An ultrasonic welding system includes a motion control system that is coupled to and that causes controlled movement of an ultrasonic welding stack (10), in accordance with control inputs that are based on one or more control signals that are received from one or more sensors. The motion control system initiates a welding operation, subsequent to which an initial motion delay occurs until a predetermined condition is satisfied. Subsequently, in response to the predetermined condition being satisfied, the ultrasonic welding stack (10) is caused to move in accordance with a weld profile. Subsequently, in response to an occurrence of a predetermined delay initiating condition, the ultrasonic welding stack (10) is caused to stop motion and to maintain a stationary position. Subsequently, in response to an occurrence of a predetermined delay terminating condition, motion of the ultrasonic welding stack (10) is resumed in accordance with the weld profile.
摘要:
A packaging assembly, a packaging apparatus, and a process for packaging are disclosed which are configured to obtain a package where a tray (4) hosting the product (P) receives a plastic film sheet (18), comprising heat sealable material; the film sheet (18) is heat bonded to the tray top rim (4c) by at least by a seal (90) circumferentially extending between the peripheral portion (18b) and the top rim (4c) of the tray (4); at least one portion of the film sheet corner flap (93), overlapping the top rim (4c) of the tray (4) is not heat sealed to the same top rim.
摘要:
An apparatus for sealing an open end of a package comprises a first longitudinally extending sealing jaw, bearing mounted on a first eccentric shaft rotatable around a first rotational axis, and a second longitudinally extending sealing jaw, bearing mounted on a second eccentric shaft rotatable around a second rotational axis, the second sealing jaw being parallel with the first sealing jaw. At least one motor drives rotation around the first and second rotational axis in opposite directions, wherein the first and the second sealing jaws oppose each other, and are allowed to oscillate between sealing and open positions by moving towards and away from each other. A first and second transversally extending guiding bar cooperate with the first and second eccentric shaft via guiding pins running in guiding grooves, such that transverse play between the first and the second eccentric shaft and the first and second sealing jaw is allowed.
摘要:
A sealing machine adapted to support a plurality of different heating/sealing/cutting mechanisms, including tubular heaters and heated cutting blades, is disclosed. The sealing machine utilizes a common interface and mounting system for all side sealers. In addition, in some embodiments, the control system within the sealing machine is adapted to monitor and control the temperature of these various mechanisms automatically so as to create proper seals.
