         [0001]    This application claims the benefit of German patent application DE P 199 62 295.7, filed Dec. 23, 1999, and German patent application DE. 1 P 100 44 632.9, filed Sep. 9, 2000, herein incorporated by reference.  
           [0002]    1. Field of the Invention  
           [0003]    The present invention relates to an interface for feeding fresh spinning cops into the transport system of a textile machine producing cross-wound bobbins, also referred to as cheeses.  
           [0004]    2. Background of the Invention  
           [0005]    Modern textile machines producing cross-wound bobbins, e.g., automatic cross-wound bobbin winders, generally comprise a plurality of similar winding heads as well as a transport system for supplying spinning cops and/or empty tubes to these winding heads and removing them from these heads. Transport pallets with vertically arranged receiving spindles or pins circulate within such a transport system comprising, as is known and described in, as well as elsewhere, German Patent Publication DE 43 39 964 A1, several different transport conveyors. Either spinning cops or empty tubes are transported on these transport pallets. Moreover, processing stations for the spinning cops and/or for the empty tubes, such as, e.g., cop preparation stations, tube monitors, tubes cleaning devices, etc., are customarily arranged at locations along such a transport system.  
           [0006]    The transport system of an automatic cross-wound bobbin winder can either be directly connected via a so-called changeover device to the transport system of an associated textile machine connected upstream of the winder transport system, typically a spinning machine for producing spinning cops, which instance is referred to as a compound textile machine, or the transport system of the automatic cross-wound bobbin winder is supplied via a special interface with spinning cops of a separately arranged free-standing ring spinning machine, as indicated in European Patent Publication EP 0 534 229 B1. In this instance an appropriate interface for removing the empty unwound tubes is also provided.  
           [0007]    An interface for feeding fresh spinning cops comprises, e.g., a cop mounting and centering device arranged in the area of a receiving conveyor which device is normally preceded by a circular flat transporter. Cop mounting and centering devices and circular flat transporters are basically known, e.g., from German Patent Publications DE 33 48 033 C2 or DE 41 12 434 A1.  
           [0008]    In order to assure that the spinning cops are held securely on the transport pallets in subsequent work processes it is also known that the receiving spindles of these transport pallets can be provided with tensioning means onto which the fresh spinning cops are impressed by a special impressing device after the mounting and centering onto the transport pallets. A device consisting of a cop mounting and centering device and of a following impressing device and arranged at a receiving conveyor is shown and described, e.g., in German Patent Publication DE 40 16 466 A1.  
           [0009]    However, these known devices have the disadvantage that they are relatively expensive to construct. The known devices have, e.g., at least two separate drives. A first drive loads a mounting and centering device as well as a following impressing device via a cam disk packet whereas a second motor is connected to a circulating conveyor belt arranged in the area of the receiving conveyor, which conveyor belt transports the transport pallets loaded with spinning cops.  
         SUMMARY OF THE INVENTION  
         [0010]    The present invention accordingly has a basic objective to improve upon the state of the art discussed above, and more particularly to create an interface for feeding fresh spinning cops into the transport system of a textile winding machine producing cross-wound bobbins which interface is simplified with respect to its drives.  
           [0011]    The invention addresses this problem by providing an improved interface for a transport system of a textile winding machine which has a receiving conveyor for feeding thereonto of spinning cops, a centering device in the area of the receiving conveyor for setting spinning cops onto receiving spindles of transport pallets circulating in the transport system and a downstream impressing device for fixing the spinning cops on the receiving spindles. According to the present invention, the interface comprises a drive arranged in the area of the receiving conveyor for driving transportation of the transport pallets along the receiving conveyor and for actuating the centering device.  
           [0012]    The embodiment in accordance with the invention has the particular advantage that the transportation of the spinning cops in the receiving conveyor and also the mounting and centering of the spinning cops onto the receiving spindles of the transport pallets now take place in an economical manner by means of a single drive.  
           [0013]    In an advantageous embodiment, a transport disk is arranged on the input side of the receiving conveyor which disk comprises at least two transport pockets for transporting transport pallets. Such transport disks are distinguished by a long service life and a simple design. The transport pockets arranged in a predetermined angular interval assure a completely uniform, cyclic transport of the transport pallets on the receiving conveyor. That is, the transport pallets are transported further in an indexable fashion by a certain, always uniform path upon each actuation of the transport disk and the transport pallets are thereby positioned exactly in the range of the centering device as well as of a tube impressing device arranged in the vicinity.  
           [0014]    A preferred embodiment also provides that even the following tube impressing device is connected via an appropriate transmission arrangement to the transport disk. That is, in such a design the transportation of the transport pallets, the insertion and centering of the fresh spinning cops on these transport pallets as well as the subsequent impressing of the spinning cops onto the receiving spindles of the transport pallets take place by means of a single drive.  
           [0015]    In an advantageous embodiment, the transmission arrangement comprises an eccentric element rotating with the transport disk, with a two-armed lever in following relation on this eccentric which lever is connected via a draw rod to a vertical linkage of the tube impressing device. Frictional losses like those that always occur in a mechanical transfer of power can be minimized by such a relatively direct coupling of transport disk and tube impressing device, which decreases the load from the transport disk drive.  
           [0016]    The centering device may be mechanically coupled to the adjacent tube impressing device. Such a mechanical coupling assures in a simple manner that each spinning cop is positioned in the prescribed manner on an associated transport pallet and fixed in an orderly manner on the receiving spindle of the transport pallet.  
           [0017]    A preferred embodiment provides that the centering device and the impressing device are connected via a lever arrangement. Such a coupling is not only extremely robust and insensitive but can also be serviced and/or repaired without significant expense by the service personnel if required.  
           [0018]    In an advantageous embodiment at least two sensor devices, preferably Hall sensors, are installed in the area of the transport disk, which sensors are loaded by corresponding ferromagnetic components of the transport pallet or of the transport disk.  
           [0019]    The first sensor device reacts to control bores in the metallic transport disk that are arranged in such a manner that the Hall sensor of the first sensor device is non-loaded only at the correct alignment of the transport disk. The second Hall sensor is loaded when a new transport pallet, that comprises a steel ring, e.g., in the area of its standing foot, has been received in a transport pocket of the transport disk disposed at the ready in a receiving position. A signal of this second sensor device results, in conjunction with a corresponding release signal of a light barrier arranged in the area of the centering device, in the execution by the transport disk of a working stroke.  
           [0020]    The transport disk is driven in a preferred embodiment by an electromotor that can be controlled in a defined manner, preferably by means of a stepping motor. Such stepping motors are not only relatively inexpensive but can also be positioned without significant measures.  
           [0021]    In a preferred embodiment at least one switching means connected to the centering device and to the impressing device is arranged in the area of the receiving conveyor which switching means extends into the transport path. The transport pallets transported by the transport disk on the receiving conveyor in the direction of transport pivot the switching means outward at each transport stroke, which results at first in an opening actuation of the centering device.  
           [0022]    Preferably, the switching means advantageously comprises two switching devices in the form of opener stars. As already indicated above, the opener stars are positioned in the non-loaded state in the area of the transport path of the transport pallets and are pivoted outward by the transport pallets during their further transport.  
           [0023]    The opener stars are arranged on bearing shafts in such a manner as to rotate in unison therewith such that their pivoting motion is transferred via actuating elements to a lever arrangement which is connected to the impressing device. Thus, the pushing force introduced from the drive motor of the transport disk onto the transport pallets acts via the opener stars and the associated lever arrangement not only to transport the transport pallets on the receiving conveyor but serves at the same time to control the centering device and also to open the impressing device.  
           [0024]    In a preferred design, the lever arrangement includes actuating wires extending into the transport path of the transport pallets on the receiving conveyor and a vertically arranged linkage connected to a bearing arrangement having at least one tube impressing shell arranged thereon. Such an embodiment is not only very robust and insensitive but can, as already indicated above, also be readily serviced or repaired by the service personnel if required.  
           [0025]    It is particularly advantageous that the bearing arrangement comprises a parallelogram guide rod arrangement to which the tube impressing device is connected. The parallelogram guide rod arrangement comprises for its part at least one tube impressing shell. However, in a further development of the invention, an embodiment can also be advantageous in which two tube impression shells are provided at different heights and successively in the direction of transport of the transport pallets.  
           [0026]    The parallelogram guide rod arrangement can be raised above the lever arrangement and is loaded by at least one spring element for urging the impressing shells in a direction toward the receiving conveyor into a tube impressing disposition. Such a design advantageously assures not only a uniform impression force of the tube impressing shells, so that it is assured that the spinning cops are always thrust completely over spring baskets of the receiving spindles of the transport pallets but it also reliably avoids damaging of the tubes during the impressing process by too great an impression force.  
           [0027]    Further details of the invention can be gathered from an exemplary embodiment explained in the following disclosure with reference made to the drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0037]    Referring now to the accompanying drawings and initially to FIG. 1, a transport system  21  of an automatic cross-wound bobbin winder (not shown in detail) is schematically indicated. Transport system  21  comprises interface  22  for feeding spinning cops  19  that were manufactured on a separate, free-standing ring spinning machine and further comprises an appropriate interface for removing empty tubes, e.g., tube withdrawal device  23 .  
         [0038]    Such known transport systems  21  comprise a plurality of different transport conveyors via which winding heads  24  of the automatic cross-wound bobbin winder are supplied with spinning cops  19  and via which empty tubes  18  are removed from the winding heads.  
         [0039]    As is known, a cop supply conveyor  2  follows a receiving conveyor  1  in such transport systems from which cop supply conveyor branch preparation conveyors  3 . Preparation conveyors  3  are connected via transport removal conveyors  4  to storage conveyor  5  that, in turn, communicates with tube return conveyor  8  via numerous transport conveyors  6  running through respective winding heads  24  transversely between storage conveyor  5  and tube return conveyor  8 . Tube return conveyor  8  is followed by distributor conveyor  9  that empties into receiving conveyor  1 . In addition, tube return conveyor  8  is connected via connecting conveyor  7  directly to cop supply conveyor  2 .  
         [0040]    A so-called transversal passage  10  extending between distributor conveyor  9  and cop supply conveyor  2  branches off from distributor conveyor  9 , on which one tube monitor  15  is usually arranged. Tube cleaner conveyor  11  with tube cleaner  16  arranged thereat is connected to the transversal passage  10 . In addition, a manual preparation conveyor  12  can branch off from tube cleaner conveyor  11 .  
         [0041]    During a winding operation, numerous transport pallets  17  circulate within transport system  21  in direction of transport T, which plates are provided either with spinning cops  19  or with empty tubes  18 . Transport pallets  17  are briefly empty only in the area between empty tube withdrawal device  23  and centering device  33  of interface  22 .  
         [0042]    As FIG. 1 schematically indicates, a so-called cop preparation station  13  is installed in the area of preparation conveyors  3  in which station spinning cops  19  are prepared in such a manner that they can be rewound subsequently at winding heads  24  to large-volume cross-wound bobbins. The transportation of transport pallets within transport system  21  takes place, with the exception of receiving conveyor  1 , via rotating endless conveyor belts  14 , preferably flat belts.  
         [0043]    As will be explained in detail hereinafter, transport pallets  17  are nevertheless not transported by conveyor belt  14  in the area of receiving conveyor  1  but rather by transport disk  25  that can be controlled in a defined manner. Transport disk  25  rotates in a manner that can be cyclically controlled and thereby pushes transport pallets  17  in a controlled manner over receiving conveyor  1 .  
         [0044]    As FIG. 1 furthermore shows, interface  22  for feeding fresh spinning cops  19  is installed in the area of receiving conveyor  1 . Interface  22  comprises centering device  33  as well as tube impressing device  26  mechanically coupled to centering device  33 . Moreover, centering device  33  is connected to circular flat transporter  20 .  
         [0045]    [0045]FIGS. 2 and 8 show alternative embodiments of the interface of the present invention. In each case, a transport disk  25  is arranged in the entrance area of receiving conveyor  1 . This transport disk comprises either three transport pockets  34  staggered by 120° or, as shown in FIG. 8, two transport pockets  34  staggered by 180°. Moreover, transport disk  25  comprises control bores  35 ′,  35 ″,  35 ′″, as shown in FIG. 2, located in correspondence with compatibly designed sensor devices  29 ,  31 .  
         [0046]    These sensor devices  29 ,  31  are advantageously Hall sensors that can be loaded ferromagnetically, and are connected along with light barrier  30 ,  63  positioned in the area of centering device  33  to control device  28 , that also controls the drive of transport disk  25 , which drive is preferably in the form of electromotor  27 .  
         [0047]    Moreover, as is further apparent from FIGS. 2 and 8 two pivotably mounted switching means, preferably in the form of so-called opener stars  36 ,  36 ′, are arranged in the area of receiving conveyor  1 . Opener stars  36 ,  36 ′ are connected via levers  37 ,  37 ′ to rotatably mounted bearing shaft  38 ,  38 ′ in such a manner that they rotate in unison with it.  
         [0048]    As FIGS. 3 and 4 show in particular, loading shaft flaps  39  and  39 ′ as well as actuating elements  40  and  40 ′ or, as in the exemplary embodiment of FIG. 8, solely loading shaft flaps  39 ,  39 ′, are articulated to bearing shafts  38 ,  38 ′, likewise in such a manner that they rotate in unison with them. Actuating elements  40  and  40 ′ according to FIGS. 3 and 4 are connected in turn to pivot lever  41  mounted such that it can rotate in a limited manner by means of pivot shaft  42 . Actuating wires  46  are arranged on pivot shaft  42  and extend into the area of the transport tracks of transport pallets  17 .  
         [0049]    Moreover, pivot lever  41  is connected via connecting link  43  to angle lever  45  mounted so that it can rotate about shaft  44 . Substantially vertically arranged linkage  47  follows angle lever  45  and is connected to support arrangement  48 . The support arrangement can be designed as parallelogram guide rod arrangement  48 , as shown in FIG. 3, that is loaded by at least one spring element  49  to urge the arrangement  48  downwardly for impressing tubes onto transport pallets  17  as more fully explained hereinafter. In a further aspect of the invention, such a parallelogram guide rod arrangement  48  can also comprise two impressing shells  50  and  51  positioned at different levels as shown in FIG. 3.  
         [0050]    [0050]FIG. 4 schematically shows a top view of lever arrangement  64  that was described above with respect to the side view of FIG. 3, and connects centering device  33  to tube impressing device  26 . As already explained above, loading shaft flaps  39  and  39 ′, opener stars  36  and  36 ′ as well as actuating elements  40  and  40 ′ are connected to pivotably mounted bearing shafts  38  and  38 ′ via corresponding levers. Actuating elements  40 , 40 ′ are connected in turn to pivot lever  41  mounted so that it can rotate in a limited manner via pivot shaft  42  and coupled to connecting link  43 . Moreover, actuating wires  46  are fixed to pivot shaft  42  and extend, as previously described, into the transport path of transport pallets  17 . Connecting link  43  loads angle lever  45 , that can pivot about shaft  44  and is connected to vertically arranged linkage  47  of tube impressing device  26 .  
         [0051]    [0051]FIGS. 5 a  and  5   b  show loading shaft flaps  39  of centering device  33  in section. As indicated, centering aids  52  that can be continuously adjusted to different cop diameters are arranged within loading shaft flaps  39  and  39 ′.  
         [0052]    [0052]FIGS. 6 and 7 show spinning cop alignment device  66  arranged in the area of interface  22  and connected between centering device  33  and circular flat transporter  20 . Such known spinning cop alignment devices  66  consist substantially of a supply shaft  53  connected to circular flat transporter  20 , support  54  and magazine wheel  55  with receiving pockets  56 . Support strips  57  with diverters  58  as well as cop funnel  59  follow magazine wheel  55 . Moreover, sensor element  60 , preferably in the form of a light scanner or light barrier, is installed in the area of support  54 .  
         [0053]    A further preferred embodiment of the invention is shown in FIGS. 8 and 9. This advantageous embodiment differs from the previously described device primarily by the manner of control of tube impressing device  26 . As FIG. 8 indicates, transport disk  25 , can be loaded via electromotor  27  and is directly connected to tube impressing device  26  (not shown in FIG. 8) via transmission arrangement  70 . Transmission arrangement  70  comprises essentially eccentric cam element  71  arranged on transport disk  25  in such a manner that it rotates in unison with disk  25 , two-armed lever  72  resting on eccentric cam element  71  and draw rod  73 .  
         [0054]    As is known from the previously described exemplary embodiment of FIG. 3, draw rod  73  is connected, via angle lever  45  that is pivotably mounted in shaft  44 , to vertically arranged linkage  47  of tube impressing device  26 . At least one impressing shell  50  is first raised above linkage  47  and subsequently lowered under the biasing force of spring power onto the tube tip of spinning cop  19  in this embodiment also.  
         [0055]    The operation of the present invention may thus be understood with reference to the exemplary embodiment according to FIG. 3. Empty tubes  18  whose yarn has been unwound and rewound at winding heads  24  travel in upstanding disposition on transport pallets  17  via tube return conveyor  8  onto distributor conveyor  9  and are removed thereat from the transport pallets  17  by tube withdrawal device  23 . Transport pallets  17 , which are then empty, are transported via distributor conveyor  9  into the range of transport disk  25  disposed in a ready position to receive empty transport pallets  17 . A single transport pallet  17  thereby moves into one of transport pockets  34  of transport disk  25 . The transport pallet  17  is at least partially ferromagnetic and thereby loads Hall sensor  29  arranged in this area. The signal of Hall sensor  29  is processed in control device  28  to control electromotor  27  such that, if an appropriate release signal of light barrier  30 ,  26  is present, transport disk  25  rotates in direction R. Transport disk  25  is rotated until Hall sensor  31  switches into an unloaded state, e.g., on account of control bore  35 ″ in transport disk  25 . Thus, in the present exemplary embodiment of FIG. 2, transport disk  25  is indexed by 120 degrees for each transport pallet  17  received. Transport disk  25  thereby positions the transport pallet  17  at the entrance of the receiving conveyor  1  and moves transport pallets  17  already on receiving conveyor  1  in the direction of centering device  33  as well as of impressing device  26 .  
         [0056]    At the same time a fresh spinning cop  19  is made available via spinning cop alignment device  66  (shown in FIGS. 6 and 7) on centering device  33 . Specifically, spinning cop alignment device  66  is provided with a fresh spinning cop  19  via known circular flat transporter  20 , which cop slides via supply shaft  53  onto support  54  of spinning cop alignment device  66  and is braked on buffer  62 . Spinning cop  19  rests on support  54  thereby in any desired tip alignment. Spinning cop  19  is subsequently transported further in an indexable manner by magazine wheel  55 , comprising, e.g., six receiving pockets  56  arranged at an interval of 60°, and is transferred onto support strips  57 .  
         [0057]    As soon as sensor  60  installed in the area of support  54  determines that a spinning cop  19  is no longer present on support  54 , another spinning cop  19  is supplied via supply shaft  53 . Moreover, sensor device  30 ,  63  arranged in the area of receiving conveyor  1  detects whether a spinning cop  19  is positioned below loading shaft flaps  39 ,  39 ′ of centering device  33  on a transport pallet  17  or whether an empty transport pallet is available thereat for receiving a fresh spinning cop  19 . If this is the case, magazine wheel  55  is indexed further by 60 degrees and the spinning cop  19  present on receiving strips  57  is transported in direction V (FIG. 7) to cop funnel  59 .  
         [0058]    Moreover, since diverters  58  are installed above support strips  57  at an interval somewhat greater than the diameter of the tube tip, spinning cop  19  glides during this transport on support strips  57  with its tube tip between support strips  57  and diverters  58  while the tube foot, which is greater in diameter, is pressed away from diverters  58 . Diverters  58  shift spinning cop  19  thereby on support strips  57  in the direction of the tube tip such that the tube foot looses its support and spinning cop  19  falls, as shown in FIG. 6, with the tube foot leading downwardly into cop funnel  59 . Spinning cop  19  passes via cop funnel  49  between closed loading shaft flaps  39 ,  39 ′ of centering device  33  and falls under the alignment of centering aids  52  over receiving spindle  65  of transport pallet  17  positioned thereat.  
         [0059]    Sensor device  30 ,  63  arranged in the area of centering device  33  detects this spinning cop  19  and transmits a corresponding signal to control device  28 . If a signal of Hall sensor  29  loaded by transport pallets  17  is also present at that time in control device  28 , transport disk  25  is indexed further by one spacing, which results in a transport step of transport pallets  17  located on receiving conveyor  1 . That is, all transport pallets  17  standing on receiving conveyor  1 , whether empty or provided with a spinning cop  19 , are shifted on receiving conveyor I by one transport pallet diameter in direction T.  
         [0060]    As indicated in FIG. 2, the transport pallet  17 ′ immediately in front of opener stars  36 ,  36 ′ thereby pivots opener stars  36 ,  36 ′ outwardly in direction S. Since the opener stars  36 ,  36 ′ are connected via levers  37  and  37 ′ to bearing shafts  38  and  38 ′ and shaft flaps  39 ,  39 ′ are likewise connected via corresponding levers to bearing shaft  38  to rotate in unison therewith as aforedescribed, this pivoting motion of opener stars  36 ,  36 ′ pivots shaft flaps  39 ,  39 ′ outwardly so that the particular transport pallet  17  with spinning cop  19  can leave centering device  33 .  
         [0061]    Moreover, actuating elements  40 ,  40 ′ are connected to bearing shafts  38  in such a manner that they can rotate in unison with them, likewise via corresponding levers. These actuating elements are shifted forward by the pivoting motion S introduced via the opener stars  36 ,  36 ′, as indicated in FIG. 3, and this forward movement VB is transferred to pivot lever  41 , that can pivot about pivot shaft  42 . Actuating wires  46  are also connected to pivot lever  41  and pivot shaft  42  in such a manner that they can rotate in unison with them. These actuating wires are pressed downward during transport on receiving conveyor  1  by a transport pallet  17  standing with a spinning cop  19  supported thereon, e.g., in the area of centering device  33 . Even this pivoting movement U is transferred via pivot lever  41  to connecting link  43 . In turn, connecting link  43  loads angle lever  45 , mounted so that it can rotate about shaft  44 . The forward movement is converted by angle lever  45  into a lifting movement that is transferred via linkage  47  to bearing arrangement  48  of tube impressing device  26 .  
         [0062]    More specifically, bearing arrangement  48  comprises e.g., a parallelogram guide rod arrangement which is pivoted in direction H by linkage  47  against the force of spring element  49  that acts on bearing arrangement  48 . Impressing shells  50 ,  51  arranged on the parallelogram guide rods of the bearing arrangement  48 , are thereby raised to such an extent that spinning cops  19  standing under them are freed and can also be shifted further by one stroke in direction T.  
         [0063]    At the end of each shifting stroke, actuating wires  46  extending out laterally into the transport path of transport pallets  17  lose all contact with the transport pallets located on receiving conveyor  1 . Parallelogram guide rod arrangement  48 , that had been held prior to this point by actuating wires  46  in a raised position, is now lowered by spring element  49  and presses spinning cops  19  thereby with impressing shells  50 ,  51  onto receiving spindles  65  of transport pallets  17 . In the exemplary example shown, the impressing of spinning cops  19  onto receiving spindles  65  of transport pallets  17 , which spindles are generally provided with a spring basket or the like, takes place in two stages.  
         [0064]    As already indicated above, the invention is not limited to the described exemplary embodiment, and specifically is not limited to a two-stage impressing process. It is understood that the apparatus in accordance with the invention can also operate in a one-stage manner after the appropriate modification shown in FIG. 8. That is, the spinning cops can also be loaded by a tube impressing device comprising only one impressing shell.  
         [0065]    It will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to its preferred embodiment, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof
