Description

The present invention relates to a method on a spinning machine with a large number of spinning positions at which different yarn lots are spun, with a tube being transported by a transport device from one of a number of tube magazines to the spinning station, where a yarn is spun from a sliver deposited in a can and then wound up onto a tube, and a spinning machine with a large number of spinning positions at which different yarn lots are spun, with a number of tube magazines and with a transport device to move a tube from one of a number of tube magazines s to be transported to the spinning station and with a can and a sliver deposited therein in order to spin a yarn from it at the spinning station and then wind it up on a sleeve.

From the EP 0 916 614 A2 a central magazine for a tube supply device of a textile machine producing cross-wound bobbins is known, which has a storage device for receiving a large number of tubes and a tube transfer device for transferring the tubes to a machine-long transport device. Several sleeve magazines are arranged in the storage device as storage columns, which are characterized by different colors. They are therefore also suitable for textile machines that work in multi-batch operation. The risk of the operator loading the storage columns of the storage unit with the wrong empty tubes by mistake is additionally minimized by the fact that a storage device is arranged above each storage column, on which a sample of the tube required in the relevant storage column is stored.

The disadvantage here is that the storage columns have to be marked twice and it is still not clear to the operator to which lot and which spinning position the tubes belong. Incorrect assignments of the sleeves to individual batches can therefore still occur and lead to large losses due to unacceptable qualities in the spinning process.

The object of the present invention is to eliminate the disadvantages known from the prior art, in particular to make the machine easier to operate and to improve the quality of the yarn lots produced.

The object is achieved by a method and a spinning machine with the features of the independent patent claims.

A method is proposed on a spinning machine with a large number of spinning positions at which different yarn lots are spun, with a tube being transported from one of several tube magazines to the spinning position using a transport device, where a yarn is spun from a sliver deposited in a can and then wound onto a tube. According to the invention, the tube magazines and at least one or more of the following elements: tubes in the magazine, display device at the spinning position, monitor at a machine control, can at the spinning position, service device are provided with a similar marking related to the yarn lot.

If each of the tube magazines is provided with a corresponding marking and, in addition, another typical component of the spinning machine is also provided with the same marking, a quick automatic or visual check of the spinning machine with regard to the correct assignment of the tubes to this additional component can be carried out very easily and quickly. Unless it is found that the marks deviate from each other, this is an indication that, for example, the wrong tubes were delivered to the spinning station or the wrong can is present and the spinning process must be interrupted immediately.

The additional component can be, for example, the sleeve in the magazine. The marking on this case must be identical to the marking on the case magazine. This makes it much easier for the operator to fill the tube magazine. He can use the same markings as a guide and fill the case magazines accordingly. By displaying the marking on a display device at the spinning station, it can be checked whether the correct tube is at the spinning station, if the tube also has this marking or if it is the tube that comes from a tube magazine with the same marking.

On the other hand, if the marking on the can and the display at the spinning station are identical, it can be checked whether the right can with the right fiber material is at the spinning station.

If the marking is on a monitor of the machine control, it is also possible here for a specific batch of yarn to be assigned to the tube magazine. As a result, the input of certain parameters, which are necessary for the generation of the yarn lot, can be carried out very easily and without confusing it with another yarn lot.

If the service device is marked accordingly, it can also be checked very quickly and easily whether the service device has the settings required for the yarn lot and, accordingly, correct service work, such as cleaning the spinning position or changing the tube that has already been wound into a bobbin or replacing this full one sleeve with a new, empty sleeve. In the case of a spinning machine on which different yarn lots are spun at the same time and the service device accordingly requires different settings, it is possible here to reliably check whether the setting at the spinning position just processed is correct.

All of these checking options, which are carried out either by sensors or by the operator, ensure that the yarn lots are not mixed up and can therefore be produced by type.

There are advantages if the marking is changed with a change in the yarn lot. The marking preferably corresponds to a specific batch of yarn. If the yarn lot is changed at the spinning position or at the tube magazine, a change in the marking also indicates this change and helps to avoid mix-ups.

There are also advantages if the marking for the yarn lot is specified on the machine control. The specification of the marking can be made centrally on the machine control. It can also be determined at which spinning position and which tube magazine is provided for the corresponding yarn lot.

It is advantageous if the marking on the tube magazine, on the service facility and/or on the spinning station is selected. The setting of the correct marking can be carried out easily and error-free if this takes place directly at the tube magazine, at the service facility and/or at the spinning station, for example by actuating a button or switch.

It is particularly advantageous if the spinning positions are assigned to a yarn lot at the machine control and/or directly at the spinning position. In particular, the assignment of the spinning position of a yarn lot on the machine control is advantageous because here there is a particularly good overview of the already assigned spinning positions and the spinning positions still available on the spinning machine and accordingly an optimal distribution of the yarn lot to specific spinning positions can take place.

There are also advantages if the tube magazines are assigned to a yarn lot on the machine control and/or directly on the tube magazine. This assignment of the tube magazine to a specific yarn lot is preferably carried out on the machine control or directly on the tube magazine. In particular, there is an overview of the tube magazines that are available and not yet occupied by other yarn lots.

It is also advantageous if the tube magazines are assigned to a yarn lot, in particular the number of tube magazines required for the yarn lot is determined by the machine control. The information about the size of the yarn lot is available at the machine control, so that the number of tube magazines required can be determined most easily there.

A spinning machine according to the invention has a large number of spinning positions at which different yarn lots are spun. In addition, there are several tube magazines and a transport device in order to transport a tube from one of the several tube magazines to the spinning station. A fiber sliver is placed in a can in order to spin a yarn from it at the spinning station and then wind it onto a tube to form a spool. Each of the tube magazines and the tube in the magazine, a display device at the spinning station, a monitor at a machine control, the can at the spinning station and/or a service device are provided with a similar marking related to the yarn lot.

Such a spinning machine has the advantage that the machine can be operated more easily and the quality of the yarn lots produced can thus be improved. Errors that frequently occur, such as transporting the wrong tubes to the spinning station or loading the tube magazine with the wrong tubes, can be avoided in this way. It can easily be checked whether the right tubes, the right cans or the right parameters of the service equipment are used to produce a certain yarn lot. In particular in the case of spinning machines, in which a large number of yarn lots can be spun at the same time, this matching marking is extremely helpful. The check that the markings match can be carried out both by operators and by sensors which are arranged on the spinning machine and monitor the similarity of the markings.

There are also advantages if the marking is a color, a symbol, a pattern, a number and/or text. For example, it is possible for the individual, different yarn lots to be marked with different colors. In this case, the buttons, switches, lamps, display devices or monitors, which are provided for a specific yarn lot, light up in the same color. It is also possible for a lamp to be arranged on the can which has the same color as the corresponding yarn lot. Alternatively, it is also possible, for example, for the can to have a colored rubber band which is attached to the can in accordance with the color of the yarn batch. Likewise, instead of different colors, a symbol, pattern, number or text can be used to mark the elements of the yarn lot. This can be two or three dimensional. In any case, it is essential that this marking can be assigned to the same batch of yarn.

It has advantages if the marking is carried out by a monitor or a display, in particular a color monitor, a lamp, in particular one Multicolour LED, a switch, in particular a rotary switch with several positions, a button, in particular with color codes, and/or a label is generated. An appropriate marking agent can be used depending on the type of element to be marked. It makes sense, for example, for a monitor to show the relevant markings at the spinning position and at the machine control. It can be advantageous for the tube loader to have a rotary switch which is set to the appropriate position of the yarn lot or a button which is illuminated in the color of the yarn lot. A correspondingly marked label, on the other hand, can be advantageous for marking the sleeves.

Advantageously, sensors are arranged on the spinning machine to check the markings. If it is determined by the sensors that the markings do not match, a signal can be output to a controller, for example, with which the continuation of the work on the yarn lot is stopped. Only when the error has been rectified will work be resumed.

The device is designed according to the above description, with the features mentioned being able to be present individually or in any combination.

Further advantages of the invention are described in the following exemplary embodiments. It shows:

In the following description of the illustrated exemplary embodiments, the same reference symbols are used for features that are identical and/or at least comparable in their design and/or mode of operation, even if they are shown in different exemplary embodiments. If these are not explained again in detail, their design and/or mode of action corresponds to the design and mode of action of the features already described above.

figure 1 shows a front view of a spinning machine 1 which has a large number of spinning positions 2 . At one end of the spinning machine 1 there is an end frame 3 in which a machine control 4 is located. The machine control 4 includes a monitor 5, via which states of the spinning machine 1 can be displayed and queried. In addition, settings of the spinning machine 1, in particular with regard to different yarn lots, can be carried out via the monitor 5.

At the other end of the spinning machine 1, a large number of tube magazines 6.1 to 6.7 are arranged. In this exemplary embodiment, each sleeve magazine 6.1 to 6.7 comprises a chain 7 which stores a large number of sleeves 8. The chain 7 is driven and can move a tube 8 to a delivery point, not shown, at which the tube 8 is removed from the chain 7 and placed on a conveyor belt 9 in order to transport the tube 8 to a predetermined spinning station 2 . Such a sleeve 8 on the conveyor belt 9 is shown as an example and is moved in the direction of the arrow together with the conveyor belt 9 .

A spinning box 10 is arranged at each spinning station 2 . A sliver 11, which is deposited in a can 12 at the spinning station 2, is fed to the spinning box 10 and spun into a yarn 13 there. Then will the yarn 13 is wound onto a bobbin 14. As soon as the bobbin 14 has reached a predetermined size, it is removed from the spinning station 2 by a service device 15 and exchanged for an empty tube 8 delivered by the conveyor belt 9 . Yarn 13 is then wound up again on the empty tube 8 . After the bobbin 14 has been exchanged for an empty tube 8 and, if necessary, further maintenance work has been carried out, the service device 15 is moved in the direction of the double arrow D along the spinning machine 1 to another spinning station 2 where maintenance is required.

On the spinning machine 1 different yarn lots, for example according to figure 4 five different yarn lots I to V, are produced with different yarns 13. In principle, it is possible for a different yarn 13 to be produced at each spinning station 2 . The different yarns 13 are wound onto different sleeves 8 in order to be able to subsequently identify them. The type of sleeve 8 can later be used to identify which batch of yarn the sleeve 8 or the bobbin 14 is concerned with. If a specific yarn 13 is inadvertently wound onto the wrong tube 8, this yarn 13 would later be assigned to the wrong yarn lot. This yarn 13 would therefore be scrap. The same problem would exist if an incorrect can 12 is positioned at a spinning station 2. In this case, a wrong sliver 11 would be spun in the spinning station 2 to form a yarn 13, which also does not correspond to the specification of this yarn lot. This would also be a committee. It is also important for the service facility 15 to know at which spinning position 2 it is located, which yarn lot is being spun and accordingly which parameter settings must be valid in the service facility 15 in order, for example, to be able to attach the appropriate yarn 13 .

In order to be able to ensure that the correct tubes 8 are arranged in the tube magazine 6, that the correct cans 12 are also available at the corresponding spinning positions 2 and that the service device 15 also carries out the maintenance work with the correct parameters at the spinning position 2 and finally that the individual yarn lots can be determined in the machine control 4, it is intended to use corresponding markings 16. A marking 16 _HM (here 16 _HM1 to 16 _HM4 for four different yarn lots I to IV) is arranged on each of the tube magazines 6.1 to 6.7. This marking 16 _HM corresponds to the marking 16 _H (here 16 _H1 to 16 _H4 ) on the sleeves 8 in the respective sleeve magazine 6.1 to 6.7. The cans 12 also have markings 16 _K (here 16 _K1 to 16 _K4 ), which must correspond to a marking 16s (here 16 _S1 to 16 _S4 ) at the spinning station 2 . Depending on which spinning position 2 the service device 15 is located at for its work, in this exemplary embodiment the service device 15 also has a corresponding marking 16 _SE , which corresponds to the spinning position 2 and its marking 16s on a display device for the spinning position 2 or the marking 16 _K on the can 12. The machine control 4 or its monitor 5 also has a marking 16 _M (here 16 _M4 ) for configuring the individual yarn lots. On the machine control 4, the marking 16 _M can be assigned to a specific yarn lot and parameters, such as spinning speed, yarn number, yarn quantity, etc., can be defined for this yarn lot.

Different markings 16 are provided to distinguish between the individual yarn lots, each of which is assigned to a specific yarn lot. Symbolic is in figure 1 a circle with a corresponding fill pattern is shown as marking 16 in each case. However, it can also be a lamp, for example an LED, which lights up in a specific color. It is also possible for the marking 16 to be a specific text, a bar code, a colored or patterned rubber band around the pot, or the like. The type of marking can also differ, the only important thing is that they have a clear common characteristic, such as the same color. Markings 16 on the sleeves 8 are preferably applied in such a way that they are still recognizable after the yarn 13 has been wound around them and thus identify the bobbin 14 at the same time. How out figure 1 can also be seen, the two left sleeve magazines 6.1 and 6.2 are provided with the same marking 16 _HM1 and thus belong to the same yarn lot I. The same applies to the three middle sleeve magazines 6.3 to 6.5. These are also marked with the same markings 16 _HM2 and accordingly indicate another yarn lot II. The sleeve magazines 6.6 and 6.7 are assigned to different yarn lots III and IV and accordingly have markings 16 _HM3 and 16 _HM4 . Corresponding markings 16 _H1 , 16 _H2 , 16 _H3 and 16 _H4 are attached to the sleeves 8 in the sleeve magazines 6 . Corresponding markings 16 can be found again on the corresponding cans 12 and spinning positions 2. After the service device 15 is currently working on a spinning position 2 with the can marking 16 _K2 , the service device 15 is also provided with the marking 16 _SE2 .

As can also be seen from the illustration, the number of tube magazines 6 or spinning positions 2 assigned to the respective yarn lots can deviate from one another. The assignment can be made via the machine control 4 and depends, for example, on the production speed of the spinning positions 2 and the size of the respective yarn lot.

With a sensor 19, which is shown here, for example, on the service facility 15, the existing markings 16 can be checked. If an error is detected, the sensor 19 sends a corresponding signal to a controller.

In figure 2 a rotary switch 17 is shown symbolically. The rotary switch 17 can be set to a specific marking 16.1-16.5. Such a rotary switch 17 is arranged on the sleeve magazine 6, for example and causes a corresponding allocation of the tube magazine 6 to a specific yarn lot. By setting the rotary switch 17, a signal can be connected to the machine control 4, which determines that the corresponding tube magazine 6 is assigned to precisely this set yarn lot and when a tube 8 from this yarn lot is requested, the corresponding tube magazine 6 is actuated to dispense a tube 8.

figure 3 symbolizes a button 18. The button 18 can activate different markings 16, here marking 16.3, by pressing it several times. It is possible that different lamps light up or that the button 18 controls a multi-color LED and the corresponding color lights up. In this exemplary embodiment, eight different batches are possible, so that eight different markings 16.1 to 16.8 can also be set.

In figure 4 the monitor 5 of the machine control 4 is shown schematically. The selection of the markings 16 and the assignment of these markings 16 to specific lots can take place here. It can also be determined for which game, here game IV, which is shown in greater detail, the parameters are to be changed.

The present invention is not limited to the illustrated and described embodiments. Modifications within the scope of the patent claims are just as possible as a combination of the features, even if they are shown and described in different exemplary embodiments.
