Description

Winding bobbin for a container and method for its

Production and processing

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

The invention furthermore 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 elongated winding material using a winding bobbin according to the invention and a container for a transportable winding material. The invention is suitable for all elongate winding material, which is usually wound on (wickel-) coils.

European patent EP-B-0 334 211 discloses a process for the production of an unpackaged transportable package using a collapsible steel coil on which a sleeve made of gray cardboard or corrugated cardboard is placed. Both the steel coil and the cardboard sleeve have a conically shaped winding core. The winding of the coil begins at the end of the winding core, which has the smaller diameter, and is carried out with a moving parallel to the longitudinal axis of the coil laying device such that the length of the winding layers, in the longitudinal direction. Direction of the coil seen is increased substantially continuously, so that there is a so-called doppelkonischer structure of the winding.

The withdrawal of the cable from this container is usually carried out by the stationary coil and with a vertically oriented longitudinal axis, whereby here too the winding core with the smaller diameter is arranged 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 container capable of being shipped is described in EP 0 504 503 B1. This shipping system uses a conical core made of plastic with a flange at the end of larger diameter. 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 container which can be shipped, EP 0 672 016 B2 has disclosed a method in which a specially designed winding spool made of plastic is used. it becomes. The winding spool, which is shown in Fig. 2, is conical and has at its end with a smaller diameter on a special locking system connected to 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 shown in FIG. 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 context, 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 stacked hub and flanges to save space. 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. In this case, since the cycle time of a coil, that is, the time that elapses until the coil has arrived at the cable manufacturer from the cable manufacturer and processed and transported back there, is so high that an extremely high number of reel spools would be required.

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, a winding bobbin for receiving an elongate winding material and a method for its production and for the development of the Wickleguts has become known. In this winding coil, a part of a plastic low strength, which is recyclable. Next is a hollow tapered portion of this coil as designed thin-walled section, in particular, the portion for receiving the winding material is designed as a flexible plastic skin.

The present invention is therefore based on the object of providing a winding bobbin for a container which can be shipped, a method for producing and unwinding a container which can be shipped, and a container with which an economic and reliable transport system can be realized. 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 solved according to independent claim.

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 slenderness ratio of the wall of this conical section is chosen as a function of material characteristics of this plastic, in particular chosen so 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 reel. Conventional winding spools are in direct contact with a winding spool receiving device of a winding device and have higher strength and in particular higher rigidity than the winding core top 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 spool - with at least a first flange, which is detachably arranged at the first end of the winding core and with at least one second flange, which is arranged at the second end of the winding core. The conical, hollow portion of the winding core attachment, which is arranged between the two flanges, has a thin-walled design with a length I (extension between the two flanges) and an average wall thickness t. Further, this hollow conical portion has as an essential component or preferably consists of it, a plastic having a modulus of elasticity (modulus of elasticity) in the range of 1000 N / mm ² to 30 000 N / mm ² . Within the meaning of the invention is an essential part Also to understand a matrix material of a fiber composite material, even if the fiber content 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 characteristic values (modulus of elasticity) of this section results in the form of a material in the design of the winding coil according to the invention other modulus of elasticity, 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 assembled is placed on the carrier system, for example a known, divisible winding bobbin, such as the divisible winding bobbin known from EP 0 672 016 B2 (FIG. 2).

The carrier system or the carrier coil, together with the winding bobbin according to the invention placed on it, is converted into a winding device known from EP 0 672 016 B2 for wrapping the carrier system, for example the known, divisible winding bobbin, suitable winding device (FIG 1). 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 accommodated in the winding device as is known - with the invention according to the difference that in this case the carrier coil carries the winding bobbin according to the invention (as an attachment 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 from EP 0 672 016 B1, controlled by a control device is that results in 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 applied 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

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 diameter larger than the first end, wherein a cavity of the winding core attachment is conical and open on both sides,

- 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:

Inserting the wound reel into a winding device, 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, as known for example from EP 0 672 016 B1, as a carrier or another functionally identical carrier body as a carrier system for a lower cost to be produced, to be wound disposable reel with sufficient Provide 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".

The use of disposable spools, the section between the two flanges as an essential part of a plastic has o- which consists of such, shown that it can lead to irregularities in the handling of this, ie in the winding, handling, storage the transport or the like. This is to be understood in particular as meaning that the position of the elongate winding material on the reel spool can change, so that in the worst case it is no longer possible to completely unwind the winding material from the reel. 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, there may thus be 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 completely applied to the hub again, since 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, koni see 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. Furthermore, for winding bobbins in different sizes but sometimes also for winding coils of the same geometry, different materials used 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 secure unwinding is possible on the one hand and that the volume of rewindable material to be taken up by the reel spool is as large as possible under this condition.

Furthermore, the advantage of these disposable winding bobbins 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 During the unwinding of the reel spool according to the invention, a carrier system or support body, such as a carrier reel, is not or not absolutely necessary, as in the rewinding.

By the possible by the invention resorting to the known winding system, for example, the well-known N PS winding system, can also use its advantageous features. Thus, in the case of the wound bobbin according to the invention, the same winding patterns as in the N PS 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 N PS 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 coil, such as the known N PS 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. Thus, in the invention, the advantages of a container, as has become known from EP-B-0 334 21 1, can be combined with the advantages of a container, such as that from EP 0 672 016 B1.

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." The invention also has the advantage that no strapping is necessary in the case of the filled winding coils.

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. If higher strength requirements or higher stiffness requirements are to be met, the plastic can be reinforced by suitable means, for example 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 an essential part PP, or consists of this. Further preferably, the reverse combination of the materials described above is possible. By using 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 production 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 material is not designed as a plastic skin, in particular in the area of the hollow, conical section of the reel spool, but rather with a significant average wall thickness t, so that a deformation of this section is possible radially inward. ter the force effects occurring in the handling of the reel spool is reduced or avoided 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. Due to the low weight and the relatively simple structure of the hub core can be made very inexpensive, so that the cost of "lost" disposable winding coils, ie the erfindungsge- The winding spools are used once and are not significant for the cable manufacturer.

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.

On the other hand, it has been shown that gray cardboard and / or corrugated cardboard cause problems in countries with hot and / or humid climates, since gray cardboard absorbs water and then warps or swells or shrinks depending on the prevailing atmospheric humidity. Seraufnahme also disintegrates. 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 separable plastic coils as support coils for the reel spool according to the invention has the advantage that the weight of the total coil device introduced into the winding device, i. the carrier coil with the attached winding bobbin according to the invention is still relatively low. Thus, the imbalances resulting from unavoidable deviations in diameter are relatively small even at a high rotational speed of the carrier coil.

This means a significant 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 detents, 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, to be received in the locked state so that a continuous surface course is formed, in particular therefore the inner surface of the hollow, conical portion and a frontal area of this portion substantially continuous Have history, in particular are not disturbed by steps, heels 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 reichswese or completely, and designed as a pocket-like recesses latching portion of the hollow, conical section, in each case in about 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 thereby be placed particularly well on a support coil, in particular so that only a small or no cavity hiss the hollow, conical section and the support coil is formed, as this can occur when the surface course 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 detachable flange, a lifting lug for use with a hoist and / or a handle with a pull tab for a separation of the at least one flange from the winding core attachment (cone part) may be provided. 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.

The winding bobbin according to the invention is preferably applied to a carrier bobbin and introduced into a winding device such that the inventive The winding coil according to the invention is arranged in a vertical arrangement of the coil axis with the smaller diameter of the winding core support facing downwards in the winding device and, according to known winding methods, is provided with a double conical winding.

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 N PS 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 winding bobbins according to the invention, a plurality of the first flanges and / or a plurality of the winding core attachments and / or a plurality of the winding bobbins can be stacked 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 winding bobbin or winding core attachment according to the invention is designed such that it can be received by a conventional, divisible winding bobbin, as described in the European patent EP 0 672 016, during the winding process.

Since such winding bobbins are available in large numbers for the cable manufacturer, he does not have to spend any additional costs in order to be able to machine the winding bobbins according to the invention. In particular, he can winding coils according to the invention with the same machines with which he wound the coils for the conventional NPS system.

EMBODIMENTS NPS Disposable Coils (with N PS Reusable Reel System as a Carrier System or an Alternative Carrier System) Embodiments of the NPS Disposable Coil Nose, short NPS Disposable Coil, will be described below with reference to Figs.

The reference numerals of Figures 3 to 20 are constructed such that the last two digits of the respective reference numeral name a part or component to be designated. Thus, the same parts or components (also) in different figures on the same last two digits.

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

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

Figure 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 an NPS reusable coil according to the prior art EP 0 672 016 B1. 2 shows a longitudinal section through the known NPS reusable coil 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 generally designated 100 NPS reusable winding device has a first coil receiving device 103 and a second coil receiving device 104. The (reusable) reel spool 50, which is used as a support spool for the NPS disposable reels according to the invention, has a conical winding core 52 and a first flange 53 and a second flange 54.

The first flange 53 is disposed at the end of the smaller diameter winding core, the second flange 54 at the end of the larger diameter winding core. The (carrier) winding bobbin is substantially rotationally symmetrical to the axis 56 running in its longitudinal direction. As shown, the winding device is preferably designed such that the bobbin longitudinal axis 56 is vertical, and the first flange 53 at the bottom and the second flange 54 at the top are.

The coil receptacle 103 is also designed substantially rotationally symmetrical and is rotatable about an axis 106. The coil receiving device has a circular base plate 108, on which a support plate 109 is arranged with a smaller diameter. On the support plate 109 is a cone 1 11, which engages in a correspondingly shaped bore 72 of the flange 53 of the reel spool 50. By this cone, the winding spool is centered with respect to the spool receiving device 103. Concentric with the coil receiving device 103, a pulley 1 15 is arranged, which is driven by a drive belt 1 17 (not explained in more detail) drive means 16. The upper coil receiving device 104 has a plate 120 which is fixed to a punch 122. The plate is rotatably supported about an axis of rotation 123 which coincides with the axis 56 of the reel spool and the axis 106 of the lower reel base. The punch is, as indicated by the arrow 125, raised and lowered, for which unspecified piston-cylinder units 127 and 128 are used. The pistons 129, 130 of the piston-cylinder units are connected via a yoke 131 with the plunger 127.

On the plate 120, a pointing in the direction of the winding coil ring 1 12 is formed, whose outer wall is inclined to the plate 120, wherein the angle corresponds to the Konizitätswinkel the winding spool 50. A second ring 1 13 is formed on the outer periphery of the plate 120 and also faces down to the reel spool. The winding device further comprises a laying device 140, which is provided with a Verlegerolle 142, via which the wire or the cable D is guided to the reel spool. The laying roller 142 is, as indicated by the double arrow 143, in a direction parallel to the winding spool axis 56 can be raised and lowered. For this purpose, the laying device has a threaded spindle 144 which extends parallel to the longitudinal axis of the reel spool and which is rotatable in both directions via a drive device 145. Depending on the direction of rotation of the laying device while the laying roller is raised, that is moved in the direction of the drive means 145 and 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 respective position of the laying roller 142. Based on these signals, the drive means 1 16 and the drive means 145 are controlled so that during the winding process on the Coil 50 - or in the cases of the execution uses as a support 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 lifting movement of the piston-cylinder units 127 and 128 of the punch 122 and thus the coil receiving device 104 is raised. A reel spool is placed manually or by an automatically operating device on the reel seat 103, wherein the cone 1 1 1 of the reel seat engages in the opening of the reel spool, and this centered.

Subsequently, the punch 122 is lowered with the coil receptacle 104 until it rests on the upper end of the coil. In this case, the conical ring 1 12 centers the upper end of the winding core with the larger diameter and the ring 1 13 of the coil receiving supports the flange 54 of the coil.

The wire end is then secured to the lower flange 53, for example, by an automatically operating device and the Verlegerolle set in rotation to wind the wire or the cable. In this case, the control of the drive device 16 and the drive device 145 preferably takes place such that a winding pattern results, as described in EP-B-0 334 21 1, see in particular FIGS. 1, 2 and 4 and the associated description, results. During the winding process, the lower flange 53 is supported by the support plate 109 and the upper flange 54 by the plate 120 of the coil receptacle 104 and by the ring 1 13. As a result, the flanges can not be deformed by the winding pressure and the weight of the winding material. The design not only absorbs the axial forces, but also the radial forces acting in the winding reel. In the region of the lower coil receiving 103 this is done by the cone 1 1 1, which supports the lower flange 53 over a large area. As the flange, as is clear from the description still results, can be provided with appropriate reinforcing ribs, this support is sufficient to avoid an inadmissible deformation of the flange despite its low weight. The upper end of the winding core and the flange 54 are held by the ring 1 12 and the ring 1 13, which is supported on a corresponding projection of the flange 54, pliers. As a result, both the forces acting radially inwards and radially outward are absorbed directly by the plate 120 and thus reliably prevent deformation of the winding core and of 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 a support system for the NPS disposable reels of the invention will now be described with reference to FIG.

The (support) coil 50 shown in Fig. 2 consists of a conical winding core 52, a first flange 53 and a second flange 54. The first flange 53 is detachable and arranged at the end 52a of the winding core, whose diameter is smaller.

The second flange 54 is arranged at the end 52b of the winding core with the larger diameter and is formed integrally with the winding core. Overall, the coil is substantially rotationally symmetrical with respect to the axis 56 extending in its longitudinal direction.

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

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

Since the end is opened with the larger diameter 52b of the winding core, thereby creating a conical cavity, which allows the stacking of the winding core. As can be seen in FIG. 2, the first removable flange 53 has a cylindrical shoulder which is rotationally symmetrical about an axis which, when mounted, coincides with the axis of rotation 56 of the winding core. The cylindrical shoulder is incorporated in the rotationally symmetrical flange plate. On its side facing away from the winding core 52 are several concentric see ribs, i. 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 assembled and can then be wound in the usual use of NPS reusable spool. Once the first turns of wire have been placed around the spool core, a tight positive connection between the winding core 52 and the removable flange 53 is 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 spools according to the embodiment are shown below with reference to FIGS. 3 to 6, 8 to 10 and 7 and 11, which differ in their closure system for mounting detachable flange and winding core attachment.

Fig. 3 shows a longitudinal section through an NPS disposable coil 300 mounted on a NPS reusable coil 1, 3 and 50 described above as a carrier system. The NPS disposable reel 300 shown in Fig. 3 consists of a conical core 301, a first flange 303 and a second flange 302. The first flange 303 is detachable and disposed at the end 303a of the core hub whose diameter is smaller. The second flange 302 is arranged at the end 302b of the winding core attachment with the larger diameter and is formed integrally with the corrugation core 301. The one-way spool 300 is generally rotationally symmetrical about the axis 305 extending in its longitudinal direction. In an end portion 303b of the smaller-diameter spool core 301, as well as Figs. 4, 5, 6 and 10, there are a number of apertures 31 1, 41, 51 1, 61 1 and 101 1, so-called detent openings, provided in the winding core, each having the same distance from each other, in a plane perpendicular to the axis of rotation 305 of the Wickelkernaufsat- are 301 and into which Segmentastungen 312, 412 , 912, 1012 of the first flange 303 engage. The shape or arrangement of the detent openings 31 1 is made according to the segment detents 312, so that an easy-to-reach engagement of the segment detent 312 in the detent opening 311 can be achieved. The engagement simultaneously prevents twisting of the removable flange 303 relative to the winding core attachment 301.

At the end 303a of the smaller diameter winding core bit 301, as well as Fig. 6 and Fig. 10, there is a circumferential catch 313 directed inwardly on the axis of rotation 305, which engages with an oppositely directed circumferential catch of the releasable flange 303. At the second flange end, the fixed flange 302, circular reinforcing ribs 422 and star-shaped reinforcing ribs 420 are provided, which increase the strength and rigidity of the flange. Furthermore, a number of holes 421, so-called carrying eyelets, arranged in the flange, which extend perpendicular to the axis of rotation 305. The holes or eyelets 421 can be used for the use of lifting equipment or for the attachment of drainage aids. As can be seen in Fig. 3, both flanges 302, 303 have a conical shape, i. the flanges become thinner in the direction away from the rotation axis 305 and widen by the flare 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 can further be seen in FIG. 3, the angle of conicity of the outer cylinder jacket 301a is substantially equal to the conicity angle of the cylinder inner jacket 301b or, in other words, the jacket of the winding core attachment 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.

Since 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 detachable flange 303 has, as can also be seen in FIGS. 4, 9 and 10, a conical projection 320, 920 which is rotationally symmetrical about an axis which, when mounted, coincides with the axis of rotation 305 of the hub.

The conical projection 320 has inwardly directed latching projections or segment detents 312, 412, 912, 1012, the latching surfaces of which extend essentially perpendicular to the cylinder axis 305, this conical projection 320 facing the winding core attachment 301 for assembly. The segment detents 312 are in the mounted state with the detent openings 31 1 of the winding core 301 in engagement. The conical projection 320 is integrally connected to the rotationally symmetrical flange plate 321. On its side facing away from the winding core attachment 301, concentric ribs are arranged, like FIG. 8 and FIG. 9, which form an inner rib ring 833 and an outer rib ring 831. Inside the inner rib ring 833 star-shaped ribs 830 are provided.

Further, the first, removable flange 303 has a tear tab 840 which serves to open the Rundumrastung. As can be seen in FIG. 10, the locking engagements of all-round detent 1013 and all-round detent 1014 as well as segment detent 1012 and detent opening 101 1 can be designed such that spacings x 1090 and y 1091 are formed. Preferably, the distances x and y can be dimensioned such that the distance x 1090 is smaller than the distance y 1091. 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:

The winding core attachment 301 and the flange 303 are manufactured separately from each other, preferably by injection molding from each of a suitable Kunststoffmate- material, in particular PE and PP.

To mount the spool, the flange 302 is placed on a flat surface and the end 302 a of the winding core attachment is pressed onto the conical projection 320. The segment detents 312 of the flange 303 snap into the latching openings 31 1 of the winding core attachment 301. 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.

As soon as the first turns of wire have been placed around the winding core attachment 301, the segment detents 312 are prevented from moving outward. Thus, a fixed positive connection between the winding core 301 and the removable flange 303 is achieved.

As can be seen in Fig. 3, a plate 350 is provided for opening the reusable coil. The plate 350 has according to the number and arrangement of the ribs in the flange on its surface arranged driving pins 352, which are in a corresponding engagement with recesses of the flange. Further, the plate has a centering 351 which can be brought into engagement with a corresponding recess 354 in the flange 3 of the reusable coil. Further, the plate 350 has a free rotation 353 for the opening to be opened.

FIGS. 7 and 11 illustrate in the illustration corresponding to FIGS. 6 and 10 an alternative closure system for mounting a releasable flange and winding core attachment in an alternative NPS disposable coil 700, 1100. The alternative closure system has according to the closure system described above, the Rundumrastung 1 1 14 of the removable flange 1103 and with this engaging Rundumrastung 713, 1 1 13 of the winding core attachment 701, 1 101 on. However, the alternative closure system dispenses with the segment detents and the associated detent openings.

As shown in Fig. 14, the wound coils, in this case two wound coils 1400a, 1400b, can be placed directly on top of each other. At this time, the first detachable flange 1403a of the first wound NPS disposable coil 1400a is supported directly on the second fixed flange 1402b of the second disposable NPS coil 1400b. In this case, the second, fixed flange 1402b engages in recesses of the first, removable flange 1403a in such a way that the winding reels 1400a, 1400b are centered relative to one another and, moreover, that the coils do not slip against one another. Due to the design according to the invention, only partially filled coils can be transported and stored. FIGS. 2 and 13 show 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 are stacked as shown in FIG. 13; their removed flanges are correspondingly Figure 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 cores can, as shown in FIG. 13, be placed on stacked, detached flanges for transport.

In Fig. 12 is shown how the removable flanges 1203 are stacked. As can be seen in FIG. 12, when stacked, the lower grille segment detents 1212 engage the upper flange stack apertures 1215. 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. Fig. 15 shows on a transport pallet 1570 stacked, filled reel spools 1500. Due to the design according to the invention, only partially filled reel spools can be transported and stored.

FIG. 16 shows an alternative carrier system 1600 for the disposable NPS coil 1601. This alternative carrier system 1600, which is functionally identical to the PS reusable system, has an elongated, cylindrical body 1605. A first, upper end 1602a of this cylindrical body 1605 has a flange 1602b, to which a rotationally symmetrical, cone-shaped attachment 1603 is screwed.

An outer diameter 1603 a of this rotationally symmetrical, conical appendix 1603 is dimensioned such that an outer wall 1603 b of the superimposed zes 1603 the inner wall 1606a of the winding core attachment 1606 in the region of the winding core attachment 1606 touches the fixed flange 1607 and thereby supports this. A second, lower end 1608a of this cylindrical body 1605 also has a flange 1608b with which a support plate or metal plate 1609 is screwed.

This rotationally symmetrical, flange-like carrier plate 1609 is correspondingly configured functionally the above essay 1603, so that an outer wall 1609a of the support plate 1609 touches the Rundumrastung 1610a of Wickelkernaufsat- zes 1606 at the end with the removable flange 1611 and thereby supports this.

The support plate 1609 is disc-shaped at one end. A thus formed surface 1612 supports the (mounted) removable flange 161 1 on its underside 161 1 a from. In order to avoid twisting of the mounted reel spool in the carrier system, a pin 1613 can be attached.

17 shows a disposable NPS spool 1701 mounted on a movable transport system 1710, in the cavity 1703 of which is formed by the hollow winding core attachment 1702, a weight or weight element 1704 in the form of a rotationally symmetrical conical body is fitted. As shown in FIG. 17, the weight 1704 is fitted into the cavity 1703 of the hollow hub core 1702 in an area at and / or near the first end 1705 of the hub core 1702. To facilitate the handling or assembly of the weight member 1704, this has a handle 171 1. By means of this fitted weight 1704, the stability of the NPS disposable coil, in particular during unwinding, can be stabilized. Fig. 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, these two flanges are above a hollow conical section 1801 interconnected. The hollow conical section 1801 has a longitudinal extent I between these two flanges. Furthermore, the hollow conical section 1801 has 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 on a support coil (not shown) can be placed, an interface of the inner contour of the hollow conical section 1801 is given, a greater wall thickness of the hollow, conical section thus inevitably leads to an undesirable reduction of the recordable winding volume.

Fig. 9 shows a portion of the hollow conical portion 1901 with a pocket-like recess 1901c, which is shown for locking with a latching engagement (not shown) of the releasable flange (not shown) for clarity in the unlocked state. The hollow conical section 1901 has the average 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 1901 c is offset from the inner surface 1901e of the hollow, conical section radially outward by the dimension k2. The recess is further offset by the dimension k1 from the end face 1901d of the hollow conical section 1901 in the axial direction. In this case, the dimensions k1 and k2 are based on the latching engagement (not shown), which is provided for latching with this recess 1901c.

Fig. 20 shows a releasable flange 2003 which is locked to the hollow conical section 2001. In this case, the pocket-like recess 2001 c in the hollow conical section 2001 with the dimensions k1 and k2 adapted to the locking engagement 2013, that on both the end face 2001 d, and on the inner surface 2001 e of the hollow, conical section, a continuous surface course without significant paragraphs, jumps or the like results. The pocket-like recess is offset by the amount k2 of the inner surface 2001 e, wherein the measure k2 substantially corresponds to the wall thickness of the locking engagement 2013 in this area. Due to this adaptation in this area, the wall thickness t is retained overall, resulting in a continuous surface course in the area of interior area 2001 e. Next, the pocket-like recess is offset by the dimension k1 of the end face 2001 d, wherein the measure k1 substantially corresponds to the wall thickness of the locking engagement 2013 in this area, also here results in a continuous surface course in the area of the face 2001 d. The hollow conical section also has further latching openings 201 1, into which further latching engagements (not shown) of the detachable flange 2003 can engage.
