Description

Method for preparing a spinning bobbin and preparation device

Technical Field

The invention relates to a method for preparing a spinning bobbin for a subsequent rewinding process on a working position of a winding machine, wherein the winding machine has an automatic bobbin conveying system, wherein in a preparation device, a yarn end is separated from the spinning bobbin, is grabbed and is positioned in a preparation position, wherein the spinning bobbin is conveyed on a conveying medium in the bobbin conveying system, and the spinning bobbin or the conveying medium comprises a storage medium with information relating to the respective spinning bobbin. The invention further relates to a preparation device for preparing a textile bobbin and a winding machine comprising such a preparation device.

Background

With regard to ring spinning machines, it has long been known and is described in a large number of patent applications that a spinning bobbin containing a relatively small amount of yarn material produced on a textile machine must first be rewound into a crosswound bobbin before it can be further processed on a subsequent textile machine, for example a textile machine, in the production process. Rewinding such relatively small yarn bobbins into relatively large wound cross-wound bobbins is generally carried out at the winder station.

In the case of a bobbin being supplied by a ring spinning machine, so-called preparation is usually required, since the yarn end of the bobbin rests on the ring spinning machine, and therefore cannot be taken up at the winder station and accordingly cannot be transferred to the yarn supply part of the station without special measures. Usually, the spinning tube has a so-called back stitch, which is determined by the mode of operation of the ring spinning machine. That is, in a ring spinning machine, it is common at the end of a spinning tube sub-journey that at the end of a so-called batch spinning, the ring plate is displaced from its high position into its low position in order to apply a so-called lower coil to the spindle's spindle disc, which is necessary to be able to automatically start the ring spinning machine spinning again after a spinning tube doff. During the downward movement of the ring rail, several yarn loops are applied to the surface of the spinning bobbin which is still rotating, which is generally referred to as the back loop.

Such a relatively fixed rear thread loop on the surface of the spinning tube is also advantageous during the transport of the spinning tube from the ring spinning machine to the downstream winding machine, since the risk of forming a trailing yarn is prevented, for example. However, in the winding-up station, such a permanent attachment of the back stitch to the surface of the bobbin is disadvantageous, since it is generally not possible to detach the back stitch and thus the end of the bobbin thread in this region.

In an automatic bobbin tube transport system, a spinning bobbin runs on a transport medium. In such bobbin transport systems, the winding state of the spinning bobbins or data relating to the individual spinning bobbins are usually stored on a storage medium at/in the transport medium or the spinning bobbins themselves. The reading device can read the information arranged thereon and avoid in the transport path ensures that the spinning bobbins are further transported to the respective transport section.

For this reason, it is common in the textile industry that the spinning tube, on its way from the ring spinning machine to the winding-machine station, first passes through a preparation device of an automatic bobbin transport system, in which the yarn ends are respectively detached from the surface of the spinning tube and are positioned for the subsequent rewinding process in a preparation position on the spinning tube, so that they are easy to handle for the yarn handling and guiding components of the winding-machine station.

Various embodiments of a preparation device for preparing a textile bobbin are therefore known in the textile industry and are sometimes described in a very clear manner in a large number of documents.

According to DE3602002a1, the device comprises a cutting mechanism for separating and cutting off the thread strand passing by the cutting mechanism, a thread end taking-up mechanism arranged along the path near the cutting mechanism for taking the thread end off the bobbin thread end and a thread end introducing mechanism arranged near the thread end taking-up mechanism for introducing the taken-up thread from the bobbin head into the central opening of the bobbin. The bobbin, the yarn end of which is successfully gripped and the yarn end of which is positioned with a fixed length into the central opening of the spinning bobbin, is guided into a transport path and fed to a winding machine.

DE102006050219a1 describes a device comprising a yarn opening station for opening the yarn end and a yarn end acquisition station for acquiring and depositing the yarn end in a ready position. The preparation takes place in the form of an upper coil, referred to here as a coil tip, i.e. a predetermined number of coils are wound onto the bobbin tip in the region of the bobbin tip.

When the end of the thread is deposited in the form of a loop, in particular in the case of a relatively smooth thread, the formation of a trailing thread in the path from the preparation device to the winding position is not excluded, the thread length is often insufficient to deposit in the bobbin tube, in particular in the case of a relatively small spinning bobbin. Thus, DE4424462a1 discloses a device in which, when the spinning bobbin continues to rotate after the formation of the pointed stitch, the remaining yarn end is automatically guided directly through the center of the bobbin opening for subsequent secure insertion into the bobbin.

Common to all known preparation devices is that a type of preparation is always carried out in each case with the corresponding positioning of the thread or thread end in the preparation position. In a preparation device, the spinning bobbin yarn is either loosely deposited in the hollow bobbin or is somewhat detachably prepared in the form of an upper thread loop in the region of the bobbin tip or positioned as an upper thread loop and subsequently in the bobbin tip in each spinning bobbin to be prepared.

Different winding states (for which different preparation positions of the yarn on the spinning bobbin are advantageous) are ignored. The winding state can be, for example, the amount of yarn stored on the spinning bobbin. However, or when the bobbin is not completely unwound, for example because the thread end can no longer be caught in the winding position after a thread break or the clearer detects a number of thread defects exceeding a limit value. The yarn bobbin is delivered from the working position, and the information is recorded on the storage medium. The other winding state can also be a yarn bobbin in which, despite the preparation, the yarn end cannot be caught in the station by the yarn treatment and guide element of the station and which still has the full initial yarn quantity.

Also, known preparation devices may be less flexible to react to processing different batches simultaneously. The upper thread loop is advantageously prepared for a yarn of a defined quality, but is more suitable for other yarns to be deposited in the bobbin tip. Another point is that in the known preparation device the number of upper coils to be formed cannot be changed as required and can be adjusted for the respective winding state.

Disclosure of Invention

A first aspect of the invention therefore relates to a method for preparing a spinning bobbin for a subsequent rewinding process at a station of a winding machine, the winding machine having an automatic bobbin tube transport system, wherein in the preparation device a yarn end is detached from the spinning bobbin, gripped and positioned in a preparation position, wherein the spinning bobbin is transported on a transport medium within the bobbin tube transport system, and the spinning bobbin or the transport medium contains a storage medium with information relating to the respective spinning bobbin.

The method is characterized in that in a first step, different winding states of the textile bobbins are defined and respectively assigned a preparation type comprising a preparation position for the yarn end, in a second step, the different winding states are stored in the control unit together with the associated preparation type, in a third step, information about the winding state of the respective textile bobbin is read in the preparation device, in a fourth step, the read information about the winding state is compared with the stored winding state, and in a fifth step, the textile bobbin is prepared according to the preparation type assigned to the winding state thereof, either by forming a top thread on the bobbin tip and/or by placing the yarn into the bobbin tip.

In the bobbin transport system, the spinning bobbin runs on a transport medium, which is also commonly referred to as a transport plate, and after it has passed through the preparation device and the yarn ends have been placed in the preparation position as intended, is guided to a transport section leading to a winding machine station. Information about the respective spinning bobbin, including the winding state and other data, is stored on the storage medium. The reading device can read the information arranged thereon and the avoidance on the transport path ensures that the spinning cylinder continues to the respective transport section.

The information stored on the storage medium about the respective spinning bobbin contains not only, for example, a spinning position identifier or a technical parameter, such as the titer or twist number of the ring spun yarn, but also data about the processing and the events occurring at this time. That is to say, when, for example, a spinning bobbin is not ready to be rewound in a defined manner at a winding station, this is written down on the storage medium, and the spinning bobbin is subsequently discharged from the station and possibly fed back to the preparation device. The inventors have recognized that different types of preparation with regard to the yarn end preparation position on or at the spinning bobbin are advantageous for different winding states or states of the spinning bobbin for the subsequent winding process. The different winding states of the spinning bobbin correspond to different preparation types, in particular different preparation positions for the yarn end on the spinning bobbin, and are stored in the control unit.

If the spinning bobbin enters the preparation device, the winding state is read from the storage medium and compared with the winding state stored in the control device. As soon as a match of the winding state of the current yarn bobbin with that stored in the control device is detected, the type of preparation associated with the winding state is carried out and the yarn end is slightly releasably wound onto or inserted into the bobbin tip as an upper thread loop or already rests on the bobbin tip as an upper thread loop and is then inserted into the bobbin tip.

In this way, the preparation of the spinning bobbin can be flexibly performed according to the winding state as required. Each individual spinning bobbin that is to be prepared is individually prepared for its respective winding state, and is optimally prepared for the subsequent rewinding process. The preparation type is adapted to the current state of the spinning bobbin or to the current winding state thereof, whether the spinning bobbin is fed directly from the ring spinning machine or from the winding machine station into the preparation device again. It is common in the prior art to perform one of three possible types of preparation in connection with the dropping of the yarn onto the spinning bobbin. According to the invention, the winding state of each individual spinning bobbin entering the preparation is queried and the optimal yarn setting is carried out.

By the practice according to the invention, other advantages are achieved, such as the beat rate targeted for the preparation or the presence of waste yarn in the winder station. In view of the fact that it takes more time to drop the upper coil than to drop the yarn in the bobbin tip, the upper coil always results in a loss of preparation takt efficiency. Thus, if the yarn is deposited as an upper thread in each of the yarn bobbins, fewer yarn bobbins can be prepared in the same period than if the yarn was deposited into the bobbin tip in all the yarn bobbins. In addition, the upper thread loop always results in more waste thread at the working station, since the thread end is released again and the thread layer wound as an upper thread loop is sucked and cut off, whereupon the thread can be joined and rewound.

Since the preparation type is carried out as required in relation to the yarn preparation position on the spinning bobbin and the upper thread winding is only completed when this is advantageous for the subsequent winding process, either alone or in combination with the placement of the yarn in the bobbin tip, the preparation time is overall faster than the preparation of forming an upper thread winding in each spinning bobbin at the time, and the yarn waste is reduced. Nevertheless, the advantages of the upper coil can be utilized if desired.

In an advantageous embodiment, the number of upper coils is part of the preparation type when forming the upper coils.

The desired number of upper turns is in principle settable. It may occur that too little yarn is stored to place a predetermined number of upper stitches. In this case, it may occur that at the end of the winding of the upper thread loop, no thread is present anymore, so that the thread is no longer held in the preparation device by the thread brake. In the worst case, the entire upper thread loop can thus already be sucked in during preparation by the suction device, so that finally no thread ends are left on the spinning bobbin, which are ready for use. In the case of such spinning bobbins, the yarn end is generally not found in the station by the yarn treatment and guide elements of the station, and the spinning bobbin is unwound off. If a spinning bobbin of this type is re-entered into the preparation device and this information is read by the reading device, a new upper thread loop can be formed in a reduced number and the spinning bobbin is then ready in order at the station.

The characteristic representing the winding state is preferably the amount of yarn located on the spinning bobbin.

Depending on the amount of yarn present on the spinning tube, different types of preparation may be advantageous. If only a relatively small amount of yarn is present on the spinning bobbin, it is advantageous, for example, if the yarn is located as an upper thread loop on the bobbin tip, rather than being inserted into the bobbin tip. Since less yarn is generally arranged on the bobbin of the spinning bobbin in the lower region, the distance from the bobbin tip to the yarn package, with which the yarn is loosely placed on the bobbin, is relatively large. In this way, it can be relatively easy for the thread end to be pulled out of the bobbin tip in a uncontrolled manner during further transport and to become entangled as a trailing thread in the bobbin transport system. A full-package bobbin with more yarn than this can be prepared for subsequent optimal yarn gripping in the station by placing the yarn in the bobbin tip. The distance between the bobbin tip and the yarn winding is relatively small, so that there is a small amount of free surface of the yarn which is loose against the bobbin tube.

It is certainly possible here to produce a bobbin with a smaller amount of yarn than usual in a spinning machine, or to let out a bobbin that has not been completely unwound from a workstation of a winding machine and to feed it in order to be ready.

Advantageously, the characteristic that represents the winding condition is the number of bobbins that are fed again in the winder station that cannot catch the yarn.

Such information is also stored on the storage medium if the prepared yarn cannot be grasped by the yarn processing and guiding components of the stations and therefore cannot be subjected to the rewinding process. If the textile bobbin is prepared in one type of preparation and if it is not useful to try to catch the yarn at the workstation a predetermined number of times, the subsequent preparation can be carried out in an alternative type of preparation. For example, if a yarn bobbin is prepared for placing the yarn into the bobbin tip and if it is not useful to try to catch the yarn three times at a station, a subsequent preparation by forming the upper thread loop can be carried out. Thus, the preparation type can be automatically adjusted according to the requirement. The number of times that attempts to seize the thread are made before an alternative type of preparation is made is individually adjustable.

In particular, the characteristic feature representing the winding state is the incompletely unwound bobbin issuing from the winding machine station.

If the spinning bobbin is not completely unwound because, for example, the thread end can no longer be gripped in the winding position after a thread break, this information is recorded on the storage medium and the spinning bobbin is discharged from the workstation. If such a spinning bobbin again enters the preparation device, this information is read and the spinning bobbin is prepared according to the preparation type assigned to its winding state.

In one advantageous embodiment, the characteristic which represents the winding state is the batch.

For different batches, different preparation types, in particular different yarn placements on the spinning bobbin, may be advantageous for the yarn to be gripped by the yarn handling and guiding means of the winder station. For example, a smooth thread can often be prepared better by inserting the thread into the bobbin tip, since, in the preparation with a winding, it is possible for the thread to leave the spinning bobbin during the transport from the preparation device to the working position and to become entangled in the transport path. While in particular a rough yarn generally has a good adhesion when it is wound as an upper loop on the bobbin tip, with only a slight risk of detachment during transport. However, other parameters or technical characteristics, such as, for example, the twist and the titer of the finished yarn, may also influence the optimal type of preparation.

In a further alternative embodiment, the type of preparation of the spinning bobbins is stored on a respective storage medium.

If the preparation device comprises not only a reading device for reading information about the winding state of the respective spinning bobbin, but also a writing device, the type of preparation carried out in each case and in particular in which preparation position the yarn end or how many windings are to be prepared are also stored on a storage medium belonging to the spinning bobbin. This is advantageous in particular with regard to the possibility of gapless tracking during the entire production process.

A second aspect of the invention therefore relates to a preparation device for preparing a spinning bobbin for a subsequent rewinding process at a station of a winding machine, the winding machine having an automatic bobbin tube transport system, wherein in the preparation device a yarn end is detached from the spinning bobbin, gripped and positioned in a preparation position, wherein the spinning bobbin is transported on a transport medium within the bobbin tube transport system, and the spinning bobbin or the transport medium comprises a storage medium with information relating to the respective spinning bobbin.

The proposed preparation device is characterized in that the control device is designed to store different winding states of the textile bobbins and to be able to assign to the respective winding states a respective preparation type of the textile bobbins, including a preparation position for the yarn end, and at least one reading device is provided for reading and forwarding information stored on the storage medium about the winding state of the textile bobbin provided thereon to the control device, and in that the winding state information is compared with the stored winding state in the control device, and in that the control device activates the preparation type assigned to the respective winding state in the preparation device.

In this way, the preparation device reacts to different winding states of the spinning bobbin in different preparation types according to requirements. That is, depending on the winding state or the state of the yarn package, a preparation type can be prepared in accordance therewith. The type of preparation can comprise a preparation position of the yarn on the spinning bobbin and/or the number of upper windings wound on the bobbin tip for the yarn treatment and guide element of the winding machine station. The winding state in the context of the invention is, for example, the yarn quantity of the yarn on the spinning tube or the associated batch. The winding position can also be a position of the spinning bobbin, such as, for example, a position of the spinning bobbin in which the yarn is not successfully gripped and is not unwound, i.e. is present in the entire initial yarn quantity, or a yarn end cannot be gripped again at a station after a yarn break and the spinning bobbin is therefore not completely unwound. The information is stored on a storage medium, and the respective yarn bobbin is discharged from the working position and is possibly sent to the preparation device again.

The control device, which stores the winding state and the type of preparation and compares the information read from the storage medium about the winding state of the respective textile bobbin with the information stored therein, may be, for example, a station computer or a central control unit within the scope of the invention. A separate computing unit in the preparation device is likewise conceivable. It is only essential to the invention that a correspondingly designed control unit be used for this purpose.

Although the preparation device in the prior art performs the preparation type for all the spinning bobbins, the preparation device of the present invention can be changed between three preparation types. The preparation device according to the invention is more efficient and has a higher takt efficiency than a preparation device which always forms an upper thread loop, since placing an upper thread loop takes in principle more time than placing the yarn in the bobbin tip. Nevertheless, an upper coil can be formed if necessary and meaningful. In all other yarn bobbins, however, the yarn is placed in the bobbin tip.

Another advantage is that the waste yarn is reduced compared to a preparation device that always forms the upper stitch. The upper thread loop is gripped, unwound, sucked and cut in the station by means of the thread treatment and guide elements, the thread end is then connected to the thread end present on the station and the winding process is started. When only the winding state thereof is such that the bobbin above the stitch, which is necessary to wind the yarn as the upper stitch, is prepared, the occurrence of the waste yarn can be reduced as a whole. But nevertheless the upper coil can in principle be formed if desired.

Advantageously, in addition to the reading device, a writing device is provided which stores the preparation type on the storage medium after the preparation of the spinning bobbin has been carried out and the number of upper windings if required.

Thus, the type of preparation performed accordingly may be stored on the storage medium and subsequently understood. This is particularly advantageous in terms of gapless product tracking in the industrial 4.0 sense.

A third aspect of the invention therefore relates to a winding machine having a preparation device for preparing a spinning bobbin for a subsequent rewinding operation at a station of the winding machine, the winding machine having an automatic bobbin tube transport system, wherein a yarn end is detached from the spinning bobbin, received and positioned in a preparation position in the preparation device, wherein the spinning bobbin is transported on a transport medium in the bobbin tube transport system, and wherein the spinning bobbin or the transport medium comprises a storage medium with information about the respective spinning bobbin.

The winder is characterized in that the preparation device is designed according to one of the embodiments described above.

The advantages and effects described in connection with this can thus be achieved.

Other features and advantages of the invention will be apparent from the following description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the important details of the invention. Some of the individual features may be implemented in the preferred embodiments of the invention either individually per se or in any combination of a plurality.

Detailed Description

Fig. 1 schematically shows an embodiment for the combination between a ring spinning machine 1 and a winding machine 2 in a top view.

The transport systems of the two textile machines are joined by a connecting system 3, as is known per se and therefore only schematically indicated by the arrows. The transport system installed in the region of the ring spinning machine 1 is not described in detail since it is known on the one hand and is not the subject matter of the present application on the other hand.

The bobbin transport system 5 arranged in the region of the winding machine 2 is provided, as is conventional per se, with various transport sections, such as, for example, a spinning bobbin supply section 6, a bobbin return section 7, a reversibly drivable storage section 8 and a transverse transport section 9 to the working position 4, wherein the transverse transport section 9 can be equipped in the region of its waiting position with a sensor device 16, which is connected via a signal line 17 to a control device 18 of the winding machine 2.

Furthermore, a so-called preparation section 10 is connected to the spinning bobbin supply section 6, which is connected at the end to the reservoir section 8 or in turn to the spinning bobbin supply section 6 via a branching section 11. In the area of the preparation section 10, a preparation device 12 for a textile bobbin is arranged.

In the preparation device 12, the bobbin produced on the ring spinning machine 1 is prepared in such a way that it can be subsequently processed, i.e. rewound, in the station 4 of the winding machine 2. The preparation device 12 may have, for example, the structure of DE4424462a 1. It is only essential to the invention that the preparation device 12 can prepare the yarn not only as an upper thread on the bobbin in the preparation position, but also as a yarn entering the bobbin tip in the preparation position, or in a combination of the two preparation types, so that the preparation device 12 can finally carry out the three preparation types.

The preparation device 12 is connected to the control device 18 of the winder 1 by a signal control line 15. The preparation device 12 comprises a reading device 13, by means of which data relating to the respective spinning bobbin and in particular data relating to the winding state, which are stored on a storage medium, can be read. The data are forwarded to the control device 18 and a comparison takes place between the currently read winding state and the winding state stored in the control device 18.

If a spinning bobbin which has not yet been completely unwound enters the preparation device 12, for example because the thread end can no longer be gripped at the station 4 after a thread break and the amount of remaining thread on the spinning bobbin is below a predetermined limit value, the type of preparation assigned to this winding state is carried out and the thread is deposited on the bobbin tip with the upper thread loop. Subsequently, the bobbin is again fed to a station 4 of the winding machine 2 in order to be completely unwound there.

The preparation device 12 can also optionally comprise a writing device 14, by means of which the type of preparation performed and in particular in which preparation position the yarn is laid on the bobbin and is thus ready can be stored.
