Patent No. 10 - 0562713 - 0000 Patent No. 10-0990409-0000 Patent Application No. 10 - 2004 - 0048107 Patent Application No. 10 - 2009 - 7016210

When the yarn is to be wound using the yarn winding device using the above-described conventional technique, the yarn is wound on the surface of the core such as a bobbin, a cylinder, or a core wound substantially, It is generally used in a state in which a wound bobbin, cylinder or branch tube is held.

When the yarn is wound on the surface of a core material such as a bobbin, a cylinder or a branch tube, since the core is wound in a direction perpendicular to the axial center of the core material, the wound shape becomes the same cylindrical shape as the core material as a whole.

In the case of using the bobbin, cylinder or paper tube as described above, when the means (machine) for maintaining the bobbin, the cylinder or the branch tube in a normal state is adopted, the speed at which the thread is released can be maintained in an appropriate state It is true that there is no great difficulty.

However, where the yarn is rolled and used where it is unrelated to ordinary fibers, for example, in the construction site to construct a building or structure, the placement of concrete, the masonry or other structure of tile or brick or block, In order to display the operation line for installation on the main body (in the form of an umbrella).

In order to display the work line in the field, one of the two workers at the starting position for displaying the work line takes the bundle of the thread wound, the other holds the end of the thread and moves to the end position of the work line And takes the form of displaying a work line.

Since the length of the work line ranges from several meters to tens of meters, the two workers must always move from the start position to the end position of the work line, so that the work progress is slow and one person is wound In some cases, the bundle is placed on the ground, while the other thread is holding the loosened yarn and pulling on the end of the yarn.

In this case, due to the pulling force of the yarn, the bundle in which the yarn is wound is rapidly or slowly released by the irregular bounce and the movement, and the back lash phenomenon occurs in which the yarns are tangled to each other. It takes more time and the operation speed is slowed down.

This is because the yarn bundle is rotated by the pulling force of the yarn since it is loosened from the outer surface of the wound yarn. In order to keep the shape of the bundled yarn even though it is desired to pull the yarn from the inner side of the yarn bundle Since there is a core material (bobbin, cylinder or paper tube), it is impossible to pull out the inner side.

In the case of removing the core material from the inside of the bundle to which the yarn is wound, the yarn can not maintain the shape of the yarn and the four layers are collapsed, so that it is practically impossible to draw the yarn through the inside It is a fact that it is occurring.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above problems, and it is an object of the present invention to provide a power box having a power means for generating power necessary for winding a yarn, And a winding guide provided on either side of the power box for receiving the power of the power means and winding the yarn evenly on the spindle from the side of the spindle;

It is possible to maintain the shape of the yarn even when the yarn is wound without core and to keep the shape of the yarn continuously. The yarn is drawn from the inside of the wound yarn bundle and used, so that the yarn can be used smoothly without tangling and twisting This is possible.

In the present invention, the yarn is wound in a slanting line (or a spiral shape) which is sequentially deviated with respect to the axial center of the spindle without a core material, so that the completed overall shape becomes an elliptical shape, It is possible to draw out the thread located inside the bundle, thereby facilitating withdrawal of the yarn from the bundle of yarn, thereby increasing the convenience of users.

The yarn winding device 100 to which the technique of the present invention is applied is provided with a hexahedral power box 105 having the power means 110 so as to generate the power necessary for winding the yarn 101, The output shaft 106 taken out to the front of the power box 105 is provided with a spindle 120 for winding the yarn 101 substantially.

A winding guide 130 for receiving the power of the power unit 110 to uniformly wind the yarn 101 on the spindle 120 from the side of the spindle 120 is provided on either side of the power box 105 And configure it.

The power unit 110 includes a motor 111 installed on one side or the other side of the inside of the power box 105 and a power transmission unit such as a pulley and a belt, And the output shaft 106 is installed so as to protrude forward from the upper portion of the power box 105.

The chain gear 113 is fixed to the output shaft 106 and connected to the chain gear 115 by a chain 116 fixed to an intermediate shaft 114 provided below the power box 105, 114 are fixed to the bevel gear 117 so as to be engaged with the bevel gear 119 fixed to the drive shaft 118 projecting sideways of the power box 105 in a direction perpendicular to the intermediate shaft 114, Thereby transferring the power that can move the motor 130.

The power box 105 is closed with a cover or the like so as to prevent foreign substances from flowing into the inside of the power box 105 while preventing the noise generated during the operation of the power unit 110 from flowing out to the outside, .

The spindle 120 is formed by fixing a metal or plastic rod to an output shaft 106 exposed to the outside (front side) of the power box 105, The yarn 101 at the winding start position is hooked and fixed so that the yarn 101 located inside the yarn bundle 125 can be taken out while the yarn bundle 125 is separated from the spindle 120 after the winding of the yarn is completed The fixing means 126 is provided.

The fixing means 126 may be constructed in various ways such as a locking slot formed integrally with the spindle 120 or a locking protrusion or a locking hook separately fixed to the spindle 120, Do not.

The winding guide 130 connects the operator 132 with the hinge pin 133 on the front side of the guide bracket 131 fixed to the side of the power box 105 and projecting forward, Is connected to the driving shaft 118 protruding sideways of the power box 105 and the front end of the connecting rod 135 so as to be reciprocated in the axial direction of the spindle 120.

The rear end of the connecting rod 135 is eccentrically connected to a rotating plate 136 fixed to the driving shaft 118 to transmit the rotational motion of the driving shaft 118 in a linear motion to move the actuator 132.

A guide bar 140 is fixed to the upper side of the actuator 132 and a guide bar 140 is fixed to the end of the guide bar 140 to guide the thread 101 wound on the spindle 120 Guides 141 are provided.

The distance L between the upper end of the guide bar 140 and the intermediate position of the spindle 120 and the distance L 1 between the rear position and the forward position when the guide bar 140 is moved rearward and forward of the spindle 120 And L2 of the spindle 120 make the interval L of the intermediate position of the spindle 120 to be larger so that the guide bar 140 oscillates backward and forward of the spindle 120 to make the thread bundle 125, .

The rotation speed of the spindle 120 is made slower than the speed at which the guide bar 140 performs the arc motion and the guide bar 140 is reciprocated at a speed of 1.2 or 1.3 times that of the spindle 120 when the spindle 120 makes one rotation. (Or spirally) in the axial direction of the spindle 120, and the yarn 101 is wound at a position that is out of the position of the yarn 101 wound earlier than the rotation speed difference without forming the four layers at the same position So that unequal four layers are formed naturally.

A process of winding the yarn 101 using the yarn winding device 100 to which the technique of the present invention is applied will be described as follows.

The yarn winding device 100 may be used in an independent state or may be provided with a separate frame and then the yarn winder 100 may be connected to the frame in series, It can be used in various forms.

The yarn 101 to be wound is taken out from the wound bobbin and passed through a plurality of yarn guides and then connected to the spindle 120 via a guide 141 fixed to the end of the guide bar 140 of the winding guide 130 The spindle 120 is wound one or more times to prevent unwinding of the yarn 101 during the initial winding and the end of the yarn 101 is connected to a fixing means 126 further provided on the spindle 120 The yarn 101 can be taken out from the inside of the yarn bundle 125 when the yarn bundle 125 is removed from the spindle 120 after the winding is completed.

When the motor 111 is operated in the state that the winding preparation is completed as described above, the power of the motor 111 rotates the spindle 120 through the output shaft 106 and the driving shaft 118 to rotate the rotating plate 136 fixed to the drive shaft 118 exposed to the side of the power box 105. [

The connecting rod 135 is connected to the rotating plate 136 to convert the rotational motion into a rectilinear motion. The connecting rod 135 is fixed to the side of the power box 105 and has a guide bracket 131 protruding forward. And the actuator 132 connected to the hinge pin 133 is reciprocated forward and backward with respect to the guide bracket 131.

Since the guide bar 140 is connected to the upper portion of the actuator 132 so as to be inclined in the direction of the spindle 120, the guide bar 140 is also reciprocated in the forward and backward directions of the guide pins 120 .

Since the guide bar 140 for supplying the thread 101 to the spindle 120 from the outer surface of the spindle 120 rotating in this manner continues to reciprocate in the axial direction of the spindle 120, Since the rotation speed of the spindle 120 and the rotation speed of the guide bar 140 are fast, the yarn 101 wound around the spindle 120 is always wound on the same surface (spiral) It is possible to maintain the shape that is wound slightly before the first wound position without being wound at the position.

The range of reciprocation of the guide bar 140 is the same in the initial stage of winding the yarn 101 on the spindle 120 but is wound on the spindle 102 because the distance between the spindle 120 and the guide bar 140 is too long It is difficult to confirm the route through which the yarn 101 is wound while the yarn 101 is initially wound in a tight state on the outer surface of the spindle 120. However, The route through which the thread 101 passes by the thread bundle 125 clearly becomes visible. As a result, as shown in FIG. 7, the position of the thread 101 is not always constant and the spindle 120, The gap of the thread bundle 125 is larger than that of the guide 130 so that traces such as holes are left between the seat 101 and the seat 101 as the size of the thread bundle 125 increases.

After the thread bundle 125 is completed, the thread bundle 125 is pulled out from the spindle 120 to pull the thread bundle 125 out of the thread bundle 125. In this state, It is possible to maintain the shape of the four layers without collapsing.

Even if the yarn 101 is drawn out from the inside of the yarn bundle 125 and used, the yarn bundle 125 can be maintained without collapsing. Therefore, when a work line is to be formed on the site for building or structure building work One operator has the advantage of being able to connect or display the work line easily by holding the thread bundle (125) in the starting position of the work line and the other at the end of the work line.

In addition to the purpose of displaying a work line in the field of building construction or structure, it is possible to prevent irregular movement of the thread bundle 125 even in general use, that is, knitting, and to eliminate the phenomenon of thread tangling .
