Patent number: 9517889Abstract: A conveyor belt and belt modules with plug-in accessories, such as sideguards. The accessories have plugs that plug into sockets in the belt or individual belt modules. Lugs and mounting slots and tabs and detents on the plugs and sockets help guide, register, and lock the accessories in place. The plugs and sockets allow the accessories to be locked and unlocked by twisting the plugs in the sockets.Type: GrantFiled: September 1, 2015Date of Patent: December 13, 2016Assignee: Laitram, L.L.C.Inventors: David W. Bogle, Terral A. Ridgell, Warren E. Cancienne, Jr.

Patent number: 9481523Abstract: A spiral conveyor for positively driving a conveyor belt (20) along a helical path. The spiral conveyor includes a rotating cylindrical tower (10) with parallel drive members (14) extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge (28) that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower. In another version, a conveyor belt has teeth (62) with guide surfaces (78, 79) at the inside edge of the belt. The teeth guide the drive members between belt rows into driving engagement with drive faces at the inside edge of the belt.Type: GrantFiled: July 8, 2011Date of Patent: November 1, 2016Assignee: Laitram, L.L.C.Inventors: Casper Fedde Talsma, David W. Bogle

Patent number: 9394109Abstract: A spiral conveyor for positively driving a hinged, modular conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the tower for engaging the inside edges of the belt. In one version, the ridges at the entrance end of the spiral are movable to provide a gradually decreasing spacing between consecutive ridges as the belt enters the spiral. In another version, alignment elements at the entrance end align belt-edge structure with the tip ends of associated ridges to help engagement. In another version, the ridges at a discharge end of the tower are retractable between an extended position driving the belt and a retracted position.Type: GrantFiled: March 12, 2013Date of Patent: July 19, 2016Assignee: Laitram, L.L.C.Inventors: Casper Fedde Talsma, David W. Bogle, Achraf Elhassouni, David A. Wickham

Patent number: 9334121Abstract: A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates that include openings for airflow and inner side plates that are solid to block airflow. The openings may include valves for selectively opening and closing the openings. A locking mechanism may lock two tiers together. A hold down may apply pressure to prevent destacking of the belt, or a guide may be disposed with the helical stack for preventing destacking.Type: GrantFiled: July 15, 2013Date of Patent: May 10, 2016Assignee: Laitram, L.L.C.Inventors: David W. Bogle, Alejandro J. Talbott, Robert L. Rosen

Publication number: 20160046447Abstract: A spiral conveyor and a method for taking up slack in a modular conveyor belt traveling a helical path. The spiral conveyor includes a rotating cylindrical drive drum with parallel drive members extending from the bottom to the top of the drum on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the drum for engaging the inside edges of the belt. A motor-driven take-up shaft and shaft-mounted sprocket set takes up slack in the belt after its release from the drum. To control tension at the discharge of the belt from the drive drum, the take-up motor is normally operated in a closed-loop control mode, but switches to an open-loop constant-speed control mode when the take-up motor stalls.Type: ApplicationFiled: April 22, 2014Publication date: February 18, 2016Inventors: David W. Bogle, Jonathan W. Mays

Patent number: 8397904Abstract: An environmentally controlled conveyor system including a sensor-instrumented conveyor belt conveying products continuously through a thermal-treatment process and a method for determining the instantaneous position of the sensors. Temperature or other sensors are embedded in the conveyor belt across its width and along its length to advance with the product through the thermal-treatment process, such as through a pasteurizer tunnel. The sensor measurements are transmitted wirelessly from the belt to a remote system controller for monitoring or controlling the system. Data from sensors measuring environmental or belt conditions are used to determine the instantaneous positions of the sensors to coordinate the sensor data with sensor position.Type: GrantFiled: April 10, 2012Date of Patent: March 19, 2013Assignee: Laitram, L.L.C.Inventor: David W.

Patent number: 8157083Abstract: A self-clearing conveyor transfer system for transferring articles between two mutually perpendicular conveyor belts. One version of the transfer system includes a finger transfer plate with fingers at one end extending into the end of a raised-rib belt and powered rollers at the opposite end rotating about axes perpendicular to the fingers. A second conveyor belt perpendicular to the raised-rib belt advances parallel to the roller axes. Articles transfer from one belt to the other across the finger transfer plate. Because the rollers are powered, straggling articles are not stranded on the transfer plate.Type: GrantFiled: December 23, 2009Date of Patent: April 17, 2012Assignee: Laitran, L.L.C.Inventor: David W.

Patent number: 7556136Abstract: A belt module with embedded rollers retained in cavities in the module by retention structure insertable into the module. The rollers and cavities are elongated in the direction of belt travel and closely separated by narrow dividers that form outward-facing surfaces that can serve as bearing surfaces for a belt made of the modules when the rollers are inactivated. When activated, the rollers, which rotate on axles parallel to the direction of belt travel, are supported directly on conveyor rolling surfaces. The dividers also carry the belt tension and stiffen the module.Type: GrantFiled: October 11, 2007Date of Patent: July 7, 2009Assignee: Laitram, L.L.C.Inventors: Angela L. Marshall, Brien G. Rau, David W. Bogle
