DESCRIPTION

DEVICE FOR SUPPLY AND INSERTION OF THREAD WITH CHIP IN THE SEAM OF A GARMENT

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a device for supplying and inserting yarn with a chip in the seam of a garment, providing, for the intended function, advantages and characteristics, which are They 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 means to provide the supply of chip wires, particularly wires with RFID ( Radio Frequency Identification or radio frequency identification) chip and NFC ( Near Field Communication Communication) antenna. near field) of those incorporated into clothing as a security measure against theft, which device, at the same time, allows the introduction of said thread with chip in the seam of a garment during its manufacture to through compressed air supply means.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of electrical-electronic devices and devices, specifically covering the field of those involving chip wires, as well as the scope of the industry. textile.

BACKGROUND OF THE INVENTION

The wires that are embedded with RFID chips with antennas along them are known on the market. A portion of said thread with a chip and an antenna is inserted somewhere in a garment (hem, neck, sleeve ...), replacing traditional RFID tags, which are visible 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 it 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 must be cut so that the portion of the thread to be incorporated into the garment contains a chip and the corresponding antenna.

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

The thread can also be delivered in the form of a spool. In this case the seamstress must cut the thread correctly, so that it contains only a chip and an antenna, and place it on the piece of clothing.

The problem is that the thread is difficult to place, since it needs to be placed straight or practically straight for the antenna to fulfill its function, since when the thread is bent the chip does not work. In addition, the supply of the thread to the seamstress is difficult, as it is a thread that easily folded and difficult to manipulate.

To solve this problem, the applicant himself has developed a device, suitably protected in a patent application, designed to make the supply of said thread the optimal one to facilitate its collection by the seamstress and to be able to properly place it on the garment, for which essentially, it comprises a support structure; means for displacing the thread coming from a coil; guide means that set the thread straight; detector means that check the position of the RFID chip in the thread; means for checking the operation of the RFID chip; a cutting means that cuts the thread into a segment that includes a chip; means that partially eject the thread segment (4) with a functional chip to be collected; and computerized control means of all the electrical and electronic components that include said means.

Said device, however, although it satisfactorily fulfills the function for which it is intended, it presents certain aspects that can be improved. In particular, those referring to the limitation of its functionality, since it is only designed to supply the threads, cut and checked, so that the seamstress picks them up in the ideal position, but must, from there, be the one who grasps and inserts the thread in any of the seams of the garment during its manufacture, an operation that would be desirable to be able to be carried out automatically and in a controlled manner, since this type of thread is very delicate to handle and its introduction into the seam without wrinkling or misplacing it is a special skill to be able to do it quickly and correctly, which can therefore lead to a slowdown in production that affects manufacturing costs.

The objective of the present invention is, therefore, the development of a device of the aforementioned type in a more advanced version that, in addition to providing the means to supply the yarns, that is, cut with a chip, tested and correct position, also provide the means to insert these threads directly into the seam of the garment at the time of making it when making the garment and can only do it when required, since logically, it is only included in some 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, although as has been said, a similar application device for the supply of chip yarns is known, at least by the applicant, the existence of of any other device for the supply and insertion of yarn with a chip in the seam of a garment or any other invention that has the same, similar, technical, structural and constitutive characteristics as the one claimed here.

EXPLANATION OF THE INVENTION

The device for the supply and insertion of yarn with a chip in the seam of a garment that the invention proposes is configured as a remarkable novelty within its field of application, since, according to its implementation, the objectives previously indicated as suitable, being the characterizing details that make it possible and that distinguish it conveniently included in 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 clothing, normally as an alarm means, and also to insert it directly into the garment's seam during its manufacture with a sewing machine or even once it has been made, being said thread already cut to contain a chip, placed in the appropriate position and having been checked for correct operation or discarded if it is not suitable, said insertion of the thread taking place in the seam thanks to compressed air impulsion means.

For all this, the device is incorporated conveniently installed next to the sewing machine and includes integrated in its structure a set of electrical and electronic means that, controlled by a computer system implemented in a PLC, make this delivery possible starting from a coil where the thread is in continuous as well as its insertion 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 coil to a first area of the device where a first tensioner passes it through an impeller that helps guide the thread in front of visual detection means, preferably a contrast sensor, which Check the position of the thread and chip marks.

After this, a second tensioner faces the thread towards a motorized roller that is protected inside an aluminum receptacle, which acts as a means to move the thread since it pushes it towards the cutting means located next, which, consisting of a shear, they cut the thread into a segment containing a chip.

Next, the device incorporates the means of detecting the correct operation of the chip, consisting of the existence of a RFid chip detection and checking sensor, in front of which the wire passes inserted into a tube, which we will call the conductor. To said conductive tube, compressed air is introduced, which moves the wire through the conductive tube to the selector. During the path of the wire, the selector allows the compressed air to exit through another duct. When the thread reaches the selector, the selector, if the thread chip works correctly, allows it to pass into 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 into the guide, and allowing it to exit the device through a duct for this purpose.

It should be noted that, preferably, the tube (8) acts as an outlet for compressed air from the conductive tube (7) so that it comes out during the first phase of air injection, since it is interesting that the air that exists prior to the wire (3) exit the system, since otherwise the thread would wrinkle inside said tube and would not advance. Once said air prior to the thread (3) has already exited and said tube (8) is closed.

Optionally, the detection and verification sensor of the RFID chip also serves as a recorder, to configure it with information, for example, size, model, or other, and can be modified by the merchant user or distributor of the garment using a device equipped with the means corresponding communication.

For its part, said tubular guide consists of a thin conduit, preferably metallic and preferably aluminum, which has a curved configuration and is of sufficient length to allow the introduction of the entire length of a thread with chip inside a seam in the time to perform it on a garment with the machine to which the device is attached.

For this, in addition, this guide is anchored to the machine coupled to a universal adapter, which allows it to be placed next to the needle of the machine without interfering with its normal operation.

And, advantageously, said adapter is incorporated in a tilting clamp that allows it to be easily removed from the garment's handling area when it is not necessary to introduce any chip yarn.

Likewise, preferably, the distal end of the metallic tubular guide that provides the introduction of the thread into the seam driven by compressed air, has a pointed tip that allows said thread to be inserted into previously closed seams.

In any case, it should be mentioned that the described arrangement of the different means of operation of the device may undergo variations as regards the order of position of each of them, as long as their function continues to be effective.

Lastly, it should be noted that the machine in which the device of the invention is installed, preferably, is a machine that performs overlock or overcast seams, which is known to be a type of seam that is carried out 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 inserted into said encapsulation, although this is not a limitation.

The device described for supplying and inserting yarn with a chip in the seam of a garment consists, therefore, of an innovative structure with characteristics hitherto unknown for the purpose for which it is intended, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the exclusive privilege that is requested.
