Filed:

May 20, 2009

Appl. No.:

12/468937

Inventors:

Scott A. Bailey - Cincinnati OH, US
Brady P. Ballman - Loveland OH, US
Nicholas P. Gardner - Cincinnati OH, US
James G. Potter - Harrison OH, US

Assignee:

Rotex Global, LLC - Cincinnati OH

International Classification:

B07B 1/46

US Classification:

209405, 209408

Abstract:

A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a machine frame and a perforate screen panel mounted for movement relative to the machine frame during a screening operation. The screen panels are pre-tensioned mesh screen material mounted in a peripheral rim for separating various granular and particulate materials. The screen panel is slid into the side of the machine frame in a direction orthogonal to the direction particulate matter moves when the screening machine is operating. The screen panel peripheral rim has a shaped or other cross section adapted to hold a large seal member that provides a positive sealing surface for contact with the machine frame to prevent particulate matter from escaping off of the screen panel during use.

Appl. No.:

11/685811

Inventors:

Brady P. Ballman - Loveland OH, US
Nicholas P. Gardner - Cincinnati OH, US
James G. Potter - Harrison OH, US

Assignee:

ROTEX, INC. - Cincinnati OH

International Classification:

B07B 1/28

US Classification:

209309, 209404

Abstract:

A screening machine includes a vibratory carrier and a vibratory drive operatively coupled to the vibratory carrier for imparting vibratory motion thereto. The screening machine includes a screen assembly selectively coupled to the vibratory carrier so that the vibratory motion is transmitted to the screen assembly. A sealing mechanism including at least one rotary cam having a cam surface and at least one actuator being accessible to a user of said screening machine is coupled to the rotary cam. Actuation of the actuator to rotate the cam urges the screen assembly and the carrier into sealing engagement with a confronting surface of the screening machine. The screening machine further includes at least one stop positioned relative to the sealing mechanism to limit rotational movement of the rotary cam in at least one direction.

Inventors:

- Cincinnati OH, US
Nicholas P. Gardner - Cleves OH, US
Dustin M. MacFarland - Trenton OH, US

Assignee:

Rotex Global, LLC - Cincinnati OH

International Classification:

B07B 1/46

Abstract:

A screen panel has a pre-tensioned screen with a polished metal plate mounted to the top of the frame to eliminate all the exposed surface areas of epoxy which secures the screen to the screen panel frame. The metal plate also provides an edge against which a silicone bead may be seated to provide a much cleaner and finished looking panel which is anticipated to meet the standards set forth by the USDA. Additionally, the spatial positioning of the plate atop the screen material and screen frame allows for a clean and smooth transition across the components and one which may accept a finished bead of silicon or other material for reducing and/or eliminating sites for mold growth or other containments thereby enhancing the ability to clean and sterilize the screen panel for the processing of various materials.
