Description

The invention relates to a winding machine according to the preamble of claim 1.

Such a winding machine is z. B. known by the EP 1359 A1 and US Pat. No. 3,857,522. This can be the Spulspin on their revolver occupy a radially inner position. In this radially inner layer are the winding spindles or on it clamped sleeves from a centrally mounted drive roller driven. For the normal operation of the winding, the Winding spindles brought back into a radially outer position, where then the winding spindle with the sleeve mounted thereon or coil at a fixed and radially outside of the revolver rests on mounted roller. The revolver will then grow with the diameter of the formed coil against a einwir him kendes torque pivoted.

In the known winding machines hamper the Spulspin deln and the spooled spools on it, since the spool Spindeln a sufficiently large distance even with full coil have each other.

The object of the invention is a winding machine after the Preliminary part of claim 1 equip so that without Vergröße tion of the machine and without enlarging the between two similar machines to be complied with minimum division (minimum distance) particularly thick coils can be wound up.

The solution results from the characterizing part of claim 1, 2 or 6.  

The invention can be realized by three following concepts become:

Power / hold horizontal rotational position 1. Operating spindle outside Operating spindle inside Waiting spindle outside Waiting spindle inside 2. Operating spindle inside Operating spindle inside Waiting spindle outside Waiting spindle inside 3. Operating spindle inside Operating spindle inside Waiting spindle from the outside Waiting spindle inside further out

All concepts have in common that the horizontal rotational position driving through is with both winding spindles in the closest distance to each other. The winding spindles thus reach a so-called "Waist position" when using the spool turret by an in essential horizontal plane to be turned.

The solution has the advantage that each in operation located winding spindle during the entire Aufspulvorgangs (Spulreise) befin a well-defined operating position det. In this operating position, the bearing housing of the coil spindle in prism-shaped bearing shells safe, vibration-free and positioned exactly parallel to the measuring roller / contact roller become. For this are pneumatic or hydraulic force transmitters, z. B. cylinder-piston units or springs on the revolver provided that fixed the bearing housing of the respective winding spindle Press into such prism-shaped bearing shells. The bearings bowls are attached to the revolver. Only when the respective Spindle is put out of operation, it leaves their safe  Operating position and pivots on the revolver to the outside in one Evasive position. This creates space for the awakening sen of now re-forming coil. That's why it's special This is important because the new coil to be formed in the initial phase the winding travel in the diameter increases very quickly. By the invention enables the winding of larger coils and at the same time gained time to the coiled full spool of the winding spindle, which now in its radially outer Ausweichpo position is waiting to decrease.

According to EP 0 374 536 A1 (EP-1670) it is provided that the measuring and contact roller on a carriage or swingarm gela gert and with radial component to that in the operating position located winding spindle is movable. The rotary drive of the Revolver will depend on the evasive movement of the Contact roller controlled and continuous or step by step rotated so that the contact roller position in wesentli maintains. By the formation of the invention according to claim 7, it is possible to store the contact roller stationary. The Growth of the coil on the operating pulse spindle is caused by the Movement of the operating pulse spindle relative to the spool revolver sampled. Depending on this relative movement of the Rotary drive of the bobbin revolver continuously or in steps such activated that the Betriebsspulspindel opposite the Kontaktwal evades with the increasing coil diameter.

In the following the invention will be described with reference to FIGS. 1 to 4 be.

Figs. 1 to 4 show diagrammatically a view of the reeling machines in the following operating conditions:

Fig. 1 Both spindles are in their radially held ren position. The bobbin on the winding spindle is almost full.

Fig. 2 To change bobbins, the turret has been rotated so far that now the other winding spindle with the empty tube on it is in contact with the measuring roller and is in the operating position. The winding spindle with the now full coil is in its waiting position. The thread is still wound on the full bobbin, but already wraps around the empty tube on the other winding spindle.

Fig. 3 The thread is now wound on the winding spindle in contact with the measuring roller. The winding spindle with the full spool has been introduced into its radially outer position ver and is now ready to take off and from transporting ready.

Fig. 4 The winding spindle located in the waiting position has been brought back into its radially inner position.

The following description was created in the event that

• a) Operating spindle and empty spindle an inner position when the operating spindle is in winding mode and
• b) the former operating spindle goes to outer position, when the former empty spindle in the winding operation goes.

It should be expressly stated that this description ent to apply speaking is for the two ande mentioned above ren concepts of the invention.

A freshly spun and / or drawn yarn 1 is delivered by a godet 2 at a constant speed and guided by the yarn guide 3 . The yarn guide 3 represents the tip of the so-called traversing triangle. In the traversing triangle, the yarn is guided back and forth by a traversing device 4 over a given length transversely to its running direction. The thread then passes to a measuring and contact roller 5 and wraps around it at an angle of z. B. 60 to 90 °. The contact roller 5 is in circumferential contact on a sleeve 6.1 or a coil formed thereon 10.1 . The sleeve 6.1 is clamped on a flying-mounted winding spindle 7.1 . The winding spindle 7.1 is driven by an axle drive motor (spindle motor), not shown here. In this case, the spindle motor is controlled in dependence on the rotational speed of the measuring roller 5 such that the rotational speed of the measuring roller 5 remains constant.

The winding spindle is mounted on a revolver 8 . The revolver 8 is rotatably mounted in the machine frame in ball bearings or roller bearings 9 . The revolver is driven by a revolver motor 33 . Control of the turret motor will be described below. On the turret 8 are a total of two winding spindles, on the one hand, the previously described winding spindle 7.1 and the other winding spindle 7.2 stored. The winding spindle 7.1 is - as already described - in the operating range and is therefore driven. The winding spindle 7.2 is in its waiting area and is currently not driven.

Each of the winding spindles 7.1 and 7.2 is mounted on the revolver at the one end of a respective bearing rocker 11.1 and 11.2 . Each of the bearing rockers 11.1 , 11.2 is connected at its other end to the revolver by a pivot bearing with pivot axis 12.1 and 12.2 . A force transmitter 13.1 and 13.2 attacks on the one hand at the respective free end of each bearing rocker and on the other hand on the revolver. By the action of the force transmitter each bearing rocker - relative to the turret 8 - pulled radially inward and tion in a radially inner posi (storage position) determined by appropriate stops. These stops are preferably formed by the fact that on the turret - in Fig. 1 only schematically shown - bearing shells 18 are mounted, which are prism-shaped. The bearing housing of each winding spindle is pressed len in the radially inner position of the bearing rockers in these prism-shaped Lagerscha and thereby stored defined. In particular, this ensures that the Spool spindle in operation is aligned exactly parallel to the contact roller 5 .

It is described in EP 0374 536 A1, that the contact roller 5 is mounted on a carriage or a rocker 48 relative to the machine housing nengehäuse movable. The movement of the carriage or the rocker is scanned by a sensor 52 . The turret drive is controlled in response to the output of the sensor such that the in-service coil with its growing bobbin diameter of the remaining substantially in its original position contact roller 5 evades. FIG. 1 located in EP 0 374 536 A1 is the subject of this application as FIG. 5, including the description there. In FIG. 5, the following machine parts are accordingly provided with the following reference symbols:

In the following, the function of the winding machine is in phase of the bobbin change described:

In Fig. 1 it is shown that the coil in operation has almost reached its desired thickness. The target thickness of the coil is given by the risk that the coil grows against the empty tube 6.2 , which is spanned on the other winding position located in their Lagerpo 7.2 . For Beendi supply of Aufspulbetriebes on the winding spindle 7.1 of the turret 8 is rotated by the drive motor so far that the coil 7.1 loses contact with the contact roller 5 and enters the waiting area. This condition is shown in FIG . As a result, the winding spindle 7.2 with the empty tube 6.2 clamped onto it comes into contact with the contact roller 5 and has thus reached its operating range. During this turning operation, the thread continues to run up to the already full bobbin 10.1 , so that the empty tube 6.2 on the now be in operating position sensitive winding spindle 7.2 is partially wrapped by the current thread. The thread is now brought in circumferential contact with a catch slot which is mounted on the empty tube 6.2 . For this purpose, reference is made in detail to EP 0 374 536 A1. Because the thread is caught on the empty tube 6.2 , it tears off between the empty tube 6.2 and the full bobbin 10.1 . Now, the winding spindle 7.1 is braked by a brake, not shown. Subsequently, it is expected that an operator or a machine apparatus will remove the full bobbin 10.1 from the winding spindle 7.1 and at the same time plug an empty tube for the new operation. During this time, a new coil is formed on the now in operating position Spulspin del 7.2 with the empty tube 6.2 clamped thereon. Due to their small diameter, the diameter of the new coil grows very fast. There is therefore the danger that the new coil grows against the full bobbin 10.1 . For this reason, in the winding machines in which the spool spindles are fixed at a fixed distance on the revolver, the target thickness of the coil also limited by the fact that is always expected to a certain waiting time to the decrease of the full package. In addition, disturbances in the operation must be taken into account. This is especially true when automatic operation by mechanical control units is desired. According to a possible of three concepts of this invention is now provided that the winding spindle located in the waiting position of the bobbin 8 7.1 is brought into a radially outer position (avoidance position). For this purpose, the corresponding force transmitter 13.1 is pressurized in its pressure chamber 14 .

As a result, the bearing rocker 11.1 is pivoted and the Lagerge housing the winding spindle 7.1 lifted from the corresponding bearing shell 18 . This condition is shown in FIG . Now there is an enlarged space available for the growth of the new coil. On the other hand, the waiting time was increased to remove the full bobbin 10.1 .

When the full bobbin 10.1 has been removed, the winding spindle 7.1 is again brought into its radially inner storage position by corresponding activation of the force transmitter 13.1 , according to this embodiment. In this radially inner layer, the bearing housing of the winding spindle 7.1 is fixed again and exactly posi tioned in the prismatic bearing shell 18th This condition is shown in FIG .

In a further development of the invention it is provided that the contact roller 5 is stationary and not stored in a rocker. In this case, each bearing rocker 11 is connected to a sensor 52.1 , 52.2 . This sensor detects the pivotal position of each bearing rocker 11 relative to the revolver. 8 On the other hand, the respective force transmitter 13.1 , 13.2 is acted upon by a contact force, on the one hand compensates the bearing on the bearing rocking torque, on the other hand causes an optimal constant contact pressure of the contact roller on the coil. The drive motor of the turret 8 is now in speed depending on the output signal of those of the sensors 52.1 , 52.2 , which detects the growth of the respective operating pulse 7.1 , controlled so that the relative position of the arm concerned substantially unchanged and changes only in the millimeter range ,

In Fig. 6, which corresponds to the rest of Fig. 1, the Senso Ren 52.1 , 52.2 , the turret motor 33 and the required switching and control device are indicated schematically.

Fig. 7 shows this deviating an embodiment in which both winder spindles 7.1 , 7.2 are in a radially outer position, as long as the operating spindle is in the winding operation. For this purpose, the prismatic bearing shells 18 limit the pivotal movement of their associated bearing rockers 11.1 , 11.2 to the outside and are arranged to swing radially outside the bearing for this purpose.

Once the coil formed on the operating spindle is full, the turret 8 is rotated. At the same time, or shortly before, a movement of both winding spindles into the inner position takes place.

When the spindles pass through the horizontal plane, that is Moving the spindles so far done that this their take the closest distance.

After passing through the narrowest position and corresponding further rotation of the revolver 8 , the former empty spindle 7.2 is accordingly the predicted in the winding operation and the former operating spindle can be operated by the decrease.

For this purpose, the winding spindles before or at the most to shortly after the start of the winding operation in the outer posi tion, to the incoming thread on disability wind up.

A special feature of this embodiment is the synchronous Traveling movement of the two winding spindles.

This synchronous movement is generated in the present case with means of the cylinder-piston unit 13.0 . The cylinder-piston unit 13.0 sits on the revolver. 8 The stroke of the cylinder-piston unit is implemented via a pair of toggle levers 20.1 , 20.2 in synchronous radial movement.

For this purpose, each of the toggle is hinged at one end to the cylinder-piston unit. Each of the toggle levers is articulated on its winding spindle or here on its bearing rocker 11.1 or 11.2 with the other end.

Both knee levers form a V.

It can be seen that during a lifting movement of the cylinder-piston unit both toggle must follow this lifting movement. On the other hand, the toggle lever pivotal movement of the bearing is swinging 11.1 , 11.2 forced, which move in the extended stroke movement diverge a radial movement of the bearing and vice versa takes place.

This toggle lever system in combination with the outer bearing shells 18 causes a firm clamping of the winding spindles in the radially outer position. The occurring high forces are conveniently introduced into the turret 8 , the end wall for this purpose, - by z. B. end wall stiffeners -, is stabilized. Another possibility is that the entire suspension of the bearing rockers, the cylinder-piston unit and the bearing shells are arranged on a special chassis, which is then attached to the revolver.

The radial inner layer can be approached in two different ways be ren. In one case the cylinder is double-acting Cylinder is formed and is pressurized on its other side applied.

In the case shown, there is the special feature that the cylinder-piston unit 13.0 is acted upon by a biasing force acting spring 19 in the direction of retraction movement of the winding spindles in the radially inner position. It is therefore sufficient to relieve the pressure chamber 14 to spend the winding spindles in the radially inner position.

The advantage of this design is that in case of pressure failure, an automatic movement of the winding spindles takes place and therefore a collision between the coils / winding spindles adjacent equal-like machines is always prevented upon rotation of the turret 8 for bobbin change. The spring 19 should therefore be designed so that its biasing force is sufficient to approach the radial inner layer.

Another advantage of this concept is that the empty spindle can be driven through in an inner position under the contact roller 5 back. The lifting of the contact roller can thus be saved.
