Description

[Detailed Description of the Invention] The present invention relates to a twisted cord manufacturing device, and more particularly to a device for automatically winding a tape around a core yarn.

BACKGROUND ART Conventionally commonly used twisted cord manufacturing apparatuses often employ a method of directly winding a bobbin winding tape around a spindle.

Therefore, since the bobbin is attached directly to the spindle, the width of the winding tape wound around the bobbin and the dimensions of the core yarn make it difficult or impossible to always obtain a constant twist, which results in a large number of twists. In addition, since the spindle is rotated by a motor via a belt, it is not possible to evenly wrap the winding tape around the core yarn. What's more, winding can cause troubles in operation, which causes many obstacles in operation, making it impossible to obtain uniform and homogeneous products, and reducing the product value. I was letting it happen.

The present invention was devised to eliminate the defects and inconveniences of the conventional devices as described above.
Insert the bobbin into the spindle and remove it from paper foil etc.
A device that produces a spiral twisted string by inserting a core yarn made of general fibers such as paper, silk, nylon, etc. into the axial cavity of the spindle, and then wrapping a winding tape around the core yarn by rotating the spindle. In this method, a bobbin receiver is provided with a cylindrical shaft hole formed in the center and two guide pins attached symmetrically to the circumferential edge surface, and the winding tape is applied to the receiver via a spindle. Insert the wound bobbin, insert and fit a fitting material for preventing vibration of the bobbin, and further install two guide pins symmetrically in the upper notch of the spindle to guide the guide pins and the saucer. By automatically winding the core yarn within the notch of the spindle through the pin, a uniform and high quality twisted cord is always provided regardless of the width of the winding tape and the dimensions of the core yarn. The object of the present invention is to provide an automatic winding device for winding tape in a twisted string manufacturing machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic winding device for winding tape in a twisted string manufacturing machine according to the present invention will be described below with reference to the drawings.

Figure 1 is an exploded view of the members of the proposed device and their assembly.
is the spindle.

As shown at the top of this figure, a notch 2 of an appropriate length is formed at the upper end of the spindle 1, and a shaft stop 3 is molded at the lower end.

Reference numeral 4 designates a belt hanging portion 4 for rotating the spindle 1, and reference numeral 5 designates a cavity provided at the axis of the spindle 1.

Reference numerals 6 and 6' designate screw holes into which guide pins 7 and 7' are screwed.

Reference numeral 8 denotes a receiving tray that is inserted into the spindle 1 and on which the hobbin 14 is placed.

The saucer 8 is shaped into a circular shape and has a shaft hole 10 and a cylindrical protrusion 9 at the outer lower part of the center.

This protrusion 9 is further provided with a screw hole 11 for fixing the saucer 8 to the spindle 1.

12 is its fixing pin.

13 is a guide pin 7.7' attached to the spindle 1.
This is a guide pin of the same type as that attached to the circumferential edge surface of the saucer 8.

15 is a winding tape that is wound around the bobbin 14, and is made by appropriately cutting and wrapping material such as paper, cloth, nylon, Tetron, aluminum, etc., and is usually called Tetron foil, aluminum foil, or paper foil. This is what is happening.

16 is a shaft hole of the bobbin 14, which, like the shaft hole 10 of the saucer 8, is a shaft hole into which the spindle 1 is inserted.

Reference numeral 17 denotes a fitting material for fitting onto the upper surface of the bobbin 14, and a shaft hole 18 is provided in the center.

This fitting material 17 is installed to prevent vibration shaking, lifting, etc. that occur when the pobbin 14 rotates.
A bobbin that matches the shape and weight of the bobbin 14 is prepared in advance, and a bobbin of an appropriate shape and size can be attached and detached each time it is used.

Next, the method of assembling the present device and its operation will be explained in conjunction with FIG. 2A. First, the shaft hole 10 of the saucer 8 is inserted into the spindle 1 shown in FIG. is stopped on the upper edge surface of the belt hanging part 4, and each fixing pin is screwed into each screw hole 11.

Then, the saucer 8 is fixed to the spindle 1.

Next, the shaft stop 3 of the spindle 1 is fixed to the fixing base 20 using the shaft support 19.

At this time, the rotating belt 21 of the motor (not shown) is attached to the belt hook 4 of the spindle 1.

The spindle 1 with the saucer 8 fixed in this way is placed on the fixing base 20.
Once the shaft hole 16 of the desired hobbin 14 is fixed to the spindle 1, the shaft hole 16 of the desired hobbin 14 is inserted into the spindle 1, and the hobbin 14 is placed on the tray 8.

When placing this pobbin 14, fit the fitting material 1 of appropriate weight.
7 needs to be fitted into the pobbin 14.

If the pot bin 14 is set in the saucer 8 in this way,
The core yarn 24 prepared in advance is inserted into the cavity 5 of the spindle 1 through the glue tank 25, wound around a separate winding cylinder 22 through the rollers 23, and further wound around the pobbin 14. By manually winding the tape 15 around the core thread 2 to 3 times through the saucer 8 and the guide pins 13 and 7 of the spindle 1, the state shown in Fig. 2A will be obtained.If the motor is further driven, the hobbin 14 will be The winding tape 15 is wound around the winding cylinder 22 while being wound around the core yarn 24.

Although the rotation motor of the winding cylinder 22 is not shown, it is driven by the same motor that rotates the spindle 1.

That is, since the glued core yarn is communicated within the spindle 1 and is always moved at a constant speed by the rotation of the winding cylinder 22, the winding tape 15 of the bobbin 14 is attached to the core yarn 24 by centrifugal force. At the same time, a spiral strand 26 (shown in the opening of FIG. 2) is formed at equal intervals within the notch 2 of the spindle 1.

The positions and lengths of the guide pins 13 and 7 at this time are related to the rotational speed of the spindle 1, so it is necessary to determine their positions in advance.

Furthermore, by changing the direction of the guide pins 13 and 7, the rotation can be changed, so that it is possible to freely operate the guide pins for left-hand winding and those for layer winding.

This invention is structured as described above, so paper, cotton, silk,
No matter what material the core yarn and wrapping tape are made of, such as nylon or Tetron, or regardless of the size of the core yarn or the width of the wrapping tape, it is possible to always create a twisted string with a constant and uniform spiral shape. Therefore, it can be used not only for textile threads, but also for producing colored decorative threads and strings.Moreover, the equipment itself is simple and easy to handle, making it practical and economical. It can be said to be an automatic winding device for winding tape in a new and unique twisting cord manufacturing machine.
