Definitions

  • the present invention relates to a spool for receiving winding material, and a corresponding spool component system according to the preamble of the independent claims.
  • the invention also relates to corresponding methods for fixing and separating the spool component system and for winding such a spool with a carrier spool.
  • a winding spool for a shippable winding for elongated winding material is known.
  • the winding spool includes a substantially rotationally symmetrical conical winding core, the first end having a smaller diameter than the second end.
  • a first flange is detachably connected to the first end of the winding core, a second flange is tightly fixed to the second end of the winding core.
  • the releasable connection between the first flange and the first end of the winding core is realized in this winding spool by segment latches provided on the first flange, which engage in corresponding latch openings provided on the first end of the winding core.
  • a so called all around latch directed inwardly towards the axis of rotation which is releasably in engagement with an oppositely directed all around latch on the flange.
  • the winding spool realized in this form-fitting connection between the winding core and removable flange is here configured altogether in such a way that both, assembly and disassembly of the flange by hand, is possible.
  • one or more second latch portions are provided on the first end of the spool core and one or a plurality of second latch elements are provided at the first flange, wherein the second latch portions are arranged on the spool core in such a manner and the second latch elements are arranged on the first flange and/or designed in such a manner that the second latching elements of the flange engage with the corresponding second latch portions of the spool core, when first latch elements provided on the first flange engage with corresponding first latch portions provided on the first end of the spool core, whereby a form-fitting connection between the first flange and the spool core is produced.
  • the same is mounted on the first end of the spool core, and—if the angular position of the first and second latch elements is not the same with respect to the angular position of the respective first and second latch portions—is rotated relative to the spool core until the angular position coincides.
  • the first latching elements of the first flange can engage with the corresponding first latch portions of the spool core, while the second latching elements of the first flange can be brought simultaneously into engagement with the corresponding second latch portions of the spool core, by pressing the first flange in the axial direction, preferably manually, onto the spool core.
  • relatively small forces are sufficient.
  • an engagement of the first and second latch portions and latch elements does not necessarily require a mutual rotation of the spool core and the first flange. Namely, if the first flange is applied in the right position in the circumferential direction, i.e. angular position, the first and second latch elements of the first flange can engage simply by axial sliding of the first flange on the conical spool core in the respective first and second latch portions on the spool core.
  • the first flange may be secured to the spool core in a simple manner in addition against twisting. Thereby, a more reliable fixation of the flange at the spool core is reached with a simplified design.
  • the spool is a cost-efficient, disposable and single-use spool, i.e. designed for a unique winding with winding material and its unique withdrawal.
  • the wall thickness of the spool core in this case is relatively thin and typically 1 to 3 mm, preferably about 1.5 mm.
  • the single-use spool itself has to be carried during the winding process by an appropriately dimensioned, in particular also conical, standard spool, since this is the only manner that the single-use spool is able to take the winding forces and that the torque of the propulsion of the winder can be transmitted via the standard single spool to the single-use spool.
  • the torque is thereby transmitted through friction and/or form-fit from the standard spool to the single-use spool.
  • the first and second latch elements and latch portions can, in this case, be advantageously configured so that a disengagement of the first flange from the spool core is no longer possible without an additional device or a suitable special tool, so that, after use, the spool cannot be readily disassembled, such as by manual operation of a pull tab as the winding spool known from WO 2005/070802 A1.
  • the latch elements or latch portions can be deliberately designed in a way to prevent any misuse of the spool of the invention preferably designed as a single-use spool as separable and possibly reusable spool. In this way, a simple, especially manual, disassembling of the spool for a space-saving return transport of the spool after removal of the winding to a new winding with winding material can be prevented.
  • the spool is designed as a reusable spool which is, after a winding and removal of winding material, available for at least another winding and removal of winding material.
  • the spool core has a wall thickness of typically 2 to 5 mm, in particular about 3 mm.
  • a support of the reusable spool by a further spool, as may be provided at a single-use spool, is hereby usually not necessary, but in principle possible when, for example particularly high winding forces occur or particularly high torque from the winder of the winding device have to be transferred to the reusable spool.
  • first flange is removed from the first end of the spool core.
  • Conical spool cores which have only a second flange at a second end with a larger diameter, can be pushed into each other and stacked in a space-saving manner.
  • first flanges which are preferably also designed stackable can be transported separately to a winding station where the first flanges are then fixed, preferably just before the winding process, again at the first end of the spool core.
  • first and second latch elements and latch portions may advantageously be designed so that a simple manual and non-destructive disassembly of the first flange from the spool core without an additional device or a suitable special tool is possible.
  • a tool is preferably introduced into the interior of the spool core, which at least partly disengages first and second latch elements in engagement with first and/or second latch portions, respectively.
  • a tool for secure and non-destructive disassembly of the first flange from the spool core has for example a conical stamp whose outer surface has an inclination to the axis of rotation which substantially corresponds to the inclination of the inner surface of the spool core.
  • a rod is provided on the stamp, by means of which the latter is inserted into the interior and is pushed, in particular pressed, towards the first end of the spool core.
  • Form and extent of the die are chosen such that this stamp can be pushed into the area of the first latch portions and may about there at the inner shell surface of the spool core.
  • first latch elements of the first flange engage from the outside in the first latch portions of the spool core, these are pressed radially to the outside by the extent portion of the conical stamp abutting on the inside in the area of the first latch portions and are disengaged or at least loosened from the form-fitting engagement that the first flange can be removed from the first end of the spool core.
  • the tool can, for example, have the form of a belt with loops which is put in the area of the first latch portions around the outer shell of the spool core and can be tightened with a suitable mechanism, whereby the first latch elements are pressed to the inside and in this way are disengaged with the first latch portions.
  • the first latch portions provided at the first end of the spool core have different angular positions with respect to the rotational axis of the spool core.
  • the first latch portions are displaced by an angle of about 45°, respectively, i.e. with respect to a first latch portion, the next first latch portion is arranged with a misalignment of 45° and the following first latch portion is arranged with a misalignment of 90°.
  • Pending on the number and dimension of the first latch portions these can also be displaced by smaller or larger angles. In principle, the angles can also have different dimensions. In total, this measure allows on the one hand a favorable distribution of forces over the surface over the first flange and therefore its reliable axial fixation and, on the other hand, a good securization against twisting can be reached.
  • the second latch portions situated at the first end of the spool core have different angular positions with respect to the rotational axis of the spool core.
  • the second latch portions can be displaced with respect to each other, for example by an angle of about 45°, respectively—according to the number and the dimension of the second latch portions, however also by smaller or bigger or angles of different size—.
  • a particularly reliable fixation of the first flanges at the spool core against twist can be reached.
  • At least one of the second latch portions has an angular position which coincides with the angular position of one of the first latch portions.
  • the first latch elements arranged at the flange have different angular positions with respect to the rotational axis of the first flange.
  • the first latch elements are each with an angle of about 45° to each other. Depending on the number and the dimension of the first latch elements, these can also be distant from each other by smaller or larger angels. Principally, the angles can also have different dimensions.
  • a cost-effective, particularly even distribution of forces over the surface of the first flanges and, therefore, its reliable axial fixation and, on the other hand, a good securization against twisting can be reached.
  • the second latch elements have different angular positions according to the rotational axis of the first flanges.
  • the first latch elements are misaligned by an angle of about 45° to each other, respectively.
  • these can also be displaced by smaller or larger angles or also by angles of different dimensions.
  • At least one of the second latch elements has an angular position which coincides with the angular position of one of the first latch elements.
  • at least one first and one second latch element has the same angular position.
  • the second latch portions are formed as protrusions and/or recesses at the first end of the spool core. This represents a possibility being particularly easy to realize two latch portions at the spool core. At the same time, a particularly good securization against twisting can be reached by the protrusions and the recesses, respectively.
  • the protrusions and recesses have an orientation parallel to the rotational axis of the spool core, respectively.
  • the protrusions and recesses are hereby preferably arranged in the area of the face side of the first end of the spool core and constitute hereby toothed or castellated extensions and dents, respectively, at the shell of the spool core.
  • the protrusions and recesses can, however, also have an orientation parallel to the surface of the shell of the spool core, respectively.
  • the protrusions, arranged preferably in the area of the face side of the first end of the spool core, and recesses are, for example, formed as toothed or castellated extensions and dents, respectively, which preferably align with the preferably tapered shell of the spool core.
  • the first latch elements and/or the second latch elements are formed in one part with the first flange.
  • the first flange comprising latch elements can hereby be produced in only one process step, for example as a die cast component, which is particularly favorable because of the cost advantages with respect to the advantageous usage of the spool as single-use spool.
  • interspaces are provided between the first latch elements provided at the first flange, which are adapted to the particularly tapered form of the spool core that the interspaces in the area of the first end abut when the first latch elements of the first flanges engage with the corresponding first latch portions of the spool core.
  • the interspaces have an inner portion, viewed in radial direction, which is inclined with an angle between about 3° and 9°, in particular about 6°, with respect to the rotational axis of the flange.
  • a reliable abut of the interspaces at the spool core can be realized in a simple manner.
  • the first latch elements being formed as axial protrusions at the first flange and the protrusions having a latch nose, respectively, which can engage with the corresponding latch portions at the first end of the spool core.
  • the axial protrusions run essentially parallel to the rotational axis of the first flanges.
  • the respective latch noses preferably protrude from one end of the axial protrusion in direction to the rotational axis, this means that these are orientated essentially in radial direction to the inside.
  • a secure latching of the first latch elements of the first flanges in the first latch portions at the spool core can be realized in an easy manner.
  • the latching nose has a in particular flat slant which, viewed in radial direction, lies inside and inclined by an angle between about 20° and 40° with respect to the rotational axis of the flange, in particular about 30°.
  • An opposite area of the latch nose to the slant runs preferably normal to the rotational axis of the first flange.
  • the first latch elements can engage from the outside in the first latch portions at the first end of the spool core.
  • the first latch elements are hereby formed such that these can be pressed during a winding of the spool core by the winding material in direction of the latch portions, particularly radially to the inside.
  • the first latch elements of the first flange latch hereby from the outside in the first latch portions of the spool core.
  • the latch elements formed as protrusions with latch noses are hereby dimensioned and/or shaped that a great share as possible of the forces exerted by the winding material are transmitted in radial direction on the first latch elements.
  • the protrusions of the first latch elements run essentially parallel to the rotational axis of the first flange or to the surface of the shell of the spool core.
  • the protrusions of the first latch elements are so high with respect to the base of the first flange facing the spool core that possibly several, preferably a multitude of windings of the winding material can come to rest up on these.
  • the height of the protrusions is between 5 and 20 mm, particularly between 8 and 12 mm.
  • the method for winding an inventive spool with winding material has the following steps: Setting up the spool on a carrier spool which has a preferably conical carrier spool core and at least a flange arranged at an end of the carrier spool core and starting to rotate the carrier spool, wherein the spool put on the carrier spool also starts to rotate and is thereby wound up with fed winding material.
  • This method is characterized in that the flange of the carrier spool is coupled form-fittingly with the support of at least one actuator provided at the flange of the carrier spool with a flange of the spool.

  • the radial extension d 9 of the latch nose 22 is preferably about 2 mm.
  • the dimensioning, arrangement and form of the latch nose 22 can vary considerably of these sizes, however.
  • the radial extension d 9 can be considerably larger as 2 mm, for example in order to secure a particularly reliable fixation of the first flange 5 on the spool core 1 if, for example, the spool has to hold a lot of winding material. The same applies correspondingly for the other here cited parameters.
  • the intermediate range 23 can be seen, which lies—with respect to the drawing plane—behind the first latch element 20 and which has at its lower end a radial protrusion 25 , which forms together with other protrusions (see FIGS. 4 and 5 ) interspaces or gaps which realize the second latch elements 21 in the shown example.

  • first latch portions 10 can be seen as recesses in the form of slots in the spool core 1 in which latch noses 22 of first latch elements 20 engage from the outside. With exception of the first latch elements 20 arranged at the side, the remaining first latch elements are covered by the shell of the spool core 1 and are therefore in the here chosen representation visible.
  • second latch portions 11 can be seen, which engage in second latch elements which are formed by areas between radial protrusions 25 at the first flange 5 .
  • the spool is designed as single-use spool, particularly with relatively low wall thicknesses of the spool core 1 between 1 and 3 mm, the first and second latch portions 10 and 11 , respectively, and latch elements 20 and 21 , respectively, are formed such that an easy and non-destructive loosening of the first flange 5 from the spool core 1 by hand is not possible.
  • flange 5 is loosened with support of an adequate tool adapted to the respective spool easily, fast and non-destructive.
  • the tool shown as an example in FIG. 10 is, for reasons of clearness, only shown dotted and comprises a stamp 30 on which a rod 31 is installed, provided with a handle 32 .
  • the tool is inserted from the second end 3 of the spool core ? in the inner of the spool.
  • the stamp 30 preferably has a conical form which is adapted to the form of the inner shell of the spool core 1 , in particular in the area of the first latch portions 10 , and can be realized for example as rotationally symmetric disk or cap.
  • the stamp 30 can be displaced by a user with the handle 32 and the rod 31 in direction 34 on the first end 2 , where it can be brought finally in the area of the first latch portions 10 in abutment with the inner shell of the spool core 1 and thereby presses the latch noses 22 of the first latch elements 20 , engaging in the first latch portions 10 from the outside radially to the outside.
  • first latch elements 20 are disengaged with the corresponding first latch portions 10 such that the first flange 5 can be removed without problems in direction 34 from the spool core 1 .
  • a lifting of the first flange 5 in the direction 34 parallel to the rotational axis 6 is not hindered by the second latch portions 11 and latch elements 21 , respectively, which are even then in engagement, since these, in the shown example, contribute primarily to an augmented protection against twisting and effects no further fixation in direction 34 .
  • the tool has to be designed such that this can also disengage the second latch portions 11 and latch elements 21 , respectively, at least partly in order to render possible a loosening of the first flange 5 .
  • first latch elements 20 in particular the latch noses 22 and/or of the first latch portions 10
  • first flange 5 of spool core 1 can be removed without any further application of force if the latch noses 22 can be pressed by the stamp 30 a small distance in direction 35 radially to the outside without, however, disengaging these fully from the latch portions 10 .
  • the axial forces exerting in this state, this means during a part engagement between the latch noses 22 and the corresponding first latch portions 10 can be overwound by relatively small forces in direction 34 during the removing of the first flange.
  • FIG. 11 shows a sectional view of the inventive spool 9 , which is partly put on a carrier spool core 41 of a carrier spool 49 .
  • a first flange 5 and a second flange 4 are installed.
  • the above explanations for installing the flanges 4 and 5 at the spool core 1 apply accordingly.
  • the spool 9 is in the here shown example a single-use spool, wherein the wall thicknesses of spool core 1 are relatively thin and typically 1 mm to 3 mm, preferably about 1.5 mm.
  • the carrier spool 49 is a reusable spool whose wall thickness of the carrier spool core 49 is higher as at the single use spool and typically between 2 mm and 5 mm, particularly about 3 mm.
  • a second flange 44 is provided in the here shown representation at the above end of the of the carrier spool core 41 which is rigidly connected with the carrier spool core 41 in which the same is, for example, formed in one part with the carrier spool core.
  • every other fixed connection which can particularly not be loosened, is possible.
  • the other, in this representation lower, end of the carrier spool core 41 is designed such that it is detachably connected with the first flange 45 of the carrier spool 49 .
  • a detachable connection can hereby be realized, for example, by segment latches provided at the first flange 41 which engage with corresponding latch openings provided at the open end of the carrier spool core 41 , as for example know from the winded spool from WO 2005/0700802 A1.
  • two carriers 42 are provided which are for example formed in one part with the first flange 45 , as these are for example formed together with the first flange 45 in a single die mold process. Principally, it is also possible that the carriers 42 are installed afterwards at the flange 45 , for example by plugging, screwing or gluing.
  • the first flange 5 of the spool 1 has an essentially flat base 26 , on whose backside, i.e. the side averted from the spool core 1 , ridges 27 are formed whose function is primarily to stabilize mechanically the base 26 of the flange 5 .
  • ridges 27 With respect to the position and the design of the single ridges 27 , it is referred to the example of an embodiment in the FIGS. 4 , 5 and 7 of a first flange 5 including the respective explanations.
  • the ridges 27 formed on the base 26 are arranged such that these form an interspace in which the respective carrier 42 can engage at the first flange 45 of the carrier spool 49 when the spool 9 is put completely on the carrier spool core 41 and the first flange 45 is, preferably detachably, fixed at the open end of the carrier spool core 41 . This is shown in FIG. 12 .
  • the coupling of the two spools 9 and 49 is enhanced additionally in that the inside of the spool core 1 of the spool 9 abuts at least partly at the outside of the carrier spool core 41 of the carrier spool 49 and whereby the spool core 1 is coupled frictionally with the carrier spool core 41 .
  • the coupled spools 9 and 49 can be placed in a winding device (not shown), in which the carrier spool 49 rotates around the symmetrical axis 6 .
  • a winding device not shown
  • the carrier spool 49 rotates around the symmetrical axis 6 .
  • the first flange 45 of the carrier spool 49 is placed on a spool seat which is propulsed by a motor and thereby rotated.
  • the second flange 44 of the carrier spool 49 is hereby coupled with a further spool seat which is also rotatable seated, however, which does not have to be powered motorically and which serves essentially as mechanical stabilization for the rotating spools 9 and 49 during the winding.
  • FIG. 13 shows a first flange 45 of the carrier spool 49 in different representations.
  • holding protrusions 43 can be seen, by which the first flange 45 is detachably fixed at the lower end of the carrier spool core 41 of the carrier spool 49 , as the holding protrusions 43 engage under corresponding latch protrusions which are arranged at the free end of the carrier spool core 41 .
  • WO 94/13570 A1 With respect to further details of the design of the holding protrusions 43 as well as the corresponding latch protrusions on the carrier spool core 41 , it is referred to WO 94/13570 A1.
  • two carriers 42 can be seen in the shown top view (a). These are formed in the present example at a side of the base 46 of the first flange 45 , as can be seen from the side view (b), the first perspective view (c) as well as the sectional view (e).
  • the second perspective view (d) shows the first flange 45 of the carrier spool 49 from the backside of the base 46 , which is provided there with a multitude of reenforcing ridges 47 .
