Description

RING SPINNING BOBBIN HOLDER ASSEMBLY

TECHNICAL FIELD

[0001] The present disclosure relates generally to field of textile accessories. More particularly, the present disclosure provides a bobbin holder assembly to facilitate gripping of the ring spinning bobbin from inside.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Spinning bobbins are major elements of textile industry that helps in spinning yam and fibers. On ring spinning, the ring bobbins are used to wind the yarn produced and needs to be replaced with empty bobbin. Number of cycles in replacing full bobbin with empty affects to the productivity. More the ring spinning bobbin content, more is the productivity. Every spinner tries to collect more yarn on bobbin. However, gripping the bobbin and holding the bobbin from inside is needed for increasing efficiency and productivity in textile industry. In some cases, due to need of gripping, area of the bobbin can remain empty for yarn content. Therefore, gripping or holding full and empty ring spinning bobbins from inner top side is needed.

[0004] Existing solutions can include ring spinning bobbins that can be gripped from top side approximately 15 mm approx from upper top which mandates the leaving bobbin empty from top side by 15 mm approx resulting in less yam content and frequent replacement cycles of full bobbins with empty bobbins. Ring spinning bobbin grippers are based on either piston mechanism or diaphragm mechanism, both operated by pressurizing air which leads to push the piston against fixed outer surface or filling air in diaphragm leading to ballooning and gripping the bobbin. As there is surface contact from outer end, functionality of such mechanism can be dependent on outer surface of bobbin roughness properties. However there are limitations for existing solutions like they require air to operate which increases cost of extra equipments such as compressor, necessity of passing air from source to destination. Also, performance of holding bobbins depends on bobbin outer surface and wear out rate of gripping elements such as piston gripping surface, diaphragm deformation etc & related addition of maintenance and replacement cost of elements after certain interval. [0005] There is a need to overcome above mentioned problems of the prior art by bringing a solution that can facilitate gripping or holding full and empty ring spinning bobbins from inner top side and helps in increasing productivity by allowing the yarn winding till the maximum bobbin top which results in reduction in more yarn content on same bobbin and less frequency to replace the full bobbins with empty. The solution aids in saving electricity cost required for generation of air pressure. The solution saves the cost of maintenance and replacement of parts such as piston, diaphragm etc. which are required for gripping and releasing the ring spinning bobbin. Also, the solution is completely enclosed, self-dependent and user friendly and enables providing dust and dirt free working mechanism.

The assembly (100) can include the spring (218) with optimum compressed or near to relax state, fixed outer presser guide (112) or casing (112), movable upper presser (108) withsliding fully downward in the slot of the fixed outer presser guide (112), movable inner presser (110) that can move downward up to stationary position, a movable arm (106) that can move downward up to stationary position, locking leg holder (104) that can reach extremely down with the one or more set of pair of locking legs (102) inside a bobbin (302). [0068] In an illustrative embodiment, when the assembly (100) moves up, the movable arm (106) can come out from the bobbin (302) contact and can lower down resulting in the movable inner presser (110) and lowering resulting in movable upper presser (108) lowering. While lowering, the movable upper presser (108) can enter in next set of teeth slots of the fixed outer presser casing (112) and can rests at bottom most position. In another illustrative embodiment, the locking leg holder (104) can move in lowermost position and the set of locking legs (102) can come in contact with a splitting pin (216) allowing the one or more set of pair of locking legs(102) to open which can grip the bobbin (302) from inside allowing lifting of the bobbin (302). [0069] In an illustrative embodiment, the assembly (100) can facilitate self-operating gripping ring spinning bobbin from top inner side, where the bobbin holder assembly (100) can enter easily inside the bobbin (302) from top. In another illustrative embodiment, pressing of the bobbin holder assembly (100) from bottom can allows to grip the bobbin (302) from top as well as second pressing can allow to release the bobbin (302) without any external element to operate.

[0070] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously.

[0071] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, ' components, or steps that are not expressly referenced. [0072] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
