Abstract
Description
- The present invention relates to an opening machine for separating the fibres from intermingled vegetable impurities in cotton tufts, of the type defined in the preamble to claim 1. The invention also relates to a method of opening cotton tufts and the like.
- Conventional opening machines comprise an upper storage bin or supply chamber into which the cotton tufts to be processed are introduced. At the bottom of the storage bin there is an opening cylinder (with prongs, needles or clothing) which cooperates with cleaning blades to split up the fluffy masses of cotton at least partially into their individual constituent fibres, eliminating the intermingled vegetable impurities (parts of leaves, of capsules, of seeds, earth, etc.) therefrom. In the vicinity of the opening cylinder there are usually suction openings for removing the impurities separated from the fibres and a duct through which the impurity-free fibres are removed.
- An example of this known technology is provided by U.S. Pat. No. 4,858,277.
- In conventional opening machines, the material in tufts usually reaches the opening cylinder in the form of a compact mat. When the material is processed in the compacted condition, the opening cylinder cannot achieve good separation of the fibres from the vegetable impurities, unless a clothing having quite “aggressive” characteristics towards the material to be treated is selected for the opening cylinder. However, a clothing of this type brings about the breakage of a considerable quantity of fibres.
- An object of the present invention is to provide an opening machine which can eliminate the disadvantages of the prior art discussed above. In particular, it is an object of the invention to provide an opening machine which can bring about improved cleaning efficiency, that is, which can achieve better separation of the vegetable impurities from the fibres, without damaging the fibres.
- Another object of the invention is to provide an opening machine which can operate with a shorter working cycle.
- These and other objects and advantages which will be understood further from the following are achieved, according to the invention, by an opening machine having the characteristics defined in claim 1.
- According to a further aspect of the invention, a method comprising the steps defined in
claim 15 is proposed. - A preferred but non-limiting embodiment of an opening machine and of an opening method according to the present invention will now be described with reference to the appended drawing, which is a schematic, vertically-sectioned view of an opening machine according to the invention.
- With reference to the drawing, an opening machine according to the present invention is generally indicated10. The general structure of the opening machine shown in FIG. 1 may be considered generally known; only the elements which are of specific importance and interest for the purposes of the implementation of the invention will therefore be described in detail in the following description. For the construction of the parts and of the elements which are not described in detail, reference may therefore be made to any known opening machine.
- The
opening machine 10 comprises a substantiallyvertical storage bin 11 in the upper portion of which there is anintake device 12 connected to aduct 13 for the supply of cotton tufts from the exterior. - In the lower portion of the opening machine there is a conventional opening cylinder, indicated14, associated with
conventional cleaning blades 15,carding segments 16 andopenings 17 for the suction and removal of the impurities separated from the fibrous portion of the cotton tufts. The fibres, on the other hand, are removed by suction through aduct 18. - An important characteristic of the solution according to the invention is that, in the lower portion of the
bin 11 in which the tufts to be processed are stored, there is a set of three rollers which can perform a preliminary opening operation on the tufts and can supply the tufts to theopening cylinder 14 in a controlled manner and in an at least partially-opened and non-compacted condition. - Two
feed rollers 19 and 20 are arranged substantially side by side in the lower portion of thestorage bin 11 and are rotated in the directions indicated by the arrows in order to withdraw, in a metered manner, the material which is usually in a compacted condition in the base of thestorage bin 11, and to supply this material, in a less dense condition, to apre-opening roller 21. - The
feed roller 19 has projectingperipheral elements 19 a adapted to force the tufts of material to fall into the passage between therollers 19 and 20. - The feed roller20 has an
outer clothing 20 a which serves to restrain the cotton tufts whilst they are located in the narrow passage between therollers 20 and 21 and are subjected to a rubbing action by means ofelements 21 a projecting from the periphery of thepre-opening roller 21. Since thepre-opening roller 21 is rotated at a tangential velocity considerably greater than that of the clothed roller 20 and of thefeed roller 19, it brings about, by means of theouter elements 21 a, a preliminary or at least partial opening of the tufts which are dragged along by theclothing 20 a of the clothed feed roller 20. By way of indication, the feed roller 20 rotates at a tangential velocity of between 1.5 and 4 m/min., whereas the preopeningroller 21 rotates at a tangential velocity of between about 400 and 600 m/min. - Preferably, a passage having a width of between 0.5 and 2 mm, and most preferably of about 1 mm, is defined between the
clothing 20 a of the roller 20 and the ends of theelements 21 a of thepre-opening roller 21. - The tufts, in a partially-opened condition, are thus thrown by the
peripheral elements 21 a of the rotating pre-openingroller 21 into anintermediate supply chamber 22 disposed immediately upstream of theopening cylinder 14 and of afeed roller 24 associated therewith. - It is important to note that the
feed roller 24, which is disposed in the lower opening of theintermediate chamber 22, is rotated at a tangential velocity greater than that of thefeed rollers 19 and 20 so as to prevent accumulation of material in theintermediate chamber 22. In other words, the material coming from thepre-opening roller 21 reaches thefinal feed roller 24 in the form of non-compacted tufts. The speed of rotation of thefinal feed roller 24 is preferably regulated in a manner such as to supply the material to thecylinder 14 with a theoretical delivery rate about 10÷50 times greater, preferably about 30 times greater, than the delivery rate of thefeed rollers 19 and 20, or the quantity withdrawn from the base of thebin 11 thereby per unit of time. - Moreover, since the
peripheral elements 21 a of the preopeningroller 21 can exert a pumping action on the air, towards thechamber 22, the chamber preferably has a grating or perforated plate 23 which allows the air to escape and thus prevents the formation of undesired excessive air pressure inside the chamber. - The individual partially-opened cotton tufts are then passed from the
chamber 22 to theopening cylinder 14 by means of thefinal feed roller 24. Since the cotton tufts reach theopening cylinder 14 in an already partially-opened condition, thecylinder 14 can advantageously have finer or less aggressive clothings in order to process the cotton tufts more effectively and to separate their fibrous cotton fraction from the impurities without damaging or breaking the fibres. - Naturally, the principle of the invention remaining the same, the details of construction and forms of embodiment may be varied widely with respect to those described and illustrated, without thereby departing from the scope of the invention as defined in the appended claims.
