Abstract
Description
- The present invention relates to a tube for tracking a reel, a winding apparatus with a reel tracking device and a winding method comprising the tracking of a reel.
- As known, the thread or yarn produced is wound about a tube to form a reel in winding systems. It is worth noting that the term "thread" or monofilament or continuous filament means a single filament or continuous bave (e.g. in the case of silk, artificial or man-made fibers), while the term "yarn" means the set of fibrils of variable length which are parallelized and joined by twisting. Hereinafter, we shall use either term indiscriminately, meaning that the applications of the present invention are not limited to one type or the other. The reel is made by winding the thread of a spool after it was unwound from the spool and any defects were removed. In any case, the thread is wound about a tube which may have various shapes and materials. Cylindrical or conical tubes made of plastic or cardboard are typically used.
- Winding machines have a number of winding units, each of which forms a reel by appropriately accumulating the yarn on a tube. The tubes are positioned in baskets above the winding head.
- At the beginning of the winding process, the doffing cart used by the reeling machine takes a tube from the basket and positions it on the winding head. At the end of the winding process, the reel, consisting of the tube plus the deposited yarn, i.e. wound, on it, is removed from the winding unit by the doffing cart.
- In particular, the doffing cart is positioned on the winding unit and removes the newly formed reel by loading a new tube on which the winding unit will form a new reel.
- The known solutions do not provide any tracking of the reels formed by each spinning unit; in other words, the reels, once formed, are stacked in baskets as a function of the production batch.
- In any case, during the successive steps of processing of the yarn, which must be unwound from the reels or dyed, for example, the information on the origin of the reel is lost.
- In other words, the information about manufacturing date, production batch, winding machine and/or winding unit which produced the individual reel is lost.
- The loss of this information does not allow, for example, to be able to trace back to the manufacturing batch and/or the winding machine or winding unit which generated the individual reel. This information could be extremely useful, for example, to be able to retrace the criticality of a production batch, of a winding machine or even of a single winding head or unit.
- Furthermore, it is not possible to catalog the manufactured reels, for example, in order to differentiate their destination as a function of the characteristics of the manufacturing batch (or unit) itself.
- The need is therefore felt to solve the drawbacks and limitations mentioned above with reference to the prior art.
- Such a need is met by a tube for tracking a reel according to claim 1, by a winding apparatus according to claim 7 and by a winding method according to claim 21.
- Further features and advantages of the present invention will be more comprehensible from the following description of preferred embodiments given by way of nonlimiting examples, in which:

- With reference to the aforesaid figures,
reference numeral 4 indicates a winding apparatus, as described in greater detail below. - It is worth noting that the present invention preferably but not exclusively applies to a winding apparatus in which the thread unwound from a spool is wound on a reel after any defects have been removed in a winding unit. Indeed, the present invention can be applied to a generic spinning apparatus, in which the thread is made, e.g. with air-jet or open-end technique, and then wound on a tube, in order to keep track of all the processes undergone by the thread itself (as described in greater detail below).

identification device 44 is arranged along a prevailing direction parallel to a generatrix straight line of thetube 8. - According to a further possible embodiment, the
identification device 44 is arranged along a prevailing direction perpendicular to a generatrix straight line of thetube 8. - In general, the position and orientation of the tag, i.e. of the

The data acquisition system may also be connected to aremote terminal 84 which can be used by the user to display any further information provided by thedata acquisition system 76. - The operation of a winding apparatus according to the invention will now be described.
- In particular, the winding apparatus according to the present invention works by implementing a winding method comprising the steps of:
- providing at least one
tube 8 provided with anidentification device 44 adapted to uniquely identifying saidtube 8, wherein saididentification device 44 is a radio frequency identification (RFID) device comprising an electronic identification code (EPC), - loading said
tube 8 onto a windingunit 56 and identifying theidentification device 44 by means of areading device 68 of theidentification device 44 of thetube 8, - storing the information relating to the operations carried out by the winding
unit 56 on the yarn wound on saidtube 8 to form areel 12 in a database ordata acquisition system 76, - associating in said database or
data acquisition system 76 theidentification device 44 of thetube 8 with the information relating to the operations carried out by the windingunit 56 on the yarn wound on saidtube 8. - More in detail, the method may comprise the step of: applying the RFID tags on the
tubes 8 to be loaded on the baskets of thewinder units 56, each tag having a unique EPC;
loading anew tube 8 on the windingunit 56 by means of thecart 60, and during this process writing the following information on the identification device 44: - a) The serial number of the winding
apparatus 4, - b) The serial number of the winding
unit 56 in which the winding process of thespecific reel 12 will take place on thespecific tube 8. - (c) The date, hour, minute, second of loading of
tube 8 on windingunit 56. - Then the
cart 60 communicates the EPC code of the identification device of the loadedtube 8 to the windingunit 56. - Thus, the winding
unit 56, at the end of the winding process of thereel 12, communicates the statistics, the alarms, the types of cuts made during the formation ofreel 12, to the processing and control unit of the windingequipment 4 using the EPC code as a unique key to identify the collected information. - The processing and control unit of the winding machine locally accumulates the data communicated by the winding
units 56 concerning the formation of thereels 12 uniquely identifying them by virtue of the EPC provided by eachtube 8. - The processing and control unit sends the collected data to the external
data acquisition system 76, which stores the data related to the formedreels 12, again using the EPC identification code. Thus, an external acquisition system makes it possible to retrieve the data related to the formation of aparticular reel 12 according to the EPC. - Finally, by using a portable reader 80 (e.g. smartphone with RFID reader system) it is possible to read the tag or
identification device 44 of aparticular reel 12 and by means of the EPC code to retrieve the data related to thatparticular reel 12 using the data present in thedata acquisition system 76. - The data acquisition system also makes it possible to give feedback on any problems which may have occurred during the use of
reel 12 itself in weaving or, for example, in dyeing or knitting or more generally in the subsequent steps of processing of thereel 12. - As can be appreciated from the description above, the present invention makes it possible to overcome the drawbacks of the prior art.
- In particular, the present invention makes it possible to overcome the limits of known winding systems.
- Indeed, the individual reels can be traced in a complete and exhaustive manner so as to reconstruct their entire history, starting from their formation. It is, therefore, possible to keep track of the manufacturing batch (date and location), the winding machine and also the individual unit or winding head.
- Moreover, the stored information makes it possible to uniquely identify the single reel and to reconstruct, for example, all the operations carried out by the head on the single reel, such as the number of cuts (and their splices), the exact length, and so on. This information can be read back by the user to reconstruct the history of the reel.
- It is worth noting that the tag does not necessarily store all the information related to the making of the single reel but it can only store the (unique) identification code of the reel itself which will be associated to a database which contains additional information about, e.g. the winding machine, the single winding unit, the number of splices/cuts and so on.
- The reels can then be classified with a ranking or categorized in such a manner that they can be used for different purposes, for example, because of the respective quality resulting from the respective forming history.
- It is, therefore, possible to catalog/discriminate reels of different type/quality for different uses. For example, the reels which have undergone a greater number of cuttings/reattachments may be used for weaving fabrics which are not intended to be visible in subsequent use (such as the cuffs of a shirt).
- On the other hand, the reels which have undergone fewer cuttings/reattachments may be used for weaving parts of fabrics intended to be always in view in the subsequent use, such as fabrics for shirt front parts.
- Furthermore, the reels with a greater or lesser number of interruptions/reattachments may be destined to a different step of dyeing; for example, it will be possible to change the bath immersion time in the case of yarn-dyed reels.
- Another criterion according to which to modify the immersion time may be the exact length of the individual reel which obviously modifies the density of the thread.
- Alternatively, it is possible to catalog reels with different thread winding densities because they come from winding units with a specific type of thread guide.
- Furthermore, the information stored on the single reels may be useful to reconstruct the operating mode of the winding machine and the single winding heads/units, so that preventive maintenance can be carried out on the rotor heads/units themselves, for example.
- A person skilled in the art can make numerous changes and variants to the winding apparatuses and methods described above, all contained within the scope of protection defined by the following claims in order to satisfy contingent and specific needs.
