Problems solved by technology

[0006] Disadvantageously, prior art separators often allow a significant amount of fiber to remain mixed in the separated impurities, thus making it difficult to determine the total impurities content of a raw fiber sample
Also, the separator described above takes up a lot of space

Embodiment Construction

[0037] Referring now to the figures, various embodiments of a trash separation device 100 operable to separate trash particles 104 from fibers 106 in a fiber sample 102 are described. Fiber sample 102 can take a variety of forms. In one embodiment, fiber sample 102 is cotton, but in other embodiments, fiber sample 102 is formed from other natural or man-made fibers, or combinations thereof. Fiber sample 102 includes both individual fibers 106 and foreign particles 104 .

[0038] exist figure 1 In the illustrated embodiment, the fiber sample 102 is supplied to the foreign material separation device 100 by supplying it between a supply roller 108 and a supply surface or plate 110 . supply roller 108 along (e.g. figure 1 shown) in the first direction from approximately one revolution per minute (0.017s -1 ) to about four revolutions per minute (0.067s -1 ) rotates at a speed such that the fiber sample 102 is drawn between the supply roller 108 and the supply surface 110. In...

Abstract

A separation apparatus (100) for processing a fiber sample (102) that includes both fibers (106) and trash (104) is provided. The separation apparatus comprises a separation cylinder (112) and a collection surface (126) for receiving the trash (104) from the separation cylinder (112). The counter-flow air (122) moves in a separation region between the separation cylinder (112) and the collection surface (126), in a direction that is substantially perpendicular to and towards the underside surface of the separation cylinder (112). The counter-flow air (122) has at each position within the separation region an air-flow velocity sufficient for the counter-flow air (122) to blow the fibers (106) that are not originally retained by the protrusions (114) up toward the separation cylinder (112), and yet insufficient to prevent gravity from pulling the trash (104) downward through the counter-flow air (122).

Description

technical field [0001] The invention relates to the field of fiber quality measurement. More specifically, the present invention relates to the removal of non-fibrous matter (eg, foreign matter) from fibers (eg, cotton). Background of the invention [0002] Various properties of natural and non-man-made fibers are often evaluated in order to rank fiber samples. These properties include many, such as fiber length, strength, color, moisture content, crimp, fineness, and non-fiber content. For example, measuring the properties of cotton fiber in order to provide a quality grade for the cotton is an important step in determining the value of the fiber. [0003] Natural fibers such as cotton can be contaminated with non-primary fiber materials commonly referred to as trash. The foreign matter may be, for example, husks, seeds, twigs, leaves, dust, or stones. Measuring the non-fiber content of a fiber sample is accomplished by separating as much as possible of the fibers in th...
