Abstract
Description
- The present disclosure relates to the field of textile machinery. In particular, the present disclosure relates to a fibre material opening apparatus used in blow room of a spinning facility and method thereof.
- Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention or that any publication specifically or implicitly referenced is prior art.
- Machines used in blow rooms of spinning facilities are well known in the art. When bales of fibre material, manmade or artificial, arrive at a spinning mill, these are subjected to various operations in the blow room to make the material suitable for spinning. As a general rule, operations in a blow room comprise: opening the bale by extracting lumps of densely packed fibre, further opening of lumps of fibre material to smaller tufts, mixing or blending the materials of different types or grades, cleaning of the fibre material, dust removal and uniformly feeding the material to carding machines.
- Blow room installations consist of a sequence of different machines to carry out the above mentioned operations. Typically, each of the machines consist either spike rollers of varying sizes, or various types of mechanical beaters. The natural or manmade fibre material received in highly pressed form, i.e. in bales, is passed through several stages where it is opened into smaller and smaller lumps in a gradual sequence. During this process foreign matter loosened from the material gets separated from the fibre. Since lump/tuft size becomes smaller and smaller with each succeeding stage, the required intensities of processing necessitates different machine configurations for different stages.
- However, treating fibre material with mechanical components like spike rollers or beaters, as in conventional machines, causes a considerable amount of long and good fibbers to break leading to loss in terms of quality of material. Besides, the conventional process also suffers from other disadvantages. For example, 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, they need to be removed resulting in loss of good length fibres as waste with the clusters. If a larger number of beating points were to be used for opening all the clusters, the increased processing causes increased fibre breakage and wastage. Therefore, normally, between three to four beating points are considered to be the boundaries of the most typical setups.
- Therefore, there is a requirement of an improved method and apparatus for opening of fibre material in blow rooms as an alternative to conventional method and apparatus that use spiked rollers or beaters.

As shown, the conventional machines and methods for loosening the lumps/tuffs of fibre material is based on spiked rollers, such asroller 102 that loosens the fibre material by pulling/beating thetuffs 104 fed to the spikes of theroller 102. As thetuffs 104 are loosened,foreign material 106 gets separated and falls down, as shown. The loosenedfibre material 108 is carried away by suction usingcompressed air 110. - 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. - 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.
- 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 disclosedapparatus 200 comprises: at least onechamber 202 with anopening 204 for feeding the fibre material, and at least onenozzle 206 located adjacent to theopening 204 such that a controlled jet of the pressurized gaseous fluid from the at least onenozzle 206 is directed at thelumps 210 of fibre material. The controlled jets of the pressurized gaseous fluid upon hitting thelumps 210 causes thelumps 210 to open, resulting in smaller and more opened tufts of fibre. - In an aspect, the loosened tufts may be carried away to the next station by a suction or any other device. (not shown here).
- 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. - In an embodiment, the pressurized gaseous fluid can be a mixture of air and a gas.
- 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. - 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. - 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. - 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. - 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.
- 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.
- 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 inFIG. 2B , thechamber 202 may be of divergent shape to provide more space to the loosened fibre material. - 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 proposedmethod 300 atstep 302 involves feeding the lumps of fibre material, such as lumps offibre material 210 shown inFIGS. 2A and 2B , through an opening such asopening 204, shown inFIG. 2A . Step 304 of themethod 300 may be to direct a controlled jet of a pressurized gaseous fluid from at least one nozzle, such asnozzle 206 shown inFIGS. 2A and 2B , at the lumps offibre material 210 fed through theopening 204. In an aspect, the controlled jet of the pressurized gaseous fluid upon hitting thelumps 210 causes thelumps 210 to open. - 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 ascontrol mechanism 208 shown atFIGS. 1A and 1B , provided in passage for the gaseous fluid as shown. - 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. - 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. - 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.
