US Patent:

7621392, Nov 24, 2009

Filed:

May 29, 2008

Appl. No.:

12/128868

Inventors:

John L. Langsdorf - Bedford TX, US
Gojko Valencic - Colleyville TX, US

Assignee:

Siemens Industry, Inc. - Alpharetta GA

International Classification:

B65G 23/00

US Classification:

198832, 198794, 1988321, 1985021

Abstract:

A carousel according to the invention uses a number of smaller, less expensive drive units at different locations along the carousel path in place of a single larger drive unit of comparable capacity. Closed loop control according to the invention allows individual drives to be de-energized when the power requirements do not demand their usage. When not energized, the drives may be disengaged from the chain, such as by way of a linear actuator as described hereafter. Benefits of such a system include reduced mechanical costs, longer drive life, better redundancy/higher availability, correct drive power, lower energy use, closed loop system monitoring and reduced collateral damage.

Appl. No.:

13/065383

Inventors:

John Langsdorf - Bedford TX, US
Gary Cline - Southlake TX, US

Assignee:

Transnorm System, Inc. - Arlington TX

International Classification:

B23P 11/02

US Classification:

29448, 198839, 1988442

Abstract:

A conveyor belt for use with a merge or diverge conveying apparatus and a method of providing a new conveyor belt to the conveying apparatus. Polymeric loops attached to each end of the conveyor belt attach the ends of the conveyor belt to each other. Visible wear and tear to the nose bar of the merge or diverge conveying apparatus is reduced when compared to prior art conveyor belts for merge or diverge conveyors.

Abstract:

The present invention is an endless carrier for a conveyor. The endless carrier is equipped with a chain including roller bearings for engaging a wall of the conveyor and slats with landing gears for engaging tracks of the conveyor. The endless carrier is particularly useful for a conveyor having one or more curves.
