Next, the operation of the device of the present invention will be explained.

In the yarn reeling tank 6 of the yarn reeling section 3, raindrops 15 are reeled off. The thread Y that has been taken out is the actual road device 9, the drum wheels 35, 34
The fineness is detected by a fineness sensor 37 through a kennel device 1o consisting of a drum wheel 16°41, an oiling device 13.
The yarn is introduced into the dryer 20 of the dry yarn winding section 4 through the guide 14. If the fineness of this quantity system Y decreases, the fineness sensor 3
7 senses this and releases the surface from the painting device 7 into the reeling tank 6 by a means not shown, and also rotates and swings the welding device 33 to release the surface from the painting device 7 into the reeling tank 6. The yarn is taken into the turning locus of the yarn take-in blade 32 of the welder, and the surface discharged into the yarn reeling tank 6 is welded to increase the fineness of the yarn to be taken up. In this way, the yarn Y is always reeled with a constant fineness and transferred to the dry yarn winding section 4. The yarn Y entering the dry yarn winding section 4 is wound around the dryer 2o. The dryer 20 receives the rotation of the motor 6o through the chain 61 to the main drive shaft 62, and the power is transmitted to the bevel gears 63, 66, the drive shaft 65, the clutch 68, the drive shaft 65, the bevel gear 67, and the bevel gear 54. The disc 65 integrated with the guide rod 54 rotates, and the guide rod 539 and the disc 56 also rotate together. At this time, the guide rod 53 revolves around the vertical axis 53 and winds the thread Y around the cylindrical guide rod 17. dryer 20
The thread wound a predetermined number of times is pulled out downward and wound onto the bobbin 84 of the wine goo 22.

The bobbin 84 contacts the winding drum 80 and receives the rotation of the winding drum 80 to wind up the yarn Y. The rotation of the motor 75 is transmitted to the winding drum 80 via an electromagnetic clutch/brake 76.

Under normal conditions, the electromagnetic clutch/brake 76 operates with the clutch engaged, and the winding drum 80 rotates.

In the above, the dryer 2o is always rotated at a constant speed by the motor 60, but the winding drum 8o of the winder 22 is adjusted to rotate at a slightly stray yarn winding speed than the yarn sending speed of the dryer 20. Therefore, as the yarn is wound onto the bobbin 84, the number of times the yarn is wound in the dryer 2o decreases. A fiber sensor 9 is installed on the side of the dryer 20.
Q is provided, and when the thread facing the fiber sensor 90 runs out, the light reflected from the thread will no longer enter the fiber sensor 90, and the sensor that detects this will issue a signal and activate the clutch of the electromagnetic clutch/brake 76. cut. As a result, the output of the motor 75 is no longer transmitted to the drum 80, and the drum 80 rotates by inertia, and its rotational speed gradually decreases. Therefore, the amount of yarn drawn out from the dryer 20 gradually decreases, and the amount of yarn wound around the dryer 20 gradually increases.
When the yarn reaches a position facing the fiber sensor 90, and the presence of the yarn is detected by the fiber sensor 90, a signal is generated, the electromagnetic clutch/brake 76 is engaged, and the rotation of the motor 75 is transmitted to the winding drum 80, causing winding. The drum 80 is energized and increases its rotational speed.

The yarn is continuously reeled by repeatedly turning on and off the clutch.

When a yarn failure occurs during reeling, the reeling tension increases, so the swinging rod 40 is pulled by the increased yarn tension and swings to the position shown by the chain line, and the microswitch 49 is pressed. In addition, when a light cut occurs, the thread breakage detection device 28 installed in the thread path is activated and sends a signal to the solenoid 46, which is activated, and the dogleg arm 44 is activated to pull the rod 47. Then, in order to pull the rod 47, the dog-shaped arm 44 turns in the hour'&] direction in the drawing and pushes the cam piece 42, which causes the swinging rod 40 integrated with the cam piece 42 to move in the counterclockwise direction. Turn to the position and press the micro switch 49 in the same manner as above. The operation of the microswitch 49 activates the brake of the electromagnetic clutch/brake 76, and the transmission of power from the motor 75 to the drum 8o is directly cut off and braked, so that the winding drum 80 immediately stops. At the same time, the microswitch 49 operates the solenoid 70 to pull the protrusion 1 and bring the brake shoe 73 into contact with the disc 66 of the dryer 20, thereby immediately stopping the dryer 20. At the same time, the electromagnetic clutch/brake 58 in the drive system of the dryer 2o is actuated by the microswitch 49, so when the solenoid 70 is actuated, the clutch is turned off and power transmission from the motor 60 to the dryer 2o is cut off. can perform braking.

As described in detail above, the apparatus of the present invention includes a reeling section which is provided with a practical passage device, a fineness sensing device, a yarn failure stopping device, etc. in the upper part of the reeling tank, and a reeling section that is equipped with It has a plurality of thread guide rods hanging concentrically, and the thread guide rods are supported so as to revolve and rotate around a vertical axis. In a yarn reeling device comprising a dryer that draws out yarn in the vertical axis direction below the shaft, a dryer braking device for stopping the rotation of the dryer, and a dry yarn winding section provided with a wine goo, the wine goo is driven. An electromagnetic clutch/brake is installed in the drive system between a drive source such as a motor and a winding means such as a winding drum, and when the yarn failure stop device is activated, the electromagnetic clutch is activated by a signal from the yarn failure stop device.・Since the brake and dryer braking device are activated to instantly stop the rotation of the dryer and winding drum, when a yarn failure occurs, the winding is stopped by a signal from the yarn failure stop device that senses it. Since the drive of the drum can be stopped immediately and the rotation of the dryer can also be stopped by braking, when a yarn failure occurs, the wine goo will not wind up the yarn more than necessary, and the occurrence of yarn breakage due to winding of the wine goo can be avoided. can be prevented.
