The present invention relates to a twisted yarn for manufacturing twisted twisted yarn (hereinafter referred to as "pumped yarn") attached to the edge of various flags or pennants (hereinafter referred to as "pumped yarn"), more specifically, twisted at a predetermined rotational speed. A winding device for winding a plywood to a drum.

In general, a plywood yarn for manufacturing a plywood is divided into a yarn supply unit for supplying a plurality of threads, a plywood part for twisting the yarns of several strands supplied from the yarn supply unit into one, and a yarn twisted in the plywood part. It consists of a winding part wound on a drum.

In addition, the thread supply unit is composed of a supply roller for transporting the center yarn and a plurality of guide rollers for guiding the multiple strands of the yarn coated on the circumferential surface of the center yarn, and the plywood part is a shaft that twists the thread transferred from the supply unit into one; Consists of a drive motor for driving the shaft, the winding portion is composed of a drum winding the twisted yarns in the braided portion and a drum reciprocating movement means for evenly wound around the circumferential surface of the drum.

Therefore, the multi-pneumatic twisting machine is equipped with a power transmission mechanism of various paths for transmitting power to each driving part (supply roller, shaft, drum, etc.), and the operation of the machine is smoothly performed only when the rotation ratio of each driving part is correctly maintained.

However, the conventional combination twister is a structure in which the rotational force of the shaft driving motor is transmitted to the drum through a number of power transmission gears (bevel gears, worm gears, etc.) so that the shaft and the drum are interlocked. Increasing the manufacturing cost, especially the gear ratio, the rotational ratio between the shaft and the drum is not maintained accurately, which causes a malfunction of the machine.

For example, the drum must be rotated at a certain rate slower than the shaft in the same direction as the shaft, so that twisted braided material is wound on the drum. If the drum speed increases due to gear tolerances, The result is that the drum is not wound well or is loosely wound. On the contrary, if the drum rotation speed is slow, the winding speed of the weaving yarn is faster than the feeding speed of the yarn, which causes the failure of the thread supply unit. there is a problem.

An object of the present invention is to rotate the drum at a desired speed without installing a separate power transmission mechanism for driving the drum, and also to reciprocate the drum by a predetermined distance in the axial direction by using the power of the shaft driving motor. The purpose of the present invention is to provide a joint winding device.

According to the object of the present invention described above, the drum is installed in a tightly fitted state on the circumferential surface of the shaft, and rotates the shaft and the drum at different speeds by applying a resistance force to the drum.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the present invention, and FIG. 2 is a side view in which the spool part twists and rotates a thread 2, a guide plate 4 fixed to the tip of the shaft, and a motor for rotating the shaft ( 1) and a belt 8 connected between the pulley 6 and the motor pulley 7 of the shaft, and the thread supplied from the thread supply part (not shown in the drawing structure) is a shaft of the shaft 2. It is wound on the drum through a hole (3) penetrated from the center to the outer surface and a hole (5) formed at one end of the guide plate (4).

Plywood winding portion is composed of a drum (9) that is tightly fitted to the outer diameter surface of the shaft (2) to rotate together with the rotation of the shaft, and a pressure mechanism for reducing the rotational speed of the drum by applying a resistive force to the drum.

In addition, the pressure mechanism is fixed to a pair of links (11) rotatably coupled to the support (10) with a pin, a connecting pin (12) penetrated between the links, and one end of the connecting pin (12) It consists of a friction plate 13 connected to the outer diameter surface of one side of the flange, and a spring 14 coupled to the link and always exerting a force downward.

Accordingly, the link 11, the connecting pin 12, and the friction plate 13 are pulled downward by the force of the spring 14 so that the friction plate 13 frictionally connects with the flange outer diameter surface of the drum. The rotational speed of the drum is reduced by the frictional force, and the friction plate 13 is formed in a magnetic cross section so as to surround the outer diameter surface of the flange.

The drum reciprocating mechanism for evenly winding the encirclement to the drum includes a speed reducer 15 for decelerating the power of the motor 1, a cam 16 fixed to a shaft of the speed reducer, and a cam 16 The first link 17 and the second link 18 and the driving piece that is fixed to the second link (18) by the pin (19) to rotate around the pin in accordance with the rotational movement of the cam ( 20) and a moving plate 21 on which a linear movement is possible at the rear of the drum and two stoppers 22 are fixed to one side thereof.

In addition, the upper end of the drive piece 20 is located between the stopper 22 of the moving plate 21, the moving plate 21 is coupled to the connecting pin 12 of the pressure mechanism by a fixing pin.

Therefore, when the cam 6 rotates, the driving piece 20 rotates. At this time, the upper end of the driving piece is caught by both stoppers 22 of the moving plate 21, and a rotational force is transmitted to the moving plate, thereby limiting the moving plate. In the drum direction, or moving in the direction of the drum in the direction of the eccentric distance, and the moving plate 21 is connected to the friction plate 13, since the connecting pin 12 combined with the moving plate moves together. The drum 9 is moved forward and backward by the amount of movement of the moving plate.

Reference numeral 23, which is not described in the drawings, is a speed reducer for transmitting the driving force of the motor to the actual supply portion.

The operation and effects of the inventive device as described above will be described.

First, the front end of the thread supplied from the thread supply part passes through the hole 3 formed in the shaft 2 and the hole 5 formed in one side of the guide plate 4, and then starts work in the state of being fixed to the drum 9. do.

When the motor 1 is driven in this state, the thread is supplied from the thread supply unit and the shaft 2 and the guide plate 4 rotate, and the thread supplied is twisted by the rotational operation of the shaft and the guide plate to be pulverized. .

Meanwhile, the drum 9, which is tightly fitted to the outer diameter surface of the shaft 2, rotates together in the rotational direction of the shaft. The drum rotates at a slower speed than the shaft because the rotational speed is reduced by the pressure mechanism. Since the envoy is wound on the drum (9).

In detail, the link plate 11, the connecting pin 12, and the friction plate 13 are pulled downward by the force of the spring 14 so that the friction plate 13 connected to the outer diameter surface of one flange of the drum 9 is connected to the drum. Since the pressure is applied to the drum, the rotational speed of the drum tightly fitted to the outer diameter surface of the shaft is reduced.

At this time, heat is generated by the friction between the friction plate 13 and the drum 9, but the heat generation is not a problem since the time when the plywood is completely wound on the drum is very short.

In addition, the rotation ratio of the shaft and the drum is determined by the tension of the spring 14, it is possible to match the winding amount of the yarn supply amount and the yarn feed according to the selection of the spring.

On the other hand, when the reducer 15 rotates, the cam 16 rotates and the driving piece 20 connected to the cam 16 by the first link 17 and the second link 18 is centered around the pin 19. , And the reciprocating rotation in the left and right directions by a certain angle and when the driving piece 20 is reciprocating rotation, the upper end of the driving piece is caught by the stopper 22 of the moving plate 21 to transfer the force to the moving plate. Since the movable plate is reciprocated, the connecting pin 12 coupled to the movable plate 21 by the fixing piece is also reciprocated.

Therefore, the drum 9 connected to the friction plate 13 on one side of the connecting pin is guided to the outer diameter surface of the shaft 2 by the movement of the connecting pin 12 and reciprocated for a predetermined distance, thereby causing the plywood to be drummed to the drum 9. Allows to wind evenly on the circumference of the

Since the movement amount of the drum 9 is proportional to the eccentric distance of the cam 16, an appropriate cam can be selected and used according to the width of the drum, and the stopper is not directly coupled to the moving plate 21. The reason why the driving force is transmitted through the 22 is to stop the movement of the drum 9 while the driving piece is idling between the two spotters so that the braided yarn is doublely wound at both flange portions of the drum.

As described above, unlike the conventional apparatus using a separate power transmission mechanism for driving the drum, the present invention is designed to rotate the drum directly on the circumferential surface of the shaft and to rotate the drum by another motor. Rotation operation and reciprocating movement of the drum are performed, so the overall structure of the machine is very simple.

As a result, the machine can be miniaturized and manufacturing costs can be reduced. The operation of each part is smoother than the conventional machine.
