摘要： A method of controlling an object levitating apparatus is disclosed. The levitating apparatus levitates an object on a plurality of vibrating bodies with air pressure generated from sound waves produced by the vibrating bodies. Each vibrating body is vibrated by a corresponding vibrating apparatus. Each vibrating apparatus has an oscillator and a transducer. The transducer is actuated by the oscillator to vibrate the corresponding vibrating body. The method includes determining impedance of each transducer, and controlling each oscillator in accordance with the determined impedance to restrict displacement of the levitated object.

摘要： A vibratory conveyor capable of fluidizing particulate material is capable of separate control of direction, velocity and fluidization of material. The material is placed on a conveyor and vibrated by separate vertical and horizontal components of vibration. The frequency of both components is synchronized over an operating range. Various independent changes in amplitudes can affect the degree of fluidization and flow direction for any particular frequency. For any combination of amplitudes, changes in frequency affect fluidization and velocity. The present invention is adaptable for a range of applications that include drying wood wafers, hog fuel or other organic particulate, warming wood chips, scrubbing flue gas, filtering acting as a reactor and as a gas processor.

摘要： A differential impulse conveyor 10, 80, 90, 100 includes a tray 12 which is driven in a forward direction at a slow speed and a backward direction at a higher speed to slide goods with respect to the tray and thereby move goods along the tray. The drive motor 26, 27 powers the tray in the forward and backward directions through a drive shaft 40 and a tray crank 66, 106 interconnecting the drive shaft and the tray. Controller 84 is provided for varying the rotational speed of the motor shaft, thereby avoiding mechanical knock in the drive system. In another embodiment, a pair of counterweights 52, 62 are provided on opposing sides of the drive shaft 40, with respective counterweight cranks 46, 56 initiating forward movement of each counterweight at a preselected offset angular position with respect to forward movement of the tray.

摘要： A bidirectional vibratory feeder for transporting objects in a curved path has a trough assembly including an elongated, generally horizontal bed defining the curved path, and a center of gravity. Resilient isolators are connected to the trough assembly and adapted to isolate the trough assembly from underlying terrain. An exciter mass assembly includes an exciter frame and a vibration generator coupled to the exciter frame for generating vibratory forces, the exciter mass assembly having a center of gravity. At least one horizontally disposed resilient coupling is connected between the exciter mass assembly and the trough assembly, and at least one vertically disposed link is connected between the exciter mass assembly and the trough assembly. The vibratory forces generated by the vibration generator include a vertical component directed along a substantially vertical path that passes through a combined center of gravity of the trough assembly and the exciter mass assembly that is transferred by the at least one vertically disposed link to cause each point on the trough assembly to translate vertically upward. The vibratory forces also include a horizontal component that is transferred by the at least one horizontally disposed resilient coupling to cause each point on the trough assembly to rotate along a path lying on an arc of a circle in a horizontal plane. The vibration generator is operable in at least first and second modes, wherein, in the first mode, the horizontal component of the vibratory forces is directed along a first linear path displaced from the combined center of gravity to advance the objects in a first direction along the curved path and, in the second mode, the horizontal component of the vibratory forces is directed along a second linear path displaced from the combined center of gravity to advance the objects in a second, generally opposite direction along the curved path.

摘要： A plurality of trough displacement characteristics and drive signals for driving a drive unit 26 for a trough 25 are determined in association with each other and the speed of transport of the articles M transported by the trough 25 having one of the trough displacement characteristics is also determined. Accordingly, a plurality of relationships between the transport speed of the articles M and the drive signal of the drive unit 26 can be determined and, based on these relationships and merely by inputting a target speed to be attained by the articles M, the drive signal for the drive unit 26 can easily be selected which enables the speed of transport of the articles M to attain the target speed. Also, since a travel quantity characteristics indicative of a correspondence between the quantity of travel of the articles and the driving time of the trough 25 with respect to each of parameters of the plural coefficients of kinetic friction &mgr; is determined, the quantity of travel of the articles M with respect to the driving time of the trough 25 can be grasped with respect to the plural coefficients of kinetic friction &mgr; taken as a parameter. Based on this, the coefficient of kinetic friction &mgr; between the desired trough 25 and the articles M can easily be obtained from the quantity of travel of the articles measured by actually driving the trough 25 for a predetermined time to transport the article M.

摘要： The present invention relates to a mechanical vibrating drive system for supplying a consistent, elliptical driving force to a conveyor trough. In a preferred embodiment of the invention, the vibrating conveyor has a set of vertical leaf springs connecting the conveyor trough to a vibratory frame, and a set of horizontal leaf springs connecting the vibratory frame to a stationary frame. The leaf springs amplify the motion initiated by a reversible motor, and the net result is a force output from the drive module that produces a uniform elliptical vibratory motion throughout the length of the conveyor trough. By reversing the motor, a symmetric elliptical motion for moving product in the opposite direction is generated without any further adjustments to the leaf springs.

摘要： The present invention relates to a mechanical vibrating drive system for supplying a consistent, elliptical driving force to a conveyor trough. In a preferred embodiment of the invention, the vibrating conveyor has three parallel shafts, the intermediate shaft being located at the center of gravity for the vibrating conveyor, and the shafts are driven such that the outer shafts rotate in one direction while the intermediate shaft rotates in the opposite direction from the outer shafts. Each of the shafts bears essentially equal weight. The net result is a force output from the drive module that produces a uniform elliptical vibratory motion throughout the length of the conveyor trough. By reversing the motor, a symmetric elliptical motion for moving product in the opposite direction is generated without any further adjustments to the weights or shafts.
