Description
A device for the production of assorted or patterned yarn with the addition of different coloured fibres or of different nature.
The present invention refers to a device to be applied to ring spinning machines for producing assorted or patterned yarns with the addition of different coloured fibres or of different nature.
More precisely, it relates to a device which permits to spin, through the passages of the ring spinning machine, two roves of equal or different properties, dosing in a controlled way the quantities of each fibre and thus mixing them in order to obtain an assorted and patterned yarn wherein the fibres deriving from a base rove are covered with fibres added of different colour or nature.
Nowadays, there are various devices which are based on principles similar to the ones of the present invention, the most recent of which is the object of patent KR-10-0643097.
This patent describes a system, shown in Fig. 1, wherein the drawing field of the spinning machine, normally formed by three shafts and relative pressure rollers are represented by the symbols:
• B (supplying shaft) ,
• M (middle or pre-drawing field shaft) ,
• F (output or drawing shaft) ,
is to be modified with the addition of a fourth shaft indicated with C in the same figure 1, which is used for supplying a second rove .
Each shaft, as said, is provided with a respective pressure roller B' , C , M' , F' and respective belts R and R' are wound around shaft M and around relative roller M' .
Furthermore, the pressure rollers are hollow, as shown in figure 2, so that:
• base rove S is free with respect to added shaft C,
• colour rove T is free with respect to shafts B and M.
In this way, the effective drawing field for base rove S remains the original one between shafts B and F, whereas the drawing field for colour rove T is the new one created between shafts C and F.
The two roves S and T can then be differently drawn opportunely applying two different speeds to shafts C and B, being output F common to both.
By applying intermittent speeds to shaft C, is therefore possible to vary the quantity of fibres of
the colour rove which will be added to the base rove.
These roves treated in this way, are then reunited at the output by a compactor device indicated in the abovementioned figures 1 and 2 with V, to which the thread guide group G follows; together, they permit the formation of a yarn wherein the fibres deriving from colour rove T "cover" the fibres deriving from base rove S, according to the desired criterion.
Let's observe now figure 3, still relative to the device proposed in patent KR-10-0643097, wherein the left part shows the advancement of base rove S, whereas the right one shows the advancement of colour rove T. It is to be noticed that for base rove S the total drawing field is formed by two tracts Dl and D2 , thus respecting the distances which are normally set up on the spinning machines and which must be compatible with the length of the worked fibres, in order to permit an effective control of themselves, as recalled by the elementary spinning principles.
This does not happen, on the other hand, for coloured covering rove T, because it is necessary to eliminate pressure belt R' on cylinder M' on the side of covering rove T (see also Fig. 2) and therefore resulting distance D3 is very long and not anymore
compatible with the length of the fibres.
This makes the quantity and the length of the fibre which derive from the added rove and which must cover the fibres deriving from the base rove not completely controllable.
The above is therefore a strong limit to the functioning of the device proposed in patent KR-IO- 0643097, because it makes the aspect of the yarn thus obtained dependent not only on the speed variations made on cylinder C and on the time intervals within they are made, but also on other casual phenomena which depend on the non control of the fibres, consequence of distance D3 within which the covering rove is drawn.
This implies that the patterned yarn produced according to this principle does not have characteristics surely reproducible over time, making practically impossible the use of this application for an industrial -level production.
The present invention solves the abovementioned issue, proposing a solution which does not require the additional cylinder for supplying the coloured rove and keeps the correct size of the drawing field for both roves (base and covering) , in such a way as to permit the complete control of the fibres which
form the final yarn formed by base fibres, "covered" by fibres of the coloured rove.
For these and other purposes which will be better understood in the following, the invention proposes to realize a device according to claim 1.
Below it is described the functioning principle of the present invention, through the use of other figures which show
in Fig. 4 and 5 respectively a top view and a side view the device according to the invention,
in Fig. 6 a section of the device relative to two successive spindles and
in Fig. 7 a perspective view of the entire system.
The drawing field of the spinning machine remains composed of three cylinders shown in figures 4 and 5 by symbols:
• B (supplying shaft) ,
• M (middle or pre-drawing field shaft) ,
• F (output or drawing shaft) .
Pressure cylinders B' and F' related to shafts B and F are not modified, with respect to the solution shown as prior art, whereas pressure cylinder M' of middle shaft M and relative supporting belt R' are divided, so that the two halves HB and HC can rotate
at speeds different the one from the other.
Middle shaft M is sectioned in various parts as it can be observed in Fig. 6, so that the necessary control is provided to the rollers and conveying belts HB and HC.
In figure 6 it is shown by way of example a section of shaft M relative to two successive spindles :
• M: axis or shaft
• MB: craft integral with shaft M. The external surface of this craft is opportunely treated for dragging lower belt CB and for moving forward the fibres of the base rove
• HB: roller and upper belt of the pre- drawing group which is pressed against craft MB by the pressure arm of the spinning machine
• BR: bearings for craft MC
• MC: craft fixed to bearings BR, the rotation of which is then independent from the rotation of shaft M and of crafts MB
• PT: toothed wheel or pulley integral with craft MC.
Being all sections MB integral with shaft M, shaft M acts as common control among all sections MB and relative supporting belts HB, wherein are drawn
the roves used as base.
Shaft M (with relative sections MB and belts HB) receives the command from the machine and carries out the function proper of the middle shaft, thus concurring to the middle drawing of the fibres which constitute the base of the yarn.
Each section MC is coaxially inserted on shaft M, but does not rotate integral with it, being fixed on bearings or on auto-lubricating bushings BR which make it independent from the shaft itself, which acts in this case as support for said sections.
Furthermore, as highlighted in figure 6, each section MC presents a pulley PT which is controlled by a driving belt which in its turn receives the movement from a driving pulley PM positioned on an additional shaft D, which can be arranged in the most suitable positions in such a way as not to be an obstacle or encumber for the working.
As it can be seen from the preceding illustrations, and in particular from the schema of figure 4, the base rove thus undergoes drawing D1+D2, determined by the speeds of shaft B with respect to sections MB of shaft M, and by the speed of the middle roller and relative supporting belt HB, dragged by sections MB of shaft M with respect to the
output speed of shaft F.
Analogously, the coloured rove will undergo drawing Dl determined by the speed of the middle roller and relative supporting belt HC dragged by sections MC of shaft M, with respect to the output speed of shaft F.
In this way, providing shaft D with appropriate command and independent from the command of shaft M, it is possible to adjust the speed of craft MC dosing the quantity of coloured fibres which have to be inserted in the yarn and, controlling in an intermittent way this shaft, the patterned effects are realize'd, obtained through the insertion of fibres of colour and/or nature different from the fibres used in the base rove.
A fundamental characteristic of the present invention is therefore that the abovementioned drawing fields, because of the particular configuration of the device, comply with the length requirements in such a way as to permit the complete control of the fibres which form the final yarn formed by the base fibres, "covered" by the fibres of the coloured rove .
Therefore, it is possible to create effects which length, frequency and thickness are manageable
by a programmer device, wherein these quantities are manually set up and can be repeated with any desired course. These effects will be correctly carried out on the yarn, being the programmer device synchronized with the produced yarn at the output, through the impulses received by a sensor positioned on shaft F of the spinning machine which detects, practically, the quantity of yarn produced at the output of the spinning machine at each impulse detected by the sensor. For example, at each impulse of the sensor corresponds 1 mm of produced yarn.
The programmer will thus provide for the releasing of the coloured fibres by operating shaft D for the time necessary for producing the effect of the desired length (provided that it is not lower than the length of the fibres which constitute the coloured rove) , where this time is the one necessary for receiving the number of impulses correspondent to the programmed length. For example, if an effect 25 mm-long is desired, the programmer will operate the shaft till 25 impulses will be reached from the beginning of the effect .
Having reached the number of impulses selected, shaft D will be kept still by the same programmer for the time period necessary for producing the yarn
without the coloured effect corresponding to the number of impulses which have been set up by the programmer device .
In this way it is possible to create the coloured effect of any desired length and of length exactly equal to the one set up by the electronic programmer device.
Thanks to the characteristics of this invention, with this programmer device it will be possible to influence also the thickness of the coloured effect, through the insertion of a higher or lower quantity of coloured fibres, still referring to the impulses detected by the sensor positioned on shaft F, where, in this case it is calculated the frequency of the impulses per second, which is equal to the rotation speed of the shaft itself.
Actually, drawing Dl of the coloured rove is determined by the ratio between the tangential speeds of shaft F and of craft MC which determines the advancement of the fibres of the coloured rove.
From the detection of the tangential speed of shaft F, which is proportional to the frequency of the impulses of the sensor positioned on the same shaft F, the electronic programmer device determines the speed which must be given to craft MC, during the
period in which shaft D is operated, in order to apply the desired drawing Dl to the coloured rove.
It is clear that the higher drawing Dl applied, the lower the quantity of the inserted coloured fibres, and the maximum thickness, equal to the one of the coloured rove, is reached if the ratio, that is the drawing, will be equal to the value 1, that is all the fibres of the coloured rove are inserted in the base rove .
In figure n. 7 it is provided, by way of example, an axonometric image of the system which constitutes the present invention of which Fig. 6 is a partial section.
The present invention therefore permits to obtain a patterned yarn formed by a base rove to which are added the effects (of different colour or nature of the fibres) the dimensions of which (length, thickness and frequency) are programmable by an opportune electronic system.
Another possible application of the present invention is to operate shafts B and M, which( supervise according to the present invention the advancement and the formation of the base rove (see figures 4 and 5) , at not constant speed as it happens in the traditional devices commonly known as
"flamers" . In this way it is possible to superimpose and/or add the flaming effects produced on the base rove, the effects obtained with the present invention, in such a way as to obtain a yarn provided with flames of two colours, being the first the one of the base rove and the other the one realized with the coloured rove which covers the base rove, as explained according to the present invention.
The electronic control device, will provide for opportunely synchronizing the two flaming sequences, in order to obtain the desired aspect, giving the desire weight to the two types of flames (base and colour) which are then created on the yarn produced according to the present principle.
According to the invention, compactor device V, shown in figures 4 and 5, can be traditionally an aspirator or a simple fixed stick or rotating around its longitudinal axis which deviates the path of the continuous fibres in such a way as to bring them in correspondence with the output of the coloured ones so that these ones are collected by the continuous yarn.
