1 TARIFF 5 THREAD SUCTION MECHANISM FOR AUTOMATIC SPLITTING UNIT TECHNICAL FIELD OF THE INVENTION This invention relates to a textile ring spinning machine. Specifically, the invention concerns automatic ring spinning machines. It relates to a yarn suction device for a yarn splicing unit. More specifically, the invention relates to textile ring spinning 10 In order to perform the automatic splicing process in the machines, the broken end of the yarn must be removed (yarn It relates to a device for retrieving broken threads from the carrier. BACKGROUND OF THE INVENTION Ring spinning machines are the final, most critical machines in textile yarn production lines. These are spinning machines. These ring spinning machines produce the final form of cotton pulp on the spinning line, namely 15 It produces yarn. Yarn breaks frequently occur in ring spinning machines, and this situation affects the yarn. This is one of the main problems faced by the industry worldwide. Yarn breakage is a constant problem. The threads should be monitored and any broken threads should be immediately reattached by the workers. Thread breakage indicates damage to the thread and... This is caused by various parameters of the machine and is usually unavoidable. Long ring spinning machine. Along the lines, human labor constantly monitors for yarn breaks and walks along the ring machine 20 It reconnects broken threads by hand. This process typically involves more than 1800 spindles and approximately 75 meters of yarn. This is done for a machine body of a certain length. After the broken thread is successfully reattached, For each broken needle, the spinning process must be restarted immediately; otherwise, yarn will be wasted. To overcome the problems mentioned above, automated splicing units are being developed. The automatic insertion unit is in the form of a mobile vehicle equipped with guiding elements. (Source 25) The subject of the splicing tool is the needle positioned with the broken thread requiring splicing. Splicing The unit typically moves longitudinally along the machine body aisle. The insertion process... Before starting, the insertion tool is positioned in front of the corresponding spindle position on the ring spinning machine. Then, The broken thread end should be identified and separated from the cap (thread carrier) where it is located, lifted up, and reattached. The process must be made possible. The automatic separation of the yarn from the cap (yarn carrier) is required. 30 It is usually a difficult job. A ring spinning machine spins yarn onto a bobbin called a "cop," which is mounted on a spinning needle. It allows for winding. When a yarn breaks during the spinning process, the broken yarn is caught (yarn carrier). It becomes tangled inside. In order for the thread splicing process to be carried out, the tangled end of the thread must be cut off. It needs to be separated from the (thread carrier). To retrieve the broken thread end from the (thread carrier), 35 2 Automatic splicing units are generally equipped with suction devices. The cylindrical suction nozzle has an opening of 5. It extends outwards from the splicing unit along with its opening and is usually at the top of the cop (thread carrier). By positioning it at a predetermined distance, the yarn end is cut off from the yarn carrier. It is placed there to be sucked. Traditional ring spinning machines are configured with two rows (left and right sides of the machine), and these two The distance between the centers of the needles in a row is typically 620 mm; this distance is characteristic of modern ring spinning. Compared to traditional ring machines, it has a very narrow and compact structure. In spinning machines, the vertical axis of the spindles is the output pressure of the drawing mechanism of the ring spinning machine. It is located in the same vertical plane as the area where the fibers exit the cylinders. This arrangement is used in textile yarn production. integrating automatic splicing units into traditional ring spinning machines used in factories This constitutes a major limitation in this respect; because the fiber exit area of ​​the exit printing cylinder is 15 inches from the spindle axis. It is located on the plane. In addition, it has an automatic splicing unit for traditional ring spinning machines. After integration, the yarn take-up mechanism of the automatic splicing unit, the suction nozzle (yarn) When the suction nozzle is placed on the broken thread (on the carrier), it cannot reach the needle position, therefore both damaging both the ring spinning machine components and the automatic splicing unit by hitting them. This is the tendency. These damages, which occur in the automatic splicing unit and ring spinning machine, frequently occur around 20 years of age. This requires part replacement. During the automatic splicing process, the suction bell sucks up the broken thread while the suction bell exits the pressure roller. It hits and damages this cylinder because the suction nozzle cannot reach the spindle position to pick up the broken thread. This can lead to problems. In addition, the suction nozzle should be detached (thread carrier) before initiating the splicing process. In order to lift the lappet hook before placing it on the broken thread, the suction nozzle outer 25 Assembly of lappet tilting guide components that slide along the suction bell surface. is necessary. Capable of reliably picking up the yarn from the cap (yarn carrier), without damaging the printing cylinders and machine components. an improved yarn that does not leak and also prevents damage to the suction nozzle. There is a need to improve the suction system; this invention offers a solution to this need. 30 OBJECTIVES OF THE INVENTION These purposes involve simplifying some concepts that are explained more comprehensively in detail below.
