DETAILED DESCRIPTION

[0044] FIG. 1 shows a winding machine 1. The winding machine 1 has a drive, here an electrical drive 2 which is held on a machine frame 3 of the winding machine 1. A drive wheel 4 driven by the drive 2 is in drive connection with an output-side drive wheel 6 via a traction mechanism 5 such as a toothed belt or a linkage. The output-side drive wheel 6 is rotationally fixedly coupled with a spindle 8, here via a key 7. By actuating the drive 2, with a transmission of gears up or down depending on the transmission ratio between the input-side drive wheel 4 and the output-side drive wheel 6 a rotational motion 9 of the spindle 8 can be induced.

[0045] The spindle 8 via a spindle bearing 10 is supported rotatably around a longitudinal and rotational axis 11 on the machine frame 3. The spindle bearing 10 forms a so-called overhung bearing. The spindle bearing 10 is arranged on one side of the machine frame 3 while the freely extending partial region of the spindle 8 in which the spool 12 is wound is arranged on the other side of the machine frame 3.

[0046] The spindle 8 is realised as a hollow shaft 13 with a continuous inner bore or recess 14. Through the inner recess 14 of the spindle 8 an actuation rod 15 extends. The end region of the actuation rod 15 extending from the spindle bearing 10 is connected with an actuator 16, which here is a linear drive 17. In the other end region which extends from the spindle 8, the actuation rod 15 via a coupling device 19 is coupled to the traversing carriage 20. By means of the actuator 16, the actuation rod 15 can be moved backwards and forwards coaxially to the rotational axis 11, in which way the actuation rod 15 executes a traversing motion 18.

[0047] Here, the traversing carriage 20 is realised with a traversing sleeve 21 which for the embodiment shown is realised integrally with a clamping sleeve 22. The coupling device 19 enables a transmission of axial forces so that via the coupling device 19 the traversing motion 18 is transmitted from the actuation rod 15 onto the traversing carriage 20. The coupling device 19, on the other hand, for the embodiment shown enables a relative rotation of the traversing carriage 20 with respect to the actuation rod 15. As will be explained in more detail in the following, in this way the traversing carriage 20 can perform the rotational motion 9 caused by the drive 2 with the spindle 8, while the actuation rod 15 does not execute a rotational motion 9, which simplifies a coupling of the actuation rod 15 with the actuator 16. (It is possible, however, that the coupling device 19 is not realised with such a relative rotational degree of freedom. In this case, the actuation rod 15 rotates with the traversing carriage 20 while a rotational degree of freedom can be provided in another place, especially in the coupling region of the actuation rod 15 to the actuator 16.)

[0048] The traversing carriage 20 is axially slidably but rotationally fixedly guided on the spindle 8. For the embodiment shown, the traversing sleeve 21 with which the traversing carriage 20 is formed in order to achieve this has an opening in which a catch 23 is fixed which for the embodiment shown is achieved by end-sided bolting. The catch 23 and the traversing sleeve 11 (including the bolting) form a plane cylindrical surface area. The catch 23 forms a rib extending with respect to the inner surface of the traversing sleeve 21 or a protrusion 24 which engages with an opening 25 or groove of the surface area of the spindle 8. By the engagement of the protrusion 24 of the catch 23 with the opening 25 of the spindle 8, a form-locking in the circumferential direction is created so that the rotational motion 9 is transmitted from the spindle 8 via the side boundaries of the opening 25, the protrusion 24, the catch 23 onto the traversing sleeve 21 and therefore the traversing carriage 20. The opening 25 is realised with a larger axial extension in the way of an elongated groove or an elongated hole so that the protrusion 24 can move in the opening 25 in the axial direction without eliminating the form-locking in the circumferential direction. This degree of freedom of motion of the protrusion 24 in the opening 25 is dimensioned at least so large that the protrusion 24 and therefore the traversing sleeve 21 and the traversing carriage 20 with respect to the spindle 8 can execute the traversing motion 18 at simultaneous taking along of the traversing carriage 20 by the spindle 8 with respect to the rotational motion 9.

[0049] Via a coupling device or spool sleeve clamping device 26, on the traversing carriage 20, here on the traversing sleeve 21, a spool sleeve 27 is held in such a way that the spool sleeve 27 executes [0050] the traversing motion 18 of the traversing carriage 20 created by the actuator 16 and transmitted via the actuation rod 15 and the coupling device 19 and [0051] the rotational motion 9 created by the drive 2 and transmitted from the spindle 8 via the catch 23 to the traversing carriage 20.

[0052] On the spool sleeve 27 in a way that is known as such a winding 28 of the spool 12 is formed while overlaying the rotational motion 9 and the traversing motion 18. The traversing motion 18 of the traversing carriage 20 leads to an axial relative motion between the traversing carriage 20 and the spindle 8 which is guided by the guiding units 29a, 29b, especially slide bearings, which are arranged between the inner surface of the traversing sleeve 21 and the surface area of the spindle 8. In the embodiment shown, the guiding units 29a, 29b are arranged on both sides of the catch 23. Between the actuator 16 and the traversing carriage 20 an actuation mechanism 30 is interposed, which transmits the traversing motion 18 to the traversing carriage 20 or causes it. For the embodiment shown, the actuation mechanism 30 is formed with the actuation rod 15 and the coupling device 19. For this actuation mechanism 30, by means of the actuation rod 15 the traversing motion 18 is completely led through the spindle 8 realised as a hollow shaft 13, led radially outside in the region of the coupling device 19 and then radially on the outside is led back from the surface area of the spindle 8. In a semi-longitudinal section therefore a flow of power results that corresponds to a lying U, where the coupling device forms the base arm of the U, while the actuation rod forms the radially inner side arm of the U and the other parallel and radially outer side arm of the U is formed by the traversing carriage 20. This U-shaped flow of power with the two side arms surrounds the freely extending end portion of the spindle realised as a hollow shaft 13 in this semi-longitudinal section.

[0053] The winding machine 1 has a control unit 31. The electrical lines 32 to 35 connected with this are shown in FIG. 1 with dash-dotted lines. Via the line 32, the control unit 31 controls the drive 2 for inducing the desired course of the rotational motion 9. For guaranteeing a closed-loop control, the control unit 31 via the line 33 is fed a rotational speed signal of the drive 2. Furthermore, the power provision and control of the linear drive 17 is achieved via the control unit 31 via the line 34, where here for enabling a closed-loop control of the control unit 31 via the line 35 a rotational speed signal can be fed.

[0054] In the detail II according to FIG. 2, the spindle bearing 10 is formed with a sleeve-like bearing body 36 which is supported by the machine frame 3. On the sleeve-like bearing body 36, on the inner side bearing units 37a, 37b are braced via which in a way that is known as such the spindle 8 is supported with respect to the bearing body 36.

[0055] On the side turned towards the spool 12, on the machine frame 3 an actuation body 38 is held which forms an actuation surface 39 or a conical actuation surface 70 inclined with respect to the rotational axis 11. The actuation surface 39 or conical actuation surface 70 in a way that will be explained in detail in the following comes into interaction with an inclined surface 40 or a conical inclined surface 69 of the traversing carriage 20, the traversing sleeve 22 and the clamping sleeve 22 which is inclined correspondingly with respect to the rotational axis 11 and is arranged in the end region of the machine frame 3 turned towards the machine frame 3.

[0056] In FIG. 2 it is furthermore to be seen that the traversing carriage 20 is sealed with respect to the spindle 8 via a sealing unit 68 in the end region turned towards the machine frame 3.

[0057] FIG. 4 shows the detail IV with a coupling device 19. The coupling device 19 has a lid 41. The lid 41 has two parallel, sleeve-like protrusions 42, 43. The outer protrusion 42 is screwed into an end-side inner thread of the traversing carriage 20 or the traversing sleeve 21 or clamping sleeve 22 with an outer thread. The protrusion 42 has an inner diameter which is larger than the outer diameter of the spindle 8. The sleeve-like protrusion 43 with its inner surface 44 forms a support surface for bearing units 45a, 45b. On the bearing units 45a, 45b on the radial inner side the assigned end region of the actuation rod 15 is supported. The bearings 45a, 45b in a way that is known as such, here via ledges, securing nuts and a securing ring, are axially secured with respect to the lid 41 on the one hand and with respect to the actuation rod 15 on the other hand. The bearing units 45a, 45b form an axial support 46, by means of which the traversing motion 18 is transmittable from the actuation rod 15 onto the traversing carriage 20. In the ring space formed between the sleeve-like protrusions 42, 43 in the position shown in FIG. 4, the end region of the spindle 8 here formed with steps can be arranged. For the embodiment shown, the lid 41 is realised with a through-bore via which the mounting and the tightening of the shaft nuts is enabled. In a way that is not shown, the coupling devices 19 and the lid 41 can each be closed with a closing element closing the through bore of the lid 41, so that as a whole the traversing carriage 20 and the coupling device 19 in the end region shown in FIG. 4 are closed and capsuled, so that no dirt created during the spooling process can enter into the interior where they could for example impede the function of the bearing units 45a, 45c.

[0058] In FIG. 5, the actuator 16 realised as a linear drive 17 is shown in a larger detail V. The drive drives a belt pulley of the belt drive 47 back and forth. On the belt of the belt drive 47, a catch 48 is fixed which in turn is fixed to the end region of the actuation rod 15. In this way, the actuation of the actuator 16 with a motion back and forth of the belt drive 47 leads to the motion of the actuation rod 15 with the traversing motion 18.

[0059] The functioning of the winding machine according to FIGS. 1 to 6 is as follows:

[0060] To begin, with a spool sleeve 27 is pushed onto an empty spindle 8 and an empty traversing carriage 20 until it comes to rest on the front face against a rest 49. The rest 49 here is formed by a surrounding flange or collar 50 of the traversing carriage 20, the traversing sleeve 21 or the clamping sleeve 22, where the collar 50 on the side turned towards the machine frame 3 also forms the inclined surface 40 or the conical inclined surface 69.

[0061] Subsequently, the spool sleeve clamping device 26 is actuated, in which way a fixing of the spool sleeve 27 to the traversing carriage 20 is achieved which is rotationally fixed as well as secured axially.

[0062] Next, a winding good 51 is led towards the spool sleeve 27 in such a way that a winding is established. A catching device for the winding material 51 in the region of the winding machine 1 or the spool sleeve 27 can be provided that is known in itself. During the winding cycle then induced, the control unit 31 controls the drive 2 and the actuator 16 in a coordinated way so that in the creation of the winding 28 overlaying the traversing motion 18 and the rotational motion 9 a desired winding appearance is caused. FIG. 1 and FIG. 6 show the traversing carriage 20 and the spool 12 arranged on it in both end points of the traversing motion 18, that is, FIG. 1 a back end position with the smallest distance from the machine frame 3 and FIG. 6 a front end position with maximum distance from the machine frame 3. Between these end positions, with the traversing motion the motion of the traversing carriage 20 with the spool 12 arranged on it occurs in such a way that a winding good 51 is always fed from the same place without the necessity of the use of a traversing device with a traversing thread guide, where in an ideal case there is always a feeding of the winding good 51 perpendicular to the rotational axis 11.

[0063] At finishing the winding 28, the spool sleeve clamping device 26 is released so that removal of the completely wound spool 12 from the traversing carriage 20 is possible. In a way known as such, at first a clipping of the winding good can occur. It is possible that the control unit 31 is equipped with a control logic by means of which purposely there can be a feeding of the winding good by a corresponding motion of the traversing carriage 20 to a catching device and/or a cutting device. This preferably occurs in a motional region of the actuator 16 which is not inside the usual stroke of the traversing motion 18 but outside it.

[0064] For the embodiment shown, the control unit 31 is equipped with control logic in such a way that the actuation of the spool sleeve clamping device 26 is achieved in a motion-controlled way via controlling the actuator 16, in order to do which the actuator 16 is controlled into a position which is outside the usual actuation path for the traversing motion 18. In this actuation position, for creating an actuation force via the actuator 16, the inclined surface 40 of the traversing carriage 20 is pressed against the actuation surface 39 fixed to the machine frame 3. Without creating this actuation force, the spool sleeve clamping device 26 is actuated in such a way that the spool sleeve 27 is held fixedly to the traversing carriage 20, while with creating the actuation force, the spool sleeve clamping device 26 is deactivated so that the spool sleeve 27 can be pushed slidably onto the traversing carriage 20 or be removed from it.

[0065] For creating the traversing motion 18 (with apart from that corresponding realisation of the winding machine 1), any actuator 16 can be employed. For the embodiment shown in FIG. 7, an electrical drive 52 is employed the drive wheel 53 of which via a traction mechanism 54 drives an output-side drive wheel 55 which is supported rotatably but axially fixed on a bearing body 36. The output-side drive wheel 55 forms a spindle nut 56 which with the spindle 57 forms a spindle drive 58. For the embodiment shown, the spindle 57 is formed with the side end region of the actuation rod 15 which in order to achieve this is equipped with an outer thread with which the spindle nut 57 is screwed. The motion of the spindle nut 56 caused by the drive 52 therefore results in the axial motion of the spindle 57 and therefore of the actuation rod 15, so that via the control of the drive 52 the traversing motion 18 can be caused.

[0066] FIG. 8 shows a further possibility for the realisation of the actuator 16. An electrical drive 59 drives a traverse cam 60 where a gliding element supported by the screw thread drive catch or traverse cam catch 48 engages with the reverse threading 61 of the traverse cam 60, in which way a self reversing screw drive 62 for causing the traversing motion 18 is formed.

[0067] Within the framework of the invention, any spool sleeve clamping device 26 can be employed. For the spool sleeve clamping device 26 in an exemplary way used in the previous figures, the traversing carriage 20, here the traversing sleeve 21, is realised as a clamping sleeve 22 which as a single part is shown in FIG. 9. The clamping sleeve 22 in an end region forms the collar 50 which forms the inclined surface 40 or the conical inclined surface 69 and the rest 49. In order to simplify it, further details of the clamping sleeve 22 and the opening for the catch 23, fixing bores for the bolting of the catch 23 to the clamping sleeve 22 and similar are not shown.

[0068] In FIG. 9 it can be seen that the clamping sleeve 22 is realised with a slit 63. While generally the slit 63 can be arranged in any axial region of the clamping sleeve 22 as far as this axial region has an overlap with the region in which the spooling sleeve 27 is to be clamped and the slit 63 can have any shape with a constant or varying width and any contour, according to FIG. 9 a clamping sleeve 22 is employed with a slit 63 inserted from the side of the machine frame 3 on the front face. The slit 63 has a first portion 64 which is oriented in parallel to the longitudinal or rotational axis 11 and a second portion 65 which extends in the circumferential direction from the inner end region of the portion 64 so that the two portions 64, 65 are arranged L-shaped in a flat projection. The slit 63 in the region of the portions 64, 65 has a constant and continuous width. With the slit 63 a weakening of the material of the clamping sleeve 22 is provided, so that the clamping sleeve 22 in the surrounding region of the slit 63 forms a deformation portion 74 which can be deformed with a smaller actuation force than this would be the case in another axial portion of the clamping sleeve 22. If, as has been explained before, for the actuation of the spool sleeve clamping device 26 the inclined surface 40 touches the actuation surface 39 of the actuation body 38, on the inclined surface 40 of the clamping sleeve 22 an actuation force is caused which presses the collar 50 radially inside. Through this, there is an elastic deformation of the clamping sleeve 22 with a reduction of the diameter of the surface area 66. With creating the actuation force which is induced by the actuator 16, the clamping sleeve 22 is brought into an elastically deformed state in which the diameter of the surface area 66 of the clamping sleeve 22 is marginally smaller than the diameter of the inner surface 67 of the spool sleeve 27 so that in this actuated state the spool sleeve 27 can be pushed onto the clamping sleeve 22 or (with the completely wound spool 12) can be removed from it. If, on the contrary, the actuator 16 is actuated in such a way that the collar 50 moves away from the actuation body 38, the actuation force is removed and there is an elastic expanding of the clamping sleeve, in which way the surface area 66 of the clamping sleeve 22 is pressed against the inner surface 67 of the spool sleeve 27 from the inside, and a transmission of the rotational motion 9 and the traversing motion 18 can occur. Preferably, the actuation surface 39 and the inclined surface 40 are realised as conical actuation surface 70 and conical inclined surface 69, where preferably the opening angle of the cone becomes lager than a self-locking angle.

[0069] The clamping sleeve 22 has an axial portion 71 in which the surface area 66 has an outer diameter in such a way that a play or a form fit to the inner surface 67 of the spool sleeve 27 results. In at least one further axial portion 72, which is arranged directly neighbouring the inclined surface 40 and/or the collar 50, the surface area 66 of the clamping sleeve 22 has an outer diameter which in an unloaded state is marginally larger than the inner diameter of the inner surface 67 of the spool sleeve 27, so that without effect of the actuation force in the region of the inclined surface 40 a clamping of the spool sleeve 27 onto the clamping sleeve 22 results. In this axial portion 72, the surface area 66 of the clamping sleeve 22 forms a contact surface 73 which in the clamping position is pressed against the inner surface 67 of the spool sleeve 27. The contact surface 73 in the axial portion 72 [0070] can be realised as continuous in the circumferential direction and over the entire circumference be pressed against the inner surface 67 of the spool sleeve or [0071] can only be realised in a partial circumferential portion which can for example be limited by the slit 63, where (possible with several slits 63) several contact surfaces 73 can be arranged distributed in the circumferential direction.

[0072] For the embodiment shown, the slit 63 separates a bowl- or bar-shaped segment of the clamping sleeve 22 oriented in the circumferential direction. This segment can be bent radially inwards around an axis oriented parallel to the longitudinal axis 11 with a bent bending rod oriented in the circumferential direction under creating the actuation force on the inclined surface 40, where a deformation region 74 in which the bending occurs is mostly arranged in the connecting region or “clamping region” of the separated bowl-shaped segment, while the contact surface 73 is mostly arranged in the end region of the separated bowl-shaped segment turned towards the portion 64 of the slit 63. For one of the multitudinous possible alternative embodiments, several slits 63 distributed around the circumference are only equipped with the axial portion 64 (that is, without portions 65). Between neighbouring slits 63, spring arms extending in parallel to the longitudinal axis 11 are then formed by the clamping sleeve 22, which are connected to the axial portion 71 in an end region while in the other end region it forms the collar 50 with inclined surfaces 40 each. In this case, the creation of the actuation force on the inclined surface 40 leads to the spring arms being bent around an axis oriented in the circumferential direction. Any other strains on the clamping sleeve 11 in the axial portion 72 for creating the radial clamping force or removing the radial clamping force are also possible.

[0073] FIG. 10 shows the interaction of the clamping sleeve 22 with the spool sleeve 27. The clamping sleeve 22 forms the surface area 66 which without actuation is pressed against the inner surface 67 of the spool sleeve 27.

[0074] The winding material 51 can for example be threads, yarns, ribbons or tapes, wires, stranded wires, monofilaments, multifilaments or similar. It is possible that the control unit 31 is equipped with control logic in such a way that a removal of the completely wound spool 2 and an insertion of a new spool sleeve 27 is made possible by the traversing carriage 20 being moved into a removal position outside of the usual stroke for the traversing motion 18.

[0075] The present winding machine 1 with regard to further aspects can be realised corresponding to the usual winding machines. For example, the measures according to the invention can be employed for winding machines which have two or more spindle units which are for example held on a revolver and where alternatingly one spindle unit is brought into a changing position while the other spindle unit is in a winding position. It is also possible that the invention is used for a winding machine in which on one spindle and a common traversing carriage or several traversing carriages several spools are arranged one behind the other and are wound at the same time. It is also possible that several concentrically arranged spools on two spindles are each created.

[0076] For the embodiment shown, the actuation of the traversing carriage 20 is done from the free end region of the spindle, in order to achieve which the leading of the traversing motion through the spindle is done by means of the actuation rod. It is alternatively possible that the actuation rod extends only up to the axial region in which the spool 12 is arranged and engages with a circumferential groove of the traversing carriage with a radially oriented pin which extends through an elongated slit of the spindle. Finally, it is also possible that the actuation of the traversing carriage 20 occurs from the side turned towards the machine frame 3 and radially on the outside as seen from the spindle.

[0077] It is possible also that several slits 63 of any and of the same or different shapes are provided on the clamping sleeve 22.

[0078] It is possible that through the radial clamping of the surface area 66 of the clamping sleeve 22 to the inner surface 67 of the spool sleeve 27 a friction-locking is induced which avoids an axial relative motion of the spool sleeve 27, possibly with the winding 28 formed on it, with respect to the clamping sleeve 22. Furthermore, by means of this friction-locking there can also be the transmission of the driving motion from the clamping sleeve 22 to the spool sleeve 27. Finally, a position fixing of the spool sleeve 22, possibly with the winding 28 formed on it, to the clamping sleeve 22 can occur with coaxial arrangement and centering of the spool sleeve 27 on the clamping sleeve 22.

[0079] For a different embodiment, in addition to the friction-locking between the clamping sleeve 22 and the spool sleeve 27 also a form-locking in the circumferential direction can be used to transmit the driving motion from the clamping sleeve 22 to the spool sleeve 27. To mention only an example, the spool sleeve 27 in the end region turned towards the machine frame 3 can comprise at least one axial slit, an opening or a groove with which a rib, a protrusion or an axially orientated pin of the clamping sleeve 22 engages with a pushing of the spool sleeve 27 onto the clamping sleeve 22. Via the connection between the slit, opening or groove and the protrusion, the rib or the pin, then there can be the transmission of the driving motion from the clamping sleeve 22 onto the spool sleeve 27. The other way around, the spool sleeve 27 can have a radially inwards oriented protrusion, a rib or a pin which then engages with an opening, a groove or a slit in the clamping sleeve 22. In the two mentioned cases then the friction-locking between the clamping sleeve 22 and the spool sleeve 27 is only or preferentially responsible for the axial fixing of the spool sleeve 27 on the clamping sleeve 22 and/or the centering or the pre-setting of the coaxial position of the spool sleeve 27 on the clamping sleeve 22. It is understood that a form-locking and a friction-locking can also complement each other for the transmission of the moment of torque. Possibly, for the transmission of the moment of torque via a form-locking, the application of the spool sleeve 27 onto the clamping sleeve 22 occurs for a given circumferential orientation of the spool sleeve 27 relative to the clamping sleeve 22.

[0080] The diameter, the wall strength, the material and the stiffness of the clamping sleeve 22 are preferably chosen in such a way that with the actuation of the clamping sleeve 22 a radial deformation results which results in a change of the radius of the clamping sleeve 22 in the region of the contact surface 73 in the region of 0.2 mm to 35.0 mm, especially 0.5 mm to 20.0 mm or 0.5 mm to 15.0 mm. The surface area 66 in the region of the contact surface 73 in the actuated configuration preferably has a radius which corresponds to the nominal size of the radius of the inner surface 67 of the spool sleeve 27 (possibly forming a play), while in the not actuated configuration without the spool sleeve 27 arranged on it the surface area 66 of the clamping sleeve 22 has a size that is larger by 0.5 mm to 20 mm with respect to the nominal size of the spool sleeve 27. The moment of torque transferable in a friction-locking way via the clamping sleeve 22 is strongly influenced by the material and the material strength of the clamping sleeve 22 and the spool sleeve 27. It is possible that the friction conditions between spool sleeve 27 and clamping sleeve 22 are influenced by a suitable coating of the surface area 66 and/or the inner surface 67 increasing the friction, for example with a coating made of rubber at least in the region of the contact surface 73. It is possible that the spool sleeve 27 is made of paper, plastic, aluminium or steel. The clamping sleeve 22 is preferably made of steel, aluminium or plastic. The moment of torque transmitted in a friction-locking way from the clamping sleeve 22 onto the spool sleeve 27 preferably is larger than 100 Nm.

[0081] For the shown embodiment a first coupling element 75 for transmitting the rotational movement of the spindle 8 to the traversing carriage 20 is embodied as the catch 23 and a second coupling element 76 for transmitting the traversing movement (and optionally also the rotational movement) of the traversing carriage 20 to the spool sleeve 27 is embodied as the spool sleeve clamping device 26. However, also other embodiments of the coupling elements 75, 76 for transmitting these movements are covered by the present invention.
