Embodiment Construction

[0092] The following instructions describe techniques for controlling attachments for bulk material handling systems. In the following description, a great deal of specific detail (e.g., logic tools, opcodes, devices used to specify operands; source partitioning / sharing / duplication tools, types and interrelationships of system components, and logical partitioning / integration choices) is For a more complete understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, control structures, gate level circuits and entire software instruction sequences have not been shown in detail in order to obscure the invention. Those of ordinary skill in the art will be able to implement the appropriate function from this description without undue experimentation.

[0093] The terms "one embodiment," "an embodiment," "example embodiment," etc. in the specification mean...

Abstract

A bulk material handling system includes a bulk material handling apparatus to convey bulk material and a bulk material handling accessory to aid the bulk material handling apparatus in conveying the bulk material. The bulk material handling accessory includes a controller having one or more sensors. The controller generates a control signal to adjust operation of the bulk material handling accessory based upon at least one status signal of the one or more sensors. The controller also generates the control signal in accordance with a status signal to control signal response pattern defined by system parameter values. The system parameters include a minimum value to define a minimum level of the control signal associated with fail-safe operation and a maximum value to define a maximum level of the control signal associated with stable operation the bulk material handling accessory.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 60 / 824103 (filed August 31, 2006) and US Provisional Application No. 60 / 885084 (filed January 16, 2007). Background technique [0003] Bulk material handling units are used for the storage and movement of bulk materials such as grain, sand, gravel, coal, etc. Bulk material handling plants include primary plants as well as secondary or accessory plants. The main devices include conveyors, conveyor transfer points, transfer chutes, material boxes, silos, hoppers, related structures, etc. Attachments include conveyor belt cleaners, air cannons, industrial vibrators, belt tracking devices and more which are used in combination with the main bulk material handling unit. For example, ancillary devices such as air cannons and industrial vibrators are used in combination with primary devices such as transfer points, transfer chutes, bins, bins and hoppers to facilitate and contr...
