Patent number: 8454487Abstract: The invention relates to a separation disc and a milk separator comprising a rotor, which separation disc together with other separation discs forms a stack of separation discs rotatable together with the rotor. The separation disc comprises a truncated substantially conical portion and an annular flange element connected to the conical portion at the smallest radius and extends therefrom radially inwards substantially perpendicular to the axis of rotation. The flange element has a radial extent corresponding to at least 10% of the radial extent of the conical portion. The inner radial edge of the flange element includes recesses distributed along the edge and adapted to protrusions on a column connected to the rotor, extending coaxially through the separation discs. The recesses are substantially filled by the protrusions. The radial extent of the recesses corresponds to at least 20% of the radial extent of the flange element.Type: GrantFiled: April 7, 2009Date of Patent: June 4, 2013Assignee: Alfa Laval Corporate ABInventors: Per-Olof Lindroth, Johan Bergstrom, Jan Ackalin

Patent number: 7096571Abstract: A method of transferring component tape information to a component mounting machine, a tape guide for guiding a component tape in a component mounting machine, and a tape magazine for receiving the tape guide. The tape guide is arranged for quick and ready attachment and detachment into and from the component mounting machine. The loading and/or unloading of a component tape into and from the tape guide can be performed away from the component mounting machine. The ability to be releasably mounted is achieved by providing the tape guide with a lock that enables ready and quick attachment and detachment to an interacting lock in a component mounting machine, or in a tape magazine arranged for insertion into a component mounting machine, and a guide for guiding the component tape. The tape guide further includes an identifier for holding the identity of the tape guide, which can be associated with information relating to the component tape.Type: GrantFiled: September 2, 2003Date of Patent: August 29, 2006Assignee: Mydata Automation ABInventor: Johan Bergström

Patent number: 6948541Abstract: System for handling components in connection with circuit board assembly in a component mounting machine. The system comprises a number of component tapes provided on component tape reels, and a number of tape guides arranged for receiving component tapes of a given component tape width and for bringing the component tape in position for feeding of the component tape and for picking components from the component tape in the component mounting machine. The tape guides have a similar geometrical outline and basic configuration, and each tape guide comprises a component exposure device for exposing a component at a picking position by removing the portion of the cover tape covering the component. The tape guides are divided into sub-sets of tape guides, wherein the tape guides of each individual sub-set have component exposure devices of the same design, which design is dependent on the configurations of the component tapes intended for that sub-set of tape guides.Type: GrantFiled: July 7, 2004Date of Patent: September 27, 2005Assignee: Mydata Automation ABInventors: Johan Bergstrom, Maria Liljegren, Johan Skaborn
