Abstract
Description
- The present invention relates to a device for capturing the yarn end of a bobbin, in particular, but not exclusively, the yarn end of a spun whose unraveling is difficult, as, for example, wet flax.
- As known, with bobbins coming from wet flax manual spinning wheels, it is difficult to detach the yarn end from the surface of the bobbin. This is due to the wet spinning cycle, whereby the wet cellulose, of a slimy and sticky consistency, which is released from vegetable fibers such as flax and cotton, once dried, tends to stick the coils one another, and makes the yarn stiff. Once detached, the yarn is difficult to unravel because it remains adherent to the underlying coils, again due to the stuck cellulose.
- Usually the bobbins end with highly inclined binding windings, and finally with a number of binding windings (or "underwinding") at the bottom of the tube.
- In order to prepare the bobbin for the next coiling, it is required to:
- capture the yarn end with conventional separation means, such as a metal leg for detaching the yarn end, a wrinkled pad for separating very tight yarn ends;
- separate the yarn end from the bobbin, unraveling the yarn end with bellows and sucking it with an associated suction pipe;
- unwind the yarn end to such an extent so that it has a length sufficient to be introduced inside the tube; and
- insert the yarn end into the tube by means of suction by means of the plate and the tube.
- To make the feeding of the bobbins following the coiling units faster, it is necessary that
- the bobbin has at most two binding windings;
- the bobbin does not have an underwinding;
- the tube has a top hole with a diameter of at least 12 mm;
- the yarn has a moisture content of at least 7%-9% to make the yarn flexible.
- Special arrangements are also required at the head or yarn end searching station. The yarn end separation station is usually equipped with two legs which are brought into contact with the surface of the bobbin to detach the yarn end. To effectively operate on different types of bobbins, two legs are generally provided for, a metal hook-shaped one that is needed for breaking and separating the yarn end on the cylindrical surface of the bobbin and a pad one in a rubbery material with a rough surface, or a pad one with metal serration, which is needed for separating the underwinding yarn end at the base of the tube, if present. One or more nozzles are also used to lift the detached yarn end upwards, as well as a vertically movable pipe for the suction of the yarn end.
- Generally, a photocell is provided inside the suction pipe for detecting the presence of the yarn, i.e. that the yarn has been captured. A cutting device, mounted in the suction pipe, provides for cutting the yarn after a length thereof has been extracted from the bobbin sufficient to drive it back, by means of suction and/or blowing, inside the tube by means of the top thereof and make it remain stably therein until the moment when it is required that the yarn is fed from the bobbin to a winding machine.
- It is an object of the present invention to effectively capture the yarn end, in particular for spuns of the type discussed in the introduction, to extract a sufficiently long portion thereof from the bobbin so that it may be neatly inserted into the top of the tube so as to proceed with subsequent processes.
- According to the invention, the aforesaid purpose and other advantages are achieved by an apparatus having the features defined in the appended claims.
- In summary, the yarn end is unwound from the bobbin thanks to the fact that the yarn is grasped by a gripping device mounted inside a telescopically movable part of the suction pipe. The gripping device mechanically clasps the yarn detached from the bobbin and pulls it to a certain length. In this way, a yarn portion is forcibly unwound from the bobbin having a length which allows the pipe suction to unwind a further yarn portion. When the unwound yarn has reached the length required to be stably inserted into the tube, the yarn is cut and inserted inside the tube.
- The structural and functional features of a few preferred embodiments of an apparatus according to the invention, but not limited thereto, will now be described. Reference is made to the accompanying drawings, in which:
-
Figures 1-8 are schematic elevation views, partially sectioned, showing a sequence of operating steps in an apparatus according to one embodiment of the invention; -
Figures 9 and 10 respectively are a vertical view in vertical section and a horizontal sectional view showing a mechanical yarn gripping device; and -
Figure 11 is a schematic top view of an alternative embodiment of a mechanical yarn gripping device. - With reference to the drawings, the entirety of an apparatus for the capture of the yarn end P of a yarn F from a bobbin S is indicated with
reference number 10. - The apparatus comprises a
telescopic suction pipe 20 which a bellow-holder group 50 is associated thereto. The bobbin S is supported by aconventional support plate 40. - Some of the elements represented in the Figures are to be considered generally known. Consequently, in the following of the present description, only the elements of specific importance and interest for the purposes of the implementation of the present invention will be described in detail. For the constructional and functional features of the parts and elements not shown in detail, reference may therefore be made to any yarn end search and capturing system of a known type.
- The
telescopic suction pipe 20 comprises an upperstationary pipe 21, connectable to a suction source (not shown), and alower pipe 22 vertically slidable along a lower end portion of thestationary pipe 21. - The
stationary pipe 21 has alower end 23 and is associated with afirst photocell 24 placed at a determined distance d above thelower end 23. Thephotocell 24 is needed for detecting the presence of the yarn end P inside thestationary pipe 21 at the distance d from thelower end 23. - A
yarn cutting device 25, schematically shown, is mounted adjacent to thefirst photocell 24, in this example immediately above thefirst photocell 24. - The
lower pipe 22 has abottom mouth 26 with aninlet surface 27 tapering upwards and towards the center of the pipe. In this example, the taperinginlet surface 27 is a conical surface. - A mechanical
yarn gripping device 28 is arranged in thelower pipe 22, preferably adjacent to thebottom mouth 26. - The
lower pipe 22 may have asecond photocell 29 preferably placed adjacent to thegripping device 28, thereabove. Thesecond photocell 29, optional, may be needed for detecting the presence of the yarn end B P inside thelower pipe 22. - A
linear actuator 30 is arranged to cause thelower pipe 22 to telescopically slide along the upperstationary pipe 21. - The
telescopic suction pipe 20 defines a central and vertical geometric axis x, along which the bobbin S is aligned, below thepipe 20. - The
plate 40 for the support of the bobbin has a centralvertical pin 41, aligned with the axis x, which is inserted into the lower end A of the tube T of the bobbin. Theplate 40 has aninner channel 42 connectable to a lower suction device 34 (Figure 7 ), which is needed to draw by suction the yarn end into the upper end B of the tube. An example of a support and suction plate is given in patent publicationIT 1 270 010 B - The bellow-
holder group 50 may comprise a bellow-holder ring 51 having a plurality ofnozzles 52 distributed about the axis x and facing upwards and towards the central vertical axis to facilitate the separation of the yarn end from the windings of the bobbin. The bellow-holder ring 51 is vertically movable along the axis x by means of alinear actuator 53. An example of a bellow-holder ring may be found in patent publicationJP H07133071 A - Preliminarily, in a first processing station (not shown), the bobbin may be treated in a known manner by one or more yarn end mechanical separation elements, for example by means of slidable elements on the surface of the bobbin in rotation which cause the separation/break of the binding windings, as for example known from patent publication
EP 1 932 793 B1 . A wrinkled pad may also be used for separating the underwinding yarn end. - The bobbin S, mounted on the
support plate 40 thereof, reaches a yarn end capturing and insertion station, where the apparatus 10 (Figure 1 ) is provided. - The bellow-
holder ring 51 is lowered around the bobbin S (Figure 2 ) and thenozzles 52 blow upwards separating the yarn end P which is sucked into thesuction pipe 20. The taperinginlet surface 27 guides the insertion of the yarn end towards the center of thepipe 20 and optimizes the suction, reducing losses. Thelinear actuator 30 may be extended to bring thelower pipe 22 close to the bobbin. - If the yarn end has been separated from the bobbin, the
photocell 29 detects it (Figure 3 ). Optionally, thelower pipe 22 may be further lowered to even further near the suction pipe to the bobbin. - Subsequently, the mechanical
gripping device 28 closes on the yarn and captures the yarn end (Figure 4 ), by grasping it mechanically. - The telescopic movements of the suction pipe, as well as the opening and the closing of the gripping device, and the activation of the cutting
device 25, are produced as a result of commands imparted by a processing unit - for example a Programmable Logic Controller (PLC) or a Central Processing Unit (CPU). The processing unit receives response signals from thephotocells apparatus 10 in its entirety, thus also the operation of all other engine/actuating parts herein described. - Once the yarn end is clamped by means of the
gripping device 28, thelower pipe 22 is raised, forcibly further separating the yarn end from the bobbin (Figure 5 ). - In this situation, the suction in the
upper pipe 21 is sufficient to pull a further yarn portion out of the bobbin. The mechanicalgripping device 28 therefore opens (Figure 6 ) and allows thepipe suction 20 to extract another yarn portion from the bobbin. - Optionally, a
palette 44 may be brought into contact with the bobbin in order to prevent the suction of an excessive length of yarn. - When the
upper photocell 24 detects the presence of the yarn in theupper pipe 21, the cuttingdevice 25 cuts the yarn end (Figure 6 ). The suction by means of thepipe 20 is interrupted. - Once the yarn end is cut, the
lower pipe 22 may be optionally lowered almost getting in contact with the tube of the bobbin (Figure 7 ). The palette, if provided for, may be left in contact with the surface of the bobbin, holding the yarn thereagainst. Once the suction from the top by means of thepipe 20 ceases, a suction from below is activated, by means of the support plate 40 (Figure 7 ). With 34 a suction sleeve is schematically indicated. Consequently, the yarn end is sucked inside the tube by means of the upper end B thereof. Thesurface tapering shape 27 facilitates the introduction of the yarn end in the top of the tube. - According to one embodiment, to more effectively insert the yarn end into the tube, the suction from below by means of the tube is associated with the activation of one or more nozzles 33 (
Figure 7 ) mounted in thelower pipe 22. Thenozzles 33, optional, blow one or more compressed air jets downwards, inside thelower pipe 22, thus assisting the suction action by means of theplate 40. - According to a variation not shown, the
nozzles 33 may be mounted on lower or outer part of thelower pipe 22, for directing one or more jets downwards. - Once the yarn end is inserted in the tube, the bellow-holder ring and the suction pipe are lifted, freeing the bobbin (
Figure 8 ). - Experimental tests carried out by the Applicant have shown that satisfactory results are obtained even in the absence of a
second photocell 29 provided for in thelower pipe 22. The mechanicalgripping device 28 may also intervene in the absence of a signal (given by the second photocell 29) indicating the presence of the yarn in thelower pipe 22. - If provided, the
second photocell 29 may be placed about 30-40 mm above thebottom mouth 26 of thelower pipe 22. - The
upper photocell 24 may be positioned a dozen centimeters (for example 15 cm) away from thelower end 23 of thestationary pipe 21. After the cutting, the yarn extracted from the bobbin must have a length sufficient so as to be introduced in the bobbin and remain there; indicatively (Figure 8 ), the yarn portion to be reintroduced into the tube may have a length comparable to the length of the tube. - The
gripping device 28 may be configured in different ways so as to effectively grasp the yarn end and be able to pull it and unwind it from the bobbin. For example (Figures 9 and 10 ), the gripping device may comprise two or more jaws ormovable shutter elements 28, for example in the form of blocks, acting inside thelower pipe 22 and controlled by twoactuators 35, mounted on thelower pipe 22. Theactuators 35 may be electrically or pneumatically operated, preferably operated by a single valve (not shown), which controls both the closing and the opening of themovable elements 28. The movable shutter elements may assume different shapes, for example crescent shapes or opposite V-shapes. - The
movable shutter elements 28 may slide radially in grooves or guides 36 integral with thelower pipe 22. -
Figure 11 shows a further example of a gripping device in which the movable elements comprise a plurality of radially arranged cooperating blades, as in an optical diaphragm. - During the yarn end P capturing step (
Figure 3 ), the taperinginlet surface 27 guides the insertion of the yarn end towards the center of thepipe 20 and, if neared to the top of the tube B, it optimizes the suction, reducing losses. In the step of inserting the yarn into the tube (Figure 7 ), the taperinginlet surface 27 almost in contact with the upper end B of the tube guides the yarn end to insert it in the top of the tube. - Various aspects and embodiments of the apparatus have been described. It is understood that each embodiment may be combined with any other embodiment. The invention, moreover, is not limited to the described embodiments, but may be varied within the scope defined by the appended claims.
