Spooling device for textile machines.

The invention relates to a yarn winding device for textile machines, in which the yarn on a rotatable bobbin under control of a longitudinal direction this core back and forth guide is wound up and control arrangements are provided by means of which the Movement of this yarn guide is controllable. The coil core can, for example, consist of a continuously cylindrical one Pipe exist or this pipe can carry a splash at one or both ends.

In the manufacture of different coil forms, as they meet the various needs in the textile industry, there is an object that you can select the path must, on which either the ^r // eglUnge the guide along the spool core or the profile of the distance traveled by the guide Distance compared to the bobbin core or both factors can be changed simultaneously during the winding process »

_ The invention solves this problem in that ^ mung the path length of the thread guide or an associated one Organes two limit switches are provided, one of which at least one is arranged adjustable in the longitudinal direction of a rail, which in turn during the winding process is progressively adjustable practically parallel to the setting of the limit switch,

It is useful to determine the extent of the displacement of this rail during the winding process Presettable limit or stop switches provided, the rail between these limit or stop switches vor or can be moved back, for what purpose a Umschaltfe ble motor or a geiegnete indexing arrangement can be provided

Both limit switches are preferred to determine the Path length of the thread guide adjustable on the rail, and According to a special proposal, at least one of these limit switches can be switched off.

With the aid of the device according to the invention, the most varied of items can be carried out on a single textile machine Manufacture formations of yarn bobbins.

Usually a textile machine has a large number of coil metals, their reciprocating or revolving Guides are moved together. Controlling the movement the yarn guides usually takes place via an element which is connected to the guides in such a way that it moves in the same direction as these, influencing the drive of this organ. With a ring spinning machine for example, it is controlled by the movements of the hanging bench, which the rings for the runners carries, whereby the drive of this ring rail is influenced.

Electrical, hydraulic or pneumatic switches can be used as limit switches.

Ii becomes a preferred embodiment of the invention Explained in detail using the accompanying drawings; show it:

The control shown in Figure 1 for a winding device controls the reciprocating movement of a Or.ganes (10) in the direction of arrows 11 _β In the organ IO it may, for example, the ring rail of a ring spinning machine or to a reciprocating Acting organ through which the yarn guides of other textile machines are guided back and forth in the longitudinal direction of the bobbins.

In the. Application of the invention shown in FIG In the case of a ring spinning machine, this element 10 is thus the ring rail of the ring spinning machine. This ring rail 10 is raised by a pressure medium-actuated working cylinder 30, its piston rod 31 by means of a chain wheel 33 running chain 32 connected to the ring rail is. The ring rail 10 is lowered by its own weight, the working cylinder being switched in such a way that that it is vented in this case. The pressure medium supply this working cylinder is controlled by a changeover valve 34, which in turn is controlled by the control mechanism 35.

The ring rail 10 carries several ring guides 36 for the W runners 36a. The ring guides 36 are moved back and forth by the movements of the ring rail in the longitudinal direction of the coils 37, each of which is seated on a rotating spindle. The spindle sits in a neck bearing 38 on the spindle bench 39 and carries a whorl 40 which rests on a drive belt 41. The yarn to be wound onto the bobbin 37 is drawn off from a roving bobbin 42 and runs over conventional guides.

The control device for the winding process has two Limit switches 12 and 13, which are on stop bars 14 and 15 are attached along a rail l6 are adjustable and can be locked on this rail by adjusting screws 17 to define the space between the two limit switch contacts., The limit switches 12 and 13 are controlled by the organ 10, in this case the ring rail, operated or by a corresponding organ, which is in the same direction as' (J.

The rail 16 can be displaced in its longitudinal direction by a spindle 18 which can be set in rotation by a motor 19. This rail 16 is assigned a second pair of limit switches 20 and 21 on corresponding brackets 22 and 23, the spacing of which in the longitudinal direction of the rail 16 can be selected by adjusting these brackets along a rail 2k and locking Jn in the corresponding position using adjusting screws 25 Limit switches and 21 take place through the stop bars Ik and »15, respectively.

The bracket 23 also carries a limit switch 26, which by the ring rail 10 or another machine « organ can be operated.

As a drive, a switchable motor 19 is expediently used, which run continuously or by a Pulse generator 27 can be switched step by step »

This control mechanism can be used to control the Wind a wide variety of spool shapes on a single machine. . -

For example, in order to be able to produce the "coil" shown in FIG. 2b, the desired path length of the organ 10 is set by setting the limit switches 12 and IJ) along the rail 16 according to the length "iß (FIG. 2a)

The motor can either run continuously or be switched step-by-step, in which case one or both switches 12, Ij5 can also be designed in such a way that the unit 27 is excited via them, so that with each excitation the motor in the corresponding direction by a number Pulses from the unit 27 are switched step by step according to the desired number of the reciprocating movement of the organ 10 per cycle of the rail 16

To produce a "bottle spool" (FIG. 3b), the setting is carried out in the same way as during production the traveling coil with the only exception that the limit switch 13 is turned off by, for example by pivoting on the rail 16 out of the path of the Organ 10 is brought out, so that the inversions of the organ 10 and the excitation of the motor on the corresponding ■ The end of the path of the organ 10 can be influenced by the limit switch 26.

To produce a "double flange bobbin" (Pig, 4b), the motor 19 can be switched off and the winding process can be controlled by the limit switches 12 and I ^ alone to produce a reciprocating movement "L" (Fig. 4a) corresponding to the distance between the two flaps On the other hand, in order to avoid the formation of bulges next to the splashing of the coil, the rail 16 can be cyclically moved a short distance by the motor, so that the reversal points change cyclically by a distance ⁿ t ⁿ (Fig. 4a). In this mode of operation, the control is set in the same way as for the traveling coil, with the exception that the "traveling" is much less «

To produce a "contactor coil" (FIG. 5b), the two ends of which are tapered, the switches 12 and 15 are set in such a way that they ^{measure the organ 10 a path ™ l tr} (FIG. 5a) which is considerably shorter than that Length ¹¹ L "of the coil core (Fig. 5b), and when the holder 10 is actuated, the pulse generator 27 is switched on to control the motor 19 in such a way that it moves the rail 16 at one limit of its movement to the other by a very short distance When the member 10 is hydraulically moved by a reversible working cylinder, the active limit switches can energize solenoids which control hydraulic reversing valves.
