[001] The present invention relates to a bobbin winder machine used in sewing and textile industries for winding thread onto bobbins. Specifically, the invention pertains to a cradle position adjusting assembly for a bobbin winder machine.

BACKGROUND

[002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

[003] Bobbin winder machines have long been utilized to wind thread onto bobbins, providing a convenient source of readily available thread for various textile applications. Previous designs have incorporated mechanisms to control tension, guide the thread, and ensure even winding. However, the difficulties in adjusting the cradle during the threading process have remained a significant challenge.

[004] Adjusting the cradle, which holds the bobbin during the winding process, plays a crucial role in achieving precise alignment and tension control. The cradle must be positioned correctly to ensure the thread is wound evenly and tightly onto the bobbin. However, existing bobbin winder machines often feature complex or cumbersome cradle adjustment mechanisms that are difficult to operate accurately and efficiently.
[005] The current methods of adjusting the cradle on existing bobbin winder machines can be cumbersome and require significant operator effort. Some machines rely on intricate manual adjustments, which can be prone to errors due to the complexity of the mechanisms involved. Others may employ mechanical controls that lack fine-tuning capabilities, making it challenging to achieve precise cradle positioning.

[006] The difficulties in adjusting the cradle not only impede the accuracy of the threading process but can also result in uneven tension, thread breakage, and difficulties in properly inserting the bobbin into subsequent textile machinery. Furthermore, the time-consuming and labor-intensive nature of adjusting the cradle hampers operational efficiency and increases production costs due to wasted time and materials resulting from inaccurate or defective thread winding.

[007] Therefore, there is an utmost need for an assembly for adjusting cradle accurately in the bobbin winder machine, and thus formed genesis for this invention.

DETAILED DESCRIPTION

[0017] Before the present apparatus and its components are described, it is to be understood that this disclosure is not limited to the particular apparatus and its arrangement as described, as there can be multiple possible embodiments which are not expressly illustrated in the present disclosure. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only and is not intended to limit the scope of the present application. This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in detecting or limiting the scope of the claimed subject matter.

[0018] As explained earlier, the state-of-the-art bobbin winder machine may experience difficulties in adjusting the cradle, which may not only impede the accuracy of the threading process but can also result in uneven tension, thread breakage, and difficulties in properly inserting the bobbin into subsequent textile machinery. Furthermore, the time-consuming and labor-intensive nature of adjusting the cradle hampers operational efficiency and increases production costs due to wasted time and materials resulting from inaccurate or defective thread winding.
[0019] To this end, a position adjusting assembly for a bobbin winding machine is disclosed, as an embodiment of the present disclosure. Now, referring to FIG.1, which illustrates a side view 100 of a bobbin winding device 102. The bobbin winding device 102 may include an end wall 110, through which at least one cradle shaft 108 may be supported. In an embodiment, the at least one cradle shaft may be supported on the cradle wall 114. In another embodiment, the cradle wall 114 may be connected to a linear actuator 112, such as a rack gear. The linear actuator 112 may be connected, or in mesh with a radial array of teeth 106a mounted on a transmission shaft 116. The transmission rod 116 may be connected to a transmission box, including a gearbox 104. In an embodiment, the gearbox 104 may be actuated to rotate the transmission rod 116, thereby rotating the radial array of teeth 106a. Rotation of the radial array of teeth 106a may acuate the linear actuator 112, such that the cradle wall may be advance or retracted along a horizontal axis. This is explained in detail with conjunction to FIGs. 2-5.

[0020] In an embodiment, the transmission rod 116 may include a proximal end and a distal end. The proximal end of the transmission rod 116 may be connected to the gear box 104, and the distal end may be connected to the radial array of teeth 106a. In an embodiment, the transmission rod 116 may pass through the gearbox 104 as a singular structure, thereby defining two distal ends engaged with two radial array of teeth 106a and 106b, with the two radial array of teeth 106a and 106b engaged with linear actuators 112a and 112b respectively.

[0021] Now, referring to FIG.2, illustrating a perspective view 200, FIG.3 illustrating a side sectional view 300, and FIG.4 illustrating a front sectional view 400 of the gearbox 104 as an embodiment of the present disclosure. In an embodiment, the gearbox 104 may include a casing 202, a rotary adjuster 204, and an output shaft 206.
[0022] In an embodiment, now referring to FIGs.3 and 4, the rotary adjuster 204 may be connected to a driving gear assembly 302. The driving gear assembly 302 may be further connected to an intermediate gear assembly 306. Further, the intermediate gear assembly 306 may be further connected to the driven gear assembly 402. The driven gear assembly 402 (refer to FIG.4) may be connected to the output shaft 208. In an embodiment, each of the gear assemblies may include a worm shaft and a worm gear, or a spur gear and a shaft, or a helical gear or a shaft, i.e., a shaft passing through a gear such that the gear and shaft may be rotated together in unison. In an embodiment, the diameter of the shaft may range between 28-32 mm, and the number on teeth on each gear may range between 30-34.

[0023] In an embodiment, the position adjusting assembly may operate between an extended state and a retracted state, when the driving gear assembly 302 may be actuated by the rotary adjuster 204. In the extended state, the rotary adjuster 204, when rotated in a counterclockwise direction, may actuate the driving gear assembly 302 in the same counterclockwise direction. Further, when the driving gear assembly 302 may be rotated in a counterclockwise direction, the connected gear assembly, or the intermediate gear assembly 302 may be rotated in clockwise direction. Rotation of the intermediate gear assembly 302 in clockwise direction may rotate the driven gear assembly 402 in counterclockwise direction. Since the driven gear assembly 402 may be connected to the output shaft 204, the output shaft 206 and the transmission rod 112 may rotate in counterclockwise direction.
[0024] In the retracted state, the driving gear assembly 302 may be actuated by the rotary adjuster 204. The rotary adjuster 204, when rotated in a clockwise direction, may acuate the driving gear assembly 302 in the same clockwise direction. Further, when the driving gear assembly 302 may be rotated in a clockwise direction, the connected gear assembly, or the intermediate gear assembly 302 may be rotated in counterclockwise direction. Rotation of the intermediate gear assembly 302 in counterclockwise direction may rotate the driven gear assembly 402 in clockwise direction. Since the driven gear assembly 402 may be connected to the output shaft 204, the output shaft 206 and the transmission rod 112 may rotate in clockwise direction.

[0025] Now, referring to FIG.5, which illustrates a top view 500 of an assembly of radial array of teeth 106a, 106b and the linear actuator 112a, 112b. When the transmission rod 116 may be rotated in the clockwise direction, the radial array of teeth 106a, 106b may also rotate in clockwise direction, thereby advancing, or moving the linear actuator 112a, 112b to the right along a horizontal axis, to advance or move the cradle wall 110 to the right along the horizontal axis. Similarly, When the transmission rod 116 may be rotated in the counterclockwise direction, the radial array of teeth 106a, 106b may also rotate in counterclockwise direction, thereby advancing, or moving the linear actuator 112a, 112b to the left along a horizontal axis, to retract or move the cradle wall 110 to the left along the horizontal axis.

[0026] Now, referring to FIG.6, which illustrates a front view 600 of the bobbin thread winding machine, as an embodiment of the present disclosure. The bobbin thread winding machine may include at least one cradles 602a, 602b, and 602c (hereinafter referred to as cradles 602) mounted on the cradle shaft 606, which may include and accommodate bobbins 604a, 6004b and 604c (hereinafter referred to as bobbins 604) respectively. Further, the cradle shaft 606 may be connected to the cradle wall 110. In an embodiment when the cradle wall 110 may be advanced along the horizontal axis, the cradle shaft 606 along with the cradles 602 may also advance along the horizontal axis, thereby adjusting the bobbin. Oppositely, when the cradle wall 110 may be retracted along the horizontal axis, the cradle shaft 606 along with the cradles 602 may also retracted along the horizontal axis, thereby adjusting the bobbins 604. The bobbins 604 may be adjusted with an accuracy up to 2mm depending on the rotation of the rotary adjuster 204 of the gearbox 104, thereby providing a highly precise adjustment as required.

[0027] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.

[0028] The foregoing description shall be interpreted as illustrative and not in any limiting sense. A person of ordinary skill in the art would understand that certain modifications could come within the scope of this disclosure.

[0029] The embodiments, examples and alternatives of the preceding paragraphs or the description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
