MULTIFUNCTIONAL DEVICE FOR THE SUPPLY OF THREAD WITH CHIP

OBJECT OF THE INVENTION

The invention, as stated in the present specification, refers to a multifunctional device for the supply of thread with chip, especially in the sewing of a garment during or after its realization, which contributes, to the function to which destin, advantages and characteristics, which are described in detail below, which represent a remarkable novelty in the current state of the art.

The object of the present invention lies in an electrical / electronic device whose purpose is to be configured as a practical means to provide the supply of wires with chip, particularly wires with RFID chip (Radio Frequency Identification or radio frequency identification) and NFC antenna (Near Field Communication Near field communication) of those that are incorporated into garments, whose structure incorporates means to dispense said threads already cut, checked and positioned so that their collection and placement is facilitated to the seamstress that has to incorporate them, and which, optionally, also has means for recording the desired information on the chips during the thread delivery process itself. Preferably, the device allows the introduction of said yarn with chip in the seam of a garment during its manufacture through compressed air supply means.

FIELD OF APPLICATION OF THE INVENTION The field of application of the present invention is part of the industry sector dedicated to the manufacture of electrical-electronic devices and devices, specifically covering the field of chip wires, as well as the field of industry textile.

BACKGROUND OF THE INVENTION

The threads that carry embedded RFID chips with antennas along them are known in the market. A portion of said thread with a chip and an antenna is introduced somewhere in a garment (hem, neck, sleeve ...), replacing traditional RFID tags, which are seen and can be easily removed. The fact that it is a thread is an advantage over labels, since it makes it difficult for the user to find and extract it. The RFID chip can be used to incorporate information, although it mainly has an alarm function to prevent shoplifting.

The thread, in addition to the chip, bears visual marks that indicate where it should be cut so that the portion of the thread to be incorporated in the garment contains a chip and the corresponding antenna.

The thread can be supplied in two ways. A first way is already cut into sections that contain a chip and an antenna. In this way the garment maker must take a thread one by one from the container and place it correctly on the piece of clothing where it should be fixed.

The thread can also be delivered as a bobbin. In this case the seamstress must cut the thread correctly, so that it contains only one chip and an antenna, and place it on the piece of clothing. The invention is directed to this case.

The problem is that the wire is difficult to place since it needs to be placed straight or practically straight so that the antenna fulfills its function. It should be noted that when the thread is bent, the chip does not work.

The problem is also that the supply of the thread to the seamstress is difficult, since, being a thread, it easily bends and is difficult to handle.

The objective of the present invention is, therefore, the development of a device specially designed to avoid said problem and make the supply of said thread the optimum to facilitate its collection to the seamstress and to be able to place it properly in the garment, making the operation is carried out in less time, which, in turn, has an impact on the time invested in the manufacture of garments and the reduction of defects.

Another object of the invention is to provide, at the same time, a multifunctional device so that, among other functions, it comprises means for checking the correct operation of the thread before its placement, avoiding the incorporation of defective threads in the garments.

Another problem is the difficulty of manipulation and introduction of the thread in the seam of a garment without wrinkling or being misplaced. This problem requires a special skill on the part of the seamstress to be able to perform the task of introducing the thread into the seam of the garment quickly and correctly, which can therefore lead to a slowdown of production that impacts costs of manufacturing. Another objective of the present invention is, therefore, the development of a device that provides means for supplying the wires in an ideal manner, that is, cut with a chip, checked and in the correct position, also providing the means for inserting said wires. directly in the seam of the garment at the time of making it when making the garment and being able to do it only when necessary, since logically, it is only included in one of the seams, not in all.

On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other device for the supply of thread with chip or any other invention of similar application that presents some is unknown. technical and structural characteristics equal to or similar to those presented here.

EXPLANATION OF THE INVENTION

The multifunctional device for the supply of wire with chip that the invention proposes is thus configured as a remarkable novelty within its field of application since, according to its implementation, the aforementioned objectives are satisfactorily achieved, the characterizing details being make it possible and conveniently distinguish it from the final claims that accompany the present description.

Specifically, what the invention proposes, as indicated above, is a device constituted to supply threads with embedded RFID chip, of which they are incorporated into garments, usually as an alarm means, facilitating the delivery of said threads to personnel that you have to place it, usually seamstresses, so that they can take it already cut and in the appropriate position and having been checked for proper operation or discarded if it is not suitable. Alternatively, the device incorporates means for inserting the thread directly into the seam of the garment during the sewing of the garment with a sewing machine or even once it has been carried out, said insertion of the thread in the sewing taking place, thanks, preferably to means for driving compressed air.

For all this, the device incorporates a set of electrical and electronic means that, controlled by a computer system implemented in a PLC (programmable logic controller), make such delivery possible starting from a coil where the wire is in continuous. Alternatively, they make its insertion possible without having to manipulate it thanks to a compressor group that drives it through a set of tubes associated with said means.

Thus, in a first phase, the thread accesses from the bobbin a first area of the device where the correct placement of the thread is carried out to perform the cut correctly and to ensure its dispensing in the correct position, which is preferably carried out by means of rollers motorized that control the movement of the thread and introduce it in a first section of guide through which runs flat between two treadmills, and after which a contrast sensor is preferably included that detects the marks of the thread that indicate where to cut the thread . In that first zone the thread is cut in the correct portion. For this purpose, said area preferably comprises a knife or a shear, among other cutting means.

In the event that the thread is not correctly placed, the computer system that controls the drive of the device moves the rollers to correct the situation of the thread.

In a first family of embodiments, the thread is cut and passes to a second guide section in the second area of the device towards the exit where the thread is partially accessible to the seamstress who can stretch it in the ideal position to proceed to place it in the garment. The thread in this phase is delivered in a straight way, which facilitates its correct placement.

In a second series of embodiments, a second tensioner faces the cut wire towards a motorized roller that is protected inside an aluminum receptacle, which acts as a means to move the thread as it pushes it towards the cutting means located below, which, constituted by a shear, cut the thread in a segment that contains a chip and its antenna.

The device incorporates means for checking the operation of the chip. Said means may be in different positions detailed below, including duplicates to verify that it continues to function properly after handling.

Thus, in the second series of embodiments, the device incorporates the means for detecting the correct operation of the chip, consisting of a sensor for detecting and checking RFID chips. The wire passes in front of the means of detecting the correct functioning of the chip inserted in a tube, which we will call a conductor. Compressed air is introduced to said conductive tube which moves the wire through the conductive tube to the selector. During the thread path, the selector allows compressed air to exit through another duct. When the thread reaches the selector, the selector, if the thread chip works correctly, allows to pass the a tubular guide, preferably metal. Otherwise, the selector, if the chip is defective, rejects it by closing the passage of the air tube so that it does not pass to the guide, and allowing the exit of this from the device through a conduit for this purpose.

It should be noted that, preferably, the evacuation duct acts as an outlet for compressed air from the conductive tube so that it exits during the first phase of air injection, since it is important that the air that exists prior to the wire leaves the system, since in otherwise, the thread would wrinkle inside said tube and not advance. Once said air prior to the thread has already left and said evacuation duct is closed.

For its part, said tubular guide consists of a thin conduit, preferably metallic and preferably of aluminum, which has a curved configuration and of sufficient length to allow the introduction of the entire length of a wire with chip inside a seam in the time to make it on a garment with the machine to which the device is attached. Also, preferably, the distal end of the metal tubular guide, which provides the introduction of the thread into the seam driven by compressed air, has a sharp tip that allows the thread to be introduced into previously closed seams.

It should be noted that the machine in which the second series of embodiments of the device of the invention is installed is preferably a machine that performs overlock or overcast seams, which, as is known, is a type of seam that is made on the edge of one or two pieces of fabric to define the edge, but also to encapsulate it, so that the thread will be introduced in said encapsulation, although this does not imply a limitation.

Preferably, in addition, the device carries an adapter so that it can placed on one side of a standard sewing machine. There are already other types of devices that perform other functions and that are placed on the sewing machines using existing adapters for this purpose in the market. And, advantageously, said adapter is incorporated in a tilting fastener that allows it to be easily removed from the area of handling of the garment when it is not necessary to introduce any thread with a chip.

Optionally, the device of the invention also includes means for applying an adhesive layer to the thread so that it is fixed to the garment where it should be placed.

Also, according to an alternative option of the invention, the detection and verification sensor of the RFID chip will also be used as a recorder, that is, the thread chip will be configured with information such as size, model, batch or other. This reading configuration can be modified by the user through a touch screen equipped with the corresponding media.

Finally, it should be noted that all the electronics, sensors, electric motor and electromagnet are controlled by a PLC computer system with a power supply that is incorporated in a separate module.

In any case, it should be mentioned that the described arrangement of the different means of operation of the device may suffer variations in the order of position of each of them, as long as its function remains effective.

In summary, then, the device is intended to dispense the thread cut into functional segments that include an embedded RFID chip of proven operation and in a straight position to pick it up and handle it as appropriate, for which it essentially comprises:

• means for moving the thread from a bobbin

• guiding means that place the wire in a straight position, in the proper position to be handled, preferably constituted by motorized impellers and guides;

• detecting means that check the position of the RFID chip in the thread that detects the cut mark contained in the thread preferably formed by a contrast sensor,

• means for checking the operation of the RFID chip preferably formed by a chip detector sensor,

• cutting means preferably consisting of a blade;

• means for supplying the segment of thread cut with a functional chip, for example, partially ejecting it so that it can be easily picked up, formed by the exit guide, or by introducing it into a seam, by a conductive tube, by means of compressed air injection, and a tubular guide (22);

• optionally means that discard the thread segment, for example if it does not pass the check or if the operator decides to dispose of it for another reason, preferably consisting of a scrap thread guide or by a suction means and a deposit of discarded threads, or a selector that derives the defective wires to an evacuation duct; Y

• computerized control means of all electrical and electronic components that include said means, constituted by the PLC. The means of checking the operation of the RFID chip can be located before the cutting means and before the means that discard the thread segment. In this specific embodiment if the RFID chip detector sensor has verified that the thread chip is working correctly, the cut wire is led to the seamstress by means that partially eject the segment of thread cut with a functional chip so that it can be easily picked up. , led by the exit guide. However, if the thread is incorrect, that is, if the detector sensor of the RFID chip has verified that the thread chip does not work properly, the cut wire is taken to a waste container through a third section of guides provided to the effect on said second zone of the device.

In another preferred embodiment, the means for checking the operation of the RFID chip are located after the cutting means such that the seamstress must manually reject the non-functional thread segment.

In another preferred embodiment, the means for checking the operation of the RFID chip are arranged on the working area of the seamstress in such a way that they are able to check the operation of the chip once it is fixed on the garment. The means of checking the operation of the chip are manually operated so that said means of checking do not work continuously but on time when the seamstress so desires. In this embodiment, the effect achieved in checking the operation of the RFID chip once it is fixed on the garment and can no longer be damaged by the action of the sewing machine (for example, by pricking the chip with the sewing needle). These means of checking the operation of the chip may be duplicated, before and after placement in the garment. The multifunctional device for the supply of yarn with chip described consists, then, in an innovative structure with characteristics unknown until now for the purpose for which it is intended, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity requested.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a non-limiting embodiment of the multifunctional device for the supply of chip wire of the invention can be observed, which comprises the parts and elements that are indicate and describe in detail below.

Thus, as seen in Figures 1 to 3, the first preferred embodiment of the device (1) of the invention consists of a support structure (2) in which, coupled thereto, comprises a conveyor (19) , in this case two motorized impellers (3) that rotate in opposite directions determining the displacement of the thread (4) that comes from a bobbin (5). The support structure (2) comprises a set of electrical and electronic means, controlled by a computer system implemented in a PLC (30). The thread (4) part of the bobbin (5) and runs pressed between both motorized impellers (3) in one direction or another, normally to advance inserted in a first section of input guide (6) of the thread. The input guide (6) is formed by two treadmills between which the wire (4) travels straight, a sensor detecting the chips (7) RFID of the wire (4), which checks its position and operation, located on said input guide section (6), a contrast sensor (8) which, located next to a knife (not shown in the figures) after the input guide section (6), detects the signal of the thread (4 ) to cut the same at the marked point, a section of exit guide (9) of the cut wire (4), also constituted by two treadmills between which said thread (4) moves, in this case until emerging by its exit end, and a section of guide of discarded thread (10) that, also formed by two treadmills between which the thread moves, is arranged obliquely after the end of the section of guide of entrance (6) and the leads to a deposit (1 1) of discarded wire when checking the chip detector sensor (7) RF Thread ID (4) does not take it for granted.

With this, the operation of the device is as follows: First, the thread (4) of the bobbin (5) is driven by the motorized rollers (3). Then, the chip detector sensor (7) RFID checks the alarm functionality of the chips. The contrast sensor (8) verifies the thread cut point for proper alarm operation. The functional thread (4) is cut and dispensed so that it is easily accessible for handling. In the event that a thread is not functional, it is discarded by sending it to a tank (1 1) of discarded thread. Preferably, the support structure (2) also has a tensioner (12), in this case a impeller, which regulates the tension of the wire (4) coming from the bobbin (5) before passing through the motorized impellers (3), as well as with an adapter (13) to be placed on the side of a standard sewing machine (26). Optionally, the device (1) also comprises, for example incorporated in the support structure (2) at the end of the exit guide section (9), means suitable for applying an adhesive layer to the thread (4).

Similarly, the sensor detecting the RFID chips (7) of the wire (4), in addition to checking its position and operation, also acts as an information recorder on the thread chip (4).

In any case, all the mentioned electronic and electrical elements are controlled by a PLC with a suitable power supply (not shown in the figures), incorporated in a separate module to the support structure (2), to which they are conveniently connected .

In the second preferred embodiment, represented in Figures 4 to 6, the device (1) of the invention is designed to preferably be installed next to the sewing machine (26) with which the seams are made to introduce the thread (4 ) in them. This embodiment ensures the supply of the thread (4) from a bobbin (5) where it is in continuous and its insertion in the seam of the garment without manipulating it by means of compressed air supply means provided by a compressor (12) through a set of tubes (13, 14). This embodiment also comprises a contrast sensor (8) that detects the signal in the thread or chip, cutting means, which in this case is a shear (15), one or more sensors detecting the RFID chips (7), a discarded thread guide (10), and insertion means (16) in the seam.

In particular, the support structure (2) of this embodiment preferably comprises: - a first tensioner (17) that passes the thread (4) from the bobbin (5) to a tensioner (12) that helps guide it in front of a contrast sensor (8) which, as a means of visual detection, checks the position of the thread marks (4) that indicate the position of the chip;

- a second tensioner (18) that faces the thread (4) towards a conveyor (19) which, as a means of movement, advances the thread (4): The conveyor (19) in this case is protected inside a receptacle ( 20) resistant, generally metallic, preferably of aluminum, pushing it towards the shear (15) which, next, constitutes the cutting means that cut said wire (4) in a segment containing a chip and its antenna;

- a sensor for detecting the RFID chips (7) located behind said shear (15), as means of checking the operation of the chip of the thread (4) already cut;

- a conductive tube (13) to which compressed air is introduced from a compressor (12) that moves the wire through the conductive tube (13) to a selector (21). During the thread path, the selector (21) allows compressed air to escape through an evacuation duct (14). When the thread (4) reaches the selector (21), this, if the thread chip (4) works correctly, allows the wire to pass to a tubular guide (22), preferably metal. Otherwise, the selector (21), if the chip is defective, rejects the thread (4) closing the passage of the air tube so that it does not pass to the tubular guide (22), and allowing the exit of this from the device to through a conduit for this purpose, such as the evacuation conduit (14).

- and a tubular guide (22), preferably metal, located at the opposite end of said selector (21) and with which the thread (4) is introduced into the sewing driven by said air.

Preferably, the tubular guide (22) is an aluminum conduit that has a curved configuration, to redirect the thread (4) from a starting position, which in the figures is perpendicular to the direction of seam advance, to a parallel position to said direction of advance of the seam, as seen in figure 5, with a length equal to or greater than that of the thread segment (4) cut with chip to be inserted, to allow the introduction of the entire length thereof inside the seam.

Preferably, the tubular guide (22) is anchored to the sewing machine (26) coupled in a universal adapter (23), of those existing in the market for sewing accessories, which allows its placement next to the needle area ( 24) of said machine for introducing the thread (4) during sewing, which adapter (23), preferably, is incorporated in a tilting support (25) that allows it to be removed when it is not needed.

On the other hand, also preferably, the distal end of the tubular guide (22) has a pointed tip (22a) for introducing the thread (4) into previously closed seams. Said pointed tip (22a) is clearly seen in Figure 6.

Describing sufficiently the nature of the present invention, as well as several ways of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of for example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its fundamental principle.
