20090095599 | CONVEYOR BELT MODULE WITH RETAINED ROLLERS - 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. | 04-16-2009 |
20110147162 | SELF-CLEARING CONVEYOR TRANSFER SYSTEM AND TRANSFER PLATE - 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. | 06-23-2011 |
20120217138 | BELT CONVEYORS AND METHODS FOR CONVEYED PRODUCTS UNDERGOING A THERMAL TREATMENT - 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. | 08-30-2012 |
20130206545 | SYSTEM AND METHOD FOR DETECTING CONTAMINATION OF A CONVEYOR - Conveying systems and method for detecting the presence and amount of biological contaminants or additives on a conveyor belt. The conveyor system includes a conveyor belt having embedded biosensors. Transmitters co-located in the belt with the biosensors transmit biosensor signals to a remote controller. The remote controller allows remote monitoring of the contamination level on the conveyor belt. | 08-15-2013 |
20130213773 | POSITIVE-DRIVE SPIRAL CONVEYOR AND BELT - A spiral conveyor for positively driving a conveyor belt ( | 08-22-2013 |
20130306445 | CONVEYOR BELT AND MODULE WITH MAGNETS - A modular radius conveyor belt having magnetic material in adjacent belt rows, including magnets in selected rows of belt modules. Magnets in one belt row attract magnets or paramagnetic material in adjacent rows to prevent vibration between rows that could shake a conveyed article out of its preferred position or orientation on the conveyor belt. | 11-21-2013 |
20140021020 | SELF-STACKING SPIRAL MODULAR PLASTIC CONVEYOR BELT - 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. | 01-23-2014 |
20140158497 | BULK-PRODUCT CONVEYOR WITH SENSOR - A conveyor belt having a sensor probe extending upward from an outer conveying surface into a mat of bulk products conveyed on the belt. The probe senses a condition of the product mat at a predetermined depth. The probe height above the conveying surface may be fixed or may be adjustable to be positioned at a critical depth within the product mat. | 06-12-2014 |
20150047952 | POSITIVE-DRIVE SPIRAL CONVEYOR - 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. | 02-19-2015 |
