Description
The invention relates to a weft yarn braking device for storage yarn feeders (accumulator feeders).
As is known, a typical stored yarn feeder may comprise a drum supporting a reserve of yarn (a reserve of yarn) wound thereon, suitable for being unwound on demand by a downstream typical textile machine. Before entering the textile machine, the yarn unwound from the reel passes through a weft braking device which controls the mechanical tension of the yarn.
The weft braking device may comprise a thin-walled, axially symmetric concave body-usually a hollow frustum-shaped body-which is pushed against the delivery edge of the drum by elastic means.
The inner surface of the frustum-shaped body may be covered, in the annular region where it abuts against the drum, by a wear-resistant sheet (wear-resistant laminate) which conventionally has a frustum-shaped annular profile having the same apex angle as the frustum-shaped body.
The yarn unwinding from the feeder slides while being pressed between the delivery edge of the reel and the wear-resistant sheet, in so doing being subjected to a braking action caused by friction.
In EP 0957058, a wear resistant sheet is secured to a hollow frustum-shaped body by double-sided adhesive tape.
Such a solution has the advantage of being very simple to implement, but it also has the disadvantage that the oil released by some of the yarns during the feeding of the yarns may easily cause the double-sided adhesive tape to become detached.
US 6322016 shows some alternative solutions for fixing wear resistant lamellae to a frustum shaped body. In particular, in one of these solutions, the outer edge of the wear-resistant lamellae is clamped by a projection having a U-shaped profile, which is cut directly into the frustum-shaped body.
A disadvantage of such a solution is that, since the protrusion protrudes towards the inside of the wear-resistant sheet, it interferes with the unwinding of the yarn, thus impairing the correct feeding.
Furthermore, the wear resistant lamellae may become slightly deformed in the vicinity of the area clamped by the protrusions. Such local deformations may impair the uniformity of the contact between the wear-resistant foil and the reel and, therefore, the fluidity of the braking action.
Furthermore, the rotation of the wear resistant lamellae relative to the frustum-shaped body is not stopped with certainty, but is only prevented by friction between the materials of the two elements. As a result, particularly in oily environments, sliding may occur between the wear-resistant lamellae and the frustum-shaped body over time, which may impair the accuracy of the braking action.
Furthermore, with this solution, the mounting of the wear-resistant lamellae in the frustum-shaped body is not simple, since the projections need to be lifted one after the other when the wear-resistant lamellae are inserted one at a time, and furthermore there is a risk that the wear-resistant lamellae may be permanently deformed during operation.
It is therefore an object of the present invention to provide a weft braking device for a stored yarn feeder, in which the fixation of the wear resistant sheet to the concave body is stable even in oily environments, does not disturb the unwound yarn, does not affect the uniformity of the braking action, and allows a quick and simple assembly/disassembly of the two elements.
The above objects and other objects, which will become more apparent from the following description, are achieved by a weft braking device having the features set forth in appended claim 1, while the appended dependent claims define other features of the invention.

FIG. 7 is a view similar to FIG. 6, showing a first alternative embodiment of the invention;
fig. 8 is a view similar to fig. 6, showing a second alternative embodiment of the invention.
Referring to the drawings, a typical stored yarn feeder 10 may include a spool 12 supporting a yarn Y wound thereon that is adapted to be unwound on demand by a downstream typical textile machine M (shown only schematically in fig. 1). Before entering the textile machine M, the yarn Y unwound from the reel 12 passes through a weft braking device 14, which controls its mechanical tension, and a yarn guide bush 15.
The weft braking device 14 comprises an axially symmetrical concave body 16, which concave body 16 has its inner surface pushed against the delivery edge 12a of the drum 12 by, for example, elastic means 18 (which are only schematically shown in fig. 1).
Referring now in particular to fig. 2-6, the inner surface S of the concave body 16 is covered, in the annular region where it abuts against the mandrel 12, by a wear-resistant sheet 20, which wear-resistant sheet 20 has a concave annular profile defined between an inner annular edge 20a and an outer annular edge 20 b.
According to the invention, in order to fix the wear-resistant lamellae 20 to the concave body 16, the latter is provided with a series of slits 22 arranged along its circumference, while the wear-resistant lamellae 20 have a series of fins 24, the series of fins 24 projecting from the outer annular edge 20b of the wear-resistant lamellae 20 and being aligned with the slits 22 so as to be inserted therein; the wear resistant lamellae 20 are made of a flexible material having a thickness such that the wear resistant lamellae 20 can initially be applied to a concave body 16 having an opposite concavity with respect to the wear resistant lamellae 20 by inserting the fins 24 into the slits 22 (as shown in fig. 3 and 4) and then be turned inside out so as to have a concavity matching the concave body 16 (as shown in fig. 5 and 6).
Advantageously, when the wear tab 20 is turned inside out, its inner annular edge 20a comes into contact with the inner surface of the concave body 16, while an annular gap G is defined between the outer annular edge 20b of the wear tab 20 and the inner surface of the concave body 16, the purpose of which will be made clear below.
In the embodiment described herein by way of example, the wear-resistant sheet 20 has a substantially frustum-shaped profile, and the inner annular surface S of the concave body 16 covered by the wear-resistant sheet 20 is also substantially frustum-shaped.
Thus, with particular reference to fig. 6, in order to define the above-mentioned annular gap G, the wear-resistant lamellae 20 have a top angle α which is slightly smaller than the top angle β of the inner annular surface S. In particular, the difference between the top angle β of the concave body 16 and the top angle α of the wear-resistant lamellae 20 is advantageously comprised between 1 ° and 3 °, preferably 2 °.
The wear resistant lamellae 20 are preferably made of a sheet of metal material whose thickness is comprised between 0.05mm and 0.2mm, more preferably 0.1 mm.
Advantageously, chromium-plated copper beryllium alloy sheets (sheet of chromium-plated copper-berylium) may be used. However, other metallic materials may be suitable for this purpose, such as steel, aluminum and other metallic materials, all of which are most preferably chrome plated.
In the embodiment shown in fig. 1-6, the concave body 16 is a thin-walled element, preferably made in one piece, having an innermost frustum-shaped portion 16a and an outermost frustum-shaped portion 16b interconnected by an intermediate cylindrical portion 16c, on which intermediate cylindrical portion 16c the slit 22 is provided.
The slit 22 advantageously has a thin elongated profile.
The fins 24 have a generally rectangular profile with rounded corners to facilitate insertion into the slots 22.
Advantageously, the fins 24 extend completely along directrices (directrices) of the contour of the frustum shape of the wear-resistant lamellae 20.
In this embodiment, there are twelve slits 22 and twelve fins 24 equally angularly spaced about the axis of the concave body 16 and the wear resistant sheet 20.
In use, as previously mentioned, the weft brake device 14 is assembled by simply inserting the fins 24 of the wear resistant sheet 20 into the slits 22 of the concave body 16, wherein at this stage the concave side of the wear resistant sheet 20 faces the concave side of the concave body 16 (fig. 3 and 4). Thereafter, by manually pressing the inner annular edge 20a of the wear-resistant sheet 20, the concavity of the wear-resistant sheet 20 is turned over as indicated by the arrow F in fig. 4 (fig. 5 and 6). At this time, the inner annular edge 20a of the wear resistant sheet 20 comes into contact with the inner surface of the innermost frustum-shaped portion 16a of the concave body 16 (fig. 6).
During the yarn feeding, as illustrated in fig. 1, the yarn Y slides while being pressed between the conveying edge 12a of the drum 12 and the wear-resistant sheet 20, and in so doing, is subjected to a braking action caused by friction.
The engagement of the fins 24 in the slits 22 definitely prevents the rotation of the wear-resistant lamellae 20 with respect to the concave body 16 and provides a stable and permanent fixation even in the presence of oil in the yarn.
Another advantage of the system according to the invention is that, according to the set aim, the unwinding of the yarn Y from the reel 12 is not disturbed due to the protrusion of the fins 24 outside the hollow body 16.
Furthermore, anchoring the wear resistant lamellae 20 to the concave body 16 does not lead to deformations in the wear resistant lamellae 20 and thus does not impair the uniformity of the braking action in any way.
Also, it is known that during yarn feeding, yarn Y may release process dust due to friction with the drum 12 and wear resistant sheet 20. This dust will act in some manner between the wear resistant sheet 20 and the concave body 16. However, according to an important characteristic of the invention, the different conicity of the wear-resistant lamellae 20 with respect to the concave body 16 makes it possible to prevent dust pockets (pockets) from forming in the lower region of the weft braking device 10, which could impair the uniformity of the braking action.
As will be appreciated by those skilled in the art, any dust generated during the yarn feed process is discharged through the annular gap G defined between the outer annular edge 20b of the wear resistant sheet 20 and the inner surface of the concave body 16.
Fig. 7 shows an alternative embodiment of the invention, which differs from the previous embodiment in that the concave body 116 has a continuous frustum-shaped profile, the slits 122 are arranged in the circumference of such frustum-shaped profile, and the fins 124 have a curved profile.
In more detail, the fin 124 has:
an innermost portion 124a, which innermost portion 124a extends along the directrix of the contour of the frustum shape of the wear-resistant sheet 120 when the wear-resistant sheet 120 is detached from the concave body 116; when the wear tab 120 is inserted into the concave body 116 and inverted inside-out, the innermost portion 124a flexes due to engagement with the corresponding slit 122, an
An outermost portion 124b, which is stably curved so as to rest against the outer surface of the concave body 116 when the wear-resistant lamellae 120 inserted into the concave body 116 are turned inside out.
Fig. 8 shows a further embodiment of the invention in which the concave body 216 has a continuous frustum-shaped profile, and the slits 222 are provided on the circumference of such frustum-shaped profile, just as in the previous embodiments. However, in this embodiment, the fins 224 extend along the directrix of the contour of the frustum shape of the wear resistant sheet 220, extending completely continuously with the surface of the wear resistant sheet 220. Thus, when the wear tab 220 is inserted into the concave body 216 and turned inside out, the fin 224 is bent to pass through the slit 222 and have the ends of the fin 224 protruding from the outer surface of the concave body 216.
Having described some preferred embodiments of the invention, it is apparent that modifications and variations are possible to those skilled in the art, within the scope of the appended claims.
For example, the number of slots and fins may be increased or decreased as desired.
Further, the contour of the concave body and/or the wear resistant sheet may be different than illustrated. For example, the elements may be slightly arched or hollow, rather than having a profile that is a perfect frustum shape.
Furthermore, although in the embodiments described herein the concave body is pushed against the delivery edge of the roll by separate elastic means, in other cases the elasticity of the material of the concave body may be utilised.
It should also be noted that the material of the wear resistant lamellae may differ from what has been indicated. In particular, although the use of metallic materials should be understood as being preferred, the possibility is not excluded that materials of different nature (in particular synthetic materials) may be suitable for this purpose.
