Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an electric hand spinning machine, and more particularly, to an electric hand spinning machine with improved flyer yarn guide and bobbin brake mechanism.

[Prior art]

Although commercially available yarns are available in various colors, patterns, and thicknesses, they are inevitably uniform. As a recent trend, electric hand spinning machines are attracting attention as a hobby in order to obtain arbitrary patterns, thicknesses, and shapes of yarn.

Conventionally available electric hand spinning machines have the following general configuration. In other words, the flyer and bobbin are rotatably supported between a pair of side plates of the frame, and a brake mechanism is provided to control the rotation of the bobbin.The flyer is rotated around the bobbin by an electric motor, and the flyer is rotated for spinning. The yarn is fed in sequence and wound onto a bobbin while giving the desired twist.

By the way, when winding the spun yarn from the flyer onto the bobbin in a hand spinning machine, it is necessary to traverse the spun yarn in the axial direction of the bobbin and wind the spun yarn around the bobbin with an even thickness. For this reason, conventional electric hand spinning machines generally employ a structure as shown in FIG. 2.

According to the structure shown in Fig. 2, hook needles C1 to C5 are provided at equal intervals on each leg of the flyer A, and a person doing the spinning work can watch the winding of the spinning yarn D by the bobbin B. , flyer A of spinning D
From C1 to C2, change the supply position for bobbin B to C2.
It is designed to change in order between ~C3, ...C4 and C5.

Therefore, with conventional hand spinning machines, the spacing between hook needles is fixed regardless of the thickness of the thread being spun, making it difficult to wind the thread to an even thickness. In addition, the hook protruded outside the fryer, which was dangerous.

[Purpose of this invention]

The present invention was developed in view of the above circumstances, and includes a guide ring that can be moved with a single touch as a thread guide for the fryer, and a brake mechanism that is electrically operated, consisting of a coiled spring, a gut, a worm gear winding device, and a braking wheel. It provides hand spinning machines.

[Means to solve problems]

In the present invention, a guide ring 2 is attached to a fryer 1.

The flyer 1 is provided with a groove 3, and the guide ring 2 is provided with a guide hole 5 through which the thread 4 passes and a fitting hole 6 for fitting into the flyer 1. One end 7 of the guide ring 2 is somewhat thick and has a pin 8 embedded therein. This pin 8 fits into the groove 3 of the fryer and ensures that the guide hole 5 of the guide ring 2 always faces in the same direction of the fryer.

The fitting hole 6 of the guide ring 2 has a substantially oval shape. As a result, the guide ring and the flyer are usually fixed at the EE′ point of the guide ring.
The guide ring allows the spun yarn to be wound onto the bobbin at a fixed position without shifting laterally. The guide ring is then slid laterally in accordance with the winding state of the bobbin. For sliding, by pressing the FF' point of the guide ring with your finger, a gap is created at the EE' point, which was press-fixed, and sliding becomes possible. When you release your finger after sliding it to the desired position, the gap at point EE' disappears and the guide ring is fixed to the fryer.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained in detail based on FIG.

In the figure, 1 is a flyer, and 10 is a bobbin. The flyer 1 and bobbin 10 are rotatably supported between a pair of side plates 12 and 13 of a frame 11, and are driven by a motor 14 via a belt 15 and a pulley 16. While rotating the flyer, raw material cotton such as wool is supplied from the yarn opening 17, and the spun yarn is sequentially supplied to the guide hole 5 of the guide ring 2 of the flyer and wound onto the bobbin 10 while giving the desired twist. ing.

At least one guide ring 2 is required at the base of the flyer and one at the winding position. Note that the guide ring at the base does not necessarily have to be slidable.

A guide ring is also provided on the other flyer's leg so that the guide holes face the same plane as shown in Figure 1, the spinning is supplied to this ring, and the motor is rotated in the opposite direction to rotate the flyer and bobbin in the opposite direction. By doing so, it is also possible to spin S-twisted yarn instead of normal Z-twisted yarn.

Since it is possible to apply both Z-twist and S-twist, it is also possible to make a double yarn by using two Z-twist yarns and applying S-twist.

The rotation of the bobbin is controlled by a brake mechanism. For the brake, a coiled spring 19 is fixed to a stopper 18, and one end of the coiled spring is connected to a gut 20, which is connected to a groove 2 of a braking wheel provided at one end of a bobbin.
1. It passes through the guide tool 22 and is wound up by the winding tool 23. The gut may be a thread with low elongation. The winder is equipped with a worm gear that is used to tension guitar strings. Since the winding tool is wound only a small amount even if the knob 24 is rotated once, the tension of the string can be adjusted, that is, the degree of application of the brake can be finely adjusted.

〔effect〕

In this invention, the guide ring attached to the flyer is always fixed and can be slid to the left or right by the desired amount with a single touch when desired. The guide ring can be moved by rotating the spindle, making it possible to spin yarn with a more uniform yarn thickness and number of twists.

Additionally, the brake mechanism can be finely adjusted depending on the condition of the spun yarn, making it easier to spin the yarn of your choice.
