The present invention relates to fibrous roving spinning systems and, more specifically, to a spinning flyer having a level wind system.
A typical spinning system for making yarn and the like employs a flyer to spin fibrous roving in a single (a single strand in yarn) and then wind the single onto a bobbin. Traditional spinning systems employ a series of hooks disposed along one an arm of the flyer to guide the roving onto the bobbin. As one portion of the bobbin is filled up, the user moves the roving from one hook to an adjacent hook to start filling an adjacent portion of the bobbin. Some spinning systems employ a moveable guide that the user moves along the arm to distribute the roving on the bobbin. Both of these types of systems require the user to stop spinning either to change hooks or to move the guide.
One system employs a mechanical level wind gear that automatically moves the guide during the spinning operation. However, this system requires a complex set of gears, including a special type of geared bobbin, to operate. It cannot be used with a conventional bobbin and the special bobbins tend to be more expensive than conventional bobbins.
Existing level wind systems for arts and craft applications were mechanically geared or belt driven with the need for special bobbins and equipment, making such devices costly due to custom components required.
Therefore, there is a need for a flyer that has a level wind system that automatically moves the guide during spinning, but that can be used with conventional bobbins.
The disadvantages of the prior art are overcome by the present invention which, in one aspect, is a flyer for spinning a fibrous roving onto a bobbin and configured for use with a spinning system. A housing defines a central hole passing therethrough. A center rod passes through the housing and is rotated by the spinning system. The center rod supports the bobbin and defines a passage that opens to a center hole that is in alignment with the central hole of the housing so that the fibrous roving passes into the center rod through the passage and out through the central hole of the housing. An electric motor is affixed to the housing. A battery is contained in the flyer and powers the electric motor. A hollow level wind frame is affixed to the housing and parallel to the center rod. The hollow level wind frame defines an elongated slot passing therethrough. A level wind gear is disposed in the level wind frame and is rotated by the electric motor. A level wind carriage system is driven by the level wind gear so as to oscillate repeatedly between a first end and a second end as the level wind gear is rotated. The level wind carriage system includes a pawl that is engaged with the level wind gear and a guide that is coupled to the pawl. The guide passes through the elongated slot defined by the level wind frame. The fibrous roving passes through the guide.
In another aspect, the invention is a spinning flyer for spinning a fibrous roving onto a bobbin and configured for use with a spinning system. A housing defines a central hole passing therethrough. A center rod passes through the housing and is rotated by the spinning system. The center rod supports the bobbin. The center rod defines a passage that opens to a center hole that is in alignment with the central hole of the housing so that the fibrous roving passes into the center rod through the passage and out through the central hole of the housing. An electric motor is affixed to the housing. A battery is contained in the flyer and powers the electric motor. The battery is electrically coupled to the electric motor via a switch. A hollow level wind frame is affixed to the housing and is parallel to the center rod. The hollow level wind frame defines an elongated slot passing therethrough. A level wind gear is disposed in the level wind frame and is rotated by the electric motor. A level wind carriage system is driven by the level wind gear so as to oscillate repeatedly between a first end and a second end as the level wind gear is rotated. A pawl is engaged with the level wind gear. A guide is coupled to the pawl and passes through the elongated slot defined by the level wind frame. Fibrous roving passes through the guide. A balance rod is affixed to an opposite side of the housing from the hollow level wind frame and the batteries are disposed in the balance rod. A drive pulley is affixed to the housing and receives rotational force from the spinning system. The drive pulley rotates the housing and the level wind frame about the center rod.
In yet another aspect, the invention is a system for use in spinning a fibrous roving that includes a frame. An electric motor is coupled to the frame. A battery is attached to the frame and is configured to power the electric motor. An elongated bi-directional level wind gear has a first end and an opposite second end. The level wind gear is supported by the frame and is rotated by the electric motor. A level wind carriage system is driven by the level wind gear so as to oscillate repeatedly between the first end and the second end as the level wind gear is rotated. The level wind carriage system includes a pawl that is engaged with the level wind gear and a guide that is coupled to the pawl and that is affixed to the pawl. The fibrous roving passes through the guide.
These and other aspects of the invention will become apparent from the following description of the preferred embodiments taken in conjunction with the following drawings. As would be obvious to one skilled in the art, many variations and modifications of the invention may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. The present disclosure should in no way be limited to the exemplary implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.”
As shown in
An electric motor 144, such as a D.C. electric motor, is affixed to the housing 110 and a battery 142 (which can include a plurality of cells) via a switch 146 that selectively electrically couples the battery 142 to the electric motor 144. The battery 142 is contained in the flyer 110 and powers the electric motor 144. A balance rod 140 is affixed to an opposite side of the housing 110 from the hollow level wind frame 130. The batteries 142 may be disposed in the balance rod 140.
A hollow level wind frame 130 is affixed to the housing 100 so as to be parallel to the center rod 120. The hollow level wind frame 130 defines an elongated slot 132 passing therethrough. A level wind gear 150 (i.e., a bi-directional worm gear) is disposed in the level wind frame 130 and is rotated by the electric motor 144. The housing 110 can be made of such materials as a machined metal, such as aluminum, or a plastic. The center rod 120, the balance rod 140 and the hollow level wind frame 130 can be made, for example, of aluminum tubing.
A level wind carriage system 133 is driven by the level wind gear 150 so as to oscillate repeatedly between the first end 152 and the second end 154 as the level wind gear 150 is rotated. The level wind carriage system 133 includes a pawl 138 that is engaged with the level wind gear 150 and a guide 136 that is coupled to the pawl 138. The guide 136 passes through the elongated slot 132 and is affixed to the pawl 138.
For use with certain types of spinning systems (such as those referred to as “Scotch tension spinners,” “Irish tension spinners” and “double drive spinners), a drive pulley 210 is affixed to the housing 110 and receives rotational force from a belt 208 coupled to the spinning system. The drive pulley 210 rotates the housing 110 and the level wind frame 130 about the center rod 120.

The battery powered level wind system of the present invention allows fiber processors to evenly distribute twisted fiber onto any bobbin, shaft or core without the need of manually or mechanically powering the system. The battery powered level wind system enables one to evenly distribute and level wind fiber, string or cable onto any bobbin, shaft or core. The battery powered level winder does not require special bobbins or other components to operate. It is a simple device that can be added to any machine to enable one to level wind. The battery powered level wind system is not brand or manufacturer specific and can be adapted for many uses. Spinning wheels, electric powered spinning wheels, bobbin winders or skein winders.
To operate one embodiment of the system, the following steps can be executed:
When the worm screw turns it will then move the level wind carriage back a forth along the frame assembly tube. The material passing though the Feed Loop of the guide will be distributed onto a spinning bobbin, shaft or core—resulting in an even distribution of material to save space for more material to be processed easily later.
