Description

The invention relates to a chuck for winding a plurality of threads, which is rotatably mounted on a winding spindle carrier of a winding device according to the preamble of claim 1 and an associated winding device with the chuck.

A winding device of this type is made, for example, of DE10 2022 116 443 B3 which describes and claims an external drive in the form of a traction drive for the chuck.

In winding machines known from the state of the art, several threads are wound parallel to one another at the same time into spools.

For this purpose, the winding device has a cantilevered chuck, on the circumference of which several sleeves are locked to hold threads wound up by the winding device. The chuck is mounted so that it can rotate on the circumference of an axis. The axis is firmly coupled to a winding spindle carrier, which usually provides a second axis for holding a further second chuck. The axes on the winding spindle carrier are arranged offset by 180° from one another. The winding spindle carrier is mounted so that it can rotate in a machine support frame of the winding device, so that an essentially continuous winding or spooling of the threads is possible alternately on the chucks.

One chuck is moved to a winding position at a time, while the other chuck is in a doffing position so that it can be fed with new cores when the cores have been wound into a complete coil package.

The chuck can be driven by a traction drive, in particular a toothed belt drive, which is guided over a toothed ring on the circumference of the chuck and is driven by a drive.

In other winding devices, the chuck is driven by a shaft gear, whereby the shaft gear extends in the longitudinal direction of the chuck so that the shaft can rotate the chuck accordingly.

However, with very long chucks, the problem can arise that as the weight of the coil packages increases during winding, the chuck becomes deformed due to the bending stress.

This can be particularly disadvantageous with shaft-driven chucks, since the shaft gear and the associated shaft are not deformed to the same extent as the coil casing of the chuck.

Such loads can lead to high wear of the respective drive, especially in the case of chucks whose longitudinal direction is extended to accommodate additional spool packages.

It is therefore an object of the invention to further develop a chuck in such a way that it can also reliably withstand bending loads if the chuck is designed to project over a very long distance.

This object is achieved according to the invention with a chuck having the features of claim 1.

Advantageous developments of the invention are defined in the appended claims.

Furthermore, it is an object of the invention to provide a winding device which can be provided with chucks which are designed to project over a very long distance and can thus be operated safely.

This object is achieved according to the invention with a winding device having the features of claim 11.

Advantageous further developments of the winding devices are described in the features and combinations of features of the appended claims.

According to one aspect of the invention, a chuck for winding a plurality of threads is provided, which is rotatably mounted on a winding spindle carrier of a winding device, wherein the chuck has a bobbin casing projecting from the spindle carrier, which has on its circumference a sleeve clamping device for releasably fixing a plurality of sleeves, to which the plurality of threads can each be fixed, and has a drive which rotatably drives the bobbin casing for winding the threads. The bobbin casing has a first bobbin casing sleeve and a second bobbin casing sleeve, which are coupled to one another at opposite end sections in the longitudinal direction of the bobbin casing and are rotatably mounted on a support mandrel of the chuck.

With the chuck according to the invention it is possible in particular to form particularly long chucks which are only attached to a spool on one side spindle carriers are rotatably fixed and have a free cantilevered end.

A large number of sleeves can be fixed to the chuck using the clamping device. The clamping device is designed to be pneumatically releasable, for example, so that pre-tensioned clamping blocks are pre-tensioned against the sleeves to be fixed.

By pneumatically releasing the clamping mechanism, the sleeves or the threads wound on the sleeves can be removed from the chuck.

Since the wound sleeves lead to a greater load on the chuck, the chuck is provided with a coil jacket consisting of two coil jacket sleeves.

The two spool sleeves are rotatably mounted to one another via a load-bearing mandrel.

This allows the chuck to be lowered further as the load increases. According to the state of the art, the drive of the spool sleeve is provided inside the chuck up to the end of the chuck, which can also include the cantilevered end section.

Therefore, excessive loading of the chuck could have a negative effect on the drive shaft. The solution is a spool sleeve that has several spool sleeves that are rotatably mounted on a support mandrel.

The support mandrel is the load carrier of the chuck and is rotatably fixed to a winding spindle carrier. The winding spindle carrier can be, for example, a turret spindle that rotatably positions at least two winding spindle carriers on a winding device.

This allows you to alternate between winding or doffing the tubes fixed to the chuck with a synthetic thread. Doffing here means removing the tubes from the chuck.

According to one embodiment of the chuck, the first winding sleeve and the second winding sleeve are rotatably mounted on the support mandrel at two spaced-apart first and second locations.

A bearing point is understood to be a bearing position of the winding sleeve on the support mandrel, which allows the winding sleeve to rotate on the support mandrel.

The rotation of the bobbin sleeve can advantageously be carried out by a separate drive, which either acts circumferentially on the bobbin sleeve or acts on the bobbin sleeve via a shaft within the support mandrel, so that a rotation of the bobbin sleeves can be caused.

The bearing points can, for example, have ball and/or roller bearings, which are advantageously mounted on the support mandrel in a damped manner, so that corresponding deflections due to the load are not transferred directly to the support mandrel, but are cushioned and/or mitigated accordingly by the damping.

The winding jacket of the chuck according to the invention has two separate winding jacket sleeves which are coupled to one another, wherein the first and second winding jacket sleeves are rotatably mounted on the support mandrel by means of two first and second bearing points spaced apart from one another.

This allows the load to be transferred from the spool sleeves to the support mandrel via the bearing points, so that a particularly long cantilevered chuck is possible.

According to a further embodiment of the chuck, the first winding sleeve has the first bearing point on the winding sleeve carrier, at which the first winding sleeve is rotatably mounted on the support mandrel and the support mandrel extends from the winding spindle carrier.

Here, the position of the first bearing point with respect to the support mandrel and the winding sleeve is defined more precisely.

As a position specification, the position of the support mandrel with regard to its attachment to the winding spindle carrier is defined more precisely.

Advantageously, the first bearing point is also provided at the point where the load is transferred on and in the spool spindle carrier of the chuck.

According to another embodiment of the chuck, the first spool sleeve has a second bearing point at the coupling point with the second spool sleeve, wherein the second bearing point is positioned in the center of gravity area of the chuck.

Since the chuck has a spool jacket made up of two spool jacket sleeves extending from one another, the second bearing point is the coupling point between the first and second spool jacket sleeves.

This allows a particularly advantageous load transfer of the chuck. The support mandrel does not have to extend through the entire length of the spool casing, but can be fixed at advantageous positions on the spool casing.

An advantageous position for the second bearing point is the center of gravity of the chuck. This center of gravity area is set so that it is located at the coupling point of the first and second spool sleeve.

The coupling point allows the first and second clamping sleeve to rotate together and synchronously and also allows load transfer at the second bearing point to the support mandrel.

According to a preferred embodiment of the chuck, the bobbin casing is coupled to the drive at one end portion positioned adjacent to the bobbin spindle carrier or coupled to the drive at the end portion positioned opposite to the bobbin spindle carrier.

The chuck drive can act at different positions on the spray jacket. On the one hand, the drive with the winding jacket can be positioned next to the spindle carrier, so that at this point the drive also acts directly on the winding jacket.

In another embodiment, however, the drive can also be coupled to the drive at a position which is arranged at a distance from the spindle carrier, namely at the opposite end of the winding casing.

The opposite end of the winding sleeve is in particular the cantilevered end.

In the embodiment, the driving force of the drive is introduced via a shaft which, for example, extends partially through the chuck to the coupled end portion of the second clamping sleeve, which adjoins the end portion of the first spool sleeve.

According to another embodiment of the chuck, the first winding sleeve is drivably coupled to the drive at one end portion and rotatably coupled to the second winding sleeve at the other end portion, which is opposite to the end portion coupled to the drive, which extends in the longitudinal direction of the chuck from the projecting end portion of the first winding sleeve, wherein the second winding sleeve is non-positively connected to the first winding sleeve.

At the second bearing point, the first winding sleeve is also rotatably coupled to the second winding sleeve, so that the torque generated by the drive can be transferred from the first winding sleeve to the second winding sleeve without any losses occurring.

Preferably, the first and the second bobbin casing sleeve are connected to one another in a force-fitting manner at the opposite end sections, so that the first and the second bobbin casing sleeve together form the bobbin casing.

According to another embodiment of the chuck, the first bearing point and/or the second bearing point have/have a bearing and a damping device which is arranged between the bearing and the support mandrel, so that the first winding sleeve and the second winding sleeve are mounted so as to be rotatable in a damped manner around the support mandrel.

For optimal and improved transmission of the load forces occurring to the support mandrel, the bearing points are preferably designed to be dampened. Suitable damping means can be provided for the damping.

In one embodiment, the damping means can be, for example, a rubber bearing.

According to a preferred embodiment of the chuck, the first bearing point and/or the second bearing point each have two bearings which are adjusted and preloaded against each other.

In the preferred embodiment, the bearing points via which the coil casing or the coil sleeve are rotatably mounted on the support mandrel are each formed with two bearings, the effect of the bearings being such that they are preloaded in their direction of action and adjusted relative to one another.

By adjusting and pre-tensioning, a corresponding X or O arrangement can be created, whereby the bearing point has corresponding properties.

According to a preferred embodiment of the chuck, the bearings of the first bearing point and/or the bearings of the second bearing point are adjusted in an X-arrangement or in an O-arrangement.

The adjustment of a bearing means a defined preloading of the two bearings, usually two mirror-image angular contact ball bearings or tapered roller bearings, against each other. The name comes from the position of the pressure line through which Rolling bearings with a pressure center between the bearing points are referred to as X-arrangements, and outside the bearing points as O-arrangements. In O-arrangements, the bearing can absorb a larger tilting moment than in X-arrangements, since the distance between the pressure centers is greater in O-arrangements.

At the second bearing point, the coupling point between the first clamping sleeve and the second clamping sleeve, an O-arrangement is selected, whereby at the bearing point, the first winding spindle sleeve on the spindle carrier, an X-arrangement is provided for the respective bearings.

According to a further embodiment of the chuck, the damping device has at least one groove-shaped slot receptacle in the support mandrel and an elastic damping means, in particular a rubber damping.

For better damping and introduction of the vibrations caused by the rotation of the winding casing, the bearings are also elastically damped at suitable positions. The damping can be provided in corresponding groove receptacles. According to a preferred embodiment, this groove receptacle is designed in the shape of a groove, which extends circumferentially around the support mandrel and is formed therein.

According to a further aspect, a winding device for winding a plurality of threads by means of a chuck according to at least one of the preceding embodiments is provided, wherein the drive of the chuck acts on the first bearing point and/or the second bearing point.

The effective location of the drive at the first or second bearing point has various advantages.

The advantage of having the drive act at the first bearing point is that no shaft is required to drive the chuck, which extends through the entire chuck and can be obstructed by the spool sleeve if the deflection of the spool sleeve is too great.

When the drive acts on the second bearing point, a shortened shaft can be used which extends only partially through the chuck at least to the second bearing point.

A shortened shaft can compensate for larger deflections of the surrounding spool sleeve without restrictions than a shaft that extends through the entire chuck.

According to a further embodiment of the winding device, the drive of the chuck has a traction mechanism and/or a shaft gear. The drive is preferably a traction mechanism if the drive acts on the first bearing point. If the drive acts on the second bearing point, the drive is preferably a shaft gear.

According to a further embodiment of the winding device, the traction mechanism has a tensioning spool for tensioning a traction mechanism and a toothed ring which is in engagement with the traction mechanism, wherein the traction mechanism in particular has an arrow-shaped toothed belt.

By means of the traction mechanism, it is advantageously possible to provide a shaftless drive of the support mandrel on the spool carrier. This advantageously makes it possible to provide a drive that functions independently of the bending load on the chuck.

The traction means is preferably a toothed belt with an arrow-shaped toothing; the arrow-shaped toothing offers advantages with regard to the storage and positioning of the toothed belt in the toothed ring, which has a corresponding toothing, so that the toothed belt is not driven out of the toothed ring even when the chuck is loaded.

According to a further embodiment of the winding device, the gear ring is positioned at the first bearing point of the first winding sleeve of the winding sleeve, so that the drive of the traction mechanism can drive the gear ring together with the winding sleeve. The gear ring is in engagement with the winding sleeve, so that it can rotate the winding sleeve by means of the drive, so that the threads can also be wound up and spooled up by means of the sleeves and the winding sleeve.

According to a further embodiment of the winding device, a shaft of the shaft gear of the drive is coupled to the winding casing at the second bearing point so that the shaft can rotate the winding casing. Instead of the toothed gear, a shaft gear can also be used. The shaft gear has a shaft that extends at least partially through the winding casing to the second bearing point, where the shaft is in engagement with the winding casing and is coupled so that the torque of the drive can be transmitted to the winding casing.

The chuck according to the invention and the winding device with the chuck according to the invention are described below with reference to some Examples are explained in more detail with reference to the attached figures.
