The housing (11) in fig. 2, is an overall view of the housing (11) and functions as a structure on which all devices and groups are located. The yarn feeding group (14) realizes the transmission of the yarn in the yarn winding machine (10). The winding group (20) is wound by the yarn taken from the feeding group (14) without a pulley in the center. The purpose of the traverse group (30) is to form a pattern during yarn winding and prevent the yarn from being continuously wound to the same area and winding the yarn with a desired pulley width. The winding actuator group (40) starts the first winding and moves the yarn ends away from the centre by catching the ends of the yarn exiting from the yarn feeding group (14). The winding control centre (50) is used for measuring and controlling the winding diameter of the wound yarn and also as a bearing for the elements of the winding starter group (40). The yarn transfer group (60) transfers the wound yarn to the press unit (80). The press unit (80) is a unit for shaping the wound yarn. The pressure unit (80) is driven by sequentially positioned piston groups (70). The automation and control group (12) comprises a main screen, in which all the adjustment parameters and settings required for the winding and compression process are entered. An automation and control group (12) (an overall view of which is given in fig. 3) is associated with the electro-pneumatic group (13).

With reference to the detailed view given in fig. 5, the winding group (20) comprises: a winding group body (21) including a winding group (20) device; a group movement shaft (22) on which the winding group main body (21) moves in a linear movement; a winding shaft (23) on which the yarn taken from the yarn feeding group (14) is wound; a primary forming side (24) arranged in the continuation of the winding shaft (23) forming a yarn winding configuration; and a rotating motor (25) that rotates the winding shaft (23) and the primary forming side (24). The movement of the rotary motor (25) is transmitted to the primary forming side (24) through a right idle wheel rotation group (241). The winding group body (21) includes a body support (211) that restricts linear movement of the winding group (20); and a sleeve (212) disposed on the group movement axis (22) to determine a limit of linear movement between the body support (211) and the winding group body (21). The main body support (211) is mounted on the machine body (11) and at the same time serves as a bearing for the rotating electrical machine (25). The group movement axis (22) includes: shaft covers (221) provided at both ends of the outside of the winding body group (21) for preventing air leakage from the piston through which the group moving shaft (22) passes; and a shaft centering piston (222) disposed in the middle of the group moving shaft (22) to push the winding group body (21) toward the body support (211). The winding shaft (23) further includes a shaft holding clip (231) that integrates the winding shaft (23) and the shaft of the rotating electrical machine (25).

The motion transmission shaft (33) includes: a base member (332) and base covers (331) provided on both sides of the base member (332). The traverse motor bearing (34) includes: a motor moving shaft (341) that associates the traverse group motor (32) with the traverse group main body (31) and linearly guides them; a motor motion piston pin (342) providing linear motion to the traverse group motor (32); a piston seal (343); piston covers (344) disposed at both ends of the motor motion piston pin (342); and a linear motion restriction member (345) for restricting the linear motion of the traverse group motor (32).

With reference to the detailed view given in fig. 7, the winding actuator group (40) comprises: a winding starter group main body (41) with the quality as a carrier main body, a winding starting piston group (42), a left idle wheel group main body (43) returning when the winding yarn is discharged, a hook group main body (44), scissors (45) which cut the yarn end after the winding is finished and are driven by a standard piston, a fine clearance adjusting wheel (46) which limits the movement of the winding group (20), and a secondary forming side surface (47) which can enable the winding to be formed. The winding actuator assembly body (41) includes a piston assembly bearing shaft (411) that manually provides linear movement of the winding actuator piston assembly (42). The left idle gear group main body (43) includes: a left idler piston shaft (431), a piston front cover (432), and a piston rear cover (433) that move the left idler set body (43) and act as a bearing for the hook set body (44) to provide tightness of the left idler piston shaft (431). The hook set body (44) includes: the method includes starting a hook group piston shaft (441), a hook group front cover (442), and a hook group rear cover (443) that move a hook group main body (44) by winding a piston movement in a piston group (42) to provide tightness of the hook group main body (44) and the hook group piston shaft (441), receiving a driven hook gudgeon pin (444) from the hook group gudgeon pin (441), providing tightness of the hook gudgeon pin (444), a hook fixation clamp main body (446), a hook fixation clamp (447), a hook tube (448), and a hook (449). The hook tube (448) is driven by a wrist pin, and a hook (449) is included in the hook tube (448). The hook tube (448) is a member movable back and forth, and the hook (449) opens and closes in the hook tube (448). The opening and closing is achieved as follows: the hook is closed when the hook tube (448) covers the end of the hook (449), and the hook is opened when the hook tube (448) is pulled backward. The hook (449) catches the yarn and the hook (449) secures it by a hook retaining clip (447). A hook retaining clip (447) is located in the hook retaining clip body (446). The scissors (45) comprise: a scissors fixing body (451) connecting the scissors (45) with the winding actuator group body (41), and a scissors piston base portion (452) on which the scissors (45) are seated. The fine gap adjustment wheel (46) includes a wheel main body (461) on which the wheel is mounted, the wheel main body (461) protecting the wheel from external influences.

With reference to fig. 8, which gives a detailed view, the winding control centre (50) comprises: a winding central body (51) acting as a bearing for the elements of the winding actuator group (40) and carrying on itself the relative winding control central element (50); an intermediate motion transfer wheel (52) that transfers motion from the primary forming side (24) to the secondary forming side (47); a yarn traverse gear box (53) having needles, from which the yarn is moved to the winding shaft (23) to be wound; a winding control piston part (54); a diameter density control wheel (55) able to contact the yarn from below during winding of the yarn; and an encoder fixing body (56) in which the encoder is located. The intermediate motion transfer wheel (52) comprises: a motion transmission piston (521), a piston fixing member (522) connected to the motion transmission piston (521), a wheel handle (523) to which an intermediate motion transmission wheel (52) is attached, and a wheel fixing member (524) connecting the wheel handle (523) to a winding center body (51). The motion transfer piston (521) presses the wheel downward. Nevertheless, when the wound yarn diameter reaches a predetermined winding diameter, the intermediate motion transfer wheel (52) can be raised by deactivating the motion transfer piston (521). The yarn traverse gearbox (53) is associated with a motion transmission group (531), the motion transmission group (531) transmitting the motion received from the motion transmission shaft (33) to the yarn traverse gearbox (53). The winding control piston portion (54) includes: a piston portion piston cover (541), a piston portion piston seal (542), a gear (543), a gear shaft (544), and a gear shaft bearing (545). The diameter density control wheel (55) includes: a wheel bearing (551), a handle (552) associated with the diameter density control wheel (55) and moved by the movement of the diameter density control wheel (55), a drive shaft (553) transmitting the movement received from the control wheel (55) to the gear (543), and a drive shaft cover (554). The encoder fixing body (56) includes: an encoder fixed body cover (561) and an encoder circular gear (562), the encoder circular gear (562) transmitting the linear motion it receives from the drive shaft (553) to the encoder.

The winding control piston portion (54) substantially constitutes a part of the winding center body (51). During winding, the diameter density control wheel (55) moves upward and contacts below the yarn that begins to be wound on the winding shaft (23). As the winding diameter increases, the diameter density control wheel (55) moves downward with the applied air pressure, and at this stage, the handle (553) rotates. At the same time, the gear (543) is subjected to opposite strengths by means of the gear shaft (544) in order to easily idle the control wheel (55) without the air pressure in the winding control piston part (54). Therefore, the diameter density control wheel (55) which generates pressure under the winding yarn is lowered by applying a predetermined pressure when the winding diameter is increased. Therefore, the winding density of the yarn can be adjusted.

With reference to fig. 9, which gives a detailed view, the yarn transfer group (60) comprises: a group driving piston (61), a mounting part (62) to which elements of the yarn transferring group (60) are connected, a guide rail (63) which is connected in the machine body (11) and on which the yarn transferring group (60) moves, an L bearing (64), and a reel handle (65) which holds a reel which has completed winding. The group drive piston (61) provides for all yarn transfer group (60) elements except the guide rail (63) to provide for a back and forth movement relative to the press unit (80). A bearing moving gear (641), a gear supporting shaft (642) and a bearing moving motor (643) are provided on the L bearing (64). The reel handle (65) comprises: a handle fixing part 651 arranged in the L bearing 64, a handle piston 652 for opening and closing the reel handle 65, and a handle motor 653. The handle fixing part (651) is moved upward by the handle motor (653) while being rotated by a bearing movement motor (643) after the reel is fixed.

The piston group (70) includes a compression member (71) provided at an end thereof. The press unit (80) comprises: a press body (81), a discharge member (82) pushing the reel to the outside, a discharge piston (83) pushing said press body (81) to the outside, and a resistor (84) providing the required heat for heating the reel. The compression member (71) compresses the spool between the discharge member (82) and itself by the force it obtains from the piston assembly (70). By the effect of the compression and heat obtained in this way, the finished wound yarn is shaped.

In order to realize the winding process of the coreless winding shaft, firstly, the lubricated yarn wound on the large bobbin is wound on the winding shaft (23). The process manually includes the yarn on the feeding group (14) of the system by positioning the large bobbin on the body (11), by traversing the yarn through the yarn traversing gear box (55). After manual feeding, all the operating parameters related to the yarn winding machine (10) are entered into the automation and control group (12), and the system is then awaited for entering the production program. After the machine operation, the yarn manually wound on the winding shaft (23) starts to be wound on the winding group (20) through the winding shaft (23). With the start of the winding process, the diameter density control wheel (55) starts to compress the wound yarn from below. The diameter density control wheel (55) starts moving downward with an increase in the winding diameter. When the winding process reaches the value of the parameters input to the machine, winding is complete, the winding-starting piston group (42) returns and returns the left idle group body (43) and the secondary forming side (47). Then, the reel handle (65) is moved upward to hold the reel. Then, the winding group main body (21) is moved backward, and the winding shaft (23) is moved away from the center of the winding reel. By pulling down the reel held by the reel handle (65), the yarn end is cut by scissors (45) within the winding actuator group (40). The free-end winding shaft is transmitted to the press unit (80) by the movement of the yarn transmission group (60) on the guide rail (63). During this transfer, the cut free end of the yarn is held by the hook (449) and inserted into the hook tube (448). Then, the winding group main body (21) is moved forward, and the winding shaft (23) is again brought to the winding position. At the same time, the diameter density control wheel (55) is moved to the winding position again by the winding control piston group (54), and the winding is continued again for the same yarn wound on the large bobbin. When the piston group (70) pushes the compression member (71) by moving in its advancing direction, the reel of the press unit (80) is formed in the press unit (80). At the end of the predetermined time, the compression reel and the heat staying within the press unit (80) for the predetermined time are discharged from the press unit (80) through the discharge means (82), and the winding process is terminated.
