Description

The invention relates to a method and device for assigning yarn and / or machine-related data to bobbin tubes of spinning machines with codes on the bobbin tubes with at least one reading device, a memory and a computer.

It is known to provide devices (so-called pegtrays) used for the transport of coils and sleeves with automatically readable, in particular magnetic, codes, by means of which information about the type and origin of the sleeve located on the devices or of the material wound on this sleeve can be given (DE-OS 36 03 002).

However, the coding of these devices has the disadvantage that the coded identification is no longer applicable in the case of an exchange between the coil and the device caused by manual intervention.

The prior art also includes a method for sorting yarns on cops and sleeves which can be used, the sleeve being provided with detection rings which are spaced apart (DE-OS 27 12 964). With the big one Number of sleeves to be used, this arrangement is very expensive.

It is also known from the prior art to provide sleeves or windings of cops with markings from which the type of yarn can be identified. The marking can be removed because the sleeve can be spun with another type of thread the next time it is used. If the label is attached to the winding, it disappears automatically when the yarn is rewound. Such recognizable labels have the disadvantage, on the one hand, that they require the removal operation and, on the other hand, there is the possibility that the labels can be removed unintentionally, so that precise responsiveness is no longer given.

In contrast, the present invention has for its object to provide a method and an apparatus for assigning yarn and / or machine-related data to bobbin tubes of spinning machines, in which the aforementioned error possibilities are properly eliminated.

This object is achieved in that each coil tube is assigned an individual, permanent, machine-readable coding, that the reader that detects the coding of the coil tube detects codings that are reported to the computer, that the computer connects the codings reported with the data to be stored with respect to the coil tube and that transmits the data record thus formed into the memory and that at least part of the data record can be called up from the memory via the address of the sleeve coding or the other data.

The present invention thus provides each individual sleeve with an individual, permanent, automatically readable coding (sleeve number). It is here it can be seen that this tube number says nothing about the type of yarn wound on the tube and the origin of the tube (for example machine, spinning unit number, etc.). However, according to the invention, this additional, mandatory information is not attached to the sleeve, but is assigned externally in the computer to the number of each sleeve and the data record thus formed is stored under the address of the individual sleeve number. The changeable data are therefore expediently only created and treated as software; deleting them is easy and cannot be done involuntarily.

The present invention therefore relates not only to the feature of machine-readable individual numbering of the tubes, but also to the representation of the formation of the data sets from individual tube numbers and yarn and / or machine data and their storage and other handling by a computer.

In particular, it is provided that each sleeve is identified with an individual, permanent coding, for example in the form of a bar code known per se or as machine-readable numbers and / or letters. After defining the identification to be given, the respective data record "sleeve coding + identification feature" is logged. This protocol remains stored in a memory, which is arranged, for example, in a compact, stationary unit, until the interest in the feature identification has expired. This compact, stationary unit is expediently arranged outside the reading device and can include the computer, the memory, an input device and an output device.

The coding is advantageously attached to one of the unwinded end regions of the sleeves. If a bar code is used, the bars can be used as a perimeter rings be formed; they can then be read independently of the rotational position of the sleeve, a swiveling read head being required in this embodiment. If you use axially parallel jacket lines as the bar code, a stationary reading head must be used for reading, and the sleeves must be rotated for reading.

Depending on which characteristic data are logged and saved, questions regarding the material contained, the spinning point produced, the quality of the tube, etc. can be answered in the further course of the processing of the spools. The saved log is deleted when the tube is emptied and made available for a new winding process.

The recording of the protocol can also be done, for example, by at least one reading device traveling along the spindles, which reads the individual codings of the sleeves and sends them to the computer, which combines them with the other desired data and reports them to the memory. According to another embodiment, it is advantageous to read the individual sleeve codes after they have been removed from the spindle when the sleeves are moved past a stationary reading station by a transport device.

• Fig. 2 eine schematische Seitenansicht einer weiteren Aus­führungsform der Erfindung;
• Fig. 3 und 4 zwei verschiedene Ausführungsmöglichkeiten der Strichcodierung.

The invention is described below with reference to exemplary embodiments shown in the drawing. The drawing shows:

• Figure 1 is a schematic plan view of a spinning machine according to a first embodiment of the invention.
• 2 shows a schematic side view of a further embodiment of the invention;
• 3 and 4, two different ways of executing the bar coding.

According to FIG. 1, a spinning machine, for example a ring spinning machine, has a conveyor belt 20 on both sides, onto which cops 2 finished in the machine are attached, for example by a bobbin changing device known per se. At the end frame 21 of the machine are two copes 2 facing on the conveyor belts 20 readers 3 and 3 ', which the copes are moved past when moving the conveyor belt and which detect the codes of the bobbin tubes 2 and forward them to a computer for further processing.

2, which represents another embodiment of the invention, the reading device 3 is arranged on a carriage 14 which can be moved along the spinning machine 1. This carriage 14 has two superimposed rollers 17 and 18 which act on both sides of a rail 19 which is stationary on the spinning machine and thereby guide and move the carriage 14 and thus the reading device 3. This reader 3 detects codings of the coil sleeve 2.

A computer 4, an input device 5, a memory 6 and an output device 7 are arranged outside the reading device 3 in a compact, stationary unit 15, these unit 15 being connected to the reading device 3 via a data path 16.

From Fig. 3 and 4 it can be seen that, for example, a bar code can be used as coding, which are arranged according to FIG. 3, for example, as circumferential rings 8 or according to FIG. That unwrapped end area lies outside the area 13 of the bobbin tube 2 covered with thread material.

In the embodiment according to FIG. 3, the reading device 3 can be displaced in the direction of the coil axis over at least a region of the circumferential ring bar coding 8, for example in that the reading device is designed to be pivotable, whereby the region lying within the arrows can be scanned. The coil sleeve 2 is in this case mounted on a plate 9 which is movable within a guide 10. The circumferential ring bar code 8 is located between the area 13 covered with thread material and the bobbin plate 9.

In the embodiment according to FIG. 4, again a bobbin plate 9 is used, with the surface line bar code 8 'also being located between this plate 9 and the area 13 of the bobbin tube covered with thread material. In this embodiment, a rotary drive is provided for the bobbin 9 with a drive roller 11 and two counter rollers 12. Thus, the bobbin tube 2 can be rotated, whereby the surface line bar code 8 is provided for reading for the reader 3 '.

With regard to the arrangement of the reading device, there are two variants, namely that the reading device is designed to be movable relative to the sleeves to be scanned and, secondly, that the reading device is arranged in a stationary manner, the coil sleeves 2 provided with coding being guided past the reading device by means of a transport device.

All embodiments have in common that each coil sleeve 2 is assigned an individual, permanent, machine-readable coding 8 or 8 ', and that the coding of the coil sleeve reading device 3 or 3' reports the detected codes to the computer 4. The computer 4 connects the codings 8 and 8 'it reported to him via the input 5 entered data to be stored with respect to the coil sleeve 2, the data record thus formed being transferred to the memory 6. At least part of the data record can then be called up from the memory 6 via the output device 7 via the address of the sleeve coding or the other data.

The process sequence according to the invention can be described as follows:
When a take-off is completed on a spinning machine 1, the individual numbers of the spun sleeves 2 are read and transmitted to the computer 4. In this computer 4, these sleeve numbers are supplemented with other data relating to data records. These other data are supplied to the computer 4 by an input unit 5 in which they have been entered and from which the computer 4 retrieves them. This data can consist of the following:
The machine number from which the spun bobbins originate and / or - if this machine number does not clearly identify the type of yarn with which the bobbins are spun (which is the case when changing lots) -
the yarn parameters (fineness, quality, twist per meter) and / or
the date of manufacture and / or
other information of interest.

The spinning station number from which the cops originate is generally a consecutive number which the computer 4 itself can form.

For example, this results in the following system: t n n + 1 n + 2 n + 3 n + 4 u 31618 20218 00731 12874 03681 v 03 03 03 03 03 w m m + 1 m + 2 m + 3 m + 4 x 40 / E / 016 40 / E / 016 40 / E / 016 40 / E / 016 40 / E / 016 y 880122 880122 880122 880122 880122 e.g. .... Here mean: t = counting or calculation process u = read sleeve number, supplied by reader 3 v = machine number, called or forwarded by input device 5 w = spinning station number, formed in the computer 4 x = yarn parameters retrieved from input device 5 y = date, formed in the computer 4 or retrieved from the input device 5 z = further data. n, m = whole natural numbers

The values u plus at least one of the rows v to z of each column represent a data record which the computer 4 supplies to the memory 6. It is possible that the aforementioned data can be encrypted accordingly.

The above-mentioned stored data can be used in different ways: If bobbins with different types of yarn are to be mixed on the transport route to downstream machines, for example cross-wound bobbins, and then sorted again, reading devices can be arranged in the sorting points that read the individual tube numbers of incoming bobbins. Inquire at the address of this individual tube number at the store 6 which type of yarn is wound on these tubes and accordingly control the further transport of the cop.

If, for example, it is to be determined for a particular cop when it was manufactured on which spinning station because it contains defective yarn, for example, and the corresponding spinning station is to be located, the individual number of its bobbin tube 2 can be read by means of a reader and, for example, by means of a reader Display provided input device 5 this information can be queried from the memory 6 at the address of this sleeve.

Based on the individual sleeve numbers, statements about the life of sleeves can also be made very easily if the date of their commissioning is saved and compared with the date of their sorting out.

The machines downstream of the spinning machine 1, on which the windings of the cops are unwound, can be equipped at the point at which empty-wound tubes are delivered with a reader that reads the individual numbers of empty tubes and informs the computer 4. Messages arriving in this way cause the computer 4 to delete the associated data record, since the stored assignment of individual sleeve numbers and other data no longer exists. In this case, the memory 6 can also serve as inventory management for the amount of yarn present for a certain type of yarn if the memory 6 is queried at the address of this type of yarn for the number of cops wound with it.

It is also possible to leave the data record in existence until it is overwritten by a current data record after rewrapping this sleeve, at the address of the individual sleeve number concerned.

The computer 4 is connected directly to the output device 7, via which it can be used by other machines, devices, devices, etc. Can transmit commands or data. For example, it can be provided that, after the creation of data records for the cops of one machine has been completed, it issues commands to the reading devices of another machine, the finished copes of which are ready for reading the individual sleeve numbers of their cops, to start the reading process or to carry out further processes Taxes.

In any case, the invention creates the possibility of logging the thread material wound on the core spools 2 with regard to the type of material, fineness, rotation per meter and other data, with the individual core coding being stored together with the material identification after the windings have been completed on the core spools . It is also possible to save the spinning station on which the individual tubes have been wound. The recording of the protocol can be done by readers 3 or 3 ', which are either stationary or movable, read the individual codes of the sleeves and give them to the computer 4, which combines them with the other desired data and forwards them to the memory 6. The overall result is a very functionally reliable device with extensive application possibilities for connecting and networking the individual machine types within a spinning system.
