M i 0 W n nf? a ,2 2 A w x/v HG United States Patent Oflice 3,131,879 Patented May 5,, 1964 The present invention relates to a yarn winding machine for rewinding the yarn from bobbins, for example the cops of spinning frames and the like, into bigger spools such as cross-wound cones.
This invention more particularly relates to a winding machine of this type which is provided with a device for supplying, in case of a yarn rupture, the yarn ends to a knotter, which device comprises a suction-tube bent partly around the knotter and cut open at the inside of the bend, and two suction openings for sucking in the two yarn ends.
It is the object of the invention to produce a Winding machine which is reliable and of simple construction.
Another object of the invention is to provide a winding machine in which, at an interruption of the yarn transport, both in consequence of yarn rupture and when one of the bobbins has to be exchanged, the yarn ends of the bobbin which is to be unwound and of the spool which is to be wound can both be sucked up through the suction openings and fed to the knotter.
For this purpose it is possible in the winding machine according to the invention for the suction openings to cooperate With the surface of the bobbin and with that of the spool, and the suction openings are formed by the two ends of a guiding tube through which the yarn passes during rewinding, and to which the suction-tube is connected sideways.
Preferably, a valve is provided in the guiding tube, which valve is provided with a slot for the passage of the yarn and which, dependently on its position, closes the guiding tube either on the one side or on the other side of the connection of the suction tube so that the yarn ends of both bobbin and spool can be sucked off one after the other.
The invention will be illustrated below with the aid of the accompanying drawing, in which:
FIG. 1 shows a front view of the winding machine during rewinding, partly as a cross-section;
FIG. 2 shows a side view of the winding machine during rewinding;
FIG. 3 shows a front view of part of the winding machine while the yarn end is being sucked oif from the bobbin which is to be unwound;
FIG. 4 shows a front view of part of the winding machine while the yarn end is being sucked off the spool which is to be wound;
FIG. 5 shows a side view of the winding machine in the position according to FIG. 4;
FIG. 6 shows a front view of the complete winding machine and FIG. 7 shows a side view of a complete winding machine.
The FIGURES 1 and 2 show the relative positions of the parts of the winding machine while winding yarn from the tube 1 to the cone 2 driven by the drum 3. Herein the yarn runs successively through the outer tube 4, to which the suction tube 5 is connected, and the inner tube 6, which is movable inside the outer tube 4.
The packings 7 ensure an air-tight connection between both tubes. The inner tube 6 at its bottom ends in a tapering nozzle 3 and is closed off at the top by a plate 9, which is provided with a narrow slot. A little below this plate 9 is disposed a lateral opening 10, which can correspond with the connection opening of the suction tube 5.
The said suction tube 5 has a semi-circular bend. Within the space, which is limited by the tube 4, the tube 5 and the covering plates 11, is positioned a knotter 12.
In the sides of the tubes 4 and 5 which are turned to- Wmds the knotter, narrow cuts 13 and 14 are provided,
which serve to guide the yarn towards the knotter.
The yarn 15 runs from the tube 1 by the slubcatcher 16 to the cone 2. At yarn ruptureeither spontaneous, or caused by the slubcatchers reacting to the presence of a slub and consequently cutting the yarnone yarn end is wound on to the cone 2, whilst the other end remains hanging from the tube 1.
The yarn feeler or scanner which is not shown in the drawing and which can either be of the known mechanical type, or work with a measuring condenser or a photoelectric cell, an electronic slubcatcher also being able to perform this functionannounces thread rupture by a signal. This signal brings about a reaction from a control mechanism, which starts a suction device which is connected with the suction tube 5. Hereby the loose yarn end of the bobbin is sucked into the tube 4. It then assumes the position shown in FIG. 3 in which it passes through the knotter 12.
At the same time the hingingly suspended slubcatcher 16 is turned away and the cone 2 is turned right under the nozzle 8. In this it is necessary that the surface of the cone should be inmiediately under the nozzle 8. The observation of this situation may be effected by means of a photoelectric cell which is exposed to a beam of light to be intercepted by the cone, or by means of a mechanical feeler; it is also possible to limit the movement of the cone by means of fixedly positioned supporting rollers. A slip coupling which is connected to the shaft of the cone, couples the cone to a small electromotor, which after the moment of standstill has been passed, drives the cone in a direction opposite to the turning direction during winding. By means of the partial vacuum in the tube 6, the loose yarn ends are removed from the cone by suction and laid across the knotter 12.
This situation is shown in the FIGURES 4 and 5.
A signalling device (not shown) gives off a signal when the thread lies in the knotter 12. At this, the cone is stopped and the knotter 12 is put into operation, so that the loose yarn ends are knotted together. These yarn ends are so long that any slubthe presence of which has caused the slubcatcher to reactis to be found in one of the loose ends and is consequently sucked off together with these ends.
After this the cone swings back again to its starting po nt, the suction device is stopped and the cone is driven by the drum. Winding continues in the normal way.
It is clear that, at the occurrence of rupture during winding the yarn end which is connected to the bobbin is still present in the inner and outer tubes, and can, therefore, easily be sucked towards the knotter. However, the winding machine according to the invention is meant to be a full-automatic winding machine, to which bobbins can be supplied. This implies that the machine m st be able to find the yarn end in each new bobbin. For this purpose the outer tube 4 is slidable in longitudinal direction with respect to the inner tube 6. After a new bobbin has been put on, the outer tube 4 is moved upwards and then partly encompasses the bobbin 1. This situation is shown in FIG. 3. The plate 9 of the inner tube 6 now shuts oil the outer tube 4 below the suction opening; substantially the whole of the suction force of the suction device is employed to suck the yarn end off the bobbin and supply it to the knotter.
In the above description and the corresponding figures the suction system of the winding machine is explained merely diagrammatically. However, constructively simple solutions can be applied to the various functions to be performed, as these functions are essentially simple. In this way the overall construction of the winding machine becomes particularlyuncomplicated and the machine will have an excellent reliability.
The FIGURES 6 and 7 show a winding unit according to the application with the driving and control apparatus belonging to it. It is easy to recognize the upper tube 4, the lower tube 6 with the nozzle 8 and the suction tube 5, as also the drum 3 and the cone 2, which latter is shown in the position it has when the yarn end is being sucked off. The cone 2 is carried by two arms 17, which are hingingly connected to two arms 19 at 18. These arms 19 are rotatable about an axis 29, their rotation being controlled by a motor 21, reduction gear 22 and chain '23. a.
7 By the action of a spring 24 and the weight of the cone 2, an extension 25 of each arm 17 is pressed against an eccentric wheel 26, which can be driven by a motor and reduction gear 27.
During the rewinding the cone 2 and the arms 17 and V are in the position as shownin broken lines in FIG. 7. The cone 2 is pressed against the drum 3 by the action of the spring 24. At'the same time the slubcatcher 16,
' which is carried by two arms 28 rotatable about the axis 20, is positioned under the nozzle 8.
When the yarn end of the cone 2 is to be knotted to the yarn end of a bobbin 1, the arms 17 are rotated clockwise to the position shown in full lines. By means of a cam on the arms 19, the arms 28 are rotated clockwise size of the cone 2.
a 4 I V The up-and-down movement oithe upper part 4 of the guiding tube is obtained from the rotation of an eccentric wheel 29, driven by a motor and reduction gear 30 and cooperating with an arm 31 which is rotatably mounted at 32 and carries the upper part 4 of the guiding tube.
A mechanism for replacing full cones by empty ones is generally indicated at 33. a
The suction tube 5, as shown in FIG. 1, may be con nected to any suitable device for creating a suction such as a suction pump 34 showndiagrammatically in this figure. Of course, any means can be utilized for creating a vacuum and thus, the suction pump is merely shown as one form: of device that can be used.
