The spool holding arms carry a freely movable one at one end Opposite tip for centering the spindle and opposite this cone is the device for locking and unlocking the Spindle.

As mentioned, the bobbin holding arms can also rotate within an axis which is parallel to the spindle axis and Take angle adjustments in the plane that is practically perpendicular to the plane of the holding arm itself.

According to the current state of the art, there are automatic package winder, which are provided with bobbin holding arms with counter tips.

These machines are operated almost exclusively by machine; this has the disadvantage of requiring more space Machine construction · and further the disadvantages of the low reliability of transmissions with complicated lever devices.

Further associated shortcomings are the increased need for maintenance with the resulting loss of production and the need for operator intervention at the end of winding.

There is also no centering of the spindle, which is almost absolute

BQ9816 / 0887

BATH

Reliability is guaranteed, and the spindle cannot be changed either be locked.

One is also missing from the spool holder arms with the same end use Winding arrangement independent of the winding reserve.

The aim of the invention is to reduce the amount on the automatic package winder Care to be performed both in relation to maintenance before commissioning as well as for maintenance after winding has been completed.

Another aim is to create a device which allows the supply reel to be wound independently and automatically the spindle allows.

For this purpose, it is recommended in known arrangements to wind the first thread turns on the spindle in order to get the thread to be attached to the spindle and to facilitate the winding work from the first turns.

The invention also aims to simplify and reduce the size the bobbin removal device and the resulting reduction in the space required by the automatic package winder.

It is also intended that the spindle between the counterpoints

509816/0887

can be centered automatically.

It is also an object of the invention, after centering has been achieved, to secure the tube between the counter tips in a secure manner.

Another goal is to make it easier to package, shed, Doubling by means of a slot cylinder (thread cleaner) and thread guide from the first turns.

A winding machine that is able to automatically attach the yarn to the spindle is advantageous.

It is also advantageous to let the first reed twists automatically wind up directly from the bobbin holding arm.

Another advantage is the automatic centering of the Tube through the opposing tips.

It is also advantageous to attach the tube to the opposing tips. Another advantage is the automatic and independent Removal of the finished spool.

Finally, it is advantageous to set the winding process in GAng with yarn already wound on the tube.

Further advantages that are indirectly derived from the proposed

S0981 6/0887

Deriving improvements are a reduction in space requirements and increased operational reliability.

The described and other and further objects and advantages are accentuated by the improvements to the bobbin support arms with counterpoints especially for automatic package winder with essentially "C" -shaped arms and the bobbin axis practically resting on the arm plane and existing freely movable counter-tip, marked by the following parts:

- A second freely movable, axially movable, towards the end expandable, to the other freely movable counter-tip coaxially and opposite to it arranged counter-tip,

- a temporary (intermittent) on the second free mobility

Counter-tip acting drive member,

- One movable in a plane parallel to the plane of the bobbin holding arm Arm for automatic adjustment (placement) of the reserve spool.

A further improvement is achieved in that the mentioned second freely movable and axially adjustable counter-tip with a device for independent axial displacement is equipped. "

Further goals and improvements result from the following

FIGS. 10 and 11 show two side views of the device according to FIG. 9.

In the various figures listed, the same parts with the same functions are given the same reference symbols differentiated.

In Fig. 1, Io denotes the "C" -shaped arm with counterpoints. This Arm is illustrated here only with the front part, to which the improvements according to the invention relate. The rear part, not shown, can be made according to any of the solutions known in the art. As mentioned, the arm can rotate radially and at the same time to that perpendicular to the arm and passing through the axis A-A Swing level. All of this is known in the art and is performed on the known types of machines.

On this arm, the spindle 11 is mounted between the freely movable counter-tip 12 and the device according to one of the improvements, which is denoted by 13 and which will be described below. The scissors 14 are also shown schematically, which are active when the finished cheese is ejected in order to cut off the thread end 28 and to take up (hold) the end of the thread still to be wound.

509816/0887

The locking and unlocking device of the spindle 11 is in Fig. 1 in the locking position and in Fig «2 in the unlocking position reproduced »

In the device 21 is the ring cap of the freely movable Ring bearing 22f in the middle part between the cap

21 and the bearing 22 is a chamber 2o which is connected to a source of liquid under pressure via the line 19 stands; 26 is the fixed shaft which is coaxial with the freely movable support 22 and by means of bearings 37 are the same mutually assigned? the chamber is sealed by means of plug 391 with 24 are the pins that are arranged on the circumference between the bearing 22 and the cap 21 and which, by means of the ring 38, the cap 21 resiliently against * press the bearing 22 ,, whereby between ring 38 and cap 21 a spring 23 is inserted for each pin 23 »25 is the ring element made of elastic material that is exposed between of the cap 21 and the bearing 22 withstands the pressure and has a smaller diameter than the interior of the spindle 11 has, while when squeezing 25 between 21 and

22 its diameter increases, creating the desired lock by. Clamping occurs »

The La ^ e marked with B (Fig. 1) is thus a locking division, while the "it G ibüSdicfenete (Fig. 2) an unlocking ·; position represents «The NOOT ^ position is the yon Bj to go over to position C , is through, the opening la liquid

admitted under pressure, which fills the chamber 20 again and removes the parts 21 and 22 from each other. Such a position is maintained as long as liquid is introduced under pressure. At this point, with the spindle 11 free, action is taken to release the bobbin 35 and only the spindle 11 so that the shaft 26 is displaced backwards and takes the entire device with it. In this way, the bobbin is released and the machine prepares to receive a further spindle - which is adjusted as a result of the advance of the shaft 25 actuated by the counteracting spring 27. When the pressure fluid is removed, the two parts 21 and 22 are brought closer to one another again by the springs 23, which are pressed together by the tie rods 34. This approach brings about the elastic squeezing of the seal 25, which increases its diameter and the spindle 11 locks. A further improvement can be seen in the following, which allows the shaft 28 to be set back and advanced using the means inherent in the bobbin holding arm. Whenever the reciprocal setting of the scissors 14, the thread to be wound 28, the spindle 11 and the counter tip 13 is such that the counter tip 13 is set back and the spindle 11 is attached to the counter tip 12, the su bobbin and cut thread , which is held at the same time by the scissors 14, is located between the end faces of the spindle II and the counter-tip 13, the situation arises that when the device is released, which moved the counter-tip 13 backwards under the pressure of the spring 27 _? the counter tip 13 advances _f the

Compresses thread 28 within the spindle and by expansion of 25 the thread to be wound 28 and the spindle 11 blocks.

It follows that when the part 22 is urged forward by the spring 27, the thread 28 remains locked between the seal and the inner surface of the spindle (see Fig. 4). According to the invention, a first phase of winding the thread 28 onto the spindle 11 is provided before this is in contact with the driver cylinder, namely in order to obtain the desired under-winding reserve. 44 for fastening the reserve thread 44, which also has the task of Protect the spindle from wear and tear from initial contact with the driver cylinder .

In this phase the spindle is driven by a small turbine moved, which (Fig. 7) is set in circulation by the compressed air blown through the tube 29. This jet of air der.die applied to the circumference of the ring bearing 22 pin 4o, supplies the arrangement with the desired torque and consequently the required speed of rotation.

The air jet iat on the duration and pressure height adjustable and can be maintained as long as _e is not lowered to the Mitnehmersylinder to or almost to the spindle, thereby finally the danger herafef © will reduce that the spindle yQn the * velocity lull © almost zero on "put into circulation" Om the reserve is exactly below the flush, ie

in the desired preferred position, a further improvement has been made to the bobbin support arm, which is to provide a means of vane movable arm 18 which picks up suture 28 which is in any position within the "C" -shaped arrangement of the Armes Io and the spindle 11 is present and brings him into precise position and keeps him in the same for the entire time required.

The rotation of the arm 18 within the axis Q takes place through the action of the piston 17. This arm 18 is moved from the rest position E. (Fig. 4) 'IrJdIe position G (Fig. 5) brought and forces the thread for winding on the part of the spindle with larger diameter, whereby the underspool reserve that fixes the thread on the spindle is brought.

Fig. 6 shows a section through the device which ensures the formation of the subapuloid reserve. .This device consists of a cylindrical shaft with a series of teeth to act as a rack _? this shaft 16 being actuated by the piston 17 and meshing with the pinion 15 to which the arm 18 is firmly connected, which is therefore set in rotation within the axis Q 'with the piston 17 advancing or retreating.

FIGS. 10 and 11 are two side views of the device according to FIG FIg. 9. This device consists essentially of one Piston 3o acting on the arm 41 with the center in S, which is coaxial with the cam 31 and also with the arm 41 of FIG Arm 34 is firmly connected, which carries the small angle 35 placed at the end with storage in 42. This angle is with firmly connected to the outer end face of the shaft 26 by means of an axially drilled screw nut 43. The cam 31 is with a Approach 32 is provided, which acts on an air valve 33, which is used to regulate the supply of the chamber 2o (Flg. 2) through the in the Shaft 26 yorhanden e hole 19 is used, whereby the separation of parts 21 and 22 (Fig. 2) and accordingly the unlocking of the spindle is effected.

The piston 3o actuates via the arm 41 also the rotation of the lever 34 within the axis 5, which on the shaft 26 by means of Winei ^ L 35 works by making him step back and with it that Eject the bobbin as previously described.

The spool can also be removed by hand by acting on the lever 43 firmly connected to 42.

The illustrated and described solutions to the improvements represent a preferred embodiment of the invention.

Form, dimensions and proportions of the individual parts of the whole can therefore be changed; the situation to one another is the same the fluid used in the circuits can be air, oil, water be; or the locking and unlocking as well as the other processes actuated by compressed air can be done mechanically, as well as other factors obvious to those skilled in the art can be modified without exceeding the protection area.

It is also possible ^ the arm with all or part of the improvements to be used in unwinding, winding and rewinding machines, etc. or even in semi-automatic machines without the To exceed the scope of the invention. So it would be possible to modify the shapes of the bearing 22 and the annular cap 21, as well the turbine and this by a small induction. motor or by a fluid acting by means of a pinion or directly to be replaced with the bearing 22 acting as a rotor; It is also possible instead of the lever 34 and the angle 35 directly on the To use axis 26 acting piston, with 26 forming the shaft or the axis 26 with the piston shaft by means of a Connecting rod is connected? wd ^ eter it is still possible that the freely movable counter-tip 32 also withdraws in the removal phase; finally the arm 18 can move linearly etc ...

These and other modifications can thus be carried out without so that the scope of the invention is exceeded, '
