DETAILED DESCRIPTION

[0040] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.

[0041] Each of the appended claims defines a separate invention, which for infringement purposes is recognized as including equivalents to the various elements or limitations specified in the claims. Depending on the context, all references below to the “invention” may in some cases refer to certain specific embodiments only. In other cases it will be recognized that references to the “invention” will refer to subject matter recited in one or more, but not necessarily all, of the claims.

[0042] Various terms are used herein. To the extent a term used in a claim is not defined, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

[0043] Embodiments explained herein relate to opening of tuffs or lumps of fibre materials, such as cotton or other man-made fibre materials, in blow room of spinning facilities. fibre materials are received in the spinning facilities in highly compressed state in form of bales. When the material is removed from the bales, such as by using bale opening machines, they come out as lumps and tuffs of the material, which are unsuitable for spinning operation. Besides, the material may also contain foreign materials, such as seeds, leaves, dust etc, which need to be separated before feeding the fibre material to spinning machines.

[0044] Therefore, the lumps/tuffs of the material are subjected to a series of operations to loosen the lumps/tuffs so that the foreign material get separated, and the fibre material is ready for spinning.

[0045] FIG. 1 illustrates a schematic diagram showing a typical arrangement used for loosening the lumps/tuffs of fibre material and separating foreign material there from. As shown, the conventional machines and methods for loosening the lumps/tuffs of fibre material is based on spiked rollers, such as roller 102 that loosens the fibre material by pulling/beating the tuffs 104 fed to the spikes of the roller 102. As the tuffs 104 are loosened, foreign material 106 gets separated and falls down, as shown. The loosened fibre material 108 is carried away by suction using compressed air 110.

[0046] Conventional machines and methods, such as shown at FIG. 1, cause a considerable amount of long and good fibbers to break leading to loss in terms of quality of material. Besides, a considerable number of unopened or partially opened lumps pass through along with the opened material, due to which a considerable amount of foreign matter remains in the end product. Since it is not possible to eliminate the foreign matter hidden inside fibre clusters, these unopened lumps/tuffs are removed resulting in loss of good length fibres as waste.

[0047] Embodiments of the present disclosure provide an apparatus and method for opening of the fibre material that overcome drawbacks of conventional method using spiked rollers and/or mechanical beaters. In an aspect, the disclosed method and apparatus implementing the proposed method use bursts of pressurized gaseous fluid, replacing the spiked rollers and/or mechanical beaters, which results in reduced damage or breakage of the fibres, reduce wastage of good fibre, and remove foreign matter more efficiently.

[0048] Referring to FIGS. 2A and 2B, which illustrate exemplary schematic representation, with help of side and top views respectively, of the proposed apparatus for opening lumps and tuffs of fibre material, the disclosed apparatus 200 comprises: at least one chamber 202 with an opening 204 for feeding the fibre material, and at least one nozzle 206 located adjacent to the opening 204 such that a controlled jet of the pressurized gaseous fluid from the at least one nozzle 206 is directed at the lumps 210 of fibre material. The controlled jets of the pressurized gaseous fluid upon hitting the lumps 210 causes the lumps 210 to open, resulting in smaller and more opened tufts of fibre.

[0049] In an aspect, the loosened tufts may be carried away to the next station by a suction or any other device. (not shown here).

[0050] In an embodiment, the gaseous fluid used may be air, which is easily available and cheap to compress. Specifically, equipment to compress air is easily available, and is generally part of blow room facilities, such as for bale opening machine. Thus, the source of the pressurized gaseous fluid may be an external source such as compressed air source of the blow room facilities, or may be inbuilt with the apparatus 200. In an alternate embodiment, it may be a combination of external source and an inbuilt source.

[0051] In an embodiment, the pressurized gaseous fluid can be a mixture of air and a gas.

[0052] In an aspect, the fibre material opened by the proposed apparatus 200 may be any, or a combination of a natural fibre and a manmade fibre.

[0053] In an aspect, the controlled jets of the pressurized gaseous fluid may be bursts of short durations, and the bursts of short duration may be obtained by a control mechanism 208 provided in passage for the gaseous fluid as shown.

[0054] In an aspect, the at least one nozzle may comprise a plurality of nozzles 206 arranged in one or more rows of nozzles, and may be configured such that more than one jets are directed to the lumps/tuffs 210 of fibres from single or multiple directions, simultaneously or in a sequential manner.

[0055] In an embodiment, the nozzles 206 may be fixed or move to direct the jets of air in horizontal plane, or vertical plane, or both horizontal and vertical planes to direct the jets in single or multiple directions, simultaneously or in a sequential manner.

[0056] In an aspect, the jets of air may interact with the tuffs/lumps of fibre material by directly hitting and penetrating the lumps thereby spreading the fibre material to a larger space to open the lump, or may interact by pulling the fibres from the lumps on account of pulling action of the pressurized air flowing over the lump. In either case, action of burst of air jet results in better opening of fibre material and spreading it with reduced damage or breakage of the fibres. In another aspect, separation of fibre material results in loosening of any foreign material trapped by the fibres, leading to cleaning of the fibre material.

[0057] As can be seen, the proposed apparatus is characterized by absence of mechanical beating of the lumps of fibre material for opening the lumps, and therefore, minimizes breakage of fibres.

[0058] In an aspect, the at least one chamber 202 may be shaped to allow spreading of the opened fibre material to a larger volume. As shown in FIG. 2B, the chamber 202 may be of divergent shape to provide more space to the loosened fibre material.

[0059] An aspect of the present disclosure relates to a method for opening lumps and tuffs of a fibre material received from a bale opening machine. As shown at FIG. 3, the proposed method 300 at step 302 involves feeding the lumps of fibre material, such as lumps of fibre material 210 shown in FIGS. 2A and 2B, through an opening such as opening 204, shown in FIG. 2A. Step 304 of the method 300 may be to direct a controlled jet of a pressurized gaseous fluid from at least one nozzle, such as nozzle 206 shown in FIGS. 2A and 2B, at the lumps of fibre material 210 fed through the opening 204. In an aspect, the controlled jet of the pressurized gaseous fluid upon hitting the lumps 210 causes the lumps 210 to open.

[0060] In an aspect, the proposed method further comprises the step 306 of controlling the jets of the pressurized gaseous fluid to create bursts of short durations. The bursts of short duration may be generated using by a control mechanism, such as control mechanism 208 shown at FIGS. 1A and 1B, provided in passage for the gaseous fluid as shown.

[0061] In an embodiment, there may be a plurality of nozzles 206 arranged in one or more rows of nozzles, and may be configured such that more than one jets are directed to the lumps/tuffs 210 of fibres from single or multiple directions, simultaneously or in a sequential manner.

[0062] In an embodiment, the method may comprise step of moving nozzles 206 to direct the jets of pressurized gaseous fluid in horizontal plane, or vertical plane, or both horizontal and vertical planes, to direct the jets in single or multiple directions, simultaneous or in a sequential manner.

[0063] Thus, the present disclosure provides an apparatus and method for opening tuffs/lumps of fibre material using compressed gaseous fluid, doing away with spiked rollers and/or mechanical beaters, overcoming drawbacks of the conventional methods and machines. The proposed method and the apparatus implementing the proposed method reduce wastage of good fibre, prevent breakage of fibre and remove foreign matter more efficiently.

[0064] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
