    Abstract: A mounting bracket assembly for connecting a single rotary vibrator to a vibratory feeding device that includes an elastomer spacer member retained and sandwiched between a base plate and a vibrator mounting plate. The mounting plate assembly converts sinusoidal forces exerted by the rotary vibrator to predominantly linear impelling pulses that are in a direction that is perpendicular to a first surface of the base plate. The base plate may be attached to the vibratory feeding device directly or by an adjustable pivot assembly. The direction of movement of items carried on a surface of the vibratory feeding device is directly related to the direction of rotation of the rotary vibrator. The mounting bracket assembly may also include at least one isolation member for minimizing contact of the vibrator mounting plate and retaining members used therewith.

  • Patent number: 6298978
    Abstract: 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.

  • Patent number: 6279731
    Abstract: A conveyor tray is yieldably mounted on a table base and during table operation conveys articles therealong by vibratory motion. A base supports an electric motor for driving a power output shaft journalled on the base. Eccentrics mounted on the power output shaft impart orbital motion to bearing housings each mounted on a flexible connector plate. The upper ends of the connector plates are coupled to the table tray and impart arcuate motion to the tray. The connector plates are of fiberglass reinforced material with each plate supporting a bearing housing with an eccentric. Plates in place on each connector plate are detachably mounted to vary vibratory tray travel.

  • Publication number: 20010015314
    Abstract: An oscillatory drive unit for use in an oscillating system to be oscillated substantially at the resonance point of the oscillating system, wherein the oscillating system includes a mass to be oscillated and a countermass to which the mass is connected by resilient coupling members. The oscillatory drive unit includes a piston-cylinder-component that is operatively connected to the mass and the countermass. The piston-cylinder-component includes a cylinder chamber and a piston. The piston is arranged for reciprocal movement between a first end position and a second end position. Gas is introduced under pressure into the cylinder chamber within an energizing range of piston positions defined by a first energizing position and a second energizing position of the piston, and gas is vented from the chamber within a venting range of piston positions defined by a first venting position and a second venting position of the piston.

  • Patent number: 6145652
    Abstract: A vibrating conveying system having a plurality of rotating shafts and associated eccentric weights uses a sliding eccentric weight or weights mounted on one or more driving shafts to reverse the movement of the articles carried by the conveyor. The sliding weights move between first and second spaced positions relative to the driving shaft when the rotation of the driving shaft is reversed and are latched into place once in the selected positions preventing further movement while the apparatus is operating.

  • Patent number: 6112883
    Abstract: In order to provide the capability of distributing a material that is conveyed, a vibratory distribution conveyor includes a deck having a distribution edge. The distribution edge extends between an inlet end and an end remote therefrom and the deck is subjected to vibratory motion to cause material to be conveyed from the inlet end toward the end remote therefrom. With this arrangement, the declination of the deck is controlled about a longitudinal axis to control the distribution characteristics of the conveyor.
