Patent number: 6918238Abstract: An externally installable and removable bearing and shaft assembly for supporting an end of a rotatable member for rotation relative to a support member or structure, which when installed, applies an axial preload force against a shaft of the assembly, for reducing the occurrence of flexure or bending of the shaft due to side loads during the rotation which can lead to fatigue failure including shaft breakage.Type: GrantFiled: July 21, 2003Date of Patent: July 19, 2005Assignee: CNH America LLCInventors: William L. Cooksey, Herbert M. Farley

Patent number: 6907984Abstract: A motor mounting configuration for a roll out table reduces bearing wear and allows the motor of the roll out table to be quickly removed and reinstalled. A method for retrofitting a roll out table with a motor mount configuration that allows the motor to be quickly removed and reinstalled includes the use of a hold down element. In addition, the retrofit roll out table includes a bearing configuration designed to better withstand the harsh operating environment of the roll out table. Further, the improved roll out table includes a coupling between the motor and the roller shaft that allows for adjustability.Type: GrantFiled: April 2, 2002Date of Patent: June 21, 2005Assignee: The Hannon CompanyInventors: John W. Cespedes, Thomas E. Besco, Steven R. Harper, Jeffery A. Smith, Joseph A. Trescott, Timothy F. Hannon

Patent number: 6871850Abstract: The invention concerns an apparatus and a method of tensioning a flat web of material to be conveyed, in particular in a printing and dispensing device for labels, which includes: a drive for advancing and retracting the flat web of material, and at least one advance unit and at least one braking unit having a braking roller which are in contact with the web of material and which are drivable by the drive means. It is further provided that the drive has a drive motor that is drivingly connected to the advance unit and the braking unit and that, in a conveyor operation in the advance direction of the web of material, the braking roller of the braking unit is uncoupled from the drive motor.Type: GrantFiled: May 5, 2000Date of Patent: March 29, 2005Assignee: Avery Dennison CorporationInventor: Johannes Lenkl

Patent number: 6868961Abstract: A roller conveyor which includes idler rollers which are drivable in a driving direction in response to rotational driving of a drive portion of the rollers, and which are freely rotatable in the driving direction relative to the drive portions of the rollers, in order to allow for coasting of articles or products on the roller conveyor. The rollers include one-way clutch devices which may drive the rollers in the driving direction in response to activation or engagement of a drive means to convey products along the conveyor. The clutch devices also allow the rollers to continue to rotate in the driving direction after the driving means has been deactivated or disengaged from the rollers. The roller conveyor thus may convey articles along multiple zones of the conveyor and may accumulate articles on the zones, such as in response to article sensors positioned along the roller conveyor.Type: GrantFiled: April 3, 2003Date of Patent: March 22, 2005Assignee: Rapistan Systems Advertising Corp.Inventors: Ronald C. Ehlert, Kenneth J. Kooistra

Patent number: 6867702Abstract: A freight-loading system in a cargo hold of an aircraft is provided that offers enhanced operating safety. The freight-loading system comprises a plurality of power drive units (PDUs), which can be actuated by control signals in such a way that items of freight can be maneuvered into or out of the cargo hold as well as within it. The power drive units (PDUs) are connected by control leads to control panels for actuation by personnel. A control maintenance computer (CMC) is provided and connected to the power drive units (PDUs) and the control panels, and is so designed that status information from the power drive units (PDUs) and the control panels can be read out, and that the power drive units (PDUs) and/or the control panels are controllable by the control maintenance computer (CMC).Type: GrantFiled: March 19, 2003Date of Patent: March 15, 2005Assignee: Telair International GmbHInventors: Thomas Huber, Benedikt Kieser, Matthias Urch, Thomas Perreiter, Stefan Auer

Patent number: 6854592Abstract: A roller conveyor has three-phase synchronous motors and feed rollers. The three-phase synchronous motors are operationally coupled to the respective feed rollers. The three-phase synchronous motors are driven by a three-phase AC voltage supplied from a three-phase AC power supply and the three-phase synchronous motors output a torque. Each feed roller is caused to roll to convey a work by the torque output from the corresponding three-phase synchronous motor. This structure provides an inexpensive roller conveyor which is easy to maintain.Type: GrantFiled: August 25, 2003Date of Patent: February 15, 2005Assignee: Watanabe Machinery Mfg. Co., Ltd.Inventor: Mitsuhiro Fukuoka

Patent number: 6808063Abstract: A motor-installed roller (3) has a roller body (6) and a prime mover unit (35) installed in this body and composed of a motor (33) and a reducer (34). The roller body (6) has opposite ends closed with closures (7) serving as closures and having cavities (22) formed in it. An external force is applied to an area of outer periphery of the roller body (6), the area corresponding to and facing each cavity (22) so as to plastically deform portions of the roller body and the closure (7). A punched hook engagement (65) formed in this manner serves to easy consolidation of the closure (7) such as the closure, a bearing or the like and the roller body (6) into the motor-installed roller (3), in which they are protected from moving relative to each other in tangential and axial directions, also inhibiting the closure (7) from slipping off even if subjected to vibration.Type: GrantFiled: January 21, 2003Date of Patent: October 26, 2004Assignee: Itoh Electric Company, LimitedInventors: Kazuo Itoh, Kazuaki Kobayashi
