As such Operating units come for example Cross-wound bobbin changer, thread connecting devices or pneumatic cleaning devices in question. Also the Function of the existing ones on the winder Additional devices for making a thread connection are not impaired in their function if the units according to the invention are exchanged.

The drawings show exemplary embodiments of the invention. The invention is to be illustrated schematically with reference to the Exemplary embodiments explained and described in more detail will.

Fig. 1 shows the front view of two winding apparatuses of an automatic winder.

Fig. 2 shows the one winding apparatus in side view.

Fig. 3 shows the second winder in side view.

The cross winder is designated as a whole by ( 1 ). It has in particular a front end frame, not shown here, a rear end frame ( 2 ) and a support frame ( 3 , 4 , 5 ) which extends between the end frames. The two winding apparatuses are labeled ( 6 ) and ( 7 ).

The end frames have crossbeams ( 8 ) which carry supports ( 9 ). A travel rail ( 10 ) of a mobile operating unit ( 11 ) is attached to the supports ( 9 ). Another track ( 12 ) of the same operating unit ( 11 ) lies on the support frame ( 3 ).

The operating unit ( 11 ) is designed as a mobile automatic bobbin changer. This coil changer is only shown in FIGS . 2 and 3. It has rollers ( 13 ) and a motor-driven roller ( 14 ). Of the various other individual parts of the operating unit ( 11 ), only a swiveling cross-coil ejector ( 15 ) and a backward inclined rolling surface ( 16 ) are visible in FIGS . 2 and 3. The rolling surface ( 16 ) is aligned with a rear receiving trough ( 18 ) for completely wound cross-wound bobbins ( 19 ) and with rolling surfaces ( 17 ) or ( 22 ) which are provided on the individual winding apparatuses ( 6 , 7 ).

The winding device ( 6 ) has a frame ( 23 ) which is attached to the support frame ( 3 , 4 ). The winding apparatus ( 7 ) also has a frame ( 24 ) which is also attached to the support frame ( 3 , 4 ). The winding device ( 6 ) has a thread take-off point ( 25 ) for a take-off spool ( 27 ), a thread tensioner ( 29 ), a paraffinizing device ( 31 ), a thread traversing device ( 33 ), a rotatable friction bobbin drive device ( 35 ) for the package or cross-wound bobbin ( 20 ) and a spool frame ( 37 , 38 ) for holding the sleeve ( 41 ) of the package ( 20 ).

The thread drainage point ( 25 ) is located on the support frame ( 5 ). The thread tensioner ( 29 ) and the paraffinizing device ( 31 ) are attached to the frame ( 23 ). The thread traversing device ( 33 ) has a traction means ( 43 ) guided by rollers, which carries a thread guide ( 44 ) and can be driven by a motor ( 45 ). Further details of this thread traversing device are not shown here.

The winding device ( 7 ) has a thread outlet point ( 26 ), which is also located on the support frame ( 5 ). The thread drain point ( 26 ) carries a drain spool ( 28 ). The running thread ( 47 ) passes through a thread tensioner ( 30 ) and a paraffinizing device ( 32 ) in order to then arrive at the thread traversing device ( 34 ), which here is designed as a reverse thread groove in a rotatable friction spool drive device ( 36 ). The thread ( 47 ) then arrives on the package ( 21 ) forming a cross-wound bobbin, which rolls on the bobbin drive device ( 36 ) and is driven by the bobbin drive device ( 36 ) by friction.

The frame ( 24 ) of the winding apparatus ( 7 ) is also fastened to the support frame ( 3 , 4 ). It carries the thread tensioner ( 30 ) and the paraffinizing device ( 32 ). In addition, the frame ( 24 ) also carries a pivoted spool frame ( 39 , 40 ) which receives the sleeve ( 42 ) of the package ( 21 ).

While the thread ( 47 ) comes out of the sweeping thread groove ( 34 ), that is, directly from the thread traversing device to the package ( 21 ), this is not the case with the thread ( 46 ) of the winding device ( 6 ). There, the thread ( 46 ) first passes through the thread tensioner ( 29 ), then through the paraffinizing device ( 31 ) and then through the thread guide ( 44 ). From there, however, the thread ( 36 ) does not go directly to the package ( 20 ), but instead previously wraps around the roller-shaped friction spool drive device ( 35 ), and in the line of contact ( 48 ) of the spool drive roller ( 35 ) with the spool ( 20 ). it then runs tangentially onto the coil ( 20 ).

The thread traversing device ( 33 ) forms an exchangeable structural unit ( 52 ) with the bobbin drive device ( 35 ) and a holding frame ( 50 ). Also in the winding apparatus ( 7 ), the thread traversing device ( 34 ), the bobbin drive device ( 36 ) and a holding frame ( 51 ) form an exchangeable structural unit ( 53 ). The two units ( 52 ) and ( 53 ) can be interchanged. For this purpose, the frames ( 23 , 24 ) of the winding apparatus ( 6 , 7 ) each have the same position receiving points ( 54 , 55 ) in the form of dovetail guides for the structural units ( 52 , 53 ). The desired position, which ensures the correct winding package drive and the proper thread traversing, is ensured by fitting and holding elements ( 56 ) and ( 57 ). Both fitting and holding elements are designed as dovetails. The fitting and holding element ( 56 ) is located on the holding frame ( 50 ), the fitting and holding element ( 57 ) on the holding frame ( 51 ). The dovetails fit exactly into the dovetail guides, so that the structural units ( 52 ) and ( 53 ) and possibly also other structural units, not shown here, are interchangeable.

In the case of the units ( 52 ) or ( 53 ), the relevant bobbin drive devices ( 35 ) or ( 36 ) are arranged such that the line of contact ( 48 ) or ( 49 ) of the bobbin drive roller ( 35 ) or ( 36 ) with a sleeve or package, in the cases shown with the package ( 20 ) or ( 21 ), certain diameter on the winding apparatus ( 6 ) or ( 7 ) always occupies the same position. The same applies to the other winding apparatus and, if applicable, to further types and designs of structural units.

In the embodiments according to FIGS. 2 and 3, the position of the coil frame (37) and (39) and the size of the fully wound yarn packages (20) and (21) such that an empty tube (41) and (42) on the same contact line ( 48 ) or ( 49 ) with the corresponding bobbin drive roller ( 35 ) or ( 36 ) has contact as the fully wound package ( 20 ) or ( 21 ).

Only in FIGS . 2 and 3 is it shown that the winding apparatuses ( 6 ) and ( 7 ) have special thread return devices ( 58 ) and ( 59 ) for the purpose of producing a thread connection with the aid of an automatic thread connecting device, not shown here. The thread return devices ( 58 ) or ( 59 ) are suction pipes which are pivotally mounted on the frames ( 23 ) or ( 24 ) about pivot points ( 60 ) or ( 61 ). The two thread return devices ( 58 ) and ( 59 ) end in suction nozzles ( 62 ) and ( 63 ) which extend over the entire bobbin width and which can be set for the purpose of thread return of the package ( 20 ) or ( 21 ), as shown in FIGS is indicated by dot-dash lines Fig. 2 and 3. With the different types and designs of the units ( 52 ) and ( 53 ), both the bobbin drive device ( 35 ) or ( 36 ) and the thread traversing device ( 33 ) or ( 34 ) are arranged so that a predetermined movement path of the thread return device explained in more detail above ( 58 ) or ( 59 ) of the winding apparatus ( 6 ) or ( 7 ) remains free. In FIGS. 2 and 3, the mentioned movement path is indicated only by the end positions of the Fadenrückholeinrichtung (58) and (59). However, it can be seen from the drawings that the movement of the thread return devices ( 58 ) or ( 59 ) is not hindered by parts of the structural units ( 52 ) or ( 53 ). The thread tensioners ( 29 , 30 ) and paraffinizing devices ( 31 , 32 ) do not hinder the movement of the suction arms, because the suction arms of the thread return devices ( 58 , 59 ) unload so far that they can swing past the ends of the devices mentioned.

In the case of the different types and designs of the structural units ( 52 ) or ( 53 ), the coil drive devices ( 35 ) or ( 36 ) are arranged in such a way that they are driven by one and the same coupling means ( 64 ) or ( 65 ) with a drive motor ( 66 ) or ( 67 ) are connectable. Timing belts, for example, are to be used as coupling means here. The toothed belt ( 64 ) runs over a gearwheel ( 68 ) seated on the shaft of the motor ( 66 ) and over a gearwheel of the same size belonging to a gearbox ( 72 ) which drives the coil drive device ( 35 ) via the gearbox ( 72 ). The toothed belt ( 65 ) runs over a gearwheel ( 70 ) which sits on the shaft of the drive motor ( 67 ) and over another gearwheel ( 71 ) of the same size which sits directly on the shaft ( 73 ) of the coil drive device ( 36 ). The coupling means ( 64 ) or ( 65 ) are accessible from outside through windows ( 74 ) or ( 75 ) in the holding frame ( 50 ) or ( 51 ).

For example, if the units ( 52 ) and ( 53 ) ( Fig. 2, Fig. 3) are to be exchanged for one another, the toothed belts ( 64 ) and ( 65 ) ( Fig. 1) are first stripped to the right and then the holding frame ( 50 ) and ( 51 ) are pulled out of the dovetail guides ( 54 ) and ( 55 ). Then you have the units ( 52 ) and ( 53 ) in your hand and you can push them in reverse order of the handles into the other dovetail guide ( 54 ) or ( 55 ) and then put the timing belt back on. In their operating positions, the holding frames ( 50 ) or ( 51 ) can be locked or secured against the frames ( 23 ) or ( 24 ) by locking means, for example bolts.

Can see Fig. 2 and 3 that electrical for making interconnections to the frames (23) and (24) of the winding apparatus (6) and (7) plug-in connections in the form of bushings (76, 77) and (78, 79) provided are which match corresponding plug connections in the form of plug pins ( 80 , 81 ) or ( 82, 83 ) arranged on the holding frame ( 50 , 51 ) of the structural units ( 52 , 53 ). The plug connections are not required for the operation of the structural unit ( 53 ). In this case, you are blinded. The plug connections are required for operating the structural unit ( 52 ), in which the plug pins ( 80 ) and ( 81 ) are connected to the motor ( 45 ) in order to operate the oscillating thread guide ( 44 ).

Figs. 2 and 3 also indicate that are prepared on the racks (23) and (24) pneumatic plug connections (84, 85) and (86, 87) in order, if necessary, that is, at differently designed components and pneumatic interconnections to be able to manufacture. The counterparts of these connectors would then be in the dovetails of the holding frame.

Can see Fig. 2 and 3 that the parts of the assemblies (52) and (53), neither the walking movement can hinder even the operation of the operation unit (11). The package spool ejector ( 15 ) can, for example, pivot freely about its pivot point ( 88 ) in order to capture a fully wound package and roll over the rolling surface ( 17 ) and the rolling surface ( 16 ) onto the receiving trough ( 18 ), as indicated in the drawings.

In the selected exemplary embodiments, drive motors ( 66 ) and ( 67 ) are provided for operating the coil drive devices. Instead, a central drive motor can be present in one of the end frames, to which a transmission shaft is connected, to which in turn the coupling means can be connected.

In Fig. 1 the traversing triangle of the threads ( 46 ) and ( 47 ) is indicated by dash-dotted lines. The same Fig. 1 shows that the frames ( 23 ) and ( 24 ) have windows ( 89 ) and ( 90 ) which facilitate handling of the coupling means ( 64 ) and ( 65 ). Otherwise, the winding apparatuses ( 6 ) and ( 7 ) can also have further devices which facilitate spooling, but to which reference should not be made here.
