FIELD OF INVENTION
The present invention relates to a method and a system for detecting and removal of contaminants in a free falling textile material.

BACKGROUND OF INVENTION
Contamination sorting machine in Blow room or Ginning process is used to detect and eject the contaminants present in the textile material. Usually, the detection module of contamination sorter scans for contamination in a fast moving textile material. The flow of textile material is achieved by means of an external force like suction. The velocity of textile material varies based on the suction, tuft size and production demand of the forward process machinery. Since the velocity is dynamically variable, the efficiency of the contamination detection device varies.

Most of the commercially available Contamination sorters are positioned at the final stage of the Blow room line. These Contamination sorters comprise of detection and ejection system for removal of foreign material from the transportation ducts wherein the material is transported at a variable velocity. Thus the performance of these devices varies. Also due to the transport of textile material at a high speeds, the detection, illumination and ejection systems should be more precise thus the manufacturing cost increases significantly.

To overcome this challenge, the present invention attempts to detect the contaminants in the textile material at a zone where it falls freely without any external forces. The present inventors have surprisingly developed an efficient system and method for contamination detection and removal which ameliorates the aforesaid shortcomings of the prior art.

DETAILED DESCRIPTION OF THE INVENTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary.

Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the scope of the invention as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments.

It should be emphasized that the term “comprises/comprising” when used in this specification is taken to specify the presence of stated features, steps or components but does not preclude the presence or addition of one or more other features, steps, components or groups thereof.

The term “free falling zone” as used herein means a place during the textile manufacturing processing wherein the textile material falls freely without any external forces like suction. The textile material flowing through this free flowing zone is defined as free falling textile material.

The term “Blow room” as used herein means the section where the supplied compressed cotton bale turns into a uniform lap or opened flocks by opening, cleaning, blending or, mixing. It is the first step of spinning. This section consists of a number of different machines used in succession to open and clean the fibres. Blow room is named defining the air flow i.e. the procedure is carried due to the air flow atmosphere. In blow room process usually 40%-70% of trash is removed.

The term “ginning” as used herein means the process by which the fibers are separated from the seeds.

The present invention relates to a method and a system for detecting and removal of contaminants in a textile manufacturing process.

Especially, the contaminant detection and removal module in the present invention is positioned in a place where textile material falls freely. Alternately, the free falling arrangement can be introduced in between any stages of Ginning or Blow room machinery where the contaminant detection and removal module is integrated. Also, the free falling arrangement with contaminant detection and removal module can be independent standalone module without integrating in Ginning or Blowroom process.

Typically, the feed trunk which is a free fall zone in a Blow room opening machine is cuboid in shape wherein the opened textile material from the previous machine falls freely and stacked temporarily. After stacking in the free fall zone before the opening machine, the textile material is fed into the opener slowly for opening and cleaning process.

The present invention comprises a contaminant detection module kept across the free fall zone to detect contaminants. The contaminant detection module can be single or plural. They can be positioned in one line or can be offset and positioned for improving the contamination detection efficiency.

A separate ejection zone is made available in the free fall zone wherein the detected contaminants are ejected.

Reference is now made to Figs 1 to 2 which illustrate an embodiment of the present disclosure.
