Filed:

Mar 17, 1997

Appl. No.:

08/819234

Inventors:

Paul I. Sleppy - Penn Run PA
Harold E. Patterson - Indiana PA

Assignee:

FMC Technologies, Inc. - Chicago IL

International Classification:

B65G 2716

US Classification:

198766, 1987521, 4145257

Abstract:

A base excited vibratory trough conveyor includes a trough mounted on leaf springs to a base which is excited by a linear vibratory drive. The vibratory drive produces a linear force which is oriented to be perpendicular to the springs, and the linear force is adjusted to equal the reaction force of the springs on the base during the desired stroke. Such balancing results in no stroke or movement of the base. A more lightweight base can thus be used without requiring that the base center of gravity be aligned along the center of gravity of the conveyor and the trough, or that the base be excessively heavy.

Appl. No.:

10/007843

Inventors:

Harold E. Patterson - Indiana PA

Assignee:

FMC Technologies, Inc. - Chicago IL

International Classification:

B65G 2700

US Classification:

198771, 198760, 198766, 198770

Abstract:

A vibratory conveying device comprise an elongated trough for transporting materials, and a base underlying the trough. A plurality of elongated leaf springs support the trough on the base, with a vibratory drive system operatively connected to the base for effecting vibratory movement of the trough. Economical manufacture and efficient maintenance are facilitated by configuring the base so that it comprises a pair of sheet-like base side members, with a laterally extending drive support member extending therebetween. In the preferred form, the drive support member is detachably connected to the base side members with suitable mechanical fasteners. In turn, a pair of rotary vibratory drives of the drive system are removably mounted on respective opposite sides of the drive support member by a plurality of threaded mechanical fasteners.

Assignee:

FMC Technologies, Inc. - Houston TX

International Classification:

B65G 25/04

US Classification:

1987508, 198764

Abstract:

A differential motion conveyor () for conveying products along an elongated trough structure () supported for reciprocal movement relative to a counterweight base structure () of a weight significantly greater than the weight of the trough structure. A rotational actuator () moving in a singular direction reciprocates the trough structure lengthwise relative and counterweighed base structure at a substantially continually varying velocity of the actuator to achieve a desired differential acceleration rate of the trough structure between the two opposing directions of longitudinal movement of the trough structure.

Assignee:

PPM Technologies, Inc. - Newberg OR

International Classification:

B65G 19/28

US Classification:

1987354, 1988604

Abstract:

The present disclosure provides a slide gate for use in conveyor systems that include permanent magnets to hold slide gate components in place relative to a conveyor trough , while allowing the slide gate to slide between open and closed positions relative to an opening or cutout formed in the conveyor floor. The slide gate is controllably opened and closed by an actuator system and can be magnetically attached to the actuator system such that the slide gate is attached to the conveyor system entirely through magnetic force. Magnetic attachment of the slide gate provides improved performance, ease of cleaning, and safety compared to known slide gate systems.

International Classification:

B65G 2700

US Classification:

1987521

Abstract:

A spring support bracket for supporting a sheet metal trough intermittently on leaf springs provides an L-shaped bracket for a welding connection to a side wall and bottom wall of the sheet metal trough and a spring block extending outwardly from the vertical member of the L-shaped bracket and tilted to the vertical rearwardly of the trough. The spring block includes an aperture for receiving a fastener for connecting a leaf spring thereto so that the trough may be supported by a plurality of leaf springs arranged intermittently along the length of the trough and on opposite lateral sides of the troughs.
