Abstract: Energy-harvesting and -storage devices in conveyor belts and methods for molding those devices integrally into modular plastic belt links. Electroactive polymers or piezoelectric fibers co-injected with a base polymer to form belt modules harvest energy from strain or vibrations in the conveyor belt to power belt on-board devices.

Abstract: A conveyor system and method for cascaded accumulation on a series of in-line roller belts. An accumulation system comprises a series of roller belts that can be actuated in contiguous zones to accelerate conveyed articles forward at twice the belt speed. When articles start to accumulate on the accumulation conveyor, the belt rollers are deactuated downstream to upstream zone by zone. Then the belts are stopped as they fill with accumulated articles. The process is repeated in cascade for the upstream roller belts as articles continue to accumulate.

Piezoelectric materials, electro-active polymers, thermoelectric generators, RF receivers, photovoltaic devices, linear induction generators, and inductive transformer coupling are used to harvest energy to power belt on-board devices.

Abstract: A cleanable belt conveyor and a method for making a cleanable belt conveyor having a simplified frame design. The conveyor includes at least one toolbar and one or more auxiliary components mounted to the toolbar using a snap clamp having a protrusion that mates with a channel on the toolbar.

Abstract: Viscoelastic dampers and belt conveyor systems using viscoelastic dampers to attenuate belt vibration and methods for damping belt speed variations. One version of the viscoelastic dampers includes a low-friction carryway element mounted to a viscoelastic pad that is firmly attached to stationary conveyor framework at various locations along the length and width of the conveyor system. Speed fluctuations of the conveyor belt supported on and advancing along the low-friction carryway elements are damped by the viscoelastic dampers. In some versions, magnetic forces are used to clamp the conveyor belt to the dampers to increase the effective damping.

Abstract: Conveying system and method for sensing and controlling the surface temperature of a conveyor transporting articles through a process that incidentally changes the temperature of the conveyor. The conveyor system includes a conveyor such as a transport belt having temperature sensors embedded in the belt at spaced locations along its length. Transmitters embedded in the belt transmit temperature readings made by the sensors to a remote controller. The remote controller controls a temperature modification unit in the belt's conveyor path that restores the temperature of the belt to an optimum range for the processing of the articles. The controller creates a temperature map of at least a portion of the conveyor path.

Abstract: Conveying systems and method for measuring accelerations in a conveyor advancing through process equipment and taking remedial and prophylactic action in response. The conveyor system includes a conveyor with embedded accelerometers making measurements conveyor accelerations. A controller uses the measurements to control the speed of the conveyor to compensate for unwanted accelerations or to damp the unwanted accelerations. The controller can also use the measurements to warn of unwanted accelerations or to predict the failure of associated or nearby equipment so that maintenance can be scheduled and to detect imminent failures and shut down the process.

Abstract: Conveying systems and method for detecting the presence of static electric charge on a conveyor. The conveyor system includes a conveyor with an outer conveying surface. Embedded or external static-electricity sensors make measurements of static electricity on the belt's conveying surface. A controller uses the measurements to control the level of electric charges on the belt by transferring charge to or from the belt.

Abstract: Methods for singulating laterally abutting conveyed articles in a conveyor (60). The method includes separating laterally abutting articles by means of a first conveyor section (62) having in-line rollers (64) or oblique rollers rotating at a first speed in a conveying direction (70) and a second laterally adjacent conveyor section (63) having oblique rollers (65) rotating at a second speed in a direction causing articles atop the oblique rollers (65) in the second section (63) to diverge from articles atop the rollers in the first section. Differing the roller speeds helps the abutting articles to increase their separation in the conveying direction.

Abstract: A separation conveyor using a roller belt whose rollers are already rotating before receiving an article to provide immediate pull-away from an infeed conveyor. The rollers of a roller belt extend through the thickness of the belt and into contact with a bearing surface in a reversing segment of a belt path between the returnway and the carryway of the separation conveyor. The rollers are already rotating on the bearing surface in the reversing segment at the infeed end before they contact articles to avoid delays in pulling articles away from the infeed conveyor and onto the separation conveyor.

Abstract: Conveyors and methods for operating conveyors to accelerate laterally adjacent conveyed articles over different distances. The conveyors provide a conveying surface atop rollers in a conveyor belt. The belt rollers ride on a bearing surface underlying the belt on a carryway. As the belt advances, the rollers riding on the bearing surface rotate in a direction of rotation to accelerate conveyed articles along the belt in the direction of rotation. The bearing surface is shaped so that its length in the direction of belt travel varies across the width of the conveyor.
