  • Patent number: 7818089
    Abstract: Confectionary image design system including a graphical user interface through which a user defines a pattern of confectionary pieces to be arranged on a substrate. A computer processor controls the graphical user interface through which the user defines the pattern, and provides instructions for arranging the confectionary pieces in the defined pattern. A container retains the confectionary pieces used to form the defined pattern. A robot receives from the computer processor the instructions for arranging the confectionary pieces, retrieves the confectionary pieces stored in the container, and arranges the pieces on the substrate in the pattern defined by the user.

  • Patent number: 6786987
    Abstract: A method and apparatus are provided for sealing packaging material using ultrasonic technology. The method includes the steps of supplying the packaging material to a sealing station that includes an anvil and horn, and sealing the packaging material. The apparatus is a cam-shaped, rotatable anvil where the rate of rotation of the anvil can be changed based upon the speed of an AC Servo driving the anvil and the desired spacing between the seals.

  • Patent number: 6732498
    Abstract: A piece count and collation system includes a cut-and-seal apparatus including a pair of rotatable members positioned immediately adjacent each other for receiving a tube wrapping containing a plurality of sequentially spaced objects. The rotatable members rotate in opposite directions to one another and each includes a first cutting edge having a first bonding surface positioned immediately adjacent thereto and a second cutting edge spaced apart from the first cutting edge and having a second bonding surface positioned immediately adjacent thereto. At least one of the rotatable members includes a vacuum grasping member positioned between the first and the second cutting edges for grasping one of said plurality of sequentially spaced objects in the tube wrapping received by the cut-and-seal apparatus while the tube-wrapping is cut and bonded on both ends to form a fully wrapped object.

  • Publication number: 20030217531
    Abstract: A vertical form, fill, and seal apparatus for making different types of packages is provided. The packaging material travels around the outside, and the product goes through the inside, of the form-and-fill tube. A fin sealing mechanism, pleat sealing mechanism, and horizontal sealing mechanism are used in combination to make the different types of packages.

  • Publication number: 20030097815
    Abstract: A modular apparatus is provided for the purpose of packaging an article in a special wrap (such as a single or double twist wrap, an envelope wrap, a bunch wrap, or other special wrap). The modular apparatus has a receiving portion, arranged to receive a partially-wrapped article (such as a tube-wrapped article) into a predetermined location, from another machine, and a special-wrap assembly that forms the desired special wrap. For a double twist-wrap, the special-wrap assembly has rotatable twist grippers that grip the ends of the tube-wrapped article, and twist the ends to form a twist-wrapped article, and includes a twist-wrap drum and Geneva wheels that drive the twist grippers. The modular apparatus is used with a flow-wrap packaging line for wrapping a series of individual articles, which has a first section, in which a film is formed into a tubular wrap about the articles, and a cut-and-seal section, in which the tubular wrap is cut between each two successive articles.

  • Patent number: 6264591
    Abstract: A cigarette filter rod system comprises a plug combiner machine having a knife located downstream from a sensor. The knife generates a trigger signal which prompts an Inspection Unit to locate a previously stored frame of sensor data corresponding the rod which was cut by the knife. The Inspection Unit applies thresholds to the frame of sensor data to determine the location of filter segment boundaries, and then determines whether air rings are present in the data. The Inspection Unit then compares measurements made on the frame of sensor data with a pre-stored recipe indicating expected values for the frame. Statistical data is sent to a Human-Machine Interface Unit for analysis and display. The system performs filter rod rejection and cut registration based on the analysis performed by the Inspection Unit and the Human-Machine Interface.
