Description

The invention relates to a braiding device for braiding an endless core structure, preferably an annular core structure for forming a rim of an impeller of a bicycle, having a through-hole having a runner plate in which runner plate from one outside to the through hole extending gap for inserting the core structure introduced is, and with a plurality of impellers, which are provided for moving a plurality of clappers along two wave paths in the rotor plate, wherein each impeller, a drive gear is rotatably connected and wherein a first drive gear arranged on a first side of the gap, the first impeller and a second drive gear of a arranged on a second side of the gap second impeller in a common (first) toothing plane are arranged.

Such braiding devices are already known from the prior art. For example, the US 1,524,684 a device for braiding a coating on an object. This device has a holder which is adapted to guide a plurality of moving spool carriers against a central opening in this holder. Also, the apparatus comprises means for moving the carriers and a closed train of rotatable elements, the holder and said means for relative adjustment being provided to each other to open a portion of the holder without stopping said train. As further disclosed in this document, the respective drive gears, which are connected to the first and the second impeller, at least at a peripheral portion on a recess in the toothing region. Through this recess a core in the interior of the drive plate is feasible.

However, it has been found in these mainly used for the textile industry devices that they are less suitable for wrapping larger cores with modern materials, as is common, for example, in bicycles especially for rims. In today's mostly quite thick core structures, such as hollow core structures, it is hardly more possible to thread them through the constrictions, such as in the drive gears. For one thing, the risk of damage to the core structure during threading / insertion is relatively high, on the other hand, it may happen in the currently used, relatively brittle materials such as carbon fiber, aramid fiber, but also glass fiber, that this when unthreading / removal break the braided core structure.

It is therefore the object of the present invention to overcome the disadvantages known from the prior art and to provide a braiding device in which the risk of damage to an endless core structure or the completely wound core structure is to be reduced.

This object is achieved in that the toothing plane and the running plate are arranged spaced from each other in the axial direction, that the core structure at least partially inserted (within the running plate) in an operating state in a formed between the toothing plane and the running plate, axial gap is.

This makes it possible, when inserting the core structure into the running plate, to prevent the threading of the core structure through the drive gears. Consequently, in order to move the core structure in or out, these gears do not have to be provided separately with recesses or arranged to be displaceable relative to one another. As a result, the running plate in the operating principle is designed particularly simple, which is why the production costs of the braiding are significantly reduced. For threading the core structure (also referred to as a core or core braid) therefore simply the first and the second impeller must be positioned at standstill of the braiding in a special way to each other so that the gap, which is provided in the running plate anyway, is released and the core structure can be freely inserted with a portion in the interior of the drive plate and can be easily removed after braiding.

Further advantageous embodiments are claimed in the subclaims and explained in more detail below.

According to a further embodiment, the gap extends from the outside to the through hole in the radial direction inwards. As a result, the running plate is even cheaper to produce. In this connection, it is also advantageous if the first side of the gap (on which the first impeller is arranged) is one side of the gap in a first circumferential direction of the running plate and the second side (on which the second impeller is arranged) one side of the Gap in a second circumferential direction of the running plate, which is opposite to the first circumferential direction, is. Thus, the vanes are arranged along the circumference side by side, whereby the production of the running plate is simplified.

Furthermore, it is advantageous if the impellers are rotatably mounted on the drive plate, and the two wave paths of the drive plate are designed to extend continuously along the circumference. The two wave paths preferably run crossing each other along the circumference of the running plate. More preferably, each wave path extends substantially sinusoidally along the circumference around the running plate, wherein the two wave paths intersect at their turning points. Between two adjacent turning points / crossing points, an impeller is also rotatably mounted in the running plate in each case. As a result, the running plate is even cheaper to produce.

It is also advantageous if the first and the second drive gear mesh directly with each other in the operating state of the braiding device. As a result, the most direct connection / movement coupling of the first and second impellers is implemented.

If the vanes are distributed along the circumference and each with their drive gears with the drive gears of the two adjacent vanes are engaged, the drive of the vanes is implemented particularly effectively. Only a drive gear at a location along the circumference of The running plate is then driven by a drive device, such as a drive motor.

It is also advantageous if the first and the second impeller each have a flattening on their circumference, and are positioned in at least one rest position of the braiding (at standstill of the braiding device) such that the flats face each other, so that the core structure unhindered between the first and the second impeller and the gap is pushed past. Thereby, the first and the second impeller in a certain rotational position (in a rest position of the braiding device) are arranged as an open barrier, wherein the flats also form a gap which is at least as wide as the gap in the running plate. In the usual operating condition, during braiding of the core structure, the first and second impellers serve as an ordinary drive means. As a result, the threading / insertion and threading / removing the core structure is particularly easy.

If both wave paths are introduced into an axial end face of the running plate, an axial braider is configured particularly efficiently.

More preferably, the first impeller and / or the second impeller at least one holding mechanism for holding a clapper on. The holding mechanism is preferably designed as a magnet, but more preferably also as a click mechanism and particularly preferably as a clamping mechanism. As a result, the clappers in the rest position of the braiding device (when the braiding device is stationary) are held securely away from the gap of the running plate and are guided safely during transport in braiding in the vaned wheels. According to a further advantageous embodiment, the holding mechanism is mounted in the manner of the clamping mechanism, the click mechanism or the magnet in another impeller. Also, it is advantageous if the holding mechanism, in the form of one or more alternative / -r curved path / -en, is introduced into the running plate, the clapper in the rest position then in this / -n curve track / -en simple, again spaced from the Gap in the Running board, parked. Possibly. However, the clamping mechanism can also be omitted if the cam track / -en is designed / are such that the path of the bobbin at a certain speed by interaction of centrifugal force and the end of the cue on one side of the plate slides directly into the other half of the cam track.

It is also expedient if the gap has a width / gap width between 1 mm and 100 mm, more preferably between 20 mm and 40 mm. This makes it possible to braid even very large core structures, which are used in particular in the manufacture of bicycle rims, with the braiding device.

If the running plate is designed in several parts, preferably in two parts, with its running plate parts being displaceable relative to one another such that the gap can be enlarged and / or reduced by a relative movement of the running plate parts, particularly large cores can be wrapped by means of the braiding device. The versatility is thereby increased.

It is also expedient if a mold ring is present, which is rotatably connected to the drive plate and is also performed split at least a portion along the circumference. The molding ring, which is used, for example, for guiding and / or tensioning the braiding fibers, thus also has means for passing through the core structure. The molding ring is further preferably arranged on a side facing away from the drive gears of the drive plate. As a result, the mold ring is arbitrarily far away from the drive plate.

It is also advantageous if a connecting element is present on the running plate, which in the operating state is inserted into the running plate, closing the gap. As a result, a particularly large gap is formed.

In this context, it is also advantageous if the connecting element receives a non-rotatably connected to a connecting gear Verbindungsflügelrad, wherein the connecting gear in the operating state with the first and the second Drive gear meshes and the Verbindungsflügelrad between the first impeller and the second impeller, for forwarding the clapper between the first impeller and the second impeller, is arranged. As a result, the bridging of the gap in the operating state is particularly efficient.

Furthermore, the use of a previously described braiding device according to one of the previously described embodiments is also provided for braiding an endless core structure, such as a bicycle rim, wherein the following steps are included:

• a) positioning the bobbins spaced from the nip in the runner plate and releasing the nip by positioning the first and second impellers such that a portion of the core structure is radially freely slidable through the runner into the through-hole,
• c) inserting the section of the interwoven, endless core structure in the running plate, and
• d) braiding the core structure by a relative movement of the core structure and the running plate, so that a braided fiber layer is applied to the core structure by movement of the clapper along the at least one wave path by means of the impellers.

As a result, braiding the core structure is particularly simple and implemented with the least possible time.

The invention will now be explained in more detail with reference to figures, in which context also various embodiments are described.

The figures are merely schematic in nature and are for the sole purpose of understanding the invention. The same elements are provided with the same reference numerals. The features of the individual embodiments are freely combinable with each other.

In Fig. 1 the braiding device 1 according to the invention is shown particularly clearly in a first embodiment. The braiding device 1 is designed here as a braiding machine and serves for braiding an endless core structure 2. The braiding device 1 is also designed as a carbon fiber braiding device. The endless core structure 2 is here designed as an annular core / wicker core of a bicycle rim for an impeller of a bicycle. However, the core structure 2 does not have to be circular. In other embodiments, such as door frame profiles or the like in the automotive sector, also differently shaped core structures 2, such as elliptical or polygonal core structures 2 are formed. The endless core structure 1 is in Fig. 1 shown cut in the longitudinal direction. The core structure 2 is formed of a foam material. More preferably, the core structure 2 is formed as a hollow core, such as an inflatable tubular core. Or triggerable and / or fusible materials are used for the core / core structure 2. The braiding device 1 is used in the manufacture of a bicycle rim for producing a preform, wherein reinforcing fibers are braided around the core structure 2 at a certain angle. After the braiding has taken place, the core structure 2 is at least single-ply, preferably multi-ply, braided with the reinforcing fibers. The reinforcing fibers are formed here as carbon fibers, more preferably, however, alternatively or additionally aramid and / or glass fibers are used as reinforcing fibers.

The braiding device 1 has a running plate 4 having a through-hole 3. The through hole 3 is arranged centrally / centrally in the running plate 4. The running plate 4, how particularly well in combination the Fig. 1 and 2 to recognize, is formed substantially annular. In particular, the running plate 4 is formed in the region of the through hole 3 in a circular shape and consequently has a circular inner peripheral side 15. The running plate 4 is formed substantially like a disk. Also, the outer side 5 of the running plate 4, namely an outer peripheral side, is, as in Fig. 2 easy to recognize, essentially circular. In a further embodiment, this outer side 5 and / or the inner peripheral side 15 is polygonal or oval. In the running plate 4, a gap 6 extending from the outside 5 in the radial direction to the through hole 3 is introduced. Through this gap 6, the rigid running plate 4 is recessed / split in a peripheral region and therefore not completely formed circumferentially.

The braiding device 1 has a multiplicity of impellers 7, which are provided in the running plate 4 for moving a plurality of clusters, not shown here for clarity, along two wave paths 8, 9, hereinafter referred to as first wave path 8 and second wave path 9. How to stay in good Fig. 2 can be seen, the first wave path is formed sinusoidally extending substantially along the circumference. The second wave path 9 is formed sinusoidally extending along the circumference. Mathematically speaking, the two wave paths 8 and 9 extend with the same frequency and amplitude along the circumference of the running plate 4. The two wave paths 8 and 9 are further arranged with respect to their extension by 180 ° out of phase with each other, so along the circumference always a wave crest 16th the first wave path 8 with a wave trough 17 of the second wave path 9 and in turn an adjacent wave peak 16 of the second wave path 9 with a wave trough 17 of the first wave path 8 is superimposed. The wave paths 8 and 9 always intersect at their turning points, which are referred to below as the crossing point 18. Between two mutually adjacent to each other along the circumference crossing points 18 is an impeller 7 in an island region 19, within the surrounding wave paths 8 and 9 respectively arranged. Each impeller 7 is rotatably mounted on the running plate 4.

With each impeller 7, a drive gear 10 is rotatably connected. A first drive gear 10a is connected in a rotationally fixed manner to a first impeller 7a arranged next to the gap 6 in a first circumferential direction. For the rotationally fixed connection of the first drive gear 10a with the first impeller 7a is a first drive shaft 20a. A second drive gear 10b is rotatably connected to a, in a first circumferential direction opposite, the second circumferential direction adjacent to the gap arranged second impeller 7b. For the rotationally fixed connection of the second drive gear 10b with the second impeller 7b, in turn, serves a drive shaft, namely a second drive shaft 20b. The two drive shafts 20a and 20b extend parallel to each other. Also, the two drive shafts 20a and 20b extend substantially in the axial direction of the running plate 4, that is, substantially normal to a plane in which the running plate 4 extends.

According to the first embodiment, the two drive gears 10a and 10b mesh directly with each other in a common (first) toothing plane 11. The first toothing plane 11 is arranged offset in the axial direction relative to the plane of the running plate 4 in such a way that the core structure 2 is freely positioned / inserted in the operating state in an axial gap 12 formed between the first toothing plane 11 and the running plate 4. In the operating state, the core structure 12 is positioned and driven in such a way relative to the running plate 4 that the round core structure 2 is always in the through hole 3 with the portion to be braided. During the rotary drive of the core structure 2 relative to the running plate 4 or while displacing the running plate 4 along the core structure 2, the core structure 2 is always positioned with its section to be braided in the center / in the region of the center of the running plate 2.

As continues in Fig. 1 can be clearly seen, the distance between the running plate 4 and the first toothing plane 11 is given in particular by the length of the two drive shafts 20a and 20b. These drive shafts 20a and 20b are formed substantially equal in length, so that the two first and second drive gears 10a and 10b are at a same axial height, that is, at a same axial distance from the running plate 4. The drive gears 10 are front teeth / formed as a straight toothed spur gears. The two impellers 7a and 7b are thus coupled in a coupled manner by means of the two drive gears 10a and 10b.

With the first impeller 7a, in turn, a circumferentially adjacently disposed further, namely third impeller 7c is coupled for movement. Also, the third impeller 7c is rotatably connected by a third drive shaft 20c with a third drive gear 10c. The third drive gear 10c is engaged with the first drive gear 10a. Also, the third drive shaft 20c is configured substantially the same length as the first and the second drive shaft 20a and 20b, for which reason the toothing plane formed between the first and the third drive gearwheel 10a and 10c corresponds to the first gearwheel plane 11.

Along the circumference, on a peripheral side of the gap 6, which faces away from the first impeller 7a, the second impeller 7b in turn with a fourth impeller 7d in operative connection. For this purpose, the fourth impeller 7d is rotatably connected by means of a fourth drive shaft 20d with a fourth drive gear 10d. The fourth drive gear 10d meshes in turn in the first toothing plane 11 with the second drive gear 10b. The length of the fourth drive shaft 20d again corresponds to the length of the first and second drive shafts 20a and 20b.

The impellers 7 are all on a front side ( Fig. 2 ) of the running plate 4, namely mounted on a drive toothed wheels 10 facing away from the axial side. The impellers 7, which are formed substantially the same, are formed like a disk. The impeller 7 have all on its outer peripheral side drive means 13 to drive here for clarity, not shown on bobbin / yarn carrier. The drive means 13 is formed as a recess extending radially inwardly from a substantially circular outer peripheral side of the impeller 7, in the form of a groove. The width of the recess (ie, the extent of the recess along the circumference of the impeller 7) is matched to the outer circumference of a carrier rod of the bobbin / yarn carrier. The recess is designed such that the clapper is briefly absorbed during movement along the wave path 8 or 9 in this recess and up to the adjacent impeller 7 is transported (in the region of the intersection point 18), where he then turn into the next recess of adjacent impeller 7 is passed.

The first and the second impeller 7a and 7b are further formed such that they have in the region of this recess a holding mechanism 14 which is in the form of an in Fig. 5 formed magnet is formed. In a further embodiment, the holding mechanism 14 is formed as a click mechanism, as a clamping mechanism or as an alternative curved path in the running plate 4. This makes it possible, when opening the gap 6, that is at Inserting or implementing the core structure 2, the bobbin on a megnetisierbarem section so firmly to position so that they are kept spaced from the gap 6. The clappers are thus temporarily held in the recesses. The holding mechanism 14 is briefly activated for insertion or for carrying out the core structure 2.

Along the circumference, the two impellers 7a and 7b each have a flattened region, hereinafter referred to as flattening 21, on. A first flattening 21 a on the first impeller 7 a and a second flattening 21 b on the second impeller 7 b are designed substantially the same. The flats 21 a and 21 b are introduced in the radial direction from an outer peripheral side of the respective impeller 7 a, 7 b ago in the first and the second impeller 7 a, 7 b. Consequently, the respective impeller 7a, 7b has a smaller diameter in the region of the flattening 21a, 21b than at the regions adjacent to the circumference.

In a rest position, that is, in a position in which the core structure 2 is inserted into the running plate 4 for braiding, or in which the already braided core structure 2 is pulled out of the running plate 4, the two impellers 7a and 7b are rotated in such a way that the two flats 21 a and 21 b are opposite in the circumferential direction, ie facing each other. The flattening 21 a and 21 b are selected with respect to their depths that they do not protrude beyond the gap 6 in this rest position, but in turn form a radial gap which is at least as wide, preferably even wider than the gap 6 in the rotor plate 4 , Thus, the full gap width / width of the gap 6 is opened in this rest position and not obstructed in the radial direction by a portion of the impellers 7a or 7b. The gap width is chosen here between 20 mm and 40 mm. Alternatively, however, it is also possible to choose the gap width between 1 mm and 100 mm.

Further, on the two third and fourth drive shafts 20c and 20d, not only the one drive gear 10c or 10d but also another one Additional gear 22 rotatably arranged. This auxiliary gear 22 is mounted between the respective third or fourth drive gear 10 c or 10 d on the respective third or fourth drive shaft 20 c or 20 d to the drive plate 4 out. As a result, a first auxiliary gear 22a is non-rotatably arranged on a portion of the third drive shaft 20c projecting from the drive plate 4 in the direction of the third drive gear 10c at a portion close to the drive plate. The first additional gear 22a is in turn meshed with a further, namely a fifth drive gear 10e in engagement.

As a result, it is advantageously possible to shorten a further drive shaft 20 adjacent to the circumference for connecting the respective impeller 7 to the respective drive wheel / drive gearwheel 10. Consequently, an additional gear 22, namely a second additional gear 22d is rotatably disposed on the fourth drive shaft 20d. Also, this second additional gear 22b is rotatably disposed on the part of the running plate 4, namely on a region of the fourth drive shaft 20d protruding to the fourth drive gear 10b. The second auxiliary gear 22b is in turn engaged with a sixth drive gear 10f. All further adjoining impellers 7 and drive gears 10 thus likewise have a shortened drive shaft 20. The second toothing plane 23 thus formed, that is to say that toothing plane between the first additional gear 22a and the fifth drive gear 10e which corresponds to the toothing plane between the second additional gear 22b and the sixth drive gear 10f, is arranged between the plane of the running plate 4 and the first toothing plane 11 ,

In a further, second embodiment, as in Fig. 3 It can also be seen, in the gap 6, between the first and the second impeller 7a and 7b, a removable and reusable connecting element 24 is introduced / provided. The rest of the structure and the operation of this embodiment correspond to the first embodiment, which is why below only the differences will be discussed. The connecting element 24 is detachable and refastenable to the running plate 4 is arranged. Thus, the connecting element 24 present on the running plate 4 and in the operating state in the running plate 4, the gap 6 occlusive used.

In the connecting element 24 here the clarity not shown guideways are formed. The guideways serve to guide the clappers in the connecting element 24. The connecting element 24 is removed when the core structure 2 is inserted or withdrawn and inserted when the core structure 2 is braided in the operating state of the braiding device 1. A releasable attachment of the gap 6 bridging connection element 24 is possible with a non-positive and / or positive fastening method, preferably a screw connection. The connecting element 24 has substantially the same width as the gap 6, which is why it completely fills the gap 6 / bridged. In addition, the connecting element 24 also has an impeller 7 (also referred to as a connecting impeller) in order to convey the clappers along the guideways (not shown for the sake of clarity) in the connecting element 24 over the gap 6. Thus, a further impeller 7 between the first and the second impeller 7a, 7b from the gap 6 can be removed. Here then at least one clapper is held / fixed in a recess of the removable impeller 7 in the rest position. The connecting impeller of the connecting element 24 is rotatably connected to a connecting gear. The connecting gear is disposed in the operating state so as to mesh with the first and second driving gears 10a, 10b, and the connecting impeller is between the first impeller 7a and the second impeller 7b for relaying the clapper between the first impeller 7a and the second impeller 7b arranged.

In a further, third embodiment, as in Fig. 4 can be seen, a further plate in the form of a guide plate 25 is arranged in the axial direction between the running plate 4 and the sake of clarity, not shown first toothing plane 11, which leads the clapper additionally. The remaining structure and the operation of this embodiment correspond to the first embodiment.

In addition, it should be noted that it is also possible according to a further embodiment, the running plate 4 in several parts, approximately in two parts, to design. For example, the running plate 4 is then divided in a further peripheral region, which is at a distance from the gap 6. The two plate parts are then by means of a displacement or a pivoting (connection of the two plate parts with swivel joints / hinges) relative to each other movable and the running plate 4 additionally openable, so that the gap width 6 would be variably adjustable. This makes it possible to insert even larger core structures 2 into the interior of the running plate 4 / into the through hole 3.

According to a further embodiment, it is also possible with the running plate 4, namely on an axial side of the running plate 4 facing away from the drive gears 10 to fix an additional form ring, which then also along its circumference at a certain point, namely preferably in the peripheral region of the gap 6, split.

According to a further embodiment, at least one or both impellers 7a, 7b are formed in a divided manner, whereby a small part of the impeller 7a, 7b is removable in order to generate the gap and to release the gap 6.

The braiding device 1 is in this case substantially corresponding to that in the US 1,524,684 disclosed braiding machine designed and functioning, which document should therefore be considered as integrated herein.

When using the braiding device 1 for braiding the endless core structure 2, consequently, first the bobbins are positioned at a distance from the gap 6 in the vane wheels 7. In order subsequently to release the gap 6, the first and the second impeller 7a, 7b are to be positioned in such a way that a section of the core structure 2 can be freely inserted into the through hole 3 in the radial direction through the running plate 4. Thereafter, the endless core structure 2 to be braided is positioned in the running plate 4, and a braided fiber layer is applied to the core structure 2 by a relative movement (the core structure 2) to the running plate 4 and by moving the clappers along the wave paths 8 and 9 by means of the impellers 7 ,

In other words, thus a braiding device 1 is executed, which has a gap 6 between the impellers 7. An open Flechtrumpf (running plate 4) is provided with a gap 6 between the impellers 7 (possibly even two or more columns). The gap 6 is so large (about 20mm to 40mm) that a Felgenpreform (core structure 2) fits through. Preferably, the gap 6 is also smaller, including the Felgenpreform 2 is folded and later printed using a Blasschlauches again. The gap 6 is more preferably between 1 mm and 100 mm in size. (If the gap is not wide enough to remove the braiding preform from the machine, the machine can also be pushed.) Both impellers 7a, 7b have in a range a flattened area 21 a, 21 b. The impeller 7a, 7b can also be split (small part decrease) to create the gap or the entire impeller 7a, 7b is removed from the machine (possibly with two bobbins on the impeller 7a, 7b). Usually, two clappers are parked on the side before the core structure is pushed in or out. While the clapper is running over the gap, it can be guided by the impeller 7a, 7b, this can be done by magnet, clamping mechanism, click mechanism or an alternative curved track which works independently of the wave paths 8, 9. Also, the gap 6 can pass through the impeller axis. The open Flechtrumpf 4 then has a gap 6 on the Flügelradachse (the entire impeller 7 is out together with the gear 10 out to the gap 6 to open completely). For this, the clappers are held back in the impeller cutout (magnet, ...). As an additional element, a second plate 25, which sits slightly lower than the running plate 4, support the leadership of the clapper. In addition, a braided ring / form ring or even more Flechtringe / form rings is providable.
