Description

DESCRIPTION

METHOD AND DEVICE FOR THE MANUFACTURE OF WELDED YARN Technical Field

The present invention is related to the yarn manufacture method in the textile industry. The said invention consists of a method and a device providing two yarn cords having two different color and/or qualities to be transformed into welded yarn by being combined in the manufacture of all kinds of woven and knitting yarn manufacture.

State of the Art

Today, yarns with several colors and qualities are used in order to obtain different appearances in woven fabrics and knitting. These yarns provide the forming of visually different patterns in the structure of the woven fabrics or knitting. The yarns can be manufactured in both one color and several colors in order to provide this visuality.

During the standard yam manufacture, the process steps such as batch, carding, draw 1 , draw 2 and cord forming are performed first. The yam cords formed are fined and bended in the ring yarn machines, and then they become usable yarns. Thanks to this yarn manufacture method, unicolor woven and knitting yarns are obtained. When bicolored fancy yarns are desired to be formed, each one of two colored yarns is firstly formed via standard yarn manufacture method. Then, these yarns are combined and bended. Thus, bicolored fancy yarns are obtained. This method comprises costly and long-term process steps. Moreover, there may occur unwinding between the yarns during use, because two different yarns are combined in the bending stage.

In the present embodiments, bicolored fancy yarn manufacture is performed by dividing the aprons into two in the spinning mechanism where the yarn cord is fined. In this method, main yarn cord and the other colored yarn cord are combined by grasping and loosing, thanks to the magnetic grasper on the middle roller. Thus, a single yarn is obtained from a yarn cord with two different colors. However, it is a costly method. It is worked with gas-brake mentality, the other colored yarn cord to be fed onto the main yarn cord is passed through a separate sleeve on the rear roller. High level of efficiency cannot be ensured in the yarn manufacture.

Electromechanical devices are added to the yarn spinning mechanism in order to enable the rotation of the output rollers in a controlled manner and to determine the operation period. Thus, another yarn cord is fed onto the main yarn cord in the desired amount. However, it is a costly method.

The known improvements in the state of the art relating to the subject are given below.

The patent with the application number 2010/03573 is related to a spinning unit for the manufacture of welded yarn. The invention comprises a spinning unit providing welded yarn manufacture by combining cords with two or more colors and qualities to yarn. In order for the cords to be welded onto the yarns in desired amounts, there are pores on the sleeve, which are formed in desired lengths, widths and depths throughout the sleeve. In this method, the amount of the cords with other colors and qualities fed on the yarn is limited to the diameter of the sleeve. Main yarn and welded parts are fixed. And, the distance between the welded parts is always the same and it cannot be changed arbitrarily.

The utility model with the application number 2007/00829 is related to an apparatus added to the yarn machines with ring system. The invention consists of a mechanism added to the yarn machines with ring device in order to discharge different material between the yarns during the manufacture of the yarn, and directs the intermediate material. This mechanism comprises an apparatus grasping body carrying and positioning the rollers directing the intermediate material attached on the pistol connected the machine, and a position adjuster attached on this grasping body. Moreover, roller crankpins, adjustment knob, spring, bolt and stay bolts are attached on the position adjuster. The mechanism according to the invention provides only the discharge and direction of another material in the yarn machine during the manufacture. It is not enabled to adjust the amount and thickness of the discharged material.

The above mentioned methods and mechanisms are costly and fast yarn manufacture cannot be provided. Moreover, it requires a very long time to make these mechanisms ready for the manufacture of standard single-colored yarn from bicolored yarn and bicolored yarn from standard yarn. As a result, a novel manufacture method and device are required in order to eliminate the above mentioned disadvantages and provide solutions for the present devices with regards to the welded yarn manufacture.

Detailed Description of the Invention

In this detailed description, the welded yarn manufacture method and device according to the invention are described in order for the subject to be better understood, without any limiting effect.

In the manufacture of the single-color and/or quality yarns, the cords (5) delivered from the cord machine are fined by spinning via standard spinning mechanism (1 ) in the yarn machines. After this fining, the cords (5) are bended and become usable yarns. In Figure 2, the schematic view of the standard spinning mechanism (1 ) used in the state of the art is given/ Standard spinning mechanism (1) is composed of successively arranged first roller (40), second roller (30), third roller (20) and sleeves (21 ,31 ,41 ) positioned on these rollers (20,30,40). In addition, the surfaces of the second roller (30) through which the yarn cord (5) passes, and the sleeves (31 ) are covered with aprons (50 and 60). When the welded yarn (7) is desired to be manufactured, weld yarn roller (10) and weld yarn roller sleeve ( 1 ) are added to the standard spinning mechanism (1). Weld yarn roller (10) is connected to a drive member (12) that is operated via a control unit (13) through a control panel (14). In addition, a direction apparatus (15) is positioned on the weld yarn roller (10). Thanks to this device (2) obtained with the parts (10, 1 1 ,12,13,14,15) added to the standard spinning mechanism (1) and providing the manufacture of weld yarn (7), weld yarn cord (6) is fed on the main yarn cord (5). In addition, these cords (5,6) are directed so as to move all together on the device (2). As the weld yarn device (2) consists of a basic structuring, it can easily be transformed into standard spinning mechanism (1 ) in a very short time. It takes approximately 1-2 hours to dismount the parts (10,1 1 ,12,13,14,15) from the mechanism (1), that are added to the mechanism (1 ) in order to obtain this device (2). Thus, the yarn machines are enabled to manufacture welded yarn (7) from the standard single color and/or quality or vice versa in a very short time.

In Figure 1 , the schematic view of the welded yarn (7) manufacture device (2) according to the invention is given. As seen in the figure, this mechanism comprises 4 spinning rollers (10, 20, 30, 40) arranged successively and sleeves (1 1 , 21 , 31 , 41 ) positioned on these rollers (10, 20, 30, 40). In addition, there is a direction apparatus (15) positioned on the weld yarn roller (10). Welded yarn (7) is a type of yarn obtained with the combination of main yarn cord (5) and weld yarn cord (6). Main yarn cord (5) and weld yarn cord (6) consist of fibers that are fined to some extent in order to obtain yarn. Main yarn cord (5) and weld yarn cord (6) are chosen in different colors for welded yarn (7) to gain importance visually. Some parts on the welded yarn (7) appear as yarn made of main yarn (5) and weld yarn cord (6), while some other parts appear as yarn made of only main yarn cord (5). The amount and the thickness of the weld yarn cord (6) fed on the main yarn cord (5) can be arranged in desired manners.

The main yarn (5) and weld yam (6) cord balls received from the cord machine during the yarn manufacture, are fixed on the cord hangers in the creels positioned on the weld yarns device (2). Main yarn cord (5) placing into the device (2) through the cord bobbins hanged on the creels firstly passes between the third roller (20) and third roller sleeve (21 ). The third roller (20) consist of spinning roller providing the motion of the main cord yarn (5) onto the next weld yarn roller (10). There are pores on the third roller (20), where the main yarn cord (5) passes through, in order to prevent slipping. The third roller sleeve (21 ) is in the shape of a pressing roller coated with rubber, which provides the spinning of the cord (5) in a controlled manner. The other rollers (10, 30, 40) and the sleeves (1 1 , 31 , 41 ) on the weld yarn device (2) have the same structure as the third roller (20) and its sleeve (21 ). There are weld yarn roller (10) and weld yarn roller sleeve (1 1 ) positioned on this roller (10), between third roller (20) and second roller (30). Main yarn cord (6) placing into the device (2) through the cord bobbins hanged on the creels firstly passes between the weld yarn roller (10) and third roller sleeve (1 1). The motion of the weld yarn roller (10) is provided by a separate drive member (12) apart from the other rollers (20, 30, 40) on the spinning mechanism. Step or servo motor is used as drive member (12). The weld yarn roller (10) receives its motion from step or servo motor (12), and thus the motion of the weld yarn roller sleeve (1 1 ) is provided via this roller (10). Step or servo motor (12) is connected with the control unit (13) and control panel (14). The control of the step motor (12) is performed through the control panel (14), in which PLC control device is used. Servo driver in the control unit (13) is enabled via control panel (14), and thus the motor (12) is operated. In Figure 7, the detailed schematic view showing the connection of weld yarn roller (10) to the drive member (12) is given.

While weld yarn device (2) is in use, the main yarn cord (5) is fed to the system through the third roller (20), and weld yarn cord (6) is fed to the system through weld yarn roller (10). The main yarn cord (5) reaches onto the weld yarn roller (10) in a smooth manner through the third roller (20). The length (b) of the surface of the weld yarn roller sleeve ( ) which is in contact with the roller (10) is shorter than the length

(a) of the other sleeves (21 ,31 ,41) (a > b). By means of the fact that the weld yarn roller sleeve (1 1) is half-used (a/2) unlike the other sleeves (21 , 31 , 41 ); the regular flow of the main yarn cord (5) on the roller (10) is not hampered. Weld yarn roller sleeve (1 1) provides only the controlled spinning of the weld yarn cord (6). The length

(b) of the surface of the weld yarn roller sleeve (1 1 ) which is in contact with the roller (10) is required not to hamper the regular flow of the main yarn cord (5) on the roller (10). In Figure 9, the schematic view of the sleeves (1 1 ,21 ,31 ,41 ) used in the welded yarn (7) manufacture according to the invention is given. A direction apparatus (15) is positioned on the weld yarn roller (10). Direction apparatus (15) increases the working performance of the welded yarn (7) manufacture mechanism (2) and provides the direction of the yarn cords (5,6) in a way to be together. The views of the direction apparatus (15) from different angles are given in Figures 3, 4, 5 and 6. As seen in the figures, the direction apparatus ( 5) consists of a configuration comprising support member (16), connection member (17), cord direction handle (18), cord passage space (18.1 ) and cord direction hook (19). The support member (16) is in the shape of a quadrangle tall profile, and serves as a stand fixing the apparatus (15) where it is positioned. This stand (16) is positioned between the third roller (20) and weld yarn roller (10). There are two cord direction hooks (19), which are connected to the support member (16) in such a way to fall behind the weld yarn roller sleeve (1 1 ). Thanks to these hooks (19), the passage of the main yarn cord (5) by being directed through the weld yarn roller (10) so as not to be affected from the sleeve (1 1) is provided. There are 2 cord direction handles (18) positioned on the front part of the apparatus (15) in a reciprocal manner with the hooks (19). The direction handle (18) consists of a configuration in U form having an extension on the bottom part. The configuration in U form provides a space (18.1) for the passage of the cords (5,6). The cords (5,6) gathered on the weld yarn roller (10) thanks to this cord passage space (18.1 ) are enabled to pass to the next roller (30) in the same direction. The connection of the direction handles (18) with the support member (16) is provided with the connection members (17). The connection members (17) appear as a half-ring that provides the positioning of the apparatus (15) on the roller (10) without contacting with the roller (10) surface. This apparatus (15) facilitates the feeding of the weld yarn cord (6) on the main yarn cord (5) properly and the gathering of these cords (5,6) together. In addition, the cords (5,6) are enabled to exit from the spinning mechanism without directing in different angles. The apparatus (15) can be mounted and dismounted on the roller (10) thanks to its form.

;

Following the weld yarn roller (10), main yarn (5) and weld yarn cord (6) pass between the second roller (30) and second roller sleeve (31 ). The surfaces of the rollers (30) through which the yarn cords (5,6) pass, and the sleeves (31 ) are covered with aprons (50 and 60). Therefore, the yarn cords (5,6) are not in contact with this roller (30) and sleeve (31). The structures named lower and upper aprons (60 and 50) are made of synthetic rubber or leather. They act as a protector during the transfer of the fiber fined by spinning to the pre-spinning roller (40) without being damaged or dispersed. The fiber plurality (5, 6) passing between the first roller (40) and sleeve (41) is bended and becomes usable welded yarn (7).

In the device (2) providing the manufacture of the welded yarn (7), crusher spinning is applied between the weld yarn roller (10) and the second roller (30), and main spinning is applied between the second roller (30) and first roller to the yarn cords (5,6) . Thus, each of the yarn cords (5,6) used is processed in the same manner. The speed, working and stopping period of the drive member (12) define the characteristics of the welded yarn (7) according to the invention. The speed of the drive member (12), the operation of which is directed through the control panel (14), defines the thickness of the weld cord (6) fed on the main yarn cord (5). The working period defines the length of the weld cord (6) fed, while the stopping period defines the length of the main yarn cord (5). Therefore, the weld yarn cord (6) is fed on the main yarn cord (5) in desired distances, thickness and length. Thanks to the different welded yarns (7) obtained, several kinds of fancy patterns are created in textile products. In addition, welded yarn (7) manufacture 95% faster than the conventional manufacture is performed thanks to the device (2) providing the welded yarn (7) manufacture.

Apart from the above mentioned points, an alternative device (2) providing the welded yarn (7) manufacture can be created via connection of a separate drive member (12) with the third roller (20) in the standard spinning mechanism (1 ). In this device (2), the third roller sleeve (21 ) having a surface length .(b). that does not hamper the regular flow of the main yarn cord (5) on the roller (20) is used. In Figure 8, the schematic view of an alternative embodiment of the welded yarn (7) manufacture device (2) according to the invention is given. When welded yarn (7) is desired to be manufactured, a drive member (12) which is operated via control unit (13) through a control panel (14), is connected to the third roller (20) on the standard spinning mechanism (1). Thus, the motion of the third roller (20) is provided by a separate drive member (12) apart from the other rollers (30, 40) on the spinning mechanism (1). Step or servo motor is used as drive member (12). The third roller (20) receives its motion from step or servo motor (12), and thus the motion of the third roller sleeve (21 ) is provided via this roller (20). During the manufacture of the welded yarn (7), the main yarn cord (5) is fed to the device (2) through the third roller (20), and weld yarn cord (6) is fed to the device between the third roller (20) and third roller sleeve (21). Again, similarly, the speed, working and stopping period of the drive member (12) define the characteristics of the welded yarn (7) according to the invention. By means of the fact that the third roller sleeve (21 ) is half-used (a/2) unlike the other sleeves (31 , 41 ); the regular flow of the main yarn cord (5) on the roller (20) is not hampered. The third roller sleeve (21) provides only the controlled spinning of the weld yarn cord (6). Following the third roller (20), main yarn (5) and weld yarn cord (6) pass between the second roller (30) and second roller sleeve (31 ), and then pass between the first roller (40) and its sleeve (41 ), respectively. The fiber plurality (5, 6) passing between the first roller (40) and its sleeve (41) is bended and becomes usable welded yarn (7).

In order to render the above mentioned alternative device (2) embodiment providing the welded yarn (7) manufacture so as to perform the manufacture of standard single-color and/or quality yarn, it is enough to replace the half-used (a/2) third roller sleeve (21) with the fully (a) used third roller sleeve (21) and to omit the drive member (12) connected with the third roller (20). Therefore, the yarn machines are enabled to manufacture welded yarn (7) from the standard single color and/or quality or vice versa in a very short time.
