Patent number: 5537930Abstract: During the haulage of a conveyor unit (3), a floor chain (6) of a shunting track (2) is moved over a pitch distance (PZ) which is slightly larger than the length of a conveyor unit (3) and which is selected such that, after the movement, a catch element (7) is in a position ready to carry along a pin (11) of a subsequent conveyor unit (3) to be hauled, until the conveyor unit (3) reaches an intermediate position whereby it is still situated with a portion thereof in the path (14) of the conveyor units (3) which have not been hauled. When the subsequent conveyor unit (3) must also be hauled, the floor chain (6) of the shunting track (2) is again moved over the above-mentioned pitch distance (PZ).Type: GrantFiled: March 8, 1995Date of Patent: July 23, 1996Assignee: Elektriciteit Voor Goederenbehandeling Marine En Industrie, in het verkort Egemin, naamloze vennootschapInventor: Carlos Van Lierde

Patent number: 5518102Abstract: A diverter for redirecting a single member or portion of a generalized set of material passing thereby. The device includes an electromechanical actuator which moves from an extended to a retracted position. A flexible strip has a first end attached to actuator and a second end fixed with respect to the actuator. The device is positioned proximate a gravity slide down which a stream of material moves in a first direction. When the actuator moves from its extended to its retracted position, the resilient strip flexes out into the path of the moving material. Any of the material striking the flexible strip will be deflected into a second direction which diverges from the first direction.Type: GrantFiled: November 7, 1994Date of Patent: May 21, 1996Assignee: Candid Logic Inc.Inventor: Bruce Hershline

Patent number: 5509537Abstract: A sorting machine for separating substandard items from a continuous stream of products is disclosed wherein the ejector that removes the detected substandard items includes an ejector finger and an actuator. The ejector finger includes a flexible elongate base member fixedly attached with respect to the product stream and a contactor normally withdrawn from the product stream when standard products are in the stream and for entering the product stream to eject a detected substandard item. The actuator flexes the flexible elongate base member to move the ejector contactor so that it enters the product stream for ejecting each detected substandard item. The flexible elongate base member make the ejector more resistant to wear from environmental conditions. A flexible sorting machine ejector mounting mechanism is also disclosed which removes costly mounting mechanisms.Type: GrantFiled: May 26, 1994Date of Patent: April 23, 1996Assignee: ESM International Inc.Inventors: James E. Crismon, Jerry W. Brum

Patent number: 5472185Abstract: A diverter for paper and cardboard sheets has upper and lower guide elements between the incoming conveyor and two outgoing conveyors including an acute angle with one another, constructed so that the upper and lower guide elements are pivoted respectively about horizontal axes above and below the travel path and links are pivotally connected to these guide elements spaced from their pivot axes so that a four-point linkage of the guide elements is provided. The upper guide element is driven by a pivot drive and entrains the lower guide element via the links.Type: GrantFiled: May 20, 1994Date of Patent: December 5, 1995Assignee: Jagenberg AktiengesellschaftInventors: Rolf Kollann, Armin Kloke

Patent number: 5452786Abstract: An apparatus and method for laterally diverting or shunting articles conveyed along a conveyor. An am or paddle is mechanically coupled to a rotating cam which drives the arm from a first or resting position parallel to the conveyor to a deflecting position across the conveyor at a first velocity profile and from the deflected position back to the resting position at a second, greater velocity profile in a single revolution of the cam. Velocity profiles can be optimized for the application by specification of the cam's geometry. Cycle times of 400 milliseconds, or 150 cycles per minute, are possible.Type: GrantFiled: July 19, 1994Date of Patent: September 26, 1995Assignee: Rapistan Demag CorporationInventor: Phillip J. Gilmore

Patent number: 5423409Abstract: An apparatus for forming a plurality of output rows from a single input row of articles has a conveyor advancing articles in a row parallel to the conveying direction; a deflecting device including an endless deflecting belt trained about two end rollers and having, when in a working position, an operative length portion forming an acute angle with the conveying direction. The deflecting member includes a first length portion provided with a bounding edge extending generally parallel to the conveyor surface and being at a clearance therefrom which is less than an expected minimum height of the articles positioned on the conveyor. The deflecting member further has a second length portion provided with a bounding edge extending generally parallel to the conveyor surface and being at a clearance therefrom which is greater than an expected maximum height of the articles positioned on the conveyor.Type: GrantFiled: April 4, 1994Date of Patent: June 13, 1995Assignee: SIG Schweizerische Industrie-GesellschaftInventor: Alfred Wipf

Patent number: 5419457Abstract: A system and a method for sorting are provided for distributing articles, such as mail pieces or other flats, to predetermined destinations. At the destination, the particular article is raked by a raking assembly from a carrier for placement into a container. The container, when full, is gravity fed onto a discharge conveyor and automatically replaced with a new empty container. The carrier operates on two levels for delivery of articles to containers on two levels while maintaining the carriers in a horizontal position throughout the sorting process. A sloped front end of the carrier allows the articles to be transported at a rapid speed and in a continuous fashion.Type: GrantFiled: August 30, 1993Date of Patent: May 30, 1995Assignee: ElectroCom Gard Ltd.Inventors: Gerald D. Ross, Robert E. Sadler, Jr., John M. Buday, Jr., Gunther A. Dorth, David Novak
