Publication number: 20100108469Abstract: A moving device comprises at least a first element which is movable in a direction of movement by means of a drive unit, which first element at least comprises at least one first magnetic part. The moving device further comprises a second element, with respect to which the first element is movable at least from at least one operative position spaced from the second element to a rest position near the second element. The second element comprises at least one second magnetic part, which is polarized in a polarization direction opposed to the polarization direction of the first magnetic part. The polarization directions extend transversely to the direction of movement and also transversely to surfaces of the first and second elements that are positioned opposite each other in the rest position.Type: ApplicationFiled: October 28, 2009Publication date: May 6, 2010Applicant: Assembleon B.V.Inventor: Martinus Cornelis Ophey

Publication number: 20100059339Abstract: A transfer apparatus includes a primary part, and at least one first and one second secondary part, which are each magnetically coupled to the primary part for drive purposes. A regulation device is provided for regulation of a drive of the secondary parts. The regulation device can regulate the drive of the first secondary part in a first zone of the primary part in accordance with a first regulation rule, and can regulate the drive of the second secondary part in a second zone of the primary part in accordance with a second regulation rule. The first and second regulation rules differ hereby from one another. The first zone is separated from the second zone by a boundary which can be varied dynamically by the regulation device.Type: ApplicationFiled: September 9, 2009Publication date: March 11, 2010Applicant: Siemens AktiengesellschaftInventor: JOHANN HOFRICHTER

Patent number: 7597187Abstract: A conveyor system has an elongated guide defining a closed transport path extending through a plurality of treatment stations and a plurality of carriers movable on the guide along the path and each capable of holding a respective workpiece. At least one magnet is provided on each carrier, and an annular row of individually energizeable electromagnets extends along the path and is capable of exerting force on the magnets of the carriers so as to displace the respective carriers along the path. A plurality of sensors spaced along the path detect the carriers and generate outputs indicating positions and movement of the carriers along the path. At least some of the electromagnets at least intermittently form some of the sensors.Type: GrantFiled: March 26, 2008Date of Patent: October 6, 2009Assignee: KBA-Metronic AGInventors: Alfred Bausenwein, Peter Schmitt

Patent number: 7594654Abstract: A sheet conveyor includes a conveyor belt that conveys a sheet material while holding the sheet material by attraction with an electric force, and a platen that slidably supports a bottom surface of the conveyor belt so as to maintain flatness of a predetermined region of the conveyor belt. In response to the electric force, an attractive force for attracting the conveyor belt to the platen is generated. The platen is shaped such that a surface of the platen that is in contact with the conveyor belt has a width that increases gradually from an upstream side of the platen towards a downstream side thereof in a conveying direction of the conveyor belt.Type: GrantFiled: May 4, 2006Date of Patent: September 29, 2009Assignee: Canon Kabushiki KaishaInventor: Tadashi Matsumoto

Patent number: 7575406Abstract: A semiconductor workpiece processing apparatus having a first chamber, a transport vehicle, and another chamber. The first chamber is capable of being isolated from an outside atmosphere. The transport vehicle is located in the first chamber and is movably supported from the first chamber for moving linearly relative to the first chamber. The transport vehicle includes a base, and an integral semiconductor workpiece transfer arm movably mounted to the base and capable of multi-access movement relative to the base. The other chamber is communicably connected to the first chamber via a closable opening of the first chamber. The opening is sized to allow the transport vehicle to transit between the first chamber and the other chamber through the opening.Type: GrantFiled: July 22, 2003Date of Patent: August 18, 2009Assignee: Brooks Automation, Inc.Inventors: Christopher Hofmeister, Robert T.

Publication number: 20090139839Abstract: A transport system for conveying sheet material along a feed path. The transport system includes an electro-dynamic propulsion system for moving sheet material, or a stacked collation of sheet material, along a support deck which defines the feed path. More specifically, the electro-dynamic propulsion system includes at least one guideway and a ferromagnetic element disposed internally of the guideway. The guideway includes a magnetic coil to produce a variable magnetic field. By varying the flux density and polarity of the magnetic field the ferromagnetic element may be propelled within the guideway. An abutment member is coupled to the ferromagnetic element, extends through the elongate opening of the support deck and engages an edge of sheet material. A processor is operative to control the electro-dynamic propulsion system and, accordingly, the rate of travel and position of the sheet material along the feed path.Type: ApplicationFiled: November 30, 2007Publication date: June 4, 2009Applicant: Pitney Bowes Inc.Inventor: Henson C.

Patent number: RE41760Abstract: A magnetic sample rack adapted to support liquid containers is urged along a surface by means of a magnetic conveyor system located beneath the surface. The magnetic conveyor system comprises a plurality of magnetic housings driven by a belt, the magnetic housings including a magnet slideably contained in a closed upper cavity. Magnetic forces emanating from the magnet overcome frictional resistive forces between the sample racks and the operating surface and move the sample racks along input and output lanes defined in the operating surface. Abrupt movements of the sample racks are eliminated because the housing magnet slides smoothly towards the sample rack, secures the sample rack, and pulls the rack along the operating surface as the housings are moved at a steady rate by the belt.Type: GrantFiled: January 19, 2005Date of Patent: September 28, 2010Assignee: Siemens Healthcare Diagnostics Inc.Inventors: David R. Thompson, Tumkur R. Vijay, William D. Dunfee, Daniel E. Gillund
