Abstract

Winder for a shipping container for elongated winding material as it has become known from WO 2005/070802 A1. In this case, this container has a slenderness ratio of l / t (-) in the region of a hollow conical section. Furthermore, this aspect ratio is based on the modulus of elasticity of the material used in this area.

Description

The present invention relates to a reel spool for a shipping container for elongated winding material, in particular for winding material containing metal, such as wires, strands, insulated sheathed cable and the like.

The invention further relates to a method for producing a container capable of being shipped, and to a method for processing a container capable of being shipped for elongate winding material using a winding bobbin according to the invention and a container for transportable winding material. The invention is suitable for all elongate winding material, which is usually wound on (winding) coils.

With the European patent EP-B-0 334 211 discloses a process for producing an unpacked transportable container, in which a collapsible steel coil is used, on which a gray cardboard or corrugated cardboard sleeve is placed. Both the steel coil and the cardboard tube have a conically shaped core. The winding of the coil starts at the end of the winding core which has the smaller diameter, and is performed with a laying device moving parallel to the longitudinal axis of the spool such that the length of the winding layers is increased substantially continuously, as viewed in the longitudinal direction of the spool , so that a so-called doppelkonischer structure of the winding results.

The deduction of the cable from this container is usually carried out by the stationary coil and with a vertically oriented longitudinal axis, whereby also here the winding core is arranged with the smaller diameter at the bottom. When pulling the cable over the upper coil flange of the remaining part of the coil on the coil remains stable due to the biconical structure, so that the entire cable can be removed without interference. This winding method is used today by numerous cable manufacturers.

Another method for producing a transportable container is in the EP 0 504 503 B1 described. In this shipping system, a conical core made of plastic is used, at the end of larger diameter, a flange is arranged. At the end with the smaller diameter no flange is provided.

For winding the winding core is arranged with the large flange diameter down into a winding device and connected to a metal disc, which is part of the winding machine, as a replacement for an upper spool flange with the winding core. After winding, the metal disc in the machine is removed again and the container is provided with a film wrapping for shipping.

The system is very stable for shipping, but has the disadvantage that on the one hand the hub must be returned to the cable manufacturer, so that the system is economical, and on the other hand, the cable wrapper must be disposed of the film wrapping.

As a further development of the first-mentioned method for producing a transportable container is with the EP 0 672 016 B2 a method has become known in which a specially designed winding spool made of plastic is used. The winding spool, which in 2 is conical and has at its end with a smaller diameter on a connected via a special locking system with the winding core, removable flange. This coil is usually taken in a vertical arrangement of the coil axis with the smaller diameter of the winding core facing down in a winding device and, as in the former method, provided with a doppelkonisch constructed winding.

The winding device for winding the reel spool is in 1 shown. Since the winding spool itself has sufficient stability, the winding device only has to be designed in such a way that the winding pressure, which is quite high in this type of winding, can be reliably absorbed by the flanges. The cable is withdrawn from the stationary coil at the cable user as in the above-described container, in which case the cable can be pulled off to last, without the stability of the container decreases and leads to problems during removal.

In this connection it should be noted that these coils are used in particular for supplying cables which are used for the production of wire harnesses for motor vehicles. When assembling these wiring harnesses, the required length of cable is drawn from the stationary coil at high speed, and the cable is then held in a holding device after cutting until the next piece of cable is needed.

This high-speed intermittent trigger requires a particularly stable winding structure, as jamming of the cable during unwinding usually results in cable breakage and production interruption. For the return transport of the plastic coils, the flange is removed at the end with the smaller diameter and winding core and flanges space-saving stacked on each other. Thus, only a small transport volume is needed for the return transport.

The latter method, commonly referred to as NPS (N (iehoff) -P (aket) -S (ystem)), is used by numerous cable manufacturers throughout the world, particularly for cable delivery to the automotive industry. However, this shipping system can not meet all the requirements of cable users. Thus, the concentration process in the cable manufacturer industry has meant that such containers are transported over long distances to ship. Since in this case the cycle time of a coil, that is, the time that elapses until the coil has arrived from the cable manufacturer at the cable user and processed there and transported back, so high that an extremely high number of reel spools would be needed.

Since the cost of the coils usually has to be borne by the cable manufacturer, these make the use of the system uneconomical for the cable manufacturer in such a case. Furthermore, in spite of the small transport volume with increasing distance, the costs for the return transport of the empty bobbins also increase, so that the transportation costs of the empty bobbins become too high in relation to the value of the bobbins.

Finally, there are cable users who shy away from the burden of collecting and returning empty reel spools, so that the relatively expensive reel spools of the aforementioned system are lost to the cable manufacturer. The cable manufacturers therefore have the desire for a transport system, which on the one hand works just as reliably as the NPS system, which on the other hand, but also for large transport routes is economical.

With the international patent application WO 2005/070802 A1 is a winding bobbin for receiving an elongated winding material and a method for its preparation and for the development of the Wickleguts known. In this winding coil, a part of a plastic low strength, which is recyclable. Further, a hollow tapered portion of this coil is designed as a thin-walled portion, in particular, the portion for receiving the winding material is designed as a flexible plastic skin.

The present invention is therefore an object of the invention to provide a winding spool for a shipping container, a method for producing and for unwinding a shipping container and a container available, with which can be realized an economical and reliable transport system.

This object is achieved by a winding spool for a shipping container for elongated winding material, by a method for manufacturing and by a method for handling a shipping container for elongated winding material using a corresponding winding spool and by a container for elongated winding material with the features according to the respective independent Claim solved.

The winding reel according to the invention for a shipping container for elongated winding material comprises a substantially rotationally symmetrical, conical, hollow winding core attachment made of plastic. In this case, the aspect ratio of the wall of this conical section is chosen as a function of material parameters of this plastic, in particular chosen such that a deformation, in particular affecting the winding, in these areas is avoided or reduced.

In the case of the invention, a winding core attachment is to be understood as a sleeve-like body which serves as an attachment to a carrier system, in particular a carrier body. Carrier cores of known (carrier) winding coils (carrier coils) or functionally identical other carrier bodies can serve as carrier systems or carrier bodies. This winding core attachment according to the invention is therefore not a winding core of a conventional winding spool.

Conventional winding bobbins are in direct contact with a winding bobbin receiving device of a winding device and have higher strength and in particular higher rigidity than the winding core article according to the invention.

However, the winding core attachment according to the invention can be carried by such a conventional winding reel or another functionally identical carrier system during its winding with a winding material without being in direct contact with a winding reel receiving device.

The winding core attachment according to the invention has a first end with a smaller diameter and a second end with a larger diameter than the first end.

A cavity of the hollow winding core attachment is conical and open on both sides, in particular for receiving a carrier system or carrier body, such as a winding core designed.

The winding core attachment is further - like a conventional winding core of a divisible winding coil - with at least a first flange, which at the first end of the winding core is detachably arranged, and connected to at least one second flange, which is arranged at the second end of the winding core attachment.

The conical, hollow portion of the winding core attachment, which is arranged between the two flanges, has a thin-walled design with a length l (extension between the two flanges) and an average wall thickness t. Further, this hollow conical section has as an essential component or preferably consists of it, a plastic with a modulus of elasticity (modulus of elasticity) in the range of 1000 N / mm ² to 30000 N / mm ² . For the purposes of the invention, an essential constituent is also to be understood as meaning a matrix material of a fiber composite material, even if the fiber fraction is large and the proportion of the matrix material is low.

The geometric design of this conical hollow section is oriented according to the invention on the material characteristics of this plastic, at least on its modulus of elasticity. In the sense of the invention, orientation of the design is to be understood as meaning that a correlation of the factors geometry of the section in question and material properties (modulus of elasticity) of this section results in that in the design of the reel spool according to the invention a material with a different e Modulus, with otherwise constant geometry, leads to a different aspect ratio (l / t) of the hollow conical section.

The slenderness ratio according to the invention is chosen so that the product of the modulus of elasticity (N / mm ² ) and this aspect ratio (mm / mm) is preferably greater than 0.1 times 10 ⁶ , preferably greater than 0.2 times 10 ⁶ particularly preferably greater than 0.3 times 10 ⁶ , preferably less than 2.5 times 10 ⁶ , preferably less than 1.5 times 10 ⁶ and particularly preferably less than 0.8 times 10 ⁶ . Most preferably, this product is essentially 0.5 times 10 ⁶ .

In the method according to the invention for producing a container capable of being shipped for elongated winding material, this winding bobbin according to the invention is used.

The winding reel according to the invention has a substantially rotationally symmetrical, conical, hollow winding core attachment made of plastic, with a slenderness ratio l / t, which is oriented to the material characteristics of this plastic, in particular to its modulus of elasticity. This section has a first end with a smaller diameter and a second end with a larger diameter than the first end.

A cavity of the hollow winding core attachment is conical and open on both sides, in particular for receiving a carrier system or carrier body, such as a winding core of a so-called carrier winding coil, short carrier coil designed.

The winding core attachment is further connected to at least one first flange, which is detachably arranged at the first end of the winding core attachment, and to at least one second flange, which is arranged at the second end of the winding core attachment.

In the method according to the invention, the winding bobbin according to the invention is assembled by releasably connecting the first flange to the winding core attachment at the first end.

The winding bobbin thus composed is placed on the carrier system, for example, a known, divisible winding bobbin, such as the divisible, from EP 0 672 016 B2 known winding spool ( 2 ), put on.

The carrier system or the carrier coil, together with the winding coil placed on it according to the invention, converts into a winding device suitable for wrapping the carrier system, for example the known, divisible winding coil, such as, for example, US Pat EP 0 672 016 B2 known winding device ( 1 ), brought in.

Usually, a common divisible winding spool is introduced into a winding device in such a way that the winding spool is accommodated in the winding device by means of two spool receiving devices, which center flanges arranged on both sides of the winding spool and support them on their surface facing away from a winding core of the winding spool.

In the case of the method according to the invention, the carrier coil would thus be taken up in the winding device as is known - with the difference according to the invention that in this case the carrier coil carries the winding reel according to the invention (as an article to be wound).

Next, in the method according to the invention, a winding material is wound onto the winding bobbin according to the invention - not as usual on the winding bobbin received directly in the winding device - using a laying device which, for example, is known EP 0 672 016 B1 , Is controlled by a control device such that there is a predetermined winding pattern on the winding bobbin according to the invention. Once a desired degree of filling of the winding bobbin according to the invention is achieved, the winding process is terminated and the carrier system or the Carrier coil taken together with the attached to it according to the invention and wound reel spool from the winding device.

The splittable carrier coil is split and the winding coil placed on the splittable carrier coil and wound, according to the invention, is removed from the carrier system or the carrier coil. With the wound winding bobbin according to the invention is thus the shipping container before.

The method for processing a shipping container for elongated winding material using

• - Having a first and a second flange, wherein the winding core attachment with at least the first flange, which is detachably arranged at the first end of the winding core and the second flange, which is arranged at the second end of the winding core, connected, has the following Procedural steps on:

• Unwinding a winding material from the wound reel spool using a drainage device,
• - Ending the unwinding process, as soon as a desired unwinding level is reached, and
• - Remove the unwound to the desired Abwickelgrad winding reel from the winding device.

The container has a substantially rotationally symmetrical, conical, hollow winding core attachment made of plastic, which has a first end with a smaller diameter and a second end with a relation to the first end of larger diameter. A cavity of the winding core attachment is conical and open on both sides. The conical, hollow section has a specific slenderness ratio, whereby this slenderness ratio is oriented on material characteristics of the plastic, in particular on its modulus of elasticity.

The container further has a flange which is fixedly connected to the second end of the winding core attachment. Furthermore, the container has a cable, which is wound according to a predetermined winding pattern on the winding core.

Illustratively, the invention is based on the consideration of a known winding system with a reusable winding reel, such as, for example EP 0 672 016 B1 known to provide as a carrier or other functionally identical carrier body as a support system for a less expensive to produce, to be wound disposable coil with sufficient rigidity. As a result, the invention can be clearly described as "a disposable coil which can be placed on a reusable coil or a functionally identical carrier body".

It has been found in the use of disposable coils whose section between the two flanges as an essential part of a plastic or consists of such, that it in the handling of this, so in the winding, handling, storage the transport or the like to Irregularities can come. This is to be understood in particular that the position of the elongate winding material on the winding bobbin may change, so that in the worst case, no complete unwinding of the winding material from the bobbin is possible. In such winding coils in particular the flanges are exposed to high winding pressures, the hollow, conical section between these flanges is exposed to lower loads. In order to accommodate a large volume of winding on the reel spool, the hollow, conical section with a small wall thickness, so to speak as plastic skin, designed. The flanges, however, are designed so that they withstand the high winding pressures.

Even with the utmost care when winding the container, during storage and transport and during unwinding of the same, can not be ruled out that acts in these manipulations force effects on the winding material, in particular radially inward. If this force action exceeds a certain threshold, then a thin plastic skin in the region of the conical, hollow portion can no longer withstand these force effects, although the stability of this alone would be sufficient for transport, then elastic deformation can occur. As a result, it may thus lead to a change in the layers of the winding material, these changes in turn, can lead to problems when unwinding the winding material or to the fact that the container can not be fully applied to the hub core, as the hollow, conical Section has deformed radially inward.

Further, there are a variety of different sizes of containers, so that a certain wall thickness at a certain length of the hollow conical section is sufficient in the sense that the aforementioned problems do not occur, with the same wall thickness and other length of this section the problems occur. Next are used for winding coils in different sizes but sometimes also for winding coils of the same geometry, different materials in the production. This results in the problem that at a certain slenderness ratio with a certain material, the previously described problems do not occur when using a different material and the same geometry, but the previously described problems occur.

In order to enable a secure, reliable unwinding of the package, it is therefore necessary to consider both the geometry and the material in the design in addition to the strength and stability of the reel spool. The design of the reel spool according to the invention makes it possible to design the reel spool for different package sizes and materials in such a way that reliable unwinding is possible on the one hand and that the volume of reel to be taken up by the reel spool on the other hand is as large as possible under this condition.

Furthermore, the advantage of these disposable winding coils is maintained that the carrier system, for example a known winding spool, can be used without necessary conversions on the carrier system as usual in the "direct" winding, but also for the "indirect" winding on the Carrier system or the original reel spool, d. H. in this case the carrier coil, mounted winding bobbin according to the invention. In the development of the winding bobbin according to the invention, a carrier system or carrier body, such as a carrier coil, as in the winding or not absolutely necessary.

Through the possible recourse to the known winding system, for example the known NPS winding system, which can be used by the invention, its advantageous characteristics can also be utilized. Thus, in the wound winding bobbin according to the invention, the same winding patterns as in the case of the NPS winding bobbin can be realized. It is also possible to realize partially filled or partially unwound winding bobbins.

When draining, opened containers can be stored again. The same shipping logistics as well as the same lifting tools as in the NPS winding or NPS transport system can be used in the invention. This can be in an advantageous manner with the original winding system, such as the known NPS winding system, two different winding systems, the reusable NPS winding system and the inventive disposable system with the disposable coil realize.

The attachable, to be wound disposable coil includes similar to a known separable reusable spool, such as the known NPS winding system, a winding core similar co-writable part, namely the winding core, which is placed on the carrier coil or on the winding core of the carrier coil.

Furthermore, the attachable winding bobbin according to the invention, similar to a divisible winding bobbin, has at least one flange detachably connected to the winding core attachment. A second flange may be fixed or detachably connected to the winding core attachment. This divisible construction of the winding device according to the invention makes it possible for a plurality of the first flanges and / or a plurality of the winding core attachments and / or a plurality of the winding coils to be stackable in a developed and / or wound and / or transportable state. This can be in the invention, the advantages of a container, as with the EP-B-0 334 211 has become known, with the advantages of a container, such as the EP 0 672 016 B1 , combine.

Accordingly, the disadvantages of both systems can be circumvented by the inventive system "the disposable coil which can be placed on a carrier system or a reusable coil". Also, the invention has the advantage that in the filled winding spools no strapping is necessary.

Further advantages of the invention are mentioned below.

Preferred developments and embodiments of the invention will become apparent from the dependent claims and relate both to the reel spool according to the invention as well as to the inventive method and the container.

As a material for the winding bobbin according to the invention in particular plastics, such as polyurethane, polyethylene (PE), polypropylene (PP), polystyrene, acrylonitrile butadiene styrene (ABS) come into question. The plastic may, if higher strength requirements or higher stiffness requirements are to be met, be reinforced with suitable means, such as glass fibers. In a preferred embodiment, different components of this reel spool on different materials, or consist of different materials. Preferably, the conical, hollow portion of the reel spool is made of a different material, such as the releasable flange. Preferably, the releasable flange as an integral part of PE, or consists of this. Further preferably, the conical, hollow portion and integrally formed with this flange as a essential component PP, respectively, consists of this. Further preferably, the reverse combination of the materials described above is possible. Through the use of different materials with different technical properties, the adaptation of areas of the reel spool to the stresses occurring there is made possible without the need to significantly change the manufacturing tools.

In a preferred embodiment, the winding core attachment according to the invention consists of a thin plastic, for example an elastic, recyclable plastic, such as PP or PE. However, this thin plastic is not designed as plastic skin, in particular in the region of the hollow, conical section of the reel spool, but with a significant average wall thickness t, so that deformation of this section is reduced or avoided radially inwardly under the force effects occurring during the handling of the reel spool and this is thus preferably quasi-rigid. By means of this rigidity, which can be achieved by the slenderness ratio l / t according to the invention in combination with the modulus of elasticity of the plastic, reliable operation, in particular problem-free unwinding up to the last layer of the winding material, is achieved, thus providing an improved winding spool.

While it can not be achieved in the inventive design of the reel spool that the hub core the manufacturing technology minimally achievable wall thickness (plastic skin) and thus a maximum of elongated winding material on the coil is receivable, since the wall thickness in the region of this hollow, conical section not according to the invention as plastic skin is executed, but the predetermined slenderness ratio is sufficient.

However, the theoretically generated by the inventive design loss of winding volume per reel spool is (over) compensated that this design ensures that the winding material can be completely unwound from each reel and so, especially in the last layers of the winding material, Problems when unwinding the coil can be reduced or avoided, which can be caused by a deformation of the reel spool, in particular in the radial direction inwards. Thus, by reducing the theoretical winding volume, but by lowering irregularities in unwinding the bobbin, particularly by avoiding deformations of the hollow conical section of the bobbin, by the inventive design of this section, the usable winding volume can be increased overall inventive design an improved reel spool displayed.

However, due to the low weight and relatively simple construction of the hub core can be made very inexpensive, so that the cost of "lost" disposable winding coils, d. H. The winding bobbins according to the invention are used once, for the cable manufacturer not substantially significant.

On the other hand, however, the winding device according to the invention due to their stackability, which results from the detachable or divisible design of the winding bobbin according to the invention, quite well used in a reusable system, in which case the detachable flange is separated from the winding core attachment. The winding bobbin according to the invention can thus be transported in the unwrapped state by separate winding core attachment and releasable flange and the winding core attachments and spool flanges are stacked to save space. In the case of winding bobbins according to the invention with thin-walled winding core attachments, up to 250 empty bobbins can be stacked and transported on a Euro pallet.

If the winding core attachment, according to a preferred embodiment of the invention, made from a single-grade plastic, this can be ground into granules immediately after unwinding of the cable in a with included in the processing process grinders and further processed in the recipient country in plastic factories.

Since the winding core attachment, according to a preferred embodiment, consists of plastic, when shipping the system into hot and / or wet countries, it does not change the geometry or other properties of the container.

It has been shown that in contrast gray cardboard and / or corrugated cardboard as a container carrier in countries with hot and / or humid climate causes problems, since gray pack absorbs water and then warps or depending on the prevailing humidity swells or shrinks, and further water absorption also decays. It should be noted that the containers are exposed to an extremely humid climate during ship transport for several days or weeks. Furthermore, in a surface of the winding core support, which is wound with the winding material, a pattern, such as a herringbone or scale pattern, be incorporated. As a result, among other things, the static friction between the winding material and the winding core support increases and thus the container can be stabilized.

In a further preferred embodiment, the smaller diameter at the first end of the cone-shaped winding core attachment has a diameter of slightly more than 203 mm, the diameter of an NPS coil which can be used as a carrier system at this location. As a result, the flow behavior of the winding bobbin according to the invention can be improved. The use of divisible plastic coils as carrier coils for the reel spool according to the invention has the advantage that the weight of the entire coil device introduced into the winding device, ie the carrier reel with the winding reel attached according to the invention, is still relatively low. Thus, the imbalances resulting from inevitable diameter deviations are relatively low even at high rotational speed of the carrier coil.

This means a considerable difference to the use of steel coils, as they are known in the art, since their high weight proves to be disadvantageous especially at high speeds. The two flanges can be made of the above-mentioned plastics, in particular of an elastic, recyclable plastic, such as PP or PE. Furthermore, the second flange can serve as a drain ring. Also, the flanges may be conical and / or cone-shaped, which ensures that at a constant winding width at the flange a small valley is formed and thereby a flange pressure in the winding bobbin according to the invention is reduced.

In a preferred embodiment, the flanges can be equipped with carrying eyes, in particular for lifting tools, and / or with tear-off tabs, in particular suitable for opening an all-round catch.

In a further preferred embodiment, the first releasable flange is connected to the winding core attachment via a special locking system. Such a locking system can be realized using segment catches, stacking openings and / or an all-round catch, which are at least partially, but preferably incorporated in their entirety, in the first flange. In this case, the winding core attachment according to the invention has corresponding counterparts, preferably openings. These Segmentrastungen, stacking openings and / or Rundumrastung with these counterparts, preferably openings, can be brought into engagement.

Preferably, the segment detent or Rundumrastung is designed so that when engaged this results in a substantially continuous surface course in the region of the detent. According to the invention, locking sections are provided in the hollow, conical section, which are designed as recesses, preferably pocket-like recesses. These recesses are adapted to latching projections or latching engagements, which are preferably arranged on this detachable flange, record in the locked state so that a continuous surface course is formed, in particular so the inner surface of the hollow conical portion and an end face of this section have a substantially continuous course , in particular not disturbed by steps, paragraphs or the like.

These recesses extend from the end face of the hollow conical section toward the non-detachable flange (axial direction). Further preferably, these recesses are designed so that they represent in the radial direction, based on the hollow, conical section, a reduction in the wall thickness of this section, preferably by a measure k2.

This measure k2 is oriented to the wall thickness of the region of the latching engagement, which engages in the latched state in this recess and at the wall thickness t of the hollow, conical portion which has this outside of this recess. Preferably, the latching engagement, at least partially or completely, and formed as pocket-like recesses latching portion of the hollow, conical section, in each case approximately half the wall thickness t. Further preferably, the wall thickness of the latching engagement and the wall thickness of this pocket-like recess results in the sum of approximately the wall thickness of the hollow, conical section, or corresponds to this.

Further preferably, these recesses are also offset in the axial direction from the end face of the hollow conical section, preferably by a dimension k1. Further preferably, these recesses are offset in the axial direction in about as far as the thickness of the wall of the locking engagements in this area. By this settling arises in particular a burgzinnenartige shape of the hollow, conical section in the region of the end face.

Due to this geometrical adaptation of these pocket-like recesses and these locking engagements, a particularly good locking of the releasable flange with the rest of the winding spool can be achieved in particular. Further advantageously, the coil can be particularly well placed on a support coil, in particular so that only a small or no cavity hiss the hollow, conical section and the support coil arises, as this can occur when the surface profile is discontinuous in this area.

By this design of the detent, in addition, a shape of the reel spool, which comes close to an advantageous one-piece design of the releasable flange with the rest of the reel spool.

The Rundumrastung may moreover interruptions, preferably small interruptions, which facilitate the release of the first flange of the winding core attachment, for example by tearing open the Rundumrastung. Furthermore, a closure system can be realized which is similar in function to the sealing systems known from paint buckets.

Further, on one of the flanges, in particular on the first releasable flange, a lifting lug for use with a hoist and / or a handle with a pull-tab may be provided for separating the at least one flange from the winding core attachment (cone part). Further, in the flanges stack openings and / or Segmentrastungen and / or a Rundumrastung be provided. Furthermore, ribs can be incorporated in the flanges.

In a further preferred embodiment, the connection between the winding core attachment and the detachable flange is designed in a form-fitting manner, preferably by latching elements which are arranged on the winding core attachment and on the coil flange and which are brought into engagement with one another during assembly.

In a further preferred embodiment of the reel spool, the second flange is not removable at the end of the larger diameter end of the reel hub. The second flange is then preferably formed integrally with the winding core attachment and can be produced together with this, for example by an injection molding process.

In order to facilitate the stacking of full bobbins, projections and indentations are preferably provided on the outer sides of both flanges, that is to say, on the side remote from the winding core attachment, which engage in one another when wound bobbins are stacked on one another. This further simplifies the transport of the wound coils. Preferably, openings for stacking (stacking openings) are incorporated in one of the two flanges, more preferably in the first releasable flange, to facilitate stacking, preferably to facilitate centered stacking.

Preferably, the winding bobbin according to the invention is applied to a carrier coil and introduced into a winding device that the winding bobbin according to the invention is arranged in a vertical arrangement of the coil axis with the smaller diameter of the winding core support facing down in the winding device and, according to known winding method, constructed with a doppelkonisch Wrapping is provided.

The winding reel according to the invention, in particular its hollow, conical section, is designed so that a deformation of this section is reduced or avoided radially inward. In accordance with the invention, this is achieved by a slenderness ratio oriented on the material characteristics for the material used in this area, in particular its modulus of elasticity. It is not sufficient alone that the winding pressure quite high in this Bewicklungsart can be reliably absorbed by the flanges, but it is also necessary that force effects, which can occur when handling the reel spool, in particular radially inward, not to a Deformation, in particular the wound-up layers of the elongated winding material lead, this can be achieved by the inventive design of the reel spool.

In a further preferred embodiment, a weight is fitted into the hollow space of the hollow winding core attachment, in particular in a region at and / or in the vicinity of the first end of the winding core attachment. As a result, the stability of the reel spool according to the invention, in particular during unwinding, can be stabilized.

In the settlement of the package, for example, a cable user, the winding material, in the exemplary case, a cable can be deducted from the stationary winding bobbin according to the invention, in which case the winding material or the cable can be deducted to last, without the stability of the container decreases and leads to problems in peeling. Preferably, the unwinding of the package according to the invention is carried out using an NPS unwinding device.

In a preferred embodiment, the shipping container is a cable bundle, preferably this is used for the production of wire harnesses for motor vehicles use.

If the disposable winding spool is used in a reusable system, the first flange can be removed at the end with the smaller diameter and the winding core attachments and the flanges stacked on each other in a space-saving manner for a return transport of the plastic reels according to the invention. Thus, only a small transport volume is needed for the return transport. In particular for the transport of the invention Winding bobbins may be stacked several of the first flanges and / or a plurality of the winding core attachments and / or a plurality of the winding bobbins in a developed and / or wound and / or transportable state. Alternatively, another carrier identical to a carrier coil, such as the known NPS coil, may be used.

Such an alternative carrier system or alternative carrier body can consist of an elongated body with a plurality of cylindrical or conical sections, which touch and support the hub in its interior in several places, in particular in areas at the first and second ends of the hub.

The solution according to the invention has a number of other advantages.

The first and the first two digits of a reference character indicate the respective figure itself.

1 and 2 show a first carrier system used for the NPS winding reels of the invention, in this case an NPS reusable rewinding system.

16 shows a second, alternative usable carrier system. It should be noted that other carrier systems with other carrier coils, such as steel coils, are usable.

1 shows the side view of the known NPS winding device with a NPS reusable coil according to the prior art EP 0 672 016 B1 , 2 a longitudinal section through the known NPS reusable spool according to the prior art EP 0 672 016 B1 ,

In the immediate following, first the carrier system will be described in more detail. The total with 100 designated NPS reusable winding device has a first coil receiving device 103 and a second coil receiving device 104 on. The (reusable) reel spool 50 , which is used as a support coil for the NPS disposable spools according to the invention, has a conical winding core 52 and a first flange 53 and a second flange 54 on.

The first flange 53 is disposed at the end of the winding core with a smaller diameter, the second flange 54 at the end of the winding core of larger diameter. The (carrier) winding coil is substantially rotationally symmetrical to the axis extending in its longitudinal direction 56 , The winding device is, as shown, preferably designed so that the coil longitudinal axis 56 is vertical, and the first flange 53 below and the second flange 54 are arranged above.

The coil holder 103 is also essentially rotationally symmetrical and is about an axis 106 rotatable. The coil receiving device has a circular base plate 108 on, on a support plate 109 is arranged with a smaller diameter. On the support plate 109 there is a cone 111 in a correspondingly designed hole 72 of the flange 53 the winding spool 50 intervenes. By this cone, the winding spool in relation to the coil receiving device 103 centered. Concentric to the coil receiving device 103 is a pulley 115 arranged, which has a drive belt 117 from a (unspecified) drive means 116 is driven.

The upper coil receiving device 104 has a plate 120 on which on a stamp 122 is attached. The plate is rotatable about an axis of rotation 123 stored, which with the axis 56 the winding spool and the axle 106 the lower coil receptacle coincides. The stamp is as indicated by the arrow 125 is indicated, raised and lowered, including unspecified piston-cylinder units 127 and 128 be used. The pistons 129 . 130 the piston-cylinder units are over a yoke 131 with the stamp 127 connected.

At the plate 120 is a ring pointing in the direction of the reel spool 112 molded, whose outer wall to the plate 120 is inclined, wherein the angle to the Konizitätswinkel the winding bobbin 50 equivalent. A second ring 113 is on the outer circumference of the plate 120 molded and also points down to the reel spool.

The winding device further comprises a laying device 140 on that with a laying roller 142 is provided, via which the wire or the cable D is guided to the reel spool. The laying roller 142 is like the double arrow 143 is indicated, in a direction parallel to the winding bobbin axis 56 raised and lowered. For this purpose, the laying device has a threaded spindle extending parallel to the longitudinal axis of the reel spool 144 on, which via a drive device 145 is rotatable in both directions. Depending on the direction of rotation of the laying device while the laying roller is raised, that is in the direction of the drive device 145 moved or lowered again.

The function of the winding device is controlled by a (not shown) control device. The controller receives signals from sensors indicative of the angular velocity of the coil and signals indicative of the position of the laying roller 142 Show.

Based on these signals, the drive device 116 and the drive device 145 controlled so that during the winding process on the spool 50 - Or in the cases of the execution uses as a carrier system on the NPS disposable coil - the desired winding image results.

The function of this device will now be described, which applies equally to the device used as a carrier system for the NPS disposable coils according to the invention:
By a stroke movement of the piston-cylinder units 127 and 128 becomes the stamp 122 and thus the coil receiving device 104 raised. A reel spool is manually or by an automatic device on the coil recording 103 put on, with the cone 111 the coil receptacle engages in the opening of the reel spool, and this centered.

Subsequently, the stamp 122 with the coil holder 104 lowered until it rests on the upper end of the coil. This centers the conical ring 112 the upper end of the larger diameter hub and the ring 113 the coil mount supports the flange 54 from the coil.

The wire end is then at the lower flange 53 set, for example, by an automatic device and the Verlegerolle set in rotation to wind the wire or the cable. In this case, the control of the drive device happens 116 and the drive device 145 Preferably, so that there is a winding image, as shown in the EP-B-0 334 211 , see there in particular the 1 . 2 and 4 as well as the corresponding description.

During the winding process, the lower flange 53 through the support plate 109 and the upper flange 54 through the plate 120 the coil recording 104 or through the ring 113 supported. As a result, the flanges can not be deformed by the winding pressure and the weight of the winding material. However, not only the axial forces but also the radial forces acting in the winding reel are absorbed by the design. In the area of the lower coil intake 103 this happens through the cone 111 , which is the lower flange 53 supported over a large area. Since the flange, as will be apparent from the description, can be provided with corresponding reinforcing ribs, this support is sufficient to avoid an inadmissible deformation of the flange despite its low weight.

The upper end of the hub and the flange 54 be through the ring 112 and the ring 113 that attaches to a corresponding projection of the flange 54 supported, held pliers. This will allow both the radially inward as well the radially outward forces directly from the plate 120 taken and thus reliably prevents deformation of the winding core and the flange in this area.

Once the bobbin is fully wound, the wire is caught and cut, preferably by an automatic catching and cutting device, and the bobbin-side end is also preferably automatically fixed to the bobbin. Subsequently, the bobbin is removed and can be stacked and transported without further packaging measures.

The NPS reusable coil used as the support system for the NPS disposable reels of the present invention will now be described in relation to FIGS 2 described.

In the 2 represented (carrier) coil 50 consists of a conical hub 52 , a first flange 53 and a second flange 54 , The first flange 53 is removable and at the end 52a arranged the winding core whose diameter is smaller.

The second flange 54 is at the end 52b arranged the winding core with the larger diameter and is formed integrally with the winding core.

Overall, the coil is substantially rotationally symmetrical to the axis extending in its longitudinal direction 56 ,

At the second end of the flange, the fixed flange 54 , are reinforcing ribs 57 provided, which increase the strength and rigidity of the flange. Furthermore, there are a number of holes 59 arranged in the flange, which is perpendicular to the axis of rotation 56 run. The holes can be used for the use of hoists or for the attachment of drainage aids.

As in 2 can be seen, is the Konizitätswinkel the cylindrical saune of the hub 52 equal to the Konizitätswinkel the cylinder inner shell of the winding core 52 or, in other words, the shell of the winding core has a constant wall thickness between the two flanges.

Because the end with the larger diameter 52b the winding core is opened, thereby creating a conical cavity, which allows the stacking of the winding core.

The first removable flange 53 points as in 2 can be seen, a cylindrical shoulder which is rotationally symmetrical to an axis which, in the assembled state, with the axis of rotation 56 the hub coincides. The cylindrical shoulder is incorporated in the rotationally symmetrical flange plate. At her the winding core 52 opposite side are a plurality of concentric ribs, ie ribbed rings arranged.

winding core 52 and flange 53 are manufactured separately, preferably by injection molding of a suitable plastic material. winding core 52 and flange 53 are mounted and can then be wound in the usual use of the NPS reusable spool. Once the first turns of wire have been placed around the spool core, a firm positive connection between the hub is 52 and the removable flange 53 achieved, which increases the strength of the connection. This means that the thickness of the winding core shell and the geometric arrangement of the locking tongues can be selected so that an assembly and disassembly by hand is possible.

Additional security measures, such as a screw backup and the like., Are not required.

The assembly of the NPS reusable coil is carried out accordingly when recording the NPS disposable reels according to the execution as well as their removal from the NPS reusable coil as a support coil.

Two NPS disposable coils are described below 3 to 6 . 8th to 10 such as 7 and 11 shown, which differ in their closure system for mounting detachable flange and hub assembly.

3 shows a longitudinal section through an NPS disposable coil 300 mounted on an above-described NPS reusable coil 1 . 3 respectively. 50 as a carrier system. In the 3 illustrated NPS disposable coil 300 consists of a conical hub 301 , a first flange 303 and a second flange 302 , The first flange 303 is removable and at the end 303a arranged the winding core, whose diameter is smaller.

The second flange 302 is at the end 302b arranged the winding core with the larger diameter and is integral with the winding core attachment 301 educated. The disposable coil 300 is generally rotationally symmetrical to the axis extending in its longitudinal direction 305 ,

In one end area 303b of the winding core attachment 301 with the smaller diameter are as well 4 . 5 . 6 and 10 show one Number of openings 311 . 411 . 511 . 611 and 1011 , so-called latching openings, provided in the winding core attachment, each having the same distance from each other, in a plane perpendicular to the axis of rotation 305 of the winding core attachment 301 lie and in which Segmentastungen 312 . 412 . 912 . 1012 of the first flange 303 intervention.

The shape or arrangement of the detent openings 311 is according to the segment catches 312 manufactured, so that an easy to reach engagement of Segmentrastung 312 in detent opening 311 can achieve. The engagement simultaneously prevents twisting of the removable flange 303 opposite the winding core attachment 301 ,

At the end 303a of the winding core attachment 301 with the smaller diameter is as well 6 and 10 show one inwards on the axis of rotation 305 directed Rundumrastung 313 arranged, which engages with an oppositely directed Rundumrastung the releasable flange 303 stands. At the second end of the flange, the fixed flange 302 , are circular reinforcing ribs 422 and star-shaped reinforcing ribs 420 provided, which increase the strength and rigidity of the flange.

Furthermore, there are a number of holes 421 , so-called carrying eyes, arranged in the flange, which are perpendicular to the axis of rotation 305 run. The holes or carrying eyelets 421 can be used for the use of hoists or for the attachment of drainage aids.

As in 3 can be seen, both have flanges 302 . 303 a conical shape, ie the flanges are in the direction away from the axis of rotation 305 thinner and widening around the widening angles b1 and b2. As a result, the flange pressure is reduced while the winding width remains the same, since a small valley is created on the flange as a result of the winding process.

As in further 3 can be seen, is the Konizitätswinkel the cylinder outer shell 301 substantially equal to the taper angle of the cylinder inner shell 301b or, in other words, the jacket of the hub 301 has an approximately constant wall thickness between the two flanges.

Furthermore, the angle of conicity of the jacket of the winding core attachment substantially coincides with the conicity angle of the winding core of the carrier coil, whereby a frictional engagement is achieved, at least in partial areas between the winding core attachment of the one-way coil and the winding core of the carrier coil. Intermediate cavities can be filled by soft materials.

Because the end 302b is opened with the larger diameter of the winding core, this creates a conical cavity, which allows the stacking of the winding core. The first removable flange 303 points, as well as in the 4 . 9 and 10 can be seen, a cone-shaped approach 320 . 920 on, which is rotationally symmetrical to an axis, which, in the assembled state, with the axis of rotation 305 of the winding core attachment coincides.

The cone-shaped approach 320 has inwardly directed latching projections or segment catchings 312 . 412 . 912 . 1012 on, whose locking surfaces substantially perpendicular to the cylinder axis 305 run, this conical approach 320 for mounting the winding core attachment 301 is turned. The segment snaps 312 stand in the assembled state with the detent openings 311 of the winding core attachment 301 engaged. The cone-shaped approach 320 is integral with the rotationally symmetrical flange plate 321 connected. At her the winding core tower 301 opposite side are like 8th and 9 show concentric ribs arranged, which have an inner ribbed ring 833 and an outer rib ring 831 form. Inside the inner rib ring 833 are star-shaped ribs 830 intended.

Next, the first, removable flange 303 a pull tab 840 on, which serves to open the Rundumrastung. As in 10 It can be seen, the latching interventions by Rundumrastung 1013 and wrap around 1014 as well as segment snap 1012 and detent opening 1011 be configured such that distances x 1090 and y 1091 be formed.

Preferably, the distances x and y can be dimensioned such that the distance x 1090 less than the distance y 1091 is. In this case, both catchings, which distribute forces more evenly and smaller wall thicknesses can be realized.

The function of this disposable coil is according to the reusable winding spool as follows:
Hub cap 301 and flange 303 are manufactured separately from each other, preferably by injection molding of a suitable plastic material, in particular PE and PP.

To mount the coil is the flange 302 placed on a flat surface and the end 302a of the winding core attachment on the conical approach 320 pressed. The segment snaps 312 of the flange 303 snap into the detent openings 311 of the winding core attachment 301 one. The assembly of the disposable coil is completed.

The assembled disposable coil is placed on an unassembled reusable spool, which is then mounted as described above and used as described - but in this case as a carrier of the disposable coil - in the winding device. The wrapping of the disposable coil can be started.

Once the first turns of wire around the hub 301 are the segment notches 312 prevented from moving to the outside. This is a solid positive connection between the hub 301 and the removable flange 303 reached.

As in 3 to recognize is a plate 350 provided for opening the reusable coil. The plate 350 has according to the number and arrangement of the ribs in the flange arranged on its surface driving pins 352 on which are in a corresponding engagement with recesses of the flange.

Next, the plate has a centering 351 which is in engagement with a corresponding recess 354 in the flange 3 the reusable coil can be brought. Furthermore, the plate has 350 a free spin 353 for the latch to open.

In the 7 and 11 is in the representation accordingly 6 and 10 An alternative closure system for mounting the detachable flange and hub assembly in an alternative NPS disposable coil 700 . 1100 shown. The alternative closure system according to the closure system described above, the Rundumrastung 1114 the removable flange 1103 and the engaged with this Rundumrastung 713 . 1113 of the winding core attachment 701 . 1101 on. However, the alternative closure system dispenses with the segment detents and the associated detent openings.

As in 14 The wound coils, in this case two wound coils, can be shown 1400a . 1400b to be placed directly on each other. The first, removable flange is supported 1403a the first wound NPS disposable coil 1400a directly on the second, fixed flange 1402b the second NPS disposable coil 1400b from. The second, fixed flange engages 1402b such in recesses of the first, removable flange 1403a one that the winding spools 1400a . 1400b be centered against each other and also a slipping of the coils against each other is not possible.

Due to the design according to the invention, only partially filled coils can be transported and stored. In the 12 and 13 It is shown how advantageous the transport possibilities of the winding reel according to the invention, in this case as an empty reel, are.

For transport, an NPS coil is mounted. The other coils to be transported are dismantled. Their winding core attachments will be like 13 shows stacked upwards; their removed flanges are correspondingly 13 stacked down. A set of corresponding winding core attachments can then be stacked on lower winding core attachments set up in such a way, with the winding core attachments each resting on one another with the lower end of the fixed flange.

As a result, a small air gap can form between the stacked winding core attachments, which minimizes the adhesion forces between the stacked winding core attachments, so that the winding core attachments can be easily separated from one another. Such stacked core attachments can, as 13 shows, for transport on stacked, dissolved flanges are placed.

In 12 is shown as the removable flanges 1203 be stacked. Like in the 12 can be seen, engage in the stacking the Segmentrastungen 1212 a lower flange in the stacking openings 1215 of the upper flange. As a result, the flanges can not only be stacked on each other to save space; it also prevents slippage of the flanges against each other.

15 shows on a transport pallet 1570 stacked, filled winding spools 1500 , Due to the design according to the invention, only partially filled reel spools can be transported and stored.

In 16 is an alternative carrier system 1600 for the NPS disposable coil 1601 shown. This alternative carrier system has the same function as the NPS reusable system 1600 has an elongated, cylindrical body 1605 on. A first, upper end 1602a this cylindrical body 1605 has a flange 1602b on which a rotationally symmetrical, cone-shaped attachment 1603 is screwed.

An outer diameter 1603a This rotationally symmetrical, cone-shaped attachment 1603 is dimensioned such that an outer wall 1603b of the essay 1603 the inner wall 1606a of the winding core attachment 1606 in the area of the winding core attachment 1606 with the fixed flange 1607 touched and thus supports this. A second, lower end 1608a this cylindrical body 1605 also has a flange 1608b on, with which a support plate or metal plate 1609 is screwed.

This rotationally symmetrical, flange-like carrier plate 1609 is correspondingly functionally identical to the above article 1603 designed so that an outer wall 1609a the carrier plate 1609 the wrap around 1610a of the winding core attachment 1606 at the end with the removable flange 1611 touched and thus supports this.

The carrier plate 1609 is designed like a disk at one end. A surface formed thereby 1612 supports the (mounted) removable flange 1611 at its bottom 1611 from. In order to prevent twisting of the mounted winding spool in the carrier system, a pin 1613 be attached.

17 shows one on a mobile transport system 1710 mounted NPS disposable coil 1701 , in which by the hollow hub 1702 formed cavity 1703 a weight or weight element 1704 is fitted in the form of a rotationally symmetric, cone-shaped body. As 17 shows is the weight 1704 in the cavity 1703 the hollow hub core 1702 in an area at and / or near the first end 1705 of the winding core attachment 1702 fitted. To facilitate the handling or assembly of the weight element 1704 this one has a handle 1711 on. Through this fitted weight 1704 For example, the stability of the NPS disposable coil, especially during unwinding, can be stabilized.

18 shows a half-section of a winding bobbin according to the invention. This winding spool 1800 has a first flange 1802 and a second flange 1803 on, these two flanges stand over a hollow, conical section 1801 in contact with each other. The hollow, conical section 1801 has a longitudinal extent l between these two flanges. Next has the hollow, conical section 1801 an average wall thickness t. The aspect ratio l / t is based on the hollow, conical section on the modulus of elasticity of the material used. The slenderness ratio l / t according to the invention achieves on the one hand a rigid design of the winding bobbin, by means of which, on the other hand, a large amount of elongate winding material can be accommodated. Characterized in that the winding bobbin according to the invention (not shown) can be placed on a support coil, is an interface of the inner contour of the hollow, conical section 1801 given, a larger wall thickness of the hollow, conical section thus inevitably leads to an undesirable reduction of the recordable winding volume.

19 shows a portion of the hollow conical section 1901 with a pocket-like recess 1901c , which is shown for latching with a latching engagement (not shown) of the releasable flange (not shown) for clarity in the unlocked state. The hollow conical section 1901 indicates the mean wall thickness t in this area. The pocket-like recess 1901c has a reduction of the wall thickness t by the dimension k2. In this case, this recess 1901c from the inner surface 1901e of the hollow, conical section offset radially outward by the dimension k2. The recess is further by the dimension k1 from the end face 1901d the hollow, conical section 1901 discontinued in the axial direction. In this case, the dimensions k1 and k2 are based on the latching engagement (not shown), which is used for latching with this recess 1901c is provided.

20 shows a detachable flange 2003 , which with the hollow, conical section 2001 is locked. Here is the pocket-like recess 2001c in the hollow, conical section 2001 with the measures k1 and k2 so to the locking engagement 2013 adapted to both the frontal surface 2001d , as well as on the inner surface 2001e of the hollow, conical section, a continuous course of the area without substantial steps, jumps or the like results.

The pocket-like recess is by the amount k2 of the inner surface 2001e discontinued, wherein the measure k2 is substantially the wall thickness of the latching engagement 2013 in this area corresponds. As a result of this adaptation in this area, the wall thickness t is retained overall, resulting in a continuous surface course in the area of the inner surface 2001e , Next, the pocket-like recess by the dimension k1 of the end face 2001d discontinued, wherein the measure k1 substantially the wall thickness of the latching engagement 2013 in this area, also here there is a continuous surface course in the area of the end face 2001d , The hollow conical section also has further detent openings 2011 on, in which further locking engagements (not shown) of the releasable flange 2003 can intervene.
