[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0022] See attached Figures 1 to 4 As shown, this embodiment provides a yarn winding device, which includes a first support member 10, a second support member 20, a guide module 30 and a detection module 40, wherein the yarn winding device performs an operation of winding the yarn T on a winding drum B2 for installing the yarn T on a sewing machine and using it.
[0023] The first support 10 includes a support portion 100 and a first bobbin support member 110. The first bobbin support member 110 is configured so that the bobbin B1 for yarn is detachable, and the first bobbin support member 110 is configured so that the first bobbin support member 110 can rotate around the axis of the bobbin B1 for yarn. For example, the first bobbin support member 110 can be configured to press and fasten to both ends of the bobbin B1 for yarn in the axial direction. The support portion 100 can rotatably support the first bobbin support member 110. For example, the support portion 100 can be formed with a support groove at its upper end portion, which rotatably supports the first bobbin support member 110 and both sides of the bobbin mounting shaft, which is inserted into the yarn bobbin B1.
[0024] The second support frame 20 is located in the rear area, and rotatably supports the jet bobbin B2, and the yarn T unwound and supplied from the yarn bobbin B1 located in the first support frame 10 is wound on the jet bobbin B2. The second support member 20 includes a second bobbin support member 200, a coil driver 210, and a pressing member 220. For example, the second bobbin support member 200 can be configured to press and fasten to both ends of the bobbin B2 for jetting in the axial direction, and the bobbin driver 210 can be connected to one side of the second bobbin support member 200 to rotate the second bobbin support member 200 around its axis. For example, the winding driver 210 can be configured as a motor or the like, and for example, the pressing member 220 can be connected to one of the second bobbin support members 200 to move the second bobbin support member 200 in the axial direction. Therefore, in a state where the distance between the second bobbin supporting members 200 is greater than both ends of the bobbin B2, the bobbin B2 may be disposed between the second bobbin supporting members 200, and one of the second bobbin supporting members 200 may be moved toward the bobbin B2 by the pressing member 220 to fix the bobbin B2. Then, after the yarn T is fixed to the outside of the bobbin B2 for injection, when the second bobbin supporting member 200 and the bobbin B2 for injection supported by the second bobbin supporting member 200 are rotated by the winding driver 210, the yarn T supplied from the bobbin B1 for yarn located on the first support 10 is wound around the guide module 30 for injection located in the section between the first support 10 and the second support 20 to guide the position of the yarn T supplied to the second support 20 in a direction intersecting the front-rear direction.
[0025] Refer to the attached Figure 5 As shown, the guide module 30 includes a reciprocating member 310 and a guide driver 321, the reciprocating member 310 is located in the section between the first support 10 and the second support 20, and is configured to be movable in a direction intersecting the front-back direction. As an example, a guide rod 300 is provided in the section between the first support 10 and the second support 20 in a direction intersecting the front-back direction, and the reciprocating member 310 can be movably connected to the guide rod 300 along the length direction of the guide rod 300. The reciprocating member 310 has a guide hole 311, and the yarn T passes through the guide hole 311. Therefore, when the reciprocating member 310 reciprocates in a state where the yarn T passes through the guide hole 311, the position where the yarn T is supplied to the second support 20 changes.
[0026] The guide driver 321 is connected to the reciprocating member 310 to provide power for the movement of the reciprocating member 310. For example, the guide driver 321 may be connected to the rotating link 322 to rotate the rotating link 322 around a rotation axis set in a direction intersecting the movement direction of the reciprocating member 310. In addition, one end of the connecting link 323 is rotatably connected to a position of the rotating link 322 eccentric to the rotation axis of the rotating link 322, and the other end of the connecting link 323 is rotatably connected to the reciprocating member 310. Therefore, when the rotating link 322 is rotated by the guide driver 321, the reciprocating member 310 reciprocates, for example, the sensing module 40 is located in a section between the first support 10 and the second support 20 to sense the length of the yarn T supplied in the direction of the second support 20.
[0027] The sensing module 40 includes a guide roller 410, a sensor 415, and an auxiliary guide roller 420. A groove for accommodating the yarn T may be formed on the outer peripheral surface of the guide roller 410. The yarn T supplied from the first support 10 to the second support 20 moves while contacting the outer peripheral surface of the guide roller 410, thereby rotating the guide roller 410. The sensor 415 is connected to the guide roller 410 to sense the number of revolutions of the guide roller 410. Therefore, the controller (not shown) can calculate the length of the yarn T supplied to the second support 20 by the number of revolutions of the guide roller 410 and the length of the outer peripheral surface of the guide roller 410. Therefore, when the length of the yarn T supplied in the direction of the second support 20 reaches a predetermined value, the controller can stop the winding driver 210 so that the winding of the yarn T on the bobbin B2 for injection ends, so that the yarn T is wound on the bobbin B2 for injection by a predetermined length when the auxiliary guide roller 420 is located in front of the guide roller 410 and adjacent to the guide roller 410. The auxiliary guide roller 420 is rotatably arranged with respect to an axis arranged in the left-right direction. The length of the outer peripheral surface of the auxiliary guide roller 420 may be less than the length of the outer peripheral surface of the guide roller 410, so that the upper end and the lower end of the auxiliary guide roller 420 may be located in the portion between the upper end and the lower end of the guide roller 410.
[0028] The direction switching member 425 is located between the auxiliary guide roller 420 and the guide roller 410. The lower end of the direction switching member 425 is located below the lower end of the auxiliary guide roller 420, and the upper end of the direction switching member 425 is located at a position facing the upper end of the auxiliary guide roller 420. A first switching hole 426 and a second switching hole 427 are sequentially formed upward at the lower end of the direction switching member 425, and a third switching hole 428 is formed at the upper end of the direction switching member 425. The yarn T supplied from the front sequentially passes through the first switching hole 426 and the second switching hole 427 and contacts the outer surface of the auxiliary guide roller 420, and then passes through the third switching hole 428 and contacts the outer surface of the guide roller 410. Therefore, the yarn T thicker than the ordinary sewing thread can be supplied while maintaining contact with the outer surface of the guide roller 410 without sagging. The alignment member 430 formed with the alignment hole 431 can be located at the rear of the guide roller 410. The alignment hole 431 may be formed at a height corresponding to the guide hole 311. Therefore, the yarn T passing through the guide roller 410 may be supplied through the alignment hole 431 to be inserted into the guide hole 311, so that the yarn T supplied to the guide module 30 is in a horizontal state close to the yarn winding device 1 according to an embodiment of the present invention, and the yarn T may be effectively and automatically ejected onto the bobbin B2 for ejection.
[0029] Furthermore, according to the yarn winding device of the embodiment of the present invention, the yarn T is uniformly wound around the outer circumference of the bobbin B2 for injection, and the yarn T can be automatically wound to a predetermined length.
[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
