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.
Claims11
In a conveyor having a base and a vibratory tray having a range of travel and yeildably mounted on the base and on which articles are conveyed, the improvement comprising,
- a power source on the base,
- an eccentric driven by said power source,
- drive assemblies powered by said eccentric and each including a flexible connector plate having a first end segment attached to a tray, a bearing assembly including a housing about said eccentric said connector plate having a second end segment, mounting means for mounting said housing on the second end segment of the flexible connector plate and including fasteners permitting housing detachment from the connector plate, elongate stiffener means extending in a lengthwise direction along said connector plate to alter flexibility of the connector plate.
In a vibratory conveyor table having a base and a movably supported tray on which articles are conveyed, the improvement comprising,
- a power source,
- an eccentric driven by the power source and having a rotational axis, and
- a drive assembly including a connector plate of elongate shape and of flexible synthetic material having a first end coupled to the tray, a housing in place on said eccentric and carried by a second end of the connector plate, said eccentric at all times vetically offset from said second end of the connector plate and imparting flexure and linear loads to the connector plate.
A drive assembly for a conveyor having a base and a vibratory tray,
- a power source on said base,
- a drive assembly imparting vibratory movement to the tray including a flexible connector plate having a first end segment coupled to the tray, a bearing assembly, fastener means for attaching the bearing assembly to a second end segment of said flexible connector plate, a power output shaft driven by said power source and having an eccentric thereon imparting orbital motion to the bearing assembly and to said second segment of the connector plate, said eccentric having a rotational axis at all times vertically spaced from said second segment of the connector plate.
