Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a turret type winder for continuously winding yarns such as synthetic fibers and glass fibers.

[Prior art]

In general, a turret type winder that continuously winds yarns such as synthetic fibers and glass fibers has a turret drum on which a plurality of bobbin tightening spindles are rotatably mounted on a shaft mounted on a machine base. The spindle is rotated freely to the winding operation position and the doffing operation position, and the bobbin mounted on the spindle contacts the touch roller or the driving roller installed at the winding operation position. At least, the yarn is wound around a bobbin while being traversed by a traverse device. When a predetermined amount of yarn is wound, the turret drum rotates to move the full bobbin in the winding operation position to the doffing operation position and move the empty bobbin in the doffing operation position to the winding operation position. Then, the yarn is continuously wound. In the above-described turret type winder, the hinge is rotatably mounted on the turret drum by a bearing such as a ball bearing, and the bearing is lubricated by grease or the like. In the above-described configuration in which the ball bearing is filled with a predetermined amount of grease and lubricated, a sufficiently satisfactory cooling effect cannot be obtained even if a lubricating effect can be obtained.
Therefore, when the winding speed of the yarn is as high as 3000 m / min or more, the temperature of the bearing part becomes high and the grease deteriorates,
The life of the bearing is shortened. Therefore, the bearing had to be replaced frequently.

[Problems to be solved by the invention]

If grease is used to lubricate the bearings supporting the spindle in the turret type winder described above, a sufficient cooling effect cannot be obtained, and when the winding speed is high, the life of the bearing is shortened, and the bearing is frequently replaced. The point that must be done.

[Means for Solving the Problems]

In order to solve the above-mentioned problem, a turret type winder according to the present invention has a shaft body in which an oil mist supply hole corresponding to a bearing portion of each spindle is formed in a shaft body, and the turret drum is provided with the oil mist supply hole. A communication hole for connecting the oil mist supply hole of the shaft and the spindle mounting bearing portion is formed, so that the oil mist can be independently supplied to the bearing portion of each spindle. According to a second aspect of the present invention, the oil mist is supplied only to the bearing portion of the rotating spindle, or an oil mist suction hole is formed in the shaft body and the turret drum is provided. It is also possible to provide a structure in which a communication hole is formed in the shaft to suck and discharge the oil mist supplied to the bearing portion of the spindle.

An O-ring 21 is inserted into a groove 7p formed on the peripheral surface of the shaft body 7. Reference numeral 22 denotes a brake for stopping the rotation of the spindle that has reached the doffing operation position. When the winding operation of the yarn is performed by the turret type winder described above, the bobbin 30a is tightened to the spindle 1 at the doffing operation position. Then, the turret drum 3 is rotated to move the spindle 1 to the winding operation position and the spindle 2 to the doffing operation position. In this state, the bobbin 30b is tightened to the spindle 2. When these preparations are completed, the traverse device 12 is lowered to bring the drive roller 13 into contact with the bobbin 30a, and the drive roller 13 starts and rotates at a preset speed. Simultaneously with the drive roller 13 starting operation,
Alternatively, the electromagnetic switching valve 18 is actuated immediately before the start operation, the oil mist supply pipe is connected, and the oil mist is supplied from the oil mist supply pipe 15 to the oil mist supply hole 7 a of the shaft 7. Then, the oil mist has pores 7d, 7e,
Grooves 7i, 7j and pores 3a, 3b of turret drum 3
To the bearings 4a, 4b. At the same time as the supply operation of the oil mist, a suction force acts on the oil mist suction pipe 20. Therefore, the oil mist supplied to the vicinity of the bearings 4a and 4b and passed through the bearings 4a and 4b is supplied with the fine holes 3e of the turret drum 3, the grooves 7n and the fine holes 7h of the shaft body 7, and the oil mist suction holes 7c. The oil is discharged from the oil mist suction pipe 20 through the pipe. When the rotation speed of the bin 30a reaches the preset winding speed by the driving roller 13, the yarn is wound around the bobbin 30a and wound by the traverse device 12 while traversing. Then, when a predetermined amount of yarn is wound,

Next, the spindle 2 at the doffing operation position is started to be driven by a run-in roller (not shown) by a preset timer or the like. Simultaneously with this operation, or immediately before the start of driving, the electromagnetic switching valve 19 operates to operate the oil mist supply pipe 16 and the oil mist supply main pipe 17.
When the rotational speed of the spindle 2 reaches a preset rotational speed, the electric motor is operated to rotate the turret drum 3 by 180 ° and the full bobbin 30a to the doffing operation position,
The empty bobbin 30b at the doffing position is moved to the winding operation position. When the turret drum 3 rotates by 180 ° and the spindle tightening the full bobbin stops by the brake 22,
The electromagnetic switching valve 18 is actuated to switch the oil mist supply pipe to stop the supply of the oil mist. Spindle 1 or spindle 2 as described above
During the winding, supply and discharge operations of the oil mist are performed. As described above, since the oil mist can be reliably supplied from the shaft body 7 installed on the machine base 5 to the bearing 4 of the turret drum 3, both lubrication and cooling effects can be obtained, and the life of the bearing can be obtained. Becomes longer. In addition, since the oil mist is supplied to the bearing 4 and the oil mist that has passed through the bearing 4 is sucked and discharged, the oil mist does not stay in the bearing 4 and fresh oil mist can always be supplied to the bearing 4. . Furthermore, since the oil mist is supplied only to the bearing 4 of the rotating spindle, the consumption of the oil mist can be reduced.

【The invention's effect】

In the turret type winder according to the present invention, an oil mist supply hole corresponding to a bearing portion of each spindle is formed as described in claim 1, and an oil mist supply hole of the shaft and a spindle mounting hole are provided in a turret drum. The oil mist is supplied to the spindle bearings independently by drilling a communication hole to connect the bearings of the spindles and supplying the oil mist to the bearings of each spindle independently. And both lubrication and cooling effects can be obtained. Therefore, the life of the bearing is prolonged, and the machine stoppage time due to the bearing replacement work can be reduced. Further, when the oil mist is supplied only to the bearing portion of the rotating spindle, the consumption of the oil mist can be reduced. Further, it is preferable that an oil mist suction hole is formed in the shaft body, and a communication hole is formed in the turret drum, so that the oil mist supplied to the bearing portion of the spindle is sucked and discharged. In addition, the oil mist does not stay in the bearing portion, and fresh oil mist can always be supplied to the bearing portion.
